Abstract
Objective: To investigate the epidemiological characteristics and genotype trends of rotavirus infection among the population with diarrhea in China, from 2009 to 2020 and provide evidence for strategic surveillance and prevention. Methods: Surveillance data on diarrhea syndrome from 252 sentinel hospitals across 28 provinces (municipalities, autonomous regions) were obtained from the information management system of the Infectious Disease Surveillance Technology Platform of the National Science and Technology Major Project. Descriptive epidemiological methods were employed to analyze the distribution of rotavirus diarrhea cases in different climatic zones, populations, and times from 2009 to 2020, as well as the genotyping characteristics and changing trends of group A rotavirus diarrhea cases. Results: From 2009 to 2020, a total of 114 606 diarrhea cases were tested for rotavirus, and the positive rate was 19.1% (21 872/114 606); group A rotavirus was dominant (98.2%, 21 471/21 872). The positive rate of rotavirus was the highest in 2009 (36.9%, 2 436/6 604) and 2010 (30.6%, 5 130/16 790), fluctuated between 14.0% to 18.0% from 2011 to 2017, raised slightly in 2018 (20.3%, 2 211/10 900), and declined continuously in the following two years (15.5%, 2 262/14 611 and 9.5%, 470/4 963). The positive rate of males (20.2%, 13 660/67 471) was significantly higher than that of females (17.4%, 8 212/47 135). Children under five had the highest positive rate (28.4%, 18 261/64 300), more than four times that of adults. The positive rate peaked from December to February in the mediate temperate zone, warm temperate zone, and subtropical zone, while there were two peaks from November to January and May to June in the frigid zone of the plateau. The dominant genotype of group A rotavirus gradually changed from G3P[8] and G1P[8] to G9P[8] during 2009-2020. Conclusions: The overall rotavirus infection rate in China was on a downward trend. Meanwhile, significant variations of positive rates were observed in seasonal epidemics and different age groups from 2009 to 2020. Rotavirus diarrhea in children was still a prominent concern. Vaccination of rotavirus vaccine should be promoted, and the epidemiological characteristics and genotypes of rotavirus diarrhea should be continuously monitored.

Abstract
Hemiboea pterocaulis is a unique species only found in Guilin, Guangxi, China. In this study, we sequenced and assembled the complete chloroplast genome of H. pterocaulis and revealed its phylogenetic relationship with other Hemiboea species. The chloroplast genome sequence of H. pterocaulis is 153,159 bp in length and comprises a large single-copy (LSC) region of 84,178 bp, a small single-copy (SSC) region of 18,087 bp, and a pair of inverted repeat (IR) regions, each with a length of 25,447 bp. It has a total GC content of 37.6% and encodes 132 genes, including 87 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The phylogenetic relationships based on the complete chloroplast genome sequences of Hemiboea taxa indicate that H. pterocaulis is most closely related to H. suiyangensis, indicating that H. pterocaulis is an independent species and is separated from the H. subcapitata complex. These results provide valuable insights into the phylogeny, species divergence, and delimitation of the Hemiboea genus.

Abstract
Objective: To investigate the diagnostic value of lung ultrasound in hospitalized children with community-acquired pneumonia (CAP). Methods: In the cross-sectional study, a total of 422 children with CAP who were hospitalized in the Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University, from February 2021 to August 2022 and completed lung ultrasound examination within 48 hours after admission were enrolled. The clinical characteristics, lung ultrasound and chest CT were collected. The patients were divided into two groups according to the signs of pneumonia indicated by chest CT, and the signs of lung ultrasound with diagnostic value were screened according to the signs of pneumonia indicated by chest CT by least absolute shrinkage and selection operator (Lasso) regression. According to severity of the disease, the children were divided into the severe group and the mild group, and the differences of lung ultrasound signs between the two groups were compared. Kruskal-Wallis test, Fisher's exact test was selected for comparison between groups. Random forest classifier wes used to evaluate the value of lung ultrasound in the diagnosis of CAP and prediction of severe pneumonia in children. The receiver operating characteristic curve was used to evaluate the prediction effect. Use DeLong test to compare the area under the curve. Results: Among the 422 cases of CAP, there were 258 males and 164 females, and the age of onset was 2.8 (1.3, 4.3) years. The confluent B-line, consolidation and pleural effusion detected by lung ultrasound were 309 cases (73.2%), 232 cases (55.0%) and 16 cases (3.8%), respectively, and the size of consolidation was 3.0 (0, 11.0) mm. One hundred and ten children (26.1%) with CAP completed chest CT. There were 90 cases with signs of pneumonia in chest CT and 20 cases without signs of pneumonia. Lasso was used for feature selection.Lung consolidation (OR=2.46), bilateral lung consolidation (OR=1.16) and confluent B-line (OR=1.34) were the main index. With random forest classifier, the accuracy of models using full variables and Lasso-selected variables were 0.79 (95%CI 0.70-0.86) and 0.79 (95%CI 0.70-0.86), the sensitivity were 0.81 and 0.81, and the specificity were 0.75 and 0.70, and the area under curve were 0.87 (95%CI 0.81-0.94, P<0.001) and 0.84 (95%CI 0.76-0.91, P<0.001), respectively. There were 97 cases in severe group and 325 cases in mild group. Compared with the mild group, the detection rate of consolidation, multiple consolidation, the size of consolidation and the size of consolidation was adjusted by body surface area (consolidation size/body surface area) in severe group were higher (66 cases (68.0%) vs. 166 cases (51.1%), 42 cases (43.3%) vs. 93 cases (28.6%), 8.0 (0, 17.0) vs. 1.0 (0, 9.0) mm, 12.5 (0, 24.6) vs. 2.1 (0, 17.6), χ2=8.59, 9.98, Z=14.40, 12.79, all P<0.05). Using lung ultrasound lung consolidation size and consolidation size/body surface area to predict the severe CAP, the optimal cut-off value were 6.7 mm and 10.2, the accuracy was 0.80 (95%CI 0.75-0.83) and 0.89 (95%CI 0.86-0.92), the sensitivity was 0.99 and 0.99, the specificity was 0.14 and 0.56, respectively, and the area under the curve was 0.66 (95%CI 0.60-0.72, P<0.001) and 0.76 (95%CI 0.70-0.83, P<0.001), respectively. The area under the curve of consolidation size/body surface area was higher than that of consolidation size (Z=5.50, P<0.001). Conclusions: Consolidation and confluent B-line, are important index for lung ultrasound diagnosis of CAP in children. The actual consolidation size adjusted by body surface area is superior to the size of consolidation in predicting severe CAP.

Abstract
Objective: To introduce the progress in research of rash and fever syndrome (RFS) surveillance and early warning both at home and abroad, and provide reference for surveillance and prevention of RFS in China. Methods: The keywords "fever" "rash" and "surveillance" and others were used for a literature retrieval by using China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, PubMed and Web of Science. The languages of literatures were limited in Chinese and English. The key information of the literatures were collected and analyzed with Excel. Results: A total of 36 study papers (21 in Chinese and 15 in English) were included. The studies mainly focused on the pathogen surveillance of RFS (n=19). The pathogens included measles virus, varicella-zoster virus, rubella virus, enterovirus, human B19 virus, dengue virus, streptococcus group A, Salmonella typhi and Salmonella paratyphoid,human herpesvirus, mumps virus and adenovirus. Eight studies were about the surveillance in major events, such as sport game, World Expo and religious gathering, or sudden natural disasters, such as earthquake and tropical storm, during 2010-2015. Eight studies focused on case or epidemic surveillance, most of which were studies from other counties. The surveillance sites were medical institutions. RFS was diagnosed according to the International Classification of Diseases, 9th (ICD-9) and symptoms descripted in chief-complaint. Only one study in Mongolia conducted RFS epidemic prediction. The analysis methods of 36 papers included simple descriptive analysis, time-based early warning models (such as regression analysis, fixed threshold method, Hugh Hart control chart method and cumulative sum control chart method) and time series analysis method. Conclusions: In the future, RFS surveillance system should cover both known pathogens and emerging pathogens. Automatic surveillance using information capture and intelligent modelling can be applied to improve the sensitivity and specificity of RFS surveillance and early warning.

