Cardiovascular disease, with high morbidity and mortality, has been threatening the health of human beings. Therefore, expecting to find a more effective therapeutic method, a plenty of researchers devote themselves to the study of the cardiovascular disease all the time. Since discovered on the heart, M3 receptor of muscarinic acetylcholine receptor (mAchR, M receptor) became a new starting point of the research of the cardiovascular disease. With more and more investigation, many people found that M3 receptor could protect the heart from kinds of cardiovascular disease, which may make it a new hopeful therapeutic point. So, expecting to give support to the reference and encouragement for the study of disease related to M3 receptor in future, this review expounds M3 receptor on the heart from the main following aspects: the effect on the heart, the influence on the cardiovascular disease and the mechanism of M3 receptor involved.

Objective To observe the effect of epidural injection with different dose of butorphanol on the rats' neurological function.Methods A PE-530 catheter was inserted into the epidural space of all the SpragueDawley rats (male, weighting 180 ～210 g) at L1-2 level.After three days, a total of 32 rats without any motor dysfunction were randomly divided into 4 groups as follows saline(NS) group (group C, n= 8 )and butorphanol injection (B) group( B1∶ n=8;B2∶ n=8;B3∶ n=8).Rats in group C were epidurally injected NS 30 μl each ,and rats in group B1, B2 and B3 were respectively epidurally injected Butorphanol 60 μg/30μl, 120 μg/30 μl,240 μg/30 μl (all diluted with NS) ,and 1 time per day for5 days.The neurological function of rats was recorded before injection (T0) and 6h after injection on day 1 ～4(T1 ～T 4) and 6h,24h and 72h after injection on day 5 (T5 ～T7) by BBB (BASSO,BEATTIE and BRESNAHAN ) Score and the inclined plane test .Results Compared with group C ,the BBB score and the inclined plane test of group B1 showed no significant difference throughout the experimental period(P＞ 0.05 ).There was also no significant difference at T0 ～ T3 of group B2 and group B3 compared with group C (P ＞ 0.05 ), while at T4, the BBB score ( ( 18.50 ± 2.00 ) points, ( 16.38 ± 2.33 ) points) and the inclined plane test( (58.75 ± 5.17 )°, (59.38 ± 3.20) ° ) of the two groups were both obviously decreased when compared with group C( (21.00 ±0.00) points, (65.00 ±3.78)°, P＜0.05) ,and the same significant differences appeared at T5,T6 and T7 (P ＜ 0.05 ).Conclusion Repeated epidural injection of butorphanol 60 μg have no effect on neurological function of rats,while repeated epidural injection of butorphanol 120 μg and 240 μg could impaire the neurological function.

Objective To explore the characteristics of common parameters for acupuncture treatment of cancer pain by sorting out the domestic and foreign literature.Method This article collected and sorted out literature on acupuncture treatment of cancer pain in Chinese databases: Chongqing VIP, CNKI and Wanfang Data and English database PubMed. Main Chinese search keywords were针刺,电针,耳穴,针灸,癌痛,癌症and疼痛. English search keywords were acupuncture, electroacupuncture, auricular, cancer pain, neoplasms and pain. The search range was limited to literature collected in large databases since2010. The article type was limited to clinical case studies. Result s: Forty-four pieces of literature were retrieved after repeated literature was excluded. Conclusion s: Combined acupuncture and medicine and composite therapy are mainly selected for acupuncture treatment. Regularities in point selection for acupuncture are often acupuncture at pain points and acupoint selection according to primary diseases. Needle retention time is often between 20 and 30 min. Electroacupuncture stimulation waveforms aremainly sparse-dense waves, the stimulation intensity is as high as the patient can adapt and the treatment frequency is often once daily.

