Objective To discuss the relationship of hypertension with ageing and comorbidities in 6426 inpatients. Methods The data of 6426 inpatients with hypertension from May 2005 to May 2009 were analyzed retrospectively. All inpatients were divided into four groups: the young-aged group from 18 to 44 yrs (n= 312, 4. 8%), the middle-aged group from 45 to 59 yrs (n= 1529,23.8%), the elderly group from 60 to 79 yrs (n=3847, 59.9%) and the old old group from 80 to 99 yrs (n=738, 11.5%). The percentages of hypertension patients in the same age group over the same period were calculated and the comorbidities were observed respectively. Results Of 6426 hypertensive cases, there were 3438 males (53.5%) and 2988 females (46.5%), ranging from 18 to 99 yrs with the average age of (66.3± 12. 1) yrs. There were 25 504 inpatients over 18 years old including 11 208 in the youth group, 5389 in the middle-aged group, 7596 in the elderly group and 1311 in the old old group. The proportions of hypertension inpatients to total in-patients in the four age groups were 2.8%, 28. 4%, 50.7% and 56.3% respectively. In the youth and middle-aged groups, numbers of males with hypertension were more than of females, however there was no significant difference in gender in the elderly and the old old groups. Within 6426 inpatients with hypertension, 2069 (32.2 %) had diabetes mellitus, 1508 (23.5%) had hyperlipidemia, 105 (1.6 % )had sleep apnea syndrome, 1061 (16.5%) had coronary artery disease, 904 (14.1%) had heart failure, 2353 (36.6%) had stroke and 678 (10. 6%) had kidney failure. Conclusions The prevalence of hypertension increases with ageing significantly. The correlated risk factors for hypertension include diabetes mellitus, hyperlipidemia and sleep apnea syndrome, being a clustering phenomenon, especially for elder patients. These risk factors also deteriorate the damage on heart,brain, kidney and other target organs, which might ultimately result in serious cardio-cerebral vascular events. Therefore, besides control of blood pressure, we should strengthen the complex treatment on hypertension to prevent and delay the occur of complicating diseases.

Objective To investigate the related risk factors in patients with atrial fibrillation in order to prevent and delay the occurrence of atrial fibrillation.Methods Five hundred and fifty-eight inpatients with atrial fibrillation were retrospectively analyzed from June 2005 to June 2008.They were divided into several groups according to the age and the characteristics of the elder patients with atrial fibrillation were analyzed.Results In the 558 cases with atrial fibrillation, there were 298 males (53.4%) and 260 females (46.6%) aged from 21 to 97 years.The average age was (72.8 ±10.1) years.There were 57 cases aged 21-59 years(10.2 %)and 501 cases aged 60-97 years(89.8 %).The total number of inpatients in our hospital was 11 869, and there were 4049 cases aged<60 years, 2527 cases aged 60-69 years, 3971 cases aged 70-79 years, 1244 cases aged 80-89 years and 78 cases aged>90 years.The proportions of the inpatients with atrial fibrillation in the above five age groups of inpatients were 1.4%(57 cases), 4.2%(107 cases), 6.6% (262 cases), 9.5%(118 cases)and 17.9% (14 cases), respectively.In 558 cases with atrial fibrillation, there were 230 cases (41.2%) with paroxysmal atrial fibrillation, 44 cases (7.9%) with persistent atrial fibrillation and 284 cases (50.9%) with permanent atrial fibrillation.The most common underlying disease was hypertension in the 558 cases, followed by coronary heart disease, heart failure, diabetes, rheumatic heart disease and so on.Conclusions The prevalence of atrial fibrillation is increased with aging.Hypertension, coronary heart disease, rheumatic heart disease, heart failure, hyperthyroidism,diabetes, chronic pulmonary disease and renal failure are all the risk factors for atrial fibrillation.

Objectives To report clinical,electrophysiological and pathological features of myopathy with tubular aggregates.Methods The onset of the disease was between 5-50 years old in the 6 sporadic male cases.Skeletal muscle biopsy was performed for all cases.Specimens were examined histochemically,enzymhistochemically and electromicroscopically.Results Case 1 and 2 presented with limb girdle myasthenic syndrome.The case 1 developed exercise-induced cramps in the late stage.Case 3 complained about persistent weakness and Dopa-responsive dystonia.Case 4 and 5 were characterized by periodic paralysis.Case 6 showed exercise-induced cramps.Serum potassium was normal in all patients. Slight elevation of serum creatine kinase appeared in 3 cases.Electromyography showed neurogenic pattern in case 1 and 6,myogenic changes in case 4 and 5,and no abnormality in other 2 cases.Marked decrement of active potential amplitude was noted with low frequency repetitive nerve stimuli in case 1 and 2.Four percent to forty percent of muscle fibers showed focal material accumulation in the fibers,which involved mainly type 2 fibers in all cases.The material was stained bright red material with modified gomori trichrome,intensive staining with nicotinamide adenine dinucleotide-tetrazolium reductase,lack activity of succinate dehydrogenase and ATPase.Electron microscopy confirmed bundles of parallel micro-tubular structure in the muscle fiber.Conclusions Myopathy with tubular aggregates has various clinical subtypes and electromyographic pattern.Dystonia or other systemic symptoms could be noted in this disease.The limb girdle myasthenic syndrome can also be accompanied with exercise-induced cramps.

OBJECTIVETo observe the effect of Shenshuaining Granule (SG) combined telmisartan on serum creatinine (SCr) levels and urinary albumin contents in diabetic nephropathy (DN) patients, and to explore its efficacy.

METHODSTotally 204 DN patients were recruited, and further assigned to 3 groups, i.e., the early DN group, the clinical stage of DN with normal renal function group, the clinical stage of DN with insufficient renal function group. Patients in the same group were randomly allocated to the telmisartan treatment group, the SG treatment group, and the combination of SG and telmisartan treatment group, 68 in each group. Patients in the telmisartan treatment group took telmisartan tablet, 80 mg per day, once daily. Those in the SG treatment group took SG, 5 g each time, 3 times per day. Those in the combination of SG and telmisartan treatment group took telmisartan tablet (80 mg per day, once daily) and SG (5 g each time, 3 times per day). The therapeutic course for all was 3 successive months. SCr levels, serum urea nitrogen (BUN),24 h urine microalbumin (24 h U-MA) were detected before and after treatment. Results In three different treatment groups, 24 h U-MA decreased after treatment in the telmisartan treatment group; SCr and BUN decreased after treatment in the SG treatment group; and 24 h U-MA, SCr and BUN decreased after treatment in the combination of SG and telmisartan treatment group (P<0.05). In the clinical stage of DN with insufficient renal function group, SCr obviously increased after treatment in the telmisartan treatment group (P <0. 05). In the 3 DN stages, SCr and 24 h U-MA obviously decreased in the combination of SG and telmisartan treatment group, when compared with the telmisartan treatment group and the SG treatment group (P<0.05). Compared with the telmisartan treatment group, SCr and BUN obviously decreased in the SG treatment group, but 24 h U-MA quantitation obviously increased (P<0.05). BUN obviously decreased in the combination of SG and telmisartan treatment group (P<0. 05).

CONCLUSIONThe combination of SG and telmisartan could decrease urinary albumin, and stabilize SCr levels.
