Objective To evaluate the efficacy of radiation therapy on primary vaginal cancer with high dose rate brachytherapy alone or in combination with external radiation Methods Fifty one cases with primary vaginal cancer who were treated with high dose rate brachytherapy alone or in combination with the external radiation in Cancer Hospital, Chinese Academy of Medical Sciences from 1989 to 1999 were retrospectively studied,including stage Ⅰ 10 cases,stage Ⅱ 13 cases,stage Ⅲ 23 cases and stage Ⅳ 5 cases WD HDR18 after loading equipment was used in the brachytherapy and 6 or 8 MV linear accelerator was used in the external radiation Results The overall 5 year survival rate with WD HDR18 was 58 8%, with 80 0% for stage Ⅰ,76 9% for stage Ⅱ,65 2% for stage Ⅲ,and 0 0% for stage Ⅳ The comparison of treatments with WD HDR18 and radium therapy showed the 5 year survival rates of the cases of each stage treated with WD HDR18 were higher Conclusion Treatment results obtained with high dose rate brachytherapy are at least similar to traditional radium therapy for primary vaginal cancer

Theory of Shen-Xu Pang-Guang-Re (SXPGR) is an important part of the theory of zang-fu in traditional Chinese medicine (TCM). And it is the generalization for etiology and pathogenesis of Lin-Zheng (LZ). In immunology, mucosal immune system is composed of mucosal-associated lymphoid tissues and immune cells, which can resist the invasion of microorganisms. Mucosal immune plays an important role in the occurrence of urinary tract infection. This paper, which was based on SIgA and homing mechanism, was to investigate the relevance between mucosal immunity and the theory of SXPGR, in order to study the connotation of SXPGR in TCM.

Objective To investigate the accuracy of end-tidal carbon dioxide (PETCO2) in reflecting arterial carbon dioxide (PaCO2) during mechanical ventilation via laryngeal mask airway (LMA) in children. Methods Fifty-two ASA Ⅰ patients, aged 2-9 yr, weighing 10-30 kg, undergoing orthopaedic surgery under general anesthesia, were randomized into 2 groups (n = 26 each) : LMA group and endotracheal tube (ETT) group. After anesthesia was induced with fentanyl, propofol and succinycholine, LMA or ETT was inserted and the children were mechanically ventilated. After the hemodynamics was stable, arterial blood samples were obtained to detect PaCO2, and PETCO2 was recorded simultaneously. Results There was no significant difference in PaCO2 and PCT CO, between groups LMA and ETT ( P ＞ 0.05) . There was no significant difference between PaCO2 and PETCO2 in LMA group (P ＞ 0.05). Conclusion When mechanical ventilation is performed via LMA in children, PETCO2 can reliably reflect PaCO2 and guide the regulation of ventilatory parameters.

Objective To investigate the effect of partial liquid ventilation(PLV) with perfluorocarbon(PFC) on pulmonary surfactant during beatment of acute lung injury(ALI) induced by oleic acid. MethodsTwenty-four male Japanese white rabbits weighing 2. 1-2.6 kg were randomly divided into three groups(n = 8 ineach group): groupl: normal animal + mechanical ventilation (MV); group 2: ALI + MV; group 3: ALI +PLV.The animals were anesthetized with intraperitoneal ketamine 100 mg/kg, trachectomized and mechanicallyventilated (FiO_2 = 1, RR = 35 bpm, I: E = 1: 2, PEEP = 5 cm H_2O, PaCO_2 was maintained at 35-45 mm Hg byadjustment of tidal volume) .In group 2 and 3 ALI was induced by infusion of oleic acid 150?g/kg via centralvenous catheter over 30 min period. ALI was considered established when PaO_2 /FiO_2 was

0 05) The parameters did not change significantly with increasing MAC in group D, whereas LESP, BrP and PVV decreased significantly in a dose dependent manner in group E (P

Objective To investigate the effects of filter placement for inferior vena cava in prevention of fatal pulmonary embolism(PE)and the treatment of postoperative complications. Methods Inferior vena cava filters were placed in 96 patients by the way of femoral vein. Results All the patients were followed up for 4 - 36 months after the procedure without fatal pulmonary embolism occurrance in the 96 patients, but with only 17 correlated complications. Conclusion Inferior vena cava filter placement is easy and safe which can prevent the high complication incidence of fatal pulmonary arterial embolism with further more effective prevention and management of other correlative complications.

