Objective:This paper makes analysis of problems of emergency equipment existing in clinical application and their causes and puts forward corresponding measure. Methods:Analysis of emergency medical equipment characteristic and the difference between conventional equipment. Find the first aid equipment management problems and reasons existing in the use, and risk assessment. Results:Hospital first aid equipment has the characteristics of more free time, emergency and risks, widely distributed in each department. By the personnel management, periodic inspection, cleaning and disinfection. Risk assessment shall be conducted by experts, the risk value high priority arrangement first aid equipment maintenance, to expect to minimize risk. Conclusion:First aid equipment management is a systematic and important work, to need department, maintenance personnel, equipment manufacturers and so on various aspects to cooperate with each other, to ensure the normal use of equipment.

OBJECTIVE To observe the clinical therapeutic effect of levofloxacin combined with cefoperazone-sulbactam on pulmonary infection caused by multidrug-resistant(MDR) bacillus infection.METHODS Eighty five patients with pulmonary infection caused by MDR bacillus infection were randomly divided into treatment group and control group,combined levofloxacin and cefoperazone-sulbactam were used in 45 patients of treatment group,ceftriaxone sodium was used in 40 patients of control group,their therapeutic effect was observed 7 days later.RESULTS Thirty four patients of treatment group were cured,7 patients with excellence,3 patients with improvement and only 1 patient was invalid.The total effective rate was 91%.Clinical manifestation such as cough,expectoration,and dyspnea had obviously improved.Sputum culture darkening rate was high.CONCLUSIONS Combined therapy of levofloxacin and cefoperazone-sulbactam has definite therapeutic effect on pulmonary infection caused by MDR bacillus infection.

AIM: To explore the main risk factors related to the incidence of endophthalmitis in patients after cataract surgery in China and to provide evidence for prevention.METHODS: The results of 5 studies on the main risk factors of endophthalmitis in patients after cataract surgery were analyzed by Meta-analysis method.
RESULTS: The pooled odds ratio values and 95% CI of age(≥70), diabetes, vitreous overflow, operative time ( ≥ 10min ), common operating room and control of using time of topical anesthetic were 1. 81(95% CI: 1. 43-1. 69),3. 66 (95% CI: 1. 64 - 8. 16),2. 21 (95% CI: 1. 46 -3. 32),3. 54 (95% CI: 2. 47 - 5. 06),2. 77 (95% CI: 2. 07 -3. 72),2. 09(95% CI: 1. 53-2. 86).
CONCLUSION: The main risk factors of endophthalmitis were the age(≥70), diabetes, vitreous overflow, operative time(≥10min), common operating room and control of using time of topical anesthetic.

Objective: To investigate the promoter region CpG island methylation status of glutathione S-transferase p1 (GSTP1) gene in prostate carcinoma (PCa) tissues and to search for new molecular markers for the early diagnosis of PCa. Methods: The promoter region CpG island methylation status of 31 PCa, 18 benign prostatic hyperplasia tissues (BPH) and 3 normal prostate tissues (NP) were examined by nest methylation-specific PCR (NMSP) technique, cloning and sequencing. Results: NMSP showed that the methylation rates of PCa, BPH and NP tissues were 83%, 0% and 0%, respectively. The CG sites methylation rates of PCa, BPH and NP tissues were 96%, 34% and 37%, respectively as determined by cloning and sequencing (P<0.01), with no significant difference found between those of BPH and NP tissues(P>0.05). A combination of NMSP and prostate-specific antigen (PSA) was better than PSA alone in screen of PCa. Conclusion: CpG islands of promoter region of GSTP1 gene is hypermethylated in PCa tissues. NMSP is sensitive and specific in detection of GSTP1 methylation, which may serve as a new method for early screen of prostate carcinoma.

Objective: To study the expression of hypoxia inducible factor (HIF)-1 alpha and vascular endothelial growth factor (VEGF) in papillary renal cell cancer (PRCC) and clear cell renal cell cancer (CC-RCC) and the correlation between each other. Methods: The expressions of HIF-1 alpha and VEGF in PRCC (n=13), CC-RCC tissues (n=20) and normal renal tissues (n=10) were detected by immunohistochemistry. The difference and correlation between each group were compared and analyzed. Results: The positive rates of HIF-1 alpha in PRCC, CC-RCC, and normal renal tissues were 38.46%, 85%, and 0%, respectively. There was significant difference between the three groups (P < 0.05). The positive rate of VEGF in PRCC, CC-RCC and normal renal tissues were 76.92%, 80%, and 10%, respectively. There was no significant difference between PRCC and CC-RCC. But the difference between renal cancer tissues and normal renal tissues was significant (P < 0.05). Expression of HIF-1alpha and VEGF had no correlation in PRCC tissues but had positive correlation in CC-RCC tissues. Conclusion: HIF-1 alpha is weakly expressed and VEGF is over-expressed in PRCC tissues. The expressions of HIF-1alpha and VEGF have no correlation. It suggests that the pattern of tumor angiogenesis in PRCC was different with CC-RCC.
