OBJECTIVE: To evaluate the clinical efficacy and safety of Wuziyuye Decoction in the treatment of type-II diabetes mellitus (DM) with qi-yin deficiency complicated by asthenospermia. METHODS: We selected 100 cases of type-II DM with qi-yin deficiency complicated by asthenospermia treated in the First Hospital Affiliated to Ningbo University from January 2023 to March 2024, and randomly assigned them to receive Wuziyuye Decoction (the trial group, n = 50) and oral L-carnitine solution (the control group, n = 50) in addition to Western medicine to reduce fasting blood glucose to normal in both groups. After 12 weeks of medication, we followed up the patients for 24 weeks, obtained their semen parameters, traditional Chinese medicine (TCM) syndrome scores and levels of reproductive hormones, and the clinical pregnancy outcomes of their partners, followed by comparison of the data collected between the two groups before and after treatment. RESULTS: After 12 weeks of treatment, the trial group showed significant improvement over the baseline in the percentage of progressive motility (PR%) (［35.5±6.1］% vs ［18.0±4.2］%, P<0.05), sperm concentration (［54.0±33.4］ vs ［40.0±36.1］ × 10⁶/ml, P<0.05), and TCM syndrome score (4.5±2.3 vs 18.5±5.2, P<0.05), but no statistically significant difference in the semen volume (［2.85±0.36］ vs ［2.84±0.59］ ml, P>0.05), while the controls exhibited markedly improved percentage of PR% (［29.5±6.2］% vs ［18.5±4.5］%, P<0.05) and sperm concentration (［45.0±34.1］ vs ［42.0±38.3］ × 10⁶/ml, P<0.05), but no statistically significant difference in the semen volume (［3.04±0.89］ vs ［2.90±0.78］ ml, P>0.05) and TCM syndrome score (17.2±4.5 vs 17.8±4.8, P>0.05). The patients treated with Wuziyuye Decoction achieved even more significant improvement than the controls in the percentage of PR%, sperm concentration and TCM syndrome score (P<0.05), but there were no statistically significant differences in the reproductive hormone levels and clinical pregnancy outcomes between the two groups of patients after treatment (P>0.05). And no severe adverse reactions were observed in either group. CONCLUSION Wuziyuye Decoction is safe and effective for the treatment of type-II DM with qi-yin deficiency complicated by asthenospermia by improving the sperm motility and concentration of the patient.

OBJECTIVE: To explore the association between the use of metformin and the risk of ischemic stroke in patients with type 2 diabetes. METHODS: A prospective cohort study was designed from the Fangshan family cohort in Beijing. According to metformin use at baseline, 2 625 patients with type 2 diabetes in Fangshan, Beijing were divided into metformin group or non-metformin group and the incidence of ischemic stroke between the different groups during follow-up was estimated and compared by Cox proportional hazard regression model. The participants with metformin were first compared with all the parti-cipants who did not use metformin, and then were further compared with those who did not use hypoglycemic agents and those who used other hypoglycemic agents. RESULTS: The patients with type 2 diabetes were with an average age of (59.5±8.7) years, and 41.9% of them were male. The median follow-up time was 4.5 years. A total of 84 patients developed ischemic stroke during follow-up, with a crude incidence of 6.4 (95%CI: 5.0-7.7) per 1 000 person-years. Among all the participants, 1 149 (43.8%) took metformin, 1 476 (56.2%) were metformin non-users, including 593 (22.6%) used other hypoglycemic agents, and 883 (33.6%) did not use any hypoglycemic agents. Compared with metformin non-users, the Hazard ratio (HR) for ischemic stroke in metformin users was 0.58 (95%CI: 0.36-0.93; P = 0.024). Compared with other hypoglycemic agents, HR was 0.48 (95%CI: 0.28-0.84; P < 0.01); Compared with the group without hypoglycemic agents, HR was 0.65 (95%CI: 0.37-1.13; P=0.13). The association between metformin and ischemic stroke was statistically significant in the patients ≥ 60 years old compared with all the metformin non-users and those who used other hypoglycemic agents (HR: 0.48, 95%CI: 0.25-0.92; P < 0.05). Metformin use was associated with a lower incidence of ischemic stroke in the patients with good glycemic control (0.32, 95%CI: 0.13-0.77; P < 0.05). In the patients with poor glycemic control, and the association was not statistically significant (HR: 0.97, 95%CI: 0.53-1.79; P>0.05). There was an interaction between glycemic control and metformin use on incidence of ischemic stroke (P_interaction < 0.05). The results of the sensitivity analysis were consistent with the results in the main analysis. CONCLUSION Among patients with type 2 diabetic in rural areas of northern China, metformin use was associated with lower incidence of ischemic stroke, especially in patients older than 60 years. There was an interaction between glycemic control and metformin use in the incidence of ischemic stroke.

