Exploring bacterial community assembly in vadose and saturated zone soil for tailored bioremediation of a long-term hydrocarbon-contaminated site.

Indigenous soil microbial communities play a pivotal role in the in situ bioremediation of contaminated sites. However, research on the distribution characteristics of microbial communities at various soil depths remains limited. In particular, there is little information on the assembly of microbial communities, especially those with degradation potential, in the vadose and saturated zones of hydrocarbon-contaminated sites. In this study, 18 soil samples were collected from the vadose zone and saturated zone at a long-term hydrocarbon-contaminated site. The diversity, composition, and driving factors of assembly of the soil bacterial community were determined by high-throughput sequencing analysis. Species richness and diversity were significantly higher in the vadose zone soils than in the saturated zone soils. Significant differences in abundance at both the phylum and genus levels were observed between the two zones. Soil bacterial community assembly was driven by the combination of pollution stress and nutrients in the vadose zone but by nutrient limitations in the saturated zone. The abundance of dechlorinating bacteria was greater in the saturated zone soils than in the vadose zone soils. Compared with contaminant concentrations, nutrient levels had a more pronounced impact on the abundance of dechlorinating bacteria. In addition, the interactions among dechlorinating bacterial populations were stronger in the saturated zone soils than in the vadose zone soils. These findings underscore the importance of comprehensively understanding indigenous microbial communities, especially those with degradation potential, across different soil layers to devise specific, effective in situ bioremediation strategies for contaminated sites.

The value of transitory protective stomas during primary debulking surgery for advanced epithelial ovarian cancer-- a retrospective cohort study.

OBJECTIVES: Limited data are available on patients with advanced-stage epithelial ovarian cancer (OC) who require ostomy during primary cytoreductive surgery. This study aimed to investigate the application of postoperative and long-term oncological results from transitory protective stoma (TPS) formation during primary debulking surgery (PDS) for OC. METHODS: This is a retrospective cohort study with a single center. We identified patients with stage III-IV OC who underwent colon resection and anastomosis. Depending on the methods used after colorectal anastomosis and the outcomes of surgical resection, the patients were stratified into three groups: resection and end-to-end anastomosis, resection and ostomy, or R1 resection. Demographic and clinical data were analyzed. RESULTS: 84 patients underwent colorectal resection during cytoreduction for FIGO stage III-IV OC. Patients undergoing ostomy were more likely to have a longer mean operative time (266 vs. 283 vs. 236 min; P=0.003) and to undergo rectosigmoid resection at the time of cytoreductive surgery (56.0% vs. 22.7%, P=0.007). Their postoperative feeding (7 vs. 1 vs. 3 d, P<0.001) and exhaustion (6 vs. 3 vs. 3, P<0.001) times were similar to those of patients with R1 resection and much earlier than those of patients with intestinal anastomosis. The first normal time (35 d) and half-life (14.68 d) of CA125 after surgery were significantly better in patients with TPS group. The overall incidence of complications was the same, and there was no significant difference in the 30-day readmission rate. The overall quality of life assessment was significantly lower in the R1 resection group. CONCLUSIONS: TPSs can accelerate postoperative recovery and the initiation of postoperative chemotherapy, reduce the risk of mortality and disease progression and limit the incidence of complications.

Correlation between the changes of brain amplitude of low-frequency fluctuation and cognitive impairment in patients with neuropsychiatric lupus.

PURPOSE: To explore the relationship between brain function changes and clinical serological indicators and behavioral cognitive assessment in patients with neuropsychiatric systemic lupus erythematosus (NPSLE), and understand the pathogenesis of NPSLE from the perspective of imaging. METHODS: The resting-state functional imaging data, clinical serological, and behavioral cognitive assessment scores of 28 patients with NPSLE and 22 healthy controls (HC) were prospectively collected. The resting-state amplitude of low-frequency fluctuation (ALFF) values obtained from the analysis and processing were correlated with the serological data and behavioral cognitive assessment scores to determine the relationship between these data. RESULTS: The average age of the patients of the NPSLE group was older than that of the HC group; significant differences in education level, Auditory Verbal Learning Test Hua Shan Version (AVLT-H), and Trail Making Test scores were observed between the two groups. The NPSLE group demonstrated increased brain activity in the insula, precentral gyrus, and superior temporal gyrus, and decreased brain activity in the superior parietal gyrus. The ALFF value of the insula positively correlated with the Anti-ß2gp1 antibody and negatively correlated with the anti-nucleosome antibody and the AVL-recall (RC) score. The ALFF of the precentral gyrus negatively correlated with the AVL-immediate recall (I). The ALFF value of the superior temporal gyrus negatively correlated with the AVL-RC score. The left superior parietal gyrus positively correlated with the c-reactive protein. The right superior parietal gyrus positively correlated with the System Lupus Erythematosus Disease Activity Index and negatively correlated with the AVL-I score. CONCLUSION: Patients with NPSLE show different brain activity changes in different brain regions, and the abnormal brain regions are correlated with certain lupus antibodies, inflammatory factors, and cognitive assessment, thereby suggesting that the correlation between the three could provide novel insights into the pathogenesis of NPSLE.

