ABSTRACT

IgA nephropathy is recognized as the most common primary glomerular disease, with up to 20%-40% of patients developing end-stage kidney disease within 20 years of onset. The deposition of IgA1-containing immune complexes targeting glycosylation defects in the mesangial region and the subsequent inflammation caused by T lymphocyte activation are considered as the main causes of IgA nephropathy, and innate immunity is also involved in the pathogenesis. Nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) is a newly discovered pattern recognition receptor expressed in renal intrinsic cells such as renal tubular epithelial cells, mesangial cells, and podocytes. Activated by external stimuli, NLRP3 can form NLRP3 inflammasomes with apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC). The NLRP3 inflammasome can activate cysteine aspartate-specific protease-1 (Caspase-1), causing the maturation and release of interleukin-18 (IL-18) and interleukin-1β (IL-1β) involved in inflammation. Increasing evidence has suggested that NLRP3 inflammasomes are involved in the pathogenesis and progression of IgA nephropathy and associated with the damage of renal intrinsic cells such as podocytes, mesangial cells, endothelial cells, and renal tubular epithelial cells. Chinese medicine can regulate inflammatory cytokines and their signaling pathways by acting on NLRP3 inflammasomes and related molecules, exerting therapeutic effects on IgA nephropathy. This article introduces the role of NLRP3 inflammasomes in IgA nephropathy and reviews the clinical and experimental research progress of Chinese medicine intervention in IgA nephropathy via NLRP3 inflammasomes, aiming to provide a reference for further research and application of Chinese medicine intervention in the NLRP3 inflammasome as a new therapeutic target.

ABSTRACT

OBJECTIVE@#To compare the clinical efficacy and safety between syndrome-differentiation acupuncture combined with rehabilitation training and simple rehabilitation training for children with autism spectrum disorder (ASD).@*METHODS@#A total of 60 children with ASD were randomly divided into an observation group and a control group, 30 cases in each group. In the control group, routine rehabilitation training was applied; in the observation group, syndrome-differentiation acupuncture (the main points were Baihui [GV 20], Dingshenzhen, Niesanzhen, etc., the supplementary acupoints were selected according to syndrome-differentiation) combined with rehabilitation training were applied, all the treatments were given once a day, 5-day continuous treatment with 2-day interval, 12 weeks were required. Before treatment and after 6, 12 weeks of treatment, the autism treatment evaluation checklist (ATEC), childhood autism rating scale (CARS) and autism behavior checklist (ABC) scores were observed, the therapeutic effect and safety were evaluated in the two groups.@*RESULTS@#After 6 and 12 weeks of treatment, except for the sensory perception score after 6 weeks of treatment in the control group, the item scores and total scores of ATEC, CARS scores and ABC scores were decreased compared with those before treatment in the two groups (P<0.05). After 6 weeks of treatment, the social score and total score of ATEC, CARS score in the observation group were lower than those in the control group (P<0.05); after 12 weeks of treatment, the item scores and total score of ATEC, CARS score and ABC score in the observation group were lower than those in the control group (P<0.05). The total effective rate in the observation group was 80.0% (24/30), which was higher than 56.7% (17/30) in the control group (P<0.05). There was no serious adverse reactions in the two groups, and there was no significant difference in the incidence rate of adverse reactions between the two groups (P>0.05).@*CONCLUSION@#Syndrome-differentiation acupuncture combined with rehabilitation training could improve the core symptoms in children with ASD, especially sensory perception and social ability, and with good safety, which is superior to simple rehabilitation training.

ABSTRACT

Objective:To investigate the clinical efficacy of radical resection of rectal cancer with different surgical approaches and influencing factors of postoperative complications.Methods:The retrospective study was conducted. The clinicopathological data of 3 418 patients who underwent radical resection of rectal cancer in the Second Affiliated Hospital of Harbin Medical University from July 2011 to September 2020 were collected. There were 2 060 males and 1 358 females, aged (61±11)years. Patients meeting the requirements of radical resection and surgical indications underwent surgeries choosing from open radical colorectal cancer surgery, laparoscopic radical colorectal cancer surgery, and natural orifice specimen extraction surgery (NOSES). Observation indicators: (1) intraoperative and postoperative conditions of patients undergoing different surgical approaches; (2) comparison of preoperative clinical characteristics in patients undergoing different surgical approaches; (3) comparison of postoperative histopathological characteristics in patients undergoing different surgical approaches; (4) postoperative complications of patients undergoing different surgical approaches; (5) analysis of influencing factors of postoperative complications. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represented as M(range), and comparisons between groups was analyzed using the Kruskal-Wallis rank test. Comparison of ordinal data was analyzed using the non-parameter rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Multivariate analysis was conducted using the Logistic regression model. Results:(1) Intraoperative and postoperative conditions of patients undergoing different surgical approaches. Of the 3 418 patients, 1 978 cases underwent open radical colorectal cancer sur-gery, 1 028 cases underwent laparoscopic radical colorectal cancer surgery and 412 cases underwent NOSES, respectively. The operation time, volume of intraoperative blood loss, cases with permanent stoma, preventive stoma or without fistula, time to postoperative first flatus, time to postoperative liquid food intake, cases transferred to intensive care unit after surgery, duration of postoperative hospital stay were 145(range, 55?460)minutes, 100(range, 30?1 000)mL, 435, 88, 1 455, 72(range, 10?220)hours, 96(range, 16?296)hours, 158, 10(range, 6?60)days, respectively, in patients undergoing open radical colorectal cancer surgery. The above indicators were 175(range, 80?450)minutes, 50(range, 10?800)mL, 172, 112, 744, 48(range, 14?120)hours, 72(range, 38?140)hours, 17, 9(range, 4?40)days, respectively, in patients undergoing laparoscopic radical colorectal cancer surgery and 180(range, 80?400)minutes, 30(range, 5?500)mL, 0, 45, 367, 48 (range, 14?144)hours, 72(range, 15?148)hours, 1, 6(range, 3?30)days, respectively, in patients undergoing NOSES.

