Objective To investigate characteristics of TCM syndromes of pulmonary tuberculosis,and to explore new methods for its treatment. Methods TCM syndrome scale was designed to investigate and summarize the characteristic of the syndrome, the syndrome of the general information, and the main clinical symptoms of 516 pulmonary tuberculosis patients. Results The between-group comparison of distribution of TCM syndromes in patients with pulmonary tuberculosis showed statistical difference (P＜0.05) . The occurrence rate of TCM syndromes in the 516 pulmonary tuberculosis patients were listed in descending order as follows:syndrome of both Qi and yin deficiency complicated with stasis ＞ syndrome of lung yin deficiency complicated with stasis＞syndrome of both Qi and yin deficiency＞syndrome of yin deficiency with various with age (P＜0.05) . Patients with blood stasis syndrome occupied 66.15% of the total number in the youth group; Patients with blood stasis syndrome occupied 78.03% of the total number in the middle-aged group;distribution of TCM syndromes was statistically different with the initial treatment and re-treatment (P＜0.05) .Patients with the blood stasis syndrome occupied 72.73% of the total number in the initial group, patients with effulgent fire ＞ lung yin deficiency syndrome.① The distribution of TCM syndromes was statistically various with age (P＜0.05) . Patients with blood stasis syndrome occupied 66.15％ of the total number in the youth group; Patients with blood stasis syndrome occupied 78.03％ of the total number in the middle-aged group; Patients with blood stasis syndrome occupied 78.22％ of the total number in the old-aged group. ② The distribution of TCM syndromes was statistically different with the initial treatment and re-treatment (P＜0.05) . Patients with the blood stasis syndrome occupied 72.73％ of the total number in the initial group, patients with the blood stasis syndrome occupied 75.61％ of the total number in the re-treatment group.③ The distribution of TCM syndromes was statistically different with the main symptoms (P＜ 0.05 ) . Conclusion All 516 cases of pulmonary tuberculosis had Yin deficiency. There were 380 patients had the stasis, occupying 73.64%.Therefore, the methods of nourishing yin and removing blood stasis should be used to treat patients with pulmonary tuberculosis.

The supramolecular inclusion properties of beta-cyclodextrin (beta-CD) and resveratrol (Res) were investigated using drug-protein interaction spectroscopy method. The differences between the results of interaction spectroscopy method and the results of classical method were compared. The total energy of the stable inclusion of cyclodextrin-resveratrol was calculated by Gaussian theory calculation. The stable inclusions in the process of interaction between resveratrol/inclusion complex and bovine lactgoferrin (BLF) were studied by molecular modeling. The results showed that the interaction spectroscopy method could explain the property of the inclusion in a more sensitive manner, it also interpreted the conveying mechanism of BLF binding with inclusion complex. The molecular modeling result showed consistent results with Gaussian theory calculation; both of the two methods obtained the stable configuration of beta-CD-Res inclusion. The relevant result provided an experimental consequence for the pharmacology research of beta-cyclodextrin-resveratrol inclusion complex as well as offering a new reference to the future research of supramolecular inclusion compound.

This study was aimed to search anti-platelet aggregation effectors from Gardenia jasminoides extract with the employment of platelet affinity extraction method coupled with HPLC, in order to provide pharmacological experi-mental evidences of the selected effectors to verify its feasibility. Under physiological conditions, washed rat platelets were added into G. jasminoides extract and then a mixture was gained. Consequently, some components from G. jas-minoides extract were combined to the platelets in the mixture while some were not owing to their special chemical structures and properties. Firstly, the uncombined components were washed off from the mixture. Secondly, the com-bined components in the leftover was washed down and collected, respectively, right after destroying the occupied platelets' structures. Thirdly, different collected eluents were analyzed, respectively, by HPLC established in the pre-vious work to search the effectors. Fourthly, pharmacological experiments were implemented for confirmation. The re-sults showed that dominant effective components from G. jasminoides extract acting on anti-platelet aggregation were identified as geniposide. Further evident was provided as well by pharmacological experiment that geniposide exhibit-ed significant inhibitory effect on anti-platelet aggregation in rats induced by ADP, rat tail collagen and thrombin(P< 0.01). It was concluded that the platelet affinity extraction-HPLC method proposed in this paper can be utilized to analyze the correlation of effectors from G. jasminoides extract and its pharmacological effects. Moreover, there are some correlations between screened chemical substances and their pharmacological effects.

