OBJECTIVE To investigate the correlation between serum levels of asprosin and adropin in elderly patients with obstructive sleep apnea syndrome(OSAS)and the disease severity.METHODS From August 2021 to August 2023,131 elderly OSAS patients admitted to Ezhou Central Hospital were collected as observation subjects(OSAS group),according to the sleep apnea hypopnea index(AHI),there were 40 cases in the mild group,52 cases in the moderate group,and 39 cases in the severe group,meantime,124 healthy individuals who came to health clinic of our hospital for physical examination were collected as the control group.Enzyme-linked immunosorbent assay(ELISA)was applied to determine the levels of asprosin and apropin in the serum of OSAS patients;Pearson method was applied to analyze the correlation between serum asprosin,apropin levels and AHI,ODI,and LSaO2.ROC curve was used to analyze the diagnostic value of serum asprosin and adropin levels in OSAS and the severity of OSAS patients.RESULTS Compared with the control group,the asprosin level in the OSAS group was obviously increased,while the adropin level was obviously reduced(P<0.05).There was no statistically obvious difference in gender,age,coronary heart disease,hypertension,TC,TG,HDL-C,LDL-C among the mild,moderate,and severe groups(P>0.05);compared with the mild group,the levels of BMI,AHI,ODI,and asprosin in the moderate and severe groups were obviously increased,while the levels of LSaO2 and apropin were obviously reduced(P<0.05);compared with the moderate group,the levels of BMI,AHI,ODI,and asprosin in the severe group were obviously increased,while the levels of LSaO2 and apropin were obviously reduced(P<0.05).The serum asprosin level in OSAS patients was positively correlated with AHI and ODI,and negatively correlated with LSaO2(P<0.05);the level of apropin was negatively correlated with AHI and ODI,and positively correlated with LSaO2(P<0.05).The AUC of serum asprosin,apropin levels,and their combination in diagnosing moderate and severe OSAS was 0.832,0.882,and 0.942,respectively,the combined diagnostic value of the two was superior to that of single diagnosis(Z=3.435,2.560,P=0.001,0.011).Serum asprosin,adropin levels and AUC of combined diagnosis of OSAS were 0.818,0.804 and 0.893,respectively.The value of combined diagnosis was better than that of single diagnosis(Z=3.886,4.126,P=0.000,0.000).CONCLUSION The serum level of asprosin is increased and the level of adropin is decreased in patients with OSAS,which is closely related to the severity of the disease,and may be used in the clinical diagnosis of OSAS and the evaluation of the severity of OSAS.

Objective:To investigate the application effects of a novel framework: the external septal retention bionic framework in East Asian rhinoplasty.Methods:A retrospective analysis was performed based on the clinical data of the patients who received treatments in Department of Plastic and Aesthetic ( Burn) Surgery, the Second Xiangya Hospital, Central South University from January 2022 to July 2023 using an external septal retention bionic framework with autologous costal cartilage rhinoplasty. The patients were all treated with a V-shaped incision at the nasal columella, which continued to both sides of the nose to form a bird-shaped incision. During the operation, the sixth or seventh costal cartilage was sculpted to form the nasal columella support grafts (sturt), external nasal septal graft, cap grafts, and shield grafts, in which the nasal column support graft and external nasal septal graft were implanted in a mortise-and-tenon joint structure to form a septum bionic retained external stent in order to lengthen the nasal columellar column and strengthen the septum. A capsular graft was used to shape the tip of the nose and the rectus abdominis fascia was covered to soften the tip of the nose, and the shield grafts were used to fill out the subnasal lobules. A bulb was sculpted, shaped and implanted in the dorsal space to elevate the nasal dorsum. To observe the postoperative results and complications, a postoperative satisfaction survey was completed using the rhinoplasty outcome evaluation (ROE) and the visual analogue scale (VAS) with regular follow-up. Comparison of preoperative and postoperative scale scores was performed using paired samples t-test. Nasal stent stability was assessed by measuring the patients’ preoperative and postoperative nasolabial angle and nasal tip protrusion. The comparison of preoperative and postoperative nasolabial angle was performed using the paired-sample t-test, and the comparison of nasal tip protrusion was performed using the Wilcoxon signed rank-sum test, P<0.05 considered a statistically significant difference. Results:A total of 33 patients were enrolled, including 4 males and 29 females, with average age of 23.8 years(15-42 years). The follow-up period is (14.52 ± 4.72) months (3 to 21 months). Thirty-three patients recovered well after surgery, and no short-term complications such as infection or bleeding occurred. The patients' nasal aesthetic problems such as saddle nose, deviated nasal columella, bilateral asymmetry of the nose, bilateral nasal base depression, and rounded shield of the nasal tip were improved after surgery. Satisfaction survey results: ROE and VAS scores were significantly higher than those before surgery, which were [(17.92±2.56) vs.(12.78±3.14)] and [(8.08±1.66)vs(5.15±1.99)], ( P<0.05), 87.9% (27/33)of the patients were satisfied with the aesthetic and functional outcomes of the nose. Comparisons of nasolabial angle [(87.28±2.58)° vs. (97.64±1.95)°] and tip protrusion [1.88 (1.78, 1.95) cm vs. 2.16(2.01, 2.32) cm] measurements between preoperative and postoperative period of the 33 patients, the differences were statistically significant ( P<0.05). Conclusion:Rhinoplasty for East Asians employs an external septal retention bionic framework to retain the nasal septum. This technique can avoid septal cartilage resorption caused by compression of grafts transplanted in the future, and cause less damage to the anatomy and physiology of the nose. The framework is relatively easy to construct, with a stable and strong stent, and good patient satisfaction. It can achieve a more desirable aesthetic effect of the nose.

