Downhill esophageal varices (DEV) is a rare cause of upper gastrointestinal bleeding. It is different from ascending esophageal varices caused by portal hypertension, and caused by obstruction of the superior vena cava. It can be secondary to an indwelling central venous catheter. It is very dangerous when DEV is complicated with upper gastrointestinal bleeding,and there is no unified treatment strategy at present. We report a case of hemodialysis patient with left upper limb swelling for 6 months and intermittent hematemesis for 3 months. Combined with gastroscopy and CT venography, the patient was considered to have DEV rupture and hemorrhage. The patient was discharged after comprehensive treatment including closure of internal arteriovenous fistula, ligation of bleeding points of esophageal varices, recanalization of superior vena cava, and "culprit" vein embolization. There was no recurrence after half a year of follow-up. This case is helpful for clinicians to improve the recognition on this disease and explore the experience of diagnosis and treatment.

Objective To explore the correlation between helicobacter pylori(Hp)infection and inflam-matory factors,as well as its association with the progression of liver fibrosis in patients with metabolically associ-ated fatty liver disease(MAFLD)and type 2 diabetes mellitus(T2DM).Methods A total of 300 patients diag-nosed with MAFLD and T2DM who were admitted to the Hepatology Department of Hebei Hospital of Traditional Chinese Medicine between April 2023 and March 2024 were recruited.Based on Hp infection status,these patients were classified into an Hp-positive group and an Hp-negative group.Subsequently,the clinical data,inflammatory factors,and liver fibrosis indices of the two groups were comprehensively compared.Furthermore,the patients in the Hp-positive group were randomly assigned to an intervention group and a control group.The intervention group received standard Hp eradication therapy,whereas the control group was administered placebo therapy.Pearson correlation analysis was employed to investigate the associations among Hp infection,inflammatory factors,and liver fibrosis indices.Binary logistic regression analysis was utilized to identify the independent risk factors influencing the progression of liver fibrosis.Results In both the Hp-positive and Hp-negative groups,parameters including age,fasting blood glucose(FPG),glycosylated hemoglobin(HbA1c),total bilirubin(TBIL),direct bilirubin(DBIL),indirect bilirubin(IBIL),tumor necrosis factor-α(TNF-α),and interleukin-6(IL-6),along with C-reactive protein(CRP)and liver stiffness measurement(LSM),were meticulously measured.Statistical analysis revealed that the differences in these parameters between the two groups were significant(P<0.05).Specifically,within the experimental setup,the levels of TNF-α,IL-6,CRP,and LSM in the intervention group were notably lower than those in the control group(P<0.05).Pearson correlation analysis was employed to explore the relation-ships among variables,and the results indicated a positive correlation between the Hp detection value(DPM)and the levels of TNF-α,IL-6,CRP,and LSM(P<0.05).Furthermore,binary logistic regression analysis was con-ducted to identify independent risk factors.The findings demonstrated that positive Hp infection,elevated TNF-α,elevated IL-6,and elevated CRP were independent risk factors for the progression of liver fibrosis(P<0.05).To evaluate the diagnostic performance,the receiver operating characteristic(ROC)curve analysis was carried out.The areas under the curve(AUC)for HP infection,TNF-α,IL-6,and CRP were 0.800,0.786,0.769,and 0.783,respectively.These values were significantly lower than the AUC of 0.896 obtained from the combined detection(P<0.05).Conclusions In MAFLD patients with T2DM,DPM is closely associated with inflammatory factors(such as TNF-α,IL-6,and CRP)and the advancement of liver fibrosis.The combined detection of these factors holds significant value in predicting the progression of liver fibrosis.It can offer a reliable foundation for the clinical assessment of the risk of liver fibrosis progression.

Objective To investigate the correlation between red cell volume distribution width (RDW) and the mortality rate of acute respiratory distress syndrome (ARDS) patients after renal transplantation. Methods Clinical data of 106 ARDS patients undergoing renal transplantation were retrospectively analyzed. According to RDW, all patients were assigned into the normal (≤15.0%, n=68) and increasing RDW groups (>15.0%, n=38). Baseline data and the incidence of adverse events were statistically compared between two groups. Kaplan-Meier survival curve was adopted to compare the 50 d-mortality rate between two groups. Cox's proportional hazards regression model was utilized to identify the risk factors of the mortality of ARDS patients. Results Among 106 patients, the 50 d-mortality rate was calculated as 43.4% (46/106). The sequential organ failure assessment (SOFA) score, serum creatinine, hemoglobin and platelet count significantly differed between two groups (all P<0.05). In the increasing RDW group, the 50 d-mortality rate and the incidence of infectious shock were significantly higher than those in the normal RDW group (both P<0.05). Kaplan-Meier survival curve demonstrated that the 50 d-mortality rate significantly differed between two groups (P<0.01). Cox's proportional hazards regression model univariate analysis revealed that hemoglobin level<100 g/L, serum creatinine>133 μmol/L, platelet count<100×109/L, severe ARDS and RDW>15.0% were the potential risk factors of the 50 d-mortality rate in ARDS patients (all P<0.05). Multivariate analysis demonstrated that severe ARDS [odd ratio (OR)=12.77, 95%confidence interval (CI) 11.63-15.39, P<0.001] and RDW>15.0% (OR=2.01, 95%CI 1.02-3.94, P<0.043) were the independent risk factors of the 50 d-mortality rate in ARDS patients. Conclusions RDW elevation is correlated with the severity of disease and 50 d-mortality rate in ARDS patients following renal transplantation. RDW can serve as a clinical parameter to predict the prognosis of ARDS patients after renal transplantation.

