ABSTRACT
Objective:To preliminarily discuss the difference of ovary anti-miillerian hormone ( AMH) when cyclophosphamide is used in different time during menstrual cycle .Methods:Totally 30 young female patients with average age of (36 ±6.39) diagnosed as glomerular disease were treated with cyclophosphamide .According to the medication time , the patients were divided into follicular phase group and secretory phase group based on the property of menstrual cycle .Follicular phase group was treated with cyclophospha-mide during the first day and the eighth day of menstrual cycle .Secretory phase group was treated with cyclophosphamide after ovulato-ry time, namely the 14th day-the 16th day of menstrual cycle.AMH was detected before the drug treatment and 1st, 3rd, 6th and 10th cycles after cyclophosphamide treatment in the two groups .Results: AMH in the five periods had no statistic difference between the groups (P>0.05).There was significant difference in AMH before the treatment and after one-month treatment in the same group(P<0.05).AMH in different age groups showed statistic difference (P<0.05).Conclusion:There is no significant difference in AMH when cyclophosphamide is administrated in different time of menstrual cycle .However , ovarian function is impaired just by low dose cyclophosphamide (0.8g) with the first administration and will be recovered slowly at least half a year after the drug withdrawal .
ABSTRACT
Objective@#To evaluate the effects of application of vancomycin in the early stage of patients with extremely severe burn, in order to provide reference to drug for anti-infection treatment in the early stage of patients with extremely severe burn.@*Methods@#Data of 15 patients of Kunshan explosion on August 2nd, 2014, admitted to the Department of Intensive Care in our hospital were retrospectively analyzed. The clinical efficacy of continuously intravenous dripping of vancomycin (combined with imipenem) in the early stage of burns (before and on post burn day 14) was analyzed. (1) The steady state plasma concentration of vancomycin was monitored respectively 30 min before the third, sixth, and tenth medication with direct chemiluminescent imaging method. (2) The distribution of Gram-positive bacteria of patients during hospitalization and their drug resistance to 14 antibiotics commonly used in clinic were analyzed. (3) Serum level of procalcitonin (PCT), white blood cell count, percentage of neutrophils before and after treatment, and efficacy grade of anti-infection treatment in the early stage of burns were analyzed. (4) Serum levels of aspartate transaminase (AST), alanine aminotransferase (ALT), creatinine before and after treatment, and the adverse effects during medication were analyzed. The WHONET 5.5 statistical software was used to analyze the distribution of Gram-positive bacteria in all the pathogens, and the status of drug resistance of Gram-positive bacteria to 14 antibiotics. Data were processed with Wilcoxon rank sum test.@*Results@#(1) Twenty-nine times of steady state plasma concentration monitoring were performed in the patients in total, with the steady state plasma concentration of vancomycin from 4.3 to 42.1 μg/mL. In the monitoring before third, sixth, and tenth medication, the percentages of result reaching the standard were respectively 1, 3/14, and 2/7. (2) A total of 79 Gram-positive bacteria were isolated, including 49 (62.03%) strains of Staphylococcus aureus, 9 (11.39%) strains of Staphylococcus haemolyticus, 7 (8.86%) strains of Staphylococcus epidermidis, 12 (15.19%) strains of Enterococcus faecium, and 2 (2.53%) strains of Enterococcus faecalis. The above-mentioned Staphylococcus strains were with high drug resistance to antibiotics including penicillins, erythromycin, ciprofloxacin, and low drug resistance to linezolid, teicoplanin, and nitrofurantoin. The above-mentioned Enterococcus strains were with high drug resistance to antibiotics including erythromycin, ciprofloxacin, gentamicin, and low drug resistance to linezolid and teicoplanin. The above-mentioned Staphylococcus strains were all sensitive to vancomycin. Two strains of vancomycin-resistant Enterococcus were detected in the above-mentioned Enterococcus strains. (3) Serum level of PCT, white blood cell count, percentage of neutrophils of patients were (8.1±7.5) ng/mL, (24±10)×109/L, and 0.898±0.029 before treatment, which were significantly higher than (3.0±2.8) ng/mL, (12±5)×109/L, and 0.867±0.016 after treatment (with Z values respectively -2.103, -3.237, and -3.068, P<0.05 or P<0.01). After the early treatment, excellence, progess, and invalid results were achieved in 7, 5, and 3 patients, with the effective percentage of 4/5 in clinic. (4) There were no statistically significant differences in serum levels of AST, ALT, and creatinine of patients between before and after treatment (with Z values respectively-0.057, -1.508, and -1.363, P values above 0.05). Only one patient had liver and renal dysfunction during treatment.@*Conclusions@#The positive and reasonable use of vancomycin can remove most of the Gram-positive bacteria, and control the development of sepsis combined with imipenem in the early stage of patients with extremely severe burn. However, the dose of vancomycin should be individualized and the steady state plasma concentration should be monitored to maintain the blood concentration within the safe and effective range, so as to improve the rational use of vancomycin.
