OBJECTIVETo investigate the tumor proliferation and apoptosis changes after preoperative hepatic and regional arterial infusion chemotherapy (PHRAIC) after radical colorectal cancer resection.

METHODSFive hundred and nine patients with stage II or stage III colorectal cancer from June 2001 to June 2007 were randomly assigned to PHRAIC group (n = 256) or control group (n = 253, surgery alone). Tumor proliferation and apoptosis index were evaluated in tumor tissues of the control and PHRAIC group (pre and after intervention). The survival rates were also recorded in the two groups.

RESULTSThere was no significant differences in sex, age, tumor location, tumor size, tumor stage, tumor differentiation and follow-up time for the two groups (P > 0.05). There was no significant differences in all the evaluation factors between the control group and PHRAIC group before intervention (P > 0.05). Before and after intervention for PHRAIC group: stage 3 necrosis rate were 3.1% and 22.7%, stage 4 necrosis rate were 0 and 13.5% (P < 0.05); label index of Ki67 were 48.6 +/- 17.1 and 38.4 +/- 13.3 (P < 0.05); expression rate of Bax, bcl-2 and survivin were 48.0% vs 77.0%, 75.0% vs 43.0%, 52.0% vs 31.6%, respectively (P < 0.05); apoptosis rate were 4.3% +/- 2.2% and 16.7% +/- 6.4%(P < 0.05). In the PHRAIC group, 42.1% +/- 11.2% of the cells in the tumor tissue were in S phase before intervention and the rate fell to 21.8% +/- 10.7% after intervention (P < 0.05); and G0-G1 phase rate of the group pre and post intervention were 35.1% +/- 12.1% and 57.1% +/- 18.1% (P < 0.05). All the patients were followed-up for a mean time of 42 +/- 14 months. For patients with stage III tumor in PHRAIC group and control group, the 5-year liver metastasis rate were 18.9% and 27.3% (P = 0.033), recurrence and metastasis rate were 26.3% and 38.0 (P = 0.024), overall survival rate were 81.0% and 60.4% (P = 0.011), median survival time were 45 and 40 months (P = 0.02); no significant differences of aforementioned factors was found in patients with stage II tumors between the two groups.

CONCLUSIONThe schedule of preoperative hepatic and regional arterial infusion chemotherapy before surgery can restrain proliferation, promote apoptosis and reduce liver metastasis and improve survival rate in stage III colorectal cancer.

Objective To investigate the effect of glutamine (Gln) on the content of reduced glutathione hormone (GSH) and aminoglutaminic acid (Glu) of spinal cord following ischemia-reperfusion injury. Methods Totally 40 healthy adult male rabbits were randomly divided into five groups: sham-operation group (S group), ischemia-reperfusion injury group (I/R group), low-dose glutamine group (L Gln group), median-dose glutamine group (M Gln group) and high-dose glutamine group (H Gln group). After glutamine preconditioning, the model of spinal cord ischemia-reporfasion injury was established according to Zivin's method. The general status of animals was observed and the changes of Jacobs scoring were recorded in each group. Malondialdehydes (MDA), GSH, Glu and superoxide dismutase (SOD) activity in lumbar spinal cord tissues were determined using chemical colorimetry. The neuron number and deviation rate in spinal cord anterior horn were observed histopathologically. Results There was no significant difference between L Gin group and I/R group in behavior scoring, SOD activity, content of MDA and Glu, neuron number and deviation rate of spinal cord (P>0.05); however, there was a significant difference in GSH content of spinal cord (P<0.05). M Gln group and I/R group differed significantly (P<0.05) in behavior scoring, SOD activity, content of MDA, Glu, GSH, neuron number and deviation rate of spinal cord. Between H Gln group and M Gln group, there was no significant difference in behavior scoring, content of MDA and Glu, SOD activity, neuron number and aberration rate in spinal cord (P>0.05), whereas there was a significant difference in SOD activity and Giu content (P<0.05). Conclusion Pretreatment with medium-dose glutamine has a protective effect on spinal cord ischemia-reporfasion injury in rabbits, which may be related to the maintenance of GSH content, increase of SOD activity and reduction of MDA.

