The culture of suspended Vero cells is facing difficulties such as low cell viability and long doubling time. To investigate the main reasons for the slow growth and low viability of suspended Vero cells, this study conducted transcriptomic analysis of suspended Vero cells (Vero-XF) and adherent Vero cells (Vero-AD) to screen the differentially expressed genes (DEGs) affecting the growth of suspended cells. In addition, epidermal growth factor (EGF) was supplemented to the culture system to improve the growth of Vero-XF. The results showed that compared with the Vero-AD group, the Vero-XF group had 7 376 significant DEGs. Kyoto encyclopedia of genes and genomes enrichment analysis revealed that the DEGs were mainly enriched in the autophagy and mitophagy pathways. Eleven DEGs were selected and verified by quantitative real-time PCR, which showed up-regulated expression of ATG9B, WIPI2, LAMP2, OPTN, Rab7a, and DEPTOR and down-regulated expression of ATG4D, being consistent with the results of transcriptomic analysis. In addition, the Vero-XF group showed significantly up-regulated expression of ATG101, ATG2A, and STX17 and insignificant change in the expression of NBR1, compared with the Vero-AD group. The protein levels of LC3 and P62 in Vero-XF and Vero-AD were determined by Western blotting, which showed up-regulated expression of LC3Ⅱ/Ⅰ and down-regulated expression of P62 in Vero-XF, indicating a higher level of autophagy. Finally, the exogenous supplementation of EGF at 10, 20, and 30 μg/L in the culture system reduced the autophagy level of Vero-XF by 22.35%, 48.15%, and 71.29%, increased the specific growth rate by 15.48%, 33.33%, and 57.14%, and decreased the apoptosis rate by 2.84%, 15.46%, and 16.23%, respectively. The results of this study preliminarily reveal that the activation of autophagy is one of the reasons for the slow growth of Vero-XF, which provides reference for the subsequent culture of suspended Vero cells.

Hiatal hernia (HH) is a common benign disease in the digestive system, where the stomach or other internal organs bulges and displaces into posterior mediastinum through the esophageal hiatus on the diaphragm, often accompanied by symptoms such as heartburn, acid reflux, and chest pain. Patients with symptoms that are unresponsive to medical treatment require surgical intervention for relief. In recent years, robotic-assisted surgery (RAS) has rapidly advanced, offering precise manipulation, three-dimensional visualization, and a flexible wrist-turning robotic arm, capable of filtering out hand tremors. These advantages have led to the increasing use of RAS in HH repair procedures. This article provides a summary and analysis of RAS for the treatment of HH.

Objective:To investigate the changes in plasma ghrelin and influencing factors of weight loss effects after laparoscopic sleeve gastrectomy combined with fundoplication surgery (LSGFD).Methods:The retrospective cohort study was conducted. The clinical data of 115 obesity patients who were admitted to the People′s Hospital of Xinjiang Uygur Autonomous Region from April to June 2023 were collected. There were 37 males and 78 females, aged (37±9)years. Of 115 pati-ents, 93 cases undergoing laparoscopic sleeve gastrectomy (LSG) were divided into the LSG group, and 22 cases undergoing LSGFD were divided into the LSGFD group. Measurement data with normal distribution were represented as Mean± SD, and the independent sample t test was used for com-parison between groups. Count data were described as absolute numbers, and the chi-square test was used for comparison between groups. Repeated measurement data were analyzed using the repeated ANOVA, and their variances were tested using a spherical test. The Logistic regression model was used for univariate and multivariate analyses. Results:(1) Changes in preoperative and postoperative plasma ghrelin in two groups of patients. The plasma ghrelin of patients at preopera-tive and postoperative 6 months changed from (16±14)×10 2 ng/L to (10±4)×10 2 ng/L in the LSG group and changed from (12±11)×10 2 ng/L to (11±3)×10 2 ng/L in the LSGFD group. There was no significant difference in the time effect, inter group effect, and interaction effect of changes in plasma ghrelin between the LSG group and the LSGFD group before and after surgery at 6 months ( Ftime=2.199, Fgroup=0.001, Finteraction=0.793, P>0.05).

