Objective To explore the therapeutic effects and the possible defense mechanisms of Shenmai injection on acute lung injury.Methods SD rats were randomly divided into three groups:the control group(NS),the oleic acid group(OA)and the Shenmai injection group(SM).The modal of acute lung injury in rat(OA group and SM group)were induced by receiveing 0.1ml/kg oleic acid injection into tail vein,and NS group were injected 0.9% sodium chloride 0.1ml/kg.After in jecting loeic acid SM group were injected with Shenmai injection by 2ml each one.The expression of ICAM-1 was examined meanwhile examining breath frequency,wet/dry weight ratio,artery blood oxygen each group of rats,the histopathologieal change of lung tissue was observed.Results The W/D ratio,polymorphonuclear(PMN)infiltration,the lung interstitial edema,the extent of pulmonary alvedus wall destroys and the ICAM-1 expression in lung tissue of OA group increasingly increased compared with NS group,and SM group significantly decreased compared with OA group.Also along with time extending,the ICAM-1 expression of OA group devates gradually,while SM group does not change significantly.The arterial partial pressure of oxygen in group OA significantly decreased compared with NS group,while SM group increased compared with OA group.The microscope demonstrated that the extent of lung injury of OA group was more serious than that of NS group,while OA group was milder than OA group.Conclusion Shenmai injection can lighten oleic acid induced acute lung iniury,and cut down the expression of ICAM-1 in lung tissue.So it has a certain function to the early the acute lung injury.

Objective Through epidemiological analysis of prehospital trauma care in Guangzhou during 1996～2004,to explore common characteristics and trends of it.Methods The data of the prehospital trauma patient were collected by Guangzhou First Aid Service Command Center from 1996 to 2004 and was prospectively analyzed. Results The number of prehospital care had been increased year by year(increased by 3.56 times in the nine years).The number of the trauma patients had been increased by 7.98 times.Head injury was in the first place(6.86%). Most of casualties fell into the age of 21～40 years old.The male patients were the two times that of female patients.Conclusion Trauma has become an serious problem. The improvement of prehospital emergency network, ability of on-the-spot emergency care and popularizing the knowledge of emergency are key to reduce the casualties.

Objective To determine the random spot albuminuria to creatinine ratio (ACR) of normal pregnant women , to track the pregnancy outcome , and to discuss the predictive value of ACR in women with hy-pertensive disorders complicating pregnancy (HDCP). Methods Except for 87 pregnant women suffering from HDCP, 2 038 pregnant women were enrolled in this study. ACR, routine examinations of blood and urine, blood biochemical, 24-hr urinary protein were determined. Results ACR, but not 24-hr urinary protein level,was sig-nificantly higher in women with HDCP. There was positive correlation between the ACR and 24-hr urinary protein quantitation. Age, gestational weeks, ACR, red blood cells, fasting plasma glucose, serum creatinine, total pro-tein were the independent risk factors for HDCP. The sensitivity , specificity and optimal cut off value of ACR for predicting HDCP were 0.78, 0.63, 1.46 mg/mmol. Conclusions There was positive correlation between ACR and 24-hr urinary protein quantitation , and ACR provided a more sensitive pathway for early predictionof HDCP.

Objective To investigate the effects of Delta-opioid receptor activator DADLE on the expression of the p38 MAPK and the neuronal apoptosis after global cerebral ischemia-reperfusion and explore the neuroprotective mechanisms of DADLE.Methods Global cerebral ischmemia-reperfusion models in rats were induced by bilateral common carotid artery occlusion combined with hypotension.Rats were randomly divided into sham group (n=10),ischemia-reperfusion group(n=10) and three treatment groups with different doses of DADLE (2 mg group,3 mg group,5 mg group,n=10).TUNEL method and Western blot analysis were used to measure apoptotic neurons and expression levels of p38 MAPK phosphorylation,repectively.Results DADLE treatment significantly reduced neuron apoptosis (P＜0.05).The expression levels of p38 MAPK were increased in ischemia-reperfusion group than in sham group (P＜ 0.05).In DADLE treated groups,the expression levels of p38 MAPK were dose-dependently decreased compared with the ischemia-reperfusion group.Conclusion Delta-opioid receptor activator DADLE can be neuroprotective against global I/R injury.Attenuation of apoptosis and p38 MAPK signal pathway might be involved in the neuroprotective mechanism of DADLE.

