RESUMEN
Objective To evaluate the predictive value of serum carbohydrate antigen 50(CA50),tumor specific growth factor(TSGF),and tissue polypeptide antigen(TPA)levels for sensitivity to radiochemotherapy in patients with middle-and advanced-stage breast cancer using a nomogram model.Methods Eighty-two patients with middle-and advanced-stage breast cancer were selected as the study sub-jects.All patients received paclitaxel chemotherapy combined with radiotherapy and were divided into sensitive(n= 57)and insensitive(n= 25)groups according to the Response Evaluation Criteria in Solid Tumors.The general information of the patients,serum expression of CA50,TSGF,and TPA,and their differences before and after treatment were recorded.A nomogram model was constructed,and cali-bration curves,receiver operating characteristic(ROC)curves,and decision curves were used to evaluate the predictive power and clinical utility of the nomogram model.Results Significant differences were observed in tumor diameter,vascular invasion,TNM stage,lymph node metastasis,and degree of differentiation between the two groups(P<0.05).Compared to those in the sensitive group,the serum expression of CA50,TSGF,and TPA after treatment was higher,and the difference in CA50,TSGF,and TPA was smaller in the insensitive group(P<0.05).Three predictive variables were identified in the LASSO regression:differences in CA50,TSGF,and TPA.The logistic regression results showed that differences in CA50,TSGF,and TPA influenced sensitivity to radiochemotherapy in middle-and advanced-stage breast cancer(P<0.05).A nomogram model was constructed using differences in CA50,TSGF,and TPA.Calibration,ROC,and decision curves showed the model's good predictive accuracy and clinical utility.Conclusion Serum expression of CA50,TSGF,and TPA is high in patients with middle-and advanced-stage breast cancer who are insensitive to radiochemotherapy,and differences in CA50,TSGF,and TPA affect their sensitivity to radiochemotherapy.The nomogram model had good predictive value and clinical utility.
RESUMEN
Steroids are a class of medicines with important physiological and pharmacological effects. In pharmaceutical industry, steroidal intermediates are mainly prepared through Mycobacteria transformation, and then modified chemically or enzymatically into advanced steroidal compounds. Compared with the "diosgenin-dienolone" route, Mycobacteria transformation has the advantages of abundant raw materials, cost-effective, short reaction route, high yield and environmental friendliness. Based on genomics and metabolomics, the key enzymes in the phytosterol degradation pathway of Mycobacteria and their catalytic mechanisms are further revealed, which makes it possible for Mycobacteria to be used as chassis cells. This review summarizes the progress in the discovery of steroid-converting enzymes from different species, the modification of Mycobacteria genes and the overexpression of heterologous genes, and the optimization and modification of Mycobacteria as chassis cells.

Mycobacterium neoaurum has the ability to produce steroidal intermediates known as 22-hydroxy-23, 24-bisnorchol-4-en-3-one (BA) upon the knockout of the genes for either the hydroxyacyl-CoA dehydrogenase (Hsd4A) or acyl-CoA thiolase (FadA5). In a previous study, we discovered a novel metabolite in the fermentation products when the fadA5 gene was deleted. This research aims to elucidate the metabolic pathway of this metabolite through structural identification, homologous sequence analysis of the fadA5 gene, phylogenetic tree analysis of M. neoaurum HGMS2, and gene knockout. Our findings revealed that the metabolite is a C23 metabolic intermediate, named 24-norchol-4-ene-3, 22-dione (designated as 3-OPD). It is formed when a thioesterase (TE) catalyzes the formation of a β-ketonic acid by removing CoA from the side chain of 3, 22-dioxo-25, 26-bisnorchol-4-ene-24-oyl CoA (22-O-BNC-CoA), followed by spontaneously undergoing decarboxylation. These results have the potential to contribute to the development of novel steroid intermediates.

