Male Wistar rats were randomized into 3 groups:The rats of group I received sham burning to serve as the control and those of groups and Ⅲ were inflicted with 20% and 30% TBSA third degree phosphorus burns respectively.No treatment was given to group Ⅱ.Group Ⅲwas further divided into 2:The rats of subgroup Ⅰ were debrided immediately and those of subgroup Ⅱ in the 6th hour postburn.The findings were as follows;(l)The tissue content of phosphorus was more significantly decreased in subgroup Ⅰ than in subgroup Ⅱ-(2)Twenty-eight rats of subgroup Ⅰ all survived while 9 of the 44 rats of subgroup Ⅱ died with a mortality rate of 20.5%.The mortality rate of group Ⅱ was 37.5%(3/8).(3)The recovery of serum electrolytes and other biochemical parameters occurred earlier in subgroup I.Our findings suggest that debridement as early as possible after phosphorus burns contributes significantly to the decrease of the victims mortality.

A fructosamine (DMF) method for the estimation of Serum glycosylated LDL (GLDL) is reported. The glycosylated rate of LDL (K value) is equal to GLDL/LDL. It is concluded that fructosamine method for the estimation of GLDL and K value is more convenient, fast, and has a high specificity, and is not interfered by glutathione, other reducing substances with low melecular weight, and the variation of serum proteins. GLDL and K value are thus suggested to be a better indicator for the diagnosis and evaluation of treatment in diabetes mellitus than the glycosylated serum total proteins.

Objective To investigate the inhibitory effects of Propionibacterium acnes (P.acnes) by 22 effective components of traditional Chinese medicines.

Results P.acnes was highly sensitive to both eugenol and cineole, and moderately sensitive to baicalin, emodin and others. The number of bacteria per oil field decreased obviously under microscopy and bacteriolysis was found after the treatment with those components. Conclusion Eugenol, cineole and other components of traditional Chinese medicines can inhibit P.acnes in vitro.

Objective To systematically assess the clinical efficacy and safety of apixaban versus enoxaparin in the prevention of venous thromboembolism (VTE) after major orthopedic surgery.Methods Based on the principles and methods of Cochrane systematic review,the Cochrane Library,PubMed,EMBASE,Chinese Bio-medicine Database,China Journal Full-text Database,VIP Database were searched from their establishment to March 2012 in whatever languages.Related journals were handsearched as well.Randomized controlled trials (RCTs) of comparing apixaban and enoxaparin in the prevention of venous thromboembolism after major orthopedic operation were included.Cochrane Collaboration' s tool was used for assessing risk of bias in the included trials.Cochrane Collaboration' s software RevMan 5.1 was used for statistical analysis.Results Four RCTs totaling 12 897 patients were included.Apixaban treatment showed significant differences in aspects of total VTE and all-cause mortality [relative risk (RR) =0.63,95％ CI(0.41,0.96)],major VTE [RR =0.59,95％ CI(0.19,0.98)] and symptomatic deep vein thrombosis (DVT) [RR =0.50,95％ CI(0.26,0.97)] when compared with enoxaparin,but the difference in fatal pulmonary embolism was insignificant[RR =1.57,95％ CI(0.41,5.99)].For patients undergoing total knee arthroplasty,apixaban was associated with significantly fewer major bleeding events[RR =0.55,95％ CI(0.32,0.96)] and fewer total bleeding events[RR =0.79,95％ CI(0.66,0.95)] than enoxaparin.For patients undergoing total hip replacement,however,the two treatments revealed no statistically significant differences.With regard to the incidence of drug-related serious adverse events,the two treatments displayed no significant difference[RR =0.97,95％ CI(0.59,1.58)].Conclusion Apixaban is effective in the prevention of VTE after major orthopedic surgery and can significantly reduce the risk of postoperative VTE.

