RESUMO
BACKGROUND: Postoperative complications are important factors affecting the survival time and quality of life of patients undergoing radical gastrectomy. AIM: To investigate and compare the anesthetic effects of intravenous general anesthesia combined with epidural anesthesia or ultrasound-guided bilateral transversus abdominal plane block (TAPB) in gastric cancer patients undergoing laparoscopic radical gastrectomy. METHODS: The clinical data of 85 patients who underwent laparoscopic radical gastrectomy in our hospital from December 2020 to January 2023 were retrospectively collected and divided into a TAPB group (n = 45) and epidural anesthesia group (n = 40) according to the different anesthesia and analgesia programs used. The TAPB group received general anesthesia combined with TAPB, and the epidural anesthesia group received general anesthesia combined with epidural anesthesia. The pain status, cognitive status, intestinal barrier indicators, recovery quality, and incidence of complications were compared between the two groups. RESULTS: Compared with the epidural anesthesia group, the TAPB group's visual analog scale scores were significantly lower 6 h, 12 h, 24 h and 48 h after surgery (P < 0.05). The incidence of postoperative cognitive dysfunction (POCD) in the TAPB group was significantly lower than that in the epidural anesthesia group, and the Mini-mental State Examination score 24 h after surgery was significantly higher in the TAPB group than the epidural anesthesia group (P < 0.05). The levels of diamine oxidase and plasma D-lactate were significantly lower in the TAPB group than the epidural anesthesia group 24 h after surgery (P < 0.05). The agitation score and the incidence of agitation during recovery were significantly lower in the TAPB group than epidural anesthesia group (P < 0.05). The total incidence of postoperative complications in the TAPB group was 4.44%, significantly lower than the 20.00% in the epidural anesthesia group (P < 0.05). CONCLUSION: Compared with epidural anesthesia combined with general anesthesia, TAPB combined with general anesthesia had a good analgesic effect in laparoscopic radical gastrectomy and can further reduce the incidence of POCD and postoperative complications, improve the levels of intestinal barrier indicators, and improve postoperative recovery quality.
RESUMO
Objective: To investigate the effect of dexmedetomidine on postoperative cognitive function and delirium in elderly patients undergoing thoracoscopic lobectomy. Methods: 109 elderly patients (age is more than 65 years) who underwent thoracoscopic lobectomy in our hospital from June 2020 to Feb 2022 were randomly divided into the dexmedetomidine (DEX) group (n = 54) and the control group (n = 55). The patients in the experimental group were given dexmedetomidine by intravenous pump, intravenous pump 0.5 µg/kg within 10 minutes, and maintained the speed of 0.5 µg/(kg. h) to 30 min before the operation was ended. The control group was given the same amount of normal saline. Delirium assessment-severity (CAM-S) assessment and Mini-Cog were used to assess the severity levels of POD and POCD 24 h before, 6 hours after, one day after the operation, three days after the operation, and 1 week after the operation. Serum TNF-αα and NSE levels were assessed by using enzyme-linked immunosorbent assay. NRS pain marks were assessed in the DEX group at postanesthesia care unit (PACU) and 24 postoperation. Surgical pierhysmographic index (SPI) evaluation was performed at five time points. Results: The Mini-Cog scores in the DEX group were markedly enhanced compared with those in the saline group 6 and 24 hours after the operation. The SPI values in the DEX group were markedly reduced within 2 min after intubation and at surgical sutures. Moreover, the CAM scores in the DEX group were markedly reduced 24 hours after the operation. Tumor necrosis factor-α (TNF-α) and neuron-specific enolase (NSE) levels were significantly decreased in the DEX group at T1â¼T3. Conclusion: The use of dexmedetomidine in the thoracoscopic lobectomy in elderly patients could reduce the occurrence and severity of postoperative cognitive dysfunction and delirium.
