Objective To observe the effects of road transport on hematological and biochemical parameters in New Zealand rabbits.Methods A total of 12 healthy New Zealand rabbits were selected for 2 h road transport.Blood samples were collected at 0, 24, 48, 72 and 96 h after transport, respectively.White blood cells (WBC), red blood cells (RBC), hemoglobin (HGB), hematocrit (MCV), mean erythrocyte hemoglobin content (MCH), mean erythrocyte hemoglobin concentration (MCHC) and platelets (PLT) were measured using a blood analyzer.Blood alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (ALB), total protein (TP), urea nitrogen (UREA), creatinine, uric acid (UA), triglycerides (TG), total cholesterol (COHL), glucose (GLU), hypersensitive C-reactive protein (CRP), α-amylase (AMYL), and creatine kinase (CK) were detected by an automatic biochemical analyzer.Results Compared the parameters before and after transport, The WBC count was increased first (P< 0.05 or P < 0.01) and then decreased after transport, the levels of RBC, HGB, HCT and PLT were decreased first (P< 0.05 or P < 0.01) and then increased after transport, and MCV was significantly high at 96 h after transport (P< 0.05).Among the clinical biochemical parameters, ALT, AST and BUN were firstly elevated (P< 0.05 or P < 0.01) and then decreased.TP, ALB as well as CREA and TG were firstly decreased (P< 0.05 or P < 0.01) and then increased.GLU was significantly low at 24 h after transport (P< 0.05).All parameters except MCV at 96 h after transport were not significantly different from those before transport.Conclusions Changes of blood routine, liver and kidney function indexes, lipid metabolism indexes, glucose metabolism index and creatine kinase index are observed in the New Zealand rabbits after 2-hour road transportation, and all the indicators except MCV return to pre-transport levels within 96 h.

Reuse of waste oil in cooking has been the social concern for long time, but until now there is no reliable method to identify the gutter oil.In this work, based on the generation of long-chain aliphatic aldehydes in the refinement of gutter oil, gutter oil and adulterate cooking oil were identified by determining hexanal, heptanal, octanal, nonanal and decanal in oil sample with high perfomance liquid chromatography (HPLC) method using O-(3-(9H-carbazol-9-yl)propyl)hydroxylamine as the fluorescent derivative reagent.At first, 10 μL of oil sample was dissolved in 200 μL of isopropanol, then reacted with O-(3-(9H-carbazol-9-yl)propyl)hydroxylamine to form the stable derivatives, extracted with acetonitrile and injected into HPLC for analysis.The derivatives were separated on a C18 column within 15 min with ACN-H2O (90∶10, V/V) as mobile phase.The fluorescence detector was set at λex/λem=292 nm/348 nm.The linear range of 5 kinds of long-chain aliphatic aldehydes was 0.01-1.00 μmol/L with limit of detection (LOD, S/N=3) of 0.05-0.10 nmol/L, and the spiked recoveries were 95.6%-101.4%.The results showed that the edible oils obtained from supermarket almost had no hexanal, heptanal, octanal, nonanal, decanal, but these aldehydes increased significantly in gutter oil.Thus the 5 kinds of long-chain aldehydes could be used as the indictor of gutter oil.Taking the advantage of good specificity, higher sensitivity, good accuracy and simplicity, the method was suitable for the rapid identification of gutter oil.