(2) Com-parison of preoperative clinical characteristics in patients undergoing different surgical approaches. The gender, age, body mass index, cases with diabetes, cases with hypertension, cases with coronary heart disease, cases with anemia, cases with hypoproteinemia, cases with intestinal obstruction, tumor location, preoperative carcinoembryonic antigen, preoperative CA19-9 showed significant differences among patients undergoing open radical colorectal cancer surgery, laparoscopic radical colorectal cancer surgery and NOSES ( P<0.05). (3) Comparison of postoperative histopathological characteris-tics in patients undergoing different surgical approaches. Tumor histological type, tumor differentiation degree, tumor diameter, number of lymph node detected, nerve invasion, vascular invasion, lymph node invasion, tumor T staging, tumor N staging, tumor M staging, tumor TNM staging showed significant differences among patients undergoing open radical colorectal cancer surgery, laparos-copic radical colorectal cancer surgery and NOSES ( P<0.05). (4) Postoperative complications of patients undergoing different surgical approaches. Cases with postoperative complications as anastomotic leakage, abdominal infection, intestinal obstruction, anastomotic bleeding, incision complications, pulmonary infection, other complications were 52, 21, 309, 8, 130, 51, 59, respectively, in patients undergoing open radical colorectal cancer surgery. The above indicators were 33, 17, 75, 3, 45, 58, 9, respectively, in patients undergoing laparoscopic radical colorectal cancer surgery and 13, 4, 8, 0, 11, 10, 15, respectively, in patients undergoing NOSES. There were significant differences in the intes-tinal obstruction, incision complications, pulmonary infection, other complications among patients undergoing different surgical approaches ( χ2=122.56, 13.33, 20.44, 15.59, P<0.05) and there was no significant difference in the anastomotic leakage, abdominal infection, anastomotic bleeding among patients undergoing different surgical approaches ( χ2=0.96, 2.21, 3.08, P>0.05). (5) Analysis of influencing factors of postoperative complications. ① Analysis of influencing factors of intestinal obstruction in patients with radical resection of rectal cancer. Age as 20?39 years and 40?59 years, surgical approach as laparoscopic radical colorectal cancer surgery and NOSES were independent protective factors of intestinal obstruction in patients with radical resection of rectal cancer ( odds ratio=0.46, 0.59, 0.43, 0.13, 95% confidence interval as 0.21?1.00, 0.36?0.96, 0.33?0.56, 0.06?0.27, P<0.05). ② Analysis of influencing factors of incision complications in patients with radical resection of rectal cancer. Body mass index as 24.0?26.9 kg/m 2, surgical approach as laparoscopic radical colorectal cancer surgery and NOSES were independent protective factors of incision complications in patients with radical resection of rectal cancer ( odds ratio=0.24, 0.63, 0.46, 95% confidence interval as 0.11?0.51, 0.44?0.89, 0.24?0.87, P<0.05). ③ Analysis of influencing factors of pulmonary infection in patients with radical resection of rectal cancer. The surgical approach as laparoscopic radical colorectal cancer surgery was an independent risk factor of pulmonary infection in patients with radical resection of rectal cancer ( odds ratio=2.15, 95% confidence interval as 1.46?3.18, P<0.05), and tumor TNM staging as 0?Ⅰ stage was an independent protective factor ( odds ratio=0.10, 95% confidence interval as 0.01?0.88, P<0.05). ④ Analysis of influencing factors of other complica-tions in patients with radical resection of rectal cancer. Age as 20?39 years, 40?59 years, 60?79 years, body mass index as <18.5 kg/m 2, 18.5?23.9 kg/m 2, 24.0?26.9 kg/m 2, 27.0?29.9 kg/m 2, surgical approach as laparoscopic radical colorectal cancer surgery were independent protective factors of other complications in patients with radical resection of rectal cancer ( odds ratio=0.10, 0.29, 0.37, 0.08, 0.22, 0.35, 0.32, 0.29, 95% confidence interval as 0.01?0.81, 0.13?0.64, 0.17?0.78, 0.02?0.40, 0.09?0.52, 0.15?0.83, 0.12?0.89, 0.14?0.59, P<0.05). Conclusions:Compared to laparoscopic radical colorectal cancer surgery and NOSES, open radical colorectal cancer surgery has wide indication and short operation time, but less perioperative treatment effect. Laparoscopic radical colorectal cancer surgery and NOSES can achieve better surgical result and less postoperative complication when patients meeting surgical indications.

