Objective To analyze the inappropriate use of oral drugs in elderly patients admitted in internal medicine, and to guide clinical rational drugs use in elderly patients. Methods One hundred inpatients′ data over 65 years were collected in the department of geriatrics. The potentially inappropriate use of oral drug were analyzed according to the Beers criteria published in 2012 and drugs instructions. Results In 100 patients, (5.81 ± 2.78) kinds of oral drugs had been taken per inpatient. One patient was involved out-of-label usage. There were potentially inappropriate uses of oral drugs in 21 patients. Inappropriate use of oral drugs in three patients were not related to diagnosis or disease, and in 4 patients were related to morbid state, 14 patients used drugs that need to be used with caution in older adults. Conclusions There are off-label uses and potentially inappropriate medications in clinical practice, so clinical doctors should examine and assess the uses of drugs. Clinical doctors should strengthen the understanding and application of the comprehensive geriatric assessment.

Objective To compare the clinical effect of different doses of methylprednisolone in the treatment of children with severe hand foot mouth disease research and analysis. Methods 100 patients in our hospital from January 2014 to August 2016 were selected and randomly divided into the control group and the experimental group, with 50 patients in each group. The control group were treated with small doses of methylprednisolone, 2 mg/ (kg?d), intravenous injection. The experimental group was treated with large dose of methylprednisolone, 10~15 mg/(kg?d) intravenous infusion. The therapeutic effects of the experimental group and the control group were compared and analyzed. Results after the corresponding treatment, the number of adverse reactions in the experimental group was 31, the adverse reaction rate was 62.0%, and the adverse reaction rate in the control group was 60.0%. There was no significant difference in the incidence of adverse reactions between the two groups. The upper respiratory rate and critical illness in the experimental group were 26.0% and 32.0%, significantly lower than that of the control group (P<0.05). The average remission time of the patients in the experimental group was (2.19±1.01) days. The symptomatic remission time in the control group was (4.19±1.89) days. The remission time of the control group was significantly longer than that of the experimental group, with statistical difference (P<0.05). Conclusion The short term large dose of methylprednisolone in treatment of children with severe HFMD clinical effect is ideal, can be reduced to critical illness rate, less symptom remission time, with the further promotion of the clinical significance.

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.

Through morphological observation, HE staining, TRAP staining and toluidine blue staining of bone resorption pits to identify osteoclasts which obtained by 1α, 25-(OH)2 VitD3 inducing rabbit bone marrow cells. Three indicators-TRAP staining, TRAP enzyme activity detecting and the number and area of bone resorption pits were adapted to detect the effect of Sargentodoxae caulis on the activity of osteoclasts. Culturing MC3T3-E1 Subclong 14 cells and detecting the effect of S. caulis on differentiation and proliferation of them by MTT and detecting the alkaline phosphatase in cells. The results show that all of the low, middle and high doses of water and alcohol extracts of S. caulis have significant inhibition on osteoclast differentiation and bone resorption ability in a dose-dependent manner. The low and middle doses of water and alcohol extracts of S. caulis can stimulate differentiation and proliferation of MC3T3-ElSubclone 14 cells, which indicates S. caulis can prevent osteoporosis and the function could be achieved by inhibiting osteoclast activity and promoting the proliferation and differentiation of osteoblasts.

Objective To investigate and analyze the clinical and imageological features of skull base erosion in nasopharyngeal carcinoma( NPC). Methods 67 NPC patients proved by pathology were retrospectively reviewed. All patients underwent both CT and MRI plain plus enhancement scan. Scan slices were performed from oral pharynx (lower border of second cervical vertebra) to suprasellar cistern by axial CT scans and axial, sagittal and coronal MRI scans. Results (1) 52 patients with skull base erosion were found with MRI, and only 35 patients with CT. The following structures and figures were difined with CT and MRI respectively: pterygoid plates 8,14; clivus 22,25 ; petrous apex 25 ,28 ; sphenoid body or sinus 19,25; sphenoid wing 9, 12; cavernous sinus 14,17. The display difference between CT and MRI had statistical significance ( x2= 9. 47 , P = 0. 02). (2) CT- defined skull base erosion was most bone destruction , however, not only bone destruction but also tumor crossing skull base structure could be defined by MRI. (3) The incidence of headache was 82.7% (43/52) , cranial nerve palsy was 67. 3% (35/52) , both headache and cranial nerve palsy was 57. 7% (30/52). Conclusion Headache and cranial nerve palsy are primary characteristics of the skull base erosion in NPC. MRI is superior to CT in defining both bone erosion and brain tissue abnormality.
