OBJECTIVETo explore therapeutic effects of Modified pinning combined with external tension band for the treatment of Gartland type III humeral supracondylar fractures in children.

METHODSFrom February 2009 to November 2010, 79 children with Gartland type III humeral supracondylar fractures were treated by modified pinning (pinning cross internal and external condyle assisted with lateral condyle) combined with external tension band (crossing needle end and hooking around) through lateral approach of elbow. There were 47 males and 32 females, with an average age of 8.7 years (ranging from 2.5 to 14 years). The time from injury to operation was 2 h to 8 d. The elbow joint function and Carrying angle were observed before and after treatment. The Flynn criteria were used to evaluate therapeutic effects.

RESULTSSixty-one patients were followed up (18 patients' data were lost) for 6-30 months (mean 13.5 months). According to Flynn criteria, 53 patients got excellent result, 7 good and 1 fair.

CONCLUSIONTreatment of child Gartland type III humeral supracondylar fractures with modified pinning combined with external tension band through lateral approach of elbow is believed to be an ideal method, which has advantages of reliable fixation, rapid recovery and less complications.

Objective To explore the effects of benzirnidazole on spermatogenesis function and enzymatic activity in testis of male rats.Methods 40 male Wistar rats,clean degree,were randomly divided into four groups,10 in each.The rats in the low- dose group (20 mg/kg),the moderate-dose group (100 mg/kg) and the high-dose (200 mg/kg) were treated with benzimidazole at different doses by garage,once a day for 80 consecutive days.Simultaneously,the rats control group were treated with the equivalent volume of distilled water and tween-80.In the end of the experiment,the rats were weighed,the testis and epididymides were immediately excised and weighed,the appearance was observed,and the viscera coefficients of the bilateral testis and epididymides were calculated.The number and motility of sperms in the tail of epididymis,the activity of some enzymes (LDH, ACP,SDH,G-6-PDH) of testis were tested.Results The testis and epididymides in the control group and the low-dose group were pink,large,smooth and plump,but they were mauve,small,obviously atrophic in the moderate-dose group and the high-dose group. The viscera coefficient of the testis and epididymides,the number and motility of sperms in the tail of epididymis were significantly decreased in the moderate-dose group and the high-dose group (P

OBJECTIVETo construct an operable strategic framework for cholera prevention and control which mobilized the advantages of local resources and adapted to social developments in Chengdu, and to evaluate its application effects.

METHODS(1) After analyzing the local epidemic data of cholera in Chengdu from 1994 to 2004, we determined the main problems of cholera prevention and control works as well as the efficiency and deficiency of employed measures, and then formed a basic strategic framework. (2) After 55 invited experts preliminarily scored the strategic framework, we selected 72 specific measures to establish a measure entry database, and then the importance and operability of each measure were scored by 17 core experts. (3) Finally, the effectiveness of this strategic framework was evaluated according to the analyzing results of infection control, health education and etiological monitoring.

RESULTS(1) The framework took government leadership as main scenario and the informatization as subordination scenario. Meanwhile, it focused on three points: the improvement of social environment, the completion of system and mechanisms for monitoring and early warning, and the enhancement of CDC response to public health emergencies. Total importance score and operability score of 35 specific measures included in this framework was 4.20 ± 0.86 and 4.09 ± 0.87, respectively. (2) Chengdu had maintained zero cholera incidence for five consecutive years from 2005 to 2009 since it gradually began to implement the strategic framework in 2002. There were 19 positive cholera cases detected by etiological monitoring and all of them were seafood or fishery products including soft-shelled turtles, silver carps and bullfrogs. The coverage rate and qualification rate of the training for grassroots cadres, grassroots medical workers, mobile cooks and their assistants was 98.14% (198 452/202 220) and 98.17% (194 820/198 452) in average, respectively. The qualification rate of the training for employees in food industry was over 96.00% (912 470/950 489). The average awareness rate of cholera prevention and cure knowledge in rural residents, grassroots cadres, grassroots medical workers, mobile cooks and their assistants was 93.87% (1653/1761) and the average formation rate of good hygiene habits was 70.58% (1243/1761).

