Abstract
Objective: To investigate the efficacy of laparoscopic sleeve gastrectomy (LSG) in morbidly obese patients aged 10 to 21 years. Methods: We conducted a retrospective analysis of clinical data from 89 out of 200 patients who underwent LSG at the Gastrointestinal Surgery/Weight Loss Center of the First Affiliated Hospital of Jinan University between January 2015 and December 2020. The primary outcome measures were the completion rate of LSG, the incidence of perioperative complications, and weight-related indicators 3, 6, 12, and ≥24 months postoperatively. Additionally, we compared glucose metabolism, lipid metabolism, vitamin levels, liver function, and other relevant biochemical variables before and after surgery. Normally distributed continuous data are presented as x±s. Because the numbers of patients at each follow-up time point were not identical with the number of patients in the study cohort preoperatively, independent sample t-tests were used for intergroup comparisons. Non-normally distributed continuous data are presented as M(Q1, Q3), and Mann-Whitney U tests were used for intergroup comparisons. Results: Among the 89 patients, 35 were male (39.3%), the mean age was (18±2) years, and mean body mass index (BMI) 38.5±4.8 kg/m²; 37 of the patients having a BMI greater than 40 kg/m². Additionally, 63 patients (70.8%) had fatty livers, 34 (38.2%) hyperuricemia, 31(34.8%) sleep apnea syndrome, 20 (22.4%) gastroesophageal reflux, eight (8.9%) type 2 diabetes, and two (2.2%) hypertension. All 89 patients underwent LSG surgery successfully, with no conversions to open surgery. During the perioperative period, there were no cases of major bleeding, gastric leakage, or infections. Notable postoperative symptoms included nausea, vomiting, and pain, most of which improved by the second postoperative day. BMI values 3, 6, and 12 months postoperatively had decreased to 31.5±5.8 kg/m², 28.6±4.3 kg/m², and 26.3±4.4 kg/m², respectively. All of these BMI values differed significantly from preoperative values (all P<0.05). At 12 and ≥24 months postoperatively, the percentages of total weight loss were (31.3±9.3)% and (33.1±10.5)%, respectively, both differing significantly from 3 months postoperatively (20.5±5.1)% (all P<0.05). The percentages of excess weight loss at 12 and ≥24 months postoperatively were 91% (70%, 113%) and 95% (74%, 118%) , respectively, both differing significantly from the percentage of total weight loss 3 months postoperatively (56% [45%, 72%]) (both P<0.05). Alanine transaminase and aspartate transaminase serum concentrations decreased from preoperative values of 44.4 (25.5, 100.5) U/L and 29.0 (9.5, 48.0) U/L to 14.0 (10.8, 18.3) U/L and 13.0 (10.5, 17.3) U/L, respectively, ≥24 months postoperatively. Hemoglobin A1c decreased from 5.6 (5.3, 5.8)% preoperatively to ≥24 months postoperatively 5.3 (5.0, 5.4)%. High-density lipoprotein increased from 1.0 (0.9, 1.2) mmol/L preoperatively to 1.4 (1.1, 1.6) mmol/L ≥24 months postoperatively. Vitamin B12 decreased from 350.0 (256.8, 441.3) μg/L preoperative to 230.3(195.4, 263.9) μg/L ≥24 months postoperatively. All differed significantly from preoperative values (all P<0.05). Conclusion: LSG has favorable efficacy in morbidly obese patients aged 10 to 21 years. However, further confirmation is required through long-term, multicenter, randomized, controlled trials.

Abstract
China currently has the largest population of overweight and obese individuals globally. Bariatric surgery is by far the most effective approach to address obesity and associated metabolic conditions. To manage the significant growth of obesity, China's bariatric and metabolic surgery has assumed a pivotal role. Despite a delayed start compared to other nations, China has made significant progress in bariatric metabolic surgery over the past two decades. Presently, the annual number of surgeries ranks ahead worldwide. However, the proportion of eligible obese patients undergoing bariatric surgery in China remains lower than global averages. Looking ahead, China's bariatric metabolic surgery field offers ample room for growth and improvement. This paper aims to highlight the achievements in bariatric and metabolic surgery within China while also addressing challenges, such as the high proportion of laparoscopic sleeve gastrectomy, adherence to operation standards and guidelines, postoperative management and loss of follow-up, and quality control of database. By analyzing the current landscape and challenges, it is anticipated that China's bariatric metabolic surgery will continue to make remarkable progress in the future, bolstered by the collective dedication of the medical community.

Abstract
Obesity poses a serious threat to human health, and although bariatric surgery has been proven effective treatment for morbidly obese patients, its surgical risks and high medical costs limit its clinical application and popularity. Endoscopic sleeve gastroplasty (ESG), as a relatively new endoscopic surgery technique for weight loss, has satisfactory weight loss effects compared to laparoscopic sleeve gastrectomy and lifestyle interventions, while preserving the normal structure of the stomach. Its weight loss effects and safety have been validated in multicenter studies abroad. Although, ESG has not yet been widely performed in China, with the gradual maturity of this technique, its prospects are worth attention in the field of weight loss. In the future, large-scale, long-term, multi-center studies are urgently needed in China to clarify the long-term effects, remission of comorbidities, and occurrence of complications of ESG surgery in obese and metabolic disease patients.

Abstract
Health damage including chronic disease caused by air pollution have attracted increasing attention. With the acceleration of industrialization and urbanization, the emission of air pollutants has increased, and its association with chronic diseases has become a research trending topic. Cardiovascular disease, cancer, diabetes, and chronic respiratory disease are the major chronic diseases, causing about 86.6% of the total deaths in China. The prevention and control of chronic diseases, especially the etiologic prevention, is a major public health issue related to national health. This article summarizes the recent progress in research of association of indoor and outdoor air pollution with all-cause mortality, the deaths and disease burden of four major chronic diseases, i.e. cardiovascular disease, cancer, diabetes, and chronic respiratory disease, and puts forward suggestions for the reduction of the burden caused by chronic diseases due to air pollution to provide a theoretical foundation to revise air quality standards in China.

Abstract
Cardiovascular disease (CVD) is the leading cause of mortality and healthy life expectancy loss, ranking first in causing the global burden of disease. In addition to the traditional CVD risk factors, such as hypertension and diabetes, environmental chemical pollutants may also play a role in the development of CVD. This paper summarizes the evidence regarding the relation of exposures to metal or metalloid and persistent organic pollutants with risk for CVD and introduces the research progress in the relation between the exposures to two environmental chemical pollutants and CVD risk. The study aims to provide scientific evidence for the effective prevention of CVD through the management of chemical pollutants in environment.

Abstract
Carotenoids are naturally occurring pigments that are widely distributed in algae, fungi, bacteria, and plants. Carotenoids play a significant role in the food, feed, cosmetic, nutraceutical, and pharmaceutical industries. These pigments are effectively considered as a health-promoting compounds, which are widely used in our daily diet to reduce the risk of chronic diseases such as cardiovascular diseases, cancer, acute lung injury, cataracts, neural disorders, etc. In this context, this review paper demonstrates the synthesis of carotenoids and their potential application in the food and pharmaceutical industries. However, the demand for carotenoid production is increasing overtime, and the extraction and production are expensive and technically challenging. The recent developments in carotenoid biosynthesis, and key challenges, bottlenecks, and future perspectives were also discussed to enhance the circular bioeconomy.

