Objective To investigate the safety and effectiveness of endoscopic resection of tumors originated from gastric fundus muscularis propria.Methods Data of 53 patients with tumors originated from gastric fundus muscularis propria detected by endoscopic ultrasonograpy,treated by endoscopic resection and followed up at our hospital between January 2012 and June 2014 were reviewed.The postoperative pathology and complications were retrospectively analyzed to evaluate the therapeutic effect and safety.Results The procedure was successfully performed on all patients and all lesions were removed in one procedure.The lesion size ranged from 0.5 to 4.5 cm and the operation time was 25-155 min[mean(46.7 ±18.2)min].Mild bleeding (5 ~150 ml)occurred in all cases,which was successfully managed by argon plasma coagulation,hot biopsy probe or endoclip.Perforation occurred in 8 patients(8 /53),seven of whom were closed with titanium clips and titanium clips combined with nylon cord.Laparoscopic intervention was applied to 1 case because of severe perforation.Gastrointestinal decompression,acid suppression with proton pump inhibitors and antibiotics were performed on all cases.No severe hemorrhage occurred.The average length of hospitalization was (5.3 ± 1.4)days(3-14 d).Pathology confirmed 46 cases of gastrointestinal stromal tumors and 7 cases of leiomyoma. The patients were followed up for 3 to 27 months,and no tumor residue or recurrence was observed. Conclusion Endoscopic resection is a method not only to get the accurate pathologic diagnosis but also to meet principle of the local resection for stomach.It is safe,effective and worthy of recommendation.

OBJECTIVETo investigate the main factors that influence measles morbidity and the genotype of measles virus, so as to provide evidence for scientific decision making to further control the prevalence of measles.

METHODA retrospective analysis included 182 children in Children's Hospital of Fudan University, diagnosed with measles from January 1, 2012 to December 31. The clinical and epidemiological characteristics, including the gender, age, the incidence of seasonal trends, measles vaccine vaccination history, contact history and other clinical manifestations, laboratory test results, and so on were analyzed. And the reverse transcription PCR (RT-PCR) was adopted to detect sputum specimens from suspected patients with measles,who were selected randomly,the sequence of the part of the PCR products was analyzed.

RESULT(1) Clinical and epidemiological data: Totally were 182 children with measles (125 males, 57 females) were enrolled into this study. The age of the patients ranged from 3 months to 89 months, 127 cases were younger than 9 months (69. 8%). The prevalence season was from April to August, while the peak month was April and May (22. 5%, 23. 1%). Among 182 hospitalized children, only 11 cases underwent measles vaccination (6. 0%), and among them 5 cases were within 2 weeks before disease onset. A total of 167 cases (91. 8%) had not been vaccinated, most of whom were immigrants, and the measles vaccination history of the remaining 4 cases were unknown. There was a positive correlation between the measles vaccination ratio in children of the floating population (8. 45%, 6/71) and the settled children (29.4%, 5/17, χ =8. 11 P =0. 004). In total, 24 cases (13. 2%) had definite measles exposure history, with 153 cases (84. 1%) of unknown origin,5 cases (2.7%) without any history of contact. (2) Clinical manifestations: All the 182 patients had fever (100%) and obvious rashes (100%), among them 145 cases had body temperature higher than 39 °C (79. 7%). The fever period ranged from 2 to 38 days. Among 182 hospitalized children,165 cases (90. 7%) had typical measles,17 cases had atypical measles. Among the 17 cases, two had severe measles, one had heterotypic measles. (3) The common complica tions: 96 cases had pneumonia (52. 8%), 80 had laryngitis (44. 0%), 38 had bronchitis (20. 9%),15 had hepatic dysfunction (8. 2%), 11 had myocardial damage (6. 0%), 3 had febrile seizures (1. 6%), and no patient had encephalitis. Of the 96 cases with pneumonia, 92 received sputum test; 38 were sputum culture positive (41%). The dominant pathogens were Streptococcus pneumoniae(11/38,29%), Haemophilus influenzae (6/ 38,16%), Moraxella catarrhalis (4/38, 11%), Escherichia coli (4/38, 11%), Candida albicans (4/38, 11%), Mycoplasma pneumoniae (4/38, 11%) and Staphylococcus aureus (3/38, 8%). (4) The H1a genotype was the only one genotype in the detected sequence of 54 measles virus strains.

