OBJECTIVETo observe the impacts of the acupoint catgut implantation on postpartum pain of uterine contraction with qi and blood deficiency.

METHODSOne hundred and ten primiparas of natural delivery differentiated as qi and blood deficiency pattern in TCM were selected as the subjects. They were randomized into an acupoint catgut implantation group (55 cases) and a routine nursing group (55 cases). In the acupoint catgut implantation group, the catgut was implanted in Zigong (EX-CA 1), Zusanli (ST 36), Sanyinjiao (SP 6), Pishu (BL 20) and Geshu (BL 17) in 6 h after delivery; additionally, the routine post-delivery nursing was adopted. In the routine nursing group, the routine post-delivery nursing was applied simply. Visual analogue scale (VAS) and the pain relief time of uterine contraction were compared in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation between the two groups.

RESULTSVAS Scores in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation in the acupoint catgut implantation group were lower apparently than those in the routine nursing group (3.31 +/- 0.39 vs 4.31 +/- 0.29, 1.86 +/- 0.29 vs 2.66 +/- 0.25, 0.89 +/- 0.21 vs 1.59 +/- 0.24, 0.35 +/- 0.10 vs 0.69 +/- 0.13, all P < 0.05). The pain relief was achieved in (72.06 +/- 6.83) h in the acupoint catgut implantation group and was (123.42 +/- 11.12) h in the routine nursing group. The pain relief in the acupoint catgut implantation group was achieved more quickly (P < 0.01).

CONCLUSIONThe intervention of acupoint catgut implantation in 6 h after natural delivery in primiparas prevents effectively postpartum pain of uterine contraction.

Fibrolase is a non-hemorrhagic zinc metalloproteinase isolated from southern copperhead snake venom (Agkistrodon contortrix contortrix) and is capable of degrading fibrin clots resulting from purified fibrinogen or from blood plasma. Alfimeprase, a truncated form of fibrolase, as a clinical agent was successfully completed PhaseII clinical trials.The cDNA of alfimeprase was amplified by recursive PCR, digested with BamHI and HindII, and cloned into pET43.1a, pMALp2X and pMALc2X vectors to generate fusions with NusA, MBP and sMBP(with signal peptide), respectively. Nus/alfimeprase was expressed in soluble form by co-expressing with chaperone FkpA and inducing with1mmol/L IPTG. The fusion protein accounted for about 25 % of total protein following cell lysis. Alfimeprase was successfully purifiesd by Ni-NTA affinity chromatography and cleaved by enterokinase. The results demonstrate the fibrinolytic activity of recombinant alfimeprase using fibrin plate assays and fibrinogen hydrolysis.

Objective: To assess the effect and mechanism of compound Xiansu capsule (仙酥胶囊, XSC) combined with chemotherapy in treating gastric carcinoma of mid-late stage. Methods: Sixty-one patients of the test group were treated by XSC combined with chemotherapy and 30 patients of the control group treated with chemotherapy alone. The effect of treatment and cell mediated immunity of patients were observed. Results: The effective rate of the test group and the control group was 32.8% and 13.3% respectively (P<0.05), the toxic reaction occurrence caused by chemotherapy was less in the former than that in the latter group (P<0.01). The CD8 level of patients in the test group decreased, and CD4/CD8 level was raised obviously, which suggested that XSC had immuno-regulating effect on T-cell. Conclusion: XSC could enhance the efficacy and reduce the toxic and side-effect of chemotherapy. To regulate the cell mediated immunity of patients is possibly its mechanism.

OBJECTIVETo develop a virulent heat-evil-induced thrombosis animal model, and provide a rational animal model for pathogeny and pathogenesis research of thrombosis-related diseases, anti-thrombosis activity screening and pre-clinical studies of CAHT formula.

METHODSD rats were pretreated with carrageenin (Ca) intraperitoneal injection, followed by intravenous injection of endotoxin (LPS from E. coli O111:B4) 50 microg x kg(-1) 16 h later. Thrombosis in rat tails were observed during 12-24 h after injection of LPS. The inflammatory mechanism of this model were investigated by analyzing serum level of TNF-alpha, IL-6, TXB2 and 6-keto-PGF 1alpha, CD11b/CD18 expression of white blood cells (WBC) and P-selectin expression of vessel walls.

