Forty-two patients with type 2 diabetes mellitus (DM) were refered to 3 groups:type 2 DM without diabetic nephropathy (DN),type 2 DM with DN in the initial stage and type 2 DM with DN in the clinical stage.Ten healthy subjects were served as control group.Plasma adrenomedullin (ADM),urinary?_1- microglobulin (MG) and?_2-MG were detected.The results showed that the level of plasma ADM rose gradually with the development of DN and was positively correlated with markers of tubulointerstiial injury such as urinary?_1- MG and?_2-MG (both P

Objective To evaluate the usage of renoportal anastomosis in the liver transplanta- tion.Method The successful experience about renoportal anastomosis for portal vein reconstruction in liver transplantation was reported,and related literature reviewed.Results Including our case,there have been 13 cases of liver transplantation using renoportal anastomosis for portal vein reconstruction. Among these patients,8 cases were complicated with diffuse portal vein thrombosis,and 10 cases had a splenorenal shunt(spontaneous shunt in 3 and surgical shunt in 7).Complications related to portal vein hypertension occurred in 3 cases(transient ascites in 2 cases and severe digestive bleeding in 1 case)after liver transplantation.There were 3 deaths which were not related to renoportal anastomo- sis.Conclusion Renoportal anastomosis is a safe and feasible technique in liver transplantation for the patients with diffuse portal vein thrombosis or with splenorenal shunt(spontaneous or surgical shunt).

Objective To study the effects of salt sensitivity on evolution of blood pressure and develope- ment to hypertension from adolescents to youth.Methods A baseline survey was carried out in 4623 adolescents aged 6-15 years old in Hanzhong rural area in 1987,310 of them were recruited for determination of salt sensitiv- ity using the tests of oral saline load and furosemide sodium-volume depletion.Salt sensitivity (SS) were diag- nosed in 101 while 209 subjects as no-sah sensitivity (NSS).This cohort of adolescents were followed up for av- erage 18 years.Results The response rate for this cohort of adolescents was 71.9%.At the end of follow up period,BP in subjects with baseline SS was higher in youth than that in NSS (SBP:122.9?13.1 vs 117.3?12.4, P

Factors influencing the temperature-sensing accuracy of an ablation catheter are analyzed, in this paper, from the two aspects of the thermocouple temperature sensor, which are the TC length and the TC hole's diameter of the ablation electrode. Meanwhile, differences between products from different companies are given too.

OBJECTIVETo investigate the characteristics of father-to-son vertical transmission of Y chromosome microdeletions

METHODSWe detected the Y by detection of Y chromosome microdeletions in infertile men and analysis of some of their families. chromosome azoospermia factor (AZF) microdeletions in the peripheral blood of 1 052 infertile males, investigated the paternal relatives of 12 cases of AZFc, 1 case of AZFb and 1 case of AZFb + c microdeletions, and drew the family tree diagrams of the infertile paternal relatives according to the findings.

RESULTSAmong the 1 052 infertile patients, 89 (9.73%) were found with Y chromosomal microdeletions, including 56 with AZFc, 6 with AZFa, 5 with AZFb, 14 with AZFb + c, and 8 with AZFa + b + c deletion. The investigation of the 14 patients'families revealed 1 case of AZFb and 1 case of AZFb + c deletion de novo. Among the 12 cases of AZFc deletion, vertical heredity was found in 5 patients with severe oligozoospermia, but not in the other 7 with azoospermia.

CONCLUSIONAZFe deletion may be vertically inherited from the father in severe oligozoospermia patients, and it is different from the paternal phenotype, while in azoospermia patients, AZF deletion, whatever type it may be, is less likely to be associated with vertical paternal heredity.

OBJECTIVETo analyze micromovement of distal tihiofihular joints in different motion range of ankle joint ,and define the micromovement characteristic and range of distal tibiofihular joints.

METHODSTwelve normal Chinese were chosen. There were 9 males and 3 females, aged from 19 to 37 years old with an average (26.5 +/- 0.5) years. Detection terminals of laser photographic scanner were installed near the highest point between medial malleolus and lateral malleolos, the change of detection terminals on the position of dorsiflex, extension, introversion and eversion of ankle joint were scanned by 3D-laser scanner. The displacement of two detection terminals on the X ,Y and Z-axis (X-axis stands for the vertical-axis between coronal plane and Z-axis Y-axis stands for the vertical-axis between sagittal plane and Z-axis Z-axis stands for macroaxis of tibia).

RESULTSAlong with increased range of motion on the position of dorsiflex ,extension, introversion and eversion of ankle joint, the range of micromovement of distal tibiofibolar joints increased too. The max-displacement of X, Y and Z were respectively (1.04 +/- 0.12) mm, (1.70 +/- 0.16) mm and--(0.87 +/- 0.10) mm.

CONCLUSION3D-laser scanner can be used to determine the detailed displacement of distal tibiofibolar joint on the X , Y and Z, and measure the motion of distal tibiofibular joint. The method can be used to study the pathologic change of distal tibiofibular joint ,and provide basic biomechnics data for internal fixtor fitting for the characteristic of distal tibiofibular joint.

Objective To retrospectively analyze 45 cases of oral and maxillofacial malignant tumors and to assess the efficacy and feasibility of oral and maxillofacial malignant tumors implanted with 125I radioactive seeds under guidance of ultrasound.Methods A total of 47 focuses in these 45 patients were determined with the size of these tumors by imaging study,the section was planed by ultrasound,the number and distribution of radioactive seeds were determined with the help of the particle treatment planning system,and were percutaneously implanted particles under guidance of ultrasound.The number and the distribution of particles were assessed by CT.Efficacy endpoints were reexamined and evaluated regularly by ultrasonic and CT according to the standards of WHO.Results The total percentage of efficacy was 70.2% (including complete remission,partial remission).The treatment effect of metastatic carcinoma of lymph node is superior to the parotid tumor.There was no serious complication during the period of implanting and 2 patients with oral ulcers were found after operation.Conclusion The oral and maxillofacial malignant tumor treated implanted with 125I radioactive seeds under guidance of ultrasound is very effective and safe,which is deserved to popularize.The ultrasound is the first choice as a guided method for oral and maxillofacial malignant tumors.
