Objective: To systematically evaluate the incidence and influencing factors of depression in family caregivers of Alzheimer's disease (AD) patients, so as to provide the basis for the prevention and treatment of depression among the family caregivers of AD patients. Methods: Publications pertaining to depression in family caregivers of AD patients were retrieved from CNKI, Wanfang Data, PubMed and other databases from the time of their establishment to June 15, 2023. The evaluation criteria recommended by the Agency for Healthcare Research and Quality (AHRQ) and the Newcastle-Ottawa Scale were used to assess the quality of cross-sectional and cohort studies, respectively. Stata 16.0 and Revman 5.4 softwares were used to conduct a meta-analysis on the incidence and influencing factors of depression in family caregivers of AD patients. Sensitivity analysis and publication bias assessment were also performed on the results. Results: A total of 2 324 articles were retrieved, and ultimately 14 articles were included, with a total sample size of 8 313 individuals. There were 6 high-quality articles and 8 moderate-quality articles. Meta-analysis showed that the incidence of depression in family caregivers of AD patients was 37.5% (95%CI: 30.2%-45.1%). Factors associated with depression included patients' high degree of dementia (OR=1.718, 95%CI: 1.059-2.789), patients' low scores on Activities of Daily Living Scale (OR=1.344, 95%CI: 1.059-1.706), patients' psychobehavioral abnormalities (OR=1.248, 95%CI: 1.155-1.348), long duration of caregiving (OR=1.998, 95%CI: 1.637-2.437), less involvement of other family members in caregiving (OR=1.597, 95%CI: 1.237-2.061), low educational level (OR=1.191, 95%CI: 1.044-1.359), poor caregiving skills (OR=3.060, 95%CI: 2.257-4.149), poor self-rated health (OR=2.536, 95%CI: 1.114-5.771) and social support (OR=0.424, 95%CI: 0.232-0.774). The results of depression incidence demonstrated good stability with no significant publication bias. However, publication bias was observed in the influencing factors for depression, which were patients' high degree of dementia and patients' low scores on Activities of Daily Living Scale. Conclusions The incidence of depression in family caregivers of AD patients ranges from 30.2% to 45.1%. It is primarily influenced by the severity of patients' symptoms and ability to perform daily activities, and caregivers' educational level, caregiving skills, health status, caregiving duration and social support.

Objective To explore the value of dynamic ultrasound combined with 3.0T MRI for diagnosing and typing synovial plica of knee joint.Methods Dynamic ultrasound and 3.0T MRI data of 100 patients with suspected synovial plica of knee joint were retrospectively analyzed.Taking the results of arthroscopy as standards,the efficacy of dynamic ultrasound and 3.0T MRI alone and their combination for diagnosing synovial plica of knee joint were evaluated and compared.The length and thickness of synovial plica of knee joint measured with dynamic ultrasound,3.0T MRI alone and their combination were compared with those of arthroscopy,and the consistencies of the location and classification of synovial plica of knee joint with arthroscopy were analyzed.Results Synovial plica was detected in 70 cases,including 11 cases of supropatellar synovial plica,15 cases of infrapatellar synovial plica,medial patellar in 30 cases and lateral patellar synovial plica in 14 cases,among them type A,B,C and D were classified in 9,35,23 and 3 cases,respectively.No significant difference of sensitivity was found between dynamic ultrasound and 3.0T MRI alone for diagnosing synovial plica of knee joint(P＞0.05),which were both lower than that of their combination(both P＜0.05).The length and thickness of knee synovial plica measured with dynamic ultrasound and 3.0T MRI alone were lower than those measured with their combination and arthroscopy(all P＜0.05),and there was no significant difference between the results of their combination and arthroscopy(both P＞0.05).Dynamic ultrasound,3.0T MRI alone and their combination had high consistency of location(Kappa=0.755,0.826,0.897)and classification of knee synovial plica with those of arthroscopy(Kappa=0.721,0.744,0.860).Conclusion Dynamic ultrasound combined with 3.0T MRI was valuable for diagnosing and typing of synovial plica of knee joint.

