Objective To evaluate the outcome of stereotactic aspiration combined with gamma knife radiosurgery in the treatment of cystic brain metastasis.Methods The study included 21 cases of cystic brain metastasis.There were 16 males and 5 females,with their age ranged 45～78 years old(mean,64.5 years old).Nineteen patients had a solitary tumor and 2 patients had two lesions.The mean diameter of tumors was 36 mm.The Karnofsky Performance Score(KPS) was ≥50%.A stereotactic aspiration was performed under CT guidance to drain the cystic fluid.Then the MASEP-SRRS gamma knife radiosurgery was performed.All brain metastasis were averagely enclosed within the 40%～65%(mean,50%) isodose shells of the radiosurgical fields with a peripheral dose of 16～22 Gy(mean,19.5 Gy).Results All the cases were followed for 1～3 months(mean,2.3 months) with CT or MRI scanning.Tumors completely disappeared in 12 lesions,subsided in 9 lesions,changed less than 10% in 1 lesion,and enlarged in 1 lesion.Cerebral necrosis and edema adjacent to lesions respectively developed in 1 case.No other severe complications were seen.The control rate of tumor was 95.7%(22/23).Twenty-one patients were followed for 6～36 months(mean,23.5 months).The followed-up results showed improvement of symptoms in 18 cases,no change in 2 cases,and exacerbation in 1 case.The survival rate at 6 months was 90.5%(19/21).And the 1-and 2-year survival rates were 62.5%(10/16) and 25%(3/12),respectively.One case survived beyond 3 years.The median survival time was 14.1 months.Conclusions Stereotactic aspiration combined with gamma knife radiosurgery is an ideal treatment for cystic brain metastasis.

Objective To observe the efficacy and toxicity of 5 -Fluorouracil plus cisplatin (FP)and docetaxel plus cisplatin(DP)in the treatment of patients with metastatic esophageal cancer.Methods A total num-ber of 68 cases of metastatic esophageal cancer confirmed by histopathology and (or)cytological examination was ana-lyzed retrospectively.There were 33 cases in FP group(5 -Fu 500mg/m2 ,d1 -5;DDP 20mg/m2 ,d1 -5,28 days a cycle),and 35 cases were in DP group(DTX 75mg/m2 ,d1,DDP 20mg/m2 ,d1 -3,21 days a cycle).The evaluation of efficacy and toxicity were performed on all patients per 2 cycles.Statistics and analysis of the difference between the two groups was performed.Results For FP group,CR was in 1 case,PR ere in 12 cases,SD ere in 16 cases and PD ere in 4 cases,respectively.The corresponding value was 3,18,11 and 3 for DP group.The objective response rate (ORR)for DP group(68.57%)was significantly higher than FP group(36.39%)(χ2 =5.83,P =0.02),and the disease control rate (DCR)were similar with no significance between the two groups(P =0.71).The Ⅲ -Ⅳ degree myelotoxicity for DP group was higher than for FP group with statistical difference (χ2 =7.07,P =0.01),while the incidence of nausea,vomiting,diarrhea and liver toxicity was similar (P >0.05).Conclusion DP regimen was more effective than FP regimen for the metastatic esophageal cancer,and the patients can tolerate with the slightly higher incidence of myelotoxicity,it was worthy of further study and clinical application.

Ketoprofen is widely used as non-steroidal anti-inflammatory drug. A potential sustained release ketoprofen tablet formulation was designed by orthogonal experiment on formulations composed of differential common excipients and homemade polymerides, and was screened by dissolution in vitro. The dissolution rate (%) of the ketoprofen tablet in simulated intestinal fluid was 16.6, 26.7, 42.2, 63.6, 83.1, 93.4, at 30min, 1, 2, 4, 6, 8 h, respectively. The plasma ketoprofen concentrations in six male volunteers were assayed after administration of a single oral dose (100 mg) of the sustained release tablet. It was found that the tablet formulation screened in vitro had sustained release effect in vivo too. This study suggests that there was a close correlation between the dissolution of sustained release ketoprofen tablet in vitro and the percent of dose absorbed in vivo, and the correlation coefficient was 0.9689. The influence of tablet hardness on the release rate of ketoprofen was also observed..

