OBJECTIVE: To test the reliability and validity of Health Scale of Traditional Chinese Medicine (HSTCM) by means of questionnaires. METHODS: A cross-sectional survey was conducted at Liwan Community of Guangzhou, Old People's Home in Guangzhou and Outpatient Department of the Second Affiliated Hospital of Guangzhou University of Chinese Medicine. A total of 652 Chinese individuals (over 18 years old) were assessed with the 88-item version of HSTCM and World Health Organization Quality of Life Measure-Abbreviated Version (WHOQOL-BREF), which were randomly delivered to them. Some socioeconomic characteristics were registered. RESULTS: A test-retest reliability (15-day interval) was found among the 76 persons who completed the questionnaires by themselves. Intra-class correlation coefficient (ICC) was 0.93. Associated 95% confidence interval (CI) was 0.89-0.96. Split-half reliability was 0.79. Inter-investigator reliability (0.93) was also good, and the ICC of HSTCM was 0.90 (95%CI 0.67-0.97). The correlation between HSTCM and WHOQOL-BREF was -0.66. The correlations of HSTCM and questionnaire deliver order, investigator, interview date and interview time were 0.06, -0.12, -0.17 and 0.20 respectively. The correlation between HSTCM and self-rated health (0.46) was greater than that between HSTCM and chronic illness (0.28). Divided by individuals with or without chronic illness, area under the ROC (receiver operator characteristic) curve for HSTCM was 0.67 (95%CI 0.63-0.71). CONCLUSION: It indicates that the HSTCM is conceptually valid with satisfactory psychometric properties and forms a basis for further applications in clinical research of traditional or integrative medicine.

Objective To investigate the protective effects and the mechanisms of 17β-estradiol on the propofol-induced neuroapoptosis in primary cultured rat cortical neurons.Methods The neurons were cultured for 7 days and then divided into three groups: vehicle-control group ( treated with equal volume of 20% intralipid ) , propofol-treated group ( treated with 500μmol/L propofol) , and propofol plus 17β-estradiol treated group ( treated with 500μmol/L propofol and 0.1 μmol/L 17β-estradiol).12 hours after the treatment, neuroapoptosis was detected by Hoechst 33258 staining and TUNEL assay, and the levels of Bcl-2, Bax and cleaved caspase-3 proteins were detected by Western blot.Results Compared with the vehicle-control group, the neuroapoptosis increased greatly ( P<0.01 ) , Bcl-2 level reduced ( P <0.01), Bax and cleaved caspase-3 levels increased greatly (P<0.01), and Bcl-2/Bax ratio reduced significantly (P<0.01).Compared with the propofol-treatment group, the neuroapoptosis decreased greatly ( P <0.01), Bcl-2 level increased ( P<0.01 ) , Bax and cleaved caspase-3 levels reduced greatly ( P <0.01 ) , and Bcl-2/Bax ratio increased greatly ( P <0.01 ) . Conclusions 17β-estradiol can protect cortical neurons against propofol-induced cortical neuroapoptosis by regulating the expression of Bcl-2 and Bax.

Objective To examine an in vivo method for the differentiation of induced pluripotent stem cells (iPSCs) into thymic epithelial cells (TECs) in mice. Methods Green fluorescent protein-expressing iPS cells, derived from C57BL/6 mice, were injected into blastocysts from ICR mice. Chimeric blastocysts were then transferred into uteri of E2.5 pseudopregnant mice. Chimeric mouse could be identified by coat color 10 days after birth. The chimeric thymus was transplanted under the renal capsule of BALB/c nude mice. The spleen was cut out from the thymus-transplanted nude mice and the cells were dispersed and analyzed by a flow cytometer 4 weeks after transplantation. Results Chimeras were born 17 days after embryo transfer and 13 live-born chimeras were obtained. The contribution of iPSC-derived cells in the chimeras ranged from 5% to at most 90%. Typical thymic epithelium structure consisted of green fluorescent protein-expressing cells in chimera. The iPSCs-derived thymic epithelial cells could support the generation of new T cells. Conclusion The results indicate that mouse iPS cells can differentiate in vivo towards normally functioning TECs.

Objective To investigate the treatment of acute obstructive colorectal cancer.Methods The clinical data of 26 cases with acute obstructive colorectal cancer were analysed retrospectively and relevant literatures were reviewed.Results Radical right hemicolectomy was performed in 9 patients with obstructive right colonic cancer.Among 17 patients with obstructive left colorectal cancer,one-stage radical resection was perfomed in 12 cases,including one-stage anastomosis in 4 cases and Hartmann's operation in 8 cases.Palliative colostomy was performed in 3 cases.Right hemicolectomy and sigmoid colon loop colostomy was performed in 1 case of rectum cancer with ascending colon strangulation.One case refused surgery.Two cases died of MODS and 1 case with inflammatory ileus recovering from conservative treatment after operation.In the course of disease,septic shock and MODS happened in 3 cases,lung infection in 5 cases,heart disease in 2 cases and Hypoalbuminemia in 16 cases.Conclusions One-stage radical colectomy and anastomosis should be performed in patients with obstructive right colonic cancer.In order to reduce toxin absorption and prevent the deterioration of disease,Bowel decompression and removal of inflammatory exudate should be performed in patients with obstructive left colorectal cancer according to the damage control theory.Then effective and safe operation should be chosen in accordance with patients' status.Anti-infection and nutrition support treatment must be strengthened after operation.
