Objective To investigate the expression of cysteine-rich intestinal protein 1(CRIP1),STIP1 ho-mology and U-box protein 1(STUB1)in cancer tissues of patients with hepatocellular carcinoma and their clinical prognostic significance.Methods From February 2018 to February 2020,112 patients with hepatocel-lular carcinoma were selected as the study objects.The expression of CRIP1 and STUB1 in cancer tissues and adjacent tissues of patients with hepatocellular carcinoma was detected by immunohistochemistry.To analyze the relationship between the expression of CRIP1 and STUB1 and their clinicopathological features in hepato-cellular carcinoma patients.Kaplan-Meier survival analysis of the effects of CRIP1 and STUB1 expression on the prognosis of patients with hepatocellular carcinoma.COX regression analysis was performed to analyze the prognostic factors of hepatocellular carcinoma.Results The positive rate of CRIP1 in cancer tissues of pa-tients with hepatocellular carcinoma was 62.50％(70/112),which was significantly higher than that in adja-cent tissues[7.14％(8/112)],the difference was statistically significant(x2=76.652,P＜0.05).The positive rate of STUB1 in cancer tissues of patients with hepatocellular carcinoma was 26.23％(32/112),significantly lower than that in adjacent tissues[82.14％(92/112)],and the difference was statistically significant(x2=73.284,P＜0.05).The expression of CRIP1 was negatively correlated with STUB1 in cancer tissues(r=-0.678,P＜0.001).There were significant differences in the positive rates of CRIP1 and STUB1 in hepato-cellular carcinoma patients with different TNM stages,histological grades and maximum tumor diameter(P＜0.05).The 3-year cumulative survival rate of CRIP1 positive group was significantly lower than that of CRIP1 negative group,with statistical significance(Log-rank x2=29.601,P＜0.001).The 3-year cumulative survival rate of STUB1 negative group was significantly lower than that of STUB1 positive group,with statistical sig-nificance(Log-rank x2=13.590,P＜0.001).TNM stage Ⅱ-Ⅲ,histological grade Ⅲ,maximum tumor diam-eter＞5 cm,CRIP1 positive and STUB1 negative were independent risk factors for prognosis of hepatocellular carcinoma patients.Conclusion CRIP1 expression is up-regulated and STUB1 expression is down-regulated in hepatocellular carcinoma tissues.The prognosis of patients with hepatocellular carcinoma can be evaluated clinically based on the expression of CRIP1 and STUB1 in hepatocellular carcinoma tissues.

Objective:To analyse the differences of related genes between serum alpha-fetoprotein (AFP) positive gastric cancer and AFP negative gastric cancer, and the relationship between related genes and prognosis of serum AFP positive gastric cancer.Methods:A total of 1 144 gastric cancer patients undergoing surgery at the 940th Hospital , Joint Logistic Support Force, People's Liberation Army from Jan 2013 to Dec 2018 were retrospectively analyzed. Of them, 47 cases were of AFP positive gastric cancer, and 47 serum AFP negative case were obtained by proper matching method.Results:Forty-seven patients with serum AFP positive gastric cancer, accounting for 4.1% of all gastric cancer patients during the same period. The prognosis of serum AFP negative gastric cancer is better than that of serum AFP positive gastric cancer. The 1-, 3- and 5-year cumulative survival rates were 95.6% vs. 63.8%, 48.9% vs. 23.4% and 26.7% vs. 14.9%, respectively. There were statistical differences in the immunohistochemistry of AFP, HER2, VEGF, GPC3, SALL4, P53 and Ki67 between the two groups ( χ2=67.758, P<0.001; χ2=4.004, P=0.044; χ2=19.299, P<0.001; χ2=5.232, P=0.022; χ2=6.359, P=0.012; χ2=6.224, P=0.013; χ2=5.232, P=0.022). The more co-positive expressions of AFP, GPC3, VEGF and SALL4, the more likely they were to affect pTNM stage, vascular invasion and liver metastasis ( χ2=5.328, P=0.021; P=0.013; χ2=5.887, P=0.015; χ2=3.923, P=0.048). Univariate and multivariate survival analysis of serum AFP positive gastric cancer showed:AFP, GPC3, VEGF and SALL4 were risk factors for AFP positive gastric cancer ( HR=3.700, P=0.036; HR=4.237, P=0.003; HR=3.916, P=0.004; HR=3.412, P=0.001). Conclusions:Serum AFP positive gastric cancer is a rare and highly invasive special type of gastric cancer. AFP, GPC3, VEGF and SALL4 are overexpressed in serum AFP positive gastric cancer, which is correlated with tumor stage, vascular invasion and liver metastasis. The final diagnosis of serum AFP positive gastric cancer still needs immunohistochemical examination. Preoperative serum AFP level is an important basis for AFP positive gastric cancer screening and AFP immunohistochemical examination.

