OBJECTIVE To analyze the bacterial distribution and drug resistance in lower respiratory tract nosocomial infection(NI).METHODS To investigate 351 patients suffered from lower respiratory tract NI using the prospective monitoring methods,and doing the pathogenic bacterium cultivation for sputums of 351 patients and then taking the susceptibility test.RESULTS Totally 346 pathogenic bacteria were found in sputums of 351 patients.The major pathogenic bacteria were Pseudomonas aeruginosa,Escherichia coli,Klebsiella and Staphylococcus aureus.ESBLs were 36.0% and 40.0%,respectively in E.coli and Klebsiella,and MRSA were 82.1% in S.aureus.Drug resistances were common in Gram-negative bacilli(GNB) and Gram-positive cocci.Piperacillin/tazobactam and cefoperazone/sulbactam and imipenem were the most sensitive for GNB,S.aureus,S.epidermidis and Enterococcus were all sensitive to vancomycin.CONCLUSIONS Drug resistance of the pathogenic bacteria in lower respiratory tract NI is common,so it′s necessary to emphasize pathogenic bacterium monitoring and use the antibacterials exactly.

OBJECTIVE By investigating the incidence of nosocomial infection with objective monitoring method and prospective overall monitoring method, to analyze the advantage and significance between two methods. METHODS Using the objective monitoring method to study the incidence of nosocomial infection of patients after neurosurgical operation from May to December in 2003 and using the prospective overall monitoring method to study the incidence of nosocomial infection of patients after neurosurgical operation from May to December in 2002. All data were analyzed with Stata 7.0 soft. RESULTS There were 100 cases occurring nosocomial infection in 267 neurosurgical operation patients. The patient incidence of nosocomial infection was 37.5% and the rate of nosocomial infection cases was 50.9% with objective monitoring method, that was significant higher than those data coming from May to December in 2002 with 248 cases under prospective overall monitoring method, with which the patient incidence of nosocomial infection and the rate of nosocomial infection cases were 20.2%(50 cases ) and 21.4%(53 cases), respectively . Statistically significant difference was found (P

0.05).The average rate of three times NI prevalence surveys was 5.23% and that of NI prospective overall(monitoring) method in the same months was 6.60%,the statistical difference between them was found(P

OBJECTIVE To investigate the characteristics and risk factors of nosocomial infection(NI) in patients with hematological malignancies(HM),and provide the bases for making the controlling measures of NI.METHODS Using the targeted monitoring to study NI in patients with HM,and recording 14 factors such as the time of hospitalization,chemotherapy,count of leukocyte and absolute neutrophil count(ANC) and so on.The data were analyzed with unifactorial ?2 test and multifactorial Logistic-regression analysis.RESULTS Among 242 patients with HM the prevalence of NI was 35.5%(86/242) and the prevalence of NI time-cases was 52.9%(128/242).Among 86 patients of NI there were 27 patients occurred multiple sites NI(31.4%).The main infection sites were upper respiratory tract,gastrointestinal tract,lower respiratory tract,oral cavity and blood.66.7% Of NI happened in the period of chemotherapy and 7 days after chemotherapy.The time of hospitalization and ANC were independent risk factors of NI in patients with HM.CONCLUSIONS The patients with HM are susceptible population of NI,and NI often occurs in the period of chemotherapy and 7 days after chemotherapy.So medical staff should strengthen monitoring,and shorten the time of patient hospitalization and of recovery of ANC to reduce the prevalence of NI efficiently.

