Expression analysis and antiviral activity of koi carp (Cyprinus carpio) viperin against carp edema virus (CEV).

Viperin, also known as radical S-Adenosyl methionine domain containing 2 (RSAD2), is an IFN stimulated protein that plays crucial roles in innate immunity. Here, we identified a viperin gene from the koi carp (Cyprinus carpio) (kVip). The ORF of kVip is 1047 bp in length, encoding a polypeptide of 348 amino acids with neither signal peptide nor transmembrane protein. The predicted molecular weight is 40.37 kDa and the isoelectric point is 7.7. Multiple sequence alignment indicated that putative kVip contains a radical SAM superfamily domain and a conserved C-terminal region. kVip was highly expressed in the skin and spleen of healthy koi carps, and significantly stimulated in both natural and artificial CEV-infected koi carps. In vitro immune stimulation analysis showed that both extracellular and intracellular poly (I: C) or poly (dA: dT) caused a significant increase in kVip expression of spleen cells. Furthermore, intraperitoneal injection of recombinant kVip (rkVip) not only reduced the CEV load in the gills, but also improved the survival of koi carps following CEV challenge. Additionally, rkVip administration effectively regulated inflammatory and anti-inflammatory cytokines (IL-6, IL-1ß, TNF-α, IL-10) and interferon-related molecules (cGAS, STING, MyD88, IFN-γ, IFN-α, IRF3 and IRF9). Collectively, kVip effectively responded to CEV infection and exerted antiviral function against CEV partially by regulation of inflammatory and interferon responses.

Performance of the 2019 ACR/EULAR Classification Criteria for IgG4-Related Disease in a Large Chinese Cohort.

OBJECTIVE: The purpose of this research was to ascertain the effectiveness of the newly established criteria for classifying IgG4-related disease (IgG4-RD), as applied to a large Chinese cohort in real-world clinical settings. METHODS: Patient data were procured from the digital health records of 4 prominent academic hospitals. The criterion standard for identifying IgG4-RD patients was from a seasoned rheumatologist. The control group consisted of individuals with other ailments such as cancer, other forms of pancreatitis, infectious diseases, and illnesses that mimic IgG4-RD. RESULTS: A total of 605 IgG4-RD patients and 760 mimickers were available for analysis. The 2019 EULAR/ACR criteria have a sensitivity of 69.1% and a specificity of 90.9% in this large Chinese cohort. IgG4-RD had a greater proportion of males (55.89% vs 36.25%, p < 0.001), an older average age at diagnosis (54.91 ± 13.44 vs 48.91 ± 15.71, p < 0.001), more pancreatic (29.59% vs 6.12%, p < 0.001) and salivary gland (63.30% vs 27.50%, p < 0.001) involvement, and a larger number of organ involvement (3.431 ± 2.054 vs 2.062 ± 1.748, p < 0.001) compared with mimickers. CONCLUSIONS: The 2019 EULAR/ACR criteria are effective in classifying IgG4-RD in Chinese patients, demonstrating high specificity and moderate sensitivity.

Delirium in older patients given propofol or sevoflurane anaesthesia for major cancer surgery: a multicentre randomised trial.

BACKGROUND: Delirium is a common and disturbing postoperative complication that might be ameliorated by propofol-based anaesthesia. We therefore tested the primary hypothesis that there is less delirium after propofol-based than after sevoflurane-based anaesthesia within 7 days of major cancer surgery. METHODS: This multicentre randomised trial was conducted in 14 tertiary care hospitals in China. Patients aged 65-90 yr undergoing major cancer surgery were randomised to either propofol-based anaesthesia or to sevoflurane-based anaesthesia. The primary endpoint was the incidence of delirium within 7 postoperative days. RESULTS: A total of 1228 subjects were enrolled and randomised, with 1195 subjects included in the modified intention-to-treat analysis (mean age 71 yr; 422 [35%] women); one subject died before delirium assessment. Delirium occurred in 8.4% (50/597) of subjects given propofol-based anaesthesia vs 12.4% (74/597) of subjects given sevoflurane-based anaesthesia (relative risk 0.68 [95% confidence interval {CI}: 0.48-0.95]; P=0.023; adjusted relative risk 0.59 [95% CI: 0.39-0.90]; P=0.014). Delirium reduction mainly occurred on the first day after surgery, with a prevalence of 5.4% (32/597) with propofol anaesthesia vs 10.7% (64/597) with sevoflurane anaesthesia (relative risk 0.50 [95% CI: 0.33-0.75]; P=0.001). Secondary endpoints, including ICU admission, postoperative duration of hospitalisation, major complications within 30 days, cognitive function at 30 days and 3 yr, and safety outcomes, did not differ significantly between groups. CONCLUSIONS: Delirium was a third less common after propofol than sevoflurane anaesthesia in older patients having major cancer surgery. Clinicians might therefore reasonably select propofol-based anaesthesia in patients at high risk of postoperative delirium. CLINICAL TRIAL REGISTRATION: Chinese Clinical Trial Registry (ChiCTR-IPR-15006209) and ClinicalTrials.gov (NCT02662257).

