Objective To explore the application of PBL (Problem - Based learning) mode in fami-ly peritoneal dialysis training to improve the teaching effects of peritoneal dialysis training. Methods The PBL mode was applied in every peritoneal dialysis training lesson, the teaching effects were evalued af-ter a lesson immediately. Results The PBL mode would be helpful to inspire patients' and their family members' interest to learn the knowledge of peritoneal dialysis training.It was also helpful in knowledge un-derstanding, knowledge mastering and establishment of treatment confidence. Conclusions The PBL mode was an important way to improve the teaching effects of peritoneal dialysis training and realize the teaching objective. It is worth applying in practice of peritoneal dialysis training.

Objective To analyze results of bacterial infection distribution and drug sensitivity monitoring in 414 patients with open extremity injuries caused by Wenchuan earthquake so as to provide advices for guiding utility of antibiotics in treatment of patients injured in natural disasters. Methods Bacterial culture of wound secretion substance and drug sensitivity monitoring were done in 414 patients with open extremity injuries. Results There were 12 patients (2.9%) with G+ coccobacteria, 66 (15.9%) with G- bacillus, 2 (0.5%)with G+ bacillus, 6 (1.5%) with multiplicitas infection(5 with dual infection and I with triplication infection). Main pathogenic bacteria were as follows: (1)G+cocco- bacteria including Staphylococcus epidermidis, Staphylococcus aureus and anthropo-staphylococci ; (2) G- bacillus including Aerobacter cloacae, banmanii, escherichia co]i, aerugo pseudomonas, proteusvul- gaffs and Ewingella americana. (3)G+ bacillus including bacillus subtilis. The drugs with high sensi0tivi- ty to G+ coccobacteria included vancomycin, rifampin, levofloxacin and cidomycin, but those with low sensitivity to G+coccobacteria included penicillin, ampicillin and erythremycin. The drugs with high sen- sitivity to G- bacillus included imipenem, amikacin, levofloxaciu and tenebrimycin, but those with low sensitivity to G-bacillus included ampicillin and piperacillin. Conclusions Patients with open ex- tremity injuries caused by earthquake have rather high bacterial infection rate, involving many kinds of in- fection strains. Therefore, we should do bacterial culture and drug sensitivity monitoring of wound excre- tion substance as early as possible to guide rational use of antibiotics.

BACKGROUND: With further understanding of deep venous thrombosis(DVT)following total hip replacement,reduction and prevention of DVT has become hot topic in clinical studies.The reports of DVT formation factors remain controversial due to small samples,little statistical significance,confusion of basic experimental and clinical results and lacks of science.OBJECTIVE: To explore the causes and factors for the early DVT following total hip replacement and summarize measures to prevent and treat early DVT to reduce incidence of complications.METHODS: A total of 1780 cases of primary total hip replacement operation were analyzed retrospectively.The statistical indexes included sex,age,body mass,other system disease,previous hip joint operation,anesthesia,operative time,prosthetic fixation,blood transfusion,postoperative functional exercise,antithrombotics,and complication.Standardized database was built and analyzed by SPSS(version 13).Regression analysis was performed using Binary Logistic Regression.RESULTS AND CONCLUSION: Of 1780 cases,136 had DVT.Age,other system diseases,anesthesia,prosthetic fixation,blood transfusion,postoperative functional exercise and antithrombotics were correlated with early DVT(P < 0.05).Old age,hypertension or diabetes,general anesthesia,fixation of bone cement,whole blood transfusion were the risk factors for early DVT following total hip replacement,while postoperative functional exercise and antithrombotics were the protective factors for DVT.The incidence rate of early complications can be reduced by the methods such as dealing with perioperative treatment carefully,effectively controlling the chronic diseases,efficient evaluation before surgery,precise manipulation,and the postoperative prophylactic treatment and nursing.

Objective To investigate the effect of routine ultrasound examination and interventional treatment of absolute alcohol in different types of liver cancer.Methods Thirty cases of liver cancer patients who were treated in the 3rd People' s Hospital of Yangquan from May 2010 to May 2014 were selected as ours subjects.They were performed ultrasound exam.The ultrasound characteristic was recorded.Patients were divided into intrahepatic cholangiocarcinoma (ICC) group (11 cases),hepatocellular cholangiocarcinom (HCC) group (14cases) and mixed cholangiocarcinoma group(5 cases) based on pathology results.Nine HCC postoperative recurrence patients and 7 ICC postoperative recurrence patients were treated with absolute alcohol and the clinical effect was observed.Results There were significant differences in the three groups in terms of gender,boundary definition and tumor location (x2 =8.01,6.16,7.32 ; P < 0.05).While the distribution of ultrasound echo intensity was not statistically significant(x =3.44,P > 0.05).The effective rate of interventional treatment of absolute alcohol in HCC patients was 88.89%,and 42.86% in ICC group,and the difference was statistically significant (x2 =3.88,P < 0.05).Conclusion The ultrasound characteristics of different pathological liver cancer are different.Ethanol interventional therapy on HCC patients is significantly better than the effect of ICC patients,suggesting that ICC postoperative recurrence patients can be treated combined with other methods to help improve the effect.

AIM:To investigate the process parameters of adsorbing and separating the total flavones of Radix et Rhizoma glycyrrhiae and its assay. METHODS: Chalcone that flavanone in Licorice root was converted into in alkaline condition was adopted as index and niaringoside as control,through polyamide treatment,alkaline colorimetty was used to determine chalcone content. RESULTS: Under the condtion,namely, ratio of quantity of Licorice root to polyamide was 2:1,ratio of column diameter to column heighth was 1:7,70%ethanol used to eluate,flavone extract was up to 45%with 90%eluting yield.The recoveny of assaying was 98.17%(RSD=2.00%). CONCLUSION: The purification and assay of Licorice flavonoids are reliable and efficacious.

To study which subgroup of bone marrow derived cells formed myofibroblasts and the mechanism that transforming growth factor β1 (TGFβ1) regulates the formation of bone marrow derived macrophages into myofibroblasts during renal fibrosis.Chimeric mice were generated by lethally irradiation of C57 mice followed by transfusion of green fluorescent protein (GFP) labeled bone marrow cells.Complete marrow reconstitution was developed until 12 weeks after transplantation.The mice were randomly divided into Sham operation group,unilateral ureteral obstruction (UUO) 3 days group,UUO5 days group,UUO7 days group and UUO7 with TGFβ1 treatment group.Each group had four mice.Flow cytometry was used to evaluate cell components.Compared with Sham operation group the proportions of GFP + CD+14 oα-smooth muscle actin(α-SMA) + cells,GFP + CD+44 CD+105 α-SMA+ cells and GFP+ F4/80+ α-SMA+ cells in each UUO group were progressively increased and the transformation rate in UUO7 day group was the highest.The GFP+ F4/80 + α-SMA+ cells accounted for the largest population.TGFβ1 promoted the transformation of bone marrow derived macrophages into myofibroblasts.Compared with Sham operation group or UUO7 day group,the proportion of GFP+ F4/80+ α-SMA+ cells increased in UUO7 day TGFβ1 treatment group.Compared with Sham operation group (or UUO7 days group) the protein expressions of F4/80,oα-SMA,Collagen Ⅰ increased in UUO7 with TGFβ1 group.Bone marrow derived macrophages are considered as the main type of myofibroblast precursors during the development of renal fibrosis.TGFβ1 regulates the transformation of bone marrow-derived macrophages into myofibroblasts.This process contributes to progressive renal fibrosis and deterioration of renal function.
