Abstract
INTRODUCTION Caustic substance ingestion is frequently life-threatening, and its pathological mechanisms of tissue damage are well documented. However, few studies have assessed the combined effects of pH and the ingested dose on patient outcomes. Additionally, the miscellaneous chemical properties are not immediately available for providing predictive insights to physicians. This study aimed to provide a new perspective of the risk assessment of caustic substance ingestion based on the pH and dose. METHODS The retrospective study analyzed adults treated for caustic substance ingestion at Chang Gung Memorial Hospital between January 1999 and December 2018. Uniformly strict inclusion/exclusion criteria and a double-checked process during chart review were adopted. All patients underwent urgent esophagogastroduodenoscopy (EGD) within 24 h. Caustic mucosal damage was graded using Zargar's modified endoscopic classification. The pH and ingested dose of caustic substances were clearly recorded. Statistical analyses were conducted using IBM SPSS, version 22. RESULTS Based on the 468 enrolled cases, the pH and dose were valuable predictors of the extent of gastrointestinal tract injury, commonly encountered complications, and long-term overall survival outcomes. Risks of mortality and perforation were dose-dependent for acids and pH-dependent for alkalis. The severe EGD findings (grade ≥ 2b) in this study were pH-dependent for both substances and additionally dose-dependent for acids. CONCLUSION Combining pH and dose, we proposed a new perspective for the risk assessment of caustic substance ingestion. Such findings may provide predictive insights for resolving clinical uncertainty before the availability of examination results. "Large doses of acids" and "high pH of alkalis" deserve special attention. This new perspective with a retrospective nature requires further validation.

Abstract
Purpose High prevalence of psychiatric comorbidities (PCs) has been widely documented in caustic substance ingestion cases. However, their effect on the clinical features and prognostic outcomes remains unclear due to the paucity of discussion. We report on detailed clinical courses with long-term multifaceted outcomes and review the association between caustic ingestion and each specific PC. Patients and Methods The retrospective chart review included 396 adults (median follow-up, 16.6 months) with and 377 without (control group) PCs treated between 1999 and 2018 at Chang Gung Memorial Hospital. All PCs were diagnosed/confirmed by psychiatrists through face-to-face interviews. Results The PCs predicted serious esophagogastroduodenoscopy grading, higher rates of admission/surgery/intensive care unit stay, increments of systemic/gastrointestinal complications, and poorer 5-year overall survival rates. The poor survival among patients with PCs was highly consistent with their baseline characteristics. Significantly advanced age, more non-PCs, alcoholism, illicit drug abuse, and baseline unhealthy status resulted in statistically higher risks of severe complications and limited recovery. Conclusion PCs changed clinical patterns and had critical roles in the survival outcomes of caustic injury victims. Clinical awareness achieves benefit by limiting injuries in mild cases or allowing emergent interventions in severe cases. Future studies based on worldwide populations are essential for realizing geographic differences.

Abstract
Objective: To investigate the efficacy and safety of daratumumab in relapsed and refractory multiple myeloma (RRMM). Methods: The efficacy and adverse events (AEs) of daratumumab based regimens were retrospectively analyzed in 37 patients with RRMM from Peking University People's Hospital, Beijing Hospital and Fu Xing Hospital affiliated to Capital Medical University in China. The deadline for inclusion was December, 2019. Results: Among the 37 patients, 35 patients were available for response evaluation. The overall response rate (ORR) was 68.6%, which was better in patients receiving 16 mg/kg daratumumab than in those with fixed doses of 800 mg daratumumab [ORR: 78.3%(18/23) vs. 40.0%(4/10)]. The percentage of infusion related reactions of daratumumab was 27.0%(10/37). The most common hematological AEs were lymphocytopenia and thrombocytopenia, with the incidences of grade 3 or more severe 59.5%(22/37) and 43.2%(16/37) respectively. Pulmonary infections(37.8%, 14/37) were the most common non-hematological AEs. One patient with positive hepatitis B surface antigen (HBsAg) and two patients dependent on dialysis were safely treated with daratumumab. Conclusion: Daratumumab is highly effective in relapsed and refractory multiple myeloma. Adverse reactions are mild and well tolerable.

Abstract
UNLABELLED Alendronate is effective in preventing second hip fracture in osteoporotic patients. However, no consensus exists on the duration that is effective in preventing a second hip fracture. Our study demonstrated that risk can be reduced when the prescription is ≥ 6 months for the year following the index hip fracture. INTRODUCTION Alendronate is effective in preventing second hip fracture in osteoporotic patients. However, no consensus exists on the accurate medication possession ratio (MPR) that is effective in preventing a second hip fracture. Our objective was to compare the risk of second hip fracture in patients treated with different MPR of alendronate. METHODS In this population-based cohort study, data from National Health Insurance Research Database of Taiwan were analyzed. Patients 50 years and older who had an index hip fracture and were not receiving any osteoporotic medications before their fracture during 2000-2010 were included. The cohort consisted of 88,320 patients who were new alendronate users (n = 9278) and non-users (n = 79,042). Those without alendronate were matched 4:1 as the control group. Patients were subdivided into those with no medication, MPR < 25%, MPR 25-50%, MPR 50-75%, and MPR 75-100%. Cox proportional hazard models were used to calculate the adjusted hazard ratios for different MPRs of alendronate. RESULTS After matching, 38,675 patients were included in this study; 20,363 (52.7%) were women, and 30,940 (80%) patients were without medication of alendronate. During follow-up on December 31, 2012, 2392 patients had a second hip fracture, for an incidence of 1449/100,000 person-years. Patients with alendronate MPR 50-75% had a lower risk of a second hip fracture compared to non-users (hazard ratio 0.66). When the MPR increased to 75-100%, the hazard ratio decreased to 0.61. CONCLUSIONS In this population-based cohort study, risk of a second hip fracture can be reduced when the alendronate MPR is ≥ 50% for the year following the index hip fracture. As the MPR increases, the risk of a second hip fracture decreases.

Abstract
Triglycerides (TG) not only provide energy for infants but have important physiological functions. Understanding the composition and structure of TG in human milk is conducive to the development of infant formulas. In this study, TG species in human milk from 3 provincial capitals (Zhengzhou, Wuhan, and Harbin) in different regions of China were determined through C18 HPLC electrospray ionization tandem mass spectrometry (MS). The results showed that in human milk from these 3 regions, oleoyl-palmitoyl-linoleoylglycerol (OPL; 16.55, 19.20, and 18.67%, respectively) was more abundant than oleoyl-palmitoyl-oleoylglycerol (OPO; 10.08, 10.22, and 12.03%, respectively). Subsequently, regioisomeric and enantiomeric analysis of main TG in the human milk were performed on silver ion and chiral HPLC atmospheric pressure chemical ionization mass spectrometry (APCI)-MS, respectively. The results showed that rac-OPL (above 85%), rac-OPO (above 85%), rac-palmitoyl-oleoyl-oleoylglycerol (PPO; above 90%), and rac-OLaO (above 70%) were the main regioisomers of OPL, OPO, PPO, and lauroyl-oleoyl-oleoylglycerol (LaOO), respectively. The relative ratios of enantiomer pairs of rac-OPL (rac-OPL1 and rac-OPL2) were about 37 and 63%, respectively.

