Objective:To understand the drug purchase behaviors and prescription flows of outpatients and their influencing factors. Methods: After selecting and investigating tertiary hospitals, secondary hospitals, community health service centers ( one per each level) in Beijing, Zhengzhou, Guangzhou, this paper uses structured question-naire method to analyze 3,155 valid questionnaires. A logistic regression analysis is performed to understand the fac-tors influencing the drug purchase behaviors. Results:The factors influencing the drug purchase behaviors of outpa-tients mainly include the region where the patient is, level of the hospital, type of health insurance that the patient has, frequency of drug purchase, etc. Conclusions: This paper suggests hospital administrators to take measures to improve prescription flows, such as reforming the health care insurance to make payment system more suitable for pharmacies standardizing supply channels in order to make varieties consistent between hospitals and pharmacies, strengthening education and publicity to raise the outpatients’ awareness for drug purchase outside of hospitals, etc.

This article was aimed to study the distribution and effects of apolipoprotein E (ApoE) gene polymorphism of different constitutional types among coronary heart disease (CHD) patients with blood stasis syndrome on vascular endothelial cell (VEC) function. The whole gene sequencing method was used to identify genotypes of ApoE gene among 556 CHD patients with blood stasis syndrome, in order to analyze the relationship between polymorphism of ApoE gene and the level of VEC function. The results showed that the frequency of E3/3 genotype of each physical group was significantly lower than that of the healthy group; and the frequency of E3/4 genotype was significantly higher than that of the healthy group. In addition, the frequency of E3/3 genotype in qi deficiency constitution group was higher than that of blood stasis constitution group and yang deficiency constitution group; but the frequency of E3/4 genotype in blood stasis constitution group and yang deficiency constitution group was higher than that of the qi deficiency constitution group. The levels of ET and ET/NO in each of genotype groups of blood stasis constitution, yang deficiency constitution, qi deficiency constitution of CHD patients with blood stasis syndrome were higher than that of the healthy group (P < 0.05). In the genotype group of blood stasis constitution of CHD patients with blood stasis syndrome, the frequency of E3/4+E4/4 genotype ET was higher than that of other genotypes (P < 0.01). The levels of ET, NO, ET/NO in genotype groups of yang deficiency constitution and qi deficiency constitution of CHD patients with blood stasis syndrome were not significantly different. It was concluded that ApoE genotype E3/4, E3/3 may be the susceptible genotypes of blood stasis syndrome in CHD. There is a certain difference among different constitutional types. CHD with blood stasis syndrome patients, who are the constitution of blood stasis, carrying the ApoE gene polymorphism of E4 allele may have the function of increasing the ET level.

Objective To study the distribution of body constitutions of CHD patients with blood stasis syndrome;To explore the relationship between different body constitutions and their blood lipid levels.Methods WANG’s Constitutional Classification was used to diagnose body constitutions of 600 CHD patients with blood stasis syndrome, and analyze the relationship between the different body constitutions and triglyceride (TG) level, low density cholesterol (LDL-C) level, high density cholesterol (HDL-C) level.Results The four most common body constitutions of CHD patients with blood stasis syndrome in Taiyuan area were the constitutions of blood stasis, yang deficiency, qi deficiency and yin deficiency. The TG levels of the four body constitutions were higher than those of healthy people (P<0.01), but there was no obvious difference among TG levels of different body constitutions. The LDL-C level of the patients with the body constitution of blood stasis was higher than that of patients with other body constitutions and healthy people (P<0.01). Compared with healthy people, there was no obvious difference among HDL-C levels of different body constitutions (P>0.05).Conclusion There is a certain difference among the blood lipid levels in different body constitutions of CHD patients with blood stasis syndrome, and the patients of blood stasis syndrome with high LDL-C level are more dangerous than patients with other body costitutions.

Anti-glutamic acid decarboxylase antibody-associated encephalitis is a kind of autoimmune encephalitis mediated by anti-glutamic acid decarboxylase antibody, which belongs to anti-neuronal intracellular synaptic protein antibody-associated encephalitis. Clinical manifestations include stiff-person syndrome, cerebellar ataxia, limbic encephalitis, seizures, etc., often associated with a variety of autoimmune diseases, rarely associated with tumors. Detection of anti-glutamic acid decarboxylase antibody is crucial for clinical diagnosis. Immunotherapy helps to relieve symptoms and improve prognosis. The incidence of this disease is low, and there are few reports at home and abroad. This paper intends to review the research on this encephalitis, hoping to improve the clinicians′ understanding and the level of diagnosis and treatment of the disease.

To investigate physicians' knowledge about chronic obstructive pulmonary disease (COPD) in tertiary hospitals in northeast China.Physicians from 77 tertiary hospitals in northeast China were surveyed with a questionnaire,which included questions such as risk factors,symptoms,exacerbations,comorbidities and diagnostic criteria of COPD.Besides cigarette smoking,air pollution and pulmonary infections,only 22.5％ (40/178) physicians recognized that the biomass fuels may induce COPD.Totally 59.0％ (105/178) physicians recognized the importance of spirometry to the diagnosis of COPD.Besides dyspnea,cough,sputum production,wheezing and chest tightness,only 23.7％ (42/177)of physicians considered that limitation of activity was an important symptom of COPD.65.5％ (116/177)physicians believed that recurrent lung infections was one of the most important comorbidities of COPD.However,less than 30％ [20.9％ (37/177)-28.8％ (51/177)] physicians were aware of the other important comorbidities.The physicians of tertiary hospitals in northeast China need to be systematically educated on COPD to meet the new guideline.

Objective To explore the expression of Metastasis-associated in colon cancer-1 (MACC1) in patients with nasopharyngeal carcinoma (NPC), and its relationship with clinical pathologic characteristics and prognosis Methods The expression of MACC1 was detected in 130 cases of NPC and the relationship among the MACC1 expressions, clinical pathologic characteristics and prognosis of NPC was analyzed. Results Positive expression rate of MACC1was 68.5% in the NPC and MACC1 expression was associated with advanced T stages, lymph node metastasis and advanced clinical stages of NPC (P < 0.05). The results of Kaplan-Meier survival analysis showed that the five year overall survival rate in patients with positive expressions of MACC1 (45.9%) was significantly lower than that of those with negative expressions (73.7%) and the difference was statistically significant (P < 0.05), Cox multi-factor analysis results showed that MACC1 expression was an independent prognostic factor for NPC (P = 0.004). Conclusion MACC1 abnormal expression is closely related to the invasion and metastasis of NPC and it is expected to become a new target for gene therapy of NPC.
