Discuss the method of acute hyperuricemia replication on rats. Method Hypoxanthine was administered via stomach, uricase inhibitor was injected intraperitoneally, then inspect the uric acid in serum at different periods of time. Results When we combined hypoxanthine with uricase inhibitor, the uric acid in serum of different dose groups was higher than control group after 3 hours(P

Objective To study the expression and clinical significance of anty-apoptosis protein BAG-1 in non-small cell lung cancer(NSCLC),and its relationship with cell apoptosis and expression of Bcl-2 protein. Methods Immunohisto chemistry streptavidin-peroxidase conjugated (SP)method was used to examine the expression of BAG-1protein and Bcl-2 protein,and terminal deoxynucleotidyl transferase mediated UTP nick end labeling(TUNEL) method was used to examine the apoptosis index in 54 cases of NSCLC.The expression of BAG-1 protein in 20 cases of normal bronchus mucosa tissue also be detected as control. Results Express positive rate of BAG-1 protein in NSCLC is 74.07%,obviously higher than that in normal bronchus mucosa tissue(positive rate is 5%).In cases of NSCLC,the expression of BAG-1 protein has not correlation with the age,gender,pathologic classification,but have closed correlation with lymph node metastasis,degree of differentiation,pTNM stage(P

ObjectiveStudy the effects of mitral valve replacement using video-assisted thorascoscopy compared with median sternotomy mitral valve replacement.MethodsBetween October 2003 and October 2011,72 cases suffer from mitral valve disease underwent video-assisted thorascoscopic mitral valve replacement,74 cases underwent median sternotomy procedure.CPB time,cross clamp time,ventilation time,drainage,ICU stay time and hospital stay time of the two groups were compared.Results It was longer that CPB time and cross clamp time in video-assisted thoracospic group than those of median sternotomy group.There was statistically significant difference.However there was no statistically significant differentce in ventilation time and ICU stay time between two groups.Drainage of video-assisted thoracospic group was less than median sternotomy group.And there was statistically significant difference.ConclusionAs long as strictly a good indication,mitral valve surgery can routinely be performed with video-assisted thoracospic.

Objective To investigate the effect of free toe transplantation in finger reconstruction.Methods Free toe transplantations were performed in 164 patients (185 fingers) suffering from finger defection.There were 134 males and 30 females,aged at 12-83 years [mean (44.8 ± 11.2)years].Finger deletion severity was classified as grade Ⅰ in one case,grade Ⅱ in 18,grade Ⅲ in 23,grade Ⅳ in 49,grade Ⅴ in 54,and grade Ⅵ in 19.According to Gilbert standards,dorsal metatarsal arteries were classified as type Ⅰ in 68 cases,type Ⅱ in 84,and type Ⅲ in 12.Survival ratio of the transplanted fingers and hand function rehabilitation were observed.Results The transplanted toe survived in 160 cases (173 fingers).They composed of all the cases of grade Ⅰ-Ⅴ finger deletion and 15 cases of grade Ⅵ finger deletion; all the cases of type Ⅰ dorsal metatarsal arteries,83 cases of type Ⅱ dorsal metatarsal arteries and nine case of type Ⅲ dorsal metatarsal arteries.Transplantation failed in four cases (12 fingers) of grade Ⅵ finger defection including one case of Gilbert Ⅱ dorsal metatarsal arteries and three cases of Gilbert Ⅱ dorsal metatarsal arteries.Postoperative results were excellent in 110 cases and good in 50.Conclusions Toe transplantation is helpful to restore the finger shape and function and the outcome is satisfactory.Anatomic deformation of dorsal metatarsal arteries is the main cause for the failure of finger reconstruction.

Clinical data of a case of occult pulmonary actinomycosis with foreign body admitted to Shenzhen Children′s Hospital were retrospectively analyzed, and the relevant literatures were retrieved and reviewed.A female patient aged 6 years and 9 months planned to receive hematopoietic stem cell transplantation due to thalassemia.During the plain chest CT examination before the transplantation, flakes of shadows were examined in the right lower lung.The child had no clinical symptoms or pulmonary signs.The granulation tissue hyperplasia of the right lower lobe was detected by tracheoscopy, which was harvested for examination under tracheoscopy, and actinomycete infection was confirmed.Several bone fragments were found wrapped inside the granulation.After 6 months of treatment with Amoxicillin and Clavulanate potassium, the tracheoscopic manifestations and chest CT were improved.Pulmonary actinomycosis is a rare pulmonary infectious disease, which is much rarer in children than adults, manifesting as an insidious onset and atypical clinical manifestations.However, foreign bodies in children′s airway are common, which is favorable to infection.In clinical detection of actinomycete infection, the cause of infection should be concerned to prevent misdiagnosis and mistreatment.

