Objective To determine the efficacy and safety of acarbose in the treatment of senile postprandial hypotension (PPH). Methods Forty three senile in-patients with PPH were recruited. Blood pressure and heart rate(HR) were recorded for 120 minutes by using non-invasive ambulatory blood pressure monitoring system. The participants had semiliquid standard meals with or without acarbose on two following days. The ejection fraction(EF) and fractional shortening(FS) were measured by two dimensional echocardiography before treatment. Results The magnitudes of the falls in systolic, diastolic and mean arterial blood pressure (SBP、DBP、MAP) (all P

Objective To research the relationship between binocular acuity and monocular acuity,and their effect on the evaluation of visual impairment and disability. Methods 1006 patients, aged between 18 and 60 years, are measured monocular and binocular acuities after the best lens correction. Results Binocular vision is higher than, equal to and less than monocular vision, three accounted for 27.14%, 70.78% and 70.78% respectively. Interocular difference has certain correlation with binocular interactions (χ2=54.939,P<0.05,r=0.228). Thirty-three patients have same binocular acuity but different monocular acuity. Conclusion Binocular acuity associated with the monocular acuity and the better eye vision plays a special role in visual disability evaluation.

Laser techniques are widely applied in medical research and military affairs. The characters of laser make it the best way to evoke pain.Pain induced by laser stimuli is influenced by laser parameters such as wavelength, pulse duration and stimulus area in addition to the properties of skin such as the distance from the brain, type and color of skin. In this review,both laser evoked pain and factors influencing it are discussed.

To investigate the protective effect of Yindan Pinggan Capsules(YDPG)on acute alcoholic liver inflammatory injury and oxidative stress,sixty male Sprague-Dawley rats were divided into 6 groups randomly:normal group,model group,YDPG-L group,YD-PG-M group,YDPG-H group and Haiwang Jinzun(HWJZ)group.Except for the normal rats,while the remaining rats were administered orally with alcohol(50%,5 g·kg~(-1)).One hour after drinking,the rats in normal or model group were administered orally with PS,while the remaining rats were separately given YDPG(0.15,0.3,0.6 g·kg~(-1))or HWJZ(0.3 g·kg~(-1))for 10 days.After the last intragastric administration and fasting for 8 h,the HE staining was used to observe the pathological changes.The serum was used to determine the content of ALT,AST,ALP,TB,TP,LDH.The expressions of IL-1β,TNF-α,IL-10 and IL-4 in serum were detected by enzyme-linked immuno sorbent assay(ELISA).The content of SOD,MDA,GSH,GSP-Px in liver were determined.The results showed that both YDPGand HWJZ alleviated the liver injury induced by alcohol,decreased the activities of ALT,AST,ALP and LDH,down-regulated the expressions of TNF-αand IL-1β,up-regulated the expressions of IL-4 and IL-10;increased the activities of SOD,GSH,GSH-Px,but decreased the content of MDA.Therefore,the above results indicated that YDPG could protect the liver from alcoholic injury.

Abstract: Objective　To analyze the epidemiological characteristics of public health emergencies in Xishuangbanna Dai Autonomous Prefecture from 2012 to 2021, and to provide reference for formulating relevant prevention and control measures. Methods　The data of public health emergencies reported in Xishuangbanna from 2012 to 2021 were collected and analyzed through the China Disease Prevention and Control Information System. Results A total of 78 public health emergencies (including "Unrated" events) were reported in Xishuangbanna from 2012 to 2021. The highest 21 cases and the lowest 3 cases were reported every year. A total of 1 0374 cases were reported in 78 public health emergencies, involving a population of 1 703 049, with a morbidity of 609.14/100 000, 24 deaths, mortality of 1.41/100 000 and fatality rate of 231.35/100 000. The event level was mainly "general (level Ⅳ)" with 52 incidents, accounting for 66.67%, and 17 incidents of "major (level Ⅲ)", accounting for 21.79%. 51 cases were mainly infectious diseases, accounting for 65.39%. The peak periods for incidents were May-July and November-February of the next year; there were 39 incidents in schools, accounting for 50%, followed by 20 incidents in families, accounting for 25.64%. The top three reported cases were food poisoning (32.05%), chicken pox 17 (21.79%) and dengue fever 10 (12.82%). Among the 24 deaths in public health emergencies, 22 were caused by food poisoning. Wild bacteria poisoning and alcohol poisoning were the main causes of food poisoning, accounting for 45.83% and 37.5% of the total deaths, respectively. Conclusion Infectious diseases, especially respiratory diseases and food poisoning are the focus of the prevention and control of public health emergencies in Xishuangbanna Dai Autonomous Prefecture, of which Schools and families should be pay close attention. Plague, a Class A infectious disease, caused by the bacterium Yersinia pestis has occurred in two inter-animal outbreaks in 10 years and spread to the population, which should be of great concern.

