BACKGROUND: Migraine is usually located in the course of Shaoyang channel, and the curative effect of treatment with methods of treating Shaoyang disease by dispersing and dispelling wind (DW) as well as relieving pain (RP) on migraine is prominent, but how about the effects of these two ways on thrombogenesis in vitro and the function of platelet aggregation (PA)?OBJECTIVE: To probe into the effect of treatment of Shaoyang disease and methods of DW and RP on thrombogenesis in vitro and function of PA throughthe experiments of thrombogenesis in vitro and function of PA in rats, and investigate the compatible significance of DS and DW as well as RP through formula compatible experiment.DESIGN: Completely randomized grouping design and controlled trial.SETTING: Department of Prescription, College of Basic Medical Sciences,Heilongjiang University of Chinese Medicine.MATERIALS: The experiment was conducted in the Laboratory of Department of Prescription, Heilongjiang University of Traditional Chinese Medicine from March to August 2000. Sixty healthy adult Wistar rats were randomly divided into 6 groups: Normal control group, Shaoyang treatment group (group Ⅰ ), DW and RP group (group Ⅱ ), high-dose and whole-prescription group (group Ⅲ), low-dose and whole-prescription group (group Ⅳ), and positive control group with 10 rats in each group.METHODS:① Positive control group:Gastric perfusion of 0.034 g/mL compound divaside slice suspension (made by Harbin Second Biochemical Pharmacy co., Ltd) was given to rats (0.39/kg); Group Ⅲ and Ⅳ (ingredients: Chaihu 20 g, huangqin 10 g, banxia 15 g, gancao 10 g, chuanqiong 20 g, tianma 15 g, xixin 5 g, quanxie 5 g, wugong 5 g): Gastric perfusion of 1.5, 0.75 g/mL of complete prescription was given to rats (17.40, 8.70 g/kg);Group Ⅰ (ingredients: Chaihu 20 g, huangqin 10 g, banxia 15 g, gancao 10 g) and group Ⅱ (ingredients: Chuanqiong 20 g, tianma 15 g, xixin 5 g, quanxie 5 g, wugong 5 g): Gastric perfusion of 0.75 g/mL agents of treatment with DS and DW wind antidyne was given to rats as 8.70 g/kg; Normal control group: Gastric perfusion of normal saline of the same volume wasgiven to rats.Intervention on rats of all groups lasted 12 days.② Experiment of thrombogenesis in vitro: The cephalic artery of one side was seperated 2 hours after the last time of administration. The distal part was deligated, the blood current in proximal part was blocked with bulldog clamp and the arterial cannula was inserted into the cephalic artery. Loosened the bulldog clamp, blood of 1.8 mL was collected and put into the rotary ring of thrombogensis meter to rotate for 15 minutes at 17 r/min,and then poured the thrombus, measured the length and humid weight of thromb. After that,dried the humid thromb and measured the dry weight.③ Determination of PA:The packing fraction (PF) in the 1st and 5th minutes as well as the maximal packing fraction (MPF) and assembling inhibition ratio of platelet-rich plasma within 5 minutes were recorded with test.MAIN OUTCOME MEASURES: Effect of treating Shaoyang disease nephelometry.④ Differences of measurement data were compared with tand methods of DW as well as RP on thrombogenesis in vitro and the function of PA.RESULTS: A total of 60 rats were involved in the analysis of results. ①The length, humid weight and dry weight of thrombogenesis in vitro in group Ⅲ and Ⅳ, positive control group and group Ⅱ were obviously lower than those in group Ⅰ (P ＜ 0.05). ② The PF in 1st, 5th minute and the maximal aggregathe normal control group (P ＜ 0.05-0.01); The humid weight and dry weight of thromb in group Ⅳ were significantly lower than those in tion (MA) of blood platelet in rats of each group were significantly lower than those in the normal control group (P ＜ 0.05-0.01), and the curative effect on rats in the positive control group, group Ⅲ and Ⅳ as well as group Ⅱ were better than that in group Ⅰ.CONCLUSION: There are no significant effects of dispersing thrombogenesis in vitro and inhibiting PA by only treating Shaoyang disease. The effect of combined prescription of DW and RP as well as treatment of Shaoyang disease are obviously enhanced.

Hepatitis B virus surface antigen with mutation on site 145 may cause omission in detection of hepatitis B virus with HBsAg diagnostic reagent. Monoclonal antibody against this mutation was obtained through hybridoma technique. The sub-class of the monoclonal antibody was determined to be IgG1(? type, the titer is 1∶9?104), and the monoclonal antibody has no cross-reaction to other hepatitis virus. The method of AC-ELISA which was established with monoclonal antibody and polyclonal antibody showed high analysing susceptibility for HBV mutant samples.

