Abstract
OBJECTIVE To evaluate the efficiency of a recombinase-aided amplification (RAA) assay for the detection of Schistosoma japonicum infections in Oncomelania hupensis snails. METHODS A group test was employed. Fifty Oncomelania snails were collected as a detection sample. The detection samples without infected snails were designated as negative specimens, while the detection samples that contained different numbers of infected snails were designated as positive specimens. A total of 10 negative specimens, 10 positive specimens containing 1 infected snail, 20 positive specimens containing 2 infected snails and 10 positive specimens containing 3 infected snails were assigned. Following random grouping, 40 specimens were subject to the florescent RAA assay using a blind method. The miradium shedding method served as a gold standard, and the sensitivity, specificity, Youden's index and coincidence rate of the florescent RAA assay were estimated. In addition, 20 samples consisted of 5 negative specimens and 15 positive specimens with 1, 2 and 3 infected snails respectively were grouped randomly. The same specimens were detected using the crushing method and fluorescent RAA assay with the blind method in a paired-design manner. Then, the test results were compared and analyzed. RESULTS Florescent RAA assay detected 29 positives in the 30 specimens containing different numbers of infected snails, with a sensitivity of 96.67%, and 8 negatives in the 10 detection specimens without infected snails, with a specificity of 80.00%, showing a Youden's index of 0.77. The coincidence rate was 100% among 10 repeated assays for a detection specimen. In addition, there was no significant difference in the detection of infected snails between the florescent RAA assay and the crushing method (χ2 = 0, P > 0.05), and the actual coincidence rates of the florescent RAA assay and crushing method were 95.00% (19/20) and 90.00% (18/20) with the real results, respectively. CONCLUSION Fluorescent RAA assay has a favorable efficiency for the detection of S. japonicum infections in Oncomelania snails, which shows a potential in screening of S. japonicum-infected Oncomelania snails.

Abstract
Litter size is one of the most important reproductive traits of sheep, which has pronounced effects on the profit of husbandry enterprises and enthusiasm of breeders. Despite the importance of litter size, the underlying genetic mechanisms have not been entirely elucidated. Therefore, based on a high-density SNP chip, genome-wide comparative analysis was performed between two groups with different fecundity to reveal candidate genes linked to litter size via detection of homozygosity and selection signatures in Luzhong mutton sheep. Consequently, nine promising genes were identified from six runs of homozygosity islands, and functionally linked to reproduction (ACTL7A, ACTL7B, and ELP1), embryonic development (KLF5 and PIBF1), and cell cycle (DACH1, BORA, DIS3, and MZT1). A total of 128 genes were observed under selection, of which HECW1 and HTR1E were related to total lambs born, GABRG3, LRP1B, and MACROD2 to teat number, and AGBL1 to reproductive seasonality. Additionally, the presence of inbreeding depression implies the urgency of reasonable mating system to increase litter size in the present herd. These findings provide a comprehensive insight to the genetic makeup of litter size, and also contribute to implementation of marker-assisted selection in sheep.

Abstract
Objective: To investigate the effectiveness of a digital virtual simulation training system applied in the preclinical teaching of access and coronal cavity preparation. Methods: Twenty dental undergraduate students from Peking University School and Hospital of Stomatology were recruited and divided randomly and equally into two groups according to the random number method after being unified with theory training, including access and coronal cavity preparation skills assessment form and Simodont system operation manual. Tests for access and coronal cavity preparation skills by using standard simulation plastic teeth were performed and the scores were recorded as baseline for each student. Students in group of virtual simulation priority were trained using Simodont virtual simulation system, while those in group of phantom-simulator priority were trained using conventional phantom-simulator system. Access and coronal cavity preparation skills of standard simulation plastic teeth were assessed once again and recorded as the second scores for the two groups. Furthermore, the two groups of students exchanged training systems and were assessed and graded once more as the third scores. Finally, all students were asked to fill up a Teaching Questionnaire after the training. The data were then collected and analyzed. Results: For the group of virtual simulation priority, after the training by using Simodont virtual simulation system and conventional phantom-simulator system, the mean score of access and coronal cavity preparation (16.00±1.49) was significantly higher than the baseline score (13.30±1.41) (P<0.05). For the group of phantom-simulator priority, after the training by using conventional phantom-simulator system and Simodont virtual simulation system, the mean score of access and coronal cavity preparation (15.60±1.26) was also significantly higher than the baseline score (13.00±1.89) (P<0.05). Furthermore, in the group of virtual simulation priority, of which the students were trained by using Simodont virtual simulation system first and then conventional phantom-simulator system, the score of access and coronal cavity preparation was significantly higher than the score of training by using conventional phantom-simulator system only (14.30±1.77) (P<0.05). In the group of phantom-simulator priority, of which the students were trained by using conventional phantom-simulator system first and then Simodont virtual simulation system, the score of access and coronal cavity preparation was significantly higher than the score of training by using Simodont virtual simulation system only (14.10±1.45) (P<0.05). Moreover, in the group of virtual simulation priority, the score of training by using conventional phantom-simulator system after using Simodont virtual simulation system was significantly higher than that of training by using Simodont virtual simulation system only (P<0.05). The results of the questionnaire showed that the students fully agreed that "the Simodont virtual simulation system has the characteristics of repeatability, multi-dimension and multiple practice, and provides me with more attention to details" [80% (16/20)], however "it needs to be improved and upgraded to be close to the conventiaonl phantom-simulator system" [90% (18/20)]. Conclusions: Compared with using the conventional phantom-simulator system only, the preclinical teaching effectiveness of access and coronal cavity preparation could be effectively improved by using Simodont virtual simulation system combined with the phantom-simulator training system and might influenced by the training sequence.

Abstract
Background Information on the prevalence and resistance spectrum of nontuberculous mycobacteria (NTM) in China is mainly based on regional or local data. To estimate the proportion of NTM cases in China, a national survey of NTM pulmonary disease was carried out based on acid-fast positive sputum samples collected in 2013. Methods Sputum samples collected from enrolled presumptive cases in 72 nationwide tuberculosis surveillance sites from the 31 provinces in the mainland of China were cultured using L-J medium at the National tuberculosis reference laboratory (NTRL). MALDI-TOF MS identified the species of re-cultured strains, and minimal inhibitory concentrations (MICs) were determined to evaluate the drug susceptibility of NTM isolates. Data analysis used statistical software SPSS version 22.0 for Windows statistical package. Results Of 4917 mycobacterial isolates cultured, 6.4% [317/4917, 95% confidence interval (CI) 5.8%–7.2%] were confirmed as NTM, among which 7.7% (287/3709, 95% CI 6.9%–8.6%) were from the southern region. In inland and coastal China, 87.7% (95% CI 78.7%–93.2%) and 50.0% (95% CI 43.7%–56.3%) of isolates, respectively, were slow-growing mycobacteria (SGM), with the remaining rapid growing mycobacteria (RGM). A total of 29 species were detected, Mycobacterium abscessus had higher clarithromycin-inducible resistance rates than M. massiliense (65.67% vs 2.22%). M. kansasii presented lower resistance rates in linezolid and moxifloxacin than M. avium-intracellulare complex (3.23% vs 66.67%, 0 vs 47.22%) and other SGM (3.23% vs 38%, 0 vs 26%). Conclusions More NTM pulmonary disease was observed in the south and coastal China (P < 0.01). SGM was widely distributed, and more RGM are present in southern and coastal China (P < 0.01). The antimicrobial resistance spectrum of different NTM species was significantly different and accurate species identification would be facilitated to NTM pulmonary disease treatment.![]()

Abstract
Objective: To investigate the effect of body mass index (BMI) on clinical pregnancy and neonatal outcomes in patients with polycystic ovary syndrome (PCOS) during frozen-thawed embryo transfer. Methods: A total of 650 patients with PCOS who received routine in vitro fertilization or intracytoplasmic sperm injection treatment for frozen-thawed embryo transfer from June 2014 to June 2019 in Tianjin Central Hospital of Gynecology Obstetrics were retrospectively analyzed. According to BMI, PCOS patients were divided into group A (18.5≤BMI<23 kg/m2, n=253), group B (23≤BMI<25 kg/m2, n=167), and group C (BMI≥25 kg/m2, n=230). The general information, clinical pregnancy outcomes, pregnancy complications, the incidence of macrosomia and low-birth-weight infants were compared in the three groups, and the influencing factors of neonatal birth weight were analyzed. Results: The embryo implantation rate, clinical pregnancy rate, and ongoing pregnancy rate all showed downward trend with the increase of BMI, but the differences were not statistically significant (all P>0.05). The live birth rate in group C [47.0% (108/230)] was significantly lower than those in groups A and B, with statistical significance (χ²=7.43, P=0.024). The late miscarriage rate was higher in group C [9.4% (13/139)] than in groups A and B (χ²=7.66, P=0.022). The birth rates of macrosomia in groups B [22.2% (16/72)] and group C [21.1% (16/76)] were significantly higher than that in group A, and the difference was statistically significant (χ²=14.15, P=0.001). There was no statistically significant difference in the incidence of gestational diabetes between the three groups (χ²=3.81, P=0.149). The incidence of hypertension disorders complicating pregnancy increased with the increase of BMI, and the difference was not statistically significant (P>0.05). Regression analysis showed that macrosomia was significantly associated with maternal pre-pregnancy BMI and gestational weeks, and the risk of macrosomia increased by 15% (95%CI: 3%-28%) for every increase in maternal BMI. Conclusions: The embryo implantation rate, clinical pregnancy rate, and ongoing pregnancy rate of PCOS patients in frozen-thawed embryo transfer cycles show downward trend with the increase of BMI. Obese patients with PCOS have a significant increase in late miscarriage rate and a significant decrease in live birth rate. The incidence of hypertension disorders complicating pregnancy in PCOS patients in the obese group has an increasing trend, and the birth rate of macrosomia has increased significantly. Therefore, it is recommended that obese women with PCOS lose weight scientifically before pregnancy to improve pregnancy and neonatal outcomes.