Abstract
Due to the complexity and heterogeneity of obesity, the diagnosis and treatment of obesity vary greatly. Five to 10 percent of body weight can be lost through lifestyle modifications, nutritional and behavioral counseling, and the use of approved weight reduction medicines for obesity and diabetes; however, these non-surgical treatments are not effective for all patients. Compared to medical therapy, bariatric surgery is associated with higher rates of type 2 diabetes remission, lower mortality from vascular complications, and long-term, sustained weight loss. With the advent of precision medicine in surgical therapy, bariatric surgeons' fundamental understanding of laparoscopic Roux-en-Y gastric bypass surgery has evolved in recent years. The objective of surgery has shifted from short-term weight loss to the safe and successful long-term management of patient weight and comorbidities. In laparoscopic Roux-en-Y gastric bypass surgery, the concept of precision bariatric and metabolic surgery is mainly reflected in three aspects: accurate preoperative assessment, precise intraoperative operation, and comprehensive postoperative management. A new direction for the future development of precision laparoscopic Roux-en-Y gastric bypass surgery and obesity metabolic surgery is to formulate precise and individualized surgical treatment plans for patients and to use artificial intelligence and big data technology to improve the standardization of specialist data.

Abstract
Objective: To report the clinical characteristics and treatment courses of pneumatosis cystoides intestinalis(PCI) after lung transplantation(LT). Methods: We included all cases of PCI after LT from March 2017 to June 2021 in China-Japan Friendship Hospital. In addition to our cases, we searched literatures published in Chinese and English languages using China National Knowledge Infrastructure (CNKI), Wanfang Data and PubMed/MEDLINE with the search terms"pneumatosis intestinalis"and"lung transplantation". The clinical characteristics and treatment courses of all cases were summarized and analyzed. Results: Three cases of PCI occurred after LT in this study, with an incidence of 0.804% (3/373). Thirteen related literatures were retrieved, with 51 cases enrolled. The median age of the 54 patients was 55.4 years (22-79 years), with 33 males and 21 females. 64.81% (35/54) of the 54 patients underwent LT for interstitial lung disease and 90.74% (49/54) underwent bilateral LT. Twenty-two cases(40.7%) were asymptomatic when PCI occurred. Thirty-eight cases (38/54,70.37%)had involvement of ascending colon, and 35 cases(35/54,64.81%)had involvement of transverse colon. Forty-three cases(43/54, 79.63%) were treated conservatively. The average interval between transplantation and PCI was 210 (5-2 495) days. Conclusion: PCI is a rare complication after lung transplantation, most often occurring in the colon. Most patients were asymptomatic and could improve by conservative treatments.

Abstract
Coal is one of the major fuels, which brings huge energy and economic benefits to global industry and daily life. large amounts of coal dust produced in the process of coal mining and transportation, which seriously threatens the health of related workers. Productive coal dust exposure not only directly leads to respiratory diseases, but also may cause health damage to various systems throughout the body. Numerous studies have shown that coal dust exposure is closely associated with decreased lung function, coal worker's pneumoconiosis, chronic obstructive pulmonary disease, lung cancer, and cardiovascular diseases, and the severity of diseases is affected by coal rank, coal dust concentration, cumulative dust exposure, coal dust composition, and individual lifestyle, etc. The article comprehensively summarized the progress of the epidemiological studies on the health hazards of coal miners from coal dust exposure, in order to provide clues for further researches on health damage and protect the health of the occupational population.

Abstract
Objective: To explore the association between occupational noise exposure and cardiovascular disease (CVD) risk in a large Chinese population. Methods: In December 2019, the study included 21412 retired participants from the Dongfeng-Tongji Cohort Study at baseline from September 2008 to June 2010, occupational noise exposure was evaluated through workplace noise level and/or the job titles. In a subsample of 8931 subjects, bilateral hearing loss was defined as a pure-tone mean of 25 dB or higher at 0.5, 1 , 2, and 4 kHz in both ears. Logistic regression models were used to explore the association of occupational noise exposure, bilateral hearing loss with 10-year CVD risk. Results: Compared with participants without occupational noise exposure, the 10-year CVD risk was significantly higher for noise exposure duration ≥20 years (OR=1.20, 95%CI:1.01-1.41 , P=0.001) after adjusting for potential confounders. In the sex-specific analysis, the association was only statistically significant in males (OR=2.34, 95%CI: 1.18-4.66, P<0.001) , but not in females (OR=1.15, 95%CI:0.97-1.37, P=0.153). In the subsample analyses, bilateral hearing loss, which was an indicator for exposure to loud noise, was also associated with a higher risk of 10-year CVD (OR= 1.17, 95% CI:1.05-1.44, P <0.001) , especially for participants who were males (OR =1.24, 95% CI:1.07-2.30, P<0.001) , aged equal and over 60 years old (OR=2.30, 95%CI: 1.84-2.88, P<0.001) , and exposed to occupational noise (OR=1.66, 95%CI: 1.02-2.70, P=0.001). Conclusion: Occupational noise exposure may be a risk factor for CVD.

Abstract
Lymphoma after solid organ transplantation is one of the manifestations of post-transplant lymphoproliferative disorders(PTLD). Here we reported a 39-year-old male patient presented with intermittent fever, markedly elevated level of peripheral blood lymphocytes and lactate dehydrogenase(LDH), rapid decrease in hemoglobin and platelet count ten months after bilateral lung transplantation. After systematic evaluation, the patient excluded infectious diseases. Positron emission tomography-computed tomography (PET/CT) revealed diffuse increasing of standard uptake value in bones throughout the body. The bone marrow aspiration, flow cytometric analysis and histopathology confirmed the diagnosis of diffuse large B-cell lymphoma (DLBCL) with negative Epstein-Barr virus-encoded small RNA (EBER) hybridization in situ. Meanwhile, complicated hemophagocytic lymphohistiocytosis was also diagnosed in the patient based on hypertriglyceridemia, abnormally elevated level of serum ferritin and solvable CD25 (sCD25). Treatment regimen included reduction of immunosuppression, anti-CD20 antibody (CD20+ B cell inhibitor, rituximab) and etoposide. Repeated PET/CT and bone marrow biopsy showed complete remission of lymphoma after 4 months of therapy.

