RESUMO
Helicobacter pylori(HP)infection is a Class Ⅰ carcinogen in gastric cancer,closely related to the occurrence of gastric cancer.Many studies have shown that HP eradication has a preventive effect on gastric cancer.However,2.7%-6.1%of patients with early gastric cancer who have been eradicated after endoscopic submucosal dissection(ESD)can still develop metachronous gastric cancer(MGC),and the mechanism of its occurrence is still unclear.In this review,the atrophy of gastric mucosa and intestinal metaplasia cannot be completely reversed after HP eradication,the excessive proliferation of gastric mucosa epithelial cells,the accumulation of genetic abnormalities,the homeostasis imbalance of the epigenetic group,changes in immune microenvironment,the abnormality of stem cells in gastric mucosa,chromatin accessibility,and changes in chromosome remodeling were discussed in the mechanism of carcinogenesis caused by the above molecular changes after ESD and HP eradication in early gastric cancer.
RESUMO
Objective To explore the therapeutic effect of traditional Chinese medicine (TCM) on subsolid nodule (SSN). Methods A practical randomized controlled study method, including 254 SSN patients was adopted. The patients were divided into the TCM (102 cases) and follow-up (152 cases) groups. The follow-up group received regular check-ups in accordance with the guidelines, and the TCM group received TCM syndrome differentiation treatment for 24 weeks. The two groups were compared in terms of the changes in their SSN diameter, SSN number, TCM symptom score, and overall therapeutic effect before and after treatment. Adverse reactions and safety indicators were also recorded. Results The TCM group showed a significantly higher effective rate of treatment (16.7%) than the follow-up group (2.6%) (P<0.01). Compared with their condition before treatment, the TCM group showed no significant changes in their SSN diameter and number but presented considerably reduced fatigue, yellow and red urine symptoms, and overall TCM symptom score (P<0.05). The follow-up group exhibited significantly increased diameter and number of SSN (P<0.01). The follow-up group showed the significantly higher increase in SSN diameter after treatment than the TCM group (P<0.05). Moreover, the follow-up group showed significantly higher fatigue, depression, yellow and red urine symptom scores, and overall TCM symptom score than the TCM group (P<0.05 or P<0.01). Conclusion TCM treatment for SSN has a distinct clinical efficacy, reduces the malignant risk of SSN and improves clinical symptoms of SSN patients, and is safe and feasible.
RESUMO
【Objective】 To identify the influencing factors of infant motor development, and to explore the potential interactive factors, so as to provide scientific basis for early prediction and targeted prevention of infant motor developmental delay. 【Methods】 Data of infants receiving "0~1 motor development screening" at 21 community health service centers in Tongzhou District, from January 1st, 2020 to August 31st, 2021 were collected through the Beijing Maternal and Child Information System.Using the method of nested case-control study, 416 infants with positive screening results were selected as case group, 416 infants with negative screening result were selected into the control group by 1∶1 case-control matching of screening age.Chi-square test, Logistic regression analysis, and Exhaustive CHAID decision tree model were used to explore the influencing factors of infant motor development, the interaction effect was investigated by using the additive and multiplicative interaction models. 【Results】 Multivariate Logistic analysis showed that birth weight<2 500g (OR=3.28), cesarean section (OR=1.63), outdoor activity≤ 1h/d (OR=3.07), and no supplementation of vitamin D (OR=2.68) were risk factors for positive screening results of infant motor development (P<0.01).The Exhaustive CHAID decision tree showed that low birth weight was the primary risk factor for infant with positive screening results, followed by outdoor activity, vitamin D supplementation and delivery.The interaction analysis showed that there was a multiplicative interaction (OR=13.76, 95% CI:1.20 - 158.08) and an additive interaction (RERI=10.22, 95%CI:5.05 - 15.38) between non supplementation of vitamin D and low birth weight on infant motor development with positive screening results. 【Conclusions】 Attention should be paid to the early motor development of infants with low birth weight and those born by cesarean section, with emphasis on the dosage of vitamin D supplementation and outdoor activity duration.Moreover, the early screening and hierarchical management of infant motor development should also be strengthened.

