ObjectiveTo summarize the relationship between lateral femoral notch sign (LFNS) and anterior cruciate ligament (ACL) rupture. MethodsThe relevant literature of LFNS at home and abroad in recent years was retrospectively reviewed, and its mechanism, diagnostic criteria and influencing factors in diagnosis of ACL rupture were summarized and analyzed.ResultsThe LFNS is associated with rotational stability of the knee. As an indirect sign of ACL rupture, the LFNS has high clinical diagnostic value, especially the diagnosis of ACL rupture with lateral meniscus injury.ConclusionThe diagnostic criteria and influencing factors of LFNS in diagnosis of ACL rupture are still unclear and controversial, which needs further study.

An increasing number of health system researchers use systematic review to synthesize research evidence to inform the development of health policies at global and national levels. However, there are methodological challenges facing the health system research in undertaking systematic reviews of health policy literatures. This paper explored the constraints and promise of systematic review as a tool for evidence-based health system research in developing countries. It introduced the systematic review method and its evolution in health research over the past decades. The paper then discussed the definition of health system research, as system science, and contrasted its features/characteristics to those of medical research. It discussed and analyzed if the systematic review could be an effective tool for evidence-based health system research, particularly in developing countries. The paper concludes that the systematic review may be a very useful tool that can be used for evidence-based health system research to address specific policy issues; however, research on some health system/policy issues may not be appropriate to use the systematic review at all.
Using 70 SD white rats, diveded in two groups at random, after the common carotid artery wa(?) exposed, anastomosis of the artery was done by whole-layer suture and suture without including the endothelial layer, respectively. The rate of patency of both groups immediately after operation was 100 percent, where as in late stage, 94 percent and 97 percent, respectively. From the histologic exam ination, it was found that in the group of whole-layer suture, the time required to cover the sutureline with endothelium was delayed and there was rupture of the clastic fibers.
ObjectiveTo identify the risk factors of Intensive Care Unit (ICU) nosocomial infection in ICU ward in a first-class hospital in Wuxi, and discuss the effective control measures, in order to provide evidence for making strategies in preventing and controlling nosocomial infection.
MethodsAccording to the principle of random sampling and with the use of case-control study, a sample of 100 nosocomial infection patients were selected randomly from January 2012 to December 2014 as survey group, and another 100 patients without nosocomial infection as control group. The data were input using EpiData 2.0, and SPSS 13.0 was used for statistical analysis; t-test and χ2 test were conducted, and the risk factors were analyzed using multi-variate logistic regression model. The significant level of P-value was 0.05.
ResultsBased on the results of univariate analysis, there were 13 risk factors for ICU nosocomial infection, including diabetes mellitus, hypoproteinemia, being bedridden, surgical operation, immunosuppression, glucocorticoids, organ transplantation, tracheal intubation, length of hospitalization, length of mechanical ventilation, length of central venous catheter, length of urinary catheter, and length of nasogastric tube indwelling. Multi-variate logistic analysis indicated that hospitalization of 7 days or longer[OR=1.106, 95%CI (1.025, 1.096), P=0.001], diabetes mellitus[OR=2.770, 95%CI (1.068, 7.186), P=0.036], surgical operation[OR=7.524, 95%CI (2.352, 24.063), P=0.001], mechanical ventilation of 7 days or longer[OR=1.222, 95%CI (1.116, 1.339), P<0.001], and nasogastric tube indwelling of 7 days or longer[OR=1.110, 95%CI (1.035, 1.190), P=0.003] were considered as independent risk factors for ICU nosocomial infection.
ConclusionHospitalization of 7 days or longer, diabetes mellitus, surgical operation, tracheal intubation of 7 days or longer, and gastric intubation of 7 days or longer are the major risk factors for nosocomial infection in ICU ward. Advanced intervention and comprehensive prevention measures are helpful to reduce the nosocomial infection rate and ensure the safety of medical treatment.
