Objective To explore the influence of preoperative chemotherapy (POCT) on telomerase activity(TA) of breast cancer and its mechanism. Methods TA was detected in 40 primary breast cancer specimens. Forty patients were divided into two groups: (1)POCT group. 32 patients, who underwent POCT using CMF scheme; (2) control group . 8 patients, who did not receive any POCT or radiotherapy. Results TA in POCT group(TA=0.499) was significantly lower than that in control group (TA=1.018). TA in patients received one , two or three times of POCT was 0.812,0.492 and 0.280 respectively. The difference of TA in patients received 1 time POCT and receive ≥ 2 times POCT was significant (P

AIM:As a factor that can improve cell growth,there are few studies about the effect of insulin-like growth factor Ⅰ(IGF-Ⅰ) on the apoptosis of endothelial cell.The study investigated the inhibition and mechanism of IGF-Ⅰ on the apoptosis of human umbilical vein endothelial cells(HUVEC) induced by oxidized low density lipoprotein(ox-LDL).METHODS:The experiment was performed in the Institute of Cardiovascular Disease,Union Hospital of Huazhong University of Science and Technology from December 2006 to July 2007.①Fresh human umbilical cord was obtained(the informed consent) to isolate and culture HUVECs.The cells were divided into four groups.Except the control group,HUVEC cells were cultured with IGF-Ⅰ(1?10-9mmol/L),ox-LDL(200 mg/L)+IGF-Ⅰ(1?10-9mmol/L),and ox-LDL(200 mg/L),respectively after cultured for 24 hours.②Cell viability was determined by MTT assay,morphology and apoptosis by DAPI fluorescence staining,and expressions of caspase-3 were analyzed.RESULTS:①Ox-LDL could significantly inhibit HUVEC cell proliferation.After treated with both IGF-Ⅰand ox-LDL,the cell proliferation increased obviously compared with the cells treated with ox-LDL(P

Objective : To evaluate the excess mortality risk related to heat wave in Ningbo, Zhejiang from 2013 to 2018, so as to provide a basis for formulating coping strategies for heat wave. Methods : The data of daily mortality, meteorological and air quality from May to October in Ningbo from 2013 to 2018 were obtained from Ningbo Center for Disease Control and Prevention, Ningbo Meteorological Bureau and Environmental Monitoring Center of Ningbo, respectively. The generalized linear model ( GLM ) and distributed lag non-linear model ( DLNM ) were used to estimate the associations between heat wave and cause-specific mortality. Results : Among 1 104 days of the study period, 18 heat waves occured and lasted for 132 days, accounting for 11.96%. A total of 102 954 deaths were reported in the same period. The risks of mortality in circulatory system diseases ( RR=1.09, 95%CI: 1.03-1.16 ), respiratory system diseases ( RR=1.14, 95%CI: 1.04-1.25 ), digestive system diseases ( RR=1.38, 95%CI: 1.15-1.65 ), nervous system diseases ( RR=1.32, 95%CI: 1.08-1.61 ), mental disorders ( RR=1.51, 95%CI: 1.12-2.03 ) and accidental injury ( RR=1.18, 95%CI: 1.06-1.32 ) and all causes ( RR=1.10, 95%CI: 1.06-1.14 ) increased at lag 0-1 day of heat wave. The total excess death related to heat wave was 1 218 ( 95%CI: 731-1 705 ) . The excess deaths of circulatory system diseases, respiratory system diseases, accidental injury, digestive system diseases, nervous system diseases, mental disorders, urinary system diseases and endocrine system diseases were 313 ( 95%CI: 104-556 ), 206 ( 95%CI: 59-368 ), 164 ( 95%CI: 55-292 ), 122 ( 95%CI: 48-208 ), 69 ( 95%CI: 17-131 ), 56 ( 95%CI: 13-113 ), 18 ( 95%CI: -15-64 ) and 3 ( 95%CI: -51-72 ). The excess deaths of urinary system and endocrine system diseases was not statistically significant ( P>0.05 ). Conclusion Heat wave can increase the mortality risk on the day and after a day in Ningbo from 2013 to 2018. Circulatory system diseases, respiratory system diseases and accidental injury rank top three in excess deaths.

