ObjectiveTo observe the therapeutic effect of Qiwei Baizhusan（QWBZS） on diabetic encephalopathy（DE） rat model， and to explore the possible mechanism of QWBZS in the treatment of DE based on phosphatidylinositol 3-kinase（PI3K）/protein kinase B（Akt）/glycogen synthase kinase-3β（GSK-3β） signaling pathway. MethodForty-eight SPF male Wistar rats were randomly divided into blank group（8 rats） and high-fat diet group（40 rats）. After 12 weeks of feeding， rats in the high-fat diet group were intraperitoneally injected with 35 mg·kg^-1 of 1% streptozotocin（STZ） for 2 consecutive days to construct a DE model， and rats in the blank group were injected with the same amount of sodium citrate buffer. After successful modeling， according to blood glucose and body weight， model rats were randomly divided into model group， low， medium and high dose groups of QWBZS（3.15， 6.3， 12.6 g·kg^-1）， combined western medicine group（metformin+rosiglitazone， 0.21 g·kg^-1）， with 6 rats in each group. The administration group was given the corresponding dose of drug by gavage， and the blank group and the model group were given an equal volume of 0.9% sodium chloride solution by gavage， 1 time/day for 6 weeks. Morris water maze was used to detect the spatial memory ability of DE rats. Fasting insulin （FINS） level was detected by enzyme-linked immunosorbent assay（ELISA） and insulin resistance index（HOMA-IR） was calculated. Hematoxylin-eosin（HE） staining was used to observe the morphological changes of hippocampus in rats， ELISA was used to detect the indexes of oxidative stress in hippocampal tissues， real-time fluorescence quantitative polymerase chain reaction（Real-time PCR） was used to detect mRNA expression levels of PI3K， Akt， nuclear transcription factor-κB（NF-κB）， tumor necrosis factor-α（TNF-α） and interleukin-1β（IL-1β） in hippocampus， and Western blot was used to detect the protein expression of PI3K， Akt， phosphorylated（p）-Akt， GSK-3β and p-GSK-3β in hippocampus of rats. ResultCompared with the blank group， FINS and HOMA-IR values of the model group were significantly increased（P<0.01）， the path of finding the original position of the platform was significantly increased， and the escape latency was significantly prolonged（P<0.01）， the morphology of neuronal cells in hippocampal tissues was disrupted， the levels of reactive oxygen species（ROS） and malondialdehyde（MDA） in hippocampus of rats were increased， and the activity of superoxide dismutase（SOD） was decreased（P<0.05， P<0.01）， mRNA expression levels of PI3K and Akt were decreased（P<0.01）， mRNA expression levels of NF-κB， TNF-α and IL-1β were increased（P<0.05， P<0.01）， the protein expression levels of PI3K， p-Akt and p-GSK-3β were significantly decreased， and the protein expression of GSK-3β was significantly increased（P<0.01）. Compared with the model group， the FINS and HOMA-IR values of the medium dose group of QWBZS and the combined western medicine group were significantly decreased（P<0.01）， the path of finding the original position of the platform and the escape latency were significantly shortened（P<0.01）， the hippocampal tissue structure of rats was gradually recovered， and the morphological damage of nerve cells was significantly improved， the contents of ROS and MDA in hippocampus of rats decreased and the level of SOD increased（P<0.01）， the mRNA expression levels of PI3K and Akt were increased（P<0.01）， and the mRNA expression levels of NF-κB， TNF-α and IL-1β were decreased （P<0.05， P<0.01）， the protein expression levels of PI3K， p-Akt and p-GSK-3β were significantly increased（P<0.01）， and the expression of GSK-3β was significantly decreased（P<0.01）. ConclusionQWBZS can alleviate insulin resistance in DE rats， it may repair hippocampal neuronal damage and improve learning and cognitive ability of DE rats by activating PI3K/Akt/GSK-3β signaling pathway.

Fibroblast activation protein(FAP),a kind of transmembrane glycoprotein in the serine protease family,has an activity similar to dipeptidase and gelatinase.It is expressed in the stroma of a variety of human tumors and is involved in different signaling pathways.It promotes the proliferation,migration,and invasion of tumor cells through a variety of mechanisms.Therefore,it is closely related to the poor prognosis of many tumors.However,current studies have not systematically elucidated the expression of FAP in gastrointestinal malignancies,and research on its specific mechanism of action and role as a tumor biomarker and therapeutic target are still in the initial stage.In this article,the role and mechanism of FAP in the occurrence and progression of gastrointestinal malignancies are reviewed,in order to provide ideas for predicting the prognosis of gastrointestinal malignancies and selecting new therapeutic targets.