RESUMO
OBJECTIVE: To investigate the incidence and related risk factors of healthy side fracture after hip fracture surgery in the elderly, so as to provide basis for the prevention of re-fracture. METHODS: The data of 452 patients over 65 years old with femoral neck fracture or intertrochanteric fracture treated with hip arthroplasty or proximal femoral intramedullary nailing from June 2012 to June 2017 were analyzed, including 168 males and 284 females, the age ranged from 65 to 97(75.5±7.5) years. There were 191 cases of femoral neck fracture and 261 cases of femoral intertrochanteric fracture. According to whether there was a fracture in the healthy hip after operation, the patients were divided into fracture group and no fracture group. The gender, age, body mass index, fracture type, initial treatment method, bone mineral density, bed time, medical compliance, postoperative short-term delirium, whether there were medical diseases before injury and Harris score of hip joint in the final follow-up were recorded. Univariate Logistic regression analysis was used to screen out the risk factors of healthy side fracture after operation, and then statistically significant risk factors were included in multi factor Logistic regression analysis to screen out the independent risk factors of healthy side fracture after operation of hip fracture in the elderly. RESULTS: Among them, 42 of the 452 patients had hip fractures on the healthy side with an incidence of 9.3%. The average interval between the two fractures was (2.9±2.1) years. Univariate Logistic regression analysis showed that there were significant differences in age, bone mineral density, medical compliance, short-term postoperative deliriun, pre-injury complicated with medical diseases and Harris score of hip joint in the final follow-up (P<0.05). Multivariate Logistic analysis showed that age(OR=4.227), bone mineral density(OR=4.313), combined with medical diseases (OR=5.616) and low hip Harris score at the final follow-up (OR=3.891) were independent risk factors for healthy side fractures after hip fracture surgery in elderly(P<0.05). CONCLUSION: The age, bone mineral density, combined with medical diseases and low Harris score of hip joint in the final follow-up are the main risk factors of healthy side fracture after hip fracture in the elderly. It is necessary to strengthen the treatment of medical diseases, anti osteoporosis and improve hip joint function within 3 years after operation, so as to prevent the occurrence of healthy side hip fracture.

Recent studies have shown that several long noncoding RNAs (lncRNAs) are involved in regulating the immune response to cope with pathogenic invasion. To date, the roles of lncRNAs in the CD4+ T cell response to Treponema pallidum (T. pallidum) infection in neurosyphilis patients remain unknown. The mRNA and lncRNA expression profiles of CD4+ T cells that were isolated from neurosyphilis patients and healthy controls were analyzed by microarray. A total of 2258 lncRNAs and 1728 mRNAs were identified as over-expressed or under-expressed, respectively (fold change > 1.5) in the CD4+ T cells of neurosyphilis patients compared to the healthy controls. The lncRNA-mRNA co-expression network showed that 59 lncRNAs showed significant differences along with significantly different mRNAs. Among the 59 gene pairs, the LOC79999 mRNA was positively correlated with the RP11-160E2.16, RP11-160E2.11, and RP11-160E2.19 lncRNAs, and the NKX1-1 mRNA was positively correlated with the RP11-1398P2.1, RP11-160E2.19, and XLOC_003422 lncRNAs. The following five mRNAs were correlated with two differential lncRNAs: DUSP16, AP000349.1, FAM115C, TIMM8A, and SMCHD1. Gene Ontology (GO) analysis revealed that the differentially expressed coding genes were mainly involved in biological processes and the top 4 terms that associated with above-mentioned differentially expressed coding genes were as follows: defense response to fungus, defense response to bacterium, killing of cells of other organism and disruption of cells of another organism. A subsequent pathway analysis was also conducted, and several pathways, including the T cell receptor, MAPK, and TGF-beta signaling pathways, were associated with the differentially expressed mRNAs. This study reveals the differential expression profiles of lncRNAs in the CD4+ T cell response to the T. pallidum infection in neurosyphilis patients. LncRNAs are involved in key biological processes that comprise the CD4+ T cell response to the T. pallidum infection.
