Objective:Analysis of surgical strategies for atrial functional mitral regurgitation with atrial fibrillation.Methods:Retrospective analysis of 112 patients with mitral regurgitation and atrial fibrillation between June 2017 and January 2023. Among them, 56 cases were severe atrial functional mitral regurgitation with atrial fibrillation, and the other 56 cases were degenerative mitral regurgitation with atrial fibrillation. All patients underwent maze Ⅳ procedure and mitral valve surgery. Follow up will be conducted through outpatient follow-up and telephone calls. The condition of postoperative mitral valve is obtained through echo. The postoperative cardiac rhythm is based on the patient's conscious symptoms, electrocardiogram, 24 hour dynamic electrocardiogram.Results:The comparison of preoperative basic data shows that the age, duration of atrial fibrillation, and comorbidity of patients with atrial functional mitral regurgitation are significantly higher than those in the degenerative mitral regurgitation group. All patients successfully completed the surgery. Postoperative death occurred in 2 cases in the atrial mitral regurgitation group. The causes of death were ARDS and pulmonary infection, respectively. The main postoperative complications include bleeding, low cardiac output, pulmonary infection, and acute kidney injury. During follow-up, 43 patients (79.6%) in the atrial mitral regurgitation group maintained sinus rhythm, while 49 patients (87.5%) in the degenerative group. However, there was no statistically significant difference in the Kaplan- Meier curves. In the atrial mitral regurgitation group, there were 47 cases with no mitral regurgitation, 4 cases with mild regurgitation, and 1 case with moderate regurgitation. In the degenerative group, there were 42 cases with no mitral regurgitation, 6 cases with mild regurgitation, 1 case with moderate regurgitation, and 1 case with severe regurgitation. The risk for atrial fibrillation recurrence in the atrial mitral regurgitation is related to postoperative left atrial diameter greater than 50 mm, while in the degenerative group, atrial fibrillation recurrence is related to postoperative left atrial diameter greater than 50 mm and residual mitral regurgitation. Conclusion:Mitral valve repair combined with maze Ⅳ procedure is an effective treatment for patients with severe atrial functional mitral regurgitation and atrial fibrillation. Further improving the success rate of atrial fibrillation and reducing surgical trauma will benefit patients in the future.

Objective:To investigate the current situation of kinesiophobia in patients after heart valve replacement surgery and to analyze its influencing factors, and to provide reference for the intervention research of patients with cardiophobia after cardiac valve replacement.Methods:Using cross-sectional survey method and convenient sampling method, 109 patients who underwent cardiac valve replacement surgery in department of cardiothoracic and vascular surgery of Guangxi Zhuang Autonomous Region People′s Hospital from March 2021 to January 2022 were selected as the study subjects. The patients were surveyed with the general questionnaire, Tampa Scale of Kinesiophobia and Visual Analogue Scale.Results:After heart valve replacement, the score of Tampa Scale of Kinesiophobia was (46.90 ± 9.30) points. The score of Visual Analogue Scale was (5.83 ± 1.01) points. The score of Tampa Scale of Kinesiophobia was positively correlated with the score of Visual Analogue Scale ( r=0.46, P<0.01). Multiple linear regression analysis showed that patient′s age, cardiac function level, left ventricular ejection fraction, pain were the main influencing factors of Kinesiophobia ( t values were -2.37-4.34, all P<0.05). Conclusions:Medical staff should understand and accurately assess the status of patient′s kinesiophobia after heart valve replacement surgery, identify high-risk groups of kinesiophobia, and take targeted nursing measures to effectively alleviate postoperative pain, thereby reducing the incidence of kinesiophobia in patients, helping patients to carry out early functional exercise, and prorroting physical recovery.

