Rhynchosia volubilis Lour has been a major drug in a folk prescription for contraception in China, whereas its mechanism remains unknown. Its antifertility effects on male mice and antimicrobial activities on sexually transmitted infection (STI) pathogens were previously reported. This study was undertaken to develop the n-Butanol extract of Rhynchosia volubilis Lour (BERVL) as a spermicidal agent with STI prevention. The spermicidal activities of BERVL with different doses were assessed using selected high-motile sperms of normal human semen samples, and their inhibitory effects on Lactobacillus acidophilus were determined. The mechanism of the spermicidal activity was explored by aqueous Eosin Y and Hoechst 33342/PI staining. The results showed spermicidal activities and inhibitory effects of BERVL on Lactobacillus acidophilus were dose-dependent. Dose of 90 mg/mL BERVL terminated all progressive sperm motility within 2 min, and had slight inhibitory effect on Lactobacillus acidophilus, suggesting it was an effective and safe dose for contraception use. About 80% sperms exposed to BERVL displayed changes consistent with high permeability of head membrane. It is concluded that BERVL as spermicide has advantages over N-9 with strong ability to instantaneously kill human sperm and possesses light inhibitory effect on Lactobacillus acidophilus.

Objective To investigate the co-morbid state of mental disorder in patients with functional dyspepsia (FD) in a tertiary general hospital in China and explore the risk factors of the co-morbidity of FD and major depressive disorder(MDD).Methods This study was designed as a bilateral evaluation and structural psychiatric interview.Patients with FD and newly diagnosed outpatients with MDD in gastrointestinal and psychological departments were enrolled.FD was defined by Rome Ⅲ criteria.The questionnaires including symptoms of FGIDs Roma Ⅲ,the composite international diagnostic interview (CIDI 3.0) Chinese version,the Hamilton depression/anxiety rating scale (HAMD/HAMA),Montgomery-Asberg depression scale (MADRS) were involved in this study.All patients were administered by well trained physicians and investigators in face to face interview.Results A total of 69 patients have completed the valid questionnaires and interview,among whom 42 met FD criteria (FD group) and 27 with FD co-morbid MDD (co-morbid group).Male to female ratios were 17∶25 and 10∶ 17,the mean age (42.1 ± 13.3) and (43.1 ± 15.3)years respectively.The life-long co-morbidity of FD and MDD was 39.1％ (27/69),while 31.9％ (22/69) patients with FD were accompanied with other mental disorders rather than MDD.Patients in FD co-morbid MDD group had significantly more severe depression than those in FD group with HAMD-17 score 21.6 ± 8.0 and 14.5 ± 7.6,HAMA score 21.2 ± 9.0 and 14.9 ± 7.5 respectively (all P ＜ 0.01).Logistic regression analysis showed that high score of MADRS and complication with functional anorectal disorder may be the risk factors of FD co-morbid MDD [OR (95％ CI) 1.12 (1.06-1.19) and 7.07(1.12-44.53)].Conclusions The co-morbidity rate of FD with MDD in our hospital is high.In addition to MDD,other mental disorders also need to be paid attention in FD patients.FD co-morbid MDD patients suffered more severe depression and anxiety.The high score of MADRS and complication with functional anorectal disorder seem to be the risk factors of co-morbidity of FD and MDD.

Objective To confirm the distribution of high arsenic drinking water and the situation of endemic arsenism in Hubei Province, to provide reference basis for prevention and control of endemic arsenic disease. Methods Using typical investigation and sample investigation in 2006 and 2007, the arsenic content of water was detected sampled from 19 counties(cities or communities). And those water samples which were close to or exceeded the stipulated standard were rechecked by the national standard method. Furthermore, the situation of endemic arsenism was investigated in the cities having high arsenic contents of water. Results In 2006,10 028 water samples of 446 villages in 6 counties (cities or communities) were tested, the wells of high arsenic (> 0.05 mg/L) were found in 5 counties (cities or communities) and the proportion of the well that exceeded stipulated standard was 5.29%(530/10 028); In 2007,19 086 water samples of 1282 villages in 17 counties(cities or communities) were tested, the wells of high arsenic were found in 11 counties(cities or communities), and the proportion of the well that exceeded stipulated standard was 1.74%(333/19 086). In these two years, 29 114 water samples were tested, in which 863 water samples were exceeding the stipulated standard. The 2.96% of total wells exceeded stipulated standard and mainly distributed in 179 villages of 12 counties(cities or communities). And the highest arsenic content of water sample was 2.012 mg/L. In the endemic arsenism area, 2 critical, 1 moderate and 1 mild arsenism patients had been found. Conclusions The water of high arsenic content are scattered in Hubei Province and the situation of endemic arsenism disease is mild. Improving water aiming at decreasing arsenic and establishing patient files should be carried out immediately.

Objective Inflammation response is involved in the whole pathological process of acute cerebral infarction ( ACI) , but few reports are seen on its clinical implication in ACI patients .The purpose of this study was to investigate the predictive value of the differential count of leukocytes for stroke severity and early clinical outcomes in the acute phase of cerebral infarction . Methods We collected the clinical and laboratory data of 635 patients diagnosed with ACI within 72 hours of symptom onset and eval-uated the association between the differential count of peripheral blood leukocytes and stroke severity at admission and within 3 days af-ter admission as well as the clinical outcomes at discharge .The neural function impairment scores of the patients were obtained with The NIH Stroke Score ( NIHSS) at admission and on the third day after admission , and the therapeutic results evaluated with the modi-fied Rankin Scale ( mRS) , mRS >2 as poor prognosis .Analyses were performed on the correlation of the differential count of leuko-cytes with NIHSS and mRS scores and its influence on the ACI patients . Results At discharge , the mRS related influencing factors included the total count of leukocytes (OR=1.147, 95% CI:1.038-1.268), count of neutrophil cells (OR=1.227, 95% CI:1.00-1.369 ), count of lymphocytes ( OR =0.508, 95% CI:0.342-0.753), and neutrophil to lymphocyte ratio (NLR) (OR=1.150, 95%CI:1.008-1.314).the NIHSSs were correlated with the counts of leucocytes (r=0.078, P=0.024), neutrophil cells (r=0.083, P=0.019), and lymphocytes (r=0.010, P=0.004) at admission, and with the counts of leucocytes ( r =0.238, P <0.001), neutrophil cells (r=0.335, P<0.001), lymphocytes (r=-0.269, P<0.001), and NLR (r=0.423, P<0.001) on the third day after admission. Conclusion In the acute phase of cer-ebral infarction , the differential count of leukocytes and NLR are valuable for predicting the severity of neurologic impairment and early poor functional outcome .
