RESUMEN
The traditional Chinese medicine (TCM) in pediatric care has a long history,proven efficacy,and distinctive characteristics.The China Association of Chinese Medicine has organized a series of youth salons to discuss the clinical advantages of treating diseases.Experts at this seminar proposed that the superior disease categories in pediatric TCM are significant for showcasing the unique strengths and advantages of TCM in the treatment of pediatric diseases,enhancing diagnostic and treatment levels,inheriting TCM knowledge,promoting the integration of TCM and Western medicine,and meeting patients' needs.The strengths of pediatric TCM are summed up as "having what others do not,excelling at what others have,being special in what others excel at,and ensuring safety in what others specialize in." The scope of superiority in pediatric TCM covers multiple systems,including respiratory,digestive,endocrine,psychological,and dermatological systems.This article summarized the advantages of TCM in treating 13 diseases discussed in the salon,such as upper respiratory tract infections,coughs,pneumonia,allergic rhinitis,bronchial asthma,atopic dermatitis,functional dyspepsia,functional constipation,enuresis,marginal short stature,simple obesity,attention deficit hyperactivity disorder,and tic disorders.The overall advantages were reflected in three aspects:First,the holistic concept and treatment based on syndrome differentiation in TCM highlight the advantage of treating the root causes of diseases,making the treatment methodical and precise.Second,most traditional Chinese herbs are natural and have strong safety profiles.Third,TCM treatment methods are abundant,especially the external treatment methods,which are widely used in pediatrics,highly accepted by parents,and have definite efficacy,as well as good safety and compliance.

RESUMEN
Sugar-sugar glycosyltransferases play important roles in constructing complex and bioactive saponins. Here, we characterized a series of UDP-glycosyltransferases responsible for biosynthesizing the branched sugar chain of bioactive steroidal saponins from a widely known medicinal plant Paris polyphylla var. yunnanensis. Among them, a 2'-O-rhamnosyltransferase and three 6'-O-glucosyltrasferases catalyzed a cascade of glycosylation to produce steroidal diglycosides and triglycosides, respectively. These UDP-glycosyltransferases showed astonishing substrate promiscuity, resulting in the generation of a panel of 24 terpenoid glycosides including 15 previously undescribed compounds. A mutant library containing 44 variants was constructed based on the identification of critical residues by molecular docking simulations and protein model alignments, and a mutant UGT91AH1Y187A with increased catalytic efficiency was obtained. The steroidal saponins exhibited remarkable antifungal activity against four widespread strains of human pathogenic fungi attributed to ergosterol-dependent damage of fungal cell membranes, and 2'-O-rhamnosylation appeared to correlate with strong antifungal effects. The findings elucidated the biosynthetic machinery for their production of steroidal saponins and revealed their potential as new antifungal agents.
RESUMEN
[Abstract] Objective To explore the role of purinergic ligand-gated ion chennel 7 receptor(P2X7R) in cognitive dysfunction in Parkinson’s disease rats. Methods Ninty rats was divided into 5 groups with 6 rats in each group with 3 repeats. The rat model of PD was established by 6-hydroxydopamine (6-OHDA). PD rats were injected with P2X7R agonists 2,3-adenosine 5-triethylammonium triphosphate (BzATP) and antagonists Comassie brilliant blue G (CBBG). The learning and memory ability and pain response of rats in the water maze were measured, and the expression of P2X7 in hippocampus was detected by Real-time PCR and Western blotting. Results Compared with the normal rats, PD rats had slow learning speed and weak memory ability. CBBG improved the learning and memory ability of PD rats, while BzATP decreased the learning and memory ability of PD rats. The result of Real-time PCR showed that compared with the control group, the expression of P2X7R mRNA was the highest in hippocampal tissue, the expression of P2X7R in CBBG group was down-regulated, and that of P2X7R in BzATP group was up-regulated. Compared with the PD group, Western blotting of P2X7R showed that the expression of P2X7 protein increased significantly in BzATP group, while the expression of P2X7 protein was lower in CBBG group. Conclusion Cognitive impairment exists in PD rats. CBBG can improve the learning and memory function of PD rats, and BzATP can inhibit the learning and memory function of PD rats.