Long-term survival in older patients given propofol or sevoflurane anaesthesia for major cancer surgery: follow-up of a multicentre randomised trial.

BACKGROUND: Experimental evidence indicates that i.v. anaesthesia might reduce cancer recurrence compared with volatile anaesthesia, but clinical information is observational only. We therefore tested the primary hypothesis that propofol-based anaesthesia improves survival over 3 or more years after potentially curative major cancer surgery. METHODS: This was a long-term follow-up of a multicentre randomised trial in 14 tertiary hospitals in China. We enrolled 1228 patients aged 65-90 yr who were scheduled for major cancer surgery. They were randomised to either propofol-based i.v. anaesthesia or to sevoflurane-based inhalational anaesthesia. The primary endpoint was overall survival after surgery. Secondary endpoints included recurrence-free and event-free survival. RESULTS: Amongst subjects randomised, 1195 (mean age 72 yr; 773 [65%] male) were included in the modified intention-to-treat analysis. At the end of follow-up (median 43 months), there were 188 deaths amongst 598 patients (31%) assigned to propofol-based anaesthesia compared with 175 deaths amongst 597 patients (29%) assigned to sevoflurane-based anaesthesia; adjusted hazard ratio 1.02; 95% confidence interval (CI): 0.83-1.26; P=0.834. Recurrence-free survival was 223/598 (37%) in patients given propofol anaesthesia vs 206/597 (35%) given sevoflurane anaesthesia; adjusted hazard ratio 1.07; 95% CI: 0.89-1.30; P=0.465. Event-free survival was 294/598 (49%) in patients given propofol anaesthesia vs 274/597 (46%) given sevoflurane anaesthesia; adjusted hazard ratio 1.09; 95% CI 0.93 to 1.29; P=0.298. CONCLUSIONS: Long-term survival after major cancer surgery was similar with i.v. and volatile anaesthesia. Propofol-based iv. anaesthesia should not be used for cancer surgery with the expectation that it will improve overall or cancer-specific survival.

MCU Upregulation Overactivates Mitophagy by Promoting VDAC1 Dimerization and Ubiquitination in the Hepatotoxicity of Cadmium.

Cadmium (Cd) is a high-risk pathogenic toxin for hepatic diseases. Excessive mitophagy is a hallmark in Cd-induced hepatotoxicity. However, the underlying mechanism remains obscure. Mitochondrial calcium uniporter (MCU) is a key regulator for mitochondrial and cellular homeostasis. Here, Cd exposure upregulated MCU expression and increased mitochondrial Ca2+ uptake are found. MCU inhibition through siRNA or by Ru360 significantly attenuates Cd-induced excessive mitophagy, thereby rescues mitochondrial dysfunction and increases hepatocyte viability. Heterozygous MCU knockout mice exhibit improved liver function, ameliorated pathological damage, less mitochondrial fragmentation, and mitophagy after Cd exposure. Mechanistically, Cd upregulates MCU expression through phosphorylation activation of cAMP-response element binding protein at Ser133(CREBS133 ) and subsequent binding of MCU promoter at the TGAGGTCT, ACGTCA, and CTCCGTGATGTA regions, leading to increased MCU gene transcription. The upregulated MCU intensively interacts with voltage-dependent anion-selective channel protein 1 (VDAC1), enhances its dimerization and ubiquitination, resulting in excessive mitophagy. This study reveals a novel mechanism, through which Cd upregulates MCU to enhance mitophagy and hepatotoxicity.

Pelvic metastatic squamous cell carcinoma of unknown primary site: A case report and brief literature review.

