Advanced schistosomiasis,encompassing a wide range of pathologic entities and multi-complications,poses a se-rious threat on the patients'health. Through comprehensive analysis and evaluation on related aspects regarding clinical classifi-cation,main methods of auxiliary examination and treatment(including types of surgical procedure)of advanced schistosomia-sis,we think that the individual based multidisciplinary comprehensive treatment according to varying conditions of patients is the most optimal treatment mode of advanced schistosomiasis. It is further proposed that multidisciplinary collaborative diagnosis and treatment system should be undoubtedly established,multidisciplinary case discussions be regularly organized,and treat-ment expert teams be stably formed,in order to significantly improve the level of diagnosis and treatment of advanced schistoso-miasis,so as to reduce the misdiagnosis and improve the therapeutic effect in advanced schistosomiasis control.

Objective To investigate the effect of nursing rescue process on traffic accident aid to orthopedic patients . Methods Sixty patients with bone injuries from traffic accidents during April to December 2013 were set as control group , in which the traditional aid process was used for rescue, and another 60 patients during January to June 2014 as experiment group, in which the nursing aid process was applied. The two groups were compared in terms of rescue time and effectiveness. Result The rescue time in the experiment group was significantly shorter and the first aid effectiveness was also better than those in control group (P<0.01). Conclusion By nursing aid process, the personnel can be optimized to avoid chaos during the rescue and meanwhile the time for rescue is shortened, which can contribute the increased success rate.

BACKGROUND: Alzheimer disease (AD) and vascular dementia (VD),the two major types of dementia in old age, differ from each other in pathological mechanism, treatment and prognosis. Up to now, no effective therapeutic method for AD is available, but VD can be treated effectively so that patients' quality of life can be improved.OBJECTIVE: To investigate the clinical features of brain electrical activity mapping (BEAM) and brain evoked potentials (BEP) between AD and VD patients.DESIGN: Retrospective analysis based on AD and VD patients.SETTING: Neurological Department, the First Clinical Medical College of Harbin Medical University.PARTICIPANTS: All inpatients and discharged patients were selected filiated to Harbin Medical University from December 1996 to December 2000. The history was provided by the patients themselves or their relatives who lived together with them. Nine cases of AD and fourteen cases of VD were diagnosed according to the diagnostic standard for AD and VD set by the National Institute of Neurological and Communicative Disorder and Stroke-the Alzheimer disease and Related Disorder Association, and Chinese Classification and Diagnostic Criteria of Mental Disease (4th edition). According to the clinical rating standard, the patients had mild or moderate degree of dementia.METHODS: AD and VD patients were analyzed with retrospective analynitive functions, including long-term and short-term memory, calculation,comprehension, abstract thinking, dyschronism and disorientation; c. emotional reaction, including depression, anxiety, fear, euphoria, compulsive laughing and crying; d personality alteration, including indifference,optimally were collected from the abnormal segment signals. After calculation, 4 frequency band powers of θ,δ, α and β of the total power of 1-30 N1, P2, N2 and P3 and the waves of P2 and P3 were measured. Comparison between the two groups and rate comparison were made with t-test and χ2 test, respectively.ease, cognitive functions and noncognitive functions between AD patients RESULTS: Data of 9 AD and 14 VD patients as well as 15 normal old cognitive functions and noncognitive functions between AD patients and VD patients: The onset of AD was slow, but that of VD was abrupt. Cognitive functions of AD patients were decreased, including memory decline,calculation decrement, abstract thinking disorder, dyschronism and disorientation. The cognitive functions of VD group were characterized by partial decrement and intermittent ladderlike aggravation. Memory decline and calculation ability decrease were the main characteristics, but other cognitive dysfunctions could not be observed as much as in AD. The patients of AD group often had depression as the most common emotional disorder.Personality alteration took initiative decrement as the most common one,whereas emotional disorder in the patients of VD group was presented by compulsive crying and laughing. One patient seldom had more than two and VD patients: BEAM of 7 AD patients was characterized by the power of θ frequency band of the whole head increased. The level of increase was consistent with the level of dementia (score of MMSE). At the same time,the power of α and β frequency bands declined, and the power of δ increased later, the left side (F3) was significantly higher than the right side AD and VD patients: The changes of BEP in the two group patients had poorly differentiated waves, with lower P300 wave and obviously delayed latent period. The abnormality degree of patients in AD group was more obvious than that in VD group.with memory decline and calculation ability decrease as the main characteristics in VD patients. The noncognitive functions of AD patients were more aftients were presented as the increased power of the whole head in the former ones and the increased power of θ frequency band in the latter ones. The changes were coincident with the severity of dementia in AD, but not in VD.effect of the former one was greater than that of the latter one.

