We conducted a network meta-analysis (NMA) comparing DPP4i plus metformin (Met) combination with other Met-based oral antidiabetic drug (OAD) combinations used in treating patients with T2DM.Methods: We searched PubMed and Embase from inception until 19th April, 2022 for phase II and phase III trials in patients with T2DM on Met-based traditional OADs. The primary outcome was assessed by change in glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), and 2-hour post-prandial blood glucose (2h-PPG). The secondary safety outcomes assessed were hypoglycemic events, serious adverse events (SAEs), cardiovascular (CV) events, and gastrointestinal (GI) events.Results: Sixty-two trials were included in the analysis. The combination of DPP4i + Met revealed a comparable mean reduction in HbA1c levels to the glinides (Gli) + Met combination (mean difference [MD]: − 0.03%, 95% CI: 0.69, − 0.65), although the difference was not statistically significant. The mean HbA1c reduction with DPP4i + Met was greater than with sulfonylureas (SU) + Met (MD: − 0.05, 95% CI: − 0.29, 0.39), thiazolidinedione (TZD) + Met (MD: − 0.69, 95% CI: − 1.39, − 0.02), and SU + TZD (MD: 0.21; 95% CI: − 1.30, 1.71), with no statistical significance. DPP4i + Met demonstrated a non-significant lower incidence of CV events in comparison to TZD + Met (RR: 1.01, 95% CI: 0.46, 2.45) and SU + Met (RR: 1.06, 95% CI: 0.61, 2.06).Conclusion: DPP4i in combination with Met was efficacious and had a well-tolerated safety profile compared with other traditional OADs. This combination can be considered as a suitable treatment option for patients with T2DM.Keywords: dipeptidyl peptidase-4 inhibitors, efficacy, safety, metformin, type 2 diabetes mellitus

The barriers that prevent a GP from initiating insulin therapy may vary in comparison to those encountered by a diabetic patient; this aspect of clinical research in the South Shanghai metropolitan area has received limited attention so far.Objective: This is a 6-months of interventional analytic cohort study. The prime aim is to investigate the barriers general practitioners (GPs) face when initiating insulin therapy for patients with type 2 diabetes (T2D).Materials and Methods: As part of a training program, all 189 registered GPs in Nanhui Health Service Center in Shanghai were given a structured online-multi-choice questionnaire before and after a six-month interval, during which the GPs received sessions of training on insulin therapy either on theoretic classes or clinical practices.Results: Before and after training, via the methods of multiple-response analyses, the results showed that social, GP’s, and patient barriers to initiating insulin therapy were comparable. However, through the crosstabs chi-square test, we found significant changes in the basal insulin initiation following the prescription of the senior endocrinologists, the titration of insulin, and the need for training (p< 0.05). The Spearman analyses discovered significant changes associated with the cause of initial insulin refusal and the factors influencing insulin administration. Finally, the binary logistic regression analysis revealed that distinct causes such as social factors, insurance, GP experience, insulin dosage calculation, follow-up, and patients’ feelings are related to insulin treatment application before and after training.Conclusion: According to this study, training increased general practitioners’ confidence in initiating insulin administration, especially basal insulin. General practitioners require additional education on insulin therapy, with a potential need for increased face-to-face training for insulin initiation.Keywords: diabetes mellitus, insulin initiation barrier, general practitioner, community

