Objective To investigate the effect of intravenous thrombolytic therapy with urokinase on the neurological function and the concentration of serum matrix metalloproteinase 9 (MMP-9) in the patients with acute cerebral infarction.Methods The patients with acute cerebral infarction were divided into the experimental and control groups.The experimental group included 27 patients who were complied with thrombolytic criterion within 4.5 hours after stroke and were firstly treated by intravenous thrombolytic therapy with urokinase by 100 million units after 24 h and 300 mg aspirin by oral.The control group included 27 cases that were directly administrated by 300 mg aspirin 4.5 hours later after stroke.After 24 h,the two groups were administrated with other same conventional treatments such as neurotrophy,improvement of microcirculation,and control of blood-fat.The neurological function and dynamic concentration of serum MMP-9 were observed before treatment and after treatment.Results After treatment,the neurological deficit evaluation score in both groups was gradually reduced with the treatment time,and the neurological deficit evaluation score in the experimental group was significantly lower than that in the control group at the 1 st,3rd,and 14th day,respectively[(10.97 ± 1.53) Score vs (15.67 ±1.78)Score,t =8.35,P =0.03;(8.15 ± 1.40) Score vs(12.72 ± 3.31) Score,t =6.62,P =0.03; (5.87 ± 1.03) Score vs (11.92 ±2.05) Score,t =13.70,P =0.01].After treatment,the concentration of serum MMP-9 in both groups was reduced with the treatment time,and serum MMP-9 in the experimental group was significantly lower than that in the control group at the 1st,3rd,and 14th day,respectively[(282.84 ±37.51) ng/ml vs (316.90±36.75)ng/ml,t =3.37,P =0.00;(309.11±37.71)ng/mlvs (348.39 ±15.26) ng/ml,t =5.02,P=0.04;(264.68±31.91)ng/ml vs (302.81 ±36.30)ng/ml,t =4.10,P =0.03].Conclusions Intravenous thrombolytic therapy with urokinase can effectively reduce the neurological deficit and the produce of MMP-9 in patients with acute cerebral infarction.

Matrine is a traditional Chinese medicine extraction which can inhibit the proliferation, migration and apoptosis of tumor cells. Cell signal transduction affects the tumor biological behavior and growth condition. Except for the widely research of MAPK, JAK-STAT, NF-κB signal transduction pathways, the latest signaling pathways about matrine are Wnt/β-catenin signaling pathway and mTOR signaling pathway. These pathways are mainly activated by the phosphorylated key proteins to alleviate inflammatory reaction and inhibit the growth of tumor cells and tumor biological behaviors. The research of matrine by cell signaling pathways can provide molecular targeted therapy with theoretical basis. The relationship among different signaling pathways related to the anti-tumor effect of matrine is worth studying deeply in the future.

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.

Objective To observe and explore the effects of transparent cap-fitted colonoscope combined with carbon dioxide injection on the cecal intubation time and detection of colonic polyps during enteroscopy. Methods 216 patients underwent colonoscopy from January 2014 to June 2016 were selected and randomly divided into A, B, C groups according to random number table, 72 cases in each. Group A with transparent cap-fitted colonoscopy, group B with CO2 injection before colonoscopy, and group C combined with the above two methods and then underwent colonoscopy, cecal intubation time and colonic polyp detection rate were compared among the three groups during the inspection. Results A, B, C groups with cecal intubation ratio showed no significant differences (95.8% vs 90.3% vs 98.6%) (χ2 = 5.34, P = 0.069); the sequence of mean cecal intubation time was group Cgroup A>group B (38.9% vs 34.7% vs 23.6%) (χ2 = 4.10, P = 0.129). The sequences of visual analogue scale score after 10 min [(4.35 ± 0.62) vs (4.88 ± 0.85) vs (5.57 ± 1.05)] and 30 min [(3.04 ± 0.37) vs (3.30 ± 0.56) vs (4.41 ± 0.84)] of coloscope withdraw were both group C

