OBJECTIVE: To compare the clinical efficacy of unilateral biportal endoscopic discectomy(UBE) and percutaneous interlaminar endoscopic discectomy(PIED) in the treatment of highly migrated lumbar disc herniation (LDH). METHODS: A retrospective analysis was conducted on 43 patients with highly migrated LDH who underwent spinal endoscopic surgery between January 2022 and December 2023. In the UBE group 22 patients included 8 males and 14 females, aged 49 to 59 years old with a mean of (54.13±2.07) years old. In the PIED group 21 patients included 11 males and 10 females, aged 49 to 59 years old with a mean of (55.04±2.80) years old. Perioperative parameters including intraoperative blood loss, operative time, and fluoroscopic exposures were compared between groups. Clinical outcomes were assessed using the visual analogue scale (VAS) for pain, Oswestry disability index (ODI), and modified MacNab criteria. Complications during the perioperative period and follow-up were recorded. RESULTS: In the PIED group, there were 3 cases of nerve injury, 1 case of residual nucleus pulposus, and 1 case of dural injury. In the UBE group, there was 1 case of nerve injury and 1 case of cerebrospinal fluid leakage. No infections or major bleeding occurred in either group. All patients completed surgery and were followed up for at least 12 months. The UBE group had significantly more intraoperative blood loss (39.09±6.10) ml and more fluoroscopic exposures (6.45±0.26) than the PIED group (34.05±5.62) ml and (3.24±0.28) with significant difference (P<0.05). Preoperative VAS and ODI showed no significant differences between two groups (P>0.05). Both groups demonstrated significant improvements in VAS and ODI postoperatively (P<0.001). At the 3rd days postoperatively, the UBE group had a significantly lower leg pain VAS (2.27±0.20) than the PIED gruop(2.95±0.24) with significant difference (P<0.05), but no significant differences were observed at the first or 12th months (P>0.05). No significant differences in ODI were found between two groups during follow-up (P>0.05). At the 1st month postoperatively, according to modified MacNab criteria, 15 patients got excellent results, 4 good, and 2 fair in PIED group;and 18 patients got excellent results, 2 good, and 2 fair in UBE group, with no significant difference between two groups(P>0.05). CONCLUSION Both PIED and UBE are effective surgical methods for treating highly migrated LDH. Compared with PIED, UBE involves slightly longer operative time, more blood loss, and more fluoroscopic exposures, but carries a lower risk of nerve injury.

OBJECTIVE: To elucidate the effect of Huanglian-Renshen-Decoction (HRD) on ameliorating type 2 diabetes mellitus by maintaining islet β -cell identity through regulating paracrine and endocrine glucagon-like peptide-1 (GLP-1)/GLP-1 receptor (GLP-1R) in both islet and intestine. METHODS: The db/db mice were divided into the model (distilled water), low-dose HRD (LHRD, 3 g/kg), high-dose HRD (HHRD, 6 g/kg), and liraglutide (400 µ g/kg) groups using a random number table, 8 mice in each group. The db/m mice were used as the control group (n=8, distilled water). The entire treatment of mice lasted for 6 weeks. Blood insulin, glucose, and GLP-1 levels were quantified using enzyme-linked immunosorbent assay kits. The proliferation and apoptosis factors of islet cells were determined by immunohistochemistry (IHC) and immunofluorescence (IF) staining. Then, GLP-1, GLP-1R, prohormone convertase 1/3 (PC1/3), PC2, v-maf musculoaponeurotic fibrosarcoma oncogene homologue A (MafA), and pancreatic and duodenal homeobox 1 (PDX1) were detected by Western blot, IHC, IF, and real-time quantitative polymerase chain reaction, respectively. RESULTS: HRD reduced the weight and blood glucose of the db/db mice, and improved insulin sensitivity at the same time (P<0.05 or P<0.01). HRD also promoted mice to secrete more insulin and less glucagon (P<0.05 or P<0.01). Moreover, it also increased the number of islet β cell and decreased islet α cell mass (P<0.01). After HRD treatment, the levels of GLP-1, GLP-1R, PC1/3, PC2, MafA, and PDX1 in the pancreas and intestine significantly increased (P<0.05 or P<0.01). CONCLUSION HRD can maintain the normal function and identity of islet β cell, and the underlying mechanism is related to promoting the paracrine and endocrine activation of GLP-1 in pancreas and intestine.

