Objective To investigate the expressions of CXCR4 in Barrett esophagus (BE), esophageal adenocarcinoma (EADC) and esophageal squamous cell carcinoma (ESCC), and its relationship with pathology, clinical staging and lymph node metastasis. Methods The expressions of CXCR4 in 56 cases of normal esophageal mucosa, 80 BE (including 22 BE with multifocal dysplasia), 25 EADC and 48 ESCC were examined with immunohistochemical method. Results CXCR4 was expressed in most samples of BE (80. 8% ), EADC (68. 0% ) and ESCC (78.4%) without significant difference ( P > 0. 05 ), which was significantly higher than that in normal esophageal mucosa (39. 3%, P <0. 01 ). The level of CXCR4 expression in BE, EADC or ESCC were not related with gender, age, or location of the foci ( P > 0. 05). There was no significant difference in CXCR4 expression between BE without dysplasia or BE with multifocal dysplasia ( P > 0. 05 ). CXCR4 expression level in well-differentiated EADC was significantly higher than that of mild or poorly differentiated (P < 0. 05 ). CXCR4 expression level was higher in EADC with lymph node metastasis than those without ( P < 0. 05 ). CXCR4 level in ESCC with TNM staging grades Ⅲ -Ⅳ was higher than that of grades Ⅰ - Ⅱ, and this variable was also higher in cases with lymph node metastasis than those without (P < 0. 05), so was the case of well and poorly differentiated ESCC (P < 0. 01 ). Conclusion Increased expression level of CXCR4 may be a common feature of EADC and ESCC, which is irrelevant to pathological types. CXCR4 level rises at the stage of BE, which is associated with the degree of tumor differentiation, lymph node metastasis and TNM staging. CXCR4 expression is of guiding significance in the diagnosis of BE, EADC and ESCC, and is the potential drug target.

In order to strengthen the management of disinfection quality of endoscopes, Quality Control Center of Digestive Endoscopy and Nosocomial Infection Control Center of Yunnan Province investigated the diagnosis, treatment, cleaning and disinfection conditions and disinfection quality of digestive endoscopes in some medical institutions of Yunnan Province by web questionnaire from April to May in 2019, and 277 valid questionnaires were finally obtained. SPSS 19.0 statistical software was used to analyze the influencing factors of cleaning and disinfection process and the infection control implementation of digestive endoscopes in 227 secondary and tertiary hospitals. The results showed that the number of decontamination people who had received systematic training in Yunnan Province was significantly lower than that in other areas of China. The hospital level, the number of decontamination personnel, and decontamination methods affected the implementation of cleaning and decontamination process and infection control, while the allocation of decontamination supplies had no effects. It is important to establish an effective mechanism for the normalized implementation of cleaning and disinfection of digestive endoscopes.

OBJECTIVETo explore the effect of Yixintai Granule (YG) on mRNA and protein expression levels of AQP2 in renal medulla of chronic heart failure (CHF) rabbits.
METHODSCHF rat model was established by ear marginal vein injection of adriamycin. Successfully modeled rabbits were divided into the model group, the high (8.4 g/kg), middle (4.2 g/kg), and low dose (2.1 g/kg) YG group, and the Furosemide group (2 mg/kg). Besides, a normal control group was set up. Equal volume of physiological saline was administered to rabbits of the model group and the normal control group by gastrogavage. YG at different doses was administered to rabbits of the 3 YG groups by gastrogavage. The intervention lasted for 4 weeks, once per day. After treatment the urine volume and pathomorphological changes of renal medulla tissue were observed. mRNA and its protein expression levels of AQP2 were detected.
RESULTSCompared with the normal control group, the urine volume decreased significantly, mRNA and protein expression levels of renal medulla AQP2 increased significantly in the model group (all P < 0.01). Compared with the model group, the urine volume increased significantly, and mRNA and protein expression levels of renal medulla AQP2 decreased significantly in all medicated groups (all P < 0.01). Compared with the low dose YG group, the urine volume significantly increased and the mRNA expression level of renal medulla AQP2 significantly decreased in the middle and high dose YG groups (all P < 0.01). The expression level of AQP2 protein significantly decreased in the high dose YG group (P < 0.01). Pathological changes of the renal medulla was the most obviously seen in the model group. But they were alleviated to various degrees in all medicated groups. They were more obviously attenuated in the middle and high dose YG groups.
CONCLUSIONYG could improve CHF possibly through down-regulating mRNA and protein expression levels of AQP2 in renal medulla, and elevating the urine volume.

Objective To investigate the clinical pathological association of FOXQ1 with colorectal carcinoma (CRC) and colorectal adenoma (CRA). Colorectal mucosa specimens were collected between Jane 2007 and June 2009 in the First hospital of Yunnan prorince, and consisted of CRC (n=76), CRA (n=50) and normal (n=48,≥8 cm apart from cancer) tissues. Methods The expression of FOXQ1 in colorectal mucosa with was detected using immunohistochemistry (SP method). PCR amplification and direct DNA sequencing were used to identify FOXQ1 gene mutations in 23 CRC, 22 CRA and 18 normal specimens. Results There was no expression of FOXQ1 in normal specimens. Aberrant expression of FOXQ1 in either CRC or CRA specimens was significantly higher than in normal colorectal mucosa tissue (76.3% vs 0.0%, 26.0% vs 0.0% respectively, P<0.01).Aberrant expression rates of FOXQ1 was significantly higher in CRC than that in CRA (76.3% vs 26.0%, P<0.01). Expression level of FOXQ1 was increase gradually along with the pathological process of colorectal adenoma-carcinoma sequence. In CRC, the aberrant expression of FOXQ1 was not only distributed in nuclear of the tumor cells, but also found in the cytoplasm and the extracellular matrix. For CRC patients, the aberrant expression rates of FOXQ1 in extracellular matrix in Dukes C/D was significantly higher than that in Dukes A/B (61.5% vs 3.3%, 61.5% vs 5.0% respectively,P<0.01);The aberrant expression of FOXQ1 in extracellular matrix in patient with lymph node metastasis was significantly higher than those without lymph node metastasis (61.5 % vs 4.0 %, P<0.01). FOXQ1 gene mutation was only identified in one out of 23 CRC specimens, but not found in 22CRA nor 18 normal colorectal mucosa samples. Conclusions Aberrant expression of FOXQ1 may play an important role in the carcinogenesis of CRC and FOXQ1 gene may be involved in the cancer erosion and lymph node metastasis. FOXQ1 mutation is not the primary cause of aberrant FOXQ1 expression in CRC.
