Objective To analyse the clinical efficiency of endolymphatic sac surgery (ESS) in the management of Meniere’s disease (MD). Methods A retrospective analysis was conducted on 274 patients with MD who were hospitalized for treatment in Sun Yat-Sen Memorial Hospital, Sun Yat-Sen University from January 2009 to August 2023. All patients received lifestyle management and drug treatment such as diuretics. For those whose conditions were not well controlled 3 to 6 months after the initial treatment, intratympanic glucocorticoid (ITG) or ESS treatment was carried out. Six months after the treatment, the classes of vertigo relief and hearing changes in the patients were evaluated. After adjusting the confounding factors through propensity score matching (PSM), the impact of ESS on the prognosis of MD patients was evaluated. Results Among 274 patients, 194 and 80 patients underwent ITG and ESS, respectively. Eighty patients were enrolled into each group after PSM. Before and after PSM, the rate of patients reaching vertigo relief class A in ESS group was higher than that in the ITG group (P＝0.004); there was no significant difference in hearing preservation between the two groups. Kaplan-Meier curve analysis showed that vertigo relief in the ESS group was better than that in the ITG group (P=0.029); there was no statistically significant difference in hearing preservation between the two groups. Conclusion When the initial treatment for patients with MD is ineffective, choosing ESS is more beneficial than ITG for controlling vertigo.

Objective To investigate the feasibility of a "pericardial lining" modified Bentall procedure for the treatment of patients with aortic root aneurysm. Methods This was a retrospective study that consecutively enrolled patients treated at the Affiliated Suzhou Hospital of Nanjing Medical University, The Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University, and the First People's Hospital of Guangyuan from January 2023 to February 2024. Preoperative clinical data, imaging findings (including echocardiography and CT scans of the aortic root and the entire aorta), details of coronary artery management, surgical outcomes, and postoperative follow-up results were collected. All patients underwent the "pericardial lining" modified Bentall procedure: the aortic valve was replaced, and an autologous pericardial patch was divided into three equal leaflets based on the circumference of the aortic annulus measured by a valve sizer. These leaflets were then sutured to the aortic annulus. Fenestrations were created in two of the pericardial leaflets for anastomosis with the left and right coronary ostia. The pericardial leaflets were sutured to the wall of the aortic sinuses to form an integrated structure, thereby narrowing the sinus portion. A prosthetic vascular graft was anastomosed to the proximal and distal aorta, and no aortic root-to-right atrium shunt was created. Results A total of 5 patients, aged 37 to 68 years, were included. The preoperative Society of Thoracic Surgeons (STS) risk scores ranged from 2.8% to 3.9%. The diameter of the ascending aorta was 40-73 mm, the left ventricular end-diastolic diameter (LVEDD) was 45-71 mm, and the left ventricular ejection fraction (LVEF) was 47%-64%. Intraoperatively, the aortic cross-clamp time ranged from 85 to 180 min, and the cardiopulmonary bypass time ranged from 110 to 302 min. Postoperative follow-up echocardiography revealed that the ascending aortic diameter was 27-35 mm, LVEDD was 39-57 mm, and LVEF was 43%-61%. All surgeries were completed successfully with satisfactory immediate outcomes and no intraoperative complications. During the follow-up period, there was no mortality or reoperation. Conclusion For patients with aortic root aneurysm, the "pericardial lining" modified Bentall procedure yields satisfactory preliminary results, and the technique is demonstrated to be feasible.