Niemann-Pick disease type C is a lipid storage disorder associated with impaired intracellular cholesterol trafficking, caused by mutations of either NPC1 or NPC2 genes.According to the age at onset of symptoms, it is divided into 5 categories, including neonatal, early-infantile, late-infantile, juvenile and adult type.There are differences in clinical manifestations and prognoses among each category.The characteristic clinical manifestations are hepatosplenomegaly, lung infiltration, vertical supranuclear gaze palsy and gelastic cataplexy.The definite diagnosis requires demonstration of unesterified cholesterol accumulated in fibroblasts cultured from skin biopsies with filipin staining and(or) of pathogenic mutation of NPC1/NPC2 genes.There is no effective treatment for this disease yet, therefore the overall prognosis is still poor.Miglustat can delay onset of the neurological symptoms, and prolong survival of partial patients.
RESUMEN
Objective:A case of cystic fibrosis admitted in the Respiratory Department of Beijing Children′s Hospital, Capital Medical University in June 2018 and underwent lung transplantation later was analyzed retrospectively.A 10-year-old girl had intermittent productive cough for more than 4 years with clubbed-finger.The lung high resolution CT (HRCT) showed bronchiectasis and mucus impaction, and the nasal sinus HRCT showed sinusitis.She had cystic fibrosis transmembrane conductance regulator ( CFTR) gene complex heterozygous mutation and positive sweat test.The immunoglobulin E (IgE) level and eosinophil count increased, and aspergillus fumigatus-specific IgE was positive.She was diagnosed as cystic fibrosis, allergic bronchopulmonary aspergillosis and sinusitis.Anti-infection, glucocorticoid and symptomatic treatment were given.During the following 21 months, the child had repeated respiratory difficulties and respiratory failure.Her lung function declined.Bilateral lung transplantation was performed in March 2020.She had a good recovery at more than 1 year and 3 months postoperatively.
RESUMEN
Objective:To explore the clinical efficacy of periosteum-covered iliac crest autografts for treatment of severe osteochondral lesions of talus (OCLTs).Methods:A retrospective case series study was used to analyze the clinical data of 26 patients with severe OCLTs treated at Zhejiang Armed Police Corps Hospital from January 2013 to October 2019. There were 21 males and 5 females,aged 17-49 years [(36.3 ± 10.9)years]. All patients were treated using periosteum-covered iliac crest autografts. The visual analogue scale (VAS),American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and ankle joint range of motion (ROM) were assessed before operation,6 months after operation and at the last follow-up (≥ 12 months). The area of talus injury with MRI at the same level was recorded before operation and at the last follow-up. The healing of talus and joint surface was detected with CT at the last follow-up. The healing of the incision and osteotomy site and complications were observed.Results:All patients were followed for 12 to 22 months[(15.1 ± 3.2)months]. The VAS was (2.4 ± 0.9)points and (1.7 ± 0.6)points at postoperative 6 months and at the last follow-up,significantly lower than the preoperative (5.4 ± 1.2)points ( P < 0.01). Meanwhile,the VAS at the last follow-up was significantly lower than that at postoperative 6 months ( P < 0.01). The AOFAS ankle-hindfoot score was (71.7 ± 7.8)points and (87.8 ± 6.2) points at postoperative 6 months and at the last follow-up,significantly lower than the preoperative (66.5 ± 7.5) points ( P < 0.01). Meanwhile,the AOFAS ankle-hindfoot at the last follow-up was significantly lower than that at postoperative 6 months ( P < 0.01). The ankle ROM was (58.4 ± 5.5)° and (70.0 ± 4.9)° at postoperative 6 months and at the last follow-up,significantly improved when compared to the preoperative (42.3 ± 8.1)° ( P < 0.01). Meanwhile,the ankle ROM at the last follow-up was significantly improved when compared to that at postoperative 6 months ( P < 0.01). The area of talus injury with MRI at the same level was 0.67(0.55,0.89)cm 2 at the last follow-up,significantly improved when compared to preoperative 2.64(1.98,3.68)cm 2 ( P < 0.01). The transplantation had neither obvious defects nor joint surface steps based on CT findings. All surgical incisions were healed by first intention. There were no complications such as incision infection,skin necrosis,nonunion of osteotomy,malunion or severe ankle joint disorder except that 8 patients had residual local subchondral bone?marrow?edema-like?signal?and 2 patients showed delayed healing of medial malleolus osteotomy. Conclusion:For patients with severe OCLTs,periosteum-covered iliac crest autografts can effectively relieve ankle pain,improve ankle function,and reduce the area of injury.