Objective:To find out markers of endometriosis. Methods: The two dimensional gel images of proteins extracted from eutopic endometrium from endometriosis patients and controls were analyzed by software Phoretix 2D,and the proteins expressed differently were identified primarily by query of data base.The proteins extracted from ectopic endometrium of ovarian endometriosis were transferred from two dimensional gel onto nitrocellulose membranes,followed by incubation with sera from women with and without endometriosis. Analyzed by MALDI-TOF-MS,the proteins hybridized differently were identified through their Peptide Mass Footprints. Results: Having compared the reproducible two dimensional gel images of proteins from eutopic endometrium of women with and without endometriosis,we obtained 11 proteins expressed differently.Through Western Blot technique,we found three proteins hybridized differently which were identified as vimentin,?-actin and ATP synthase ? subunit respectively. Conclusion: The protein expression spectra of eutopic endometrium from patients with endometriosis are significantly different from those of the controls,and the anti-endometrial autoantibodies against vimentin, ?-actin and ATP synthase ? subunit may be induced.

This study examined the correlation between osteoporosis and the degeneration of intervertebral discs. Sprague-Dawley rats were maintained up to 22 or 28 months. The femoral bone, tibial bone and lumbar vertebra were histologically studied and the expression of collagen type II and X in intervertebral discs was immunohistochemiscally determined. Several indices for the degeneration of intervertebral discs and osteoporosis and the correlation among them were then analyzed. Close correlations were found among the indices for the degeneration of intervertebral discs, including the relative area of the vascular bud, the ratio of the uncalcified and the calcified layers, the expression of collagen type II and X. The correlation with collagen type X was negative. There existed positive correlations among the indices for osteoporosis, including the thickness ratio of cortical bone, the relative area of bone trabecula, the density of femoral and vertebral body bones, and the maximum stress and strain on bone. Analysis on the relationship of osteoporosis and the disease on disc showed that the indices of osteoporosis were negatively correlated with the indices of the degeneration of intervertebral discs but the expression of collagen type X was positively correlated, with the density of vertebral body bones having the strongest dependence on collagen type X. The maximum stress and strain bore no correlation with the degeneration of intervertebral discs. These results suggest that osteoporosis was negatively correlated with the degeneration of intervertebral discs.

Aim To explore the role of endoplasmic re-ticulum stress( ERS) in Astragaloside Ⅳ-induced car-dioprotection against ischemia/reperfusion injury in rats. Methods A model of myocardial ischemia 30 min followed by 120 min reperfusion was made by liga-ting coronary artery in male Wistar rats. Rats were di-vided randomly into 4 groups: sham group, ischemia/reperfusion group, ERS inhibitor TUDCA group, As-tragaloside Ⅳgroup. Myocardial samples were collect-ed from the risk zones during ischemia and reperfu-sion, ERS was determined by measuring levels of glu-cose regulated protein 78 ( GRP78 ) , an established marker of ERS with Western blot. Immunofluorescence study was used to test GRP78 intensity with laser scan-ning confocal microscopy, TTC method was used to measure the infarct size,hematoxylin-eosin staining was used to observe the changes of morphological changes of myocardium. Results There was no statistical difference in GRP78 expression during ischemia com-pared to the sham group, but was markedly increased upon reperfusion. Astragaloside Ⅳ could mimic TUD-CA and significantly decreased the GRP78 expression, reduced infarct size and improved the morphology of myocardial tissue with a significant statistical difference compared with the control group ( P<0. 05 ) . Conclu-sions ERS is induced upon reperfusion but not during ischemia in isolated rat hearts. Astragaloside Ⅳ pre-vents myocardial reperfusion injury presumably by the inhibition of ERS.

