The aim of this study is to investigate the protective effect of idebenone (IDE) combined with borneol (BO) against Parkinson's disease (PD). In this study, wild-type AB zebrafish and transgenic Tg ( vmat2: GFP) zebrafish with green fluorescence labeled dopamine neurons were used to establish the PD model with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine hydrochloride (MPTP). Following drug treatment, the behavioral performance and dopamine neuron morphology of zebrafish were evaluated, and regulation of dopamine signaling pathway-related genes was determined using RT-qPCR. The results showed that IDE combined with BO improved the behavioral disorders of zebrafish such as bradykinesia and shortening movement distance, also effectively reversed the damage of MPTP-induced dopaminergic neurons. At the same time, the expression of dopamine synthesis and transportation-related genes was up-regulated, and the normal function of the signal transduction pathway was restored. The combination showed a better therapeutic effect compared to the IDE monotherapy group. This study reveals the protective mechanism of IDE combined with BO on the central nervous system for the first time, which provides an important experimental basis and theoretical reference for clinical combination strategy in PD treatment.

Objective To analyze the clinical manifestations and epidemiological characteristics of influenza in Hubei. Methods Pharyngeal swab specimens from 16,500 patients with suspected influenza infection admitted to our hospital from January 2020 to December 2022 were selected. Viral detection and serotyping were performed by fluorescence quantitative polymerase chain reaction. Furthermore, the epidemiological and clinical data of patients were collected to analyze the clinical features and epidemiological characteristics of influenza viruses. Results A total of 16 500 clinical specimens were tested in this study, with a positive detection rate of 16.27% (2 684/16 500). The positive detection rate was 5.10% (862/16 500) for influenza A virus, 10.13% (1 672/16 500) for influenza B virus and 0.91% (150/16 500) for mixed influenza. The positive detection rate of influenza viruses was on the rise from 2020 to 2022 , reaching 18.43% in 2022. Seasonal distribution analysis denoted that the highest positive detection rates were observed in spring (18.23%) and winter (19.72%), with statistical difference (P<0.05). In terms of age distribution, patients<12 years (19.14%) had the highest positive detection rate, followed by those >60 years (17.71%), with statistical difference (P<0.05). From 2020 to 2022, the positive detection rate of influenza virus was 16.89% in males, which was higher than 15.63% in females (P<0.05). The main clinical symptoms were fever (86.89%) and cough (80.27%) for influenza A virus infections, cough (92.52%) and fever (86.06%) for influenza B virus infections, and cough (94.00%), fever (88.00%) and runny nose (86.00%) for mixed infections. Conclusion The influenza B viruses are the leading cause of influenza in Hubei from 2020 to 2022, and the infection demonstrates an increasing annual trend, with a high prevalence in winter and spring. Furthermore, children and the elderly are high-risk populations, and clinical manifestions are mainly cough and fever.

Objective To investigate the relationship between gene mutation characteristics and immunological markers in patients with small cell lung cancer.Methods From January 2019 to 2020,155 patients with small cell lung cancer were admitted.Gene mutations were detected in these patients using target gene capture and sequencing method.Moreover,the tumor mutational burden(TMB)and expression of PD-L1 in some patients were detected.Results A total of 326 gene mutations were detected in the patients,the most significant of which were TP53 and RB1.Among the 8 genes with mutation frequency higher than 15％,patients with KMT2D,KMT2C,FAT1 and NOTCH1 mutations had higher TMB than those without mutation,and the difference was statistically significant(P＜0.05).Conclusion The most common mutated genes in patients with small cell lung cancer are TP53 and RB1.KMT2D,KMT2C,FAT1 and NOTCH1 may be potential markers for the efficacy of immunotherapy in small cell lung cancer.