Abstract
OBJECTIVE Inflammatory diseases are risk factors for osteoporosis. We aimed to explore whether fibrinogen, which is linked to chronic inflammation, is associated with bone mineral density (BMD) in menopausal women. METHODS In this cross-sectional study, we analyzed 339 menopausal women from Zhejiang Province between January 2016 and October 2019. Linear regression analysis was performed to assess the relationship between fibrinogen and BMD. RESULTS Significant inverse association was observed between the serum fibrinogen level and BMD in menopausal women. The mean BMD in each quartile of fibrinogen level was 0.901, 0.897, 0.892, and 0.855 g/cm2, respectively (p = 0.027). After adjusting for age, body mass index, metabolic profiles, blood inflammatory factors, and serum levels of estradiol, calcium, phosphorus, and alkaline phosphatase, fibrinogen levels remained significantly associated with BMD (regression coefficients for quartiles 1-3 vs. quartile 4 were 0.046, 0.027, and 0.036, respectively; p for trend <0.05). CONCLUSIONS Higher fibrinogen levels were associated with lower BMD in menopausal women, which was independent of age, body mass index, estradiol, and other factors. Therefore, serum fibrinogen can be used as a new predictor of reduced BMD in menopausal women.

Abstract
Abstract Objective To study the mechanism of rib fracture caused by landing on different parts of the trunk using finite element method, and to provide some new techniques and new ideas for the reconstruction of the whole process of falls from height. Methods The finite element method was used to study the rib fracture of human security model THUMS4.0 caused by landing on different parts of the trunk. Then the model was compared with actual cases and the mechanism of rib fracture caused by falls from height was analyzed from a biomechanical point of view. Results There were some differences in the stress and strain distribution as well as the rib fracture sites when different parts touched the ground. Ribs on both sides of the body were fractured when the front of the trunk touched the ground, and the fractures were mainly located in the junction of the ribs and costal cartilage and the midaxillary line area. When the right anterior part of the trunk touched the ground, rib fracture occurred first on the side that touched the ground, and rib fractures were mainly located in the area from the right midaxillary line to the posterior axillary line, and junction of ribs on both sides and costal cartilage. When the back of the trunk touched the ground, the fracture sites were mainly located on the back of the ribs on both sides. When the right posterior part of the trunk touched the ground, multiple rib fractures were likely to occur in the parts that touched the ground. The plastic strains were mainly concentrated at the fracture sites, while the von Mises stresses were not only concentrated at the fracture sites, but also at other sites. Conclusion There are some differences in rib fracture location sites and injury mechanisms when different parts of the trunk touch the ground.

Abstract
Objective: Based on the data of chronic diseases and nutrition surveillance among Chinese adults in 2015, dyslipidemia and related factors were analyzed. Methods: Multi-stage stratified cluster random sampling was used to select participants who were aged 18 and over, with questionnaire survey and related measurements conducted. Prevalence rates of dyslipidemia among participants by different characteristics and influencing factors were analyzed, using the method of complex weighting and post-weighted stratification. Results: In all, 7 404 participants were included. The overall prevalence of dyslipidemia was 30.5% among the adults. The overall prevalence of dyslipidemia were 36.5% in males and 24.4% in females (P<0.05). The prevalence rates of hypercholesterolemia, hypertriglyceridemia, high LDL-C, and low HDL-C were 3.7%, 12.2%, 5.3%, and 19.4%, respectively. Results from the multivariate logistic regression model analysis showed that age (OR=1.009, 95%CI: 1.000-1.018), female (OR=0.501, 95%CI: 0.397-0.632), College degree or above (OR=1.728, 95%CI: 1.257-2.374), alcohol consumption 3 (OR=0.711, 95%CI: 0.536-0.943), central obesity (OR=1.868, 95%CI: 1.547-2.257), BMI (OR=1.141, 95%CI: 1.098-1.186), hypertension (OR=1.259, 95%CI: 1.077-1.473) and diabetes (OR=2.025, 95%CI: 1.446-2.835) were influencing factors on dyslipidemia. Conclusions: The prevalence of dyslipidemia seemed high among adults in Anhui. Risk factors should be closely monitored and under control, including those people with unhealthy lifestyles or being overweight, obesity, hypertensive and diabetic.

Abstract
Objective To assess the accuracy and reliability of the two 3D measuring methods, structured-light scanning and single-camera photogrammetry in forensic body surface damage and scar measurement. Methods The measuring results of 86 injuries by the ruler method, structured-light scanning and single-camera photogrammetry were compared and evaluated. The area measuring results of 13 simulated scars by the structured-light scanning, single-camera photogrammetry, Photoshop lasso pixel method and PDF reading software were compared and evaluated. The time consumed was recorded. The known specification information of the stickers was used as the standard value to compare the measuring accuracy of the ruler method, structural-light scanning and single-camera photogrammetry, and to calculate the root mean square error (RMSE). The consistency evaluation of intraclass correlation coefficient (ICC) for the repeatability of 3 measuring results obtained by different operators and the same operator. Results The differences in results of the two 3D measuring methods and the ruler method had no statistical significance; the differences between measuring results made by the structured-light scanning, single-camera photogrammetry and PDF reading software and that of the Photoshop lasso pixel method had no statistical significance. The post-processing of the single-camera photogrammetry consumed more time than that of other methods. When the long-distance group (10-40 cm) was measured, the results obtained by the ruler method were shorter than the standard value. The RMSE value results were structured-light scanning < single-camera photogrammetry < ruler method. The ICC value intragroup and intergroup were greater than 0.99. Conclusion Both structured-light scanning and single-camera photogrammetry can be applied in recording and measuring forensic body surface damage. The former has better performance in measurement accuracy and stability, while the latter has better color performance but longer post-processing time.

Abstract
Cottonseed meal (CSM), which is an unconventional protein material with abundant sources, high protein content, and a relatively cheap price, can be used in poultry diets. The aim of this study was to investigate the effects of CSM on slaughter performance, meat quality and meat chemical composition in Jiangnan White goslings. A total of 300 healthy 28-day-old male goslings were randomly divided into 5 treatments, with 6 pens containing 10 geese each. Five isonitrogenous and isocaloric experimental diets were formulated such that 0% (a corn-soybean meal basal diet, control), 25% (CSM25), 50% (CSM50), 75% (CSM75), and 100% (CSM100) protein from soybean meal was replaced with CSM (corresponding to 0, 6.73, 13.46, 20.18, and 26.91% CSM in the feed, respectively). On day 70, 1 goose from each pen (6 geese per treatment) was randomly selected and killed to measure the slaughter performance, meat quality, and the meat amino acid (AA) and fatty acid (FA) compositions. The results showed that dietary CSM did not affect the slaughter performance or meat quality of geese (P > 0.05). The fat content of breast muscle in the CSM100 group was higher than that in the control group (P < 0.05). A concentration of 13.46% or more dietary CSM increased the threonine content but decreased the cysteine content, and 20.18% dietary CSM also decreased the valine content (P < 0.05). Dietary CSM concentration had no effect on the content of total saturated FAs (SFAs, P > 0.05), but 20.18 and 26.91% dietary CSM increased the content of total monounsaturated FAs and decreased the content of total polyunsaturated FAs (PUFAs) and PUFA/SFA in the breast muscle of geese (P < 0.05). In conclusion, dietary CSM did not affect the slaughter performance or meat quality of geese, but the replacement of soybean meal with CSM in whole or high proportion altered the composition of AAs and FAs in breast muscle.

Abstract
Colorectal carcinoma (CRC) is the third most common malignancy in adults. Pediatric colorectal carcinoma (PCRC) is a rare non-embryonal tumor with a significantly lower incidence compared to adults. The clinical manifestations of PCRC are not typical, and pediatricians usually have no enough experience in diagnosis and treatment. Therefore, early diagnosis is extremely difficult, which would always lead to late clinical stages when diagnosis is made. At present, the pathogenesis of PCRC is still not clear, and many countries have started to carry out researches at the level of genes, molecules and cells. In both tumor primary tumors and distant metastases, PCRC has obvious difference in distribution from adults, and the proportion of pathological type of mucous adenocarcinoma (including the signet ring cell carcinoma) was significantly higher than that of adults. Although treated according to adult colorectal cancer guidelines, PCRC has been unable to achieve ideal efficacy with poor prognosis and lower long-term survival rate. The purpose of this paper is to summarize the epidemiological characteristics, pathogenesis, clinical symptoms, pathological types, treatment and prognosis of colorectal cancer in children by reviewing the latest literatures at home and abroad.

