OBJECTIVETo survey the married couples at reproductive age for contraceptive knowledge in 5 Chinese cities.

METHODSThe data derived from a questionnaire-based research conducted in 2002 on family planning among married couples in 5 Chinese cities were statistically analyzed.

RESULTSThe total rate of good contraceptive knowledge was 70.10% in the couples. Among all the contraceptive measures, condom use was the most familiar one. The understanding of contraceptive knowledge in couples working in official departments and educational institutes was better than that among the couples working in common enterprises, affected by such factors as gender, geographic regions, educational background and willingness of child-bearing.

CONCLUSIONThe married couples in the Chinese cities have generally good understanding of contraceptive knowledge, which can be affected by different factors among different populations.

Abstract: Objective To follow up and evaluate the stability testing status of γ stereotactic radiotherapy system (hereinafter γ knife WS 582-2017 Specifications for Testing of Quality Control in X and γ referred to ) in medical institutions based on the RayStereotactic Radiotherapy System WS 582-2017 Methods (hereinafter referred to ). A total of 43 medical institutions using γ knife and 54 medical physics personnel were recruited as the research subjects by random sampling method. Based on the - - standard tracking evaluation method, we followed up the evaluation of γ knife stability testing based on WS 582 2017. Results - Only 66.7% of the 54 subjects preformed WS 582 2017 in their daily work. Only 30.2% (all were tertiary hospital) of 43 medical institutions were equipped with complete quality control and testing equipment. The implementation rate of γ knife stability test was 67.4%, and it was not carried out in strict accordance with the test events and test cycle requirements - specified in the WS 582 2017. There were incomplete test events, incomplete records or test cycles that did not meet the Conclusion standard requirements in γ knife stability test. Medical institutions did not carry out γ knife stability tests in strict - accordance with the projects and cycle required by the WS 582 2017. The reasons are related to medical institutions are not equipped with complete testing equipment, the personnel are lack of understanding of relevant national standards, the poor publicity and implementation of the standards, the lack of standardized training channels and inadequate health supervision.

Objective To study the clinical features and prevention means of the infection caused by the highly dathogenic avian influenza A(H_5N_1).Method The clinical data which were confirmed to be an H_5N_1 infected case were analyzed retrospectively.Results The patient,16-year-old male,had no unambi guous history of direct contact with diseased or dead poultry before the onset of the disease.After the onset of the disease,chest X-ray showed flake shadow of the right lower lung quickly spread to the whole lung,associated with mediastinum,subcutaneous emphysema,acute respiratory distress syndrome(ARDS)was occurred on the fifth day.Mechanical ventilation is the primary measure in the comprehensive treatment.On the sixth day,Chinese Center for Disease Control and Prevention detected the pharyngeal specimen of the patient by RT - PCR,Real- time PCR method and suggested positive for the A/H5/N1 virus nucleic acid andis01ated the avian flu(H_5N_1) virus.The disease course was 10 days from onset of illness to death.Conclusions Human infection by the highly pathogenic avian influenza A(H_5N_1)is a deadly infectious disease.If the lesions is widespread and associated with ARDS,prognosis is poor.

OBJECTIVESTo identify serum biomarkers associated with early gastric cancer.

METHODSSerum proteins or peptides were purified with weak cation exchange magnetic beads in 433 patients with gastric cancer and 120 healthy subjects. Distinct peaks were selected using Biomarker Wizard software. The area under receiver operating characteristic curve(AUC) was generated to analyze discrimination capability of peaks between gastric cancers and health people.

RESULTSThirteen distinct peaks were identified between 42 gastric cancer and 42 health people matched by age and gender(P<0.001). There were 5 peaks (2745, 2768, 6629, 3402, and 6436 m/z) with AUC greater than 0.8. Peak of 6629 m/z was identified to be transthyretin. The sensitivity and specificity of 6629 m/z were 65.5% and 92.0%. The sensitivity of 6629 m/z was 59.4% in I(A gastric cancer.

CONCLUSIONTransthyretin precursor may be of value in the early diagnosis of gastric cancer.