Objective To explore the effects and action mechanism of miR-181c-5p on biological behaviors of pros-tate cancer cells.Methods The pathological relationship between BIRC5,miR-181c-5p and prostate cancer was analyzed based on prostate cancer data in TCGA database.The target binding site of miR-181c-5p and BIRC5 was analyzed by miRNA target gene prediction database,and was verified by double luciferase activity assay.The ex-pression of BIRC5 protein in miR-181 c-5p overexpression cells was detected by Western blot.The prostate cancer cells PC3 and DU145 were selected to construct cell line with miR-181c-5p overexpression(miR-181c-5p group)and its negative control(miR-NC group),and qRT-PCR verification was conducted.The cells proliferation[opti-cal density at 450 nm site(OD450 nm)]was detected by CCK-8.Distribution of cell cycles and apoptosis rate were detected by flow cytometry.Expressions of proliferation and apoptosis related proteins were detected by Western blot.The cell line with miR-181c-5p/BIRC5 overexpression was constructed(miR-181c-5p+BIRC5 group).Cells growth,distribution of cell cycles,apoptosis rate and expressions of related proteins were detected by the a-bove methods.Results The expression of BIRC5 was up-regulated in prostate cancer tissues,and it was higher in patients with high tumor invasion,lymph node metastasis and recurrence.Patients exhibiting high expression of BIRC5 demonstrated poor survival rates.The expression of miR-181c-5p was down-regulated in prostate cancer tis-sues.The level of miR-181c-5p was negatively correlated with BIRC5 level,and miR-181c-5p could inhibit BIRC5 expression.In PC3 and DU145,miR-181c-5p level in miR-181c-5p group was higher than that in miR-NC group(P＜0.05);OD450 nm and percentage of S-phase cells were lower than those in miR-NC group(P＜0.05),per-centage of cells in G0/G1 phase;apoptosis rate and expressions of BAX,caspase-3 and PARP proteins were higher than those in miR-NC group(P＜0.05);expressions of CDK2,CCNB1 and BCL-2 proteins were lower than those in miR-NC group(P＜0.05).The expression of BIRC5 protein and OD450 nm in miR-181 c-5p+BIRC5 group were higher than those in miR-181c-5p group(P＜0.05),percentage of cells in G0/G1 phase was lower than that in miR-181c-5p group(P＜0.05);percentage of S-phase cells was higher than that in miR-181c-5p group(P＜0.05);apoptosis rate was lower than that in miR-181c-5p group(P＜0.05);expressions of CDK2,CCNB1 and BCL-2 proteins were higher than those in miR-181c-5p group;expressions of BAX,caspase-3 and PARP proteins were lower than those in miR-181 c-5p group.Conclusion miR-181-5p can inhibit the proliferation of human pros-tate cancer cells by targeting BIRC5,block cells in G0/G,phase and promote cells apoptosis.

Objective:To investigate the clinical and gene variant characteristics of PCDH19 gene related epilepsy, and improve the ability of clinicians in early disease identification. Methods:The clinical data of 3 PCDH19 gene related epilepsy patients admitted to Children′s Hospital Affiliated to Zhengzhou University from October 2018 to August 2023 diagnosed by gene detection were reviewed and analyzed. Results:All the patients are female, and the onset age of seizure ranged in their infancy. Seizures in clusters and fever sensitivity were observed in all patients, and were very hard to control by single-drug treatment. Proband 1 was seizure-free after 2 kinds of anti-epileptic drug treatment, but with mild degree of intellectual disability. Proband 2 had refractory epilepsy with severe degree of intellectual disability. Proband 3 was seizure-free after 2 kinds of anti-epileptic drug treatment and without intellectual disability. In the first family, the proband carried heterozygous c.369C>G variant in the PCDH19 gene which was identified as de novo after parental validation. In the second family, the proband carried c.1652T>A variant inherited from her mother. In the third family, the proband carried c.278G>A variant inherited from her father. The 3 mutations had not been reported in the Human Gene Mutation Database. Conclusions:PCDH19 gene related epilepsy is one special kind of X-linked inherited epilepsy syndrome characterized by seizures in clusters and sensitivity to fever. And gene detection can help with early diagnosis and make rational clinical strategies in time. The variants c.369C>G, c.1652T>A and c.278G>A have enriched the gene variant spectrum of PCDH19.