Abstract
Abstract Postmortem changes on corpses appear immediately after death, and can transform the original structure characteristics of the corpse to different degrees as well as show specific changes on computed tomography (CT) images, sometimes with false positives and false negatives, influencing the identification of injuries or diseases. This paper systematically summarizes the postmortem changes of computed tomography imaging characteristics on corpses, to further expand the application of virtopsy in the practices of forensic pathology identification, and provide reference for the identification of injuries, diseases and changes after normal death.

Abstract
Objective: To understand the prevalence, diagnosis and treatment of chronic critical illness (CCI) in China. Methods: The clinical data of 472 adult patients admitted to ICU in 53 hospitals, including basic information, disease-related data, nutrition program, etc., were collected on May 10, 2019, by means of multi-center cross-sectional study. If surgical intervention was needed or the occurrence of the disease was directly related to the surgery, ICU patients were regarded as surgical ICU cases (n=211). In this study, the diagnostic criteria for CCI were: (1) admission to ICU >14 days;(2) combined with persistent organ dysfunction. The prevalence,distribution and treatment of CCI and surgery-related CCI were recorded and analyzed. The Mann-Whitney U test, chi-square test or Fisher exact test were used for comparative analysis. Results: Among the 472 ICU patients from 53 hospitals, 326 were male (69.1%) and 146 were female (30.9%). The prevalence of CCI was 30.7% (145/472). Among 211 surgery-related ICU patients, 57 developed CCI with a prevalence of 27.0%. As compared to non-CCI patients, higher APACHE II score [median (IQR) 13.5 (10.0, 18.3) vs. 11.0 (7.0, 16.0), U=2970.000, P=0.007], higher Charlson comorbidity index [median (IQR) 4.0 (2.0, 7.0) vs. 3.0 (1.0, 5.0), U= 3570.000, P=0.036] and higher ratio of breath dysfunction [68.4% (39/57) vs. 48.1% (74/154), χ(2)=6.939, P=0.008] and renal dysfunction [42.1% (24/57) vs. 18.2% (28/154), χ(2)=12.821, P<0.001] were found in surgery-related CCI patients. While SOFA score, Glasgow coma score and other visceral function were not significantly different between surgery-related CCI and non-CCI patients (all P>0.05). NUTRIC score showed that surgery-related CCI patients had higher nutritional risk [43.9% (25/57) vs. 26.6%(41/154), U=5.750, P=0.016] and higher ratio of mechanical ventilation [66.7% (38/57) vs. 52.3% (79/154), χ(2)=3.977, P=0.046] than non-CCI patients. On the survey day, the daily caloric requirements of 50.2% (106/211) of surgery-related ICU patients were calculated according to the standard adult caloric intake index (104.6 to 125.5 kJ·kg(-1)·d(-1), 1 kJ=0.239 kcal), and the daily caloric requirements of 46.4% (98/211) of patients were calculated by physicians according to the severity of the patient's condition. 60.2% (127/211) of nutritional support therapy was enteral nutrition (including a combination of enteral and parenteral nutrition), while the remaining patients received parenteral nutrition (24.6%, 52/211), simple glucose infusion (9.0%, 19/211), or oral diet (6.2%, 13/211). The target calorie of CCI group was 104.6 (87.9, 125.5) kJ·kg(-1)·d(-1), and the actual calorie intake accounted for 0.98 (0.80, 1.00) of the target calory. In the non-CCI group, the target calorie was 104.6 (87.9, 125.5) kJ·kg(-1)·d(-1), and the actual calorie consumed accounted for 0.91 (0.66, 1.00) of the target calorie. There was no statistically significant difference between two groups (P=0.248, P=0.150). Conclusion: The prevalence of CCI and surgery-related CCI in ICU is high, along with severe complications, respiratory and renal dysfunction and mechanical ventilation. Surgical patients admitted to ICU are at high nutritional risk, and active and correct nutritional support is essential for such patients.

Methods Frozen specimens of human brain, myocardium and liver tissues as well as FFPE samples at different postmortem intervals were collected and mass concentration of RNA was extracted and detected. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) technology was used to analyze the amplification efficiency and relative expression of each RNA marker. Results The mass concentration and integrity of RNA extracted from FFPE samples were relatively low compared with frozen specimens. The amplification efficiency of RNA markers was related with RNA species and the length of amplification products. Among them, glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and β-actin (ACTB) with relatively long amplification products failed to achieve optimal amplification efficiency, whereas 5S ribosomal RNA (5S rRNA) achieved ideal amplification efficiency and showed quite stable expression across various tissues, therefore it was chosen as internal reference marker. The expression quantity of GAPDH and ACTB in frozen specimens with longer postmortem intervals and in FFPE samples with relatively long amplification products was decreased. The expressions of tissue-specific microRNAs (miRNAs), GAPDH and ACTB with relatively short amplification products had consistency in the same tissues and FFPE samples. Conclusion Through standardizing the RT-qPCR experiment, selecting the appropriate RNA marker and designing primers of appropriate product length, RNA expression levels of FFPE samples can be accurately quantified.

Abstract
Abstract Dead bodies found in the water are not all caused by drowning. The important task of forensic identification is to distinguish between entering the water before and after death, and to clarify the cause of death. In the practice of forensic identification, drowning is generally diagnosed on the basis of comprehensive considerations such as cadaveric signs, histopathological examinations, and diatom tests, with the exclusion of other causes of death. The emergence of virtopsy techniques provides new insights for the diagnosis of drowning. This paper reviews the post-mortem imaging studies of sinus and mastoid small chambers, respiratory tracts, lung tissues, gastrointestinal tracts and blood in the corpses in recent years. The value, potential of virtopsy in the diagnosis of drowning is discussed, with the prospects of its development direction.

Abstract
Currently, there exists an urgent need to investigate the anti-cancer effects of lidocaine on gastric cancer cells. The purpose of the present study was to evaluate the anti-tumor effects and the underlying mechanisms of lidocaine in gastric cancer cells. Our results indicated that lidocaine significantly suppressed proliferation, migration and invasion and induced apoptosis in a dose-dependently manner in human gastric cancer cells. In addition, our data shown that the expression of Bcl-2 was decreased and the level of Bax was increased by lidocaine treatment. Furthermore, we found that lidocaine altered the protein expression of the MAPK pathway. p-p38 was also increased simultaneously, while the level of p38 was not changed. In summary, lidocaine has a prominent anti-tumor activity on gastric cancer cells and is a promising therapeutic agent for the treatment of gastric cancer (Fig. 4, Ref. 32). Keywords: lidocaine, gastric cancer cells, anti-tumor effect, MAPK pathway.

