Abstract
This study aimed to examine the impact of trivalent, divalent, or monovalent cations dissolving into water and being mixed with maize starch to influence its retrogradation, gelatinization, and gel characteristics. The result of the analysis using a differential scanning calorimeter showed that all cations raised the peak of gelatinization temperature of maize starch, especially Al3+ or Fe3+, while trivalent cations reduced the enthalpy. The result of the analysis using a rapid viscosity analyzer showed that trivalent cation caused lower trough viscosity, final viscosity, and pasting temperature but higher breakdown viscosity of maize starch than monovalent or divalent cations. Confocal laser scanning microscopy showed that the cation promoted the destruction of gelatinized maize starch granules, especially Zn2+, Fe3+, or Al3+. Additionally, trivalent Fe3+ or Al3+ caused higher gel strength of maize starch. Generally, the cation with higher valence changed more retrogradation, gelatinization, and gel characteristics of maize starch.

Abstract
MicroRNAs have been shown to potentially function in cerebral ischemia/reperfusion (IR) injury. This study aimed to examine the expression of microRNA-320 (miR-320) in cerebral IR injury and its involvement in cerebral mitochondrial function, oxidative stress, and inflammatory responses by targeting the HMGB1/NF-kappaB axis. Sprague-Dawley rats were subjected to middle cerebral artery occlusion to simulate cerebral IR injury. The cerebral expression of miR-320 was assessed using qRT-PCR. Neurological function, cerebral infarct volume, mitochondrial function, oxidative stress, and inflammatory cytokines were evaluated using relevant methods, including staining, fluorometry, and ELISA. HMGB1 expression was analyzed through Western blotting. The levels of miR-320, HMGB1, neurological deficits, and cerebral infarction were significantly higher after IR induction. Intracerebral overexpression of miR-320 resulted in substantial neurological deficits, increased infarct volume, elevated levels of 8-isoprostane, NF-kappaBp65, TNF-alpha, IL-1beta, ICAM-1, VCAM-1, and HMGB1 expression. It also promoted the loss of mitochondrial membrane potential and ROS levels while reducing MnSOD and GSH levels. Downregulation of miR-320 and inhibition of HMGB1 activity significantly reversed the outcomes of cerebral IR injury. MiR-320 plays a negative role in regulating cerebral inflammatory/oxidative reactions induced by IR injury by enhancing HMGB1 activity and modulating mitochondrial function.

Abstract
The objective of this study was to investigate the effects of monovalent, divalent and trivalent cations on the physicochemical properties of potato starch. Cations decreased the water absorption in potato starch granules to cause lower swelling power, especially 0.02-0.04 mmol/g Fe3+ or 0.01-0.04 mmol/g Al3+, but 0.01 mmol/g trivalent cation led more amylose dissolving into the water to cause higher solubility. High concentration of divalent or trivalent cations markedly decreased the viscosity in potato starch paste during further heating and cooling, resulting in the decreases of the trough and finial viscosity, especially 0.04 mmol/g Fe3+. Higher valence of cations decreased the gel strength in potato starch, especially 0.02-0.04 mmol/g Fe3+ or Al3+. Higher valence of cations decreased the starch gel binding with the water and caused lower water holding capacity. In general, a higher valence of cations caused more changes in the physicochemical characteristics of potato starch.

Abstract
OBJECTIVES The global prevalence of osteoporosis is rising, yet it is unclear whether people with osteoporosis have a higher risk of depression than those without osteoporosis. STUDY DESIGN A cross-sectional study. METHODS We used nationally representative data from the US National Health and Nutrition Examination Survey (NHANES) in 2005-2006, 2007-2008, 2009-2010, 2013-2014, and 2017-2020. The diagnosis of osteoporosis was based on the bone mineral density of the femoral neck measured by dual-energy X-ray absorptiometry. Depression was assessed by the Patient Health Questionnaire-9 (PHQ-9), with a score ≥5 as depressive symptoms and a score ≥10 as probable depression. We used logistic regression models to evaluate the association between osteoporosis and depressive symptoms and probable depression. RESULTS We included 11,603 adults (aged 50 years and older, 52.3% male) and observed 5.2% of them had osteoporosis. 31.9% of these osteoporotic people had depressive symptoms, and 10.0% had probable depression. Compared to participants without osteoporosis, those with osteoporosis were 1.73 times more likely to experience depressive symptoms (odds ratio [OR] = 1.73, 95% confidence interval [CI] 1.20-2.50) and 1.91 times more likely to experience probable depression (OR = 1.91, 95% CI 1.02-3.59), after adjusting for sex, age, race/ethnicity, education, marital status, family income, body mass index, smoking, physical activity, and alcohol abuse. Moderate-to-vigorous activities mediated the associations between osteoporosis and depression and depressive symptoms. CONCLUSIONS Osteoporosis is an independent risk factor for depression. This study highlights the need to evaluate the mental well-being of patients with osteoporosis in clinical and primary health care.

Abstract
PURPOSE/OBJECTIVE(S) We evaluated the safety and efficacy of hypofractionated radiotherapy (HFRT) combined with tyrosine kinase inhibitors (TKIs) in patients with pulmonary metastases after orthotopic liver transplantation (OLT) for hepatocellular carcinoma (HCC). MATERIALS/METHODS Twenty-five patients with lung metastases after OLT for HCC who underwent HFRT using helical tomotherapy concomitantly with TKIs (sorafenib or lenvatinib) were retrospectively. The primary endpoint was progression-free survival (PFS). The secondary endpoints were overall survival (OS), local control rate (LCR), objective response rate (ORR), and treatment-related side effects. RESULTS The median follow-up time was 35.5 months, with a median interval from OLT to lung metastasis of 15.3 months. The median PFS and OS were 9.9 and 32.7 months, respectively. The 1-, 2-, and 3-year PFS and OS rates were 36.0%, 16.0%, and 12.0%, and 84.0%, 52.0%, and 20.0%, respectively. The LCR of pulmonary metastases at 1 year was 100%, whereas the two-year LCR was 76.9%. The 1- and 2- year ORRs were 95.2% and 69.2%, respectively, with no grade > 2 adverse events. Radiation pneumonitis was observed in 17 patients (68.0%). Grade 1 pneumonitis occurred in 15 patients (60.0%), and grade 2 pneumonitis occurred in 2 patients (8.0%). CONCLUSION The combination therapy of HFRT with TKIs is a feasible, safe, and promising approach in the treatment of pulmonary metastases for HCC after OLT.

