Psoriasis is a common chronic inflammatory systemic disease in dermatology. Its high prevalence， recurrence rate， and numerous comorbidities impose a significant physical and mental burden on patients. With the continuous advancement of modern medicine， the emergence of biological agents has improved clinical efficacy， making it possible to overcome psoriasis， in addition to classical treatments. However， in clinical practice， adverse reactions， drug resistance， recurrence rates， and immune drift cannot be ignored. Traditional Chinese medicine （TCM） has a history of thousands of years in treating psoriasis， demonstrating good efficacy， high safety， and a low recurrence rate， but a standardized management system is lacking. Therefore， the 25^th Clinical Diseases Responding Specially to TCM Treatment Series （Psoriasis） Youth Salon， hosted by the Chinese Association of Chinese Medicine and organized by the Youth Committee of the Chinese Association of Chinese Medicine， invited 29 experts and scholars from TCM， Western medicine， and interdisciplinary fields to actively discuss the "Advantages， Challenges， and Clinical Transformation of TCM and Western Medicine in the Diagnosis and Treatment of Psoriasis". The experts at the meeting concluded that the advantages of TCM in the treatment of psoriasis are as follows. Firstly， in the TCM-led treatment plan， TCM's understanding of psoriasis follows the principle of combining the differentiation of disease and syndrome. This approach distinguishes the basic contradiction from the current main contradiction and enables a clear grasp of the dynamic process of psoriasis development. Based on the system of syndrome differentiation and treatment， TCM intervention is applied to address the current main contradiction， and the optimal TCM treatment plan is formulated by combining internal and external treatments. Adhering to the principle of "what is visible outside must be addressed inside"， TCM can prevent and treat psoriasis comorbidities early by differentiating syndrome types. Secondly， in the integrated TCM and Western medicine treatment plan， the combination of both methods not only enhances efficacy but also reduces the adverse reactions of immunosuppressants and biological agents， lowering the recurrence rate. This conference provides a reference for the diagnosis and treatment of psoriasis using TCM and integrated TCM and Western medicine， opening up new ideas for clinical and basic research and guiding future research directions.

To implement the Opinions of the State Council of the Central Committee of the Communist Party of China on Promoting the Inheritance and Innovative Development of Traditional Chinese Medicine， delve into the diseases specifically responding to traditional Chinese medicine （TCM）， and serve the building of advantageous specialties， clinical talent cultivation， national research layout， and academic innovation， the Chinese Association of Chinese Medicine sponsored the salons in multiple fields to discuss the diseases specifically responding to TCM. On August 26， 2023， the 25^th salon on the diseases specifically responding to TCM was held in Shanghai. In view of the advantages of TCM and integrated traditional Chinese and Western medicine in the diagnosis and treatment of psoriasis， Chinese and western medicine experts and interdisciplinary researchers carried out extensive and in-depth discussions and formed specific suggestions and consensus on the diagnosis and treatment of psoriasis with TCM and integrated traditional Chinese and Western medicine. However， there was still a lack of detailed research path. Under the guidance of the Chinese Association of Chinese Medicine， this paper analyzes the problems in the diagnosis and treatment of psoriasis from the occurrence and development of psoriasis. According to the advantages and characteristics of TCM and integrated traditional Chinese and Western medicine in the diagnosis and treatment of psoriasis， this paper puts forward the main points of research layout for psoriasis from the three aspects of psoriasis diagnosis and treatment， comorbidity prevention， and chronic disease management as follows： ① optimization of the syndrome differentiation system for psoriasis， ② optimization of assessment indicators for psoriasis， ③ recurrence mechanisms of psoriasis， ④ construction and research of TCM prevention and treatment of psoriasis recurrence， ⑤ construction of the comorbidity spectrum and TCM theoretical system of psoriasis， ⑥ comorbidity mechanisms of psoriasis. Furthermore， this article proposed the research layout and directions， expected goals and values， and funding priorities. Therefore， on the basis of the series of salons about psoriasis as a disease specifically responding to TCM， this article puts forward the research paradigm of psoriasis， aiming to facilitate the high-quality development of TCM and provide reference for the national research layout， the research and development of new TCM preparations， the selection of research topics， and the formulation of guidelines and consensus.

