Objective:To understand the comprehensive geriatric assessment (CGA) scores in chronic kidney disease (CKD) patients aged 65 years and older, and analyze the related influencing factors of quality of life.Methods:A total of 189 patients who were over 65 years old and diagnosed with CKD in the Department of Nephrology of Shanxi Provincial People's Hospital from October 2016 to October 2019 were included retrospectively. The patients were divided into dialysis group ( n=90 cases) and non-dialysis group ( n=99 cases) according to whether dialysis or not. The concise CGA scores included age, basic activities of daily living (BADL), instrumental activities of daily living (IADL), and modified cumulative illness rating score for geriatrics (MCIRS-G). Pearson correlation analysis was used to analyze the relationship between different scale scores and clinical indexes. Multiple linear regression analysis was used to further analyze independent related factors of the quality of life in elderly CKD patients. Results:Compared with the non-dialysis group, the BADL score and IADL score in the dialysis group were significantly reduced [(70.00±33.28) vs (93.38±14.32), t=6.166, P<0.001; (9.78±7.12) vs (15.95±5.74), t=6.520, P<0.001], while the MCIRS-G score was significantly increased [(31.13±4.00) vs (27.29±5.17), t=-5.741, P<0.001]. Linear regression analysis performed on the data of non-dialysis group patients showed that estimated glomerular filtration rate (eGFR), serum uric acid (SUA), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), blood potassium and chlorine were positively correlated with BADL and IADL scores (all P<0.05). B-type natriuretic peptide (BNP) was negatively correlated with BADL score ( P<0.01). BNP and age were negatively correlated with IADL score (both P<0.05). Fasting blood glucose (FBG) was positively correlated with MCIRS-G or MCIRS-G other than kidney (both P<0.05), and eGFR, SUA, total cholesterol, and HDL-C were negatively correlated with MCIRS-G or MCIRS-G other than kidney (all P<0.05). Multiple linear regression analysis showed that eGFR was an independent influencing factor for BADL ( P<0.01). Age and eGFR were independent influencing factors for IADL (both P<0.05). Conclusions:The decline of quality of life in elderly CKD patients is related with eGFR, SUA, age, BNP and HDL-C levels, and eGFR and age are independent influencing factors.

Objective To investigate the expression of steroidogenic factor 1 ( SF-1 ) in eutopic endometrium,ovarian endometriosis (EM) and adenomyosis.Methods From Jan.2008 to Dec.2010,30 patients with both ovarian endometriotic cysts and adenomyosis underwent hysterectomy,cystectomy or adenxectomy in Peking University First Hospital.The combination of ovarian EM and denomyosis were confirmed in 17 cases.In the mean time,endometria form 10 patients with cervical intraepithelial neoplasm ( CIN ) Ⅲ underwent hysterectomy were selected as controls.The expression of SF-l in eutopic endometrium,ovarian EM and adenomyosis was detected by immunohistochemistry staining.Results No immunoreactivity of SF-l was observed glandular cell and stromal cell in eutopic endometrium of both groups.14/17 of positive rate of SF-l were observed in lesions of ovarian endometriosis.SF-l protein was not expressed in the endometrial glandular cells of ovarian EM and in adenomyosis foci.Conclusion The differences of SF-l expression in ovarian endometrioma and adenomyosis foci might mediate the development of the disease.

Objective To evaluate the influence of narrow-band ultraviolet B on lesional microvessel density (MVD),vascular endothelial growth factor (VEGF),matrix metalloproteinases 2 (MMP-2)as well as on serum VEGF in patients with psoriasis vulgaris(PV).Methods Fifteen patients with PV were recruited into this study with 10 normal human controls.All patients received NB-UVB phototherapy thrice a week for 4-5 weeks.Prior and after the treatment,psoriasis area and severity index (PASI)was calculated,tissue specimens were taken from non-photoexposed lesions,and sera samples were obtained from these patients.Then,MvD and the expression level of VEGF and MMP-2 were measured by immunohistochemical labeled dextran polymer(LDP)method in the tissue specimens.Also,the serum level of VEGF was tested by enzyme-linked immunosorbent assay(ELISA).Results PASI score remarkably decreased in patients after the photothempy(t=13.35,P＜0.01).The MVDs were 20.52±5.02,7.33±1.24 and 4.26±0.79 capillaries per high power field(400 × amplification),in psoriatic lesions before treatment,after treatment,and normal control tissues,respectively,with a significant difference among the three groups (F=97.57,P＜0.05),and a significant increase was observed in the lesions before treatment compared with those after treatment and normal controls.The serum level of VEGF was 307.55±121.65 ng/L in psoriatic lesions before treatment,significantly higher than that after treatment(163.92±95.57 ng/L),and in normal control skin (139.78±79.06 ng/L),whereas there was no significant difference between the latter two groups(P＞0.05).The positivity rate of MMP-2 was similar among the three groups without statistical difference(P＞0.05).In psoriatic patients,a positive correlation was observed among PASI score,MVD,lesional and serum VEGF levels(P＜0.05),also among the MVD,VEGF and MMP-2 levels in lesions(P＜0.05).but lesional MMP-2 was unrelated to PASI score or sgrum VEGF(both P＞0.05).Conclusions NB-UVB may regulate superficial dermal microvascular proliferation by acting on the expression of VEGF in sera and lesions of psoriatic patients.VEGF and MMP-2 may bOth participate in the proliferation process of microvessels,while MMP-2 is unlikely to be involved in the therapeutic mechanism of NB-UVB.

