Objective To investigate the fluctuated pattern of endogenous bactericidal/permeability-increasing protein(BPI)levels,and to elucidate its significance in endotoxin response after major abdominal surgery.Methods Eleven patients undergoing major abdominal surgery were involved in present study.The levels of plasma BPI,lipopolysaccharide-binding protein(LBP)and interleukin-6(IL-6)were measured preoperatively and on postoperative days 1,3,5,7,and 14 by ELISA.Plasma endotoxin concentration was determined with the chromogenic limulus amebocyte lysate(LAL),which was modified by perchloric acid(PCA)pretreatment of samples.The polymorphonuclear neutrophil count was also done at each time point.Results In comparison with normal controls,plasma BPI/LBP ratios [(1.058?0.074)?10-3,P=0.004] were significantly increased on postoperative day 1,maintained at same level on day 3,and declined on day 5.No plasma IL-6 was detected from the blood of all the 11 patients prior to operation,but plasma IL-6 level rose rapidly on day 1 after operation(27.440?12.144pg/ml,P=0.04),maintaining a high level(11.530?5.312pg/ml)on postoperative day 3,and disappeared on day 5.Conclusions Plasma BPI/LBP ratios were markedly elevated during 3 days after a major abdominal surgery,and endogenous elevated BPI may play an important role in prevention from the development of endotoxemia in surgical patients.

The purpose of this study was to investigate the effect of high mobility group 1 protein (HMG 1) on TNF ? expression as well as release in the kidney, and their potential role in the pathogenesis of acute renal injury associated with sepsis. Using a sepsis model by cecal ligation puncture (CLP), 50 male Wistar rats were randomly divided into normal control group ( n =10), CLP group ( n =20), and sodium butyrate treatment group ( n =20). At serial time points animals in each group were sacrificed, and blood as well as kidney tissue samples were harvested to determine HMG 1/TNF ? mRNA expression, tissue TNF ? protein level, and serum creatinine content. Compared to normal controls, both HMG 1 and TNF ? mRNA levels significantly increased in the kidney during 12～24h after CLP ( P

ObjectiveTo investigate the relationship between sepsis induced high mobility group 1 (HMG 1) gene expression and endotoxemia in rats. MethodsSepsis was induced by cecal ligation puncture (CLP). One hundred Wistar model rats were randomly divided into four groups: normal control group ( n =10), sham operation (SO) group ( n =10), CLP group (further subdivided into 2?h, 6?h, 12?h, 24?h, 48?h and 72?h post CLP, n =10 in each subgroup), and bactericidal/permeability increasing protein(rBPI 21 ) treatment group (further subdivided into 12?h, 24?h post CLP, n =10 in each subgroup). Tissue samples from the liver, lungs and kidneys were harvested for the measurement of endotoxin concentrations and HMG 1 mRNA expression by RT PCR. Results Compared to normal control and SO groups the HMG 1 mRNA levels significantly increased in tissues during 6～72?h post CLP ( P

Objective To evaluate systematically the clinical efficacy of surgery combined with anti-TNFalpha in treatment of Crohn's disease (CD) with perianal fistula.Method Database including China Biology Medicine disc,Wan Fang Database,PubMed,Cochrane Library and EMBASE were searched withCrohn's disease,anal fistula,fistula,perianal fistula,surgical procedure,surgery,surgical,anti-tumor necrosis factoralpha,anti-TNF-alpha,TNF-alpha,克罗恩病,Crohn's病,肛瘘,手术治疗,外科手术,抗肿瘤坏死因子α制剂,肿瘤坏死因子,肿瘤坏死因子配体超家族员2”between the database establishment and June 2016.Literatures of retrospective case-control studies about surgery combined with anti-TNF-alpha therapy and single surgery in treatment of CD with perianal fistula were retrieved.Data were extracted and evaluated by 2 independent researchers.Patients who underwent surgery combined with anti-TNF-alpha therapy were allocated into the combined therapy group and patients who underwent single surgical treatment were allocated into the surgery group.The complete healing rate,partial healing rate and recurrence rate after therapy were compared between the 2 groups.Count data were represented as the odds ratio (OR) and 95％ confidence interval (CI).The heterogeneity was analyzed by theI2 test.Result Six retrospective case-control studies were retrieved and total sample size was 598 patients,including 256 in the combined therapy group and 342 in the surgery group.The result of Meta analysis showed that there was no significant difference in postoperative complete healing rate and partial healing rate between the 2 groups (OR =1.36,1.47,95 ％ CI:0.94-1.97,0.56-3.88,P ＞ 0.05),and recurrence rate after therapy in the combined therapy group was significantly lower than that in the surgery group (OR =0.26,95％ CI:0.16-0.44,P ＜ 0.05).Conclusion The complete healing rate and partial healing rate of patients with CD with perianal fistula undergoing surgery combined with anti-TNF-alpha therapy are not superior to that undergoing single surgical treatment,however,recurrence rate after therapy is lower for patients undergoing surgery combined with anti-TNF-alpha therapy.

