ABSTRACT

OBJECTIVES@#Postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) are common operative neurocognitive disorders, which places a heavy burden on patients, families and society. Therefore, it is very important to search for preventive drugs. Previous studies have demonstrated that perioperative use of dexmedetomidine resulted in a decrease the incidence of POD and POCD. But the specific effect of dexmedetomidine on elderly patients undergoing hepatic lobectomy and its potential mechanism are not clear. This study aims to evaluate the efficacy of intraoperative use of dexmedetomidine on preventing POD and POCD in elderly patients undergoing hepatic lobectomy and the influence on the balance between proinflammation and anti-inflammation.@*METHODS@#This trial was designed as a single-center, prospective, randomized, controlled study. One hundred and twenty hospitalized patients from January 2019 to December 2020, aged 60-80 years old with American Society of Anesthesiologists (ASA) II-III and scheduled for hepatic lobectomy, were randomly allocated into 3 groups (n=40) using a random number table: A C group, a Dex1 group, and a Dex2 group. After anesthesia induction, saline in the C group, dexmedetomidine [0.3 μg/(kg·h)] in the Dex1 group, and dexmedetomidine [0.6 μg/(kg·h)] in the Dex2 group were infused until the end of operation. The incidences of hypotension and bradycardia were compared among the 3 groups. Confusion Assessment Method (CAM) for assessing POD and Mini Mental State Examination (MMSE) for evaluating POCD were recorded and venous blood samples were obtained for the determination of neuron specific enolase (NSE), TNF-α, IL-1β, and IL-10 at the different time below: the time before anesthesia (T0), and the first day (T1), the third day (T2), the fifth day (T3), and the seventh day (T4) after operation.@*RESULTS@#Compared with the C group, the incidences of bradycardia in the Dex1 group or the Dex2 group increased (both P<0.05) and there was no difference in hypotension in the Dex1 group or the Dex2 group (both P>0.05). The incidences of POD in the C group, the Dex1 group, and the Dex2 group were 22.5%, 5.0%, and 7.5%, respectively. The incidences of POD in the Dex1 group or the Dex2 group declined significantly as compared to the C group (both P<0.05). However, there is no difference in the incidence of POD between the Dex1 group and the Dex2 group (P>0.05). The incidences of POCD in the C group, the Dex1 group, and the Dex2 group were 30.0%, 12.5%, and 10.0%, respectively. The incidences of POCD in the Dex1 group and the Dex2 group declined significantly as compared to the C group (both P<0.05). And no obvious difference was seen in the incidence of POCD in the Dex1 group and the Dex2 group (P>0.05). Compared with the C group, the level of TNF-α and IL-1β decreased and the level of IL-10 increased at each time points (from T1 to T4) in the Dex1 group and the Dex2 group (all P<0.05). Compared with the Dex1 group, the level of IL-1β at T2 and IL-10 from T1 to T3 elevated in the Dex2 group (all P<0.05). Compared with the T0, the concentrations of NSE in C group at each time points (from T1 to T4) and in the Dex1 group and the Dex2 group from T1 to T3 increased (all P<0.05). Compared with the C group, the level of NSE decreased from T1 to T4 in the Dex1 group and the Dex2 group (all P<0.05).@*CONCLUSIONS@#Intraoperative dexmedetomidine infusion can reduce the incidence of POCD and POD in elderly patients undergoing hepatic lobectomy, and the protective mechanism appears to involve the down-regulation of TNF-α and IL-1β and upregulation of IL-10 expression, which lead to rebalance between proinflammation and anti-inflammation.

ABSTRACT

Preventive chemotherapy is one of the pivotal interventions for the control and elimination of schistosomiasis, which is effective to reduce the morbidity and prevalence of schistosomiasis. In order to promote the United Nations' sustainable development goals and the targets set for schistosomiasis control in the Ending the neglect to attain the Sustainable Development Goals: a road map for neglected tropical diseases 2021-2030, WHO released the guideline on control and elimination of human schistosomiasis in 2022, with major evidence-based updates of the current preventive chemotherapy strategy for schistosomiasis. In China where great success has been achieved in schistosomiasis control, the preventive chemotherapy strategy for schistosomiasis has been updated several times during the past seven decades. This article reviews the evolution of the WHO guidelines on preventive chemotherapy and Chinese national preventive chemotherapy schemes, compares the current Chinese national preventive chemotherapy scheme and the recommendations for preventive chemotherapy proposed in the 2022 WHO guideline on control and elimination of human schistosomiasis, and proposes recommendations for preventive chemotherapy during the future implementation of the 2022 WHO guideline, so as to provide insights into schistosomiasis control among public health professionals engaging in healthcare foreign aid.