There was a significant difference in fasting blood glucose in the LSG group before and after surgery at 6 months ( t=2.675, P<0.05), and there was no significant difference in fasting blood glucose in the LSGFD group before and after surgery at 6 months ( t=1.074, P>0.05). ⑤ There were significant differences in the inter group effect and interaction effect of changes in triglyceride between the LSG group and the LSGFD group before and after surgery at 6 months ( Fgroup=8.419, Finteraction=3.180, P<0.05), and there was no significant diffe-rence in the time effect of changes in triglyceride between the LSG group and the LSGFD group before and after surgery at 6 months ( Ftime=1.398, P>0.05). Results of individual effect shown that there was no significant difference in triglyceride in the LSG group or the LSGFD group before and after surgery at 3 months ( F=2.956, 3.248, P>0.05), and there were significant differences in trigly-ceride in the LSG group or the LSGFD group after surgery at 1 month and 6 months ( F=14.152, 3.477, P<0.05). There was a significant difference in triglyceride in the LSG group before and after surgery at 6 months ( t=3.164, P<0.05), and there was no significant difference in triglyceride in the LSGFG group before and after surgery at 6 months ( t=0.023, P>0.05). ⑥ There were significant differences in the time effect and inter group effect of changes in total cholesterol between the LSG group and the LSGFD group before and after surgery at 6 months ( Ftime=3.662, Fgroup=7.591, P<0.05), and there was no significant difference in the interaction effect of changes in total cholesterol between the LSG group and the LSGFD group before and after surgery at 6 months ( Finteraction=0.626, P>0.05).

There were significant differ-ences in uric acid in the LSG group or the LSGFG group before and after surgery at 6 months ( t=6.152, 3.660, P<0.05). (3) Analysis of influencing factors on postoperative weight loss effects. Results of multivariate analysis showed that preoperative BMI, postoperative 6 months plasma ghrelin were independent protective factors for postoperative weight loss effects ( odds ratio=0.881, 0.673, 95% confidence interval as 0.817-0.950, 0.577-0.787, P<0.05). Conclusions:The decrease in plasma ghrelin in patients after LSGFD is not as obvious as that in patients after LSG, but it can achieve the same weight loss and metabolic improvement effects as after LSG. The lower preoperative BMI and postoperative 6 months plasma ghrelin are independent protective factors for postoperative weight loss effects.

Foregut surgery has emerged as a new discipline in recent years,gaining attention at home and abroad.It mainly focuses on benign diseases of the stomach and esophagus,covering conditions such as gastroesophageal reflux disease,achalasia,and bariatric metabolic surgery.However,in some countries,foregut surgery also includes malignant diseases,such as esophageal and gastric cancers.Robotic surgery,one of the most advanced techniques available,is increasingly applied in clinical practice.The unique ergonomic design of robotic surgical systems allows surgeons to control the instruments with greater precision and finesse,thereby minimizing damage to surrounding vital tissues and organs.Robotic surgery is gradually becoming a major focal point in the field of anterior foregut surgery.However,its curr-ent limitations in China include high equipment and maintenance costs,as well as strict requirements for operator qualifications and operating room conditions.As robotic technology continues to develop and improve,it is expected that robot-assisted surgery will play an increasingly important role in foregut surgery,helping doctors improve the quality of surgery and provide better treatment outcomes for patients.

Objective:The study aimed to analyze the clinical and endoscopic characteristics of adult celiac disease (CD) to provide a scientific basis for more effective CD diagnosis and treatment.Methods:In this cross-sectional study, the clinical and endoscopic data of 96 adult CD patients treated in the Department of Gastroenterology of the People′s Hospital of Xinjiang Uygur Autonomous Region from March 2016 to December 2021 were retrospectively collected and analyzed.Results:A total of 96 CD patients were diagnosed, including 33 men and 63 women. The average age was 47±14 years (range, 18-81 years). The disease occurred mainly in the age group of 31-60 years. The median course of the disease was 2.0 (0.2-40.0) years. There were 41 (42.7%) classical and 55 (57.3%) non-classical CD patients. All patients with classical CD showed chronic diarrhea, often accompanied by abdominal pain (46.3%, 19/41), abdominal distension (17.1%, 7/41), anemia (65.9%, 27/41), and chronic fatigue (48.8%, 20/41). The main manifestations of non-classical CD were chronic abdominal pain (58.2%, 32/55), abdominal distension (32.7%, 18/55), anemia (40.0%, 22/55), and osteopenia/osteoporosis (38.2%, 21/55). Compared with non-classical CD, anemia developed more frequently in classical CD, and the difference was statistically significant ( P = 0.012). The incidence of complications in CD patients was 36.5% (35/96), and the main complications were thyroid disease (19.8%, 19/96), connective tissue disease (6.2%, 6/96), and kidney disease (6.2%, 6/96). There was no significant difference between classical and non-classical CD ( P>0.05). The frequency of endoscopic manifestations in CD patients was 84.4% (81/96). Duodenal bulb endoscopy showed nodular changes (72.9%, 70/96), grooved changes (10.4%, 10/96), and focal villous atrophy (9.4%, 9/96). The main manifestations of descending endoscopy were the decrease, flattening, or disappearance of duodenal folds (43.8%, 42/96), scallop-like changes (38.5%, 37/96), and nodular changes (34.4%, 33/96). Conclusions:Adult CD patients are mostly female. CD occurred mainly in the age group of 31-60 years. The clinical manifestations were mainly those of non-classical CD. Some patients often had other autoimmune diseases. Patients with characteristic endoscopic manifestations should be warned about the possibility of developing CD. Clinicians should strengthen the understanding of CD and reduce the related rates of missed diagnosis.

