OBJECTIVE:To provide reference for the rational clinical prophylactic use of antibiotics. METHODS:The cases in whom the clinical prophylactic use of antibiotics between 2006 and 2007 in our hospital showed failure in efficacy were monitored to analyze the cause of failure,meanwhile the clinical samples were sent for culture,isolation,identification and drug susceptibility tests as well as drug resistance analysis. RESULTS:Cephalosporins,Quinolones,Penicillins,Cefhalosporins + enzyme inhibitor were more commonly used antibiotics in our hospital,with drug resistance rates at 57.21%,65.14%,68.63%,and 18.81% respectively. Among the total 240 cases monitored,the prophylactic use of antibiotics totaled 877 times,of which,388 (44.24%) were non-indicated drug use,459 (52.34%) showed drug resistance,286 (32.61%) involved improper drug choice,and 42 (17.50%) showed dual infection. CONCLUSION:The clinical prophylactic use of antibiotics in our hospital is far from perfect; therefore,it is urgent to tighten control on the standard prophylactic use of antibiotics.

Objective To investigate the relation ship between two polymorphisms within the CETP gene,TaqIB and I4O5V,and natural longevity in the Uygur population.Methods 191 healthy individuals over 90 years old and 53 control individuals who died before their 75 years were recruited.The polymorphisms within CETP gene,TaqIB and I4O5V,were genotyped by PCR-RFLP and PCR-Sequencing.Results There were no difference in the genotypes and alleles distribution of two polymorphisms within the CETP gene between longevity group and control group.Conclusions There was no correlation between the polymorphisms within CETP gene,TaqIB and I4O5V,and natural longevity of Uygur population in Hetian.

Objective To investigate the relationship between polymorphisms within the CETP gene, D442G,and natural longevity in the Uygur population. Methods 191 healthy individuals over 90 years old and 53 control individuals who died before their 75 years were recruited. The D442G polymorphism within CETP gene was genotyped by PCR-RFLP and PCR-Sequencing. Results There were no difference in the genotypes and alleles distribution of D442G polymorphisms within the CETP gene between longevity group and control group. Conclusions There were no the correlation between the D442G polymorphisms within CETP gene and natural longevity of Uygur population in Hetian. The difference of D442G polymorphism existed in not only races, but also regions where the same race dwelled.

ObjectiveTo investigate the effect of speech therapy on mental health of patients with aphasia. MethodsCRRCAE and SCL-90 were used to assess the speech and mental state in 28 aphasia patients. All aphasia patients were treated by using speech therapy and the changes before and after treatment were compared. ResultsThe scores in listening comprehension, repetition, naming, reading,reading comprehension, writing and counting were distinctly higher at post-treatment than that at pre-treatment. All SCL-90 factor's levels at post-treatment were distinctly reduced than that at preat post-treatment(P<0.01).Conclusions Speech therapy can improve the language function,as well as mitigate the mental symptoms.

Reflex tests are ordered when a particular test result indicates that additional testing should be performed according to the guidelines or the feedback process formulated by clinical consultation. The application scope of the reflex tests involves various subspecialties of laboratory medicine. The clinical application needs the support of qualified laboratory doctors, comprehensive information and financial system, clinical guidelines, and so on. Active application of reflex tests can promote the standardization of evidence-based medicine in clinical practice, save medical resources, and shorten the diagnosis and treatment time of patients.

ObjectiveTo study the effects of rehabilitation training on the expression of brain derived neurotrophic factor(BDNF) around the cerebral infarcted area of rats.Methods60 SD rats were randomly divided into rehabilitation group and immobilization group 24 hours after cerebral infarction.The rehabilitation group were given water maze training,rotating bar and rolling cage exercises everyday while the immobilization group were fixed in cages. Histochemistry was used to detect the BDNF expression around the cerebral infarcted area at the 1st,3rd,7th,10th and 14th day after infarction respectively.ResultsAt 1st day after the infarction, the expression of BDNF increased obviously around the infarcted area in both group. More BDNF positive neurons were found in the rehabilitation group than that in the immobilization group at 3rd day (P<0.01). BDNF positive astrocytes showed obvious increasing in both group. BDNF positive neurons decreased with time going, and the color became lighter at the same time .At the 7th day after infarction, there were only a few positive neurons, and seldom obvious positive neurons could be seen around the infarcted area at 10th and 14th day. Great deal of BDNF positive astrocytes were found at 3rd,7th,10th and 14th day, and the rehabilitation group showed more expression than that of the immobilization group(P<0.01).ConclusionsThe rehabilitation training may increase the expression of BDNF which might take an active part in the recovery of the central nervous system injury and the rebuilding of its function.

