Diabetic kidney disease (DKD) is a major complication of diabetes mellitus. One third of patients with advanced diabetes mellitus can develop to uremia, which seriously endangers people’s health. In recent years, with the improvement of people’s living standards and the increasing incidence of diabetes, it has become the main cause of end stage renal disease in China. Over the past two decades, the understanding of diagnosis and treatment of DKD has been improved, such as putting forward the new concept of normoalbuminuric DKD and developing a variety of new anti-diabetic drugs. However, at present, the basic strategies of DKD treatment are still lifestyle modification, glucose control, blood pressure control and lipid control.

Objective To evaluate the implementation effects and problems about quota payment of specific diseases for hyperplasia prostate and ureteral calculi in Chengdu. Methods Payments, man-time of operation, and the lengths of hospitalization of hyperplasia prostate and ureteral calculi as quota payment of specific diseases in Chengdu from 2013 to 2015 were analyzed by using SPSS 16.0 software. Results Based on the standards of medical expense limitation in Chengdu unchanged, tertiary and secondary hospitals remained surplus with quota standards of single diseases unchanged. The average lengths of hospitalization of hyperplasia prostate and ureteral calculi in tertiary and secondary hospitals were significantly decreased (P<0.05). Conclusion The application of quota payment policy for single disease in Chengdu city of Sichuan province has been proved to work on controlling the medical expense of treating hyperplasia prostate and ureteral calculi. Our results indicate the continuous implementation of quota payment policy. However, the exploration of proper payment standardization, enhance of hospital supervision and establishment of efficient system are still needed to define.
Objective To study the effect of perioperative nutritional support on protein metabolism and immunity in patients underwent liver transplantation. Methods A total of 80 patients who underwent liver transplantation in our hospital from March 2015 to March 2016 were collected retrospectively, and then the 80 patients were divided into control group (n=40) and observation group (n=40) according to the type of perioperative nutritional support. Patients of control group didn’t receive preoperatively nutritional support, and received total parenteral nutrition support before postoperative exhaust, then received enteral nutrition support after anal exhaust. Patients of observation group receive preoperatively nutritional support before surgery, and received parenteral nutrition and enteral nutrition support before postoperative exhaust. The several parameters about nutritional status and immune function were observed on 7 days and 14 days after liver transplantation, and comparison of the 2 group in these parameters was performed. Results On the protein metabolism, the levels of serum transferrin, prealbumin, and nitrogen balance on 14 days after liver transplantation were higher than those of other time points (before liver transplantation and 7 days after liver transplantation),P<0.05, both in control group and observation group. There was no significant difference in the levels of serum transferrin, prealbumin, and value of nitrogen balance between the 2 groups before liver transplantation (P>0.05). But on 7 days and 14 days after liver transplantation, the levels of serum transferrin, prealbumin, and value of nitrogen balance of the observation group were higher than those of control group (P<0.05). On the immunity, the total number of lymphocytes, value of IgG and CD4/CD8 on 14 days after liver transplantation, were superior to other time points (before liver transplantation and 7 days after liver transplantation),P<0.05, both in control group and observation group. There was no significant difference in the total number of lymphocytes, value of IgG and CD4/CD8 between the 2 groups before liver transplantation (P>0.05). But on 7 days and 14 days after liver transplantation, the levels of the total number of lymphocytes, value of IgG and CD4/CD8 in the observation group were superior to those of control group (P<0.05). Conclusion Perioperative nutritional support can improve the nutritional status and immune function in patients underwent liver transplantation.