ABSTRACT

Objective:To investigate the effect of Stigma Maydis Palysaccharide(SMPS)on ATP synthesis in kidney mitochondria of D-galactose-induced aging mice, and to clarify its possible mechanism.Methods:The aging mouse model was established by subcutaneous injection of D-galactose solution in the back of the neck.The 48 SPF male mice were randomly divided into normal control group(control group), D-galactose model group(D-Gal group), SMPS low-dose group and SMPS high-dose group(n=12 for each). The control group was subcutaneously injected with 150 mg/kg normal saline on the back of the neck every day, while the other three groups were subcutaneously injected with 150 mg/kg of D-gal solution on the back of the neck every day.SMPS-L and-H dose groups were given 30 mg/kg and 60 mg/kg of SMPS solution by gavage at the same day of D-Gal injection.The control group and D-GAL group were given the same volume of normal saline daily by gavage for 42 days.Blood samples were collected from the eyeball under general anesthesia after 42 days of intervention for the detection of serum levels of superoxide dismutase(SOD), glutathione peroxidase(GSH-Px)and MDA.After harvesting the kidney tissue, various tests were used to detect ATP content, the mRNA expression levels and protein expression levels in kidney.Luciferase assay was used to detect ATP content in renal tissue.Real-time fluorescent quantitative PCR was used to detect the mRNA expression levels of succinate dehydrogenase(SDH)of complex Ⅱ, cytochrome C reductase(Cycs)of complex Ⅲ, complex Ⅳ(COXⅣ)and ATP5b in ATP synthase in mitochondrial oxidative respiratory chain.Western blot was used to detect the expression levels of mitochondrial fusion protein 2(MFN2), dynamin-related protein1(DRP1)and mitochondrial autophagy related protein P62 in renal tissues of each group.Results:Compared with control group, the activities of serum of SOD(116.53±10.01)U/mg and GSH-Px(127.58±8.74)μmol/L were significantly decreased in D-GAL group(both P< 0.01), and serum MDA content(15.42±0.91)μmol/L increased significantly in D-GAL group( P<0.01). Compared with D-GAL group, the activities of SOD(152.80±9.29)U/mg and GSH-Px(274.07±10.73)μmol/L were significantly increased in SMPS intervention group( P< 0.01), while the MDA content(8.10±0.66)μmol/L decreased significantly in SMPS intervention group( P< 0.01). Compared with control group, the content of ATP(178±4)10 -4 μmol in D-gal group was significantly decreased( P<0.01), the mRNA expression levels of SDH, Cycs and COXⅣ were not significantly changed in D-gal group, and the mRNA expression level of ATP5b(0.67±0.01)was down-regulated in D-gal group( P<0.01), the expression of MFN2 protein(0.29±0.02)was significantly decreased in D-gal group( P<0.01), and the expression of DRP1 and P62 protein(0.31±0.02 and 0.21±0.01)was significantly increased in D-gal group(both P<0.01). Compared with the D-gal group, the ATP content(193±1)10 -4 μmol in the kidney tissue of the mice was significantly increased in SMPS intervention group( P< 0.01), and the ATP5b mRNA expression and MFN2 protein expression(0.87±0.05 and 0.71±0.08)were significantly increased in SMPS intervention group(both P< 0.01), DRP1 and P62 protein expressions(0.20±0.01 and 0.10±0.01)were significantly down-regulated in in SMPS intervention group(both P< 0.01). Conclusions:SMPS can improve the mitochondrial dynamic homeostasis disorder in aging mice by increasing the activity of antioxidant enzymes, up-regulating the expression of ATP5b mRNA and MFN2 protein, down-regulating the expression of DRP1 and P62 protein, and promoting the generation of mitochondrial ATP in D-gal-induced aging mice kidney tissue.

ABSTRACT

The main goal of radioactive iodine (RAI) administrated for patients with indeterminate-risk differentiated thyroid cancer (DTC) is removing occult microscopic residual disease after a total thyroidectomy, aiming to reduce recurrence and metastasis, then to improve disease-free survival. This treatment is called as adjuvant therapy, which also ablates the remnant thyroid tissue together. According to the current thyroid cancer management guidelines (2015 American Thyroid Association management guidelines), intermediate-risk patients can be selectively administered RAI. By reviewing articles about DTC patients with indeterminate-risk who underwent RAI or not after thyroidectomy, this article shows that there are inconsistent opinions on 131I decreasing recurrence and improving survival. In addition, apart from unexplained hyperthyroglobulinemia as an indication for 131I therapy, no other uniform clinicalpathological characteristics are recommended.

