Objective To investigate the relationship of apolipoprotein E (ApoE) gene polymorphism and the suscepti-bility of childhood obesity Methods The database of PubMed, OVID, Science online, BMJ, Springer Link, Medlink, China Journal Full-text and Wanfang were systematically searched. The studies regarding ApoE polymorphism associated with child-hood obesity from March 1996 to March 2013 were included in the research. The data were extracted, evaluated and hetero-geneity tested using software Rev Man 5.0. Results A total of 84 related literature were retrieved, and 9 of them were eligible with 767 obese children and 867 normal children included. According to the heterogeneity test results, the relationship between ApoE gene allele,ε2,ε3,ε4 and childhood obesity occurs was analyzed by means of ifxed or random effect model. The results indicated that, comparing to children with normal body mass, the OR value and 95%CI of ApoE allele geneε2,ε3,ε4 in obese children were 1.10 (0.85, 1.43), 0.66 (0.55, 0.80), and 1.82 (1.31, 2.52) respectively. The differences ofε3 andε4 between normal and obese children were signiifcant (P<0.001) but notε2 (P=0.45). The sensitivity analysis in each study was stable and the funnel graphics were basically symmetric. Conclusions ApoE gene polymorphism is closely related to childhood obesity withε3 allele as a protective factor whileε4 allele as a risk factor.

Objective To retrospectively analyze management of chronic lateral ankle instability and evaluate its clinical results. Methods There were 74 patients including 43 males and 31 females at age range of 15-63 years (mean 39 years). All patients had at least half year of disease history, more than twice repeated strains and over six weeks of conservative management. Of all, 41 patients were trea-ted with surgical operations including modified Brostrom in 12 patients, Myerson in eight and Chrisman-Snook in 21. The aasoeiated pathological problems should be treated at the same time, ie, tenedesis for the peroneal tendon subluxations in six patients, Achilles tendon lengthening in nine, lateral shift of cal-caneal osteotomies in eight and clearance and holes-making for the osteochondral lesions in 13. Results Of all, functional instability was alleviated in 21 patients through conservative treatment before surgery. Of 53 patients with either functional or mechanical instability, 10 patients showed symptomatic relief, two refused surgical operation and the remained 41 patients were treated surgically. Thirty-nine patients trea-ted surgically and 28 treated conservatively were followed up for 6-91 months. The Roos Functional Out-come Score was used for validating the results. The average value of the ankle functional outcome was 86.24 and 97.34 respectively following operation and conservative management. Conclusions The full examination is needed to remove any possible pathological factors for the patients with chronic lateral ankle instability. The surgical operation can obtain satisfactory functional recovery of the ankle if the conserva-tive management is failed.

Objective To investigate the distribution of human papillomavirus (HPV) type 16 in women cervical infection in eastern Guangzhou, polymorphism of E6/E7 gene and association of gene dosage with disease progression. Methods Flow-through hybridization and gene chips were applied in HPV sub-type identification to screen out HPV-16 positive samples from cervical epithelium samples. HPV-16 E6/E7 gene was amplified through PCR with specific primers. The PCR products were cloned into pMD18-T vectors and fragments were determined through sequencing. Polymorphism analysis were performed through align-ment tools. Fluorescence quantitive PCR were used for the detection of viral E6 gene and L1 gene. Results Thirty-six (4.5%) HPV-16 positive samples were screened out through flow-through hybridization from 806 cervical epithelium samples. HSIL and above happened in 18 (50.0%) of the 36 HPV-16 positive patients. Within E6/E7 gene sequences from 7 selected samples, we found 15 sites with variances and 8 of them would cause coding amino acid change. HIL group (A, 11 cases) and LSIL group (B, 14 cases) possess significantly different gene dosage of both viral E6 gene and LI gene (P <0.05). The ratios of L1/E6 be-tween the 2 groups was not significantly different(P=0.19). Conclusion HPV-16 cervical infection oc-curs in 4.5% women (17-62 years old) in eastern Guangzhou. HIL or above accompany with half of the HPV 16 infected women. Viral load is probably associated with cervical HSIL, though L1/E6 ratios do not suggest viral integration.

Objective To investigate the relationship between β3 - adrenergic receptor(β3 - AR)gene poly-morphism and the susceptibility of occurrence in children obesity. Methods The database of PubMed,Web of Science,Springer Link,Medlink,SinoMed,Wanfang,VIP and CNKI were systematically browsed online. The study re-ports regarding β3 - AR associated with children obesity from January 1995 to February 2014 were included in the re-search. The data were extracted,evaluated and heterogeneity tested by using software RevMan 5. 1. Results A total of 162 related literature were retrieved,and 9 of them were eligible with 1 494 obese children and 1 623 normal children were included. Allele T compared with C,the differences between the study group and the control group were statistical-ly significant(P < 0. 05),the findings from the same TC + CC compared to TT and TC compared with TT + CC were similar. Japanese research findings were similar to those of China,but the differences between the study group and the control group had no statistical significance(P ﹥ 0. 05)in Hungary. The sensitivity analysis in each study was stable and the funnel graphics were basically symmetric. The results of sensitivity analysis and publication bias diagnostics demonstrated the reliability and stability of the Meta analysis. Conclusions TC + CC/ TT,TC/ TT + CC genotype and allele T/ C are related to the occurrence of childhood obesity in China,Japan,but there is no significant correlation with childhood obesity in Hungary. There are regional difference between β3 - AR gene polymorphism and genetic susceptibility to children obesity.

