Cataract and age-related macular degeneration (AMD) often present concurrently in aged persons. There has been a longstanding controversy among clinicians as to whether cataract surgery is contraindicated in eyes with AMD. Most of previous researches indicated that cataract surgery could accelerate the progression of AMD. However recently studies suggested that cataract surgery improved visual function of the patients and didn't accelerate the progression of AMD. These are related to the development of cataract surgery and the using of phacoemulsification technique.

This paper reports nursing of 11 patients undergoing laparoscopic radical cystectomy with orthotopic ileal neobladder. The nursing points included preoperative bowel care,psychological care,observation of drainage tubes and complications,guidance of pelvic floor muscle training and bladder training with timed voiding. Patients receiving bladder training after catheter removal,and got self-control urination in 2 weeks. Only a patient left urinary incontinence at night occasionally.

Next-generation sequencing (NGS) platforms have recently evolved to provide an accurate and comprehensive means for the detection of molecular mutations in acute myeloid leukemia(AML).The 54th ASH annal meeting reported lots of studies on NGS in AML,reflect the important role of the NGS technology in modern diagnosis and treatment of blood diseases and the impact on the future development of the blood disease.

TIMI Flow as a method to assess myocardial reperfusion has been employed clinically ever since 1980's.TIMI Frame Count grading is a more objective,repeatable and correlative in variablity than those of TIMI Flow.TMBG and TMP provide the reperfusion evaluation on myocardial microvascular level.Doppler contrast echocardiography could be used as an additional index to assess vessel recanalization and myocardial reperfusion.Moreover,MCE,continuous ECG monitoring of ST-segment,isotope imaging of myocardial reperfusion and myocardial-enhanced MRI can all be used as non-invasive evaluating approaches with great clinical value.(J Intervent Radiol,2006,15:250-253)

Objective To establish the determination of Dehydroandrographolide in Ganmaoqing Capsule. MethodsThe determination was carried out by HPLC with a KromasilC-18 column(250 mm ×4.6 mm,5μm),methanol-water(65:35)severed as the mobile phase,the speed was 1mL/min and the detection wavelength was at 254 nm. ResultsDehydroandrographolide showed a good linear relationship at the range of 0.04872 μg ～0.38976 μg(r2 =0.9995,n= 8);The average recovery of Dehydroandrographolide was 100.1%(RSD= 2.92%). ConclusionHPLC method was sensitive,accurate,reproducible,specific and could be used for quality control of Ganmaoqing Capsule efficiently.

ObjectiveTo analyze the neurological manifestations of chronic mercury poisoning for the improvement of clinical understanding of this disease.MethodsThe clinical data of 8 cases diagnosed as chronic mercury poisoning admitted in the department of neurology of Xuanwu hospital during the past 5 years were collected and analysed.Results Neurological manifestations of chronic mercury poisoning involved psychological problems,sleep disorders,ataxia,extremities weakness and atrophy,tremor,peripheral neuropathy and paresthesia.ConclusionsThere are various kinds of neurological manifestations of chronic mercury poisoning.Identification of these manifestations in clinical practice and early diagnosis are beneficial for the relief of pains in the patients.

The performance appraisal system of medical institutions serves as the cornerstone for hospital management. Thanks to the grow-th of information technology, information platform has grown into an indispensable tool for performance appraisal in hospitals as well. This paper focuses on the design and application of such a platform for performance appraisal, as well as the innovations on the appraisal contents and forms, setup and control methods for appraisal indicators, and the achievements made with such a platform.

The present investigation was undertaken to evaluate the role of the Chinese fruit juice in blocking nitrosamine formation in vitro.A model system simulated the conditions (pH 3.3, 37℃) known, to exist in the stomach, was used in the experiments. Different amount of nitrite and aminopyrine was incubated with Chinese fruit juice or vitamin C solution or buffer solution for 1 hr. 0.1 ml samples were taken and then subjected to the Ames mutagenicity test. The tester strain TA100 of Salmonella typhi-murium was employed for the detection of mutagenicity due to the N-nitro-samine formed from sodium nitrite and aminopyrine. Test samples and bacteria with or without S-9 mixed with molten top agar and poured onto the minimal agar plates. After incubation, the sample, that gave at least a 2-fold increase in induced revertants, compared to spontaneous revertants, was considered to have mutagenic activity.It showed that the concentration of the precursors was at or above 5 mg/ ml with S-9 and without juice. the samples exhibited mutagenic activity. It suggested that the nitrosamine was formed in this system. While the incorporation of Chinese fruit juice was found to inhibit the formation of nitrosamine at 5mg/ml and 8mg/ml. The cultures did not show mutagenic activity. The induced revertant colonies per plate was 252 ? 4.2. The Chin esefruit juice is more effective than that of vitamin C, the induced revertant colonies per plate was 445 ? 81.2, which shows mutagenic. The difference between the cultures of Chinese fruit juice and vitamin C is significant (P

ObjectiveTo investigate the etiology, exacerbating factors and outcome of geriatric patients with acute renal failure (ARF) in emergency and critical internal medicine. MethodsClinical features of elderly inpatients with ARF who were diagnosed in internal medicine of our hospital during the past 10 years were retrospectively analyzed. Patients were divided into community-acquired ARF (CA-AFR) group and hospital-acquired ARF (HA-ARF) group. Comparisons between CA-ARF group and HA-ARF group, and between elderly patients and non-elderly patients with ARF in internal medicine were performed. ResultsAmong 381 elderly ARF patients in internal medicine, there were 218 (57.2%) CA-ARF patients and 163 (42.8%) HA-ARF patients. Most of the HA-ARF patients (153 cases) were distributed in medical intensive care. Compared with CA-ARF group, patients in HA-ARF group were older, with more underlying diseases, a higher ratio of infections and/or heart failure and more severe acute renal failure. Infection and heart failure/severe myocardial isehemia were the major exacerbating factors for HA-ARF. Of the 163 patients with HA-ARF, 146 patients died and 17 patients survived. Patients in the death group had more underlying diseases, a higher ratio of severe infections and heart failure/severe myocardial ischemia, a higher ratio of cases with multiple organ dysfunction syndrome(MODS) and a higher score of APACHE Ⅱ.When compared with non-elderly patients with ARF, the elderly patients had a higher proportion ofHA-ARF, a higher ratio of MODS, a higher score of APACHEⅡ and a higher mortality of ARF.ConclusionsThe elderly critical patients are susceptible to HA-ARF with more chronic underlying diseases. Infection and heart failure/severe myocardial ischemia are the major exacerbating factors.The prognosis depends on the treatment of predisposing diseases and removal of exacerbating factors.
