Correlation between sleep quality and brachial-ankle pulse wave velocity of physical examination people / 中国医师杂志

Objective To investigate the sleep quality state of people who did physical examination,and its correlation with brachial-ankle Pulse Wave Velocity (baPWV).Methods The indexes of Pittsburgh sleep quality index (PSQI) and baPWV were used.The people who did physical examination were divided into sleep disorders group (284 cases) and normal sleep group (608 cases) according to the results of PSQI survey.Results (1) There were 31.84％ of the people who had sleep quality problems.(2) The PSQI total score and the score of subjective sleep quality (SSQ),sleep duration (Sdu),daytime dysfunction (DD) of females were higher than males (t =6.71,3.46,2.45,3.96,P ＜0.05).The PSQI total score and the score of sleep latency (SL),habitual sleep efficiency (HSE),use of sleeping medication (USM) among different age groups were statistically analyzed (F =12.23,8.31,7.50,7.11,P ＜ 0.05).(3) The score of baPWV of sleep disorders group was higher than normal sleep group (t =5.14,P ＜ 0.05).There were significantly positive correlation between baPWV and total PSQI score,subjective sleep quality,sleep time,daytime dysfunction (r =0.28,0.45,0.30,0.36,0.35,P ＜ 0.05).Conclusions 1/3 of the physical examination people have sleep quality problems.Sleep quality of females is worse than males.There are different styles among different age groups.There is significantly positive correlation between sleep quality and baPWV.

Microsphere Preparation of The Recombinant Adeno-Associated Virus as A Vector for Gene Therapy of Liver Cancer / 中国普外基础与临床杂志

Objective To evaluate the suitability of the biodegradable microsphere encapsulation of adenovirus as a targeting vector for gene therapy of hepatocellular carcinoma. Methods Encapsulate the recombinant adenovirus in PLG poly (lactic/glycolic) copolymer by the solution evaporation method, the release test and the bioactivity of viruses incorporated in vitro were studied. Results More than 19.3% of adenovirus was encapsulated in PLG microspheres. The release test shows that the adenovirus was released for more than 200 h, 50% were shed within the first 100 h, and their activity was retained. Conclusion Recombinant adenovirus can be formulated in a polymer preparation of PLG with retention of bioactivity. It may be a valuable vector for the gene therapy of liver cancer.
