Major earthquakes often result in incalculable environmental damage, loss of life, and threats to health. Tremendous progress has been made in response to many medical challenges resulting from ...earthquakes. However, emergency medical rescue is complicated, and great emphasis should be placed on its organisation to achieve the best results. The 2008 Wenchuan earthquake was one of the most devastating disasters in the past 10 years and caused more than 370 000 casualties. The lessons learnt from the medical disaster relief effort and the subsequent knowledge gained about the regulation and capabilities of medical and military back-up teams should be widely disseminated. In this Review we summarise and analyse the emergency medical rescue efforts after the Wenchuan earthquake. Establishment of a national disaster medical response system, an active and effective commanding system, successful coordination between rescue forces and government agencies, effective treatment, a moderate, timely and correct public health response, and long-term psychological support are all crucial to reduce mortality and morbidity and promote overall effectiveness of rescue efforts after a major earthquake.
Abstract The study was to investigate the clinical characteristics and significance of antinuclear antibody (ANA) cytoplasmic patterns in ANCA-associated vasculitis (AAV) from Southwest China. A ...retrospective study including 232 AAV patients from Peoples Hospital of Deyang City was performed. These included 115 patients with ANA cytoplasmic pattern as observation group and 117 patients without ANA cytoplasmic pattern as control group. Chest involvement (60.00 vs 46.15, P = .035), cardiovascular involvement (5.21 vs 29.91, P < .001), and renal involvement (37.39 vs 77.78, P = .001) were different between groups. Total protein (69.55 vs 64.01, P < .001), triglyceride (1.41 vs 1.18, P = .023), mean cell volume (89.76 vs 87.59, P = .040), and estimated glomerular filtration rate (76.67 vs 50.87, P = .035) were higher in ANA cytoplasmic patterns group. Creatinine (73.00 vs 117.50, P = .011), white blood cell (6.93 vs 8.86, P = .001), platelet (196.0 vs 239.0, P = .017), anti-myeloperoxidase (2.44 vs 3.42, P = .042), and anti-proteinase 3 (1.00 vs 4.93, P = .007) were lower in this group. In multivariate analysis, creatinine (odds ratio OR = 1.21, 95% confidence interval CI: 1.06–1.38), triglyceride (OR = 1.97, 95% CI: 1.10–3.48), and anti-myeloperoxidase (OR = 1.64, 95% CI: 1.37–1.95) were independent risk factors of AAV renal involvement. Total protein (OR = .95, 95% CI: 0.91–0.99) was an independent protective factor of AAV renal involvement. Chi-square test showed that speckled pattern was different among anti-neutrophil cytoplasmic antibody patterns ( χ 2 = 18.526, P < .001). In summary, HEp-2 cell cytoplasmic patterns have certain clinical significance in AAV, which is a new exploration of the clinical value of ANA.
Summary Background The prognosis of patients with relapsed Hodgkin's lymphoma, especially those who relapse after stem-cell transplantation, is poor, and the development of new agents for this ...patient population is an unmet medical need. We tested the safety and efficacy of mocetinostat, an oral isotype-selective histone deacetylase inhibitor, in patients with relapsed classical Hodgkin's lymphoma. Methods Patients with relapsed or refractory classical Hodgkin's lymphoma aged 18 years or older were treated with mocetinostat administered orally three times per week, in 28-day cycles. Two doses were assessed (85 mg and 110 mg). Patients were treated until disease progression or prohibitive toxicity. The primary outcome was disease control rate, defined as complete response, partial response, or stable disease (for at least six cycles), analysed by intention to treat. This trial has been completed and is registered with ClinicalTrials.gov , number NCT00358982. Findings 51 patients were enrolled. Initially, 23 patients were enrolled in the 110 mg cohort. Subsequently, because toxicity-related dose reductions were necessary in the 110 mg cohort, we treated 28 additional patients with a dose of 85 mg. On the basis of intent-to-treat analysis, the disease control rate was 35% (eight of 23 patients) in the 110 mg group and 25% (seven of 28) in the 85 mg group. 12 patients (24%) discontinued treatment because of adverse events, nine (32%) in the 85 mg cohort and three (13%) in the 110 mg cohort. The most frequent treatment-related grade 3 and 4 adverse events were neutropenia (four patients 17% in the 110 mg group, three 11% in the 85 mg group); fatigue (five patients 22% in the 110 mg group, three 11% in the 85 mg group); and pneumonia (four patients 17% in the 110 mg group, two 7% in the 85 mg group). Four patients, all in the 110 mg cohort, died during the study, of which two might have been related to treatment. Interpretation Mocetinostat, 85 mg three times per week, has promising single-agent clinical activity with manageable toxicity in patients with relapsed classical Hodgkin's lymphoma.

A comprehensive evaluation of the burden of injury is an important foundation for selecting and formulating strategies of injury prevention. We present results from the Global Burden of Diseases, ...Injuries, and Risk Factors Study (GBD) 2017 of non-fatal and fatal outcomes of injury at the national and subnational level, and the changes in burden for key causes of injury over time in China.