Objective To observe the clinical efficacy of neck-shoulder-waist-leg pain cataplasms combined with electroacupuncture in the treatment of acute cervical radiculopathy(CR)with qi stagnation and blood stasis syndrome;To evaluate the synergistic effect and safety of neck-shoulder-waist-leg pain cataplasms.Methods Totally 132 CR patients with qi stagnation and blood stasis type in acute stage were randomly divided into treatment group(66 cases)and control group(66 cases).The treatment group was treated with electroacupuncture combined with neck-shoulder-waist-leg pain cataplasms,and the control group was treated with electroacupuncture combined with placebo.Both groups were treated once a day for 5 days and then rested for 2 days for 3 weeks,and follow-up was performed at 1 and 2 weeks after treatment.Clinical efficacy of both groups was observed.The short-form McGill pain questionnaire(SF-MPQ)score,neck disability index(NDI)score,and the F-wave conduction velocity of the median nerve and ulnar nerve were compared before and after treatment and at follow-up.Results 5 and 7 cases were lost in the treatment group and the control group,respectively.The total effective rate of the treatment group was 91.80%(56/61),and the recovery rate was 36.07%(22/61).The total effective rate of the control group was 84.75%(50/59),and the recovery rate was 18.65%(11/59).The difference in recovery rates between the two groups was statistically significant(P<0.05).Compared with before treatment,the SF-MPQ score and NDI score in both groups improved significantly(P<0.05)after treatment and at 1 and 2 weeks of follow-up,and the F-wave conduction velocity of the median and ulnar nerves increased significantly(P<0.05)after treatment.Comparison between two groups at the same time points showed that the SF-MPQ score and NDI score of the treatment group were better than those of the control group(P<0.05)after treatment and at 1 and 2 weeks of follow-up,and the F-wave conduction velocity of the median and ulnar nerves was faster than that of the control group(P<0.05)after treatment.There were no serious adverse reactions in the two groups.Conclusion Neck-shoulder-waist-leg pain cataplasms combined with electroacupuncture can improve the clinical symptoms of CR with qi stagnation and blood stasis syndrome in acute stage.Electroacupuncture plus neck-shoulder-waist-leg pain cataplasms can speed up the recovery process of the disease,which has synergistic effect.

Objective Idiopathic non-cirrhotic portal hypertension (INCPH) is a rare cause of portal hypertension, and this study aims to analyze the clinical features of patients with INCPH, and to assist in diagnosis and differential diagnosis. Methods A total of 74 patients who were hospitalized in Beijing YouAn Hospital from January 2019 to July 2022 and were diagnosed with INCPH were enrolled, and 332 patients with liver cirrhosis who were hospitalized during the same period of time were enrolled as control group. Demographic data, laboratory markers, gastroscopy, liver elasticity, pathological examination, and complications were recorded and compared between the two groups. The receiver operating characteristic (ROC) curve was used to investigate the ability of liver stiffness measurement (LSM), aspartate aminotransferase-to-platelet ratio index (APRI), and fibrosis-4 (FIB-4) in the differential diagnosis of INCPH, and the DeLong test was used to compare the area under the ROC curve (AUC). The independent-samples t test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. Results Among the patients with INCPH, 46.55% had no obvious symptoms at disease onset and 43.24% were misdiagnosed with liver cirrhosis. Compared with the patients with liver cirrhosis, the patients with INCPH had a significantly higher proportion of patients with gastrointestinal bleeding (62.16% vs 41.27%, χ 2 =10.67, P < 0.01) and a significantly lower proportion of patients with moderate-to-severe ascites (16.21% vs 29.82%, χ 2 =34.98, P < 0.01), and there were few patients with hepatic encephalopathy. As for pathology, 89.19% (66/74) of the INCPH patients manifested as typical occlusive portal vein disease. The statistical analysis showed that compared with the patients with liver cirrhosis, the patients with INCPH had significantly better liver function parameters, MELD score, and Child-Pugh score and significantly lower LSM [9.05(7.18-12.33) vs 25.32(16.21-47.23), Z =-8.41, P < 0.01], APRI score [0.70(0.41-1.28) vs 1.35(0.80-2.39), Z =-6.21, P < 0.01], and FIB-4 index [2.99(1.62-4.81) vs 6.68(4.06-10.42), Z =-8.39, P < 0.01]. LSM, FIB-4, and APRI had a good ability in differentiating INCPH from liver cirrhosis, and in particular, LSM had an AUC of up to 0.92 (95% confidence interval: 0.87-0.96), with a sensitivity of 92.68% and a specificity of 81.60%. Conclusion INCPH patients tend to have an insidious onset, a relatively high incidence rate of portal hypertension-related complications, and relatively good liver function, especially the patients with LSM < 14.5 kPa. The possibility of INCPH should be considered for such patients in clinical practice.

