简介：AbstractBackground:The Chinese appropriate use criteria (AUC) for coronary revascularization was released in 2016 to improve the use of coronary revascularization. This study aimed to evaluate the association between the appropriateness of coronary revascularization based on the Chinese AUC and 1-year outcomes in stable coronary artery disease (CAD) patients.Methods:We conducted a prospective, multi-center cohort study of stable CAD patients with coronary lesion stenosis ≥50%. After the classification of appropriateness based on Chinese AUC, patients were categorized into the coronary revascularization group or the medical therapy group based on treatment received. The primary outcome was a composite of death, myocardial infarction, stroke, repeated revascularization, and ischemic symptoms with hospital admission.Results:From August 2016 to August 2017, 6085 patients were consecutively enrolled. Coronary revascularization was associated with a lower adjusted hazard of 1-year major adverse cardiovascular and cerebrovascular events (MACCEs; hazard ratio [HR]: 0.62; 95% confidence interval [CI]: 0.45–0.86; P = 0.004) than medical therapy in patients with appropriate indications (n = 1617). No significant benefit in 1-year MACCEs was found after revascularization compared to after medical therapy in patients with uncertain indications (n = 2658, HR: 0.81; 95% CI: 0.52–1.25; P = 0.338) and inappropriate indications (n = 1810, HR: 0.80; 95% CI: 0.51–1.23; P = 0.308).Conclusions:In patients with appropriate indications according to Chinese AUC, coronary revascularization was associated with significantly lower risk of MACCEs at 1 year. No benefit was found in coronary revascularization in patients with inappropriate indications. Our findings provide evidence for using Chinese AUC to guide clinical decision-making.Clinical trial registration:NCT02880605. https://www.clinicaltrials.gov.

简介：AbstractObjective:To identify potential early diagnostic markers for hepatitis B progression to primary liver carcinoma using routine immunological tests based on 6 cytokine combinations.Methods:Eight hundred and ninety-nine patients with hepatitis B progressing to early primary liver carcinoma admitted to and treated at Changhai Hospital, Naval Military Medical University, Shanghai, China between March 2015 and June 2017 were included in this observational study, including 666 patients with HBsAg+, HBeAb+, HBcAb+ liver carcinoma and 233 patients with HBsAg+, HBeAg+, HBcAb+ liver carcinoma. Receiver operating characteristic (ROC) curves were used to evaluate the efficiency of the different cytokine in the diagnosis of hepatocellular carcinoma in patients with hepatitis B. This study was approved by the Institutional Review Board of Changhai Hospital, Naval Military Medical University, China (approval No. CHEC2020-080) on June 6, 2020.Results:Changed levels of interleukin (IL)-1β, IL-2R, IL-8, and tumor necrosis factor (TNF)-α were statistically significant (P < 0.05). The area under the ROC curve, sensitivity, specificity, positive predictive value, negative predictive value, and Youden index for the diagnosis of primary liver carcinoma using the combination of IL-1β, IL-2R, IL-8, and TNF-α were 0.938, 79.2%, 96.7%, 96%, 82.0%, 0.759, respectively. The serum alpha-fetoprotein level in patients with primary liver carcinoma was positively correlated with IL-2R (r=0.3502, P < 0.001), IL-8 (r=0.1558, P=0.0273), and TNF-α (r=0.2544, P < 0.001) levels. The equation fitted to the results was logit(P)=0.086+ 0.01 × IL-2R-0.001 × IL-8-0.033 × TNF-α-0.041 × IL-1β.Conclusion:Our study establishes a novel, potentially valuable diagnostic model based on four cytokines related to the early stages of liver carcinoma.

简介：AbstractImportance:Congenital tuberculosis (TB) is a rare, potentially fatal disease. There is currently a lack of detailed clinical information available regarding this disease.Objective:This retrospective study investigated the clinical manifestations, treatment, and long-term prognosis of congenital TB.Methods:Patients were treated in Beijing Children’s Hospital, Capital Medical University (Beijing, China) between 2009 and 2018. Their demographic data, maternal and family histories, symptoms and signs, treatment information, and follow-up data were retrospectively collected using the hospital’s electronic information system.Results:Ten infants with congenital TB were enrolled. The mean gestational age was 36.6 ± 2.2 weeks and mean birth weight was 2517 ± 487 g. All 10 patients exhibited fever, nine patients (90%) had anemia, and six patients (60%) had extrauterine growth retardation. On chest computed tomography scans, all 10 patients presented multiple pulmonary nodules and four patients (40%) had mediastinal adenopathy. Nine out of ten (90%) completed the T-spot test, and eight of them (8/9, 89%) were positive. Anti-TB treatment was initiated upon diagnostic confirmation. All patients (100%) received combined treatment with isoniazid (INH) and rifampicin (RIF). Eight of 10 patients (80%) received combined treatment with INH, RIF, and pyrazinamide. The survival rate was 100%. One patient was lost to follow-up and four patients are currently continuing treatment. Three of nine patients (33%) achieved normal developmental milestones at 6 months of age.Interpretation:Early diagnosis based on maternal history, typical imaging results, and timely treatment can improve outcomes in infants with congenital TB.