RESUMO
ObjectiveTo explore the importance of post-vaccination serological testing (PVST) for children exposed to hepatitis B virus (HBV), and analyze the factors affecting the progress of PVST. MethodsThe study focused on hepatitis B surface antigen (HBsAg)-positive pregnant women and their newborns residing in Tongzhou District, Beijing, who delivered at various obstetric institutions from January 1, 2020 to March 31, 2022. The obstetric institutions and community health service centers conducted follow-up visits 1 to 2 months after the children had received three doses of the hepatitis B vaccine (HepB). ResultsThe vaccination rate of hepatitis B immunoglobulin (HBIg) was 100.00% (800/800), with a successful PVST follow-up rate of 85.88% (687/800) in Tongzhou District. The initial non-response rate to immunization was 0.29% (2/687), but successful immunization was achieved after re-immunization. The mother-to-infant transmission rate of hepatitis B was 0. Children who did not undergo PVST accounted for 14.13% (113/800), with the main reasons being delays due to the COVID-19 pandemic, parents’ reluctance to allow venous blood collection due to the young age of the children, and loss to follow-up because children moved back to their parents’ place of origin. Logistic regression analysis showed that the proportion of PVST was higher among high-risk children (OR=30.009,P=0.001), children with family residing in Beijing (OR=2.218,P=0.002), and children whose mothers were <35 years old (OR=1.687,P=0.020). ConclusionPVST is necessary for assessing the status of HBV immune response in newborns after vaccination with HepB. The COVID-19 pandemic impacted the implementation of PVST for children exposed to HBV. Strengthening the management of non-high-risk children, those living outside Beijing, and children with mothers aged ≥ 35 years old may increase the rate of PVST in Tongzhou District.
RESUMO
ObjectiveTo investigate the difference of ultrasound characteristics between pure mucinous carcinoma (PMC) and fibroadenoma (FA) of the breast. MethodsUltrasound data of 50 continuous patients with breast PMC from January 2012 to January 2021 and 100 continuous patients with breast FA from June 2018 to January 2019 in Sun Yat-sen Memorial Hospital of Sun Yat-sen University were retrospectively reviewed. The ultrasound characteristics of the two groups were evaluated according to the 2013 BI-RADS Ultrasound Atlas, and the differences in age, maximum diameter and ultrasound characteristics between the two groups were compared. ResultsThe median age of PMC patients was 47 years and that of FA patients was 33 years. The age of PMC patients was higher than that of the FA group, and the difference between the two groups of patients was statistically significant (P<0.001). The median maximum diameter of PMC patients was 2.4 cm, which was greater than that of the FA group (1.8 cm), and the difference was statistically significant (P=0.001). Of the PMC, 70% (35/50) were irregular, 82% (41/50) were parallel to the skin, 92% (46/50) had no circumscribed margin, 72% (36/50) were hypoechoic, and 68% (34/50) had enhanced posterior echo. Of the FA, 69% (69/100) were oval or round, 98% (98/100) were parallel to the skin, 54% (54/100) had circumscribed margin, 98% (98/100) were hypoechoic, and 75% (75/100) had no posterior features. The differences in the above ultrasound characteristics between the PMC and FA groups were statistically significant (P<0.001, P=0.001, P<0.001, P<0.001, P<0.001). There was no significant difference between calcifications and blood flow. ConclusionsCompared with the FA group, patients with PMC are older and the diameter of the lesions are larger. On ultrasound, the morphology and margin of most breast PMC still show the growth characteristics of invasive cancer. Meanwhile, the posterior echo of PMC is enhanced, which is a unique manifestation.
