Objective To study the effect of hype rt hermia on cytokines of VX_2 carcinoma bearing rabbits. Method Forty healthy male rabbits were randoml y divided into heat therapy group and control group. Rabbits in heat therapy gro up underwent hyperthermia 11 days after inoculated with VX_2 cells. IL-2, tumor necrosis factor (TNF) and insulinlike growth factor (IGF) were measured b efore and after heat therapy. Results In heat therapy group survival was prolonged for 15 days. IL-2 d ecreased gradually from (134?6)ng/ml before heat therapy, (81?7)ng/ml one week after, (61.8?2.0)ng/ml at 3 weeks, and (54.8?2.6)ng/ml at 4 weeks along with an increase of TNF and IGF (4.5?0.9)ng/ml, and ( 96?28)ng/ml; (7.6?1.8)ng/ml and (678?183)ng/ml; (15.1?3 .0)ng/ml and (991?108)ng/ml; (17.2?2.1)ng/ml and (1136?89 )ng/ml respectively at the corresponding time period. Conclusion Heat therapy is effective for the tre atment of superficial tumors probably through a mechanism of antigen-antibody r eaction.

Objective To investigate the relationship between chronic prostatitis and the coagulase-negative staphylococci (CNS),and to study the diagnostic value and clinical significance of CNS in expressed prostatic secretion (EPS). Methods Overall,428 patients with chronic prostatitis were included in this study.Their mean age was 31 years (range,18 to 46 years).The mean cause was 6 months (range,3 to 32 months).The mean NIH-CPSI score was 23.2.Bacterial culture and antimicrobial agent sensitivity test were applied to samples from the 428 patients.The samples were taken with 4 tubes from the lower urinary tract segmented by Meares-Stamey method. Results Bacteria were found in 248 patients (57.94%) out of 428 ones.Gram-positive bacteria were found in 195 cases(78.63%).In the 195 cases,staphylococci were found in 160 cases(64.25%,160/248).CNS were found in 89 cases(35.89%,89/248),most of which were epidermidis staphylococci 81 cases(32.66%).The next were saprophytic staphylococci 3 cases and hemolytic staphylococci 2 cases.There was no correlation between NIH-CPSI score and bacterial culture results.The sensitivity test results showed the rate of drug resistance of CNS from EPS was high for ?-lactamases,quinolones and aminoglycosides(51.9% to 100%). Conclusions The results suggest that CNS is a main kind of pathogen of chronic prostatitis,so considerable attention should be paid to it.In addition,it is of significant importance to apply bacterial culture and sensitivity test in EPS to the diagnosis and treatment of chronic prostatitis.

Objective:To investigate esomeprazole combined with early enteral nutrition on the immune function and intestinal flo-ra in the elderly by patients with severe acute pancreatitis. Methods:Totally 78 elderly by patients with severe acute pancreatitis were selected and randomly divided into the observation group (39 cases) and the control group (39 cases). The control group was treated with early enteral nutrition therapy, and the observation group was treated with esomeprazole additionally. The treatment course was 14 days. Results:The total effective rate of the observation group was higher that of the control group (P<0. 05). The abdominal pain relief time, recovery time of bowel sounds, abdominal distension relief time, and the time of serum amylase returning to normal and u-rine amylase returning to normal in the observation group were all better than those in the control group (P<0. 05). The incidence of intestinal flora disorders in the observation group was lower than that in the control group (P<0. 05). After the treatment, CD3+, CD4+ and CD4+/CD8+ increased in both groups (P<0. 05), and those in the observation group were higher than those in the con-trol group (P<0. 05). Serum amylase and urine amylase decreased in both groups after the treatment (P<0. 05), and the decrease in the observation group was more significant than that in the control group (P<0. 05). No serious adverse drug reactions appeared in both groups. Conclusion:Esomeprazole combined with early enteral nutrition in the elderly by patients with severe acute pancreatitis shows significant effect, and the effect may be related with improving the immune function and intestinal flora.

