Objective To investigate the relationship between cerebral infarction (CI) and the single-nucleotide polymorphisms (SNPs) of rs11833579G/A and rs4980959C/A of NINJ2 gene in Han population of the Western Guangdong province in China. Methods Genotype and allele frequency of rs11833579G/A and rs4980959C/A were analyzed in 278 cerebral infarction patients and 120 healthy controls. Results There was insignificant difference in frequencies of genotypes and allele in two polymorphisms (rs11833579 G/A and rs4980959C/A) of NINJ2 gene between CI and control groups (P>0.05). AA genotype frequency of rs4980959C/A was more in patients with small-artery occlusion (SAA) than in the control group (18.3% vs 9.2%, P=0.041), while the A allele frequency was more in the patients with SAA than in the control group (35.4% vs 46.1%, P=0.019). Logistic regression analysis indicated that AA genotypes of rs4980959C/A was a risk factor for SAA over G allele carriers (OR=4.012, 95%CI: 1.209~14.939, P=0.027). Conclusion NINJ2 gene 5' upstream untranslated region SNPrs11833579G/ A polymorphism does not associate with the risk of ischemic stroke. NINJ2 gene 5' upstream untranslated region SNPrs4980959C/ AA allele is a risk factor for SAA, AA genotype is a susceptible genotype for SAA.

Objective To investigate the expression of phosphorylated RB (pRB) in the invasion front of papillary thyroid carcinoma and the clinical pathological implications. Methods Immunohistochemistry was ap-plied in analyzing pRB expression feature and the clinical pathological implications in a total of 82 patients who underwent total or subtotal thyroidectomy and neck lymph node dissection for papillary thyroid carcinoma. Results The displacement of pRB proteins from the nucleus to the cytoplasm was observed in the invasive front of papil-lary thyroid carcinoma , which was an independent predictor of lymph node metastasis in papillary thyroid carci-noma. Conclusion Nuclear-cytoplasmic transport of pRB in the invasive front was an independent predictor of lymph node metastasis in papillary thyroid carcinoma.

Objective To explore the association of ubiquitin-specific proteases 24 (USP24) gene polymorphisms with susceptibility to sporadic Parkinson's disease (PD) in the Han Guangdong population. Methods From August, 2006 to January, 2014, single nucleotide poly-morphisms (SNPs) of rs12138592 and rs6671533 in the intron region of USP24 were genotyped in 200 patients with sporadic PD and 200 healthy controls using the SNaPshot technique. Results There was significant difference in the allele and genotype frequency of rs12138592 between the patients and the controls (P<0.01), and no significant difference was found in the allele and genotype frequency of rs6671533 (P>0.05). Conclusion The SNP of rs12138592 in the intron region of USP24 is associated with the susceptibility to sporadic PD in the Han Guangdong population, and the A allele may contribute a protective roles to PD.

Objective To understand the infection of ureaplasma urealyticum in genitourinary of secondary infertility of male and ex-plore the relationship between the genotype of individual ureaplasma species and genitourinary infection of them . Methods Based on the multiple-banded antigen genes (MBA) of ureaplasma urealyticum, 10 pairs of oligonueleotide primers targeting the 5'ends of the MBA genes were designed to identify the MBA genes of U. parvum and U. ureaplasma by PCR-based genotyping system. The 10 pairs of oligonucleotide primers could distinguish the two biovars and 14 serovars of U. ureaplasma. Results A total of 278 (48.6%) positive ureaplasma culture were obtained from 572 patients attending our clinic of reproductive medical eenter. These methods were used to identify and genotype U. ureaplasma in 311 (54.4%) of 572 patients with genitourinary infection among them U. parvum (biovar 1) was detected in 37.1% and U. ureaplasma (biovar 2) in 17.8%. serovar 1 was in 12.4%, serovars3/14 in 17.1% serovar 6 in 7.5%; subtype 1 of biovar 2 was in 5.6%, subtype 2 in 8.9% and subtype 3 in 2.8%, respectively. Conclusion The PCR-based genotyping system will facilitate future stud-ies of relationship between individual Ureaplasma species or subtypes in genitourinary of secondary infertility of male. The methods described here are relatively rapid, practicable, and specific for the detection species identification and subtyping of Ureaplasma species.