Abstract
Abstract
Background
The association between international normalized-ratio (INR) and long-term prognosis among patients with coronary artery disease (CAD) without atrial fibrillation (AF) or anticoagulant therapy was still unclear. We analyzed the association of INR levels and long-term mortality in a large cohort of CAD patients without atrial fibrillation or using of anticoagulant drugs.
Method
We obtained data from 44,662 patients who were diagnosed with CAD and had follow-up information from January 2008 to December 2018. The patients were divided into 4 groups (Quartile 1: INR ≤0.96; Quartile2: 0.961.06). The main endpoint was long-term all-cause death. Kaplan-Meier curve analysis and Cox proportional hazards models were used to investigate the association between quartiles of INR levels and long-term all-cause mortality.
Result
During a median follow-up of 5.25 years, 5,613 (12.57%) patients died. We observed a non-linear shaped association between INR levels and long-term all-cause mortality. Patients in high INR level (Quartile4: INR >1.06) showed a significantly higher long-term mortality than other groups (Quartile2 or 3 or 4), (Compared with Quartile 1, Quartile 2 [0.961.06], aHR=1.33, 95% CI: 1.22–1.45, P<0.05).
Conclusion
Our study demonstrates high levels of INR were associated with an increased risk of all-cause mortality.

Abstract
Abstract
Background
The association of recovered acute kidney injury (AKI) with mortality was controversial. Our study aims to investigate the impact of recovered AKI on mortality in patients following coronary angiography (CAG).
Methods
Our study retrospectively enrolled 3,970 patients with pre-operative serum p creatinine (Scr) and twice measurements within 48hours after procedure. Recovered AKI defined as the diagnosis of AKI (Scr >0.3 mg/dL or >50% from the baseline level) on day 1 when Scr failed to meet the criteria for AKI on the day 2. Maintained AKI was defined as AKI not meeting the definition for recovered AKI. The primary outcome was 1-year all-cause mortality. Multivariable logistic regression was used to assess the association between recovered AKI and 1-year mortality.
Results
Among 3,970 participants, 861 (21.7%) occurred AKI, of whom 128 (14.9%) was recovered AKI and 733 (85.1%) was maintained AKI. 312 (7.9%) patients died within 1-year after admission. After multivariable analysis, recovered AKI was not associated with higher 1-year mortality (adjusted odds ratio [aOR], 1.37; CI, 0.68–2.51) compared without AKI. Among AKI patients, Recovered AKI was associated with a 52% lower 1-year mortality compared with maintained AKI. Additionally, maintained AKI was significantly associated with higher 1-year mortality (aOR, 2.67; CI, 2.05–3.47).
Conclusions
Our data suggested that recovered AKI within 48h was a common subtype of AKI following CAG, without increasing mortality. More attention need to be paid to the patients suffering from maintained AKI following CAG.

Abstract
Objective: To report the risk factors, clinical characteristics and treatment courses of pulmonary mucormycosis after lung transplantation(LT). Methods: We included 3 cases with pulmonary mucormycosis after LT from March 2017 to July 2020 in the centre for lung transplantation of China-Japan Friendship Hospital. Twelve cases from Chinese and English literature from China National Knowledge Infrastructure (CNKI), China Biomedical Literature Service System and Pubmed Database from March 1980 to July 2020 were added. The risk factors, clinical characteristics and treatment courses of all cases were summarized and analyzed. Results: Pulmonary mucormycosis occurred in 1.06% (3/284) in our centre. A total of 15 cases with 12 cases from literature included 10 males and 5 females with a mean age of(47±20)years. Thirteen cases occurred after LT, and 2 cases occurred after heart-lung transplantation (HLT). Nine probable cases were diagnosed by positive isolation of the pathogen from bronchoalveolar lavage fluid or sputum. Three proven cases were diagnosed by transbronchial lung biopsy. Meanwhile, the other 3 proven cases diagnosed by CT-guided percutaneous lung biopsy, autopsy and surgical operation respectively. Ten cases (66.7%) were diagnosed with pulmonary mucormycosis within 90 days after lung transplantation. The mortality was as high as 46.67% (7/15), but if it occurred within 90 days, the mortality reached 70% (7/10). The average interval between transplantation and positive isolation of the pathogen was 112.3 (5-378) days. Conclusions: The clinical and radiographic features of pulmonary mucormycosis after LT were nonspecific. It had a high mortality, especially in those occurred within 90 days after LT. The combination of antifungal therapy and surgical resection may contribute to a better outcome of the disease.

Abstract
Objective: To discuss the surgical effect of modified cervical cerclage for the treatment of pregnant women with cervical insufficiency. Methods: The clinical data of 225 pregnant women who underwent modified cervical cerclage in Qilu Hospital (Qingdao) were selected for retrospective analysis from April 2014 to June 2020. Surgical success rate, full-term birth rate, preterm birth rate, prolonged pregnancy weeks and newborn birth weight were compared between singleton and twin pregnancies, preventive cerclage and emergency cerclage, surgery before and after 18 weeks, naturally and in vitro fertilization and embryo transfer (IVF-ET) conceived pregnant women respectively. Results: Among the 225 pregnant women, the gestational weeks of surgery were 14-24+5 weeks, mean gestational weeks of delivery were 38+2 weeks (35+5-39+3 weeks), the number of prolonged gestation were (20.3±5.2) weeks, and the newborn birth weight was (3 065±735) g; the overall surgical success rate was 92.9% (209/225), and the miscarriage rate was 7.1% (16/225); among the surviving newborns, the full-term birth rate was 73.7% (154/209), and the preterm birth rate was 26.3% (55/209). All cases had no intraoperative complications. Among the 225 pregnant women, 202 (89.8%, 202/225) cases were singleton pregnancies, and 23 (10.2%, 23/225) cases were twin pregnancies; 201 (89.3%, 201/225) cases underwent preventive cervical cerclage, and 24 (10.7%, 24/225) cases underwent emergency cervical cerclage; 190 (84.4%, 190/225) cases underwent the surgery before 18 weeks, and 35 (15.6%, 35/225) cases underwent the surgery after 18 weeks; 49 (21.8%, 49/225) cases were conceived by IVF-ET. There was no statistically significant difference in the overall surgical success rate of single and twin group (P>0.05). The full-term birth rate, newborn birth weight and prolonged pregnancy weeks of single group were higher than those of twin group (P<0.05). There were no statistical differences between preventive and emergency cerclage in overall surgical success rate, full-term birth rate, preterm birth rate, and newborn birth weight (all P>0.05). The pregnancy prolonged weeks of preventive cerclage was higher than that of emergency cerclage (P<0.05). There were no statistically significant differences in the overall surgical success rate, full-term birth rate, preterm birth rate and birth weight of newborns at different surgical timings (all P>0.05). The pregnancy prolonged week for those who underwent surgery before 18 weeks was higher than that of surgery after 18 weeks (P<0.05). The premature birth rate of IVF-ET was higher than that of naturally conceived pregnant women (P<0.05). Conclusion: The modified cervical cerclage could effectively prolong the gestational weeks of delivery, reduce the rate of preterm birth, and the operation is simple and easy to promote. It could be used as a surgical option for patients with cervical insufficiency.

