Combined immune score predicts the prognosis of newly diagnosed multiple myeloma patients in the bortezomib-based therapy era.

ABSTRACT: To investigate the effect of a combined immune score including the lymphocyte-to-monocyte ratio (LMR) and uninvolved immunoglobulin (u-Ig) levels on the prognosis of newly diagnosed multiple myeloma (NDMM) patients treated with bortezomib.Clinical data of 201 NDMM patients were retrospectively analyzed. Patients with LMR ≥ 3.6 and LMR < 3.6 were scored 0 and 1, respectively. Patients with preserved u-Ig levels, suppression of 1 u-Ig, and suppression of at least 2 u-Igs were scored 0, 1, and 2, respectively. The immune score, established from these individual scores, was used to separate patients into good (0-1 points), intermediate (2 points), and poor (3 points) risk groups. The baseline data, objective remission rate (ORR), whether receive maintenance treatment regularly and overall survival of patients before treatment were analyzed.The ORR of the good-risk group was significantly higher than that of the intermediate-risk group (75.6% vs 57.7%, P = .044) and the poor-risk group (75.6% vs 48.2%, P = .007). The multivariate analysis results showed that age ≥ 65 years, International Staging System stage III, platelet count ≤ 100 × 109/L, lactate dehydrogenase (LDH) > 250 U/L, serum calcium > 2.75 mmol/L, no receipt of regular maintenance treatment, LMR < 3.6, suppressed u-Igs = 1, suppressed u-Igs ≥ 2, intermediate-risk group and poor-risk group were independent predictors of poor overall survival.In the bortezomib era, the LMR, u-Ig levels, and the immune score play an important role in the prognosis of NDMM patients. Among them, the immune score showed the strongest prognostic value, and it could be a beneficial supplement for the early identification of high-risk patients.

A randomized controlled study for Yuanhu Zhitong dropping pills in the treatment of knee osteoarthritis.

BACKGROUND: Knee osteoarthritis (KOA) is a common chronic disorder of knee and the leading cause of pain in the elderly with an overall prevalence of 50% in people over 60 years of age. This disease is an important factor affecting the quality of life of middle-aged and elderly people, and its main symptom is knee joint pain. Due to the pain, the knee joint activity function is limited, bringing great pain to patients, affecting their quality of life, effective prevention, and treatment of KOA is a modern medical problem. METHODS: The 60 patients who met the inclusion criteria were randomly divided into the treatment group and the control group. In this study, single center, randomized control and equivalent clinical trial were used for treatment. The treatment group received Yuanhu Zhitong dropping pills within 4 weeks, and the control group received diclofenac sodium sustained-release capsule treatment within 4 weeks. The main measures were visual analogue scale (VAS), WOMAC osteoarthritis index score and gastrointestinal symptoms rating scale (GSRS).Secondary measures included biochemical markers and adverse reactions during treatment. RESULT: The results of this trial will be published on the website of China Clinical Trial Registration Center (http://www.chictr.org.cn/searchprojen.aspx) and in peer-reviewed journals or academic conferences. CONCLUSIONS: This study is to assess the efficacy and safety of Yuanhu Zhitong dropping pills for knee osteoarthritis (KOA). REGISTRATION: PROSPERO (registration number ChiCTR1900024712).

Oral administration of ampelopsin protects against acute brain injury in rats following focal cerebral ischemia.

Ampelopsin (AMP) is isolated from the Chinese medicinal herb Ampelopsis grossedentata (Hand-Mazz) and has been associated with numerous biological and pharmacological activities. However, it is not clear whether AMP has a direct protective effect on cerebral ischemia reperfusion injury. Therefore, the present study investigated its role in acute brain injury following focal cerebral ischemia in rats. The current study induced transient focal cerebral ischemia by performing middle cerebral artery occlusion (MCAO) for 60 min, followed by 24 h of reperfusion. Rats were exposed to 40, 80 and 160 mg/kg AMP by oral administration 30 min prior to MCAO and the cysteinyl leukotriene receptor 1-antagonist, pranlukast (0.1 mg/kg, i.p.) was used as a positive control. Neurological deficit scores were observed and an inclined board test was used to assess behavioral dysfunction. The coronal slices were stained with 3,5-triphenyltetrazolium chloride to determine the infarct volume and brain edema. Neuronal morphology was assessed in brain sections stained with cresyl violet and degenerating neurons were identified using Fluoro-Jade B staining. Blood-brain barrier permeability was determined with immunoglobulin (Ig)G immunohistochemistry. Interleukin (IL)-1ß, tumor necrosis factor-α (TNF-α) in serum and cerebrospinal fluid were measured using ELISA kits. AMP at 80 and 160 mg/kg attenuated neurological deficits, reduced infarct volume, brain edema, IgG exudation and neuron degeneration and loss. Similar to pranlukast, AMP also inhibited the MCAO-induced IL-1ß and TNF-α release. Thus, AMP has a neuroprotective effect on acute brain injury following focal cerebral ischemia in rats at an effective oral dose of 80-160 mg/kg. The results of the current study indicate a therapeutic role for AMP in the treatment of ischemic stroke.
