This study was aimed to observe four kinds of kidney-tonification medicine, which were Epimedium, pso-ralen, Ligustrum lucidum, Polygonum with the active ingredient of icariin, psoralen, oleanolic acid, stilbene glucoside and their orthogonal compatibility. There were two kinds of non-kidney tonification medicine, which were Chuanx-iong and astragalus with the active ingredient of TMP and astragaloside. The observation was made on the regulatory role of rat bone marrow stem cells (BMSCs). A total of 65 SD rats were randomly divided into the normal control group, positive transformed control group, kidney-tonification compatibility group (including Group 1, Group 2, Group 3, Group 4, Group 5, Group 6, Group 7, Group 8, and Group 9), non-kidney tonification medicine control group (in-cluding TMP group and astragaloside group). Intragastric administration of medication was given to the kidney-tonifi-cation compatibility group and the non-kidney tonification medicine control group, once a day for 3 consecutive days. Intragastric administration of equal amount of normal saline was given to the normal control group and the posi-tive transformed control group. On the third day of intragastric administration, rats in each group were sacrificed. Serum containing medication was used in the culture of BMSCs for 6, 12, or 18 days. ELISA method was used to quantitatively detect the expression activity and content of BMP2 on the 6th, 12th, or 18th day, in order to evaluate the degree of bone cell differentiation degree. Real-time quantitative PCR method was used for detection of expression of Bmp2, Smad1, Smad4 mRNA in serum containing medication in the culture of BMSCs on the 18th day. The results showed that the kidney-tonification compatibility can improve the expression activity and content of BMP2 culture in vitro, with the peak on the 12th day. The kidney-tonification compatibility groups can upregulate expressions of Bmp2, Smad1, Smad4 mRNA. It was concluded that the active ingredient compatibility of kidney-tonification medicine can promote BMSCs. Its mechanism may be related to the upregulation of expression of Bmp2, Smad1, Smad4 mRNA, and the activity and content of Bmp2.

Objective To assess the efficacy of mycophenolate mofetil (MMF) combined with low dose of hormone and lamivudine in the treatment of hepatitis B virus associated glomerulonephritis (HBV-GN).Methods The clinical data of 49 HBV-GN patients diagnosed by renal pathology was reviewed.They were treated with MMF( ≥ 12 years old,0.75 g,two times a day; ＜ 12 years old,0.4 g/m2,two times a day),low dose of hormone [0.5 mg/(kg·d) ],lamivudine( ≥ 12 years old,100 mg/d; ＜ 12 years old,3 mg/kg,two times a day).Results Among of 49 HBV-GN patients,clinical cure rate was 71.4％(35/49),the total effective rate was 81.6％(40/49),85.7％(42/49) patients' HBV DNA level decreased from 5.43 ×104 copies/ml to ＜ 1000 copies/ml.The complete remission rate was 88.0％ (22/25),the partial remission rate was 8.0％ (2/25),the inefficiency was 4.0％ (1/25) in membranous nephropathy (MN);the complete remission rate was 44.4％ (4/9),the inefficiency was 55.6％ (5/9) in mesangial proliferative glomerulone phritis (MsPGN) ; the complete remission rate was 70.0％(7/10); the partial remission rate was 30.0％(3/10)in membrane proliferative glomerulone phritis (MPGN) ;the complete remission rate was 40.0％ (2/5),the inefficiency was 60.0％(3/5) in focal segmental glomerulosclerosts (FSGS).There was significant difference among the different pathological type (P＜0.05).There were less adverse reactions.Conclusions MMF combined with low dose hormone and lamivudine is safe and effective in treating HBV-GN.The efficacy and pathological type has some relationship,MN has the best response,MPGN and MsPGN are second,FSGS is poor.

Basic fibroblast growth factor (bFGF) is a multi-potential growth factor whose biological activities depend on its receptor's intrinsic tyrosine kinase activity and second messengers such as the mitogen activated protein kinases. Heparin sulfate proteoglycans (HSPGs) have been demonstrated to enhance or inhibit bFGF activity. The response elicited by HSPG is related to the relative concentrations and binding kinetics for bFGF of the various pools of HSPG. The type of cellular response might depend on the specific HSPG and FGF receptor expressed on the cell surface. The specific core protein of HSPG, and tissue specific differences in heparin sulfate modification result in altered bFGF regulation.

Objective To study the expression and clinical significance of CD34 and smooth muscle actin (SMA) in stroma of breast tissues and lesions. Methods Seventy cases of breast tissues and lesions, including 20 fibroadenomas, 10 sclerosing adnoses, 30 invasive ductal carcinomas and 10 invasive lobular carcinomas were investigated, and 10 normal breast tissues were served as controls. Immunohistochemical staining was applied to compare the distribution of CD34+ fibrocytes and SMA-reactive myofibroblasts. Results The stroma of normal breast tissue contained CD34+ fibrocytes, whereas SMA-reactive myofibroblasts were absent (100% for both). All benign breast lesions exhibited astromal CD34+ fibrobytes, and fibroadenomas showed SMA-reactive myofibroblasts as well. In invasive ductal and lobular carcinoma the stroma was devoid of CD34+ fibrocytes, but a varying number of stromal SMA-reactive myofibroblasts were detectable (100%). Conclusion In breast carcer, immunohistochemical staining used in detecting expressions of CD34 and SMA is helpful in distinguishing benign lesions from malignancies.

Pg.The adherence activity of periodontal pathogens to HA was enhanced by Ss and Av.When cultivated with Sm,the adherence activity of Pg was reduced.Periodontal pathogens had no effect on the adherence activity of Sm and Av,and Ss excepted. Conclusion The adherence activity of periodontal pathogens is lower than that of cariogenic bacteria.Periodontal pathogens can utilize early-attached bacteria to become those predominant bacteria in periodontal ecosystem.

Results:The correlation coefficient (r)values between GT and BT at 2,4 and 6 mm below alveolar crest were 0.493,0.383 and 0.342 (P <0.001 )respectively,the r value between GT and the distance from CEJ to alveolar crest was -0.21 3(P <0.01 ).No statistically significant difference was observed between CBCT and clinical measurements(t =-0.521 ,P =0.603).Conclusion:There is positive correlation between GT and BT at 2,4 and 6 mm below alveolar crest and negative relation between GT and the distance from CEJ to alveolar crest.

Idiosyncratic adverse drug reactions (IDR) induce severe medical complications or even death in patients. Alert structure in drugs can be metabolized as reactive metabolite (RM) in the bodies, which is one of the major factors to induce IDR. Structure modification and avoidance of alert structure in the drug candidates is an efficient method for reducing toxicity risks in drug design. This review briefly summarized the recent development of the methodologies for structure optimization strategy to reduce the toxicity risks of drug candidates. These methods include blocking metabolic site, altering metabolic pathway, reducing activity, bioisosterism, and prodrug.
