Objective To review the clinical changes and the management experience of hemodynamics after orthotopic heart transplantation.Methods Orthotopic homologous heart transplantation was performed on 25 cases from January 2000 to October 2003. The hemodynamic changes were monitored after operation with Swan-Ganz catheter and color Dopplor ultrasound. The therapy strategy was regulated when the monitor index and the clinical situation were referenced.Results PAWP, PASP, CVP, CO and CI were increased on the operation day. From the first day to the 7th day, PAWP, PASP and CVP were increased with right ventricle enlarged and sometimes arrhythmia and hydrothorax occurred. After strengthening heart, diuresis and stretching vessel, the hemodynamic changes of 23 cases were inversed and two cases’ conditions got worse. The two patients died of multiple organ failure on the 16th and 23rd day respectively.Conclusion The hemodynamic changes often occur at the early term after orthotopic heart transplantation. The main change is the right ventricular failure. It is important for the patient’s condition recovery and prognosis to monitor the hemodynamic changes and analyze the cause in order to direct the therapy.

ObjectiveTo study the efficacy of transcatheter arterial chemoembolization (TACE) combined with surgical resection in the treatment of ruptured hepatocellular carcinoma (HCC).MethodsThe clinical data of 26 patients who presented with ruptured HCC to our hospital from January 2008 to December 2011 were retrospectively studied. These patients received TACE (n=19),surgical resection (n=7),and surgical resection after TACE (n=8).ResultsShock in the 19 patients who received TACE was promptly corrected and the vital signs were stabilized.On subsequent CT,the tumors shrunk in size.Salvage liver resection was carried out in 8 patients 1 month after TACE.After treatment,AFP decreased or became normalized,thus the treatment results were good. A one-stage liver resection was carried out in 7 patients. One patient died after operation and peritoneal metastases occurred in 4 patients. Conclusions TACE stopped bleeding from ruptured HCC efficaciously,reduced the need for open exploration,and improved the rate of resection of HCC.TACE combined with surgical resection significantly lowered the rate of abdominal tumor metastases.

It has been 50 years since the discovery of thyrotropin receptor autoantibody (TRAb). Advances in the knowledge of thyrotropin receptor ( TSHR) structure and function, combined with the elucidation of TSHR signaling and TSHR-autoantibody interaction have greatly facilitated our understanding of TRAb and their clinical applications. Measurement of TRAb activity plays an important role in the diagnosis of Graves' disease ( GD) and Graves' opthalmopathy. It has also been well recognized that TRAb is an effective predictor of GD relapse or remission after antithyroid drug and radioactive iodine treatment. TRAb test is of particular help in pregnant women and lactating mothers with recent iodine load, where radioactive iodine or technetium tests are contraindicated. In addition, it is useful in the diagnosis and differential diagnosis of fetal and neonatal hyperthyroidism as well as some rare forms of thyrotoxicosis in clinical practice. Accumulating evidence also indicates the possible correlation between thyroid cancer occurring in GD patients with positive TRAb and adverse outcomes. However, further innovation and standardization of TRAb tests are required to help pave the way for clinical applications.

BACKGROUND:Clinical resection of thoracolumbar spinal tumor has a great impact on the spinal stability. Positive internal fixation is required clinicaly in order to maintain the spinal stability. The use of titanium mesh implantation can provide a firm internal fixation folowing resection of tumors. OBJECTIVE:To explore the spinal stability undergoing titanium mesh implantation with internal fixation folowing thoracolumbar tumor resection. METHODS:Twenty-four patients with thoracolumbar tumor admitted at the Central Hospital of Suining City from September 2013 to September 2014 were randomly selected and given tumor resection folowed by titanium mesh implantation with internal fixation. After treatment, patients were folowed up for 1-12 months to observe and analyze the neural functional recovery and spinal stability of the patients. RESULTS AND CONCLUSION:Al the 24 patients successfuly completed the operation treatment, and there was no case of death at the end of folow-up. During the folow-up, patient's clinical symptoms and neural function were significantly relieved, and Frankel classification was significantly improved after treatment. Regular X-ray examination showed that there was no change in the position of titanium mesh and anterior internal fixation system. There was also no titanium mesh colapse, internal fixation fracture and loosening, and the spinal stability was stil excelent. These findings indicate that patients were not changed, and did not appear because the amount of loose, good spinal stability. Resection of thoracolumbar tumors showed that the thoracolumbar spinal reconstruction with titanium mesh implantation combined with internal fixation folowing tumor resection can obtain good clinical effect and excelent biocompatiblity.

Objective To investigate the copy number changes on chromosome 3q26. 1 in urothelial carcinoma of the bladder, and to explore its potential clinical significance. Methods The microarray-based comparative genomic hybridization (Array-CGH) approach was used to analyze the genome-wide copy number changes of 35 tumor tissue samples of bladder cancer. To confirm the loss of a small fragment in 3q26. 1 detected by Array-CGH, real-time fluorescent quantitative polymerase chain reaction (real-time PCR) was performed with 57 frozen tumor tissue samples and 34 formalinfixed paraffin-embedded (FFPE) tumor tissue samples. The urine sediment cells collected from 15 healthy volunteers and 29 bladder cancer patients were checked as above. Results The Array-CGH data showed that the copy number loss of a small fragment in 3q26. 1 was detected in 77.1% (27/35)of the tumor tissue samples investigated. Real-time PCR analysis validated this loss of a small fragment of 3q26.1 with high frequencies in both 57 frozen tumor samples and 34 FFPE tumor samples.The percentage of samples exhibiting loss was 78.9% (45/57) and 100. 0% (34/34) respectively.Furthermore, the relative copy number of the 3q26.1 small fragment was significantly lower in the urinary sediment cells of the patients (median=0. 0020), comparing with that of healthy controls (median=0. 0030) (P<0.01). Conclusions Loss of the small fragment in 3q26.1 could be a characteristic genetic change of urothelial carcinoma of the bladder. It may serve as a potential molecular marker for bladder cancer.

AIMTo elevate the encapsulation efficiency, decrease the burst release and improve the release of protein entrapped in poly (lactic-co-glycolic acid) (PLGA) microspheres. The bovine serum albumin (BSA) composite microspheres of alginate-chitosan-PLGA were prepared and the release characteristics of BSA from this composite microspheres were studied.
METHODSThe much smaller calcium alginate microcapsules were first prepared by a modified emulsification method in an isopropyl alcohol-washed way and coated with chitosan, then the alginate-chitosan microcapsules were further entrapped in PLGA to form the composite microspheres. The protein concentration was determined using a BCA protein assay kit. The release profiles were changed with various formulation factors.
RESULTSThe average diameter of the composite microcapsules was about 30 microm. Comparing with 60% to 70% of the conventional PLGA microspheres, the average encapsulation efficiency was more than 80%, and the burst releases in phosphate buffer solution of the composite microspheres decreased from 40% and 50% to 25% and further to 5% in saline solution.
CONCLUSIONThe novel composite microspheres were prepared, the drug encapsulation efficiency increased and the burst release decreased. The desired release profiles could be obtained by regulating the ratios of PLG and PLA in the composite microspheres.
