Objective:To analyse the 3D-Flair MRI manifestations of the inner ear, vestibular function status, and their correlation with hearing treatment outcomes in patients with severe sudden sensorineural hearing loss (SSNHL), and to explore potential prognostic indicators for sudden deafness.Methods:The clinical data of adult patients with unilateral profound sudden sensorineural hearing loss were retrospectively analyzed in Otorhinolaryngology Department of Shandong Provincial ENT Hospital from March 2018 to August 2020. Patients were categorized based on the results of their inner ear 3D-Flair MRI into two groups: the normal MRI group and the abnormal MRI group. The abnormal group was further divided into three subgroups: those with non-absorbed high signal in the inner ear, those with absorbed high signal, and those with destruction of the blood-labyrinth barrier. SPSS 26.0 statistical software was applied to analyze the differences in hearing efficacy, caloric tests, vestibular evoked myogenic potentials (VEMP), video head impulse tests (vHIT), and the incidence of dizziness/vertigo among various patient groups.Results:A total of 191 patients with complete data were collected (97 males and 94 females, aged from 13 to 69 years old). There were 50 cases in the normal inner ear 3D-Flair MRI group. A total of 141 cases were found in the group with abnormal 3D-Flair MRI, including 50 cases of high signal unabsorbed, 71 cases of absorption high signal and 20 cases of blood labyrinth barrier destruction. There were no significant differences in age, sex, lateral ratio of hearing loss and course of disease among four groups (all P>0.05).The significant efficiencies of hearing recovery, in the group with normal 3D-FLAIR MRI were better than those in the abnormal group ( P<0.05) after treatment. Among the four groups, there were significant differences in the apparent efficiency and total effective rate between the normal group and the inner ear high signal absorption group ( χ2=4.007, P=0.045; χ2=6.925, P=0.009). The abnormal rates of bithermal caloric test, vHIT results and dizziness/vertigo symptoms in the abnormal group were higher than those in the normal group ( P<0.05). There were significant differences in oVEMP abnormality rate, vHIT abnormality rate and incidence of dizziness/vertigo among the three groups with 3D-FLAIR MRI abnormality ( P<0.05). There were significant differences in caloric test, oVEMP, vHIT abnormality rate and incidence of dizziness/vertigo among the four groups ( P<0.05). The positive rates of caloric test, cVEMP test and vHIT test in patients with dizziness/vertigo were higher than those in patients without dizziness/vertigo ( P<0.05). The abnormal rates of posterior semicircular canal and horizontal semicircular canal in patients with dizziness/vertigo were significantly increased ( P<0.05) than patients without dizziness/vertigo. The recovery rate, effective rate and total effective rate of patients without dizziness/vertigo were significantly better than those with dizziness/vertigo ( P<0.05). Conclusions:The 3D-Flair MRI of the inner ear and vestibular function tests have reference value for the prognosis assessment of patients with severe sudden sensorineural hearing loss. Abnormal 3D-FLAIR MRI of the inner ear, especially absorption high signal, is associated with high incidence of vestibular dysfunction and dizziness/vertigo, with poor prognosis. Patients with severe sudden sensorineural hearing loss who have symptoms of dizziness/vertigo are more likely to exhibit abnormal results in vestibular function tests, with a higher susceptibility to involvement of the posterior and horizontal semicircular canals.