Increasing evidences suggest the important role of calcium homeostasis in hallmarks of cancer, but its function and regulatory network in metastasis remain unclear. A comprehensive investigation of key regulators in cancer metastasis is urgently needed. Transcriptome sequencing (RNA-seq) of primary esophageal squamous cell carcinoma (ESCC) and matched metastatic tissues and a series of gain/loss-of-function experiments identified potassium channel tetramerization domain containing 4 (KCTD4) as a driver of cancer metastasis. KCTD4 expression was found upregulated in metastatic ESCC. High KCTD4 expression is associated with poor prognosis in patients with ESCC and contributes to cancer metastasis in vitro and in vivo. Mechanistically, KCTD4 binds to CLIC1 and disrupts its dimerization, thus increasing intracellular Ca²⁺ level to enhance NFATc1-dependent fibronectin transcription. KCTD4-induced fibronectin secretion activates fibroblasts in a paracrine manner, which in turn promotes cancer cell invasion via MMP24 signaling as positive feedback. Furthermore, a lead compound K279-0738 significantly suppresses cancer metastasis by targeting the KCTD4‒CLIC1 interaction, providing a potential therapeutic strategy. Taken together, our study not only uncovers KCTD4 as a regulator of calcium homeostasis, but also reveals KCTD4/CLIC1-Ca²⁺-NFATc1-fibronectin signaling as a novel mechanism of cancer metastasis. These findings validate KCTD4 as a potential prognostic biomarker and therapeutic target for ESCC.

Enzalutamide (ENZ) is a second-generation androgen receptor (AR) antagonist used for the treatment of castration-resistant prostate cancer (CRPC) and reportedly prolongs survival time within a year of starting therapy. However, CRPC patients can develop ENZ resistance (ENZR), mainly driven by abnormal reactivation of AR signaling, involving increased expression of the full-length AR (ARfl) or dominantly active androgen receptor splice variant 7 (ARv7) and ARfl/ARv7 heterodimers. There is currently no efficient treatment for ENZR in CRPC. Herein, a small molecule LLU-206 was rationally designed based on the ENZ structure and exhibited potent inhibition of both ARfl and constitutively active ARv7 to inhibit PCa proliferation and suppress ENZR in CRPC. Mechanically, LLU-206 promoted ARfl/ARv7 protein degradation and decreased ARfl/ARv7 heterodimers through mouse double minute 2-mediated ubiquitination. Finally, LLU-206 exhibited favorable pharmacokinetic properties with poor permeability across the blood-brain barrier, leading to a lower prevalence of adverse effects, including seizure and neurotoxicity, than ENZ-based therapies. In a nutshell, our findings demonstrated that LLU-206 could effectively inhibit ARfl/ARv7-driven CRPC by dual-targeting of ARfl/ARv7 heterodimers and protein degradation, providing new insights for the design of new-generation AR inhibitors to overcome ARfl/ARv7-driven CRPC.

OBJECTIVE To study the sp ectrum-effect relationship of anti-gastric ulcer effect of Shaoyao gancao decoction. METHODS Eleven batches of Shaoyao gancao decoction were prepared ；gastric ulcer model was established by anhydrous ethanol modeling method. Using Weikangling as positive control ，the effects of Shaoyao gancao decoction on the contents of defensive factors [nitric oxide （NO），epidermal growth factor （EGF），superoxide dismutase （SOD）] and attack factor [malondialdehyde （MDA）] in gastric tissue of model rats were investigated. HPLC fingerprints of 11 batches of Shaoyao gancao decoction were established and similarity evaluation was performed with Similarity Evaluation System of Traditional Chinese Medicine Chromatographic Fingerprint （2004A edition ）； common peaks were identified by comparing with mixed control. The spectrum-effect relationship of Shaoyao gancao decoction against gastric ulcer was analyzed based on the grey correlation analysis. RESULTS Eleven batches of Shaoyao ganyao decoction could significantly decrease the content of MDA in gastric tissue ，while increased the contents of NO ，EGF and SOD in gastric ulcer model rats （P＜0.01），and had a certain inhibitory effect on the gastric ulcer. There were 23 common peaks in chromatograms of 11 batches of samples ，and the similarity with the control fingerprint was not less than 0.9. By comparing with mixed control ，7 common peaks were identified ，namely gallic acid （peak 5），albiflorin（peak 9），paeoniflorin（peak 10），liquiritin（peak 12），isoliquiritin apioside （peak 14），isoliquiritoside（peak 15）， glycyrrhizic acid （peak 22）. The average correlation degree of 7 identified common peaks and pharmacodynamic indexes were greater than 0.6，of which peak 22（glycyrrhizic acid ），peak 10（paeoniflorin）and peak 12（liquiritin）had the largest correlation ， and their values were 0.807，0.772 and 0.770 respectively. RESULTS The anti-gastric ulcer effect of Shaoyao gancao decoction is the result of the synergistic effect of multiple components ，among which glycyrrhizic acid ，paeoniflorin and liquiritin may be the main pharmacodynamic components.

