ABSTRACT
Interleukin-1 receptor associated kinase 4 (IRAK-4), acting as a serine threonine kinase, is considered as a key signal node for the transduction of IL-1R family and TLRs signal pathway. Studies have found that IRAK-4 has a hand in many signal pathways, involving the inflammatory response of human joints, intestines, liver and nervous system, as well as other autoimmune diseases. It is also one of the causes of drug resistance of some cancer cells. Therefore, IRAK-4 tends to be an effective therapeutic target for inflammatory diseases and cancer. The prospects for the development of drugs in this pathway is to develop novel IRAK-4 small molecule inhibitors and investigate their safety and effectiveness, enrich the clinical treatment of inflammatory and cancer diseases finally. This paper classified and summarized the latest research progress on small molecule inhibitors of IRAK-4 signaling pathway according to structures of the compounds, in order to provide assistances and references for the research and development of related drugs.
ABSTRACT
ObjectiveTo investigate the effect of Xinfeng capsules on immunoinflammatory indicators in patients with rheumatoid arthritis （RA） due to spleen deficiency and dampness exuberance. MethodA total of 102 patients were randomly divided into control group and observation group according to the random number table method， with 51 cases in each group. All patients were treated with methotrexate tablets， while those in the observation group received additional Xinfeng capsules. The course of treatment in both groups was 12 weeks. The 28-joint disease activity score （DAS28）， visual analogue scale （VAS） scores， morning stiffness time， erythrocyte sedimentation rate （ESR）， high-sensitivity C-reactive protein （hs-CRP）， rheumatoid factor （RF）， anti-cyclic citrullinated peptide （anti-CCP） antibody， vascular endothelial growth factor （VEGF）， and serum amyloid A （SAA） of the two groups before and after treatment were compared. The efficacy and incidence of adverse events were compared between the two groups. The Apriori association rule model and random walk model were constructed to evaluate the effect of Xinfeng capsules in improving hs-CRP， ESR， RF， SAA， VEGF， and anti-CCP. ResultThere were no dropouts in this study. There was no statistical difference in the indicators between the two groups before treatment. After 12 weeks of treatment， the total effective rate in the observation group was 90.19% （46/51）， which was higher than 74.51% （38/51） in the control group （χ2＝4.320，P<0.05）. DAS28， VAS score， and morning stiffness time in the observation group were improved compared with those in the control group （P<0.05）. Apriori association rule model results showed that the application of Xinfeng capsules in the observation group had a strong correlation with the reduction of RF， ESR， hs-CRP， SAA， and VEGF. The results of the random walk model showed that the improvement coefficients of hs-CRP， ESR， RF， SAA， and VEGF in the observation group were all better than those of the control group， and the improvement coefficient of anti-CCP in the control group was better than that of the observation group. The improvement degree of hs-CRP， ESR， RF， SAA， and VEGF in the observation group was superior to that of the control group （P<0.05）. The incidence of adverse reactions in the observation group was lower than in the control group （χ2＝4.057，P<0.05）. ConclusionOn the basis of the treatment with methotrexate tablets， Xinfeng capsules can effectively improve the immunoinflammatory level in RA due to spleen deficiency and dampness exuberance and reduce the incidence of adverse reactions.
ABSTRACT
Objective:To analyze locoregional recurrence (LRR) pattern of patients with pT 1-2N 1 breast cancer after modified radical mastectomy, with and without adjuvant radiotherapy (RT). Methods:A total of 5442 eligible patients with breast cancer from 12 Chinese centers were included. The LRR sites and the effect of RT at different sites on recurrence in patients with and without RT were analyzed. The Kaplan-Meier method was used to calculate the cumulative LRR rate, and the difference was compared by the log-rank test.Results:With a median follow-up time of 63.8 months for the entire cohort, 395 patients developed LRR. The chest wall and supraclavicular fossa were the most common LRR sites, regardless of RT or molecular subtypes. The 5-year chest wall recurrence rates for patients with and without chest wall irradiation were 2.5% and 3.8%( P=0.003); the 5-year supraclavicular lymph nodal recurrence rates for patients with and without supraclavicular fossa irradiation were 1.3% and 4.1%( P<0.001); the 5-year axillary recurrence-free rates for patients with and without axillary irradiation were 0.8% and 1.5%( HR=0.31, 95% CI: 0.04-2.23, P=0.219); and the 5-year internal mammary nodal recurrence-free rates for patients with and without internal mammary nodal irradiation were 0.8% and 1.5%( HR=0.45, 95% CI: 0.11-1.90, P=0.268). Conclusions:The chest wall and supraclavicular fossa are the most common LRR sites of patients with pT 1-2N 1 breast cancer after modified radical mastectomy, which is not affected by adjuvant RT or molecular subtypes. The chest wall and supraclavicular fossa irradiation significantly reduce the risk of recurrence in the corresponding area. However, axillary and internal mammary nodal irradiation has no impact on the risk of recurrence in the corresponding area.
