Three known compounds have been isolated from the marine sponge Gel-liodes spinosella in the South China Sea. The crude ethanol extract was partitioned between ethyl acetate and water, and then between w-butanol and water. The butanol fraction was chromatographed on silica gel column to obtain thymidine(1l) ,phenylacetic acid(2)and L-(-)-3-phenylanine(3). Their structures were determined by UV,IR,1HNMR,and 13CNMR data.

Objective To study the expression of KISS-1 in normal endometrium and in ectopic endometri-um patients with endometriosis. Methods The expression of KISS-1 in 55 cases of normal endometrium as well in 46 cases of ectopie endometriurn with endometriosis were detected by immunohistochemicai EliVision plus method. Results The positive expression rates of KISS-1 in ectopic endometriotic tissues and in normal endometri-urn were 30.43 % and 63.64 % respectively ,and the positive expression rates in ectopic endometriotic tissues signifi-cantly lower than those in the normal endometrium( P< 0.01, P < 0.05). Conclusion The decreased expression of KISS-1 may be related to the mechanism of endometriosis.

Observation revealed the abnormalities (increased CD 4 and Th, decreased Tc) in patients of Graves′ disease, and these abnormalities were not significantly adjusted after 6 weeks of treatment with methimazole (MMI), or with MMI and methotrexate (MTX), though the soluble interleukin-2 receptor and thyroid autoantibodies slightly decreased in both groups. However, the addition of MTX did not show any better effects than MMI alone in the treatment.

Objective To explore the clinical features and outcomes of patients with cerebral venous sinus thrombosis (CVT) during pregnancy and puerperium.Methods A retrospective study was performed in 24 cases of pregnant women with CVT among 15 625 deliveries in Xuanwu Hospital fromJanuary 2002 to October 2009,including 7 cases happened during pregnancy and 17 during puerperium.The etiology,clinical presentations,imaging examination results,other relevant examinations,and pregnant outcomes of these patients were analyzed.Results (1) Incidence and etiology:the incidence of CVT during pregnancy and puerperium was 0.15% (24/15 652) and 29% (7/24) of the patients fell ill during pregnancy and 71% (17/24) during puerperium.Five were complicated with severe preeclampsia,while another 5 complicated with hyperemesis.One woman was complicated with anemia.CVT was identified after spontaneous delivery in 9 cases and 8 after cesarean section.(2) Clinical presentations:Among the 24 CVT cases,22(92% ) suffered from headache,16(67% ) reported nausea and vomiting,15(63% )experienced hyperspasmia and 6 (25%) complained of blurred vision.On admission,8 (33%) patients were unconscious,3 (13%) with hemiplegia,and 8 (33%) were febrile.(3) Imaging and laboratory examinations:twelve patients underwent digital subtraction arteriography ( DSA) and were diagnosed.Fifteen women showed superior sagittal sinus thrombosis in MRI and magnetic resonance intravenous angiograph(MRV).Examination of the fundus found papilledema in 4 cases.Normal cerebral sinus fluid and laboratory routine tests were reported in 13 cases,but 6 cases of hyperlipidemia,7 cases of abnormal activated partial thromboplastin time ( APTT),5 cases of abnormal international normalized ratio (INR),3 cases elevated platelet count,4 cases of positive D-dipolymer,1 cases of low hemoglobulin level ( <10 g/L),4 cases with abnormal hematocrit,and 10 cases of elevated fibrinogen ( > 4 g/L) were identified.(4) Management and pregnancy outcomes; among the 7 cases happened during pregnancy,2 were complicated with severe preeclampsia and delivered through cesarean section immediately and discharged after proper management including depressurization,spasmolysis,dehydration and anticoagulant therapy.Five of the 7 cases presented with CVT during early pregnancy,among which 1 was discharged after dilation and curettage followed by anticoagulant therapy,2 received endovascular thrombolysis after which one was discharged and the other one left with right hemiparesis and 2 patients died.Among the 17 patients presented with CVT during puerperium,10 received anticoagulant therapy after which 4 were fully recovered,5 left with functional disturbance (3 with hemiplegia,1 with incomplete motor aphasia and hemiparesis and 1 with blurred vision) and one died.Among the rest 7 cases who underwent endovascular thrombolysis,3 were fully recovered,3 left with functional impairment ( 1 with blind and headache and 2 with hemiplegia),and one died.Altogether,there were 14 patients underwent systemic anticoagulant therapy after which 7 were fully recovered,5 left with dysfunction and 2 died.Among the 10 cases received endovascular thrombolysis,4 were fully recovered,4 remained some dysfunction and 2 died.Conclusions CVT,mostly presented as superior sagittal sinus thrombosis,are more common in puerperium than during pregnancy and DSA is the golden standard for the diagnosis of CVT.Anticoagulant therapy and endovascular thrombolysis are effective in the treatment of CVT,but may left the patients with functional disturbance or even death.Prompt diagnosis and treatment ensure a better outcome for pregnant women complicated with CVT.

