Objective:To investigate the correlation between computed tomography (CT) findings and serum micrornA-497 (miR-497), carbohydrate polypeptide antigen 24-2 (CA24-2) and hepatitis B surface antigen (HBsAg) expression in patients with colorectal cancer (CRC).Methods:A total of 64 CRC patients admitted to the Jiangsu Cancer Hospital from January 2021 to December 2022 were prospectively selected, and the surgical pathological results were used as the gold standard. Preoperative CT examination and serum miR-497, CA24-2 and HBsAg levels were performed in all patients. The CT images of the patients were analyzed. Pearson correlation analysis was used to evaluate the correlation between CT findings and serum miR-497, CA24-2 and HBsAg expression levels in CRC patients.Results:The CT imaging features of CRC patients were as follows: The intestinal wall was semi-annular in 37.50%(24/64), annular in 32.81%(21/64), localized thickening in 29.69%(19/64), the intestinal lumen was irregular and narrow, and most of the periintestinal fat was blurred in 59.38%(38/64). 67.19%(43/64) showed uneven enhancement, 51.56%(33/64) had lymph node metastasis and 43.75%(28/64) had liver metastasis. Lymph node metastasis in CRC patients was correlated with serum miR-497 and CA24-2 levels (all P<0.05), but not with serum HBsAg levels ( P>0.05). Liver metastasis in CRC patients was associated with serum HBsAg expression ( P<0.05), but not with serum miR-497 and CA24-2 levels (all P>0.05). Other CT findings of CRC patients were not correlated with serum miR-497, CA24-2 and HBsAg levels (all P>0.05). Pearson correlation analysis showed that lymph node metastasis in CRC patients was negatively correlated with the expression level of serum miR-497 ( r=-0.491, P<0.05), while positively correlated with the expression level of serum CA24-2 ( r=0.506, P<0.05). There was no correlation with serum HBsAg expression level ( P>0.05). The occurrence of liver metastasis in CRC patients was negatively correlated with the expression level of serum HBsAg ( r=-0.529, P<0.05), but was not correlated with the expression levels of serum miR-497 and CA24-2 (all P>0.05). Conclusions:CT imaging findings can evaluate the biological behavior of tumor cells in CRC patients to a certain extent, and have a certain correlation with the expression levels of serum miR-497, CA24-2 and HBsAg, which can reflect the lymph node and liver metastasis of tumors, and provide a basis for clinical comprehensive treatment and prognosis prediction of patients.

This study delves into the pivotal factors influencing the consensus process within traditional Chinese medicine guideline development, with the objective of augmenting the quality of this process through methodological recommendations aimed at elevating standardization.

Semi-structured qualitative interviews were used to interview guideline leaders, working groups and consensus groups to explore the pertinent elements impacting the credibility of consensus and gather insights into the constitution and progression of the consensus methodology.

The study encompassed interviews with 26 participants, yielding 212 codes that were subsequently categorized into five domains: establishment of the consensus group, integration of patient participation, adeptness of the meeting moderator, preparation for consensus formulation, and overarching factors influencing consensus. The research distilled three fundamental phases for forming a consensus group and delineated 17 fundamental tenets for applying the consensus methodology.

In forthcoming guideline development endeavors, it is advisable to bolster methodological training ahead of the consensus process while ensuring comprehensive engagement of methodologists. Encouraging experts to navigate differences judiciously and prioritizing meticulous methodology and evidentiary groundwork are recommended. The process should involve openly disclosing the selection of consensus group members, heightening the involvement of patients, and effective management and disclosure of conflicts of interest. This collective approach helps curtail bias, enhance transparency, bolster reliability, and fortify the scientific rigor of consensus outcomes.

Objective To study the protective effect of the sodium selenite and benazepril on renal interstitial fibro-sis(RIF) in rat model of unilateral ureteral obstruction(UUO) and its mechanism. Methods The male SD of clean grade rats were randomly divided into sham-operation group,UUO group(UUO model was established by li-gating unilateral ureter), UUO+ sodium selenite group group(sodium selenite 0.2 mg/kg·d gavage), UUO+benazepril group(benazepril 10 mg/kg·d gavage),with 18 in each group.At day 7,14 and 21 after thetreatment, 6 rats selected randomly from each group were killed.The extent of RIF was evaluated by HE and Masson staining of the renal tissue. The expression of connective tissue growth factor(CTGF),transforming growth factor-β1(TGF-β1), alpha smooth muscle actin(α-SMA) andⅢ collagen(ColⅢ) were detected by immunohistochemical method.The protein expression of CTGF and TGF-β1 were detected by Western blot. Chemical colorimetric method was used to detecte the contents of supper oxide dismutase (SOD),malondialdehyde (MDA) and glutathione peroxidase (GSH-px) in renal cortex. Results The extent of RIF and the expression of CTGF,TGF-β1,α-SMA and ColⅢin renal cortex were significantly lower in sodium selenite group and benazepril group at day 7,14 and 21 after the op-eration compared with that in UUO group(P<0.05 or P<0.01). In sodium selenite group and benazepril group,the contents of SOD and GSH-px in renal cortex were higher significantly than those in UUO group at day 7,14 and 21 after the operation respectively(P<0.05),but the MDA in renal cortex was significantly decreased(P<0.05).There were no significant differences in the indexes between the two groups of sodium selenite and benazepril. The expres-sion of CTGF,TGF-β1,α-SMA,ColⅢand the extent of RIF were positively correlated to the level of MDA in UUO group(P<0.05,respectively),and negatively correlated to the level of SOD and GSH-Px(P<0.05,respectively). The expression of CTGF was positively correlated to the expression of α-SMA and ColⅢin UUO group(P<0.05).The expres-sion of CTGF,α-SMA and ColⅢwere positively correlated to RIF in UUO group(P<0.05).Conclusions Sodium sele-nite and benazepril can reduce the extent of RIF in rat model with unilateral ureteral obstruction.

