Drugs are exogenous compounds for human bodies, and will be metabolized by many enzymes after administration. CYP450 enzyme, as a major metabolic enzyme, is an important phase I drug metabolizing enzyme. In human bodies, about 75% of drug metabolism is conducted by CYP450 enzymes, and CYP450 enzymes is the key factor for drug interactions between traditional Chinese medicine( TCM) -TCM, TCM-medicine and other drug combination. In order to make clear the interaction between metabolic enzymes and TCM metabolism, we generally chose the enzymatic activity as an evaluation index. That is to say, the enhancement or reduction of CYP450 enzyme activity was used to infer the inducing or inhibitory effect of active ingredients and extracts of traditional Chinese medicine on enzymes. At present, the common method for measuring metabolic enzyme activity is Cocktail probe drugs, and it is the key to select the suitable probe substrates. This is of great significance for study drug's absorption, distribution, metabolism and excretion (ADME) process in organisms. The study focuses on the interaction between TCMs, active ingredients, herbal extracts, cocktail probe substrates as well as CYP450 enzymes, in order to guide future studies.

Objective To observe the changes of immunological parameters and the effects of intravenous immunoglobulin (IVIG) in children with idiopathic thrombocytopenic purpura (ITP),schonlein-Henoch purpura(HSP) and mucocutaneoas lymph node syn-drome(kawasaki disease, KD).Methods T cell subsets and serum immunoglobulins and complements were measured with the flow cytometry and enhanced trubidimetric immunoassay. Routine therapy combined with IVIG. Results CD3+ CD4+ T cells were de-creased in children with ITP accompanied by increased serum IgG;Serum IgA and CD3+ T cells were increased in children with HSP; CD3+ CD8+ T cells were decreased in children with KD. Clinical features were markedly improved after treatment with IVIG. It was noted that the incidence of damage to coronary artery decreased after the use of IVIG. Conclusions T cell subsets, serum immunoglobulins should undergo the clinical routine examinations in ITP,HSP and KD. Early administration of IVIG might be important to improve disease prognosis and shorten its course of treatment in children with three kinds of immunology related diseases.

Objective:To compare the efficacy and costs of pegylated recombinant human granulocyte colony stimulating factor (PEG-rhG-CSF) and granulocyte colony stimulating factor (G-CSF) for hematopoietic stem cell mobilization and hematopoietic recovery after transplantation in patients with relapsed or refractory malignant lymphoma. Methods:From July 2014 to October 2016, 15 patients with malignant lymphoma using peripheral blood stem cell mobilization (PBSCM) for autologous peripheral stem cell transplantation (APBSCT) were treated in our institution and enrolled in the PEG-rhG-CSF group (experimental group). We analyzed data from other 15 patients with malignant lymphoma mobilized with G-CSF who were treated in our institution from January 2013 to August 2015 (control group). Results:Patients in both groups were successfully mobilized. The median amounts of CD34+cells collected in the experimental and control groups were 16.2×106/kg and 8.9×106/kg, respectively (P=0.414), and the median amount of mononuclear cell (MNC) was 12.4×108/kg and 9.9× 108/kg, respectively (P=0.519). In the experimental and control groups, the mean durations of mobilization were 10.66±1.45 and 9.33±1.83 days (P=0.234), the mean durations of neutropenia during mobilization were 4.20±2.17 and 3.80±2.04 days (P=0.608), the mean durations of absolute neutrophil count recovery after APBSCT were 10.14±1.29 and 10.93±2.69 days (P=0.327), and the mean durations of platelet recovery were 10.36±2.27 and 12.27±3.38 days (P=0.121). Mobilization and hematopoietic recovery after APBSCT were not significantly different between the two groups. The cost was lower in the experimental group than that in the control group (RMB 3,960 yuan versus RMB 11,479.3±2,401.3 yuan). Conclusion:High-dose chemotherapy combined with PEG-rhG-CSF is a promising, effective, and low-cost mobilization regimen for patients with relapsed or refractory malignant lymphoma.

