Objective:To evaluate the safety and efficacy of ultrasound-guided percutaneous negative pressure suction and minimally invasive rotatory excision technique for the treatment of complex encapsulated lesions.Methods:A total of 48 patients(48 lesions) with complex encapsulated lesions who underwent ultrasound-guided percutaneous negative pressure suction and minimally invasive rotatory excision technique at Xi′an Chest Hospital from January to October 2023 were retrospectively enrolled, including 39 cases of encapsulated abscess, 7 cases of encapsulated effusion, and 2 cases of encapsulated haematoma; the distribution of the bacterial flora of the abscesses were as follows: 24 cases of tuberculous abscess, 14 cases of bacterial abscess, 1 case of bacterial combined bacterial-fungal abscess, and 7 cases of encapsulated effusion were tuberculous pleurisy, and the clinical data were analysed retrospectively. The maximum upper and lower diameters, right and left diameters, and anterior and posterior diameters of the lesions were measured by ultrasound before and after the operation. The patients′ various biochemical indicators (C-reactive protein, white blood cell count, neutrophil count, erythrocyte sedimentation rate) were detected. The intraoperative and postoperative complications, postoperative outcomes, and postoperative clinical symptoms were recorded.Results:Of the 48 patients, 39 were cured and discharged after negative pressure suction and rotatory excision technique, and 9 patients were cured and discharged after surgical incision and drainage of the lesions. The overall effective rate of negative pressure suction and rotatory excision treatment reached 81.25%, and the average number of days of tube placement was (11.81±7.22) days, and the average number of days of follow-up was (35.77±19.39) days. Compared with preoperative values, the upper and lower diameters, the left and right diameters, and the anterior and posterior diameters of the lesions were all reduced after operation [5.80 (4.95, 7.95)cm vs 8.00 (6.00, 11.82)cm, 4.00 (3.25, 5.00)cm vs 5.85 (4.52, 7.65)cm, 1.80 (1.00, 2.90)cm vs 3.40 (2.50, 6.15)cm, all P<0.01]; and postoperative C-reactive protein, white blood cell count and neutrophil count all decreased (all P<0.05). Before operation there were 31 cases of local swelling, 16 cases of pain, 12 cases of activity limitation, 12 cases of fever, 7 cases of chest tightness, and 6 cases of shortness of breath, and during postoperative follow-up, there were 4 cases of local swelling, 5 cases of pain, and 4 cases of activity limitation. The symptoms of fever, chest tightness, and shortness of breath all disappeared, and there was a statistically significant difference between preoperation and postoperation (all P<0.05). There were no adverse events or complications associated with the intraoperative and postoperative follow-up of negative pressure suction and rotatory excision treatment. Conclusions:Ultrasound-guided percutaneous negative pressure suction and invasive rotatory excision technique for the treatment of complex encapsulated lesions can significantly reduce lesion size, reduce inflammatory response and improve patient symptoms, which is a safe, effective and minimally invasive technique.

BACKGROUND: Patients with atrial fibrillation (AF) and prior stroke history have a high risk of cardiovascular events despite anticoagulation therapy. It is unclear whether catheter ablation (CA) has further benefits in these patients. METHODS: AF patients with a previous history of stroke or systemic embolism (SE) from the prospective Chinese Atrial Fibrillation Registry study between August 2011 and December 2020 were included in the analysis. Patients were matched in a 1:1 ratio to CA or medical treatment (MT) based on propensity score. The primary outcome was a composite of all-cause death or ischemic stroke (IS)/SE. RESULTS: During a total of 4.1 ± 2.3 years of follow-up, the primary outcome occurred in 111 patients in the CA group (3.3 per 100 person-years) and in 229 patients in the MT group (5.7 per 100 person-years). The CA group had a lower risk of the primary outcome compared to the MT group [hazard ratio (HR) = 0.59, 95% CI: 0.47-0.74, P < 0.001]. There was a significant decreasing risk of all-cause mortality (HR = 0.43, 95% CI: 0.31-0.61, P < 0.001), IS/SE (HR = 0.73, 95% CI: 0.54-0.97, P = 0.033), cardiovascular mortality (HR = 0.32, 95% CI: 0.19-0.54, P < 0.001) and AF recurrence (HR = 0.33, 95% CI: 0.30-0.37, P < 0.001) in the CA group compared to that in the MT group. Sensitivity analysis generated consistent results when adjusting for time-dependent usage of anticoagulants. CONCLUSIONS In AF patients with a prior stroke history, CA was associated with a lower combined risk of all-cause death or IS/SE. Further clinical trials are warranted to confirm the benefits of CA in these patients.

