The metabolism study of radiolabeled drugs plays an important role in the development of new drugs. It provides information on drug absorption, metabolism, tissue distribution and excretion, and plays an irreplaceable role in the metabolite safety evaluation and mass balance of new drugs. The new guidance draft on clinical trials of radiolabeled drugs recently released by the US FDA puts forward higher standards and has been widely concerned by the industry. In recent years, in the research and development of new drugs in China, 14C labeled drugs have been used to carry out clinical metabolism studies, which has overcome key technical bottlenecks and accumulated experience. This paper summarizes the above research progress, analyzes the existing problems, and preliminarily looks forward to the future technological development and application.

Objective To evaluate the role of gamma curve fitting technique of contrast-enhanced ultrasound in quantitative analysis of microcirculation in renal solid lesions. Methods A total of fifty patients with renal parenchyma solid lesions were performed contrast-enhanced ultrasound. The images were analysed by computer with gamma fitting analysis of contrast-enhanced ultrasonic system. The quantitative parameters were obtained by the time-intensity curves, such as ascending slope (a3), descending slope (a2), arrival time (AT), time to peak intensity (TTP), basic intensity (BI), peak intensity, amplification (AMP), area under the curve (AUC), mean transit time (MTT) and perfusion index (PI). The parameters were compared between renal malignant and benign solid lesions. Results Fast-in and fast-out was the main perfusion mode in renal malignant tumors while slow-in and slow-out was found in renal angiomyolipoma (AML). The perfusion modes in renal malignant tumors and renal AML were fast-in and fast-out in 28 cases and 0 case, fast-in and slow-out in 4 cases and 1 case, slow-in and fast-out in 5 cases and 1 case, and slow-in and slow-out in 1 case and 10 cases, respectively. There were significant differences in the quantitative parameters such as a2, AUC and PI between renal malignant tumors and renal AML obtained by the time-intensity curves (P<0.05). Conclusion Gamma fitting analysis of contrast-enhanced ultrasound system can provide quantitative information of microcirculation of renal tumors, which helps to differentiate benign renal tumors from malignant ones.

OBJECTIVETo observe analgesic effect of electroacupuncture ( EA) on rats with chronic inflammatory pain and its regulatory mechanism on ispilateral dorsal root ganglion (DRG) and spinal dorsal horn (SDH) Mas-related G protein-coupled C receptor (MrgprC).
METHODSTotally 40 healthy male SD rats were divided into 4 groups according to random number table, i.e., the normal (N) group, the model (M) group, the acupuncture (Acu) group, the EA group, 10 rats in each group. The model of chronic inflammatory pain was established by subcutaneous injecting 0. 1 mL complete Freund's adjuvant (CFA) into right hind paw. Paw withdrawal thresholds (PWTs) were measured before modeling, at day 1, 3, 5, 7, and after CFA injection, respectively. Expression levels of MrgprC in ispilateral DRG and SDH were detected by Western blot. The content of bovine adrenal medulla 22 (BAM22) in SDH was detected by immunohistochemical assay.
RESULTSCompared with N group at each time point, PWTs significantly decreased in M group (P <0. 01). Compared with M group, PWTs significantly increased at day 5 of EA and after EA in EA group (P < 0.05, P < 0.01). Compared with Acu group at each time point, post-EA PWTs significantly increased in the EA group (P < 0.05). Compared with N group, expression of MrgprC in ispilateral DRG and ratio of BAM22 positive cells in ispilateral SDH increased in M group (P < 0.01). Compared with M group, expression of MrgprC in ispilateral DRG and ratio of BAM22 positive cells in ispilateral SDH increased in the EA group (P < 0.05).
CONCLUSIONEA had favorable analgesic effect on chronic inflammatory pain induced by CFA, and its mechanism might be possibly associated with up-regulating MrgprC expression in ispilateral DRG and BAM22 content in ispilateral SDH.

Objective To observe the clinical efficacy of acupuncture combined with acupoint injection for treatment of patients with intractable hiccups and to seek its standard therapeutic regimen. Methods A prospective study was conducted. Eighty-six patients with intractable hiccups in various clinical departments in the First Affiliated Hospital of Xinjiang Medical University met the inclusion criteria of this study were selected,and according to the different treatment options they were divided into observation group and control group with 43 cases in each group. In the observation group,on the basis of treatment for their primary diseases,the rules of soothing the chest oppression and regulating the flow of qi(Kuanxiong Liqi)and regulating the stomach and sending down abnormally ascending qi(Hewei Jiangni)were followed in treatment,and acupuncture was carried out at Danzhong,Neiguan(double=bilateral acupoints),Zusanli(double),Sanyinjiao(double),Taichong(double)with the needle staying for 20 minutes each time,1 mL metoclopramide injection was injected at each of the bilateral Zusanli acupoints,once a day. In the control group,the patients received intramuscular injection of 10 mg metoclopramide once a day. Both groups were treated for consecutive 7 days. After treatment for 3 days and 5 days,the clinical efficacy was observed,and before treatment and after treatment for 3,5,7 days,the changes of hiccups frequency and persistent duration were investigated. Results Compared with the control group,the total effective rates in observation group on the 3rd and 5th day after treatment were significantly increased〔3 days:88.4%(38/43)vs. 51.2%(22/43),5 days:95.3%(41/43)vs. 62.8%(27/43),both P<0.01〕. With the prolongation of therapy,the hiccups frequency was gradually decreased and the persistent duration of hiccup was gradually shortened,reaching the lowest degree on the 7th day after treatment,and the changes were more significant in the observation group〔hiccups frequency(times/day):0.57±0.08 vs. 2.04±1.78,hiccup duration time(minutes/time):1.07±0.68 vs. 9.23±5.69,both P<0.05〕. Conclusion The therapeutic effects of acupuncture combined with acupoint injection for treatment of patients with intractable hiccups are superior to signal western medicine therapy.
