Objective To explore the abdomen surgical incision infection risk factors,and to put forward prevention countermeasures.Methods 1 854 patients with abdominal surgery were selected as subjects.According to whether had surgical incision infection,they were divided into the infection group(76 cases)and the non -infection group(1 778 cases).Single factor analysis and Pearson correlation analysis were used to summarize abdominal surgical incision infection risk factors.Results Single factor analysis results showed that age,BMI,category of incision,operation timing,operation time,diabetes mellitus,drainage tube placement,summer were risk factors for abdominal surgery incision infection (t or χ2 =8.925,5.840,5.376,5.445,5.846,19.674,5.846,19.674,all P <0.05).Pearson correlation analysis showed that age,BMI,category of incision,operation timing,operation time,diabetes mellitus, drainage tube placement and summer surgery were risk factors for abdominal surgery incision infection (r =0.746, 0.689,0.746,0.689,0.691,0.548,0.760,0.548,all P <0.05).Conclusion Abdominal surgery incision infection is associated with many factors.It is necessary for all kinds of risk factors for targeted intervention to reduce incision infection rate.

A Review Many studies indicate that apoptosis is involved in the progression of congestive heart failure. At present, mechanisms that mitochondria regulates cell apoptosis is widely accepted.Cardiac myocytes have abundant mitochondria,which plays an important role in maintenance of cell physiological function. Recent studies find that cardiac energy metabolic shifts occur as a normal response to diverse physiologic and dietary conditions and as a component of the pathophysiologic processes which accompany cardiac hypertrophy, heart failure, and myocardial ischemia.Both clinical and experimental studies show that cardiac function can be improved and apoptosis is inhibited by intervention in energetic metabolism of myocytes.

Objective To study the effect of caveolin-1 on renal injury and the expression of tight junction proteins in MRL/lpr mice kidney.Methods The mice were divided into 4 groups:5 mice in the normal control group (BALB/c mice);the MRL/lpr lupus mice (n=18) were randomly divided into the MRL/lpr group in which 6 mice were included;the negative control group in which 6 mice were included;the caveolin1 transfection group in which 6 mice were included.The changes of urine protein,the levels of urea (BUN) and creatinine (Cr) were detected.The expressions of claudin-5,occludin,ZO-1 and caveolin-1 protein were determined by western bloting.Analysis of variance was used to determine statistical significant differences between the two groups.A significance level of 0.05 was considered as signigicant.Results Compared with the control group,24 h urine protein [(2 894±437) mg,(412±72) mg],BUN [(8.7±1.5) mmol/L,(6.9±0.4) mmol/L],Cr [(106±22) μmol/L,(85±4) μmol/L] were significantly increased,level of caveolin-1 protein increased (265±17,61±6),the level of occludin (114±12,190±12),claudin-5 (60±5,80±6) and ZO-1 (98±11,206±15) protein decreased in the MRL/lpr group (P＜0.05).After caveolin-1 transfection,the levels of urinary protein [(1 253±249) mg,(2 894±437) mg],BUN [(6.5±1.3) mmol/L,(8.7±1.5) mmol/L],Cr [(78±17) μmol/L,(106±22)μmol/L] were significantly decreased,and the levels of occludin (218±16,114±12),claudin-5 (87±6,60±5)ZO-1 (313±17,98±11) were increased (P＜0.05).Conclusion The expression of caveolin-1 protein in the renal tissues of lupus nephritis increases.Caveolin-1 can reduce the expression of tight junction proteins and contribute to progres-sion of lupus nephritis.

BACKGROUND: Bilateral pedicle screw fixation combined with intervertebral decompression and fusion is a classic surgical approach in treatment of lumbar degenerative diseases, but it can cause ligament and other soft tissue damage of lumbar spine and degeneration of the adjacent segments. While translaminar facet screw fixation has its unique advantages.OBJECTIVE: To compare the clinical efficacy of unilateral pedicle screw fixation combined with translaminar facet screw fixation and bilateral pedicle screw fixation for lower lumbar degenerative diseases.METHODS: Forty-six patients with single-level lower lumbar degenerative disease were enrolled, and were then treated with bilateral pedicle screw fixation combined with intervertebral fusion (group A, n=24) or unilateral pedicle screw along with translaminar facet screw fixation and intervertebral fusion (group B, n=22). Afterwards, the clinical indexes and efficacy were compared between two groups.RESULTS AND CONCLUSION: (1) All operations were performed successfully. The length of incision, operation time,intraoperative blood loss, postoperative drainage volume and cost of hospitalization in the group B were significantly superior to those in the group A (P < 0.05). (2) There was no significant difference in the rate of fusion between two groups (P > 0.05). (3) The visual analogue scale and Japanese Orthopaedic Association scores in both groups at 1 week,3, 6, 12 and 24 months postoperatively were significantly improved compared with baseline (P < 0.05), but the scores had no significant differences between two groups (P > 0.05). (4) To conclude, unilateral pedicle screw fixation combined with translaminar facet screw fixation and bilateral pedicle screw fixation both exhibit satisfactory treatment outcomes,while the former holds little trauma, good stability, high fusion rate and less cost, which is a better choice for lower lumbar degenerative diseases.

OBJECTIVE To sudy drug resistance related gene of carbopenem resistant Pseudomonas aeruginosa and type 1 integrating enzyme gene.METHODS With PCR method to detect and analyze carbopenem resistant P.aeruginosa pertinent metal ?-lactamase IMP,VIM,SPM,GIM genes and cell membrane protein oprD2 gene and six main drug resistance genes of type Ⅰ integrating enzyme gene and five others.RESULTS Fifty one strains of imipenem and meropenem resistant P.aeruginosa SPM,GIM metal enzyme genes were detected to be negative,16 strains of IMP and 5 strains of VIM type metal enzyme were all positive,14 strains of carbopenem resistant P.aeruginosa oprD2 gene were positive,other 37 strains of P.aeruginosa oprD2 gene were negative,7 strains produced metal enzyme and cell membrane protein oprD2 gene were deleted at the same time,49 strains with type Ⅰ integrating enzyme gene intⅠ1 were positive.CONCLUSIONS It is indicated the gene deletion of P.aeruginosa outer membrane protein OprD2 is important mechanism of carbopenem resistant P.aeruginosa,the second is metal enzyme,type Ⅰ integrating enzyme exists largely in P.aeruginosa.This hints the monitoring that drug resistance gene spreads and propagates in bacterium strain must be reinforced.

Objective To study the signal pathway of apoptosis of renal proximal tubular cells (RPTC) caused by cisplatin for prevention of toxic effects of cisplatin on kidney. Methods pcDNA3.1/Hygromycin vector and pEGFP-C3 vector including Bcl-2(Bcl-acta,Bcl-cb5 and Bcl-nt) were co-transfected in RPTC.After treated with cisplatin, Bax was activated,cytochrom C release and apoptosis were analyzed with confocal microscope and immunofluoresence technique. Apoptotic cells stained with Hoechst33258 were also counted and statistically analyzed. Results The percent of cytochrom C release (35.74%) in Bcl-cb5 transfected group was higher than those in Bcl-nt group (18.7%) and Bcl-acta group(24.6%)(P
