The influence of exercise training versus intensive insulin therapy on insulin resistance development in type 1 diabetes

The etiology of insulin resistance (IR) in Type 1 Diabetes (T1D) is unclear; however, intramyocellular lipids (IMCL) are likely contributors. While exercise lessens IR and IMCL content; T1D patients elevate glycemia to offset exercise-induced hypoglycemic risk. The preferred treatment for T1D patients is tight glucose management through intensive insulin therapy (IIT); however, IIT is accompanied with a sedentary lifestyle. The purpose of this study was to examine IR development and IMCL in combined exercise (DARE; aerobic/resistance) and IIT-treated T1D animals. 76 rats were divided into control sedentary (C), diabetic sedentary (CD), diabetes sedentary intensive insulin therapy (DIT) and DARE groups. Following streptozotocin (STZ), glycemia was maintained at either 9-15 mM (CD, DARE) or 5-9 mM (DIT) using insulin. DARE alternated between running and weighted climbing for 12 weeks. Results demonstrate that DARE exhibited reduced onset of IR compared with C, DIT and CD, indicated by increased glucose infusion rate (hyperinsulinemic-euglycemic-clamp). A shift in lipid metabolism was evident whereby diacylglycerol was elevated in DIT compared to DARE, while triacylglycerol was elevated in DARE. These findings indicate enhanced IMCL metabolism and the sequestration of fat as neutral triacylglycerol leads to reduced IR in DARE. In contrast, IIT and sedentary behavior leads to diacylglycerol accumulation and IR.     

火针点刺承泣穴治疗周围性面瘫后遗溢泪症的临床观察

ObjectiveTo compare the clinical therapeutic effect on epiphora as sequela of peripheral facial paralysis treated with pricking technqiue of fire needling therapy at Chéngqì (承泣 ST1) and acupuncture treatment at conventional acupoints.MethodsFrom September 2018 through to October 2018, 64 cases of epiphora as sequela of peripheral facial paralysis were collected from the Department of Acupuncture-Moxibustion in Suzhou TCM Hospital. According to random number table, they were divided into an observation group and a control group, 32 cases in each one. In the observation group, pricking technique of fire needling therapy was used at ST1, once every two days. In the control group, acupuncture with filiform needle was applied to Jīngmíng (睛明BL1), Tàiyáng (太阳EX-HN5), Tóngzĭliáo (瞳子髎GB1), Sìbái (四白ST2) and Quánliáo (颧髎SI18) on the affected side as well as Hégŭ (合谷LI4) on the contralateral side, once per day. The 10-day treatment was as one 1 course and the consecutive 3 courses of treatment were required in either of the groups. Before and after treatment, Munk grade, clinical effective rate and the number of treatments were observed in the evaluation of therapeutic effect.ResultsAfter treatment, Munk grade was improved in the patients of the two groups (both P < 0.05). The improvement range in the observation group was larger than that of the control group (P < 0.05). The treatment in either group achieved the obviously therapeutic effect on epiphora as sequela of peripheral facial paralysis. The effective rate in the observation group was 90.32%, higher than 61.29% in the control group (P < 0.05). The mean number of treatments of the curative case were 5.11 in the observation group and were 13.73 in the control group, indicating the statistical significance in difference (P < 0.05).ConclusionPricking technique of fire needling therapy at ST1 achieves the better effect on epiphora as sequela of peripheral facial paralysis as compared with acupuncture at conventional acupoints.

Effect of new glucose-lowering drugs on stroke in patients with type 2 diabetes: A systematic review and Meta-analysis

AimsPeople with diabetes tend to face a higher risk of stroke. Randomized controlled trials (RCTs) have demonstrated the different outcomes of new glucose-lowering drugs marketed in recent years on cardiovascular outcome events. The effects of glucagon-like peptide-1 (GLP-1) agonists, sodium-glucose cotransporter-2 (SGLT-2) inhibitors, and dipeptidyl peptidase-4 (DPP-4) inhibitors on stroke risk were evaluated in published RCTs.MethodsA search of Embase, Cochrane Library, and PubMed databases identified studies with stroke as an outcome event up to 3 December 2021. Risk ratios for stroke outcomes were analyzed using a fixed-effects model. I² was used to assess the heterogeneity of the study.Results19 RCTs with 155,027 participants with type 2 diabetes were identified. Pooled analysis showed that compared to placebo, GLP-1 agonists reduced non-fatal stroke by 15 % (RR = 0.85, 95%CI 0.77–0.94, P = 0.002, I² = 0 %) and total stroke (RR = 0.84, 95%CI 0.77–0.93, P = 0.000, I² = 0 %) by 16 %. SGLT-2 inhibitors and DPP-4 inhibitors were not significantly associated with lower stroke risk.ConclusionsThis meta-analysis indicates that GLP-1 agonists have potential benefits for stroke. However, further studies are needed if GLP-1 agonists are to be used to reduce the risk of stroke in patients with type 2 diabetes. More research is also needed to investigate the effects of new glucose-lowering drugs on different stroke subtypes.Systematic review registrationThis protocol was registered on the International Prospective Register of Systematic Reviews (https://www.crd.york.ac.uk/PROSPERO/; registration number: CRD42022326382).     