Objective To evaluate early diagnosis and preemptive therapy of human cytomegalovirus infection in renal transplant recipients. Methods We selected 165 renal transplant recipients who underwent transplantation from January 2007 to January 2009 and adhered to follow-up as research subjects. The samples of blood and urine were collected before transplantation, every 1 week from 2 to 8 weeks and every 2 weeks from 9 to 24 weeks after transplantation. The viral load of blood and urine was detected by fluorescence quantitative polymerase chain reaction (FQ-PCR). Once HCMV DNA load was more than 103 copies/ml, preemptive therapy was done immediately by ganciclovir. Results All the samples of blood and urine were negative before operation. HCMV DNA load could be detected in the concentrated urine at the second week and the peak of HCMV DNA loadoccurred from the sixth to eighth week after operation. At the same detection time, the number ofpositive recipients in the concentrated urine was more than in blood. In 30 cases HCMV DNA load was detected in the blood and the positive rate was 18.18%. In 64 cases HCMV DNA load was detected in the concentrated urine and the positive rate was 38.79%. The positive rate of the concentrated urine was significantly higher than in blood (P＜0.05). In 30 cases positive for HCMV DNA in the blood and urine, ganciclovir was given and the viral load was decreased gradually. But 8 recipients developed into CMV pneumonia and were cured through the comprehensive treatment. The clearance time of HCMV DNA in the concentrated urine was 10.2 ± 3.4 days. Thirty-four cases that were only positive for HCMV DNA in the urine were also treated by ganciclovir and no case developed into CMV pneumonia. The clearance time of HCMV DNA was 5.5 ± 2.1 days, and the clearance time was shortened as compared with that in those positive for HCMV DNA in the blood and urine (P＜0.05). Conclusion FQ-PCR can detect HCMV DNA in the concentrated urine in advance and increase the positive rate. Once the sample of the concentrated urine is positive, preemptive therapy has a good effect.

Objective To evaluate the bonding condition of hydroxyapatite (HA)/zirconia ( ZrO2 ) composite and bone interface and the ability of HA/ZrO2 in repair of bone defects.Methods Bone defect models were established in the lumbar vertebral body of 24 Beagle dogs and were implanted with HA/ZrO2 gradient composite (Group A ),HA/ZrO2 unilayer composite (Group B ),pure ZrO2 (Group C) and pure HA (Group D) successively.Dogs were sacrificed and lumbar vertebral specimens were harvested 6,12,16 weeks postoperatively and before the sacrifice at postoperative 6 and 12 weeks,the dogs were intramuscularly administered of quadracycline for fluorescence labeling.The interface bonding and repair of bone defects were observed through X-ray films,histomorphology and biomechanical test.Results The X-ray films displayed that the Group A achieved more formation of osteotylus and better repair of bone defects with the extension of the implantation period,followed by the Groups B and D and that the Group C had relatively worse results.Histomorphology study showed that the fluorescence labeling was enhanced gradually from 6 to 12 weeks in the Group A,with its growth from the edge of the implanted material to the inner part and its tight adhesion to the material,indicating active osteogenesis and massive bone formation.While the fluorescence labeling of the Groups B,C and D centered in the edge of implanted materials without presence in the material inner part.The mineralization rate of the four materials at 6 and 12 weeks had significant differences ( P ＜ 0.05).Synostosis rates at 6,12 and 16 weeks were the highest in the Group A,with the rate of up to (90.26 ±3.82) ％ at 16 weeks (P ＜0.05 ).Biomechanical test showed the maximum shear strengths at 6,12,16 weeks in the Group A were (2.64±0.16) MPa,(2.95 ±0.19) MPa and (3.45 ±0.23) MPa respectively (P＜0.05).Conclusion HA/ZrO2gradient biocomposite bonds well with the bone and possesses good repair ability for bone defects and hence is an ideal novel material for bone defect reconstruction.

BACKGROUND:Bone cement containing antibiotics for repair of bone defects can achieve sustained release of a higher concentration of sensitive drugs, which wil help kil bacteria and provide the necessary bone grafting bed and space to reduce massive bleeding due to removal of the granulation at bone defects during the second phase. OBJECTIVE:To analyze the clinical efficacy of antibiotic bone cement combined with autologous bone transplantation and Ilizarov external fixator on tibial bone defects after traumatic osteomyelitis. METHODS:A total of 31 patients with tibial bone defects after chronic osteomyelitis, including 19 males and 12 females, aged 17-40 years old. After positive debridement of necrotic tissues at bone stump, Ilizarov external fixator was used for fracture fixation, and autogenous iliac bone grafting combined with bone cement containing antibiotics was performed to repair bone defects. Fracture healing time, knee and ankle scoring were fol owed up. RESULTS AND CONCLUSION:The 31 patients were fol owed up for 6 months to 3.5 years. Tibial fractures were healed without infection recurrence in al patients. The bony union time was 3-6 months, the fixation time was 3-6 months, and the limb extended length was (7.50±1.01) cm. No adverse reactions related to bone cement and bone graft occurred. At 3 months after bone grafting, the scores on the knee and ankle joints were improve significantly. These findings indicate that the antibiotic bone cement combined with autologous bone transplantation and Ilizarov external fixator for repair of post-osteomyelitis posterior tibial bone defects can control infection, promote fracture healing, and restore joint functions.