Abstract
Objective: To explore the effects of vitamin D3 on intestinal mucosal barrier of mice with severe burns. Methods: Forty-two C57BL/6C male mice aged eight to twelve weeks were divided into vitamin D3 vehicle+ sham injury group of seven mice, vitamin D3 vehicle+ burn injury group of fourteen mice, vitamin D3+ sham injury group of seven mice, and vitamin D3+ burn injury group of fourteen mice according to random number table. Mice in vitamin D3 vehicle+ sham injury group and vitamin D3 vehicle+ burn injury group were injected with vehicle of vitamin D3 at a dose of 0.1 mL intraperitoneally at 1, 24, and 48 h before burn experiment. Mice in vitamin D3+ sham injury group and vitamin D3+ burn injury group were injected with vitamin D3 at a dose of 100 ng/kg dissolved in 0.1 mL vehicle intraperitoneally at the same time points. Mice in vitamin D3 vehicle+ burn injury group and vitamin D3+ burn injury group were inflicted with 30% total body surface area full-thickness dermal scald (hereinafter referred to as burn) on the back by 98 ℃ hot water for 3 to 4 seconds. And mice in vitamin D3 vehicle+ sham injury group and vitamin D3+ sham injury were treated with 37 ℃ water on the back for 3 to 4 seconds to simulate injury. Seven mice in vitamin D3 vehicle+ sham injury group and seven mice in vitamin D3+ sham injury group at post injury hour (PIH) 24, and seven mice in vitamin D3 vehicle+ burn injury group and seven mice in vitamin D3+ burn injury group at PIH 6 and 24 were sacrificed respectively to collect mesentery lymph nodes, spleens, livers, and intestinal tissue. The mesentery lymph nodes, spleens, and livers of mice in each group were collected to observe growth of bacteria, and number of bacteria was counted. Intestinal tissue of mice in each group was collected to detect protein expressions of zonal occludin 1 (ZO-1) and occludin by immunohistochemistry staining method, distribution of ZO-1 by immunofluorescence staining method, and expression of occludin by Western blotting. Data were processed with Kruskal-Wallis H test, Nemenyi test, one-way analysis of variance, t test, and Bonferroni correction. Results: (1) At PIH 6 and 24, bacterial counts of mesentery lymph nodes, livers, and spleens of mice in vitamin D3 vehicle+ burn injury group were significantly higher than those of mice in vitamin D3 vehicle+ sham injury group (P<0.05). At PIH 6, bacterial counts of livers and spleens of mice in vitamin D3+ burn injury group were significantly lower than those of mice in vitamin D3 vehicle+ burn injury group (P<0.05). At PIH 24, bacterial counts of mesentery lymph nodes and livers of mice in vitamin D3+ burn injury group were significantly lower than those of mice in vitamin D3 vehicle+ burn injury group (P<0.05). (2) At PIH 6 and 24, expressions of ZO-1 and occludin of intestinal tissue of mice in vitamin D3 vehicle+ burn injury group were significantly lower than those of mice in vitamin D3 vehicle+ sham injury group, and expressions of ZO-1 and occludin of intestinal tissue of mice in vitamin D3+ burn injury group were close to those of mice in vitamin D3+ sham injury group. At PIH 6 and 24, expressions of ZO-1 and occludin of intestinal tissue of mice in vitamin D3+ burn injury group were significantly higher than those of mice in vitamin D3 vehicle+ burn injury group. (3) At PIH 6 and 24, compared with that of mice in vitamin D3 vehicle+ sham injury group, distribution of ZO-1 of intestinal mucosal epithelium of mice in vitamin D3 vehicle+ burn injury group was discontinuous. Distribution of ZO-1 of intestinal mucosal epithelium of mice in vitamin D3+ sham injury group was normal, and the distribution of ZO-1 of intestinal mucosal epithelium of mice in vitamin D3+ burn injury group was with good continuity. (4) At PIH 6 and 24, expressions of occludin of intestinal tissue of mice in vitamin D3 vehicle+ burn injury group were 0.720±0.003, 0.638±0.052 respectively, significantly lower than 0.918±0.003 of mice in vitamin D3 vehicle+ sham injury group (t=57.33, 5.36, P<0.05). At PIH 6 and 24, expressions of occludin of intestinal tissue of mice in vitamin D3+ burn injury group were 0.994±0.058, 1.064±0.060, close to 0.938±0.023 of mice in vitamin D3+ sham injury group (t=0.91, 1.96, P>0.05). At PIH 6 and 24, expressions of occludin of intestinal tissue of mice in vitamin D3 vehicle+ burn injury group were significantly lower than those of mice in vitamin D3+ burn injury group (t=4.75, 5.35, P<0.05). Conclusions: Intestinal bacterial translocation can occur in the early stage of severe burn. And vitamin D3 plays a protective role in the intestinal mucosal barrier post severe burn to reduce the bacterial translocation by protecting tight junction proteins of intestinal epithelium.

Abstract
Objective: To investigate the relationship between duration of sleep and all-cause mortality in patients with type 2 diabetes. Methods: A total of 17 452 type 2 diabetic patients who were under the National Basic Public Health Service Project, in Changshu county, Qinghe district and Huai'an district in Huai'an city of Jiangsu province, were recruited as participants. Cox proportional hazards regression models were used to estimate the associations between different levels on the duration of sleep and all-cause mortality. Stratified analysis was performed according to factors as gender, age, and lifestyle. Results: Among the 67 912 person-years of observation, from the fo1low- up program, the median time of follow-up was 4 years, with 1 057 deaths occurred during the follow-up period. Taking patients with duration of sleep as 7 h/d for reference, the multivariate adjusted hazard ratios (95%CI) of all-cause mortality appeared as ≤6, 8, 9 and ≥10 h/d were 1.14 (0.94-1.37), 1.10 (0.91-1.32), 1.33 (1.05-1.70), and 1.52 (1.24-1.87), respectively which were associated with the duration of sleep. Data from the subgroup analysis showed that this was consistent with the whole population. Longer duration of sleep was associated with the all-cause mortality but no significant association was found between shorter duration of sleep and the all-cause mortality. Conclusion: Longer duration of sleep seemed to have increased the risk of all-cause mortality in type 2 diabetic patients.

Methods: As a retrospective study, clinical data, laboratory test results and MSUS results of 22 joints (2 wrist joints, 10 metacarpophalangeal joints, 2 thumb interphalangeal joints, 8 proximal interphalangeal joints) were collected from 403 hospitalized RA patients (including Han and Uygur patients) in the People's Hospital of the Xinjiang Uygur Autonomous Region from January 2016 to December 2016. Result: (1) There was a positive correlation between swollen joints count, tender joints count, erythrocyte sedimentation rate, C-reaction protein and sum scores of articular cavity effusion, Grey Scale (GS), Power Doppler (PD), tenosynovitis in RA patients; (2)there was a positive correlation between DAS28-ESR, DAS28-CRP, SDAI, CDAI and sum scores of effusion, GS, PD, tenosynovitis in RA patients. The ulnar extensor tendon of the wrist of RA patients was more susceptible to extensor tendon than other extensor tendons; (3)there was significant statistical difference between Uygur and Han RA patients in bone erosion (P<0.05), however the statistical difference between Uygur and Han RA patients in effusion, GS or PD score was not significant (P>0.05). Few Uygur RA patients achieved clinical remission and subclinical synovitis was not detected, while such subclinical synovitis was detected in Han RA patients who achieved clinical remission. Conclusion: The MUSU can assess the disease activity of RA patients, and provide a more direct and objective evidence for the rapid evaluation of disease.