We hypothesized that fatty oil nanoparticles (OIL-NPs) could overcome this limitation. The protective effect of OIL-NPs against monocrotaline-induced lung injury in rats was studied.Methods: We prepared OIL-NPs by wrapping fatty oil with polylactic-polyglycolide nanoparticles (PLGA-NPs) and conducted in vivo and in vitro experiments to explore its anti-pulmonary hypertension (PH) effect. In vitro, we induced malignant proliferation of pulmonary artery smooth muscle cells (RPASMC) using anoxic chambers, and studied the effects of OIL-NPs on the malignant proliferation of RPASMC cells and phospholipase C (PLC)/inositol triphosphate receptor (IP3R)/Ca2+ signal pathways. In vivo, we used small animal echocardiography, flow cytometry, immunohistochemistry, western blotting (WB), polymerase chain reaction (PCR) and metabolomics to explore the effects of OIL-NPs on the heart and lung pathological damage and PLC/IP3R/Ca2+ signal pathway of pulmonary hypertension rats.Results: We prepared fatty into OIL-NPs. In vitro, OIL-NPs could improve the mitochondrial function and inhibit the malignant proliferation of RPASMC cells by inhibiting the PLC/IP3R/Ca2+signal pathway. In vivo, OIL-NPs could reduce the pulmonary artery pressure of rats and alleviate the pathological injury and inflammatory reaction of heart and lung by inhibiting the PLC/IP3R/Ca2+ signal pathway.Conclusion: OIL-NPs have anti-pulmonary hypertension effect, and the mechanism may be related to the inhibition of PLC/IP3R/Ca2+signal pathway.

A total of 588 patients on peritoneal dialysis were randomly selected from 6 regions in Fujian Province in southern China using a stratified cluster sampling method.Results: The mean age of the patients were 56.5 ± 14.73 years. In the univariate analysis, knowledge, user experience and family support were the factors that affected patients’ choice of APD (all P < 0.05) and were positively correlated with the treatment utilization rate. In the multivariate analysis, 3 factors (treatment with APD, knowledge of APD, and family support) remained significantly associated not choosing APD. The selection rate for APD was 2.594 times higher among patients who had received APD than among patients who had never received APD. The selection rate for patients with “a lot of knowledge” about APD was 10.75 times that of patients with “no knowledge”.Conclusion: Patients’ knowledge of APD, experience in application and family support were the main factors affecting the choice of APD as a treatment mode (P < 0.05) and were positively correlated with the treatment utilization rate. Further studies are needed to improve the APD treatment completion rates by modulation the above-mentioned factors.Relevance to Clinical Practice: This study provides scientific evidence for improving APD treatment completion rates and improving patient quality of life.Keywords: peritoneal dialysis, APD, dialysis mode, influencing factors, follow up, end-stage kidney disease

There is currently no consensus regarding the diagnosis of SAPHO syndrome, and specific treatments are empirical because of its rarity.Case Presentation: A 62-year-old woman was referred to our department with complaints of low back and lower extremity pain for 2 years, 1.5 years after lumbar spine surgery, and recurrent low back pain for 1 year. Laboratory test results revealed elevated hs-CRP levels and erythrocyte sedimentation rate. Combined with her surgical history and lumbar CT results, adjacent segment degeneration (ASD) was first considered. NSAIDs, analgesics, and supplemental therapies were also administered. However, the patient’s symptoms were not significantly relieved. During re-examination, hyperkeratosis with active pustulosis was observed on the patient’s palms. Osteitis of the left sacroiliac joint was revealed on imaging. Skeletal ECT revealed a typical “horn sign”. The patient was diagnosed with SAPHO syndrome. Based on the original treatment, sulfasalazine enteric-coated tablets, adalimumab (a biological agent of TNF-α), pregabalin, and tramadol sustained-release tablets were administered. The patient reported that her pain was significantly relieved. He was discharged from the hospital and received adalimumab treatment (40 mg once per fortnight in the first 6 months and 40 mg once per month after month 6) in the outpatient clinic. The hyperkeratosis with active pustulosis on both palms fully recovered after 12 months of treatment. The patient was followed up 6 months after full recovery, and no recurrence was found in the symptoms of low back and lower extremity pain and palmar hyperkeratosis with active pustulosis.Conclusion: SAPHO syndrome should be suspected in patients present with osteoarticular and/or dermatological manifestations. Biological agents can be used to treat patients with refractory SAPHO syndrome.Keywords: SAPHO syndrome, low back pain, osteitis, pustulosis, adalimumab

