Objective To compare different methods for developing rat model of the syndrome of cold fluid retention in lung ( CFRL) , so as to find an easier and more reliable modeling method for CFRL. Methods Twenty rats were divided into 4 groups, namely normal group, lipopolysaccharide (LPS) group, tobacco group, and cold bath group, 5 rats in each group. Lipopolysaccharide group was given intratracheal drip of LPS, tobacco smoking and cold bath, tobacco group was given tobacco smoking and cold bath, and cold bath group was given cold bath and intragastric gavage of cold water. The modeling time in the three groups lasted for 15 days. After the experiment, we compared the general health state, body weight, sputum volume and pathological changes in rats of the four groups. Results (1) Compared with the normal group, activities of rats in the three modeling groups were lowered, body temperature decreased, and the signs of panting, cyanotic nose and lips with excretion, and sneezing (cough) were obvious. (2) Compared with the normal group, the decrease of body weight was obvious (P<0.01), expelling sputum volume was increased (P<0.05) in the model groups. However, the differences among the three model groups had no statistical differences ( P>0.05). ( 3) The results of lung tissue slice examination showed that the injury of lung tissue was severe in LPS group, mild in tobacco group and slight in cold bath group. Conclusion Rat model of CFRL has been established successfully in all of the three modeling groups, and in consideration with all respects, the method for tobacco group is the best.

The aimed of this study was to prepare stabilized thiomers to overcome the poor stability character of traditional thiomers. Poly(acrylic acid)-cysteine (PAA-Cys) was synthesized by conjugating cysteine with poly(acrylic acid) and poly(acrylic acid)-cysteine-6-mercaptonicotinic acid (PAA-Cys-6MNA, stabilized thiomers) was synthesized by grafting a protecting group 6-mercaptonicotinic acid (6MNA) with PAA-Cys. The free thiol of PAA-Cys was determined by Ellmann's reagent method and the ratio of 6MNA coupled was determined by glutathione reduction method. The study of permeation enhancement and stabilized function was conducted by using Franz diffusion cell method, with fluorescein isothiocyanate dextran (FD4) used as model drug. The influence of polymers on tight junctions of Caco-2 cell monolayer was detected with laser scanning confocal fluorescence microscope. The results indicated that both PAA-Cys and PAA-Cys-6MNA could promote the permeation of FD4 across excised rat intestine, and the permeation function of PAA-Cys-6MNA was not influence by the pH of the storage environment and the oxidation of air after the protecting group 6MNA was grafted. The distribution of tight junction protein of Caco-2 cell monolayer F-actin was influenced after incubation with PAA-Cys and PAA-Cys-6MNA. In conclusion, stabilized thiomers (PAA-Cys-6MNA) maintained the permeation function compared with the traditional thiomers (PAA-Cys) and its stability was improved. The mechanism of the permeation enhancement function of the polymers might be related to their influence on tight junction relating proteins of cells.

AIM: Valproic acid (VPA) is a histone deacetylase inhibitor and is believed to have anti-tumor activity. The present study aims to investigate the effect of VPA on the, apoptosis and cytokine synthesis of human peripheral lymphocytes. METHODS: The activation and cytokine synthesis in lymphocytes in whole blood stimulated with phorbol dibutyrate (PDB) and ionomycin were evaluated with flow cytometry after fluorescent staining. The mitochondrial membrane potential was examined using 3, 3-dihexyloxacarbocyanine iodide [DiOC6(3)]staining. RESULTS: VPA at low doses (1 and 5 mmol/L) promoted CD69 expression in activated lymphocytes, whereas it turned to inhibit the expression of CD69 at a high dose (25 mmol/L). Meanwhile, VPA at low doses increased the mitochondrial membrane potential, while a high dose of VPA decreased it in activated lymphocytes. Furthermore, interleukin-2 (IL-2) synthesis was enhanced by low doses of VPA but inhibited by a high dose. However, interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α) synthesis were dose-dependently enhanced by VPA as compared with those of PDB plus ionomycin-treated cells. CONCLUSION: VPA exerts biphasic effect on the further activation and apoptosis of human peripheral lymphocytes stimulated with mitogens and exhibits differential activity on the synthesis of several important cytokines in human lymphocytes.

OBJECTIVETo observe the difference in the analgesic effect on primary dysmenorrheal between acupuncture and sham acupuncture at Sanyinjiao (SP 6) during menstrual pain and evaluate the impact of psychological effect on acupuncture analgesia.
METHODSSixty subjects were randomized into an acupuncture group and a sham acupuncture group, 30 cases in each one. The conventional acupuncture and sham acupuncture were applied to Sanyinjiao (SP 6) on bilateral sides when menstrual pain began to attack and needles were retained for 30 min each time. Three menstrual cycles were required. The visual analogue scale (VAS) was adopted to determine the scores before and 0. 5 h, 1 h, 3 h, 6 h and 12 h after acupuncture during menstrual pain in each cycle separately.
RESULTSIn the acupuncture group, VAS score at each time point after acupuncture was reduced as compared with that at the previous one during menstrual pain in each menstrual cycle, indicating the significant difference (all P<0. 05). In the sham acupuncture group, the scores in 6 h and 12 h of acupuncture were reduced as compared with the previous one, indicating the significant difference (all P<0. 05). After acupuncture, VAS score at each time point in the acupuncture group was lower than that in the sham acupuncture group (all P<0. 05).
CONCLUSIONThe conventional acupuncture at Sanyinjiao (SP 6) achieves the significant analgesic effect on primary dysmenorrheal. The psychological placebo effect of sham acupuncture has no obvious impact on acupuncture analgesia.
