Nonalcoholic fatty liver disease (NAFLD) and type 2 Diabetes Mellitus (T2DM) are highly prevalent diseases and are closely associated, with NAFLD being present in the majority of T2DM patients. In Asian traditional medicine, Mori Cortex is widely used for the treatment of diabetes and hyperlipidemia. However, whether it has a therapeutic effect on T2DM associated with NAFLD is still unknown. The present study showed that the oral treatment with Mori Cortex extract (MCE; 10 g·kg·d) lowered the blood lipid levels and reversed insulin resistance (IR) in high fat-diet/streptozotocin-induced type 2 diabetes in rats. The expression levels of sterol receptor element-binding protein-1c (SREBP-1c) and carbohydrate-responsive element binding protein (ChREBP), which are involved in steatosis in NAFLD rats, were measured in the liver samples. MCE decreased the protein and mRNA expression levels of SREBP-1c and ChREBP. In conclusion, down-regulation of SREBP-1c and ChREBP might contribute to the protective effect of MCE on hepatic injury and IR in the rats with T2DM associated with NAFLD.

OBJECTIVE:
The present study aims at determining the stability of a popular type 2 diabetes rat model induced by a high-fat diet combined with a low-dose streptozotocin injection.
METHODS:
Wistar rats were fed with a high-fat diet for 8 weeks followed by a one-time injection of 25 or 35 mg/kg streptozotocin to induce type 2 diabetes. Then the diabetic rats were fed with regular diet/high-fat diet for 4 weeks. Changes in biochemical parameters were monitored during the 4 weeks.
RESULTS:
All the rats developed more severe dyslipidemia and hepatic dysfunction after streptozotocin injection. The features of 35 mg/kg streptozotocin rats more resembled type 1 diabetes with decreased body weight and blood insulin. Rats with 25 mg/kg streptozotocin followed by normal diet feeding showed normalized blood glucose level and pancreatic structure, indicating that normal diet might help recovery from certain symptoms of type 2 diabetes. In comparison, diabetic rats fed with high-fat diet presented decreased but relatively stable blood glucose level, and this was significantly higher than that of the control group (P<0.05).
CONCLUSIONS
This model easily recovers with normal diet feeding. A high-fat diet is suggested as the background diet in future pharmacological studies using this model.

OBJECTIVETo compare the efficacy between acupuncture at stellate ganglion combined with intravenous administration of alprostadil and simple intravenous administration of alprostadil on lower limb atherosclerosis of early diabetes mellitus.
METHODSSixty patients of lower limb atherosclerosis of early diabetes mellitus were randomly divided into an observation group and a control group, 30 cases in each one. Patients in the two groups were treated with basic treatment to control blood glucose and lipid. In addition, patients in the control group were treated with intravenous administration of alprostadil (10 µg) and sodium chloride solution (100 mL); based on this, patients in the observation group were treated with acupuncture at stellate ganglion. The treatment was given once a day; the consecutive treatment of two weeks constituted one session, and totally 4 sessions were given. The total syndrome score, glycosylated hemoglobin (HbA1c), blood flow of posterior tibial artery and dorsal artery of foot were observed before and after treatment; the clinical efficacy was compared between the two groups.
RESULTSCompared before treatment, the total syndrome score, HbA1c, blood flow of posterior tibial artery and dorsal artery of foot were significantly improved after treatment (all P < 0.05), which were more obvious in the observation group (all P < 0.05). After treatment, the total effective rate was 93.3% (28/30) in the observation group, which was significantly superior to 86.7% (26/30) in the control group (P < 0.05). CONCLUSION Acupuncture at stellate ganglion combined with intravenous administration of alprostadil achieve better effect than simple intravenous administration of alprostadil for lower limb atherosclerosis of early diabetes mellitus, which improve the clinical symptoms, regulate blood sugar and increase the blood flow of lower limb.

