Objective:To observe the efficacy of auricular acupoint sticking based on conventional treatment in treating pain in early-stage extremity trauma.Methods:A hundred eligible patients with acute soft tissue injury or acute closed fracture were randomized into an observation group and a control group by their admission sequence, 50 cases in each group. The two groups both received routine management including routine checking, external fixing, traction, raising up the affected limb, etc., as well as cold compress with Chinese medication (Xiao Zhong Zhi Tong Powder). In addition to the routine management, the control group was given oral administration of amidopyrine and phenacetin compound tablet, 1 tablet per dose, twice a day, which was then taken only when necessary or terminated after pain subsided. The observation group was given auricular acupoint sticking in addition to the routine management. The two groups were compared in terms of numerical rating scale (NRS) score, therapeutic efficacy and adverse reactions after pain was relieved.Results:After the intervention, the NRS scores dropped significantly in both groups (P<0.01); the NRS score in the observation group was significantly lower than that in the control group (P<0.05).The total effective rate in the observation group was superior to that in the control group (P<0.05).There were no severe adverse reactions in the two groups.Conclusion:Based on routine management, auricular acupoint sticking can produce a more significant efficacy in treating pain in early-stage extremity trauma compared to amidopyrine and phenacetin compound tablet; it can effectively reduce pain of the affected limb and prevent complications; it's easy-to-operate and safe; patients can learn and understand it easily; its efficacy is confirmed; it enhances the satisfaction degree of the inpatients. Therefore, this method is worth promoting in clinic.

Objective To study distributive frequencies and the corelation among 6 genetical traits in Yi and Bai ethnic groups in Guizhou province. Methods According to the techniques of human population genetics and cluster random sampling,a survey on 6 genetical characters of 879 cases (Yi ethnic group 472 and Bai ethnic group 407) was carried out in October 2008,then dealt with data using SPSS13.0 software. Results The distributive frequencies in 6 dominant traits of Yi ethnic group are 20.6%,34.3%,74.4%,76.3%,25.4% and 60.8% respectively; Those of Bai ethnic group are 17.2%,39.3%,64.9%,86.2%,15.5% and 66.8% respectively. There are very significant differences(P

Aim To explore the behavior and CBS /H2 S levels of hippocampus in post traumatic stress dis-order (PTSD)rats and study the effect of exogenous H2 S on PTSD rats.Methods Single prolonged stress paradigm was adopted to prepare PTSD animal model. Morris water maze test was adopted to test space learn-ing and memory ability.CBS /H2 S content in hippo-campus tissue sample was measured using Western blot and methylene blue method.In vivo extracellular single unit recording was used to examine the frequency of spontaneous discharges of hippocampus neurons.Re-sults ① Escape latency increased and quadrant time (%)and platform crossing times decreased in Morris water maze test of PTSD group compared with normal group(P <0.01 ).CBS /H2 S level in hippocampus tis-sue of PTSD group also decreased compared with nor-mal group (P <0.01 ,P <0.05 ).② Escape latency decreased and quadrant time(%)and platform cross-ing times increased in Morris water maze test of NaHS+PTSD group compared with PTSD group(P <0.01 ).③ L-cysteine increased the frequency of spontaneous discharges of hippocampus neurons(P < 0.01 ).Con-clusions Learning and memory ability decrease in PTSD model rats owing to the inhibition of CBS /H2 S content in hippocampus tissue.The mechanism of be-havior improvement of H2 S on PTSD model rat is possi-bly related to the excitation of H2 S on frequency of spontaneous discharges of hippocampus neurons.

Objective · To analyze the clinical distribution and drug resistance of Acinetobacter junii (A. junii) and Acinetobacter lwoffii (A. lwoffii) from a grade 3A hospital in Shanghai, China, and provide the foundation for prevention and control of infections caused by them. Methods · A. junii and A. lwoffii were collected from the hospital between Aug, 2011 and Aug, 2016. VITEK2 Compact of bioMérieux (French) was used for bacterial identification and antibiotic susceptibility tests, clinical information of each strain was also analyzed. Results · 28 strains of A. junii and 58 strains of A. lwoffii were enrolled. A. junii was mainly from the departments of urology, thoracic surgery and geriatrics, and the samples were mainly sputum and urine. The resistant rates of A. junii to gentamicin, ampicillin sulbactam, piperacillin, piperacillin/tazobactam, ceftazidime, cefepime, imipenem, meropenem, levofloxacin, ciprofloxacin and cotrimoxazole were 35.71%, 3.57%, 10.71%, 3.57%, 3.57%, 3.57%, 3.57%, 3.57%, 0, 3.57% and 35.71%, respectively. A. lwoffii was mainly isolated from the departments of urology, geriatrics, respiratory and renal medicine, and the samples mainly included urine, blood and sputum. The rates of antibiotics (mentioned above) resistance were 29.31%, 13.79%, 13.79%, 6.90%, 20.69%, 18.97%, 12.07%, 15.52%, 18.97%, 31.03% and 31.03%, respectively. The levels of antibiotic resistance of these two strains were constant during the five years. Conclusion · A. junii and A. lwoffii antibiotic resistant rates were much lower than those of reported A. baumannii, the over-all antibiotic resistances of A. junii were lower than those of A. lwoffii. This study provided fundamental data for prevention or control of these two strains by empirical use of antibiotics.

To investigate the cell-killing effect and its possible mechanism of rClone30-hDR5 in combination with TRAIL on human hepatic carcinoma (HCC) cell line, first of all, recombinant plasmid pee12.4-hDR5 was introduced into HepG2 cells by liposome transfection. After five rounds of screening by flow cytometry, HepG2 cells expressing high levels of DR5 on cell surface were isolated. The cytotoxicity of TRAIL to selected cells was higher than that of TRAIL to HepG2 cells by MTT method (P < 0.01). The result suggested that the cloned hDR5 gene had biological activity. MTT assay showed that, rClone30- hDR5 in combination with TRAIL more efficiently inhibited the tumor growth of HepG2 cells compared to rClone30-hDR5 or TRAIL in vitro. The results of Annexin V-FITC/PI staining and Quantitative Real-time PCR indicated that rClone30-hDR5 in combination with TRAIL significantly increased the mRNA levels of caspase 3 and caspase 8, and induced the apoptosis of tumor cells. HepG2 cells were infected with rClone30-hDR5 or rClone30 at MOI of 1. The expression of hDR5 on tumor surface increased significantly by rClone30-hDR5 compared to that by rClone30, which contributed to the sensitivity to TRAIL. In conclusion, rClone30-hDR5 in combination with TRAIL has potential application value in cancer treatment.
