Objective To characterize the clinical features of patients with cardiac amyloidosis (CA).Methods Totally 42 patients with CA admitted to Guangdong General Hospital since 2008 were included and retrospectively analyzed in the present study.CA was confirmed by abdomen and endocardium biopsy examination.Clinical manifestations,electrocardiogram and echocardiography were collected for the evaluation.Results Several clinic features are common in CA.In the present study,37 cases (88.1％) presented with chest tightness,dyspnea,20 cases(47.6％) with chest pain,27 cases(64.3％) with right heart failure,27 cases (64.3％) with fatigue,and 30 cases (71.4％) with renal insufficiency and proteinuria.Electrocardiogram (ECG) showed that 32 of the patients (76.2％) were with low voltage in limb leads,29 cases (69％) of them were with poor R wave progression in precordial leads,17 cases (40.5％) with ST-T change,28 cases(66.7％) with pseudo-necrotic Q wave and 36 cases (85.7％) with various kinds of arrhythmia.Echocardiography indicated that all of the subjects (100％) were with different degrees of left ventricular posterior wall or ventricular septal thickness,and left atrial hypertrophy with different degree of myocardial grain appearance or ground-glass opacity.Thirty-six cases (85.7％) were with pericardial effusion,and 27 cases (64.3％) were with abnormal left ventricular eject function.Conclusion For those who were with unexplained clinical cardiac insufficiency,renal insufficiency,myocardial hypertrophy,but normal of ventricular size in echocardiography and low voltage on ECG limb leads,a tissue biopsy from abdomen,labial glands or endocardium should be considered in the diagnosis of CA.

Objective To investigate the therapeutic effects of enhanced external counterpulsation (EECP) on cerebral edema and cerebral blood flow perfusion with MRI following cardiac arrest (CA) and on successful return of spontaneous circulation (ROSC) by cardiopulmonary resuscitation (CPR) in dogs.Methods Sixteen beagle dogs were induced CA with alternating current on epicardium,then were randomly (random number) divided into the EECP and control group after successful ROSC.MR scanning brain of all animals was carried out by diffusion-weighted imaging (DWI) and perfusion weighted imaging (PWI) before CA and on the first,second and third days after ROSC.Blood pressure,right common carotid artery flow,and intracranial microcirculation perfusion were measured.Results There were no significant differences in mean artery pressure at all intervals between two groups (P ＞ 0.05).There was significant increase in right common carotid artery blood flow and intracranial microcirculation of dogs in EECP group compared with the control group (P ＜ 0.05).Apparent diffusion coefficients (ADC) of water molecule on the first and third days after ROSC were significantly higher in the EECP group than those in the control group (P ＜ 0.05).Ratios of post-ROSC relative cerebral blood flow (RCBF) /original cerebral blood flow were higher in the EECP group than those in the control group on the first,second and third days after ROSC (P ＜ 0.05).Conclusions EECP treatment could improve cerebral blood flow perfusion and relieve ischemic cerebral edema,alleviating brain injury in dogs following CA and successful ROSC.

OBJECTIVEWe retrospectively analyzed the causes, diagnosis, clinical characteristics, treatment and prognosis of 17 patients with rhabdomyolysis.

METHODSRhabdomyolysis cases diagnosed from January 2005 to March 2014 in our department were included.

RESULTSA total of 17 rhabdomyolysis patients (male 13, mean age (60.4 ± 15.7) years) were analyzed.Four cases had coronary heart disease combined with hypertension, hyperlipaemia, atrial fibrillation, 10 cases had dilated cardiomyopathy combined with coronary heart disease, hyperlipaemia, atrial fibrillation, 8 cases had atrial fibrillation combined with hypertension, coronary heart disease, hyperlipaemia, 1 patient had pulmonary embolism combined with hyperlipaemia, 1 patient had aortic dissection combined with hypertension, 10 hypertension patients were combined with coronary heart disease, hyperlipaemia, atrial fibrillation, aortic dissection and 1 patient with ventricular tachycardia was combined with depression.Various degrees of liver and kidney dysfunction, reduced hemoglobin and myoglobinuria were found in all patients.Fever was found in 7 cases, relevant neurological signs in 5 cases. Digestive tract discomfort and muscle weakness or muscle pain symptoms were seen in all patients during hospitalization. All cases underwent renal replacement therapy and respirator was used in 14 patients to support breathing. Post therapy, 10 cases improved but 7 cases died. All 17 patients had history of statin use.

CONCLUSIONStatin may be the major cause of rhabdomyolysis in these patients, and the mortality of rhabdomyolysis is high despite various therapy stratigies.

Objective:To explore the effect of Internet + technical liaison service mode on the postoperative continuing nursing of elderly patients with osteoporotic hip fractures.Methods:A total of 92 elderly patients with osteoporotic hip fractures who were admitted into in Orthopaedics Department of the First Affiliated Hospital of Soochow University from July 2018 to December 2019 were selected, and randomly divided into intervention group and control group by random number table method, with 46 cases in each group. The control group was given routine follow-up outside hospital, while the intervention group was given the continuing nursing led by the orthopedic specialist nurses based on the Internet + Technology home orthopedic care platform. All patients were followed up to 6 months after operation, and the differences of Harris Hip Score (Harris), Numeric Rating Scales (NRS), Barthel Index, Short Form 36-item Health Survey (SF-36) between the two groups were compared.Results:The Harris scores were 49.74 ± 4.28, 76.59 ± 4.33 and 90.78 ± 2.61 in the intervention group, and 46.17 ± 3.85, 74.26 ± 4.24 and 88.65 ± 2.17 in the control group in 1, 3 and 6 months after operation, respectively. The differences were statistically significant ( t=-4.20, -2.60, -4.26, all P<0.05). The NRS scores in the intervention group were 1.33 ± 0.47, 0.83 ± 0.38 and 0.76±0.43 in 1, 3 and 6 months after operation respectively, while the NRS scores in the control group were 1.61 ± 0.54, 0.96 ± 0.42 and 0.84 ± 0.38, respectively. The difference in pain scores between the two groups was statistically significant only at 1 month after operation ( t=2.68, P<0.05). The Barthel Index in the intervention group were 61.74 ± 8.90, 93.80 ± 5.29 and 98.26 ± 2.83 in 1, 3 and 6 months after operation respectively, while those of the control group were 60.33 ± 5.81, 91.09 ± 7.52 and 97.83 ± 3.10, respectively. The difference in Barthel Index between the two groups was statistically significant only in 3 months after operation ( t=-2.00, P<0.05). The scores of SF-36 in the intervention group were 93.73 ± 3.89, 100.26 ± 3.77 and 107.50 ± 3.56 at 1, 3 and 6 months after operation respectively, while those of the control group were 92.67±3.42, 97.71±2.67 and 103.68±2.83, respectively. The difference in SF-36 scores between the two groups was statistically significant only at 3 and 6 months after operation ( t=-3.74, -5.71, P<0.05). Conclusions:The continuing nursing based on multi-disciplinary team cooperation in hospital + Internet + Technology home orthopaedic nursing platform led by orthopaedic specialist nurses can improve joint function, relieve pain and improve quality of life of elderly patients with osteoporotic hip fractures after operation.
