In December 2019, a new type viral pneumonia cases occurred in Wuhan, Hubei Province;and then named "2019 novel coronavirus(2019-nCoV)" by the World Health Organization(WHO) on 12 January 2020. For it is a never been experienced respiratory disease before and with infection ability widely and quickly, it attracted the world’s attention but without treatment and control manual. For the request from frontline clinicians and public health professionals of 2019-nCoV infected pneumonia management, an evidence-based guideline urgently needs to be developed. Therefore, we drafted this guideline according to the rapid advice guidelines methodology and general rules of WHO guideline development;we also added the first-hand management data of Zhongnan Hospital of Wuhan University. This guideline includes the guideline methodology, epidemiological characteristics, disease screening and population prevention, diagnosis, treatment and control(including traditional Chinese Medicine), nosocomial infection prevention and control, and disease nursing of the 2019-nCoV. Moreover, we also provide a whole process of a successful treatment case of the severe 2019-nCoV infected pneumonia and experience and lessons of hospital rescue for 2019-nCoV infections. This rapid advice guideline is suitable for the first frontline doctors and nurses, managers of hospitals and healthcare sections, community residents, public health persons, relevant researchers, and all person who are interested in the 2019-nCoV. 展开更多

AIM: To detect the expression of PTEN encoding productin normal mucosa, intestinal metaplasia (IM), dysplasia andcarcinoma of the stomach, and to investigate its clinicalimplication in tumorigenesis and progression of gastriccarcinoma.METHODS: Formalin-fixed paraffin embedded specimens from184 cases of gastric carcinoma, their adjacent normal mucosa,IM and dysplasia were evaluated for PTEN protein expressionby SABC immunohistochemistry. PTEN expression wascompared with tumor stage, lymph node metastasis, Lauren'sand WHO's histological classification of gastric carcinoma.Expression of VEGF was also detected in 60 cases of gastriccarcinoma and its correlation with PTEN was concerned.RESULTS: The positive rates of PTEN protein were 100 %(102/102), 98.5 %(65/66), 66.7 % (4/6) and 47.8 %(88/184)in normal mucosa, IM, dysplasia and carcinoma of the stomach,respectively. The positive rates in dysplasia and carcinomawere lower than in normal mucosa and IM (P<0.01).Advanced gastric cancers expressed less frequent PTEN thanearly gastric cancer (42.9 % v567.6 %, P<0.01). The positiverate of PTEN protein was lower in gastric cancer with thanwithout lymph node metastasis (40.3 % v563.3 %, P<0.01).PTEN was less expressed in diffuse-type than in intestinal-type gastric cancer (41.5 % v557.8 %,P<0.05). Signet ringcell carcinoma showed the expression of PTEN at the lowestlevel (25.0 %, 7/28); less than well and moderatelydifferentiated ones (P<0.01). Expression of PTEN was notcorrelated with expression of VEGF (P>0.05).CONCLUSION: Loss or reduced expression of PTEN proteinoccures commonly in tumorigenesis and progression of gastriccarcinoma. It is suggested that PTEN can be an objective markerfor pathologically biological behaviors of gastric carcinoma. 展开更多

AIM: To investigate the population-based prevalence of fatty liver disease (FLD) and its risk factors in Guangdong Province,China. METHODS: A cross-sectional survey with multiple-stage stratified cluster and random sampling of inhabitants over 7-year-old was performed in 6 urban and rural areas of Guangdong Province,China. Questionnaires,designed by co-working of epidemiologists and hepatologists,included demographic characteristics,current medication use,medical history and health-relevant behaviors,i.e. alcohol consumption,smoking habits,dietary habits and physical activities. Anthropometric measurements,biochemical tests and abdominal ultrasonography were carried out. RESULTS: Among the 3543 subjects,609 (17.2%) were diagnosed having FLD (18.0% males,16.7% females,P > 0.05). Among them,the prevalence of confirmed alcoholic liver disease (ALD),suspected ALD and nonalcoholic fatty liver disease (NAFLD) were 0.4%,1.8%,and 15.0%,respectively. The prevalence rate (23.0%) was significantly higher in urban areas than (12.9%) in rural areas. After adjustment for age,gender and residency,the standardized prevalence of FLD in adults was 14.5%. Among them,confirmed ALD,suspected ALD and NAFLD were 0.5%,2.3%,and 11.7%,respectively,in adults and 1.3% (all NAFLD) in children at the age of 7-18 years. The overall prevalence of FLD increased with age in both genders to the peak of 27.4% in the group of subjects at the age of 60-70 years. The prevalence rate was significantly higher in men than in women under the age of 50 years (22.4% vs 7.1%,P < 0.001). However,the opposite phenomenon was found over the age of 50 years (20.6% vs 27.6%,P < 0.05). Multivariate and logistic regression analysis indicated that male gender,urban residency,low education,high blood pressure,body mass index,waist circumference,waist to hip ratio,serum triglyceride and glucose levels were the risk factors for FLD. CONCLUSION: FLD,especially NAFLD,is prevalent in South China. There are many risk factors for FLD. 展开更多

