Clinical efficacy of acupuncture combined with extracorporeal shock wave therapy in the treatment of piriformis syndrome / 中国基层医药

Objective:To evaluate the clinical efficacy of acupuncture combined with extracorporeal shock wave therapy in the treatment of piriformis syndrome.Methods:Eighty patients with piriformis syndrome who received treatment in Huaihe Energy Occupational Disease Prevention Hospital Rehabilitation Medicine Center from February 2021 to December 2022 were included in this study. They were divided into a treatment group ( n = 40) and a control group ( n = 40) according to different treatment methods using a retrospective cohort study design. The treatment group was treated with acupuncture combined with extracorporeal shock wave therapy, once every 7 days for 3 consecutive weeks. The control group was treated with extracorporeal shock wave therapy alone once every 7 days for 3 consecutive weeks.Pre- and post-treatment visual analogue scale scores and clinical efficacy were compared between the two groups. Results:There was no significant difference in baseline data between the two groups (all P > 0.05). After treatment, the visual analogue scale score decreased in each group. After adjusting for covariates, there was no significant difference in visual analogue scale score between the two groups ( F = 112.38, P < 0.001). After adjusting the pre-treatment visual analogue scale score, the post-treatment visual analogue scale score in the treatment group was lower than that in the control group [1.417 (95% CI: 1.151-1.683)]. The total response rate in the treatment group was 97.5% (39/40), which was significantly higher than 82.5% (33/40) in the control group ( Z = -2.03, P = 0.042). Conclusion:Acupuncture combined with extracorporeal shock wave therapy is highly effective on piriformis syndrome.

A time series analysis of effects of diurnal temperature range on children with bronchopneumonia in Huzhou, 2014–2019 / 环境与职业医学

Background In the context of global warming, the impact of meteorological factors on human health has gradually become a research hotspot at home and abroad. Objective To describe the distribution of children's bronchopneumonia in Huzhou City, and explore the influence of diurnal temperature range (DTR) on children with bronchopneumonia, so as to provide guidance for identifying vulnerable populations and developing targeted measures. Methods A distributed lag nonlinear model (DLNM) was used to explore the potential nonlinear lag effect of DTR on admission of children with bronchopneumonia in Huzhou City from 2014 to 2019. Then a generalized additive model (GAM) was used to calculate the hospital admission risk of exposure to DTR in total population and sex-, age-, season-stratified populations. Results A total of 17658 hospitalized children with bronchopneumonia were included in the study. When DTR exceeded 7.5 ℃, the relative risk rose abruptly. When DTR reached 17 ℃, the risk of admission to hospital of children with bronchopneumonia was the greatest. In terms of the single-day lag effect, the admission risk of DTR for bronchopneumonia in children began on the same day and persisted until lag day 2; it peaked on the same day, and RR was 1.353 (95%CI: 1.220-1.502). The cumulative lag effect occurred from lag0 to lag0-6, and the highest RR value was at lag0-3, which was 1.938 (95%CI:1.483-2.533). The results of stratified analysis showed that the maximum effect values for boys and girls appeared at lag0-3 (RRboys=2.301, 95%CI: 1.671-3.169) and lag0-2(RRgirls=1.566, 95%CI: 1.152-2.129) respectively, and the effect value and duration of DTR in boys were higher and longer than those in girls. Among different age groups, both children of 0-3 years old and 4-14 years old had the maximum effect value at lag 0-3, the RR values were 1.734 (95%CI: 1.454-2.572) and 1.998 (95%CI: 1.226-2.254) respectively, and the effect value and duration of DTR on the children of 4-14 years old were higher and longer than those of the children of 0-3 years old. As to seasons, no significant increase was found in cumulative effect in summer and autumn (P>0.05); in winter and spring, the maximum effect value appeared at lag0-10, and the RR value was 4.164 (95%CI:1.191-14.561). Conclusion The impact of DTR on bronchopneumonia in children is acute. Boys and children aged 4-14 years old are more sensitive to DTR changes. Therefore, we should be alert to severe DTR changes and take protective measures in advance

Risk assessment of neonatology nosocomial infection based on hazard vulnerability analysis / 中华医院管理杂志

