Objective To explore the risk factors for suicidal ideation among the relatives and friends of suicide victims through psychological support hotline.Methods Calls from the relatives and friends of suicide victims to the Beijing psychological support hotline between 2009 and 2023 were included.Their current suicidal ideation was assessed by asking whether they had suicidal thoughts in the past two weeks.Demographic information of the callers was collected and the severity of their depression was assessed using the depression diagnostic screening scale.Interviews were conducted to evaluate distress,sense of hope,history of suicide attempts,and suicide risk factors.Logistic regression analysis was used to explore the risk factors for suicidal ideation among callers.Results A total of 360 cases were included in this study.There were 50.3%(181 cases)of the callers reporting suicidal ideation within 2 weeks before the call.Years of education(OR=0.86,95%CI:0.79-0.94)and high levels of hope(OR=0.19,95%CI:0.11-0.32)were protective factors against suicidal ideation in callers.History of suicide attempts(OR=2.01,95%CI:1.20-3.36),high levels of distress(OR=3.28,95%CI:1.92-5.61),and high levels of depression(OR=1.73,95%CI:1.05-2.84)were independent risk factors for suicidal ideation in callers.Conclusions History of suicide attempts,high levels of distress and high levels of depression among the relatives and friends of suicide victims calling the psychological support hotline are risk factors for their own suicidal ideation.

Antiphospholipid syndrome （APS） is an autoimmune disease characterized by the persistent presence of antiphospholipid antibodies， which are associated with thrombosis and pregnancy-related complications. APS may have adverse effects on female reproductive function by affecting ovarian function， endometrialization， and other mechanisms， and may lead to embryo implantation failure and pregnancy loss during in vitro fertilization and embryo transfer （IVF-ET） treatments. The routine screening and management of APS before IVF-ET in infertile populations remains controversial and requires individualized risk assessment and appropriate management measures to improve the success rate of assisted reproductive technologies （ART） and reduce maternal and fetal risks during pregnancy. This review summarizes the effects of APS on female infertility and outcomes of ART， as well as the management of the population affected by APS， providing new insights for clinical diagnosis and treatment.

Objective:To compare the effect of neoadjuvant chemotherapy vs. concurrent chemoradiotherapy on the target volume and organs at risk for locally advanced bulky (>4 cm) cervical cancer. Methods:From March 1, 2019 to June 30, 2021, 146 patients pathologically diagnosed with cervical cancer were selected and randomly divided into two groups using random number table method: the neoadjuvant chemotherapy (NACT) + concurrent chemoradiotherapy (CCRT) group ( n=73) and CCRT group ( n=73). Patients in the NACT+CCRT group received 2 cycles of paclitaxel combined with cisplatin NACT, followed by CCRT, the chemotherapy regimen was the same as NACT. In the CCRT group, CCRT was given. Statistical description of categorical data was expressed by rate. The measurement data between two groups were compared by Wilcoxon rank-sum test for comparison of two independent samples, and the rate or composition ratio of two groups was compared by χ2 test. Results:Before radiotherapy, GTV in the NACT+CCRT group was (31.95±25.96) cm 3, significantly lower than (71.54±33.59) cm 3 in the CCRT group ( P<0.01). Besides, CTV and PTV in the NACT+CCRT group were also significantly lower compared with those in the CCRT group (both P<0.05). In terms of target volume dosimetry, D 100GTV, D 95CTV, V 100GTV, V 100CTV and V 95PTV in the NACT+CCRT group were significantly higher than those in the CCRT group (all P<0.05). The complete remision (CR) rates in the NACT+CCRT and CCRT groups were 86.3% and 67.6%, with statistical significance between two groups ( P<0.01) . Regarding organs at risk, NACT+CCRT group significantly reduced the dose to the bladder, rectum, small intestine and urethra compared with CCRT group (all P<0.05). Conclusions:NACT can reduce the volume of tumors in patients with large cervical masses, increase the radiation dose to tumors, reduce the dose to organs at risk, and make the three-dimensional brachytherapy easier. Therefore, NACT combined with CCRT may be a new choice for patients with locally advanced cervical cancer with large masses.

