Objective To evaluate the effect of intratumor injection of Pingyangmycin for the treatment of superficial hemangioma and venous malformation.Methods From May 2005 to March 2008,42 patients with superficial hemangioma or venous malformation,including 17 men and 25 women(aged 3 months to 51 years)were treated in our hospital by injecting pingyangmycin intratumorally.Among the patients,18 had hemangioma,20 had venous malformation,and 4 had the both.The injection consisted of a mixture of Pingyangmycin(8 mg),2% lidocaine(2 ml),normal saline(2 ml),and dexamethasone(2.5 mg).The volume of the tumor was evaluated before the injection.And then the mixture was injected intratumorally at a density of 0.5 mg/cm2(0.3 mg/cm2 for the patients with ulcers in the skin or mouth).For the patients who had residual tumor after the first injection,a second treatment was performed in 10 days to 3 weeks or longer.The maximum dosage of Pingyangmycin for a single injection was 8 mg,and the maximum total dosage was 70 mg.Results One year after the treatment,85.5%(47/55)of the patients were cured,and 12.7%(7/55)were improved.The total effective rate was 98.2%(54/55).Conclusions Injection of Pingyangmycin is an effective and safe method for superficial hemangioma and venous malformation with low blood flow.The maximum injection density is 0.5mg/cm2.

Objective To assess the benefit of intraoperatively placed nasointestinal feeding tubes for early postoperative enteral nutrition.Methods The retrospective study was carried out on 19 cases of in-fants with long gap esophageal atresia who underwent one-stage operation in Xinhua Hospital from January 2006 to December 2013.Patients were divided into two groups according to whether the transanastomotic na-sointestinal feeding tubes(TNFT)were placed.Demographics,associated anomalies,operative findings,com-plications,duration of enteral nutrition(EN),length of stay were analyzed.Results Thirty-seven patients had long gap esophageal atresia and nineteen underwent one-stage operation.Eight patients were identified as TNFT group while eleven patients were identified as nonfeeding tube(NFT)group.There was no significant differences between the two groups in gestational age,birth weight,associated anomalies,anastomotic leak, weight gain,ICU-free days and length of stay(P>0.05).But the ventilator-free days(23.5 d vs.19.3 d), first EN time(0.8 d vs.9.1 d)and total EN feeding time(15.9 d vs.21.4 d)between the two groups were significantly different(P<0.05 ).Conclusion Intraoperatively placed TNFT may lead to earlier EN feeding and shorter parenteral nutrition duration,but a larger prospective study would be required to prove the benefits and ensure the safety.

Objective To investigate the comprehensive prevention strategy in the prevention of oral mucositis (OM) during allogeneic hematopoietic stem cell transplantation (HSCT). Methods A total of 721 patients who received HSCT from January 2010 to December 2011 at the Institute of Hematology, Peking University were enrolled. All the patients received the comprehensive prevention strategy of OM. Results A total of 315 patients (43.7 percents) suffered from OM during HSCT, the median time from HSCT to OM occurrence was 5 days. There were 173 (54.9 percents), 91(28.9 percents), 37(11.7 percents), and 14(4.4 percents) patients suffered from gradeⅠ,Ⅱ,Ⅲ, and IV OM, respectively. Tongue OM was most common. A total of 111 patients suffered from multiple OM (≥2 locations). Multiplicity showed that duration of agranulocytosis≥15 days was the only independent risk factor of OM in HSCT [ hazard ratio (HR) value 1.5, P<0.05 ]. Neutrophil engraftment time≥12 days was significantly associated with prolonged OM (≥8 days) (HR=2.1, P<0.05). Patient age ≥20 was independent risk factor for occurrance of grade Ⅲ-Ⅳ OM (HR=2.7, P<0.05). Conclusions Comprehensive prevention strategy can overcome the risk factors of OM and prevent the occurrence of OM during HSCT.

Objective To investigate the expression of p-MNK1 in non-small cell lung cancer and its relationship with clinic pathological features and prognosis.Methods The level of p-MNK1 in 115 cases of nonsmall cell lung cancer was detected by tissue microarray technique and immunohistochemistry technique.Results The level of p-MNK 1 in non-small cell lung cancer was correlated with cancer tissue type (P ＜ 0.05),clinical stage (P ＜ 0.05),lymph node metastasis (P ＜ 0.01) and prognosis (P ＜ 0.05).Cox multiple regression analysis showed that p-MNK1 expression was an independent prognostic factor for non-small cell lung cancer (P ＜ 0.01).Conclusion The level of p-MNK1 in non-small cell lung cancer is associated with poor prognosis.It can be used as an independent prognostic marker and a new therapeutic target.

OBJECTIVE To investigate the etiology of acute respiratory tract infection(ARI)in Hefei area and risk factors that may influence the distribution of common pathogens.METHODS Direct immunofluorescence assay was applied to detect the respiratory syncytial virus(RSV),adenovirus(ADV),influenza virus A(FluA),influenza virus B(FluB),parainfluenza virus PIV(1,2,3)and real time fluorescent quantitation polymerase chain reaction (FQ-PCR)was applied to measuring Mycoplasma pneumoniae(MP)and Chlamydia pneumoniae(CP)in nasopharyngeal secretions and sputum specimens.RESULTS Among 530 cases included in this study,421 cases (79.43%)showed positive viral etiology.ADV accounted for 73(13.77%),FluA-68(12.83%),FluB-56 (10.56%),RSV-48(9.05%),PIVl-47(8.86%),PIV3-42(7.92%),PIV2-33(6.22%),MP-32(6.03%)and CP-22(4.15%).The detected positive rate of pathogens isolated in winter was the highest(85.07%).CONCLUSIONS Acute upper respiratory tract infection(AURTI)is common and more than 75%pathogens in Hefei area are virus in which the most commonly virus is ADV.Meanwhile atypical pathogens of infection should not be ignored.

Objective To investigate the clinical and pathological characteristics of carcinoid tumor in rectum and its treatment. Methods The clinical and pathological data of 38 rectal carcinoid patients from Wuhan Center Hospital and Wuhan the Eighth Hospital from January 2005 to December 2009 and reviewed were analyzed retrospectively. Results All 38 cases were typical carcinoid, located in the rectum within 10 centimeters to the lower border of the anal canal.The classic characters were submuscosal tumor with yellow color and rigid or tough texture and always were lack of mobility. Carcinoid tumor of rectum often expressed markers of neuroendocrine differentiation on immunohistochemical staining.Among 38 cases, 34 cases were less than or equal to 2.0 cm in diameter and located in lamina propria (n=30) or invased submucosal layer (n=4), these patients were cured by endoscopic mucosal resection (EMR).Four cases were larger than 2.0 cm in diameter with muscularis externa invasion, treated by curative resection.All tumors <2.0 cm in diameter had a very lower Ki-67 labeling index (<3% ).34 patients survived at the latest follow-up. Conclusions The diagnosis of rectal carcinoid relies on histopathology and immunohistochemistry. The behavior of the rectal carcinoid shows low degree of malignant potentia. They rarely invade the muscularis externa or metastases. Most of them can be cured by endoscopic mucosal resection(EMR).
