BACKGROUND:Type 2 diabetes mellitus impairs renal function,and studies have shown that exercise interventions can protect the kidneys.Irisin can protect renal function in diabetic nephropathy patients by restoring autophagy through inhibition of the phosphoinositide 3-kinase(PI3K)/protein kinase B(Akt)/mammalian target of rapamycin(mTOR)signaling pathway. OBJECTIVE:To explore whether exercise can restore autophagy and ameliorate renal injury by inhibiting over-activation of the renal PI3K/Akt/mTOR signaling pathway,as well as to analyze the differences in the effects of different modalities of exercise. METHODS:Six-week-old Sprague-Dawley rats were randomly divided into a blank control group(normal rats)and a diabetic group,and then the diabetic group was randomly divided into a diabetic model group,a moderate-intensity continuous exercise group,and a high-intensity intermittent exercise group after successful modeling using high-fat,high-sugar feeding plus intraperitoneal administration of low-dose 1%streptozotocin(30 mg/kg).The two exercise groups were subjected to 8 weeks of exercise intervention with different exercise intensities.The fasting blood glucose concentration was detected by glucose oxidase method,glycated hemoglobin levels was measured using a kit,serum insulin concentration was detected by Elisa method,and insulin resistance index was calculated.Gene expression of PI3K,AKT,mTOR,Beclin-1,podocin,and nephrin was detected by RT-PCR.Protein expression of mTOR and autophagy marker proteins LC3-1,LC3-2,and Beclin-1 was detected by western blot RESULTS AND CONCLUSION:Fasting blood glucose and glycosylated hemoglobin levels were highly significantly increased,insulin resistance levels were significantly increased,and insulin levels were significantly decreased in type 2 diabetic rats.Both exercises resulted in highly significant decreases in fasting blood glucose and glycosylated hemoglobin levels,significant decreases in insulin resistance levels and significant increases in insulin levels in type 2 diabetic rats.Insulin levels were significantly higher in the high-intensity intermittent exercise group compared with the moderate-intensity continuous exercise group.The expression of podocin and nephrind genes was significantly reduced in type 2 diabetic rats and two different forms of exercise significantly the gene expression.There was a further trend toward an increase in gene expression of podocyte-associated proteins in the moderate-intensity continuous exercise group compared with the high-intensity intermittent exercise group,but there was no significant difference.The mRNA and protein expression of PI3K,AKT and mTORC1 in kidney tissues of type 2 diabetic rats were significantly increased,and the expression of autophagy marker proteins Beclin-1 and LC3-2 and LC3-2/LC3-1 were significantly decreased.Both different forms of exercise significantly decreased the mRNA and protein expression of PI3K,AKT,and mTORC1,and significantly increased the autophagy marker proteins Beclin-1,LC3-2,and LC3-2/LC3-1 in renal tissues.Compared with the moderate-intensity continuous exercise group,there was a trend toward further decreases in mRNA expression of PI3K,AKT,and mTORC1 and protein expression of mTOR,and a trend toward further elevation of Beclin-1,LC3-2,and LC3-2/LC3-1 in the high-intensity intermittent exercise group,but only Beclin-1 showed a significant difference between groups.In summary,renal podocyte injury in type 2 diabetes mellitus with suppressed autophagy is closely related to aberrant activation of the PI3K/AKT/mTORC1 signaling pathway.Both moderate-intensity continuous exercise and high-intensity intermittent exercise can protect the diabetic kidney,reduce podocyte damage,and restore renal podocyte autophagy,which may be achieved by inhibiting the excessive activation of the PI3K/AKT/mTOR signaling pathway.High-intensity intermittent exercise shows a trend toward more favorable restoration of autophagy compared with moderate-intensity continuous exercise,but with a slight decrease in podocyte protein expression.