Abstract
PURPOSE/OBJECTIVE(S) The anti-tumor activity and tolerability of stereotactic body radiotherapy (SBRT) and PD-1 inhibitors have been illustrated in retrospective studies, but the results vary across a broad range. This study aimed to assess the clinical efficacy of SBRT combined with sintilimab in patients with recurrent or oligometastatic hepatocellular carcinoma (HCC). MATERIALS/METHODS This trial involved patients with recurrent or oligometastatic HCC intravenously treated with SBRT plus sintilimab every 3 weeks for 12 months or until disease progression. The primary endpoint was progression-free survival (PFS). RESULTS Twenty-five patients were enrolled from August 14, 2019, to August 23, 2021. The median treatment duration was 10.2 months. SBRT was delivered at a median dose of 54 in six fractions. The median follow-up time was 21.9 months, and 32 targeted lesions among 25 patients were evaluated for treatment response according to the Response Evaluation Criteria in Solid Tumors version 1.1. The median PFS was 19.7 months, with PFS rates of 68% and 45.3% at 12 and 24 months, respectively. The median overall survival (OS) was not reached, with OS rates of 91.5% and 83.2% at 12 and 24 months, respectively. The 1- and 2-year local control rate were 100% and 90.9%, respectively. The confirmed objective response rate and disease control rate was 96%, and 96%, respectively. Most adverse events were graded as 1 or 2, and grade 3 adverse events were observed in three patients. CONCLUSION SBRT plus sintilimab is an effective, well-tolerated treatment regimen for patients with recurrent or oligometastatic HCC.

Abstract
The objective of this study was to investigate effects of anthocyanins (AC) and microbial transglutaminase (MTGase) on the physicochemical properties of surimi gels from silver carp. The addition of AC and MTGase significantly increased gel strength and water holding capacity (WHC) of surimi gels, but the effect of MTGase was much stronger (p < .05). There were the highest gel strength, storage modulus (G') and WHC with 0.1 g/100 g AC and 0.4 g/100 g MTGase, while they were higher than that with AC or MTGase alone. AC promoted the cross-linking mainly by covalent and non-covalent bonds in surimi gels, while MTGase did mainly through covalent bonds. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) confirmed the results of gel strength, WHC, chemical interactions and G' of surimi gel or paste with AC and MTGase. In general, AC and MTGase could synergistically improve the physicochemical properties of surimi gels and potentially enhance the quality of surimi-based product from silver carp.

Abstract
Circular RNAs are implicated in the pathogenesis of ischemic stroke. In this work, we explored the modulation and potential mechanisms of action of circ_0005585 in ischemic stroke. Expression of circ_0005585 and miR-16-5p was assessed by quantitative real-time reverse transcription PCR. Ischemic stroke was modeled in mice by middle cerebral artery occlusion (MCAO). The infarct volume was assessed by triphenyl tetrazolium chloride staining. Neurological deficits were evaluated according to Neurological Severity Score. The permeability of the blood-brain barrier was assessed by Evan's blue leakage and brain water content. Apoptosis in brain tissues was measured by the TUNEL test. Relative expression of apoptosis-related proteins was evaluated by Western blotting. The direct interaction between circ_0005585 and miR-16-5p was verified by dual-luciferase reporter assay. The expression of circ_0005585 was lower in mice with MCAO. Lentivirus-mediated overexpression of circ_0005585 ameliorated the neurological deficits and decreased the infarction volume in MCAO mice. The brain water content and Evan's blue leakage through the blood-brain barrier were reduced. In addition, overexpression of circ_0005585 inhibited apoptosis in the cerebral tissues. Our results revealed direct interaction between circ_0005585 and miR-16-5p. Hence, circ_0005585 protects mouse brain during ischemic stroke by targeting miR-16-5p, which uncovers the pathogenesis of this pathology and opens new vitas for its therapy.

Abstract
Cations can combine with starch and alter its physicochemical characteristics. The addition of cations may influence the in vitro digestion of potato starch. Scanning electron microscopy, X-ray diffraction, low-field nuclear magnetic resonance, and Fourier transform infrared spectroscopy were used to measure the microstructure, relative crystallinity, water distribution, and interaction of potato starch with cations and characterize its digestibility. The results showed that all cations decreased rapidly digestible starch (RDS) at a low concentration but increased the RDS with the addition of cations, especially trivalent cations. However, the resistant starch (RS) had the opposite trend. All cations increased the relative crystallinity of potato starch, except Ca2+. Fe3+, and Al3+ markedly decreased the mobility and hydrogen bonds in potato starch. In general, the addition of cations influenced the retrogradation of potato starch, resulting in a change in its digestibility.

Abstract
OBJECTIVE Currently, there are still no convincing clinical models predicting closed lower extremity fracture-associated deep vein thrombosis in patients treated through thromboprophylactic methods. We aimed at using two retrospective cohorts to develop and externally verify a clinical prediction model for deep vein thrombosis in patients treated with anticoagulants after suffering closed lower extremity fractures. PATIENTS AND METHODS We evaluated the patients' pre- and post-operatively, to accurately determine the predictive power of the biomarkers and clinical risk factors. Two retrospective cohorts were used for the development and external verification of a pre-operative clinical prediction model (development: n = 2,253; verification: n = 833) and post-operative clinical prediction model (development: n = 1,422; verification: n = 449), respectively. RESULTS The C-indices were used to show the predicted incidence of objective thrombosis at the pre- and post-operative stage, which were then compared with the observed incidence of thrombosis in both cohorts. Biomarkers and clinical indicators were included in pre- and post-operative nomograms, which were adequately calibrated in both cohorts. The cross-validated C-indices of the pre- and post-operative clinical prediction models in the verification cohort were 0.706 (95% Cl, 0.67-0.74) and 0.875 (95% Cl, 0.84-0.91), respectively. CONCLUSIONS We present our findings of novel pre- and post-operative nomograms for the prediction of deep venous thrombosis in patients who received thromboprophylaxis after suffering closed lower extremity fractures.

Abstract
Shear stress is an important index to evaluate the rheological behavior of magnetorheological fluids (MRFs), which is not only related to the properties of ferromagnetic particles, but also the viscosity of the carrier. However, the research related to the carrier viscosity is quite lacking, and the mechanism of its effect on shear stress is still unclear. In this work, the carrier viscosity effect on the microstructure of MRFs under shearing was investigated via numerical simulations, and the relationship between chain inclination and carrier viscosity was presented for the first time. It was found that the deflection angle of the chain increases with the increase of carrier viscosity. Based on the simulation results, the relationship between the shear resistance induced by the magnetic field and the deflection angle of the chain was studied. Finally, a constitutive model incorporating the mechanism of the viscosity effect on shear stress was proposed, and the calculated results agreed well with the experimental data. This work provides new insights into the effect of carrier viscosity and can help us to better understand the corresponding microscopic mechanism.

