Large cell neuroendocrine lung cancer（LCNEC） is the rare subtype of nonsmall cell lung cancer. Because of its low incidence rate and the special biological behaviour, it is hard to define in pathology. And we also know little about its epidemiological feature and the purposeful therapy view of LCNEC, and the therapeutic effect is unsatisfactory. This article will review and introduce the advance of research, clinical diagnosis and therapeutic of the LCNEC.
ObjectiveTo discuss the indication, therapeutic effect, complication of endoscopic surgery for pancreatic pseudocyst and its defect and merit.MethodsThe pertinent literatures about pancreatic pseudocyst treated by endoscopic technique were summarized. ResultsEndoscopic technique possessed the peculiarities of less trauma, convenience to operate and could be repeatedly used. The number of patients with pancreatic pseudocyst suitable for endoscopic therapy was increasing. When pancreatic pseudocyst was accompanied with complication, polycystic or failed in endoscopic treatment, surgical intervention was the only choice. Endoscopic technique would be considered firstly in other conditions.ConclusionIndividual scheme should be advocated according to the size, number location and complication of the pancreatic pseudocyst.
【Abstract】Objective To study the change of pancreatic microcirculation in the early phase of acute pancreatitis. MethodsLiteratures on acute pancreatitis and microcirculation were collected and reviewed.ResultsPancreatic microcirculation has changed in the early phase of acute pancreatitis, including contraction of interlobular arteriole, slowing of blood fluid, increasing of pancreatic vascular permeability, leukocyte adherence in postcapillary venules, and decreasing of pancreatic perfusion.Conclusion Impairment of pancreatic microcirculation in the early phase of acute pancreatitis may play a key role in the progression of this disease.

【Abstract】Objective To investigate the role of early surgical intervention in the treatment of fulminant acute pancreatitis (FAP).Methods Eight cases of FAP admitted to our institution from September 2003 to December 2004 were reviewed retrospectively.Results Averagely 3 organs dysfunction was diagnosed on admission or in the course of treatment in this group. One patient treated non-operatively was dead. Of 7 cases with early surgical intervention, one was died of ACS and ARF, One female patient with 32 weeks pregnancy survived, but the fetus was dead before surgery. Five cases were complicated with intra-abscess, which were cured re-operatively. Conclusion Early operative intervention in the treatment of FAP could prevent MODS and improve the survival.
Objective To evaluate the effect of vascular endothelial growth factor (VEGF) on tumor angiogenesis, and its usage in tumor therapy.Methods The recent literatures about VEGF and angiogenesis were reviewed and analyzed. The advances of VEGF study were summarized. The effects of anti-angiogenesis in tumor biological therapy were introduced.Results Angiogenesis had been identified as an important factor for promoting tumor growth. VEGF was a basic and pivotal factor in tumor angiogenesis. The anti-angiogenesis treatments aimed at VEGF, including the applications of VEGF inhibitor and gene therapy of adenovirus medium, had got great progress. Conclusion VEGF is a leading factor of tumor angiogenesis, the anti-angiogenesis therapy aimed at VEGF has probably provided a new chance to malignant tumor treatment.
ObjectiveTo sum up the diagnosis and treatment of adult ileal duplication with clinical cases from Peking Union Medical College Hospital (PUMCH). MethodsSix cases of adult ileal duplication admitted in our hospital from February 1996 to December 2010 were analyzed. Different assistant investigations were supposed to different patients due to the chief complaints including gastroscope, colonoscopy, abdominal CT scan, arteriography, 99Tcm radionuclide imaging, and double-balloon intestinal endoscope. None was made a definite diagnosis before operation with only one uncertain case. All cases received operation and pathological examination. Results All cases admitted were male. The chief complaints included intestinal bleeding, abdominalgia, intestinal obstruction, and abdominal mass. Five out of six patients received gastroscope, colonoscopy, and abdominal CT scan while three received mesenteric arteriography, but none was found any suggestion for ileal duplication. Even 99Tcm radionuclide imaging pointed out only two with abnormal abdominal bleeding. Three received doubleballoon intestinal endoscope, paying attention that only one discovered with ileal duplication. In a concluding, none was made a definite diagnosis before operation with only one uncertain case. All the cases received operation. The duplications of ileum in the length of 6-25 cm were found at the site of 11-100 cm proximal to ileocecum during the operation. Pathological report confirmed the clinical diagnosis of all cases with adult ileal duplications． Two cases were found with ectopic gastric mucosa, another two with diverticulum, and one with ectopic pancreas， in addition the remaining with inflammatory fibrous pseudotumor. Prognosis were good for all after operation. ConclusionsIleal duplications are rarely seen in adults, gender prefer male． Without specific clinical symptoms and inspections, definite diagnosis before operation is hard to make. But maybe doubleballoon intestinal endoscope and 99Tcm radionuclide imaging can give out positive result. Surgeons should be aware of this condition when performing abdominal exploration. Once discovered, resection is necessary.
