Objective To investigate the effect of ultrasound-guided anterior quadratus lumborum block at lateral supra-arcuate ligament on postoperative analgesia and inflammation response in elderly patients undergoing robot-assisted laparoscopic radical prostatectomy.Methods A total of 60 elderly patients who had undergone robot-assisted laparoscopic radical prostatectomy from June 2022 to June 2023 were randomly divided into a group of ultra-sound-guided anterior quadratus lumborum block at lateral supra-arcuate ligament combined with general anesthesia(observation group,n = 30)and a general anesthesia group(control group,n = 30).Both groups received patient-controlled intravenous analgesia after surgery.The first compression time of an analgesic pump and the numbers of effective compression and remedial analgesia were recorded.The VAS scores at postsurgical hours 2,12,24,and 48 during rest and coughing were recorded.Interleukin-6(IL-6)and systemic immunoinflammatory index(SII)at one day before surgery and two hours,one day and three days after surgery were recorded.Anal exhaust time,length of postoperative hospital stay and occurrence of adverse reactions were recorded.Results The observation group,as compared with the control group,had significantly longer first compression time of an analgesic pump and had fewer numbers of effective compressions and remedial analgesic administrations(P<0.05).The VAS scores during rest and coughing in the observation group were lower than those in the control group at postsurgical hours 2,12,24,and 48(P<0.05).As compared with one day before surgery,both IL-6 and SII in the two groups increased at 2 hours,1,and 3 days after surgery,but the changes in the observation group were lower than those in the control group(P<0.05).As compared with the control group,the observation group had shorter anal exhaust time and length of postoperative hospital stay,and a lower incidence of adverse reactions(P<0.05).Conclusions Ultrasound-guided anterior quadratus lumborum block at lateral supra-arcuate ligament can provide better postoperative analgesia,reduce inflammatory response and accelerate postoperative recovery in elderly patients undergoing robot-assisted laparoscopic radical prostatectomy.

Objective:To evaluate the effect of anterior quadratus lumborum block at the lateral supra-arcuate ligament on the postoperative pulmonary function in patients undergoing robot-assisted laparoscopic radical prostatectomy under general anesthesia.Methods:Seventy-two American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ patients, aged 50-80 yr, with body mass index of 18.5-27.9 kg/m 2, scheduled for elective robot-assisted laparoscopic radical prostatectomy under general anesthesia, were divided into 2 groups ( n=36 each) using a random number table method: control group and observation group. After induction of general anesthesia, observation group underwent anterior quadratus lumborum block at the lateral supra-arcuate ligament under ultrasound guidance, with 20 ml of 0.375% ropivacaine administered on each side. Control group only received total intravenous anesthesia. Postoperative analgesia was provided by patient-controlled intravenous analgesia until 48 h after operation, and intravenous dezocine was administered as rescue analgesic when the visual analogue scale score at rest≥4. Pulmonary function was assessed at 1 day before surgery and 1-7 days after surgery. Forced vital capacity (FVC), forced expiratory volume in 1 s (FEV 1), maximal mid-expiratory flow rate (FEF 25%-75%), and time to recovery of 80% predicted pulmonary function were recorded. Arterial blood gas analysis was performed at 1 day before surgery and 1-3 days after surgery, and SpO 2, PaO 2 and PaCO 2 were recorded. The consumption of intraoperative remifentanil, effective pressing times of patient-controlled analgesia, and the number of patients required rescue analgesia were recorded. Postoperative pulmonary complications within 7 days after operation and re-hospitalization within 30 days were recorded. The time to first flatus, postoperative length of hospital stay and occurrence of adverse reactions (dizziness, nausea, vomiting) within 3 days after surgery were also recorded. Results:Compared with control group, FVC, FEV 1 and FEF 25%-75% were significantly increased postoperatively, the time to recovery of 80% FVC, FEV 1 and FEF 25%-75% was shortened, postoperative SpO 2 and PaO 2 were increased, postoperative PaCO 2 was decreased, the consumption of intraoperative remifentanil, effective pressing times of patient-controlled analgesia, and the number of patients required rescue analgesia were reduced, the postoperative time to first flatus and length of hospital stay were shortened, and the incidence of adverse reactions and pulmonary complications was decreased ( P<0.05). Conclusions:Anterior quadratus lumborum block at the lateral supra-arcuate ligament can improve postoperative pulmonary function, reduce adverse reactions, and promote early recovery for the patients undergoing robot-assisted laparoscopic radical prostatectomy under general anesthesia.