Objective:To establish a predictive model and investigate its value in evaluating short-term prognosis of patients with hepatitis B virus related acute-on-chronic liver failure (HBV-ACLF).Methods:Patients with HBV-ACLF admitted to Tianjin Second People's Hospital and Beijing Youan Hospital, Capital Medical University from May 2015 to October 2018 were enrolled. The data of gender, age, laboratory markers at admission, model for end-stage liver disease (MELD) score and clinical complications were collected for analysis. According to the prognosis on 12-week, patients were divided into survival group and death group. Univariate analysis and binary Logistic regression analysis were used to test the risk factors for short-term prognosis of the patients with HBV-ACLF, and a prediction model was established. The accuracy of each index and the established model were verified by the receiver operating characteristic (ROC) curve.Results:A total of 148 patients with HBV-ACLF were enrolled in the study, 91 cases survived while 57 cases died during the 12-week period. The age, total bilirubin (TBIL), neutrophil percentage (NEUT%), hepatitis B surface antigen (HBsAg), MELD score of death group were higher than those of survival group [age (years old): 50.00 (44.50, 55.00) vs. 43.00 (34.00, 53.00), TBIL (μmol/L): 310.30 (240.70, 405.70) vs. 266.40 (184.20, 360.20), NEUT%: (74.52±13.05)% vs. (66.64±12.35)%, lg HBsAg (kU/L): 3.72 (3.29, 3.92) vs. 2.97 (2.49, 3.78), MELD score: 24.27 (19.71, 27.40) vs. 21.88 (18.83, 24.38), all P < 0.05], while albumin (ALB), total cholesterol (CHO), prothrombin activity (PTA) and alpha-fetoprotein (AFP) were lower than those of survival group [ALB (g/L): 29.80 (27.05, 31.05) vs. 30.80 (28.00, 33.90), CHO (mmol/L): 1.98 (1.50, 2.38) vs. 2.49 (2.05, 3.01), PTA: (30.37±7.09)% vs. (32.94±6.03)%, AFP (μg/L): 21.54 (9.28, 51.54) vs. 66.16 (24.50, 152.80), all P < 0.05]. Logistic regression analysis showed that NEUT%, HBsAg and AFP were independent risk factors for short-term prognosis of patients with HBV-ACLF [odds ratio ( OR) was 77.843, 1.439, 0.995, respectively, all P < 0.05]. According to the results of regression analysis, the NHA-ACLF model (NEUT%+HBsAg+AFP) was established. The formula was logit (NHA-ACLF) = -5.441+5.688×NEUT%+0.430×lg HBsAg-0.005×AFP. The area under the ROC curve (AUC) of the NHA-ACLF model for pred HBV-ACLF patients was 0.790, which was better than NEUT% (AUC = 0.696), lg HBsAg (AUC = 0.670), AFP (AUC = 0.703) and MELD score (AUC = 0.640). When the cut-off value of NHA-ACLF model score was 0.459, the sensitivity was 73.7%, and the specificity was 79.1%. Conclusions:NEUT%, HBsAg and AFP are independent predictive indicator for short-term prognosis in patients with HBV-ACLF. Compared with MELD score, the risk assessment model NHA-ACLF has a greater value in predicting the short-term prognosis of patients with HBV-ACLF.

Liver failure belongs to the category of jaundice and yellow plague in the traditional Chinese medicine. It has something in common with the etiology and pathogenesis of jaundice. In Synopsis of Prescriptions of the Golden Chamber, the theories, methods, prescriptions and drugs for jaundice are systemically explained, and the related therapeutic principles and methods are proposed, that have profound influence on the treatment of jaundice for later generations. From the point of view upon the treatment of jaundice in Synopsis of Prescriptions of the Golden Chamber, the treatment of liver failure is discussed in this article. The author thinks that the "dampness, heat and blood stasis" are the pathological bases of jaundice, but the heat phenomenon is more obvious in the course of the disease, and at later stage"deficiency" is significant; the basic principle of the treatment of liver failure should first comply with clearing away heat and promoting diuresis, using the drugs heavily for heat-clearing and detoxifying to block the disease as the main line especially at the beginning stage, drugs for activating blood circulation and removing blood stasis are applied from the beginning to the end of the treatment, and in the mean time, regulation of spleen and stomach and tonification of spleen and kidney should be paid attention to especially at the later stage. The application and skill of making Yinchenhao decoction for treatment of jaundice is also important.

Hepatitis D virus (HDV) infection causes the most severe form of viral hepatitis with rapid progression to cirrhosis, hepatic decompensation, and hepatocellular carcinoma. Although discovered > 40 years ago, little attention has been paid to this pathogen from both scientific and public communities. However, effectively combating hepatitis D requires advanced scientific knowledge and joint efforts from multi-stakeholders. In this review, we emphasized the recent advances in HDV virology, epidemiology, clinical feature, treatment, and prevention. We not only highlighted the remaining challenges but also the opportunities that can move the field forward.

Background/Aims: Non-alcoholic fatty liver disease (NAFLD) is closely associated with metabolic dysfunction. Among the multiple factors, genetic variation acts as important modifiers. Klotho, an enzyme encoded by the klotho (KL) gene in human, has been implicated in the pathogenesis of metabolic dysfunctions. However, the impact of variants in KL on NAFLD risk remains poorly understood. The aim of this study was to investigate the impact of KL rs495392 C>A polymorphism on the histological severity of NAFLD. Methods: We evaluated the impact of the KL rs495392 polymorphism on liver histology in 531 Chinese with NAFLD and replicated that in the population-based Rotterdam Study cohort. The interactions between the rs495392, vitamin D, and patatin-like phospholipase domain containing 3 (PNPLA3) rs738409 polymorphism were also analyzed. Results: Carriage of the rs495392 A allele had a protective effect on steatosis severity (odds ratio [OR], 0.61; 95% confidence interval [CI], 0.42–0.89; P=0.010) in Chinese patients. After adjustment for potential confounders, the A allele remained significant with a protective effect (OR, 0.66; 95% CI, 0.45–0.98; P=0.040). The effect on hepatic steatosis was confirmed in the Rotterdam Study cohort. Additional analysis showed the association between serum vitamin D levels and NAFLD specifically in rs495392 A allele carriers, but not in non-carriers. Moreover, we found that the rs495392 A allele attenuated the detrimental impact of PNPLA3 rs738409 G allele on the risk of severe hepatic steatosis. Conclusions The KL rs495392 polymorphism has a protective effect against hepatic steatosis in patients with NAFLD.
