OBJECTIVES: To explore the therapeutic mechanism of Arctium lappa extract for treatment of Post-Viral Pneumonia Pulmonary Fibrosis (PPF). METHODS: The chemical constituents of Arctium lappa extracts were identified using UHPLC-Q-TOF-MS/MS. Mouse models of pulmonary fibrosis established by tracheal instillation of bleomycin were treated with Arctium lappa extract, and body weight changes were recorded and lung tissue pathology was examined using HE and Masson staining. Metabolomics analysis was used to identify the differential metabolites and the associated metabolic pathways in the treated mice. The common targets of viral pneumonia and pulmonary fibrosis were acquired from the publicly available databases, and the core targets and active constituents were screened using the protein-protein interaction (PPI) network, GO and KEGG enrichment analyses, and molecular docking, and a "gene-metabolite" regulatory network was constructed. The expressions of the core targets were detected in the lung tissues of the treated mice using Western blotting. RESULTS: Fifty-three chemical constituents were identified from Arctium lappa extract. In the mouse models of pulmonary fibrosis, treatment with Arctium lappa extract significantly improved weight loss and ameliorated lung inflammation and fibrosis. The differential metabolites in the treated mice were enriched in energy metabolism pathways involving citrate cycle, pentose phosphate pathway, glycolysis, tryptophan metabolism, glutamate metabolism and glutathione metabolism, which regulated the production of energy metabolism intermediates. Twenty-three key active compounds (mostly lignans and phenolic acids) and 82 core targets were screened, which were associated with the non-canonical Smad signaling pathways (including PI3K/AKT, HIF-1, MAPK, and Foxo) that participated in the regulation of energy metabolism. Arctium lappa extract also regulated the expressions of epithelial-mesenchymal transition (EMT)‑related proteins (fibronectin, vimentim, and Snail, etc.) and inhibited MAPK signaling pathway activation. CONCLUSIONS Preliminary findings suggest that Arctium lappa treats fibrosis by regulating metabolism to inhibit EMT and involves the modulation of non-canonical Smad signaling pathways, such as MAPK providing theoretical support for its clinical application and further research in treating PPF.

Objective To systematically review the clinical efficacy of paroxetine plus olanzapine versus paroxetine alone among depression complicated with sleep disorder patients in China.Methods PubMed,Embase,Cochrane Library,CINAHL,SinoMed,CNKI,VIP,WanFang Data databases,SUMsearch and Google search engine were electronically searched to collect randomized controlled trials(RCTs)of paroxetine plus olanzapine versus paroxetine in the treatment of depression complicated with sleep disorder Chinese patients from inception to April 3,2023.Two researchers independently screened the literature,extracted data and evaluated the risk of bias of the included studies,and the Meta-analysis was then performed by using RevMan 5.3 software.Results A total of 70 RCTs involving 5 683 patients were included.The results of Meta-analysis showed that:(1)the total effective rate in experimental group was significantly higher than that of the control group(OR=5.98,95％CI 4.51 to 7.94,P＜0.001);(2)Pittsburgh sleep quality index scores after treatment in the first month(MD=-2.81,95％CI-3.24 to-2.38,P＜0.001),in 2 months(MD=-2.41,95％CI-3.13 to-1.70,P＜0.001),in 3 months(MD=-2.80,95％CI-3.18 to-2.42,P＜0.001)and in 6 months(MD=-1.65,95％CI-1.83 to-1.48,P＜0.001)in experimental group were significantly lower than the control group;(3)Hamilton depression scale scores after treatment in the first month(MD=-5.79,95％CI-6.63 to-4.95,P＜0.001),in 2 months(MD=-4.33,95％CI-5.45 to-3.21,P＜0.001),in 3 months(MD=-3.76,95％CI-4.17 to-3.34,P＜0.001)and in 6 months(MD=-3.38,95％CI-3.60 to-3.15,P＜0.001)in experimental group were significantly lower than the control group;(4)Hamilton anxiety scale scores in experimental group were significantly lower than the control group(MD=-3.47,95％CI-3.78 to-3.16,P＜0.001).Conclusion Current evidence shows that,compared with the paroxetine alone in the treatment of depression complicated with sleep disorder patients in China,paroxetine plus olanzapine can effectively increase patients'total effective rate of clinical treatment,improve the sleep quality and depression symptoms in 1 month,2 months,3 months and 6 months after treatment,and also reduce patients'anxiety.Due to limited quality and quantity of the included studies,more high-quality studies are required to verify above conclusions.