RESUMEN
Objective:To summarize the clinical features of children with autosomal dominant hyper-IgE syndrome (AD-HIES) and the differential diagnosis of hyper-IgE syndrome and allergic diseases as well.Methods:All clinical data, including general information, clinical features, and genetic changes, from 7 children with AD-HIES who were diagnosed in Beijing Children′s Hospital Affiliated to Capital Medical University from April 2016 to June 2020 were analyzed retrospectively.The diagnostic criteria are based on the National Institutes of Health′s (NIH)′s hyper-IgE syndrome score and combined with the results of gene detection, shown as follows: (1) NIH score over 40, with signal transducer and activator of transcription 3 gene ( STAT3) pathogenic mutation; (2) NIH score between 20 and 40, with reported STAT3 pathogenic mutation; (3) NIH score less than 20 points was excluded. Results:There were 3 males and 4 females.The onset age of 7 cases was within 2 months after birth, and the mean age at diagnosis was 3 years old.All seven cases had recurrent skin or lung infections, with 4 cases having skin and lung infections, 1 case of skin abscesses at the BCG vaccination site, and 2 cases without skin infection suffering from recurrent pneumonia.The mean onset age of skin abscess in 5 cases was 1.5 years, and pus culture of 3 cases were Staphylococcus aureus.Four cases developed bullae and 6 cases had lung infections.Four cases had otitis media, and oral thrush was seen in 4 cases.One case of skin and lung infection developed liver abscess and sepsis.Seven cases had eczema, which was disco-vered in the neonatal period for 6 cases.Four cases had the symptoms of eczema for the first visit.Two cases had food allergy, and 1 case had recurrent wheezing within 1 year old.The serum IgE level and blood eosinophil count in 7 children were elevated.All children had heterozygous pathogenic mutations in STAT3.Six patients had de novo mutations.There were 6 different mutation sites.The 4 mutation sites were reported: c.1145G>A, c.1144C>T, and c. 1699A>G were missense mutations, and c. 1139+ 5G>A was splicing mutation.Two mutation sites had not been reported: c.1031A>C was missense mutation, and c. 2050G>T was nonsense mutation.The pathogenic grade of them were likely pathogenic, and the NIH score of 2 cases were above 40 score, which was consistent with the clinical diagnosis of hyper-IgE syndrome. Conclusions:Eczema is a common and early clinical manifestation of hyper-IgE syndrome, along with elevated IgE levels and eosinophil counts that need to be differentiated from allergic diseases.On the contrary, it often had recurrent skin abscesses or pneumonia, which was prone to bullae.The clinical manifestations of young children were atypical, and genetic testing was helpful for early diagnosis.
RESUMEN
Nylon 6,6 composite fiber containing grafted graphene (nylon 6,6-g-graphene) was prepared by nylon and graphene grafted with acyl chloride (graphene-COCl) through extrusion reaction. Graphene-COCl was prepared through acid-treated reacting, graphene with thionyl chloride functional group. The chemical structure of nylon 6,6-g-graphene obtained using reactive extrusion technique was characterized using Fourier transform infrared spectrometer. It was found that this kind of composite fiber has the characteristics of less amount of graphene and excellent mechanical properties and has certain application prospects. Nylon 6,6-g-graphene dispersed evenly in the Nylon composite. But pristine graphene exhibited aggregate structure when composite was produced by pristine graphene through reactive extrusion. The composite reinforcement was increased obviously with the increase content of grafted graphene. After examined, the nylon/nylon 6,6-g-graphene with a certain content grafted graphene composite exhibited high level of reinforcement, and mechanical properties were improved.

