OBJECTIVE To discuss the methods to control hospital infection in stroke unit and care strategies.METHODS Analyzing the causes and factors for hospital infection in stroke unit with prospective,objective and retrospective methods,we found control methods and improvements for clinical care.RESULTS The infection rate in test group was 9.13%(113 cases)and in control group was 14.60%(174 cases).The former was significantly lower than the letter(?2=17.44,P

OBJECTIVE To investigate the distribution and the drug resistance of pathogens in cerebral stroke patients with hospital infction and to provide a foundation for reasonabie application of antibacterials.METHODS Pathogenic bacteria were isolated from inpatients of burn department from 2003 to 2008,instruments assay or K-B disk diffusion method was taken to carry out the sensitive test.The drug resistance rate of the pathogenic bacteria was analyzed.RESULTS Totally 222 strains were isolated,among which 122 strains were Gram-negative bacteria,58 strains were Gram-positive ones,and 42 strains were fungi.The percentage of these three groups was 54.95%,26.13% and 18.92%,respectively.The main strains of Gram-negative bacteria were Pseudomonas aeruginosa,Escherichia coli,and Enterobacter cloacae,and that of the Gram-positive bacteria were Staphylococcus aureus,Enterococcus and S.epidermidis.The major strain of fungi was Candida albicans.The pathogenic bacteria tested showed high drug resistance.The detection rate of the meticillin-resistant S.aureus(MRSA)was 73.68%.The detection rate of the ESBLs from the K.pneumoniae and the E.coli was 60.00% and 33.33 %.CONCLUSIONS The pathogenic bacteria are multidrug-resistant.Inspecting pathogens and strengthening susceptibility tests are very important in reducing drug abuse,decreasing the resistance rate and raising the cure rate in hospital.

OBJECTIVE To establish the mechanism for monitoring,standardizing and alarming of relative risk factors to reflect the tendency of hospital infection.METHODS Data of hospital infection during six years were surveyed and analyzed completely.The prevalence baseline of hospital infection was chosen as the value to assess the control rate of hospital infection.The alarm value was set on the baseline.RESULTS The hospital infection revalence baseline and alarm value were used to assess the quality of infection control in whole hospital and each department objectively and accurately.These values could be also used to assess the effect of control of hospital infection among departments.They also could be used to survey the tendency of hospital infection and determine prevalence and outbreak of hospital infection.CONCLUSIONS Prevalence baseline and alarm value for hospital infection are valuable for preventing hospital infection and its outbreak.

Objective To investigate effects of complete resection of the cyst or incomplete resection with 3 ～ 5 mm remnant proximal cyst wall in treating adult type Ⅰ choledochal cyst (CC).Methods Medical records of 133 surgical patients with type Ⅰ CC from December 1995 to December 2017 in the First Affiliated Hospital of Zhengzhou University were reviewed retrospectively.According to whether to reserve the 3 ～ 5 mm cyst wall in proximal end of cyst,133 patients were divided into unreserved group (n =85) and reserved group (n=48),and the related indicators of the two groups were compared and analyzed.Results No significant difference was observed in age,sex ratio,clinical performance between the two groups(all P＞0.05).And there was no statistical difference in the operation time,intraoperative blood loss,and biliary-intestinal anastomosis diameter between the two groups(all P＞0.05).The main complications of the two groups were similar,including incision and abdominal infection,bile leakage,cholangitis,reflux cholangitis,bile duct stones and anastomotic stricture,and there was no statistical difference in the incidence of each complication.Biliary-intestinal anatomical site malignancy was observed in one patient with recurrent cholangitis in the reserved group in the 33th months.Conclusions There was no statistical difference in the incidence of early and late complications in two different methods of cyst management for treating adult type Ⅰ CC.Whether reserve the 3～5 mm cyst wall in proximal end of CC increases the risk of cancer still needs further studies.
