Objective To investigate the clinical and pathologic features of primary hepatic carcinoma(PHC) associated with hepatitis B virus,HBV). Methods 200 cases of the patients with PHC were diagnosed by histopathologic examination and surgery. The history of HBV infection, its infective patterns and abnomal liver function were obtained from the medical history, and the tests of liver function and HBV five markers. The pathologic features of PHC associated with HBV were determined by analysis of histopathologic changes and views of surgery. Results The markers of HBV were positive in 181 out of 200 cases with PHC, and the positive rate of HBV infection was 90.5%. The postitive rate of HBsAg, anti-HBe and anti-HBc was the highest among the five markers of HBV (50.83%). The positive rate of HBsAg and HBeAg and anti-HBc was only 4.97%. The PHC patients without history of HBV infection and asymptomatic carriers of HBV accounted for 61.33% and 6.63%, respectively. The cases with cured hepatitis and no relapse accounted for 8.29%. The cases with chronic hepatitis B and with liver cirrhosis accounted for 22.10% and 1.66%, respectively. Liver functions were slightly abnomal in approximately one-half patients with PHC. Histopathologic features were as following: HCC accounted for 91.95%, and nodular type, macro-type and small hepatic carcinomas accounted for 55.25%, 30.94% and 13.81%,respectively. The distributions of PHC were mainly in right lobe of liver. The incidence of venous cancer embolism was 12.71%. The incidence of liver cirrhosis was 83.32%. Conclusions ⑴There was relationship between HBV and PHC. The main infective pattern of HBV was the positive HBsAg, anti-HBe and anti-HBc;⑵Pathologic lesion of liver was hidden after infection of HBV;⑶The incidence of active cirrhosis was high; and ⑷There were many pathologic features in patients with PHC associated with HBV.

Objective To investigate the expression of monocyte chemoattractant protein-1(MCP-1)and CCR2 in peripheral blood and pleural fluid of tuberculous pleurisy patients.Methods Flow cytometry was used to detect the expression of CCR2 in the peripheral blood mononuclear cell and pleural fluid cell of tuberculous pleurisy patients;ELISA was used to detect the content of MCP-1 in serum and pleural fluid.Results MCP-1 in surem and pleural fluid and CCR2 in the peripheral blood mononuclear cell and pleural fluid cell of tuberculous pleurisy patients was significantly higher than that of the healthy normal controls[MCP-1:(340.8±220.8)and(9.0±3.8)ng/L,P＜0.01;CCR2(18.2±10.1)%and(6.9±3.5)%,P＜0.05];Both MCP-1 and CCR2 were detected in pleural fluid and both of them were positivley correlated(r=0.227,P＜0.05).Conclusion The expression of MCP-1 and CCR2 in peripheral blood of tuberculous pleurisy patient are significantly elevated which are significance molecule participating in the pathogenesis of tuberculous pleurisy.

Objective To report a family with lipoid proteinosis (LP) from Shandong province and to analyze mutations in the extracellular matrix protein 1 (ECM1) gene in this family.Methods Eight members in a threegeneration family with LP were clinically investigated,and two patients were identified to suffer from LP,including the proband (Ⅲ 1) and her mother (Ⅱ 2).Both of the patients presented with papules on the palpebral margin,short and thick lingual frenum,and hoarseness.Indirect laryngoscopy showed infiltrating and thickening of the vocal cord.Pathological examination of lesions on the palpebral margin and laryngeal mucosa revealed deposits of hyaline-like material in the dermis,which was strongly positive for periodic acid-Schiff (PAS) staining and resistant to diastase digestion.The pathological diagnosis was LP.Blood samples were collected from all the family members and 100 ethnically matched,unrelated and unaffected Chinese human controls followed by DNA extraction.PCR and sequencing were performed to detect the ECM1 gene,and nested PCR followed by agarose gel electrophoresis to analyze mutations in the coding region of the ECM1 gene.Results Both of the two patients were compound heterozygotes.Three missense mutations,incluing p.P169T,p.A44T and p.R392W,were found in the ECM1 gene of the affected mother,with p.P169T in one allele and p.A44T as well as p.R392W in the other.The girl patient inheried the missence mutation p.P169T from her mother and a synonymous mutation c.879G ＞ A from her father (Ⅱ 1).Nested PCR showed that the c.978G ＞ A mutation generated a splice-acceptor site AG,which leaded to a splicing defect.Conclusion A novel synonymous splice-acceptor site mutation c.879G ＞ A in the ECM1 gene is identified in the family with LP.