ABSTRACT

Objective: To understand the incidence of pneumoconiosis in the non-coal mining industry in Jiangsu Province, and provide reference for the prevention and control of pneumoconiosis in the non-coal mining industry. Methods: The data of 7019 newly diagnosed pneumoconiosis patients in non-coal mining industry in Jiangsu Province from January 1956 to December 2019 were collected through the Jiangsu Province Pneumoconiosis Follow-up Network Report System, including the gender of the pneumoconiosis patients, the name of the employer and the location, the industry classification of the employer, the duration of dust exposure in dust exposure, the name of occupational pneumoconiosis disease, the date of diagnosis of pneumoconiosis, etc. The collected case data of patients with pneumoconiosis were entered into the statistical software, and the characteristics of the patients' diagnosis time, region and industry were analyzed. Results: The number of confirmed pneumoconiosis patients in the non-coal mining industry in Jiangsu Province was mostly in 2007 (395 cases) , concentrated in Wuxi City (40.96%, 2875/7019) and Suzhou City (27.72%, 1946/7019) . The industries to which the patients belonged were mainly non-metallic mining and dressing (60.95%, 4278/7019) , and the most common type of pneumoconiosis was silicosis (96.40%, 6766/7019) . The patients were mainly stageⅠpneumoconiosis (61.33%, 4305/7019) . There were statistically significant differences in the mean age of diagnosis and the average duration of dust exposure among patients with different pneumoconiosis stages (P<0.01) . The differences in the average diagnosis age and the average duration of dust exposure of patients with different types of pneumoconiosis were statistically significant (P<0.05) , the mean age of diagnosis and the average duration of dust exposure of electric welders were the smallest, which were (44.92±7.74) years old and (17.38±10.15) years, respectively. Conclusion: The regional and industry distribution characteristics of new pneumoconiosis patients in the non-coal mining industry in Jiangsu Province are obvious, and attention should be paid to the treatment of pneumoconiosis patients with young diagnosed age and short duration of dust exposure, as well as the personal protection and health protection of front-line workers such as electric welders who are exposed to productive dust in a short period of time.

ABSTRACT

Objective: To explore the mediating effect of job burnout of nursing staff in clinical departments on occupational stress and anxiety, and to provide scientific basis for the formulation of intervention measures to relieve anxiety. Methods: From November 2020 to January 2021, a cross-sectional survey was conducted to investigate the basic situation, occupational stress, job burnout and anxiety of 653 nursing staff in a third class A general hospital in Hebei Province. Spearman rank correlation was used to analyze the relationship between occupational stress, job burnout and anxiety, stepwise regression and mediating effect model were used to verify the mediating effect of job burnout on the relationship between occupational stress and anxiety. Results: 551 valid questionnaires were collected with effective recovery of 84.38%. The incidence of high occupational stress was 68.06% (375/551) , the incidence of job burnout was 63.70% (351/551) [high, moderate and moderate were 11.07% (61/551) and 52.63% (290/551) respectively], and the incidence of anxiety was 55.72% (307/551) [mild, moderate and severe were 38.11% (210/551) , 8.53% (47/551) and 9.08% (50/551) respectively]. Occupational stress was positively correlated with job burnout and anxiety (r=0.545, 0.479) , and job burnout was positively correlated with anxiety (r=0.542, P<0.05) . The mediating effect analysis showed that occupational stress had a statistically significant effect on anxiety (c=0.509, P<0.001) , and the mediating effect of job burnout on the relationship between occupational stress and anxiety accounted for 44.99% of the total effect. Conclusion: The anxiety level of the nursing staff in this third-class A general hospital was relatively high. Job burnout has a mediating effect between occupational stress and anxiety, and anxiety of nursing staff can be alleviated by reducing occupational stress or job burnout.

