" Two-way referral, and synergy between the tertiary hospitals and primary institutions" is the core measure for promoting hierarchical diagnosis and treatment in the region. The authors introduced the exploration and practice of constructing a two-way referral path in the medical alliance based on telemedicine in West China Second University Hospital of Sichuan University. As of May 2021, the hospital had established a two-way referral path with 52 member hospitals of the medical alliance. By clarifying the functionality and positioning of these institutions, optimizing work processes and IT support, building the mechanism of referral and liaison, and that of appraisal as support, these efforts had achieved progresses in such fields as innovative medical service modes, lean management of referral processes, and promotion of hierarchical diagnosis and treatment system building.

As one of the main forms of the medical alliance, the specialty alliance functions as a service carrier for hierarchical medical service and resources integration in the region. The authors introduced the exploration and practice of the West China Women′s and Children′s Alliance, the first pediatric specialty alliance in Sichuan, established by the West China Second Hospital of Sichuan University. Based on family doctor contracted services, the West China Women′s and Children′s Alliance took such measures as differentiated functional positioning, assessment of certified physicians, continuous online quality control, construction of referral platforms, and innovative payment mechanisms. Such efforts effectively integrated the three stages of pre-hospital " preventive care" , in-hospital " disease diagnosis and treatment" , and post-hospital " follow-up management" , exploring the homogenization of medical services within the alliance, and forming a pediatric closed-loop health management system, hence improving the primary medical services.

OBJECTIVETo investigate the effect of curcumin against cigarette smoke extract (CSE)- induced oxidative stress in human bronchial epithelial cells and explore the underlying mechanism.

METHODSHuman bronchial epithelial cell line 16HBE was treated for 24 h with curcumin, CSE, CSE + curcumin, and CSE + curcumin with transfection by a short hairpin RNA targeting PPARγ (shPPARγ). MTT assay was used to observe the changes in the cell viability after the treatments. Quantitative real-time PCR was performed to detect the mRNA expressions of tumor necrosis factor- (TNF-), iNOS and PPARγ in the cells, and the protein expressions of iNOS, PPARγ and the phosphorylation of NF-κB p65 were detected using Western blotting.

RESULTSThe treatments did not cause significant changes in the cell viability. Exposure to CSE for 24 h significantly lowered PPARγ expression and increased TNF- and iNOS expressions and phosphorylation of NF-κB p65 in the cells. The effects of CSE were significantly suppressed by curcumin, but transfection of the cells with shRNA-PPARγ obviously abrogated the suppressive effects of curcumin.

CONCLUSIONSCurcumin suppresses CSE-induced oxidative stress and inflammation via the PPARγ/NF-κB signaling pathway in 16HBE cells, suggesting the potential of curcumin in the treatment of chronic obstructive pulmonary disease.

OBJECTIVE: To explore the relevance between nasal symptoms and laryngopharyngeal reflux disease in patients with allergic rhinitis. METHOD: Thirty patients of laryngopharyngeal reflux disease were diagnosed in ENT outpatient department in our hospital. All patients have symptoms of sneeze, nasal discharge as chief complaint and they responded no effect for other normal treatment for nasal-sinusitis at least three months. Orally before meals, a dose of 5 mg Mosapride citrate each time, three times a day for 7 days. Orally before meals, a dose of 20 mg Esomeprazole each time, two times a. day for 2-3 months. Nasal spray, one spray of azelastine hydrochloride once, two times a day for 2 month. RESULT: Laryngopharyngeal reflux symptom scores at four time points (the first visit, post treatment 15 days, 45 days, 75 days) were analyzed by repeated measures analysis of variance. There is a significant difference in four time points. CONCLUSION Laryngopharyngeal reflux disease has a strong association with allergic rhinitis. Patients who has allergic rhinitis nasal symptoms as chief complaint must be exclude, the laryngopharyngeal reflux disease first.

OBJECTIVE: To study the distribution and drug sensitivity test of bacteria of patients on chronic rhinosinusitis with or without nasal polyps. METHOD: The purulent discharges were collected from sinus of 175 patients with chronic rhinosinusitis with or without nasal polyps during endoscopic sinus surgery. The results of germiculture and drug sensitivity test were analyzed. RESULT: From 175 specimens, 118 (67%) showed positive results in germiculture. Among them, 79 strains of gram positive bacteria and 39 strains of gram negative bacteria were detected. Staphylococcus epidermidis, Staphylococcus aureus and Staphylococcus haemolyticus were the most common pathogens in gram positive bacteria. The most common pathogens of gram negative bacteria were P. Aeruginosa, Enterobacter aerogenes, Enterobacter cloacae. The sensitive antibiotic on gram positive bacteria were amikacin, Daptomycin, Linezolid, vancomycin, teicoplanin, amoxicillin and clavulanate potassium, cefuroxime, respectively. The sensitive antibiotics on Gram negative bacteria were amikacin, Cefoperazone/sulbactam and imipenem, ceftazidime ceftazidime, aztreonam, levofloxacin, respectively. CONCLUSION Bacterial infection was common happened in the sinus cavity of patients with chronic rhinosinusitis with or without nasal polyps. Gram positive bacteria were the main pathogenic bacteria and gram positive bacteria and gram negative bacteria have great differences in the sensitivity of antibiotics. For patients with chronic rhinosinusitis, the using of antibiotics should depend on the drug sensitivity test.
