Background: Hearing loss (HL) is one of the most common sensory disorders, affecting over 5-8% of the world's population. Approximately half of HL cases are attributed to genetic factors. In hereditary deafness, about 75-80% is inherited through autosomal recessive inheritance, and common pathogenic genes include GJB2 and SLC26A4. Pathogenic variants in the SLC26A4gene are the leading cause of hereditary hearing loss in humans, second only to the GJB2 gene. Variants in the SLC26A4gene cause hearing loss, which can be non-syndromic autosomal recessive deafness (DFNB4, OMIM #600791) associated with enlarged vestibular aqueduct (EVA) or Pendred syndrome (Pendred, OMIM #605646). DFNB4 is characterized by sensorineural hearing loss combined with EVA or less common cochlear malformation defect. Pendred syndrome is characterized by bilateral sensorineural hearing loss with EVA and an iodine defect that can lead to thyroid goiter. Currently, it is known that EVA is associated with variants in the SLC26A4 gene and is a penetrant feature of SLC26A4-related HL. Predominant mutations in these genes differ significantly across populations. For instance, predominant SLC26A4 mutations differ among populations, including p.T416P and c.1001G>A in Caucasians, p.H723R in Japanese and Koreans, and c.919-2A>G in Han Taiwanese and Han Chinese. On the other hand, there has been no study of hearing loss related to SLC26A4 gene variants among Mongolians, which is the basis of our research. Aim: We aimed to identify the characteristics of the SLC26A4 gene variants in Mongolian people with Enlarged vestibular aqueduct and Mondini malformation. Materials and Methods: In 2022-2024, We included 13 people with hearing loss and enlarged vestibular aqueduct, incomplete cochlea (1.5 turns of the cochlea with cystic apex- incomplete partition type II- Mondini malformation) were examined by CT scan of the temporal bone in our study. WES (Whole exome sequencing) analysis was performed in the Genetics genetic-laboratory of the National Taiwan University Hospital. Results: Genetic analysis revealed 26 confirmed pathogenic variants of bi-allelic SLC26A4 gene of 8 different types in 13 cases, and c.919-2A>G variant was dominant with 46% (12/26) in allele frequency, and c.2027T>A (p.L676Q) variant 19% (5/26), c.1318A>T(p.K440X) variant 11% (3/26), c.1229C>T (p.T410M) variant 8% (2/26) ) , c.716T>A (p.V239D), c.281C>T (p.T94I), c.1546dupC, and c.1975G>C (p.V659L) variants were each 4% (1/26)- revealed. Two male children, 11 years old (SLC26A4: c.919-2A>G) and 7 years old (SLC26A4: c.919-2A>G:, SLC26A4: c.2027T>A (p.L676Q))had history of born normal hearing and progressive hearing loss. Conclusions 1. 26 variants of bi-allelic SLC26A4 gene mutation were detected in Mongolian people with EVA and Mondini malformation, and c.919-2A>G was the most dominant allele variant, and rare variants such as c.1546dupC, c.716T>A (p.V239D) were detected. 2. Our study shows that whole-exome sequencing (WES) can identify gene mutations that are not detected by polymerase chain reaction (PCR) or NGS analysis.

Platelets have long been recognized as key players in hemostasis and thrombosis; however, there is growing evidence that they are also involved in cancer. Preclinical and clinical studies have shown that platelets can promote tumorigenesis and metastasis through various crosstalks between platelets and cancer cells. Platelets play an active role in all stages of tumorigenesis, including tumor growth, tumor cell extravasation, and metastasis. In addition, thrombocytosis in cancer patients is associated with poor patient survival. Platelets are also well-placed to coordinate local and distant tumor-host interactions due to the a- bundance of microparticles and exosomes. Therefore, antitumor drugs targeting platelets have great development and application prospects. The following will review the research progress of anti-tumor drugs targeting platelets.

