OBJECTIVETo observe the clinical effect of Sizhi-Xifang in the improvement of postoperative ankle function.

METHODSFrom Jan. 2006 to Mar. 2008,49 patients were divided randomly into treatment group and control group. The treatment group included 16 males and 8 females with an average age of (41.3 +/- 13.2) years, involving 13 cases of tye A, 9 of type B and 2 of type C based on AO classification. The control group included 15 males and 10 females with an average age of (38.2 +/- 10.9) years, involving 12 cases of type A, 10 of type B, 3 of type C. Minimal invasive percutaneous plate were used in each group. In treatment group 24 cases were treated with Sizhi-Xifang after the incisions were healed.

RESULTSThere were no incision infections, flaps necrosis, bone and plate exposure after treatment in two groups. All patients were followed-up for 4 to 16 months with an average of 8.6 months. According to Johner-Wruhs evaluation standard, there were 7 cases in excellent, 12 good, 5 in fair in treatment group and in control group there were 5 cases in excellent, 7 in good, 10 in fair and 3 in poor. The comparison of effect between two groups had significant difference (P < 0.05).

CONCLUSIONSizhi-Xifang is helpful to improve the ankle postoperative function.

Objective To evaluate the effect of sevoflurane on liver injury in a pig model of hemorrhagic shock.Methods Twenty-four Bama miniature pigs of both sexes,weighing 20-25 kg,aged 3-5 months,were equally randomized into 3 groups using a random number table:sham operation group (group S);hemorrhagic shock group (group HS);sevoflurane group (group Sev).Hemorrhagic shock was induced by withdrawing 40％ of blood volume from the right femoral artery within 15 min (30 ml/kg) in HS and Sev groups.The animals inhaled 2％ sevoflurane for 30 min after establishment of the model in group Sev.Before hemorrhagic shock (T0),and at 30,60,90,120,180 and 240 min after hemorrhagic shock (T1-6),blood samples were collected from the femoral artery for determination of plasma alaninc aminotransferase (ALT) and betaine-homocysteine S-methyltransferase (BHMT) concentrations (by enzymelinked immunosorbent assay).After blood sampling at T6,the animals were sacrificed,and the right lobes of livers were removed for examination of the pathological changes with light microscope.Results Compared with group S,the plasma ALT concentrations were significantly increased at T4-6,the plasma BHMT concentrations were significantly increased at T3-6 (P＜0.05),and significant liver pathological changes were observed in HS and Sev groups.Compared with group HS,the plasma ALT concentrations were significantly decreased at T4-6,the plasma BHMT concentrations were significantly decreased at T3-6 (P＜0.05),and the liver pathological changes were significantly attenuated in group Sev.Conclusion Sevoflurane can mitigate liver injury in a pig model of hemorrhagic shock.

Objective To evaluate the needs of performing a standardized communication skill training program for residents according to the differences in history taking mode of residents with different degrees and before and after the standardized training in Shanghai Changhai Hospital in 2010.Methods History taking modes of 81 residents in 2010 before and after the standardized training in Shanghai Changhai hospital were categorized.History taking modes were classified into:no effectiveness mode,traditional mode,disease-sickness mode and Calgary-Cambridge Guide mode.Distribution differences of history taking mode of residents with different medical degrees were analyzed by Fisher exact probability method (α =0.05).Distribution differences of history taking mode of residents before and after standardized training were analyzed by Pearson x2 test (α =0.05).Results 19.8％ residents took no effectiveness mode,53.0％ took traditional mode and 27.2％ used disease-sickness mode.There were significant differences in history taking modes among residents with different medical degrees (P =0.008).After training,history taking modes of residents were significantly changed (P=0.001),only 1.2％ residents used no effectiveness mode,59.3％ used traditional mode and 34.6％ used disease-sickness mode.But residents using the Calgary-Cambridge mode were not increased.Conclusions There are significant differences in history taking modes among residents with different medical degrees.History taking mode of residents changed after standardized training.But some of the residents still use non-optimal history taking modes; therefore a standardized communication skill training program might be needed in the future.

This study investigated the changes of CD4(+) CD25(+) regulatory T cells (Tregs) in peripheral blood of patients with hepatocellular carcinoma before and after transcatheter arterial chemoembolization (TACE). The proportion of CD4(+) CD25(+) Tregs among CD4(+) T lymphocytes in peripheral blood of 33 patients with hepatocellular carcinoma was determined by flow cytometry before, 1 week and 1 month after TACE. And 25 healthy volunteers served as control. One month after TACE, the patients were divided into two groups: 22 in group A, who were in stable condition or getting better; and 10 in group B, who were deteriorating. One patient died and was excluded. The results showed that the percentage of CD4(+)CD25(+) Tregs among CD4(+) T lymphocytes did not significantly change in the 33 patients 1 week after TACE as compared with that before TACE, however, the difference was significant (P<0.01) between the patients with hepatocellular carcinoma and the healthy subjects. The percentage of CD4(+) CD25(+) Tregs among CD4(+) T lymphocytes in group A 1 month after TACE was decreased significantly in comparison with that before and 1 week after TACE (P<0.01), whereas, that in group B was increased significantly 1 month after TACE (P<0.01). It was concluded that patients with hepatocellular carcinoma had a higher proportion of CD4(+)CD25(+) Tregs in peripheral blood. TACE did not significantly affect the level of CD4(+) CD25(+) Tregs within short time (such as 1 week). The proportion of CD4(+)CD25(+) Tregs in peripheral blood 1 month after TACE was related to the prognosis of hepatocellular carcinoma.