RESUMEN
Primary immunodeficiency diseases (PIDs) refer to immune function decrease and deficiency or immune regulation function imbalance resulted from immune cell or immunomolecular defects caused by single gene mutation.Children with PIDs are prone to develop infectious diseases.Because the immune mechanisms of hosts infected by different pathogens infecting vary, different types of PIDs are relatively susceptible to different pathogens.A number of studies have indicated that some PIDs children are more likely to develop Bacilles Calmétte-Guerin infection, severe tuberculosis and non- Tuberculous mycobacteria severe infection.In this review, several major primary immunodeficiency diseases closely related to the susceptibility of mycobacteria were summarized, including chronic granulomatous disease, severe combined immunodeficiency disease, mendelian susceptibility to mycobacterial disease, and high IgM syndrome, in order to provide a theoretical basis for early identification of such diseases.
RESUMEN
To analyze respectively a case,presented with recurrent petechial and epistaxis after a 2 years history of diabetes mellitus (DM),who was hospitalized in Beijing Children's Hospital Affiliated to Capital Medical University.The clinical manifestation,examination,diagnosis and treatment were recorded.The patient was diagnosed with immune thrombocytopenia (ITP) and DM at the first admission.The initial therapy with gamma globulin didn't show ideal effect.The pediatric specialists from the department of ENT,Hematology/Oncology,Endocrinology,Pharmacy and Immunodeficiency Clinic were invited to discuss the case.The final diagnosis of autoimmune polyglandular syndrome (APS) was made and supplementary steroid treatment was started.But the response of the steroid therapy was poor.Once again with the multidisciplinary consultation,the patient received several schemes of Rituximab under the informed consent.This treatment reached a stable condition for almost 7 years.APS should be considered when DM patient showed the manifestation of other immune organ damages.Rituximab immunosuppressive therapy should be tried when the response to first-line treatment was poor.

Objective To analyze the clinical characteristics of community-acquired influenza virus pneumonia in hospitalized children and improve the clinicians' understanding level of this disease.Methods Data of 70 cases with community-acquired influenza virus pneumonia admitted to the Respiratory Department and Infectious Disease,Beijing Children's Hospital,Capital Medical University,from November 2009 to April 2018 were collected and the clinical characteristics were analyzed.Results Of the 70 cases,61 cases(89.7%) were discharged after improvement.The median age was 3.5 years old,and 50 cases(71.4%) were 0 to 5 years old.There were 29 cases with severe influenza pneumonia,41 cases with mild influenza pneumonia,3 cases died,and 19 cases (27.1%) had underlying diseases.Sixty-four cases (91.4%) were hospitalized in winter and spring.The first symptoms were mainly fever in 64 cases (91.4%) and cough in 65 cases (92.9%),and temperatures were mostly from 39.1 ℃ to 41.0 ℃.Lung auscultation was dominated by moist rales (30 cases,58.8%) and wheezing (8 cases,15.7%).There were many complications of influenza virus pneumonia,including 19 cases with myocardial injury,11 cases with liver function injury,4 cases with toxic encephalopathy,3 cases with electrolyte disturbance,2 cases with multiple organ failure,2 cases with hemophagocytic syndrome,and 1 case with septic shock.Chest radiographic results reveal bilateral inflammation in 40 children (57.1%),prodominatly in lower lobe lesions (39 cases).The common changes were patchy shadow,interstitial parenchymal lesion,ground glass shadow,and pleural effusion.Forty-seven children (67.1%) were infected by influenza A,and 23 children(32.9%) were co-infected.The percentage of severe cases with underlying diseases (68.4%) was significantly higher than that in children without chronic diseases (31.4%),the difference was statistically significant (x2 =7.830,P =0.005).The increase rate of C reaction protein (CRP) in severe cases (54.3%) was significantly higher than that in mild cases (28.6%),the difference was statistically significant (x2 =4.769,P =0.029).Conclusions Community-acquired influenza virus pneumonia in children mainly occurs in winter and spring.It is more common seen in children under 5 years of age.The main clinical manifestations of community-acquired influenza virus pneumonia are high fever and cough,extrapulmonary complications are more common.Most children have moist rales and showed bilateral inflammation and lower lobe lesions in chest radiography.Children with underlying diseases are more likely to develop severe influenza virus pneumonia.Elevated CRP is associated with severe influenza virus pneumonia.Most patients have a good prognosis,but there are still cases of death.
