ObjectiveTo explore the protective effect of glucocorticoid-induced transcription factor 1 (GLCCI1) on cognitive dysfunction in diabetic mice and its mechanism. MethodsTwenty-four C57BL/6J mice were randomly divided into 4 groups, namely Control, DM, DM+AAV-Glcci1, and DM+AAV-NC. The Control group was intraperitoneally injected with saline, while the other groups were all injected with streptozotocin (STZ). Two weeks after successful modeling, the DM+AAV-Glcci1 group was brain stereotactic injected with Glcci1 overexpressing adeno-associated virus, and the DM+AAV-NC group was stereoscopically injected with the control virus. After 12 weeks, the Morris water maze test was used to evaluate the learning and memory abilities of mice in each group. Subsequently, the localized expression of GLCCI1 in the hippocampus were determined by immunofluorescence and immunohistochemistry experiments. The myelin morphology in the hippocampus was observed by LFB staining, the neuronal morphology was observed by Nissl staining, and the myelin-related proteins MBP and CNPase were stained by immunohistochemistry. Molecular docking was used to predict the interaction between GLCCI1 and HSPA5. The expression of endoplasmic reticulum stress-related proteins was detected by Western blot. ResultsThe results of the behavioral experiment showed that compared with the mice in the Control group, DM mice exhibited obvious cognitive dysfunction behaviors (P<0.000 1), and the learning and memory abilities of mice improved after overexpression of Glcci1 (P=0.000 7). The results of immunofluorescence and immunohistochemistry showed that GLCCI1 was expressed in hippocampal neuron cells. Compared with Control mice, the expression level of GLCCI1 in DM mice was significantly downregulated (P<0.000 1). The molecular docking results revealed that GLCCI1 interacts with HSPA5. The Western blot results indicated that, compared with the Control group, the expression levels of endoplasmic reticulum stress-related proteins HSPA5 (P<0.000 1), ATF4 (P<0.000 1), ATF6 (P=0.001 1), and p-ELF2α/elF2α (P=0.000 1) in the DM group were significantly increased; Compared with the DM group, the expression of the corresponding protein HSPA5 (P<0.000 1), ATF4 (P<0.000 1), ATF6 (P=0.000 2), and p-ELF2α/elF2α (P=0.000 1) was significantly down-regulated after overexpression of Glcci1. LFB staining showed that compared with the Control group, the myelin integrity of DM mice decreased significantly (P=0.010 3), the expressions of myelin-related proteins MBP and CNPase decreased significantly (P=0.000 4, P=0.000 2), and Nissl staining observed disordered neuronal arrangement. Compared with the mice in the DM group, the myelin integrity in the hippocampal region significantly increased after overexpression of Glcci1 (P=0.000 3), the expressions of myelin-related proteins MBP and CNPase significantly increased (P=0.001 4, P=0.000 1), and the ordered arrangement of neurons was observed by Nissl staining. ConclusionThe down-regulation of GLCCI1 expression in hippocampal neurons promotes demyelination of hippocampal neurons and thereby induces diabetic cognitive dysfunction. The specific mechanism may be related to endoplasmic reticulum stress.

Pan-vascular medicine is an emerging discipline focusing on atherosclerotic diseases,with the concept of multidisciplinary integration,emphasizing on exploring the mechanism of disease development from the whole of the organism's structure and function.At present,the basic mechanism system of pan-vascular diseases has yet to be perfected.The pan-vascular concept is highly compatible with the idea of Chinese medicine that focuses on the overall view.Deficiency of all qi is the root cause of pan-vascular diseases,while phlegm,blood stasis,and water-dampness and other tangible evils stagnate in the veins and channels as the symptoms of the disease,therefore,the disease mechanism can be highly summarized as"stagnation due to qi deficiency".Deficiency leads to the stagnation,blocking the veins and channels,and the deficiency worsens due to the stagnation and then damages the veins and channels,thus,it develops into a disease.Based on the theory of"stagnation due to qi deficiency",this paper takes endothelial cell dysfunction as the entry point of pan-vascular diseases,and considers that low endothelial cell immunity is the initiating factor of pan-vascular diseases,and that the widespread persistence of microinflammatory state is the key pathology to pan-vascular diseases.

Although the development of COVID-19 vaccines has been a remarkable success, the heterogeneous individual antibody generation and decline over time are unknown and still hard to predict. In this study, blood samples were collected from 163 participants who next received two doses of an inactivated COVID-19 vaccine (CoronaVac®) at a 28-day interval. Using TMT-based proteomics, we identified 1,715 serum and 7,342 peripheral blood mononuclear cells (PBMCs) proteins. We proposed two sets of potential biomarkers (seven from serum, five from PBMCs) at baseline using machine learning, and predicted the individual seropositivity 57 days after vaccination (AUC = 0.87). Based on the four PBMC's potential biomarkers, we predicted the antibody persistence until 180 days after vaccination (AUC = 0.79). Our data highlighted characteristic hematological host responses, including altered lymphocyte migration regulation, neutrophil degranulation, and humoral immune response. This study proposed potential blood-derived protein biomarkers before vaccination for predicting heterogeneous antibody generation and decline after COVID-19 vaccination, shedding light on immunization mechanisms and individual booster shot planning.