OBJECTIVES: To investigate the risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture and establish a nomogram model for predicting the risk of neonatal asphyxia. METHODS: A retrospective study was conducted with 613 cases of neonatal asphyxia treated in 20 cooperative hospitals in Enshi Tujia and Miao Autonomous Prefecture from January to December 2019 as the asphyxia group, and 988 randomly selected non-asphyxia neonates born and admitted to the neonatology department of these hospitals during the same period as the control group. Univariate and multivariate analyses were used to identify risk factors for neonatal asphyxia. R software (4.2.2) was used to establish a nomogram model. Receiver operator characteristic curve, calibration curve, and decision curve analysis were used to assess the discrimination, calibration, and clinical usefulness of the model for predicting the risk of neonatal asphyxia, respectively. RESULTS: Multivariate logistic regression analysis showed that minority (Tujia), male sex, premature birth, congenital malformations, abnormal fetal position, intrauterine distress, maternal occupation as a farmer, education level below high school, fewer than 9 prenatal check-ups, threatened abortion, abnormal umbilical cord, abnormal amniotic fluid, placenta previa, abruptio placentae, emergency caesarean section, and assisted delivery were independent risk factors for neonatal asphyxia (P<0.05). The area under the curve of the model for predicting the risk of neonatal asphyxia based on these risk factors was 0.748 (95%CI: 0.723-0.772). The calibration curve indicated high accuracy of the model for predicting the risk of neonatal asphyxia. The decision curve analysis showed that the model could provide a higher net benefit for neonates at risk of asphyxia. CONCLUSIONS The risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture are multifactorial, and the nomogram model based on these factors has good value in predicting the risk of neonatal asphyxia, which can help clinicians identify neonates at high risk of asphyxia early, and reduce the incidence of neonatal asphyxia.

Objective:To develop an automatic adjustment algorithm of bed height of multi-position lower limb rehabilitation robot, to meet the variety of leg lengths and training modes to avoid the collision between robot and ground. Methods:Six mathematical models of robot bed body height were established for six training modes of multi-position lower limb rehabilitation robot, which were described with leg length and bed tilt angle. The influence was analyzed that mechanical clearance and deflection as well as the jitter error of leg bracket during movement. Furthermore, a software related to these models was developed to automatically adjust the bed height for training. Volunteers were recruited to test actually. Results:The test data of bed height are consistent with the theoretical calculation of six mathematical models. Clearance and deflection did not affect the theoretical results of bed height. The end of robot's lower limb was always above the safe height during rehabilitation training. Conclusion:The automatic adjustment algorithm of bed height has been established, which can ensure that the rehabilitation robot runs at a safe height.

Acteoside is among the most widespread of thedisaccharide caffeoyl esters that are widely distributed in the plant kingdom with diverse biological activities. Recent studies have shown that acteoside has neuroprotective activity in neurodegenerative diseases. This review examines and extrapolates from the recent literature to build support for the use of acteoside in mitigating neuropathy in neurodegenerative disease, including Parkinson ' s disease (PD) and Alzheimer' s disease (AD). We summarize the main pharmacokinetic parameters of acteoside in animals after different administration routes. Meanwhile, we point out both problems and shortcomings, and highlight its future development trend.

As of Apr. 22, 2020, the World Health Organization (2020) has reported over 2.4 million confirmed coronavirus disease 2019 (COVID-19) patients and 169 151 deaths. Recent articles have uncovered genomic characteristics and clinical features of COVID-19 (Chan et al., 2020; Chang et al., 2020; Guan et al., 2020; Zhu et al., 2020), while our understanding of COVID-19 is still limited. As suggested by guidelines promoted by the General Office of National Health Commission of the People's Republic of China (2020) (from Versions 1 to 6), discharged standards for COVID-19 were still dependent on viral real-time polymerase chain reaction (RT-PCR) tests of respiratory specimens, showing that recovered COVID-19 patients with twice negative RT-PCR could meet discharge criteria. Here, we examined two cases in which nucleic acid test results were inconsistent with clinical and radiological findings, leading to suboptimal care.