Objective To study the influence of interim overload exercise on health and it's biochemical mechanism.Methods 45 Wistar rats were randomly divided to three groups(n=15):no exercises group(control,C),normal exercise group(NE,the rats ran in the animal running machines at 15 m?min-1for 5 d in one week,exercise time was 30 min?2,and rested for 10 min after ran for 30 min),overload exercise group(OE,the rats exercised 2 bouts,2 d in consecutive in one week,exercise time was 100 min?2,and they rested for 10 min after ran for 100 min).After training for 8 weeks,the rats in three groups were sacrificed and 15 biochemical indexes in blood of rats were determined.Results Compared with C and NE groups,CK,LDH,and ALT increased obviously(P

Objective To evaluate the feasibility of autologous mononuclear bone marrow cells (BMCs) transplantation in patients with anterior myocardial infarction. Methods Twenty-two patients were enrolled in this prospective, nonrandomized, control study (14 patients in cell transplantation group; 8 in control group). All patients underwent standard percutaneous coronary intervention (PCI) and drug therapy. 14 patients in the cell transplantation group were transplanted with autologous mononuclear (BMCs) via a over-the-wire (OTW) balloon catheter slowly placed into the left anterior descending (LAD) coronary artery during inflation. Results One patient in the cell transplantation group died of acute drug eluting stent thrombosis. The other 13 patients and the 8 patients in the control group had no procedure related complications and ventricular arrhythmia. All patients in both groups underwent 3-month and 6-month follow-up, 6 minutes test, 2D Doppler echocardiogram, single photon emission computed tomography and cardiac magnetic resonance imaging (MRI). After 3 months of follow-up, a significant increase of left ventricular ejection fraction (LVEF) determined by ultrasonic cardiography was found [(50.37?7.31)% vs (40.12?5.52)% before transplantation, P =0.000?1] and was also significantly greater compared with the control group [(50.37?7.31)% vs (44.09?3.50)%, P =0.035]. Conclusion The result indicates that selective intracoronary transplantation of autologous mononuclear BMCs seems to be feasible and may improve the left ventricular systolic function.

Objective To observe the clinical effect of Zhang point in subclavian vein puncture. Methods One hundred patients underwent deep vein catheterization were selected, ASA grade of Ⅱ- Ⅲ. The patients were divided into 2 groups according to puncture method with 50 cases each, the patients in group A used traditional puncturing method, and the patients in group B used Zhang point puncture method. The total success rate, success rate of the first trial and incidence of complication were recorded. All the patients received the bedside chest X-ray examination to observe the location of central venous catheter after surgery. Results The total success rate and success rate of the first trial in group B were significantly higher than those in group A:100%(50/50) vs. 88%(44/50) and 96%(48/50) vs. 76%(38/50), the incidence of complication was significantly lower than that in group A: 4% (2/50) vs. 20%(10/50), there were statistical differences (P<0.05). Conclusions Using of Zhang point is very simple in subclavian vein puncture catheterization, with a higher success rate and a less complication rate.

Interleukin 24(IL 24),also called the melanoma differentiation associated gene 7(MDA 7),is stably expressed in human tissues associated with the immune system such as the spleen,thymus,peripheral blood leukocytes and normal melanocytes. IL 24 binds to IL 20 and IL 22 receptor complexes(IL 22R1/IL 20R2 and IL 20R1/IL 20R2),and induces secretion of high levels of IL 6,TNF alpha,and IFN gamma and low levels of IL 1beta,IL 12,and GM CSF from human PBMC. Adenoviral IL 24(Ad IL 24) induces growth suppression and apoptosis selectively in diverse human cancers and tumor cell lines without producing any apparent harmful effect in normal cells. The effects of Ad IL 24 are associated to the ratio of pro apoptotic(BAX,BAK) to anti apoptotic(Bcl 2) proteins,and the up regulation of p38 MAPK and a family of growth arrest and DNA damage(GADD) inducible genes. These demonstrate the potential therapeutic effects of Ad IL 24 in human cancer.
