RESUMEN

ObjectiveTo investigate the clinical value of serum creatinine-to-cystatin C ratio (CCR) in evaluating the prognosis of hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF). MethodsA retrospective analysis was performed for the clinical data of 130 patients with HBV-ACLF (treatment group) who were hospitalized in Department of Infectious Diseases, The First Affiliated Hospital of Soochow University, from January 2021 to November 2022. According to the treatment outcome, they were divided into survival group with 87 patients and death group with 43 patients; according to the presence or absence of infection, they were divided into infection group with 37 patients and non-infection group with 93 patients. A total of 30 individuals who underwent physical examination during the same period of time were enrolled as control group. Routine blood test results were collected on the day of admission, including white blood cell count, platelet count, neutrophil count, and lymphocyte count; serum creatinine, cystatin C, serum albumin (Alb), and prothrombin time (PT) were observed on the day of admission and on days 5, 10, and 15 of hospitalization, and related indicators were calculated, including CCR, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), prognostic nutritional index (PNI), CCR5 (CCR on day 5 after admission), ΔCCR5 (CCR on day 5 after admission minus CCR on the day of admission), CCR10 (CCR on day 10 after admission), ΔCCR10 (CCR on day 10 after admission minus CCR on day 5 after admission), CCR15 (CCR on day 15 after admission), and ΔCCR15 (CCR on day 15 after admission minus CCR on day 10 after admission). The above indicators were compared between the survival group and the death group and between the infection group and the non-infection group. The Mann-Whitney U test was used for comparison of continuous data between two groups, and the Kruskal-Wallis H test was used for comparison between multiple groups. The univariate and multivariate logistic regression analyses were used to investigate the influencing factors for disease prognosis; the receiver operating characteristic (ROC) curve was used to assess the value of CCR in predicting HBV-ACLF death events, and the DeLong test was used for comparison of the area under the ROC curve (AUC). ResultsThere were significant differences in CCR, NLR, PNI, PT, and Alb at baseline between the treatment group and the healthy control group (all P<0.001), and there were significant differences in CCR, NLR, and PT between the survival group and the death group on the day of admission (all P<0.05). Among the 130 patients with HBV-ACLF, there were 25 in the precancerous stage, 48 in the early stage, 32 in the intermediate stage, and 25 in the advanced stage, and there were significant differences in baseline CCR, PLR, and PT between the patients in different stages of HBV-ACLF (all P<0.05). There were significant differences in ΔCCR5 and NLR between the infection group and the non-infection group (P<0.05), and there were significant differences in ΔCCR5, CCR10, and CCR15 between the survival group and the death group (all P<0.05). The multivariate logistic regression analysis showed that ΔCCR5 (odds ratio [OR]=1.175, 95% confidence interval [CI]: 1.098‍ — ‍1.256, P<0.001), NLR (OR=0.921, 95%CI: 0.880‍ — ‍0.964, P<0.001), and PT (OR=0.921, 95%CI: 0.873‍ — ‍0.973, P=0.003) were independent influencing factors for the prognosis of HBV-ACLF patients. ΔCCR5 had an AUC of 0.774, a sensitivity of 0.687, and a specificity of 0.757, and the AUC of ΔCCR5+PT+NLR was 0.824, which was significantly higher than the AUC of ΔCCR5, NLR, or PT alone (all P<0.05). ConclusionΔCCR5, NLR, and PT can reflect the condition and prognosis of patients with HBV-ACLF and are independent predictive indicators for death events in patients with HBV-ACLF. The combination ofΔCCR5, PT, and NLR has the best predictive efficiency.

RESUMEN

As people's living standards improve, the development trend of diabetes has gradually become severe. Diabetes is a chronic inflammatory disease associated with abnormal expression of nuclear factor-kappa B (NF-κB) in patients. NF-κB exists in various tissue cells and participates in the regulation of a variety of genes related to immune function and inflammation. Varieties of factors can activate NF-κB when the body is stimulated by external factors, so as to produce inflammation and other reactions. Previous studies on NF-κB mainly focus on cancer, and the pathological mechanism of the treatment of diabetes by related signaling pathways and the progress of traditional Chinese medicine (TCM) treatment have not been systematically elaborated on. By referring to the relevant literature in China and abroad, it was found that NF-κB is not isolated in the development and progression of diabetes but is associated with signal molecules related to inflammation, oxidative stress, and energy metabolism, and it is involved in mediating inflammation, pancreatic β cell apoptosis, insulin signal transduction, and other physiological functions. Therefore, blocking the transmission of NF-κB signaling pathway is beneficial to the treatment of diabetes. At present, Western medicine for the treatment of diabetes mainly includes oral hypoglycemic drugs and insulin injections, but the adverse reactions are obvious. TCM has been characterized by multi-target, extensive action, and excellent curative effects in the treatment of diabetes. TCM and its compounds with functions of tonifying Qi and promoting blood circulation, regulating qi and eliminating phlegm, clearing heat and detoxifying, and nourishing Yin and moistening dryness can effectively intervene in the abnormal expression of NF-κB signaling pathway in vivo through anti-inflammatory effects. In this paper, the association between NF-κB signaling pathway and diabetes was summarized, and the modern research progress of TCM intervention of NF-κB signaling pathway in the treatment of diabetes in the past five years was reviewed, so as to lay a laboratory foundation for the study of a new pathological mechanism of diabetes based on NF-κB signaling pathway and provide new targets and research direction for the prevention and treatment of diabetes and development of related TCM.