Abstract
Objective: To analyze the audiology and occupational health data of applicants diagnosed of occupational noise deafness, and to explore the influencing factors in the diagnosis of suspected occupational noise deafness. Methods: In May 2022, the information of patients diagnosed with occupational noise deafness in Peking University Third Hospital from January 2018 to December 2021 was collected, and the occupational health data of their working environment, clinical audiological examination results and diagnosis basis of occupational noise deafness were collected and analyzed. Multi-factor unconditional logistic regression analysis was used to analyze independent risk factors for the diagnosis of occupational noise deafness. Results: A total of 129 subjects were included, all of which were suspected cases of occupational noise deafness found in various occupational health examination institutions. Eight cases (6.20%) were diagnosed as occupational noise deafness, and 121 cases (93.80%) were non-occupational noise deafness. After hearing examination, only 27.27% (24/88) of the patients' audiological changes were consistent with the starting point of occupational noise deafness diagnosis. Further analysis of the noise intensity in the workplace showed that 16 patients were identified as non-occupational noise deafness because the noise intensity of the working environment was less than 85 dB. Logistic regression analysis showed that the working hours were more than 8 hours (OR=9.274, 95%CI: 1.388-61.950, P=0.022) and the noise intensity of the working environment (OR=1.189, 95%CI: 1.059-1.334, P=0.003) were independent risk factors for the diagnosis of occupational noise deafness. Conclusion: The exclusion rate of suspected occupational noise deafness found in occupational health examination is higher after adequate rest. The test results of working environment noise intensity provided by the employer can help to determine occupational noise deafness.

Abstract
Objective: To explore the pathogenesis and risk factors of gallstone formation. Methods: The findings of hepatobiliary ultrasound and related data were collected from healthy subjects who underwent a physical examination at Xuanwu Hospital of Capital Medical University from January 2012 to December 2021. A total of 98 344 healthy subjects were included in the study,including 48 241 males and 50 103 females,with a ratio of 1∶1.03,aged (42.0±15.6)years(range:14 to 97 years). The gender,age,body mass index,waist circumference,systolic pressure,diastolic pressure,ALT,AST,total bilirubin,fasting blood glucose,triglyceride,total cholesterol,low-density lipoprotein,high-density lipoprotein were collected.Healthy subjects were required to sit for at least 10 minutes before blood pressure was measured.Rresults of fasting venous blood were collected after 8 to 12 hours on an empty stomach.According to the presence of gallstones by ultrasound results, healthy subjects were divided into study group and control group. Data were analyzed by rank-sum tests and χ2 test, and risk factors for gallstone formation were explored by Logistic regression analysis. Results: The incidence of gallstones in this group was 5.42%(5 333/98 344). Among them,the incidence of gallstones in people aged 60 years and above was significantly higher than that in people under 60 years old(15.31%(2 348/15 334) vs. 3.60%(2 985/83 010), χ2=3 473.46,P<0.05).The healthy subjects were divided by age for every 10 years,and the results showed that the incidence of gallstones increased with age. The incidence of gallstones in females was 5.68%(2 844/50 103),greater than 5.16%(2 489/48 241) in males(χ2=11.81,P<0.05). Among them,1 478 cases underwent gallbladder surgical resection due to gallstones,and the operation rate was 27.71%. The operation rate reached the peak between 60 and <70 years old,and decreased after 70 years old. The results of the multivariate analysis showed that,female(OR=1.38, P<0.01),age(OR=1.58, P<0.01),body mass index≥24 kg/m2(OR=1.31, P<0.01),waist circumference≥85 cm(OR=1.24, P<0.01),fasting blood glucose>6.1 mmol/L(OR=1.18,P<0.01),total cholesterol≥5.18 mmol/L(OR=0.87, P=0.019),low-density lipoprotein≥3.37 mmol/L(OR=1.15,P=0.001) were the risk factors for gallstone formation;high-density lipoprotein≥1.55 mmol/L(OR=0.87, P<0.01) was a protective factor for gallstone formation. Conclusions: The incidence of gallstones increases with age in male and female. Gender,age,body mass index,waist circumferenc,fasting blood glucose,total cholesterol,LDL,and HDL are related factors with gallstone formation.

Abstract
Objectives: To examine the influence of adjuvant chemotherapy after radical resection on the survival of patients with intrahepatic cholangiocarcinoma(ICC) and to identify patients who may benefit from it. Methods: The clinical and pathological data of 654 patients with ICC diagnosed by postoperative pathology from December 2011 to December 2017 at 13 hospitals in China were collected retrospectively. According to the inclusion and exclusion criteria,455 patients were included in this study,including 69 patients (15.2%) who received adjuvant chemotherapy and 386 patients (84.8%) who did not receive adjuvant chemotherapy. There were 278 males and 177 females,with age of 59 (16) years (M(IQR))(range:23 to 88 years). Propensity score matching (PSM) method was used to balance the difference between adjuvant chemotherapy group and non-adjuvant chemotherapy group. Kaplan-Meier method was used to plot the survival curve,the Log-rank test was used to compare the difference of overall survival(OS) and recurrence free survival(RFS)between the two groups. Univariate analysis was used to determine prognostic factors for OS. Multivariate Cox proportional hazards models were then performed for prognostic factors with P<0.10 to identify potential independent risk factors. The study population were stratified by included study variables and the AJCC staging system,and a subgroup analysis was performed using the Kaplan-Meier method to explore the potential benefit subgroup population of adjuvant chemotherapy. Results: After 1∶1 PSM matching,69 patients were obtained in each group. There was no significant difference in baseline data between the two groups (all P>0.05). After PSM,Cox multivariate analysis showed that lymph node metastasis (HR=3.06,95%CI:1.52 to 6.16,P=0.039),width of resection margin (HR=0.56,95%CI:0.32 to 0.99,P=0.044) and adjuvant chemotherapy (HR=0.51,95%CI:0.29 to 0.91,P=0.022) were independent prognostic factors for OS. Kaplan-Meier analysis showed that the median OS time of adjuvant chemotherapy group was significantly longer than that of non-adjuvant chemotherapy group (P<0.05). There was no significant difference in RFS time between the adjuvant chemotherapy group and the non-adjuvant chemotherapy group (P>0.05). Subgroup analysis showed that,the OS of female patients,without HBV infection,carcinoembryonic antigen<9.6 μg/L,CA19-9≥200 U/ml,intraoperative bleeding<400 ml,tumor diameter>5 cm,microvascular invasion negative,without lymph node metastasis,and AJCC stage Ⅲ patients could benefit from adjuvant chemotherapy (all P<0.05). Conclusion: Adjuvant chemotherapy can prolong the OS of patients with ICC after radical resection,and patients with tumor diameter>5 cm,without lymph node metastasis,AJCC stage Ⅲ,and microvascular invasion negative are more likely to benefit from adjuvant chemotherapy.

Abstract
Objective: To investigate the changes in kidney and its mechanism during the development of acute phosgene exposure in rats. Methods: Rats were randomized into 2 groups: control and phosgene group (including 1, 3, 6, 12 and 24 h after exposed to phosgene) , 6 rats in each group. Rats in control group were exposed to air for 5 min, while rats in phosgene group were exposed to 8.33 mg/L phosgene for 5 min. The blood samples were collected at 1, 3, 6, 12 and 24 h after phosgene exposure. The blood creatinine (Cr) , urea nitrogen (BUN) and blood gas analysis were detected. HE staining and immunohistochemical staining were performed to observe the expression levels of 8-hydroxy deoxyguanosine and myeloperoxidase. Results: The arterial partial pressure of oxygen and oxygenation index of rats in the phosgene group were significantly lower than those in the control group at 3, 6 and 12 h after exposure (P<0.01) . The lowest points were reached at 6 h, which were (58.67±7.89) mmHg and (202.30±27.20) mmHg, respectively. The Cr and BUN of rats in the phosgene group were significantly higher than those in the control group at 3, 6, 12, and 24 h, and the renal organ coefficients were significantly higher than those in the control group at 3, 6 and 12 h (P<0.01) . HE staining showed that there were more erythrocytes in the glomeruli of rats in the phosgene group, the volume of renal tubular epithelial cells increased, and the cytoplasm was loose and lightly stained. The damage was most obvious at 6 h. The results of immunohistochemical staining showed that the positive expressions of 8-hydroxy deoxyguanosine and myeloperoxidase in the kidney tissue of the phosgene group increased. Conclusion: Hypoxemia and oxidative stress caused by phosgene poisoning may be the cause of renal damage in rats.

Abstract
Magnolia bark is an edible traditional Chinese medicine that has antibacterial activity against Staphylococcus aureus. In the present study, interactions between S. aureus DNA and raw magnolia bark (RMB) and ginger mix-fried magnolia bark (GMB) aqueous extracts were determined via spectroscopic methods. Fluorescence spectroscopy and Stern-Volmer constants showed that S. aureus DNA quenched the fluorescence of the extracts by static quenching. UV-Vis spectroscopy and iodide quenching experiments indicated that the interactions between S. aureus DNA and the fluorescent substances might involve groove binding or electrostatic interactions. In 4', 6-diamidino-2-phenylindole competitive assays, the fluorescence intensity at decreased as the extract amount was increased. This indicates that groove binding is responsible for the fluorescence quenching. The antibacterial activity of GMB aqueous extract treated under light, cold, heat and cycling hot-cold conditions decreased by 13.99, 9.31, 10.89 and 14.40%, respectively, whereas that of RMB aqueous extract treated under the same conditions decreased by 8.91, 14.99, 14.99 and 13.70%, respectively. The results indicate that S. aureus DNA quenches the fluorescence of GMB and RMB aqueous extracts by grooving interactions. Additionally, the antibacterial activities of GMB and RMB extracts are sensitive to light and temperature, respectively.

