[Quality standard and quality value transfer of reference samples of classical prescription Huagan Decoction].

The detection method of characteristic spectrum for reference samples was established by preparing 15 batches of the reference samples of Huagan Decoction, and the peak attribution and the similarity range in the characteristic spectrum were clarified. The ranges of paste-forming rate, content, and transfer rate of the index components including geniposide, paeonol, and paeoniflorin were analyzed. The key quality attribute of the reference samples of Huagan Decoction was defined. The results showed that the 15 batches of the reference samples of Huagan Decoction had good similarities in the characteristic spectrum, which were all higher than 0.9. According to the information of characteristic peak, there were 18 characteristic peaks in the whole prescription, including seven common characteristic peaks from green tangerine peel and dried tangerine peel, four characteristic peaks from tree peony root bark(three of them were common characteristic peaks from tree peony root bark and red peony root), five characteristic peaks from cape jasmine fruit, one characteristic peak from paniculate bolbostemma, and one characteristic peak from oriental waterplantain rhizome.The paste-forming rate of the 15 batches of reference samples was 14.73%-18.83%. The content of geniposide was 1.68%-2.87%, with the average transfer rate of 70.05%±11.13%. The content of paeonol was 0.10%-0.16%, with the average transfer rate of 9.38%±1.78%. The content of paeoniflorin was 1.94%-2.74%, with the average transfer rate of 36.69%±4.63%. This study analyzed the quality value transfer of the reference samples of Huagan Decoction by the evaluation mode of combining the characteristic spectrum, the paste-forming rate, and the content of index components.

[Advances of researches on peripheral PKCε pathway during transformation from acute to chronic pain and possibility of application of electroacupuncture intervention].

Protein kinase Cε (PKCε) is a transforming oncogene and plays an important role in many cellular processing. In the present paper, we review the development of experimental researches on the acute-chronic pain transformation. Results indicated that prostaglandin E2 (PGE2) / EP1 receptor-Gq-PKCε is an important signaling pathway to modulate chronic pain in peripheral dorsal root ganglion (DRG) neurons, and also plays a role in the later stage of hyperalgesia during transformation from acute to chronic pain. PKCε in DRG neurons induces mechanical and thermal hypersensitivity respectively by over expression of transient receptor potential vanilloid 1 (TRPV1) and TRP ankyrin-1 (TRPA1), further mediating the transformation from acute to chronic pain. Whereas, PGE2-evoked activation of EP1-Gq-PKCε signaling may be the key link in initiating the pain translation process through regulating downstream TRPA1 and TRPV1. Electroacupuncture (EA) has been used to effectively relieving various types of acute and chronic pain for decades, and can significantly inhibit the expression of PKCε and its upstream and downstream molecules. Therefore, it can be inferred that there exists a possibility of EA interventions in interfering the transformation from acute to chronic pain by regulating peripheral PKCε signaling pathway.

Research on Development of Preparations in Traditional Chinese Medicine Classics During the Han,Tang and Song Dynasties / 中国实验方剂学杂志

This paper compared and analyzed the relevant records of Chinese medicine pharmacy in the Han,Tang and Song dynasties,and summarized the changes of the dosage forms,preparation techniques and administration methods of Chinese medicine with the development of history.In this study,three classic medical works in the Han,Tang and Song dynasties,including Treatise on Febrile Diseases Caused by Cold,Valuable Prescriptions for Emergency and Formularies of the Bureau of People's Welfare Pharmacies,were taken as the research objects,and the development of the dosage forms,auxiliary materials,preparation technology and medication theory were summarized and explored by the ways of content analysis,comparative analysis and case analysis.The comparison showed that in the development process,the dosage forms gradually increased,but the liquid dosage forms gradually decreased,the solid dosage forms gradually increased.Not only the dosage forms varied in the number,types of excipients used more and more,but the level of preparation had been constantly improved while the methods of taking became more detailed.This evolution of dosage forms and pharmaceutical technologies in Chinese history is worth learning and thinking about it.Through exploring the traditional Chinese medicine(TCM) technologies and theories in the Han,Tang and Song dynasties,we can contribute to the inheritance of traditional preparations and it can provide the basis for the development of modern preparations with TCM characteristics.

[Effect of Electroacupuncture on Pain Transition and Content of Protein Kinase Cε in Dorsal Root Ganglia in Hyperalgesia Rats].