Objective To evaluate the clinical efficacy of multiple stents placement in the management of hilar cholangiocarcinoma,especially in the complex cases of which the hepatic ducts are invaded.Methods Forty-five consecutive patients with hilar cholangiocarcinoma were treated with percutaneous transhepatic placement of two or three self-expandable metallic endoprostheses.The cause of hilar obstructions in these patients were all cholangiocarcinoma,including Bismuth classification type Ⅱ(n 12 ),Ⅲa(n 17),Ⅲb(n 10),and Ⅳ(n 6).Two or 3 stents were placed in the configuration of T,Y or X over the strictures.Results Stent placement with 2 or 3 endoprostheses was successful in all patients.All patients showed significant decrease in serum bilirubin level.The mortality rate within 30 days of stent placement was 2.2%(1/45).The mean survival and stent patency times were 215.3 d(26— 516 d)and 181.5 d(26—473 d),respectively.Conclusion Deploying of multiple metallic stents is an effective method to treat complex hilar cholangiocarcinoma,especially for the cases of which hepatic ducts are invaded:the henatic ducts should be drained as much as nossible.

Objective To investigate the relationship between quality of life and liver function in patients with chronic viral hepatitis B.Methods Psychological condition was investigated in 536 patients of chronic viral hepatitis B and 200 normal volunteers with self-administered 36-item short-form health survey questionnaire.These patients were divided into four groups based on their liver fuction normal,mild, moderate and severe damage,based on their serum activity of alanine aminotransferase(ALT)and serum level of bilirubin at the time of investigation.The patients with abnormal liver function at the beginning of the study would be retested when liver function recovered to normal level.Before and after comparison was made for those with abnormal liver function by Wilcoxon signed rank test.Trend test for the changes in liver function was performed by Jonckheere-Terpstra test.Results There was significant difference in physical functioning,role limitation due to physical health,bodily pain,general health perception,vitality,social functioning,role limitation due to emotional problems and mental health between patient with chronic viral hepatitis B and healthy volunteers.It was positively correlated with the degree of liver function damage. Scores of general health perception,role limitation due to physical health,role limitation due to emotional problems and vitality were relatively low in patients with chronic viral hepatitis B.Conclusions Quality of life in patients with chronic viral hepatitis B was far worse than that in healthy normal people,which related with their liver function.The more damage to liver function,the worse quality of life.Additional psychological treatment will be helpful for the patients with chronic viral hepatitis B other than drug treatment.

Objective To investigate the effects of different concentrations of glucose on growth and collagen synthesis of rat skin fibroblast cells cultured in vitro. Methods Rat skin fibroblast cells cultured in vitro were treated with glucose of different concentrations (30,35 and 40mmol/L) for 48 h (high glucose group 1,2 and 3). Cell proliferation was detected by MTT method,the hydroxyproline contents in culture media were determined by the commercial kit,and the mRNA expression of typeⅠand Ⅲ procollagen,matrix metalloproteinase-2(MMP-2)and tissue inhibitor of metalloproteinase-2(TIMP-2)were detected by RT-PCR. Cells cultured with 25mmol/L glucose were served as controls. Results With the increase of glucose concentration in culture media,the growth of skin fibroblast cells was significantly inhibited,and the hydroxyproline contents were significantly decreased (P
