Type 2 diabetes mellitus(T2DM)can lead to changes in brain structure and function,increasing the risk of cognitive impairment and dementia.The mechanism may be related to insulin resistance(IR),impaired insulin signal transduction,and cerebral vascular disease.Glucagon-like peptide 1 receptor agonists(GLP-1RAs)are a class of new drugs in treating T2DM,which can lower blood glucose,delay gastric emptying,and increase satiety,thereby reduce body weight.In recent years,more and more researchers have conducted animal experiments and clinical trials to explore the effects of GLP-1RAs,especially Liraglutide and Exenatide,on cognitive function in patients with T2DM and related mechanisms.This review summarizes the effects of GLP-1RAs on cognitive function in patients with T2DM and their possible mechanisms.

Objective:To investigate the role of serotonin reuptake transporter(SERT)and P2X3 receptor of dorsal root ganglion(DRG)in regulating visceral hypersensitivity of rats with irritable bowel syndrome(IBS)by electroacupuncture(EA). Methods:Male Sprague-Dawley and SERT-/-rats were subjected to preparing IBS visceral hypersensitivity models with 2,4,6-trinitrobenzene sulfonic acid(TNBS)enema.Three weeks post-modeling,interventions including EA,intrathecal injection,and EA plus intrathecal injection were applied,respectively.Hematoxylin-eosin staining and abdominal withdrawal reflex(AWR)score were used to confirm the successful establishment of the IBS model.AWR score,whole-cell patch clamp technique,and Western blotting assay were used to evaluate the changes in visceral pain sensitivity,electrophysiological properties of DRG neurons,and the expression of DRG P2X3 receptor and SERT in IBS rats. Results:Compared to the model group,the AWR score in the EA group decreased significantly(P<0.05),the resting membrane potential(P<0.05)and the number of action potentials(P<0.05)of DRG neurons reduced,and the baseline intensity increased(P<0.05);additionally,the expression of P2X3 receptor in DRG decreased(P<0.01),and the SERT expression increased(P<0.05).Compared to the P2X3 receptor agonist group,the SERT protein expression in DRG was higher in the EA group.In SERT-/-rats,the P2X3 receptor expression in DRG increased in the EA group compared to the model group(P<0.01). Conclusion:EA modulates the electrophysiological characteristics of intestinal primary sensory neurons by regulating the expression of SERT and P2X3 receptor in DRG of IBS rats.This modulation may contribute to the mechanism by which EA alleviates peripheral sensitization of visceral pain in IBS rats.

OBJE CTIVE To establish a method for quality evaluation of Xin ’an capsule by combining fingerprint , multi-component quantitative analysis and chemical pattern recognition analysis. METHODS High performance liquid chromatography(HPLC)combined with Similarity Evaluation System of TCM Chromatogram Fingerprint (2012 edition)were used to establish the fingerprints of 24 batches of Xin ’an capsules and evaluate the similarity. The common peaks were determined. The contents of glucosylvitexin ,rhamnosylvitexin,vitexin,hyperoside and isoquercetin in Xin ’an capsules were determined by the same HPLC method. Taking the common peak area of fingerprint as the variable ,MetaboAnalyst 5.0 tool was used to draw the cluster analysis (CA)heat map. SIMCA 14.1 software was used to perform principle component analysis (PCA)and partial least squares-discriminant analysis (PLS-DA). RESULTS Twelve common peaks were identified with the similarity greater than 0.97. Six common peaks were identified as chlorogenic acid ,glucosylvitexin,rhamnosylvitexin,vitexin,hyperoside and isoquercetin.The linear range of glucosylvitexin ,rhamnosylvitexin,vitexin, hyperoside and isoquercetin were 2.36-151.35,9.15-585.20, 1.20-76.50, 0.68-43.20, 0.44-27.90 µg/mL(all r>0.999).RSDs of precision ,repeatability and stability (24 h)tests were 163.com all less than 2.00% . The average recoveries were 95.80%(RSD=0.96% ,n=6),102.10% (RSD=0.93% ,n=6), 103.26%(RSD=1.28%,n=6),103.89%(RSD=0.73%,n=6) and 102.09%(RSD=1.79%,n=6),respectively. The contents of the five components were 0.988 8-1.559 1,4.336 6-11.220 1, 0.065 1-0.830 5,0.043 8-0.692 5 and 0.023 2-0.427 2 mg/grain,respectively. The results of CA and PCA showed that 24 batches of samples could be divided into three categories ,i.e. S 1-S15,S16-S18 and S 19-S24. PLS-DA showed that variable importance in projection values of the corresponding component of peak 6 and glucosylvitexin (peak 7),rhamnosylvitexin(peak 8),hyperoside (peak 10) and isoquercetin (peak 11) were greater than 1. CONCLUSIONS The established HPLC fingerprint and multi-component quantitative method are simple and feasible. Combined with chemical pattern recognition analysis ,it can be used for the quality control of Xin ’an capsules. Glucosylvitexin ,rhamnosylvitexin and other components may be differentital markers affecting the quality of each batch of samples.
5.Efficacy of different surgical treatments for hypertensive cerebral hemorrhage in older adult patients and their effects on traumatic stress and cerebral edema
Chinese Journal of Primary Medicine and Pharmacy 2022;29(12):1765-1770
Objective:To investigate the efficacy of different surgical treatments for hypertensive cerebral hemorrhage in older adult patients and their effects on traumatic stress and cerebral edema.Methods:A total of 100 older adult patients with hypertensive cerebral hemorrhage who received treatment in Zhejiang Xin'an International Hospital from January 2018 to June 2020 were included in this study. They underwent either craniotomy (craniotomy group, n = 50) or hard channel minimally invasive puncture drainage (minimally invasive puncture group, n = 50) according to the willingness of patients and their close relatives. Perioperative indexes, Barthel index after treatment, nerve injury indexes before and after treatment, prognosis related indexes, trauma stress indexes and brain edema were compared between the two groups. Results:Operative time, intraoperative blood loss and postoperative hospital stay in the craniotomy group were (147.21 ± 31.35) minutes, (289.74 ± 22.75) mL and (42.74 ± 6.82 ) days, respectively, which were significantly longer or greater than (41.88 ± 7.19) minutes, (4.62 ± 0.88) mL and (16.27 ± 4.02) days in the minimally invasive puncture group ( t = 38.73, 62.17, 23.17, all P < 0.001). Barthel index at 1 and 3 months after treatment in the minimally invasive puncture group was (63.11± 9.64) and (93.51 ± 11.38), respectively, which was significantly greater than (44.78 ± 8.85) and (81.29 ± 10.37) in the craniotomy group ( t = 3.17, 6.21, both P < 0.05). Before treatment, there were no significant differences in nerve injury index, prognosis index, trauma stress index and brain edema between the two groups (all P > 0.05). At different time points after treatment, each indicator in the minimally invasive puncture group was significantly superior to that in the craniotomy group (all P < 0.05). Conclusion:Hard channel minimally invasive puncture drainage exhibits advantages over traditional craniotomy in the treatment of hypertensive cerebral hemorrhage in older adult patients. Hard channel minimally invasive puncture drainage can more greatly reduce injury to brain tissue, better control nerve injury and brain edema, and more remarkably improve patient's quality of life than traditional craniotomy.

