Objective:To systematically evaluate the effect of cognitive behavioral therapy (CBT) in elderly patients with depression.Methods:The randomized controlled trials on the effect of CBT in elderly patients with depression, published until December 15, 2022, were searched in PubMed, CINHAL, Cochrane Library, China Biology Medicine, China National Knowledge Infrastructure, WanFang Data, and VIP. Two researchers independently screened the literature, extracted data, and used the revised Cochrane risk of bias tool for randomized trials (ROB 2.0) to evaluate the quality of the included studies. Statistical analysis was conducted using Stata 16.0, and the quality of evidence was rated using Appraisal of Guidelines for Research and Evaluation (GRADE) predictor software.Results:A total of 11 randomized controlled trials were included, with a total of 833 elderly patients with depression. Randomized effect models were used to analyze outcome indicators such as depression, anxiety, and quality of life by combining effect quantities. Meta-analysis and GRADE evidence quality showed that compared to the control group, medium quality evidence showed that CBT could relieve depression in elderly depression patients with a statistical difference [ SMD=-1.58, 95% CI (-2.16, -0.99), P<0.05]. Low quality evidence suggested that CBT could alleviate anxiety in elderly depression patients also with a statistical difference [ SMD=-2.25, 95% CI (-4.04, -0.47), P<0.05]. Very low quality evidence indicated that CBT did not significantly improve the quality of life in elderly depression patients compared to conventional or pharmacological treatment [ SMD=-0.09, 95% CI (-2.07, 1.88), P>0.05] . Conclusions:Existing evidence suggests that CBT can alleviate depression and anxiety in elderly depression patients, but its improvement in quality of life is not yet significant. Treatment feedback and forms of CBT may become a research focus in recent years on intervention for elderly depression patients.

In order to cultivate qualified oral clinicians, strengthen examination management, and strictly implement process assessment, Special Training Base of Oral and Maxillofacial Radiology in West China Hospital of Stomatology, Sichuan University, has implemented a whole-process and diversified assessment reform. In the part of process assessment, firstly the students were asked to fill in the workload form to give timely feedback on training and truly reflect attendance records; secondly, the performance of trainees in class was comprehensively evaluated in clinical training and theoretical teaching to improve their ability of comprehensive thinking of clinical problems. In the part of result assessment, the traditional theoretical assessment method was weakened, and the ability of comprehensive clinical research was strengthened. Trainees were guided to choose the topic flexibly and use standardized PPT format, and a comprehensive score was determined after assessment. Experts were invited to give their advice, so as to enhance the clinical confidence and scientific research confidence of trainees and help them expand their learning depth and breadth within the limited training time. The analysis of examination methods and assessment results shows that the "whole-process and diversified" assessment mode can truly reflect the training results of trainees and lay a solid foundation for further improvement and implementation of standardized training.

Objectives: To investigated the safety and efficacy of treating patients with acute non-ST-segment elevation myocardial infarction (NSTEMI) and elevated levels of N-terminal pro-hormone B-type natriuretic peptide (NT-proBNP) with levosimendan within 24 hours of first medical contact (FMC). Methods: This multicenter, open-label, block-randomized controlled trial (NCT03189901) investigated the safety and efficacy of levosimendan as an early management strategy of acute heart failure (EMS-AHF) for patients with NSTEMI and high NT-proBNP levels. This study included 255 patients with NSTEMI and elevated NT-proBNP levels, including 142 males and 113 females with a median age of 65 (58-70) years, and were admitted in the emergency or outpatient departments at 14 medical centers in China between October 2017 and October 2021. The patients were randomly divided into a levosimendan group (n=129) and a control group (n=126). The primary outcome measure was NT-proBNP levels on day 3 of treatment and changes in the NT-proBNP levels from baseline on day 5 after randomization. The secondary outcome measures included the proportion of patients with more than 30% reduction in NT-proBNP levels from baseline, major adverse cardiovascular events (MACE) during hospitalization and at 6 months after hospitalization, safety during the treatment, and health economics indices. The measurement data parameters between groups were compared using the t-test or the non-parametric test. The count data parameters were compared between groups using the χ² test. Results: On day 3, the NT-proBNP levels in the levosimendan group were lower than the control group but were statistically insignificant [866 (455, 1 960) vs. 1 118 (459, 2 417) ng/L, Z=-1.25,P=0.21]. However, on day 5, changes in the NT-proBNP levels from baseline in the levosimendan group were significantly higher than the control group [67.6% (33.8%,82.5%)vs.54.8% (7.3%,77.9%), Z=-2.14, P=0.03]. There were no significant differences in the proportion of patients with more than 30% reduction in the NT-proBNP levels on day 5 between the levosimendan and the control groups [77.5% (100/129) vs. 69.0% (87/126), χ²=2.34, P=0.13]. Furthermore, incidences of MACE did not show any significant differences between the two groups during hospitalization [4.7% (6/129) vs. 7.1% (9/126), χ²=0.72, P=0.40] and at 6 months [14.7% (19/129) vs. 12.7% (16/126), χ²=0.22, P=0.64]. Four cardiac deaths were reported in the control group during hospitalization [0 (0/129) vs. 3.2% (4/126), P=0.06]. However, 6-month survival rates were comparable between the two groups (log-rank test, P=0.18). Moreover, adverse events or serious adverse events such as shock, ventricular fibrillation, and ventricular tachycardia were not reported in both the groups during levosimendan treatment (days 0-1). The total cost of hospitalization [34 591.00(15 527.46,59 324.80) vs. 37 144.65(16 066.90,63 919.00)yuan, Z=-0.26, P=0.80] and the total length of hospitalization [9 (8, 12) vs. 10 (7, 13) days, Z=0.72, P=0.72] were lower for patients in the levosimendan group compared to those in the control group, but did not show statistically significant differences. Conclusions: Early administration of levosimendan reduced NT-proBNP levels in NSTEMI patients with elevated NT-proBNP and did not increase the total cost and length of hospitalization, but did not significantly improve MACE during hospitalization or at 6 months.

