ObjectiveTo explore effect of preoperative prognostic nutritional index (PNI) on clinically related postoperative pancreatic fistula (CR-POPF) after distal pancreatectomy (DP) and analyze its influencing factors in order to provide a basis for clinical prediction of CR-POPF. MethodsThe clinicopathologic data of patients who successfully completed DP in the Affiliated Hospital of Xuzhou Medical University and met the inclusion and exclusion criteria of this study from January 1, 2017 to January 31, 2021 were collected retrospectively. The preoperative PNI value was calculated and the optimal cut-off value was obtained according to the receiver operative characteristic (ROC) curve. The patients were divided into low and high PNI based on the optimal cut-off value. The clinicopathologic characteristics were compared between the patients with low and high PNI and CR-POPF or not. At the same time, multivariate logistic regression was used to analyze the influencing factors of CR-POPF. ResultsA total of 143 patients who met the inclusion and exclusion criteria were included in this study. The CR-POPF occurred in 33 cases (23.08%) after DP, and the average preoperative PNI was 52.26 (39.20–65.10), the optimal cut-off value of PNI was 50.55, with 49 cases in the low PNI group and 94 cases in the high PNI group. In patient with low PNI, the proportions of patients aged ≥65 years and with CR-POPF were higher than those with high PNI (P<0.05). In the patients with CR-POPF, the proportions of patients with soft pancreatic texture and with low preoperative PIN were higher than those without CR-POPF (P<0.05). Further, the multivariate logistic regression showed that the the preoperative low PNI (OR=5.417, P<0.001) and soft pancreatic texture (OR=4.126, P=0.002) increased the risk of CR-POPF. ConclusionLow preoperative PNI and soft pancreatic texture increase risk of CR-POPF after DP, and it is necessary to preoperatively evaluate PNI status of patients.
Objective To evaluate the results of operative treatment of complex acetabular fractures and to investigate its influence factors. Methods From June 2000 to August 2006, 54 patients with complex acetabular fractures were treated, including 44 males and 10 females aged 20-75 years old (average 39.1 years old). Fractures were due to traffic accidentin 40 cases, fall ing from high places in 8 cases and crush by heavy objects in 6 cases. All cases were fresh and close fractures and the time from injury to operation was 5-72 days. There were 5 cases of posterior column and posterior wall fracture, 25 of transverse and posterior wall fracture, 2 of T-type fracture, and 22 of double column fracture. During operation, Kocker- Lagenbach approach was used in 23 cases, anterior il ioinguinal approach was appl ied for 3 cases and the combination of anterior and posterior approaches was performed on 28 cases. AO reconstructive plate and screw internal fixation were used in all the cases. Results Fifty-two cases were followed up for 12-74 months (average 31.3 months). Anatomical reduction was achieved in 23 cases, satisfactory reduction in 19 cases, poor reduction in 10 cases, and the excellent and good rate reached 80.77%. During operation, 1 case suffered from a tear in the external il iac vein and healed after vein repair; 2 cases had sciatic nerve injury and took mecobalamin as oral administration, one of them fully recovered, and the other had incomplete recovery at 18-month follow-up. At the final follow-up, there were 6 cases of severe heterotopic ossification, one of them received heterotopic bone resection and the rest 5 patients received conservative treatment; there were 9 cases of traumatic osteoarthritis, one of them received total hip replacement and the rest 8 patients received conservative treatment; there were 5 cases of avascular necrosis of the femoral head, two of them received total hip replacement, 1 received no further treatment because the femoral head didn’ t collapse, and the rest 2 patients gave up total hip replacement; 75.00% patients were graded as excellent and good according to the modified Merled’Aubigné-Postel hip score system. Patients’ qual ity of l ife was compared with local population normsmatched for age and sex by using SF-36 scales, their overall score were below the local population norms, and their general health, vital ity, role l imitation due to emotional problems and mental health were comparable to the local population norms. Logistic regression analysis revealed the time to reduce hip dislocation, qual ity of fracture reduction nd traumatic arthritis were independent risk factors affecting postoperative functional outcomes. Conclusion Applying open reduction and internal fixation in the treatment of displaced complex acetabular fractures has a satisfying therapeutic effect. Time to reduce hip dislocation, qual ity of fracture reduction as well as traumatic arthritis are independent risk factors affecting postoperative functional outcomes.

ObjectiveTo explore the related factors of postoperative survival of patient with gastric cancer, so as to provide the corresponding evidence support for the prognosis evaluation.MethodsThe clinicopathologic data of patients with gastric cancer who underwent surgical treatment in the Fourth Affiliated Hospital of Baotou Medical College and the Fourth Hospital of Baotou City from January 2006 to December 2009 were retrospectively collected. The influences of clinicopathologic data (gender, age, tumor size, tumor location, lymph node metastasis, tumor thrombus, tumor differentiation, TNM stage, operation mode, and postoperative chemotherapy) on postoperative survival of patients with gastric cancer were analyzed. Univariate analysis was used to analyze the influencing factors of postoperative survival in the patients with gastric cancer and Cox proportional hazards regression was used to analyze the independent risk factors.ResultsA total of 80 patients with gastric cancer were included in this study. Up to December 31, 2014, the median survival time at 50% cumulative survival rate was 95 months. Univariate analysis showed that the survival of patients with gastric cancer was related to tumor size, lymph node metastasis, tumor differentiation, and TNM stage (P<0.05). Further multivariate analysis showed that later TNM stage was an independent risk factor for affecting postoperative survival of patients with gastric cancer (P<0.05).ConclusionPostoperative survival of patients with gastric cancer is related to tumor size, lymph node metastasis, tumor differentiation, and TNM stage; And later TNM stage is an independent risk factor for affecting survival of patients with gastric cancer.
