ABSTRACT

Objective To investigate the effect of diabetes on clinical efficacy of transcatheter arterial chemoembolization (TACE) in the treatment of non-viral hepatitis hepatocellular carcinoma (HCC). Methods Retrospectively analyzed the clinical data of 367 non-hepatitis virus HCC patients treated by TACE, included 153 diabetes mellitus cases (test group) and blood glucose of 214 patients was normal (control group). To assess the treatment effect after 1 month of TACE based on response evaluation criteria in solid tumors, include complete response (CR), partial response (PR), stable disease (SD), progressive disease (PD), and calculate the disease control rate. Through 6 to 75 months follow-up to observed long-term efficacy, record the time to progression (TTP) and overall survival (OS) time. Survival rate were analyzed using Kaplan-Meier method and Log-rank analysis by SPSS 16.0. The single-factor analysis was used to analyze variables which variables that differed were analyzed by Cox regression. Results The disease control rate of test group was 69.9%(107/153) and control group was 74.3%(159/214), the difference was no statistically significant (P=0.125). The median time to progression (mTTP) and median overall survival (mOS) of test group were 10.0 and 15.0 months;and the mTTP and mOS of control group were 14.0 and 19.0 months, the difference were statistically significant (P=0.023 and P= 0.026). Tumor diameter ≥4.5 cm, numbers of tumor ≥3, invasion of blood vessels, α-fetoprotein≥200 μg/L, Eastern Cooperative Oncology Group score and diabetes were risk factors for OS of HCC patients. Conclusion Diabetes is unfavorable factors for overall survival of non-hepatitis HCC tread by TACE.

ABSTRACT

Objective To compare the efficacy and side-effects of preoperative neoadjuvant uterine arterial chemoembolization and venous chemotherapy in treating cervical cancer in young female patients. Methods A total of 241 young females(≤35 years old) with cervical cancer were enrolled in this study. The clinical data were retrospectively analyzed. The patients were divided into group A (n=63) and group B (n=57). Patients in group A received preoperative neoadjuvant uterine arterial chemoembolization with subsequent surgery, while patients in group B were treated with preoperative neoadjuvant intravenous chemotherapy followed by surgery. The chemotherapy scheme included carboplatin (50 mg/m2) and gemcitabine (1 000 mg/m2). The short-term effect, the amount of blood loss during the surgery, pathological findings and the side-effects of the two groups were compared. The Kaplan-Meier method was used to calculate survival rate, and the log-rank test was used for survival difference analysis. Results The short-term response rate of group A was 90.5%, which was significantly higher than that of group B (71.9%), the difference between the two groups was statistically significant (χ2=7.5, P0.05). In both groups, the clinical stage, the pathological grade and the size (≥ 4 cm) of the tumor were the main factors that could influence the prognosis in young females with cervical cancer (P<0.05). Conclusion The short-term efficacy of preoperative uterine artery chemoembolization is better than that of preoperative intravenous chemotherapy for the treatment of cervical cancer in young female patients. Besides, this therapy carries mild side effect, and it can improve the 5-year progression-free survival rate, although the long-term survival rate has not been obviously improved.

ABSTRACT

Aim To investigate the effect of flavonoids from Prinsepia utilis Royle( FPR) on the histomorphol-ogy of kidney in diabetic mice, and to investigate its protective mechanism. Methods Diabetic mice in-duced by alloxan were given FPR orally each day for four weeks. After the administration for two and four weeks, ten mice in each group were randomly sacri-ficed. The kidneys were removed and weighed. The extracted renal tissue was embedded with paraffin and sectioned, the sections were stained with Hematoxylin and Eosin(HE)、Periodic acid Schiff(PAS) and Go-mori, and then observed under the microscopy. 1mm3 of renal cortex fixed with glutaral in four centi-degree , and then the ultrastructure of each group was observed under the electron microscope respectively after four weeks′ treatment. Results Compared with the model control group, in the treatment group, observation un-der the microscopy showed that glomerular volume and mesangial cells reduced, FPR could relieve thickening of the glomerular basement membrane ( GBM ) , little inflammatory cells infiltrated in the interstitium,tubular epithelial cells almost became normal, renal tubule had little glucogen, fiber decreased in the interstitium of renal tubule. Observation under the electron micro-scope indicated that foot process in podocytes lined up in order, mitochondria of the renal tubule’ s epithelial cell almost recovered. Conclusion FPR can relieve the changes of renal pathology,improve renal function, and delay the progression of pathologic changes of kid-ney in diabetic mice partly through reducing the blood glucose and the blood lipid.

ABSTRACT

Objective To explore the long-term effect of bronchial artery, embolization (BAE) in patients with massive hemoptysis and the factors associated with prognosis. Methods Ninety six patients underwent BAE from 2002 to 2008 for the management of mass hemoptysis were retrospectively analyzed. Of them, BAE was successfully performed in 94 patients (mean age 43 years, age range 21 to 80 years), including active or inactive tuberculosis (89 cases), bronchiectasis (2 cases) and pulmonary carcinoma (5 cases). Results BAE resulted in an immediate cessation of hemoptysis in 94 of the initial 96 patients (97.9%). The rate of hemoptysis controlling at 30 d, 90 d, 1 year and 2 year after the BAE was 93.6% (88/94), 86. 2% (81/94), 81.9% (77/94) and 78.7% (74/94) respectively. Haemoptysis recurred in 9 patients in 30 days after the BAE due to missing of target vessel or recanalization. Five patients had recurrence of haemoptysis after 30 days and 2 patients recurrent after 90 days due to development of systemic collateral, progress in primary lesions and secondary infection. Conclusion BAE is an effective technique in the emergency treatment of massive hemoptysis. Avoiding missing target vessel, selecting the appropriate embolic material, paying attention to treatment of the primary disease after BAE, and preventing infection would improve the effects of BAE for massive hemoptysis.
