This paper discussed the clinical ideas and methods of treating diabetes by improving symptoms. Diabetes-related symptoms can affect the control of blood glucose and other metabolic indicators to varying degrees， and affect the quality of life of patients. In the clinical diagnosis and treatment of diabetes， “equal emphasis on both indicators” is suggested， meaning that quality of life indicators is as important as metabolic indicators. The patient's symptoms should be paied attention to， and the diagnosis and treatment should start from “symptom differentiation”， and emphasize the “key symptoms”. When there are many symptoms， it is advised to adopt the combined treatment mode of “syndrome cluster”， and take the principle of “treating both the root and accompanying symptoms in mild cases with multiple symptoms， and prescribing multiple formulas daily”. At the same time， the model of co-management of three disciplines of diabetes consisting of diabetes specialists， traditional Chinese medicine doctors， and health managers can help the management of diabetes symptoms.

BACKGROUND:Mangiferin is a biphenylpyridone compound extracted from mango leaves,bark and roots.Previous studies have shown that mangiferin can exert anti-systemic inflammatory effects through the activation of transcription factors such as NF-κB and JAK/STAT. OBJECTIVE:To investigate the effects and mechanisms of mangiferin on proliferation,migration and inflammatory factor release of rheumatoid arthritis fibroblast-like synovial cells(RA-FLS). METHODS:RA-FLS were divided into blank group,R848(TLR7/8 agonists)stimulated group,mangiferin low-,medium-,high-dose groups(2,4 and 8 μg/mL)and positive control group(Cu-CPT8,TLR8 pathway inhibitor).The cytotoxic effect of different mass concentrations of mangiferin was detected using cell counting kit-8 method and the final cellular dosing mass concentration was screened.The proliferation ability of RA-FLS was detected by cell clone formation assay,the migration ability of RA-FLS was detected by scratch assay and Transwell migration assay,and the expression of interleukin 1β,interleukin 6 and tumor necrosis factor α mRNA in RA-FLS was detected by qRT-PCR. RESULTS AND CONCLUSION:Compared with the blank group,the viability of RA-FLS was inhibited after treatment with mangiferin at 2-10 μg/mL,but there was no significant difference among groups(P>0.05),indicating that the toxic effect on RA-FLS was minimal.Compared with the R848-stimulated group,mangiferin decreased the number of cell clones,the scratch healing rate and the number of migrating cells in all dosing groups(P<0.01);and the expression of interleukin 1β,interleukin 6 and tumor necrosis factor α mRNA was also reduced in the mangostin medium-and high-dose groups(P<0.01).Compared with the R848-stimulated group,the number of cell clones,the scratch healing rate and the number of migrating cells as well as the expression levels of interleukin 6 and tumor necrosis factor α mRNA were significantly reduced in the positive control group(P<0.05,P<0.01).But there was no significant difference in the expression level of interleukin 1β.To conclude,mangiferin may exert its anti-rheumatoid arthritis effects through the TLR7/8 signaling pathway by inhibiting RA-FLS proliferation,migration,and inflammatory factor release.

Objective The aim of this study was to explore the role and mechanism of ferroptosis in SiO2-induced cardiac injury using a mouse model. Methods Male C57BL/6 mice were intratracheally instilled with SiO2 to create a silicosis model.Ferrostatin-1(Fer-1)and deferoxamine(DFO)were used to suppress ferroptosis.Serum biomarkers,oxidative stress markers,histopathology,iron content,and the expression of ferroptosis-related proteins were assessed. Results SiO2 altered serum cardiac injury biomarkers,oxidative stress,iron accumulation,and ferroptosis markers in myocardial tissue.Fer-1 and DFO reduced lipid peroxidation and iron overload,and alleviated SiO2-induced mitochondrial damage and myocardial injury.SiO2 inhibited Nuclear factor erythroid 2-related factor 2(Nrf2)and its downstream antioxidant genes,while Fer-1 more potently reactivated Nrf2 compared to DFO. Conclusion Iron overload-induced ferroptosis contributes to SiO2-induced cardiac injury.Targeting ferroptosis by reducing iron accumulation or inhibiting lipid peroxidation protects against SiO2 cardiotoxicity,potentially via modulation of the Nrf2 pathway.

