Objective To investigate the effects of CNTN-1 on the invasion and migration of human esophageal cancer EC9706 cells and the possible mechanism.Methods The expression of CNTN-1 in human esophageal cancer EC9706 cells was measured by qPCR and Western blot.After transfection with CNTN-1 siRNA or CNTN-1, the cells were divided into control group, scrambled siRNA group, CNTN-1 siRNA group, pcDNA3.1-vector group and pcDNA3.1-CNTN-1 group.Cell proliferation, invasion and migration were respectively analyzed by BrdU assay and Transwell test.The expression of MMP-2 and MMP-9 were detected by qPCR and Western blot.Results The mRNA and protein expression of CNTN-1 were significantly upregulated in EC9706 cells.Compared with control, cell proliferation, invasion and migration, as well as the expression of MMP-2 and MMP-9 were significantly decreased by CNTN-1 siRNA, while they were increased by CNTN-1 overexpression (P<0.05).ConclusionsCNTN-1 can influence the invasion and metastasis of esophageal cancer cells through the regulation of the expression of MMP-2 and MMP-9.

Background and purpose: Previous studies have confirmed that the expression of leucine-rich repeat-containing 3B (CLRRC3B) was significantly decreased in different human cancers, which was also associated with the migration and invasion of cancer cells. The aim of this study was to explore the potential mechanism of LRRC3B in the development of esophageal cancer. Methods: The LRRC3B expression was detected in 60 cancer tissues and 60 adjacent non-neoplastic tissues by immunohistochemistry. The mRNA and protein expression of LRRC3B in Eca109 and HEECs were detected using real-time fluorescence quantitative polymerase chain reaction (RTFQ-PCR) and Western blot, respectively. Eca109 cells with different treatments were divided into three groups:normal group, negative control group (transfected with pCMV6 plasmid), overexpression LRRC3B group (transfected with pCMV6-LRRC3B plasmid). Transwell assay was used to measure the migration and invasion of Eca109 cells in different groups. The protein levels of E-cadherin, N-cadherin, Vimentin and p-Akt were determined by Western blot. Results: The expression of LRRC3B in esophageal cancer tissues was lower than that of non-cancerous tissues, as well as the expression of LRRC3B in Eca109 was decreased compared with that of normal esophageal epithelial cell line HEEC. Overexpression of LRRC3B significantly inhibited Eca109 cells migration and invasion, upregulated the expression of E-cadherin and decreased the expression of N-cadherin and Vimentin. Moreover, overexpression of LRRC3B significantly inhibited the phosphorylation of Akt in Eca109 cells. Conclusion: The expression of LRRC3B was decreased in esophageal cancer. Overexpression of LRRC3B can efficiently inhibit the EMT progression in esophageal cancer cells by suppressing PI3K/Akt signaling pathway.

Objective To investigate the clinical effect of tiotropium bromide combined with Seretide in treatment of moderate to severe chronic obstructive pulmonary disease( COPD) patients. Methods From Jan. 2012 to Oct. 2013,76 severe COPD were selected as our subjects and they were randomly divided into the control group(38 cases)and research group(38 cases). Patients in control group were used Seretide(1 time both at morning and night,the does was 50 μg/ 500 μg),and in research group were given tiotropium bromide with thiophene beside Seretide(1 time every day). The two groups were received routine treatment,including anti infection,cough and asthma,according to the change of illness. The pulmonary function,blood gas index, respiratory symptoms and 6 minutes walking distance(6 MWD)were recorded. Results Forced expiratory volume in one second( FEV1),forced vital capacity( FCV),FEV1 / FCV of patients in research group after ftreatment were(2. 22 ± 0. 48)L,(3. 28 ± 0. 32)L,(66. 23 ± 9. 22)% respectively,higher than those in the control group,and the differences were significant((1. 78 ± 0. 35)L,(2. 85 ± 0. 47)L,(56. 83 ± 7. 85)% ;t= 5. 39,4. 66,4. 78;P < 0. 01). Partial pressure oxygen(PaO2 )of patients in research group after treatment was (72. 83 ± 5. 28)mmHg,significantly higher than that of control group((65. 36 ± 3. 22)mmHg). However, partial pressure of carbon dioxide( PaCO2 )was(43. 28 ± 3. 52)mmHg,significantly lower than the control group((48. 76 ± 2. 85)mmHg;t = 7. 44,7. 45,P < 0. 01). Dyspnea( MMRC)score in research group was (1. 38 ± 0. 32),lower than the control group(1. 76 ± 0. 35),and 6 MWD was(428. 36 ± 32. 85)m,higher than that of control group((398. 65 ± 28. 38)m;t = 4. 93,4. 21,P < 0. 01). Conclusion The treatment plan of tiotropium bromide combine with Seretide on moderate and severe COPD patients is proved with the better clinical effect and it can improve the partial pressure of oxygen and then promote repair mechanism of lung injury as well as promote the quality of life of patients with ascension.

