A total of 192 poststroke patients with depression and anxiety were assigned randomly into study group (n =96) and control group (n =96).The study group received both capsules Shugan-jieyu and paroxetine while the control group paroxetine alone.Compared with the control group,scores of both Hamilton depression scale (HAMD) and Hamilton anxiety scale (HAMA) were significantly different at the end of week 2 and 6 in the study group (P ＜ 0.05).The HAMD and HAMA deduction rate and the scores of mangled extremity severity,mini-mental state examination and modified Barthel index at the end of week 6 of the study group were better than those of the control group (all P ＜ 0.05).The combined use of capsules Shugan-jieyu and paroxetine could improve symptoms of depression and anxiety,offer a higher safety and accelerate the rehabilitation of extremity function.

The epidemic characteristics and genotype of Bacillus anthracis strains in Liaoning Province ,China was analyze in this study .Six Bacillus anthracis strains from 2001 to 2011 were studied with multiple‐locus variable‐number tandem repeat analysis (MLVA) .BioNumerics4 .0 software was used to analyze the DNA fingerprint of statistics ,and cluster analysis results were obtained .Clustering analysis found that the 6 strains could be divided into two genotypes .For anthrax outbreaks ,the ge‐netic markers of multiple‐locus variable‐number tandem repeat were highly similar .It's suggested that MLVA is quite useful for investigation of strain relatedness in regions of outbreaks .

Objective To discuss the clinical values of transabdominal ultrasonic diagnosis of nontraumatic hiatal gastric hernia of esophagus in middle-aged and elderly people.Methods Thirty-two cases were examined with fasting and filing methods in half-sitting,standing,supine and supine right anterior oblique positions.The findings were contrasted with X-ray barium meal examination,endoscopy and operation.Results Twenty-nine cases were of sliding hiatal gastric hernia of esophagus,3 of impacted hernia.The ultrasonic diagnosis coincidence rate was 100%.The signs and symtoms of acoustic images were widening of esophageal hiatus diaphragmatic muscle(≥1.37 cm),echoes of gastric mucosa were found in superior phrenic hernail sac and inside hernial sac.The display rates were 100%,100%,15.6%respectively.Conclusions The transabdominal ultrasonic diagnosis of nontraumatic hiatal gastric hernia of esophagus in middle-aged and elderly people is brief and accurate.

ObjectiveTo evaluate the function of the salivary glands with gustatory stimulation by using MR DWI.MethodsA prospective study was conducted in 30 patients with nasopharyngeal carcinoma who had normal salivary function.A DWI sequence was performed on the salivary glands at resting state,and continually repeated on the parotid immediately after oral ascorbic acid stimulation over a period of 21 minutes (once every 18 seconds).The multiple b-values (0,400,600,800,1000 s/mm2) were used.ADC maps were evaluated with a manually placed region of interest including the entire salivary gland.The ADC of each gland was obtained by taking the mean of values on three contiguous sections containing the largest areas of the gland.The paired two-tailed Student t test was used to compare the ADC values of the parotid and the submandibular glands at rest,and of the parotid before and after stimulation.ResultsThe mean ADC value at rest was significantly lower in the parotid [ (1.23 ±0.12) × 10-3 mm2/s] than in the submandibular glands [(1.34 ± 0.07 ) × 10 -3 mm2/s,t =4.545,P ＜ 0.01 ].After acid stimulation,the ADC value increased from the baseline to (1.41 ±0.19) × 10-3 mm2/s firstly and then fluctuated at the following time,with a peak value of ( 1.49 ± 0.20 )× 10 -3 mm2/s and the average value of ( 1.36 ±0.17) × 10-3 mm2/s.The average value was significantly different from the baseline value (t =15.127,t =11.905,P ＜ 0.01 ).The minimum value [ ( 1.24 ± 0.14) × 10-3 mm2/s] was not significantly different compared to the baseline value (t =1.329,P ＞ 0.05 ).ConclusionMR DW1 can noninvasively evaluate the physiologic changes of salivary glands before and after acid stimulation.