Abstract
OBJECTIVE To explore the effect of Wei 's triple nine needling on visual acuity and visual field in patients with optic atrophy. METHODS A total of 90 patients with optic atrophy were randomized into an observation group and a control group, 45 cases in each one. Treatment of Wei 's triple nine needling combined with conventional medication were adopted in the observation group, conventional medication was given in the control group. Treatment for 4 weeks was required in both groups. Before treatment and 2, 4 weeks into treatment, the visual acuity and visual field were observed, and the clinical efficacy was evaluated in both groups. RESULTS The total effective rate was 57.8% (26/45) in the observation group, which was superior to 28.9% (13/45) in the control group (P<0.05). After 2-week and 4-week treatment, the visual acuity was improved (P<0.01), the mean defect (MD) of visual field was decreased (P<0.01), the mean sensitivity (MS) of visual field was increased in the observation group (P<0.05, P<0.01). After 2-week and 4-week treatment, the visual acuity and the MD of visual field were improved (P<0.01, P<0.05), while the difference of MS of visual field compared before treatment had no statistical significance in the control group (P>0.05). The improvement of visual acuity, MD and MS of visual field after 2-week and 4-week into treatment in the observation group were superior to those in the control group (P<0.05, P<0.01). CONCLUSION Wei 's triple nine needling can effectively improve the visual acuity and the defect of visual field in patients with optic atrophy.

Abstract
Simple Summary This study highlights the epidemiological, cytogenetic and clinical difference between patients with multiple hit diffuse large B-cell lymphoma in Taiwan and those from western countries. Unlike in the West, the majority of patients with multiple hit lymphoma in Taiwan harbor a BCL6 rearrangement. Almost three in every five BCL6-rearranged double hit lymphoma cases in Taiwan are non-GCB phenotype, indicating, at least in part, that the preferential screening for double hit with BCL6 rearrangement may be a clinically-informative modality for patients with non-GCB phenotype DLBCL in Taiwan. This also suggests the need for a different treatment approach than is obtained in the West where BCL6 double hit lymphomas are seemingly GCB. Consistent with our present findings, mandatory screening for BCL6-rearrangement in suspected DLBCL cases in Taiwan may aid early diagnosis, therapy decision, and clinical outcome forecast. Abstract This study investigated the epidemiological and clinical peculiarities of BCL2 and BCL6 rearrangement in patients with high grade B-cell lymphoma (HGBL) from Taiwan, compared with data from Western countries. Two hundred and eighty-two DLBCL cases from Taipei Medical University-affiliated hospitals (n = 179) and Tri-Service General Hospital (n = 103) were enrolled for this study. From the 282, 47 (16.7%) had MYC translocation; 24 of these harbored concurrent BCL2 and/or BCL6 translocation (double-hit, DH or triple-hit, TH). Twelve DH-HGBL cases had simultaneous MYC and BCL6 translocations, 8 harbored MYC and BCL2 rearrangement, while the remaining 4 patients exhibited TH. Together, 66.7% of DH/TH-HGBL patients were BCL6 rearrangement positive. Among these BCL6-rearranged DH/TH-HGBL patients, only 6 (37.5%) overexpressed MYC and BCL6 proteins simultaneously, indicating that MYC-BCL6 co-overexpression may not be plausible surrogate biomarker for screening BCL6-rearranged DH-HGBL. By the end of year 5, all patients with TH-HGBL, BCL2 DH-HGBL and all but one BCL6 DH-HGBL cases had expired or were lost to follow-up. Progression-free survival (PFS) was longer for the non-DH/TH-HGBL group compared with the DH/TH-HGBL group. While the patients with BCL2 DH-HGBL were lost to follow-up by day 800, their remaining TH-HGBL and BCL6 DH-HGBL peers exhibited very poor PFS, regardless of age strata. More so, patients with BCL6 rearrangement were 5.5-fold more likely associated with extranodal involvement compared with their BCL2-rearranged peers. Moreover, ~60.0% of the BCL6-rearranged DH-HGBL cases were non-GCB, suggesting that including screening for BCL6 rearrangement in patients with the non-GCB phenotype may aid medical decision-making and therapeutic strategy. Contrary to contemporary data from western countries, 2 in every 3 patients with DH/TH-HGBL in Taiwan harbor BCL6 rearrangement. Consistent with present findings, we recommend mandatory screening for BCL6 rearrangement in patients with aggressive HGBL in Taiwan.

Abstract
Objective: To explore the correlation between occupational gasoline exposure and metabolic syndrome (MS) . Methods: In September 2019, a total of 147 occupational gasoline exposure workers from a oil sales company in Beijing were selected as the observation group by using cluster sampling method, 158 people without gasoline exposure from the company were selected as the control group. Occupational health examination were performed to measure body mass, blood pressure and fasting plasma glucose (FPG) , triglycerides (TG) , high-density lipoprotein cholesterol (HDL-C) and other data. General demographic characteristics, occupational history, past medical history and personal history were analyzed either. Results: The levels of systolic blood pressure, diastolic blood pressure, FPG, TG and BMI in the observation group were all higher than those in the control group (P<0.05) . The detection rates of MS, obesity and hypertension in the observation group were all higher than those in the control group (P<0.05) . There were no significant differences in age, gender, working age, drinking, smoking, marital status, HDL-C level, detection rates of abnormal TG and HDL-C between the observation group and the control group (P>0.05) . The odds ratio (OR) of MS in the observation group was 1.988 times that in the control group (P<0.05) . Conclusion: Occupational gasoline exposure is associated with the increasing detection rate of MS.

Abstract
Objective: To explore the role of extracellular histones in the pathogenesis of coal worker's pneumoconiosis (CWP) , the relationship of extracellular histones in plasma with pulmonary fibrosis caused by coal mine dust was analyzed, and the stimulating effect of extracellular histones on fibroblast proliferation was studied. Methods: In May 2019, a total of 220 coal mine dust exposure workers (including coal miners and CWP patients) who visited the occupational disease outpatient department of Peking University Third Hospital from 2012 to 2015 were enrolled in the study. According to the classification of small opacity profusion (SOP) in chest radiograph for pneumoconiosis diagnosis (category 0, 1, 2, 3) , 61 coal miners were in category 0 SOP, 65 coal miners were in category 1 SOP, 56 coal miners were in category 2 SOP and 38 coal miners were in category 3 SOP. The plasma levels of extracellular histone H4 and platelet-derived growth factor (PDGF) were measured by enzyme-linked immunosorbent assay (ELISA) kit. The stimulating effects of CWP patients' plasma and calf thymus histones (CTHs) on fibroblast and the antagonizing effect of anti-H4 antibody were investigated by fibroblast proliferation experiment in vitro. Results: Among the study subjects, there were 195 males (88.6%, 195/220) and 25 females (11.4%, 25/220) , age (55.1±7.2) years, coal mine dust exposure time (16.3±4.4) years. The plasma concentrations of histone H4 in the coal miners with category 0, 1, 2 and 3 SOP were (3.92±1.75) 、(9.84±4.17) 、(14.35±5.52) and (17.83±7.69) μg/ml, respectively. There were significant differences among the four groups (P<0.01) . The plasma level of histone H4 was positively correlated with the plasma level of PDGF in the coal miners (r=0.769, P<0.01) . Compared with healthy control plasma group, the cell proliferation percentages of patients' plasma group (272%±87%) and CTH group (283%±84%) were significantly increased (P<0.05) . Compared with patients' plasma group, the cell proliferation percentage of patients' plasma+anti-H4 antibody group (185%±66%) was significantly decreased (P<0.05) . Compared with CTH group, the cell proliferation percentage of CTH+anti-H4 antibody group (167%±59%) was significantly decreased (P<0.05) . Conclusion: Extracellular histones in plasma are associated with pulmonary fibrosis in patients with CWP. Studies in vitro have shown that extracellular histones can promote proliferation of pulmonary fibroblasts. It is suggested that extracellular histones can be important biomarkers for pulmonary fibrosis caused by coal mine dust.

Abstract
Astragalus membranaceus is the most popular traditional Chinese medicine for managing vital energy deficiency. Its injectable polysaccharide PG2 has been used for relieving cancer-related fatigue, and PG2 has immune-modulatory and anti-inflammatory effects. In this study, we explored the effects of PG2 in lung adenocarcinoma A549 and CL1-2 cells and investigated its anticancer activity, and the results were validated in severe combined immunodeficiency (SCID) mice. Although PG2 did not inhibit the growth of these cells, it dose-dependently suppressed their migration and invasion, accompanied by reduced vimentin and AXL and induced epithelial cadherin (E-cadherin) expression. Regarding the underlying molecular mechanism, PG2 treatment reduced the macrophage migration inhibitory factor (MIF), an inflammatory cytokine that promotes the epithelial-mesenchymal transition and aggressiveness of cancer cells. Consistent with the previous finding that MIF regulates matrix metalloproteinase-13 (MMP-13) and AMP-activated protein kinase (AMPK), treatment with PG2 reduced MMP-13 and activated AMPK in A549 and CL1-2 cells in this study. In SCID mice injected with A549 cells through the tail vein, intraperitoneal injection with PG2 reduced lung and abdominal metastases in parallel with decreased immunohistochemical staining of AXL, vimentin, MMP-13, and MIF in the tumor. Collectively, data revealed a potential application of PG2 in integrative cancer treatment through the suppression of MIF in cancer cells and their aggressiveness.

