Objective:To explore the advantages of internet-based smart healthcare for full-cycle transcatheter edge-to-edge repair (TEER) management in reducing postoperative adverse events rate, improving cardiac function, and enhancing quality of life.Methods:This retrospective study enrolled patients with mitral regurgitation who underwent transcatheter TEER at Beijing Anzhen Hospital Valve Intervention Center between June 2021 and September 2023. Patients were classified into degeneration mitral regurgitation (DMR) and functional mitral regurgitation (FMR) according to etiology, with further stratification by enrollment period into usual care group (June 2021 to October 2022) and full-cycle management group (November 2022 to September 2023). The 1-year postoperative follow-up data were collected and compared between subgroups with the same etiology. Kaplan-Meier survival curves were plotted, and log-rank tests were used to compare the differences in major endpoint event-free survival rates between the two groups. Univariate and multivariate Cox regression and logistic regression analyses were performed to evaluate the impact of the full-cycle management system on patients′ outcomes.Results:A total of 130 patients were included, aged (72.0±8.6) years, including 82 (63%) males. DMR was identified in 84 cases (40 in the usual care group and 44 in the full-cycle management group), while FMR was observed in 46 cases (27 in the usual care group and 19 in the full-cycle management group). Kaplan-Meier analysis demonstrated higher 1-year major endpoint event-free survival rates in the full-cycle management group compared to the usual care group, though the difference was not statistically significant (log-rank P>0.05). Compared to the usual care group, the full-cycle management group showed significantly higher proportions of New York Heart Association classification Ⅰ-Ⅱ patients (DMR: 67% vs. 52%, P=0.031; FMR: 68% vs. 52%, P=0.021), greater 6-minute walking distances (DMR: (346.39±70.41) m vs. (294.11±60.47) m, P=0.012; FMR: (356.60±54.68) m vs. (318.55±39.02) m, P=0.004), and superior Kansas City Cardiomyopathy Questionnaire scores (DMR: 81.50 (74.50, 85.00) points vs. 71.00 (66.00, 82.25) points, P=0.014; FMR: 83.00 (76.00, 85.00) points vs. 74.00 (70.75, 80.00) points, P=0.030). Multivariate logistic regression confirmed the full-cycle management system as an independent predictor for the above improved outcomes (all P<0.05). Conclusion:Smart healthcare-based full-cycle management improves cardiac function and quality of life in mitral regurgitation patients after TEER, demonstrating lower rates of major endpoint events compared to usual care.

Objective:To establish the quality evaluation method of Perillae caulis formula granules based on the three kind of quality indexes of standard decoction. Methods:Eighteen batches of Perillae caulis were collected from different habitats according to different technical requirements, eighteen batches of standard decoction and three batches of formula granules were prepared and the paste-forming rates were calculated. The content of Caffeic acid and Rosmarinic acid were determined and calculated by Ultra High Performance Liquid Chromatography (UPLC). Then the fingerprints of standard decoction of and formula granules of Perillae caulis were established by UPLC . The similarity values of fingerprints between formula granules and standard decoction were calculated. Results:The average paste-forming rate of standard decoction was (7.16±1.97)%. The paste-forming rates of three batches of formula granules were 5.52%, 5.25% and 5.34%, respectively. The average content of Caffeic acid and Rosmarinic acid in standard decoction was (12.06±3.37)mg/g. The contents of three batches of formula granules were 5.52, 5.82, 5.77 mg/g, respectively. Seven common fingerprint peaks were identified in the fingerprints of standard decoction and formula granules, three of which were identified as Caffeic acid, N-Feruloyl Octopus amine and Rosmarinic acid by comparison of reference substance. The fingerprints similarity of Perillae caulis dispensing granules and standard decoction were 1.000, 0.995 and 0.997, respectively. Conclusions:The quality indexes of three batches of formulation granules are consistent with standard decoction. This method can provide basis for the establishment of quality standard of Perillae caulis dispensing granules.

