【Objective】 To investigate the physical and neuropsychological development of the offspring born to mothers with gestational diabetes mellitus (GDM) at 2 years of age, and to provide evidence to enhance the physical and neuropsychological development of GDM offspring. 【Methods】 A retrospective analysis was conducted on neonates born in the Department of Obstetrics at Qinzhou Maternal and Child Health Hospital from January 2018 to December 2018 and regularly followed at the outpatient service. The neonates were categorized into two groups based on whether their mothers were diagnosed with GDM during pregnancy: the GDM group (n=243) and the control group (n=362). The general clinical data, follow-up information on physical development and neuropsychological development at 1 year and 2 years of age for all children were collected. Their height, head circumference, body weight, BMI, and Gesell developmental quotients (DQs) at 1 year and 2 years of age for both groups were analyzed. 【Results】 1) There were no significant differences in height, head circumference, body weight, and body mass index (BMI) between the two groups at 1 year and 2 years of age during the follow-up period (P>0.05). 2) At 1 year of age, the GDM group exhibited higher rates of abnormal language development (8.6% vs. 3.3%, χ²=7.854), adaptive behavior(11.4% vs. 5.0%,χ²=8.605), and personal social behavior(8.2% vs. 3.0%, χ²=8.062) compared to the control group (P<0.05), and lower DQs for these Gesell subscales (language development 87.6±7.7 vs. 89.4±9.2, t=2.591; adaptive behavior: 88.4±7.8 vs. 90.5±8.9, t=2.957; personal social behavior: 89.1±7.0 vs. 91.2±7.5, t=3.495, P<0.05). 3) At 2 year of age, the GDM group also showed higher rates of adaptive behavior (8.2% vs. 4.1%, χ²=3.927) and personal social behavior (7.3% vs. 3.0%, χ²=4.093) compared to the control group (P<0.05), and lower DQs for these Gesell subscales (adaptive behavior: 89.5±6.5 vs. 91.9±6.9, t=3.878; personal social behavior: 89.9±7.1 vs. 92.1±6.9, t=3.311, P<0.05). 【Conclusions】 The development of adaptive behavior and personal social behavior in offspring born to mothers with GDM remains delayed. Follow-up for GDM offspring should prioritize achieving a balanced development of adaptive behavior and personal social behavior.

Objective:To investigate the protective effect of quercetin (QR) on acute liver injury induced by diquat (DQ) poisoning in mice and its mechanism.Methods:Eighty healthy male C57BL/6 mice with SPF grade were randomly divided into control group, DQ model group, QR treatment group, and QR control group, with 20 mice in each group. The DQ poisoning model was established by a one-time intraperitoneal injection of DQ solution (40 mg/kg); the control and QR control groups received equivalent amounts of distilled water through intraperitoneal injection. Four hours after modeling, the QR treatment group and the QR control group received 0.5 mL QR solution (50 mg/kg) through gavage. Meanwhile, an equivalent amount of distilled water was given orally to the control group and the DQ model group. The treatments above were administered once daily for seven consecutive days. Afterwards, the mice were anesthetized, blood and liver tissues were collected for following tests: changes in the structure of mice liver tissue were observed using transmission electron microscopy; the levels of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected using enzyme linked immunosorbent assay (ELISA); the levels of glutathione (GSH), superoxide dismutase (SOD), and malondialdehyde (MDA) in liver tissues were measured using the water-soluble tetrazolium-1 (WST-1) method, the thiobarbituric acid (TBA) method, and enzymatic methods, respectively; the