The functional modulation of deep brain structures plays a crucial role in the treatment of psychiatric disorders; however, current approaches primarily rely on invasive techniques such as deep brain stimulation. Temporal Interference (TI) transcranial electrical stimulation is an emerging non-invasive neuromodulation technique capable of precisely regulating the activity of deep brain nuclei, offering an innovative and promising approach for psychiatric disorder treatment. In recent years, studies conducted on healthy individuals and patients with neurological disorders (e.g., Parkinson's disease) have provided preliminary evidence supporting the deep brain modulation capabilities of TI. Meanwhile, multiple registered clinical studies are actively investigating its potential applications in psychiatric treatment. This review systematically summarizes the fundamental principles, neuromodulatory mechanisms, and recent research advances of TI in psychiatric disorders. Additionally, it highlights key scientific issues that need to be addressed to facilitate further basic research and clinical translation in this field.

Objective:To establish fingerprints and method for determining the content of two components of Qigong Pills.Methods:High performance liquid chromatography (HPLC) was used to establish the fingerprints of 10 batches of Qigong Pills and common peaks were identified. TCM Chromatographic Fingerprint Similarity Evaluation System (2012 Edition) was used for similarity analysis; the common peaks area was used as indicators, and SIMCA 14.1 was used for cluster analysis and principal component analysis for quality evaluation; a content analysis method was established using hesperidin and Atractylodes macrocephala as indicator components.Results:21 common peaks in the 10 batches of Qigong Pills were identified with the similarity greater than 0.952 (except for the sample S6); the clustering analysis results showed that at a measurement distance of 8, S6 was clustered into one category alone, S1 and S2 were clustered into one category, and the remaining samples were clustered into one major category. The content of hesperidin and Atractylodes macrocephala in 10 batches of Qigong Pills was 3.61-8.92 mg/g and 0.07-0.72 mg/g, respectively.Conclusion:The established HPLC fingerprints and content determination method in this study are stable, reliable, and reproducible, which can provide reference for quality control and evaluation of Qigong Pills.

Objective:To better evaluate the prevalence and epidemiological characteristics of metabolic-associated fatty liver disease (MAFLD) based on liver transient elastography.Methods:It was a cross-sectional study. A total of 6 961 patients without hepatitis, who underwent liver transient elastography examination at the Department of Hepatology, Zhongnan Hospital of Wuhan University from November, 2021 to April, 2022 were included. The patients were categorized into normal and mild, moderate, severe MAFLD groups according to FibroTouch controlled attenuation parameters (CAP). The CAP values among different body mass index (BMI) groups were compared using analysis of variance. The distribution characteristics and the incidence of MAFLD in different age, gender, body mass index(BMI), blood glucose and lipids groups using the chi-square test.Results:The total detection rate of MAFLD and severe MAFLD in the population with a BMI≥28.0 kg/m 2 was 99.6% and 71.8%, respectively. The detection rate of MAFLD in people with normal BMI was 28.4%. The detection rate of MAFLD in women of childbearing age or in the perimenopausal period were both significantly lower than that in men of the same age (40.3% vs 54.9%, χ 2=20.78, P<0.001; 43.1% vs 58.4%, χ 2=27.43, P<0.001), but there was no statistically significant difference in MAFLD detection rate between postmenopausal women and men of the same age. The detection rates of MAFLD in the group with abnormal blood glucose and lipids were both significantly higher than those in the group with normal blood glucose and lipids [69.7%(196/281) vs 35.2%(2 354/6 680), χ 2=138.36, P<0.001; 54.3%(1 696/3 124) vs 37.1%(1 420/3 837), χ 2=207.99, P<0.001]. Conclusion:Non-hepatitis patients had a higher prevalence of MAFLD. The BMI, gender, age, blood glucose, and lipids levels are all strongly associated with MAFLD.