Objective To investigate the clinical effect of respiratory trainer in the patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) undergoing non-invasive positive pressure ven-tilation.Methods A total of 85 patients with COPD undergoing non-invasive positive pressure ventilation ad-mitted and treated in the Affiliated Minda Hospital of Hubei Nationalities University during 2019-2023 were selected as the study subjects and divided into the experiment group and the control group through random number table method.The control group adopted the symptomatic and supportive treatment such as routine non-invasive positive pressure ventilation,anti-infection,preparation aspiration for spasmolysis and eliminating phlegm,while on the base of the control group,the experiment group adopted respiratory trainer (K5) for re-spiratory training each once in the morning and at night.The differences in the related indexes were compared between the two groups.Results The percentage of forced expiratory volume in the first second (FEV1％),forced expiratory volume in 1 second/forced lung capacity (FEV1/FVC),COPD assessment test (CAT) score,modified Medical Research Council Dyspnea Scale (mMRC) score,6-min walking distance (6MWD),SGRQ score,maximum inspiratory pressure (MIP),maximum expiratory pressure (MEP),partial pressure of carbon dioxide (PaCO2) and PaO2 on 3,7 d after treatment in both groups had statistically significant differ-ence compared with before treatment (P<0.05),and the improvement of the above indicators in the experi-ment group was more significant compared with the control group (P<0.05).Conclusion Respiratory train-er could improve the clinical effect and pulmonary ventilation function in the patients with acute exacerbation of COPD undergoing non-invasive positive pressure ventilation.

Objective To evaluate the Mandarin tracking of noise tolerance(TNT)test material and compare the differences between the average tolerable noise level(aTNL)value obtained from assessment and the program-estimated tolerable noise level(eTNL).Methods A total of 25 subjects with normal hearing and aural communica-tional ability were selected to undergo two of the mandarin TNT tests successively(respectively test 1,C1;test 2,C2),and 13 of them completed the third test(C3)under the same test condition as test 2 at least 1 week later.The stimulus for the three test conditions was presented with"speech 0°,continuous noise 180°".Results The aTNL of 25 participants for C1 and C2 was 83.42±3.09 dB SPL and 83.50±3.18 dB SPL,respectively.The eTNL of 25 participants for C1 and C2 were 84.08±3.53 dB SPL and 83.95±3.85 dB SPL,respectively.The aTNL and eT-NL for 13 subjects who participated in C3 was 83.16±2.13 dB SPL and 83.18±2.64 dB SPL,respectively.The intra-session(C1 vs C2)and inter-session(C2 vs C3)test-retest reliability were 2.36 dB and 2.75 dB,respectively.Pearson correlation analysis showed that intra-session(r=0.837,P＜0.001)and inter-session(r=0.867,P＜0.001)test-retest reliability was good.There was no statistical difference between aTNL and eTNL in the other TNT tests(P＞0.05 for both)except that aTNL and eTNL were statistically different in C1(P＜0.01),and more than 90％of the subjects could obtain eTNL within 1 minute.Conclusion The test-retest reliability of Mandarin tracking of noise tolerance test is good,with advantages of high reliability and efficiency.

This article has systematically sorted out and verified the name， origin， producing area， quality evaluation， harvesting and processing of Pruni Semen by consulting ancient materia medica， medical books， prescription books and modern literature， in order to provide a basis for the development of famous classical formulas containing Pruni Semen. The results showed that Pruni Semen， as a medicinal material， has been widely used in medical literature of past dynasties since it was collected in Shennong Bencaojing， and also included under the names such as Yuhe， Yuzi and Yuli， and aliases such as Jueli， Queli and Chexiali. The primordial plants mentioned in the past dynasties involve about 12 species of Rosaceae， but with Prunus humilis， P. japonica and P. glandulosa as mainstream varieties used in the past dynasties， while the 2020 edition of Chinese Pharmacopoeia stipulates that the basal plants are P. humilis， P. japonica and P. pedunculata. Most of the ancient records for the origin of Pruni Semen are found everywhere in high mountains， valleys and hills， modern literature records that its origin varies according to its base， for example， P. humilis and P. japonica are mainly produced in Hebei， eastern Inner Mongolia， Liaoning， Shandong and other regions of China， and P. pedunculata is mainly produced in Inner Mongolia. Modern literature summarizes its quality as faint yellow， full and fulfilling， neat and not broken， and non-oiling， and the small Pruni Semen is better than the big Pruni Semen. The ancient processing methods of Pruni Semen mainly include blanching and peeling， blanching and peeling followed by frying， and blanching and peeling followed by pounding， with the common feature of blanching and peeling. The successive editions of Chinese Pharmacopoeia stipulate that it should be pounded when used. Based on the results of the herbal textual research and the writing time of Bianzhenglu， and combined with the market survey of Pruni Semen， it is suggested that P. humilis or P. japonica should be used as the origin of Pruni Semen in Sanpiantang， and it is harvested when the fruits are ripe， the kernels are collected by removing the stones， and processed by blanching， peeling and pounding consulting the decoction method in the current edition of Chinese Pharmacopoeia.