Objective:To investigate the effect of cholesterol-modified prognostic nutritional index (cPNI) on postoperative long-term prognosis of the borderline resectable pancreatic cancer (BRPC).Methods:Clinical data of 173 patients with BRPC admitted to the Department of Hepatobiliary and Pancreaticosplenic Surgery, Beijing Chaoyang Hospital, Capital Medical University from January 2011 to September 2023 were retrospectively analyzed, including 90 males and 83 females, aged (61.7±9.8) years. The receiver operating curve (ROC) of preoperative cPNI predicting 1-year postoperative survival was drawn and the optimal cut-off value in predicting 1-year survival was 77.36. Patients were divided into low cPNI ( n=83, cPNI≤77.36) and high cPNI group ( n=90, cPNI>77.36). Kaplan-Meier method was used for survival analysis, log-rank test was used for univariate analysis, and Cox proportion hazard model was used for multivariate analysis to reveal the effect of cPNI on postoperative long-term survival in patients with BRPC. Results:The cumulative survival rates at 1, 2 and 3 years after surgery in low cPNI group and high cPNI group were 70.6%, 40.3%, 21.8%, and 48.3%, 21.5%, 9.5%, respectively ( χ2=8.49, P=0.004). Univariate analysis showed that preoperative cPNI, length of portal vein invasion, tumor differentiation degree, tumor TNM stage, tumor diameter, lymph node metastasis, and postoperative chemotherapy were correlated with long-term survival of BRPC patients (all P<0.05). Multivariate analysis showed that BRPC patients with preoperative cPNI >77.36 ( HR=1.452, 95% CI: 1.026-2.053, P=0.035) had a increased risk of postoperative death, while patients with length of portal venous invasion >3.0 cm, poorer tumor differentiation, lymph node metastasis and no postoperative chemotherapy had an increased risk of postoperative death. Conclusion:Preoperative cPNI >77.36 is a risk factor for long-term survival in BRPC patients.

Objective:To explore the expression level and clinicopathological characteristics of 14-3-3θ protein in distal cholangiocarcinoma tissues, and further analyze the long-term prognosis of patients with different expression levels.Methods:A retrospective cohort study was conducted to collect and analyze the clinical data of 135 patients with distal cholangiocarcinoma who underwent surgical resection at the Department of Hepatobiliary Surgery, Beijing Chaoyang Hospital Affiliated to Capital Medical University from January 2015 to December 2021, including 86 males and 49 females.(65.1±10.1) years old. Immunohistochemistry was used to detect the expression level of 14-3-3θ protein in cholangiocarcinoma tissue. The postoperative pathological sections of patients were evaluated based on the immune response score(IRS). The optimal cutoff value was determined through the receiver operating characteristic(ROC) curve was 3.5. Currently, the area under the curve was 0.741, the sensitivity was 73.5%, and the specificity was 71.3%. The patients were divided into two groups: IRS<4 was the 14-3-3θ low expression group( n=81), IRS≥4 was the 14-3-3θ high expression group( n=54). After surgery, the patient′s survival status was followed up through a combination of outpatient review and telephone follow-up. Normally distributed measurement data were expressed as mean ± standard deviation( ± s), and comparisons between groups were made using the t test; non-normally distributed measurement data were expressed as M( Q1, Q3), and comparisons between groups were made using the rank sum test. The chi-square test was used to compare enumeration data between groups. Results:The preoperative CA19-9 and lymph node metastasis in the 14-3-3θ low expression group were 44.3(20.8, 132.2) U/mL and 28 cases respectively. The preoperative CA19-9 and lymph node metastasis in the 14-3-3θ high expression group were 82.3(43.4, 396.9) U/mL and 32 cases respectively. The difference between the two groups was statistically significant( P<0.05). All patients had regular postoperative telephone calls or return to the hospital for follow-up. The median postoperative survival time of the 14-3-3θ low-expression group was 36 months. The 1-, 2-, and 3-year survival rates after surgery were 88.9%, 66.5%, and 66.5%, respectively. 49.4%, the median survival time after surgery in the 14-3-3θ high expression group was 13 months, and the 1, 2, and 3-year survival rates after surgery were 53.7%, 23.3%, and 13.3% respectively. The difference between the two groups was statistically significant. significance( P<0.01). Cox proportional hazard model performed multivariate analysis, CA19-9>37 U/mL ( RR=1.970, 95% CI: 1.186-3.272, P=0.009), lymph node metastasis( RR=1.681, 95% CI: 1.035-2.729, P=0.036) and 14-3-3θ staining intensity≥4 ( RR=2.438, 95% CI: 1.546-3.845, P<0.001) have worse long-term prognosis. Conclusions:The expression level of 14-3-3θ protein is related to CA19-9 and lymph node metastasis in distal cholangiocarcinoma. A high expression of 14-3-3θ protein indicates poor long-term prognosis in patients with extrahepatic cholangiocarcinoma.