RESUMEN
Objective To explore the diagnosis and treatment of atypical severe combined immunodeficiency disease (SCID). Methods The clinical data of atypical SCID in 7 children with IL2RG,JAK3,and RAG1 mutations were reviewed and analyzed from September 2012 to June 2017. Results In 7 cases (6 males and 1 female), there were 5 infants, 1 toddler and 1 school-age child. Cases 2, 4, and 6 were classic SCID clinical phenotypes. Cases 1, 3, 5, 7 were atypical SCID clinical phenotypes. Case 6 were diagnosed with Omenn syndrome. Cases 2, 5 were classic SCID immune phenotypes, cases 1, 3, 4, 6, 7 were atypical SCID immune phenotypes, and case 1 had maternal chimera. The next generation sequencing indicated that case 1 had a compound heterozygous JAK3 mutation with c.3097-1G>A/c.946-950GCGGA>ACinsGGT.Cases 2,3,and 4 had IL2RG mutations,with c.865C>T/p.R289X,c.664C>T/R222C,52delG,respectively.Case 5 had JAK3 mutations with c.2150A>G/p.E717G and c.1915-2A>G.Sanger sequencing indicated that case 6 had a RAG1 mutation of complex heterozygosity with c.994C>T/p.R332X and c.1439G>A/p.S480N. Case 7 had homozygous RAG1 mutation with c.2095C>T/p.R699W.Conclusion Under certain conditions,gene mutation can lead to atypical clinical and/or immune phenotypic SCID.
RESUMEN
Combined immunodeficiency (CID) is categorized to the first classification from the international union of immunological societies expert committee for primary immunodeficiency.Severe combined immunodeficiency (SCID) is the most fatal disorder for paediatric clinical operation.Without hematopoietic stem cell transplantation,almost all infants would die before 1 year old,few could survive beyond 2 years old.Hypomorphic mutations in SCID genes can lead to atypical phenotypes.The two special SCID should be focused,Omenn syndrome and graft-versus-host disease,which are caused by expension of autologous and maternal activated and memory T lymphocytes,respectively.Patients with radiosensitive-CID usually present later on life,for whom treatment should be monitored carefully.CID caused by T cells with normal development and inborn error was hotspot research field for example zeta chain-associated protein 70 kDa deficiency.More attention should be paid to CID associated with syndromes for example dedicator of cytokinesis 8 deficiency.Now,the pathogenesis,molecular,clinical,laboratory features and treatment and prognosis are described,in order to support clues for paediatrician's clinical practice.
RESUMEN
Activated phosphoinositide 3-kinase δ (PIK3CD) syndrome is a combined immunodeficiency,caused by PIK3CD gain-of-function mutations,which encodes the catalytic subunit of PIK3CD.These patients presented with early onset sinopulmonary infections,lymphoproliferation,herpesvirus infections,autoinflammatory disease,lymphoma and mental retardation.Hyper immunoglobulin (Ig)M,IgG deficiency,CD4 lymphopenia were common immunologic features.Variable expression can lead to death and asymptom.Penetrance can be incomplete.Hematopoietie stem cell transplantation should be taken into account for severe cases.