Abstract
Objective: To evaluate the incidence of deeply infiltrating endometriosis (DIE) among patients of pelvic endometriosis confirmed by pathology and to make analysis of its clinical and pathological characteristics. Methods: From January 1, 2018 to December 31, 2018, clinical data of 240 cases of pelvic endometriosis diagnosed by laparoscopy and pathology hospitalized in Peking University First Hospital were analyzed retrospectively for the characteristics of symptoms, pelvic examination and anatomic distribution of endometriosis foci. Results: (1) Among 240 cases of pelvic endometriosis, 94 were diagnosed with DIE with an incidence of 39.2% (94/240); of them the diagnosis were made preoperatively in 44 cases (46.8%, 44/94). (2) Compared with those without DIE, patients with DIE had higher rates of secondary dysmenorrhea [53.2% (50/94) versus 38.4% (56/146), P=0.033], anal pain [43.6% (41/94) versus 28.1% (41/146), P=0.013], dyspareunea [39.4% (37/94) versus 18.5% (27/146), P=0.001] and frequent bowel movement [33.0% (31/94) versus 15.8%(23/146), P=0.002]. (3) Patients with DIE had higher rates of bad movement of uterus [21.3% (20/94) versus 6.8% (10/146), P=0.001], painful nodularity on uterosacral ligaments [26.6% (25/94) versus 6.2% (9/146), P<0.01], painful nodularity of posterior fornix [19.1% (18/94) versus 4.8% (7/146), P<0.01], blue nodule in vaginal wall [6.4% (6/94) versus 0 (0/146), P=0.003] by pelvic examination compared with those without DIE. (4) Ninety-four patients with DIE had a total of 162 nodules, of those 88 (54.3%, 88/162) located in uterosacral ligaments, 14 (8.6%, 14/162) in the rectum, 7 (4.3%, 7/162) in vaginal wall, 6 (3.7%, 6/162) in ureter, 4 in bladder (2.5%, 4/162), 2 (1.2%, 2/162) in Douglas pouch. Forty-three DIE patients (45.7%, 43/94) had more than one nodules. Patients with DIE had concomitant ovarian endometriosis in 69 cases (73.4%, 69/94), with a total of 103 endometrial cysts. (5) Patients with DIE had a higher rate of obliterated Douglas pouch [76.6% (72/94) versus 19.2% (28/146), P<0.01]. Conclusions: More than one third of patients with pelvic endometriosis have concomitant DIE with a lower rate of preoperative diagnosis. Pelvic pains, bad movement of uterus and painful nodulirity around cervix suggest the presence of DIE.

Abstract
Objective: To analyze the diagnostic value of skeletal muscle biopsy in patients with rhabdomyolysis. Methods: Clinical and pathological data of 26 patients with rhabdomyolysis from January 2002 to December 2018 undergoing muscle biopsy were collected. Results: Eighteen males and 8 females were finally recruited with median age of 6-73 (37.3±19.6) years. The average time from onset to biopsy was 44 days (median course was 30 days). All patients had acute manifestations with muscle pain and/or weakness. Serum creatine kinase was between 1 648-92 660 U/L. Muscle biopsies showed nonspecific changes in 12 cases (a few with type 2 muscle fiber atrophy, slight deposition of lipid droplets), 10 cases with necrotizing myopathy (muscle fiber necrosis and regeneration). Toxic neurogenic damages were seen in 2 cases (type 1 and type 2 angular atrophic muscle fibers with group change), lipid storage disease in 1 case (lipid droplets deposit significantly) and idiopathic inflammatory myopathy in 1 case (muscle fiber necrosis and regeneration, with lymphocyte infiltration). The etiology of non-specific pathological changes included short-term strenuous exercise in 6 patients, poisoning in two, chronic kidney disease in one, viral infection in one, hypothyroidism in one and unknown reason in one. As to patients with necrotizing myopathy, seven were poisoning or drug-related, one with hyperthyroidism, two with unknown reason. Conclusions: Among the numerous causes of rhabdomyolysis, exercise usually links nonspecific skeletal muscle changes and poisoning or drug-related disorders are commonly associated with necrotic myopathy. Rhabdomyolysis induced by primary myopathy is rare.

Abstract
Objective: To observe the changes of extracellular histones and pulmonary microvascular endothelial cells, and study the activating role of extracellular histones to pulmonary microvascular endothelial cells in the pathogenesis of acute respiratory distress syndrome (ARDS) . Methods: The correlation of the severity of acute lung injury with extracellular histones and pulmonary endothelial damage was studied through mice model, and acute lung injury was produced by aspiration of different concentrations of hydrochloric acid (0.01、0.1、0.3 and 0.5 mol/L, 2 ml/kg). Tumor necrosis factor-α (TNF-α), soluble thrombomodulin (sTM) and lung pathological change were measured. The pro-inflammatory role of extracellular histones was tested by injecting calf thymus histones (CTH) or specific anti-H4 antibody through tail vein. The direct activating role of extracellular histones to pulmonary microvascular endothelial cells was studied through pulmonary endothelial model. Results: The extracellular histones in plasma were increased obviously 6h after aspiration of different concentrations of hydrochloric acid in mice. A positive correlation was seen between extracellular histones and concentrations of aspirated hydrochloric acid (r=0.9180, P<0.05). The sTM in plasma also showed a positive correlation with concentrations of aspirated hydrochloric acid (r=0.8701, P<0.05). Merely administering CTH could not only increase TNF-α and sTM in plasma but also cause obvious lung injury, while specific anti-H4 antibody could relieve the inflammation and lung damage caused by CTH. Extracellular histones could directly damage pulmonary endothelial cells to release sTM in pulmonary endothelial model in vitro, while anti-H4 antibody could protect the endothelial cells. Conclusion: Extracellular histones are the key endogenic inflammatory mediators during the pathogenesis of ARDS caused by aspiration of hydrochloric acid, which could promote inflammation by directly activating pulmonary endothelial cells.

Abstract
Objective: To determine the factors affecting distribution and magnitude of antibody detection value in myasthenia gravis (MG). Methods: A total of 406 MG patients diagnosed at Department of Neurology, Peking University First Hospital from May 2015 to November 2017 were included.All of them exhibited muscle fatigue with decreased response in repetitive nerve stimulation test. There were 200 males and 206 females whose ages ranged from 2 to 85 years old. According to clinical classification of MG recommended by Myasthenia Gravis Foundation of America (MGFA), patients assigned to class I to class V included 200,140, 46, 15 and 5 cases, respectively. There were 33 cases of thymic hyperplasia and 63 cases of thymoma confirmed by radiological or pathological findings. Quantile plots and quantile regression model were used to determine the effects of age, gender and MGFA classification, thymus disease on acetylcholine receptors (AChR)antibody, acetylcholinesterase (AChE) antibody, Titin antibody, ryanodine receptor (RyR) antibody and muscle-specific tyrosine kinase (MuSK) antibody detection values detected by enzyme-linked immunosorbent assay (ELISA). Results: MGFA classification had effects on distribution of AChR antibody level. There was a positive correlation between age and AChR antibody level(P<0.05). Negative correlation was found between age and AChE, Titin and RyR antibody level (P<0.05). No significant correlation was shown between any factors and MuSK antibody level(P≥0.05). MGFA classification had a positive correlation with AChR antibody level (P<0.05) and no correlation with other antibody levels (P>0.05). Gender and thymus disease had no correlation with any tested antibody levels (P>0.05). Conclusion: MGFA classification has significant effects on distribution of AChR antibody level. Age and MGFA classification have positive correlation with AChR antibody level.