ABSTRACT
Objective:To explore the expression of the nucleotide-binding oligomerization domain-like receptor containing pyrin domain protein 6 (NLR family,pyrin domain containing 6,NLRP6) in the gastric tissue and gastric juice of children with chronic non-atrophic gastritis (CNG), and to analyze the influence of Helicobacter pylori (Hp) infection on the expression of NLRP6.Methods:A case-control study was conducted to select 120 CNG patients in pediatrics of Department of Pediatrics, The Affiliated Hospital of Xuzhou Medical University from October 2020 to July 2021. According to pathological diagnosis, endoscopic gastric mucosal damage and Hp infection, they were divided into 4 groups: mild CNG group Hp negative, Moderate to severe CNG group Hp negative, Mild CNG group Hp positive, Moderate to severe CNG group Hp positive. The enzyme-linked immunosorbent assay (ELISA) was used to detect the expression level of NLRP6 in the four groups of gastric tissue and gastric juice, and Western blot was used to detect the expression of NLRP6 in the gastric tissue of the 4 groups, and the significance of expression in CNG of children is analyzed. Independent sample t-test was used to compare the mean between the two groups. One way ANOVA was used to compare the mean of multiple groups of samples, and LSD t-test was used for pairwise comparison. Comparison between count data groups χ 2 inspection. Results:The positive rate of Hp in the moderate to severe chronic non-atrophic gastritis group was 62.96% (34/54) higher than that in the mild chronic non-atrophic gastritis group 37.04% (20/54), and the difference was statistically significant (χ 2=18.32, P<0.001). Under the same Hp conditions, the expression of NLRP6 in the mild chronic non-atrophic gastritis group (Hp negative mild CNG: gastric tissue (653.73±37.71) ng/L, gastric juice (471.75±38.47) ng/L; Hp positive mild CNG: Gastric tissue (616.69±43.33) ng/L, gastric juice (445.29±36.39) ng/L was higher than the moderate to severe chronic non-atrophic gastritis group (Hp negative moderate to severe CNG: gastric tissue (623.82±52.99) ng/L, gastric juice (446.48±47.49) ng/L; Hp positive Moderate to severe CNG: gastric tissue (580.43±62.75) ng/L, gastric juice (406.88±51.85) ng/L, the difference is statistically significant (under Hp negative, mild compared with moderate to severe CNG: gastric tissue P=0.035; gastric juice P=0.046; Under Hp positive, mild compared with moderate to severe CNG: gastric tissue P=0.010;gastric juice P=0.002); in the same degree of gastric mucosal injury, NLRP6 expression in Hp-negative group (Hp-negative mild CNG: gastric tissue (653.73±37.71) ng/L, gastric juice (471.75±38.47) ng/L; Hp negative moderate to severe CNG: gastric tissue (623.82±52.99) ng/L, gastric juice (446.48±47.49) ng/L higher than the positive group (Hp positive mild CNG: gastric tissue (616.69±43.33) ng/L, gastric juice (445.29±36.39) ng/L; Hp positive moderate to severe CNG: gastric tissue (580.43±62.75) ng/L, gastric juice (406.88±51.85) ng/L, the difference is statistically significant (under mild CNG, Hp negative is compared with positive: Gastric tissue P=0.005; gastric juice P=0.023; under moderate to severe CNG, negative versus positive: gastric tissue P=0.004; gastric juice P=0.003). Conclusion:Under the same Hp conditions, the more severe the gastric mucosal damage, the lower the NLRP6; under the same degree of mucosal damage, the expression level of NLRP6 in the Hp-negative group was significantly higher than that of the Hp-positive group. It is suggested that NLRP6 plays a role in inhibiting inflammation in chronic gastritis, maintaining the integrity of epithelial cells, and Hp can inhibit the expression of NLRP6.

The potential medicinal value of Ma bamboo (Dendrocalamus latiflorus), one of the most popular and economically important bamboo species in China, has been underestimated. In the present study, we found that D. latiflorus leaf extract (DLE) reduced fasting blood glucose levels, body weight, and low-density lipoprotein cholesterol with low liver toxicity in db/db mice. In addition, gene expression profiling was performed and pathway enrichment analysis showed that DLE affected metabolic pathways. Importantly, DLE activated the AKT signaling pathway and reduced glucose production by downregulating glucose-6-phosphatase (G6PC) and phosphoenolpyruvate carboxykinase 1 (PCK1) expression. Moreover, network pharmacology analysis identified rutin as an active component in DLE through targeting insulin growth factor 1 receptor (IGF1R), an upstream signaling transducer of AKT. Due to its hypoglycemic effects and low toxicity, DLE may be considered an adjuvant treatment option for type 2 diabetes patients.