Cancer anorexia/cachexia syndrome (cancer anorexia cachexia syndrome, CACS) is a common complication in advanced cancer patients, which is characterized by reduced feeding, sustained weight loss, general fatigue and weakness. CACS related symptoms make patients suffer from a series of adverse psychosocial effects, such as anxiety, pain and social isolation, thus bringing serious adverse effects on patients′ individuals, families and society. This paper reviewed the symptoms associated with CACS and their psychosocial effects, as well as the interventions related to adverse psychosocial effects, in order to provide theoretical reference for alleviating psychosocial distress and improving health-related quality of life of patients with CACS.

Objective:To translate the Health Literacy of Caregivers Scale-Cancer (HLCS-C) into Chinese and test its reliability and validity.Methods:The British translation model was used to translate and back translate the English version scale, and the Chinese version scale was initially verified and revised through expert consultation and pre-test. From June to September 2021, 242 caregivers of cervical cancer patients admitted to Shandong Cancer Hospital were selected by convenient sampling. The revised Chinese version of HLCS-C was used to investigate the caregivers for reliability and validity test. A total of 242 questionnaires were distributed and 226 valid questionnaires were recovered.Results:There were 44 items in the Chinese version of HLCS-C. The exploratory factor analysis showed that the scale included 8 dimensions, namely cancer information collection, cancer information mastery, social support, cancer related communication with patients, understanding of patients' needs and preferences, health and healthcare service use, health information processing, and active participation with medical and nursing staff, with a cumulative variance contribution rate of 73.448%. The scale-level content validity index ( S- CVI) was 0.981, and the item-level content validity index ( I- CVI) was 0.833 to 1.000. The total Cronbach's α coefficient of the scale was 0.946, and Cronbach's α coefficient of each dimension was 0.700 to 0.945. The total half-reliability coefficient of the scale was 0.791, and the half-reliability coefficient of each dimension was 0.635 to 0.867. Conclusions:The Chinese version of HLCS-C has good reliability and validity, and can be used as an assessment tool for the health literacy of cervical cancer caregivers.

Autism spectrum disorder (ASD), a representative disease of children's neurodevelopmental disorders, brings huge pressure and financial burden to families and society. It is of great significance to explore its etiology and pathogenesis. Therefore, we established an ASD Cohort based on the existing China National Birth Cohort (CNBC), which applied parallel design to recruit and follow up families who achieved pregnancy after receiving assisted reproductive technologies (ART) and families with spontaneous conception. The main aims of this study are to compare the incidence of ASD among children born after ART with those born under spontaneous pregnancy, and to evaluate the impact of ART on the neurobehavioral development of offspring. Additionally, with a variety of clinical and behavioral related information collected during pregnancy and at early life of offspring, we are able to investigate the risk factors associated with ASD comprehensively. This article briefly introduces the objectives, contents, preliminary progress, strength and limitations, as well as further prospects of the ASD cohort study, mainly focusing on the overall design and current progress.

