OBJECTIVETo observe the effect of external application of Zhuangshenling Recipe (ZR) combined with Western medicine (WM) on the heart function of chronic heart failure (CHF) patients of Xin-Shen yang deficiency, interior retention of water-fluid syndrome (XSYDIRWFS).

METHODSTotally 140 CHF patients of XSYDIRWFS were randomly assigned to two groups, the treatment group and the control group, 70 in each group. All patients received WM therapy. Those in the treatment group were applied with ZR at Xinshu (BL15) and Shenshu (BL23), while those in the control group were applied with placebos at Xinshu (BL15) and Shenshu (BL23). The therapeutic course for all was 12 weeks. The integrals of TCM syndrome, grading of cardiac function, brain natriuretic polypeptide (BNP), and 6 min walking distance were observed before and after treatment.

RESULTSAfter twelve weeks of treatment, the effective rate of improved grading of cardiac function, the total effective rate of TCM syndrome efficacy, and the BNP level were obviously better in the treatment group (P < 0.05). There was no statistical difference in 6 min walking distance between the two groups (P > 0.05).

CONCLUSIONExternal application of ZR combined with WM could improve the heart function of CHF patients of XSYDIRWFS.

Identification and validation of a new target is one of the most important steps for new antituberculosis (TB) drug discovery. Researches have shown that Mycobacterium tuberculosis (Mtb) encodes 20 CYP450 enzymes which play important roles in the synthesis and metabolism of lipid, cholesterol utilization, and the electron transport of respiratory chain in Mtb. With the critical roles within the organism as well as the protein structures of six Mtb CYP450 enzymes being clarified, some of them have been highlighted as potential anti-tuberculosis targets. In this paper, the phylogenetic analysis, the structural features, and the enzymatic functions of Mtb CYPs, as well as the mechanism of interactions with selective inhibitors such as azole antifungal agents for the CYPs have been reviewed and summarized. The druggability of the CYPs has also been analyzed for their further utility as targets in high throughput screening and rational design of more selective inhibitors.

Objective To evaluate the changes of cerebrospinal fluid dynamics of Chiari malformation type I associated syringomyelia patients with phase-contrast MRI (PC-MRI).Methods Thirty cases diagnosed with Chiari malformation type Ⅰ associated with syringomyelia clinically underwent cisterna plasty treatment.Cerebrospinal fluid dynamics changes were measured before 24 h and 6 months after operation with PC-MRI.The stroke volume (SV),mean flow (MF),regurgitation fractions (RF) and the maximum peak flow velocity (Vmax) were analyzed.Results After operation,PC-MRI showed SV and MF increased,the bidirectional Vmax decreased,which had statistical difference compared with those of preoperation (all P＜0.05),and the C2-3 level was the most obvious.Conclusion PC-MRI can quantitative analysis of preoperative and postoperative changes of cerebrospinal fluid flow and peak velocity.

AIM: To investigate the role of nitric oxide synthase (NOS), soluble guanylyl cyclase (sGC) and protein kinase C (PKC) signaling in tumor necrosis factor-? (TNF-?)-induced cardioprotection against hypoxia/reoxygenation (H/R) injury. METHODS: Neonatal rat ventricular myocytes were pretreated with TNF-? or sodium nitroprusside (SNP) or L-arginine (L-Arg), respectively, for 12 h and then subjected to continuous hypoxia for 12 h, followed by reoxygenation for 6 h. The manganese superoxide dismutase (Mn-SOD) activity of the cells was measured after H/R. Myocyte injury was determined by the release of lactic dehydrogenase (LDH). RESULTS: TNF-? (10~5 (U/L)) significantly increased the Mn-SOD activity and decreased release of LDH from ventricular myocytes. The cardioprotection against H/R injury was induced by the pretreatment with SNP (5 ?mol/L) or L-Arg (5 mmol/L), which was blocked by ODQ (10 ?mol/L), the specific sGC inhibitor, and Chel (5 ?mol/L), the specific PKC inhibitor. Pretreatment with L-NAME (100 ?mol/L), ODQ, Chel, antoxidant 2-MPG (400 ?mol/L) or tyrosine kinase inhibitor genistein (50 ?mol/L) attenuated the increased Mn-SOD activity and reduced LDH level induced by TNF-?. CONCLUSION: The results suggest that NO may play a role in TNF-?-induced cardioprotection, which is mediated by sGC and PKC. [

