ABSTRACT
Secondary metabolites of medicinal plants are extremely important to human health because of their special pharmacological activities or efficacy. They are the main source of drugs, health care products, and cosmetics. As human beings continue to pursue health and longevity, the demand in the pharmaceutical market continues to grow. It becomes especially important to improve the production and quality of secondary metabolites of medicinal plants. Plant secondary metabolites are a kind of adaptation of plants to their environment and are the result of the interaction between plants and biotic and abiotic factors during the long-term evolution process. The production and accumulation of secondary metabolites in medicinal plants are mainly affected by plant genetic factors and environmental factors. Among them, light environment is extremely important for their synthesis. Therefore, light regulation has long been a research focus for many scholars in China and abroad. In this article, we the recent research progress on the effects of light regulation on the secondary metabolites of medicinal plants were reviewed, mainly focusing on the effects of light quality, light intensity and photoperiod, in order to provide theoretical basis and practical guidance for the efficient production of secondary metabolites with important pharmacological activities.
ABSTRACT
Objective To explore the impact of paricalcitol(Pal)on the oxidative stress-induced tight junction dam-age of mouse hepatocytes and its mechanism.Methods A model of cholestatic liver injury was created by routine bile duct ligation.The mice were randomly divided into control group(control),model group(BDL)and treatment group(BDL+Pal).HE staining microscopy was used to observe the morphological changes of liver tissues.The human hepa-toma cell line HepG2 was cultured and divided into blank group,model group(400 μmol/L H2O2)and treatment group(400 μmol/L H2O2+20 nmol/L Pal).Western blot was used to examine the level of tight junction protein 1(ZO-1),occludin,phosphorylated p65(p-p65),phosphorylated ERK(p-ERK)and phosphorylated myosin II regulated light chain(p-MLC)protein were checked in each group.Results Compared with the control group,the level of p-p65,p-ERK and p-MLC in the model group was significantly increased(P＜0.000 1 or P＜0.01 or P＜0.001).The protein expression of ZO-1 and occludin was significantly decreased(P＜0.01).HE staining mi-croscopy showed an increased hepatocyte necrosis and inflammatory cell infiltration.In contrast,the above levels in the treatment group showed an opposite trend relative to the model group.Conclusions Pal is able to alleviate the damage of hepatocyte tight junctions by inhibiting oxidative stress in cholestatic mice and HepG2 cells.Its mecha-nism is potentially related to the inhibition of reactive oxygen species and NF-κB/p65 and ERK signaling pathways.
ABSTRACT
The dissemination of culture requires carriers.The construction of hospital characteristic culture and hospital brand culture that highlights hospital characteristics needs to be recognized by medical staff and patients.A good hospital culture is one of the important factors to enhance hospital competitiveness,and can also enhance the hospital's reputation among the pub-lic.As a very common way of information circulation in China,self media and integrated media are rapidly developing and inno-vating in the field of healthcare.Hospitals should actively build their own"micro"cultural platforms.Using self media platforms to tell micro stories,popularize micro knowledge,shoot micro movies,publish micro books,hold micro forums,and micro mu-sic,to enrich patients'cultural lives and create an exclusive hospital culture.
ABSTRACT
OBJECTIVE To optimize the honey processing technology of Phellinus igniarius. METHODS The key factors of honey processing technology of P. igniarius （honey-water ratio， the mass ratio of honey-water to P. igniarius， the frying temperature and the frying time） were investigated by orthogonal test combined with analytic hierarchy process to determine the optimal technological parameters， using the internal quality （the contents of ergosterol， protocatechuic aldehyde and protocatechuic acid） and appearance traits as evaluation indexes. RESULTS The optimal process of honey-roasting P. igniarius was to take raw P. igniarius （1 cm3 square block）， add the appropriate amount of auxiliary materials （with 25 kg of refined honey and water for every 100 kg of P. igniarius）， mix well， moisten for 2 h until the auxiliary materials were completely absorbed； put it in a frying container， fry at the frying temperature of 130-140 ℃ for 5 min； take it out， put it in an oven at 50 ℃ for 2 h； take it out， and let it cool.

