Objective To explore the expression, correlation with clinicopathologic parameters, and clinical significance of MIS18 binding protein 1 (MIS18BP1) in bladder cancer. Methods TCGA and GEO databases were used to analyze the mRNA expression of MIS18BP1 in tumors and controls, and the results were verified via qRT-PCR. UALCAN online database was utilized in the analysis of the expression of MIS18BP1 and its correlation with clinicopathological parameters and the degree of immune cell infiltration. Immunohistochemistry was employed to analyze the expression of MIS18BP1 in bladder cancer and its relationship with clinicopathological features. The ROC curve was applied to evaluate the diagnostic value of MIS18BP1 mRNA in bladder cancer. Results Bioinformatics analysis and qRT-PCR results revealed the increased expression of MIS18BP1 mRNA in bladder cancer compared with that in the control group (P<0.05). Immunohistochemistry unveiled the significantly high positive rate of MIS18BP1 protein in bladder cancer (P<0.05) and its correlation with the clinical stage of tumors, depth of invasion, and lymph node metastasis (P<0.05). The immune infiltration analysis showed the association of MIS18BP1 with immune cell infiltration in bladder cancer. Conclusion The increased expression level of MIS18BP1 gene and protein in bladder cancer may regulate the development of bladder cancer by influencing immune cell infiltration.

Objective:To evaluate the relationship between hippocampal receptor-interacting protein kinase-1 (RIPK1) and nucleotide-binding oligomerization domain-like receptor containing pyrin domain 3 (NLRP3) inflammasomes in postoperative neurocognitive dysfunction of aged rats with chronic knee arthritis pain.Methods:Sixty-four healthy male Sprague-Dawley rats, aged 18 months, weighing 500-550 g, were divided into 4 groups ( n=16 each) using a random number table method: chronic knee arthritis pain group (group P), chronic knee arthritis pain+ operation group (group PS), RIPK1 inhibitor necrostatin-1+ chronic knee arthritis pain+ operation group (group NPS), and DMSO+ chronic knee arthritis pain+ operation group (group DPS). The knee arthritis model was prepared by intra-articular injection of monosodium iodoacetate (MIA) 1 mg into the left knee joint, and 12 weeks later exploratory laparotomy was performed under sevoflurane anesthesia. Necrostatin-1 6.25 mg/kg and the equal volume of DMSO were intraperitoneally injected at 1 h before operation in NPS group and DPS group, respectively. Thermal pain threshold was measured at 1 week before MIA injection and 6 and 12 weeks after MIA injection. Morris water maze test was used to evaluate the cognitive function at 7 days after surgery. Hippocampal tissues were obtained for microscopic examination of the pathological changes (after HE staining) and for determination of the expression of RIPK1, phosphorylated RIPK1 (p-RIPK1), NLRP3, activated cysteine-aspartic protease caspase-1 (cl-caspase-1), apoptosis-associated speck-like protein containing a CARD (ASC) (by Western blot) and contents of interleukin-1beta (IL-1β) and IL-18 (by enzyme-linked immunosorbent assay). Results:Thermal pain threshold was significantly decreased at 6 and 12 weeks after MIA injection as compared with that before injection ( P<0.05), and there was no significant difference in thermal pain threshold among the four groups ( P>0.05). Compared with P group, the escape latency was significantly prolonged, the time of staying at the original platform quadrant was shortened, the number of crossing the original platform was reduced, the expression of RIPK1, p-RIPK1, NLRP3, cl-caspase-1 and ASC was up-regulated, and the contents of IL-1β and IL-18 were increased ( P<0.05), and pathological changes of hippocampal neurons were marked in PS group, DPS group and NPS group. Compared with PS group and DPS group, the escape latency was significantly shortened, the time of staying at the original platform quadrant was prolonged, the number of crossing the original platform was increased, the expression of RIPK1, p-RIPK1, NLRP3, cl-caspase-1 and ASC was down-regulated, the contents of IL-1β and IL-18 were decreased ( P<0.05), and pathological changes of hippocampal neurons were significantly attenuated in NPS group. Conclusions:Postoperative hippocampal RIPK1 function is enhanced in aged rats with chronic knee arthritis pain, which then activates NLRP3 inflammasomes, triggering neuroinflammation, and this process may be involved in the mechanism of postoperative neurocognitive dysfunction.