RESUMEN
Mendelian susceptibility to mycobacterial diseases (MSMD)is a rare congenital disorder characterized by susceptibility to poorly virulent mycobacteria,such as Bacille Calmette-Guerin vaccine or non-tuberculous environmental mycobacteria.The interferon-γ'(IFN-γ)/interleukin-12 (IL-12) pathway is central to controlling mycobacterial infections,in which several genes had been identified.IFN-γ secretion is impaired in patients with IL-12p40 and IL-12 receptor β1 deficiency,where the response to IFN-γ is impaired in patients with IFN-γ receptor 1,IFN-γ receptor 2,and signal transducer and activator of transcription 1 deficiencies.Furthermore,germline mutations in the cytochrome b (-245) beta subunit,interferon regulatory factor 8,ubiquitin-like modifier,RORC and TYK2 have been identified as the genes which are responsible for MSMD.These patients do not generally have associated infections,apart from salmonellosis.Now,the pathogenesis,molecular,clinical,laboratory features,treatment and prognosis were described,in order to support the clues for pediatrician's clinical practice.
RESUMEN
Chronic mucocutaneous candidiasis (CMC) is characterized by persistent or recurrent disease of the nails,skin,oral,or genital mucosae caused by candida albicans.CMC usually can occur in patients with T cell deficiencies,autosomal dominant hyper-immunoglobulin E(IgE) syndrome,interleukin(IL)-12p40 and IL-12 receptor β1 (IL-12Rβ1) deficiency,caspase recruiment domain 9 deficiency and autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy.CMC pathogenesis apparently involves the impairment of IL-17A,IL-17F and IL-22 immunity.Autosomal recessive IL-17RA deficiency and dominant-negative IL-17F deficiency are etiologies of pure isolated CMC (CMCD).Nearly half of patients with CMC had gain-of-function signal transducer and activator of transcription 1 mutations.These patients also had bacterial and virus infections,autoimmunity and inflammatory diseases,which show broad clinical heterogenity.
RESUMEN
22q11.2 deletion syndrome is the commonest chromosome deletion syndrome.Most patients with DiGeorge anomaly have monosomic deletions of chromosome 22q11.2.Abnormal pharyngeal arch development results in defects in the development of the parathyroid glands,thymus and conotruncal region of the heart.Defective thymus development is associated with impaired immune function." Complete" DiGeorge syndrome accounts for < 0.5% of patients with total absence of the thymus and a severe T cell immunodeficiency.Most patients with partial defects have variable T cell deficiency.There is a wide phenotypic spectrum including speech delay,neuropsychiatric disorders and otolaryngological disorders.These patients are at increased risk of a variety of autoimmune diseases.Severe cases need thymus transplantation.
RESUMEN

RESUMEN
Objective To investigate the association of serum fibroblast growth factor 21(FGF-21)with coronary heart disease(CHD)and biochemical indexes. Methods Serum FGF-21 expression was detected by ELISA.310 healthy control subjects and 310 CHD patients were recruited.Basic information was obtained by clini-cal questionnaires. Venous blood was tested for serum lipid,fasting glucose,and C-reactive protein(CRP). All the data were analyzed with the SPSS 19.0. Results There were no significant differences in gender and age be-tween CHD and controls(P > 0.05). FGF-21 level was significantly higher in CHD patients than in the controls (P<0.05).Univariate analysis showed serum FGF-21 was a risk factor of CHD.The group of higher score for FGF-21 had a 5.20-fold risk of CHD than the group of lower score without adjustment for confounding factors(95% CI:4.23~8.42).After control of the confounding factors,the group of higher score had a 7.21-fold risk of CHD(95% CI:3.78~13.67)than the group of lower score,it remains the significant difference(P<0.05).Conclusion Ele-vation of serum FGF-21 was closely associated with initiation and development of CHD.
