Objective To explore value of multidisciplinary team (MDT) model in diagnosis and treatment of patients with advanced special thyroid cancer who lost chance of operation. Method Two patients with the advanced special thyroid cancer who lost chance of operation were treated by low dose apatinib (250 mg/d) after the MDT discussion. Results One medullary thyroid cancer patient with the compressing of the trachea for mediastinal metastatic lymphadenopathy and inability to lie down underwent the multiple surgical treatment, the therapeutic effect was poor. Then low dose apatinib (250 mg/d) was performed, the patient could supine, breathe smoothly, and move freely, whose life quality was obviously improved, the mediastinal lymph nodes reduced and no serious drug toxicity occurred on month 1 after the treatment. One undifferentiated thyroid cancer patient with the lung metastasis, hemoptysis, and tumor invasion resulted in the inability to lie down and having difficulty in breathing, these symptoms still existed and more pleural effusion occurred after the resection of the invaded trachea. Then low dose apatinib (250 mg/d) was performed, the patient could supine, the pleural effusion disappeared, the hemoptysis stopped, the breathing was smooth, and could do some minor housework, no drug toxicity occurred on month 1 after the treatment. Conclusion After MDT discussion, low dose apatinib in treatment of advanced special thyroid cancer is reliable and safe and has a good short-term effect, which could be used as a new remedy, but long-term effect should be further researched by increasing case samples and a long-term following-up.
Objective To evaluate safty and effects of a single photodynamic therapy(PDT) for circumscribed choroid hemangiomas. Methods We performed a retrospective analysis of 11 eyes of 10 patients who were reated with single standard PDT. Of 10 patients, 6 males, 4 females；mean 40 .2 years old；of 11 eyes, 6 left eyes, 5 right eyes; 1 patient who both eyes wer e involved. Follow-up time varied from 1month to 14months, mean 6.2 month. Results After treatment, all tumors show various degrees of regression and subretinal fluid were absorbed completely or partly. The visual acuity of 8 eyes improved; that of 3 eyes unchanged. Conclusions PDT is effective modality for circumscribed choroid hemangiomas. (Chin J Ocul Fundus Dis,2008,24:111-113)
ObjectiveTo explore the effects of small dose and low pressure lavage on gastrointestinal hemorrhage induced by acute poisoning. MethodsWe collected the clinical data of all the patients diagnosed as gastrointestinal hemorrhage induced by acute poisoning treated between January 2011 and December 2012. The patients were divided into two groups: control group and treatment group, according to the different treatments they underwent. The control group received traditional treatment only, while the treatment group received small dose and low pressure lavage as well as the traditional treatment. After recording the ages, poisoning dose, pretreatment time, shock and complications, we evaluated the risk of death by calculating ROCKALL scores. ResultsThe differences of ages, sexes, and poisoning dose between these two groups were not significant. However, the death rate in high and middle risk patients of the treatment group was significantly lower than that of the control group (P<0.05). ConclusionThe small dose and low pressure lavage can improve the prognosis of the gastrointestinal hemorrhage induced by acute intoxication.
OBJECTIVE: To evaluate the effect of low-dose aspirin on the deposition of platelet at the anastomotic site and the function of coagulation system in order to provide experimental data for clinical use. METHODS: (1) Twenty-eight SD rats were divided into experimental group (n = 21) and control group (n = 7), aspirin were administered through a catheter placed in the femoral vein in dose of 4 mg/kg in the experimental group and the same dose of normal saline in the control group. The experimental group was subdivided into 3 groups, with 7 rats in each group, according to survival time of 24, 48 and 72 hours after dose. Samples of 4 ml blood were taken by heart puncture from each rat to investigate the maximal platelet aggregation rate(MAR), prothrombin time(PT) and kaolin partial thromboplastin time(KPTT). (2) Sixteen New Zealand White rabbits were divided into experimental and control group, 8 rabbits in each group. Drugs were given in the same way. Forty-eight hours later, the bilateral femoral arteries of each rabbit were exposed and arteries between inguinal ligament and the origin of the superficial epigastric arteries were transected and end-to-end anastomosis was completed with interrupted suturing technique. Fifteen and 120 minutes after the recovery of blood flow, the left and the right vessels containing anastomotic sites were harvested respectively and treated with 125I-labeled anti-GP IIb/III a antibody (SZ-21) using radioimmunobinding method. The radioactivities of the anastomosed vessels were measured. RESULTS: The KPTT in the experimental group was longer than that of the control group at 24- and 48-hour group, the mean percentages of increase were 42.56% and 35.33% respectively, and there were very significant differences between the experimental and control group in 24-hour group (P lt; 0.001). The PT value in experimental group was longer than that of the control group, but there was no significant difference (P gt; 0.05), and the maximal aggregation rate of platelet in the experimental group was significantly lower than that of the control group after 72 hours (P lt; 0.001). The radioactivity of the anastomosed arteries in the experimental group were significantly higher than that of the control group (P lt; 0.001) at 15 minutes after the recovery of blood flow, the mean percentage of increase was 110%. CONCLUSION: Low-dose aspirin can significantly affect the function of the intrinsic coagulation system, prevent the aggregation of platelets, but no effect on the function of the extrinsic coagulation system. On the other hand, it can also increase the deposition of platelet on the anastomotic sites after end-to-end anastomosis, especially in the early stage when it is intravenously injected, but it is b enough to cause thrombosis at the anastomotic sites. The effects of low dose aspirin on the coagulation system are inconsistent with its local effects on anastomotic sites.
Objective To systematically evaluate the effectiveness of N-acetylcysteine (NAC) combined with low-dose glucocorticoid for patients with idiopathic pulmonary fibrosis (IPF). Methods Such databases as The Cochrane Library (Issue 12, 2012), EMbase (January 1974 to July 2012), PubMed (January 1966 to July 2012), CHEST (January 1995 to July 2012), CNKI (January 1994 to July 2012), CBM (January 1978 to July 2012), VIP (January 1989 to July 2012) and WanFang Data (January 1995 to July 2012) were searched to collect the randomized controlled trials (RCTs) about NAC combined with low-dose glucocorticoid versus glucocorticoid alone for IPF patients. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and assessed the quality, and then the meta-analysis was performed using RevMan 5.1 software. Results A total of seven RCTs including 264 IPF patients were included. The results of meta-analysis demonstrated that, compared with the glucocorticoid used alone, a) NAC combined with low-dose glucocorticoid could significantly improve PaO2 (SMD=0.82 mmHg, 95%CI 0.30 to 1.35, P=0.002) and DLco (SMD=0.59 mmHg, 95%CI 0.16 to 1.03, P=0.008) with a significant difference. b) NAC combined with low-dose glucocorticoid could significantly improve all clinical symptoms (RR=1.56, 95%CI 1.26 to 1.92, Plt;0.000 1). Conclusion NAC combined with low-dose glucocorticoid for IPF patients can significantly improve PaO2, DLco, and the clinical symptoms such as cough, difficulty breathing after activities, cyanosis, and Velcro rales. Due to the quantity and quality limitation of included studies, this conclusion still needs to be further proved by more high quality and double blind RCTs.