Objective To observe the effects of Qutantongluo decoction on the expression of TGF-β1 in renal tissue of diabetic nephropathy(DN) rats,which can help to understand the mechanism of action.Methods The rats models of diabetic nephropathy were established by injecting with streptozotocin intraperi-toneally.All Wistar rats were randomly divided into 6 groups:the normal control group,the model control group,Benazepril Hydrochloridec group ( 1 mg/kg ·d-1 ),Qutantongluo decoction low dose group (3 g/kg ·d-1 ),Qutantongluo decoction median dose group (4.5 g/kg · d-1 ),and Qutantongluo decoction high dose group (6 g/kg · d-1 ).Rats in the normal control group and the model control group were given celiac perfusion of distilled water once at the same time and dose.All the rats were gavaged once daily for 8 weeks.The expression of TGF-β1 at the level of gene and protein in renal tissue were tested by immunohistochemistry and RT-PCR methods.Results Compared with the model control group(2.79±0.22),the expression of TGF-β1 at the level of protein in renal tissue of Benazepril Hydrochloridec group (1.55 ±0.12)and the Qutantongluo decoction low dose group ( 1.54± 0.16),Qutantongluo decoction median dose group (1.49 ± 0.17),Qutantongluo decoction high dose group(l.39±0.25) decreased significantly (P＜0.05).Compared with the model control group (0.35±0.07),the expression of TGF-β1 mRNA in renal tissue of Benazepril Hydrochloridec group(0.35± 0.07)and the Qutantongluo decoction low dose group(0.39±0.03),Qutantongluo decoction median dose group (0.35± 0.06),Qutantongluo decoction high dose group (0.32± 0.07) decreased significantly (P＜0.05).Conclusion Qutantongluo decoction can down regulate the expression of TGF-β1 in kidney,which may be one of the mechanisms of Qutantongluo decoction effectiveness in clinical treatment of diabetic nephropathies.

[Summary] Interleukin-2 receptor antagonist (IL-2Ra,ie,basiliximab and daclizumab),a new antibody agent,is widely employed in lowering the risk of acute rejection after organ transplantation,but it meanwhile causes increasing concerns on the effect it exerts on glucose metabolism in transplant recipients,and so far the exact effect still remains controversial.New onset diabetes after transplantation (NODAT) is one of the most influential metabolic complications affecting graft survival and patients' long-term outcomes.Some of the current researches indicate that IL2Ra may improve glucose metabolism in the transplant recipients,some show just the opposite,yet others show no effects.Hence further investigations focusing this aspect are needed.

Objective To evaluate the status of abnormal glucose metabolism in patients being alive over 3years after liver transplantation and discuss the possible mechanism of post-transplant diabetes mellitus ( PTDM ).Methods In this study, the clinical data of patients with liver transplantation were collected from April 2001 to December 2008. Patients with diabetes mellitus before operation and those who had died and failed to appear during follow-up were exluded. 199 patients living over 3 years after liver transplantation were follow-up. The prevalence of PTDM was evaluated according to fasting plasma glucose(FPG). Among those without diabetes according to FPG,32patients underwent 75 g oral glucose tolerance test (OGTT) , and fasting and 2 h plasma glucose and insulin were determined. 32 patients were divided into three groups [normal, impaired glucose regulation ( IGR ) , and PTDM groups], proportion of PTDM and homeostasis model assessment ( HOMA ) index were calculated. Results In patients alive over 3 years after liver transplantation, the prevalence of PTDM was 34.67% according to FPG. The OGTT result showed that the proportion of PTDM was 9.38%, IGR, including impaired fasting glucose(IFG) and impaired glucose tolerance ( IGT ) , was 56. 25% , while 34. 37% remained normal. The homeostasis model assessment β cell function index( HOMA-β ) decreased progressively from normal group, IGR group to PTDM group,and that in PTDM group was significantly lower than those in normal and IGR group( P＜0.01 ). IGR group had the highest homeostasis model assessment for insulin resistance (HOMA-IR) and PTDM group the next, and HOMA-IR in IGR group was significantly higher than normal group. Conclusion In patients alive over 3 years after liver transplantation, the prevalence of PTDM reached 44.05%. Insulin resistance existed during early period of impaired glucose regulation, while the degeneration of β cell progressed with the worsening of impaired glucose regulation.