Objective:To detect the abnormal changes of myocardial blood perfusion in patients with hypertrophic cardiomyopathy (HCM) by myocardial contrast echocardiography(MCE) combined with exercise stress test.Methods:Twenty-seven patients with clinically diagnozed of asymmetric HCM in Fuwai Central China Cardiovascular Hospital from May 2020 to April 2021 were selected as the HCM group, and 29 healthy subjects during the same period were selected as the control group. All patients underwent routine echocardiography, resting and exercise stress MCE. The myocardial perfusion parameters of each segment of interventricular septum in the 2 groups were quantitatively analyzed: the peak plateau intensity (A value), ascending slope of the curve(β value) and value of A×β. According to the end-diastolic myocardial thickness, the interventricular septum of the HCM group was divided into hypertrophic and non-hypertrophic segments, and the myocardial contrast parameters of the interventricular septum of the study group were compared with those of the control group. The myocardial blood flow reserve value of the two groups were calculated, and the correlation of myocardial blood flow reserve value with left ventricular mass index (LVMI) and left ventricular remodeling index (LVRI) were analyzed.Results:No matter at rest or under stress, the A value, β value and A×β value of ventricular septal hypertrophic and non-hypertrophic segments in the hypertrophic cardiomyopathy group were lower than those in the control group, and the differences were statistically significant (all P<0.05). Under stress, the A value, β value and A×β value of interventricular septal hypertrophic segments were lower than those in non-hypertrophic segments in the HCM group, and the differences were statistically significant (all P<0.05). The myocardial blood flow reserve in the HCM group was negatively correlated with LVMI and LVRI( r=-0.899, -0.676; all P<0.001). Conclusions:In patients with HCM under resting and exercise stress, microcirculation disorders were found in both hypertrophic and non-hypertrophic segments of the ventricular wall, and the myocardial blood flow reserve was negatively correlated with LVMI and LVRI.

Objective:To investigate the effectiveness and safety of nasojejunal tube placement in children by gastroscopic drafting method.Methods:We retrospectively analyzed the clinical data of children with nasojejunal tube placement from January 2016 to December 2021 in our hospital, and compared the operation time, successful rate and complications of nasojejunal tube placement in the gastroscopic wire drawing method retraction group(observation group)and the gastroscopic foreign body clamp placement method placement group(control group).Results:All of the 167 cases, 65 cases were in observation group and 102 cases in control group.There were no significant differences in sex and age between two groups( P>0.05). The operation time was(6.7±0.8)min in observation group and(8.2±1.3)min in control group, and the difference was statistically significant( t=8.312, P<0.001). The successful rate was 100% in observation group and 96% in control group.One child in control group complicated with the mucosal erosion and bleeding in the duodenal bulb, while the observation group with no erosion, bleeding, perforation, and other complications. Conclusion:The gastroscopic wire drawing method of nasojejunal tube placement has a shorter operation time, higher successful rates, and lower complication rates, which is significantly superior to the gastroscopic foreign body clamp placement method.

