Objective To study the expression of P73 and its relationship with expression of Survivin in colon carcinoma. Methods The expression of P73 and Survivin was studied by immunohistochemical technique in 46 cases of colon carcinoma and 12 cases of normal colon mucosa. Results The P73 expression rate of colon carcinoma was significant higher than that of normal colon mucosa(χ2 = 13.42, P ＜0.01 ). Overexpression of P73 was related to the pathological grade and Dukes stage ( ( χ2 = 8.01, P ＜0.01 ), and it was closely related to lymphatic metastasis of colon carcinoma( P ＜0.01 ). There was a positive relation between P73 and Survivin( rs =0.487, P ＜0.01 ). Conclusions The expression of P73 was closely associated with Survivin in colon carcinoma. The results suggested that the overexpression of P73 and Survivin was involved in the tumorigenesis and development of colon carcinoma and P73 and Survivin might be used as a new tumor marker in metastasis and prognosis of colon carcinoma.

Objective To develop a simple and quick method for detection of stress-induced 5′transfer RNA( tRNA) halves.Methods Total RNA purified from stress induced cells was polyadenylated by poly( A) polymerase, and then degen-erate DNA probes were used to hybridize with 3′tRNA-halves of intact tRNAs,while RNase H specifically degraded the 3′tRNA-halves strand in tRNA-DNA probes hybrids.Using the RNase H digestion total RNA as templates, complementary DNA( cDNA) was synthesized by oligo ( dT) n-anchored primers.The primer of 5′tRNA halves and anchored-primer were used to amplify 5′tRNA halves by PCR.Results The results showed that the method of poly ( A )-tailed-RNase H digestion-RT-PCR could be successfully used to detect stress-induced 5′tRNA halves.Conclusion A simple and quick method for detection of 5′tRNA halves has been established,which is a user-friendly tool for 5′tRNA halves detection and function research.

Objective To investigate the level of nurses′preparedness and influencing factors of nurses with low seniority in Anhui province. Methods Totally 295 nurses with low seniority were recruited by convenience sampling method. They were investigated by a self-designed demographic data questionnaire and the Disaster Preparedness Evaluation Tool. Results The score of the disaster nursing ability of the nursing managers was 163.85 ± 32.41, the mean score was 3.64 ± 0.72. Regression analysis showed that the gender, the experience of disaster rescue,disaster training were the influencing factors of disaster preparedness. Conclusions The capacity of disaster preparedness for nurses is not ideal. There is still room for improvement among nurses in Anhui province to enhance disaster preparedness, and improved disaster nursing training system is needed to achieve this.

Objective To explore the risk factors of surgical treatment for children’ s tethered cord syndrome. Methods Retrospective-ly analyzed the clinical data of 43 tethered cord syndrome children who had undergone surgical treatment from January 2007 to December 2009,and to evaluate the efficacy of the surgical treatment. Meanwhile,The Cox proportional hazards regression model was adopted to evaluate the surgical efficacy. Results 28 children received effctive curative effect after the surgical treatment in 43children with tethered cord syn-drome,the total effective rate was 65. 12%. Cox medol showed that tight filum terminale(P<0. 05), operation methods (P<0. 05)and the duration of the disease(P<0. 05)were independent risk factors of surgical treatment for children’s tethered cord syndrome. Conclusion The operativeefficacy of children’ s tethered cord syndrome were influence by the tight filum terminale,operation methods and the duration of the disease.

Objective To investigate the expression of interleukin-6 (IL-6) and its role in incisional pain in the rat model.Methods Incisional pain rat model was established by a longitudinal incision in right plantar hind paw of isoflurane-anesthetized rats.Spinal cords were removed at various postoperative times (1,6,24,72 h).The gene expression of IL-6 in the spinal cord was determined by a Real-time PCR.Immunohistochemistry and double-labeling immunofluorescence were performed to determine the expression of IL-6 after incision.Intrathecal injection of IL-6 antibodies was performed to modulate the spinal IL-6 after surgical incision,and the mechanical hypersensitivity was assessed by paw withdrawal thresholds from mechanical stimuli of von Frey filaments.Results After hind-paw incision,the IL-6 mRNA level was upregulated in the ipsilatcral lumbar spinal cord.The immunoreactivity of IL-6 in spinal cord was increased after hind-paw incision at 6 hours after incision.The upregulated spinal IL-6 was mainly localized in the neurons and endothelial cells.Intrathecal injection of IL-6 antibodies dramatically inhibited the surgical incision that evoked pain hypersensitivity.Conclusions The present study showed that the upregulated IL-6 in the spinal cord contributed to the pain hypersensitivity after surgical incision,inhibiting the upregulated IL-6 in the spinal cord may be a possible new therapeutic target for the treatment of postoperative pain.

OBJECTIVETo evaluate the short-term and long-term effects on treatment of neck pain caused by cervical spondylosis with the combination of acupuncture and moxibustion with seed-size moxa cone.

METHODSOne hundred and forty-five patients of neck pain were randomly divided into an acupuncture-moxibustion group (49 cases), an acupuncture group (48 cases) and a moxibustion group (48 cases). Acupoints of Bailao (Extra), Dazhui (GV 14), Jianzhongshu (SI15) and Zhongzhu (TE 3) were adopted for all the 3 groups. Acupuncture was applied at all the acupoints with 20 min needling retention for the acupuncture group. Moxibustion with seed-size moxa cone was used with 5 cones on each point for the moxibustion group. And both acupuncture and moxibustion with seed-size moxa cone were adopted for the acupuncture-moxibustion group. The treatment was applied once every 3 days, and 10 treatments should be finished within 4 weeks. Follow-up should be carried out for 3 months. The short-term and long-term effects were evaluated with the scores of Northwick Park Pain Questionnaire (NPQ) and McGill Pain Questionnaire (MPQ) as the indices of therapeutic effect.

RESULTSThe NPQ score and MPQ score of all the 3 groups after the treating course and the 3-month follow-up were both decreased when compared with those before the treatment (all P<0. 05). The scores of NPQ and MPQ the acupuncture-moxibustion group were lower than that of the other two groups. And the difference had obvious significance (P<0. 05). High efficiency of pain relieving for cervical spondylosis could be found in all the 3 groups, which showed that short-term and long-term effects were good for all the 3 groups. And the highest curative effect could be found in acupuncture-moxibustion group.

CONCLUSIONCombination of acupuncture and moxibustion with seed-size moxa cone has reached a superior effect in short-term and long-term for neck pain caused by cervical spondylosis.

Protein-coding transcriptome,pseudogenes,long non-coding RNAs and circular RNAs can act as competing endogenous RNA (ceRNA).ceRNA can crosstalk with each other through microRNA recognition elements (MRE),thus regulating the post-transcriptional gene expression.More and more evidences showed that ceRNA could form an extensive network of post-transcription regulation,keep the cell homeostasis and involve in the disease development and progression like tumorigenesis and cancer progression.Depending on up-regulation or down-regulation of different kinds of microRNA in different cells,ceRNA acts as either an oncogene or a tumor suppressor.ceRNA may have a great potential in cancer diagnosis and treatment.

The kinetics of batch and fed-batch cultures of recombinant Escherichia coli to produce humanlike collagen were investigated. Through examining the density of substrate and the amount of mushrooms and the density of products during the process of fermenting, a set of kinetic models are set up. The influence of cell without plasmid was considered. The results show that the kinetic model may well simulate the fermenting process.
