Objective:
To investigate the late identification and its influencing factors of newly reported HIV/AIDS cases in Linhai City, Zhejiang Province from 2015 to 2024, so as to provide a basis for formulating targeted AIDS prevention and control strategies.
Methods:
Data on newly reported HIV/AIDS cases in Linhai City from 2015 to 2024, including demographic characteristics and detection modes, were collected through the HIV/AIDS Comprehensive Control System of the Chinese Disease Prevention and Control Information System. The new identification rate and late identification proportion of HIV/AIDS cases were analyzed. The average annual percent change (AAPC) was used to assess trends in both the new identification rate and late identification proportion from 2015 to 2024. Multivariable logistic regression model was used to analyze the influencing factors for late identification among HIV/AIDS cases.
Results:
A total of 589 newly reported HIV/AIDS cases were documented in Linhai City from 2015 to 2024. The new identification rate declined from 5.08/105 in 2015 to 3.53/105 in 2024 (AAPC=-6.161%, P<0.05). Among them, 225 cases were late identified. After excluding 4 cases with inferred late identification, the late identification proportion increased from 24.53% in 2015 to 58.97% in 2024 (AAPC=7.595%, P<0.05). Multivariable logistic regression analysis indicated that age ≥25 years (25~<50 years, OR=3.569, 95%CI: 1.567-8.130; ≥50 years, OR=8.683, 95%CI: 3.440-21.917) and passive detection (OR=1.730, 95%CI: 1.022-2.928) were associated with a higher risk of late identification. In contrast, being married or having a spouse (OR=0.565, 95%CI: 0.332-0.960) was associated with a lower risk of late identification.
Conclusions
The new identification rate of HIV/AIDS cases in Linhai City from 2015 to 2024 showed a downward trend, while the proportion of late identification exhibited an upward trend. Age, marital status, and detection mode were identified as influencing factors for late identification among HIV/AIDS cases.

Objective:To explore the changes of brain excitation/inhibition balance and gray matter volume (GMV) and their correlations with clinical features in benign childhood epilepsy with centrotemporal spikes (BECTS).Methods:A cross-sectional study was performed; 83 BECTS children enrolled from Department of Diagnostic Radiology, Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University from January 2015 to January 2024 were selected as BECTS group. During the same period, 101 age- and gender-matched healthy children were recruited as healthy control group through advertisements in local primary schools. Data of conventional MRI and resting-state functional MRI (rs-fMRI) of the two groups were collected. Whole brain GMV was analyzed by voxel-based morphometry (VBM), and Hurst index was calculated based on time series data of blood oxygen level dependent (BOLD) signal of rs-fMRI. Correlations of GMV and Hurst index with disease duration and onset age in children with BECTS were explored by Pearson correlation analysis.Results:Compared with the healthy control group, the BECTS group had significantly increased GMV and decreased Hurst index in the bilateral Rolandic region ( P<0.05). Pearson correlation analysis showed that in the BECTS group, GMV in bilateral Rolandic region was negatively correlated with onset age ( r=-0.267, P=0.015) and positively correlated with disease course ( r=0.267, P=0.015); Hurst index in bilateral Rolandic region was positively correlated with onset age ( r=0.323, P=0.003) and negatively correlated with disease course ( r=-0.240, P=0.029); Hurst index was negatively correlated with GMV in bilateral Rolandic region ( r=-0.328, P=0.003). Conclusion:BECTS children have excitation/inhibition imbalance in epilepsy-related regions and cortical structural delay, and both of them are related to onset age and disease course.