Objective To compare the efficacy and safety of anlotinib(AL)and bevacizumab(BEVA)in the treatment of advanced lung adenocarcinoma(LUAD)with acquired resistance to epidermal growth factor receptor-tyrosine kinase inhibitors(EGFR-TKI).Methods The clinical data of patients with EGFR-TKI-resistant LUAD who were treated in the Department of Oncology of Yibin Third People's Hospital from January 2022 to January 2023 were retrospectively analyzed.According to the treatment plan,patients were divided into BEVA group and AL group.Both groups were treated with BEVA injection or AL capsule in combination with standard chemotherapy for a total of 4 cycles.The main outcome measures included changes in tumor marker levels[carcinoembryonic antigen(CEA),neuron-specific enolase(NSE),and vascular endothelial growth factor(VEGF)],recent clinical efficacy[overall response rate(ORR)and disease control rate(DCR)],progression-free survival(PFS),1-year survival rate,and drug-related adverse reactions.Results A total of 60 patients with EGFR-TKI-resistant LUAD were included in the study,including 32 patients in the BEVA group and 28 patients in the AL group.After four cycles of treatment,the levels of serum CEA,NSE,and VEGF in both groups significantly decreased,and AL group was lower than BEVA group(P<0.05).There were no significant statistical differences in the complete remission rate,partial remission rate,disease stability rate,and ORR between the two groups(P>0.05).Compared with the BEVA group,the AL group had a lower rate of disease progression(P<0.05)and a higher DCR(P<0.05).In addition,the median PFS in the BEVA group was significantly longer than that in the AL group(8.4 vs.7.2 months,P<0.05),while there was no significant difference in survival rate between the two groups(P>0.05).In terms of adverse reactions,patients in the AL group had a lower incidence of nausea and vomiting,but a higher incidence of bone marrow suppression,resulting in a lower overall adverse reaction grade.Conclusion Compared with the BEVA combination chemotherapy regimen,AL combination chemotherapy showed better efficacy and good safety in the treatment of EGFR-TKI-resistant advanced LUAD.