Objective:To study the role of autophagy-associated gene regulation FK506 binding protein 1A (FKBP1A) in the regulation of head and neck squamous cell carcinoma (HNSCC).Methods:TCGA was used to analyze the gene expression difference between HNSCC and normal tissues, and the DAVID was employed to perform functional annotation of differently expressed autophagy-associated genes enrichment in HNSCC. Univariate and multivariate Cox regression analysis was used to find genes that were meaningful for the prognosis of HNSCC patients in TCGA; the Gene Expression Comprehensive Database (GEO) was employed to verify the prognosis of the screened gene; the prognosis of HNSCC patients was analyzed by Kaplan-Meier Plotter.Results:Compared with the normal tissues samples, a total of 38 genes significantly changed in HNSCC tissues. These differential genes were mainly distributed in autophagy-associated pathways in biological processes (BP), cellular components (CC) and molecular functions (MF) in GO analysis. Univariate and multivariate Cox regression analysis found that 18 autophagy-associated genes were significantly correlated with the prognosis of HNSCC patients in the TCGA database. Among them, the high-risk genes were verified in the GEO database, and found that FKBP1A was closely related to the prognosis of HNSCC patients. Immunohistochemistry and quantitative reverse transcription polymerase chain reaction (qRT-PCR) assays showed that the expression of FKBP1A in patients with HNSCC was higher than that of the corresponding adjacent tissues, and was closely related to the stage of HNSCC.Conclusions:This study used integrated bioinformatics methods to study the role of autophagy-associated genes in the occurrence and development of HNSCC. Moreover, the screened biomarker, FKBP1A, is closely related to the prognosis of HNSCC, and provide the theoretical basis for the pathogenesis and potential treatment of HNSCC.

Bovine adenovirus type 3 (BAdV3) is being used in the development of potential vehicles for gene therapy and vectored vaccine. To that end, a more comprehensive description of BAdV3 biology is essential. In this study, we focused on the role of pIX in BAdV3 virion rescue after full-length BAdV3 genome transfection. Initially, pIX deletion or initiation codon mutation abolished the production of progeny virions, which suggested that pIX was essential for the rescue of BAdV3 containing a full-length genome. Moreover, through transfection of a panel of pIX mutant BAdV3 genomes, we observed that the conserved N-terminus and the putative leucine zipper element (PLZP) were essential for virion rescue, whereas the C-terminus following the coiled-coil domain was non-essential. In addition, swap of the PLZP element and its following region of BAdV3 pIX to corresponding domains of human adenovirus type 5 (HAdV5) did not affect virion production, whereas swap of the entire pIX abolished production of progeny virions. We suggest that failure of the full-length BAdV3 pIX swap might be due to species specificity of its N-terminus region before the PLZP element.