Objective To investigate the impact of the Shared Medical Appointment (SMA) model on blood glucose levels and self-management behaviors in patients with gestational diabetes mellitus (GDM). Methods A total of 87 pregnant women diagnosed with GDM at the Obstetrics and Gynecology and Endocrinology Outpatient Departments of the Affiliated Suqian Hospital of Xuzhou Medical University from October 2021 to October 2022 were enrolled and divided into treatment group (n=44) and control group (n=43). The treatment group received SMA-based GDM management, while the control group underwent routine outpatient follow-up. Baseline data, flash glucose monitoring (FGM)-related indicators before and after treatment, and self-management behavior scale scores were compared between the two groups. Results No statistically significant differences were observed between the two groups in age, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG), blood urea nitrogen (BUN), creatinine (Cr), uric acid (UA), triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and glycated hemoglobin (HbA1c) (P>0.05). After treatment, the time in range (TIR) of glucose was higher in the treatment group than that in the control group, while mean amplitude of glycemic excursions (MAGE), standard deviation of blood glucose (SDBG), coefficient of variation (CV), and mean blood glucose (MBG) were lower in the treatment group (P < 0.05). Within the treatment group, post-treatment TIR was higher, and MAGE, CV, SDBG, and MBG were lower than pre-treatment levels (P < 0.05). In the control group, post-treatment TIR was higher, and SDBG and MBG were lower than pre-treatment levels (P < 0.05). After treatment, the total score and scores for dietary management, exercise management, medication management, and blood glucose monitoring management in the self-management behavior scale were significantly higher in the treatment group than in the control group (P < 0.05). In the treatment group, post-treatment scores for all self-management behaviors were higher than pre-treatment levels, while post-treatment total scores and scores for medication management and blood glucose monitoring management in the control group were higher than pre-treatment levels (P < 0.05). Conclusion SMA management model can comprehensively improve blood glucose levels and enhance self-management behavior capabilities in GDM patients.

Objective:To study the incidence and risk factors of early hyperglycemia in extremely preterm infants (EPIs).Methods:From January 2018 to December 2021, EPIs with gestational age (GA) <28 w born in our hospital and admitted to the neonatal department were retrospectively studied. According to the occurrence of early hyperglycemia (within 1 w after birth), the infants were assigned into hyperglycemia group and non-hyperglycemia group. Univariate and logistic regression were used to analyze the risk factors of early hyperglycemia in EPIs.Results:A total of 218 cases of EPIs were enrolled, including 70 (32.1%) in the hyperglycemia group and 148 (67.9%) in the non-hyperglycemia group. The incidence of early hyperglycemia in EPIs with GA<25 w was 10/20 and 11/16 in EPIs with birth weight (BW) ≤700 g. The GA and BW of the hyperglycemia group were significantly lower than the non-hyperglycemia group ( P<0.05). More infants in the hyperglycemia group had 1-min and 5-min Apgar≤7 than the non-hyperglycemia group ( P<0.05). Logistic regression analysis showed that increased BW ( OR=0.995, 95% CI 0.993~0.997, P<0.05) was a protective factor for early hyperglycemia in EPIs, while male gender ( OR=2.512,95% CI 1.232~5.123, P<0.05), vasoactive drug use during the first week of life ( OR=2.687, 95% CI 1.126~6.414, P<0.05), maternal hypertension during pregnancy ( OR=14.735, 95% CI 1.578~137.585, P<0.05) were risk factors for early hyperglycaemia in EPIs. Conclusions:Early hyperglycemia are common among EPIs. Low BW, male gender, vasoactive drug use during the first week of life and maternal hypertension during pregnancy may increase the risk of early hyperglycemia.

