Objective: To screen the changes of immune-associate genes expression which is related with the ageing using cDNA microar-ray.Methods:The mRNA from the spleens of young and aged rats were extracted respectively and reversely transcribed to cDNAs with the incorporation of different fluorescent-labeled dUTP as the hybridization probes. The mixed probes were hybridized to the cDNA microarray that contains the cDNA products of 416 immune-associated genes. After high-stringent washing, the cDNA microarray was scanned for the fluorescent signals and showed the gene expression differences between the young and the aged. Some biochemical assays were used to confirm the physiological differences between the young rats and the aged rats. Results: Among the examined genes, 13 down-regulated genes were identified. These genes correlated with immuned response, cell proliferation, cell differentiation and DNA/RNA repair. Only one gene which encoded ?-amylase was much higher in the aged than that in the young. Conclusion: Further analysis of the differenially expressed immune-associated genes based on cDNA microarray will be helpful for understanding the molecular mechanism of the ageing.

Purpose To detect whether a 3243 point mutation existed in age related macular degeneration (AMD). Methods Twenty six cases of wet form AMD patients, ten cases of dry form AMD patients were selected,and compared with twenty nomal controls. After collecting anti coagulated blood samples, total cellular DNA were extracted and purified. Using polymerase chain reaction and restriction fragment long polymorphism techniques, the mtDNA A→G point mutation at position 3243 were detected. Results After cleaveded by restriction endonuclease Apa I, a 294 bp fragment remained only in all detected DNA samples including twenty six wet form AMD, and ten dry form AMD. No any other fragment appeared. The result showed that there was no A→G mutation at position 3243 found in AMD. Conclusion It is suggested that mtDNA 3243 point mutation due to maternal inheritance might be not concerned with both wet form AMD and dry form AMD.

ObjectiveTo discuss the clinical efficacy of distal medial arm perforator flaps.MethodsAccording to the basic anatomy of distal medial arm perforator flaps,the distal medial arm perforator flaps were designed for repairing skin defects around elbow joints and at upper part of forearms in 15 cases.ResultsAll flaps were survived and first intention of wounds was obtained.At 3-36 months of follow-up,flap shape and elbow joint function revealed satisfactory recovery.Conclusions With the constant anatomical position,good blood supply,safe surgical approaches and cryptic donor site,the distal medial arm perforator flap is an alternative to repair the skin defects around elbow joints and in proximal forearms.

The challenge of the emergence of drug-resistant influenza strains, which is caused by wide spread utilization of direct-acting antivirals (DAAs), accelerates the research and exploration towards host targeted agents. In contrast to DAAs targeting viral replication components, host targeted agents, which regulate host factors and pathways linked to viral replication, can interfere the replication of influenza. Additionally, the innate immune system is activated by influenza during the early stage of infection, so manipulating the innate immune response may prevent the viral infection. However, the excessive inflammatory response induced at the late phase of influenza infection would lead to severe tissue injures. Thus, it is very important to explore drugs with anti-inflammatory actions to suppress these immune imbalances and tissue injures. Here we overview the current progresses about host targets related to anti-influenza drugs.

OBJECTIVETo investigate the changes in the levels of monocarboxylate transporter-2 in spinal cord horn in a rat model of chronic inflammatory pain.
METHODSMale SD rats weighting 180 - 220 g were randomly divided into two groups(n = 48): normal saline group (NS group), complete Freund's adjuvant group (CFA group). Rats were given injections of CFA 100 µl in left hind paw in group CFA, and an equal volume of saline was given injection in group NS. Mechanical withdraw threshold(MWT) and thermal withdraw latency(TWL) were measured at before injection(T0 and 3 h, 1 d, 3 d, 7 d, 14 d, and 21 d after injection(T1-7). Four rats were chosen from each group at T0-7 and sacrificed, and L4-5 segments of the spinal cord horn were removed for measurement of the expression of monocarboxylate transporter-2 by Western blot analysis.
RESULTSIn CFA group, mechanical hyperalgesia and allodynia appeared on the 3 h after CFA injection, then until the day 14. The expression of monocarboxylate transporter-2 in the spinal dorsal horn of rats in CFA group was significantly higher than that in normal control group at T1-6(P <0.05). The protein level of monocarboxylate transporter-2 was apparently correlated with MWT and TWL(P <0.01 and P <0.05) in CFA group.
CONCLUSIONThe level of monocarboxylate transporter-2 in spinal dorsal horn is significantly increased in a rat model of chronic inflammatory pain and the change may involve in the formation and maintenance of central sensitization in spinal cord of chronic inflammatory uain.