BACKGROUND: Preliminary studies have indicated that Shexiang Baoxin Pill (MUSKARDIA) has a coronary artery dilation effect and increases the coronary blood flow, relieving the symptoms of angina. This study aimed to evaluate the benefit of MUSKARDIA on patients with stable coronary artery disease (CAD) and diabetes mellitus (DM). METHODS: This was a subgroup analysis of a multicenter, randomized, placebo-controlled phase IV trial. CAD patients with a medical history of DM or baseline fasting blood glucose (FBG) ≥7.0 mmol/L were grouped according to the treatment (standard therapy plus MUSKARDIA or placebo). The primary outcome was major adverse cardiovascular events (MACEs), which was the composite outcome of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. The secondary outcome was the composite outcome of all-cause death, non-fatal myocardial infarction, non-fatal stroke, hospitalization for unstable angina or heart failure, and coronary angioplasty. RESULTS: MACEs occurred in 2.6% (9/340) and 4.8% (18/376) of patients in the MUSKARDIA and placebo groups, respectively ( P  = 0.192). Secondary composite outcome was significantly less frequent with MUSKARDIA than with placebo (15.3% [52/340] vs . 22.6% [85/376], P  = 0.017). Risk of MACEs (hazard ratio [HR] = 0.69, 95% confidence interval [CI]: 0.31-1.57) was comparable between two groups. In patients with uncontrolled DM (≥4 measurements of FBG ≥7 mmol/L in five times of follow-up), the risk of secondary outcome was significantly lower with MUSKARDIA (5/83, 6.0%) than with placebo (15/91, 16.5%) (HR = 0.35, 95%CI: 0.13-0.95). CONCLUSION: As an add-on to standard therapy, MUSKARDIA shows a trend of reduced MACEs in patients with stable CAD and DM. Furthermore, MUSKARDIA may reduce the frequency of all-cause death, hospitalization, and coronary angioplasty in this population, especially in those with uncontrolled DM.

OBJECTIVE: The main aim of this study is to investigate whether acupuncture could be an effective complementary treatment for reducing the risk of macrovascular complications in diabetic patients currently taking antidiabetic medications using a nationwide population-based database. METHODS: We conducted a retrospective cohort study to assess the efficacy of acupuncture on cardiovascular complications in diabetic patients using data from patients between 40 and 79 years of age, newly diagnosed with diabetes between 2003 and 2006, found in the National Health Insurance Service-National Sample Cohort (NHIS-NSC) in Korea. From the data, we identified 21,232 diabetic patients who were taking antidiabetic medication between 2003 and 2006. The selected patients were divided into two groups-those who received acupuncture at least three times and those who received no acupuncture (non-acupuncture) in the year following their diagnosis of diabetes. After 1:1 propensity score matching (PSM), each group had 3350 patients, and the observation ceased at the occurrence of a major adverse cardiovascular event (MACE), which was defined as either myocardial infarction, stroke, or death due to cardiovascular cause. RESULTS: After PSM, the acupuncture group had a lower incidence of MACE (hazard ratio [HR]: 0.87; 95% confidence interval [CI]: 0.81-0.94; P = 0.0003) and all-cause mortality (HR: 0.77; 95% CI: 0.70-0.84; P < 0.0001) than the non-acupuncture group; the HRs for stroke-related mortality (HR: 0.75; 95% CI: 0.56-1.00; P = 0.0485), ischemic heart disease mortality (HR: 0.53; 95% CI: 0.34-0.84; P = 0.006) and circulatory system disease mortality (HR: 0.67; 95% CI: 0.55-0.82; P < 0.0001) were lower in the acupuncture group than in the non-acupuncture group in the secondary analysis. CONCLUSION Our results indicate that diabetic patients receiving acupuncture treatment might have a lower risk of MACE, all-cause mortality and cardiovascular mortality. This population-based retrospective study suggests beneficial effects of acupuncture in preventing macrovascular complications associated with diabetes. These findings call for further prospective cohort or experimental studies on acupuncture treatment for cardiovascular complications of diabetes.

