To study the protective effect of astragalus saponin extracts (AS) on kidneys of diabetic rats. Totally 32 diabetic rats induced by streptozotocin (STZ) were divided into AS high and low dose groups, the positive control group and the model group (DM group) and orally administered with 50 mg x- kg(-1) x d(-1) AS 200, 25 mg x kg(-1) x d(-1) valsartan, 10 mL x kg(-1) x d(1) physiological saline, respectively. Another 8 healthy rats were collected in the normal control group (NC group, physiological saline 10 mL x kg(-1). d(-1)). All rats were treated for consecutively 6 weeks. After the administration, the body weight was measured every week, the concentration of blood glucose was monitored on week 2, 4 and 6. The total urine and total urinary protein (U-TP) in 24 h were measured by the metabolic cage method on week 6; At the end of week 6, blood samples were collected from hearts to detect blood urea nitrogen (BUN), serum creatinine (Scr), uric acid (UA) , total cholesterol (CH) triglyceride (TG) by biochemical methods. Kidneys were collect to calculate the kidney hypertrophy index and observe the pathological sections. The laboratory results show that in the DM group, the blood glucose, metabolic cost in 24 h, kidney hypertrophy index, U-TP, BUN, Scr, UA, TG were significantly higher than that in the NC group (P < 0.01, P < 0.05) , with significant pathological changes; After the intervention with AS, the metabolic value in 24 h, kidney hypertrophy index, U-TP, BUN, Scr, UA, TG were significantly lower in the high dose group (P < 0.01, P < 0.05), and the kidney hypertrophy index, BUN, Scr, UA, TG in the low dose group were also significantly lower (P < 0.05), with slight reduction in renal pathological changes in both groups. In conclusion, Astragalus saponin extracts have a certain protective effect on kidneys of diabetic rats.

Objective To summarize the domestic design for placebo acupuncture and the placebo effect and explore an ideal design for placebo acupuncture.Method Three large Chinese databases CNKI, Wan Fang and Vip were searched to systematically review the application of placebo acupuncture in randomized controlled trials published at home in recent 5 years (2011.01—2016.11).Results and conclusions A total of 48 articles were included according the inclusion and exclusion criteria. An analysis was made of the kinds of diseases for acupuncture study, the methods of designing placebo acupuncture, the effects of placebo acupuncture and comparisons with foreign placebo acupuncture. Pain syndrome and insomnia were the main kinds of diseases for acupuncture study, accounting for 10 and 8 articles respectively. Acupuncture needles were the main kind of needles for placebo acupuncture, accounting for 66.6%. Sites beside acupoints were the main positions selected for placebo acupuncture, accounting for 58.3%. Not penetrating the skin predominated in the depth of needle insertion, accounting for 37.5%. The kinds of needles for placebo acupuncture were fewer than abroad. The effects of placebo acupuncture were not superior to those of acupuncture.

This study is to investigate the effect of total flavonoids of Uygur medicine bugloss (BTF) on rats with myocardial ischemia/reperfusion injury, and to explore the mechanisms by which it acts. Left anterior descending (LAD) coronary artery in rats was occluded for 30 min followed by 4 h reperfusion. Meanwhile, BTF dissolved in saline was administered intraperitoneally at dosage of 10, 30 and 50 mg x kg(-1). Electrocardiograph, infarction index, serum myocardial enzymes and heart function were determined to evaluate the effect of BTF. Some other observations were carried out to explore whether inhibiting inflammation and apoptosis is involved in the mechanisms underlying BTF. Our results showed that in ischemia/reperfusion injured rats BTF could dose-dependently reduce myocardial infarction index and myocardial enzyme leakage, and enhance heart function, indicating that it possesses significant cardio protection. ELISA analysis showed that BTF could decrease the content of myocardial inflammatory cytokines such as IL-1beta, IL-6 and TNF-alpha. Western-blotting confirmed that BTF could increase the expression of anti-apoptotic protein Bcl-2 and reduce the expression of proapoptosis protein Bax. Further more, the phosphorylation level of PI3K and Akt was upregulated by BTF treatment. BTF can protect rat against myocardial ischemia/reperfusion injury. Anti-inflammation and inhibition of apoptosis through upregulating PI3K/Akt signal pathway may contribute to the protective effect of BTF.

OBJECTIVETo explore the effects of different hepatic inflow occlusion methods on liver regeneration in rats after partial hepatectomy (PH).
METHODSMale Wistar-Furth rats were randomly assigned to three groups: control group, underwent 68% hepatectomy alone; occlusion of portal triad (OPT) group, subjected to occlusion of portal triad under portal blood bypass; and occlusion of portal vein (OPV) group, subjected to occlusion of portal vein under portal blood bypass. Blood flow was occluded for 20, 30, and 40 minutes before 68% hepatectomy. According to the 7-day survival of each group, a same occlusion time T was set. Each group was divided into two subgroups (n = 8), in which animals were killed 3 and 7 days later. Liver regeneration was calculated as a percent of initial liver weight. Immunohistochemistry for proliferating cell nuclear antigen (PCNA) and Ki-67 was performed to quantify proliferating cells. In addition, functional liver volume represented by 99Tc(m)-GSA radioactivity was assessed.
RESULTSThe safe tolerance limit time was 30 minutes for OPT group and 40 minutes for OPV group. At 3 days after PH, no significant difference was observed in the regeneration rate of each group (P > 0.05). However, liver radioactive activity, PCNA labeling index, and Ki-67 index of OPV group was significantly higher than those of OPT group (P < 0.05); the latter were similar to those of control group (P > 0.05). At 7 days after PH, no significant difference was observed in all indexes among three groups (P > 0.05).
CONCLUSIONCompared with Pringle maneuver, preserving the hepatic artery flow during portal triad blood inflow occlusion can promote remnant liver regeneration early after PH.

OBJECTIVETo analyze the influence of included angle between the anterior aspects of S2 and S vertebral bodies on pelvic inlet imaging in the pelvic midline sagittal plane.
METHODSTotally 58 axial pelvic CT scans were chosen as study objects including 43 males and 15 females,with an average age of 40.7 years old (ranged,18 to 68 years old). The angles between the anterior aspects of S2 and S1, vertebral bodies and the horizontal plane on midline sagittal CT reconstruction were measured to simulate the optimal S2 and S1 inlet angles. The included angle between the anterior aspects of S2 and S1 vertebral bodies was calculated by subtrocting the S1,inlet angle from the S2 inlet angle defined as a base number. Then, the impact of the calculated included angles on the pelvic inlet imaging was analyzed. Results:The S2 inlet angles averaged (30.5±6.5) degrees; the S inlet angles averaged (25.7±5.9) degrees. The difference between them was significant (t=3.35, P=0.001). Ten patients had zero angle between the anterior aspects of S2 and S1 vertebral bodies; 14 patients had negative angle, averaged-(8.9±8.1) degrees; 34 patients had positive angle,averaged (11.8+6.4) degrees.
CONCLUSIONThe difference of included angle between the anterior aspects of S2 and S1 vertebral bodies leads to the difference between S1 inlet view and S2 inlet view in most cases, complicating the pelvic inlet imaging,and affecting the reliability of the application of pelvic inlet view. Utilizing the angles measured on the preoperative midlihe sagittal CT reconstruction to obatin the patient-customized S1 and S2 inlet views could accurately guide the S1 and S2 iliosacral screw insertion.
