Immune checkpoint inhibitors (ICIs) are widely used in clinic, and the incidence of rare adverse events are increasing. The aim of this paper is to better define the rare adverse effect of diabetes mellitus associated with ICIs. We report 2 cases of diabetes mellitus associated with ICIs. Literature review was conducted and we discussed the clinical presentation, potential mechanisms and suggestions for optimal management. Two patients were both elderly women, case 1 had increased blood glucose after 7 months of using Durvalumab, and cases 2 had diabetic ketoacidosis after 6 weeks of using Pembrolizumab. Both patients were administered exogenous insulin to control blood glucose. Case 1 has been treated with Durvalumab until now and case 2 discontinued using of Pembrolizumab. HLA genotypes and other factors may explain the risk factors of diabetes associated with ICIs in some individuals. Diabetes mellitus associated with ICIs is an uncommon but potentially life-threatening endocrine system adverse event, which requires doctors to be vigilant. The patients who use ICIs need to monitor blood glucose. If they have hyperglycemia, endocrinologists should be asked to assist in diagnosis and treatment.

OBJECTIVE: To evaluate the effects of acupuncture on hypoglycaemic outcomes in type 2 diabetes mellitus (T2DM). METHODS: PubMed, Embase, Cochrane Library, and ClinicalTrials.gov were searched from inception up to July 2020, to identify randomised controlled trials (RCTs) that enrolled patients with T2DM and compared acupuncture combined with antidiabetic drugs to antidiabetic drugs alone. The primary outcomes were haemoglobin A_1c (HbA_1c) and fasting blood glucose (FBG). The secondary outcomes included 2-h blood glucose (2hBG), fasting insulin (FINS), homeostatic model assessment for insulin resistance (HOMA-IR), and acupuncture-related adverse events. Mean difference (MD) and 95% confidence interval (CI) were used as the effect measure in the meta-analysis. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation tool. RESULTS: Twenty-one RCTs (n=1,188) were included. The meta-analytic results showed that the acupuncture group had greater reductions in FBG (MD -6.46 mg/dL, 95% CI -11.95 to -0.98; moderate-quality evidence) and HOMA-IR (MD -1.23, 95% CI -2.16 to -0.31; low-quality evidence), but comparable changes in HbA_1c (MD -0.39%, 95% CI -0.84 to 1.61; very-low-quality evidence), 2hBG (MD -4.99 mg/dL, 95% CI -20.74 to 10.76; low-quality evidence), and FINS (MD -1.32 µIU/mL, 95% CI -3.76 to 1.12; low-quality evidence). No data on the incidence of diabetic complications were found. All acupuncture-related adverse events reported were mild. CONCLUSIONS The current evidence suggests that acupuncture, as a complementary therapy to antidiabetic drugs, has a small but statistically significant effect on decreasing FBG and improving insulin resistance. The effects of acupuncture on HbA_1c, 2hBG, and FINS remain uncertain. Acupuncture is generally safe in patients with mild diabetes. More evidence for the long-term effects of acupuncture on T2DM is needed. (Trial registration No. CRD42018115639).

To examine the efficacy and safety for metformin in treating antipsychotic-induced dyslipidemia.
 Methods: Two randomized placebo-controlled trials were included in the analysis. A total of 201 schizophrenia patients with dyslipidemia after treatment with an antipsychotic were collected, and the patients were divided into two groups: a 1 000 mg/d metformin group (n=103) and a placebo group (n=98). The clinical symptoms and metabolic indicators such as body weight, blood glucose, and blood lipids were assessed at baseline, the 12th week and the 24th week after treatment respectively.
 Results: After metformin treatment, the mean difference in the low-density lipoprotein cholesterol (LDL-C) value between the metformin group and the placebo group was from 0.16 mmol/L at baseline to -0.86 mmol/L at the end of the 24th week, which was decreased by 1.02 mmol/L 
(P<0.01). At the 24th week, the LDL-C was more than 3.37 mmol/L in 25.3% patients in the metformin group, which was significantly lower than that in the placebo group (64.8%) (P<0.01). Compared with the placebo group, there were significant changes in the weight, body mass index (BMI), insulin, insulin resistance index, total cholesterol and triglyceride, and high-density lipoprotein cholesterol (HDL-C) in the metformin group (all P<0.05). The treatment effects on weight and insulin resistance appeared at the 12th week and further improved at the 24th week, but the effects on improving dyslipidemia only significantly occurred at the end of the 24th week.
 Conclusion: The metformin treatment is effective in improving antipsychotic-induced dyslipidemia and insulin resistance, and the effect to reduce the antipsychotic-induced insulin resistance appears earlier than the effect to improve dyslipidemia.

