Résumé
@# In recent years, the number of lung surgeries has increased year by year, and the number of patients with postoperative cough has also increased gradually. Chronic cough after lung surgery seriously affects patients' quality of life and surgical outcome, and has become one of the clinical problems that clinicians need to solve. However, there is currently no guideline or consensus for the treatment of chronic cough after lung surgery in China, and there is no standardized treatment method. Therefore, we searched databases such as PubMed, Web of Science, CNKI, and Wanfang databases ect. from 2000 to 2023 to collected relevant literatures and research data, and produced the first expert consensus on chronic cough after lung surgery in China by Delphi method. We gave 11 recommendations from five perspectives including timing of chronic cough treatment, risk factors (surgical method, lymph node dissection method, anesthesia method), prevention methods (preoperative, intraoperative, postoperative), and treatment methods (etiological treatment, cough suppressive drug treatment, traditional Chinese medicine treatment, and postoperative physical therapy). We hope that this consensus can improve the standardization and effectiveness of chronic cough treatment after lung surgery, provide reference for clinical doctors, and ultimately improve the quality of life of patients with chronic cough after lung surgery.

OBJECTIVE To analyze the compositional differences between Fructus Tritici Levis and Triticum aestivum, and to provide reference for identification and quality control of both. METHODS Twenty batches of Fructus Tritici Levis and three batches of T. aestivum were collected, and their fingerprints were acquired by high-performance liquid chromatography and the similarities were evaluated by the Evaluation System of Similarity of Chromatographic Fingerprints of Traditional Chinese Medicine (2012 version). Cluster analysis (CA), principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA) were performed to analyze the difference of Fructus Tritici Levis and T. aestivum from different regions, and the differential components were screened. The contents of the six identified components in Fructus Tritici Levis and T. aestivum were determined. RESULTS The similarities of the fingerprints of Fructus Tritici Levis ranged from 0.928 to 0.996, and the relative similarities of T. aestivum with Fructus Tritici Levis ranged from 0.761 to 0.773. A total of 19 common peaks were calibrated, and six components including linolenic acid, linoleic acid, 5-heptadecylresorcinol, 5-nonadodecylresorcinol, 5- heneicosylresorcinol, and 5-tricosylresorcinol were identified. The results of CA and PCA showed that Fructus Tritici Levis and T. aestivum could be clearly distinguished; the distribution of Fructus Tritici Levis from Anhui province was relatively concentrated. The results of OPLS-DA showed that linolenic acid, linoleic acid, and other six unknown compounds were the differential components between Fructus Tritici Levis and T. aestivum. The average contents of the six identified components in Fructus Tritici Levis were 0.100 9, 1.094 0, 0.005 1, 0.030 9, 0.098 2,and 0.024 8 mg/g, respectively; the contents of linolenic acid and linoleic acid in Fructus Tritici Levis were significantly higher than those in T. aestivum (P<0.05).CONCLUSIONS The established qualitative and quantitative methods are simple and reliable, and can be used for the identification and quality evaluation of Fructus Tritici Levis and T. aestivum. The identified differential components, such as linolenic acid and linoleic acid, can also provide clues for the differentiation and pharmacological study of Fructus Tritici Levis and T. aestivum.

Objective:To explore the correlation between the serum 25-(OH)D 3, adiponectin (APN), and chemerin levels of pregnant women with gestational diabetes mellitus (GDM) and insulin resistance. Methods:28 pregnant women with GDM were selected for the study group from May 2020 to December 2021, and 45 pregnant women with normal glucose tolerance were selected for the control group. 25-(OH)D 3, APN, chemerin, islet resistance index (HOMA-IR), fasting blood glucose, fasting insulin, and HbA1c were compared between the two groups. The correlation between 25-(OH)D 3, APN, chemerin, and GDM insulin resistance was analyzed. Results:Fasting blood glucose, fasting insulin, HOMA-IR, and chemerin in the GDM group were higher than those in the control group (all P<0.05), while 25-(OH)D 3 and APN were lower than those in the control group (all P<0.05). There was no statistical difference in HbA1c between the two groups. Logistic regression analysis showed that serum 25-(OH)D 3, APN, and chemerin were all related influencing factors of GDM (all P<0.05). Spearman's correlation analysis showed that serum 25-(OH)D 3 was negatively correlated with fasting blood glucose and HOMA-IR (all P<0.05), chemerin was positively correlated with fasting insulin and HOMA-IR (all P<0.05). ROC curve analysis showed that the AUC of 25-(OH)D 3 was 0.841 (95% CI: 0.746~0.967). AUC of APN was 0.678 (95% CI: 0.545~0.812). AUC of chemerin AUC was 0.360 (95% CI: 0.233~0.487). Conclusions:The levels of 25-(OH)D 3, APN, and chemerin have a certain correlation with the pathogenesis of GDM, which has a certain reference value for the prediction of GDM.

