As a wide field of internet industry, the internet medical is sprouting prosperous with many advanta-ges still, namely promoting the medical resources integration and earlier disease prevention, providing more conven-ient health care services, etc. , but there are still many limitations. By analyzing the role of internet in the promotion of medical services, this article focused on the internet limitations. Ultimately, we put forward we should calmly oper-ate internet and make it as the auxiliary tool for medical care services instead of relying too much on it in order to pro-vide a reference and a basis for the prosperous development of internet medical.

Objective To establish the suspension cell line of Atractylodes lancea and to study the effect of two endophytic fungal elicitors on its essential oil production.Methods The essential oil was extracted by using ultrasonic wave after suspension cell was treated with endophytic fungal elicitors.Then,the determination of four compounds(atractylone,hinesol,?-eudesmol,and atractylodin) was carried out by gas chromatography.Results By testing in various conditions,the suspension cell line with a rapid growth rate was established.Its highest biomass(6.95 g/L) was obtained on day 21.?-Eudesmol was the only detection in the control suspension cell,and its highest content(17.469 ?g/g) was also reached on day 21.The effect of crude elicitors of two endophytic fungi(belong to Cunninghamella sp.and Gilmaniella sp.respectively,named AL4 and AL12) on the cell growth and the production of essentia1 oil were investigated.Overall AL4 elicitor got better effect.When suspension cell of 14-day-old cultures was exposed to AL4 elicitor(carbohydrate 20 mg/L medium) for 7 d,the biomass increased 3.31% over the control,and the four compounds(atractylone: 14.715 ?g/g,hinesol: 28.395 ?g/g,?-eudesmol: 38.794 ?g/g,and atractylodin: 8.310 ?g/g) were all detected.Among them,the content of ?-eudesmol reached 2.22 times as much as the control.Conclusion The cell growth and the accumulation of essential oil of A.lancea could also be promoted by adding crude elicitors of the endophytic fungi AL4 and AL12.

As an important part of the hierarchical medical system in China ,urban secondary hospitals play as a pivot between tertiary hospitals and community healthcare centers.By describing the overall development status of such hospitals in China ,the paper discussed the problems existing in the development of urban secondary hospitals and put forward strategies in the hope of providing reference for the transformation of these hospitals .

Medical insurance system plays a key role in China's social security system.In the social insurance system,medical insurance features the widest coverage and the most complex in mechanism,while China' s medical insurance system itself is found with many setbacks.This paper probed into such risks found in the county-level medical insurance system as excessive cost growth causing overpayment of the medical insurance fund and poor supervision of the fund.On such basis,the authors recommended such policy changes as payment reform,and enhanced supervision over the fund,the demand side,and the government,in an effort to optimize China' s medical insurance system for theoretical and decision reference of other county-level hospitals in their reforms.

Objective To investigate the application of fetuses with talipes equinovarus (TE) using chromosomal microarray analysis (CMA) technology. Methods From May 2012 to June 2015, 54 fetuses were found with TE and with or without other structural anomalies by prenatal ultrasound. Karyotyping was taking for them all, and the fetuses with normal karyotypes took another CMA test. The data were analyzed with CHAS software. Finally all the cases were followed up to know about their pregnancy outcomes. Results One of the 54 cases was detected with abnormal karyotype which was trisomy 18 (2%, 1/54). CMA was undertaken to the remaining fetuses, they were divided into 2 groups, including isolated TE group (n=38) and complex TE group (n=15). The detection rate of clinical significant copy number variations (CNV) by CMA was 11% (6/53), while isolated and complex TE group were 5% (2/38) and 4/15, respectively (P=0.047). Of the 53 cases, 51 cases were successfully followed up. Eleven cases were found without TE after birth, and the false positive rate (FPR) of TE was 22%(11/51). Conclusions Whole-genome high-resolution CMA increased the detection rate by 11% in fetuses with TE. With the FPR and the detection rate of the clinical significant CNV of 2 groups, whole-genome CMA could be recommended to the fetuses with complex TE group but normal karyotypes. A series of ultrasonic tests should be suggested to the isolate TE group, while with the abnormal ultrasound, fetuses would be suggested to have CMA test for decreasing the rates of invasive prenatal diagnosis and FPR.