Objective:To summarize the clinical features and survival differences between human immunodeficiency virus (HIV)-positive and HIV-negative cervical cancer patients, and to explore the factors influencing the prognosis.Methods:The clinical data of patients with cervical cancer diagnosed and treated in Zhongnan Hospital of Wuhan University from January 2015 to January 2022 were retrospectively analyzed. There were 46 HIV-positive cases and 587 HIV-negative cases; all 46 HIV-positive patients had squamous cell carcinoma, while 504 HIV-negative patients had squamous cell carcinoma. According to age and clinical staging, 230 HIV-negative squamous cell carcinoma patients were screened to match with 46 HIV-positive squamous cell carcinoma patients according to 1∶5. The clinical features of HIV-positive and HIV-negative patients were compared in all matched patients with pathological type of squamous cell carcinoma; the Kaplan-Meire method was used to analyze the overall survival (OS) and the comparison of OS was made by using log-rank test. Multivariate Cox proportional risk model was used to analyze the independent factors affecting the OS of patients with cervical squamous cell carcinoma.Results:The differences in the age, pathological types, clinical staging between 46 HIV-positive patients and 587 HIV-negative patients were statistically significant (all P < 0.05). There were statistically significant differences in age and clinical staging between 46 HIV-positive squamous cell carcinoma patients and 504 HIV-negative squamous cell carcinoma patients (all P < 0.05). After 1∶5 matching, there were no statistically significant differences in the age, clinical staging between 46 patients with HIV-positive squamous cell carcinoma and 230 patients with HIV-negative squamous cell carcinoma. The OS of HIV-positive patients in the entire group,pathological type of squamous cell carcinoma or after pairing was worse than that of HIV-negative patients (all P < 0.001). The median OS time of HIV-positive patients was 63 months (95% CI 61-109 months), while the median OS time of HIV-negative patients was not reached (95% CI 165-178 months, 164-178 months, 143-173 months, respectively). Multivariate Cox regression analysis showed that clinical staging Ⅲ-Ⅳ was an independent risk factor for OS in patients with cervical squamous cell carcinoma (Ⅲ-Ⅳ vs. Ⅰ-Ⅱ: HR = 1.573, 95% CI 1.032-2.397, P = 0.035); HIV infection was an independent protective factor for OS (HIV-positive vs. HIV-negative: HR = 0.087, 95% CI 0.042-0.182, P < 0.001), indicating that HIV-positive patients had an advantage in OS compared to HIV-negative patients at the same age and clinical staging. Age was not an independent influencing factor for OS ( P > 0.05). Conclusions:The onset age of HIV-positive cervical cancer tends to be younger and the clinical staging is late when patients are diagnosed. HIV-positive patients have poor prognosis.

【Objective】 To explore the efficacy of flexible ureteroscopic lithotripsy (FURL) under local anesthesia (LA) in the treatment of upper urinary tract calculi, and to analyze the risk factors of pain. 【Methods】 Clinical data of 255 patients treated during Apr.2022 and Sep.2022 were reviewed, including visual analogue score (VAS) of pain during ureteroscopy, sheath placement, holmium laser lithotripsy, 1 hour and 8 hours after operation. VAS ≥5 was defined as significant pain. Clinical and follow-up data of the significant pain group and non-significant pain group were analyzed with logistic regression to analyze the risk factors of pain in FURL under LA. 【Results】 Altogether 198 patients (77.6%) successfully completed the operation, and the stone-free rate (SFR) was 89.9% (178/198). The VAS of ureteroscopy was the highest (4.49±1.08), and 73 patients (28.6%) experienced significant pain. Univariate analysis showed that significant pain was associated with gender, previous surgical history, age, body mass index (BMI), education level, and ASA classification (P<0.05). Multivariate analysis showed that male (OR=2.896, 95%CI:1.413-5.933, P=0.040) and BMI≥28 (OR=7.776, 95%CI:2.268-26.657, P=0.001) were independent risk factors of significant pain, while age ≥65 years (OR=0.237, 95%CI:0.083-0.672, P=0.007) and previous surgical history (OR=0.156, 95%CI:0.032-0.754, P=0.021) were the protective factors. 【Conclusion】 It is feasible and effective to treat upper urinary tract calculi with FURL under LA. The presence of significant pain is associated with factors such as gender, age, BMI and previous surgical history.

Objective:To investigate the prevalence of liver fibrosis in patients with HBV infection detected by ultrasound transient elastography.Methods:A total of 2 689 patients with HBV infection who received liver transient elastography examination at the Department of Hepatology, Zhongnan Hospital of Wuhan University from November 2021 to April 2022 were enrolled in the study. The severity of liver fibrosis was graded according to the liver stiffness value. The association of liver fibrosis detection rate with gender, age and physiological stages of patients was analyzed, and the correlation between liver stiffness value and HBV DNA, HBsAg, HBeAg level, alanine aminotransferase (AST), aspartate aminotransferase (ALT) and serum albumin levels was further analyzed.Results:Among 2 689 patients with chronic HBV infection, there were 1 417 males aged 46 (34, 57) years and 1 272 females aged 45 (33, 55) years. A total of 1 382 patients (51.03%) showed varying degrees of liver fibrosis, including 381 cases (14.20%) of significant liver fibrosis and 259 (9.60%) cases of progressive fibrosis. Male patients had a significantly higher prevalence of liver fibrosis than that of female patients [60.78%(840/1 382) vs. 39.22%(542/1 382), χ2=74.566, P<0.001]. There were significant differences in liver stiffness values and liver fibrosis detection rates ( F=46.516, 199.079, P<0.001) among patients of different age groups. The liver stiffness index (9.41±4.49 vs. 8.10±3.89, t=9.011, P<0.001) and the prevalence of liver fibrosis in males was higher than those in females in age groups younger than 60 years [61.59%(643/1 044) vs. 38.41%(401/1 044), χ2=78.418, P<0.001]; However, there was no significant gender difference in people over 60 years of age [73.80%(200/271) vs. 71.71%(142/198), χ2=0.252, P>0.05; 20.30%(55/271) vs. 21.21%(42/198), χ2=0.059, P>0.05]. The prevalence of liver fibrosis was significantly lower in premenopausal and perimenopausal females than that in males of the same age groups [29.70%(188/633)and 52.20%(154/295) vs. 64.50%(202/313), χ 2=56.683, P<0.001; χ 2=9.519, P=0.029], whereas there was no significant difference between postmenopausal females and males in the same age group [65.40%(220/336) vs. 72.20%(319/441), χ 2=5.822, P=0.061]. The prevalence of liver fibrosis increased significantly in postmenopausal females as compared to premenopausal females[38.40%(497/1 294) vs. 67.50%(532/787), χ 2=56.683, P=0.002]. The value of liver stiffness in patients with chronic HBV infection was positively correlated with total bilirubin, AST and ALT levels( r=0.208, 0.227, 0.218, P<0.05). Conclusions:The prevalence of liver fibrosis detected by ultrasound transient elastography in chronic HBV-infected patients is substantial, the liver stiffness value and detection rate are higher in males than those in females, however, the prevalence is increased in postmenopausal females. The liver stifness value is related to some biochemical indicators of the liver.