Using the methods and results from GBD 2017, we describe the burden of total injury and the key causes of injury based on the rates of incidence, cause-specific mortality, and disability-adjusted life years (DALYs) in China estimated using DisMod-MR 2.1. We additionally evaluated these results at the provincial level for the 34 subnational locations of China in 2017, measured the change of injury burden from 1990 to 2017, and compared age-standardised DALYs due to injuries at the provincial level against the expected rates based on the Socio-demographic Index (SDI), a composite measure of development of income per capita, years of education, and total fertility rate.
In 2017, in China, there were 77·1 million (95% uncertainty interval UI 72·5–81·6) new cases of injury severe enough to warrant health care and 733 517 deaths (681 254–767 006) due to injuries. Injuries accounted for 7·0% (95% UI 6·6–7·2) of total deaths and 10·0% (9·5–10·5) of all-cause DALYs in China. In 2017, there was a three-times variation in age-standardised injury DALY rates between provinces of China, with the lowest value in Macao and the highest in Yunnan. Between 1990 and 2017, the age-standardised incidence rate of all injuries increased by 50·6% (95% UI 46·6–54·6) in China, whereas the age-standardised mortality and DALY rates decreased by 44·3% (41·1–48·9) and 48·1% (44·6–51·8), respectively. Between 1990 and 2017, all provinces of China experienced a substantial decline in DALY rates from all injuries ranging from 16·3% (3·1–28·6) in Shanghai and 60·4% (53·7–66·1) in Jiangxi. Age-standardised DALY rates for drowning; injuries from fire, heat and hot substances; adverse effects of medical treatments; animal contact; environmental heat and cold exposure; self-harm; and executions and police conflict each declined by more than 60% between 1990 and 2017.
Between 1990 and 2017, China experienced a decrease in the age-standardised DALY and mortality rates due to injury, despite an increase in the age-standardised incidence rate. These trends occurred in all provinces. The divergent trends in terms of incidence and mortality indicate that with rapid sociodemographic improvements, the case fatality of injuries has declined, which could be attributed to an improving health-care system but also to a decreasing severity of injuries over this time period.

Podoplanin (PDPN) promotes platelet aggregation and activation by interacting with C-type lectin-like receptor 2(CLEC-2) on platelets. The interaction between the upregulated PDPN and platelet CLEC-2 ...stimulates venous thrombosis. PDPN was identified as a risk factor for coagulation and thrombosis in inflammatory processes. Hypercoagulability is defined as the tendency to develop thrombosis according to fibrinogen and/or D dimer levels. Nephrotic syndrome is also considered to be a hypercoagulable state. The aim of this study is to investigate the association of soluble PDPN/CLEC-2 with hypercoagulability in nephrotic syndrome. Thirty-five patients with nephrotic syndrome and twenty-seven healthy volunteers were enrolled. PDPN, CLEC-2 and GPVI concentrations were tested by enzyme-linked immunosorbent assay (ELISA). Patients with nephrotic syndrome showed higher serum levels of PDPN and GPVI in comparison to healthy controls (P < .001, P = .001). PDPN levels in patients with nephrotic syndrome were significantly correlated with GPVI (r = 0.311; P = .025), hypoalbuminemia (r = −0.735; P < .001), hypercholesterolemia (r = 0.665; P < .001), hypertriglyceridemia (r = 0.618; P < .001), fibrinogen (r = 0.606; P < .001) and D-dimer (r = 0.524; P < .001). Area under the curve (AUC) for the prediction of hypercoagulability in nephrotic syndrome using PDPN was 0.886 (95% CI 0.804-0.967, P < .001). Cut-off value for the risk probability was 5.88 ng/ml. The sensitivity of PDPN in predicting hypercoagulability was 0.806, and the specificity was 0.846. When serum PDPN was >5.88 ng/ml, the risk of hypercoagulability was significantly increased in nephrotic syndrome (OR = 22.79, 95% CI 5.92-87.69, P < .001). In conclusion, soluble PDPN levels were correlated with hypercoagulability in nephrotic syndrome. PDPN has the better predictive value of hypercoagulability in nephrotic syndrome as well as was a reliable indicator of hypercoagulable state.
Abstract The purpose of this study was to evaluate the effectiveness of application of muscle relaxants and celecoxib in early recovery after total knee arthroplasty (TKA). One hundred and fifty ...patients were randomized 1:1:1 to receive either both of muscle relaxants and celecoxib or muscle relaxants alone or placebo for 2 weeks (50 patients in each group). VAS pain scores as primary efficacy, active range of motion, morphine consumption, blood loss, and postoperative complications including postoperative nausea and vomiting (PONV), extremities myasthenia and deep vein thrombosis (DVT) were determined postoperatively. Group A improved better with reduced VAS pain scores compared with another two groups. These results demonstrated that application of muscle relaxants and celecoxib into patients undergoing TKA for 2 weeks postoperative consequently improved their convalescence.