简介：AbstractObjective:To investigate the effect of early versus late amniotomy after induction of labor (IOL) with vaginally administered misoprostol.Methods:This randomized clinical trial was conducted at the Department of Obstetrics and Gynecology, Menoufia University, from May 2019 to March 2020, and included 120 nulliparous women at term (≥ 37 weeks’ gestation) undergoing IOL. Computer-generated randomization was used to randomize the participants into either the early amniotomy group (3 cm cervical dilatation; n = 60) or the late amniotomy group (7 cm cervical dilatation; n = 60). All participants received misoprostol (25 µg) vaginally to induce labor. The primary outcome was the induction-to-delivery interval, defined as the time from the initiation of IOL to the time of delivery.Results:Women in the early amniotomy group had a shorter duration of labor (12.60 ± 5.36 h) than those in the late amniotomy group (16.67 ± 7.26 h). The mean time from rupture of the fetal membrane to delivery was significantly shorter in the late (2.51 ± 0.36 h) than in the early amniotomy group (3.1 ± 0.89 h). There was no statistically significant difference between the groups in terms of maternal complications (fever, nausea, vomiting, and uterine hyperstimulation) or neonatal complications (meconium-stained liquor, APGAR score <7 at 1 and 5 min, and neonatal intensive care unit admission).Conclusions:IOL using vaginally administered misoprostol followed by early amniotomy was accompanied by a shorter duration of labor and decreased use of oxytocin. There was no significant difference between the early and late amniotomy groups in terms of the rate of cesarean section or maternal and neonatal complications.

简介：AbstractBackground:Pregnancy-associated breast cancer (PABC) is a special type of breast cancer that occurs during pregnancy and within 1 year after childbirth. With the rapid social development and the adjustment of reproductive policies in China, the average age of females at first childbirth is increasing, which is expected to lead to an increase in the incidence of PABC. This study aimed to accumulate clinical experience and to investigate and summarize the prevalence, diagnosis, and treatment of PABC based on large multicenter samples in China.Methods:According to the Chinese Society of Breast Surgery, a total of 164 patients with PABC in 27 hospitals from January 2016 to December 2018 were identified. The pregnancy status, clinicopathological features, comprehensive treatment methods, and outcomes were retrospectively analyzed. Survival curves were plotted using the Kaplan-Meier method.Results:A total of 164 patients of PABC accounted for 0.30% of the total number of cases in the same period; of which, 83 patients were diagnosed during pregnancy and 81 patients during lactation. The median age of PABC was 33 years (24-47 years). Stage I patients accounted for 9.1% (15/164), stage II 54.9% (90/164), stage III 24.4% (40/164), and stage IV 2.4% (4/164). About 9.1% (15/164) of patients were luminal A. Luminal B patients accounted the most (43.3% [71/164]). About 15.2% (25/164) of patients were human epidermal growth factor receptor 2 (Her-2) overexpression and 18.9% (31/164) of patients were triple-negative breast cancer. For pregnancy breast cancer, 36.1% (30/83) of patients received direct surgery and 20.5% (17/83) received chemotherapy during pregnancy. About 31.3% (26/83) chose abortion or induction of labor. The median follow-up time was 36 months (3-59 months); 11.0% (18/164) patients had local recurrence or distant metastasis and 3.0% (5/164) died.Conclusions:It is safe and feasible to standardize surgery and chemotherapy for PABC.

简介：AbstractThere is increasing evidence that cell-free DNA (cfDNA) in spent culture media (SCM) can be amplified for genetic testing. Therefore, this paper reviews the characteristics of cfDNA, including its fragment size, amount, origin, as well as some factors affecting the success rate of its amplification, together to provide researchers with a more comprehensive perspective on embryonic cfDNA. The origin of cfDNA in SCM is complicated and poses challenges to the interpretation of genetic test results. Advanced molecular techniques should distinguish between embryonic and contaminated DNA to maximize the success rate of amplification and analysis. Recent data showed that the type of culture medium, assisted hatching or not, the type of amplification kit, and fresh or thawed embryos were not related to the success rate of amplification, but the length of culture time might affect the success rate. The longer culture time, the more cfDNA is available in the SCM. Then we focused on the concordance between trophectoderm (TE), inner cell mass, whole embryo, and embryonic cfDNA. Despite successful amplification, the concordance between TE and embryonic cfDNA was low. In summary, non-invasive genetic testing using SCM could represent a major advance in future single embryo selection, however, contamination and timing for media collection are key factors affecting the results, and current non-invasive cfDNA testing should not be directly applied to clinical practice. Further research is needed to improve the methods used for testing techniques and genetic analysis to achieve greater accuracy and trace its origins before it can be used in the clinics.

