CONCLUSION: It is an effective method to vitrectomy combined with inferior scleral buckling for the special kind of retinal detachment which has following features:1) the course was more than 6mo;2) there were at least one hole located in the 5:00-7:00 of the marginal retina;3 ) the detachment range of retina more than 270 degrees and retinal proliferation of cable in retinal detachment.

In August 2001, Chinese military released the "Diagnostic criteria, principles of principles of prophylaxis and treatment of military training injuries" for implementation in the armed forces for the first time in history. The "Criteria" standardizes the definitions of military training injuries, categorizes the various injuries with specific diagnostic criteria, and specifies the principles of their prevention and treatment. This paper gives a brief account of the main contents of the "Criteria", and reiterates the basis of designation of precuresor symptoms of various injuries which occur during military training. The paper points out that the army officers should revise the training plan in regard to its contents, duration and intensity timely, if the additive ratio of limb pain and joint swelling reaches 20% and 10%, respectively, during the 3rd-4th training week. During the period of implementation, the "Criteria" has shown to be practical and easy to operate. It has not only provided standardized technical bases for the case reports, stastistics, clinical investigations, and popularization of technics, but also provided a reliable and comparable theoretical foundation to the officers to formulate training protocols. Furthermore, because of the application of the principles of prevention and treatment of injuries during training as documented in the text, as well as psychological education has been emphasized, the incidence of military training injury has been lowered markedly. Through epidemiological study in 10 different army groups, it has been shown that the yearly add up ratios have been lowered from 30%-45% to below 10%.

Objective To explore the clinical value of urethral dilation in treatment of female bladder outlet obstruction. Methods Thirty-five female bladder outlet obstruction patients were selected, and all the patients failed for more than 1 month inαreceptor blocker treatment. The patients underwent urethral dilation under local anaesthesia, once a week, for a total of 12 times. The international prostate symptom score (IPSS), quality of life score (QOL) and residual urine volume before and after treatment were examined. Results The IPSS, QOL and residual urine volume after treatment were significantly lower than those before treatment: (10.23 ± 6.31) scores vs. (21.41 ± 3.71) scores, (2.31 ± 0.65) scores vs. (5.43 ± 0.60) scores and (20.73 ± 10.59) ml vs. (85.23 ± 12.15) ml, and there were statistical differences (P<0.01). Conclusions The urethral dilation is one of the effective treatments for female bladder outlet obstruction patients who fail in αreceptor blocker treatment. It can make a part of patients avoid invasive examination and surgery, and it is worth to be popularized in clinic and primary hospital.

Objective To investigate whether systemic inflammatory response syndrome(SIRS) after cerebral infarction is associated with poor outcome and its associated clinical factors.Methods We prospectively studied 500 patients with cerebral infarction.recorded the associated clinical factors on presentation and calculated the mortality at 21 st day.Results There are 85 SIRS patients in 500 patients with cerebral infarction,31 with total anterior cerebral infarction(TACI),34 with partial anterior cerebral infarction(PACI),15 with posterior cerebral infarction(POCI)and 5 with lacunar cerebral infarction (LACI).The frequency of SIRS was positively correlated with mortality rate according to Oxfordshire Commanity Stroke Project(OCSP)subtypes in cerebral infarction patients with fever(Spearman correlation coefficient=1.0:P＜0.001).Single factor analysis showed that the risk factors for both SIRS and mortality of cerebral infarction were as follows:age,infection,48h Chinese Stroke Scale score,48h Glassgow score,OCSP subtypes and dysphagia.Diabetes Was the risk factor for SIRS.but had no effect on mortality.On Cox regression,48h Glassgow score was the sole independent risk factor of outcome.However.if SIRS was included in the formula.P＞0.05.ConclusionsSIRS is the predictor of poor outcome after acute cerebral infarction.It is important to prevent SIRS especially in TACI and POCI.Diabetes is the risk factor for SIBS.but has no effect on mortality.

