Methods Twenty-six HBeAg-positive CHB patients received initial treatment of ADV from January 2006 to December 2010, and their serum HBV-DNA still maintained over or equal to 1.0×104 copies/mL after 48 weeks. These patients received the optimized treatment of ADV (10 mg, one time per day) combined with LAM (100 mg, one time per day). Patients′ responses to the treatment at the 12th and 24th week were observed. Results Compared with baseline, ADV plus LAM had an improved response rate of virological response, biochemical response and HBeAg/HBeAb seroconversion. No LAM-resistant or ADV-resistant mutations were detected. In all the 26 patients, no adverse reactions were observed. Conclusion Optimized therapy combining LAM and ADV can be a good choice for patients with hepatitis B who have a poor response to ADV monotherapy.
【Abstract】Objective To investigate therapeutic effect and mechanism of hyperbaric oxygen and ulinastatin respectively or combinatively used to treat acute necrotizing pancreatitis (ANP). Methods One hundred and twenty SD rats were divided into 6 groups randomly: group of normal control, group receiving sham operation, group of untreated acute necrotizing pancreatitis (ANP group), group of acute necrotizing pancreatitis treated with hyperbaric oxygen (HBO group), group of acute necrotizing pancreatitis treated with ulinastatin (ULT group), and group of acute necrotizing pancreatitis treated with combined hyperbaric oxygen and ulinastatin (HBO+ULT group). The rat model of acute necrotizing pancreatitis was established according to Aho HJ et al. Concentrations of amylase, TNFα, TXB2 and 6ketoPGF1α in blood were measured through ELISA or radioimmunoassay. Changes of pancreatic histopathology were investigated. SPSS 10.0 was used in statistical analysis. Results The concentrations of amylase, TNFα, TXB2 in the ANPtreated groups were significantly lower than those of ANP group (P＜0.01) except for 6ketoPGF1α and the levels of amylase and TNFα of HBO group were strikingly higher than those in HBO+ULT group. Only the level of AMS was significantly different between ULT group and HBO+ULT group (P＜0.01). Pancreas histopathological scores(HS) and CD8 counts of ANP group were significantly higher than those the other three group, but CD4 counts and CD4/CD8 ratio were on the contrary (P＜0.05). HS of HBO and ULT were strikingly higher than those of HBO+ULT (P＜0.05).Conclusion ①Hyperbaric oxygen or ulinastatin can effectively decrease the blood levels of enzymes and cytokines and improve the pancreatic immunity. ②Hyperbaric oxygen in combination with ulinastatin are more effective than either of them in the treatment of ANP.

Methods A total of 26 HBeAg-positive patients with suboptimal response to adefovir dipivoxil (treated with adefovir dipivoxil for more than 12 months) were treated with adefovir dipivoxil 10 mg in addition to telbivudine 600 mg between June 2008 and August 2009. Liver function and serum hepatitis B virus (HBV) DNA tests were assessed at the baseline and 3-month intervals, whereas HBV serological markers and abdominal ultrasonography were carried out every 6 months. Results During the first year of treatment, all patients showed a progressive decline of serum HBV DNA levels; while undetectable serum HBV DNA and normalization of alanine aminotransferase was achieved in 24(92.3%) and 25 (96.2%) patients, respectively, at the end of the first year of treatment. The 6- and 12-month cumulative rates of HBeAg loss were 26.9% (7/26) and 42.3% (11/26), respectively; and corresponding cumulative rates of HBeAg/anti-HBe seroconversion were 7.7% (2/26) and 30.8 (8/26), respectively. During the observation period, no virological breakthrough was detected. Conclusion Telbivudine combined with defovir dipivoxil may be a good choice for patients with suboptimal response to adefovir dipivoxil, which could induce effective viral inhibition and help patients obtain more virological, biochemical and immunological responses.
Objective To explore whether hospitalized elderly patients with severe communityacquired pneumonia ( SCAP) have better outcomes if they are treated with dual-therapy consisting of a β-lactam/macrolide or fluoroquinolone.Methods A prospective study was conducted in patients with SCAP aged 65 years or older between January 2007 and January 2012. These patients were assigned to a combination therapy group or a β-lactam monotherapy group by the attending physicians. Time to clinical stability( TCS) and total mortality were calculated. Prognostic factors for death were analyzed. Results Among the 232 patients, 153 patients were given β-lactam/macrolide or β-lactam/ fluoroquinolone ( macrolide in 67 patients and fluoroquinolone in 86) , while 79 were treated with β-lactam monotherapy. Compared with the monotherapy group, the combination therapy group was associated with significant decreased TCS ( median TCS, 10 days vs. 13 days) , and lower overall in-hospital mortality( 24.2% vs. 43.0%, P lt;0. 01) . Compared with fluoroquinolone, macrolide use was associated with lower ICU mortality ( 14.9% vs. 31.4% , P lt;0. 01) . Simplified acute physiology score Ⅱ, pneumonia severity index, mutilobar infiltration, and β-lactam monotherapy were confirmed as independent predictors of death. Conclusion β-lactam/macrolide or β-lactam/ fluoroquinolone combination therapy, especially with macrolide, has superiority over β-lactam monotherapy in elderly patients with SCAP, and should be recommended.