To explore a sensitive , stable and handleable method for evaluating phagocytosis of mouse peritoneal macrophages by flow cytometry , and get a set of optimized solutions.Methods: The peritoneal macrophages obtained from ICR mice were divided into two part.One part was used directly ,and another part was 1∶1 diluted.Three fluorescent microsphere concentrations were used (5×106/well,1×107/well and 1.5×107/well).Incubation time were respective 1 h,1.5 h and 2 h.The adherent cells were digested by enzyme or cell scraper.The percentage of phagocytic cells ( PP) and the phagocytic index ( PI) were determined by flow cy-tometry.To verify and confirm the reliability of experiment conditions , effect of JKS on phagocytosis of mouse macrophages were evaluated with flow cytometric assays and chicken red blood-cell method.Results:The higher concentration of fluorescent microspheres meant PP and PI were higher.When cell concentration was 1×105-2×105 ml-1 ,incubation time was 1.5 h,concentration of fluorescent microspheres was 1.5 ×107/well,the PP and PI were the highest (89.87%,1.54).When incubation time was 2 h,the PP and PI declined(57.71%,1.51).Effect of cell concentration on the PP and PI were negatively correlated with fluorescent microspheres .After adherent macrophages were digested by trypsin+EDTA,the PP and PI were 44.51%,0.68.The PP and PI were 37.92%,0.57 after di-gestion by EDTA.The results were lower than using cell scraper.The PP(1 485 mg/kg group) of JKS were higher than control group that were evaluated with flow cytometric assays and chicken red blood-cell method.The difference was statistically significant ( P<0.05 ).Conclusion: These are the optimized solutions for the experiment such as the concentration of peritoneal macrophaes is (1-2)×105,the incubation time is 1 h and the concentration of fluorescent microspheres is 1×107/well.

Objective To explore the effects of Compound Antler capsule on the NO secretion of macrophages, cell cycle and[Ca2 +]i of mouse T lymphocytes.Methods ICR mice were randomly divided into 4 groups:experimental groups were respectively given Compound Antler capsule 233, 467, 1400 mg/kg via intragastric administration once a day and the control group were given the same volume of water for 30 days.NO concentration of mouse peritoneal macrophages was measured by Griess assay.The cell cycle distribution of activated mouse spleen lymphocytes was measured by flow cytometry.Fluorescent probe Fluo 4-AM was used to mark Ca2 + in lymphocytes, and the changes of its fluorescence intensity were observed with the multiscan spectrum.Results The result showed that NO concentration in experimental groups was higher than that in control group (P<0.01).More activated spleen lymphocytes of 467, 1400 mg/kg dose groups were entried into S and G2/M phase than control group (P<0.05).After activated by ConA for 8 min, the intracellular[Ca2 +]i in mouse spleen lymphocytes of 233, 1400 mg/kg dose group was higher than that of control group, respectively (P<0.05).After activated by LPS for 1, 4, 8 min, the[Ca2 +]iin mouse spleen lymphocytes of 233 mg/kg dose group was higher than that of control group, especially at 1 min(P<0.01).Conclusion Compound Antler capsule can improve NO secretion of macrophages and facilitate the entry of mouse spleen lymphocytes from the G0/G1 into the S phase.It also can increase the [ Ca2 +] i of activated lymphocytes to promote their proliferation.Thus Compound Antler capsule can improve the immune regulating ability.

Objective To search for application ways for the safe and effective clinical methods of arsenic-containing Compound Qinghuang Powder (Compound QHP) for the treatment of myelodysplastic syndrome (MDS). Methods Totally 200 patients with MDS were included in the study and treated with Compound QHP. After one-month treatment, the 60 patients with the blood arsenic concentrations <20 μg/L were randomly divided into control group and treatment group, with 30 cases in each group. Control group was given stable treatment, while the treatment group was given increased dose of realgar; blood arsenic concentration was detected monthly; realgar 0.1 g was increased each time until blood arsenic concentrations ≥20 μg/L and realgar ≤0.3 g/d. The blood arsenic concentration, clinical efficacy and safety in the two groups were observed. Results Totally 24 cases in each group were included for evaluation finally. The average blood arsenic concentration of treatment group was significantly higher than those of control group (P<0.05). The rate of hematologic improvement was significantly higher in treatment group (54.2％, 13/24) than that in control group (29.2％, 7/24) , with significant difference (P<0.05). The Hb, ANC, and PLT significantly increased in treatment group after treatment (P<0.05). There was no significant difference of incidence rate of adverse reaction observed between treatment group and control group (P>0.05). Conclusion In application of Compound QHP, the blood arsenic concentration can be monitored to adjust the daily dose of realgar, thus to increase the effective blood arsenic concentration, and then improving efficacy without increasing the clinical toxicity.

