Objective Quantifiably and located measure the methylation rate of 21 cytosinephosphate-guanosine (CpG) sites in the 3' region of L1 gene and long control region (LCR) gene of HPV16 DNA in asymptomatic patients,cervical intraepithelial neoplasia (CIN) patients,and cervical cancer patients.To analysis the relationship between HPV16 methylation and it's pathogenicity.Methods Chosen 30 cases with HPV16 positive in each group.Firstly,extract DNA from the remaining cells of liquid-based cytology specimen and bisulfite treatment DNA,then amplify the 3' region of L1 gene and LCR gene,test the methylation rate of 21 CpG sites of HPV16 DNA in three groups.Results All of the 5 CpG sites in E6/E7 promoter (31,37,43,52,58) were hypomethylation in cervical cancer group (21.86％,28.15％,21.37％,26.15％,15.48％,respectively),hypermethylation in asymptomatic group,and middle-methylation in CIN group,in which there were significant difference among three groups (all P ＜0.01).The CpG site in 7032,7091,7136 of the 3' region of L1 gene was also different methylated among three groups (all P＜0.01).Hypermethylation was found in cancer group (18.89％,27.72％),hypomethylation was found in asymptomatic group (2.71％,6.95％) in 7032 and 7091.In 7136,the highest methylation was detected in CIN (66.45％),the lowest in asymptomatic (34.85％),middle in cancer group (46.43％).Conclusion The methylation status of CpG sites in the 3' region of L1 gene and E6/E7 promoter of HPV16 is significant different among three groups,which is likely to anticipate the pathogenesis of CIN and cervical cancer.

Objective: To investigate the clinical features and survival factors of primary fallopian tube car-cinoma. Methods: We used Kaplan-Meier survival analysis, single factor analysis and multivariate analysis to evaluate the prognostic factors of 40 patients diagnosed with primary fallopian tube cancer. Results: The aver-age age of the patients was 51 years and all of them received surgery. There were 29 (72.5%) stage Ⅰ or Ⅱ patients, 11 stage Ⅲ or Ⅳ patients. Thirty-one (77.5%) patients were diagnosed with poorly differentiated tu-mors and 22 (55%) patients had serous adenocarcinoma. Thirty-seven patients received PAC/PC or TC che-motherapy after surgery. Six patients (15%) had recurrences within 23 to 56 months after surgery. The medi-an survival of Ⅰ～Ⅱ and Ⅲ～Ⅳ stage patients was 79 and 35 months, respectively. The total 5-year survival was 58% and 0 (P=0.005). Univariate and multivariate analysis showed that stage (Ⅰ～Ⅱ vs. Ⅲ-Ⅳ), grade (G_1+G_2 vs. G_3), residual disease after surgery (none, <1cm vs. >1cm) were significant factors affecting surviv-al. In accordance with the formula to calculate the half-life of CA125 and compare preoperative serum CA125 with the value at 3 weeks after surgery (T_(1/2)>3 week, T_(1/2)<3 week), the 5-year survival was 78% and 50%, re-spectively (P=0.036). Conclusion: Special attention should be paid to the joint screening of primary fallopian tube cancer in clinical practice in order to avoid misdiagnosis. The consecutive measurements of serum CA-125 level may have significant value as a prognostic indicator for patient survival.

Sentinel lymph node (SLN) detection in endometrial cancer is still in the exploration stage. But a good many studies have confirmed the feasibility of SLN detection in patients with early endometrial cancer. Higher detection rate of SLN can be achieved by the combination of blue dye and radiocolloid. Compared with intracervical injection, more injections at different sites of the uterine corpus and hysteroscopic injection may improve SLN detection rate and para-aortic SLN detection rate. SLN detection rates are also related to some other factors such as the amount of tracers, the interval between injection and detection, and the depth of myometrium invasion. Serial-step section of SLN combined with immunohistochemistry staining with anti-cyto-keratin may improve the detection of micrometastasis (MM) in SLN. SLN procedure can detect MM which cannot be found by traditional pathological techniques. The ultrastaging will allow better stratification of patients at intermediate risk and can provide valuable informaiton for the selection of adjuvant therapy, thus decreasing the recurrent rate.