Abstact:Aim To identify whether the petroleum e-ther fraction of Yueju pill (YJ-PE)could exhibit a po-tent rapid antidepressant effect and to investigate the underlying biological mechanism involved.Methods Fourty-four male KM mice were randomly assigned to five groups:the control group (saline group),low dosage of YJ-PE,middle dosage of YJ-PE,high dos-age of YJ-PE and ketamine.After a single drug admin-istration,we used tail suspension test (TST)to test the rapid antidepressant effect of YJ-PE in KMmice at 30 min.Another twenty-four male KM mice were ass-inged to three groups:control group,screened effective low dosage of YJ-PE group and ketamine group.We usd TST to assess these mice at 24 h post a single ad-
ministration.Western blot was performed to examine the expression of BDNF and TrkB in hippocampus of KMmice at 30 min and 24 h post a single administra-tion.Results An acute administration of YJ-PE de-creased the immobility time of KMmice in TST and in-creased the expression of BDNF and TrkB as soon as 30min post a single administration and lasted at least for 24 hours.Conclusion YJ-PE (low dosage)ex-hibits a rapid antidepressant-like potent,and the po-tent rapid antidepressant effects of YJ-PE are associat-ed with the up-regulation of BDNF and TrkB.

Objective To investigate the tissue distribution character of cinobufagin in in vivo in rats,in order to provide some references for rational drug use in the clinic.Methods Two kinds of solutions of cinobufagin were given to rats(0.5 and 1 mg/kg) by sublingual iv injection.The cinobufagin concentration in rat tissues corresponding to different time-point was determinated by HPLC.The biological samples of the different tissuses were performed by liquid-liquid extraction method.Results Cinobufagin distributed rapidly to tissue after sublingual iv injection.At 30 min cinobufagin in eight tissues except fat was detected.At 60 min the concentration in a majority of tissue achieved the peak value and liver′s was tiptop.When the concentration of cinobufagin increased by gemination,the time of reaching peak value had no change.Only the concentration of cinobufagin increased slightly corresponding to the time-point.Conclusion The distribution of cinobufagin in tissues of rats is extensive.Both the absorption and elimination of cinbufagin are quick and up to the top concentration in brain tissue.

In light of modern management theories and the actual situation in the hospital, a post and performance based hospital compensation system was designed. The chief features of the design include: ① Compensation consists mainly of post salary and performance salary while giving expression to the principle of stability and gradual transition, with the fixed part (accounting for about 60%) of the original file salary being retained; ②Post salaries fall under a hospital wide unified grade compensation framework, with grade evaluations based on a hospital wide unified system of indexes and weight, and they go up or down within the salary width each year according to the results of performance assessment; ③ Performance salaries are closely linked with post grades and performance assessment, with a hospital wide unified model of post and performance contracts being the basis for assessment; ④ The entire compensation design is based on scientific and standard post surveys, post appraisals and post specifications.

To study the effect of cholesterol and 25-OH-cholesterol on cholesterol metabolism in HepG2 cells and the effect of coptisine (Cop) extracted from Coptidis Rhizoma (CR) in reducing and regulating cholesterol. In this study, TC, TG, LDL-c and HDL-c were measured by biochemical analysis; mRNA and protein expressions of LDLR, HMGCR and CYP7A1 were detected by qRT-PCR and Western blot. According to the results, cholesterol and 25-OH-cholesterol inducing could decrease in mRNA and protein expressions of LDLR and CYP7A1, so as to increase TC and LDL-c contents. However, Cop could up-regulate mRNA and protein expressions of LDLR and CYP7A1 and down-regulate that of HMGCR, so as to reduce TC and LDL-c levels. These findings suggested that Cop has potential pharmacological activity for reducing cholesterol, and may reduce cholesterol by regulating mRNA and protein expressions of key genes involved in cholesterol metabolism, such as LDLR, CYP7A1 and HMGCR. This study laid a firm theoretical foundation for developing new natural drugs with the cholesterol-lowering activity.
