Objective To investigate the distribution of pathogens in adult patients with community-acquired pneumonia (CAP) in Tangshan area. Methods The clinical data of 530 hospitalized patients with CAP were retrospectively collected in department of respiratory medicine from 6 hospitals in Tangshan area from October 2011 to September 2012. The sputum samples were isolated and cultured. Results A total of 195 strains were isolated from 530 patients with CAP. The most common types of pathogens included Klebsiella pneumoniae (64 strains,12.08%), Streptococcus pneumoniae (24 strains, 4.53%) and Bauman Acinetobacter (19 strain, 3.58%). The detective rates of Klebsiella pneumoniae and Pseudomonas aeruginosa were significantly higher in patients with basic diseases than those of patients without basic diseases (P<0.05). The detective rates of Klebsiella pneumoniae and Streptococcus pneumoniae were significantly higher in patients not taking antibiotics than those of patients taking antibiotics (P<0.05). The detective rates of Klebsiella pneumoniae, Bauman Acinetobacter and Pseudomonas aeruginosa were significantly higher in the age group≥60 years than those in the age group<60 years (P<0.05). The detective rates of Klebsiella pneumoniae were significantly increased with increased levels of PORT (P<0.05). There were no significant differences in the detective rates of pathogens between different regions and different seasons (P>0.05). Conclusion The gram-negative bacterial pathogens were the majority isolated from patients with CAP in Tangshan area. And Klebsiella pneumoniae was the primary bacteria. Patients with serious illness, above 60 years old, without antibiotic treatment before hospitalization, with basic diseases and above PORTⅢlevels should be given treatment of anti-gram-negative bacteria.

Objective To evaluate the efficacy of biliary tract prosthesis and pancreatic duct stents for advanced periampullary carcinoma. Methods A total of 36 patients were diagnosed as advanced periampullary carcinoma pathologically or clinically, with strictures both in pancreatic and biliary ducts confirmed by imaging. Teflon stents were firstly implanted through endoscopy to the narrowed pancreatic ducts, expansible metal prosthesis were then implanted to the biliary tract. If failed, the metal stents were given through percutaneous transhepatic biliary drainage (PTCD) pathway. Serum levels of liver enzymes, amylase and clinical manifestations were observed before and after operation. Results Teflon stents were successfully implanted into pancreatic ducts in all patients. Metal prostheses into bile ducts were endoscopically implanted in 29 cases, and via PTCD in 7, including 2 cases of Billroth Ⅱ gastrectomy. The levels of liver enzymes significantly decreased (P<0.01) after stents implacement. The levels of amylase (plasma and urine) and lipase increased in 15 cases, but they were corrected to normal levels after adequate treatments. Rates of abdominal pain relieving and diahhrea improvement were 82.4% (28/34) and 88.2% (15/17), respectively. Conclusion The combined implacement of biliary tract prosthesis and pancreatic duct stents is safe and effective in relieving malignant obstruction in periampullary carcinoma.

Background and purpose:Endoscopic treatment is a promising therapeutic option for superifcial lesions throughout the gastrointestinal tract, this study was aimed to evaluate the efficacy of endoscopic resection (ER) using the new Duette multiband mucosectomy kit (DT-6) on treating esophageal disease. Methods:Since Jun. 2011, ER using DT-6 has been performed on 100 patients in a tertiary medical center. Data from those who have been followed up for over 6 months was analyzed. ER and esophagectomy were compared on treating high grade dysplasia (HGD) lesions and early esophageal cancer. Results:From Jun. 2011 to Jan. 2012, a total of 32 patients with esophageal lesions underwent 34 ER using DT-6 (22 male and 10 female, mean age 59.0 years, range 25 to 83 years). There were (3.4±1.0) specimen resected per operation, and the average greatest diameter was (11.8±2.7)mm. Intraoperative blood loss was (5.45±1.47)mL. The median follow-up period was 8.2 months with a 100%half-year-follow-up rate. Except one pneumothorax occurred during one endoscopic submucosal dissection (ESD), no other complications happened. When Comparing ER and esophagectomy on treating HGD and early esophageal cancer, ER showed advantages in terms of operation time, intraoperative blood loss, hospital stay and complications. Conclusion:ER using DT-6 is safe, simple, minimally invasive and effective for esophageal disease. Prospective study and long follow-up are needed to compare endoscopic resection and esophagectomy for HGD and early esophagus cancer.