ObjectiveTo observe the long-term effects of anti-vascular endothelial growth factor (VEGF) drug initiation combined with dexamethasone intravitreal implant (DEX) on the structural integrity of the outer macular region of the eye in patients with macular edema (ME) secondary to central retinal vein occlusion (CRVO). MethodsA retrospective clinical study. From February 2018 to August 2022, 54 patients diagnosed with CRVO combined with ME (CRVO-ME) in Department of Ophthalmology of Central Theater Command General Hospital were included in the study. Among them, there were 30 males and 24 females, all with monocular disease. According to different treatment regiments, patients were divided into anti-VEGF and DEX combination therapy group (initial combination group), anti-VEGF drug monotherapy group (monotherapy group) with 21 eyes and 33 eyes, respectively. Best corrected visual acuity (BCVA), optical coherence tomography (OCT) examination were performed in all eyes. The thickness of foveal retina (CRT) and the deficiency length of outer membrane (ELM), ellipsoid band (EZ) and chimaera band (IZ) in the 1 mm macular area were measured by OCT. The initiating combination group was treated with anti-VEGF agents or DEX as assessed on demand (PRN) after the combination therapy, and the monotherapy group received 3+PRN regimen. Relevant examinations were performed at 1 (V1), 6 (V6), 12 (V12) months and observation cut-off or the last visit (Vf) after treatment using the same equipment before treatment. The deletion length of ELM, EZ and IZ in V1, V6, V12 and Vf after treatment were compared between the two groups. Repeated measurement ANOVA was used to compare BCVA, CRT and deletion length of ELM, EZ and IZ at different follow-up times. Spearman rank correlation test was used to analyze the correlation between the two groups of continuous variables. ResultsThe follow-up time of patients in the initial combination group and monotherapy group was (18.05±5.66) and (21.90±10.80) months, respectively, with no statistical significance (F=13.430, P=0.229). Compared with baseline, the deletion lengths of ELM, EZ and IZ were significantly improved (F=11.848, 10.880, 29.236), BCVA was increased (F=10.541) and CRT was decreased (F=52.278) in the initial combination group and the monotherapy group at different follow-up times after treatment. The differences were statistically significant (P＜0.001). At V1, EZ and IZ deletion lengths were (344.10±413.03), (593.33±372.96) μm and (354.71±321.75), (604.85±385.77) μm in the initial combination group and monotherapy group, respectively. The improvement of EZ and IZ deletion lengths in the initial combination group was better than that in the single drug group, and the difference was statistically significant (F=5.272, 6.106; P=0.026, 0.017). The CRT of the initial combination group and the monotherapy group were (248.86±59.99) and (314.72±214.91) μm, respectively, and the CRT of the initial combination group was significantly lower than that of the monotherapy group, with statistical significance (F=6.102, P=0.017). At V6, V12 and Vf, the deletion length of ELM, EZ and IZ and BCVA and CRT showed no statistical significance (P＞0.05). Correlation analysis showed that ELM, EZ, IZ were positively correlated with BCVA and CRT in the initial combination group and monotherapy group (P＜0.001). In V6, V12 and Vf, the number of anti-VEGF drug injections in the initial combination group and monotherapy group was (2.67±1.32), (4.43±2.27), (6.05±3.51), (4.58±0.90), (7.33±1.93), (11.33±6.10) times, respectively. The number of injections in the initial combination group was significantly lower than that in the monotherapy group, and the difference was statistically significant (F=5.150, 0.646, 3.433; P＜0.001). ConclusionsThe improvement of BCVA and CRT in the initial combination group is similar to that in the monotherapy group. Compared with the monotherapy group, EZ and IZ deletion are improved more significantly in the initial combination group, and CRT decreased more rapidly and significantly. The initial combination group receives fewer anti-VEGF injections than the monocular group.