RESUMEN

This study aims to evaluate the effectiveness and economic efficiency of Biyuan Tongqiao Granules combined with Triamcinolone Acetonide Nasal Spray in the treatment of chronic rhinosinusitis(CRS). The randomized controlled trial(RCT) of Biyuan Tongqiao Granules combined with Triamcinolone Acetonide Nasal Spray in the treatment of CRS was searched against EMbase, PubMed, Cochrane Library, CNKI, VIP, SinoMed, and Wanfang. The efficacy, nasal mucociliary transport time, and safety of the therapy above in the treatment of CRS were analyzed with single-group rate and Meta-analysis, and the economy and sensitivity were evaluated from the perspective of payer. A total of 9 RCTs were included, including 1 145 patients. Meta-analysis showed that compared with Triamcinolone Acetonide Nasal Spray alone, Biyuan Tongqiao Granules combined with Triamcinolone Acetonide Nasal Spray in the treatment of CRS patients increased the effective rate(RR=1.17, 95%CI[1.11, 1.24], P<0.000 01) and shortened the nasal mucociliary transport time(MD=-3.32, 95%CI[-5.86,-0.78], P=0.01), there was no significant difference in the incidence of adverse reactions between the two groups. The incremental cost-effectiveness analysis showed that the treatment costs of the control group and the observation group were 44.15 yuan and 1 044.96 yuan, respectively. In the Biyuan Tongqiao Granules combined with Triamcinolone Acetonide Nasal Spray treatment group, 75.48 yuan was spent to improve the effective rate of CRS by 1%. The one-way sensitivity analysis indicated the days of treatment, the RR of Biyuan Tongqiao Granules combined with Triamcinolone Acetonide Nasal Spray, the price of unit preparation of Biyuan Tongqiao Granules, and the effective rate of Triamcinolone Acetonide Nasal Spray alone had great influence on the incremental cost-effectiveness ratio. In conclusion, Biyuan Tongqiao Granules combined with Triamcinolone Acetonide Nasal Spray improves the therapeutic effect on CRS. The probabilistic sensitivity analysis showed that when the willingness to pay was greater than 7 920 yuan(less than 0.1 of GDP per capita 8 098 yuan), the combined therapy was economically superior to the control. Due to the limited number of articles published, it is necessary to carry out a real-world clinical trial of Biyuan Tongqiao Gra-nules and Triamcinolone Acetonide Nasal Spray in the treatment of CRS, so as to compare the cost-effectiveness of Biyuan Tongqiao Granules and Triamcinolone Acetonide Nasal Spray.

RESUMEN

Objective: To observe the clinical efficacy of herbal cake-partitioned moxibustion for ulcerative colitis (UC) and elucidate its mechanism by targeting the vitamin D receptor (VDR) signaling pathway. Methods: A total of 63 patients with UC were randomly divided into an observation group (30 cases, treated with herbal cake-partitioned moxibustion) and a control group (33 cases, treated with sham herbal cake-partitioned moxibustion). Moxibustion treatment was performed at Qihai (CV6) and bilateral Tianshu (ST25) and Shangjuxu (ST37), 3 times per week for 12 weeks. The total effective rate, visual analog scale (VAS) score for abdominal bloating and pain, and hospital anxiety and depression scale (HADS) score were compared between the two groups. Enzyme-linked immunosorbent assay was used to detect the concentrations of serum C-reactive protein (CRP), 25-hydroxyvitamin D [25(OH)D], and interleukin-12 (IL-12)/interleukin-23 (IL-23) p40. Immunohistochemistry was used to observe the expression levels of VDR and regenerating gene Ⅳ (Reg Ⅳ) proteins in colonic mucosa. The expression levels of VDR, cytochrome p45027B1 (CYP27B1), and Reg Ⅳ mRNAs were detected by real-time fluorescence quantitive polymerase chain reaction. Results: After treatment, the total effective rate in the observation group was 86.7%, which was significantly higher than 51.5% in the control group (P<0.05). After treatment, the VAS scores for abdominal bloating and pain in the observation group were significantly decreased (P<0.01), as well as the HADS-depression subscale (HADS-D) and HADS-anxiety subscale (HADS) scores (P<0.05), while only the VAS score for abdominal pain in the control group was reduced (P<0.05), and the improvements of the scores in the observation group were more significant than those in the control group (P<0.05). After treatment, the serum CRP concentrations in both groups and the IL-12/IL-23 p40 concentration in the observation group were significantly decreased (P<0.05), and the concentrations in the observation group were lower than those in the control group (P<0.05). The expression levels of VDR protein and mRNA in the colon in both groups were all increased (P<0.01), and the expression levels of Reg Ⅳ protein and mRNA and CYP27B1 mRNA were all decreased in the two groups (P<0.05 or P<0.01); the improvements in the observation group were more notable than those in the control group (P<0.05 or P<0.01). Conclusion: Herbal cake-partitioned moxibustion can effectively alleviate abdominal pain and diarrhea in patients with UC, improve depression and anxiety disorders, and regulate the expression of related proteins in the VDR signaling pathway. The mechanism may be related to inhibiting intestinal inflammation by reducing the release of the proinflammatory cytokine IL-12/IL-23 p40.