RESULTIn LPS/Ca model group, thrombosis can be clearly observed in the distal part of rat tails after 12-24 h of LPS/Ca treatment. High level of TNF-alpha and IL-6 can be measured in serum. The expression of CD11b/CD18 in WBC and P-selectin in vessel endothelium significantly increased and the number of WBC in peripheral blood markedly decreased shortly after LPS/Ca treatment. The adherence of white blood cells to vessel endothelium which can be seen by microscope mainly contributed to the decrease of WBC. The results indicated that there was obvious inflammation after treatment with LPS/Ca, suggesting that inflammation was the key mechanism for this model.

CONCLUSIONThis model was developed through treatment of LPS in combination with Ca, of which LPS is considered to be an exotic virulent heat-evil in TCM, while the inflammatory molecules produced in this model, such as TNF-alpha, IL-6, CD11b/CD18 and P-selectin belong to internal virulent heat-evils, so this animal model consists of pathogeny and pathogenesis of virulent heat-evils. virulent heat-evil.

OBJECTIVELong time exhaled oxygen will induced oxygen toxicity. Some studies had found that different pathology may exised in normobaric and hyperbaric pulmonary oxygen toxicity, and nitric oxide synthase (NOS) may play a role. In this study, we discussed the change of NOS in normobaric and hyperbaric pulmonary oxygen toxicity.

METHODSSixty male SD rats were randomly divided into 6 groups (n = 10), exposed to 1 ATA (atmosphere absolute), 1.5 ATA, 2 ATA, 2.5 ATA and 3 ATA, 100% oxygen for 56, 20, 10, 8, 6 hours respectively. Rats were exposed to air as control. After exposure, the protein in bronchoalveolar lavage fluid (BALF), the wet/dry weight of lung and the expression of eNOS, nNOS in lung were defined.

RESULTSAs compared to air group, the protein in BALF, the wet/dry of lung were significantly elevated in 1.0 ATA group, while these changes were not so obviously in the other groups, and these changes in hyperbaric oxygen group (approximately 1.0 ATA) were significantly decreased as compared with nonnrmobaric oxygen group (1.0 ATA). The expression of nNOS were not changed in normobaric and hyperbaric pulmonary oxygen toxicity, while the expression of eNOS was significantly decreased in 2 ATA group, and significantly elevated in 2.5 ATA and 3 ATA group.

CONCLUSIONThe expression of eNOS can change when exposed to different pressures of oxygen.

OBJECTIVETo investigate the changes in contents of cycloxygenase-2 (COX-2) and its downstream effectors in rat's myocardial ischemia/reperfusion (I/R) model and observe the effects of precondition with GBE50 (Ginkgo biloba extract 50) and Salviae miltiorrhizae (SM) on them.

METHODSRat's I/R model was established by 30-min left anterior descending coronary artery occlusion followed with 60-min reperfusion. Animals were divided into the model control group, the sham-operated group and the tested groups (received 1-week precondition with GBE50 and SM respectively via intragastric infusion before modeling). COX-2 mRNA expression in myocardium was detected by real-time PCR; contents of thromboxane B2 (TXB2) and 6-keto-prostaglandin F1alpha (6-keto-PGF1alpha) were measured by radioimmunoassay.

RESULTSThe mRNA expression of COX-2 in the model group was obviously higher than that in the sham-operated group (P < 0.001), while that in the tested groups was down-regulated significantly (P < 0.01), and the content of TXB2 as well as the ratio of TXB2/PGF1alpha was reduced significantly (P < 0.05). Besides, SM also showed the up-regulation effect on 6-keto-PGF1alpha content in myocardium (P < 0.05).

CONCLUSIONCOX-2 affects the myocardium through thromboxane A2 and prostacyclin after I/R; both GBE50 and SM can inhibit the production of COX-2, but they may act in different paths.