Targeting dosage form is a kind of targeting drug delivery system which can be used to lock drugs aroud the target organs, tissues, cells and obtain more effective treatment for dose concentration, thus reducing the side-effects of such drugs while increasing their effeciveness. Targeting dosage form is the fourth-generation drug dosage form and it is ideal system for administration because it release the theraping drugs in the targeting-site. Particular emphasis was placed on liposome due to it was used as a drug carrier. Meanwhile, the highlights of research were on magnetic and enzyme targeting preparations. In addition, oral colon targeting drug delivery system, drugs were carried to ileocecum and release to get local and whole effect, is also an important part of targeting dosage form. The study on traditional chinese medicine (TCM) targeting dosage form is still at beginning stage in China. At present, most of study on TCM and natural products targeting drugs were focus on simple effective component and merely on TCM effective positions in relative with the difficult for determing their quality standard and procedure of preparing. It is the kernel item for TCM modernization and the key for TCM internationalization to develop new dosage form and new technology of TCM. There is a need in collaboration with multiple discipline. It will be a important research subject to develop TCM targeting preparation in the near future. TCM targeting dosage form can be classified into liposome, nanoparticles, multiple emulsion etc according to the difference of carrier and oral, rectal, colonic, nasal, dermal, ocular system on a basis of administration and so on. This paper made a summary on TCM and natural products targeting dosage form according to different targeting positions and introduce the procedure of preparing compared with the effect in vivo and manifest that TCM and natural products targeting dosage form will have good exploit prospect.

Objective To study the determination method of total flavonoids in Gansu Astragali Radix and Hedysarum Polybotrys. Methods Calycosin glycosides etc. was selected as reference substances, comparison on the difference of absorption curves was done by ultraviolet spectroscopy and colorimetric method (NaNO2-Al(NO3)3-NaOH, AlCl3, Mg(Ac)2, NaOH, phosphomolybdic acid, HCl-Mg power). Results With colorimetric method, the maximum absorption wavelength of referrence and the test was inconsistent. The absorption peak shape was also different. With UV method, Calycosin glycosides in band Ⅱ (260 nm) showed a shoulder absorption. Astragali Radix and Hedysarum Polybotrys also showed characteristic shoulder absorptions in band Ⅱ with absorption wavelength at 263 nm and 265 nm. So the sample absorption wavelength is basically the same as that of the control sample. Conclusion Colorimetries usually used for determination of total flavonoids are not suitable for the comparison determination of Gansu Astragali Radix and Hedysarum Polybotrys. It is suitable for determining the contents of total flavonoids in samples by UV spectrophotometry at the band Ⅱ, which is the characteristic absorption band of isoflavone compound.

Objective To investigate the effectiveness of Varenicline combined with MEDCHART application software for health education and follow-up in patients at smoking cessation clinic.Methods A total of 104 cases who had smoking cessation counseling and intervention at smoking cessation clinic from February 2014 to January 2015 were divided randomly into MEDCHART APP group (n=51) and conventional group (n=53).Both groups were intervened by brief admonishment and given Varenicline.The 9-12 weeks and 26th week protracted continuous abstinence rates were observed.Results There were no significant difference in 9-12 week protracted withdrawal rate between 26th week APP and conventional groups (56.9％ vs.45.3％),the 26th week abstinence rates in group MEDCHART APP (41.2％) were significantly higher than the conventional group (20.8％)(x2=5.088,P＜0.05).There was significant difference in full course completion rates between the two groups;15 cases (29.4％) completed the course in group MEDCHART APP,whereas 5 cases (9.4％) did so in conventional group (x2=4.405,P＜0.05).Conclusion MEDCHART APP can strengthen health education and follow-up,which helps extend the time for Varenicline,increase 26th week smoking cessation withdrawal rate.It is a useful tool for smoking cessation education and follow-up.