The perception of childbearing sense of coherence among Chinese couples: a qualitative study.

BACKGROUND: Although childbearing health care is wellness-based and promotes normal physiology, it is in a medical model and focuses on risk aversion and disease prevention. The salutogenic theory might provide an alternative perspective to health care concerning childbearing, supporting health-promoting factors, not solely on avoiding adverse events. However, there is a dearth of qualitative research exploring couples' perceptions of childbearing from the salutogenic lens. This study aimed to explore perceptions and experiences concerning childbearing among couples in the perinatal period and identify salutogenic aspects of it. METHODS: The qualitative descriptive study adopted a directed content analysis to analyse data from a semi-structured and individual interview with 25 purposively selected Chinese couples between July 2022 and December 2022. The concepts of the sense of coherence (SOC) from the salutogenic theory were used as the theory framework for coding. RESULTS: Definitions and content for the salutogenic aspects of Chinese couples' perception of childbearing sense of coherence were developed. For comprehensibility of childbearing, four subthemes were extracted (the challenge to health and endurance; transition to and identification with the new role; conflict and reconciliation in relationships; resistance and compromise between social culture and personal development). For manageability of childbearing, two subthemes were extracted (helplessness and hope of childbearing; self-doubt and self-assurance of childbearing). For meaningfulness of childbearing, three subthemes were extracted (personal realisation; family bonding and harmony; the continuation of life). CONCLUSIONS: The findings of this study could give a greater understanding in maintaining couples' health in the perinatal period from the salutogenic lens and provide a guide to further research that the salutogenic theory could bring a health and wellness-focused agenda in practice and policy-making in the perinatal period.

Patients' experience with chimeric antigen receptor T-cell therapy for DLBCL in China: a qualitative study.

PURPOSE: The experiences of patients with diffuse large B-cell lymphoma (DLBCL) treated with chimeric antigen receptor (CAR) T-cell therapy have received little attention. This study aimed to explore the treatment experiences of patients with relapsed or refractory (R/R) B-cell lymphoma during CAR T-cell therapy in China. METHODS: This descriptive qualitative study was conducted using face-to-face semi-structured interviews with 21 DLBCL patients 0-2 years after CAR-T infusion. Two researchers independently coded the interviews in MAXQDA 2022, and the original data were analyzed by conventional content analysis. RESULTS: Four themes emerged from the transcripts: (1) physiological distress, (2) functional impacts, (3) psychological experience, and (4) support requirement. Participants expressed 29 short-term or long-term symptoms related to their disease and treatment, influencing their daily life and function in a social setting. The participants expressed different negative emotions, polarized expectations about efficacy, and over-reliance on authoritative medical care. Their major concerns and hopes were achieving life goals, being treated with respect, obtaining more information about CAR T-cell therapy, and receiving government financial sponsorship. CONCLUSIONS: The patients experienced short-term and long-term symptoms of physical distress. Patients who have experienced failure in CAR T-cell therapy also experience strong negative emotions, such as dependency and guilt. They also require authentic spiritual and financial information that is authentic. Our study may guide the development of standardized and comprehensive nursing care for R/R DLBCL patients undergoing CAR T-cell therapy in China.

Recent Increased Loading of Carbonaceous Pollution from Biomass Burning in the Baltic Sea.

