ABSTRACT

Objective:To observe the clinical efficacy of Yishen Tongluofang in treating oligosperm type male infertility with kidney deficiency and blood stasis syndrome and explore its effect on serum sex hormones and seminal plasma microenviro. Method:One hundred and four patients were randomly divided into observation group and control group with 52 cases each. Patients in control group took compound Xuanju capsules orally, 3 capsules/time, 3 times/day. Patients in observation group took Yishen Tongluofang, 1 dose/day. Treatment courses continued three months and followed up for three months in both groups. The pregnancy situations of spouses within six months were recorded. Examination of semen parameters before and after treatment and score of kidney deficiency and blood stasis syndrome were conducted. The levels of seminal plasma zinc, fructose, elastase, acid phosphatase and <italic>α</italic>-glucosidase, serum follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRT) and testosterone (T) were detected before and after treatment. Result:During the observation period of six months, the pregnancy rate of spouses in the observation group was 22.00%, higher than 10.00% in the control group, but the difference was not statistically significant (<italic>χ</italic><sup>2</sup>=2.678,<italic>P</italic>>0.05). The clinical efficacy in the observation group was better than that of the control group (<italic>Z</italic>=2.326,<italic>P</italic><0.01). Sperm concentration, sperm motility, sperm motility, normal morphological sperm and linear movement speed of the observation group were all superior to those of the control group<italic> </italic>(<italic>P</italic><0.01). The levels of zinc and fructose in seminal plasma of the observation group were higher than those of the control group (<italic>P</italic><0.01), and the score of kidney deficiency and blood stasis syndrome was lower than that of the control group (<italic>P</italic><0.01). Serum FSH, LH and PRT levels in the observation group were lower than those in the control group (<italic>P</italic><0.01), and the T level was higher than that in the control group (<italic>P</italic><0.01). The seminal plasma elastase of the observation group was lower than that of the control group, while the levels of acid phosphatase and <italic>α</italic>-glucosidase were higher than those of the control group (<italic>P</italic><0.01).

ABSTRACT

Objective:To observe the effect of forsythiaside A on gastrointestinal motility disorder induced by chemotherapy in mice, and explore the mechanism of forsythiaside A regulating gastrointestinal motility. Method:The 60 KM mice were randomly divided into normal group, model group, metoclopramide group (5 mg·kg-1) and forsythiaside A low, medium and high-dose groups (30, 60, 120 mg·kg-1), 10 for each group, which include half male and half female. The above dose was given once a day for 4 consecutive days, which the intragastric volume was 10 mL·kg-1. One hour after 1rd day administration, equal volume of saline was intraperitoneally injected to the normal group, 2 mg·kg-1 cisplatin was intraperitoneally injected to the other groups with daily for 4 consecutive days. Observing the effects of forsythiaside A on gastric emptying and small intestinal propulsion on mice models, serum gastrin (GAS) and somatostatin (SS), motilin (MTL), vasoactive intestinal peptide (VIP) levels were examined by enzyme-linked immunosorbent assay (ELISA). Activities of acetylcholinesterase (AChE) and total nitric oxide synthase (tNOS) in gastric antrum and ileum were detected by ELISA. The expression of AChE and inducible nitric oxide synthase (iNOS) in gastric antrum and ileum were detected by Western blot. Result:Compared with normal group, the gastric retention rate and small intestinal propulsion rate of the model group were significantly increased (P<0.01), serum levels of MTL, GAS, SS and VIP, the AChE activity in the homogenate of ileum in the model group were significantly reduced (P<0.05,P<0.01), while the tNOS activities in gastric antrum and ileum were significantly increased (P<0.05,P<0.01). Protein expression of AChE in gastric antrum and ileum were significantly decreased (P<0.05), and the expression level of iNOS protein was significantly increased in the model group (P<0.05). Compared with model group, different doses of forsythiaside A can reduce the gastric residual rate and small intestinal propulsion rate of mice to varying degrees. Meanwhile forsythiaside A can increase the serum levels of MTL, GAS, SS, and VIP, and the AChE activity and protein expression levels in gastric antrum and ileum tissues were also increased, while tNOS activity and iNOS protein expression were decreased in gastric antrum and ileum (P<0.05,P<0.01). Conclusion:Forsythiaside A can significantly ameliorate the delayed gastric emptying and small intestine hyperfunction induced by cisplatin in mice. Its mechanism to ameliorate gastrointestinal dysfunction caused by chemotherapy is related to the regulation of gastrointestinal AChE and NOS activity in gastric antrum and ileum and the regulation of gastrointestinal hormone levels.