RESUMEN
Objective:To analyze the clinical significance of multigene assay in papillary thyroid carcinoma(PTC). Methods:Patients who underwent thyroidectomy in a tertiary hospital from August 2021 to May 2022 were enrolled. The eight-gene panel was used to detect the tumor tissue of patients, and the correlation between gene mutations and clinical features was analyzed. Results:Among 161 patients, mutation rate of BRAF V600E, RET/PTC1 and TERT promotor were 82.0%, 6.8% and 4.3%, respectively. BRAF V600E mutation was more common in male patients(P=0.023). TERT promotor-mutated tumors had a large diameter(P=0.019), a high proportion of multifocal lesions(P=0.050), and a large number of lymph node metastases(P=0.031). Among 89 patients who completed preoperative BRAF detection, there was a strong consistency between the preoperative aspiration test and postoperative panel(Cohen κ=0.694, 95%CI: 0.482-0.906, P<0.01). In the hematoxylin-eosin sections obtained from 80 patients, BRAF V600E was still the main type of gene mutation, and the classical/follicular type was more distributed. TERT promotor and RET/PTC1 mutation were the main genetic events for tall-cell/columnar/hobnail type and diffuse sclerosing type, respectively. One-way ANOVA showed that there were differences in diagnosis age(P=0.029) and tumor size(P<0.01) among different pathological types. Conclusion:As a simple and feasible clinical detection method for PTC, the multigene assay can supplement the identification of important genetic events other than BRAF V600E, and provide more prognostic information and follow-up hints for postoperative patients.

RESUMEN
Objective:To screen the serum exosomal microRNAs differentially expressed in early pancreatic cancer patients and evaluate the diagnostic value of exosomal hsa-let-7f-5p.Methods:From January 2019 to January 2020, 19 patients with early pancreatic cancer (early pancreatic cancer group) and 16 patients with chronic mass-forming pancreatitis (pancreatitis group) were selected from Affiliated Hospital of Nanjing University of Chinese Medicine who underwent surgery and were confirmed by pathology. Serum samples of the two groups of patients were collected. At the same time, serum samples of 19 healthy volunteers were selected as the normal control group. The exoEasy Maxi Kit was used to isolate serum exosomes. The structural characteristics of exosomes were observed by transmission electron microscopy (TEM). The particle size of exosomes was observd by nanoparticle tracking analysis. CD 63 and CD 81, the specific protein marker on the surface of exosomes, were identified by western blotting. The total RNA of exosomes was extracted by the miRNeasy Serum/Plasma Kit, and a small RNA library was constructed after quality inspection. With reference to the small RNA database, the differentially expressed exosomal microRNAs in early pancreatic cancer group, pancreatitis group and normal control group were filtered out. The miRNA candidates were validated by quantitative polymerase chain reaction (qPCR) and different expressions of them were analyzed. The role of target genes and metabolic pathways of candidate miRNAs in the occurrence and development of early pancreatic cancer were analyzed by gene ontology (GO) and Kyoto Encyclopeda of Genes and Genomes(KEGG) enrichment pathway. Results:The isolated serum exosomes can be seen to have cup-like vesicle with the double lipid layer by TEM. The main peak of the particle size of target exosomes was about 150 nm. The expression of exosome specific protein markers CD 63 and CD 81 was positive. Comparing the expression of miRNAs among early pancreatic cancer group, pancreatitis group and normal control group, the specific tumor marker exosomal hsa-let-7f-5p was screened out in this study, and its expression in early pancreatic cancer group was significantly higher than that in pancreatitis group and normal control group (both P values <0.05). Receiver operating characteristic curve analysis (ROC) showed that the area under curve (AUC) of exosomal hsa-let-7f-5p to distinguish pancreatic cancer from pancreatitis was 0.843 (95% CI 0.640-1.000). The sensitivity and specificity were 100% and 81.82% respectively. The AUC for distinguishing pancreatic cancer from normal controls was 1.000 (95% CI 1.000-1.000), and both sensitivity and specificity were 100%. The diagnostic efficiency of exosomal hsa-let-7f-5p was equivalent to that of CA19-9 ( P>0.05). The GO analysis results showed that target genes of exosomal hsa-let-7f-5p were mainly involved in complement activation lectin pathway in biological processes, and the proteins expressed by target genes were mainly distributed in cilium, and molecules mostly functioned by combining with nitric-oxide synthase. The KEGG pathway enrichment analysis showed that the target genes were closely related to MAPK signaling pathway. Conclusions:Serum exosomal hsa-let-7f-5p has the potential to be a diagnostic biomarker for early pancreatic cancer.
