Objective:To investigate the eating disorder and mood among students of a female university in Beijing.Methods:352 female students from a same-sex college in Beijing,between the age of 17-25 years were in- vestigated by Eating Disorder Inventory(EDI)and Profile of Mood States-Short Form(POMS-SF).Their weight and height were also collected for calculating for their body mass index(BMI).Results:Female university students showed serious tendency of eating disorder.The negative attitudes to body and body satisfaction were serious among normal BMI female university students.The behaviors and attitudes to eating disorders among the students of fresh-woman and senior were significantly higher than other grades(x~2=17.94,P

Objective To study the effects of 2,2',4,4'-tetrabromodiphenyl ethers(PBDE-47)single exposed and combined with 2,2',4,4',5,5'-hexachlorobiphenyl(PCB153)on learning and memory ability and the uhrastrncture of hippocampal CA1 region in rats.Methods Neonatal SD rats(CL grade)were randomly divided into groups,9 male and 9 female in each,then were exposed to single PBDE-47 at doses of 1,5,10 mg/kg and combined with PCB153 at dose of 5 mg/kg,through gavage for one time. Soya oil was used as the solvent control.The learning and memory ability and ultrastructure of neurons in hippocampal CA1 region were examined respectively 2 months after treatment.Results In the low dose groups(1 mg/kg PBDE-47 and 1 mg/kg PBDE-47+ 5 mg/kg PCB153 treated group),the ultrastructure of neurons in hippocampal CA1 region were as normal as that in the control group.As the dose increasing,in 5 mg/kg PBDE-47 group,the endoplasmic reticulum appeared swelling,expansion and degranulation.In 5 mg/kg PBDE-47 plus 5 mg/kg PCB153 group,the mitochondria appeared swelling,the ridge ruptured,the periplast puffed,and then the cytoplasm condensed.In the high dose groups(10 mg/kg PBDE-47 group and 10 mg/kg PBDE-47 plus 5 mg/kg PCB153 group),the neurons showed acutely denatured,the periplast puffed,the cell organelle dissolved and the mitochondria vacuolizated.The interaction between PBDE-47 and PCB153 on the latency period and the general pathway was presented in place navigation test(P

Objective Through the comparative study of the acute toxic effects of PM2.5 in nickel-contaminated area in rats to explore the possible mechanism of acute toxicity of PM2.5.Methods A nickel-contaminated area and a control area were selected,the air quality of the two areas was monitored and the concentration of nickel in the collected PM2.5 was determined. Forty two male Wistar rats(SPF Grade)were randomly divided into three groups,including one saline control group and two experimental groups,the nickel-polluted group and the non-polluted group,in each.There were three subgroups.PM2.5 were administered to rats by intratraeheal instillation at doses of 1.6 mg/kg,8.0 mg/kg and 40.0 mg/kg respectively.The rats were sacrificed 24 hours after treatment and the brochoalveolar tavage fluid(BALF)were collected,the phagocytic function of alveola macrophages of rats were tested.Results There was no significant difference between the level of environmental quality in the two areas,the concentration of Ni in PM2.5 in the nickel-polluted area was 48.75 times of that in the non-polluted control area.The phagocytic function of alveola macrophages of rats in the experimental groups decreased significantly(P

Objective To investigate the clinical manifestation of bacterial urinary tract infections among old patients with diabetes in recent seven years.Methods In this retrospective study,contrast analysis of clinical features was per- formed on urinary tract infections in old patients between 56 cases with diabetes and 56 cases without it diagnosed during 1998 to 2005.measuring fasting blood glucose,2 hour blood glucose,plasma albumin,24-hour microalbuminuria. Results Incidences of diabetic nephropathy,diabetic retinopathy,neuropathic bladder in observed group are signifi- cantly higher than control group.FBG、2hPBG、24-hour microalbuminuria are significantly higher than control group and plasma albumin is lower than control group.Conclusion The urinary tract infection in old patients with diabetes is associated with fasting blood glucose concentration,complication,gender,disease period and ages,etc.