ObjectiveTo evaluate the reporting quality of systematic reviews (SRs)/meta-analyses on acupuncture focusing on literature screening results and explore the influencing factors of the complete reporting.MethodsPubMed, EMbase, CNKI, WanFang Data, and VIP databases were searched to collect SRs/meta-analyses on acupuncture from inception to December 31st, 2019. Two reviewers independently screened literature, extracted data and evaluated the reporting quality of literature screening results of SRs/meta-analyses on acupuncture based on PRISMA statement. Logistic regression model analysis was applied to explore the influencing factors of the complete reporting rate of literature screening results. Statistical analysis was performed by using Excel 2016 and SPSS 16.0 software.ResultsA total of 1 227 SRs/meta-analyses were included. Only 62.3% SRs fully reported the four parts of literature screening results. The parts with a low reporting rate included the number of studies assessed for eligibility (73.2%) and the reasons for exclusions at each stage (67.0%). And the reporting rate of the literature screening flowchart was also low (63.6%). The reporting rate of literature screening results in Chinese SRs was lower than that in English SRs, and there was significantly statistical difference (P<0.001). Multivariate logistic regression analysis showed that the type of published journal, publication year, pages of article and the number of searched databases were correlated with the complete reporting rate of literature screening results (P<0.001).ConclusionsThe complete reporting rate of the literature screening results of SRs on acupuncture is low, especially in Chinese SRs. The complete reporting rate of literature screening results is significantly higher for SRs published after PRISMA statement, in SCI journals, with longer length and more searched databases.
Objective To investigate the factors that affect platelet-rich plasma (PRP) in promoting bone regeneration and repairing. Methods Recent l iterature was reviewed, concerning the preparations of PRP, physiological mechanism and the latest appl ications in orthopedic field. Results PRP, the concentrated body of autologous platelet, was rich in platelets and was the source of autologous growth factors. Many studies had shown that PRP played an important role in promoting bone regeneration and repairing. However, a few experimental results contradicted this point. The reason might be that the biological properties of PRP were influenced by various factors, such as workmanship, vector, activation schemes, working concentration, individual difference. Conclusion The concentration and qual ity of platelet and other related factorsof PRP affect the rel iabil ity of the results and conclusions. So an efficient and stable production method of PRP should beestabl ished.
ObjectiveTo compare the complications and clinical scores of posterior lumbar intervertebral fusion (PLIF) in middle-aged and older patients of different ages, and to assess the risk of complications of PLIF in different ages, providing a reference for clinical treatment.MethodsThe clinical data of 1 136 patients, who were more than 55 years old and underwent PLIF between June 2013 and June 2016, were retrospectively analyzed. According to the age of patients undergoing surgery, they were divided into 3 groups as 55-64 years old, 65-74 years old, and ≥75 years old. The general characteristics, comorbidities, and surgical data of the three groups were compared, with comparison the morbidity of complications. According to the minimal clinical important difference (MCID), the improvement of patient’s pain visual analogue scale (VAS) score and the Oswestry disability index (ODI) score were compared. Univariate logistic regression analysis was used to analyze the difference of complications and the improvement of VAS and ODI scores. Multivariate logistic regression analysis was performed for the risk factors of complications.ResultsThere were significant differences in the number of surgical fusion segments and osteoporosis between groups (P<0.05); there was no significant difference in gender, body mass index, operation time, preoperative American Society of Anesthesiologists (ASA) classification, and comorbidities between groups (P>0.05). All patients were followed up 6-62 months with an average of 27.4 months. Among the results of postoperative complications, there were significant differences in the total incidence of intraoperative complications, systemic complications, minor complications, and the percentage of improvement of ODI score to MCID between groups (P<0.05); but there was no significant difference in the total incidence of complications at the end of long-term follow-up and the percentage of improvement of VAS score to MCID between groups (P>0.05). Univariate logistic regression analysis showed that after adjusting the confounding factors, there were significant differences in intraoperative complications and the percentage of improvement of ODI score to MCID between 55-64 and 65-74 years old groups (P<0.05); systemic complications, minor complications, complications at the end of long-term follow-up, and the percentage of improvement of ODI score to MCID in ≥75 years old group were significantly different from those in the other two groups (P<0.05). Multivariate logistic regression analysis showed that age was a risk factor for systemic complications, minor complications, and complications at the end of long-term follow-up. Except for age, long operation time was a risk factor for intraoperative complications, increased number of fusion segments was a risk factor for systemic complications, the number of comorbidities was a risk factor for minor complications, and osteoporosis was a risk factor for complications at the end of long-term follow-up.ConclusionThe risk of surgical complications is higher in the elderly patients (≥75 years) with lumbar degenerative diseases than in the middle-aged and older patients (<75 years), while the improvements of postoperative VAS and ODI scores were similar. Under the premise of fully assessing surgical indications, PLIF has a positive effect on improving the elderly patients’ quality of life.
