Degos'disease is a systemic necrotizing vasculitis. Skin biopsy can confirm its diagnosis. Severe systemic complication should be prevented. Degos'disease should be considered in the differential diagnosis of skin lesions associated with systemic involvement.

Objective To discuss of the therapeutic effects of treating three TCM types of Chronic superficial gastritis (CSG)disharmony of liver and stomach, weakness of the spleen and the stomach, and damp heat in the spleen and the stomach with chinese medicine, and to discuss its impact on the changes of three gastrointestinal hormones-- motilin (MTL), gastrin (GAS), and somatostatin (SS). Methods The data of 150 CSG patients in Shenzhen Bao’an Hospital from Feb, 2011 to Mar, 2013 were selected. These patients belonged to three kinds of syndrome, which was disharmony of liver and stomach, weakness of the spleen and the stomach, and damp heat in the spleen and the stomach, each syndrome had 50 cases. Different Chinese medicines were applied to different syndrome of patients. After one month treatment, the therapeutic effects and the changes of MTL, GAS, SS in these patients were detected by radioimmunoassay. Results After treatment, the total effective rate of the damp heat in the spleen and the stomach syndrome was 94%, the weakness of the spleen and the stomach type was 88%, disharmony of liver and stomach type was 90%, the difference was not statistically significant among the three types(χ2=3.84, P>0.05);after treatment, the serum MTL, SS level of disharmony of liver and stomach, weakness of the spleen and the stomach, and damp heat in the spleen and the stomach type were [damp heat in the spleen and the stomach type were (240.25±7.29)pg/ml, (68.23± 5.97)pg/ml;the weakness of the spleen and the stomach type were (260.16±8.84)pg/ml, (75.35±4.65)pg/ml;disharmony of liver and stomach type were(258.32±15.23)pg/ml, (80.12±7.88)pg/ml] higher than before treatment [damp heat in the spleen and the stomach type were (87.26±7.58)pg/ml, (49.34±4.93)pg/ml;the weakness of the spleen and the stomach type were (67.11±7.81)pg/ml, (57.15±5.11)pg/ml; disharmony of liver and stomach type were (89.26±7.60)pg/ml, (40.63±7.26)pg/ml], and the levels of serum GAS [(156.38±17.36)pg/ml, (146.15±15.56)pg/ml, (140.26±13.37)pg/ml] was lower than before treatment [(274.59 ± 17.82)pg/ml, (320.83 ± 15.02)pg/ml, (216.15 ± 13.77)pg/ml], the difference was statistically significant (P<0.05 or 0.01). Conclusions The changes of three hormones-MTL, GAS, SS can be used as an objective basis for the diagnosis and the judgment of healing efficacy of CSG treated by traditional Chinese medicine.

Objective:To analyze the current status of neonatal nosocomial infection research at home and abroad, explore its research hotspots and development trends, and provide evidence for further research on the prevention and treatment of neonatal nosocomial infection.Methods:The Chinese and English literature related to neonatal nosocomial infection included in CNKI and Web of Science Database from 2010 to 2021 were searched, and CiteSpace 6.1.R2 and VOSviewer1.6.18 software were used to map the authors, institutions, countries, and keywords of the included literature. At the same time, the burst item map was used to predict the future research development trends to a certain extent.Results:A total of 235 authors and 2 core teams of Chinese literature (1 639 articles), 157 authors and 2 core teams of English literature (1 322 articles) were analyzed. 659 Chinese keywords and 1 330 English keywords were extracted, including "nosocomial infection", "risk factors", "infection", "epidemiology", etc. From these literature, 13 Chinese literature clusters and 6 English clusters were generated, and the clustering results were significant and reasonable. The current research hotspots in China focused on pregnancy outcomes and nursing management, while the hotspots of foreign researches focused on sequelae and disease burden.Conclusions:Compared with international research, domestic research on neonatal nosocomial infection hasn't combined with social, environmental and other related factors, while international research teams have begun to shift the focus of research on neonatal nosocomial infections to disease burden and infection sequelae. In the future, cooperation between domestic and foreign research teams should be strengthened, focusing on the frontier trend of international research, and improving the depth and breadth of research.

Recent studies of exosomes derived from mesenchymal stem cells (MSCs) have indicated high potential clinical applications in many diseases. However, the limited source of MSCs impedes their clinical research and application. Most recently, induced pluripotent stem cells (iPSCs) have become a promising source of MSCs. Exosome therapy based on iPSC-derived MSCs (iMSCs) is a novel technique with much of its therapeutic potential untapped. Compared to MSCs, iMSCs have proved superior in cell proliferation, immunomodulation, generation of exosomes capable of controlling the microenvironment, and bioactive paracrine factor secretion, while also theoretically eliminating the dependence on immunosuppression drugs. The therapeutic effects of iMSC-derived exosomes are explored in many diseases and are best studied in wound healing, cardiovascular disease, and musculoskeletal pathology. It is pertinent clinicians have a strong understanding of stem cell therapy and the latest advances that will eventually translate into clinical practice. In this review, we discuss the various applications of exosomes derived from iMSCs in clinical medicine.

Objective To explore the effect of decreased air pollutants concentrations on the incidence of Type 2 Diabetes Mellitus (T2DM). Methods A prospective cohort was designed in Tianjin where the air quality gradually improved from 2014 to 2018. A total of 5 077 community residents (18-90 years old) were recruited as the baseline population from 2013 to 2014. From 2014 to 2018 follow-up was carried out year by year to observe the new incidence of T2DM in the cohort. The HR and 95%CI (95% confidence interval) were calculated with the multiple Cox proportional hazard regression model to evaluate the effect of the decrease in the concentrations of SO₂, NO₂, and particulate matters with diameters <10μm and <2.5μm (PM₁₀, PM_2.5) on the incidence of T2DM. Results The cohort was followed up year by year from 2014 to 2018, with a cumulative follow-up of 25 385 person-years over the 5 years. At the same time, the air quality of Tianjin was significantly improved. Statistical analysis results after covariate adjustment revealed that the risk of T2DM in the population decreased by 0.172, 0.124, and 0.210 times, for a decrease of 10 μg/m³ in the annual average concentrations of SO₂, PM₁₀, and PM_2.5 each, respectively (SO2：HR=0.828，95%CI=0.757-0.907；PM₁₀：HR=0.876，95%CI=0.816-0.941；PM_2.5：HR=0.790，95%CI=0.694-0.899). Conclusion The implementation of environmental protection measures to improve air pollution could reduce the risk of T2DM in the population and control the increasing prevalence.