Abstract
Objective: To examine the influence of sacroiliac joint reduction quality on the clinical effect of bionic reduction and internal fixation for pelvic ring injury. Methods: From January 2014 to February 2019,the clinical data of 78 patients diagnosed with pelvic ring injury involving sacroiliac joints and treated with bionic reduction and internal fixation at Honghui Hospital Affiliated to Medical College of Xi'an Jiaotong University were retrospectively analyzed.There were 48 males and 30 females,aged (48.3±8.3)years (range:28 to 68 years).After bionic reduction and internal fixation,the patients were grouped according to the maximum displacement distance (d) of sacroiliac joint residual on the damaged side measured by CT examination. Patients with d≤5 mm were included in anatomical bionic reduction group,and patients with d>5 mm were included in non-anatomical bionic reduction group.In non-anatomical bionic reduction group,according to the direction of residual displacement,the patients were divided into separation displacement group and anterior-posterior displacement group. The X-ray examination was performed immediately and at the last follow-up after operation.If sacroiliac joint was relocated,or internal plant loosening,displacement,fracture and re-displacement of fracture,it was defined as internal fixation failure.Majeed pelvic fracture scoring system was used to evaluate the postoperative functional status of the two groups,and visual analogue scale (VAS) was used to evaluate the postoperative pain.Comparison between groups was performed by completely random design ANOVA,χ2 test,Fisher's exact test,Mann-Whitney U and Kruskal-Wallis H test. Results: According to the CT examination,28 cases were included in anatomical bionic reduction group,and 50 cases were included in non-anatomical bionic reduction group.In non-anatomical bionic reduction group,27 cases were divided into separation displacement group and 23 cases were in anterior-posterior displacement group.There was no significant difference in general data among anatomical bionic reduction group,separation displacement group and anterior-posterior displacement group (P>0.05). The follow-up time was (37.8±6.6) months (range:25 to 51 months). At the last follow up,the excellent and good rate of Majeed score in anatomical bionic reduction group was 96.4%(27/28),which was better than that in separation displacement group(74.1%(20/27)) and anterior-posterior displacement group (30.4%(7/23)),the difference was statistically significant (Z=-6.479,P<0.01;Z=-6.256,P<0.01); and the good rate of the separation displacement group was better than that of the anterior-posterior displacement group(Z=-3.607,P<0.01).The VAS of anatomical bionic reduction group (17 cases with 0 point, 11 cases with 1 to 3 points) were lower than that of the displacement group (6 cases with 0 point,16 cases with 1 to 3 points,5 cases with 4 to 6 points) and anterior-posterior displacement group (3 cases with 0 point,7 cases with 1 to 3 points,13 cases with 4 to 6 points),the difference was statistically significant (Z=-3.515,P<0.01;Z=-3.506,P<0.01),and there was no difference between separation displacement group and anterior-posterior displacement group.Total of 8 cases of internal fixation failure occurred,and the failure rate of anatomical bionic reduction group (0,0/28) was lower than that of the separation displacement group (11.1%,3/27) and anterior-posterior displacement group (21.7%,5/23) (P=0.111,P=0.014),and there was no difference between separation displacement group and anterior-posterior displacement group(P=0.444). Conclusions: In the bionic reduction and internal fixation of pelvic fracture involving sacroiliac joint injury,the functional status,pain and internal fixation failure rate of patients with anatomical bionic reduction of sacroiliac joint are significantly better than those in the non-anatomical bionic reduction.The functional recovery of patients with separation displacement is better than that of the patients with anterior and posterior displacement.

Abstract
Background: We and others have previously demonstrated that glycine is neuroprotective in cerebral ischemia-reperfusion injury. But glycine has low permeability to the blood–brain barrier (BBB). To deliver glycine into the ischemic brain to confer neuroprotection, we designed a novel glycine-containing and BBB-permeable tripeptide, the H-glycine-cysteine-phenylalanine-OH (GCF). Methods: For the synthesis of GCF, phenylalanine was included to increase the BBB permeability of the tripeptide. Cysteine was conjugated with glycine to enable the release of glycine from GCF. With the use of immunofluorescence labeling and HPLC assays, we measured the distribution and level of GCF. We used TTC labeling, LDH release, and MTT assays to evaluate the neuroprotective effect of GCF. Results: Following intravenous injection in a rat model of cerebral ischemia-reperfusion injury, GCF was intensively distributed in the ischemic neurons. Intravenous injection of GCF, but not the non-cleavable acetyl-GCF, resulted in the elevation of glycine in the ischemic brain. GCF but not acetyl-GC conferred neuroprotection in ischemic stroke animals. Conclusion: GCF protects against cerebral ischemia-reperfusion injury in the rat. In contrast to peptide drugs that exert therapeutic effect by interfering with signaling interaction, GCF acts as a BBB shuttle and prodrug to deliver glycine to confer neuroprotection, representing a novel therapeutic strategy for acute ischemic stroke.

Abstract
Objective: To investigate the effects of high-flow nasal oxygen (HFNO) combined with early extubation on the incidence of respiratory adverse events (RAE) during emergence from general anesthesia in children undergoing adenoid-tonsillectomy. Methods: From December 2021 to January 2022, 40 pediatric patients [21 males, 19 females, with a median age of 4 (4, 5) years] undergoing tonsillectomy and/or adenoidectomy in Eye & ENT Hospital of Fudan University were randomly divided into two groups: HFNO-assisted early extubation group (Group H, n=20) and conventional extubation group (Group C, n=20) by using a random number table. After entering the post-anesthesia care unit (PACU), the patients in group H received humidified and heated oxygen (flow rate: 25 L/min) through a nasal cannula until their consciousness regained. After patient's spontaneous breathing resumed for 10 min, the oral endotracheal tube was removed. Patients in group C did not receive HFNO. The oral endotracheal tube was removed after the patient's spontaneous breathing resumed for at least 10 min with signs of tube intolerance, or 20 min without signs of tube intolerance. During the PACU stay, the incidence of RAE, the incidence of cough, the application rate of intensive care strategy, the time to extubation, the duration of PACU stay, and vital signs at spontaneous breathing resuming and extubation in each group were recorded. Results: In Group H, the total incidence of RAE [30% (6/20) vs 65% (13/20), P=0.027], the incidence of cough [10% (2/10) vs 45% (9/20), P=0.031] and the application rate of intensive care strategy [20% (4/20) vs 55% (11/20), P=0.048] during PACU stay was significantly lower, compared with those of Group C. Likewise, the time to extubation was significantly shorter [(33.4±4.5) min vs (42.7±5.3) min, P<0.001]. However, there was no statistically significant difference in the duration of PACU stay, the vital signs at the time of spontaneous breathing resuming and extubation between the two groups (P>0.05), except that the end-tidal carbon dioxide partial pressure (PETCO2) at the time of extubation in group H was significantly higher than group C [(52.9±9.4) mmHg vs (48.9±3.1) mmHg (1 mmHg=0.133 kPa), P<0.001]. Conclusion: HFNO combined with early extubation can significantly reduce the incidence of RAE in children undergoing adenoid-tonsillectomy during the emergence from general anesthesia.

