Objective:To investigate the electron microscopic evaluation results of pre-transplant biopsies of deceased donor kidneys and the corresponding recovery of graft function in recipients after kidney transplantation.Methods:A retrospective analysis was conducted on the clinical data and donor kidney electron microscopy (EM) reports of 196 kidney transplant recipients who underwent pre-implantation kidney biopsies at Renmin Hospital of Wuhan University between October 2020 and June 2023. The ultrastructural pathological features assessed in the pre-transplant kidney biopsy included: the number of glomeruli, the presence of leukocytes and endothelial cells within the glomeruli, the arrangement of capillary loops, abnormalities in podocytes, mesangial cells, mesangial matrix and glomerular basement membrane (GBM), and multilayering of the peritubular capillary basement membrane. Referring to the Mayo Clinic/Renal Pathology Society Consensus Report on the pathological classification, diagnosis, and reporting of glomerulonephritis, the expert consensus on renal biopsy pathology reporting models, and the content of the 2019 Banff Transplant Pathology Meeting, a scoring system was established for ultrastructural pathology of donor kidneys. According to the scores, the recipients were divided into three groups: Group A (total score ≥ 8 points, 94 cases), Group B (total score between 6 and 8 points, 85 cases), and Group C (total score < 6 points, 17 cases). The serum creatinine, estimated glomerular filtration rate (eGFR), and proteinuria at postoperative day 1, day 7, month 1, month 3, month 6, and year 1 were compared among the three groups.Results:Among the 196 donor kidneys, EM examination before transplantation showed the following findings: 19 cases (9.7%) had prominent leukocyte infiltration within the glomeruli, 8 cases (4.1%) had mild leukocyte infiltration, and the remaining 169 cases (86.2%) showed no obvious increase in glomerular leukocytes. Glomerular capillary loop collapse or narrowing was seen in 19 cases (9.7%). Endothelial cell proliferation was observed in 32 cases (16.3%). Homogeneous thickening of the GBM (400-900 nm) was present in 82 cases (41.8%). Foot process effacement ranged from partial to diffuse. Podocyte vacuolar degeneration was seen in 62 cases (32.1%), and podocyte swelling in 10 cases (5.1%). Electron-dense deposits in the mesangial area were observed in 9 cases (4.6%). Mild tubular epithelial swelling was present in 6 cases (3.1%). Only 22 cases (11.2%) showed no multilayering of the peritubular capillary basement membrane, while 174 cases (88.8%) showed 2 to 5 layers of multilayering. All donor glomeruli showed irregular capillary loop arrangement, and the renal interstitium showed scattered inflammatory infiltration and varying degrees of collagen fiber deposition. Group C had significantly higher qualitative proteinuria levels at day 7 and month 1 post-transplantation compared with Groups A and B ( P=0.036, 0.004). There were no statistically significant differences in other renal function indicators among the groups (all P>0.05). Conclusions:Pre-transplant electron microscopy of donor kidneys helps in accurately assessing donor kidney quality and identifying subtle pre-existing pathological changes. It can serve as a reference tool for predicting post-transplant functional recovery. Mild ultrastructural abnormalities in donor kidneys have a relatively controllable impact on long-term graft outcomes.

Objective:To revaluate the systematic reviews/meta-analysis of the literature on acupuncture in the treatment of stroke spastic hemiplegia.Methods:CNKI, Wangfang, VIP, CBM, Cochrane Library, PubMed and Embase were searched for systematic reviews/meta-analyses of acupuncture in the treatment of stroke spastic hemiplegia from the establishment of the databases to July 27, 2022. AMSTAR 2 Scale, Prisma statement (2020) and GRADE system were used to evaluate the quality of the collected literature.Results:A total of 5 systematic reviews/meta-analyses were included, all of which were rated as very low by AMSTAR 2. The 5 studies involved a total of 22 outcome measures, and the GRADE rating results were intermediate evidence in 5, low evidence in 8, and very low evidence in 9.Conclusions:Acupuncture therapy has certain therapeutic effects on reducing the degree of limb spasms and improving limb motor function in patients. However, the methodological quality of the included literature is poor, and there is limited high-level evidence to support conclusions. More high-quality experimental research is still needed to provide strong evidence-based medicine evidence.