ABSTRACT
OBJECTIVE@#To investigate the clinical characteristics and risk factor analysis of necrotizing pneumonia in children.@*METHODS@#A retrospective study was used to analyze the case data of 218 children with severe pneumonia hospitalized in the Department of Respiratory Medicine, Children's Hospital of Capital Institute of Pediatrics from January 2016 to January 2020, and they were divided into 96 cases in the necrotizing pneumonia group (NP group) and 122 cases in the non-necrotizing pneumonia group (NNP group) according to whether necrosis of the lung occurred. The differences in clinical characteristics (malnutrition, fever duration, hospitalization time, imaging performance, treatment and regression follow-up), laboratory tests [leukocytes, neutrophil ratio, platelet (PLT), C-reactive protein (CRP), procalcitonin (PCT), D-dimer, and lactate dehydrogenase (LDH)] and bronchoscopic performance between the two groups were compared, and Logistic regression analysis of clinical risk factors associated with necrotizing pneumonia was performed to further determine the maximum diagnostic value of each index by subject operating characteristic curve (ROC). The critical value of each index was further determined by the ROC.@*RESULTS@#The differences in age, gender, pathogenic classification, and bronchoscopic presentation between the two groups of children were not statistically significant (P>0.05); whereas the imaging uptake time of the children in the NP group was higher than that in the NNP group (P < 0.05). The differences in malnutrition, fever duration, length of stay, white blood cell count, neutrophil ratio, CRP, PCT, and D-dimer were statistically significant between the two groups (P < 0.05). The imaging uptake time was lower in children under 6 years of age than in those over 6 years of age, and the imaging uptake time for bronchoalveolar lavage within 10 d of disease duration was lower than that for those over 10 d; the imaging uptake time was significantly longer in the mixed infection group than that in the single pathogen infection group. Logistic regression analysis of the two groups revealed that the duration of fever, hospital stay, CRP, PCT, and D-dimer were risk factors for secondary pulmonary necrosis (P < 0.001, P < 0.001, P < 0.001, P=0.013, P=0.001, respectively). The ROC curves for fever duration, CRP, PCT, and D-dimer were plotted and found to have diagnostic value for predicting the occurrence of pulmonary necrosis when fever duration >11.5 d, CRP >48.35 mg/L, and D-dimer > 4.25 mg/L [area under ROC curve (AUC)=0.909, 0.836, and 0.747, all P < 0.001].@*CONCLUSION@#Children with necrotizing pneumonia have a longer heat course and hospital stay, and the imaging uptake time of mixed pathogenic infections is significantly longer than that of single pathogenic infections. Children with necrotizing pneumonia under 6 years of age have more advantageous efficacy of electronic bronchoscopic alveolar lavage within 10 d of disease duration compared with children in the group over 6 years of age and children in the group with disease duration >10 d. Inflammatory indexes CRP, PCT, and D-dimer are significantly higher. The heat course, CRP, PCT, and D-dimer are risk factors for secondary lung necrosis in severe pneumonia. Heat course >11.5 d, CRP >48.35 mg/L, and D-dimer >4.25 mg/L have high predictive value for the diagnosis of necrotizing pneumonia.

Objectives: To summarize the clinical phenotypes and the variation spectrum of ATP7B gene in Chinese children with Wilson's disease (WD) and to investigate their significance for early diagnosis. Methods: Retrospective analysis was performed on the clinical data of 316 children diagnosed as WD in Guangzhou Women and Children's Medical Center during the period from January 2010 to June 2021. The general situations, clinical manifestations, lab test results, imaging examinations, and ATP7B gene variant characteristics were collected. The patients were divided into asymptomatic WD group and symptomatic WD group based on the presence or absence of clinical symptoms at the time that WD diagnosis was made. The χ2 test, t test or Mann-Whitney U test were used to compare the differences between groups. Results: Among the 316 children with WD, 199 were males and 117 were females, with the age of 5.4 (4.0, 7.6) years at diagnosis; 261 cases (82.6%) were asymptomatic with the age of 4.9 (3.9, 6.4) years; whereas 55 cases (17.4%) were symptomatic with the age of 9.6 (7.3, 12.0) years. The main symptoms invloved liver, kidney, nervous system, or skin damage. Of all the patients, 95.9% (303/316) had abnormal liver function at diagnosis; 98.1% (310/316) had the serum ceruloplasmin lever lower than 200 mg/L; 97.7% (302/309) had 24-hour urine copper content exceeding 40 μg; only 7.4% (23/310) had positive corneal K-F rings, 8.2% (23/281) had abnormal MRI signals in the lenticular nucleus, and all of them had symptoms of damage in liver, kidney or nervous system. Compared with the group of symptomatic WD, asymptomatic group had higher levels of serum alanine aminotransferase and lower levels ceruloplasmin and 24-hour urine copper [(208±137) vs. (72±78) U/L, (55±47) vs. (69±48) mg/L, 103 (72, 153) vs. 492 (230, 1 432) μg; t=9.98, -1.98, Z=-4.89, all P<0.001]. Among the 314 patients completing genetic sequencing, a total of 107 mutations in ATP7B gene were detected, of which 10 are novel variants, and 3 cases (1.0%) had large heterozygous deletion (exons 10 to exon 11) in ATP7B gene. The percentage of missense mutation in asymptomatic WD children was significantly higher than that in symptomatic WD (81.5% (422/518) vs. 69.1% (76/110), χ²=8.47, P<0.05). WD patients carrying homozygous variant of c.2 333G>T had significantly low levels of ceruloplasmin than those not carrying this variant ((23±5) vs. (61±48) mg/L, t=-2.34, P<0.001). Conclusions: The elevation of serum ALT is an important clue for early diagnosis of WD in children, while serum ceruloplasmin and 24-hour urine copper content are specific markers for early diagnosis of WD. In order to confirm the diagnosis of WD, it is necessary to combine the Sanger sequencing with multiplex ligation-dependent probe amplification or other testing technologies.