Objective To investigate the relationship between insomnia,gastrointestinal symptoms,and glycosylated hemoglobin(HbA1c)levels in individuals diagnosed with type 2 diabetes mellitus(T2DM),as well as the related influencing factors.Methods A total of 910 T2DM patients treated in our multicenter from January 2022 to December 2022 were enrolled in this study.General information(gender,age,smoking and drinking history,exercise,course of disease,treatment and complications),HbA1c,Athens Insomnia Scale(AIS)scores and Gastrointestinal Symptoms Rating Scale(GSRS)scores of patients were collected.The differences of sleep and gastrointestinal symptoms between groups were analyzed,and the correlation between the differences and HbA1c was analyzed.Furthermore,the risk factors for non-standard HbA1c were analyzed.Results The AIS score and GSRS score in the HbA1c control group were less than those in the non-standard group(P＜0.01).Insomnia was reported by 37.0％of T2DM patients,and the HbA1c level in the insomnia group was significantly higher than that in the non-insomnia group(10.00％±2.38％vs.8.26％±1.73％,P＜0.01).Gastrointestinal symptoms were present in 57.5％of T2DM patients,and the HbA1c levels in the group with gastrointestinal symptoms were significantly higher than those in the group without gastrointestinal symptoms(9.26％±2.23％vs.8.43％±1.98％,P＜0.01).Furthermore,26.3％of T2DM patients experienced both insomnia and gastrointestinal symptoms.Remarkably,the HbA1c levels in the group with both insomnia and gastrointestinal symptoms were significantly higher than those in the group without either condition(10.18％±2.44％vs.8.45％±1.86％,P＜0.01).Correlation analysis demonstrated a significant association between sleep quality,gastrointestinal function,and HbA1c levels(P＜0.01).The logistic regression analysis result revealed that age,GSRS score,AIS score,and the presence of insomnia combined with gastrointestinal symptoms were independent risk factors for predicting HbA1c≥6.5％(P＜0.01).Having both insomnia and gastrointestinal symptoms concurrently was the strongest risk factor for substandard HbA1c control,and the risk of blood sugar control may increase about 5 times when both appear together.Conclusion Insomnia and gastrointestinal symptoms are common comorbidities in T2DM patients,showing a cross-interfering relationship,and they appear together with poor blood sugar control,interact causally,and amplify each other.

Objective:To investigate the effects of external application of Sanying Plaster on the size of thyroid nodules and the states of depression and anxiety in patients with benign thyroid nodules.Methods:A randomized controlled trial was conducted. A total of 120 patients with benign thyroid nodules from the outpatient clinic of the Department of Thyroid Diseases at Shanghai Traditional Chinese Medicine Hospital from June to December 2022 were selected as the subjects of the study. They were divided into two groups using the random number table method, with 60 patients in each group. The control group received lifestyle intervention treatment, while the treatment group received Sanying Ointment in addition to the treatment of the control group. Both groups were treated for 3 months. TCM syndrome scores were measured before and after treatment; the maximum diameter of thyroid nodules was measured using a color Doppler ultrasound transverse section; the quality of life was assessed using the short form 36 (SF-36); the degree of anxiety and depression was evaluated using the self-rating anxiety scale (SAS) and the self-rating depression scale (SDS); adverse reactions during the treatment period were recorded, and the clinical efficacy was evaluated.Results:During the treatment period, 4 cases in the treatment group and 3 cases in the control group did not complete the treatment. Finally, 56 cases in the treatment group and 57 cases in the control group entered the efficacy evaluation. The total effective rate of the treatment group was 71.4% (40/56), and that of the control group was 14.0% (8/57), with a statistically significant difference between the two groups ( χ2=26.82, P<0.001). After treatment, the TCM syndrome score of the treatment group (10.02±3.65 vs. 16.65±3.44, t=-10.24) was lower than that of the control group ( P<0.001); the maximum diameter of thyroid nodules [11.00 (4.65, 19.93) mm vs. 15.00 (7.15, 28.50) mm, Z=-2.43] was lower than that of the control group ( P<0.05); the SF-36 score [121.83 (117.00, 130.00) vs. 114.42 (104.25, 127.50), Z=-2.62] was higher than that of the control group ( P<0.01); the SDS (46.72±4.59 vs. 57.02±5.99, t=14.80) and SAS (42.25±5.72 vs. 50.60±7.12, t=10.04) scores were lower than those in the control group ( P<0.001). The incidence of adverse reactions during the treatment period in the treatment group was 3.5% (2/57), and no adverse reactions occurred in the control group. Conclusion:The external application of Sanying Ointment helps to reduce the size of thyroid nodules in patients with benign thyroid nodules, improve the quality of life and anxiety and depression, and increase clinical efficacy with good safety.