Heart failure with preserved ejection fraction (HFpEF) displays normal or near-normal left ventricular ejection fraction, diastolic dysfunction, cardiac hypertrophy, and poor exercise capacity. Berberine, an isoquinoline alkaloid, possesses cardiovascular benefits. Adult male mice were assigned to chow or high-fat diet with L-NAME ("two-hit" model) for 15 weeks. Diastolic function was assessed using echocardiography and noninvasive Doppler technique. Myocardial morphology, mitochondrial ultrastructure, and cardiomyocyte mechanical properties were evaluated. Proteomics analysis, autophagic flux, and intracellular Ca²⁺ were also assessed in chow and HFpEF mice. The results show exercise intolerance and cardiac diastolic dysfunction in "two-hit"-induced HFpEF model, in which unfavorable geometric changes such as increased cell size, interstitial fibrosis, and mitochondrial swelling occurred in the myocardium. Diastolic dysfunction was indicated by the elevated E value, mitral E/A ratio, and E/e' ratio, decreased e' value and maximal velocity of re-lengthening (-dL/dt), and prolonged re-lengthening in HFpEF mice. The effects of these processes were alleviated by berberine. Moreover, berberine ameliorated autophagic flux, alleviated Drp1 mitochondrial localization, mitochondrial Ca²⁺ overload and fragmentation, and promoted intracellular Ca²⁺ reuptake into sarcoplasmic reticulum by regulating phospholamban and SERCA2a. Finally, berberine alleviated diastolic dysfunction in "two-hit" diet-induced HFpEF model possibly because of the promotion of autophagic flux, inhibition of mitochondrial fragmentation, and cytosolic Ca²⁺ overload.

Clinical application of doxorubicin (DOX) is heavily hindered by DOX cardiotoxicity. Several theories were postulated for DOX cardiotoxicity including DNA damage and DNA damage response (DDR), although the mechanism(s) involved remains to be elucidated. This study evaluated the potential role of TBC domain family member 15 (TBC1D15) in DOX cardiotoxicity. Tamoxifen-induced cardiac-specific Tbc1d15 knockout (Tbc1d15^CKO) or Tbc1d15 knockin (Tbc1d15^CKI) male mice were challenged with a single dose of DOX prior to cardiac assessment 1 week or 4 weeks following DOX challenge. Adenoviruses encoding TBC1D15 or containing shRNA targeting Tbc1d15 were used for Tbc1d15 overexpression or knockdown in isolated primary mouse cardiomyocytes. Our results revealed that DOX evoked upregulation of TBC1D15 with compromised myocardial function and overt mortality, the effects of which were ameliorated and accentuated by Tbc1d15 deletion and Tbc1d15 overexpression, respectively. DOX overtly evoked apoptotic cell death, the effect of which was alleviated and exacerbated by Tbc1d15 knockout and overexpression, respectively. Meanwhile, DOX provoked mitochondrial membrane potential collapse, oxidative stress and DNA damage, the effects of which were mitigated and exacerbated by Tbc1d15 knockdown and overexpression, respectively. Further scrutiny revealed that TBC1D15 fostered cytosolic accumulation of the cardinal DDR element DNA-dependent protein kinase catalytic subunit (DNA-PKcs). Liquid chromatography-tandem mass spectrometry and co-immunoprecipitation denoted an interaction between TBC1D15 and DNA-PKcs at the segment 594-624 of TBC1D15. Moreover, overexpression of TBC1D15 mutant (∆594-624, deletion of segment 594-624) failed to elicit accentuation of DOX-induced cytosolic retention of DNA-PKcs, DNA damage and cardiomyocyte apoptosis by TBC1D15 wild type. However, Tbc1d15 deletion ameliorated DOX-induced cardiomyocyte contractile anomalies, apoptosis, mitochondrial anomalies, DNA damage and cytosolic DNA-PKcs accumulation, which were canceled off by DNA-PKcs inhibition or ATM activation. Taken together, our findings denoted a pivotal role for TBC1D15 in DOX-induced DNA damage, mitochondrial injury, and apoptosis possibly through binding with DNA-PKcs and thus gate-keeping its cytosolic retention, a route to accentuation of cardiac contractile dysfunction in DOX-induced cardiotoxicity.

