Clinical Observation on Efficacy of Ulinastatin in Treatment of Sepsis Induced Acute Renal Injury / 现代生物医学进展

Objective:To research the clinical effects of ulinastatin in the treatment of sepsis induced acute renal injury and its possible mechanisms.Methods:114 cases of patients with sepsis induced acute kidney injury from 2014.02 ～ 2016.08 were selected and randomly divided into the control group (n=57) and experimental group (n=57) according to the draw method,the control group was given conventional treatment,while the experimental group was treated by ulinastatin based on the control group,the urine urinary injury molecule-1 (KIM-1),atrialnatriuretic peptide (ANP),cyscatin-c (CYS-C),interleukin l,6 (IL-1,IL-6),c-reactive protein (CRP),tumor necrosis factor-α(TNF-α),nitric oxide (NO),endothelin 1 (ET-1),immunoglobulin A,G,M (IgA,IgG,IgM) levels,APACHE-Ⅱ score were compared between two groups before and after the treatment.Results:After treatmented,the urine of KIM-1,ANP,serum of CYS-C,IL-l,IL-6,CRP,TNF-α,ET-1 levels and APACHE-Ⅱ score of experimental group were significantly lower than those of the control group (P＜0.05).The serum NO,IgA,IgG,IgM levels of experimental group were significantly higher than those of the control group (P＜0.05).Conclusion:Ulinastatin could significantly relieve sepsis induced acute renal injury,which might be related to the inhibition of inflammatory response,improvement of the renal blood flow and immune function.

Effect of Geraniin on Expression of Wnt3a in BMSC from Osteoporotic Rats / 昆明医科大学学报

Objective To investigate the effect of geraniin on expression of Wnt3a protein and mRNA in bone marrow stromal cell (BMSC) from osteoporotic rats. Methods The model of osteoporosis (OP) was duplicated by ovariectomy in rats. BMSCs were isolated and cultured. BMSCs from shamed rats were routinly cultured and taken as normal control, and BMSCs from OP rats were divided into model group, 1μmol/L simvastatin positive group, and geraniin group (0.01, 0.1, 1, 10, 100 μmol/L), respectively. The methods of realtime-PCR and western blot were used to assay the protein and mRNA expression of wnt3a, respectively.Results As compared with normal control group, the protein and mRNA expression of wnt3a in model group were significantly suppressed;Compared with model group, 1 μmol/L simvastatin, and 0.1, 1, 10 and 100 μmol/L geraniin significantly increased the expression of wnt3a protein and mRNA. Conclusion It is suggested that geraniin activates wnt/β-catenin pathway though increasing the expression of signaling protein wnt 3a in BMSCs from OP rats. It would be beneficial to osteogenic differentiation of BMSCs and osteogenesis.

A multicenter randomized phase II trial of domestic product of nrhTNF in the treatment of non-small cell lung cancer / 中国肺癌杂志

<p><b>BACKGROUND</b>To evaluate and compare the effects and toxicity of the domestic product of nrhTNF combined with chemotherapy in the trial group and chemotherapy alone in the control group in the treatment of patients with non-small cell lung cancer (NSCLC).</p><p><b>METHODS</b>Ninety patients with NSCLC in multicenter were randomly devided into trial group and control group. Each group had 45 patients. Chemotherapy with CAP regimen was given for the patients in the trial group. Meanwhile, nrhTNF injection of 4×10⁶U/m ² was also given from the 1st to 7th days, the 11th to 17th days on the chemotherapy course. Twenty-one days were as a cycle, 2 cycles were given each patients. Chemotherapy alone with CAP regimen was given in the control group. The chemothepeutic effects and toxicity were observed and compared between the two groups after the therapy.</p><p><b>RESULTS</b>Of the 90 patients, 3 cases in each group were out of the trial because of economy. The other 84 cases (each group had 42 patients) could be used to analyze and evaluate the clinical effects and toxicity. The response rate of chemotherapy was 47.62% (20/42) in the trial group and 19.05% (8/42) in the control group (P=0.002) respectively. The KPS was 85.02±10.74 in the trial group, and 81.35±9.63 in the control group (P=0.038). No significant difference of degree III+IV toxicity was observed between the trial group and control group (P > 0.05). The side effects related to nrhTNF included slight fever, cold like symptoms, pain, and red and swelling in injection site. All of them were mild and didn't need any treatment and disappeared after the therapy.</p><p><b>CONCLUSIONS</b>The results demonstrate that the effects of domestic nrhTNF combined with chemotherapy can remarkably higher than that of chemotherapy alone in the treatment of NSCLC. It is able to increase the sensitivity to chemotherapy and improve the quality of life of the patients. The toxicity is also slight and is worth to expand clinical use, so as to further evaluate its effect and toxicity.</p>