This study was based on live yeast cell derivative (LYCD), which was produced by live yeast cell stressed with high temperature and H 2O 2. The results showed that pretreating of low dose(37℃and 0.2mmol/L H 2O 2) could increase the content of GSH and the activity of SOD and CAT. These pretreatment could induce the resistance to lethal concentration of H 2O 2. LYCD was produced by yeast treated with 37℃ and 0.2mmol/L H 2O 2. And it was found that the survival of yeast treated with lethal concentration of H 2O 2 obviously increased, while LYCD was added in yeast culture. It indicated that LYCD could have resistance to oxidative condition.

Objective: To establish C57BL/6 transgenic mice lineages containing pMTR1 plasmids as an efficient animal model for studying gene mutation in vivo . Methods: The linearized pMTR1 DNAs, constructed by molecular cloning, were injected into 572 fertilized eggs of C57BL/6 mice by microinjection. The manipulated embryos were transferred into the oviducts of 45 pseudopregnant mice respectively, from which 35 offsprings were obtained. The genomic DNAs of these offsprings were analyzed with PCR and genomic Southern blotting. Four mice whose genomes integrated with copies of intact pMTR1 vectors were chosen as founders to establish transgenic mice lineages. The recovery of pMTR1 plasmid were conducted on the genomic DNAs of F1 or F2 transgenic offsprings. Results: It was showed that intact and functional pMTR1 plasmid could be efficiently recovered from the genomic DNAs of these mice. Conclusion: (1) The transgenic mouse lineages containing copies of a stably integrated pMTR1 plasmid is established. (2) The transgenic mice are suitable models for studying gene mutation in vivo .

Objective: To observe the inhibitory effect of scopolamine(Spm) and chlopromazine (Clo) on withdrawal syndromes in morphine dependent rats. Methods: The intensity of withdrawal syndromes on the model of morphine dependent rats was recorded after single or muiltiple subcutaneous administration(sc) of Spm and Clo at different doses. Results: Withdrawal syndromes were markedly decreased when single Spm 1 mg/kg and Clo 0.5 mg/kg combined with morphine were injected (P<0.05). Spm+Clo(sc) had much stronger effects on inhibiting withdrawal syndromes after intraperitoneal (ip) naloxone in morphine dependent rats (P<0.01). Conclusion: Spm can act on Ach-receptor and relieve morphine withdrawal syndromes. Clo may have a synergistic action with Spm via α2-receptor in the locus coeruleus of the rat brain stem.

Objective To comparison anterior cervical decompression and plating techniques for CSM between under microscope and traditional method retrospectively, investigate clinical result of surgery under microscope. Methods Sixty-seven patients with CSM underwent surgery of anterior cervical decompression and plating techniques were evaluated retrospectively from January 2008 to June 2010. Thirty-three patients underwent operation under microscope; thirty-four patients underwent traditional operation. The operating time, bleeding volume during operating and poster operating, walking time post-operation and complication were observed. Clinical outcomes were assessed by Japanese Orthopaedic Association (JOA), Image of before and after operation. Results Microsurgery operation time averaged of 100 minutes. Bleeding volume during the operation averaged of 60 ml, and after operation averaged of 40 ml. The JOA scores were improved from 8.43 pre-operatively to 14.70. Six months post operation, the average rage of JOA improvement were 83.2%. Traditional operation time averaged of 115 minutes. Bleeding volume during operation averaged of 100 ml, and after operation averaged of 50 ml. The JOA scores were improved from 7.45 pre-operatively to 11.84. Six months post operation, the average rage of JOA improvement were 82.1%. There were difference between two groups(P ＞ 0.05) in the JOA scores. No statistical difference (P ＜ 0.05) in bleeding volume and operating time. Conclusion The operation under microscope is restored significantly than the traditional method in bleeding volume, the surgical field, safety of operation, time of recovery and so on.