Objective:To evaluate the effect of low-opioid anesthesia based on combination of esketamine and dexmedetomidine on the postoperative mood in patients undergoing thoracoscopic surgery.Methods:In this randomized controlled trial, 130 American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ patients of either sex, aged 18-65 yr, with body mass index ≤30 kg/m 2, undergoing elective video-assisted thoracoscopic surgery, were divided into 2 groups using a random number table method: low-opioid anesthesia group and conventional opioid anesthesia group, with 65 patients in each group. The patients in two groups received either a low-opioid anesthesia based on combination of esketamine and dexmedetomidine or a sufentanil-based opioid anesthesia. Depression and anxiety were assessed using the Self-Rating Depression Scale and Self-Rating Anxiety Scale on day 1 before surgery and days 1, 3 and 7 after surgery. The intraoperative consumption of opioid, usage of vasoactive drugs, extubation time, duration of stay in the post-anesthesia care unit, Riker Sedation-Agitation Scale score after extubation, consumption of sufentanil within 24 h postoperatively, and pain score at 24 h postoperatively were recorded, and the occurrence of adverse reactions within 24 h postoperatively was also recorded. Results:Compared with conventional opioid anesthesia group, the postoperative Self-Rating Depression Scale score and incidence of depression were significantly decreased, the Self-Rating Anxiety Scale score and incidence of anxiety were decreased, the intraoperative consumption of opioid was reduced, the usage rate of metaraminol was decreased, the usage rate of nicardipine was increased, the duration of stay in the post-anesthesia care unit was shortened, the Riker Sedation-Agitation Scale score was decreased after tracheal extubation, the consumption of sufentanil was reduced after operation, the pain score was decreased, and the incidence of postoperative nausea and vomiting and dizziness was decreased in low-opioid anesthesia group ( P<0.05). Conclusions:The low-opioid anesthesia based on combination of esketamine and dexmedetomidine can relieve the postoperative depression and anxiety and improve the quality of postoperative recovery when used in patients undergoing thoracoscopic surgery.

Objective:To investigate the influence of TGF-β1 on the malignant transformation of bystander cells after proton irradiation simulating space radiation, and its underlying mechanism.Methods:Normal human bronchial epithelial cells BEAS-2B were exposed to proton irradiation at 0, 0.2, 0.5, and 1.0 Gy to simulate space radiation. Supernatants from cell culture media were collected as a conditioned medium (CM) for treating bystander BEAS-2B cells. The enzyme-linked immunosorbent assay (ELISA) was employed to detect TGF-β1 levels within the CM. The soft agar colony formation assay was performed to assess the rate of malignant transformation of bystander cells. Immunofluorescence and Western blot techniques were utilized to examine the localization of β-arrestin1 in CM-treated bystander cells, with or without the TGF-β1 receptor inhibitor SB525334. The malignant transformation of bystander cells was assessed via soft agar colony formation assay under CM treatment, combined with either a TGF-β1 receptor inhibitor or β-arrestin1 knockdown. Additionally, mRNA and protein levels of epithelial-mesenchymal transition(EMT)-related genes (e.g., E-cadherin, N-cadherin, Fibronectin1, and Vimentin) were analyzed through qRT-PCR and Western blot, respectively.Results:Contrasting with the 0 Gy group, the proton irradiation groups exhibited a dose-dependent increase in TGF-β1 secretion after 24 h ( t=3.38, 8.32, 10.96, P<0.05), and a corresponding rise in the soft agar colony formation rate of CM-treated bystander cells ( t=5.04, 7.20, 10.78, P<0.05). Immunofluorescence and Western blot results indicated that with escalating doses, CM-treated bystander cells showed increased β-arrestin1 into nuclei ( t=7.57, 7.51, P<0.05), being stimulated by TGF-β1 and inhibited by SB525334. The SB525334 application or β-arrestin1 knockdown significantly inhibited the malignant transformation and EMT induced by proton irradiation in bystander cells. This inhibition further reduced the soft agar colony formation rate ( t=2.84, 3.39, P<0.05), and increased mRNA and protein levels of the E-cadherin gene in CM-treated bystander cells exposed to 1 Gy proton irradiation ( t=7.33, 5.38, P<0.05) while reducing the mRNA and protein levels of N-cadherin, Fibronectin1, and Vimentin genes ( t=4.37, 4.10, 5.29, 10.65, 5.15, 3.11, P<0.05). Conclusions:Proton irradiation simulating space radiation can enhance TGF-β1 secretion from lung epithelial cells, inducing β-arrestin1 into nuclei in bystander cells, thereby spurring the malignant transformation of cells. The TGF-β1/β-arrestin1 pathway plays a crucial role in this process.

