Hepatitis C and its complications are one of the highlights in liver disease prevention and control in China,and from the clinical practice 20 years ago to a cure rate of nearly 100％ at present,standardized diagnosis and treatment of hepatitis C,a large number of scientific studies,and drug research and development are the basis for the clearance of HCV.Direct-acting antiviral agents play an important role in the clearance of HCV,and the clearance of HCV does not equal to the cure of chronic hepatitis C.For patients with hepatitis C who have achieved a high sustained virologic response rate after using direct-acting antiviral agents,their long-term prognosis should be taken seriously.Correct and reasonable application of hepatitis C treatment is still a hot issue that needs to be discussed at present.

Objective To investigate the relationship between obesity parameters and obstructive sleep apnea-hypopnea syndrome (OSAHS) in aircrew. Methods A questionnaire survey in aircrew members was performed. Outcome measurement included body height, body weight, neck circumference ( NC), waist circumference (WC), and body mass index (BMI). Those with snoring during sleep and/or Epworth sleepiness scale (ESS)score ≥ 9 were screened with pulse oxygen saturation test during overnight sleep. Those with oxygen saturation decrease index ≥ 10 times/h and suspected OSAHS were tested by polysomnography (PSG). The objects were then assigned to three groups: the OSAHS group,the snore group and the normal group. The relationship between obesity parameters and OSAHS was analyzed. Results There were 399 ( 37. 54% ) overweight, 36 ( 3. 39% ) obesity, 130 ( 12. 23% ) increased NC, and 354 (33.30%)increased WC in 1063 aircrew members (OSAHS group ＞ snore group ＞ normal group; P＜O. 05). The mean value of BMI, NC and WC in the three groups were dittos. Multiple logistic regression analysis showed that overweight, obesity and increased WC were significantly associated with snoring (P ＜0.05) and snoring enlarged NC was significantly correlated with OSAHS (P＜ 0.05). Conclusion Increased BMI, NC and WC may be risk factors of OSAHS among aircrew. Effective prevention and treatment of OSAHS should be needed.

Objective To explore the clinical characteristics,pathogens,inflammatory biomarkers,therapeutic methods and prognosis of necrotizing pneumonia (NP) in children.Methods The clinical data of children with NP who were admitted to the Department of Pediatrics of Shengjing Hospital of China Medical University from October 2010 to October 2015 were collected.The data included demographic data,laboratory test results,intrapulmonary complications,therapeutic methods and so on were analyzed,retrospectively.Results Forty-nine pediatric patients with NP were enrolled,31 cases were boys,18 cases were girls;the average age of the patients were 2.5 years (4 months-13 years).The average febrile time were (15.08 ± 5.92) d,and the hospital stay was (21.19 ± 10.83) d,respectively.The median value of peripheral blood leukocyte count was 17.7 × 109/L,the average of neutrophils ratio was (67.62 ± 18.52)％,and the median value of C-reactive protein (CRP) and procalcitonin (PCT) was 97.9 mg/L and 0.54 μg/L,respectively.Nineteen cases had Mycoplasma pneumoniae (MP) infection,16 cases with pneumonia chlamydia infection,9 cases complicated with MP and chlamydia pneumoniae infection,and 8 cases with positive bacterial culture,and 10 cases suffered from the intrapulmonary complications.Forty-seven cases got better prognosis with the treatment of antibiotics,glucocorticoids,intravenous immunoglobulin and other comprehensive therapeutic methods such as bronchoalveolar lavage with fiber bronchoscope and closed thoracic drainage.Conclusions NP is a severe complication of community-acquired pneumonia in children,and the occurrence of NP should be alerted in the children who have persistent high fever,higher inflammatory index and pleural effusion,but the great majority of patients do recover fully after comprehensive treatment.

ObjectiveTo analyze and summarize the feasibility and characteristics of the posterior spinal canal reduction and fixation in treating mid-upper thoracic spine facture.MethodsA retrospective study was made on 17 patients with mid-upper thoracic spine facture to record the complication, compare the functions of the patients with complete and incomplete spinal cord injuries before and after surgery and examine the iatrogenic injury in patients without spinal cord injuries.ResultsNo complication happened after surgery.Incomplete injury was found in six patients, whose ASIA scales were found to be increased for 1-3 levels during the follow-up.While the complete injury was found in eight patients,whose ASIA scale remained unchanged during the follow-up.The sensory scores of both the incomplete injury group and complete injury group were processed with variance analysis and the results showed a significant difference between pre-operation and post-operation (F = 476.47, P = 0.000).The mean value between complete injury group and incomplete group was with high statistical difference (F = 31.46, P =0.000).The variance analysis of the motor scores showed a significant difference between before and after operation (F=46.75, P =0.000) and the mean value between complete and incomplete injury groups was with statistical difference (F = 158.59, P = 0.000).There were three patients with normal spinal cord function, with no decrease of ASIA scale or no change of the sensory and motor scores.ConclusionsFor patients with mid-upper thoracic spine fracture, posterior spinal surgery is conducive to the recovery of spinal function, for it can safely and effectively avoid worsening the thoracic and other combined injuries and release spinal pressure including the pressure in front part of the spinal cannal.

Objective To investigate the role of serum and glucocorticoid regulated protein kinase (SGK) 1 in the inflammatory responses mediated by toll like receptors.Methods Mice were injected with lipopolysaccharide (LPS,1 mg/kg) 2 h after the pretreatment of EMD638683 (10 mg/kg) or phosphate buffered saline (PBS) as control.At the time points of 3 and 24 h,pro-inflammatory cytokines (interleukin [IL]-6,IL-12 and tumor necrosis factor [TNF]-α) in serum were measured using enzymelinked immunosorbent assay (ELISA).Livers and lung were harvested at 6 h and 24 h after the injection of LPS,embedded by optimum cutting temperature (OCT) and then stained with hematoxylin and eosin (HE).Peripheral blood mononuelear cell (PBMC) were isolated and stimulated by LPS with or without the pretreatment of EMD or LY294002.Cytokines (IL-6,IL-12 and TNF-α) were measured using ELISA.IKKα/β,IKBα and nuclear factor (NF)-κB p65 were detected by Western bolt.Data were analyzed by one way analysis of variance.Results In the model of LPS-induced endotoxin sepsis,inhibition of SGK1 induced secretion of pro-inflammatory cytokine (IL-6 [t=3.007,P＜0.05],IL-12[t=4.413,P＜0.05] and TNF-α[t=5.403,P＜0.05]),increased inflammatory cells infikration into the liver and lung within 6 h,and induced serious multiple organ damage with collapse of alveoli and fatty degeneration of liver.After 24 h,pharmacological inhibition of SGK1 with EMD638683 increased proinflammatory cytokine (IL-6 [t=18.540,P＜0.01],IL-12[t=16.520,P＜0.01] and TNF-α[t=34.880,P＜0.01]) production in human PBMC upon LPS stimulation and inhibited the phosphorylation of IKKα/ β/IKBα and nuclear factor (NF)-κB p65.Conclusions SGK1 suppresses the toll like receptor 4 mediated inflammatory responses via NF-κB.
