Objective To explore the differential diagnostic value of color-Doppler technique in acute and chronic thrombosis of leg arteries. Methods The two-dimensional and color Doppler ultrasonographic characteristics were analyzed in acute thrombostic event in 80 leg arteries and chronic thrombostic events in 244 leg arteries. And some parameters (history, the vessel wall structures, hemodynamic of inlet and outlet at the lesion) were compared, too. Results There existed a significant difference in history, vessel wall structure and the establishment of collaterals between the acute and chronic groups. And there were also significant difference in maximum blood velocity proximal and distal to the lesion and proximal resistant index between two groups(P

ObjectiveTo observe the effect of sport walking on heart and lungs functions in old women.MethodsForty-two old women aged from 60 to 69 had sport walking for 4 months; the speed and intensity were controlled according to their heart rate respectively. The indexes of respiration, circulation and rheoencephalography were measured before and after exercise.ResultsAfter exercise, blood-pumping function of heart improved obviously, stroke volume increased from (65.22±11.41)ml to (72.10± 10.78)ml, ejection fraction increased from (60.10±5.03)% to (68.78±6.25)%, while heart rate declined from (77.45±8.69) times/min to (7.89±8.21)times/min, capacity increased from (2.86±0.36)L to (3.34±0.53)L, and maximal voluntary ventilation for every minute increased from (96.14± 15.21)L to (114.02±16.01)L, significantly different compared with that before treatment ( P<0.01). The fluid time of rheoencephalography reduced from (0.171±0.058)s to (0.128±0.049)s ( P<0.01).ConclusionSport walking under proper intensity can improve the function of respiration and circulation system in old women, so it is a good way to keep health for the elders.

Objective To analyze the clinical speciality of invasive fungal infection(IFI)and provide doctors with clinical evidence for early anti-fungal therapy.Method One hundred and thirty-seven patients with 91 male and 46 female,who suffered from invasive fungal infection in ICU from January.1,2000 to June 30, 2006,were enrolled in this study.The age ranged from 17 to 82 years old.Out of 137 patients with IFI,the percentage of albicans candida,glabirate candida,tropicalis candida and parapsilosis candida were 47.4%, 26.3%,20.4% and 3.6%,reseparately.The sputum,urine,blood and other drainages were collected to perform the fungal examination after three days of admission every three days.Results Of 137 patients,42 of them were complicated with hemorrhage,53 patients with IFI developed candida anthema in the chest,abdomen and extremity.,49 patients suffering from IFI had organ dysfunction.The chest image revealed that infiltration caused by IFI especially occurred in apex of lung in some patients.The pathogen analysis displayed that albicans candidiasis easily developed candida anthema,glabirate candidiasis frequently resulted in organ dysfunction,and tropicalis candida led to hemorrhage in some organs.Conclusions The clinical specialty,of IFI caused by candida included hemorrhage,candida anthema,organ dysfunction,and infiltration in apex of lung.

The basic theory of high power green laser equipment for prostate hyperplasia therapy and the components of the system developed are introduced. Considering the requirements of the clinical therapy, the working process of the high power green laser apparatus are designed and the laser with stable output at 120 W is achieved. The controlling hardware and application software are developed, and the safety step is designed. The high power green laser apparatus manufactured with characteristics of stable output, multifunctional and friendly interface provides a choices of prostate hyperplasia therapy for using nationalization instrument.

