Objective To understand the screening results and positive lesion situation of colonoscopy screening among high risk urban population of colon cancer in Chongqing Nan'an District to provide a basis for the community heath guidance.Methods The high risk subjects of colon cancer screened according to the item of the Early Diagnosis and Early Treatment of China Urban Cancer and in our center for completing colonoscopy screening during 2013-2016 were collected and analyzed on the positive rates of various lesions.Results A total of 435 subjects were included,141 positive cases were found with the total positive rate of 32.41％ (141/435),in which 75 cases were male positive with the positive rate of 47.47％ (75/158),and 66 cases were female positive with the positive rate of 23.83 ％ (66/277),the polyps detective rate was 28.27 ％ (123/435),tumor-like lesion detective rate was 7.59％(33/435),the adenocarcinoma detection rate was 0.46％ (2/435);the total positive rate of male was higher than that of female(x2 =25.669,P＜0.01).Conclusion The sequential screening mode in which the high risk population preliminarily screened out by community then performs colonoscopy examination has an important significance for discovering the intestinal tract lesion.

OBJECTIVETo explore the effect of Salvianolate on myosin heavy chain (MHC) in cardiomyocytes of congestive heart failure (CHF) rats.

METHODSSixty male SD rats were divided into 6 groups according to random digit table, i.e., the normal control group (NCG), the model group, the Captopril group (CAG), the low dose Salvianolate group (LSG), the high dose Salvianolate group (HSG), the Captopril and high dose Salvianolate group (CSG), 10 in each group. CHF rat model was established with peritoneal injection of adriamycin in all rats except those in the NCG. Equal volume of normal saline was peritoneally injected to rats in the NCG, once per week for 6 successive weeks. Corresponding medication was started from the 5th week of injecting adriamycin. Rats in the CAG were administered with Captopril solution at the daily dose of 10 mg/kg by gastrogavage. Rats in the LSG and the HSG were administered with Salvianolate solution at the daily dose of 24.219 mg/kg and 48.438 mg/kg respectively by gastrogavage. Salvianolate was dissolved in 2 mL 5% glucose solution and administered by peritoneal injection. Rats in the CSG were peritoneally injected with high dose Salvianolate solution and administered with Captopril solution by gastrogavage. Two mL normal saline was peritoneally injected to rats in the model group, once per day for 8 successive weeks. Eight weeks later, the cardiac function and myocardial hypertrophy indices were detected by biological signal collecting and processing system. mRNA expression levels of alpha-MHC and beta-MHC in cardiac muscle were detected by fluorescence quantitative PCR. Expressions of protein kinase C (PKC) in cardiac muscle were detected by Western blot.

RESULTSCompared with the normal control group, heart mass index (HMI) and left ventricular mass index (LVMI) obviously increased in the model group (P < 0.01). Compared with the model group, HMI and LVMI decreased in HSG, CAG, and CSG groups (P < 0.05, P < 0.01). It was more obviously lowered in the CSG group than in the CAG group (P < 0.05). Compared with the NCG, the mRNA expression level of alpha-MHC in cardiac muscle decreased, the mRNA expression level of p-MHC and the expression of PKC in cardiac muscle increased in the model group (P < 0.01). Compared with the model group, the mRNA expression level of alpha-MHC in cardiac muscle was increased, and the mRNA expression level of beta-MHC and the expression of PKC in cardiac muscle were decreased in HSG, CAG, and CSG groups (P < 0.05, P < 0.01). There was statistical difference between the CSG group and the CAG group (P < 0.05).

CONCLUSIONSSalvianolate could up-regulate the mRNA expression level of alpha-MHC, and down-regulate the mRNA expression level of beta-MHC in cardiac muscle. Its mechanism might be related to decreasing the expression of PKC.

In comparison with the radical resection for rectal cancer, the local excision of rectal cancer is associated with advantages of less trauma, lower risks, anal sphincter preservation, and sexual and urinary function preservation. Being one of the local excision techniques for rectal cancers, transanal endoscopic microsurgery(TEM) becomes increasingly prevailing worldwide in recent years. As compared to traditional local excision procedures, TEM has been proven to improve the operative exposure and provide more adequate operating space. In addition, the TEM is equipped with multiple well-crafted surgical instruments that offer superior performances, which allows delicate surgical dissection and precise tumor excision. TEM provides surgeons with perfect technical support to decrease the chance of or to prevent insufficient removal of the lesion, which leaves an unsafe or positive surgical margin. Good therapeutic results are based on the accurate preoperative evaluation and careful selection of the patient, as well as strict adherence to the indications of this procedure. The best indications for TEM procedure include rectal adenomas with high-grade dysplasia (Tis stage), medium- or low-risk T1 rectal cancers, and cancers that only infiltrate into the Sm1 and Sm2 layers of the submucosa. Patients of T2 and T3 rectal cancers acquiring marked tumor downstaging (or tumor size decreases by more than 50%) after the neoadjuvant therapy may also be candidates for TEM local excision in clinical research studies. TEM technique enables a locally radical excision of the lesion, which is the key to prevent the postoperative recurrence.

Batch and continuous fermentation were adopted to investigate the effect of specific growth rate and amino acid components on RNA accumulation in Candida tropicalis ATCC 20408 in fermentation medium ( FM), yeast peptone dextrose medium (YPD), molasses fermentation medium ( MFM) and FM without corn steep liquor. The data showed that obvious differences in intracellular RNA accumulation were observed at different cell growth phases in bath fermentation prosess, and RNA level reached 11. 8% (g-RNA /g-DCW) during exponential phase, and only 6.9% during stationary phases. It was also found that intracellular RNA accumulation increased with the increase of specific growth rate in continue fermentation prosess, and the highest RNA level reached 15. 6% with the glucose conversion rate of 42. 8% at the dilution rate of 0. 5 h-1. Furthermore, the data showed that RNA lever was notably increased in batch fermentation process when amino acids or peptone was added into the fermentation medium containing no corn steep liquor. Taken together, it was reported for the first time that specific growth rate and amino acid components plays a leading role on the intracellular RNA accumulation in C. tropica lis, and specific growth rate is more important.

binding,cellular organelle membrane,and cellular metabolic process of GO enrichment.For the KEGG pathways, the target genes mainly concentrated on the focal adhesion pathway.Conclusion There is a different expression of novel microRNA between SLE and NC groups.The target genes from differently-expressed novel microRNA may play an important role in the pathogenesis of SLE and clinical symptoms and may be the unique target for further research.