Objective To investigate the incidence of enteric pathogens causing acute gastroenteritis (AGE) among children to measure the incidence of coinfections,and to compare the clinical characteristics of those infected with one versus multiple agents.Methods A retrospective study was conducted from January 2014 to December 2014.All patients between 1 month and 14 years of age admitted to the Pediatric department with a diagnosis of AGE were eligible for enrollment.Two stool samples for each patient were tested for gastrointestinal pathogens.We summarized the clinical severity of episodes,describing the duration of diarrhea,duration and frequency of vomiting,fever.All patients underwent medical evaluation with estimation of dehydration.Results One or more etiological agents were detected in 3595 out of 4728 patients(76.0％),while we did not detect any etiological agent in 1133 (24.0％).Rotavirus was detected in 1889 (40.0％),adenovirus in 412 (8.7 ％),norovirus in 309 (6.5 ％),verotoxigenic Escherichia coli (VTEC) in 274 (5.8 ％),Salmonella spp.in 276(5.8％),Klebsiella pneumoniae in 123 (2.6％),Shigella spp.in 78 (1.6％),Staphylococcus aureus in 70 (1.5％),C.perfringens in 126(2.7％).In 1370 children out of 4728(29.0％),we found evidence of coinfection.with rotavirus and norovirus was the most common 150 (3.2％),rotavirus and C.perfringens was also common 127(2.7％).Children with coinfection had a more severe clinical presentation.The difference has statistical significance.Conclusion Rotavirus is still the most common pathogen in children with acute diarrhea,followed by NV,adenovirus,Salmonella spp.and VTEC.Rotavirus with norovirus infection was the most common.VTEC combined with three kinds of virus infection had the highest incidence.Children with multiple viral infections were more severe than those of single virus infection in the duration of vomiting and dehydration.There was no significant difference in the duration of fever and diarrhea and the frequency of diarrhea.Children infected by viruses and bacteria had a more severe clinical presentation such as fever,vomiting and diarrhea lasting for a long time,more serious diarrhea and dehydration than those with single bacteria and single virus infection.The difference has no significant difference in degree and duration of diarrhea.

Objective To develop a hospice care attitude scale for medical workers and to test its reliability and validity. Methods The inital scale was formed by literature review, semi-structured interview and expert consultation.

【Objective】 To study how blood donation intention among college students was influenced by publicity information (framework effect), individual characteristic (altruistic personality) and micro-system of the social ecological systems(organization trust) through the viewpoints of social psychology, sociology and behavioral economics, aiming at providing new strategies for donors recruitment in colleges. 【Methods】 A total of 1 225 questionnaires were distributed to four universities in Xiamen and Quanzhou, Fujian Province from June 2021 to December 2021, with blood donation publicity information included, to investigate the blood donation intention, altruistic personality, organization trust and demographic characteristics. 【Results】 A total of 99.18%(1 215/1 225)of the collected questionnaires were valid.The average score of blood donation intention was (76.40 ± 24.31) (the range of value was 0-100). Multiple linear regression showed that altruistic personality and organization trust were positively associated with donation intention (P<0.05). Altruistic personality and organization trust had a significant interaction; with the increase of organization trust, the correlation between altruistic personality and donation intention would decrease (P<0.05). In addition, the publicity information had significant frame effect on blood donation intention when other variables in the regression model were controlled (P<0.05). Compared to the negative framework, the positive framework can promote the donation intention better. 【Conclusion】 When recruiting potential blood donors among college students, positive image of blood centers is conductive to promote organization trust therefore promote donation intention.The effective use of framework effect to boost blood donation intention might improve the efficiency of donor recruitment to a certain extent.

