Objective: To determine the basal metabolic rate (BMR) of young adults aged between 20-29 years old in Changsha. Methods: We recruited volunteers to join in our research project from April to May, 2015. All recruited volunteers must meet the inclusion criteria: aged 20-29 years old, height between 164-180 centimeters in males and 154-167 centimeters in females, in good health condition, and with no habit of regular physical exercise in last year. Finally, 81 qualified volunteers were selected as research objects, including 43 males and 38 females. The BMR, resting lying metabolism rate and resting sitting metabolism rate of the subjects were detected, and the determined BMR was compared with the calculated results: from the adjusted Schofield equation. Results The BMR, resting lying metabolism rate and resting sitting metabolism rate among males were (166.10±22.09), (174.22±24.56), and (179.54±23.35) kJ·m^-2·h^-1, respectively, which were all higher than those among females were (137.70±20.04), (149.79±19.25), and (167.78±26.02) kJ·m^-2·h^-1, respectively, (P<0.001). The BMR of males and females calculated from the adjusted Schofield equation were (160.83±3.93), and (140.29±4.18) kJ·m^-2·h^-1, respectively, and there was no significantly statistical difference found between the determined BMR and the calculated results from Schofield equation (adjusted) classified by sex, all P values >0.05. Conclusion The BMR of young adults aged 20-29 years old in Changsha was in the national average level, and the adjusted Schofield equation displayed fine accuracy in predicting BMR of young adults aged 20-29 years old in Changsha.

OBJECTIVETo study the clinicopathologic features and differential diagnosis of small cell variant of peripheral T-cell lymphoma, not otherwise specified (PTCL, NOS).

METHODSThe clinicopathologic features of 5 cases of small cell variant of PTCL, NOS were retrospectively reviewed, with immunohistochemical study, T-cell receptor (TCR) gene rearrangement analysis and evaluation for Epstein-Barr virus (EBV) status.

RESULTSAll the 5 patients were males. The mean age was 52.6 years. The median duration before diagnosis was 1 month. Clinically, 3 patients presented in stage IV and 2 in stage III. Four of them had generalized lymphadenopathy and splenomegaly. Hepatomegaly and massive effusion were found in 1 and 2 cases, respectively. Marrow involvement was detected in 3 of the 4 patients with bone marrow biopsy performed and one of them also accompanied by lymphocytosis. Histologically, the involved lymph nodes showed partial or complete effacement of nodal architecture and replacement by a monomorphous population of small lymphoid cells. Scanty large lymphoid cells were also identified in 4 cases. Increase in number of blood vessels was noticed in two of them as well. Immunohistochemically, the lymphoma cells in all cases expressed two or more of the T-cell markers and CD43. The staining for CD20, TdT, CD56 and granzyme B was negative. CD99 expression was noted in 3 of the 4 cases. The Ki-67 index ranged from 5% to 15%. Clonal TCRgamma gene rearrangement was detected in the 4 cases studied and one of them also showed TCRbeta gene rearrangement. In-situ hybridization for EBV-encoded RNA was negative in the 4 cases studied. Follow up information was available in 3 of the 5 cases. All of the 3 patients died of the disease, with an average survival of 21.7 months.

CONCLUSIONSmall cell variant of PTCL, NOS represents a rare disease entity which often presents in advanced tumor stage and carries a poor prognosis.

Dried herb of Delphinium brunonianum Royle (Ranunculaceae) has long been used under the herbal name "Xiaguobei" (Delphinii Brunoniani Herba) in traditional Tibetan medicine and prescribed for the treatment of influenza, itchy skin rash and snake bites. In order to find a useful and convenient method for the identification of microscopic features, the technique of fluorescence microscopy was applied to authenticate "Xiaguobei" of Tibet. The transverse sections of stem and leaf, as well as the powder of "Xiaguobei" were observed to seek for typical microscopic features by normal light and fluorescence microscopy. A style-like, single-cell glandular hair containing yellow secretions on the leaf, young stem and sepal of "Xiaguobei" was found. Under the fluorescence microscope, the xylem and pericycle fiber group emitted significant fluorescence. This work indicated that fluorescence microscopy could be an useful additional method for the authentication work. Without the traditional dyeing methods, the main microscopic features could be easily found by fluorescence microscopy. The results provided reliable references for the authentication of "Xiaguobei".