Type 2 diabetes mellitus is a progressive process. With the course of the disease progress, microvascular and macrovascular complications always happen. Thrombotic events caused by macrovascular complications, including coronary heart diseases and cerebrovascular diseases, are the main fatal factor for the patients with type 2 diabetes. Endothelial dysfunction, coagulative activation, impaired fibrinolysis, together with hyper-reactive platelets contribute to the diabetic prothrombotic state, which is strongly related to the macrovascular complications. In particular, the hyper-reactive platelets play a fundamental role among them. Type 2 diabetes is characterized by several metabolic dysfunctions such as hyperglycemia, insulin resistance and shortage, oxidative stress, systemic inflammation, obesity, and dyslipidemia. These metabolic dysfunctions work together to promote the formation of hyper-reactive platelets, which are distinctive in type 2 diabetes. The regular antiplatelet drugs, like aspirin, show limited inhibitory effect on them. Hence, studying the mechanism behind the hyper-reactive platelets could provide a brand-new view on the prevention of macrovascular complications and cardiovascular events in type 2 diabetes.

OBJECTIVE: To observe the effects of AdipoRon orally on the functions of spleen and pancreas in type 2 diabetic mice, in order to present data for clinical application. METHODS: Forty C57/BL6 male mice were randomly divided into 2 groups: normal control group (n=10) and model group (n=30), the former group was fed normally, while the later group was fed with high fat and sugar for 4 weeks.After that, type 2 diabetes model was established in DM group induced by intraperitoneal injection of streptozotocin (STZ, 40 mg/kg).As type 2 diabetes model established successfully, the model mice were randomly divided into three groups (n=10): diabetes mellitus (DM) group, high dose of AdipoRon group (DM + H) and low dose of adiponRon group (DM + L).All the four groups were treated with saline, saline, AdipoRon at the doses of 20 mg/kg and 50 mg/kg by gavages respectively, once a day for 10 days.And then put them to death for collecting blood, pancreas and spleen.Pathological changes of pancreas were observed with a light microscope after HE staining.Protein contents of insulin receptor (INSR), insulin receptor substrate 1( IRS-1) and tumor necrosis factor-α(TNF-α) in pancreatic and spleen tissues were detected by ELISA.The protein level of phosphorylation insulin receptor substrate 1(p-IRS-1) in pancreas was determined by Western blot, and the expression of insulin mRNA in pancreas was tested by RT-PCR. RESULTS: Under the light microscope, it was visible that the pancreatic tissue in NC group was full and closely packed, and the islet was big.Pancreatic tissue of DM mice was incompact and the islet of DM mice was smaller than that of normal mice.As for the mice treated with AdipoRon orally, the pancreatic tissue was full and closely arranged, and the islet was slightly smaller.Compared with NC group, the levels of TNF-α in pancreas and spleen of DM group were increased markedly, the levels of INSR and IRS-1 were decreased, the spleen coefficient, p-IR-1 protein level and insulin mRNA expression in pancreas were decreased, all were significant statistically (P＜0.05).Compared with DM group, the levels of TNF-α in pancreas and spleen of AdipoRon groups were decreased, the levels of INSR and IRS-1 in pancreas and spleen of AdipoRon groups were increased, while the spleen coefficient was increased (P＜0.05).The p-IRS-1 protein level and insulin mRNA expression in pancreas in DM+H group were increased (P＜0.05).Compared with DM + L group, the level of TNF-α was decreased, and the levels of INSR and IRS-1 were significantly increased (P＜0.05) in DM + H group (P＜0.05). CONCLUSION Oral administration of AdipoRon can protect the spleen and pancreas of diabetic mice by decreasing the inflammatory response, up-regulating the expression of INSR, and increasing p-IRS-1 level in diabetic mice.