The cGAS-STING signaling pathway is one of the main pathways of immune defense against many types of pathogens. cGAS catalyzes the production of the second messenger cGAMP (cyclic GMP-tVMP) by recognizing plasma DNA and cGAMP subsequently binds to the interferon gene stimulating factor (STING). The pathway induces the production of type I interferon (IFN-I) and activates the innate immune system. The activation of the cGAS-STI]NG pathway could facilitate self-protection,thus STI]NG agonists for tumor immunotherapy have attracted much attention in recent years,and several drug candidates have been in clinical trials. Meanwhile,aberrant activation of cGAS-STI]NG could lead to autoimmune diseases and has attracted extensive interest in developing its inhibitors. This paper summarizes the mechanism and regulatory sites of the cGAS-STI]NG pathway,and outlines the research progress of cGAS-STING pathway-related immune and inflammatory diseases and its inhibitors.

Abstract: Objective To understand the mental health literacy level of residents in Hainan Province, and to provide evidence for promoting mental health promotion and improving the mental health literacy level of residents. Methods Multi-stage random sampling method was used to investigate The National Mental Health Literacy Questionnaire among 6 895 residents in 12 districts including Changjiang, Chengmai, Dongfang, Ledong, Lingshui, Haikou Longhua District, Haikou Meilan District, Qionghai, Sanya, Tunchang, Wenchang and Wuzhishan. Results　In the survey 6 895 residents in 12 counties, cities, districts of Hainan Province, 365 of them reached the standard of mental health with the standard rate of 5.3%. The mental health knowledge score was (54.00±17.02) with the standard rate of 7.7%; the self-assessment score was (26.11±3.99) with the standard rate of 75.9%; the score of mental health skill was (26.22±7.25) with the standard rate of 44.8%. The mental health literacy level of medical workers was the highest, with the standard rate of 13.5% (112/830), and the mental health literacy level of farmers was the lowest, with the standard rate of 0.8% (13/1 647). The results of unconditional Logistic regression showed that the factors entering the regression model included educational background (OR=2.268), personal monthly income (OR=1.129), gender (OR=1.302), household registration (OR=0.776), and whether they had participated in mental health related courses OR training (OR=0.511). The higher the educational background and personal monthly income, the higher the psychological quality. The mental health of women was higher than that of men, and that of urban was higher than that of rural, and those who had participated in mental health related courses were higher than those who had not. Conclusions The mental health literacy level of Hainan residents is at a low level, and the influencing factors are multifaceted. It is suggested to strengthen the mental health monitoring comprehensively and carry out rich health education service mode for different groups.

