In the genealogical investigation into 1210 patients with alopecia areata(AA), we found 75 cases with a positive family history of AA, the familial incidence was 6.2%. The incidence of AA in the 75 families (1093 cases) was 14.91% (163 cases). In these families, there were 142 patients in first-grade relatives of the family members, 17 in second-grade, and 4 in third-grade. We observed 70 cases in 33 families within one generation, 87 cases in 40 families within two succesive generations, and 6 cases in 2 families within three successive generations, four pairs of monozygotic twins appeared in this investigation, but just one of each pair was affected. The relationship between pathogenesis of AA and genetic factor has been discussed.

AIM: To establish an LC-MS/MS method for determination of evodiamine concentration in rat plasma and to study its pharmacokinetic profile in rats. METHODS: Six rats were administrated (i.g.) evodiamine at the dose of 100 mg/kg. Blood samples were collected from eye socket. Evodiamine concentration in rat plasma was determined by LC-MS/MS method. The pharmacokinetic parameters were calculated using DAS program. RESULTS: A good linear relationship was obtained in the concentration range (0.2-50.0 ng/mL) studied (r2=0.9997). Average recoveries ranged from 96.12% to 99.46%. Intra-and inter-day relative standard deviations were 4.61%-13.51% and 5.65%-11.49%, respectively. The main pharmacokinetic parameters of evodiamine were as follows: Cmax (5.3±1.5) ng/mL; tmax (22±8) min; t1/2 (451±176) min. CONCLUSION: A selective and sensitive liquid chromatography-tandem mass spectrometric (LC-MS/MS) method for the quantification of evodiamine in rat plasma is developed and validated. This method is successfully applied for the pharmacokinetic studies of evodiamine in rats.

AIM: To determine the concentration of escitalopram in human plasma by HPLC-MS/MS and investigate the pharmacokinetics of escitalopram. METH-ODS: The method involved protein precipitation with methanol. The chromatographic separation was achieved within 6.0 min by using methanol-water with 15 mmol·L-1 ammonium acetate-formic acid (72:28:O.1, v/v/v) as mobile phase and a Lichrospher CN 150 mm×4.6 mm analytical column. The analytes were detected using an electrospray ionization tandem mass spectrometry in SRM mode. Detection of the ions was performed by monitoring the transitions of m/z 325.0 to 234.0 for escitalopram and m/z 409.1 to 238.1 for amlodipine (intemal standard), respectively. RESULTS:The standard curve was linear ( r = 0. 999) over the concentration range of 0.20 - 50.00 ng· ml- 1. Accuracy and precision were below the acceptance limits of 15%. The recoveries of escitalopram ranged from 96.0% to 103.6%. The lower limit of quantification for escitalopram was 0.20 ng· ml-1 using 200 μl plasma sample.The pharmacokinetic parameters of escitalopram after a single oral dosing of escitalopram oxalate tablet (10 rog)to ten healthy male volunteers were achieved. The Cmax, Tmax, AUC0-t, AUC0-∞, t1/2 and Ke of escitalopram were 9.21±2.10 ng·ml-1 , 3.75±1.04 h, 514.6±152.3 ng·h·ml-1 ,540.5±162.3 ng·h·ml-1 , 34.06±7.71 h and 0.021±0.004 h-1,respectively. CONCLUSION:The determination of concentration of escitalopram in human plasma by HPLC-MS/MS method was repid, sensitive and reliable. It can be used for clinical pharmacokinetic study of escitalopram.

Objective To analyze and compare efficacy and safety of different chemotherapy regimens in the treatment of elderly patients with advanced gastric cancer. Methods 60 elderly patients admitted to our hospital with advanced gastric cancer were selected as research subjects , and divided into experimental group and control group depending on the treatment of chemotherapy. The experimental group were treated with Gio oxaliplatin (SOX), and patients in the control group accepted Olivier Elizabeth, leucovorin and fluorouracil (FOLFOX6) treatment. Compare and analyze the efficacy of the two groups after two cycles of therapy. Results By chemotherapy, recent efficiency and disease control rate were not significantly different (P>0.05) between the two groups;and there was also no significant difference in the incidence of adverse reactions,such as adverse reactions, fatigue weakness, gastrointestinal reactions, hand-foot syndrome, oral mucositis (P > 0.05). Conclusion The efficacy was equivalent between FOLFOX6 chemotherapy SOX test group and the control group in the treatment of elderly patients with advanced gastric , and there was no significant difference in the incidence of adverse reactions.

The curcumin prodrugs, which could be selectively activated in tumor cells, were prepared to establish a basis for the targeted chemotherapy for cancer. On the basis of the molecular structure of curcumin, the N-maleoyl-L-valine-curcumin (NVC), N-maleoyl- glycine-curcumin (NGC) were chemically synthesized and identified by IR and NMR spectroscopy. After treatment with these two prodrugs for 6 - 24 h, the rates of growth inhibition on human bladder cancer EJ cells and renal tubular epithelial (HKC) cells were detected by MTT colorimetry. Our results showed that after the treatment with 20 micromol/L - 40 micromol/L NVC and NGC for 6 - 24 h, the growth inhibitory effects on EJ cells were 6.71% - 65.13% (P < 0.05), 10.96% - 73.01% (P < 0.05), respectively, in both dose- and time-dependent manners. When compared with the curcumin of same concentrations, the growth inhibitory effects of these two prodrugs on HKC cells were significantly decreased (P < 0.01). It is concluded that activation of curcumin prodrugs via hydrolysis functions of cellular esterase could inhibit the growth activities of tumor cells, and reduce the side effects on normal diploid cells. This provided a novel strategy for further exploration of tumor-targeted chemotherapeutic drugs.
