AIM:To analyze circulating miR-141 in the serum as a non-invasive biomarker in the patients with prostate cancer ( PCa) and benign prostate hyperplasia ( BPH) , and healthy individuals.METHODS: A total of 75 pa-tients with PCa, 52 with BPH and 40 healthy individuals were enrolled into this study.Total RNA was isolated from the se-rum samples and the circulating levels of miR-141 were determined using quantitative real-time polymerase chain reaction. RESULTS:The serum levels of miR-141 were significantly higher in the patients with PCa compared to the patients with BPH and the healthy controls (P<0.01).The level of miR-141 in PCa group obviously differed from that in BPH group and healthy control group with high diagnosis performance, with areas under the curve of 0.785 and 0.801, respectively. No statistically significant difference of the serum miR-141 levels between the patients with BPH and healthy individuals was observed (P>0.05).The serum miR-141 level was also found to be related to Gleason score, clinical stage and bone me-tastasis status of the patients with PCa (P<0.05), and the patients with higher Gleason scores had higher serum miR-141 levels.No relationship was detected between miRNA-141 level and the patient’ s age, biochemistry recurrence and serum prostate-specific antigen level (P>0.05 for all comparisons).CONCLUSION: Circulating miR-141 could serve as a non-invasive biomarker for prostate cancer diagnosis, staging and prognosis prediction.

Objective To investigate the association of polymorphisms of arylhydrocarbon receptor (AhR) - 1661G/A with glutathione S-transferase pi ( GSTP1 ) - 313A/G and the susceptibility to endometriosis in southern Han Chinese.Methods Total of 432 endometriosis patients undergoing laparoscopic or laparotomy surgery matched with 493 patients with fallopian tube ligation,tubal recanalization,laparoscopic hydrotubation,benign ovarian tumor and teratoma surgeries without endometriosis as control group were enrolled in this study.The single nucleotide polymorphism (SNP) of AhR -1661G/A and GSTP1 -313A/G were detected by using a fluorescent quantitative PCR-based high resolution melting (HRM).Results The numbers of combined genotypes AhR - 1661G/A and GSTP1 -313A/G were 120 patients with AG + AA,64 patients with AG + AG,8 patients with AG + GG,109 patients with GG +AA,84 patients with GG + AG,4 patients with GG + GG,31 patients with AA + AA,10 patients with AA + AG,1 patient with AA + GG at endometriosis group and 131 patients with AG + AA,68 patients with AG + AG,6 patients with AG + GG,157 patients with GG + AA,66 patients with GG + AG,4 patients with GG + GG,35 patients with AA + AA,20 patients with AA + AG,3 patients with AA + GG at endometriosis group.There was no statistically different frequencies of genotypes between endometriosis group and control group (x2 = 12.558,P = 0.128 ).Compared with genotype GG + AA,the risk of endometriosis with genotype GG + AG was increased 1.833 time (95％CI:1.233-2.274).Conclusion The combined genotype GG + AG [ from AhR - 1661G/A (GG) and GSTP1 - 313A/G (AG) ] might be related with susceptibility to endometriosis.

Positive linear correlation was found between TSH level and detection rate of congenital hypothyroidism (CH). When measured with a cut-off point at 9, 10, 15 and 20 mU/L of TSH, the sensitivity of positive detection rate for CH was 99.77%, 96.80%, 81.25% and 71.88%, respectively. TSH > 9 mU/L seems to be a reasonable cut-off value.

Objective To investigate the association of tumor necrosis factor-alpha (TNF-α) gene promoter region - 1031T/C and its combination with interleukin-6 (IL-6 ) gene promoter region -634C/G single nucleotide polymorphisms (SNP) with the genetic susceptibility to endometriosis.Methods Total of 432 endometriosis patients and 499 non-endometriosis women who had received an operation due to tubal ligation,tubal recanalization,laparoscopic hydrotubation,ovarian simple cyst and teratoma were collected and separated into endometriosis group and control group,that all cases were confirmed by operation and pathology.A case-control study was performed in endometriosis and control group to evaluate the association of these SNP with the susceptibility to endometriosis by using a fluorescent quantitative PCR-based high resolution melting ( HRM ) method.Results ( 1 ) TNF-α - 1031T/C genotype:the T and C of TNF-α - 1031T/C allele frequencies in the endometriosis group and control group were 79.2％ (684/864),20.8％ (180/864) and 81.8％ (816/998),18.2％ (182/998),respectively.The TT,TC and CC of TNF-α - 1031T/C genotype frequencies in the two groups were 63.7％ (275/432),31.0％ ( 134/432 ),5.3％ (23/432) and 66.5％ (332/499),30.5％ (152/499),3.0％ ( 15/499),respectively.There were no statistical significances in the TNF-α - 1031T/C alleles and genotypes distributions between the two groups ( P =0.158,P =0.186 ).( 2 ) TNF-α - 1031T/C and IL-6 - 634C/G conjoint genotypes:to research on the TNF-α - 1031T/C and IL-6 -634C/G genotypes for conjoint analysis,the TT + CC,TC + CC,CC +CC,TT + CG,TC + CG,CC + CG,TT + GG,TC + GG and CC + GG combination genotype frequencies in the two groups were 39.4％ ( 170/432 ),19.4％ ( 84/432 ),4.6％ ( 20/432 ),20.6％ ( 89/432 ),8.8％ (38/432),0.9％ (4/432),3.5％ (15/432),2.3％ (10/432),0.5％ (2/432) and 36.7％ ( 183/499),17.4％(87/499),1.4％ (7/499),26.1％ (130/499),10.4％ (52/499),1.2％ (6/499),3.8％ (19/499),2.6％ ( 13/499),0.4％ (2/499),respectively.There were no statistical significances in the combination genotypes distributions between the two groups ( P =0.107 ).As compared with carriers of TT + CC combination genotype,the endometriosis risk of carriers of CC + CC combination genotype enhanced 3.076 times ( 95％ CI:1.268 - 7.457,P =0.009 ),and the endometriosis risk of carriers of other combination genotypes were no statistical significances (all P ＞ 0.05 ).ConclusionsThe study demonstrates that there are no significant association between the SNP of TNF-α - 1031T/C and genetic susceptibility to endometriosis.However the results indicate that there are significant association betweengenetic susceptibility to endometriosis and the combination polymorphisms of TNF-α -1031T/C and IL-6- 634C/G.