Objective:To investigate the influencing factors of the survival in infants with congenital diaphragmatic hernia (CDH) and to develop a prediction model for CDH.Methods:Clinical data of 252 infants with a prenatal diagnosis of CDH in Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine from January 2010 to December 2018 were retrospectively analyzed. Adverse outcomes were defined as neonatal death on discharge. Chi-square and t test were used for univariate analysis of 16 perinatal and five postnatal risk factors. Regression analysis was used to determine the independent predictors of survival. The receiver operating characteristics (ROC) curves of the risk factors for predicting the survival of CDH were drawn. A prediction model based on the combination of risk factors for predicting adverse outcomes of CDH was established using the cut-off value. ROC curves of the model were drawn and the area under curve (AUC), sensitivity, and specificity were calculated. Results:Out of the 252 patients, 173(68.7%) survived on discharge. Univariate analysis showed that lung-to-head ratio (LHR), polyhydramnios, right diaphragmatic hernia, liver herniation, intrathoracic stomach, premature birth, low birth weight, 5 min Apgar score <7, and amniotic fluid index (AFI) were significantly associated with the survival of CDH. Regression analysis showed that polyhydramnios ( OR=11.19,95% CI:2.83-45.33), liver herniation ( OR=2.81,95% CI:1.32-11.92), intrathoracic stomach ( OR=5.02, 95% CI:1.29-17.13), low birth weight ( OR=8.58,95% CI:1.59-45.01) and AFI ( OR=3.68, 95% CI:1.37-14.72) were independent risk factors for survival at discharge in children with CDH, while LHR ( OR=0.36, 95% CI:0.01-0.69) were protective factors. The predictive cut-off values of LHR, polyhydramnios, liver herniation, intrathoracic stomach, low birth weight, and AFI were 1.6, 1.0, 1.0, 1.0, 1.0, and 232.5 mm, respectively. The model based on the combination of the above indicators for predicting CDH adverse outcomes was shown with an AUC value of 0.904, predictive sensitivity of 0.747, and specificity of 0.896. Conclusions:In this study, LHR, liver herniation, intrathoracic stomach, polyhydramnios, low birth weight, and AFI are independent risk factors for CDH survival. The combination of prenatal and postnatal indicators is noted for a higher accuracy for predicting CDH survival.

Objective To analyze the present situation of glucose metabolism and the characteristics of blood glucose fluctuation in in-hospital type l diabetic patients (T1DM). Methods One hundred and forty-three hospitalized cases of T1DM patients from November 2012 to November 2016 were retrospectively analyzed.The percentage of adult-onset T1DM patients was 76.22%(109/143)and none adult-onset was 23.78%(34/143). The following data were collected: general information, the indexes of glucose metabolism and islet function.Seventy-two-hour continuous glucose monitoring(CGM) was carried on 40 patients as a subgroup.Results The average age was(40.29 ± 16.79)years.The onset age of diabetes was(33.57 ± 17.18)years.The disease duration was 4.0(1.0,10.0)years.The body mass index(BMI)was(20.68 ± 2.95)kg/m2.The fasting blood glucose(FBG)was(12.02 ± 5.40)mmol/L.The HbA1c was(9.80 ± 2.65)%.The fasting C-peptide was 0.08(0.01,0.38)nmol/L.The 2-hour postprandial C-peptide (C-P 2 h) was 0.12(0.01, 0.70) nmol/L. The anti-glutamic acid decarboxylase antibody was 12.08(8.16,20.56)μg/L.The islet-cell antibody was 4.85(2.66,12.07)μg/L.By using multivariate linear regression analysis, HbA1c were negatively related to the duration and BMI of T1DM. CGM: the mean blood glucose was (10.34 ± 2.97) mmol/L. The standard deviation of blood glucose was (2.89 ± 1.07) mmol/L. The mean amplitude glycemic excursions was (7.10 ± 3.09) mmol/L. The incidence of hypoglycemia was 10.00% (≤ 2.8 mmol/L) and 32.50% (≤ 3.9 mmol/L). Conclusions Adult-onset T1DM patients account for more than two-thirds. In-hospital T1DM patients have poor control of blood glucose, and they show the clinical characteristics of high blood glucose fluctuation and more hypoglycemia.