RATIONALE: Cancer with unknown primary site is a kind of disease that is difficult to deal with clinically, accounting for 2% to 9% of all newly diagnosed cancer cases. Here, we report such a case with pelvic metastatic squamous cell carcinoma of an unknown primary site and review the relevant literature. PATIENT CONCERNS DIAGNOSES: A 43-year-old Chinese female patient was referred to our hospital and initially diagnosed as "malignant tumor of right adnexal area?, obstruction of right ureter, secondary hydronephrosis". INTERVENTIONS: Thereafter cytoreductive surgery was performed which included a total hysterectomy, left adnexectomy, partial omentum resection, pelvic lymph node dissection, and para-aortic lymph node dissection. The primary lesion could not be identified by supplementary examination and postoperative pathology. The patient was diagnosed as pelvic metastatic squamous cell carcinoma whose primary site was unknown. To prevent a recurrence, we administered adjuvant chemotherapy for the patient. OUTCOMES: The patient was followed up after treatment, complete remission has been maintained for 72 months, and no recurrence or metastasis has been found. LESSONS: Our case demonstrates that surgery combined with chemotherapy could be helpful for pelvic metastatic squamous cell carcinoma of unknown primary site.

Simultaneous Cryogenic Radical and Oxidative Coupling Polymerizations to Polyaniline/Polyacrylamide Conductive Cryogels for Gas Sensing.

The macro-porous structure of polymer cryogels provides an appropriate channel for the adsorption and transport of substances, endowing its application in the field of electrochemical sensing. The combination mode of a polymer matrix and electro-active substance, particularly the distribution of an electro-active substance in the matrix, has an important effect on the overall performance of the sensor. In this work, through the simultaneous oxidation coupling polymerization of aniline (ANI) and radical polymerization of acrylamide (AAm) under cryogenic condition, conductive composite cryogels were prepared, aiming for the uniform distribution of PANI in the PAAm matrix. The possibility of simultaneous polymerizations was symmetrically investigated, and the obtained PANI/PAAm cryogels were characterized. Due to the acid-doping of PANI, the electrical conductivity of PANI/PAAm cryogels could be modulated with acidic and basic gases. Thus, the performance of the gas sensor was studied by making conductive PANI/PAAm cryogel sheets as resistive sensor electrodes. We found that the content of PANI, the sheet thickness and the dry/wet state of the cryogel influenced the response sensitivity and rate as well as the recovery properties. The response duration for HCl and NH3 gas was shorter than 70 and 120 s, respectively. The cyclic detection of HCl gas and the alternate detection of NH3/HCl were achieved. This gas sensor with advantages, including simple preparation, low cost and high sensitivity, would have great potential for the application to monitor the leakage of acidic and basic gases.

Delirium in Older Patients after Combined Epidural-General Anesthesia or General Anesthesia for Major Surgery: A Randomized Trial.

BACKGROUND: Delirium is a common and serious postoperative complication, especially in the elderly. Epidural anesthesia may reduce delirium by improving analgesia, reducing opioid consumption, and blunting stress response to surgery. This trial therefore tested the hypothesis that combined epidural-general anesthesia reduces the incidence of postoperative delirium in elderly patients recovering from major noncardiac surgery. METHODS: Patients aged 60 to 90 yr scheduled for major noncardiac thoracic or abdominal surgeries expected to last 2 h or more were enrolled. Participants were randomized 1:1 to either combined epidural-general anesthesia with postoperative epidural analgesia or general anesthesia with postoperative intravenous analgesia. The primary outcome was the incidence of delirium, which was assessed with the Confusion Assessment Method for the Intensive Care Unit twice daily during the initial 7 postoperative days. RESULTS: Between November 2011 and May 2015, 1,802 patients were randomized to combined epidural-general anesthesia (n = 901) or general anesthesia alone (n = 901). Among these, 1,720 patients (mean age, 70 yr; 35% women) completed the study and were included in the intention-to-treat analysis. Delirium was significantly less common in the combined epidural-general anesthesia group (15 [1.8%] of 857 patients) than in the general anesthesia group (43 [5.0%] of 863 patients; relative risk, 0.351; 95% CI, 0.197 to 0.627; P < 0.001; number needed to treat 31). Intraoperative hypotension (systolic blood pressure less than 80 mmHg) was more common in patients assigned to epidural anesthesia (421 [49%] vs. 288 [33%]; relative risk, 1.47, 95% CI, 1.31 to 1.65; P < 0.001), and more epidural patients were given vasopressors (495 [58%] vs. 387 [45%]; relative risk, 1.29; 95% CI, 1.17 to 1.41; P < 0.001). CONCLUSIONS: Older patients randomized to combined epidural-general anesthesia for major thoracic and abdominal surgeries had one third as much delirium but 50% more hypotension. Clinicians should consider combining epidural and general anesthesia in patients at risk of postoperative delirium, and avoiding the combination in patients at risk of hypotension.

