OBJECTIVE: To investigate the therapeutic effects of 894 coblation-assisted treatment in adult with obstructive sleep apnea-hypopnea syndrome. METHOD: A review of 894 coblation-assisted treatment in adult with obstructive sleep apnea-hypopnea syndrome was presented with respect to the sleep monitoring results, SF-36 health questionnaire survey, therapeutic effects and complications. RESULT: After operation for 6 months, the patients' sleep Monitoring results were improved remarkably (P<0. 01) and their symptoms of snore or choke got improved. SF-36 health questionnaire survey showed that social function, energy and mental health dimension scores were significantly higher than the preoperative (P<0. 05). There were 18 patients suffered Secondarily bleeding within 2 weeks and 23 patients recrudesced within 1 year. CONCLUSION Radio frequency coblation is an applicable method of therapy for patients with obstructive sleep apnea-hypopnea. The treatments differ with the obstructive location and character of upper airway.

To explore and compare the response of the protease inhibitors or non-nucleoside reverse transcriptase inhibitors-based therapeutic impact on metabolic indices in hepatitis C virus (HCV)/human immunodeficiency virus(HIV) co-infected patients.A randomized,open,and control approach was performed to enroll 273 cases of HCV/HIV co-infected patients on their initial visits and to choose protease inhibitors(PIs group) or non-nucleoside reverse transcriptase inhibitors (NNRTIs group) based therapy treatments for one year.Laboratory results of metabolic indices before and after the treatment were collected.After treatment,the levels of triglyceride in NNRTIs and Pls groups were (1.93 ± 0.99) mmol/L and (1.62 ± 0.93) mmol/L respectively,high density lipoprotein-cholesterol were(1.28 ± 0.55) mmol/L and (1.08 ± 0.53) mmol/L,low density lipoprotein-cholesterol were (2.60 ± 1.44) mmol/L and (2.22 ± 1.16) mmol/L,fasting plasma glucose were (5.92 ± 1.21) mmol/L and (4.79 ± 0.47) mmol/L,serum creatinine were (70.5 ± 14.6) μmol/L and (56.6 ± 8.3) μmol/L,and serum amylase were(66.9 ± 27.5) U/L and(62.7 ± 33.8) U/L respectively.The difference between the two groups was statistically significant(all P＜0.01).There is a therapeutic impact on metabolic indices in patients wtih HCV / HIV co-infection after non-nucleoside reverse transcriptase inhibitors-based regimen.

Objective To study the application of contrast-enhanced ultrasonography (CEUS) in the evaluation of the stability of carotid atherosclerotic plaque (CAP).Methods 162 patients with CAP were selected as study group.Meanwhile,34 patients with carotid artery strong echo plaques were selected as control group.The color doppler ultrasound was used to observe the CAP.Results The proportions of lipid type,fiber type,calcification and ulcer plaque in the study group were 21.60%,33.33%,34.57% and 10.37%,which were higher than those of the control group (5.88%,2.94%,2.94% and 2.94%),the differences were statistically significant (χ2=4.537,12.859,13.629 and 3.855,all P<0.05).There were 75 patients of soft plaques,36 patients with mixed plaques,51 patients with hard plaque in 162 patients.The new blood vessels classification in soft plaque group (36.00%,45.33% and 10.33%) were higher than the mixed plaque (30.56%,41.67% and 8.33%) and hard plaque group (31.37%,13.72% and 7.84%).The peak intensity (-86.41±7.81) %,tmax (8.34±1.62)s,mean transit time (24.18±8.67)s in the soft plaque group were significantly lower than the mixed plaque [(-100.73±6.52)%,(9.79±2.14)s and (28.93±9.11)s] and hard plaque patients [(-104.14±6.15)%,(10.23±2.33)s and (30.07±9.48)s],the differences were statistically significant (t=9.518,6.966,2.658,13.592,5.374 and 3.064,all P<0.05),but there were no statistically significant differences between mixed plaque and hard plaque (all P>0.05).The plaque diameter (4.13±0.75)mm diagnosed by CEUS was significantly larger than that of conventional ultrasound [(3.62±1.14)mm],the difference was statistically significant (t=4.757,P=0.000).Conclusion The CEUS can qualitatively detect the atherosclerotic plaque angiogenesis,can quantitatively assess plaque,evaluate the stability of the plaques,and the sensitivity is high.