OBJECTIVETo study the expression profile of microRNAs (miRNAs) in peripheral T cell lymphoma, not otherwise specified (PTCL-NOS) and to explore the underlying molecular characteristics.

METHODSTwenty-one cases of PTCL-NOS were enrolled into the study. The tumor presented either as nodal (15/21) or extranodal (6/21) disease. TaqMan low density array was used to assess the expression level of 754 miRNAs in six cases of PTCL-NOS and three control cases of reactive lymphoid hyperplasia. Prediction of target genes for significant and differential expression of miRNAs was carried out using Targetscan and miRanda software. Bioinformatics tools were employed for GO-Analysis and Pathway-Analysis of target genes. The expression patterns of the three miRNAs were further analyzed in the remaining 15 cases of PTCL-NOS and 10 cases of reactive lymphoid hyperplasia, using single tube Taqman miRNA assays.

RESULTSEight miRNAs showed statistically significant difference in expression between PTCL-NOS and reactive lymphoid hyperplasia. miR-886-3p, miR-511, miR-1291, miR-572, miR-27a-3p, miR-25-3p and miR-886-5p were significantly overexpressed in PTCL-NOS while miR-182-5p was significantly underexpressed (P < 0.05). Target gene prediction showed that 1646 candidate genes involved in the pathogenesis and progression of PTCL-NOS. Further GO and Pathway-Analyses found that these genes significantly focused on 63 GO terms and 61 pathways. The results of three miRNA qRT-PCR confirmed that miR-572 and miR-1291 expression in PTCL-NOS had statistical significance.

CONCLUSIONSEight miRNAs are aberrantly expressed in PTCL-NOS, which may be involved in molecular regulation during the development of PTCL-NOS. The underlying mechanism is also related to a number of target genes and signaling pathways.

OBJECTIVE: To detect the changes of mitochondrion DNA (mtDNA) sequence in articular chondrocytes of cartilage affected by osteoarthritis and to clarified the pathogenetic mechanism of osteoarthritis. METHODS: We analyzed the mtDNA 4,977 bp deletion mutations of articular chondrocytes in 10 patients with osteoarthritis and 3 normal cartilages using the gap-PCR amplification method. We designed a two round PCR detection method, in which total DNA was isolated from articular chondrocytes as the template of the first round PCR reaction and products from the first round were the template in the second round reaction. RESULTS: The results of the first rounds of PCR reaction showed the mtDNA 524 bp amplified products in the osteoarthritis group and in the corresponding peripheral blood samples were not detected, but the 533 bp products were detected. However,the results of the second round reaction revealed that the 524 bp zones were detected in 2 of the 10 osteoarthritis patients and the corresponding peripheral blood samples were not detected. The 533 bp products were detected in all specimens. The mtDNA 524 bp amplified products in all the normal articular chondrocytes and the corresponding peripheral white blood cells contrast were not detected in both rounds PCR. CONCLUSION This was the first study to evaluate the mtDNA 4799 bp large fragment deletion mutational accumulation between nt8,470 - nt13,447 of articular chondrocytes in osteoarthritic cartilage. Osteoarthritis may be related to mtDNA mutation of articular chondrocytes.

OBJECTIVE: To evaluate the therapeutic effects of intraarticular injection of ligustrazine on knee osteoarthritis (OA). METHODS: Seventy-one cases of knee osteoarthritis (82 knees) were randomly divided into ligustrazine (LI) group and sodium hyaluronate (SH) group. The patients were intraarticularly injected ligustrazine or sodium hyaluronate once a week for 5 consecutive weeks, and were followed-up for 3 months. Lequesneos protocol for the evaluation of OA severity and activity was used. The therapeutic effects and changes of Lequesneos index were observed after the treatment. RESULTS: There was significant decrease in Lequesneos index in SH group after the treatment (P<0.01), but not in LI group (P>0.05). Three weeks later, there was significant decrease in Lequesneos index in both groups after the treatment (P<0.01), with no significant difference between SH and LI group (P>0.05). After the 5-week treatment, the efficacy rate of the LI group was 82.1%, and that of the SH group was 87.2%. No serious toxic or side effect was observed during the treatment and the follow-up. CONCLUSION Intraarticular injection of ligustrazine has a therapeutic effect on knee OA. No adverse effect is observed, but it needs long time to take effect.