Objective: To identify the most appropriate meteorological variable for forecasting the health risk of high temperatures. Methods: The surveillance on causes of death, meteorological data and surveillance on air quality among registered residents in Ningbo City, Zhejiang Province during the period between May and October from 2013 to 2019 were collected. The association models of daily minimum temperature, average daily temperature, daily maximum temperature, daily minimum heat index, average daily heat index, daily maximum heat index, average daily apparent temperature and torridity index with deaths and years of life lost (YLL) were created using time series analysis and distributed lag non-linear models, and the model fitting effect was evaluated using the minimum Akaike information criterion (AIC) procedure. The most appropriate meteorological variable for forecasting gender-, age- and mortality-specific health risks of high temperatures was identified. Results: A total of 120 628 deaths were reported during the study period, with daily deaths of 94 cases, and daily YLL rate of 19.74 person-years/105. Except for daily minimum heat index and torridity index, the exposure-response relationships between other six meteorological variables and deaths and overall YLL rate all appeared a “J” shape. The lowest AIC values and the optimal model fitting effects were measured for the association models between average daily temperature and whole populations, females, subjects at ages of 65 years and older, and deaths and YLL rates due to circulatory diseases and respiratory diseases. Conclusion High model fitting effects are observed between average daily temperature and deaths and YLL rates, which are more suitable for forecasting the health risk of high temperature.

Objective To compare the differences between the cell swelling of cultured astrocytes ( AST) from Wistar and Sprague-Dawley ( SD) rats after incubation with glutamate.Methods Primary cultured AST derived from the cerebral cortex of one-day-old Wistar or SD rats were prepared.The cultured AST received 1 or 10 mmol/L glutamate treat-ment for 48 h on the tenth day after subculture.The viability of AST was determined by lactate dehydrogenase ( LDH) kit to assess the cell injury, and the perimeter of AST was measured using Image Pro Plus software after glial fibrillary acidic protein immunofluorescence staining to evaluate the astrocyte swelling.Then, the expression of aquaporin 4 ( AQP4 ) in cultured AST was detected by quantitative reverse transcription polymerase chain reaction.Results No significant differ-ence was found in the LDH release after the glutamate treatment in cultured AST from these two strains (P>0.05).The perimeter of AST from normal Wistar rats was shorter than that from SD rats, but was longer after the treatment of glutamate (P<0.05).Meanwhile, AQP4 expression in the Wistar rats was significantly higher than that from SD rats after incuba-tion with 1 mmol/L glutamate ( P<0.05 ) .Conclusions These results suggeste that cultured AST from Wistar rats are more susceptible to glutamate-induced swelling than that from SD rats, and there are differences between the effects of glu-tamate on AQP4 expression in astrocytes of Wistar and SD rats.

Objective To investigate safety and efficiency of anti-coagulation therapy in patients with high-risk of bleeding and multiple organ dysfunction syndrome (MODS) during continuous veno-venous hemofiltration (CVVH). Meth-ods Forty patients with high-risk bleeding MODS during CVVH in our hospital were divided into heparin-free group (A group) and low-dose heparin group (B group). Blood coagulation function, platelets counts, blood urea nitrogen, serum creati-nine, PaO2/FIO2 and Apache Ⅱ scores in two groups were tracked before treatment and 24 h, 48 h after treatment. Filter lifespan, median ventilation time, ICU admission time and bleeding complications were observed. Results (1)There was significant difference in levels of blood urea nitrogen, serum creatinine, PaO2/FIO2 and ApacheⅡscores at 24 h, 48 h after treatment between in low-dose heparin group and those in heparin-free group (P＜0.05). (2)Levels of activated partial thromboplastin time(APTT), thrombin time (TT) were prolonged. Platelets count were significantly lower at 24 h after treat-ment than that before treatment in low-dose heparin group. Levels of APTT, TT and platelets count had no changes with pro-longed time of CVVH therapy.(3)Average ventilation time, ICU admission time were obviously shorter in low-dose heparin group than that in heparin-free group. Filter lifespan was significant longer in low-dose heparin group than that in heparin-free group, (P＜0.05).(4)Bleeding in skin and mucosa was observed in 1 case in low-dose heparin group without other se-vere bleeding complications. Conclusion The results of monocentric study show that low dose of heparin ensure smooth op-eration of CVVH in patients with MODS and high-risk bleeding. The clinical application is safe and efficient.