protein expressions of nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), Kelch-like ECH-associated protein 1 (Keap1), and activated caspase-9 in liver tissues were detected using Western blotting.Results:Severe mitochondrial damage was observed in the liver tissues of mice in the DQ model group using transmission electron microscopy, yet mitochondrial damage in the QR treatment group showed significant alleviation. Compared to the control group, the DQ model group had significantly increased levels of MDA in liver tissue, serum AST, and ALT, yet had significantly decreased levels of GSH and SOD in liver tissue. In comparison to the DQ model group, the QR treatment group exhibited significant reductions in serum levels of ALT and AST, as well as MDA levels in liver tissue [ALT (U/L): 52.60±6.44 vs. 95.70±8.00, AST (U/L): 170.45±19.33 vs. 251.10±13.09, MDA (nmol/mg): 12.63±3.41 vs. 18.04±3.72], and notable increases in GSH and SOD levels in liver tissue [GSH (μmol/mg): 39.49±6.33 vs. 20.26±3.96, SOD (U/mg): 121.40±11.75 vs. 81.67±10.01], all the differences were statistically significant (all P < 0.01). Western blotting results indicated that the protein expressions of Nrf2 and HO-1 in liver tissues of the DQ model group were significantly decreased compared to the control group. On the other hand, the protein expressions of Keap1 and activated caspase-9 were conspicuously higher when compared to the control group. In comparison to the DQ model group, the QR treatment group showed a significant increase in the protein expressions of Nrf2 and HO-1 in liver tissues (Nrf2/β-actin: 1.17±0.08 vs. 0.92±0.45, HO-1/β-actin: 1.53±0.17 vs. 0.84±0.09). By contrast, there was a notable decrease in the protein expressions of Keap1 and activated caspase-9 (Keap1/β-actin: 0.48±0.06 vs. 1.22±0.09, activated caspase-9/β-actin: 1.17±0.12 vs. 1.59±0.30), the differences were statistically significant (all P < 0.01). Conclusion:QR may reduce acute liver injury induced by DQ poisoning in mice via activating Keap1/Nrf2 signaling pathway.

Objective:To investigate the potential mechanism of miR-1298-5p in non-small cell lung cancer(NSCLC)to regu-late the MSH2 gene and its effect on the biological behavior of tumor cells and the tumor immune microenvironment.Methods:Bioin-formatics was used to identify the key genes and miRNA involved in NSCLC.Cell proliferation was detected by CCK-8 assay,and cell invasion and migration were detected by Transwell assay.Levels of inflammatory factors were detected by ELISA assay.Western blot was used to measure the expression of MSH2 in cells,and fluorescence quantitative polymerase chain reaction(RT-qPCR)was used to detect the expressions of miR-1298-5p and MSH2 gene in NSCLC cells.Dual luciferase reporter gene assay was performed to verify the targeting relationship between miR-1298-5p and MSH2.Spearman correlation analysis was performed to correlate miR-1298-5p with immune cells and immune factors in the tumor immune microenvironment.Results:The level of miR-1298-5p was down-regulated in NSCLC cells compared with normal lung tissue cells.miR-1298-5p overexpression inhibited the proliferation,migration and inva-sion of NSCLC cells.MSH2 was confirmed to be a target gene of miR-1298-5p using luciferase reporter gene assay.Furthermore,down-regulation of miR-1298-5p in NSCLC cells could be reversed by silencing MSH2.miR-1298-5p expression levels were negatively corre-lated with the levels of Treg,IL-10,and TGF-β,and positively correlated with the levels of CD3+T,CD4+T,CD8+T,NK cells,IL-2,and IFN-γ.Conclusion:miR-1298-5p negatively regulates MSH2 to inhibit the proliferation,invasion and migration of NSCLC cells and improve the tumor immune microenvironment.

