Osteoporosis is a prevalent skeletal condition characterized by reduced bone mass and strength, leading to increased fragility. Buqi-Tongluo (BQTL) decoction, a traditional Chinese medicine (TCM) prescription, has yet to be fully evaluated for its potential in treating bone diseases such as osteoporosis. To investigate the mechanism by which BQTL decoction inhibits osteoclast differentiation in vitro and validate these findings through in vivo experiments. We employed MTS assays to assess the potential proliferative or toxic effects of BQTL on bone marrow macrophages (BMMs) at various concentrations. TRAcP experiments were conducted to examine BQTL's impact on osteoclast differentiation. RT-PCR and Western blot analyses were utilized to evaluate the relative expression levels of osteoclast-specific genes and proteins under BQTL stimulation. Finally, in vivo experiments were performed using an osteoporosis model to further validate the in vitro findings. This study revealed that BQTL suppressed receptor activator of NF-κB ligand (RANKL)-induced osteoclastogenesis and osteoclast resorption activity in vitro in a dose-dependent manner without observable cytotoxicity. The inhibitory effects of BQTL on osteoclast formation and function were attributed to the downregulation of NFATc1 and c-fos activity, primarily through attenuation of the MAPK, NF-κB, and Calcineurin signaling pathways. BQTL's inhibitory capacity was further examined in vivo using an ovariectomized (OVX) rat model, demonstrating a strong protective effect against bone loss. BQTL may serve as an effective therapeutic TCM for the treatment of postmenopausal osteoporosis and the alleviation of bone loss induced by estrogen deficiency and related conditions.

ObjectiveTo investigate the effect of anodal transcranial direct current stimulation (atDCS) combined with contralaterally controlled functional electrical stimulation (CCFES) on upper limb motor function of stroke patients. MethodsFrom January to December, 2022, 60 stroke patients from Zhejiang Provincial People's Hospital were randomly divided into atDCS group (n = 20), CCFES group (n = 20) and combined group (n = 20). All the groups accepted routine rehabilitation, while atDCS group accepted atDCS on the primary motor (M1) area of the damaged hemisphere, CCFES group accepted CCFES on the triceps brachii and extensors carpi muscles, and the combined group accepted atDCS on the M1 area of damaged hemisphere and CCFES on triceps brachii and extensors carpi muscles, for six weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Wolf Motor Function Test (WMFT), and the electromyography root mean square (RMS) ratio of bilateral triceps brachii muscles and extensor carpi muscles, before and after treatment. ResultsThe FMA-UE score, WMFT score, and the RMS ratio of the triceps brachii muscles and extensor carpi muscles improved in all the groups after treatment (|t| > 5.007, P < 0.001), and improved the most in the combined group (F > 14.492, P < 0.001). ConclusionatDCS combined with CCFES can effectively improve upper limb motor function of stroke patients.

Eubhorbia neriifolia L. is a plant of Euphorbia family.Five known lignans were isolated from the aerial parts of E. neriifolia L. by silica gel for column chromatography and preparative high-performance liquid chromatography (HPLC).Their potential antitumor activities were evaluated in vitro.Compound 2 exhibited proliferation inhibition and cytotoxicity against esophageal squamous cancer cells, especially KYSE-410 and KYSE-450 cells.Further analyses showed that compound 2 could significantly induce apoptosis through the activation of caspase 3/9 and down-regulation of the Bcl-2/Bax protein ratio.These results suggested that compound 2 had a significant inhibitory effect on the esophageal squamous cancer cells, especially KYSE-410, which deserves further research as a potential antitumor agent.

Objective:To analyze the efficacy and safety of Daratumumab for the treatment of primary AL light chain systemic amyloidosis.Methods:Twenty one patients who were diagnosed as primary AL light chain systemic amyloidosis and treated with Daratumumab from 7 centers were retrospectively analyzed. Daratumumab was administrated as first line therapy in seven patients and 14 patients with relapsed settings. Hematological response, safety and survival were analyzed.Results:All 7 patients achieved very good partial response (VGPR) or better with first-line application of daratumumab. Three patients died, and the other four achieved organ remission. Among 14 relapsed patients, 2 patients had a difference of free light chain (dFLC) less than 20 mg/L before treatment, and 9 with a dFLC of more than 50 mg/L. All patients reached partial response (PR) or better, including 4 patients with complete response (CR), 3 with VGPR and 2 with PR. The response rate was 100% in 3 patients with dFLC 20-50 mg/L at baseline. The organ remission rate was 50% in patients with heart involvement and 58.3% in patients with kidney impairment. The overall median follow-up period was 5.3 months, and 11 months in surviving patients. One patient died of severe infection and disseminated intravascular coagulation (DIC) with stable amyloidosis. One patient switched to other regimens because dFLC elevated but did not fulfill progressive disease after 2 year application. As to safety, no grade 3/4 infusion reaction developed, and grade 1 infusion reaction occurred in 3 cases during the first infusion. Lymphocytopenia was seen in 75% patients including grade 3 or more in 30% patients.Conclusion:Daratumumab is effective to eliminate serum free light chain in both newly diagnosed and relapsed patients with systemic amyloidosis.

Objective:To build a medical service experience system based on role play of hospital staff, and explore its contribution to upgrading medical service, elevating medical service quality, and improving patients′ satisfaction.Methods:An indicator system for medical service experience was developed via literature review. 20 newly recruited hospital employees in 2019 were sampled randomly to form a service experience team, who were arranged to experience the full medical service process of outpatients and inpatients based on role play. The questionnaire for service quality based on patient perception and expectation was used to survey the expectation and perception values of those role players on their medical service experiences, and summarize the defects found on such six dimensions as hospital reliability, responsiveness, tangibility, assurance, empathy and cost-effectiveness. After due corrections of these defects, further experiences and patient satisfaction survey were made to assess the effects of such actions taken. Paired t test was used respectively in statistical analysis of service experience value and actual perception value, as well as the perception values before and after the actions taken, and χ2 test was used for a statistical analysis of patient satisfaction. Results:Role players experienced respectively at the emergency, outpatient and inpatient departments of the hospital for a week in August 2019. Statistics of their experiences indicated≥0.50 points difference between the mean expectation and perception values on doctor-patient communication, patient help responsiveness, outpatient process, examination report delivery duration, service attitude, patient trust on medical workers, medical environment and patient privacy protection.Following a 3-month reform, role players found improvements in such aspects as hospital reliability, responsiveness, tangibility, assurance, empathy and cost-effectiveness; patient satisfaction improved sizably in December 2019 over January of the same year( P<0.05). Conclusions:The construction and application of the medical service experience system based on role play of hospital staff prove highly useful in upgrading medical service actions, improving medical service quality, and improving patient satisfaction.