We postulated that pseudoephedrine nanoparticles (PSE-NPs) with high bioavailability could overcome this limitation. The defensive function of PSE-NPs nanoparticles against adriamycin-induced reproductive toxicity in mice was studied.Methods: We encapsulated PSE in polylactide-polyglycolide nanoparticles (PLGA-NPs) and verified their protective activity against testicular injury in vivo and in vitro.Results: We report a promising delivery system that loads PSE into PLGA-NPs and finally assembles it into a nanocomposite particle. In vitro, PSE-NPs reduced the adriamycin-induced apoptosis of GC-1 cells significantly, improved mitochondrial energy metabolism and promoted expression of the proteins related to the gonadotropin-releasing hormone (GnRh) receptor signaling pathway. In vivo, evaluation of sperm indices and histology showed that adriamycin could induce testicular toxicity. PSE-NPs significantly increased the sperm motility of mice, reduced the percent apoptosis and oxidative stress of testes, increased serum levels of GnRh, activated the GnRhR signaling pathway in testes and promoted expression of meiosis-related factors.Conclusion: In view of their safety and efficiency, these PSE-NPs have potential applications in alleviating adriamycin-induced reproductive toxicity.Graphical Abstract: Keywords: pseudoephedrine nanoparticles, adriamycin, reproductive toxicity, GnRhR signaling pathway, sperm meiosis

Here, we aimed to further investigate whether CpG-ODN exerts such effect via regulating endoplasmic reticulum (ER) stress and revealed the underlying mechanism.Methods: Five-week-old C57BL/6 mice were randomly grouped and treated with or without CpG-ODN or/and SP600125. Meantime, RAW264.7 cells were used to investigate the effect of CpG-ODN on OVA-induced ER stress in vitro. The cellularity of bronchoalveolar lavage fluid (BALF) was classified and counted after Wright–Giemsa staining. HE and PAS staining methods were applied to analyze airway inflammation. The protein levels of IL-4, IL-5, IL-13, p-JNK, JNK, CHOP, XBP1, ATF6α and GRP78 in lung tissues were detected by Western blotting. Correspondingly, the ER stress markers were detected by Western blotting and immunofluorescence in RAW264.7 cells.Results: In OVA-induced allergic airway inflammation, CpG-ODN significantly suppressed inflammatory cells infiltration, goblet cell hyperplasia and the protein expression of Th2 cytokines. Moreover, OVA exposure strongly increased the activation of ER stress with higher protein expressions of CHOP, XBP1, ATF6α and GRP78. However, these OVA-induced increase of ER stress markers were markedly suppressed by CpG-ODN treatment. In addition, exposure to OVA significantly increased the phosphorylation of JNK, which was significantly reduced by CpG-ODN treatment. Remarkably, single treatment of SP600125, an antagonist of JNK, functioned similarly as CpG-ODN in mitigating allergic airway inflammation and suppressing OVA-induced activation of ER stress; however, no significant synergistic effect was evidenced by combined treatment of SP600125 and CpG-ODN. Furthermore, in OVA-stimulated RAW264.7 cells, we also found that OVA stimulation increased the expressions of ER stress markers, and CpG-ODN significantly reduced their expression levels via suppressing the phosphorylation of JNK.Conclusion: These results indicated that CpG-ODN mitigates allergic airway inflammation via suppressing the activation of JNK-medicated ER stress.Keywords: asthma, CpG-ODN, SP600125, endoplasmic reticulum homeostasis

ODLs were recruited from January 12, 2017 to June 27, 2018. The independent sample t-test and grounded theory coding method were employed for data analysis.Results: Of the 125 participants who returned valid questionnaires, 18 were included in the in-depth interviews. ODLs’ quality of life was associated with the following health-related perceptions: “life barriers”, “subjective health status”, and “treatment outcomes” across the domains of physiology, psychology, social relations, and environment.Conclusion: Our findings indicate that ODLs’ quality of life is associated with their health-related perceptions. Thus, to improve older adults’ quality of life, more attention should be paid to enhancing non-medical factors such as their health-related perceptions.Keywords: life barriers, subjective health status, treatment outcomes