Objective To investigate the association of PR gene exon 5 region H770H (rs1042839) single nucleotide polymorphism (SNP) with the genetic susceptibility to endometriosis (EM) in southern Han Chinese women. Methods Totally 431 EM patients and 499 non-EM women were collected and separated into EM group and control group, that all cases were confirmed by operation and pathology. A case-control study was performed in EM and control groups to evaluate the association of these SNP with the susceptibility to EM by using a fluorescent quantitative PCR-based high resolution melting (HRM) method. Results The C and T of PR H770H allele frequencies among the EM and control groups were 97.9%(844/862), 2.1% (18/862) and 99.4% (992/998), 0.6% (6/998), respectively. The CC, CT and TT of PR H770H genotype frequencies among the EM and control groups were 95.8%(413/431), 4.2%(18/431), 0 and 98.8%(493/499), 1.2%(6/499), 0, respectively. There were statistical significances in the PR H770H alleles and genotypes distributions between the two groups (χ2=7.386, P=0.007;χ2=8.135, P=0.004). Carrying allele C reduced the risk of EM (OR=0.986, 95%CI: 0.976-0.996), while carrying allele T enhanced the risk of EM (OR=3.319, 95%CI: 1.323-8.325); carrying genotype CC reduced the risk of EM 0.970 time (OR=0.970, 95%CI: 0.949-0.991), whereas carrying genotype CT enhanced the risk of EM 3.473 times (OR=3.473, 95%CI:1.391-8.671). Conclusion There is significant association between the polymorphism of PR H770H and genetic susceptibility to EM in southern Han Chinese women.

In conventional ear implantation surgery, clinical physicians usually make a surgery planning based on their observation on series of 2D X-ray images or CT images. Such a planning method requires the physicians to have a high level of clinical experience. Besides, the whole operation is unintuitive, and might have certain risk. Considering these facts, we have developed a computer-aided system for the surgery planning of the implantation of artificial ear based on CT imaging and 3D reconstruction techniques. The system effectively overcomes the main drawbacks in conventional surgery planning techniques, and it makes the surgery planning procedure more precise, safe, and intuitive.

Objective:To summarize and analyze the clinical characteristics, treatment and prognosis of superior vena cava syndrome (SVCS) with malignant tumors in children, and to improve the understanding of its clinical management.Methods:Clinical data of 50 children with SVCS combined with malignant tumors treated in the First Affiliated Hospital of Zhengzhou University from November 2010 to May 2022 were analyzed retrospectively.The pathological types, clinical manifestations, imaging examination, treatment and prognosis were summarized.The overall survival (OS) rate and event-free survival (EFS) rate were evaluated by Kaplan-Meier method.Results:Among the 50 cases, 38 were males and 12 were females, with a male/female ratio of 3.2∶1.0.The median onset was 12.5 (8.0, 14.5) years, and the most common onset occurred in adolescence (66.0%, 33/50). Cough (80.0%, 40/50) was the most common clinical manifestation, followed by face and neck edema (66.0%, 33/50), chest tightness (56.0%, 28/50) and dyspnea (50.0%, 25/50). All the 50 cases were confirmed by histopathological examination, 39 cases(78.0%) were diagnosed as non-Hodgkin′s lymphoma (NHL). NHL was the most common malignant tumor, of which T-lymphoblastic lymphoma (T-LBL) accounted for 74.4%(29/39). All the 50 cases were examined by CT examination, involving 42 cases (84.0%) detected with mediastinal masses.Pleural effusion (86.0%, 43/50) and pericardial effusion (70.0%, 35/50) were common imaging findings.The 3-year OS rate and EFS rate of them were 59.7% and 57.9%, respectively.The 3-year OS rate and EFS rate of the 39 children with NHL were 62.9% and 60.9%, respectively.Conclusions:Children with malignant tumors complicated with SVCS are featured by the acute onset, rapid progress and poor prognosis.NHL is the most common cause, especially T-LBL.Cough, edema of face and neck, chest tightness and dyspnea are common clinical manifestations.Early detection and treatment contribute to save children′s lives.
