OBJECTIVE: To investigate the mechanism of human embryonic stem cell-derived mesenchymal stem cells (hESC-MSC) in alleviating brain injury after resuscitation in swine with cardiac arrest (CA). METHODS: Twenty-nine healthy male large white swine were randomly divided into Sham group (n = 9), cardiopulmonary resuscitation (CPR) group (n = 10) and hESC-MSC group (n = 10). The Sham group only completed animal preparation. In CPR group and hESC-MSC group, the swine model of CA-CPR was established by inducing ventricular fibrillation for 10 minutes with electrical stimulation and CPR for 6 minutes. At 5 minutes after successful resuscitation, hESC-MSC 2.5×10⁶/kg was injected via intravenous micropump within 1 hour in hESC-MSC group. Venous blood samples were collected before resuscitation and at 4, 8, 24, 48 and 72 hours of resuscitation. The levels of neuron specific enolase (NSE) and S100B protein (S100B) were detected by enzyme linked immunosorbent assay (ELISA). At 24, 48 and 72 hours of resuscitation, neurological deficit score (NDS) and cerebral performance category (CPC) were used to evaluate the neurological function of the animals. Three animals from each group were randomly selected and euthanized at 24, 48, and 72 hours of resuscitation, and the hippocampus tissues were quickly obtained. Immunofluorescence staining was used to detect the distribution of hESC-MSC in hippocampus. Immunohistochemical staining was used to detect the activation of astrocytes and microglia and the survival of neurons in the hippocampus. The degree of apoptosis was detected by TdT-mediated dUTP nick end labeling (TUNEL). RESULTS: The serum NSE and S100B levels of brain injury markers in CPR group and hESC-MSC group were significantly higher than those in Sham group at 24 hours of resuscitation, and then gradually increased. The levels of NSE and S100B in serum at each time of resuscitation in hESC-MSC group were significantly lower than those in CPR group [NSE (μg/L): 20.69±3.62 vs. 28.95±3.48 at 4 hours, 27.04±5.56 vs. 48.59±9.22 at 72 hours; S100B (μg/L): 2.29±0.39 vs. 3.60±0.73 at 4 hours, 2.38±0.15 vs. 3.92±0.50 at 72 hours, all P < 0.05]. In terms of neurological function, compared with the Sham group, the NDS score and CPC score in the CPR group and hESC-MSC group increased significantly at 24 hours of resuscitation, and then gradually decreased. The NDS and CPC scores of hESC-MSC group were significantly lower than those of CPR group at 24 hours of resuscitation (NDS: 111.67±20.21 vs. 170.00±21.79, CPC: 2.33±0.29 vs. 3.00±0.00, both P < 0.05). The expression of hESC-MSC positive markers CD73, CD90 and CD105 in the hippocampus of hESC-MSC group at 24, 48 and 72 hours of resuscitation was observed under fluorescence microscope, indicating that hESC-MSC could homing to the damaged hippocampus. In addition, compared with Sham group, the proportion of astrocytes, microglia and apoptotic index in hippocampus of CPR group were significantly increased, and the proportion of neurons was significantly decreased at 24, 48 and 72 hours of resuscitation. Compared with CPR group, the proportion of astrocytes, microglia and apoptotic index in hippocampus of hESC-MSC group decreased and the proportion of neurons increased significantly at 24 hours of resuscitation [proportion of astrocytes: (14.33±1.00)% vs. (30.78±2.69)%, proportion of microglia: (12.00±0.88)% vs. (27.89±5.68)%, apoptotic index: (12.89±3.86)% vs. (52.33±7.77)%, proportion of neurons: (39.44±3.72)% vs. (28.33±1.53)%, all P < 0.05]. CONCLUSIONS Application of hESC-MSC at the early stage of resuscitation can reduce the brain injury and neurological dysfunction after resuscitation in swine with CA. The mechanism may be related to the inhibition of immune cell activation, reduction of cell apoptosis and promotion of neuronal survival.