Objective: To analyze the epidemic characteristics and drug resistance of pulmonary tuberculosis among the floating population in Beijing and to provide a scientific basis for formulating strategies for the prevention and control of tuberculosis among the floating population. Methods: Data of tuberculosis patients who were positive for Mycobacterium tuberculosis culture was collected from 16 districts and one municipal institution of tuberculosis control and prevention in Beijing in 2019. The strain samples were tested for drug sensitivity by the proportional method. According to household registration location, patients were divided into the floating population and Beijing registration. SPSS 19.0 software analyzed tuberculosis patients' epidemic characteristics and drug resistance in the floating population. Results: In 2019, there were 1 171 culture-positive tuberculosis patients in Beijing, among the floating population, 593 (50.64%) patients were identified, with a male-to-female sex ratio of 2.2∶1 (409∶184). Compared to patients under household registration as Beijing residents, a higher proportion of young adults aged 20-39 years (65.09%,386/593) were noticed, with 55.65% (330/593) reported from the urban areas and 96.80% (574/593) were reported the first time. The differences were statistically significant (all P<0.05). After completing the drug sensitivity test, 37 cases were with multiple drug-resistant tuberculosis, accounting for 6.24% (37/593). The rates of isoniazid resistance (42.11%,8/19) and multidrug resistance (21.05%,4/19) in floating population patients after retreatment were significantly higher than those in newly treated patients (11.67%, 67/574 and 5.75%, 33/574), and the differences were statistically significant (all P<0.05). Conclusions: Most patients with tuberculosis in the floating population in Beijing in 2019 were young males aged 20-39 years. The reporting areas were urban areas and the newly treated patients mainly. The patients with tuberculosis in the re-treated floating population were more likely to suffer from multidrug and drug resistance, which should be taken as the key population for prevention and control.

Objective: To propose total posterior nasal neurectomy with transection of sphenopalatine neurovascular bundle from anatomy for the treatment of allergic rhinitis, and to explore its clinical application. Methods: Two fresh cadaveric heads (4 sides) were dissected through endoscopic transnasal middle meatus approach at Otorhinolaryngology Anatomy Laboratory of China-Japan Friendship Hospital. The structures of the craniofacial bone related to the surgical approach were observed. Twelve patients with allergic rhinitis who treated in Department of Otorhinolaryngology, China-Japan Friendship Hospital from Feb. 1 2019 to Jun. 10 2021 were selected. All the patients were treated by posterior nasal neurotomy with the technique of complete transection of sphenopalatine neurovascular bundle and followed up for 1 year after sugery. During the follow-up, 2 patients were lost. The other 10 patients included 4 males and 6 females, aging from 29 to 69 years. Visual Analogue Scale (VAS) and Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) were used to evaluate the effect of the surgery. SPSS 25.0 software was used for statistical analysis. Results: Important anatomic landmarks of transnasal middle meatus approach were obtained during anatomy, such as ethmoid crest, sphenopalatine foramen/notch, palatine orbital process and sphenopalatine process. The postoperative VAS scores of nose, eye, pharynx, ear and whole body and total VAS scores were significantly lower than those before operation, with statistically significant difference (nose 2.50±1.70 vs 6.47±2.17, eyes 1.15±0.89 vs 3.60±2.57, pharynx 1.30±1.36 vs 4.25±3.64, ear 1.10±1.03 vs 2.67±2.00, whole body 1.08±1.24 vs 3.60±1.17, total 7.13±4.31 vs 20.58±9.05, all P<0.05). The postoperative RQLQ scores of sleep, nose, eyes, practical problems, emotion, activity and the total RQLQ scores of patients were significantly lower than those before operation, with statistically significant difference (sleep 0.80±0.69 vs 2.93±1.33, nose 1.38±1.18 vs 3.93±1.50, eyes 0.58±0.66 vs 1.80±1.25, practical problems 1.10±1.22 vs 3.03±1.84, emotion 1.00±1.81 vs 2.58±2.00, activity 2.77±2.93 vs 6.00±1.85, total 8.99±8.92 vs 22.42±8.69, all P<0.05). There was no significant difference in preoperative and postoperative scores of non-nasal/ocular symptoms (1.37±1.60 vs 2.16±1.12, P=0.166). There was no other complication except 2 cases with short-term postoperative numbness. Conclusions: Total posterior nasal neurectomy with transection of sphenopalatine neurovascular bundle is a safe, effective and feasible method for the treatment of intractable allergic rhinitis, and its long-term efficacy needs further observation.