ObjectiveTo investigate the value of noninvasive imaging detection （FibroScan）， two serological models of gamma-glutamyl transpeptidase-to-platelet ratio （GPR） score and S index， and two inflammatory factors of interleukin-6 （IL-6） and tumor necrosis factor-α （TNF-α） in predicting liver fibrosis in patients with HBeAg-positive chronic hepatitis B （CHB）， as well as the consistency of liver biopsy in pathological staging， and to provide early warning for early intervention of CHB. MethodsA retrospective analysis was performed for 131 HBeAg-positive CHB patients who underwent liver biopsy in The Third People’s Hospital of Kunming from January 2019 to December 2023. The results of liver biopsy were collected from all patients， and related examinations were performed before liver biopsy， including total bilirubin， alanine aminotransferase， platelet count， gamma-glutamyl transpeptidase， albumin， IL-6， TNF-α， liver stiffness measurement （LSM）， and abdominal ultrasound. An analysis of variance was used for comparison of normally distributed continuous data between groups， and the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between groups； the chi-square test was used for comparison of categorical data between groups. A Kappa analysis was used to investigate the consistency between LSM noninvasive histological staging and pathological staging based on liver biopsy， and the Spearman analysis was used to investigate the correlation between each variable and FibroScan in the diagnosis of liver fibrosis stage. The Logistic regression analysis was used to construct joint predictive factors. The receiver operating characteristic （ROC） curve was used to evaluate the value of each indicator alone and the joint predictive model in the diagnosis of liver fibrosis， and the Delong test was used for comparison of the area under the ROC curve （AUC）. ResultsIn the consistency check， inflammation degree based on liver biopsy had a Kappa value of 0.807 （P<0.001）， and liver fibrosis degree based on liver biopsy had a Kappa value of 0.827 （P<0.001）， suggesting that FibroScan noninvasive histological staging and liver biopsy showed good consistency in assessing inflammation degree and liver fibrosis stage. Age was positively correlated with LSM， GPR score， S index， IL-6， and TNF-α （all P<0.05）， and GPR score， S index， IL-6， and TNF-α were positively correlated with LSM （all P<0.05）. GPR score， S index， IL-6， and TNF-α were all independent risk factors for diagnosing significant liver fibrosis （≥S2） and progressive liver fibrosis （≥S3） （all P<0.05）. As for each indicator alone， GPR score had the highest value in the diagnosis of significant liver fibrosis （≥S2）， followed by S index， IL-6， and TNF-α， while S index had the highest value in the diagnosis of progressive liver fibrosis （≥S3）， followed by GPR score， TNF-α， and IL-6. The joint model had a higher predictive value than each indicator alone （all P<0.05）. ConclusionThere is a good consistency between FibroScan noninvasive histological staging and pathological staging based on liver biopsy. GPR score， S index， IL-6， and TNF-α are independent risk factors for evaluating different degree of liver fibrosis in CHB， and the combined prediction model established by them can better diagnose liver fibrosis.

Objective: To develop a simple digital chylous plasma device and validate its ability to accurately, standardly, and non-destructively determine chylous plasma in blood banks and clinical transfusions in hospitals. Methods: A digital chylous plasma assessment device was designed and manufactured. This device was used to measure the chylous degrees of chylous plasma samples before freezing, after freeze-thawing, before viral inactivation, and after viral inactivation. The measured chylosity index values were categorized according to the requirements specified in Appendix A of the Chinese national standard GB 18469-2001 "Quality Requirements for Whole Blood and Blood Components". This process established a digital standard for chylous plasma, enabling the identification of severe, moderate and mild chylous plasma, and non-chylous plasma. Results: The initial simple product of the digital chylous assessment device was successfully designed and manufactured. There was no significant difference in the degree of chylous plasma between pre-freezing 468.11±217.73 lux and post-thawing 538.91±273.39 lux of chylous plasma (P>0.05), or between pre-viral inactivation 858.33±387.79 lux and post-viral inactivation 928.33±166.51 lux of chylous plasma (P>0.05). The median of chylous degree values for plasma chylous index grades 0 to 6 were 45 lux, 250 lux, 620 lux, 835 lux, 1 130 lux, 1 390 lux, and 1 700 lux, respectively. The defined cutoff values/ranges for the chylous degree values corresponding to plasma chylous index grade 0 to 6 were ≤125 lux, 126-465 lux, 466-740 lux, 741-1 000 lux, 1 001-1 233 lux, 1 234-1 560 lux, and ≥1 561 lux. Conclusion: This study successfully developed the initial product of the digital chylous device and established digital standards for classifying chylous plasma. The device demonstrates the potential to meet the needs for assessment of chylous plasma in both blood banks and clinical transfusions in hospitals, thereby promoting the development and application of standardized, non-destructive chylous plasma assessment technology.