But, the synergistical effect of visceral fat along with skeletal muscle on the risk of cardiovascular diseases (CVD) in T2DM still remains controversial. Thus, we investigated the relationship between skeletal muscle mass to visceral fat area ratio (SVR) and 10-yr CVD risk scores.Patients and Methods: A total of 291 T2DM patients aged 40– 80 years were enrolled in the current study. SVR was evaluated based on bioelectrical impedance measurements. Both Framingham risk score system and China-PAR risk model were applied to estimate future 10-yr CVD risk in T2DM population.Results: The 10-yr CVD risk scores increased with the decreased SVR tertiles in T2DM (All P< 0.001). SVR value was obviously lower in the high-risk group than that of low- or moderate-risk group (All P< 0.05). However, no significant differences were observed in BMI among different CVD risk groups. Besides, SVR was correlated with Framingham risk score (r=− 0.408; P< 0.001) and China-PAR risk score (r=− 0.336; P< 0.001). HOMA-IR, triglycerides and blood pressure were also inversely related to SVR (All P< 0.05). Furthermore, SVR value was independently correlated with both Framingham 10-yr CVD risk score (β=− 0.074, P=0.047) and China-PAR risk score (β=− 0.100, P=0.004) after adjustment for confounding factors, including age, gender, BMI, FPG, HbA1c, diabetes duration, albumin, creatinine, uric acid, smoking, blood pressure and blood lipid. The linear regression analysis was also conducted for men and women, respectively, indicating that the negative relationship between SVR and 10-yr CVD risk was observed in men but not in women.Conclusion: T2DM populations who have lower SVR value are more likely to increase CVD risk. SVR levels show marked and inverse correlation with estimated 10-yr CVD risk in T2DM, indicating that SVR could be a valuable parameter to assess the risk of CVD events in clinical practice, especially in men.Keywords: type 2 diabetes mellitus, cardiovascular diseases, skeletal muscle mass to visceral fat area ratio, risk assessment

NLR family pyrin domain-containing 3 (NLRP3) inflammasome activation has been implicated in PD in postmortem human PD brains, indicating it as a potential target for PD treatment. Melatonin, a multitasking molecule, has been found to have anti-inflammatory activities, mediated by silence information regulator 1 (SIRT1). However, whether and how melatonin is involved in inflammasome-induced neuroinflammation in PD pathogenesis remains unclear.Methods: We investigated the potential anti-inflammatory effects of melatonin in vitro and in vivo, using 1-methyl-4-phenylpyridinium (MPP+)-simulated BV2 and primary microglia cell models, and a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced murine PD model, with or without melatonin treatment. Rotarod, grip strength, and open-field tests were performed to measure the effects of melatonin on MPTP-induced motor disorders. Degeneration of dopaminergic neurons was evaluated by immunofluorescence. Changes in microglia were examined by immunofluorescence and Western blotting, and the expression levels of the involved signaling molecules were assessed by Western blotting and enzyme-linked immunosorbent assay (ELISA). Intracellular reactive oxygen species (ROS) was detected using fluorescent probes via flow cytometry.Results: We found that melatonin significantly alleviated motor dysfunction and prevented MPTP-induced neurotoxicity in dopaminergic neurons. Additionally, melatonin reduced MPTP-induced microglial activation and suppressed NLRP3 inflammasome activity, and also inhibited IL-1β secretion. Moreover, in MPP+-primed BV2 cells, melatonin markedly restored the downregulation of SIRT1 and attenuated the activation of the NLRP3 inflammasome. This was reversed by SIRT1 inhibitor treatment.Conclusion: In conclusion, our data demonstrated that melatonin attenuates neuroinflammation by negatively regulating NLRP3 inflammasome activation via a SIRT1-dependent pathway in MPTP-induced PD models. These findings provide novel insights into the mechanism underlying the anti-inflammatory effects of melatonin in PD.Keywords: inflammasomes, melatonin, NLRP3, Parkinson disease, sirtuin 1