Objective:To investigate the feasibility, efficacy and adverse reactions of programmed death-1(PD-1) inhibitors in patients with acquired immunodeficiency syndrome (AIDS) complicated with malignant tumor.Methods:From September 2020 to August 2021, patients with AIDS complicated with malignant tumor in Zhongnan Hospital of Wuhan University were enrolled. Data including basic information, laboratory test results, CD4 + T cell count, human immunodeficiency virus (HIV) viral load were collected. Patients were continuously administered intravenously PD-1 monoclonal antibody until disease progression or intolerant toxicity reaction occurred. Adverse reactions during treatment were recorded.And treatment outcomes were assessed once every 12 weeks after treatment. HIV viral load was measured after treatment once a week for four consecutive times, then once four weeks for two consecutive times, and then once every 12 weeks. Results:Ten patients were included in the study, including seven males and three females, three cases of Hodgkin′s lymphoma, two cases of cervical cancer and hepatocellular carcinoma respectively, one case of non-Hodgkin′s lymphoma, non-small cell lung cancer and anal cancer respectively. There were four patients with CD4 + T cell count of 100 to 200 cells/μL and two patients with CD4 + T cell count lower than 100 cells/μL. All patients had completed at least three cycles of treatment with PD-1 monoclonal antibody, HIV viral load remained lower than 20 copies /mL. Three cases achieved complete response and three cases achieved partial response. Adverse reactions were cutaneous capillary endothelial proliferation (CCEP) (seven cases), major bleeding (three cases), and hearing impairment (one case). Conclusions:PD-1 inhibitor has no adverse effect on the continuous suppression of HIV viral load and has an effect on tumor control, so it is a viable choice in AIDS patients complicated with tumor. However, due to its considerable adverse reactions, multidisciplinary cooperation is needed to reduce the risk of complications and deal with serious complications.

Gastric cancer (GC) is known as a top malignant type of tumors worldwide. Despite the recent decrease in mortality rates, the prognosis remains poor. Therefore, it is necessary to find novel biomarkers with early diagnostic value for GC. In this study, we present a large-scale proteomic analysis of 30 GC tissues and 30 matched healthy tissues using label-free global proteome profiling. Our results identified 537 differentially expressed proteins, including 280 upregulated and 257 downregulated pro-teins. The ingenuity pathway analysis (IPA) results indicated that the sirtuin signaling pathway was the most activated pathway in GC tissues whereas oxidative phosphorylation was the most inhibited. More-over, the most activated molecular function was cellular movement, including tissue invasion by tumor cell lines. Based on IPA results, 15 hub proteins were screened. Using the receiver operating character-istic curve, most of hub proteins showed a high diagnostic power in distinguishing between tumors and healthy controls. A four-protein (ATP5B-ATP5O-NDUFB4-NDUFB8) diagnostic signature was built using a random forest model. The area under the curve (AUC) values of this model were 0.996 and 0.886 for the training and testing sets, respectively, suggesting that the four-protein signature has a high diag-nostic power. This signature was further tested with independent datasets using plasma enzyme-linked immune sorbent assays, resulting in an AUC value of 0.778 for distinguishing GC tissues from healthy controls, and using immunohistochemical tissue microarray analysis, resulting in an AUC value of 0.805. In conclusion, this study identifies potential biomarkers and improves our understanding of the pathogenesis, providing novel therapeutic targets for GC.