ABSTRACT
Objective To explore SIRT4 gene expression in tumor tissue and investigate the clinicol-pathological features in osteosarcoma .Methods In this study ,SIRT4 protein expression was detected in 106 os-teosarcoma tissues and 36 paired neighboring non -tumorous tissues by immunohistochemistry and determined the correlation between the SIRT 4 expression and the clinicopathological features .Results SIRT4 protein was dra-matically decreased in osteosarcoma cells compared with neighboring non -tumorous bone cells .The low expres-sion of SIRT4 was notably associated with a poor overall survival and disease -free survival in osteosarcoma pa-tients.By using univariate and multivariate analyses ,we confirmed that the increased SIRT 4 expression was an in-dependent factor in predicting better prognosis for patients .Conclu is on SIRT4 expression might be an inde-pendent biomarker for prognostic evaluation of osteosarcoma .
ABSTRACT
OBJECTIVE:To analyze the blood concentration monitoring data of 4 commonly used antiepileptic drugs(AEDs, sodium phenytoin,carbamazepine,sodium valproic acid,oxcarbazepine)in order to provide reference for rational use of drugs in the clinic. METHODS:415 patients underwent 4 AEDs blood concentration monitoring were selected from our hospital during 2014-2015,and the results of blood concentration monitoring were analyzed statistically. RESULTS:There were 680 cases of AE-Ds blood concentration monitoring in total. The main objects of serum concentration monitoring were young and middle-aged(range from 19 to 60),involving 449 cases in total(66.03%). 360 cases were in the normal range(52.94%). Among 361 patients receiving single drug therapy,the rates of serum concentration in the normal range were 80.77%for carbamazepine,which was higher than oth-er 3 AEDs(30.00% for sodium phenytoin,47.40% for sodium valproic acid and 40.38% for oxcarbazepine),with statistical signifi-cance(P<0.05). Among 54 patients receiving combination therapy,the serum concentration monitoring data of 67.65%patients treat-ed with double-combination therapy and 100%patients treated with triple-combination therapy deviated from normal range. CONCLU-SIONS:The rate of AEDs blood concentration reaching the normal range are in low level in our hospital. It’s necessary to strengthen medication education for patients to improve the compliance of patients;clinical efficacy of AEDs is evaluated on the basis of blood concentration monitoring and clinical symptom,and combination therapy should be avoided as much as possible.