Objective:To analyze the change trend of survival rate after hip fragility fracture in Tianjin Hospital from 2015 to 2021, and the influence of gender, marital status, age and number of complications on survival rate.Methods:From January 1, 2015 to December 31, 2021, a total of 12,570 patients with fragility fracture of hip were retrieved, including 3,934 males and 8,636 females. The age at admission was 74.11±9.50 years and 74.62±8.99 years respectively. By comparing the ID number with the Tianjin population information database, 2,054 cases died, including 804 males and 1,250 females, aged 81.34±7.88 years and 81.92±7.42 years respectively at the time of death. Acquire the patient's survival status, calculate the cumulative survival rate at 3 month intervals, study the change rule of the cumulative survival rate over time, and use Kaplan-Meier method to calculate the cumulative survival rate of the whole population and the impact of gender, marital status, age, and number of complications on the survival rate.Results:The median survival time of all the dead people after fracture was 13(3, 31) months, including 11(2, 27) months for males and 15(4, 32) months for females. Joinpoint regression showed that 9 months after the hip fragility fracture was the break point of the survival rate. The mortality rate changed significantly within 9 months after fracture (the annual change rate was 47%), and slowed down 9 months later (the annual change rate was 1%). There was a statistically significant difference in trend detection before and after the break point ( P<0.05). The age at admission was 80.11±7.71 years for the dead and 73.36±9.01 years for the non dead, with a statistically significant difference ( t=31.80, P<0.001). After normalization, the number of complications was 0.20±0.93 among the dead and 0.00±0.87 among the non dead, with a statistically significant difference ( t=88.81, P<0.001). The survival rate of men after hip fracture is lower than that of women, the number of people without spouse is lower than that of people with spouse, the number of people with more than 70 years old is lower than that of people with less than 70 years old, and the number of complications ≥2 people is lower than that of people with less than 1 complication, all of which are statistically significant ( P<0.05). Conclusion:The survival rate within 9 months after the occurrence of hip fragility fracture decreased significantly, and it needs to be tracked and managed for at least 9 months to effectively reduce the risk of death; Male, no spouse, age>70 years old, number of complications ≥2 will increase the risk of death after hip fragility fracture, leading to reduced survival rate of patients.
ABSTRACT
Aging is the process spontaneously occurred in living organisms. Cardiac fibrosis is a pathophysiological process of cardiac aging. Mangiferin is a wellknown C-glucoside xanthone in mango leaves with lots of beneficial properties. In this study, rat model of cardiac fibrosis was induced by injected with 150 mg/kg/d Dgalactose for 8 weeks. The age-related cardiac decline was estimated by detecting the relative weight of heart, the serum levels of cardiac injury indicators and the expression of hypertrophic biomakers. Cardiac oxidative stress and local inflammation were measured by detecting the levels of malondialdehyde, enzymatic antioxidant status and proinflammatory cytokines. Cardiac fibrosis was evaluated by observing collagen deposition via masson and sirius red staining, as well as by examining the expression of extracellular matrix proteins via Western blot analysis. The cardiac activity of profibrotic TGF-β1/p38/MK2 signaling pathway was assessed by measuring the expression of TGF-β1 and the phosphorylation levels of p38 and MK2. It was observed that mangiferin ameliorated D-galactose-induced cardiac aging, attenuated cardiac oxidative stress, inflammation and fibrosis, as well as inhibited the activation of TGF-β1/p38/MK2 signaling pathway. These results showed that mangiferin could ameliorate cardiac fibrosis in D-galactose-induced aging rats possibly via inhibiting TGF-β/p38/MK2 signaling pathway.