OBJECTIVETo compare the therapeutic effects of prednisone combined with mycophenolate mofetil (MMF) versus cyclosporin A (CsA) in children with steroid-resistant nephrotic syndrome (SRNS).

METHODSThe clinical data of 164 SRNS children who were treated with prednisone combined with MMF or CsA between January 2004 and December 2013 were collected, and the clinical effect of prednisone combined with MMF (MMF group, 112 children) or CsA (CsA group, 52 children) was analyzed retrospectively.

RESULTSAt 1 month after treatment, the CsA group had a significantly higher remission rate than the MMF group (67.3% vs 42.9%; P<0.05). At 3 months after treatment, the CsA group also had a significantly higher remission rate than the MMF group (78.8% vs 63.3%; P<0.05). The 24-hour urinary protein excretion in both groups changed significantly with time (P<0.05) and differed significantly between the two groups (P<0.05). There were no serious adverse events in the two groups.

CONCLUSIONSPrednisone combined with MMF or CsA is effective and safe for the treatment of SRNS in children, and within 3 months of treatment, CsA has a better effect than MMF.

Background: The molecular prognostic markers and carcinogenesis of intrahepatic cholangiocarcinoma (ICC) have not been well documented. The purpose of this study was to investigate the prognostic value of the eyes absent homolog 4 (EYA4) gene in ICC and its biological effects on ICC growth in vitro and in vivo. Methods: One hundred twelve patients with ICC who underwent hepatectomy were enrolled in the study. EYA4 mRNA and EYA4 protein levels in ICC and adjacent non?tumoral tissues were evaluated using real?time quantitative polymerase chain reaction and immunohistochemical staining, respectively. EYA4 protein levels in ICC cells were determined using western blot analysis. The associations between EYA4 expression and clinicopathologic features of ICC were analyzed. To identify independent prognostic factors, univariate and multivariate analyses were performed. The biological effects of EYA4 on ICC cells were evaluated by establishing stable EYA4?overexpressing transfectants in vitro, and EYA4’s effects on tumor growth were evaluated by intra?tumoral injection of EYA4?expressing plasmids in a NOD/SCID murine model of xenograft tumors. Results: ICC tissues had signiifcantly lower EYA4 mRNA and protein levels compared with adjacent non?tumoral tis?sues (both P<0.001). Univariate and multivariate analyses showed that EYA4 protein level, tumor number, adjacent organ invasion, lymph node metastasis, and tumor differentiation were independent prognostic factors for disease?free survival and overall survival (all P<0.05). In vitro, EYA4 overexpression inhibited tumor cell growth, foci formation, and cell invasiveness. In vivo, intra?tumoral injection of EYA4?expressing plasmids signiifcantly inhibited ICC growth in the murine xenograft model compared with the control group (P<0.05). Conclusion: EYA4 gene functioned as a molecular prognostic marker in ICC, and its overexpression inhibited tumor growth in vitro and in vivo.

OBJECTIVETo study the clinical characteristics of children with an initial onset of IgA nephropathy with nephrotic syndrome and compare them with children with primary nephrotic syndrome, in order to provide a theoretical basis for the differential diagnosis of the two diseases.

METHODSFifty children diagnosed with an initial onset of IgA nephropathy with nephrotic syndrome were included in this study. Seventy-two children diagnosed with an initial onset of primary nephrotic syndrome served as the control group. The clinical and laboratory examination characteristics were compared between the two groups.

RESULTSThe IgA nephropathy group had significantly higher incidence rates of gross haematuria, microscopic haematuria, hypertension, acute kidney injury, low serum high-density lipoprotein cholesterol, anemia, low serum complement C4, steroid resistance, and nephritis-type nephrotic syndrome and a significantly lower incidence of elevated serum IgE compared with the control group (P<0.05). There were significant differences in serum creatinine, serum uric acid, serum total cholesterol, serum high-density lipoprotein cholesterol, serum IgE, serum complement C4, and hemoglobin levels between the IgA nephropathy and the control groups (P<0.05). The thresholds of serum IgE (<131.2 IU/mL) and high-density lipoprotein cholesterol (<1.35 mmol/L) were reference parameters in the differential diagnosis of IgA nephropathy with nephrotic syndrome and primary nephrotic syndrome.

CONCLUSIONSChildren with IgA nephropathy presenting nephrotic syndrome manifest mainly as nephritis type and steroid-resistant type in the clinical classification. Cinical manifestations accompanied by serum levels of high-density lipoprotein cholesterol and IgE are helpful for differential diagnosis of IgA nephropathy presenting nephrotic syndrome and primary nephrotic syndrome.
