OBJECTIVETo observe the effect of Zhenqing Recipe (ZQR) on non-alcoholic fatty liver (NAFL), and the expression of hepatic salt-inducible kinase 1 (SIK1) and sterol-regulatory element binding protein-ic (SREBP-lc) in type 2 diabetes rats.

METHODSA rat model of type 2 diabetes was established by high fat/sucrose diet combined with intraperitoneal injection of small dose streptozotocin (STZ) . Modeled rats were randomly divided into the model group, the ZQR group, and the metformin group, 8 in each group. Eight rats were recruited as a normal control group. ZQR at the daily dose of 12 g crude drugs/kg was administered to rats in the ZQR group by gastrogavage. Metformin suspension at the daily dose of 150 mg/kg was administered to rats in the metformin group by gastrogavage. Equal volume of distilled water was administered to rats in the normal control group and the model group. All medication lasted for 12 weeks. The levels of fasting blood glucose (FBG), free fatty acid (FFA), serum triglyceride (TG), serum total cholesterol (TC), serum alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were detected. The body weight and wet liver weight were weighed, and the liver weight index calculated. The liver TG content was measured. The pathological changes of liver and the expression of SIK1 were observed by HE staining and immunohistochemistry. The mRNA and protein expression of SIK1 and SREBP-1c were detected using RT-PCR and Western blot.

RESULTSCompared with the normal control group, FBG, FFA, TG, TC, ALT, AST, liver weight index, and liver TG contents significantly increased (P < 0.01); liver steatosis was severe, the mRNA and protein expression of SIK1 obviously decreased (P < 0.01); mRNA and protein expression of SREBP-1c increased (P < 0.01). After drug therapy, compared with the model group, FBG, FFA, TG, TC, ALT, AST, and liver weight index significantly decreased, liver TG contents significantly decreased, the mRNA and protein expression of SIK1 obviously increased, while mRNA and protein expression of SREBP-1c obviously decreased (P < 0.05, P < 0.01) in the ZQR group and the metformin group (P < 0.05, P < 0.01); and the pathological changes were also improved. All the indices were improved more in the ZQR group (all P < 0.05).

CONCLUSIONIn this experiment, we found that the expression of SIK1 decreased in NAFL rats with type 2 diabetes. ZQR could alleviate lesion of NAFL type 2 diabetes rats possibly by up-regulating hepatic SIK1 expression at mRNA and protein levels.

Objective:To explore the clinical characteristics and risk factors of severe and critical influenza in children.Methods:The clinical data of 214 inpatient children with severe and critical influenza hospitalized in the Second Affiliated Hospital & Yuying Children′s Hospital of Wenzhou Medical University from January 1, 2016 to December 31, 2019 were retrospectively collected. The clinical characteristics including age, gender, symptoms, signs, underlying diseases, C-reactive protein (CRP), treatment and outcome of children with severe and critical influenza were compared. Chi-Square test was used for statistical analysis. A binary logistic regression model was constructed to analyze the risk factors for critically ill influenza.Results:Of the 214 children, 153 were male (71.5%), 177(82.7%) were under 5 years old. There were 52 children with underlying diseases. Fever occurred in 207 cases. Among the 54 cases that had convulsion during the course of the disease, three developed acute necrotizing encephalopathy. The influenza subtype was mainly type A, accounting for 190(88.79%). A total of 42(19.6%) children were critically ill. The incidence of critical influenza in children with underlying diseases (61.9%, 26/42) was higher than that in severe influenza children (15.1%, 26/172), and the difference was statistically significant ( χ2=40.175, P<0.01). The incidence of critical influenza in children with CRP≥40 mg/L was higher than that of severe influenza in children with CRP ≥40 mg/L (33.3%(14/42) vs 9.3%(16/172)), and the difference was statistically significant ( χ2=16.173, P<0.01). Multivariate logistic regression showed that underlying diseases (odds ratio ( OR)=8.794, 95% confidence interval ( CI) 3.845-20.111) and CRP ≥40 mg/L ( OR=5.050, 95% CI 1.966-12.970) were risk factors for critical influenza. All severe cases were improved and discharged.Among the 42 critically ill children, seven children died. Conclusions:Among the severe and critical influenza in children, the majority of children are under five years old.Underlying diseases and CRP ≥40 mg/L are risk factors for critical influenza.

Objective: To study the influence of high cell incubating temperature on AMP-activated protein kinase(AMPK) activity and lipid metabolites of piglets hepatocytes in vitro.Method: Primary hepatocytes of piglets about age 55d were separated and cultured under 37 ℃(control) or 42 ℃(heat stress).The anabolic and catabolic products of [14C]-oleic acid were detected for hepatocytes and culture media at 60min,120min and 180min.There were 9 replicates per time point.Result: Heat stress activated AMPK activity and enhanced fatty acid oxidation.The production of [14C]-CO2 and [14C]-acid soluble metabolites(ASM) was higher in heat stress group than in the control.At the same time,heat stress depressed the incorporation of [14C]-oleate into phospholipids,monoglycerides,triglycerides,cholesterol and cholesteryl ester.Conclusion: Heat stress activated AMPK activity and enhanced the formation of anabolic products and depressed catabolic products in piglets hepatocytes in vitro.

