Three young men died of developmental abnormalities of the AVN,HB and BB were reported.The victims collapesed suddenly and died silently after excitation. A variety of abnormalities were observed in the AVCS including fetal the pattern of the AVN, the malformation of the AVN and thepresence of the accessory routes. The histopathological feature, the mechanism and the precipitatingfactors of sudden death were discussed.

Surgery is the mainstay of lung cancer treatment options.Traditionally,lobectomy has held its place as the gold standard for treating localized lung cancer,while sublobar resection,including wedge resection and segmentectomy,was primarily considered as an alternative,often reserved for patient ineligible to sustain a radical intervention.However,with the widespread application of computed tomography(CT)to clinical practice,the increasing detection rate of pulmonary ground glass nodules(GGNs)has reshaped this landscape.Ground glass opacity(GGO)in persistent lung nodules is an indicative factor of a favorable prognosis,typically corresponding to pathological changes such as atypical adenomatous hyperplasia(AAH),adenocarcinoma in situ(AIS),or adenocarcinomas predominantly featuring a lepidic growth pattern.A large number of retrospective studies have shown that sublobar resection can achieve satisfactory therapeutic outcomes for such lesions.A series of prospective studies from Japan have confirmed that for early-stage lung cancers dominated by GGOs,sublobar resection is also a viable curative surgical option.The follow-up data showed that there was no statistical difference in the survival status of these patients compared with that of pulmonary lobectomy.This article aims to delve into the role of limited lung resection in the context of lung adenocarcinoma presenting with GGO features.

Objective:To establish a multilocus sequence typing (MLST) assay for Corynebacterium ( C.) striatum, explore the population structure and evolution relationship of clinical isolates of C. striatum. Methods:Seven housekeeping genes ( gyrA, gyrB, hsp65, sodA, secA1, rpoB, 16S rRNA) were amplified with PCR by using self-designed specific primers and sequenced. Then, the sequences were assembled with software SeqMan. The gene diversity and gene recombination characteristics were evaluated by using software DnaSP 5.10.01 and Splits tree 4.14.2. The phylogenetic tree and the minimum spanning tree were constructed based on the sequence types (ST) characteristics by using software MEGA 7.0.14 and BioNumerics, respectively. In addition, the genetic evolutionary relationship among STs were analyzed by using software eBURST 3.0. Results:The expected amplification products of seven sites selected in all the test strains were obtained. Splits tree showed that the clustering of all C. striatum strains was consistent, suggesting that gene recombination is the potential driving force for the evolution of C. striatum. All of the 344 C.striatum strains were divided into 72 STs by MLST and 85.7% of the strains formed clonal complexes. CC19 was the predominant clonal complex, whereas ST16 in the clonal complex was detected in the most strains. ST had a certain geographic clustering and a certain correlation with the isolation time. Conclusions:C. striatum showed high genetic diversity in China and CC19 was the predominant clonal complex. The MLST assay established in this study can be used for the typing of C. striatum, but further improvement is needed.

Objective:
To evaluate the clinical value of high-risk humam papillomavirus(HR-HPV) genotyping in diagnosis of cervical lesions.
Methods:
Between December 2012 and March 2015, a total of 4 095 women who were diagnosed as cervical inflammation-related disease were chosen to be evaluated in gynecological clinic at Taizhou Hospital of Zhejiang Province. All the women experienced HPV genotyping, analysis of the epidemiological characteristics of HPV types in Taizhou area and theresult of histopathologic diagnosis of HPV positive women. Logistic regression analysis was used to estimate the risk of HR-HPV genotyping in cervical lesion progression.
Results:
Overall, HPV52 was the most prevalent genotype, followed by HPV16, 58, 39 and 56. Among the women with cervical intraepithelial neoplasm (CIN), HPV16 was the most frequent type, followed by HPV52, 58, 33 and 31. Logistic regression analysis showed that a higher risk of CIN2+ for women infected with HPV16 or HPV33, the regression coefficients OR were 3.670(95%
