Aim This study was designed to investigate the inhibition of matrine on U251 glioma cell line and its mechanism. Methods MTT was used to measure the levels of the proliferation of U251 cultured with matrine in different concentrations.The effects of matrine on cell cycle of U251 were observed by FCM. The expression of proto oncogenes c myc was measured by RT PCR. Results The proliferation of U251 was obviously inhibited by matrine in a dose dependent manner. The inhibitory rate was (53 7?6 0)%,when cultured with matrine at 0 10 g?L -1 . The outcome of FCM showed that the proportion of G 0/G 1 phase cells were decreased. The proportion of S phase cells were reduced obviously,when cultured with matrine at 0 10 g?L -1 in 3 days.The outcome of RT PCR showed that the expression of proto onco gene C myc was notably decreased, when the dose of matrine was increased. Conclusion Matrine can inhibit the proliferation of U251 and inhibit the expression of proto onco gene C myc.

Objective:
To understand the behavioral characteristics of vaccination of human papillomavirus (HPV) vaccine based on diffusion of innovation theory, and to put forward suggestions for improving the vaccination willingness.
Methods:
The women who had made an appointment or received at least one dose of HPV vaccine in two community health service centers with HPV vaccination qualification in Hangzhou were recruited by convenience sampling method. A questionnaire survey was conducted according to cervical cancer risk factors, HPV vaccine knowledge and the time of vaccination. The diffusion of HPV vaccination and the characteristics of vaccinees in different stages was analyzed.
Results:
A total of 448 women, aged from 18 to 45 years old, with a median of 30.5 years old, were investigated. The spread of HPV vaccine were divided into five stages: April 2017 and before was the initial stage, with 8 leaders, accounting for 1.79%; October 2017 to February 2018 was the slowly rising stage, with 59 early vaccinees, accounting for 13.17%; April 2018 to April 2019 was the rising stage, with 160 most early vaccinees, accounting for 35.71%; May to August 2019 was the rapidly rising stage, with 170 most late vaccinees, accounting for 37.95%; September 2019 to the end of the survey was the standstill stage, with 51 laggards, accounting for 11.38%. All of the leaders had participated in cervical cancer screening, voluntarily vaccinated, and knew the susceptible population of cervical cancer, the targeted HPV types and the suitable population of vaccine. The median age of the first pregnancy was 27 years old. Six of them had three pregnancies. The early vaccinees and the most early vaccinees were recommended by doctors or friends to get HPV vaccine. The median age of first pregnancy was 26 and 28 years old, respectively. Their other characteristics were similar to those of the leaders. The characteristics of most late vaccinees were similar to those of the laggards. They were were mainly students who were recommended by their friends to receive HPV vaccination, did not participate in cervical cancer screening, did not know the susceptible population of cervical cancer, the targeted HPV types and the suitable population of vaccine.
Conclusions
People with high risk of HPV exposure, awareness of cervical cancer and screening are more likely to receive HPV vaccination at the early stage. It is necessary to strengthen the health education of HPV vaccination, and make full use of the influence of doctors and early vaccinees, which is helpful to promote the early vaccination of HPV vaccine among the right age population.

Objective To investigate the levels of serum soluble CDI4(sCD14)in patients early after renal transplantation and the relationship between sCD14 and allograft rejection.Methods This se- ries included 51 consecutive patients undergoing renal transplantation.We prospectively determined levels of serum sCD14 at 1 h before transplantation(d 0)and the first 10 d after transplantation(d 1-10).The ser- um creatinine(Cr)levels were recorded at the same time.The patients were divided into 2 groups(rejection and non-rejection groups)according to whether they experienced acute rejection or not during the first 14 d after transplantation.The levels of serum sCD14 and Cr between the 2 groups were compared.Results Of 51 cases,13 experienced acute rejection,and the mean time from postoperation to rejection start was 7 d;38 cases had no rejection.On d 0,the Cr levels of rejection group[(789?221)?mol/L]and non-rejection group[(742?234)?mol/L]had no significant difference(P>0.05).The Cr level was higher in rejection group than in non-rejection group on d 1-10.In the 2 groups,the Cr levels of d 3 and d 5 to d 10 were (237?104)vs(160?70),(176?85)vs(117?46),(174?81)vs(112?40),(173?81)vs(112?39),(209?53)vs(112?38),(203?73)vs(103?35),(181?50)vs(102?31)?mol/L,respective- ly,with significant difference between them(P<0.05).The serum sCD14 levels on d 0 in rejection group [(9.55?5.71)mg/L]and non-rejection group[(8.99?3.89)mg/L]had no significant difference.The sCD14 levels were higher in rejection group than in non-rejection group on d 1-5[(15.52?6.60)vs (9.85?4.11),(15.48?5.85)vs(7.53?3.79),(12.15?4.45)vs(5.88?3.95),(10.84?4.11) vs(4.88?3.17),(7.61?5.37)vs(4.66?1.91)mg/L,respectively]with significant difference(P<0.05).The sCD14 levels in the 2 groups on d 1 were elevated compared with those on d 0,then decreased gradually.Conclusions It is suggest that the increase in serum sCD14 levels occurs earlier than clinically acute rejection.The serum sCD14 levels on d 1-5 after transplantation can serve as important predictors for acute renal graft rejection.