ObjectiveTo study and compare the effects of inhaled preparations with open airway and conventional inhaled preparation on asthma patients.MethodsThe patients diagnosed with asthma and treated with the same inhaled preparation only who visited the outpatient department of West China Hospital of Sichuan University, were selected as the study subjects from April to September, 2019. The subjects were divided into the test group and the control group according to random ratio 1∶1. The conventional inhaled preparations were used in the control group. The inhaled preparations with open airway were used in the test group. Asthma control, life quality and treatment satisfaction rate were compared between the two groups after 3 months.ResultsA total of 150 subjects were included and one case dropped-off, then 149 effective subjects were obtained in which 75 cases in the test group and 74 cases in the control group. After 3 months’ treatment of inhaled preparations, the proportion of effective asthma control patients in the test group was higher than that in the control group, and the number of patients satisfied with the treatment of inhaled preparations was higher than that in the control group, with statistically significant differences (all P<0.05). The life quality of patients in both groups was improved compared with baseline, and the difference was statistically significant (P<0.05). However, the increase of scores in the test group was more than that in the control group, and the difference was also statistically significant (P<0.05). ConclusionInhaed preparations with open airway is superior to conventional inhaled preparation on asthma patients in asthma control, life quality and treatment satisfaction rate.
Objective To evaluate the effectiveness and safety of different injection sites for collagenase chemonucleolysis for lumbar intervertebral disc protrusion (LIDP). Methods We searched for randomized controlled trials (RCTs) and quasi-RCTs in the following electronic databases: Pubmed (1966 to May 2006), EMBASE(1966 to May 2006), The Cochrane library (Issue 2, 2006), CRD(Center for Reviews and Dissemination),York University, CBM (1978 to May 2006 ), CNKI(1994-2006)and VIP(1989-2006). Quality assessment and data extraction were conducted by two reviewers independently. Disagreement was resolved through discussion. Results Eight studies involving a total of 1035 participants met the inclusion criteria. Meta-analysis was not carried out because of apparent heterogeneity. Four studies made comparisons among intradisc, extradisc, and combined intra- and extra-disc injection. One study (62 participants) showed that intradisc injection was superior to extradisc injection (RR 3.71, 95% CI 1.19 to 11.58, Plt;0.05). Another study (240 participants) showed that intradisc injection was superior to combined intra- and extra-disc injection after 3 months and 6 months of follow-up (RR 0.88, 95% CI 0.80 to 0.98, Plt;0.05). The other two studies showed no significant difference among intradisc, extradisc, and combined intra- and extra-disc injection. Four studies (436 participants in total) showed that amongst three extradisc injections, both anterior epidural space injection and lateral epidural space injection were superior to posterior epidural space injection (Plt;0.05). Although one study indicated that anterior epidural space injection was superior to lateral epidural space injection (RR 1.24, 95% CI 1.03 to 1.51, Plt;0.05), no statistical significance was found between anterior epidural space injection and lateral epidural space injection in two other studies (Pgt;0.05). Conclusions There is insufficient evidence to identify which injection site for collagenase is the most effective for lumbar intervertebral disc protrusion. The included studies showed that both anterior and lateral epidural space injection were superior to posterior epidural space injection. However, these studies are too small and poor quality, and have different diagnostic criteria, follow-up time points, outcome measures and efficacy parameters. Thus, more high quality and large-scale RCTs are needed.
