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: To explore an ideal method and evaluate its clinical outcome in treating bronchostenosis induced by esophagus cancer. Methods: All cases were given argon plasma coagulation therapy to widen their trachea and shrink the focus area in terms of the invasion site and severity of trachea. Then some of them were placed with membrane-covered trachea brackets or given photodynamic therapy. Finally all the patients received bronchial artery embolizing chemotherapy to enhance the therapeutic efficacy. Results: Among the 23 cases treated with argon plasma coagulation (APC) therapy, 4 patients who did not receive any other treatment died within 58 days. The six patients who were placed trachea brackets only lived a period of 98 days on average. Seven patients who were placed trachea brackets and given bronchial artery embolizing chemotherapy lived a period of 166 days on average. Among the rest 6 cases who were cured with photodynamic therapy plus bronchial artery embolizing chemotherapy, 2 suffered from trachea-esophagus fistula 1-2 month later after leaving hospital and membrane-covered trachea brackets had to be rearranged. One died of severe emptysis 126 d later. The patients were followed up until November 30, 2007. The survival period in 2 cases was over 180 d, in 2 cases over 220 days, and in 1 case over 240 d. The mean survival time was 198 d during follow-up period. Conclusion: The combined multifold sequential therapy guided by endoscope is an ideal method to cure bronchostenosis induced by esophagus cancer. It is worthy of further studying and publicizing.

Objective To detect levels of serum platelet activating factor(PAF),thrombomodulin(TM) and white blood cell(WBC),platelet count(PLT) in neonates with meconium aspiration syndrome(MAS),and observe changes of mediators of inflammation and function of endotheliocute.Methods All cases were taken vein blood in 24 h and 72-96 h after birth.Surm PAF and TM were detected by EILSA technique,at the same time,blood cell counts were determined.Results PAF and WBC in neonates with MAS increased,which were relevant to the patients′ condition.TM of neonates with MAS increased significantly,especially in 72-96 h after birth and(aggrava)-ted with the patients′ condition.Conclusion Neonates with MAS have inflammatory reaction and injured endotheliocyte,which are(inte)-raction.

Objective To observe changes of luteinizing hormone (LH), follicle-stimulating hormone (FSH) and testosterone (T) in umbilical vein blood between male and female neonates, and assess the effect of serum LH, FSH and T on fetal growth.Methods Umbilical vein blood was obtained from 130 neonates (64 females and 66 males) in the second hospital of changshu city. According to birth weight, 130 neonates were divided into 3 groups: macrosomia (n=28), intrauterine growth restriction (IUGR) (n=31) and normal neonates (n=71). The serum levels of LH, FSH and T were measured by radioimmunoassay.Results 1.The levels of LH, FSH and T in umbilical vein blood were significantly higher in male neonates than those in females (P

Objective:To determine if suitable electric pulses-mediated DNA and DNA and bupivacaine complexes delivery technologies could enhance effects of botulinum neurotoxin serotype A (BoNT/A) DNA vaccines in mouse model. Methods:Vaccination of mice i.m. with plasmid DNA replicon vaccine pSCARSHc and conventional plasmid DNA vaccine pcDNASHc following electric pulses and with DNA and bupivacaine complexes. AHc-specific group antibody ELISA titers and lymphocyte proliferative responses of mice were detected and IgG1 and IgG2a isotype profiles were assayed. Results:Immune effects of DNA vaccines were enhanced following electric pulses and bupivacaine delivery. Effects of DNA vaccines following electric pulses were better than that of DNA vaccines formulated with bupivacaine,and the combined delivery technology of electric pulses and bupivacaine induced the highest level of specific antibodies and lymphocyte proliferative responses. Plasmid DNA replicon vaccine pSCARSHc induced relatively higher AHc-specific antibodies and lymphocyte proliferative responses in immunized Balb/c mice than conventional plasmid DNA vaccine pcDNASHc in these DNA delivery technologies. And vaccine pSCARSHc induced Th2/Th1-type immune responses with a general bias to Th2-type,and vaccine pcDNASHc induced Th2-type immune responses. Conclusion:Suitable electric pulses-mediated DNA and DNA and bupivacaine complexes delivery technologies could enhance effects of BoNT/A DNA vaccines in mouse model. Therefore,the methods described here potentially provide suitable strategies in developing an efficacious vaccine against botulinum neurotoxin serotype A.

The average life expectancy in Macau is ranking the second in the world, the consumption of fresh medicinal plants is a profound culture in Macau. The paper focus on the distribution of the antioxidant herbs, a comprehensive investigation and analysis the amount of the plant resources was carried out. The antioxidant activity of alcohol extracts was determined by using the DPPH method, and six kinds fresh herbs with high antioxidant free radical activity were screened out. Reference to adult daily dose of vitamin C, it is calculated that the daily dose amount of fresh herbs is less than 200 g. For the expected shortage of resources and the ecological status of Macau, we give some suggestions of herbal introduction in population ecology reconstruction.
