In China, health care system is not perfect,the trust is lack between doctors and patients. Introdu-cing medical social workers to hospitals is to manage social resources as a whole, optimize medical treatment service process,enhance the quality of medical service, and relieve the pressure of doctors and nurses. Under this back-ground, this paper gave an overview of the medical social work and its contents. Then, it analyzed the necessity of introducing medical social workers to hospitals and pointed out the existing plight of medical social work. Finally, it put forward the suggestions and countermeasures to promote medical social work.

AIM: To compare the effect of small incision extracapsular cataract extraction and phacoemulsification on corneal endothelial cells and explore the differences between these two most commonly used surgeries for grade Ⅱ-Ⅲ lens nucleus. · METHODS: Retrospective study. We retrospectively evaluated the data of age-related cataract patients who had completed surgery in our hospital between June 2013 and December 2015. There were 84 eyes of 84 patients. The corneal endothelial cell density of all the patients were greater than 2000/mm2 and lens nucleus were gradeⅡ- Ⅲ. The patients were divided into manual small incision cataract surgery ( MSICS ) group and phacoemulsification ( Phaco ) group. MSICS group included 42 cases (42 eyes) and Phaco group included 42 cases ( 42 eyes ) . Postoperative evaluations were performed at 1d, 1wk, 1mo and 6mo and included uncorrected visual acuity ( UCVA ) , corneal endothelial cell density and the proportion of hexagonal cells. · RESULTS: There were no statistically significant differences of the two groups in preoperative basic data, UCVA, corneal endothelial cell density and the proportion of hexagonal cells, nuclear classification. The postoperative UCVA were significantly improved in both groups (x2=148. 01, P<0. 001; x2=165. 97, P<0. 001). The postoperative UCVA were on the rise as time goes on. The postoperative corneal endothelial cell density was obviously reduced in both groups compared with the preoperative (F=37. 74, P<0. 001; F=24. 56, P<0. 001). The proportion of hexagonal cells in Phaco group was declined at 1d (P=0. 002) after the operation and returned to baseline by 1wk (P=0. 894) after surgery. There was no significant difference between the two groups in UCVA, corneal endothelial cell density and the proportion of hexagonal cells at each observation point (P>0. 05). ·CONCLUSION: Manual small incision cataract surgery and phacoemulsification can indiscriminately improve UCVA and decrease the density of corneal endothelial cells. However, the change of hexagonal cells proportion was not obvious. These two surgeries for cataract patients with corneal endothelial cell density greater than 2000/mm2 , grade Ⅱ-Ⅲ lens nucleus have similar efficacy and safety.

Objective: To observe the clinical efficacy of lung-clearing and spleen-strengthening tuina on exogenous cough in children. Methods: A total of 77 children with exogenous cough that met the inclusion criteria were randomly divided into a treatment group and a control group according to the random number table, with 39 cases in the treatment group and 38 cases in the control group. The routine lung-clearing manipulation was used in the two groups, while the spleen- strengthening manipulation was added in the treatment group. Both groups were treated once a day, 5 times as a course of treatment. After one course of treatment, the symptom score and clinical efficacy were observed. Results: There were one dropout in the treatment group and 2 dropouts in the control group. Therefore, a total of 74 cases were finally included in the analysis, with 38 cases in the treatment group and 36 cases in the control group. After treatment, there was a statistically significant difference in cough score between the two groups (P<0.05). There was a statistically significant difference in the score of poor appetite between the two groups (P<0.05). After treatment, the total effective rate was 89.5％ in the treatment group versus 75.0％ in the control group, showing a statistically significant difference (P<0.05). Conclusion: The therapeutic efficacy of lung-clearing spleen-strengthening manipulation is better than that of lung-clearing tuina manipulation alone for children with exogenous cough; regulating spleen and stomach can improve the curative efficacy of exogenous cough in children.

Objective To investigate the effect of MT-1 and MT-2 in liver damage in chronic inorganic arsenate exposure mice and to explore the mechanism of arsenic-induced liver damage. Methods The male Kunming mice were randomly divided into control and exposed groups. The control group was given ordinary feed and tap water. The exposed group was given ordinary feed and 300 mg/L of sodium arsenite solution by drinking water. After 10 months of treatment, the activity of serum alanine aminotransferase (ALT), aspartate aminotransferase(AST) and globulin (Glb) content were determined. The total RNA was extracted by the TRIzol-phenol-chlorofor-method from the liver tissue. The quantity of the RNA was determined by spectrophotometry and its purity was judged at a ratio of A260/A280. Then real-time PCR(RT-PCR) was used to measure the mRNA expression of MT-1 and MT-2. Results Compared with the control group, serum ALT, AST activity and Glb content were higher and the MT-1 and MT-2 mRNA content was lower in the exposed group (P

Objective To evaluate the effects of a health education project on prevention and control of iodine deficiency disorders.Methods From January to June 2011,an investigation was conducted using combined unified questionnaire in 9 counties on target population,and 3 townships were chosen in each project county.Health educational activities were carried out in grade 5 classes in the central primary school.In the meantime,3 villages were chosen in each selected township where the health educational activities in the community were carried out.Before and after the health educational activities,questionnaire surveys on knowledge of iodine deficiency disorders were conducted in each project county.Thirty students in one class of grade 5 in the central primary school were selected,and 15 women of childbearing age near the central primary school were selected too.The health education content included but not limited to:popular science films about the knowledge on endemic disease prevention and public-interest ads were broadcasted by radio,television,newspapers and other media in the project counties,aiming at spreading knowledge on prevention and treatment of endemic diseases.In each of the project township government and village committee locations,posters,banner pieces and slogan suspensions about knowledge on endemic disease prevention were posted or put up.In the project rural hospitals,a special bulletin boards was set up,and in the village clinics (rooms),posters were put up,to carry out a training program for women of childbearing age on endemic disease prevention.In primary schools,students in grades 4 to 6 were given a class about knowledge on prevention and treatment of iodine deficiency disorders,aiming at their transferring the learned knowledge to family members.Results A total of 2678 persons were investigated before and after the health education.After health education,the rate of knowledge(the correct answer rate) on iodine deficiency disorders increased from 69.04％ (1920/2781) to 94.08％ (2622/2787,x2 =580.63,P ＜ 0.05) among primary school students,and 74.76％(924/1236) to 92.60％(1139/1230,x2 =143.59,P ＜ 0.05) among women of childbearing age.Conclusions The rate of knowledge awareness in the students and the women of childbearing is increased significantly after the health educational activities.Systematic and targeted health education activities are effective measures in prevention and control of iodine deficiency disorders.

By direct communication between clinicians and laboratorians, obstacles between clinical work and laboratory diagnosis were unequivocally found at an academic conference. Many clinical physicians feel disappointed and frustrated at the laboratory diagnosis by semen analysis and frankly express their expectations, as to recognize the role and significance of laboratory diagnosis, understand the value of routine semen analysis, work out the puzzles in the analysis of sperm morphology, fulfil the requirements for the identification of cells in semen, and obtain responses from and initiate discussions among laboratorians about the relevant questions. Both laboratorians and clinicians are appealing for strengthened management and earlier establishment of national standards and operating specifications for laboratory diagnosis by semen analysis.