Abstract
Objectives: To understand the status of studies about influenza economic burden in mainland China and summarize their major results. Methods: The words of influenza, flu, cost, economic, burden, effectiveness, benefit, utility, China, and Chinese, were used as search keywords. Journal papers published during 2000-2018 were searched from Chinese electronic databases (CNKI and Wanfang) and English electronic databases (PubMed, Web of science, EconLit and Cochrane Library). The language of literature was restricted to Chinese and English. A total of 23 effective documents were included, and the descriptive characteristics, research indexes and methods included in the literature were analyzed. The monetary unit used in this review is Chinese Yuan (CNY). Results: The 23 study sites were mainly in the relatively developed and populous regions. The total cost per capita of laboratory-confirmed influenza,of all age-group was reported in 6 literatures, and only 4 literatures reported it in out-patients (range: 768.0-999.9 CNY), Only one study reported this indicator in inpatients (9 832.0 CNY). One literature reported the total cost per capita of influenza-like illness,, which was 205.1 CNY. And one literature reported that the direct medical cost of inpatients per capita in children under 5 years of age was 6 072.0 CNY while two literature reported this index for the elderly over 60 years of age, ranging from 14 250.0 to 19 349.1 CNY. Four articles reported the economic burden of influenza in urban and rural areas, one of which showed that the related expenses of urban influenza inpatients accounted for 31% of the average annual income, while which for the rural flow was 113%. Conclusion: The average economic burden of lab-confirmed influenza case is higher than that of influenza-like illness, and there are differences in outpatient indirect expenses and inpatients direct medical expenses. The direct medical burden for the hospitalized 60-years-and-beyond influenza case group is heavier thar other age group. By region, the influenza associated individual economic burden in rural area is higher than that of urban area..

Abstract
Objective: To understand the characteristics relating to the etiology and complications of hand, foot and mouth disease (HFMD) based on data from the pilot National Sentinel Surveillance (NSS) program so as to explore the feasibility, advantages and disadvantages of the NSS. Methods: Data were extracted from the NSS system, conducted in 11 provinces of China from November 2015 to October 2016. Characteristics regarding the etiology, complications of HFMD and factors related to the positive rates of HFMD specimens were analyzed under the logistic regression method by SPSS 20.0 software. Results: A total of 4 783 specimens were collected, including 3 390 from mild, 1 390 from severe and 3 from death cases. The overall positive rate was 81.43% (3 895/4 783). Other enteroviruses (non EV71/Cox A16 enteroviruses) appeared the major serotype (52.68%, 1 482/2 813) for mild infection of the disease while EV71 was for the severe cases (65.31%, 706/1 081). The serotype spectrum revealed by the pilot NSS was almost identical with the existing surveillance system. Other enteroviruses tended to infect younger children (χ(2)=130.17, P<0.001) than EV71 and Cox A16, in China. The multivariate logistic regression results showed that higher positive rate was associated with specimens which were collected from males, at children' hospitals, in peak seasons, timely and in stools. The positive rates presented downwarding trends with the extension of the onset-sampling interval (χ(2)=14.47, P<0.001 in stool specimen; χ(2)=31.99, P<0.001 in throat swab; χ(2)=24.26, P<0.001 in anal swab). Aseptic meningitis, non-brainstem encephalitis and brainstem encephalitis appeared the top three complications of both EV71-associated and other enteroviruses-associated severe HFMD cases. Conclusions: Factors as gender, season/place/timeliness of specimen collection, and types of hospital all appeared independently influenced the positive rates. NSS seemed feasible to be used as an alternative or supplement tool to the existing surveillance program in China.

Abstract
Objective: To explore the selection method and technology of laparoscopic surgery for gallbladder stones and common bile duct stones(GCBDS). Methods: Data was collected from 318 in-patients of GCBDS at Department of General Surgery,Xuanwu Hospital of Capital Medical University from January 2013 to December 2017, and 298 in-patients acceptedlaparoscopic cholecystectomy(LC) and choledocholithotomy were recruited into final analysis.There were 138 males and 160 females,aged (60.4±18.6)years (range:25-89 years).Retrospective analysis was done on method distribution,effect and safety of laproscopic surgery.Comparisons of basic characters and therapeutic effects were performed betweenlaparoscopic common bile duct exploration (LCBDE) combined with primary closure and T tube drainage(TTD). Results: Among therecruited in-patients,LC combined with common bile duct exploration was performed in 7 cases(2.3%, 7/298), LC combined with LCBDE was performed in 291 cases(97.7%,291/298).There were 133 cases (45.7%,133/291) who treated by LCBDE combined with TTD and 158 cases(54.3%,158/291) who treated by LCBDE combined with primary closure.In LCBDE combined with primary closure group,18 cases (11.4%,18/158)had intraoperative biliary manometry.All patients were followed up for 6 months at least and there no death.Postoperative complications rate was 10.0% (29/291).There were no significant differences in sex ratio,age,American Society of Anesthesiologists score,concomitant diseases and previous abdominal surgery history between LCBDE combined with primary closure and LCBDE combined with TTD group.Patients in LCBDE combined with primary closure group were accompanied with less acute cholangitis than TTD group (43.3% vs.76.7%; χ(2)=9.061, P=0.002).There were no significant differences in the diameter of common bile duct, the number of stones, hospitalization expenses and the incidence of complications between the two groups(all P>0.05).LCBDE combined with primary closure had shorter operation time ((134.2±28.3)minutes vs.(148.3±19.6)minutes; t=-1.830, P=0.011)and post-operative hospitalization time ((5.6±2.6)days vs. (7.2±2.4)days; t=-1.847,P=0.014).Bile duct leakage rate was higher in primary closure group(6.3% vs.0.8%, χ(2)=3.934, P=0.047) and TTD group had higher residual stones rate(6.8% vs.1.3%; χ(2)=6.008, P=0.014). Conclusion: Strategy for treating GCBDS by laparoscopic surgery should be considered preoperative evaluation and intraoperative exploration to select appropriate minimally invasive surgical methods and techniques.

Abstract
Seasonal influenza vaccination is the most effective way to prevent influenza virus infection and its complications. Currently, China has licensed trivalent (IIV3) and quadrivalent inactivated influenza vaccine (IIV4), including split-virus influenza vaccine and subunit vaccine. In most parts of China, influenza vaccine is a category Ⅱ vaccine, which means influenza vaccination is voluntary, and recipients need to pay for it. To strengthen the technical guidance for prevention and control of influenza and the operational research on influenza vaccination in China, the National Immunization Advisory Committee (NIAC), Influenza Vaccine Technical Working Group (TWG), updated the 2014 technical guidelines and compiled the "Technical guidelines for seasonal influenza vaccination in China (2018-2019)" , based on most recent existing scientific evidences. The main updates include: epidemiology and disease burden of influenza, types of influenza vaccines, northern hemisphere influenza vaccination composition for the 2018-2019 season, and, IIV3 and IIV4 vaccines'major immune responses, durability of immunity, immunogenicity, vaccine efficacy, effectiveness, safety, cost-effectiveness and cost-benefit. The recommendations include: Points of Vaccination clinics (PoVs) should provide influenza vaccination to all persons aged 6 months and above who are willing to be vaccinated and do not have contraindications. No preferential recommendation is made for any influenza vaccine product for persons who can accept ≥1 licensed, recommended, and appropriate products. To decrease the risk of severe infections and complications due to influenza virus infection among high risk groups, the recommendations prioritize seasonal influenza vaccination for children aged 6-60 months, adults ≥60 years of age, persons with specific chronic diseases, healthcare workers, the family members and caregivers of infants <6 months of age, and pregnant women or women who plan to pregnant during the influenza season. Children aged 6 months to 8 years old require 2 doses of influenza vaccine administered a minimum of 4 weeks apart during their first season of vaccination for optimal protection. If they were vaccinated in previous influenza season, 1 dose is recommended. People ≥ 9 years old require 1 dose of influenza vaccine. It is recommended that people receive their influenza vaccination by the end of October. Influenza vaccination should be offered as soon as the vaccination is available. Influenza vaccination should continue to be available for those unable to be vaccinated before the end of October during the whole season. Influenza vaccine is also recommended for use in pregnant women during any trimester. These guidelines are intended for CDC members who are working on influenza control and prevention, PoVs members, healthcare workers from the departments of pediatrics, internal medicine, and infectious diseases, and members of maternity and child care institutions at all levels.

Abstract
OBJECTIVES We investigated the incidence of tuberculosis (TB) in patients with newly diagnosed oral cancer and analyzed the risk factors for TB development and mortality in oral cancer patients. MATERIALS AND METHODS We used Taiwan's National Health Insurance Database to determine the incidence of TB and to analyze the risk factors for TB in patients newly diagnosed with oral cancer. From 2000 to 2011, we identified 40,327 oral cancer patients and the same number of subjects from the general population matched for sex, age, and comorbidities at a 1:1 ratio. RESULTS Compared with the matched cohort, oral cancer patients exhibited a higher risk for TB (adjusted hazard ratio (aHR) 2.36, 95% confidence interval (CI) 2.06-2.71). Age ≥ 50 (aHR 1.90, 95% CI 1.57-2.29), being male (aHR 1.98, 95% CI 1.36-2.89), having diabetes mellitus (aHR 1.31, 95% CI 1.05-1.64), alcohol use disorder (aHR 1.42, 95% CI 1.06-1.89), human immunodeficiency virus (HIV) (aHR 8.24, 95% CI 2.05-33.14), chemotherapy (aHR 1.41, 95% CI 1.15-1.72), and radiotherapy for oral cancer (aHR 1.92, 95% CI 1.57-2.36) were identified as independent risk factors for TB in oral cancer patients. Hyperlipidemia was an independent protective factor for TB in oral cancer patients. CONCLUSION Old age, male sex, diabetes mellitus, alcohol use disorder, and HIV were independent risk factors for TB in patients with oral cancer. CLINICAL RELEVANCE High-risk oral cancer patients should be regularly screened for TB, especially those in endemic areas.

