The present study was undertaken to observe the effect of picrotoxin(PT) injection into lateral ventricle (LV) on cardiac contractility (CC) and renal nerve discharge (RND).lt was found that PT injection into LV caused CC and RND to increase significantly, and this effect was dose-dependent.The effect of baroreflex on cardiovascular response produced by PT injection was also observed. Data suggested that PT injection into LV still caused CC and RND to increase when the buffer nerve was sectioned. The magnitude of increase was significantly larger than that of the intact buffer nerve. The results indicate that in the CNS, the block of gamma-aminobutyric acid (GABA) transmitter system not only could cause blood pressure and heart rate to increase, but also strengthen CC and RND; baroreflex could partly suppress cardiovascular response caused by PT injection.

Objective To study the potential effects of telomerase inhibitor on the apoptosis of bladder cancer cells. Methods A phosphorothioate oligonucleotide (PS ODN) with sequence 5′ d(TTAGGG) 3′, as the telomerase inhibitor, was incubated with a bladder cancer cell line EJ. Such treated cells were studied with many approaches for the telomerase activity, the growth status and the morphological changes. Results The PS ODN inhibited the telomerase activity in the cells, arrested the cell growth, and induced the apoptosis of the cells. Conclusions The apoptosis of bladder cancer cells could be induced by PS ODN with 5′ d(TTAGGG) 3′ sequence as a telomerase inhibitor.

20?10 6/L were observed in the blood. No patients presented bone pain, fever, abnormal function of liver and kidney, and so on. Conclusions:Our results indicated that rhG-CSF is efficacious and safe in auto-PBSCT for patients with plasma cell diseases. Therefore, the expense of hospitalization would be reduced significantly.

Objective To study the clinical significance of changes of plasma nitric oxide (NO) and tumor necrosis factor (TNF) levels in patients with congestive heart failure (CHF).Methods Plasma NO and TNF in 68 CHF cases were tested.30 healthy subjects served as normal controls.Results Plasma NO and TNF levels in CHF patients were obviously higher than those in normal subjects (P

Objective To study the clinical features,the diagnosis and treatment of left renal entrapment syndrome. Methods Four male patients with left renal entrapment syndrome were reported.Their age ranged from 16 to 22 years.The clinical features were characterized by recurrent episodes of gross hematuria,and 1 case had left varicocele concomitantly.Cystoscopy showed hematuria from the left ureter orifice.B-ultrasonography and CT scan showed that the left vein was clearly compressed at the included angle of abdominal aorta and superior mesenteric artery and the proximal vein was dilated in all the 4 patients.The characteristics of onset and imaging, and treatment of left renal entrapment syndrome were reviewed and discussed with the relevant literature. Results The diagnosis was established in the 4 cases based on B-ultrasonography and CT scan.Left renal vein reconstruction was performed on them.The patients were cured and discharged,with renal vein outflow being normal and no hematuria occurring.At 6 and 9 months after operation,CT and ultrasonography showed that the kidney contour was normal,the reconstructed veins were patent,and the routine urine test results were normal. Conclusions Left renal entrapment syndrome clinically results in high pressure of renal vein,hematuria and left varicocele.Autotransplantation of the left renal vein is an effective treatment option.

Objective To sum up the clinical experience of the diagnosis and treatment of membranous glomerulopathy associated with chronic graft-versus-host disease(cGVHD) following allogeneic stem tell transplantation(alloSCT).Methods One case of acute acute lymphoblastic leukemia(received) HLA complete matched alloSCT and subjected to methopterin and Tacrolimus(FK506)postoperatively for prevention of GVHD.Nineteen days after operation,the patient suffered from(acute) GVHD and recovered by using methylprednisolone.On the day of 182 and 235 after transplantation,FK506 and prednisone were withdrawn.Five days later,cGVHD occurred,showing liver(dysfunction) and nephrotic syndrome.Membranous glomerulopathy(stage II) was pathologically (diagnosed) and treated with FK506 and prednisone.Results In membranous glomerulopathy,the(patient) got albuminuria(++++),leukocytes 75/?L,epicytes(359.5)/?L,pathological casts(+),24-h urine protein(4.28) g.Renal biopsy revealed that glomeruli were slightly enlarged,partial(capillary) compressed to be closed,glomerular basement membrane(GBM) was slightly thickened and mesangium slightly proliferate.Masson stain indicated the deposition of pink material along the glomerular capillary walls.And IgG(+++),C3(+++) and IgA(++) were detected at the GBM in a granular pattern by immunofluorescent stain.Electron microscopy showed numerous subepithelial(deposits).After treatment with prednisone and FK506 for 2 months,proteinuria was gradually(decreased).Conclusions GVHD associated membranous glomerulopathy should be considered when the patient got nephrotic syndrome or proteinuria after alloSCT.Renal biopsy is beneficial to the diagnosis of GVHD.Glucocorticoid and FK506 is effective in the treatment of GVHD.