Long-term Survival after Combined Epidural-General Anesthesia or General Anesthesia Alone: Follow-up of a Randomized Trial.

BACKGROUND: Experimental and observational research suggests that combined epidural-general anesthesia may improve long-term survival after cancer surgery by reducing anesthetic and opioid consumption and by blunting surgery-related inflammation. This study therefore tested the primary hypothesis that combined epidural-general anesthesia improves long-term survival in elderly patients. METHODS: This article presents a long-term follow-up of patients enrolled in a previous trial conducted at five hospitals. Patients aged 60 to 90 yr and scheduled for major noncardiac thoracic and abdominal surgeries were randomly assigned to either combined epidural-general anesthesia with postoperative epidural analgesia or general anesthesia alone with postoperative intravenous analgesia. The primary outcome was overall postoperative survival. Secondary outcomes included cancer-specific, recurrence-free, and event-free survival. RESULTS: Among 1,802 patients who were enrolled and randomized in the underlying trial, 1,712 were included in the long-term analysis; 92% had surgery for cancer. The median follow-up duration was 66 months (interquartile range, 61 to 80). Among patients assigned to combined epidural-general anesthesia, 355 of 853 (42%) died compared with 326 of 859 (38%) deaths in patients assigned to general anesthesia alone: adjusted hazard ratio, 1.07; 95% CI, 0.92 to 1.24; P = 0.408. Cancer-specific survival was similar with combined epidural-general anesthesia (327 of 853 [38%]) and general anesthesia alone (292 of 859 [34%]): adjusted hazard ratio, 1.09; 95% CI, 0.93 to 1.28; P = 0.290. Recurrence-free survival was 401 of 853 [47%] for patients who had combined epidural-general anesthesia versus 389 of 859 [45%] with general anesthesia alone: adjusted hazard ratio, 0.97; 95% CI, 0.84 to 1.12; P = 0.692. Event-free survival was 466 of 853 [55%] in patients who had combined epidural-general anesthesia versus 450 of 859 [52%] for general anesthesia alone: adjusted hazard ratio, 0.99; 95% CI, 0.86 to 1.12; P = 0.815. CONCLUSIONS: In elderly patients having major thoracic and abdominal surgery, combined epidural-general anesthesia with epidural analgesia did not improve overall or cancer-specific long-term mortality. Nor did epidural analgesia improve recurrence-free survival. Either approach can therefore reasonably be selected based on patient and clinician preference.

Transcriptomic analyses of humans and mice provide insights into depression.

Accumulating studies have been conducted to identify risk genes and relevant biological mechanisms underlying major depressive disorder (MDD). In particular, transcriptomic analyses in brain regions engaged in cognitive and emotional processes, e.g., the dorsolateral prefrontal cortex (DLPFC), have provided essential insights. Based on three independent DLPFC RNA-seq datasets of 79 MDD patients and 75 healthy controls, we performed differential expression analyses using two alternative approaches for cross-validation. We also conducted transcriptomic analyses in mice undergoing chronic variable stress (CVS) and chronic social defeat stress (CSDS). We identified 12 differentially expressed genes (DEGs) through both analytical methods in MDD patients, the majority of which were also dysregulated in stressed mice. Notably, the mRNA level of the immediate early gene FOS ( Fos proto-oncogene) was significantly decreased in both MDD patients and CVS-exposed mice, and CSDS-susceptible mice exhibited a greater reduction in Fos expression compared to resilient mice. These findings suggest the potential key roles of this gene in the pathogenesis of MDD related to stress exposure. Altered transcriptomes in the DLPFC of MDD patients might be, at least partially, the result of stress exposure, supporting that stress is a primary risk factor for MDD.

[Effect of Tongluo Zhitong (, TLZT) gel preparation on p53 /miR-502-5p /NF-κBp65 in synovial tissue of knee osteoarthritis].