Objective:To explore the efficacy of online problem management plus (PM+) intervention on the mental health among adults with anxiety.Methods:Ninety subjects with anxiety (Generalized Anxiety Disorder-7 (GAD-7) total score≥5) were enrolled and randomly allocated into either waiting group or online PM+group. Participants in the online PM+intervention group received online PM+intervention twice a week for 3 weeks, while participants in the waiting group received general psychological supports. Psychological evaluation was performed at the end of the 3-week treatment and at 6 months after treatment. Outcome measures included GAD-7, Patient Health Questionnaire -(PHQ-9), Patient Health Questionnaire-15 (PHQ-15), Perceived Stress Scale-14 (PSS-14), and Insomnia Severity Index (ISI). Two-factor repeated measure analysis of variance (ANOVA) was used to compare the scores of the two groups at baseline and after intervention. Single-factor repeated measure analysis of variance was used to compare the differences of scores at baseline,3-week post-intervention, and 6-month follow-up in the online PM+ group.Results:A total of 37 (37/45) pations in the online PM+intervention group and 30 (30/45) patients in the waiting group completed the psychological evaluation after intervention. After 3-week intervention, compared with baseline, no significant change was found in the scores of GAD-7 ( F=0.08, P=0.782), PHQ-9 ( F=0.33, P=0.570), PHQ-15 ( F=0.20, P=0.660), PSS-14 ( F=0.14, P=0.05) and ISI ( F=0.02, P=0.880) in the waiting group.

Objective:To study the predictive value of total serum bilirubin (TSB) and the ratio of bilirubin to albumin (B/A) in neonatal acute bilirubin encephalopathy (ABE).Methods:Neonates with extremely severe hyperbilirubinemia (TSB≥425 μmol/L) treated in the Nanjing Maternal and Child Health Hospital, Maternity and Child Health Care of Guangxi Zhuang Autonomous Region, Northwest Women and Children's Hospital, Yinchuan Maternal and Child Health Hospital and Liaocheng People's Hospital from March 2018 to August 2019 were selected as prospective subjects for this study. According to the score of brain injury induced by bilirubin, the subjects were divided into ABE group and non-ABE group, and the predictive value of TSB peak and B/A for neonatal ABE were analyzed.Results:A total of 194 infants with extremely severe hyperbilirubinemia were recruited in this study, including 20 in ABE group and 174 in non-ABE group. The peak value of bilirubin ranged from 427 to 979 μmol/L. The optimal critical values of TSB peak value and B/A for ABE prediction were 530 μmol/L and 9.48, respectively. The sensitivity and specificity of ABE prediction were 85.0% and 92.8% when combined with TSB peak and B/A values.Conclusions:TSB peak combined with B/A value can effectively identify neonatal ABE. When the TSB peak value was greater than 530 μmol/L and the B/A value was greater than 9.48, the neonates had a higher risk of neonatal ABE.

OBJECTIVETo study the risk factor of perioperative complication in gastric cancer patients with radical therapy and its influence on prognosis.

METHODSClinical, pathological and follow-up data of 1 148 gastric cancer patients undergoing radical gastrectomy at Tianjin Medical University Affiliated Tumor Hospital between January 2009 and August 2011 were retrospectively collected. Pearson 2 test and Logistic regression analysis were used to analyze the risk factor of perioperative complication. Cox regression analysis was used to evaluate the influence of perioperative complications on the prognosis in patients after radical gastrectomy. Kaplan-Meier survival curve was applied to calculate the survival.

RESULTSOf 1 148 patients, 851 were male, 297 were female, age ranged from 19 to 89 (average 59.9) years. Perioperative complication occurred in 312 cases (27.2%), including 140 cases of pulmonary infection and 53 cases of abdominal infection. Multivariate Logistic regression analysis showed that ≥65 years old (OR:0.736, 95%CI: 0.558 to 0.971, P=0.030), serum albumin less than 35 g/L(OR:2.626, 95%CI: 1.479 to 4.665, P=0.001), Borrmann type IIII((OR: 0.748, 95%CI: 0.610 to 0.917, P=0.005), tumor site at upper 1/3 of stomach (OR:1.326, 95%CI:1.167 to 1.506, P=0.000), combined organ resection(OR:0.624, 95%CI:0.428 to 0.909, P=0.014) were independent risk factors of perioperative complication. Tumor site at upper 1/3 of stomach (OR:1.649, 95%CI: 1.368 to 1.988, P=0.000), ≥65 years old (OR:0.548, 95%CI:0.379 to 0.792, P=0.001), without intraoperative chemotherapy (OR:1.671, 95%CI:1.146 to 2.437, P=0.008) were independent risk factors of perioperative pulmonary infection; Borrmann type IIII((OR:0.576, 95%CI:0.369 to 0.900, P=0.015), with intraoperative chemotherapy (OR:0.431, 95%CI:0.230 to 0.810, P=0.009), intraoperative blood loss ≥400 ml(OR:0.411, 95%CI:0.176 to 0.959, P=0.040) and combined organ resection (OR:0.412, 95%CI:0.215 to 0.789, P=0.008) were independent risk factors of perioperative intraperitoneal infection. Cox regression analysis revealed that without intraoperative chemotherapy, proximal subtotal or total gastrectomy, TNM stage III(, N3 stage lymph node metastasis, positive soft tissue outside lymph node, combined organ resection and organ failure were independent risk factors affecting the prognosis of gastric cancer patients after radical resection (all P<0.05), however the perioperative complication was not independent risk factor affecting the prognosis (P=0.259). The median survival time was 35 months, and 5-year survival rate was around 38.7%. The median survival time of gastric cancer patients with operative complications and without complications were 28.0 and 36.5 months, and the 5-year survival rates were 37.2% and 39.3%, whose difference was not statistically significant (P=0.259).