ABSTRACT
Accumulating studies have demonstrated that non-coding RNAs (ncRNAs), functioning as important regulators of transcription and translation, are involved in the establishment and maintenance of pregnancy, especially the maternal immune adaptation process. The endometrial stromal cells (ESCs), trophoblast cells, and decidua immune cells that reside at the maternal-fetal interface are thought to play significant roles in normal pregnancy and pregnancy-associated diseases. Here, we reviewed the up-to-date evidence on how microRNA, long non-coding RNA, and circular RNA regulate ESCs, trophoblast cells, and immune cells and discussed the potential applications of these ncRNAs as diagnostic and therapeutic markers in pregnancy complications.

Objective:To study the distribution and antibiotics resistance of the main pathogens of neonatal purulent meningitis in different regions of China.Methods:A retrospective descriptive clinical epidemiological study was conducted in children with neonatal purulent meningitis which admitted to 18 tertiary hospitals in different regions of China between January 2015 to December 2019. The test results of blood and cerebrospinal fluid, and drug sensitivity test results of the main pathogens were collected. The distributions of pathogenic bacteria in children with neonatal purulent meningitis in preterm and term infants, early and late onset infants, in Zhejiang Province and other regions outside Zhejiang Province, and in Wenzhou region and other regions of Zhejiang Province were analyzed. The chi-square test was used for statistical analysis.Results:A total of 210 neonatal purulent meningitis cases were collected. The common pathogens were Escherichia coli ( E. coli)(41.4%(87/210)) and Streptococcus agalactiae ( S. agalactiae)(27.1%(57/210)). The proportion of Gram-negative bacteria in preterm infants (77.6%(45/58)) with neonatal purulent meningitis was higher than that in term infants (47.4%(72/152)), and the difference was statistically significant ( χ2=15.54, P=0.001). There were no significant differences in the constituent ratios of E. coli (36.5%(31/85) vs 44.8%(56/125)) and S. agalactiae (24.7%(21/85) vs 28.8%(36/125)) between early onset and late onset cases (both P>0.05). The most common pathogen was E. coli in different regions, with 46.7%(64/137) in Zhejiang Province and 31.5%(23/73) in other regions outside Zhejiang Province. In Zhejiang Province, S. agalactiae was detected in 49 out of 137 cases (35.8%), which was significantly higher than other regions outside Zhejiang Province (11.0%(8/73)). The proportions of Klebsiella pneumoniae, and coagulase-negative Staphylococcus in other regions outside Zhejiang Province (17.8%(13/73) and 16.4%(12/73)) were both higher than those in Zhejiang Province (2.9%(4/137) and 5.1%(7/137)). The differences were all statistically significant ( χ2=14.82, 12.26 and 7.43, respectively, all P<0.05). The proportion of Gram-positive bacteria in Wenzhou City (60.8%(31/51)) was higher than that in other regions in Zhejiang Province (38.4%(33/86)), and the difference was statistically significant ( χ2=6.46, P=0.011). E. coli was sensitive to meropenem (0/45), and 74.4%(32/43) of them were resistant to ampicillin. E. coli had different degrees of resistance to other common cephalosporins, among which, cefotaxime had the highest resistance rate of 41.8%(23/55), followed by ceftriaxone (32.4%(23/71)). S. agalactiae was sensitive to penicillin, vancomycin and linezolid. Conclusions:The composition ratios of pathogenic bacteria of neonatal purulent meningitis are different in different regions of China. The most common pathogen is E. coli, which is sensitive to meropenem, while it has different degrees of resistance to other common cephalosporins, especially to cefotaxime.
ABSTRACT
Objective To explore the anti-tumor mechanism of saffron (Crocus sativus L.) by network pharmacology and reverse molecular docking techniques. Methods The main chemical components of saffron were obtained by searching published literature and TCMSP database. The potential targets of these components were predicted using PharmMapper server. The corresponding target genes were identified from UniProt database. The underlying anti-tumor targets of saffron were obtained by mapping the disease genes of cancer or tumor with GeneCards, OMIM and TTD databases. Cytoscape software was used to construct the action target network of saffron active components. The protein-protein interaction analysis was performed by String database, and the GO function and KEGG pathway enrichment analysis were performed by Metascape platform. Finally, molecular docking was performed to evaluate the binding of main components with their potential targets. Results A total of 9 active ingredients in saffron including quercetin, kaempferol, isorhamnetin, picrocrocin and crocin I, were identified, which might act on 37 key targets including AKT1, CCND1, MMP9, EGFR, TP53, involved in P53, TNF and other signaling pathways. Molecular docking indicated modest binding potency through hydrogen bonding, and hydrophobic interactions. Conclusion The anti-tumor effect of saffron was evaluated via the network of components-targets-pathways, which might provide a foundation for further research.