AIM:This study aimed to observe the analgesic effects of Hegu acupoint catgut embedding in a rat model of labor and investigate its influence on biomarkers such as calcitonin gene-related peptide(CGRP)signals at the Hegu acupoint.METHODS:Thirty-six pregnant rats were randomly divided into three groups:control group,Hegu acu-puncture group,and Hegu catgut embedding group.Pain threshold changes were assessed using the tail immersion test and paw withdrawal thermal latency at four time points:pre-induction,before the onset of labor,at the onset of labor,and at the mid-stage of labor.Tissue samples from the Hegu acupoint were collected at the mid-stage of labor to detect the ex-pression of CGRP,substance P(SP),and mast cells using immunofluorescence.The concentrations of ATP and ade-nosine were measured using ELISA.RESULTS:Before labor induction,there was no significant difference in tail immer-sion test and paw withdrawal thermal latency among the three groups(P>0.05).Before the onset of labor,both the acu-puncture and catgut embedding groups exhibited significantly higher tail-flick times and paw withdrawal latencies com-pared to the control group(P<0.05).At labor initiation and mid-labor,the catgut embedding group had significantly higher tail-flick times and paw withdrawal latencies compared to both the control and acupuncture groups(P<0.05).During mid-labor,the expression of CGRP,SP,mast cells,ATP,and adenosine concentrations in the catgut embedding group was significantly higher than that in the control and acupuncture groups(P<0.05),with co-expression of CGRP,SP,and mast cells observed.CONCLUSION:Hegu acupoint catgut embedding effectively alleviates labor pain,and its mechanism may involve increased local expression of CGRP and SP,promoting mast cell degranulation,and increasing ATP release and its conversion to adenosine.

Objective To observe the effects of AnMeiDan(AMD),a representative formula of Peiyuan Guben Tranquilisation method,on the learning memory of zebrafish model of sleep deprivation(SD),and to explore the possible mechanism and the optimal apparent dose based on the Orexin signalling pathway.Methods 120 4-month-old wild-type AB line zebrafish were randomly divided into blank group,model group,AMD low-dose group(0.009 mg·mL-1·d-1),AMD medium-dose group(0.027 mg·mL-1·d-1),AMD high-dose group(0.081 mg·mL-1·d-1),and melatonin group(0.4 mg·mL-1·d-1).Zebrafish SD model was established by LED light induction method,24 h behavioural changes of zebrafish in each group were monitored by zebrafish behavioural tracking system,differences in learning and memory ability of zebrafish in each group were detected by T-maze,the state and number of neurons in the brain of zebrafish in each group were observed by Hematoxylin-Eosin(HE)staining method,the structural changes of neurons in the brain of zebrafish in each group were observed by transmission electron microscopy,and changes in neuron structure in the brain of zebrafish in each group were detected by ELISA method.The levels of Orexin A(OXA)and Orexin B(OXB)in zebrafish were detected by enzyme-linked immunosorbent assay(ELISA),and the protein and mRNA expression levels of OXA/p38 mitogen-activated protein kinase(P38 MAPK)/extracellular regulated protein kinase(ERK1/2)were detected by protein immunoblotting and real-time fluorescence quantitative assay(RT-PCR)in zebrafish.Results Compared with the blank group,the total number of rests,duration and distance were reduced in the model group(P<0.05),and the latency to enter the target region(OR)was prolonged(P<0.01);the number of neuronal cells was reduced,the nuclei were degenerated(P<0.01),cytoplasmic hyalinosis was increased(P<0.01),and light colouring was observed,the nuclei were collapsed,the nuclear membranes were ruptured and lysed,the chromatin was solidified,and the mitochondria were swollen and deformed with internal cavities,and lamellipod-like myelin-like structure was formed;the brain tissue OXA,OXA,and ERK1/2 expression levels of the mRNAs and the mRNAs of these signaling pathways were increased(P<0.01).brain tissue OXA and OXB proteins were significantly elevated,OXA mRNA and protein were significantly up-regulated,and P38 MAPK and ERK1/2 mRNA and protein were significantly down-regulated(P<0.01).Compared with the model group,the drug intervention could prolong the total resting exercise time of SD zebrafish(P<0.05);shorten the latency of zebrafish to reach OR(P<0.05);protect the structure and morphology of neuronal cells,and alleviate the damage of brain tissues;reduce the content of OXA and OXB in the brain tissues(P<0.01);and down-regulate the expression of OXA mRNA and protein(P<0.01),and up-regulate the P38 MAPK and ERK1/2 mRNA and protein expression of P38 MAPK and ERK1/2(P<0.01);and the quantity-effect relationship was obvious,and the effect of high dose of AMD was optimal.Conclusion AMD can improve the learning and memory ability in zebrafish SD model,and its mechanism may be related to the regulation of OXA/P38 MAPK/ERK1/2 signalling pathway and alleviation of neuronal damage in the brain,and the high dose group of AMD showed the best effect.
