Objective To investigate the pathological features of gastro-esophageal high-grade intraepithelial neoplasia (HGIEN) confirmed by biopsy and to compare the differences of its diagnosis after endoscopic resection. Methods Data of 147 patients with gastro-esophageal HGIEN confirmed by biopsy, who underwent EMR or ESD in recent 4 years were analyzed for the pathological findings of pre- and post- procedures. Results Among 147 cases of HGIEN diagnosed by endoscopic biopsy, 106 lesions were in esophagus and 41 in stomach. After endoscopic resection, intraepithelial neoplasia was confirmed in 97 (66%), and cancer was diagnosed in 50 (34%), of which submucosal layer was involved in 11. There were 34 cases of adenocarcinoma and 16 squamous cell carcinomas, in which 22 cases (44%) were poorly or moderately differentiated. Conclusion More than one third cases of biopsy diagnosed HGIEN are confirmed to be carcinoma after endoscopic resection, which needs active therapeutic measures.

Objective To evaluate endoscopic ultrasonography (EUS) in assessing endoscopic re-sectability of early esophagogastric cancer. Methods Data of 65 consecutive cases suspected as having early esophagogastric cancer with EUS and confirmed by pathology after endoscopic mucosal resection or endoscop-ic submucosal dissection within 2 weeks were retrospectively analyzed. The invasion depth of the lesion de-tected by EUS was compared with that from pathology. Results The accuracy of EUS in diagnosis of depth of early cancer invasion was 93.8% (61/65), and the overall accuracy in assessment of endoscopic resectabili-ty was 89. 2%. Conclusion Endoscopic resectability of early esophagogastric cancer can be accurately eval-uated with EUS.

Objective To investigate the early diagnosis and treatment of primary gastrointestinal malignant lymphoma( PGIML). Methods The clinical materials of 33 cases with PGIML from 1997 to 2005 were retrospectively studied. Results The diagnosis rate of gastroenteroscopy was 44. 4% . The most common immune phenotype was B-cell lineage (90. 9% ). Of the 33 PGIML patients, 30 were treated with operation, 2 with H. poli elimination and 1 gave up treatment. Among the operation cases and operation plus chemotherapy cases 19/21 cases (90. 5% )and 6/9 cases (66. 7% ) survived more than 2 years respectively, the other 6 cases died. Conclusion It is hard to diagnose PGIML in early stage. The effectiveness of surgery on treating PGIML should be further confirmed by profound prospective randomized trials.

Objective To understand the development history and current situation of healthcare-associated infection(HAI)management in children’s hospitals in China during the past 30 years.Methods A retrospective survey was conducted in 20 children’s hospitals,the investigated contents included:basic situation of hospitals, HAI management organizations and professionals,the support of hospital leaders for the management of HAI, training on HAI knowledge,monitoring on HAI,and so on.Results Up to 2015,20 hospitals all set up independent HAI management departments and HAI management committees,46.15%(6/13)of hospitals with more than 1 000 beds were understaffed in HAI management.There were a total of 88 professionals in HAI management in 20 children’s hospitals in 2015,53.41% (n=47)of professionals had bachelor degree,34.09% (n=30)were with intermediate professional title,46.59%(n=41)were nursing staff.Up to 2015,incidences and missing report rates of HAI,antimicrobial usage rates,incidences of HAI in neonates all decreased compared with 2006.In 2015,20 (100.00%)hospitals all carried out monitoring on antimicrobial application,multidrug-resistant organisms,disin-fection and sterilization,and provided personnel protective equipment.In 2015,9(45.00%)hospitals used non-tou-ch faucets in all wards,19(95.00%)hospitals supplied hand-drying paper towel and alcohol-based hand rub in all wards.None of professionals in these hospitals participated in national-level training on HAI for ≥3 times in 1996, professionals in 11 hospitals (55.00%)participated in national-level training for ≥3 times in 2015.Conclusion In the past 30 years,the management of HAI in children’s hospitals in China has basically met the requirement,moni-toring on HAI gradually improved,but allocation of HAI professionals and personnel quality ability still need to be strengthened.

Methylmalonic aciduria (MMA) is a common inherited autosomal recessive disorder resulting from defects in the enzyme methylmalonyl CoA mutase (MCM, mut complementation group) or in the synthesis of the MCM cofactor adenosylcobalamin (cbl complementation groups). The defects in the mut complementation group accounts for the largest number of patients with isolated MMA. At least 200 mutations in the MUT gene on chromosome 6p12 have been identified in MMA patients until now. This study aimed to investigate the clinical characteristics of MMA and genomic variations in the MUT gene of Chinese patients. Genomic DNA was extracted from 18 patients who were diagnosed as having isolated MMA by gas chromatography/mass spectrometry (GC-MS), and from some of their parents as well. Amplification and direct sequencing of the MUT coding regions (exon 2-13) and their adjacent intronic consensus splice sites were performed in order to identify the disease causing mutations. In this group, six novel mutations in the MUT gene, c.424A>G (p.T142A), c.786T>G (p.S262R), c.808G>C (p.G270R), c.1323_1324insA, c.1445-1G>A and c.1676+77A>C were identified. p.T142A and p.G270R were respectively detected at a heterozygous level in one patient. Two previously reported mutations, c.682C>T (p.R228X) and c.323G>A (p.R108H) were also found in this study. In addition, six previously described single nucleotide polymorphism (SNP), c.636A>G (p.K212K), c.1495G>A (p.A499T), c.1595A>G (p.H532R), c.1992G>A (p.A664A), c.2011G>A (p.V671I) and c.1677-53A>G were identified. In this study, we updated the spectrum of MUT mutations and identified the main MMA-causing mutations in Chinese MMA patients.

This study retrospectively reviewed 9 cases of complicated hepatic cystic hydatidosis with intrabiliary rupture who were surgically treated with pericystectomy in combination with Roux-en-Y hepaticojejunostomy in our hospital from 2004 to 2010. The clinical features, results of laboratory tests, B-mode ultrasonography and CT, post-operative recovery, days of hospital stay after the operation and post-operative complications were statistically analyzed and the patients were followed up. The subjects in our series included 7 males and 2 females, whose average age was 50.78±7.58 years. Before operation, 9 patients suffered from pain of the right upper quadrant and jaundice, which, in 4 cases (44.45%), were accompanied with fever and chills. Preoperative B-mode ultrosonography and CT showed that all the 9 patients had single hydatid cyst, with their diameter being 9.33±1.58 cm on average. The lesions involved segments V, VI in 6 cases, and segment IV in 3 cases. By WHO classification, 7 cases were classified as CE3 and 2 cases as CE4. They all had choledochectasia. The subjects underwent the surgery uneventfully. Intraoperatively, 2-4 biliary fistula orifices were found, with the average of the orifice being (0.79±0.20) cm. After the operation, one patient developed incision infection, one had pulmonary infection and one suffered from reflux cholangitis. No anastomotic leaks or peri-operative deaths took place and follow-up revealed no recurrence and implantative metastasis. We are led to conclude that pericystectomy in combination with Roux-en-Y hepaticojejunostomy can achieve satisfactory results for the treatment of complicated hepatic cystic hydatidosis with intrabiliary rupture.