RESUMEN
Objective: Patients with advanced gastric cancer have a poor prognosis and a possibility of peritoneal metastasis even if receiving gastrectomy. Hyperthermic intraperitoneal chemotherapy (HIPEC) can effectively kill free cancer cells or small lesions in the abdominal cavity. At present, preventive HIPEC still lacks safety evaluation in patients with locally advanced gastric cancer. This study aims to explore the safety of radical resection combined with HIPEC in patients with locally advanced gastric cancer. Methods: A descriptive case series study was carried out. Clinicopathological data of 130 patients with locally advanced gastric cancer who underwent radical resection + HIPEC at the Department of Gastrointestinal Surgery, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 2020 to February 2021 were retrospectively analyzed. Inclusion criteria: (1) locally advanced gastric adenocarcinoma confirmed by postoperative pathology; (2) no distant metastasis was found before surgery; (3) radical resection; (4) at least one HIPEC treatment was performed. Exclusion criteria: (1) incomplete clinicopathological data; (2) tumor metastasis was found during operation; (3) concomitant with other tumors. HIPEC method: all the patients received the first HIPEC immediately after D2 radical resection, and returned to the ward after waking up from anesthesia; the second and the third HIPEC were carried out according to the patient's postoperative recovery and tolerance; interval between two HIPEC treatments was 48 h. Observation indicators: (1) basic information, including gender, age, body mass index, etc.; (2) treatment status; (3) perioperative adverse events: based on the standard of common adverse events published by the US Department of Health and Public Health (CTCAE 5.0), the adverse events of grade 2 and above during the treatment period were recorded, including hypoalbuminemia, bone marrow cell reduction, wound complications, abdominal infection, lung infection, gastroparesis, anemia, postoperative bleeding, anastomotic leakage, intestinal obstruction, pleural effusion, abdominal distension, impaired liver function, and finally a senior professional title chief physician reviewed the above adverse events and made a safety evaluation of the patient; (4) association between times of HIPEC treatment and adverse events in perioperative period; (5) analysis of risk factors for adverse events in perioperative period. Results: Among the 130 patients, 79 were males and 51 were females with a median age of 59 (54, 66) years and an average body mass index of (23.9±7.4) kg/m(2). The tumor size was (5.4±3.0) cm and 100 patients (76.9%) had nerve invasion. All the 130 patients received radical resection + HIPEC and 125 (96.2%) patients underwent laparoscopic surgery. The mean operative time was (345.6±52.3) min and intraoperative blood loss was (82.0±36.5) ml. One HIPEC treatment was performed in 54 patients (41.5%), 2 HIPEC treatments were in 57 (43.8%), and 3 HIPEC treatments were in 19 (14.6%). The average postoperative hospital stay was (13.1±7.5) d. A total of 57 patients (43.8%) had 71 cases of postoperative complications of different degrees. Among them, the incidence of hypoalbuminemia was 22.3% (29/130), and the grade 2 and above anemia was 15.4% (20/130), lung infection was 3.8% (5/130), bone marrow cell suppression was 3.7% (4/130), abdominal cavity infection was 2.3% (3/130), and liver damage was 2.3% (3/130), wound complications was 1.5% (2/130), abdominal distension was 1.5% (2/130), anastomotic leakage was 0.8% (1/130), gastroparesis was 0.8% (1/130) and intestinal obstruction was 0.8% (1/130), etc. These adverse events were all improved by conservative treatments. There were no statistically significant differences in the incidence of adverse events during the perioperative period among patients undergoing 1, 2, and 3 times of HIPEC treatments (all P>0.05). Univariate and multivariate logistic analyses showed that age > 60 years (OR: 2.346, 95%CI: 1.069-5.150, P=0.034) and neurological invasion (OR: 2.992, 95%CI: 1.050-8.523, P=0.040) were independent risk factors for adverse events in locally advanced gastric cancer patients undergoing radical resection+HIPEC (both P<0.05). Conclusions: Radical surgery + HIPEC does not significantly increase the incidence of perioperative complications in patients with advanced gastric cancer. The age >60 years and nerve invasion are independent risk factors for adverse events in these patients.

