从气从痰论治顽固性胃食管反流病

胃食管反流病多因饮食不节、七情失和、素体禀赋虚弱等原因,导致脾胃受损,土壅木郁,肝胃不和,胃失和降,胃气上逆,出现反酸、烧心、嗳气、胃胀等症状。其发生与肝、脾、胃密切相关,气机逆乱,胃失和降是其基本病机。由于本病病程较长,病情易反复发作,易成为顽固性胃食管反流病。而顽固性胃食管反流病多为本虚标实之证,本虚是指因疾病反复发作所导致的脾胃虚弱,标实是指由于脾胃虚弱、脾失健运、土壅木郁、气机不畅所导致的痰湿、气滞、热郁、血瘀等实邪。最后结局是痰气郁(瘀)交阻,脾胃升降失司,胃气上逆,从而引起反酸烧心反复发作,缠绵难愈。纵观核心病机,乃"气郁"、"痰阻"导致的胃失和降、胃气上逆。治疗顽固性胃食管反流病时宜"从气而治""从痰而治"。

Micropulse laser for the treatment of glaucoma: A literature review

Glaucoma, a progressive optic neuropathy, is the leading cause of irreversible blindness worldwide. Glaucoma patients are usually initially managed with medications and laser therapies, before more invasive ocular surgeries. For laser treatments of glaucoma, laser trabeculoplasty and laser transscleral cyclophotocoagulation lower the intraocular pressure by increasing the aqueous outflow and decreasing the aqueous production, respectively. The development of a subthreshold laser technique, the micropulse laser, has been investigated as a potential alternative to traditional glaucoma laser procedures, with an aim to further decrease the risk of side effects without compromising the laser treatments' efficacy. Few reviews have been done on the 2 current micropulse laser treatments for glaucoma—micropulse laser trabeculoplasty and micropulse transscleral cyclophotocoagulation. Hence, the purpose of this review was to assess the efficacy and safety of micropulse laser techniques in the treatment of glaucoma.     

Daratumumab,Bortezomib, and Dexamethasone Versus Bortezomib and Dexamethasone in Patients With Previously Treated Multiple Myeloma: Three-year Follow-up of CASTOR

BackgroundIn the phase III CASTOR study in relapsed or refractory multiple myeloma, daratumumab, bortezomib, and dexamethasone (D-Vd) demonstrated significant clinical benefit versus Vd alone. Outcomes after 40.0 months of median follow-up are discussed.Patients and MethodsEligible patients had received ≥ 1 line of treatment and were administered bortezomib (1.3 mg/m²) and dexamethasone (20 mg) for 8 cycles with or without daratumumab (16 mg/kg) until disease progression.ResultsOf 498 patients in the intent-to-treat (ITT) population (D-Vd, n = 251; Vd, n = 247), 47% had 1 prior line of treatment (1PL; D-Vd, n = 122; Vd, n = 113). Median progression-free survival (PFS) was significantly prolonged with D-Vd versus Vd in the ITT population (16.7 vs. 7.1 months; hazard ratio [HR], 0.31; 95% confidence interval [CI], 0.25-0.40; P < .0001) and the 1PL subgroup (27.0 vs. 7.9 months; HR, 0.22; 95% CI, 0.15-0.32; P < .0001). In lenalidomide-refractory patients, the median PFS was 7.8 versus 4.9 months (HR, 0.44; 95% CI, 0.28-0.68; P = .0002) for D-Vd (n = 60) versus Vd (n = 81). Minimal residual disease (MRD)–negativity rates (10⁻⁵) were greater with D-Vd versus Vd (ITT: 14% vs. 2%; 1PL: 20% vs. 3%; both P < .0001). PFS2 was significantly prolonged with D-Vd versus Vd (ITT: HR, 0.48; 95% CI, 0.38-0.61; 1PL: HR, 0.35; 95% CI, 0.24-0.51; P < .0001). No new safety concerns were observed.ConclusionAfter 3 years, D-Vd maintained significant benefits in patients with relapsed or refractory multiple myeloma with a consistent safety profile. D-Vd provided the greatest benefit at first relapse and increased MRD-negativity rates.     

Molecular profiling of Chinese R-CHOP treated DLBCL patients: Identifying a high-risk subgroup

Diffuse large B-cell lymphoma (DLBCL) is a clinically aggressive and heterogenous disease. Although most patients can be cured by immunochemotherapy, 30% to 40% patient will ultimately develop relapsed or refractory disease. Here, we investigated the molecular landscapes of patients with diverse responses to R-CHOP. We performed capture-based targeted sequencing on baseline samples of 105 DLBCL patients using a panel consisting of 112 lymphoma-related genes. Subsequently, 81 treatment-naïve patients with measurable disease and followed for over 1 year were included for survival analysis. Collectively, the most commonly seen mutations included IGH fusion (69%), PIM1(33%), MYD88 (29%), BCL2 (29%), TP53 (29%), CD79B (25%) and KMT2D (24%). Patients with TP53 mutations were more likely to have primary refractory disease (87.0% vs 50.0%, P = .009). For those with TP53 disruptive mutations, 91.7% patients were in the primary refractory group. Interestingly, BCL-2 somatic hypermutation was only seen in patients without primary refractory disease (P = .014). In multivariate analysis, BCL-2 amplification (hazard ratio [HR] = 2.94, P = .022), B2M mutation (HR = 2.99, P = .017) and TP53 mutation (HR = 3.19, P < .001) were independently associated with shorter time to progression (TTP). Furthermore, TP53 mutations was correlated with worse overall survival (P = .049). Next, we investigated mutation landscape in patients with wild-type (WT) TP53 (n = 58) and found that patients harboring MYD88 L265P had significantly inferior TTP than those with WT or non-265P (P = .046). Our study reveals the mutation spectrum of treatment-naive Chinese DLBCL patients. It also confirms the clinical significance of TP53 mutations and indicates the prognostic value of MYD88 L265P in TP53 WT patients.
