Chinese Journal of Hepatobiliary Surgery 2016;22(9):642-645
Post-hepatitis cirrhosis (PHC),which results from either hepatitis B virus (HBV) or hepatitis C virus (HCV) infection,and its associated with hemodynamic changes may cause the spleen to become functionally hyperactive-a condition known as hypersplenism.Hypersplenism is associated with anemia,leukopenia,thrombocytopenia and splenomegaly.There are several effective methods to treat hypersplenism with the development of medical technology and the main purpose is the remission of hypersplenism,reducing the portal hypertension and decreasing the risk of hemorrhage.However,complete splenectomy or partial treatment of the hyperactive spleen is still controversial all over the world.This may be caused by the lack of the knowledge on the pathophysiological characteristics and clinical significance of treating hypersplenism.This review is a comprehensive discussion on the recent research which investigates hypersplenism caused by PHC.

Pancreatic necrosis (IPN) is a serious complication of acute pancreatitis (AP), with a mortality reported to be as great as 32.0%. At present, it is considered that patients with proven or suspected infected necrotizing pancreatitis, invasive intervention (i.e. percutaneous catheter drainage, endoscopic transluminal drainage/ necrosectomy, minimally invasive or open necrosectomy) should be delayed where possible until at least 4 weeks after initial presentation to allow the collection to become 'walled-off'. With the development of endoscopic technology, endoscopic transmural (stomach or duodenum) drainage and necrosectomy has been recommended as one of the preferred methods for walled-off necrosis. This article introduces the diagnosis and evaluation of the walled-off necrosis ; the indications, operation procedures, postoperative evaluation and management of postoperative complications of endoscopic transmural drainage and necrosectomy. At last, the research progress of endoscopic drainage and debridement in recent years was introduced.

Objective To investigate whether lipopolysaccharide (LPS) can induce vascular endothelial cell growth factor (VEGF) expression in microglia regulated by hypoxia inducible factor-1α(HIF-1α). Methods The cultured BV2 cells were divided into four groups:control group, LPS (100 μg/L) simulated group, LPS (100 μg/L)+LPS antagonist (LRS, 200 μg/L) intervened group and LPS (100 μg/L)+HIF-1αinhibitors FM19G11 (10 mmol/L) intervened group. Immunofluorescence staining, Western blotting and ELISA were used to detect the expressions of VEGF and HIF-1α. Results Compared with the control group, the VEGF expression level was obvious high in LPS simulated group (P<0.05). LRS inhibited this effect of LPS (P<0.05). The HIF-1αlevel was increased in LPS simulated group at 8 h post-injury (P<0.05). FM19G11, the inhibitor of HIF-1αreduced the expression of VEGF induced by LPS (P<0.05). Conclusion LPS can up-regulate the expression of VEGF by HIF-1α.

Abstract: Objective To explore the early diagnostic value of peripheral blood peroxisome proliferator-activated receptor γ (PPARγ) combined with γ-interferon (IFN-γ) release assay (IGRA) in the diagnosis of pulmonary tuberculosis in patients with end-stage renal disease (ESRD), and to provide reference for clinical diagnosis and treatment. Methods From January 2019 to December 2021, 70 ESRD patients with suspicious symptoms of pulmonary tuberculosis were treated at Hebei Chest Hospital were selected as the research objects. According to the examination results, they were divided into ESRD group (40 cases) and ESRD complicated by pulmonary tuberculosis (40 cases, comorbidity group). In addition, 40 cases with pulmonary tuberculosis were used as the PTB group. All three groups of patients underwent IGRA test, and the peripheral blood PPARγ level was detected by enzyme-linked immunosorbent assay, and the diagnostic value of PPARγ combined with IGRA test for ESRD patients with pulmonary tuberculosis was explored. Results The expression level of PPARγ and IFN-γ content in the PTB group and the comorbidity group were obviously higher than those in the ESRD group (P<0.05), while the differences in PPARγ expression level and IFN-γ content between the PTB and comorbidity groups were not statistically significant (P>0.05). The ROC curve showed that the areas under the curve (AUC) of PPARγ and IGRA in the diagnosis of end-stage renal disease combined with tuberculosis were 0.823 (95%CI: 0.722-0.925) and 0.773 (95%CI: 0.662-0.883), respectively, and the AUC of combined detection was 0.928 (95%CI: 0.871-0.984), which was better than that of PPARγ and IGRA alone (Z/P=2.057/0.039, 2.843/0.005). The Kappa values of serum PPARγ and IGRA test compared with the clinical gold standard results in the diagnosis of ESRD complicated with pulmonary tuberculosis were 0.557 and 0.444 (P<0.05). The combined screening of ESRD with pulmonary tuberculosis was consistent with the clinical gold standard (Kappa=0.661, P<0.05). Among the 30 ESRD patients complicated with pulmonary tuberculosis, the sensitivity of PPARγ combined with IGRA test in diagnosis of ESRD complicated with pulmonary tuberculosis was 93.33% (28/30), which was higher than 70.00% (21/30) of PPARγ and 66.67% (20/30) of IGRA test alone (P<0.05). Conclusions Peripheral blood PPARγ and IGRA tests have certain diagnostic value for ESRD complicated with tuberculosis, and the combined detection of the two can improve the sensitivity and reduce the rate of missed diagnosis, which is worthy of clinical promotion.

Authors carried out the survey for human paragonimiasis in Ko-Hoong County, Chun-Nam Province, Korea from July to September 1964 by the use of intradermal screening test with Veronal buffered saline antigen. Eight myuns (village) out of 13 myuns of this county were selected for the survey, regarding balanced selection. The number of 2,916 primary school children of high class and 764 residents of all age groups in these areas were examined (total 3,680; male 1,961; female 1,719). The following results were obtained in this survey. As a whole, 20.1 per cent of the examiners showed positive reaction, with sexual difference of 20.9 per cent in male and 19.1 per cent in female. In regional differences of positive rate, the highest rate(50.1 per cent) was showed at Po-Doo myun and lowest rate(3.6 per cent) was showed at Do-Yang myun. In age group, the highest positive rate was showed in 16 to 20 age group (46.7 per cent). In regional comparison of paragonimiasis infectivity of whole nation (province and county), Ko-Hoong County as nearly same as the Hea-Nam County, Chun-Nam Province follows next of Cheju Province, the highest prevalance area of paragonimiasis in Korea, in concentration of prevalence of paragonimiasis.
