Objective To prove the clinical effect of portable auto-haemostat machine on body's limbs. Methods Portable auto-haemostat machine was applied to the indicated patients in their clinical aid treatments course, i.e. the rapid hemostasis on limbs. Results The hemostasis was rapid and accurate with hemostatic pressure in the range from 190 to 230 mmHg. The excellent effect guarantees the diagnosis, observation, bandaging and secure transmission of victims until they were sent to the operation room. Conclusion It is reliable to use portable auto-haemostat machine on body's limbs in clinic works.

Objective To study the pathogenesis of osteoporosis in patients with liver cirrhosis following hepatitis B virus(HBV) infection(HBV-liver cirrhosis).Methods Bone mineral density(BMD) was measured by NM-300 sigle-energy X-ray acsorptiometry system for 61 patients with HBV-liver cirrhosis and 30 age-matched healthy controls.Serum levels of calcium regulatory hormones(CRH),1,25-dihydroxycholecalciferol [1,25(OH)_2D_3],parathyroid hormone(PTH),calcitonin(CT),osteocalcin(BGP),interleukin-1?(IL-1?),interleukin-6(IL-6) and tumor-necrosis factor-?(TNF-?),and urine level of crosslaps were measured in these patients and controls.Patients with HBV-liver cirrhosis were divided into two groups,osteoporotic and non-osteoporotic,based on their BMD in the ulna and radius,for comparison.Results BMD of the ulna and radius in patients with HBV-liver cirrhosis were significantly lower than those in controls.Serum levels of 1,25(OH)_2D_3 and BGP in patients with HBV-liver cirrhosis were significantly lower than those in controls,and much lower in osteoporotic group than that in non-osteoporotic one.While urine level of crosslaps increased significantly in patients with HBV-liver cirrhosis than in controls, much more increased in the those with osteoporosis than those without osteoporosis.Serum level of 1,25(OH)_2D_3 correlated with serum levels of BGP and BMD of the ulna and radius.Urine level of crosslaps correlated inversely with BMD of the ulan and radius in osteoporotic patients,but not in non-osteoporotic ones.Serum levels of IL-1?,IL-6 and(TNF-?) and urine level of crosslaps increased significantly in patients with HBV-liver cirrhosis than in controls,as well as increased significantly in those with osteoporosis than in those without osteoporosis.Serum levels of IL-1?,IL-6 and TNF-? and urine level of crosslaps correlated inversely with BMD of the ulna,particularly more significantly in those with osteoporosis than those without osteoporosis.Conclusions Two factors,less osteogenesis and more osteolysis,existed in patients with HBV-liver cirrhosis.Serum level of 1,25(OH)_2D_3 and serum levels of IL-1?,IL-6 and(TNF-?) played an important role in weakened bone formation and in increased bone resorption,respectively.Adequate supplementation of vitamin D_3 and reducing serum levels of IL-1?,IL-6 and TNF-? may be very important for prevention and treatment of hepatic bone disease.

Objective To investigate the gender differences of anal rectal function and depression and/or anxiety in elderly patients with functional constipation (FC).Methods Twenty-seven elder female FC patients (elder female patients group),20 elder male FC patients (elder male FC patients group),28 elder healthy female (elder healthy female group) and 24 elder healthy male (elder healthy male group) were selected.The gender differences and correlation of anal rectal function and psychological factors were compared in elderly patients and control group,by using anorectal manometry and psychological testing methods.Results Compared with elder healthy female group,maximum squeeze pressure (MSP),anorectal pressure decreased in elder healthy male group(P ＜ 0.05 or ＜ 0.01),anal canal overpressure,first sensation volume(FSV),defecating sensation volume(DSV),maximum tolerable volume(MTV) increased in elder female patients group (P＜ 0.01).Compared with elder male healthy group,anal canal excess pressure increased,anorectal pressure decreased (P＜ 0.05),and FSV,DSV,MTV increased in elder male patients group (P ＜ 0.01 or ＜ 0.05).MSP,rectum systolic pressure,anorectal pressure in elder female patients group was lower than that in elder male patients group (P ＜ 0.05 or ＜ 0.01),rectal tube excess pressure and rectal sensation threshold was higher than that in elder male patients group,but there was no significant difference (P ＞ 0.05).RRP,rectum systolic pressure,anorectal pressure in elder female healthy group was lower than that in elder male healthy group (P ＜ 0.01).FSV was higher than that in elder male healthy group (P ＜ 0.01).SAS score and SDS score was higher in elder female patients group was higher than that in elder female healthy group (P＜ 0.01),SAS score and SDS score was higher in elder male patients group was higher than that in elder male healthy group(P＜ 0.05 or ＜ 0.01).SAS score was negatively correlated with MSP,rectum systolic pressure,anorectal pressure(P ＜ 0.01),was positively correlated with FSV(P ＜ 0.05).SDS score was negatively correlated with anorectal pressure (P ＜ 0.01),was positively correlated with FSV,DSV,MTV (P ＜0.01).Conclusions Anorectal dys function and psychological factors are involved in the elderly FC pathogenesy,and the two are related.Elderly female patients exist more severe anxiety and anorectal motility disorders than male patients.

The instrument is com posed of such components as SCM,pressure sensor,electric pump,magnetic valve and sleeve-type gasbag.It can control the hemostatic pressure,hemostatic time and slack time automatically.So the ischemic necrosis can be avoided thoroughly thr ough it.With the small volume,light weight,low power consumption and convenient operation,the instrument is fit for emergency treatment of mass casualties.

Objective To investigate the effects of high-fat diet on pancreatic acinar cells' IP3 expression and CCK-induced amylase release in rats.Methods Male Wistar rats were divided into high-fat diet group and normal diet group,they were fed for 4 weeks.Blood triglycerides,cholesterol,amylase and glucose levels were determined by automatic biochemical analyzer.Pancreatic tissues were taken for histopathological observations.Pancreatic acinar cells were isolated and cultured,and intracellular inositol 1,4,5-trisphosphate (IP3) was detected using a commercial kit.Amylase release rates were measured after CCK-8 stimulation.Results The rats in high-fat diet group appeared hyperlipidemia,vacuolization of acinar cells and the lymphocytes appeared around the acinar cells can be seen on the pancreatic tissue pathology staining.The levels of IP3 in acinar cells of rats fed a high-fat diet were higher than that of normal rats [(31.807 ± 3.448) pmol/106 cells vs (24.632 ± 3.649) pmol/106 cells,t=7.479,P＜0.001];and amylase release rate in these rats'acinar cells were also higher than those of normal rats [when CCK-8=0.01 nmol/L:( 11.056 ±3.369)％ vs (7.354 ± 2.181) ％,t=3.912,P＜0.001;when CCK-8=1 nmol/L:( 13.854 ± 4.087 ) ％ vs (9.432 ±2.477) ％,t=3.939,P＜0.001 ) after CCK-8 stimulation in different concentrations.Additionally,there was a positive co-relationship between acinar cell's IP3 level and amylase release (r=0.896,P＜0.001 ).Conclusion Chronic high-fat diet induces hypersensitivity for pancreatic acinar cells' exocrine function,and IP3 as a signal molecule may play an important role in this process.