Interstitial fluid (ISF) flow through vascular adventitia has been discovered recently. However, its kinetic pattern was unclear. We used histological and topographical identification to observe ISF flow along venous vessels in rabbits. By magnetic resonance imaging (MRI) in live subjects, the inherent pathways of ISF flow from the ankle dermis through the legs, abdomen, and thorax were enhanced by paramagnetic contrast. By fluorescence stereomicroscopy and layer-by-layer dissection after the rabbits were sacrificed, the perivascular and adventitial connective tissues (PACTs) along the saphenous veins and inferior vena cava were found to be stained by sodium fluorescein from the ankle dermis, which coincided with the findings by MRI. The direction of ISF transport in a venous PACT pathway was the same as that of venous blood flow. By confocal microscopy and histological analysis, the stained PACT pathways were verified to be the fibrous connective tissues, consisting of longitudinally assembled fibers. Real-time observations by fluorescence stereomicroscopy revealed at least two types of spaces for ISF flow: one along adventitial fibers and another one between the vascular adventitia and its covering fascia. Using nanoparticles and surfactants, a PACT pathway was found to be accessible by a nanoparticle of <100 nm and contained two parts: a transport channel and an absorptive part. The calculated velocity of continuous ISF flow along fibers of the PACT pathway was 3.6‒15.6 mm/s. These data revealed that a PACT pathway was a "slit-shaped" porous biomaterial, comprising a longitudinal transport channel and an absorptive part for imbibition. The use of surfactants suggested that interfacial tension might play an essential role in layers of continuous ISF flow along vascular vessels. A hypothetical "gel pump" is proposed based on interfacial tension and interactions to regulate ISF flow. These experimental findings may inspire future studies to explore the physiological and pathophysiological functions of vascular ISF or interfacial fluid flow among interstitial connective tissues throughout the body.

Reasonable intra-hospital hierarchical diagnosis and treatment system will effectively guide the patients to see a doctor on demand and improve the efficiency of medical services. Beijing Tongren Hospital, Capital Medical University, has explored the intra-hospital hierarchical diagnosis and treatment system depending on different situatioins such as for new patients, subsequent visit patient, and the same patients with different clinical stage. Through establishing a series of intra-hospital hierarchical diagnosis and treatment modes, such as the well-known expert team, the outpatient service for specialized diseases, the multidisciplinary outpatient service for complex diseases, the nursing service, and the pharmaceutical care service, the outpatients could be oriented by specialties and disciplines and graded by the complexity in diagnosis and treatment of diseases. Relying on the appointment methods such as referral and revisit to open up the information channel, it can optimize the time cost and economic cost of patients, reflect the functional positioning of the tertiary hospitals, and improve patients′ sense of medical access and happiness.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can cause acute respiratory distress syndrome, hypercoagulability, hypertension, and multiorgan dysfunction. Effective antivirals with safe clinical profile are urgently needed to improve the overall prognosis. In an analysis of a randomly collected cohort of 124 patients with COVID-19, we found that hypercoagulability as indicated by elevated concentrations of D-dimers was associated with disease severity. By virtual screening of a U.S. FDA approved drug library, we identified an anticoagulation agent dipyridamole (DIP) , which suppressed SARS-CoV-2 replication . In a proof-of-concept trial involving 31 patients with COVID-19, DIP supplementation was associated with significantly decreased concentrations of D-dimers ( < 0.05), increased lymphocyte and platelet recovery in the circulation, and markedly improved clinical outcomes in comparison to the control patients. In particular, all 8 of the DIP-treated severely ill patients showed remarkable improvement: 7 patients (87.5%) achieved clinical cure and were discharged from the hospitals while the remaining 1 patient (12.5%) was in clinical remission.
