Nipah virus(NipahVirus,NiV)is a zoonotic virus that can cause encephalitis and severe respiratory symptoms in humans and animals,and is at risk of being introduced into China.At present,there are many factors related to the transmission of Nipah virus disease(NVD),but the actual effects of these factors are controversial.Therefore,with the help of meta-analysis,this paper aims to determine the current mortality and the main means of transmission of NVD,so as to pro-vide reference for the input of controlling Nipah virus disease and making emergency plans for pre-vention and control in our country.By searching the articles published in Pubmed,Embase,Web of knowledge,CNKI,VIP Chinese Sci-tech Journals Database and Wanfang Database up to December 31,2022,the literature of cross-sectional,cohort and case-control studies with NiV encephalitis fa-tality rate(CFR)and risk factors were selected.Results showed that a total of 25 literatures were included in the meta-analysis after retrieval and screening,and the fatality rate of NiV encephalitis was 64.6％(95％CI,60.8-68.2;I2=96.8％).Subgroup analysis showed that tree climbing(OR=1.43;95％CI:1.05-1.96),bats were seen near their nighttime residence(OR=2.38;95％CI:1.74-3.25)and direct contact with date palm SAP(OR=6.01;95％CI:4.07-8.89)Bananas(OR=2.25;95％CI:1.31-3.85)OR porcine(OR=11.87;95％CI:1.15-122.23)was significantly associated with NiV encephalitis.The results of this study suggest that NiV encephalitis has a high mortality rate,and tree climbing,nocturnal exposure to bats,and exposure to pig,banana,and date palm SAP increase the risk of NiV encephalitis.In order to prevent NiV transmission,epidemic surveillance,education and publicity should be strengthened and protective measures should be taken.

Organ transplantation is an effective treatment for end-stage organ failure. However, organ shortage has always been a common problem faced by countries around the world. The recognition and active participation of intensive care unit (ICU) medical staff in organ donation contributes to promoting the development of organ donation, thereby alleviating the shortage of donor organ. In this article, the key strategies of ICU donor management to promote organ donation and the key strategies of ICU medical staff management to promote organ donation were summarized, aiming to provide reference for organ donation practitioners (especially ICU medical staff) and jointly facilitate the professional development of organ donation.

Objective:To investigate the clinicopathological characteristics and metastatic risk factors for patients with lymph node metastasis in central region of differentiated thyroid cancer, and to provide a basis for clinical treatment.Methods:A total of 200 patients with differentiated thyroid cancer from January 2017 to October 2018 in Jiangmen Central Hospital of Guangdong Province were selected. According to the central lymph node metastasis, the patients were divided into metastasis group and non-metastasis group. The clinicopathological features of the two groups were compared, including gender, age, tumor diameter, lesion gland lobe, the number of tumors, TNM staging, capsular infiltration, thyroid stimulating hormone (TSH), anti-thyroglobulin antibody (TG-Ab), operation mode, blood flow grading, microcalcification, thyroid peroxidase antibody (TPO-Ab) and pathological type. The relationship between central lymph node metastasis and clinical characteristics was analyzed. The risk factors of central lymph node metastasis were analyzed by using logistic regression model.Results:Of the 200 patients, 52 (26.00%) patients had central region lymph node metastasis and 148 (74.00%) patients had no central region lymph node metastasis. The tumor diameter ≥ 2 cm, capsule infiltration, microcalcification and grade Ⅲ blood flow in the metastasis group were all higher than those in the non-metastasis group, and the differences were statistically significant [86.5% (45/52) vs. 68.2% (101/148), 40.4% (21/52) vs. 16.9% (25/148), 34.6% (18/52) vs. 11.5% (17/148), 23.1% (12/52) vs. 7.4% (11/148), all P < 0.05]. There were no statistically differences in the proportion of patients stratified by other clinicopathological factors (all P > 0.05). Logistic regression model suggested that tumor diameter ≥ 2 cm ( OR = 1.424, 95% CI 1.041-1.948, P = 0.009), capsular infiltration ( OR = 3.541, 95% CI 1.378-9.099, P = 0.009), microcalcification ( OR = 4.058, 95% CI 1.693-9.727, P = 0.002) and grade Ⅲ of blood flow ( OR = 5.174, 95% CI 2.148-12.463, P < 0.01) were independent risk factors for lymph node metastasis in central region. Conclusion:Central lymph node metastasis in patients with differentiated thyroid cancer is related to tumor diameter, capsular infiltration, microcalcification and grade Ⅲ of blood flow, which should be paid more attention in clinic.

