Objective: To analyze the differences in bile acid profiles during different pregnancy durations of patients with intrahepatic cholestasis of pregnancy (ICP), so as to provide a reference for early prevention and treatment of ICP and optimization of maternal-infant health outcomes. Methods: Pregnant women who underwent routine prenatal examinations and delivered at Hangzhou Obstetrics and Gynecology Hospital from 2021 to 2023 were selected as study subjects. According to the ICP guidelines (2020), pregnant women were categorized into normal group, mild ICP group, and moderate/severe ICP group. Age, parity, and gravidity were collected through the obstetric electronic medical record system, liver function indicators and seven bile acid levels were collected through the hospital's laboratory information system. Differences in bile acid profiles across pregnancy durations among the three groups were compared. Results: A total of 238 pregnant women were enrolled, including 57 cases (23.95%) in the normal group, 136 cases (57.14%) in the mild ICP group, and 45 cases (18.91%) in the moderate/severe ICP group. There were statistically significant differences between the three groups in total bile acid (TBA), cholic acid (CA), chenodeoxycholic acid (CDCA), glycochenodeoxycholic acid (GCDCA), glycocholic acid (GCA), taurocholic acid (TCA) levels (all P<0.05). Compared with the normal group, CA, GCDCA and GCA, and TCA were higher in the mild and moderate/severe ICP groups; compared with the mild ICP group, GCA was higher in the moderate/severe ICP group (all P<0.05). Significant differences were observed in the levels of GCDCA, GCA, and TCA among three groups pregnant women in the early, mid, and late pregnancy (all P<0.05). Compared with the normal group, mild ICP group had higher GCDCA and GCA in the early and mid pregnancy; moderate/severe ICP group had higher TCA in the early pregnancy and higher GCDCA and GCA in the late pregnancy. Compared with the mild ICP group, mild ICP group had higher TCA in the early pregnancy and the moderate/severe ICP group had higher GCA in the late pregnancy. Conclusions GCDCA, GCA, and TCA levels remain higher in ICP patients than in normal pregnant women across all pregnancy durations. Personalized perinatal management plans can be developed based on bile acid profile dynamics to optimize maternal-fetal outcomes.

Objective:To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test.Methods:This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ2 test. A kappa test was used to compare the consistency between groups. Results:After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea ( Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences ( P < 0.001). Conclusion:The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.

Objective:To analyze the clinical characteristics and risk factors of juvenile dermatomyositis (JDM) with relapses by comparing clinical features, treatment and disease course among JDM patients with and without relapses.Methods:A retrospective analysis of 102 JDM patients from Children's Hospital of Nanjing Medical University between March 2017 and March 2021 was carried out. Patients were divided into two groups based on whether a JDM relapse had occurred or not. Initial clinical features, laboratory tests and treatment were compared between the two groups. T-test or Mann-Whitney U test was used for measurement data, chi-square test or fisher exact probability was used for count data. The features associated with risk of relapses were analyzed by multivariate logistic regression. Results:Among 102 children with JDM, twenty patients (19.6%) relapsed during drug reduction or after drug withdrawal. The mean duration to the first relapse was 3.24 years (range: 9 months to 7 years). Myositis specific antibodies (MSA) were positive for 8 (40.0%) patients with relapses. With 5 cases were anti-nuclear matrix protein 2 positive, 2 cases were anti-transcription interme-diary factor 1 gamma positive, 1 case was anti-signal recognition particle (SRP) positive, the other 12 cases were MSA negative. By binary logistic regression analysis, we found that peripheral calcinosis [ OR(95% CI)=17.54(1.55, 198.64), P=0.021], and interstitial lung disease [ OR(95% CI)=3.83(1.27, 11.59), P=0.017] were independently related to JDM with relapses. Fifty-three patients (51.9%) received methylpre-dnisolone pulse therapy for initial treatment and 13 (65.0%) patients with relapses received methylprednisolone pulse for initial treatment. There was no significant difference between the two groups ( χ2=1.70 , P=0.193). Tumor necrosis factor alpha antagonist combined with methotrexate (MTX) had achieved good results in clinical treatment in children with relapses. Conclusion:The risk of relapses is high in children with JDM. Calcinosis and interstitial lung disease at disease onset can predict a relapsing disease course. Aggressive treatment is urgently demanded for patients with JDM, especially those with relapses.

