ObjectiveTo study the effect of Shenling Baizhusan on electrogastrogram in children with spleen deficiency diarrhea. To clarify the occurrence of gastric electrical rhythm disorder in children with this disease， and to study whether Shenling Baizhusan can improve the abnormal gastric motility in children with diarrhea （spleen deficiency） MethodA total of 125 children with spleen deficiency diarrhea in the outpatient department of Children's Hospital of Shanghai from October 2019 to March 2021 were selected as the research objects， and they were randomly divided into a control group （60 cases） and an observation group （65 cases）. The children in the control group were treated with Montmorillonite powder combined with probiotics treatment， and the children in the observation group were additionally treated with Shenling Baizhusan. The course of treatment for both groups was 1 week. The clinical efficacy of the two groups of children after treatment and the scores of main traditional Chinese medcine（TCM） symptoms before and after treatment were compared， and the changes in the main parameters of electrogastrogram in children before and after treatment were compared. ResultAfter treatment， the total effective rate of observation group （90.77%， 59/65） was higher than that of control group （76.67%，46/60） （χ2=4.617， P<0.05）. After treatment， scores of fecal morphology， frequency of defecation， fatigue， inappetence， and other symptoms in both groups were lower than that before treatment （P<0.05）， and the observation group was lower than the control group （P<0.05）. As compared with before treatment， the main frequency， the percentage of normal slow wave， and the percentage of normal gastric electrical rhythm in the two groups increased after treatment （P<0.05）， and the control group was lower than the observation group （P<0.05）. The proportion of children with slow gastric rhythm decreased （P<0.05） as compared with before treatment， and the control group was higher than the observation group （P<0.05）. ConclusionShenling Baizhusan can significantly relieve the diarrhea symptoms in children with spleen deficiency diarrhea and improve gastric motility with good clinical effects.

Clinical Randomized Controlled Observation of Modified Wuhutang in Treatment of Acute Asthma in Children / 中国实验方剂学杂志

ObjectiveTo explore the clinical effect of modified Wuhutang in the treatment of children with acute asthma. MethodA total of 130 children with acute asthma were randomly divided into an observation group and a control group， with 65 cases in each group. The observation group was treated with modified Wuhutang and the control group was treated with procaterol hydrochloride for one week. The scores of primary symptoms （wheezing， cough， shortness of breath， and chest tightness） and secondary symptoms （mental status， runny nose， dry mouth， tongue texture， tongue coating， stool， etc.）， lung functions， immunoglobulin E （IgE） expression， eosinophil （EOS） count， and serum inflammatory factors， including interleukin （IL）-5， IL-6， IL-8， and IL-1β in two groups before and after treatment were compared. ResultThe data of 126 children were statistically analyzed. As revealed by the results， compared with the conditions before treatment， the scores of primary symptoms and secondary symptoms， serum levels of IL， IgE expression， and EOS count were both reduced in two groups （P<0.05）， lung functions were increased in the two groups（P<0.05）. Compared with the control group after treatment， the observation group showed decreased scores of cough and secondary symptoms （P<0.05）， and insignificant decrease in IL-1β （P<0.05）. The improvement in lung functions， IgE expression， and EOS count in observation group was equivalent to that in control group. ConclusionModified Wuhutang for treatment of acute asthma in children （phlegm-heat obstructing lung syndrome） can significantly relieve the clinical symptoms， improve lung functions， and reduce IgE， IL-5， IL-6， IL-8， IL-1β expression levels and EOS count， and its overall clinical efficacy is superior or equivalent to that of tprocaterol hydrochloride.

Aggravated airway inflammation and resistance in a respiratory syncytial virus infected murine asthma model / 第二军医大学学报

Objective To explore the role of…respiratory, syncytial virus (RSV) infection in aggravating airway inflammation and airway resistance in murine-asthma model. Methods A total of 30 6-8-week-old male BALB/c mice were equally divided into three groups randomly: thecontrol group,’ ovalbumin (OVA) group (asthma group), and respiratory syncytial virus (RSV)/OVA group (RSVh asthma group). In OVA group,murine asthma model was established using an OVA sensitization; in OSV/RSV group,mice were firstly sensitized by OVA and subsequently infected with RSV intranasally for three times to make acute viral infection asthma model ; and in control group, the mice received equal volume of PBS treatment. Twenty-four hours after the last challenge,the airway resistance was evaluated by mouse ventilator (Buxco RC). Inflammatory cell infiltration was measured in bronchoalveolar lavage fluid (BALF). Pulmonary tissue samples were collected and stained with H E,PAS or VG to observe inflammation of pulmonary tissues. Results Pulmonary tissue of mice in OVA group had inflammatory cell infiltration, airway mucus secretions were visible, and collagen was seen around the airway. Pulmonary tissue of mice in OVA/RSV group had significant inflammatory cell infiltration, alveolar stenosis, telangiectasia congestion,airway mucus secretions and collagen deposition. Lung function and the proportion of BALF eosinophils (EOS%) in OVA group and OVA/RSV group were significantly different from that of the control group (P<0. 05,7<0. 01). Airway resistance and the EOS% in OVA/RSV group were significantly different from those of the OVA group (P<0. 05). Conclusion RSV infection can aggravate the airway inflammation and result in airway resistance in murine asthma model.