Abstract
Objective: To investigate the sensitization characteristics of Juniperus chinensis pollen in patients with allergic rhinitis and/or allergic asthma in Beijing area, and to explore the characteristics of Juniper chinensis pollen sensitized population. Methods: Patients with suspected allergic rhinitis and/or asthma from January 2017 to December 2019 in the outpatient department of Allergy Department of Beijing Shijitan Hospital were selected in this study. Skin prick test (SPT) was performed with Juniper chinensis pollen allergen reagent to compare different age and disease allergen distribution, and to observe the sensitization characteristics of its population. All of the analyses were performed using SAS software version 9.4. Results: A total of 8 380 patients were enrolled in the end. The total positive rate of Juniper chinensis pollen SPT reached 49.92% (4 183/8 380). The positive rate of Juniper chinensis pollen SPT was highest in the 10-14 age group, reaching 60.99% (283/464). Compared with other age groups, there was a statistical difference (χ²=266.77, P<0.01). The SPT positive rate of patients aged less than 10 years increased with the increase of age, while the SPT positive rate of patients aged over 40 years decreased with the increase of age. Single Juniper chinensis pollen was less allergenic, accounting for about 25.05% (1 048/4 183), and the patients' age was (35.21±12.39) years. Regardless of single Juniper chinensis pollen or other pollen allergies, allergic rhinitis was the main disease. Among the patients with SPT positive Juniper chinensis pollen combined with other inhaled pollen allergens, willow pollen accounted for the first (74.99%). The positive rate of Juniper chinensis pollen was the highest in patients with single allergic rhinitis, accounting for 52.05% (3 797/7 295), and the rate in patients with single allergic asthma was the lowest, accounting for 17.49% (53/303), with statistically difference (χ²=138.99, P<0.01). Conclusions: Juniper chinensis pollen is highly sensitized in patients with allergic rhinitis and/or allergic asthma in Beijing . The positive rate of SPT is highest among 10-14 age group, most of which showed strong positive reaction, and allergic rhinitis is more common in Juniper chinensis pollen sensitization diseases.

Abstract
Telomerase plays a pivotal role in tumorigenesis by both telomere-dependent and telomere-independent activities, although the underlying mechanisms are not completely understood. Using single-sample gene set enrichment analysis (ssGSEA) across 9,264 tumour samples, we observe that expression of telomerase reverse transcriptase (TERT) is closely associated with immunosuppressive signatures. We demonstrate that TERT can activate a subclass of endogenous retroviruses (ERVs) independent of its telomerase activity to form double-stranded RNAs (dsRNAs), which are sensed by the RIG-1/MDA5-MAVS signalling pathway and trigger interferon signalling in cancer cells. Furthermore, we show that TERT-induced ERV/interferon signalling stimulates the expression of chemokines, including CXCL10, which induces the infiltration of suppressive T-cell populations with increased percentage of CD4+ and FOXP3+ cells. These data reveal an unanticipated role for telomerase as a transcriptional activator of ERVs and provide strong evidence that TERT-mediated ERV/interferon signalling contributes to immune suppression in tumours.

Abstract
The digestive tract development in goat kids around weaning is vital to the establishment of digestion and absorption function, growth, and health of adults. The objective was to explore the effects of age and solid feed on the anatomical and morphological development of the gastrointestinal tract of Laiwu Black goat kids. Forty-eight female Laiwu Black goats at 8 ages (1, 7, 14, 28, 42, 56, 70, and 84 d; 6 goats per group) were selected and killed for anatomical and morphological analysis. The goats experienced the following 4 diet phases: maternal colostrum (MC; d 1, d 7), maternal milk (MM; d 14, d 28), maternal milk plus solid diet (MMSD; d 42, d 56) and only solid diet (OSD; d 70, d 84). The body and carcass weights were not significantly changed during MC and MM phases but changed during the MMSD phase. The absolute growth of body and carcass weights were higher in the MMSD phase than in MM phase. In addition, the dressing percentage was the highest in the MMSD phase. The body size indices evolved progressively and increased over time. The percentage of internal and external organs to body weight decreased over time, whereas the percentage to complex stomach percentage increased. The rumen and omasum weight experienced synchronous absolute growth over time, especially in the OSD phase. In contrast, the absolute growth of the reticulum and abomasum was the highest in MMSD and MC phases, respectively. After weaning, the goats showed the highest papillae height, lamina propria, muscle layer thickness, and epithelial thickness. The OSD phase showed the highest colonic mucosa thickness, ileal villus height, and ileal muscle layer thickness. The crypt depth was higher in the MMSD phase than in the MM phase. Moreover, the crypt depth and muscle layer thickness of jejunum increased over time. Furthermore, duodenal crypt depth, muscle layer thickness, and epithelial thickness increased in the OSD phase compared with other stages. In conclusion, the histological investigation supports the improvement of the morphological development of the digestive tract and the growth performance in the solid feed phase. It is recommended to add solid food as early as 4 wk old.

Abstract
Severe microenvironmental changes after spinal cord injury (SCI) present serious challenges in neural regeneration and tissue repair. Gelatin (GL)- and hyaluronic acid (HA)-based hydrogels are attractive scaffolds because they are major components of the extracellular matrix and can provide a favorable adjustable microenvironment for neurogenesis and motor function recovery. In this study, three-dimensional hybrid GL/HA hydrogel scaffolds were prepared and optimized. The hybrid hydrogels could undergo in-situ gelation and fit the defects perfectly via visible light- induced crosslinking in the complete SCI rats. We found that the transplantation of the hybrid hydrogel scaffold significantly reduced the inflammatory responses and suppressed glial scar formation in an HA concentration-dependent manner. Moreover, the hybrid hydrogel with GL/HA ratios less than 8/2 effectively promoted endogenous neural stem cell migration and neurogenesis, as well as improved neuron maturation and axonal regeneration. The results showed locomotor function improved 60 days after transplantation, thus suggesting that GL/HA hydrogels can be considered as a promising scaffold for complete SCI repair.

