Nineteen patients with comminuted fractures in middle and distal humerus were treated by dual-plate internal fixation in the prone position in the Department of Orthopaedics,Xiangya Third Hospital of Central South University from January 2005 to June 2007.There were 12 males and 7 females.The average age of the patients was 35.63 years(range 19-65 years),among which 10 cases were left and nine cases were right.All the cases were closed comminuted fractures and 13 cases of them were simple fracture while the other six cases with radical nerve injury.Humerus metal bone plate,with pattern number YJQⅠ(recondition),was used in this study.All patients got the bone union in the average follow-up time of 10 months without complications such as delayed union,nonunion and wound infection.The average healing time was three months.Aitken and Rorabeek score:excellent in 14 cases,good in 3,common in 2,and poor in 0.Totally 89.47% of the patients achieved excellent and good effect.

OBJECTIVE:To establish a method for the simultaneous determination of paeoniflorin,baicalin and imperatorin in Urticaria pill. METHODS:HPLC was performed on the column of Alltima C18 with mobile phase of methanol-water-Phosphoric ac-id(55∶45∶0.2,V/V/V)at a flow rate of 1.0 ml/min,the detection wavelength was 230 nm for paeoniflorin,280 nm for baicalin and 300 nm for imperatorin,column temperature was 30 ℃,and the volume injection was 10 μl. RESULTS:The linear range was 5.40-54.0 μg/ml for paeoniflorin(r=0.999 8),11.29-112.9 μg/ml for baicalin(r=0.999 7)and 24.95-249.5 μg/ml for imperatorin (r=0.999 9),respectively;the linit of quantitation were 5.4、11.2、30.0 ng,the lirnit of detection were 1.8、2.8、7.5 ng;RSDs of pre-cision, stability and reproducibility tests were lower than 2%;recoveries were 95.88%-98.33%(RSD=0.95%,n=6), 96.86%-99.96%(RSD=1.20%,n=6)and 98.07%-100.55%(RSD=0.92%,n=6),respectively. CONCLUSIONS:The method is simple and accurate with strong specificity and good reproducibility,and can be used for the simultaneous determination of paeoni-florin,baicalin and imperatorin in Urticaria pill.

Objective To evaluate the clinical significance of orthotopic continent detenial sigmoid neobladder.Methods 12 patients with bladder cancer were admitted and underwent radical cystectomy and detenial sigmoid neobladder.Results All the 12 patients were followed up for a mean of 18.6 months(range from 6 to 29 months).The blood Cr and BUN levels were both in the normal range without acidosis in all the cases.Only 1 had unilateral ureteral urine reflux during cystography.Of the 12 patients,11 cases(91.7%) achieved continence during daytime;2 cases(16.7%)were incontinent at night,but 1 case could control uri- nation by being woken up at night.The capacity of the neobladder was 220 to 550ml with a mean of 350ml and the maximal pressure of the neobladder during filling was 15 to 55cm H_2O(1cm H_2O=0.098kPa)with a mean of 35cm H_2O.Conclusion As a simple operation the detenial sigmoid neobladder can be performed easily with less complications and more reliable results.This operation may be generally applied in clinical practice.

Objective To summarize the experience of nursing cancer patients with anal fistula treated with blood stem cells transplantation (BSCT). Method 8 critical cancer patients with anal fistula treated with BSCT from August 2013 to November 2014 were intervened by nursing measures such as prevention of constipation and diarrhea , protecting the anus from infection and health education . Results Two patients of them contracted with mild crissum infection , 1 moderate , 0 severe . With the pertinent nursing intervention , no serious complications occurred . The hospital stay was 20~30 d , with an average of ( 24 . 75 ± 2 . 30 ) . Conclusion The nursing measures including preventing constipation and diarrhea, keeping the anus from infection and health education can be effective in avoiding anal fistula infection and its related complications and reducing patients′pain , which are worth clinical promotion .