RESUMEN

Objective:To investigate the diagnostic accuracy of serological indicators and evaluate the diagnostic value of a new established combined serological model on identifying the minimal hepatic encephalopathy (MHE) in patients with compensated cirrhosis.Methods:This prospective multicenter study enrolled 263 compensated cirrhotic patients from 23 hospitals in 15 provinces, autonomous regions and municipalities of China between October 2021 and August 2022. Clinical data and laboratory test results were collected, and the model for end-stage liver disease (MELD) score was calculated. Ammonia level was corrected to the upper limit of normal (AMM-ULN) by the baseline blood ammonia measurements/upper limit of the normal reference value. MHE was diagnosed by combined abnormal number connection test-A and abnormal digit symbol test as suggested by Guidelines on the management of hepatic encephalopathy in cirrhosis. The patients were randomly divided (7∶3) into training set ( n=185) and validation set ( n=78) based on caret package of R language. Logistic regression was used to establish a combined model of MHE diagnosis. The diagnostic performance was evaluated by the area under the curve (AUC) of receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve. The internal verification was carried out by the Bootstrap method ( n=200). AUC comparisons were achieved using the Delong test. Results:In the training set, prevalence of MHE was 37.8% (70/185). There were statistically significant differences in AMM-ULN, albumin, platelet, alkaline phosphatase, international normalized ratio, MELD score and education between non-MHE group and MHE group (all P<0.05). Multivariate Logistic regression analysis showed that AMM-ULN [odds ratio ( OR)=1.78, 95% confidence interval ( CI) 1.05-3.14, P=0.038] and MELD score ( OR=1.11, 95% CI 1.04-1.20, P=0.002) were independent risk factors for MHE, and the AUC for predicting MHE were 0.663, 0.625, respectively. Compared with the use of blood AMM-ULN and MELD score alone, the AUC of the combined model of AMM-ULN, MELD score and education exhibited better predictive performance in determining the presence of MHE was 0.755, the specificity and sensitivity was 85.2% and 55.7%, respectively. Hosmer-Lemeshow test and calibration curve showed that the model had good calibration ( P=0.733). The AUC for internal validation of the combined model for diagnosing MHE was 0.752. In the validation set, the AUC of the combined model for diagnosing MHE was 0.794, and Hosmer-Lemeshow test showed good calibration ( P=0.841). Conclusion:Use of the combined model including AMM-ULN, MELD score and education could improve the predictive efficiency of MHE among patients with compensated cirrhosis.

RESUMEN

Objective:To explore the correlation between protein energy wasting(PEW)and frailty in elderly patients on maintenance hemodialysis(MHD)and influencing factors of frailty.Methods:Clinical data of patients over 60 who had received regular hemodialysis treatment at Beijing Huairou Hospital between September to December 2021 were collected.According to Fried's evaluation criteria, patients were divided into a frailty group and a non-frailty group, and differences between the two groups were compared.Spearman correlation analysis was conducted to assess the correlation between protein energy wasting and frailty.Logistic regression was used to analyze the influencing factors of frailty in elderly patients on MHD.Results:A total of 81 MHD patients enrolled in this study, with 36 in the frailty group.The frailty group was older, had a higher proportion of patients with PEW, and underwent more months of dialysis, with a higher proportion of patients with diabetic nephropathy as the primary disease, having high levels of C-reactive protein(CRP), and having low KT/V, hemoglobin, albumin, body mass index(BMI), mid-arm circumference(MAC)and mid-arm muscle circumference(MAMC), and the differences with the control group were statistically significant(all P<0.05). The Fried frailty phenotype was positively correlated with age( r=0.021, P=0.047), but negatively associated with HGB( r=-0.329, P=0.003), albumin( r=0.021, P=0.047), BMI( r=0.021, P=0.047), TSF( r=-0.274, P=0.013), MAC( r=-0.554, P<0.001)and MAMC( r=-0.293, P=0.008). A Logistic regression equation was constructed using frailty as the dependent variable.The results showed that age, months of dialysis, KT/V, serum albumin and CRP were independent factors influencing the development of frailty in elderly patients with MHD. Conclusions:PEW and frailty coexist and interact with each other in elderly patients with MHD.Clinicians should place emphasis on the assessment of frailty and protein energy wasting in elderly dialysis patients and achieve early detection and intervention to avoid adverse clinical outcomes.