OBJECTIVETo evaluate the long-term clinical effect of Tangyiping Granules (, TYP) on patients with impaired glucose tolerance (IGT) to achieve normal glucose tolerance (NGT) and hence preventing them from conversion to diabetes mellitus (DM).
METHODSIn total, 127 participants with IGT were randomly assigned to the control (63 cases, 3 lost to follow-up) and treatment groups (64 cases, 4 lost to follow-up) according to the random number table. The control group received lifestyle intervention alone, while the patients in the treatment group took orally 10 g of TYP twice daily in addition to lifestyle intervention for 12 weeks. The rates of patients achieving NGT or experiencing conversion to DM as main outcome measure were observed at 3, 12, and 24 months after TYP treatment. The secondary outcome measures included fasting plasma glucose (FPG), 2-h postprandial plasma glucose (2hPG), glycosylated hemoglobin (HbA1c), fasting insulin (FINS), 2-h insulin (2hINS), homeostatic model assessment of insulin resistance (HOMA-IR), blood lipid and patients' complains of Chinese medicine (CM) symptoms before and after treatment.
RESULTSA higher proportion of the treatment group achieved NGT compared with the control group after 3-, 12- and 24-month follow-up (75.00% vs. 43.33%, 58.33% vs. 35.00%, 46.67% vs. 26.67%, respectively, P<0.05). The IGT to DM conversion rate of the treatment group was significantly lower than that of the control group at the end of 24-month follow-up (16.67% vs. 31.67%, P<0.05). Before treatment, FPG, 2hPG, HbA1c, FINS, 2hINS, HOMA-IR, triglyceride (TG), total cholesterol, low- and high-density lipoprotein cholesterol levels had no statistical difference between the two groups (P>0.05). After treatment, the 2hPG, HbA1c, HOMA-IR, and TG levels of the treatment group decreased significantly compared with those of the control group (P<0.05). CM symptoms such as exhaustion, irritability, chest tightness and breathless, spontaneous sweating, constipation, and dark thick and greasy tongue were significantly improved in the treatment group as compared with the control group (P<0.05). No severe adverse events occurred.
CONCLUSIONTYP administered at the IGT stage with a disciplined lifestyle delayed IGT developing into type 2 DM.

Differences in arterial stiffness between the two sides of the carotid arteries were investigated using ultrasonic radiofrequency in 88 patients with type 2 diabetes and 70 controls. The compliance coefficient (CC), pulse wave velocity (PWV), intima-media thickness (CIMT) and diameter (CCAD) of the common carotid arteries (CCAs) were measured. The ratio of the left to right CCAs was calculated to provide four indexes: CC ratio, PWV ratio, CIMT ratio and CCAD ratio. In the diabetes group, the PWV on the left side was significantly higher than that on the right side, while the CC on the left side was significantly lower than that on the right side. The bilateral CIMT was thicker and CCAD was wider, the left PWV traveled faster, and the right CC was higher in the diabetes group than in the control group. The PWV ratio between the two groups was significantly different and correlated positively with duration of diabetes and systolic blood pressure (SBP). The differences between the two sides of CCAs in patients with diabetes suggested that disease duration and SBP were important risk factors for arterial stiffness. Identifying the difference could potentially lead to the much earlier diagnosis of arteriosclerosis.

7.Avoiding or coping with severe hypoglycemia in patients with type 2 diabetes.
The Korean Journal of Internal Medicine 2015;30(1):6-16
Hypoglycemia is a major barrier to achieving the glycemic goal in patients with type 2 diabetes. In particular, severe hypoglycemia, which is defined as an event that requires the assistance of another person to actively administer carbohydrates, glucagon, or take other corrective actions, is a serious clinical concern in patients with diabetes. If severe hypoglycemia is not managed promptly, it can be life threatening. Hypoglycemia-associated autonomic failure (HAAF) is the main pathogenic mechanism behind severe hypoglycemia. Defective glucose counter-regulation (altered insulin secretion, glucagon secretion, and an attenuated increase in epinephrine during hypoglycemia) and a lack of awareness regarding hypoglycemia (attenuated sympathoadrenal activity) are common components of HAAF in patients with diabetes. There is considerable evidence that hypoglycemia is an independent risk factor for cardiovascular disease. In addition, hypoglycemia has a significant influence on the quality of life of patients with diabetes. To prevent hypoglycemic events, the setting of glycemic goals should be individualized, particularly in elderly individuals or patients with complicated or advanced type 2 diabetes. Patients at high-risk for the future development of severe hypoglycemia should be selected carefully, and intensive education with reinforcement should be implemented.

Chinese Acupuncture & Moxibustion 2015;35(4):330-334
OBJECTIVETo observe the clinical efficacy of BO's abdominal acupuncture for obese type-2 diabetes mellitus (T2DM).
METHODSSixty patients of obese T2DM were randomly divided into an acupuncture group and a medication group, 30 cases in each one. Patients in the medication group were treated with basic treatment combined with oral administration of regular antidiabetics, three weeks as one session. Patients in the acupuncture group, based on the medication group, were treated with abdominal acupuncture at Yinqiguiyuan [Zhongwan (CV 12), Xiawan (CV 10), Qihai (CV 6), Guanguan (CV 4)], Fusiguan [Huaroumen (ST 24), Wailing (TE 5)], Tianshu (ST 25), Daheng (SP 15), Qixue (KI 13), etc.; the treatment was given three times per week, 3 weeks as one session. The systolic blood pressure (SBP), diastolic blood pressure (DBP), body weight, waist circumference (WC), hip circumference, body mass index (BI) were observed before and after treatment in the two groups, and fasting plasma glucose (FPG), fasting insulin (FINS), 2-hours postprandial blood glucose by oral glucose tolerance test (OGTT) and insulin, total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C), HOMA-IR of insulin resistance index were calculated and adverge events were recorded.
RESULTSCompared before the treatment, SBP, WC, body weight, BMI, FPG, OG-TT2hBG, FINS, GTT2h insulin, HOMA-IR, TC and LDL-C in the acupuncture group were all significantly reduced (all P <0. 05), while FPG, OGTT2H insulin and TG were increased in the medication group (all P<0. 05)'. The differences of reducing SBP, WC, FPG, OGTT2H insulin, HOMA-IR, TC, TG and LDL-C were statistically significant between the two groups (all P<0. 05). The total effective rate was 93. 3% (28/30) in the acupuncture group, which was significantly superior to 23. 3% (7/30) in the medication group (P<0. 01).
CONCLUSIONBO's abdominal acupuncture has obvious clinical efficacy for obese type-2 diabetes mellitus, featuring in lowering blood pressure, reducing weight, decreasing blood glucose, im- proving insulin resistance and lowering lipid, which has no adverse effects and is worthy of clinical popularization and application.