Abstract
The importance of gut microbes to human health has gradually attracted attention. With the use of animal models, it has been revealed that maternal microbes during pregnancy could influence their children's health outcomes through shaping their microbial composition and regulating the development of their metabolic and immune system. However, the physiological mechanism of the human body is more complex and is affected by the interaction of multiple factors. The research results obtained from animal models are often inconsistent with human studies. At present, the influence of maternal intestinal microbes during pregnancy on the microbial colonization in their offspring and on a series of children's health outcomes is still unclear. Establishing a sub-cohort to detect the microbiome of the women across pregnancy and of their offspring, and further to integrate with variety of environmental and behavioral exposures can better provide reliable support for the research on the mechanism of children's health and diseases. This paper briefly introduces the research objectives, content, progress, strength and limitations of the sub-cohort study.

Abstract
Objective: To explore the relationship between the health literacy of employees and smoking, drinking, diet and exercise, and provide scientific basis for health education and targeted intervention. Methods: From February to July 2019, a cluster random sampling method was adopted to select enterprise employees in Shihezi City to conduct a questionnaire survey. Self-made questionnaires and "National Resident Health Literacy Monitoring Questionnaire" were used to assess the social demographics, health literacy, and Health-related behaviors were investigated, and 1053 valid questionnaires were collected. Logistic regression model was used to analyze the relationship between health literacy and the three dimensions with smoking, drinking, diet and exercise. Results: Total score of health literacy of enterprise employees is (42.06±11.03) points and the employee health literacy rate of Shihezi City in 2019 is 19.47%. Univariate analysis showed that non-smokers had higher health literacy and three-dimensional health literacy availability than smokers (P<0.01) ; fewer drinkers had higher health literacy availability than overdrinkers (P<0.05) ; balanced diet health literacy availability The health literacy availability rates in the three dimensions were higher than those in the unbalanced diet (P<0.01) . In the logistic regression analysis, healthy lifestyle and behavioral literacy were independently related to smoking behavior (OR=1.571, P<0.05) ; the presence of health literacy and the three dimensions of health literacy were not statistically related to alcohol consumption (P>0.05) ; there is a statistical correlation between health literacy, healthy lifestyles, behaviors, and health skills and regular exercise among employees (OR=1.829、2.503、1.395, P<0.05) ; employees with health literacy and three dimensions of health literacy are more likely to have a balanced diet (P<0.01) . Conclusion: There is a correlation between the health literacy of enterprise employees and diet and exercise. The improvement of health literacy level is an important way to interfere with unhealthy behaviors.

Abstract
Sofosbuvir has ushered in a new era of hepatitis C treatment with its strong inhibition on the replication of hepatitis C virus, favorable safety profile and less interactions with other drugs. Sofosbuvir-based regimens have been included as the first-line therapies for the treatment of adults with chronic hepatitis C (CHC) in international guidelines. Available clinical trial data show that sofosbuvir with ribavirin and ledipasvir/sofosbuvir are highly efficacious and safe in CHC patients aged 3-17 years old; therefore, they can meet the unmet medical needs of adolescents and children with CHC in China. Furthermore, the pan-genotypic sofosbuvir/velpatasvir is being investigated in adolescents and children with CHC, which is expected to make the treatment in such patients more convenient upon approval.

Abstract
Objective: To analysis the income and expenditure of HIV-positive pregnant women and the catastrophic health expenditure of their households in high AIDS endemic areas in Liangshan prefecture. Methods: From December 2018 to January 2019, a total of 250 pregnant women were recruited from 2 of 17 counties in Liangshan Prefecture, including 133 HIV-positive pregnant women and 117 HIV-negative pregnant women. The data, including basic information of pregnant women, basic information of the family, annual family income in 2017, annual family health expenditure in 2017, and maternal and child-related expenditure in 2017, were collected for analyzing the incidence of catastrophic health expenditure in the family. Results: The average annual income and average annual health expenditure of HIV-positive pregnant women households were 7 000 CNY and 2 000 CNY, while those of HIV-negative pregnant women households were 10 000 CNY and 3 000 CNY, respectively. Based on the criteria of 15%, 25% and 40%, the incidence of catastrophic health expenditure of HIV-positive pregnant households was 39.10%, 33.83% and 27.82%, with average differences of 34.84%, 31.17% and 26.65%, respectively, while that of HIV-negative pregnant women households was 38.46%, 33.33% and 23.93%, with average differences of 31.68%, 28.35% and 24.22%, respectively. Conclusion: The incidence of catastrophic health expenditure of pregnant households in high AIDS endemic areas in Liangshan prefecture is high. The incidence of HIV-positive families is slightly higher than that of HIV-negative families. We suggest that medical insurance compensation in Liangshan prefecture should be improved to reduce the impact of catastrophic health expenditure.

Abstract
Objective: To explore the clinicopathological characteristics and prognosis of patients with ovarian metastases from colorectal cancer. Methods: A total of 122 female patients with ovarian metastases from colorectal cancer underwent treatment in Cancer Hospital, Chinese Academy of Medical Sciences between 2010 and 2015 were recruited. The clinicopathological features, treatment details and survival data of these patients were retrospectively analyzed. Kaplan-Maier method was used for survival analysis, log rank test and Cox proportional hazards model were used for prognostic factor analysis. Results: The median overall survival (OS) was 19.7 months. The 1-year, 3-years and 5-years OS rates were 72.1%, 24.7% and 9.9%, respectively. A total of 99 (81.1%) patients underwent oophorectomy. The median OS of patients who underwent oophorectomy was 21.9 months, significantly longer than 10.3 months of patients without oophorectomy (P<0.01). Ovary as the only site of metastasis, primary tumor resection, and oophorectomy were associated with improved survival (all P<0.01). Primary tumor resection and oophorectomy were independent prognostic factors for OS (both P<0.01). Conclusion: Patients with ovarian metastases from colorectal cancer might acquire a survival benefit from surgical resection of the primary tumor and ovaries.

Abstract
Surgical resection remains the only curative therapy for colorectal adenocarcinoma and liver metastasis. Synchronous robotic resection for colorectal liver metastasis (CRLM) offers the advantage of avoiding double surgical stress, while providing the benefits of small incision, quicker recovery, shorter hospital stay and faster postoperative adjuvant therapy. Compared with the laparoscopic approach, robotic approach is mostly suitable for rectal cancer liver metastasis, which is associated with low conversion rate, good nerve protection, high success rate for major hepatectomy and resection of difficult segments. Appropriately selected patients, multidisciplinary cooperation and skillful robotic surgeons are the key to success. Current data have demonstrated the feasibility and safety of synchronous robotic resection for CRLM. With the coming randomized controlled trial data and evolution of robotic surgical system, the future of synchronous robotic resection for colorectal liver metastasis is promising.

Abstract
The fabrication process of restorations made by chairside computer aided design/computer aided manufacturing (CAD/CAM) is different from the conventional fabrication techniques. Chairside CAD/CAM system with digital intraoral scanning and in-practice milling device allows for a quick manufacturing of restorations. However, many factors involved in the clinical and CAD/CAM workflow may affect the clinical outcomes, especially the marginal adaptation of the restorations. This commentary summarizes the factors affecting the marginal adaptation of CAD/CAM restorations and recommends the solutions to achieve improved clinical outcomes.

Abstract
Non-small cell lung cancer (NSCLC) accounts for about 85% of all lung cancer cases. MicroRNAs (miRNAs/miRs) have been reported to play significant roles in the progression of human tumors, however, the expression and biological role of miR-23b in NSCLC remains elusive. Underexpression of miR-23b was detected in NSCLC tissues in comparison with the matched para-carcinoma tissues. The clinical value of miR-23b was analyzed, and the findings showed that miR-23b expression was negatively correlated with poor overall survival and malignant clinicopathologic characteristics of NSCLC patients. Furthermore, functional assays demonstrated that overexpression of miR-23b inhibited NSCLC cell viability, invasion and migration. Luciferase reporter assay and qRT-PCR revealed that RUNX2 was a functional target of miR-23b. The elevated expression of RUNX2 was positively correlated with overall survival of NSCLC patients. Additionally, Western blot analysis indicated that EMT and Wnt/β-catenin pathways were blocked by the upregulation of miR-23b. Taken together, these data demonstrated that dysregulation of miR-23b/RUNX2 signal may be a novel therapeutic target for the treatment of NSCLC.

