Objective To analyze the distribution and antimicrobial resistance of pathogenic bacteria in urinary tract infection (UTI)so as to provide evidence for appropriate selection of antimicrobial agents in clinical practice. Methods From January 2001 to December 2008 in Shanghai Ruijin Hospital,4683 strains of pathogenic bacteria isolated from urine samples were detected by ATB system;drug susceptibility test was performed with disk diffusion method and pathogenic bacteria distribution and drug resistance was analyzed with WHO NET 5.3 software. Results Among 4683 strains of pathogenic bacteria,most was gramnegative bacilli,accounting for about 77.8%,of which predominant strain was Escherichia coli (68.7%,3217/4683).The predominant strain of gram-positive bacteria was Enterococcus faecalis,accounting for 10.0%(468/4683).Escherichia coli showed hish resistance rotes to ampicillin,piperacillin and compound snlfamethoxazole(SMZ-TMP),which were 76.6%,61.7%and 57.4%respectively,while a low resistance to imipenem,cefoperazone-sulbactam,piperacillin-tazobactam,Enterococcus faecalis showed high resistance rates to erythromycin,gentamicin and levofloxacin,which were 65.8%,43.2%and 31.1%respectively,and were most susceptive to vancomycin and teicoplanin, both with resistance rates of 0. The susceptibility rate of Enterobacteriaceae to imipenem was 100%. From 2006 to 2008, the detection rate of extend-spectrum β-lactamases ESBLs -producing Escherichia coil in outpatient increased year by year, from 28.7% to 43.3% (P<0.05), whereas no significant change was found in inpatients. The detection rate of (ESBLs)-producing Escherichia coil in inpatients was significantly higher than that in outpatients (P<0.05).The detection rate of ESBLs-producing Escherichia coil was 23.6%. The antimicrobial resistance rate in elderly patients was significantly higher than that in overall antimicrobial resistance rote (P<0.05). Conclusions The predominant bacteria of UTI are still gram-negative bacteria, main of which is Escherichia col. Bacteria are resistant to a variety of antibiotics. Approximate selection of antibiotics in clinical practice should be made on the basis of susceptibility test results.

Tumor 2008;28(1):40-43
Objective: To investigate the relationship between TFPI-2 gene expression and the invasion, metastasis, and prognosis of supraglottic carcinoma. Methods: Reverse transcriptase polymerase chain reaction and immunohistochemical methods were used to examine the expression of TFPI-2 in supraglottic carcinoma, and the relationship between TFPI-2 expression and the clinicopathological features of supraglottic carcinoma were analyzed. Results: Positive ratio of TFPI-2 expression was significantly increased at protein and mRNA levels in supraglottic carcinoma tissues (P < 0.05). TFPI-2 mRNA and protein expression were decreased with the increase in the invasive depth of supraglottic carcinoma (P < 0.05). TFPI-2 mRNA and protein expression were significantly lower in supraglottic carcinoma tissues with nodal metastasis and at III-IV clinical stage than those without nodal metastasis and at I - II clinical stage (P < 0.05). The staining intensity of TFPI-2 protein was also decreased with increase in invasive depth and nodal metastasis (P < 0.05). The supraglottic carcinoma patients with negative TFPI-2 protein expression had poor prognosis than those with positive TFPI-2 expression. Conclusion: The downregulation of TFPI-2 has a close relationship with invasion and metastasis of supraglottic carcinoma, and it may serve as a helpful marker in evaluating the metastasis and prognosis of supraglottic carcinoma.

Objective To investigate the effect of hyperacute intensive antihypertensive treatment on the prognosis of intracerebral hemorrhage in basal ganglia region. Methods From January 2013 to December 2015,100 patients with intracerebral hematoma in basal ganglia region (onset ≤3 h)at the Neurological Intensive Care Unit,the First Affiliated Hospital of Dalian Medical University were enrolled prospectively. They all randomly received the intensive antihypertensive or standard antihypertensive treatment voluntarily. They were divided into either an intensive antihypertensive group or a standard antihypertensive group according to the random number table (n = 50 in each group). Within 1 h after beginning to treatment,the target systolic blood pressure was controlled in 130 -140 mmHg in the intensive antihypertensive group,the target systolic blood pressure was controlled in 160 -180 mmHg in the standard antihypertensive group,and the target systolic blood pressure was maintained respectively in the following 7 d. Head CT was performed gain at 24 h after treatment. The intracranial hematoma expansion was evaluated. The National Institutes of Health Stroke Scale (NIHSS)and the modified Rankin scale (mRS)were used to
evaluate their prognoses. The differences of the cumulative mortality in both groups were compared at the same time. Results The incidences of hematoma expansion of the intensive antihypertensive group and the standard antihypertensive group were 12. 0% (6/ 50)and 30. 0% (15/ 50)respectively. There was significant difference between the 2 groups (χ2 = 4. 882,P = 0. 027). There were no significant differences in NIHSS scores within or between both groups at each time points (all P > 0. 05). They were followed up for 90 d,no adverse events occurred in both groups. The favorable prognosis rates of the neurological function were 36. 0% (18 / 50)and 18. 0% (9 / 50)respectively in the intensive antihypertensive group and the standard antihypertensive group. There was significant difference between the 2 groups (χ2 = 0. 411,P =0. 043). Kaplan-Meier curves showed that the cumulative mortality at 24 h,within 7 d and 90 d in the intensive antihypertensive group and the standard antihypertensive group were 4. 0% (2 / 50),6. 0%(3 / 50),and 10. 0% (5 / 50),respectively,those of the standard antihypertensive group were 10. 0%(5 / 50),24. 0%(12 / 50),and 30. 0%(15 / 50),respectively. The results of Log-rank test found that there was significant difference in cumulative mortality between the 2 groups (χ2 =6.280,P =0.012). Conclusions The intensive antihypertensive treatment in the hyperacute cerebral hemorrhage is safe and feasible in basal ganglia region. It contributes to improve prognosis of neurological function,and reduce the incidence of hematoma expansion and the 90 d cumulative mortality.