Objective:To explore the status quo and influencing factors of self-management behavior of patients with diabetic retinopathy (DR) based on the ABC-X model.Methods:Totally 315 DR patients who were hospitalized in the Department of Ophthalmology of Henan Provincial People's Hospital from May to September 2022 were selected by convenience sampling and investigated with the general information questionnaire, Summary of Diabetes Self-Care Activities (SDSCA), Diabetes Distress Scale (DDS) and Social Support Rating Scale (SSRS). A total of 315 questionnaires were distributed, and 305 valid questionnaires were recovered, with an effective recovery rate of 96.8%.Results:The SDSCA, DDS and SSRS scores of 305 DR patients were (39.59±9.49), (37.44±10.53) and (37.42±3.65), respectively; self-management behavior was positively correlated with the number of hospitalizations and social support ( P<0.01), negatively correlated with psychological distress ( P<0.01). The results of multiple linear regression analysis showed that the type of residence, course of disease, number of hospitalizations, psychological distress of diabetes and social support were the influencing factors of self-management behavior of DR patients ( P<0.05) . Conclusions:The level of self-management behavior of DR patients is yet to be improved. Medical and nursing staff should provide targeted interventions to improve their quality of life and prognosis.

OBJECTIVE To compare t he diff erences of the fingerprint and in vitro antioxidant activity between decoction pieces of Polygonum cuspidatum by integrated technology of habitat processing and processing (short for IPDP )and traditional processing decoction pieces (short for TPDP ). METHODS Ten batches of IPDP and ten batches of TPDP were prepared by integrated technology and traditional technology ,respectively. HPLC method was used to establish and compare the fingerprints of IPDP and TPDP. The scavenging rates of DPPH free radical ,ABTS free radical ,superoxide free radical and hydroxyl free radical and reducing activity of Fe 3+ were detected for IPDP and TPDP. In vitro antioxidant activities were compared between IPDP and TPDP. RESULTS There were 11 common peaks in the fingerprints of IPDP and TPDP ,among which 17 came from IPDP and 13 came from TPDP. The peak heights of peak 6(polydatin)and peak 15(emodin-8-O-β-D-glucoside)in IPDP were significantly higher than those in the TPDP ,and the peak heights of peak 13(resveratrol),peak 17(emodin)and peak 19(physcion)in the TPDP were significantly higher than those in the IPDP. The results of in vitro antioxidant test showed that IPDP and TPDP had a certain scavenging capacity on DPPH free radical ,ABTS free radical ,superoxide free radical and hydroxyl free radicals ,and also had a certain reducing capacity on Fe 3+. CONCLUSIONS The integrated processing technology of P. cuspidatum has a good retention effect on the glycosides in P. cuspidatum ,and the in vitro antioxidant activity of IPDP is stronger than that of TPDP.

Objective:To explore an ideal method for establishing a mouse model of chronic atrophic gastritis (CAG).Methods:CAG mouse models were established with five different modeling methods ( N-methyl- N′-nitro- N-nitrosoguanide (MNNG), sodium salicylate, sodium deoxycholate, Helicobacter pylori infection, and combinations of them) in BALB/c and C57 mice. The effect of each modeling method was evaluated by histological observation of gastric mucosa, plasma biochemical parameters, inflammatory response score, and the expression of anti-inflammatory factors. Results:The results of histological observation of gastric mucosa showed that all of the 5 methods could successfully establish CAG mouse models. In BALB/c mice, compared with the healthy control group, significant features of CAG accompanied with intestinal metaplasia was found in the model group established by combination of MNNG-free drinking, 2% sodium salicylate and 20 mmol sodium deoxycholate. From the results of serological detection, compared with the normal control group, the mRNA expression levels of related anti-inflammatory factors interleukin-2, interleukin-10, interleukin-13 and growth differentiation factor-15 of each model group decreased, which indicated that the mice of each CAG model group had different degrees of inflammation. The results of plasma biochemical parameters indicated that plasma gastrin of each group decreased and the ratio of pepsinogen Ⅰ and pepsinogen Ⅱ significantly dropped. The above results demonstrated that in BLAB/c mice, MNNG-free drinking, 2% sodium salicylate and 20 mmol sodium deoxycholate was better than other four modeling methods. For C57 mice, it was also found that simple chemical drug mutagenesis and Helicobacter pylori replication method both could successfully establish CAG models. No matter from pathological observation, relative expression of anti-inflammatory factors and analysis of plasma biochemical parameters, the effects of combination of the two methods was better. Conclusion:The CAG mouse model established by MNNG-free drinking, 2% sodium salicylate and 20 mmol sodium deoxycholate can provide a certain reference for the establishment and application of mouse model in CAG experiments in the future for pharmacological research.