BACKGROUND: At present, the researches on murine model of acute radiation encephalopathy are still in investigation, and mature model making method is not clear.OBJECTIVE: To establish a murine model of acute radiation encephalopathy in order to provide a good foundation for further researches of radiation encephalopathy(REP) mechanism and therapy.DESIGN: Randomized controlled study based on the experimental animals.SETTING: Animal laboratory in a university hospital. The Second Affiliated Hospital of Sun Yat-sen University.MATERIALS: The experiment was completed in the Laboratory of the Second Affiliated Hospital of Sun Yat-sen University from June 2001 to August 2002. Totally 30 female and 30 male SD rats, weighted(300 ± 30) g, were selected from the Animal Experiment Center of Sun Yat-sen University, and randomly divided into blank control group with 20 rats and experimental group with 40 rats.METHODS: Fourty rats' brain received 60Co γ-ray irradiation with the dosage of 7 Gy/time per day for 6 consecutive days with the total dosage of 42 Gy. The amount of ingestion and drinking, general activities, central nervous system(CNS) symptoms and signs were recorded every day. The hairs and skin of irradiated field and weight were checked and recorded weekly. On the 3rd, 7th, 14th, 30th days after radiation, the brain tissue was collected and the histopathologic changes were examined.Histopathologic changes after radiation.RESULTS: Since the third day, the ingestion and drinking amount of irradiated rats were decreased. The general activities were increased for the first two days, but decreased without abnormal nervous signs on the 3rd day. The rats in experimental group had a slower weight gain than those of control group, and the difference between them was of no statistical significance. All rats had slight alopecia and neuronal necrosis 2 weeks after irradiation.CONCLUSION: The irradiation method is reliable, practical and good for modeling REP process, which can be used in preventing or reducing the harm effect of radiation therapy on brain tissue.

Objective To evaluate the anatomic changes and dosimetric variations of patients with nasopharyngeal carcinoma (NPC) during the course of simultaneous integrated boost intensity-modulated radiotherapy (SIB-IMRT) by comparison of the dosimetric differences with or without replanning.Methods Twelve cases with NPC treated with SIB-IMRT underwent repeated CT scans after 20- 25 fractions of the initiation of therapy.The original treatment plan ( Plan1 ) based on the first CT scan ( CT1 ) and the second IMRT plan (Plan 2) based on the second CT scan (CT2) were calculated with an inverse planning system (Pinnacle3,Philips Medical System).In addition,the hybrid IMRT plan,Planl (CT2),was generated by deformable registration with MIMVISTA software,and the doses in Plan 1 ( CT1 ) and Plan 2 ( CT2 ) were accumulated based on CT2.The dosimetric differences were compared among the Plan 1 ( CT1 ),Plan 1 (CT2) and Plan 1 + 2(CT2).Results Compared with CT1,the mean volumes of the right and left parotid glands in the CT2 were significantly smaller by ( 24.6 ± 11.9 ) ％ and ( 35.1 ± 20.1 ) ％,respectively.Compared with Plan 1 ( CT1 ),the dose received by 95％ of the target ( D9s ) to PGTV,PTV1 and PTV2,and mean dose (D ) to PGTV,and PTV2 were all significantly lower in the Plan 1 (CT2),indicating that the doses to targets decreased without replanning.With repeated CT and replanning after 25 fractions as shown in Plan 1 + 2 (CT2),the doses to targets would be improved.The doses to normal tissue were increased without replanning,although no statistical significance was observed.In 5 of 12 cases,the doses to the spinal cord and brainstem exceeded the constraint without replanning,while the corresponding values decreased with replanning.Conclusions During the course of IMRT for cases with NPC,the volumes of the targets and parotid glands decrease significantly.Mid-treatment CT scanning and replanning should be recommended to ensure adequate doses to the targets and safe doses to the normal tissues.
