目的 观察HB13对SD大鼠的一般生殖毒性。方法 SD大鼠,雌雄各100只,分为低、中、高剂量组(20、40和80 mg/(kg·d))和对照组(0.5%羧甲基纤维素钠溶液),每组25只。雄鼠于交配前28 d给药,雌鼠于交配前14天给药,给药至妊娠第7天。雄鼠交配后处死,孕鼠于妊娠第14天颈椎脱臼处死,观察HB13对雌雄鼠一般情况、生育力和胚胎发育的影响。结果 与对照组相比,HB13高、中剂量组雄鼠给药期体重减轻,睾丸系数及附睾系数增大,异常精子率升高;高剂量组还使雄鼠生育力降低。给予高、中剂量HB13的雌鼠妊娠后体重较对照组减轻,着床后丢失率增高,吸收胎数增加,活胎数减少,连胎子宫重降低;高剂量组HB13还使雌鼠生育率及着床数降低,着床前丢失率升高。结论 HB13低剂量对雌、雄性大鼠无一般生殖毒性;中剂量对孕鼠早期胚胎发育有明显干扰作用;高剂量对雌、雄大鼠生育力有显著降低作用并且对早期胚胎发育有明显干扰作用。

Objective To study the general reproductive toxicity of HB13 in SD rats. Methods SD rats, 100 females and 100 males, were divided into low, medium and high dose groups 20, 40 and 80 mg/(kg·d) and the control group (0.5% CMC-Na), The rats were given HB13 for 28 days in male rats and 14 days in female rats respectively before mating, and then mated. The HB13 treatment continued until the 7th day of pregnancy. When the female rats were confirmed pregnant, the male rats were executed and the female rats were executed on the 14th day of pregnancy. Then we can observe the effect of HB13 on fertility and embryonic development in rats. Results Compared with the control group, the body weight of medium, high dose group reduced significantly, the coefficient of testicular and epididymis, abnormal sperm rate increased significantly. High dose group of HB13 also made the fertilityof male rats decline; The body weight, live births uterus weight (including the fetus) of pregnant rats in high and medium group decreased significantly. At the same time, the rate of lost oosperm and absorbed embryo increased. The high dose group of HB13 can also reduce the fertility of female rats. Conclusion The low dose group of HB13 didn't have general reproductive toxicity in rats, the medium dose group impaired early embryonic development, but the high dose group can significantly reduce the fertility of both male and female rats, and can impair the development of embryonic.

Objective To retrospectively investigate the influence of Shenyi Capsule maintenance therapy on inflammatory factors in patients with advanced NSCLC. Methods Thirty seven patients with advanced NSCLC, who had become palliative or stable after first-line treatment with combined Shenyi capsule chemotherapy, were intentionally assigned to treatment group (group A, 21 patients) and control group (group B, 16 patients). Shenyi capsule was given to group A (20mg p.o., bid) until appearance of deterioration or intolerance, while no special treatment was given to group B. Leukocytes, neutrophils, C-reactive protein, tumor necrosis factor α (TNF-α), interleukin-1β(IL-1β), interleukin-1α (IL-1α),interleukin-6(IL-6) and interleukin-10(IL-10) were tested by blood specimens taken respectively on 1st day and 90th day. Results There were no statistical differences (P>0.05) between the level of inflammatory factors on 1th day and 90th day in treatment group. In control group, however, TNF-α、IL-1β and IL-6 increased (P<0.001, P=0.032、P=0.001 respectively) and IL-10 decreased significantly (P=0.035). Furthermore, the level of TNF-α、IL-1β and IL-6 in treatment group were also higher (P<0.001, P=0.001, P=0.004 respectively), while IL-10 was lower (P=0.002)than control group on 90th day. There were no statistical differences(P>0.05)between the two groups in the level of IL-1α, leukocyte, neutrophils or C reactive protein on 1th day and 90th day. Conclusion Shenyicapsule maintenance therapy could lower the expression of TNF-α、IL-1β and IL-6 in patients with advanced NSCLC, which indicates that the regulation of inflammatory reaction may be one of the mechanisms of inhibition from NSCLC progression in Shenyi capsule maintenance therapy.

Objective To explore the application value of color Doppler ultrasound in patients with azoospermia who underwent testicular needle biopsy. Methods Retrospective analysed the clinical data of 53 cases patients with azoospermia from 2012 November to 2015 February in our department.All patients underwent routine scrotal ultrasonography, to detecte the peak systolic velocity (PSV), end diastolic velocity (EDV) and resistance index (RI) of testicular artery (TA)and intratesticular artery (ITA)with spectral Doppler ultrasound. Color Doppler ultrasound was used to observe the distribution and the number of blood vessels in the testicle, and semi quantitative score. All patients underwent testicular biopsy and Johnsen score. Results 47 patients were diagnosed as obstructive azoospermia(OA), 6 patients were diagnosed as non obstructive azoospermia(NOA). The average volume of testis was (15.3±3.6)mL in 0A group. The average volume of testis was (7.1±2.8) mL in N0A group.There was significant difference (P<0.01). The blood flow parameters(PSV, EDV, RI) results between OA group and NOA group have obvious difference,the difference was statistically significant (P<0.05). The semi quantitative classification of testicular vessels between OA group and NOA group have obvious difference,the difference was statistically significant (P< 0.01). Conclusion Color Doppler ultrasound is a good predictor of testicular spermatogenic function, can be used as the identification index of patients with OA and patients with NOA.

Objective The aim of this study was to explore induction and differentiation of endogenous neural stem cells(ENSCs) in the hippocampus soluble factors(HSF) from the hippocampus of adult Wistar rats by mimicking an intracranial microenvironment. Methods After Wistar rats sacrificed, the hippocampus tissue was obtained in cold DMEM/F12. After centrigued and filtered, the HSF was stored at -20℃. The ENSCs was obtained from the hippocampus tissue of a neonate Wistar rat. Collected the tissue, digested and obtained the ENSCs. After we observed the morphology, the ENSCs were cultured in different concentration (0、50、100、200、400 μl/mL) of HSF for 6 days, and compared the expression of Nestin and CD133 by immunocytochemistry. Meanwhile,we compared the Nestin and CD133 protein by western blot. And then we explored the optimal concentration of HSF by the numbers of all groups on the second and sixth day. Furthermore, we did the differentiated experiment using the same concentration of HSF. Results The number of neurospheres in the 100 μg/mL group was significantly higher than those in the other groups on the 6th day. Immunofluorescence revealed that the neurospheres from ENSCs in the 100 μg/mL group more highly expressed nestin and CD133 than control. This result was confirmed by western blot analysis. The neurospheres can differentiate into glia-like cells in 100 μg/mL HSF and 1% FBS expressing GFAP, S100 and P75 NGFR by immunofluorescence. Conclusion These data indicated that HSF alone, mimicking a destination of ENSCs in vitro, could induce and differentiate neurospheres from ENSCs, as a new method to get NSCs and glia-like cells differentiated from ENCs to repair the diseases of center nervous system.
