Objective To explore the relationship between the body mass index and health-related quality of life(HRQoL) of young students aged 18～25 years old. Methods 4696 students aged 18～25 years old from nine provinces and municipalities (Jiangsu, Anhui, Gansu, Qinghai, Fujian, Boijing, Jilin, Jiangxi and He'nan) were investigated. The HRQoL of students with different body mass index were compared with rank sum test and lo-gistic regression analysis. Results Obesity and underweight students scored lower in both physical component and mental component scores of SF-36. Compared to students with normal weight, odds ratios (ORs) of impaired HRQoL among obesity students significantly increased in both physical domain (OR=1.86) and mental domain (OR=1.90), while OR of impaired HRQoL among underweight students significantly increased only in physical domain(OR=1.21). Analysis for boys and girls scparately,OR of impaired HRQoL increased in physical domain among underweight boys(OR=1.37), and increased in mental domain among overweight girls(OR=3.85). Con-clnsion Different body mass index have different impact on young students' HRQoL. Both obesity and trader-weight could reduce HRQoL. But obesity have more impact on girls' mental domain than boys, and underweight have more impact on boys' physical domain than girls.

Aim To investigate the changes of Na~+,K~+-ATPase activity and ? isoforms in rat neurons suffered from global ischemia.Methods The BCAL rat was induced by bilateral carotid artery ligation.The contents of H_2O,Na~+ and K~+ in brain tissue were detected.The method of spectrophotometry was applied to measure the activities of Na~+,K~+-ATPase.With immunohistochemical assay,the expression of the Na~+,K~+-ATPase ?_1,?_2,or ?_3 isoform was detected in neurons of rat hippocampus and cortex following ischemia.Results In the BCAL rats,the contents of H_2O and Na~+ were increased while the content of K~+ and the activity of Na~+,K~+-ATPase were decreased.The ?_1,?_2 or ?_3 isoform of Na~+,K~+-ATPase distributed in a tissue-specific fashion in neurons of hippocampus and cortex,in which ?_1 and ?_3 were abundant and ?_3 was more than ?_1,but ?_2 was much less.In BCAL rat,?_1 and ?_3 isoforms were significantly decreased in hippocampus and cortex neurons.Conclusion These results suggest that the changes of Na~+,K~+-ATPase ?_1 and ?_3 isoforms may be involved in the global cerebral ischemia

Objective To analyse the personality characteristics of medical undergraduate and graduate newcomers. Methods Cattell 16 Personality Factor Questionnaires (16PF) were employed to assess the personality of 675 undergraduate newcomers (306 males and 369 females) and 155 graduate newcomers (76 males and 79 females),and the results were compared with the established findings of the country. Results Compared with male undergraduate newcomers,the scores of rule-consciousness,self-reliance and environmental adaptation of male graduate newcomers were higher,while those of sensitivity,openness to change,tension,cowardice and bravery were lower (P

OBJECTIVETo evaluate the clinical results of the medial patellofemoral ligament (MPFL) reconstruction combined with the lateral retinacular release for the treatment of recurrent patellar dislocation.

METHODSFrom March 2011 to June 2013, 15 patients with recurrent patellar dislocation underwent arthroscopic MPFL reconstruction combined with the lateral retinacular release. The graft was autogenous semitendinosus and semimembranosus tendon. There were 5 males and 10 females with an average age of 19.4 years old (ranged,14 to 32 years old). The patients suffered recurrent patellar dislocation at least twice preoperatively. Preoperative conventional X-ray, CT, and MR examination were used to analyze the causes of the patellofemoral joint and MPFL injury. Preoperative Lysholm score was 69.85 ± 11.52. During operation, the arthroscopic examination was performed to evaluate the patellofemoral alignment and patellar tracking.

RESULTSAll the patients were followed up for an average of 27.6 months (ranged,12 to 36 months) with no recurrent dislocation and sub-dislocation. All the patients showed negative apprehension test at straight and 30 ° flexions of knee. The range of motion of knee returned to normal level at 12 months after operation. There were no patients with subjective discomfort of knee. Postoperative Lysholm score was improved to 92.60 ± 5.75.

