Objective To investigate the effect of pneumoperitoneum pressure during robotic-assisted kidney transplantation (RAKT) on the function of the transplant kidney. Methods The data of 243 kidney transplant recipients were retrospectively analyzed and divided into open kidney transplantation (OKT) group (n=105) and RAKT group (n=138). The RAKT group was further divided into 13 mmHg group (n=67) and 7 mmHg group (n=71) based on pneumoperitoneum pressure. The donor information, recipient's preoperative general data, intraoperative data, and postoperative recovery of the three groups were compared. In the RAKT group, the renal artery, segmental artery, interlobar artery, and venous flow velocity of the transplant kidney were measured using laparoscopic ultrasound. Results There was a statistically significant difference in donor types among the groups (P<0.05), while other donor information and recipient's preoperative general data showed no statistically significant differences (all P>0.05). There were no statistically significant differences in serum creatinine and complications at 30 days and 1 year postoperatively among the groups (all P>0.05). The OKT group and 7 mmHg group had more intraoperative urine output than the 13 mmHg group. Both RAKT groups had less intraoperative blood loss and shorter hospital stays than the OKT group, and longer operation times than the OKT group (all P<0.05). There were no statistically significant differences in operation time, intraoperative blood loss, and hospital stay between the two RAKT groups (all P>0.05). The vascular flow velocity of the transplant kidney decreased at 13 mmHg compared to 7 mmHg pneumoperitoneum pressure, but the differences were not statistically significant (all P>0.05). Conclusions Controllable pneumoperitoneum pressure has a limited impact on the vascular flow velocity of the transplanted kidney. RAKT is a safe and effective surgical method under appropriate pneumoperitoneum pressure, and choosing a lower pneumoperitoneum pressure is more conducive to the early recovery of renal function postoperatively.

Objective To explore the learning curve of robotic-assisted kidney transplantation(RAKT).Methods The clinical data of 96 consecutive RAKT patients performed by the same surgical team were retrospectively analyzed.The arterial anastomosis time,venous anastomosis time,ureteral anastomosis time,hospital stay,and blood loss were selected as evaluation indicators.The learning curve of RAKT was analyzed using the cumulative sum(CUSUM),and the curve was divided into the learning improvement stage and the proficient mastery stage according to the learning curve.The learning curve was verified by comparing the general data and surgical data of patients in different learning stages,and the clinical efficacy of each stage was analyzed.Results The optimal fitting equation of the learning curve reached its peak at the 33rd case,which was the minimum number of surgeries required to master RAKT.There was no statistically significant difference in age,gender,dialysis type,previous abdominal surgery history,number of donor renal arteries,and preoperative serum creatinine between the learning improvement group and the proficient mastery group(all P>0.05).Compared with the learning improvement stage,the body mass index(BMI)was higher,and the number of right donor kidney was increased compared to the left donor kidney in the proficient mastery stage(both P<0.05).There were no significant differences in arterial anastomosis time,ureteral anastomosis time,postoperative serum creatinine,and complications between the two groups(all P>0.05).The iliac vessel dissection time,warm ischemia time,venous anastomosis time,blood loss,and hospital stay in the proficient mastery stage were superior to those in the learning improvement stage,with statistically significant differences(all P<0.05).Conclusions RAKT requires at least 33 cases to cross the learning curve.There is no difference in complications and recovery of transplant renal function between the learning improvement stage and the proficient mastery stage.

Critical care medicine-related treatment is an interdisciplinary and multi-professional process,often leading to secondary or concomitant mental disorders in clinical practice.Currently,there is no consensus on the pharmacological treatment of related mental illnesses in China.The Chinese Society of Psychosomatic Medicine collaborated with the Critical Care Medicine expert group to form a consensus writing expert group.After a systematic review of relevant literature,summarizing published domestic and foreign literature,and extensive discussions,the consensus was developed.The consensus elaborates on the principles and processes of the standardized use of psychotropic drugs in critical care medicine,as well as the clinical indications,precautions,and specific drug selection of various psychiatric medications,providing feasible suggestions and guidance for the clinical application of psychiatric medications in the intensive care unit.

