Comparative efficacy and safety of Chinese patent medicines of iron deficiency anemia during pregnancy:A network meta-analysis

BACKGROUND Iron deficiency anemia(IDA)is a prevalent nutritional disorder during pregnancy.Clinical studies indicate that incorporating Chinese patent medicines(CPMs)with oral iron(OI)in treating IDA in pregnancy can reduce adverse effects and improve clinical outcomes.Nonetheless,the comparative efficacy of different CPMs remains unclear.AIM To assess the safety and effectiveness of different CPMs for treating IDA during pregnancy using network meta-analysis.METHODS We conducted a search for randomized controlled trials(RCTs)that combined CPM and OI for IDA treatment in pregnancy,spanning from 2013 to the present.Data analysis was performed using Rev Man 5.3 and Stata 14.0 on literature that satisfied the quality criteria.RESULTS The analysis included 45 RCTs,encompassing 4422 pregnant patients with IDA.Six CPMs were examined,including Shengxuebao Mixture,Shengxuening Tablets(SXN),Yiqi Weixue CPMs(YQWX),Jianpi Shengxue CPMs(JPSX),Yiqi Buxue Tablets,and Compound Hongyi Buxue Oral Liquid(FFHY).Findings indicated that FFHY+OI significantly improved the clinical effective rate.SXN+OI was most effective in boosting red blood cells counts and hemoglobin levels.YQWX+OI showed superior results in improving serum ferritin,and SXN+OI was most effective in increasing serum iron levels.JPSX+OI was optimal in reducing adverse pregnancy outcomes,while YQBX+OI effectively minimized adverse events.A cluster analysis suggested that SXN+OI could be the potentially optimal therapeutic regimen for IDA in pregnancy.CONCLUSION This study demonstrates that the combination of OI with CPMs offers better outcomes than OI alone.Based on clinical efficacy and other measured outcomes,SXN+OI emerges as the most effective treatment modality for improving the health of pregnant patients with IDA.

Effect of Western medicine therapy assisted by Ginkgo biloba tablet on vascular cognitive impairment of none dementia

Objective:To discuss the clinical effects of Western medicine therapy assisted by Ginkgo biloba tablet(GBT) on patients with vascular cognitive impairment of none dementia(VCIND).Methods: A total of 80 patients with VCIND were divided into two groups randomly:Conventional treatment group(control group) and combined treatment group.Conventional treatment group was given conventional treatment with anti-platelet aggregation.In this group,75 mg aspirin was given three times a day for 3 months.While in combined treatment group,19.2 mg CRT was given three times a day for 3 months together with conventional treatment(anti-platelet aggregation drugs). Montreal cognitive assessment(MoCA) and transcranial Doppler(TCD) were used to observe changes of cognitive ability and cerebral blood flow in VCIND patients before and after treatment in both groups.Then the clinical data were analyzed so as to compare the efficacy in two groups. Results:After 3 month-treatment in combined treatment group,the scores of executive ability, attention,abstract,delayed memory,orientation in the MoCA were significantly increased compared with those before treatment and those in control group after treatment.Besides,blood flow velocity of anterior cerebral artery increased significandy than that before treatment and that in control group after treatment.Conclusions:CBT tablet can improve the therapeutic efficacy as well improve cognitive ability and cerebral blood flow supply of patients with VCIND.

Clinical efficacy and safety of Guipi decoction combined with escitalopram oxalate tablets in patients with depression

BACKGROUND Depression is a widespread mental health condition that requires effective treatment.In the treatment of depression,traditional Chinese medicine(TCM)offers obvious advantages,fewer adverse reactions,and a lower recurrence rate.AIM To evaluate the clinical benefits of Guipi decoction combined with escitalopram oxalate tablets for individuals with depression.METHODS In total,80 patients diagnosed as having depression were enrolled in the study and divided into either an experimental group or a control group.All of the patients were orally administered escitalopram oxalate tablets.Additionally,the experimental group received Jiajian Guipi decoction and reduced Governor vessel fumigation over 4 wk.TCM syndrome scores,Hamilton depression rating scale(HAM-D)scores,self-rating depression scale(SDS)scores,and Pittsburgh sleep quality index scores were measured for the two groups and compared before and after the treatment.The two groups were monitored for any adverse reactions.RESULTS After 4 wk of treatment,both groups exhibited a significant reduction in TCM syndrome scores compared with their pre-treatment scores(P<0.05).However,the experimental group exhibited significantly lower TCM syndrome scores than the control group(P<0.05).Similarly,the post-treatment SDS and HAM-D-24 scores were significantly lower in both groups than the pre-treatment scores(P<0.05),with the experimental group exhibiting lower scores than the control group(P<0.05).The total treatment efficiency was significantly better in the experimental group(97.14%)than in the control group(77.78%)(P<0.05).Furthermore,after 4 wk of treatment,the Pittsburgh sleep quality index scores for both groups were significantly lower than those before the treatment(P<0.05),with the experimental group exhibiting lower scores than the control group(P<0.05).The incidence of adverse reactions was significantly lower in the experimental group than in the control group(P<0.05).CONCLUSION The combination of Guipi decoction and escitalopram oxalate tablets was found to be an effective and safe treatment for depression.This combination could reduce TCM syndrome scores,improve depressive symptoms,and enhance sleep quality.

The Determination of Surface Tension of Traditional Chinese Medicine Tablet

In this paper we aimed to determine the surface tension of traditional Chinese medicine (TCM) tablet and tried to provide a key reference parameter to control tablet film coating quality. Using contact angle tester, the Chinese medicine tablet, a famous Fufang Danshen tablet CP as a model example, was determined by Zisman critical surface tension method. Our study showed that the critical surface tension of Fufang Danshen tablet CP was determined to be 18.00 dyne/cm. The Zisman method, hence, can determine successfully the critical surface tension of Chinese medicine tablet and will become an effective manner to control tablet film coating quality.

多孔中药固体片剂孔隙率的太赫兹有效介质模型研究

目前对中药片剂的孔隙测量,一般采用的是具有破坏性的密度测量方法,缺乏无损量化方法。太赫兹辐射能用于无损的提取药物若干光学信息。针对直压型中药片剂,通过太赫兹时域和频域信号处理等不同方法分别计算各种片剂的有效折射率,发现两种方法得到的有效折射率和片剂的孔隙率均呈良好的线性关系。根据有效折射率特性,利用四种有效介质模型提取了中药片剂的孔隙率并进行量化回归,通过交叉验证与相对分析误差(RPD)发现通过时域信号处理的有效折射率得到的孔隙率回归模型解释性与验证准确性更高,其中最佳模型是Bruggeman模型(RPD=11.3325)。为中药多孔粉体制剂工艺优化提供支持。