OBJECTIVETo investigate the effect of transurethral resection of the prostate (TURP) in the treatment of advanced prostate cancer with bladder outlet obstruction (BOO).

METHODSWe included in this study 43 cases of advanced prostate cancer with BOO treated by TURP, and analyzed their IPSS, maximum urinary flow rate and relevant risk factors pre-operatively and at 3 and 12 months after TURP.

RESULTSCompared with the baseline, IPSS and the maximum urinary flow rate of the patients showed significant differences 3 months after surgery ([19.60 +/- 0.41] score vs. [9.58 +/- 0.33] score, [4.93 +/- 0.68] ml/s vs. [8.96 +/- 0.47] ml/s, P < 0.05), but not at 12 months ([15.73 +/- 0.66] score, [5.67 +/- 0.44] ml/s). In multiple regression analysis, a good outcome was associated with pre-operative acute urinary retention, while poor prognosis with hormone-refractory prostate cancer.

CONCLUSIONIn the treatment of advanced hormone-refractory prostate cancer with BOO, TURP can reduce IPSS and increase the maximum urinary flow rate in the early period after surgery, but its long-term effect is not so desirable. Meanwhile the operation itself may bring about relevant complications and reduce the patient's quality of life.

Chronic kidney disease (CKD) is a major public health problem that affects about 10% of the general population. Current approaches to characterize the category and progression of CKD are normally based on renal histopathological results and clinical parameters. However, this information is not sufficient to predict CKD progression risk reliably or to guide preventive interventions. Nowadays, the appearance of systems biology has brought forward the concepts of "-omics" technologies, including genomics, transcriptomics, proteomics, and metabolomics. Systems biology, together with molecular analysis approaches such as microarray analysis, genome-wide association studies (GWAS), and serial analysis of gene expression (SAGE), has provided the framework for a comprehensive analysis of renal disease and serves as a starting point for generating novel molecular diagnostic tools for use in nephrology. In particular, analysis of urinary mRNA and protein levels is rapidly evolving as a non-invasive approach for CKD monitoring. All these systems biological molecular approaches are required for application of the concept of "personalized medicine" to progressive CKD, which will result in tailoring therapy for each patient, in contrast to the "one-size-fits-all" therapies currently in use.

OBJECTIVETo assess the clinical efficacy and the safety for periarthritis of shoulder treated with deep puncture by elongated needle combined with spike-hooked needle and cupping.

METHODSA multicentral randomized controlled study was adopted. One hundred and twenty cases were divided into an observation group and a control group, 60 cases in each one. In observation group, elongated needle, spike-hooked needle and cupping were used to stimulate Jianyu (LI 15), Naoshu (SI 10), Naohui (TE 13) and Jianqian (Extra). In control group, a conventional needling and cupping were applied to the same points as observation group. Visual Analogue Scale (VAS) and Melle evaluation for the function activity of shoulder joint were adopted to assess and compare the efficacy on analgesia and the effect on shoulder joint range of motion before and after treatment in two groups.

RESULTSIn observation group, the cured and markedly effective rate of analgesia was 91.7% (55/60), which was obviously better than 20.4% (12/59) in control group (P < 0.001). Concerning to the improvements of the range of motion in shoulder joint, the cured and markedly effective rate in observation group was 91.7% (55/60), which was better than 18. 6% (11/59) in control group (P < 0.001). VAS score and Melle score after treatment were apparently improved as compared with those before treatment in two groups (all P < 0.001). The improvements in observation group were superior to those in control group (both P < 0.001). There was no adverse event reported during the treatment in two groups.

CONCLUSIONThe deep puncture by elongated needle combined with spike-hooked needle and cupping achieves a significant clinical efficacy on periarthritis of shoulder and has no adverse reaction reported.