Efficacy and safety of the combined oral contraceptive ethinylestradiol/drospirenone (Yasmin) in healthy Chinese women: a randomized, open-label, controlled, multicentre trial.

To evaluate and compare the contraceptive efficacy, bleeding pattern, side effects and other positive effects of a combined oral contraceptive (COC) containing drospirenone (DRSP) [Yasmin] with those of a COC containing desogestrel (DSG) in healthy Chinese women. This was a randomized, open-label, controlled, multicentre study of 768 healthy Chinese women requiring contraception. The subjects were randomized to ethinylestradiol (EE) 30 microg/DRSP 3 mg (n = 573) or EE 30 microg/ DSG 150 microg (n = 195), at a ratio of 3 : 1. Each individual was treated for 13 cycles. Further visits were required at cycle 4, cycle 7, cycle 10 and cycle 13 of treatment. Weight, height and body mass index were evaluated at each visit. The Menstrual Distress Questionnaire (MDQ) was administered at baseline, visit 3 (cycle 7) and visit 5 (after cycle 13). Baseline characteristics were similar between the two groups (p > 0.05). The Pearl Index (method failure) for EE/DRSP was 0.208 per 100 women-years, which was lower than that for EE/DSG (0.601 per 100 women-years). There were no significant differences between the treatment groups with regard to bleeding patterns. According to the MDQ subscale, improvements in water retention and increases in appetite during the intermenstrual period and in water retention and general well-being during the menstrual period in the EE/DRSP group (-0.297, -0.057, 0.033 and 0.150, respectively) were significantly improved compared with the EE/DSG group (-0.108, 0.023, 0.231 and -0.023, respectively) [all p < 0.05]. Other values that improved in both groups, particularly improvement in breast pain and tenderness and skin condition, were more evident in the EE/DRSP group (18.0%, 89/494; 12.6%, 62/494) than in the EE/DSG group (11.3%, 19/168; 5.4%, 9/168). Mean weight increased in the EE/DSG group (0.57 kg) while there was a significant decrease in mean weight (-0.28 kg) in the EE/DRSP group (p < 0.01). Both EE/DRSP and EE/DSG have good contraceptive efficacy and a comparable bleeding pattern. EE/DRSP had a more favourable effect on weight and premenstrual symptoms than EE/DSG.

Conception probabilities at different days of menstrual cycle in Chinese women.

OBJECTIVE: To investigate the conception probability among Chinese women. DESIGN: Prospective observational study. SETTING: Clinics in hospitals and family planning institutes in 10 provinces and cities. PATIENT(S): A total of 851 healthy married women aged 18-35 years with normal menstrual cycles who wish to have babies and with no contraception. INTERVENTION(S): Urinary LH was measured around days of expected ovulation for 7 days. The Barrett and Marshall model was used for calculation of conception probabilities on each cycle day from day -5 to day +1 in women with multiple episodes of intercourse. MAIN OUTCOME MEASURE(S): Pregnancies in 1, 3, and >or=6 months. RESULT(S): A total of 851 women with 2,055 cycles were analyzed. In 489 cycles there was only one episode of intercourse. A total of 601 pregnancies occurred. The conception probabilities from days in relation to ovulation -5 to +1 for a single episode of intercourse were 0.216, 0.102, 0.236, 0.233, 0.388, 0.293, and 0.386, respectively, and for multiple episodes they were 0.254, 0.271, 0.293, 0.365, 0.315, and 0.284, respectively, with the peak value at day -1. Recalculation of the efficacy of emergency contraception with low-dose mifepristone with the present conception probabilities showed higher efficacy. CONCLUSION(S): Conception probabilities among Chinese women are different from those in the literature. Further comparative studies are needed to confirm an ethnic difference.