Objective:To investigate the effects of low-frequency and high frequency repetitive transcranial magnetic stimulation (rTMS) combined with levodopa and benserazide hydrochloride on mild cognitive impairment in patients with Parkinson disease (PD).Methods:Totally 90 PD patients with mild cognitive impairment who visited from January 2020 to June 2022 were included , and they were divided into a simple drug group ( n=30), drug+ low-frequency group ( n=30), and drug+ high-frequency group ( n=30) according to the order of admission.The patients in the simple drug group were treated with oral levodopa and benserazide hydrochloride, while the patients in drug+ low-frequency and drug+ high-frequency groups were treated with low-frequency or high-frequency rTMS on the basis of oral levodopa and benserazide hydrochloride.Montreal cognitive assessment(MoCA), digital span (DS), Chinese auditory learning test (CALT), the judgment of line orientation test (JLOT) and verbal fluency test (VFT) were used to evaluate the cognitive function of patients before and after 4 weeks of treatment.SPSS 26.0 was used for statistical analysis.The paired t-test was used for intra-group comparison before and after treatment, while one-way ANOVA was used for inter-group comparison. Results:There were no significant differences in MoCA, DS anterograde, DS backward, CALT immediate recall, CALT delayed recall, JLOT, and VFT scores among patients in the simple drug group before and after 4 weeks of treatment( t=-1.157, -0.648, -0.215, -0.290, -0.154, -0.782, -0.960, all P>0.05). After 4 weeks of treatment, MoCA, DS anterograde, DS backward, CALT immediate recall, CALT delayed recall, JLOT and VFT scores in drug+ low-frequency group and drug+ high-frequency group were higher than before treatment (drug+ low frequency group: t=-16.357, -11.379, -7.999, -11.805, -16.624, -15.996, -17.241, all P<0.05; drug+ high-frequency group: t=-25.198, -13.971, -13.904, -25.831, -26.382, -20.108, -15.643, all P<0.05). There were no statistically significant differences in the scores of MoCA, DS anterograde, DS backward, CALT immediate recall, CALT delayed recall, JLOT and VFT among the three groups before treatment (all P>0.05). After treatment, there were statistically significant differences in the scores of MoCA, DS anterograde, DS backward, CALT immediate recall, CALT delayed recall, JLOT and VFT among the three groups (simple drug group : (20.37±1.96), (4.37±1.19), (2.80±0.55), (6.93±1.70), (5.17±1.09), (15.50±2.69), (10.73±1.55); drug+ low-frequency group: (23.83±2.32), (5.87±0.94), (3.87±0.73), (9.17±1.74), (8.13±1.50), (20.77±2.19), (13.30±1.73); drug+ high-frequency group: (27.17±1.64), (6.73±1.01), (4.80±0.81), (11.20±2.06), (10.03±1.54), (25.17±3.14), (15.87±2.05)) (all P<0.05). Further analysis showed that both the drug+ low-frequency and drug+ high-frequency groups had higher scores than the simple drug group, and the drug+ high-frequency group had higher scores than the drug+ low-frequency group(all P<0.05). Conclusion:The combination of drug+ low-frequency or drug+ high-frequency rTMS and drug therapy can help improve cognitive function in patients with PD, and the efficacy of drug+ high-frequency rTMS may be more significant, which provides a new therapeutic idea for clinical treatment of patients with PD.