Objective:To evaluate the predictive value of prognostic nutritional index (PNI) for survival after radical resection in patients with distal cholangiocarcinoma.Methods:The clinical data of 160 patients with distal cholangiocarcinoma undergoing radical pancreatoduodenectomy in Beijing Chaoyang Hospital Affiliated to Capital Medical University from September 2011 to March 2022 were retrospectively analyzed, including 97 males and 63 females, aged (65.58±9.22) years old. The optimal cut-off value of PNI for predicting postoperative survival was 42.275 determined by the receiver operating characteristic curve. Patients were divided into the low PNI group ( n=79, PNI<42.275) and high PNI group ( n=81, PNI≥42.275). The survival status of patients were followed up by outpatient clinic or telephone review. Survival analysis was performed using the Kaplan-Meier method and the log-rank test. Factors with P<0.1 in the univariate analysis were included in the Cox proportional hazards model for multivariate analysis to screen the prognostic factors. Results:There were statistically significant differences in the preoperative albumin, total bilirubin, lymphocytes counts between the two group (all P<0.05). The postoperative median survival time of the low PNI group was 17 months, with cumulative 1, 3 and 5-year survival rates of 62.0%, 25.0% and 16.2%, respectively. The postoperative median survival time of the high PNI group was 23 months, with cumulative 1, 3 and 5-year survival rates of 84.0%, 46.4% and 40.4%, respectively. There was a significant difference between the two groups ( P<0.001). PNI score<42.275 ( HR=1.040, 95% CI: 1.011-1.071, P=0.008), CA19-9>37 U/ml ( HR=1.620, 95% CI: 1.046-2.509, P=0.031), venous invasion ( HR=1.809, 95% CI: 1.013-3.230, P=0.045), lymph node metastasis ( HR=1.956, 95% CI: 1.300-2.969, P=0.001), tumor diameter >2 cm ( HR=1.534, 95% CI: 1.011-2.328, P=0.044), without postoperative adjuvant chemotherapy ( HR=2.828, 95% CI: 1.291-6.195, P=0.009) had a greater risk of poor survival after radical resection. Conclusion:PNI score could be an influencing factor and serve as a predicting tool for the survival after radical resection in patients with distal cholangiocarci-noma.

Von Hippel-Lindau (VHL) disease is a benign or malignant tumor syndrome which involves multiple systems and organs.Recently,a patient was diagnosed and hospitalized with an initial clinical symptom of pancreatic multiple cystic space-occupying.Multidisciplinary examination and consultation confirmed that there were hemangioblastomas in cerebella,spinal cord and retina,but with no clinical symptoms;therefore,it was diagnosed as VHL disease.According to previous case reports,only a few single cases revealed lesions in so many parts of the central nervous system with typical imaging manifestations.We present an overview and aim to improve the diagnosis of VHL disease with the initial clinical symptom of pancreatic lesions.

Objective To understand the prevalence,treatment and influence factors of hypertension in maintenance hemodialysis (MHD) patients in Anhui Province.Methods A total of 2724 adult patients on MHD from January 1st 2014 to March 31st 2014 in 26 hospitals of southern,northern and central Anhui Province were investigated.Their demographic characteristics,primary disease,complications,medications,dialysis and laboratory examination were explored.The prevalence treatment rate and control rate of hypertension were analyzed.Associated factors for controlling hypertension [systolic blood pressure (SBP) ＜ 140 mmHg and diastolic blood pressure (DBP) ＜ 90 mmHg] were assessed by logistic regression analysis.Results (1) The prevalence of hypertension in the hemodialysis patients was 87.0％.Their treatment rate and control rate were 93.2％ and 23.9％ respectively.The average of SBP was (145.90±21.18) mmHg,and the DBP on average was (83.60± 12.21) mmHg.The most commonly used anti-hypertensive drug is calcium channel blocker (88.2％).Over one third (45.7％) of patients were treated with two kinds of anti-hypertensive drug,26.2％ with 1 kind,21.7％ with 3 kinds,and 6.4％ with 4 kinds or more.(2) Compared with non-hypertension patients,patients with hypertension have older age,higher body mass index (BMI),phosphorus,SBP and DBP,as well as lower hemoglobin and Kt/V (all P ＜ 0.05).(3) The multivariate logistic regression analysis showed that Ca ＞ 2.50 mmol/L (OR=2.084,95％CI 1.008-4.307,P=0.047) positively correlated with controlling hypertension,while smoke (OR=0.594,95％CI 0.356-0.911,P=0.046) and BMI 18.5 ～ 23.9 kg/m2 (OR=0.516,95％CI 0.293-0.907,P=0.022) negatively correlated with it.Conclusions High prevalence yet low control rate of hypertension in MHD patients in Anhui Province were observed.Hypocalcemia may be a protective factor for hypertension control,while smoke and BMI may be risk factors for it.