Eightly-four novel thioheterocyclic nucleoside derivatives were designed, synthesized, and evaluated for antitumor activity in vitro and in vivo. Most of the compounds inhibited the growth of HCT116 and HeLa cancer cells in vitro, among them 33a and 36b exhibited potent activity against HCT116 cells (IC₅₀ = 0.27 and 0.49 μmol/L, respectively). Both compounds 33a and 36b inhibited cell metastasis, arrested the cell cycle in the G₂/M phase, and induced apoptosis in vitro. Mechanistic studies revealed that 33a and 36b increased ROS levels, led to DNA damage, ER stress, and mitochondrial dysfunction, and inhibited autophagy in HCT116 cells. Biological information analysis, RNA-sequencing, Gene Set Enrichment Analysis (GSEA), drug affinity responsive target stability (DARTS) assay, cellular thermal shift assay (CETSA), and SPR experiments identified that compounds 33a and 36b showed antitumor activity by suppressing the c-MYC pathway. c-MYC silencing assays indicated that c-MYC proteins participated in 33a-mediated anticancer activities in HCT116 cells. More importantly, compound 33a presented favorable pharmacokinetic properties in mice (T _1/2 = 6.8 h) and showed significant antitumor efficacy in vivo without obvious toxicity, showing promising potential for further clinical development.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective:To investigate the influencing factors of pathologic complete response (pCR) after neoadjuvant chemoradiotherapy (NCRT) in patients with locally advanced esophageal squamous cell carcinoma (ESCC), and to compare the clinical prognosis of ESCC patients with and without pCR after NCRT (40 Gy/ 20F).Methods:Among patients enrolled in a prospective clinical study, 87 ESCC patients treated with NCRT followed by surgery in Tianjin Medical University Cancer Institute & Hospital between June 2015 and October 2019 were selected. They were divided into the pCR ( n=35) and non-pCR groups ( n=52). Clinicopathological characteristics were retrospectively analyzed and subsequent follow-up was performed. Clinical prognosis and influencing factors were compared between two groups by using Kaplan-Meier and Cox regression analyses. Results:After NCRT, 40% of the ESCC patients could achieve pCR. Univariate analysis showed that patients in the pCR group had a disease-free survival (DFS) of 39.3 months and an overall survival (OS) of 64.0 months. In comparison, patients in the non-pCR group had a DFS of only 14.1 months and an OS of only 25.2 months. The differences were statistically significant (DFS: P<0.01, OS: P<0.05). Multivariate analysis revealed that whether pCR or not after NCRT, age, number of primary lesions, evaluation results after NCRT and postoperative pathological outcomes were important prognostic factors. The differences were statistically significant between two groups (all P<0.05). Conclusion:pCR after NCRT is significantly correlated with long-time survival of patients with ESCC, and pCR after NCRT has an important value in predicting clinical prognosis for long-term survival of ESCC patients.

OBJECTIVE: To investigate whether Omicron BA.1 breakthrough infection after receiving the SARS-CoV-2 vaccine could create a strong immunity barrier. METHODS: Blood samples were collected at two different time points from 124 Omicron BA.1 breakthrough infected patients and 124 controls matched for age, gender, and vaccination profile. Live virus-neutralizing antibodies against five SARS-CoV-2 variants, including WT, Gamma, Beta, Delta, and Omicron BA.1, and T-lymphocyte lymphocyte counts in both groups were measured and statistically analyzed. RESULTS: The neutralizing antibody titers against five different variants of SARS-CoV-2 were significantly increased in the vaccinated population infected with the Omicron BA.1 variant at 3 months after infection, but mainly increased the antibody level against the WT strain, and the antibody against the Omicron strain was the lowest. The neutralizing antibody level decreased rapidly 6 months after infection. The T-lymphocyte cell counts of patients with mild and moderate disease recovered at 3 months and completely returned to the normal state at 6 months. CONCLUSION Omicron BA.1 breakthrough infection mainly evoked humoral immune memory in the original strain after vaccination and hardly produced neutralizing antibodies specific to Omicron BA.1. Neutralizing antibodies against the different strains declined rapidly and showed features similar to those of influenza. Thus, T-lymphocytes may play an important role in recovery.