Gliomas, with their infiltrative growth and malignant potential, present considerable therapeutic challenges. Maximal safe resection is essential for optimizing patient survival and quality of life. Despite this, existing intraoperative visualization techniques suffer from limited sensitivity and accuracy. Label-free Raman spectroscopy has emerged as a non-invasive, rapidly diagnostic, and highly accurate technique. It accurately diagnoses tumors, identifies infiltration margins, and classifies molecular subtypes, enhancing the precision of glioma surgery. This review summarizes the latest advances and applications of label-free Raman spectroscopy in glioma surgery.

Objective To construct nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)knockout mice in order to investigate the effects of NLRP3 knockout on radiation-induced acute pneumonitis and pulmonary fibrosis.Methods Nlrp3+/+and Nlrp3-/-mice were randomly divided into the control group and irradiation group.To induce radiation-caused acute pneumonitis,the control group was exposed to sham irradiation while the irradiation group was exposed to 60Co γ-rays at a dose of 22 Gy at a dose rate of 184.30 R/min.At 14 days post-irradiation,the body weight of each mouse and the wet weight of its lung tissue were measured separately using an analytical balance to calculate the lung coefficient.Quantitative real-time PCR(qPCR)and cytometric bead array(CBA)were used to detect inflammatory responses in lung tissues and serum.Hematoxylin-eosin(HE)staining and F4/80 immunohistochemical staining were used to assess pathological changes and inflammatory cell infiltration in lung tissues.Cysteinyl aspartate specific proteinase-1(caspase-1)activation was analyzed by Western blotting.To establish a model of radiation-induced pulmonary fibrosis,mice were irradiated with 60Co γ-rays at a dose of 18 Gy at a dose rate of 174.67 R/min.At 24 weeks post-irradiation,HE staining and Masson staining were performed to evaluate pulmonary fibrosis.Results NLRP3 knockout inhibited caspase-1 activation,reduced inflammatory responses in lung tissues and serum,suppressed macrophage infiltration,alleviated pulmonary edema,and thereby protected against acute radiation-induced lung injury.Additionally,NLRP3 knockout significantly ameliorated late-stage radiation-induced pulmonary fibrosis.Conclusion NLRP3 knockout can mitigate both early radiation-induced pneumonia and lateradiation-induced pulmonary fibrosis.

Objective To explore the role of dapansutrile(OLT1177)in radiation-induced intestinal injury and the mechanism.Methods C57BL/6J mice were locally irradiated in the abdomen with 60Co to induce a model of radiation-induced intestinal injury.OLT1177 was intraperitoneally injected at a dose of 100 mg/kg 2 hours before irradiation and 6 hours after irradiation before the drug was administered once a day.At 12 hours after irradiation,intestinal tissues were taken for terminal deoxynucleotidyl transferase mediated nick end labeling(TUNEL)staining to detect apoptosis in intestinal tissues.At 4 days after irradiation,mouse serum was collected to detect the levels of inflammatory factors in the serum.Hematoxylin-eosin(HE)stainingwas used for the evaluation of the damage to the intestinal villus structure.Immunohistochemical staining was adopted to detect the changes in crypt proliferation in intestinal tissues.Finally,proteins were isolated from intestinal tissues,and Western blotting was employed to evaluate the activation of nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)inflammasome.Results After irradiation,the intestinal villi in mice were shortened.Meanwhile,there was a notable declinein the number of cells that were proliferating in the crypts,a surge in the number of apoptotic cells,and a significant spike in the overall inflammatory level.However,administration of OLT1177 inhibited the activation of the NLRP3 inflammasome,reduced apoptosis and pyroptosis,decreased the inflammatory level,and thus improved radiation-induced intestinal injury.Conclusion Administration of OLT1177 can significantly mitigate radiation-induced intestinal injury.