Objective:To investigate the different effects of different treatment regimens in resistant Kawasaki disease (KD) and to provide evidence for clinical treatment.Methods:Forty-nine inpatient children with resistant KD from July 2017 to June 2019 in Children's Hospital of Nanjing Medical University were enrolled into this study. Treatment and follow-up were still in progress. Rank sum test and χ2/Fisher test were used for statisic. Results:The incidence of resistance in infliximab group was significantly lower than that of intravenous immunoglobulin (IVIG) retreated group ( P<0.05). Sixteen cases were treated with 5 mg/kg infliximab (IFX), and 33 cases received methylprednisolone and an additional dose of IVIG. Nine cases who were resistant to IVIG and methylprednisolone were treated with IFX, 6 patients responded to IFX, 3 of them were treated with cyclosporine. Coronary artery changes were followed up. Coronary artery lesions (CALs) were improved in the IFX group, CALs occurred in 12(36%) patients received IVIG and methylprednisolone, 4 of them were improved( χ2=0.633 , P=0.426). Patients were followed up for 3-24 months, the incidence of CALs persistence was statistically significantly different between the two groups (0 vs 24%, P=0.021]. Conclusion:IFX might be an effective and tolerable treatment for resistant KD.

Objective To investigate the efficacy and safety of tocilizumab inpatients with refractory systemic'onset juvenile idiopathic arthritis (SoJIA),and to provide a new option for the treatment of this severe disease.Methods We retrospectively studied 25 cases of hospitalized patients with refractory SoJIA treated withtocilizumab,of whom 22 had data that fit for analysis,from May 2005 to February 2016.Data of 22 cases were collected retrospectively from physicians in charge of the patients.Children with SoJIA were treated with nonsteroidal antiinflammatory drugs (NSAIDs),Glucocorticoid (GC),methotrexate,cyclosporin A,etanerceptetc before,but still in high disease activity due to inadequate response were involved.Weretrospective analyzedthe laboratory test results like C'reactive protein (CRP),Erythrocyte sedimentation rate (ESR),Ferritin and other inflammatory index.Improvement of pain,fever,rash,hepatosplenomegaly and lymphadenectasis of active SoJIA (disease course ≥6 months,and inadequate response to NSAIDs and GC) after tocilizumab treatment (Body weight ≥30 kg,8 mg/kg;Body weight＜30 kg,12 mg/kg,per 4 weeks) were analyzed.Safety data of 22 cases were collected throughout the treatment period including neutropenia,infections,anaphylaxis and elevated liver enzymes etc.We also retrospectively analyzedthe dose change of GC and the long'term effect.Dichtomous paramenters were compared teween groups using thex2 test.Continuous parameters were compared using the analysis of uariance.Results In comparison to the indices before the treatment,the level of CRP [(8.7±2.2) mg/L vs (111.6±74.4) mg/L,F=5.192,P=0.002],ESR [(6.4±6.3) mm/1 h) vs (65.6±24.3) mm/1 h,F=50.393,P=0.000],white blood cell (WBC) [(8.4±2.5)×109/L vs (17.6±8.6)×109/L,F=9.321,P=0.000],Neutrophil count [(4.9±2.4)×109/L vs.(14.4±8.7)×109/L,F=10.541,P=0.000],blood platelet (PLT) [(269.5±79.2)×109/L vs (405.4± 145.3)×109/L,F=5.704,P=0.000] and globulin [(19.2±4.1) g/L vs (30.1±3.8) g/L,F=22.896,P=0.000] decreased rapidly and hemoglobin [(118.3±9.0) g/L vs (108.5±9.8) g/L,F=4.693,P=0.002] increased significantly at 24 weeks after Tocilizumab (TCZ) treatment.Clinical manifestationssuch as fever,rash,hepatosplenomegaly,joint swelling and pain were significantly improved.GC dose [(1.25±3.8) mg·kg-1·d-1 vs (16.2±12.8) mg·kg-1·d-1,F=8.21,P=0.000] were significantly reduced after TCZ treatment (P＜0.05);American College of Rheumatology (ACR) Pedi 30/50/70/90 was improved after TCZ treatment.Adverse events occurred in 3 cases of 25 children,who were not included in the statistical analysis group.Conclusion This retrospective case series has demonstrated the efficacy of tocilizumab in SoJIA,low incidence of adverse reactions.Further studies are needed to be developed because this case series haslimited sample size.

Objective To explore the diagnosis and treatment of five children with tuberculosis with arthritis as the initial manifestation. Methods The clinical features, laboratory tests and imaging manifestation of 5 children with joint tuberculosis were retrospectively analyzed. Results The course of disease was different. All the five patients were males (mean age 8.5 ±2.9 years old) and suffered from articular symptoms as initial feature. Four of them were diagnosed and treated as rheumatoid arthritis by other hospitals for up to three years, two patients have tuberculosis contact history, and another two patients were found with bone destruction, and one patient has pathologic fracture. Conclusions Tuberculosis is easily misdiagnosed as juvenile idiopathic arthritis , which deserves attention from a pediatric rheumatology physician.

