Objective To investigatethe relationship between gastroesophageal reflux disease (GERD) symptoms and clinicopathological characteristics, p53 expression, and survival of Chinese patients with esophageal adenocarcinoma. Methods A total of 3882 patients with esophageal adenocarcinoma, 970 matched patients with esophageal squamous cell carcinoma, and 970 matched patients with gastric cardia adenocarcinoma were included to compare the incidence of GERD symptoms. Patients with esophageal adenocarcinoma were divided into two groups according to the presence and absence of GERD symptoms. The differences in clinicopathological characteristics and p53 expression between the two groups were compared by chi-square test, and the differences in survival between the two groups were compared by landmark analysis. Results The incidence of GERD symptoms increased successively in esophageal squamous cell carcinoma, esophageal adenocarcinoma, and gastric cardia adenocarcinoma. In patients with esophageal adenocarcinoma, the proportions of male, less than 65 years old, lower thoracic tumors, tumors without squamous cell carcinoma, poorly differentiation, early tumors (stage 0-I), and p53-positive tumors in the group with GERD symptoms were higher than those in the group without GERD symptoms; moreover, the long-term survival (≥15 years) was better. Conclusion GERD symptom is an important clinical sign of esophageal adenocarcinoma. It is closely related to specific clinicopathological characteristics, p53 overexpression, and good long-term prognosis.

Objective The aim of this study was to assess the impact of bisphenol A (BPA) and its substitute, bisphenol F (BPF), on the colonic fecal community structure and function of mice.Methods We exposed 6-8-week-old male C57BL/6 mice to 5 mg/(kg·day) and 50 μg/(kg·day) of BPA or BPF for 14 days. Fecal samples from the colon were analyzed using 16S rRNA sequencing. Results Gut microbiome community richness and diversity, species composition, and function were significantly altered in mice exposed to BPA or BPF. This change was characterized by elevated levels of Ruminococcaceae UCG-010 and Oscillibacter and decreased levels of Prevotella 9 and Streptococcus. Additionally, pathways related to carbohydrate and amino acid metabolism showed substantial enrichment. Conclusion Mice exposed to different BP analogs exhibited distinct gut bacterial community richness, composition, and related metabolic pathways. Considering the essential role of gut bacteria in maintaining intestinal homeostasis, our study highlights the intestinal toxicity of BPs in vertebrates.

The identification of the components absorbed in serum of platycosides in total saponins fraction of Platycodonis Radix is great significance, but there are still great challenges. In this study, 8 types of 44 primordial components from Platycodon saponins were firstly identified using the ultra-performance liquid chromatography-linear ion trap electrostatic field orbitrap high resolution mass spectrometry (UPLC-LTQ-Orbitrap-MS) equipped with the software of Compound Discoverer 3.2 and Trace finder 2.1. Then, the platycosides and their deglycosylated metabolites were used as the template molecules to construct the intestinal microbiota mediated method to identify the primary components and the prototypes in serum. As results, 57 components originating from 44 prototypes of platycosides were identified from drug-containing plasma. Those compounds consist of 12 prototypes of platycosides and 45 metabolites, while the prototypes in serum are also deglycosylated metabolites of other platycosides. The results showed that the intestinal microbiota mediated method could be applied to identify the metabolites of platycosides in total saponins fraction of Platycodonis Radix; and reveal the potential existing forms of prototypes of platycosides in plasma; In addition, it could clearly illustrate the one to many and many to one network of the prototypes and metabolites of platycosides. All animal protocols were approved by the Animal Ethics Committee of Jiangxi University of Traditional Chinese Medicine (No.JZLLSC-202100322).

Abstract: Objective　To investigate the species distribution and the antifungal susceptibility of fungi originating from positive blood cultures in Guangdong, so as to provide a basis for the rational use of antifungal drugs in clinical fungal bloodstream infections. Methods All data were collected for retrospective study from monitoring units of the Guangdong Fungal Disease Surveillance Network between 2019-2021, including clinical characteristics, species distribution and antifungal susceptibility. Results A total of 3 589 fungi strains were isolated, most of which were Candida spp. (86.5%, 3 105/3 589). The most common species was Candida albicans (36.6%, 1 315/3 589), followed by Candida tropicalis (17.4%, 1 626/3 589) and Candida parapsilosis (14.5%, 520/3 589). There were 42.1%(1 512/3 589) of strains isolated from ICU. The proportions of Candida albicans strains were 40.0%-50.0% among ICU, general surgery, organ transplantation and emergency department. Candida tropicalis (60.0%, 144/240) was the most common species in hematology department. Both Cryptococcus neoformans (35.4%, 69/195) and Talaromyces marneffei (35.9%,70/195) were common in infection department. All of the Candida isolates were of wild-type (WT) phenotype to amphotericin B. Resistance rates of caspofungin and micafungin for Candida spp. ranged from 0.0% to 4.2%. The resistance rates of Candida tropicalis to fluconazole and voriconazole were 42.3% and 38.9%, which were significantly higher than other common Candida spp. The cryptococcus neoformans strains were totally of WT phenotype to fluconazole and voriconazole. Conclusions Candida albicans is the most common species originating from positive blood cultures in Guangdong Province. Common Candida strains are highly sensitive to echinocandins and amphotericin B. Candida tropicalis has a high resistance rate to triazole drugs.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