ABSTRACT
OBJECTIVE@#To assess the association of polymorphisms of receptor of advanced glycation end products (RAGE) gene, monocyte to high-density lipoprotein cholesterol ratio (MHR) and variability of heart rate among patients with coronary heart disease (CHD).@*METHODS@#120 patients with CHD and 120 healthy individuals were respectively selected as the observation group and the control group. Allelic and genotypic differences of -429T>C, 1704G>T, 82G>S, MHR ratio and heart rate variability between the two groups and patients with different severity were analyzed. The correlation between their genotypes and MHR ratio and heart rate variability was analyzed.@*RESULTS@#The 82G>S polymorphism of the RAGE gene and the allelic difference between the two groups and patients with different severity were statistically significant (P< 0.05). Compared with the control group and patients with mild to moderate phenotype, monocyte, total cholesterol, triglyceride, low density lipoprotein, MHR, low frequency in the observation group and patients with severe symptoms were significantly higher, while their high density lipoprotein, standard deviation of NN intervals (SDNN), standard deviation average of NN intervals (SDANN), root mean square successive differences, percentage of differences exceeding 50ms between adjacent normal number of intervals (PMN50), high frequency (HF) were significantly lower. The gene frequencies of G-Gly-T, T-Gly-T, G-Ser-T and G-Gly-C were correlated with SDNN, SDANN, rMSSD, PMN50, HF and MHR, but negatively correlated with low frequency.@*CONCLUSION@#Polymorphisms of the RAGE gene in patients with coronary heart disease are associated with the MHR ratio and heart rate variability, which can be used as markers for the diagnosis and efficacy evaluation.

OBJECTIVE@#To explore the influencing factors of perioperative blood transfusion in the treatment of elderly femoral intertrochanteric fractures with proximal femoral nail antirotation(PFNA).@*METHODS@#The clinical data of 109 elderly patients with intertrochanteric fractures who received PFNA treatment from July 2018 to January 2020 were retrospectively analyzed. Both pelvic hip X-rays and CT plain scans were performed before surgery. All patients were diagnosed by X-ray and CT plain scan of pelvis and hip before operation. Through the statistical analysis of the basic data of patients before and during operation, the risk factors of perioperative blood transfusion were explored.@*RESULTS@#Logistic regression analysis showed that age (@*CONCLUSION@#Age, fracture type, diabetes history, and preoperative hemoglobin are independent risk factors for perioperative blood transfusion in the treatment of elderly intertrochanteric fractures with PFNA. The older the patient, the history of diabetes, the more unstable the fracture, and the lower preoperative hemoglobin, the more likely it is to require a blood transfusion, which may provide a reference for clinical perioperative blood transfusion decisions.

Epilepsy is a brain condition characterized by the recurrence of unprovoked seizures. Recent studies have shown that complement component 3 (C3) aggravate the neuronal injury in epilepsy. And our previous studies revealed that TRPV1 (transient receptor potential vanilloid type 1) is involved in epilepsy. Whether complement C3 regulation of neuronal injury is related to the activation of TRPV1 during epilepsy is not fully understood. We found that in a mouse model of status epilepticus (SE), complement C3 derived from astrocytes was increased and aggravated neuronal injury, and that TRPV1-knockout rescued neurons from the injury induced by complement C3. Circular RNAs are abundant in the brain, and the reduction of circRad52 caused by complement C3 promoted the expression of TRPV1 and exacerbated neuronal injury. Mechanistically, disorders of neuron-glia interaction mediated by the C3-TRPV1 signaling pathway may be important for the induction of neuronal injury. This study provides support for the hypothesis that the C3-TRPV1 pathway is involved in the prevention and treatment of neuronal injury and cognitive disorders.

OBJECTIVE@#To investigate the effect of femoral offset (FO) on the postoperative functional results of proximal femoral nail antirotation (PFNA) in femoral trochanteric fractures.@*METHODS@#From May 2017 to June 2019, 112 patients receiving PFNA were analyzed, X-ray and CT examination of both hips were performed before operation, and X-ray examination of both hips of pelvis was performed on the first day after operation. Among them, 71 patients showed bilateral FO difference≤ 5 mm on positive X-ray film (group A), and 41 patients showed bilateral FO difference>5 mm (group B). There was no significant difference between two groups in gender, age, operative side, course of disease, Harris score of preoperative hip joint, preoperativeFO(@*RESULTS@#Patients in both groups were followed up for 12 months after surgery, and all patients reached the healing criteria. The difference of Harris score of the hip joint at 6 and 12 months after surgery was statistically significant (@*CONCLUSION@#In the treatment of trochanteric fractures with PFNA, the greater the difference of FO between the two sides, the worse the postoperative function of the patients. The appropriate FO(the difference of FO between the two sides ≤5 mm) can improve the postoperative function of the patients.