Objective:To assess the nosocomial infection risk events of neonatology experienced by a hospital, for identifying those events deserving high priority in infection prevention and control and critical rooms of improvement, hence minimizing such risks of the hospital.Methods:The hazard vulnerability analysis was called into play, along with literature review and clinical practices, while the hazard vulnerability analysis team of neonatology of the hospital preliminarily screened the indexes in brainstorming method. Then the individual indexes from such screening evaluated by means of questionnaires, and the risk evaluation index system for neonatal infection prevention and control was formed in combination with the risk value evaluation table of Kaiser model. On such basis, an evaluation questionnaire for the prevention and control was developed.In May 2020, the team members scored the possibility and severity of these risk indexes in the form of questionnaire, calculated the hazard risk value, and divided the risk zones by matrix analysis.Results:The risk assessment index system of neonatology was composed of 11 management indexes, 20 implementation indexes and 7 outcome indexes. The top 5 indexes of hazard risk value were: incorrect hand hygiene method(39.20%), inadequate cleaning and disinfection of environmental object surface(39.04%), the formula was not used immediately when ready(38.19%), nosocomial infection outbreak(38.02%), and low hand hygiene compliance(37.99%). The indexes with high severity and low readiness include three indexes related to formula feeding and three indexes related to cleaning and disinfection of object surface. The matrix analysis results showed that there were 9 indexes in the high-risk zone, 7 indexes in the medium risk zone and 22 in the low-risk zone.Conclusions:This study identified risk management events in hospital infection management in neonatology by means of hazard vulnerability analysis. The neonatology administrators are recommended to prioritize indexes in the high risk zone, make a root cause analysis of those indexes of high risk value and low readiness and take intervention measures in time, hence reducing the incidence of nosocomial infection and avoiding the outbreak of nosocomial infection.

Effects of One Finger Massage on Nerve Morphology and Function of Sciatic Nerve Injury Rats / 中国中医药信息杂志

Objective To study the effects of one finger massage on sciatic nerve injury rats. Methods The sciatic nerves were exposed, and the sciatic nerve was held by micro needles to make the sciatic nerve injury model. SD rats were randomly divided into sham-operation group, model group and massage group. In the sham-operation group, the sciatic nerves were exposed but not held. 7 d after the establishment of modeling, rats in massage group received one finger massage for 30 d. After 30 d, SFI and BBB of sciatic nerves were detected. HE staining, transmission electron microscope and immunochemistry assay were used to measure the changes of sciatic nerves. Results Compared with model group, massage group could speed up the recovery of SFI and increase BBB, promote the recovery of sciatic nerve morphology, increased protein level of S-100β, and enhance ultrastructure of newborn nerve growth and recovery. Conclusion One finger massage can effectively promote neurological and functional recovery after sciatic nerve injury in rats.

Unconserved C terminal of pUL76 in human ctomegalovirus elicits aggresome formation / 安徽医科大学学报

Objective To define the nuclear agrresome formation is determinated by which part of the UL76 of HCMV. Full-length, conserved N terminal and unconserved C terminal of pUL76 were constructed to eukaryotic ex-pression plasmid pEGFP-N1 . Methods Primers were designed to amplify full-length and different part of pUL76 according to standard sequence of HCMV AD169 which had been submitted to GenBank(FJ527563. 1). These frag-ments were constructed to eukaryotic expression plasmid pEGFP-N1 . The recombinant plasmids were designated pEGFP-UL76,pEGFP-UL76N, pEGFP-UL76C respectively. Double digestion and sequencing were performed to verify the accuracy of recombinant plasmids construction. Empty vector and three recombinant plasmids were transi-ent transfected to HELF and HepG-2 cells respectively. Reverse transcriptation PCR and Western blot were per-formed to detect the RNA and protein expression level respectively. Different nuclear aggresome formations were visualized with an Olympus fluorescence microscopy. Results pEGFP-N1 and pEGFP-UL76N were unable to in-duce nuclear aggresome formation, whereas pEGFP-UL76 and pEGFP-UL76C were able to elicit nuclear aggresome formation. Conclusion The unconserved C terminal of pUL76 is sufficient to induce nuclear aggresome formation.