Objective To observe the effect of Yiaikang capsules on viral load, immunologic function and quality of life of patients with human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS). Methods A prospective randomized controlled clinical study was conducted, 118 patients with HIV/AIDS admitted to Department of Integrated Traditional Chinese and Western Medicine of Qinghai Fourth People's Hospital from July 2015 to February 2017 were enrolled, and they were divided into two groups by random digital table method, 59 cases in each group. The control group received highly active anti-retroviral therapy (HAART); while the treatment in combined Chinese and western medicine group was additionally given Yiaikang capsules on the basis of the therapy in control group, 5 capsules (0.5 g per grain,) once and 3 times a day for 12 months. The differences of World Health Organization HIV quality of life scale (WHOQOL HIV-BREF) score, CD4+, CD8+T-lymphocyte and viral load levels were compared between the two groups. Results After treatment for 12 months, the results of WHOQOL HIV-BREF scores in two groups were reduced significantly compared with those before treatment (P ＜ 0.05), and the degree of decrease of WHOQOL HIV-BREF score in combined Chinese and western medicine group was slower than that in control group (82.57±8.76 vs. 70.53±9.45, P ＜ 0.05). The CD4+, CD8+levels in control group after treatment were of no significant change compared with those before treatment (P ＞ 0.05), but the viral load level was decreased significantly after treatment compared with that before treatment (log/mL: 3.57±0.82 vs. 3.89±1.32, P ＜ 0.05); the CD4+in combined Chinese and western medicine group after treatment was obviously higher compared with that before treatment (number/μL: 413.67±187.39 vs. 376.65±206.51), the viral load level was markedly lowered compared with that before treatment (log/mL: 3.14±0.76 vs. 3.81±1.27) and the level of CD4+was significantly higher in combined Chinese and western medicine group than that in control group (413.67±187.39 vs. 382.72±194.82), viral load level in combined Chinese and western medicine group was siginificantly lower that in the control group (3.14±0.76 vs. 3.57±0.82, P ＜ 0.05), but the number of CD8+in two groups after treatment was of no significant change (P ＞ 0.05). Conclusion Yiaikang capsules possibly may elevate the number of CD4+T-lymphocytes and decrease the level of viral load to improve the quality of life in patients with HIV/AIDS.

Objective To investigate the role and significance of neuropilin-2(NRP2)for regulating the angiogenesis of pancreatic neuroendocrine tumors(PNETs).Methods The NRP2 expression in pancreatic neuroendocrine tumer BON-1 cell line was intevened.The BON-1 cells cultural supernatants in the control group and interference group were used to treat human umbilical vein endothelial cells(HUVEC).CCK-8 was used to detect the cell proliferation,Transwell was used to detected the cell migration and the tubule formation test was used detect the pro-angiogenesis.Results The CCK-8 detection showed that there was no statistically significant difference in the supernatant treated HUVEC proliferations between the interference group and control group medium(P>0.05):the absorbancy in the control group was 0.35±0.04,while which in the interference group was 0.32±0.04.The Transwell test showed that the invasion ability of HUVEC treated with cultural supernatants in the interference group was weakened compared with the control group,the control group was(203±13)/hole,while the interference group was(100±10)/hole(P＜0.01);the tubule formation test showed that HUVEC tubular formation treated by cultural supernatant in the interference group was decreased,the control group was 40±5,while the interference group was 24±3(P＜0.01).Conclusion Interfering NRP2 expression of BON-1 cells can inhibit the vessel formation ability of co-cultured HUVEC,suggesting that NRP2 may have the pro-angiogenesis effect of PNETs,and may be a potential new target for the treatment of PNETs.

