BACKGROUND:Traditional scoliosis orthosis has some disadvantages,such as complex manufacturing process,long processing cycle,poor fit and so on.Three-dimensional printed scoliosis orthosis has the advantages of high manufacturing precision and personalization. OBJECTIVE:To evaluate the efficacy of three-dimensional printed scoliosis orthosis for scoliosis based on multi-criteria decision model. METHODS:Clinical data of 72 patients with scoliosis admitted to Chen Xinghai Hospital of Integrated Traditional Chinese and Western Medicine from January 2019 to October 2022 were retrospectively collected and divided into two groups according to the treatment of orthosis.Study group(n=23)received three-dimensional printed scoliosis orthosis.Traditional group(n=49)received the traditional polypropylene spine brace treatment.The clinical efficacy and complications were compared between the two groups.A multi-criteria decision model for the treatment of scoliosis with three-dimensional printed scoliosis orthosis was established,and the stability of the benefit value,risk value and decision model of the two groups were evaluated. RESULTS AND CONCLUSION:(1)Compared with the traditional group,there were significant differences in the top vertebral offset distance,Cobb angle,top vertebral rotation,Functional Movement Screen score,visual analog scale score and total effective rate in the study group at 6 months after surgery(P<0.05).(2)Among the benefit indexes,Cobb angle had the greatest impact on the condition of patients,while the risk indexes had the greatest impact on dyspnea.(3)The benefit values of the study group and the traditional group for scoliosis were 79 and 64,and the risk values were 74 and 57,respectively.The combined benefit and risk values found that the benefit-risk value of the study group was 16 higher than that of the traditional group.(4)In the range of 0-100%relative risk weight,the benefit-risk value of the study group was always higher than that of the traditional group,which proved that the multi-criteria decision-making model had good stability.(5)It is indicated that three-dimensional printed scoliosis orthosis can better restore the physiological curvature of scoliosis and improve the efficiency of treatment.

ObjectiveTo investigate the efficacy and mechanism of saffron floral bio-residues（SFB） in the treatment of hyperuricemia（HUA） combined with gouty arthritis（GA） in a compound compatibility setting. MethodScreening candidate control Chinese medicines for compound and SFB based on network target distance calculation and data analysis. After adaptive feeding of 80 SD rats for 7 days， 10 rats were randomly selected as the blank group， while the remaining 70 rats were intraperitoneally injected with 3% potassium oxonate and orally administered with 1% adenine for 14 consecutive days. On the 13^th day， rats were injected with 2.5% sodium urate solution into the right ankle joint cavity to induce swelling of the joint capsule on the opposite side， inducing a HUA combined with GA model. At the same time， the modeling rats were randomly divided into 7 groups， including the model group， benzbromarone group（positive drug， 0.02 g·kg^-1）， Tongfengshu tablets group（9 g·kg^-1）， Tongfengshu granules group（9 g·kg^-1）， SFB granules group（3.6 g·kg^-1）， Plantaginis Semen granules group（3.6 g·kg^-1）， and new formula group（SFB replacing Plantaginis Semen in Tongfengshu granules， 9 g·kg^-1）， with 10 rats in each group. Each treatment group was orally administered with the corresponding drugs according to body weight， while the control and model groups were given equal volume of distilled water by gavage once a day for 14 consecutive days. After 14 days of synchronous administration and modeling， changes in gait， ankle joint swelling and mechanical pain threshold in rats were observed， and serum uric acid， creatinine， urea nitrogen and xanthine oxidase（XOD） were measured. Enzyme-linked immunosorbent assay（ELSIA） was used to detect the levels of tumor necrosis factor（TNF）-α， interleukin（IL）-1β and IL-6 in rat serum， hematoxylin-eosin（HE） staining was used to observe the pathological changes in the liver， kidney and ankle joints of rats， Western blot was used to detect the expression levels of uric acid transporter 1（URAT1）， glucose transporter 9 （GLUT9）， organic anion transporter 1（OAT1）， adenosine triphosphate（ATP） binding cassette transporter G2（ABCG2）， and liver XOD proteins. ResultThrough network pharmacology analysis， Plantaginis Semen was selected as a candidate control herb， and Tongfengshu tablets was used as a compound compatibility environment to explore the efficacy of SFB in reducing blood uric acid levels and treating GA. Animal experiments showed that compared with the blank group， the gait score and joint swelling degree of the model group were significantly increased， and the mechanical pain threshold was significantly decreased（P<0.01）. Compared with the model group， the gait score， joint swelling degree and mechanical pain threshold of rats in each medication group were improved to varying degrees. Biochemical indicators showed that compared with the blank group， the serum uric acid， creatinine， urea nitrogen and XOD levels of the model group were significantly increased（P<0.01）. Compared with the model group， the serum uric acid and XOD levels of rats in each treatment group were significantly decreased（P<0.01）. ELISA results showed that compared with the blank group， the levels of serum TNF-α， IL-1β and IL-6 in the model group were significantly increased（P<0.01）. Compared with the model group， the levels of TNF-α， IL-1β and IL-6 in the benzbromarone group， Tongfengshu tablets group， Tongfengshu granules group and new formula group were significantly reduced（P<0.05，P<0.01）. Western blot results showed that compared with the blank group， the expression levels of URAT1 and GLUT9 proteins in renal tissue and OXD protein in liver tissue of the model group were significantly increased， while the expression levels of renal OAT1 and ABCG2 were significantly decreased（P<0.01）. Compared with the model group， the expression levels of renal URAT1 and GLUT9 in the SFB granules group， Tongfengshu granules group and new formula group were significantly decreased， while the expression levels of renal OAT1 and ABCG2 were significantly increased， and the expression of XOD protein in liver tissue was significantly decreased（P<0.05， P<0.01）. Pathological analysis showed that focal infiltration of neutrophils， cell necrosis and nuclear fragmentation were observed in the liver tissue of the model group， sodium urate deposition crystals and tubular dilation appeared in renal tissue， synovial hyperplasia and inflammatory cell infiltration appeared in ankle joint. Compared with the model group， the abnormal degrees of liver， kidney and ankle joint tissue of rats in each treatment group were alleviated. ConclusionThe new formula of SFB replacing Plantaginis Semen has the same effect in the treatment of HUA combined with GA. This study proposes a new strategy to investigate the efficacy of new resources of Chinese medicine in a compound compatibility environment， which can provide a new demonstration for the research and development of new resources of Chinese medicine.