OBJECTIVE: To investigate the intervention of curcumin and its analogue J7 on oxidative stress injury in testis of type 2 diabetic rats. METHODS: Sixty male SD rats, 10 rats were chosen as normal control group (NC), the other 50 rats were assigned to experiment group. Experiment diabetic rats were induced by high-fat food and intraperitoneal injection of steptozotocin (STZ). After the model was established successfully, diabetic rats were divided into four groups randomly: diabetes mellitus group (DM, n=12), curcumin treatment group (CUR, n=10), high dose treatment group of J7 (J+, n=10), low dose treatment group of J7 (J-, n=10). The CUR group were intragastrically administered with curcumin 20 mg/kg daily, in addition, the J+ group and the J- group were intragastrically administered with J7 20 mg/kg and 10 mg/kg daily respectively. After 8 weeks, the fast blood glucose was detected biochemically. The activity of superoxide dismutase (SOD) and the level of malondialdehyde (MDA) were detected by hydroxylamine method and thiobarbituric acid method respectively. The protein expressions of the nuclear factor-erythroid 2-related factor 2 (tNrf2), phosphorylation of Nrf2 (pNrf2), catalase (CAT), NAD(P)H quinine oxidoreductase 1 (NQO1) were measured by Western blot. The mRNA expressions of CAT, NQO1, hemeoxygenase-1 (HO1) were measured by quantitative real-time PCR (qRT-PCR). Morphological structure of testis was observed by hematoxylin-eosin (HE) staining. The expressions of Nrf2 and CAT were also detected by immunohistochemical method. RESULTS: The levels of fast blood glucose and MDA in DM group were increased significantly(P＜0.05), while the body weight, the activity of SOD, the protein expressions of pNrf2/tNrf2, CAT, NQO1 and the mRNA expressions of CAT, NQO1, HO1 were decreased (P＜0.05). Under light microscope, the DM group showed disrupted histological appearance. Immunohistochemistry showed that the protein expressions of Nrf2 around the nucleus and CAT were decreased. With the treatment of curcumin and J7, the MDA levels in the three treatment groups were decreased (P＜0.05). The activity of SOD, the protein expressions of pNrf2/tNrf2, CAT, NQO1 and the mRNA expressions of NQO1, HO1 were increased (P＜0.05). the levels of fast blood glucose were decreased in the J+ and J- group (P＜0.05), and the mRNA expression of CAT was increased in the J+ group (P＜0.05). The ratio of pNrf2/tNrf2 in the J+ group was significantly higher than that in CUR and J- group (P＜0.05). The protein level of CAT in the J+ group was also significantly higher than that in J- group (P＜0.05). There were no significant differences in other indexes among the three treatment groups. Under light microscope, the morphology was obviously improved in the three treatment groups. Immunohistochemistry showed that the protein expressions of Nrf2 around the nucleus and CAT were increased in the three treatment groups. It was suggested that high dose J7 had better antioxidant stress ability in testis of diabetic rats. CONCLUSION Curcumin and J7 could inhibit the oxidative stress damage of testicular tissue in diabetic rats, which might be related with the activation of the Nrf2-ARE signaling pathway.

