OBJECTIVETo study the anti-tumor activity of SPS in vivo and in vitro and the cytotoxicity of CTL cells, NK cells of T739 lung cancer in mice.
METHODThe transplanted tumor model of S180 Sarcoma was established with KM mouse. The SPS was adminished i.p. for 10 d, the tumor weight was detected. The transplanted tumor model of LA795 lung cancer was established with T739 mouse and SPS was adminished i.p. for 10 d and the tumor weight and the cytotoxicity of CTL cells, NK cells were detected. The Anti-tumor activity of SPS on three types of tumor cells in vitro was observed with trypan blue exclusion staining.
RESULTSPS 40 mg x kg(-1) can significantly inhibit the growth of S180 Sarcoma in mice and inhibitory rate was 51.33% (P<0.01). It can also inhibit the growth of LA795 lung cancer in mice and the tumor volume was reduced obviously for 3.29 mm3 (P<0.05). It can remarkably enhance the cytotoxicity of splenic CTL cells, NK cells in tumor-bearing (P<0.05).
CONCLUSIONSPS have anti-tumor effects, the mechanism of the anti-tumor activity may be related to enhance the cytotoxicity of CTL cell and NK cell.

OBJECTIVE:
To investigate the effect of working time on the prognosis of patients with ischemic stroke undergoing intravenous thrombolysis.
METHODS:
Clinical data of 3050 patients with ischemic stroke received intravenous thrombolysis from 71 hospitals in Zhejiang Province during June 2017 and September 2018 were retrospective analyzed. Whole day of Saturday and Sunday were defined as weekend; whole day of Monday to Friday were defined as weekdays; Monday to Friday 8:00-17:00 were defined as daytime of weekdays; Monday to Friday 17:01-07:59 on next day were defined as nights of weekdays; unconventional working time were defined as weekend and nights of weekdays. Good outcome was defined as mRS 0-2 at 3 months. Univariate analyses of baseline and prognostic variables in group of weekend and weekdays, nights of weekdays and daytime of weekdays, unconventional working time and daytime of weekdays were performed. Binary logistic regression was used to investigate whether weekend, nights of weekdays and unconventional working time were independent predicting factors of outcome after intravenous thrombolysis, respectively.
RESULTS:
There was no difference in 7-day mortality, 3-month mortality and good outcome at 3-month between weekend group and weekdays group, nights of weekdays group and daytime of weekdays group, unconventional working time group and daytime of weekdays group (all >0.05). Binary logistic regression results showed that weekends, nights of weekdays and unconventional working time were not independent predicting factors for outcome after intravenous thrombolysis (all >0.05).
CONCLUSIONS
The working time has not affected the outcomes of patients with ischemic stroke undergoing intravenous thrombolysis in studied hospitals of Zhejiang province.

OBJECTIVE:
To compare the time delay between in-hospital stroke and out-of-hospital stroke patients, and to explore the influence factors for the prognosis of in-hospital stroke patients treated by intravenous thrombolysis.
METHODS:
Clinical data of 3050 patients with ischemic stroke who received intravenous thrombolysis in 71 hospitals in Zhejiang province from June 2017 to September 2018 were analyzed. Differences of time delay including door to imaging time (DIT), imaging to needle time (INT) and door to needle time (DNT) between in-hospital stroke (=101) and out-of-hospital stroke (=2949) were observed. The influencing factors for the outcome at 3 month after intravenous thrombolysis in patients with in-hospital stroke were analyzed using binary logistic regression analysis.
RESULTS:
Patients with in-hospital stroke had longer DIT[53.5 (32.0-79.8) min vs. 20.0 (14.0-28.0) min, <0.01], longer IDT[47.5(27.3-64.0)min vs. 36.0(24.0-53.0)min, <0.01], and longer DNT[99.0 (70.5-140.5) min vs. 55.0 (41.0-74.0) min, <0.01], compared with patients with out-of-hospital stroke; patients in comprehensive stroke center had longer DIT[59.5(44.5-83.3) min vs. 37.5(16.5-63.5) min, <0.01], longer DNT[110.0(77.0-145.0) min vs. 88.0 (53.8-124.3) min, <0.05], but shorter INT[36.5(23.8-60.3)min vs. 53.5 (34.3-64.8) min, <0.05], compared with patients in primary stroke center. Age (=0.934, 95% 0.882-0.989, <0.05) and baseline National Institute of Health Stroke Scale score (=0.912, 95% 0.855-0.973, <0.01) were independent risk factors for prognosis of in-hospital stroke patients.
CONCLUSIONS
In-hospital stroke had longer DIT and DNT than out-of-hospital stroke, which suggests that a more smooth thrombolysis process of in-hospital stroke should be established.

