Objective To establish a method for determination of allicin(diallyl trisulfide) in the ultrafine garlic powder by gas chromatography(GC) . Methods Allicin injection was extracted by supersonic wave with a mixed solvent hexane-anhydrous ethanol(1:4) in GC by capillary column and detected by hydrogen flame ionization detector(FID) ,using nitrogen as the carrier gas. Results The peak areas were proportional to the allicin concentrations and the standard curve showed good linearity,y=190 282.5x-11 734.5(r=0.999 3) within the range of 0.30～3.00 mg/ml,the average recovery was 84.6%-98.6 % with RSD of 1.85%～3.27%. Conclusion The method is simple,accurate with good repeatability,and it is applicable to the determination of allicin in the ultrafine garlic powder.

Objective To observe the TCM syndrome changes of lung cancer patients before and after chemotherapy and the effect of Shengxuetang on dealing with side and toxic effects caused by chemotherapy and patient’s immune function. Method Phase III and IV lung cancer patients were randomly divided into two groups, treatment group and control group. Patients in the treatment group were given the combination of chemotherapy and Shengxuetang, while those in the control group were given the combination of chemotherapy and berbamine. Peripheral WBC count, HGB level, platelet count, T-cell count, and NK cell activity were measured, and other toxic effects were observed before and after chemotherapy. Results Before chemotherapy, there were two syndrome types, one is the deficiency of Qi and Yin, and the other is phlegm-damp due to deficiency of Qi accompanied with blood stasis. During the treatment, these two syndrome gradually transformed to the deficiency of both Qi and Yin and coagulation of phlegm and blood stasis. The chance for patients to develop myelosuppression had no difference between two groups, however, most patients in the treatment group developed grade I myelosuppression, while in the control group, most patients developed grade II myelosuppression. G-CSF was prescribed more in the control group than in the treatment group (P

Objective To evaluate the MRI findings and clinical features of methotrexate-induced acute encephalopathy in children.Methods The clinical data and brain MRI obtained in 13 children with methotrexate-induced acute encephalopathy were retrospectively reviewed.The MRI features were analyzed , including information on the location , the signal intensity and follow-up MRI study was performed.Results Of the 13 patients , 2 patients suffered from seizure.Five patients had dysphasia , of which 4 patients had evidence of hemiparesis , 1 patient had right facial palsy.Five patients had unilateral weakness.And left hemiparesis was observed in 1 patient.DWI revealed well demarcated asymmetrical hyperintensity lesions within the centrum semiovale and/or periventricular white matter in 10 patients, corresponding to areas of hypointensity on ADC maps.One case showed hyperintensity areas in the bilateral supratentorial cortex and subcortical white matter on T 2-weighted images with subtle high-intensity on DWI.In all 10 cases there were resolution of the diffusion abnormality , 8 cases displayed residual FLAIR signal abnormalities involving areas of previously seen diffusion restriction , 5 cases showed decreased range of the lesion , 1 case was progressive, and 2 cases were stable.One case with hyperintensity areas in the supratentorial cortex and subcortical white matter showed small residual hyperintensity on T 2-weighted images and resolution of the diffusion abnormality.Conclusions MTX-induced acute encephalopathy often manifests as stoke-like symptoms.DWI is the imaging modality of choice for the detection of acute MTX neurotoxicity , and asymmetrical restricted diffusion in the deep white matter is the characteristic sign.Cytotoxic edema induced by MTX is transient and reversible .