BACKGROUND: Traditional orthodontic anchorage has the disadvantages of discomfort, difficult to control, affecting the appearance, and relying on patient’s close cooperation. Because of short-time clinical research and application, mini-implant anchorage has a great controversy in the orthodontic treatment. OBJECTIVE: To explore the application value of mini-implant anchorage in the orthodontic treatment. METHODS:Eighty cases undergoing the orthodontic treatment at the Center of Ophthalmology and Otolaryngology, Yaan People’s Hospital in China from January 2012 to June 2015 were enrol ed in this study. These patients were equal y randomized into test group and control group, which were subjected to mini-implant anchorage or headgear anchorage, respectively. The treatment was continued for 2 years in the two groups. RESULTS AND CONCLUSION: After the treatment, the successful rate in the test group was significantly higher than that in the control group (P < 0.05); the upper central incisor convex distance difference, inclination angle of the upper central incisor, displacement of the molar, SNA angle, inter-canine width, were significantly better in the test group than the control group (P < 0.05). At weeks 4 and 8 after intervention, there was no difference in the expression of osteoprotegerin in the periodontal tissue between the two groups (P > 0.05), but the rate of adverse reactions was significantly lower in the test group than the control group (P < 0.05). These findings indicate the mini-implant anchorage method can significantly improve the therapeutic efficacy, improve the success rate of treatment, and reduce the incidence of postoperative infections, which has good safety and stability, and has good clinical application value.

Objective To comprehensively evaluate the effect of the program of treatment and assistance to advanced schis-tosomiasis patients in Hunan Province from 2004 to 2013. Methods The fund investment of the program,the profits of hospi-tals and the improvement of the patients’health were investigated by data collection and questionnaire survey. The evaluation index system of treatment and assistance to advanced schistosomiasis in Hunan Province was constructed by the Delphi method and analytic hierarchy process,and the program was assessed comprehensively. Results The evaluation index system includ-ing 6 primary indices and 33 secondary indices was established. Among all the primary indices,the score of the treatment and assistance(22.25)was the highest,and that of the satisfaction assessment(8.15)was the lowest,and the score of the compre-hensive assessment was 87.06. The average cure rate of the patients was 13.08%from 2004 to 2013. More than 60%of the pa-tients’disease condition got better,and nearly 70%of the patients’psychological condition improved,and more than 70%of patients’self-help ability and social contact improved,as well as family happiness increased. In addition,the annual average cost for caretakers decreased by 2000 Yuan,and the profits of all the fixed-point hospitals for treatment and assistance in-creased. Conclusion The effectiveness and efficiency of the treatment and assistance to advanced schistosomiasis patients in Hunan Province is obvious,and the government should continuously invest in the program.

Aim To investigate the effects of all-trans retinoic acid and benazepril on the expression of ?-smooth muscle actin in rats with glomerulosclerosis.Methods 80 Wistar male Rats were randomly assigned into the following groups: control group,model group,ATRA treatment group and benazepril treatment group,20 rats in each group.GS rats were uninephrectomized and injected with adriamycin(5mg?kg-1) after one week through the tail vein.All rats were sacrificed at the 12th week,GS was evaluated by glomerulosclerosis index(GSI) system.The expression of ?-SMA was assessed by reverse transcription-polymerase chain reaction(RT-PCR) and immunohistochemistry.Results Comparing with control group,the expression of ?-SMA mRNA and protein were decreased significantly in ATRA treatment group and benazepril treatment group(P0.05).Conclusions The postponed effects of ATRA and benazepril on GS were evident and equivalent.

Objective To explore the effects of skill-training on social function in patients with schizophrenia recession. Methods 60 patientswith schizophrenia recession were divided into 2 equal groups (n=30) for 1-year treatment. The control group was treated only withdrugs, and the treatment group was treated with skill-training in addition. The patients were assessed with the Scale of Social Skill of ChronicSchizophrenic Inpatients (SSSI) and the Positive and Negative Symptom Scale (PANSS) before, 6 months and 12 months after treatment.Results The total scores of PANSS decreased significantly in the treatment group compared with the control group (P<0.01). The scores ofSSSI decreased significantly in the treatment group after treatment. However, there was no significant differences in the control group (P>0.05) 6 months after treatment, but was 12 months after treatment (P<0.05). Conclusion Based on the medicine treatment, skill-training mayimprove the flinched mental symptom to remain the social function.