Objective To investigate the effects of 3 methods (suture removal, suture removal with epineurium neurolysis, and l igated femoral nerve resection with end-end suture) in repairing femoral nerve injury after l igation in different periods so as to provide a reference for cl inical use of repairing iatrogenic l igation injury of the peri pheral nerve. Methods A total of 120 adult female Sprague Dawley rats, weighing (200 ± 20) g, were used to prepare the animal models of left femoralnerve l igation, and were divided into groups A (n=40), B (n=40), and C (n=40) according different repairing methods. Atimmediate, 1, 3, and 5 months (10 rats each time point) after l igation, suture removal was performed in group A, suture removal with epineurium neurolysis in group B, and l igated femoral nerve resection with end-end suture in group C. At 3 months after operation, the foot-base angle (FBA) and the heels-tail angle (HTA), action potential and conduction velocity of femoral nerve, and wet weight of quadriceps femoris muscle (QFM) were measured; the samples of quadriceps femoris and femoral nerve were harvested for histological observation, muscle fiber count, and nerve fiber passing rate measuring. Results The FBA in group A was significant smaller than that in group C at immediate, 1, 3, and 5 months (P lt; 0.05), but there was no significant difference between groups A and B (P gt; 0.05). The HTA in group A was significantly smaller than that in group C at immediate, 1, 3, and 5 months (P lt; 0.05), and the THA in group B was significantly smaller than that in group C at 1, 3, and 5 months (P lt; 0.05). The wet weight of QFM in group B was significantly higher than that in group C at immediate, 3, and 5 months (P lt; 0.05), and the wet weight of QFM in group A was significantly higher than that in group C at immediate and 3 months (P lt; 0.05), but no significant difference was found between groups A and B at immediate, 1, and 3 months (P gt; 0.05). There was significant difference in the action potential of femoral nerve between group A and groups B and C at immediate and 1 month (P lt; 0.05), but there was no significant difference between other groups at 3 and 5 months (P gt; 0.05) except between groups A and C at 5 months (P lt; 0.05). The conduction velocity of femoral nerve in group A was significantly faster than that in group C at immediate, 1, and 5 months (P lt; 0.05), and it was significantly faster in group A than in group B at immediate and 1 month (P lt; 0.05), but no significant difference was found between groups A and B at 3 and 5 months (P gt; 0.05), between groups B and C at other time points (P gt; 0.05) except at immediate (P lt; 0.05). The count of muscle fibre of the quadriceps femoris was significantly more in groups A and B than in group C at immediate (P lt; 0.05); it was significantly more in group A than in group B at 5 months (P lt; 0.05). The passing rate of the femoral nerve fiber was significantly higher in group A than in groups B and C at 3 months (P lt; 0.05), but no significant difference was found between the other groups (P gt; 0.05). Conclusion After femoral nerve l igation, suture removal method has the best effect at early term, the next is epineurium neurolysis method, and the worst is the l igation femoral nerve resection with end-end suture repair.
ObjectiveTo evaluate the effectiveness of three-dimensional (3D) printing artificial vertebral body and interbody fusion Cage in anterior cervical disectomy and fusion (ACCF) combined with anterior cervical corpectomy and fusion (ACDF).MethodsThe clinical data of 29 patients with multilevel cervical spondylotic myelopathy who underwent ACCF combined with ACDF between May 2018 and December 2019 were retrospectively analyzed. Among them, 13 patients were treated with 3D printing artificial vertebral body and 3D printing Cage as 3D printing group and 16 patients with ordinary titanium mesh Cage (TMC) and Cage as TMC group. There was no significant difference in gender, age, surgical segment, Nurick grade, disease duration, and preoperative Japanese Orthopaedic Association (JOA) score, visual analogue scale (VAS) score, and Cobb angle of fusion segment between the two groups (P>0.05). The operation time, intraoperative blood loss, hospitalization stay, complications, and implant fusion at last follow-up were recorded and compared between the two groups; JOA score was used to evaluate neurological function before operation, immediately after operation, at 6 months after operation, and at last follow-up; VAS score was used to evaluate upper limb and neck pain. Cobb angle of fusion segment was measured and the difference between the last follow-up and the immediate after operation was calculated. The height of the anterior border (HAB) and the height of the posterior border (HPB) were measured immediately after operation, at 6 months after operation, and at last follow-up, and the subsidence of implant was