To summarize and analyze the clinical data of one case of kidney transplantation in an HIV-positive child with end-stage renal disease (ESRD) in the Department of Transplantation, the People's Hospital of Guangxi Zhuang Autonomous Region, and to explore the safety and efficacy of kidney transplantation in HIV-positive children with ESRD. This pediatric recipient was found to be HIV-positive at birth and underwent kidney transplantation due to ESRD, with good postoperative recovery. During the 2.5-year follow-up, no rejection or rebound in HIV RNA levels was observed. The function of the transplanted kidney was good, and the quality of life was comparable to that of healthy individuals. It suggests that kidney transplantation in HIV-positive children with ESRD is safe and effective under adequate preoperative preparation and close postoperative follow-up.

This study investigates the feasibility of the VP8*protein as a subunit vaccine target for porcine rotavirus A(PoRVA),a major causative agent of diarrhea in piglets.The VP8* genes of PoRVA P[13]and P[23]genotype strains were amplified by RT-PCR.These genes were then liga-ted into the pET-28a(+)vector,yielding recombinant plasmids pET-28a-XJWF1-VP8*-P[23]and pET-28a-ShXYW13-VP8*-P[13].These plasmids were subsequently transformed into BL21(DE3)competent cells.The VP8*protein,induced by IPTG,was purified using affinity chroma-tography,and its expression and purification were verified by SDS-PAGE and Western blot.The purified VP8* protein was used to immunize mice,and serum samples were collected after three immunizations.Cross-neutralization assays were conducted to evaluate the ability of the VP8*protein immune serum to neutralize different genotype strains.The results demonstrated the ex-pression of soluble VP8*protein,with SDS-PAGE and Western blot analyses showing that the purified VP8*protein existed in both monomeric(27 kDa)and homodimeric(54 kDa)forms.ELISA results indicated that high levels of antibodies were produced in mice immunized with VP 8*-P[13]and VP8*-P[23]after three immunizations.Serum cross-neutralization assays revealed that the neutralizing titers of PoRVA VP8*-P[13]and VP8*-P[23]immune sera against homol-ogous genotype strains ranged from 1∶4 800 to 1∶19 200,significantly higher than those against heterologous genotype strains(1∶1 200).This suggests that the VP8*protein of different geno-type strains exhibits both antigenic conservation and distinct variability.The data obtained in this study provide a solid foundation for further exploration of the antigenic structure of the PoRVA VP8* protein and the development of novel subunit vaccines.

Objective To investigate the relationship between the five-circuit and six-qi characteristics of birth dates and the prevalence of endometriosis(EMs).Methods Clinical data from 333 EMs patients treated at the Department of Reproductive Medicine,The First Affiliated Hospital of Henan University of Chinese Medicine between March 2022 and March 2025 were collected.Statistical analysis was performed on parameters of the five circuits and six qi of patients' birth dates.Results No statistically significant differences were found in the distribution of heavenly stems,dominant circuits,guest circuits,dominant qi,guest qi,joining of guest qi with dominant qi,or Sitian-Zaiquan among the 333 EMs patients(all P＞0.05).However,significant differences were observed in the distribution of earthly branches,yearly circuits,and circuit-qi combinations(P＜0.05 or P＜0.01).Specifically:(1)The most frequent earthly branch was the"Wei"year(12.3％,41/333);(2)The most common annual circuit was"deficient water circuit"(14.7％,49/333);(3)The predominant circuit-qi combination was"Tong Sui Hui"(23.1％,77/333).Conclusion The development of EMs is associated with specific five circuits and six qi characteristics at birth:(1)Earthly branch of"Wei"year;(2)Annual circuit of"deficient water circuit";(3)Circuit-qi combination of"Tong Sui Hui".These patterns suggest that congenital endowmentl deficiencies in the spleen and kidney systems may predispose individuals to EMs.