ObjectiveTo investigate the development of apoptosis during ischemia/reperfusion (IR) injury and acute rejection, and to explore the significance of apoptosis in the Graft Mesenteric Lymph Node (GALT) in a rat heterotopic small bowel transplant (SBT) model.MethodsSBT was performed in F344/N rats with either freshly harvested or preserved (4 h, in ringer lactate solution at 4 ℃) syngeneic and allogeneic (Wistar/A-F344/N) grafts. Bowel and GALT samples were collected 2 h after reperfusion and on small bowel transplant postoperative days (POD) 1, 4, and 7. Histopathology assessment of the graft and GALT were prepared for hematoxylin-eosin (H&E) staining. Apoptosis was detected by the TUNEL and the electron microscope. ResultsThe number of apoptotic cells 2 h after reperfusion increased profoundly in association with preservation. After a significant decrease on POD 1, the apoptotic cells rose again between POD 3 and 7 only in allogeneic grafts. On the other hand, the apoptotic cells in allogeneic GLAT markedly increased from POD 1 to day 3; at that time point, neither histological findings of rejection nor increase in apoptotic crypt cells were present in the graft jejunum. ConclusionIR injury and acute rejection may both induce extensive apoptosis. The graft jejunum distinct second increase in apoptosis may be an early and specific sign of acute rejection. Apoptosis of GLAT cells was well correlated with and ahead of progression of acute rejection.

Objective To study the molecular identification method of Sporothrix schenckii based on the nucleotide sequences in internal transcribed spacer region 2 of ribosomal DNA (rDNA) genes. Methods Species-specific primers were used to amplify the internal transcribed spacer region 2 of rDNA of 22 clinical isolates of Sporothrix schenckii and 12 strains of dematiaceous fungi. Totally 11 strains of Sporothrix schenckii were sequenced and analyzed, in which 1 strain came from the US and the others were isolated from different areas in China. A pair of species-specific oligonucleotide primers (SSP) were designed based on the ITS2 sequence. With the species-specific primers, rDNA of Sporothrix schenckii and dematiaceous fungi were amplified by PCR. Results Sequencing and analysis showed that internal transcribed spacer region 2 of rDNA gene was conservative in Sporothrix schenckii. A 300 bp fragment was obtained from 22 strains of Sporothrix schenckii, but not from the other species. Conclusions This method is specific, sensitive and reliable for the identification of Sporothrix schenckii and could be used for clinical molecular diagnosis.

Objective To investigate the clinical application of rhythmic abdominal lifting and compression cardiopulmonary resuscitation (ALC-CPR) in cardiac arrest (CA) patients with conventional cardiopulmonary resuscitation (CPR) contraindication (chest rib fracture, chest trauma, etc.).Methods The clinical data of patients with CA in emergency department of Hefei Second People's Hospital from June 2015 to December 2016 were analyzed retrospectively, and the patients with weights 40-150 kg and CA≤20 minutes, and resuscitated with ALC-CPR were selected. The vital signs and blood gas analysis indexes of patients before resuscitation and 30 minutes after return of spontaneous circulation (ROSC, after successful resuscitation) were recorded.Results A total of 19 patients with CA were treated with CPR-LW1000 type ALC-CPR apparatus for resuscitation, and with 12 males, 7 females; the age ranged from 43 to 87 years, and the average age was (70.32±13.49) years; there were 4 cases of heart disease, and 15 cases of non-heart disease. Compared with before resuscitation, the heart rate [HR (bpm): 115.05±21.70 vs. 0], mean arterial pressure [MAP (mmHg, 1 mmHg = 0.133 kPa): 66.05±11.69 vs. 0], pulse oxygen saturation (SpO2: 0.928±0.057 vs. 0.417±0.118), pH value (7.05±0.23 vs. 6.80±0.28), arterial oxygen partial pressure [PaO2 (mmHg): 65.42±19.11 vs. 42.42±10.78], HCO3- (mmol/L: 19.22±2.77 vs. 17.18±3.76) were significantly improved after successful resuscitation (allP < 0.05), and arterial blood carbon dioxide partial pressure (PaCO2) was decreased after successful resuscitation (mmHg: 53.72±13.23 vs. 57.66±14.86,P > 0.05).Conclusion Rhythmic ALC-CPR has obvious clinical value for CA patients with conventional CPR contraindication.

Sodium phenylacetate can induce differentiation of tumor cells and has been approved as a drug for the treatment of adults with cancer. In order to explore the immunological mechanism of its antitumor effect, the influence of sodium phenylacetate on HLA class I and II molecule expression in various human tumor cell lines, including breast adenocarcinoma (MCF-7.MUA-453), gastrocarcinoma(MKN-28,MKN-45), ovarian cancer(3AO) and cervical cancer(Hela), was studied with ELISA. The result showed that HLA class II molecule was absent from the surface of MCF-7 cells, but they could be induced after 7 days of continued treatment with sodium phenylacetate. Sodium phenylacetate was found to increase HLA class I molecule expression on the surface of MCF-7 cells, HLA class 1 and II molecule expression on the surface of MDA-453、 MKN-28、 MKN-45、 Hela and 3AO cells. The effect of sodium phenylacetate on HLA class I molecule expression in tumor cells is dose-and time-dependent.