Objective To explore the expression and diagnostic value of circulating microRNA(miR)-126-3p in non-small cell lung cancer(NSCLC).Methods Multi-centred miR chips and sequencing data were col-lected to investigate the differential expression of circulating miR-126-3p in NSCLC.In order to evaluate the comprehensive expression level of circulating miR-126-3p in the cycle,the standardized mean difference(SMD)and summary receiver operating characteristic(sROC)curve were calculated,and the area under curve(AUC)of sROC curve was analyzed.Sensitivity,specificity,positive negative likelihood ratio were ex-plored,and the expression of circulating miR-126-3p was further comprehensively analyzed in combination with tissue.By using miRDB,starBase v2.0,and TargetScan 7.1,combined with up-regulated differentially expressed genes in NSCLC,potential target genes of circulating miR-126-3p were screened using complemen-tary sequence method.Results Based on six circulating miR datasets,the expression level of circulating miR-126-3p was higher than that of the control group,and the difference was statistically significant(P＜0.05).The receiver operating characteristic curves showed that circulating miR-126-3p had strong diagnostic efficacy(AUC＞0.5),and the comprehensive expression of circulating miR-126-3p was lower in 199 cases of NSCLC group than in the control group(SMD=-1.46).The sROC curve showed that circulating miR-126-3p distin-guished the NSCLC group from the control group with high accuracy(AUC=0.91),Egger's test showed no publication bias(P＞0.05),with sensitivity and specificity 0.80,and positive likelihood ratio and negative likelihood ratio were 5.37 and 0.18,respectively.In addition,a comprehensive analysis of the circulation and tissue of 1 320 NSCLC samples from 26 datasets showed that circulating miR-126-3p expression was lower in NSCLC group than in the control group(SMD=-2.07).The sROC curve showed that low-expression circu-lating miR-126-3p had high accuracy in distinguishing between the NSCLC group and the control group(AUC=0.97).In addition,potential target genes ADAM9 and SLC7A5 were screened for circulating miR-126-3p,and their expression in NSCLC group was higher than that in the control group.Conclusion Low ex-pression of circulating miR-126-3p in the circulation may be an important biomarker for high-precision screen-ing of NSCLC.

Objective:To analyze the efficacy, safety and learning curve of Thulium laser enucleation of the prostate by laser controller(LC-THuLEP) anchored at six o'clock position of the bladder neck in the treatment of benign prostatic hyperplasia(BPH) with large gland.Methods:The clinical data of the 1st to 45th BPH cases with large gland(prostate volume> 80 ml) treated by a doctor with LC-THuLEP anchored at six o'clock position of bladder neck in Shanghai East Hospital from January to October 2022 were retrospectively analyzed. The patients were divided into groups A, B and C according to the order of operation time, with 15 cases in each group. There were no significant differences among the three groups( P>0.05) in age[(71.8±9.4)years old vs. (73.5±8.2) years old vs.(71.4±5.5)years old], prostate volume[88.3(84.8, 100.6)ml vs.91.5(86.1, 118.4)ml vs. 94.5(84.7, 101.8)ml], prostate specific antigen(PSA)[4.8(2.9, 8.5)ng/ml vs. 7.2(3.2, 11.2)ng/ml vs. 7.8(4.5, 12.7)ng/ml], postvoid residual volume[44.0(34.0, 67.0)ml vs. 60.0(40.0, 76.0)ml vs. 39.0(0, 59.0)ml], maximum urine flow rate(Q max)[8.4(7.6, 11.1)ml/s vs. 8.6(6.5, 10.6)ml/s vs. 10.4(7.8, 13.2)ml/s], international prostate symptom score(IPSS)[20(18, 21) vs. 20(20, 22) vs. 20(20, 25)]and quality of life(QOL)[4(4, 5) vs. 4(4, 4) vs. 4(3, 5)].The doctor had more than 100 cases of TURP surgery experience. LC-THuLEP anchored at six o'clock position of bladder neck was described as follows. The bladder neck at six o'clock position is reserved 0.5-1.0 cm as an "anchor" to fix the prostatic bladder neck when the gland was pushed directly by the laser controller, preventing the detached prostate gland from turning. Finally the bladder neck was cut off at six o'clock position, and the prostate was en-bloc removed. The effect of surgery and postoperative complications were compared. The enucleation efficiency was equal to the weight of prostate tissue removed divided by the time of enucleation. Results:The differences