Objective To explore the clinical value of serum procalcitonin(PCT)and C-reactive protein(CRP)combination detec-tion in early diagnosis of liver cirrhosis complicating spontaneous bacterial peritonitis(SBP).Methods The peripheral blood sam-ples were collected from 30 cases of liver cirrhosis complicating SBP,30 cases of simple ascites liver cirrhosis (non-SBP)and 45 healthy subjects as control group.The serum PCT level was detected by the dry immunofluorescence quantitation method and the serum CRP level was detected by the immunoturbidimetry.The sensitivity and specificity of PCT,CRP and PCT combined with CRP in diagnosing liver cirrhosis complicating SBP were compared and the relationship between PCT levels and prognosis was ana-lyzed.Results Compare with the healthy control group and the non-SBP group,the serum PCT and CRP levels in the SBP group were markedly increased(P <0.05).The sensitivity of PCT,CRP and PCT combined with CRP in diagnosing liver cirrhosis compli-cating SBP was 93.3%,90.0% and 96.6% respectively,and the specificity was 90.0%,75.0% and 95.0% respectively.Conclusion The combination detection of serum PCT and CRP can increase the sensitivity and specificity of the diagnosis and has more clini-cal value in early diagnosing liver cirrhosis complicating SBP.

Objective To evaluate the effects of preoperative regional artery chemotherapy (PRACT) on gastric carcinoma. Methods Celiac arteriography was performed by transfemoral artery catheter according to Seldinger's method and superselective catheterization proceeded to the supplying artery of focus of lesion. Antineoplastic agents of Fluorodeoxyuridine (FUDR)(0.8 g/m 2), epirubicin(40 mg/m 2), oxaliplatin(80 mg/m 2) were infused into regional artery by a single administration. The specimens from 14 cases of gastric carcinoma(GC) who received PRACT were separated into pre operation group and post operation group. Both microscopic study to observe the necrosis of cancer cell and TUNEL(TdT mediated dUTP nick end labeling) method to detect the state of apoptosis were performed respectively in the two groups. Correlation of apoptosis index (AI) between the two groups, as well as correlation between the situation of necrotic tumor cell and the blood vessel, was analyzed. Results The severity of the necrosis of tumor cell was significantly higher in the PRACT group than that in the untreated group ( P

To investigate the immunological activities of the recombinant human phosphatase D2 (rhPLD2) in vitro and in vivo, especially its ability to reduce inflammatory reactions, the cDNA fragment encoding rhPLD2 was cloned into prokaryotic expression vector pET30a by RT-PCR and the recombinant protein rhPLD2 expressed in E.coli was purified from the inclusion bodies, while the anti inflammatory activity of rhPLD2 was determined by the amount of eosinophils in bronchoalveolar fluid(BALF) and blood and the expression of IL-5 and MMP-9 in lung tissues of guinea pig model of chronic asthma. It was found that the rhPLD2 recombinant protein was obtained from human Daudi cells by cloning to E.coli, which contained no membrane-binding site and signal peptide. The cDNA sequence encoded 631 amino acid residues (GenBank Accession Number: AY178289). The purity of the rhPLD2 approached up to 76% with a bioactivity of 50.9745 units/L (0.9212 g/L). In addition, the anti inflammatory effect of rhPLD2 protein could be demonstrated in the guinea pig model of chronic asthma after treatment with rhPLD2 protein, such as down regulation in the expression of the inflammatory cytokine IL-5. It is concluded that the anti-inflammator activity of the recombinant human truncated PLD2 protein produced from the E.coli plasmid can be demonstrated both in vitro and in vivo.

ObjectiveTo improve the teaching quality of medical humanity education in medical university.MethodsA cluster sampling survey was given to 448 sophomores who studied the outline of medical humanities course in military medical university,and the data were descriptively and statistically analyzed.ResultsThe survey shows that 90％ sophomores satisfy with this course,95％ sophomores understand the importance of medical humanity education,and the students have more requirements on education resources and teaching ways.ConclusionOutline of medical humanities course is important to cultivate the medical humanity spirit of medical students,and the course still needs more improvements.