ABSTRACT

Purpose@#Multiple pathways are involved in inducing liver fibrosis, which can damage the integrity of liver. Among them, miR-125b has been found to exert an activating action on hepatic stellate cells. Endoplasmic reticulum stress and autophagy lead to liver disorders. Here, we evaluated the therapeutic influence of miR-125b on the endoplasmic reticulum function in injured livers submitted to bile duct ligation. @*Materials and Methods@#For inducing injury, bile duct ligation was done on miR-125b transgenic rats (miR-125b-Tg) in wild type rats. The rat T-6 cells received transfection of miR-125b mimic and Tunicamycin. Protein expressions were observed by western blot analysis. @*Results@#Compared to wild type rats, liver-injured rats showed significant impairment of liver function as assessed by the total bilirubin levels. The miR-125b-Tg rats showed decrease in activity of aspartate transaminase and alanine transaminase. Liver tissues of miR-125b-Tg rats showed weaker fibrotic matrix formation. Upregulation of miR-125b decreased the bile duct ligation-mediated hepatic disturbances for the expressions of endoplasmic reticulum kinase, inositol-requiring kinase 1alpha, sXBP1, CHOP, LC3, p62, ULK, and caspase-3/-8/-9. T-6 cells transfected with miR-125b mimic and treated with Tunicamycin caused decrease in levels of cleaved caspase-3, sXBP1, CHOP, and LC3. The miR-125b signaling showed protective effect on the liver tissues subjected to injury and fibrosis histopathology. @*Conclusion@#This study demonstrates a novel insight into the miR125b-mediated stabilization of endoplasmic reticulum integrity, which slows the progression of injury-induced hepatic deterioration.

ABSTRACT

OBJECTIVE: To explore the mediating effect of the general self-efficacy(GSE), stress coping personality(SCP) and perceived professional benefits(PPB) among nursing practice students. METHODS: A total of 836 nursing interns from six grade A hospitals in six cities were selected as the research subjects using convenience sampling method. The GSE, SCP and PPB were investigated by the General Self-Efficacy Scale, Scale of Stress Coping Personality for College Students and Questionnaire of Nurses Perceived Professional Benefit. RESULTS: The average scores of GSE, SCP, and PPB were(24.6±5.8),(183.1±28.7) and(139.5±18.0), respectively. The scores of GSE and SCP were positively correlated with that of PPB [correlation coefficients(r) were 0.31 and 0.38 respectively, both P<0.01], and a positive correlation was found between GSE and SCP(r=0.41, P<0.01). The hierarchical regression results showed that the sense of control, tenacity and tolerance of SCP of the interns had a predictive effect on their PPB(all P<0.05); but the effect of SCP on PPB was weakened after inclusion of GSE(P<0.01). The structural equation model analysis results showed that both SCP and GSE of interns had a direct positive predictive effect on PPB(all P<0.01), GSE played a partial mediating role between SCP and PPB, accounting for 20.3% of the total effect. CONCLUSION: The SCP of nursing interns can directly or indirectly affect their PPB, and GSE plays a partial mediating effect between SCP and PPB.

