Objective:To evaluate the effect of acupuncture on postoperative delirium (POD) in diabetic patients undergoing surgery under general anesthesia.Methods:In this randomized controlled trial, 92 diabetic patients of either sex, aged 30-80 yr, with a body mass index of 18-28 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective surgery under general anesthesia, were divided into 2 groups ( n=46 each) using a table of random numbers: control group (group C) and acupuncture group (group A). Group A received acupuncture at the Baihui (GV20), Shenting (GV24) and Sishencong (EX-HN1) acupoints before anesthesia. The needles were retained for 30 min, with manual stimulation applied every 10 min for 10 s each time. After 4 stimulations, routine anesthesia was carried out. Group C received routine anesthesia only. Regional cerebral oxygen saturation was recorded on admission to the operating room (T 0), after anesthesia induction (T 1), at the start of surgery (T 2), at the end of surgery (T 3), and immediately after tracheal extubation (T 4). The POD developed within 3 days after surgery was assessed. The occurrence of needle-related adverse effects such as fainting, subcutaneous bleeding, and local paresthesia was recorded. Results:Compared with group C, the incidence of POD was significantly reduced, and the regional cerebral oxygen saturation was increased at T 1, 4 in group A ( P<0.05). Conclusions:Acupuncture can decrease the development of POD in diabetic patients undergoing surgery under general anesthesia, which is related to an increase in regional cerebral oxygen saturation.

Objective:To understand the epidemiological characteristics and spatiotemporal distribution of viral encephalitis in children and adolescents in Henan Province from 2012 to 2023.Methods:The information about viral encephalitis cases from October 1, 2012 to July 26, 2023 were collected from Zhengzhou Children's Hospital (National Children's Regional Medical Center),Henan Provincial Children's Hospital for the analyses on temporal distribution the cases, the severe illness rate, age distribution, pathogen type and imaging findings of the cases.Results:A total of 6 276 cases of viral encephalitis were included in this study after excluding cases with incomplete information. The cases mainly originated from Zhengzhou (38.96%), followed by Zhoukou (9.93%), Xuchang (8.68%), Zhumadian (7.90%) and Pingdingshan (7.39%). The cases in boys accounted for 62.13% and the cases in girls accounted for 37.87%. Most cases (72.45%) occurred in age group 7-13 years. The overall rate of severe illness cases was 4.51% from 2012 to 2023. There were significant differences in severe illness cases among different areas and years ( χ2=5.33, P=0.021; χ2=48.14, P<0.001). Enteroviruses were mainly detected (31.57%), in which Coxsackie virus was predominant (58.37%). Imaging findings showed that cerebral hemisphere damage was most common in children and adolescents with viral encephalitis (54.93%). Conclusions:From 2012 to 2023, more cases of viral encephalitis occurred in boys in Henan. Children and adolescents aged 7-13 years were the main affected group. The prevention of enteroviruses infection, especially Coxsackie virus, needs to be strengthened. Special attention should be paid to the prevention of cerebral hemisphere damage after viral encephalitis diagnosis.

Objective:To study the expression level of programmed death ligand 1 (PD-L1) in combined hepatocellular-cholangiocarcinoma (cHCC-CCA) and its correlation with the clinical characteristics and prognosis.Methods:The clinical data of 75 patients with cHCC-CCA undergoing surgery in Tianjin Medical University Cancer Institute and Hospital from January 2011 to December 2019, including 61 males and 14 females, with a median age of 55 years (36 to 77). Immunohistochemistry was conducted to determine the PD-L1 expression in tumor. The status of PD-L1 expression, clinicopathological data and prognosis of patients were analyzed.Results:In low-differentiated cHCC-CCA tissues, the proportion of PD-L1 expression (21.1%, 8/38) was higher than that in moderately to well-differentiated cHCC-CCA tissues (2.70%, 1/37, χ2=4.366, P=0.037). The median disease-free survival (DFS) and overall survival (OS)of PD-L1 positive patients were 12.3 and 15.1 months, respectively, lower than those of PD-L1 negative patients (14.4 and 23.3 months). The difference of DFS was statistically significant ( χ2=4.052, P=0.044). In multivariate analysis, major vascular invasion (DFS: HR=1.965, 95% CI: 1.119-3.450, P=0.019; OS: HR=1.781, 95% CI: 1.022-3.105, P=0.042) and lymph node metastasis (DFS: HR=2.451, 95% CI: 1.1033-5.814, P=0.042; OS: HR=2.652, 95% CI: 1.120-6.279, P=0.027) were identified as independent prognostic factors affecting DFS and OS. Conclusions:The proportion of PD-L1 positive is higher inthe low-differentiated cHCC-CCA tissue compared to that in moderately to well-differentiated cHCC-CCA. The major vascular invasion and lymph node metastasis are independent factors affecting the prognosis of patients with cHCC-CCA.

