ObjectiveTo investigate the effect of quercetin on acute gouty arthritis (GA) in rats by inhibiting the reactive oxygen species (ROS)/NOD-like receptor protein 3 (NLRP3)/interleukin-1β (IL-1β) signaling pathway. MethodsSixty SPF-grade male SD rats were randomized into normal, model, colchicine (0.3 mg·kg-1), and low-, medium-, and high-dose (25, 50, 100 mg·kg-1, respectively) quercetin groups (n=10). The rats in the dosing groups were administrated with the corresponding drugs (10 mL·kg-1) by gavage once a day for one week. An equal volume of normal saline was given by gavage to rats in normal and model groups. One hour after drug administration on day 5, an acute GA model was established in other groups except the control group via intra-articular injection of monosodium urate (MSU) suspension into the right posterior ankle joint cavity. The joint swelling and gait were scored at the time points of 6, 12, 24, 48 h after modeling. Histopathological alterations in the ankle joint tissue from each group were assessed by hematoxylin-eosin (HE) staining. Malondialdehyde (MDA), xanthine oxidase (XOD), and total superoxide dismutase (T-SOD) assay kits were used to assess the levels of MDA, XOD, and T-SOD in the serum. The levels of tumor interleukin-6 (IL-6), necrosis factor-α (TNF-α), and IL-1β in the rat serum, as well as ROS in the ankle joint tissue, were measured by enzyme-linked immunosorbent assay (ELISA). Western blot was performed to determine the protein levels of NLRP3, thioredoxin-interacting protein (TXNIP), apoptosis-associated speck-like protein containing a CARD domain (ASC), precursor cysteinyl aspartate-specific proteinase-1 (pro-Caspase-1), cleaved Caspase-1 (Caspase-1 p20), and IL-1β in the ankle joint tissue. Real-time PCR was employed to assess the mRNA levels of TXNIP, NLRP3, ASC, IL-1β, and TNF-α in the ankle joint tissue. ResultsCompared with the normal group, the model group exhibited decreased spontaneous activity, mental fatigue, increased ankle joint swelling and gait scores (P<0.01), aggravated synovial tissue edema and inflammatory cell infiltration (P<0.01), elevated levels of XOD, MDA, TNF-α, IL-1β, and IL-6 in the serum and ROS in the joint tissue (P<0.01), a declined level of T-SOD (P<0.01), up-regulated protein levels of NLRP3, TXNIP, ASC, pro-Caspase-1, Caspase-1 p20, and IL-1β in the ankle joint tissue (P<0.01), and up-regulated mRNA levels of NLRP3, TXNIP, ASC, IL-1β, and TNF-α in the ankle joint tissue (P<0.01). Compared with the model group, the medium- and high-dose quercetin groups showed improved general conditions, decreased gait scores (P<0.05, P<0.01), reduced joint swelling (P<0.01), alleviated synovial tissue edema and inflammatory cell infiltration (P<0.05, P<0.01), lowered levels of XOD, MDA, TNF-α, IL-1β, and IL-6 in the serum and ROS in the joint tissue (P<0.01), increased levels of T-SOD (P<0.01), down-regulated protein levels of TXNIP, NLRP3, ASC, pro-Caspase-1, Caspase-1 p20, and IL-1β in the ankle joint tissue (P<0.05, P<0.01), and down-regulated mRNA levels of TXNIP, NLRP3, ASC, IL-1β, and TNF-α in the ankle joint tissue (P<0.01). Low-dose quercetin also ameliorated some of the above parameters (P<0.05, P<0.01). ConclusionQuercetin exerts anti-GA effects by blocking the ROS/NLRP3/IL-1β signaling pathway, downregulating NLRP3 inflammasome activation, and inhibiting the production of pro-inflammatory cytokines including TNF-α, IL-1β, and IL-6.

OBJECTIVE:
This study aimed to explore the interplay between the life-course body mass index (BMI) trajectories and insulin resistance (IR) on incident diabetes.
METHODS:
This longitudinal cohort included 2,336 participants who had BMI repeatedly measured 3-8 times between 1989 and 2009, as well as glucose and insulin measured in 2009. BMI trajectories were identified using a latent class growth mixed model. The interplay between BMI trajectories and IR on diabetes was explored using the four-way effect decomposition method. Logistic regression and mediation models were used to estimate the interaction and mediation effects, respectively.
RESULTS:
Three distinct BMI trajectory groups were identified: low-stable ( n = 1,625), medium-increasing ( n = 613), and high-increasing ( n = 98). Both interaction and mediation effects of BMI trajectories and IR on incident diabetes were significant ( P < 0.05). The proportion of incident diabetes was higher in the IR-obesity than in the insulin-sensitivity (IS) obesity group (18.9% vs. 5.8%, P < 0.001). After adjusting for covariates, the odds ratios (95% confidence intervals) of the IR, IS-obesity, and IR-obesity groups vs. the normal group were 3.22 (2.05, 5.16), 2.05 (1.00, 3.97), and 7.98 (5.19, 12.62), respectively. IR mediated 10.7% of the total effect of BMI trajectories on incident diabetes ( P < 0.001).
CONCLUSION
We found strong interactions and weak mediation effects of IR on the relationship between life-course BMI trajectories and incident diabetes. IS-obesity is associated with a lower risk of incident diabetes than IR-obesity.

