Objective Implanting surgical meshes to support breast in periareoler mammaplasty shows an excellent prospect.But shrinking of the mesh and the adhesion formation affected the postoperative shape and palpation of the breast.The aim of this study was to compare biocompatible properties of four different polypropylene meshes (Prolene(R) ; Vypro Ⅱ(R) ; Premilene Mesh (R) and Premilene Mesh LP(R)) and to discuss the inclusion criteria of meshes in this technique.Methods The study was carried out in pigs.Four different polypropylene meshes were implanted subcutaneously in belly.90 days after implantation the mesh samples were explanted,and complications,foreign-body reaction,collagen fiber and elastic fiber formation were observed,as well as ultrastructures for the biocompatible properties.Results The biocompatible properties of each mesh were different.The foreign-body reactions determined the biocompatible properties,and affected the postoperative shape greatly.Conclusions Premilene Mesh LP o as a newer low-weight polypropylene mesh,has superior properties to the others.

This article was aimed to study the factors associated with sleep quality of anger-out and anger-in population based on the frequent pattern-tree (FP-Tree) growing algorithm with data mining. The algorithm of structuring frequent model FP-tree and mining frequent itemsets were designed. The database information scanned was recorded by using FP-Tree growing algorithm through state-trees. The frequent itemsets met minimum support required was generated through reducing the search space of project sets and scanning database only one. The data mining of all factors associated with emotional diseases was actualized. The results showed that factors associated with sleep quality of anger-out and anger-in population were disturbance in respiration, cough or snoring, feeling cold, hot or nightmares. The total time for program analysis was 2 seconds. It was concluded that data mining algorithm based on FP-Tree frequent itemsets can effectively realize the useful information receiving from factors associated with emotional diseases.

Objective The aim of this paper is to know about the pollution of microcystin-LR(MC-LR)in Fenhe First reservoir and Fenhe Second reservoir in Taiyuan and provide reference for making the policy of prevention microcystin-LR pollution.Methods During the low water period(May,2005)and common period(Oct,2005),5 liter water was sampled in the entrance,the center and the exit in Fenhe First reservoir and Fenhe Second reservoir respectively.The concentrations of MC-LR in two reservoirs were determined by the high-performance liquid chromatography(HPLC).Results The average concentration (0.875 ?g/L)of MC-LR in low water period was 3 time of that(0.283 ?g/L)in common period in Fenhe First reservoir.The average concentration(0.815 ?g/L)of MC-LR in low water period was 17 time of that(0.048 ?g/L)in common period in Fenhe Second reservoir.The level of MC-LR in the entrance was the highest,that in the exit was the lowest,that in the center was middle. The concentration of MC-LR of the entrance in low water period was more than the MC-LR limit(1 ?g/L)in Life drinking water hygienic guide(2001).Conclusion MC-LR pollution has been found in Fenhe First reservoir and Fenhe Second reservoir and the pollution is serious in low water period.

The on-line monitor for the changes in the content of baicalin in Scutellariae Radix formula particles during the extraction process was conducted by using near infrared spectroscopy (NIR). High performance liquid chromatography (HPLC) was used as a reference method. Kennard-Stone (KS) was used to divide sample sets, so as to compare different pretreatment methods. The synergy interval partial least squares (SiPLS) was used to screen out modeling wave band to establish partial least-squares models. The relative error method was applied to predict forecast set samples of Scutellariae Radix in three extraction phases. The results showed that the model established by Savitzky-Golay smoothing with 11 points (SG11 points) was the best, with the root mean square with cross validation (RMSECV), root mean square error of correction (RMSEC) and root mean square error of prediction (RMSEP) of baicalin of 0.092 7, 0.134 4 and 0.114 8, respectively, the determination coefficient R2 of greater than 0.99, and the relative error of baicalin content of less than 5%. This indicates that the on-line near infrared reflectance spectroscopy could be applied in on-line monitor and quality control of the extraction process of Scutellariae Radix formula particles.