Many inflammatory markers in peripheral blood are proved to be associated with stroke severity or prognosis. But few comprehensive models or scales to evaluate the post-stroke depression (PSD) have been reported. In this study, we aimed to compare the level of systemic inflammation markers between PSD and non-PSD patients and explore the association of these inflammatory markers with PSD.Methods: Totally, 432 ischemic stroke patients were consecutively enrolled in the study and received 1 month follow-up. We used the 17-Hamilton Rating Scale to measure depressive symptoms at 1 month after stroke. With the Hamilton Depression Scale score of > 7, patients were diagnosed with PSD. Systemic immune-inflammation index (SII), neutrophil-to-lymphocyte (NLR), platelet-to-lymphocyte (PLR) and derived neutrophil-to-lymphocyte ratio (dNLR) were calculated from the admission blood work.Results: Finally, 129 patients (30.5%) were diagnosed with PSD at 1 month. PSD patients showed significantly higher levels of SII (501.27 (345.43– 782.58) vs 429.60 (315.64– 570.98), P=0.001), NLR (2.36 (1.77– 3.82) vs 2.17 (1.56– 2.80), P=0.010), dNLR (1.67 (1.30– 2.51) vs 1.54 (1.16– 1.99), P=0.009), PLR (124.65 (95.25– 155.15) vs 109.22 (92.38– 142.03), P=0.015), especially SII at admission as compared to non-PSD patients. In the logistic analysis, SII value (> 547.30) was independently associated with the occurrence of PSD (OR=2.181, 95% CI=1.274– 3.732, p =0.004), better than dNLR (OR=1.833, 95% CI=1.071– 3.137, p =0.027), PLR (OR= 1.822, 95% CI=1.063– 3.122, p =0.029) and NLR (OR =1.728, 95% CI=1.009– 2.958, p =0.046).Conclusion: Increased SII, PLR, dNLR, NLR, particularly SII at admission, are significantly correlated with PSD and may add some prognostic clues to find early discovery of PSD.Keywords: inflammatory markers, post-stroke depression, systemic immune-inflammation index, neutrophil-to-lymphocyte, platelet-to-lymphocyte, derived neutrophil-to-lymphocyte ratio

The rapid release of thyroid hormones following RAI may on occasion trigger severe events, such as thyroid storm or heart block. This study presents two cases of possible acute adrenocortical insufficiency precipitated by radioiodine therapy.Case Presentation: Two females aged 65 and 19 years with long-standing Graves’ disease underwent radioiodine treatment at our clinical center. Both patients suffered nausea, fatigue, aggravated palpitation, and relative hypotension thereafter. Laboratory data showed severe thyrotoxicosis with free thyroxine higher than three times the upper limit, while basal serum cortisol (8 AM) was below the lower limit (5.08 μg/dL and 2.08 μg/dL respectively) under stress, indicating a potential relative adrenocortical insufficiency. There was then full recovery after adequate hydrocortisone therapy. As thyrotoxicosis resolved, the levels of basal cortisol were subsequently raised to normal.Conclusion: Post-RAI adrenocortical insufficiency might occur in patients with severe Graves’ disease. Basal serum cortisol might be a cost-effective parameter for the identification of potential patients.Keywords: Graves’ disease, hyperthyroidism, adrenal insufficiency, radioiodine therapy