ObjectiveTo analyze the changing trend of cerebrovascular disease burden in Minhang District of Shanghai from 1996 to 2021， and to provide scientific evidence for government to formulate targeted cerebrovascular disease prevention and control strategies. MethodsMortality， years of life lost（YLL）， years of lived with disability（YLD） and disability⁃adjusted life years（DALY） were used to evaluate the burden of cerebrovascular diseases in Minhang District. Joinpoint linear regression was used to analyze the trend of disease burden. ResultsFrom 1996 to 2021， the YLL rate of cerebrovascular diseases in Minhang District showed a downward trend （whole population： APC=-1.69%， t=-6.9， P<0.05）， The YLD rate of cerebrovascular diseases showed a slow upward trend （whole population： APC=1.17%， t=3.5， P<0.05）， The DALY rate of cerebrovascular diseases showed a downward trend， and fluctuated since 2003 （whole population： APC= -1.43%， t=-5.6， P<0.05）. The YLL rate of cerebrovascular diseases in men was higher than that in women， and the YLD rate of cerebrovascular diseases in women was higher than that in men. After 2014， the DALY of cerebrovascular diseases in men was higher than that in women. With the increase of age， the burden of cerebrovascular diseases increased， and the burden of disease increased significantly in the age group above 70. ConclusionThe burden of cerebrovascular diseases in Minhang District is at a high level， and there are differences in age， gender and other aspects. Measures such as screening， intervention and rehabilitation need to be improved to reduce disability and premature death caused by cerebrovascular diseases and to reduce the burden of cerebrovascular diseases on individuals， families and society.

ObjectiveBased on the quality evaluation experience of "it is better to have a fragrant and strong aroma" summarized by materia medica of past dynasties， the chemical components of Sojae Semen Nigrum（SSN） and Sojae Semen Praeparatum（SSP） were systematically compared and analyzed， and the main fermentation products in different fermentation time were quantitatively analyzed， so as to clarify the transformation law of internal components in the processing process and provide scientific basis for the modern quality control of SSP. MethodUltra performance liquid chromatography-quadrupole tandem time-of-flight mass spectrometry（UPLC-Q-TOF-MS） was used for the structural identification of the chemical constituents of SSN and SSP， and with the aid of Progenesis QI v2.3 software， the negative ion mode was employed for principal component analysis（PCA） pattern recognition， and the data were analyzed with the aid of orthogonal partial least squares-discriminant analysis（OPLS-DA） for two-dimensional data to obtain S-plot， and components with |P|>0.1 were selected as the differential constituents. The contents of isoflavonoids in SSP during fermentation was determined by UPLC， and the samples were taken every 8 h in the pre-fermentation period and every 2 d in the post-fermentation period， and the dynamic changes of isoflavonoid contents in different fermentation stages were analyzed. The contents of amino acids and nucleosides in SSP and SSN from different fermentation stages were quantitatively analyzed by phenyl isothiocyanate（PITC） pre-column derivatization and high performance liquid chromatography（HPLC） gradient elution， and the contribution of flavor substances to the "delicious" taste of SSP was discussed by taste intensity value（TAV）. ResultA total of 19 kinds of differential components were screened out， mainly soybean saponins and isoflavones， and their contents decreased significantly or even disappeared after fermentation. In the pre-fermentation process of SSP， glycoside bond hydrolysis mainly occurred， and isoflavone glycosides in SSN were degraded and converted into the corresponding aglycones， the content of flavor substances such as amino acids increased gradually. In the post-fermentation process， protein degradation mainly occurred， after 8 d of post-fermentation， the content of isoflavones was basically stable， while the total content of amino acids increased by 8-40 times on average. Different amino acids form the special flavor of SSP， such as the TAV of glutamate is always ahead of other flavor substances， and sweet substances such as alanine and valine have made relatively great contributions to SSP. ConclusionBased on the law of constituent transformation， combined with the traditional evaluation index of "fragrant and strong"， it is difficult to control the fermentation degree of SSP by the existing standards in the 2020 edition of Chinese Pharmacopoeia. It is suggested that description of the characteristics of SSP be refined and changed to "fragrant， delicious and slightly sweet"， and at the same time， the post-fermentation index compounds such as glutamic acid， alanine and valine should be added as the quality control indicators of SSP， so as to standardize the production process and improve the quality of SSP.
