【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 develop a score system to predict the probability of failure of monotherapy in epilepsy patients with initial treatment, and then provide pillars for early use of polytherapy.MethodsThis is a retrospective analysis of the clinical data of 189 patients with epilepsy treated in Department of Neurology, the Third Xiangya Hospital of Central South University from January 2019 to July 2020. Patients were divided into monotherapy acceptable group and monotherapy poor effect group according to their drug treatment plan and drug efficacy. The influencing factors were screened out by single factor analysis and binary logistic regression analysis. And on the basis of this β value, a quantitative scoring table for predicting the unsatisfying treatment effect of monotherapy is developed. And the receiver operating curve (ROC curve) was used to evaluate the effectiveness of the scale.ResultsBased on a standard of 75% reduction in seizures during the observation period, 138 cases (73%) were effective with monotherapy plan, while 51 cases (23%) were unsatisfactory. Regression analysis showed that multiple forms of seizures, status epilepticus (t2), brain damage, and the number of seizures ≥ 7 times before treatment are independent risk factors for poor outcome of monotherapy. The resulting score sheet has a total score of 12 points; the area under the ROC curve is 0.779, and the critical score is 6 points (sensitivity: 0.314; specificity: 0.957). Patients with more than this score have a strong probability of poor response in monotherapy.ConclusionThis prediction model can effectively assess the risk of unsatisfactory therapeutic effect of monotherapy in epilepsy patients who are initially treated, and thus has reference function for the early selection of polytherapy.
ObjectiveTo investigate the working principles, recent advances, and combined therapeutic efficacy of irreversible electroporation (IRE) in pancreatic cancer treatment when integrated with conventional therapies (e.g., surgery, chemotherapy, radiotherapy, immunotherapy), and to evaluate its potential for improving patient survival outcomes and quality of life. MethodsA comprehensive analysis of recent IRE researches in pancreatic cancer was performed, elucidating therapeutic mechanisms, technical merits, clinical limitations, and combinatorial effects with conventional therapies through examination of clinical trials and prospective studies. ResultsIRE induces irreversible nanopores in tumor cell membranes via high-intensity electric fields, disrupting membrane integrity and triggering apoptotic cell death. Notably, it promotes immunogenic cell death, activating dendritic cells and initiating tumor-specific immune responses. When combined with surgery, chemotherapy, radiotherapy, or immunotherapy, IRE enhances therapeutic efficacy, prolongs survival in locally advanced pancreatic cancer patients, reduces postoperative recurrence rates, and significantly improves quality of life. ConclusionsAs a non-thermal ablation technique, IRE demonstrates unique advantages in localized pancreatic cancer treatment, particularly for surgically ineligible patients, and serves as a potent adjunct to traditional therapies. With technological refinements and accumulating clinical evidence, IRE is poised to play an increasingly pivotal role in future oncology practice.

ObjectiveTo systematically evaluate the efficacy of steroids combined with antiepileptic drugs compared with alone antiepileptic drugs in the treatment of children with epileptic electrical status during sleep to provide evidence-based medical basis for its treatment.MethodsElectronic searches were maded in PubMed, Embase database, Cochrane Library, CNKI, Wanfang and the Chinese biomedical literature database for the literature about steroids combined with antiepileptic drugs compared with alone antiepileptic drugs in the treatment, and retrieval time is from January 1990 to October 2020. Two evaluators independently screened literature, extracted data, evaluated literature quality and risk of bias and checked each other. Meta analysis was performed by stata16.0 software.ResultsA total of 679 children with ESES were included in 10 studies, including 9 randomized controlled trials and 1 retrospective cohort study. Meta analysis results showed that there were statistically significant differences in clinical improvement rate [RR=1.31, 95%CI (1.21, 1.42), P<0.01], electroencephalogram discharge improvement rate [RR=1.35, 95%CI (1.25, 1.46), P<0.01] and cognitive intelligence score [SMD=1.19, 95%CI (0.80, 1.57), P<0.01] between steroids combined with antiepileptic drugs group and alone antiepileptic drugs group after 6 months follow-up. The incidence of adverse reactions in steroids combined with antiepileptic drugs group was higher than that in alone antiepileptic drugs group, and the difference was statistically significant [RR=4.13, 95%CI (1.06, 16.13), P<0.01]. All adverse reactions improved or disappeared after drug withdrawal.ConclusionCompared with alone antiepileptic drugs, steroids combined with antiepileptic drugs group has advantages in controlling epileptic seizures, improving electroencephalogram abnormalities and improving cognitive ability, and it is relatively safe.