ABSTRACT
【Objective】 To analyze the blood dispatching of hospitals in Shijiazhuang area, in order to provide reference for blood dispatching policy of hospitals and ensure clinical blood supply. 【Methods】 The hospital blood dispatching data from 2018 to 2021 were queried through the blood center information management system (SHINOW9.5) and TMIS system, and the blood dispatching volume, frequency, variety and blood type distribution of hospitals at all levels were analyzed by SPSS statistical software. 【Results】 From 2018 to 2021, there were 1 196 times of blood dispatching in hospitals with a total volume of 4 648.5 U, showing a downward and then upward trend two years before and after the outbreak of COVID-19. As the main blood dispatching product, erythrocyte dispatching was 3 988 U, accounting for 85.79% of the total dispatching volume, with a dispatching rate of 2.99‰. The dispatching volume of red blood cells in secondary hospitals accounted for 86.13%.The dispatching rate of erythrocyte in secondary and tertiary hospitals was 1.03% and 0.06%, respectively, with significant difference(P<0.05). The dispatching rates of type A and AB red blood cells were 3.08‰ and 4.97‰, which were significantly different from those of type B and O red blood cells. 【Conclusion】 Blood dispatching has become an effective way to avoid blood waste and ensure emergency blood use in secondary and tertiary hospitals. In the actual operation, health administration department should strengthen supervision and hospitals should improve the blood dispatching process to ensure blood safety.
ABSTRACT
【Objective】 To develop a quick and accurate crossmatching test technology without the power equipment and additional reagents before blood transfusion, so as to improve the timeliness and safety of blood transfusion treatment in sudden situations as war or natural disasters. 【Methods】 The irregular antibodies quickly promote coagulants (QPC) were used as the reaction medium reagent. The 200 μL QPC were wrapped in the bursts bead and preset within different recess of the detection tubes. The bursts beads were squeezed with the reagent left in the well, then the blood samples were dropped in the main(recipient plasma: 200 μL, donor 3%—5% RBC: 100 μL) and secondary(donor plasma: 200 μL, recipient 3%—5% RBC: 100 μL)reaction grooves. The result interpretated by hand wrestling or 1 500 g centrifugation of 15 seconds. Meanwhile, the comparing experiments with the prior methods were implemented to evaluate the method’s reliability. 【Results】 The results of the bursting reagent, being stored at 37℃ for one week, were consistent with those of the freshly prepared cross-matching reagent, indicating that the bursting reagent was practical in the field and had good stability at normal temperature. No statistical difference between the sensitivity and the results of the microcolumn gel method was noticed by paired data t test (P>0.05). The parallel cross matching tests of 50 clinical samples were performed by microcolumn gel method and coagulant-bursting technique; the Kappa value was 0.973 2, and irregular antibodies were detected in 2 cases, with concordance rate at 100%, showing good consistency. 【Conclusion】 The improved method is simple and fast, and also safe and reliable for compatibility testing before blood transfusion, which is especially suitable for the field rescue of the wounded in wartime and sudden natural disasters, and is worthy of popularization.
ABSTRACT
As one of the important contents and links of doctor-patient communication, the quality of breaking bad news will affect the development of doctor-patient relationship. Bad news informed not only involves the feedback of clinical medical diagnosis results, but also involves special knowledge training and clinical experience accumulation, as well as ethical, legal, social custom and other factors. At present, it is still a difficult problem troubling physicians in the medical environment. From the different perspectives of doctors, patients and family members, this paper sorted out the domestic and international status of breaking bad news, revealed its internal dilemmas, and summarized the informing strategies to cope with these dilemmas, with a view to providing references for hospital managers and medical staff to earlier identify and properly inform, helping both doctors and patients to get rid of the dilemma of notification and improve the doctor-patient relationship.
