Objective To evaluate the long-term efficacy and safety of endoscopic mucosal resection (EMR) for lesions at gastroesophageal junction (GEJ). Methods A total of 51 lesions located at GEJ from 51 patients, with an average size of 10. 9±4. 0 mm (3-28 mm), were treated with EMR between November 2005 and March 2009, among which 39 were diagnosed as low grade dysplasia and 12 as high grade dysplasia pathologically after EMR. The histopathologic results were compared between biopsies and EMR samples. All patients were followed up endoscopically. Results Complete resection was achieved in 44 ( 86. 3% ). The histopathologic diagnosis of 25 cases (49. 9% ) was inconsistent between biopsy and EMR samples, with 24 exhibited higher grade dysplasia after EMR. Main complication during EMR was bleeding in 17 patients ( 33. 3% ), all of which were successfully managed. No perforation or postoperative stenesis occurred. Endoscopic follow-up was carried out in 8 patients for more than 3 years, in 17 for 2-3 years, in 12 for 1-2 years and in 14 for less than 1 year. No death occurred during follow-up. Conclusion EMR can be adquately adopted as an effective treatment for pre-cuncerous lesions at GEJ, which is important in blocking malignant progression of dysplastic lesions.

Objective This study was to explore deaf people's needs for a smooth communication with doctors and/or nurses during health consultation in the outpatient department or when being hospitalized and supply reference for compilation of sign language textbooks.Methods Purposive sampling was used and semi-structured interviews were conducted.Six deaf participants who met the inclusion and exclusion criteria were interviewed.It lased for 20 to 40 minutes for each interview.Interviews were recorded digitally and then transcribed and validated.Transcripts were analyzed using a method of thematic analysis.Results Three themes were identified,i.e.needs for sign language interpreters,needs for information and knowledge.and needs for psychosocial and emotional support.Needs for sign language interpreters meant that doctors and nurses were able to communicate with them using simple sign language instead of terminology.The required information and knowledge covered three aspects,i.e.health condition,pharmaceutical therapy,and self-care activity.Conclusions There may exist serious communicative barriers for deaf people during their health consultation in the outpatient department or when being hospitalized.There is a need for healthcare professionals who are competent in sign language to establish the health delivery environment with minimal barriers.

Objective This study aimed to explore issues about dysandia female during pregnancy,peripartum and contraception and to supply reference for their reproductive health improvement. Methods Purposive sampling strategy was used. With the aid of an interview guide, 12 dysaudia women who met inclu-sion and exclusion criteria were invited to be interviewed. Interviews were recorded, validated and then ana-lyzed. Results Four themes were generated, limited knowledge, passive information acquisition, total depen-dence on family and reluctant to talk about contraception. Total dependence on family was noticeable during pregnancy and peripartum. Though little was known about health protection related to pregnancy, peripartum and contraception, participants were passive at seeking for relevant information. Conclusions Deaf women may experience more threats to reproductive health in relation to pregnancy, peripartum and contraception that they require more guidance and assistance.

OBJECTIVETo investigate the origin of a rare supernumerary chromosome in a patient with premature ovarian failure (POF), and to explore the relationship between this abnormal karyotype and pathogenesis of POF.

METHODSGTG banding karyotyping, Q-banding and fluorescence in situ hybridization (FISH) were employed for the investigation.

RESULTSThe extra chromosome was identified as i(Y)(q10) by FISH with a panel of sex chromosome probes. The patient's karyotype was described as: 47,XX,+ ish mar i(Y)(q10) (DXZ1-, SRY-, DYZ3+, DYZ1++, wcpY+).

CONCLUSIONCo-occurrence of the supernumerary i(Y)(q10) with a female kryotype is extremely rare. This supernumerary chromosome may cause failure of X chromosomes synapsis during pachytene of meiosis I, which may trigger apoptosis of many oocytes and result in POF of the patient. Q-banding, FISH and multiple probes have been critical for accurate diagnosis of the unknown chromosome.

OBJECTIVETo investigate the prophylactic and therapeutic effect of oxymatrine on experimental liver fibrosis and to reveal its mechanism.

METHODSBy establishing D-galactosamine-induced rat liver fibrosis model, we observed the effect of oxymatrine on serum and tissue biochemical indexes, content of liver hydroxyline, expression of TGF?1 mRNA and changes of tissue pathology.

RESULTSThere was a decline of liver hydroxyline and serum AST and ALT in oxymatrine group compared to those of the D-GalN group. The hydroxyline content in oxymatrine pretreatment group was (0.50 0.11)mug/mg compared with (0.99 0.14)mug/mg in D-GalN group (t=8.366, P<0.01). The content in oxymatrine treatment group was (0.44 0.04)mug/mg compared with 0.70 0.06 in D-GalN group (t=9.839, P<0.01). The SOD activity was (149.81 15.28) NU/mg in oxymatrine pretreatment group and (95.22 16.33) NU/mg in the model group (t=7.309, P<0.01); (157.68 19.54) NU/mg in the treatment group compared with (119.88 14.94) NU/mg in the model group (t=4.348, P<0.01). MDA in the pretreatment group was (2.06 0.17) nmol/mg, lower than (4.57 0.37) nmol/mg in the model group (t=17.529, P<0.01). In the treatment group, it was (1.76 0.24)nmol/mg, lower than (3.10 0.17) nmol/mg in the model group (t=12.697, P<0.01). TGF?1 mRNA reduced in the pretreatment and treatment groups as compared with that in the model group (0.21 0.01 vs 0.50 0.01, t=48.665, P<0.01; 0.18 0.02 vs 0.38 0.01, t=22.464, P<0.01). Electron microscopy showed that oxymatrine group had milder hepatocyte degeneration and less fibrosis accumulation than did the model group. Microscopy revealed wide septa expansion from the portal area to the central venous, piecemeal and confluent necrosis and pseudo-nodular formation in part of the lobular in the model group. While in oxymatrine group these lesions were much improved.

CONCLUSIONSOxymatrine shows prophylactic and therapeutic effect in D-galactosamine induced rat liver fibrosis. This is partly by protecting hepatocyte and suppressing fibrosis accumulation through anti-lipoperoxidation.

The widespread application of next generation sequencing (NGS) in clinical settings has enabled testing, diagnosis, treatment and prevention of genetic diseases. However, many issues have arisen in the meanwhile. One of the most pressing issues is the lack of standards for reporting genetic test results across different service providers. The First Forum on Standards and Specifications for Clinical Genetic Testing was held to address the issue in Shenzhen, China, on October 28, 2017. Participants, including geneticists, clinicians, and representatives of genetic testing service providers, discussed problems of clinical genetic testing services across in China and shared opinions on principles, challenges, and standards for reporting clinical genetic test results. Here we summarize expert opinions presented at the seminar and report the consensus, which will serve as a basis for the development of standards and guidelines for reporting of clinical genetic testing results, in order to promote the standardization and regulation of genetic testing services in China.