Objective: To systematically evaluate the efficacy and safety of total neoadjuvant therapy (TNT) in the comprehensive treatment of locally advanced rectal cancer. Methods: Literatures were screened from PubMed, Embase, Web of Science, Cochrane Library, CBM, Wanfang Data, VIP and CNKI from the inception date to May 2021 to collect the randomized controlled clinical trials (RCTs) of TNT followed by total mesorectal excision (TME) versus neoadjuvant chemotherapy (nCRT) followed by TME in the treatment of locally advanced rectal cancer. The data of overall survival, disease-free survival, R0 radical resection rate, pathological complete response (pCR) rate, T downstaging rate, the incidence of adverse events ≥ grade III, including neutropenia, nausea and vomiting, diarrhea, radiation dermatitis and nervous system toxicity, and the morbidity of complications within postoperative 30 days of the two groups were extracted from the included literatures. Review Manager 5.3 software was utilized for statistical meta-analysis. Results: Nine RCTs were finally enrolled including 2430 patients. Meta-analysis results showed that compared with nCRT group, patients in TNT group had longer overall survival (HR=0.80, 95%CI: 0.65-0.97, P=0.03) and higher pCR rate (RR=1.73, 95%CI: 1.44-2.08, P<0.01) with significant differences. Besides, there were no significant differences between two groups in disease-free survival (HR=0.86, 95%CI:0.71-1.05, P=0.14), R0 radical resection rate (RR=1.02, 95%CI: 0.99-1.06, P=0.17) and T downstaging rate (RR=1.04, 95%CI: 0.89-1.22, P=0.58) between two groups. In terms of treatment safety, the incidence of adverse events ≥ grade III (RR=1.09, 95%CI: 0.70-1.70, P=0.70) and morbidity of complications within postoperative 30 days (RR=1.07, 95%CI: 0.97-1.18, P=0.19) did not significantly differ between two groups. Conclusions: In the treatment of locally advanced rectal cancer, TNT may bring more survival benefits than nCRT and does not increase the incidence of adverse events and postoperative complications. Therefore, TNT could be used as a recommended treatment for patients with locally advanced rectal cancer.