Objective:To investigate Helicobactor pylori (H. pylori) infection status and interfamilial transmission pattern in Zhengzhou area. Methods:A cross-sectional study was conducted from September 2020 to march 2021, among 731 individual from 266 families randomly selected from 9 communities of Zhengzhou area. H. pylori infection status was determined by serum antibody tests, and 13C-urea breath test was performed in the previously eradicated population to clarify the current infection status. The individual and familial infection rate, infection status for couples and children and adolescent were analyzed. Results:Among 731 individuals from 266 families, 397 of them were H. pylori positive. The individual infection rate was 54.31% (397/731); among infected individuals 77.83% (307/397) were infected with type Ⅰ strain, 22.67% (90/397) were infected by type Ⅱ strain. Annual household income ( χ2=0.419, 0.410, 0.213, all P>0.05), smoking history (χ 2=0.071, P>0.05), drinking history ( χ2=0.071, P>0.05), dining place ( χ2=0.009, P>0.05), gastrointestinal symptoms ( χ2=0.047, P>0.05), family history of gastric disease ( χ2=0.069, P>0.05), and history of gastric cancer ( χ2=0.004, P>0.05) had no significant differences between H. pylori-positive and -negative groups, but the infection rate in individuals with higher education level was lower ( χ2=4.449, P<0.05). The infection rate was significantly higher in≥18 age groups compared with<18 age groups ( χ2=6.531, 23.362, 20.671, 24.244, 37.948, 14.597 and 5.170, all P<0.05). The familial H. pylori infection rate was 87.59% (233/266), and in 61 families all member were infected (26.18%, 61/233). The positive rate was 23.08% (6/26) in 50 families with children under 18 years when both parents were infected. Among 231 coupled families, both couples were infected in 78 families (33.76%), one couple was infected in 113 families (48.92%), and both couples were not infected in 40 (17.32%). With the increase of marriage time, the infection rate of both spouses increased significantly ( χ2=7.775, 12.662, 15.487, all P<0.05). Conclusions:The distribution of H. pylori infection presents a family cluster pattern, and intrafamilial infection is an important transmission rout of H. pylori. The type I strain of H. pylori is the dominate strain in this area.

Objective:To explore the clinical effect of repairing interphalangeal joint defect of hand with free transfer of part of the 2nd metatarsophalangeal joint tissue flap precisely cut with the aid of digital 3D printing technology.Methods:From December 2016 to December 2020, 7 patients with partial joint defects of proximal interphalangeal joints of fingers were treated in Department of Hand and Foot Surgery, Shunde Hospital Affiliated to Guangzhou Medical University(Foshan Shunde Lecong Hospital). Before surgery, three-dimensional data of hand and foot bones were collected, and the 3D printing model was used to simulate the operation in vitro. During the operation, the first dorsal metatarsal artery-the 2nd dorsal metatarsal artery was used as the pedicle, and the 2nd metatarsophalangeal joint composite tissue flap with a required size was harvested with the assistance of the navigation template to tranfer and repair the small joint defects of hand. All 7 cases entered follow-up at outpatient and telephone. Results:All 7 cases survived. Postoperative follow-up was 3-24(mean 9.5) months, Range of motion of the repaired interphalangeal joint was (56 ± 6)°; According to the Evaluation Standard of Thumb and Finger Reconstruction Function of the Society of Hand Surgery of the Chinese Medical Association, 2 cases were excellent, 4 cases were good, and 1 case was poor.Conclusion:Transfer of the free 2nd metatarsophalangeal joint tissue flap assisted by 3D printing technology in repair of the small joint defect of the hand can accurately harvest the tissue flap, which is clinically reliable.

Objective:To study the influence of Mei mini maze procedure for atrial functional mitral regurgitation.Methods:The data of 33 patients with atrial fibrillation and atrial functional mitral regurgitation from January 2017 to June 2020 were retrospectively analyzed. All patients received Mei mini maze procedure for atrial fibrillation. The procedure is carried out thoracoscopically through the left thoracic approach. The ablation of atrial fibrillation includes bilateral circumferential pulmonary vein ablation, isolation of the left atrium posterior wall, left atrial appendage resection, ablation of Marshall's ligament and autonomic ganglion, etc. Follow-up was conducted by outpatient follow-up and telephone. Postoperative heart rhythm was recorded by the patient's symptoms, electrocardiogram, 24 h holter and other examinations. Postoperative mitral valve lesions were obtained by echocardiography.Results:33 patients successfully completed the operation. There was no conversion to thoracotomy and no perioperative death. Thirty patients(90.9%) maintained sinus rhythm at discharge. Before discharge, 16 patients had no mitral regurgitation in echocardiography, 8 patients had mild mitral regurgitation, and 9 patients had moderate mitral regurgitation. Follow-up was 1-4 years after discharge, with a mean of(2.6±1.1) years. Sinus rhythm was maintained in 23 patients(69.7%). 17 patients had no mitral regurgitation, 9 had mild mitral regurgitation, 6 had moderate, and 1 had severe mitral regurgitation. The degree of regurgitation in 25 patients was reduced compared with pre-operation, 5 patients remained unchanged, and 3 patients mitral regurgitation aggravated. Unreduced atrial functional mitral regurgitation was associated with recurrence of atrial fibrillation by Cox multivariate analysis.Conclusion:This study found a close relationship between atrial fibrillation rhythm and atrial functional mitral regurgitation. Most moderate atrial functional mitral regurgitation can be alleviated by effective treatment for atrial fibrillation. It is not recommended that patients with severe atrial functional mitral regurgitation only receive treatment for atrial fibrillation.

