Objective To observe the clinical efficacy of triple needling at myofascial trigger points plus warm needling in treating periarthritis of shoulder. Method Eighty patients with periarthritis of shoulder were randomized into a treatment group of 44 cases and a control group of 40 cases. The treatment group was intervened by triple needling at myofascial trigger points plus warm needling, while the control group was by warm needling alone. The two groups were treated once a day, 10 times as a treatment course. The Pain Rating Index (PRI), Visual Analogue Scale (VAS), Present Pain Intensity (PPI), and motion of shoulder joint were observed before the treatment and after 2 treatment courses, and the clinical efficacies were compared between the two groups.Result In the treatment group, the PRI, VAS, and PPI scores respectively after 1 and 2 treatment courses were significantly different from those before the treatment (P<0.05,P<0.01). In the control group, the scores after 2 treatment courses were significantly different from those before the treatment (P<0.05). After 2 treatment courses, the scores in the treatment group were significantly different from those in the control group (P<0.01). In both groups, the motions of shoulder joint respectively after 1 and 2 treatment courses were significantly changed compared with those before the treatment (P<0.01). The motions of shoulder joint in the treatment group were significantly different from those in the control group respectively after 1 and 2 treatment courses (P<0.05,P<0.01). The recovery plus markedly-effective rate and total effective rate were respectively 70.5% and 95.5% in the treatment group, versus 52.5% and 90.0% in the control group, and the between-group differences were statistically significant (P<0.01,P<0.05).Conclusion Triple needling at myofascial trigger points plus warm needling is an effective approach in treating periarthritis of shoulder.

Objective To evaluate the image quality,diagnosis accuracy and dose reduction of split-bolus CT urography (CTU) with low voltage scan and sinogram affirmed iterative reconstruction (SAFIRE).Methods A total of 80 cases of consecutive patients with confirmed or suspected urinary system disease needed CTU examination were divided into two groups (control group and test group) by using random number table.In control group,convention scan (120 kV) with one time injection was used.But low voltage scan (80 kV) with SAFIRE algorithm and split-bolus injection (SBI) was used in experiment group.The radiation dose,image quality and diagnosis accuracy were compared.Results A total of 77 cases completed CTU examination successfully in the two groups,including 39 cases in control group and 38 cases in test group.The effective dose reduced from (26.68 ± 4.07) in control group to (3.93 ± 0.85) mSv in test group (t =-33.78,P ＜ 0.05).Subjective image quality score was (4.49 ± 0.79) in control group and (4.39 ± 1.53) in test group,with no significantly statistical difference (Z =2.71,P ＞ 0.05).Signal-to-noise ratio (SNR) of objective image quality in test group was higher than that in control group (127.3±15.9 vs.109.6 ± 13.2,t =4.49,P＜0.05).But there was no significantly statistical difference in contrast-to-noise ratio (CNR) between control group(100.8 ± 12.9)and test group (109.0 ± 14.4,P ＞ 0.05).For diagnosis accuracy,no statistical difference were found between two groups(84.62％ and 81.58％,P ＞ 0.05).Conclusions The combination of low voltage scan with SAFIRE algorithm and split-bolus injection CTU could reduce the radiation dose significantly,but the objective image quality,CNR (except SNR) of subjective image quality and diagnosis accuracy were all unaffected obviously.