Objective:To evaluate the effect of ultrasound-guided subserratus anterior plane block on postoperative analgesia in patients un-dergoing laparoscopic radical gastrectomy.Methods:Sixty patients who underwent elective laparoscopic radical gastrectomy were enrolled between May 2022 and October 2023 at Tianjin Medical University Cancer Institute&Hospital.Patients were assigned into two groups us-ing a random number table method:the control(group C)and the ultrasound-guided serratus anterior plane block(SAPB)(group S).Patient-controlled intravenous analgesia(PCIA)was administered at the end of the surgery.After surgery,visual analogue scale(VAS)of static pain scores was evaluated at 1,6,12,24,and 48 hours.PCIA pump was started at the VAS pain score≥4 after surgery,and sufentanil 0.1μg/kg was intravenously injected when the efficacy was inadequate.The requirement for PCIA use,time to first postoperative anal exhaust,first postoperative out-of-bed activity,first oral intake,and the duration of hospitalization stay were recorded for the two groups.Results:VAS scores were significantly lower at postoperative 1,6,and 12 h in group S than in group C(P<0.05).Additionally,the number of effective uses of PCIA,and rescue analgesia were significantly lower in group S[(6.1±0.4)(2)]than in group C[(18.6±1.4)(17)](P<0.001).The time to first postoperative anal exhaust,first postoperative out-of-bed activity,first oral intake,and duration of hospital stay were shortened in group S than in group C(P<0.05).There were no significant differences in other parameters between these two groups.Conclusion:Ultrasound-guided SAPB can reduce postoperative pain and facilitate fast recovery in laparoscopic radical gastrectomy patients.

Objective:To evaluate the effect of ultrasound-guided internal branch of superior laryngeal nerve(ibSLN) block on the quality of anesthesia recovery in the patients undergoing intracranial tumor surgery.Methods:The data from patients of either gender, aged 18-65 yr, with a body mass index of 18-28 kg/m 2, who underwent intracranial tumor surgery from December 2022 to October 2023, were retrospectively collected. Patients were divided into control group (group C) and ultrasound-guided ibSLN block group (group U). Bilateral ibSLN block was performed with 0.375% ropivacaine hydrochloride 2 ml.The tracheal extubation time, emergence time, development of cardiovascular events within 15 min after extubation, emergence agitation, Ramsay sedation score, Steward recovery score, visual analogue scale scores at 10 min after extubation and development of postoperative sore throat and hoarseness in postanesthesia care unit were recorded. Results:Compared with group C, the incidence of emergence agitation, Ramsay sedation score, visual analogue scale scores and sore throat were significantly decreased, the incidence of hoarseness was increased ( P<0.05), and no significant change was found in the extubation time, emergence time and Steward recovery score in group U( P>0.05). No hypertension, hypotension, tachachycardia and bradycardia were found in two groups. Conclusions:Ultrasound-guided ibSLN block can improve the quality of anesthesia recovery in the patients undergoing intracranial tumor surgery.

Objective:To investigate the surgical situations and perioperative outcome of pancreaticoduodenectomy in Jiangsu Province and the influencing factors for postoperative 90-day mortality.Methods:The retrospective case-control study was conducted. The clinicopathological data of 2 886 patients who underwent pancreaticoduodenectomy in 21 large tertiary hospitals of Jiangsu Quality Control Center for Pancreatic Diseases, including The First Affiliated Hospital of Nanjing Medical University, from March 2021 to December 2022 were collected. There were 1 732 males and 1 154 females, aged 65(57,71)years. Under the framework of the Jiangsu Provincial Pancreatic Disease Quality Control Project, the Jiangsu Quality Control Center for Pancreatic Diseases adopted a multi-center registration research method to establish a provincial electronic database for pancrea-ticoduodenectomy. Observation indicators: (1) clinical characteristics; (2) intraoperative and post-operative conditions; (3) influencing factors for 90-day mortality after pancreaticoduodenectomy. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(IQR), and comparison between groups was conducted using the Mann-Whitney U test. Count data were expressed as absolute numbers or constituent ratio, and comparison between groups was conducted using the chi-square test, continuity correction chi-square test and Fisher exact probability. Maximal Youden index method was used to determine the cutoff value of continuous variables. Univariate analysis was performed using the corresponding statistical methods based on data types. Multivariate analysis was performed using the Logistic multiple regression model. Results:(1) Clinical characteristics. Of the 2 886 patients who underwent pancreaticoduodenectomy, there were 1 175 and 1 711 cases in 2021 and 2022, respectively. Of the 21 hospitals, 8 hospitals had an average annual surgical volume of <36 cases for pancreaticoduodenectomy, 10 hospitals had an average annual surgical volume of 36-119 cases, and 3 hospitals had an average annual surgical volume of ≥120 cases. There were 2 584 cases performed pancreaticoduodenectomy in thirteen hospitals with an average annual surgical volume of ≥36 cases, accounting for 89.536%(2 584/2 886)of the total cases. There were 1 357 cases performed pancrea-ticoduodenectomy in three hospitals with an average annual surgical volume of ≥120 cases, accounting for 47.020%(1 357/2 886) of the total cases. (2) Intraoperative and postoperative conditions. Of the 2 886 patients, the surgical approach was open surgery in 2 397 cases, minimally invasive surgery in 488 cases, and it is unknown in 1 case. The pylorus was preserved in 871 cases, not preserved in 1 952 cases, and it is unknown in 63 cases. Combined organ resection was performed in 305 cases (including vascular resection in 209 cases), not combined organ resection in 2 579 cases, and it is unknown in 2 cases. The operation time of 2 885 patients was 290(115)minutes, the volume of intra-operative blood loss of 2 882 patients was 240(250)mL, and the intraoperative blood transfusion rate of 2 880 patients was 27.153%(782/2 880). Of the 2 886 patients, the invasive treatment rate was 11.342%(327/2 883), the unplanned Intensive Care Unit (ICU) treatment rate was 3.087%(89/2 883), the reoperation rate was 1.590%(45/2 830), the duration of postoperative hospital stay was 17(11)days, the hospitalization mortality rate was 0.798%(23/2 882), and the failure rate of rescue data in 2 083 cases with severe complications was 6.529%(19/291). There were 2 477 patients receiving postoperative 90-day follow-up, with the 90-day mortality of 2.705%(67/2477). The total incidence rate of complication in 2 886 patients was 58.997%(1 423/2 412). The incidence rate of severe complication was 13.970%(291/2 083). The comprehensive complication index was 8.7(22.6) in 2 078 patients. (3) Influencing factors for 90-day mortality after pancreaticoduodenectomy. Results of multivariate analysis showed that age ≥ 70 years, postoperative invasive treatment, and unplanned ICU treatment were independent risk factors for 90-day mortality after pancreaticoduodenectomy ( odds ratio=2.403, 2.609, 16.141, 95% confidence interval as 1.281-4.510, 1.298-5.244, 7.119-36.596, P<0.05). Average annual surgical volume ≥36 cases in the hospital was an independent protective factor for 90-day mortality after pancreaticoduodenectomy ( odds ratio=0.368, 95% confidence interval as 0.168-0.808, P<0.05). Conclusions:Pancreaticoduodenectomy in Jiangsu Province is highly con-centrated in some hospitals, with a high incidence of postoperative complications, and the risk of postoperative 90-day mortality is significant higher than that of hospitallization mortality. Age ≥ 70 years, postoperative invasive treatment, and unplanned ICU treatment are independent risk factors for 90-day motality after pancreaticoduodenectomy, and average annual surgical volume ≥36 cases in the hospital is an independent protective factor.