Objective To study the effect of Pinus yunnanensis on acute alcoholic liver injury in rats and explore its mechanism. Methods A model of acute alcoholic liver injury in mice was prepared by alcohol. The mice were randomly divided into normal control group, model group, positive control group, Pinus yunnanensis low-, medium-and high-dose groups. Mice in the medicine group were given the corresponding medicine by gavage once a day for 7 days. After the last three hours of intragastric administration, the liver and spleen index, ALT, AST and GSH in serum, SOD, MDA and NO in liver homogenates were measured. Histopathological changes of liver were observed by HE staining. Results Compared with model group, Pinecone of Pinus unnanensis high-, medium- and low-dose groups could significantly reduce the liver index in mice (P<0.01), and high dose groups could significantly reduce the number of spleen (P<0.01); The contents of AST in the medium- and high-dose groups significantly decreased (P<0.01) and the GSH activity significantly increased (P<0.05, P<0.01). There was no significant difference in serum ALT level, SOD activity, GSH activity and NO content in the liver tissues of Pinus yunnanensis groups (P>0.05). HE staining results showed that, the damage of liver tissue in mice of Pinus yunnanensis was significantly improved compared with the model group. Conclusion Pinus yunnanensis has protective effects on acute alcoholic liver injury in mice.

Objective To summarize the experience of emergency treatment and cosmetic repair of facial trauma.Methods The clinical materials of 584 wounds from 291 cases of facial trauma,recruited in hospital from January 2010 to August 2012,were summed up retrospectively.The principles of medical aesthetics and plastic and cosmetic surgery were followed.A high pressure douching technique was employed to carry out thorough debridement,but occasion of the debridement did not emphasize with intensive attention.A wound without skin and soft tissue defect was sutured accurately according to tissue zonation with a new suture technique,and the needle distance or side distance was limited in 0.2 cm to 0.3 cm.Otherwise,the wound was repaired by full-thickness skin graft or various flaps according to the repair principle ofrather near than further,rather simple than complicated.Attention was paid to rehabilitation care.Results After debridement,328 wounds were sutured directly,147 wounds were repaired by full-thickness skin grafting and 109 wounds by various flaps.A total of 571 wounds healed on the first stage,and the healing rate reached 97.8％.The wounds were in satisfactory apposition and without obvious cicatrix.Five senses did not appear in malposition and deformity.The other 13 wounds did not heal because of bad taking of skin grafts and flaps or wound splitting.Among them,4 wounds were repaired by second operation,and 9 wounds healed by changing dressings.By means of rehabilitation care,scar hyperplasia and pigmentation appeared slightly in those 13 wounds.A total of 454 wounds from 217 cases were followed up.The results showed good appearance and slight cicatrix hyperplasia,a pigmentation in different degree appeared in 11 wounds covered by skin grafting.In addition,eyebrow excalation,auricle excalation or total lose appeared in 12 cases.Conclusion During treating emergency cases of facial injuries,if an idea cosmetic repair of traumais followed,the theory of aesthetics and the techniques of plastic and cosmetic surgery are fully used,a multiple-discipline cooperation is brought into full play,and a prompt and accurate treatment is put into practice,the aim of cosmetic repair would come true.
