Objective:To analyze the registration status of clinical trials of TCM treatment for functional dyspepsia (FD); To provide references for relevant clinical trial registration and implementation.Methods:The clinical registration trials of TCM for the treatment of FD were retrieved from ChiCTR and clinicaltrials.gov until January 1st, 2025. Excel 2019 was used to extract and analyze study characteristics, including basic information (registration time, country/region, institution, funding source), study features and quality (study type, trial design, phase, number of centers, sample size, interventions, outcome measures, methodological quality, reporting quality), as well as recruitment status and ethical review.Results:A total of 89 registered studies were included. Registration began in 2008 with 3 studies, peaking in 2021 with 14 studies. The studies involved 6 countries, with domestic trials covering 18 provincial-level regions in China and 52 clinical trial institutions. Primary funding sources were national funding and pharmaceutical company support. Most studies were interventional with randomized parallel-controlled designs, commonly using simple randomization. Post-marketing drug trials were the most frequent phase, and single-center trials predominated, involving a total sample size of 19 776 cases. Common interventions included acupuncture/massage and Chinese patent medicines. Frequently used outcome measures were effectiveness rate, symptom evaluation, and quality of life assessment, though issues existed with non-standardized reporting and lack of TCM-specific indicators. Methodological quality needed further improvement.Conclusions:Although the number of registered clinical trials of TCM treatment for FD has increased, the overall quantity remains insufficient. Researchers should emphasize optimization of registration details and study protocols to further enhance registration quality.

Objective     To analyze the perioperative outcomes of uniportal thoracoscopic lobectomy compared with three-port thoracoscopic lobectomy. Methods     Data were extracted from the Western China Lung Cancer Database, a prospectively maintained database at the Department of Thoracic Surgery, West China Hospital, Sichuan University. Perioperative outcomes of the patients who underwent uniportal or three-port thoracoscopic lobectomy for lung cancer during January 2014 through April 2021 were analyzed by using propensity score matching. Altogether 5 817 lung cancer patients were enrolled who underwent thoracoscopic lobectomy (uniportal: 530 patients; three-port: 5 287 patients). After matching, 529 patients of uniportal and 1 583 patients of three-port were included. There were 529 patients with 320 males and 209 females at median age of 58 (51, 65) years in the uniportal group and 1 583 patients with 915 males and 668 females at median age of 58 (51, 65) years in the three-port group. Results     Uniportal thoracoscopic lobectomy was associated with less intraoperative blood loss (20 mL vs. 30 mL, P<0.001), longer operative time (115 min vs. 105 min, P<0.001) than three-port thoracoscopic lobectomy. No significant difference was found between the two groups regarding the number of lymph node dissected, rate of conversion to thoracotomy, incidence of postoperative complication, postoperative pain score within 3 postoperative days, length of hospital stay, or hospitalization expenses. Conclusion     Uniportal video-assisted thoracoscopic lobectomy is safe and effective, and the overall perioperative outcomes are comparable between uniportal and three-port strategies, although the two groups show differences in intraoperative blood loss.

Objective     To identify the risk factors for postoperative recurrence of peripheral solid small-nodule lung cancer (PSSNLC) (T≤2 cm), and to explore the effects of surgery types on prognosis. Methods     We extracted data from Western China Lung Cancer Database (WCLCD), a prospectively maintained database at the Department of Thoracic Surgery, West China Hospital, Sichuan University, and Surveillance, Epidemiology, and End Results (SEER)  database for peripheral solid small-nodule lung cancer patients (T≤2 cm N0M0, stageⅠ) who underwent surgery between 2005 and 2016. We used univariable and multivariable logistic regression to analyze risk factors for recurrence of PSSNLC. We applied propensity-score matching to compare the long-term results of segmentectomy and lobectomy, as well as the survival of patients from WCLCD and SEER. We finally included 4 800 patients with PSSNLC (T≤2 cm N0M0)(WCLCD: SEER=354∶4 446). We matched 103 segmentectomies and 350 lobectomies in T≤1 cm, and 280 segmentectomies and 1 067 lobectomies in 1 cm

Objective    To explore the safety and effectiveness of video-assisted thoracoscopic surgery (VATS) pneumonectomy for bronchiectasis. Methods    The clinical data of 164 patients undergoing VATS pneumonectomy or open thoracotomy for bronchiectasis in our hospital from March 2002 to July 2012 were retrospectively analyzed. Patients were divided into two groups according to different surgical methods: a thoracotomy group (122 patients, 63 males, 59 females) and a thoracoscopic surgery group (42 patients, 15 males, 27 females). Surgical and follow-up indicators were compared between the two groups. Results    There was no difference between the two groups in the blood loss, operation time, perioperative mortality or complication. However patients undergoing VATS had shorter length of postoperative stay than those undergoing thoracotomy (6.9±2.6 d vs. 8.1±3.1 d, P=0.030). In the thoracoscopic surgery group, 3 patients were lost to follow-up and in the thoracotomy group, 5 patients were lost to follow-up. In a median follow-up of 51 months (ranging from 2 to 116 months), 36 patients (92.3%) fully recovered with no sputum or haemoptysis and 3 (7.7%) partially recovered with a reduced sputum or haemoptysis in the thoracoscopic surgery group; 105 (89.7%) fully recovered with no sputum or haemoptysis, 10 (8.5%) partially recovered with a reduced sputum or haemoptysis while 2 (1.7%) without any improvement in the thoracotomy group with no statistical difference (P=0.700). Conclusion    VATS pneumonectomy for bronchiectasis is equivalent to thoracotomy in terms of safety and effectiveness, and can be used as an alternative surgical procedure for the treatment of bronchiectasis.

Objective The fractional realization of delayed parameters will occurs when using microphone array technology in cochlear implants. To study the design and mismatch feature of fractional delay filter so as to meet the requirement of fractional delay realization in cochlear implants. Methods According to the characteristics of small cochlear implants and delay requirements, a fractional delay filter was designed by least mean square method. Results The fractional delay filtering method based on least mean square interpolation can achieve fractional delay, and can minimize the average error and the mean square error of the whole frequency band. Conclusions The fractional delay filter based on least mean square interpolation has the features of mismatch and high-order flat error, which makes it have theoretical and engineering value and providing a parameter selection method for the design of fractional delay filter.

Background and objective It is unknown that the postoperation fast-track recovery and in hospital cost of the lobectomy in lung cancer, we explored the inlfuencing factor of postoperative fast-track recovery and in hospital cost atfer undergoing lobectomy for lung cancer. Methods We retrospectively reviewed the medical records of all patients (n=176) who underwent lobectomy for lung cancer between January 2010 and November 2011 by a thoracic surgeon. Results hTe hospital costs of video-assisted thoracic surgery (VATS) lobectomy (47,308.21 ￥) is signiifcantly higher than open lobectomy (45,664.31 ￥)(P=0.007). hTe hospital costs of body mass index (BMI)≥24 kg/m2 (51,186.99 ￥) is signiifcantly higher than BMI<24 kg/m2 (41,701.64 ￥)(P=0.032). hTe hospital stay of VATS lobectomy (5.70 d) is signiifcantly less than open lobectomy (7.10 d)(P<0.001). Conclusion hTese ifndings indicate that preoperative pulmonary rehabilitation and VATS lobectomy is contrib-uted to fast-track recovery for patients who undergo lobectomy, but increase the hospital costs.