OBJECTIVE: To observe effects of Tongluo Zhitong (, TLZT) gel preparation on p53, miR-502-5p, NF-κBp65 in synovial tissue of knee osteoarthritis (KOA), and to explore mechanism of TLZT gel preparation in treating KOA. METHODS: Thirthy-six Wistar rats aged 8 weeks and weighed 200 to 220 g (meaned 208 g) were randomly divided into normal group, model group and traditional Chinese medicine (TCM) group, 12 rats in each group. KOA model was established by modified Hulth method. After 4 weeks of modeling, TCM group treated with TLZT gel preparation for external use, 3 times daily for 2 weeks;normal group and model group were fed normally without intervention. After treatment, morphological changes of specimens in each group were observed, changes of miR-502-5p in synovial tissue were detected by qPCR, and contents of p53, NF-κBp65, IL-1ß, TNF-α, MMP-13 in synovial tissue were detected by qPCR and Western Blot respectively. RESULTS: (1)Morphological observation of specimens showed that the articular cartilage in model group was hyaline and uneven, the synovial membranes were hypertrophic and proliferative with a large number of inflammatory cells infiltrating, the joint fluid was thicker in texture;the articular cartilage in TCM group was more transparent and smooth, synovial hyperplasia was mild with a small amount of inflammatory cell infiltration, the texture of articular fluid was clear and sparse. (2) Compared with normal group, content of miR-502-5p of synovial tissue in model and TCM group were increased, mRNA and expression of p53 decreased, expression of NF-κBp65, IL-1ß, TNF-α, MMP-13 increased. (3)Compared with model group, content of miR-502-5p in synovial tissue of TCM group decreased (P<0.05), mRNA and protein expression of p53 increased (P<0.05), mRNA and protein expression of NF-κBp65, IL-1ß, TNF-α, MMP-13 decreased (P<0.05). CONCLUSION: Expression of p53, miR-502 -5p, NF -κBp65 in synovial tissue is closely related to synovial hyperplasia and inflammatory reaction, TLZT gel preparation may reduce proliferation and inflammatory reaction of KOA synovium by regulating the expression of p53, miR- 502-5p, NF-κBp65 in synovial tissues.

Rapid UV-radiation synthesis of polyacrylate cryogel oil-sorbents with adaptable structure and performance.

Macro-porous poly(lauryl acrylate) cryogel sheets as oil-sorbents were prepared through UV-radiation cryo-polymerizations in 1, 4-dioxane at low temperatures (-5, -2 and 0 °C) within 30 min. The influences of total monomer concentration, crosslinking monomer amount and polymerization temperature on the formation of cryogels were studied. The chemical structure and porous morphology were characterized through the techniques of Fourier transform infrared spectroscopy, thermal gravimetric analysis, contact angle measurement and scanning electron microscopy, confirming the features of high hydrophobicity, macro-porosity and good thermal stability. As well, the comparison between conventional gels prepared at room temperature and cryogels at lower temperatures was made, showing the higher rate of cryo-polymerization than conventional polymerization under the same UV-radiation condition. The swelling investigation was carried out with several organic solvents and oils. Enhanced performance of oil absorption was observed for those cryogels considering the absorption capacity and absorption rate. Variation of initiator amount and acrylate monomers could also modulate the absorption capacity. Those cryogel oil-sorbents exhibited wide adaptability, good reusability and high-temperature tolerance. Thus, this rapid and low-cost fabrication opens out a novel pathway to prepare efficient oil-sorbents used in waste water treatment.

Further confirmation of netrin 1 receptor (DCC) as a depression risk gene via integrations of multi-omics data.