OBJECTIVE: To evaluate the recovery of patients with end-stage renal disease (ESRD) receiving kidney transplant from cardiac death donors, and to assess graft survival in China from this type of donor. METHODS: A total of 48 cases of patients with ESRD have received the kidneys from cardiac death donors in our hospital between February 2010 and March 2012. We retrospectively analyzed data on the preoperative and postoperative serum creatinine concentrations, on the survival of recipients and allografts with a view to investigating prognoses after this type of kidney transplant. RESULTS: Primary non-function (PNF) did not occur in any of the 48 recipients. Delayed graft function (DGF) occurred in 18 of 48 (37.5%) of kidneys from cardiac death donors, but the occurrence of DGF did not adversely influence patient's survival (P=0.098) or graft survival (P=0.447). Seven of 48 (14.6%) recipients lost their graft. Over a median follow-up period of 8 months (range 0.5-23 months), 39 of 41(95.1%) recipients' graft function had fully recovered. The actuarial graft and patient's survival rates at 1, 3, 6 and 12 months after transplantation were 95.7%, 93.0%, 90.0%, 87.5%, and 100%, 94.9%, 90%, 87.5%, respectively. CONCLUSION As the legislation of donation after brain death (DBD) has not been ratified in China, the use of kidneys from cardiac death donors might be an effective way to increase the number of kidneys available for transplantation here. Our experience indicates good short- and mid-term outcomes with transplants from cardiac death donors.

Objective To investigate the epidemiological characteristics and factors of hemorrhagic fever with renal syndrome (HFRS) during 1958 to 2007 in Fuyang.Methods Descriptive study method was used to analyze the epidemiological characteristics of hemorrhagic fever with renal syndrome.The incidence peak of hemorrhagic fever with renal syndrome was computed by using rotundity distribution.The correlation was analyzed between incidence and virus index by Pearson correlation.Results 40 002 HFRS cases was reported during 1958 to 2007 in Fuyang and 2381 cases were dead.The average incidence and fatality rate of HFRS were 11.99 per 100 thousand and 5.95 percent respectively.Eight counties all had cases.Yingshang county had the highest cases and Jieshou city had the highest fatality rate.Since 1958,there're 4 incidence peak in Fuyang.The period of high incidence was during November to January of next year and the peak of incidence rate was on December 13.Indoor density and field density of mouse were 9.84 percent and 7.91 percent respectively.Virus rate of indoor and field of mouse were 9.21 percent and 6.99 percent respectively.During 1984 to 2007,the correlation coefficient between virus index and incidence was 0.58.In room brown mouse was the most before 2000,but then house mouse become the most.In open country heavy line Japanese fieldmouse is the most mouse all the time.Conclusions In Fuyang,the focus of HFRS is exist widely.Density and virus rate of mouse will directly affect the incidence.So surveillance among mouse should be strengthened.

Chronic myeloid leukemia (CML) appears an ideal and exciting immunological target. Novel and rational immunotherapy may therefore play an important adjuvant role in the treatment of CML patients. Peptides derived from the BCR-ABL fusion region have been shown to be immunogenic and are able to stimulate the production of BCR-ABL-specific T cell lines and clones. In this study, A 280 bp multiple epitope region of BCR-ABL fusion antigen was designed and synthesized. This region contains three BCR-ABL antigen epitopes which can bind to HLA-A2, HLA-A3 and HLA-DR11 molecules, respectively, and epitopes of cholera toxin B (CTB) and tetanus toxoid (TT) which are able to elicit vigorous T cell responses. The fusion antigen gene has highly been expressed in E. coli and the purified fusion protein reserved satisfied activity and antigenicity. The results of this investigation provided a basis for further research on the developing specific T cell immunotherapy of CML.