【Objective】 To explore the correlation between the severity of jaundice in ABO hemolytic disease of fetus and newborn (HDFN) and multiple indicators, in order to achieve accurate diagnosis, timely treatment, and prevent complications in ABO HDFN. 【Methods】 From March 2020 to February 2023, a total of 283 ABO HDFN in our hospital were classified into mild, moderate and severe groups based on total bilirubin levels. The differences in basic data, relevant laboratory indicators and the agglutination intensity of the three hemolysis tests were analyzed and compared. 【Results】 In the severe group, 75% (12/16) were male infants, which was significantly higher compared to 37.5% (57/152) in the moderate group (P<0.05). The values (mg/dL) of transcutaneous jaundice in the mild, moderate and severe groups were:forehead 9.88±1.93 vs 12.34±2.01 vs 15.56±2.69, face 10.25±2.27 vs 13.28±2.32 vs 15.99±2.86, chest 9.67±2.16 vs 12.51±2.11 vs 15.33±2.36, respectively. The values(µmol/L) of direct bilirubin (DBIL) and indirect bilirubin (IBIL) were 9.87±2.06 vs 11.90±2.59 vs 16.12±4.73, and 159.36±37.55 vs 252.98±30.52 vs 353.76±55.68, respectively, and the differences between the mild, moderate and severe groups were statistically significant (all P<0.05) . The creatine kinase (CK) values(unit/L) of mild, moderate and severe groups were 664.15±498.26 vs 500.51 ±451.63 vs 402.63±224.27, and the difference between the mild group and the other two groups was statistically significant (P<0.05) . There was no statistically significant difference in the agglutination intensity of the three hemolysis tests among HDFN with different severity of jaundice. 【Conclusion】 Clinicians can predict the severity of jaundice in light of gender, transcutaneous jaundice, DBIL, IBIL and CK of ABO HDFN, for further and graded treatment, so as to avoid the sequelae or even life-threatening consequences caused by ABO HDFN.

Ferroptosis, a new form of programmed cell death, could be regulated by lipid metabolism, amino acid metabolism, and iron metabolism. Ferroptosis is closely related to human physiological mechanisms and involved in the development and progression of multiple diseases. More and more researchers have found that ferroptosis also plays a vital role in pregnancy-related disorders such as preeclampsia, gestational diabetes, and miscarriage. However, the mechanisms have not yet been fully understood. This article reviews the progress in ferroptosis in pregnancy-related diseases to provide new directions for scientific research and clinical treatment.

The application of special laparoscopic techniques is focused on the GIST of cardia to preserve the function of the cardia.

Objective:To investigate the perioperative risk factors in contribution of hyperbilirubinemia following cardiopulmonary bypass(CPB) assisted cardiovascular surgery, of which cutoff values of key factors are defined.Methods:1 286 patients received cardiac surgery assisted by CPB from January 2017 to March 2019 were included in the study. The perioperative data and the peak serum total bilirubin at selected timepoints were recorded. Logistic regression of multi-factor analysis was used to define risk factors and then broken-line analysis was applied to predict the risky threshold. Results:312(24.26%)patients developed hyperbilirubinemia after surgery, with the in-hospital mortality rate up to 34.62%(108 cases). In those patients, valve surgery(45.51%, 142/312), great vessel open surgery(37.82%, 118/312) and heart transplantation(7.69%, 24/312) were mostly performed. The duration of postoperative ICU stay and the use of ventilation were 6 days and 68 hours, which were significantly higher than those in non-hyperbilirubinemia group( P<0.01). Multivariate logistic regression showed that the postoperative ventilation time>49 h, the cardiopulmonary bypass(CPB) time>181 min and the abnormal preoperative liver function, use of intra-aortic balloon pump and extracorporeal membrane oxygen, unplanned re-exploration for bleeding were the risk factors for postoperative hyperbilirubinemia( P<0.01). The cutoff duration of postoperative mechanical ventilation and CPB affecting the incidence of hyperbilirubinemia, ICU days and in-hospital mortality were 120.21 h and 143.26 min, 248.20 h and 239.51 min, 259.50 h and 190.60 min, respectively. Conclusion:Preoperative abnormal liver function, intraoperative CPB time, postoperative mechanical ventilation time, postoperative use of IABP or ECMO assistance, and unplanned secondary thoracotomy were high-risk factors for hyperbilirubinemia after CPB-assisted cardiovascular surgery.

