Objective To evaluate the value of transvaginal ultrasonography in diagnosis of ovarian pregnancy. Methods Ultrasound features of 21 cases of ovarian pregnancy were retrospectively studied in comparison with those of surgery and pathology. Results All the cases were diagnosed extrauterine pregnancy and suggested 3 cases with the lesion localizing inside the ovary,3 cases superficial to the ovary, 1 case unclear localization and 2 cases misdiagnosed as tubal ectopic pregnancy, the correct localization was made in 66.7 % of 9 unruptured cases by endovaginal sonography. Twelve ruptured cases were unclear localization by endovaginal sonography. The sonographical appearance of ovarian pregnancies showed normal or little bigger uterus, empty uterine cavity, a gestational sac or inhomogenous strong echoes interior or superior to the ovary, or complex mass in the adnexal area with abundant free fluid in the pelvic. Conclusions Transvaginal sonography is of diagnostic value in ovarian unruptured pregnancy.

Poly (β-amino ester)s (PβAEs) contain tertiary amine backbones and biodegradable ester bonds, making them highly biocompatible and pH-responsive. Meanwhile, originated from combinatorial libraries, PβAEs are simple to synthesize, easy to obtain raw materials and can be easily adapted to meet the different performance needs of gene carriers by adjusting the monomer type, monomer ratio and reaction time. Therefore, PβAEs are promising material for non-viral gene carriers. This paper provides a comprehensive overview of the properties and synthesis of PβAEs gene carriers and summarizes the progress of research on the gene delivery of each type of PβAEs.

Aim To explore the possible anti-inflammation mechanism of paeonol by investigating its effects on the MMP-9 mRNA expression and cytokines production in human dermal fibroblasts induced by TNF-?.Methods The effect of paneonol on the expression of MMP-9 mRNA was detected by semi-quantitative RT-PCR.The modulation of paneonol on the production of IL-1?,IL-6 and IL-8 in fibroblasts was measured by ELISA.Results MMP-9 hardly expressed in human dermal fibroblast.The results also showed that TNF-? significantly induced the expression of MMP-9 in fibroblasts and at the same time paeonol inhibited the expression of MMP-9.TNF-? stimulated the production of IL-1? and IL-8 in fibroblasts,while 10~100 mg?L-1 paeonol inhibited TNF-?-induced IL-1? and IL-8 production in fibroblasts but had nothing to do with the production of IL-6.Conclusions Paeonol can inhibit the expression of MMP-9 mRNA,IL-1? and IL-8 induced by TNF-?.

Objective To preliminarily test the value of gastroesophageal reflux disease questionnaire (GERD-Q) in auxiliary diagnosis of gastroesophageal reflux disease(GERD) in infants and young children.Methods From January 2011 to February 2014,148 infants and 87 young children with suspected GERD symptoms were enrolled in the outpatient and inpatient departments of Wuhan Women and Children's Medical Care Center.The diagnosis of GERD were made through 24 h esophageal pH monitoring and upper gastrointestinal hysterosalpingography.Those with any examinations being positive were brought into GERD group,and the others into the control group.All cases had been surveyed with GERD-Q.Using SPSS17.0 statistical software,the ratio was compared with chi-square test,and the difference of the scores between groups with t test.Results In infants (1 to 11 months),the individual symptom scores (ISS) of the 6 symptoms in the GERD group (n =111) were all higher than those in the control group (37 cases) (P ＜ 0.05),and the composite and symptom scores (CSS) [(131.43 ± 66.56) scores] in the GERD group was higher than that [(33.70 ± 40.03) scores] in the control group (t =8.42,P ＜ 0.05).In young children (1 to 3 years old),the ISS in the GERD group(55 cases) were all higher than those in the control group(32 cases),and the CSS[(98.58 ± 66.75) scores] in the GERD group was also higher than that [(28.50 ± 35.95) scores] in the control group(t =5.49,P ＜ 0.05).Conclusions There is a good correlation for age-specific GERD-Q to distinguish GERD symptoms in infants and young children,which is suitable for the assessment of GERD.

OBJECTIVE:To evaluate the inhibitory actions of 3 traditional Chinese drugs on human nasopharyngeal carcinoma cells CNE-2 in vitro.METHODS:The IC50(50% inhibiting concentration)of 3 traditional Chinese drugs on human nasopharyngeal carcinoma cells CNE-2 in vitro was measured by MTT assay.RESULTS:The inhibitory actions of 3 traditional Chinese drugs on human nasopharyngeal carcinoma cells CNE-2 in vitro were enhanced with the increase of the concentration in a concentration-dependent manner,with formulation Ⅲ showing the most potent inhibitory action on CNE-2 cells in vitro.CONCLUSION:The heat-clearing and detoxicating traditional Chinese drugs could markedly inhibit the proliferation of CNE-2 cells.

Objective To evaluate the development of immature oocytes after freezing-thawing by conventional cryopreservation method for mature oocytes.Methods Immature oocytes were collected from stimulated ovaries of intracytoplasmic sperm injection(ICSI)cycles.Immature oocytes were in vitro matured directly or after slow freezing-fast thawing and immunostained for tubulin and chromatin and at last visualized by confocal microscopy.Results No statistical difference was found in maturity rate between freezing groups and the controls.There was a statistically significant increase in abnormalities of chromosome(23.7% vs. 50%)and spindle(28.9% vs.53.9%)in the GV freezing group compared with the GV control(P

To study the application characteristics of copovidone (PVP-S630) in Xinyueshu extracts during the spray drying process, and its effect on such pharmaceutical properties as micromeritics and drug release behavior. PVP-S630 was added into Xinyueshu extracts to study on the spray drying, the effect of different dosages of PVP-S630 against the wall sticking effect of the spray drying, as well as the power property of Xinyueshu spray drying power and the dissolution in vitro behavior of the effective component of hyperoside. The results showed that PVP-S630 revealed a significant anti-wall sticking effect, with no notable change in the grain size of the spray drying power, increase in the fluidity, improvement in the moisture absorption and remarkable rise in the dissolution in vitro behavior of hyperoside. It was worth further studying the application of PVP-S630 in spray drying power of traditional Chinese medicine.