Objective To evaluate the efficacy of Budesonide / formoterol to control asthma under real-life conditions. Methods A multi-center, open label, non-interventional study was conducted. Asthma control after 12 week therapy with Budesonide/ formoterol was assessed by Asthma Control Questionnaire( ACQ) and modified Asthma Control Questionnaire ( ACQ5) . Results A total of 360 asthma patients were recruited, including 228 adult patients and 132 child patients. After 12 weeks’ therapy, all the patients’medium value of ACQ was decreased significantly from 2. 03 ( adults 2. 20, children 1. 74) at baseline to 0. 60 ( adults 0. 78, children 0. 29) ( P lt; 0. 0001 ) , and the medium value of ACQ5 was also decreased significantly from2. 4 ( adults 2. 24, children 1. 76) at baseline to 0. 47 ( adults 0. 62, children 0. 20) ( P lt;0. 0001) . Conclusion Budesonide / formoterol is effective in asthma treatment, by which most asthma patients obtain and maintain clincal control.
Abstract: Objective To investigate the clinical characteristics of thymoma and thymoma with myasthenia gravis(MG). Methods From Oct.1979 to July 2004,185 patients with thymoma were surgically treated. Among these patients, comparative analysis was made between 94 cases of thymoma (thymoma group) and 91 cases of thymus tumor with MG(thymoma with MG group).155 patients underwent radical operation (83.8%),16 patients underwent palliative operation (8.6%),and 14 patients underwent exploratory operation (7.6%). Clinical characteristics was analyzed in two groups. The factors affecting prognosis was analyzed by Masaoka’s stage system, with the lifttable method. Results Five patients died after operation, others had complete remission or symptomatic improvement. There was statistically difference of Masaoka’s stage system in two groups (χ2=53.14, P＜0.05). There were no statistically difference in pathological type of thymoma and clinical type of MG and pathologic period (χ2=8.21, P＞0.05). 57 cases of thymoma group were followed up, the duration of follow-up was 1 to 10 years, average follow-up was 40.7 months, and the patients with 1-, 3- and 5-year survival rates were 70.2% (40/57), 66.7% (22/33), 593% (16/27) respectively. 55 cases of thymoma with MG group were followed up. The patients’ survival rates were 98.2% (54/55), 86.4% (38/44), 81.6% (31/38) at 1-, 3-and 5-year respectively. There was no statistically difference of survival rates in two groups (χ2=0.83, P＞0.05). Totally, 112 patients were followed up in two groups, by Masaoka’s stage system, the 5-year survival rates were 93.7% for stage Ⅰ, 79.2% for stageⅡ, 51.4% for stage Ⅲ and 0% for stage Ⅳ respectively. Result of asaoka’s stage system evidence was statistically significant (χ25-year=51.62, P＜0.01). Conclusions Pathological type of thymoma isn’t related to modified Osserman’s classification, prognosis of thymoma is obviously related to Masaoka’s stage and isn’t related to MG. Generalized MG is the major type in MG patients accompanied by thymomas, and the major pathological type is lymphocytic. Chest CT can increase the accuracy early diagnosis of thymoma. The principal treatment is to resect the tumor as completely as possible, and proper administration of postoperative radiotherapy or chemotherapy according to the surgical status. Operative program and tumor stage are the most important prognostic factors.
Objectives To assess the effectiveness and safety of any form of therapy compared with glucocorticoid for the treatment of oral lichen planus. Method The Cochrane Library (Issue 4, 2007), MEDLINE (1966-2007), EMbase (1966-2007), CBM (1978-2005), CNKI (1989-2007), and VIP (1989-2007) were searched for randomized controlled trials or quasi-randomized controlled trials. Quality assessment and data extraction were performed by two reviewers independently. Meta-analysis was performed for the results of homogeneous studies by RevMan 4.2.9 software.Results Finally, 14 studies involving 9 therapy methods were included. Four studies were concerned with cyclosporine.We performed a meta-analysis of 3 studies. The results showed there was no statistically significant difference in the curative effect of cyclosporine and the steroid with RR 2.94 and 95%CI 1.03 to 9.97. The results showed that the curative effect of total glucosides of paenia plus topical application of triamcinolone acetonide (RR0.21, 95%CI 0.10 to 0.44),tacrolimu (RR 0.18 and 95%CI 0.05 to 0.72), and pimecrolimus (WMD –0.50 and 95%CI –0.85 to –0.15) were better than glucocorticoid. There was a statistically significant difference between fluocinolone acetonide and retinoic acid in terms of curative effect with RR 3.20 and 95%CI 1.03 to 9.97. The curative effect of mesalazine (RR 0.42 and 95%CI 0.05 to 3.54), Mycostatin paste plus desamethasone paste (RR 1.23 and 95%CI 0.93 to 1.61), triamcinolone acetonide plus vitamin B12 ( RR 0.50 and 95%CI 0.05 to 4.94), chitin (RR 1.30 and 95%CI 0.86 to 1.96) was similar with that of glucocorticoid.Conclusion Statistical analysis showed the curative effect of total glucosides of paenia combined with triamcinoloneacetonide is better than glucocorticoid. Due to the mistakes of theincluded studies designs,,further high-quality,largescale randomized controlled trials are required to confirm the effectiveness and safety of this therapy method.