Objective To explore the phenotypic conversion of regulatory T cells (Tregs) in the lungs of mice with bronchopulmonary dysplasia (BPD)-affected mice. Methods A total of 20 newborn C57BL/6 mice were divided into air group and hyperoxia group, with 10 mice in each group. The BPD model was established by exposing the newborn mice to hyperoxia. Lung tissues from five mice in each group were collected on postnatal days 7 and 14, respectively. Histopathological changes of the lung tissues was detected by HE staining. The expression level of surfactant protein C (SP-C) in the lung tissues was examined by Western blot analysis. Flow cytometry was performed to assess the proportion of FOXP3⁺ Tregs and RORγt⁺FOXP3⁺ Tregs in CD4⁺ lymphocytes. The concentrations of interleukin-17A (IL-17A) and IL-6 in lung homogenate were measured by using ELISA. Spearman correlation analysis was used to analyze the correlation between FOXP3⁺Treg and the expression of SP-C and the correlation between RORγt⁺FOXP3⁺ Tregs and the content of IL-17A and IL-6. Results The hyperoxia group exhibited significantly decreased levels of SP-C and radical alveolar counts in comparison to the control group. The proportion of FOXP3⁺Tregs was reduced and that of RORγt⁺FOXP3⁺Tregs was increased. IL-17A and IL-6 concentrations were significantly increased. SP-C was positively correlated with the expression level of RORγt⁺FOXP3⁺ Tregs. RORγt⁺FOXP3⁺ Tregs and IL-17A and IL-6 concentrations were also positively correlated. Conclusion The number of FOXP3⁺ Tregs in lung tissue of BPD mice is decreased and converted to RORγt⁺ FOXP3⁺ Tregs, which may be involved in hyperoxy-induced lung injury.

Objective To establish a simultaneous detection approach for 34 emerging contaminants(ECs)in tap water by liquid chromatography-tandem mass spectrometry(HPLC-MS/MS).Human health risk assessment was performed according to the detection results from 43 tap water samples.Methods Tap water samples were concentrated and extracted by solid phase extraction,and then blown to near dry by nitrogen at 40℃.The sample extracts were dissolved in methanol-water solution(95:5,VN)to 0.5 mL for analyzing.Agilent Jet Stream Electrospray Ionization(AJS ESI)and the multiple reaction monitoring(MRM)mode were performed for MS to acquire the data of 34 ECs.A database including precursor ion,product ion and retention times was established accordingly.Results The average linear correlation coefficients(r)of 34 kinds of ECs was 0.995 9.The limits of detection were 0.01～0.60 ng/L and the recoveries were between 60.7％and 119.8％.The intra-group precisions were between 0.05％～9.89％and the intra-day precisions were between 0.20％～14.40％for the spiked samples.The method was applied to analyze 43 tap water samples and a total of 15 ECs were detected.According to the results,the detection rate of caffeine was the highest(84％),and the concentration range was ND～74.42 ng/L.Among all the ECs detected,1,2,3-benzotriazole had the highest concentration(ND～361.15 ng/L),where detection rate was 44％.Humans may be exposed to these ECs by drinking the tap water.The human health risk assessments of 12 kinds of ECs were carried out,however,the estimated risk was negligible(risk quotient＜0.01).Conclusion The method is simple,highly sensitive and selective,and could meet the detection needs of ECs at trace level in tap water.There was no human health risk posed for ECs identified in 43 tap water samples analyzed by this method.

