Objective To investigate the expression and activation of MMP-2, MMP-9 in cerebral tissues of cerebral ischemia-reperfusion rats and the effects of doxycycline on the cerebral edema. Methods Cerebral ischemia-reperfusion model was established by middle cerebral artery occlusion (MCAO). The rats were randomly divided into a sham-operated and 6 reperfusion groups according to different reperfusion periods (3 h, 6 h, 12 h, 24 h, 72 h, and 120 h groups). Dry weight method was used to evaluate hemispheric water content of the ischemic side after treatment with doxycycline. Western blotting analysis and Gelatin zymography were used to determine the expression and activity of MMP-2 and MMP-9 in the ischemic cerebral tissues. Results The protein expression and activity of MMP-2 were significantly increased in the ischemia tissue at 3 h and 120 h after reperfusion(P<0.01) ; the protein expression and activity of MMP-9 began to increase at 6 h after reperfusion (P<0. 01) , reached the peak at 24 h, and then returned to the basal levels at 120 h after reperfusion (P>0.05). The hemispheric water content of the ischemic side gradually increased with reperfusion periods compared with the sham-operated group. Dexycycline significantly reduced the hemispheric water contents compared with the normal saline at the same time points(P<0.05 or P<0.01). Conclusion MMP-2, MMP-9 can induce vasogenic brain edema by degrading basal membrane of capillary vessel. The alteration of MMP-2, MMP-9 expression and activities are likely associated with brain edema during cerebral ischemia-reperfusion.

Objective To determine the clinical features of Klebsiella pneumoniae pneumonia and antimicrobial resistance of Klebsiella pneumoniae, providing the basis for rational use of antibiotics. Methods Eighty-six strains of Klebsiella pneumoniae were isolated from the sputum specimen which collected from the inpatients in our hospital from Dec 2008 to Dec 2010,which were identified with Bio Merieum Vitek 2. A total of 86 children were enrolled in the study, which were divided into hospital infection/colonization group (n = 68) and community infection group (n = 18). Clinical information were recorded. Extended spectum β-lactamase (ESBLs) and antibiotic susceptibility of Klebsiella pneumoniae were determined. Results Klebsiella pneumoniae pneumonia in children mainly occured in infants, especially in infants with basic diseases.Clinical manifestations of Klebsiella pneumoniae pneumonia had no much difference from common pneumonia. The detection rate of ESBLs was high(76. 7%). ESBLs were found in 64 strains of the hospital infection/colonization group (94. 1% ,64/68) ,while in 2 strains of the community infection group (11. 1% ,2/18).There was a significant difference between the two groups (P ＜0. 01). The drug resistance of hospital infection/colonization group was significantly higher than that of community infection group. The strains of hospital infection/colonization group were sensitive with cefotan, piperacillin/tazobactam, carberpenem, amikacin and ciprofioxacin only, while were highly resistant to penicillins, cephalosporins and monoamine antibiotics.The average hospital stay of the hospital infection/colonization group was (15.0 ± 7. 1) d, while the other was (8. 2 ± 3. 8) d. There was a very significant difference between the two groups in average length of stay (P＜0.01). Conclusion Klebsieila pneumoniae pneumonia in children mainly occurs in infants with basic diseases. The symptoms are untypical. Klebsiella pneurmoniae multi-drug resistance is a serious problem,which must be paid attention to. We should make a difference between the two groups when antibiotics were prescribed.

Objective To investigate the association of the gene polymorphism of endothelial nitric-oxide synthase(eNOS) with pregnancy induced hypertension(PIH). Methods Sixty-six gravidas with PIH and 91 normal pregnant women(control) in the third trimester were investigated. The G894T mutation at exon 7 of the endothelial nitric-oxide synthase gene was studied by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results The frequencies of eNOS GG, GT and TT genotypes were 62.1%, 34.8% and 3.1% in PIH group and (79.1%,) 20.9% and 0.0% in control group, respectively (P0.05). Conclusions The variant (G-T) of 894 polymorphism site of eNOS is associated with the genesis of PIH, but not related to the severity of PIH. T allele may be a susceptible gene to PIH.

To observe the curative effect of treating small -incision cataract extraction by intraocular lens implantation combined with trabeculectomy for primary angle-closure glaucoma with cataract.
●METHODS: Totally 44 cases (52 eyes) of primary angle-closure glaucoma combined with cataract were selected to undergo the combined surgery, in order to observe the patients' pre - and postoperative eyesights, intraocular pressures and the postoperative complications.
●RESULTS: The postoperative eyesight was improved significantly as compared with the preoperative eyesight. The intraocular pressure was declined dramatically. The result was of statistical significance (P<0. 05). All the 52 cases' surgeries were performed by the same surgeon. The surgeries were processed smoothly, with 6 postoperative eyes of anterior chamber inflammation cell response, 3 eyes of anterior chamber fibrinoid exudate, 2 eyes of shallow anterior chamber through mydriasis and treatment with glucocorticoids and non - steroidal eyedrops before absorption, and no complications like malignant glaucoma, cyclodialysis, etc. were reported through mydriasis and pressure bandaging before recovery.
● CONCLUSlON: Treating the primary angle - closure glaucoma combined with cataract through the combined surgery has high reliability and desirable curative effect. The surgical method is simple to learn and applicable for promotion on the basic level.
