Post-stroke depression is a common complication after a stroke. Based on the theory of ＂deficiency of heart qi leading to sadness＂recorded in Huangdi Neijing, our team proposes that deficiency of heart qi is the basic pathogenesis of post-stroke depression, with sadness being its main manifestation. Therefore, we advocate treating post-stroke depression from the perspective of the heart, and clinically, it can be divided into four stages: heart-liver stage, heart-lung stage, heart-spleen stage, and heart-kidney stage. Treating post-stroke depression with the principle of regulating qi and nourishing the heart, patients in the heart-liver and heart-lung stages are mainly middle-aged and young adults, with a pathological nature of qi stagnation and mild deficiency of heart qi, and therefore, the method of promoting the flow of meridians and regulating qi should be adopted. In contrast, patients in the heart-spleen and heart-kidney stages are mainly middle-aged and elderly, with a pathological nature of qi deficiency and severe deficiency of heart qi, and therefore, nourishment and tonification should be prioritized. In response to the above four stages, our team has achieved good clinical efficacy by administering Xiaoyao Powder, Baihe Dihuang Decoction, Ganmai Dazao Decoction and Jingui Shenqi Pill respectively. This study discusses the approach to treating post-stroke depression from the perspective of a "deficiency of heart qi leading to sadness" by examining three aspects: the theoretical basis of Chinese and Western medicine to treat post-stroke depression from the heart, the basic pathogenesis and staging of post-stroke depression, and the treatment principle of regulating qi and nourishing the heart. The study also briefly analyzes the clinical experience of the medications used for this condition to provide a reference for the treatment of post-stroke depression.

Background and objective Lung cancer is a common malignant tumor of respiratory system.Endo-bronchial ultrasound-guided transbronchial needle aspiration(EBUS-TBNA)is a valuable tool for the diagnosis and staging of lung cancer.EBUS-TBNA is predominantly performed under local anesthesia or conscious sedation.However,the diagnostic performance of EBUS-TBNA under general anesthesia and in conjunction with rapid on-site evaluation(ROSE)remains un-certain.This study aims to investigate the value of general anesthesia and ROSE in the diagnosis of lung cancer with EBUS-TB-NA.Methods A retrospective analysis was conducted on 164 patients treated in the Department of Respiratory and Critical Care Medicine of The Affiliated Hospital of Southwest Medical University from January 2018 to December 2022.All patients were preoperatively suspected of lung cancer and underwent EBUS-TBNA.Based on whether they received general anesthesia and ROSE,the patients were divided into three groups:local anesthesia group(LA group)(n=54),general anesthesia group(GA group)(n=67)and general anesthesia with ROSE group(GA-ROSE group)(n=43).The puncture characteristics and diagnostic differences were analyzed among the groups.Results The number of lymph node puncture needles in the LA group was higher than in GA-ROSE group(P<0.01).The overall diagnostic rates of EBUS-TBNA for the three groups were 87.04%,89.55%and 90.70%,respectively,with malignant tumor diagnostic rates of 88.24%,88.89%and 94.74%.No statistically significant differ-ences were observed among the three groups(P>0.05).There were no instances of severe complications or adverse anesthesia reactions in any of the groups.Conclusion Compared to the combination of local anesthesia with intravenous analgesia and sedation,the implementation of EBUS-TBNA under general anesthesia,with or without ROSE,achieves equally accurate re-sults,and general anesthesia combined with ROSE can reduce in the number of lymph node puncture needles.

Chaihu Guizhi Decoction is an excellent prescription of ZHANG Zhongjing;however,nowadays the application of Chaihu Guizhi Decoction is primarily derived from the text.The xiang thinking is the source of traditional Chinese medicine thinking.Understanding Chaihu Guizhi Decoction from the xiang thinking,it is easy to perceive the true meaning of ZHANG Zhongjing,and grasp the location of the disease and the patient's overall qi,so as to make better use of this formula.This article discusses the understanding of Chaihu Guizhi Decoction from five perspectives:firstly,it gives an overview of the xiang thinking,pointing out the source and essential value of the xiang thinking;secondly,it analyses the disease position and the patient's qi of Chaihu Guizhi Decoction under the perspective of the xiang thinking as a whole;thirdly,it discusses the disease position and the patient's qi of the original text of Chaihu Guizhi Decoction from the xiang thinking;fourthly,it discusses how to understand the principle of formula formation and the main and minor parts of Chaihu Guizhi Decoction by xiang thinking;finally,it analyses the primary medicines in Chaihu Guizhi Decoction by using xiang thinking based on the records of Shennong Bencao Jing.Based on these five points,we hope to reveal the traditional Chinese medicine thinking behind Chaihu Guizhi Decoction,and provide new ideas for the clinical application of Chaihu Guizhi Decoction.