Objective To analyze the abnormal detectable rates of different kinds of blood test indexes before and after treatment in the patients with snake bite and to probe into the change condition of these indexes after different snake bite .Methods The inpa‐tients with clearly diagnosed what kind of snake bite in the past two years were selected as the research subjects .The multiple blood test indexes were determined before and after treatment in these patients .The abnormal detectable rates of these indexes were ana‐lyzed and compared among various snake bite patients .Results The different kinds of snake bite all could cause the different de‐grees of changes in some detection indexes among partial patients .Specially ,the detectable rates of WBC ,PT ,APTT ,TT ,D‐D ,CK , CK‐MB ,LDH ,Urea ,Cr and Cys‐C increase and PLT and Fbg decrease caused by viper bite were apparently higher than those caused by other kinds of snake bites (P<0 .05) .The detectable rates of CO2 increase and K+ decrease in the coral snake bite were apparently higher than those in trimeresurus gramineus ,cobra and viper bite (P<0 .05) .Conclusion Because the snake species and toxicities are different in the various snake bites ,so the caused changes and the abnormal detectable rates of blood test indexes also are different .

Objective To assess the safety and efficacy of stent-assisted coil embolization for acutely ruptured wide-necked intracranial aneurysms. Methods We retrospectively reviewed 192 wide-necked intracranial aneurysms in 178 patients. The efficacy and peri-procedure complications of stent-assisted embolization were compared between rup?ture aneurysms and unrupture aneurysms. Results Stent was successfully implanted in 78 rupture aneurysms and 114 un?rupture aneurysms. There was statistically significant difference between rupture aneurysms and unrupture aneurysms groups in rate of poor prognosis on discharge ( 23.1%vs. 5%,χ2=12.726, P<0.001) but not in the peri-procedure compli?cations rate (14.1%vs. 6.1%,χ2=3.456,P>0.05)nor in the rate of mortality and permanent disability (8.9%vs. 6.1%,χ2=0.475, P>0.05). Angiograms at 14.7 months of follow-up did not reveal any significant difference between rupture aneu?rysms and unrupture aneurysms groups in aneurysm complete occlusion (74.1%vs. 70.6%,χ2=0.197,P>0.05), recana?lization (10.3%vs. 9.4%,χ2=0.034,P>0.05)and in-stent stenosis (3.4%vs. 4.7%,χ2=0.136,P>0.05). Conclusion Stent-assisted coil embolization for acutely rupture wide-necked intracranial aneurysms can prevent recurrence effective?ly and can achieve high complete occlusion rate in long term follow-up. However, its procedure related complications and mortality is higher in rupture aneurysms than in unrupture aneurysms, which indicates that a caution is needed to conduct stent-assisted coil embolization in rupture aneurysms.

Objective To explore the change regulation of blood coagulation function before and after treatment of snake bite pa‐tients .Methods A total of 226 hospitalized patients with clear diagnosis belong to what kind of snakes in the past two years were selected in this study ,39 cases were bit by coral ,76 cases were bit by trimeresurus stejnegeri ,47 cases were bit by cobra ,24 cases bit by king cobra ,40 cases were bit by adder .Five blood coagulation indexes were determined before and after treatment various pe‐riods for these patients .The tested results were made to statistical analysis according to kind of snakes ,periods and disease condi‐tion .Results D‐D level obvious .rise before treatment for the severe cases patients of coral snake bite (P<0 .05) .Plasma prothrom‐bin time (PT) ,activated partial clotting enzyme live time (APTT) ,thrombin time (TT)and D‐D level rise and Fib level reduced be‐fore treatment for the severe cases patients of trimeresurus stejnegeri bite ,and Fib and D‐D level before and after treatment had sta‐tistical significant difference with the mild patients (P<0 .05) .Every index for the cobra and king cobra had no statistical signifi‐cant differences (P>0 .05) before and after treatment ,only D‐D level of the severe cases had statistical significance before treat‐ment in contrast to the mild cases of cobra bite (P< 0 .05) .The changes of 5 item blood coagulation indexes were all very large whether mild or severe for viper bite patients ,a number of comparisons had statistical significance difference (P<0 .05) whether before or after treatment and whether mild or severe for viper bite patients .Conclusion The bite of coral snake ,cobra and king co‐bra affect little for the blood coagulation function .The severe cases patients of trimeresurus stejnegeri bite might lead to more seri‐ous blood coagulation function abnormality but the recovery is faster after treatment .The viper bite might lead to maximum blood coagulation function abnormality and the recovery is slow after treatment .