OBJECTIVE: To observe the effect of electroacupuncture (EA) on vascular endothelial growth factor-C (VEGF-C), vascular endothelial growth factor receptor-3 (VEGFR-3), proinflammatory factors and apoptosis in myocardial tissue in mice with acute myocardial ischemia (AMI), and to explore the mechanism of EA for AMI. METHODS: Fifty male C57BL/6 mice were randomly divided into a sham operation group, a model group, an EA group, an inhibitor group and an inhibitor+EA group, 10 mice in each group. Except for the sham operation group, the mice in the remaining groups were intervented with ligation at the left anterior descending (LAD) coronary artery to establish AMI model. The mice in the sham operation group were intervented without ligation after thoracotomy. The mice in the EA group were intervented with EA at "Shenmen" (HT 7) and "Tongli" (HT 5), disperse-dense wave, 2 Hz/15 Hz in frequency, 1 mA in current intensity, 30 min each time, once a day, for 3 d. The mice in the inhibitor group were treated with intraperitoneal injection of SAR 131675 (12.5 mg•kg^-1•d^-1, once a day for 3 d). The mice in the inhibitor+EA group were injected intraperitoneally with SAR 131675 30 min before EA. The ECG before modeling, 30 min after modeling and 3 d after intervention was detected, and the ST segment displacement was recorded; after the intervention, the ELISA method was applied to measure the contents of serum creatine kinase isoenzyme (CK-MB), aspartate aminotransferase (AST) as well as tumor necrosis factor-α (TNF-α) and interleukin-23 (IL-23) in myocardial tissue; the HE staining method was used to observe the morphological changes of myocardial tissue; the immunofluorescence double labeling method was applied to measure the number of co-expression positive cells of VEGF-C/VEGFR-3 in myocardial tissue; the TUNEL method was used to detect the level of cardiomyocyte apoptosis; the Western blot method was applied to measure the protein expressions of VEGF-C, VEGFR-3, b-lymphoma-2 (Bcl-2), activated caspase-3 (Cleaved Caspase-3) and activated poly adenosine diphosphate ribose polymerase-1 (Cleaved PARP-1). RESULTS: Compared with the sham operation group, in the model group the ST segment displacement was increased (P<0.01); the contents of CK-MB, AST, TNF-α and IL-23 were increased (P<0.01); the arrangement of myocardial fibers was disordered, and interstitial inflammatory cell infiltration was obvious; the number of co-expression positive cells of VEGF-C/VEGFR-3 was decreased (P<0.01); the number of cardiomyocyte apoptosis was increased (P<0.01); the expressions of VEGF-C, VEGFR-3 and Bcl-2 were decreased (P<0.01); the expressions of Cleaved Caspase-3 and Cleaved PARP-1 were increased (P<0.01). Compared with the model group, in the EA group the ST segment displacement was decreased (P<0.01); the contents of CK-MB, AST, TNF-α, IL-23 were decreased (P<0.01); the severity of myocardial pathological injury was reduced; the number of co-expression positive cells of VEGF-C/VEGFR-3 was increased (P<0.01); the number of cardiomyocyte apoptosis was reduced (P<0.01); the expressions of VEGF-C, VEGFR-3 and Bcl-2 were increased (P<0.01); the expressions of Cleaved Caspase-3 and Cleaved PARP-1 were reduced (P<0.01). There was no significant difference in all the indexes between the model group and the inhibitor group (P>0.05). Compared with the model group, the protein expression of VEGF-C was increased in the inhibitor+EA group (P<0.01). Compared with the inhibitor group, in the EA group the ST segment displacement was decreased (P<0.01); the contents of CK-MB, AST, TNF-α, IL-23 were decreased (P<0.01); the severity of myocardial pathological injury was reduced; the number of co-expression positive cells of VEGF-C/VEGFR-3 was increased (P<0.05); the number of cardiomyocyte apoptosis was reduced (P<0.01); the expressions of VEGF-C, VEGFR-3 and Bcl-2 were increased (P<0.01); the expressions of Cleaved Caspase-3 and Cleaved PARP-1 were reduced (P<0.01). Compared with the inhibitor+EA group, all the indexes in the EA group were improved except the protein expression of VEGF-C (P<0.01). CONCLUSION EA could relieve the inflammatory reaction and apoptosis in AMI mice, and its mechanism may be related to activating VEGF-C/VEGFR-3 pathway and promoting lymphangion genesis.