Black carbon (BC), spheroidal carbonaceous particles (SCP), and polycyclic aromatic hydrocarbons (PAH) are carbonaceous pollutants affecting the climate, environment, and human health. International regulations limit their emissions, and the present emissions are followed by monitoring programs. However, the monitoring programs have limited spatio-temporal coverage and only span the last decades. We can extend the knowledge of historical emission rates by measuring pollution levels in radiometrically dated marine and lacustrine sediment sequences. Here we present measurements of BC, SCP, and PAH from a sediment sequence sampled in the Öresund strait, between Denmark and Sweden and dated back to CE 1850. Our data show a massive increase in the burial rates of all measured pollutants starting in the 1940s. The pollution deposition peaked in the 1970-1980s and declined through the 1990s. However, the declining trend was reversed in the 2000s. Source appointment of PAHs shows a relatively higher contribution of emissions from wood-burning since CE 2000. This coincides with a change towards the increased use of biomass for both municipal and regional energy production in Scandinavia. Our results demonstrate that changes in energy production have caused changes in the delivery of carbonaceous pollution to marine environments. The increase in particle emissions from wood burning is potentially posing a future environmental and health risk.

[Therapeutic observation on horizontal penetration needling for residual dizziness after repositioning maneuver in patients with benign paroxysmal positional vertigo].

OBJECTIVE: To observe the effect of horizontal penetration needling at vertigo auditory area and balance area on residual dizziness after successful repositioning maneuver in patients with benign paroxysmal positional vertigo (BPPV). METHODS: Sixty-six patients with residual dizziness after successful repositioning maneuver for BPPV were randomly divided into an observation group (34 cases, 1 case dropped off) and a control group (32 cases, 2 cases dropped off). The patients in the observation group were treated with horizontal penetration needling at vertigo auditory area and balance area, once every other day; three times were taken as a course of treatment, and two courses of treatment were given. The patients in the control group received no acupuncture and medication. The dizziness handicap inventory (DHI) and visual analogue scale (VAS) scores were observed before treatment and after 1 and 2 courses of treatment. RESULTS: Except for the emotional score of DHI in the control group after 1 course of treatment, the sub item scores and total scores of DHI and VAS scores in the two groups after treatment were lower than those before treatment (P<0.01, P<0.05). After 1 and 2 courses of treatment, the function scores, emotion scores, total scores of DHI and VAS scores in the observation group were lower than those in the control group (P<0.01). CONCLUSION: Whether acupuncture or not, residual dizziness after repositioning maneuver for BPPV can be relieved within 2 weeks; horizontal penetration needling at vertigo auditory area and balance area could improve dizziness symptoms and shorten the course of disease.

[Revelation of Fu's subcutaneous needling therapy on the development of acupuncture and moxibustion].

By analyzing Fu 's subcutaneous needling phenomenon, the attribute of Fu 's subcutaneous needling therapy in traditional acupuncture, the innovation and the role in the development of traditional acupuncture were demonstrated. The authors believe that the de-meridian in Fu 's subcutaneous needling therapy is similar to the connotation of meridian before the Han dynasty, the de-acupoint phenomenon in Fu 's subcutaneous needling therapy reproduces the acupoint evolution, and the sites of needle insertion of this therapy are partially overlapped with the location of traditional acupoints. In manipulation, the technique of Fu 's subcutaneous needling therapy is derived from the traditional acupuncture technique and it is also in reference to the theory and the method of modern medicine, such as muscle energy technology and fasciology. The needle device and the sweeping technique are the most essential innovation of Fu 's subcutaneous needling therapy. Fu 's subcutaneous needling therapy has the distinct attribute of traditional acupuncture.

[Analysis on relationship between syndrome differentiation of migraine and acupuncture effect].

The problems of the syndrome differentiation of migraine in acupuncture treatment were collected, e.g. inconsistency of syndrome differentiation, unclear staging of syndrome differentiation, lack of standardization in comparison between syndrome differentiation and non-differentiation, insufficient research on the factors of syndrome differentiation. In view of the exiting problems, focusing on two aspects of migraine, namely syndrome differentiation and acupuncture effect, the clinical treatment and research are conducted in migraine treated with acupuncture based on syndrome differentiation. It is believed that the comprehensive observation of the relationship between syndrome differentiation and acupuncture effect, as well as the analysis of the relevant factors of syndrome differentiation of migraine should be the focus in future research.

Fibroblast growth factor 21 inhibited ischemic arrhythmias via targeting miR-143/EGR1 axis.

