OBJECTIVE:To investigate clinical efficacy and safety of goserelin in the treatment of adenomyosis complicated with severe dysmenorrheal before placing levonorgestrel intrauterine system (LIS). METHODS:A total of 140 adenomyosis pa-tients with severe dysmenorrheal were selected from Sanya Family Planning Technology Service Center during Jan. 2014-Jan. 2016, and then divided into control group and observation group according to lottery method,with 70 cases in each group. Both groups re-ceived LIS within first 7 d of menstruation,and observation group was given Goserelin acetate sustained-release implant 10.8 mg subcutaneously via anterior abdominal wall one week before placing. Therapeutic efficacy was evaluated 6 months later. The im-provement of dysmenorrhea was compared between 2 groups. The uterine volume,COX dysmenorrhea score (CMSS),menstrual volume,hemoglobin (Hb) and CA125 content were compared between 2 groups before and after treatment. The occurrence of ADR was also compared. RESULTS:The rate of dysmenorrheal improvement in observation group was 95.71％,which was signifi-cantly higher than 81.43％of control group,with statistical significance(P<0.05). Before treatment,there was no statistical signif-icance in above indexes between 2 groups (P>0.05). Compare to before treatment,CMSS score,menstrual volume and CA125 content of 2 groups were decreased significantly after treatment,while Hb content was increased significantly;the observation group was significantly better than the control group,with statistical significance(P<0.05). There was no statistical significance in uterine volume between 2 groups before and after treatment (P>0.05). There was no statistical significance in the incidence of ADR(10.00％ vs. 14.29％)between 2 groups(P>0.05). CONCLUSIONS:Goserelin in the treatment of adenomyosis complicated with severe dysmenorrheal before placing LIS can effectively relieve dysmenorrheal,reduce menstrual volume and improve Hb and CA125 levels,but do not increase the risk of ADR.

Objective To investigate the role of Treg/CD4~+ T in the pathogenesis and prevention of bowel dysfunction after acute enteritis in rats.Methods Studies were conducted in 40 female Wistar rats with weights of 170-180 g.The rats were divided into normal control,experimental control,antibi- otics-treated,probiotics-treated and combined treated groups.The latter 4 groups were first infected with shigella flexneri by garage to establish the model of acute infectious enteritis,then normal control and experimental control group were administered 1 ml saline once everyday for 10 days.Antibiotics- treated group was given gentamycin 1 ml (8.32 mg?kg~(-)?d~(-1)) for 3 days,then was given saline 1 ml once everyday for 7 days.Probiotics-treated group was given medilac-S 1 ml (52 mg?kg~(-1)?d~(-1)) by gavage for the first 7 days,and 1 ml saline for the latter 3 days.The combined treatment group was given gentamycin for the first 3 days and medilac-S for the latter 7 days using the same dose.All rats were given colon-rectal balloon distention 16 to 22 days after the occurrence of bowel inflammation.The contraction of enteric smooth muscle was measured in vitro,the proportion of Treg cells in blood and mesenteric lymph node were analyzed by flow cytometry,and the histological changes were also observed at the same time.Statistical analyses were performed by using t test or one way ANOVA. Results No obvious changes of distal colon were histological observed in different groups.The perceptual threshold of rat gut decreased and the tension integral of enteric smooth muscle increased,and the ratio of Treg/CD4~+ T in blood and mesenteric lymph node was significantly lower in experimental control group [(4.40?0.43)%;(2.47?1.36)%] than normal controls [(5.15?0.47)%;(4.01?1.12)%,P＜0.05],while that of combined treatment group had no difference from normal controls [(4.95+0.41)%;(3.22?1.86)%].Conclusions The ratio of Treg/CD4~+ T may play an impor- tant role in the pathogenesis of post-infectious bowel dysfunction in animals.Treating acute enteritis with both antibiotics and probiotics can normalize the abnormalities,and thus prevent the occurrence of bowel dysfunction.