Objective:To compare the sedative effect and safety of different doses of dexmedetomidine in the patients undergoing total abdominal hyserectomy. Methods:A total of 120 patients undergoing total abdominal hysterectomy were randomly divided into four groups, different doses of dexmedetomidine groups(D1 group, D2 group and D3 group)and midazolam group(M group) with 30 pa-tients in each. Dexmedetomidine groups received intravenous pump infusion of dexmedetomidine (0. 5 μg·kg-1 ) 10 minutes before the operation, and then the different dexmedetomidine groups were received continuous infusion of dexmedetomine of different doses:D1 group of 0. 4μg·(kg·h) -1, D2 group with 0. 6μg·(kg·h) -1 and D3 group with 0. 8μg·(kg·h) -1;M group received in-travenous pump infusion of midazolam (0. 06 mg·kg-1) 10 minutes before the operation, and then with 0. 04 mg·(kg·h) -1 con-tinuous infusion. The mean arterial pressure( MAP) , heart rate( HR) , respiratory rate( RR) , oxyhemoglobin saturation( SpO2 ) were recorded at the following time points:the moment of entering the operating room(T0), the block effect of epidural anesthesia was satis-fied (T1),10 min(T2),20 min(T3)and 40 min(T4)after the drug infusion, and the end of the operation(T5), and the duration of the medicine use and the whole operation were recorded as well. The sedation degrees were evaluated with Ramsay scale, and the am-nesic scores, adverse drug reactions and patient satisfaction were recorded after the operation. Results:Compared with that of the other groups, HR of D3 group was obviously lower after T3 (P<0. 05);and after T2, HR was significantly lower than that at T0 (P<0. 05 or P<0. 01). Compared with the other groups, RR of M group was obviously lower at T3 and T4 (P<0. 05). Compared with those at T0 , the sedative effects of all the groups were much remarkable(P<0. 05 or P<0. 01);and the Ramsay score of D3 group at T3 and T4 was higher than that in D1 group or M group(P<0. 05). There were no obvious adverse reactions in the four groups. Conclusion:The use of dexmedetomidine in the patients undergoing total abdominal hyserectomy might not lead to the risk of respiratory depression as the use of midazolam, while the dose of dexmedetomidine should be less than 0. 8 μg·(kg·h) -1.

Background and purpose:TrkB,a neurotrophic tyrosine kinase receptor,serves as a potent and specific suppressor of anoikis of non-malignant epithelial cells,and induces high invasion capacity in these cells.TrkB over-expression has been associated with chemotherapy resistance and poor survival in neuroblastoma and some other highly aggressive cancers.However,the relationship of the expression of TrkB to anoikis resistance in ovarian cancer cells has rarely been reported in literature.This study investigated the expression and significance of anoikis- suppressor TrkB in OVCAR-3 ovarian cancer cells.Methods:The expression of TrkB and its ligand BDNF was evaluated in OVCAR-3 ovarian cancer cells under different culture conditions by RT-PCR and Western blot.Results: TrkB mRNA was overexpressed in multicellular spheroids(cell-spheroids,anchorage-independent culture,AIC)as compared to that in OVCAR-3 cells(adhesive-cells,adhesive culture,AC),(35.3?0.7)% versus(23.5?0.5)%;but BDNF mRNA expression was the opposite to the above situation,(41.4?0.6)% versus(32.24?0.7)%(P

By analyzing the epidemiological and clinical features of adenovirus in children with acute respiratory tract infection (ARTI), we provide a theoretical basis for early clinical diagnosis and treatment. Nasopharyngeal secretions were collected from 3480 children with ARTI, who were hospitalized at the No. 2 Hospital of Changzhou from January 2011 to December 2012. Adenovirus were detected using direct immunofluorescence assays. A total of 80 samples were positive for adenovirus (2.30%). The rate of adenovirus infection during 2011 was significantly higher than that in 2012, and the infection rate was higher in summer and autumn than in winter and spring. The infection rate was 1.14% among children aged < 1-year-old and the rates were higher among children in other age ranges. Adenovirus was found to be an important ARTI pathogen in children in Changzhou, mainly affecting children older than 1 year. ADV infections have various clinical presentations, but affected children tend to be severely ill with poor outcomes.

The efficacy of Chinese herbal formula in treating depression has been proved in many studies. In this study, six different Kaixin San formulas were compared to investigate their effects on central monoamine neurotransmitters of chronic stress rats and against depression based on their different components in plasma, in order to discuss the efficacy-comparability relationship and the possible efficacy mechanism. The classic isolation method and the chronic unpredictable mild stress (CUMS) depression model were combined to investigate the changes in contents in hippocampus and monoamine neurotransmitters (NE, DA, 5-HT) and the components of some formulas in plasma with HPLC and UPLC-Q-TOF-MSE methods. As a result, Dingzhi Xiaowan recorded in Essential Recipes for Emergent Use Worth A Thousand significantly increased the behavioral scores, NE and 5-HT contents in hippocampus and NE, DA and 5-HT contents in cortex, with the best anti-depressant effect. Dingzhi Xiaowan recorded in Complete Records of Ancient and Modern Medical Works showed a notable increase in sucrose preference and open field score in model rats, NE content in hippocampus and NE, DA and 5-HT contents in cortex, with a certain anti anti-depressant effect. Kaixin San recorded in Ishinpo showed remarkable rise in weight of model rats. NE content in hippocampus and DA content in cortex. Puxin Decoction recorded in A Supplement to Recipes Worth A Thousand Gold showed 5-HT content in hippocampus and DA content in cortex. Kaixin San recorded in Yimenfang only showed DA content in cortex. Kaixin Wan recorded in Essential Recipes for Emergent Use Worth A Thousand did not mention the antidepressant effect. According to the results, the formulas' different anti-depressant effects may be related to the different plasma components.

