Journal of Forensic Medicine 2001;17(1):28-29,31
220 cases of tympani membrane perforated were summarized retrospectively. The tympani membrane perforated of injury was different from otitis media's because they had marked or extreme marked difference in sex, age, ear distinction, shape, position, size, degree of hearing damaged, time of healing, cause of perforating and adhesive substance. This difference was relative to mechanism of tympani membrane perforated. The distinction gist of two sorts of tympani membrane perforated was expounded through comparison and analysis. It would be of great value to clinical forensic medical examination.

Objective To investigate the characteristics and prevention of deep fungal infection (DFI) complicated by severe acute pancreatitis (SAP). Methods Clinical data of 135 SAP cases admitted from Oct. 1998 to Oct. 2009 were studied, the prevention and management of SAP with DFI ( 32cases) were investigated, among them there were 19 males and 13 females. Results Seven patients (21.9%) died of these 32 cases. The SAP patients with DFI were of more critical condition, longer course and having to stay in ICU about (21±6) d, most needed surgical debridement, on long-term indwelling catheters, intubation and mechanical ventilation, parenteral nutrition, long-term use of broad-spectrum antibiotics. These patients remained in the hospital for about (78 ± 14) d. Conclusions DFI is a common complication in SAP cases causing a significant mortality hence necessitating comprehensive prevention and control measures such as proper handling of the original disease, aseptic operation, prophylactic antibiotics and antifungal agents, which can reduce the incidence and mortality of SAP with DFI.

Objective:To investigate the value of anti-hexokinase1 antibodies (anti-HK-1) and anti-kelch-like 1 antibodies (anti-KLHL12) antibody in evaluating ursodeoxycholic acid (UDCA) response in patients with primary biliary cholangitis (PBC).Methods:112 PBC patients who had been treated with UDCA for more than 12 months with relatively complete clinical data were analyzed. Serum was collected and the expression of anti-mitochondrial antibody (AMA), anti-HK-1 and anti-KLHL12 antibodies were detected by ELISA. The response to UDCA was based on Paris standard. According to the expression of new antibodies, the patients were divided into the new antibody positive group and negative group. In addition, PBC related baseline indicators were collected, and Spearman correlation analysis was used to study the correlation between antibody expression and baseline indicators in PBC patients.Results:Positivity of anti-HK1 and anti-KLHL12 antibody in AMA-positive PBC patients were 44.7% and 41.2% respectively. Positivity of anti-HK1 and anti-KLHL12 antibodies in AMA negative PBC patients were 33.3% and 22.2%. Anti-HK1 positive patients had higher serum levels of Alaninetransaminase (ALP), aspartate aminotransferase, (AST), γ-glutamyl transpeptidase (γ-GT) and total bilirubin (TBIL) compared with anti-HK1 negative patients, with statistical significant differences ( P<0.05). Notably, correlation analysis showed significantly positive correlation between anti-HK1 antibody expression and ALP, γ-GT and TBIL serum levels ( r=0.735, P<0.05; r=0.332, P<0.05; r=0.491, ( r=0.466, P<0.05). The UDCA response rate in anti-HK-1 antibody positive group was lower than that of the negative group (36.2% vs 60%; P<0.05). Conclusion:Anti-HK-1 and anti-KLHL12 antibody can help to diagnose PBC, and the expression of anti-HK-1 antibody is correlated with the severity of PBC, which could help to predict the reaction of PBC patients to UDCA.

ObjectiveTo compare liver pathology changes of patients with Budd-Chiari syndrome (BCS) and intrahepatic portal hypertension (IPH) after portosystemic shunt surgery. MethodsFrom January 2010 to December 2011,liverbiopsy was taken during shunt surgery (9 BCS patients,4 IPH patients),and 6-9 months after surgery on follow-up.Collagen type Ⅳ ( Col Ⅳ ),procollagen m (PC Ⅲ ),matrix metalloproteinase (MMP-1),tissue inhibitors of metalloproteinase(TIMP-1) were tested using SABC (immuonohistochemistry) method,and HE staining to observe the morphology of liver tissue.Free portal vein pressure before and after shunt was measured. ResultsIn BCS group,Col Ⅳ,PC 1Ⅲ and TIMP-1expression downregulated after surgery (127 ±15) vs.(137 ±16),t =4.896,P-0.013; (115.2 ± 10.6) vs.(127.3±9.5),t=4.877,P=0.003; (119.2±11.3) vs.(131.2±l9.6),t=2.841,P=0.023.MMP-1expression did not change ( P > 0.05 ),while MMP-1/TIMP-1was not significantly correlated with liver fibrosis (0.95 ±0.16) vs.(0.98 ±0.15),t =-0.710,P =0.504.In IPH group,the expression of Col Ⅳ,PCⅢ,MMP-1,and MMP-1/TIMP-1did not change significantly after surgery (P >0.05).Compared with that in IPH group the expression of PC Ⅲ,Col Ⅳ and TIMP-1downregulated significantly in BCSgroup (127±15) vs.(150 ±12),U=3.000,P=0.038; (115.2 ±10.6) vs.(128.1±2.8),U=2.000,P=0.023; (119.2 ± 11.3) vs.(131.4 ±2.5),U=3.000,P =0.038.By HE staining in BCS group there was significant intrahepatic congestion which alleviated after surgery.While in PHT group liver pathology did not change significantly after surgery.FPP in BCS and IPH patients significantly decreased after shunt surgery (25 ±8) vs.(41±8) cmH20,t=17.816,P=0.000;(31±8) vs.(45 ±9) cmH20,t =5.745,P =0.010 ). Drop of FPP of BCS group plays a key role in reversal of liver fibrosis.ConclusionsIn BCS group liver pathology improved after shunt surgery probably by removing the intrahepatic obstruction,but in IPH group liver pathology remained unchanged after shunt.
