Objective To measure the renal tissue texture or flexibility with virtual touch quantization (VTQ) and to tentatively examine its clinical application in patients with chronic kidney disease(CKD).Methods A total of 750 patients (1500 kidneys) were performed with VTQ,including 400 cases in the control group,and 350 cases in the CKD group.A conventional ultrasound examination (two-dimensional,color Doppler) were first taken,and then the shear wave velocity (Vs) was measured which reflected the textural elastic.Results In both groups the Vs was the highest in renal cortex with significant difference (P<0.05); renal cortical region Vs in CKD group was lower than those in control group (P<0.05),while Vs of renal medulla and renal sinus had no significant difference in the two groups.The severity of renal dysfunction was increased along with a Vs decrease of renal cortex.Conclusion VTQ is helpful to assess renal function of patients with CKD.

Objective To observe the effect of artificial nose in the artificial airway humidity among the elderly patients with artificial airway. Methods Sixty-eight patients undergoing artificial airway at department of respiratory were randomly divided into 2 groups, 34 of them in the artificial nose airway humidity group, and 34 in the regular humidity group. The quantity of sputum secretion, times of sputum absorption, degree of airway humidity and acute reaction of respiratory tract were observed. Results The artificial nose airway humidity group was better than the regular humidity group in view of reducing the quantity of sputum secretion, times of sputum absorption, degree of airway humidity and acute reaction of respiratory tract, with significant meanings by the analysis of Chi square test and T test (P<0.01). Conclusions Artificial nose is superior to the method of regular humidity in respect of reducing the quantity of sputum secretion and times of sputum absorption, keeping well effect of airway humidification, and reducing the complications of artificial airway.

OBJECTIVETo investigate the precise locations of the blood vessels and nerves surrounding the seminal vesicles (SV) in men and provide some anatomical evidence for SV-related minimally invasive surgery.

METHODSWe observed the courses and distribution of the blood vessels and nerves surrounding SVs and obtained the data for positioning the SV neuroplexes in 20 male pelvises.

RESULTSOne branch of the neuroplexes was distributed to the SVs bilaterally with the neurovascular bundles, (2.85 ± 0.18) cm from the median sulcus of the prostate (MSP), while another branch ran through the Denonvillier fascia behind the SV, (0.81 ± 0.06) cm from the MSP. The arterial SVs (ASV) originated from the inferior vesical artery and fell into 4 types, 55% going directly to the SVs as one branch, 15% running between the SV and the ampulla of the deferent duct as another branch, 25% downward as 2 branches to the SV and between the SV and the ampulla of the deferent duct respectively, and 5% as the other ASVs. The shortest distance from the ASV through the prostatic neuroplexus to the posterior SV was (1.08 ± 0.09) cm.

CONCLUSIONIn SV resection, neuroplexus injury can be reduced with a bilateral distance of < 2.85 cm and a posterior distance of < 0.81 cm from the MSP, and so can bleeding by vascular ligation between the SV and the ampulla of the deferent duct.

Condition optimization for immobilization of Fungal laccase with Nylon Net and glutaraldehyde and the nature of the immobilized enzyme were studied. The optimum conditions of the immobilization are: Nylon Net is crosslinked with 5% glutaraldehyde 15mL for 6 hours; the 30U laccase is added for immobilization for 8 hours. On this case, the recovery of enzyme activity was 50.3%. Compared with free enzyme, the thermal stability of immobilized enzyme was improved evidently but the optimal pH decreased slightly. 52% enzyme activity of immobilized laccase was hold after 8 cycles treatment with low concentration pulp wastewater.

OBJECTIVE To investigate the HIV infections states in tumor patients for clinical diagnosis,treatment and to prevent HIV infection in the tumor hospital.METHODS The result of HIV detection in tumor patients from Dec 2000 to Aug 2006 was analyzed by the review statistics analysis.RESULTS Totally 48 101 tumor paients were detected,and the number of tumor patients with positive HIV antibody result was 51(0.106%).Among the positive patients there were 21 cases with blood transfusion history,14 cases with blood donating experience,2 cases with both these two kinds of experiences and 14 cases without the two kinds of experiences.Their rate was separately 41.0%,27.5%,4.0% and 27.5%.Most of the HIV positive patients had no clinical synptoms.CONCLUSIONS The HIV positive rate of patients with blood transfusion or blood donating is significantly higher than the patients without these experiences.The routine detection for the HIV before the operation,blood transfusion or other traumatic detection is very necessary.

Background Chronic administration with inhibitor of nitric oxide synthase (N_?-nitro-L-arginine methyl ester,L-NAME) induces persistent hypertension,cardiovascular remodeling,surrounding vascular fibrosis, necrosis and hypertrophy of myocardium,and inflammation in cardiovascular system.Local RAS involves in hyper- tension and remodeling of cardiovascular system,via increasing production of oxygen free radicals (OFR).Objec- tive To elucidate the preventive and therapeutic effect of antioxidant Ebselen and/or VitE on hypertensive heart damage in NO~- deficient rats induced by L-NAME.Methods Thirty-two Wistar rats were administered with L- NAME 50 mg/(kg?d) by gavage for 8 weeks,and randomized to received a placebo(L),or Ebs(S,30 mg/kg?d), or VitE(V,40 mg/kg?d) or Ebs 30 mg/(kg?d)+VitE 40 mg/(kg?d),with 8 normal Wistar as control. Body mass and SBP were measured fortnightly.Plasma and homogenate of heart were collected for NO,Ang Ⅱ, GSH-PX,MDA and O_2~- determination.Results Eight weeks after L-NAME administration,SBP in experimental groups was obviously higher than that of control (P

Objective To summarize the clinical characteristics and diagnosis of hemiconvulsion-hemiplegia-epilepsy(HHE) syndrome.Methods The clinical data of 5 children with HHE syndrome were analyzed.Cranial magnetic resonance imaging MRI and /or computerized tomography(CT) and electroencephalogram(EEG) were done in all patients.Results The age of onset was less than 4 years in 4 of 5 patients and initial seizures were associated with fever in 3 cases.The longest duration of convulsive seizures lasted more than 2 hours in all cases,followed by the appearance of hemiplegia involving the side of the body where the convulsions were localized.Subsequent epilepsy developed within 2 years of the hemiplegia in all 5 cases,with 4 cases simple partial seizure and 1 case psychomotor seizures.All cases had mental retardation.Cranial MRI showed left hippocampal sclerosis in 4 patients and CT brain scan showed right cerebral hemiatrophy in 1 case.The EEG showed abnormality in all patients.Epileptiform discharges were found in 4 cases,and the damage hemisphere showed slowing and low voltage of background activity in 1 case.All cases received mainly carbamazepine therapy,and the seizures were satisfactorily controlled or partly controlled.Conclusions HHE syndrome is recognized as hemiplegia-epilepsy syndrome after prolonged hemiconvulsion.The hippocampal sclerosis may be the consequence of repeated seizures,but not the cause.Better understanding of the syndrome,early and adequate treatment of prolonged seizures,especially of febrile convulsion,will reduce the incidence of HHE syndrome.
