Pyridoxine Is Effective for Preventing Hand-Foot Syndrome Induced by Pegylated Liposomal Doxorubicin for Multiple Myeloma: The Results of a Randomized Study.

PURPOSE: Pegylated liposomal doxorubicin (PLD) is highly effective for treating multiple myeloma (MM). Hand-foot syndrome (HFS) is a dose-limiting adverse event of PLD that may reduce a patient's quality of life or prevent certain patients from receiving PLD. Several researchers have discovered that pyridoxine, an activated form of vitamin B6, may prevent PLD-associated HFS. We designed a prospective randomized trial to examine whether prophylactic pyridoxine might prevent the incidence or delay the occurrence of PLD-induced HFS in patients with MM. METHODS: Patients who met the trial's eligibility requirements were randomized and then administered either pyridoxine 100 mg twice daily or no pyridoxine, in both cases accompanied by their PLD-containing chemotherapeutic agent. Follow-up of patients was performed until the completion of induction therapy, the development of HFS or disease progression. RESULTS: Between January 1, 2017, and January 1, 2019, 105 patients were randomly assigned to the pyridoxine group (n = 52) or the no pyridoxine group (n = 53). In the pyridoxine and no pyridoxine groups, HFS developed after a median of 4 (range, 1-8 cycles) and 3 (range, 1-7 cycles) chemotherapeutic cycles, respectively. There were no grade 3 incidents recorded. Overall, 13.3% of patients experienced HFS. A 11 of 53 (20.8%) patients in the no pyridoxine group experienced HFS, compared to 3 of 52 (5.8%) patients in the pyridoxine group (P = .042); there was no difference in HFS grades (P = .725). CONCLUSIONS: The findings of benefit from prophylactic pyridoxine in this open-label trial have suggested its promise as a treatment for reducing HFS in MM patients. Further research with a placebo-controlled design is recommended. CLINICAL TRIAL REGISTRATION: ChiCTR2100050294.

Professor's clinical experience in the treatment of premature ovarian failure withacupuncture technique and Chinese herbal medicine / 中国针灸

In the treatment of premature ovarian failure (POF), professorfocuses on the determination of syndrome to seek for etiology, associating with the differentiation of meridian and collateral and that oforgans. Professorbelieves that POF is mainly manifested as amenorrhea and infertility, localized in the kidney, with the dysfunction of liver, spleen and heart. It is impacted by many pathological factors, such as cold blockage,stagnation, blood stagnation, blood deficiency,deficiency, etc., which leads to the damage of the thoroughfare vessel and the conception vessel and the blockage of menstrual flow. On the basis of four diagnostic Methods and syndrome differentiation, there are four common syndromes of POF, namedand blood deficiency,and blood stagnation, liver and kidney deficiency anddeficiency of spleen and kidney.acupuncture technique is summarized by Professoron the basis oftheory. It is an effective and scientific method for acupoint selection along the meridians. The acupoints on the back, communicating with the governor vessel and mind regulation, acting on the brain are selected to promoteof the governor vessel. The back-points of fiveorgans are selected to regulate the functions of internal organs. The acupoints on the abdomen and the conception vessel are selected to conduceto the primary so as to improve reproductive function. In the guidance ofacupuncture technique, the acupoint prescription is formed and the Chinese herbal medicines are selected in combination to improve ovarian function and regulate menstruation. Hence, the satisfactory therapeutic effects have been achieved.

Regulation of Transforming Growth Factor -beta 1/Smad3 Signaling Pathway of Asthmatic Rat Airway Remodeling Model by Back Three-acupoint Electroacupuncture / 广州中医药大学学报

Objective To observe the effect of electroacupuncture on back three-acupoints ( namely bilateral Dazhu, Fengmen, Feishu) on the protein and mRNA expression of transforming growth factor-beta 1 (TGF-β1) and Smad3 in asthmatic rat airway remodeling model, and to explore its therapeutic efficacy and molecular mechanism. Methods Rat asthma model was established by inhalation of ovalbumin. After sensitization for 6 weeks, rats were killed. And then the airway morphological parameters of rats were measured by image analysis. The protein and mRNA expression of TGF-β1 and Smad3 in lung tissues were detected by immunohistochemistry and real-time quantitative polymerase chain reaction (qRT-PCR) respectively. Results Compared with the blank group, the standardized values of muscle cross-sectional area including airway smooth muscle area (WAm) /perimeter of the basement membrane (Pbm), and bronchial inner wall area (WAi)/Pbm were increased in the model group. The protein and mRNA expression levels of TGF-β1 and Smad3 were also increased in the model group. In electroacupuncture group, the above observation indexes were decreased, and the differences were statistically significant ( P<0.05 compared with the model group). Conclusion The experimental results indicated that back three-acupoint electroacupuncture has an effect on remodeling airway, and one of the mechanisms is probably associated with the regulation of TGF-β1/Smad3 signaling pathway.