Except for a few major cities, influenza vaccine is a category Ⅱ vaccine, which means influenza vaccination is voluntary, and recipients must pay for it. To strengthen the technical guidance for prevention and control of influenza and operational research on influenza vaccination in China, the National Immunization Advisory Committee (NIAC) Influenza Vaccine Technical Working Group (TWG), updated the 2014 technical guidelines and compiled the "Technical guidelines for seasonal influenza vaccination in China (2018-2019)" . The main updates in this version include: epidemiology, disease burden, types of influenza vaccines, northern hemisphere influenza vaccination composition for the 2018-2019 season, IIV3 and IIV4 immune response, durability of immunity, immunogenicity, vaccine efficacy, effectiveness, safety, cost-effectiveness and cost-benefit. The influenza vaccine TWG provided the recommendations for influenza vaccination for the 2018-2019 influenza season based on existing scientific evidence. The recommendations described in this report include the following: Points of Vaccination clinics (PoVs) should provide influenza vaccination to all persons aged 6 months and above who are willing to be vaccinated and do not have contraindications. No preferential recommendation is made for one influenza vaccine product over another for persons for whom more than one licensed, recommended, and appropriate product is available. To decrease the risk of severe infections and complications due to influenza virus infection among high risk groups, the recommendations prioritize seasonal influenza vaccination for children aged 6-59 months, adults ≥60 years of age, persons with specific chronic diseases, healthcare workers, the family members and caregivers of infants <6 months of age, and pregnant women or women who plan to become pregnant during the influenza season. Children aged 6 months through 8 years require 2 doses of influenza vaccine administered a minimum of 4 weeks apart during their first season of vaccination for optimal protection. If they were vaccinated in 2017-2018 influenza season or a prior season, 1 dose is recommended. People more than 8 years old require 1 dose of influenza vaccine. It is recommended that people receive their influenza vaccination by the end of October. Influenza vaccination should be offered as soon as the vaccination is available. For the people unable to be vaccinated before the end of October, influenza vaccination will continue to be offered for the whole season. Influenza vaccine is also recommended for use in pregnant women during any trimester. These guidelines are intended for use by staff members of the Centers for Disease Control and Prevention at all levels who work on influenza control and prevention, PoVs staff members, healthcare workers from the departments of pediatrics, internal medicine, and infectious diseases, and staff members of maternity and child care institutions at all levels.

Abstract
This study aimed to investigate the effect of T cell subsets with different proportions on renal function and blood lipids in patients with preeclampsia (PE). Ninety pregnant women were included in this experiment and classified into 3 groups: group A (30 with severe PE), group B (30 with mild PE) and group C (30 healthy pregnant women). Clinical characteristics were examined. The ratio of T cell subsets in the three groups was detected by flow cytometry. The relationship between PE and T cell subsets was determined. The results showed that no significant difference was found in age or gestational age (P>0.05). The number of CD4+ T cells (CD4 is mainly expressed in helper T cells, referred to as TH) in group A increased significantly compared with group B and group C (P less than 0.05), while the number of CD8+ T cells (CD8+ T cell, also known as cytotoxic T cell (CTL) in group A decreased noticeably in comparison to group C (P less than 0.05). The ratio of CD4+ cell number to CD8+ cell number (TH/CTL) in group A was elevated significantly compared with group B and group C (P less than 0.05). The uric acid (UA) concentration of group A was noticeably elevated compared to group C (P less than 0.05), which differed insignificantly between group B and C (P>0.05). Glomerular filtration rate (GFR) of group A was obviously impaired in comparison to group B and group C (P less than 0.05), which differed insignificantly between group B and C (P>0.05). Total cholesterol (TC) concentrations in group A, C and B were examined. TC concentrations in the former two groups were slightly higher compared to the latter (P less than 0.05), and those in the former two groups were also higher than the normal range (P less than 0.05). Mean triglyceride (TG) concentrations in all 3 groups were above the normal range, and those in group A and B were significantly higher compared to group C (P less than 0.05). TG concentrations differed insignificantly between group B and C (P>0.05). Serum TG, UA and TC in PE patients were positively related to TH/CTL (P less than 0.05). In conclusion, PE is related to T cell subsets, and T cell subsets are closely related to kidney injury and dyslipidemia.

Abstract
Objective: To evaluate the health related quality of life (HRQoL) for severe hand, foot and mouth disease (HFMD) patients with different complications. Methods: A national telephone interview under the EQ-5D proxy2 questionnaire (EQ-SD and EQ-VAS), was conducted to obtain the HRQoL of lab-confirmed severe HFMD patients, aged between six months and five-year-olds from the national communicable disease surveillance system from January 1, 2012 to December 31, 2013. Results: A total of 685 severe HFMD cases were included in the study. A total of 456 (66.6%) of them were males with 75.8% of them younger than three years old. A total of 337 (49.2%) and 407 (59.4%) of the participants reported that they had problems in mobility or daily activities. A total of 569 (83.1%) and 616 (89.9%) of the cases reported having problems in pain/discomfort or anxiety/depression. The average EQ-5D and EQ-VAS scores were 0.58±0.23 and 53.6±25.7, both were positively associated with the duration of illness. Mean quality adjusted life years loss during the HFMD episode for the severe patients was (15.45±13.75) years/1 000 persons. The QALY losses for severe patients with each of below complication were: respiratory diseases (11.17±8.83) years/1 000 persons, aseptic meningitis (13.56±11.99) years/1 000 persons, encephalitis/brainstem encephalitis/acute flaccid paralysis (AFP) (15.31±12.63) years/1 000 persons, Myocarditis (17.28±18.16) years/1 000 persons, pulmonary hemorrhage/pulmonary edema (17.34±14.98) years/1 000 persons, cardiopulmonary failure (25.47±20.53) years/1 000 persons. Among patients with lab confirmed Entero virus A71 (EV71) (16.51±14.48) years/1 000 persons, the QALY loss was seen higher than Coxsackie virus A16 (Cox A16) (13.02±11.45) years/1 000 persons and other Enter virus (14.74±14.22) years/1 000 persons (Z=11.83, P=0.003). Conclusion: The HRQoL loss for severe HFMD patients substantially increased under complications exacerbation and related to the duration of illness.

Abstract
Objective: Through analyzing the surveillance data on typhoid fever and paratyphoid fever in 2015 to understand the related epidemiological features and most possible clustering areas of high incidence. Methods: Individual data was collected from the passive surveillance program and analyzed by descriptive statistic method. Characteristics on seasonal, regional and distribution of the diseases were described. Spatial-temporal clustering characteristics were estimated, under the retrospective space-time method. Results: A total of 8 850 typhoid fever cases were reported from the surveillance system, with incidence rate as 0.65/100 000. The number of paratyphoid fever cases was 2 794, with incidence rate as 0.21/100 000. Both cases of typhoid fever and paratyphoid fever occurred all year round, with high epidemic season from May to October. Most cases involved farmers (39.68%), children (15.89%) and students (12.01%). Children under 5 years showed the highest incidence rate. Retrospective space-time analysis for provinces with high incidence rates would include Yunnan, Guangxi, Guizhou, Hunan and Guangdong, indicating the first and second class clusters were mainly distributed near the bordering adjacent districts and counties among the provinces. Conclusion: In 2015, the prevalence rates of typhoid fever and paratyphoid fever were low, however with regional high prevalence areas. Cross regional transmission existed among provinces with high incidence rates which might be responsible for the clusters to appear in these areas.