ABSTRACT

OBJECTIVE@#To compare the effect of acupuncture based on syndrome differentiation and estazolam in the treatment of chronic insomnia and its influence on cognitive function.@*METHODS@#A total of 90 patients with chronic insomnia were randomly divided into an acupuncture group and a medication group, 45 cases in each group. The acupuncture group was treated with acupuncture at Sishencong (EX-HN 1) and bilateral Shenmen (HT 7), Sanyinjiao (SP 6) combined with compatibility of acupoints based on syndrome differentiation, once a day for 6 d and then rest for 1 d, for a total of 4 weeks. The medication group was treated with oral estazolam tablets before bedtime, 1 tablet each time, for a total of 4 weeks. Before and after treatment, the scores of Pittsburgh sleep quality index (PSQI), mini-mental state examination (MMSE), Montreal cognitive assessment (MoCA) and auditory verbal memory test (AVMT) of the two groups were compared, and the effects were evaluated.@*RESULTS@#After treatment, the PSQI sub-item scores and total scores of the two groups were lower than those before treatment ( P<0.05 ), and above scores in the acupuncture group were lower than those in the medication group ( P<0.05 ); the scores of MMSE, MoCA and AVMT in the two groups were higher than those before treatment ( P<0.05 ), and the scores in the acupuncture group were higher than those in the medication group ( P<0.05 ). The total effective rate of the acupuncture group was 80.0% (36/45), which was higher than 53.3% (24/45) in the medication group (P<0.05).@*CONCLUSION@#Syndrome differentiation acupuncture can improve the sleep quality and cognitive function of patients with chronic insomnia, and the curative effect is better than that of estazolam.

ABSTRACT

Objective:To study the frequency of SLC26A4 gene mutation sites in children with enlarged vestibular aqueduct deafness in Yunnan, report the new mutation sites of SLC26A4 gene, further clarify the mutation spectrum of SLC26A4gene, and explore the association between biallelic and monoallelic mutations of SLC26A4 gene and CT phenotype of inner ear, so as to provide basis for clinical and genetic diagnosis of deafness. Methods:Review the results of temporal bone CT examination of 390 children after cochlear implantation in the Department of Otolaryngology, Kunming Children's Hospital from August 2016 to September 2021. Sanger sequencing of SLC26A4 gene was performed in 59 children with enlarged vestibular aqueduct. According to the genetic test results, the children who underwent temporal bone CT examination were divided into two groups: SLC26A4 biallelic mutation group(homozygous mutation and compound heterozygous mutation), monoallelic mutation group, and the association with inner ear CT phenotype was analyzed, and the new sites were summarized and analyzed. Results:The c.919-2a>g mutation was the most common mutation in children with enlarged vestibular aqueduct with SLC26A4 gene mutation. Three new variants of SLC26A4 gene were found; CT examination combined with genetic testing found that a part of children with enlarged vestibular aqueduct was associated with SLC26A4 monoallelic mutation or no SLC26A4 gene mutation was detected. Further research is needed to investigate the involvement of other pathogenic factors in the pathogenesis of EVA.

ABSTRACT

OBJECTIVE@#To investigate time-related association between fluid balance and prognosis in sepsis patients.@*METHODS@#A retrospective cohort study was conducted based on the data of sepsis patients in the Medical Information Database for Intensive Care-IV 2.0 (MIMIC-IV 2.0) from 2008 to 2019. Sepsis patients aged ≥ 18 years who were admitted to intensive care unit (ICU) for at least 2 days were included. The daily fluid balance and cumulative fluid balance (CFB) were calculated from days 1 to 7 after ICU admission. According to CFB,the patients were divided into negative fluid balance group (CFB% < 0%), fluid balance group (0% ≤ CFB% ≤ 10%), and fluid overload group (CFB% > 10%). In-hospital mortality was the primary outcome. Multifactorial Logistic regression was used to analyze time-related association between different CFB and the risk of in-hospital mortality in patients with sepsis during 7 days after ICU admission. In addition, subgroup analysis was performed on patients with septic shock and patients with sepsis who stayed in the ICU for 7 days or longer.@*RESULTS@#A total of 11 437 patients with sepsis were included, of which 6 595 were male and 4 842 were female. The mean age was (64.4±16.4) years. A total of 10 253 patients (89.6%) survived and 1 184 patients (10.4%) died during hospitalization. Compared with the survival group, patients in the death group were older, lighter, had higher sequential organ failure assessment (SOFA), simplified acute physiology score II (SAPS II), longer ICU stay, higher incidence of septic shock, and higher proportion of invasive mechanical ventilation, renal replacement therapy (RRT) and vasoactive drugs. In terms of comorbidities, congestive heart failure, renal disease, liver disease, and malignancy were more common in the death group. The death group had a higher daily fluid balance than the survival group during 7 days after ICU admission, the CFB in the two groups gradually increased with length of ICU stay. After adjusting variables such as age, gender, race, SOFA score, SAPS II score, comorbidities, and the use of invasive mechanical ventilation, RRT and vasoactive drugs, multivariate Logistic regression analysis showed that fluid overload on day 1 after ICU admission was a protective factor for the reduced risk of in-hospital mortality in sepsis patients [odds ratio (OR) = 0.74, 95% confidence interval (95%CI) was 0.64-0.86, P = 0.001]. However, fluid overload on day 3 was a risk factor for in-hospital mortality in sepsis patients (OR = 1.70, 95%CI was 1.47-1.97, P < 0.001) and the risk of in-hospital mortality was significantly increased from day 4 to day 7. Furthermore, the same results were obtained in patients with septic shock and sepsis patients who stayed in the ICU for 7 days or longer.@*CONCLUSIONS@#Fluid overload on day 1 was associated with reduced in-hospital mortality. However, from the third day, fluid overload increases the risk of in-hospital mortality. Thus, managing fluid balance at different times may improve prognosis.