Background: and Purpose To examine the clinical and safety outcomes after endovascular treatment (EVT) for acute basilar artery occlusion (BAO) with different anesthetic modalities. Methods: This was a retrospective analysis using data from the Endovascular Treatment for Acute Basilar Artery Occlusion (ATTENTION) registry. Patients were divided into two groups defined by anesthetic modality performed during EVT: general anesthesia (GA) or non-general anesthesia (non-GA). The association between anesthetic management and clinical outcomes was evaluated in a propensity score matched (PSM) cohort and an inverse probability of treatment weighting (IPTW) cohort to adjust for imbalances between the two groups. Results: Our analytic sample included 1,672 patients from 48 centers. The anesthetic modality was GA in 769 (46.0%) and non-GA in 903 (54.0%) patients. In our primary analysis with the PSM-based cohort, non-GA was comparable to GA concerning the primary outcome (adjusted common odds ratio [acOR], 1.01; 95% confidence interval [CI], 0.82 to 1.25; P=0.91). Mortality at 90 days was 38.4% in the GA group and 35.8% in the non-GA group (adjusted risk ratio, 0.95; 95% CI, 0.83 to 1.08; P=0.44). In our secondary analysis with the IPTW-based cohort, the anesthetic modality was significantly associated with the distribution of modified Rankin Scale at 90 days (acOR: 1.45 [95% CI: 1.20 to 1.75]). Conclusion In this nationally-representative observational study, acute ischemic stroke patients due to BAO undergoing EVT without GA had similar clinical and safety outcomes compared with patients treated with GA. These findings provide the basis for large-scale randomized controlled trials to test whether anesthetic management provides meaningful clinical effects for patients undergoing EVT.

Objective:To explore the clinical effect of a modified single-trunk arterialised venous flap in reconstruction of soft tissue defect in hand and foot.Methods:From January 2019 to June 2022, 25 patients with soft tissue defect in hand and foot were treated in the Department of Hand and Foot Plastic Surgery of Lecong Hospital of Shunde in Foshan. The soft tissue defects were reconstructed with a venous flap, of which a single trunk of vein was ligated and then a blood flux of the flap was re-established via a modified single vein trunk. One patient had soft tissue defect in dorsal foot and toes, 3 patients had defects in dorsal hand, 3 patients had defects in 2 digits and 18 patients had defects in single-digit. The sizes of defects were 2.0 cm×1.0 cm-10.0 cm×4.5 cm. The sizes of flaps were 2.0 cm×1.0 cm-12.0 cm×5.5 cm. Donor sites of the 19 cases were directly sutured and 6 were covered by skin grafts. The postoperative follow-ups were conducted at outpatient clinics and via telephone reviews to observe the survival of flaps. Functional recovery of 23 cases whose soft tissue defects in hand were evaluated according to the Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association. The sensory recovery of flaps was evaluated according to the comprehensive flap scale.Results:All 25 single-trunk venous flaps survived successfully. There were small number of blisters on 5 flaps, due to tissue oedema. One patient lost in follow-up. The other 24 patients had 2-18 months of follow-up. The appearance of flaps was soft and thin, with wear-resistant. According to the Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, the function recovery were excellent in 12 cases, good in 9 cases and poor in 2 cases. Sensations of the flaps were 90-99 point with an average of 97 point according to the comprehensive flap scale, of which 22 flaps were in excellent and 2 in good.Conclusion:The method of ligation of single vein-trunk to make a arterialised venous flap is a simple surgical procedure. There are many selections of donor site with minimum damage. It is an effective method and with satisfactory outcomes.