CONCLUSIONThe technique of arthroscopic MPFL reconstruction combined with the lateral retinacular release is an effective surgical procedure for the treatment of recurrent patellar dislocation, which can relieve the symptom of knee and improve the patella stability and knee function.

Objective To understand the endemic characteristics and regularity of cystic echinococcosis by evaluating and classifying its endemic situation in Non Tibetan Plateau regions,so as to provide the evidence for formulating effective preventive and control measures. Methods The prevalence data of cystic echinococcosis in 174 counties(cities,districts,banners)in Non Tibetan Plateau regions from a national survey were collected and analyzed by the sample cluster method in 2012. Results The 174 counties(cities,districts,banners)could be classified into 4 clusters by spatial distribution. The first cluster with human high prevalence rate,low infection rate of livestock,and positive rate of dog stool antigen included 3 counties. The second cluster with high infection rate of livestock,low prevalence rate of human,and positive rate of dog stool antigen included 20 counties(cit-ies). The third cluster with high positive rate of dog stool antigen,low prevalence rate of human,and low infection rate of livestock included 39 counties(cities,districts,banners). The fourth cluster with low rates of the above 3 indices included the rest 112 counties. Conclusions The results of the cluster analysis conform to the current epidemiological status of cystic echinococcosis in the Non Tibetan Plateau regions. The epidemiological characteristics and geographical distributions of the four area types will pro-vide a basis for the classified management and guidance of cystic echinococcosis control in these areas.

Objective:Comparing the effect of different doses of simvastatin in lowering the serum lipid.Methods:79 patients were randomized into group A and group B,and were given simvastatin 10 mg*d-1 (group A) and 20 mg*d-1 (group B),respectively for a total of 8 weeks.Results:Comparing with baseline,in group A,TC,TG,LDL-C were decreased by 23.4%,20.0% and 30.7%,respectively (P＜0.01); HDL-C was increased by 17.5%.The content of serum TC,TG and LDL-C was decreased to the normal range in 12.8%,28.2% and 15.4% of the patients in group A.For the group B,TC,TG,LDL-C were decreased by 32.7%,22.8% and 42.8%,respectively (P＜0.01); HDL-C was increased by 13.7%.The content of serum TC,TG and LDL-C was decreased to the normal range in 65.0%,57.5% and 65.0% of the group B patients.Conclusion:Oral intake of 20 mg of simvastatin once a day can effectively reduce the serum lipid.The patients can well tolerate and no obvious side effect was observed in our study.

Objective To investiGate the distribution of clinical infectious pathoGens and druG resistance status of common bacteria in the Ninth Peopleˊs Hospital Affiliated to medicine School of ShanGhai Jiao TonG University in 20l2. Methods Clinical isolated bacterial strains were collected from the Ninth Peopleˊs Hospital Affiliated to medicine School of ShanGhai Jiao TonG University durinG 20l2. The identification of bacteria and antimicrobial susceptibility were determined by VITEK 2 COMPACT automatic microbioloGy analyzer. The data were analyzed by WHONET 5. 4 software. Results A total of 3456 pathoGenic strains were collected. Of them,Gram positive cocci,Gram neGative bacilli and funGus accounted for 20. 3%,76. 8% and 2. 9% respectively. Methicillin resistant strains in S. aureus( MRSA ) and coaGulase neGative Staphylococcus ( MRCNS)accounted for averaGe of 44. 4% and 85. 5% respectively. No vancomycin and linezolid resistant strains were found. Extended spectrumβ-lactamases strains accounted for 66. 4% and 30. 6% in Escherichia coli ( E. coli)and Klebsiella spp respectively. Strains of E. coli and Klebsiella spp were still hiGhly susceptible to imipenem. Resistance rates of P. aeruGinosa and A. baumannii sppstrains to imipenem were 8. 3% and 58. 4%respectively. Conclusion The major clinical pathoGenic microorGanisms in the Ninth Peopleˊs Hospital Affiliated to medicine School of ShanGhai Jiao TonG University are still Gram neGative bacilli. Baterial resistance is serious. It is important to strenGthen the detection of resistant bacteria in routine work,which is useful for rational use of antimicrobial aGents.