Objective:To investigate the effects of modified endoscopic retrograde appendicitis therapy (mERAT) on the treatment of children with different severities of acute appendicitis.Methods:This study was a case-control study. A total of 586 children with acute appendicitis, who were admitted to the Pediatric Department of Second Affiliated Hospital of Air Force Medical University between January 2019 and November 2023, were selected as the research subjects. According to the severity of the disease, the patients were divided into simple appendicitis group, suppurative appendicitis group and perforated appendicitis group. The baseline data, hospitalization treatment and costs, outcomes, and recurrence in each group were analyzed, and the difference in the effectiveness of mERAT between the groups were compared by Kruskal-Wallis H test and χ2 test. Results:Among 586 children, there were 338 males and 248 females. The age at onset was 7.0 (4.6, 9.4) years. There were 475 cases of simple appendicitis, 78 cases of suppurative appendicitis, and 33 cases of perforated appendicitis. There were no significant differences in age and gender among the three groups ( F=0.59, χ2=3.31, both P>0.05). However, there were statistically significant differences in body temperature, white blood cell counts, neutrophil percentage, lymphocyte percentage, nausea or vomiting, right lower abdominal pain, umbilical pain, right lower abdominal tenderness, and right lower abdominal rebound pain ( H=7.56, 161.52, 169.11, and 169.61, χ2=12.05, 13.82, 12.05, 7.74, 20.35, and 94.61, all P<0.05). Also, the treatment time, postoperative hospital stay, total hospital stay, and cost showed statistically significant differences ( H=4.70, 33.66, 34.99, 30.37, all P<0.05). There was no significant difference in the initial treatment success rate (98.1% (466/475) vs. 98.7% (77/78) vs. 90.9% (30/33), P=0.057). During the 30 (23, 36) months of follow-up, the recurrence rate was 7.9% (35/433) in the simple appendicitis group, 20.8% (15/72) in the suppurative appendicitis group, and 30.0% (9/30) in the perforated appendicitis group, with a statistically significant difference ( χ2=23.56, P<0.001). Among the children with recurrent appendicitis, 15 cases still chose mERAT, of them 11 cases (31.2%) had simple appendicitis, 2 cases (2/15) had suppurative appendicitis, and 2 cases (2/9) had perforated appendicitis.The latest time to recurrence in the 3 groups was 32, 35 and 10 months, respectively. Conclusion:Treatment with mERAT has a good effect in pediatric simple appendicitis, but has a higher recurrence rate despite a better initial treatment success rate in suppurative appendicitis and perforated appendicitis.

Human Respiratory Syncytial Virus (HRSV) is a serious threat to the population health. The elderly are one of the susceptible populations. The prevalence of HRSV in the elderly is generally higher than that in other age groups except children, which has gradually attracted attention in recent years. This paper reviewed the prevalence, common complications and major complications of HRSV in the elderly, briefly expounded the economic burden of HRSV infection, and proposed that attention should be paid to the disease burden of the elderly after HRSV infection, timely treat common complications, so as to reduce the occurrence of adverse survival outcomes and provide scientific evidence for the prevention and control of HRSV infection in the elderly.

This study aims to investigate the effects of baicalein(BAI) on lipopolysaccharide(LPS)-induced human microglial clone 3(HMC3) cells, with a focus on suppressing inflammatory responses and elucidating the potential mechanism underlying the therapeutic effects of BAI on ischemic stroke via modulating the cAMP-PKA-NF-κB/CREB pathway. The findings have significant implications for the application of traditional Chinese medicine in treating cerebral ischemic diseases. First, the safe dosage of BAI was screened, and then an inflammation model was established with HMC3 cells by induction with LPS for 24 h. The cells were assigned into a control group, a model group, and high-, medium-, and low-dose(5, 2.5, and 1.25 μmol·L~(-1), respectively) BAI groups. The levels of superoxide dismutase(SOD) and malondialdehyde(MDA) in cell extracts, as well as the levels of interleukin-1β(IL-1β), IL-6, tumor necrosis factor-α(TNF-α), and cyclic adenosine monophosphate(cAMP) in the cell supernatant, were measured. Western blot was performed to determine the expression of protein kinase A(PKA), phosphorylated cAMP-response element binding protein(p-CREB), and nuclear factor-kappa B p65(NF-κB p65). Hoechst 33342/PI staining was employed to assess cell apoptosis. High and low doses of BAI were used for treatment in the research on the mechanism. The results revealed that BAI at the concentrations of 10 μmol·L~(-1) and below had no impact on normally cultured HMC3 cells. LPS induction at 200 ng·mL~(-1) for 24 h reduced the SOD activity and increased the MDA content in HMC3 cells. However, 5, 2.5, and 1.25 μmol·L~(-1) BAI significantly increased the SOD activity and 5 μmol·L~(-1) BAI significantly decreased the MDA content. In addition, BAI ameliorated the M1 polarization of HMC3 cells induced by LPS, as indicated by cellular morphology. The results of ELISA demonstrated that BAI significantly lowered the levels of TNF-α, IL-1β, IL-6, and cAMP in the cell supernatant. Western blot revealed that BAI up-regulated the protein levels of PKA and p-CREB while down-regulating the expression of NF-κB p65. Hoechst 33342/PI staining results indicated that BAI mitigated the apoptosis of HMC3 cells. Overall, the results indicated that BAI had protective effects on the HMC3 cells induced by LPS, and could inhi-bit inflammatory response and improve cell apoptosis, which might be related to the regulation of the cAMP-PKA-NF-κB/CREB pathway.
