To clarify the active components in Guizhi Fuling capsule in treatment of intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma, main components were gradually knocked out from the capsules, the effects of knockout capsules on uterine contraction, TNF-α secretion, murine splenocytes (SPL) and hysteromyoma cells proliferation were evaluated, respectively. The inhibition of capsules on uterine contraction was weakened by gradient knockout of paeoniflorin, paeonol, and amygdalin. The suppression of capsulte on TNF-α secretion was reduced by gradient knockout of gallic acid, cinnamaldehyde, pentagalloylglucose, and pachyman. The promotion of SPL cells proliferation was reversed by gradient knockout of gallic acid, paeoniflorin, cinnamaldehyde, quercetin, and pachyman. The depression of capsules on hysteromyoma cells proliferation was attenuated by gradient knockout of paeoniflorin, paeonol, pentagalloylglucose, and albiflorin. In conclusion, the compounds mentioned-above could be the key active basis of Guizhi Fuling capsule in treatment of intrinsic dysmenorrhea, pelvic inflammation and hysteromyoma.

Then 36 cell cultures, two PRRSV live vaccine strains and 184 clinical specimens from 52 farms were tested. Five PRRSV field iso-lates were the high virulent PRRSV; two PRRSV live vaccine strains from normal PRRSV, and 123 speci-mens from 42 farmer were positive (only 1 specimen was normal PRRSV). This RT-PCR method proved to be accurate differential diagnosis of the high virulent PRRSV and normal PRRSV with the characteristics of rapidity, sensitivity and specificity, and has a strong clinical relevance.

Objective To investigate the effects of panax notoginseng saponins (PNS) combined with total flavonoids from epimedium (TFE) on testicular dysfunction in natural aging rats; To discuss its mechanism of action. Methods Thirty 18-month old male SD rats were randomly divided into natural aging group, PNS combined with TFE low and high dose groups, with 10 rats in each group. Another 10 2-month old rats were set as young control group. PNS combined with TFE low and high dose groups were given gastric gavage of 10 mg/kg PNS combined with 10 mg/kg TFE, and 20 mg/kg PNS combined with 20 mg/kg TFE, respectively. Rats in young control group and natural aging group were given saline for 6 d each week, lasting for 4 months. Then, rats were sacrificed, and the testes were obtained to calculate the testicular weight and the testicular index. The testicular tissue morphology was observed by using HE staining. Testicular germ cell apoptosis was detected by using TUNEL method. The levels of Bcl-2, Bax and γ-H2 AX protein expression in testicular tissue were detected by Western blot. Results Compared with natural aging group, low and high dose of PNS combined with TFE significantly elevated the testicular weight and testicular index, improved the histological changes of testicular seminiferous tubule, significantly reduced number of apoptosis of spermatogenic cells in the testis, upregulated the expression of Bcl-2 protein in the testis, downregulated the expression of Bax and γ-H2 AX protein, and decreased the ratio of Bax/Bcl-2. Conclusion PNS combined with TFE can improve testicular dysfunction in natural aging rats by inhibiting apoptosis and DNA damage of germ cells.

Objective: To investigate the role of clock gene BMAL1 in exercise-induced skeletal muscle injury recovery. Methods: Two hundred and eight 8-week-old SD rats were randomly divided into the control group (Group C, n=104) and the exercise group (Group E, n=104). Group E performed a 90-minute downhill run on the treadmill. After exercise, the gastrocnemius muscle of 8 rats in Group C and Group E were collected at 0 h, 6 h, 12 h, 18 h, 24 h, 30 h, 36 h, 42 h, 48 h, 54 h, 60 h, 66 h and 72 h. The expression of skeletal muscle core clock gene, BMAL1 was measured by real-time fluorescence quantitative PCR. The parameters of fitting cosine curve were obtained by cosine analysis software circacompare (R package), and the change trend of rhythmic oscillation was analyzed. The ultrastructure of skeletal muscle fibers was observed by transmission electron microscope. The expressions of skeletal muscle BMAL1 and DESMIN were detected by Western blot; Immunofluorescence was used to observe the localization and contents of BMAL1 and DESMIN. Results: In Group C, three complete circadian rhythm cycles of mRNA BMAL1 were observed within 72 hours; in Group E, the circadian rhythm of BMAL1 mRNA disappeared at 0 h～24 h. Compared with Group C, the expression level of BMAL1 mRNA was significantly increased at 0 h, 6 h, 12 h, and 18 h after exercise in Group E (P＜0.05), and the expression of BMAL1 protein was significantly increased at 0 h and 12 h after exercise(P＜0.05), and recovered to the level of that in Group C from 24 h to 72 h(P＞0.05). The expression of DESMIN protein was decreased at 0 h and 12 h after exercise(P＜0.05), gradually increased at 24 h, increased significantly at 48 h(P＜0.01), and recovered to the control level at 72 h (P＞0.05). In Group E, BMAL1 and DESMIN were co-localized at 0 h, 12 h, and 24 h after exercise; the colocalization at 0 h～24 h showed a trend of first decreasing and then increasing, and the fluorescence intensity at 24 h reached the highest value. Conclusion: The post-exercise clock gene BMAL1 may be involved in the enhanced synergy of regulating the cytoskeletal protein DESMIN, it is thus related to the promotion of muscle fiber structure recovery.
