Objective To investigate the diagnostic significance of endoscopic findings in Henoch-Schonlein purpura(HSP),especially when abdominal pain preceded the cutaneous lesions.Methods The clinical data and gastroscopic findings in 37 cases of children with HSP were studied and analysed retrospectively in order to detect the pathological changes in the stomach and duodenum mucosa.The biopsy was taken in the pathological changeing place,and the relationship between clinical and endoscopic findings was analyzed.Results Detection rate of the pathological changes in the stomach and duodenum mucosa was 62.2%,31.3% of which experienced only cutaneous lesions,100% of which presented the acute abdominal pain.Three patients were not checked up the pathological changes.Of them,1 had arthritis,2 had Henoch-Schonlein nephritis.Characteristically endoscopic findings in the stomach and duodenum mucosa were found.The endoscopic findings included anabrosis,hyperemia,edema and hemorrhage.Conclusions Detection rate of the pathological changes in the stomach and duodenum mucosa is higher.Endoscopy is very helpful to the early diagnosis of HSP in children,especially abdominal pain presented firstly.

A total of 152 strains of endophytic fungi were isolated from the barks of Eucommia ulmoides in three regions (Lueyang country, Zunyi country, Cili country). Based on morphological characteristics and analysis of ITS sequences, these strains were identified into 8 genera. Thereinto Phomopsis, Diaporthe and Alternaria were common genera to Eucommia barks from different sites. But the dominant genus was different: Alternaria was the dominant genus in the barks from Cili country, and Phomopsis was the dominant genus from Zunyi country, then Diaporthe was the one from Lueyang country. According to the similarity coefficient, the composition of the endophytic fungi was distinctly different between the barks from three sites. The diversity and species richness in Lueyang country and Cili country were found higher than those in Zunyi country. The evenness of endophytic fungi was 0.936 5 in Lueyang county, which was higher than 0.737 1 or 0.641 0 in Cili county or Zunyi county, respectively. After phylogenic analysis and calculating the genetic distances of typical strains belong to Phomopsis and its perfect stage--Diaporthe, there was very high genetic diversity in the two genera from our study. In conclusion, the community structure and diversity of endophytic fungi were significant different in Eucommia barks from the three habitats.

The relationship between serum uric acid(SUA) and hypertension was investigated and the interactions of SUA with metabolic risk factors was assessed. Blood pressure and biomarkers features were evaluated for all the8 415 individuals from a community-based health examination survey in Xuzhou, and the statistical analysis was made. Raised blood pressure was associated with increased SUA concentration(P＜0.01). Age and high density lipoprotein cholesterol(HDL-C) significantly interacted with SUA(P for interaction=0.012 and 0.001, respectively). There is significant association between SUA and hypertension, which may be affected by age and HDL-C levels.

Objective To summarize the experience of the therapy and diagnosis of thoracictuberculosis. Methods Diagnosis and operation of 163 cases of thoracictuberculosis were analyzed.Results 163 cases of thoracic- tuberculosis were treated with focuspurge upon two weeks' anti-tuberculosis treatment.153 cases were cured upon one operation.10 cases suffered incision delayed healing and there were no recurrence cases.Conclusion Thoraeictu- berculosis was treated with focuspurge upon two weeks anti-tuberculosis treatment before operation.Complete purge of focus and postoperative compression band and residual cavity filled with music flap were important measures to prevent incision delayed healing and recurrence.

Objective To analyze the differential proteomics of ASMC stimulated by wild IL-13 and mutant IL-13 and to investigate the relations of protein profiles of ASMC to asthma and possible targets for the treatment of bronchial asthma.Methods The total proteins of ASMC stimulated by wild IL-13 and mutant IL-13 were separated by immobilized pH gradient(IPG)-based 2-DE and the differentially expressed protein spots were identified by matrix assisted laser desorption-time of flight mass spectrometry(MALDI-TOF-MS). Results The 2-DE detected approximately(840?21)spots on wild IL-13 samples and(892?17)spots on mutant IL-13 samples(n=3)and(685?19)spots matched.Six significantly differential proteins were subjected to MALDI-TOF-MS analysis and three of them were identified as stathmin 1,Ribosomal protein p~0 and NADH dehydrogenase.Conclusions ASMCs stimulated by wild IL-13 and mutant IL-13 present different proteomic profiles that may shed some light on the mechanism for the asthma causing effect of wild IL-13 and mutant IL-13.

