OBJECTIVETo explore effects of Tongxinluo Capsule (TC) on platelet activating factor (PAF), vascular endothelial function, thrombolysis in myocardial infarction (TIMI) blood flow, and heart function in acute myocardial infarction (AMI) patients after delayed percutaneous coronary intervention (PCI).

METHODSTotally 80 AMI inpatients were recruited at Department of Cardiology, People's Hospital of Jiangxi Province, from Jan. 2008 to Sep.2013. Those in line with inclusion criteria were randomly assigned to TC treatment group and the conventional treatment group by random digit table, 40 in each group. Besides, another 40 healthy subjects from examinees at Outpatient Department were recruited as a healthy control group. PCI was performed after 1-week treatment. Then blood samples were collected, and then blood contents of CD62P, CD63, GP II b/III a, ET-1, NO, and plasma von Willebrand factor (vWF) levels were detected. Coronary TIMI blood flow and corrected TIMI frame count (CTFC) were determined during PCI. Meanwhile, noninvasive blood pressure (BP) and heart rate (HR) were recorded before and after PCI, and cardiac function measured. They were compared with the healty control group.

RESULTSCompared with the healthy control group, blood contents of CD62p, CD63, GP II b/IIIa receptor compound, vWF, and ET-1 significantly increased, but NO significantly decreased in AMI patients (all P < 0.05). After 1-week intervention of TC, blood contents of CD62p, CD63, GP II b/IIIa receptor compound, vWF, NO, and ET-1 significantly decreased (P < 0.05, P < 0.01). Compared with the conventional treatment group at the same time point, blood contents of CD62p, CD63, GP II b/IIIa receptor compound, vWF, and ET-1 decreased more significantly in the TC group (P < 0.05, P < 0.01), increased NO levels were also more obviously seen (P < 0.01). The aforesaid parameters changed more obviously at day 30, as compared with those changes at week 1 (P < 0.05, P < 0.01). The TIMI blood flow grade and CTFC were more obviously improved after PCI in the two treatment groups. Better TIMI blood flow was seen in the TC group. TIMI level 3 blood flow rate was higher in the TC group than in the conventional treatment group with statistical difference (P < 0.05). The left ventricular ejective factor (LVEF) after PCI was obviously elevated in the TC group and the conventional treatment group (P < 0.01), and the improvement was more obviously seen in the TC group (P < 0.05). There were 6 cases of recurrent angina, 3 cases of ventricular tachycardial (VT)/ventricular fibrillation (VF), 6 cases of heart failure (HF), 1 case of cardiac sudden death in the conventional treatment group, with the total incidence of cardiovascular events being 40% (16/40). There were 2 cases of recurrent angina, 2 cases of VT/VF, 2 cases of HF, no cardiac sudden death in the TC treatment group, with the total incidence of cardiovascular events being 15% (6/40). There was statistical difference in the recurrent rate of cardiovascular events between the two groups (χ² = 2.27, P < 0.05).

CONCLUSIONTC not only could prevent coronary embolism of AMI patients after delayed PCI, attenuate vascular endothelial injury, but also could improve TIMI blood flow, and strengthen cardiac systolic function.

Objective To observe the effects of hepatic artery reconstruction in rat with orthotopic liver transplantation(OLT)on ultrastructure changes of intrahepatic biliary epithelial cells after ischemia reperfusion iniury and postoperative biliary complications. Methods Male SD rats were divided into sham operation group (SO),OLT with hepatic artery reconstruction group(HA)and OLT without hepatic artery reconstruction group (NA).The liver tissue samples were collected at 0.5,3,6,12,24,36,48 hours after ischemia reperfusion in both HA grouD and NA group.The uhrastructure of intrahepatic biliary epithelial cells was observed by transmission electron microscope,and the morphometric analysis by the computer image analysis system.The postoperative biliary complications were also observed.Results In HA group and NA group,the injury of intrahepatic biliary epithelial cells aggravated gradually along with the reperfusion.The uhrastructure changes,such as enlarged mitochondria,blurred or disappeared cristae and decreased number of microvilli,were most significant at 24 hours and then recovered gradually.The mitochondrial average area and average perimeter were increased and the mitochondrial numerical densitv was decreased gradually along with the reperfusion.At 24,36,48 hours,the mitochondrial average area and average perimeter in NA group were significantly greater than those in HA group(t=-3.566,-7.780,-4.730,-4.610,-2.599,-5.730,P＜0.05).The average numerial density of mitochondia in NA group was significantly less than that in HA group at 36,48 hours(t=-4.619,4.000,P＜0.05).The incidence rate of biliary complications in HA group is significantly lower than that in NA group(x2=4.286,P＜0.05).Conclusions Hepatic artery reconstruction in rat with OLT has an protective effect on the uhrastructure of intrahepatic biliary epithelial cells after ischemia reperfusion.It is beneficial to the recovery of intrahepatic bile duct epithelial cells and can reduce the incidence rate of biliary complications.

Lactose was shown to no less competent than Isopropyl-?-D-thiogalactoside (IPTG) in inducing the expression of the ENHANCIN coding gene from Helicoverpa armigera granulosis virus in Eswcherichia coli BL21 (DE3) regulated by a T7 promoter, since the lactose induction could lead to an ENHANCIN band no smaller than the one in IPTG induction on the SDS-PAGE gel. This would decrease the cost of the large-scale ENHANCIN production. The lactose concentration was optimized at 2.2% - 2.5% (w/v) . Different treatments on the lactose sterilization showed that lactose steam- sterilized in 116. 5℃ for 15min could lead to the ENHANCIN production. The convenience and the relatively low cost in its" operation could further decrease the cost of the ENHANCIN production.