Beclomethasone is an effective glucocorticoid, and beclomethasone-aptamer is a short single-stranded DNA with affinity and specificity to beclomethasone. The interaction between them is still unclear. The study of the interaction between aptamers and beclomethasone has a certain significance for the application of aptamers. In this study, high-resolution Fourier transform ion cyclotron resonance mass spectrometer (FT-MS) and molecular docking simulation technology were used to study the interaction between aptamer and beclomethasone. Firstly, under the optimized conditions of high-resolution mass spectrometry parameters, the complex of aptamer and beclomethasone was detected by the negative ion scanning mode with the electrospray ion source. Based on the results of high-resolution mass spectrometry, most of the compounds were -8-valent ions, and their dissociation constant K

The precise relationship between the degree of pain and the degree of inflammation in the individual remains debated. A quantitative analysis simultaneously applied to the immediate and prolonged painful consequences of inflammation has not yet been done. Thus, the correlations between edema, nociception and hypersensitivity following an inflammatory insult were assessed in rodents. To better understand the therapeutic value of modifying specific aspects of inflammation, the effects of an anti-inflammatory drug were compared to the results. Inbred strains of mice and outbred rats received an intraplantar injection of honeybee venom and the between-group and within-group correlations were calculated for spontaneous nociceptive measures, thermal and mechanical hypersensitivity, and edema and temperature. The effect of indomethacin on the pain and inflammation measures was examined. Edema correlated with spontaneous flinching, licking and lifting of the injected paw (P< or =0.003), and not with thermal or mechanical hypersensitivity. Indomethacin affected edema and spontaneous nociception dose-dependently, and affected hypersensitivity only at the highest dose tested (P< 0.05). These results suggest that edema may contribute only to immediate spontaneous nociceptive responses to an inflammatory insult, and not to the more clinically relevant prolonged hypersensitivity. This analysis represents a method for determining which inflammatory processes are the most promising therapeutic targets against the multiple painful consequences of inflammation.

Aim To explore the effect of cuminaldehyde in cumin fruit on gastric ulcer and the protective mechanism via establishing the gastric ulcer model of rats was by ethanol injury. Methods Thirty-six male R. norregicus were divided into six groups: control group, model group, omeprazole positive control group and cuminaldehyde low, medium and high dosage groups. After seven days of continuous intragastric administration, the acute gastric ulcer of R. norregicus was tested by absolute alcohol. Gastric ulcer area, inhibition rate, gastric tissue antioxidant activity, serum inflammatory factors and gastric mucosal protective factors were detected in different groups. Results The results showed that cuminaldehyde significantly reduced the area of gastric ulcer and increased the inhibition rate of gastric ulcer. The inhibition rate of cuminaldehyde at high dose group was up to 74.65%, the activities of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH) in gastric tissue significantly increased, and the contents of serum prolandin E

Objective To evaluate and analyze the panel composition and conflict of interest management of clinical practice guidelines of rehabilitation.Methods Clinical practice guidelines of rehabilitation were systematically retrieved from PubMed, EMBASE, China Biology Medicine disc, CNKI, Wanfang Data and Medlive database, the National Institute for Health and Care Excellence, National Guideline Clearinghouse, The Scottish Intercollegiate Guidelines Network, World Health Organization (WHO) and Guidelines International Network until January 11, 2020. Two researchers independently screened and cross-checked the literatures, and extracted the basic information of included guidelines, including the title, formulating institution, published journol, as well as the expert group, the number of expert group, the specific division of labor and their discipline, affiliation and the geographic location, the statement and management of conflict of interest, types of conflicts of interest, and whether to accept fund and the source of the fund.Results A total of 84 guidelines were finally included, 17 domestic ones and 67 foreign ones, in which, 52 (61.9%) reported the expert panel; 22 (26.2%) reported the number of expert panel groups, 21 (25.0%) indicated the specific division of work among the members of the expert panel, 74 (88.1%) reported the names of the members of the expert panel, 47 (56.0%) reported the subjects and specialties of the panelists, 70 (83.3%) reported the affiliation and location of panelists, 14 (16.7%) mentioned the management of conflicts of interest, and 25 (29.8%) reported if there were conflicts of interest. Only five of the 16 funded guidelines stated that there was no conflict of interest between the funding and the development of the guidelines. Among them, the reporting rate of expert panel was significantly higher in foreign countries than in China (χ2 = 9.542, P < 0.01), the reporting rate of name of expert panel members and specific division of labor were higher in foreign countries than in China ( χ2 > 4.155, P < 0.05), and the reporting rate of conflict of interest management was also higher in foreign countries than in China ( P < 0.05). There was no significant difference in whether there was a conflict of interest, whether it was funded and the type of funding at home and abroad ( P > 0.05). Conclusion In gerenal, clinical practice guidelines of rehabilitation published at home and abroad are necessary to be improved in the reporting quality of expert group formulation and division of labor, conflict of interest reporting and management. It is proposed that future guideline developers should follow the WHO Handbook for Guideline Development, assign roles of experts, strengthen the management and reporting of conflicts of interest, and standarderize the development process and reporting of the guidelines.