Abstract
OBJECTIVE To investigate the pharmacodynamic mechanism of curcumin against myocardial ischaemia-reperfusion injury by regulating the phosphatidylinositol-3 kinase (PI3K)/protein kinase B (AKT)/rapamycin target protein (mTOR) signalling pathway. MATERIALS AND METHODS The left anterior descending coronary artery was ligated for 30 min and reperfused for 3 h to establish an ischaemia-reperfusion injury model. The electrocardiogram (ECG) detection of rats was performed, and the degree of myocardial infarction was determined by 2,3,5-triphenyltetrazolium chloride staining. The expression levels of serum creatine kinase isoenzyme (CK), lactate dehydrogenase (LDH), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), malondialdehyde (MDA), nitric oxide (NO) and other related indicators were detected. The protein expressions of mTOR, phosphorylated (p)-mTOR, AKT and p-AKT were detected by Western blotting, whereas the expressions of Bcl-2 and Bax were detected by real-time polymerase chain reaction. RESULTS The results showed that compared with the model group, curcumin could improve the ECG findings, reduce the scope of myocardial infarction, reduce the expression levels of CK-MB, LDH, AST, MDA, NO and increase those of SOD and GSH. Curcumin can also down-regulate the expression of Bax and up-regulate the protein levels of Bcl2, p-mTOR and p-AKT (p < 0.05 or p < 0.01). CONCLUSIONS This study shows that curcumin has a significant protective effect on myocardial ischaemia-reperfusion, and its mechanism may be related to the activation of PI3K/AKT/mTOR signalling pathway and inhibition of inflammation, apoptosis and oxidative stress.

Abstract
Objective: To investigate the incidence and trend of severe postpartum hemorrhage (sPPH) in China, and to provide basic data for the development and evaluation of sPPH prevention and control strategy. Methods: Obstetric data was extracted from annual national representative sampling surveys based on the National Clinical Improvement System. From 2016 to 2019, 2 978, 3 400, 4 576 and 4 594 maternity hospitals with sPPH cases were included for statistics. The annual incidence of sPPH was calculated according to province and type of medical institutions and generalized linear model was emplyed to identify the determinants affecting sPPH incidence. Results: In China, sPPH incidence increased from 0.62% in 2016 to 0.93% in 2018, and was 0.92% in 2019. Eighteen provinces had an inverted U-shaped trend of sPPH over time and most of them had the highest incidence in 2018; ten provinces had an upward trend of sPPH and 3 provinces had a U-shaped trend. In 2019, the top five provinces with the highest sPPH incidence were Yunnan (1.88%), Beijing (1.45%), Jiangsu (1.31%), Guizhou (1.26%), and Ningxia Hui Autonomous Region (1.22%); the top five provinces with the lowest incidence were Henan (0.55%), Jiangxi (0.60%), Inner Mongolia Autonomous Region (0.64%), Liaoning (0.64%) and Gansu (0.69%). In 2019, the sPPH incidence in different types of medical institutions were as follows: tertiary public general hospital (1.15%), tertiary public specialized hospital (1.02%), secondary public general hospital (0.81%), private hospital (0.61%) and secondary public specialized hospital (0.58%). sPPH incidence was positively associated with proportion of twin pregnancies, macrosomia, primipara, and puerpera aged ≥35 years in maternity hospitals (P<0.05). Conclusions: sPPH incidence generally showes an increasing trend from 2016 and is stable at a high level in recent two years in China. It is warranted to further strengthen the monitoring of postpartum hemorrhage, and improve the capability of hierarchical management and treatment in maternity institutions and regions, in order to reduce sPPH incidence and maternal mortality.

Abstract
OBJECTIVE The aim of the study was to examine the influence of femoral shaft fracture on systemic inflammation and gut microbiome in adolescent rats and evaluate the anti-inflammatory effect of Lactobacillus rhamnosus GG (LGG) and its regulation of intestinal flora, as well as illustrate the mechanism by which LGG ameliorates the inflammatory response and restores intestinal dysbacteriosis. MATERIALS AND METHODS Twenty-four male Sprague Dawley rats of 5 to 6 weeks of age were subjected to a standard femoral shaft fracture and internally fixed with LGG supplementation in advance or on the same day of injury or with saline solution for 1 week. The levels of TNF-α, IL-6, IL-10, and CRP were assessed using standard protocols. Furthermore, gut microbiota composition was analyzed in the fecal samples using 16S rDNA gene sequencing, and the relationship between gut microbiota variation and inflammatory response was tested. RESULTS The serum indices of the above-mentioned inflammatory cytokines were significantly increased, and the gut microbial balance was significantly disturbed in adolescent rats by diaphyseal fractures of the femur and surgery. Moreover, L. rhamnosus strains manipulated the gut microbiota by decreasing the relative abundance of Proteobacteria and increasing that of Firmicutes, Actinobacteria and Bacteroidetes, which in turn increased the levels of IL-10 and alleviated the levels of IL-6, CRP, and TNF-α. CONCLUSIONS LGG exhibited anti-inflammatory effects by alleviating the inflammatory response and regulating the gut microbiota in adolescent rats who underwent skeletal fracture and surgery. Our results suggested that the L. rhamnosus strains could be considered as an alternative dietary supplement for the prevention or treatment of skeletal injury and its associated complications.

Abstract
OBJECTIVE The aim of this study is to explore the regulatory mechanism of circRNA UBAP2 (circUBAP2) in colorectal cancer (CRC). PATIENTS AND METHODS The expression levels of circUBAP2, miR-199a, and VEGFA in tissues and cell lines were detected by RT-qPCR. The cell proliferation was examined by CCK-8 and colony formation assays. The migration and invasion abilities were evaluated by wound healing and transwell assays, respectively. Bioinformatics analysis and Luciferase activity assay were applied to determine the interaction between genes. RESULTS The expression of circUBAP2 was upregulated in CRC tissues and cell lines, and depletion of circUBAP2 suppressed the cell proliferation, migration, and invasion of CRC. Furthermore, miR-199a inhibitor abrogated the suppressive effect of circUBAP2 knockdown on CRC progression. Vascular endothelial growth factor A (VEGFA) was identified as a downstream target gene of miR-199a, and overexpression of VEGFA rescued the tumor phenotypes attenuated by circUBAP2 knockdown or miR-199a overexpression. CONCLUSIONS Our findings demonstrated that circUBAP2 facilitated CRC progression by sponging miR-199a to upregulate VEGFA. These findings implied that circUBAP2 may be a potential therapeutic biomarker for CRC.