ABSTRACT
β-amyloid protein (Aβ) is produced from β-amyloid precursor protein under the action of β-secretase and γ-secretase. Aβ accumulates and aggregates, forms oligomers and fibrils, and deposits in the brain, leading to functional neuronal death and cognitive impairment. β- amyloid protein induces inflammatory response, oxidative stress, free radical damage, calciumion disorder and so on, resulting in neuronal necrosis and apoptosis. Recent studies show that β-amyloid also plays an important role in hypoxia/ischemic brain injury. We review the mechanism of β-amyloid protein in hypoxic/ischemic brain injury.
ABSTRACT
【Objective】 To investigate the status quo and existing problems of quality control laboratory of blood stations in Hebei province, and to provide reference for the capacity building of quality control laboratory in the future. 【Methods】 The data of routine blood collection and supply, blood component preparation, blood sampling ratio/frequency, and sampling results among 12 blood stations in Hebei in 2020 were collected. The monitoring effect of blood component quality in Hebei province, combined with the indicator changes of main blood components, were analyzed. 【Results】 Blood component preparation from blood stations in Hebei are different. The requirements for the number and frequency of routine sampling in each apartment are not standardized, and retrospective analysis was not conducted basically. Although the frequency and sampling of blood component quality monitoring can meet the minimum requirements of the Quality Monitoring Guidelines of Whole Blood and Blood Components 2017 and Technical Operating Regulations of Blood Stations (2019 Edition), but does not match the actual collection and preparation units. The qualification rate and reliability are unstable due to the small sample size. Monthly quality inspection can result in judgment errors, which is not conducive to systematic analysis and continuous improvement of blood collection and supply process. 【Conclusion】 In the context of continuous enhancement of blood collection and supply standardization in Hebei Province, the blood quality monitoring mechanism based on intra-province consistency can be further studied to standardize intra-province homogenization of blood quality monitoring in multiple links including sampling rules, statistical analysis and data comparison calibers.
ABSTRACT
【Objective】 To evaluate the efficacy and safety of early interventions by traditional Chinese medicine oral liquid combined with plasma exchange in the treatment of pregnant women with high titer of ABO/Rh antibodies. 【Methods】 156 pregnant women with serum antibodies presenting high titer (ABO ≥512, Rh ≥ 64) in our hospital from May 2018 to April 2021 were randomly divided into traditional Chinese medicine group(group Ⅰ, n=68), traditional Chinese medicine combined with plasma exchange group(group Ⅱ, n=57) and control group (n=31). The control group were given VC, VEand oxygen uptake. Group Ⅰ were further given oral administration of traditional Chinese medicine liquid on the basis of treatment of the controls.

ABSTRACT
Objective:To investigate the expression of serum matrix metalloproteinase 3 (MMP-3) in patients with rheumatoid arthritis (RA) and analyze its correlation with bone erosion and disease activity.Methods:100 RA patients diagnosed in the First People's Hospital of Changde from July 2018 to December 2019 were selected as the RA group, and 35 healthy volunteers who came to the hospital for physical examination at the same time were selected as the control group. The clinical data of the patients were collected, and the serum MMP-3 levels of the patients and healthy volunteers were detected by enzyme-linked immunosorbent assay (ELISA). The serum MMP3 levels of RA patients with different disease activity, different imaging stages and different bone mineral density were compared, and the correlation with clinical indicators were analyzed.Results:⑴ RA patients were grouped according to the Disease Activity Score (DAS) 28. Serum MMP-3 levels in the highly active group (300.87±15.93)ng/ml and in the moderately active group (213.78±12.79)ng/ml were higher than those in the clinical remission group (82.87±8.19)ng/ml increased significantly. ⑵ The serum MMP3 level in the RA group (190.98±13.43)ng/ml was significantly higher than that in the healthy control group (69.97±10.63)ng/ml. ⑶ There were significant differences in serum MMP-3 levels among RA patients with different imaging stages ( P<0.05). The level of MMP-3 in stage Ⅲ (206.18±13.58)ng/ml and stage Ⅳ (301.72±13.43)ng/ml were significantly higher than those in stage Ⅰ (89.16±10.13)ng/ml. ⑷ RA patients were divided into normal group, osteopenia group, and osteoporosis group according to bone mineral density. The serum MMP-3 level in the osteopenia group (180.87±12.69)ng/ml and osteoporosis group (289.54±13.28)ng/ml were significantly higher than that in the normal group (121.05±8.45)ng/ml. ⑸ Serum MMP-3 levels were positively correlated with C-reaction (CRP), erythrocyte sedimentation rate (ESR), DSA 28, rheumatoid factor (RF), joint swelling index, joint tenderness index, and platelet count in the RA group ( P<0.05). Conclusions:The serum MMP-3 plays an important role in the progression of RA, and is closely related to RA disease activity and bone erosion. It is expected to become a serological indicator for predicting RA bone erosion and radiological progress.
