AIM: To establish the method of determining cinobufagin and resibufogenin in Xinkening Capsules(Venenum Bufonis,etc.). METHODS: HPLC was applied to determining cinobufagin and resibufogenin.The determination was carried out using an ODS column with a solvent system: methanol-water(50∶40).The flow rate was 1.0 mL/min,detection wavelength was at 296 nm. RESULTS: The linear ranges of cinobufagin and resibufogenin were 3.5 ?g-0.28 ?g and 3.75 ?g-0.30 ?g,respectively.The average recoveries of cinobufagin and resibufogenin were 99.86%(RSD=1.8%,n=5),and 99.84%(RSD=1.2%,n=5),respectively. CONCLUSION: This method is simple,accurate with strong specificity and can be used to control the quality of Xinkening Capsules.

Objective: To observe the clinical efficacy of warm needling moxibustion plus spine subtle adjusting manipulation for cervical radiculopathy. Methods: A total of 70 patients with cervical radiculopathy were randomized into an observation group and a control group, with 35 cases in each group. The observation group was treated with warm needling moxibustion plus spine subtle adjusting manipulation, while the control group was treated with warm needling moxibustion alone. The treatments were performed three times a week, and for four weeks in total. The visual analog scale (VAS) was scored before and after treatment. And the clinical efficacy of the two groups was compared after treatment. Results: The total effective rate was 97.1% in the observation group, versus 88.6% in the control group. The difference between the two groups was statistically significant (P<0.05). After treatment, the VAS scores in both groups significantly decreased (P<0.01), and the score in the observation group was significantly lower than that in the control group (P<0.05). Conclusion: Warm needling moxibustion plus spine subtle adjusting manipulation has a better effect in the treatment of cervical radiculopathy than warm needling moxibustion alone.

The secondary development of traditional Chinese medicines (TCMs) is an important content of TCM modernization process, as well as an important path for developing new TCM drugs. Under the guidance of the system theory, in response to the lack of the overall guideline and practical methods for the secondary development of TCMs at present, we introduced the overall thought of the secondary development of major TCM varieties, as well as the roles and contents of clinical research, pharmacology and pharmaceutics in the process of the secondary development of major TCM varieties, so as to provide systematic strategies and methods for the development of major TCM varieties.

The secondary development of major traditional Chinese medicine varieties is one of important links during the modernization, scientification and standardization of traditional Chinese medicines. How to accurately and effectively identify the pharmacodynamic material basis of original formulae becomes the primary problem in the secondary development, as well as the bottleneck in the modernization development of traditional Chinese medicines. On the basis of the existing experimental methods, and according to the study thought that the multi-component and complex effects of traditional Chinese medicine components need to combine multi-disciplinary methods and technologies, we propose the study thought of the material basis of secondary development of major traditional Chinese medicine varieties based on the combination of in vivo and in vitro experiments. It is believed that studies on material basis needs three links, namely identification, screening and verification, and in vivo and in vitro study method corresponding to each link is mutually complemented and verified. Finally, the accurate and reliable material basis is selected. This thought provides reference for the secondary development of major traditional Chinese medicine varieties and studies on compound material basis.

Objective To-identify the factors associated with radiation-induced liver disease (RILD) and to describe the probability of RILD using the Lyman normal tissue complication(NTCP) model for primary liver carcinoma(PLC) treated with hypofractionated conformal therapy (CRT).Methods A total of 109 PLC patients treated with hypofractionated CRT were prospectively followed according to the Child-Pugh classification for liver cirrhosis,93 patients in class A and 16 in class B.The mean dose of radi- ation to the isocenter was (53.5?5.5) Gy,fractions of (4.8?0.5) Gy,with interfraction interval of 48 hours and irradiation 3 times per week.Maximal likelihood analysis yielded the best estimates of parameters of the Lyman NTCP model for all patients;Child-Pugh A and Child-Pugh B patients,respectively.Results Of all the patients,17 developed RILD (17/109),8 in Child-Pugh A(8/93 ) and 9 in Child-Pugh B(9/ 16).By multivariate analysis,only the Child-Pugh Grade of liver cirrhosis was the independent factor (P= 0.000) associated with the developing of RILD.The best estimates of the NTCP parameters for all 109 pa- tients were n=1.1,m=0.35 and TD_(50) (1)=38.5 Gy.The n,m,TD_(50) (1) estimated from patients with Child-Pugh A was 1.1,0.28,40.5 Gy,respectively,compared with 0.7,0.43,23 Gy respectively,for patients with Child-Pugh B.Conclusions Primary liver cancer patients who possess Child-Pugh B cirrho- sis would present a significantly greater susceptibility to RILD after hypofractionated CRT than patients with Child-Pugh A cirrhosis.The predominant risk factor for developing RILD is the severity of hepatic cirrhosis in the liver of PLC patients.
