Historical Evolution and Modern Research Progress of Processing of Scutellariae Radix / 中国实验方剂学杂志

By consulting ancient herbal books and modern literature， this paper systematically sorted out and researched the processing history， relevant processing norms in recent years， modern processing technology， chemical composition changes of processed products and their pharmacological mechanism of Scutellariae Radix， in order to provide a basis for the further development of Scutellariae Radix decoction pieces. According to the textual research of ancient books， there were many kinds of processing auxiliary materials of Scutellariae Radix， such as wine， vinegar， salt， honey， pig bile and so on， among which the wine processing was the most diverse and detailed， and the processed products such as raw products， stir-fried products， wine-processed products， fried charcoal products were still in use. The modern processing techniques of Scutellariae Radix mainly focus on the processing aspects of softening and slicing， wine processing and charcoal frying， and the research methods are relatively unified. At present， it is found that the changed chemical constituents of Scutellariae Radix after processing are flavonoids， polysaccharides， volatile oils and trace elements， etc. Pharmacological effects of processed products are hemostasis， antibacterial， anti-inflammatory， antioxidant， analgesic and antipyretic， treatment of lung diseases， treatment of colitis， etc. However， in the studies of Scutellariae Radix processing， there is a lack of research on the structural changes of chemical components caused by processing and a comprehensive comparative study on the pharmacological effects of various processed products. Based on this， it is suggested to carry out systematic research on the processing technology to processing mechanism， further explore the relationship between the change rule of material basis and pharmacological action before and after processing of Scutellariae Radix， and deepen the exploration of molecular mechanism and clinical application of processed products of Scutellariae Radix， in order to clarify the scientific connotation of the processing mechanism of Scutellariae Radix， and lay a foundation for the subsequent expansion of the application of Scutellariae Radix decoction pieces and the formulation of processing standards.

Tongjiang granule intervened non-erosive reflux disease patients of Gan-Wei incoordination syndrome: a curative effect observation / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To assess the effectiveness of Tongjiang Granule (TJG) in treating non-erosive reflux disease (NERD) of Gan-Wei incoordination syndrome (GWIS).</p><p><b>METHODS</b>Totally 128 NERD patients of GWIS were recruited from outpatients or inpatients at Department of Digestive Disease, Xiyuan Hospital, China Academy of Chinese Medical Sciences from February 2009 to November 2010. They were randomly assigned to two groups using the block group in the ratio of 1:1, 64 cases in each group. Patients in the experiment group were treated with TJG, 10 g each time, three times a day, while those in the control group were treated with Omeprazole Tablet, 20 mg each time, two times a day. The treatment course of both groups was 4 weeks. The symptoms questionnaires and SF-36 quality of life scale were observed.</p><p><b>RESULTS</b>Finally 114 patients completed the trial. There was statistical difference in epigastric upset, pharyngeal foreign body sensation, abdominal swelling or abdominal pain, and integral of excrement between the two groups before treatment (P < 0.05). However, there was no statistical difference in the rest indices between the two groups (P > 0.05). Compared with before treatment in the same group, the scores of each symptom or the total symptoms were somewhat improved in the two groups (P < 0.01, P < 0.05). There was statistical difference in the rest scores (P > 0.05) except the score of mental health in the experiment group (P < 0.01, P < 0.05). There was statistical difference in the rest scores (P > 0.05) except the score of physical function in the control group (P < 0.01, P < 0.05). There was statistical difference in post-treatment acid reflux, irritability, depression, body pain, roles of emotions (P < 0.01, P < 0.05). The total effective rate was higher in the experimental group, showing no statistical difference when compared with that of the control group (P > 0.05).</p><p><b>CONCLUSIONS</b>TJG had confirmative efficacy in treating NERD patients of GWIS. Meanwhile, it could improve their quality of life, with no obvious adverse reaction.</p>

Evaluation of balanced release of complex components of Chuanping sustained tablets based on fingerprint / 中国中药杂志

To combine fingerprint and drug release rate in vitro, in order to study in vitro release of complex components of Chuanping sustained tablets, compound traditional Chinese medicine preparation. A qualitative determination of the characteristic peaks of the compound preparations were conducted by the fingerprint. The results of the dissolution rate determination under different release conditions showed that the release of three index components (methamphetamine, pseudoephedrine and scopolamine) of Chuanping sustained tablets was less affected by gastrointestinal factors, with similarity factors being more than 80 with unknown component release curves of three major characteristic peaks in the fingerprint. The qualitative determination proved that multiple components of the compound traditional Chinese medicine preparation was dissolved in vitro at similar rates, realizing the balanced release of complex components of the compound traditional Chinese medicine preparation. This study layed a theoretical and experimental basis for quality evaluation for the compound traditional Chinese medicine preparation.

Analysis of rational clinical uses of traditional Chinese medicine injections and factors influencing adverse drug reactions / 中国中药杂志

<p><b>OBJECTIVE</b>To rationalize the clinical use and safety are some of the key issues in the surveillance of traditional Chinese medicine injections (TCMIs).</p><p><b>METHOD</b>In this 2011 study, 240 medical records of patients who had been discharged following treatment with TCMIs between 1 and 12 month previously were randomly selected from hospital records. Consistency between clinical use and the description of TCMIs was evaluated. Research on drug use and adverse drug reactions/events using logistic regression analysis was carried out.</p><p><b>RESULT</b>There was poor consistency between clinical use and best practice advised in manuals on TCMIs. Over-dosage and overly concentrated administration of TCMIs occurred, with the outcome of modifying properties of the blood. Logistic regression analysis showed that, drug concentration was a valid predictor for both adverse drug reactions/events and benefits associated with TCMIs.</p><p><b>CONCLUSION</b>Surveillance of rational clinical use and safety of TCMIs finds that clinical use should be consistent with technical drug manual specifications, and drug use should draw on multi-layered logistic regression analysis research to help avoid adverse drug reactions/events.</p>

Transcutaneous electrical nerve stimulation on acupoints relieves labor pain: a non-randomized controlled study / 中国结合医学杂志

<p><b>OBJECTIVE</b>To investigate the efficacy of transcutaneous electrical nerve stimulation (TENS) on four specific acupuncture points Hegu (LI4), Neiguan (PC6), Danshu (BL19) and Weishu (BL21) for reducing pain in labor.</p><p><b>METHODS</b>A total of 160 voluntary nulliparous women who were willing to receive TENS for analgesia were assigned to the treatment group after cervical dilation of more than 2 cm. Another 145 matched nullipara were recruited as the control group. Visual analogue scale (VAS) was used to assess the pain before and 0.5 h after the application of TENS. Then, VAS was assessed every one hour until delivery. Percentage of VAS score decreased by > 25% was the primary outcome, the delivery mode and neonatal outcome were measured as secondary outcomes. Adverse reactions were also recorded during TENS.</p><p><b>RESULTS</b>The percentage of VAS score decreased by > 25% was 68.6% in the TENS treatment group. Maternal delivery mode and neonatal outcomes were not significantly different between the two groups. In addition, the incidence of postpartum hemorrhage in the TENS treatment group was less than the control group (P<0.05). There was no adverse reaction recorded with TENS on acupoints.</p><p><b>CONCLUSION</b>As a novel and non-invasive approach, TENS on specific acupoints including Hegu (LI4), Neiguan (PC6), Danshu (BL19) and Weishu (BL21) was an effective method for analgesia in labor.</p>