The incidence of perioperative arrhythmias is 4%～20%in noncardiac surgery and 10%～30%in cardiothoracic surgery,with the incidence of perioperative arrhythmias in cardiac surgery patients as high as 90%.Perioperative arrhythmias can prolong hospitalization and increase morbidity and mortality during hospitalization.Studies have shown that aberrantly expressed microRNAs in cardiovascular diseases can participate in cardiac auto-maticity,excitability and conductivity by regulating ion channels,gap junction proteins,and intracellular Ca2+ handling proteins,thereby regulating cardiac electrophysiological homeostasis and arrhythmias.In this article,we will review the research progress of microRNAs and arrhythmias mainly from the perspective of cardiac electrophysi-ological imbalance.

Objective:To analyze the expression levels and clinical significance of interferon (IFN)-α/β in the renal cortex and serum of children with lupus nephritis (LN).Methods:A total of 32 children with LN diagnosed in the pediatric nephrology department of the Second Xiangya Hospital of Central South University from December 2017 to September 2020 were selected as the study subjects (LN group). The normal kidney control group consisted of 3 normal kidney transplant volunteers who underwent biopsy of kidney tissue (normal kidney control group), while 14 healthy children who underwent physical examination were collected as the normal control group. According to the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI), LN patients were divided into mild activity group ( n=8), moderate activity group ( n=9), and severe activity group ( n=15). According to the International Society of Nephrology/Society of Nephrology (ISN/RPS) 2003 LN classification criteria, pathological classification was performed (3 cases in the mild pathological damage group, 8 cases in the moderate pathological damage group, and 11 cases in the severe pathological damage group); Immunohistochemistry was used to detect the expression and distribution of IFN-α/β in glomeruli and renal interstitium; Enzyme linked immunosorbent assay (ELISA) was used to detect the concentration of IFN-α/β in serum samples and analyze its correlation with the pathological classification and disease activity of LN patients. Results:The serum and renal cortex IFN-α/β levels in the LN group were higher than those in the normal control group and normal kidney control group, respectively (all P<0.05). The average level of serum IFN-α/β in the heavy activity group was higher than that in the light and moderate activity groups (all P<0.05). The serum and renal cortex IFN-α/β levels in the severe pathological damage group were significantly higher than those in the mild and moderate pathological damage groups (all P<0.05). Conclusions:IFN-α/β in the renal cortex is closely related to renal injury in LN; Serum IFN-α/β can assist in evaluating the disease activity level of LN to a certain extent.

