Objective To investigate the effect of coupled plasma filtration adsorption (CPFA) on plasma cytokines:TNF-α,IL-1β,IL-6,cellular immunity,blood lactate acid concentration,heart rate,respiration rate,oxygenation index,hemodynamics,blood cells counts,and prognosis in patients with multiple organ dysfunction syndromes (MODS).Methods This was a prospective,randomized clinical trial in 45 patients diagnosed as MODS.Patients were randomly assigned to hemoperfution with resin adsorption (HP) + continuous venous-venous hemofiltration (CVVH) group,CPFA group and CVVH group.The general clinical data,APACHE Ⅱ score,number of failure organ and previous mentioned biomarkers were documented.Blood samples were collected before and after blood filtration with any one of these procedures.The plasma samples were isolated and stored with frozen at-60 ℃.Data were statistically analyzed with SPSS 13.0 version software.Results In CPFA group,plasma cytokines,TNF-α、IL-1β、IL-6,decreased markedly after plasma adsorption for two hours (P ＜ 0.01);and plasma concentrations of IL-6 were further descended after subsequent CVVH for 10 hours (P ＜ 0.05).In HP + CVVH group,plasma cytokines,TNF-α、IL-1β、IL-6,decreased markedly after HP (P ＜ 0.01),and plasma concentrations of IL-6 were further descended after subsequent CVVH for 10 hours (P ＜ 0.05).In CVVH group,plasma cytokines,TNF-α、IL-1β、IL-6,decreased after CVVH for 12 hours (P ＜ O.05).Blood lactate acid concentration,heart rate,respiration rate,oxygenation index,T-lymphocytes subgroups (CD3 +,CD4 +,CD8 +,CD4 +/CD8 + ratio),clinical symptoms were improved and dose of vasoactive agent was reduced in the patients of three groups without differences among them.The counts of red blood cells,white blood cells and platelets after CPFA and CVVH showed no significant changes.There was no significant difference in blood cell counts between CPFA and CVVH groups.After HP + CVVH,there was a trend of decrease in platelet count (P ＜ 0.05).Platelet counts were significanfly higher in patients treated with CPFA and CVVH group than those in patients treated with HP + CVVH group (P ＜ 0.05).There were 6 patients died in HP + CVVH group,6 patients died in CPFA group and 5 patients died in CVVH group within 28days.Conclusions The comparison of efficacy of blood filtration among 3 modalities of HP + CVVH,CPFA and CVVH showed CPFA had higher capacity of Inflammatory medium scavenging than CVVH,and had less damage effect on blood visible component,especially on platelet compared with HP + CVVH.CPFA was an effective and safety modality in the treatment of the patients with multiple organ dysfunction syndrome.

Grooming,as an evolutionarily conserved repetitive behavior,is common in various animals,including humans,and serves essential functions including,but not limited to,hygiene maintenance,thermoregulation,de-arousal,stress reduction,and social behaviors.In rodents,grooming involves a patterned and sequenced structure,known as the syntactic chain with four phases that comprise repeated stereotyped movements happening in a cephalocaudal progression style,beginning from the nose to the face,to the head,and finally ending with body licking.The context-dependent occurrence of grooming behavior indicates its adaptive significance.This review briefly summarizes the neural substrates responsible for rodent grooming behavior and explores its relevance in rodent models of neuropsychiatric disorders and neurodegenerative diseases with aberrant grooming phenotypes.We further emphasize the utility of rodent grooming as a reliable measure of repetitive behavior in neuropsychiatric models,holding promise for translational psychiatry.Herein,we mainly focus on rodent self-grooming.Allogrooming(grooming being applied on one animal by its conspecifics via licking or carefully nibbling)and heterogrooming(a form of grooming behavior directing towards another animal,which occurs in other contexts,such as maternal,sexual,aggressive,or social behaviors)are not covered due to space constraints.

Objective: Conebeam CT (CBCT) was used to measure the palatine between the maxillary first and second molars. The proximal and distal palatal widths of the maxillary first and second molar and the palatal mucosal thickness and bone tissue thickness when microscrew implant anchorage nail were implanted at different angles provided a reference for the clinical selection of microscrew implant placement. Methods: The image data of 90 adult patients were selected as the research object, and the jaw bone was reconstructed by scanning. In maxillary palatine, selection of distances at 12 mm, 14 mm, 16 mm, and 18 mm from the palatal apex of maxillary first molar between the maxillary first and second molar were used as measurement, measured the proximal and distal palatal widths of maxillary first and second molar and the palatal mucosal thickness and bone tissue thickness when microscrew implant anchorage nails were implanted at 30 °, 45 °, 60 °, and 90 °. SPSS 26.0 software was used for one-way ANOVA and LSD pair comparison. Results: The larger the angle of the microscrew implant anchorage nail was, the smaller the proximal and distal medial widths between the maxillary first and second molar, and the difference was statistically significant (P < 0.05). Compared with the 90° direction, the proximal and distal medial widths of the microscrew implant anchorage nail were larger in the 60° direction. The greater the angle of implantation, the smaller the mucosal thickness and the greater the bone tissue thickness, and the results showed a significant difference (P < 0.001). Compared with the direction of 30° and 45°, the mucosal thickness at the direction of 60° was smaller, and the bone tissue thickness was larger. The higher the position of the microscrew implant anchorage nail, the greater the width of the proximal and distal medial, and the difference was statistically significant (P < 0.05). Compared with the positions 12 and 14 mm from the palatal tip, the proximal and distal medial widths of the microscrew implant anchorage nail were larger. The higher the implant position was, the greater the mucosal thickness and the smaller the bone tissue thickness. The results showed a significant difference (P < 0.001). Compared with the position of 18 mm from the palatal tip of the maxillary first molar, the mucosal thickness was smaller and the bone tissue thickness was larger. Conclusion It is most appropriate to implant microscrew implant anchorage nail at least 10 mm in length in the direction of 60° at the palatal apex 16 mm from the maxillary first molar in palatine between the first and second molar.

In recent years， the incidence of pulmonary nodules has kept rising. To give full play to the advantages of traditional Chinese medicine （TCM） in the treatment of pulmonary nodules and identify the breakthrough points of integrating TCM with Western medicine， the China Association of Chinese Medicine organized medical experts in TCM and western medicine to carry out in-depth discussion regarding this disease. The discussion encompassed the modern medical advances， TCM theories of etiology and pathogenesis， the role and advantages of TCM in the whole course management of pulmonary nodules， contents and methods of research on pulmonary nodules， and science popularization work， aiming to provide a reference for clinical practice and scientific research. After discussion， the experts concluded that the occurrence of pulmonary nodules was rooted in the deficiency of the lung and spleen and triggered by phlegm dampness， blood stasis， and Qi stagnation. TCM can treat pulmonary nodules by controlling and reducing nodules， improving physical constitution， ameliorating multi-system nodular diseases， reducing anxiety and avoiding excessive diagnosis and treatment， and serving as an alternative for patients who are unwilling or unfit for surgical treatment. At present， the optimal diagnosis and treatment strategy for pulmonary nodules has not been formed， which needs to be further studied from multiple perspectives such as clinical epidemiology， biology， and evidence-based medicine. The primary task of current research is to find out the advantages， effective prescriptions， and target populations and determine the effective outcomes of TCM in the treatment of pulmonary nodules. At the same time， basic research should be carried out to explore the etiology and biological behaviors of pulmonary nodules. The expert consensus on the diagnosis and treatment of pulmonary nodules with integrated TCM and Western medicine needs to be continuously revised to guide clinicians to conduct standardized， scientific， and accurate effective diagnosis and treatment.