To investigate the effect of menopause on chemokine receptor CXCR2 expression on monocyte, 21 postmenopausal and 20 premenopausal women were enrolled in the present study. Fasting venous blood was collected, and plasma estrogen levels were determined with radio immunoassay. Monocytes were separated from peripheral blood with gelatin method. Protein expression of chemokine receptor was assayed with flow cytometry and mRNA concentration was measured with RT PCR. The results showed that the levels of plasma estrogen decreased, whereas protein and mRNA expression of chemokine receptor CXCR2 increased after menopause. The plasma estrogen levels were negatively correlated with chemokine receptor CXCR2 expression in monocytes. These data suggested that the changes in CXCR2 on monocytes might contribute to,at least partially,the increased risk of developing coronary heart disease associated with estrogen secretory changes.

Objective To explore the clinical,laboratory,and pathologic manifestations of the interstitial lung disease(ILD)associated with primary Sj(o)gren's syndrome(pSS,pSS-ILD).Methods Clinical data of 15 patients with pSS-ILD admitted to our hospital from 2006 to 2008 were collected and the different features were compared with 18 patients with pSS without ILD.Eight patients with pSS-ILD were followed up and observed the changes of high-resolution computed tomography (HRCT).Results The age at onset was later in pSS-ILD[(57±11)years]than in pSS without ILD[(43±11)years](P<0.01).The initial symptoms in six of patients with pSS-ILD were cough,expectoration,chest distress or dyspnea upon exertion.The respiratory clinical manifestations,circulationsystem involvement and pulmonary artery hypertension (PAH) were more common in pSS-ILD than in pSS without ILD(P<0.01).Compared with patients with pSS without ILD,patients with pSS-ILD had significantly higher serum IgG level(P<0.01).The common findings of HRCT included reticular changes,irregular linear hyper-attenuating areas,and nodules.Pleural involvement was found in 8 patients,honeycomb change in 5 patients and PAH in 3 patients.After treated for 6 months of 8 patients,radiological findings improved in 4 patients,stable in 2 patients,and worse in 2 patients.The comlnon histological findings included focal fibrosis in alveolar wall and alveolus with and alveolar space inflammatory cell infiltration,interstitial inflammation with mulifocal lymphocyte infiltration.One patient had the pathological changes of nonspecific interstitial pneumonia(NSIP).Conclusion The age at onset of pSS-ILD is late and tends to produce respiratory symptoms and prone to have circulationsystem involvement such as PAH and elevated serum IgG level.Honeycomb change in HRCT can be seen in one third of patients and most patients can improve after treatment,however.NSIP can be observed in histopathologieal

This method is simple, fast, and can be used for these minerals containing sulfate class the qualitative identification and quality control of Chinese traditional medicine.

Objective:To investigate the expression of microRNA-199a/b-3p (miR-199a/b-3p) in hepatocellular carcinoma ( HCC) tissues,and to explore the relationship with clinical outcomes. Methods: Real time quantitative PCR technique was used to measure the expression of miRNA-199a/b-3p in HCC tissues. The correlation between miR-199a/b-3p expression and the clinic pathological features of patients were analyzed. Results: Comparing with adjacent control, miRNA-199a/b-3p presented lower expressions in HCC tissues (P<0. 05);lower miR-199a/b-3p was found correlated with metastasis and poor survival. Conclusion:MiR-199a/b-3p take a crucial role in HCC metastasis and recurrence.

Objective:To analyze the effect of PAK4 interruption by microRNA-199a/b-3p (miR-199a/b-3p) on migration and invasion of hepatocellular carcinoma (HCC).Methods: To test targeting of PAK4 by miR-199a/b-3p,we used luciferase assay in HEK293T cells cotransfected miR-199a/b-3p mimcs and pmirGLO-PAK4 3′UTR.The expression of PAK4 in SMMC-7721 transfected with miR-199a/b-3p was detected by Western blot.The biology behaviors of SMMC-7721 cells transfected with miR-199a/b-3p or PAK4 Si were analysed by cell migration assay and invasion assay.Results:MiR-199a/b-3p could suppress the mRNA and protein ex-pression of PAK4 by targeting PAK4 3′UTR,and the downregulating PAK 4 expression suppress the migration and invasion of SMMC-7721 cells.Conclusion: MiR-199a/b-3p could suppress the expression of PAK 4, which are considered key HCC suppressors and inhibit the migration and invasion of HCC cells.