Objective To evaluate the relationship between serum level of hepatitis C virus (HCV) core protein and antiviral therapy response in patients with hepatitis C. MethodsOne hundred and sixty-two consecutive patients with chronic hepatitis C (CHC) were retrospectively analyzed. Serum level of HCV core protein and HCV RNA were measured. Among them, 35 CHC patients treated with pegylated interferon (PEG-IFN)+ ribavirin (RBV) were followed up before and at week 4, 24, 48 of treatment. The correlations between serum HCV core protein level, HCV RNA and antiviral therapy were evaluated. Comparison between groups was done by t test and comparison of paired data among groups was done by analysis of variance. Results Total 162 patients were divided into six groups according to the HCV virus load: 56 with HCV virus load≤1×103 IU/mL and HCV core protein absorbance (A)=0. 100±0. 029; 9 with 1×103 IU/mL＜ HCV virus load≤1 × 104 IU/mLand A=0. 246±0. 213; 11 with 1 × 104 IU/mL＜ HCV virus load≤1 × 105 IU/mL and A=0. 235±0.179; 28 with 1×105 IU/mL＜ HCVvirusload≤1×106 IU/mL and A=0. 422±0. 319; 51 with 1 × 106 IU/mL＜ HCV virus load≤ 1 × 107 IU/mL and A = 0. 603 ± 0. 330 ; 7 with 1 × 107 IU/mL＜HCV virus load≤ 1 × 108 IU/mL and A = 0. 900± 0. 379. The HCV core protein absorbance was positively correlated with HCV RNA level (r= 0.36, P＜0.05). The HCV core protein absorbance values of 35 CHC patients before therapy, at week 4, 24, and 48 of therapy were 0. 564 ±0. 296,0. 144±0. 062, 0. 091 ±0. 035 and 0. 112±0. 103, respectively. The HCV core protein absorbance values at week 4, 24, 48 all decreased significantly compared with that before therapy (t= 8. 563,9. 195, 9. 250; all P＜0.05), and there was significant difference between those at week 4 and week 24 (t=4. 301, P＜0.05). Conclusion Serum HCV core protein level is closely correlated with HCV viral load during HCV infection process and antiviral treatment.

BACKGROUNDTo elucidate relationship between amino acid sequence of non-structural protein 5A (NS5A) and outcome of HCV (1 b) patients after interferon (IFNa) therapy.

METHODSSera of 24 patients were collected before, during and after IFNa therapy. Pretreatment RNA levels and the sequences of HCV NS5A interferon sensitivity determining region (ISDR) were determined. NS5A full-length sequences of 5 HCV isolates from 3 patients with different response types were also analyzed. Phylogenetic tree analysis and protein secondary structure prediction were undertaken.

RESULTSPretreatment RNA levels of sustained response group were significantly lower than that of non-response group and relapse group (4.50X104 copies/ml versus 1.82X107 copies/ml, P < 0.01).ISDR sequences of NS5A from pretreatment sera were compared with HCV-J strain (prototype). Thirteen of 24 isolates were wild type,11 of 24 were intermediate type and none of them was mutant type. 3 of 6 sustained responders were infected with wild-type isolates, the rest with intermediate type isolates. Phylogenetic tree based on NS5A full-length sequences classified 5 isolates with 3 different response types into 3 groups. Non-response isolates belonged to the same group as HCV-J. Secondary structure prediction of 5 isolates revealed significant differences existing in 2 255- 2 289. This region was partly overlapped with PKR-binding domain.

CONCLUSIONSLow HCV RNA levels in serum are associated with favorable outcome of IFNa therapy. ISDR sequence alone could not predict outcome of IFN treatment. Combination of determination of HCV RNA levels in serum with sequence analysis of PKR-binding domain may be helpful in predicting the efficacy of IFN therapy.

OBJECTIVE To explore the role of adenoidectomy in the treatment of pediatric secretory otitis media.METHODS 120 cases of children diagnosised with secretory otitis media and adenoid hypertrophywho came to our department between January 2013 and May 2015 were devided into 4 groups,30 cases in each group.Group 1 only got drug therapy;Group 2 got adenoidectomy combined with drug therapy;Group 3 got paracentesis or tympanostomy tube;Group 4 got paracentesis or tympanostomy tube,with adenoidectomy at the same time.RESULTS 1.The difference incurative time and recurrence rate were statistically significant between group 1 and group 2.2.There was no statistical difference in healing time but statistical difference in recurrence rate between group 3 and group 4.CONCLUSION For children with secretory otitis media and adenoid hypertrophy,adenoidectomy can shorten the cure time and reduce the recurrence rate at the same time.

Hepatitis B virus (HBV) infection is closely associated with the adverse events such as liver cirrhosis, liver cancer, and liver failure and remains a serious threat to human health. Pegylated interferon is an indispensable drug for the treatment of chronic hepatitis B (CHB), and interferon-stimulated genes are associated with a variety of viruses, but few studies have mentioned their association with hepatitis B and their predictive effect after the treatment of hepatitis B with interferon. This article introduces the predictive factors for interferon treatment of CHB and summarizes the association of interferon-stimulated genes with hepatitis B and their predictive effect, so as to provide a reference for clinical work and basic research.

Objective:To investigate the changes of inflammation and immune function in children with chronic tonsillitis after tonsillotomy. Methods:Prospectively collected 60 children with obstructive sleep apnea （OSA） diagnosed as chronic tonsillitis with adenoids and tonsillar hypertrophy from January to June 2021. Two groups were divided, the experimental group （n=30） underwent bilateral partial tonsillectomy + adenoidectomy by hypothermia plasma ablation, and the control group （n=30） underwent adenoidectomy by using the same hypothermia plasma ablation method. The number of tonsillitis attacks before surgery and within one year after surgery was recorded, and the serum immunoglobulin IgM, IgG, IgA, complement C3 and complement C4 levels before operation, one month and three months after operation were measured. Results:The number of tonsillitis attacks in the experimental group and the control group at one year after surgery was lower than that before surgery（P<0.05）; The number of inflammatory attacks in the experimental group was （0.50±0.63） times/year, which was lower than that of （1.33±0.80） times/year in the control group. There was no significant difference in the five immunization results of the two groups at one month and three months after operation compared with before operation, and there was also no significant difference between the experimental and the control groups. Conclusion:Partial tonsillectomy can be applied to children with chronic tonsillitis, which can effectively reduce the number of tonsillitis attacks and has no effect on the immune function of children.