Objective To investigate the clinical efficacy of atlantoaxial pedicle screw fixation plus bony fusion in treatment of traumatic upper cervical instability.Methods From October 2009 to August 2013,29 patients with traumatic upper cervical spine instability were treated with posterior atlantoaxial pedicle screws.The patients underwent autografting (n =19) and allografting (n =10) for spinal fusion.Surrcal outcomes were recorded including intraopcrativc blood loss,operation time,with or without nerve,blood vessel and spinal cord injury,wound healing and bone fusion rate.Results All operations were completed smoothly with operation time of 110 minutes (range,85-135 minutes) and blood loss of 150 ml (range,80-500 ml).At the follow-up of 10 months to 5 years (mean 18 months),bony fusion was detected for all the patients.Postoperative radiographs verified all patients were bony fusion with satisfactory cervical spine stability.No complications of reduction loss,fixation failure,and spinal cord or vertebral artery injury were observed except for 1 patient with low viruleut infection and 2 with delayed wound healing.Conclusion Single posterior atlantoaxial pedicle screw fixation provides security and reliable stability in treatment of upper cervical instability,however wound healing problems should be taken seriously.

This study was aimed to establish a fast determination method of main components in honey. Honey samples from difference production bases were used as study objects. Transmission and reflection spectra of different honey samples were collected with the Fourier transform near infrared spectrometer. The main components in honey (moisture content, fructose content, glucose content and reducing sugar content) were detected by the near infrared quantitative analysis technique. The near infrared quantitative analysis models of moisture content, fructose content, glucose content and reducing sugar content in honey were established by the partial least squares (PLS). The results showed that the correlation coefficient (r) of the moisture content, fructose content, glucose content and reducing sugar content in honey were 0.997 25, 0.973 90, 0.927 94 and 0.952 68, respectively. The root mean square error of prediction (RMSEP) were 0.165 (%), 0.564 (%), 1.300 (%) and 1.270 (%), respectively. It was concluded that determination of main components in honey by the near-infrared spectroscopy technology was a fast and nondestructive determination method with high accuracy, which can be used in the quantitative detection of main components in honey.

Objective To observe and compare the curative effects of zoledronic acid (ZA) combined with radiotherapy and ZA combined with chemotherapy in the treatment of bone metastasis of non-small cell lung cancer (NSCLC). Methods Seventy-eight patients with NSCLC bone metastasis treated by radiotherapy or chemotherapy were taken in our hospital from January 2010 to June 2014, including 39 cases of ZA combined conventional fractionation radiotherapy (radiotherapy combined group), and 39 cases of ZA combined with chemotherapy (paclitaxel liposome + cisplatin) (chemotherapy combined group). Each group had 39 cases. WHO objective evaluation standard, efficacy evalulation of solid tumor metastasis and curative effect standard grading of pain, anticancer agent toxicity classification standard, Karnofsky standard were used for evaluating and analyzing the patients with primary lung tumor, bone metastasis, degree of pain, adverse reactions and functional status (once before and after the treatment). Results The efficiency rate of primary lung tumor, the efficiency rate of bone metastasis, the total effective rate of pain relief and the improvement rate of functional status (Karnofsky score increased by 10 points or more)in the radiotherapy combined group and chemotherapy combined group were 82.05 % (32/39) vs. 79.49 % (31/39), 48.72 % (19/39) vs. 51.28 %(20/39), 82.05 % (32/39) vs. 84.62 % (33/39), 66.67 % (26/39) vs. 71.79 % (28/39) respectively, and the differences were not statistically significant (the values of x2 were 0.224, 0.237, 0.195, 0.259 respectively, all P> 0.05); Although the two groups showed low-grade fever, bone marrow suppression, esophagitis, liver and kidney damage, gastrointestinal reactions and other adverse reactions, the adverse reactions of two groups were close to [28.21 % (11/39) vs. 30.77 % (12/39)] (x2 = 0.314, P> 0.05). Fortunately, these reactions were controlled well after symptomatic treatment. Conclusion ZA combined with radiotherapy or chemotherapy is a safe and effective way for bone metastasis of NSCLC, which should be taken based on the individual condition of the patients.

Objective To explore the influence of Azithromycin on helper T lymphocyte cell(Th)1/Th2 in peripheral blood of children with bronchitic asthma.Methods Twenty-four asthmatic children and 20 healthy children were selected.Peripheral blood mononuclear cells (PBMC) were isolated from venous blood and made into cells suspension in aseptic condition.0.2 mg/L,0.1 mg/L,0.05 mg/L and 0 mg/L Azithromycin were added into the cultures in asthmatic group.The control group was not interfered with Azithromycin.The supernatant was collected after 48 h.The levels of IFN-?,IL-4 and IL-10 in the supernatant were determined by enzyme-linked immunosobent assay(ELISA).SPSS 11.5 software was used to analyze data.Results 1.The level of IL-4 produced from PBMC of asthmatic group was significantly higher than that of control group(P0.05).2.Azithromycin 0.1 mg/L more promoted the secretion of IL-4 than the other 3 concentrations(Pa0.05).3.Azithromycin 0.2 mg/L and 0.1 mg/L more increased the level of IL-10 than the control group(P0.05).Conclusions The routine drug level of Azithromycin(0.1 mg/L) had no effects on the imbalance of Th1/Th2 of asthmatic children,but could modulate the immunological function by up-regulating the level of IL-10.