ABSTRACT

OBJECTIVE: To compare the applicability of three risk assessment methods on occupational health risk assessment of chemical harmful factors in a resin anchorage production workshop. METHODS: A resin anchoring agent production workshop was selected as the research subject using the judgment sampling method. Contact ratio assessment method and comprehensive index method(both are semi-quantitative evaluation method) and qualitative risk assessment method were applied to estimate the occupational health risks of jobs involved with styrene, dibutyl phthalate and phthalic anhydride. The assessment was carried out, and the obtained risk level was standardized as the risk ratio. The evaluation results of these three methods were compared. RESULTS: The assessment results of exposure ratio method were 1-3, and those of comprehensive index method were 2-3. The risk ratio of the above methods after standardization is consistent with that before standardization. The result of qualitative risk assessment was 2-3, and the risk ratio after standardization was 3-4. The risk ratio after standardization was 1 level higher than that before standardization. Kappa analysis results showed that the result of contact ratio method and the comprehensive index method was in good agreement(Kappa=0.53, P<0.05). The qualitative risk assessment method was inconsistent with the contact ratio method and the comprehensive index method(Kappa values were 0.19 and 0.40, both P<0.05). CONCLUSION: Comprehensive index method is the preferred method for occupational health risk assessment of anchorage agent production workshop under the condition that detection results of occupational hazards can be obtained. Qualitative risk assessment method can be used when the test results cannot be obtained.

ABSTRACT

Guided by cell-based anti-anaphylactic assay, eighteen cage-like monoterpenoid glycosides (1-18) were obtained from the bioactive fraction of P. lactiflora extract. Among these, compounds 1, 5, 6, 11, 12, 15, and 17 significantly reduced the release rate of β-HEX and HIS without or with less cytotoxicity. Furthermore, the most potent inhibitor benzoylpaeoniflorin (5) was selected as the prioritized compound for the study of action of mechanism, and its anti-anaphylactic activity was medicated by dual-inhibiting HDC and MAPK signal pathway. Moreover, molecular docking simulation explained that benzoylpaeoniflorin (5) blocked the conversion of L-histidine to HIS by occupying the HDC active site. Finally, in vivo on PCA using BALB/c mice, benzoylpaeoniflorin (5) suppressed the IgE-mediated PCA reaction in antigen-challenged mice. These findings indicated that cage-like monoterpenoid glycosides, especially benzoylpaeoniflorin (5), mainly contribute to the anti-anaphylactic activity of P. lactiflora by dual-inhibiting HDC and MAPK signal pathway. Therefore, benzoylpaeoniflorin (5) may be considered as a novel drug candidate for the treatment of anaphylactic diseases.

ABSTRACT

Objective: To explore the effect of moxibustion at Shenque (CV 8) on myocardial structure and function in exercise-induced fatigue rats. Methods: A 12-week treadmill running training was performed to create an exercise-induced fatigue rat model. Sixty eligible male specific-pathogen-free grade Sprague-Dawley rats were randomly divided into a blank group, a control group, a model group, a non-meridian non-acupoint group, a Zusanli (ST 36) group and a Shenque (CV 8) group, with 10 rats in each group. Rats in the blank group did not receive treadmill running training or moxibustion. Rats in the control group did not receive treadmill running training but received mild moxibustion at Shenque (CV 8). Rats in the model group received treadmill running training but no moxibustion. Rats in the non-meridian non-acupoint group, the Zusanli (ST 36) group and the Shenque (CV 8) group received moxibustion at the non-meridian non-acupoint points, Zusanli (ST 36) or Shenque (CV 8) immediately after each treadmill running training, 15 min each time, once a day for 5 consecutive days a week at a 2-day interval, 60 times of moxibustion in total. Left ventricular end-diastolic diameter (LVEDd), left ventricular end-systolic diameter (LVESd), left ventricular diastolic volume (LVDv), left ventricular systolic volume (LVSv), ejection fraction (EF), stroke volume (SV), early diastolic peak flow velocity of mitral valve (E) and late diastolic peak flow velocity of mitral valve (A) of each group before and after the last treadmill running training were measured. Blood was collected 6 h after the last treadmill running training, and serum C-reactive protein (CRP), myoglobin (Mb), creatine kinase-myocardial band (CK-MB), cardiac troponin I (cTnI) and cardiac troponin T (cTnT) levels were detected. Finally, the heart was separated, the heart mass (HM) was measured, the cTnT level of the myocardial tissue was detected, the ultrastructural changes of the left ventricular myocardium were observed by transmission electron microscope, the left ventricular fraction shortening (LVFS), E/A and heart mass index (HMI) were calculated. Results: Compared with the same group before treatment, the rat cardiac LVEDd, LVESd, LVDv, LVSv, SV, E and A were significantly increased (all P<0.01), and the rat LVFS, E/A and EF were significantly decreased (all P<0.01) in the model group and the non-meridian non-acupoint group after treatment; the rat cardiac SV, LVDv, LVSv, E and A were all increased (all P<0.01), while E/A and EF were decreased (all P<0.01) in the Zusanli (ST 36) group after treatment; the rat cardiac LVDv, E and A were significantly increased (P<0.01 or P<0.05), and E/A was significantly decreased (P<0.01) in the Shenque (CV 8) group after treatment. After treatment, compared with the blank group, the rat cardiac LVEDd, LVESd, SV, LVDv, LVSv, E, A, the serum CRP, Mb, CK-MB, cTnI, cTnT and HMI, and the myocardial cTnT were increased (all P<0.01), and the LVFS, E/A and EF were all reduced (all P<0.01) in the model group; compared with the model group and the non-meridian non-acupoint group, rats in the Zusanli (ST 36) group and the Shenque (CV 8) group showed decreased LVEDd, LVESd, SV, LVDv, LVSv, E, A, serum CRP, Mb, CK-MB, cTnI, cTnT and HMI, and myocardial cTnT (P<0.01 or P<0.05), along with increased LVFS, E/A and EF (all P<0.01); compared with the Zusanli (ST 36) group, Mb and A of the Shenque (CV 8) group were decreased (both P<0.01), while both E/A and EF were increased (P<0.01, P<0.05). Transmission electron microscopy examination showed that myofibrils in the blank group and the control group were neatly arranged with clear light and dark bands; the model group and the non-meridian non-acupoint group showed different degrees of myofibril disintegration and breakage, increased and aggregated mitochondria of different sizes, and increased electron density. The myofibrils in the Shenque (CV 8) group and Zusanli (ST 36) group were arranged neatly with clear light and dark bands, and compensatory hyperplasia of mitochondria. Conclusion: Moxibustion at Shenque (CV 8) and Zusanli (ST 36) both can effectively improve the occurrence of myocardial remodeling in exercise-induced fatigue rats, and the effect of moxibustion at Shenque (CV 8) is better in improving cardiac function.