Gastroesophageal reflux disease (GERD) is one of the common gastrointestinal diseases. The treatment options for GERD includes lifestyle changes, medication, and surgery. With the development of surgical technology, minimally invasive surgery has become more and more widely used in clinical practice due to its advantages such as less trauma and rapid postoperative recovery. Laparoscopic fundoplication is the standard surgical treatment for GERD. Due to the postoperative complications of laparoscopic fundoplication, a variety of new alternative minimally invasive surgery methods, which are expected to provide new treatment options for GERD patients, have emerged recently. Surgical minimally invasive procedures include magnetic sphincter augmentation (MSA), bariatric surgery, and lower esophageal sphincter electric stimulating therapy (LES-EST). Endoscopic minimally invasive procedures include transoral incisionless fundoplication (TIF), Stretta radiofrequency ablation, and anti-reflux mucosectomy (ARMS). This article mainly describes the current status of minimally invasive surgical treatment of GERD.

Objective:To evaluate the efficacy and safety of video-assisted thoracoscopic surgery (VATS) and thoracotomy in the treatment of pulmonary echinococcosis.Methods:Pubmed, ScienceDirect, Medline, Wanfang Data Knowledge Service Platform, China National Knowledge Infrastructure (CNKI) and VIP Chinese Journal Service Platform were searched by computer from the earliest publication time of the documents included in the database to August 2020. Comparative studies on VATS and thoracotomy in the treatment of pulmonary echinococcosis were included and the quality was evaluated. The data were combined and analyzed by RevMan 5.3 software.Results:Eleven articles were finally included, including two randomized controlled trials (RCT) articles, and the rest were case-control studies. A total of 878 patients were included, including 447 in VATS group and 431 in thoracotomy group. The results of meta analysis showed that compared with thoracotomy group, VATS operation time [ MD (95% CI): - 28.59 (- 41.79, - 15.39)], intraoperative blood loss [ MD (95% CI): - 35.83 (- 49.65, - 22.01)], postoperative drainage volume [ MD (95% CI): - 94.83 (- 150.55, - 39.01)], postoperative catheterization time [ MD (95% CI): - 2.26 ( - 2.94, - 1.59)], hospital stay [ MD (95% CI): - 4.59 (- 6.51, - 2.67)], and postoperative complications [ MD (95% CI): 0.48 (0.32, 0.73)] in VATS group were significantly lower ( P < 0.05). There was no significant difference in postoperative recurrence between VATS group and thoracotomy group [ MD (95% CI): 0.75 (0.26, 2.16), P > 0.05]. Conclusions:Compared with thoracotomy, VATS in the treatment of pulmonary echinococcosis has the advantages of shorter operation time, less intraoperative blood loss, less postoperative drainage volume, shorter postoperative catheterization time and fewer postoperative complications. VATS is a safe and effective surgical method for the treatment of pulmonary echinococcosis.

ObjectiveTo determine the current status and characteristics of tuberculosis （TB） registration and treatment in Kashgar， and to provide scientific evidence for targeted prevention and control measures in future. MethodsKashgar registered TB cases information in 2011 to 2020 was exported from the National Tuberculosis Management Information System. Descriptive epidemiological analysis was conducted using Stata 12.0. ResultsFrom 2011 to 2020， number of Kashgar registered TB patients showed rising trend， followed by a falling one. Average proportion of annual decline in registered TB incidence was 40.48% from 2018 to 2020. From 2011 to 2016， number of registered TB patients in women was always higher than that in men， with a gender ratio （male ： female） of about 0.90. In 2017， the gender ratio was 1.00. From 2018 to 2020， the gender ratios were 1.05， 1.20， and 1.12， respectively. Moreover， number of registered TB cases increased with age （χ²=547.79， P<0.001）. Proportion of registered TB cases was relatively large in Shache County （16.43%‒23.64%）， Yengisar County （9.51%‒13.87%） ， Kashgar City （8.11%‒11.40%）， Yecheng County （6.98%‒13.40%） and Bachu County（4.92%‒16.65%）. Proportion of recurrent TB cases in Kashgar had increased to 27.29%， 20.77% and 28.39% in 2018， 2019 and 2020， respectively. Multivariate analysis showed that age， drug resistance， calendar year and etiological diagnosis were significantly correlated with the proportion of recurrent cases （all P<0.05）. ConclusionSince 2018， TB incidence has decreased significantly due to the increasing efforts for identification and treatment of TB cases. However， Kashgar remains facing a high TB incidence. TB cases that are elderly， drug-resistant and positive for pathogen are susceptible to recurrent treatment. In future， targeted prevention and control measures should be improved for these groups.
