Objective:To observe the dynamic change of cystathionine β-synthase during cerebral ischemia-reperfusion and its effect in rats.Methods:The ischemic model was established with line embolism to block the middle cerebral artery .The reverse tran-scription-polymerase chain reaction ( RT-PCR) and Western blot assay were used to assess the expression of cystathionine β-synthase (CBS) in SHAM group,I group,and IR group.ELISA assay was performed to detected the homocysteine (HCY) level in plasma.After treating with the inhibitor of cystathionine β-synthase called hydroxyla mine(HA),the expression of hemeoxygenase 1(HO-1) and the pathologic change of the brain was evaluated .Results:As compared to sham group ,the expression of CBS was significantly up-regulated in ischemia-reperfusion group at 12 h post-reperfusion.Meanwhile,it existed the lowest level of HCY at 12 h post-reperfusion,comparing to sham grouzp ( 5.73 ±1.17 vs 2.88 ±0.93 , F=25.56 , P=0.001 ) .When inhibited the activity of CBS via using HA , the down-regulation of HO-1 protein and further damage in neuron were observed .Conclusion:Cystathionine β-synthase serves as an protective factor during cerebral ischemia-reperfusion.

OBJECTIVE To study the metallo-?-lactamases of 5 carbapenem resistant Pseudomonas aeruginosa isolates,which were recovered at 2006 in the Third People's Hospital of Yueqing. METHODS K-B method was used to determine the antimicrobial agents susceptibility in 5 isolates. The minimal inhibitive concentrations (MICs) of antimicrobial agents to these strains were determined by agar dilution method. Double disk synergy test was used to detect the metallo-?-lactamase. Molecular screening for blaIMP,blaVIM,and blaSPM was carried out using PCR method. The PCR product was sequenced. RESULTS One out of the 5 carbapenem resistant P. aeruginosa was positive for MBL double disk synergy test,and confirmed to contain blaVIM-2 gene. CONCLUSIONS A blaVIM-2-producing isolate of P. aeruginosa is identified. This carbapenem-resistant isolate is all multi-drug resistant.

36 rabbits were divided into control and experimental groups.In the experimen-tal group,the left renal artery was ligated or the left renal artery and vein wereligated simultaneously.All the animals were alive.After 3—8 months of the opera-tion,the rabbits were killed.The establishment of collateral circulation and theanatomical,histological and histochemical changes of the kidny were observed.The resultsobtained were as follows:1.Ligation of the left renal vessels causes atrophy of theleft kidney on account of the failure of collateral circulation establishment.Theright kidney of the experimental group showed obviously compensatory hypertrophy.The weight of the compensatory hypertrophied kidneys obviously increased.2.Thecompensatory hypertrophic growth of kidneys is due to the hypertrophy of existingn(?)phrons and the hyperplasia connective tissue.3.comparison of the controls,inthe JGI,PAS and AlP reactions with the compensatory hypertrophied kidneys,there were no striking differences.The results suggest that the compensatory hyper-trophied kidneys were normal at least on the renin secretion and reabsorption func-tion.