Objective To investigate the expression of inositol polyphosphate 4-phosphatase type Ⅱ B(INPP4B)in colorectal cancer(CRC)and the relevant clinical significance,to determine the relationship between INPP4B and matrix metallopeptidase 7(MMP7)in CRC cells,and to make preliminary exploration of the effects of INPP4B on the proliferation and migration of CRC cells and mechanisms involved.Methods The TIMER2.0 and GEPIA2 databases were used to analyze the differences in INPP4B expression between cancer and para-cancerous tissues and the effects of such differences on the prognosis of CRC.The expression of INPP4B in 102 surgically resected CRC tumors was determined by immunohistochemistry(IHC),and the correlation between INPP4B and clinical pathological indicators was analyzed.In CRC cells with overexpressed/knocked-down INPP4B,the expression of INPP4B and MMP7 were examined by real time fluorogenic quantitative PCR,the protein expression of INPP4B was assessed by Western blot,cell proliferation was determined using the CellTiter 96? AQueous One assay,and cell migration and invasion were assessed using wound healing assay and real-time label-free dynamic cell analysis(RTCA).The LinkedOmics database was used to analyze signaling pathways related to INPP4B function,and the role of potential key molecules was validated at the cellular level.Results Analysis with the TIMER2.0 database and GEPIA2 database showed elevated INPP4B expression(colon adenocarcinoma[COAD]:2.30,rectal adenocarcinoma[READ]:2.33)in CRC compared to normal tissue(COAD:1.91,READ:1.89).IHC testing confirmed that INPP4B was upregulated in clinical CRC tissues and paracancerous tissues(P＜0.001).Cox regression model analysis showed that INPP4B(hazards ratio[HR]=1.457,95％confidence interval[CI]:1.003-2.115)affected the prognosis of CRC,and the Kaplan-Meier curve showed that patients with high INPP4B expression had shorter overall survival(P＜0.05).x2 test was performed to analyze the relationship between INPP4B expression and clinicopathological indexes,and it was found that high expression of INPP4B was correlated with lymph node metastasis(x2=3.997,P=0.046)and neural invasion(x2=8.511,P=0.004).In in vitro experiments,CRC cells overexpressing INPP4B showed a significantly increased cell proliferation and migration compared to the cells in the control group(P＜0.05).Analysis using the LinkedOmics database showed that INPP4B was correlated with extracellular matrix remodeling and cell migration.Pearson's correlation analysis showed that MMP7 was positively correlated with INPP4B(r=0.3782,P＜0.001).INPP4B overexpression or knockdown in vitro also led to the upregulation or the downregulation of MMP7 expression in CRC cells.Conclusion INPP4B is highly expressed in CRC tissues and significantly correlated with lymph node metastasis,neural invasion,and patient prognosis.MMP7 may mediate the role of INPP4B in promoting CRC cell migration and invasion.

Objective To explore the association between lipid profiles and left ventricular hypertrophy in a Chinese general population. Methods We conducted a retrospective observational study to investigate the relationship between lipid markers [including triglycerides, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein (HDL) cholesterol, non-HDL-cholesterol, apolipoprotein A-I, apolipoprotein B, lipoprotein[a], and composite lipid profiles] and left ventricular hypertrophy. A total of 309,400 participants of two populations (one from Beijing and another from nationwide) who underwent physical examinations at different health management centers between 2009 and 2018 in China were included in the cross-sectional study. 7,475 participants who had multiple physical examinations and initially did not have left ventricular hypertrophy constituted a longitudinal cohort to analyze the association between lipid markers and the new-onset of left ventricular hypertrophy. Left ventricular hypertrophy was measured by echocardiography and defined as an end-diastolic thickness of the interventricular septum or left ventricle posterior wall > 11 mm. The Logistic regression model was used in the cross-sectional study. Cox model and Cox model with restricted cubic splines were used in the longitudinal cohort. Results In the cross-sectional study, for participants in the highest tertile of each lipid marker compared to the respective lowest, triglycerides [odds ratio (OR): 1.250, 95％CI: 1.060 to 1.474], HDL-cholesterol (OR: 0.780, 95％CI: 0.662 to 0.918), and lipoprotein(a) (OR: 1.311, 95％CI: 1.115 to 1.541) had an association with left ventricular hypertrophy. In the longitudinal cohort, for participants in the highest tertile of each lipid marker at the baseline compared to the respective lowest, triglycerides [hazard ratio (HR): 3.277, 95％CI: 1.720 to 6.244], HDL-cholesterol (HR: 0.516, 95％CI: 0.283 to 0.940), non-HDL-cholesterol (HR: 2.309, 95％CI: 1.296 to 4.112), apolipoprotein B (HR: 2.244, 95％CI: 1.251 to 4.032) showed an association with new-onset left ventricular hypertrophy. In the Cox model with forward stepwise selection, triglycerides were the only lipid markers entered into the final model. Conclusion Lipids levels, especially triglycerides, are associated with left ventricular hypertrophy. Controlling triglycerides level potentiate to be a strategy in harnessing cardiac remodeling but deserve to be further investigated.

