Objective To explore the mechanism of combined treatment with methotrexate (MTX) and Ga-Al-As laser irradiation for rheumatoid arthritis (RA) and to assess the effectiveness of Ga-Al-As laser therapy for RA. Methods Twenty-two patients with RA were randomly and evenly divided into two groups: the treatment group treated with Ga-Al-As laser irradiation combined with MTX and the control group treated with MTX only. Ten age-matched normal subjects were observed as normal controls. The amount of CD4 + CD25 + regulatory T cells in peripheral blood (PB) of the normal controls and that in the PB and synovial fluid (SF) of the 22 patients before and after therapy were counted by flow cytometry. Meanwhile, the amount of prostaglandin E2 (PGE2) in synovial fluid of the patients was measured before and after treatment by enzyme-linked immunosorbent assay(ELISA). Results After combined treatment the clinical symptoms of the patients were improved significantly, and the amount of PGE2in SF decreased significantly. The count of CD4 + CD25 + regulatory T cells in PB of RA patients was ( 3.84 ±3.20) % , compared to ( 10.05 ± 7.04) % in healthy individuals. The count of CD4 + CD25 + regulatory T cells in SF of RA patients was ( 14.89 ± 12.30) % , much higher than that in PB. The count of CD4 + CD25 + regulatory T cells in SF decreased significantly in treatment group compared to control group (P ＜0.05). Conclusion Ga-Al-As laser irradiation eombined with MTX can effectively improve the clinical symptoms of RA patients. It may be related to the decrease of amount of PGE2 and count of CD4 + CD25 + regulatory T cell in PB and SF.

Objective To observe the effect of ritodrine hydrochloride on peripheral blood and tocolysis rate of patients with threatened premature labor.Methods89 cases of patients with threatened premature labor were selected from October 2015 to September 2016 and randomly divided into two groups, research group with 45 cases treated with ritodrine hydrochloride and control group with 44 cases treated with epsom salt.The peripheral blood, extinction time of uterine contraction, extended days of pregnancy, postpartum hemorrhage, neonatal birth weight and tocolysis rate were compared between two groups.ResultsAfter treatment, CRH, NO, PGE2 and IL-8 of control group were obviously higher than research group, the difference was statistically significant (t=10.826,3.839,7.534,8.075,P<0.05).The extinction time of uterine contraction in control group was obviously longer than research group, while extended days of pregnancy and neonatal birth days in research group were obviously longer than control group, the difference was statistically significant (t=4.566,7.855,3.237,P<0.05).There was no significant difference in postpartum hemorrhage between two groups (t=0.889,P>0.05).The overall efficacy of tocolysis in control group was 70.5%, while that in research group was 86.7%, which was obviously higher than the control group, the difference was statistically significant (χ2=7.801,P<0.05).ConclusionRitodrine hydrochloride can effectively control uterine contraction factor in peripheral blood and extend gestational days of patients with threatened premature labor, so as to improve tocolysis rate and birth quality.

Objective To investigate the effect of Propess on cervical collagen remodeling and cervical ripening in full-term pregnancy.Methods 94 cases of mid-term pregnant women enrolled in obstetrics and gynecology of our department from January 2016 to January 2017 were divided into two groupaccording to the random number table method.47 cases of the control group, taking oxytocin intravenous infusion;observation group of 47 cases, taking propess suppository vaginal medication.Labor time, medication to labor time, cervical Bishop score, mode of delivery, postpartum hemorrhage and neonatal situation of two groups were compared.Results Compared with the control group, the Bishop score of the cervix was increased, the total effective rate of cervical ripening was improved, the labor was shortened, the time of medication was shortened, and the delivery rate of vaginal delivery was improved(P<0.05), while the two groups were bleeding, neonatal Apgar score and the incidence of fetal distress were not statistically significant.Conclusion It can promote cervical collagen remodeling, promote cervical ripening, thereby reducing the rate of cesarean sectionwith taking propess in the vaginal.

A method of derivatization at injection port following three phase hollow fiber microextraction with tetramethylammonium hydroxide (TMAH) as a dual-function reagent, for the simultaneous determination of salicylic acid, p-hydroxybenzoic acid, cinnamic acid, vanillic acid, p-coumaric acid and ferulic acid in beers by gas chromatography was developed. Phenolic acids were extracted from aqueous samples to a thin layer of organic solvent ( hexyl acetate) phase impregnated into the pores of the hollow fiber wall, and then back extracted to an acceptor solution (TMAH) located inside the lumen of the hollow fiber. Upon injection, the phenolic acids were derivatized to their methyl esters in the GC injection port. Several parameters related to the derivatization and extraction efficiency were optimized. The optimized conditions were as follows: hexyl acetate was used as the extraction solvent, an aqueous solution of TMAH (5% W/ V) was used as the derivatization reagent and acceptor phase, the pH value of donor phase was 2. 0, the concentrations of NaCl was 25% W/ V, the stirring rate was 500 r/ min, the extraction time was 40 min. Under the optimal conditions, the linear range of phenolic acids was 0. 50 -15. 00 mg / L, the limits of detection were 0. 05 -0. 18 mg / L. The proposed method was applied to the determination of the phenolic acids in beers. Vanillic acid, p-coumaric acid and ferulic acid were found in the beer samples, others were not detected. The spiked average recoveries were 90. 1% -106. 8% and RSD% was less than 5. 9% (n =3). The method is suitable for the determination of phenolic acids in beers.

Objective: To analyze the trends of development and equity of health institutions in China during the period from 2002 to 2013 , and put forward references to optimize the decision-making on health resources alloca-tion. Methods:Statistical map, Gini coefficient and other methods were used to analyze the distribution and equity of health institutions in China for 12 years, during the period from 2002 to 2013. Results:(1) The overall development of health institutions is on the rise in China, and the distribution density of health resources with the population ad-justment is opposite to the adjustment of both population and geographic area at the same time. (2) In the past 12 years, the number of tertiary hospitals showed an increasing trend, and growth in the eastern region was the most sig-nificant. (3) From 2002 to 2013, the Gini coefficient of the number of health institutions and beds per 1,000 per-sons per square kilometer was maintained at 0. 40, and decreased from 0. 70 to 0. 60 in the eastern region of China, respectively. This same number was maintained at 0. 40 and 0. 20 in the central and western region. Conclusion: In China, the fairness trend of health resources allocation has improved during the period from 2002 to 2013, but the imbalance is more serious in the eastern region than in the central and western regions. It should be paid more atten-tion to optimizing the health resources allocation according to the local conditions of different regions, especially the influence of geographical distribution.