Abstract: Objective To research the relationship between promoter polymorphism-438 A/G of thrombin-activatable fibrinolysis inhibitorgene (TAFI-438 A/G) and atherosclerotic cerebral infarction (ACI) in Chinese Han population. Methods TAFI-438A/G genotypes andtheir allele frequencies were identified with the polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) in225 ACI patients and 184 healthy controls. Results There was no significant difference of TAFI-438A/G polymorphism between ACI groupand control group. Stratified by gender, in males, the incidence of A allele was 28.6% in ACI group, and 20.6% in control (P=0.039); of theAA genotype was 9.0% in ACI group, and 1.9% in control (P=0.019). But no significant difference was found in females. ConclusionTAFI-438A/G polymorphism is associated with the risk of ACI in males, that AA genotype may increase the risk of ACI.

Objective This study aimed to conduct a systematic review and meta-analysis of randomized controlled trials(RCTs)assessing the clinical efficacy of acupuncture for chronic stable angina(CSA).Methods PubMed,The Cochrane Library,Embase,CNKI,VIP,WanFang Data,CBM databases,ClinicalTrial.gov and Chinese Clinical Trial Registry were electronically searched to collect randomized controlled trials(RCTs)of acupuncture for CSA and only RCTs that included acupuncture as the sole or combination of acupuncture in the treatment of CSA.The retrieval period was from the establishment of the database to May 19,2022.The primary outcome measure was the frequency of angina attacks,and the secondary outcome measures were angina efficacy,total effective rate of ECG improvement,nitroglycerin use after treatment,patient-perceived overall effectiveness,performance on the Six-Minute Walk Test(6-MWT),depression as measured by the anxiety as measured by the Self-Rating Anxiety Scale(SAS),Self-Rating Depression Scale(SDS),adverse effects.Results Twelve studies with a total of 1605 case subjects were included and grade quality of evidence reviews had 1 outcomes as medium quality evidence,5 outcomes as low quality evidence and 4 outcomes as very low quality evidence.Acupuncture treatment resulted in significantly greater reductions in angina attacks,visual analog scale(VAS),6-minute walk test,angina efficacy,electrocardiogram improvement rate,angina efficacy,total clinical response rate.Conclusion The efficacy of acupuncture combined with western medicine in treating CSA is better than that of Western medicine alone,thanks to restricted by the number and quality of included researchs,higher quality studies are required to prove above conclusions.

Objective To study the safety and efficacy of laparoscopic resection of hemangioma in the right posterior hepatic section without any blood flow occlusion.Methods Patients with hemangiomas in the right posterior section of liver operated from January 2016 to June 2018 in the Affiliated Hospital of Youjiang Medical College for Nationalities were studied retrospectively.There were 19 females and 9 males.The average age was (37.9 ± 6.1).The operation methods,perioperative factors,hospitalization cost and follow-up outcomes were recorded and analyzed.Results 28 patients with hemangiomas were treated with laparoscopic resection of right posterior hepatic section without any blood flow occlusion.An ultrasound scalpel was applied to split the liver in 27 patients,and ultrasound scalpel combined with Ligasure to split the liver in 1 patient.The mean diameter of the hepatic hemangiomas was (6.7 ± 1.3) cm.The intraoperative blood loss was (330.4 ± 139.0) ml and the operation time was (87.4 ±27.9) min.One patient required conversion to open surgery due to rupture and bleeding of the hemangioma.The conversion rate was 3.6% (1/28).The postoperative drainage time was (45.4 ± 18.9) h.The postoperative hospitalization time was (7.5 ± 1.3) d,and the hospitalization cost was (3.1 ± 0.5) ten thousand yuan.No death or serious complications occurred.No reoperation was needed.The follow-up period ranged from 1 to 30 months,and all the patients were well on follow-up.Conclusions Laparoscopic resection of hemangioma in the right posterior hepatic section without any blood flow occlusion was safe and efficacious.This method can be used for hemangiomas in the right posterior section of liver.
