Background and purpose:There is an increasing of breast diseases every year. It is important for us to detect the tumor characteristic and to establish the diagnosis of breast diseases through their clinical manifestation and pathology.Methods:A retrospective analysis of 864 cases of breast diseases after surgical operation,was made in our hospital, from 2000 to 2006.Results:85.7% of 864 cases were fibro benign diseases, and most of them were fibro cystic hyperplasia and fibroadenoma of breast.Malignant disease was found 123 cases, and most of them were invasive ductal carcinoma, then medullary carcinoma and early infiltrating carcinoma.It is significant that the youngest age from 30 years old and the incidence rate increased with the age.Conclusions:It is very important to promate the diagnosis rate of breast carcinoma by early prevention and treatment to screen breast diseases and monitor high risk population in time.

Objective To investigate the role of resting pulm on ary function (FEV 1,FVC,VC) and diffusing capacity (D LCO) on exercise limitation in patients with chronic obstructive pulmonary disease (COPD).Methods During the period of 2002-04~12 the results of resting pulmonary function test which were and diffusing capacity test performed on 26 subjects with stable COPD were reviewed.The symptom-limited maximum exercise (S LME) were performed.Dyspnea index (DI) and oxygen consumption (V? O 2/kg) were determined with a metabolic cart during exercise.Borg Scale s (BS) was used for counting degree of exertional dyspnea which appeared during exercise.At the end of SLME,arterial blood gas analysis was performed to determi ne PaO 2max,PaCO 2max and Phmax at that time.Results In stepwise multiple regression analysis,the variables significantly contributing to V?O 2max/kg were D LCO % and FEV 1/VC.Conclusion Lung function and diffusing capacity can be importan t determinants of exercise capacity in COPD.

Objective To introduce three new methods for measuring breast volume. Methods The breast volume was measured and the 3D image yielded with a special software or calculated with two mathematical formulas, according to its base, horizontal and saggital sections. Results The average deviations of these protocols were less than 10 % of the actual sizes in our investigation. Conclusion The computer aided measurement for the volume of the breast is an accurate and reliable method and can be used in the designs for augmentation and reduction of mammaplasty.

Objective To investigate the distribution of the mini mental status examination in the elderly Methods Totally 3 776 residents aged 55 years or over serving as samples in the urban and rural areas of Lhasa city, from August to December in 2001 were studied A residential area and a door to door general sampling procedures were used in this study, respectively Mini mental status examination (MMSE) and a activity of daily living scale (ADL) were used as screening methods for dementia Results The distribution of lower scores in such examination in middle elderly people, in Lhasa city was 7 2%, in which, males were 9 3% and femals, 6 3% Conclusion The results of lower scores in the mini mental status examination were similar to those reporting from inland cities, but there appear some what differences in distributions of ages, educational levels and sexes from Tibetan, which may be due to their special location and living habits

Objective:To investigate the effect of Yishen Bunao Tablet on Alzheimer's Disease(AD).Methods:91 cases of AD were randomly divided into a treatment group(n=46)treated with Yishen Bunao Tablet and a control group(n=45)treated with huperzine A. Their clinical therapeutic effects,changes of superoxide dismutase(SOD)activity,malondialdehyde(MDA)and nitric oxide(NO) contents before and after treatment were determined.Results:There was no significant difference between the two groups in the total therapeutic effect;After treatment,the scores for language comprehend and order obey in the treatment group increased significantly(P0.05).SOD activity increased significantly,and contents of MDA and NO decreased significantly in the control group(P

Objective To investigate the distribution of traditional Chinese medicine (TCM) syndrome types of functional dyspepsia (FD) in Guangzhou, and to explore their correlation with some factors such as residence time in Guangzhou, gender, age, and Helicobacter pylori (Hp) infection. Methods A total of 326 cases of FD patients from Guangzhou were investigated. Database of the related clinical data was built and analyzed. Results The commonly-seen TCM syndrome types of FD patients in Guangzhou were spleen-deficiency and qi stagnation, disharmony of liver and stomach, dampness-heat of spleen and stomach, deficiency-cold in spleen and stomach, and concurrence of cold and heat, accounting for 41.71%, 26.07%, 11.96%, 11.04% and 9.20%, respectively. There were significant differences among the TCM syndromes(P < 0.05). The differences of average age of onset, residence time in Guangzhou, FD subtypes and Hp infection were significant among each syndrome type (P < 0.05). Conclusion The distribution of TCM syndrome types of FD in Guangzhou is dominated by spleen-deficiency and qi stagnation, and the syndrome types are correlated with residence time in Guangzhou, gender, average age of onset, FD subtypes, and Hp infection.

