Objective:To detect differences in results of routine biochemical indexesand serum anticoagulant heparin, explore the feasibility of plasma heparin in the emergency biochemical test in.Methods: Two hundred cases of patients in the emergency department of our hospital as the research object, peripheral venous blood samples, were installed on the ordinary drying tube and a heparin plasma in vitro, determination of 10 emergency patients in serum and plasma biochemical items using biochemical analyzer, comparative analysis of the effect of heparin plasmabiochemical test results, and to compare the two groups report time.Results: The difference of serum group and Mg2+ group, Cl-, plasma Ca2+, Cr, BUN, UA, ALT, GLU and other data is not obvious, no statistical significance, The plasma concentration of K+ group was significantly lower than serum group, serum concentration of Na+ was higher than group difference was significant, with statistical significance(t=8.167,t=4.361;P<0.05). Plasma group reported significantly less than the serum group(t=22.94,P<0.05).Conclusion: heparin sodium does not dissolve in the blood, with a strong ability for anticoagulation, emergency biochemical test can avoid the effect of blood coagulation test results, and shorten the time for patients toreport, to win the precious time, attention is needed to correct potassium ionconcentration difference test.

Object In order to identify the resources of official and unofficial plants in Rheum L.at molecular level, a random amplified polymorphic DNA (RAPD) analysis was performed. Methods The amplification program of polymerase chain reaction (PCR) was optimized. Arbitrary decamer primers of 121 based on the individual selecting method, and 64 based on the BSA method were screened. Results Four primers among all screened primers were found to be useful to amplify specific strips to the official plants of Rheum L. Conclusion This method is reliable, accurate, quick and reproducible for authenticating the official and unofficial plants of Rheum L. at molecular level. Moreover, the experiment results indicate that it is more effective to screen the primers using BSA method than using individual selecting method.

Objective To investigate the clinical characteristics of tuberculous pleurisy(TP) in children in order to provide a good solution to the diagnosis and treatment of this disease.Methods Retrospective analysis was performed on the clinical data of 113 cases confirmed with TP who were admitted to Children's Hospital of Chongqing Medical University from January 2009 to December 2014.Results Among the 113 pediatric inpatients with TP,85 cases (75.2%) were sick for less than 1 month;92.9% (105/113 cases) age ≥≥5 years old by onset;and 21.2% (24/113 cases) patients demonstrated the contact with tuberculosis ,among whom 70.8% (17/24 cases) attributed to linear relatives.The primary clinical manifestations included fever[96.5% (109/113 cases)], cough [76.1% (86/113 cases)] and chest pain[38.9% (44/113 cases)] ,with as high as 89.0% (87/109 cases) of the patients experiencing moderate or ardent fever.The positive rates of acid-fast bacilli smear and mycobacterium tuberculosis culture were 12.2% (17/139 cases) and 22.7% (15/66 cases), respectively;among the 41 patients who received pleural biopsy,40 cases (97.6%) were identified with the typical pathological changes in tuberculosis;and all 11 patients who received acid fast stain test on pleural tissues were positive to the test.Pulmonary parenchymatous lesions were revealed on CT examination in 89.1% patients(98/113 cases),82.4% (90/109 cases) of the patients had normal body temperature within a short period,and reduced effusion was revealed in 86 out of 98 patients who received repeated chest imaging examinations.Conclusions TP in children has acute onset typically, and the diagnosis of TP in children is more difficult than in adults,requiring considering multiple factors.Contact history with tubercular patients, etiological examination, pleural biopsy and chest CT are essential for the diagnosis of this disease.

Objective :To properly understand the bacterial distribution and susceptibility to antibiotics in thesinus of nasal sinusitis. Method:The mucosal and secretione in sinus were taken from 135 patients who sufferedwith single nasal sinusitis, by functional endoscopic sinus surgery, were cultured for bacteria. Meanwhile the an-timicrobial susceptibility was determined for ordinary antibiotics. Result: The bacterial growth was present in88.15 % of cases ,mixed bacterial growth was present in 52.10 % of all bacterial ,anaerobe growth was present in39.06%00 of all bacteria. the susceptibility to penicillin was in 53.12%0 of all bacteria and cefaolin was in 87.50%.The susceptibility to metronidazole was in 94.67 % of all anaerobes. Conclusion:We think the method that peni-cillin in combination with streptomycin and metronidazole, sufameth oxazole united with metronidazole, cefaolinadded metronidazole were effective in nasal sinusitis treatment before the antimicrobial susceptive examinationhad been done.

Objective:To investigate the possible role of NKT cells in unexplained recurrent spontaneous abortion by measuring the NKT cell numbers,maturity and cytokine secretion of the placenta of mice with unexplained recurrent spontaneous abortion.Methods:Normal pregnancy model in hybrid by feeding CBA / J and BABL/C in a cage,and the model of unexplained recurrent spontaneous abortion was established by feeding CBA / J and DBA2/J in a cage.The number of NKT and CD3~+T cells was determined by flow-cytometry;Th1/Th2-relative cytokines were assayed by ELISA and T-bet expression was determinded by fluorescence quantitative PCR.Results:There was not significant change of CD3~+ T cells when compared between normal pregnancy and unexplained recurrent spontaneous abortion group (P>0.05).In the course of normal pregnancy,the IFN-γ secreted by placenta lymphocytes decreased gradually,accompanied by the decline of NKT cell number and the proportion of mature cells;whereas in the course of unexplained recurrent spontaneous abortion,it was on the opposite.There was significant difference of T-bet mRNA expression between the two groups.T-bet mRNA expression was related to the proportion of mature NKT cells or placenta IFN-γ secretion by lymphocytes.Conclusion:Unexplained recurrent spontaneous abortion may be related to NKT cells disorders,NKT cells are of low-mature proportion and inadequate secretion of IFN-γ during early pregnancy,whereas are shown high-mature proportion and excessive secretion of IFN-γ during latter pregnancy;the anomaly of T-bet mRNA expression may be one of the factors leading to NKT cells disorder.
