OBJECTIVE:To compare economical efficiency of 4 therapeutic regimens for pediatric perianal abscess. METH-ODS:By retrospective study method,85 children were divided into group A(18 cases),B(10 cases),C(14 cases)and D(43 cases)according to different therapeutic regimens. They were given amoxicillin-flucloxacillin,flucloxacillin,cefathiamidine and ce-famandole 100 mg/(kg·d) intravenously for 5-7 d,respectively. Clinical efficacies and the occurrence of ADR were compared among 4 groups. The economical efficiency of 4 therapeutic regimens were analyzed by the method of cost-effectiveness analysis. RESULTS:For group A,B,C and D,the cure rates were 77.78%,80.00%,57.14% and 90.70%,that of group C was signifi-cantly lower than those of other 3 groups,with statistical significance(P<0.05). No significant ADR were found in 4 groups. The costs were 3 600.86,2 913.92,3 416.19 and 2 981.97 yuan,and the cost-effectiveness ratios were 46.30,36.42,59.79 and 32.88. The incremental cost-effectiveness ratios of group A,C and D to group B were -309.43,-21.97 and 6.36. The results of cost-ef-fectiveness analysis were supported by sensitivity analysis. CONCLUSIONS:For pediatric perianal abscess,cefamandole shows the best cost-effectiveness;but the therapeutic duration and total cost of flucloxacillin therapeutic regimen is shorter and lower. Thera-peutic regimen should be selected according to children’s condition.

Objective To investigate whether and how regulatory T cells(Tr) affect macrophages foam-cell formation, and thereby investigate the mechanism of Tr in the development of atherosclerosis. Methods Tr were isolated from lymphocyte suspensions by magnetic cell sorting-column and analyzed by flow cytometry. Macrophages were cultured alone, with CD4~+ CD25~+ T, or CD4~+ CD25~- T cells in the pres-ence of oxLDL for 48 h to transform macrophages into foam cells. Oil red O staining and cellular lipid meas-urement were used to identify macrophage foam cell formation. Semi-quantitative PCR, quantitative real-time PCR and Western blot analysis were carried out to explore the mechanism of Tr-mediated suppression on macrophages foam cell formation. Results Foam cell formation, as identified by oil red O staining, was readily apparent in cells treated with CD4~+ CD25~- T cells and without T cells. After treatment with Tr, a marked decrease(13.9% ± 5.6% ) in foam cell count was observed, compared with untreated cells(13.9% ±5.6% vs 52.9% ± 10.4%, P<0.001 ) or CD4~+ CD25~- T-treated cells(13.9% ± 5.6% vs 53. 1% ± 17.2%, P<0.001 ), 52.9% ± 10.4% and 53.1% ± 17.2%, respectively (P<0.001). The similar effect of Tr was obtained when extracted oil red O and measured by a spectrophotometer. Cholesteryl ester ac-cumulation also used to quantify foam cell formation. Compared with untreated (no T) and CD4~+ CD25~- Tr-treated macrophage cells (CD25~-), the lipids accumulation in CD4~+ CD25~+ Tr-treated macrophage foam cells(CD25~+) was significantly reduced. Total cellular cholesterol and cellular cholesteryl ester was siginifi-cantly reduced in CD25~+ cultures relative to no T[TC(total cholesterol): 57.46 ± 17.92 vs 159.48 ± 16.38, P<0.01 ; CE(esterified cholesterol): 26.68 ± 8.88 vs 102.54 ± 16.67, P<0.001] or CD25~- (TC: 58.50±7.00 vs 150.55±25.11, P<0.01; CE: 26.68±8.88 vs96.90 ± 11.95, P<0.001) cul-tures. Moreover, PCR and Western blot analysis showed that the expression of both CD36 and SRA in Tr-treated macrophage foam cells was significantly down-regulated. Conclusion Results collectively suggest that CD4~+ CD25~+ Tr cells may inhibit macrophage foam-cell formation, which is largely attributed to a down-regulated expression in scavenger receptor in Tr-treated macrophage foam cells.

Synergistic antitumor effects of HB (berberine alpha-hydroxy-beta-decanoylethyl sulfonate, houttuyn berberine) with HCPT (hydroxycamptothecine), and its correlative mechanism were studied in vitro. MTT assay was employed to determine the cytotoxicity of HB combined with HCPT in tumor cells culture in vitro, IC50 and combination index (CI value) were used to evaluate the synergistic effects. The supercoiled DNA relaxation mediated by topoisomerase I & II was measured by agarose gel electrophoresis assay, and influence of HB was detected. The results showed that HB could inhibit the proliferation of tumor cells (SGC-7901, SW1116 and SW480) in vitro, and the inhibition ratio was increased, IC50 was reduced when combining with HCPT. CI value of the two drugs was less than 1 in HepG2, SW480, SGC-7901 and SW1116 cells. The lowest value was 0.447, 0.626, 0.161 and 0.178 in these tumor cells, respectively, further indicating HB has synergistic action with HCPT on suppressing tumor proliferation. The agarose gel electrophoresis assay showed HB can inhibit topoisomerase I & II activity of SW480 cells at the concentration of 2.0-8.0 mg x L(-1). HCPT is a typical inhibitor of topoisomerase I , the synergistic action between HCPT and HB on suppressing tumor proliferation is perhaps related to the congenerous inhibition of topoisomerase.

