Objective To discuss the feasibility,indications,surgical techniques,and outcome con- cerning the application of less invasive stabilization system (LISS) for complex proximal femoral fractures.Methods We treated 12 complex proximal femoral fractures using femoral LISS reversely from June 2005 to May 2006. They were five complex intertrochanteric fractures and seven subtrochanteric ones.By AO classification,two were type 31-A2.2,two type 31-A2.3,one type 31-A3.3,one type 32-A3.1,three type 32-B1.1,one type 32-B2.1, and two type 32-B3.I.The patients were treated with closed or indirect reduction and fixation with percutaneous LISS plate reversely.Results There were no major postoperative complications in this study.The mean operation time was 65 minutes (range,50 to 90 minutes),the mean intra-operative blood loss was 142 milliliters (range,50 to 400 milliliters),and the mean postoperative hospital stay was 9.3 days (range,6 to 15 days).All patients had a clinical follow-up;the mean follow-up time was 7.2 months (range,3 to 14 months).Ten cases healed clinically three months postoperatively,one periprosthetic fracture healed four months and one pathological fracture healed six months after operation.At the final radiographic follow-up,no collapse,varus deformity,cutting-out,hardware failure,or avascular necrosis was found.Conclusions Femoral LISS used reversely can provide secure fixation for proximal femoral fractures biomechanically and anatomically.It is also easy and safe.It is particularly suitable for old patients with intertrochanteric fractures complicated with disorders of internal organs and severe osteoporosis or patients with complex proximal femoral fractures.It is important to be skillful in indirect reduction and positioning of guide wire into hole A,and to avoid immediate weight-bearing postoperatively.

Objective The aim of this paper is to know about the pollution of microcystin-LR(MC-LR)in Fenhe First reservoir and Fenhe Second reservoir in Taiyuan and provide reference for making the policy of prevention microcystin-LR pollution.Methods During the low water period(May,2005)and common period(Oct,2005),5 liter water was sampled in the entrance,the center and the exit in Fenhe First reservoir and Fenhe Second reservoir respectively.The concentrations of MC-LR in two reservoirs were determined by the high-performance liquid chromatography(HPLC).Results The average concentration (0.875 ?g/L)of MC-LR in low water period was 3 time of that(0.283 ?g/L)in common period in Fenhe First reservoir.The average concentration(0.815 ?g/L)of MC-LR in low water period was 17 time of that(0.048 ?g/L)in common period in Fenhe Second reservoir.The level of MC-LR in the entrance was the highest,that in the exit was the lowest,that in the center was middle. The concentration of MC-LR of the entrance in low water period was more than the MC-LR limit(1 ?g/L)in Life drinking water hygienic guide(2001).Conclusion MC-LR pollution has been found in Fenhe First reservoir and Fenhe Second reservoir and the pollution is serious in low water period.

Objective To explore the effects of selenium enriched Spirulina platensis(Se-SP) on(antioxidation) and regeneration of rat hepatocytes after partial hepatectomy.Methods Sixty-seven percent(hepatectomy) was performed in rats after high dose(H) and low dose(L) Se-SP was given via gastric tube for 7 days.Then selenium(Se),glutathione peroxidase(GPx),superoxide dismutase(SOD) and(malondiaoldehyde)(MDA) in hepatocytes were determined.The results were compared with normal saline(giving) via gastric tube before hepatectomy(C) and sham operation(S) groups.Hepatocytes were obtained(before) operation and 24h after operation,and the expression index of proliferating cell nuclear antigen((PCNA)) in hepatocytes was detected by immunohistochemistry,and the DNA damage of hepatocytes induced by peroxide was analyzed by comet assay.Results After partial hepatectomy,Se content,GPx and SOD(activity),and PCNA expression index were obviously higher(P

Objective:To explore the clinical effect of multidisciplinary cooperation model in the prevention of acquired dysphagia in ICU.Methods:A multidisciplinary team was set up to collect 118 patients in Neurosurgery ICU of our hospital as the research object. The patients were divided into the experimental group and the control group, 59 cases in each group. The control group implemented the routine nursing measures of ICU, and the experimental group implemented the multidisciplinary cooperative nursing mode. The incidence of ICU acquired swallowing disorders (ICU-ASD) and complications of the two groups were compared.Results:There was no significant difference between the two groups in the incidence of swallowing dysfunction 24 hours after tracheal extubation ( P>0.05). The incidence of swallowing dysfunction 48 hours and 72 hours after tracheal extubation in the control group was 11.86% (7/59) and 16.95% (10/59) respectively, while the test group was 1.69% (1/59) and 3.39% (2/59) respectively. The difference was statistically significant ( χ 2values were 4.827 to 7.230, P< 0.05 or 0.01); the incidence of aspiration, aspiration pneumonia and malnutrition in the control group were 11.86% (7/59), 10.17% (6/59) and 8.47% (5/59), respectively, while the test group were 1.69% (1/59), 0 and 0, respectively, with statistically significant difference ( χ 2value was 4.827, P< 0.05). Conclusion:Multidisciplinary cooperation model can effectively prevent the incidence of ICU-ASD, and ultimately reduce the incidence of complications.

Objective To investigate the correlation between the plasma unconjugated bilirubin(UCB)and electrical activity of brain in term neonates with hyperbilirubinemia,and explore the parameters that possess the prognostic value and deduce a series of discriminant for prognostic judgment.Methods Thirty-two neonates with hyperbilirubinemia and 31 neonates without hyperbilirubinema(control group)were studied with standard EEG,and they were assessed for their neurological development in 3 and 6 months.A statistical method of Bayes Discriminant analysis was adopted to set up an equation with values of parameters of EEG,clinic datum and consequence.Stepdic and Dis-grim processes were used to pick out the parameters which had great significance for predicting the outcome of nervous system development.A series of discriminant was deduced for prognostic judgment and then cross validation was performed to assess the accuracy of the discriminant.Results 1.The standard EEG and brain electrical activity map records indicated that the hyperbilirubinemia group had longer maximum duration of interburst interval(IBI),longer mean duration of IBI,lower amplitude under all conditions,more anterior dysrhythmia(AD)in wake,and higher incidence of sleep-wake cycle disturbance.2.The plasma concentration of UCB was linear correlated with AD in wake.3.Gestational age,birth weight,plasma concentration of UCB,burst duration of IBI in trace alternate,amplitude in all sleep state,AD in wake,brief burst not in quiet sleep and sleep-wake cycle disturbance might play important roles in predicting the outcome of neonates with hyperbilirubinemia.Conclusions Cerebral electrical activity is an effective tool for predicting neurologic outcome of neonates with hyperbi-lirubinemia.Cerebral electrical activity and clinic data will provide a new method for accurately predicting neurological development and prognosis.

To evaluate the effect of Hexue mingmu tablets on traumatic hyphema caused by blunt ocular trauma.
●METHODS: Totally 150 patients of traumatic hyphema were divided into seven types by using ultrasound biomicroscopy combining with anterior segment abnormalities, each type was randomly classified as trial group and control group. The trial group was administered Hexue mingmu tablets, control group was treated by hemocoagulase.
●RESULTS: The absorbing time of trial group was shorter than that of the control group. And there was statistical significance between the two groups (P<0. 05).
● CONCLUSlON: Hexue mingmu tablets is an effective medicine to treat traumatic hyphema. Ultrasound biomicroscopy can be used as a routine examination method in traumatic hyphema.