Abstract
Objective: To estimate the direct medical cost of severe hand, foot and mouth disease (HFMD) in patients aged less than five years. Methods: A stratified sampling method was used to collect data on severe HFMD cases reported in the National HFMD surveillance database between Jan 1, 2012, and Dec 31, 2013. The sampling was referenced with the national aetiologic distribution of Enterovirus A71 (EV-A71), Coxsackievirus A16 (CV-A16) and other Enteroviruses (OEV) for severe HFMD cases and the included cases were distributed among seven geographic regions (Northeast, North China, Northwest, Central China, Southwest, East China and South China). A nationwide telephone interview using a structured questionnaire was conducted to obtain the direct medical cost and any complications that occurred in patients during the outbreak of laboratory-confirmed HFMD. After excluding the cases who could not recall their medical expenses or complications, a total of 685 cases were included in the analysis. Kruskal-Wallis H test was used to analyze the differences among patients who reported different complications. Multiple linear regression with bootstrap analysis of 500 replicates was used to explore the factors that influenced the direct medical costs. Results: Of 685 patients analyzed, 456 (66.6%) were male and 229 (33.4%) were female. The direct medical costs P50 (P25, P75) were 14 250 (10 301, 20 600) Yuan. In total, 127 (18.5%) patients were diagnosed with severe HFMD patients with respiratory disease, 38 (5.5%) patients were diagnosed with aseptic meningitis, and 378 (55.2%) with encephalitis/brainstem encephalitis/acute flaccid paralysis. Furthermore, 53 (18.5%) patients were diagnosed with myocarditis, 39 (5.7%) with pulmonary hemorrhage/pulmonary edema and 50 (7.3%) with cardiopulmonary failure. The median (interquartile range) direct medical costs were 12 360 (7 313, 16 480) Yuan for severe HFMD patients with respiratory disease, 13 803 (9 064, 19 930) Yuan for aseptic meningitis, 14 438 (11 000, 20 015) Yuan for encephalitis/brainstem encephalitis/acute flaccid paralysis, 14 800 (8 500, 21 218) Yuan for myocarditis, 20 600 (12 500, 31 130) Yuan for pulmonary hemorrhage/pulmonary edema, and 20 043 (12 772, 28 840) Yuan for cardiopulmonary failure (H=17.70, P<0.001). The results of multiple linear regression with bootstrap analysis revealed that the direct medical cost for severe HFMD patients from Central China was 7 881 (95% CI: 3 814-11 949) Yuan higher than that of North China; severe HFMD patients diagnosed with OEV had direct medical costs of 1 987 (95%CI: 206-3 769) Yuan less those associated with EV-A71; severe HFMD patients whose duration of illness was ≥21 d had 20 480 (95% CI: 10 985- 29 974) Yuan higher direct medical costs those whose illness lasted ≤5 d; the direct medical costs for severe HFMD patients with pulmonary hemorrhage/pulmonary edema and cardiopulmonary failure were 7 874 (95%CI: 3 723-12 026) and 9 855 (95% CI: 328- 19 382) Yuan higher, respectively, than that associated with respiratory disease. Conclusion: The direct medical costs associated with severe HFMD were found to be substantial. The total cost was affected by the duration of the illness and the severity of any complications.

Abstract
Objective: To investigate the clinical severity, etiological classification and risk factors of severe cases with hand, foot and mouth disease (HFMD). Methods: A total of 1 489 records on severe and fatal HFMD cases reported to the national pilot surveillance system of HFMD were used to analyze the demographic, medical treatment, etiological classification of the cases. Treatment outcome related risk factors were also studied with multi-variable stepwise logistic regression method. Results: Seven out of the 1 489 severe HFMD cases died of this disease. A total of 960 (72.9%) were under three years old and 62.9% were male and most of the cases (937, 62.9%) resided in rural areas. Among all the cases, 494 (33.2%) went to seek the first medical assistance at the institutions of village or township level. Durations between disease onset and first medical attendance, being diagnosed as the disease or diagnosed as severe cases were 0(0-1) d, 1 (0-2) d and 2 (1-4) d, respectively. In total, 773 (51.9%) of the severe HFMD cases were diagnosed as with aseptic meningitis, 260 (17.5%) with brainstem encephalitis, 377 (25.3%) with non-brainstem encephalitis, 6 (0.4%) with encephalomyelitis, 1 (0.1%) with acute flaccid paralysis, 4 (0.3%) with pulmonary hemorrhage/pulmonary edema and 68 (4.6%) with cardiopulmonary failure. Of the etiologically diagnosed 1 217 severe and fatal HFMD cases, 642 (52.8%) were with EV71, other enterovirus 261 (21.5%), Cox A16 36 (3.0%), 1 (0.1%) with both EV71 and Cox A16. However, 277 (22.8%) showed negative on any pathogenic virus. Complication (Z=3.15, P=0.002) and duration between onset and diagnosed as severe cases (Z=3.95, P<0.001) were shown as key factors related to treatment outcomes. Conclusions: Most severe HFMD cases appeared in boys, especially living in the rural areas. Frequently seen complications would include aseptic meningitis, non-brainstem encephalitis and brainstem encephalitis. EV71 was the dominant etiology for severe and fatal cases. Early diagnosis and complication control were crucial, related to the treatment outcome of HFMD.

Abstract
OBJECTIVE To report thigh muscle magnetic resonance imaging (MRI) tests of four Chinese patients with dystrophinopathy with edema changes in adductor longus muscles that mimics adductor enthesopathy. METHODS Four boys, who were from four unrelated families and aged from 5 to 11 years, were investigated because of the clinical manifestations including myalgia or muscle weakness or the incidental findings of elevated serum creatine kinase levels, and were diagnosed with dystrophinopathy by gene test of Duchenne muscular dystrophy (DMD). Their creatine kinase levels were increased from 4 087 IU/L to 32 700 IU/L (Normal range: 75-175 IU/L). The muscle biopsy of three patients all demonstrated a dystrophic pattern including necrosis, regeneration, hypertrophy, atrophy and connective tissue proliferation, with different proportions of dystrophin-negative muscle fibers. The gene test of DMD showed an out-frame deletion of exons in three of the four patients, involving either exons 45 or exons 49-52 deletion or exon 62 duplication, and c.2665 C>T with nonsense mutation in the other one. Muscle MRI tests of the bilateral thighs were performed with T1 weighed sequence and slow tau inversion recovery sequence. The degree of fatty infiltration changes was scored. RESULTS MRI of the thigh muscles showed mild to severe fatty infiltration changes in T1 weighed sequence with the total scores from 2 to 13.The most severe fatty infiltration changes were in the long head of biceps femoris and adductor magnus. Obvious hyperintensities appeared mainly in the adductor longus muscles on slow tau inversion recovery (STIR) images in all the patients without any abnormal signals in the attachment of the ligament, indicating edema changes of the adductor longus muscles which mimiced adductor enthesopathy. Two of the four patients presented with edema changes in the bilateral adductor longus muscles, while the other two were with only unilateral changes. Furthermore, other thigh muscles, including adductor magnus, semitendinosus, sartorius and rectus femoris muscles, could also have mild edema changes in two of the four patients. CONCLUSION Dystrophinopathy can manifest as edema changes in the adductor longus muscles in thigh muscle MRI tests, which is a typical lesion in adductor enthesopathy. The adductor longus muscles in the dystrophinopathy patients may be easy to be impaired due to traction injury during sports.

Abstract
OBJECTIVE To describe a method based on analysis of the histogram of intensity values produced from the magnetic resonance imaging (MRI) for quantifying the degree of fatty infiltration. METHODS The study included 25 patients with dystrophinopathy. All the subjects underwent muscle MRI test at thigh level. The histogram M values of 250 muscles adjusted for subcutaneous fat, representing the degree of fatty infiltration, were compared with the expert visual reading using the modified Mercuri scale. RESULTS There was a significant positive correlation between the histogram M values and the scores of visual reading (r=0.854, P<0.001). The distinct pattern of muscle involvement detected in the patients with dystrophinopathy in our study of histogram M values was similar to that of visual reading and results in literature. The histogram M values had stronger correlations with the clinical data than the scores of visual reading as follows: the correlations with age (r=0.730, P<0.001) and (r=0.753, P<0.001); with strength of knee extensor (r=-0.468, P=0.024) and (r=-0.460, P=0.027) respectively. Meanwhile, the histogram M values analysis had better repeatability than visual reading with the interclass correlation coefficient was 0.998 (95% CI: 0.997-0.998, P<0.001) and 0.958 (95% CI: 0.946-0.967, P<0.001) respectively. CONCLUSION Histogram M values analysis of MRI with the advantages of repeatability and objectivity can be used to evaluate the degree of muscle fatty infiltration.

Abstract
A series of HSP70 promoter deletion constructs was established. Analysis of beta-glucuronidase activities from the promoter deletion constructs in transient expression assays identified a cis-element, located from -493 to -308 bp upstream of the ATG start site. This element was designated as HS185 and has a crucial role in HSP70 promoter activity. HS185 has some characteristics of a miniature inverted-repeat transposable element (MITE), such as terminal inverted repeats (TIRs) (GGTCCCACA) and a putative target site duplication. There are 362 copies of homologous sequences of HS185 in the rice genome, which are preferentially distributed to non-coding regions. Based on these sequence features, we propose that HS185 is an uncharacterized rice MITE, possibly derived from the rice transposon Mutator-like element VIII family. Further transient expression assays showed that HS185 inhibited the enhancer activity of the cauliflower mosaic virus 35S promoter. These results demonstrate that not only is HS185 necessary for HSP70 promoter activity, but it also has a functional role as an insulator. This study explored new regulatory functions of non-coding repeat sequences in rice.

Abstract
The elytra of longhorn beetles Tmesisternus isabellae show iridescent golden coloration which stems from long and flat scales imbricated densely on the elytral surface. The scales are able to change coloration from golden in the dry state to red in the wet state with water absorption. Structural characterizations revealed that the iridescent coloration of scales originates from a multilayer in the scale interior. Measurements on both water contact angle and chemical composition indicated that scales are hydrophilic. The change in scale coloration to red in the wet state is due to both the swelling of the multilayer period and water infiltration. The unraveled structural color change and its strategy may not only help us get insight into the biological functionality of structural coloration but also inspire the designs of artificial photonic devices.