Objective:To assess the efficacy and safety of the combination therapy of camrelizumab, apatinib, nab-paclitaxel, and S-1 for patients with locally unresectable advanced gastric cancer.Methods:From September 1, 2019 to August 1, 2021, in Beijing Friendship Hospital Affiliated to Capital Medical University, 17 patients with advanced gastric cancer were enrolled in this prospective, single-arm study. All the enrolled patients received camrelizumab, nab-paclitaxel, apatinib and S-1 combination therapy (in each 21 days cycle, camrelizumab 200 mg intravenously, D1; nab-paclitaxel 240 mg/m 2 intravenously, D2; apatinib 500 mg orally, once a day, D1-D21; S-1 40-60 mg twice a day, D1-D14). Patients who have been evaluated by multidisciplinary team to be eligible for radical surgery should stop treatment for at least 2 weeks. Patients were discontinued from the study when disease progression or unbearable toxicity, or withdrew consent. We analyzed the conversion rate, objective response rate (ORR), disease control rate (DCR), overall survival (OS) and safety.Statistical data were show by numbers and persentages(%), and comparisons between subgroups were assessed by Fisher′s exact probability method. Patients survival was analyzed using Kaplan-Meier curves and compared between groups using Log-rank. Results:At the data of cutoff (December 15, 2021), the median follow-up duration was 19.6 months. Eight of 17 patients underwent gastrectomy, and all of them were R0 resection (47.1%, 95% CI: 0.262-0.690). ORR was 47.1%, DCR was 82.4%, the median overall survival was 23.63 months. Grade 3 and 4 adverse events occurred in 3 patients (17.6%), including neutropenia, thrombocytopenia, anemia and upper gastrointestinal hemorrhage. There were no serious treatment-related adverse events or treatment-related deaths. Conclusion:In this trial, the combination of camrelizumab, apatinib, nab-paclitaxel and S-1 as the conversion therapy showed significant anti-tumor activity and manageable adverse events, providing a new option for locally unresectable advanced gastric cancer.

Objective:To retrospectively analyze the clinical characteristics of elderly patients who received colonoscopy and to explore the clinical value of regular colonoscopy for the elderly.Methods:This was a retrospective cohort study.A total of 1 154 patients aged 75 years and over undergone colonoscopy in Guangdong General Hospital from January 2015 to March 2018 were enrolled and divided into three groups, including 605 cases aged 75-79 years, 527 cases aged 80-89 years and 22 cases aged 90 years and over.Detection rates of colorectal lesions by colonoscopy were recorded.The clinical value of annual colonoscopy on the detection of colorectal lesions in elderly patients 75 years and older were analyzed to assess the necessity for regular monitoring.Results:Overall, 569 cases(49.3%)underwent colonoscopy with sedation and 585 cases(50.7%)underwent colonoscopy without sedation.The total positive detection rate was 83.4%(962/1 154), and the main lesions were polyps(858 cases, 74.4%), including 605(52.4%)cases of adenomas.Among the three groups, gastrointestinal bleeding was the main cause for colonoscopy in the group aged 90 years and over, while abdominal discomfort, elevated immunological tumor markers and history of non-colon cancer were the main reasons for colonoscopy in the group aged 75-79 years( P<0.05). A total of 153 cases underwent annual colonoscopy.The detection rate of polyps and adenomas decreased in the second exam, but still higher than 40.0%. Conclusions:Colonoscopy is a safe and effective method for the elderly population aged 75 years and over.Polyps and adenomas are the most common lesions.Recurrence of polyps after colorectal cancer and polypectomy is common and it is necessary to receive colonoscopy regularly.