Abstract
Occupational noise is one of the most common occupational hazards in the workplace. Long-term exposure to occupational noise could not only lead to the damage of the hearing system, but also may cause a certain impact on the cardiovascular system. Studies have shown that occupational noise exposure was positively associated with cardiovascular diseases, including hypertension, coronary heart disease and myocardial infarction. However, the results of studies on occupational noise exposure and stroke are still controversial. This paper reviews the relationship between occupational noise exposure and hypertension, coronary heart disease, stroke, myocardial infarction by summarizing the epidemiological data of domestic and foreign population in recent years. Our study could provide evidence for the design and implementation of well-designed epidemiological and mechanism studies, and the recognition of the role of occupational noise exposure in the occurrence and development of cardiovascular diseases, so as to better protect workers' health.

Abstract
To evaluate the efficacy of rotation cross-advancement flap method in repairing the nasolabial deformity of complete unilateral cleft lip. A retrospective study was performed to analyze the children who were treated by using the rotating cross-advancement flap for repairing the complete unilateral cleft lip at the Fujian Medical University Union Hospital from October 2018 to July 2019. The clinical data such as patient's lip height, lip length, nostril height, nostril width, nostril area and so on were collected at the pre-operation, post-operation and following-up visits respectively and used to evaluate the efficacy of the treatment. Six children were included in the present study. The ratios of lip height on noncleft side to cleft side were 2∶1 at the pre-operation time. The ratios of nostril height on the noncleft side to the cleft side were about 2∶1. The ratios of the width and the area of the nostril were 1∶2 to 1∶3. At the post-operation time, the ratios of length and height of the lip at the cleft side to the noncleft side were around 1∶1. The shape of the nostrils and nasolabial fold were almost symmetrical between the cleft side and noncleft side. The shapes of the nasal sill were acceptable and the postoperative scars were not obvious. There were no obvious incision healing complications and the treatment effects were satisfactory. Rotation cross-advancement flap method was safe and reliable for repairing the nasolabial deformities in children with complete unilateral cleft lip.

Abstract
Objective: To develop an air particulate protective mask filter test device that can simulate the dynamics process of human breathing. Methods: The new device used two air pumps working alternately to simulate the dynamics process of human breathing. On March 4th to 17th, 2017, the new device and the traditional one-way airflow mask filtration test device were used to measure the internal and external particle levels of 39 masks of 13 models of 6 brands, and then the filtration efficiency of the mask was calculated and the test results were compared. Results: For the mask without breathing valve, there was no statistically significant difference between the filter efficiency test results of the new device and the traditional unidirectional airflow filter performance test device (P>0.05) . For masks with breathing valves, the new device detected that three of them had lower filtration efficiency (99.50% vs 98.63%, P<0.01) . After sealing the mask breathing valve with glue, the filtering efficiency of the mask with a breathing valve detected by the new device significantly improved (98.63% vs 99.50%, P<0.01) . Conclusion: This new device can simulate the dynamic process of human exhalation and inhalation, and measure the filtration efficiency of the mask. For masks with breathing valves, the new device makes it easier to detect the decrease in the filtering efficiency of the mask caused by the breathing valve.

Abstract
Objective: To explore the effects of the application of membrane anatomy concept in sleeve gastrectomy on postoperative nausea and vomiting (PONV) in patients with obesity or metabolic diseases. Methods: A retrospective cohort study was conducted. Clinical data of 88 patients with obesity or metabolic diseases who underwent laparoscopic sleeve gastrectomy in The First Affiliated Hospital of Jinan University from September 2018 to June 2019 were retrospectively analyzed. Forty patients underwent sleeve gastrectomy with membrane anatomy concept as membrane anatomy group, and the other 48 patients underwent traditional sleeve gastrectomy as traditional operation group. There were no significant differences in baseline data between the two groups (all P>0.05). The PONV score of and the times of antiemetic drugs used during 0-6 h and 6-24 h after operation were compared between the two groups. Higher PONV represents more serious nause and vomiting, the score ≥5 is defined as clinical significant PONV. Results: All patients of the two groups successfully completed the operation, and there was no conversion to open, reoperation, and operation-related death. The intraoperative blood loss in the membrane anatomy group was significantly less than that in the traditional surgery group [median: 5.0 (5.0, 5.8) ml vs. 10.0 (5.0, 10.0) ml, Z=-3.265, P=0.001]. There were no significant differences between the two groups in terms of operative time, postoperative hospital stay, gastroesophageal reflux, pain score and postoperative complications (all P>0.05). There was no postoperative bleeding or gastric leakage in either groups. There were no significant differences in PONV score, incidence of clinically significant PONV and use of antiemetics 0-6 h after operation between two groups (all P>0.05). From 6 to 24 hours after operation, compared with traditional surgery group, the membrane anatomy group had lower PONV score (4.6±0.9 vs. 5.1±0.7, t=-2.192, P=0.007), lower incidence of clinically significant PONV [55.0% (22/40) vs. 83.3% (40/48), χ(2)=8.414, P=0.004] and less use of antiemetics [3 times: 10.0% (4/40) vs. 27.1% (13/48), Z=-2.880, P=0.004]. Postoperative follow-up ranged from 1 to 6 months (median 3), 32 cases in membranous anatomy group and 38 cases in the traditional operation group were followed up. One case in the traditional operation group received symptomatic treatment in the local hospital due to functional intestinal obstruction 1 month after surgery and was discharged after recovery. The remaining patients had no postoperative complications and were not readmitted to hospital. Conclusion: Sleeve gastrectomy based on membrane anatomy in the treatment of patients with obesity or metabolic syndrome can make surgical procedure more precise and meticulous, reduce the intraoperative bleeding and the incidence of PONV.

Abstract
Objective: To investigate the relationship between urinary polycyclic aromatic hydrocarbons(PAHs) metabolites and pulmonary function in community population. Methods: A total of 4 812 participants were recruited from two communities in Wuhan city from April to May 2011 and two communities in Zhuhai city in May 2012. Information of demographic characteristics and life style was collected by semi-structural questionnaire. Physical examination was performed and pulmonary function was measured. Morning urine was also collected. The concentration of 12 urinary PAHs metabolites was tested and classified into four types by chemical structure, including hydroxynaphthalene, hydroxyfluorene, hydroxyphenanthrene and hydroxypyrene. The level of pulmonary function in different group of urinary PAHs metabolites was compared by using covariance analysis. The association of the urinary PAHs metabolites and pulmonary function was analyzed by using generalized linear model, and the interaction of different population characteristics and life style on the association was analyzed. Results: The age of participants was(51.99±13.64) years old, and 67.66% (n=2 565) of the population were women. The M (P(25), P(75)) of concentration of total urinary PAHs metabolites was 5.72 (3.91,8.72) μg/mmol Cr. After controlling for variables including age, gender, city, Waist-to-Hip Ratio, smoking status, drinking situation, physical activity, cooking meals at home or not, kitchen ventilation and exposure to dust as confounding factors, generalized linear model showed that each 1-unit increase in log-transformed levels of hydroxynaphthalene, hydroxyfluorene, hydroxyphenanthrene, hydroxypyrene and total PAHs was associated with 26.83 (95%CI: -48.18, -5.48) , 21.86 (95%CI: -40.49, -3.23), 26.18(95%CI: -48.27, -4.09), 34.95 (95%CI: -55.95, -13.94), and 35.23 (95%CI: -58.93, -11.54) ml reduction of FVC and 29.36 (95%CI: -47.23, -11.48), 20.79 (95%CI: -36.39, -5.19), 22.65 (95%CI: -41.15, -4.15), 31.44(95%CI: -49.03, -13.85), and 33.20 (95%CI: -53.04, -13.36) ml reduction of FEV(1) respectively (all P values<0.05). Compared to non-alcohol users and participants with home cooking, the association was more evident in alcohol users and participants without home cooking(P for interaction<0.05). Conclusion: The exposure to PAHs was associated with decreased pulmonary function, and the association was more evident in alcohol users and participants without home cooking.