Objective To analyze the differences of positive detection rate and copy number of human papillomavirus (HPV) DNA and E6/E7 mRNA between different grades of cervical lesions, and evaluate their clinical values in early screen?ing of cervical cancer. Methods The cervical exfoliated cell samples from 154 women undergoing biopsy examination and 32 objects undergoing hysterectomy (control group) were collected in Tianjin Central Hospital of Gynecology Obstetrics in 2014. According to the pathological results of cervical biopsy, 154 samples were divided into low-grade squamous intraepi?thelial lesion group (LSIL, n=51), high-grade squamous intraepithelial lesion group (HSIL, n=71), and squamous cell carci?noma group (SCC, n=32). HPV DNA was tested with hybrid capture technology, and E6/E7 mRNA was detected with fluores?cence quantitative hybridization. Immunohistochemistry was performed by detecting E6/E7 protein in all patients after sur?gery or cervical biopsy. Results Combined results of HPV DNA and E6/E7 mRNA demonstrated that the positive detection rate was significantly lower in control group than that of all levels of lesion groups (P<0.05). The copy number of high risk HPV E6/E7 mRNA was significantly increased with the aggravation of lesions (P<0.05), whereas no difference was found in that of HPV DNA. Compared with the normal control and low-grade squamous intraepithelial lesion group, cervical cancer patients with mRNA copies > 10 000 E6/E7 were significantly increased in high-grade squamous intraepithelial lesion group. Immunohistochemical results showed that the positive detection rate of E6/E7 was significantly lower in control group than that of all levels of lesion groups (P<0.05). The positive rate of E6/E7 was significantly higher in the high-grade squa?mous intraepithelial lesion group than that of low-grade group (P<0.05). Conclusion HPV infection is closely related to cervical abnormalities, which is one of effective measures for early screening of cervical cancer. The negative result of HPV DNA is very helpful to exclude the cervical abnormality, whereas the positive detection of mRNA has great value in predict?ing the disease. Combined results of positive detection and copy number make a comprehensive evaluation for the risk of cer?vical lesions.

The growth of brain metastasis needs appropriate microenvironment, and the change of normal brain microenvironment is the basis for exploring metastasis with MRI. Through the local magnetic field changes and the application of contrast agents for improving the discrepancy of the cerebral tissue, MR can accurately detect brain metastasis in position, number, size, and shape. MR with contrast-enhanced technique is the first choice for screening brain metastasis. The application of all kinds of new MR techniques, sequences and intracellular contrast agents can not only further improve the specificity of detection, but also improve the sensitivity of MRI, which is favorable to formulating reasonable treatment and prolonging the lifetime of the patients. The microenvironment of brain metastasis and advances in the new MR techniques were reviewed in this article.

The current study suggested that gastrointestinal motility has a close relationship with ascending-descending theory of spleen and stomach of TCM.Gastrointestinal symptoms caused by Qi disorder of spleen are identical with the clinical manifestations of gastrointestinal motility disorders.Although spleen and stomach act as the pivot of Qi transporting in the body,the dysfunction of liver,lung,kidney,and heart may also cause disorders of Qi in ascending and descending,manifested as pathological gastrointestinal motility.Therefore,when gastrointestinal motility appears abnormality,we should pay attention to other organs besides analyzing dysfunction of spleen and stomach

Objective To investigate the cytidylyl phosphate guanosine(CpG) islands methylation status of E-cadherin (E-cad) promoter region in human ovarian carcinoma cell lines (ES-2,3 AO, SKOV3 ), and the effect of 5-azacytidine-2 '-deoxycytidines (5-Aza-CdR ) on the cell proliferative ability, invasion and the expression of E-cad protein. Methods Methylation specific PCR(MSP) was used to detect CpG islands methylation status of E-cad promoter region in ES-2,3AO and SKOV3 cell lines. After treated with different concentrations of 5-Aza-CdR, morphological changes of cell lines were observed under microscope. The proliferative ability was evaluated by methyl thiazolyl tetrazolium(MTT) assay. E-cad protein expression was detected by western-blot and cellular invasion was investigated by 24-well matrigel invasion chambers. Results Hypermethylatian status of CpG islands of E-cad promoter region was observed in ES-2 and SKOV3 cell lines, but not in 3AO cell lines. After treated with 5-Aza-CdR (0.1,1.0,10.0 μmol/L), ES-2 and SKOV3 cell lines displayed morphological evidence of differentiation. 5-Aza-CdR was found to decrease proliferation as evidenced by cell growth curve , to increase the level of E-cad protein expression (P ＜ 0.01 ), and effectively inhibit the ability of cell invasion(P ＜0.01 ). Conclusions CpG hypermethylation is an important mechanism of E-cad gene inactivation in ES-2 and SKOV3 cell lines. 5-Aza-CdR be found to inhibit proliferation and invasion, and increase the expression of E-cad probably by the inhibition of hypermethylation.