ABSTRACT

OBJECTIVE@#To develop a reduction device for the arthroscopy-assisted treatment of tibial plateau fracture and explore its clinical efficacy.@*METHODS@#From May 2018 to September 2019, 21 patients with tibial plateau fracture were treated, including 17 males and 4 females. Their ages ranged from 18 to 55 years old with an average of (38.6±8.7) years old. There were 5 cases of Schatzker typeⅡand 16 cases of Schatzker type Ⅲ. The self-designed reductor combined with arthroscope was used for auxiliary reduction and fixation(minimally invasive percutaneous plate osteosynthesis). The efficacy was analyzed by observing the operation time, blood loss, fracture healing time and knee function(HSS and IKDC scoring criteria).@*RESULTS@#All the 21 patients were followed up for 8 to 24 with an average of(14.0±3.1) months. The operative time ranged from 70 to 95 min with an average of(81.7±7.6)min, incision length ranged from 4 to 7 cm with an average of(5.3±0.9) cm, intraoperative blood loss ranged from 20 to 50 ml with an average of(35.3±5.2) ml, postoperative weight-bearing time ranged from 30 to 50 d with an average of(35.1±9.2) d, fracture healing time ranged from 65 to 90 d with an average of(75.0±4.4) d, and complications were 0 cases, respectively. The fracture was well healed and no screw plate fracture was observed. The knee function scores of HSS and IKDC 18 months after operation were significantly higher than those before operation(P<0.05).@*CONCLUSION@#The custom-made reduction tool for the arthroscopic management of tibial plateau fracture is reasonable in design and simple in operation. The specific reduction tool could effectively reduce the fracture, and shorten the fixation time with minimally invasive procedure.

ABSTRACT

Objective To investigate the value of a risk assessment model in predicting venous thromboembolism (VTE) in patients with liver failure after artificial liver support therapy. Methods A retrospective analysis was performed for the clinical data of 124 patients with liver failure who received artificial liver support therapy in Affiliated Drum Tower Hospital of Nanjing University Medical School from March 2019 to December 2021, among whom there were 41 patients with VTE (observation group) and 143 patients without VTE (control group). Related clinical data were compared between the two groups, and the Caprini risk assessment model was used for scoring and risk classification of the patients in both groups. The t -test was used for comparison of continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups; the Mann-Whitney U rank sum test was used for comparison of ranked data between two groups. The logistic regression analysis was used to investigate the independent risk factors for VTE in patients with liver failure after artificial liver support therapy. The receiver operating characteristic (ROC) curve was used to investigate the value of Caprini score and the multivariate predictive model used alone or in combination in predicting VTE. Results The observation group had a significantly higher Caprini score than the control group (4.39±1.10 vs 3.12±1.04, t =6.805, P < 0.001). There was a significant difference between the two groups in risk classification based on Caprini scale ( P < 0.05), and the patients with high risk or extremely high risk accounted for a higher proportion among the patients with VTE. The univariate analysis showed that there were significant differences between the two groups in age ( t =6.400, P < 0.001), catheterization method ( χ 2 =14.413, P < 0.001), number of times of artificial liver support therapy ( Z =-4.720, P < 0.001), activity ( Z =-6.282, P < 0.001), infection ( χ 2 =33.071, P < 0.001), D-dimer ( t =8.746, P < 0.001), 28-day mortality rate ( χ 2 =5.524, P =0.022). The multivariate analysis showed that number of times of artificial liver support therapy (X 1 ) (odds ratio [ OR ]=0.251, 95% confidence interval [ CI ]: 0.111-0.566, P =0.001), activity (X 2 ) ( OR =0.122, 95% CI : 0.056-0.264, P < 0.001), D-dimer (X 3 ) ( OR =2.921, 95% CI : 1.114-7.662, P =0.029) were independent risk factors for VTE in patients with liver failure after artificial liver support therapy. The equation for individual predicted probability was P =1/[1+e -(7.425-1.384X 1 -2.103X 2 +1.072X 3 ) ]. The ROC curve analysis showed that Caprini score had an area under the ROC curve of 0.802 (95% CI : 0.721-0.882, P < 0.001), and the multivariate model had an area under the ROC curve of 0.768 (95% CI : 0.685-0.851, P < 0.001), while the combination of Caprini score and the multivariate model had an area under the ROC curve of 0.957 (95% CI : 0.930-0.984, P < 0.001). Conclusion The Caprini risk assessment model has a high predictive efficiency for the risk of VTE in patients with liver failure after artificial liver support therapy, and its combination with the multivariate predictive model can significantly improve the prediction of VTE.