Objective: To investigate the clinical features and long-term prognosis of primary biliary cholangitis (PBC) in patients with past hepatitis B virus (HBV) infection. Methods: 353 cases with PBC who visited the Liver Disease Center of Beijing Friendship Hospital Affiliated to Capital Medical University between January 2000 and January 2018 were retrospectively analyzed and were divided into the past HBV infection group (156 cases) and the no HBV infection group (197 cases). The two groups' baseline clinical features were compared. Ursodeoxycholic acid response rate after one year, GLOBE score, UK-PBC score, and long-term liver transplantation-free survival rate were compared through outpatient and telephone follow-up. Results: PBC with past HBV infection had a significantly reduced female proportion compared to the no HBV infection group (91.9% vs. 79.5%, P = 0.001). However, there were no statistically significant differences in age, biochemical indices, immunological indicators, platelet count, cirrhosis proportion, and others. Ursodeoxycholic acid biochemical response rate was reduced in patients with past HBV infection at the end of one year of treatment, but the difference was not statistically significant (65.8% vs. 78.2%, P = 0.068). In addition, there were no statistically significant differences between the GLOBE score (0.57 vs. 0.59, P = 0.26) and UK-PBC 5-year (2.87% vs. 2.87%, P = 0.38), 10-year (9.29% vs. 8.2%, P = 0.39) and 15-year liver transplantation rates (16.6% vs. 14.73%, P = 0.39). Lastly, the overall 5-year liver transplantation-free survival rate had no statistically significant difference between the two groups of patients (86.4% vs. 87.5%, P = 0.796). Conclusion: Primary biliary cholangitis had no discernible effect in terms of age at onset, biochemical indices, immunological indicators, cirrhosis proportion, ursodeoxycholic acid response rate after one year, GLOBE score, UK-PBC score, or overall liver transplantation-free survival rate in patients with past hepatitis B virus infections.

Objective: To evaluate the efficacy and safety of HLA-haploidentical hematopoietic stem cell transplantation (allo-HSCT) for hepatitis-related aplastic anemia (HRAA) patients. Methods: Retrospective analysis was performed on hepatitis-associated aplastic anemia patients who received haplo-HSCT at our center between January 2012 and June 2022. October 30, 2022 was the final date of follow-up. Results: This study included 28 HRAA patients receiving allo-HSCT, including 18 males (64.3% ) and 10 females (35.7% ), with a median age of 25.5 (9-44) years. About 17 cases of severe aplastic anemia (SAA), 10 cases of very severe aplastic anemia (VSAA), and 1 case of transfusion-dependent aplastic anemia (TD-NSAA) were identified. Among 28 patients, 15 patients received haplo-HSCT, and 13 received MSD-HSCT. The 2-year overall survival (OS) rate, the 2-year failure-free survival (FFS) rate, the 2-year transplant-related mortality (TRM) rate, the 100-day grade Ⅱ-Ⅳ acute graft-versus-host disease (aGVHD) cumulative incidence rate, and the 2-year chronic graft-versus-host disease (cGVHD) cumulative incidence rate were 81.4%, 81.4% (95% CI 10.5% -20.6% ), 14.6% (95% CI 5.7% -34.3% ), 25.0% (95% CI 12.8% -45.4% ), and 4.2% (95% CI 0.6% -25.4% ), respectively. After transplantation, all patients had no significant liver function damage. Compared with the MSD-HSCT group, only the incidence of cytomegaloviremia was significantly higher in the haplo-HSCT group [60.0% (95% CI 35.2% -84.8% ) vs 7.7% (95% CI 0-22.2% ), P=0.004]. No statistically significant difference in the Epstein-Barr virus was found in the 2-year OS, 2-year FFS, 2-year TRM, and 100-day grade Ⅱ-Ⅳ aGVHD cumulative incidence rates and 2-year cGVHD cumulative incidence rate. Conclusion: Allo-HSCT is safe and effective for HRAA, and haplo-HSCT can be used as a safe and effective alternative for newly diagnosed HRAA patients who cannot obtain HLA-matched sibling donors.