Abstract
Objective: To investigate the incidence of venous thromboembolism (VTE) in lung transplant (LT) recipients. Methods: The clinical data on 124 consecutive patients who underwent lung transplant at Lung Transplantation Center of China-Japan Friendship Hospital from March 2017 to September 2018 were retrospectively collected. Deep venous thrombosis (DVT) was ascertained by vascular ultrasound. Pulmonary embolism (PE) was diagnosed by either chest computed tomography pulmonary angiogram or ventilation/perfusion scan. The risk factors in those patients with postoperative VTE were studied. Results: A total of 124 lung transplant recipients including 78 single lung transplant recipients (62.9%) and 46 bilateral lung transplant recipients(37.1%) were enrolled. Preoperative and postoperative prophylactic anticoagulant was used in 52 patients(52/124, 41.9%) and 69 patients(69/124, 55.6%) respectively. Thirty-two patients developed postoperative VTE among 124 consecutive patients. The overall incidence rate of VTE among 124 LT recipients was 25.8%. The median time to VTE episode following lung transplant was 22.5 days (range 4-295 days). The percentage of DVT in VTE was 93.8%(30/32), involving 1-8 (2.83±1.86) veins. And 60.0% of DVT was from lower extremities and 56.7% located in upper extremities (P>0.05). Four patients (4/32,12.5%) had PE episodes, and half of them suffered from only PE without DVT. The use of extracorporeal membrane oxygenation (ECMO) in 32 patients with VTE was 90.6% (29/32), which was significantly higher than that without VTE (64/92,69.6%, P=0.033). However, there was no difference in the use of peripherally inserted central catheter (PICC) between two groups (96.9% vs 81.5%, P=0.067). Resolution of VTE was successfully accomplished by anticoagulant therapy with long-term use of low molecular weight heparin in 30 patients (93.7%) and followed by oral warfarin in 2 patients (6.3%). Three months follow-up data after anticoagulant therapy showed that total and partial vascular recanalization rate was 65.6%(21/32) and 34.4%(11/32), respectively. Despite anticoagulation-related bleeding complications in three patients, no serious consequences occurred. Conclusions: VTE was frequent in LT recipients. It was speculated that ECMO utilization may be a major risk factor for high incidence of VTE in LT recipients. Aggressive VTE screening/treatment protocols were suggested to be implemented in LT recipients.

Abstract
Objective: Investigate the causes of poor prognosis of mechanical thrombectomy in the time window of acute ischemic stroke (AIS) with anterior circulation. Methods: A retrospective analysis was made on the data of 78 patients with anterior circulation AIS who underwent mechanical thrombectomy in the time window from January 2017 to December 2017 in the Department of Vascular Neurosurgery of Liaocheng Brain Hospital. The modified Rankin scale (mRS) was used to evaluate the prognosis of the patients 3 months after operation. According to the prognosis,the patients were divided into the group with good prognosis (42 cases, mRS<2 points) and the group with poor prognosis (36 cases, mRS<3 points). Univariate and multivariate Logistic regression analysis was used to analyze the related factors of poor prognosis. Results: (1) Univariate analysis showed that the prognosis of patients with good combination and primary stenosis of diabetes mellitus and atherosclerosis was lower than that of patients with poor prognosis (P<0.05). The collateral circulation compensation rate and vascular recanalization rate of patients with good prognosis were higher than those of patients with poor prognosis (P<0.05). Learning significance (P<0.05). (2) Multivariate analysis showed that diabetes mellitus (P=0.035), collateral circulation compensation (P=0.011) and primary atherosclerotic stenosis (P=0.042) were independent risk factors for poor prognosis. Conclusion: Perfect preoperative evaluation and strict screening of patients, good collateral circulation compensation,individualized treatment for patients with primary atherosclerotic stenosis,and strict control of postoperative hyperglycemia can improve the clinical prognosis of endovascular therapy.

Abstract
Emulsified polycolloid substrate (EPS) was developed and applied in situ to form a biobarrier for the containment and enhanced bioremediation of a petroleum-hydrocarbon plume. EPS had a negative zeta potential (-35.7 mv), which promoted its even distribution after injection. Batch and column experiments were performed to evaluate the effectiveness of EPS on toluene containment and biodegradation. The EPS-to-water partition coefficient for toluene (target compound) was 943. Thus, toluene had a significant sorption affinity to EPS, which caused reduced toluene concentration in water phase in the EPS/water system. Groundwater containing toluene (18 mg/L) was pumped into the three-column system at a flow rate of 0.28 mL/min, while EPS was injected into the second column to form a biobarrier. A significant reduction of toluene concentration to 0.1 mg/L was observed immediately after EPS injection. This indicates that EPS could effectively contain toluene plume and prevent its further migration to farther downgradient zone. Approximately 99% of toluene was removed after 296 PVs of operation via sorption, natural attenuation, and EPS-enhanced biodegradation. Increase in total organic carbon and bacteria were also observed after EPS supplement. Supplement of EPS resulted in a growth of petroleum-hydrocarbon degrading bacteria, which enhanced the toluene biodegradation.

Abstract
Objective: s To investigate the distributions of single nucleotide polymorphisms (SNPs) of tissue factor (TF) and its inhibitor tissue factor pathway inhibitor (TFPI) and analyze the association of the SNPs with venous thromboembolism (VTE) in lung cancer patients. Methods: Between October 2009 and August 2013, a total of 152 hospitalized patients with newly diagnosed primary non-small cell lung cancer were enrolled from Beijing Chao Yang Hospital. Among them [male 105 cases, female 47 cases, with an age of (62.4±13.2) years old], 40 cases were lung cancer patients with VTE, 112 cases were lung cancer patients without VTE. In the same period, 79 healthy controls were included from the physical examination center. All patients' blood specimens were collected and their DNA was isolated. The selected SNPs were TF+ 5466A/G, TFPI-287T/C and TFPI-33T/C and they were investigated by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) followed by validation of DNA sequence analysis. Results: Allelic frequencies of TF+ 5466G, TFPI-287C and TFPI-33C were 2.5%, 33.8% and 8.8%, respectively. There was no significant difference among the three groups in genotype or allele frequency distributions of TF+ 5466A/G, TFPI-287T/C and TFPI-33T/C polymorphisms (all P>0.05). There was no difference from different genders and ages in allele or genotype frequency distributions of TF+ 5466A/G, TFPI-287T/C and TFPI-33T/C polymorphisms among the three groups (all P>0.05). Meanwhile, the frequency distributions of genotype and allele of the three SNPs were not associated with lung cancer patients with VTE (all P>0.05). Still, no relationship was found between genotype or allele frequency distributions of the three SNPs with prognosis of lung cancer patients with VTE. Conclusion: Genotype alterations in TF+ 5466A/G, TFPI-287T/C and TFPI-33T/C may be unrelated to the occurrence of VTE and the prognosis of lung cancer patients with VTE.