BACKGROUND/AIMS: Poor sleep quality (SQ) is associated with increased cardiovascular mortality and morbidity. Additionally, asymmetric dimethylarginine (ADMA) is an independent predictor of cardiovascular mortality and morbidity. However, no sufficient data regarding the relationship between ADMA levels and SQ have been reported. The goal of the current study was to evaluate the association between SQ and ADMA levels in normotensive patients with type 2 diabetes mellitus. METHODS: The study participants consisted of 78 normotensive type 2 diabetics. The SQ of all participants was assessed using the Pittsburgh Sleep Quality Index (PSQI). Patients with a global PSQI score > 5 were defined as "poor sleepers." Factors associated with poor SQ were analyzed using a multiple regression model. Serum ADMA levels were measured using high performance liquid chromatography. RESULTS: The median ADMA levels of the poor sleepers were increased compared with patients defined as good sleepers (5.5 [4.2 to 6.6] vs. 4.4 [2.9 to 5.4], p < 0.01, respectively). However, the L-arginine/ADMA ratio was decreased in poor sleepers (p < 0.01). Global PSQI scores were positively correlated with ADMA levels (p < 0.01) and negatively correlated with the L-arginine/ADMA ratio (p = 0.02). ADMA levels were correlated with sleep latency (p < 0.01) and sleep efficiency (p = 0.01). Logistic regression analysis showed that ADMA levels (odds ratio [OR], 1.68; 95% confidence interval [CI], 1.16 to 2.44; p = 0.01) and body mass index (OR, 1.15; 95% CI, 1.01 to 1.31; p = 0.04) were associated with poor SQ independently of glomerular filtration rate, sex, age, duration of diabetes, hemoglobin A1c, total cholesterol, and systolic blood pressure. CONCLUSIONS: Self-reported SQ was independently associated with ADMA levels in normotensive patients with diabetes mellitus.

China Journal of Chinese Materia Medica 2015;40(5):957-962
To study the protective effect of Arctigenin in goto-kakizaki (GK) rats combined with hypertension macroangiopathy. Six-week-old GK rats were divided randomly according to blood glucose level into four groups: the model group and low, middle and high dose arctigenin groups (12.5, 25, 50 mg x kg(-1)), with Wistar rats as the normal group. All of GK rats were given high-glucose and high-fat diet. After 16 weeks, GK rats were orally administrated with 10 mg x kg(-1) x d(-1) N-Ω-nitro-L-arginine methyl ester for eight weeks. During the modeling, all of arctigenin groups were orally administrated with different dose of arctigenin twice a day; The model group and the normal group were given solvents. At the beginning, mid-term and end of the experiment, blood glucose was measured. At the end of the experiment, efforts were made to detect blood pressure, collect abdominal aortic blood after anesthesia, fix thoracic aorta after bloodletting to make paraffin sections, observe morphological characteristics and detect the expression of VEGF by immunohistochemistry. According to the results, the blood glucose rose in all GK rats, with no significant difference between the drug group and the model group. At the end of the experiment, the blood pressure significantly increased in GK rats, indicating that Arctigenin could notably reduce the blood pressure in GK rats in a dose-dependent manner. The blood routine test showed increases in both the total white blood cell count and differential blood count, MPV and PDW, abnormal blood platelet parameters and decrease in PLT in GK rats, suggesting that Arctigenin could remarkably reduce the total white blood cell count and differential blood count, MPV and PDW. The thoracic aortic morphological observation revealed obvious endangium lesions in GK rats, demonstrating that Arctigenin could ameliorate the lesion extent. VEGF immumohistochemical staining showed a higher VEGF expression in the model group but lower expression in Arctigenin groups. In conclusion, Arctigenin had a protective effect on aorta in GK rats. Its mechanism may be related to blood pressure lowering, anti-inflammation, improvement in blood platelet function and reduction of VEGF expression.