CONCLUSIONMeasles was more often seen in the children under the age of 9 months from the floating population. The morbidity peak month was from April to May in Shanghai. The H1a genotype was the only one genotype. We should try to improve vaccination coverage rate in the children who are at the age for vaccination, so as to prevent measles outbreak.

OBJECTIVETo investigate Salmeterol/Fluticasone Propionate and Totropiumi treatment of Sillicosis merger Asthma.

METHODS30 patients with Sillicosis merger Asthma were randomly divided into group Salmeterol/Fluticasone Propionate( Single group) ( n=14) and group Salmeterol/Fluticasone Propionate and Totropiumi (Joint group) ( n= 16), patient in single group were only given Salmeterol/Fluticasone Propionate (50 f.Lg Bid) inhaling,and those in Joint group were given Salmeterol/Fluticasone Propionate (50 f.Lg Bid) and Totropiumi ( 18 f.Lg Qd) inhaling. The treatment was last for 6 months.Before the treatment,evaluation of the two groups of Sillicosis installment,determination their foungation lung function and ACT score .. After the cause of treatment, lung function FEV10/FVC(% ), FEV10 pred%, FEV10(ml), ACT score, the incidence of side effects of two groups were compared and analyzed.

RESULTThe two groups before the treatment of lung fuction and ACT score had no statistically significant difference. The two groups after treatment of lung fuction FEV10/FVC (% ),FEV10 pred%, ACT score obviously higher than before treatment (P<0.05), Joint group in FEV1/FVC(% ), ACT score significantly higher than in Single group (?<0.05), Joint group acute attack times(0.98±0.79)/time lower than Single group (2.10 ± 0.81 )/time (t=3.86,P<0.05). There were no significant side effect in two groups.

CONCLUSIONSalmeterol/Fluticasone Propionate or the combination of Salmeterol/Fluticasone Propionate and Totropiumi can improve lung function and clinical symptoms of patients with Sillicosis merger Asthma. It is also better that the combination of Salmeterol/Fluticasone Propionate and Totropiumi obviously improve clinical symptoms of patients and reduice acute attack times.

Objective To investigate a reasonable and effective internal fixation method for posterolateral fracture of the tibial plateau. Methods Specimens of the tibial plateau with posterolateral fracture made from 12 adult male cadavers were randomly and evenly divided into 3 groups, and fixed by anterior 6.5 mm lag screw, lateral 4.5 mm L-shape plate, posterior 3.5 mm T-shape plate, respectively. All the specimens were loaded in turn by stress of 250, 500, 750, 1 000 N, and the corresponding axial displacement and stress were measured. Results Under the same stress, the Y-axial displacement of the anterior lag screw group was the smallest, showing a significant difference with the lateral plate group and the posterior plate group, while there was no significant difference between the lateral plate group and the posterior plate group in the Y-axial displacement. The stresses on marked points in the anterior lag screw group were evenly distributed. Conclusions For fixation of isolated posterolateral fractures of the tibial plateau, the anterior 6.5 mm lag screw can effectively increase the axial stability and balance the stress distribution around the fracture block, indicating it is an effective method for mechanical fixation. The lateral plate has certain advantage in lateral stability control, while the posterior plate has certain value to reduction of the posterior tibia plateau fracture.

OBJECTIVETo compare the clinical, pathological, laboratory test and follow-up data between familial and sporadic patients with distal myopathy with rimmed vacuoles (DMRV) and discuss the characteristics of this disorder in Chinese population.