Objective To observe the influencing factors of recurrence and metastasis for postoperative breast cancer high-risk population, and TCM regimen of syndrome differentiation and treatment was used to validate its significance for the prevention of recurrence and metastasis. Methods The influencing factors of recurrence and metastasis of 178 postoperative breast cancer high-risk cases with positive hormone receptor were studied. The recurrence and metastasis, disease-free survival and accumulative points of TCM symptoms of integrated group (with TCM syndrome differentiation and endocrine therapy) and western medicine group (with endocrine therapy) were compared. Results Lymph node metastasis, cancer staging and TCM therapy had influence on the disease-free survival rate of postoperative breast cancer high-risk patients. TCM therapy was the independent prognostic factor for disease-free survival. 3-year recurrence and metastasis rate was lower in integrated group than that in western medicine group, with statistical difference (P=0.03). The total accumulative points of TCM symptoms in both two groups decreased after treated for 3 and 6 months, integrated group showed greater significance. TCM therapy was better for the treatment of irritability, hot flash and perspiration, good for spontaneous perspiration and insomnia, but poor in dry mouth, bitter taste in mouth and fatigue. Conclusion Lymph node metastasis, cancer staging and TCM therapy are main influencing factors for recurrence and metastasis. TCM therapy with regimen of syndrome differentiation and treatment can reduce 3-year recurrence and metastasis rate, improve TCM symptoms, especially is significant for the improvement of irritability, hot flash and perspiration.

Before and after treatment as well as before metastasis,the combined detection of progastrin-releasing peptide (ProGRP) and neuron-specific enolase (NSE) was performed in 150 patients with small cell lung cancer.The follow-up period was 1 year.Enzyme-linked immunosorbent assay (ELISA) and electrochemiluminescence immunoassay were conducted.The result showed a negative correlation between the serum levels of ProGRP and NSE the curative effect.And a positive correlation existed between the serum levels of ProGRP and NSE and disease development.The difference had statistical significance (P ＜ 0.05).The levels of ProGRP and NSE may be used to indicate the disease development and evaluate the curative effect.

Objective To find an ideal method of DNA isolation from blood and especially from clotted blood and to minimize the volume of blood collected for laboratory and clinical tests.Methods DNAs were isolated from antiagglutinated and agglutinated blood samples from auricular veins of 30 healthy subjects. The DNAs of these samples were obtained by a nonenzymatic, nontoxic procedure optimized by us and determinated by agarose gel electrophoesis and PCR. Results The yields of DNA isolated from clotted blood and antiagglutinated blood were (40.2?8.86)mg DNA/L and (39.1?10.2)mg DNA/L, and purities were 1.87?0.11 and 1.92? 0.12. The DNAs that we isolated from all samples had high molecular weight and by PCR the dimorphism of ALU alleles of the 8th intron of t-PA was easy to be obtained, so they were complete and reliable. Conclusion This method is rapid, easy, efficient and nontoxic for isolation of DNA from clotted and fresh blood and meets requirements for clinical testing and molecular biology study.

Objective To study the correlation of the serum levels of pro-gastrin-releasing peptide (ProGRP) and neuro-specific enolase (NSE) with different treatments in limited-disease small cell lung cancer (L-SCLC) patients.Methods 150 L-SCLC patients were randomly divided into three groups including concurrent chemo-radiotherapy group,sequential chemo-radiotherapy group,and chemotherapy group.The serum levels of ProGRP and NSE were detected by enzyme-linked immunosorbent assay (ELISA) and electrochemiluminescence immunoassay before and after different treatments.The follow-up phase was 12 months.Results The serum levels of ProGRP and NSE were significantly decreased in all 3 groups after treatment (318.96,250.77,226.18 pg/ml and 31.72,23.95,17.89 μg/L),and the lowest level was observed in concurrent chemo-radiotherapy group,then the sequential chemo-radiotherapy group and chemotherapy group.The short term therapeutic effects were in the same sequence,and there was statistical significance between concurrent chemoradiotherapy group and chemotherapy (P ＜ 0.05).The decrease extent of ProGRP and NSE in effective cases (CR+PR) was significantly higher than that in failure cases in all 3 groups.The serum levels of ProGRP and NSE were increased with disease progress (P ＜ 0.05).Conclusion The serum levels of ProGRP and NSE can be used to reflect the patient' s condition and evaluate therapeutic effect in L-SCLC.The concurrent chemo-radiotherapy is more effective than sequential chemo-radiotherapy and chemotherapy only in L-SCLC.