Objective:To investigate the prevalence and associated risk factors of pre-hypertension and hypertension in young and middle-aged population in Nanjing.Methods:Subjects of the study were those who underwent physical examination in the physical examination center of Nanjing Drum Tower Hospital from 2009 to 2016. The prevalence and risk factors of pre-hypertension and hypertension in young (aged 18-44 years old) and middle-aged people (aged 45-59 years old) were analyzed.Results:A total of 142 857 participants aged 18-59 years old were analyzed. Among them, 64 220 cases in the pre-hypertension group and 13 912 cases in the hypertension group. The prevalence of hypertension was 9.74% (12.51% in males and 5.82% in females). The prevalence of pre-hypertension was 44.95% (53.31% in males and 33.15% in females). In the middle-aged group, the prevalence of pre-hypertension and hypertension were 51.68% and 15.13%, respectively, which was higher than that in the young group (37.95% and 4.13%, respectively). The prevalence of pre-hypertension and hypertension in 2013-2016 was 45.37% and 10.65%, respectively, which was higher than that in 2009-2012(44.52% and 8.78%). In addition, the prevalence of abnormal blood glucose metabolism, abnormal blood lipid metabolism and abnormal glucose and lipid metabolism in the pre-hypertension group was higher than that in the normal blood pressure group, but lower than that in the hypertension group ( P<0.001). A logistic regression analysis indicated that age, overweight or obesity, hyperglycemia, hypertriglyceridemia and hypercholesterolemia were risk factors of pre-hypertension in male. Age, overweight or obesity, hyperglycemia, hypertriglyceridemia, hypercholesterolemia and hyper-low density cholesterolemia were associated with hypertension in male and with pre-hypertension and hypertension in female. Conclusions:Middle age, overweight/obesity, elevated fasting plasma glucose, elevated triglyceride and elevated total cholesterol were risk factors of pre-hypertension and hypertension in both men and women. Intervention on the related risk factors should be conducted as early as possible.

Objective Neuropsychiatric systemic lupus erythematosus ( SLE) is a common complication of SLE, whose path-ogenesis is not yet clear but associated with the alteration of cerebral blood flow ( CBF) in some studies.This study was to investigate the CBF alteration in SLE patients without overt neuropsychiatric symptoms by arterial spin labeling ( ASL) MRI. Methods Twenty-eight SLE patients without overt neuropsychiatric symptoms and 30 age-and sex-matched healthy controls underwent conventional MRI and ASL examinations, and all received such neuropsychologic tests as number connecting test-A ( NCT-A ) , digit symbol test ( DST ) , self-rating anxiety scale ( SAS ) , and self-rating depression scale ( SDS) .Independent sample-t test was used to detect the mean CBF in the whole brain, gray matter, and white matter of the SLE patients and healthy controls.The voxel-wise CBF maps of the two groups of subjects were further analyzed with the SPM8 software to compare the regional CBF between the two groups, followed by evaluation of the correlation between the regional CBF values and clinical markers. Results In comparison with the healthy controls, the SLE pa-tients showed significantly reduced CBF in the gray matter (40.5 ±3.7 vs 37.3 ±6.5, P=0.028) and the whole brain (38.0 ±3.5 vs 35.1 ±6.1, P=0.032), especially in the supplementary motor area and the adjacent middle cingulate, anterior cingulate, left medial frontal gyrus, left inferior frontal gyrus, and left insula (P<0.05, FWE corrected).The NCT-A score was negatively correlated with the CBF values of the left medial frontal gyrus (r=-0.402, P=0.032) and left inferior frontal gyrus (r=-0.382, P=0.045) of the SLE patients. Conclusion ASL and MRI showed significantly reduced cerebral blood flow in the SLE patient without overt neu-ropsychiatric manifestations, which was correlated with the change of the patient's cognitive function.

Objective Survey of Guangxi Traditional Chinese Medicine hospital hand hygiene facilities at all levels was made with improvement measures proposed.Methods Hand Hygiene Norms for Medical Workers questionnaires designed by the Ministry of Health was used in a field survey on hand hygiene facilities of 89 TCM hospitals in Guangxi.Results Facilities of the non-hand-touch taps,hand sanitizer and hand disinfectants were found satisfactory at key departments at all TCM hospitals in the region,yet poor performance with the hand drying facilities.Hospitals with such departments with non-hand-touch taps,hand sanitizer and hand disinfectants accounted for 93.3％,100.0％ and 100.0％.Only 41.6％ of the hospitals were found to use dry hand towels as drying facilities.Significant difference was found at various levels of hospitals' hand hygiene facilities.Conclusion The hand hygiene facilities at such hospitals in Guangxi are receiving growing attention,yet further investment is still required for further improvement and compliance of the medical staff in hand hygiene.

