Objective: To estimate the clinical efficacy of combination of chemotherapy with osteoblast promoting and anti-osteolys-is agents in bone metastatic carcinoma. Methods: Seventy-one patients with bone metastatic carcinoma were divided into 2groups and treated with protocol A or B, respectively. The protocol A was a combination of chemotherapy with osteoblastpromoting and anti-osteolysis agents, the protocol B was a combination of chemotherapy with antiosteolysis agent only. Theefficacies of the 2 protocols were compared and studied. Results:The effect of A was more remarkable than that of B in re-lieving bone pain and enhancing bone repair. No severe adverse effect of these agents was found in therapy. Conclusion: Theclinical efficacy of combination of chemotherapy with osteoblast promoting and anti-osteolysis agents in bone metastatic car-cinoma was definite, the osteoblast promoting agent as an effective adjtmctive agent can be used not only in osteoprosis butalso in bone metastatic carcinoma.

Purpose [WT5”BZ]To estabalish a quantifying model of retinal neovascularization suitable for the study of pathogenesis and therapeutic intervention for the retinal neovascularization. [WT5”HZ]Methods [WT5”BZ]Sixteen one week old C 57 BL/6 mice were exposed to 75% oxygen for 5 days and then to room air and 16 mice of the same age kept in room air as controls.Ink perfused retinal flatmount was examined to assess the oxygen induced changes of retinal vessels.The proliferated neovascular response was quantitated by counting the nuclei of endothelial cells of new vessels extending from the retina into the vitreous in 6 ?m sagittal cross sections. VEGF and bFGF were determined on the cross sections after immunohistochemcal stain. [WT5”HZ]Results [WT5”BZ]Constriction and closure of the blood vessels were found under the hyperoxia condition,and dilation and proliferation were found under the relatively hypoxia status.There was a mean of 24 neovascular nuclei per cross section in the oxygen treated retina and less than 1 nucleus in the control group ([WT5”BX]P

Objective Agaro-oligosaccharides have been proved to possess the antioxidative ability in vitro. This work focus on the preparation of agaro-oligosaccharides and their antioxidant effect in vivo. Method Agaro-oligosaccharides were hydrolytically obtained and the activated carbon column was used to purify the oligosaccharides. The antioxidative effects of the 10 % ethanol eluted fraction on tissue peroxidative damage induced by carbon tetrachloride (CCl 4) was also investigated in rat. Result Agarobiose of high purity was consequently eluted from chromatography in the fractions of 5 % and 8 % ethanol, agarotetraose and agarohexaose in 10 % to 15 % ethanol, as well as high degree of polymerization (DP) oligosaccharides in 25 % ethanol. The antioxidative results indicated that agaro-oligosaccharides could elevate the activities of SOD, GSH-Px and decrease the level of MDA, GPT, GOT significantly. At a dose of 400 mg?kg~ -1, MDA level was reduced 44 % and 21 % in liver and heart, the activities of SOD and GSH-Px would amount to the peak value in liver and serum, while GPT level was decreased 22 % in serum. Conclusion The purity of agaro-oligosaccharides with different range of DPs was improved by activated carbon column, which possesses the property of different absorbance ability towards oligosaccharides with various DPs and high isolating capability. The animal test also indicated that agaro-oligosaccharides could inhibit the oxidative damage in vivo.

OBJECTIVE:To observe clinical efficacy and ADR of Houttuynia cordata eye drops combined with Olopatadine eye drops in the treatment of allergic conjunctivitis. METHODS:160 eyes with allergic conjunctivitis were randomly divided into observation group and control group,with 80 eyes in each group. The control group was given olopatadine eye drops,and observa-tion group was additionally given H. cordata eye drops(medication interval>10 min)on the basis of control group. Both groups were treated for 14 days. Symptoms and signs of 2 groups were observed and scored before treatment and 14 d after treatment. Ef-fective rates of 2 groups were calculated,and the occurrance of ADR was observed. RESULTS:Compared with before treatment, symptoms and sings score of 2 groups were decreased,with statistical significance (P<0.01 or P<0.05);the decrease of two score in observation group were more significant than in control group,with statistical significance (P<0.05);effective rates of control group and observation group were 37.50%and 77.50%,with statistical significance(P<0.05). CONCLUSIONS:H. corda-ta eye drops combined with olopatadine eye drops can ameliorate clinical symptoms and signs of allergic conjunctivitis patients sig-nificantly,and improve therapeutic efficacies without obvious ADR.

Chronic obstructive pulmonary disease (COPD) is a chronic airway diseases,which leads to heavy social and economic burden to our country.We can use serum biomarkers to evaluate diagnosis,classification,treatment and prognosis of COPD.The change of biomarkers provides lots of valuable clinical information.A variety of biomarkers are associated with the severity of lung function,which can be used to judge disease severity.Some indicators are related to the diagnosis of acute exacerbation or hospitalization risk.Some serum markers would guide therapy and can be effectively applied to clinical work.Study of COPD serum biomarkers would provide more reference information for clinical physicians in diagnosis,treatment and prognosis of COPD.

OBJECTIVE: To study the effect of continuous renal replacement therapy on acute renal failure and multiple organ dysfunction syndrome following simultaneous pancreas-kidney transplantation. METHODS: A patient was complicated with acute renal failure, severe acute pancreatitis, lung infection, bleeding in anastomosisbetween duodenum and jejunum, and peritonitis following simultaneous pancreas-kidney transplantation. He was treated with immunosuppressor, antibiotics, amylopsin inhibitor, haemostatic and alimentation; at the same time, he was treated with continuous renal replacement therapy for 22 days. The Baxter system was used for continuous venovenous hemofiltration. RESULTS: The vital signs and hemodynamic indicators were stable during continuous renal replacement therapy. Pulmonary edema was well controlled, and acid-base equilibrium of water electrolyte was maintained. The function of vital organs was stableand graft function was normal following continuous renal replacement therapy for 22 days. He was completely cured and out of hospital on day 40. CONCLUSION: Continuous renal replacement therapy plays an important role in treating acute renal failure and multiple organ dysfunction syndrome following simultaneous pancreas-kidney transplantation. Thus, it is a well kidney support for ultaneous pancreas-kidney transplantation.

Objective To discuss the clinical application and value of dual-source spiral CT enhanced scan and multiplanar reformatting ( MPR) in the diagnosis of gastric cancer. Methods The 335 patients with gastric cancer who conducted dual-source spiral CT enhanced scan of upper abdomen under the hypotonic state before the definite pathological diagnosis were retrospectively analyzed,and had multi-di-mensional multiplanar reconstruction for the enhanced thin-section CT data by the multiplanar reformatting technique. Results Of 335 ca-ses,288 cases were detected by simple axial data,the detection rate was 86. 0%,320 cases were detected by MPR,the detection rate was 95. 5%,the differences were statistically significant (P<0. 05). The overall accuracy rate of Preoperative T staging by conventional axial and MPR images were 78. 3% and 89. 1% respectively, the difference was statistically significant. The overall accuracy rate of preoperative N staging by two methods were 73. 6% and 82. 3%,respectively,the difference was not significant. Conclusion Application of dual source spiral CT multiplanar reconstruction can significantly improve the detection rate of gastric cancer,and the average accuracy rate of preopera-tive TNM staging for gastric cancer is 84. 6%.