OBJECTIVETo analyze patients with skeletal anomalies (SA) but a normal karyotype using chromosome microarray analysis (CMA).

METHODSFrom June 2012 to May 2015, 43 children found to have skeletal anomalies with or without other abnormalities were subjected to karyotyping analysis. For those with a normal karyotype, DNA was extracted and hybridized with Affymetrix CytoScan 750 kb arrays following the manufacturer's protocol. The results were analyzed with CHAS v2.0 software.

RESULTSTwo patients (4.65%) were detected with an abnormal karyotype. The remaining 41 patients with a normal karyotype were classified into 3 groups: isolated SA (n=17), SA with mental retardation (n=6), and SA with other structural anomalies (n=18). Clinically significant copy number variations (CNVs) were found in 21.95% (9/41) of the cases, which included 17.65% (3/17) with isolated SA, 33.33% (2/6) with SA and mental retardation, and 22.22% (4/18) of SA with other structural deformities.

CONCLUSIONWhole-genome CMA can detect clinically significant CNVs which may not be found by conventional karyotyping analysis and increase the detection rate by approximately 21.95%. It may be recommended for patients with SA but a normal karyotype.

PURPOSE: An older female predominance has been reported among chronic cough patients in Western countries, which is considered to be associated with a higher cough sensitivity in females. However, the characteristics of Chinese chronic cough patients remain unclear. This study aimed to explore the age and sex distribution as well as their relationship with cough reflex sensitivity to capsaicin in Chinese chronic cough patients. METHODS: We analyzed the demographic features of 1,882 consecutive chronic cough patients who attended our cough clinic in Guangzhou, China. Cough sensitivity to capsaicin, which was defined as the lowest concentration of capsaicin causing 5 coughs or more (C5), was measured in 539 of the 1,882 patients and 68 healthy volunteers. RESULTS: The mean age of the patients was 43.0 ± 13.7 years and patients aged <50 years accounted for more than two-thirds of the study population. Around 87% of the patients were never-smokers. The proportion of females (51.5%) was almost equal to that of males (48.5%). The pattern of the age and sex distribution was consistently reflected within most common causes of chronic cough, while a female predominance was shown in patients with cough-variant asthma and patients aged ≥50 years. Female patients had higher cough sensitivity to capsaicin than male patients (log C5: 1.58 ± 0.84 vs. 2.04 ± 0.84 μmol/L, P = 0.001), and patients aged ≥50 years had higher cough sensitivity to capsaicin than patients aged <50 years. CONCLUSIONS: In China, patients with chronic cough have a roughly equal sex distribution and a middle-aged predominance, irrespective of a higher cough sensitivity to capsaicin in females and older patients.

Objective: To investigate the situations of AIDS related knowledge, sexual behavior with various partners among HIV positive patients in Shenzhen before highly active anti-retroviral therapy, and to provide evidences for health education intervention. Methods: Questionnaire survey and information collection were carried out among HIV positive patients, under the informed consent, during the first physical examination before highly active anti-retroviral therapy. Results: The overall awareness rate of AIDS knowledge was 91%, 94.46% and 80.95% respectively for homosexual and heterosexual populations, with significant difference between the two groups (χ²=21.254, P<0.001). In addition, there were significant differences in the factors related to education, income, route of infection, marital status, residence and other related factors (P<0.05). In HIV positive MSM, primary sexual behavior occurred mainly at the age of less than 30 (96.8%) and in university or earlier stage (58.3%), college students as the first sexual partner accounted for 44.9%, and once used Rush accounted for 42.7%. There were significant differences in the number of temporary sexual partners and condom use frequency between homosexual and heterosexual subjects (P<0.05). Conclusions Individuals infected with HIV via different routes are variant on AIDS cognition. Health education on AIDS related knowledge and sexual security before and after antiviral treatment can not only improve the awareness rate of HIV/AIDS infection, but also can reduce the risk of the spread of HIV/AIDS.