The 40 rats were randomly divided into sham group， model group， low， medium and high dosages of Danggui Shaoyaosan （12，24，36 g·kg^-1·d^-1） groups，observed the morphological changes of mitochondria in hippocampus of rats by electron microscopy after 14 days of continuous gavage. In situ end labeling（TUNEL） staining used to detect apoptosis and immunofluorescencereactive used to observe the expression of reactive oxygen species （ROS） and peroxisome proliferators-activated receptor γ coactivator lalpha （PGC-1α），quantitative Real-time polymerase chain reaction（Real-time PCR）detected the mRNA expression of dynamin-related protein 1 （Drp1），mitochondrial fusion protein 2 （MFN2） ，cytochrome C oxidase subunit Ⅳ （COX Ⅳ） and PGC-1α. Western blot detected the protein expression of adenosine 5'-monophosphate （AMP）-activated protein kinase （AMPK），phosphorylation（p）-AMPK，recombinant Sirtuin 1 （SIRT1） and PGC-1α. ResultCompared with the sham group，the results of model group showed that the damage of mitochondria in hippocampus was more obvious，accelerated the ROS production and apoptosis rate （P<0.01），decreased the mRNA level of MFN2，COX Ⅳ，PGC-1α，increased the mRNA level of Drp1，and descended the protein of p-AMPK/AMPK，SIRT1，PGC-1α （P<0.05，P<0.01）.Compared with the model group，the medium and high dose of DSS group notably improved the damage of mitochondria，reduced the production of ROS and apoptosis rate （P<0.01），promoted the mRNA expression of MFN2，COX Ⅳ，PGC-1α，inhibited the mRNA expression of Drp1，and up-regulated the protein of p-AMPK/AMPK，SIRT1，PGC-1α （P<0.01）. ResultDSS can significantly ameliorate the mitochondrial homeostasis imbalance in AD rats.

Objective:To evaluate the efficacy of Qinggan Bupi Jiangtang Decoction combined with western medicine in the treatment of adult type 2 diabetes mellitus (T2DM) with with liver hyperactivity and spleen deficiency syndrome.Methods:Prospective cohort study. A total of 103 T2DM patients with liver hyperactivity and spleen deficiency syndrome in the Department of endocrinology of Shanghai Municipal Hospital of Traditional Chinese Medicine from February 2020 to February 2021 were randomly divided into the observation group (52 cases) and the control group (51 cases) according to random number table method. Both groups were treated with conventional western medicine, the control group was treated with sitagliptin phosphate on the basis of routine treatment, and the observation group was treated with Qinggan Bupi Jiangtang Decoction on the basis of routine treatment. Both groups were treated for 12 weeks. TCM symptom scores were performed before and after treatment. The FPG, 2hPBG, HbA1c and fasting insulin (FINS) were detected by dry chemistry method and Roche electroluminescence method, and insulin resistance index (HOMA-IR) was calculated. The clinical efficacy was evaluated by dynamic blood glucose monitoring indexes TIR (percentage of time when glucose was in the range of 3.9-10.0 mmol/L), TAR (percentage of time when glucose was higher than the target range ≥ 11.1 mmol/L) and TBR (percentage of time when glucose was lower than the target range <3.9 mmol/L).Results:The total effective rate was 92.3% (48/52) in the observation group and 56.9% (29/51) in the control group ( χ2=15.32, P<0.01). The score of TCM syndrome in the observation group was significantly lower than that of the control group ( t=6.30, P<0.01). The compliance rate of HbA1c in the observation group was 46.2% (24/52) and that of the control group was 23.5% (12/51). There was significant difference between the two groups ( χ2=5.80, P=0.016). Compared with the groups before treatment, MAGE, TAR, TBR significantly decreased and TIR significantly increased in both groups after treatment ( P<0.01), but there was no significant difference between the two groups after treatment ( t values were 0.78, 1.06, 0.22 and 1.45, respectively, P>0.05). Compared with the groups before treatment, the levels of FPG, 2 hPBG and HbA1c in the two groups significantly decreased after treatment ( P<0.01), but there was no significant difference between the two groups after treatment ( t values were 1.32, 0.18,1.50, respectively, P>0.05). Compared with the groups before treatment, the levels of FINS and HOMA-IR in the two groups significantly decreased after treatment ( P<0.01), but there was no significant difference between the two groups after treatment ( t values were 1.25, 0.51, respectively, P>0.05). There were no adverse reactions in the observation group, 2 cases of mild nausea and 1 case of transient diarrhea in the control group. There was no significant difference between the two groups ( χ2=3.15, P=0.118). Conclusion:Qinggan Bupi Jiangtang Decoction combined with routine treatment can improve the blood glucose level, TIR and blood glucose standard rates of adult T2DM with liver hyperactivity and spleen deficiency syndrome, and the curative effect is equivalent to sitagliptin phosphate tablets.