基因多态性与复发性自然流产的相关性研究

复发性自然流产（recurrent spontaneous abortions,RSA）是指连续发生2次或2次以上流产者。RSA的病因复杂,包括胚胎染色体异常、免疫功能异常、黄体功能不足、感染、生殖道异常等。但目前仍有部分RSA患者病因及发病机制尚不清楚,遗传背景等因素的改变可能使部分人群易发生RSA[1]。近年来从免疫遗传角度提出了一些新的观点,认为RSA的发生与遗传有关。寻找RSA的易感基因或致病基因,从根本上阐明RSA的发病机理,是RSA治疗和预防的重要途径。     

The nature and characteristics of hypertriglyceridemia in a large cohort with type 2 diabetes

AimsTo determine the prevalence of mild, moderate and severe hypertriglyceridemia (HTG) in a large, diverse healthcare system cohort with type 2 diabetes (T2D) and to study associations between triglyceride levels and demographic factors, glycemic control, body weight and to investigate whether triglyceride levels associate with markers of fatty liver and renal disease.Methods19,086 individuals with T2D were studied between 2015 and 2020. We compared groups with normotriglyceridemia (<150 mg/dl [<1.7 mmol/l]), mild (150-199 mg/dl [1.7–2.25 mmol/l]), moderate (200-499 mg/dl [2.26–5.64 mmol/l]) or severe HTG (>499 mg/dl [>5.64 mmol/l]). We also performed univariate and multivariate correlational analyses with triglyceride level as a continuous variable.Results39 % had triglyceride levels ≥150 mg/dl (<1.7 mmol/l), 19 % had moderate and 2 % had severe HTG. There was a lower proportion of Blacks in all HTG categories compared to Whites. There was no overall gender difference in prevalence except that severe HTG was more common in men and as HTG severity worsened mean age fell. Triglycerides correlated with HbA1c and associated with BMI, LDL-C, diastolic BP, transaminases and urine albumin/creatinine ratio, independent of HbA1c.ConclusionThis study fills gaps in our knowledge of the distribution and clinical associations of HTG in T2D and characterizes the features of the small but important group with severe HTG. We demonstrate the influence of age, sex and race, confirm the moderate effects of glycemic control and obesity on triglyceride level, and provide evidence that triglyceride levels may be a marker for fatty liver and nephropathy independent of glycemic control.     

Acupuncture and Chinese herbs as treatments for depression: An Australian pilot study

AimsAims were to determine the effectiveness of acupuncture and Chinese herbs as treatments for depression, and to assess beliefs, attitudes and treatment experience.MethodParticipants received acupuncture or acupuncture and Chinese herbs combined for five weeks. Acupuncture was given for 30 min twice a week and herbs taken three times a day. A Beliefs and Attitudes questionnaire was administered at baseline and Treatment Experience questionnaire post treatment. Outcome measure was improvement in depressive symptoms at the end of treatment period.ResultsNineteen participants completed 5 weeks of treatment, 12 in the acupuncture group and 7 in the combined group. Treatment significantly improved depressive symptoms, however, there were no differences between groups. At baseline, participants were positive about the perceived effectiveness of treatment, and treatment experiences were positive.ConclusionsAcupuncture was effective in reducing depressive symptoms. However, herbs did not have an additional treatment effect. Beliefs and attitudes were positive.     

