Objective To investigate the clinical distribution characteristics of persisters isolated from the chronic infected pa-tients,so as to provide scientific basis for effective clinical measures to prevent,control and treat persister-associated chronic infection.Methods Clinical microbial samples cultured from Jan.2013 to Dec.2014 were analysed by WHONET5.6.Four bacteria species with the highest isolation rate were performed for screening of chronic infection.Concentration of bacteria were detected by viable plate count method and then the growth curve were drew of each sample under the presence of anti-biotics.Persisters were comfirmed according to the specific growth curve under the presence of antibiotics.Results Four highest isolated bacteria species of the clinical samples were Escherichia coli (1 3.2%),Klebsiella pneumoniae (9.6%), Pseudomonasaeruginosa (8%)and Staphylococcusaureus (6.6%).862 chronic infection samples were generated out of 14 216 microbial samples and 41 persisters (4 strains of Escherichia coli,23 strains of Klebsiella pneumoniae,8 strains of Pseudomonasaeruginosa and 6 strains of Staphylococcusaureus)were isolated finally.Conclusion With such a comprehen-sively retrospective analysis of the hospital clinical microbial samples,can tell that the ratio of persisters in chronic infection was not high.And chronic infections are mostly caused by gene-mutated drug-resistant bacteria.However,the isolation rate of Klebsiella pneumoniae was relatively high,of which more attention should be payed to the prevention and control.

Objective: This experiment was designed to study the change of nitric oxide (NO) content in different parts of brain in rats suffering from iodine deficiency(ID) and hypothyroidism since their fetal period. Methods: Iodine deficiency animal model was made and NO content in hippocampus(HPC), cerebellum (CE) and cortex(CO) were measured by using NO test kit. Results: Urinary iodine and serum T 3?T 4 concentrations significantly decreased and learning-memory capacity was impaired in ID rats. NO content was significantly lower in HPC and CE in ID rats than in control rats.(HPC:11.61?2.31/2.3?1 18 ?mol/g Prot;CE:10.77?5.16/4.70?1.95 ?mol/g Prot).No difference was found in cortex. Conclusion: Iodine deficiency and hypothyroidism since fetal period could affect NO level in rat brain. Different parts of brain have different sensitivity to ID and hypothyroidism.The changes of NO content in hippocampus may contribute to the learning-memory impairment in ID rats.

Objective:To compare the therapeutic effects between immediate breast reconstruction (IBR) after skin-sparing mastecto-my and modified radical mastectomy (MRM) in young breast cancer patients (≤35 years), as well as to analyze the prognostic factors of IBR in these patients. Methods:The clinicopathological data of young breast cancer patients who had undergone IBR after skin-spar-ing mastectomy (60 cases) and MRM (68 cases) in Liuzhou People's Hospital from July 2008 to June 2014 were retrospectively ana-lyzed. Local recurrence, disease-free survival, and overall survival of the patients between the two groups were compared. The influ-encing factors for survival of the IBR group patients, such as age, tumor size, and nipple-areolar complex preservation, were analyzed. Results:All patients were followed-up for a period ranging from 15 to 88 months with a median of 51. In the IBR group, local recur-rence, distant metastasis, and death occurred in 3, 8, and 5 cases, respectively. The 3-and 5-year disease-free survival rates (DFSR) were 91.7%and 81.7%, respectively, whereas the overall survival rate (OSR) was 91.7%. In the MRM group, local recurrence, distant metastasis, and death occurred in 2, 9, and 5 cases, respectively. The 3-and 5-year DFSRs were 94.1%and 83.8%, respectively, where-as the OSR was 92.6%. No statistical difference was noted between the two groups (P>0.05). The analysis of prognostic correlation fac-tors in the IBR group patients shows that lymph node metastasis and estrogen and progesterone receptor-negative correlated with the tumor-free survival and overall survival rates (P<0.05). Conclusion:No apparent statistical difference in the comparison of the local re-currence and long-term survival rate was observed between the two groups' young breast cancer patients who underwent IBR after skin-sparing mastectomy and MRM. IBR after skin-sparing mastectomy is safe for young breast cancer patients with early-stage, and nipple-areolar complex preservation does not increase the risk of recurrence in the IBR group patients. Lymph node metastasis and es-trogen and progesterone receptor-negative are the major prognostic factors of IBR after skin-sparing mastectomy in young breast can-cer patients.

Objective:To explore therapeutic effect of noninvasive bilevel positive airway pressure ventilation (Bi- PAP)on aged patients with acute left heart failure (ALHF)and evaluation value of NT-proBNP for therapeutic effect in these patients.Methods:A total of 80 aged ALHF patients treated in our hospital were selected.According to random number table,they were equally divided into routine treatment group and BiPAP group (received BiPAP therapy based on routine treatment group ).NT-proBNP level,heart rate (HR),systolic blood pressure (SBP),di- astolic blood pressure (DBP),respiratory rate (RR)and arterial blood gas were compared between two groups be- fore and after treatment.Linear correlation analysis was used to evaluate the correlation among plasma NT-proBNP level and above indexes.Results:There were no significant difference in all indexes between two groups before treatment (P>0.05 all).Compared with before treatment,on 4h after treatment,there were significant reductions in levels of HR,SBP,DBP,RR and NT-proBNP,and significant rise in partial pressure of oxygen in artery (PaO2 ) in both groups (P<0.05 or<0.01),and compared with routine treatment group,there was significant rise in PaO2 [(75.13±19.93)mmHg vs.(85.88±18.47)mmHg],and significant reduction in NT-proBNP level [(3786.71± 1270.38)pg/ml vs.(2658.65±1222.08)pg/ml]in BiPAP group (P<0.05 both).Linear correlation analysis indi- cated that NT-proBNP level was significant positively correlated with HR (r=0.383),SBP (r=0.360),RR (r=0.345)and PaCO2 (r=0.413),and significant inversely correlated with PaO2 (r=-0.471),P<0.05 or<0.01. Conclusion:BiPAP ventilation therapy can improve clinical therapeutic effect in aged ALHF patients,and NT-proB- NP is help to evaluating its therapeutic effects.

Objective To observe the effect of serum containing Dahuang Zhechong Pills on vascular endothelial growth factor ( VEGF) expression in K562 cells of chronic myelogenous leukemia ( CML) and to develop new antiangiogenic drugs for CML treatment. Methods Enzyme-linked immunosorbent assay ( ELISA) was used for the detection of serum VEGF content in 38 CML patients, 11 acute myelogenous leukemia patients and 9 healthy volunteers. SD rats were used for the preparation of serum containing Dahuang Zhechong Pills, and then ELISA was applied for the detection of VEGF content in K562 cells pretreated with serum containing Dahuang Zhechong Pills. Results Compared with the healthy volunteers, myelogenous leukemia patients at chronic phase and acute phase had high serum VEGF content ( P<0.05 or P<0.01) . Compared with blank serum control group, the secretion of VEGF in K562 cells pretreated with serum containing Dahuang Zhechong Pills was decreased obviously ( P<0.01) , and VEGF expression decreased with the increase of drug concentration. Conclusion VEGF content is increased in myelogenous leukemia patients at chronic phase and acute phase, which may be related to the pathogenesis, progress and prognosis of chronic myelogenous leukemia. Serum containing Dahuang Zhechong Pills can inhibit the expression of VEGF in chronic myelogenous leukemia K562 cells and decrease VEGF protein expression in concentration-dependent manner.
