The comparison between traditional Chinese medicine Jinzhen oral liquid (JZOL) and Western medicine in treating children with acute bronchitis (AB) showed encouraging outcomes. This trial evaluated the efficacy and safety of the JZOL for improving cough and expectoration in children with AB. 480 children were randomly assigned to take JZOL or ambroxol hydrochloride and clenbuterol hydrochloride oral solution for 7 days. The primary outcome was time-to-cough resolution. The median time-to-cough resolution in both groups was 5.0 days and the antitussive onset median time was only 1 day. This randomized controlled trial showed that JZOL was not inferior to cough suppressant and phlegm resolving western medicine in treating cough and sputum and could comprehensively treat respiratory and systemic discomfort symptoms. Combined with clinical trials, the mechanism of JZOL against AB was uncovered by network target analysis, it was found that the pathways in TRP channels like IL-1β/IL1R/TRPV1/TRPA1, NGF/TrkA/TRPV1/TRPA1, and PGE2/EP/PKA/TRPV1/TRPA1 might play important roles. Animal experiments further confirmed that inflammation and the immune regulatory effect of JZOL in the treatment of AB were of vital importance and TRP channels were the key mechanism of action.

BACKGROUND: Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE). METHODS: This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE. RESULTS: This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively. CONCLUSIONS Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.

SPSS software was used to do statistical analysis andχ22 test was applied. P<0 . 05 stands for statistically significant difference. Results Investigation results demonstrated that teaching competition of theoretical course was conducive to forming effective teaching atmosphere,achieving better teaching effect and improving teaching ability of teachers . A χ22 test was performed on the cognition of the cultivating of classroom management ability;results demonstrated that there were significant differ-ences between teachers with more than 10 years education age and those with less than 10 years education age(χ22=4.375,P=0.0365). Conclusions Teaching competition of theoretical course is an effective way to cultivate young teachers teaching ability. Teaching competition should be combined with training and feedback and evaluation should be more scientific and objective in order to improve young teachers' teaching ability.

OBJECTIVETo investigate the effects of short-term forest bathing on human health.

METHODSTwenty healthy male university students participated as subjects and were randomly divided into two groups of 10. One group was sent on a two-night trip to a broad-leaved evergreen forest, and the other was sent to a city area. Serum cytokine levels reflecting inflammatory and stress response, indicators reflecting oxidative stress, the distribution of leukocyte subsets, and plasma endothelin-1 (ET-1) concentrations were measured before and after the experiment to evaluate the positive health effects of forest environments. A profile of mood states (POMS) evaluation was used to assess changes in mood states.

RESULTSNo significant differences in the baseline values of the indicators were observed between the two groups before the experiment. Subjects exposed to the forest environment showed reduced oxidative stress and pro-inflammatory level, as evidenced by decreased malondialdehyde, interleukin-6, and tumor necrosis factor a levels compared with the urban group. Serum cortisol levels were also lower than in the urban group. Notably, the concentration of plasma ET-1 was much lower in subjects exposed to the forest environment. The POMS evaluation showed that after exposure to the forest environment, subjects had lower scores in the negative subscales, and the score for vigor was increased.

CONCLUSIONForest bathing is beneficial to human health, perhaps through preventive effects related to several pathological factors.

Objective Several studies have indicated that miR-15a,miR-15b and miR-16 may be the important regulators of apoptosis.Since attenuate apoptosis could protect myocardium and reduce infarction size,the present study was aimed to find out whether these miRNAs participate in regulating myocardial ischemia reperfusion (I/R) injury.Methods Apoptosis in mice hearts subjected to I/R was detected by TUNEL assay in vivo,while flow cytometry analysis followed by Annexin V/PI double stain in vitro was used to detect apoptosis in cultured cardiomyocytes which were subjected to hypoxia/reoxygenation (H/R).Taqman real-time quantitative PCR was used to confirm whether miR-15a/15b/16 were involved in the regulation of cardiac I/R and H/R.Results Compared to those of the controls,I/R or H/R induced apoptosis of cardiomyocytes was significantly iucreased both in vivo (24.4％ ± 9.4％ vs.2.2％ ± 1.9％,P ＜ 0.01,n =5) and in vitro (14.12％ ±0.92％ vs.2.22％ ± 0.08％).The expression of miR-15a and miR-15b,but not miR-16,was increased in the mice I/R model,and the results were consistent in the H/R model.Conclusions Our data indicate miR-15 and miR-15b are up-regulated in response to cardiac I/R injury,therefore,down-regulation of miR- 15a/b may be a promising strategy to reduce myocardial apoptosis induced by cardiac I/R injury.

Objective To investigate the clinical significance of NKp44+NK cells in the peripheral blood and synovial fluid of rheumatoid arthritis (RA) patients.Methods The proportions of NKp44+NK cells in the PB of 20 active and 15 remission patients with RA and 20 healthy individuals were detected using flow cytometry.The proportions of NKp44+NK cells in the SF of 10 active patients were detected.Multiple nonparametric test was used to compared the difference of NKp44+NK cells proportions.Clinical data including DAS28,anti-CCP antibody and RF were collected.The relationship between NKp44+NK cells and clinical data was analyzed by Spearman correlation analysis.Results The proportions of NKp44+NK cells in PB of active and remission patients and healthy individuals were (1.480±4.750)%,(0.540±0.590)%,(0.000±0.000)%respectively.The proportion of NKp44+NK cells in PB of active patients was significantly higher than that of remission patients and healthy individuals (x2=46.708,P=0.000).The proportion of NKp44+NK cells in the SF of ten active RA patients was significantly higher than matched PB.There was positive correlation between NKp44+NK cells proportion in PB and SF of active patients and DAS 28 and anti-CCP antibody level.There was no correlation between NKp44+NK cells proportion in PB,SF and RF.Conclusion There is a marked increase in the proportion of NKp44+NK cells in PB and SF of RA patients.Moreover,NKp44+NK cells are positively correlated with DAS28 and anti-CCP antibody,suggesting that NKp44+NK cells may be correlated with disease activity and severity.

OBJECTIVETo investigate the effect of NK-22 cells isolated from the synovial fluid (SF) of patients with rheumatoid arthritis (RA) on the proliferation of fibroblast-like synoviocytes and explore its possible mechanism.

METHODSThe proportions of NK-22 cells in the peripheral blood (PB) and the SF of 20 RA patients and 20 healthy individuals were determined by flow cytometry. NK-22 cells in the SF sorted by flow cytometry were cultured for two weeks followed by a 4-h stimulation with 20 ng/ml phorbol 12-myristate 13-acetate and 0.5 µ mol/L ionomycin. The culture supernatant of NK-22 cells was then harvested, in which the levels of IL-22 and TNF-α were measured by ELISA. The fibroblast-like synoviocytes were exposed to the culture supernatant for 24, 48, 72, and 96 h, and the changes in the cell proliferation were detected by MTT assay.

RESULTSRA patients showed a significantly greater proportion of NK-22 cells in both the SF and PB than the normal control subjects (P<0.05). NK-22 cells sorted by flow cytometry reached a purity exceeding 90%, and the levels of IL-22 and TNF-α in the culture supernatant of NK-22 cells cultured for two weeks were 941.16 pg/ml and 368.1 pg/ml, respectively. The culture supernatant of NK-22 cells caused a rapid proliferation of the fibroblast-like synoviocytes at 24, 48, 72, and 96 h after the exposure.

CONCLUSIONNK-22 cells in the SF of RA patients can promote the proliferation of fibroblast-like synoviocytes possibly due to the capacity of NK-22 cells to produce IL-22 and TNF-α.
