Objective: To observe the effect of Yi Jin Jing (Sinew-transforming Qigong Exercises) on the muscle strength in senile sarcopenia. Methods: Sixty-five old people with sarcopenia were randomized into Yi Jin Jing group and a blank control group. Thirty-three patients in Yi Jin Jing group practiced Yi Jin Jing (Sinew-transforming Qigong Exercises), while 32 patients in the blank control group didn't receive any interventions. The muscle strength was measured before and after 12-week training. Results: During the study, each group had 1 dropout. The muscle strength was improved after 12-week training in Yi Jin Jing group, and the difference was statistically significant (P<0.05); there was no significant difference in the blank control group (P>0.05). After the intervention, there was a significant difference between Yi Jin Jing group and the blank control group in comparing the muscle strength (P<0.05). Conclusion: Constant Yi Jin Jing (Sinew-transforming Qigong Exercises) training can notably improve skeletal muscle strength in senile sarcopenia.

OBJECTIVETo establish a rapid strip test for detection of Vibrio vulnificus.

METHODAnti-Vibrio vulnificus polyclonal antibodies were obtained from the rabbits immunized with Vibrio vulnificus (ATCC27562). Colloidal gold was prepared through reducing HAuCl(4)·4H(2)O by sodium citrate and conjugated with the polyclonal antibodies as the detecting reagent. The polyclonal antibodies and sheep anti-rabbit immunoglobulins were separately coated onto the same nitrocellulose membrane for sample detection and quality-control, respectively. The nitrocellulose membrane, gold conjugate pad, sample pad, filter paper and absorbent pad were assembled to prepare the strips. The detection specificity and sensitivity of this strip were evaluated.

RESULTSThe strip test for detecting Vibrio vulnificus yielded results in 20 to 30 min. The detection sensitivity of the test was 2×10(6) CFU/ml. The strip showed no cross-reaction with other bacterial strains. The strips remained stable after preservation at 4 degrees celsius; for 4 months.

CONCLUSIONWith a high specificity and sensitivity, this strip test is applicable in the detection of Vibrio vulnificus.

Objective To analyse the diagnosis and treatment of testicular torsion. Methods The clinical data of 66 cases of testicular torsion were retrospectively analysed. Results Among the 66 cases,32(48.5%) paid the first medical visit within 10 h,and 24(36.4%)were confirmed diagnosis at the first visit.False negative results occurred with color Doppler flow imaging(CDFI),and 8 testicles were damaged due to the false negative diagnosis.Thirty-three patients without prophylactic contralateral orchidopexy were followed up for 6 months to 20 years,and one experienced recurrent torsion. Conclusion The testicular torsion must be considered when a sudden acute scrotum pain is occurred.Testicular damage is closely related to the torsion time,and delayed medical intervention contributes to the testicular damage.Highly suspected cases should be performed surgical exploration timely due to the false negative results with CDFI.Prophylactic contralateral orchidopexy is recommended.

Objective To observe the influences of uncoupling protein 2 (UCP-2) rs660339 variants transfection on cell proliferation and apoptosis of human umbilical vein endothelial cell (HUVEC). Methods Two UCP-2 green fluorescent protein (GFP) lentivirus constructs were created with the rs660339 locus carried C or T (UCP-2C or UCP-2T), respectively. HUVEC were cultured after lentiviral infection of UCP-2C or UCP-2T. The expression of UCP-2C or UCP-2T was detected with real time polymerase chain reaction. Cell proliferation and cell apoptosis were compared among negative control (NC) group, UCP-2T group and UCP-2C group using CCK-8 cell viability and flow cytometry. Western blot and immunostaining were employed to examine the expression of Bcl-2 gene. Results The lentivirus constructs were successfully created.>80%of the transfected cells were found to express GFP under fluorescent microscope. The mRNA levels of UCP-2 gene were significantly increased (F=29.183, P=0.001) in the UCP-2T group and UCP-2C group. The CCK-8 assay revealed that on day two (F=15.970, P=0.004), day three (F=16.738, P=0.004), day four (F=5.414, P=0.045) post-infection, UCP-2T and UCP-2C group showed significantly greater proliferation than the NC cells. The apoptotic rate in the UCP-2T and UCP-2C group was significantly lower than NC group (F=277.138, P=0.000), and the apoptotic rate of UCP-2T was significantly lower than that of UCP-2C (P=0.003). The protein levels of Bcl-2 in the UCP-2T and UCP-2C group were significantly greater than that in the NC group (F=425.679, P=0.000), and the Bcl-2 expression of UCP-2T was greater than that of UCP-2C (P=0.002). The Bcl-2 density in the UCP-2T and UCP-2C group were greater than that in the NC group (F=11.827, P=0.008), while there was no difference between UCP-2T and UCP-2C group (P=0.404). Conclusion The variants of UCP-2 rs660339 may influence HUVEC proliferation and apoptosis, and UCP-2T showed a stronger effect of inhibiting apoptosis than UCP-2C.