Abstract
Objective: To investigate the prognostic effect of neonatal morbidities on poor outcomes at 12 months corrected age in very low birth weight (VLBW) premature infants . Method: From November 2013 to October 2014, a multi-center retrospective study was conducted in 8 tertiary Maternal and Children's hospitals in Guangdong, Hunan and Fujian. The premature infants survived to a postmenstrual age (PMA) of 36 weeks with birth weight less than 1 500 g and without congenital diseases were included, and divided into two groups according to poor outcomes. The birth weight, gestational age, morbidities and poor outcomes (death, cerebral palsy, cognitive delay, et al) were recorded. Data were analyzed with Chi-square test to investigate the relationship between morbidities and poor outcomes. And the predictive effect of the top three morbidities were analyzed by Logistic regression analysis. Result: Total of 834 VLBW premature infants (473 boys and 361 girls) finished the follow-up, whose average gestational age and birth weight were (30.6±1.8) weeks and (1 189±159)g. The incidences of BPD, severe ROP, NEC, brain injury and sepsis were 207 (24.8%), 119 (14.3%), 58 (7.0%), 281 (33.7%) and 124 (14.9%), respectively. There were significant differences between the two groups in the incidences of BPD, severe ROP, NEC, brain injury and sepsis(χ(2)=42.10, 47.20, 4.81, 44.28, 18.63, all P<0.01), which had significant correlation with poor outcomes at 12 months corrected age. The three top morbidities were severe ROP, BPD and brain injury(OR=3.82, 2.90, 2.80). Combined morbidities with BPD, severe ROP and brain injury correlated with higher risk of poor outcomes (one morbidity, OR=3.14, β=1.15; two morbidities, OR=7.31, β=1.99; three morbidities, OR=22.41, β=3.11; all P<0.01). Conclusion: BPD, severe ROP, NEC, brain injury and sepsis were the risk factors of poor outcomes at 12 months corrected age in VLBW infants. And the more combined morbidities with severe ROP, BPD and brain injury, the higher risk of poor outcomes in this population. Trial registration Clinical Trails, NCT03104946.

Abstract
OBJECTIVES To use virtual anatomy technique in the analysis of post-mortem characteristic changes of CT images in the experimental drowning rabbit model and the related parameters in 3D virtual model, so as to explore its application value in the diagnosis of drowning in forensic pathology. METHODS A model of drowning rabbits was established, with animal models of hemorrhagic shock and mechanical asphyxia as the controls. CT scan was performed on the experimental animals, and the differences in imaging features between the groups were compared by morphological reading of the tomographic images. CT data were imported into Mimics 14.0 software for 3D modeling. The CT values and lung volumes were calculated by the software, and the differences on CT values and lung volumes brought by different causes of death were analyzed. RESULTS The CT images of lungs in the drowning group showed characteristic ground-glass opacity (diffuse and uniform density increase). There were no obvious abnormalities in hemorrhagic shock group, and only a few similar changes were found in the mechanical asphyxia group. Compared with the controls, the CT values and the lung volumes in the drowning group were significantly increased P<0.05. CONCLUSIONS Based on post-mortem lung imaging, the combination of CT value and lung volume changes can effectively reflect the virtual anatomical features in drowning, and provide a diagnostic basis for the forensic identification of drowning.

Abstract
BACKGROUND Chronic thromboembolic pulmonary hypertension (CTEPH) is classified as group IV pulmonary hypertension. This study aimed to report our institutional experience in managing CTEPH. METHODS We prospectively collected the data of 23 patients diagnosed with CTEPH between August 2001 and August 2017 in Linkou Chang Gung Memorial Hospital. Baseline characteristics including functional class (FC), 6-minute walk distance (6MWD), comorbidities, hematological and biochemical data, echocardiography, cardiac catheterization, and selective pulmonary angiography were recorded at diagnosis. All patients were referred to a cardiac surgeon for pulmonary endarterectomy (PEA) assessment. RESULTS The mean age at diagnosis was 48.4 ± 16.1 years. Nineteen patients (83%) underwent PEA with mean postoperative follow-up of 37.7 ± 42.8 months. The in-hospital mortality rate of PEA was 11%. The 1-, 2-, 3- and 5-year overall survival rates were 89%, 89%, 81%, and 50%, respectively. After 3 months of PEA, all patients had improvements in FC, 6MWD (from 326 ± 62 to 420 ± 63 m), B-type natriuretic peptide level (from 602 ± 599 to 268 ± 565 pg/mL), and systolic pulmonary artery pressure (from 79 ± 19 to 48 ± 19 mmHg). The patients with proximal disease (Jamieson type 1 or 2) had better survival than those with distal disease (Jamieson type 3 or 4), but there was no significant difference in mortality between FC III and IV. All of the four patients who did not undergo PEA survived for more than 3 years. CONCLUSIONS Significant improvements in symptoms, functional capacity, and hemodynamics were achieved in the CTEPH patients after PEA. However, the overall survival was still unsatisfactory.

Abstract
Objective: To understand and evaluate the characteristics of geographic distribution of high blood pressure prevalence in children and adolescents aged 7-18 years in China in 2014, and provide evidence for the prevention of hypertension in children and adolescents. Methods: The data of 2014 Chinese National Surveys on Students Constitution and Health conducting 31 provinces (except Hong Kong, Macao and Taiwan) were collected. A total of 216 299 children and adolescents who had complete blood pressure records were selected as study subjects. The low, middle and high prevalence areas were identified according to their high blood pressure detection rates in the children and adolescents,<4%, 4%-7% and >7%, to analyze the geographic distribution of high blood pressure prevalence in the children and adolescents. The environmental data in the capitals of 31 provinces in 2014 were collected to analyze the correlation between environmental factors and blood pressure Z score in the children and adolescents. Results: The average detection rates of high blood pressure was 6.4% in 31 provinces (1.5%-14.2%). The high prevalence areas were mainly distributed in the eastern China, especially the Circum-Bohai sea area, low prevalence areas were mainly distributed in the central and western areas of China and some provinces in the east. Correlation analysis results showed that the annual average temperature, annual average air humidity and local altitude were negatively correlated with blood pressure Z score, including diastolic and systolic blood pressure, in both boys and girls. The annual average sunshine time, PM(2.5) and PM(10) concentrations, content of SO(2) were positively correlated with blood pressure Z score in both boys and girls. Conclusions: There was a significant difference in high blood pressure of children and adolescents among 31 provinces. More attention should be paid to the children and adolescents living high prevalence area. And it is necessary to understand environmental factors which can affect the blood pressure of children and adolescents.

Abstract
Frequency conversion forms an integral block of the electronic circuits used in various applications including energy harvesting, communications and signal processing. These frequency conversion units however require external power sources and occupy a large device footprint making it difficult to be integrated in micro-circuits. Here we demonstrate that nanoscale magnetic tunnel junctions can act as frequency converters without an external power supply or DC bias source. The device directly mixes an external microwave signal with the internal spin precession oscillations to create new frequencies tunable by an external magnetic field in a single device with a small device footprint. We observe up-conversion and down-conversion of the input signal for excitation frequencies between 2 GHz and 6 GHz. We also show that the device acts as a zero-bias rectifier that can generate voltages exceeding 12 mV when the excitation frequency matches the natural oscillations mode of the device.

Abstract
Objective: To evaluate the influence of fracture resistance of endodontically treated teeth with different thickness of ferrule by mechanical fatigue test and static loading test, and so as to provide a reference for the clinical treatment planning. Methods: Fifty bovine incisors were divided into 5 groups by random number table method (n=10). Group A was the control group in which the incisors were prepared without a ferrule design (0 mm). The other four groups (B, C, D, E) were experimental groups, and the thickness of the dentin ferrule prepared for specimens in each group was 0.5, 1.0, 1.5, and 2.0 mm. The height of ferrules in all the specimens was 2 mm. Cyclic fatigue loading (2.33 Hz, 50 N) was applied on each specimen until either the specimen was dislodged/fractured or the 300 000 cycles were finished. After fatigue loading, the mode of failure was observed. Those intact specimen after fatigue loading were tested under a gradually increasing force using a universal testing machine (0.05 mm/min) until fracture occurred. The forces required to fracture and failure model was recorded. Results: The results of cyclic loading tests showed that: all specimens survived the 300 000 cycles of intermittent loading. The results of static loading tests showed that: the fracture force of A, B, C, D and E groups respectively were (226.4±67.7), (369.7±34.5), (400.7±48.2), (528.1±56.3), and (555.4±98.5) N (F=15.227, P=0.000). There was a significant difference in fracture resistance between group A and the other four groups, and between group B, C and group D, E (P<0.05). No statistical difference were found in fracture resistance among the other groups (P>0.05). There was strong correlation between the thickness of ferrule and the fracture force by Pearson correlation analysis (r=0.973, P=0.002). Conclusions: Within the limitations of this study, the following conclusions can be drawn: The different thickness of ferrule can influence the fracture resistance of the teeth, and when the height of the ferrule is 2.0 mm, the fracture force increased significantly with an increasing ferrule thickness.