To study the function of expelling water retention with drastic purgative of different polarities of Kansui Radix stir-baked with vinegar on the cancerous ascites model rats, the furosemide was taken as positive control drug, and the cancerous ascites model rats were respectively orally administered with different polarities of Kansui Radix stir-baked with vinegar for 7 d. The amount of urine and ascites, the level of urinary sodium, potassium, chloride ion and pH, and the content of PRL1, AII, ALD in serum were investigated. Compared with model groups, ethyl acetate extract group showed a decreasing trend in ascites; the amount of urine of showed a significant increase (P < 0.05); the level of urinary sodium, potassium, chloride ion (P < 0.05, P < 0.01), pH (P < 0.05), and the content of PRL1, AII, ALD in serum all showed a significant decrease (P < 0.01). The effects of petroleum ether extract and n-butanol extract were weaker than that of ethyl acetate extract. The water exact was the weakest. The results showed that ethyl acetate extract is the active part of Kansui Radix stir-baked with vinegar on the function of expelling water retention with drastic purgative on the cancerous ascites model rats, alleviating the water-electrolyte disorder and body fluid acid-base imbalance, regulating the renin angiotensin aldosterone system.

Objective To compare the role of CTE and CE on the diagnosis of small bowel diseases and evaluate their advantages in patients with different indications.Methods Patients underwent both CTE and CE(interval time <2 weeks)at our institution in recent 3 years were enrolled.The positive detection rates,lesion properties and characteristics of CTE and CE were compared.The diagnostic accuracy of combined method was also analyzed.Results A total of 47 patients were enrolled and the indications included suspected or established Crohn′s disease (28 cases),unexplained abdominal pain (14 cases), obscure gastrointestinal bleeding(3 cases),insufficient small bowel obstruction(1 case)and protein losing enteropathy(1 case).Diagnostic yield of CTE and CE for whole small bowel disorders showed no significant difference(CE 83.0% VS CTE 78.7%,P =0.791).For suspected or established CD,CE had a higher diagnostic accuracy than CTE (78.6% VS 35.7%,P =0.002 ),especially in detecting lesions in the jejunum(CE 50.0% VS CTE 7.1%,P =0.002).The diagnostic accuracy reached 100.0% when two meth-ods were combined.For unexplained abdominal pain,no significant difference was found in the diagnostic ac-curacy of CE and CTE(CTE 42.8% VS CE 50.0%,P =1.000).Diagnostic accuracy of combining CTE and CE was 85.7%.Conclusion CTE and CE are both valuable in detecting small bowel lesions.For pa-tients with suspected or established CD,CE is better than CTE.For patients with unexplained abdominal pain,a combination of CTE and CE may be a better strategy than use CTE or CE alone.

BACKGROUND:Deep vein thrombosis and pulmonary embolism are certainly related to seasons.
OBJECTIVE:To analyze whether there is a seasonal pattern for deep venous thrombosis (DVT) after total hip and knee arthroplasty.
METHODS:We retrospected 866 patients (1 114 joints) underwent total hip and knee arthroplasty. There were 506 cases of total hip arthroplasty, including 287 male cases and 219 female cases, and 608 cases of total knee arthroplasty, including 133 male cases and 475 female cases. The average age was (60.98±0.87) years. After arthroplasty, patients were given color Doppler ultrasound in the deep veins of the lower limbs and pelvis to analyze the correlation between occurrence of deep vein thrombosis and seasons.
RESULTS AND CONCLUSION:There was a significant difference in the incidence of deep vein thrombosis in summer and winter (χ2=7.190, P=0.007), in summer and spring (χ2=6.995, P=0.008), as wel as in summer and autumn (χ2=5.663, P=0.017). No statistical differences were tested in spring and autumn, in autumn and winter, and in spring and winter (P>0.05). These findings indicate that there is a seasonal variation of deep venous thrombosis after arthroplasty, and the highest incidence of deep vein thrombosis is in winter.