Objective:To understand the symptoms of diarrhea of residents in Tianjin and their willingness to vaccinate, to provide reference for health education, prevention and control of infectious diarrhea.Methods:Cross-sectional study design was adopted. From September to December 2023, a questionnaire survey was conducted among some residents as subjects in Nankai District, Beichen District, Baodi District and Binhai Area of Tianjin by multistage stratified cluster random sampling,to collect information such as sociodemographic characteristics, diarrhea symptoms and vaccination intention. According to the formula n=[ u2απ (1 - π)]/ δ2, the estimated sample size was 3 458 cases. The logistic regression model was used to analyze the factors related to the willingness of the respondents to receive diarrhea vaccination. The software SPSS 24.0 was used for statistical analysis. Results:A total of 3 808 subjects were investigated, with the male-to-female ratio as 1∶1.11 (1 806∶2 002), the age was (42.48±21.59) years old, and the education level of middle school or below accounted for 50.84% (1 936/3 808). The incidence rate of diarrhea was 18.28% (696/3 808), and 48.84% (1 860/3 808) were willing to be vaccinated with diarrhea vaccine. The results of multivariate logistic regression analysis showed that the age was 15-59 years old and ≥60 years old (a OR=2.31, 95% CI:1.80-2.96; a OR=1.66, 95% CI:1.38-2.00), lived in Binhai Area (a OR=2.09, 95% CI:1.62-2.71), and those who knew that community health service centers can provide the vaccination (a OR=1.61,95% CI:1.34-1.92), those who walked from the address to the community health service center were less than 15 minutes (a OR=1.54, 95% CI:1.28-1.85), those who often travel or on business (a OR=1.36, 95% CI:1.07-1.73), and those who actively obtained health care information related to diarrhea prevention when going abroad (a OR=1.69,95% CI:1.43-1.98) were more willing to be vaccinated against diarrhea. Conclusions:The incidence of diarrhea symptoms of residents was slightly higher in Tianjin, but they were less willing to be vaccinated against diarrhea. People who often go outside and go abroad were more willing to be vaccinated against diarrhea. It is suggested that the popular science propaganda and health education of diarrhea vaccine should be effectively carried out by using network platform in community.

Osteonecrosis of the femoral head (ONFH) is one of the common and difficult-to-treat orthopedic diseases caused by a variety of factors that lead to abnormal blood flow to the femoral head, which in turn leads to deformation and collapse of the femoral head and eventually results in severe hip joint dysfunction. The key to the treatment is early diagnosis and correct treatment according to the stage classification and active prevention of further aggravation of ONFH aiming to delay or avoid hip replacement surgery in young and middle-aged patients. At present, there are various non-surgical and surgical hip-preserving modalities for early ONFH, designed to slow down the progression of the disease, prevent the femoral head from collapsing and stop the mild collapse. In recent years, with the emergence and development of bone reconstruction biomaterials, artificial bone reconstruction after scraping of ONFH lesions has shown great potential in the treatment of early ONFH. The authors review the research progress in hip-preserving modalities for early ONFH in young and middle-aged patients from non-surgical and surgical perspectives, hoping to provide a reference for clinical treatment of early ONFH.

Objective:To summarize the experience of transthoracic epicardial insertion pacemaker for isolated congenital third-degree atrioventricular block (CAVB), and explore the necessity and feasibility of permanent pacemaker in the treatment of CAVB in neonates and infants.Methods:The clinical data and follow-up of four children with CAVB admitted to the Senior Department of Pediatrics, the Seventh Medical Center of PLA General Hospital from September 2010 to February 2022 were analyzed retrospectively.Two patients were implanted with permanent cardiac pacemakers during an early stage (less than one year old), and two patients were implanted during the non-early stage (one year old and above). All patients were diagnosed based on clinical symptoms, electrocardiogram and echocardiographic examination.After treatment, the pacing threshold, atrial sensing function, clinical symptoms, electrocardiogram and echocardiography examination of four patients were followed up.Results:All patients were successfully implanted with permanent cardiac pacemakers.One patient of non-early implantation was died of severe pneumonia and sepsis.During the follow-up period, pacing threshold, amplitude, impedance, minute ventilation and sensor function indicated pacemakers worked well in other three patients.Heart rates in these patients were significantly recovered, and showed growth trends in line with percentile curves for Chinese children and good movement skills.Conclusion:A pacemaker implantation performed by an experienced operator is a safe and feasible treatment for children with CAVB diagnosed in neonates and infants period with good prognosis.

Objective:To investigate the changes of ocular surface microbiota in obese patients before and after dietary intervention.Methods:From November 1, 2020 to May 1, 2021, 35 obese patients in the obesity management center of the Department of Endocrinology and Metabolic Diseases of Henan Provincial People′s Hospital were selected for a 4-week low-calorie dietary intervention of 1 600-1 800 kcal/day. The body weight, body mass index(BMI), body composition(body fat, body fat percentage, visceral fat grade, total body water, and skeletal muscle) were observed before and after dietary intervention. The characteristics of ocular surface flora in obese patients before and after intervention were analyzed by 16S rRNA sequencing.Results:The body weight, BMI, body fat, percentage of body fat, visceral fat grade and total body water decreased significantly after 4 weeks( P<0.05), while there was no significant difference in skeletal muscle( P>0.05). There was no significant difference of ocular surface flora α and β in diversity( P>0.05). Opportunistic pathogens Pseudomonas and Cutibacterium decreased significantly, while Faecalibacterium, Lachnospiraceae NK4A136 group, Oscillospiraceae UCG 002, and Blautia, which producing short chain fatty acids, increased significantly( P<0.05). Functional prediction analysis showed that the metabolic pathways such as degradation related pathways and insulin signaling pathways of volatile organic compounds(VOCs) were significantly enriched. Conclusion:After dietary intervention, opportunistic pathogenic bacteria decreased and short chain fatty acid producing bacteria increased in obese patients. The altered ocular surface flora may be related to the degradation of VOCs and the improvement of insulin sensitivity.

