Objective To investigate the clinical characteristics of postmenopausal patients with cervical intraepithelial neoplasia ( CIN) gradeⅡ/Ⅲand cervical cancer . Methods A retrospective analysis was made on the clinical characteristics of 57 cases of postmenopausal patients who were diagnosed as CIN grade Ⅱor above from January 2014 to September 2015.Their age ranged from 49 to 77 (58.2 ±5.6) years old, and the time of menopause ranged from 1 to 36 (9.4 ±6.9) years. Results ①In postmenopausal women with CIN Ⅱ/Ⅲ and cervical cancer, only about 1/5 (11/57, 19.3%) had clinical complaints, and nearly 2/3 (36/57, 63.2%) had smooth cervical appearance .②There were 36 cases of high-risk human papillomavirus ( HPV) (36/39, 92.3%), 20 cases of single HPV16 infection (20/36, 55.6%), 7 cases of HPV16 type and other high-risk HPV infection (7/36, 19.4%), and 9 cases of other types of high-risk HPV infection (9/36, 25.0%).③The positive rate of high-risk HPV was 92.3%(36/39) and the HPV16 positive rate was 69.2% (27/39).TCT examination showed a positive rate of high grade squamous intraepithelial lesion (HSIL) of only 29.6% (16/54), with significant difference (χ2 =6.686 and 14.286, P =0.010 and 0.000, respectively). Conclusions Postmenopausal women with cervical lesions usually have no obvious clinical symptoms . Gynecological examination alone is difficult to judge whether the cervical lesions exist .Strict cervical lesions screening is particularly important .

Objective To study and evaluate the consistency and diagnostic value of electrogastrogram(EGG) and gastroscopy in children′s gastrosis diagnosis.Methods A total of 136 children were checked with gastroscopy and EGG during the same period,then compared the diagnostic accordance rate with 2 ways,and analyzed the characteristics of EGG.Results EGG showed certain characteristics in different gastrosis.Diagnosis of EGG in the group of functional illness was consistence with gastroscopy at 95.8%;others were less than 40%.Conclusion EGG can be used as a method of special value to diagnose children′s functional gastrosis and a screening means in general gastrosis.

Cervical cancer poses a major threat to public health worldwide, early diagnosis of cervical cancer can improve the survival rate of patients. The detection rate of the existing cervical cancer screening methods is not very stable, and there is no reliable non-invasive index to predict the recurrence, metastasis and prognosis of cervical cancer. We searched literaruture for cervical cancer-related diagnostic and prognostic indicators and included 20 related literature, confirming that liquid biopsy is expected to replace and supplement the existing methods of screening and testing. Circulating nucleotides are an important part of liquid bioassays, including circulating cell-free DNA (cfDNA) and circulating cell-free RNA (cfRNA), among which cfRNA is a potentially rich source of tumor biomarkers, especially in the early diagnosis of cervical cancer. It has unique specificity and great potential value in the early diagnosis.

Put forward opinions and suggestions about characteristics of the new era of medical disputes pre -vention treatment through the analysis of a hospital in the past five years occurred in 44 medical disputes .We must fo-cus on innovation and long -term mechanism to prevent medical malpractice , medical malpractice to further improve the prevention, comprehensive mechanism , and continuously improve the effectiveness of medical dispute processing services.

Objective To develop the Chinese version of multidimensional measure for recurrent ab-dominal pain scale(MM-RAP) and test the reliability and validity of it. Methods The Chinese version of MM-RAP was translated and revised and 100 children with recurrent abdominal pain and their parents were surveyed by it. Then the reliability and validity of the scale was tested. Results The teat-retest reliability coefficient of MM-RAP was 0.86. The total Cronbach's coefficient α of the scale was 0.80. Cronbach's coef-ficient α of each dimensions was above 0.70. The results of correlation analysis showed that there was higher correlation between items and its belonged dimensions than that with other dimensions. The results of confir-matory factor analysis indicated the factor structure was similar with the theoretical construction of the in-strument. Conclusions The Chinese version of MM-RAP demonstrated good reliability and validity and was an effective assessment instrument for measuring recurrent abdominal pain of Chinese children.

Objective To establish practical cell model of HCV infection, and investigate the susceptibility of a human liver cell line HepG2 to hepatitis C virus in vitro. Methods A human liver cell line HepG2 was incubated with serum from a chronic hepatitis C patient for 6～8 hours. Both the plus and minus strands of HCV RNA in infected cells or supernatant were examined by reverse transcription polymerase chain reaction (RT PCR). The HCV NS 3,NS 5 antigens in infected cells were respectively detected with the monoclonal antibodies to antigens of their own by immunohistochemical assay. The minus strand of HCV RNA in infected cells were localized by in situ hybridization. Results The intracellular plus or minus stands of HCV RNA were first detected on day 3 post incubation and then could be intermittently detected until day 35 post incubation in cells or supernatant. The positive signals of NS 3,NS 5 antigens could be expressed within cytoplasm of infected cells. The minus strand of HCV RNA was located within cytoplasm by in situ hybridization. Conclustions These results show that a human liver cell line HepG2 is not only susceptible to HCV but also able to support its long time replication in vitro.

Objective To study HP infection and expression of COX-2 in gastric cancer and gastritis in order to investigate the change of COX-2 in the development of gastric cancer and the role of HP infection in the expression of COX-2.Methods A total of 180 biopsy samples from December 2004 to April 2005 were collected.We use immunohistochemistry technology to study HP infection and expression of COX-2 in gastric cancer and gastritis.Results The level of COX-2 expression in gastric cancer and atrophic gastritis complicated with dysplasia was significantly higher than in superficial gastritis(P

Objective To investigate visceral perception and gallbladder contraction function in IBS patients.Methods A total of 76 cases were selected in the First Affiliated Hospital of China Medical University which were diagnosed as IBS cases.They were divided into 2 groups(40 and 36)according to the presence of abdominal pain;they were also divided into 3 groups according to symptomatic types,18 in diarrhea group,30 in constipation and 28 in alternative diarrhea and constipation.The control group included 30 healthy volunteers.Measure the first sensation thresholds and the urge sensation of rectum water pocket volume.Use real-time supersonic image to measure the gallbladder volume before and after meal.Results Compared with normal groups,the first sensation thresholds of diarrhea-predominant IBS group was(33.00?2.02)mL vs(56.00?4.04)mL,and the urge sensation was(86.00?4.53)mL vs(135.00?3.55)mL,P

Serum levels of leptin, insulin like growth factor (IGF)Ⅰ, IGF binding protein 1(IGFBP1), fasting insulin (FINS) were determined in 36 patients with polycystic ovary syndrome (PCOS) and 26 control subjects. The results showed that serum leptin, IGF Ⅰ, FINS in PCOS patients were significantly higher than those in control subjects, and serum IGFBP1 level was significantly lower than that in control subjects. Serum leptin was positively correlated with FINS in PCOS patients.