Objective To study the role of transversus abdominis in lumbar spine stability,and to find a way to assess the abdominal muscles function.Methods 15 healthy subjects performed rapid arm flexion,abduction,and exten- sion.Electromyographic(EMG)activity of transversus abdominis,rectus abdominis,obliquus externus abdominis, obliquus internus abdominis and deltoid was evaluated with surface electrodes,latency between onset of the abdominal muscles and of the deltoid was calculated.Results The transversus abdominis invariably contracted before the deltoid and the other abdominal muscles,except the obliquus internus abdominis during arm extension.Conclusion(1)It's an effective way that latency between onset of abdominal muscles and of deltoid is used to assess the abdominal muscles function with arm movement as a factor of influencing the balance of spine.(2)Transversus abdominis,as deeper mus- cles acting earlier with all movements play an important role in maintaining the stability of lumbar spine.

Objective To observe the effectiveness of Antithymocyte globulin/antilymphocyte globulin(ATG/ALG)in the treatment of nonsevere aplastie anemia(NSAA)patients who didn't respond to cyclosporine A(CsA)or relapsed and review the literature.Methods We administered ATG/ALG to 5 NSAA patients who relapsed or showed no re- sponse after CsA therapy.Results 3 patients were cured,2 patients improved,4 patients became transfusion inde- pendent in 90 days,none relapsed or progressed to clonal disease.Conclusion Those NSAA patients who relapsed or showed no response after CsA therapy should be asministered ATG/ALG,so as to reduce transfusion complications and prevent sustained immune attack to the bone marrow.

Objective The aim of the study is to approach the clinical significance of the change of ST segments after di- rect percutaneous transcoronary angioplasty(PTCA) combined with Lipo-PGE_1 in treating Acute Myocardial Infarction (AMI).Methods The change of the ST segments on EKG of 76 patients with AMI are observed in 30 minutes after un- derwent direct PICA combined with Lipo-PGE_1,and the relations are analyzed that are prospectively to their therapy effect,the degree of injured cardiac muscle,the cardial functions,and the prognosis.Results The patients who treated with the PCTA combined with Lipo-PGE_1 ST segments on EKG 30 minutes after operations reduced significantly,cardiac muscle is injured lowly,their cardial functions are better.Conclusion The change of ST segments after direct percutane- ous transcoronary angioplasty (PTCA) combined with Lipo-PGE_1 in treating acute myocardial infarction is one of the guide line to estimate the perfnsion of cardiac muscle,and to estimate prognosis farther.

Objective To investigate the correlation between renal biopsy pathology(RBP) and Renal intertitial fibrosis (RIF).Methods 112 cases of RIF patients were collected in our hospital who had done RBP examination and were di- vided into four groups based on RIF degree.Results 45 cases in light group,22 cases in moderate group,15 cases in se- vere group and 30 cases in control group.With different RIF degree,renal pathology were different.Conclusion IgAN、 LN、FSGS were much more in moderate and severe RIF group compared with those of other groups,MSPGN were seen in any RIF degree groups.

Objective To evaluate the value of ERCP in treating hepatocellular carcinoma complicated with tumor thrombi in bile duct.Methods To analyze retrospectively the results of 15 cases of hepatocellular carcinoma with tumor thrombi in the bile duct including ERBD 8 cases and ENBD 7cases,EMBE after ENBD 4 cases, EST with clearance of tumor thrombi and cytological brush 12 cases, ERCP conjugated with other compositive treatments 9 cases.Results The common feature of cholangiography is filling defect in the bile duct as the so called "tennis bat" sign and "flocculation" sign, 13 cases have got drainage successfully after ERCP with the effective rate 86 7%, Satisfactory results were obtained in patients received ERCP conjugated with other compositive treatments.Conclusion ERCP is very important treatment of hepatocellular carcinoma with tumor thrombi in the bile duct; the "tennis bat" sign and "flocculation" sign were the very important evidences of tumor thrombi in the bile duct. If combined with other compositive treatment such as surgery and TAE, ERCP is very effective treatment for the releasing symptoms, improving living quality and prolonging life span in these patients, even in some patients radical cure could be obtained.
