Objective To provide references for the rational allocation of health personnel in rural hospitals through understanding the status of health human resources of rural hospitals in remote and poor areas of Sichuan Province. Methodes This study used cluster sampling method, combined with questionnaire survey and qualitative interviews. A total of 711 health workers of 29 rural hospitals in Pengzhou and Baoxing of Sichuan Province were interviewed. SPSS16.0 was used for descriptive analysis.Results The average age of rural hospitals health personnel in remote and poor areas of Sichuan Province was 30 years old. Post-secondary education accounted for 58.12%, and Bachelor degree or above accounted for 7.2%. The number of medium and senior professional titles account for 8.4 %. The ratio of doctors to nurses was 1:0.55. In the survey of health workers, those doctors with practice (assistant) license accounted for 38.5%, and those without any qualification occupied 27.1 %. Conclusions The professional titles of medical personnel of rural hospitals in remote and poor areas in Sichuan province are generally low. The distribution of professional categories is irrational. The staff in charge of prevention and care are inadequate. There exist a large number of unqualified medical workers. Therefore, the government should increase the investment in rural health and take measures to stabilize the team structure, introduce the talented, and strengthen the training for health personnel of rural hospitals to improve their overall quality.
Objective Secondary osteoporosis is very common in patients with primary osteoporosis. Diabetes is a known cause of secondary osteoporosis. While type I diabetes has been clearly linked with diabetic osteoporosis, the effect of type II diabetes on bone health is controversial.Methods In the present study, we investigated the associations between type II diabetes and osteoporosis as well as fractures at different skeletal sites in Women’s Health Initiative participants.Results Common risk factors such as age, race, BMI, HRT use, and the history of fractures were significantly associated with osteoporosis and fractures in this study population. Diabetic women appeared to have a decreased risk of osteoporosis although it no longer remained significant after adjusting for other risk factors (crude HR=0.78, 95%CI 0.61 to 0.99; adjusted HR=0.93, 95%CI 0.73 to 1.19). The impact of diabetes on fractures varied at different body sites. There was a significant increase of risk of hip fracture (HR=2.54, 95%CI 1.14 to 5.66), but not spine fracture (HR=1.71, 95%CI 0.81 to 3.60) and arm fracture (HR=0.92, 95%CI 0.48 to 1.76) among the women with diabetes. Although the overall risk of fractures in diabetic women did not differ significantly from non-diabetic women (HR=1.37, 95%CI 0.89 to 2.09), the difference had a two-fold increase and was statistically significant after 2,000 days (HR=2.01, 95%CI 1.21 to 3.35), indicating a different hazard at different stages of diabetes.Conclusion Our findings suggest that type II diabetes may not be clearly associated with osteoporosis, it increases a site-specific fracture risk at least in the hip. In addition, the overall fracture risk appears to increase in a time-dependent manner.
ObjectiveTo systematically review the efficacy and safety of chemo-radiotherapy combined with hyperthermia (HCRT) for rectal cancer, and to provide evidence for clinical practice. MethodsWe searched the Cochrane Library (Issue 6, 2014), PubMed, EMbase, Web of Science, CBM, CNKI, VIP and WanFang Data databases from inception to July 2014. All relevant randomized controlled trials (RCTs) of HCRT for rectal cancer were collected. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then meta-analysis was performed using RevMan 5.3 software. ResultsA total of 9 RCTs involving 663 patients were included. The results of meta-analysis showed that:Compared with the chemo-radiotherapy (CRT) group, the HCRT group were significant superior in complete response (OR=3.74, 95%CI 2.14 to 6.53), total effective rate (OR=4.23, 95%CI 2.69 to 6.66), 3-year survival rate (OR=4.48, 95%CI 1.81 to 11.06) and recurrence rate (OR=0.19, 95%CI 0.09 to 0.42). ②Compared with the radiotherapy (RT) group, the HCRT group was associated with significant improvement in complete response rate (OR=3.01, 95%CI 1.24 to 7.29). ConclusionCurrent evidence shows, HCRT is superior to CRT or RT in the treatment of rectal cancer. However, due to the limited quantity and quality of the included studies, more high quality studies are needed to verify the above conclusion.
Objective To explore the correlation of risk factors affecting the L2-4BMD level in patients with post-menopausal osteoporosis. Methods Ninety-two patients with post-menopausal osteoporosis were surveyed with a retrospective questionnaire. We used the findings to set up a multiple stepwise regression model and perform correlation analysis with L2-4BMD levels as the dependent variable and risk factors as the independent variables. Results Assuming that age has a definite effect on the L2-4BMD level of menopausal women, menopausal age limit, history of milk drinking, menopausal age, menarche age, fracture history and bend-back entered into the multiple stepwise regression equation. Conclusions Menopausal age limit, history of milk drinking, menopausal age, menarche age, fracture history, and bend-back influence patients with menopausal osteoporosis.The menopausal age limit is especially important. Awareness of the risk factors of osteoporosis should be raised.