Objective:To compare the efficacy of pneumovesicoscopic Cohen and Politano-Leadbetter procedures in the treatment of vesicoureteral junction obstruction (VUJO) in children.Methods:The data of 48 children with VUJO who underwent operations in the Department of Urology, Anhui Provincial Children′s Hospital from January 2017 to December 2021 were retrospectively analyzed.According to the operation time, the patients were divided into the pneumovesicoscopic Cohen group(group C) (28 cases) and pneumovesicoscopic Politano-Leadbetter group(group P) (20 cases). The operation time, postoperative urinary catheterization duration, hematuria duration, hospitalization time, and the improvement of hydronephrosis, ureteral dilatation, and renal function after surgery were compared between the 2 groups.The enumeration data were compared by the χ2 test or Fisher′ s exact probability method.The measurement data were compared by the t-test. Results:All the 48 children were successfully operated on by the same surgeon, without conversion to open surgery.Six cases in the group C had a megaureter and underwent ureter tailoring.Two cases in the group P had calyceal and ureteral calculi, which were all removed after operation.There was a statistically significant difference in the operation time between group C and group P[(136.5±35.4) min vs.(165.8±33.2) min, t=-3.154, P=0.002]. The patients were followed up for (10.3±2.6) months after operation.There were 8 cases and 6 cases of urinary tract infection in group C and group P within 2 months after the operation, respectively.They all improved after conservative anti-infection treatment, and the infection was well controlled after removal of the D-J tube.Besides, their intravenous pyelography 6 months after operation showed that the ureter was unobstructed.In group C, 6 months after the operation, the anterior and posterior diameters of the renal pelvis [(1.62±0.54) cm vs.(2.55±1.24) cm, t=-5.027, P=0.001] and the largest diameter of the ureter [(0.95±0.27) cm vs.(1.51±0.52) cm, t=-8.495, P<0.001] were significantly decreased, compared with those before operation.However, the renal cortex thickness was increased significantly [(1.47±0.25) cm vs.(0.86±0.46) cm, t=2.028, P=0.004], and the renal function (as indicated by the diuretic nephrogram) was notably improved [(46.27±2.16)% vs.(41.83±3.04)%, t=1.647, P=0.030]. In group P, 6 months after operation, the anterior and posterior diameters of the renal pelvis[(1.48±0.82) cm vs.(2.68±1.41) cm, t=-2.740, P=0.003] and the maximum diameter of the ureter [(1.05±0.46) cm vs.(1.36±0.27) cm, t=-1.635, P=0.040] were significantly smaller than those before operation.However, the renal cortical thickness was increased [(1.38±0.33) cm vs.(0.74±0.39) cm, t=9.073, P<0.001], and the renal function (as indicated by the diuretic nephrogram) was significantly improved [(45.18±3.35)% vs.(39.55±2.49)%, t=1.277, P=0.030]. Politano-Leadbetter surgery outperformed Cohen surgery in promoting the recovery of the anterior and posterior diameters of the renal pelvis [(1.48±0.82) cm vs.(1.62±0.54) cm, t=-1.748, P=0.030]. Conclusions:Pneumovesicoscopic Politano-Leadbetter operation can establish a longer submucosal tunnel without changing the ureteral shape and opening position, having good effects in treating VUJO combined with calyceal and ureteral calculi.Pneumovesicoscopic Politano-Leadbetter operation can also better improve postoperative recovery from hydronephrosis than Cohen operation.However, the pneumovesicoscopic Politano-Leadbetter operation is more difficult and requires longer time.The surgeon should choose a reasonable operation based on his/her own experience.

Objective     To investigate the safety and feasibility of day surgery for patients with palmar hyperhidrosis based on the principles of enhanced recovery after surgery (ERAS). Methods     We retrospectively reviewed the medical records of consecutive patients who underwent endoscopic thoracic sympathicotomy (ETS) in the First Affiliated Hospital of Xi'an Jiaotong University from March 2020 to December 2021. Patients were divided into a day surgery group and a conventional group according to their perioperative management methods. The patients in the day surgery group underwent an optimized perioperative procedure under the guidance of ERAS, and were ventilated with a laryngeal or face mask during the operation. The patients in the conventional group completed the preoperative examination, operation and postoperative observation according to the conventional procedures, and were intubated with a single-lumen endotracheal tube. The demographic characteristics, operation time, hospital stay, postoperative complications, and hospitalization cost were compared between the two groups. Results     Finally 172 patients were collected, including 90 males and 82 females, with an average age of 25.97±7.43 years. There were 86 patients in each group. All patients ceased suffering from palmar sweating after surgery. No patient experienced massive bleeding or conversion to thoracotomy. There was no statistical difference in operation time between the two groups (P=0.534). Patients in the day surgery group were discharged within 24 hours. The average hospital stay in the conventional group was 2.09±0.41 days. Incidence of postoperative respiratory complications, and the hospitalization cost of the day surgery group were significantly lower than those of the conventional group (P<0.001). The satisfaction rate in both groups was greater than 95%. Conclusion     Day surgery for patients with palmar hyperhidrosis based on the principles of ERAS is safe and feasible, which can reduce postoperative complications, shorten the length of hospital stay and save the cost of hospitalization.

Cardiovascular disease has become a major public health problem to be solved due to its high incidence rate,high mortality and heavy economic and social burden.Mitochondrial quality control is the cornerstone of maintaining mitochondrial homeostasis and plays an important role in the occurrence and progression of cardiovascular diseases.Some studies have found that Sirt1/Sirt3 signal is involved in the mechanism of myocardial mitochondrial quality control,and has gradually become an important target for cardiovascular disease prevention and treatment.At the same time,research shows that traditional Chinese medicine can regulate the quality control of myocardial mitochondria based on Sirt1/Sirt3 signal,and improve cardiovascular disease,but research is still insufficient.Therefore,this article reviews the research related to the influence of Sirt1/Sirt3 signal on the mitochondrial quality control of cardiovascular disease and proposes new ideas in combination with traditional Chinese medicine,with a view to providing a basis and direction for the research on the target of cardiovascular disease and the mechanism of traditional Chinese medicine in the prevention and treatment of cardiovascular disease.