OBJECTIVE To investigate the distribution and drug resistance status of extended-spectrum ?-lactamases producing(ESBLs) Klebsiella pneumoniae and to provide the basis for clinic anti-infective treatment.METHODS To use ATB-expression analyzer to identify the microbe.The drug susceptibility was tested with the K-B method and the ESBLs producing strains detected by diffusion confirmed test.RESULTS Among 137 strains of identified K.pneumoniae,34.3% of them(47 strains)produced ESBLs,and most had been shown in geriatrics ward.The drug resistance rate of ESBLs producing K.pneumoniae was higher than that in non-producing ESBLs one.So imipenem should be considered to be a preferred antibiotic when used on K.pneumoniae seriously infected cases.CONCLUSIONS The drug resistance of K.pneumoniae is a serious problem,we should pay attention on the status of ESBLs distribution,based on the susceptibility to choose the reasonable antibacterial to avoid the producing ESBLs bacteria spread out.

OBJECTIVE To investigate the drug resistance of ESBLs-producing Escherichia coli in community-acquired urinary tract infection for guiding the clinical drug-using.METHODS ATB-Expression analysis system was used for identification of bacteria,extra-susceptibility tests were detected by K-B method.RESULTS Totally 104 E.coli strains were detected,the isolation rate of ESBLs-producing E.coli was 13.5%,the resistant rates of E.coli were up to 70% to ampicillin,piperacillin and Co-trimoxazole,the resistant rate was up to 55% to ciprofloxacin and levofloxacin,and the susceptible rate was 100% to imipenem.CONCLUSIONS The E.coli is a main pathogen in community-acquired urinary tract infection,Its drug resistance is extremely severe.To enhance detecting drug resistance of pathogenic bacteria is of important significance for guiding the clinical rational drug-using and reducing drug-resistant strains.

OBJECTIVE To investigate the drug resistance of ESBLs-producing Escherichia coli and Klebsiella pneumoniae in local nosocomial infection,for guiding the clinical drug resistance. METHODS ATB analysis system was used for identification of bacteria,extra-susceptibility tests were detected by K-B method. RESULTS The isolation rate of ESBLs-producing E. coli and the K. pneumoniae was 29.9% and 30.8%,respectively. The drug susceptibility was indicated the resistance rate of ESBLs producing strains to antibacterial agents except imipenem was higher than that of non-ESBLs producing strains. CONCLUSIONS Detecting drug resistance of ESBLs producing strains is of important significance for guiding the clinical rational use of antibacterials and controling the epidemics.

Objective To evaluate the effects of hepatitis B virus on liver function,liver fibrosis,and liver pathological staging at different immune stages.Methods We made a retrospective analysis of 657 patients with chronic hepatitis B diagnosed in the First Hospital of Lanzhou University.Their liver function parameters,liver fibrosis parameters,and hepatitis B virus load were measured by automatic biochemical analyzer,automatic gammaradiation immunity analyzer,and quantitative PCR analyzer,respectively.Effects of hepatitis B virus on liver function,liver fibrosis in different immune stages were analyzed by variance analysis.Effects of hepatitis B virus on liver pathological staging at different immune stages were analyzed by linear trend chi square test analysis.Results In ALT normal chronic hepatitis B patients group,viral load had mild effects on liver function and liver fibrosis parameters.However,in ALT abnormal chronic hepatitis B patients group,viral load had a significant effect on liver function and liver fibrosis parameters,and the effect was most obvious in ALT＞double upper limit of normal group.The specific manifestation was that with viral load increasing,liver function parameters including ALT,AST,TBiL,DBiL,and IBiL increased,while TP and ALB decreased.Liver fibrosis parameters HA,LN,PcⅢ,and CIV all increased (P＜0.05).In ALT normal chronic hepatitis B patients group,viral load had no relationship with liver pathological staging.However,in ALT abnormal chronic hepatitis B patients group,especially ALT≥double upper limit of normal group,viral load was significantly related to liver pathological staging.Conclusion The effects of hepatitis B virus on patients' liver function at different immune stages were different,thus providing evidence-based medicine support for clinical antiviral treatment.