Objective To compare the changes of knowledge, attitude and practice (KAP) related to taeniasis and cysticercosis among primary school students before and after health education interventions in disease-elimination pilot areas of Henan Province, so as to evaluate the effectiveness of health education interventions. Methods A primary school was selected from each of Dushu, Bowang and Yangji townships, Fangcheng County, Henan Province from 2017 to 2019; then, 2 to 3 classes were randomly selected from grade 4 to 6 in each primary school, and finally, all students in these classes were enrolled as study subjects. A thematic health education lecture pertaining to taeniasis and cysticercosis was given once each year by means of “health education in class”. The KAP towards taeniasis and cysticercosis was investigated among primary school students using selffilled structured questionnaires, and the changes of awareness of taeniasis and cysticercosis control knowledge and percentage of healthy behaviors formation were compared in primary school students among years and following various frequencies of health education interventions. Results More than 10 thousand person-time primary school students received health education interventions during the period from 2017 to 2019, and a total of 1 223 person-time primary school students were investigated during the 3-year study period, including 633 person-time men and 590 person-time women and 88.55% of primary school students at ages of 10 to 12 years. The proportion of households raising pigs and using dry toiliets decreased from 5.30% (24/453) and 18.10% (82/453) in 2017 to 3.60% (13/361) and 11.08% (40/361) in 2019, respectively. The awareness rate of taeniasis and cysticercosis control knowledge increased significantly from 0.22% (1/453) in 2017 to 62.59% (256/409) in 2018 and 76.73% (277/361) in 2019 (χ² = 567.60, P < 0.001), and the awareness rate was 85.25% (104/122) among primary school students attending the thematic special health education courses for successive three times. The awareness rates of taeniasis and cysticercosis control knowledge were 0.44% (1/225), 58.00% (116/200) and 71.63% (149/208) among male students and 0 (0/338), 66.99% (140/209) and 83.66% (128/153) among female students from 2017 to 2019, and there was a significant difference in the awareness of taeniasis and cysticercosis control knowledge between male and female students in 2019 (χ² = 7.14, P = 0.01). On-site teaching by doctors was the students’ favorite way to receive health education interventions (70.07%, 857/1 223), followed by watching health education videos (58.63%, 717/1 223) and seeing parasite specimens (48.9%, 598/1 223). The proportion of students’ families who used cutting boards for raw and cooked food separately increased from 7.28% (33/453) in 2017 to 47.37% (171/361) in 2019, was 67.21% (82/122) among students attending the health education courses for successive three times. The proportion of students who frequently washed their hands before meals and after using toilet increased from 71.96% (324/453) in 2017 to 89.47% (319/361) in 2019 and was 95.90% (117/122) among students attending the health education courses for successive three times. In addition, the percentage of students washing hands frequently in families using dry toilets was significantly lower in those who did not use dry toilets (χ² = 9.21, P = 0.002), and the proportion of students with a habit of eating raw or undercooked meat decreased significantly from 35.76% (162/453) in 2017 to 6.65% (24/361) in 2019 (χ² = 69.11, P < 0.01). Conclusion The thematic health education activity of “health education in class” contributes greatly to the increase in the awareness of taeniasis and cysticercosis control knowledge and the rate of healthy behaviors formation among primary school students in diseaseelimination pilot areas of Henan Province.

Objective: To investigate the current status of the ten-year implementation of the World Health Organization (WHO) surgical safety checklist (SSC) in China. Methods: A questionnaire was designed based on the three phases described by the checklist — the period before induction of anaesthesia, the period before skin incision, and the period before patient leaves operating room, taking into account some hotspots and disputes.The questionnaire was sent to the members of the Chinese-based online New Youth Anesthesia Forum through the WeChat platform.Answers were completed by mobile phones or desktop computers.Each WeChat ID number allowed only one answer for each individual participant. Results: A total of 3 943 members red the questionnaire invitation, of which 2 121 members completed the questionnaire with an overall completion rate of 53.79%.For checks completed before induction of anesthesia, the percentage of members who routinely practiced checks before induction of anesthesia was 93.35%, the percentage of members who completed each and every element of the checklist was 60.16%, and the percentage of members who selected the element of the checklist the surgeon was not involved in the check was 14.05%.For checks practiced before skin incision, the percentage of members who routinely completed checks before skin incision was 78.22%, the percentage of members who completed each and every element of the checklist was 51.91%, and the percentage of members who selected the element of the checklist surgeons and anesthesiologists routinely stated their own professional key information was 18.24% and 18.81%, respectively.For checks practiced before the patient leaved the operating room, the percentage of members who routinely completed checks before removing the patient from the operating room was 64.26%, and the percentage of members who completed each and every element of the checklist was 44.18%.The percentage of members who was really serious about practicing the checklist was 56.20%.The percentage of members who believed that surgeons should participated in checks practiced before induction of anesthesia was 81.47%.If the member himself or a member of his family needed a surgery, the percentage of members who hoped to implement the checklist was 98.35%.The percentage of members who believed that practicing WHO SSC could reduce the complications of surgery and improve the anesthetic safety of patients was 94.34%. Conclusion The implementing rate of checks practiced before induction of anesthesia is high, while the implementing rates of checks completed before skin incision and before patient leaves operating room are sequentially reduced in China.Although there are some problems with the implementation of WHO SSC, most respondents believe that implementing SSC can improve the anesthetic safety of patients undergoing surgery.

Extracorporeal membrane oxygenation(ECMO) is a type of technique which can be used to replace patients' pulmonary function and cardiac function effectively. Since 2000s,the technique began to apply in pediatric patients but still developed very slowly. As well,patients transport with ECMO is another problem for the pediatricians. So,it is necessary to raise the conception of pediatric ECMO transport network and construction of the network. In this paper,the concept of pediatric ECMO transport network,current status of transport,the characteristics and constitution of pediatric ECMO transport network,indication for transport of pediatric ECMO,the problems in the construction of network were introduced to promote the construction of the network.
