Background and purpose: Increasing evidence has indicated that polymorphisms in the microRNA (miRNA, miR) binding site of target gene can alter the ability of miRNA and modulate the risk of cancer. We aimed to investigate the association between a miR-520a binding site single nucleotide polymorphism (SNP) rs141178472 in the PIK3CA 3’UTR and the risk of colorectal cancer in a Chinese Han population. Methods:The polymorphism rs141178472 was analyzed in a case-control study, including 386 colorectal cancer patients and 394 age-and sex-matched controls. The relationship between the polymorphism and the risk of colorectal cancer was examined by statistical methods. Results:Individuals carrying the rs141178472 CC genotype or C allele had an increased risk of developing colorectal cancer (CC vs TT, OR=1.716, 95%CI:1.084-2.716, P=0.022;C vs T, OR=1.258, 95%CI:1.021-1.551, P=0.033). Furthermore, the expression of PIK3CA was detected in the peripheral blood mononucleated cell of colorectal cancer patients, suggesting that mRNA levels of PIK3CA might be associated with SNP rs141178472. Conclusion:These ifndings provide evidence that a miR-520a binding site polymorphism rs141178472 in the PIK3CA 3’UTR may play crucial roles in the etiology of colorectal cancer.

Objective To evaluate the relationship between the let-7 rs10877887 polymorphism and cancer risk in the Chinese population.Methods We searched all relevant studies published on association between the let-7 rs10877887 polymorphism and cancer risk in PubMed,Embase and Wanfang databases up to December 31,2016 were searched.A total of 4 case-control studies comprising 2 754 cases and 3 481 controls were included in this meta-analysis.The pooled odds ratio (OR) and 95% confidence interval (95%CI) were calculated to examine the strength of the association.Sensitivity analyses were performed to assess the stability of the results,publication bias was also assessed.Results The pooled results showed that there was a significant association between the let-7 rs10877887 polymorphism and overall cancer risk under the dominant model (CC+CT vs.TT:OR=0.90,95%CI=0.82-1.00,P=0.048).Conclusion Base on present studies,the results of this meta-analysis indicated that there is a significant association between the let-7 rs10877887 polymorphism and overall cancer risk in the Chinese population,the let-7 rs10877887 polymorphism could decrease the risk of cancer.

Objective: In this study we analyzed the genetic characteristics of echovirus 30 (E-30) VP1 gene sequences from Yunnan province isolated from viral meningitis (VM) cases in 2010-2013. Methods: RT-PCR and VP1 gene sequencing were done for 9 E-30 strains isolated from VM cases in 2010-2013. VP1 gene sequences of E-30 reference strains were downloaded from the GenBank and their nucleotide (nt) and amino acid (aa) diversities were calculated by MEGA 5.1 software, the phylogenetic tree was constructed and the genetic characteristics and molecular epidemiology were analyzed. Results: In 2010-2013, 9 strains of E-30 viruses were detected from 79 VM cases caused by echoviruses, accounting for 11.39%(9/79), the overall positive rate was 1.63%(9/553). Phylogenetic analysis revealed that E-30 strains can be divided into four genotypes (genotype A, B, C and D), and genotype D can be further divided into seven sub-genotypes. Nine Yunnan VM isolates were distributed in D7 sub-genotype, and can be further clustered into 3 branches: 5 strains isolated in 2010 were clustered in branch 1, it is evident that these viruses were responsible for an aseptic meningitis outbreak in Kunming in that year; one 2011 isolate, together with 2013 isolate and one isolate from healthy children in 2010 were clustered in branch 2, these two branches were Yunnan special branches, and two 2011 isolates had the highest homology with 2003 VM outbreaks′ strains isolated from Shandong, Jiangsu, and Zhejiang, showing that these strains may have the same evolutionary sources. Conclusions Nine Yunnan VM isolates were distributed in D7 sub-genotype, and these strains have different evolutionary sources, showing that at different times E-30 viruses in the same sub-genotypes branch might prevail in different areas.

OBJECTIVETo investigate the changes in the number and distribution of myoepithelial cells during atrophy of the rat parotid gland.

METHODSAtrophy of the right parotid was induced by ligating the right stensen duct of rats, histological changes of parotid glands were examined by hematoxylin-eosin (HE) staining during each step of glandular atrophy at the time of 0 (control), 1, 3, 5, 7, 14, 21, 30, 60, 100, and 150 days after ligation. Immunohistochemical labelling was performed to study the changes in number and distribution of myoepithelial cells during atrophy of the rat parotid gland.

RESULTSHistological analysis showed disappearance of the acini at 5 d and gradual decrease and fibrosis of the glandular lobules accompanied by the occurrence of duct-like structures. Quantitative analysis of myoepithelial cells showed significant increase in number up to day 5 after ligation, then followed by gradual increases at a low level, at last it was followed by a rapid decrease after the total number reached the peak in 100 days. In addition, the acini and intercalated ducts were covered by myoepithelial cells ranged from the shape of spindle to stellate during the early phase of atrophy, while spindle-shaped myoepithelial cells were located at the periphery of duct-like structures in the later phase of atrophy.

CONCLUSIONMyoepithelial cells proliferated rapidly up to day 5 after ligation, then followed by gradual increase at a low level, at last it was followed by a rapid decrease after the total number reached the peak in 100 days.

Trousseau′s syndrome(TS) is a complication of cancer-associated thrombosis caused by hypercoagulability. A 58-years female patient admitted to the Affiliated Hospital of Qingdao University on October 2020 and diagnosed with Trousseau′s syndrome was reported. This was a patient with pancreatic malignant tumor. On the second day of admission, the mouth angle was distorted and the speech was vague. Craniocerebral MR showed multiple DWI high signals in the brain parenchyma, and brain MR enhancement showed no abnormal enhancement in the brain parenchyma. The patient was considered to be Trousseau′s syndrome. Using "Trousseau′s syndrome" and "cerebral infarction" as key words, the relevant literature was searched in CNKI, Wanfang and PubMed databases from January 2011 to June 2021, total of 76 cases of Trousseau′s syndrome complicated with cerebral infarction were reported in the literature. Among 77 cases (including one in this study) 36 were males and 41 were females, with a median age of 63 years old. The most common tumor type was lung adenocarcinoma (24 cases, 31.2 %). The mean D-dimer level was (17.3±12.8) mg/L, Craniocerebral CT or MRI showed that 57 cases (74.0 %) had bilateral multiple lesions; and 56 cases received anticoagulant therapy. A total of 68 patients were followed up, with a median survival time of 90 days, and one year overall survival rate was 32.6 %. The study indicates that for cerebral infarction with significantly elevated D-dimer level and multiple vascular involvement, malignant tumors should be considered.
