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.

Objective:To evaluate the short-term prognostic value of model for end-stage liver disease (MELD) combined with high density lipoprotein-cholesterol (HDL-C) in patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF).Methods:From December 2015 to December 2018, 182 patients with HBV-ACLF who were treated in Henan Provincial People′s Hospital were included. Prognosis and clinical data including HDL-C, total bilirubin, international standardized ratio (INR), creatinine of patients within 24 hours after admission were collected and analyzed retrospectively.The values of MELD were calculated. The binary logistic regression analysis was used to analyze the independent risk factors affecting 90-day mortality in HBV-ACLF patients.The receiver operator characteristic curve (ROC) and MedCalc 15.2 software were used to assess the predictive value of MELD, HDL-C and MELD-HDL-C model for prognosis. Kaplan-Meier survival curve was performed to analyze the prognosis of patients in different groups.Results:Sixty patients were divided into the death group and 122 patients were divided into the survival group according to the prognosis during hospitalization and 90 days after discharge. The MELD score of patients in the survival group was 21(19, 24), which was significantly lower than that in the death group (29(25, 34)), and the HDL-C value of patients in the survival group was significantly higher than that in the death group (0.3 (0.1, 0.6) mmol/L vs 0.2(0.1, 0.5) mmol/L). The differences were both statistically significant ( Z=-6.290 and -4.087, respectively, both P<0.01). Multivariate logistic regression analysis showed that MELD score and HDL-C value were the independent risk factors for 90-day mortality in patients with HBV-ACLF(odds ratio ( OR)=1.432, 95% confidence interval ( CI)1.271-1.613; OR=0.584, 95% CI 0.487-0.700, respectively; both P<0.01). Areas under the ROC of MELD, HDL-C and MELD-HDL-C scoring models were 0.775, 0.782 and 0.878, respectively. MELD-HDL-C scoring model was superior to both MELD and HDL-C , and the differences were both statistically significant ( Z=3.944 and 3.104, respectively, both P<0.01). When the MELD-HDL-C Youden′s index was set at 0.72, the optimal threshold was 24.69. Patients with MELD-HDL-C score≥24.69 had lower survival rate than patients with MELD-HDL-C score<24.69, and the difference was statistically significant ( χ2=142.900, P<0.01). Conclusion:MELD, HDL-C and MELD-HDL-C scoring systems could predict the short-term prognosis in patients with HBV-ACLF, and the predictive value of MELD-HDL-C has the superiority.

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.

ObjectiveTo explore the ultrasound characteristics of coronary artery fistula to improve its prenatal diagnosis.MethodsImaging data for 12 fetuses with coronary artery fistula who underwent fetal echocardiography at our hospital from June 2005 to December 2013 were retrospectively analyzed to summarize the ultrasound characteristics of coronary artery fistula.ResultsOf the 12 fetuses, 7 were confirmed with coronary artery fistula by echocardiography after birth, and the remaining 5 were aborted due to other cardiac abnormalities (since an autopsy was not performed, the diagnosis of coronary artery fistula could not be confirmed). Of the 7 confirmed cases, 1 had left coronary artery-to-right atrium fistula, 3 had left coronary artery-to-right ventricle fistula, and 3 had right coronary artery-to-right ventricle fistula; 1 had left coronary artery-to-right ventricle fistula with muscular ventricular septal defect, and 6 had simple coronary fistula. Two-dimensional ultrasound examination revealed that coronary arteries were displayed in all cases, and the diameter ranged from 1.8 to 4.0 mm. Color Doppler ultrasound clearly showed the fistula size, course and the situation fistulas drained into heart chambers. Diastolic regurgitation signal could be detected in the ascending aorta and aortic arch.ConclusionCoronary artery fistula can be diagnosed by color Doppler ultrasound combined with spectral Doppler ultrasound when the fetal coronary artery expands.

Objective To discuss the diagnostic value of 3D-ultrasound for cord entanglement in monoam-niotic twins. Methods From November 2013 to March 2016,a total of 65 monoamniotic twinsunderwent routine obstetric ultrasonography to screen fetal abnormalities in our hospital. The cord was meticulously observedusing a systematic continuous sequence approach. Fetuses who showed cord entanglement by 2-D ultrasound or 3-D flow Doppler were all recruited. The gestational weeks,fetal malformation,ultrasonic image feature of cord entangle-ment,and clinicaloutcome were recorded and analyzed retrospectively. Results 4 monoamniotic twins showed cord entanglement. Three-dimensional color Doppler clearly delineated thefeatures of entanglement. At following-up of 8 fetuses,3 fetuses were found intrauterine fetal death and 3 fetuses with structural abnormalities except for 2 well infants.Conclusion Cord entanglement may threaten the safety of fetusesin monoamniotic pregnancies.In aid of 2-D ultrasound or 3-D flow Doppler in monoamniotic twins can help to find it in time ,monitor it carefully and provide evidence for obstetric treatment .