ObjectiveTo examine the effects of proprioceptive neuromuscular facilitation(PNF) techniques on lower limb motor function of strokes and its mechanism.MethodsWe used simple random sampling and cross-section survey design. PNF Contract Relax Agonist Contract(PNF-CRAC) techniques were applied to 44 stroke patients. Surface electromyography values(sEMG) was recorded from rectus femoris and hamstring of stroke patients with both low limbs. ResultsPNF-CRAC techniques not only caused the irradiation of muscles activities in the contralateral extremity during unilateral exercise, but also increased agonist EMG activities and the motor control of knee joint in strokes.ConclusionPNF-CRAC techniques can improve the knee stability and enhance the recovery of motor function in paretic lower limb.

Objective To study correlation between MRI signal intensity of the lumbar intervertebral disc and collagen content in the nucleus pulposus.Methods Thirty-one cases with lumbar intervertebral disc herniation(male 21,female 10)received percutaneous lumbar disketetomy.Thirty-one specimens of nucleous pulposus were obtained from percutaneous lumbar disketctomy procedure and collagen content in them was measured with reformed hydroxyproline measurement method.The signal intensity(SI) of lumbar intervertebral disc and cerebrospinal fluid was measured in T_2 WI sagittal image and then ratio of disc SI to cerebrospinal fluid SI was calculated.The Pearson analysis was used to analyze the correlation between the collagen content and SI ratio and disc SI on T_2 WI.Results Collagen content and SI ratio were (231.0?63.5)mg/g and 0.19?0.07,respectively.There was negative correlation between them (r=-0.61,P

OBJECTIVETo study on the reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in total knee arthroplasty (TKA) the rotational alignment reference bony landmarks of the proximal tibial component on magnetic resonance image (MRI) were measured.

METHODSFrom January 2010 to December 2013, 80 normal knees of Chinese volunteers including 35 males and 45 females with an average age of (35.4±6.1) years were reviewed. The images of the knees were obtained by MRI. The surgical epicondylar axis (STEA) was identified in the femoral transverse sections and then was projected to the side of tibia, forming the SETA'. A line connecting the medial border of the patellar tendon and the middle of the posterior cruciate ligament insertion (Akagi line) and its vertical line (AK), as well as a line connecting the medial 1/3 of the patellar tendon and the middle of the posterior cruciate ligament insertion and its vertical line (AP), were identified in the tibial transverse sections. The angles were measured between the AK, AP and STEA'.

RESULTSThe angle between AK and STEA' was (0.59±2.07)°, and there was no significant difference between the two lines (t=-2.54, P=0.13). The mean angle between AP and STEA' was (3.21±2.04)°, and there was a significant difference between the two lines (t=14.05, P<0.05). There was a significant difference between the AK and AP (t=-11.68, P<0.05).

CONCLUSIONThe reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in TKA is good.

Objective:To observe influence of alprostadil injection on contrast-induced nephropathy (CIN) in high risk patients after percutaneous coronary intervention (PCI).Methods: A total of 263 CIN high risk (CIN risk score ≥16 scores) patients were selected.According to random number table, patients were randomly divided into routine treatment group (n=121, received routine hydration therapy) and alprostadil group (n=142, received additional alprostadil injection based on routine treatment group).Serum creatinine (SCr), glomerular filtration rate(GFR), cystatin C (CysC) and β trace protein (β-TP) level before, 48h and 72h after PCI were measured and compared, and incidence rate of CIN, percentage of blood purification therapy and mortality were compared between two groups.Results: Compared with before PCI, there was significant rise in SCr level and significant reduction in GFR in both groups on 48h and 72h after PCI (P<0.01 all);Compared with routine treatment group, there were significant reductions in levels of SCr [72h: (190.04±28.92) μmol/L vs.(141.10±21.18) μmol/L], and significant rise in GFR [72h: (26.0±4.4) ml/min vs.(36.4±4.9) ml/min], and levels of CysC[72h: (1.75±0.74) mg/L vs.(1.47±0.55) mg/L] and β-TP [72h: (1.53±0.50) mg/L vs.(1.22±0.38) mg/L] significantly decreased in alprostadil group on 48h and 72h after PCI, P<0.05 or <0.01;there were significant reductions in incidence rate of CIN (30.6% vs.18.3%) and percentage of blood purification therapy (10.7% vs.3.5%) in alprostadil group, P=0.001, 0.045 respectively.There was no significant difference in mortality between two groups, P=0.728.Conclusion: Alprostadil injection can significantly improve kidney function, reduce incidence rate of CIN and percentage of blood purification therapy in CIN high risk patients after PCI, which is worth extending.

This study aimed to explore the impact of depression caused by chronic unpredictable mild stress (CUMS) on in vivo activity of six kinds of CYP450 isoforms in rats. According to 'Katz' method, the model of CUMS was established. Tolbutamide, chlorzoxazone, theophylline, midazolam, omeprazole and dextromethorphan were chosen as probe substrates of CYP2C6, CYP2E1, CYP1A2, CYP3A2, CYP2D1 and CYP2D2 of rats. Plasma concentration of six kinds of CYP450 in control group and model group were determined by LC-MS/MS and computed pharmacokinetic parameters. Consequently, metabolism of theophylline and chlorzoxazone accelerated significantly (P < 0.01), but tolbutamide, dextromethorphan, omeprazole and midazolam had no significant difference. The present study proved that depression caused by CUMS had strong induction to CYP1A2 and medium induction to CYP2E1.