Stress hyperglycemia is frequent in patients with acute illness such as stroke. We aimed to explore the association between stress hyperglycemia and HT in AIS patients.Methods: A total of 287 consecutive participants with HT and 285 age- and sex-matched stroke patients without HT were enrolled in this study. Baseline glucose and glycated hemoglobin (HbA1c) levels were collected to measure stress hyperglycemia. The stress hyperglycemia ratio (SHR) was calculated by dividing the fasting plasma glucose at admission with HbA1c. HT was diagnosed by follow-up imaging assessment, and was radiologically classified as hemorrhagic infarction type (HI) 1 or 2 or parenchymal hematoma type (PH) 1 or 2.Results: Univariate analysis showed that SHR is significantly higher among patients with HT than those without HT. Compared to the patients in the lower three quartiles of SHR, the incidence of HT was significantly higher among patients with the highest quartile of SHR in total population, diabetic and non-diabetic population. We also observed that patients with the highest SHR quartile were associated with an increased risk of hemorrhagic transformation after adjusted for potential covariates (68.4% versus 39.1%; adjusted odds ratio, 2.320; 95% confidence interval, 1.207– 4.459; P=0.012).Conclusion: The stress hyperglycemia ratio, representing the state of stress hyperglycemia, was significantly associated with an increased risk of hemorrhagic transformation in patients with acute ischemic stroke.Keywords: hyperglycemia, hemorrhagic transformation, acute ischemic stroke, stress hyperglycemia

The physical properties of liquid alloy are crucial for many science fields. However, acquiring these properties remains challenging. By means of the deep neural network (DNN), here we presented a deep learning interatomic potential for the Ti–Ni–Cr–Al liquid system. Meanwhile, the thermophysical properties of the Ti–Ni–Cr–Al liquid alloy were experimentally measured by electrostatic levitation and electromagnetic levitation technologies. The DNN potential predicted this liquid system accurately in terms of both atomic structures and thermophysical properties, and the results were in agreement with the ab initio molecular dynamics calculation and the experimental values. A further study on local structure carried out by Voronoi polyhedron analysis showed that the cluster exhibited a tendency to transform into high-coordinated cluster with a decrease in the temperature, indicating the enhancement of local structure stability. This eventually contributed to the linear increase in the density and surface tension, and the exponential variation in the viscosity and the diffusion coefficient with the rise of undercooling.

Secondly, we analyzed serum HER2 levels in breast cancer patients with different metastatic degrees.Results: There is a higher correlation between serum HER2 and tissue HER2 in breast cancer patients with stage III (κ=0.670, p< 0.001) and stage IV (κ=0.464, p< 0.001). Serum HER2 levels were significantly associated with imaging results (κ=0.478, p< 0.001). The ROC curve analysis showed that serum HER2 was superior to other serum markers for predicting metastatic breast cancer. Multinomial logistic regression revealed that the patients with higher serum HER2 levels would be more likely to have breast cancer metastasis.Conclusion: Serum HER2 levels in breast cancer patients can partly reflect tissue HER2 expression and tumor imaging changes, and serum HER2 may be used as a biomarker for evaluating metastatic status in patients with breast cancer.Keywords: serum HER2, breast cancer, tumor metastasis, biomarker

Impaired kidney function has been associated with depression in non-stroke subjects. We would like to evaluate whether the estimated glomerular filtration rate (eGFR) on admission is associated with the development of PSD.Patients and methods: Total of 268 patients with acute ischemic stroke were recruited and completed 1-month follow-up visit. eGFR was calculated from the serum creatinine value, race, age, and sex by using the chronic kidney disease epidemiology collaboration equation (CKD-EPI creatinine equation). The 17-item Hamilton Depression Scale was used to evaluate depression symptoms. Patients with a depression score of ≥ 7 were evaluated using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, 4th edition, for diagnosing post-stroke depression at 1 month. Meanwhile, 114 normal control subjects were also recruited.Results: Ninety-three (34.7%) patients were diagnosed as having PSD at 1 month. There was a significant intergroup difference in eGFR levels within 24 hrs after admission (F=13.608, p< 0.001). The levels of eGFR within 24 hrs after admission were significantly lower in both non-PSD patients and PSD patients than in normal controls. In logistic regression, the level of eGFR (< 82mL/min/1.73m 2) was independently associated with increased risk of PSD even after adjusting for confounders (OR=2.328, 95% CI:1.092– 4.965, p=0.029).Conclusion: Reduced eGFR was found to be correlated with the development of PSD and it suggests the need for greater attentions and potential interventions for depression in patients with stroke and with reduced eGFR.Keywords: estimated glomerular filtration rate, eGFR, post-stroke depression, stroke, Depression
