Objective:To investigate the clinical application of multimodal low-opioid combined with saphenous nerve block analgesia in elderly patients undergoing knee arthroplasty.Methods:This study is a randomized controlled study.A total of 60 elderly patients who underwent elective knee arthroplasty in the Department of Orthopedics, the First Hospital of Shanxi Medical University from January 2021 to December 2021 were selected and divided into 2 groups by numerical randomization: mode low opioid analgesia regimen group(observation group)and traditional analgesia regimen group(control group), 30 cases in each group.Observation group: (1)Preemptive analgesia: Oral celecoxib 200 mg, qd.from 3 days before surgery, the mini-mental state examination(MMSE)score was used to evaluate the cognitive function; (2)Intraoperative analgesia: After the prosthesis was installed, choose to inject analgesics around the knee joint(ropivacaine 200 mg, morphine 5 mg, epinephrine 0.25 mg, dexamethasone 5 mg/100 ml normal saline, also known as "cocktail" solution); (3)Postoperative analgesia: After the operation, continuous saphenous nerve block(0.2% ropivacaine, 2 ml/h)was performed under ultrasound guidance, and the dose of nerve block was adjusted according to the degree of rehabilitation training.Control group: no special treatment before and during the operation, traditional postoperative patient-controlled intravenous analgesia(PCIA)was used after the operation, the formula WAs as follows: sufentanil(2 μg/kg)+ flurbiprofen axetil(200-300 mg)+ Tropisetron(5-10 mg). The numerical rating scale(NRS)scores were observed and recorded 1 day before surgery, 6, 12, 24, and 48 hours after surgery; the time of the first active straight leg raising after surgery, the time of landing; the range of motion(ROM)of the knee joint 3, 7, and 14 days after surgery; the American Hospital for Special Surgery Knee Score(HSS)at 14 days, 1, 3, and 6 months after surgery; serum substance P(SP)and interleukin-6(IL-6)concentrations 1 day before surgery and 48 hours after surgery, and adverse events were recorded.Results:Compared with the control group, the patients in the observation group had lower NRS scores at 6, 12, 24, and 48 hours after the operation( t=27.705, 27.532, 21.739, 25.780, all P<0.05); the first active straight leg raising time and the time of landing earlier after the operation, and the knee joint at 3, 7, and 14 days after the operation, the range of motion(ROM)was better( t=35.496, 43.716, 3.766, 5.216, 6.009, all P<0.05). And the American hospital for special surgery knee score(HSS)was higher at 14 days, 1 month, and 3 months after surgery( t=19.247, 32.337, 22.651, all P<0.05), but there was no significant difference at 6 months after surgery.Simultaneously, the serum SP and IL-6 concentrations in the observation group 48 h after the operation were (431.0±11.3)ng/L and(11.9±2.7)ng/L, respectively.Compared with the control group(442.5±15.6)ng/L, (14.4±2.9)ng/L( t=5.362, 4.144, both P<0.05). Compared with the control group, which were lower than those in the incidence of postoperative nausea and vomiting was lower, the length of hospital stay was shorter in the observation group( χ2=4.630, t=3.311, P=0.031, 0.002), and the other indicators had no statistical differences(all P>0.05). Conclusions:Multimodal low-opioid combined with saphenous nerve block analgesia can significantly reduce perioperative pain in elderly patients undergoing knee arthroplasty, improve early postoperative mobility, and speed up postoperative functional recovery.