Genome-wide association studies (GWAS) of major depression and its relevant biological phenotypes have been extensively conducted in large samples, and transcriptome-wide analyses in the tissues of brain regions relevant to pathogenesis of depression, e.g., dorsolateral prefrontal cortex (DLPFC), have also been widely performed recently. Integrating these multi-omics data will enable unveiling of depression risk genes and even underlying pathological mechanisms. Here, we employ summary data-based Mendelian randomization (SMR) and integrative risk gene selector (iRIGS) approaches to integrate multi-omics data from GWAS, DLPFC expression quantitative trait loci (eQTL) analyses and enhancer-promoter physical link studies to prioritize high-confidence risk genes for depression, followed by independent replications across distinct populations. These integrative analyses identify multiple high-confidence depression risk genes, and numerous lines of evidence supporting pivotal roles of the netrin 1 receptor (DCC) gene in this illness across different populations. Our subsequent explorative analyses further suggest that DCC significantly predicts neuroticism, well-being spectrum, cognitive function and putamen structure in general populations. Gene expression correlation and pathway analyses in DLPFC further show that DCC potentially participates in the biological processes and pathways underlying synaptic plasticity, axon guidance, circadian entrainment, as well as learning and long-term potentiation. These results are in agreement with the recent findings of this gene in neurodevelopment and psychiatric disorders, and we thus further confirm that DCC is an important susceptibility gene for depression, and might be a potential target for new antidepressants.

Macroporous Oil-Sorbents with a High Absorption Capacity and High-Temperature Tolerance Prepared through Cryo-Polymerization.

The facile preparation and admirable performance of macro-porous poly(lauryl acrylate)-based oil-sorbents for organic solvents and oils are reported in this manuscript. Cryo-polymerizations of lauryl acrylate (LA) with ethylene glycol dimethacrylate (EGDMA) as the cross-linker were carried out at temperatures below the freezing point of the polymerization mixture. The polymerization medium and pore-forming agent was 1,4-dioxane. The influences of the total monomer concentration, EGDMA content and cryo-polymerization temperature on the structure of the obtained P(LA-co-EGDMA) cryogels were investigated with the techniques of Fourier transform infrared spectroscopy, scanning electron microscopy, contact angle measurement and thermo-gravimetric analysis. Through the modulation of the crosslinking density and porosity of these cryogels, the P(LA-co-EGDMA) oil-sorbents demonstrated a high absorption capacity for organic solvents and oils, recyclability and high-temperature tolerance. The absorption capacity reached 20-21 and 16-17 g/g for toluene and gasoline oil, respectively. Those fabricated sorbents survived high temperatures up to 150 °C without any change in absorption capacity as well as porosity. Considering the convenient synthesis process and absorption performance, the present work offers a remarkable opportunity to bring polymer cryogels to practical application in waste oil clean-up.

Suprapubic tube compared with urethral catheter drainage after robot-assisted radical prostatectomy: A systematic review and meta-analysis.

This meta-analysis aimed to compare the effectiveness of the suprapubic drainage and urethral catheterization after robot-assisted radical prostatectomy (RARP). PubMed, EMBASE, Cochrane Library and China Biology Medicine disc were systematically researched from their inception to December 2017. We selected randomized controlled trials, cohort studies comparing suprapubic tube with urethral catheter drainage in RARP patients. A meta-analysis was performed using R software, and a random-effects model was used to pool the effect size. Ten studies met eligibility criteria (N = 1248), including 3 RCTs, 3 prospective studies and 4 retrospective studies. Suprapubic drainage was associated with a reduction in the penile pain (39.64% [44 of 111]) compared with the UC group (62% [106 of 171]) (pooled RR 0.57, 95% CI 0.31 to 1.02, P = 0.05). However, two groups showed similarity in the overall pain (Postoperative days 1-3: pooled MD -0.26, 95% CI 1.34 to 0.83, P = 0.64; Postoperative days 6-7: pooled MD -0.50, 95% CI -1.54 to 0.54, P = 0.34), urinary incontinence (pooled RR 0.80, 95% CI 0.56 to 1.15, P = 0.23), bladder neck contracture (pooled RR 0.77, 95% CI 0.39 to 1.53, P = 0.45), urinary retention (pooled RR 0.88, 95% CI 0.29 to 2.70, P = 0.82), anastomotic stricture (P = 0.15), urethral stricture (P = 0.84) and bacteriuria (P = 0.40). The present meta-analysis showed that suprapubic drainage may be associated with less penile pain, but there was no conclusive evidence that suprapubic drainage was advantaged in other outcomes. Due to the low quality and small quantity of the available comparative studies, more high-quality randomized trials are needed to provide stronger evidence of the benefits of the two routes.

Anthropometric factors and non-Hodgkin's lymphoma risk: systematic review and meta-analysis of prospective studies.

