Objective To study expression of p27 and cyclin D 1 proteins and their significance in non-Hodgkin's lymphoma (NHL).Methods The expression of p27 and cyclin D 1 proteins were detected by imunohistochemical technique in 77 cases of NHL.Results Of 77 NHLs, the positive rates of p27 and cyclin D 1 protein were 51 9% (40/77) and 58 4% (45/77) respectively, and the positive intensity of p27 in low grade group was significantly higher than in high grade group (P

Eight-year program education is the heated topic in the field of medical education across the country.The system of eight-year program education can be discussed as a system,from the view of system philosophy.We analyzed beth internal relationships and external relationships connected to the system,so as to look upon the eight-year program education in its entirety.And then we discussed about the problems of epistemology and methodology on that basis.

Aim To investigate the interactions be-tween the neuroinflammation caused by lipopolysaccha-ride(LPS) and brain CYP2E1.Methods The human cholinergic neuroblastoma cell line IMR-32 was treated with LPS ( 0.1 mg · L-1 , 1.0 mg · L-1 ) , and the LDH and SOD activities were determined after 24 h in-cubation .In order to determine the roles of MAPK sig-naling pathway in the regulation of CYP 2E1 by LPS, the IMR-32 cells were treated with p38 pathway inhibi-tor SB203580 or ERK pathway inhibitor U 0126 for 45 min before the incubation with LPS .The human do-paminergic neuroblastoma cell line SH-SY5Y with CYP2 E1 over-expression was established . The LDH and SOD activities were determined in SH-SY5 Y cells over-expressed CYP2 E1 and control cells treated with LPS(0.1 mg· L-1 , 1.0 mg· L-1 ) for 24 h.Results
The levels of LDH in IMR-32 cells treated with high-dose LPS were increased by 1.38-fold ( P <0.01 ) compared with the control group , and the levels of SOD reduced by 15.0%( P <0.01 ) .Compared with the control, CYP2E1 mRNA and protein levels in IMR-32 cells treated with high-dose LPS were increased by 1.25-fold(P<0.01) and 1.19-fold(P<0.05).The up-regulation of CYP2E1 by LPS could be attenuated by SB203580 and U0126 pretreatment.Compared with the control cells, the CYP2E1 over-expression in-creased LDH levels by 1.28-fold ( P<0.01 ) and de-creased SOD levels by 3.53-fold ( P<0.01 ) after the low-dose of LPS treatment .The CYP2E1 over-expres-sion increased LDH levels by 1.54-fold ( P <0.01 ) and decreased SOD levels by 2.17-fold( P<0.01) af-ter the high-dose of LPS treatment , compared with the control cells.Conclusions LPS can induce CYP2E1 mRNA and protein levels , and the p38 and ERK sig-naling pathway may be involved in the regulation .The elevated CYP2 E1 levels aggravate the damage to neuro-nal cells caused by LPS .Brain CYP2E1 may be an im-portant contributing factor to the pathological process of neuroinflammatory injury .

Objective: To improve the quality control level of ethanol extraction process of Corydalis Rhizoma (CR) by using quality by design (QbD), so as to meet the extraction requirements of Kedaling Tablets. Methods: The critical process parameters were solvent multiple, extraction time and soaking time, and the critical quality attributes were dry extract rate, content and transfer rate of dehydrocorydaline. The response surface methodology was used to establish the mathematical model between the critical process parameters and the critical quality attributes. The overlapping design space of multiple index design spaces was established to select the optimal operation space, where the process verification was carried out. Results: The operating space parameters of ethanol extraction of CR was 14-24 h of the immersion time, 3.0-4.0 times of the first time solvent multiple, 1.5-2.0 times of the second and third time solvent multiple, and 1.5-2.5 h of the extraction time. Under this operating space, the extraction yield of CR was ranged from 6%-8%, the content of dehydrocorydaline was more than 2.8%, and the transfer rate was not less than 85%. Conclusion: The concept of QbD is helpful to improve the ethanol extraction process of CR, and to obtain a reliable and suitable extraction operation space for the production of Kedaling Tablets.