OBJECTIVE:To isolate and purify three principal degraded impurities of mitiglinide calcium (impurity A,B,C) and identify their structures,establish HPLC method for content determination of impurity A,B,C. METHODS:Mitiglinide calci-um was used as raw material and reacted with acid;3 impurities were then separated by HPLC and their structures were elucidated by IR,MS,1H NMR,13C NMR,LC-ESI-MS and ORD. 3 impurities of 3 batches of mitiglinide calcium were determined,and the determination was performed on Agilent Extend-C18 column with mobile phase consisted of 0.01 mol/L sodium acetate solution-ace-tonitrile-triethylamine(60:40:0.1,pH=3.0)at the flow rate of 1.0 ml/min. The detection wavelength was set at 210 nm and sam-ple size was 20 μl. The response tests of 3 impurities and mitiglinide calcium were conducted. RESULTS:After treated with acid, impurity A,B,C had been obtained,and their purity were 99.05%,98.87%,99.98%,respectively after isolation and purifica-tion;after identifying the structure, 3 impurities were S-2-bezylsuccinic acid, S-2-bezylsuccinic acid-4-methyl ester, methyl (2S)-2-benzyl-3-(cis-hexahydroisoindolin-2-ylcarbonyl) propionate;methodological study of content determination of impurities were all up to the requirement. The linear range of impurity A,B,C were 0.387 5-3.875,0.395-3.95 and 0.392 5-3.925 μg/ml(all r were 1.000 0). The response value of impurity A,B,C and mitiglinide calcium were 2.316 1,2.636 1,2.617 8 and 2.620 4,re-spectively. CONCLUSIONS:The structures of 3 principal degraded impurities of mitiglinide calcium have been identified and con-firmed;the content of them can be determined by HPLC main component self-comparison method.

Background: Dampness-heat syndrome is a major syndrome type in patients with a sharp deterioration of chronic renal failure (CRF). Qingshen Decoction, a compound traditional Chinese herbal medicine, could relieve the clinical symptoms of CRF patients, and was considered to have a certain reversal effect on rapid deterioration of renal function. Objective: To observe the changes of serum interleukin-8 (IL-8) and IL-18 levels in CRF patients with a sharp deterioration and dampness-heat syndrome, and to explore the curative efficacy of Qingshen Granule. Design, setting, participants and interventions: Sixty CRF patients with a sharp deterioration and dampness-heat syndrome from Department of Nephrology, the First Affiliated Hospital of Anhui College of Traditional Chinese Medicine, were randomly divided into treatment group (30 cases) and control group (30 cases), with another 20 healthy individuals as normal control. The patients in the treatment and control groups were all treated with Jiedu Xiezhuo II, a compound traditional Chinese herbal medicine, given as retention enema. Qingshen Granule was additionally administered to the patients in the treatment group with 1 dosage each time and 3 times a day. The treatment course was one month. Main outcome measures: The levels of serum IL-8 and IL-18 in the normal individuals and before and after treatment in the treatment and control groups were detected. Results: The total response rates of treatment group in clinical efficacy assessment and assessment of syndrome of traditional Chinese medicine (86.67% and 86.67%) were higher than those of the control group (56.67% and 60%), and there were significant differences between the two groups (P<0.05). The levels of serum IL-8 and IL-18 in CRF patients before treatment were obviously higher than those in the healthy individuals (P<0.01), and there were no differences in the levels of IL-8 and IL-18 before treatment between the treatment group and control group (P>0.05). After one-month treatment, the levels of serum IL-8 and IL-18 were markedly decreased in the two groups (P<0.01), and the levels of serum IL-8 and IL-18 in the treatment group were markedly lower than those in the control group (P<0.05). There were differences in decreased degrees of IL-8 and IL-18 levels between the two groups (P<0.05). Conclusion: CRF patients with a sharp deterioration and dampness-heat syndrome have high serum IL-8 and IL-18 levels. Qingshen Granule can reduce the levels of serum IL-8 and IL-18, and improve the renal function and ameliorate the clinical symptoms.

Objectives To evaluate the lung function in patients of severe secondary hyperparathyroidism caused by uremia and to analyze related factors.Methods The pulmonary function of 70 patients with uremia ( 40 patients with severe secondary hyperparathyroidism, 30 MHD patients without SHPT) and 30 healthy people was determined.Correlative analysis was performed between parameters such as pulmonary function indexes and clinical or laboratory parameters. Results Lung function was significantly different between patients with uremia and healthy subjects(P<0.05, respectively). A number of lung function indicators were negatively correlated with iPTH,C reactive protein( CRP) ,dialysis age but were positively correlated with hemoglobin (Hb) and albumin(Alb) (P <0.05).Conclusion Patients with SHPT show impaired lung function.IPTH, dialysis age, Hb, Alb and CRP can be used as important indicators of lung function.