Objective:To explore the feasibility and effect of remote medical education model using online film reading training to improve the ability of ophthalmologists in the Xinjiang Uygur Autonomous Region (hereinafter referred to as "Xinjiang Region" ) in diagnosing fundus diseases.Methods:The three-level film reading training system of Xinjiang Production and Construction Corps system division hospital-Corps Hospital-Peking Union Medical College Hospital was established. From June 2022 to January 2023, 4 159 posterior color fundus images were continuously collected from Department of Ophthalmology of Xinjiang Corps Hospital and 4 divisional hospitals in the Corps medical system. Among them, hypertensive retinopathy, diabetic retinopathy, exudative age-related macular degeneration (AMD), atrophic AMD and retinal vein occlusion were 3 073, 651, 43, 186 and 206 cases, respectively. The images were divided into 3 rounds (first, second and last) according to the proportion of diseases. The doctors who participated in the training (hereinafter referred to as the "training") were 15 ophthalmologists from the Corps Hospital of Xinjiang Region and the division hospital of the Corps system. There were 7 male and 8 female. Age was (38.1±4.0) years. The titles of senior, deputy senior, intermediate and junior are 1, 6, 5 and 3 respectively; Bachelor's degree and master's degree are 13 and 2 respectively. The working time of fundus disease specialty was (9.6±3.3) years. The film reading system training was conducted before the first round of labeling, and after each round of film reading, the doctors of Peking Union Medical College Hospital gave feedback and explanation on the film reading results. The diagnostic consistency, sensitivity and specificity were compared by paired sample t test. Spearman or Pearson correlation analysis was conducted between the improvement of diagnostic level and professional title, education, age and working hours of ocular fundus disease. Results:All the participating doctors completed the first, second and last reading. After each round of film reading, the film reading summary was carried out for 2 hours. The average diagnostic agreement rates of participating physicians were 53.0%, 67.0% and 75.0%, respectively. The sensitivity and specificity were 0.38, 0.69, 054 and 0.66, 0.85, 0.96, respectively. There was significant difference between the first and last examination ( P<0.001). The sensitivity of the second reading was significantly higher than that of the first reading, and the sensitivity of the last reading was significantly lower than that of the second reading, with statistical significance ( P<0.05). The specificity of the second reading was significantly higher than that of the first reading, and the last reading was significantly higher than that of the second reading, with statistical significance ( P<0.05). There was no significant correlation ( P>0.05) between the improvement of diagnostic level of participating physicians and educational background ( Rho=0.07), professional title ( Rho=0.13), age ( r=0.20), and working time of ophthalmofundus disease specialty ( r=0.26). Conclusions:Relying on the three-level online telemedicine training, it can improve the ability of ophthalmologists in Xinjiang region to diagnose fundus diseases. The preliminary telemedicine education model has demonstrated potential for feasibility and effectiveness in remote areas with inadequate medical resources.

Objective To study the effect of interleukin-15(IL-15)on lipopolysaccharide(LPS)-induced apoptosis of septic cardiomyocytes and its related mechanism.Methods H9C2 cells were divided into control group(H9C2 cells in conventional culture),apoptosis group(LPS-induced myocardial cell injury model was established),and intervention group(10 ng/ml recombinant rat IL-15 was used in myocardial H9C2 cell injury model for 6 h).The effects of IL-15 on H9C2 cell proliferation and apoptosis were detected by methyl thiazolyl tetrazolium(MTT)assay and flow cytometry,the level of mitochondrial membrane potential was detected by staining of tetramethylrhodamine ethyl ester(TMRE).The sepsis mouse model was established by intraperitoneal injection of 10 mg/kg LPS,and 100 μl of normal saline containing 100 μg/ml IL-15 was injected intraperitoneally.HE staining was used to evaluate the pathological injury of mouse myocardium.The indexes of oxidative stress in mouse myocardium were detected by ELISA.The effects of IL-15 on the expression of heme oxygenase 1(HO-1)and NF-E2-related factor 2(Nrf2)mRNAs and proteins in myocardium of mouse sepsis model were detected by real-time fluorescence quantitative PCR and Western bloting.Results The apoptosis rate of H9C2 cells in the apoptosis group was significantly higher than that in the control group(47.9%±5.1%vs.2.1%±0.3%,P<0.05).The apoptosis rate of H9C2 cells in the intervention group was 20.7%±2.7%,which was significantly lower than that in the apoptosis group(P<0.05).LPS could significantly inhibit the proliferation of myocardial cells,while IL-15 could inhibit LPS-induced decrease in myocardial cell viability(P<0.05).The relative mitochondrial membrane potential of myocardial H9C2 cells in the apoptosis group was significantly lower than that in the control group(2.6±4.6 vs.7.4±5.2,P<0.05).The relative mitochondrial membrane potential of myocardial H9C2 cells in the intervention group was 4.2±4.9,which was significantly higher than that in the apoptosis group(P<0.05).LPS significantly enhanced the loss of mitochondrial membrane potential of myocardial H9C2 cells,and IL-15 intervention weakened the loss of mitochondrial membrane potential of H9C2 cells induced by LPS(P<0.05).HE staining revealed obvious myocardial tissue damage and inflammatory cell infiltration in mouse sepsis model.IL-15 ameliorated LPS-induced myocardial injury in mice.The expression levels of superoxide dismutase(SOD)and total antioxidant capacity(T-AOC)in myocardium of sepsis mice were significantly lower than those in normal mice,while the expression level of malondialdehyde(MDA)in sepsis mice was significantly higher than that in normal mice(P<0.05).After IL-15 intervention,the expression of SOD and T-AOC in myocardium of sepsis mice was increased,and the expression of MDA was decreased(P<0.05).The mRNA and protein expression levels of HO-1 and Nrf2 were low in myocardium of normal mice.The mRNA and protein expression levels of HO-1 and Nrf2 in myocardium of sepsis mice were significantly higher than those in normal mice(P<0.05).After IL-15 intervention,the mRNA and protein expression levels of HO-1 and Nrf2 were significantly increased in myocardium of sepsis mice(P<0.05).Conclusion IL-15 can protect cardiomyocyte apoptosis induced by sepsis and decrease myocardial injury in sepsis mice.The mechanism may be related to the activation of HO-1/Nrf2 signaling pathway and the inhibition of myocardial oxidative stress in septic mice.