Abstract
BACKGROUND Dorper sheep is an ideal breed for improvement, with higher meat production and increased adaptability. Artificial insemination is an efficient technique for Dorper genetic improvement and reproduction management. However, there is no uniform diluent for Dorper semen dilution. OBJECTIVE To compare the effects of vitamin B12 (VB12) and skimmed milk diluents on sperm motility at different ratios and time points, and the effects on conception rate. MATERIALS AND METHODS We detected the effect of diluents on sperm density, deformity, motility and conception rate of Dorper sheep. RESULTS We found the optimal dilution ratio of skimmed milk is 1:3. Compared to VB12, skimmed milk at 1:3 ratio prolonged semen storage time (48 h vs. 18 h, storage at a low temperature of 4°C) and increased the survival index of sperm (44.7 ± 2.8 vs. 18.5 ± 0.6, P<0.01). CONCLUSION Skimmed milk is more effective, nutritious and convenient than vitamin B12, representing a more advantageous diluent.

Abstract
OBJECTIVE To investigate the spatio-temporal distribution characteristics of Oncomelania hupensis snail habitats in three cities of Suzhou, Wuxi and Changzhou along the Taihu Lake region, so as to provide technical supports for establishing a sensitive and highly effective surveillance and forecast system for schistosomiasis. METHODS Snail distribution data were collected from Suzhou, Wuxi and Changzhou cities from 1950 to 2018, and the changing trend for snail habitats were described over years. In addition, the clusters of snail habitats were detected using Kernel density analysis and SaTScan space-time scan analysis. RESULTS The number of snail habitats appeared a single-peak distribution in Suzhou, Wuxi and Changzhou cities from 1950 to 2018, which peaked in 1970 and then declined rapidly. There were 62.68% of snail habitats eliminated within 10 years after identification, of which 38.24% were eliminated at the year of identification. Kernel density analysis and SaTScan space-time scan analysis revealed that high-density clusters of snail habitats were mainly distributed in Kunshan City, Wuzhong District and Xiangcheng District from 1970 to 1980, and in Yixing City in 1990; since then, the clusters gradually shrank, and overall appeared a move from northeast to west of Taihu Lake. A total of 4 new clusters were detected after 1970, as revealed by space-time scanning of snail habitats. In current snail habitats, emerging snail habitats are mainly identified in Huqiu District (Dongzhu Town), Wuzhong District (Guangfu Town), Taicang City (Shaxi Town) and Jintan District, and re-emerging snail habitats are scattered in 7 districts. CONCLUSIONS The distribution of snail habitats are spatio-temporal aggregation in Suzhou, Wuxi and Changzhou cities. The monitoring and prediction of emerging and re-emerging snail habitats are the key points in the future.

Abstract
Objective: To investigate the risk factors of turning temporary stoma into permanent stoma in rectal cancer patients undergoing transabdominal anterior resection with temporary stoma. Methods: A case-control study was carried out. Data of rectal cancer patients who underwent transabdominal anterior resection with temporary stoma and completed follow-up in Department of General Surgery of Xiangya Hospital of Central South University from June 2008 to June 2018 were collected and analyzed. In this study, temporary stoma included defunctioning stoma (ostomy was made during operation) and salvage stoma (ostomy was made within one month after operation due to anastomotic leakage or severe complications). Cases of multiple intestinal tumors were excluded. A total of 308 rectal cancer patients were enrolled in the study, including 198 males and 110 females with a median age of 56 (48-65) years. Ninety-four patients received intraperitoneal chemotherapy during operation. Among 308 patients, upper rectal cancer was observed in 64 cases, middle rectal cancer in 89 cases and low rectal cancer in 155 cases. Twenty patients underwent transverse colostomy and 288 underwent ileostomy. Phone call following-up was conducted from August to September 2019 to investigate whether stoma was reversed, causes of reversal failure, and tumor relapsed or not in detail. Permanent stoma was defined as that the stoma was still not reversed by the latest follow-up. The univariate analysis was performed with chi-square test or Fisher's exact test, and variables with P value < 0.10 were included in the non-conditional logistic regression model for multivariate analysis. Results: The median follow-up time was 54.3 (32.4-73.8) months. During follow-up, 8 cases had local recurrence and 37 cases had distant metastasis. Among the 308 patients with temporary ostomy, 247 (80.2%) patients had stomas reversed and the median interval time was 4.5 (3.5-6.1) months. The median interval time in 65 patients with salvage stoma was significantly longer that in 182 patients with defunctioning stoma [5.5 (4.3-7.5) vs. 4.2 (3.4-5.5) months; Z=-4.387, P<0.001]. The temporary ostomy was confirmed to become permanent stoma in 61 patients (19.8%), including 45 cases of defunctioning stoma and 16 cases of salvage stoma. Univariate analysis showed that preoperative anemia, intraperitoneal chemotherapy during operation, middle rectal cancer, transverse colostomy, pathological stage, postoperative local recurrence and distant metastasis were associated with permanent stoma (all P<0.10). Multivariate analysis revealed that the intraperitoneal chemotherapy during operation (OR=1.961, 95% CI: 1.029-3.738, P=0.041), middle rectal cancer (OR=2.401, 95% CI: 1.195-4.826, P=0.014), transverse colostomy (OR=3.433, 95% CI: 1.234-9.553, P=0.018), and distant metastasis (OR=8.282, 95% CI:3.820-17.954, P<0.001) were independent risk factors of permanent stoma. Conclusions: There is high risk of turning temporary stoma into permanent stoma among rectal cancer patients undergoing transabdominal anterior resection who receive intraperitoneal chemotherapy during operation, present as the middle rectal cancer, undergo transverse colostomy or develop distant metastasis. Surgeons need to evaluate and balance the risks and benefits thoroughly, and then inform the patients in order to avoid potential conflicts.

Abstract
Objective: To investigate the effect of gender on the efficacy of intra-aortic balloon pump(IABP) applied in patients with cardiogenic shock complicated by acute myocardial infarction(AMI). Methods: A total of 209 patients diagnosed as cardiogenic shock complicated by AMI admitted in Fuwai Hospital from June 2012 to May 2018 were enrolled in our study. We collected the data from medical records and investigated their clinical manifestation and laboratory examination and IABP support, as well as 28-day (from diagnosis of cardiogenic shock) mortality retrospectively. Kaplan-Meier survival analysis was used to compare the 28-day survival rates of patients of different genders/with or without IABP treatment. Adjustment for age, systolic blood pressure, ST segment elevation myocardial infarction, dual antiplatelet, coma, APACHEⅡ score and SAPSⅡ score, Cox regression analysis was used to detect the affect of IABP treatment on the risk of all-cause mortality in different crowd, and using Z test to evaluate the modification effect of gender on IABP treatment efficacy. Results: A total of 209 patients were included in this study, with 148 males (80 (54.05%) cases received IABP support) and 61 females (22 (36.06%) cases received IABP support). A total of 102 patients received IABP treatment. The 28-day survival rate of male patients was higher than that of females (39.2% (58/148) vs. 26.2% (16/61), Log-rank P=0.034). The 28-day survival rate of patients receiving IABP was significantly higher than that of non-IABP groups (46.1% (47/102) vs. 25.2% (27/107), Log-rank P=0.001 7). Among female patients, there was no statistically significant difference in 28-day survival rate between those who received IABP and those who did not receive IABP (P=0.889). While in male patients, the 28-day survival rate of those who received IABP was higher than that of those who did not receive IABP (51.2% (41/80) vs. 25.0% (17/68), P=0.001). The survival rate of male patients treated with IABP was higher than that of male patients who did not receive IABP, female patients who did not receive IABP and female patients who received IABP (all P<0.05). After multiple regression analysis and adjustment of confounding factors, it was found that IABP implantation can significantly reduce the 28-day mortality risk in male patients (HR=0.44, 95%CI 0.25-0.77 P=0.004). While it had no inpact on the death risk in female patients(P= 0.401). The impact of IABP implantation in patients of different genders was significantly different (Z=-2.32, P=0.020). Conclusion: In AMI patients complicating cardiogenic shock, there is a gender difference in the impact of IABP implantation on the 28-day mortality risk, and protective effects are seen only in men.