Objective:To explore the value of blood glucose at different time points in the 7-point peripheral blood glucose spectrum in predicting asymptomatic hypoglycemia at night in elderly patients with type 2 diabetes mellitus (T2DM) based on continuous glucose monitoring system (CGMS) .Methods:From January to October 2019, convenience sampling was used to select 225 elderly T2DM patients who were hospitalized in Xinxiang Central Hospital. We monitored the peripheral blood glucose at 7 time points after admission, and performed 72-hour continuous glucose monitoring (CGM) simultaneously. We investigated the occurrence of night hypoglycemia of patients, and divided patients into night symptomatic hypoglycemia group and night asymptomatic hypoglycemia group according to the results. We compared the hypoglycemia related indicators of two groups, drew the receiver operating characteristic (ROC) curve, calculated the area under the curve (AUC) to determine the best cut-point value of each indicator and the occurrence of asymptomatic hypoglycemia at night.Results:In the CGM of 225 patients, 74 cases had hypoglycemia at night, and the incidence was 32.89%, and 34 cases of them had asymptomatic hypoglycemia at night, accounting for 45.95% (34/74) . The fasting blood glucose, blood glucose after dinner and before bedtime of patients in night asymptomatic hypoglycemia group were lower than those of night symptomatic hypoglycemia group. The best cut-off points of blood glucose before bedtime and fasting blood glucose for predicting asymptomatic hypoglycemia at night were 6.9 mmol/L and 6.0 mmol/L respectively, and the AUC were 0.822 and 0.651 respectively.Conclusions:We should be alert to the occurrence of asymptomatic hypoglycemia at night in elderly patients with T2DM. Blood glucose before bedtime <6.9 mmol/L or fasting blood glucose <6.0 mmol/L indicates an increased risk of asymptomatic hypoglycemia at night.

Objective:To investigate the effectiveness of scanning glucose monitoring system in dawn phenomenon of patients with type 2 diabetes mellitus (T2DM) based on continuous glucose monitoring system (CGMS) .Methods:A total of 45 patients with T2DM hospitalized in the Endocrine Department of Xinxiang Central Hospital from June 2019 to June 2020 were selected as the research subjects by convenience sampling method. All selected patients were asked to wear the scanning glucose monitoring system after admission, and then the CGMS for continuous glucose monitoring after 48 hours. The scanning glucose monitoring system and the CGMS were taken off at the same time after 72 hours. The blood glucose analysis report of the same period was checked to determine whether the dawn phenomenon occurred. The consistency to determine dawn phenomenon was analyzed between CGMS and scanning blood glucose monitoring by Kappa test. According to the CGMS judgment results, the receiver operating characteristic curve (ROC) of the scanning blood glucose monitoring system was drawn to evaluate the optimal tangent value of the night blood glucose for predicting dawn phenomenon and the next day fasting blood glucose for evaluating dawn phenomenon.Results:Among the 45 study subjects, there was no statistical difference in determining the incidence of dawn phenomena between CGMS and scanning glucose monitoring system [55.56% (25/45) vs. 46.67% (21/45) , χ 2=0.711, P>0.05]. Consistency analysis showed that Kappa value was 0.895, and the consistency of CGMS and scanning glucose monitoring system in judging dawn phenomenon was good (Kappa=0.895, 95% CI 1.130-4.883, P<0.01) . The optimal tangent value of night blood glucose for predicting dawn phenomenon was 8.31 mmol/L, and the optimal tangent value of the next day fasting blood glucose for evaluating dawn phenomenon was 7.25 mmol/L. The value of the area under the ROC curve were 0.729 and 0.803 respectively. Conclusions:Scanning blood glucose monitoring can accurately judge the dawn phenomenon. When the night blood glucose value is 8.31 mmol/L, it indicates that the dawn phenomenon may occur. When the next day's fasting blood glucose value is 7.25 mmol/L, it indicates that the dawn phenomenon may already occur.

Benign occupations of the liver (BOL) are a heterogeneous group of benign hepatic lesions,a minority of which may need active management.It's reported that radiofrequency ablation (RFA) can be used to treat BOL,such as hepatic haemangioma,focal nodular hyperplasia (FNH),hepatocellular adenoma,simple hepatic cyst,liver abscess and hepatic echinococcosis.RFA has exhibited a potentiality to replace resection as the first-line treatment option for hepatic haemangioma.For multiloculated intractable simple hepatic cyst or liver abscess,when patients are not suitable for or refuse surgical resection,RFA may be an alternative option for the resection;and it also has many advantages over resection,including effectiveness,safety,minimal invasiveness and repeatability in the treatment of FNH,hepatocellular adenoma,and hepatic echinococcosis.A review will be presented on the current situation and latest progression of RFA therapy for BOL in this article.