among the three groups in operation time [100.0(90.0, 110.0)min vs. 80.0(70.0, 90.0)min vs. 75.0(70.0, 90.0)min], enucleation time[89.0(72.0, 97.0)min vs. 67.0(64.0, 77.0)min vs. 64.0(60.0, 77.0)min] and the efficiency of enucleation [0.65(0.62, 0.68)g/min vs. 0.84(0.83, 0.94)g/min vs. 0.93(0.82, 1.00)g/min] were statistically significant( P<0.05). The operation time and enucleation time in groups B and C were significantly lower than those in group A, and the enucleation efficiency was significantly higher than that in group A( P<0.05), while there was no significant difference between group B and C. However, the difference of three groups in hemoglobin decrease [8.0(5.0, 11.0)g/L vs. 7.0(2.0, 10.0)g/L vs. 11.0(4.0, 16.0)g/L] and catheter indwelling duration[4.0(2.0, 6.0)d vs. 6.0(3.0, 7.0)d vs. 4.0(3.0, 6.0)d] were not statistically different( P>0.05). All patients were followed up for 6 months after surgery. In three groups, postoperative Q max were 23.2(21.0, 25.1)ml/s, 22.7(21.1, 26.1)ml/s and 22.9(21.5, 25.7)ml/s, IPSS were 6(5, 8), 7(6, 8) and 7(7, 8), QOL were 2(1, 2), 2(1, 2) and 2(1, 2), postvoid residual volume were 20.0(10.0, 25.0)ml, 22.0(15.0, 25.0)ml and 5.0(0, 25.0)ml, respectively, which were all significantly different from that of pre-operation( P<0.05).However, there were no statistically significant differences in the postoperative indicators among the three groups ( P>0.05). No statistical difference was found in postoperative complications among the three groups[26.7%(4/15) vs. 20.0%(3/15) vs. 20.0%(3/15), P>0.05]. Conclusions:LC-THuLEP anchored at six o'clock position of bladder neck was an effective operation in the treatment of BPH with large gland, and the learning curve could be reached after 15 cases.

Objective:To investigate the efficacy of Peritoneal interposition flap (PIF) technique in preventing postoperative pelvic lymphocele formation during laparoscopic radical prostatectomy with extended pelvic lymph node dissection (LRP+ ePLND).Methods:A retrospective analysis was conducted on clinical data of 113 patients with locally high-risk or locally advanced prostate cancer who underwent LRP+ ePLND at Shanghai East Hospital, from January 2020 to November 2023. Among them, 27 patients received PIF technique and 86 received traditional LRP+ ePLND. ePLND was carried out as the clearance of external iliac vessels, medial side of the internal iliac artery, and pararectal lymph nodes. The PIF technique was the suturing the peritoneal flap after freeing the bladder to the lateral side of the bladder, pulling the peritoneal edge that follows the bladder's free edge posteriorly to the pubis, curling it onto the lateral surface of the bladder. This could expose the lymph node clearance bed, establishing a pathway from the lymph node clearance bed to the abdominal cavity space, allowing exuded lymphatic fluid to flow into the abdominal cavity for absorption by the peritoneum. There were no statistically significant differences in age [(68.37±6.92)years vs.(70.47±5.72)years], body mass index [(25.47±2.49)kg/m 2vs.(24.46±2.80)kg/m 2], and preoperative PSA [(23.28±13.94)ng/ml vs.(24.81±13.99)ng/ml] between the PIF group and the control group ( P>0.05). Biopsy Gleason score in PIF group: 6 in 2 cases, 7 in 9 cases, 8 in 9 cases, 9-10 in 2 cases. Biopsy Gleason score in control group: 6 in 4 cases, 7 in 35 cases, 8 in 27 cases, 9-10 in 20 cases. Clinic stage in PIF group: T 2 in 18 cases, T 3 in 6 cases, T 4 in 3 cases. Clinic stage in control group: T 2 in 51cases, T 3 in 27 cases, T 4 in 8 cases. The preoperative Gleason scores and TNM staging comparisons between the PIF group and the control group showed no statistically significant differences ( P>0.05). Surgical duration, intraoperative blood loss, lymph node positivity rate, incidence of postoperative lymphocele, and recovery of urinary control were compared between the two groups. Results:All surgeries were completed successfully without intraoperative complications in both groups. There were no statistically significant differences between the PIF group and the control group in terms of surgical duration [(202.96±24.15)min vs.(201.1±29.85)min], intraoperative blood loss [(85.56±32.27)ml vs.(90.7±49.25)ml], and lymph node positivity rate [(4 in PIF group, 14.8%)vs.