ObjectiveTo compare the outcomes of 3 modes of weaning,e.g.SmartCare (a computerdriven knowledge-based system),spontaneous breathing trials (SBBT) and empirical methods,used in patients with chronic obstructive pulmonary diseases (COPD) weaned off mechanical ventilation.MethodsSixty-eight COPD patients were enrolled and randomly (random number) assigned to receive SmartCare (SC group,n =24),SBT (SBT group,n=24) or empirical methods (EM group,n =20).The following data were recorded including beginning of weaning:time consumed for weaning,duration of mechanical ventilation,length of ICU stay,success rate of weaning,survival rate during hospitalization and the complications of mechanical ventilation.The patients were considered as successfully weaned when they were able to tolerate at least 48 consecutive hours of spontaneous breathing.ResultsTime required for weaning and total time for mechanical ventilation in SC group were greatly shorter than those in EM group (P =0.002,0.002),but there were no differences between SC group and SBT group (P =0.540,0.573).Though the length of ICU stay (7.5 d) in SBT group was notably shorter than that in EM group (82.5 d) (P=0.015),there was no difference between SBT group and SC group (8.0 d).Weaning success rate was greater in the SC group (88.3％) than that in EM group (50.0％),but there was no difference between SBT group (66.7％ ) and SC group.No significant differences in survival rate during hospitalization,rate of re-intubation,self-extubation and need for noninvasive ventilation were found among three groups.ConclusionsCompared to empirical methods for weaning,SmartCare could greatly increase the success rate of weaning,but it was not superior to SBT.

Objective To investigate the applicability of Cys C-based formulas for prediction of GFR in Chinese patients with CKD.Methods A total of 176 adult patients with CKD including 90 males and 86 females collected from 4 hospitals located in different geographic regions of China (Beijing,Shanghai,Dalian and Changsha) were enrolled in this study from September 2007 to July 2009.The rGFR was measured using 99mTc-DTPA clearance rate two-sample method.Cystantic C was measured by PETIA and PENIA respectively.The results of eGFR in the Larsson formula,Grubb formula,Hoek formula,Filler formula,Stevens formula and Hojs formula were compared with the rGFR to evaluate the calculation coherence,bias,precision,accuracy and the performance of correct phasing of the formulas.Results The mean 99mTc-DTPA clearance was [40.70 ( 19.09 - 86.49)] ml · min-1 · ( 1.73m2 ) -1.Significant difference was witnessed in the evaluation of GFR estimation formulas calculated by PETIA and PENIA (P ＜0.01).ICC and Spearman correlation analysis revealed a significant correlation between eGFR and rGFR.The ICCs of eGFR and rGFR ranged from 0.874 to 0.938.Compared with rGFR,the 30％ accuracy of all the eight evaluation formulas using PETIA and PENIA method were lower than 60％.The percentages of correct phasing in all the 5 stages of CKD were not ideal.With these formulas,percentages of correct phasing from CKD stage 2 to CKD stage 4 were lower than 65％.The eGFRs were underestimated by formulas evaluated by PENIA in CKD stage 1.All the eGFRs were overestimated remarkably by all equations in CKD stage 5.Conclusions None of the eight Cys C based formulas are ideal for estimation of GFR in Chinese CKD patients,and they can not be applied to Chinese patients directly.For this patient population,further studies will be needed to develop a more accurate Cys C-based GFR estimation formula that includes ethnicity,age and other factors.

Objective To summarize the clinical characteristics and diagnosis and treatment of hemangioma of small intestine in children.Methods Location,pathology,clinical manifestation,diagnosis and treatment of 3 cases from our hospital and 44 cases reported in our courtry with hemangioma of the small bowel were analyzed from 1994 to 2004.Results These tumors locating in jejunum,ileum,duodenum as well as parts small intestine were 31.9%,42.6%,4.2% and 21.3%,respectively.Solitary and multiple tumors were 29.8% and 70.2% separately.The histopatholical report of 10 cases revealed that capillary,cavernous,mixed type hemangioma and hematolymphangioma were 2,6,1 and 1 cases,respectively.Thirty nine children presented with recurrent black stool.Five patients manifest in the form of intussusception.One child passed a bloody stool so massive as to cause shock.Small-bowel obstruction occurred in 5 cases.The hemoglobin of 38 patients were lower than 90 g/L.The incidence of preoperative diagnosis was only 10.6%.All of patients were performed operation.Conclusions The frequent locations of hemangioma of small intestine are in ileum and jejunum,and multiple tumors are common.The diseases are characterized as recurrent hematochezia with painlessness.Preoperative diagnosis of a small bowel hemangioma can be very difficult.The segments of small bowel with hemangioma resection are the most method of the treatment.
