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 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.
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.
ObjectiveTo systematically evaluate the effectiveness of anterior versus posterior approaches with one-stage debridement and bone grafting for surgical treatment of spinal tuberculosis. MethodsDatabases including PubMed, MEDLINE, Ovid, Elsevier, CBM, WanFang Data, CNKI and VIP were electronically searched from 2004 to 2015 to collect relevant clinical studies about the effectiveness of anterior versus posterior approaches with one-stage debridement and bone grafting for surgical treatment of spinal tuberculosis. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies, and then meta-analysis was performed using RevMan 5.2 software. ResultsA total of 11 studies involving 1 063 patients were included. The results of meta-analysis showed that: correction of Cobb angle with the posterior approach was significantly larger than that of anterior approach (MD=-2.78, 95%CI -3.73 to -1.82, P<0.000 01); the allograft fusion time of anterior approach was shorter than that of posterior approach (MD=-0.21, 95%CI -0.35 to -0.08, P=0.002). But there were no significant differences between the two groups in operation time, intraoprative blood loss, loss of Cobb angle at final follow-up and time of total hospital stay (all P values >0.05). ConclusionPosterior approach can correct the Cobb angle significantly for the spinal tuberculosis patients with kyphosis, and anterior approach has a shorter allograft fusion time, but it is not able to correct the deformity of the patient to maintain the normal sequence of the spine. For the quantity and quality limitation of the included studies, this conclusion still needs to be proved by conducting more high quality studies.
ObjectiveTo explore the distribution and rule of pathogen strains in the third quarter and fourth quarter of 2012, and to provide the basis for clinical medication. MethodsTo retrospectively analyze the bacterial culture and drug susceptibility test results in the third quarter and the fourth quarter of 2012. ResultsThere were isolated 932 plants in the third quarter, and 915 plants isolated in the fourth quarter. Heavy drug resistance rates of detection of Pseudomonas aeruginosa decrease slightly. There was more multiple drug resistance of A. baumanii, Escherichia coli, Klebsiella pneumoniae, and methicillin-resistant Staphylococcus aureus in the fourth quarter than in the third one. ConclusionThe resistant strain increases in the fourth quarter. We should attach importance to the clinical examination, bacterial drug resistance monitoring, and rational use of antimicrobial agents.
Objective To analyze the expression of apoptosis-related genes of retinal blood vessel in early diabetic rats by gene chip technology. Methods To make diabetic rat model by intraperitoneal injection of streptozotocin (STZ). On the 6th week after blood pressure increased, 10 rats were executed in Diabetic group and normal control group respectively. 20 retinal blood vessels were extracted and the RNA was isolated. The probe was made of alpha;-32 P-deoxyadenosine triphosphate (dATP)-labeled sample which hybridized 1176 nylon chips, and then analyzed by software. Three different expression genes were selected to verify by reverse transcription polymerase chain reaction (RT-PCR). Results On the 6th week, 136 （11.5％） genes were differentially expressed ［up-regulated genes were 90(7.6%), down-regulated genes were 46(3.9%)］in diabetic group. These genes involved into different groups according to their function. Especially in 72 apoptosis-related genes, 15 genes were differentially expressed. The up-regulated genes were some TNF receptor family members such as TNFRSF12, TRAIL, TNFRSF9, FADD；Bcl-2 family members such as bcl-w, bax, bak1 and AKT. The down-regulated genes were FAF1 which related to fas. Conclusions The expression of retinal vascular gene in early diabetic rats has been changed complicatedly. In particular, the multiple apoptosis-related genes have been changed in early diabetic, and most of them are at the upstream of apoptosis pathway. These findings indicate that the development of diabetic retinopathy is associated with multiple signaling pathways leading to apoptosis, while the alterations on the level of molecular biochemistry are still limited in apoptosis induction period. （Chin J Ocul Fundus Dis，2008，24：244-248）
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 analyze the 2023 learning society construction project in order to provide references for researchers in this field. MethodsExcel 2021 software was used to summarize and comb the list of key tasks for the construction of a learning society in 2023 (field of higher continuing education) published on the official website of the Chinese Ministry of Education, and to visually analyze the research topics of key tasks in the medical field and the distribution of applicants. ResultsThe analysis found that a total of 250 projects were shortlisted in the cultivation and construction list, including 100 teaching reform and innovation tasks of continuing education for academic degrees, 100 reform and innovation tasks of non-academic education, and 50 tasks to explore the path of coordinated innovation of the three education. The project involved digital transformation, education and teaching reform, ideological and political education, etc. There were 17 medical projects, accounting for 6.8% of the total number of key tasks. The 17 medical key task declaration units were distributed in 12 provinces (regions), which were mainly concentrated in East China, and the construction of "non-double first-class" universities as the main force; The results mainly focused on personnel training and education and teaching reform. ConclusionThe analysis results of the key task list of 2023 learning society construction (field of higher continuing education) provide important references and enlightenment for the researchers in the field of education, and provide guidance and references for the future development of higher continuing education.
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.
Objective To study and analyze the related data to emergent public health events in 2008 Wenchuan Earthquake and two years before and after the earthquake, to examine the emergent health control system of Sichuan in terms of organization, implement, current status and problems, so as to offer first-hand data and decision-making references to the perfection of the monitoring system and raising the effect of control and prevention of the emergent public health envents effect. Methods The report data were statistically analyzed by Excel, EpiInfo software. Results Between 2006 and 2010, the emergent public health events in Sichuan had reduced gradually year by year, and a wave trough was formed in 2008 when Wenchuan Earthquake attacked; the emergent public health events in each year mainly took place in two peaks, one was from April to June and the other was from September to November. Compared with the period between 2006 and 2010, five among six heavily afflicted cities and prefectures with 18 heavily damaged counties in 2008 had dropped in the listing of emergent public health events. Between 2006 and 2010, the emergent public health events happening in schools of Sichuan accounted for 75.00%, especially the township primary schools were on the top of each index as place, cause, morbidity and mortality, but there were no serious emergent public health events. Among nine types of emergent public health events, the contagious disease events accounted for 79.30% while the food poisoning events accounted for 14.33%; and the contagious disease events mainly were respiratory tract infection diseases such as chicken pox, mumps and measles, and hepatitis A which were all preventable with vaccine, and accounted for 82.93%. Conclusion The construction of Sichuan’s health emergency system is a good foundation for the handling of emergent public health events. The emergent public health events in the whole province get gradually reduced year by year between 2006 and 2010, and all kinds of emergent public health events have been handled properly. With the national support for the disaster relief of Wenchuan Earthquake, the provincial emergent public health events after the quake in 2008 have scored the lowest level in the history without severe epidemics after the earthquake; and the plan of no severe epidemics within three years after the earthquake has come true with partner assistance in health system. By improving the control of contagious disease, food poison and preventable diseases, the incidence of emergent public health events can be dramatically reduced with lower morbidity and mortality. Only by means of multi-departmental cooperation and social participation for jointly preventing and controlling school emergent public health events, especially for preventing and controlling the contagious diseases in countryside and township primary schools, can all kinds of emergent public health events be timely prevented and controlled with decreased hazard.