RESUMO
Objective:To discuss the distinctive sonographic feature and the biological behavior of renal angiomyolipoma(RAML),and to provide the reference for the clinicians to make the accurate diagnosis of RAML.Methods:The clinical data of one patient with invasive classical RAML combined with pseudaneurysm formation were collected.The sonographic appearances were analyzed in conjunction with the pathological characteristics to clarify the biological behavior of RAML,and the relevant literatures were reviewed.Results:The patient,a 60-year-old female,visited the local hospital due to discomfort in the lumbar area,and received CT examination,and the CT examination results revealed a left renal mass,so the patient came to our hospital.The specialist clinical examinations and laboratory investigations were unremarkable.The ultrasound results indicated an enlarged left kidney with a cystic and solid mass at the upper pole,which featured pseudaneurysm formation(originating from the interlobar arteries);the enhanced CT image results suggested a high probability of upper pole renal carcinoma combined with aneurysmal formation within the tumor,alongside invasion into the left adrenal gland.The patient underwent laparoscopic radical left nephrectomy,and the postoperative pathology confirmed the diagnosis of invasive classical RAML.Conclusion:The classical RAML can exhibit the invasive biological behavior.The pseudaneurysm formation is a special sonographic manifestation of RAML,which can be challenging to differentiate from the other renal tumors.
RESUMO
The correct pairing of disulfide bonds maintains the correct folding mode and high-level structure formation of peptides and protein drugs, which is crucial for the quality control of products. In order to ensure that the disulfide bonds are correctly paired, disulfide bond analysis is an essential part of peptides and protein drug characterization. Mass spectrometry can be used to analyze disulfide bonds. However, insulin and its analogues have two pairs of disulfide bonds without restriction enzyme cutting site. Conventional collision-induced dissociation (CID) and high-energy induced cleavage (HCD) cannot accurately locate the complex disulfide bond. In our study, three methods were used to localize the complex disulfide, including enzyme digestion combined with key peptide fragment in source decay (ISD) fragmentation method, enzyme digestion combined with partial reduction alkylation method, intact protein source ISD and electron transfer dissociation (ETD) cleavage method, The applicability of insulin aspart, insulin lispro and insulin glargine were also investigated. This study provides a new way for the quality control of disulfide bonding mode of insulin and its analogues, and also provides a reference for the disulfide bond localization of peptides or proteins containing this complex disulfide bond.
RESUMO
Objective: The study investigated the clinical distribution, antimicrobial resistance and epidemiologic characteristics of hypervirulent Carbapenem-resistant Klebsiella pneumoniae (hv-CRKP) in a hospital in Henan Province to provide a scientific basis for antibiotic use and nosocomial infection prevention and control. Methods: A retrospective analysis of the clinical data from the cases was carried out in this study. Clinical data of patients infected with the CRKP strain isolated from the clinical microbiology laboratory of Henan Provincial Hospital of Traditional Chinese Medicine from January 2020 to December 2022 were retrospectively analyzed. A string test, virulence gene screening, serum killing, and a G. mellonella infection model were used to screen hv-CRKP isolates. The clinical characteristics of hv-CRKP and the drug resistance rate of hv-CRKP to twenty-five antibiotics were analyzed using WHONET 5.6. Carbapenemase phenotypic characterization of the hv-CRKP was performed by colloidal gold immunochromatographic assay, and Carbapenemase genotyping, multi-locus sequence typing (MLST) and capsular serotyping of hv-CRKP isolates were performed by PCR and Sanger sequencing. Results: A total of non-duplicate 264 CRKP clinical isolates were detected in the hospital from 2020 to 2022, and 23 hv-CRKP isolates were detected, so the corresponding detection rate of hv-CRKP was 8.71% (23/264). The hv-CRKP isolates in this study were mainly from the intensive care unit (10/23) and neurosurgery department (8/23), and the main sources of hv-CRKP isolates were sputum (10/23) and bronchoalveolar lavage fluid (6/23). The hv-CRKP isolates in this study were highly resistant to β-lactam antibiotics, fluoroquinolones and aminoglycosides, and were only susceptible to colistin, tigecycline and ceftazidime/avibactam. The detection rate of the blaKPC-2 among 23 hv-CRKP isolates was 91.30% (21/23) and none of the class B and class D carbapenemases were detected. Results of MLST and capsular serotypes showed that ST11 type hv-CRKP was the dominant strain in the hospital, accounting for 56.52% (13/23), and K64 (9/13) and KL47 (4/13) were the major capsular serotypes. Conclusion: The hv-CRKP isolates from the hospital are mainly from lower respiratory tract specimens from patients admitted to the intensive care department and the drug resistance is relatively severe. The predominant strains with certain polymorphisms are mainly composed of the KPC-2-producing ST11-K64 and ST11-KL47 hv-CRKP isolates in the hospital.