Objective:To summarize and analyze the clinical characteristics of different treatment in children with esophageal foreign bodies.Methods:This study collected 246 children with esophageal foreign bodies in our hospital from January 2016 to January 2020, which was divided into endoscopic group and operative group.The general and clinical data of children treated with different treatment were collected and statistical analyzed.Results:There were 222 children in endoscopic group and 24 children in operative group, respectively.The rate of surgery was 9.75%.There were no significant differences in gender and location of esophageal foreign bodies.However, the average age of operative group was(2.92±2.67) years, which significantly younger than that in endoscopic group(4.12±3.37)years( P=0.049). The residence time in operative group(median 29.10 h)was remarkable longer than that in operative group(median 11.80 h)( P<0.001). The proportion of sharpness(50.00%) and corrosive(45.83%) foreign bodies in operative group were more than those in endoscopic group[16.22% and 8.11%( P<0.001)]. Moreover, the occurrence rate of major complication in operative group was 83.33%, which was dramatically higher than that in endoscopic group(0.90%)( P<0.001). Conclusion:The younger and longer residence time of esophageal foreign bodies in children contribute to the rate of operative treatment.Additionally, the sharpness and corrosive foreign bodies increase the risk of surgery and serious complications.

Objective:To explore the clinical value of adenosine stress myocardial contrast echocardiography in detecting myocardial blood perfusion abnormalities in patients with type 2 diabetes mellitus.Methods:Twenty-six patients with type 2 diabetes mellitus clinically diagnosed from May 2019 to January 2020 in the endocrinology department of Fuwai Central China Cardiovascular Hospital and 28 healthy examinees with gender and age matched during the same period were enrolled. Routine echocardiography, rest and adenosine stress myocardial contrast echocardiography were performed, the plateau signal intensity(A value), curve rising slope(K value) and A×K value of the myocardial perfusion time-intensity curve were obtained by offline analysis. And general data such as age, gender, disease course, body mass index and glycated hemoglobin were collected, and results of the two groups were compared statistically.Results:In the rest state, the A value of the myocardial perfusion parameter in the diabetic group was not significantly different from that of the control group, both in whole and in segments ( P>0.05), while the K value and A×K value of the myocardial perfusion parameters in the diabetic group were significantly lower than those in the control group ( P<0.05). In the stress state, the A value, K value and A×K value of myocardial perfusion parameters in the diabetic group were significantly lower than those in the control group, both in whole and in segments ( P<0.05). The detection rate of myocardial perfusion abnormality in the stress state was significantly higher than that in the rest state, and the difference was statistically significant ( P<0.05). The myocardial blood flow reserve in the diabetic group was negatively correlated with the course of disease and the level of glycated hemoglobin ( r=-0.580, P=0.020; r=-0.481, P=0.013). Conclusions:Adenosine stress myocardial contrast echocardiography can be used for detection of left ventricular myocardial perfusion abnormalities in patients with type 2 diabetes mellitus, which has great clinical application value.

BACKGROUND: Derlin 3 (DERL3) is downregulated in colorectal cancer (CRC) samples. Its level is closely linked to lymphatic metastasis or distant metastasis rate in CRC patients. However, its biological behavior in lung adenocarcinoma were rarely reported. The aim of this study is to investigate the ectopic expression of DERL3 in lung adenocarcinoma tissues and its effect on the invasion and metastasis of lung adenocarcinoma A549 cell line to reveal the possible mechanism of invasion and metastasis of lung adenocarcinoma. METHODS: Lung adenocarcinoma microarray gene chip data included 3 cases of lymph node metastasis and 3 cases of lung adenocarcinoma tissue without lymph node metastasis. The GEDS and Kaplan-Meier plot queries the survival curve and expression level of DERL3. Western blot was used to detect the expression of DERL3 in lung adenocarcinoma cells. The efficiency of knockdown DERL3 gene was detected by Western blot assay. Transwell detected the number of cells passing through the basement membrane of the transwell. EDU assay detected cell proliferation ability. Western blot detected the expression of epithelial-mesenchymal transition related proteins E-cadherin and Vimentin. RESULTS: The microarray gene chip results showed that compared with lung adenocarcinoma tissues without lymph node metastasis, 1,314 mRNAs in lung adenocarcinoma tissues with lymph node metastasis were up-regulated, 400 mRNAs were down (P<0.05). The expression of DERL3 increased in lung adenocarcinoma (P<0.05). The results of survival curve showed that the lung cancer patients with high expression of DERL3 with poor prognosis (P<0.05). Western blot results indicated that plasmid transfection was successful. Knockdown of DERL3 suppressed the ability of proliferation, invasion and migration in A549 cells (P<0.05). After knockdown of DERL3, the expression level of Vimentin was decreased, while E-cadherin expression increased (P<0.05). CONCLUSIONS Knockdown of DERL3 inhibited the proliferation, invasion and metastasis of A549 cells.