Objective To examine the independent effect of depression on activities of daily living of patients with mild cognitive impairment (MCI). Methods Data were obtained through the face-to-face interview. Totally 154 elderly patients that were screened from 552 old people by the Montreal Cognitive Assessment (MoCA) were diagnosed as MCI. They were investigated with the Geriatric Depression Scale, and instrumental ability of daily living (IADL) were measured by the Functional Activities Questionnaire. The effect of depression on IADL of patients with MCI was analyzed by logistic regression analysis. Results The prevalence of depressive symptoms among Chinese elders with MCI was 31.82%. The scores of Medical Outcomes Study Social Support Survey, and Functional Activity Questionnaire of depression group and non-depression group were significantly different (P<0.05) . Logistic regression analysis showed that scores of Functional Activity Questionnaire was positively associated with the scores of Memory Inventory for the Chinese (OR=1.36, 95% CI: 1.15-1.61) and depression (OR=6.19, 95% CI:2.07-18.55) . Conclusion The prevalence of depression in elderly patients with MCI was high. Depression would significantly reduce the IADL of the old patients with MCI. Medical workers should be aware of the extent and impact of depressive symptoms in MCI and take active measures in evaluating and treating the depressive symptoms.
8.Expression of mRNA for membrane-type 1, 2, and 3 matrix metalloproteinases in human laryngeal cancer.
Chinese Medical Sciences Journal 2004;19(3):170-173
OBJECTIVETo investigate correlation of expressions of membrane-type 1, 2, and 3 matrix metalloproteinases (MT1, MT2, and MT3-MMP) to the invasion and metastases in laryngeal cancer.
METHODSReverse transcription-polymerase chain reaction (RT-PCR) was used to examine the mRNA level of MT1, MT2, and MT3-MMP in 24 patients with laryngeal cancer. The relationships of these three MT-MMP expressions to clinicopathology were analyzed by statistics.
RESULTSThe expressions of MT1, MT2, and MT3-MMP were significantly higher in laryngeal cancer tissues than those in para-tumorous tissues (P < 0.01) and had a close relationship with invasive depth (P < 0.05). But no significantly different expressions of these three MT-MMPs were found in different primary location and different histological grade of laryngeal cancer (P > 0.05). The expression of MT1-MMP was obviously higher in patients with metastatic lymph nodes than that in patients without metastatic lymph nodes (P < 0.05).
CONCLUSIONMT1, MT2, and MT3-MMP play an important role in the progression of laryngeal cancer, and MT1-MMP may serve as a reliable marker in estimating invasive and metastatic potency of laryngeal cancer. Suppressing expressions of MT1, MT2, and MT3-MMP early may inhibit the invasion and metastases of laryngeal cancer.

Objective To investigate the prevalence and incidence of Keshan disease (KD) and the selenium concentration of food and hair in residents of Yongjin Village, Fuyu County, Heilongjiang Province, national monitoring site, in 2007. Methods According to the Standard of Keshan Disease Surveillance and the Standard of Diagnosis of Keshan Disease(GB 17021-1997), the residents living in the monitoring site were surveyed by clinical examination and electrocardiography. For individuals whose hearts showed abnormalities, a chest X-ray photograph was taken. The selenium concentrations of the residents' food (flour) and hair were assayed by flowing injection hydride generation atomic fluoremetric method(FI-HG-AFM). Results Nineteen KD patients were found from 282 residents in 2007 KD surveillance. The prevalence of KD, latent KD and chronic KD were 6.7%(19/282), 2.8%(8/282) and 3.9%(11/282), respectively. Five of the 8 latent KD cases were newly found. In addition, there were 5 the suspected KD cases, including 2 suspected chronic KD cases. No acute KD or sub-acute KD patients were found in Yongjin Village at this monitoring site this year. The average selenium concentration of children hair and residents food were (0.3197±0.0586)mg/kg and (0.0210±0.0062)mg/kg, respectively. Conclusions New cases of KD continued to emerge, indicating that etiological factors still exist. Therefore, the emphasis of monitoring KD in furore is founding the consummate report of infectious disease system and training the personnel to increase the reliability of monitoring.
