BACKGROUND: The incidence rate of spondylolysis of lumbar vertebral arch in recruits is higher during the training, and it affects the normal training. OBJECTIVE: To analyze the correlation of the incidence rate of spondy lolysis of lumbar vertebral arch with training and the original lesions at waist in recruits. DESIGN: A randomized sampling survey. SETTING: Department of Orthopaedics, the 97 Hospital of Chinese PLA. PARTICIPANTS: Totally 100 male recruits aged 18.7 years averagely en rolled in 2003 were involved in the survey. METHODS: The 100 recruits were followed up for the whole course, the X-ray examination at lumbar vertebrae of right, lateral and two-slope positions were observed before training and after 100-day reinforced training. MAIN OUTCOME MEASURES: The incidence rates of spondylolysis of vertebral arch, and whether there was slippage and other aggravations in those with spondylolysis before were mainly observed. RESULTS: All the 100 recruits entered the analysis of results. ① The in cidence rate of spondylolysis of vertebral arch before and after training: Be fore training, 5 cases had spondylolysis of L5 vertebral arch, and the incidence rate was 5%. At the end of the 100-day training, 8 cases had spondylolysis of lumbar vertebral arch, and the incidence rate increased to 8%. ② The results of X-ray examination before and after training: The Xray examination showed that isthmus narrowing of left and L5 vertebral arch occurred in 2 cases and 1 case respect ively, and spondylolysis of bilateral L5 vertebral arches occurred in 5 cases, including 1 case of degree I slip page before training. At the end of the 100-day training, the degree I slip page and below occurred in 3 of the 5 cases with spondylolysis of bilateral L5 vertebral arches before, another 3 cases with original narrowing of lumbar vertebral arch all had breakage. CONCLUSION: The incidence rate of spondylolysis of vertebral arch is associated with the training intensity. It suggestes that the examination of spinal cord should be reinforced in enrolled recruits, and the items of Xray examination at lumbar vertebrae of right, lateral and two-slope positions should be added.

The authors explained in the first place the challenges facing hospitals in the new century. These include: impact of the reform of the social security system on hospitals; impact of China's accession to the WTO on domestic hospitals; and impact of people's diversified needs on the construction of hospitals. Then the authors set forth some development strategies for hospitals in the new century. These include: ①establishment of new concepts; ②reinforcement of awareness in four aspects, viz. management awareness, competition awareness, service awareness, and innovation awareness; ③stress on the systematic nature of hospital construction, viz. market-and battlefield-oriented adjustment of the layout of disciplines, construction of the contingent of talents in accordance with the needs of the market, and enhancement of medical quality in light of new quality concepts; ④establishment of a flexible and highly efficient management mechanism, viz. setting up a speedy and highly efficient decision-making procedure and an individual-centered management mechanism, reforming the distribution mechanism in line with the rules of the market economy, and finding ways for the government to solve the problem of funds compensation for non-profit hospitals.

Anemia is commonly observed in lung cancer patients,and it is mainly caused by chemotherapy.Anemia can cause several debilitating symptoms such as fatigue and tachycardia which will not only influence the patients' quality of life and therapy effect,but also short the survival time.So anemia has been regarded as a poor independent prognostic indicator of the disease.Transfusion the erythrocytes and using the erythropoiesis stimulating agents is the main treatments of the disease.Using the erythropoiesis stimulating agents is the main treatment before the hemoglobin decreasing significantly in order to reduce the times of transfusion.Keeping the hemoglobin between 10.0-12.0 g/dl can improve the patients' quality of life and avoid the adverse events such as thrombus formation at the same time.

Objective Through observing the changes of serum creatinine (Scr),blood urea nitrogen (BUN),and Cystatin C (Cys C) to prove whether the treatment of patients of diabetic nephropathy (DN) in V period with Jiawei-qidan-tangshen decoction is really effective.Methods 60 patients of DN in V period were randomly divided into a treatment group and a control group by random number table method,with 30 patients in each group.Glycated hemoglobin (HbA1c),serum creatinine (Scr),blood urea nitrogen (BUN),and Cystatin C (Cys C) were detected before and after the treatment.Results 12 weeks after treatment,Scr,Cys C (19.19±37.06) μmol/L,(1.81 ±0.69)mg/L had significantly declined in the treatment group (P＜0.001),and had no significant change (147.25±62.70)μmol/L,(2.04± 1.20)mg/L in the control group (P＞0.05).Total effective rate of Scr and Cys C was 73.33％ and 83.33％ in the treatment group and 40％ and 53.33％ in the control group respectively,both showing significant difference (P＜0.05).Conclusion It is effective to treat patients of DN in V period with,Jiawei-qidan-tangshen decoction,and have no obvious side effects.

Objective:To observe the changes of cognition and gait dysfunction in postnatal rats with cerebral palsy and the possible mechanism.Method:An improved Philips method was used and the model of cerebral palsy was induced.Fifty four Wistar rats aged 14 d with cerebral palsy were randomly divided into 3 groups,cerebral palsy control group(CM,n=18),VB6 treated group(CM+VB6,n=18)and sham surgery group(CS).Morris water maze test(MWMT)was used to detect the change of cognition func-tion including the escape latency(EL)and swimming distance(SD).Footprint pattern test(FPT)was used to detect the changes of gaits inctuding the left/right stride length(LSL,RSL),front-base width(FBW),hind-base width(HBW),distance from left/right front footprint/hind footprint overlap(DLFHFO,DRFHFO).Results:MWMT:EL and SD of CM+VB6 were shorter than CM's from D 12(P 0.05).FPT:LSL and RSL were longer from D 5,and HBW and DRFHFO were shorter from D 7compared with those in CM+VB6 and CM group(P