Colchicine plays an important role in the treatment of gout and some other diseases. Besides gastrointestinal symptoms, myopathy has been reported as a rare side effect of colchicine in some patients. We report a case of myopathy in a patient with chronic kidney disease caused by high-dose colchicine, and then review literature on colchicine-induced myopathy, so as to provide some experience for the clinical diagnosis, treatment and medication safety. A 51-year-old male patient with 10 years of gout and 5 years of chronic kidney disease history and irregular treatment was admitted to the hospital with complaint of recurrent left wrist arthralgia and emerging lower extremities myalgia after intake of 40-50 mg colchicine in total within 20 days. Laboratory examinations showed significantly increased creatine kinase (CK) and then colchicine-induced myopathy was diagnosed preliminarily. After withdrawl of colchicine and implementation of hydration, alkalization and intramuscular injection of compound betamethasone, the symptoms of arthralgia and myalgia were relieved within 3 days and CK decreased to normal range gradually. According to literature reports, colchicine related myopathy was mostly characterized by proximal myasthenia and myalgia, accompanied by elevated CK level, which usually occurred days to weeks after initial administration of colchicine at the usual dosage in patients with renal impairment or a change in the underlying disease state in those receiving long-term therapy, and the features might remit within three to four weeks after the drug was discontinued. Electromyography of proximal muscles showed myopathy marked by abnormal spontaneous activity and muscle pathology waa marked by accumulation of lysosomes and autophagic vacuoles. Chronic kidney disease, liver cirrhosis, higher colchicine dose and concomitant cytochrome P450 3A4 (CYP3A4) inhibitors were associated with increased risk of myo-pathy. Based on the similar efficacy and lower adverse reaction rate compared with larger dosage, small dose of colchicine was recommended by many important current guidelines and recommendations in the treatment of gout. In consideration of potential risks, colchicine should be used with caution in patients with kidney or liver impairment, and in those taking CYP3A4 or P-glycoprotein inhibitors. For those patients, the drug dose should be adjusted and the latent adverse reactions should be monitored carefully.

OBJECTIVE@#To explore the minimally invasive surgical method for cervical1-2 epidural neurilemmoma.@*METHODS@#The clinical features, imaging characteristics and surgical methods of 63 cases of cervical1-2 epidural neurilemmoma from July 2010 to December 2018 were reviewed and analyzed. Pain and numbness in occipitocervical region were the common clinical symptoms. There were 58 cases with pain, 30 cases with numbness, 3 cases with limb weakness and 2 cases with asymptomatic mass. Magnetic resonance imaging (MRI) showed that the tumors located in the cervical1-2 epidural space with diameter of 1-3 cm. The equal or slightly lower T1 and equal or slightly higher T2 signals were found on MRI. The tumors had obvious enhancement. Individualized laminotomy was performed according to the location and size of the tumors, and axis spinous processes were preserved as far as possible. Resection of tumor was performed strictly within the capsule.@*RESULTS@#Total and subtotal resection of tumor were achieved in 60 and 3 cases respectively, and no vertebral artery injury was found. The operation time ranged from 60 to 180 minutes, with an average of 92.83 minutes. The hospitalization time ranged from 3 to 9 days, with an average of 5.97 days. All tumors were confirmed as neurilemmoma by pathology. There was no postoperative infection or cerebrospinal fluid leakage. There was no new-onset dysfunction except 9 cases of numbness in the nerve innervation area. The period of follow-up ranged from 6 months to 8 years (median: 3 years). All the new-onset dysfunction recovered completely. Pain disappeared in all of the 58 patients with pain. Numbness recovered completely in 27 patients while slight numbness remained in another 3 patients. Three patients with muscle weakness recovered completely. The spinal function of all the patients restored to McCormick grade Ⅰ. No recurrence was found on MRI. No cervical spine instability or deformity was found on X-rays.@*CONCLUSION@#It is feasible to resect cervical1-2 epidural neurilemmoma by full use of the anatomical space between atlas and axis and individual laminotomy. It is helpful to prevent cervical instability or deformity by minimizing the destruction of cervical2 bone and preserving normal muscle attachment to cervical2 spinous process. Strict intracapsular resection can effectively prevent vertebral artery injury.