OBJECTIVETo evaluate the feasibility and safety of laparoscopic and endoscopic cooperative surgery for treating gastric gastrointestinal stromal tumors(GIST).

METHODSRetrospective analysis was performed on the clinical data of 46 patients with gastric GIST undergoing laparoscopic and endoscopic cooperative surgery between June 2009 and June 2011 at the Renji Hospital of Shanghai Jiaotong University School of Medicine.

RESULTSThere were 27 males and 19 females with the mean age of 58.5 years. Thirty-three patients received endoscopy-assisted wedge resection, and 13 cases received laparoscopy-assisted endoscopic resection. All the operations were successful. The mean operative time was (85.5±29.3) min, the mean blood loss was (31.4±12.2) ml, the mean post-operative gastrointestinal functional recovery time was (31.6±14.9) h, and the mean post-operative hospital stay was (5.1±2.9) d. No post-operative complication occurred. NIH risk assessment showed that 34 cases were very low risk and 12 low risk. No recurrence or metastasis was found during the follow-up ranging from 2 to 26 months(median, 12.6 months).

CONCLUSIONLaparoscopic and endoscopic cooperative surgery for gastric GIST is both feasible and safe with minimal invasiveness, fast recovery and satisfactory short-term outcomes.

Objective To evaluate the validity and reliability of an item-specific physical activity scale for Chinese children and adolescents(I-PASCA). Methods Students from Grade 4-12 in Nanjing were randomly selected using a multi-stage sampling approach, 7-days physical activity (PA) level was recorded by self-reported I-PASCA and PA log and were objectively measured with accelerometers. The total moderate and vigorous PA (MVPA) time was calculated. Cronbach α was calculated to estimate the reliability of I-PASCA. Pearson correlation coefficient and Bland-Altman were used to examine I-PASCA's validity. Results There were 815 students recruited in 2013 to evaluate the reliability and validity of I-PASCA using PA log. Cronbach α for I-PASCA was 0.73 regarding moderate and vigorous PA (MVPA). The Spearman correlation coefficients of the values of PA recorded by I-PASCA and PA log were 0.59 for MVPA, and the Bland-Altman coefficient was 95.8% for MVPA. 624 students were involved to examine the reliability and validity of I-PASCA using accelerometers. Cronbach α for I-PASCA was 0.72 regarding MVPA. The Spearman correlation coefficient was 0.36 for MVPA, while the Bland-Altman coefficient was 95.5% for MVPA. Conclusions The I-PASCA, the first physical activity questionnaire specific to Chinese children and adolescents, shows acceptable reliability and validity and can be used to evaluate Chinese students' physical activity level in population-based studies.

OBJECTIVETo evaluate the relationship of hypoxia-inducible factor (HIF)-1alpha expression with chemotherapy response in gastric cancer and its clinical outcome.

METHODSLeucovorin (CF) and 5-fluorouracil (5-FU) in combination with oxaliplatin (L-OHP) were used in 52 patients with gastric carcinoma (GC) at advanced stage. CF 200 mg/m(2) was intravenous drop for 2 h at day 1 and day 14. 5-FU 1500 mg/m(2) was continuously intravenous drop for 46 h at day 1 and day 14. L-OHP 85 mg/m(2) was intravenous drop for 2 h at day 1 and day 14. Four-week was one cycle. All the patients received 4 cycles of chemotherapy at least. Chemotherapy response and clinical outcome were evaluated. Immunohistochemistry was used to examine the protein expressions of HIF-1alpha, P-gp and MRP4 by tissue microarray in GC. Twenty-seven normal gastric tissue samples were used as control group.

RESULTSThe positive expression rates of HIF-lalpha, P-gp and MRP4 in tumor samples were 53.9%, 51.9% and 57.7% respectively, which were significantly higher than those in normal gastric tissues (0, 18.5% and 14.8% respectively) (P<0.05). In cases with positive expression of HIF-lalpha, the response rate was 14.3%; whereas in cases with negative expression of HIF-1alpha, the response rate was 50.0%. There was significant difference between two groups (P<0.05). In patients of HIF-1alpha positive expression,the median progression-free survival time was 4.7 months,the median survival time was 8.8 months, and 1-year, 2-year survival rates were 37.5% and 21.5% respectively. In patients of HIF-1alpha negative expression, the median progression-free survival time was 8.4 months, the median survival time was l2.6 months, and 1-year, 2-year survival rates were 51.2% and 33.5% respectively. There were significant differences between two groups (P<0.05).

CONCLUSIONHIF-1alpha expression may be a useful indicator to predict the chemotherapy response and clinical outcome in gastric carcinoma.
