Purpose To investigate the expression of muscarinic cholinergic receptor 3 (M3R) in small cell lung cancer (SCLC) and the correlation between it and clinical characteristics of SCLC. Methods The M3R expression was examined in 60 SCLC patients ad-mitted using immunohistochemistry. The patients were evaluated by clinical history, physical examination and chest CT. Survival time was got through telephone follow-up. Results The M3R expression in primary SCLC tissues was higher than that in normal lung tis-sues. The M3R expression had no difference between limited-disease and extensive-disease of SCLC. There was no correlation between M3R expression and age, gender, lymph node metastasis. The M3R expression was significantly correlated with smoking history. The survival time of M3R negative patients was longer than that of M3R positive patients in Kaplan-Meier survival curve. Conclusion The M3R expression in primary SCLC tissues was higher than that in normal lung tissues. M3R expression had some correlation with prog-nosis of SCLC patients.

Objective To observe the effect of auricular point sticking plus breast massage with rehabilitation apparatus on lactation in the puerperant. Methods Totally 127 in-hospital primiparae were randomized into a treatment group of 62 cases and a control group of 65 cases. The control group was intervened by conventional nursing care, while the treatment group was by auricular point sticking plus breast massage with rehabilitation apparatus in addition to the conventional nursing care. The lactation yield, initial lactation time, and the change of prolactin (PRL) were observed. Results There were significant differences in comparing the lactation yield grading and initial lactation time between the two groups (P＜0.05). There were significant differences in comparing the serum PRL level on the postpartum day 1, 2, and 5 between the two groups (P＜0.01, P＜0.05). Conclusion Auricular point sticking plus breast massage with rehabilitation apparatus can promote milk secretion, the initial lactation time, PRL production, and the breast feeding rate.

The literature analysis and case analysis were used to analyze the current situation and problems of the patent protection of Chinese medicine.The patent of artemisinin was registered abroad as the failure case, while Tasly developed the construction of the patent net overseas as a successful case. The intellectual property right of traditional Chinese medicine has started late in China, so the Chinese pharmaceutical enterprises lacked awareness of the intellectual property protection of Chinese medicine, and it is difficult for us to have comprehensive intellectual propertyright protection in traditional Chinese medicine. The intellectual property system of Chinese medicine in China needs improvement.

Objective To evaluate the safety and feasibility of three-dimensional conformal radiation therapy combined with tegafur in treating locally recurrent rectal cancer. Methods A total of 32 patients with locally recurrent rectal cancer were treated with chemoradiotherapy ( CRT) . Radiotherapy was delivered to a total of 45 Gy in 25 fractions followed by a boost of 18 Gy in 10 fractions using three dimensional radiotherapy planning. Tegafur was given orally[80 mg·(m2)-1·d-1] on days 1-5, 8-12, 15-19, 22-26, 29-33, 36-40, and 43-47 during radiotherapy. Results Most of the adverse effects were mild. Grade 3-4 toxic effects occurred in 12. 5% of patients. Thirty-one patients completed full course of CRT, while one patient discontinued chemotherapy due to Grade 4 thrombocytopenia. There were 3 cases (9. 4%) with complete response, 21 cases (65. 6%) with partial response, and the overall response rate was 75. 0%. Overall pain response (complete and partial pain relief) was achieved in 96. 9% of patients. The 1- and 2-year overall survival rate was 71. 0% and 56. 5%, respectively. Conclusion 3D-CRT combined with tegafur for locally recurrent rectal cancer is feasible with high patient compliance and tolerable toxicities.

Objective To investigate the effect of super-selective intracoronary administration on acute myocardial in farction patients.Methods A total of 240 patients with ST-segment elevation myocardial infarction who received emergency percutaneous coronary intervention in our department from March 2012 to January 2014 were selected and divided into the intravenous drug administration group (n=77),the conventional intracoronary drug administration group (n=81) and the super-selective intracoronary drug administration group (n=82).Parameters,including the Thrombolysis in Myocardial Infarction (TIMI) classification,ST segment resolution after operation,peak values of creatine kinase MB (CK-MB) and troponin-I (cTn-I),left ventricular ejection fraction,left ventricular end-diastolic diameter (LVEDD),major adverse cardiovascular events and bleeding events,were compared between the groups.Results There were no significant differences in TIMI flow grade between the three groups (x2 =0.14,P=0.529).The percentage of patients with complete ST segment resolution after operation was higher in the super-selective intracoronary drug administration group than in the intravenous drug administration and conventional intracoronary drug administration groups (74.4％ vs.62.3％,61.7％,x2 =8.24,P＜0.05).Peak values of CK-MB and cTn-I were lower in the super-selective intracoronary drug administration group than in the other groups (P＜0.05).There were no significant differences in left ventricular ejection fraction and LVEDD between the three groups after operation,but left ventricular ejection fraction and the incidence of angina pectoris significantly improved in the super-selective intracoronary drug administration group than in the other groups after a three month follow-up (P＜0.05).There were no significant differences in target lesion revascularization,nonfatal myocardial infarction and druginduced thrombocytopenia between the three groups (P ＞ 0.05).Conclusions Super-selective intracoronary drug administration can significantly enhance cardiac function and alleviate angina pectoris in patients with acute myocardial infarction,and should be a recommended method.