ABSTRACT

Objective: To analyze the work indicators of China Comprehensive AIDS Response Program (China CARES) and provide reference for future work of the program. Methods: The scores of each indicator were calculated, and different scores among different types of program areas were compared. The M(Q1,Q3) was used to describe the score of each indicator. The entropy weight method was used to calculate the composite score of each indicator and the composite score was translated into a 100-point system and compared among indicators. Results: In terms of the first-level indicators, organizational leadership and management (96.0 points), publicity and education (94.0 points), and innovative strategies and measures (98.0 points) got relatively high scores; while comprehensive social governance of AIDS prevention (72.0 points) was with the lowest score. The scores of publicity and education and comprehensive intervention in county-level program areas were significantly lower than those in urban areas. For secondary indicators, the indicator with relatively lower scores included "condom use among female sex workers last time" (70.0 points)", "at least one local key population has an increase in the number of people receiving HIV testing compared with the previous year" (70.0 points)", "colleges and occupational schools set up AIDS-related self-service facilities" (65.0 points), "HIV testing among the arrested people suspected of prostitution, adultery, drug users and traffickers" (55.0 points) and "condom use among men who have sex with men during last episode" (50.0 points). The "indicator 3 comprehensive intervention" contributed most to the evaluation, while "indicator 7 innovation strategies and measures" played a minor role in the evaluation results. Conclusions: The overall situation of AIDS Response Program in 2020 was good, but the progress in different word areas was not yet balanced. The two areas of comprehensive intervention and comprehensive social governance of AIDS prevention should be strengthened. It is also suggested that relevant indicators be adjusted appropriately to improve evaluation indicators system and comprehensively promote the program.

ABSTRACT

This study aims to systematically evaluate the efficacy and safety of Shuxuetong Injection in the treatment of stroke in progressive. Randomized controlled trials of Shuxuetong Injection in the treatment of stroke in progressive were searched from CNKI, Wanfang, VIP, CMB, PubMed and EMbase. After strict literature screening, data extraction and quality evaluation, a total of 22 articles were included for analysis by RevMan 5.3. The Meta-analysis showed that Shuxuetong Injection combined with conventional treatment was superior to the conventional treatment alone in the major outcome indicators including effective rate(RR=1.27, 95%CI[1.20, 1.33], Z=9.18, P<0.000 01), deterioration rate(RR=0.38, 95%CI[0.22, 0.68], Z=3.31, P=0.000 9), NIHSS scores(MD=-3.89, 95%CI[-4.34,-3.43], Z=16.83, P<0.000 01), CSS scores(MD=-5.59, 95%CI[-6.42,-4.76], Z=13.20, P<0.000 01) and activity of daily living scores(MD=12.02, 95%CI[10.31, 13.72], Z=13.83, P<0.000 01), mortality during treatment was not increased(RR=0.40, 95%CI[0.13, 1.26], Z=1.56, P=0.12). Moreover, Shuxuetong Injection combined with conventional treatment further reduced the secondary outcome indicators including fibrinogen(MD=-0.35, 95%CI[-0.58,-0.13], Z=3.09, P=0.002), triglyceride(MD=-0.38, 95%CI[-0.67,-0.10], Z=2.65, P=0.008), low density lipoprotein cholesterol(MD=-0.72, 95%CI[-0.83,-0.61], Z=12.64, P<0.000 01), serum hypersensitive C-reactive protein(MD=-4.41, 95%CI[-6.96,-1.86], Z=3.38, P=0.000 7), and interleukin-6(MD=-5.43, 95%CI[-6.91,-3.96], Z=7.22, P<0.000 01). GRADE evaluation results showed that the major outcome indicators had low quality of evidence. Shuxuetong Injection in the treatment of stroke in progressive can improve the clinical effective rate, reduce the deterioration rate, improve the neurological function and activity of daily living, down-regulate the levels of fibrinogen, triglyceride, low density lipoprotein cholesterol and alleviate the inflammatory response. Although most studies have reported no adverse reactions, there are selective reports. The safety of Shuxuetong Injection needs to be further verified by more high-quality randomized controlled trial.