RESUMEN

Objective:To investigate the risk factors for combined coronary microvascular dysfunction (CMD) in patients with ischemia and non-obstructive coronary artery disease (INOCA).Methods:From October 2020 to May 2022, 100 INOCA patients with myocardial ischemic symptoms who underwent coronary angiography (CAG) suggestive of <50% stenosis in all three coronary arteries at the Tenth People′s Hospital of Tongji University were prospectively recruited. Myocardial perfusion imaging (MPI), transthoracic echocardiography and cadmium-zinc-telluride (CZT) SPECT coronary flow quantification were performed in the same month, and 93 INOCA patients (36 males and 57 females, age (63.0±10.9) years) were finally included. CMD was defined as coronary flow reserve (CFR)<2.5. Independent-sample t test, Mann-Whitney U test and χ2 test were used to compare MPI results and left ventricular volume parameters between CMD and non-CMD groups. ROC curve analysis was used to analyze the efficacy of each index in predicting CMD, and independent risk factors for CMD were screened by multivariate logistic regression analysis. Results:Among 93 INOCA patients, 29 were in the CMD group and 64 were in the non-CMD group. The age, proportion of hypertension, left ventricular mass index (LVMI), summed stress score (SSS), summed difference score (SDS), left ventricular internal diameter systolic (LVIDS), interventricular septum thickness (IVST), and left ventricular posterior wall thickness (LVPWT) in the CMD group were higher than those in the non-CMD group ( t values: 2.42-3.76, χ2=8.94, z values: -3.31, -3.41, all P<0.05). ROC curve analysis showed that LVMI, SSS, SDS, LVPWT, IVST and age were significant in predicting CMD (AUCs: 0.67-0.72). Multivariate logistic regression analysis showed that LVMI (odds ratio ( OR)=1.08, 95% CI: 1.01-1.17), SDS ( OR=5.37, 95% CI: 1.95-14.78), hypertension ( OR=5.68, 95% CI: 1.34-24.18) and age ( OR=1.10, 95% CI: 1.03-1.18) were risk factors for CMD. Conclusion:LVMI, SDS, hypertension and age are strongly associated with combined CMD in INOCA patients, which can be used for early risk stratification of INOCA patients.

RESUMEN

Objective:To evaluate the clinical application of water-filling with "four-eyes" sign under the guidance of ultrasound in nasal-jejunum intubation for critical patients.Methods:This study was a randomized controlled trial. Eighty patients who needed indwelling nasobenteric tube were selected from June 2021 to April 2022 in the Department of Critical Care Medicine, Xiangya Hospital, Central South University. They were divided into control group ( n=40) and experimental group ( n=40) by systemic randomization. For the patients in the experimental group, the intubation was performed by water-filling with "four-eyes" sign under the guidance of ultrasound. For the control group, the traditional method was applicated under the guidance of ultrasound. Using abdominal X-ray as the gold standard of successful pylorus posterior catheterization, the result of catheterization, time of operation, efficiency of positioning in the two groups were analyzed and compared. Results:In the experimental group, 38 cases were successfully intubated, 2 were failed; in the control group, 27 cases were successfully intubated, 13 were failed, and all the failed cases in the control group were then successfully intubated again by using method of the experimental group. The success rate of tube placement in the experimental group was 95.0% (38/40), which was higher than 67.5% (27/40) in the control group ( χ2 = 9.93, P<0.05). The average time of operation in the experimental group was (45.2 ± 14.2) min, which was significantly lower than (70.2 ± 17.7) min in the control group, the difference was significantly different ( t=-5.51, P<0.05). The specificity, sensitivity, positive predictive value, negative predictive value and diagnostic rate of nasal-jejunum intubation positioning in the experimental group were 100.0% respectively, higher than 38.4%, 77.7%, 72.4%, 45.4%, 65.0% in the control group; the false positive rate, false negative rate in the experimental group were both 0, lower than 22.2%, 61.5% in the control group, with statistically significant differences( χ2 values were 4.69- 16.97, all P<0.05). Conclusions:Water-filling with "four-eyes" sign under the guidance of ultrasound in nasal-jejunum intubation was a new method which can shorten the operation time and increase the success rate for intubation. It has relatively high positioning accuracy and possess valuable clinical application.

RESUMEN

ObjectiveTo investigate the effect of rutin on the browning of 3T3-L1 preadipocytes and the mechanism. MethodCell counting kit-8 (CCK-8) assay was used to detect the effect of different concentration of rutin (3.125, 6.25, 12.5, 25, 50, 100, 200 μmol·L-1) on 3T3-L1 cell activity, and Western blot to examine the effect of rutin (12.5, 25, 50 μmol·L-1) on the expression of thermogenesis-associated proteins uncoupling protein 1 (UCP1), PR domain containing 16 (PRDM16) and peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α) in adipocytes. After the optimal concentration of rutin was determined, the effect of rutin on lipid droplet formation in adipocytes was observed based on oil red O staining, and the expression of nuclear respiratory factor 1 (NRF1), nuclear respiratory factor 2 (NRF2) and mitochondrial transcription factor A (TFAM), which were the landmark proteins of mitochondrial biosynthesis, was detected by Western blot. ResultCompared with the blank group, 200 μmol·L-1 rutin inhibited 3T3-L1 cell activity (P<0.01). Compared with the blank group, at the concentration of 12.5, 25, 50 μmol·L-1 rutin significantly promoted the expression of thermogenesis-associated proteins (UCP1, PRDM16, and PGC-1α) (P<0.01), which was determined as the optimal concentration. Compared with the blank group, 50 μmol·L-1 rutin significantly increased the immunofluorescence intensity of mitochondrial UCP1 protein in 3T3-L1 cells (P<0.01) and the expression of the markers of mitochondrial biosynthesis (NRF1, NRF2, and TFAM) (P<0.01). In addition, 50 μmol·L-1 rutin significantly inhibited lipid droplet formation of 3T3-L1 adipocytes (P<0.01). ConclusionRutin inhibited lipid droplet deposition in 3T3-L1 adipocytes and increased the expression of thermogenesis-related proteins (UCP1, PRDM16, and PGC-1α) and markers of mitochondrial biosynthesis (NRF1, NRF2, and TFAM), thereby inducing the browning of 3T3-L1 adipocytes. This lays a basis for the development of drugs that safely regulate the browning of white cells.

