Objective To investigate the effect of Notch1 and Jagged1 on the growth of prostate cancer PC3 cells and the regulation of Jagged1 expression by its receptor Notch1 in PC3. Methods Notch1 and Jagged1 expression were inhibited by siRNA interference. The growth rate of PC3 cells was measured by MTT. Notch1 expression was inhibited by siRNA interference and promoted by transfection of Notch1 cDNA. The changes of Notch1 and Jagged1 protein and mRNA levels were measured by Western blot and Real-time RCR. Results The growth of PC3 cells decreased after inhibiting Notch1 and Jagged1 expression. Jagged1 protein level decreased after inhibiting Notch1 expression and increased after over-expressing Notch1. Moreover, the change of Jagged1 protein level was discordant with the situation of mRNA. Conclusion In PC3 cells, Notch1 and Jagged1 are important to cell growth. Notch1 may regulate Jagged1 expression.

Objective To compare the effect of GammaTM wet wipes and 75% alcohol on the disinfection of X-ray protective clothing,and provide reference for choosing rational disinfection methods.Methods 62 pieces of X-ray protective clothing were selected,30 were from operating rooms,32 from catheterization room.Protective clothing were randomly divided into trial group and control group,each had 31 pieces.Trial group disinfected clothing with GammaTM wet wipes,control group disinfected clothing with 75% alcohol,disinfection effect,drying time,and cost between both groups were compared.Results Average bacterial colony counts in trial group and control group before disinfection were 2.38 CFU/cm2 and 2.36 CFU/cm2 respectively,qualified rates were 80.64% and 83.87%respectively.Bacteria were not detected in both groups after disinfection.The average drying time in trial group was shorter than control group([352.35±9.93]s vs[676.13±10.62]s,t=123.98,P <0.01).The cost of disinfecting X-ray protective clothing in trial group was 29.60% less than control group.Conclusion Effect of GammaTM wet wipes and 75% alcohol on disinfecting X-ray protective clothing are both reliable,compared with 75% alcohol, GammaTM wet wipes are without corrosion,have shorter drying time,and save more cost.

Objective To study the degradation of hepatitis C virus(HCV) genome before and after methylene blue photochemistry(MB-P) treatment of the plasma.Methods MB was added to HCV positive plasma to a final concentration of 1.0?mol/L.The plasma was then exposed to 30000 Lux fluorescence.Plasma samples were then collected at different times of exposure.Real-time PCR was used to quantitatively study the course of the HCV-RNA degradation.The whole genome was screened for integrity by RT-PCR with 8 pairs of specific primers which targeted sequential overlapping sections of HCV genome.Results Results of real-time PCR showed that the copy number of HCV-RNA was continuously decreasing during MB-P treatment.RT-PCR results showed that the reactivity of different sections of the HCV genome to MB-P was significantly different and indicated that the 5' end and 3' end were more stable. Conclusion MB-P treatment could degrade HCV RNA with various sensitivities to different sections of the genome.RNA degradation may play an important role in plasma virus inactivation.Detection of HCV genomic RNA might be clinically useful to monitor the process and efficiency of virus inactivation.

There are some problems in the teaching of medical physics course,such as low learning initiative,deficient grasp of concept,and obstacles to realize the internalization and practical application of knowledge.The PAD (presentation-assimilation-discussion) class is applied in the course,in order to improve the students' learning state.PAD class is a teaching mode proposed from a psychological point,which advocates that teaching is the first before students start to learn and has an equal treatment on students' discussions and teachers' instruction,supporting independent learning.The teaching measures include:selecting course content to reach the balance between simplification and detailed interpretation;assigning open homework based on the course;dividing the class discussion into four steps;assessing students based on the performances of homework and final examinations.The research has shown that the PAD class facilitates improving the students' initiative of study and promoting the absorption and application of knowledge.

Objective To observe the therapeutic efficacy of needling QIN's eight head acupoints in treating insomnia.Method Sixty patients were randomized into QIN's eight head acupoints group (30 cases) and a conventional acupuncture group (30 cases). The modified Spiegel sleep questionnaire was evaluated respectively after 4-week and 8-week treatment.Result After 4-week treatment, there was a significant difference in comparing the modified Spiegel sleep questionnaire between the two groups (P<0.05), and QIN's eight head acupoints group was superior to the conventional acupuncture group; after 8-week treatment, there was no significant difference between the two groups in comparing the modified Spiegel sleep questionnaire (P>0.05).Conclusion QIN's eight head acupoints group had a more significant therapeutic efficacy compared to conventional acupuncture group after 4-week treatment.

Aim To investigate the effect of the extract of Averrhoacarambola L.root (EACR)on renal func-tion in diabetic mice and its anti-oxidative action. Methods Diabetic mice were established by tail vein injection with 120 mg·kg-1 streptozotocin (STZ)and were divided into 5 groups:model control group,val-sartan control group,and low-,middle-,high-dose of EACR groups (300,600,1 200 mg·kg-1 ).And 10 normal mice consisted of normal control group.The fasting blood glucose (FBG)of mice was detected be-fore and after administration of drugs.After last admin-istration,the blood and urine samples were collected for creatinine (Cr),urea nitrogen (BUN),urine and 24 h urinary protein determination.The activities of superoxide dismutase (SOD ),glutathione peroxidase (GSH-Px)and malonaldehyde (MDA)content were determined using kits.HE staining was conducted to observe the pathological changes of kidney tissues. ELISA method was utilized to detect the contents of catalase (CAT)and reactive oxygen species (ROS ). The expressions of Cyto-C,AIF and caspase-3 proteins in kidney tissues were analyzed by Western blot.Re-sults Compared with model group,the serum bio-chemical indexes and 24 h urinary protein of valsartan and moderate-,high-dose of EACR groups were de-creased with statistical significance (P<0.05 ).After the treatment, the MDA content was decreased by EACR treatment,and SOD,GSH-Px and CAT activities were enhanced.Meanwhile the expressions of ROS, Cyto-C,AIF and caspase-3 were down-regulated.The pathological changes of kidney tissues were ameliorated by EACR through HE results.Conclusions The ex-tract of Averrhoacarambola L.root can decrease the se-rum levels of Cr and BUN,reduce the MDA and ROS contents in kidney tissue and enhance the activities of SOD,GSH-Px and CAT,down-regulate the expres-sions of Cyto-C,AIF and caspase-3 proteins in kidney tissues,elevate the anti-oxidative effect of kidney. Therefore,the renal function of diabetic mice is melio-rated.