Objective To evaluate the left atrial(LA) and right atrial(RA) volumes and functions of fetuses in second and late trimester by using atrial volume tracking (AVT).Methods One hundred and seventy-six fetuses were enrolled in this study.Using AVT,the maximal and minimal volumes of RA and LA were measured from time-atrial volume tracking curves.RA and LA ejection fraction (RAEF and LAEF) derived from the value of atrial maximal volumes(LAVmax,RAVmax) subtracted atrial minimal volumes (LAVmin,RAVmin) and divided by LAVmax or RAVmax.Pearson correlation analysis was used to analyze the relationships between LAVmax,RAVmax,LAVmin,RAVmin,LAEF,RAEF and gestational ages.Results For all normal cases,the volumes of LA and RA were closely correlated with gestational weeks(r =0.80,0.85,0.83,0.82,P ＜0.001).The volume of LA was significantly smaller than that of RA (P ＜0.01).The RAEF and LAEF remained stable with advancing gestational age and there was no significantly difference between RAEF and LAEF (P ＞0.05).Conclusions This study establishes normal reference values for fetal RA and LA volumes during the second and third trimesters of pregnancy.The volumes of RA and LA are correlated with gestational weeks,and the volume of RA is bigger than that of LA.RAEF and LAEF are uncorrelated with gestational weeks,and there's no difference between RVEF and LAEF.

Objective To observe the anatomy status of the anterior clinoid process (ACP)and the anterior clinoid segment of in-ternal carotid artery (ICA)respectively by multisliced computed tomography (MSCT),and to provide useful imaging information for ACP removal surgery.Methods A total of 100 patients (200 sides)had volume rendering reconstruction of skull.Cranium was removed along cranio-orbital bone in simulation.Then the anatomical structures of the ACP and its surrounding were observed in cephalad direction.The total length,medium length,basic width,medium width of the ACP and the sagittal view curve length of anterior clinoid segment of the ICA from both sides were measured.Results Total length of left ACP was (9.82±2.48)mm,basal width was (9.47±1.88)mm,medium length was (5.03±1.55)mm,medium width was (6.1 9 ±1.75)mm;for right side total length was (10.41±2.1 6)mm,basal width was (9.66 ±2.21)mm,medium length was (5.86 ±2.48)mm,medium width was (6.66±1.5 1)mm.Left anterior clinoid segment of ICA curve length was (6.74±2.25)mm;right was (8.54±3.00)mm.Paired sample t test showed no significant difference in total length,basal width and medium width of ACP in both sides (P >0.05);while the difference in medium length and curve length of the anterior clinoid segment of ICA were statistically significant respectively (P <0.05).Conclusion MSCT can clearly display the vivisection and variation status of the ACP and the anterior clinoid segment of the ICA and can provide useful imaging information for removal of ACP in operation.

Objective　To investigate the role of bacterial DNA in systemic inflammatory response syndrome (SIRS). Methods　A total of 100 mice of Kunming species were divided into ten groups: E.coli DNA (30, 20, 10, 5 and 1 mg/kg ), 30 mg/kg of CT DNA, 60Co DNA, DNased DNA, organic residue of DNA extraction and sterile water control. The last two were pre-treated with D-galactoamine (600 mg/kg intra peritoneally). Animals were administratively injected via tail vein. General physical condition and the death rate of mice were observed within 48 h. Results　①Obvious lethal effect of double strand E.coli DNA on mice were observed with a dose-effect correlation, LD50=11.51 mg/kg. ②NO difference in death rate was found in the group of 30 mg/kg E.coli DNA with or without 60Co irradiation (10/10 and 8/10,P>0.05). ③No rats died in the group of DNased DNA, organic residue of DNA extraction and calf thymic DNA (0/10). Conclusion　Bacterial DNA may play an important role in the development of SIRS.
