Fifteen novel 5-substituted-2-(pyridyl)benzothiazole compounds were designed and synthesized by simple hydrolization and condensation reaction of the 2-amino-5-substituent benzothiazole. Activities of these synthesized compounds were evaluated on Bcap-37, HCT-15 and HepG2 tumor cells in vitro by standard MTT assay. 5-Fluorouracil (5-FU) was used as the positive control. The results revealed that most of the new compounds had potent effects on Bcap-37, HCT-15 and HepG2 tumor cells, and had no or less effect on 293T and L02 normal cells. Particularly, compounds 1c and 2e exhibited better activities on HCT-15 and HepG2 cells with IC50 values of 41.59 and 38.65 micromol x L(-1), and 1i showed excellent activities on Bcap-37 and HepG2 cells with IC50 values of 46.63 and 23.51 micromol x L(-1), respectively. The structure-activity relationship of 5-substituted-2-(pyridyl)benzothiazole compounds were also discussed preliminarily.

Objective To explore the effect of estrogen on striatal neurons damage in rats induced by quinolinic acid (QA).Methods Ovariectomized rats were divided into two groups:non-replacement treatment group (recievied intrastriatal application of QA alone) and replacement treatment group (received both QA and 17-? estradiol). Striatal neurons injury was evaluated using NADPH-diaphorase histochemistry and the rotation number of rats induced by apomorphine was recorded. Activity of SOD and contents of MDA in striatum was measured by xanthine oxidase and thio-barbital method, respectively.Results Compared with non-replacement treatment group, there was a significant increase in the number of NADPH-diaphorase positive neurons ( P

Clinical data of 12 patients with pernicious placenta previa admitted in our hospital from October 2015 to July 2016 were retrospectively reviewed.Bilateral internal ilia artery balloons were placed percutaneously before cesarean section.After cesarean delivery normal saline was applied to fill the balloon for temporary occlusion of bilateral iliac arteries,then placental separation and hysterorrhaphy were performed.The average volume of bleeding during cesarean section was 1 146 ml.There were no hysterectomy,pelvic organ necrosis,lower limb artery thromosis and other complications.The application of temporary internal iliac artery balloon occlusion can significantly reduce the intraoperative bleeding in cesarean section for patients with pernicious placenta previa.It provides a clear operational field for obstetricians to perform the placental separation and hysterorrhaphy,facilitating the uterine reservation.

Insulin resistance and its compensatory hyperinsulinemia play a key pathogenic role in the infertility of the polycystic ovary syndrome.Numerous studies indicate that insulin sensitizing drugs can be used to enhance spontaneous ovulation and the induction ovulation in the syndrome,The aim of this review is to summarize the studies in which insulin sensitizing drugs were used to increase ovulation rate or improve fertility in women with the PCOS and to translate the information into practical guidelines for reproductive endocrinologist.

This study was aimed to explore the methodology regarding culture, proliferation and purification of adipose-derived stromal cells (ADSCs), and to study their biological characteristics. ADSCs were obtained using type I collagenase digestion method. Cell growth was observed, and cell viability were detected under different digestion period by MTT. The ADSCs were then identified and induced. The results showed that adherent cells digested by type I collagenase for 60 min had a strong proliferation capability. After the induction of different inducers these adherent cells could differentiate into nerve cells and fat cells. The best digestion period was proved to be of 60 minutes in the experiment. The results indicate that stem cells with multilineage differentiation ability could be separated from adipose tissue, namely ADSCs.

Objective To study the relationship between extracranial carotid arerial stenosis and OCSP typing of acute cerebral infarction. Methods 188 patients with acute cerebral infarction were classified into TACI, PACI, POCI and LACI subtype by OCSP criteria. The lumen diameter, intima-media thickness, plaque, severity of ar-terystenosis of extraeranial carotid arteries in patients with acute cerebral infarction was studied by using HDI-5000 color Doppler ultrasound. Resnlts The prevalence of extracranial carotid arterial stenosis was higher in patients with TACI, POCI subtype than in patients with LACI subtype (X2 = 4.87, P < 0.05 ; X2 = 4.58, P < 0.05). The severity of extracranial carotid arterial stenosis were more prominent in patients with TACI,POCI subtype than in patients with LACI subtype(X2 =7.59,P <0.01 ;X2 =6. 96,P <0.01). Conclusion Extraeranial carotid arterial stenosis and its severity are related to TACI, POCI subtype of OCSP criteria in patients with acute cerebral infarction.

Objective To observe the efficacy of melbine combined with clomifene citrate in treatment of patients with polycystic ovarian syndrome ( PCOS) .Methods 60 patients aged 20 to 39 with PCOS were randomly divided into observation group and control group, 30 patients in each group.In the menstrual cycle of 3~7 d, the control group received clomifene citrate orally (50 mg per time, qd), and the observation group received melbine (2.5 mg per time, qd)combined with clomifene citrate (50 mg per time, qd), with a course of 5 days.Results The number of mature follicles and score of cervical mucus in obsercation group was significant higher than that in control group, respectively(P<0.05).The rate of follicular development and ovulation rate of single follicle in obsercation group was significant higher than that in control group, respectively(P<0.05), but there were no significant differences of pregnancy rate, first trimester abortion rate and periodic ovulation rate between two groups.The rate of endometrial thickness<7 mm patients in observation group was significantly lower and positive rate of three line was higher than that in control group, respectively ( P<0.05).The follicle stimulating hormone level in observation group was significantly lower than that in control group(P<0.05), but there was no significant difference of luteinizing hormone between two groups.Conclusion Melbine combined with clomifene citrate has a good effect on mature follicles number and endometrial thickness in anovulatory infertility women caused by polycystic ovary syndrome.

Objective To investigate the effect of different dose of GM1 on inducing human adipose tissue-derived stromal cells (ADSCs) into neural cells. Methods Human ADSCs were isolated from human liposuction tissues and cultured in NIM with different dose of GM1, which was used to induce ADSCs into neural cells. The experiment was separated into six groups: control group (?-MEM), Group A (NIM), group B (NIM+50 ?mol/L GM1), group C (NIM+100 ?mol/L GM1), group D (NIM+200 ?mol/L GM1) and group E (NIM+400 ?mol/L GM1). Cells' growth and morphologic changes were observed under invert phase-contrast microscopy. The expressions of Nestin, NSE, MAP2 and GFAP were identified by immunocytochemistry methods.Results (1)ADSCs could differentiate into neural cells in NIM with different dose of GM1. The number of neural cells differentiated from ADSCs increased in a certain period, especially in group E at each time point (all P
