Objective To evaluate the efficacy and safety of Tongxiening granule （TXNG） in the treatment of diarrhea-predominant irritable bowel syndrome （IBS） （stagnation of the liver-qi attacking the spleen）. Methods In a prospective, randomized, placebo-controlled, double-blind clinical trial, 60 patients with diarrhea-predominant IBS were randomly divided into the TXNG group （TXNG, 5.0g, 3 times daily; n =30） and the placebo group （placebo, 5. 0g, 3 times daily; n =30）. The treatment was administered for 3 weeks, and the follow-up was conducted for 4 weeks.Results （1）Abdominal pain： The cure rates were 57. 7% vs. 16. 0% （ by per-protocol analysis, PP） and 31.0% vs. 7.1% （ by intention-to-treat analysis （ITT） ; and the overall improvement rates were 92.3% vs. 44.0% （PP） and 82.7% vs. 39.3% （ITT） in the TXNG and the placebo groups respectively （ P 〈0. 05）. （2） Diarrhea ： the cure rates were 46. 2% vs. 20. 0% （PP） and 41.4% vs. 17. 9% （ITT） , and the overall improvement rates were 96. 2% vs 48. 0% （PP） and 86. 2% vs 42.9% （ITT） in the two groups respectively （P 〈0.05）. （3）Traditional Chinese medicine symptoms： the cure rates were 30.8% vs. 4.0% （PP） and 27.6% vs. 3.6% （ITT） ; and the overall improevment rates were 92.3% vs. 48.0% （PP） and 82.7% vs 42.9% （ITT） in the two groups respectively （P 〈0. 05）. The pain duration after treatment in the TXNG group was significantly shortened compared with the placebo group （7.6 ±4. 6d vs 14. 4 ±4. 3d, P =0. 0125）. After 4-week follow-up, it suggested that the recrudescent duration in symptoms related to IBS in the TXNG group was longer than that in the placebo group （11.5 ±5.3 d vs 6.2 ±6.9 d, P = 0. 019）. No adverse effects were found in the TXNG group. Conclusion It was demonstrated that TXNG is effective and safe in the treatment of diarrhea-predominant ms （stagnation of the liver-qi attacking the spleen）.
Objective To assess the effectiveness and safety of prulifloxacin in the treatment of urinary tract infection. Methods The double-blind, double dummy and randomized controlled method was adopted. One hundred and forty-four patients were randomized to the treatment group (prulifloxacin , 4 tablets, bid) and the control group (levofloxacin, 4 tablets, bid). The randomization code was produced by computer. The treatment duration for both groups was from 7 to 10 days. Results Data were analyzed on the basis of full analysis sets (FAS) and per-protocol (PP) analysis. The total improvement rates of the trial and control groups were 85.07% and 88.52% respectively by FAS analysis, and 90.48% and 91.53% respectively by PP analysis. There was no significant difference between the two groups in improvement rates (Pgt;0.05). Bacterial negative rates in the trial and control groups were 93.75% and 93.88% respectively by FAS analysis and 97.83% and 97.87% respectively by PP analysis. The results showed no statistical significance difference between the two groups in bacterial negative rates (Pgt;0.05). The adverse events in the prulifloxacin and levofloxacin groups were 2.80% and 5.60% respectively. Conclusion Prulifloxacin has the same clinical effectiveness as levofloxacin with a few toxic adverse effects in the treatment of urinary tract infection.