Objective In this study,we aimed at investigating the clinical,laboratory and management characteristics of adolescent-onset SLE patients compared with adult-onset SLE patients.Methods 470 fe- male patients with SLE were divided into two subgroups:adolescent-onset SLE patients and adult-onset SLE patients.The analyzed variables included clinical,laboratory parameters,damage index and outcome charac- teristics.Results In 470 female patients with SLE,there were 98(20.85%)adolescent-onset SLE patients. The following manifestations occurred more frequently in adolescent-onset SLE patients:malar rash,cutaneous vasculitis,proteinuria and abnormal liver function.Adolescent-onset SLE patients had more severe disease features and had significantly higher mean value of SLEDAI.Mortality was higher in adolescent-onset SLE pa- tients than aduh-onset SLE patients.Renal and blood system were the organs that most frequently involved. Conclusion Adolescent-onset SLE patients accounts for roughly 20.85% of all SLE cases.It is necessary to pay more attention to adolescent-onset SLE patients because the management for them is usually more difficult and the prognosis is usually poorer than aduh-onset SLE patients.

Objective To histomorphometricly assess changes occurred in the alveolar ridge following different methods of socket preservation and to compare them against natural healing without interventions. Methods The second、 third and fourth mandibular premolars were extracted from six beagles. Six extraction sites in each dog were randomly assigned to three treatments as follows:natural healing (T1), Bio-Oss Collagen (T2) and immediate implant with Bio-Oss (T3). Six month after surgery, the dogs were euthanized and tissue samples were sectioned, fixed and mounted, then were stained with toluidine blue. The histologic studies and morphological measurements were performed by using an optical microscope and a digital image software. Results Reabsorption in the buccal aspect of the alveolar crest of ridge was showed in all groups. With respect to the mean vertical bone loss of the buccal bone plate, T3 is lower than T1 and T2(P<0.001 ), while no significant differences were observed between T1 and T2. With regard to horizontal dimension of the alveolar process , a statistical significance could be found at 3mm and 4mm below the crest of ridge in group T1 and T3(P=0.017, P=0.042), while no statistical differences were found between other groups. Conclusions Both techniques of alveolar ridge preservation were not able to completely preserve the original bone volume after tooth extraction. Immediate implant placement in combination with Bio-Oss seems to have the potential to limit the reabsorption of the alveolar process efficiently , but the bone preserving effect of Bio-Oss Collagen is undesirable.

Objective To investigate the clinical efficacy of Hiru doid,Sufu and Musk Hemorrhoids Ointment on preventing peripheral chemothera?peutic phlebitis due to continuous infusion of 5?fluorouracil. Methods Totally 90 patients with esophageal squamous cell carcinoma treated with continuous infusion of 5?fluorouracil were recruited and randomly divided into Hirudoid group,Sufu group and Musk Hemorrhoids Ointment group, with 30 cases in each group. Three groups were applied with drugs respectively along the vein punctured while connecting the pump of 5?fluorouracil 3 times a day(each time interval of 6 hours)for 5 consecutive days. The occurrence of chemotherapy phlebitis was observed and recorded. Results Musk Hemorrhoids Ointment and Sufu were more effective than Hirudoid in reducing the incidence of phlebitis and relieving the degree of venous in?jury(P<0.05);however,there were no differences between Musk Hemorrhoids Ointment and Sufu(P>0.05). Musk Hemorrhoids Ointment was the most effective among the three in relieving the pain caused by phlebitis(P<0.05). There were no difference between Sufu and Hirudoid(P>0.05). Conclusion Musk Hemorrhoids Ointment can effectively prevent peripheral chemotherapeutic phlebitis caused by continuous infusion of 5?fluorouracil with affordable expense which is worthy of promotion in clinic use.