ABSTRACT

Objective:To explore the prevalence of passenger lymphocyte syndrome(PLS) after liver transplantation, minimize the result bias caused by previous multicenter confounding factors, make up for the lack of statistical analysis of PLS and provide reference for a diagnosis and treatment of PLS after liver transplantation.Methods:We reviewed liver transplants performed in our center from 2018 to 2019, searching for cases with minor ABO incompatibility or bidirectional ABO incompatibility. Diagnostic criteria for PLS: laboratory confirmation included biochemical identifiers of hemolysis, positivity of the direct antiglobul in test(DAT), donor attributed anti-recipient antibody in recipient's sera, and exclusion of other causes of decreased HGB(i.e. postoperative infection, acute rejection & surgical blood loss). A total of 666 liver transplants were performed. Among 52 patients with minor ABO incompatibility or bidirectional ABO incompatibility, 10 cases developed PLS(19.23%)and 42 cases did not(80.77%). Statistical comparisons between patients with and without PLS were performed using the chi-square test and Fisher's exact test.Results:There were no statistically significant differences in PLS group subjects in terms of sex, age, blood group, type of incompatibility, type of immunosuppressants and postoperative outcome. There was statistically significant correlation between postoperative blood transfusion and PLS( P< 0.05), and donor blood group B cohort demonstrated a higher risk of PLS than donor blood group A and O cohorts( P< 0.05). Conclusions:PLS is one of the causes for postoperative anemia in liver transplantation, and donor blood group B graft is a risk factor for PLS.

ABSTRACT

OBJECTIVE: To investigate the induction and activation of heparinase by extracellular histones in acute respiratory distress syndrome(ARDS) induced by chlorine in mice.METHODS: The specific pathogen free adult male C57 BL/6 mice were randomly divided into control group, chlorine injured group, histone injured group, anti-histone antibody group and heparinase inhibitor group, with six mice in each group.The mice in the control group and histone injured group were exposed to clean air, and the mice in the other three groups were exposed to chlorine gas at a dose of 580.0 mg/m~3 for 30 minutes by systemic dynamic inhalation.Mice in the histone injured group were injected with 50 mg/kg body weight calf thymus histone by tail vein.One hour before exposure, mice in the anti-histone antibody group were pretreated with 20 mg/kg body weight anti-histone H4 antibody by tail vein injection, and mice in the heparinase inhibitor group were injected with 2 mg/kg body weight OGT2115(heparinase inhibitor). The other three groups were given equal volume of 0.9% sodium chloride solution by tail vein injection. After 24 hours of exposure, arterial blood was collected for blood gas analysis and the lung tissue was collected for histopathological examination. The protein level of heparinase in lung tissue were detected using enzyme-linked immunosorbent assay, and the activity of heparinase were detected by measuring the product of heparan degradation. The protein expression of pro-heparinase and active heparinase were detected by Western blotting.RESULTS: The dyspnea developed of mice in the chlorine injured group and histone injured group, diffuse inflammation occurred in lung tissue, the oxygenation index in arterial blood decreased(all P<0.05), and the protein level and activity of heparinase in lung tissue, as well as the relative expression of pro-heparinase and active heparinase were increased compared with the control group(all P<0.05). The dyspnea, hypoxemia and acute lung injury of mice in the anti-histone antibody group were alleviated, and the protein level of heparinase in lung tissue, as well as the relative expression levels of pro-heparinase and active heparinase were decreased(all P<0.05), compared with chlorine injury group and histone injury group.The dyspnea, hypoxemia and acute lung injury were alleviated in the heparinase inhibitor group, and the activity of heparinase and the relative expression of pro-heparinase in the lung tissue were decreased compared with the chlorine injury group(all P<0.05). CONCLUSION: During the occurrence and development of chlorine-induced ARDS in mice, extracellular histones aggravate lung injury by inducing the expression and activation of heparinase. Acute lung injury can be alleviated by inhibiting the expression and activation of heparinase.

