Chinese Journal of Information on Traditional Chinese Medicine 2013;(11):16-18,19
Objective To explore the key elements in prescription and summarize the law of prescription-herb treatment, to find core herbs/herb group which play a key role in pharmacological effects, then provide new methods and modern techniques for theory of prescription development and TCM clinical research. Methods The text data sources of stroke disease were retrieved from databases of traditonal Chinese prescription. After pre-processing and information extraction, a prescription-herb matrix was constructed, and then biclustering method was used to simultaneous clustering two dimensions of data. Results Totally 648 effective records were gained after preprocessing, and 6913 herbs were extracted, then a 100×648 prescription-herb matrix was generated. Finally 4-way clustering results were output, along with 8 high descriptive prescriptions, then characteristics of prescription laws of diagnosis and treatment according different syndrome and various types of herbs commonly used were summarized. Conclusion This method can be well applied for prescription-herb knowledge discovery in TCM prescription databases. The prescription-herb information can be effectively extracted, and laws of prescription-herb and syndrome-treament can be mined.

China Journal of Traditional Chinese Medicine and Pharmacy 2005;0(06):-
Objective:By observing effects of Dahuang Zhechong Pills on CD44,VEGF and the metastasis suppressor in mice with Lewis Lung carcinoma,to discuss its mechanism of anti-tumor metastasis preliminarily.Methods:The mice were divided randomly into five groups the day after modeling and each group included ten mice.According to the pre-test,high-dose,medium-dose and low-dose were quantitated with 0.18g/ml,0.09 g/ml,0.045g/ml.The model group was intragastric administrated with NS 0.2ml for ten days;the chemotherapy group was Intraperitoneal administrated 50mg/kg CTX on the first day.Observing and numerating the pulmonary metastases with nodules by pulmonary pressure slide film on the 12th day.Based on immunohistochemical method to detect the expression of VEGF and the activity detection by flow cytometry CD44,Its anti-tumor mechanism and the role of target were preliminarily studied.Results:The inhibition rates of lung spontaneous metastasis in experimental groups of high(H),medium(M),low(L)dosages and the chemotherapy group were respectively 57.44 percent, 55.32 percent,38.72 percent,60.00 percent.CD44,respectively,values were 0.59?0.86,0.21?0.28,0.33?0.31,1.36?0.52; the experimental group(M)compared with model group,VEGF expression was significantly reduced,there was a significant difference(P0.05).Conclusion:Dahuang Zhechong Pills reduced the lung metastases incidence of C57BL mice with Lewis lung carcinoma and prolonged their lives.These results were obvious in the medium-dose experimental group.Medium-dose of Dahuang Zhechong Pills had effects on C57BL mice with Lewis lung carcinoma,whose CD44 activity were inhibited and the expression of VEGF was reduced.

Eight-weeks old C57BL/6J male mice were treated with normal or high fat diet for4 weeks,and then bone mass,number and activity of osteoclasts,differentiation of osteoblasts from bone marrow mesenchymal cells and the change in lipid genes expression were studied.Compared with the normal diet treated group,bone mass of femur from high fat diet treated animal was decreased,but there were increased number and activity of osteoclasts and raised lipid genes expression levels.Besides,no obvious change was found in differentiation of osteoblasts from bone marrow mesenchymal cells.The loss of bone mass induced with high fat diet in young mice was mainly due to increased activity of osteoclasts and bone resorption.