Objective To evaluate the effects of dexmedetomidine combined with subanesthetic dose of ketamine on the emergence agitation in the patients undergoing thoracotomy.Methods Eighty ASA physical status Ⅱ or Ⅲ patients,aged 55-75 yr,weighing 50-75 kg,scheduled for elective esophageal cancer resection,were randomly divided into 4 groups (n =20 each) using a random number table:normal saline group (NS group),dexmedetomidine group (group D),subanesthetic dose of ketamine group (group K),and dexmedetomidine combined with ketamine group (group DK).In DK and K groups,ketamine 0.5 mg/kg was injected intravenously (within 1 min) at 10 min before the end of the operation.In DK and D groups,dexmedetomidine 0.5 μg/kg was infused intravenously over 10 min starting from 10 min before the end of operation.In group NS,the equal volume of normal saline was infused intravenously over 10 min starting from l0 min before the end of operation.The emergence time,extubation time,duration of ICU stay,occurrence and degree of agitation,and development of cardiovascular events and hypoxemia within 24 h after operation were recorded.Ramsay sedation scores were recorded before induction of anesthesia (T1),immediately after completion of administration at the end of surgery (T2),and at 0,5,10 and 30 min after extubation (T3-6).Results There was no significant difference in the emergence time,extubation time,and duration of ICU stay between the four groups.Compared with group NS,Ramsay sedation scores were significantly increased at T3-6,the incidence and degree of agitation were decreased,and the incidence of cardiovascular events and hyoxemia was decreased in D,K and DK groups.Compared with D or K group,Ramsay sedation scores were significantly increased at T3-6,the incidence and degree of agitation were decreased,and the incidence of cardiovascular events and hyoxemia was decreased in group DK.Conclusion Dexmedetomidine combined with subanesthetic dose of ketamine can prevent the emergence agitation in the patients undergoing thoracotomy,which provides better efficacy than either alone.

Objective To evaluate the effect of using serf-designed facial support in prone position for patients after vitrectomy and silicone oil tamponade. Methods 100 patients with vitrectomy and sili-cone oil tamponade were randomly divided into the experimental group and the control group with 50 pa-tients in each group. The self-designed facial support in prone position was used in the experimental group, while the routing nursing measure was used in the control group. The ocular adverse effect and re-lapse rate were compared between the two groups. Results The incidence rate of corneal edema, in-creased intraocular pressure and retinal redetachment in the experimental group was higher than those in the control group, the time of keeping position in the experimental group was longer than that in the con-trol group. Conclusions Self-designed facial support in prone position can decrease discomfort and pain caused by compulsive position, reduce the incidence of complications, improve retinal attachment and increase the successful rate for the patients with vitrectomy and silicone oil tamponade.

Objective To report a case of Majocchi's granuloma induced by var. raubitschekii of Trichophyton rubrum, and to evaluate the relationship between deep and superficial fungal infection with genotyping technique. Methods The patient underwent physical, pathological and mycologic examination,which included microscopic observation, fungal culture, and urease reaction. The sequence of intertranscribed spacer (ITS) of rDNA was analysed by PCR and sequencing. Isolates from affected toes and tissue as well as one reference strain and six clinical strains of T. rubrum, were subjected to analysis of the tandem repeat subelement(TRS-1) in nontranscribed spacer(NTS)of rDNA by PCR. Results A 48-year-old female patient presented with a 2-month history of red papules and nodular lesions on the back, buttock and thigh,as well as a 3-year history of onychomycosis which had become more severe after a liver transplantation 9 months before. Pathological and mycologic examinations confirmed the diagnosis of Majocchi's granuloma. The pathogen was identified as var. raubitschekii of T. rubrum by microscopic examination, fungal culture, positive urease reaction and the sequence of ITS. As shown by the amplications of TRS-1 of NTS, the genotypes of strains from affected nails and tissue were identical, but differed from those of other clinical strains of T.rubrum. Conclusions There is a polymorphism in TRS-1 of rDNA NTS of T. rubrum, with the genotypes of isolates from affected nails and tissue being identical, which suggests they are of the same origin.

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.