【Objective】 To evaluate the coagulation function of children with Kasabach-Merritt syndrome(KMS)by thromboelastography (TEG) and conventional coagulation tests (CCTs), and to explore the correlation and consistency of the 2 test methods. 【Methods】 A total of 49 children with KMS, submitted to our hospital from January 2016 to December 2020, were enrolled. The TEG, CCTs data and platelet count were analyzed to evaluate the coagulation function, and the superiority of the 2 test methods were compared by Spearman correlation and Kappa consistency analysis. 【Results】 TEG and CCTs showed that the coagulation reaction time(R) was normal, the counts and function of platelet and fibrinogen decreased, and the D-dimer increased. The coagulation complex index (CI) indicated that the whole coagulation function was low. There was no significant difference in coagulation by sex or age in KMS children. The correlation analysis of TEG and CCTs in the coagulation function of KMS children showed that R was correlated with prothrombin time (PT) and activated partial thromboplastin Time(APTT), respectively (P<0.01); Fib had weak correlation with clot formation time (k)(r2=0.33), but strongly correlated with α-angle and MA value(r2=0.7, 0.69), respectively (P<0.01). PLT was moderately correlated with MA(r2=0.49, P<0.05); D-dimer had no correlation with LY30. Comparision resu lts of the consistency of TEG and CCTs showed that FIB and MA had consistency ( kappa=1, P<0.01); None or weak consistency was noticed among other indicators, R with PT/APTT, the kappa was 0.18 and 0.19; Fib with K/α-Angle, the kappa was 0.28 and 0.34; D-dimer with LY30, the kappa was 0.01; PLT with MA, the kappa was 0.35. 【Conclusion】 The main manifestations in low coagulation function in children with KMS were mainly thrombocytopenia, lower fibrinogen, and increased fibrinogen degradation-products, and the coagulation factors were normal. Except for Fib and MA, the consistency of other indexes in the detection of coagulation function in children with KMS by TEG and CCT is weak. Some indexes are significantly correlated but others not. Therefore, the 2 test methods are irreplaceable and should be combined to reduce the risk of embolism and bleeding in children.
RESUMEN
Objective:To systematically evaluate the effects of elastic resistance exercise on patients with chronic obstructive pulmonary disease (COPD). Methods:Randomized clinical trials about elastic resistance exercise for chronic obstructive pulmonary disease were searched in the Cochrane Library, PubMed, Web of Science, CNKI, VIP, Wanfang Database and Chinese Biomedical Literature Database from inception to September, 2020. Finally, eleven literatures were included, including 9 in English and 2 in Chinese, with a total of 485 patients. The quality of the articles was evaluated using the Cochrane Library systematic review criteria and Physiotherapy Evidence Database Scale, and the data were analyzed with RevMan 5.2. The system review was registered on PROSPERO (CRD42020208659). Results:There was no significant difference in 6 Minute Walking Distance (6WMD) (MD = 1.19, 95%CI -7.02 to 9.39, P = 0.78), COPD Assessment Test (CAT) (MD = -0.43, 95%CI -2.42 to 1.57, P = 0.68) and the muscle strength (MD = 0.23, 95%CI -1.06 to 1.52, P = 0.73), with no high heterogeneity, between elastic resistance exercise group and the conventional resistance exercise group (such as weight training machine, weight training). There was no significant difference in 6MWD (MD = 18.30, 95%CI -8.92 to 45.52, P = 0.19) and CAT (MD = 0.59, 95%CI -3.78 to 2.60, P = 0.72) between the elastic resistance exercise group and the non-resistance exercise group, however, the heterogeneity between them was high. Conclusion:Elastic resistance exercise may be potentially alternative to conventional resistance training. However, the effects of elastic resistance exercise on exercise endurance, quality of life and lung function are still unclear.