OBJECTIVE：To know about the co gnition level and self-medication behavior of antibiotics among urban and rural residents in Lu ’an city of Anhui province ，and to investigate its influential factors and to provide reference for promoting rational use of antibiotics. METHODS ：Totally 684 urban and rural residents aged 18-80 years in Lu ’an city were randomly selected as the research objects by stage sampling method. A self-designed questionnaire was used for household survey ，involving general demographic characteristics ，antibiotics related cognitive level ，antibiotics use behavior and related influential factors ，etc. RESULTS：A total of 657 questionnaires were collected ，with effective rate of 96.1％. Among them ，305 were from urban residents and 352 from rural residents. Among the 657 respondents，38.2％ were male and 61.8％ were female ；their age was （50.30±13.26）years old ；44.7％ of them were educated in primary school or below. 7.8％ of the respondents correctly recognized that antibiotics were not effective to the virus ；12.6％ knew antibiotic resistance ；55.1％ thought that frequent use of antibiotics would reduce the sensitivity of bacteria to it ；23.1％ said they knew the difference between prescription drugs and over-the-counter drugs；58.0％ could tell at least one case of not using antibiotics. For 7 knowledge items ，75.3％ of the residents in the survey area had a total score of less than 3；the cognition level of antibiotics was higher in urban areas and people with higher education level. 66.5％ of the respondents had used antibiotics in the past one year，of which 61.0％ obtained antibiotics by prescription 65161220。E-mail： from doctors ，50.7％ purchased antibiotics by themselves in pharmacies， and 13.1％ used the above two ways both. Among the people who have used antibiotics in the past year ， 81.9％ said they could buy antibiotics without prescription. Among the 657 respondents，49.0％ said that they had to obtain prescription from doctor when taking antibiotics ；68.9％ said that they would stop taking antibiotics when their symptoms improved；19.3％ would increase their dosage in order to enhance the curative effect ；28.3％ would change drugs frequently. Compared with urban residents ，rural residents were more likely to take antibiotics based on prescriptions by physicians [odds ratio （OR）＝1.693，95％ confidence interval （CI）（1.191，2.407）]. The higher the cognitive score ，the lower the behavior rate of having to prescribe antibiotics by doctors [OR ＝0.882，95％CI（0.785，0.991）]，and they were more likely to stop taking antibiotics when symptoms improved [OR ＝1.163，95％CI（1.025，1.319）]，and male were more inclined to increase the dosage of antibiotics to enhance the efficacy [OR ＝1.841，95％CI（1.214，2.792）]. The higher the cognitive score was ，the less likely they were to increase drug dosage to enhance the curative effect [OR ＝0.894，95％CI（0.773，1.034）]，nor were they inclined to change drugs frequently [OR ＝0.873，95％CI（0.767，0.992）]. CONCLUSIONS ：The cognition level to antibiotics of urban and rural residents in Lu ’an city needs to be improved urgently ，and reasonable antibiotic use behavior needs to be standardized. Pure knowledge of antibiotics is not necessarily related to the expected rational drug use behavior. Therefore ，in addition to health promotion for the rational use of drugs for residents ，it is also necessary to create a systematic environment that promotes the rational use of antibiotics and provide residents with multi-channel services for rational use of drugs.
ABSTRACT
Compressed sensing (CS) has been investigated in magnetic resonance (MR) parametric mapping to reduce scan time. However, the relatively long reconstruction time restricts its widespread applications in the clinic. Recently, deep learningbased methods have shown great potential in accelerating reconstruction time and improving imaging quality in fast MR imaging, although their adaptation to parametric mapping is still in an early stage. In this paper, we proposed a novel deep learningbased framework DEMO for fast and robust MR parametric mapping. Different from current deep learning-based methods, DEMO trains the network in an unsupervised way, which is more practical given that it is difficult to acquire large fully sampled training data of parametric-weighted images. Specifically, a CS-based loss function is used in DEMO to avoid the necessity of using fully sampled k-space data as the label, thus making it an unsupervised learning approach. DEMO reconstructs parametric weighted images and generates a parametric map simultaneously by unrolling an interaction approach in conventional fast MR parametric mapping, which enables multi-tasking learning. Experimental results showed promising performance of the proposed DEMO framework in quantitative MR T1ρ mapping.
