Objective:To investigate a potential role of Toll-like receptor 4(TLR4) ,a pathogen pattern recognition receptor, in the early phase of severely burned rats. Methods: Rats burn model(30% of total body surface area[TBSA],Ⅲgrade) were established with vapor at 108 C for 8 seconds. Rats were sacrificed before and 2,5,12,24,48 and 72 h after burning, and the spleen specimens and peripheral blood samples were harvested. TLR4 mRNA and TNF-?mRNA expression in splenocyte was measured by reverse-transcription PCR(RT-PCR); the expression of TLR4 protein were measured by Western bloting; the endothelial toxicity concentration in plasma was detected by limulus lysate test. Results: It was found that the expression of TLR4 mRNA.TNF-?mRNA,TLR4 protein,and the level of ET were significantly increased in burned group compared with normal control group. The expression of TLR4 mRNA and protein peaked at 8 h after burning, the expession of TNF-?mRNA peaked at 12 h.and the level of ET peaked at 8 h after burnings the peak values of them were (3. 66?0. 51),(2. 27?0. 19), (1.65?0. 23),and (11. 68?2. 63) Eu/ml, respectively, all significantly higher than those of the control group(P

Objective To isolate and purify the antibacterial peptides from larvae secretion of housefly (Musca domestica) and study their partial characteristics. Methods Protein isolation and purification were performed by routine process, namely, ultrafiltration, solid phase extraction (SPE) and reversed-phase high-performance liquid chroma-tography (RP-HPLC). The minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of the antibacterial peptides were examined. The antibacterial effect of peptides was studied in nutritive medium with different pH value(pH 5.0-10.0), divalent cations (Mg2+: (0.5?10-3～10.0?10-3)mol/L, Na+、K+: (10?10-3～100?10-3)mol/L), and serum content(12.5%～75%). Results Molecular weight of the peptides was about Mr 3 000-30 000 after ultrafiltration. The fractions eluted with 20%, 30%, 70%, and 80% of acetonitrile (ACN) all showed antibacterial activity by solid phase extraction. The fractions eluted with 70% ACN showed strongest and stablest antibacterial activity which was further purified by RP-HPLC. Two sub-fractions appeared at around RT 15.5 min and 18.5 min were obtained with antibacterial activity. The MIC to those standard Escherichia coli, Pseudomonas aerugirwsa, Staphylococcus aureas, and Bacillus subtilis was 32.7380, 16.3688, 65.4750 and 32.7380?g/ml respectively. In the nutritive medium of pH 6.0-9.0, different divalent cations and serum content, the increment of A570 in experiment groups was less than 0.05, while that of the control group was greater than 0.3 (P

OBJECTIVETo observe the curative effect of massage in the treatment of primary dysmenorrhea (PD), and its effect on hemodynamics parameters of uterine artery and serum prostaglandins.

METHODS60 PD patients were randomly assigned to the massage group and the control group, 30 in each. Patients in the massage group received massage, while those in the control group orally took ibuprofen sustained release capsule, both for three menstrual cycles. The pain degree was assessed using visual analogue scale (VAS). The hemodynamics parameters of uterine artery [including pulsatility index (PI), resistance index (RI), systolic to diastolic peak ratio (S/D)], the serum levels of prostaglandin F2alpha (PGF2alpha) and PGE2 in the menstruation were detected in the two groups before and after treatment.

RESULTSThere was no statistical difference in each index before treatment between the two groups (P>0.05). Compared with the control group after treatment, the scores of VAS (mm, 33. 17+/-7.93 vs 63.53+/-9.48), PI (2.18+/-0.18 vs 2.74+/-0.23), RI (0.67+/-0.09 vs 0. 86+/-0.27), S/D (5.44+/-0.47 vs 7.56+/-0.28), and serum PGF2a level (ng/L, 28. 10+/-2.41 vs 37.68+/-2.16) were lower and serum PGE, level (ng/L, 29.82+/-2.13 vs 26.43+/-1.42) higher in the massage group, showing statistical difference (P<0.05, P<0.01).

CONCLUSIONSMassage had favorable therapeutic effect on PD. Its effect might be achieved through improving the blood circulation of uterus, adjusting the abnormal levels of PGF2a and PGE2, thus exerting pain relief effect.

Objective To evaluate the clinical value of 18floro-deoxyglucose positron emission tomography-CY(~(18)FDG PET-CT)in the diagnosis of lymph node metastasis from advanced esophageal carcinoma. Methods A prospective study is perfonued here to assess whether ~(18)FDG PET-CT can improve the diagnostic accuracy in lymph node metastasis for patients with advanced esophageal carcinoma.Thirty patients had undergone esophagectomy with extensive lymph node dissection.PET-CT findings were compared with that d CT with pathological finding as the final say.Results All patients were operated successfully without peri-operative complications.The pathological examination conformed metastasis in 22 patients and 49 out of 243 excised lymph nodes.In CT analysis,the sensitivity was 40.8%,specificity was 96.9%,with a diagnostic accuracy of 85.6%, The positive and negative predictive value was 76.9%,86.4% respectively;PET-CT resulted in a sensitivity of 93.9%,specificity of 91.2%,accuracy of 91.8%.The positive predictive value was 73.0% and negative predictive value was 98.3%,The difference of sensitivity(P＜0.001),accuracy(P＜0.05)and negative predictive value between the two radiological modalities was statistically significant(P＜0.001).Conclusions With a high sensitivity and accuracy in the diagnosis of lymph node metastasis,PET-CT appears necessary in preoperative examination for advanced esophageal carcinoma in the hope that surgical treatment be guided by the results of PET-CT,especially for the elder patients with poor pulmonary function or heart or brain complications. Moreover,it could be used as the basis of the conformal radiation therapy planning for inoperable patients.

Objective To evaluate the clinical value of 18-fluoro-deoxyglucose positron emission tomography-CT(~(18)FDG PET-CT) for recurrence and metastasis in treated esophageal carcinoma (EC). Methods A retrospective study is done on 37 previously treated EC patients who underwent PET-CT scans to detect recurrent or metastatic lesions.The diagnostic accuracy of ~(18)FDG PET-CT was assessed with the help of pathological finding as well as clinical or follow-up data.Results Fourty-six sites of recurrence were finally confirmed in 37 patients by cytology,pathology or follow-up data.The sensitivity,specificity and accuracy of PET-CT in detecting recurrence of all sites were 93.5% (43/46),76.9% (20/26) and 87.5% (63/72),respectively.Two false-positive findings were found both at the anastomosis and hilar nodes,which caused the decrease in the overall specificity,especially that locally.The analysis of standard uptake value (SUV) demonstrated that patients with recurrence or who died during follow-up had higher SU- Vs compared with the control group.Condusions ~(18)FDG PET-CT is highly effective in detecting recur- rence in previously treated EC patients despite the low specificity at local sites.The analysis of stardard up- take value(SUV) provides incremental value in prognosis for this patient cohart.