Abstract
Gram-negative bacterial infection causes an excessive inflammatory response and acute organ damage or dysfunction due to its outer membrane component, lipopolysaccharide (LPS). Protectin conjugates in tissue regeneration 1 (PCTR1), an endogenous lipid mediator, exerts fundamental anti-inflammation and pro-resolution during infection. In the present study, we examined the properties of PCTR1 on the systemic inflammatory response, organic morphological damage and dysfunction, and serum metabolic biomarkers in an LPS-induced acute inflammatory mouse model. The results show that PCTR1 reduced serum inflammatory factors and ameliorated morphological damage and dysfunction of the lung, liver, kidney, and ultimately improved the survival rate of LPS-induced acute inflammation in mice. In addition, metabolomics analysis and high performance liquid chromatography-mass spectrometry revealed that LPS-stimulated serum linoleic acid (LA), arachidonic acid (AA), and prostaglandin E2 (PGE2) levels were significantly altered by PCTR1. Moreover, PCTR1 upregulated LPS-inhibited fatty acid desaturase 1 (FADS1), fatty acid desaturase 2 (FADS2), and elongase of very long chain fatty acids 2 (ELOVL2) expression, and downregulated LPS-stimulated phospholipase A2 (PLA2) expression to increase the intrahepatic content of AA. However, these effects of PCTR1 were partially abrogated by a lipoxin A4 receptor (ALX) antagonist (BOC-2). In summary, via the activation of ALX, PCTR1 promotes the conversion of LA to AA through upregulation of FADS1, FADS2, and ELOVL2 expression, and inhibits the conversion of bound AA into free AA through downregulation of PLA2 expression to decrease the serum AA and PGE2 levels.

Abstract
Objective: To analyze the clinical characteristics, treatment and prognosis of patients with thrombotic thrombocytopenic purpura (TTP) . Methods: 83 patients with TTP from May 1998 to May 2019 were analyzed retrospectively. Results: Among the 83 patients, there were 27 males and 56 females, with a median age of 39 (10-68) years. 41 cases (49.4%) showed pentalogy syndrome and 79 cases (95.2%) showed triad syndrome. 78.0% (46/59) of the patients had a PLASMIC score of 6 or higher. TTP gene mutations was detected in 5 of 10 patients. The activity of von Willebrand factor-cleaving protease (ADAMTS13) , which was detected in 10 patients before plasma exchange (PEX) , was less than 10% in 9 patients. 83 patients were treated with PEX/plasma infusion and glucocorticoid, 35 of which were treated combined with rituximab and/or immunosuppressant. The median follow-up was 34 (1-167) months, the effective rate was 81.9%, the remission rate was 63.9%, the relapse rate was (35.7 ±7.1) %, and the 3-year overall survival (OS) rate was (78.6 ±4.6) %. The effective rate (72.9%vs 94.3%, P=0.019) and OS rate[ (63.8±7.5) %vs (94.3±3.9) %, χ(2)=8.450, P=0.004] in the group treated with PEX/PI and glucocorticoid alone were lower than those in the group treated combined with rituximab and/or immunosuppressant. COX multivariate analysis showed that age (HR=1.111, 95%CI 1.044-1.184, P=0.001) and alanine transaminase (ALT) /aspartate aminotransferase (AST) (HR=1.353, 95%CI 1.072-1.708, P=0.011) were independent risk factors for OS. Conclusion: Most patients with TTP have triad syndrome, accompanied by a decrease in ADAMTS13 activity. Plasma infusion and glucocorticoid combined with rituximab, immunosuppressive therapy could improve overall survival. The prognosis of patients with older age and high ALT/AST ratio is poor.

Abstract
Objective: To explore the correlation between prenatal clinical data with etiological diagnosis and neonatal outcome in isolated fetal ascites. Methods: Totally, 36 pregnancy cases diagnosed as isolated fetal ascites by ultrasound in Provincial Hospital Affiliated to Shandong University from June 22nd, 2016 to September 28th, 2018 were collected. Invasive prenatal diagnosis was performed by taking fetal cord blood, amniotic fluid, and fetal ascites respectively for cytogenetics, molecular genetics and biochemical examination and the impact of intrauterine therapeutic procedures on neonatal outcomes was evaluated as well. The correlation among prenatal examination, pathogeny and prognosis was analyzed by Fisher's exact test. Results: (1) The prognosis of isolated fetal ascites initially presenting ≥28 weeks was better than that before 28 weeks, survival rate of 1-year-old were 13/15 and 9/17,respectively, the difference was statistically significant (P<0.05). (2) The etiologic diagnosis rate of ascites before delivery was 31%(11/36), which increased to 53%(19/36) totally after birth. Characteristics of cases which were defined prenatally were as follows: 8 cases of digestive tract diseases showed ultrasonic abnormalities, including echogenic bowel, bowel dilatation and polyhydramnios; platelet level in umbilical cord blood of fetuses infected with cytomegalovirus were below 100 × 10(9)/L in 2 cases; 1 case of urinary system malformation showed megalocystis and hydronephrosis. Cases which were defined causes after birth included: 3 fetuses with chyloperitonium presented persistent fetal ascites; 3 cases of digestive-related causes were rectal duplication with infection, mesentery stenosis, and intestinal atresia; other causes included Pierre-Robin syndrome and Budd-Chiari syndrome. (3) The live birth rate was 72% (26/36) and survival rate of 1-year-old was 61% (22/36). And 9/10 of infants who underwent surgeries got good outcomes. Fetal ascites due to abdominal or pelvic factors turned well in 13/16 of cases. Conclusions: The pregnancy outcome of fetal isolated ascites depends mainly on primary causes. Gastrointestinal abnormality is one of the most common causes. Excluded intrauterine infection, chromosomal abnormality and abnormal systemic ultrasonic findings, fetus with reduced ascites as the pregnancy progresses will get good outcome.

Abstract
MiR-20a shows a significant role in the development of various human tumors. However, its specific biological function in non-small-cell lung cancer (NSCLC) is still not clear. qRT-PCR was applied for detecting miR-20a expression. The analysis of cell growth and apoptosis were performed by MTT, xenograft models, Western blot assays. Dual luciferase reporter, Western blotting and qRT-PCR were carried out to verify the potential target of miR-20a. In NSCLC tissues and cells, miR-20a was highly expressed and RUNX3 was lowly expressed. Moreover, up-regulation of miR-20a expression promoted NSCLC cell proliferation, invasion and migration, while low-expression of miR-20a showed the converse case on cell proliferation, invasion and migration. RUNX3 was verified as the direct target of miR-20a and it could overturn its biological function in NSCLC cells. Moreover, miR-20a negatively regulated RUNX3 expression. Mechanistically, increasing miR-20a expression inhibited RUNX3 expression and then activated the TGF-β signaling pathway. Taken together, our results demonstrated that re-expression of miR-20a promoted lung tumorigenesis by down-regulation of RUNX3 and facilitating the activation of TGF-β signaling pathway.

Abstract
BACKGROUND Cell-free DNA (cf-DNA)-based liquid biopsy is emerging as a revolutionary new method in individualized cancer treatment and prognosis monitoring, although detecting early-stage cancers using cf-DNA remains challenging, partially because of the undefined biological background of cf-DNA. MATERIALS AND METHODS We investigated somatic mutations in the cf-DNA of 259 cancer-free individuals with a median age of 47 years using an endogenous barcoding duplex method with an ultralow base error rate (2 × 10-7) and compared the variant allele frequencies (VAFs) of these mutations between the cf-DNA and the corresponding blood cell DNA. RESULTS Sixty percent (155/259) of the samples showed at least one nonsynonymous mutation on either of two similar target panels covering 508 and 559 cancer-related genes. For individuals older than 50 years of age, the positive rate increased to 76%. Most cf-DNA mutations were also present at similar VAFs in the paired blood cell DNA. The most frequently mutated genes were driver genes of hematologic malignancies, including DNMT3A, TET2, AXSL1, and JAK2. However, the other 58.4% (192/329) of the mutations were likely 'passenger mutations' of clonal hematopoiesis, including mutations in NOTCH2, FAT3, EXT2, ERBB4, and ARID2, which are driver genes of solid tumors. CONCLUSION Hematopoietic clone-derived mutations, including 'driver mutations' and 'passenger mutations', are prevalent in the cf-DNA of both healthy individuals and cancer patients and may be a potential source of false positives in the liquid biopsy. Our results also suggest the ineffectiveness for distinguishing clonal hematopoietic mutations of low VAF (≤0.1%) from tumor-derived mutations using conventional next-generation sequencing of blood cell DNA. However, an error correction model with an ultralow error rate and high coverage depth is required for blood cell DNA sequencing, which is difficult and costly to achieve with current technologies.