Objective: To investigate the mechanism of combined growth hormone and fibrin glue on early healing of intestinal anastomosis in intra-abdominal sepsis rats.Methods: Male Wistar rats of abdominal sepsis were randomized into 3 groups.Control rats were given intestinal anastomosis after intestinal fistula operation.Glue group was given intestinal anastomosis and fibrin glue after intestinal fistula.GH group was given intestinal anastomosis and fibrin glue and growth hormone after intestinal fistula.FN,?-SMA,VEGF,and apoptosis in anastomoses were measured.Results: Expression of intestinal FN,?-SMA,and VEGF in GH group were higher than those in other groups and apoptosis were lower than others.Conclusion: It is indicated that combined growth hormone and fibrin glue ameliorates healing of intestinal anastomosis in intra-abdominal sepsis rats.

Objective To study the effects of He-Ne laser irradiation dosage on the expression of heat shock protein ( HSP70) and CyclinD_1 in rats with chronic atrophic gastritis ( CAG). Method Fifty-two adult male Wistar rats were randomly divided into five groups: a normal control group, model group and three groups receiving different doses of He-Ne laser irradiation. CAC was induced using an enema of 2% sodium salicylate and 30% alcohol combined with irregular fasting and forced exercise as pathogenic factors. Laser irradiation was applied for 20 days (large dose 6.24 J/cm~2 , medium dose 4. 80 J/cm~2, small dose 3. 36 J/cm~2). The changes in HSP70 and CyclinD_1 expression were observed. Results The expression of HSP70 and CylinD_1 were highest in the normal control group and the small dose laser group. Compared with the model group, the average expression of HSP70 and CyclinD_1 increased significantly in the small dose group. Conclusions Irradiation with a He-Ne laser at 3. 36 J/cm~2 provides good adjuvant therapeutic effect for CAG in rats. After irradiation, the expression of HSP 70 and CyclinD_1 increased. HSP is important in improving mucosal defenses and promoting cell proliferation in CAG, and it can be promoted through small doses of He-Ne laser irradiation.

Objective: To investigate the mechanism of intestinal anastomosis in a rat model of intra-abdominal sepsis.Methods:Male Wistar rats were randomized into 2 groups.Control rats underwent intestinal anastomosis.Sepsis group underwent intestinal anastomosis after intestinal fistula operation.fibronectin(FN),?-smooth muscle actin(?-SMA),vascular endorthelial growth factor(VEGF) and apoqtosis in anastomoses were measured.Results:FN,?-SMA,VEGF in control group were higher than sepsis group and apoptosis were lower than the other.Conclusion:It is indicated that the repair of tissue was out of balance after infection,and the organization repair was retarded.The collagenoblast and the epithelial cell migration were slowed down,and the blood capillary regeneration was slowly.Not only the granulation organization was reduced,but also apoptosis was prematurely appeared.

To investigate the effect of Tanreqing injection on immune activity of peripheral blood lymphocytes of patients with lung cancer. The peripheral blood lymphocytes of patients with lung cancer and healthy persons were separated by the density gradient centrifugation method for subsequent experiments, with those from healthy persons as the positive control. The effect of Tanreqing injection on stimulating the proliferation of lymphocytes with phytohemagglutinin (PHA) was determined by MTT method. The effect of Tanreqing injection on the lymphocyte secretions of IFN-γ and TNF-α and the subset ratio of lymphocytes cultured separately or with Tanreqing injection of different concentrations were examined by ELISA and flow cytometry (FCM) respectively. In addition, the LDH release assay was used to detect the cytotoxicity of cytotoxic T cells (CTL) and natural killer cells (NK). According to the findings, all of immunological indexes of lymphocytes from patients with lung cancer were weaker than that of healthy persons, but with the obvious increases in proliferation activity and IFN-γ and TNF-α secretions of lymphocytes co-cultured with Tanreqing Injection (P < 0.05). Among lymphocyte subsets co-cultured with Tanreqing Injection, CD3+, CD3+ CD4+ and CD3- CD16 + 56+ cell ratios notably increased, whereas CD4+ CD25+ Treg cell ratio obviously decreased (P < 0.05). In the meantime, Tanreqing injection can markedly promote the cytotoxicities of CTL and NK (P < 0.05). In conclusion, Tanreqing injection shows a significant effect in promoting the immune activity of lymphocytes from patients with lung cancer and their anti-tumor immunity.