Background and purpose:Coventional radiation has been used for decades,but the 3D dose distribution has not been studied as yet.In this study,different treatment plans of conventional irradiation technique for esophageal carcinoma have been evaluated by 3-D TPS.Methods:Five patients with esophageal carcinoma at upper-thoracic and five patients at middle-thoracic were enrolled in this study.Three conventional treatment plans were created for each patient,with a prescribed dose of 70 Gy.For tumor at upper-thoracic,plan 1 consisted of one anterior field and bilateral posterior oblique fields with wedges,plan 2 consisted of anterior bilateral oblique fields with wedges ,plan 3 consisted of a pair of AP-PA portals,then followed by right anterior oblique portals and left posterior oblique portals to spare spine cord.For tumor at middle thoracic,plan 1 consisted of one anterior field and bilateral posterior oblique fields.Plan 2 consisted of a pair of AP-PA portals and followed by another pair of parallel-opposed lateral off- cord fields as boost.Plan 3 used the same plan as for the lesion at upper-thoracic.The evaluation of each treatment plan was carried out by dose-volume histogram(DVH).Results:For tumor at upper-thoracic,on average,the maximum dose to spinal-cord in plan 3 was (57.1?4.9)Gy,and was higher than that in plan 1 and plan 2.Plan 1 increased mean lung dose from (12.8?2.1)Gy to (18.2?4.1)Gy(P=0.045)compared with plan 2,but it improved the homogenous dose of PTV2,especially in the patient with long tumor.For tumor at middle-thoracic,on average,plan 2 increased mean lung dose from (11.9?1.1)Gy to (13.0?0.6)Gy(P=0.045) compared with plan 3.Plan 2 increased V_(20) and V_(30) from (23.6?2.3)% to (29.2?1.9)%(P=0.004) and (13.9?2.3)% to (20.9?1.3)%(P=0.006) compared with plan 1.The trachea volume of(?)70 Gy(V_(70))in plan 3 was larger than that in plan 1[(20.3?15.9)% VS (10.5?9.8)%,P=0.058].Conclusion:For tumor at upper-thoracic,plan 1 and 2 were superior to plan 3.Irradiation to lung in plan 2 was lower than that in plan 1,but plan 1 improved the homogenous dose of PTV2 compared with plan 2,especially for patient with longer lesion.For tumor at upper-thoracic,plan 2 increased irradiation dose to lung compared with plan 1 and plan 3.Plan 1 was comparable with plan 3,but the dose of trachea in plan 1 may lower than that in plan 3.

OBJECTIVETo evaluate the overall effect of transsphenoidal microsurgery for pituitary adenomas in recent 5 years and to discuss the surgical technique, application of new technology and postoperative follow-up results.

METHODSThe clinical presentation, image characteristics, endocrinal findings, pathological types, tumor removal percentage, postoperative complication and follow-up of 1 462 patients with pituitary adenomas who underwent the transsphenoidal microsurgery from 1997 to 2002 were analysed retrospectively.

RESULTSTotal rate of tumor removal for the patients achieved 97.0% in the patients with Hardy I adenomas, 95.2% with Hardy II, 90.5% with Hardy III, and 47.4% with Hardy IV respectively. A significant postoperative improvement both in clinical symptoms and endocrinal parameters was achieved. The tumor recurrence rate was 0.3%.

CONCLUSIONSWith the improvement of microsurgical technique and application of novel technology, the indication of transsphenoidal microsurgery for pituitary adenomas was increasingly extended. Endoscope and(/or) neuronavigation-assisted microsurgery via transsphenoidal approach should be of the first choice for the treatment of pituitary adenomas. The routine postoperative radiotherapy is not required for patients with total tumor removal.

Objective To explore the clinical significance of prenatal diagnosis for absence of fetal cavum septum pellucidum (CSP) by ultrasonography. Methods The ultrasonographic characteristics were retrospectively analyzed in 63 fetuses, whose CSPs were not detected in prenatal two and three dimensional ultrasonography in Nanjing Medical University Affiliated Suzhou Hospital. Results In 63 fetuses with absent CSP, the related malformations included:(1) Five cases were diagnosed as agenesis of corpus callosum (ACC, including four complete ACC and one partial ACC);(2) Twenty-seven cases were diagnosed as holoprosencephaly (HPE, including 18 alobar HPE, ifve semilobar HPE and four lobar HPE);(3) One case was diagnosed as schizencephaly;(4) Two cases were diagnosed as porencephaly;(5) Five cases were diagnosed as hydranencephaly;(6) Twenty-three cases were diagnosed as severe hydrocephalus, among which ifve cases were caused by aqueductal stenosis and the other 18 cases were caused by open spina biifda (Chiari Ⅱ malformation). These absent CSP fetuses had other abnormalities including one case of Dandy-Walker Malformation, one case of Dandy-Walker Variation, 14 cases of median cleft lip, ifve cases of single naris, two cases of proboscis nose, three cases of talipes foot and four cases of single umbilical artery, etc. These 63 cases were all followed up after prenatal ultrasonography but 4 cases were missed and one case of septo-optic dysplasia was misdiagnosed as lobar HPE. The diagnoses of other 58 fetuses by ultrasonography were conifrmed by follow up. Conclusions CSP is considered as an essential part in prenatal evaluations of the fetal central nervous system during second-and third-trimester. Absence of CSP is always accompanied with an extremely wide spectrum of fetal neuroanatomic malformations, including prosencephalon diseases, intracranial midline anomalies, etc. Prenatal ultrasonography is the best choice for the observation of CSP.