Objective: To conduct a systematic review and meta-analysis of studies evaluating the oncological and fertility outcomes of early-stage endometrial cancer (EC) treated with the levonorgestrel-releasing intrauterine system (LIUS)-based regimens. Methods: The Meta-analyses Of Observational Studies in Epidemiology statement for meta-analyses was followed. Searches were conducted on MEDLINE, Embase, PubMed, Preprints, and the Cochrane Central Register of Controlled Trials from January 1990 to August 4, 2022. The Joanna Briggs Institute Critical Appraisal Checklist was used for quality assessment. The primary endpoint was the complete response (CR) rate and the secondary endpoints were relapse, pregnancy, and live birth rate. Results: A total of 25 studies (821 women) were included. The CR rate of LIUS-based regimens was 63.4% (95% confidence interval [CI]=52.3%–73.2%), with 29.6% (95% CI=23.3%–36.8%) of cases experiencing recurrence during follow-up. In sensitivity analyses, patients younger than 45 years of age with a body mass index <30 kg/m2 who were treated with LIUS-based regimens achieved a high CR rate of 84.6% (95% CI=80.3%–88.1%) over a median follow-up of more than 24 months. Overall pregnancy and live birth rates were 37.9% (95% CI=24.1%–53.9%) and 39.3% (95% CI=24.0%–57.0%), respectively. No statistical differences were apparent in CR or relapse rates among the LIUS+GnRH agonist, LIUS+oral progesterone, or hysteroscopic resection followed by LIUS subgroups. Conclusion LIUS-based therapies are viable for the conservative management of early-stage endometrioid EC on CR and fertility outcome.

Objective:To study clinical pathological characteristics, immunohistochemical, molecular genetical changes and prognosis in pediatric eosinophilic solid and cystic renal cell carcinoma (ESC RCC) with TSC2 gene mutations.Methods:The tissue samples were collected from two pediatric ESC RCC patients between 2017 and 2018. The tissues were subjected to histological examination and immunohistochemistry using EnVision system. The TFE3, TFEB gene rearrangements were tested using FISH and molecular genetic study. The paraffin sections were used for DNA extraction, PCR amplification and NGS sequencing.Results:The two patients with ESC RCC were both male, aged at 9 years and 8 months, and 13 years, respectively. The tumors were from the right kidney, 5 cm and 7 cm in size, respectively, with solid and cystic changes in cross section, and grey-reddish or grey-whitish fish meat appearance. Microscopic observation revealed the tumors had fibrous capsules, which were infiltrated by the tumor cells. The tumor cells were diffusely distributed, round-shaped, or polygon-shaped, and had voluminous cytoplasm, eosinophilic cytoplasm, various sizes of vacuoles and clear cell-like appearance. There were papillary structures in some areas, with visible fiber septa. The nuclei were round and vesicular, with multi-nucleated cells and megakaryocytes. The mitoses were not seen. A few cystic structures were visible in different sizes, and capsule walls were covered with a single layer of spike-like tumor cells. Thick-walled blood vessels were seen in the stroma, with focal lymphocytic infiltration, eosinophilic necrosis, calcifications and cholesterol crystals. Immunohistochemistry of the tumor cells was positive for PAX8 (diffuse), CK20 (focal), CKpan (focal), CK10 (1 focal, 1 diffuse), INI1, vimentin, CD68, and Ki-67 (5%~10%); the tumor cells were negative for HMB45, S-100, Melan A, p53, desmin, TFE3, CK7, CK19, EMA, CD56, CgA, Syn, CD30, CD117, WT1 and SMA. Molecular genetic study showed that TFE3 and TFEB gene rearrangements were not detected by FISH. NGS sequencing showed TSC2 p.Lys574Ter (0.198) was found in patient one and TSC2 p.Arg406Ter (0.355) in patient two.Conclusions:ESC RCC in children is a rare disease, and can be misdiagnosed easily. It has unique pathological characteristics, and immunohistochemical, molecular and genetic changes. The prognosis is relatively good.