简介：AbstractBackground:As a non-invasive and effective diagnostic method for small intestinal bacterial overgrowth (SIBO), wild-use of breath test (BT) has demonstrated a high comorbidity rate in patients with diarrhea-predominant irritable bowel syndrome (IBS-D) and SIBO. Patients overlapping with SIBO respond better to rifaximin therapy than those with IBS-D only. Gut microbiota plays a critical role in both of these two diseases. We aimed to determine the microbial difference between IBS-D overlapping with/without SIBO, and to study the underlying mechanism of its sensitivity to rifaximin.Methods:Patients with IBS-D were categorized as BT-negative (IBSN) and BT-positive (IBSP). Healthy volunteers (BT-negative) were enrolled as healthy control. The patients were clinically evaluated before and after rifaximin treatment (0.4 g bid, 4 weeks). Blood, intestine, and stool samples were collected for cytokine assessment and gut microbial analyses.Results:Clinical complaints and microbial abundance were significantly higher in IBSP than in IBSN. In contrast, severe systemic inflammation and more active bacterial invasion function that were associated with enrichment of opportunistic pathogens were seen in IBSN. The symptoms of IBSP patients were relieved in different degrees after therapy, but the symptoms of IBSN rarely changed. We also found that the presence of IBSN-enriched genera (Enterobacter and Enterococcus) are unaffected by rifaximin therapy.Conclusions:IBS-D patients overlapping with SIBO showed noticeably different fecal microbial composition and function compared with IBS-D only. The better response to rifaximin in those comorbid patients might associate with their different gut microbiota, which suggests that BT is necessary before IBS-D diagnosis and use of rifaximin.Registration:Chinese Clinical Trial Registry, ChiCTR1800017911.

简介：AbstractBackground:Colorectal cancer is harmful to the patient’s life. The treatment of patients is determined by accurate preoperative staging. Magnetic resonance imaging (MRI) played an important role in the preoperative examination of patients with rectal cancer, and artificial intelligence (AI) in the learning of images made significant achievements in recent years. Introducing AI into MRI recognition, a stable platform for image recognition and judgment can be established in a short period. This study aimed to establish an automatic diagnostic platform for predicting preoperative T staging of rectal cancer through a deep neural network.Methods:A total of 183 rectal cancer patients’ data were collected retrospectively as research objects. Faster region-based convolutional neural networks (Faster R-CNN) were used to build the platform. And the platform was evaluated according to the receiver operating characteristic (ROC) curve.Results:An automatic diagnosis platform for T staging of rectal cancer was established through the study of MRI. The areas under the ROC curve (AUC) were 0.99 in the horizontal plane, 0.97 in the sagittal plane, and 0.98 in the coronal plane. In the horizontal plane, the AUC of T1 stage was 1, AUC of T2 stage was 1, AUC of T3 stage was 1, AUC of T4 stage was 1. In the coronal plane, AUC of T1 stage was 0.96, AUC of T2 stage was 0.97, AUC of T3 stage was 0.97, AUC of T4 stage was 0.97. In the sagittal plane, AUC of T1 stage was 0.95, AUC of T2 stage was 0.99, AUC of T3 stage was 0.96, and AUC of T4 stage was 1.00.Conclusion:Faster R-CNN AI might be an effective and objective method to build the platform for predicting rectal cancer T-staging.Trial registration:chictr.org.cn: ChiCTR1900023575; http://www.chictr.org.cn/showproj.aspx?proj=39665.

简介：AbstractObjective:To evaluate the survival outcomes for a cohort of nasopharyngeal cancer with intracranial extension (ICE) treated with induction chemotherapy (ICT) followed by chemo-intensity-modulated radiotherapy (CTRT) at a tertiary cancer center.Methods:We retrospectively analyzed 45 patients with histologically proven, non-metastatic NPC with ICE treated at our institute between October 2008 and October 2016. Patients were classified as minor ICE or major ICE, based on the extent of ICE. All the patients received 2-3 cycles of a taxane-based ICT regimen followed by CTRT. Radiotherapy was delivered with "riskadapted" intensity-modulated radiotherapy (IMRT) technique in all patients.Results:After a median follow up of 45 months (range: 8-113 months), the estimated 5-year DFS, LRFS, DMFS, and OS of the entire cohort was 58%, 82%, 67% and 74% respectively. On multivariate analysis, histological subtype was an independent predictor of LRFS, and age was an independent predictor of DFS. The extent of ICE showed only a trend towards worse DFS (P= 0.06). None of the factors significantly predicted for DMFS or OS. Gender, N-stage, and response to ICT did not significantly affect any of the outcomes. Grade 2 or worse subcutaneous fibrosis was seen in 22% of patients and grade 2 or worse xerostomia was seen in 24% of patients at last follow up. Thirty-three percent of the patients developed clinical hypothyroidism at last follow up. None of the patients experienced any neurological or vascular complications.Conclusions:Taxane-based induction chemotherapy followed by chemo-intensity modulated radiotherapy resulted in excellent locoregional control and survival with acceptable toxicities in patients of nasopharyngeal cancer with intracranial extension. Distant metastasis continues to be the predominant problem in these patients.