OBJECTIVE: To observe the effect of electroacupuncture (EA)on mechanical pain transition and content of protein kinase C epsilon(PKCε)in dorsal root ganglia (DRG) in inflammatory articular pain rats，so as to explore its peripheral mechanism underlying relieving transition from acute to chronic pain. METHODS: 1)In the first part of the present study，male SD rats were equally randomized into blank control，sham hyperalgesic priming(HP), and real HP groups(n＝6 in each). The HP model was established by subcutaneous injection of 1% carrageenan (100 µL) into the left hind paw (the first injection)，followed by injection of PGE 2 (100 ng/25 µL, the second injection) into the dorsum pedis of the same hind paw 7 days after the first injection. The mechanical withdrawal threshold (MWT) of the ipsilateral paw was detected before and 4, 24, 48, 72 h, and 7 d after the first injection，and 1, 4, 24 and 48 h after the second injection. 2) In the second part，SD rats were randomly divided into sham-HP，real HP，sham-EA and EA groups(n＝6 in each). The sham-HP and HP models were made in the same way as those in the first part. Bilateral "Zusanli"(ST 36)and "Kunlun"(BL 60)were punctured with filiform needles and also stimulated with electrical current：2 Hz/100 Hz，0.5－1.5 mA(0.5 mA increase per 10 min)for 30 min，1 time/d from the 1st carrageenan injection on till the end of the experiments. PKCε protein expression in the L 4－L 6 DRGs was assayed by Western blot 48 h after the second injection. RESULTS: 1)In the first part of the study，compared with the sham-HP group，the MWT at 4, 24、48 h after carrageenan injection and 4, 24 and 48 h after PGE 2 injection were significantly decreased in the HP model group(P<0.01). 2)In the second part，compared with the HP group，the MWT at 24、48 and 72 h after carrageenan injection, and 24 and 48 h after PGE 2 injection were significantly up-regulated in the EA group(P<0.05，P<0.01). 3)The relative content of PKCε in the DRGs(L 4－L 6)was significantly higher in the HP group than in the sham-HP group(P<0.01)，but considerably lower in the EA group than in the HP group (P<0.01)．. CONCLUSION: EA has a good effect on pain conversion in inflammatory joint pain rats，which may be related to its effect in down-regulating the PKCε level in the ipsilateral lumbar DRGs.

Effects of Jianpisanjie pills on the gastro-intestinal functions / 中国药学杂志

OBJECTIVE: To investigate the effects of Jianpisanjie (JPSJ) pills on the gastro-intestinal functions by animal experiment. METHODS: With gastric evacuation and gastrointestinal propulsion movement of mice obstructed by atropine sulphate, and the emesis of pigeon resulted by copper sulfate, the effects of JPSJ on gastrointestinal function was investigated, the effects on vomit latent period and emesis times were also studied. The model of hepatoma H22 bearing mice was established. After weighting, the mice were randomized into 5 groups, they were the control group, the high, middle, low dosages of JPSJ, and the positive-control group. Then they were treated with chemotherapy and administrated with subject drugs. When the trial ended, the weight and food intake of H22 bearing tumor were determined. RESULTS: Different dosage of JPSJ could increase the gastric evacuation rate and gastrointestinal propulsion rate, prolong the vomit latent period and emesis times of pigeon. And the pills also could reduce the side-effects of chemotherapy, such as weight of mice and food intake. CONCLUSION: JPSJ could promote the gastro-intestinal function, improve the weight loss and less food intake resulted by chemotherapy, and may be adjuvant drug for tumor.

[Observation on clinical effects of moxibustion stimulation of different sensitive status acupoints for knee osteoarthritis].

OBJECTIVE: To observe the clinical effect of moxibustion of different acupoints undergoing heat-sensitive state and resting state in the treatment of knee osteoarthritis (KOA) patients. METHODS: A total of 60 cases of KOA patients were enrolled in the present trial. They were divided into heat-sensitive moxibustion (heat-sensitive) group and non-sensitive moxibustion group (resting group). Moxibustion was applied to Neixiyan (EX-LE 4), Waixiyan (i.e. Dubi, ST 35) and Heding (EX-LE 2) for about 45 min, once daily for 20 days. The heat-sensitive state was evaluated according to the patient's feeling. After moxibustion stimulation at the acupoint area, if the patient feels the heat penetrating from the skin surface to the deep tissue, or/and extending peripherally around the moxibustion site, or/and transmitting toward a certain direction, it is considered to be heat sensitization state. The therapeutic effect was evaluated by using visual analogue scale (VAS) for pain severity changes and by Guiding Principles for Clinical Trials of New Drugs of Chinese Materia Medica for evaluating functional activity of the knee-joint. RESULTS: After 20 sessions of treatment and after a half year's follow-up, the total integrated scores of VAS in the heat-sensitive group were all lower than those of the resting group (P < 0.01). Following 20 sessions of treatment, of the two 30 KOA patients in the heat-sensitive group and resting group, 14 (46.67% )and 5 (16.67%) experienced a marked improvement, 10 (33.33%) and 9 (30.00%) were effective, 6 (20.00%) and 16 (53.33%) were invalid, with the effective rates being 80.00% and 46.67 , respectively. Half-year's follow-up showed that the effective rates of the heat-sensitive group and resting group were 79.17% (19/24) and 42.86% (6/14), respectively, suggesting a better therapeutic effect of heat-sensitive moxibustion. CONCLUSION: The clinicaln effect of heat-sensitive moxibustion is significantly superior to that of non-sensitive moxibustion in the treatment of KOA patients, being worthy of clinical application.
