Objective To determine the content of ferulic acid, water and extract of Angelica formula particles, provide a reliable method for evaluation and quality control, and compare the quality of Angelica formula particles and Angelica pieces. Methods HPLC method was used with Kromasil C18 column (4.6 mm×250 mm, 5μm), flow rate of 1.0 mL/min, detection wavelength of 316 nm, column temperature at 28 ℃. The mobile phase was acetonitrile-0.05%phosphoric acid in water gradient elution system. Results Ferulic acid showed good linear relationship in the range of 0.033-0.165 μg (r=0.999 8). The average recovery was 98.78% and RSD=0.99%. Angelica formula particles met the quality requirement in the content indicators, the content of ferulic acid was higher than Angelica pieces. Conclusion The HPLC method for determination of ferulic acid in Angelica formula particles is simple and reliable, with good reproducibility, and can be used as the quality control method of Angelica formula particles.

Objective To explore the expression and localization of aquaporin 11(AQP11) in human term pregnancies with oligihydramnios, and its role in amniotic fluid balance.Methods We studied 55 patients who underwent elective cesarean sections, consisting of 25 patients with isolated oligohydramnios and 30 with normal amniotic fluid volume.Immunohistochemistry and reverse transcription polymerase chain reaction were employed to determine the expression and localization of AQP11 in the amnion, chorion and placenta.Results AQP11 protein was detected in expressed in the full-term pregnant women`s amnion, chorion and placenta.The expression in the amnion was positively correlated with amniotic fluid amount;the expression in the placenta was negatively correlated with amniotic fluid amount.The expression increased in the chorion with different amniotic fluid amount.Conclusion AQP11 plays an important role in regulating amniotic fluid balance.

Objective To observe the effect of modified SanJia-Fumai decoction with hormone replacement therapy on the endocrine and immune function of patients with climacteric syndrome. Methods A total of 84 patients with climacteric syndrome were divided into two groups according to the random number table, 42 cases in each group. The control group was treated with hormone replacement therapy. While the observation group was treated with modified Sanjia-Fumai decoction on the basis of the control grop. Both groups were treated for 4 weeks. The efficacy by scoring the changes of the patients clinical symptoms and signs was evaluated, and the serum hormones (LH, FSH, E2) levels were detected by radioimmunoassay, and the immune function index (CD3+, CD4+, CD8+) levels by immunofluorescence method, and the IL-2 by ELLSA. Results After treatment, the total efficiency of observation group was 92.8％ (39/42), while the control group was 73.8％ (31/42), and the difference was statistically significant (Z=-2.736, P=0.003). After treatment, the scores of hot flashes, menstrual disorders, insomnia and dreaminess, hot sweating, restlessness and dry mouth constipation in the observation group were significantly lower than those in the control group (t were 7.745, 10.364, 11.201, 16.765, 18.442, 18.625 respectively, P<0.001); the Serum LH and FSH levels in observation group were significantly lower than those in control group (t were 4.837, 5.016 respectively, P<0.01); the E2 level was significantly higher than that of control group (t=7.309, P<0.01). The levels of CD3+, CD4+, CD4+/CD8+, IL-2 in the observation group were significantly higher than those in the control group (t were 5.139, 6.083, 6.158, 5.932 respectively, P<0.01); The level of CD8+ was significantly lower than that of the control group (t=5.994, P<0.01). Conclusions The modified SanJia-Fumai decoction with hormone replacement therapy can regulate the endocrine function, improve the body's immunity and improve clinical symptoms of climacteric syndrome patients.

Objective To examine the prevalence ofHelicobacter pylori in Shanghai and relevant risk factors, evaluate the resistance proifle ofH. pylori isolates to antibiotics used in ifrst-line therapy in two hospitals in Shanghai.MethodsH. pylori were isolated from the biopsy samples of gastric mucosa collected from September 2013 to January 2015. Antimicrobial susceptibility test was performed by E-test method for 131H. pylori strains to 4 antibiotics, clarithromycin, metronidazole, amoxicillin and tetracycline. Results A total of 955 patients receiving gastroscopy were enrolled. And 248 (26.0%)H. pylori strains were isolated from the biopsy samples of gastric mucosa. Overall, 14.5%, 64.1%, 0 and 0.8% of the strains were resistant to clarithromycin, metronidazole, amoxicillin and tetracycline, respectively. Resistance to two drugs was found in 10.7%(14/131) of the strains, and majority (92.8%, 13/14) of which were resistant to clarithromycin and metronidazole.Conclusions The prevalence ofH. pylori in gastric mucosa is rather lower compared with the data reported previously. It is associated with the sex, age and clinical outcome of patients, however, antibiotic resistance profile is not related to these factors.H. pylori eradication therapy should be individualized according to the results of susceptibility test in Shanghai.
