Objective:To explore the efficacy and safety of amisulpiride at low dosage combined with clozapine in the treatment of refractory schizophrenia. Methods:Totally 160 patients with refractory schizophrenia were chosen from the psychiatric department of 4 hospitals during January to September in 2014 and randomly divided into the observation group and the control group with 80 cases in each. The patients were treated with clozapine plus amisupiride or clozapine plus placebo for 12 weeks. The positive and negative syn-drome scale ( PANSS) and treatment emergent side effect scale ( TESS) was used to respectively evaluate the efficacy and the adverse effects. Results:At the weekend of the 4th, 8th and 12th week after the treatment, the clinical efficacy in the observation group was sig-nificantly better than that in the control group (all P<0. 05). The total and every factors scores of PANSS after the treatment were sig-nificantly lower than those before the treatment in both groups ( P<0. 01), and the decrease in the observation group was more signifi-cant than that in the control group (P<0. 05 or P<0. 01). There was no significant difference in the incidence of adverse effects be-tween the two groups (P>0. 05). Conclusion:Amisulpiride at low dosage combined with clozapine can significantly improve the effi-cacy in the treatment of refractory schizophrenia without added adverse effects.

Objective To research the antiviral activity of artesunate (ART) in vitro fighting against both standard laboratory strains and ganciclovir(GCV)-resistance strains of human cytomegalovims(HCMV) and to explore whether fractionation dosage method can obviously enhance the antiviral effect of ART.Methods 1.Cytotoxicity assay to ART was performed by the use of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) colorimetry.The 0% toxic concentration (TC0) were determined,and median cytotoxic concentration (TC50) was calculated with Probit regression method.2.Antiviral activity assays of ART against HCMV:human embryonic lung fibroblast cells (HELs) were infected with standard laboratory strains and GCV-resistance strains of HCMV,respectively,after which virus was removed and overlays of dulbecco's modified eagle medium(MEM) containing different antiviral drugs were added to the wells.All cells were cultured continuously at 37 ℃ in a 50 mL/L CO2 humidified atmosphere for 7-10 days and the cytopathic effect (CPE) was observed under a microscope.When the degree of CPE was clear (+ + +-+ + + +),the values of absorbency at 490 nm of all cell wells were measured by MTT colorimetry.The cell survival rate (CSR)and drug inhibitory rate (IR) for HCMV were calculated.By Probit regression method,the median inhibitory concentration (IC50) of 2 drugs was calculated respectively.3.To explore whether fractionation dosage method could obviously enhance the antiviral effect of ART against HCMV,the experiment was divided into 3 groups and compared with GCV group,respectively:Group 1:ART antiviral compounds were added to cell layers by one dosage.Group 2:Total drug dosage was divided into 3 parts,and each part was added to cell layers once a day for 3 days.Group 3:Total antiviral compounds were divided into 6 and delivery 2 times a day.The values of absorbency at 490 nm of all cell wells were measured by MTT colorimetry.The CSR and viral inhibitory rates were calculated.All data were statistically analyzed by One-Way ANOVA analyzing using SPSS 18.0 statistical software.P value of <0.05 was considered to indicate statistical significance.Results 1.Cytotoxicity assay showed that cytotoxicity was not found in the relevant range of ART concentrations under 62.5 μmol/L.TC0 and TC50 value of ART were 62.5 μmol/L and 171.7 μmol/L.2.In concentration of 5 μmol/L,15 μmol/L and 30 μmol/L,ART and GCV could obviously inhibit growth of HCMV AD169 strains.There was no significant difference between them.The value of GCV IC50 was 3.49μmol/L,and the value of ART IC50 was 2.17 μmol/L.Treatment index (TI) of ART was 28.8,and GCV was 716.3.ART could still obviously inhibit growth of HCMV resistant strains,but GCV couldn't.Differences between them were statistically significant.The value of GCV IC50 to HCMV resistant strains was 44.4 μmol/L,and the value of ART IC50 was 2.5 μmol/L.3.Fractionation dosage method (2 times a day) of ART could improve the inhibition rate of virus significantly compared to that used once a day and single dose method.Difference was statistically significant(P < 0.01).GCV delivered as the same method had little different changes in virus suppression ratio(P > 0.05).Conclusions 1.Cytotoxicity was not found in the relevant range of ART concentrations under 62.5 μmol/L.2.ART could obviously inhibit growth of HCMV resistant strains and standard laboratory strains.3.Fractionation dosage method (2 times a day) of ART could improve the inhibition rate of virus significantly compared to that used once a day and single dose method.4.Because the action mode of ART is different from other anti-HCMV drugs,and ART has a high biological activity and fewer side effects,it is expected to become a kind of new antiviral drugs for HCMV infections.