(25 in control group, 29.1%)]( P>0.05). Urinary catheters were retained for 10-14 days postoperatively. Following catheter removal, there were no statistically significant differences in urinary control rates at 1 month [51.85%(14/27)vs. 48.83%(42/86)]and 2 months[74.07%(20/27) vs. 72.09%(62/86)] between the PIF group and the control group ( P>0.05). At the 2 to 6-month follow-up CT scan, none of the 27 patients in the PIF group developed pelvic lymphocele, whereas 9 patients in the control group did (6 cases bilateral, 3 cases unilateral), showing a statistically significant difference between the two groups ( P=0.002). Postoperatively, 3 patients in the control group experienced symptoms, with 1 case of lymphocele infection causing fever 1 month after surgery. Lymphocysts were found in 2 patients with ipsilateral lower extremity swelling 2 weeks after surgery. Conclusions:The application of PIF technique during laparoscopic radical prostatectomy with extended pelvic lymph node dissection via the abdominal approach could be safe and feasible. It may prevent postoperative pelvic lymphocele formation.

Objective:To analyze the clinical efficacy and safety of camrelizumab combined with apatinib as a second-line therapy for unresectable hepatocellular carcinoma (HCC).Methods:Ninety-four cases with mid-and advanced-stage HCC who received camrelizumab combined with apatinib as second-line treatment were enrolled. Routine blood test, blood biochemical indexes, tumor stage, tumor imaging characteristics, previous treatment strategies and other clinical data before treatment were documented. Imaging examination follow-up results and adverse reactions during treatment were followed up until the end of follow-up or loss of follow-up or death. Kaplan-Meier method was used to analyze the clinical efficacy.Results:As of the last follow-up, 94 cases with mid-and advanced-stage HCC had received camrelizumab combined with apatinib as second-line treatment. Among them, 15 cases were lost to follow-up, 31 cases died, and 48 cases survived. The overall remission rate was 31.9%. The overall disease control rate was 71.3%. The median time to disease-free progression was 6.6 months. The median time to disease progression was not yet available. The 1-year cumulative survival rate was 62.3%. Grade 3 and above adverse reactions mainly included were thrombocytopenia (7.4%), abdominal pain (4.3%), active hepatitis (4.3%), leukopenia (4.3%), diarrhea (3.2%), hand-foot syndrome (3.2%). All adverse reactions were effectively controlled.Conclusion:Camrelizumab combined with apatinib can effectively prolong the survival period of patients with mid-and advanced-stage HCC, and it is well tolerated.

Objective:To investigate the correlation between subclinical hypothyroidism(SCH)and the degree of coronary artery stenosis in patients with coronary heart disease.Methods:From March 2018 to September 2019, 138 patients undergoing coronary angiography in our hospital were randomly selected and their serum thyroxine(FT4)and high-sensitivity thyroid stimulating hormone(sTSH)levels were measured.Based on the levels of FT4 and sTSH, patients were divided into the SCH group and the normal group.Combined with coronary angiography results, the correlation between the SCH and the number of coronary lesions were analyzed.Results:Patients in the SCH group were associated with significantly higher levels of cholesterol(TC)[(5.83±1.27)mmol/L vs.(5.02±1.22)mmol/L, t=3.746, P=0.000], triglyceride(TG)[(3.29±1.74)mmol/L vs.(2.17±1.68)mmol/L, t=3.769, P=0.000], low-density lipoprotein cholesterol(LDL-C)[(3.81±1.02)mmol/L vs.(3.24±1.08)mmol/L, t=3.092, P=0.001], and high-density lipoprotein cholesterol(HDL-C)[(1.13±0.27)mmol/L vs.(1.02±0.25)mmol/L, t=2.4459, P=0.008]than those in the normal group.There were significant differences in sTSH levels between patients with multivessel, double vessel or single vessel disease when grouped by the number of coronary lesions, and between those with severe, moderate or mild coronary artery stenosis when grouped by disease severity(all P<0.05). Multiple regression analysis showed that SCH, TC, and LDL-C were factors affecting the number of coronary lesions( P<0.05). Conclusions:SCH is an important factor that causes the occurrence and progression of coronary artery stenosis in patients with coronary heart disease, mainly by affecting lipid metabolism.