RESUMEN
Objective:To explore the effect of Vancomycin on immune hemolysis and coagulation in children with non-Hodgkin′s lymphoma (NHL), thus providing the basis for the diagnosis and treatment of hemolytic anemia and coagulation dysfunction caused by Vancomycin, and guiding the rational use of drugs in children with NHL.Methods:From January 2018 to January 2019, 31 children with NHL treated with monotherapy of Vancomycin in Beijing Children′s Hospital, Capital Medical University were collected.Plasma samples within 1 week of Vancomycin medication were collected for detecting the anti-Vancomycin antibody by microcolumn gel method.The laboratory diagnostic and coagulation function indexes of hemolytic anemia before and after Vancomycin medication were analyzed using the paired sample t test. Results:Fourteen out of 31 children with NHL were positive for the anti-Vancomycin antibody, and among them, 10 cases had positive direct antiglobulin test (DAT). In NHL children with positive anti-Vancomycin antibody, their red blood cell count (RBC)[(2.75±0.07)×10 12/L vs.(3.18±0.07)×10 12/L], platelet count (PLT)[64.29±14.87)×10 9/L vs.(91.36±16.84)×10 9/L] and hematocrit (HCT)[(23.02±0.83)% vs.(29.19±1.98)%] were significantly reduced after Vancomycin medication than those before treatment (all P<0.01). On the contrary, total bilirubin (TB) [(51.96±15.52) μmol/L vs.(39.34±13.40) μmol/L], direct bilirubin (DB)[(31.30±13.98) μmol/L vs.(26.38±12.61) μmol/L], indirect bilirubin (IB)[(21.81±2.89) μmol/L vs.(13.75±1.63) μmol/L] and lactate dehydrogenase (LDH)[(208.6±16.85) U/L vs.(60.93±16.00) U/L] in them were significantly enhanced after Vancomycin medication than those before treatment (all P<0.05). Prothrombin time (PT)[(13.94±0.58) s vs.(11.66±0.30) s] and partial thromboplastin time (APTT)[(36.01±2.64) s vs.(28.09±0.98) s] were significantly prolonged in them after vancomycin medication than those before treatment (all P<0.01). A higher international normalized ratio (INR)(1.25±0.05 vs.1.05±0.02) was detected in NHL children with positive anti-Vancomycin antibody after medication ( P<0.000 1). In NHL children with negative anti-Vancomycin antibody, significantly higher PT (12.99±0.35) s vs.(11.82±0.27) s and INR (1.18±0.03 vs.1.07±0.03) were detected after Vancomycin medication (all P<0.000 1), while other indexes were similar before and after treatment. Conclusions:The anti-Vancomycin antibody may cause immune hemolysis and coagulation dysfunction in children with NHL.In order to prevent serious adverse events caused by drug antibodies, comprehensively clinical symptoms should be considered, drug antibodies and laboratory test results should be detected.
RESUMEN
Objective: To observe the clinical efficacy of tuina manipulations in treating different types of tic disorders (TD). Methods: Eligible TD patients were classified into three types, transient tic disorders (TTD), chronic multiple tic disorders (CMTD) and Tourette syndrome (TS), according to their disease duration and severity. The three types of children were treated with the same tuina manipulations. Changes in the Yale global tic severity scale (YGTSS) score, effective rate for tic, and cervical spine imaging examination results (including asymmetry of the lateral atlanto-dental interval, broadened anterior atlanto-dental interval, C2 spinous process deviation, occipito-atlanto-axial flexion/ extension instability) were observed after 1-month and 3-month treatments respectively. Results: The YGTSS score changed significantly after 1-month and 3-month treatments compared with that before treatment (both P<0.01); the effective rate for TD was 46.6% and 86.7% respectively after 1-month and 3-month treatments; there were significant differences comparing the effective rate for tic between different types of TD after 1-month and 3-month treatments (all P<0.05); comparing the effective rate for tic after 1-month treatment with that after 3-month treatment for the same type, the intra-group differences were statistically significant [TTD group (P<0.01), CMTD group (P<0.01), TS group (P<0.05)]; the abnormal parameter rates in neck imaging examination after 3-month treatment were significantly different from those before treatment (all P<0.01). Conclusion: Tuina manipulation is effective for TTD, CMTD and TS. It can correct the abnormal alterations of patients' cervical vertebrae, and its efficacy for TTD is most significant.