Abstract
Maresin Conjugates in Tissue Regeneration 1 (MCTR1) is a newly identified macrophage‐derived sulfido‐conjugated mediator that stimulates the resolution of inflammation. This study assessed the role of MCTR1 in alveolar fluid clearance (AFC) in a rat model of acute lung injury (ALI) induced by lipopolysaccharide (LPS). Rats were intravenously injected with MCTR1 at a dose of 200 ng/rat, 8 hours after administration of 14 mg/kg LPS. The level of AFC was then determined in live rats. Primary rat ATII (Alveolar Type II) epithelial cells were also treated with MCTR1 (100 nmol/L) in a culture medium containing LPS for 8 hours. MCTR1 treatment improved AFC (18.85 ± 2.07 vs 10.11 ± 1.08, P < .0001) and ameliorated ALI in rats. MCTR1 also significantly promoted AFC by up‐regulating epithelial sodium channel (ENaC) and Na+‐K+‐adenosine triphosphatase (Na, K‐ATPase) expressions in vivo. MCTR1 also activated Na, K‐ATPase and elevated phosphorylated‐Akt (P‐Akt) by up‐regulating the expression of phosphorylated Nedd4‐2 (P‐Nedd4‐2) in vivo and in vitro. However, BOC‐2 (ALX inhibitor), KH7 (cAMP inhibitor) and LY294002 (PI3K inhibitor) abrogated the improved AFC induced by MCTR1. Based on the findings of this study, MCTR1 may be a novel therapeutic approach to improve reabsorption of pulmonary oedema during ALI/acute respiratory distress syndrome (ARDS).

Abstract
OBJECTIVE To explore the spatio-temporal characteristics of Oncomelania hupensis snails along the Danyang section of the Beijing-Hangzhou Grand Canal and the Danyang-Jintan-Liyang Canal, so as to provide scientific evidence for the dynamic assessment of the risk of snail spread in this region. METHODS O. hupensis snail status was collected in the plain regions with waterway networks in the study area from 2012 to 2017. The spatio-temporal variations of snail distribution were investigated along the Danyang section of the Beijing-Hangzhou Grand Canal and the Danyang-Jintan-Liyang Canal using buffer zone analysis, spatial autocorrelation, hotspot analysis and standard deviational ellipse with the geographical information system (GIS) tools. RESULTS The number of snail habitats showed a tendency towards a rise in the study area from 2012 to 2017, and snail habitats were predominantly distributed in the 1 000 m long buffer zone of the Danyang-Jintan-Liyang Canal, notably along the Jiuqu River at the junction between the Beijing-Hangzhou Grand Canal and the Danyang-Jintan-Liyang Canal. The distribution of snail habitats appeared spatial autocorrelations in 2014, 2016 and 2017, and the hotspot areas were mainly identified at the junction between the Danyang-Jintan-Liyang Canal and the Beijing-Hangzhou Grand Canal. In addition, the overall distribution of snail habitats was located in the northeastern-southwestern part of the study aera, and gradually shifted to the southern and northern parts with the time. CONCLUSIONS The spatial distribution of O. hupensis snails is complex along the Danyang section of the Beijing-Hangzhou Grand Canal and the Danyang-Jintan-Liyang Canal, and there is a risk of snail spread from the upper reaches to the lower reaches, where snail control needs to be intensified.

Abstract
OBJECTIVE To understand the status of grass-roots schistosomiasis control professionals in Jiangsu Province, so as to provide scientific evidence for the rational resource allocation and the improvement of capability building. METHODS A cross-sectional survey was conducted by telephone interview and e-mail among city- and county-level disease prevention and control institutions that undertook schistosomiasis control activities in Jiangsu Province, and the age, educational background, major, duration of working, professional title and professional capability were descriptively analyzed. RESULTS There were totally 274 fulltime schistosomiasis control professionals working at grass-roots institutions in Jiangsu Province, with a mean age of (43.19 ± 9.47) years. The least professionals were below 30 years of age (12.77%, 35/274), and the most professionals were aged from 41 to 50 years (36.86%, 101/274). Among the 274 professionals, 43.07% (118/274) had duration of working of less than 10 years, 62.04% (170/274) had a bachelor degree, and 40.88% (112/274) had the medium-level professional title. CONCLUSIONS A schistosomiasis control team with a relatively high academic degree and professional title has been built at the grassroot level in Jiangsu Province. However, capability building remains to be improved through the participation of more young professionals and professional training with adaptation to local conditions.

[PMID: 32063483 DOI: 10.1016/j.diii.2020.01.014] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2019] [Revised: 01/18/2020] [Accepted: 01/22/2020] [Indexed: 12/20/2022]
Abstract
PURPOSE To compare the performance of biparametric magnetic resonance imaging (bpMRI) to that of multiparametric MRI (mpMRI) in combination with prostate-specific antigen density (PSAD) in detecting clinically significant prostate cancer (csPCa) in patients with PSA serum levels of 4∼10ng/mL. MATERIALS AND METHODS A total of 123 men (mean age, 66.3±8.9 [SD]; range: 42-83 years) with PSA serum levels of 4∼10ng/mL with suspected csPCa were included. All patients underwent mpMRI at 3 Tesla and transrectal ultrasound-guided prostate biopsy in their clinical workup and were followed-up for >1 year when no csPCa was found at initial biopsy. The mpMRI images were reinterpreted according to the Prostate Imaging Reporting and Data System (PI-RADS, v2.1) twice in two different sessions using either mpMRI sequences or bpMRI sequences. The patients were divided into 2 groups according to whether csPCa was detected. The PI-RADS (mpMRI or bpMRI) categories and PSAD were used in combination to detect csPCa. Receiver operating characteristic (ROC) curve and decision curve analyses were performed to compare the efficacy of the different models (mpMRI, bpMRI, PSAD, mpMRI+PSAD and bpMRI+PSAD). RESULTS Thirty-seven patients (30.1%, 37/123) had csPCa. ROC analysis showed that bpMRI (AUC=0.884 [95% confidence interval (CI): 0.814-0.935]) outperformed mpMRI (AUC=0.867 [95% CI: 0.794-0.921]) (P=0.035) and that bpMRI and mpMRI performed better than PSAD (0.682 [95% CI: 0.592-0.763]) in detecting csPCa; bpMRI+PSAD (AUC=0.907 [95% CI: 0.841-0.952]) performed similarly to mpMRI+PSAD (AUC=0.896 [95% CI: 0.828-0.944]) (P=0.151) and bpMRI (P=0.224). The sensitivity and specificity were 81.1% (95% CI: 64.8-92.0%) and 88.4% (95% CI: 79.7-94.3%), respectively for bpMRI, and 83.8% (95% CI: 68.0-93.8%) and 80.2% (95% CI: 70.2-88.0%), respectively for mpMRI (P>0.999 for sensitivity and P=0.016 for specificity). Among the 5 decision models, the decision curve analysis showed that all models (except for PSAD) achieved a high net benefit. CONCLUSION In patients with PSA serum levels of 4∼10ng/mL, bpMRI and bpMRI combined with PSAD achieve better performance than mpMRI in detecting csPCa; bpMRI has a higher specificity than mpMRI, which could decrease unnecessary biopsy, and may serve as a potential alternative to mpMRI to optimize clinical workup.

Abstract
Endothelial glycocalyx degradation, critical for increased pulmonary vascular permeability, is thought to facilitate the development of sepsis into the multiple organ failure. Maresin conjugates in tissue regeneration 1 (MCTR1), a macrophage-derived lipid mediator, which exhibits potentially beneficial effects via the regulation of bacterial phagocytosis, promotion of inflammation resolution, and regeneration of tissue. In this study, we show that MCTR1 (100 ng/mouse) enhances the survival of mice with lipopolysaccharide (LPS)-induced (15 mg/kg) sepsis. MCTR1 alleviates LPS (10 mg/kg)-induced lung dysfunction and lung tissue inflammatory response by decreasing inflammatory cytokines (tumor necrosis factor-α, interleukin-1β [IL-1β], and IL-6) expression in serum and reducing the serum levels of heparan sulfate (HS) and syndecan-1. In human umbilical vein endothelial cells (HUVECs) experiments, MCTR1 (100 nM) was added to the culture medium with LPS for 6 hr. MCTR1 treatment markedly inhibited HS degradation by downregulating heparanase (HPA) protein expression in vivo and in vitro. Further analyses indicated that MCTR1 upregulates sirtuin 1 (SIRT1) expression and decreases NF-κB p65 phosphorylation. In the presence of BOC-2 or EX527, the above effects of MCTR1 were abolished. These results suggest that MCTR1 protects against LPS-induced sepsis in mice by attenuating pulmonary endothelial glycocalyx injury via the ALX/SIRT1/NF-κB/HPA pathway.

Abstract
In recent years, with the improvement of high-intensity focused ultrasound technology, ultrasound cycloplasty has once again gained clinical recognition, becoming one of the non-invasive procedures for glaucoma treatment. Although high-level evidence is still lacking so far, the existing literature has shown that ultrasound cycloplasty can effectively and safely decreases the intraocular pressure in glaucoma by reducing the formation of aqueous humor and increasing the drainage of aqueous humor through the uveoscleral pathway. This article focuses on the efficacy and safety of ultrasound cycloplasty in the treatment of glaucoma, reviews the existing literature, and summarizes the information on the development of equipment, treatment mechanisms, surgical procedures, effectiveness of intraocular pressure reduction, and post-operative complications, with the purpose to provide reference for clinical research and application.