RESUMEN

Objective To explore the epidemiological characteristics and trend of lung cancer mortality in Suzhou, to predict the future lung cancer mortality by ARIMA model, and to provide a scientific basis for the research of lung cancer prevention and control strategy. Methods The annual change percentage (APC) was used to analyze the annual change trend of lung cancer mortality from 2001 to 2020, and the ARIMA optimal model was employed to predict the lung cancer mortality from 2021 to 2025. Results The average annual crude mortality of lung cancer in Suzhou from 2001 to 2020 was 46.45/100 000, while the standardized mortality was 23.51/100 000. In recent 20 years, the crude mortality showed an upward trend and the standardized mortality showed a downward trend (APC crude rate = 2.51%, APC standardized rate = -0.78% , P < 0.001). The standardized mortality of lung cancer in men was 3.22 times that in women. The mortality of lung cancer in people over 45 years old increased with the increase of age, but the mortality in the 30-59 years old group showed a downward trend year by year. ARIMA model predicted that the annual trend of lung cancer crude mortality will tend to be flat in the next five years. Conclusion The crude mortality rate of lung cancer in Suzhou shows an upward trend, while the standardized mortality rate decreases year by year, suggesting that we should pay attention to the prevention and control of lung cancer in the elderly, accurately identify high-risk population of lung cancer, promote health publicity and education, carry out lifestyle intervention, and popularize the early screening of lung cancer.

RESUMEN

Mother-to-child transmission of hepatitis B virus (HBV) is one of the main ways of transmission and the main cause of chronic hepatitis B after infection. Therefore, preventing mother-to-child transmission of HBV is particularly important in reducing the incidence of chronic hepatitis B. Currently, nucleoside ( acid) analoids ( Nas ) used for mother-to-child blocking of HBV include lamivudine (LAM) , tibivudine (LdT) and tenofovir fumarate ( TDF). Propofol tenofovir fumarate (TAF) has also been used in pregnant chronic hepatitis B pa- tients. This paper summarizes the efficacy, safety and antiviral treatment indications and termination time of the above-mentioned drugs in mother-to-child preventing to provide suggestions for the selection and rational application of mother-to-child preventing Nas.

RESUMEN

Objective To evaluate the effectiveness of comprehensive echinococcosis control measures with emphasis on management of infectious source in Sichuan Province from 2010 to 2022, so as to provide insights into formulation of future control interventions. Methods Data pertaining to comprehensive echinococcosis control measures with emphasis on management of infectious source and echinococcosis surveillance in Sichuan Province from 2010 to 2022 were collected. The effectiveness of comprehensive echinococcosis control measures with emphasis on management of infectious source was evaluated with prevalence of human echinococcosis, detection of newly diagnosed echinococcosis patients, prevalence of Echinococcus infection in domestic dogs, prevalence of cystic echinococcosis in livestock, prevalence of alveolar echinococcosis in small mammals and awareness of echinococcosis control knowledge, and Spearman’s rank correlation analysis. Results The prevalence of human echinococcosis reduced from 1.08% in 2010 to 0.40% in 2022 in Sichuan Province (χ2 = 1 482.97, P < 0.05), with a reduction from 0.30% to 0.02% in the detection of newly diagnosed echinococcosis cases (χ2 = 2 776.41, P < 0.05), a reduction from 15.87% to 0.46% in the prevalence of Echinococcus infection in domestic dogs (χ2 = 20 823.96, P < 0.05), a reduction from 8.05% to 1.07% in the prevalence of cystic echinococcosis in livestock (χ2 = 1 296.02, P < 0.05), and the awareness of echinococcosis control knowledge increased from 50.65% to 95.24% (χ2 = 34 938.63, P < 0.05); in addition, there was a year-specific prevalence rate of alveolar echinococcosis in small mammals (χ2 = 164.07, P < 0.05). Spearman’s rank correlation analysis revealed that the detection of newly diagnosed echinococcosis cases correlated positively with the prevalence of Echinococcus infections in domestic dogs (rs = 0.823, P < 0.05) and the prevalence of cystic echinococcosis in livestock (rs = 0.795, P < 0.05), and correlated negatively with the awareness of echinococcosis control knowledge (rs = − 0.918, P < 0.05), and the prevalence of Echinococcus infection in domestic dogs correlated positively with the prevalence of cystic echinococcosis in livestock (rs = 0.753, P < 0.05) and negatively with the awareness of echinococcosis control knowledge (rs = −0.747, P < 0.05); however, there was no correlation between the prevalence of Echinococcus infections in domestic dogs and the prevalence of alveolar echinococcosis in small mammals (rs = −0.750, P > 0.05). Conclusions The comprehensive echinococcosis control measures with emphasis on management of infectious source had achieved remarkable effectiveness in Sichuan Province; however, the transmission chain of echinococcosis has not been interrupted. Reinforced comprehensive echinococcosis control measures with emphasis on management of infectious source and sustained tracking evaluation of the effectiveness are recommended in Sichuan Province.