Methods: From April to December 2021, the key components of Liangge Powder and its targets against sepsis-induced ALI were analyzed by network pharmacology, and to enrich for relevant signaling pathways. A total of 90 male Sprague-Dawley rats were randomly assigned to sham-operated group, sepsis-induced ALI model group (model group), Liangge Powder low, medium and high dose group, ten rats in the sham-operated group and 20 rats in each of the remaining four groups. Sepsis-induced ALI model was established by cecal ligation and puncture. Sham-operated group: gavage with 2 ml saline and no surgical treatment. Model group: surgery was performed and 2 ml saline was gavaged. Liangge Powder low, medium and high dose groups: surgery and gavage of Liangge Powder 3.9, 7.8 and 15.6 g/kg, respectively. To measure the wet/dry mass ratio of rats lung tissue and evaluate the permeability of alveolar capillary barrier. Lung tissue were stained with hematoxylin and eosin for histomorphological analysis. The levels of tumor necrosis factor-alpha (TNF-α), interleukin (IL) -6 and IL-1β in bronchoalveolar lavage fluid (BALF) were measured by enzyme-linked immunosorbent assay. The relative protein expression levels of p-phosphatidylinositol 3-kinase (PI3K), p-protein kinase B (AKT), and p-ertracellular regulated protein kinases (ERK) were detected via Western blot analysis. Results: Network pharmacology analysis indicated that 177 active compounds of Liangge Powder were selected. A total of 88 potential targets of Liangge Powder on sepsis-induced ALI were identified. 354 GO terms of Liangge Powder on sepsis-induced ALI and 108 pathways were identified using GO and KEGG analysis. PI3K/AKT signaling pathway was recognized to play an important role for Liangge Powder against sepsis-induced ALI. Compared with the sham-operated group, the lung tissue wet/dry weight ratio of rats in the model group (6.35±0.95) was increased (P<0.001). HE staining showed the destruction of normal structure of lung tissue. The levels of IL-6 [ (392.36±66.83) pg/ml], IL-1β [ (137.11±26.83) pg/ml] and TNF-α [ (238.34±59.36) pg/ml] were increased in the BALF (P<0.001, =0.001, <0.001), and the expression levels of p-PI3K, p-AKT and p-ERK1/2 proteins (1.04±0.15, 0.51±0.04, 2.31±0.41) were increased in lung tissue (P=0.002, 0.003, 0.005). The lung histopathological changes were reduced in each dose group of Liangge Powder compared with the model group. Compared with the model group, the wet/dry weight ratio of lung tissue (4.29±1.26) was reduced in the Liangge Powder medium dose group (P=0.019). TNF-α level [ (147.85±39.05) pg/ml] was reduced (P=0.022), and the relative protein expression levels of p-PI3K (0.37±0.18) and p-ERK1/2 (1.36±0.07) were reduced (P=0.008, 0.017). The wet/dry weight ratio of lung tissue (4.16±0.66) was reduced in the high-dose group (P=0.003). Levels of IL-6, IL-1β and TNF-α[ (187.98±53.28) pg/ml, (92.45±25.39) pg/ml, (129.77±55.94) pg/ml] were reduced (P=0.001, 0.027, 0.018), and relative protein expression levels of p-PI3K, p-AKT and p-ERK1/2 (0.65±0.05, 0.31±0.08, 1.30±0.12) were reduced (P=0.013, 0.018, 0.015) . Conclusion: Liangge Powder has therapeutic effects in rats with sepsis-induced ALI, and the mechanism may be related to the inhibition of ERK1/2 and PI3K/AKT pathway activation in lung tissue.

ABSTRACT

Objective:To investigate the diagnostic value of endoscopic ultrasound elastography (EUS-E) in endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for malignant occupying lesions in gastrointestinal adjacent tissue.Methods:Clinical data of 54 patients (57 lesions) undergoing EUS-FNA from January 2020 to April 2021 in the General Hospital of Ningxia Medical University were collected. Thirty patients (31 lesions) who received FNA assisted by EUS-E from May 2020 to February 2021 were enrolled in the EUS-E group, and 24 patients (26 lesions) who underwent routine EUS-FNA without EUS-E in the non-EUS-E group. The diagnostic efficacy of EUS-FNA was evaluated.The diagnostic efficacy of EUS-E group and non EUS-E group was compared. EUS-E score of EUS-E group was analyzed.Results:The overall sensitivity, specificity, positive predictive value, negative predictive value and accuracy of EUS-FNA in the diagnosis of malignant occupying lesions in gastrointestinal adjacent tissue were 80.5% (33/41), 100.0% (16/16), 100.0% (33/33), 66.7% (16/24) and 86.0% (49/57), respectively. There were no significant differences in sensitivity [78.6% (22/28) VS 84.6% (11/13), P=0.232] or accuracy [83.8% (31/37) VS 90.0% (18/20), P=0.156] of EUS-FNA for pancreatic lesions and other lesions (mediastinal and celiac lesions). Postoperative complications occurred in 1 patient (1.85%, 1/54). Also there were no significant differences in sensitivity [84.0% (21/25) VS 81.3% (13/16), P=0.186] or accuracy [87.1% (27/31) VS 88.5% (23/260, P=0.186] of diagnosis of malignant occupying lesions between EUS-E group and non-EUS-E group. In the EUS-E group, EUS-E score≥3 was highly consistent with the definite diagnosis ( Kappa=0.63). Conclusion:EUS-FNA is a safe and effective cytological and pathological method for diagnosis in gastrointestinal adjacent tissue. EUS-E score can well predict benign and malignant lesions, but EUS-FNA assisted by EUS-E does not show superiority in diagnostic sensitivity or accuracy.