Objective: To explore the clinical application value of enhanced recovery after surgery (ERAS) in the laparoscopic surgery for cholecystolithiasis comorbid with choledocholithiasis. Methods: The prospective study was conducted. The clinicopathological data of 52 patients with cholecystolithiasis comorbid with choledocholithiasis who were admitted to the Third Affiliated Hospital of Zunyi Medical University from September 2016 to September 2018 were collected. Patients were divided into 2 groups by random number table: patients in observation group received laparoscopic cholecystectomy + choledocholithotomy + choledochoscopic exploration + T-tube drainage (or primary suture of common bile duct) and perioperative management guided by the concept of enhanced recovery after surgery (ERAS), and patients in control group received traditional perioperative management. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) postoperative complications; (4) postoperative pain scores; (5) changes in hepatic function and blood routine during perioperative period. Follow-up using outpatient examination and telephone interview was performed to detect complications during the postoperative 6 months up to March 2019. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was analyzed using the paired t test or repeated ANOVA. Count data were described as absolute numbers and percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Results: Fifty-two patients were screened for eligibility, including 20 males and 32 females, aged 25-68 years, with an average age of 53 years. There were 30 patients in the observation group and 22 in the control group. (1) Surgical situations: the operation time and volume of intraoperative blood loss were (133±19)minutes and (47±21)mL in the observation group, and (136±22)minutes and (49±23)mL in the control group, respectively, showing no significant difference between the two groups (t=-0.386, -0.211, P>0.05). (2) Postoperative situations: time to out-of-bed activity, time to initial food intake, time to first anal flatus, duration of postoperative hospital stay, and hospital expenses were (18±4)hours, (19±5)hours, (28±2)hours, (4.0±1.0)days, and (1.82±0.22)×10⁴ yuan in the observation group, and (29±7)hours, (46±9)hours, (37±4)hours, (6.6±1.6)days, and (2.25±0.29)×10⁴ yuan in the control group, respectively, showing significant differences between the two groups (t=-7.054, -14.169, -9.426, -6.582, -5.809, P<0.05). (3) Postoperative complications: 1 of 30 patients in the observation group had postoperative biliary leakage, with a postoperative complication rate of 3.3%, and was cured after symptomatic support treatment. Six of 22 patients in the control group had postoperative complication, with a postoperative complication rate of 27.3%, including 2 of biliary leakage, 1 of hemorrhage, 1 of abdominal infection, 1 of pulmonary infection, 1 of urinary infection, and they were cured after symptomatic support treatment.

There was no significant difference in the changing trend between the two groups (F=0.058, 0.471, 3.021, 1.593, 2.172, P>0.05). Conclusion ERAS is safe and effective in the laparoscopic surgery for choledocholithiasis comorbid with cholecystolithiasis.

Objective To observe the effect of sitagliptin on carotid intima-media thickness (c-IMT) and serum hs-CRP and IL-6 levels in the patients with newly diagnosed type 2 diabetes mellitus. Methods 65 patients with newly diagnosed type 2 diabetes mellitus who were admitted to the outpatient clinic and were hospitalized in our hospital were selected. They were randomly divided into sitagliptin phosphate tablet group (experimental group) with 35 cases and metformin hydrochloride tablet group (control group) with 30 cases. All patients were given health education about diabetes, diet guidance and exercise. All patients were given drawing of venous blood at a fasting condition ≥10 h before treatment and 6 months after treatment to determine the following indicators: FPG, 2 hPG, hs-CRP, IL-6, TC, TG, HDL-c, LDL-c, HbA1 c, hs-CRP, IL-6, etc, and c-IMT was determined. Results There was no statistically significant difference in blood glucose, blood lipids, inflammation index and c-IMT between the two groups before treatment (P>0.05); after treatment, FPG, 2 hPG and HbA1 c were significantly lower than those before treatment in both groups, and the difference was statistically significant (P<0.01). There were statistically significant differences in FPG and HbA1 c between the two groups (P<0.01). There was no statistically significant difference in 2-hour postprandial blood glucose between groups (P>0.05). The c-IMT, hs-CRP and IL-6 levels in the experimental group after treatment were significantly lower than those before treatment, and the differences were statistically significant (P<0.05). There was no significant change in c-IMT in control group after treatment (P>0.05). hs-CRP and IL-6 had a decreasing trend compared with those before treatment, and the difference was not statistically significant (P>0.05). There were statistically significant differences in c-IMT, hs-CRP and IL-6 between the two groups after treatment (P<0.05). Spearman linear correlation analysis: c-IMT was positively correlated with hs-CRP levels and IL-6 (r=0.6585, P=0.000; r=0.571, P=0.000). There was no significant correlation between fasting blood glucose and glycosylated hemoglobin (P>0.05). Conclusion The DPP-4 inhibitor of sitagliptin has a clear hypoglycemic effect and can reduce c-IMT, hs-CRP and IL-6. The anti-inflammatory effects besides hypoglycemic effect may be involved in the reduction of atherosclerosis in the patients with diabetes mellitus.

Objective To investigate the effects of enteral nutritional emulsions on glucose and lipid metabolism in elderly patients with diabetes.
