Taking galactophore X-ray with Axial and Oblique positions firstly, then having laser films taken by the post-processor of CR system.Results: Of the 45 case,20 cases were diagnosed bengin diseases,and 25 cases were malignant tumor,the accuracy of CR system was 90% as compared with postoperative pathologic diagnosis.Conclusion: CR technology plays an outstanding role in aspects of diagnosis, differentiating diagnosis, discovering tumour in early stage.

Objective To evaluate the value of echocardiography in patients with isolated anomalous origin of right pulmonary artery from ascending aorta. Methods The eehoeardiographie results of five patients with isolated anomalous origin of right pulmonary artery from ascending aorta were reviewed retrospectively. Results Severe pulmonary hypertension occurred in all the patients,besides accompanied with patent duetus arterious, no other congenital malformations combined. Three patients underwent operation. Patent ductus arterious was missed in one patient's diagnosis. Another patient was missed isolated anomalous origin of right pulmonary artery from ascending aorta in several echoeardiographic examinations, once misdiagnosed as complete transposition of the great arteries. Conclusions There are many anatomic and hemodynamic similarities in patients with isolated anomalous origin of right pulmonary artery from ascending aorta. Grasping their common charaeters and exploring multi-position and multi-section are helpful to make correct diagnosis.

ObjectiveTo explore the effects of nutritional intervention and individualized nursing on nutritional risk, undernutrition and quality of life (QOL) in end-stage renal disease (ESRD) patients with peritoneal dialysis. MethodsA total of 104 ESRD patients with peritoneal dialysis who met the inclusion criteria of the protocol were enrolled and randomized to receive nutritional intervention plus individualized nursing ( study group, n =52 analyzed) or self-diet plus routine nursing ( control group, n =50 analyzed) for 6 months. Nutritional risk, anthropometry, and QOL of the two groups were analyzed pre- and post-nutritional intervention. ResultsBaseline data were comparable in the two groups. Prevalences of nutritional risk and undernutrition in study group were significant lower than those in control group after the intervention ( nutritional risk: 32.6％ vs. 56.0％, P =0.028 ;undernutrition: 15.4％ vs. 34.0％, P =0.038). The decrease of grip strength in study group between pre- and post-study was significantly less than that in control group [( - 1.6 ± 0.9 ) kg vs. ( - 9.9 ± 1.4 ) kg, P =0.001], but there were no significant differences in other parameters related to anthropometry, including triceps skin-fold thickness, upper arm circumference, and arm muscle circumference ( all P ＞ 0.05 ). The QOL score significantly increased in study group after intervention but decreased in control group. The differences of renal disease and dialysis-related scores ( △KDTA: 2.5 ± 4.4 vs.- 7.9 ± 7.4, P =0.001 ) and general condition scores (△SF-36 : 3.4 ±4.1 vs.- 6.8 ± 6.3, P =0.001 ) before and after intervention were significantly different between two groups. ConclusionNutrition intervention and individualized nursing may help to improve the nutritional status and QOL in ESRD patients with peritoneal dialysis.

Objective:To clarify the effects of the BMP receptor inhibitor LDN-193189 in the dedifferentiated chondrosarcoma (DDCS) cell line NDCS-1 and to explore the anti-tumor mechanism of LDN-193189 in DDCS. Methods:NDCS-1 was treated with 5 nmol/L of LDN-193189. MTT assay and clone formation experiments were used to verify that LDN-193189 suppressed cel proliferation. Transwel and wound healing tests were performed to demonstrate that LDN-193189 inhibited cell invasion. Western blot detection was used to show that LDN-193189 inhibited the suppression of BMPR2, p-Smad1/5, and RUNX2 protein expression. Results:The BMPR2 signaling pathway was inhibited by LDN-193189;thus, cell viability and invasion were significantly suppressed. Conclusion:LDN-193189 induces the inhibition of progression in vitro via the BMPR2-p-Smad1/5-RUNX2 signaling pathway in the human DDCS cell line NDCS-1.

Objectives: This prospective,randomized and controlled clinical trial was designed to investigate the effect of short course intensive insulin therapy(SCIIT) on stress-induced hyperglycemia and outcomes in critically ill patient. Methods:The diabetes or other illness which directly influenced blood glucose were excluded and the critically ill patients was maintained with normoglycemia((4.4-6.1) mmol/L) in the first seven days by intensive insulin therapy.After the first seven days,these patients was treated like conventional insulin treatment group.Conventional insulin treatment group was maintained with blood glucose at a level between 3.9-10 mmol/L.Results: Of 41 patients enrolled in the study,30 patients were eligible for analysis.After intervention stopped,blood glucose level in intensive insulin treatment group(5.92?1.24 mmol/L) was lower than in conventional insulin treatment group((9.22?)2.51 mmol/L).And in the same time,insulin consumptions in SCIIT group was lower than in conventional insulin treatment group.There was no significant difference in ICU mortality between two groups,although decreasing trend favored to treatment group. Conclusion: In critical ill patient,(SCIIT) can achieve similar blood glucose range when compared with the plan of IIT.The benefit of improving morbidity and mortality could be expected in large sample RCTs.

High mobility group box chromosomal protein (HMGB1), an abundant eukaryotic nonhistone chromosomal protein, is previously known as a nuclear DNA-binding protein that stabilizes the structure and function of chromatin, regulates gene transcription. Recent studies identify that extracellular HMGB1 as a late mediator of endotoxemia and sepsis.HMGB1 is released by activated macrophages,induces the release of other proinflammatory mediators,and mediates lethality when overexpressed. It may also be a key signal for eliciting immune responses to cellular injury and death.Moreover,the late kinetics of HMGB1,in compared with other proinflammatory cytokines such as TNF and IL-1,suggest that targeting HMGB1 may provide a wide and clinically accessible therapeutic window.Three independent strategies to inhibit HMGB1 release and action are now available:anti-HMGB1 antibodies,A box,and ethyl pyruvate. This review covers the general features of HMGB1 and progress in research on its newly role as a cytokine participating in the development of sepsis.

Purpose: To observe the efficacy and the side effects of oxaliplatin( OXA) in combination with vinorelbine (VRB) in the treatment of drug resistant non-small-cell lung cancer( NSCLC) . Methodii: Thirty-five patients with drug resistant lung cancer were treated by OXA + VRB. OXA 100 mg/m2, VRB 25 mg/m , on d 1, which were given by bronchial arteries injection, and VRB 25mg/m2 was given by venous injection on d 8. One cycle was given every 3 weeks and total six cycles was given. Results: There was 1 patient who showed completed remission( CR), 14 patients showed partial remission( PR), 13 patients showed stable disease( SD) and 7 patients showed progress disease( PD) after the sixth cycle. The response rate was 42. 9%. The major toxicities were peripheral sensory neuropathy and leukopenia. Conclusions: The regimen of OXA plus VRB is effective on drug resistant and advanced NSCLC and the side effects are tolerable. There is higher response rate and lower neurotoxicity when the medicines are given by arterial injection than by venous injection.