BACKGROUND:Recently, the effects of human umbilical cord mesenchymal stem cel s (hUCMSCs) and placenta-derived mesenchymal stem cel s (PDMSCs) on treatment of acute graft versus host disease (aGVHD) have been confirmed in some in vitro studies or animal models. But there are stil no reports comparing the therapeutic effects of these two cel types. OBJECTIVE:To compare the immunosuppressive function of hUCMSCs and PDMSCs in vitro or in a mouse aGVHD model. METHODS:(1) In vitro experiment. Human peripheral blood mononuclear cel s (PBMCs) were isolated and divided into four groups:PBMCs cultured alone, PBMCs stimulated with phytohaemagglutinin (PHA), PHA stimulated-PBMCs cocultured with hUCMSCs, PHA stimulated-PBMCs cocultured with PDMSCs. After 5 days, PBMCs proliferation and interferon-γlevel in cel supernatant were measured. (2) In vivo experiment. Fifty-seven BABL/C(H-2d) mice exposed to 8.5 Gy irradiation were randomly divided into five groups:only saline injection group, syngeneic bone marrow transplantation group, al ogeneic bone marrow transplantation group, aGVHD group, hUCMSCs treatment group, PDMSCs treatment group. The clinical aGVHD score, histopathology of skin, liver, and smal intestine, and survival time were analyzed at days 11, 14, 21 after transplantation. RESULTS AND CONCLUSION:(1) In vitro test:compared with the hUCMSCs, PDMSCs had stronger anti-inflammatory function. (2) In vivo test:The clinical scores on acute graft versus host disease were significantly lower in the hUCMSCs and PDMSCs treatment groups than that in the aGVHD group (P<0.05). The survival rates of mice were significantly increased in the hUCMSCs and PDMSCs treatment groups compared to the aGVHD group (P<0.05). Evident skin lesions were not found in al groups. Although smal intestine mucosal lesions were found in al groups, the damage level seemed similar. Notably, significant difference was found in the liver that multifocal necrosis and a large number of inflammatory cel s were seen in the aGVHD group, but less necrosis and inflammatory cel s in the hUCMSC and PDMSC treatment groups. In conclusion, hUCMSC and PDMSC are comparably effective in the treatment of aGVHD in mice.

Objective To explore the feasibility of mechanical chest compression to establish a rat model of car?diopulmonary resuscitation ( CPR) . Methods 4?month old healthy male Sprague Dawley rats were randomly divided into control group ( n=6 ) and model group ( n=10 ) . After induction of anaesthesia with 10% chloraldurate ( 3 ml/kg, i. p. ) , tracheal intubation and left femoral artery cannulation were performed. Under electrocardiographic and artery blood pressure monitoring, tracheal obstruction ( TO) was performed to rats in model group. At 2 min after the cardiac arrest ( CA) occurred, CPRs were administered to the rats using a self?made animal chest compressor, which provided chest?com?pression at a rate of 200 bpm. Results Shortly after TO, rats in the model group had respiratory arrest, cyanosis and ar?rhythmia. Electrocardiography indicated that CA occurred within 4-5 min, with a decreased artery systolic blood pressure ( <40 mmHg) and a zero pulse pressure. Return of spontaneous circulation ( ROSC) after the CPR was successfully a?chieved in 8 rats (80%), with a transient reperfusion arrhythmia. Finally, 60% of the rats (n=6) recovered to con?sciousness and survived for 24 hrs. The serum biochemical analysis indicated that there were electrolyte disturbances, aci?dosis, impaired renal functions and increased myocardial enzyme spectrum. Pathological examination revealed cardiac rhab? domyolysis, no?reflow phenomenon in renal glomeruli, decrease of neurons and pulmonary congestion in the model group rats. Conclusions Mechanical chest compression can provide minimal cardiac output for the requirement of CPR incardiac arrestin rats. It is feasible to establish rat CPR model with the mechanical chest compression.
