0 05), except serotype 3 from NGU patients, which was more commonly found in women than in men (P10%, respectively). Conclusion Serotype 4 was the one most frequently found and strongly related with NGU. It is suggested that the transformation from colonization to pathogenetic status be possible for serotype 3 under the influence of host and a certain environmental condition.

A simple method for the isolation and purification of ginkgolide A, B and bilobalide(ginkgo terpene trialctone) was developed. A commercially available extract of leaves of Ginkgo biloba L.containing ＞6％ ginkgo terpene trilactone was used as the raw material. After partition in EtOAc, the en-riched extract was separated to give individual terpenes by preparative liquid chromatography. GinkgolideA, B and bilobalide could be isolated with high purity by recrystallizing in MeOH-H2O.

The α chain of hemoglobin of 615 mouse was isolated and purified on CM-Celullose-23 colomn chromatography. The N-terminal amino acid of the α chain was valine determined with DABITC/PITC method.The amino acid composition was determined and it was different from the parent(C57BL)in literature on the number of leucine residue,histine residue and valine residue.An undissoluble ‘core’ and dissoluble peptides were found when the α chain of 615 mouse was hydrolysised by trypsin and it was found that the eighth amino acid residue from N-terminal of one particular peptide fragment mutated from valine (C57BL) to leucine.

Objective To explore the clinical characteristics,diagnosis and therapeutic strategies of acute appendicitis in pregnancy.Methods The clinical data of 45 cases with acute appendicitis in pregnancy,which had been diagnosed by surgeries in our hospital since Jan 2010 to Jun 2016,were retrospectively analysed.Results All patients had exhibited abdominal pain.Among them,15 patients(33.3％)had exhibited shifting pain in right lower quadrant,and 44 patients(97.8％)had abdominal tenderness.4 cases with appendiceal gangrene and 1 case with necrosis of the great omentum had been found during the surgeries.There were 5 patients had occurred complications after the surgeries,including 2 cases with poor wound healing,1 case with septic shock,1 case with inflammatory ileus and 1 case with incompletely adhesive ileus.Threatened abortion and threatened premature delivery were found in 11 patients(during 22+3 to 36+2 weeks gestation)after the surgeries.Finally,1 patient occurred abortion(25+3 weeks gestation)and 3 patients occurred premature delivery(during 28+4 to 30+4 weeks gestation).Conclusion Abdominal pain as the main clinical manifestations of the pregnancy with acute appendicitis,prone to severe complications.

Objective To explore the effect of insight education and self-confidence training on the quality of life and well-being rating of first episode schizophrenia. Methods 96 inpatients with first episode schizophrenia were randomly divided into the observed group (48 cases) in which patients were treated with risperidone plus insight education and self-confidence training and the control group (48 cases) in which patients were treated with risperidone only. These patients had been treated for 8 weeks and followed up for 0.5 year after discharged. The assessments included the Positive and Negative Symptoms Scale (PANSS),WHO QOL-100,General Well-Being Schedule (GWB) and the Self-Esteem Scale (SES) before the treatment and at the end of the following-up. Results The scores of PANSS, QOL-100, GWB and SES in both groups didn't show significant difference before the treatment (P>0.05). At the end of following-up, the total score, negative score and positive score of PANSS in the observed group were lower than that in the control group (P<0.01), while the total score of QOL-100, areas of mentality, dependence, social relation factor scores, the scores of GWB and SES in the observed group were higher than that in the control group(P<0.05 or P<0.01). Conclusion The insight education and self-confidence training can help to improve the symptom of first episode schizophrenia and enhance their quality of life and well-being rating.

Objectives To investigate the infection and colonization of Mycoplasma genitalium and Ureaplasma urealyticum in different male populations, to explore the association of M. genitalium and U. urealyticum with nongonococcal urethritis (NGU) respectively. Methods A case-controlled, cross sectional study of four different male populations was performed, namely: NGU patients (G1), non-NGU subjects attending STD clinic (G2), men who had sex with men participating in a health education program (G3), and healthy volunteers (G4). Nested PCR and culture were used to detect U. urealyticum. Nested PCR and PCR product sequencing were applied to detect M. genitalium. Results The prevalence rates of M. genitalium in the four study populations were 25.0%(25/100), 6.4%(6/94), 5.5%(6/110) and 0% respectively. Significant difference was found between each two groups except G2～G3 with a p value of 0.80. By multivariate regression analysis, controlling for the age of first sex, new sexual partners, urethritis and condom use in the previous 3 months, M. genitalium was only associated with urethritis (P= 0.004, OR = 6.754, 95% CI 1.833～24.893). The direct sequencing of PCR products showed gene mutations, in comparison with the reference sequence in GenBank, in 3 samples. The prevalence rates of U. urealyticum by PCR in 4 groups were 40.0%, 44.7%, 22.7% and 46.9% respectively, and there was no significant difference between G1～G2, G1～G4 or G2～G4 with a p value of 0.419, 0.325, 0.868 respectively, but the prevalence rate of U. urealyticum in G3 was significantly lower than that in other groups. Conclusions M. genitalium is strongly associated with NGU and the prevalence rate is significantly higher in groups with high risk sexual behaviors than that in general population. There is no association between the colonization of U. urealyticum and NGU.

Objective To investigate the effects of subcutaneous transfection of human beta-nerve growth factor (Ad-hNGFβ) gene on the expression of substance P (SP) in the dorsal root ganglion in a rat model of diabetic neuropathic pain (DNP).Methods Male SD rats weighing 180-220 g were used in this study.Ten rats were randomly collected as normal control without DNP (group C).DNP model was made by intraperitoneal injection of streptozocin (STZ) 75 mg/kg.Seventy-five rats with DNP were randomly divided into 3 groups ( n =25 each):DNP group; Ad-hNGF group and Ad-LacZ group.Groups Ad-NGF and Ad-LacZ received subcutaneous transfection of 1.12 × 1010 PFU Ad-hNGFβ 10 μl and 1.12 × 1010 PFU Ad-LacZ 10 μl respectively after pain threshold was measured on 21d after STZ injection.The mechanical and thermal pain threshold was measured before STZ injection (baseline) and at 21,35 and 49 d after STZ injection.The expression of SP in the dorsal root ganglion was determined after the measurement of pain threshold on 49 d after STZ injection.Results Compared with group C,the mechanical and thermal pain threshold was significantly decreased at each time point after STZ injection in groups DNP,Ad-NGF and Ad-LacZ,and the expression of SP in the dorsal root ganglion was signilicantly downregulated in groups DNP and Ad-LacZ (P ＜ 0.05).Compared with group DNP,the thermal pain threshold was significantly increased on 49 d afar STZ injection,and the expression of SP in the dorsal root ganglion was significantly up-regulated in group Ad-NGF ( P ＜ 0.01 ),and no significant change was found in the mechanical and thermal pain threshold and the expression of SP in the dorsal root ganglion at each time point in group Ad-LacZ ( P ＞ 0.05).Conclusion Subcutaneous transfection of Ad-hNGFβ can attenuate DNP to some extent through upregulation of the expression of SP in rat dorsal root ganglion.