Objective To investigate the association of the gene polymorphism of endothelial nitric-oxide synthase(eNOS) with pregnancy induced hypertension(PIH). Methods Sixty-six gravidas with PIH and 91 normal pregnant women(control) in the third trimester were investigated. The G894T mutation at exon 7 of the endothelial nitric-oxide synthase gene was studied by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results The frequencies of eNOS GG, GT and TT genotypes were 62.1%, 34.8% and 3.1% in PIH group and (79.1%,) 20.9% and 0.0% in control group, respectively (P0.05). Conclusions The variant (G-T) of 894 polymorphism site of eNOS is associated with the genesis of PIH, but not related to the severity of PIH. T allele may be a susceptible gene to PIH.

Objective To investigate the imaging diagnostic value of the early avascular necrosis of the femoral head(ANFH) in adult.Methods There were 25 cases (34 hips) with early ANFH diagnosed by imaging and clinical data.Radiography,CT and MRI findings of ANFH were analysed comparatively.Results In the 34 ANFH included stage Ⅰ 13 hips,stage Ⅱ 21 hips.The diagnostic accurary was 32.4% for X-ray,61.8% for CT and 100% for MRI.Conclusion MRI is better than the other technique in early finding the lesions of ANFH,and the diagnostic sensitivity and accuracy of MRI are higher than that of CT and X-ray.

Microcell mediated chromosome transfer (MMCT) is a challenging technique for introducing exogenous chromosomes into interested mammalian cells. Combined with the somatic cell nuclear transfer technique, MMCT has been employed for producing transchromosomic animals of medical and agricultural value. Producing high quality of microcells is a key step in the success of MMCT. Eamamined by fluorescin staining and Giemsa staining, 0.2 mg/L colcemid was considered suitable for inducing high percentage of micronuclei in A9 (neo12) cells, without causing death of a mass of cells. Microcells were produced by centrifugation of micronucleated A9 (neo12) cells in Percoll density gradient containing 20 mg/L Cytochalasin B at 39 000 g. The resulting mixture of microcells, whole cells, karyoplasts and cytoplast fragments was filtered through 8 μm and 5 μm size membrane pores sequentially to obtain pure preparation of microcells. Microcells were then characterized by Giemsa staining and microcell PCR was first applied for examination of the quality of microcell preparation. The result showed that microcells containing our interest chromosomes-human chromosome 12 were equally distributed in the preparation, the preparation was suitable for use in generation of transchromosomic animals.

Objective To summarize the age-related changes and the risk factors of renal tubular function in the elderly male cases.Methods Totally 229 cases without chronic kidney disease were divided into two groups:group aged ＜80 years and group aged ≥80 years.We measured the urine routine,serum creatine,serum urea,urine β2-microglobin (β2-MG),urine α1-microglobin (α1-MG)and calculated the eGFR based on Cockcroft-Gault equation.Logistic regression was used to analyze the risk factors which may accelerate the progression of the renal tubular impairment.Results The average age of 229 cases was (76±10)years.There were 142 cases in the group of ＜80 years old and 87 cases in the group of ≥80 years old.The level of eGFR in the group of ≥80 years old was (55.0±12.7) ml/min,which was lower than that of the group of ＜ 80 years old (80.3 ± 18.0 ml/min) (t =9.882,P＜0.01).The level of urine SG was decreased in the group of ≥80 years old versus in the group of ＜80 years old(1.016±0.006 vs.1.013±0.006).The value changes of urine pH,urine β2-MG and urine α1-MG were of statistical differences between the two groups [(6.2±0.8) vs.(6.6±0.8),(0.96±1.02)mg/L vs.(2.08 ±3.56)mg/L,(6.67±3.57) mg/L vs.(8.71±6.59)mg/L].The correlation analysis showed that age correlated negatively with eGFR and urine SG(r =-0.692and r=-0.280,both P＜0.01)and positively with urine pH(r=0.255),urine β2 MG(r=0.262),urine α1-MG(r=0.228)(all P＜0.01).The Logistic regression analysis showed that coronary heart disease was an independent risk factor for the progression of renal tubular impairment (OR=4.251,P=0.002).Conclusions Renal tubular functions is decreased with ageing age in the elderly male,especially in the advanced elderly.The coronary heart disease is an independent risk factor of the progression of renal tubular impairment.