ABSTRACT

ObjectiveTo compare and evaluate the clinical efficacy of five classical prescriptions for acute attack of bronchial asthma (BA) and cough variant asthma (CVA) in children, and to further compare and assess the effect of them on cold-induced asthma or heat-induced asthma. MethodRandomized controlled trials (RCT) on the treatment of acute attack of asthma with five classical prescriptions (Sanzi Yangqintang, Maxing Shigantang, Shegan Mahuangtang, Xiao Qinglongtang, and Dingchuantang) were retrieved from China Science and Technology Journal Database (VIP), China National Knowledge Infrastructure (CNKI), and Wanfang Data (from establishment to August 15, 2021). The eligible RCT were evaluated and the data were extracted for network Meta-analysis by Stata 16.0. ResultA total of eligible 47 RCT were screened out, involving 5 114 children with acute attack of asthma and 10 intervention measures. Among them, 16 RCT (1 912 children, 6 intervention measures) were about the cold-induced asthma and 10 RCT (1 054 cases, 4 intervention measures) focused on the heat-induced asthma. According to the Meta-analysis, among the 10 interventions, Maxing Shigantang + routine treatment of western medicine demonstrated the most significant effect, and the effect of the interventions was in the following order: Maxing Shigantang + routine treatment of western medicine > routine treatment of western medicine, Shegan Mahuangtang + routine treatment of western medicine> Xiao Qinglongtang + routine treatment of western medicine > Shegan Mahuangtang > Dingchuantang + routine treatment of western medicine. For the cold-induced asthma, the effect of Shegan Mahuangtang + routine treatment of western medicine was remarkable, and for the heat-induced asthma, the corresponding intervention was Dingchuantang + routine treatment of western medicine. Shegan Mahuangtang was outstanding in improving the percentage of forced expiratory volume in the first second in predicted value (FEV1%). ConclusionThe combination of western medicine with the five prescriptions was more effective than the western medicine alone, particularly the combination with Maxing Shigantang. The combination of Shegan Mahuangtang and western medicine was outstanding in the treatment of cold-induced asthma, while the corresponding intervention for heat-induced asthma was the combination of Dingchuantang and western medicine. However, a large number of RCT with scientific design and higher quality are still needed to verify the conclusion.

ABSTRACT

ObjectiveTo explore the underlying molecular mechanism of Xiaochuanning granules in the treatment of bronchial asthma based on the network pharmacology and experimental verification through the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway on ovalbumin (OVA) sensitization-induced bronchial asthma model in rats. MethodThe main active ingredients and targets of Xiaochuanning Granules were screened out from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine (BATMAN-TCM). The targets related to bronchial asthma were obtained from five disease databases such as GeneCards and Online Mendelian Inheritance in Man (OMIM). The common targets were screened out through the Venn diagram. STRING was used to construct the protein-protein interaction (PPI) network of "compound-disease", and Cytoscape 3.8.0 was used to establish a network of key active ingredients of Xiaochuanning granules and core target genes ("ingredient-gene" network). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed through DAVID. The bronchial asthma model was induced by OVA stimulation in rats. Bronchial and lung tissue inflammation was observed by hematoxylin-eosin (HE) staining, and the enrichment analysis results of the network pharmacology were verified by Western blot. ResultIn this experiment, 232 active ingredients and 4 687 related targets of Xiaochuanning granules were screened out, and 233 common targets of Xiaochuanning granules and bronchial asthma were collected, including eosinophil-derived neurotoxin 1 (EDN1), cyclic AMP response element-binding protein 1 (CREB1), cyclin-dependent kinase inhibitor 1A (CDKN1A), epidermal growth factor receptor (EGFR), mitogen-activated protein kinase 14 (MAPK14), and Akt1. KEGG pathway analysis revealed 186 related signaling pathways, indicating that the PI3K/Akt signaling pathway presumedly played a key role in the treatment of bronchial asthma by Xiaochuanning granules. The animal experiment showed that Xiaochuanning granules relieved the airway inflammation and smooth muscle hyperplasia in rats and down-regulated the gene expression of PI3K and Akt as compared with the conditions in the model group (P<0.05). ConclusionXiaochuanning granules have the characteristics of multi-component, multi-target, and multi-pathway synergistic effect in the treatment of asthma. Xiaochuanning granules may exert anti-inflammatory effects by regulating the expression of genes related to the PI3K/Akt signaling pathway. The present study is expected to provide a theoretical basis for follow-up in-depth research on the complex mechanism of Xiaochuanning granules in the treatment of bronchial asthma.