Objective:To evaluate the role of cancerous inhibitor of protein phosphatase 2A (CIP2A) in preoperative sleep deprivation (PSD)-induced aggravation of postoperative cognitive dysfunction (POCD) in aged mice.Methods:One hundred and ten healthy C57BL/6J mice of either sex, aged 18-20 months, weighing 29-35 g, were divided into 5 groups ( n=22 each) using a random number table method: sham operation group (S group), abdominal surgery group (O group), PSD + abdominal surgery group (D+ O group), CIP2A shRNA + abdominal surgery group (CS+ O group), and CIP2A shRNA+ PSD+ abdominal surgery group (CS+ D+ O group). At 14 days before surgery, control shRNA lentivirus was injected into the hippocampus in S, O and CS+ O groups, and CIP2A shRNA was injected into the hippocampus in D+ O and CS+ D+ O groups. PSD was carried out for 3 consecutive days prior to surgery. Cognitive function was assessed using the Morris water maze test at days 7-11 after surgery. The mice were sacrificed under deep anesthesia at day 3 after surgery, and hippocampal tissues were obtained to determine the expression of CIP2A, high mobility group box 1 (HMGB1), ionized calcium-binding adapter molecule 1 (Iba-1), alpha subunit of protein phosphatase 2A (PP2Aa), catalytic subunit of protein phosphatase 2A (PP2Ac), phosphorylated tau protein (p-tau) (S396), and p-tau (S404) (by Western blot), levels of reactive oxygen species (ROS), malondialdehyde (MDA), and superoxide dismutase (SOD), and count of Iba-1 positive cells in the hippocampal CA1 region (using immunofluorescence staining). Results:Compared with S group, the escape latency was significantly prolonged, the frequency of crossing the platform was reduced, duration of stay in the target quadrant was shortened, the expression of CIP2A, Iba-1 and HMGB1 was up-regulated, PP2Ac expression was down-regulated, levels of ROS and MDA and count of Iba-1 positive cells were increased, and the activity of SOD was decreased in O group ( P<0.05). Compared with O group, the escape latency was significantly prolonged, the frequency of crossing the platform was reduced, duration of stay in the target quadrant was shortened, the expression of CIP2A, Iba-1 and HMGB1 was up-regulated, PP2Ac expression was down-regulated, levels of ROS and MDA and count of Iba-1 positive cells were increased, and the activity of SOD was decreased in D+ O group, and the escape latency was significantly shortened, the frequency of crossing the platform was increased, duration of stay in the target quadrant was prolonged, the expression of CIP2A, Iba-1 and HMGB1 was down-regulated, PP2Ac expression was up-regulated, levels of ROS and MDA and count of Iba-1 positive cells were decreased, and the activity of SOD was increased in CS+ O group ( P<0.05). Compared with D+ O group, the escape latency was significantly shortened, the frequency of crossing the platform was increased, duration of stay in the target quadrant was prolonged, the expression of CIP2A, Iba-1 and HMGB1 was down-regulated, PP2Ac expression was up-regulated, levels of ROS and MDA and count of Iba-1 positive cells were decreased, and the activity of SOD was increased in CS+ D+ O group ( P<0.05). There was no significant difference in PP2Aa expression among the five groups ( P>0.05). Conclusions:The mechanism by which PSD aggravates POCD is related to up-regulating the expression of CIP2A and promoting oxidative stress responses, neuroinflammatory responses and phosphorylation of tau protein in aged mice.

Diabetes mellitus(DM)is an endocrine metabolic disease mainly characterized by chronic hyperglycemia,which seriously threatens the health and quality of life of human beings,and with the improvement of living standard and unhealthy lifestyle in China,the incidence of DM continues to rise and tends to be younger,so it is urgent to carry out in-depth research on hypoglycemic treatment.DM is pathologically based on absolute or relative insulin deficiency,and there is no radical cure for it,and Western medicine mostly adopts insulin injection or oral hypoglycemic drugs for symptomatic treatment,which is effective but prone to toxic side effects in long-term use.Chinese medicine has the advantages of multi-path and multi-target in treating DM,and plays a role in lowering blood sugar by promoting insulin secretion,improving insulin resistance,regulating glucolipid metabolism and anti-oxidative stress,etc.Its efficacy is remarkable and the rate of toxic side effects is low.In recent years,there have been more studies on the mechanism of action of traditional Chinese medicine and compound prescriptions on animal models of DM.By reviewing the relevant literature in recent years,the author has systematically sorted out the mechanism of hypoglycemic action of single Chinese medicine,traditional Chinese medicine compound prescriptions,effective components of traditional Chinese medicine and their related experimental designs,from promoting insulin secretion,inhibiting gluconeogenesis,promoting glycogen synthesis,improving insulin resistance,inhibiting glycosidase activity,alleviating oxidative stress damage,inhibiting inflammatory response and regulating intestinal stress.The study and experimental design of the hypoglycemic mechanism of Chinese medicine were summarized in terms of promoting insulin secretion,inhibiting gluconeogenesis,promoting glycogen synthesis,improving insulin resistance,inhibiting glucosidase activity,alleviating oxidative stress damage,inhibiting inflammatory response and regulating intestinal flora,etc.,with a view to providing reference for the wider clinical application of Chinese medicine in hypoglycemia and its in-depth pharmacodynamic study.