Ventricular arrhythmia is the most common cause of sudden cardiac death in patients with myocardial infarction (MI). Fibroblast growth factor 21 (FGF21) has been shown to play an important role in cardiovascular and metabolic diseases. However, the effects of FGF21 on ventricular arrhythmias following MI have not been addressed yet. The present study was conducted to investigate the pharmacological action of FGF21 on ventricular arrhythmias after MI. Adult male mice were administrated with or without recombinant human basic FGF21 (rhbFGF21), and the susceptibility to arrhythmias was assessed by programmed electrical stimulation and optical mapping techniques. Here, we found that rhbFGF21 administration reduced the occurrence of ventricular tachycardia (VT), improved epicardial conduction velocity and shorted action potential duration at 90% (APD90) in infarcted mouse hearts. Mechanistically, FGF21 may improve cardiac electrophysiological remodeling as characterized by the decrease of INa and IK1 current density in border zone of infarcted mouse hearts. Consistently, in vitro study also demonstrated that FGF21 may rescue oxidant stress-induced dysfunction of INa and IK1 currents in cultured ventricular myocytes. We further found that oxidant stress-induced down-regulation of early growth response protein 1 (EGR1) contributed to INa and IK1 reduction in post-infarcted hearts, and FGF21 may recruit EGR1 into the SCN5A and KCNJ2 promoter regions to up-regulate NaV1.5 and Kir2.1 expression at transcriptional level. Moreover, miR-143 was identified as upstream of EGR1 and mediated FGF21-induced EGR1 up-regulation in cardiomyocytes. Collectively, rhbFGF21 administration effectively suppressed ventricular arrhythmias in post-infarcted hearts by regulating miR-143-EGR1-NaV1.5/Kir2.1 axis, which provides novel therapeutic strategies for ischemic arrhythmias in clinics.

[Horizontal penetration needling method for headache].

The manipulation and key points of professor FAN Gang-qi 's horizontal penetration needling method for headache were introduced. This acupuncture method selects local acupoints of head, including occipital acupoint group, temporal acupoint group, frontal acupoint group and vertex acupoint group. The needles are shallowly and horizontally inserted at acupoints, with needle end towards the focus or headache site. The needle retaining time is long (6 h). This method is commonly used in the treatment of migraine, cervicogenic headache and tension-type headache. The manipulation is standard with better repeatability.

Clear Cell Odontogenic Carcinoma: a Clinicopathological and Immunocytochemical Analysis.

Clear cell odontogenic carcinoma (CCOC) is a rare odontogenic tumor associated with aggressive clinical behavior, metastasis and low survival. To date, only 67 cases have been described in the English language literature, and an understanding of the behavior of CCOC has been based on limited case reports. The aim of the research was to further reveal the features of CCOC. We report 5 new cases of CCOC, with a mean age of 52.4 years. The clinical and histopathologic data of the disease obtained from earlier literature (95 cases) and the 5 new cases were analyzed. Data were extracted, including demographics, histopathologic findings, clinical presentation, primary treatment and outcomes. Immunohistochemical results revealed that the cancer is positive for AE1/AE3, EMA and CK19, negative for smooth muscle actin SMA, Vim and S-100. EWSR1 translocation was also observed in the new cases, which may help in the diagnosis of CCOC. Metastases of CCOC were rare, but the local recurrence rate of CCOC rose to 42%. The best treatment for patients with CCOC is wide local excision combined with regional lymph node dissection.

A six-CpG-based methylation markers for the diagnosis of ovarian cancer in blood.

DNA methylation markers in the peripheral blood are able to be applied to treat epithelial cancer. Nevertheless, the diagnostic potential value of it for ovarian cancer (OV) has not been studied. The study aimed to explore the difference of DNA methylation in peripheral blood between OV patients and healthy women. Firstly, the whole blood of DNA methylation data was provided by the Gene Expression Omnibus (GEO) database. The linear model was applied to the identification of significantly differentially expressed methylated CpG sites (differentially methylation sites [DMP]), and the further screen of co-expression CpG sites (Co-DMP). A total of 2812 DMPs were identified, and weighted gene co-expression network analysis helped to obtain seven co-expression modules. Among them, the yellow module was the most related to OV. Co-DMPs (167) in the yellow module were mainly distributed near the transcription start sites. However, most of them were not in the CpG island. Least absolute shrinkage and selection operator (LASSO) regression analysis was applied to the identification of stable OV-related blood biomarkers that six Co-DMPs (cg00134539, cg00226923, cg25268718, cg25697314, cg25839227, cg26574610) with the highest frequency were found as potential biomarkers. Finally, the diagnostic classifier was established using the support vector machine (SVM) with the accuracy rate of 87.1% and 74.5% in training data set and validation data set, respectively. To sum up, a new feature was provided here for the diagnosis of OV, which is helpful for the diagnosis and individualized treatments of early OV.