ABSTRACT
<p><b>OBJECTIVE</b>To determine the immune repertoires of peripheral CD4+T cell receptor (TCR) Vb CDR3 in primary biliary cirrhosis (PBC) and analyze TCR diversity and preferred usage at sequence-level resolution.</p><p><b>METHODS</b>ARM-PCR and high-throughput sequencing were used to obtain millions of TCR Vb CDR3 sequences from peripheral CD4+T cells isolated from 7 patients with PBC and healthy volunteers. All sequencing data were analyzed, together with corresponding clinical information, by bioinformatic software. The Mann-Whitney U test was used for statistical analysis.</p><p><b>RESULTS</b>The PBC patients showed a lower level of diversity among the peripheral CD4+TCR Vb CDR3 than the healthy volunteers, and patients with higher level progression of the disease showed a greater lack of diversity. In addition, 4 specific preferred-usage amino acid sequences were discovered for the PBC patients: ASSFTGGPVEQY, ASSLISSGNNEQF, ATSRDTLAGGPGDTQY, and SASLEGNTEAF; these sequences were also found in higher frequencies in patients with later stages of PBC.</p><p><b>CONCLUSIONS</b>Decreased TCR Vb CDR3 diversities and specific preferred usage of TCR CDR3 sequences in peripheral CD4+T lymphocytes in PBC suggest that clonal expansion of a large number of CD4+T cells may be an important factor for PBC progression. These data provide a better understanding about the general characteristics of CD4+T cells in PBC patients and related to pathogenesis of the disease, and may provide useful insights into potential targets for immunotherapy.</p>

Methods 94 cases collected in the Department of Respiration, The Second Hospital Affiliated to Suzhou University from February 2011 to December 2012 were diagnosed as bronchiectasis, 34 cases in control group were given oral treatment for ambroxol 30 mg, three times one day, 60 cases in treatment group were added roxithromycin 75 mg on basis of control group, two times one day. Patients in two groups were both treated for 6 months. The therapeutic effect and the score of life quality and dyspnea scores in two groups were observed, and the changes of CT data were compared before and after treatment. Results After treatment, the life quality score and dyspnea score of two groups were all improved, but the treatment group was signiifcantly higher than the control group (P<0.05). The effective rate in treatment group was 86.67%, which was signiifcantly higher than 70.59%in the control group (P<0.05). After treatment, chest CT imaging score of patients in treatment group were improved, signiifcantly better than that in the control group (P<0.05). Conclusion Long-term low dose administration of roxithromycin can control and stable bronchiectasis symptoms, and improve signs and symptoms .
ABSTRACT
Objective To investigate the correlation between the expression of the activating and inhibitory receptors on periph-eral natural killer (NK) cells with the liver injury in the patients with hepatitis B virus related acute-on-chronic liver failure (HBV-ACLF) .Methods The peripheral blood samples were collected from 20 patients with HBV-ACLF and 20 patients with HBV-chro-nic hepatitis B(CHB) .The expressions of the activating receptors (NKP30 ,NKP46 ,NKG2D) and the inhibitory receptor (CD158a) on peripheral NK cells were detected by the multicolor flow cytometry .Results Compared with the HBV-CHB patients ,the ex-pression of the activating receptors NKP30 and NKP46 in the HBV-ACLF were remarkably unregulated(P<0 .05) ,but the expres-sion of the inhibitory receptor CD158a was markedly downregulated(P<0 .05) .Conclusion The enhanced expression of the activa-ting receptors NKP30 and NKP46 and the weakened expression of inhibitory receptor CD158a may be the important factor of the NK cells activation and the subsequent HBV-ACLF immune-mediated hepatocyte injury .
ABSTRACT
Objective To investigate the role of the chemokine receptor CXCR3 and its ligands in the migration of lymphocytes and acute hepatic failure. Methods BALB/cJ mice (6-8 weeks, female) were intraperitoneally injected with 100 PFU mouse hepatitis virus-3(MHV-3). The proportions and numbers of T cells and NK cells in liver, spleen, and blood as well as the expression of CXCR3 in T cells, and NK cells post MHV-3 infection was analyzed by flow cytometry. The hepatic mRNA level of the CXCR3-associated chemokines(CXCL9 and CXCL10) was detected by real-time PCR. A transwell migration assay was used to assess the chemotactic effect of MHV-3-infected hepatocytes and CXCL10 on the splenic lymphocytes. Results Following MHV-3 infection, the number of hepatic NK cells and T cells and the frequencies of hepatic NK cells and T cells expressing CXCR3 increased markedly; however, in the spleen and peripheral blood, they both decreased significantly. Moreover, the hepatic mRNAs levels of CXCL9 and CXCL10 were significantly elevated post infection. The transwell migration assay demonstrated that MHV-3-infected hepatocytes have the capacity to attract and recruit the splenic NK cells and T cells, and CXCL10 plays a key role in lymphocyte mobilization from the spleen. Conclusion Interactions between CXCR3 and its ligands (CXCL9 and CXCL10),especially CXCL10 may play a key role in the recruitment of intrahepatic lymphocytes and subsequent necroinflammation and acute hepatic failure in MHV-3 infection.