CONCLUSIONThere is a higher risk of perioperative complication in those gastric cancer patients with old age, preoperative low serum albumin level, tumor site at upper 1/3 of stomach, Borrmann type IIII(, intraoperative combined organ resection, while the perioperative complication has no significant effects on the long-term survival.

Objective To explore the effects of quality improvement in delivery room resuscitation on very/extremely low birth-weight infants (VLBWI/ELBWI). Methods A retrospective analysis was performed to analyze the clinical data of VLBWI/ELBWI who were admitted to the Neonatal Intensive Care Unit (NICU) of Nanjing Maternity Hospital Affiliated to Nanjing Medical University from January to December 2015 (pre-improvement group, n=176) and of those who were admitted from January to December 2016 after the implementation of quality improvement program on delivery room resuscitation (post-improvement group, n=199). Several parameters were monitored, including resuscitation modalities [continuous positive airway pressure (CPAP) , peak inspiratory pressure (PIP)+positive end expiratory pressure (PEEP) with T-piece resuscitator and intubation rate in delivery room], neonatal body temperature and pH on NICU admission, respiratory outcomes, morbidity from intraventricular hemorrhage, necrotizing enterocolitis, retinopathy ofprematurity and hospitalization. Chi-square (or Fisher's exact test), t or rank Sum test was used for statistical analysis. Results There was no significant difference in gestational age, birth weight, gender proportion, delivery mode and Apgar scores between the two groups (all P>0.05). After implementing the quality improvement program, there was an increased overall usage of CPAP [85.9% (171/199) vs 66.3% (112/176), χ2=19.881, P<0.01] and PIP+PEEP with T-piece resuscitator [33.8% (67/199) vs 10.8% (12/176), χ2=19.819, P<0.01], but a decreased usage of balloon catheter ventilation [6.0% (12/199) vs 39.3% (44/176), χ2=53.682, P<0.01]. No significant change in intubation rate was observed(P>0.05). The average admission temperature increased after launching the quality improvement program [M (P25-P75), 36.2 (35.8-36.5) vs 35.6 (35.4-35.7)℃ , Z= - 9.681, P<0.01]. The morbidities of pulmonary hemorrhage within one week after birth [1.5% (3/199) vs 5.1% (9/176),χ2=3.921] and grade Ⅲ / Ⅳ intraventricular hemorrhage [1.1% (2/199) vs 11.9% (21/176), χ2=33.885] decreased along with the improvement in delivery room resuscitation (both P<0.05). The duration of invasive ventilation decreased as well [3 (1-6) vs 4 (2-9) d, Z= - 2.286, P<0.05]. Conclusions Quality improvement in delivery room resuscitation measures standardizes the management of delivery room resuscitation and improves the clinical outcomes of VLBWI/ELBWI.

OBJECTIVETo detect potential mutation of iduronate-2-sulfatase (IDS) gene in a family affected with mucopolysaccharidosis type Ⅱ (MPS Ⅱ).

METHODSFor the proband and his unaffected mother, the whole coding sequence of the IDS gene was analyzed with PCR and bidirectional Sanger sequencing.

RESULTSA novel splicing mutation, c.709-1G>A, was detected in the proband, for which his mother was heterozygous.

CONCLUSIONThe c.709-1G>A splicing mutation of the IDS gene is probably causative for the MSP Ⅱ in the proband. Prenatal diagnosis for the mutation may avoid birth of further child affected with this disease.