Background Fluid therapy for severe acute pancreatitis (SAP) should not only resolve deficiency of blood volume, but also prevent fluid sequestration in acute response stage. Up to date, there has not a strategy for fluid therapy dedicated to SAP. So, this study was aimed to investigate the effects of fluid therapy treatment on prognosis of SAP. Methods Seventy-six patients were admitted prospectively according to the criteria within 72 hours of SAP onset. They were randomly assigned to a rapid fluid expansion group (Group I, n=36) and a controlled fluid expansion group (Group II n=-40). Hemodynamic disorders were either quickly (fluid infusion rate was 10-15 ml.kg-1-h-1, Group I) or gradually improved (fluid infusion rate was 5-10 ml-kg1.h-1, Group II) through controlling the rate of fluid infusion. Parameters of fluid expansion, blood lactate concentration were obtained when meeting the criteria for fluid expansion. And APACHE II scores were obtained serially for 72 hours. Rate of mechanical ventilation, incidence of abdominal compartment syndrome (ACS), sepsis, and survival rate were obtained. Results The two groups had statistically different (P 〈0.05) time intervals to meet fluid expansion criteria (Group I, 13.5±6.6 hours; Group II, (24.0±5.4) hours). Blood lactate concentrations were both remarkably lower as compared to the level upon admission (P 〈0.05) and reached the normal level in both groups upon treatment. It was only at day 1 that hematocrit was significantly lower in Group I (35.6%±6.8%) than in Group II (38.5%±5.4%) (P〈0.01). Amount of crystalloid and colloid in group I ((4028±1980)ml and (1336±816)ml) on admission day was more than those of group II ((2472±1871)ml and (970±633)ml). No significant difference was found in the total amount of fluids within four days of admission between the two groups (P〉0.05). Total amount of fluid sequestration within 4 days was higher in Group I ((5378±2751)ml� 展开更多

Cereal straw is one of the most abundant biomass burned in China but its contribution to fine particulates is not adequately understood. In this study, three main kinds of cereal straws were collected from five grain producing areas in China. Fine particulate matters (PMzs) from the cereal straws subjected to control burnings, both under smoldering and flaming status, were sampled by using a custom made dilution chamber and sampling system in the laboratory. Element carbon (EC) and organic carbon (OC) was analyzed. 141 compounds of organic matters were measured by gas chromatography-mass spectrum (GC-MS). Source profiles of particulate organic matters emitted from cereal straw burnings were obtained. The results indicated that organic matters contribute a large fraction in fine particulate matters. Levoglucosan had the highest contributions with averagely 4.5% in mass of fine particulates and can be considered as the tracer of biomass burnings. Methyloxylated phenols from lignin degradation also had high concentrations in PM2.5, and contained approximately equal amounts of guaiacyl and syringyl compounds. 13-Sitostrol also made up relatively a large fraction of PMz5 compared with the other sterols (0.18%-0.63% of the total fine particle mass). Normal alkanes, PAHs, fatty acids, as well as normal alkanols had relatively lower concentrations compared with the compounds mentioned above. Carbon preference index (CPI) of normal alkanes and alkanoic acids showed characteristics of biogenic fuel burnings. Burning status significantly influenced the formations of EC and PAHs. The differences between the emission profiles of straw and wood combustions were displayed by the fingerprint compounds, which may be used to identify the contributions between wood and straw burnings in source apportionment researches. 展开更多

Background XS0601, consisting of active ingredients (Chuangxiongol and paeoniflorin), has been shown to inhibit arterial neointimal hyperplasia in animal models and in preliminary human studies. The objective of this study was to evaluate the safety and efficacy of XS0601 in preventing restenosis following percutaneous coronary intervention (PCI). Methods A multi-center, randomized, double-blind, placebo-controlled trial was conducted. A total of 335 patients were randomized into treatment with the oral administration of XS0601, or a placebo for 6 months after successful PCI. Angiographic follow-up was scheduled at 6 months, and clinical follow-ups performed at 1, 3 and 6 months after PCI. The primary end point was angiographic restenosis. The secondary end points were the combined incidence of death, target lesion nonfatal myocardial infarction, repeat angioplasty, and coronary artery bypass graft surgery. Results A total of 308 patients (91.9%) completed the study and 145 cases (47.1%) received angiographic follow-up. The restenosis rates were significantly reduced in the XS0601 group as compared with the placebo group (26.0% vs. 47.2%, P 〈 0.05), and the minimum lumen diameter (MLD) was greater [(2.08 ± 0.89) mm for XS0601 vs. (1.73 ± 0.94) mm for placebo, P 〈 0.05]. XS0601 also significantly reduced the combined incidence of major adverse cardiac event (10.4% in the XS0601 group vs. 22.7% in the placebo group, P 〈 0.05). The incidence of recurrent angina at 3 and 6 months after PCI was also significantly reduced in XS0601 group (7.1% and 11.0%) as compared with those in placebo group (19.5% and 42.9%) (P 〈 0.05). No significant side effects occurred within the 6-month follow-up period in the XS0601 group.Conclusion Administration of XS0601 for 6 months is demonstrated to be safe and effective in reducing restenosis in post-PCI patients. 展开更多

