OBJECTIVE: To study the bacteriostatic action of Yiqing capsule against propionibacterium acnes and staphylococcus epidermidis in vitro.METHODS: Propionibacterium acnes and staphylococcus epidermidis were cultured by microplating method and routine plating,and the bacteriostatic action of different concentration of Yiqing capsule and its main components against propionibacterium acnes and staphylococcus epidermidis were determined by measuring their MICs.RESULTS: The MICs of Yiqing capsule and Scutellaria baicalensis extractum against propionibacterium acnes and staphylococcus epidermidis were 0.98 mg?mL-1 and 1 mg?mL-1,respectively,whereas the MICs of Radix et Rhizoma Rhei and Rhizoma Coptidis Scutellaria extractum against propionibacterium acnes and staphylococcus epidermidis were 1.96 mg?mL-1 and 1 mg?mL-1,respectively.CONCLUSION: Yiqing capsule showed satisfactory bacteriostatic action against the major pathogenic bacteria of acne.

Objective To summarize the strategies for nursing of skin flaps after 72 hours' transplantation of femoral skin flap for repairing soft tissue defect in lower extremity.Method One hundred and sixty trauma patients with lower extremity soft tissue defect underwent transplantation of femoral skin flap for repairing.The skin flaps were nursed within 72h after transplantation.Results The skins flaps in 160 patients receiving to repair tissue defect of lower limbs all survived.Within 72 hours after operation, 12 patients suffered from vascular crisis, which were cured after pertinent treatment.Conclusions For the patients receiving to repair tissue defect, the skin flaps should be carefully nursed. Meanwhile, preoperative psychological nursing, postoperative pain nursing and health education are critical for the survival of skin flaps.

To combine "the rule of military medical measurement" with the current situation of medical treatment quality control, the foundation, important component and necessary condition of medical treatment quality control was described. Some idiographic advices of intercoordination and communication in medical measurement institution, the direction and training of special technique, and how to develop compulsion coerciveness checking in base course were given. These are valuable for insuring medical treatment facility in hospital.

Objective To establish an evaluation index system for the quality and safety of the specialized nursing care in cardiovascular medicine. Methods To screen and evaluate the safety quality evaluation index via a group discussion with Delphi method and analytic hierarchy process referenced to the literatures from the evaluation index of domestic nursing safety quality (NSQ)and on the base ofthe factor quality- quality of links-final quality3-dimensional quality structure theory by Donabedian. Results The first and second round of expert consultation and the recovery rate were 97.05% (33/34) and 94.12% (32/34) respectibely, the effective rate was 100%;The authoritative coefficient of expert of the safety quality evaluation index of the specialized nursing care is 0.867 and 0.879 respectively. In the first round, the average of the importance rating is 3.50-5.00, the standard deviation is 0-0.042 and full mark rate is 34.10%-100%. In the second round, the average of the importance rating is 3.80-4.70, the standard deviation is 0~0.047 and full mark rate is 31.60%-100%. The fluctuation degree of the first round is more than 0.10 with a low coordination degree. However, the fluctuation degree of the second round result is less than 0.10. The coordination coefficients from all qustionnair scores by experts in the two roudns are 0.169 and 0.286. The difference was statistically significant according to the chi-square analysis (X2=6.842, P=0.002). The NSQ evaluatin index included 3 first degree indexes (weight coefficient including 0.2684,link qualing 0.6144,and quality 0.1172),16 second degree indicators (weight coefficient 0.034~0.0859) and 61 third degree indexes ( weight coefficient 0.034~0.0859) and 61 third degree indexes (weight coefficient 0.0052~0.0412). Conclusions This paper preliminary established a specialied NSQ evaluation index with factor quality- quality of links-final quality 3-dimensional quality structure in the field of cardiovascular medicine, which is based on Delphi method and analytic hierarchy process. NSQ provides a measurement tool for nurses in CME.

Objective: To investigate the effect of ceramic bovine bone (CBB) combined with hydrogel complex (CBB/HG), ?-tricalcium phosphate (?-TCP) combined with hydrogel complex(?-TCP/HG) on the osteogenesis of bone marrow stromal cells (MSCs) in vitro. Methods: MSCs(induced by 50 mg/L ascorbic acid,10 -8 mol/L dexamethasone and 0.01 mol/L ?-sodium glycerylphosphate) were cultured on CBB/HG , ?-TCP/HG,CBB and ?-TCP respectively. 5 and 10 days after set up, marrow stromal cell attachment and morphology were observed by scanning electronic microscope, the proliferation of the cells was evaluated by cell counting, Alkaline phosphatase(ALP) activity was tested,typeⅠcollagen synthesis were examined by immunohistochemistry stainning. Results: On day 5 and 10 the marrow stromal cells on CBB/HG and on ?-TCP/HG were significantly more than those on CBB or ?-TCP. TypeⅠcollagen synthesis and ALP activity of the cells on CBB/HG and ?-TCP /HG were not different but significantly higher than those on CBB or ?-TCP. Conclusion: CBB/HG and ?-TCP /HG may stimulate bone marrow stromal cell proliferation, differentiation and extracellular matrix synthesis.

Objective:To investigate Bcl-2 and Bax gene expression in acute myelogenous Leukemia and the relationship between Bcl-2/Bax ratio and drug resistance.Method:Expression of Bcl-2、Bax was detected by immunohistochemical method while drug resistance of AML was detected by cell culture and MTT assay.Results:A high expression of Bcl-2 and a low expression of Bax were detected in AML,respectively,and the ratio between Bcl-2 and Bax was significantly higher than that in normal control (P＜0.01). The ratio in those who are resistant to chemotherapy was significantly higher than that in those sensitive to chemotherapy (P＜0.05).The responsiveness to chemotherapy of those with a high ratio was poorer than thos with a low ratio (P＜0.05).Conclusion:The alteration of Bcl-2 and Bax played certain role in the development of drug resistance in AML,the test of Bcl-2/Bax ratio may have great significance in choice of chemotherapeutic agents and also provide important information for outcome prediction.

ObjectiveTo explore the effect of psychological care and community revisit on preven-tion of postpartum depression. Methods300 cases of pregnant women were randomly divided into the intervention group and the control group with 150 cases in each group. The intervention group took psycho-logical care and community revisit, the control group received conventional care. The incidence of missing follow- up and depression in the two groups were compared using χ2 test. ResultsThe incidence of miss-ing follow-up and depression in the intervention group was significantly lower than those of the control group. ConclusionsPsychological care and community revisit can significantly reduce the occurrence of postpartum depression.