Objective: To investigate the effect of Fuhe decoction on the behavior and levels of monoamine neuro-transmitters in different brain regions in a depression rat model induced by chronic unpredictable mild stimulation (CUMS) combined with social isolation.Methods: Fifty male SD rats were randomly divided into a blank group, model group, fluoxetine group, Chaiqinwendan decoction group, and Fuhe decoction group. Chronic unpredictable mild stimulation combined with a social isolation method was used to replicate the depression rat model. After 42 days of administration, a tail suspension test and high-performance liquid electrochemical detection (HPLC-ECD) were used to detect the behavioral changes and changes in the content of monoamine neurotransmitters norepinephrine (NE), dopamine (DA), 5-hydroxytrytamine (5-HT), and metabolites in different brain regions of rats in each group before and after treatment. Results: Compared with the model group, the epinephrine (E) content in the Fuhe decoction group was highly significantly increased (P < .01). Compared with the model group, the 5-HT content of the pre-frontal cortex in rats in the Fuhe decoction group was highly significantly increased (P < .01). Further-more, compared with the model group, the 5-HT content in the hippocampus of rats in the Fuhe decoction group was significantly increased (P<.05). Conclusion: Fuhe decoction can improve the depression-like behaviors of model rats, and its antide-pressant effect may be related to the increase in 5-HT content in the prefrontal cortex and hippocampus of rats.

Objective:To investigate the concentration of pulmonary surfactant-associated protein D ( SP-D) and interleukin-8 (IL-8) in the bronchoalveolar lavage fluid (BALF) of ACOS patients undergoing mechanical ventilation (MV). Methods:38 patients with ACOS undergoing MV were involved in the study. According to the APACHEⅡscore, the patients were divided into the remission group (n=20) and the aggravation group (n=18). BALF was collected on the 1st and 5th days after MV. The content of IL-8 and SP-D in BALF was measured by ELISA. The levels of IL-8 and SP-D in BALF of the patients with different severity were compared. Results:The level of SP-D was significantly higher on the 5th day than on the 1st day in the remission group,and it decreased more ob-viously in the worsening group (P<0. 05). The level of IL-8 decreased gradually in the remission group but increased gradually in the worsening group. The level of SP-D was negatively correlated with IL-8 level and APACHEⅡ score. Conclusion:The findings suggest that the levels of SP-D and IL-8 in BALF are correlated with prognosis of ACOS patients undergoing MV,and it may prove to be useful as a guidance of therapy and prognosis.

BACKGROUND: Xinjiang is a multi-ethnic region with significant differences in local geographical position, economic development and climatic environment. OBJECTIVE: To analyze the occurrence and development tendency of birth defects, disease categories and disparity among different ethnic groups and regions in Xinjiang.METHODS: A stratified cluster random sampling observation was performed in 13 counties (cities) according to the status of ethnical distribution and local economics of Xinjiang. Quarter Report Sheet on Babies and The defect babies register card were filled as the scheme of Chinese birth defect monitoring, and ICD10 diagnostic code was adopted in birth defect diagnosis. The birth defects rate was calculated from January 2005 to December 2008, and the disease categories and disparity among different ethnic groups and regions in Xinjiang were analyzed. RESULTS AND CONCLUSION: The average incidence rate of birth defect was 9.74‰, which was dramatically descended in 2006 and ascended afterward yearly. The incidence rate of countryside was higher than city, and male more than female. In geography, south of Tianshan Mountain was higher than north and east in birth defect incidence. Among major ethnic groups in Xinjiang, Sibe and Uygur had the highest birth defect incidence rate, followed by Man, Hazakh, and Han. The birth defect incidence of Han, Uygur and Hazakh people showed descend tendency, Hui, Mongolia, and Man people fluctuated, yet Sibe's rate had a change of rise and fall. The first five birth defect entities were neural tube deformity, cleft lips, anencephaly, congenital hydrocephalus and cleft palate combined with cleft lips. The birth defects rates are different from ethnic groups and regions in Xinjiang.

Objective To determine the clinical characteristic, main treatment, and prognosis for the sake of more effective treatments for critically ill patients with H1N1 influenza. Methods Eight critically ill patients with H1N1 influenza in intensive care unit were retrospectively studied, including clinical characteristics, indexex of correlation, and prognosis. Results The acute physiology and chronic health evaluationⅡ score was 19.0±7.8. Five patients died, 4 of whom were caused by respiratory failure. The number of platelets in dead patient was lower than that in healing and improved ones(χ2=8.000,P＜0.05).All the 4 patients treated with glucocorticoid died, 5 out of the 6 patients received invasive mechanical ventilation rather than noninvasive mechanical ventilation, and 3 of them who complicated barotraumas in the lung died at last. Conclusion Critically ill patients with H1N1 influenza have high mortality. Respiratory failure is the main cause of death. Critically ill patients with H1N1 influenza should not be treated with glucocorticoid. Patients who need mechanical ventilation should be treated with invasive mechanical ventilation with low tidal volume and low positive end-expiratory pressure.
