The heel vessel belongs to the eight extra meridians in human meridian system, which is closely related to the human motion function. Balance function plays an essential role in successful completion of activities in daily life, so the physiological function and pathology of heel vessel as well as human balance function are analyzed, and from the aspect of running course of heel vessel and syndrome, the correlation between heel vessel and human balance function is explored, and the application status of acupoints related to heel vessel for balance dysfunction is introduced. It is believed that heel vessel is closely related to human balance function, especially the motion regulation mechanisms of balance function, and it is hoped that new ideas and methods can be provided for acupuncture treatment for the balance function disorders.

BACKGROUND:Bone marrow mesenchymal stem cells can differentiate into osteoblasts under inducing condition that Zouguiwan and Youguiwan coordinate inducers, but the mechanism remains to be discussed. OBJECTIVE:To observe the effects of serum containing Zuoguiwan and Youguiwan on transforming growth factorβ1 and its signal transduction protein Smad2/3 message expression during the osteogenic differentiation of bone marrow mesenchymal stem cells. METHODS:A whole bone marrow adherence method was adopted to isolate and cultivate bone marrow mesenchymal stem cells from rats. The cellcultivation was processed in five groups:bone marrow mesenchymal stem cells were respectively cultured with blank serum, serum containing Zouguiwan, serum containing Youguiwan, positive serum containing progynova+inducer (dexamethasone, vitamin C, andβ-glycerophosphate), and inducer. Western blot was applied to detect the expression of type I col agen. The immunohistochemical assay was utilized to test transforming growth factorβ1 and Smad2/3 expression in the osteoblasts. RESULTS AND CONCLUSION:It was apparently more significant for serum containing Zuoguiwan and Youguiwan on type I col agen, transforming growth factorβ1 and Smad2/3 expression, compared with blank serum group and inducer group (P<0.05);moreover, serum containing Zuoguiwan was better than serum containing Youguiwan (P<0.05). Both of serum containing Zuoguiwan and Youguiwan are able to promote osteogenic differentiation of bone marrow mesenchymal stem cells. Moreover, Zuoguiwan is much more effective indicating that this method of traditional Chinese medicine about nourishing kidneys can be better to promote osteogenic induction of bone marrow mesenchymal stem cells.

Objective To investigate the factors associated with postoperative metastasis, recurrence, and survival in patients with stage ⅢA ( N2 ) non?small cell lung cancer ( NSCLC ) , and to provide an objective basis for postoperative radiotherapy in patients. Methods Clinical data were collected from 199 patients who underwent complete resection and were diagnosed with stage ⅢA ( N2 ) NSCLC after surgery in our hospital from 2009 to 2013. The Cox regression model was used for the multivariate analyses of metastasis and recurrence. The survival rates were calculated using the Kaplan?Meier method and analyzed using the log?rank test. Results In the 199 patients, 173 had complete follow?up data. The 1?and 2?year metastasis, recurrence, and survival rates were 38?7%/52?6%, 27?8%/39?1%, and 92?5%/51?4%, respectively. The multivariate analysis showed that pathological type and two positive indices among preoperative CEA/CY211/SCC were two risk factors for metastasis ( P=0?013,0?014) . Positive lymph node number, metastatic lymph node number, lymph node metastasis rate, and two positive indices among preoperative CEA/CY211/SCC were risk factors for recurrence ( P=0?046,0?004,0?028,0?001) . All the above indices were risk factors for low survival rates ( P= 0?013 , 0?011 , 0?002,0?026 ) . Conclusions Patients with stage ⅢA ( N2 ) NSCLC who have positive lymph nodes, lymph node metastases, and two positive indices among preoperative CEA/CY211/SCC may benefit from postoperative radiotherapy.

Twelve novel 2-phenyl -tetrahydrothiopyrano［4, 3-d］pyrimidine derivatives were synthesized from 4-hydroxy-benzonitrile by etherification, hydrolysis, acylation and addition reactions, etc. The inhibitory activities against xanthine oxidase were evaluated in vitro. Results showed that compounds 8a-8h exhibited varying inhibitory potencies on xanthine oxidase at 100 μmol/L, significantly better than those of compounds 6a-6d, indicating that carboxy-substituted pyrimidine is beneficial to the inhibitory activity. Among compounds 8a-8h, 8f with isopropionic acid-substituted pyrimidine and ethyl-substituted phenol showed the best inhibition with IC50 of 76. 0 μmol/L.
