Objective To investigate the serum procalcitonin (PCT) levels in sepsis caused by the bacteria,virus and mycoplasma and explore the role of PCT in etiology diagnosis of sepsis in children.Methods Three hundreds and thirty critically ill children with sepsis caused by bacteria,virus and mycoplasma admitted in PICU of Hunan Children' s Hospital from Feb 1,2011 to Sep 1,2012 were reviewed and analyzed.The PCT levels were measured at admission and day 3.The differences in accidence of sepsis caused by bacteria,viruses and mycoplasma according to different serum PCT levels were analyzed.The differences of PCT levels at admission and day 3 in sepsic children caused by bacteria,viruses and mycoplasma were analyzed.Results The level of serum PCT in sepsis caused by bacterial infection were distinctly increased,caused by virus and mycoplasma infections was not obvious but the increases of serum PCT [0.71 (8.14)ng/ml,0.15 (1.68) ng/ml,0.28 (1.89) ng/ml].According to various PCT levels(0.05 ～ ng/ml,0.5 ～ng/ml,2 ～ ng/ml,10 ～ 300 ng/ml),the differences of accidence of sepsis caused by bacteria,virus and mycoplasma were also statistically significant(x2 =84.50,P ＜ 0.01).The PCT level of septic children caused by bacterial infection in day 3 was significantly decreased compared with that at admission [0.32 (5.68) ng/ml vs 0.71 (8.14) ng/ml] (U =19.34,P ＜0.05).Conclusion PCT plays a certain role in etiology diagnosis of sepsis in children.The increased PCT levels which can be reduced by anti-inflammatory treatment indicate the likelihood of bacterial infection and sepsis.The increase of PCT induced by viral and mycoplasma infections is not obvious,but bacterial infection can not be completely ruled out.

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.

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 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.
