Objective To evaluate the efficacy of comprehensive treatment for liver cancer recurrence and metastasis after liver transplantation, and investigate the risk factors affecting the lifespan of patients with liver cancer recurrence and metastasis. Methods Of 29 patients with liver cancer recurrence and metastasis after liver transplantation, 11 patients in the comprehensive treatment group were treated by TACE, microwave coagulation, radiotherapy or hepatectomy, and the remaining 18 patients were classified into chemotherapy group. The differences in efficacy between the 2 treatment modalities were compared, and the factors influencing the patients' lifespan were analyzed. Results Compared with patients in the chemotherapy group, patients in the comprehensive treatment group had significantly longer lifespan after liver cancer recurrence and metastasis (t = 5. 617, P < 0.01). TNM staging, pathological classification, time of postoperative recurrence and metastasis and treatment method were the factors that influence the lifespan of patients with liver cancer recurrence and metastasis after liver transplantation (t =2.843, 3.061,22.781,5.617, P <0.01). Conclusions Comprehensive treatment could prolong the lifespan of patients with liver cancer recurrence and metastasis after liver transplantation. The efficacy of comprehensive treatment is superior to that of the chemotherapy.

In recent years, people have paid more attention to the spermatogonial stem cells that have the capacity for self renewal and multilineage differentiation and produce daughter cells that can expand and differentiate into spermatozoa under the adjustment of self genes and external signal. This article reviews recent advances in studies of enrichment and original selection of the spermatogonial stem cells. This review also summarizes some control factors in proliferation and transplantation techniques.

OBJECTIVEThe aim of this study was to determine the expression of genes of the oligodendrocyte lineage-myelin basic protein (Golli-MBP) in peripheral blood mononuclear cell (PBMC) in oral lichen planus (OLP) and to further understand the pathogenesis of OLP.

METHODSPBMC was obtained by density gradient centrifugation, and the expression of Golli-MBP in PBMC was investigated in erythematous/erosive OLP (20 cases), reticular OLP (16 cases) and normal controls (19 cases) using reverse transcription-polymerase chain reaction (RT-PCR) and Western blot methods.

RESULTSRT-PCR results showed that Golli-MBP mRNA was overexpressed in erythematous/erosive and reticular OLP as compared with normal control group (P < 0.01). Western blot assay indicated that erythematous/erosive and reticular OLP patients had a higher expression level of Golli-MBP protein in PBMC than normal controls (P < 0.01). However, there were no significant differences between erythematous/erosive and reticular groups in Golli-MBP mRNA and protein expression (P > 0.05).

CONCLUSIONThe data accumulated here strongly indicate that Golli-MBP was involved in the pathogenesis of OLP.

Objective To investigate the role of hippocampal cyclophilin D (CypD) in sepsis-associated encephalopathy in rats.Methods A total of 36 adult male Sprague-Dawley rats,aged 3-4 months,weighing 300-400 g,were randomly divided into 3 groups (n =12 each) using a random number table:sham operation group (Sham group),sepsis group (S group),and sepsis + CypD inhibitor cyclosporin A group (CsA group).Sepsis was induced by cecal ligation and puncture (CLP).Cyclosporin A 6 mg/kg was injected intraperitoneally at 30 min before CLP in group CsA.All the animals underwent Morris water maze test on 4th day after CLP.The animals were sacrificed after the test,and the hippocampus was isolated for determination of the expression of cytochrome c (Cyt c),CypD,caspase-3,brain-derived neurotrophic factor (BDNF),phosphorylated protein kinase A (p-PKA),and phosphorylated cyclic adenosine monophosphate response element-binding protein (p-CREB).Results Compared with group Sham,the escape latency was significantly prolonged,the space exploration time was shortened,the expression of Cyt c,CypD,caspase-3,p-PKA and p-CREB was up-regulated,and the expression of BDNF was down-regulated in S and CsA groups (P＜0.05).Compared with group S,the escape latency was significantly shortened,the space exploration time was prolonged,the expression of Cyt c,CypD,caspase-3,p-PKA and p-CREB was down-regulated,and the expression of BDNF was up-regulated in group CsA (P＜0.05).Conclusion Hippocampal CypD may be involved in the pathophysiological mechanism of sepsis-associated encephalopathy,and the downstream mechanism is probably related to promotion of activation of PKA/CREB signaling pathway in rats.

Objective To investigate the prevalence and awareness rate of adult diabetes mellitus and the risk factors in Liaoning Anshan. Methods A cross-sectional population survey was performed among residents in Liaoning Anshan and 2 500 subjects participated. Subjects whose fasting plasma glucose ≥ 5.6 mmol/L were confirmed by oral glucose tolerance test (OGTT). Results The standardized prevalence of adult diabetes mellitus over the age of 20 in Liaoning Anshan was 8.2%, and the standardized prevalence of pre-diabetes mellitus was 14.8%. The prevalence of diabetes mellitus increased with age (P<0.05). The awareness rate of diabetes mellitus in Liaoning Anshan was 52.3%(125/239), and the awareness rate of pre-diabetes mellitus was 8.7%(35/402). Logistic regression indicated that age, family history of diabetes, overweight or obesity, waist circumference, hypertriacylglycerolemia was the risk factors (P<0.05), while regular exercise was protective factor (P<0.05). Conclusions The current prevalence of diabetes mellitus and pre-diabetes mellitus in Liaoning Anshan is higher, and the awareness rate is lower.

OBJECTIVE Tostudytheeffectofeffectivefractions(EFC)frommodifiedSimiaoWan (MSW)onthelevelofuricacidinhyperuricemicratsandinvestigatethemechanism.METHODS Two types of hyperurice mic models were established.A persistant hyperurice mic model was prepared by giving rats oxonic acid 200 mg·kg -1 and feeding the m with hypoxanthine.The models were ig given with modified Simiaowan (MSW)50 g·kg -1 or EFC 1 2.5,25 and 50 g·kg -1 consecutively for 5 d.The models were treated with MSW or EFC 50 g·kg -1 for 3 d.After the final treatment,the uric acid concen-trations in seru m and urine were determined by an auto matic bioche mistry analyzer.The activity of xan-thine oxidase (XOD )in the serum and liver was determined by enzymic colorimetric method.The activity of purine nucleoside phosphorylase (PNP)and uricase was detected by spectrophotometry. RESULTS Comparedwithnormalcontrolgroup,theserumlevelofuricacidinbothmodelgroupswas remarkably increased(P<0.01 ).Compared to model control group,MSW 50 g·kg -1 and EFC 12.5, 25 and 50 g·kg -1 significantly reduced the serum level of uric acid(P<0.05,P<0.01 ),but increased the activity of erythrocyte PNP(P<0.01 )in the oxonic acid potassium-induced hyperuricemia rats. MSW 50 g·kg -1 and EFC 50 g·kg -1 elevated the activity of liver uricase in the nicotinic acid-induced hyperuricemia rats(P<0.05).EFC 50 g·kg -1 also significantly decreased the serum XOD activity of hyperuricemicrats.CONCLUSION EFCsignificantlyinhibitstheserumlevelofuricacidinhyperurice-mic rats,which might involve down-regulation of protein levels of serum XOD to inhibit the production of uric acid and activation of uricase to pro mote the deco mposition of uric acid.