Abstract
OBJECTIVE The aim of this study was to investigate the effects of long non-coding ribonucleic acid regulator of reprogramming (lncRNA ROR) on the proliferation and apoptosis of endometrial cancer (EC) cells, and to explore its possible underlying mechanism. PATIENTS AND METHODS The expression levels of lncRNA ROR and Notch1 in EC tissues were detected via quantitative reverse transcription-polymerase chain reaction (qRT-PCR). The changes in Notch1 protein were detected via Western blotting. Subsequently, the regulatory mechanism of lncRNA ROR on Notch1 was analyzed using Luciferase reporter gene assay. Moreover, the changes in cell proliferation and apoptosis were determined through cell counting kit-8 (CCK-8) assay and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay, respectively. RESULTS Both lncRNA ROR and Notch1 were highly expressed in EC tissues (p<0.05). After overexpression of lncRNA ROR, HEC-1A cells had significantly enhanced proliferation (p<0.05) and weakened apoptosis (p<0.05). Meanwhile, the mRNA and protein levels of Notch1 rose remarkably compared with those in control group (p<0.05). Luciferase reporter gene assay revealed that lncRNA ROR could bind to the Notch1 regulatory factor miR-34a and inhibit its activity. CONCLUSIONS LncRNA ROR regulates the proliferation and apoptosis of EC cells via promoting the expression of Notch1 protein.

Abstract
AIM To evaluate the association between perihaematomal radiomics features and haematoma expansion (HE). MATERIALS AND METHODS Clinical and radiological data were collected retrospectively. The 1:1 propensity score matching (PSM) method was used to balance the difference of baseline characteristics between patients with and without HE. Radiomics features were extracted from the intra- and perihaematomal regions. Top HE-associated features were selected using the minimum redundancy, maximum relevancy algorithm. Support vector machine models were used to predict HE. Predictive performance of radiomics features from different regions was evaluated by receiver operating characteristic curve and confusion matrix-derived metrics. RESULTS A total of 1,062 patients were enrolled. After PSM analysis, the propensity score-matched cohort (PSM cohort) included 314 patients (HE: n=157; non-HE: n=157). The PSM cohort was distributed into the training (n=218) and the validation cohorts (n=96). The predictive performance of intra- and perihaematomal features were comparable in the training (area under the receiver operating characteristic curve [AUC], 0.751 versus 0.757; p=0.867) and the validation cohorts (AUC, 0.724 versus 0.671; p=0.454). By incorporating intra- and perihaematomal features, the combined model outperformed the single intrahaematomal model in the training cohort (AUC, 0.872 versus 0.751; p<0.001). Decision curve analysis (DCA) further confirmed the clinical usefulness of the combined model. CONCLUSION Perihaematomal radiomics features can predict HE. The integration of intra- and perihaematomal signatures may provide additional benefit to the prediction of HE.

Abstract
We reviewed studies comparing survival outcomes such as overall survival (OS), progression free survival (PFS), and toxicity profile between patients treated with Pegylated Liposomal Doxorubicin (PLD) combination and those treated with paclitaxel combination for ovarian cancer. We conducted systematic searches in various databases including Medline, Cochrane Controlled Register of Trials (CENTRAL), ScienceDirect, and Google Scholar from inception until August 2019. We used the Cochrane risk of bias tool to assess the quality of published trials. We carried out a meta-analysis with random-effects model and reported pooled Hazard ratios (HR) or Risk ratios (RR) with 95% confidence intervals (CIs). In total, we analysed 7 studies including 3,676 participants. All the studies were randomized controlled trials, while majority of studies had low bias risks. We did not find significant evidence for any of these outcomes except progression free survival (favoured PLD combination therapy pooled HR=0.87; 95% CI: 0.77-0.98). Worst grade toxicities like allergy (pooled RR: 1.86; 95% CI: 1.06-3.24) and neurotoxicity (pooled RR: 5.59; 95% CI: 1.43-21.84) were significantly higher among patients receiving paclitaxel combination therapy when compared to patients receiving PLD combination therapy. To summarize, PLD combination therapy is non-inferior to paclitaxel combination therapy in the management of ovarian cancer with respect to survival outcomes and worst grade toxicity profile. However, clinical recommendations cannot be made, as the evidence is not conclusive or significant enough.

Abstract
PURPOSE The aim of this study was to identify and characterize immune checkpoint inhibitors (ICIs)-associated pituitary adverse events (AEs). METHODS This is a retrospective disproportionality study based on VigiBase, the World Health Organization (WHO) global database of individual case safety reports (ICSRs), with a study period from January 1, 2011 to March 6, 2019. Information component (IC) and reporting odds ratio (ROR) are measures of disproportionate analysis. IC was used to evaluate the association between ICIs and pituitary AEs, while ROR was used to evaluate the differences in reporting of pituitary AEs between different ICI subgroups. RESULTS The following ICI-associated pituitary diseases have been increasingly reported: hypophysitis (835 reports; information component 6.74 [95% CI 6.63-6.83]), hypopituitarism (268; 6.12 [95% CI 5.92-6.27]), pituitary enlargement (28; 5.19 [95% CI 4.57-5.63]). The anti-CTLA-4 subgroup had a stronger association with hypophysitis/hypopituitarism than the anti-PD (anti-PD-1 or anti-PD-L1) subgroup (ROR 8.0 [95% CI 6.7-9.6]). Among ICI-associated hypophysitis/hypopituitarism cases, the proportion of male was higher than female (630 [63.9%] vs 356 [36.1%]). Anti-CTLA-4 subgroup and ICI combination (nivolumab plus ipilimumab) subgroup both had a significantly earlier onset time than anti-PD subgroup (67 days [IQR 48-87]; 90 [IQR 34-155]; 140 [IQR 62-218], both p < 0.05). Other endocrinopathies that co-occurred with hypophysitis/hypopituitarism were adrenal insufficiency, thyroid dysfunction, diabetes mellitus and diabetes insipidus. Gastrointestinal disorder was the most common concurrent disease except for endocrinopathies. CONCLUSIONS ICI-associated pituitary adverse events have significantly increased, and their clinical characteristics should be kept in mind by oncologists and endocrinologists who manage patients treated by immunotherapy.

Abstract
Neuroinflammation is a secondary response following ischemia stroke. Arginine is a non-essential amino acid that has been shown to inhibit acute inflammatory reaction. In this study we show that arginine treatment decreases neuronal death after rat cerebral ischemia/reperfusion (I/R) injury and improves functional recovery of stroke animals. We also show that arginine suppresses inflammatory response in the ischemic brain tissue and in the cultured microglia after OGD insult. We further provide evidence that the levels of HIF-1α and LDHA are increased after rat I/R injury and that arginine treatment prevents the elevation of HIF-1α and LDHA after I/R injury. Arginine inhibits inflammatory response through suppression of HIF-1α and LDHA in the rat ischemic brain tissue and in the cultured microglia following OGD insult, and protects against ischemic neuron death after rat I/R injury by attenuating HIF-1α/LDHA-mediated inflammatory response. Together, these results indicate a possibility that arginine-induced neuroprotective effect may be through the suppression of HIF-1α/LDHA-mediated inflammatory response in microglia after cerebral ischemia injury.