Objective:To investigate the association between the pathogenesis of hepatitis B e antigen (HBeAg)-positive chronic hepatitis B and the frequency and function of plasmacytoid dendritic cell (pDC) in patients HBeAg-positive chronic hepatitis B virus infection.Methods:A total of 49 HBeAg (+ ) patients with chronic hepatitis B virus infection in immune tolerance phase (IT) and 100 patients in immune clearance phase (IC) were enrolled. The viral serological indicators and liver function were detected. Peripheral venous blood samples were collected. The peripheral blood pDC frequency and the quantitative expression of co-stimulatory molecule CD86 were detected by flow cytometry, and the correlation between the onset of chronic hepatitis B and the frequency and function of pDC was analyzed.Results:In IC group, hepatitis B surface antigen (HBsAg) levels, HBeAg levels and hepatitis B virus (HBV) DNA loads were significantly lower than those in IT group, and alanine aminotransferase (ALT) levels in IC group were significantly higher than that in IT group; pDC% in IC group was significantly lower than that in IT group; CD86 + pDC% and CD86 mean fluorescentintensity (MFI) showed no significant difference between the two groups. In the IC group, the baseline pDC% was negatively correlated with ALT levels, while CD86 + pDC%, CD86MFI, and CD86 antibody binding capacity (ABC) had no remarkable correlation with ALT levels. Conclusions:The frequency of pDC was correlated with the pathogenesis of CHB. The lower the frequency of pDC in patients with CHB, the more prone to hepatitis. Therefore, increasing the frequency of pDC may inhibit the occurrence of hepatitis.

Objective: To investigate the correlation between the frequency and function of early plasmacytoid dendritic cells (pDC) and the treatment response in patients with HBeAg-positive chronic hepatitis B receiving entecavir (ETV). Methods: Patients with HBeAg-positive chronic hepatitis B were enrolled. Antiviral therapy with ETV, serum serological markerso hepatitis B virs (HBV) infection and liver function (HBV DNA load, HBsAg/anti-HBs, HBeAg and anti-HBe levels, and ALT levels) were monitored every three months before and during treatment; the efficacy of ETV was assessed by changes in the level of HBV DNA. Peripheral venous blood was collected before treatment, at 12 weeks and 24 weeks, respectively. Flow cytometry was used to detect the frequency of peripheral blood pDC and the surface co-stimulatory molecule CD86. The baseline and early treatment (12 weeks and 24 weeks) pDC frequency and functional changes were analyzed. Results: Of the 100 patients with chronic hepatitis B, 45 patients received ETV treatment and 48 weeks of follow-up. Within 48 weeks of ETV treatment, HBsAg levels decreased by 0.53±0.78 log IU/mL; HBeAg decreased by 816.61S/CO, and HBeAg seroconversion occurred in 4 cases; HBV DNA content decreased by 6.04±1.12 log IU/mL, in 33 cases (73%) the HBV DNA became undetectable, in 43 cases ALT kept normal continuously for more than 3 months. In the early stage of ETV treatment, pDC% increased significantly, CD86+ pDC%, CD86MFI and CD86ABC showed no significant changes. In ETV-treated HBV DNA responders, pDC% increased significantly, CD86+ pDC%, CD86MFI and CD86ABC showed no significant changes; HBV DNA non-responders had a significant increase in pDC%, but CD86+ pDC% decreased significantly, and CD86MFI and CD86ABC showed no significant changes. The decrease in HBsAg and HBeAg levels in ETV treated patients was not significantly associated with early pDC%, CD86+ pDC%, CD86MFI and CD86ABC changes. Conclusions ETV treatment can directly inhibit the replication of HBV DNA, but does not enhance the function of immune cells.

Objective To explore the clinical features of chronic myelogenous leukemia (CML) combined with solid malignant neoplasms. Methods The clinical data of 8 CML patients with solid malignant neoplasms who were admitted to the Affiliated Tumor Hospital of Zhengzhou University, the Central Hospital of Nanyang City, the First Affiliated Hospital of Science and Technology University of Henan, and the Central Hospital of Xinxiang City from August 2006 to August 2018 were analyzed retrospectively. The clinical features, treatment and prognosis of the patients were summarized with the review of literature. Results Among the 8 patients, 3 were male and 5 female, aged 40-76 years, with a median of 50 years old. Seven cases were in CML chronic phase, and 1 was in accelerated phase. Seven patients were treated with tyrosine kinase inhibitor (TKI), and only 1 patient was treated with hydroxyurea. In 8 patients, two cases presented with synchronous multiple primary cancer (SMPC), 6 cases presented with heterochrony multiple primary cancer (HMPC). two patients received the operation, 1 patient received the operation and chemotherapy, 4 patients received chemotherapy, and 1 patient received the isotope treatment. One SMPC patient died and another one was under treatment, and 6 HMPC patients were under treatment. ConclusionsThe relationship between CML and solid malignant neoplasm is under discussion, but patients with CML and solid malignant neoplasm are not unusual. Clinicians should raise awareness to avoid misdiagnosis. The treatment should follow the two main lines that are comprehensive treatment and individualized treatment.