Abstract Background Cancer patients are at increased risk of venous thromboembolism; however, the incidence and risk factors for venous thromboembolism in lymphoma patients are not well defined. ...Methods Medical records of 422 newly referred lymphoma patients at our institution were reviewed over 2-year follow-up for all venous thromboembolism events and potential risk factors. Multivariate logistic regression model was used to identify risk factors predictive of venous thromboembolism. Results Among 422 patients, 72 (17.1 %) had 80 new episodes of venous thromboembolism: 59 had deep vein thrombosis, 17 had pulmonary embolism, and 4 had combined deep vein thrombosis and pulmonary embolism. Only 18 of 422 patients (4.3%) were on thromboprophylaxis at baseline. Interestingly, 64% (51/80) of the episodes occurred by the third cycle of chemotherapy. By multivariate logistic regression, female sex (odds ratio OR 3.51, P = .001), high hemoglobin (OR 1.26, P = .020), high serum creatinine (OR 3.23, P = .009), and doxorubicin- or methotrexate-based chemotherapy (OR 3.47, P = 0.003) were important risk factors for new venous thromboembolism. Conclusions Lymphoma patients are at high risk for venous thromboembolism in the initial cycles of chemotherapy; the risk was higher for women, patients with elevated hemoglobin or creatinine, or those receiving doxorubicin or methotrexate. Future studies might focus on validation of these risk factors to identify the high-risk cohort and the potential role of thromboprophylaxis, particularly during initial cycles of chemotherapy.
Abstract Purpose Clinical care has become increasingly dependent on computerized physician order entry (CPOE) systems. No study has reported the adverse effect of CPOE on physicians’ ability to ...handwrite prescriptions. This study took advantage of an extensive crash of the CPOE system at a large hospital to assess the completeness, legibility, and accuracy of physicians’ handwritten prescriptions. Methods The CPOE system had operated at the outpatient department of an academic medical center in Taiwan since 1993. During an unintentional shutdown that lasted 3.5 hours in 2010, physicians were forced to write prescriptions manually. These handwritten prescriptions, together with clinical medical records, were later audited by clinical pharmacists with respect to 16 fields of the patient’s, prescriber’s, and drug data. Findings A total of 1418 prescriptions with 3805 drug items were handwritten by 114 to 1369 patients. Not a single prescription had all necessary fields filled in. Although the field of age was most frequently omitted (1282 90.4% of 1418 prescriptions) among the patient’s data, the field of dosage form was most frequently omitted (3480 91.5% of 3805 items) among the drug data. In contrast, the scale of illegibility was rather small. The highest percentage reached only 1.5% (n = 57) in the field of drug frequency. Inaccuracies of strength, dose, and drug name were observed in 745 (19.6%), 517 (13.6%), and 435 (11.4%) prescribed drug items, respectively. Implications The unintentional shutdown of a long-running CPOE system revealed that physicians fail to handwrite flawless prescriptions in the digital era. The contingency plans for computer disasters at health care facilities might include preparation of stand-alone e-prescribing software so that the service delay could be kept to the minimum. However, guidance on prescribing should remain an essential part of medical education.
Purpose
The malignant transformation of cells can lead to aerobic glycolysis, an important form of metabolic reprogramming in colon cancer cells, which can cause the accumulation of lactate and ...accelerate the proliferation of tumor cells also enhance their chemotherapy drug resistance. The aim of this study was to investigate the possible molecular mechanisms responsible for the increased lactate expression in colon cancer.
Methods
Several bioinformatics methods, including differential analysis, gene ontology enrichment, univariate and multivariate Cox regression analysis were used to find the lactic acid–related gene carnitine palmitoyltransferase 2. We analyzed the relationship between carnitine palmitoyltransferase 2 and clinical features as well as immune microenvironment. To further explore the mechanism of carnitine palmitoyltransferase 2 in colon cancer, we performed methylation analysis and constructed a competitive endogenous RNA network, which was validated in cell lines and clinical specimens.
Results
We used bioinformatics to select the lactic acid–related gene carnitine palmitoyltransferase 2 and found low expression of carnitine palmitoyltransferase 2 was associated with poor prognosis in colon cancer. An inhibitory tumor microenvironment was created when carnitine palmitoyltransferase 2 expression was reduced, with decreased CD4 T cells, CD8 T cells, dendritic cells, and B cells but increased cancer-associated fibroblasts. Methylation analysis showed that the abnormal decrease in carnitine palmitoyltransferase 2 might be caused by hypermethylation. We constructed a network of SGMS1-AS1/microRNA-106a-5p/carnitine palmitoyltransferase 2 and verified their expression in cell lines and clinical specimens.
Conclusion
Our work revealed the possible mechanism of lactate accumulation in colon cancer and explored a new potential treatment for colon cancer by cutting off aerobic glycolysis in tumor cells.