Abstract
Chronic rhinosinusitis with or without nasal polyps mainly uses combination of medications represented by nasal glucocorticoids and functional sinus endoscopic surgery (FESS) and comprehensive treatment with antibiotics. The effect of oral antibiotics for CRS exacerbations on the microbial resistance rate in the population has not yet been fully assessed, but may be significant, and glucocorticoid-resistant CRS has also emerged. CRSwNP associated with complications of asthma is considered a more serious condition. It can have a major impact on the patient's quality of life. Therefore, there seems to be an urgent need for new strategies, including biologics to treat this common disease. Usually there is a TH2 bias in refractory CRS. Recently, studies of biologics have played a different role in severe airway disease, especially in Th2-biased CRSwNP, which opens up a new treatment approach compared with standard therapy. Biological therapy may help to improve patients with refractory CRSwNP clinical outcomes. Biological agents include monoclonal antibodies, cytokines, or receptors. Monoclonal antibodies currently available for the treatment of refractory CRS include omalizumab, mepolizumab, reslizumab, benralizumab, dupilumab, etc. This article describes the progress made in the treatment of chronic rhinosinusitis with or without nasal polyps with several monoclonal antibodies.

Abstract
Objective: To explore the associations between exposure to chlorination disinfection by-products (CDBPs) during gestation and newborns' small for gestational age (SGA). Methods: During April 2010 to July 2012, a total of 3 903 pregnant women who lived in a district with the same water treatment plant in Wuhan, China were recruited to this perspective study. Information about demographic characteristics of pregnant women and their newborns was collected. The tap water samples were monthly collected for 28 months in 3 different sites, with 84 samples, and 4 kinds of trihalomethanes (THMs)(chloroform (TCM), bromodichloromethane (BDCM), dibromochloromethane (DBCM), and bromoform (TBM)) and 2 kinds of chlorohaloacetic acids (HAAs) (trichloroacetic acid (TCAA), dichloroacetic acid (DCAA)) were determined. The pregnant women were divided into 4 groups(Q1 to Q4) by quartile method according to their exposure level of CDBPs. Binary Logistic regression models were used to assess the associations between exposure to CDBPs during gestation and newborns' small for gestational age. Results: The average weight of all the newborns was (3 310.19±389.91) g, of which 169 (4.33%) were SGA. The median concentrations of TCM, BDCM, bromo-THMs, total THMs, TCAA, and DCAA during the whole pregnancy were 18.07, 4.93, 8.51, 26.74, 10.65, and 13.77 μg/L, respectively. Binary Logistic regression analysis showed dose-response relationships between elevated TCM and total THMs during the whole gestation and compared with Q1 group, while there was a increased risk of SGA in Q4 group, and OR(95%CI) was 1.87 (1.01-3.49) , 2.30 (1.22-4.35) , respectively (P for trend equaled to 0.044, 0.015). Compare with Q1 group, there also be positive associations between exposure to TCAA (Q4 group) during first-trimester and the whole gestation and SGA, while OR(95%CI) was 2.16 (1.19-3.91) (P for trend equaled to 0.015). Conclusion: Exposure to CDBPs during gestation might increase the risk of newborns' SGA.

Abstract
Objective: This study aimed to explore the association between malnutrition and the level of blood pressure (BP) as well as elevated BP (EBP) in Han students aged 7 to 18 years in China. Methods: 170 037 subjects with normal nutritional status and malnutrition were enrolled in this study from 2014 Chinese National Surveys on Students' Constitution and Health with a multi-stage stratified cluster random sampling framework covering 31 provinces, autonomous regions and municipalities after the exclusion of 44 317 overweight and obese students. According to the standard of "Screening Standard for Malnutrition of School-age Children and Adolescents" (WS/T456-2014), the nutritional status of children were classified into two categories, normal nutritional status and malnutrition containing stunting, mild wasting and moderate severe wasting. The level of BP and prevalence of EBP were compared between students with normal nutritional status and malnutrition. The multivariate logistic regression model was used to analyze the association between malnutrition and EBP. Results: The levels of systolic BP (SBP) and diastolic BP (DBP) in Chinese Han students aged 7-18 years who were non-overweight and non-obesity status were (103.4±12.3) and (64.7±9.5) mmHg (1 mmHg=0.133 kPa), respectively. The prevalence of EBP, systolic EBP and diastolic EBP in Chinese Han malnourished students (N=21 012) were 3.1% (n=649), 1.5% (n=324) and 2.1% (n=445), respectively, which was significantly lower than those (N=148 320) with normal nutritional status (4.5% (n=6 707), 2.6% (n=3 872) and 2.7% (n=3 959)), and the corresponding differences were statistically significant (P<0.05). The OR (95%CI) between malnutrition and EBP was 0.68 (0.62-0.73), which were 0.65 (0.58-0.72) and 0.68 (0.60-0.77) for boys and girls. The OR (95%CI) between EBP and stunting as well as mild wasting and moderate severe wasting were 0.69 (0.62-0.77), 0.63 (0.55-0.72) and 0.79 (0.60-1.05), respectively. Conclusion: The level of BP and prevalence of EBP in Chinese Han students with malnutrition were lower than those with normal nutritional status.

Abstract
Objective: To analyze the prevalence of physical fitness among Chinese Han students aged 13-18 years in 2014, and explore related influencing factors. Methods: This study recruited 106 881 Han students aged 13-18 years who had taken physical fitness test from Chinese National Survey on Students' Constitution and Health in 2014. After the exclusion of 1 047 students without complete records of physical fitness test, 105 834 students were included in the final analysis. According to the National Student Physical Health Standard modified in 2014, seven indicators including body mass index, vital capacity, 50-m run, sit-and-reach, standing broad jump, pull-ups/curl-ups and endurance run were tested to calculate the total score of students' physical fitness. Students with score ≥60 were regarded as qualified students. Multivariate non-conditional logistic regression model was used to analyze influencing factors of physical fitness. Results: Among Chinese Han students aged 13-18 years, the total score was 70.1±10.7 and the qualified rate was 83.9% (n=88 813). Boys (83.5% (44 197/52 910)) had a lower qualified rate of physical fitness than girls (84.3% (44 616/52 924)) (P<0.001), and 13-15 age group (86.5% (46 255/53 465)) was higher than the 16-18 age group (81.3% (42 558/52 369)) (P<0.001). Except for 16-18-year-old boys from central region, normal body mass index, eastern region, good socioeconomic status, enough PE class, exercise time ≥1 h/d, homework time ≥2 h/d, TV time <1 h/d were all related to high qualified rates of physical fitness (P<0.05). Conclusion: Chinese Han students aged 13-18 years were in good physical condition. The qualified rates of physical fitness were significantly different by gender and age groups. Nutritional status, region, socioeconomic status, PE class, exercise time per day, homework time per day, and TV time per day were related factors of physical fitness.

