Objective:To explore the effect of hemodialysis and conventional treatment on the heart function of elderly patients with chronic renal heart syndrome(CRCS).Methods:Sixty elderly patients with CRCS who were admitted to Qinhuangdao Port Hospital from July 2017 to July 2018 were selected and divided into the observation group (received hemodialysis and conventional treatment) and the control group (received conventional treatment) according to the random number table method, each group with 30 patients. The levels of left ventricular end-systolic dimension (LVESD) and left ventricular end-diastolic dimension (LVEDD), left ventricular ejection fraction (LVEF) and left atrium anterior and posterior diameter (LAD) before and after treatment of two weeks were compared between two groups, the levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP), blood urea nitrogen (BUN), cystatin C (CysC), creatinine (Cr) and tumor necrosis factor (TNF)-α, high sensitivity C-reactive protein (hs-CPR), interleukin 6 (IL-6) before and after treatment for two week were compared between two groups, and the safety of the two treatment methods was evaluated.Results:After treatment, the levels of LVESD, LVEDD, LAD in the observation group were lower than those in the control group: (26.13 ± 1.28) mm vs. (29.09 ± 1.26) mm, (47.58 ± 1.22) mm vs. (51.34 ± 1.49) mm, (30.02 ± 0.83) mm vs. (33.15 ± 1.02) mm, the level of LVEF in the observation group was higher than that in the control group: (39.63 ± 5.21)% vs. (35.77 ± 4.93)%, the differences were statistically significant ( P<0.05). After treatment, the levels of NT-proBNP, BUN, CysC and Cr in the observation group were lower than those in the control group: (1 089.31 ± 243.29) ng/L vs. (2 990.56 ± 531.22) ng/L, (16.08 ± 3.35) mmol/L vs.(21.93 ± 4.21) mmol/L, (0.35 ± 0.11) mg/L vs. (0.57 ± 0.18 mg/L, (251.62 ± 29.28) μmol/L vs. (290.66 ± 38.12) μmol/L, the differences were statistically significant ( P<0.05). After treatment, the levels of TNF-α, hs-CPR and IL-6 in the observation group were lower than those in the control group: (149.26 ± 19.53) μg/L vs. (182.33 ± 20.25) μg/L, (4.02 ± 1.33) mg/L vs. (5.38 ± 1.57) mg/L, (18.91 ± 3.11) μg/L vs. (22.45 ± 3.82) μg/L, the differences were statistically significant ( P<0.05). The incidence of adverse reactions during the treatment in the two groups had no significant difference ( P>0.05). Conclusions:The use of hemodialysis on the basis of conventional treatment can improve the heart and kidney function of elderly patients with CRCS, and this method is beneficial to alleviate left heart dilation and inflammation. It is a safe and effective treatment method.

Objective: To evaluate the efficacy and safety of maintenance therapy with reduced dose of rhTPO in the patients with primary immune thrombocytopenia (ITP) who attained stable platelet (PLT) counts after daily administration of rhTPO. Methods: Treatment was started with a daily administration of rhTPO (300 U/kg) for 2 consecutive weeks. Patients who attained stable PLT≥50×10⁹/L were enrolled to maintenance therapy starting with every other day administration of rhTPO, then adjusted dose interval to maintain platelet count (30-100) ×10⁹/L. Results: A total of 91 eligible patients were enrolled. Fourteen patients discontinued the study due to noncompliance (12/14) and investigator decision (2/14) . Among 77 patients who completed the study, 38 patients with the administration of rhTPO at every other day or less could maintain PLT≥30×10⁹/L for 12 weeks. The percentage of patients with a platelet response (PLT≥30×10⁹/L) at 4^th week, 8^th week and 12^th week of maintain therapy was 92.6% (63/68) , 82.7% (43/52) and 85.0% (34/40) , respectively. Median platelet counts remained in the range of (70-124) ×10⁹/L. The overall incidence of rhTPO-related adverse events was 7.7%. All the adverse events were generally mild. Conclusion Extending the dose interval of rhTPO is feasible to maintain stable platelet count in the patients with ITP, but the optimal dose interval is uncertain and might vary with individuals.

Objective To investigate the effects of repetitive transcranial magnetic stimulation (rTMS) on motor recovery in patients with incomplete spinal cord injury （SCI）. Methods 22 patients with T5～T12 incomplete spinal cord injury (ASIA C) were randomly divided into rTMS group and control group. 12 ptients in rTMS group were treated with 10Hz rTMS （10×5 s with 2 min interval) on motor cortex and rehabilitation. 10 patients in control group treated with rehabilitation only. They were assessed with ASIA motor score, ASIA pin prick score, ASIA light touch score, range of motion (ROM) of legs in antigravitation position, walking index for spinal cord injury Ⅱ (WISCIⅡ) and functional independence measure (FIM) score before and 4 weeks after treatment. Results There was no difference between two groups with the clinical assessment before treatment （P>0.05）. The ASIA motor score, ROM of legs and FIM score improved in both groups after treatment （P<0.05）. The score of WISCIⅡ also improved in rTMS group （P<0.05）, and ASIA motor score improved more in rTMS group than that of control group （P<0.05）. Conclusion rTMS can facilitate the recovery of the motor and walking function in patient with incomplete spinal cord injury.

Objective:To examine the reliability and validity of the telephone version of Information-Memory-Concentration Test (T-IMCT) in screening dementia when administered by telephone To evaluate the relation of the face-to-face and the telephonic interview for assessing the cognitive status Methods:T-IMCT was adapted from Information-Memory-Concentration test for the telephonic interview 65 subjects with dementia and 67 normal control subjects were examined by an experienced clinician, including clinical, neuropsychological and instrumental examination (CT or MRI) T-IMCT was administrated by telephone after 2 weeks, comparing the score from face-to-face interview with telephonic interview 20 subjects were administered the test twice by the same doctor to measure the test-retest reliability, and another 20 subjects were administered the test by two doctors to measure the inter-rater reliability Informants supervised the subjects to insure the authenticity of assessment administered by telephone Results:T-IMCT achieved a sensitivity of 80% and specificity of 80 6% in differentiating demented from healthy control subjects There was a high correlation between face-to-face interview and telephonic interview, Pearson’s correlation coefficient was 0 92 (P

Objective:To observe the reliability and validity of the Chinese version of Telephone In-terview for Cognitive Status-Modified (TICS-m). Methods:62 dementia patients and 63 community-dwelling healthy eldly individuals were assessed. TICS-m was examined by telephone and face-to-face. Results:The correlation between face-to-face and telephone interview was 0.79~0.97.The spearman correlation coefficient of inter-rater reliability were 0.89-0.97 and intra-rater reliability 0.91-0.98. The sensitivities of TICS-m and the memory factor score were both high. The TICS-m and three parts were all significantly correlated with MMSE and CDR. Conclusion:Face-to-face and telephone interview of TICS-m was highly correlated. In-ter-rater reliability and intra-rater reliability were good. The TICS-m is valid and reliable when used to screen dementia, especially mild dementia.