ABSTRACT
Objective:To identify the risk factors for postoperative central nervous system complications (CNSC) developed in pediatric patients undergoing cardiac surgery under cardiopulmonary bypass (CPB) through determining regional cerebral oxygen saturation (rSO 2C) by near-infrared spectroscopy. Methods:A total of 60 pediatric patients with congenital heart disease undergoing elective orthodontic correction surgery under CPB, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, of both sexes, aged 6-36 months, weighing 5-19 kg, in our hospital from July 2019 to January 2020 were collected.Intraoperative bilateral rSO 2C was monitored continuously by near-infrared spectroscopy.Blood samples were taken from the central vein at 10 min after induction of anesthesia, immediately after CPB, at the end of CPB, on admission to ICU, at 4 and 8 h after entering ICU and at 1, 2 and 3 days after surgery (T 0-8) for determination of the concentrations of serum S100β protein and neuron specific enolase (NSE). At 12 months after surgery, the Pediatric Cerebral Performance Category (PCPC) score was used to evaluate the prognosis of neurological function.The patients were divided into 2 groups according to whether CNSC occurred: CNSC group and non-CNSC group.Multivariate logistic regression analysis was used to identify the risk factors for development of postoperative CNSC in pediatric patients undergoing cardiac surgery under CPB. Results:Two patients were excluded from the study.Eighteen cases developed postoperative CNSC, and the incidence was 31.0%.Compared with group non-CNSC, the minimal rSO 2 was significantly decreased, the maximal difference between pulse oxygen saturation and rSO 2C (da-rSO 2C) was increased, duration of reduction in rSO 2>25% during CPB, duration of rSO 2C<40% during CPB and duration of da-rSO 2C>50% during CPB were prolonged, and concentrations of serum S100β protein and NSE were increased at T 2-T 8 in group CNSC ( P<0.05). The results of logistic regression analysis showed that prolonged duration of reduction in rSO 2C>25% during CPB, prolonged duration of rSO 2C<40% during CPB and prolonged duration of da-rSO 2C>50% during CPB were risk factors for development of postoperative CNSC. Conclusion:Prolonged duration of reduction in rSO 2C>25% during CPB, prolonged duration of rSO 2C<40% during CPB and prolonged duration of da-rSO 2C>50% during CPB are the risk factors for postoperative CNCS developed.
ABSTRACT
Galangal (Alpinia officinaruim Hance) is the rhizome of the perennial herb belonging to Zingiberaceae family. There are many active components in galangal, such as volatile oil, flavonoids, terpenoids, phenylpropanoids and glycosides, among which the content of volatile oil is higher. The bioactivities of galangal volatile oil on health effect includesanti-inflammatory, anti-hypertension, anti-oxidation and prevention of cardiovascular diseases. Cardiovascular disease (CVD) is a kind of diseases related to circulatory system, which is also called circulatory system diseases. Over the past decade, the number of people dying from CVD has increased by 12.5％ worldwide, and it is now the leading cause of human death worldwide. Studies have shown that galangal volatile oil has good pharmacological effects in treating CVD. ① Regulation of glucose and lipid metabolism: studies have found that abnormal lipid metabolism can lead to obesity, diabetes, CVD and other diseases. The serum total triglyceride (TG) content in liver and serum will increase in patients with abnormal fat metabolism. The results showed that the volatile oil of galangal could increase the excretion of neutral cholesterol, significantly reduce liver TG and serum TG, and thus regulate glucose and lipid metabo?lism, prevent lipid deposition and prevent CVD. ② Improving insulin resistance (IR): inhibition of inflammatory cytokines such as IL-1, IL-6 activation and expression of TNF-α, improves IR, thereby protecting myocardium from IR-mediated damage. Through the establishment of endothelial cell injury model induced by high glucose in vitro, it was found that the volatile oil of galangal can significantly reduce the secretion of pro-inflammatory cytokines TNF-αand IL-8, and inhib?it the expression of ICAM-1 and VCAM-1 induced by high glucose, suggesting that it has protective effect on endothelial dysfunction and inflammation induced by high glucose.③Regulate blood oxygenation:during acute myocardial hypoxia, the activity of free radical scavenging system is decreased, and oxygen free radicals are produced in large quantity, which reacts with unsaturated fatty acids on the cell membrane and forms lipid peroxidation, resulting in myocardial structural damage. The results showed that the water extract of Galangal could reduce the content of MDA in blood and protect the SOD activity of ischemic and hypoxic myocardium.④ Protective effect of vascular endothelial cells (ES):ES injury is the pathological basis of some cardiovascular diseases. The results showed that the volatile oil of galangal had a protective effect on ES apoptosis. Compared with the morphology and activity of ES treated with oxidized LDL, galan?gal volatile oil could ameliorate these morphological changes and improve cell viability. ⑤ Antiplatelet agglutination:inhibit platelet aggregation and thromboxane release, improve blood circulation, and have obvious anti-thrombotic effect, which has a good effect on the treatment and prevention of cardiovascular diseases. The results showed that the volatile oil of galangal had inhibitory effect on platelet aggregation and anticoagulant effect. In conclusion, the volatile oil of galangal can be used to prevent and treat cardiovascular diseases. Based on the mechanism of CVD, this study summa?rized the role of the essential oil of Alpinia officinaruim in CVD, providing basis for the clinical application of alpiniaoffici?nalis essential oil in the prevention and treatment of CVD and the development of new drugs.