RESUMEN

Mulberry (Morus alba L.) leaf is a well-established traditional Chinese botanical and culinary resource. It has found widespread application in the management of diabetes. The bioactive constituents of mulberry leaf, specifically mulberry leaf flavonoids (MLFs), exhibit pronounced potential in the amelioration of type 2 diabetes (T2D). This potential is attributed to their ability to safeguard pancreatic β cells, enhance insulin resistance, and inhibit α-glucosidase activity. Our antecedent research findings underscore the substantial therapeutic efficacy of MLFs in treating T2D. However, the precise mechanistic underpinnings of MLF's anti-T2D effects remain the subject of inquiry. Activation of brown/beige adipocytes is a novel and promising strategy for T2D treatment. In the present study, our primary objective was to elucidate the impact of MLFs on adipose tissue browning in db/db mice and 3T3-L1 cells and elucidate its underlying mechanism. The results manifested that MLFs reduced body weight and food intake, alleviated hepatic steatosis, improved insulin sensitivity, and increased lipolysis and thermogenesis in db/db mice. Moreover, MLFs activated brown adipose tissue (BAT) and induced the browning of inguinal white adipose tissue (IWAT) and 3T3-L1 adipocytes by increasing the expressions of brown adipocyte marker genes and proteins such as uncoupling protein 1 (UCP1) and beige adipocyte marker genes such as transmembrane protein 26 (Tmem26), thereby promoting mitochondrial biogenesis. Mechanistically, MLFs facilitated the activation of BAT and the induction of WAT browning to ameliorate T2D primarily through the activation of AMP-activated protein kinase (AMPK)/sirtuin 1 (SIRT1)/peroxisome proliferator-activated receptor-gamma coactivator 1α (PGC-1α) signaling pathway. These findings highlight the unique capacity of MLF to counteract T2D by enhancing BAT activation and inducing browning of IWAT, thereby ameliorating glucose and lipid metabolism disorders. As such, MLFs emerge as a prospective and innovative browning agent for the treatment of T2D.

RESUMEN

OBJECTIVE To establish HPLC fingerprint of Portulaca oleracea, establish quantitative analysis of multi- components by single-marker (QAMS) method for the content determination of caffeic acid, ferulic acid, genistin and quercetin, and provide reference for quality control of the medicine. METHODS The determination was performed on Eclipse XDB-C18 column with mobile phase consisted of methanol-0.2% phosphoric acid solution (gradient elution) at the flow rate of 1.0 mL/min. The column temperature was 25 °C, and detection wavelength was set at 360 nm. The sample size was 10 μL. HPLC fingerprint of P. oleracea was established according to the above chromatographic conditions. Cluster analysis (CA) and principal component analysis (PCA) were performed for 15 batches of specimens. Using caffeic acid as internal standard, relative correction factors of other three components were calculated by QAMS, and then the component content was calculated on the basis of relative correction factors, which was compared with the external standard method. RESULTS HPLC fingerprints of 15 batches of P. oleracea were calibrated with a total of 17 common peaks, and 4 components (caffeic acid, ferulic acid, genistin, quercetin) were identified; the similarities of 15 batches of samples were greater than 0.890. The results of CA showed that S1-S10 were clustered into one category, and S11-S15 were clustered into one category. The results of PCA revealed that the accumulative contribution rate of the two main components was 92.502%, and the classification results were basically consistent with CA. The linear range of caffeic acid, ferulic acid, genistin and quercetin were 0.003 1-0.157 1, 0.003 6-0.181 7, 0.008 5-0.425 6,0.000 4-0.021 8 mg/mL (R2≥0.999 7); the results of precision, repeatability, stability (24 h) and recovery tests all complied with the requirements of Chinese Pharmacopoeia. The relative correction factors of ferulic acid, genistin and quercetin calculated by QAMS were 1.534, 5.302 and 0.174; there was no significant difference in the contents of components measured between this method and the external standard method. CONCLUSIONS The established HPLC fingerprint combined with QAMS can be used for the quality control of multiple index components in P. oleracea. The origin has a certain influence on the quality of P. oleracea, and the quality of P. oleracea produced in Sichuan is better than that produced in Anhui and Hebei.