This article analyzes the current status of the researches on acupuncture-moxibustion for idiopathic facial palsy (Bell's palsy). Acupuncture-moxibustion is widely applied in treatment of Bell's palsy and the relevant researches are enriched. But the hierarchical discussion on the effectiveness is reported inadequately. Consequently, the necessity and advantages of acupuncture-moxibustion are hardly prominent. Besides, the safety of acupuncture-moxibustion in treatment is not fully explored. The common shortcomings are presented in professional study and statistical designs, and the quality of the evidences is not high. The recommendation strength of acupuncture-moxibustion is weak in international guidelines. The crucial questions are not deeply discussed, and there are lack of the recognized optimal protocol in clinical practical guidelines. It is suggested that the researches should improve the evaluation of the disease itself that may affect the prognosis of Bell's palsy, such as location, conditions and duration of illness, basic diseases and syndrome/pattern differentiation. The effect of acupuncture-moxibustion should be verified hierarchically, the questions on safety should be emphasized, the quality of study should be improved, the staging of treatment should be specified and the effect of acupuncture-moxibustion should be evaluated in multi-dimensions, and the elements of acupuncture-moxibustion should be optimized systematically in the aspects of timing, acupoint selection, needle devices, manipulation, intervention measures and regimen composition. So as to promote the research of acupuncture-moxibustion for Bell's palsy to a new process.

The paper introduces Professor FAN Gangqi's clinical experience in treatment of migraine. Regarding the syndrome/pattern differentiation of TCM, a four-approach framework is established, identifying the nature of illness, analyzing the syndrome/pattern and pathogenesis, determining the stage of illness, and identifying body constitution. In treatment, the principle of treatment is determined in line with syndrome/pattern differentiation, so as to ensure the therapeutic effect by means of "four dimensions". The acupuncture regimens are formulated in terms of the illness stages, "strong needling stimulation in acute stage for analgesia, and needle retaining in chronic stage for long-term effect". "Focusing on neuovascular pathway" is the effective approach to treatment of migraine with acupuncture and moxiubstion. The clinical holistic model by combining acupuncture with medication is advocated because that "the single acupuncture is weak in therapeutic effect, but with medication combined, the effect is enhanced". The different acupuncture techniques are provided comprehensively in treatment of migraine such as horizontal and row-like needling, collateral needling at Taiyang (EX-HN5), acupuncture at Sankong (Yuyao [EX-HN4], Sibai [ST2] and Jiachengjiang [Extra]), acupoint injection at Tianyou (TE16) and Renying (ST9), and acupoint embedding therapy at Fengchi (GB20).

Objective To achieve efficient compression of on-board radiotherapy projection images using dynamic video encoding algorithms.Methods The on-board radiotherapy imaging system primarily provides 2D X-ray projection images for patient positioning verification and 3D tomographic image reconstruction.Since multiple projection images acquired continuously exhibit strong spatiotemporal correlations,their similarities could be used to eliminate redundant information,thereby improving the image compression ratio.During image compression,the image sets obtained at different times were arranged into an image sequence which was input into a video encoder and output as a video file.During image decompression,the video file was input into a video decoder and output as an image sequence,and the images in the sequence were then assigned back to their original image sets.Three current dynamic video encoding algorithms(AVC,HEVC,and AV1)and the classic static image coding algorithm(JPEG 2000)were tested on a database of 2D projection images.The performance of various compression algorithms was evaluated using indicators such as compression ratio(CR),peak signal-to-noise ratio(PSNR),and structural similarity(SSIM).Moreover,visual comparison of projection images before and after compression was evaluated by clinical radiation oncologists.Results Dynamic video encoding algorithms achieved higher CR than the static image coding algorithm.The average CR of the 3 dynamic video encoding algorithms was as followed:CRAVC=11.50,CRHEVC=30.74,and CRAV1=27.10,while the average CR of the static image coding algorithm(JPEG 2000)was 5.28.For abdominal projection images,well-defined contours and textural details were preserved even when the CR reached 42.37.For head-neck projection images,although mild contour blurring emerged at a CR of 20.71,subsequent evaluation by clinical radiation oncologists confirmed that the reconstructed CBCT images still satisfied clinical requirements.Conclusion These dynamic video encoding algorithms effectively utilize the strong correlation information between multiple projection images,reduce the storage of redundant information,and greatly improve the image CR.