Objective:To investigate the clinical efficacy of radial extracorporeal shockwave therapy(ESWT)for scapulohumeral periarthritis in the elderly.Methods:A total of 82 patients diagnosed with scapulohumeral periarthritis at the rehabilitation medicine department of our hospital from July 2016 to January 2019 were retrospectively analyzed.The visual analogue score(VAS), Constant-Murley score(CMS), range of motion(ROM), adverse reactions, curative effectiveness and survival analysis were examined before treatment and at several time points within 6 months of treatment.Results:Compared with pre-treatment, the VAS, CMS, ROM, curative effects and survival analysis of patients with primary and secondary scapulohumeral periarthritis improved after treatment in both the conventional rehabilitation therapy group and the conventional rehabilitation therapy combined with ESWT group(all P<0.05). The short-term effects(2 weeks and 1 month after treatment)were better in the conventional rehabilitation therapy combined with ESWT group than in the conventional rehabilitation therapy group( P<0.05). There was no significant difference in long-term effects(2, 4 and 6 months after treatment)between the two groups( P>0.05). For patients with primary scapulohumeral periarthritis, conventional rehabilitation therapy combined with ESWT had advantages over conventional rehabilitation therapy in reducing the VAS score and improving shoulder function(CMS score and ROM)( P<0.05). For patients with secondary scapulohumeral periarthritis, conventional rehabilitation therapy combined with ESWT was better in reducing VAS than conventional rehabilitation therapy( P<0.05), while there was no significant difference in shoulder function improvement between the two groups(all P>0.05). Conclusions:Conventional rehabilitation combined with ESWT can relieve shoulder pain, improve range of motion and has a good safety profile in the treatment of scapulohumeral periarthritis in the elderly, but there is no significant difference in long-term efficacy between conventional rehabilitation therapy and conventional rehabilitation therapy combined with ESWT.

Objective:To observe the changes of choriocapillary blood flow area (CBFA) and diameter of ellipsoid zone absence (DEZA) of eyes with idiopathic macular hole (IMH) before and after surgery and its correlation with visual function.Methods:A prospective study. From May 2019 to January 2020, 23 IMH patients (IMH group and fellow eyes group) diagnosed in the Department of Opthalmology of The First Affiliated Hospital of Bengbu Medical College, and 30 age and gender-matched normal controls (30 eyes, control group) were included in this study. All patients were examined the best corrected visual acuity (BCVA) before and after surgery. The BCVA examination was performed using the international standard Snellen visual acuity chart, which was converted into logarithm of the minimum angle of resolution (logMAR) BCVA for record. CBFA and DEZA were obtained by optical coherence tomography angiography (OCTA). CBFA was measured on the choriocapillary with a circle of 1.0 mm radius centered in the fovea. DEZA was the diameter of ellipsoid zone absence horizontally. The differences of CBFA and logMAR BCVA in the three groups, and the changes of CBFA, DEZA, logMAR BCVA in IMH group before and after surgery were analyzed. The measurement data between the three groups were compared by one-way analysis of variance, and the independent samples t test was used for the comparison between the two groups. Pearson correlation analysis was used for the correlation between the index, multiple linear regression analysis were performed between postoperative visual acuity and preoperative parameters. Results:Before and 6 months after surgery, the logMAR BCVA in IMH group were 1.26±0.7 and 0.48±0.22, CBFA were 1.49±0.30 and 1.92±0.17 mm 2, DEZA were 1 080.22±576.98 and 433.78±423.04 μm, respectively. Compared with those before surgery, BCVA and CBFA were significantly improved, DEZA obviously decreased and the differences were statistically significant ( t=5.53, 7.77, 6.58; P<0.01). CBFA in IMH group was lower than fellow eyes group and control group, the difference was statistically significant ( F=14.13, P<0.01). After surgery, CBFA in IMH group increased similar to that of fellow eyes group ( t=4.32, P=0.37), but lower than that of control group with the significant difference ( t=4.07, P<0.01). The results of Pearson correlation analysis showed that logMAR BCVA and DEZA were positively correlated ( r=0.69, 0.75; P<0.01), CBFA and DEZA were negatively correlated ( r= -0.49, -0.89; P<0.05) before and after surgery. Multivariate linear regression analysis showed that the postoperative logMAR BCVA was positively correlated with DEZA ( t=2.32, P=0.02). Conclusions:After surgery, BCVA and CBFA of IMH eyes are significantly increased, DEZA is obviously reduced. Before and after surgery, logMAR BCVA is positively correlated with DEZA, and CBFA is negatively correlated with DEZA.