In the past few decades, the global obesity population has been increasing, and still has an upward trend. With obesity, the risk of cardiovascular and cerebrovascular diseases has increased. It’s found that an increase in body mass index is associated with the occurrence of some cardiovascular and cerebrovascular diseases Hypertension and hyperlipidemia, as common chronic cardiovascular diseases, are particularly affected by obesity, which has attracted extensive attention in recent years. Moreover, the occurrence of hypertension and hyperlipidemia under the influence of obesity is significantly related, and their synergy can also cause a variety of cardiovascular and cerebrovascular diseases. However, there is still less work to study these three factors at the same time. Therefore, on the basis of summarizing the molecular mechanisms of obesity affecting hypertension and hyperlipidemia, this paper summarizes the relevant molecular mechanisms of hypertension and hyperlipidemia under the influence of obesity, and points out the co-acting molecules, providing a reference for future research on cardiovascular and cerebrovascular diseases.

Objective To investigate the expression of serum vascular endothelial growth factor receptor-1(VEGFR-1)and macrophage inflammatory protein-3α(MIP-3α)in patients with endometriosis(EMs)patients and the predictive value of their combined detection for postoperative recurrence in EMs patients.Methods A total of 114 patients with EMs who underwent laparoscopic surgery in Maternal and Child Care Hospital of Qinhuangdao from April 2019 to June 2021 were selected as the observation group,while 114 healthy medical checkups of women of gestational age who had their medical checkups in the hospital were selected as the control group during the same period.Enzyme-linked immunosorbent assay(ELISA)was used to determine the serum levels of VEGFR-1 and MIP-3α in the patients.According to the postoperative period of 2 years,they were divided into the recurrence group(n=78)and the non-recurrence group(n=36).Multivariate logistic regression analysis was used to analyze influencing factors of postoperative recurrence in patients with EMs.The predictive value of the combined serum VEGFR-1 and MIP-3α test for postoperative recurrence in patients with EMs was analyzed by using the receiver operating characteristic curve(ROC)curve.Results Compared with the control group,the levels of VEGFR-1 in the observation group(116.25±48.57 pg/ml vs 92.43±25.37 pg/ml)and MIP-3α(19.25±5.24 pg/ml vs 13.67±4.28 pg/ml)were elevated,and the differences were significant(t=4.641,8.806,all P＜0.05).The level of VEGFR-1(104.22±5.78 pg/ml,118.60±6.56 pg/ml,138.55±7.85 pg/ml)and the level of MIP-3α(15.37±1.15 pg/ml,19.28±2.12 pg/ml,25.42±2.56 pg/ml)in mild,moderate and severe EMs patients were increased successively,and the differences were significant(F=147.757,133.654,all P＜0.001).The percentage of the presence of palpable nodules in the posterior fornix,r-AFS staging(stage Ⅲ～Ⅳ)in the recurrence group was greater than those in the non-recurrence group(x2=15.139,10.310,all P＜0.05),and the percentage of the recurrence group with postoperative medication for 6 months or more was lower than that of the non-recurrence group(x2=15.016,P＜0.001),and the differences were statistically significant,respectively.Multivariate logistic regression analysis showed that serum VEGFR-1,MIP-3α,the presence of palpable nodules in the posterior fornix and r-AFS staging were risk factors for postoperative recurrence of EMs(all P＜0.05),while postoperative medication for 6 months or more was a protective factor(P＜0.05).The ROC curves showed that the area under the curve(AUC)of the combination of serum VEGFR-1 and MIP-3αpredicted postoperative EMs for postoperative recurrence was the largest(0.929),and its sensitivity and specificity were 85.90％and 86.11％,respectively.Conclusion VEGFR-1 and MIP-3α expression was elevated in the serum of patients with EMs.The efficacy of their combined detection in predicting recurrence after EMs could be better.