Hypoxia is a common feature of solid tumors. As transcription factors, hypoxia-inducible factors (HIFs) are the master regulators of the hypoxic microenvironment; their target genes function in tumorigenesis and tumor development. Intriguingly, both yes-associated protein (YAP) and its paralog transcriptional coactivator with a PDZ-binding motif (TAZ) play fundamental roles in the malignant progression of hypoxic tumors. As downstream effectors of the mammalian Hippo pathway, YAP and/or TAZ (YAP/TAZ) are phosphorylated and sequestered in the cytoplasm by the large tumor suppressor kinase 1/2 (LATS1/2)-MOB kinase activator 1 (MOB1) complex, which restricts the transcriptional activity of YAP/TAZ. However, dephosphorylated YAP/TAZ have the ability to translocate to the nucleus where they induce transcription of target genes, most of which are closely related to cancer. Herein we review the tumor-related signaling crosstalk between YAP/TAZ and hypoxia, describe current agents and therapeutic strategies targeting the hypoxia-YAP/TAZ axis, and highlight questions that might have a potential impact in the future.

Objective:To systematically evaluate the effect of glucagon-like peptide 1 receptor agonists(GLP-1RA)on the brain structure of rat or mouse Alzheimer’s disease(AD)models.Methods:Data of randomized controlled trials from January 2000 to January 2018 for the effect of GLP-1RA on the brain structure of AD rats or mice were searched from all databases, including the Cochrane Library, EMbase, PubMed, Chinese Journal Full-text Database, the Chinese biomedical literature database, Chinese PSTP VIP and Wanfang database.Literature was selected based on inclusion and exclusion criteria defined in advance, and the quality was evaluated using the SYRCLE as animal experimental bias risk assessment tools.Valid data were retrieved and a meta-analysis was performed using the RevMan 5.3software.Results:A total of 9 articles with 207 rats and mice were included.Among the 207 cases, 123cases were in the experimental group and 84 cases in the control group.After treatment with GLP-1RA, there were significant differences in the amyloid plaque load[Low dose group: mean difference(MD)=-5.55, 95% CI: -6.92 to-4.17, P<0.01, High dose group: MD=-4.81, 95% CI: -6.63to-2.98, P<0.01], the amount of p-tau protein(MD=-3.16, 95% CI: -4.29 to-2.02, P<0.01), and the activation of microglia in rat or mouse brain(liraglutide treatment group: MD=-7.85, 95% CI: -12.66 to-3.04, P<0.01, lixisenatide treatment group: MD=-7.60, 95% CI: -9.56 to-5.65, P<0.01)between the treatment group and the control group. Conclusions:GLP-1RA can reduce the amyloid plaque load, decrease the number of neurofibrillary tangles and inhibit the activation of microglia in the rat or mouse brain.

Objective: evaluate the efficacy of a single medial locking plate and lag screws based on computer-assisted pre-operation plan (CAPP) for the treatment of pilon fractures. Methods: Between 2013 and 2016, data of 27 patients with pilon fractures who were treated using a single medial locking and lag screws based on CAPP were retrospectively analyzed. All the cas-es were AO/OTA 43-C type pilon fractures. According to the Rüedi-Allgöwer classification, there were 5 cases of type Ⅱ and 22 cases of type Ⅲ. Among 27 patients, 19 patients had fibula fracture. CAPP was performed for all fractures, including simulated re-duction, virtual surgery, and implantation of internal fixation. The time of CAPP, intraoperative realization of preoperative plan, op-eration time, intraoperative blood loss, and pre- and post-operative range of motion of ankle were recorded. Functional outcomes at final follow up were assessed using American Orthopedic Foot and Ankle Society (AOFAS) ankle hindfoot scale, visual analogue scale (VAS). Results: The mean time of CAPP was 25.8 minutes (range, 14-30 minutes). The average operating time was 138.5 minutes. The average intraoperative blood loss was 225.9 ml. All the twenty-seven patients were followed up for an average period of 18.6 months. The average AOFAS score, VAS score at the final follow-up was 82.9, 2.7 points respectively, which was signifi-cantly improved compared with those before operation (t=-19.358, 7.720; all P< 0.001). Conclusion CAPP system is convenient and efficient, which can facilitate the treatment of type C pilon fractures with a single medial locking plate and lag screws. In addi-tion, satisfactory clinical outcomes can be obtained.