Background: Atopic dermatitis (AD) is an inflammatory skin disease characterized by chronic recurrent dermatitis with profound itching. Most patients have personal and/or family history of atopic diseases. Several criteria have been proposed for the diagnosis of AD. Although the clinical features of childhood AD have been widely studied, there has been less large-scale study on adult/adolescent AD. The aim of this study was to investigate the clinical features of adult/adolescent patients with chronic symmetrical eczemaJAD and to propose Chinese diagnostic criteria for adult/adolescent AD. Methods: A hospital-based study was performed. Forty-two dermatological centers participated in this study. Adult and adolescent patients (12 years and over) with chronic symmetrical eczema or AD were included in this study. Questionnaires were completed by both patients and-investigators. The valid questionnaires were analyzed using EpiData 3.1 and SPSS 17.0 software. Results: A total of 2662 valid questionnaires were collected (1369 male and 1293 female). Of all 2662 patients, 2062 (77.5%) patients had the disease after 12 years old, while only 600 (22.5%) patients had the disease before 12 years old, suggesting late-onset eczema/AD is common. Two thousand one hundred and thirty-nine (80.4%) patients had the disease for more than 6 months. One thousand one hundred and forty-four (43.0%) patients had a personal and/or family history of atopic diseases. One thousand five hundred and forty-eight (58.2%) patients had an elevated total serum IgE and/or eosinophilia and/or positive allergen-specific IgE. Based on these clinical and laboratory features, we proposed Chinese criteria for adult/adolescent AD. Of all 2662 patients, 60.3% were satisfied with our criteria, while only 48.2% satisfied with Hanifin Rajka criteria and 32.7% satisfied with Williams criteria, suggesting a good sensitivity of our criteria in adult/adolescent AD patients. Conclusion: Late-onset of eczema or AD is common. Th 展开更多

Background:The optimal strategy for adjuvant therapy after curative resection for hepatocellular carcinoma(HCC)patients with solitary tumor and microvascular invasion(MVI)is controversial.This trial evaluated the efficacy and safety of adjuvant transcatheter arterial chemoembolization(TACE)after hepatectomy versus hepatectomy alone in HCC patients with a solitary tumor≥5 cm and MVI.Methods:In this randomized,open-labeled,phase III trial,HCC patients with a solitary tumor≥5 cm and MVI were randomly assigned(1:1)to receive either 1-2 cycles of adjuvant TACE after hepatectomy(Hepatectomy-TACE)or hepatectomy alone(Hepatectomy Alone).The primary endpoint was disease-free survival(DFS);the secondary end-points included overall survival(OS)and adverse events.Results:Between June 1,2009,and December 31,2012,250 patients were enrolled and randomly assigned to the Hepatectomy-TACE group(n=125)or the Hepatectomy Alone group(n=125).Clinicopathological characteristics were balanced between the two groups.The median follow-up time from randomization was 37.5 months[interquartile range 18.3-48.2 months].The median DFS was significantly longer in the Hepatectomy-TACE group than in the Hepatectomy Alone group[17.45 months(95%confidence interval[CI]11.99-29.14)vs.9.27 months(95%CI 6.05-13.70),hazard ratio[HR]=0.70(95%CI 0.52-0.95),P=0.020],respectively.The median OS was also significantly longer in the Hepatectomy-TACE group than in the Hepatectomy Alone group[44.29 months(95%CI 25.99-62.58)vs.22.37 months(95%CI 10.84-33.91),HR=0.68(95%CI 0.48-0.97),P=0.029].Treatment-related adverse events were more frequently observed in the Hepatectomy-TACE group,although these were generally mild and manageable.The most common grade 3 or 4 adverse events in both groups were neutropenia and liver dysfunction.Conclusion:Hepatectomy followed by adjuvant TACE is an appropriate option after radical resection in HCC patients with solitary tumor≥5 cm and MVI,with acceptable toxicity. 展开更多