Objective:To investigate the influence of curative-intent resection with textbook outcomes of liver surgery (TOLS) on long-term prognosis of gallbladder carcinoma (GBC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 824 patients with GBC in the national multicenter database of Biliary Surgery Group of Elite Group of Chinese Journal of Digestive Surgery, who were admitted to 15 medical centers from January 2014 to January 2021, were collected. There were 285 males and 539 females, aged (62±11)years. According to the evalua-tion criteria of TOLS, patients were divided into those who achieved TOLS and those who did not achieve TOLS. Measurement data with normal distribution were represented as Mean± SD, and com-parison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data were conduc-ted using the Mann-Whitney U test. The Kaplan-Meier method was used to calculate survival rate and draw survival curve, and the Log-rank test was used for survival analysis. The COX stepwise regression model with backward Wald method was used for univariate and multivariate analyses. Results:(1) Achievement of TOLS. Of the 824 patients undergoing curative-intent resection for GBC, there were 510 cases achieving TOLS and 314 cases not achieving TOLS. (2) Follow-up. Of the 824 patients undergoing curative-intent resection for GBC, after excluding 112 deaths within 90 days after discharge, 712 cases were included for the survival analysis. The median follow-up time, median overall survival time and 5-year overall survival rate of the 510 patients achieving TOLS were 22.1(11.4,30.1)months, 47.6(30.6,64.6)months and 47.5%. The median follow-up time, median overall survival time and 5-year overall survival rate of the 202 patients not achieving TOLS were 14.0(6.8,25.5)months, 24.3(20.0,28.6)months and 21.0%. There was a significant difference in overall survival between patients achieving TOLS and patients not achieving TOLS ( χ2=58.491, P<0.05). (3) Analysis of factors influencing prognosis of patients. Results of multivariate analysis showed that TOLS, carcinoembryonic antigen (CEA), CA19-9, poorly differentiation of tumor, T2 stage of eighth edition of American Joint Committee on Cancer (AJCC) staging, T3 and T4 stage of eighth edition of AJCC staging, N1 stage of the eighth edition of AJCC staging, N2 stage of the eighth edition of AJCC staging, adjuvant therapy were independent factors influencing overall survival time of patients undergoing curative-intent resection for GBC ( hazard ratio=0.452, 1.479, 1.373, 1.612, 1.455, 1.481, 1.835, 1.978, 0.538, 95% c onfidence interval as 0.352-0.581, 1.141-1.964, 1.052-1.791, 1.259-2.063, 1.102-1.920, 1.022-2.147, 1.380-2.441, 1.342-2.915, 0.382-0.758, P<0.05). Conclusion:Patients under-going curative-intent resection for GBC with TOLS can achieve better long-term prognosis.

Objective To investigate the therapeutic effect of transcutaneous auricular vagus nerve stimulation(taVNS)on overweight/obesity patients,and to explore its central mechanism.Methods Twenty-six overweight/obesity patients were randomly divided into two groups,12 cases in the taVNS test group(shortened as the taVNS group)and 14 cases in the lifestyle intervention control group(shortened as the control group).The patients in the control group were treated with online lifestyle intervention of calorie-restricted diet(CRD),and the patients in the taVNS group were treated with taVNS on the basis of the intervention for the control group.The taVNS was performed on unilateral acupoints of spleen and endocrine,twice(in the morning and at evening)per day,for five days a week.The treatment for the two groups covered four weeks.The obesity indicators such as body weight,body mass index(BMI)and waist circumference of the patients in the two groups were observed before and after treatment.Moreover,the resting-state cerebral functional magnetic resonance imaging(fMRI)data of the patients were collected after treatment,and then the regulatory effect of taVNS on the regional homogeneity(ReHo)of local cerebral area of the patients was observed.Results(1)During the trial,one case in each group dropped off,and a total of 24 patients(including 13 cases in the control group and 11 cases in the taVNS group)were finally included in the statistical analysis of the observation indicators.(2)After treatment,the body weight,BMI and waist circumference of patients in the taVNS group were decreased compared with those before treatment(P＜0.05),while the obesity indicators in the control group only showed a downward trend compared with those before treatment,the differences being not statistically significant(P＞0.05).The improvement of the obesity indicators of body weight,BMI,and waist circumference in the taVNS group was significantly superior to that in the control group,and there were statistically significant differences in the post-treatment indicators and in the pre-and post-treatment difference values of the indicators between the two groups(P＜0.05 or P＜0.01).(3)After treatment,the taVNS group had greater ReHo values in the left prefrontal lobe and medial frontal gyrus than the control group,and the control group had greater ReHo value in the right parietal lobe than the taVNS group,which indicated that compared with the control group,the ReHo of the left prefrontal lobe and medial frontal gyrus in the taVNS group was increased and the ReHo of the right parietal lobe was decreased(Pvoxel＜0.001,Pcluster＜0.05,corrected by FWE level).Conclusion As a non-invasive treatment method,taVNS exerts certain efficacy for the treatment of overweight/obesity patients.The central response mechanism for treatment of obesity is probably related with the modulation of taVNS on the functional areas of left prefrontal lobe,medial frontal gyrus,and right parietal lobe of the patients.