RESUMEN

OBJECTIVE@#To observe the effects of Xingnao Kaiqiao (regaining consciousness and opening orifices) acupuncture therapy on the expression of hypoxia-inducible factor 1α (HIF-1α) and Nod-like receptor protein 3 (NLRP3) in cerebral ischemia-reperfusion rats, and to explore the mechanism of acupuncture against cerebral ischemia-reperfusion injury.@*METHODS@#Seventy-two male SD rats were randomly divided into a sham-operation group, a model group, an acupuncture group and a non-point acupuncture group, with 18 rats in each one. Using modified Longa thread embolization method, the rat model of acute focal cerebral ischemia was prepared; and after 2 h ischemia, the reperfusion was performed to prepared the model of cerebral ischemia-reperfusion. Immediately after reperfusion, Xingnao Kaiqiao acupuncture method was applied to bilateral "Neiguan" (PC 6) and "Shuigou" (GV 26) in the acupuncture group, while in the non-point acupuncture group, acupuncture was delivered at non-points and all of the needles were retained for 30 min in these two groups. The samples were collected 24 h after reperfusion in the rats of each group. Zea-Longa neurological deficit score was used to evaluate the degree of cerebral neurological impairment, TTC staining was adopted to observe the volume percentage of cerebral infarction, HE staining was provided to observe the morphological changes of brain, and Western blot was applied for detecting the expression of HIF-1α and NLRP3 proteins in the cerebral cortex on the right side.@*RESULTS@#Compared with the sham-operation group, neurological deficit score and volume percentage of cerebral infarction were increased in the model group (P<0.01), and HIF-1α and NLRP3 protein expression was elevated (P<0.01). Compared with the model group, neurological deficit score and volume percentage of cerebral infarction were decreased (P<0.01), and HIF-1α and NLRP3 protein expression was lower (P<0.01) in the acupuncture group. There was no significant difference in above indexes in the non-point acupuncture group compared with the model group (P>0.05). Compared with the sham-operation group, the brain tissue of the rats in the model group and the non-point acupuncture group was loose and edema, and the nuclei were shriveled. The brain tissue morphology in the acupuncture group was similar to that of the sham-operation group.@*CONCLUSION@#Acupuncture can alleviate cerebral ischemia-reperfusion injury, and its mechanism may be related to the regulation of HIF-1α/NLRP3 signaling pathway to attenuate inflammatory response.

RESUMEN

To understand the current situation of occupational burnout, turnover intention, and professional self-care among social workers under the context of epidemic prevention and control, and the role of professional self-care in the relationship between occupational burnout and turnover intention, this study investigated 1 066 social workers in Fujian Province with Professional Self-Care Practice Scale, and the Burnout Scale. SPSS 26.0 and its PROCESS plug-in analysis were used, the results showed that the proportion of social workers with moderate and severe occupational burnout accounted for 44.22% and 29.99% respectively, the proportion with turnover intention in the past year accounted for 25.67%, and the average score of professional self-care was (22.57±5.98) points. There was a significant positive correlation between occupational burnout and turnover intention (r=0.29, P<0.01). Professional self-care of social workers was significant negatively correlated with occupational burnout (r=-0.46, P<0.01) and turnover intention (r=-0.16, P<0.01). Professional self-care played a moderating role in the relationship between occupational burnout and turnover intention (β=-0.01, P<0.05). This paper indicated that social workers had a high degree of occupational burnout and turnover intention, low level of professional self-care under the context of epidemic prevention and control, and the attention should be paid to the protective role of professional self-care.

RESUMEN

Objective To investigate the prevalence of Echinococcus infections in wild carnivores in Serthar County, Sichuan Province, so as to provide insights into echinococcosis control in local areas. Methods Stool samples were collected from wild carnivores in Serthar County, Sichuan Province in May 2021, and the host sources of stool samples and Echinococcus infections were identified using PCR assays. The prevalence of E. multilocularis, E. granulosus and E. shiquicus infections was estimated in different hosts. Results A total of 583 stool samples were collected from wild carnivores, including 147 stool samples from fox, 154 from wolf, 227 from wild dogs and 11 from lynx. The overall prevalence of E. multilocularis, E. granulosus and E. shiquicus infections was 5.68%, 0.19% and 14.20% in canine stool samples, and no E. granulosus infection was detected in fox stool samples, while the prevalence of E. multilocularis and E. shiquicus infections was 0.68% and 47.62% in fox stool samples (χ2 = 88.41, P < 0.001). No E. granulosus or E. shiquicus infection was detected in wolf stool samples, and the prevalence of E. multilocularis infection was 10.39% in wolf stool samples. The prevalence of E. multilocularis, E. granulosus and E. shiquicus infections was 5.73%, 0.44% and 2.20% in canine stool samples (χ2 = 12.13, P < 0.01). In addition, the prevalence of E. multilocularis infections was significantly higher in wolf stool samples than in canine and fox stool samples (χ2 = 13.23, P < 0.01), and the prevalence of E. shiquicus infections was significantly higher in fox stool samples than in canine and wolf stool samples (χ2 = 187.01, P < 0.001). No Echinococcus infection was identified in 11 lynx stool samples. Conclusions The prevalence of Echinococcus infections is high in wild canines in Serthar County, Sichuan Province. Wolf, wild dog and fox all participate in the wild life cycle of E. multilocularis in Serthar County, and wolf and wild dogs may play a more important role.