ABSTRACT

Objective: To observe the therapeutic effect of mild moxibustion on irritable bowel syndrome (IBS) visceral hyperalgesiamodel rats and its regulatory effect on P2X3 receptors in the spinal cord, anterior cingutate cortex (ACC) and thalamic ventral posterolateral nucleus (VPL). Methods: Thirty 8-day-old newborn rats were randomly divided into a normal group (n=6) and a modeling group (n=24) according to the completely random number table method. Rats in the normal group were bred routinely, and those in the modeling group were subjected to preparing IBS chronic visceral hyperalgesia model using colorectal distention (CRD) in stimulation method. Rats successfully modelled were re-divided into a model group, a mild moxibustion group, a P2X3 receptor antagonist group, and a normal saline group according to the completely random number table method with 6 rats in each group. Rats in each group received corresponding interventions from the 37-day old, once a day for 7 consecutive days. Immunohistochemistry and Western blot assays were used to detect P2X3 protein expressions in the spinal cord, ACC and VPL of rats. Results: Under different intensities of CRD stimulation, the abdominal withdrawal reflex (AWR) scores of the model group were significantly increased versus the normal group (all P<0.05); the AWR scores of the mild moxibustion group and the P2X3 receptor antagonist group were significantly reduced versus the model group (all P<0.01). The P2X3 protein expressions in rat spinal cord, ACC and VPL tissues of the model group were significantly increased versus the normal group (all P<0.01); the P2X3 protein expressions in rat spinal cord, ACC and VPL tissues of the mild moxibustion group and the P2X3 receptor antagonist group were significantly reduced versus the model group (all P<0.01). Conclusion: Mild moxibustion can inhibit the P2X3 receptor expressions in the spinal cord, ACC, and VPL tissues of IBS visceral hyperalgesia model rats, which may be the mechanism of mild moxibustion in relieving the central sensitization of rats with IBS visceral hyperalgesia.