OBJECTIVE: To investigate the prognosis of patients with vulnerable plaque indicated by coronary CT angiography (CCTA). METHODS: Totally 1963 patients underwent CCTA from February 2nd 2015 to September 13th 2015, and 2728 coronary borderline lesions (stenosis of 50%-70%) were detected. Among them 804 patients had vulnerable plaques and 1159 patients had stable plaques. The primary endpoint was major cardiac adverse events (MACE), including cardiac death, acute myocardial infarction and target lesion revascularization. RESULTS: Patients were followed up for a mean follow-up of 27.4±2.3 months. The incidence of MACE in the vulnerable plaque group was significantly higher than that in the stable plaque group (10.8%vs 2.3%, < 0.01). After adjusting for age, gender, smoking, hypertension, diabetes, hyperlipidemia, the MACE hazard ratio () in the vulnerable plaque group was 5.022 (95% :3.254-7.751, < 0.01).Subgroup analysis showed that in the vulnerable plaque group, the incidence of MACE in patients taking antiplatelet and statin ≤3 months and those taking antiplatelet and statin > 3 months was 17.0%and 5.8%, respectively (=3.149, 95% :1.987-4.992, < 0.01); but the difference did not seen in stable plaque group (=1.721, 95% :0.798-3.712, >0.05). CONCLUSIONS This study confirmed the risk of MACE in patients with vulnerable plaque detected by CCTA and the drug treatment may reduce the risk for patients with vulnerable plaque.

Objective To investigate the feasibility and practical value of the integration of humanistic concern into clinical problem-based learning ( PBL ) teaching . Methods A total of 112 undergraduate medical interns in Department of Colorectal Surgery were enrolled and randomly divided into experimental group receiving PBL teaching integrated with humanistic concern and control group receiving PBL teaching alone. Theoretical examination, operation examination, and patient satisfaction survey were performed after practice training to evaluate the teaching effect of the two groups . GraphPad Prism 6 software was used for statistical analysis of data, and the t-test was used for comparison of continuous data between the two groups. Results Compared with the control group, the experimental group had significantly higher scores of medical history collection (22.57±2.63 vs 20.87±3.08, t=3.124, P=0.002) and operation skills (31.42±2.89 vs 29.87±4.72, t=2.107, P=0.037), but there were no significant differences between the two groups in the scores of theoretical examination (90.60±3.19 vs 90.52±3.38, t=0.129, P=0.898) and medical record writing (20.78±2.79 vs 20.65±3.51, t=0.215, P=0.830). Compared with the control group, the experimental group had a significantly higher degree of patient satisfaction with service attitude (3.94±1.07 vs 3.22±1.09, t=3.256, P=0.002), trust (3.85±1.16 vs 3.22±1.05, t=2.759, P=0.007), and communication skills (3.92±1.03 vs 3.16±1.03, t=3.652, P=0.000), but there were no significant differences between the two groups in the scores of operating skills (3.60±1.09 vs 3.67±1.10, t=0.281, P=0.779) and arrangement of medical procedures (2.74 ±1.10 vs 3.02 ±1.02, t=1.312, P=0.193). Conclusion The integration of humanistic concern into PBL teaching of anorectal surgery can improve students' clinical operation ability and degree of patient satisfaction.