Objective To explore the different expression of NF-κB in both K562 and its multidrug resistant cell line K562/A02 and discuss the mechanism of muhidrug resistance(MDR). Methods To detect the growing feature of the cells. Flow cytometry was used to analys the difference between the distribution profile of K562/S and K562/A02 cell. MTT colorimetry was used to determine the cytotoxic effect of adramycin, and expression of mdrl gene was detected by semi-quantitative reverse transcriptase poly-merase chain reaction (RT-PCR) in K562 and K562/A02 cells. FACS was used to determine the expression and function of glycoprotein (P-gp) on the cell membrane. Western blotting was used to determine the NF-κB p65protein in nueleus. Results There was a difference between K562 and K562/A02 cells growed in a halfadherent way rather than suspending ones, there were increases in the percentage number of cells at G0/G1 and S phases(P <0.05). This was mirrored by a decreasing number of cells within the G2/M phase(P<0.05). Butthere was no difference in apoptosis rate(P >0.05). mdr1 mRNA was detected in K562/A02 cells, in which the expression P-gp was much higher [(94.17±0.89)%:(1.41 ±O.491)%]. NF-κB p65 protein in nucleus was overexpressed in K562/A02 cells. Conclusion The activation of NF-κB signaling pathway may attribute to the formation of MDR in K562/A02 cells.

BACKGROUND:Preoperative walking ability and activities are good predictors of functional recovery of patients after hip replacement. But these objective assessment tools are invalid to predict postoperative function of patients with no preoperative walking ability.
OBJECTIVE:To assess the effect of preoperative subjective physical activity questionnaire to predict the 6-month postoperative physical functioning outcomes in elder patients receiving hip arthroplasty, and to determine which aspects of patient’s characteristics influence 6-month postoperative physical activity.
METHODS:A two-center prospective audit was carried out in elder patients who underwent hip arthroplasty between November 2010 and February 2013. These patients were divided into three groups, including the group of total hip arthroplasty for fractures of the femoral neck, the group of total hip arthroplasty for osteoarthritis and the group of hemiarthroplasty for fractures of the femoral neck. Al patients had fulfil ed Longitudinal Aging Study Amsterdam-Physical Activity Questionnaire (LAPAQ) and Short Form 36 (SF-36) recal ing their physical activity at 2 weeks before the fal accident (for fractures of the femoral neck) or admission (for hip osteoarthritis). Preoperative demographic data were also col ected. Postoperative assessment regarding subjective physical activity assessment including LAPAQ and SF-36, and objective physical activity assessment including timed up and go test and six-minute walk test were evaluated at the time of 6-month postoperation.
RESULTS AND CONCLUSION:Total y 115 patients finished the study. Both preoperative LAPAQ and SF-36 can play a predictor to probe 6-month postoperative function of objective and subjective activity in patients with femoral neck fractures or hip osteoarthritis undergoing hip arthroplasty. Preoperative LAPAQ seems better than preoperative SF-36 to predict postoperative physical activity. For hip fracture patients, because preoperative objective function cannot be assessed, preoperative LAPAQ can play an effective and subjective index to predict postoperative function of objective activity, and physical functions can recover 70%-80%at 6 months postoperatively. For hip osteoarthritis patients, postoperative physical function can be increased by approximately 27%compared with before hip arthroplasty. Patient’s characteristics also affect the postoperative physical activity, and the occurrence of preoperative complications is a most important factor.