Objective To investigate the impact of esketamine hydrochloride in combination with ultrasound-guided transverse thoracic muscle plane block on stress response and inflammatory levels in patients undergoing cardiac valve replacement under general anesthesia.Methods A total of 120 patients who underwent elective extra-corporeal circulation-supported median open heart valve replacement were selected and randomly assigned into four groups using the random number table method:general anesthesia alone(Group G),general anesthesia with intrave-nous administration of esketamine(Group E),general anesthesia with transverse thoracic plane block(Group T),and esketamine combined with transverse thoracic muscle plane block(Group ET);each group consisted of 30 cases.Patients in group E and group ET received a continuous infusion of esketamine hydrochloride injection at a rate of 0.2 mg/kg-1?h-1 until the completion of the surgical procedure,while patients in group G and group T received an equivalent volume of saline solution until the completion of the surgical procedure.After the induction of general anesthesia,patients in group T and group ET underwent ultrasound-guided bilateral transverse thoracic muscle plane block,while patients in group G and group E did not receive any specific intervention.All four groups received identical protocols for anesthesia induction and maintenance,with self-controlled intravenous analgesic pumps administered to all patients postoperatively.The following time points were recorded:1 day prior to surgery(T0),pre-induction of anesthesia(T1),1 minute post-tracheal intubation(T2),1 minute post-median sternotomy(T3),1 minute prior to initiation of cardiopulmonary circulation(T4),1 minute after cessation of cardiopulmonary circula-tion(T5),1 minute after completion of surgery(T6),1 day post-surgery(T7),2 days post-surgery(T8),and 3 days post-surgery(T9).Mean Arterial Pressure(MAP)and Heart Rate(HR)were continuously monitored from T1 to T6.The levels of blood glucose and lactate were measured and recorded at T1,T4 to T6.The levels of White Blood Cells(WBC)and C-Reactive Protein(CRP)were assessed at T0,as well as at T7 to T9.The occurrence of postoperative adverse reactions was documented in all four groups.Results(1)Comparison of hemodynamics among the four groups:Compared with group G,there was a significant decrease in MAP and HR at T3 in group T(P<0.05).At the T5 time point,MAP was lower in group ET compared to group E,while HR was higher in group ET compared to group T(P<0.05).(2)The lactate and blood glucose levels of the four patient groups after extracorporeal circulation transfer were higher than those at the T1 time point(P<0.05).Patients in group E had lower lactate values at the T5 time point and lower blood glucose values at the T6 time point compared to group G(P<0.05).Additionally,patients in group E exhibited lower lactate and blood glucose values at both the T5 and T6 time points compared to those in group T(P<0.05).(3)Compared to T0,the levels of white blood cells(WBC)and C-reactive protein(CRP)were increased in all four groups after surgery(P<0.05).At the T7 time point,the WBC levels in group E and group T were significantly lower than those in group G(P<0.05).Furthermore,compared to group E and group T,the level of WBC in group ET was significantly lower at T7,while the level of CRP was significantly lower at T8(P<0.05).(4)There were no significant differences observed in postoperative adverse reactions among the four groups(P>0.05).Conclusion Combining low-dose esketamine hydrochloride with transverse thoracic muscle plane block under general anesthesia during open heart valve replacement surgery can effectively stabilize the patient's hemodynamics,mitigate perioperative stress response and postoperative inflammation levels,thereby demonstrating significant clini-cal utility.

Objective To explore the blood group changes of two acute myeloid leukemia patients with suspected O type,and their relationship with the therapeutic effect.Methods Serological analysis of ABO blood group of patients was carried out by microcolumn gel method,tube method and absorption-elution test,ABO blood group genotyping was per-formed by microfluidic chip method.Exons E2 to E7 of ABO gene were amplified by PCR and sequenced by Sanger method.Results The forward typing of two cases were both O type,but the reverse typing were both A type.The absorption-elution test results all showed detection of antigen A.ABO gene phenotype of the two cases were both A,with genotyping results as A102/A102 and A102/O01,respectively.Sequencing results showed that SNP sites of ABO blood group were 467T/T,261G/delG and 467C/T,respectively.In one case,the intensity of anti-A agglutination reaction changed significantly from weak to strong with the progress of treatment.Conclusion For clinical samples of acute myeloid leukemia patients with ABO for-ward and reverse typing discrepancy and suspected O type,the result of reverse typing should be valued,and absorption-e-lution test should be performed to further confirm the ABO blood type combining the genetic test results,so as to develop ap-propriate blood transfusion strategies for patients.

