Objective To construct the eukaryotic expression vector containing short hairpin RNA (shRNA) targeting the inhibition of Smad3 gene segment in keloid fibroblasts (KFBs) and to investigate the effects on the expression of Smad7 in KFBs. Methods A couple of the most effective siRNA screened from former experiments were used to recombine the plasmids of Smad3 shRNA, and then Smad3 shRNA was transfected into KFBs by LyoVec TM. The expressions of Smad3 and Smad7 at different time points (0～9 d) were detected by RT-PCR and Western blotting. Results ① The recombinant Smad3 shRNA vectors were identified by RT-PCR and Western blotting. ② The expressions of mRNA and protein of Smad3 in KFBs decreased significantly in a time-dependent manner after transfection of Smad3 shRNA and reached the lowest point at 72 hours in the experimental group. Optical density analysis revealed a significant difference between the experimental group and the control group (P

Objective To explore the significance of serum cystatin C (Cys C)and β2-microglobulin (β2-MG) levels in blood and urine samples in hypertension grading and risk stratifying. Methods One hundred and thirty six cases with primary hypertension were enrolled into the study and classified into three grades and four risk stratifications. The serum Cys C levels were determined by ELISA assay. The blood and urine β2-MG were measured by radioimmunoassay. The serum BUN, Cr concentration were measured by the automatic biochemical analyzer. Results The positive rates of urine β2-MG were the highest index in patients with grade 1 (32%) and low risk hypertension( 8% ) ,followed by serum Cys C levels( grade 1 hypertension 24% ) ,compared with other indices( Ps ＜ 0. 05 ). With the blood pressure elevating, as well as the risk stratification increasing,serum Cys C level and the blood, urine β2-MG levels increased gradually by grading and stratifications (Ps ＜0. 05 or Ps ＜0. 01 ). We also found linear regression relationship between serum Cys C ,urine β2-MG levels and the risk stratifications of hypertension( r =0. 851 and r =0. 469 respectively,Ps ＜0. 01 ). The significant changes of serum BUN,Cr were only found in patients with grade 3 or very high-risk hypertension. Conclusion Joint detection of serum Cys C and urine β2-MG may help to detect early glomerular and tubular dysfunction in primary hypertension patients. Serum Cys C and blood, urine β2-MG levels are also related with the occurrence and development of hypertension,which show clinical significance in hypertension prognosis.

To analyze the composition regularity of Carthami Flos-containing prescriptions of the Drug Standards of Ministry of Health of People's Republic of China-Traditional Chinese Medicine Preparations (the ministerial standards for Traditional Chinese Medicine) based on the traditional Chinese medicine inheritance support system (TCMISS, RZDZ No. 0389952). Efforts were made to identify 331 prescriptions containing Carthami Flos and summarize 16 attending functions and 10 commonly used drug combinations. Three commonly used drug combinations were selected for an in-depth analysis on Carthami Flos's combined administration regularity. Based on Carthami Flos's attending functions, its effects in paralysis, traumatic injuries and dysmenorrheal were compared to analyze Carthami Flos's core drug combinations for treating different diseases. The regularity of clinical administration and the characteristics of commonly used drug combinations were summarized to provide reference for Carthami Flos's clinical application and new ideas for new drug R&D. Carthami Flos prescriptions was mainly used to treat blood stasis and pain and mostly combined with drugs that could activate blood, promote the circulation of qi and dispel pathogenic wind to treat Qi-stagnation and blood stasis caused by various pathogenic factors such as wind, cold and dampness.

Teaching model plays an important role in clinical education. Problem based learning (PBL) model, with an outstanding feature of stimulating the learning enthusiasm of students, was applied by many American colleges. American College of Acupuncture&Oriental Medicine (ACAOM) combined PBL teaching model with traditional lecture based learning (LBL) model, which had achieved good results. In this article, PBL model and its characters were explored via qualitative case analysis, to provide reference for universities and colleges of traditional Chinese medicine on clinical education.

Objective To investigate the expressions of NBS1 mRNA and protein in the salivary gland of irradiated rats and explore the role of NBS1 in the repair of radiation injury of salivary gland epithelial cells.Methods Eighty rats were randomly divided into two groups for radiation and control (n =40 each).The rats were fractionally exposed to 3 Gy of 60Co γ-rays once in two days,leading to an accumulation dose of 3,6,9,12,15 Gy.The sham-irradiated controls were anesthetized in parallel but without irradiation.After 2-4 h of irradiation,the rats were sacrificed,IHC and RT-PCR were used to detect the expressions of NBS1 protein and mRNA in parotid and submandibular glands,and the ultra-structural changes in the glands were observed by a transmission electron microscopy.Results After irradiation,the salivary glands became atrophy and the parotid gland cells were damaged more serious than the submandibular gland cells.Compared with the controls,with the groups of dose,at 9,12,15 Gy in parotid gland (t =7.10,17.93,20.86,P ＜ 0.05),at 12,15 Gy in the submandibular gland (t =3.13,7.53,P ＜0.05),the expression of NBS1 mRNA was reduced.With the groups of dose at 9,12,15 Gy in paretid gland (t =4.29,17.91,91.29,P ＜ 0.05 ),the dose at 12,15 Gy in submandibular gland ( t =4.61,11.84,P＜0.05),the expression of NBS1 protein in serous cells,and the dose at 12,15 Gy in parotid gland ductal epithelial cell ( t =3.09,5.62,P ＜ 0.05) were reduced.But in the ductal epithelial cells as well as muoass cells in the submandibualr gland were steadily.Conclusions After irradiation,NBS1 at both protein and mRNA levels was dropped in the salivary gland of rats,which might contribute to the repair of radiation injury of salivary gland.