ABSTRACT

Medicinal plants have a long history and play an important role in the prevention and treatment of human diseases. However, the interaction between bioactive components and specific biological targets in many medicinal plants is still unclear. Conventional separation and activity evaluation model of chemical constituents from natural products was time-consuming and laborious, and cannot truly reflect the interaction between the natural conformation of compounds and receptors, so these methods could not meet the urgent needs of modern drug development. Affinity ultrafiltration coupled with liquid chromatography-mass spectrometry (AUF-LC/MS) is a rapid, efficient and precise method focused on identification of bio-components from natural products, it can make up for many shortcomings found in conventional discovery of bio-constituents. However, AUF-LC/MS technology also has some drawbacks in experiments. In this paper, the principle, characteristics and application of AUF-LC/MS in the screening of active ingredients from medicinal plants are systematically reviewed, and its development prospect is prospected, so as to provide scientific basis for rapid and targeted screening of active components from medicinal plants.

ABSTRACT

This study aims to explore the mechanism of fresh Phragmitis Rhizoma against chronic bronchitis airway inflammation. The SD rats of SPF grade were divided into control group, model group, Guilongkechuanning group(GLKCN, 1.125 g·kg~(-1)), high-dose fresh Phragmitis Rhizoma group(LG-HD, 15 g·kg~(-1)), and low-dose fresh Phragmitis Rhizoma group(LG-LD, 7.5 g·kg~(-1)). The chronic bronchitis models of rats in other groups except the control group were induced by the modified smoking method. From the 15 th day of modeling, the rats were given corresponding agents by gavage for 20 consecutive days. After the last administration, the rats were sacrificed for sample collection. Enzyme-linked immunosorbent assay(ELISA) was employed to detect serum transforming growth factor-β(TGF-β) and interleukin-6(IL-6) levels. The protein expression of TGF-β, IL-1β and IL-6 in lung tissue was detected by immunohistochemical method. Masson staining was performed to detect collagen fibers and muscle fibers in lung tissue, and HE staining to detect the pathological changes of lung tissue. Human bronchial epithelial(16 HBE) cells were cultured in vitro, and CCK-8(cell counting kit-8) method was used to detect the cytotoxicity of cigarette smoke extract(CSE) and fresh Phragmitis Rhizoma. After the exposure of 16 HBE cells to 3.5% CSE and appropriate concentration(800, 400 μg·mL~(-1)) of fresh Phragmitis Rhizoma for 24 h, quantitative real-time PCR was conducted to determine the mRNA levels of TGF-β and IL-1β, and Western blot was employed to determine the protein levels of TGF-β and IL-6 in the cells. The rat model of chronic bronchitis induced by smoking was successfully established. Fresh Phragmitis Rhizoma reduced serum TGF-β and IL-6 levels, down-regulated the protein levels of TGF-β, IL-1β, and IL-6 in lung tissue, and alleviated pathological changes and fibrotic lesions in lung tissue. Moreover, it down-regulated the CSE-induced protein expression of TGF-β and IL-6 as well as the mRNA level of TGF-β in 16 HBE cells. These results indicated that fresh Phragmitis Rhizoma could prevent airway inflammation from chronic bronchitis and promote cell repair by inhibiting the TGF-β signaling pathway.