Abstract
AIMS The aim of the study was to survey rhizobial biogeography and to inoculate soybean with selected rhizobia in China to enhance symbiotic nitrogen fixation (SNF). METHODS AND RESULTS Biogeography, genetic diversity and phylogeny of soybean rhizobia were surveyed. Inocula were prepared and applied to soybean. Results showed that Bradyrhizobium elkanii and Ensifer fredii were widely distributed in acid and alkaline soils respectively. Available iron was detected as the first determinant for distribution of the two rhizobia and the soybean varieties did not greatly affect the rhizobial compatibility. Geographical latitude and precipitation in June were the main geographical and climatic factors affecting the rhizobial distribution. Inoculation with selected rhizobia increased the nodule number, fresh weight, occupation ratio, seed protein content and soybean yields. CONCLUSIONS Selection and application of effective soybean rhizobia across China according to biogeography were clarified to promote the SNF, thereby improving soybean yield. SIGNIFICANCE AND IMPACT OF THE STUDY Rhizobial diversity and biogeography were evaluated systematically in six sites across China. Available iron and soil pH are found to be the most important determinants for the distribution of soybean rhizobia. Inoculation to soybean enhances SNF, positively correlating to the increase in soybean yield and seed protein content.

Abstract
Nowadays, particulate air pollution has been a global environmental problem. Numerous studies has shown that long-term exposure to high level of airborne particulate matter (PM) can damage human health. Respiratory system, as a direct portal to contact with particulate matter, can be more susceptible to airborne particulates. Summarizing latest five-year epidemiological research, the present review is focused on the effects of PM on respiratory system health in different age groups. In detail, we investigated the harmful effect of PM, or its components on three common respiratory diseases, including lung function decline, chronic obstructive pulmonary disease (COPD) and asthma. The result showed that, to a certain degree, PM could induce the decline of lung function, the development and the exacerbation of COPD and asthma by oxidative stress and inflammatory reaction. And it may prompt that exposure to PM can be an improtant risk factor for the respiratory system health.

Abstract
OBJECTIVE To explore the association between DNA damage-related genetic variants and lung cancer susceptibility in a Han Chinese population. METHODS This case-control study enrolled patients from the Cancer Hospital of Jiangsu Province and Jiangsu Province Hospital from 2003 to 2009. Controls were randomly selected from individuals who visited the same hospital or a community-based health examination program during the same time period. A 5 ml venous blood sample was obtained from each participant and epidemiological information was collected on a standard questionnaire. Illumina Infinium(®) BeadChip was used for genotyping of 35 DNA damage-related single nucleotide variations (SNVs), which were identified in our previous study. Multivariate and binary logistic regressions were used to calculate the OR and 95%CI for lung cancer risk. HaploReg V4.1 and Regulome DB were used to understand functional annotation on important SNV. RESULTS The distributions of age (61.06±10.15) vs. (61.32±11.07) years; t=-0.72, P=0.473) and sex (χ(2)=1.81, P=0.179) were similar between cases and controls. However, the case group had a higher frequency of smokers (61.08% vs. 48.54%; χ(2)=50.04, P<0.001) and heavy smokers (42.28% vs. 24.07%; χ(2)=122.32, P<0.001). Among the 34 SNVs that passed quality control, two SNVs were significantly associated with lung cancer risk after adjustments for age, sex and cumulative smoking dose: rs9267576 C>A (CA genotype/CC genotype, OR=1.56, 95% CI: 1.01-2.40) and rs3130683 A>G (AG genotype/AA genotype, OR=1.87, 95%CI: 1.13-3.09). After step-wise logistic regression analysis, only the rs3130683 SNV was retained in the model, indicating that the association between rs9267576 and lung cancer may be due to the effect of rs3130683. Functional annotation indicated that rs3130683 was located in the promoter and enhancer regions, and was an expression quantitative trait loci of HLA. The Cancer Genome Atlas indicated that expression of HLA-C, DQB1, DRB1 and DRB5 in lung cancer tissue was significantly lower than in paired normal tumor-adjacent tissue, with down-regulation of the four respective genes in 81.3%, 88.8%, 90.7% and 90.7% of lung cancer tissues (P-values were 6.68×10(-15), 2.21×10(-13), 2.20×10(-16), 2.58×10(-13), respectively). CONCLUSIONS The SNV rs3130683 (A>G) was associated with the risk of lung cancer in a Han Chinese population. This SNV may affect the risk of lung cancer by regulating HLA expression.

Abstract
Objective: To investigate the modulation role of Gas6 in silica-induced inflammatory effect on human macrophages. Methods: Differentiated THP-1 macrophages were exposed to different concentrations of silica for 6 h and 24 h. Additionally, silica-activated macrophages were treated with different concentrations of recombine human Gas6 and Gas6 antibody respectively. Cell viabilities were determined by CCK-8 kit. Expression levels of Gas6 and inflammatory cytokines (TNF-α, IL-1β and IL-6) were measured by ELISA assay kits. Results: Silica particles induced clear dose-dependent decreases of cell viability and Gas6 expression at both 6 h and 24 h. The cell viability of 24 h is lower than 6 h at the same concentration of silica (P<0.05). Furthermore, silica activated macrophages treated with Gas6 antibody induced significant decreases of Gas6 both at 6 h and 24 h (P<0.05). After pretreated with various concentrations of Gas6 antibody, silica induced higher expressions of inflammatory cytokines (TNF-α, IL-1β, IL-6) in dose-dependent manners at two time points. Addition of exoge-nous Gas6 significantly suppressed silica-induced inflammatory cytokines concentrations mentioned above in the cell culture supernatants in clear dose-dependent manners. Conclusion: Exogenous Gas6 could inhibit the secre-tion of inflammatory cytokines in macrophages, while the block of Gas6 might enhance this inflammation.

