Objective:To discuss the relationship between the serum level of interleukin-6 (IL-6) and the presence of an intrauterine contraceptive device (IUCD). Methods:The experimentalgroup was subdivided into the bleeding and the non-bleeding groups which consisted of 64 womenwith IUCD. There were 60 healthy women in the control group. The serum levels of IL-6 and C-reactive protein (CRP) were detected by enzyme-linked immunosorbent assay (ELISA) in bothgroups. Results :In the experimental group,the serum levels of IL-6 in 3 cases were increased,andthere was a significant difference in comparison with those of the control group (P<0. 01),butthere were no statistical differences between the bleeding group and the non-bleeding group withIUCD (P>0. 05). Serum CRP was negative both in the experimental groups and in the controlgroup. Conclusion:The non-bacterial endometrial inflammation induced by IUCD causes the in-crease of serum level of IL-6 in some women. It is suggested that IL-6 may play an important rolein the contraceptive mechanism of IUCD.

Objective To determine the influence of P-glycoprotein (P-gp) inhibitor on the blood brain barrier (BBB) transport of amphotericin B (AmB)..Methods An in-vitro BBB model was established with brain capillary endothelia cells (BCEC). AmB was chosen as the test drug and verapamil was chosen as the inhibitor of P-gp.Cellular uptake of AmB at different time points and with series of verapamil concentrations were performed respectively after the determination of appropriate incubation time and drug dosage by the cytotoxicity assay. The AmB concentrations of series of samples were detected using high performance liquid chromatography (HPLC) method. One-way ANOVA analysis and Bonferroni test were used for data analysis.Results The cellular transport of AmB was accumulated as the time prolonged.The inhibitor group had a significant higher cellular uptake levelsof AmBat the time point of 90 min (t=6.753,P=0.001),120 min (t=3.574,P=0.016) and 150 min (t=4.759,P=0.005) as compared with the control group.The AmB cellular uptake level increased significantly when BCEC were incubated with verapamil of 2 μmol/L (P=0.000),5 μmol/L (P=0.014),10 μmol/L (P=0.000),50 μmol/L (P=0.014),75 μmol/L (P=0.000) and 100 tμmol/L (P=0.000),respectively,compared with the control group.Conclusion The P-gp inhibitor verapamil can enhance the cellular uptake of AmB which indicates that P-gp is involved in the BBP transport of AmB.

Objective To evaluate the long-term clinical efficacy and toxicities of combined intracavitary hyperthermia and radiotherapy fur locally advanced uterine cervical cancer. Methods 310 patients with locally advanced uterine cervical cancer were assigned into intracavitary hyperthermia + radiotherapy group(TRT, 181 patients) and external-beam radiotherapy + traditional intracavitary radiation group (RT,129 patients). The external-beam radiotherapy were given with 60Co γ-my or 6-8 MV X-ray in traditional fractionation. In TRT group,radiotherapy was 40 Gy using the anterior-posterior pelvic fields and additional 20-25 Gy using the lateral fields. Hyperthermia was delivered by the 915 MHz microwave hyperthermia device within 15-60 min after external radiotherapy for 10-12 times(40 min each time,1-2 times per week). The temperature of tumor surface was 46-47℃. In the RT group, the external-beam radiotherapy of 40 Gy was delivered using the anterior-posterior pelvic fields. The intracavity radiotherapy of radium was delivered before 1989 ,with 50 mg radium in the vagina and 30 mg in uterine cavity for 24 hours ,weekly for 3 times to a total dose of 7200 mg·h. After 1989,intraeavity radiotherapy of 192Ir was delivered to a total dose of 30-36 Gy to point A in 5-6 Gy fractions,2 fractions per week. Results The 5-year survival of patients in TRT group and RT group was 67.4% versus 52.1% for stage Ⅱ disease (χ2=7.55,P=0.006), and 60.0% vemus32.3% forstage Ⅲ (χ2=7.06,P=0.007) . The 10-year survival was46.5% versus42.6% for stage Ⅱ (χ2=3.90,P=0.058), and 43.7% versus 20.6% for stage Ⅲ(χ2=17.28,P=0.000). Cox regression analysis showed that the tumor stage(P=0.023) and intracavitary hyperthermia( P=0.019) were prognostic factors. According to the RTOG criteria, the rate of mild to moderate late side effects of rectum and bladder in TRT and RT group was 17.7% and 33.1%, respectively (χ2=9.18, P=0.002). Rectovaginal fistula was developed in5 patients(3.9% ) in RT group and I patient (0.6%) in TRT group(χ2= 4.38,P=0.036). Conclusions The long-term survival of patients with stage Ⅲ uterine cervical cancer is better of TRT group than RT group. The TRT is well tolerated and the late toxicity rate is obviously low. It is necessary to carry out large randomized clinical trials to confirm these outcomes.

Objective To analyze the clinical features of patients with uncommon fungal infections in central nervous system (CNS).Methods Thirty-five patients with uncommon CNS fungal infections who were admitted to Huashan Hospital from 1997 to 2010 were retrospectively reviewed.The pathogens,symptoms and signs.treatments of patients were evaluated.The data were analyzed by rank sum test and Fisher'S exact test.Results Twenty-nine of the 35 patients met the definition criteria of prover CNS fungal infections,while the other 6 had probable diagnosis.Predisposing factors were found in 86% of all patients.The most common pathogens were Aspergillus and Candida species.The symptoms and signs commonly occurred including fever(22 cases),headache(19 cases), cranial neuropathy(12 cases),and meningeal irritation sign(12 cases).High white blood cell count,high protein level,and low glucose level were the main findings of cerebrospinal fluid (CSF) analysis.Patients with cerebral aspergillosis were more frequently accompanied with immunocompromised conditions, and they often got CNS aspergillosis from hematogenous dissemination or direct extension of paranasal sinus infection.Cerebral granuloma and abscess were the common clinical characteristics of CNS aspergillosis.Cerebral candidiasis often arose from neurosurgical surgery or traumatic brain injury,and these patients were usually presented with meningitis.All patients were treated with antifungal drugs and (or) surgical intervention and 77%(27/35) of the patients achieved complete or partial responses. Antifungal agents combined with surgical resection might improve outcome of patients with CNS aspergillosis; while removal or replacement of drainage tubes in combination with antifungal treatment showed satisfactory efficacy in patients with cerebral candidiasis who usually had shunt manipulation. Conclusions The incidence of CNS fungal infection, such as cerebral aspergillosis and candidiasis, is increasing. Early diagnose and therapeutic intervention are crucial for improving outcome.