CONCLUSIONA strategic framework suitable for cholera prevention and control in Chengdu has been successfully established in this study. The incidence rate of cholera has maintained zero in Chengdu for five consecutive years under incessant threatening conditions such as the occurrence of cholera cases from time to time in its surrounding areas and the continuous existence of Bacillus comma in seafood or fishery products that entered local markets. Therefore, it demonstrated a good application effects.

OBJECTIVETo investigate the effect of Radix Paeoniae Rubra (RPR) on the expression of heme oxygenase (HO-1) and induced nitric oxide synthase (iNOS) in endotoxin-induced acute lung injury in rats and its protective mechanism.

METHODSForty Wistar rats were divided randomly into 5 groups with 8 rats in each group: saline control group (NS group), lipopolysaccharide group (LPS group), RPR-treatment group, RPR-prevention group and Hemin group. The effect of RPR on protein content, the ratio of neutrophiles in bronchoalveolar lavage fluid, malondialdehyde (MDA) content in the lung and the activity of serum NO were observed. Arterial blood was drawn for blood-gas analysis. The expression of HO-1 and iNOS in lung tissues was detected by immunohistochemistry and morphometry computer image analysis. The histological changes of the lung were observed under light microscope.

RESULTSCompared with that in NS group, the expression of HO-1 and iNOS was markedly increased in LPS group (P<0.01). In RPR-treatment, RPR-prevention, and Hemin groups, the expression of iNOS was significantly lower, while the expression of HO-1 was higher than that in LPS group (P<0.05). The protein content, the ratio of neutrophiles in bronchoalveolar lavage fluid, the content of MDA and the activity of serum NO in LPS group were significantly higher than those in NS group (P<0.01). There was a significant decrease in the level of arterial bicarbonate and partial pressure of oxygen in the LPS group (P<0.01); these parameters of lung injury however, were significantly lower in RPR-treatment, RPR-prevention, and Hemin groups than LPS group (P<0.05 or P<0.01). The pathologic changes of lung tissues were substantially attenuated in RPR-treatment, RPR-prevention, and Hemin groups than LPS group.

CONCLUSIONSThe high expression of HO-1 reflects an important protective function of the body during lipopolysaccharide-induced acute lung injury. The protective effect of RPR on lipopolysaccharide-induced acute lung injury is related to the inhibition of iNOS expression and the induction of HO-1 expression.

OBJECTIVETo investigate the effects of α3 neuronal nicotinic acetylcholine receptor (nAChR) on apoptosis and p38 signal transduction pathway in SH-SY5Y cells and to assess the roles of α3 nAChR in the pathogenesis of Alzheimer's disease (AD).

METHODSThe levels of α3 nAChR mRNA and protein were measured by real-time PCR and Western blot, respectively, in SH-SY5Y cells transfected with α3 nAChR siRNA. The mRNA level of bcl-2 and bax was measured by the real-time PCR. The siRNA transfected SH-SY5Y cells and control were then treated with 10 µmol/L Aβ25-35 for another 48 h, and the change in apoptotic rate and the levels of p-p38 and p38 were measured by flow cytometry and Western blot. Subsequently these SH-SY5Y cells were exposed to a blocker of p38 protein, and the apoptotic rate was measured again.

RESULTSCompared to the controls, the expression of α3 nAChR at mRNA and protein levels in the SH-SY5Y cells transfected with α3 nAChR siRNA decreased by 95% and 86%, respectively; the mRNA levels of bax increased 2.11 times and that for bcl-2 decreased 0.53 times. The apoptotic rate was unaffected (3.40% ± 0.20%); but it increased after Aβ25-35 treatment (24.52% ± 1.59%); the level of p-p38 protein also increased by 178% in the α3 nAChR inhibited cells treated with Aβ25-35. Compared to controls, the Aβ25-35-treated SH-SY5Y cells and the Aβ25-35-treated and siRNA-transfected cells both showed a reduction in apoptosis after treatment with p38 blocker, especially in the former.

CONCLUSIONThe siRNA silencing of α3 nAChR mRNA may enhance the effect of Aβ25-35 on the cell apoptosis by increasing the levels of p38 protein and bax mRNA and decreasing the level of bcl-2 mRNA, which may play a role in the pathogenesis of AD.