Objective:To determine the expression and diagnostic value of peripheral blood lymphocytes and functional activation status in non-Hodgkin lymphoma with hemophagocytic lymphohistiocytosis (NHL-HLH) .Methods:We retrospectively analyzed clinical data from 30 newly diagnosed NHL-HLH patients admitted to Jiangsu Province Hospital from September 2022 to September 2023. We assessed peripheral blood lymphocytes and activation status by flow cytometry. Forty newly diagnosed patients with NHL who received treatment at our hospital during the same period and had lymphocyte and functional activation indexes were selected as the control group. The differences in relative and absolute lymphocyte counts and functional activation indexes between the two groups were compared. The optimal cutoff values for continuous variables were calculated from the receiver operating characteristic curve and logistic regression analysis was used to evaluate the risk factors in NHL patients with HLH.Results:A total of 30 NHL-HLH patients were evaluated, including 12 T-cell lymphoma and 18 B-cell lymphoma patients. Forty individuals were in the control group, which included 19 T-cell lymphoma and 21 B-cell lymphoma patients. The absolute counts of CD3 + T, CD4 + T, CD8 + T, and NK cells, along with the relative count of NK cells, were significantly lower in the HLH group compared with that in the control group (all P values<0.01) . The expression of CD38 and HLA-DR on CD8 + T-cell activated subgroups was significantly higher in the NHL-HLH group compared with that in the control group (CD8 +CD38 +/CD8 + T expression median: 57.4% vs 21.5%, P<0.001; CD8 +CD38 +/CD8 + T expression median: 49.7% vs 33.5%, P=0.028, respectively) . In addition, CD28 expression on CD4 + and CD8 + T cells was significantly higher in NHL-HLH patients ( P<0.01) . ROC curve and multivariate logistic regression analyses revealed that absolute NK cell count ≤72.0 cells/μl, CD4 +CD28 +/CD4 + T >94.2%, and CD8 +CD28 +/CD8 + T >38.4% were risk factors for predicting the occurrence of NHL-HLH patients. The sensitivity and specificity of the regression model were 86.7% and 86.1%, respectively, with an area under the curve of 0.94 ( P<0.001) . Conclusions:In NHL patients with HLH, there was a significant reduction in the absolute number of peripheral blood lymphocyte subpopulations, whereas T-cell function was notably activated. Specifically, absolute counts of NK cells ≤72.0 cells/μl, CD4 +CD28 +/CD4 + T >94.2%, and CD8 +CD28 +/CD8 + T >38.4% were identified as risk factors for predicting the development of NHL-HLH patients. This will assist in early clinical diagnosis and treatment.

Objective:To analyze the efficacy and feasibility of performing a new surgical procedure, tunnel esophagogastrostomy, to perform proximal gastrectomy.Methods:The study cohort comprised 10 consecutive patients who had undergone esophagogastrostomy by the tunnel technique in Jiangsu Cancer Hospital between October 2019 and July 2022. All patients were male. Their average age was (64.2±8.1) years and body mass index (25.5±3.2) kg/m2. Nine had upper gastric body adenocarcinoma, the remaining one having signet ring cell carcinoma. TNM staging of the tumors showed that seven were Stage IA, one Stage IB, one Stage IIA, and one Stage IIIA. Briefly, tunnel esophagogastrostomy is performed as follows: After performing a proximal gastrectomy, a rectangular seromuscular flap (3.0 cm × 3.5 cm) is created. The posterior esophageal wall is sutured to the gastric wall at the orad end of the seromuscular flap 5 cm from the stump with three to four stitches. Next, the stump of the esophagus is opened, the posterior esophageal wall is sutured to the gastric mucosa and submucosa, and the anterior esophageal wall is sutured to the full layer of the stomach. Finally, the caudad end of the seromuscular flap is closed. Data on surgical safety, postoperative morbidity, and postoperative reflux esophagitis were analyzed. All enrolled patients completed endoscopic follow-up 1 year and 2 years after surgery.Results:All procedures were completed. They comprised four cases of laparoscopic assisted surgery, four of DaVinci robotic surgery, and two of open surgery. The mean operation time was 212.7±33.2 mins, mean anastomosis time (51.6±5.3) minutes, mean tunnel preparation time (20.0±3.5) minutes, and mean operative blood loss (90.0±51.6) mL. The time to first postoperative passage of flatus was (64.8±11.5) hours. The mean hospital stay after surgery was (9.2±1.7) days. There were no postoperative complications above Clavien-Dindo Grade II. The mean preoperative Reflux Disease Questionnaire score was (3.3± 0.4) before the surgery, (3.8±1.0) 1 month postoperatively, and (3.3±0.4) 12 months postoperatively. All patients underwent endoscopic follow-up; no anastomotic stenoses were found. However, one patient had Grade A reflux esophagitis 1 year after surgery and another Grade B reflux esophagitis 2 years after surgery.Conclusion:Esophagogastrostomy by the tunnel technique is a safe and feasible means of performing proximal gastrectomy.