Objective To observe the effect of small interfering RNA(siRNA) targeting Survivin gene on survivin expression,proliferation and apoptosis of hepatocellular carcinoma cell line MHCC-97H.Methods Survivin sequence specific siRNA was designed and synthesized.siRNA/liposome complex was transfected into hepatocellular carcinoma cell line MHCC-97H.The MHCC-97H cells were divided into Survivin siRNA group(Si-survivin),negative control siRNA group(NC group)and blank group (normal control group).Survivin mRNA and protein expressions were detected by reverse transcription-PCR and Western blot,respectively.The proliferation of MHCC-97H was measured by methythiazolydiphenyl-tetrazolium bromide assay.The Annexin V/PI double labeled flow cytometry was employed to measure the apoptosis at 24 h after transfection in different concentrations of Survivin siRNA(12.5,25.0 and 50.0 nmoL/L,respectively).Results After 48 h of transfection,the Survivin mRNA levels were 0.55 ± 0.16 (Si-survivin group),0.85 ± 0.28 (NC group) and 0.93 ± 0.40 (normal control group),respectively,which were significantly different among 3 groups (F =414,P ＜ 0.01).The level of Survivin mRNA was the lowest in Si-survivin group,which was statistically different with NC group and normal control group (t =-20.56,-28.37,all P ＜ 0.001).The levels of Survivin protein expression in 3 groups were 0.602 ± 0.005 (Si-survivin group),0.835 ± 0.007 (NC group) and 0.993 ± 0.003 (normal control group) at 48 h after transfection,which were statistically different among 3 groups (F =238,P ＜0.01).The lowest level of protein expression was in Si-survivin group,which was statistically different with NC group and normal control group (t =-40.17,-66.03,all P ＜ 0.001).After 72 h and 96 h of transfection,the inhibitory rate of cell growth was significantly higher in Si-survivin group [(19.5 ± 3.6)％,(12.0 ± 0.9)％] compared with that in NC group [(3.6 ± 0.9) ％,(-1.3 ± 6.1) ％] (t--36.18,42.53,all P ＜ 0.05).The apoptosis rates in 12.5,25.0,50.0 nmol/L Survivin siRNA were (22.64 ± 2.54) ％,(35.37 ± 3.28) ％ and (53.28 ± 4.35) ％,respectively.However,in NC group and normal control group,the apoptosis rates were (8.77 ± 1.25) ％ and (9.72 ± 1.37) ％.The rates were statistically different among those 5 groups(F =35.93,P ＜0.01).And in the apoptosis rates of siRNA groups in different concentratiom were statistically different when compared between each two groups (t =-29.73,-38.57,all P ＜ 0.001).Conclusion Survivin specific siRNA can inhibit the proliferation and induce the apoptosis by blocking Survivin gene expression in hepatocellular carcinoma cell line MHCC-97H.

Objective:To explore the characteristics, diagnosis, and treatment of precursor B-cell acute lymphocytic leukemia with C- MYC rearrangement (preBLL) in children. Methods:The clinical data in 2 cases of childhood preBLL in Department of Hematology, Children′s Hospital Affiliated to Capital Institute of Pediatrics in June and August 2019 were summarized and analyzed.Results:Both cases were acute lymphoblastic leukemia with precursor B-cell immunophenotype.Hepatosplenomegaly and peripheral white blood cells were significantly increased, and the morphology of bone marrow was L3. C- MYC rearrangement was discovered by cytogenetic tests.Both children have received the treatment of the mature B-cell tumor protocol (FAB/LMB96), and early remission was developed in 1 case with TP53 gene mutation but relapsed thereafter and died finally.Another case had reached sustained complete remission after treatment. Conclusions:Children with preBLL is rare, and routine C- MYC rearrangement should be performed in children with Precursor B-cell lymphoblastic leukemia whose morphology of bone marrow was L3.Its treatment needs to be further studied, and multi-center clinical trials need to be actively conducted to analyze and summarize large numbers of cases to identify effective protocol and improve the prognosis.

