Objective: To observe the clinical efficacy of lung-clearing and spleen-strengthening tuina on exogenous cough in children. Methods: A total of 77 children with exogenous cough that met the inclusion criteria were randomly divided into a treatment group and a control group according to the random number table, with 39 cases in the treatment group and 38 cases in the control group. The routine lung-clearing manipulation was used in the two groups, while the spleen- strengthening manipulation was added in the treatment group. Both groups were treated once a day, 5 times as a course of treatment. After one course of treatment, the symptom score and clinical efficacy were observed. Results: There were one dropout in the treatment group and 2 dropouts in the control group. Therefore, a total of 74 cases were finally included in the analysis, with 38 cases in the treatment group and 36 cases in the control group. After treatment, there was a statistically significant difference in cough score between the two groups (P<0.05). There was a statistically significant difference in the score of poor appetite between the two groups (P<0.05). After treatment, the total effective rate was 89.5％ in the treatment group versus 75.0％ in the control group, showing a statistically significant difference (P<0.05). Conclusion: The therapeutic efficacy of lung-clearing spleen-strengthening manipulation is better than that of lung-clearing tuina manipulation alone for children with exogenous cough; regulating spleen and stomach can improve the curative efficacy of exogenous cough in children.

Objective To study the changes of mesenteric arterioles on the contractile response to norepinephrine in patients with cirrhosis and portal hypertension (PHT) caused by hepatitis B after treatment by high-dose vitamin C.Methods Eleven PHT patients and 6 non-PHT volunteer were those undergoing their respective surgeriesat in our hospital from January 2010 to June 2011.The PHT patients were randomly assigned to vitamin C treatment group and placebo treatment group.After admission and before induction of anesthesia,blood taken to mesure plasma concentration of malonaldehyde (MDA).Intraoperative portal pressure was measured.We took the third level intestinal mesentery vessels with their mesentery next to the jejunum and studied the contractile response to norepinephrine of the intestinal mesenteric arterioles.We also measured RhoA/ROCK pathway associated proteins' expression and activity changes by Western-blot method.Results The average value of the plasma MDA of PHT patients with cirrhosis was much higher than that of non-PHT patients.After treatment by vitamin C,the value decreased.The dose-response curve of isolated mesenteric arterioles to norepinephrine from PHT patients with cirrhosis shifted to the right,and the EC50 value was higher than that of non-PHT patients.But this phenomenon was reversed after the patients treated with vitamin C.The protein expression of RhoA in mesenteric arteries did not change significantly among the three groups.But the protein expression and activity of ROCK-1 was significantly reduced in PHT patients with cirrhosis.After treatment with vitamin C,the expression and activity of ROCK-1 in mesenteric arteries of cirrhosis was significantly increased.Conclusion The PHT patients with cirrhosis are in the situation of oxidative stress.The high-dose vitamin C treatment can reduce oxidative stress level and improve contractile hyporeactivity of mesenteric arterioles of PHT patients with cirrhosis to norepinephrine.The protein expression and activity increasement of ROCK in RhoA/ ROCK pathway is involved in thisphenomenon.

Objective:To research the efficacy and adverse reactions of compound matrine injection combined with chemotherapy in the patients with advanced gastric cancer. Methods:According to the order of admission, 68 patients with advanced gastric cancer were divided into the observation group (34 cases) and the control group (34 cases). The two groups of patients were given chemo-therapy, and the observation group was treated with compound matrine injection additionally. After 3 months treatment, the curative effect and KPS score before and after the treatment were compared between the two groups. And adverse drug reactions were recorded for the two groups. Results:The total effective rate of the observation group (44. 12%) was significantly higher than that of the control group (20. 59%,P<0. 05). After the treatment, the KPS score of the observation group was significantly higher than that of the con-trol group (P<0. 05). The incidence of adverse drug reactions in the observation group was significantly lower than that in the control group (P<0. 05). Conclusion: The curative effect of compound matrine injection combined with chemotherapy for advanced gastric cancer is notable, which can significantly improve the KPS score and reduce the incidence of adverse reactions, and is worthy of promo-ted use in clinical practice.