OBJECTIVE: To establish the preparation technology of Moutan Cortex standard decoction and formula granules. METHODS: Moutan Cortex standard decoction was prepared by decocting pot and the parameters and fingerprints of 15 batches of decoction were established.To improve the preparation process of Moutan Cortex formula granules, paeonol was quickly recovered by using volatile oil collection device in the process of vacuum concentration, and the collected paeonol was added back to the concent rated solution.Then, the formula granules of Moutan Cortex were prepared by spray drying and dry granulating.The correlation between the decoction pieces, extract, concentrate, powder, formula granules and standard decoction were compared by taking the contents of paeoniflorin, paeonol and fingerprint as indexes. RESULTS: The range of parameters for Moutan Cortex standard decoction(70%-130% of the average value) were as follows:the dry extract rate was 19.46%-36.14%. The content of paeoniflorin was in the range of 1.83%-3.40%, and the transfer rate was 60.32%-100.00%. The content of paeonol was 1.25%-2.33%, and the transfer rate was 14.42%-26.78%.The contents of paeoniflorin and paeonol in the formula granules of Moutan Cortex conformed to the range of standard decoction parameters. CONCLUSION: The parameters of Moutan Cortex standard decoctions prepared by decocting pot are confirmed, and a new preparation process of Moutan Cortex formula granules is established.Both of standard decoction and formula granules have good consistency in the contents of the index components,which could provide a certain scientific basis for the guidance of actual production.

Peroxisome proliferator-activated receptors (PPARs) are nuclear transcriptional factors closely related to glucose and lipid metabolism, insulin sensitivity. Activation of PPARs targets treated type 2 diabetes, obesity, hypertension and other metabolic diseases by insulin resistance. Recently, a variety of active ingredients of traditional Chinese medicines (TCMs) have been proved to activate PPARs targets for improving insulin resistance, which has attracted widespread attention at home and abroad. In this paper, we reviewed the pathological mechanisms between insulin resistance and PPARs, and summarized the active ingredients of TCMs improved insulin resistance based on PPARs targets. This paper may provide some theoretical guidance for the development of new drugs and TCMs.

Objective To analyze the effect of dominant accessory atrioventricular pathways (AP) on the end vector of ventricular depolarization. Methods All patients had single AP confirmed by radiofrequency cathteter abalation (RFCA) and were free from organic heart disease (including 102 cases of dominant accessory AP and 38 cases of concealed AP). The AP was divided into posterior septal(P3) ,mediate septal (MS) ,anterior septal (AS), left posterior free wall (LP), left anterior free wall (LA), right posterior free wall (RP) and right anterior free wall (RA). Results The end 40 ms vector of QRS wave changed in 102 patients with manifested AP and in 4 patients with concealed AP (P < 0. 05). Conclusion The end 40 ms vector of QRS wave of any site manifested AP can change and the changes have the specihty of leads.

OBJECTIVETo understand the real world, the use of ultra- treatment Shuxuetong injection on liver and kidney functions are affected.

METHODThe 18 hospitals of the country's HIS data sources from which to choose to use Shuxuetong injection, between the ages of 18 to 80 years, using Shuxuetong and the first seven days after discontinuation of at least 7 days has once aspartate aminotransferase or alanine aminotransferase, or creatinine or blood urea nitrogen were measured value as a research object, the number of days of medication is based on more than 14 days, divided into treatment group and the normal course of super-group to reach the normal range of physical and chemical indicators 200% of the upper limit is defined as abnormal. Using the propensity score method, balance the known confounding factors, differences in the occurrence of abnormal renal function and compared between the two groups.

RESULTThe treatment group and the normal course of super-group, resulting in alanine aminotransferase, aspartate aminotransferase, creatinine, urea nitrogen equally likely targets abnormal changes, no statistically significant difference.

CONCLUSIONBased on the available data did not find "super treatment using Shuxuetong damage the liver and kidney function" the situation, but the clinical disease lasts insist on the principle can not be arbitrarily extended treatment to prevent long-term medication.