Objective: To evaluate the efficacy of green surgery pathway on senile hip fractures. Methods: The green surgery pathway was implement in senile (≥75 years) hip fracture cases in our department since March 2016. A historically controlled trial study was designed: 97 senile hip fracture patients admitted between March 2016 and March 2017 were included in the intervention group and 78 senile hip fracture patients admitted between March 2015 and March 2016 were included in the control group. The patients’ general information were recorded, including gender, age, type of fracture, internal medical conditions, surgery method, the American Association of Anesthesiologists classification of physical status (ASA) classification, et al. The hip function was evaluated by the Harris score system at one week,6 months and one year after surgery. The waiting time for operation, operation time, length of hospital stay, complications during hospitalization and hip Harris score were compared between the two groups. Results: For the baseline data between the two groups in terms of gender, age, fracture type, surgery method, ASA classification, and combined underlying disease, the differences were not statistically significant. The waiting time for operation of the green surgery pathway group (36.3±7.8 h) was significantly shorter than that in the control group (46.9±11.4 h, t=6.995, P=0.000). The operation time of the green surgery pathway group was 45.4±17.5 min, and that of the control group was 43.8±20.8 min, the differences were not statistically significant. The length of hospital stay in the green surgery pathway group (6.8±2.4 d) was significantly shorter than that in the control group (9.5±2.8 d), the difference was statistically significant (t=6.866, P=0.000). In the green surgery pathway group, one patient developed acute myocardial infarction at 15 h after surgery and died of invalid rescue. In the control group, one patient developed acute cerebral hemorrhage 3 d after surgery and died of invalid rescue. The incidence of pulmonary infection, urinary tract infection, and acne in the green surgery pathway group were lower than that in the control group, the differences were statistically significant (χ^2PI=5.081, P_PI=0.024; χ^2UI=6.841, P_UI=0.009; χ^2acne=11.768, P_cne=0.001). For the incidence of acute myocardial infarction, acute cerebrovascular accident, pulmonary embolism and deep vein thrombosis between the two groups, the differences were not statistically significant. The Harris score of hip in the green surgery pathway was higher than that in the control group (72.6±13.1 points vs 62.2±15.4 points, t=4.826, P=0.000) one week after the surgery, the difference was statistically significant. While the score was slightly higher than that of the control group in the half year (93.8±16.8 vs 90.5±14.7) and one year (94.1±18.3 vs 92.4±15.9) after surgery, but the differences were not statistically significant. The mortality rate of the green surgery pathway was slightly lower than that of the control group within one year after surgery (6.19% vs 8.97%), but the difference was not statistically significant. Conclusion The implementation of green surgery pathway can reduce the occurrence of complications in bed, promote the early hip rehabilitation, effectively shorten the hospitalization time. It is worth further promotion because of its social benefits and health economic benefits.

Objective To compare the safety and efficacy of the caudal block and Total Intravenous Anesthesia (TIVA) for transrectal ultrasound (TRUS) guided prostate biopsy.Methods 60 elderly patients with transrectal ultrasound guided transperineal prostate biopsy were randomized into Group A and Group B.Patients in Group A received ultrasound guided caudal block (0.33％ ropivacaine 15 ml) and patients in Group B received TIVA.In operation room (T1),immediately before operation (T2) and at the end of operation (T3),mean artery pressure (MAP),heart rate (HR),breathing rate (BR) and pulse oxygen saturation (SpO2) were recorded.The patients in two groups were rated the level of mini-mental state examination (MMES) at 2 h,8 h and 24 h after operation.Complications during the whole study period were also evaluated.Results The values of MAP,HR and BR of T1 in group B were significantly lower than those at T2 (P＜0.05),and were lower than those in the group A (P ＜0.05).The MMSE value in group A [2 h (25.66 ± 1.71) and 8 h (26.13 ± 1.52)] was significantly higher than that in group B [2 h (27.96 ± 1.71) and 8 h (29.01 ± 0.77)] at after operation (P ＜ 0.05).The rate of usage of ephedrine (13％) and assisted ventilation (20％) in group B was higher.No significant differences were detected in side effects between the two groups.Conclusions Caudal block provides better anesthesia than TIVA for TRUS guided prostate biopsy without an increase of side effects,and it may be safely used during ambulatory surgery.