ABSTRACT

To systematically evaluate the efficiency and safety of Tanreqing Injection in the treatment of stroke-associated pneumonia(SAP). Seven domestic and foreign databases(CNKI, Wanfang, VIP, CBM, PubMed, Cochrane Library, EMbase) were retrieved from the establishment to July 2020. According to the inclusion and exclusion criteria, randomized controlled trial of the effect of Tanreqing Injection in the treatment of SAP was selected. NoteExpress software was used to screen out literatures. RevMan 5.4 software was used for data analysis. GRADE system was used to evaluate the evidence quality of the outcome indicators. A total of 1 755 cases in 21 studies were retrieved, including 879 cases in experimental group and 876 cases in control group. In general, the quality of stu-dies received was not high. According to Meta-analysis,(1) in terms of shortening the length of hospital stay, Tanreqing Injection combined with conventional western medicine was better than conventional western medicine(MD=-4.04, 95%CI[-4.43,-3.65], P<0.000 01);(2) in terms of increasing effective rate, Tanreqing Injection combined with conventional western medicine was better than conventional western medicine(RR=1.22, 95%CI[1.17, 1.27], P<0.000 01);(3) in terms of reducing inflammation indicators, Tanreqing Injection combined with conventional western medicine was better than conventional western medicine(MD_(CRP)=-10.75, 95%CI[-15.61,-5.88], P<0.000 01; MD_(WBC count)=-1.62, 95%CI[-2.55,-0.69], P=0.000 6; MD_(PCT)=-0.58, 95%CI[-0.89,-0.26], P=0.000 3];(4) in terms of improving symptoms and signs, Tanreqing Injection combined with conventional wes-tern medicine was better than conventional western medicine(MD_(cough)=-2.73, 95%CI[-4.93,-0.53], P=0.02; MD_(antipyretic)=-1.07, 95%CI[-1.17,-0.98), P<0.000 01];(5) in terms of decreasing the NIHSS scores, Tanreqing Injection combined with conventional western medicine was better than conventional western medicine(MD=-3.02, 95%CI[-4.91,-1.13], P=0.002);(6) in terms of adverse reactions, there was no statistically significant difference between Tanreqing Injection combined with conventio-nal western medicine compared with conventional western medicine treatment(RR=1.19, 95%CI[0.61,2.29], P=0.61). GRADE system showed that the evidence levels of above outcome indicators were low and extremely low. The results proved that Tanreqing Injection combined with conventional western medicine had a good advantage in the treatment of SAP, with better observation indicators better than western medicine conventional treatment, and no increase in the incidence of adverse reactions. However, this study had certain limitations. The overall quality of the included studies was low, which affected the reliability of the results. Therefore, the conclusions of this study shall be used cautiously.

ABSTRACT

This research established the HPLC methods for the determination of perillaketone, perillaldehyde, caffeic acid, scutellarin, and rosmarinic acid in 33 batches of Perillae Folium. Kromasil C_(18)(4.6 × 250 mm, 5 μm) chromatographic column was used, and the mobile phase for determination of the perillaketone and perillaldehyde was methanol-water(55∶45) solution, at a flow rate of 1.0 mL·min~(-1), with the column temperature at 30 ℃. The mobile phase for the determination of caffeic acid, scutellarin and rosmarinic acid was methanol(A)-0.2% phosphoric acid aqueous solution(B) with gradient elution(0-20 min, 25%-30% A; 20-60 min, 30%-43% A). The flow rate was 1.0 mL·min~(-1) and the column temperature was set at 30 ℃. The results showed that the established method can achieve good separation of the five components in samples, with a good linear relationship and high accuracy, indicating that the methods can be used for the determination of Perillae Folium. The results showed that all samples contained five components. And the content of rosmarinic acid(0.04%-1.57%) > scutellarin(0.03%-0.77%) > perillaldehyde(0.02%-0.66%) > perillaketone(0.03%-0.30%) > caffeic acid(0.006%-0.07%). Thirty-three Batches of Perillae Folium can be grouped into 5 categories. There are certain content rules and region specificities under different clusters. Perillaketone, perillaldehyde, and rosmarinic acid can be used as the main markers to evaluate the quality of Perillae Folium.

ABSTRACT

In recent years, the establishment of the commercial grade of Yinpian [traditional Chinese medicine(TCM) pieces for decoction] in the TCM industry has been hotly disputed. In this article, Sophorae Flavescentis Radix(SFR) was selected as a representative example to investigated. Through systematic comparison and analysis, the different grades of SFR slices were traced, verified and evaluated. According to the current published local grade standards of SFR slices, the results showed that the first-class of SFR slices were mostly derived from the wild medicinal materials, the second-class were mostly originated from the cultivated materials in 3-4 years, and the third-class products were from a small number of lateral roots and short-growing years or harsh habitat of wild medicinal materials. On the basis of identifying the sources of different grades of SFR slices, the contents of the active components, including matrine, oxymatrine, oxysophocarpine, sophoridine, N-methyl-cytisine, sophocarpine, were quantitatively determined in typical samples, it was found that the grades were inversely proportional to the contents of active ingredients. In order to ensure the universality of the conclusion, the contents of different grades of commercial SFR slices were determined, and the conclusion was verified as "the commercial grades of SFR slices were inversely linked to their contents of active ingredients". This phenomenon is common in the determination of the commercial grade of Yinpian of radix and rhizome. Therefore, we propose that the method or standard of the commercial grade of Yinpian of radix and rhizome based on the size of Yinpian maybe not proper. Whether and how to classify Yinpian commercial grade is not only a multi-disciplinary issue, especially in combination with clinical efficacy, but also a big problem need to consider the production, commercial circulation and other processes link of quality risk and quality assurance, and should be treated with great caution.