ObjectiveTo observe the short-term efficacy and safety of a new strategy of dexamethasone intravitreal implant (DEX) combined with ranibizumab in the treatment of retinal vein occlusion (RVO) secondary to macular edema (ME) (RVO-ME). MethodsA prospective clinical interventional study. From May 2020 to September 2021, 78 RVO-ME patients with 78 eyes diagnosed in the eye examination of Department of Ophthalmology of The First Affiliated Hospital of Anhui University of Science&Technology were included in the study. Among them, there were 35 males and 43 females, all with monocular disease. Branch retinal vein occlusion (BRVO) was found in 40 patients with 40 eyes; central retinal vein occlusion (CRVO) was found in 38 patients with 38 eyes. According to the treatment strategies, patients were randomly divided into DEX and ranibizumab combination therapy group (initial combination therapy group), DEX monotherapy group and ranibizumab monotherapy group, with 29 eyes, 26 eyes and 23 eyes respectively. Different types of RVO were divided into different treatment groups of BRVO and CRVO. Best corrected visual acuity (BCVA) and frequency domain optical coherence tomography were performed. The BCVA examination was carried out using the international standard visual acuity chart, which was converted into the logarithmic minimum angle of resolution (logMAR) visual acuity during statistics. There were no significant differences in logMAR BCVA (χ2=2.376) and central retinal thickness (CRT) (F=0.052) among the three groups (P＞0.05). After treatment, the patients were followed up every month for 6 months. The changes of BCVA, CRT and the incidence of adverse reactions were observed during follow-up. One-way ANOVA and Kruskal-Wallis H test were used to compare the differences. ResultsDuring the follow-up period, compared with the baseline, the BCVA of the eyes in the initial combination treatment group, DEX treatment group and ranibizumab treatment group were significantly improved (Z=110.970, 90.359, 207.303), and CRT was significantly decreased (F=107.172, 88.418, 61.040), the difference was statistically significant (P＜0.01). At 1, 2, 3, 4, 5, and 6 months after treatment, there were significant differences in the mean changes in BCVA between the initial combined treatment group, DEX treatment group, and ranibizumab treatment group (χ2=34.522, 29.570, 14.199, 7.000, 6.434, 6.880; P＜0.05); 1, 2, 3, and 6 months after treatment, the differences were statistically significant (F=4.313, 7.520, 3.699, 3.152; P＜0.05). The time required to improve BCVA by 0.1 logMAR units in the initial combination treatment group, DEX treatment group, and ranibizumab treatment group was 5.73 (3.21, 8.48), 9.97 (6.29, 18.78), and 20.00 (9.41, 37.89) d, respectively; The time required for CRT to drop to 300 μm was 24.31 (21.32, 26.15), 29.42 (25.65, 31.37), and 29.17 (25.28, 36.94) d, respectively. The BCVA improvement of 0.1 logMAR unit and the time required for CRT to decrease to 300 μm in the eyes of initial combined treatment group were shorter than those in the eyes of DEX treatment group and the ranibizumab treatment group, and the differences were statistically significant (Z=－3.533, －4.445, －3.670, －4.030; P＜0.01). Different BRVO treatment groups: 1, 2, 3, 5, and 6 months after treatment, the mean BCVA changes were significantly different (χ2=24.989, 21.652, 11.627, 7.054, 9.698; P＜0.05); CRVO was different treatment group: 1 and 2 months after treatment, there were significant differences in mean BCVA changes (χ2=11.137, 9.746; P＜0.05). Two months after treatment, there were significant differences in CRT changes between BRVO and CRVO groups with different treatment regimens (F=3.960, 3.722; P＜0.01). The time required to improve BCVA by 0.1 logMAR unit in the eyes of BRVO and CRVO combined treatment group was shorter than that in the eyes of BRVO, CRVO DEX treatment group and the BRVO, CRVO ranibizumab treatment group, and the differences were statistically significant (BRVO: Z=－2.687, －3.877; P＜0.05; CRVO: Z=－2.437, －3.575; P＜0.05). The time required for CRT to drop to 300 μm in the CRVO combined treatment group was significantly shorter than that in the CRVO DEX treatment group and the CRVO ranibizumab treatment group, and the difference was statistically significant (F=6.910, P＜0.010); there was no statistically significant difference between the different BRVO treatment groups (F=1.786, P＞0.05). The number of re-treated eyes in the initial combined treatment group and DEX treatment group was less than that in the ranibizumab treatment group, and the difference was statistically significant (χ2=18.330, 7.224; P＜0.05). The retreatment interval of the eyes in the initial combined treatment group was significantly longer than that in the DEX treatment group and the ranibizumab treatment group, and the difference was statistically significant (P＜0.01). There was no significant difference in the incidence of intraocular hypertension among the initial combined treatment group, DEX treatment group and ranibizumab treatment group (χ2=0.058, P＞0.05). ConclusionsThe new strategy of initial combination therapy with DEX and ranibizumab in the treatment of RVO-ME has a better short-term effect. Compared with the monotherapy group, the retreatment interval is shorter, the visual and anatomical benefits are faster, the efficacy lasts longer, and the safety is better.