【Abstract】 Objective To explore the reasons of tendon adhesions post tendon allograft. Methods From May1990 to June 2000, 85 cases receiving tendon allograft were given tenolysis because of tendon adhesions. There were 76 males and 9 females, with an average age of 24.5 years (8-46 years). Injury was caused by machine in 38 cases, electric in 32 cases, cut in 4 cases, explosion in 4 cases and extremity mutilation in 7 cases; including 66 cases of flexor tendon deficit and 19 cases of extensor tendon deficit. Six cases had 1 tendon deficit, 79 cases had tendon deficit of more than 2. The defect region ranged from I to V. The total mobil ity of the joint was less than 220° in 73 cases. The impairment of skin, bone, nerve and vascular were treated before tendon allograft. Results Because TAM was less than 50% of TPM, the patients were given tenolysis 4-15 months after operation. And the mobil ization began at the first day after operation to improve the range of active movement. Patients were followed up 7-17 years (mean 12.7 years). TAM and TPM were in accord. Mean total mobil ity of joint was200°. Conclusion The serious of primary hurt is the important factors of tendon adhesion. Improvement of tendon selected, treatment and early mobil ization can rel ieve the tendon adhesion.
Objective To systematically evaluate the efficacy and safety of iris-registration in wavefront-guided LASIK (IR+WG LASIK) versus conventional LASIK for correction of myopia accompanied with astigmatism. Methods Such databases as PubMed, EMbase, The Cochrane library (Issue 2, 2012), CBM, CNKI, VIP, and WangFang Data were searched to collect the randomized controlled trials (RCTs) and quasi-RCTs about IR+WG LASIK versus conventional LASIK for correction of myopia accompanied with astigmatism. The retrieval time was from inception to February 2012, and the language was in both Chinese and English. Two reviewers independently screened the literature, extracted the data and assessed the quality of the included studies. Then the meta-analysis was performed by using RevMan 5.1 software. Results A total of 9 studies involving 3 903 eyes were included. The results of meta-analysis showed that, compared with the conventional LASIK group, the IR+WG LASIK group had a higher ratio in patients with postoperative uncorrected visual acuity no less than 1.0 (RR=1.03, 95%CI 1.01 to 1.05, P=0.002), as well as in patients with best-corrected visual acuity gained over 1 line (RR=1.75, 95%CI 1.49 to 2.16, Plt;0.000 01); it was smaller in the postoperative high order aberration RMS (WMD=−0.16, 95%CI −0.21 to −0.11, Plt;0.000 01), coma-like RMS (WMD=−0.05, 95%CI −0.11 to 0.00, P=0.07), spherical-like RMS (WMD=−0.15, 95%CI −0.23 to −0.07, P=0.000 2), and residual astigmatism (WMD=0.14, 95%CI 0.10 to 0.18, Plt;0.000 01); moreover, it was lower in the incidence of postoperative glare (RR=0.27, 95%CI 0.15 to 0.50, Plt;0.000 1), and it was higher in the subjective satisfaction of patients (RR=1.08, 95%CI 1.04 to 1.13, P=0.000 3). Conclusion Compared with conventional LASIK, IR+WG LASIK can more effectively reduce astigmatism, postoperative high order aberration RMS and spherical-like RMS. It can also get visual function including uncorrected visual acuity and best-corrected visual acuity, consequently increase patient’s satisfaction. But further studies are still required for its long-term effect.
Objective To conduct bibliometric analysis of systematic review and meta-analysis published in the Chinese Journal of Evidence-based Medicine. Methods Based on the Chinese academic periodical network as a data pool, literature on systematic reviews (involving meta-analysis) and clinical decision-making researches were retrieved in the Chinese Evidence-Based Medicine Magazine from 2001 to 2010, screened and categorized by the medical and hygienic standards of Chinese Library Classification (fourth edition), and then were counted and sorted. Results There were 425 articles about systematic reviews (involving meta-analyses) and clinical decision-making studies in the Chinese Evidence-Based Medicine Magazine, with an yearly increasing number. Basically, those articles involved all subjects such as clinical medicine, preclinical medicine, hygenics, pharmacy, and traditional Chinese medicine. Conclusion Development levels of evidence-based research in medical subjects are different, each of which has its own feature. Also, some systematic reviews do not strictly follow the Cochrane Handbook. Therefore, high-quality systematic review is still needed in each subject.