INTRODUCTION: Epidural steroid injections are an integral part of nonsurgical management of radicular pain from lumbar spine disorders. We studied the effect of dexamethasone 8 mg epidural injections on the hypothalamic-pituitary-adrenal axis and serum glucose control of Asian patients. METHODS: 18 patients were recruited: six diabetics and 12 non-diabetics. Each patient received a total of dexamethasone 8 mg mixed with a local anaesthetic solution of lignocaine or bupivacaine, delivered into the epidural space. Levels of plasma cortisol, adrenocorticotropic hormone (ACTH), serum glucose after an overnight fast and two-hour postprandial glucose, as well as weight, body mass index, blood pressure and heart rate were measured within one week prior to the procedure (baseline) and at one, seven and 21 days after the procedure. RESULTS: Median fasting blood glucose levels were significantly higher on post-procedure Day 1 than at baseline. However, there was no significant change in median two-hour postprandial blood glucose from baseline levels. At seven and 21 days, there was no significant difference in fasting or two-hour postprandial glucose levels. Both ACTH and serum cortisol were significantly reduced on Day 1 compared to baseline in all patients. There was no significant difference in ACTH and serum cortisol levels from baseline at Days 7 and 21. CONCLUSION Our study shows that epidural steroid injections with dexamethasone have a real, albeit limited, side effect on glucose and cortisol homeostasis in an Asian population presenting with lower back pain or sciatica.

High-fat diets affect male reproduction and sexual function. Therefore, we evaluated the effects of prolonged resveratrol administration on the metabolic, sperm, and testicular parameters of rats fed a cafeteria diet. Male Wistar rats were divided at weaning into control (C, n = 20) and cafeteria (CAF, n = 16) groups. At 3 months, half of them were given daily supplementations of resveratrol (C-R, n = 10; CAF-R, n = 8) at a dosage of 30 mg kg^-1 body mass for 2 months. Animals were killed at 5 months of age, and blood, spermatozoa, and testes were collected for further analysis. Data were analyzed by one-way ANOVA, and P < 0.05 was considered statistically significant. The CAF diet promoted hyperglycemia (P < 0.0001), and treatment with resveratrol reversed this condition (P < 0.0001). The CAF diet reduced sperm viability and motility, while resveratrol improved these parameters (P < 0.05). Regarding testicular morphology, the height of the seminiferous epithelium was reduced in the CAF group compared with that of the C group (P = 0.0007). Spermatogenic cell proliferation was also reduced in the CAF group compared with that of the C group. However, the CAF-R showed an increase in cell proliferation rate compared with that of the untreated CAF group (P = 0.0024). Although it did not modify body mass, the consumption of a CAF diet promoted hyperglycemia, adverse testicular morphology remodeling, and abnormal sperm, which were attenuated by treatment with resveratrol, thus suggesting a protective effect of this antioxidant on spermatogenesis.

Baihu Jia Renshen Decoction recorded in Treatise on Febrile Diseases by Zhang Zhongjing in the Han Dynasty could be used to clear heat,invigorate Qi,and promote fluid production. The indications of Baihu Jia Renshen Decoction include infectious diseases,such as lung infection,influenza,encephalitis,enteric typhoid and hospital infection; thermoplegia; acute cerebrovascular disease,diabetes mellitus,severe hyperosmolarity,hypernatremia,intractable hypotension,shock and other internal diseases; sweating,irritation,thirst,want to drink several liters of water,dry mouth,dry tongue,and big pulse. This prescription has been widely used to treat acute and severe cases in the cardiovascular intensive care ward. The prescription can be used to treat exogenous and internal injury diseases,which are characterized by excessive heat,fluid injury,thirst for water,dry mouth,dry tongue and other symptoms; refractory hypotension and hypovolemic shock that need large dose of supplemental fluid to maintain blood pressure and may also belong to the extension of the Baihu Jia Renshen Decoction formula syndrome; severe hyperosmolarity and hypernatremia needing nasal feeding with large quantities of sterile water or cool boiled water that may also belong to the extension of the Baihu Jia Renshen Decoction formula syndrome; the four major symptoms,namely severe heat,excessive perspiration,great thirst,and large-bounding pulse,are actually the indications of Baihu Jia Renshen Decoction,rather than Baihu Decoction. Severe irritability should also be added into the indications of Baihu Jia Renshen Decoction; severe heat refers to pathogenesis,rather than a symptom.