Abstract
Objective: To analyze the expression of soluble programmed death ligand 1 (sPD-L1) in the serum of patients with advanced epidermal growth factor receptor (EGFR) mutated lung adenocarcinoma and to explore its clinical implications. Methods: Seventy-two patients with EGFR mutated advanced lung adenocarcinoma (EGFR mutation group) were included from the Department of Respiratory Diseases in The Second Affiliated Hospital of Soochow University from May 2015 to July 2016. Thirty-one patients with advanced EGFR wild type (WT) lung adenocarcinoma [EGFR WT group, diagnosed via mini specimens from bronchoscopy or transthoracic needle aspiration biopsy (TNAB), matching in sex, age and tumor stage with EGFR mutation group] were also enrolled as controls. The sPD-L1 protein expression in serum was determined by enzyme-linked immunosorbent assay (ELISA) kit. According to the clinical response of two-month EGFR-tyrosine kinase inhibitor (TKI) treatment, all patients were divided into two groups: 36 cases in disease progression groups (PD group) and 36 cases in disease control group (DC group). The sPD-L1 level in peripheral blood between the two groups was analyzed. In EGFR mutation group, the relationship of serum sPD-L1 with TNM staging was analyzed. At the same time, the value of serum sPD-L1 and cancer embryo antigen (CEA) in clinical evaluation of advanced EGFR mutated lung adenocarcinoma was evaluated by analyzing the receiver operating characteristic (ROC) curve. Results: A lower level of sPD-L1 level in EGFR mutation group [0.75(0.15-2.78) μg/L] was found compared with the control group [1.56(0.85-3.29) μg/L] (P<0.001). The expression of sPD-L1 in PD group was significantly higher than that in DC group [1.175(0.62-2.78) μg/L vs 0.625(0.15-2.27) μg/L, P<0.001]. High expression of sPD-L1 in the serum of patients with advanced EGFR mutated lung adenocarcinoma was closely correlated to lymph node metastasis and distant metastasis (χ2=10.985, 4.662; both P<0.05). The area under ROC curve of serum sPD-L1 and CEA was 0.893 (95%CI: 0.830-0.956) and 0.745(95%CI: 0.652-0.839) respectively. Youden index was the maximum when the cutoff value of sPD-L1 was set to 0.815 μg/L, and the sensitivity and specificity were 77.8% and 91.4%, respectively. Conclusions: After EGFR-TKI treatment, the level of sPD-L1 in the serum of patients with advanced EGFR mutated lung adenocarcinoma is lower, which suggests that sPD-L1 expression may depend on the regulation of EGFR signaling pathway. The level of sPD-L1 can reflect the clinical response of EGFR mutated lung adenocarcinoma to EGFR-TKI.

Abstract
Ozone (O3) is one of the major pollutants in near-surface air. In order to protect sensitive plants from O3 pollution, many kinds of protectants including synthetic ones, were assessed in previous studies. Although they have certain protective effects, some of them are not environment-friendly. In the present study, leaf water extracts of aromatic plants [Plectranthus hadiensis var. tomentosus (PHT), Pelargonium hortorum (PHB), Tagetes patula (TP)] were compared for mitigating the damages caused by O3 (150 ppb for 3 days, 8 h day-1) on snap bean (Phaseolus vulgaris 'Jiangjunyoudou'). Our results showed that O3 fumigation impaired plasma membrane, decreased chlorophyll content, increased contents of malondialdehyde and superoxide anion, inhibited photosynthesis, and caused visible injury. Leaf water extracts of PHT, PHB or TP ameliorated the negative effects of O3. Among them, extract of PHT showed the greatest potential to alleviate the O3-caused injury, followed by PHB and TP.

Abstract
OBJECTIVES To reconstruct a vehicle-bicycle-cyclist crash accident and analyse the injuries using 3D laser scanning technology, multi-rigid-body dynamics and optimized genetic algorithm, and to provide biomechanical basis for the forensic identification of death cause. METHODS The vehicle was measured by 3D laser scanning technology. The multi-rigid-body models of cyclist, bicycle and vehicle were developed based on the measurements. The value range of optimal variables was set. A multi-objective genetic algorithm and the nondominated sorting genetic algorithm were used to find the optimal solutions, which were compared to the record of the surveillance video around the accident scene. RESULTS The reconstruction result of laser scanning on vehicle was satisfactory. In the optimal solutions found by optimization method of genetic algorithm, the dynamical behaviours of dummy, bicycle and vehicle corresponded to that recorded by the surveillance video. The injury parameters of dummy were consistent with the situation and position of the real injuries on the cyclist in accident. CONCLUSIONS The motion status before accident, damage process by crash and mechanical analysis on the injury of the victim can be reconstructed using 3D laser scanning technology, multi-rigid-body dynamics and optimized genetic algorithm, which have application value in the identification of injury manner and analysis of death cause in traffic accidents.

Abstract
PURPOSE Direct location of the "safe zone" on a CT axial view is impossible because the radial head is circular in shape. Previous "safe zone" location methods are not appropriate if the physician is unable to visualize the actual radial head. This study aims to introduce a new method to locate the "safe zone" on CT. METHODS CT scans were performed on 20 intact cadaveric upper limbs from 20 different corpses in full pronation and supination. The DICOM-format raw data were then re-sliced and analyzed in Mimics 17.0 (Materialise, Belgium). The radial interosseous border (IB) is shaped like a droplet on the axial view; its axis was selected as our reference line (RL). A parallel line in the radial head axial slice was created, and its position relative to the "safe zone" was studied. Deviation in RL direction was evaluated. RESULTS Safe-zone scope was 114.41°±11.99. The rotation angle from the RL to the safe-zone's anterior and posterior border was 215.03°±5.99 and 100.62°±8.12, respectively. Rotation direction (clockwise or anti-clockwise) depended on relative radius-ulna position. The safe zone was located by determining these two borders. The reference line's direction was stable in the upper half of the IB; its distance to the radial head fovea was 77.33° mm±6.24. CONCLUSIONS The radial head "safe zone" can be located on CT axial view based on the upper half of the IB using this new method. The method is clinically applicable to determine whether postoperative elbow malrotation results from plate impingement.

Western blot was used to detect the expression of P38, p-P38 and CCR2 in spinal cord of rats. Results: At day 5, 7, 9, 14, 21 post-injection, mechanical withdrawal thresholds of group S were(30.9±1.5), (31.9±1.2), (32.0±1.1), (31.6±1.5), (32.2±1.4)g respectively, the mechanical withdrawal thresholds of group B were( 26.4±0.7), (24.4±0.8), (21.4±0.8), (13.5±0.4), (9.9±0.2)g respectively, the mechanical withdrawal thresholds in group B decreased obviously versus group S, and the differences were statistically significant(t=-13.177, -16.660, -23.778, -35.574, -48.401, all P<0.01). At day 9 post-injection, the mechanical withdrawal thresholds in SD, BD, SR and BR groups were (32.4±1.7), (19.4±1.1), (32.1±1.3), (26.3±1.0) g respectively, the difference was statistically significant (F=224.681, P<0.01), and the mechanical withdrawal thresholds in group BD decreased obviously versus group SD, while the mechanical withdrawal thresholds in group BR increased obviously versus group BD. The expression levels of p-P38 in spinal cord of group S, group B5, group B9 and group B14 were(0.08±0.03), (0.20±0.05), (0.40±0.17), (0.65±0.14)respectively, the expression levels of CCR2 were(0.08±0.04), (0.18±0.05), (0.30±0.09), (0.58±0.07)respectively, the difference was statistically significant(F=19.123, 40.746, all P<0.01), and the expression of p-P38 and CCR2 in group B9 were showed a significant up-regulation versus group S. The expression levels of p-P38 in spinal cord of group BD, group BR0.5 h, group BR4 h and group BR12 h were (0.57±0.06), (0.17±0.11), (0.03±0.01), (0.25±0.11)respectively, and the difference was statistically significant(F=29.582, P<0.01). The expression of p-P38 in group BR0.5 h, BR4 h, BR12 h showed a significant down-regulation versus group BD. Conclusion: CCR2 in the spinal cord may be involved in the development of bone cancer pain by activating P38MAPK signaling pathway in rats.

