In this study, UPLC-MS/MS was adopted to determine the contents of five ephedrine alkaloids (Norephedrine, Norpseudoephedrine, Ephedrine, Pseudoephedrine, Methylephedrine) in plasma and urine in rats after the combined administration of Ephedrae Herba-Gypsum Fibrosum and calculate relevant pharmacokinetic parameters, in order to discuss the effect of the combined administration of Ephedrae Herba-Gypsum Fibrosum on plasma pharmacokinetics and urinary excretion characteristics. According to the results, after being combined with Gypsum, the five ephedrine alkaloids showed similar pharmacokinetic changes, such as shortened t(max), accelerated absorption rate, but reduced AUC(0-t) and V(z)/F, which may be related to the increase in urine excretion. Besides, Gypsum was added to enhance C(max) of Pseudoephedrine and prolong MRT(0-t) of Methylephedrine, so as to enhance the anti-asthmatic effect of Ephedrae Herba and resist the toxic effect of Norephedrine and Ephedrine. This study proved the scientific compatibility of Ephedrae Herba-Gypsum Fibrosum and provided a reference for studies on the prescription compatibility regularity and relevant practices.

Objective To analyze the mortality and influencing factors of hepatobiliary cancer patients using the death data of hepatobiliary malignant tumors of Yangpu District, Shanghai, from 1974 to 2015. Methods Joinpoint regression was used to analyze the mortality trend of hepatobiliary cancer. Age-period-cohort (APC) model was employed to evaluate the effects of age and cohort factors on the mortality rate of hepatobiliary cancer. Results From 1974 to 2015, a total of 9 866 liver cancer deaths were reported in Yangpu District, with a male to female ratio of 2.7:1; and the crude mortality rate and standardized mortality rate were 23.09/100 000 and 18.87/100 000, respectively. A total of 2 173 biliary tract cancer deaths were reported, with a male to female ratio of 1:1.7; and the crude mortality rate and standardized mortality rate were 5.04/100 000 and 3.82/100 000, respectively. Joinpoint regression analysis showed that the standardized mortality rate of liver cancer decreased from 1974 to 2015, while that of biliary tract cancer increased. In APC model, the overall mortality risk of liver cancer and biliary tract cancer increased with the increase of age. The mortality rates of liver cancer and biliary tract cancer were increased in the population born before 1930. The mortality rates of the male liver cancer and the male and female biliary tract cancer were decreased in the population born between 1930 and 1949. The mortality rate of liver cancer was increased in the females born after 1949. Conclusion From 1974 to 2015, the mortality rate of liver cancer has a decreasing trend in Yangpu District, Shanghai, and the mortality rate of male is higher than that of female. The mortality rate of biliary tract cancer shows an increasing trend, and the mortality rate of female is higher than that of male. The mortality rates of liver cancer and biliary tract cancer associated with aging factors have increased. Exposure factors have a consistent effect on liver cancer and biliary tract cancer, which may be related to socioeconomic factors at that time.

In this study, the COI barcode was used to identify the Scolopendra medicinal materials and its adulterants in order to provide a new method for the identification of Scolopendra. Genomic DNA was extracted from the experimental samples. The COI sequences were amplified and sequenced bi-directionally. Sequence alignment and NJ tree construction was carried out by MEGA6.0 software. The results showed that the COI sequences can be obtained from all experimental samples. The average inter-specific K2P distance of Scolopendra was 0.222 and the minimum inter-specific distance was 0.190. All the Scolopendra subspinipes mutilans medicinal samples clustered into a clade in the NJ tree and can be distinguished from its adulterants. In a conclusion, COI can be used to correctly identify Scolopendra medicinal materials, and it will be a potential DNA barcode for identifying other animal medicinal materials.

OBJECTIVETo study the effect of Guishen Pill (GSP) on expression levels of Oct-4, MVH, and Egr-1 in mice with diminished ovarian reserve (DOR).

METHODSTotally 40 female C57BL/6J mice were randomly divided into 4 groups, the normal control group, the model group, the GSP group, and the dehydroepiandrosterone (DHEA) group, 10 in each group. Pregnant mare serum gonadotropin (PMSG), human chorionic gonadotropin (HCG), and prostaglandin F2α (PGF2α) were sequentially administrated to produce superovulation. The DOR model was established by exposing to ozone inhalation. Mice in the GSP group were intragastrically administered with GSP at 0.3 mL. Those in the DHEA group were intragastrically administered with DHEA at 0.3 mL. Equal volume of normal saline was intragastrically administered to mice in the normal control group and the model group. All mice wer treated for 21 days. Serum levels of estrogen (E2), progestogen (P), and anti-Müllerian hormone (AMH) were measured by ELISA. Changes of Oct-4, anti-AMH, and early growth response gene-1 (Egr-1) mRNA in ovaries were dtected by Real-time PCR.

RESULTSCompared with the model group, serum levels of E2, P, and AMH, as well as contents of estrogen receptor (ER), progestogen receptor (PR), MVH, and Oct-4 mRNA significantly increased in the GSP group and the DHEA group (P < 0.05).

CONCLUSIONGSP could improve expression levels of Oct-4, MVH, and Egr-1 mRNA in DOR mice and their ovarian function.

Objective To investigate the uptake of 99Tcm-hydrazinonicotinamide-D-alanine-D-alanine-alanine-proline-arginine-proline-glycine (HYNIC-A(D) A(D) APRPG) in rabbit models of inflammation and VX2 tumor xenografted, so as to evaluate its use as a new tracer for tumor angiogenesis. Methods Ten rabbit models of xenoplanted VX2 tumor and inflammation were randomly divided into two groups which were injected with different injected tracers, 99Tcm-HYNIC-A(D) A (D)APRPG 99Tcm-RGD, followed by serial Gamma images at various time points. The first group underwent 18F-FDG PET ahead of 99Tcm-HYNICA(D)A (D) APRPG SPECT. Analysis of variance and t-test were performed with SPSS 10.0. Results 99TcmHYNIC-A(D) A (D)APRPG scan showed negative uptake at inflammation focus but positive uptake at tumor. Pathological examination confirmed high 99Tcm-HYNIC-A(D)A(D) APRPG accumulation in tumor cells, with the highest tumor/inflammation ratio (3.25 ±0. 171) at 2 h post-injection, which was significantly higher than that of 99Tcm-RGD (2.37 ± 0.076) (F = 15. 63, P<0. 01). The tumor/inflammation ratios of 99Tcm-HYNIC-A(D)A(D)APRPG, 99Tcm-RGD, 18F-FDG were significantly different at 0.5, 1,2,3, 6 h (F = 13. 83～26. 41; t = 23.84, 12.75; all P<0. 01). Conclusion 99Tcm-HYNIC-A (D) A (D)APRPG can be used as a potential tracer for tumor angiogenesis.
