ObjectiveTo evaluate the applicable value of attitude control system combined with attitude controllable intelligent capsule endoscope for stomach examination.MethodsA total of 15 patients were recruited to the study.Manipulability of movement and posture change of capsule endoscope,diagnostic efficacy for such locations as gastric cavity,bulb and descending duodenum,image quality and patients'compliance were assessed.ResultsThe procedure was completed in 14 patients.One failed due to downfall of the endoscope to duodenum within 5 min. Mean operation time was ( 23.7 ± 6.5 ) min ( from 5 to 30 min).Ten cases of superficial gastritis,one case of superficial gastritis with bile regurgitation and 1 case of ulceration of the duodenal bulb were diagnosed.No abnormalities were found in 3 others.Endoscopic images were of high quality and only a few were influenced by gastrointestinal peristalsis.All patients showed compliance with no discomfort.Capsule endoscopes were discharged within 2 or 3 days.ConclusionAttitude control system combined with attitude controllable intelligent capsule endoscope in stomach examination is feasible and valuable in clinic.

Objective To investigate the expression of miRNA-16 in peripheral blood monouclear cells (PBMC)from systemic lupus erythematosus( SLE)patients. Methods Sixteen SLE patients who meet the diagnostic criteria of SLE revised in 1997 American rheumatology and 12 healthy individuals were selected as our subjects. Their peripheral blood were sampled. Total RNAs were extracted and purified. The level of miRNA-16 was determined by quantitative reverse transcription PCR( qRT-PCR). U6 was used as housekeeping control. The amount of target miRNA was normalized relative to the amount of U6(ΔCt =ΔCt miRNA-ΔCtU6 ). Relative expression levels were expressed as 2-ΔCt . Results The expression level of miRNA-16 in the SLE patients was 919. 87 ± 715. 45,significantly higher than that in the healthy control group(413. 6 3 ± 330. 69;t= -2. 497,P﹤0. 05). And miRNA-16 expression in SLE active group was 1 298. 79 ± 803. 79,significantly higher than that in SLE stable group(540. 95 ± 350. 15;t= -2. 445,P﹤0. 05). The level of miRNA-16 was related with AnuA (r=0. 669,P=0. 005),ESR(r=0. 608,P=0. 012)and SLEDAI(r=0. 530,P=0. 035). Conclusion The expression of miRNA-16 is high in SLE patients and it is related with SLE activity.

In recent years, osteoporosis (OP) has become one of the main diseases affecting the health of middle-aged and elderly people in China, and the prevalence of OP has increased significantly. The clinical diagnosis and treatment guidelines for this disease are also constantly updated. The overall principles speciallyemphasise that doctors and patients need to work together to negotiate the details of the diagnosis and treatment guidelines, in order to improve the OP clinical diagnosis and treatment rate. Therefore, patients′ knowledge of the disease, understanding of clinical guidelines, and cooperation with doctors to implement diagnosis and treatment plans are very important. In this study, from the most concerned issues of the patients, we established the OP patient practice guideline working group. 14 recommendations, as the OP patient practice guidelines, are proposed in accordance with the relevant principles of the "World Health Organization guidelines development manual" and the international normative process.

OBJECTIVETo identify clinical characteristics of hospitalized laboratory-confirmed influenza cases of children under 15 years old, and their risk factors of influenza infection.

METHODSAnalyzing the reports of hospitalized laboratory-confirmed influenza cases of children under 15 years old who were detected by the sentinel surveillance systems in 10 provinces from December 2009 to June 2014. Such data as their demographic, medical history, clinical symptoms and signs, treatment and outcome were collected using questionnaires, with their clinical characteristics and their risk factors of influenza infection described.

RESULTSOf the 2 937 severe acute respiratory infection inpatients, 190 (6.5%) were laboratory-confirmed influenza cases. 123 (64.7%) of such confirmed cases were male, and 139 (73.2%) were children under 5 years old, with age median of 3.0 years (IQR: 1.0-5.0 years). 20 (10.5%) of them had at least one chronic medical condition, mostly chronic cardiovascular disease (3.2%), immunosuppressive disease (3.2%), and cancer/tumor (2.6%). Most common clinical symptoms of the cases were fever (92.6%) and cough (88.8%), of which abnormal pulmonary auscultation (51.1%) and abnormal chest X-ray performance (36.1%) were the most common clinical signs. 29 cases (15.8%) had complications, of which pneumonia (15.3%) was most common. 16 cases (8.6%) used antiviral drugs, and 4 cases (2.2%) were admitted into ICU. Risk factor analysis suggested that age < 6 months (OR = 0.406, 95% CI: 0.203-0.815) was a protective factor against influenza infection; and age 5-9 years old (OR = 2.535, 95% CI: 1.059-6.066) was a risk factor for influenza infection.

CONCLUSIONHospitalized laboratory-confirmed influenza cases were found mostly in children under 5 years old. Risk exposure for influenza infection varied among age groups.