Primary hepatic carcinoma, hepatic carcinoma for short, is a common gastrointestinal tumor with an insidious onset and rapid progression, and its incidence rate is increasing year by year, seriously threatening the life and health of our people. At present, there is still a lack of specific markers for early diagnosis and treatment of hepatic carcinoma, so the research on its biological characteristics and pathogenesis has become very urgent. Metabolic reprogramming is one of the main characteristics of tumor cells, and lipid metabolic reprogramming is involved in the occurrence and development of hepatic carcinoma. Therefore, the key metabolic enzymes and regulatory molecules in the process of lipid metabolism are considered as important targets for the diagnosis and treatment of hepatic carcinoma. This paper mainly focuses on the signaling pathways and regulatory molecules related to hepatocellular carcinoma lipid metabolism, as well as the related anti-hepatoma drugs, so as to provide new ideas for the prevention and treatment of hepatic carcinoma.

Objective:To observe the physiological effect of bi-level positive airway pressure (BiPAP) ventilation among stable chronic obstructive pulmonary disease (COPD) patients.Methods:This was a small sample size, exploratory, interventional study. A total of 10 outpatients with stable COPD were included from Department of Pulmonary and Critical Care Medicine of Zhujiang Hospital, Southern Medical University between January 2018 and December 2018. The BiPAP mode of noninvasive mechanical ventilation was adopted. The inspiratory positive airway pressure was gradually increased from 10 cmH 2O (1 cmH 2O=0.098 kPa) to 24 cmH 2O, and each time by 2 cmH 2O. The expiratory positive airway pressure remained unchanged at 4 cmH 2O. Baseline and test data were collected before and during the ventilation for comparison, including total respiratory cycle time (T tot), inspiratory time (T i), inspiratory time (T e), inspiratory tidal volume (V Ti); mouth pressure (P mo), esophageal pressure (P eso), transdiaphragmatic pressure (P di), esophageal pressure time product (PTP es), diaphragm pressure time product (PTP di), root mean square of electromyography of diaphragm (RMS), V e/RMS, inspiratory capacity (IC), the change in end-expiratory lung volume (ΔEELV) and dynamic PEEPi (PEEPi dyn). Results:All the 10 patients completed the trial. Compared to calm breathing, V Ti, V e, P mo, IC, ΔEELV score and V e/RMS increased significantly with increasing pressure levels (all P<0.05); T e only increased significantly at 20-22 cmH 2O pressure levels compared to calm breathing ( P<0.05). P di, PTP es, PTP di, RMS and RMS/RMS max decreased significantly with increasing levels (all P<0.05). PTP es and PTP di converged to 0 and no longer showed significant changes after the 18 cmH 2O pressure level. RMS and RMS/RMS max flattened out at pressure level greater than 16 cmH 2O. T i/T tot only significantly decreased at the 20 cmH 2O pressure level compared to calm breathing. PEEPi dyn showed a tendency to decrease and then increase with increasing pressure levels. Conclusion:BiPAP ventilation, at appropriate pressure levels, significantly relieves pulmonary ventilation disorders and reduces the load of respiratory muscle in patients with stable COPD.

Background: Brucella infection induces brucellosis, a zoonotic disease. The intracellular circulation process and virulence of Brucella mainly depend on its type IV secretion system (T4SS) expressing secretory effectors. Secreted protein BspJ is a nucleomodulin of Brucella that invades the host cell nucleus. BspJ mediates host energy synthesis and apoptosis through interaction with proteins. However, the mechanism of BspJ as it affects the intracellular survival of Brucella remains to be clarified. Objectives: To verify the functions of nucleomodulin BspJ in Brucella's intracellular infection cycles. Methods: Constructed Brucella abortus BspJ gene deletion strain (B. abortus ΔBspJ) and complement strain (B. abortus pBspJ) and studied their roles in the proliferation of Brucella both in vivo and in vitro. Results: BspJ gene deletion reduced the survival and intracellular proliferation of Brucellaat the replicating Brucella-containing vacuoles (rBCV) stage. Compared with the parent strain, the colonization ability of the bacteria in mice was significantly reduced, causing less inflammatory infiltration and pathological damage. We also found that the knockout of BspJ altered the secretion of cytokines (interleukin [IL]-6, IL-1β, IL-10, tumor necrosis factor-α, interferon-γ) in host cells and in mice to affect the intracellular survival of Brucella. Conclusions BspJ is extremely important for the circulatory proliferation of Brucella in the host, and it may be involved in a previously unknown mechanism of Brucella's intracellular survival.