Objective:To investigate the efficacy of the biopsy strategy combining 6-core systematic and 3-core MRI-targeted biopsy on prostate cancer (PCa) detection in biopsy-na?ve patients.Methods:The clinical data of 121 biopsy-na?ve patients who underwent transperineal prostate biopsy in West China Hospital of Sichuan University from July 2018 to January 2020 were retrospectively analyzed. The average age was (64.7±9.1) years old. Pre-biopsy prostate-specific antigen (PSA) was (12.4±7.5)ng/ml, f/t PSA was 0.13±0.05. Prostate volume was (43.1±26.1) ml and PASD was (0.35±0.27) ng/ml 2. The prostate-imaging and data system (PI-RADS) score of MRI before biopsy was reported to be 3 for 29 patients (24.0%), 4 for 54 patients (44.6%) and 5 for 38 patients (31.8%). All 121 patients underwent 12-core systematic biopsy combined with a 3-core or 5-core MRI-targeted biopsy, of which 61 patients underwent 3-core targeted biopsy and 60 underwent 5-core targeted biopsy. There was no significant difference in the pre-biopsy clinical data between the two groups ( P>0.05). A 6-core systematic biopsy was redefined as the results of 6 cores among the 12-core systematic biopsy. We compared the detection rates among the single 12-core systematic biopsy, 6-core systematic biopsy, MRI-targeted biopsy (3-core or 5-core), and different systematic biopsy combing with targeted biopsy for any PCa and clinically significant PCa, and we also analyzed the cumulative cancer detection rates for MRI-targeted biopsy of different cores. Results:Of the 121 patients in this study, the biopsy results were negative for 43 patients (35.5%) and positive for 78 (64.5%). The detection rate of clinically significant PCa was 55.4% (67/121). The detection rate of the 6-core systematic biopsy combined with MRI-targeted biopsy was 62.0% (75/121) for PCa and 55.4% (67/121) for clinically significant PCa, which was of no difference compared with that for the 12-core systematic biopsy combined with MRI-targeted biopsy ( P>0.05), but the 6-core systematic biopsy combined with MRI-targeted biopsy avoided the overdiagnosis of 3 patients with Gleason score 3+ 3. The detection rate of PCa for MRI-targeted biopsy was 57.9% (70/121), including 42.1% (51/121) for the first core, 55.4% (67/121) for the first two cores, and 57.9% (70/121) for the first three cores. Compared with the single-core targeted biopsy for suspicious lesions, the first 2-core targeted biopsy ( OR=1.7, 95% CI 1.0-2.8) and 3-core targeted biopsy ( OR=1.9, 95% CI 1.1-3.1) can significantly increase the detection rate of PCa, while the fourth or fifth core of targeted biopsy can not increase the detection rate additionally (60%, 36/60). Conclusion:For patients with suspected PCa, the prostate biopsy strategy combing 6-core systematic and 3-core MRI-targeted biopsy performs no inferior than the current 12-core systematic biopsy combined with MRI-targeted biopsy.

Objective:To compare the efficacy of haplotype hematopoietic stem cell transplantation (HIDT) and sibling matched hematopoietic stem cell transplantation (MSDT) in the treatment of complete remission (CR) acute T-lymphoblastic leukemia (T-ALL) .Methods:We retrospectively analyzed the clinical characteristics and outcomes of 98 patients who underwent HSCT in Hebei Yanda Ludaopei hospital with HID ( n=81) or ISD ( n=17) between May 2012 and May 2016. Results:The incidence of grades 2-4 and 3-4 acute-versus-host disease 100 days after HSCT were 51.9% (95% Confidence interval [ CI] 42.0%-64.0%) vs 29.4% (95% CI 14.1%-61.4%) ( P=0.072) and 9.8% (95% CI 5.1%-19.1%) vs 11.8% (95% CI 3.2%-43.3%) ( P=1.000) for HIDT and MSDT. The 100-day cumulative incidences of CMV and EBV viremia were 53.1% (95% CI 43.3%-65.2%) vs 29.4% (95% CI 14.1%-61.4%) ( P=0.115) and 35.8% (95% CI 26.8%-47.9%) vs11.8% (95% CI 3.2%-43.3%) ( P=0.048) . The 5-year overall survival, leukemia-free survival, cumulative incidences of relapse, and no-relapse mortality were 60.5% (95% CI 5.4%-49.0%) vs 68.8% (95% CI 11.8%-40.0%) ( P=0.315) , 58.0% (95% CI 5.5%-46.5%) vs 68.8% (95% CI 11.8%-40.0%) ( P=0.258) , 16.1% (95% CI 9.8%-26.4%) vs 11.8% (95% CI 3.2%-43.3%) ( P=0.643) , 25.9% (95% CI 17.9%-37.5%) vs 19.4% (95% CI 6.9%-54.4%) ( P=0.386) for HIDT and MSDT, respectively. Conclusion:HID could be a valid alternative donor for patients with T-ALL in CR lacking an identical donor.
