1.Quality of life and its influencing factors in elderly patients with advanced cancer
Chinese Journal of General Practitioners 2017;16(2):118-121
Objective To assess the quality of life and its influencing factors in ellerly patients with advanced cancer.Methods The quality of life was evaluated with EORTC QLQ-C30 scale Chinese version in 103 elderly patients with advanced cancer in a hospital outpatient clinic of Beijing from July 2013 to July 2014.The overall health,physical function,role function,cognitive function,emotional function,social function and individual symptoms score were assessed.The general information and clinical data of patients were analyzed.Results The general score of quality of life in elderly advanced cancer patients was (35.77 ± 21.98).In the domain of function the role functional score was the lowest (36.60 ± 27.97);in the domain of symptoms the tired score was the highest(50.82 ± 30.16),the score of appetite loss was the highest in individual symptoms (39.78 ± 24.32).Educational level,marital status,living condition,medical insurance and the number of comorbidities were correlated with overall health in elderly patients with advanced cancer (P < 0.05).Multiple linear regression analysis showed that the educational level (t =2.447,P < 0.05),marital status (t =2.118,P < 0.05),medical insurance (t =3.770,P < 0.05) and overall health status were positively correlated with the quality of life scores;and number of eomorbidities (t =-7.157,P < 0.05) was negatively associated with the overall quality of life.Conclusion The quality of life was generally poor in elderly patients with advanced cancer;and educational level,marital status,medical insurance,comorbidities are important influencing factors.

Journal of Shanghai Jiaotong University(Medical Science) 2006;0(01):-
Objective To design a good scoring function for predicting the tertiary structures of proteins. Methods A scoring function,which was composed of simple sum of pairwise distance-dependent potentials of C?-C?,N-N,C′-C′ and backbone dihedral angle-dependent potentials,was proposed in this paper. Results The performance of the scoring function was verified with experiment to be improved. Conclusion The proposed scoring function is effective and valid in predicting the tertiary structures of proteins.

In the research field of quality control in Chinese medicinal materials, variation in active ingredients of medicinal plant is always the key and hot issues. With the development of high-throughput sequencing technologies and reducing cost, a large numbers of genes from medicinal plant were cloning and provide a solid foundation for further research of gene structure and its biological function, and also provides conditions for explore active ingredient variation and its quality control from the perspective of molecular pharmacognosy. This paper introduces the concept of homologous gene, gene duplication and classification. We prospect the function of duplicated genes in the role of molecular mechanism research about variation in active ingredients, aiming at providing a new way for medicinal materials quality control.

Survivin-D53A (SVV-D53A) is a dominant-negative mutant survivin, which represents a potential promising target for cancer gene therapy. The present study was designed to determine whether SVV-D53A plasmid encapsuled by DOTAP: Chol liposome would have the anti-tumor activity against SPC-A1 lung adenocarcinoma, and to detect the possible mechanisms. In our experiment, SPC-A1 cells were transfected in vitro with SVV-D53A plasmid and examined for protein expression by Western blot, then flow cytometric analysis was used to detect apoptosis. SPC-A1 lung adenocarcinoma xenografts were established in vivo in the nude mice, which received the i. v. administrations of SVV-D53A plasmid/liposome complexes. After mice were sacrificed, the paraffin-embedded tumor tissue sections were used for proliferating cell nuclear antigen (PCNA) expression and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. Compared with the control group, the mice treated with SVV-D53A plasmid had an obviously reduced tumor volume, with high level of apoptosis and decreased cell proliferation in tumor tissue. The research results proved that the administration of SVV-D53A plasmid resulted in significant inhibition of SPC-A1 cells both in vitro and in vivo. The functional mechanism is that the anti-tumor response causes and induces tumor cell apoptosis.

As an indispensable part of minority traditional medicine, mineral medicine has used with less dosage and reliable efficacy for the last thousand years. Based on the unearthed relics and medical literatures of past dynasties, the history of Han nationality ap- years, which had been recorded in main literature. But there is less comprehensive report of its usage in the other 55-minority nationality. This article was based on the analysis of ethnic minority literature of thousands of years, and conducted a comprehensive collation and analysis of mineral medicine. It was mostly determined that there was 20 minority groups using mineral medicine, with a total of 163 species (limited our references), and the most used is the Tibetan, accounting for 141. The most serious problems of mineral medicine are that species should be further investigated and researched, and then become the legal commercial medicine, and the classification principles of mineral medicine should be established. Through the traditional processing and experimental studies, the problems of attenuation and detoxification should be solved.

Objective The present study analyzed the performances of hearing impaired children and normal hearing children at age 3 on the open set monosyllables test to provide reference for rehabilitation .Methods 30 typi-cal children and hearing impaired children at age 3 were randomly selected and tested using the open -set monosylla-ble test in evaluation of auditory response to speech (EARS) .Results ① There were significantly differences be-tween different test items in both groups ,the decreasing order of the score was tone> vowel>consonant>word(P<0 .01) ,and the scores on vowels ,consonants and words of hearing -impaired children were respectively signifi-cantly lower than that in normal hearing children(P<0 .001) .②There were similarities and differences between the mistakes of typical children and hearing impaired children .Blade-palatals and laterals in both groups achieved the lowest accuracy .While the accuracies on bilabials ,labiodentals ,nasals and plosives were highest in typical children , the accuracy on velar was highest in hearing impaired children .And the accuracies of consonants and nasal vowels on each place and manner of articulation in hearing -impaired children were significantly lower .Conclusion The study showed that the performances on vowels ,consomants and words of hearing -impaired children aged 3 in the open set monosyllables test were poorer than that in normal hearing children .The main errors were between the same places or methods of articulation ,especially for Blade -palatals and laterals .It is possible related to the deficiency of lan-guage input with the hearing impairment and the age with HA/CI .

Objective To investigate the effects of environmental intervention on growth hormone (GH) and insulin-like growth factor 1(IGF-1) in very low birth weight infants in NICU.Methods 60 cases of very low birth weight infants were randomly divided into the experimental group and control group (30 cases in each group) in NICU from June 2012 to June 2013.By adjusting the light,reducing the noise,focusing the nursing time,the levels of growth hormone and insulin-like growth factor-1 were detected and the growth indexes were measured including body weight,length,and head circumference on the 7th day and 14th day.Results The indicators of growth and development in the experimental group on the 7th day and 14th day after birth were significantly better than those of the control group.The IGF-1 level in the experimental group on the 7th day was significantly higher than that of the control group.The GH and IGF-1 level in the experimental group was significantly higher than that of the control group.Conclusions Effective environmental intervention in NICU can improve the GH and IGF-1 lev-el of very low birth weight infants and improve their quality of life.
