Objective To observe the effect of acupoint thread-embedding at Neiguan (PC6) and Zusanli (ST36) on anxiety and sleep disorders after heroin withdrawal. Method Sixty-seven patients with heroin addiction were randomized into a Neiguan group (25 cases), a Zusanli group (22 cases) and a Neiguan plus Zusanli group (20 cases), to receive corresponding treatments once every 20 d, for 4 sessions in total. The Self-rating Anxiety Scale (SAS) and Pittsburgh Sleep Quality Index (PSQI) were adopted to observe the anxiety and sleep condition before and after the treatment. Result After 60 d thread-embedding treatment, the total and standard SAS scores, sleep initiation time and total PSQI score were significantly decreased in the 3 groups (P<0.05), and the sleep durations were significantly extended (P<0.05); in comparing the improvement of anxiety, Neiguan plus Zusanli group > Neiguan group >Zusanli group (P<0.05); in comparing the improvement of sleep, Neiguan plus Zusanli group was superior to both Zusanli group and Neiguan group (P<0.05), while there was no significant difference between Zusanli group and Neiguan group (P>0.05). Conclusion It's effective to use thread-embedding at Neiguan and Zusanli independently or together for anxiety and sleep disorders after heroin withdrawal, but the efficacy is more significant when the two points are used in combination, indicating the synergy of acupoints.

In order to study the analgesic effect of Shaoyao Gancao Decoction, this paper discussed material basis and mechanism from the perspective of macromolecules in traditional Chinese medicine. Inspired by the phenomenon of turbidity after boiling Chinese medicine, this experiment took Shaoyao Gancao Decoction as the research object to study the formation process of precipitation during boiling. The results showed that aggregates with a certain shape were formed in the solvent during the boiling process, and the precipitate was obtained by standing and centrifuging. Analysis found that the precipitation was mainly composed of small molecules such as paeoniflorin, albiflorin, liquiritin, glycyrrhizic acid, isoliquiritin and gallic acid, and macromolecules such as protein and polysaccharide. The composition of precipitate was consistent with that of Shaoyao Gancao Decoction, but the analgesic effect of Shaoyao Gancao Decoction after removing the precipitate was significantly reduced. Based on these results, we isolated small molecular compounds, polysaccharides and protein from Shaoyao Gancao Decoction and their contents are 60.4, 700.7 and 207.2 mg·g^-1 respectively. We get the ratio, polysaccharide: small molecule = 11.6∶1, protein: small molecule = 3.4∶1, the precipitate is prepared in the state of boiling. The characterization results showed that the particle size of the precipitate will change significantly after co-heating, and the content determination results showed that the content of the six small molecular compounds which was free in solvent was significantly reduced after the formation of the precipitate. The acetic acid writhing experiment proved that the precipitate has a good analgesic effect, and effectively reduced the levels of inflammatory factors prostaglandin E2 and nitric oxide, and increased the level of anti-inflammatory factor interleukin-10. These results proved that the precipitate in Shaoyao Gancao Decoction is an important material basis for analgesic effect, and macromolecules such as protein and polysaccharide are the main components of the precipitate. The study of macromolecules in the precipitate of Shaoyao Gancao Decoction not only provides new ideas and methods for elucidating the pharmacodynamic material basis of Shaoyao Gancao Decoction, but also provides a reference for analyzing the scientificity of traditional decoction.

Rotavirus capsid protein Vp4 plays an important role in the virus adhering and entering the cells. In this study, a Vp4 gene cloned from a rotavirus strain TB-Chen was highly expressed in E.coli BL21 (DE3). The results of the Western blot showed that the protein possesses specific immuno-reactivities and can be specifically recognized by guinea pig antibodies against rotavirus strain SA11 or Wa. Some Vp4 dimers were formed during renaturation. These data obtained from this study provide a strong basis for further study on the structure and function of the Vp4.

Objective:To compare the anti-thrombin activity and the effects on the coagulation pathway between Whitmania pigra Whitman and Hirudinaria manillensis to provide scientific reference for the anticoagulation mechanism revelation for Hirudo. Methods:Anti-thrombin titration and chromogenic substrate assay-extraction-HPLC were applied to study the anti-thrombin activity of Whitmania pigra Whitman and Hirudinaria manillensis. APTT, PT and TT were determined by a clotting assay to compare the effects on the path-way of blood clotting. Results:The anticoagulation activity order measured by anti-thrombin titration was living Hirudinaria manillensis> dried Hirudinaria manillensis > > dried Whitmania pigra Whitman. The results of chromogenic substrate assay-extraction-HPLC in-dicated that the low dose of aqueous extract promoted the thrombin activity, while the high dose inhibited the thrombin activity. Hirudi-naria manillensis significantly inhibited the activity of thrombin, while Whitmania pigra Whitman showed weak anti-thrombin activity only at the higher dose. All leeches could prolong APTT, PT and TT. However, living Hirudinaria manillensis mainly affected TT, and dried Hirudinaria manillensis mainly affected APTT. Dried Whitmania pigra Whitman dramatically influenced APTT and TT. All the results indicated that the anticoagulant activity of Whitmania pigra Whitmanis was significantly higher than that of Hirudinaria manillen-sis. Conclusion:There are notable differences in the anti-thrombin activity and the effect on the pathway of blood clotting between Whitmania pigra Whitman and Hirudinaria manillensis.