Objective Therapeutic hypothermia has become a standard neuroprotective treatment in term newborn infants following perinatal asphyxia,but active cooling with whole body surface or head cooling is both complex and expensive.The clinical feasibility of passive cooling in treatment of full term infants with severe asphyxia was investigated.Methods Thirty-two severe asphyxiated term newborns treated with hypothermia were analyzed,who were randomly divided into 2 groups:passive cooling group(n =17) and active cooling group(n =15).Active cooling group adopted MTRE ALLONTM-thermo regulatory systems,passive cooling group using natural cooling method.Hypothermia treatment time was 72 hours.At the end of treatment,the clinical manifestations,biochemical parameters and clinical efficacy of infants between the 2 groups were compared.Results During treatment all infants had no cardiac arrhythmia,hypoglycemia,sustained metabolic acidosis,blood-borne infections,local cold injury or bleeding.Infants in passive cooling group had a relatively wide range of rectal temperature fluctuations[average (33.47-0.71) ℃] and infants in active cooling group had a relatively narrow range of rectal temperature fluctuations[average (33.66 ± 0.29) ℃],but there was no statistically significant difference in their mean rectal temperature(t =1.941,P =0.055).One patient died in active cooling group,but there were no significant differences in suckling age,length of hospital stay,neonatal behavioral neurological assessment score,abnormal cranial ultrasound and MRI between the survivors of the two groups(all P ＞0.05).Conclusions In NICU,environmental temperature is relatively stable,passive cooling for asphyxiated newborns appears to be feasible for maintenance of hypothermia with a lower risk of adverse reactions.

Objective To establish a simple and sensitive method for the determination of serum copper by spectrophotometry.Methods Nitro-PAPS was used as a coloring agent for serum copper in the presence of surfactants Tween-80 and Triton X-100 and the formed complex was measured by spectrophotometry.Results The maximum absorption wavelength of the complex was 570 nm and the molar absorption coefficient was 7.95?10~4 L/(mol?cm).The lineafity of the method was up to 63.0 ?mol/L and the recoveries ranged from 98.6% to 103.1%.The within-run and between-run CVs were 2.1%-3.3% and 2.7%-3.8%.The method(Y)was compared with an AAS method(X)and a correlation of Y=1.01X -0.27(r=0.998 2)was obtained.A reference interval(x~-?2s)determined with this method on 68 individuals was 9.7-24.1 ?moL/L.Conclusions A simple and sensitive method for serum copper has been established.It may used for the analysis of serum copper in clinical laboratories.

Objective To investigate the nutritional risks, undernutrition, and nutritional support among inpatients in tertiary hospitals in Tianjin using Nutritional Risk Screening 2002 (NRS2002). Methods Inpatients in six departments in two tertiary hospitals in Tianjin (Tianjin Nankai Hospital and Tianjin Chest Hospital ) were consecutively enrolled from March 2005 to March 2006. Their nutritional risks were screened using NRS 2002, and the nutritional support was investigated. Results A total of 1200 inpatients received nutritional screening, and 93.0% of them underwent NRS 2002 scoring. The prevalence of undernutrition was 9. 8% and the prevalence of nutritional risk was 42. 8%. Of these patients, 241 patients (46.4%) with NRS2002≥3 received nutrition support, and 244 patients (35.9%) with NRS2002 ＜3 received nutritional support Conclusions NRS2002 is suitable for nutritional risk screening among inpatients. Inpatients usually have nutritional risks or undernutrition. However, physicians at different levels in different regions have different awareness of such risks or conditions, and the clinical application of nutritional supports sometimes are inappropriate.

Objective:To search the release in vitro of new MU-AN ophthalmic gel consist of ganciclovir instead of aciclovir is whether better than the Old. Methods:Using the content of ganciclovir and acyclovir as the index, taking the second oar method ( in Ch. P 2010), drug release in vitro test was investigated. Results:The character of drug release of new MU-AN ophthalmic gel was e-qual to the old, the rate of drug release was similar, The amount of drug release was the same. Both drugs met the requirements of clin-ical medication. The character corneal permeability of new MU-AN ophthalmic gel was better than the old. Gel matrix had no influ-ences on drug release, drug would be bring treatment effect after the way that it was released quickly then was dissolved in tear. Con-clusion:The drug release characteristics consistent with ophthalmic preparation requirements. The character of drug release of new MU-AN ophthalmic gel consist of ganciclovir instead of aciclovir is equal to the old, the time administer drug and interval time is gener-ally scientific, reasonable and feasible, providing the basis for the pharmacodynamics , toxicology and clinical study in the next step.