Objective To analyze the clinical efficacy and safety of compound Qinghuang powder (compound QHP) for treatment of myelodysplastic syndromes (MDS) and its association with blood arsenic concentration (BAC). Methods 40 patients with MDS were treated with compound QHP, and the clinical efficacy, safety, and its association with BAC were evaluated after treatment for 6, 9 months, respectively. Results After treatment for 6 months, the rate of hematology improvement was 32.5 % (13/40), and the effective rate was 87.5%(35/40). 21 cases depended on the blood transfusion before treatment, after treatment 6 cases completely got rid of blood transfusion and the blood transfusion of another 6 cases was decreased by more than 50 %. The absolute neutrophil count was increased from (0.50±0.13)×109/L to (0.93±0.33)×109/L (t= 4.130, P= 0.0008). The hemoglobin content was increased from (71.06±14.82) g/L to (80.41±27.35) g/L (t= 2.233, P= 0.0321). After treatment for 9 months, 76.2 % (16/40) of the patients got rid of blood transfusion or blood transfusion reduction was more than 50%. The platelet count was increased from (45.04 ± 24.38)×109/L to (60.65±29.46)×109/L (t= 2.241, P= 0.0335). The incidence of abdominal pain and diarrhea after treatment for 1, 3 and 6 months were 12.5 % (5/40), 10.0 % (4/40) and 5.0 % (2/40), respectively, all belonging to mild level . Before treatment , there were 12 patients with abnormal liver function , including 6 cases back to normal after treatment, and 6 cases of significantly relieved, without new case with abnormal liver function. Before treatment, there were 10 cases with abnormal myocardial enzymes, including 1 cases back to normal after treatment and 9 cases significantly relieved, without new case with abnormal myocardial enzymes. No patient with abnormal renal function was observed before and after treatment. The BAC was (7.71±5.65) μg/L before treatment, which was significantly lower than that of 1, 3 and 6 months [(29.27±9.07)μg/L, (27.79 ±10.18) μg/L and (31.98 ±12.55) μg/L respectively, all P< 0.0001]. There was no significant change of BAC among the patients after treatment for 1, 3 and 6 months (P> 0.05). The BAC in efficacy group [(33.48 ±12.56) μg/L] was significantly higher than that in non-efficacy group [(21.46 ±6.00) μg/L] (t=2.089, P=0.035). 12.5% (5/40) of the patients had mild gastrointestinal side effects after treatment for 1 month, while the BAC of them [(16.93 ±1.80) μg/L] was significantly lower than that in patients without gastrointestinal side effects [(31.78±1.39 ) μg/L, P<0.0001]. The occurrence rate of abdominal pain and diarrhea was decreased after treatment for 3 and 6 months, while the BAC was increased gradually. Conclusions Compound QHP is effective in the treatment of MDS with mild adverse reactions. There is no damage to the heart, liver, and renal function. Besides, it shows that reducing the gastrointestinal adverse reactions and maintaining the effective concentration of BAC play a significant role in the effect of compound QHP in the treatment of MDS.

