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 compare the effect of allogeneic and autologous blood transfusion on postoperative immunoreaction in patients after spinal surgeries.Methods A total of 44 patients undergoing spinal operations were randomly divided into two groups.Allogeneic (n=22) or autologous (n=22) buffy-coat-depleted red cells were used in the patients during the operations.The serum levels of IL-6,IFN-?,and TNF-?were determined preoperatively and then re-measured 1 and 7 days after the operations. Results In theautologous group,both IFN-?and IL-6 increased after the oprerations,the level of IL-6 was significantly higher than that in the allogeneic group at days 1 and 7.The concentration of TNF-?did not change after the surgeries in the two groups. Conclusions By autologous blood transfusion,the serum levels of IFN-?and IL-6 can be increased significantly after spinal operation,meanwhile the concentration of TNF-?remains stable.The postoperative inhibitory effect of the procedure on immunocytokines is significantly weaker than that of allogeneic blood transfusion,indicating that autologous blood transfuion can protect or even increase immunofunction after spinal operation.

Objective To determine the effect of diffusion chamber for immune isolation and the proliferation of allogenic hybridoma within diffusion chamber in mice. Methods The hybridoma cell strain was established from SP2/0 cells and the splenocytes of BALB/c mouse by PEG mediate technique. The cells were injected peritoneally into BALB/c ( n =5) and C57 BL/6 (B6, n =5) mice. Diffusion chambers with microporous membrane containing hybridoma cells were implanted peritoneally into 5 BALB/c and 5 B6 mice. Results Within two months after peritoneal injection of the cell strain, four BALB/c mice developed bloody ascites and one developed abdominal tumor, but the B6 mice developed neither ascites nor tumor. After 30 and 101 days of the chamber implantation, the chambers were coated by omentum or mesenterium in all the animals of both strain groups and freshly formed blood vessels to the chamber membrane could be observed. Within the chambers, tumor developed, but the tumor could not fully fill the inner space of the chamber during the whole observation period. Conclusion The hybridoma cells established from SP2/0 cells and the splenocytes of BALB/c mouse may carry BALB/c MHC antigen. The diffusion chambers can effectively isolate immune rejection. Freshly formed blood vessels to the chamber membrane can support the cells within the chambers.

Objective:To investigate the effects of resuscitation with different fluids on hemodynamics,oxygen transport and extravascular lung water after acute hemorrhage in dogs. Method:Fifteen dogs were anesthetized and bled to a mean arterial pressure of 4.67 kPa to develop the hemorrhagic shock model.Then the animals were infused with one of three randomly selected fluid:lactated Ringer's solution, blood and polygeline.The terminal point of fluid resuscitation was at the level of PAWP of 2.0 kPa. Hemodynamics, oxygen transport and extravascular lung water values were measured. Result:colloids fluids infusion has more better efficacy and less extravascular lung water than crystalloids fluids infusion in hemorrhagic shock resuscitation,and polygeline infusion could restore hemodynamics better, meanwhile blood infusion could restore oxygen transport better.