Objective To analyze the death status of children ≤ 5 years old in Jiaxing City from 2013 to 2017,and to provide scientific and effective measures of decreasing the children mortality and ensuring the health of children.Methods Death surveillance data of children ≤5 years old was obtained from monitoring network covering the whole city of maternal and child health information systems and the relevant maternal and child health statistics.The mortality rate,the sequence and changing trend of main death causes,prenatal health services of children ≤5 years old in Jiaxing City from 2013 to 2017were analyzed.Results From 2013 to 2017,there were 2 788 cases death of children ≤5 years old in Jiaxing City.The neonatal mortality rate (NMR),infant mortality rate (IMR),≤5 years old children mortality rate(U5MR) in Jiaxing City were 2.33‰,3.52‰ and 4.83 ‰,respectively.The mortality rates of all ages showed a declining trend year by year (x2NMR =19.641,P<0.001;x2IMR =31.705,P <0.001;x2U5MR =48.294,P <0.001).There were significant differences in the mortality between the lower local and the migrant children (x22013 =26.16,x22014 =18.45,x22015 =27.72,x22016 =14.49,x22017=24.19;P<0.001).The top two causes of death in children ≤ 5 years old were drowning,premature birth and low birth weight.The top two causes of death in infants and newborns were premature birth,low birth weight and other congenital anomalies.In the recent five years,49.60% of children ≤5 years old died in the hospital.At the same time,the proportion of deaths on the way and at home was 15.64% and 34.76% respectively.Although there was a gap in the level of prenatal health services between local and mobile children,the gap has been declining year by year.Conclusions The key measures to decrease the mortality rate of children under 5 years old in Jiaxing City include strengthening the management of pregnancy care and high-risk pregnancy;paying attention to tertiary prevention and doing a good job in monitoring birth defects such as prenatal screening;enhancing safety education and child supervision for parents of children in 1-4 years old;reinforcing the construction of maternal and child health professional team and the technical training of newborn resuscitation techniques such as neonatal asphyxia recovery technology;intensifying the health-care and management of migrant children and improving the ability of parents to utilize child medical service.

Rift Valley fever (RVF) is an acute, febrile zoonotic disease that is caused by the RVF virus (RVFV). RVF is mainly prevalent on the Arabian Peninsula, the African continent, and several islands in the Indian Ocean near southeast Africa. RVFV has been classified by the World Organisation for Animal Health (OIE) as a category A pathogen. To avoid biological safety concerns associated with use of the pathogen in RVFV neutralization assays, the present study investigated and established an RVFV pseudovirus-based neutralization assay. This study used the human immunodeficiency virus (HIV) lentiviral packaging system and RVFV structural proteins to successfully construct RVFV pseudoviruses. Electron microscopy observation and western blotting indicated that the size, structure, and shape of the packaged pseudoviruses were notably similar to those of HIV lentiviral vectors. Infection inhibition assay results showed that an antibody against RVFV inhibited the infective ability of the RVFV pseudoviruses, and an antibody neutralization assay for RVFV detection was then established. This study has successfully established a neutralization assay based on RVFV pseudoviruses and demonstrated that this method can be used to effectively evaluate antibody neutralization.

OBJECTIVE: To examine the level of occupational exposure to whole body vibration( WBV) in a hydroelectric power station,and evaluate its effects on workers' health. METHODS: A hydroelectric power station in Hangzhou City was chosen as study subject by using judgment sampling method. The level of WBV exposure to workers and high vibration level areas were measured,and the vibration frequency was analyzed. The comfort and allowing duration of occupational exposure in WBV exposed workers was evaluated. RESULTS: The median root-mean-square of accelerometer acceleration of WBV exposure in generator floor,turbines-floor,middle-floor,hydraulic floor of the hydroelectric power station were 0. 894,0. 995,1. 095 and 0. 904 m/s~2,respectively. The central frequency of WBV in this station was 1. 25 Hz. Among the 105 monitoring spots,8. 6% of WBV exposed workers of the spots did not perceive or feel uncomfortable,but 91. 4%of them felt uncomfortable or very uncomfortable. Only 12. 4% of the WBV exposed workers tolerated more than 8 hours of WBV occupational exposure. CONCLUSION: There is an occupational hazard of WBV in this hydroelectric power station.The low frequency vibration with central frequency below 1. 25 Hz is the key control point of the WBV of this hydroelectric power station.