Objective: To explore the relationship between fasting blood glucose level and thromboembolism events in patients with non-valvular atrial fibrillation (NVAF). Methods: This was an observational study based on data from a multicenter, prospective Chinese atrial fibrillation registry cohort, which included 18 703 consecutive patients with atrial fibrillation (AF) in 31 hospitals in Beijing from August 2011 to December 2018. Patients were divided into 5 groups according to status of comorbid diabetes and fasting glucose levels at admission: normal blood glucose (normal glucose group), pre-diabetes group, strict glycemic control group, average glycemic control group and poor glycemic control group. Patients were followed up by telephone or outpatient service every 6 months. The primary follow-up endpoint was thromboembolic events, including ischemic stroke and systemic embolism. The secondary endpoint was the composite endpoint of cardiovascular death and thromboembolic events. Kaplan-Meier survival analysis and multifactorial Cox regression were used to analyze the correlation between fasting glucose levels and endpoint events. Results: The age of 18 703 patients with NVAF was (63.8±12.0) years, and there were 11 503 (61.5%) male patients. There were 11 877 patients (63.5%) in normal blood glucose group, 2 023 patients (10.8%)in pre-diabetes group, 1 131 patients (6.0%) in strict glycemic control group, 811 patients in average glycemic control group and 2 861 patients(4.3%) in poor glycemic control group. Of the 4 803 diabetic patients, 1 131 patients (23.5%) achieved strict glycemic control, of whom 328 (29.0%) were hypoglycemic (fasting blood glucose level<4.4 mmol/L at admission). During a mean follow-up of (51±23) months (up to 82 months), thromboembolic events were reported in 984 patients (5.3%). The survival curve analysis of Kaplan Meier showed that the incidence rates of thromboembolic events in normal glucose group, pre-diabetes group, strict glycemic control group, average glycemic control group and poor glycemic control group were 1.10/100, 1.41/100, 2.09/100, 1.46/100 and 1.71/100 person-years, respectively (χ²=53.0, log-rank P<0.001). The incidence rates of composite endpoint events were 1.86/100, 2.17/100, 4.08/100, 2.58/100, 3.16/100 person-years (χ²=72.3, log-rank P<0.001). The incidence of thromboembolic events and composite endpoint events in the other four groups were higher than that in the normal blood glucose group (P<0.001). Multivariate Cox regression analysis showed that compared with normal glucose group, the risk of thromboembolism increased in pre-diabetes group(HR=1.23, 95%CI 1.00-1.51, P=0.049), strict glycemic control group(HR=1.32, 95%CI 1.06-1.65, P=0.013) and poor glycemic control group(HR=1.26, 95%CI 1.01-1.58, P=0.044). Conclusion: Both high or low fasting glucose may be an independent risk factor for thromboembolic events in patients with NVAF.

Objective To understand the distribution of Oncomelania hupensis snails and changes of water levels in Gaoyou sections of the Li Canal following the operation of the eastern route project of the South-to-North Water Diversion Project. Methods The Oncomelania snails were monitored in the river banks and water bodies of Gaoyou sections of the Li Canal by means of systematic sampling combined with environmental sampling as well as collection of the floaters from 2014 to 2019, and the water levels were collected in Gaoyou sections of the Li Canal at the typical hydrological year before the operation of the eastern route project of the South-to-North Water Diversion Project and during the period between 2016 and 2019. Results A total area of 235.42 hm² were investigated and a total of 75.8 kg floaters were collected in Gaoyou sections of the Li Canal from 2014 to 2019; however, no snails were found. The water level in Gaoyou sections of the Li Canal was predominantly high in the flood season and low in the dry season before the operation of the eastern route project of the South-to-North Water Diversion Project, and the water level was elevated in the dry season and relatively low in the flood season after the operation of the project. Conclusion Following the operation of the eastern route project of the South-to-North Water Diversion Project, the original river bank that is characterized by “land in winter and water in summer” has changed in Gaoyou sections of the Li Canal, which is not favorable for snail breeding.