Objective:The extensive development of anatomical pulnonary segmentectomy requires thoracic surgeons to be familiar with the anatomical variations of the lung segment. The purpose of this study is to analyze the anatomical patterns of the right upper lobe lung segment using three-dimensional reconstruction, and to count rare variant types.Methods:From October 2017 to March 2020, 101 patients with small pulmonary nodules who were undergo segmental resection in our center were subjected to preoperative three-dimensional reconstruction of the lung structure, and the reconstruction data was retained for the statistics and analysis of the anatomical structure in the right upper lung lobe.Results:The right upper lobe bronchus is the most common with three branches(77/101), followed by two branches(16/101) and four branches(7/101). The two branches(70/101) of the right upper lobe pulmonary artery are the most common, followed by single branch(19/101) and three branches(11/101). In rare cases, four branches(1/101 cases) can be seen. The two branches(63/101) of the right upper pulmonary vein were the most common, followed by three branches(32/101) and single branch(6/101). In addition, a total of 12 rare mutations were counted. There were 2 variants in the bronchus, totaling 2 cases; 4 rare variants in the pulmonary artery, 13 cases total; 6 rare variants in the pulmonary vein, 10 cases total.Conclusion:The lung anatomy is complex and has many variations. The surgeon should fully grasp the anatomical structure of the lung segment of the patient's operating area before surgery, the data in this article will be a valuable reference for thoracic surgeons to carry out the upper right lobe segmentectomy.

Objective    To analyze the effect of different drainage modes on the postoperative thoracic drainage after video-assisted thoracoscopic surgery for radical resection of lower lung carcinoma. Methods    A total of 183 patients with non-small cell lung cancer who received biportal thoracoscopic anatomical lower lobectomy combined with mediastinal lymph node dissection in the First Affiliated Hospital of Xi'an Jiaotong University from August 2017 to August 2019 were enrolled, including 113 males and 70 females, aged 31-77 (56.5±6.4) years. The patients were randomly divided into three groups, including an anterior axillary line group, a mid-axillary line group and a modified anterior axillary line group. Clinical efficacy of the three groups was compared. Results    No significant difference among these three groups in terms of gender, age, surgical site, pathological type, pathological staging, postoperative chest wall subcutaneous emphysema, postoperative pain score, and postoperative hospital stay was found (P>0.05). There were significant differences among the patients in terms of postoperative pleural effusion, re-insertion of chest tube or aspiration, total liquid quantity of thoracic drainage, drainage time and chest wall incision stitches time (P<0.05). The anterior axillary line group had higher risk of postoperative pleural effusion than the other groups (P<0.05). The occurrence of postoperative pleural effusion and rate of reposition of chest tube or aspiration were significantly reduced in the modified anterior axillary line group (P<0.05). Conclusion    Chest drainage tube with large diameter (24F) in the 5th intercostal space of the anterior axillary line combined with another micro-tube (8.5F) in the 7th or 8th intercostal space of the inferior scapular angle line can shorten drainage time to reduce postoperative pain, reduce the occurrence of postoperative pleural effusion, and shorten the time of surgical incision stitches.

Objective To summarize the experience of perioperative treatment of lung transplantation for end-stage lung disease. Methods Perioperative clinical data of 7 recipients undergoing lung transplantation were retrospectively analyzed, including 3 cases with bilateral lung transplantation and 4 cases with unilateral lung transplantation. The perioperative status and clinical prognosis of lung transplantation recipients were observed. Results The operation time of 7 lung transplantation recipients was (344±133) min. Cold ischemia time was (236±74) min in 4 cases of single-lung transplantation and (480±120) min in 3 cases of bilateral-lung transplantation. The length of Intensive care unit(ICU) stay was 21 (13-25) d and the length of hospital stay was 101 (64-117) d. In the first 3 d after surgery, the daily fluid output was significantly larger than the fluid input (all P < 0.05). The arterial oxygen partial pressure (PaO₂) of lung transplantation recipients in the first 3 d after surgery was significantly elevated than preoperative level (all P < 0.05), whereas the arterial carbon dioxide pressure (PaCO₂) did not significantly change (all P > 0.05). All recipients had pulmonary bacterial infection after lung transplantation, including 3 cases complicated with fungal infection. One recipient underwent exploratory thoracotomy for hemostasis due to active thoracic bleeding after operation, 1 recipient suffered from primary graft dysfunction (PGD) and 4 recipients received secondary endotracheal intubation. Two cases died after operation, 1 case died of septicemia caused by multidrug-resistant acinetobacter baumannii, the other case died of rejection reaction after self-terminating use of immunosuppressive agents. The remaining 5 cases were successfully discharged and recovered well. The longest survival period was 3.1 years. Conclusions In the perioperative management of lung transplantation, it has great significance to hold the surgical indications, monitor and manage postoperative refined fluid and hemodynamics, implement the strategy of protective pulmonary ventilation, and early diagnose and treat severe postoperative complications for the recipients of lung transplantation to safety through the perioperative period.