Objective: To understand the current situation of vaccination services for adults in China, explore how to establish a stable and efficient vaccination service system for adults, and provide reference for formulating corresponding policies. Methods: The vaccination information systems of nine provinces in China were used to obtain information on urban and rural vaccination of influenza vaccine, 23-valent pneumococcal polysaccharide vaccine (PPV23), and human papillomavirus vaccine (HPV) from 2019 to 2021. The indicator, vaccination rate/full vaccination rate, was used for statistical description. Results: The vaccination rate/full vaccination rate of the three vaccines in eastern China was generally higher than that in central and western China. The vaccination rate/full vaccination rate in urban areas was generally higher than that in rural areas. From 2019 to 2021, the vaccination rates of influenza vaccine among people aged 60 years and above in urban and rural areas were 2.96%, 6.29%, 6.14% and 1.29%, 2.58%, 2.94%, respectively. The vaccination rates of the PPV23 among people aged 60 years and above in urban and rural areas increased year by year, with rates of 0.38%, 1.05%, 1.15% and 0.14%, 0.49%, 0.59%, respectively. From 2019 to 2021, the HPV coverage of female adults aged 27-45 years in urban and rural areas increased year by year, with rates of 0.46%, 0.93%, 1.88% and 0.17%, 0.40%, 1.08%, respectively. Conclusion: The vaccination rates of influenza vaccine,PPV23 vaccine and HPV vaccine for adults in China are relatively low, with higher rates in the eastern region than in the central and western regions, and higher rates in urban areas than in rural areas. It is recommended to formulate corresponding health and economic policies and explore a suitable vaccination service system for adults in China to improve vaccination rates.

Objective To investigate the expression of differential genes in testicular tissue of patients with obstructive and non-ob-structive azoospermia by bioinformatics,and provide new markers for the diagnosis of non-obstructive azoospermia(NOA).Methods The microarray data of azoospermia related genes(GSE45885 and GSE9210)were downloaded from the gene expression comprehensive database(GEO)and analyzed online by GEO2R,and the NOA related differentially expressed genes(DEGs)were obtained.The common DEGs were determined by using Wayne's intersection.GO annotation and KEGG enrichment analysis of DEGs were carried out by using R software.The DEGs-related protein interaction network(PPI)was constructed with STRING.Then,the most significant Hub gene of NOA was screened out by Cytoscape software and visualization was performed.The diagnostic value of Hub gene for NOA was estimated by the receiver operating characteristics(ROC)curve and verified in GSE145467 data set.Results A total of 83 DEGs were obtained,of which 78 were down-regulated and 5 were up-regulated.GO enrichment analysis showed that DEGs was involved in biological processes(BP),including the development and differentiation of sperm cells,development of germ cells,assembly of motor cilia,etc.Cell composition(CC)mainly included sperm flagella,motor cilia,acrosome vesicles,spermatogenic nuclei,etc.Molecular function(MF)mainly included structural components,protein binding,heat shock protein binding and so on,which endowed com-pressive strength for extracellular matrix.KEGG-related pathways were involved in longevity regulation pathways,cell cycle and apopto-sis,and meiosis of oocytes in multiple species.The five Hub genes closely related to NOA,including SPAG5,CCNB2,AURKC,NCAPH and PTTG1,were screened by PPI network.The ROC curve showed that all the five Hub genes were potential genetic markers of NOA.Conclusion SPAG5,CCNB2,AURKC,NCAPH and PTTG1 genes may play the key role in the development of NOA and may be used as the new biomarkers for NOA.