Abstract
The objective was to investigate the effect of phytohemagglutinin (PHA) on the fusion of mammary gland epithelial (MGE) cells into enucleated oocytes in goats. The toxicity of PHA was evaluated by testing its effect on the development of parthenogenetic caprine oocytes. The effective dose and duration of PHA treatment (100 microg/mL, 20 min incubation) was selected and used to compare fusion efficiency and embryo development following nuclear transfer. Two electrofusion protocols, chamber fusion (CF) and pressurized microelectrode fusion (pMEF), were also compared, when couplets were treated with and without PHA (100 microg/mL, 20 min). Fusion rate of couplets increased from 52.8 to 74.0% for the CF protocol (P<0.05), but was not significantly different for the pMEF protocol (72.7% vs. 78.1%) after PHA treatment. There were no significant differences between treated group and control in rates of subsequent cleavage or blastocyst development. Following transfer of the cloned blastocysts derived from the PHA-treated group and the control group into synchronized recipients, pregnancy rates (Day 30) were not significantly different between treated group and control (28.6% vs. 25.0%). However, all recipients aborted within 120d, microsatellite DNA analyses confirmed that the aborted fetuses were genetically identical to the donor goat. In conclusion, the fusion rate of caprine MGE cell couplets was improved by pre-incubating couplets in medium containing 100 microg/mL PHA prior to electrical pulsing, and embryos derived from PHA treatment established early pregnancies.

Abstract
Consumption of food crops contaminated with heavy metals is a major food chain route for human exposure. We studied the health risks of heavy metals in contaminated food crops irrigated with wastewater. Results indicate that there is a substantial buildup of heavy metals in wastewater-irrigated soils, collected from Beijing, China. Heavy metal concentrations in plants grown in wastewater-irrigated soils were significantly higher (P<or=0.001) than in plants grown in the reference soil, and exceeded the permissible limits set by the State Environmental Protection Administration (SEPA) in China and the World Health Organization (WHO). Furthermore, this study highlights that both adults and children consuming food crops grown in wastewater-irrigated soils ingest significant amount of the metals studied. However, health risk index values of less than 1 indicate a relative absence of health risks associated with the ingestion of contaminated vegetables.

Abstract
As the second most widely cultivated cotton, Gossypium barbadense is well known for its superior fiber properties and its high levels of resistance to Fusarium and Verticillium wilts. To enhance our ability to exploit these properties in breeding programs, we constructed the first bacterial artificial chromosome (BAC) library for this species. The library contains 167 424 clones (49 920 BamHI and 117 504 HindIII clones), with an estimated average insert size of 130 kb. About 94.0% of the clones had inserts over 100 kb, and the empty clones accounted for less than 4.0%. Contamination of the library with chloroplast clones was very low (0.2%). Screening the library with locus-specific probes showed that BAC clones represent 6.5-fold genome equivalents. This high-quality library provides an additional asset with which to exploit genetic variation for cotton improvement.

Abstract
BACKGROUND To develop an ELISA method using Herpesvirus hominis type 4 (EBV) IgG/Zebra as capture antigen for large population screening. METHODS The ELISA method used purified ZEBRA antigen to detect the IgG/ZEBRA antibody from serum in nasopharyngeal carcinoma (NPC) and normal healthy subjects. RESULTS Of 288 NPC sera, 262 were detected positive, the sensitivity was 91%, while 5 of 96 normal sera were detected positive, the specificity was 94.8% and the results of NPC group and healthy group displayed significant difference (P less than 0.001). IgA/VCA, IgA/EA, IgG/EA in immunoenzyme methods and ZEBRA ELISA were compared during the NPC screening in two cities: Huizhou, Guangdong and Guiping, Guangxi, 5463 and 2017 samples respectively were tested and 5 earlier NPC patients were found. CONCLUSION The results indicate that this method has high specificity and sensitivity, and can be used for large population screening to assist early phase NPC diagnosis.

Abstract
In this study, batch experiments were conducted to investigate the inhibitory effects of NaCl on H2 production from glucose by anaerobic mixed cultures. Experimental results demonstrate that NaCl concentration had significant inhibitory effects on glucose degradation, cumulative H2 production, specific H2 production rate, H2 yield and the distribution of aqueous products. The specific H2 production rate had a negative correlation with NaCl concentrations. The NaCl concentrations, at which the specific H2 production rate and H2 yield were reduced by 50%, were estimated as 209 mM and 443 mM, respectively.

Abstract
AIM: To investigate the effect of c9,t11-conjugated linoleic acid (c9,t11-CLA) on the invasion of human gastric carcinoma cell line and its possible mechanism of preventing metastasis.
METHODS: Using reconstituted basement membrane invasion, chemotaxis, adhesion, PAGE substrate zymography and RT-PCR assays, we analyzed the abilities of invasion, direct migration, adhesion of intracellular matrix, as well as the activity of type IV collagenase and expression of tissue inhibitor of metalloproteinase (TIMP)-1 and TIMP-2 mRNA in SGC-7901 cells which were treated with gradually increased concentrations (25, 50, 100 and 200 μmol/L) of c9,t11-CLA for 24 h.
RESULTS: At the concentrations of 200 μmol/L, 100 μmol/L and 50 μmol/L, c9,t11-CLA suppressed the invasion of SGC-7901 cells into the reconstituted basement membrane by 53.7%, 40.9% and 29.3%, respectively, in comparison with the negative control. Only in the 200 μmol/L c9,t11-CLA group, the chemotaxis of SGC-7901 cells was inhibited by 16.0% in comparision with the negative control. C9,t11-CLA also could inhibit the adhesion of SGC-7901 cells to laminin, fibronectin and Matrigel, increase the expression of TIMP-1 and TIMP-2 mRNA, and reduce type IV collagenase activities in the serum-free medium supernatant of SGC-7901 cells.
CONCLUSION: c9,t11-CLA can inhibit the invasion of SGC-7901 cells at multiple procedures in tumor metastasis cascade, which may be associated with the induction of TIMP-1 and TIMP-2 mRNA expression.

Abstract
AIM: To explore the inhibition of conjugated linoleic acid isomers in different purity (75% purity c9, t11-, 98% purity c9, t11- and 98% purity t10,c12-CLA) on the formation of forestomach neoplasm and cheopreventive mechanisms.
METHODS: Forestomach neoplasm model induced by B (a) P in KunMing mice was established. The numbers of tumor and diameter of each tumor in forestomach were counted; the mice plasma malondialdehyde (MDA) were measured by TBARS assay; TUNEL assay was used to analyze the apoptosis in forestomach neoplasia and the expression of MEK-1, ERK-1, MKP-1 protein in forestomach neoplasm were studied by Western Blotting assay.
RESULTS: The incidence of neoplasm in B (a) P group, 75% purity c9,t11-CLA group, 98% purity c9,t11-CLA group and 98% purity t10,c12-CLA group was 100%, 75.0% (P > 0.05), 69.2% (P < 0.05) and 53.8% (P < 0.05) respectively and the effect of two CLA isomers in 98% purity on forestomach neoplasia was significant; CLA showed no influence on the average tumor numbers in tumor-bearing mouse, but significantly decreased the tumor size, the tumor average diameter of mice in 75% purity c9,t11-CLA group, 98% purity c9,t11-CLA group and 98% purity t10,c12-CLA group was 0.157 ± 0.047 cm, 0.127 ± 0.038 cm and 0.128 ± 0.077 cm (P < 0.05) and 0.216 ± 0.088 cm in B (a) P group; CLA could also significantly increase the apoptosis cell numbers by 144.00 ± 20.31, 153.75 ± 23.25, 157.25 ± 15.95 (P < 0.05) in 75% purity c9,t11-CLA group, 98% purity c9,t11-CLA group and 98% purity t10,c12-CLA group (30.88 ± 3.72 in BP group); but there were no significant differences between the effects of 75% purity c9,t11-CLA and two isomers in 98% purity on tumor size and apoptotic cell numbers; the plasma levels of MDA in were increased by 75% purity c9,t11-CLA, 98% purity c9,t11-CLA and 98% purity t10,c12-CLA. The 75% purity c9,t11-CLA showed stronger inhibition; CLA could also inhibit the expression of ERK-1 protein and promote the expression of MKP-1 protein, however no influence of CLA on MEK-1 protein was observed.
CONCLUSION: Two isomers in 98% purity show stronger inhibition on carcinogenesis. However, the inhibitory mechanisms of CLA on carcinogenesis is complicated, which may be due to the increased mice plasma MDA, the inducing apoptosis in tumor tissues. And the effect of CLA on the expression of ERK-1 and MKP-1 may be one of the mechanisms of the inhibition of CLA on the tumor.