Catalpol, a major bioactive component from Rehmannia glutinosa, which has been used to treat diabetes. The present study was designed to elucidate the anti-diabetic effect and mechanism of action for catalpol in db/db mice. The db/db mice were randomly divided into six groups (10/group) according to their blood glucose levels: db/db control, metformin (positive control), and four dose levels of catalpol treatment (25, 50, 100, and 200 mg·kg), and 10 db/m mice were used as the normal control. All the groups were administered orally for 8 weeks. The levels of fasting blood glucose (FBG), random blood glucose (RBG), glucose tolerance, insulin tolerance, and glycated serum protein (GSP) and the globe gene expression in liver tissues were analyzed. Our results showed that catalpol treatment obviously reduced water intake and food intake in a dose-dependent manner. Catalpol treatment also remarkably reduce fasting blood glucose (FBG) and random blood glucose (RBG) in a dose-dependent manner. The RBG-lowering effect of catalpol was better than that of metformin. Furthermore, catalpol significantly improved glucose tolerance and insulin tolerance via increasing insulin sensitivity. Catalpol treatment significantly decreased GSP level. The comparisons of gene expression in liver tissues among normal control mice, db/db mice and catalpol treated mice (200 and 100 mg·kg) indicated that there were significant increases in the expressions of 287 genes, whichwere mainly involved in lipid metabolism, response to stress, energy metabolism, and cellular processes, and significant decreases in the expressions of 520 genes, which were mainly involved in cell growth, death, immune system, and response to stress. Four genes expressed differentially were linked to glucose metabolism or insulin signaling pathways, including Irs1 (insulin receptor substrate 1), Idh2 (isocitrate dehydrogenase 2 (NADP), mitochondrial), G6pd2 (glucose-6-phosphate dehydrogenase 2), and SOCS3 (suppressor of cytokine signaling 3). In conclusion, catalpol ecerted significant hypoglycemic effect and remarkable therapeutic effect in db/db mice via modulating various gene expressions.

Diabetic nephropathy (DN) is one of the common microvascular complications of diabetes mellitus. Renal fibrosis is closely related to the deterioration of renal function. The present study aimed to investigate protective effect of Taxus chinensis on high-fat diet/streptozotocin-induced DN in rats and explore the underlying mechanism of action. The rat DN model was established via feeding high fat diet for 4 weeks and subsequently injecting streptozotocin (30 mg·kg body weight) intraperitoneally. The rats with blood glucose levels higher than 16.8 mmol·L were selected for experiments. The DN rats were treated with Taxus chinensis orally (0.32, 0.64, and 1.28 g·kg) once a day for 8 weeks. Taxus chinensis significantly improved the renal damage, which was indicated by the decreases in 24-h urinary albumin excretion rate, blood serum creatinine, and blood urea nitrogen. Histopathological examination confirmed the protective effect of Taxus chinensis. The thickness of glomerular basement membrane was reduced, and proliferation of mesangial cells and podocytes cells and increase in mesangial matrix were attenuated. Further experiments showed that Taxus chinensis treatment down-regulated the expression of TGF-β1 and α-SMA, inhibited phosphorylation of Smad2 and Smad3. These results demonstrated that Taxus chinensis alleviated renal injuries in DN rats, which may be associated with suppressing TGF-β1/Smad signaling pathway.