Acute-on-chronic liver failure (ACLF) is an acute deterioration of liver function occurring on the basis of chronic liver disease, accompanied by failure of the liver and extrahepatic organs, and is associated with a high short-term mortality rate. Liver transplantation is the only curative treatment for patients with ACLF. However, the shortage of donor livers and limitations of the organ allocation system mean that only a minority of patients can receive transplants. The current organ allocation system based on the model for end-stage liver disease (MELD) score may underestimate the urgency of liver transplantation for ACLF patients. Therefore, it is urgent to develop better assessment tools to determine which ACLF patients are most likely to benefit from liver transplantation. This article reviews the current mainstream definitions of ACLF, the selection of candidates for liver transplantation in ACLF, and the prognostic scoring systems for liver transplantation in ACLF, both domestically and internationally, in order to provide a reference for the prognostic assessment of liver transplantation in ACLF patients.

Objective:To investigate the differences of the glymphatic system (GS) function between patients with mesial temporal lobe epilepsy with hippocampal sclerosis (mTLE-HS) and healthy controls and between different seizure types by using diffusion tensor imaging along perivascular space (DTI-ALPS), and to analyze the correlation between GS function and the course of disease, as well as the efficacy of predicting the surgical outcome.Methods:This study was a cross-sectional study. A total of 171 patients with mTLE-HS (mTLE-HS group) and 75 healthy volunteers (HC group) were retrospectively enrolled from July 2009 to July 2021 at Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University. The general information of all subjects, such as seizure type (partial seizure, secondary generalized seizure), surgical outcome, etc., was analyzed. The 3D magnetization prepared rapid gradient echo T 1WI and DTI sequence images were collected. The VBM analysis method was used to segment cerebrospinal fluid and calculate the volume. The ALPS index of the bilateral brain was calculated using the Atlas-based DTI-ALPS method. Independent sample t-test or paired t test were used to compare the ALPS index between the mTLE-HS group and HC group, and between patients with different seizure types. Pearson correlation analysis was used to analyze the correlation between bilateral ALPS index and disease duration in mTLE-HS group. The predictive value of the ALPS index for surgical outcomes was evaluated by receiver operating characteristics curve and area under the curve. Results:Among the 171 mTLE-HS patients, 98 patients were mTLE with left-side HS (mTLE-LHS) and 73 patients were mTLE with right-side HS (mTLE-RHS); 37 patients underwent surgical treatment, including 27 with good prognosis and 10 with poor prognosis. Compared with the HC group, the left-side ALPS index of mTLE-LHS and mTLE-RHS were both decreased ( P<0.05). The right-side ALPS index in mTLE-RHS was lower than that in the HC group ( P<0.001). There was no significant difference in the right-side ALPS index between mTLE-LHS and HC group ( P=0.080). The ALPS index on the affected side of patients with secondary generalized seizures was significantly lower than that of patients with only partial seizures (all P<0.05), but the difference in ALPS index on the healthy side was not statistically significant( P>0.05). The left-side and right-side ALPS index in mTLE-LHS were negatively correlated with disease duration ( r=-0.272, P=0.007; r=-0.307, P=0.002), but no significant correlation was found between the left-side or right-side ALPS index in mTLE-RHS (all P>0.05). The DTI-ALPS index on the affected side in mTLE-HS patients exhibited good diagnostic accuracy for surgical outcome classification, with an area under the curve of 0.778. Conclusions:The patients with mTLE-HS exhibit dysfunction of the GS, and the degree of impairment is related to the type of seizure and the course of epilepsy. The ALPS index, which characterizes the function of GS, demonstrates good diagnostic accuracy for classifying surgical outcomes.