OBJECTIVE:
To investigate the association of atrial fibrillation (AF) with hemorrhagic transformation (HT) in patients with ischemic stroke treated by intravenous thrombolysis.
METHODS:
Clinical data of 3272 patients treated by intravenous thrombolysis from 71 hospitals in Zhejiang Province during June 2017 and December 2018 were retrospectively reviewed. Intracranial HT was defined as intracranial hemorrhage suggested by imaging examination 24 hours after intravenous thrombolysis. Patients were dichotomized into HT group (=533) and non-HT group (=2739). The association of AF and HT was analyzed by univariate analysis and binary logistic regression.
RESULTS:
Compared with the non-HT group, the HT group were older, had longer onset to needle time (ONT), higher baseline National Institute of Health Stroke Scale (NIHSS) score, higher baseline glucose level, and higher AF rate (<0.05 or <0.01). Binary logistic regression analysis revealed that AF was independently associated with HT (=2.527, 95%:2.030-3.146, <0.01).
CONCLUSIONS
AF is independently associated with the occurrence of HT in ischemic stroke patients treated with intravenous thrombolysis.

OBJECTIVE:
To investigate the effect of treatment time on the outcome of patients with ischemic stroke undergoing reperfusion therapy.
METHODS:
The clinical data of 3229 ischemic stroke patients who received intravenous thrombolysis with or without arterial thrombolysis from 71 hospitals in Zhejiang province from June 2017 to September 2018 were retrospectively reviewed. The good outcome was defined as modified Rankin Scale (mRS) ≤ 2. Binary logistic regression analysis was used to investigate the association of door to needle time (DNT), or door to reperfusion time (DRT) with the outcomes in patients treated by intravenous thrombolysis or bridging arterial thrombolysis, respectively.
RESULTS:
Binary logistic regression showed that DNT (=0.994, 95%:0.991-0.997, <0.01) or DRT (=0.989, 95%:0.983-0.995, <0.01) were independently associated with good outcomes, respectively. Every hour decreases in DNT resulted in a 4.7%increased probability of functional independence (mRS 0-2) in patients treated by intravenous thrombolysis; Every hour decreases in DRT was associated with a 11.4%increased probability of functional independence in patients treated by intravenous thrombolysis with arterial thrombolysis.
CONCLUSIONS
Good outcomes are associated with lower DNT in ischemic stroke patients treated by intravenous thrombolysis or lower DRT in patients treated by intravenous thrombolysis bridging arterial thrombolysis.

OBJECTIVE:
To investigate the effect of emergency medical service (EMS) on the prognosis of ischemic stroke patients treated with intravenous thrombolysis.
METHODS:
Clinical data of 2123 ischemic stroke patients treated with intravenous thrombolysis in 70 hospitals in Zhejiang province were retrospectively analyzed. There were 808 patients sent to the hospital by ambulance (EMS group) and 1315 patients by other transportations (non-EMS group). Good outcome was defined as modified Rankin Scale (mRS) ≤ 2 at 3-month. The onset to needle time (ONT), onset to door time (ODT), door to needle time (DNT) and outcome were compared between EMS group and non-EMS group. Binary logistic regression was used to explore the influencing factors for the outcome at 3-month.
RESULTS:
Compared with the non-EMS group, patients in the EMS group were older, with higher baseline National Institute of Health Sroke Scale (NIHSS) score, and had a higher proportion of atrial fibrillation (all <0.05), but there were no significant differences in ONT, ODT and DNT between two groups (all >0.05). Binary logistic regression showed that EMS was not independently associated with good outcome (=0.856, 95%:0.664-1.103, >0.05).
CONCLUSIONS
EMS had not improve the outcome of patients receiving intravenous thrombolysis in Zhejiang province.

OBJECTIVETo evaluate the efficacy and metabolic safety of long-term treatment with ethinyl oestradiol/cyproteroneand desogestrel/ethinyl oestradiol tablets in women with polycystic ovary syndrome (PCOS).
METHODSWomen with PCOSfrom West China Second Hospital of Sichuan University enrolled between September, 2011 and August, 2013 were randomlyallocated to receive either ethinyl oestradiol/cyproterone tablets (Group A, =355) or desogestrel/ethinyl oestradiol tablets(Group B, =357) for a prospective observation period of 6 months. Women with insulin resistance also received metformin. Atbaseline, 3 months, and 6 months, the patients were evaluated for menstruation, acne score, body mass index (BMI), waist-tohip ratio (WHR), plasma levels of sex hormones, fasting blood glucose (FPG), HOMA-insulin resistance index (HOMA-IR), serum lipid, ovarian volume, and the number of ovarian follicles.
RESULTSAll the patients had a regular menstrual cycle aftertreatments. Testosterone level, acne score, LH/FSH, ovarian volume, and the number of follicles decreased significantly afterthe treatments without significant differences between the two groups. Significant increases were noted in TG, TCh, LDL, HDL, and AIP, and HDL level in group A as compared with group B ( < 0.001). FPG decreased in both groups, and wassignificantly lower in group B at 6 months ( < 0.05). BMI and WHR decreased in all the patients with insulin resistance aftercombination treatment with metformin ( < 0.05), but increased significantly in patients without insulin resistance ( < 0.05). Ingroup A, HOMA- IR significantly increased in patientswithout insulin resistance at 3 months ( < 0.05), whereas asignificant increase was not observed until 6 months ingroup B ( < 0.05).
CONCLUSIONSBoth ethinyl oestradiol/cyproterone tablets and desogestrel/ethinyl oestradioltablets can relieve the symptoms of PCOS, but it isadvisable to assess the risk of cardiovascular diseasebefore the treatments.