Objective To analyze the contents of the recommendations of stroke clinical rehabilitation guidelines in order to provide advice for the development and implementation of stroke rehabilitation guidelines.Methods PubMed, EMBASE, CNKI, China Biology Medicine disc, Wanfang databases and guideline-related websites were retrieved from the date of establishment to January 2020, to collect stroke clinical rehabilitation guidelines. The main content, recommendations based on evidence, the type of evidences, and the scope of evidence classification had been explored based on World Health Organization Handbook for Guideline Development-2nd Edition.Results A total of twelve guidelines were included in this study, one in Chinese and eleven in English. They were from the United States (3 guidelines), United Kingdom (3 guidelines), Canada (3 guidelines), Australia (2 guidelines) and China (1 guidelines), and published from September, 2005 to February, 2019. Three articles (25.0%) used the Appraisal of Guidelines for Research and Evaluation (AGREE) for quality evaluation, and two articles (16.7%) used Grading of Recommendations Assessment, Development and Evaluation (GRADE) as the grading system. The recommendations covered the areas such as: cognitive dysfunction (4 dimensions) with a recommendation of cognitive function assessment at most (7 guidelines, 66.7%), language and swallowing dysfunction (5 dimensions) with a recommendation of swallowing-related complications at most (10 guidelines, 83.3%), motor dysfunction (6 dimensions) with a recommendation of spasm treatment at most (10 guidelines, 83.3%), and psychological and behavioral dysfunction (4 dimensions) with a recommendation for assessment or monitoring at most (6 guidelines, 50.0%). There were many recommendations in these areas, but the types of evidence were different, and observational studies and/or randomized controlled trials accounted for most.Conclusion There are different types of evidence and levels of recommendation strength. It is proposed for future guideline developers in stroke rehabilitation to follow World Health Organization Handbook for Guideline Development-2nd Edition to improve the quality and the overall implementation of the rehabilitation guidelines, and to improve the quality and safety of rehabilitation.

Porcine epidemic diarrhea virus (PEDV) is a highly infectious pathogen that can cause severe diseases in pigs and result in enormous economic losses in the worldwide swine industry. Previous studies revealed that PEDV exhibits an obvious capacity for modulating interferon (IFN) signaling or expression. The newly discovered type III IFN, which plays a crucial role in antiviral immunity, has strong antiviral activity against PEDV proliferation in IPEC-J2 cells. In this study, we aimed to investigate the effect of PEDV nucleocapsid (N) protein on type III IFN-λ. We found that the N proteins of ten PEDV strains isolated between 2013 and 2017 from different local farms shared high nucleotide identities, while the N protein of the CV777 vaccine strain formed a monophyletic branch in the phylogenetic tree. The N protein of the epidemic strain could antagonize type III IFN, but not type I or type II IFN expression induced by polyinosinic-polycytidylic acid (poly(I:C)) in IPEC-J2 cells. Subsequently, we demonstrated that the inhibition of poly(I:C)-induced IFN-λ3 production by PEDV N protein was dependent on the blocking of nuclear factor-κB (NF-κB) nuclear translocation. These findings might help increase understanding of the pathogenesis of PEDV and its mechanisms for evading the host immune response.
