Objective To investigate the awareness rate of TCM knowledge, the application, and demand situation of Chinese appropriate techniques in health clinics in towns and townships of Hunan Province;To put forward the countermeasures of TCM continuing education. Methods 50%of the training doctors were adopted randomly from 4 training courses in health clinics in towns and townships in Hunan Province. The student number of each course was 49, 51, 53, 53, respectively. Self-designed questionaires were used to investigate 206 training doctors. Results 168 (81.55%) doctors’ degrees were technical secondary school degree and college degree;186 (90.29%) doctors’ professional titles were physician assistant and physician;The awareness rate of TCM knowledge was 63.83%;Different study backgrounds of doctors had different effects on the rate of TCM knowledge (χ2=42.42, P=0.01). The using rates of TCM appropriate techniques were all lower than 30%. 96.60%of doctors in health clinics in towns and townships hope to learn one or more TCM appropriate techniques to help diagnose and treat disease. Conclusion The degree, professional title, mastery of TCM knowledge, and TCM appropriate techniques were not optimistic. The doctors in health clinics in towns and townships showed strong desire for TCM appropriate techniques. The health department should combine the actual situation of doctors in health clinics in towns and townships and develop targeted TCM continuing education.

Objective To learn therapeutic effect of the combined treatment of mecobalamin and salvia milti-orrhiza ligustrazine on diabetic peripheral neuropathy.To provide effective and reliable operation method for the treat-ment of disease.Methods 163 cases with diabetic peripheral neuropathy were randomly divided into observation group(86 cases)and control group(77 cases).The observation group was treated with mecobalamin combined salvia miltiorrhiza ligustrazine,the control group was treated with mecobalamin.The sensory conduction velocity (SNCV) and motor conduction velocity (MNCV)were measured in the two groups before and after treatment.The therapeutic effects were evaluated after one course.Results The MNCV and SNCV of the two groups were higher than before treatment,the difference was statistically significant (t =24.298,25.546,18.737,15.733,14.284,14.886,9.337, 9.402,all P <0.05).The SNCV and MNCV in the observation group were significantly higher than those in the con-trol group (t =9.119,11.103,7.429,6.352,all P <0.05).The markedly effective rate of the observation group was 48.8% (42 /86),the total effective rate was 90.7% (78 /86),which were higher than those of the control group,the differences were statistically significant (χ2 =9.010,7.937,all P <0.05).The incidence rate of adverse reaction of the observation group was 5.8% (5 /86),which of the control group was 6.5% (5 /77),the difference was not statis-tically significant (χ2 =0.033,P >0.05).Conclusion In the treatment of diabetic peripheral neuropathy,the com-bined treatment of mecobalamin and salvia miltiorrhiza ligustrazine has better curative effect and low incidence rate of adverse reaction,with good clinical application value.

Chemokine is a small protein which plays an impor-tant role in men's physiological function.It has chemotactic ac-tivity and is often secreted by immune cells and glial cells like microglia or astrocytes.Through the effect of chemokine recep-tors on target cells,various immune cells can achieve directional migration and play an important role in the diseases related with immunity and inflammation.CCL2,also known as monocyte chemotactic protein-1 (MCP-1 ),is one member of chemokine CC subfamily (βsubfamily).It can chemokine monocytes, macrophages and T lymphocytes to affect their phagocytosis func-tion and produce antibodies to combat invading microorganisms. In recent years,it has been found that CCL2 plays a key role in the occurrence and development of the problems concerning cen-tral nervous system and immune system as well as cancer, AIDS,leukemia,diabetes and other diseases.This thesis is to give an elaboration on the latest research on CCL2 and the rele-vant diseases.

The process of late lung development is disturbed in bronchopulmonary dysplasia (BPD).One of the keys in late lung development is secondary septation, in which secondary septa arise from primary septa, producing plenty of small alveoli, which significantly increase the surface area of gas exchange.Secondary septation,together with architectural changes to the vascular structure of the lung which minimize the distance between the blood and the inspired air, are the targets of late lung development.BPD is a disease of premature infants in which development of the alveoli is stunted caused by many factors including volutrauma,inflammation,and oxygen toxicity.Compared with early lung development, the later development of the immature lung remains unclear.This paper is to emphasize remarkable latest research of arrested late lung development and BPD.

Objective To evaluate the short-term effect of elemene combined with transcatheter hepatic arterial chemoembolization (TACE) interventional therapy for the treatment of moderate and advanced liver cancer.Methods A total of 63 patients with moderate and advanced liver cancer were randomized into test group(31 cases) and control group(32 cases). Both groups were given TACE, and additionally, the test group was given intra-arterial infusion of Elemene Emulsion(400-600 mg/m2)together with MAO(Mitomycin C 4-6 mg/m2 , adriamycin 20-40 mg/m2, Oxaliplatin 50-85 mg /m2), and the control group was given intra-arterial infusion of MAO. Short-term effect was evaluated by the clinical outcomes of tumor size, progression-free survival(PFS), total survival rate and adverse reactio n. Results(1)The overall response rate(ORR) in the test group was superior to that in the control group, and the difference was statistically significant(P<0.05) .(2)PFS in the test group covered 125 days, and that in the control group covered 118 days, the difference being significant (P<0.05); the median survival time(MST) in the test group was 257 days, and that in the control group was 214 days,the difference being insignificant(P>0.05).(3) No severe toxic or side effect was found in t he twogroups, the difference being not significant(P>0.05). The test group tended to have milder adverse reaction. Conclusion Intra-arterial infusion Elemene Emulsion combined with TACE interventional therapy is effective in increasing ORR, prolonging PFS, promoting adverse reaction endure and relieving symptoms of weakness, abdominal distension and pain.

Radiation therapy plays an important role in the multidisciplinary treatment of early stage breast cancer. While breast conservative treatment has become an established strategy, recent clinical investigations focus mainly on the possibility of modification to the standard practice, including the significance of tumor bed boost after whole breast irradiation, the criteria for low-risk patients not to receive adjuvant radiotherapy after breast conservative surgery and the feasibility of partial breast irradiation. Post-mastectomy radiotherapy to the chest wall and regional lymph nodes in high-risk patients has been proved to reduce the local-regional recurrence by 2/3. However, only a few trials support the improvement of survival, and significant controversy exists concerning the role of post-mastectomy radiotherapy in intermediate-risk patients. Current review summarizes the advances and controversies stated above for the treatment of early stage breast cancer.

The curriculum for general practitioner training does not include much knowledge on medical humanities except for medical ethics,which can not meet the requirement of general practitioners' defined duty.This article analyzes the necessity of adding social psychological skills to the training and assessment of general practitioners from the following aspects of the nature of general practitioners' duty,and the disadvantages of medical humanities education in current Chinese medical universities.Then the proposition of this system is also presented.

Unilateral facet dislocation of the lower cervical spine is an important subgroup of cervical spine injuries,accounting for from 12％ to 16％ of all cervical spine injuries.Unilateral facet dislocation occurs the most commonly at the C5-6 level,and is closely related to the anatomic and morphometric features of the cervical facet.This injury has been attributed to combined flexion and rotation,but it remains unclear whether flexion or rotation is the component of greater importance.Its treatment includes nonoperative and operative measures but optimal treatment has not been established.It is generally accepted that a recommendable treatment protocol begins with closed reduction and proceeds depending on whether the closed reduction succeeds and traumatic disc herniation is present or not.
