Objective To investigate the effect of penehyclidine (PHCD) pretreatment on Toll-like receptor 4 (TLR4) mRNA expression in the lung following acute lung injury (ALI) induced by hemorrhagic shock in rats. Methods Forty healthy SD rats of both sexes weighing 200-250 g were randomly divided into 5 groups( n = 8 each): group Ⅰ sham operation (group S); group Ⅱ ALI (group ALI); group Ⅲ, Ⅴ, PHCD 0.3,1.0, 3.0 mg/kg were given iv respectively at 30 min before hemorrhagic shock (P1-3). Hemorrhagic shock was induced by exsanguinations. MAP was maintained at 35-45 mm Hg for 60 min. The animals were killed at 4 h after resuscitation. Their lungs were removed for microscopic examination, W/D lung weight ratio and determination of TLR4 mRNA expression in the lung tissue (by RT-PCR). NF-κB p65 protein expression in the lung tissue was determined (by immuno-histochemical staining). Results Hemorrhagic shock significantly increased TLR4 mRNA and NF-κB p65 protein expression in the lung tissue and W/D lung weight ratio. Pretreatment with PHCD 1.0 or 3.0 mg/kg significantly inhibited hemorrhagic shock-induced increase in TLR4 mRNA and NF-κB p65 protein expression in the lung and W/D lung weight ratio. The lung injury was significantly ameliorated in group P2,3 as compared to group ALI. Conclusion PHCD pretreatment can attenuate ALI induced by hemorrhagic shock through down-regulation of TLR4 mRNA expression and decreasing NF-κB activity in the lung.

Objective To examine the relationship between plasma soluble interleukin 2 receptor(sIL2R), bone metabolism markers, and bone mineral densities in female patients with Graves′ disease(GD), and to explore the role of sIL2R in bone metabolism of GD.Methods This study included 201 female GD patients.FT3, FT4, TSH, PTH, osteocalcin(OCN), C-terminal telopeptides of type Ⅰ collagen (CTX), procollagen type I N-terminal propeptide(PINP), and 25-(OH)-vitamin D(25OHD) were measured using electrochemical luminescence technique.sIL2R was measured using chemiluminescence method.All pations underwent examinations of bone mineral densities at lumbar spine, total hip, and femoral neck(LS-BMD, TH-BMD, and FN-BMD).The associations of sIL2R with bone metabolism markers and bone mineral densities were analyzed.Results OCN,CTX,PINP gradually decreased across the tertile groups of LS-BMD, TH-BMD, FN-BMD(all P<0.05).FT3, sIL2R gradually increased across the tertile groups of OCN, CTX, PINP(all P<0.05).Multiple linear regression analysis showed that sIL2R was independently associated with OCN and CTX(both P<0.05).Conclusion The increase of bone turnover leads to bone loss in female GD patients.The plasma level of sIL2R was positively correlated to bone turnover, which indicated that sIL2R may play an important role in bone metabolism of GD.

OBJECTIVETo verify the clinical efficacy on chronic fatigue syndrome of qi deficiency syndrome treated with acupuncture at selective time and explore the effect mechanism.

METHODSEighty patients were randomized into a selective-time-acupuncture group and an acupuncture group, 40 cases in each one. Qihai (CV 6), Guanyuan (CV 4), Hegu (LI 4), Taichong (LR 3), Sanyinjiao (SP 6) and Zusanli (ST 36) were selected in the two groups. In the selective-time-acupuncture group, acupuncture was used at 9:00am to 11:00am. In the acupuncture group, acupuncture was used at any time except in the range from 9:00am to 11:00am. No any manipulation was applied after the arrival of needling sensation. The treatment was given once every day, 10 day treatment made one session and two sessions of treatment were required. The fatigue scale was adopted to evaluate the efficacy before and after treatment in the patients of the two groups. The ratios among CD3+, CD4+ and CD8+ T cells in the peripheral blood were detected before ad b a after treatment.

RESULTSIn the acupuncture group, the total score of fatigue and the score of physical fatigue were reduced after treatment as compared with those before treatment (all P<0.05). In the selective-time -acupuncture group, the total score of fatigue, the s core of physical fatigue and the score of mental fatigue after treatment were reduced obviously as compared with those hefore treatment (all P<0. 01). The improvements in the scores of the selective-time-acupuncture group were superior to the acupuncture group (all P<0. 05). The ratio of CD3+ and CD8+ T cells was increased obviously after treatment in the two groups (all P<0. 05) and the ratio of CD4+ and CD8+ T cells was reduced obviously in the selective-time-acupuncture group (P<0. 05), which was better than that in the acupuncture group (all P<0.05). The total effective rate was 95.0% (38/40) in the selective-time-acupuncture group, which was better than 80.0% (32/40) in the acupuncture group (P<0.05).

CONCLUSIONThe acupuncture therapy at selective time is effective in the treatment of chronic fatigue syndrome of qi deficiency syndrome, which is especially better at relieving mental fatigue. The effect of this therapy is achieved probably by improving the immune function via the regulation of the ratios among CD3+, CD4+ and CD8+ T cells.

OBJECTIVEMedicinal properties are the basic attribute of traditional Chinese medicines (TCM), while the medicinal property theory is the core theoretical foundation of TCM formula combination. In this particle, authors studied the characteristics of pharmacological effects of property combination of traditional Chinese medicines distributing along meridians, with the aim to introduce the medicinal property combination regularity into the design and optimization process of compound TCMs, and bring the medicinal property theory into full play in guiding the formula combination.

METHODIn this paper, TCMs distributing along "the lung meridian" was taken for example. The medicinal property combinations of TCMs distributing along "the lung meridian" recorded in Pharmacopeia (2010) was collected and processed. Besides, Chinese journal full-text database (CNKI) was used to collect all of pharmacological study literatures concerning the above TCMs that have been published since 1980. The pharmacological information was also supplemented by reference to Science of Chinese Materia Medica and Clinical Science of Chinese Materia Medica.

RESULTTCMs distributing along the lung meridian with different properties and tastes showed significant differences in pharmacological effects. For example, mild-sweet-lung medicines could lower blood sugar levels, decrease anoxia and enhance immunity; Mild-bitter-lung medicines showed anti-bacterial, anti-hypertension, anti-oxidation effects; Hot-sweet-lung medicines showed antibechic and anti-bacterial effects. And Hot-bitter-lung medicines showed phlegm eliminating and anti-inflammatory effects. Meanwhile, TCMs distributing along the lung meridian had similar pharmacological characteristics, such as anti-bacterial and anti-inflammatory effects, which is consistent with lung's feature in susceptibility to exogenous pathogenic factors.

CONCLUSIONIn this study, authors discovered pharmacological characteristics of different TCMs distributing along the lung meridian, which links TCM theory with modern study achievements and lays a foundation for establishing a TCM property formula combination system.

Studies on the prescription combination regularity based on medicinal tastes focus on the internal relations between the structure and hierarchy of the prescription combination system. In this paper, with the systematic and scientific self-similarity theory as the core ideology, authors systematically interpreted the self-similarity theory of medicinal properties, defined the self-similarity of prescriptions with identical or similar medicinal properties, and built the systematic view of medicinal property theory based on the prescription combination based on the entity grammar system. As a result, the system was conducive to integrating traditional Chinese medicinal knowledge of syndromes, therapeutic principles, efficacies, medicinal properties and tastes and achieving the automatic design and optimization process from symptoms to prescriptions, and providing scientific and feasible methods and technical systems for the application of the medicinal property theory, with a guiding significance to the technology, methodology and theory of decoction pieces compatibility, component compatibility and compound medicine design.