RESUMO
Pediatric anti N-methyl-D-aspartate receptor(NMDAR)encephalitis is an autoimmune encephalitis.Its psychiatric symptoms are age-related, with the incidence increasing as the child grows older.Agitation and catatonia are prominent characteristic symptoms.For the treatment of agitation symptoms in children, medication is the preferred option.When medication proves ineffective, physical restraint can be considered.Effective management of agitation not only helps control symptoms but also motivates patients to comply with immunotherapy.Psychomotor agitation is a core symptom of catatonia, but our clinical understanding of catatonia in children is still limited, and there is a lack of consensus on treatment approaches.Electroconvulsive therapy has been proven to be an effective treatment modality.Children under 12 years may experience impaired adaptive functioning compared to adolescents and adults, which could lead to residual psychiatric symptoms.Therefore, summarizing the psychiatric symptoms, clinical management and prognosis of pediatric anti NMDAR encephalitis can improve early recognition of the condition and standardize the long-term management of psychiatric symptoms in affected children, thus enhancing prognosis.
RESUMO
ObjectiveTo describe the neuropsychological development screening of 0‒2 years in Tongzhou from 2017 to 2021 so as to understand the status and trend of developmental delay (DD). MethodsAnnual report data of 21 community health service centers in Tongzhou District from 2017 to 2021 were clustered, Chi square test was used to analyze the differences in positive rate and DD rate of children aged 0‒2 years with different ages and household registration, and Chi square trend test was used to analyze the linear trend of each age group and household registration. The Gesell test results in 762 children with developmental delay were analyzed, and Chi square test was used to compare the age distribution differences in gross motor, fine motor, language and personal-social behaviors. ResultsThe DD rate of children aged 0‒2 years in 2017‒2021 was 0.43%. A decreasing trend of DD rate in the 0‒ age group was observed (χ2=14.135, P<0.001), while an increasing trend of DD rate in the 1‒ and <3 age groups was observed (χ2=5.375, P=0.020; χ2=5.558, P=0.018). The DD rate of children aged 0‒2 years with Beijing household registration was higher (χ2=12.504, P<0.001). The DD rate of gross motor was the highest in the 0‒ age group (64.60%), the DD rate of language was the highest in the <3 age group (85.97%), and a statistically significant difference of gross motor and language was separately found in the three age groups (χ2=183.061, P<0.001; χ2=78.450, P<0.001). ConclusionAge and Beijing household registration are the influencing factors of DD for children aged 0‒2, and 0‒ years and <3 years are the critical periods for guidance and intervention to promote the development of gross motor and language abilities.
