Objective:To optimize the extraction process of Hegan Lidan granules. Methods:In order to choose the optimal tech-nological parameters, the content of baicalin was determined by HPLC. An orthogonal method was utilized with solvent volume, extrac-tion time and extraction times as the impacting factors and the content of baicalin and extraction rate as the indices. Results:The opti-mal parameters were as follows:using 8-fold water as the solvent, the raw material was extracted three times with 2 h for each. Con-clusion:The process is steady and feasible, and can be used in the extraction of Hegan Lidan granules.

Objective: To establish the quality standard for compound Heishen pills. Methods: Scrophulariae Radix, Radix et Rhizoma and Belamcancae Rhizoma were identified by TLC. HPLC was used to determine the content of harpagoside and cinnamic acid in Scrophulariae Radix on a Welchrom-C18 column using methanol-acetonitrile-1% ethylic acid (8∶21∶71) as the mobile phase. The flow rate was 1. 0 ml·min-1 . The column temperature was at 30℃ and the detection wavelength was set at 278 nm. Results:The TLC method had good specificity without interference from negative control. The linear range of harpagoside was 1. 32-65. 80μg·ml-1 with the average recovery of 98. 06%(RSD=2. 16%),and that of cinnamic acid was 0. 38-19. 20 μg·ml-1 with the average recovery of 98. 78%(RSD=1. 34%). RSDs of precision, stability and reproductibility tests were all below 2%. Conclusion: The established method is accurate, feasible and reproducible. It can be used in the quality control of compound Heishen pills.

Objective Acute necrotizing pancreatitis (ANP) may cause lung injury.This study explores two factors that are associated with lung damage from ANP,the expression of tumor suppressor factor CYLD and nuclear factor-kappa B (NF-κB).Methods 72 adult Sprague-Dawley rats were randomly divided into 3 groups:sham operation,ANP,and GdCl3 treatment groups (n=24 for each group).A retrograde injection of 5％ sodium taurocholate into the biliopancreeatic duct of rats induced ANP,and the animals were killed 1,3,6,and 12 hours after the ANP induction.AMs were harvested by bronchoalveolar lavage technique,and TNF-a and IL-1β levels in bronchoalveolar lavage fluid (BALF) were evaluated.Lung tissue was checked with histological examinations,and the activity of NF-κB and CYLD in AM were measured by western blot.Results TNF-α and IL-1β secreted by AM were gradually elevated,peaked on the sixth hour,had maximums of (491.3 ±20.3)ng/L and (178.83±11.32)ng/L respectively,and decreased on the twelfth hour.The levels of TNF-α and IL-1β in the ANP group were significantly higher than the sham operation group (P＜0.05),and the GdC13 group levels were obviously lower than ANP group.In the sham operation group,the expression of NF-κB was low and CYLD was high.In the ANP group,when compared to the sham operation group,the expression of NF-κB rose after 3 hours and continued to rise with time progression (P＜0.05).In contrast,CYLD protein expression in the ANP group dropped after 3 hours and continued to gradually decrease (P＜0.05).The CYLD and NF-κB protein expression in GdCl3 groups had similar trends as the ANP group.GdCl3 group CYLD levels began to rise at 6 hours (P＜0.05),and NF κB levels began to fall at 1 hour (P＜0.05).The expression of NF-κB and CYLD possessed a negative correlation in both the ANP and GdCl3 groups (r =-0.918,r=-0.723,P＜ 0.01).Conclusions Therefore,in acute lung injury associated with acute pancreatitis,CYLD expression decreased with evident phases,such as a decrease in levels after 3 hours,and NF κB expression increased.Also,GdCl3 may be responsible for upregulation of CYLD expression and downregulation of NF-κB expression,and confirmed that CYLD had a negative effect on NF-κB.Perhaps GdCl3 could be used in the future to ameliorate the lung injury associated with ANP.

Objective To explore the relationship of acute myeloid leukemia kayotype with chemotherapeutic effect. Methods Conventional cytogenetic technique of G-band was used to analyze in 222 acute myeloid leukemia patients. Results Eighty-six cases (42. 1%) with cytogenetic abnormalities were found in 204 patients. Excepting for M_3 patients,the favorable,intermediate and adverse groups according for MRC criteria were treated with TA or CAG schema respectively. CR rate of M_3 was obviously higher than non-M_3. The favorable and intermediate group were obviously surpassinger than adverse group in TA schema. CR rate of the intermediate group was highter than that of other groups in CAG schema. CR rate of the adverse group in two schema were all low. CAG was surpassinger than TA schema in intermediate group. Conclusion Cytogenetics is an important chemotherapeutic and prognostic factor to acute myeloid leukemia. CAG schema could be the leader selection in the de novo presby or oligoac-crementional AML patients.

Objective To understand acute rejection differences between untreated recipients and rapmycin-treated recipients in a rat free flap allotransplantation model. Methods Brown groin free flaps were transplanted to Lewis recipients. In the treated group, recipients were treated with rapamycin at the dose of 4 mg/kg every day from day 0 to day 14 after transplantation. In the untreated group, recipients didn't receive any treatment. Allografts were evaluated clinically and histologically. Results Allografts in the treated group showed epidermolysis as sign of rejection.Rejection sign of untreated grafts was ischemic necrosis of whole skin. In histological evaluation, the treated grafts showed "band-like" lymphocytes infiltration in the upper dermis when rejection occurred, while the untreated grafts showed thrombosis in the subdermal vessels. Conclusion The differences between the two groups implied that embolization may be responsible for the rejection of free flap allotransplantation in rat model.