Objective To evaluate the relationship between vitamin D receptor(VDR) (rs731236)single nucleotide polymorphisms and genetic susceptibility to overweight/obesity in school-age children of Han and Kazakh in Xinjiang Uygur Autonomous Region.Methods The VDR gene rs731236 genotypes were detected by using polymerase chain reaction-restriction fragment length polymorphism method in 250 overweight/obesity school-age children(127Han,123 Kazakh) and 255 healthy controls(131 Han,124 Kazakh) as well.Results (1)There were statistically significant differences in the frequencies of rs731236 genotypes and alleles between the healthy controls of Han and Kazakh (x2 =9.904,P =0.005;x2 =9.312,P =0.002).(2)There were statistically significant differences in the frequencies of TT/Tt + tt genotype and the alleles between the overweight/obesity cases and healthy controls of Kazakh (x2 =3.891,P =0.049 ; x2 =5.871,P =0.015).But the difference in frequencies of rs731236 genotypes and alleles between the overweight/obesity cases and controls of Han were not statistically significant (x2 =0.064,P =0.800 ; x2 =0.190,P =0.663).(3)There were statistically significant differences in the frequencies of TT/Tt + tt genotype and alleles between the overweight/obesity cases and healthy controls of male school-age children of Kazakh (x2 =5.25,P =0.02;x2 =4.57,P =0.03),but the differences in frequencies of rs731236 genotypes and alleles between the overweight/obesity cases and controls were not statistically significant in female school-age children of Kazakh (x2 =0.06,P =0.80 ; x2 =1.40,P =0.24).There was no statistically significant difference in the frequencies of TT/Tt + tt genotype and alleles between the overweight/obesity cases and healthy controls of female school-age children of Han (x2 =0.04,P =0.84 ; x2 =0.04,P =0.84),and there was no statistically significant difference in male school-age children of Han(x2 =0.05,P=0.82;x2 =0.18,P=0.67).Conclusions VDR gene(rs731236)polymorphism bears ethnic diffe-rence.The polymorphisms of VDR gene polymorphism rs731236 are not associated with the susceptibility to overweight/obesity in school-age children of Han,while it is associated with the susceptibility to overweight/obesity school-age children in Kazakh,especially in male school-age children.

Objective:To investigate the prognostic factors and pathological characteristics of mixed subtype thyroid cancer (MSTC) .Methods:Data of 41 cases of MSTC, which were confirmed by postoperative pathology, among from 24, 912 cases of thyroid cancer admitted in Mar. 2005 to Aug. 2020 in the First Medical Center of Chinese People’s Liberation Army General Hospital, were retrospectively analyzed. 37 cases underwent surgical treatment, while 4 cases only underwent puncture to confirm the pathology due to physical conditions, and no surgical treatment was performed. The tumor size, number of lesions, capsule invasion, AJCC 8th TNM staging, surgical methods, radiotherapy and chemotherapy were collected. The MSTC patients in the group were followed up to obtain the postoperative situation. SPSS 25.0 and R studio statistical software was used for data processing, and Cox single factor and multivariate regression were used to analyze independent risk factors.Results:In the 41 cases, there were 9 cases of papillary carcinoma (PTC) mixed with follicular carcinoma (FTC) , and 8 cases of mixed medullary and follicular carcinoma (MMFTC) . There were 15 cases of poorly differentiated thyroid cancer (PDTC) , 4 cases of squamous cell carcinoma of thyroid (SCCT) , and 5 cases of undifferentiated thyroid carcinoma (ATC) . The median follow-up time was 18 months, and 11 patients died during the follow-up, with a mortality rate of 26.8%. Average onset age was (51.41+15.69) years. 4 cases had postoperative recurrence during the follow-up, including 2 cases of local recurrence, and 2 cases of distant metastasis. Single factor results showed that age, degree of tumor differentiation, surgical method, radiotherapy and chemotherapy were the risk factors affecting the prognosis of patients with MSTC ( P<0.05) . Multivariate analysis showed that age at diagnosis ( P=0.007) and surgical procedure ( P=0.017) were independent risk factors for prognosis in patients with MSTC. Conclusion:Middle-aged and elderly women are at high risk for MSTC, and the degree of tumor differentiation is proportional to survival. Due to the multi-type and pleomorphic pathological findings, a reasonable treatment plan has good effects on prognosis of MSTC.