ABSTRACT

Objective:To investigate the ability of the anti-PD-1(scFv)/hIL-15 fusion protein(PD-15) to specifically bind to PD-1 in vitro and the effect of the combination of PD-15 with GF-hIL-15Ra-K562(G15Ra-K562) feeder cells to expand NK/T cells. Methods:Overlap PCR was used to construct G15Ra expression vector. pMXs-G15Ra-IP was transfected into K562 by electroporation. G15Ra-K562 feeder cell lines were obtained by limiting dilution method. pUC57-PD-15 was constructed by digestion and ligation. Lipofectamine? 2000 was used to transiently transfect pUC57-PD-15 into HEK293T cells and the conditioned medium containing PD-15 fusion protein was obtained. Density gradient centrifugation was used to obtain human peripheral blood mononuclear lymphocytes(PBMC), and CFSE staining was used to mark active proliferating cells. Flow cytometry was used to detect the ability of PD-15 to specifically bind to PD-1 and its effect on the proliferation of human PBMC and the proportion of different subpopulations of lymphocytes.Results:The feeder cells G15Ra-K562 with high expression of fusion protein G15Ra was successfully constructed. The addition of hIL-15 can increase the ability of G15Ra-K562 to expand human PBMC by more than 5 times( P<0.05). PD-15 fusion protein has PD-1 specific binding ability( P<0.001), combined with G15Ra-K562 can efficiently expand human peripheral blood-derived NK/T cells in vitro( P<0.05). The cells expanded by PD-15 and G15Ra-K562 are mainly natural killing cell, CD8 + T and CD4 + T cells. Conclusions:The PD-15 fusion protein can specifically target the PD-1 molecule and has a strong human peripheral blood-derived NK/T cell expansion ability when combined with G15Ra-K562 feeder cells. These results shed light on selective expansion of PD-1 + lymphocytes in vitro.

ABSTRACT

BACKGROUND@#Delivery room resuscitation assists preterm infants, especially extremely preterm infants (EPI) and extremely low birth weight infants (ELBWI), in breathing support, while it potentially exerts a negative impact on the lungs and outcomes of preterm infants. This study aimed to assess delivery room resuscitation and discharge outcomes of EPI and ELBWI in China.@*METHODS@#The clinical data of EPI (gestational age [GA] <28 weeks) and ELBWI (birth weight [BW] <1000 g), admitted within 72 h of birth in 33 neonatal intensive care units from five provinces and cities in North China between 2017 and 2018, were analyzed. The primary outcomes were delivery room resuscitation and risk factors for delivery room intubation (DRI). The secondary outcomes were survival rates, incidence of bronchopulmonary dysplasia (BPD), and risk factors for BPD.@*RESULTS@#A cohort of 952 preterm infants were enrolled. The incidence of DRI, chest compressions, and administration of epinephrine was 55.9% (532/952), 12.5% (119/952), and 7.0% (67/952), respectively. Multivariate analysis revealed that the risk factors for DRI were GA <28 weeks (odds ratio [OR], 3.147; 95% confidence interval [CI], 2.082-4.755), BW <1000 g (OR, 2.240; 95% CI, 1.606-3.125), and antepartum infection (OR, 1.429; 95% CI, 1.044-1.956). The survival rate was 65.9% (627/952) and was dependent on GA. The rate of BPD was 29.3% (181/627). Multivariate analysis showed that the risk factors for BPD were male (OR, 1.603; 95% CI, 1.061-2.424), DRI (OR, 2.094; 95% CI, 1.328-3.303), respiratory distress syndrome exposed to ≥2 doses of pulmonary surfactants (PS; OR, 2.700; 95% CI, 1.679-4.343), and mechanical ventilation ≥7 days (OR, 4.358; 95% CI, 2.777-6.837). However, a larger BW (OR, 0.998; 95% CI, 0.996-0.999), antenatal steroid (OR, 0.577; 95% CI, 0.379-0.880), and PS use in the delivery room (OR, 0.273; 95% CI, 0.160-0.467) were preventive factors for BPD (all P < 0.05).@*CONCLUSION@#Improving delivery room resuscitation and management of respiratory complications are imperative during early management of the health of EPI and ELBWI.