Objective To investigate the effects of metformin(Met)on the proliferation of pancreatic cancer cells under different glucose concentration culture conditions,and to find the potential role of miR-139-5p in the process.Methods PANC-1 cells were treated with different concentrations of metformin(0/5/10/20 mmol/L)in 25 mmol/L(high-glucose group,HG)or 5 mmol/L(normal-glucose group,NG)glucose culture,cell proliferation,apoptosis,migration and cell cycle were detected after 48 h.The expression of miR-139-5p was quantitatively detected by RT-qPCR,and the miR-139-5p mimics were transfected into PANC-1 cells to clarify the role of miR-139-5p.Results Metformin inhibited the proliferation,promoted apoptosis,and induced S phase and G2/M phase arrest of PANC-1 cells under in high glucose and normal glucose culture conditions,and its anti-proliferation and pro-apoptosis effects were more significant in the normal glucose groups.The expression of miR-139-5p was up-regu-lated by metformin treatment in normal but not in high glucose culture.Further studies showed that miR-139-5p mimics inhibited of PANC-1 cells proliferation without metformin pre-incubation and enhanced the anti-prolifera-tion effect of 5 mmol/L metformin.The pro-apoptotic effect of 10 mmol/L metformin in normal glucose culture conditions.Conclusions In normal-glucose culture conditions,metformin can inhibit proliferation,induce apop-tosis and cell cycle arrest of PANC-1 cells more significantly than in higher-glucose culture,which may be partly related to the up-regulation of miR-139-5p.

The purpose of this study is to evaluate theretention capabilities of poloxamer-basedhydrogels for vaginal application with nonoxinol-9 as the model drug. Twohydrogel formulations, which contained 18% poloxamer 407 plus 1% poloxamer 188 (GEL1, relative hydrophobic) or 6% poloxamer 188 (GEL2, relative hydrophilic), were compared with respect to the rheological properties,hydrogel erosion and drug release. The vaginal retention capabilities of these hydrogel formulations were further determined in two small animal models, including drug quantitation of vaginal rinsing fluid in mice and isotope tracing withTc in rats. The two formulations exhibited similar phase transition temperatures ranging from 27 to 32 °C. Increasing the content of poloxamer 188 resulted in higher rheological moduli under body temperature, but slightly accelerated hydrogel erosion and drug release. When compared, GEL1 was eliminated significantly slower in rat vagina than GEL2, while the vaginal retention of these two hydrogel formulations behaved similarly in mice. In conclusion, increases in the hydrophilic content of formulations led to faster hydrogel erosion, drug release and intravaginal elimination. Rats appear to be a better animal model than mice to evaluate thehydrogel for vaginal application.

Objective: To analyze the survival time of people living with HIV/AIDS and related influencing factors in Sichuan province during 1991-2017. Methods: A retrospective cohort study was conducted to analyze the data of 143 988 HIV/AIDS cases. The data were collected from Chinese HIV/AIDS Comprehensive Information Management System. Life table method was used to calculate the survival proportion of the cases, and Cox proportion hazard regression model was used to identify the factors related with survival time. Results: Among 143 988 HIV/AIDS cases a total of 30 420 cases died of AIDS related diseases (21.1%) and the average survival time was 11.51 years (95%CI: 11.39-11.64). Multivariate Cox regression analysis showed that the influencing factors for the survival of HIV/AIDS cases were gender (male vs. female, HR=1.35, 95%CI: 1.32-1.40), education level (primary school or below vs. junior middle school: HR=1.15, 95%CI: 1.12-1.18), ethnic group (Han vs. other ethnic groups, HR=1.46, 95%CI: 1.41-1.52), occupation (farmer vs. other occupations: HR=1.26, 95%CI: 1.22-1.29), age (≥55 years old vs. 15-24 years old: HR=3.18, 95%CI: 3.02- 3.36), disease phase (AIDS vs. HIV infection: HR=1.44, 95%CI: 1.39-1.48), antiretroviral therapy (ART) (receiving ART vs. receiving no ART: HR=0.20, 95%CI: 0.19-0.20), and CD₄⁺T cell counts at diagnosis (>500 cells/μl vs.<200 cells/μl: HR=0.42, 95%CI: 0.40-0.45). Conclusions The average survival time of HIV/AIDS cases was 11.51 years in Sichuan during 1991- 2017. The risk factors for the survival of the cases were male, education level of primary school or below, Han ethnic group, farmer, old age at diagnosis, disease phase, The protective factors for the survival of HIV/AIDS cases were receiving ART and higher CD₄⁺ T cell counts at diagnosis.