Cervical cancer is a serious disease endangering the health of women, which is next only to breast cancer and colon cancer.There are nearly 130 000 new cases of cervical cancer arise in China each year, accounting for 1/5 of the total number of new cases in the world.Epidemiological survey has found that cervical cancer is related to various factors, such as human papilloma virus infection, multiple sexual partners, smoking, premature sexual life, sexually transmitted diseases, economic status and immunosuppression.Cervical cancer is pathologically characterized by cervical dysplasia cervical atypical hyperplasia (mild, moderate, severe) to carcinoma in situ and to infiltrating carcinoma.Female vagina is a relatively anoxic and unique dynamic micro ecological system colonized with a large number of bacteria.And the vaginal microflora is the kernel of maintaining vaginal micro ecological balance.The uterine cervix is directly exposed to the vagina, and is closely related to vaginal microbes.However, there are few reports on the direct relationship between cervical cancer and vaginal microbes.In this review, the roles and significance of vaginal microbial imbalance and common vaginal infections in cervical cancer will be discussed from different angles.

Objective To explore the clinical significance of blood flow reserve fraction in the treatment of coronary stent implantation.Methods A total of 46 patients with positive coronary angiography were included.Criteria for positive coronary angiography:coronary angiography confirmed at least a coronary artery stenosis was more than or equal to 50%.According to the results,the patients were divided into the control group(24 cases) and observation group(22 cases).Results 1.There was no significant difference in baseline level(P>0.05);2.The operation time,number of stents and the contrast agent dosage of the observation group were (63.20±9.92)min,(0.50±0.65) and (182.94±39.30)mL,which were significantly less than those of the control group,the differences were statistically significant(operation time t=2.69,P=0.01;number of stents t=2.56,P=0.02;contrast agent dosage t=6.98,P=0.00).There was no significant difference between the control group and the observation group in angina pectoris and MACE attack.Conclusion Blood flow reserve score is an important guiding parameter for PCI treatment of coronary artery stenosis.

Objective To analyze the clinical features and laboratory data of 10 patients with macrophage activation syndrome (MAS) complicating systemic onset juvenile idiopathic arthritis (soJIA),which were characterized by acute severe liver injury.Methods Data of 10 patients with soJIA/MAS from Nanjing Children's Hospital were collected retrospectively.The clinical features,laboratory findings,treatment,outcomes and prognosis were analyzed.Results In the total 10 patients,female (6/10) outnumbered male.Their age ranged from 1.5 to 9.5 years old (average 5.2±2.6).The most remarkable clinical manifestations were severe liver injury without systemic features,representing as hepatomegaly (10/10),splenomegaly (2/10) and strikingly increased transaminase (10/10,median:ALT 1 445 U/L,AST 885 U/L).Central nervous system dysfunction and hemorrhages were recorded in 20％ of the patients.Two patients had pulmonary infection.Laboratory data showed that platelet count was less than normal or precaution value (10/10,≤262×10g/L).Hyperferritinaemia (10/10,median:17 329 mg/ml) and soluble CD25 elevation (median:3 140 U/ml) were common in the soJIA/MAS patients.Evidence of macrophage hemophagocytosis was found in 90％ of the patients (9/10) who underwent bone marrow aspiration.Pathological findings of liver biopsy from 1 patient revealed massive infiltration of mononuclear cells in the portal tracts.Nearly all patients (9/10) received intravenous pulse methylprednisolone therapy,combined with cyclosporine A and high-dose intravenous immunoglobulin.Eight patients had good outcome.Only 2 patients were complicated with severe interstitial lung disease during 12-months follow-up.Conclusion MAS should be considered when patients with soJIA represents acute severeliver injury without systemic features combined with other laboratory data.Intravenous pulse methylprednisolone and cyclosporine A therapy may improve the prognosis of soJIA/MAS.

Objective To investigate the clinical features of ischemic stroke in patients with nasopharyngeal carcinoma.Methods The clinical data of the nasopharyngeal carcinoma patients with ischemic stroke treated at the First Affiliated Hospital of Guangxi Medical University between January 2006 and December 2013 were collected.Results Among 3 822 patients with nasopharyngeal carcinoma l0 patients suffered from acute ischemic stroke.The 10 patients were males and their age ranged from 39 to 70 years old,with an average age of 51 years.All of the patients were found with squamous cell carcinoma,with metastasis in 7 of them.Among the 10 patients,only 3 patients had with traditional risk factors for ischemic stroke,but no traditional risk factor was found in other 7 patients;2 patients showed single lesion in brain and 8 patients with two or more lesions due to the blockage of multiple cerebral arteries;7 patients showed an elevated plasma D-dimer level.Conclusion It is suggested that the acute ischemic stroke occurring in the patients with nasopharyngeal carcinoma commonly lacks traditional risk factors,with elevated plasma D-dimer levels and multiple lesions due to involvement of several cerebral arteries.
