In order to provide a reference and theoretical guidance of the evaluation of electronic medical record (EMR) and establishment of evaluation system in China, we applied a bibliometric analysis to assess the application of methodologies used at home and abroad, as well as to summarize the advantages and disadvantages of them. We systematically searched international medical databases of Ovid-MEDLINE, EBSCOhost, EI, EMBASE, PubMed, IEEE, and China's medical databases of CBM and CNKI between Jan. 1997 and Dec. 2012. We also reviewed the reference lists of articles for relevant articles. We selected some qualified papers according to the pre-established inclusion and exclusion criteria, and did information extraction and analysis to the papers. Eventually, 1 736 papers were obtained from online database and other 16 articles from manual retrieval. Thirty-five articles met the inclusion and exclusion criteria and were retrieved and assessed. In the evaluation of EMR, US counted for 54.28% in the leading place, and Canada and Japan stood side by side and ranked second with 8.58%, respectively. For the application of evaluation methodology, Information System Success Model, Technology Acceptance Model (TAM), Innovation Diffusion Model and Cost-Benefit Access Model were widely applied with 25%, 20%, 12.5% and 10%, respectively. In this paper, we summarize our study on the application of methodologies of EMR evaluation, which can provide a reference to EMR evaluation in China.

Utilized Sucrose as carbon source for fermentation production of pullulan, the yield were 60%. But when Starch-hydrolyzate as an alternative of sucrose as carbon source, the yield were less than 45%. utilize some carbon sources containing fructose, the yield tend upwards. We utilized isostarch-hydrolyzate as only carbon source and got an yield as similar as that sucrose did.

Objective To investigate the effects of a novel synthetic immunostimulator CH2b containing thiazolidin-4-one on the function of invariant nature killer T (iNKT) cells isolated from patients with active rheumatoid arthritis (RA).Methods Peripheral blood mononuclear cells (PBMCs) isolated from patients with active RA were in vitro cultured with α-Galcer and IL-2.The iNKT cells were separated by using magnetic activated cell sorting (MACS) method.The effects of CH2b on the proliferation of iNKT cells were analyzed by using MTT assay.MILLIPLEX MAP Human Cytokine/Chemokine kit was used to measure the levels of IFN-γ and IL-4 in the supernatants of iNKT cell culture.The expressions of IFN-γand IL-4 at mRNA level in iNKT cells were analyzed by RT-PCR.Western blot assay was used to detect the levels of T-bet and GATA-3 in iNKT cells.Results CH2b significantly enhanced the proliferation of IL-2 activated iNKT cells isolated from the patients with active RA.CH2b promoted the secretion of IL-4,resulting in a decrease in the ratio of IFN-γ/IL-4.Moreover,CH2b promoted the expressions of GATA-3 and IL-4 at mRNA level in iNKT cells.Conclusion The novel immunostimulator,CH2b,might enhance the immunoregulatory effects of iNKT cells by promoting the GATA-3 pathway-mediated secretion of Th2-1ike cytokines and inducing the differentiation of Th0 to Th2 cells.

We conducted a randomized, open-label, parallel-controlled, multicenter trial on the use of Shuanghuanglian (SHL), a traditional Chinese patent medicine, in treating cases of COVID-19. A total of 176 patients received SHL by three doses (56 in low dose, 61 in middle dose, and 59 in high dose) in addition to standard care. The control group was composed of 59 patients who received standard therapy alone. Treatment with SHL was not associated with a difference from standard care in the time to disease recovery. Patients with 14-day SHL treatment had significantly higher rate in negative conversion of SARS-CoV-2 in nucleic acid swab tests than the patients from the control group (93.4% vs. 73.9%, P = 0.006). Analysis of chest computed tomography images showed that treatment with high-dose SHL significantly promoted absorption of inflammatory focus of pneumonia, which was evaluated by density reduction of inflammatory focus from baseline, at day 7 (mean difference (95% CI), -46.39 (-86.83 to -5.94) HU; P = 0.025) and day 14 (mean difference (95% CI), -74.21 (-133.35 to -15.08) HU; P = 0.014). No serious adverse events occurred in the SHL groups. This study illustrated that SHL in combination with standard care was safe and partially effective for the treatment of COVID-19.