Objective To investigate the changes of coagulatory function in septic rats induced by cecal ligation and puncture(CLP). Methods Cecal ligation and puncture(CLP)were performed to induce sepsis in SD rats. Coagulation indexes were detected at 8,16 and 48 h after operation, and histopathological changes of the lung, kidney, liver and spleen were examined using HE staining. Results The 12-day survival rate of the CLP-induced septic rats was 30%,with an acute onset and high mortality. In the acute phase of disease development of the CLP rats, the activated partial thromboplastin time(APTT)was prolonged(P<0.05)at 8 h,the prothrombin time(PT)was prolonged at 16 h (P<0.05), the factor XII activity in the endogenous coagulation pathway and the factor VII activity in the extrinsic coagulation pathway showed a transient inhibition, the thrombin time(TT)was prolonged at 48 h(P<0.01), and the content of fibrinogen(FIB)was increased gradually from 16 h(P<0.001). Among the other important coagulation and anticoagulation indexes,the number of platelets(PLT)was decreased gradually from 8 h(P<0.01),while the number of vWF:Ag increased gradually from 8 h(P<0.001). The D-dimer amount gradually increased from 16 h(P<0.05),and the amount of PS:Ag significantly decreased until 48 h(P<0.001). However, there was no significant change in the antithrombin-III(AT-Ⅲ)content. The histopathological examination showed that there are different degrees of damages in the lung,kidney,liver and spleen tissues,but no obvious venous thrombosis and bleeding were found. Conclusions In the acute phase,there is coagulatory dysfunction in the septic rats,however,no histopathological changes such as venous thrombosis and bleeding were observed in the lung,kidney,liver and spleen tissues due to coagulatory dysfunction.

Objective Previous studies suggested that overerpression of Slit2 results in abnormal Alzheimer's disease-like behavior and cognition impairment in mice. The aim of this study is to investigate the relationship between overerpression of Slit2 and accumulation and clearance of amyloid-β in aging mice by comparing the differential expression of genes for accumulation and clearance of amyloid-β in aging Tg-Slit2 and Tg-2576 mice. Methods 14-month old male C57BL/6, Tg-Slit2 and Tg-2576 mice were used to detect the expression of Aβ1 - 40 and Aβ1 - 42 in brain by immunohistochemistry. Further, the total RNA in the brain of these mice were extracted, identified and inversely transcripted to cDNA, then the cDNA was detected by PCR array. The expression of genes in the brain of Tg-Slit2 and Tg-2576 mice were analyzed. Results Comparing with the Tg-2576 mice in the same age, accumulation of Aβ was not found in the brain of Tg-Slit2 and C57BL/6 mice. The result from PCR array analysis showed that comparing with the same aged C57BL/6 mice, there were 16 up-regulated genes and 8 down-regulated genes in the brain of Tg-Slit2 mice and 14 up-regulated genes and 17 down-regulated genes in the brain of Tg-Slit2 mice. The expression of amyloid beta precursor protein (APP) in the brain of the three group mice was not changed. The expression of presenilin 2 ( Psen2) related with Aβ production was significantly up-regulated in the Tg-2576 mice. In addition, the expression of low density lipoprotein receptor-related protein ( LRP) 6 and 9 were markedly decreased in the Tg-2576 mice. Notably, these genes were not changed in the brain of the aging Tg-Slit2 mice. Conclusions The accumulation of Aβ in the brain are not found in 14-month Tg-Slit2 mice, In addition, different from Tg-2576 mice, the significant changes of expression of Aβ-related genes is not found in the brain of Tg-Slit2 mice.