Abstract
Objective: To investigate the feasibility of echocardiography-guided closed-chest repeated intraventricular blood sampling in mice, and to clarify the maximum blood volume that can be collected by this method, and whether the method can be used for long-term repeated blood collection in mice. Methods: Twenty-four male C57BL/6J mice (10-14 weeks old) were divided into the terminal experiment group (n=4, for investigating the maximum blood amount that could be sampled at one time), the repeated 0.5 ml blood collection group (n=10, sampling 0.5 ml whole blood each time, once every two days for consecutive 4 weeks), and the repeated 0.75 ml blood collection group (n=10, sampling 0.75 ml whole blood each time, once every two days for consecutive 4 weeks). High-frequency echocardiography was used to display the largest section of the left ventricle, guiding the insulin syringe needle through the thorax into the left ventricle for blood collection. In the repeated 0.5 ml blood collection group, echocardiography was used to detect the cardiac structure and function before blood collection, three minutes after blood collection, and one week after the last (the 14th) blood collection. Results: We successfully performed echocardiography-guided closed-chest intraventricular blood sampling, with an average operating time (88±19)s per mouse, and a maximum blood volume (1.43±0.11)ml per mouse. In the repeated 0.5 ml blood collection group, heart rate, left ventricular ejection fraction, left ventricular fractional shortening, left ventricular end-diastolic dimension and left ventricular posterior wall end-diastolic thickness remained uncganged before the first blood collection and after 4 weeks of repeated blood collection (all P>0.05). No death in the repeated 0.5 ml blood collection group. However, in the 0.75 ml blood collection group, two mice died before the end point. Conclusions: The echocardiography-guided closed-chest intraventricular blood sampling is a safe, minimally invasive, convenient and efficient method, and can be used repeatedly for long-term blood collection in mice.

Abstract
OBJECTIVES We explored the associations between depressive symptoms and supplemental calcium and vitamin D intake in older adults. DESIGN This was a prospective cohort study. PARTICIPANTS 8,527 older adults aged ≥60 years from Zhejiang Major Public Health Surveillance Program (ZPHS) without depressive symptoms at baseline survey. MEASUREMENTS Participants were divided into non-supplementation, calcium (Ca), vitamin D, and calcium plus vitamin D (CaD) groups based on their supplemental intake during the past year. Depressive symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9). Binary logistic regression analyses were performed to examine the association between depressive symptoms and supplemental intake. RESULTS When compared to the non-supplementation group, the Ca group exhibited a significant odds ratio (OR) of 0.731 (95% CI: 0.552-0.967, P=0.028). After adjusting for age, sex, and Ca food sources, the OR was even smaller for the CaD group (OR: 0.326; 95% CI: 0.119-0.889, P=0.029). Additionally, our results indicated that taking Ca supplements ≥4 days/week yielded a significant OR of 0.690 (95% CI: 0.492-0.968) after full adjustment. Taking CaD supplements ≥4 days/week yielded a significant OR of 0.282 (95% CI: 0.089-0.898) after adjusting for age, sex, and Ca food sources. CONCLUSIONS Supplemental intake of Ca or CaD ≥4 days/week can decrease the risk of depressive symptoms in older adults, although CaD supplements may be more effective.

Abstract
Objective: To examine the association of pre-pregnancy body mass and weight gain during pregnancy with macrosomia. Methods: From January 2015 to December 2015, a total of 20 477 pregnant women were recruited by probabilistic proportional scale sampling with simple randomization in Sichuan, Yunnan and Guizhou Provinces. Basic information of pregnant women, weight gain during pregnancy and weight of newborn were collected. A multiple logistic regression model was used to assess the association between the pre-pregnancy body mass and gestational weight gain indicators with macrosomia. Results: 20 321 mother-infant were included in the final analysis. 20 321 pregnant women were (30.09±4.10) years old and delivered at (39.20±1.29) weeks, among which 12 341 (60.73%) cases were cesarean delivery. The birth weight of 20 321 infants were (3 292.26±431.67) grams, and 970 (4.77%) were macrosomia. The multiple logistic regression model showed that after adjusting for the age of women, compared to the normal weight group in the pre-pregnancy, the overweight and obesity group elevated the risk of macrosomia, with OR (95%CI) about 1.99 (95%CI: 1.69-2.35) and 4.05 (95%CI: 3.05-5.39), respectively. After adjusting for the age, the pre-pregnancy BMI, delivery weeks, delivery mode and infant's gender, compared to the weight-gain appropriate group, higher weight gain rate in the mid-pregnancy and excessive total gestational weight gain elevated the risk of macrosomia, with OR (95%CI) about 1.99 (95%CI: 1.66-2.39) and 1.80 (95%CI: 1.55-2.08), respectively. Conclusion: The overweight before pregnancy, obesity before pregnancy, the rate of weight gain in the second trimester and the high total weight gain during pregnancy could increase the risk of macrosomia.

Abstract
OBJECTIVE To analyze and investigate the changing trend of the endemic situation of schistosomiasis in national surveillance sites of Jiangsu Province from 2011 to 2018, so as to provide scientific evidence for formulating strategies for schistosomiasis control. METHODS From 2011 to 2014, the national schistosomiasis surveillance sites were set in seven schistosomiasis endemic counties (cities, districts) across Jiangsu Province as according to the National Schistosomiasis Surveillance Scheme (2011 version), and from 2015 to 2018, the national surveillance sites were assigned in all 64 counties (cities, districts) endemic for schistosomiasis in Jiangsu Province according to the National Schistosomiasis Surveillance Scheme (2014 version). Schistosoma japonicum infections in local populations, mobile populations and livestock, and snail status were monitored in the national schistosomiasis surveillance sites of Jiangsu Province from 2011 to 2018, and the monitoring data were statistically analyzed. RESULTS The sero-prevalence of S. japonicum infections was 1.50% to 4.61% among local populations in the national schistosomiasis surveillance sites of Jiangsu Province from 2011 to 2018, and a higher sero-prevalence was seen in men than in women, with the sero-positives predominantly detected in local populations at ages of over 50 years. The positive rate of stool examinations was 0 to 0.14% among sero-positive local populations in the national schistosomiasis surveillance sites of Jiangsu Province from 2011 to 2018, and no acute case was found in local populations during the study period. The sero-prevalence of S. japonicum infections was 0.46% to 15.97% among mobile populations in the national schistosomiasis surveillance sites of Jiangsu Province from 2011 to 2018, and no egg-positives were identified. A total of 1 453 livestock were tested in the national schistosomiasis surveillance sites of Jiangsu Province from 2011 to 2018, and no S. japonicum infections were detected. During the period from 2011 through 2018, snail survey was conducted in an area of 216 million m2 in the national schistosomiasis surveillance sites of Jiangsu Province, and 1 291.01 hm2 snail habitats were identified, with snail densities ranging from 0.01 to 0.47 snails/0.1 m2; however, no S. japonicum infections were identified in snails. CONCLUSIONS The overall endemic situation of schistosomiasis appears a tendency towards a decline in Jiangsu Province, and S. japonicum infection remains at a low level in both humans and livestock. No S. japonicum infection has been identified in local populations in Jiangsu Province since 2012. In the future, monitoring and management of imported sources of S. japonicum infections should be intensified in Jiangsu Province, and the capability building of passive surveillance of schistosomiasis should be improved in sentinel hospitals in national schistosomiasis surveillance sites of Jiangsu Province. In addition, the examination of schistosomiasis should be strengthened in mobile populations in Jiangsu Province, a sensitive and effective surveillance-response system for schistosomiasis is urgently needed.