The associations between anthropometric factors and non-Hodgkin's lymphoma (NHL) risk remain inconclusive. A meta-analysis was performed to clarify these associations. PubMed and Web of Science were searched for relevant prospective observational studies. A random-effects model was used to generate the summary relative risks (RRs) with 95% confidence intervals (CIs). A total of 22 prospective cohort studies, with over 20,000 NHL cases, were included in the present meta-analysis. The summary RRs of NHL risk were 1.06 (95% CI 1.03, 1.09) for each 5 kg/m2 increase in body mass index (BMI), 1.11 (95% CI 1.07, 1.16) for each 5 kg/m2 increase in BMI in early adulthood (age 18-21 years), 1.05 (95% CI 1.01, 1.09) for each 10 kg increase in weight, 1.21 (95% CI 1.15, 1.28) for each 10 kg increase in weight in early adulthood (age 18-21 years), and 1.13 (95% CI 1.10, 1.17) for each 10 cm increase in height. No association was found for waist circumference (WC) and waist-to-hip ratio. By subtypes, all anthropometric factors (but not WC) were associated with an increased risk of diffuse large B-cell lymphoma. Chronic lymphocytic leukemia/small lymphocytic lymphoma was positively associated with BMI in early adulthood and with height, whereas follicular lymphoma was only positively associated with height. In summary, BMI and weight in early adulthood may be more relevant to NHL development than current BMI and weight. These findings emphasize the importance of maintaining a healthy weight throughout the life-course, starting from early life, for NHL prevention. Increased NHL risk with taller stature, which may reflect cumulative exposure to hormones/growth factors and nutrition status in early life, further supports the relevance of early life exposure in the etiology of NHL.

Diagnostic and therapeutic value of progastrin-releasing peptide on small-cell lung cancer: A Single-Center Experience in China.

We aimed to compare the diagnostic efficiency of proGRP and NSE on SCLC and to investigate whether the change of proGRP level would predict therapeutic response. Patients who were firstly diagnosed pathologically in Nanjing Chest Hospital and measured proGRP level consecutively were enrolled in the study. ProGRP level was detected using Elecsys ProGRP Assay. Totally 75 SCLC, 234 NSCLC and 264 benign lung diseases (BLD) were enrolled. Both proGRP and NSE levels in SCLC were significantly higher than those in NSCLC and BLD, and proGRP in extensive stage SCLC was higher than which in limited stage (P ≤ .001). The diagnostic efficiency of proGRP on SCLC was higher than that of NSE, but when the two biomarkers were bind together, the diagnostic efficiency was the best. When SCLC was differentiated from NSCLC and BLD, the cut-off values were 114.35 pg/mL and 162.55 pg/mL respectively. For treatment responsive patients, proGRP level decreased markedly after the first cycle of therapy and kept a continued momentum of decline during treatment. But for unresponsive patients, no obvious decline was observed. ProGRP had higher diagnostic efficiency on SCLC when compared to NSE, and it could better predict therapeutic response of pulmonary target lesions on chemotherapy.

Identification of metabolism-associated genes and pathways involved in different stages of clear cell renal cell carcinoma.

The lack of early diagnostic markers and novel therapeutic targets for clear cell renal cell carcinoma (ccRCC) negatively affects patient prognosis. Cancer metabolism is an attractive area for the understanding of the molecular mechanism of carcinogenesis. The present study attempted to identify metabolic changes from the view of the expression of metabolism-associated genes between control samples and those of ccRCC at different disease stages. Data concerning ccRCC gene expression obtained by RNA-sequencing was obtained from The Cancer Genome Atlas and data on metabolism-associated genes were extracted using the Recon2 model. Following analysis of differential gene expression, multiple differentially expressed metabolic genes at each tumor-node-metastasis disease stage were identified, compared with control non-disease samples: Metabolic genes (305) were differentially expressed in stage I disease, 323 in stage II disease, 355 in stage III disease and 363 in stage IV disease. Following enrichment analysis for differential metabolic genes, 22 metabolic pathways were identified to be dysregulated in multiple stages of ccRCC. Abnormalities in hormone, vitamin, glucose and lipid metabolism were present in the early stages of the disease, with dysregulation to reactive oxygen species detoxification and amino acid metabolism pathways occurring with advanced disease stages, particularly to valine, leucine, and isoleucine metabolism, which was substantially dysregulated in stage IV disease. The xenobiotic metabolism pathway, associated with multiple cytochrome P450 family genes, was dysregulated in each stage of the disease. This pathway is worthy of substantial attention since it may aid understanding of drug resistance in ccRCC. The results of the present study offer information to aid further research into early diagnostic biomarkers and therapeutic targets of ccRCC.