OBJECTIVE: To assess the value of Improved Mayo Endoscopic Score (IMES) for evaluation of treatment efficacy for active ulcerative colitis (UC). METHODS: We retrospectively analyzed the clinical and endoscopic data of 103 patients diagnosed with active UC in Beijing Tsinghua Changgung Hospital from January, 2015 to December, 2020. The severity of endoscopic lesions was determined by Mayo Endoscopic Score and the Ulcerative Colitis Endoscopic Index of Severity (UCEIS), and the area of the endoscopic lesions was evaluated based on the Montreal classification system. The IMES was established by combining the MES with the Montreal classification. RESULTS: Univariate analysis suggested that young patients (<40 years old), patients with extensive disease type (E3), patients with high endoscopic scores (MES=3, UCEIS>4, and IMES>4), and patients receiving advanced drug therapy (with systemic hormones, immunosuppressants, immunomodulators, and biological agents, etc.) had lower clinical and endoscopic remission rates. COX survival analysis showed that IMES≤4 was an independent risk factor for clinical and endoscopic remission. ROC curve indicated that the predictive value of IMSE≤4 for clinical and endoscopic remission (AUC=0.7793 and 0.7095, respectively; P<0.01) was better than that of Montreal (AUC=0.7357 and 0.6847, respectively; P<0.01), MES=2 (AUC=0.6671 and 0.5929, respectively; P<0.01), and UCEIS≤4 (AUC=0.6823 and 0.6459, respectively; P<0.01); IMES=5 had a better predictive value for patients with active UC undergoing colectomy tham E3 and MES=3. CONCLUSION IMES has good value in evaluating treatment efficacy for active UC.

【Objective】 To investigate the practice and benefit of national standardized management of type 2 diabetes in Yulin City. 【Methods】 We recruited the adult type 2 diabetes patients who sought medical help at our hospital from May 2020 to October 2022 as subjects. We collected their basic information (sex and age); measured height, weight, waist and hip circumference, and blood pressure; calculated body mass index (BMI); and detected blood glucose, c-peptide, HbA1c, biomarkers, urinary microalbumin, sensory nerve conduction velocity of lower limbs, ABI, and subcutaneous and visceral fat at the time of MMC recruited and the end of six months. T test and Mann-Whitney U rank sum test were used for measurement data and χ² test or Fisher’s exact probability method for counting data to analyze the data. 【Results】 After 6 months, the levels of fasting blood glucose, postprandial blood glucose, HbA1c, and visceral and subcutaneous fat in all the patients decreased, but the level of fasting c-peptide increased compared with the baseline (all P<0.05). Secondly, compared with the baseline, the control rate of HbA1c (35.21% vs. 13.71% ) and the comprehensive control rate (13.97% vs. 7.26% ) were both significantly increased at six months (P<0.05). Thirdly, after 6 months, the levels of fasting blood glucose, postprandial blood glucose, HbA1c, TG, TC, and UA were decreased more, while the fasting c-peptide and postprandial c-peptide were increased more in the patients of the HbA1c standard group (HbA1c<7% ) than those of the non-standard group. 【Conclusion】 The multiple benefits of blood glucose, blood lipid, uric acid and islet function can be achieved by taking type 2 diabetes patients into MMC. Meanwhile, the rates of HbA1c control and comprehensively reaching the standard are significantly increased. Therefore, MMC can explore a new way for the management of type 2 diabetic patients in this area.

【Objective】 To investigate the clinicopathological features and prognosis of clear cell papillary renal cell carcinoma (CCPRCC). 【Methods】 The clinicopathological and follow-up data of 40 CCPRCC patients treated during Jun. 2011 and Oct.2021 were retrospectively analyzed. The prognosis was compared with that of 40 cases of clear cell renal cell carcinoma (ccRCC) and 19 cases of papillary renal cell carcinoma (PRCC) treated in the same period. Survival analysis was performed by Log-rank test and Kaplan-Meier survival curves were plotted. 【Results】 Among the 40 patients, 28 were male and 12 were female, aged 31-84 years; 38 cases had unilateral and 2 cases had bilateral tumors; 3 cases had multifocal lesions. All patients received surgery. The maximum diameter of the masses ranged from 3.0 to 95.0 mm, with an average of (27.6±18.1) mm. Pathological grade was Fuhrman 1-2 in all cases. Immunohistochemical tests were positive for CK7 and CA-IX. During the follow-up of 5-129 (average 56) months, 1 case died after bone metastasis, 2 had ipsilateral recurrence, and 1 developed primary esophageal cancer. CCPRCC patients had a significantly better prognosis than CCRCC (P<0.001) and PRCC (P=0.005) patients, while there was no significant difference in the prognosis between CCRCC and PRCC patients (P=0.93). 【Conclusions】 CCPRCC has low malignancy. The diagnosis relies on characteristic pathological and immunohistochemical features. Surgery is an effective treatment. CCPRCC has a better overall prognosis than CCRCC and PRCC.