ABSTRACT

@#Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths, characterized by highly hypoxic tumor microenvironment. Hypoxia-inducible factor-1α (HIF-1α) is a major regulator involved in cellular response to changes of oxygen levels, supporting the adaptation of tumor cells to hypoxia. Bruceine D (BD) is an isolated natural quassinoid with multiple anti-cancer effects. Here, we identified BD could significantly inhibit the HIF-1α expression and its subsequently mediated HCC cell metabolism. Using biophysical proteomics approaches, we identified inhibitor of β-catenin and T-cell factor (ICAT) as the functional target of BD. By targeting ICAT, BD disrupted the interaction of β-catenin and ICAT, and promoted β-catenin degradation, which in turn induced the decrease of HIF-1α expression. Furthermore, BD could inhibit HCC cells proliferation and tumor growth in vivo, and knockdown of ICAT substantially increased resistance to BD treatment in vitro. Our data highlight the potential of BD as a modulator of β-catenin/HIF-1α axis mediated HCC metabolism.

ABSTRACT

Objective:To investigate the relationship between previous bleeding history and poor prognosis of patients with acute upper gastrointestinal bleeding.Methods:This study was a prospective multicentre real-world study (Acute Upper Gastrointestinal Real-word study, AUGUR study). The data of patients with UGIB who were admitted to the emergency department of 20 tertiary hospitals in China from June 30, 2020 to February 10, 2021 were collected. According to the number of previous bleeding history, the patients were divided into three groups (0 time, 1-3 times, and≥4 times). Based on the patient’s demographic data, clinical characteristics, laboratory data, treatment, and outcomes, univariate and logistic regression analysis were performed to investigate the correlation between the number of previous bleeding and the 90-day mortality and rebleeding of patients with gastrointestinal bleeding.Results:A total of 1 072 patients with acute UGIB were included in this study. The all-cause mortality and rebleeding rate of all patients were 10.9% (117/1 072) and 11.8% (129/1 072), respectively. Among them, 712 patients (66.42%) had no previous bleeding, 297 patients (27.71%) had previous bleeding 1-3 times, and 63 patients (5.88%) had previous bleeding≥4 times. In univariate analysis, age, vital signs and consciousness on admission, history of liver cirrhosis, onset with hematemesis, admission hemoglobin, varicose veins bleeding, peptic ulcer bleeding, red blood cell infusion, tracheal intubation and the use of vasopressors after admission were risk factors for the 90-day mortality and rebleeding rate. Multivariate logistic regression analysis showed that patients with previous bleeding≥4 times had a higher risk of the 90-day mortality ( OR=2.17, 95% CI: 1.04-4.57, P=0.040) and rebleeding ( OR=2.32, 95% CI: 1.19-4.53, P=0.013). Conclusions:The history of previous bleeding≥ 4 times can be used as an independent risk factor for the 90-day mortality and rebleeding in patients with acute UGIB.

ABSTRACT

Nanotechnology has emerged as an ideal approach for achieving the efficient chemo agent delivery. However, the potential toxicity and unclear internal metabolism of most nano-carriers was still a major obstacle for the clinical application. Herein, a novel "core‒shell" co-assembly carrier-free nanosystem was constructed based on natural sources of ursolic acid (UA) and polyphenol (EGCG) with the EpCAM-aptamer modification for hepatocellular carcinoma (HCC) synergistic treatment. As the nature products derived from food-plant, UA and EGCG had good anticancer activities and low toxicity. With the simple and "green" method, the nanodrugs had the advantages of good stability, pH-responsive and strong penetration of tumor tissues, which was expected to increase tumor cellular uptake, long circulation and effectively avoid the potential defects of traditional carriers. The nanocomplex exhibited the low cytotoxicity in the normal cells

ABSTRACT

Angelicae Sinensis Radix (Danggui) and Ligusticum Chuanxiong Rhizoma (Chuan Xiong) herb-pair (DC) have been frequently used in Traditional Chinese medicine (TCM) prescriptions for hundreds of years to prevent vascular diseases and alleviate pain. However, the mechanism of DC herb-pair in the prevention of liver fibrosis development was still unclear. In the present study, the effects and mechanisms of DC herb-pair on liver fibrosis were examined using network pharmacology and mouse fibrotic model. Based on the network pharmacological analysis of 13 bioactive ingredients found in DC, a total of 46 targets and 71 pathways related to anti-fibrosis effects were obtained, which was associated with mitogen-activated protein kinase (MAPK) signal pathway, hepatic inflammation and fibrotic response. Furthermore, this hypothesis was verified using carbon tetrachloride (CCl