Objective: To explore susceptibility genes for autism spectrum disorders (ASD). Methods: Whole-exome sequencing was carried out for 60 family trios affected with sporadic ASD. Genetic variants discovered in over 10% of the patients were selected for genotype-phenotype correlation and pathway enrichment analysis using Phenolyzer software and metascape database. Combining gene-phenotypic scores, pathway-related genes associated with neural and neurite triggering were screened for the candidates. Results: A total of 170 common variants were found to be associated with the ASD phenotype. Among these, there was only one high-confidence gene [SHANK2 (0.8146)] and four medium-confidence genes [ERBB2 (0.1322), LAMC3 (0.1117), PPFIA4 (0.1059), DISC1 (0.1002)]. Twenty-pathways and four biological processes were found to be statistically significant by pathway enrichment analysis, which included neuron projection morphogenesis (GO: 0048812), regulation of neuroblast proliferation (GO: 1902692), modulation of excitatory postsynaptic potential (GO: 0098815), and dendrite morphogenesis (GO: 0048813). Twenty-one genes were found to be closely associated with neurological and neurite triggering, among which only SHANK2, ERBB2, and DISC1 had above-medium confidence correlation scores with the ASD phenotypes. Conclusion Abnormal neuron projection morphogenesis (GO: 0048812) may be closely related to the occurrence of ASD. SHANK2, ERBB2, and DISC1 are susceptibility genes for ASD.

Objective To investigate the effect of pelvic floor stabilized structure preservation (PPSS) during robot-assisted laparoscopic radical prostatectomy (RARP)on postoperative continence recovery.Methods From October 2017 to April 2018,86 patients with prostatic cancer who underwent traditional RARP and RARP plus PPSS were included.There were 31 patients in non-PPSS group and 55 patients in PPSS group.In non-PPSS group,patients age was (68.48 ± 7.79) years old,BMI was (24.79 ± 3.05) kg/m2,median prostate volume was 63.54 (53.00-99.36) cm3,clinic T-stage T1-T2,T3,T4 accounted for 49.39％,22.58％,6.45％ and ISUP grade 1,2,3,4,5 accounted for 22.58％,22.81％,12.90％,12.90％,19.35％ respectively.In PPSS group,patients age was (69.53 ± 6.81)years old,BMI was (23.95 ± 3.03) kg/m2,median prostate volume was 73.39 (54.88-94.23) cm3,clinic T-stage T1-T2,T3,T4 accounted for 72.73％,7.27％,3.64％ and ISUP grade 1,2,3,4,5 accounted for 21.82％,18.18％,23.64％,18.18％,10.91％ respectively.The preoperative PSA,BMI,clinical T-stage,ISUP grade,and postoperative hospital days had no significant differences (P ＞ 0.05)between the two groups.Both groups were operated via transperitoneal approach.In the non PPSS group,endo-pelvic fascia and pubic prostate ligament was cut,and dorsal vessel complex was ligated.In PPSS group,the partial endo-pelvic fascia was bluntly pushed to the pelvic wall to preserve tendon arch,and pubic prostate ligament also was preserved without suturing and ligating dorsal vascular complex.The catheter was removed 7 d after RARP.The continence recovery were compared between the two groups,including pad number on the day of I,7,14,30,90 and ICI-Q-SF scores on the day of 30 and 90 after catheter removal.Results There was no significant difference in pad numbers used between the two groups on the day of 1,7,14,30 after catheter removal.On the 90th day,the proportions of using pad ≥4 in PPSS group were significantly lower than those in non-PPSS group (1.89％ vs.20.69％,P =0.004).No significant difference was found in ICI-Q-SF scores on the 30th and 90th day between the two groups.Univariate analysis showed that PPSS group used less pads than non-PPSS group on the 90th day [OR =0.07(95％ CI 0.01-0.65),P =0.019];T3 patients used more pads than T1-T2 patients [OR =9.19 (95％ CI 1.32-63.87),P =0.025].After adjusting for age,ISUP grading,T staging,and PSA,multivariate regression analysis showed that the risk of using pad ≥ 4 in PPSS group compared with non-PPSS group was 0.46,0.34,0.27,0.25,and 0.03 on the day of 1,7,14,30 and 90 after catheter removal,respectively.The PPSS approach didn't increase the risk of positive surgical margin.Conclusions Preservation of pelvic stabilized structure in RARP is very efficient in term of continence rate after RARP,and it does not increase the risk of positive surgical margin.