Autoimmune thyroid disease （AITD） is a complex organ-specific autoimmune disease， associated with many factors such as genetic susceptibility， environmental factors， immune system disorders， and intestinal microbiota imbalance， which seriously affect the quality of life. At present， oral medicine， iodine 131 treatment and surgical treatment are mainly adopted in clinical parctice of western medicine. Although they can exert a certain curative effect， they still have surgical risks and side effect. Modern research shows that， traditional Chinese medicine（TCM） has the characteristics of stable curative effect， multi-targeted regulation and less side effect. It has definite efficacy and unique advantages in the prevention and treatment of AITD. Helper T lymphocyte cell 17 （Th17） mediate inflammation to induce immune promotion， while regulatory T lymphocyte cell （Treg） mediate immunosuppression， Th17 and Treg cooperate to maintain the balance of the immune microenvironment. During AITD progress， Inflammatory Th17 can be high， and the levels of mediated immunosuppressive Treg are relatively decreased. The restoration of balance between the two plays a key role in the inflammatory and immune processes of AITD. In recent years， based on Th17/Treg cell axis， a large number of clinical and experimental studies on the intervention of TCM on Th17/Treg balance in AITD have been carried out in the field of TCM， and some results have been achieved. Studies have shown that intervention in the Th17/Treg signaling axis is an important mechanism for the treatment of autoimmune thyroid diseases. This paper summarizes and analyzes the previous studies on the intervention effect of Chinese medicine monomer， Chinese medicine composition and Chinese medicine compound on Th17/Treg cell axis in AITD， mainly from the aspects of intervention related inflammatory factor secretion， regulation of antibody titer and the expression of related genes of related genes. These studies will help people to understand the mechanism of TCM in interfering with the Th17/Treg balance in AITD more accurately and comprehensively， and provide references for the rational application of TCM in the prevention and treatment of autoimmune thyroid diseases in clinical practice.

Objective: To explore the feasibility and safety of intracardiac ultrasound-assisted atrial septal puncture (ASP) during radiofrequency ablation for atrial fibrillation. Methods: We enrolled 241 consecutive patients scheduled to radiofrequency ablation for atrial fibrillation in Beijing Anzhen Hospital from July to September 2020. Inclusion criteria: patients aged over 18 years with a clear electrocardiogram record of atrial fibrillation. Patients were divided into 2 groups: ASP with ultrasound-assisted X-ray (ultrasound group, n=123), ASP under X-ray alone (X-ray group, n=118). Clinical features of patients including age, sex, percent of paroxysmal atrial fibrillation, and repeat ablation, CHA₂DS₂-VASc score and past history (hypertension, diabetes mellitus, coronary artery disease, stroke/transient ischemic attack (TIA), valve diseases) and echocardiographic parameters (left atrial dimension, left ventricular ejection fraction, left ventricular end-diastolic dimension) were obtained and compared. The first-pass rate, radiation exposure time, duration of ASP, and complications of ASP were also compared between the two groups. Results: The age of patients in this cohort was (62.5±8.0) years, and the proportion of males was 57.0% (n=138). Among them, the proportion of paroxysmal atrial fibrillation was 56.0% (n=135), and the ratio of repeat ablation was 17.8% (n=43). Age, sex, percent of paroxysmal atrial fibrillation, history of hypertension, diabetes mellitus were similar between the two groups. The first-pass rate was significantly higher in the ultrasound group than in the X-ray group (94.3% (116/123) vs. 79.7% (94/118), P=0.001); the exposure time of X-ray was significantly shorter in the ultrasound group than in the X-ray group ((31.3±7.9) s vs. (124.8±35.7) s, P<0.001), while the duration of ASP was longer in the ultrasound group ((10.1±1.8) minutes vs. (8.2±1.3) minutes, P<0.001). In terms of complications, the incidence of puncture into the pericardium was lower in the ultrasound group (0 vs.3.4% (4/118), P=0.039); the rate of transient ST-segment elevation post ASP was similar between the ultrasound group and X-ray group (2.4% (3/123) vs. 1.7% (2/118), P=0.999). Conclusion: Intracardiac ultrasound-assisted atrial septal puncture can effectively improve the accuracy of atrial septal puncture, shorten the radiation exposure time, and reduce the complications related to atrial septal puncture.