BACKGROUND: Microvascular complications in type 2 diabetes (T2DM), including diabatic retinopathy (DR), diabetic kidney disease (DKD), diabetic peripheral neuropathy (DPN) are the leading causes of visual loss, end-stage renal disease or amputation, while the current therapies are still unsatisfactory. Chinese medicine (CM) has been widely used for treating diabetic mellitus. However, most of the previous studies focused on the single complication. The role of CM treatment in T2DM patients with 2 or multiple microvascular complications is not clear. OBJECTIVE: To appraise the curative effect of CM in T2DM patients with 2 or multiple microvascular complications, and to compare the effects of stationary treatment and individualized treatment in T2DM patients with microvascular complications. METHODS: This trial will be an 8-center, randomized, controlled study with 8 parallel groups. A total of 432 patients will be randomized to 8 groups: DR study group (32 cases) and a corresponding control group (32 cases), DR+DKD study group (64 cases) and a corresponding control group (64 cases), DR+DPN study group (64 cases) and a corresponding control group (64 cases), DR+DKD+DPN study group (56 cases) and a corresponding control group (56 cases). The control group will receive stationary treatment, and the study group will receive individualized treatment based on CM syndrome differentiation in addition to stationary treatment. The study duration will be 50 weeks, comprising a 2-week run-in period, 24 weeks of intervention, and 24 weeks of follow-up. The outcomes will assess efficacy of treatment, improvement in CM symptoms, safety assessments, adherence to the treatment, and adverse events. CONCLUSION This study will provide evidence of evidence-based medicine for CM treatment in two or multiple microvascular complications caused by T2DM. (Registration No. ChiCTR-IPR-15007072).

Objective: To investigate the safety and efficacy of pancreatic kininogenase combined with sildenafil in the treatment of erectile dysfunction(ED) in type 2 diabetes mellitus (DM) patients in the high-altitude area. METHODS: This study included 93 ED patients with type 2 DM, all residents of the Xining area 1500 meters above sea level. We randomly divided them into an experimental group (n = 48) and a control group (n = 45), the former treated with pancreatic kininogenase(120 u, tid) and sildenafil (25 mg, qd at bedtime), while the latter with sildenafil only (25 mg, qd at bedtime).After 4 and 8 weeks of medication, we obtained the penile hemodynamic parameters,IIEF-5 scores, and sexual intercourse satisfaction(SIS) scores and compared them between the two groups of patients. RESULTS: There were no statistically significant differences in age or DM course between the two groups of patients (P >0.05).Compared with the baseline, both the experimental and control groups showed remarkably improvement inthe IIEF-5 score (8.81 ± 2.06 vs 11.54 ± 7.72 and 8.29 ± 1.91 vs 9.37± 1.65, P <0.05), SIS score (3.35 ± 2.43vs6.83± 2.61and 3.41 ± 2.38 vs 4.92± 2.49, P <0.05), and penile hemodynamic parameters obtained by color duplex Doppler ultrasonography(P <0.05), with significant differences between the two groups in the IIEF-5 score (11.54 ± 7.72 vs 9.37± 1.65, P <0.05) and SIS score (6.83± 2.61 vs 4.92± 2.49, P <0.05) but not in the penile hemodynamic parameters (P >0.05). Even more remarkable improvement was observed at 8 weeks in the experimental and control groups in the IIEF-5 score (19.29± 1.85 and 15.43± 1.74)(P <0.05), SIS score (11.73 ± 2.57 and 6.55± 2.71) (P <0.05), and penile hemodynamic parameters(P <0.05), all with significant differences between the two groups (P <0.05). CONCLUSIONS Pancreatic kininogenase combined with sildenafil has a better clinical effect than sildenafil alone on ED in type 2 DM patientsin the high-altitude area.

As more and more studies suggest that type 2 diabetes mellitus (T2DM) is closely related to male hypogonadism, people begin to pay more attention to the role of testosterone in the development of T2DM and the effect and safety of testosterone supplementary therapy. There is some controversy in randomized controlled studies and meta-analyses about the effects of testosterone supplementation on the blood glucose level, androgen deficiency symptoms, and cardiovascular diseases. This review focuses on the diagnosis of hypogonadism in T2DM males, differences in the therapeutic effects and safety of testosterone replacement among different studies, and rational use of testosterone supplementation for T2DM patients.