OBJECTIVETo monitor human cytomegalovirus (HCMV) drug resistance in recipients of hematopoietic stem cell transplantation by phenotypic and genotypic methods.
METHODSHCMV clinical isolates was isolated from the urine of hematopoietic stem cell transplantation recipients treated with GCV. Tissue cell infection median dose (TCID50) of the isolates was calculated using Reed-Muench method, and their drug susceptibility was determined by plaque reduction assay. We amplified the UL97 DNA fragment of the virus by nested PCR followed by automated DNA sequencing.
RESULTSHCMV clinical strain isolated from the urine samples of the recipients using a human fibroblast cell line showed a TCID50 value of 10(-4.618)/0.1 ml and a 50% inhibitory concentration (IC50) to GCV of 5.847 µmol/L, suggesting its sensitivity to GCV. Alignment with the AD169 DNA reference sequence identified 4 point mutations of the virus at 1509 (T-C), 1575 (C-T), 1794 (T-C), and 1815 (C-G), and only the last mutation resulted in one amino acid mutation to D605E. No gene mutation was found in relation to GCV resistance.
CONCLUSIONSPhenotypic and genotypic assays were established to examine antiviral drug resistance of HCMV in recipients of hematopoietic stem cell transplantation. We did not find any drug resistance of the clinical HCMV isolate.

Objective:To compare the effect and safety of continuous veno-venous hemofiltration (CVVH)+double plasma molecular absorption (DPMA)+hemoperfusion (HP), CVVH+HP, and CVVH+plasma exchange (PE) in treatment of patient with severe wasp stings injury.Methods:Multicenter, historical cohort study and superiority test were used. From July 2020 to October 2022, patients with wasp sting injury and multiple organ damage admitted to the intensive care units (ICU) of five hospitals were consecutively screened and recruited into the CVVH+DPMA+HP group (intervention group). Propensity score matching was used to establish historical cohorts. Patients with severe wasp sting injury who hospitalized from January 2016 to June 2020 in each ICU were collected and matched 1∶1 with the intervention group, and divided into CVVH+HP group and CVVH+PE group according to their actual hemopurification protocols (historical control groups). The primary outcome was the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score on days 3 and 7 after initiation of treatment. Secondary outcomes included complications, length of ICU and hospital stays, and all-cause mortality. Multivariate Cox proportional risk regression was used to analyze the prognosis of patients.Results:After propensity score matching, 56 patients in intervention group and each of the two historical control groups were matched successfully. There were no significant differences in age, gender, comorbidities, biochemical test indices and critical illness scores among the groups. After treatment, APACHE Ⅱ score markedly declined in all groups, and the decrease was faster in the intervention group; treatment with DPMA [hazard ratio ( HR) = 1.04, 95% confidence interval (95% CI) was 1.02-1.08, P = 0.00], the decreased levels of body temperature ( HR = 1.02, 95% CI was 1.00-1.03, P = 0.02), serum creatine kinase (CK; HR = 0.98, 95% CI was 0.96-1.00, P = 0.05) and myoglobin (MYO; HR = 2.88, 95% CI was 1.24-6.69, P = 0.01) were independent risk factors for APACHE Ⅱ score decline to the target value (15 scores). There were no significant differences in the incidence of bleeding complications, filter or perfusion thrombosis, blood pressure reduction, catheter-related infection and anaphylaxis among the groups. Conclusion:CVVH+DPMA+HP regimen can significantly reduce the APACHE Ⅱ score of patients with severe wasp sting injury, and the efficacy is superior to CVVH+HP and CVVH+PE regimens, with safety.
