Objective To investigate the effect of nutrition support therapy on quality of life in patients with advanced tumors.Methods 70 patients with advanced tumors were randomly divided into the observation group and the control group,each group had 35 cases.The control group was given conservative treatment,together with the ordinary liquid,semi-liquid or diet.The observation group was given nutrition support therapy on the basis of conservative therapy.The nutrition and immune index and symptom score,quality of life were compared between the two groups.Results The nutrition,immune indexes (Alb,BMI and NK) and symptom score (malaise,anorexia,insomnia,pain) of the observation group were significantly improved(t =7.92,6.98,5.56,7.41,6.47,5.61,4.52,all P ＜ 0.05),which were significantly better than those of the control group(t =4.42,4.10,4.03,6.42,5.60,4.83,4.23,all P ＜0.05).The physical function,role function,emotional function,cognitive function score and total score of the observation group were significantly higher than those of the control group,the differences were statistically significant (t =8.12,6.08,5.12,4.78,4.32,all P ＜ 0.05).Conclusion Nutrition support therapy can improve the nutritional status of cancer patients in advanced stage,relieve symptoms,improve immune function and quality of life,which is worthy of clinical application.

Renal fibrosis is the final common pathway for all kinds of chronic kidney diseases to end-stage renal diseases. Angiotensin Ⅱ plays an important role in the process of renal fibrosis. How to block angiotensin Ⅱ has been a focus of nephrology. This article reviewed the progress in traditional Chinese medicine against renal fibrosis with angiotensin Ⅱ as research target.

BACKGROUND:Studies have shown that as a regulator of bone marrow functionerythropoietinis a glycoprotein that controls the development of the central nervous system and has neurotrophic and neuroprotective potential. Therefore, transplantation of human amniotic mesenchymal stem cels geneticaly modified by human erythropoietin is a new choice for brain injury treatment.
OBJECTIVE:To observe the effect of transplantation of human amniotic mesenchymal stem cels geneticaly modified byhuman erythropoietin on the functional recovery from brain injury in rats.
METHODS:Eukaryotic expression plasmid pcDNA3.1 carrying erythropoietin was successfuly constructed and transferred into amniotic mesenchymal stem cels culturedin vitro. Expression of erythropoietin was detected using western blot assay before and after transfection. Rat models of middle cerebral arterial occlusion was made and given transplantation of transfected amniotic mesenchymal stem celsviathe tail vein (transfection group). Additionaly, model and simple cel transplantation groups were set in a comparative study.
RESULTS AND CONCLUSION:Findings from western blot detection showed that transfected cels could express human erythropoietin. Compared with the other groups, modified neurologic severity scores, growth-associated protein 43 and aquaporin 9 at mRNA and protein levels were al decreased significantly in the transfection group. Furthermore, the number of cels positive for CM-Dil was highest in the transfectiongroup, folowed by simple cel transplantation group, and lowest in the model group (alP<0.05). Overal findings from this study show that human erythropoietin-modified human amniotic mesenchymal stem cel transplantation promotes neurologic recoveryfrom brain injury through eliciting a reduction in growth-associated protein 43 and aquaporin 9 at mRNA and protein levels as wel as inhibiting cel apoptosis.

Objective Through detected the expression degree of Lin28b in three different malig-nant degree pancreatic cancer cell lines and human pancreatic cell line to study the relationship of pancreatic cancer and the express of Lin28b.Methods The RT-PCR was used to detect the expression degree of mR-NA in Lin28b in cell lines of PANC-1,BxPC-3,AsPC-1,HPC-Y5 and Western-blot was used to detect the expression degree of protein in Lin28b in cell lines of PANC-1,BxPC-3,AsPC-1,HPC-Y5,then discovering the differential expression.Results The Lin28b was high expression in three pancreatic cancer cell lines, also higher than human pancreatic cell lines,and the expression of difference had statistical significance. Conclusions The results suggested that Lin28b may play a role in the pathogenesis of pancreatic cancer, and there is a certain relationship between the expression of Lin28b and malignant degree of tumor cells.

[ABSTRACT]AIM:ToobservetheeffectofthesignalingpathwayofproteinkinaseC(PKC)-nuclearfactor-ery-throid 2-related factor 2 (Nrf2) on the expression of heme oxygenase-1 (HO-1) induced by cigarette smoke extract (CSE) in the rat airway epithelial cells .METHODS:After exposed to CSE , the airway epithelial cells of male SD rats were di-vided into control group , CSE3 group, RO318220 group, Nrf2 siRNA group and RO318220+Nrf2 siRNA group.The pro-tein levels of HO-1, Nrf2 and PKC were semi-quantified by Western blotting .The protein expression of HO-1 was assessed by immunocytochemistry .The mRNA expression of HO-1 was detected by reverse transcription-polymerase chain reaction ( RT-PCR) .Nrf2 protein location was observed by immunofluorescence staining .HO-1 activity was also determined .RE-SULTS:After exposure to CSE for 3 h, the Nrf2 protein was mainly located in the nucleus , and the expression level of Nrf2 protein in the nucleus was stronger than that in the control cells .CSE also significantly enhanced the levels of p-PKC protein, and HO-1 mRNA, protein and activity .Pretreatment with RO318220 significantly decreased the levels of PKC pro-tein, Nrf2 protein, and HO-1 mRNA, protein and activity.Meanwhile, Nrf2 protein significantly decreased , and the activ-ity, mRNA and protein levels of HO-1 were also significantly attenuated by pretreatment with siRNA to knock down Nrf2. Pretreatment with RO318220 and Nrf2 siRNA significantly decreased the PKC protein , Nrf2 protein, and HO-1 mRNA, protein and activity .CONCLUSION:CSE up-regulates the HO-1 expression through PKC-induced nuclear translocation of Nrf2 in the rat airway epithelial cells .

BACKGROUND:Although core decompression can contribute to the reconstruction of necrotic bone, its single use appears to have some deficiencies and cannot completely realize the reconstruction of the femoral head.
OBJECTIVE:To explore the effect of arthroscopic core decompression with autologous bone marrow induction material combined with titanium rod in the repair of stage II femoral head necrosis
METHODS:A retrospective analysis was performed on clinical data of 79 cases of stage II femoral head necrosis admitted at the South Branch of Tongchuan People’s Hospital from February 2011 to February 2013. According to the therapeutic methods, these cases were divided into control group (40 cases) and observation group (39 cases), and were given conventional core decompression and arthroscopic core decompression with autologous bone marrow induction material combined with titanium rod. Patients were fol owed up for 24 months, and the range of hip flexion and Harris scores on hip function and adverse events were observed and compared between two groups.
RESULTS AND CONCLUSION:Al the 79 patients successful y completed the 24-month fol ow-up. By the last fol ow-up, the range of hip flexion and Harris score were significantly higher in the observation group than the control group (P<0.05). There was no failure case due to surgical material rejection. To sum up, arthroscopic core decompression with autologous bone marrow induction material combined with titanium rod is safe and effective for repair of stage II femoral head necrosis.

Transcription factorhypoxia inducible factor -1(HIF-1)plays a key role in cell adaption to hypoxia(from 21%O2 to 1%O2).Researches have shown that HIF -1 is closely related to occurrence and de-velopment in many malignant cancers .In this paper,we review the effect of HIF -1 in tumor growth,metastasis, apoptosis and angiogenesis .