OBJECTIVE: To explore application value and effectiveness of virtual reality technology combined with isokinetic muscle strength training in the rehabilitation of patients after anterior cruciate ligament (ACL) reconstruction surgery. METHODS: Forty patients who underwent ACL reconstruction surgery from December 2021 to January 2023 were selected and divided into control group and observation group according to treatment methods, 20 patients in each group. Control group was received routine rehabilitation training combined with isokinetic muscle strength training, including 15 males and 5 females, aged from 17 to 44 years old, with an average of (29.10±8.60) years old. Observation group was performed virtual reality technology combined with isokinetic muscle strength training, including 16 males and 4 females, aged from 17 to 45 years old with an average of (30.95±9.11) years old. Lysholm knee joint score, knee extension peak torque, and knee flexion peak torque between two groups at 12 (before training) and 16 weeks (after training) after surgery were compared. RESULTS: All patients were followed up for 1 to 6 months with an average of (3.30±1.42) months. There were no statistically significant difference in Lysholm knee joint score, peak knee extension peak torque, and peak knee flexion peak torque between two groups (P>0.05) before training. After training, Lysholm knee joint score, knee extension peak torque, and knee flexion peak torque of both groups were improved compared to before training (P<0.05);there were significant difference in Lysholm knee joint score, knee extension peak torque, and knee flexion peak torque between two groups(P<0.05). CONCLUSION The application of virtual reality technology combined with isokinetic muscle strength training could promote recovery of knee joint function and enhance muscle strength in patients after ACL reconstruction surgery in further.

Objective The aim of this study is to investigate the efficacy of using transcatheter aortic valve replacement(TAVR)with self-expanding valve(SEV)to treat patients with pure aortic regurgitation(PAR)and to understand the preliminary experience of such procedure.Methods A total of 20 PAR patients who underwent TAVR using the TaurusElite system at Wuhan Asia Heart Hospital and Wuhan Asia Heart Disease Hospital from April 2022 to May 2023 were included in the study.Patient baseline data,echocardiographic data,follow-up data during hospitalization and 30 days after the procedures were collected and analyzed.Results The mean age of the patients was(73.5±5.5)years,and the mean STS score was(8.7±3.6)％.16(16/20)cases had severe PAR before the procedure.After TAVR treatment,the success rate of the procedure was 20/20,with only 1 case of valve-in-valve(ⅥⅤ).The 30-day follow-up results showed that none of the 20 patients experienced death,disabling stroke,myocardial infarction,and conversion to surgery.The degree of residual PAR after the procedure was none or mild in all patients.The interventional outcome was ideal.Conclusions The preliminary experience shows that,with strict patient selection and standardized procedural steps,using TAVR with SEV to treat patients with PAR could have high feasibility and ideal early clinical outcomes and can potentially be popularized.Such experience will be further validated in future clinical trials.

Background: Cervical cancer is still present a major public health problem, especially in developing countries. In International Federation of Gynaecology and Obstetrics 2018, allowing assessment of retroperitoneal lymph nodes by imaging and/or pathological findings and, if deemed metastatic, the case is designated as stage IIIC (with r and p notations). Patients with lymph node metastases have lower overall survival (OS), progression free survival (PFS), and survival after recurrence, especially those who have unresectable macroscopical positive lymph nodes. Retrospective analysis suggests that there may be a benefit to debulking macroscopic nodes that would be otherwise difficult to sterilize with standard doses of radiation therapy. However, there are no prospective study reporting that resecting macroscopic nodes before concurrent chemoradiation therapy (CCRT) would improve PFS or OS of cervical cancer and no guidelines for surgical resection of bulky lymph nodes. The CQGOG0103 study is a prospective, multicenter and randomized controlled trial (RCT) evaluating lymph node dissection on stage IIICr of cervical cancer. Methods Eligible patients are histologically confirmed cervical squamous cell carcinoma, adenocarcinoma, adeno-squamous cell carcinoma. Stage IIICr (confirmed by computed tomography [CT]/magnetic resonance imaging/positron emission tomography/CT) and the short diameter of image-positive lymph node ≥15 mm. 452 patients will be equally randomized to receive either CCRT (pelvic external-beam radiotherapy [EBRT]/extended-field EBRT + cisplatin [40 mg/m2] or carboplatin [the area under curve=2] every week for 5 cycles + brachytherapy) or open/minimally invasive pelvic and para-aortic lymph node dissection followed by CCRT. Randomization is stratified by status of para-aortic lymph node. The primary endpoint is PFS. Secondary endpoints are OS and surgical complications. A total of 452 patients will be enrolled from multiple hospitals in China within 4 years and followed up for 5 years.