ABSTRACT

Objective:To analyze the epidemiological characteristics of outbreak of infectious diseases reported in schools in Shanghai from 2014 to 2019, and to suggest related strategies for efficient response to public health emergencies. Methods:Descriptive epidemiology method was used to analyze the outbreak of infectious diseases reported in schools in Shanghai from 2014 to 2019. Results:A total of 82 infectious disease emergencies were reported in schools in Shanghai during 2014 and 2019, involving 1 760 disease cases and 2 deaths. The incidence peaks in each year were from March to June and from September to December. The events mainly occurred in kindergartens and primary schools, with 35 and 25 incidences respectively. The main types of events were hand-foot-and-mouth disease and chickenpox, accounting for 48.78% and 46.34% of public health emergencies of infectious diseases in school, respectively. The time it took to report the events was positively correlated to the duration and the scale of the events. The sooner the epidemic was reported, the shorter it lasted. Conclusion:The kindergartens and primary schools are the places with a high incidence of infectious diseases reported in schools. Measures such as regular surveillance, vaccination management, early reporting and effective handling should be executed at the early stage so as to prevent the spread of the epidemics.

ABSTRACT

Objective:Using a spatio-temporal clustering analysis of varicella in Shanghai from 2006 to 2015 at a subdistrict level, we aim to provide decision support for formulating a reasonable varicella prevention strategy. Methods:Based on the data of varicella cases in Shanghai from 2006 to 2015, SaTScan was employed to detect and analyze the spatial pattern of varicella clusters. Moreover, field investigation was combined to infer and explain the risk factors of varicella clusters. Results:The spread of varicella in Shanghai from 2006 to 2015 had an obvious annual change and spatial differentiation at a subdistrict level. The findings of SaTScan showed that with a confidence level of 99.9%, there were totally 7 spatio-temporal clustering events in Shanghai from 2006 to 2015, in which 3 events were regional events and 4 were independent events. Independent events usually lasted for 2-4 years, while regional events in the "Jiading-Chongming district" and "Songjiang-Minhang district" areas had a longer duration and a larger impact. Conclusions:From 2006 to 2015, there is an obvious temporal and spatial clustering pattern of varicella in Shanghai. Majority of abnormal spatio-temporal clusters occur in rural areas rather than urban areas, which may be related to increasing floating population and migration of susceptible population caused by the implementation of large-scale construction projects.

ABSTRACT

Objective:To explore CT and MRI features of the endolymphatic sac tumor (ELST).Methods:The CT and MRI morphology confirmed by surgical pathology for 19 patients with ELST were retrospectively analyzed from June 2011 to May 2019 in Eye & ENT Hospital of Fudan University. The features of CT and MRI included location, size, adjacent structures invasion, CT values, bone destruction, features of T 1WI and T 2WI, enhancement distribution characteristics, dynamic enhancement curve morphology, DWI signal characteristics. The ADC values of the lesions and ipsilateral medial pterygoid muscles were compared using a paired t test. Results:Nineteen ELST patients (one with bilateral diseases) were included. Totally 20 ears (right 9 and left 11) of 13 females and 6 males were studied. The masses with slightly high-density and obscure boundary were located around the vestibular aqueduct at the posterior edge of the petrosal bone. Bone destruction involved mastoid process of the middle ear (16 ears), jugular foramen (11 ears), semicircular canal (10 ears), facial nerve canal (7 ears) and internal auditory canal (9 ears). A large amount of residual bone could be found in the interior of nineteen masses. The CT value was (78.6±21.9) HU. The lesion showed central iso-intensity and peripheral hyperintensity on T 1WI and T 2WI in 16 ears, while no obvious hyperintensity on T 1WI in the other 4 ears. The hyperintensity on T 1WI was around the margin of the lesion in 10 ears, situated at lateral side in 5 ears and all over the lesion in 1 ear. Flow voids signals could be seen in 9 ears as well. Liquid-liquid plane was seen on T 2WI in 2 ears. The solid mass portion which showed iso-intensity on both T 1WI and T 2WI presented marked enhancement on contrast-enhanced T 1WI, while other part of the mass no enhancement. DWI of 14 ears illustrates no evidence of restricted diffusion, and the ADC value [(1.25±0.08)×10 -3 mm 2/s] was slightly higher than that of the medial pterygoid muscles ( t=4.437, P=0.001). The style of time-signal intensity curves of the dynamic contrast-enhanced MRI was rapidly ascending followed by descending curves in 2 ears. Conclusion:Imaging findings of ELST have some characteristics, including located around the vestibular aqueduct at the posterior edge of the petrosal bone, bone destruction, peripheral hyperintensity on T 1WI and no restricted diffusion, which is helpful for its diagnosis.