Abstract
Objective: To investigate the potential dose-response relationship between PCDD/Fs inhalational exposure and oxidative damage to DNA and lipid in foundry workers. Methods: The participants were divided into three groups, including exposure group, administrator group and control group. The concentrations of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in air environment were determined by isotope dilution high resolution capillary column gas chromatography/high resolution mass spectrometry (HRGC-HRMS). The inhalational dose of PCDD/Fs were evaluated by Houmen's model. Urinary 8-OHdG was analyzed by high performance liquid chromatography-electrochemical detector (HPLC-ECD). Urinary 8-iso-PGF2ɑ were determined by ELISA. Results: The PCDD/Fs environmental concentrations of three groups (pg·TEQ/m) were 0.21±0.08, 0.03±0.01, 0.0012±0.0007 (P<0.05) , respectively. The inhalational dose of exposure group (92.54 (32.90~264.49) fg·TEQ/kg·d) was 5.4 folds higher than the administrator group, and was 201 times more than control group. The levels of urinary 8-OHdG (nmol/L crea) of three groups were 3.25 (1.07~15.36) , 2.72 (0.75~16.07) , 2.17 (0.38~17.07) (P<0.05) and the levels of urinary 8-iso-PGF2ɑ (nmol/L crea) were 19.11 (9.33~76.50) , 20.95 (8.40~79.31) , 11.48 (4.85~37.80) (P<0.05) , respectively. The multiple linear regression analysis revealed that there were significantly increased trend for levels of urinary 8-OHdG and 8-iso-PGF2ɑ as PCDD/Fs exposure levels increased, after adjustment for age, sex, smoking statue, alcohol use and BMI (P<0.01). Conclusion: There was a dose-response relationship between PCDD/Fs inhalational exposure and oxidative damage in foundry workers.

Abstract
OBJECTIVE To evaluate the clinical, radiological and pathological features of primary or metastatic malignancies presenting with multiple lung cavities. METHODS A total of 38 cases met the inclusion criteria and had adequate imaging data for retrospective review between June 2006 and August 2013. There were 30 cases of primary lung cancer, and 8 cases of pulmonary metastasis including 6 gastrointestinal tract malignancies, 1 vulva malignancy and 1 scalp malignancy. There were 21 females and 17 males, with a median age of 63 years. RESULTS Cough and expectoration were the most common clinical manifestations of primary lung cancer(22/30). There were 4 main types of lung cavities, including thick-walled cavities(n=12), circular cavities (n=24), thin-walled cavities or cystic cavities (n=11), cavities or multi-cystic changes within airspace consolidation or ground glass opacity(n=11). The cavitary lesions were often accompanied by pulmonary nodules, mass and ground glass opacity(32/38, 84%). The presence of internal soft-tissue septa in the cavity was commonly seen(17/38, 45%). The 4(th) type of cavity and presence of air-fluid levels were only found in lung adenocarcinoma, including 5 cases of mucinous adenocarcinoma. In both primary lung cancers and metastatic tumors, adenocarcinoma was the most common histological type (29/30 and 6/8, respectively). The other histological types included 1 case of lung squamous cell carcinoma, 1 vulva adenosquamous carcinoma and 1 scalp angiosarcoma. The possible mechanisms of cavity formation included necrosis, mucin-secretion air-containing cystic spaces in papillary tumors and the check-valve mechanism. CONCLUSIONS Adenocarcinoma was the most common histological type in multiple cavitary primary lung cancers and metastatic tumors. These cavities showed varied radiological features and were easy to be misdiagnosed as benign cavitary lung diseases.

Abstract
OBJECTIVE To investigate the potential association between 23 urinary metals and mean platelet volume (MPV) among a community population in Wuhan. METHODS A total of 3 053 community residents who lived in the sampling buildings for more than 5 years, aged from 18 to 80 years, were recruited using a stratified, cluster sampling approach in Wuhan city, China. Blood and urine samples were obtained from participants in the morning under fasting conditions. Urinary metals, including aluminum, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, arsenic, selenium, rubidium, strontium, molybdenum, cadmium, tin, antimony, barium, tungsten, thallium, lead and uranium, were measured by inductively coupled plasma mass spectrometry. The MPV contents were determined using a fully automated clinical chemistry analyzer. Participants with missing data on covariates or cardiovascular disease were excluded. According to the reference intorvals of MPV for Chinese adults, the participants were classified into normal (7.0-11.0 fl) and high MPV (>11.0 fl) subgroups. Data from 2 203 participants were used to evaluate the associations between urinary metals and MPV levels using generalized linear regression models, and the risk of abnormal elevation of MPV using multivariable logistic regression models. The false discovery rate (FDR)-corrected P-value from 23 hypothesis tests was used to adjust for multiple testing. RESULTS After adjusting for potential confounders, urinary concentrations of arsenic (P50=2.431 μg/mmol creatinine) and molybdenum (P50=4.035 μg/mmol creatinine) were significantly associated with increased MPV levels and the risk of abnormal elevation of MPV. In contrast, urinary aluminum (P50=2.706 μg/mmol creatinine) and thallium (P50=0.046 μg/mmol creatinine) were associated with decreased MPV levels, but also the risk of abnormal elevation of MPV. The regression coefficients and 95% CIs were 0.119 (0.043-0.196) for arsenic (FDR-adjusted P=0.018), 0.119 (0.042-0.195) for molybdenum (FDR-adjusted P=0.018), -0.115 (-0.195--0.034) for aluminum (FDR-adjusted P=0.029), and -0.307 (-0.386- -0.228) for thallium (FDR-adjusted P<0.001), respectively. When comparing the extreme quartiles for arsenic, molybdenum, aluminum and thallium, adjusted OR and the 95%CIs were 1.830 (1.382-2.423), 1.496 (1.125-1.989), 0.566 (0.412-0.779) and 0.302 (0.219-0.416), respectively, and FDR-adjusted P-values were <0.001,<0.014,<0.008 and<0.001, respectively. Moreover, significant associations were found between an increased risk of abnormal MPV elevation with urinary iron (P50=6.716 μg/mmol creatinine) , antimony (P50=0.014 μg/mmol creatinine) and uranium (P50=0.003 μg/mmol creatinine) , and a decreased risk with urinary tungsten (P50=0.010 μg/mmol creatinine) and lead (P50=0.265 μg/mmol creatinine) . When comparing the extreme quartiles for iron, antimony and uranium, the respective adjusted OR (95%CI) were 1.866 (1.395-2.496), 1.507 (1.111-2.043) and 1.452 (1.063-1.984), and the respective FDR-adjusted P-values were <0.001,<0.022 and<0.012. The respective adjusted OR (95%CI) were 0.551 (0.417-0.726) and 0.534 (0.394-0.725), and the respective FDR-adjusted P-values were<0.001 and<0.001, when comparing the extreme quartiles for tungsten and lead. Based on multi-metal models, urinary chromium (P50=0.120 μg/mmol creatinine) and selenium (P50=0.646 μg/mmol creatinine) were associated with increased risk of abnormal MPV, while urinary nickel (P50=0.193 μg/mmol creatinine) was associated with decreased risk of abnormal MPV. When comparing the extreme quartiles for chromium, selenium and nickel, adjusted OR (95% CI) were 1.578 (1.054-2.363), 1.718 (1.159-2.549) and 0.535 (0.373-0.767), respectively, and the FDR-adjusted P-values were 0.017, 0.028 and 0.002, respectively. CONCLUSION In the general population of Wuhan city, exposure to aluminum, chromium, iron, nickel, arsenic, selenium, molybdenum, antimony, tungsten, thallium, lead and uranium were all associated with abnormal MPV elevation.

