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 screen the differentially expressed genes between hypertrophic scar of burn and normal skin using gene microarray, to find out the genes of significantly different-expression and to analyse the roles of them in development of hypertrophic scar. Methods The total DNA and RNA from 4 hypertrophic scar samples and 4 normal skin were isolated and purified to mRNA by oligotex. They were reversely transcribed to cDNA with the incorporation of fluorescent dTUP to prepare the hybridization probes. Then, the mixed probes were hybridized to the cDNA chip and scanned for the signals and found differences between scar and normal skin. Results Among 4000 target genes, there were 378～451 genes once and 114～152 third times significantly different between hypertrophic scar and normal skin and 97 different-expressed genes in all 4 cases. Conclusions There are differences of gene expression between hypertrophic scar and normal skin screened by microarray. As the scanned cases increase, the common differentially-expressed genes become less and less, which may involve in the development of hypertrophic scar.

[Objective]To investigate the possibility of using poly(hydroxybutyrate-co-hydroxyvalerate)(PHBV)as scaffolds for cartilage tissue engineering and to compare the engineered cartilage generated in vitro with those in nude mice modles.[Method]PHBV porous scaffolds were fabricated using a compression moulding,thermal processing and salt particulate leaching methods.Chondrocytes isolated from articular cartilage were seeded into porous PHBV scaffolds.After incubation for 2 weeks in vitro,chondrocytes-PHBV constructs were implanted subcutaneously in the dorsum of athymic nude mice.Control groups were established by subcutaneous implantation of PHBV alone.The implants harvested after in vivo incubation of 4 and 8 weeks and cell-scaffolds cultured in vitro for 6 and 10 weeks were respectively examined histologically.Chondrocytes cultured for 3,7 and 14 days on the scaffolds were examined by SEM.[Result]SEM showed that chondrocytes could aggregate and synthesize extracellular matrix on PHBV scaffolds.Both specimens harvested from nude mice and those cultured in vitro demonstrated new cartilage formation,while characteristics of the engineered cartilage generated in vivo were more typical.Those from control groups showed no cartilage formation.[Conclusion]PHBV can be used as scaffolds for cartilage tissue engineering and nude mice modle seems to facilitate chondrogenesis compared with that in vitro system.

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