Objective To evaluate PICCO (pulse indicator continuous cardiac output) to predict fluid responsiveness in patients with acute lung injury secondary to septic shock.Methods We conducted a prospective study on 42 patients with acute lung injury secondary to septic shock.global end-diastolic volume index (GEDVI),pulse pressure variation (PPV),stroke volume variation (SVV),central vein pressure (CVP) and other haemodynamic data were recorded before and after fluid administration of 500 mL of 6％ hydroxyethyl starch.Responders were defined as patients with an increase in stroke volume index of at least 15％ after fluid loading.Performance of variables was analyzed using receiver operator characteristics analysis.Results GEDVI and PPV,but not SVV and CVP,were able to predict fluid responsiveness in patients with acute lung injury secondary to septic shock 1 hrs after admission to intensive care unit (ICU).The best area under the ROC curve (AUC) was found for GEDVI (AUC 0.802,P ＜0.01) and PPV (AUC 0.752,P ＜0.01) ; the optimal cut-off of GEDVI and PPV were 643.5 mL/m2 and 13.5％,respectively.At this cut point,the sensitivity was 90.9％,the specificity was 91.9％,however,only GEDVI was able to predict fluid responsiveness in patients with acute lung injury secondary to septic shock 6hrs afteradmission to ICU.The best area under the ROC curve (AUC) was found for GEDVI (AUC 0.788,P ＜ 0.01).the GEDVI ＜ 559 mL/m2 during loading were found to predict volume responsiveness with a sensitivity of 100％,specificity of 62.5％.Conclusions GEDVI and PPV predict fluid responsiveness in patients with acute lung injury secondary to septic shock in the early hours.

Hepatic myelopathy is one of special category changes of nervous system,which was secondary to the end-stage hepatic diseases and is a syndrome of myeleterosis.It usually occurred after portosystemic shunt surgery or collateral circulation of portosystemic vein.The prognosis of hepatic myelopathy is poor,and the progression of this disease is slow.Surgical approaches such as dissociation of colon and anastomosis of ileum and rectum aimed at reducing the absorption of toxic substance and thus to breakdown the blood ammonia and improve the symptoms of nervous system,but the effects are not satisfactory.The clinical data of 1 patient with hepatic myelopathy who received liver transplantation at the Second Affiliated Hospital of Dalian Medical University in April 2012 were retrospectively analyzed.The clinical symptoms and physical signs were improved,and muscle strength was effectively recovered in the patient.Liver transplantation might be an effective method for the treatment of hepatic myelopathy.

The current study aims to investigate the pharmacokinetic properties of Huangqin Tang on different oral doses. An LC-MS method for simultaneous determination of flavonoids and terpenoids in rat plasma was developed and validated. Plasma samples were treated with hydrochloric acid (containing 1% ascorbic acid), precipitated with acetonitrile, separated on a Zorbax SB-C18 column, detected by single quadruple mass spectrometry with an electrospray ionization interface, and quantified using selected ion monitoring mode. All pharmacokinetic parameters were processed by non-compartmental analysis using WinNonlin software. The results of specificity, linearity, intra-day and inter-day precisions, accuracy, and stability for LC-MS assay were suitable for the quantification of paeoniflorin, baicalin, wogonoside, baicalein, wogonin, oroxylin A, glycyrrhizic acid and glycyrrhetinic acid in rat plasma. The concentration-time profiles of baicalin, wogonoside, baicalein, wogonin, oroxylin A and glycyrrhizic acid showed double-peak phenomenon after Huangqin Tang was orally administered at 40 g x kg(-1) dose; all eight constituents in rat plasma showed good dose-exposure relationship within the dosage of 10-40 g x kg(-1); although plasma concentrations were different, the flavonoids with the same backbone showed the similar fate in the body with the corresponding dosage. In conclusion, the LC-MS assay was successfully applied for the pharmacokinetic study of multi-constituents of Huangqin Tang with different doses. Additionally, these constituents demonstrated good pharmacokinetic properties in the body.