[Suprapubic tube drainage versus transurethral catheterization after robot-assisted radical prostatectomy: A systematic review and meta-analysis].

OBJECTIVE: To compare the effectiveness and safety of suprapubic tube drainage (SPT) with those of transurethral catheterization (TUC) after robot-assisted radical prostatectomy (RARP). METHODS: We searched PubMed, EMBASE, Cochrane Library, CNKI, VIP, WanFang Data and China Biology Medicine Disc from their inception to December 2017 for randomized controlled trials and cohort studies comparing the effectiveness and safety of SPT and TUC after RARP. Two reviewers independently screened the literature, extracted data and assessed the risk of bias of the included studies, followed by a meta-analysis with the RevMan 5.3 software. RESULTS: Ten studies met the eligibility criteria and were included in this meta-analysis, involving 1 248 cases of RARP, 482 in the SPT group and the other 766 in the TUC group. The severity of postoperative penile pain was significantly lower in the SPT than in the TUC group (RR = 0.63, 95% CI: 0.50 to 0.80, P = 0.0002), but no statistically significant differences were shown between the two groups in the overall pain severity at 1－3 days (［MD = －0.26, 95% CI: －1.34 to 0.83, P = 0.64］ and 6－7 days postoperatively (［MD = －0.50, 95% CI: －1.54 to 0.54, P=0.34］, urinary incontinence (RR = 0.80, 95% CI: 0.56 to 1.15, P = 0.23), bacteriuria (RR = 0.63, 95% CI: 0.20 to 1.97, P = 0.42), bladder neck contracture (RR = 0.77, 95% CI: 0.39 to 1.53, P = 0.45), urethral stricture (RR = 1.32, 95% CI: 0.08 to 20.7, P = 0.84), anastomotic stricture (RR = 0.20, 95% CI: 0.02 to 1.79, P = 0.15), or urinary retention (RR = 0.93, 95% CI: 0.43 to 2.00, P = 0.85). CONCLUSIONS: SPT after RARP is associated with a lower severity of postoperative penile pain than TUC, but there are no statistically significant differences between the two strategies in other parameters. This conclusion, however, has to be further supported by more higher-quality randomized controlled trials.

Impact of inhalational versus intravenous anaesthesia on early delirium and long-term survival in elderly patients after cancer surgery: study protocol of a multicentre, open-label, and randomised controlled trial.

INTRODUCTION: Elderly patients who have solid organ cancer often receive surgery. Some of them may develop delirium after surgery and delirium development is associated with worse outcomes. Furthermore, despite all of the advances in medical care, the long-term survival in cancer patients is far from optimal. Evidences suggest that choice of anaesthetics during surgery, that is, either inhalational or intravenous anaesthetics, may influence outcomes. However, the impact of general anaesthesia type on the occurrence of postoperative delirium is inconclusive. Although retrospective studies suggest that propofol-based intravenous anaesthesia was associated with longer survival after cancer surgery when compared with inhalational anaesthesia, prospective studies as such are still lacking. The purposes of this randomised controlled trial are to test the hypotheses that when compared with sevoflurane-based inhalational anaesthesia, propofol-based intravenous anaesthesia may reduce the incidence of early delirium and prolong long-term survival in elderly patients after major cancer surgery. METHODS AND ANALYSIS: This is a multicentre, open-label, randomised controlled trial with two parallel arms. 1200 elderly patients (≥65 years but <90 years) who are scheduled to undergo major cancer surgery (with predicted duration ≥2 hours) are randomised to receive either sevoflurane-based inhalational anaesthesia or propofol-based intravenous anaesthesia. Other anaesthetics and supplemental drugs including sedatives, opioids and muscle relaxants are administered in both arms according to routine practice. The primary early outcome is the incidence of 7-day delirium after surgery and the primary long-term outcome is the duration of 3-year survival after surgery. ETHICS AND DISSEMINATION: The study protocol has been approved by the Clinical Research Ethics Committees of Peking University First Hospital (2015[869]) and all participating centres. The results of early and long-term outcomes will be analysed and reported separately. TRIAL REGISTRATION NUMBER: ChiCTR-IPR-15006209; NCT02662257; NCT02660411.