Objective To investigate the effect of Xinmailong injection on patients with heart failure after emergency PCI and its effect on cardiac function. Methods 80 patients with heart failure after PCI in our hospital from December2015 to December 2016 were enrolled. All patients were divided into Xinmailong treatment group and conventional treatment group according to the random number table method, with 40 cases in each group. After emergency PCI, both groups were given conventional anti-platelet aggregation therapy, oral statin lipid-lowering drugs, ACEI, β-receptor antagonists, nitrates, etc. The Xinmailong treatment group was given 0.9% sodium chloride injection 100 mL+Xinmailong injection 6 m L (ivgtt, 2 times/d). And the conventional treatment group was given 0.9% sodium chloride injection 100 mL (ivgtt, 2 times/day). The two groups were treated continuously for 4 weeks. The clinical efficacy after treatment, as well as the changes of serum NT-proBNP levels before and after 1 week and 1 month of treatment, the LVEF and LVEDd before and after treatment of the two groups. Results The total effective rate of the patients in Xinmailong treatment group was 95.00%, which was significantly higher than that of the conventional treatment group, and the difference was significant (P<0.05). After treatment, serum NT-proBNP levels in the Xinmailong treatment group were significantly lower than those in the conventional treatment group at 1 week and 1 month after treatment, respectively, and the difference was significant (P<0.05). After treatment, the LVEF of the Xinmailong treatment group was significantly higher than that of the conventional treatment group, and the LVEDd of the Xinmailong treatment group was significantly lower than that of the conventional treatment group, and the difference was significant (P<0.05). Conclusion Xinmailong injection on the basis of routine treatment has exact curative effect on patients with heart failure after emergency PCI, which can significantly improve the heart function and improve the prognosis of patients. It is worthy of clinical promotion and application.
RESUMEN
OBJECTIVE@#To evaluate the coagulation function of children with Henoch-Schönlein purpura (HSP) by thromboelastography (TEG) and conventional coagulation tests (CCTs), and to explore the correlation and consistency of the 2 test methods.@*METHODS@#A total of 468 children with HSP were selected from January 2017 to December 2017 in Beijing Children's Hospital, Capital Medical University. The TEG and CCTs data were analyzed to evaluate coagulation function of children with HSP, meanwhile, the coagulation results were analysed the superiority of the 2 test methods was compared by Pearson correlation and Kappa consistency analysis.@*RESULTS@#There were no clinically significant abnormalities practically in HSP children by TEG and CCTs analysis, except for D-dimer level was elevated (t=9.15, P<0.001). There were no significant changes for coagulation data from, sex comparison of HSP children (P>0.05 all), but the coagulation reaction time (R), blood clot formation time (K), α-Angle, CI value, fibrinogen, D-dimer and anti-thrombin III in HSP children with different age groups showed difference (P<0.05 all), and the blood in children aged 0-2 years old tended to be hypercoagulable. The TEG indexes demonstrated no significant difference in coagulation function of children with HSP each other (P>0.05). However, CCTs data showed that the blood in children with severe kidney involvement were hypercoagulable. Comparision results of the correlation and consistency of TEG and CCTs in detecting coagulation function of HSP children showed that R was weakly correlated with prothrombin time (PT), International Normalized Ratio (INR) and activated partial thromboplastin time (APTT). There were weak correlation between K, α-Angle and Fib (0.1<|r|<0.4 all). There was no obvious consistency between them each other (kappa<0.4 all).@*CONCLUSION@#The overall changes in coagulation function in children with HSP are not obvious, but the hyperfibrinolysis in hypercoagulable state may exists. Furthermore, younger age and severe kidney involvement may cause hypercoagulation in HSP children. The weakly correlation and consistency of TEG and CCTs in detecting coagulation function of HSP children are furtherly confirmation, and the 2 test methods may be irreplaceable.

Three new phenazine-type compounds, named phenazines SA-SC (1-3), together with four new natural products (4-7), were isolated from the fermentation broth of an earwig-associated Streptomyces sp. NA04227. The structures of these compounds were determined by extensive analyses of NMR, high resolution mass spectroscopic data, as well as single-crystal X-ray diffraction measurement. Sequencing and analysis of the genome data allowed us to identify the gene cluster (spz) and propose a biosynthetic pathway for these phenazine-type compounds. Additionally, compounds 1-5 exhibited moderate inhibitory activity against acetylcholinesterase (AChE), and compound 3 showed antimicrobial activities against Micrococcus luteus.
