[Objectivej To establish a gas chromatography (GC) method for the determination of the content of camphor, isoborneol and borneol in Anmo Ointment. [ Methods ] The determination was performed by programmed temperature GC, in which a 100% concentration of dimethylpolysiloxane was used as stationary liquid phase and the GC was equipped with FID detector at 300℃. [Results] The isolation and the linearity were fine with the rate of recovery of camphor 100.5% (RSD being 1.4%), isoborneol 99.1% (RSD being 1.8%) and borneol 100.8% (RSD being 1.3%). [Conclusion] This method is sensitive, rapid and accurate. It can be used to control the quality of Anmo Ointment.

Objective To observe the correlation between CD4+ CD29+ T cells and metastasis and radiotherapy for patients with pulmonary adenocarcinoma. Method Seventy-one patients with lung adenocarcinoma, 93 patients with lung adenocarcinoma ,76 cases of chronic obstructive pulmonary disease (COPD),63 cases of healthy volunteers were enrolled. Frequencies of blood CD4+ CD29+ T cells and their intracellular necrosis factor alpha(TNF-α)and interleukin 1(IL-1)were compared. Compare TNF-α,IL-1,integrin beta 1 and vascular endothelial growth factor(VEGF)levels in the patients with transferred pulmonary adenocarcinoma or with non-transferred pulmonary adenocarcinoma and their changes with the treatment of radiotherapy. Results the patients with lung adenocarcinoma and non lung adenocarcinoma were significantly higher than that of COPD and health group,and patients with lung adenocarcinoma is significantly higher than patients with non lung adenocarcinoma (P<0.05);Integrin beta 1,VEGF and CD4+CD29+T cells,TNF-αand IL-1 level in patients with lung adeno-carcinoma metastasis were significantly higher than non-transferred group(P < 0.05);After radiotherapy,CD4+CD29+T cells,TNF-αand IL-1 in patients with lung adenocarcinoma were significantly lower than before(P<0.05);CD4+ CD29+ T cells,TNF alpha and IL-1 with integrin beta 1 and VEGF had significantly positive correlations. Conclusion CD4+CD29+T cells and cytokines increase significantly in the blood of patients with lung adenocarci-noma,and are related to the prognosis of metastasis and radiation therapy,which has important clinical significance.

Aim To study the preventive and therapeutic effects of Buyang Huanwu Decoction(BYHWD)on denervated tibial muscle atrophy of rats.Methods After 60 Sprague-Dawley rats were subjected to Common Peroneal nerve crush model of 5 mm injury, they were randomly divided into 6 groups for daily intragastric administration of drugs:BYHWD high-dose, medium-dose, low-dose groups, mecobalamin group(positive control), model group, sham operation group.The drug administration lasted for 18 days.18 days after operation, slice, masson staining and analysis morphology were performed. The wet weight ratio and section area of tibial muscle were also measured.Results Tibial muscle section area of sham operation group was large, morphous was regular, while that of model group significantly diminished, structure was chaotic, and connective tissue hyperplasia was more obvious;Tibial muscle section area of BYHWD group and mecobalamin group was fairly diminished, morphous was fairly regular, and connective tissue hyperplasia was not obvious.Compared with model group, the section area of BYHWD group all increased significantly(P <0.01)in a dose-dependent manner.Compared with mecobalamin group, the cross section area of BYHWD high-dose group was significantly larger(P <0.05).Compared with model group, the wet weight ratio of BYHWD high-dose and medium-dose group all increased significantly(P <0.01 or P <0.05)in a dose-dependent manner.Conclusion BYHWD has a significant effect of prevention and therapy on denervated tibial muscle atrophy of rats.

Objective To investigate the histopathologic characteristics of bladder tumor and provide theoretical basis for the reasonable selection of treatment modality.Methods This retrospective study collected the pathological data of 4 200 bladder tumor from May 2001 to October 2014.There were 3 443 male and 757 female, and the average diameter of these tumors was (1.8 ± 0.6) cm (ranged 0.2 to 6.5 cm).Among all cases, 3 214 (76.5%) cases were solitary tumor while 986 (23.5%) were multiple tumors.The histologic subtype, pathological grade and stage, the existence of vascular and lymphovascular invasion, tumor in situ, abnormal variants and rare subtypes were recorded and analyzed.Results 162 cases (3.9%)were benign tumors and 4 038 cases (96.1%)were malignant tumors including 4 008 cases of urothelial cancer (UC), 18 cases of primary adenocarcinoma and 12 cases of primary bladder squamous carcinoma.Furthermore, 2 460 (61.4%)cases were high grade UC while 1 548(38.6%)cases were low grade.320 cases were found intravascular tumor embolus or lymphovascular tumor thrombus and 391 (9.3%)cases were found metaplasia of squamous epithelium.Moreover, there were 230 cases of squamous differentiation, 120 cases of glandular differentiation, 110 cases of both squamous and glandular differentiation, and 39 cases (0.9%)of other rare subtypes or variations.On pathological stage, 112 (2.8 %) cases were carcinoma in situ, 548 (13.7%)cases were Ta, 2 599(65.1%)cases were T1, 480(12%)cases were T2, 92 cases(2.3%)were T3 and 23 cases(0.6%)were T4 stage, with the rest cases being unable to be accurate staging.Multiple Logistic regression analysis revealed that lymphovascular invasion was related to tumor grade , pathological stage and abnormal differentiation (P < 0.02).Moreover, UC with squamous and glandular differentiation were related with tumor recurrence and progression (P =0.02).Conclusions Most bladder tumors were high grade and low stage urothelial cancer with various forms of differentiation.Squamous and glandular differentiation were most common variation which should be avoided to diagnosed as hybrid carcinoma.Lymphovascular tumor thrombus and abnormal differentiation were correlated with tumor stage and grade.

We used adsorption method to immobilize the lipase by using nano-silica dioxide as the carrier. And we also studied different immobilization conditions effects on the catalytic activity. We got optimize immobilization conditions which were as follow the lipase quantity of 28,300 U/g, temperature of 45 degrees C, pH of 7.5 and treated for 10 h. Under these conditions the immobilized lipase activity yield 3867 U/g carrier. The best reactive temperature for immobilized lipase was 45 degrees C and higher than 5 degrees C for free enzyme, and the optimal pH dropped to 5.5 compared that of free enzyme (pH 7.0). The immobilized lipase stability for thermal and pH are improved than free lipase. When temperature was below 70 degrees C the immobilized enzyme activity was over 70% than initial activity. The free lipase activity just kept original 30% at 50 degrees C. When pH was 5-8, the immobilized lipase activity was still more than 50% and the free lipase only remained 20%. When we used the immobilized neutrophil lipase catalyzing different oil to produce biodiesel such as soybean oil, rapeseed oil and waste oil, the esterification rate of rapeseed oil was the highest.

Recently, accumulating evidence suggests that high bilirubin level is involved in the pathophysiology of schizophrenia. High bilirubin level during early childhood may increase the risk of being suffered from schizophrenia after adulthood, and schizophrenia patients with high bilirubin level have aggravated psychiatric symptoms. As compared with other psychiatric patients and general population, schizophrenia patients usually have relatively higher bilirubin level; high bilirubin level is associated with acute psychotic states, positive symptoms, and poor prognosis in patients with schizophrenia. This article reviews the relation between bilirubin and schizophrenia and its potential pathophysiological mechanism in order to provide a new direction for the study of schizophrenia pathogenesis and auxiliary diagnosis.
