4.Vision disorders in the elderly
Chinese Journal of Geriatrics 2016;35(2):120-122
Visual impairment is one of the common problems in the elderly,and regular screening should be considered for early detection as well as prevention.This article describes some of the common causes of vision loss in older adults,including cataracts,age-related macular degeneration,ametropia (presbyopia) and diabetic retinopathy.Patients with senile cataract should be offered a manifest refraction in the early stage,and surgical treatments are indicated when their vision is less than or equal to 0.4.Prevention and treatment of age-related macular degeneration may be achieved through medication or dietary adjustment.Vascular endothelial growth factor can be used in the treatment of neovascularage-related macular degeneration.Patients with presbyopia are advised to obtain a manifest refraction.Patients with diabetic retinopathy should be regularly offered an ocular fundus examination and receive early treatment when necessary,with particular attention paid to glycaemic control.

BACKGROUND: The water extract of white mulberry root-bark plays certain roles in decreasing the blood glucose and blood lipids of rats, antagonizing inflammation and analgesia, relieving asthma and inducing diuresis,as well as relaxing the smooth muscle.OBJECTIVE: To analyze the hypoxic tolerance of white mulberry rootbark by using the hypoxic tolerance test under normal pressure, rapid head-cut test and the test of isoproterenol in enhancing myocardial oxygen consumption.DESIGN: A randomized control study.SETTING: Department of Pathology and Department of Pharmacology,School of Basic Medical Sciences, Gannan Medical College.MATERIALS: The experiments were conducted in the laboratory of the Scientific Research Center of Gannan Medical College between May and June in 2003. Totally 106 healthy adult Kunming mice were used in the following three independent experiments. The white mulberry root-bark extract was provided by the Department of Pharmacology of Gannan Medical College, injection of propranolole hydrochloride by Beijing Pharmaceutical Factory.METHODS: ① Hypoxic tolerance test under normal pressure: Forty mice were divided into four groups with 10 mice in each group according to the method of random number table: saline group, propranolol group, white mulberry root-bark extract groups treated with 0.10 and 0.20 mL/g respectively, and the mice were treated with intraperitoneal injection of saline (0.02 mg/g), propranolol (10 g/L), white mulberry root-bark extract (0.10 and 0.20 mL/g) respectively. After 15 minutes,the mice in the groups were placed into the enclosed 250mL ground and wide mouthed bottles separately, and the survival time of the mice was observed by taking the last breath as the index. ② Rapid headcut test: Thirty mice were divided into three groups with 10 mice in each group according to the method of random number table: saline group, white mulberry root-bark extract groups treated with 0.10 and 0.20 mL/g respectively, and the mice were treated with intraperitoneal injection of saline (0.02 mg/g), white mulberry root-bark extract (0.10and 0.20 mL/g) respectively. After 15 minutes, the heads of the mice were rapidly cut down without anesthesia, and the time from cutting head to the last breath was recorded. ③ Test of isoproterenol in enhancing myocardial oxygen consumption: Thirty-six mice were divided into three groups with 12 mice in each group according to the method of random number table: saline group, isoproterenol group and white mulberry root-bark extract group treated with 0.10 mL/g. In the saline group, the mice were injected with saline subcutaneously (0.03 mL/g),and then intraperitoneally (0.02 mL/g) after 5 minutes. In the isoproterenol group, the mice were firstly treated with subcutaneous injection of isoproterenol (0.015 mg/g), and the intraperitoneal injection of saline (0.02 mL/g) was given after 5 minutes. In the white mulberry root-bark extract group treated with 0.10 mL/g, the mice were firstly injected subcutaneously with isoproterenol (0.015 mg/g), and then injected intraperitoneally with white mulberry root-bark extract (0.01 mL/g)was given after 5 minutes. After 15 minutes, the mice were placed into the enclosed wide mouthed bottles separately, and the survival time of the mice was observed.MAIN OUTCOME MEASURES: The survival time of mice in each group was observed in the three independent experiments.RESULTS: All the 106 healthy adult Kunming mice were involved in the analysis of results. ① Effect of white mulberry root-bark extract on the survival time of mice in the condition of hypoxic tolerance under normal pressure: As compared with the saline group, the survival times in the propranolol group and white mulberry root-bark extract groups treated with0.10 and 0.20 mL/g were obviously prolonged [(36.2±4.3), (81.0±17.0), (66.4±8.9), (90.3±7.4) minutes, t=3.358-3.617,P < 0.01]. ② Effect of white mulberry root-bark extract on the survival time of mice under the condition of cerebral ischemia: As compared with the saline group, the times from cutting head to the last breath in the white mulberry root-bark extract groups treated with 0.10 and 0.20 mL/g were obviously prolonged [(17.8±1.3), (21.2±0.8), (23.5±0.7) minutes, t=2.824-3.432, P < 0.05 or 0.01]. ③ Effect of white mulberry root-bark extract on the survival time of mice under the condition of myocardial oxygen consumption enhanced by isoproterenol: As compared with the saline group, the survival time in the isoproterenol group was obviously shortened, but those in the white mulberry rootbark extract groups treated with 0.10 and 0.20 mL/g were markedly prolonged [(36.2±4.3), (27.9±2.6), (50.6±3.4) minutes, t=2.734-3.035, P < 0.05].CONCLUSION: White mulberry root-bark extract has obvious effect on hypoxic tolerance.

In order to study the association between lower urinary tract infection and cystitis glandularis (CG), 120 cases of CG were diagnosed by cystoscopic biopsy in the suspicious foci of the bladder. Among them, 72 cases were subjected to bacterial counting culture of urine and microscopic examination of urinary sediment, and 60 cases to fluorescence quantitative polymerase chain reaction (FQ-PCR) assay to detect HPV, CMV and HSV DNA in urine samples. In the 72 cases of CG, the positive rate of bacterial counting culture of urine was 15.3% (11/72), and gray zone rate was 18.1% (13/72). 31.9% (23/72) patients were positive in bacterioscopy of urinary sediment. There was statistically significant difference as compared with the control group (P<0.01). Only 4 of 60 urine samples were positive by FQ-PCR in detection of the three viruses mentioned above with the positive rate being 6.67%. Compared with the control group, there was no significant difference (P>0.05). It was concluded that the genesis of CG was closely correlated with the chronic lower urinary tract infection, especially caused by Esch coli.