Objective To investigate the curative effect of methotrexate in treating systemic lupus erythema-tosus(SLE). Methods The chosen outpatients were divided into 2 groups,group A(28 cases) :MTX combined with small dosage of prednisone (prednlsone 10mg/d) ; group B (20 cuses) : medium dosage of prednisone (prednisone 30rag/d). Observation includes SLE disease activity index(SLEDAI) ,relapse while dosage of prednisone was reduced to small amount and drug side effects. Results The SLEDAI score of group A was reduced from (9.4±2.1) to (4.1±0.9) ,and group B from (8.6±2.5) to (4.0±1.0). Compared the result of before and after treatment be-twcen the two groups, the curative effect is obvious (P<0.01). However, there was no significant difference of efficacy between the two groups(P>0.25). While dosage of prednisone was reduced to 10mg/d ,there were 8 cases of relapse in group B,and only 3 cases in group A during the entire observation period. The difference is significant (P<0.025). The side effect of group A is gastrointestinal reaction and for B is mainly the cushing syndrome. Conclusion MTX is an effective treatment fw the light and medium activity SLE,and can reduce the dose of prednisone, prevent long-term using large dose of prednisone which will cause side effect.

ObjectiveTo investigate the effects of pre-infusion of hypertonic sodium chloride hydroxyethyl starch 40(HH40)injection in prevention for transurethral electroresection of the prostate syndrome(Tuns).MethodsSixty patients with benign prostate hyperplasia(ASA)grades Ⅱ toⅢwere recruited in the study and randomly divided into two groups,one injected intravenously with HH40 at dose of 5 ml/kg by drip after sursical operation a8 experiment and the other injcoted with the same volume of Ringer's solution as control Mcan arterial pressure,heart rate,saturation of blood oxygen(SaO2)and central venous pressure were monitored for all the patients.In addition.serum concentrations of sodium,potassium,chloride and serum osmolality were determined before(T0)and 30 min(T30)and 60 min(T60) after operation,respectively,as well as pH valRe and partial pressure of carbon dioxide(PgCO2)in the gastric mucosa were determined by a Tonocap monitor.Occurrence of TURS and use of atropine,ephedrine and rinse solution were documented.Resuits TURS occurred in four patients in the eontrol group during surgical operation,whereas uo TUns occurred in experimental group.Serum sodium concentration was (126.5±13.3)mmoL/L at T60 in control group,significantly lower than that in experimental group(P＜0.05),while intragastric pH value and PgC02 level were(7.26±0.04)and(54±9)mm Hg[(7.2±1.2)kPa],respectively in controls,significantly higher than those in experimental group(P＜0.05).ConclusionsPre-infusion with HH 40 can improve tissue perfusion and prevent effectively from TURS in patients with transurethral electroresection of the prostate.

The effects of thy rotropin-releasing hormone (TRH) on survival time, hemodynamics, acid-base balance and subcellular structure of liver cells in canine severe hemorrhagic shock were studied. The results showed that: (1) TRH significantly elevated and maintained mean arterial pressure (MAP) of dogs during shock (MAP was 13.99 ? 0.62 kPa at 4 h after treatment vs 5.09? 105 kPa in control); (2) TRH significantly prolonged the survival time of dogs (alive/total = 4/5 vs 1/5); (3) TRH effectively maintained acid-base balance; and (4) TRH maintained the integrity of subcellular structure of the liver cells. These results suggest that TRH may reverse severe hemorrhagic shock.