To scientifically evaluate the intervention effect of Chinese medicine preventive administration(combined use of Huo-xiang Zhengqi Oral Liquid and Jinhao Jiere Granules) on community population in the case of coronavirus disease 2019(COVID-19), a large cohort, prospective, randomized, and parallel-controlled clinical study was conducted. Total 22 065 subjects were included and randomly divided into 2 groups. The non-intervention group was given health guidance only, while the traditional Chinese medicine(TCM) intervention group was given two coordinated TCM in addition to health guidance. The medical instructions were as follows. Huoxiang Zhengqi Oral Liquid: oral before meals, 10 mL/time, 2 times/day, a course of 5 days. Jinhao Jiere Granules: dissolve in boiling water and take after meals, 8 g/time, 2 times/day, a course of 5 days, followed up for 14 days, respectively. The study found that with the intake of medication, the incidence rate of TCM intervention group was basically maintained at a low and continuous stable level(0.01%-0.02%), while the non-intervention group showed an overall trend of continuous growth(0.02%-0.18%) from 3 to 14 days. No suspected or confirmed COVID-19 case occurred in either group. There were 2 cases of colds in the TCM intervention group and 26 cases in the non-intervention group. The incidence of colds in the TCM intervention group was significantly lower(P<0.05) than that in the non-intervention group. In the population of 16-60 years old, the incidence rate of non-intervention and intervention groups were 0.01% and 0.25%, respectively. The difference of colds incidence between the two groups was statistically significant(P<0.05). In the population older than 60 years old, they were 0.04% and 0.21%, respectively. The incidence of colds in the non-intervention group was higher than that in the intervention group, but not reaching statistical difference. The protection rate of TCM for the whole population was 91.8%, especially for the population of age 16-60(95.0%). It was suggested that TCM intervention(combined use of Huoxiang Zhengqi Oral Liquid and Jinhao Jiere Granules) could effectively protect community residents against respiratory diseases, such as colds, which was worthy of promotion in the community. In addition, in terms of safety, the incidence of adverse events and adverse reactions in the TCM intervention group was relatively low, which was basically consistent with the drug instructions.

Objective: To analyze non-alcoholic steatohepatitis (NASH)-related differentially expressed genes (DEGs) by bioinformatics methods to find key pathways and potential therapeutic targets for NASH. Methods: GSE61260 chip was downloaded from the public microarray database and liver biopsy samples from 24 NASH cases and 38 healthy controls were included. The Limma software package in R language was used to screen DEGs under the condition of difference multiple > 1.5 and adj. P < 0.05. The clusterProfiler software package was used for GO analysis and KEGG analysis. The STRING online database was used for protein-protein interaction analysis, and the L1000 and DrugBank databases were used for drug prediction. Results: Compared with healthy control group, 857 DEGs were screened out in NASH group including 167 up-regulated genes and 690 down-regulated genes. GO analysis showed that DEGs were mainly involved in inflammation and cholesterol metabolism. KEGG analysis showed that DEGs were mainly enriched in PPAR, non-alcoholic fatty liver disease, oxidative phosphorylation and other signaling pathways. Among them, eight genes of ACSL4, CYP7A1, FABP4, FABP5, lipoprotein lipase, ME1, OLR1 and PLIN1 were enriched in PPAR signaling pathway, and 165 interaction nodes were formed with 47 DEGs-encoded proteins. Lipoprotein lipase interacted with 21 DEGs, and its up-regulated expression had improved lipid metabolism, insulin resistance and anti-inflammatory effects. Four drugs (gemfibrozil, bezafibrate, omega-3 carboxylic acid and glycyrrhizic acid) were screened by L1000 and DrugBank to activate lipoprotein lipase. Presently, these four drugs are clinically used to treat hypertriglyceridemia or to improve inflammation. In this regard, we speculated that the pharmacological effects of these four drugs had improved NASH by activating lipoprotein lipase to promote liver lipid metabolism and alleviate inflammation. Conclusion PPAR signaling pathway is closely associated to the occurrence and development of NASH, and thereby lipoprotein lipase agonist is a new attempt to treat NASH.

Objective: To study the segment of liver according to the large amount of three-dimensional(3D) reconstructive images of normal human livers and the vascular system, and to recognize the basic functional liver unit based on the anatomic features of the intrahepatic portal veins. Methods: The enhanced CT primitive DICOM files of 1 260 normal human livers from different age groups who treated from October 2013 to February 2017 provided by 16 hospitals were analyzed using the computer-aided surgery system.The 3D liver and liver vascular system were reconstructed, and the digital liver 3D model was established.The vascular morphology, anatomical features, and anatomical distributions of intrahepatic portal veins were statistically analyzed. Results: The digital liver model obtained from the 3D reconstruction of CAS displayed clear intrahepatic portal vein vessels of level four.Perform a digital liver segments study based on the analysis of level four vascular distribution areas.As the less anatomical variation of left hepatic portal vein, the liver was classified into four types of liver segmentation mainly based on right hepatic portal vein.Type A was similar to Couinaud or Cho′s segmentation, containing 8 segments(537 cases, 42.62%). Type B contained 9 segments as there are three ramifications of right-anterior portal vein(464 cases, 36.82%). The main difference for Type C was the variation of right-posterior portal vein which was sector shape(102 cases, 8.10%). Type D contained the cases with special portal vein variations, which needs three-dimensional simulation to design individualized liver resection plan(157 cases, 12.46%). These results showed that there was no significant difference in liver segmental typing between genders(χ²=2.179, P=0.536) and did not reveal any significant difference in liver segmental typing among the different age groups(χ²=0.357, P=0.949). Conclusions The 3D digital liver model can demonstrate the true 3D anatomical structures, and its spatial vascular variations.The observation of anatomic features, distribution areas of intrahepatic portal veins and individualized liver segmentation achieved via digital medical 3D visualization technology is of great value for understand the complexity of liver anatomy and to guide the precise hepatectomy.