The effectiveness and safety of acupuncture for depression: An overview of meta-analyses

PurposeTo provide an overview of existing meta-analysis (MAs) on the efficacy and safety of acupuncture for depression, and assess the methodological quality and the strength of evidence of the included MAs.MethodsWe searched MAs of randomized trials that have evaluated the effects of acupuncture on depression in three international and three Chinese databases from their inception until August 2019. The methodological quality of included MAs was evaluated with the Assessing the Methodological Quality of Systematic Reviews 2 (AMSTAR-2), and the strength of evidence with the Grading of Recommendations, Assessment, Development and Evaluation (GRADE). We used the intra-class correlation coefficient (ICC) to assess reviewer agreement in the pre-experiment.ResultsWe included 31 MAs and 59 RCTs. The results of included MAs were conflicting, our meta-analyses found that acupuncture may confer small benefit in reducing the severity of depression by end of treatment than no treatment/wait list/treatment as usual(SMD -0.74, 95% CI -1.06 to -0.41, eight trials, 624 participants), control acupuncture (invasive, non-invasive sham controls) (SMD 0.27, 95% CI -0.51 to -0.04, 20 trials, 1055 participants), antidepressants(Selective serotonin reuptake inhibitors (SSRI)/ Tetracyclic antidepressants(TCAs)) (SMD -0.28, 95% CI -0.46 to -0.10, 30 trials, 3068 participants), acupuncture plus antidepressants versus antidepressants(SSRI/TCAs) (SMD -0.99, 95% CI -1.37 to -0.61, 17 trials, 1110 participants). Subgroup analyses showed that there was no difference between electro-acupuncture and invasive control (P = 0.37), electro-acupuncture and non-invasive control (P = 0.90), manual acupuncture and Tetracyclic antidepressants (P = 0.57), electro-acupuncture and Tetracyclic antidepressants (P = 0.07). Six MAs concluded that acupuncture reduced the incidence of adverse events compared with antidepressants. The evaluation with AMSTAR-2 showed that the quality of included MAs was low or critically low. The results of the GRADE evaluation showed that the strength of evidence was low to very low for most outcomes.ConclusionsAlthough acupuncture appears to be more effective and safer than no treatment, control acupuncture and antidepressants, the quality of the available evidence was very low. Further methodologically rigorous and adequately powered primary studies are needed to confirm the effectiveness of acupuncture for depression.     

手捻针干预重症抑郁障碍共病失眠:证据来自多导睡眠图及血清生物标志物

ObjectiveThis study is conducted to determine effects of manual acupuncture (MA) in patients with a diagnosis of major depressive disorder (MDD) and comorbid insomnia.MethodsA total of 67 participants who met the inclusion criteria were randomly enrolled in a two-arm randomized, placebo controlled, patients-blind trial and allocated to a real-MA group (patients = 34) and a sham-MA group (patients = 33). Patients in the real-MA group were treated on ‘Five-shen acupoints’, including Sìshéncōng (四神聪 EX-HN 1), Shéntíng (神庭 GV 24), Shéndào (神道 GV 11), bilateral Běnshén (本神 GB 13), and bilateral Shénmén (神门 HT 7). Though being punctured on the same acupoints, patients in the sham-MA group were treated by a placebo acupuncture approach (Streitberger Placebo-needle). Each group received corresponding interventions every other day, three times a week for total eight weeks. Both polysomnography (PSG) and testing of serum biological markers such as neuropeptide Y (NPY) and substance P (SP) were performed at pre- and post-treatment. Additionally, the global scores of Pittsburgh sleep quality index (PSQI) and the global scores of 17-items Hamilton Depression Rating Scale (HAMD17) were used for assessing the subjective sleep and emotion experience of patients, respectively. Meanwhile, adverse effects were monitored and recorded.ResultsAfter eight-week treatment, the global scores of PSQI and global scores of HAMD17 declined significantly (both P < 0.05) in the real-MA group but not in the sham-MA group (both P > 0.05). According to the parameters of PSG, striking decline were observed in sleep latency (SL) and wake after sleep onset (WASO) and striking climb were observed in total sleep time (TST) and sleep efficiency (SE) in the real-MA group after treatment (P < 0.05, respectively) but not in the sham-MA group (P > 0.05, respectively). Additionally, there were no significant differences in awakening times (ATs) and rapid eyes movement sleep latency (REM-SL) in both two groups after treatment (both P > 0.05). Meanwhile, the expression of NPY increased significantly and the expression of SP decreased significantly in the real-MA group after interventions (both P < 0.05) while those indicators only slightly fluctuated in the sham-MA group (P > 0.05). No serious adverse event was reported in either real- or sham- MA group.Conclusion(1) MA may be a potential alternative therapy for improving MDD and comorbid insomnia (particularly in extending total sleep time and shortening wake-up duration and sleep latency) via upregulating the expression of NPY and downregulating the expression of SP; more importantly, this efficacy of acupuncture can not be replaced by sham-acupuncture acting on the same acupoints with the same treatment frequency. (2) There is insufficient evidence to prove that MA can effectively reduce the number of arousals.