Objective To explore the short-term efficacy of endovascular isolation treatment for type A aortic intramural hematoma(AIH)with pericardial effusion,and to discuss the endovascular isolation treatment strategy for type A AIH with pericardial effusion.Methods A total of 12 patients with type A AIH complicated by pericardial effusion,who were admitted to the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine of China between February 2018 and November 2021,were enrolled in this study.Before surgery,the intima of the ascending aorta was intact in all patients,but a rupture at the proximal intima of the aortic arch or the thoracic descending aorta was detected.All patients received endovascular isolation treatment.Among them,4 patients received endovascular isolation treatment within one week after the onset of disease,and 8 patients received selective operation after receiving conservative treatment for one week.The patients were followed up for one year.Results Among the patients who received endovascular isolation treatment within one week after the onset of disease,one patient recovered smoothly,two patients developed type A dissection within 3 months after surgery,and one died early after surgery.All the 8 patients,who received selective operation after receiving conservative treatment for one week,recovered smoothly.Conclusion For patients with type A AIH complicated by mild to moderate pericardial effusion,selective endovascular isolation treatment after receiving the conservative treatment to alleviate the ascending aortic hematoma can achieve ideal therapeutic effect.

AIM:To investigate the impact of hippocampal protein phosphatase 1 regulator subunit 17(Ppp1r17)down-regulation on drinking-related behavior in mice,and to explore the protein kinase B(PKB/AKT)/glyco-gen synthase kinase-3β(GSK-3β)/cAMP response element binding protein(CREB)signaling pathway of Ppp1r17 in the development of alcohol dependence.METHODS:Forty male C57BL/6J mice were randomly divided into four groups(n=10):control group,shPpp1r17① group,shPpp1r17② group and shPpp1r17③ group.The mRNA and protein expression levels in the hippocampal tissues were evaluated after 3 weeks of AAV-shPpp1r17 injection.Twenty male C57BL/6J mice were randomly divided into a control group and a shPpp1r17 group(n=10).An open-field test,conditioned place prefer-ence(CPP)test and righting reflex test were performed.Furthermore,the localization and expression of AAV-shPpp1r17 were detected after 3 weeks of AAV-shPpp1r17 injection.Twenty male C57BL/6J mice were randomly divided into four groups(n=5):the empty virus+water group,the empty virus+EtOH group,the shPpp1r17+water group and the shPpp1r17+EtOH group.The EtOH group mice drank 9%alcohol continuously for 30 d.The protein expression levels of Ppp1r17,p-AKT,AKT,p-GSK-3β,GSK-3β,p-CREB and CREB were detected by Western blot.RESULTS:(1)The results of qPCR showed that Ppp1r17 was successfully suppressed by shPpp1r17.(2)The behavioral results showed that the shPpp1r17 group mice exhibited enhanced exercise ability and reduced anxiety-like emotions,and the downregulation of Ppp1r17 increased CPP scores and reduced the sensitivity of the mice to alcohol.(3)Immunofluorescence showed that AAV-shPpp1r17 was specifically expressed in the hippocampus.(4)Western blot analysis revealed that Ppp1r17 and the p-AKT/AKT,p-GSK-3β/GSK-3β and p-CREB/CREB ratios were significantly increased after treatment of EtOH.Howev-er,the protein expression of Ppp1r17 was significantly reduced,and the AKT/GSK-3β/CREB pathway was activated after knockdown of Ppp1r17 in the hippocampus.CONCLUSION:Ppp1r17 may suppress CREB phosphorylation through the AKT/GSK-3β/CREB pathway,thereby influencing alcohol drinking preference and locomotor behavior in mice.
