To investigate the interrelationship between plasma renin activity(PRAXaldosterone (Ald),atrial natri-uretic peptide ( ANP ) and blood volume ( BV ) in adult nephrotic syndrome ( NS ) . Methods BV was assessed using 113mInCl dilution method. PRA、 Angiotensin Ⅱ (AngⅡ)、Ald、ANP were determined by radioirnmunoassay. 28 edema-tous NS patients,26 healthy controls and 18 cases of remission were involved. Results (1)During edematous period, PR, AngⅡ , Ald、 ANP were higher in NS than in controls. There was no difference of BV between NS and controls. Albumin ,PRA,AngⅡ 、Ald and ANP were not correlated with BV; (2)After remission, comparing with edematous period, Ald 、ANP deceased significantly whereas PRA、AngⅡ、Ald and total BV were not different; (3) Urine natrium excretion (UNaV) was negatively correlated with Aid. Conclusion Ald and ANP may be the major regulating factors of sodium excretion in nephrotic syndrome.

BACKGROUND: It is of significance to imitate facial nerve paralysis of temporal trauma, establish the model of facial nerve paralysis, and study the histopathologic changes of facial muscle after denervation and the effect on rehabilitation of facial muscle function.OBJECTIVE: To investigate the relationship between rehabilitation of facial muscle function and the structural changes of mitochondria and succinate dehydrogenase (SDH) of oris muscles after denervation.DESIGN: A randomized controlled trail based on experimental animals.SETTING: Department of otolaryngology in a hospital of a university.MATERIALS: The experiments were conducted in the Center of Animal Experiment, the Department of Histoembryology, and the Second Electron Microscope(EM) Center, China Medical University. Sixty white guinea pigs provided by the Center of Animal Experiment, China Medical University [certification No: SCXK (liao) 2003-0009 ], were randomly divided into three groups, 5 s squeezed group( n = 15, 10 tested for the function of facial muscle, 5 for EM specimen 15 days after operation), 15 s squeezed group( n =20, 10 tested, 5 for EM specimen 15 days and 30 days after operation), and 30 s squeezed group( n = 25, 10 tested, 5 for EM specimen 15 days after operation and 10 for EM specimen 30 days after operation).INTERVENTIONS: Models of facial paralysis were established. The threshold of facial nerve was detected with electroneurogram(ENoG) before and after squeezed, and the duration of the functional recovery of facial muscle was observed with blink reflex. Orbicularis oris was taken for SDH cytochemical staining, and the ultrastructural changes of SDH positive reaction granules,mitochondria and muscle fibers were observed under transmission electroscope.MAIN OUTCOME MEASURES: ENoG threshold value, tine for recovery of facial muscle function, SDH positive reaction granules and ultrastructural changes of mitochondria and muscle fibers.RESULTS: In 5 s squeezed group, the average inhibition time of nerve excitement conduction was(35.2 ± 16.8) minutes, the structure of mitochondria and the positive reaction granules of SDH remained normal, and the muscle fiber had no pathologic changes. In 15 s squeezed group, it took an average of(47 ± 15) days for blink reflect to recover. In 15 s squeezed group of 15 days, the mitochondria showed slight bubble degeneration and the SDH granules decreased and the muscle fiber had slight pathologic changes, but recovered after 30 days. The mitochondria changed severely and SDH granules decreased significantly in 30 s squeezed group of 15 days and 30 days; no case of blink reflect recovered within' half a year.CONCLUSION: The longer the facial nerve is injured, the nore severely the function of facial muscles is damaged, and the more difficultly it will recover. Therefore, facial nerve decompression should be performed as early as possible.