Abstract
OBJECTIVE To investigate the association between levels of 23 urinary metals and lung function, and explore their does-response relationships in the general population of Wuhan province, China. METHODS This was a cross-sectional study that enrolled volunteers from two communities of Wuhan between April and May 2011. All volunteers had resided in Wuhan for at least 5 years. Information from questionnaires and physical examinations were collected and lung function was assessed. Data from 2 540 volunteers were included. Urinary levels of 23 metals were measured by inductively coupled plasma mass spectrometry (ICP-MS). The relationship between urinary metals and lung function was analyzed with single and multiple regression models. RESULTS The mean age of the study population was 52.8 years. Mean levels of urinary metals, after adjustment for creatinine, including cobalt, copper, zinc, nickel, antimony and barium were 0.02, 0.68, 23.80, 0.20, 0.10, 0.34 and 0.26 μg/g creatinine, respectively. There were significant concentration-response relationships between increases in some urinary metals and reduced lung function. Single-metal regression models demonstrated that for each 1-unit increase in urinary levels of cobalt, lncopper, lnzinc, lnantimony, there was a reduction in forced vital capacity (FVC) of 0.091 L (95%CI: -0.155--0.027), 0.101 L (95%CI: -0.178--0.025), 0.094 L (95%CI: -0.172--0.027) and 0.118 L (95% CI: -0.203--0.033), respectively. Each 1-unit-increase in urinary lncobalt, lnnickel, lnstrontium, lnantimony, lnthallium, lnlead was associated with a reductions in forced expiratory volume in 1 sec (FEV1) of 0.070 L (95%CI: -0.124--0.016), 0.063 L (95%CI: -0.118--0.007), 0.063 L (95%CI: -0.124--0.002), 0.092 L (95%CI: -0.164--0.020), 0.055 L (95%CI: -0.105--0.005), 0.081 L (95%CI: -0.148--0.014), and 0.097 L (95% CI: -0.151--0.042), respectively. With respect to metal co-exposure, FVC was significantly associated with elevated urinary levels of cobalt, Cu and Sb, with reductions of 0.126 L (95%CI: 0.037-0.216) and 0.106 L (95% CI: 0.021-0.192), respectively, while FEV1 was significantly associated with elevated urinary Co, Sb, Ba and Pb, with reductions of 0.067 L (95% CI: -0.129--0.005), 0.142 L (95% CI: -0.247--0.037), 0.073 L (95% CI: -0.142--0.003) and 0.104 L (95% CI: -0.175--0.034), respectively. CONCLUSIONS Certain urinary metals were potentially associated, in a dose-dependent manner, with reduced lung function in the general population. Co-exposure to metals had stimulative and anti-stimulative effects on lung function.

Abstract
OBJECTIVE To investigate the associations between 21 metals in fine particulate matter (PM2.5) and their corresponding concentrations in urine in the general population. METHODS Between April and May 2011, this panel study enrolled 120 residents using random sampling approach in Wuhan communities which contained 3 035 subjects. Participants were aged 18 to 80 years and had lived in the sampling buildings for at least 5 years. Data from basic questionnaires, physical examinations, and morning blood and urine samples under fasting conditions were collected. Participants with missing data were excluded. Finally, 83 particpants included. Participants were instructed to use personal air samplers to continuously monitor PM2.5 for 24 h. The following 21 metals were measured in PM2.5 and urine by inductively coupled plasma mass spectrometry: aluminum, titanium, vanadium, chromium, manganese, cobalt, nickel, copper, zinc, arsenic, selenium, rubidium, strontium, molybdenum, cadmium, tin, antimony, barium, tungsten, thallium and lead. The associations between PM2.5 metals and urinary metals were investigated using generalized linear regression models. RESULTS The age of the study population was (51.5±6.3)years. After adjusting for age, sex, smoking status, BMI, education and income, elevated urinary chromium was significantly associated with increased chromium concentrations in personal PM2.5. The least square means (standard deviation) of urinary chromium in participants classified as having low exposure (<12.491 ng/m(3)), intermediate exposure (12.491-32.388 ng/m(3)) and high exposure (>32.388 ng/m(3)) were (-1.334±0.756), (-1.114±0.813) and (-0.718±0.645) μg/mmol creatinine, respectively (P=0.009). However, the association between urinary and personal PM chromium was not observed after additionally adjusting for false discovery rate (P>0.05). Furthermore, the results demonstrated that other metals in PM2.5 were not related to their corresponding concentrations in urine of subjects. CONCLUSION Urinary concentrations of metals did not reflect human exposure to metals in air, and may not be appropriate as an index to assess personal exposure to metals in particulate matter.

Abstract
Although anticardiolipin antibody (aCL) has been suggested to be a potent risk factor for thrombosis and atherosclerosis in multiple arterial beds, conflicting results exist between aCL and cerebral ischemia in the general stroke population. To elucidate if this discrepancy relates to the heterogeneity of underlying etiologies, the blood beta2-glycoprotein I dependent-aCL in 432 Taiwanese adults was examined. The associated cerebral ischemia in these patients was classified into five subtypes according to the cause of cerebral ischemia. The results were compared with those in 100 healthy controls. A definite increase of aCL-IgG isotype was found in 41 patients (9.35%) and four controls (4.0%). The relative risk was 2.52. The frequency of increased aCL-IgG was 12.2%, 12.8%, 8.8%, 3.9%, and 3.5% in patients with large-artery atherosclerotic disease, stroke of unknown etiology, small-artery occlusive disease, cardioembolism, and stroke of other known etiology, respectively. Only patients with large-artery atherosclerotic disease (p<0.025) and stroke of unknown etiology (p<0.05) had higher frequencies of increased aCL than those in control subjects. The frequencies of abnormal results of activated partial thromboplastin time, antinuclear factor, Coombs’ test, and venereal disease research laboratory were 2.84%, 1.22%, 1.02%, and 1.34% in these 41 patients, respectively. Accordingly, aCL-IgG selectively increases in patients with large-artery atherosclerosis and stroke of unknown etiology, reflecting selective activation of humoral immunity for aCL in the pathogenesis of cerebral ischemia.

Abstract
Abnormal increases of antiphospholipid antibody and plasma homocysteine levels are recently emerging as nonlipidic risk factors for cerebral atherogenesis and thrombosis. Both antiphospholipid antibody and homocysteine share many similar bioeffects in hemostasis, but their interaction is still inconsistent. In this study, we examined the relation between the plasma homocysteine level and lupus anticoagulant, anticardiolipin antibody, and anti-β2-glycoprotein I antibody in patients with noncardiac cerebral ischemia. Systemic lupus erythrematosus patients were excluded. The results showed a higher frequency of moderate hyperhomocysteinemia in patients with an abnormal increase of lupus anticoagulant only. Neither the serum folate and cobalamin levels nor methylenetetrahydrofolate reductase allele mutation contributes to this result. Accordingly, homocysteine interacts with lupus anticoagulant to promote cerebral atherosclerosis and ischemia. The role of vasculopathic or prothrombotic autoantibody generation in response to specific pathological change such as hyperhomocysteinemia warrants further investigation.