Objective To investigate the change of renal tubular function in elderly patients after use of β lactam antibiotic. Methods The elderly patients with pulmonary infection were treated with β lactam antibiotic,the dosage was 50%-70% of normal use. The renal tubular function indicated by urine α1-MG, β2-MG, pro/Cre, NAG/Cre and glomerulus function marked by eGFR, serum creatinine (Cre)), cystatin C were detected during drugs treatment and 7 days after stopping medications. Results The infection was controlled well in 3-7 days after treatment. Urine α1-MG, β2-MG, pro/Cre and NAG/Cre were abnormal before treatment, were elevated in 3, 14 days after using antibiotic, and came down to the level before treatment on 7 days after stopping treatment. The level of Cre and eGFR was (89.0±25.97) μmol/L and (26.39±8.17) ml/min before treatment, then elevated and decreased in 14 days after treatment, respectively, and down to the level before treatment on 7 days after stopping of antibiotic. Cystatin c was abnormal before treatment and did not change significantly after treatment and after stopping antibiotic. Conclusions It is important to protect renal tubular function and to adjust antibiotic dosage according to eGFR during using antibiotic in elderly patients to control infection.

OBJECTIVE:To study the protective effects of total flavone from Prunus cerasifera fruits(PCE)on alcoholic liver disease(ALD)in rats,and provide experimental basis for developing new medicines for anti-ALD. METHODS:40 rats were ran-domly divided into normal group(distilled water),model group(distilled water),silibinin group [positive control,30 mg/(kg·d)] and PCE high-dose,low-dose groups [80,40 mg/(kg·d)],8 in each group. All rats were intragastrically administrated(10 mL/kg) every morning,once,for 6 weeks;meanwhile,except for normal group,rats in other groups received 50% alcohol(10 mL/kg) once intragastrically every afternoon to induce ALD model. After administration,heart,liver,spleen and other organ indexes,sub-cutaneous fat,brown fat,abdominal fat indexes were determined,as well as serum biochemical indexes [glutamate transaminase (ALT),aspartate aminotransferase(AST),total bilirubin(TBIL),direct bilirubin(DBIL),indirect bilirubin(IBIL),gamma-glu-tamyl transpeptidase(GGT),and total cholesterol(TC),triglyceride(TG),high-density lipoprotein(HDL),low-density lipopro-tein (LDL)] level and liver biochemical indexes [superoxide dismutase (SOD),malondialdehyde (MDA),glutathione peroxidase (GSH-Px),TC,TG] and TC,TG levels in feces;pathological changes of liver and kidney tissues were observed. RESULTS:Compared with normal group,heart,liver,spleen indexes,subcutaneous fat,abdominal fat indexes in model group were in-creased(P<0.05 or P<0.01),brain index and brown fat index were decreased(P<0.05);HDL level and HDL/TC ratio in serum were decreased,other serum indexes were increased(P<0.05 or P<0.01);SOD,GSH-Px levels in liver tissue were decreased, other above-mentioned liver biochemical indexes were increased(P<0.01);TC,TG levels in feces were increased(P<0.01);liv-er and kidney showed obvious lesions. Compared with model group,the above-mentioned indexes in silibinin group and PCE high-dose group were significantly improved (P<0.05 or P<0.01);ALT,AST in serum and MDA level in liver tissue in PCE low-dose group were significantly decreased(P<0.01),and SOD,GSH-Px levels in liver tissue were significantly increased(P<0.05);lesion degree of liver and kidney and lipid accumulation in liver were reduced in administration groups. CONCLUSIONS:PCE may play a role in anti-ALD by anti-oxidation,promoting liver cell regeneration and regulating lipid metabolism.