ObjectiveTo explore the family function on patients with depression and its influential factors, in order to provide a basis for family support treatment for the patients. MethodsA total of 122 depressed patients from Mental Health Center of West China Hospital between February 2012 and June 2013, and one of their family members were chosen to be the study subjects. Another 122 non-clinical controls and one of their family members were recruited from a community near Sichuan University were regarded as the controls. All the subjects were asked to finish the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), the Multidimensional Scale of Perceived Social Support (MSPSS), and the Family Assessment Device (FAD). Additionally, the patients received a diagnostic interview to provide the features of their depression. ResultsThe general average score of Q-LES-Q in families with depressed patients was significantly lower than that in the control families (t=-6.243, P<0.01). The general average score of each dimension in FAD for families with depressed patients was significantly higher than that for control families (t=3.644, 3.872, 2.694, 3.369, 5.369, 4.941, 5.241; P<0.01). According to FAD health division scoring, the unhealthy proportion in terms of communication, emotional reaction, emotional link, behavioral control and general function for families with depressed patients was significantly higher than that for control families (χ2=6.778, 23.698, 26.580, 39.875, 17.123, 10.712; P<0.05). The Q-LES-Q scores and the five FAD dimensional scores (except role and affective involvement) were negatively correlated (r=-0.388, -0.188, -0.200, -0.276, -0.370; P<0.05). The scores of perceived social support for families with depressed patients had significant positive correlations with the scores of all FAD dimensions except affective involvement (r=0.363, 0.345, 0.244, 0.418, 0.328, 0.457; P<0.05). The risk factors for unhealthy family function included: female (OR=1.141, P<0.05), poor education (OR=0.948, P<0.01), first-episode (OR=1.416, P<0.05), suicidal attempt (OR=1.014, P<0.05), incomplete suicide (OR=1.367, P<0.01) and depression episode number (OR=1.035, P<0.05). ConclusionDepression is associated with impaired family function in Chinese families. Female, poor education, first episode of depression, suicidal attempt, incomplete suicide and depression episode number are the influential factors for family function on patients with depression.
Objective To study some related factors of effect on gluteus muscle contraction and provide the therapeutic basis. Methods The curative effect was assessed in 154 patients who were classified by age, patient’s condition, orthopedic degree in operation and rehabilitation with an average follow-up period of 25 months(ranging from 5 to 36 months).Results The excellent rate of 18-24 years old (25/30) was lower than that of 5 -17 years old(120/124) (Plt;0.05); the excellent rate of slight patients was higher (107/109) than that of serious patients (38/45) (Plt;0.01); the excellent rate from higher orthopedic degree was higher(111/113) than that from lower orthopedic degree(34/41) (Plt;0.01); and the excellent rate of rehabilitation was much higher (107/110) than that of general treatment (38/44) （Plt;0.05）. Conclusion Age, patient’s condition, orthopedic degree in operation and rehabilitation are important factors to affect the curative effect on gluteu muscle contraction.
Objective To analyze retrospectively the 1861 wounded inpatients and deaths in West China Hospital of Sichuan University after the Wenchuan earthquake, so as to provide reference for the improvement of emergency plans for the disaster of earthquake and the establishment of state-level regional medical centers. Methods The analysis was based on the data provided by the Department of Information of the Hospital up until July 23. The software of Microsoft EXCEL was used for data input, and SPSS 11.5 was used for statistical analysis. Results Up to July 23, 2728 cases from the disaster area have been treated in the hospital, of whom 872 were admitted into the emergency department and 1856 into the inpatient department (974 men, median age 43 years; 882 women, median age 46 years). Most patients were sent to the hospital within the first 2 weeks after the quake (82.4%), and the number of inpatients reached its peak on Day 8 after the quake (976 cases). The majority of the inpatients were discharged on Day 9 to Day 18 after the quake (60.2%). The wounded were mainly from Deyang, Aba Prefecture and Dujiangyan. The admission diagnoses were mainly fracture (54.84%), craniocerebral injury (9.81%) and thoracoabdominal injury (7.54%). There were totally 33 deaths, including 5 pre-hospital deaths, 1 emergency death and 27 inpatient deaths. Conclusion The development of an emergency plan for the medical rescue after an earthquake disaster is an essential step to enhance the emergent response capability, improve the scientific process of field triage, transport and transfer, and ensure the rational allocation and application of healthcare resources after any unexpected big disasters in the future.