METHODSThe clinical and pathological features, laboratory data and follow-up results of 33 sporadic and 4 familial cases of pathologically confirmed DMRV were summarized and compared retrospectively.

RESULTSThe patients age, onset age, or disease duration showed no significant difference between sporadic and familial cases; the onset pattern and affected muscle groups were also similar, but the sporadic cases showed more frequent dysmorphic features than the familial cases. The patients showed mild to moderate elevation of the muscle enzymes by one to three folds, and the familial patients had more significant elevation than the sporadic ones. No correlation was found between the disease duration and the level of muscle enzymes. The pathological findings were similar between the cases, and Gomori staining showed rimmed vacuoles and inclusion bodies without inflammatory cell infiltration. Follow-up results of 29 cases showed no significant difference between the two groups. The disease was slowly progressive and severely affected the quality of life of the patients, but did not produce obvious effect on the life expectancy.

CONCLUSIONThe clinical, pathological and laboratory data of Chinese DMRV patients are basically similar to those of Japanese cases. Sporadic cases tend to show more dysmorphic features than the familial ones, and occasional sporadic cases have early disease onset in early childhood.

Objective This study was undertaken to examine possible relationship between attempted suicide and underachievement,bullying,low life satisfaction and low self-concept at school.Methods An anonymous self-report survey assessing demographic characteristics and the major risk factors of teenage attempted suicide was completed by students from 16 middle schools in grades seven to twelve in 4 counties of Anhui province (age 10 to 21 years).An anonymous questionnaire was used to rate attempted suicide,bullying involvement and learning performance.Attempted suicide was defined as: experiencing specific suicide actions at least one time during the 12 months preceding the survey.Multidimensional Students' Life Satisfaction Scale and Children' s Self-concept Scale were used to evaluate satisfaction and self-conscience on and at respectively.In total,10 894 respondents substantially completed the survey.Multiple logistic-regression analyses,controlling for socio-demographic variables,was used to analyze if underachievement,bullying,low school life satisfaction and low children' s self-conscience at school had been risk factors.Results 629 participants (5.8%) reported having made at least one attempted suicide within the last 12 months.Students being underachieved were significantly having more attempted suicide events than those excellent students (X2=11.39,P=0.023).Students being both bully-victims and practiced bully were significantly more than those being only practiced bully (28.7% vs.15.8%,P＜0.001),being victims (28.7% vs.10.6%,P＜0.001) or having neither of them (28.7% vs.4.8%,P＜0.001).Results from multiple logistic regression analyses showed that underachievement,bullying,lower school life satisfaction and low self-conscience were risk factors for attempted suicide.Conclusion Data from this study confirmed that school bullying and children' s self-conscience at school were significantly associated with attempted suicide among rural middle school students in Anhui province.It is of importance to improve the school' s environments to reduce the risk of attempted suicide among this group.

Objective To elucidate the electrophysiological features of POEMS syndrome. Methods We retrospectively analyzed the electrophysiological findings of 22 patients of POEMS, and compared their results with those of 22 patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). Results Compared with the CIDP group, the motor nerve conduction velocity was decreased in the POEMS group, but the difference was not significantstatistically (P>0.05); whereas, distal motor latency (DML) was significantly decreased (P<0.05), and terminal latency index (TLI) was significantly increased (P<0.05). The incidence rate of the nerve conduction block in the POEMS group was lower than that in the CIDP group (P<0.05). Compound muscle action potential (CMAP) of the tibial nerve was decreased significantly in the POEMS group as compared with the CIDP group (P<0.05), whereas CMAP of the median nerve was not significantly different (P>0.05). Abnormal electrophysiology was frequently observed in muscles of lower limbs in the POEMS group, and in comparison of upper limbs, the difference was not significant statistically (P<0.05).Conclusion In POEMS syndrome, slowing of nerve conduction velocity is more predominant in the intermediate segments of the peripheral nerve, and conduction block is rare. Abnormal nerve conduction may be correlated with limbs.