Objective:To study the correlation between the acute-phase characteristics of motor evoked potential (MEP) and severities of spinal cord injury in patients with acute cervical hyperextension injury and central cord syndrome (CCS).Methods:Retrospectively analyzed were the data of 45 patients with acute cervical hyperextension injury and CCS (observation group) who had been admitted to Department of Orthopedics, Tongji Hospital Affiliated to Tongji University from December 2018 to July 2021 and 20 healthy controls. Examination of transcranial magnetic stimulation-induced MEP was performed in patients with CCS and healthy controls using a magpro x100 magnetic stimulator, and recording was conducted in bilateral abductor pollicis brevis (APB). The characteristics of MEP waveform latency, amplitude and motor threshold were described and compared between the healthy control and observation groups; the correlations were analyzed between the MEP latency and the severity of spinal cord injury [American Spinal Injury Association (ASIA) total score and motor function of Upper Extremity Motor Subscores (UEMS)] in the observation group. According to different MEP-induced states, the patients in the observation group were divided into a resting group ( n=19), a facilitation group ( n=18), and a no-waveform group ( n=8). The severity of spinal cord injury (ASIA total score) and the functional independence of the spinal cord (SCIM-Ⅲ score) were compared among the 3 groups to analyze the correlation between the MEP-induced state and the severity of spinal cord injury (ASIA total score). Results:The observation group had a significantly longer MEP latency [(30.16±6.32) ms], a significantly smaller amplitude [(0.54±0.30) mV] and a significantly higher motor threshold [(65%±11%)] than the healthy control group (all P<0.05). The MEP latency in the observation group was significantly correlated with ASIA total score ( r=-0.730, P<0.001) and UEMS ( r=-0.740, P<0.001). The ASIA total score and SCIM-Ⅲ score were significantly different among the 3 groups ( P<0.05), and the MEP-induced state was significantly correlated with the severity of spinal cord injury (ASIA total score) ( r=0.668, P<0.001). Conclusions:In patients with acute cervical hyperextension injury and CCS, the MEP latency is prolonged, the amplitude lowered, and the motor threshold enhanced. The MEP latency is strongly correlated with the severity of spinal cord injury and upper limb motor function. The MEP-induced state is also closely related to the severity of spinal cord injury.

AIM: To explore the effect of Huatanjiangqi capsule medicated serum (HTJQ) on the resistance of human bronchial epithelial cells (16HBE) to glucocorticoid (GC) stimulated by cigarette smoke extract (CSE). METHODS: After 16HBE cells were treated with HTJQ, the effects of different concentrations of HTJQ on the viability of 16HBE cells were determined by CCK-8 method. 16HBE cells were pretreated with HTJQ, and then cultured with dexamethasone (DEX) and lipopolysaccharide (LPS) for 24 hours, the effect of HTJQ on glucocorticoid (GC) resistance of 16HBE cells was determined by Enzyme-linked immunosorbent assay (ELISA). The effects of HTJQ, sulforaphane (SFN) and glutathione (GSH) on the expression of NF-E2-related factors 2 (Nrf2), Heme oxygenase-1 (HO-1) and histone deacetylase 2 (HDAC2) in 16HBE cells stimulated by CSE were measured by Western blot, and the effects of HTJQ, SFN and GSH on interleukin-8 (IL-8) in 16HBE cells were measured by ELISA. RESULTS: HTJQ promoted the proliferation of 16HBE cells at 1 h, 2 h and 4 h, the results of ELISA and Western blot showed that CSE induced GC resistance and decreased the expression of Nrf2, HO-1 and HDAC2 in 16HBE cells, HTJQ significantly decreased IL-8 and improved GC sensitivity of 16HBE cells (P<0.01), and up-regulated the expression of Nrf2, HO-1 and HDAC2 (P<0.01). In addition, HTJQ significantly up-regulated the level of GSH in 16HBE cells (P<0.01). Nrf2 agonists SFN and GSH significantly improved the glucocorticoid sensitivity of 16HBE cells (P<0.01), and up-regulated the expression of Nrf2, HO-1 and HDAC2 (P<0.01). CONCLUSION: HTJQ improves the GC resistance of 16HBE cells by up-regulating the expression of Nrf2/HDAC2 protein and the level of intracellular GSH.