A multicenter randomized phase III trial of domestic product of rmhTNF in the treatment of non-small cell lung cancer / 中国肺癌杂志

<p><b>BACKGROUND</b>To evaluate and compare the effects and toxicity of the domestic product of recombinant mutant human tumor necrosis factor (rmhTNF) combined with chemotherapy and chemotherapy alone in the treatment of patients with non-small cell lung cancer (NSCLC).</p><p><b>METHODS</b>Two hundred patients with NSCLC in multicenter were randomly devided into trial group (150 cases) and control group (50 cases). Chemotherapy with CAP regimen was given to the patients. Meanwhile, rmhTNF injection of 4×10⁶U/m² was also given from the 1st to 7th days, the 11th to 17th days on the chemotherapy cycle in the trial group. The control patients received chemotherapy alone. Twenty-one days were as a cycle, 2 cycles were given to each patient. The chemotherapeutic effects and toxicity were observed and compared between the two groups after the therapy.</p><p><b>RESULTS</b>of the 200 patients, 5 cases in the trial group and 3 cases in the control group were out of the trial because of economy. The other 192 cases (145 cases in the trial group and 47 cases in the control group) could be analyzed and evaluated the clinical effects and toxicity. The response rate of chemotherapy was 46.90% (68/145) in the trial group and 17.02% (8/47) in the control group respectively ( P =0.001). The KPS scores was 86.02±9.74 in the trial group, and 80.14±9.10 in the control group ( P =0.025). No significant difference of degree III+IV toxicity was observed between the two groups ( P > 0.05). The side effects related to rmhTNF included slight fever, cold-like symptoms, pain and red and swelling in the injection site. All of them were mild and didn't need any treatment and disappeared after the therapy. There were no severe abnormality of liver and kidney function and ECG in both groups.</p><p><b>CONCLUSIONS</b>The results demonstrate that the effects of domestic rmhTNF combined with chemotherapy are remarkably higher than that of chemotherapy alone in the treatment of NSCLC. rmhTNF can increase the sensitivity to chemotherapy and improve the quality of life of the patients with slight toxicity. Hence rmhTNF is worth expanding clinical use.</p>

<p><b>BACKGROUND</b>To study the immuno-function of erythrocytes and the influence of surgical treatment on it in the patients with lung cancer.</p><p><b>METHODS</b>A total of 61 patients with lung cancer were studied, consisting of 35 non-operative patients and 26 post-operative patients. Their immuno-function of erythrocytes was analyzed and compared with 30 normal controls.</p><p><b>RESULTS</b>In the post-operative group, the values of RBC C3BRRT and NTER were significantly higher than those of non-operative group (P < 0.01), but still lower than those of normal control group (P < 0.05); RFER, DTER, ETER and ATER higher than those of non-operative group (P < 0.01), and not significantly different from normal control group (P > 0.05); RBC ICR lower than that of non-operative group (P < 0.01), and not remarkably different from normal control group (P > 0.05); and RFIR lower than that of non-operative group (P < 0.01), however, still higher than that of normal control group (P < 0.01).</p><p><b>CONCLUSIONS</b>The immuno-function of erythrocytes may be related to body tumor load of the patients with lung cancer, and it may gradually recover after the primary tumor is resected.</p>

MR Appearances of Anterior Cruciate Ligament Injury of Knee Joint / 实用放射学杂志

Objective To evaluate MR appearances of normal and injured anterior cruciate ligament(ACL).Methods The MR findings of normal ACL in 16 cases and ACL tear in 15 cases were reviewed retrospectively.Results Normal ACL appeared as a flat band with low signal intensity on T1 and T2-weighted imaging. The injured ACL can appeared as interruption in continuation(n=5), irregular shape(n=1),abnormal direction(n=2) and increased in signal intensity(n=7).Conclusion MRI is a accurate and noninvasive diagnostic method for ACL tear.
