OBJECTIVETo investigate the role of mitogen-activated protein kinases (MAPKs)-extracellular signal regulated kinase1/2 (ERK1/2) signal pathway in the regulation of Compound Danshen Injection (CDI) induced AQP3 expression in the human amniotic epithelial cells (hAECs).

METHODShAECs of term pregnancy with normal amniotic fluid volume (AFV) or isolated oligohydramnios were primarily cultured. And the cells were equally divided into four groups, i.e., the vehicle control group, the U0126 group, the CDI group, the CDI + U0126 group. The expressions of phosphorylated ERK1/2 (p-ERK1/2) and AQP3 in hAECs were detected using Western blot analysis.

RESULTS(1) When compared with the control group, the expression level of p-ERK1/2 in hAECs in those with normal AFV and oligohydramnios obviously decreased in the U0126 group (P < 0.05). The expression level of p-ERK1/2 could be elevated in the CDI group (P < 0.05). The expression level of p-ERK1/2 in hAECs was higher in the CDI +U0126 group than in the U0126 group, but lower in the CDI + U0126 group than in the CDI group (P < 0.05). (2) There was no obvious change in AQP3 expression in hAECs with normal AFV between the U0126 group and the vehicle control group (P > 0.05). There was no statistical difference in the expression level of AQP3 between the CDI group and the U0126 +CDI group (P > 0.05), but they were higher than those in the vehicle control group (P < 0.05). (3) Compared with the vehicle control group, the expression level of AQP3 in hAECs with oligohydramnios significantly decreased in the U0126 group and increased in the CDI group (P < 0.05). The expression level of AQP3 was lower in the U0126 + CDI group than in the CDI group, but higher in the U0126 +CDI group than in the U0126 group (P < 0.05).

CONCLUSIONCDI could regulate AQP3 expression level in hAECs with oligohydramnios via activating the MAPK-ERK1/2 signal transduction pathway.

Objective To investigate the radioprotective effect of cimetidine on survival rate and hematopoietic system in acutely irradiated mice.Methods The total body irradiation doses were 6.0Gy and 8.0Gy respectively at 1.01Gy/min rate. Sixty healthy male C57BL/6 mice were randomly divided into control group, model group, positive-drug (523) group and cimetidine groups (33.3mg/kg, 100mg/kg and 300mg/kg). Each group had ten mice. The mice were given intragastric administration of cimetidine for 6d before the irradiation in cimetidine groups, and 523 was administered before irradiation once a day for one day in 523 group, and at 5h after irradiation, was given again. The 30d survival rate after 8.0Gy irradiation was recorded. The peripheral blood cells, bone marrow DNA content and frequency of micronucleated polychromatic erythrocytes (fMNPCE) were determined 30d after 6.0Gy irradiation.Results After 8.0Gy irradiation, all the mice died on 21th day in model control group. The survival rates in cimetidine groups were 50%, 20% and 30%, respectively. After 6.0Gy irradiation on 30th day, compared with control group, the peripheral white blood cells (WBC) and bone marrow DNA content were decreased significantly (P<0.01,P<0.05) in model group, and fMNPCE was increased significantly (P<0.05). Compared with model group, WBC was significantly increased in 300mg/kg cimetidine group (P<0.01). In cimetidine groups, the bone marrow DNA content was increased significantly after irradiation (P<0.01 orP<0.05), and the fMNPCE was decreased significantly (P<0.01 orP<0.05) and tended towards normal.Conclusion Cimetidine could improve 30d survival rate of acutely irradiated mice and has good protective effect on hematopoietic system.

Objective To investigate the characteristics of methadone maintenance treatment(MMT)clients, and to explore their retention rate and associated factors in Taizhou, Zhejiang Province. Methods Heroin or opiate addicts who started MMT between 2006 and 2014 in study area were included. Data including demographics, history of drug use and treatment information was extracted from the National MMT Data Management System and descriptive analysis were conducted. Multiple logistic regression models were used to explore factors associated with retention rate. Results In total, 2 262 MMT clients were included for analysis. Most of them were male(87.53%), single, divorced or widowed(55.75%), and had an education of junior middle school or below(88.68%). Almost all of them (98.32%)were heroin addicts, and the age at first drug use ranged from 9 years to 54 years, with average age of(25.06±6.34)years. A total of 1 123(49.65%)clients had a history of inject drug use and 81(3.58%)clients had ever shared needles with others. The average duration on MMT was 5.02±2.01 years, and the average methadone dosage during treatment was (34.49 ±22.69)mL. The MMT retention rate was 29.2% (661/2 262). In multivariable analysis, districts such as Huangyan District, Yuhuan County and Linhai City, aged≥40 years and average methadone dosage>20 mL during treatment were independently and positively associated with retention rate. Conclusion Most of MMT clients in Taizhou are male, unmarried, and had low education level. The retention rate is low in Taizhou but older patents and those receive high methadone dosage have a relatively higher retention rate.

The reliability and validity of risk assessment scale (RAS) of pressure sore during 3S surgery were investigated. RAS of pressure sore was designed independently during 3S surgery. Five operating room nursing experts were selected to consult and detect face validity. Convenient and purposive sampling of 707 samples was conducted. Cronbach's alpha was used to measure content reliability and evaluate the internal consistence of RAS. The structural reliability was investigated by exploratory factor analysis method. The results showed that the content validity index was 0.92, and Cronbach's alpha of content reliability was 0.71. Structural validity, detected by Bartlett sphericity test, was 135.3 for 707 samples with the difference being statistically significant (P<0.01). KMO value was 0.729. The accumulative variance contribution ratio of common factor was 64.63%. The exploratory factor analysis showed the factor load of every clause was larger than 0.596. It was concluded that RAS of pressure sore for 3S surgery has better validity and reliability, and it could be used for evaluating and screening the high risk patients with pressure sores during surgery in order to efficiently reduce the occurrence of pressure sore during surgery. RAS of pressure sore for 3S surgery is worth to be popularized.