Objective To examine the association of urinary neutrophil gelatinase-associated lipocalin(NGAL) and interleukin 18(IL-18) with acute kidney injury (AKI) in patients after cardiac surgery. Methods Thirty-three patients undergone cardiac surgery were divided into AKI group and non-AKI group according to the AKI criteria. The Scr, urinary NGAL and IL-18 were measured at different time points. Results Nine of 33 patients (27.27%)developed postoperative AKI, and Scr concentration in AKI group reached its peak within 12-48 hours after cardiac surgery. Urinary concentrations of NGAL and IL-18 at 2 h and 4 h after cardiac surgery were significantly higher than those before operation in AKI patients (P<0.01). The urinary concentrations of NGAL at each time point and that of IL-18 at 2 h and 4 h after cardiac surgery in AKI patients were significantly higher than those in non-AKI patients. After correction by urinary creatinine, the differences of NGAL/Ucr and IL-18/Ucr ratios were still significant (P< 0.01). For concentrations of urinary NGAL, IL-18 and ratios of NGAL/Ucr, IL-18/Ucr at 2 h after surgery, sensitivities and specificities were good with cutoff values at 250 μg/L, 250 μg/mmol and 1800 ng/L, 1800 ng/mmol, respectively. Urinary concentration of NGAL at 2 h after cardiac surgery was positively correlated with Scr at 12 h postoperation in AKI group (r=0.638, P<0.05).Conclusions The incidence of AKI in patients after cardiac surgery is quite high. Urinary concentrations of NGAL, IL-18 and ratios of NGAL/Ucr, IL-18/Ucr at 2 h after cardiac surgery are the early diagnostic markers for AKI, among which urinary NGAL/Ucr is the most sensitive one.

OBJECTIVETo observe the therapeutic efficacy and safety of gonadotropin-releasing hormone agonist (GnRHa) combined Wenshen Xiaozheng Decoction (WXD) in auxiliary treating endometriosis after laparoscopy.

METHODSOne hundred and thirty-four endometriosis patients with confirmative pathological diagnosis were assigned to three groups depending on whether they would receive adjuvant therapy or Chinese medicine treatment, i.e., the control group, the observation 1 group, and the observation 2 group. The 22 patients in the control group received no adjuvant therapy after laparoscopy. The 42 patients in the observation 1 group were treated with GnRHa 3.6 mg by subcutaneous injection starting from the 1st day to the 5th day of menstruation, once per 28 days. The 70 patients in the observation 2 group were treated with GnRHa 3.6 mg by subcutaneous injection in combination with WXD starting from the 1st day to the 5th day of menstruation, once per 28 days. They also took WXD for 7 doses, one cycle per every 28 days. The treatment lasted for three to six months. Serum levels of estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and cancer antigen 125 (CA125), as well as clinical efficacy, and adverse drug reactions were observed before and after treatment.

RESULTSThere was statistical difference in serum levels of E2, FSH, or LH between the control group and the observation 1 and 2 groups (P < 0.05). There was no statistical difference in serum levels of E2, FSH, or LH between the observation 1 group and the observation 2 group (P > 0.05). There was statistical difference in the clinical efficiency among the 3 groups (P < 0.05). There was statistical difference in the pre-post difference of CA125 levels among the three groups (P < 0.01). Compared with the control group, there was no statistical difference in the pre-post difference of CA125 levels between the observation 1 group and the observation 2 group (P > 0.05). No obvious adverse reaction occurred during the treatment.

CONCLUSIONSGnRHa combined WXD showed confirmative clinical efficacy in treating endometriosis after laparoscopy. It also could lower serum levels of E2, FSH, and LH levels. So it was an ideal solution for treatment of endometriosis.