OBJECTlVE:To investigate Ihe changes of macuiar lesions in dry type of age re[amd maeuJar clegcneration(AMD)and search for a sensitive melhod for detecting tile development of the disease. METHODS:The fundus fluoreseein angiography(FFA) ,visual acuity,FM 100-hue test and photopie electroretinogram(ERG)were used to examine a series of 60
patients(111 eyes)with dry AMD aged 50~80 years with the visual acuity of le;1.0.The patients were felhwed tip in 3~74 months(average 30.2 months). RESULTS:In 68 eyes undergone FFA examination and followed llp for Ihe average period of 25.6 months ,the macular lesions were found worsened in 25%, The visual acuity in follow-up periods was found decreasing more than 2 lines in 18% of the fotal 111 affectd eyes.There were not any statistically significat difference in photopic ERG between the initial and final cxaminations in 63 eyes tested. The tolal error score of FM 100-hue test had a statistically
significant difference between the initial test and the test taken two years afterwards(Plt; 0.01 )in 81 eyes examlnccl. CONCLUSIONS:Most of the macular lesions and visual acuity in dry type of AMD revealed a [avorahle prognosis,but occasionally complicated with ehoroidal neovaseularization. The total error score of FM 100-hue test might be a sensitive method for monitoring the development of dry type of AMD. （Chin J Ocul Fundus Dis,1997,13: 150-152）

ObjectiveTo explore the research hotspots of thyroid cancer nursing, and provide reference and guidance for future research on thyroid cancer nursing. MethodRelevant literature on thyroid cancer care was retrieved through the China National Knowledge Infrastructure (CNKI) and Web of Science (WOS) Core Database, and then analyzed the data using CiteSpace 6.2R4 software. ResultsThis study included a total of 1 096 Chinese literature and 263 English literature. The total number of publications was on the rise. The top 10 keywords in CNKI were: surgery, anxiety and depression, perioperative care, quality of life, complications, postoperative care, clinical pathway, rapid recovery surgery, differentiated thyroid cancer, and psychological care. Except for rapid recovery surgery, the centrality of other key words was greater than 0.1. The top 10 keywords in WOS were: quality of life, management, 131I, papillary thyroid cancer, surgery, impact, anxiety, prevalence, risk factor, and differentiated thyroid cancer. Among them, quality of life played an important intermediary role in co-occurrence networks, with the highest centrality of 0.34. ConclusionsQuality of life, mental health, perioperative period, and papillary thyroid cancer are research hotspots in thyroid cancer care both domestically and internationally. The management of quality of life and symptom management are the development trend of future research. Further research on thyroid cancer care needs to be strengthened, and important measures should be taken to address clinical issues and promote the recovery of thyroid cancer patients. We should strengthen domestic multi center cooperation, expand the breadth and depth of research, and promote the prosperous development of thyroid cancer nursing.
Objective
To systematically review the association between prenatal exposure to dichlorodiphenyltrichloroethane (DDT) or polychlorinated biphenyls (PCBs) and the risk of congenital anomalies.
Methods
PubMed, EMbase, WanFang Data, VIP and CNKI databases were electronically searched to collect case-control studies on the relationship between prenatal exposure to DDT or PCBs and congenital anomalies from inception to February 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using Stata 13.0 software.
Results
A total of 14 studies involving 2 238 infants with defect and 2 335 infants without defect were included. The results of meta-analysis showed that: the prenatal exposure to high level of DDT increased the incidence of cryptorchidism (OR=1.12, 95% CI 1.09 to 1.15, P<0.001). However, DDT exposure had no correlation to hypospadias and neural tube defects. The associations between prenatal exposure to PCBs and cryptorchidism, hypospadias, neural tube defects were not discovered.
Conclusion
Prenatal exposure to high levels of DDT may be a risk factor for cryptorchidism. Due to limited quality and quantity of the included studies, more high-quality studies are needed to verify above conclusion.