Objective To evaluate the short-term and long-term effects of pharyngeal airway in mandibular prognathism patients after the combined orthodontic and orthognathic treatment.Methods The sample included 28 skeletal Class Ⅲ patients (13 males,15 females) who had undergone mandibular setback surgery and orthodontic treatment.Cone-beam CT was taken one week before treatment (T0),6 months (T1) and 3 years after surgery (T2).Raw data were reconstructed into three-dimensional model.Sagittal and transversal measurements,cross sectional areas,partial and total volumes were computed.Results Six months after surgery,oropharyngeal volume [(9 021±4 263) mm3],hypopharyngeal volume [(9 236±5 963) mm3] and total volume [(28 619±9 854) mm3] decreased significantly (P＜0.05).Three years after surgery,only sagittal diameters [(15.9±3.5) mm] and cross sectional areas [(996±398) mm2] in the first cervical vertebra plane came back to the original levels (P＞0.05).Conclusions The pharyngeal airway space decreased after orthodontic-orthognathic therapy in the short term and it increased in some areas in the long term.

Objective: To explore the gender-specific risk factors of new-onset cerebral hemorrhage. Methods: In this prospective cohort study,a total of 98 961 participants((51.1±12.6)years old), who underwent the 2006 to 2007 physical examination and met the inclusion criteria, were enrolled from the Kailuanstudy cohort. There were 78 908 (79.7%) male,and 20 053 (20.3%) female.The incidence of cerebral hemorrhage was observed once per year until December 31, 2016.The difference on the incidence of cerebral hemorrhage between male and female was compared. Multivariate Cox regression analysis was applied to analyze therisk factors of cerebral hemorrhage events among different genders. Results: The participants were followed up for(10.00±0.73) years,and 860 cerebral hemorrhage events were recorded during follow up. The incidence of cerebral hemorrhage in the population was 86.90/10 million person years (standardized incidence rate of 47.85/10 million person years). The incidence of cerebral hemorrhage was significantly higher in male (49.61/10 million person years) than in female (34.07/10 million person years, P<0.05). Multivariate Cox regression analysis showed that 45-59 years old, ≥ 60 years old, diabetes,and waist-hip ratio were more strongly related to new-onset of cerebral hemorrhage events in female than in male, and the hazard ratios(95%CI) were 2.33 (1.23-4.43) ,2.71 (1.30-5.66) ,2.16 (1.24-3.74) and 8.79 (1.42-54.32) in female versus 1.55 (1.21-1.97) ,2.16 (1.68-2.78) ,1.19 (0.93-1.53) and 3.21 (1.09-9.41) in male, respectively. The risk of male cerebral hemorrhage increased by 29% (HR=1.29, 95%CI 1.19-1.40) in male and 24% (HR=1.24, 95%CI 1.20-1.28) in female,when the systolic blood pressure increased 10 mmHg (1 mmHg=0.133 kPa). Conclusions: The incidence of cerebral hemorrhage is higher in male than in female in this cohort.The association between systolic blood pressure and cerebral hemorrhage is stronger in male than that in female.The associations between age, waist-hip ratio, diabetes and cerebral hemorrhage are stronger in female than in male.

Pancreatic cancer is among the most malignant cancers,and thus early intervention is the key to better survival outcomes.However,no methods have been derived that can reliably identify early precursors of development into malignancy.Therefore,it is urgent to discover early molecular changes during pancreatic tumorigenesis.As aberrant glycosylation is closely associated with cancer progression,numerous efforts have been made to mine glycosylation changes as biomarkers for diagnosis;however,detailed glycoproteomic information,especially site-specific N-glycosylation changes in pancreatic cancer with and without drug treatment,needs to be further explored.Herein,we used comprehensive solid-phase chemoenzymatic glycoproteomics to analyze glycans,glycosites,and intact glycopeptides in pancreatic cancer cells and patient sera.The profiling of N-glycans in cancer cells revealed an increase in the secreted glycoproteins from the primary tumor of MIA PaCa-2 cells,whereas human sera,which contain many secreted glycoproteins,had significant changes of glycans at their specific glycosites.These results indicated the potential role for tumor-specific glycosylation as disease biomarkers.We also found that AMG-510,a small molecule inhibitor against Kirsten rat sarcoma viral oncogene homolog(KRAS)G12C mutation,profoundly reduced the glycosylation level in MIA PaCa-2 cells,suggesting that KRAS plays a role in the cellular glycosylation process,and thus glycosylation inhibition contributes to the anti-tumor effect of AMG-510.