Abstract
OBJECTIVE Free-hand technique is widely used in pedicle screw placement for lumbar spine and generally safe; however, screw malposition still occurs. To develop a novel multi-level drill guide template for pedicle screw placement in lumbar spine and evaluate its accuracy. MATERIALS AND METHODS Twelve lumbar cadaveric specimens were randomly allocated into guide template group (n=6) and free-hand group (n=6). Computed tomography (CT) scans were obtained for reconstruction of three-dimensional (3D) model of each lumbar vertebra, and further an individual guide template was designed. Then the templates and their corresponding vertebra were developed by rapid prototyping (RP) technology. With the guide of the templates, screws were inserted via mini-open Wiltse approach. The positions of the screws were assessed based on postoperative CT images. RESULTS In total, 120 pedicle screws inserted (guide template group: n=60 vs. free-hand group: n=60). For all 30 vertebras in the guide template group, all pre-designed personalized drill guide templates can be fitted into the facet joints of each vertebra well. Furthermore, our results revealed a significant improvement for the guide template group in the accuracy rate (p=0.026). CONCLUSIONS Armed with advantages of minimal invasion, enhanced accuracy and safety, the novel technique of multi-level drill guide template can be properly applied in pedicle screw placement for lumbar spine and promises to be a potential option in clinical application.

Abstract
OBJECTIVE To investigate the role of microRNA-337-5p in osteosarcoma (OS) and its underlying mechanism. PATIENTS AND METHODS The microRNA (microRNA-337-5p) that may be related to OS development was screened out by GEO (Gene Expression Omnibus) database. Survival analysis and ROC curve were performed according to microRNA-337-5p expressions in OA patients. Besides, the correlation between microRNA-337-5p expression and clinical parameters was evaluated by Chi-square analysis. Cox regression analysis was performed to detect the relationship between the overall survival and clinical parameters of OA patients. Subsequently, enriched functions and pathways of microRNA-337-5p were predicted by GESA (gene enrichment sets analysis). MicroRNA-337-5p expression was detected in 65 OS tissue samples and 30 normal tissue samples by qRT-PCR (quantitative Real-Time Polymerase Chain Reaction). For in vitro experiments, after microRNA-337-5p mimics or microRNA-337-5p inhibitor was transfected into OS cells, proliferative and invasive abilities were detected by CCK-8 (Cell Counting Kit-8) and transwell assay, respectively. Finally, Western blot was used to explore the underlying mechanism of microRNA-337-5p in regulating OS. RESULTS MicroRNA-337-5p was overexpressed in serum and tissue samples of OS patients, which was valuable in diagnosing OS. Besides, microRNA-337-5p expression was correlated with the overall survival and necrosis range of OA patients, whereas not correlated with age and sex. GESA indicated that microRNA-337-5p was enriched in ERBB, MAPK, and VEGF pathways. In vitro experiments indicated elevated proliferative and invasive abilities in MG63 and U2OS cells after microRNA-337-5p overexpression. Furthermore, increased expressions of ERBB2, Erk1/2, and VEGF121 were observed in OS cells after microRNA-337-5p overexpression. CONCLUSIONS MicroRNA-337-5p is upregulated in OS tissues, which is an independent prognostic factor in OS. Overexpressed microRNA-337-5p can promote proliferative and invasive abilities of OS cells via activating ERBB, MAPK, and VEGF pathways.

Abstract
DJ-1 (also called PARK7) is a multifunctional redox-sensitive protein that is protective against oxidative stress-induced cell death. TAR DNA-binding protein 43 (TDP-43) is a major protein component of pathological inclusions in amyotrophic lateral sclerosis and frontotemporal dementia. Reducing aberrant aggregation of TDP-43 is a potential approach to prevent cell death. To investigate whether DJ-1 might inhibit TDP-43 aggregation to exert a protective effect in oxidative stress-induced injury, we tested the protein level and subcellular localization of TDP-43 and DJ-1 in SH-SY5Y cells transfected with wild-type DJ-1, DJ-1 mutant (L166P) cDNA, or DJ-1 siRNA. We show that oxidative stress induced by paraquat leads to the formation of cytosolic TDP-43 aggregation in SH-SY5Y cells. DJ-1 overexpression decreases paraquat-induced cytoplasmic accumulation of TDP-43 in SH-SY5Y cells and protects against paraquat-induced cell death. Transfection of DJ-1 L166P mutant or DJ-1 siRNA leads to increased cytosolic aggregation of TDP-43 in paraquat-treated SH-SY5Y cells and promotes cell death. These data suggest that DJ-1 may protect against oxidative stress-induced cell death through the suppression of cytoplasmic TDP-43 aggregation.

Abstract
Objective: To understand the seasonality and etiological characteristics of infectious diarrhea in adults from Shanghai. Methods: Adult patients with diarrhea who had visited the enteric disease clinics in 22 hospitals that carrying on the Diarrhea Comprehensive Surveillance sentinel programs in Shanghai during 2014-2017, were surveyed. Stool specimens were collected according to the different intervals of sampling and detected for 12 bacteria and 5 viruses. Concentration ratio and circular distribution method were used for data analysis. Results: From 2014 to 2017, a total of 9 573 stool specimens were collected from the targeted diarrhea patients ≥18 years old (n=96 067), through the Shanghai Diarrhea Comprehensive Surveillance program. The positive rate of detection was 46.44%. Seasonal peaks of infectious diarrhea were both seen in summer (bacteria peak, diarrheagenic Escherichia coli and Vibrio parahaemolyticus, etc.) and in winter (virus peak, Norovirus, etc.). Both bacterial and viral infections presented seasonal concentration (Raleigh's test P<0.001) but more obvious with bacterial infection. Viral infection accounted for 60.19% of the cause of infectious diarrhea. The top five predominant pathogens appeared as Norovirus, Rotavirus, diarrheagenic Escherichia coli, Vibrio parahaemolyticus, and Salmonella spp.. Conclusions: Among the adult outpatients with infectious diarrhea in Shanghai, obvious seasonality was seen, with peaks in both summer and winter. Viral infection with Norovirus in particular, appeared as the predominant source of infection. Active, continuous and comprehensive diarrhea-related surveillance programs would be able to monitor the changing dynamic of pathogen spectrum, and lead to the adoption of targeted preventive measures.

