Seven target compounds coupled by rhein and furoxan were synthesized and their chemical structures were confirmed by 1H NMR, IR, and MS. All target compounds were evaluated for anti-proliferative activity against human hepatoma cells HepG2 and Bel-7402, human colon cancer cells HCT116, human osteosarcoma cells U2OS, drug-resistant cells Bel-7402/5-FU and normal hepatocytes cells LO2 in vitro by thiazolyl blue(MTT) colorimetry. The results indicated that all target compounds had more potent anti-proliferative activity than their parent compound rhein. Additionally, compound 4g had stronger proliferation inhibitory activity on HepG2, Bel-7402, U2OS and Bel-7402/5-FU,with little effect on the proliferation of normal cells, exhibiting selective inhibitory activity. Griess assay was used to measure the release of nitric oxide in vitro. Results showed that compound 4g could increase the releases NO in HepG2 cells, which may be associated with its antitumor effects. Furthermore, the antitumor activity of compound 4g was attenuated by NO scavenger (hemoglobin), which indicates that the antitumor activity of compound 4g may be partly related to the release of NO.

Objective To observe the effect of Compoud Qingqin Liquids on renal function of rat model of uric acid nephropathy, and to discuss its protection of renal function. Methods The rat model was induced by gavaging adenine and feeding yeast. SD rats were randomly divided into control group, model group, positive group, and high-, medium-, low-dose groups of Chinese medicine. Blank control group and model group were daily gavaged with distilled water, positive control group was daily gavaged with allopurinol by 9.33 mg/kg, and high-, medium-, low-dose group of Chinese medicine was daily gavaged with Compound Qinggin Liguids by 3.77, 1.89, 0.09 g/(kg·d) respectively for 6 weeks. General condition of rats were observed, renal pathological changes were observed with light and electron microscope. Urine protein concentration, blood uric acid, blood urea nitrogen, creatinine and kidney weight index were respectively tested before and after treatment. Results There were no significant differences in eating, drinking and body weight between before and after modeling. Compoud Qingqin Liquids can obviously decrease the concentration of urine protein, blood uric acid, serum creatinine, blood urea nitrogen, and kidney weight index (P<0.05) of rats with uric acid nephropathy. Renal tubular epithelial cells atrophy and renal interstitial fibrosis of high-dose group of Chinese medicine were not evident. Conclusion Compoud Qingqin Liquids can protect the rats renal function against uric acid renal injury.

Objective To analyze the characteristics of medial sural artery perforator (MSAP) flap, and to ex-plore the practicality of repair of small and medium-sized defects of dorsum pedis with the flap. Methods Between March, 2012 to December, 2015, 12 patients with variable defects of 4.0 cm×3.0 cm to 4.0 cm×6.0 cm underwent MSAP flap reconstruction. There were 7 males and 5 females, aged from 19 to 49 years (mean, 32 years). The disease causes were crush injury in 6 cases, machine saw injury in 5 cases, and hot crush injury in 1 case. The size of flaps ranged from 4.0 cm × 5.0 cm to 5.0 cm×7.0 cm. All of the donor site was sutured directly. Postoperative follow up was done termly. Results All 12 flaps survived. The flap was similar to the surrounding normal skin, and all patients returned to ambulation. Eleven cases survived without a hitch, the other 1 of venous congestion was salvaged by venous thrombectomy and reanastomosis. Fol-lowed-up 5-24 months postoperative, the color of the flap was similar to the surrounding skin. All patients recovered walk-ing and shoe wearing function. The calf residual linear scar. Conclusion The MSAP flap provides thin soft tissue cover-age, enabling good functional recovery after defect reconstruction dorsum of forefoot, show the evident advantages.

Objective To observe the protective effect of Tangshenqing Formula II ( TSQF) on the renal function of mice with type 2 diabetes mellitus ( DM) . Methods KK-Ay mice, a spontaneous DM mod-el, were fed with fat-enriched diet for three weeks. Based on their serum glucose ( Glu) and body weight ( BW) , the mice were divided into model group, valsartan group, high, middle, and low dose of TSQF ( high-, mid-, low- dose ) group ( n =6 each ) and were treated for consecutive 12 weeks. And six C57BL/6J mice were included into control group. At the timepoint of Week 0, 4, 8, 12, Glu, urine al-bumin ( Alb) , urine creatine ( Cr) , Alb/Cr( ACR) and 24-h urine protein ( pr/24 h) were detected. At the end of Week 12, all the mice were sacrificed and their serum samples were collected. And the serum levels of TG, TC, Scr, BUN and β2-MG were measured. Results Compared with the control group,
the levels of pr/24 h, ACR, Scr, TG and TC in the model group significantly increased ( P<0. 05 or P<0. 01), While BUN,β2-MG and ratio of kidney weight to body weight showed no statistcal differences (P>0. 05). Compared to the model group, the levels of Scr, TG and ACR in valsartan group and three TSQF groups significantly decreased (P<0. 05 or P<0. 01), and those of TC, Glu, and pr/24 h de-creased at different degree. Conclusion TSQF could reduce the serum levels of Glu, Scr and TG of kk-Ay mice, and alleviate the kidney injuries to reduce the progression of diabetic nephropathy.

The current ear is a time of agriculture civilization, industrial civilization and information intelligence in parallel.In this time traditional Chinese medicine (TCM) is much valued but it is still in an opportunity period of transformation from a vulnerable science.TCM development should comply with development direction of big science, and keep pace with the times based on image thinking and original creativity.Aiming at 2 important issues in medical development-medical moral education and clinical research, the authors propose that the characteristics of high concept age should be grasped, medical ethics should be remodeling according to benevolence and virtue concepts, humanistic care should be blended in medicine, innovative academic team should be built, and harmonious academic atmosphere should be constructed.Medical research should be based on clinical practice, and clinical practice should be guided by original derivation and development of sciences.The talents of general medicine should be cultivated through early and frequent clinical practice.Basic and clinical researches should be guided by TCM original thinking.It is historical inevitability to integrate TCM and Western medicine.The update of disciplinary framework should be mobilized by curative effect of TCM pattern differentiation and treatment, and medical system will be completed with philosophic wisdom of Chinese ethnic peoples.

Cytochrome P450 1A (CYP1A), one of the major CYP subfamily in humans, not only metabolizes xenobiotics including clinical drugs and pollutants in the environment, but also mediates the biotransformation of important endogenous substances. In particular, some single nucleotide polymorphisms (SNPs) for genes may affect the metabolic ability of endogenous substances, leading to some physiological or pathological changes in humans. This review first summarizes the metabolism of endogenous substances by CYP1A, and then introduces the research progress of SNPs, especially the research related to human diseases. Finally, the relationship between SNPs and diseases is discussed. In addition, potential animal models for gene editing are summarized. In conclusion, CYP1A plays an important role in maintaining the health in the body.

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.