ABSTRACT

Objective:To analyze the clinical characteristics of acute drug poisoning, and provide better management for poisoned patients in Emergency Department.Methods:We retrospectively enrolled 197 patients diagnosed as acute drug poisoning in Emergency Department of Beijing Chaoyang Hospital from January 1, 2019 to December 31, 2019. Medical records included age, gender, baseline diseases, medication time, visit time, kinds of drugs, drug concentrations, accompanying symptom, hospitalization duration, treatment, fluid resuscitation and outcomes. The inclusion criteria were as follows: age≥ 14 years old, and met the criteria of acute poisoning. The exclusion criteria were as follows: age<14 years old; incomplete clinical data; pesticide poisoning; toxic gas poisoning; and other non-drug poisoning. All patients were divided into the survival group and death group according to their outcomes at the discharge. Clinical characteristics, laboratory parameters and treatments were compared using the Student’s t test, Mann-Whitney U test, as appropriate. Results:The mean age of all the patients was 38.9±20.4 years. The majority were young patients, accounting for 134 cases (68.0%). The accompanying symptoms included consciousness disturbance (106 cases), dizziness (56 cases), fatigue (38 cases), and nausea and/or vomiting (42 cases). The duration of medication-to-visit time was 0.5-96 h, with an average of 7.17±0.89 h. The types of drugs included 105 (53.2%) sedatives and hypnotics, 73 antipsychotics (37.1%), 17 antibiotics (8.6%), and 20 antipyretic analgesics (10.2%). The Glasgow comascale (GCS) score of patients in the survival group was higher than that of the death group (12.47±3.05 vs 7.60±4.43, P<0.01). In the death group, the alanine aminotransferase, urea nitrogen, creatinine, cardiac troponin I, prothrombin time, activated partial thromboplastin time, plasma fibrinogen and D-dimer were higher than those of the survival group (all P<0.05). One hundred and eighty-seven patients were cured, while 10 patients died. One hundred and fifty-nine patients were treated with gastric lavage, and 23 patients were treated with blood purification. The concentrations of toxic drugs before and after treatment in 134 poisoned patients were compared. The concentration of drugs after treatment was significantly lower than that before treatment. Conclusions:Acute non-pesticide poisoning in Emergency Department is mainly caused by sedatives, hypnotics, antipsychotics, and antipyretics and analgesics. It is important to conduct laboratory examinations for toxic medications to provide better management for poisoned patients. It is necessary to establish a standardized monitoring system and management path for acute drug poisoning.

ABSTRACT

Objective:To assess the biosafety risk from a public health perspective and provide scientific evidence for centers for disease control and prevention to formulate diversified strategies and well-organized resource allocation. Methods:Based on the global summary of pathogenic microorganism which might be used against human beings intentionally, we performed a multi-round consultation to the expert team with a scientific background and professional qualification, using a Delphi method. According to the consultation and reliability test, a consistent evaluation was conducted from seven dimensions, including fatality rate, implementation of biosafety-related events, short-term probability, long-term probability, difficulty of rescue, early detection, and response capacity of the public health system. Results:The overall opinions of the experts tended to be consistent. Bacillus anthracis had been scored the highest in the comprehensive biosafety risk, which was much higher than the second (botulinum toxin) and third places (Yersinia pestis), raising a significant public health concern. In addition, multiple hemorrhagic fever viruses had a higher biosafety risk. Conclusions:Based on the perspective of public health, the biosafety risk can be evaluated reasonably. Pathogenic microorganisms with zoonotic characteristics and long incubation periods are more difficult to detect in advance in the environment, posing a higher risk. The formulation of disease control and prevention strategies in public health resource-limited areas warrants particular attention to high-risk biosafety events.