Abstract
Background: The authors have recently designed a new compound bisperoxovandium (pyridin-2-squaramide) [bpV(pis)] and verified that bpV(pis) confers neuroprotection through suppressing PTEN and activating ERK1/2, respectively. Intracerebral hemorrhage (ICH) is the second most common cause of stroke and has severe clinical outcome. In this study, we investigate the effect of bpV(pis) in ICH model both in vivo and in vitro. Materials and methods: The novel drug bpV(pis) was synthesized in the Faculty of Pharmacy, Wuhan University School of Medicine. An ICH model was generated on both SD rats and cells. bpV(pis) was injected into intracerebroventricular or culture media. Western blotting was applied to test the signal pathway. To determine the effect of bpV(pis) on PTEN inhibition and ERK1/2 activation, we measured the phosphorylation level of AKT (a direct downstream target of PTEN that negatively regulates AKT) and ERK1/2. FJC, MTT, and LDH were applied to measure the cell viability. Neurobehavioral tests were performed to measure the effect of bpV(pis). Results: The in vivo results showed that intracerebroventricular administration of bpV(pis) significantly alleviates hematoma, the damage of brain–blood barrier and brain edema. The in vitro results demonstrated that bpV(pis) treatment reduces ICH-induced neuronal injury. Western blotting results identified that bpV(pis) exerts a neuroprotective effect by significantly increasing the phosphorylation level of AKT and ERK1/2 after experimental ICH. Neurobehavioral tests indicate that bpV(pis) promotes functional recovery in ICH animals. Conclusion: This study provides first and direct evidence for a potential role of bpV(pis) in ICH therapy.

Abstract
A batch culture experiment was conducted to study the interactive effects of ocean acidification (OA) and solar ultraviolet radiation (UVR, 280-400 nm) on the harmful dinoflagellate Karenia mikimotoi. Cells were incubated in 7-days trials under four treatments. Physiological (growth, pigments, UVabc) and toxicity (hemolytic activity and its toxicity to zebrafish embryos) response variables were measured in four treatments, representing two factorial combinations of CO2 (400 and 1000 μatm) and solar irradiance (with or without UVR). Toxic species K. mikimotoi showed sustained growth in all treatments, and there was not statistically significant difference among four treatments. Cell pigment content decreased, but UVabc and hemolytic activity increased in all HC treatments and PAB conditions. The toxicity to zebrafish embryos of K. mikimotoi was not significantly different among four treatments. All HC and UVR conditions and the combinations of HC*UVR (HC-PAB) positively affected the UVabc, hemolytic activity in comparison to the LC*P (LC-P) treatment, and negatively affected the pigments. Ocean acidification (OA) was probably the main factor that affected the chlorophyll-a (Chl-a) and UVabc, but UVR was the main factor that affected the carotenoid (Caro) and hemolytic activity. There were no significant interactive effects of OA*UVR on growth, toxicity to zebrafish embryos. If these results are extrapolated to the natural environment, it can be hypothesized that this strain (DP-C32) of K. mikimotoi cells have the efficient mechanisms to endure the combination of ocean acidification and solar UVR. It is assumed that this toxic strain could form harmful bloom and enlarge the threatening to coastal communities, marine animals, even human health under future conditions.

Abstract
OBJECTIVE The purpose of our study was to make a comparison between the fixation strength of optimum placed pedicle screw (OS) and re-directionally accurate placed pedicle screw (RS) after lateral pedicle breach. PATIENTS AND METHODS A total of 30 fresh lumbar vertebrae (L1-5) were gained from 6 male or female pigs weighing about 100 kg, which were divided into 2 groups according to different ways of pedicle screws placement: OS group (n=30) and RS group (n=30). MTS machine was employed to detect the screw loosening and axial pullout. We examined seating torque, screw-loosening force, the maximal torque and post-loosening axial pullout in each pedicle screw. RESULTS Maximal insertion torque of OS was (111.6±8.4) N•cm and RS was (79.0±6.3) N•cm, which indicated a significant difference (Z=3.012, p=0.003). Seating torque of OS and RS were (85.9±5.6) N•cm and (60.3±4.8) N•cm separately, and the difference was statistically significant (Z=2.799, p=0.006). Screw loosening force of OS and RS were (75.9±7.0) N and (52.4±6.3) N respectively, and the difference was statistically significant (Z=2.652, p=0.003). Post-loosening axial pullout force of OS and RS were (328.5±11.3) N and (269.1±9.6) N separately, demonstrating that the difference was statistically significant (Z=2.865, p=0.004). CONCLUSIONS RS placement is an alternative for remediation following a lateral wall breach evidenced by significantly decreased seating torque, screw loosening force, the maximal torque and post-loosening axial pullout compared with OS.

Abstract
Objective: To analyze the pathogen spectrum and epidemiological characters of infectious diarrhea cases in Shanghai from July 2013 to June 2015. Methods: From July 2013 to June 2015, using multi-stage sampling to select 22 hospitals as adult diarrhea surveillance sentinels, and 3 district central hospitals together with Shanghai municipal children's hospital as children diarrhea surveillance sentinels. A total of 6 267 diarrhea cases were sampled. The demographic characters, main clinical manifestations and signs of cases were investigated, and stool specimens were collected to conduct the bacteria culture and virus nucleic acid detection. The difference of positive rate of bacteria and virus in different seasons, and age difference of relevant pathogens were compared. Results: Among 6 267 cases, 3 262 (52.05%) were male, and most of them were in 50-69 years group (1 999 cases, 31.90%) and 30-49 years group (1 691 cases, 26.98%). Totally, 2 783 positive specimens were detected out of 6 267 specimens with the positive rate being 44.41%. A total of 7 kinds of bacteria and 5 kinds of viruses were detected. The positive rate for bacterium was 12.61%(790 cases), mainly being vibrio parahaemolyticus (256 cases), diarrheagenic E.coli (239 cases) and salmonella (209 cases). The positive rate for virus was 31.80% (1 993 cases), mainly being norovirus (1 172 cases) and rotavirus (546 cases). The positive rates of viruses in winter of 2013 and 2014 were 57.89%(429 cases) and 62.14%(522 cases) respectively, higher than those of bacterium in the same periods which were 2.43% (18 cases) and 2.86% (24 cases) respectively. The positive rates of bacterium in summer of 2013, 2014 and 2015 were 14.56% (97 cases), 25.29%(258 cases) and 21.21% (49 cases), also higher than those of viruses in the same periods which were 7.51% (50 cases), 8.43%(86 cases) and 11.69% (27 cases) respectively, all of the above differences were statistically significant (P<0.05). The cases of 50-69 years group had the highest positive rate of pathogen, which was 47.57% (951/1 999). Secondly was those of 30-49 years group with 47.13% (797/1 691). Positive rate of pathogen for cases of 0-2 years group was 35.74% (213/596). Conclusion: The pathogen spectrumes of infectious diarrhea in Shanghai are mainly vibrio parahaemolyticus, diarrheagenic E.coli, salmonella, norovirus and rotavirus. The summer and winter season peak was obvious. Specific etiological surveillance and control strategies should be strengthened aiming at focus groups including children and the elderly in different seasons.