Abstract
Objective: To investigate the influence of five-in-one management mode(standardized asthma treatment, asthma diary, peak expiratory flow (PEF) monitoring, reasonable diet and physical exercise) on disease prevention and control of school children with asthma. Methods: From April to October 2018, 70 children with asthma in clinical remission were selected from Affiliated Hospital of Qingdao University using randomized controlled study design. These children were randomly divided into study group and control group, with 35 cases in each group. In the study group, 5 cases were lost to follow-up, and 30 cases were actually enrolled. In the control group, 6 cases were lost to follow-up, and 29 cases were actually enrolled. Children in the control group received routine medication and regular outpatient consultation, and children in the study group received the five-in-one asthma management model. In the first time of seeing a doctor, after 3 months and 6 months of follow-up, asthma control test score, medication compliance index score and lung function index (forced expiratory volume in 1 second (FEV1), PEF were evaluated respectively.Parental satisfaction, asthma acute episodes, weight, height and biochemical index were recorded during the 6 months of follow-up. Pulmonary function index, asthma control score and body mass index of overweight children with asthma were compared with t-test, medication compliance was compared with chi-square test, and the rank sum test was used for the comparison of the number of emergency visits of asthma attacks and parents' satisfaction. Results: A total of 59 children with asthma were included, among them 30 were in the study group (8.1±1.5) years old and 29 in the control group (9.2±1.1) years old. After 3 months of follow-up, FEV1, PEF, asthma control score in the study group were (86.3±1.5)%, (83.3±2.4)%, (24.7±2.6) points respectively; and in the control group, FEV1, PEF, asthma control score were (84.4±2.5)%, (82.2±1.9)%, (21.1±1.3) points respectively. The indicators in the study group were higher than those in the control group (t=3.62, 1.97, 6.64, P<0.05). After 6 months of follow-up, FEV1, PEF, asthma control score in the study group were (88.4±2.3)%, (85.4±2.2)%, (26.8±1.8) points respectively; and in the control group, FEV1, PEF, asthma control score were (85.5±1.9)%, (83.2±1.7)%, (22.5±1.4) points respectively. The indicators in the study group were significantly higher than those in the control group (t=5.34, 4.24, 10.41, P<0.05). During the 6-month follow up, the number of emergency visits of asthma attacks in the study group and in the control group were 0.42(0.36, 0.51) and 0.92(0.72, 1.27) respectively. The indicator in the study group was significantly lower than that in the control group (Z=3.21, P<0.05). After 3 months of follow-up, the proportions of children with good compliance in the study group and control group were 67% (20/30) and 62% (18/29), the proportions of poor compliance were 27% (8/30) and 34% (10/29), the proportions of non-compliance were 7% (2/30) and 7% (2/29). There were no statistically significant differences (χ(2)=0.14, 0.43, 0.00, P=0.71, 0.51, 0.97). After 6 months of follow-up, the proportions of children with good compliance in the study group and control group were 87% (26/30) and 69% (20/29), the proportion of poor compliance were 10% (3/30) and 28% (8/29), the proportion of non-compliance were 3% (1/30) and 7% (2/29), There were no statistically significant differences (χ(2)=2.70, 3.00, 0.39, P=0.10, 0.08, 0.53). After 6 months of follow-up, the number of great satisfaction, satisfaction and dissatisfaction in the study group were 20, 10 and 0 respectively, the satisfaction rate was 100%, meanwhile those indicators in the control group were 4, 15 and 10 respectively, the satisfaction rate was 66%, The indicator in the study group was significantly higher than that in the control group (Z=4.60, P<0.05). Conclusions: The application of "five-in-one" asthma management model (standardized asthma treatment, asthma diary, PEF monitoring, reasonable diet and physical exercise) for school-age children with asthma can significantly improve lung function, as well as reduce the number of acute asthma attacks. It has a high parent satisfaction, therefore it should be recommended for clinical implementation.

Abstract
Objective: To examine the relative factors of transmural intestinal necrosis (TIN) during multidisciplinary stepwise management facilitating the decision making in patients with acute superior mesenteric vein thrombosis (ASMVT). Methods: Clinical data of patients with ASMVT admitted to Department of General Surgery, Jinling Hospital from January 2009 to June 2017 were reviewed retrospectively. There were 52 males and 37 females, aging (45.9 ± 12.6) years (range: 20 to 69 years). According to the postoperative pathological results and follow-up, the patients were divided into TIN group (n=31) and non-TIN group (n=58, including 18 cases of intestinal stricture). The related factors were compared between ASMVT patients with TIN and patients without TIN by univariate analysis using t test, U test and χ(2) test accordingly, and factors with statistically significance were subsequently submitted to binary Logistic regression analysis. The predictive value and cut-off point of factors were evaluated by receiver operator characteristic (ROC) curve and area under the curve. Results: In univariate analysis, smoking, hypertension, peritonitis, white blood cell count,haemoglobin, international normalized ratio, blood albumin, thrombosis of superior mesenteric branches vein, free intraperitoneal fluid, decrease of bowel wall enhancement and pneumatosis intestinalis were TIN risk factors (all P<0.05). According to the binary Logistic regression analysis, white blood cell count (OR=1.093, 95%CI: 1.010 to 1.182, P=0.027), thrombosis of the superior mesenteric branches vein (OR=11.519, 95%CI: 1.906 to 69.615, P=0.008), pneumatosis intestinalis (OR=11.140, 95%CI: 2.360 to 52.585, P=0.002) were independent relative factors of TIN in patients with AMI, and the area under the ROC curve of the above factors and predictive model was 0.759 (95%CI: 0.647 to 0.871), 0.745 (95%CI: 0.641 to 0.848), 0.737 (95%CI: 0.621 to 0.854), 0.909 (95%CI: 0.847 to 0.971), respectively. The cutoff value of white blood cell count was 18.1 × 10(9)/L. Conclusion: White blood cell levels, superior mesenteric vein branch thrombosis and pneumatosis intestinalis are independent predictors of TIN in ASMVT.

Abstract
Objective: To understand the early infant diagnosis (EID) test rate and associated factors in HIV-exposed children in China during 2015-2017. Methods: The follow-up information cards of 12 096 HIV-exposed children for 18 months after birth during 2015-2017 were collected from the Management Information System of China's Prevention of Mother-to-Child Transmission of HIV for a retrospective analysis. The EID test characteristics of HIV exposed children and associated factors were analyzed. Results: From 2015 to 2017, the EID test rate in HIV exposed children increased from 65.6% to 83.4% in China (trend χ(2) P<0.001). The EID test rate within 8 weeks after birth increased from 61.1% to 76.8% (trend χ(2) P<0.001), but the EID positive rate decreased from 8.7% to 3.4% (trend χ(2) P<0.001). The EID positive rate in fatal HIV-exposed children was 47.7%, 36.9% and 36.3% during 2015-2017, respectively, the differences were not significant. EID test rate was associated with ethnic group, living area, survival status and the year reaching 18-month-old of the children. Conclusions: The performance of EID test has been standardized step by step in China. The positive rate of EID test decreased gradually with year. However, the EID test rates in children who were from minority ethnic groups, lived in areas with lower prevalence of HIV infection and died within 18 months after birth were relatively low.

Abstract
Draf type Ⅱb/Ⅲ frontal sinus surgery has been widely used in clinical practice. They can obtain a wide operating space and sufficient drainage pathways. However, the mucosa around the frontal sinus ostium was removed during the surgery, resulting in bone exposure, and sinus ostium stenosis or atresia may occur after the operation. In recent years, rhinologists at home and abroad have applied various mucosal flaps to cover the exposed bone around the frontal sinus orifice after Draf Ⅱb/Ⅲ frontal sinus surgery, in order to reduce scar formation and bone hyperplasia along with the incidence of frontal sinus ostium stenosis or atresia after surgery. Satisfactory results have been achieved. The article reviews the application of mucosal flap technique in Draf Ⅱb/Ⅲ frontal sinus surgery, in order to promote the clinical research and technical development of this technique in China.

Abstract
OBJECTIVE To assess the total factor productivity (TFP) of schistosomiasis control programs in Jiangsu Province, so as to provide insights into sustainable schistosomiasis control. METHODS The data envelopment analysis-Malmquist index method was employed to analyze the human resources and financial investments in schistosomiasis control programs from health sectors in each schistosomiasis-endemic city of Jiangsu Province from 2005 to 2015, and assess the outputs of each schistosomiasis control project. RESULTS The overall productive efficiency of schistosomiasis control programs in Jiangsu Province showed an increasing tendency, and the mean fluctuation of annual TFP was 2.3%. The comprehensive technical efficiency, including pure efficiency and scale efficiency, appeared a steady increase with minor fluctuations, and the mean fluctuation of annual comprehensive technical efficiency was 3.8%. The growth rate of technical progress fluctuated greatly from 2005 to 2011, and showed a steady increase from 2012 to 2015, which became a major contributor to the growth of TFP. A higher growth rate of TFP was seen in Huai ' an and Changzhou cities, which showed a greater comprehensive technical efficiency, and a large fluctuation was observed in the growth rate of technical progress in Yancheng, Nanjing, Huai ' an and Yangzhou cities. CONCLUSIONS There is a continuous improvement in the technical level of schistosomiasis control programs in Jiangsu Province, and technical application and supervision and management capacity also show a steady increase. In addition, the application of new techniques and new strategies contributes greatly to TFP growth. In the future, the investment into new techniques and new strategies should be increased to ensure the sustainable schistosomiasis control in Jiangsu Province.