Coriolus versicolor alleviates diabetic cardiomyopathy by inhibiting cardiac fibrosis and NLRP3 inflammasome activation.

Coriolus versicolor (CV) is a traditional medicine and food mushroom. Our previous study demonstrated that CV extract exhibited anti-hyperglycemia and anti-insulin resistance effects. However, the effect of CV on cardiac function in diabetic cardiomyopathy (DCM) remains unclear. Therefore, we aimed to investigate the effect of CV on cardiac function in diabetes mellitus (DM) rats. We found that the cardiac dysfunction of DM rats was markedly improved by CV extract treatment. CV extract administration significantly attenuated cardiac fibrosis in DM rats, which was accompanied by suppressed transforming growth factor beta 1 (TGF-ß1)/Smad signaling as indicated by decreased levels of TGF-ß1, p-Smad2, and p-Smad3 and increased Smad7 expression. Moreover, CV extract treatment significantly alleviated cardiac inflammation as shown by decreased levels of NLRP3 receptor, cleaved caspase-1, IL-1ß, and IL-18 in DM rats at least partly due to the inhibition of the NF-κB. In addition, high-glucose treatment induced cardiac fibrosis and increased cardiac inflammation in cardiac fibroblast cells, but these effects were ameliorated by CV extract treatment. Therefore, we conclude that the protective effect of CV on DCM is associated with the suppression of TGF-ß1/Smad signaling and attenuation of NLRP3 inflammasome activation, suggesting that CV extract may be a potential therapeutic agent for DCM.

[Compliance Control Strategy in the Practical Randomized Controlled Trial Study of Electroacupuncture Combined with Behavior Control for Overweight and Simple Obesity].

Electroacupuncture (EA) has been extensively used in clinical treatment of obesity. The effectiveness relies not only on the correct diagnosis and rational treatment, but also on the voluntary cooperation of patients, that is the satisfactory compliance. The patient compliance refers to his/her submissiveness and executive ability to medical advice, which is the indispensable factor for the clinical efficacy. The strength of it depends on the patient himself/herself, and moreover is improved through some therapeutic strategies. Based on the emphasis of individual treatment in the real world, the practical randomized controlled trial (RCT) study pays attention to patient's compliance at the beginning of trial design. In this paper, in terms of the influential factors and control strategies, the compliance of simple obesity patient in the practical RCT study was summarized systematically.

BACKGROUND: To investigate the efficacy and advantage of combining situ-morcellation with continuous-fill-mattress suture compared with conventional morcellation and suture in laparoscopic myomectomy. METHODS: One hundred sixteen patients who underwent laparoscopic myomectomy from March 2014 to October 2016. INTERVENTIONS: Patients were divided into combining situ-morcellation with continuous-fill-mattress suture group (n = 62) and conventional group (n = 54), and subsequent statistical analysis the clinical data of the 2 groups. RESULTS: The combining situ-morcellation with continuous-fill-mattress suture group shows significantly decrease of surgery time, incision size, blood loss, postoperative drainage volume and time, postoperative vent time, hospital stay and the loss of hemoglobin value. Moreover, there is significant significance between the 2 groups in the surgery time (P = .018), the postoperative drainage volume (P = .000), and the loss of hemoglobin value (P = .000). CONCLUSIONS: The combining situ-morcellation with continuous-fill-mattress suture shows significant advantages in shortening surgery time and reducing blood loss compared with conventional group in laparoscopic myomectomy.

Exploration on the construction of discipline of clinical medicine and clinical talent team: a case study of the construction of "Two-hundred Talent" team / 上海交通大学学报（医学版）

Currently, exploring the "World-class" disciplinary construction is a vital strategy in China. Since 2015, Shanghai Jiao Tong University School of Medicine started the project of establishing two distinguish teams—the academic clinicians and clinical investigators ("Two-hundred Talent" team), to fuel the development of clinical research. After two years of practice, both advantages and bottlenecks were found. The advantage contains: increasing selection rate among talent projects, increasing influential output, elevating capacity in clinical research. The bottlenecks contain: unbalanced disciplinary development, poor awareness of the importance of clinical research, lack of relevant supporting policies. In order to improve the quality of the clinical research and the two talent clinical research teams, institutional innovation, personalized supporting system, establishment of clinical research center, training of clinical research nurses are essential.
