Objective To assess the value of procalcitonin( PCT) in anti-infective therapy by observing PCT concentration change in therapy. Methods Sixty-eight patients with bacterial infection meet the diagnostic criteria were divided into effective group and invalid group,the PCT level on day 1,day 3,day 5 and day 7 were observed respectively. Results PCT concentrations of two groups showed no sig-nificant difference on day 1. The PCT level of effective group gradually declined and PCT level of invalid group gradually rised with significant difference on day 3,day 5 and day 7(P<0. 05). Conclusion PCT level that is positively correlated with inflammation of infectied patients, which can be used as an effective indicator to optimize antibiotic therapy.

This study was aimed to find the optimal conditions for seed propagation of Fritillaria cirrhosa in the plateau region in order to summarize the best sowing time and method of artificial propagation. Seeds were stored in appropriate environment. After the seeds matured, the seedbed of F. cirrhosa was treated with cattle dung humus and small shed. The results showed that early March is the best sowing time and cattle dung humus with a thickness about 1 cm is the best coving for propagation of F. cirrhosa; the growing period of film propagation (FP) is about 160 days each year compared with that of control about 50-60 days, respectively. It was concluded that the propagating seeds in plastic greenhouses by using cattle dung humus as planting substrates, using sunshade nets for shading and keeping humidity by spraying can effectively prolong the growing period, improve the retention rate of annual bulbs and the production of F. cirrhosa.

Objective To investigate the distribution and effect of class Ⅰ integron in 40 strains of clinical multi-resistant Enterobacter cloacae. Methods Kirby-Bauer method was used to analyze the drug resistance of 40 strains of multi-resistant Enterobacter cloacae and the drug resistance gene was analyzed by polymerase chain reaction (PCR). Results 28 strains (70.0%) of 40 clinical isolates were observed to contain class Ⅰ integron. Drug resistance test showed their resistance rate to 10 kind of an-tibaeterials as follow: 7.5% to imipenem, 5.0% to meropenem, 75.0% to piperacillin-tazobactam,55.0% to amikacin, 12.5% to cefepime, 52.5% to ceftazidime, 55.0% to cefotaxime, 90.0% to ceftriaxone;81.8% to ticarcillin-clavutanic acid, and 85.0% to ciprofloxacin. Conclusion This study shows that the resistance situation of Enterobacter cloacae isolates is very serious, and class Ⅰ integron may play an important role in the muhidrug resistant mechanism.

Objectives:The present study in vestigated the presence and significance of serum antibody against human myocardial mitochondria in patients with virus myocarditis (VMC) and dilated cardiomyopathy (DCM). 　　Methods:The human myocardial mitochondtia were used as antigen to detect serum autoantibody by immuno-dot blot in 29 VMC patients,24 DCM patients,33 patients with other cardiac (OCD) and 20 healthy blood donor (HBD).The antigen molecular weight was detected by Western blot. 　　Results:①Positive autoantibody against human myocardial mitochordria was found in 41.4% in VMC and 41.7% in DCM patients,which were much higher than 6.1% in OCD or 0% in HBD patients.②Cardiac troponin T was elevated in 43.8% of autoantibody-positive VMC and DCM patients,which was much higher than 12.0% in autoantibody-negative VMC and DCM patients (p＜0.05).③The antigen molecular weight of human myocardial mitochondria was 30KD. 　　Conclusions:①The presence of autoantibody against supports that concept that is responsible for the development of VMC and DCM.Autoantibody is one of the factors that give rise to cardiac injury.The antibody detection may serve as a diagnostic index for VMC and DCM.②The specific antigen is probably human myocardial adenine nucleotide translocator.

To analyze the compatibility regularity of compound traditional Chinese medicine (TCM) patents for treating dyslipidemia, and provide basis for the clinical development and research of new TCM for treating dyslipidemia. Totally 243 compound traditional Chinese medicine patents for treating dyslipidemia were collected from the national patent database from September 1985 to March 2014 and analyzed by using drug frequency, association rules, complex network and entropy method of Traditional Chinese Medicine Inheritance System (V1.1). The commonest single medicine in the treatment of dyslipidemia is Crataegi Fructus 109 (44.86%). The commonest pair medicine is Crataegi Fructus-Salviae Miltiorrhizae Radix et Rhizoma 53 (21.81%). The commonest corner drug is Crataegi Fructus-Cassiae Semen-Polygoni Multiflori Radix 25 (10.29%). The common prescriptions on basis of association rules are Prunellae Spica-->Salviae Miltiorrhizae Radix et Rhizoma (0.833), Rhei Radix et Rhizoma, Alismatis Rhizoma-->Polygoni Multiflori Radix (1.00), Salviae Miltiorrhizae Radix et Rhizoma, Cassiae Semen, Alismatis Rhizoma-->Polygoni Multiflori Radix (0.929). The core drugs based on complex networks are Salviae Miltiorrhizae Radix et Rhizoma and Crataegi Fructus. The new prescriptions extracted by entropy method are Atractylodis Macrocephalae Rhizoma-Glycyrrhizae Radix et Rhizoma-Platycladi Semen-Stephaniae Tetrandrae Radix; Citri Reticulatae Pericarpium-Poria-Coicis Semen-Pinelliae Rhizoma. This study shows the regularity in the compatibility of compound TCM patents treating dyslipidemia, suggesting that future studies on new traditional Chinese medicines treating dyslipidemia should focus on the following six aspects: (1) Single medicine should be preferred: e. g. Crataegi Fructus; (2) Pair medicines should be preferred: e. g. Crataegi Fructus-Salviae Miltiorrhizae Radix et Rhizoma; (3) Corner drugs should be preferred: e. g. Crataegi Fructus, Cassiae Semen, Polygoni Multiflori Radix; (4) The compatibility among drugs shall be given attention, and highly correlated drugs should be preferred: e. g. Prunellae Spica, Salviae Miltiorrhizae Radix et Rhizoma; Rhei Radix et Rhizoma, Alismatis Rhizoma, Polygoni Multiflori Radix; Salviae Miltiorrhizae Radix et Rhizoma, Cassiae Semen, Alismatis Rhizoma, Polygoni Multiflori Radix; (5) Core drugs should be dominant and compatible, e. g. in the digestion catharsis method, the core drugs is Crataegi Fructus and compatible with Salviae Miltiorrhizae Radix et Rhizoma; (6) Application of new prescriptions: Atractylodis Macrocephalae Rhizoma, Glycyrrhizae Radix et Rhizoma, Platycladi Semen, Stephaniae Tetrandrae Radix; Citri Reticulatae Pericarpium, Poria, Coicis Semen, Pinelliae Rhizoma.