ABSTRACT

As anti-aging ingredients, β-nicotinamide mononucleotide(NMN) and nicotinamide adenine dinucleotide(NAD~+) have attracted worldwide attention in recent years. After oral administration, NMN can be converted into NAD~+ in vivo and the latter is the actual ingredient which exerts anti-aging effect. In order to explore the "rejuvenating and anti-aging" effect of Dendrobium officinale, which was firstly recorded in Shennong's Herbal Classic of Materia Medica, this study established the quantitative method of UPLC-MS/MS for simultaneous determination of NMN and NAD~+ in D. officinale and the congeneric species for the first time, and 34 batches of samples were detected. UPLC conditions are as follows: ACQUITY UPLC HSS T3 column(2.1 mm × 100 mm, 1.8 μm), gradient elution with acetonitrile-0.1% formic acid in water at the flow rate of 0.3 mL·min~(-1), and column temperature of 40 ℃. MS conditions were scanned electrospray ionization source and multiple reaction monitoring mode. The method was verified by systematic methodology. The mean recoveries of NMN and NAD~+ were 77.58% and 80.70%, respectively, with RSD of 3.6% and 4.3%, separately. All results showed that the content of NMN was higher in D. officinale than in the other congeneric species. Particularly, the content in fresh D. officinale stems was as high as 0.931 9 μg·g~(-1). NAD~+ was only found in D. officinale and the content was three times higher than that of NMN. This may be the reason that D. officinale topped the "nine famous anti-aging herbs". In addition, processing method influences the content of NMN and NAD~+ in Dendrobium. Specifically, the content of NMN and NAD~+ was in the order of fresh Dendrobium stems > dried Dendrobium stem segments > spiral or spring-like dried Dendrobium stems.

ABSTRACT

Objective:To study the integrated information nursing mode of perioperative medical care under the multidisciplinary cooperation of hip fracture in the elderly patients, provide reference for perioperative nursing of elderly hip fracture.Methods:A total of 1 019 patients with hip fracture from May 2018 to May 2019 in Beijing Jishuitan Hospital were randomly selected as the study object, and the non synchronous control was used for the study. From May to December 2018, 527 elderly patients with hip fracture in orthopaedic department of general trauma were taken as the control group, adopting the traditional treatment and nursing mode; from January to May 2019, 492 elderly patients with hip fracture in elderly trauma orthopaedics department were taken as the intervention group. Under the multidisciplinary cooperation, the information-based nursing mode of integrated medical care was implemented, and a multidisciplinary integrated medical care team was established. The information-based platform was used to optimize the clinical nursing path, and standardized, individualized and continuous nursing scheme was developed. The time from visit to hospitalization, the time from hospitalization to operation, hospitalization time, incidence of more than moderate pain, incidence of venous thromboembolism, incidence of stress injury, incidence of delirium and satisfaction of patients and their families at discharge were compared between the two groups.Results:The number of patients in the intervention group was higher than that in the control group within 4 and 24 hours. The rate of operation in 48 h increased from 8.0%(42/527) to 50.0%(246/492), and the rate of operation in 1 week increased from 70.0%(369/527) to 99.0%(487/492). Compared with the control group, the incidence of more than moderate pain in the intervention group decreased from 85.0%(448/527) to 2.0%(10/492), the incidence of venous thromboembolism in the hospital decreased from 12.0%(63/527) to 4.1%(20/492), and the incidence of pressure injury in hip fracture in the elderly decreased from 2.1%(11/527) to 0.2%(1/492); the incidence of delirium in the hospital decreased from 21.1%(111/527) to 8.1%(40/492); the hospital stay was shortened from (13.42 ± 3.36) d to (7.26 ± 2.03) d, and the satisfaction of patients and their families increased from 60.9%(321/527) to 95.9%(472/492). There were statistical significance between the two groups (χ 2 values were 4.157-708.006, t value was -35.119, P<0.05 or 0.01). Conclusions:The information-based nursing mode of integrated medical care under the multidisciplinary cooperation can adapt to the development of hip fracture in the elderly, which is conducive to the accelerated rehabilitation of patients.