Objective:To explore the mechanism of renal injury in severe acute pancreatitis(SAP).Methods:54 SD rats were randomly divided into sham operation group(n=24) and SAP group(n=30).SAP model was induced by injection of 5% sodium taurocholate solution into bilo-pancreatic duct.Rats from each group were killed and the serum and ascite were collected at 6h,12h,24h after operation.Tumor necrosis factor-?(TNF-?)level of serum and ascite were measured by enzyme linked immuno-sorbent assay (ELISA).The expressions of TNF-? mRNA were assessed by RT-PCR analysis.The serum and ascites that had been collected at 24h after development were injected into medium of NRK cell,then the levels of TNF-? secreted by NRK cell were measured after injection 6h,12h,24h,and the cell apoptosis were also evaluated after injection 24h.NRK cell apoptosis were evaluated by flow cytometry (FCM).Results:①The serum and ascites levels of TNF-? were signficantly elevated in SAP groups compared with sham operation groups at any time point(P

AIM To explore the effects and mechanism of cobra venom serum on the proliferation in HL60 cells. METHODS Established the HL60 cells as a target to study the growth feature by the action of cobra venom serum.The agarose gel electrophoresis and flow cytometry analysis were used to demonstrate apoptosis. RESULTS Compared with the control group, the cells were inhibited significantly by the action of cobra venom serum.A characteristic DNA "ladder" was detected by using agarose gel electrophoresis. By flow cytometry analysis,it was proved that most apoptosis of HL60 cells occurred when cultured with cobra venom serum. CONCLUSION Cobra venom serum inhibited the HL60 cells in vitro , which was related to apoptosis. This may introduce a new way to the treatment of leukemia.

Objective To evaluate tension-free repair in the management of recurrent inguinal hernia. Methods From 1/1993 to 12/2002, 163 patients with recurrent inguinal hernia underwent reoperation, clinical data were reviewed. Results The male: female ratio was 138: 25, age from 34 to 76 years. The primary surgery had been traditional hemiorrhaphy without prothesis in 142 cases (87. 1 % , including 65 cases of Bassini ,35 cases of McWay and 42 cases of Shouldice) , a tension-free procedure in 12 cases(7. 4% , including 3 cases of laparoscopic mesh repair) and unknown techniques in 9 cases(5. 5% ). The average interval from the initial surgery to recurrence was 36?14 months (range from 3 months to 10 years). Recurrent hernias were treated with a Shouldice repair in 71 cases(43. 6% ) , a tension-free repair in 92 cases(56. 4% , including a laparoscopic mesh repair in 3 cases). All these 163 cases(100% ) were followed up for 56 ?1 months (range from 30 months to 12 years) after the second surgery. It was found that after reoperation the recurrence rate of Shouldice procedure and tension-free repair was 16. 1% (11/71) and 2. 2% (2/92) respectively (x2 = 8. 327 ,P

Objective To explore the effect of early enriched environment intervention on expression of neurofilament protein (NFP) in brain and the neurobehavior of filial rats with brain injury.Methods The pregnant Wistar rats of lipopolysaccharide (LPS) group were consecutively injected intraperitoneally with LPS on the 17th and 18th day of gestation while the control group only received an injection of same dose of 9 g/L saline.All premature rats,whose gestational age was less than 22 days,were removed from both groups;While the full-term newborn rats were chosen.After delivering,the uterus and placenta were taken out immediately to examine the infection situation by HE staining.Twenty-four hours after born,the brains of the newborn rats were taken out to observed the white matter damage by HE staining.LPS group was randomly divided into 2 groups:intervention group and non-intervention group.The intervention group was treated with neonatal handling and enriched environment from postnatal 8 days,while no management was performed in control group and non-intervention group.Ethological examination was tested with hanging test,and immunohistochemical technique was used to detect the expression of NFP,when the neonatal rats were 21 days old.Results There were a large amount of neutrophilic granulocyte in the uterus and placenta in LPS-treated group; In the 1-day-old rats in LPS group,brain tissue pathology test showed diffuse white matter lucencies.The scores of hanging test in control group was the highest,the ones in non-intervention group was the lowest among the 3 groups,and there was significant difference between them (Pa