Background Establising the culture model of Müller cells for obtaining the highly putified target cells is essential for the study about the physiology and pathology of retinal Müller cells. The exsiting purifing method for culturing Müller cells is dissatisfactory. Objective This study was to establish a method to obtain high purifing Müller cells. Methods The retina from 5 clean newborn SD rats were isolated and digested by 0. 01% trypsin and cultured in DMEM containing 10% fetal bovine serum. The cellular suspension was then prepared,and the target cells were screened using flow cytometry based on the size and the quantity of cells. Cultured and passaged cells were identified by transmission electron microscope and light microscope. Immunocytochemistry was used to detecte the expression of GFAP in cultured cells for the determination of type and purity of the cells. Results The cells showed the similar shape to retinal Müller cells after primarily culture with the large volume, and some small other types of cells could been seen. The growth of cells was quickly 3 weeks later. The fibroblasts were removed using sticking-wall by steps,and neurons were eliminated following passage. Aboundent of cellular organs were seen under the transmission electron microscope. The positive response rate of the cells for CFAP was 100%. Conclution Flow cytometry offer a rapid and feasible approach for purifying Muller cell and it builds the foundation for further study about Müller cells.

Objective To investigate the changes of the constitution and its ratio of collagen fiber in the process of masseter reattachment following different osteotomies of the prominent mandibular angle so as to offer guidance for the resection of mandibular angle. Methods Sixteen adult goats were randomized into four groups. In group A we performed unilateral curved osteotomy of the mandibular angle. In group B unilateral curved ostectomy was performed with partial masseter resection. In group C unilateral angle splitting ostectomy, while in group D unilateral dissection of the masseter muscle was conducted. The constitution and its ratio of collagen fiber in the interface were observed at 1-month, 2-month, 3-month, and 6-month after operation. Results On the changes of collagen fiber in the process of muscular reattachment, at 1-month post-operation, the constitution of collagen fiber (types Ⅰ and Ⅲ) in groups A and B were significantly different from that of control group (P<0.05). However, both groups C and D had no statistic difference from control group (P>0.05). At 2-month, 3-month and 6-month post-operation, those of all experimental groups had no statistic difference from control group. And with time, the percentage of collagen fiber type Ⅰ increased and type Ⅲ decreased gradually. Conclusion The recovery sequences of masseter muscle reattachment in this study are firstly group C, secondly group A and finally group B. It suggests that the recoveries of mastication and other oral activities are different. Group B turns out to be with a slow muscle reattachment. Thus, we recommend treating different kinds of mandibular hypertrophy with different ostectomies.

Objective To study the value of CT angiography(CTA) and three dimensional contrast enhanced magnetic resonance angiography(3D CE-MRA) in the diagnosis of arteriosclerotic occlusive disease (ASO) of lower limb and evaluate arterial stenosis. Methods Thirty-eight patients clinically suspected ASO were studied with CTA and3D CE-MRA,twenty-two patients underwent DSA at the same time. The degree of seriousness of the stenosis shown by various imaging techniques were analyzed respectively. Results Using the DSA images as the standard reference, the sensitivity and specificity of CTA were 97.3% ,99. 1%, and MRA both were 100.0% in detecting the segments occluded. With regard the detection of segments that had more than moderate stenosis ,the sensitivity and specificity of CT were 99.3% ,97.6% ,and MRA were 97.9% ,96.4%. The degree of seriousness of the stenosis shown by MRA was overestimated than CTA on the segments that had more than moderate stenosis(x2 =5.80,P ＜0. 05). Conclusion CTA and 3D CE-MRA were reliable method in diagnosis of ASO.

Objective To assess the effect of anti- Helicobacter pylori (Hp) treatment on patients with chronic idiopathic thrombocytopenic purpura (cITP). Methods Fifty-nine patients with cITP and positive-Hp were divided into two groups by random digits table:Hp eradication group (30 cases,given a standard anti-Hp treatment) and placebo controlled group (29 cases,received a placebo). The platelet response of two groups was compared after three months' follow-up. Result The platelet response in Hp eradication group (63.3%, 19/30) was significantly higher than that in placebo controlled group (27.6%,8/29 )(χ2 = 7.59, P ＜ 0.05 ), and the increasing level of platelet count in Hp eradication group [ (33.5 ± 21.6)× 109/L] was higher than that in placebo controlled group [(12.6 ± 19.5) × 109/L] (t = 5.52,P ＜0.05).Conclusion Hp eradication treatment can promote the platelet recovery in mild and moderate cITP patients with positive-Hp.