ABSTRACT

Objective@#To investigate the differential expression of serum-and-glucocorticoid-inducible-kinase-2 (SGK2) in hepatocellular carcinoma (HCC) and normal liver tissues and the related mechanism mediating signal transduction of GSK-3 β / β catenin in HCC cells.@*Methods@#Twenty pairs of matched HCC and normal tissues were collected and the situation of expression of SGK2 mRNA was detected by real-time fluorescence quantitative PCR. Western blot was used to detect the levels of SGK2 protein in human HCC cell lines (Huh-7, SMMC-7721) and normal human liver cell line (L02). SGK2 siRNA was used to transfect human HCC cell lines (SMMC-7721 and Huh-7), and then the protein expression levels of GSK-3 β/ β - catenin was successfully detected with the above-mentioned transfected cell line by western blot. Measurement data were expressed as mean ± standard deviation (±s), and the Student t -test was used as the statistical method.@*Results@#SGK2 mRNA expression was up-regulated in all 20 HCC samples than that of the expression of matched normal liver tissues. SGK2 protein levels were significantly higher in Huh-7 and SMMC-7721 than normal human liver cell lines (P < 0.01). The downregulation of SGK2 expression in human HCC cell lines (SMMC-7721 and Huh-7) had inhibited the expression of unphosphorylated GSK-3 β. In addition, the downregulation of SGK2 expression in HCC cell lines had decreased the dephosphorylation of β - catenin to prevent degradation of the β - catenin proteasome.@*Conclusion@#SGK2 is overexpressed in HCC and mediates GSK-3β/β- catenin signaling in HCC cells.

ABSTRACT

Objective:Meta analysis was used to evaluate the diagnostic value of miRNA-25 in different malignant tumors in Chinese population.Methods:The research on the diagnostic value of miRNA-25 in China national knowledge internet (CKNI), VIP, Wanfang, PubMed and EMBase was searched. The publication time was from the establishment of database to October 2019. After the data was extracted, the Meta.DiSc1.4 software was used for preliminary statistical analysis. The Review Manager 5.3's QUADAS-2 tool was used for quality control of the incoming literature. The STATA 15.0 software was used to analyze whether there was publication bias.Results:A total of 10 articles were included in the study, including 792 cases in the case group and 715 cases in the control group. The combined sensitivity, combined specificity, combined specificity, combined positive likehood ratio(PLR), negative likehood ratio (NLR) were 0.71(95% CI: 0.69-0.74), 0.84(95% CI: 0.81-0.86), 4.29(95% CI: 3.39-5.42), 0.35(95% CI: 0.31-0.40), respectively. Diagnostic odds rate (DOR) was 13.09(95% CI: 9.64-17.78), and the area under curve (AUC) was 0.80(95% CI: 0.77-0.84). Subgroup analysis showed that the diagnostic value of miRNA-25 for different malignant tumors suggested that the lung cancer group had the highest diagnostic value and specificity (DOR=16.418, SPE=0.863). Funnel plot indicated that no significant publication bias was found ( P=0.21). Conclusions:miRNA-25 is highly sensitive and specific to different malignancies, especially lung cancer, and can be used as a potential screening biomarker to assist diagnosis.

ABSTRACT

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the pathogen that caused the global COVID-19 outbreak. The 3C-like protease (3CLpro) of SARS-CoV-2 plays a key role in virus replication and has become an ideal target for antiviral drug design. In this paper, we report the validation and use of bioluminescence resonance energy transfer (BRET) technology to establish a cell-based assay for screening for SARS-CoV-2 virus 3CL protease inhibitors. The results show that the method is able to monitor the cleavage efficiency of 3CL protease with good reproducibility (Z' factor is 0.59), and is consistent with antiviral activity analysis in cell culture. This work demonstrates that this method can be applied to the screening and evaluation of 3CL protease inhibitors, providing a powerful tool for the development of new drugs.
