Background::Although the treatment of peripheral T-cell lymphoma (PTCL) has undergone advancements during the past several years, the response rate and long-term effects with respect to patients with PTCL remain unsatisfactory—particularly for relapsed or refractory (R/R) patients. This phase II trial was designed to explore the efficacy and safety of an all-oral regimen of chidamide plus prednisone, cyclophosphamide, and thalidomide (CPCT) for R/R PTCL patients who could not tolerate the standard chemotherapy for a variety of reasons.Methods::We conducted a multicenter phase II clinical trial in which we combined chidamide (30 mg twice weekly) with prednisone (20 mg daily after breakfast), cyclophosphamide (50 mg daily after lunch), and thalidomide (100 mg daily at bedtime) (the CPCT regimen) for a total of fewer than 12 cycles as an induction-combined treatment period, and then applied chidamide as single-drug maintenance. Forty-five patients were ultimately enrolled from August 2016 to April 2021 with respect to Chinese patients at nine centers. Our primary objective was to assess the overall response rate (ORR) after the treatment with CPCT.Results::Of the 45 enrolled patients, the optimal ORR and complete response (CR)/CR unconfirmed (CRu) were 71.1% (32/45) and 28.9% (13/45), respectively, and after a median follow-up period of 56 months, the median progression-free survival (PFS) and overall survival (OS) were 8.5 months and 17.2 months, respectively. The five-year PFS and OS rates were 21.2% (95% confidence interval [CI], 7.9-34.5%) and 43.8% (95% CI, 28.3-59.3%), respectively. The most common adverse event was neutropenia (20/45, 44.4%), but we observed no treatment-related death.Conclusion::The all-oral CPCT regimen was an effective and safe regimen for R/R PTCL patients who could not tolerate standard chemotherapy for various reasons.Trial Registration::ClinicalTrials.gov, NCT02879526.

Objective:To investigate the effect of salvia miltiorrhiza-derived Sal-miR-58 on the radiosensitivity of glioma U251 cells and its possible mechanism. Methods:Glioma U251 cells were treated with different concentrations of miR-Ctl or Sal-miR-58 mimic, and subsequently treated with radiation to establish the radiotherapy model in vitro. The effect of Sal-miR-58 upon U251 cell viability was assessed by MTT assay. The effect of Sal-miR-58 on apoptosis of glioma U251 cells was evaluated by Hoechst33342/ propidium iodide (PI) staining. The changes of reactive oxygen species (ROS) content in U251 cells were detected by 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA) fluorescent probe. The effect of Sal-miR-58 combined irradiation on the radiosensitivity of U251 cells was detected by clone formation assay. The expression levels of HCLS1-related protein X-1 (HAX1), apoptosis marker proteins B cell lymphoma 2 (Bcl-2), cleaved-cysteine-containing aspartate-specific protease (Cleaved-Caspase) 9 and Cleaved-Caspase 3 were detected by Western blot. Multi-group comparison was conducted by one-way ANOVA. Two-group comparison was performed by independent sample t-test. Results:Sal-miR-58 could exacerbate the inhibition of U251 cell proliferation after irradiation ( P<0.05). Sal-miR-58 could promote the apoptosis of U251 cells and increase the production of ROS in U251 cells after radiation ( P<0.05). Clone formation assay showed that Sal-miR-58 increased the radiosensitivity of U251 cells, with a radiosensitization ratio of 1.43. Western blot showed that Sal-miR-58 inhibited the expression of HAX1 in U251 cells. Sal-miR-58 could inhibit the expression of Bcl-2 and increase the activation of Caspase 3 and Caspase 9 by reducing the expression of HAX1. Conclusions:Sal-miR-58 enhances the radiosensitivity of U251 cells. The possible mechanism is that Sal-miR-58 inhibits the expression of HAX1 induced by radiation and accelerates the apoptosis process of tumor cells.

Objective To observe the clinical effect of traditional Chinese medicine bone-setting technique using spinal,pelvi-lower extremity line to treat patients with knee osteoarthritis(KOA).Methods 426 patients with KOA were all from the First Affiliated Hospital of Hebei University of Traditional Chinese Medicine.They were randomly divided into experimental group(384 cases,57 cases of elimination,shedding and termination)by computer generated sequence.Traditional Chinese bone setting techniques were applied with spinal-pelvic-lower limb force line(divided into three parts:lumbar fixed point reduction method,hip joint push-pull and extension method and knee peripheral tendon recovery method every 3 days.2 weeks)treatment;The control group was the waiting treatment group(48 cases,6 cases were eliminated,abscission,termination),which was only used for clinical observation for 2 weeks.The main outcome index was WOMAC pain score.Secondary outcome measures were WOMAC stiffness score,functional score,standardized score and quality of life score(SF-12).The test time points were baseline,2 weeks after enrollment,and follow-up(14 weeks after enrollment).The control group was at baseline and 2 weeks after enrollment.Results Compared with baseline,WOMAC pain score,stiffness score,functional score and standardized score were all decreased in 2 groups 2 weeks after enrollment(P<0.05),but the experimental group was significantly decreased compared with the control group(P<0.001).SF-12 quality of life scores were all higher than before(P<0.001),but the experimental group was significantly higher than the control group(P<0.001).At follow-up,compared with 2 weeks after enrollment,WOMAC pain scores were increased(P<0.001),WOMAC stiffness,joint function and standardized scores were decreased(P<0.001),and SF-12 scores were increased(P<0.001).Conclusion The use of spinal-pelvi-lower extremity line of traditional Chinese medicine bone-setting technique in the treatment of KOA is effective in improving the knee joint function and improving the quality of life of patients,but the short-term effect of pain relief is good,and the long-term effect is not good.Its safety is good,and it can be considered in clinical application for KOA patients with joint dysfunction as the main manifestation.