To evaluate the role of the vagal afferents in the generation and formation of high frequency oscillation (HFO), effect of selective electrical stimulation of A?-? afferent fiber groups of the vagus nerve (0.4-0.5 V, 0.1ms, 5-160 Hz), applied at three respiratory phases: inspiratory phase (IS), expiratory phase (ES), and continuous phase throughout both IS and ES (CS), on the phrenic HFO was quantitatively assessed on ether-anesthetized, vagotomized, paralyzed and artificially ventilated rabbits. After calculation of the power spectrum of the efferent phrenic nerve activity, the mean square values (MSV), representing total amount of HFO-output, and the peak frequency of the HFO were estimated by means of curve-fitting method. Regardless of the mode of the stimulation, the MSV decreased in a stimulus-frequency dependent fashion. The CS was most potent, then IS, and ES was less effective, though the reduction was significant (p

Objective To analyse the clinical and pathological features of cystadenocarcinoma in the intrahepatic biliary tract. Methods The clinical features of 14 patients with cystadenocarcinoma in intrahepatic biliary tract were analysed in respect to the results of ultrasonic and CT scannings, as well as pathological examination. Results Among the 14 patients, 11 were females and 3 were males. The age of the patients ranged from 32 to 79 years, and mean age was 59.5. The obvious symptoms were right-upper abdominal pain and abdominal distention, and major physical signs were hepatomegaly with cystic feeling. The ultra sonographic and CT scanning revealed cystic space occupying lesions in the liver. According to the invasion or infiltration of carcinoma to the liver tissue, the pathology of cystadenocarcinoma in intrahepatic biliary tract could be categorized into two types: the invading and non-invading. There were 8 patients belonging to the first type and they died 9～37 months after the diagnosis or operation, while 6 patients with no invasion were alive after operation. Conclusion The clinical picture and pathology of cystadenocarcinoma in intrahepatic biliary tract were described. The pathological classification was important in prognosticating the outcome of the patient.

Objective To evaluate the safety and clinical efficacy of photoselective vaporization of the prostate(PVP)for the treatment of benign prostatic hyperplasia(BPH).Methods Under caudal block,650 patients with BPH received PVP.By using the pointer,vaporization was started at the 6 o'clock point at the bladder neck and then extended to the 5 and 7 o'clock points,afterwards,the bilateral lobes of the prostate was involved deep into the prostate capsule.Results Five of the cases(8%)were converted to open surgeries because of large prostate or massive hemorrhage.In the other 645 cases,the mean operation time was(45.6?17.3)min,mean blood loss was(56.3?15.2)ml;none of them received blood transfusion.Urethral catheter was indwelled for(1.8?0.5)d after the operation in 504 cases.All the patients were followed up for 3 to 36 months.Three months after the operation,the IPSS and QOL decreased from(29.8?5.2)and(5.2?0.8)to(8.4?2.3)and(1.4?0.5)respectively in the patients(t=37.635,P=0.000 and t=39.084,P=0.000),RUV decreased from(168.0?22.5)ml to(24.6?5.8)ml(t=42.281,P=0.000),Qmax increased from(5.6?2.8)ml/s to(24.7?3.2)ml/s(t=-28.430,P=0.000),respectively.No urinary incontinence and TUR syndrome occurred in this series.Conclusions PVP,which can yield short operation time,little blood loss,and rapid relief,is safe,simple,and effective for patients with BPH,especially for elder patients.

Analysis was made in 3 patients with central nervous system lymphoma(CNSL) with different manifestations;neuroradiological and immunocytological investigations were used to improve the clinical diagnosis of CNSL.Three patients with CNSL presented with 3 distinct profiles:diffuse meningeal invasion, intracranial masses of tumor and intramedullary spinal invasion. Both contrast enhanced CT and MR provided CNSL lesions in the brain parenchyma and meninges. It is suggested that combining CT,MR findings and immunological markers can improve clinical diagnosis of CNSL.