Abstract
Objective: To evaluate risk factors for visual field (VF) loss progression in primary open-angle glaucoma patients. Methods: A prospective nested case-control study. Patients were collected from the Wenzhou glaucoma progression study in the Eye Hospital of Wenzhou Medical University during March 2014 and April 2018. In this study, the eyes were divided into a progression group and a non-progression group using the glaucoma progression analysis methods to analyze the risk factors for glaucomatous VF loss progression. Axial length (AL) and central corneal thickness (CCT) were measured using the Lenstar LS900. The baseline, fluctuation (standard deviation), mean, maximum, minimum and range of intraocular pressure (IOP) during the follow-up period were determined based on IOP measured at each follow-up. The IOP measurements were included from the baseline to the last visit (for the non-progression group), or to the visit at which VF loss progression was determined (for the progression group). The independent sample t-test, Mann-Whitney U inspection and Cox proportional hazards models were used for statistical analysis. Results: A total of 140 patients (140 eyes) were enrolled, including 67 males and 73 females. There were 19.3% of the eyes (27 of 140 eyes) showing VF loss progression. The median time to the endpoint for progression was 24.0 (16.0, 40.0) months. The AL in the progression group and non-progression group were 23.58 (23.05, 24.24) mm and 23.91 (23.10, 24.91) mm (P=0.111). The CCT in the two groups were 531.0 (512.0, 565.0) μm and 535.0 (518.5, 552.0) μm, respectively (P=0.897). The baseline age in the progression group and non-progression group was 71.0 (68.0, 74.0) years and 68.0 (58.0, 72.0) years, respectively (Z=-2.872, P=0.004). The slope of visual field index in the two groups was -3.50 (-7.10, -1.80)%/year and 0.40 (-0.60, 1.40)%/year, respectively (Z=-6.823, P<0.01). The mean IOP during the follow-up was (16.2±2.7) mmHg (1 mmHg=0.133 kPa) in the progression group and (15.1±2.4) mmHg in the non-progression group (t=-2.215, P=0.028). The IOP fluctuation in the progression group and non-progression group was (2.6±1.3) mmHg and (2.0±0.7) mmHg, respectively (t=-2.175, P=0.038). In the multivariate model, older baseline age (HR=1.080; 95%CI:1.019-1.143), higher baseline IOP (HR=1.120; 95%CI:1.016-1.236), higher mean IOP (HR=1.145; 95%CI:1.001-1.309) and higher IOP fluctuation (HR=1.750; 95%CI:1.193-2.566) were all significantly predictive risk factors for glaucomatous VF loss progression. Longer AL (HR=0.725; 95%CI:0.532-0.988) was a protective factor against VF loss progression. However, CCT was found to be not associated with VF loss progression. Conclusion: Baseline age, baseline IOP, mean IOP, IOP fluctuation and shorter AL are found to be risk factors for glaucomatous VF loss progression among eyes with primary open-angle glaucoma in Wenzhou.

Abstract
Objective: To investigate the genetic characteristics and clinical outcomes of pediatric acute myeloid leukemia patients with NUP98-NSD1 fusion gene. Methods: A total of 80 pediatric AML patients were enrolled in this study, and bone marrow specimens were collected at initial diagnosis and relapse. NUP98-NSD1 was screened by fluorescence in situ hybridization (FISH) and PCR. Other laboratory test results and clinical outcomes were further analyzed for the NUP98-NSD1 positive cases. Results: A total of eight patients (10.0%) were positive for NUP98-NSD1, which were all fusions of NUP98 exon12 and NSD1 exon 6. There were two M2, three M4, and three M5 cases according to the French-American-British classification. Seven patients had karyotype results at the time of initial diagnosis, and none of them had complicated karyotype abnormalities. Among these patients, two cases had normal karyotype, three cases had trisomy 8, one case had trisomy 6, and two cases had anomalies involving 9q13 or 9q21. Additional karyotypic abnormalities and clonal evolutions were observed during disease progression or relapse, five cases had 9q13 or 9q32 abnormalities. Five cases (62.5%) were positive with FLT3-ITD mutation. Patients were treated with DAE/NAE/HAE/IA chemotherapy. Three cases did not achieve remission after several courses of chemotherapy, and five cases achieved remission but relapsed in 1 to 19 months. Five cases underwent salvage allogeneic hematopoietic stem cell transplantation (allo-HSCT). Among whom, four died in 40 days to 4 months after transplantation, and one survived 8.5 months till the last follow-up. Conclusions: NUP98-NSD1 is a recurrent genetic abnormality with significant clinical prognostic significance, and this group of disease has unique clinical and genetic characteristics. NUP98-NSD1 should be screened by FISH or PCR for children with AML who are newly diagnosed or refractory and relapsed to identify the high-risk genetic marker.

Abstract
"" was recorded in Liu Jie Zang Xiang Lun of Su Wen (《·》, On Six-Period and Visceral Manifestation of Plain Questions), and there has been 11 versions of interpretation on "Pi Ji ()" in last 400 years since Wu Kun of the Ming dynasty. "Pi Ji ()" appeared 3 times in Xuanquan Han slips, annotated as "Pi Ji ()" , denoting " (fatigue)" , a synonymous compound word. "Pi Ji ()" was seen on 9 occasions in Shi Ji (《》, The Historical Records) and Han Shu (《》, History of The Former Han) altogether, with the annotation of "Pi Kun (fatigue and tiredness)" by Yan Shigu. It is confirmed that the "Pi Ji ()" means " (fatigue)" and the "" can thus be interpreted as "Liver is the root of utmost exhaustion or fatigue" , with a combination of evidence from excavated texts and existing literature records supported by clinical and experimental data.

Abstract
Objective: To summarize the characteristics of abdominal-pelvic unplanned reoperation (URO) in a cancer hospital. Methods: Retrospectively descriptive cohort research was adopted. The classification of diseases was based on ICD-10, and surgical classification was based on ICD-9-CM-3. Medical record summary database from 2008 to 2018 in Beijing Cancer Hospital was collected, and all URO information of abdominal-pelvic surgery was retrieve. The time of URO, disease type, surgery type and cause were statistically analyzed. Distribution of main disease incidence and constituent ratio, and the application of major surgery and surgery type composition ratio were analyzed as well. Results: From 2008 to 2018, a total of 46854 cases underwent abdominal-pelvic surgery (including gastrointestinal, hepatic-biliary-pancreatic, gynecological, urological, or esophageal cancer surgery) and 713 patients received URO (1.52%), including 486 males and 227 females (2.14:1.00) with a mean age of (58.1±12.2) years. A total of 246 patients (34.50%) had comorbidity, and with comorbidity: without comorbidity was 1.13:1.00. The hospital stay was (44.5±43.0) days, and the total cost was (178000±112000) yuan. There were 22 deaths (3.09%). The median interval between URO and the first operation was 8 (0 to 131) days. The highest rate of URO was 2.45% (89/3629) in 2012, while the lowest was 0.95% (53/5596) in 2015. The top 3 major cancer types of URO included colorectal cancer (222 cases, 31.14%), gastric cancer (166 cases, 23.28%) and esophageal cancer (45 cases, 6.31%). The cancer types with the highest URO rate included pancreatic cancer (3.97%, 30/756), gastric cancer (1.81%, 166/9171) and colorectal cancer (1.80%, 222/12333). The top 3 surgical procedures resulting in URO were rectal resection (109 cases, 15.29%), total gastrectomy (79 cases, 11.08%), and total pancreatectomy (64 cases, 8.98%). Focusing on 497 URO cases from 2012 to 2018, 465 cases (93.56%) followed relatively difficult grade III and IV surgery, while only 32 cases (6.44%) followed grade I and II surgery. The top 5 main causes of URO were bleeding (225 cases, 31.56%), anastomotic leak (225 cases, 31.56%), infection (89 cases, 12.48%), intestinal obstruction (53 cases, 7.43%), and wound dehiscence (35 cases, 4.91%), adding up to a total of 87.94% of all URO. Conclusion: This study summarizes the epidemiology of abdominal - pelvic URO in our cancer institution, providing the solid baseline for future investigation of URO and the subsequent formulation of corresponding prevention and intervention measures.

Abstract
Objective: To investigate the value of acoustic parameters in the voice therapy for patients with unilateral vocal cord paralysis (UVCP). Methods: From May 2015 to April 2018, 51 patients with UVCP and 59 healthy controls in Department of Otorhinolaryngology Head and Neck Surgery, Tianjin First Central Hospital, were involved in this research retrospectively. The UVCP patients were diagnosed with stroboscopic laryngoscopy. The minimum glottal area (MGA) was calculated by KIPS software when the people were pronouncing/i:/. The fundamental frequency (F0), Jitter, Shimmer and NHR were detected by CSL4500 multiple acoustic voice analyzer. Results: MGA of UVCP patients was much higher than that of healthy control (male: 433.68±64.52 vs. 294.41±51.82, t=9.23, P=0.000; female: 498.80±73.42 vs. 302.03±76.54, t=13.21, P=0.000), which meaned vocal cord insufficiency.After voice therapy, MGA reduced significantly (male: 288.48±55.09, female: 258.22±57.17, t=24.41 and 31.22, P=0.000 vs. pre-therapy). MGA of untreated patients decreased in varying degrees. Compared with the voice therapy group, the MGA decreased in a significantly lower extent (24.25±22.91 vs. 188.31±54.37, t=8.97, P=0.000). The F0, Jitter, Shimmer and NHR raised significantly in UVCP patients group (P=0.000 vs. healthy control group), and they were reduced by voice therapy (all P<0.05). Each of the four acoustic parameters was relative with MGA, r=0.551, 0.867, 0.853 and 0.875 in turn, P=0.001, 0.000, 0.000, and 0.000. Conclusion: MGA and acoustic parameters can reflect the acoustic features of UVCP patients, which are useful tools in the UVCP assessment and voice therapy.