Objective:To investigate and analyze the epidemiological and clinical characteristics of 46 patients with corona virus disease 2019 (COVID-19) in Beijing City.Methods:A retrospective study was conducted to analyze the data of 46 patients with COVID-19 in Beijing from 20th January 2020 to 8th February 2020 at the Fifth Medical Center of the PLA General Hospital in Beijing City. Twelve, 23 and 11 patients were assigned to the mild group, common group and severe group, respectively. The epidemiological history, clinical characteristics, laboratory tests and imaging inspections were analyzed. Statistical analysis used Fisher exact test. If P<0.05, post- hoc test was used for pairwise comparison, and the statistics were corrected by Bonferroni test. Results:Among the 46 patients included in this study, 27 were male and 19 were female. The age range was between 3-79 years old, and the age was (41.8±16.3) years old. The average incubation period was (4.85±3.00) days. A total of 26 cases (56.5%) were clustered patients, and 26 cases had a history of staying in Wuhan, 10 cases had contact with Wuhan personnel. Fever (39 cases, 84.8%), cough (27 cases, 58.7%), and fatigue (25 cases, 54.3%) were the main clinical symptoms for these patients. The decrease in white blood cell counts occurred in 12 patients, four had the decrease in T lymphocyte percentage, 17 had the decrease in CD4 + T lymphocyte counts, seven had the decrease in CD8 + T lymphocyte counts, 21 had the increase level of C reactive protein (45.7%), and interleukin-6 (IL-6) level increased in 32 cases (69.6%), erythrocyte sedimentation rate (ESR) increased in 23 cases (50.0%), serum ferritin level increased in 26 cases (56.5%), and blood lactic acid level increased in nine cases. There were statistically significant differences in the proportion of cases with decreased absolute value of CD8 + T lymphocytes and T lymphocytes counts among the mild, common and severe groups (all P<0.05). Comparing the proportion of cases in the three groups with elevated C reactive protein, IL-6, ESR, serum ferritin and blood lactic acid levels, the differences were statistically significant (all P<0.05). The proportion of cases with elevated C reactive protein levels in severe group was higher than those in mild and common groups. The proportion of cases with elevated IL-6, ESR, and serum ferritin levels in severe and common group were higher than those in mild group. The proportion of cases with elevated blood lactic acid levels in severe group was higher than those in mild group. The differences between the above groups were statistically significant (all adjusted P<0.017). Analysis of chest X-rays results showed that 34 patients (73.9%) had inflammation in the lungs. Conclusions:The epidemiological characteristics of patients with COVID-19 in Beijing City are mainly imported cases and clustered cases. The clinical manifestations are mainly fever, fatigue and cough. C reactive protein, IL-6, ESR, serum ferritin and blood lactic acid levels are higher in severe patients.

Objective: To investigate the clinic-pathological features and prognostic risk factors of IgA nephropathy (IgAN) with hypertension (HTN). Methods: Primary IgAN patients diagnosed with biopsy from January 2016 to December 2017 were recruited. Patients were divided into IgAN with normal blood pressure (IgAN-NTN) group and IgAN with hypertension (IgAN-HTN) group based on the pressure value when performing the kidney biopsy. The clinical and pathological data were collected and compared between the two groups. Kaplan-Meier method was conducted for renal results, whereas the Cox regression model was exploited to analyze the prognostic factors in the progression of IgAN-HTN patients. Results: The total number of enrolled patients was 275 cases, 170 (61.82%) of which had normal pressure and 105 individuals (38.18%) resulted in hypertension. The IgAN-HTN group in terms of male proportion, age, systolic pressure, diastolic pressure, serum urea nitrogen, serum creatinine, serum uric acid, 24 h urinary protein, triacylglycerol, complement C4 and so on were higher than those in the IgAN-NTN group (all P<0.05). The incidence of gross hematuria and the level of estimated glomerular filtration rate (eGFR) were significantly lower than those in the NTN group (all P<0.001). For the aspect of light microscope pathological manifestations, IgAN-HTN group exhibited more severe histological lesions including glomerular sclerosis, renal tubular atrophy or renal interstitial fibrosis, interstitial vascular injury than IgAN-NTN group (all P<0.05). Immunofluorescence examination results showed that the deposition ratio of C1q in IgAN-HTN group was higher than that in IgAN-NTN group (P=0.015). By employing Kaplan-Meier method, the cumulative renal survival rate in the HTN group was much lower than that in the NTN group (Log-rank test: χ²=6.456, P=0.011). For the patients in IgAN-HTN group, the cumulative renal survival rate in the dyslipidemia group was much lower than that in the ortholiposis group (Log-rank test: χ²=5.093, P=0.024). There was no significant difference in the cumulative renal survival rate between the blood pressure control group and the unqualified group (Log-rank test: χ²=1.036, P=0.309). As a result of univariate and multivariable Cox regression analysis, total cholesterol, eGFR and 24 h urinary protein were risk factors for renal progression of IgAN patients with hypertension. Conclusions The clinical manifestations and renal pathological changes in patients with IgAN-HTN are more serious than those in IgAN-NTN patients, which result in worse prognosis. IgAN-HTN patients should be paid more attention to the management of serum lipid level during treatment and follow-up.