RESUMEN

Objective: To investigate the clinicopathological features of pulmonary granular cell tumors (pGCTs) and to improve the diagnostic accuracy of the tumor. Methods: A total of 5 pGCTs were diagnosed from February 2016 to January 2022 at Shanghai Pulmonary Hospital, Tongji University School of Medicine and Fudan University Shanghai Cancer Center, China. Immunohistochemical staining, and analysis of the clinicopathological characteristics were performed. Results: The average age of the pGCTs patients was 46 years (ranging from 24 to 54 years), with 3 females and 2 males. One case occurred in the bronchus with multiple nodules in the lung, 2 cases occurred in the bronchial opening, and 2 cases were solitary nodules in the lung. The maximum diameter of the tumors ranged from 12 to 15 mm (mean size 14 mm). Microscopically, the tumor showed infiltrative growth and consisted of round, oval or polygonal cells. Abundant eosinophilic cytoplasm was noted, and the nucleoli were prominent. None of the 5 cases showed any mitosis or necrosis. Immunohistochemical and histochemical study showed positive staining for S-100 (5/5), SOX10 (5/5), Vimentin (5/5), TFE3 (4/5), PAS (3/5), and amylase-digested-PAS (3/5), while 4 cases were negative for CD68. TFE3 FISH analyses on 2 cases showed that no signal abnormality was detected in these 2 cases. The average proliferation index of Ki-67 was 2.2% (range 0-5%). There was no recurrence in 4 cases of pGCTs with a follow-up time ranging from 2 months to 60 months. Conclusions: pGCTs are very rare tumors, most likely originating from Schwann cells. Immunohistochemical staining is the conventional diagnostic tool for pGCTs diagnosis. Recognition of this entity is essential for pathologists to avoid misdiagnosis and unnecessary treatments.

RESUMEN

Objective: To investigate the applicability of the 2021 WHO classification of thoracic tumors' new grading system for invasive pulmonary adenocarcinoma (IPA) with different clinical stages and its correlation with the characteristics of targeted genes' variation. Methods: A total of 2 467 patients with surgically resected primary IPA in Shanghai Pulmonary Hospital, Shanghai, China from September to December 2020 were retrospectively analyzed. Eligible cases were graded using the new grading system of IPA of the 2021 WHO classification of thoracic tumors. The clinicopathological data and targeted-gene abnormality were collected. The utility of new grading system of IPA in different clinical stages was investigated. The correlation of clinicopathological features and targeted-gene abnormality in different grades of IPA were compared. Results: All 2 311 cases of IPA were included. There were 2 046 cases of stage Ⅰ IPA (88.5%), 169 cases of stage Ⅱ (7.3%), and 96 cases of stage Ⅲ (4.2%). According to the new classification system of IPA, 186 cases (9.1%), 1 413 cases (69.1%) and 447 cases (21.8%) of stage-Ⅰ adenocarcinoma were classified as Grade 1, Grade 2 and Grade 3, respectively. However, there were no Grade 1 adenocarcinomas in stages Ⅱ and Ⅲ cases. Among stage-Ⅱ and Ⅲ IPA cases, there were 38 Grade 2 cases (22.5%) and 131 Grade 3 cases (77.5%), and 3 Grade 2 cases (3.1%) and 93 Grade 3 cases (96.9%), respectively. In stage-Ⅰ cases, no tumor cells spreading through airspace (STAS), vascular invasion or pleural invasion was found in Grade 1 of IPA, while the positive rates of STAS in Grade 2 and 3 IPA cases were 11.3% (159/1 413) and 73.2% (327/447), respectively. There was a significant difference among the three grades (P<0.01). Similarly, the rates of vascular and pleural invasion in Grade 3 IPA cases were 21.3% (95/447) and 75.8% (339/447), respectively, which were significantly higher than those of 1.3% (19/1 413) and 3.0% (42/1 413) in Grade 2 (P<0.01). EGFR mutational rates in Grades 1, 2 and 3 IPA were 65.7% (94/143), 76.4% (984/1 288) and 51.3% (216/421), respectively. The differences among the three grades were statistically significant (P<0.01). No fusion genes were detected in Grade 1 IPA, while the positive rates of ROS1 and ALK fusion genes in Grade 3 were 2.4% (10/421) and 8.3% (35/421), respectively, which were significantly higher than that of 0.5% (7/1 288) and 1.6% (20/1 288) in Grade 2 (P<0.01). In stage-Ⅱ cases, only EGFR mutation rate in Grade 2 adenocarcinoma (31/37, 83.8%) was higher than that in Grade 3 adenocarcinoma (71/123, 57.7%; P<0.01). However, the correlation between the new grade system of IPA and the distribution characteristics of targeted-gene variation cannot be evaluated in stage Ⅲ cases. Conclusions: The new grading system for IPA is mainly applicable to clinical stage-Ⅰ patients. Tumor grades of IPA are strongly correlated with the high-risk factors of prognosis and the distribution features of therapeutic targets. It is of great significance and clinical value to manage postoperative patients with early-stage IPA.