OBJECTIVE: To investigate the clinical features and outcome of neonatal acute respiratory distress syndrome (ARDS) in southwest Hubei, China. METHODS: According to the Montreux definition of neonatal ARDS, a retrospective clinical epidemiological investigation was performed on the medical data of neonates with ARDS who were admitted to Department of Neonatology/Pediatrics in 17 level 2 or level 3 hospitals in southwest Hubei from January to December, 2017. RESULTS: A total of 7 150 neonates were admitted to the 17 hospitals in southwest Hubei during 2017 and 66 (0.92%) were diagnosed with ARDS. Among the 66 neonates with ARDS, 23 (35%) had mild ARDS, 28 (42%) had moderate ARDS, and 15 (23%) had severe ARDS. The main primary diseases for neonatal ARDS were perinatal asphyxia in 23 neonates (35%), pneumonia in 18 neonates (27%), sepsis in 12 neonates (18%), and meconium aspiration syndrome in 10 neonates (15%). Among the 66 neonates with ARDS, 10 neonates (15%) were born to the mothers with an age of ≥35 years, 30 neonates (45%) suffered from intrauterine distress, 32 neonates (49%) had a 1-minute Apgar score of 0 to 7 points, 24 neonates (36%) had abnormal fetal heart monitoring results, and 21 neonates (32%) experienced meconium staining of amniotic fluid. Intraventricular hemorrhage was the most common comorbidity (12 neonates), followed by neonatal shock (9 neonates) and patent ductus arteriosus (8 neonates). All 66 neonates with ARDS were treated with mechanical ventilation in addition to the treatment for primary diseases. Among the 66 neonates with ARDS, 10 died, with a mortality rate of 15% (10/66), and 56 neonates were improved or cured, with a survival rate of 85% (56/66). CONCLUSIONS Neonatal ARDS in southwest Hubei is mostly mild or moderate. Perinatal asphyxia and infection may be the main causes of neonatal ARDS in this area. Intraventricular hemorrhage is the most common comorbidity. Neonates with ARDS tend to have a high survival rate after multimodality treatment.

【Objective】 To investigate the mechanism of atorvastatin improving ventricular remodeling in rats with myocardial infarction. 【Methods】 Ligation of left anterior descending coronary artery was performed to establish rat model of myocardial infarction. Thirty rats were divided into sham group(n=10), myocardial infarction group(n=10) and atorvastatin group(n=10). Echocardiography was used to examine cardiac function and left ventricular mass index(LVMI) was calculated. The content of arginine vasopressin(AVP) in left ventricular non-infarct area and serum was measured by ELISA. Masson staining was used to observed interstitial fibrosis of myocardium. Immunohistochemistry was used to measure the expression of type Ⅰ collagen. The protein expression of transforming growth factor-β1(TGF-β1) was detected by western blot. 【Results】 After 5 weeks, the number of rats in sham group, myocardial infarction group and atorvastatin group was 10, 9 and 10, respectively. Compared with sham group, LVEF was significantly decreased and, LVMI, interstitial fibrosis, the content of AVP, the expression of type Ⅰ collagen and TGF-β1 in the left ventricular non-infarct area were significantly increased in myocardial infarction group and atorvastatin group(P<0.05). Atorvastatin significantly increased LVEF and decreased interstitial fibrosis, the content of AVP, the expression of type Ⅰ collagen and TGF-β1 in the left ventricular non-infarct area(P<0.05) . 【Conclusion】 Atorvastatin could ameliorate ventricular remodeling in rats with myocardial infarction, which might be associated with inhibiting the expression of AVP and TGF-β1.