OBJECTIVE:To investigate the characteristics and general rule of ADR induced by Ginkgo leaf extract and dipyri-damole injection,and to provide reference for clinical rational drug use. METHODS:UsingGinkgo leaf extract and dipyridamole injectionADRas subject,the journal articles were retrieved from CJFD during Jan. 1st,2005-Jun. 28th,2016,and then ana-lyzed statistically in respects of gender,age,primary disease,allergic disease,drug use,occurrence time of ADR,organs/systems involved and clinical manifestations. RESULTS:A total of 14 valid articles had been collected,involving 727 patients in total. Meanwhile,female was more than male(57.63% vs. 42.37%)and most of them aged more than 50 years;primary diseases were mainly thromboembolic disease and coronary heart disease;most of ADR happened within 30 min after medication (268 cases, 36.86%). Organs/systems involved in ADR were mainly nervous system (254 cases,28.60%),followed by skin and its appen-dants(228 cases,25.68%),digestive system(187 cases,21.06%);severe ADR could cause anaphylactic shock. There were 18 cases of new severe ADR (2.48%);all ADR cases were recovered,and no death occurred. CONCLUSIONS:It is suggested to strictly control indications,differential diagnosis and treatment,rational drug use,close monitoring through the whole process, maintain a high level of awareness to ADR.

Objective To compare the changes in myocardial fibrosis degree and left ventricular function before versus after percutaneous coronary intervention (PCI) in elderly patients with coronary heart disease (CHD).Methods 121 elderly patients diagnosed as CHD with a single vessel by coronary angiography were enrolled.All patients were treated with PCI guided by thrombolysis in myocardial ischemia (TIMI) grade,symptoms and fractional flow reserve (FFR) comprehensively,and reviewed by coronary angiography after 12 months.The changes in serum concentration of procollagen type Ⅰ (PC I),procollagen type Ⅲ (PC Ⅲ),laminin (LN),hyaluronic acid (HA) and aldosterone (ALD) before versus 3,12 months after PCI were detected by enzyme-linked immunosorbent assay (ELISA).Left ventricular ejection fraction (LVEF),left ventricular enddiastolic diameter (LVEDD),plasma N-terminal pro-B-type brain natriuretic peptide (NT-proBNP) level and 6-minute walk test (6MWD) were assessed before and 3,12 months after PCI.The correlations were analyzed between FFR and serum procollagen type Ⅲ level,between serum PC Ⅲ level and plasma NT-proBNP level,and between serum ALD level and serum levels of PC Ⅰ,PC Ⅲ,LN,HA.Results All patients were treated with PCI successfully.At 12 months after PCI,stenosis with different degree were found in implanted stents or some large vessels in 6 cases by coronary angiography FFR=0.56-0.82).The serum levels of PC Ⅰ,PC Ⅲ,LN,HA,ALD,LVEDD and the plasma levels of NT-pro BNP were lower at 3 months after PCI than at preoperative follow-up (all P＜0.05),but LVEF was higher at 3 months after PCI than at preoperative fellow-up (P＜0.05),and the change trends in above observations were more significantly at 12 months after PCI.Linear correlation analysis showed that there was negative correlation between FFR and PC Ⅲ (r=-0.67,P＜0.01).There were positive correlations between PC Ⅲ and NT-proBNP,between ALD and PCⅠ,PC Ⅲ,LN,HA respectively (r=0.67,0.52,0.55,0.46,0.51,all P＜0.01).Conclusions PCI comprehensively guided by TIMI grade,symptoms and FFR can reduce myocardial fibrosis,improve cardiac function and quality of life in elderly patients with single coronary heart disease.
