Background:The diagnostic accuracy of APRI and FIB-4 for liver fibrosis in patients with chronic hepatitis B is nothigh,especially for significant liver fibrosis (F≥2). Noninvasive diagnosis for liver fibrosis has become a research hotspot;and the diagnostic value of APRI combined with FIB-4 is not clear. Aims:To investigate the diagnostic value ofAPRI combined with FIB-4 for significant liver fibrosis in patients with chronic hepatitis B. Methods:A total of 171patients with chronic hepatitis B from January 2011 to October 2016 at General Hospital of Xinjiang Military Region wereenrolled. Liver biochemical indices,routine blood test and liver biopsy pathology were performed. APRI and FIB-4 werecalculated,ROC curve was drawn,and cutoff value of APRI and FIB-4 for diagnosing significant liver fibrosis wasdetermined,and mode of APRI combined with FIB-4 for diagnosing significant liver fibrosis was established. Results:Withthe increase in degree of liver fibrosis,APRI and FIB-4 were gradually increased (P < 0. 05). Area under ROC curve(AUC)for APRI and FIB-4 were 0. 812 and 0. 770,respectively. The sensitivity of FIB-4 for diagnosing significant liverfibrosis was higher than that of APRI. Sensitivity,specificity,negative predictive value,positive predictive value,andaccuracy of APRI combined with FIB-4 for diagnosing significant liver fibrosis were superior to APRI or FIB-4 used alone;and the specificity,accuracy of mode 2 were superior to mode 1. Conclusions:APRI combined with FIB-4 can increasethe accuracy for diagnosing significant liver fibrosis.

OBJECTIVE: To sum up the experiences of diagnosis, treatment and medical evaluation of head and neck tumors in aircrew. METHOD: Sixty-seven cases of pilot patients with head and neck tumors in our hospital since September in 1979 to July in 2009 were retrospective analyzed in the study. RESULT: Among 44 aircrew with benign head and neck tumors there were 37 cases continued their flying jobs and 7 cases were permanently grounded; whereas in 23 aircrew with malignant tumors there were 6 cases qualified for flight and 17 patients unqualified. CONCLUSION Benign or malignant of the head and neck neoplasm in the pilots are not the exclusive basis for their medical assessment. Tumor nature, location, efficacy of treatment and the impact on the function of their body should be considered as making the flight medical evaluation for the aircrew with head and neck tumors. Early diagnosis and treatment of head and neck tumors in aircrew are very important for reducing the rate of grounded.

OBJECTIVE: To sum up the experiences of diagnosis, treatment and medical evaluation of sinusitis and nasal polyp in aircrew. METHOD: Ninety three aircrew with sinusitis and nasal polyp were included in the study. RESULT: There were 11 cases with acute sinusitis and 82 cases with chronic sinusitis and nasal polyp. Of the 82 cases, there were 46 cases in class I (including 39 cases with symptoms and signs on ground in Ia, 7 cases only with signs in Ib), 36 cases in class II (no symptoms on ground but with symptoms of secondary barotraumas in flight, including 14 cases with secondary barosinusitis in IIa, 13 cases with secondary barotrauma in IIb, 9 cases with secondary barosinusitis and barotrauma in IIc ). Of the 82 cases, there were 24 cases in 1 stage of type I, 38 cases in 2 stage of type I, 7 cases in 3 stage of type I, 2 cases in 1 stage of type II, 6 cases in 2 stage of type II, 3 cases in 3 stage of type II, 2 cases in type III. Eighty four cases continued their flying jobs and 9 cases were permanently grounded. CONCLUSION Flying safe can be endangered by sinusitis and nasal polyp alone or with its secondary barotraumas. Chronic sinusitis and nasal polyp complicated with barotraumas are important causation for medical grounding. The aircrew with sinusitis and nasal polyp will be allowed to continue their flying jobs only after getting well curative effect and normal gas pressures of ear and nasal sinus.

OBJECTIVE: To analysis the characteristics of audiology and clinical genetics of a Chinese family with the DFNA5 genetic hearing loss in detail. METHOD: A detailed family history and clinical data were collected. The Chinese pedigree is an autosomal-dominant inherited hearing loss. The data of audiological examination about genetic characteristics was analysed. The relationship between the hearing-impaired of this family and age was contrasted. RESULT: This Chinese family spanned five generations and comprised 42 members. The mode of inheritance of the families should be autosomal dominant according to the pedigree. Pure-tone audiograms showed a so-called Z shape curve. The hearing loss is sensorineural, progressive and beginning at the high frequencies. The audiograms were fairly symmetric. Whole frequencies became involved with increasing age. CONCLUSION The Chinese family with the DFNA5 mutation was an autosomal dominant pedigree. In this family, non-syndromic symmetric hearing impairment was severest at the high frequencies early, and gradually accumulated all frequencies of hearing. A mutation in DFNA5 leads to a type of hearing loss that closely resembles the frequently observed age-related hearing impairment. It should take into account DFNA5 mutation which the audiogram of a genetic hearing impaired has the same feature.