Objective To investigate the expression of MIF in PBMC, sera and lacrimal fluid samples in patients with AD, and study the diagnostic significance of MIF in AD. Methods Forty-three AD patients (11 mild AD patients,23 moderate AD patients, 9 severe AD patients classfied by SCORAD index)and 31 age- and sex-matched healthy control subjects were recruited. Real-time RT-PCR was employed to analyze the expression of MIF mRNA in PBMC. ELISA was performed to detect the concentrations of MIF in sera and lacrimal fluid samples. Results AD patients had significantly higher levels of MIF mRNA in PBMC than normal controls [7.46 (3.38-8.90) vs 1.67 ( 1.24-2.45 ), Z=-6.141, P < 0.05]. The concentrations of MIF in sera and lacrimal fluid samples in AD patients were also markedly higher than those of normal controls [serum 36. 32( 11.89-43.80) μg/L vs 7.89(6.13-9.54) μg/L, Z = -6.180,P <0.05; lacrimal fluid 12.66(2.01-20.12) μg/L vs 0.85(0.77-1.06) μg/L, Z = -4.118,P <0.05]. MIF mRNA levels were 2.35 ( 2.12-2.49 ) , 7.83 ( 6. 54-8.90 ) and 8.76 ( 8.22-9.73 ) in mild, moderate and severe AD respectively, and the expression was higher in moderate and severe AD than in normal controls (Z= -6.237, -4.520,P <0.05). MIF serum concentrations were 8.98(7.90-10.51) μg/L, 36.50 (29.78-43.23) μg/L and 45.70(41.27-48. 84) μg/L in mild, moderate and severe AD respectively, and the differences were significant in moderate and severe AD compared to normal controls ( Z = - 6.238,- 4.521, P < 0.05 ). The lacrimal fluid MIF oncentrations were 1.10 ( 0.83-1.35 ) μg/L, 12.66 ( 9.76-15.87) μg/L and 24. 65 ( 19.29-30.94) μg/L in mild, moderate and severe AD respectively. Similarly,they increased significantly in moderate and severe AD compared to normal controls (Z = -4.062,- 3.372, P < 0.05 ). In moderate and severe AD, MIF mRNA levels in PBMCs and MIF concentrations in sera and lacrimal fluid samples were all positively correlated with the severity of AD ( r = 0.395, 0.404,0.515, P < 0.05 ). Conclusions The expression of MIF in PBMCs, sera and lacrimal fluid samples is higher in different course of AD. MIF can serve as a useful laboratory parameter for evaluation of AD activity and severity.

Objective To investigate postoperative complications and proper treatment of craniopharyngioma after microsurgical resection. Methods The postoperative complications and treatments of 58 patients with craniopharyngioma who underwent microneurosurgical resection in our department were analyzed retrospectively. Results In the 58 cases ,45 cases received total resection, 11 cases received subtotal resection, and 2 cases received partial resection. Different levels of postoperative complications occurred in all of the cases, with diabetes insipidus in 55 cases , hypematremia and hyperchloraemia in 32 cases, hyponatremia in 25 cases, hyperpyrexia in 24 cases and hyperglycosemia acidosis in 2 cases. Forty-seven cases recovered clinically,9 cases improved,and 2 cases died. Conclusions Postoperative intensive monitor of water intake,and discharge,fluctuation of electrolyte, and actively correction of diabetes insipidus and electrolyte disturbances and maintaince of fluid balance may play an important role in postoperation treatment of craniopharyngiomas.

Objective To investigate prevention and treatment of parastomal hernia. Methods Clinical data of parastomal hernia of 44 cases were analyzed respectively with special respect to clinical features and repair methods. Result Simple sutures were used in 23 cases, mesh repair in 16 cases, stoma relocation plus mesh repair in 5 cases. Postoperative recovery was satisfactory in 39 cases. Incisional infection occurred in 5 cases, and hernia recurrence developed in 3 cases (6.8%) during a follow-up of 6 to 108 months (average 49 months) in 41 patients. Conclusion The causes of parastomal hernia are miscellaneous especially incisional infection; Perioperative malnutrition must be corrected companying diseases properly controlled, and operative technique improved to prevent the incidence of parastomal hernia; Surgery is the only cure for parastomal hernia. Mesh repair and/or stoma relocation is sometimes necessary.

In this case-control study, the effect of insulin sensitivity on the genesis of cholesterol gallstones was not affirmed. However, raised 2h insulin level during glucose tolerance test and systolic blood pressure were risk factors in gallstone formation. Besides, less physical activity, lower serum total cholesterol and lower HDL-C concentration were found in patients with cholesterol gallstone.