Objective To evaluate the safety and efficacy of Jinlianqingre capsule in treatment of acute upper respiratory tract infection （external wind-heat syndrome）. Methods A multi center, double-blind, double dummy, randomized controlled trial was conducted. A total of 226 patients with acute upper respiratory tract infection were randomized into two groups：the trial group （116 patients）received Jinlianqingre capsule and the control group （110 patients） received Jinlianqingre granule. The therapeutic courses of both groups were 3 days. Results The total significant effective rates and the total effective rates of acute upper respiratory tract infection were 66.38 % and 95.69% in the trial group respectively, and 60.91% and 95.45% in the control group respectively. There were no statistical differences between the two groups （P 〉0.05）. The total significant effective rates and the total effective rates of Chinese medicine symptoms were 70.69% and 97.41% in the trial group respectively, and 69.09% and 93.64% in the control group respectively. There were no statistical differences between the two groups （P 〉0.05）. Besides, the efficacy of Jinlianqingre capsule was better than that of Jinlianqingre granule with respect to fever duration after treatment; there were statistical differences between the two groups （P〈0. 05 ）. No adverse effects were found in the trial group. Conclusions Jinlianqingre capsule is effective and safe in treatment of acute upper respiratory tract infection （external wind-heat syndrome）.
Objective To assess the effectiveness and safety of Jiuweirougan granule in the treatment of chronic hepatitis with hepatic fibrosis. Methods A double-blind, double dummy and randomized controlled method was adopted. Forty-six patients were selected by using the inclusion and exclusion criteria and were randomizedly allocated to the treatment group (n=23, Jiuweirougan 10 g, twice a day) and the control group (n=23, treated with Biejiaruangan 4 pills, three times a day). The duration of treatment for both groups lasted for 6 months. Results Two patients in the treatment group dropped out halfway through the study, while one patient in the control group was withdrawal for irregular treatment. Analysis according to intention-to-treat (ITT) and per-protocol (PP) was conducted. In the treatment group, the effective rates of TCM (Traditional Chinese Medicine) on the syndrome were 82.61% (19/23) (ITT) and 90.48% (19/21) (PP), while in the control group, there were 86.96% (20/23) (ITT) and 86.36% (19/20) (PP). There was no significant difference between the two groups (P＞0.05). The improvement rate of serum parameters in the treatment group such as hyaluronic acid (HA), type Ⅲ procollagen (PCⅢ), type Ⅳ collagewn (CⅣ) and laminin (LN) were 28.57% (6/21), 23.81% (5/21), 28.57% (6/21) and 4.76% (1/21), respectively, while in control group, the rates were 36.37% (8/22),13.64% (3/22), 36.37% (8/22) and 9.09% (2/22), respectively. No significant difference was seen between the two groups (P＞0.05). ITT and PP analysis revealed similar results. No obvious adverse effects were noted. Conclusion Jiuweirougan granule may improve chronic hepatitis with fibrosis, and its effect is equal to that of Biejiaruangan. No obvious toxic-adverse effects were seen.
Objective To assess the effect and safety of Dalitong Granule in the treatment of the Piman syndrome (functional dyspepsia). Method The double-blind, double-dummy and randomized controlled method was adopted. 120 patients were randomized to the treatment group (n=90, Dalitong Granule 6 g, tid) and the control group (n=30, treated with cisapride 5 mg, tid). The therapeutic course for both groups was 2 weeks. Results All the results were analyzed on the basis of intention-to-treat and per-protocol population. In the treatment group, the markedly effective rates were 62.37% and 64.45% respectively. The effective rates were 99.55% and 96-67% respectively. In the control group, the markedly effective rates were 58-08% and 60.00% respectively. The effective rates were 90.33% and 93.33% respectively. There was no significant difference between two groups (Pgt;0.05). For effects on Piman syndrome, in the treatment group, the markedly effective rates were 53.76% and 55.56% respectively. The effective rates were 86.02% and 88.89% respectively. In the control group, the markedly effective rates were 48.38% and 50.00% respectively. The effective rates were 80.64% and 83.33% respectively. The results showed no statistical significance difference between two groups (Pgt;0.05). For effects on gastric emptying function (PP population), in the treatment group, the markedly effective rate and effective rate were 72.42% and 79.32%. In the control group those were 64.28% and 64.28%. There was no significant difference between the two groups (Pgt;0.05). ITT and PP analysis revealed similar results. No adverse effect was found in the observation. Conclusions Dalitong granule has the same clinical effect as cisapride with no obvious toxic-adverse effects.