To investigate the cell proliferation inhibition and apoptosis induced by berberine a-hydroxy f-decanoylethyl sulfonate (HB) on MDA-MB-231 cells in vitro, and the inhibitory effect of HB on the expression of poly adenosine diphosphate RNA polymerase (PARP), MTT assay was used to detect the viability of MDA-MB-231 cells and cell cycle was examined by flow cytometry. The results showed that HB could significantly inhibit the proliferation of MDA-MB-231 cells, and mildly arrested cell cycle progression at S phase. The IC50S for 24, 48 and 72 h treatment were 4.65, 1.46 and 0.75 mg.L-1 (7.55, 2.37 and 1.22 micromol.L-1), respectively. Annexin V-FITC/PI double staining assay showed that HB increased apoptotic ratio of MDA-MB-231 cells. Western blotting analysis showed the expressions of procaspase-3, procaspase-9 and PARP were decreased after HB treatment, while their fragment increased. The results suggest that HB can inhibit the growth and induce apoptosis of MDA-MB-231 cells, which may be associated with inhibition of the expression of procaspase-3, procaspase-9 and PARP.

Objective To investigate the therapeutic effect of bundle treatments for critically ill patients with pulmonary tuberculosis and respiratory failure (RF).Methods A prospective study was conducted, including 56 patients with pulmonary tuberculosis and RF necessary for invasive mechanical ventilation admitted into Department of Critical Care Medicine of the Fourth People's Hospital of Nanning City from January 2013 to December 2014 as the observation group to be treated by bundle treatments. A series of treatments and cares were given to the critically ill patients, such as invasive mechanical ventilation, application of antibiotics by experience within the first hour, supportive treatment targeted to hemodynamics in early stage, correction of brain dysfunction, effective therapy for tuberculosis, establishment of enteral nutrition in early stage and prevention of ventilator-associated pneumonia (VAP), etc. All the above treatments were completed one by one in 6 hours to 12 hours. Meanwhile, 42 patients who hospitalized from January 2011 to December 2012 and treated with conventional targeted therapy were designed as the control group. The changes of vital signs, blood routine test, respiration, liver, kidney, etc organ functions, the improvement of acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, expected mortality and sequential organ failure assessment (SOFA) score, the incidence of VAP, cure and improvement rate, mortality, duration of invasive mechanical ventilation, the length of stay in intensive care unit (ICU) were compared between the two groups after treatments.Results There were no statistically significant differences in the comparisons between the two groups before and after treatments in temperature, white blood cell count (WBC), blood glucose, total bilirubin (TBil), alanine transaminase (ALT), albumin (Alb) and cholesterol level (allP > 0.05), except the platelet (PLT) count in observation group was higher than that in control group before treatments. After treatments for 72 hours, in the two groups, the heart rate (HR), respiration rate (RR), APACHE Ⅱ score and expected mortality were lower than those before treatments, while the arterial partial pressure of oxygen (PaO2) and oxygenation index were higher than those before treatments. There were no statistically significant differences in pH value, PLT, arterial partial pressure of carbon dioxide (PaCO2) and SOFA score before and after treatments in the control group (allP > 0.05). In the observation group, after treatments, the pH value was increased compared with that before treatments, while PLT, PaCO2 and SOFA score were decreased compared with those before treatments (allP < 0.05). The degrees of improvement of PaCO2 and oxygenation index in the observation group were superior to those in the control group [PaCO2 (mmHg, 1 mmHg = 0.133 kPa): 43.32±9.10 vs. 56.10±9.39, oxygenation index (mmHg): 330.60±100.98 vs. 245.65±83.20, bothP < 0.05]. After bundle treatments, compared with control group, the incidence of VAP was decreased [16.07% (9/56) vs. 33.33% (14/42),P < 0.05], improvement and cure rate was increased [78.57% (44/56) vs. 59.52% (25/42),P < 0.05] and mortality was decreased significantly in observation group [10.71% (6/56) vs. 28.57% (12/42),P < 0.05]. The duration of invasive mechanical ventilation (days: 9.15±3.59 vs. 16.96±13.44) and the length of stay in ICU (days: 13.30±4.24 vs. 23.00±15.03) in the observation group were shorter than those in the control group, but no statistically significant differences were found (bothP > 0.05).Conclusion The bundle treatments can effectively reduce the incidence of VAP and elevate the improvement and cure rate in patients with pulmonary tuberculosis complicated with RF.
