CD5+ B cells are derived from early stage precursors independently on bone marrow. It is an important subtype of B cells. Abnormalities of number and function of CD5+ B cells are found in several kinds of autoimmune diseases and B lymphocyte malignancies. Recently,the abnormalities are also found in AIDS,hepatitis, schizophrenia and the regeneration of liver cells, which indicates that CD5+ B cell may have extensively clinical significance.

Objective To investigate the etiology, pathology, diagnosis and management of patients with fat necrosis of breast (FNB). Method The clinical data of 50 cases of FNB confirmed pathologically in our hospital from 1966 to 2001 were analyzed retrospectively. Results All the patients in this series were females with the average age of 32.5 years and 56% of the patients over 30 years. The main clinical feature was breast lump and some of the patients had a trauma history. 48 patients were treated surgically and other 2 got an accurate diagnosis by biopsy and were treated by non operative therapy. Conclusions FNB is easily misdiagnosed and difficult to be differentiated from breast cancer, thus the surgery or needle biopsy is recommended.

Objective To investigate the diagnostic and theraputic problems in patients with smooth muscle tumors of the duodenum.Method The clinical data from 7 cases smooth muscle tumors were analyzed retrospectively which were treated surgically and confirmed pathologically in our hospital from 1987 to 2001.Results Of all the cases,4 had a leiomyoma in the duodenum and 3 leiomysarcoma.This disease is lack of pathognomonic sign and difficult for early diagnosis.All the cases were treated surgically and got good results.Conclusions Upper gastrointestinal bleeding is common in patients with this disease.Upper gastrointestinal tract examination and gastrduodenoscopy and CT scan are the main methods for diagnosis.Operation is the best choice for treatment.

Dystonia is common in children with cerebral palsy. It can cause motor dysfunction, and is frequently associated with altered speech articulation, abnormal swallowing, and excessive drooling. Although trihexyphenidyl (Artane) is an anticholinergic agent with a long history of use in the management of dystonia in adults, information is limited regarding the use of trihexyphenidyl in children. This study reviewed the clinical experience of the use of trihexyphenidyl in children with cerebral palsy for dystonia, with special emphasis on benefits and tolerability.

Objective To summarize the ruptured types, operational ways and therapy effect for rupture of aortic sinus aneurysm.Methods The operational cured 55 cases with aneurysm of aortic sinus were retrospectively analysed.Results There were 46 cases of right aortic sinus aneurysm, 45 cases among them rupture was peretrated into right ventricle, one rupture was peretrated into right atrium;there were null aneurysm of aortic sinus, 5 cases among them ruptured into right atrium, 2 cases ruptured into right ventricle; 2 cases of left aneurysm of aortic sinus, ruptured into left ventricular. There were 24 cases with ventricular septal defect, 32 cases with aortic valvular imcompetence, 6 cases with other diseases, 8 cases complicated with infective endocarditis. All cases underwent operational treatment, one patient who had severe left heart failure and huge left ventricle before operation died from refractory arrhythemia after operation, another who had severe infective endocarditis,and patients with cardic function degree Ⅳ were died from low cardic output syndrome, others were better.Conclusions The right aneurysm of aortic sinus were the most types, and it always ruptured into right ventricle; It suggests that it is important for aneurysm of aortic sinus should be operated as early as possible in order to avoid losing the chance of operation, particular in the patients complicated with infective endocarditis .

Objective To investigate the pefinatal infant brain damage in the blcod of neuron specific enolase and long-term changes in the development of nervous system disordem related to the neonatal brain injury prognosis timely predictions for the early intervention and provide a theoretical basis.Methods 40 cases of periatal brain injury in newborns were selected for the study.20 patients over the same period of normal newborns assigned to the control groups.both groups in the 72 hours after birth within the collected blood samples submitted preservation of the neuronspecific enolase enzyme,and rely follow-up of the two groups,so as to cover Gesell development scale statistical analysis of neuron specific enolase and perinatal brain damage in children with long-term development of nervous system disorder relevant.Results Brain injury group blood neurompeeifie enolase concentrations were higher:15-month-old brain-injury group scale evaluation of sale to group health suspicious after three clays of Mood neuronspecific enolase concentrations significantly higher to the development of the normal group.Conclusion Neuronspecific enolase may change as early diagnosis of perinatal brain injury,as well aft the main indicators of the long-term prognosis.

Objectives:To explore the change of peripheral blood CD5+B cells and its association with indexes of liver function in patients with hepatitis B.Methods:Change of peripheral blood CD5+B cells was detected immunohistochemically.The indexes of liver function were examined by HITAI 7170 automatic analyzer.Results:There were no significant differences in the percentage of peripheral blood CD5+B cells between patients with acute hepatitis B and normal controls.With the severity development of hepatitis B from chronic hepatitis to cirrhosis,the percentage of peripheral blood CD5+B cells is positively correlated with the increase of ALT，AST，GGT，TB and ALB.Conclusions:A large number of CD5+B cells are activated in patients with chronic hepatitis B,heavy chronic hepatitis or cirrhosis.The percentage of peripheral blood CD5+B cells increases concomitantly with the liver impairment.

Objective To investigate the urodynamic measurements in later pregnant women with urinary incontinence. Methods According to the symptoms, a total of 63 volunteers in later pregnancy were divided into two groups including urinary incontinence group and no symptom group. Fourteen women who were married but not delivered were included in control group. Urodynamic study was performed on all women. Results The occurrence rate of urinary incontinence in later pregnancy was 26.98%. The valsalva leak point pressure only occurred on two pregnant women were 50 cmH2O and 67 cmH2O respectively. Compared with the no symptom group, the maximum urethral closure pressure[(83.69±42.55)mmHg vs(108.09±34.95)mmHg, P＜0.05])and the functional urethral length [(30.45±8.42)mm vs (37.60±18.45)mm ,P＜0.05]of urinary incontinence group were decreased obviously. Conclusions The main reason of urinary incontinence in pregnancy was that the maximum urethral closure pressure could not sufficiently increase to compensate for the progressive increase in bladder pressure during pregnancy and functional urethral length could not correspondingly increase along with the pregnancy.

BACKGROUND:It is important for the aged population to improve the locomotor activity, maintain a high-level quality of life, and delay the loss of self-care ability.
OBJECTIVE:To analyze the physique properties and influencing factors of the aged population in some areas of Jiangsu province, and to investigate the rule of physiological aging process.
METHODS:In nine test sites of three cities (Nanjing, Yanhceng and Changzhou) of Jiangsu Province, 520 effective samples were col ected and composed of 42.9%males and 57.1%females. We tested the reliability and validity of inspected questionnaire on the aged physique and sports, and then adopted the questionnaire to get general demographic information about their gender, age, education, used occupation, income and physical exercise. At the same time, physical tests were performed (including nine projects such as body shape, physical function, body quality).
RESULTS AND CONCLUSION: ① More than half of the surveyed aged have reached overweight level according to their body mass index, while only a few have normal body mass index, especial y the females. ② Most of the surveyed aged have abnormal blood pressure, and a large number of the aged are in moderate to severe hypertension. ③ There is a gradual y reduction in upper and lower limbs muscle strength, balance ability and walking ability along the aging, a substantial drop is found after 75 years old. There is no obvious difference between male group and female group expect grip strength. ④ Physical exercise can delay the degenerative change in muscle strength and balance ability of the aged. Education has great influence on the physical quality and used occupation influences blood pressure. Having a retired wage also has significant effects on physical quality index and blood pressure, but no influence is found in body shape.