Objective:To investigate the distribution and drug resistance of anaerobic bacteria in the patients with oral and maxillofacial infection.Methods:Aerobic and anaerobic bacteria cultures from 61 specimens of pus from the patients with oral and maxillofacial infection in the Department of Oral and Maxillofacial Surgery,Peking University School of Stomatology were identified.The culture type was evaluated by API 20A kit and drug resistance test was performed by Etest method.The clinical data and antibacterial agents for the treatment of the 61 cases were collected,and the final outcomes were recor-ded.Results:The bacteria cultures were isolated from all the specimens,with aerobic bacteria only in 6 cases (9 .8%),anaerobic bacteria only in 7 cases (1 1 .5%),and both aerobic and anaerobic bacteria in 48 cases (78.7%).There were 55 infected cases (90.2%)with anaerobic bacteria,and 81 anaero-bic bacteria stains were isolated.The highest bacteria isolation rate of Gram positive anaerobic bacteria could be found in Peptostreptococcus,Bifidobacterium and Pemphigus propionibacterium.No cefoxitin, amoxicillin/carat acid resistant strain was detected in the above three Gram positive anaerobic bacteria. The highest bacteria isolation rate of Gram negative anaerobic bacteria could be detected in Porphy-romonas and Prevotella.No metronidazole,cefoxitin,amoxicillin/carat acid resistant strain was found in the two Gram negative anaerobic bacteria.In the study,48 patients with oral and maxillofacial infection were treated according to the results of drug resistance testing,and the clinical cure rate was 81 .3%. Conclusion:Mixed aerobic and anaerobic bacteria cultures are very common in most oral and maxillofa-cial infection patients.Anaerobic bacteria culture and drug resistance testing play an important role in clinical treatment.

Objective To investigate clinical characteristics of relapsing polychondritis(RP)and to improve early recognition for it.Methods Clinical and laboratory data of 56 patients with RP were analyzed retrospectively.Results Ratio of number of male patients to female ones was 1.2.Age at onset was(46?11)years(ranging from 27 to 71)and average interval between onset and diagnosis was(21? 35)months,(8?6),(16?31)and(29?37)months for patients initial onset with auricle,respiratory tract and joints involved,respectively.Site involved included airway in 40 patients(71.4%),auricle in 32 (57.1%),joints in 32(57.1%),eyes in 27(48.2%),nasal chondritis in 25(44.6%)and inner ear in 13(23.2%).At initial stage of the course,17 patients were misdiagnosed as respiratory infection (30.4%),nine as perichondritis(16.1%),six as pulmonary tuberculosis(10.7%),five as rheumatoid arthritis(8.9%).Seven of 40 patients with airway involvement received metallic stents for their tracheobronchial stenosis.Four patients whose condition never improved after regular therapy all had respiratory involvement.Conclusions Patients of RP with initial onset at non-auricle,non-nasal sites tended to be misdiagnosed.Prevalence of airway involvement was not so low with a poor prognosis in patients of RP.

BackgroundDiabetic retinopathy (DR) is the result of the cytokine network disorders,the imbalance of angiogenic factor and vascular inhibitory factor is the start factor.ObjectiveTo analyze the levels of CXC chemotatic factors of type 2 diabetes mellitus patients,evaluate the clinical application value of them in different clinical types of DR using receiver operating characteristic (ROC)analysis and to approach the new way of individualized treatment.Methods This was a prospective research.The gold standard was ophthalmolscope and fundus fluorescein angiography.The levels of CXC chemotatic factors and multiplicaiton factors were measured in 96 cases with type 2 diabetes mellitus (66 cases with retinopathy and 30 cases without retinopathy as control).The assessment tasks were performed for these index and courses of DR with ROC curve.Results The expression of age,course of disease has significant difference in different courses of DR ( F =8.507,P =0.001 ; F =28.143,P =0.000).Compared with the control group,the expression of growth-related oncogene-α ( GROα ) ( t =- 2.172,P =0.035,AUC =0.625 ),whole blood viscosity 200 ( t =- 3.724,P =0.001,AUC =0.904 ) and neutrophilic leukocyte (t=-2.562,P =0.013,AUC =0.577 ) has significant difference in the group of mild NPDR.Compared with the control group,the expression of interferon-γ-inducible protein 10 ( IP-10 ) ( t =-3.591,P =0.001,AUC =0.592 ),platelet derivation growth factor-BB ( PDGF-BB ) ( t =- 3.233,P =0.003,AUC =0.735 ),vascular endothelial growth factor(VEGF) ( t =- 3.617,P =0.001,AUC =0.776 ),C peptide ( t =- 3.366,P =0.002,AUC =0.962 ),leukocyte ( t=-3.201,P =0.003,AUC =0.852) and neutrophilic leukocyte(t =-4.201,P=0.000,AUC =0.852) has significant difference in the group of moderate and severe NPDR.ConclusionsCXC chemotatic factors may act as reactivator in the pathogenesis of DR,GROα and IP-10 may be useful for clinical monitoring of the severity of DR,and evaluating the imbalance state of chemotatic factors maybe a new approach to clinical monitoring and prognosis of DR.
