The case here was relieved the nephrosis symptoms with the treatment. [Conclusion] Teacher He Lingzhi has rich clinical experience in treating IgA nephrosis with differentiation of signs, with definite cure effect.

A new dynamic in vitro intestinal absorption model for screening and evaluating lipid formulations was established by means of the characteristics of the intestinal digestion and absorption of the lipid formulations. This model was composed of two systems, including intestinal digestion and the intestinal tissue culture, which drew the evaluation method of intestinal absorption into the in vitro lipolysis model. The influence of several important model parameters such as Ca2+, D-glucose, K+ on the two systems of this model has been investigated. The results showed that increasing of Ca2+ concentration could be significantly conductive to intestinal digestion. The increasing of D-glucose concentration could stepped significantly down the decay of the intestinal activity. K+ was able to maintain intestinal activity, but the influence of different concentration levels on the decay of the intestinal activity was of no significant difference. Thus the model parameters were set up as follows: Ca2+ for 10 mmol x L(-1), D-glucose for 15 mmol x L(-1) and K+ for 5.5 mmol x L(-1). Type I lipid formulation was evaluated with this model, and there was a significant correlation between the absorption curve in vitro and absorption curve in vivo of rats (r = 0.995 6, P < 0.01). These results demonstrated that this model can be an attractive and great potential method for the screening, evaluating and predicting of the lipid formulations.

This paper report the development of a new dosage form - self-microemulsifying mouth dissolving films, which can improve the oral bioavailability of water insoluble drugs and have good compliance. A three factor, three-level Box-Behnken design was used for optimizing formulation, investigated the effect of amounts of microcrystalline cellulose, low-substituted hydroxypropyl cellulose and hypromellose on the weight, disintegration time, cumulative release of indomethacin after 2 min, microemulsified particle size and stretchability. Optimized self-microemulsifying mouth dissolving films could fast disintegrate in (17.09 +/- 0.72) s; obtain microemulsified particle size at (28.81 +/- 3.26) nm; and release in vitro at 2 min to (66.18 +/- 1.94)%. Self-microemulsifying mouth dissolving films with broad application prospects have good compliance, strong tensile and can be released rapidly in the mouth through fast self-microemulsifying.

Solid carriers had important effects on the properties of solid self-microemulsifying drug delivery systems (S-SMEDDS). In order to make the basis for further development of S-SMEDDS, the influences of silica on the absorption of S-SMEDDS were investigated. An in vitro lipolysis model was used to evaluate the influence of silica on self-microemulsifying drug delivery system digestion from intestinal tract. S-SMEDDS containing silica were prepared by extrusion/spheronization. The drug release and absorption were investigated. The results showed that lipolysis rate and drug concentration in aqueous phase after intestinal lipolysis both increased by adding silica, which was benefit to drug absorption. And silica was not benefit to absorption for slowing drug release. Consistently, there was no significant influence of silica on intestinal absorption. This study implied that the influences of silica on lipolysis rate and drug release were both amount dependent and it is suggested that silica could be used as the solid carrier but the proportion needs to be optimized.

Objective To understand the quality of care for disabled elderly persons in ethnic areas and its influencing factors.Methods A questionnaire survey was carried out using multi-stage stratified random cluster sampling method for the disabled elderly persons in ethnic minority areas,and the relevant factors affecting the quality of care were analyzed.Results The object with different regions,ethnicity,marital status,residence and social support condition,education degrees,health status,the degree of disabilities affecting their life,occupations,income showed different scores in each dimension of care quality.Multiple linear regression analysis showed that other ethnic people with disabilities,unmarried,unemployed/laidoff people with disabilities,disabilities extremely influenced the quality of life affected the total score of care quality.Conclusions To improve the financial aid for disabled elderly people in ethnic areas,attach great importance to the physical and mental care of unmarried disabled elderly people,perfect and establish effective handicapped rehabilitation mechanism,can improve the care quality of disabled elderly people.

Objective To explore the relationship of human papilloma virus (HPV) genotype and loading dose with development of cervical intraepithelial neoplasia (CIN) or squamous cell carcinoma of the cervix ( SCC),and explore the relationship of HPV genotype and CIN or SCC.Methods One hundred and twenty four patients in Sun Yat-sen Memoral Hospital of Sun Yat-sen University with CIN or SCC from September 2005 to December 2010 were selected in this study.HPV DNA was detected by Hybrid capture Ⅱand flow-through hybridization and gene chip.The relationship between the infection of HPV and CIN or SCC was analyzed.The influencing factors of CIN or SCC were analyzed by logistic regression.Results The total detection rate of HPV was 75.8％,and it was 44.4％,70.0％,95.7％ and 76.2％ in CIN Ⅰ,CIN Ⅱ,CIN Ⅲ and SCC group,respectively.The detection rate of HPV in high-grade lesion group ( 84.5％ ) was higher than low-grade lesion group(44.4％ ).The median of HPV load decreased in order as CIN Ⅲ,SCC,CIN Ⅱ and CIN Ⅰgroup.Infection of multi-genotypes or single genotype of high-risk HPV accounted for 97.9％.In logistic regression,HPV loading dose had significant influence on degree of cervical lesion.Conclusions Infection of HPV is a main etiological factor for SCC.There is some kind of correlation between HPV loading dose and development of SCC.

Background:Helicobacter pylori(Hp)is an important pathogen for peptic ulcer and gastric cancer,and is reportedly associated with a variety of extragastrointestinal diseases. However,there is no body fluid detection technique for Hp infection in clinical practice. Aims:To identify Hp infection-associated differentially expressed proteins in urine with relative molecular mass more than 10 kDa and provide potential biomarkers for diagnosis of Hp infection through body fluid detection. Methods:Midstream urine was collected from volunteers in the morning,and 13 C-urea breath test was performed to determine Hp infection. Each of 15 Hp-negative and 15 Hp-positive urine samples were mixed respectively for protein extraction. Spectra data were acquired by high performance liquid chromatogram-mass spectrometry,and label-free technology was used for relative quantitative analysis. The other 26 urine samples(15 Hp-negative and 11 Hp-positive) were used for validation by full scan. IPA software was employed for bioinformatics analysis. Results:A total of 475 urinary proteins were detected by label-free quantitative analysis and 42 differentially expressed proteins were identified. Finally,11 significantly up-regulated differentially expressed proteins were confirmed by external scanning validation. Bioinformatics analysis revealed the molecular functions,biological pathways,and related diseases of these differentially expressed proteins. Conclusions:These 11 differentially expressed proteins more than 10 kDa identified in urine might be potential biomarkers for diagnosis of Hp infection and provide molecular evidence for the correlation of Hp infection with extragastrointestinal diseases.