Objective Pemetrexed and β-elemene can inhibit the growth of tumor cells .This study was to investigate the effect of pemetrexed combined with β-elemene on the proliferation and apoptosis of cervical cancer HeLa cells. Methods Cervical cancer HeLa cells were treated with pemetrexed at the concentrations of 38, 76, 152, 228, and 304μg/mL, and at 24 and 48 hours of treatment subjected to MTT for detection of their proliferation .The experiment included four groups , with the cells treated with β-elemene ( 125μg/mL) , pemetrexed ( 76 μg/mL ) , β-elemene ( 125 μg/mL ) +pemetrexed (76μg/mL), and nothing (blank control) for 24 hours, followed by determination of their proliferation and apoptosis by MTT and flow cytometry, respectively. Results Pemetrexed at 38, 76, 152 and 228μg/mL inhibited the proliferation of the HeLa cells in a concentration-dependent manner, with the inhibition rates of (7.24 ±3.78), (7.94 ±4.37), (11.10 ±2.86) and (15.88 ± 3.38)%at 24 hours, and (16.69 ±0.95), (22.54 ±1.53), (24.48 ±0.92) and (25.54 ±3.61)%at 48 hours, both with statis-tically significant differences between any two groups (P<0.05).Significant differences were also found in the proliferation rate of the same concentration of pemetrexed at the two time points (P<0.05).The combination of pemetrexed and β-elemene showed an inhibi-tion rate of (49.95 ±5.76)%at 24 hours, remarkably higher than (24.36 ±5.59)%in theβ-elemene group and (10.69 ±1.37)%in the pemetrexed group (P<0.01). Conclusion Pemetrexed combined with β-elemene can significantly inhibit the proliferation and synergistically accelerate the apoptosis of HeLa cells .

Objective To investigate the underlying mechanism of Huayu Xiaozheng granule(HYXZ)in the treatment of ectopic pregnancy(EP).Methods The potential ingredients and targets of HYXZ were identified and screened.PPI network,GO enrichment and KEGG pathway analysis were established to understand the potential and intricate mechanism of HYXZ in treating EP.The effects of HYXZ on HTR-8/SVneo cells migration and invasion were detected by wounding healing assay and transwell migration assay respectively,as well as the influence of HYXZ granule on JAK/STAT pathway and associated proteins were assessed by western blot under the control of JAK/STAT pathway inhibitor and agonist.Results A total of 375 active ingredients,45 known targets and 207 predicted targets of HYXZ were obtained.A PPI network has constructed to know the relationship of 252 common targets of drug targets and disease targets,from which we screened out 15 key targets:STAT3,MMP9,TLR4,HIF1A and others.Scratch test showed that HYXZ inhibited the migration of the HTR-8/SVneo cells cells in a time and dose-dependent manner;Transwell test showed that the number of transmembrane cells decreased significantly(P<0.05)after 48 h with various concentrations of HYXZ;Western blot experiment showed that the expression of JAK/STAT pathway protein decreased significantly(P<0.05);and the expression of its related proteins uPA,HIF1and N-cadherin were inhibited(P<0.05),the tendency of which was consistent with the inhibitor AG490,but opposite to the agonist IL-6.Conclusion HYXZ inhibited JAK/STAT pathway,and associated proteins uPA,HIF1A and N-cadherin,thereby suppressing the mobility and invasiveness of the HTR-8/SVneo cells,which is conductive to clarify the mechanism of HYXZ in the treatment of early EP.

Patients with radioactive enteritis generally have certain intestinal microecological imbalance. Traditional Chinese Medicine (TCM) has showed good advantage in regulating intestinal microbial flora. In clinical practice, patients are treated based on syndrome differentiation of heat toxin damaging collaterals, cold-heat mixed syndrome, spleen deficiency and dampness stagnation, spleen and kidney yang deficiency, yin deficiency and body fluid deficiency. The Baitouweng Decoction, Wumei Pill, Sijunzi Decoction are the common prescriptions. TCM can promote the balance of intestinal microecology and treat digestive diseases such as radioactive enteritis, by improving the abundance of intestinal flora, inhibiting the level of inflammatory cytokines, and playing the role of probiotics and immune regulation.