calculated.ResultsThe operation time of 3D printing group was significantly less than that of TMC group (t=3.336, P=0.002); there was no significant difference in hospitalization stay and intraoperative blood loss between the two groups (P>0.05). All patients were followed up 12-19 months (mean, 16 months). There was no obvious complication in both groups. There were significant differences in JOA score, VAS score, and Cobb angle at each time point between the two groups (P<0.05). There was an interaction between time and group in the JOA score (F=3.705, P=0.025). With time, the increase in JOA score was different between the 3D printing group and the TMC group, and the increase in the 3D printing group was greater. There was no interaction between time and group in the VAS score (F=3.038, P=0.065), and there was no significant difference in the score at each time point between the two groups (F=0.173, P=0.681). The time of the Cobb angle interacted with the group (F=15.581, P=0.000). With time, the Cobb angle of the 3D printing group and the TMC group changed differently. Among them, the 3D printing group increased more and the TMC group decreased more. At last follow-up, there was no significant difference in the improvement rate of JOA score between the two groups (t=0.681, P=0.502), but the Cobb angle difference of the 3D printing group was significantly smaller than that of the TMC group (t=5.754, P=0.000). At last follow-up, the implant fusion rate of the 3D printing group and TMC group were 92.3% (12/13) and 87.5% (14/16), respectively, and the difference was not significant (P=1.000). The incidence of implant settlement in the 3D printing group and TMC group at 6 months after operation was 15.4% (2/13) and 18.8% (3/16), respectively, and at last follow-up were 30.8% (4/13) and 56.3% (9/16), respectively, the differences were not significant (P=1.000; P=0.264). The difference of HAB and the difference of HPB in the 3D printing group at 6 months after operation and last follow-up were significantly lower than those in the TMC group (P<0.05).ConclusionFor patients with multilevel cervical spondylotic myelopathy undergoing ACCF combined with ACDF, compared with TMC and Cage, 3D printing artificial vertebrae body and 3D printing Cage have the advantages of shorter operation time, better reduction of height loss of fusion vertebral body, and maintenance of cervical physiological curvature, the early effectiveness is better.
Objective To investigate short-term effectiveness of spinal navigation with the intra-operative three-dimensional (3D)-imaging modality in pedicle screw fixation for congenital scoliosis (CS). Methods Between July 2010 and December 2011, 26 patients with CS were treated. Of 26 patients, 13 patients underwent pedicle screw fixation using the spinal navigation with the intra-operative 3D-imaging modality (navigation group), while 13 patients underwent the conventional technique with C-arm X-ray machine (control group). There was no significant difference in gender, age, hemivertebra number and location, major curve Cobb angle, and Risser grade between 2 groups (P gt; 0.05). Operation time, operative blood loss, frequency of the screw re-insertion, and postoperative complication were observed. The pedicle screw position was assessed by CT postoperatively with the Richter’s standard and the correction of Cobb angle was assessed by X-ray films. Results All patients underwent the surgery successfully without major neurovascular complication. There was no significant difference in operation time, operative blood loss, and pedicle screw location between 2 groups (P gt; 0.05). A total of 58 screws were inserted in navigation group, and 3 screws (5.2%) were re-inserted. A total of 60 screws were inserted in control group, and 10 screws (16.7%) were re-inserted. There was significant difference in the rate of pedicle screw re-insertion between 2 groups (χ2=3.975, P=0.046). Patients of navigation group were followed up 6-24 months, and 6-23 months in control group. According to Richter’s standard, the results were excellent in 52 screws and good in 6 screws in navigation group; the results were excellent in 51 screws, good in 5 screws, and poor in 4 screws in control group. Significant difference was found in the pedicle screw position between 2 groups (Z= — 1.992, P=0.046). The major curve Cobb angle of 2 groups at 1 week and last follow-up were significantly improved when compared with preoperative value (P lt; 0.05), but there was no significant difference between 1 week and last follow-up (P gt; 0.05). No significant difference in correction rate of the major curve Cobb angle was found between 2 groups at last follow-up (t=0.055, P=0.957). Conclusion Spinal navigation with the intra-operative 3D-imaging modality can improve the accuracy of pedicle screw implantation in patients with CS, and effectually reduce the rate of screw re-insertion, and the short-term effectiveness is satisfactory.