OBJECTIVETo study the clinicopathologic features of tuberous sclerosis complex (TSC).

METHODSThe clinicopathologic data of the patients diagnosed as TSC with refractory epilepsy and resection of epileptic focus were retrospectively analyzed.

RESULTSFourteen cases were included, the mean age was (15.8±12.9) years, with a male predominance (male to female ratio=10:4). Frontal lobe was the most common (13/14) site of involvement. MRI showed multiple patchy long T1 and long T2 signals. CT images showed multiple subependymal high density calcified nodules in nine cases. Histology showed mild to severe disruption of the cortical lamination, cortical and subcortical tubers with giant cells and/or dysmorphic neurons. The giant cells showed strong immunoreactivity for vimentin and nestin, while the dysmorphic neurons partially expressed MAP2 and NF. Vimentin also stained strongly the "reactive" astrocytes. Thirteen cases had follow-up information: Engel class I in six cases, Engel class II in six cases, and Engel class III in one case.

CONCLUSIONSDiagnosis of TSC relies on combined pathologic, clinical and neuroradiological features. Immunohistochemical staining can be helpful. Resection of epileptic focus is an effective method to treat refractory epilepsy in TSC.

Objective To investigate the serum levels of dickkopf-related protein 1 (DKK1) and sclerostin (SOST) in patients with axial spondyloarthritis treated with selective cyclo-oxygenase 2 inhibitor and its relation to clinical efficacy.Methods A randomized double-blind controlled trial with axial spondyloarthritis (ax-SpA) was carried out in our hospital.The data from patients in a single center was collected and analyzed.Serum DKK1 and SOST levels were measured by enzyme-linked immuno sorbent assay (ELISA)method before and after 12 weeks treatment,then correlation analysis were conducted for DKK1 and SOST levels with erythrocyte sedimentation rate (ESR),C reactive protein (CRP),Bath ankylosing spondylitis disease activity index (BASDAI),Bath ankylosing spondylitis functional index (BASFI) and SPARCC of the sacroiliac joint inflammation score.Chi-square tests were used for analyzing of categorical data.Fisher exact tests were performed when the expected frequencies were less than 5.Two independent samples t-test was used to compare the difference between groups.Single sample t-test was used to ompare the differences between data before and after treatment.Pearson or Spearman correlation was used for correlation analysis.Results After 12 weeks of treatment,a total of 116 patients completed the follow-up,including 57 cases of imrecoxib group and 59 cases of the celecoxib group.There were no statistically significant difference between the two groups (P＞0.05).The level of serum DKK1 was significantly increased after treatment [(393±137) pg/ml,vs (542±274)pg/ml,P＜0.05].The serum level of SOST increased significantly [(39±19) pg/ml vs (57±36) pg/ml,t=5.814,P＞0.05],too.The difference between the two groups was not statistically significant (P＞0.05).Spearman correlation analysis showed that serum DKK1 was positively correlated with serum SOST (r=0.226,P=0.015).A significantcorrelation was found between SOST level and ESR,CRP,finger to floor distance,left and fight lumbar side flexion and Schober's test (ESR:r=-0.379,P＜0.01;r=-0.309,P=0.001;r=-0.225,P=0.015;r=0.185,P=0.047;r=0.247,P=0.008;r=0.214,P=0.021).Conclusion Imrecoxib and celecoxib have similar efficacy on relieving the signs and symptoms of patients with ax-SpA.Short-term application of selective COX-2 inhibitors can increase DKK1 and SOST and possibly delay radiographic progression.