ABSTRACT
Objective:To study the relationship between the expression of tumor markers and radical resection in patients with gastric cancer.Methods:The medical records of gastric cancer patients undergoing surgery in Department of Gastrointestinal Surgery, Puji District, Dongguan People′s Hospital Affiliated to Southern Medical University from June 2018 to December 2019 were retrospectively analyzed, and 136 patients were selected.Collected patient data, including general information, the expression levels of tumor markers carcinoembryonic antigen(CEA), carbohydrate antigen 19-9(CA19-9), carbohydrate antigen 72-4(CA72-4), and the surgical method used.The relationship between the expression of tumor markers and radical resection was observed.Results:There was no statistically significant difference in the radical resection rate of gastric cancer in different genders, ages, and locations of gastric cancer (all P>0.05). TNM classification (tumor node metastasis classification) stage III patients had a lower radical resection rate (63.3%(38/60)) than stage I (100%(27/27)) and II (100%(49/49)) (χ 2=58.166 and 81.208, P<0.001). The radical resection rate of CEA(+ ) patients (47.8%(44/92)) was lower than that of CEA(-) patients (90.9%(40/44))(χ 2=23.394, P<0.001). The radical resection rate of CA19-9(+ ) patients (47.7%(42/88)) was lower than that of CA19-9(-) patients(87.5%(42/48))(χ 2=20.804, P<0.001). The radical resection rate of CA72-4(+ ) patients (54.3%(51/94)) was lower than that of CA72-4(-) patients (78.6%(33/42)) (χ 2=7.268, P=0.007). The variables with P<0.1 in univariate analysis were included in the logistic regression model, including 4 variables including TNM stage, CEA, CA19-9, and CA72-4.The results showed that TNM staging ( OR=1.169, 95% CI=0.925-1.634, P=0.001), CEA ( OR=1.067, 95% CI=1.364-4.338, P=0.024), CA19-9( OR=3.012, 95% CI=1.679-6.317, P=0.007), and CA72-4 were independent risk factors for radical resection( OR=5.364, 95% CI=0.675-3.224, P=0.004). The number of positive expressions of tumor markers was negatively correlated with the radical resection rate ( r=-0.621, P<0.05). The expression levels of CEA, CA19-9, and CA72-4 in patients with radical resection were 75.36(3.76, 198.20)μg/L, 152.76(34.81, 241.09)kU/L, 126.60(4.01, 218.07)kU/L, respectively.The expression levels of CEA, CA19-9, and CA72-4 in the radically resected patient group were 173.65(120.78, 254.87) μg/L, 255.88(102.45, 395.11) kU/L, 201.71(79.15, 325.92)kU/L.The expression level of CEA, CA19-9, CA72-4 in the group with radical resection were lower than that in the group with no radical resection, and the difference was statistically significant (the Z values were 10.672, 8.945, 9.862, all P<0.001). ROC curve showed that AUC of CEA, CA19-9 and CA72-4 were 0.627, 0.714 and 0.768, respectively.The best cut-off value of CA72-4 was 87.62 kU/L, the sensitivity was 88.1% (74/84) and the specificity was 90.4% (47/52). Conclusion:The expression levels and number of tumor markers CEA, CA19-9, CA72-4 in patients with gastric cancer were correlated with the risk of radical resection.