Abstract
OBJECTIVES To explore the application value of postmortem computed tomography (CT) angiography on diagnosis of coronary atherosclerotic stenosis degree. METHODS Based on the previous experimental results, the postmortem CT angiography device of human isolated heart was improved. Different coronary atherosclerotic stenosis degree of sudden death cases was selected. Before the cardiac anatomy, hearts were removed out completely and CT angiography was performed immediately. The CT angiography results were compared with histopathological findings. Meanwhile, the advantages and disadvantages of the angiography device before and after improvement were compared. RESULTS The improved angiography device of isolated heart could get better imaging results. The postmortem CT angiography results had high consistency with the histopathological findings on diagnosis of coronary atherosclerotic stenosis degree. And the coronary artery lesions could be revealed more objectively and vividly by 3D reconstruction technology. However, CT angiography could only be used to examine the pathological changes of blood vessels, which might have some limitations on the diagnosis of cause of death. CONCLUSIONS Postmortem CT angiography can be used as an additional method for the conventional autopsy in the cases of coronary atherosclerosis.

Abstract
Objective: To discuss the main causes and risk factors of disability and death among current Chinese adolescents. Methods: Subnational data of China from Global Burden of Disease Study 2015 (GBD 2015) was used to rank the causes and risk factors leading to death and disability adjusted life years (DALY) in Chinese adolescents aged between 10 and 19 years old, and thereby to analyze the main cauese and risk factors of death and DALY among Chinese adolescents in different genders. Results: In 2015, among Chinese adolescents aged 10-19 years old, the total DALY was 13 million 490 thousand years, and the total number of deaths was 63 258 cases. The top 3 causes of DALY were skin and subcutaneous diseases, iron-deficiency anemia and road injuries, resulting in DALY (constituent ratio) of 1 411 (10.5%), 1 094 (8.1%) and 1 029 (7.6%) thousand years respectively. The top 3 causes of death were road injuries, drowning and leukemia, causing 13 881 (21.9%), 9 895 (15.6%) and 4 620 (7.3%) deaths (constituent ratio) respectively. The top 3 risk factors of DALY were iron deficiency, alcohol use and drug use, causing 1 094 (8.1%), 487 (3.6%) and 220 thousand years (1.6%) DALY (constituent ratio) respectively. The top 3 risk factors of death were alcohol use, occupational injuries and drug use, causing 5 957 (9.4%), 1 523 (2.4%) and 810 (1.3%) deaths respectively. Conclusion: Unintentional injury was the top cause of DALY and death in Chinese adolescents, followed by skin and subcutaneous diseases and iron-deficiency anemia. Iron deficiency and alcohol use were the top two risk factors of DALY and death.

Abstract
In this study, impacts of O3 on four cultivars ('Rose', 'Pink', 'Blush' and 'White') of the polka dot plant with variegated leaves were investigated for the first time. Ozone fumigation [(120 ± 20 ppb) for 14 days (8 h day-1, from 8:30 to 16:30)] resulted in visible foliar injuries, decreased contents of pigments (chlorophyll a and b, and carotenoid), the inhibition of photosynthesis, the increase of quantum yield of non-regulated heat dissipation and fluorescence emission (Y(NO)), and the damage of cell membrane. Elevated O3 increased the content of anthocyanin (Ant). 'White' showed the highest, and 'Rose' the lowest amount of injured leaf area, indicating that the former was the most sensitive, and the latter the most tolerant to O3 stress. After O3 exposure, the highest Ant content was found in 'Rose', followed by 'Pink', 'Blush', and 'White'. Levels of Ant were likely responsible for the different sensitivities to O3 due to their roles in photoprotection.

Abstract
Objective: To investigate the correlation between the expression of PD-1, PD-L1 and clinicopathologic parameters in triple negative breast carcinoma (TNBC). Methods: Samples from 151 patients with TNBC and 65 cases of other breast carcinomas (non-TNBC) were examined for PD-L1 and PD-1 expression by immunohistochemical staining on tissue microarray. Results: The expression of PD-L1 and PD-1 in the tumor cells and interstitial lymphocytes in TNBC was significantly (P<0.05)higher than that in non-TNBC.In TNBC, the expression rates of PD-L1 in the cancer nests and stroma were 16.6%(25/151) and 25.2%(38/151)respectively.The former was positively correlated with tumor histological grade and lymph node metastasis (P<0.05), and the latter only with tumor histological grade (P<0.05). The expression rate of PD-1 was 27.2% (41/151), and correlated with PD-L1 expression in stromal tumor-infiltrating lymphocytes (P<0.05). Conclusion: The expression of PD-L1 in TNBC is significantly correlated with high-grade histology, lymph node metastasis and PD-L1 expression in stromal tumor-infiltrating lymphocytes.

Abstract
Objective: To investigate the effect of restraint stress on masseter mechanical hyperalgesia and the activity of neurons and astrocytes in the spinal trigeminal nucleus caudalis (Vc). Methods: The animals were randomly divided into the control group, 1-, 3-, 5-, 7-, 9-, 11-and 14-day stress groups, with 10 rats in each group. The body weight increase and behavior tests were used to testify the animal model. The mechanical sensitivity of masseter of the rat before and after the stress was measured with Von Frey filaments. Histological examinations were used to evaluate the expression of neuronal c-fos and astrocytic glial fibrillary acidic protein (GFAP). Results: Restraint stress resulted in remarkable mechanical allodynia in the masseter muscle. The head withdrawal threshold was significantly lower in the 7-, 9-, 11-and 14-day stress groups ([0.071±0.011], [0.059±0.020], [0.052±0.011], [0.033±0.011] N) than that in the control group ([0.120±0.025] N) (P<0.05). Compared to the control group, the rats in the 1-day stress group showed a significant increase of c-fos in neurons of the Vc and then declined to normal level after 1 week gradually. The GFAP expression in astrocytes of the Vc was significantly increased in the 7-, 9-, 11-and 14-day stress groups (4.3±1.0, 4.5±0.6, 4.6±0.5, 4.8±1.3) compared with the control group (2.0±0.8) (P<0.05). Conclusions: Chronic restraint stress could lower the threshold of mechanical allodynia in the masseter muscle and activate the neurons and astrocytes in Vc. The activation of neurons and astrocytes plays an important role in the masseter hyperalgesia induced by restraint stress in rats.

Abstract
This paper aimed to analyze the clinical effects of Xianling Gubao capsules on the bone mineral density (BMD) of 94 patients with osteoporosis. After reviewing and analyzing the clinical information in our hospital from January 2015 to January 2016, the patients were divided into a control group and a treatment group with 47 cases in each group. Patients in the control group were treated with routine Western medicine, while the treatment group received Xianling Gubao capsules. Both groups were treated continuously for 3 courses (30 days each course) and had their BMD analyzed and compared. The effective rates of the treatment group and control group were 91.48% and 70.21%, respectively, with statistical significance (P less than 0.05). Compared with the same group before the treatment, the bone metabolic indexes (blood calcium, phosphorus, and alkaline phosphate) and the BMD of the femoral neck and lumbar vertebrae (L1-2, L3-4, L2-4) of both groups were all improved with statistical significance (P less than 0.05) after the treatment. The above indexes of the treatment group were all significantly higher than those of the control group, with statistical significance (P less than 0.05). Compared with the same group before treatment (P less than 0.05), the osteocalcin (OC) levels of both groups were increased, and the Cross-linked N-telopeptide of type 1 collagen (CTX-1) levels were decreased after the treatment. The OC level in the treatment group was higher when compared with the control group, while the CTX-1 level was lower compared to the control group (P less than 0.05). Moreover, no significant side-effects or adverse events were observed during the treatment and observation period. The Xianling Gubao Capsule possesses a therapeutic effect for BMD in osteoporosis patients, which can effectively increase their BMD, improve their bone metabolism, and control the loss of bone mass, therefore, can be used in clinical promotion and application.