RESUMO
Objective:To analyze the experiences and practice in the reform of public hospital salary system in Sichuan province, summarize the typical modes of such reform in the province, and provide references for further reform.Methods:As of October 29, 2021, the research group received 77 sets of typical experience materials submitted by the health commissions and public hospitals in Sichuan province on enforcing the reform of the public hospital salary system. The analysis framework was based on the five main elements proposed in the Guidance to Deepening the Reform of the Salary System of Public Hospitals for the purpose of furthering the reform. These five elements refer to " reasonably determining the level of salary in public hospitals" " fully implementing the autonomy of internal distribution in public hospitals " " establishing and improving the incentive and restraint mechanism for the remuneration of public hospital leaders" " improving the assessment and evaluation mechanism oriented to public welfare" and " funding sources ". A quantitative analysis was made on the typical experience materials using the social network analysis method, while a qualitative analysis was made on the typical experience materials using the content analysis method. Results:The results of social network analysis showed that the network density was 0.272; the highest point centrality was " fully implement the autonomy of internal distribution in public hospitals" (0.935), and the highest intermediary centrality was " improving the assessment and evaluation mechanism oriented to public welfare" (0.870), while the closeness to centrality of " establishing and improving the incentive and constraint mechanism for the salary of public hospital leaders" (0.434) and " funding sources" (0.421) were relatively low. The results of content analysis showed that the ones with higher frequency among all the typical experience materials were " fully implementing the autonomy of internal distribution of hospitals" (72 times) and " improving the assessment and evaluation mechanism oriented to public welfare" (67 times), while the ones with lower frequency were " establishing and improving the salary incentive and constraint mechanism for public hospital leaders" (17 times) and " funding sources" (14 times). In terms of unity and synergy, the typical models of public hospital salary system reform in the province could be categorized as the fine standard mode, the fair value mode, the autonomous synergy mode and the circular symbiosis mode.Conclusions:Deepening the reform of the salary system of public hospitals should unify the standards and improve the fair and refined assessment and evaluation mechanism; explore various forms of distribution and build an internal autonomous and synergistic incentive mechanism; pay attention to the weak remuneration incentive mechanism for hospital leaders and the problem of a relatively single source of funding.
RESUMO
Objective:To investigate the value of SHOX2 and RASSF1A gene promoter region methylation detection for screening and diagnosis of early-stage lung adenocarcinoma.Methods:The mRNA sequencing data of 471 lung adenocarcinoma patients and corresponding methylation data of 413 cases were downloaded from The Cancer Genome Atlas (TCGA) database, the methylation levels of SHOX2 and RASSF1A gene promoter regions were calculated, and the difference in methy lation level between normal lung tissues and tumor tissues was analyzed. The clinical data of 54 patients with early-stage lung adenocarcinoma and 31 patients with benign lung tumors who underwent surgery at Drum Tower Hospital Affiliated to Nanjing University Medical School from January 2018 to January 2019 were retrospectively analyzed. The methylation status of SHOX2 and RASSF1A in tumor tissues and normal lung tissues (>5 cm from the edge of the tumor foci) (called clinical samples) was detect, and a positive methylation in the promoter region of either gene was considered as a combination of two genes methylation positivity. Using pathological diagnosis as the gold standard, the efficacy of gene methylation positivity in diagnosing early-stage lung adenocarcinoma was analyzed by receiver operating characteristic (ROC) curve. Patients with >80% of tumor cells in paraffin samples were screened, and mRNA high-throughput sequencing was performed in their tumor tissues and normal lung tissues. The relationship between positive methylation of the two genes and clinicopathological features was analyzed, and the correlation between the promoter region methylation level of the two genes and mRNA expression levels in clinical samples and TCGA database samples was analyzed by Spearman method. Gene set variance analysis (GSVA) method was used to analyze the differences in Kyoto Encyclopedia of Genes and Genomes enrichment pathways between two-gene methylation-positive clinical lung adenocarcinoma samples and corresponding methylation-negative lung adenocarcinoma.Results:In TCGA database, the SHOX2 promoter region methylation island contained 6 sequenced methylation sites, of which sites cg04532033 and cg01557547 methylation levels were higher in lung adenocarcinoma tissues than in normal lung tissues (both P < 0.05); the RASSF1A gene promoter region methylation island contained 11 sequenced methylation sites, and the methylation levels of 6 of these sites in lung adenocarcinoma tissues were higher than those in normal lung tissues (all P < 0.05). Compared with normal lung tissues, the methylation level of SHOX2 promoter region was higher in stage Ⅰ and Ⅱ lung adenocarcinoma tissues (both P < 0.05); the methylation level of RASSF1A promoter region was higher in all stages of lung adenocarcinoma ( P < 0.001). Among 54 patients with early-stage lung adenocarcinoma, 28 were positive for SHOX2 promoter region methylation in tumor tissues, 21 were positive for RASSF1A promoter region methylation, and 40 were positive for combined methylation of both genes; 31 benign lung nodules were negative for SHOX2 and RASSF1A methylation. ROC curve analysis showed that the sensitivity of positive SHOX2 promoter region methylation for diagnosing early-stage lung adenocarcinoma was higher than that of RASSF1A promoter region methylation positivity (51.8% vs. 38.9%), and the area under the curve (AUC) for diagnosis by two-gene methylation positivity was larger than that for diagnosis by SHOX2 or RASSF1A gene methylation positivity alone (0.870 vs. 0.759 and 0.694). The circulating thresholds (Ct) of SHOX2 and RASSF1A methylation tested by real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) in stage Ⅰ and Ⅱ lung adenocarcinoma were lower than those in normal lung tissues (all P < 0.05); patients with two-gene methylation positivity were characterized by older age, longer tumor longest diameter and more advanced pathological stage compared with patients with two-gene methylation negativity (all P < 0.05). In clinical stage Ⅰ-Ⅱ lung adenocarcinoma samples, the Ct of SHOX2 and RASSF1A promoter region methylation tested by qRT-PCR was negatively correlated with their mRNA relative expression levels ( r=-0.43, P = 0.003; r = -0.48, P = 0.001); in TCGA database stage Ⅰ-Ⅱ lung adenocarcinoma samples, the level of SHOX2 promoter region methylation was negatively correlated with its mRNA relative expression level ( r = -0.23, P < 0.001), and the level of RASSF1A promoter region methylation was also negatively correlated with its mRNA relative expression level, but without statistical difference ( r = -0.05, P = 0.310). In two-gene promoter methylation-positive lung adenocarcinoma samples, the pathways related to folate metabolism and DNA stability were upregulated, and the pathways related to vasoconstriction and cell growth and differentiation were downregulated. Conclusions:The combined detection of SHOX2 and RASSF1A promoter region methylation can be used as an indicator for screening and diagnosis of early-stage lung adenocarcinoma. Abnormal promoter region methylation of the two genes may affect multiple tumor-related pathways and promote the occurrence and progression of early-stage lung adenocarcinoma.
RESUMO
Group B streptococcus(GBS), also known as streptococcus agalactis, is a Gram-positive conditionally causative coccus that can colonize healthy humans.GBS is a common pathogen of bacterial meningitis in infants under 3 months of age.GBS serotype Ⅲ and sequence type 17(ST 17)are the most common and virulent, and there is a significant correlation between serotype Ⅲ and ST 17, and erythromycin resistance is high.Penicillin or ampicillin is the first-line drug in China.Children with GBS meningitis are at high risk of poor prognosis.Intrapartum antibiotic prophylaxis(IAP)may be given in the presence of specific risk factors for GBS invasion in newborns. IAP reduced the incidence of early-onset GBS, but did not significantly reduce early-onset mortality and late-onset morbidity.
RESUMO
Paris rugosa(Melanthiaceae) only grows in Yunnan province of China at present, and its chemical constituents have not been systematically studied. In this study, nine compounds, including one new compound pariposide G(1) and eight known compounds of cerin(2), stigmast-4-en-3-one(3), β-ecdysone(4), ophiopogonin C'(5), methyl protogracillin(6), gracillin(7), parissaponin H(8), and parisyunnanoside G(9), were isolated and identified from the ethanol extract of P. rugosa rhizomes by column chromatography methods and semi-preparative high-performance liquid chromatography(HPLC). Compounds 1-9 were isolated from this plant for the first time. The antibacterial and antifungal activities of all the compounds were evaluated. The results showed that ophiopogonin C' had strong inhibitory effects on Candida albicans [MIC_(90)=(4.68±0.01) μmol·L~(-1)] and the fluconazole-resistant strain of C. albicans [MIC_(90)=(4.66±0.02) μmol·L~(-1)].
