Objective To investigate any anti-inflammatory and curative effect of hyperbaric oxygen (HBO) therapy on mice with acute lung injury (ALI) induced by lipopolysaccaride endotoxin. Methods Fortysix Sprague-Dawley rats, half male and half female, were randomly divided into a normal saline group with 10 rats,an LPS group with 12 rats, and an HBO group with 24 rats. LPS was injected via the tail vein at 5 mg/kg weight to establish the ALI model. The HBO group rats were treated with HBO. Then leucocyte counts, arterial blood gas analysis, interleukin-8 (IL-8) in the blood and lung wet/dry weight (W/D) were compared among the 3 groups at the 3rd and 6th hours. Pathological changes were examined under a light microscope. Results Compared with the LPS group, blood oxygen and W/D were higher in the HBO group, the white blood cell, neutrophil and IL-8 all were lower, and inflammatory cell infiltration was less in lung slides from the HBO group. Conclusions HBO therapy can improve oxygen deficiency and has an anti-inflammatory effect. As a result it might have protective effect against ALI.

Objective To investigate the expression and clinical value of miRNA -22 in gastric cancer tissues.Methods Real -time PCR was used to detect the miRNA -22 expression in gastric cancer tissues and matched adjacent tissues.The correlations of miRNA -22 expression with clinic pathological features were analyzed. Results 87.5%(77 /88)of the gastric tumor tissues showed aberrant down regulation of miRNA -22 compared with adjacent non -tumor tissues (χ2 =69.32,P <0.05).Lower miRNA -22 level was strongly associated with T3 -T4 stage (χ2 =64.38,P <0.05)and lymph node metastasis(χ2 =68.56,P <0.05).The correlation statistical analysis results indicated that there were no significant differencec in sex,age and differentiation grade (all P >0.05 ). Conclusion The lower expression of miRNA -22 is associated with clinic pathological features.

ObjectiveTo elucidate the association between aquaporins (AQPs) expression in kidney tissue and edema of nephrotic syndrome(NS) patients.MethodsNS patients were divided into edema group (14 cases) and non-edema group (8 cases).Ten patients without NS were used as control group.Expressions of AQP1,AQP2,and AQP4 in renal tissues of 3 groups were detectedbyimmunohistochemistrywithstandardtechniquesandsemi-quantitativeanalysis.Association between AQPs expression and edema was examined.ResultsThe positive index of AQP1 expression in proximal tubules in edema group was 0.0373±0.0110,which was significantly lower as compared to non-edema group (0.0510±0.0120) and control group 0.0574±0.0100),while the difference between non-edema and control groups was not significant.The positive index of AQP1 expression in glomerulus was 0.0106±0.0037 in edema group,which was significantly higher than that in non-edema group(0.0021±0.0013) and control group(0.0020±0.0012),while no significant difference was found between the last two groups.AQP2 mainly localized in the collecting duct system.The positive indexes of AQP2 expression were 0.0498±0.0081,0.0370± 0.0072 and 0.0255±0.0103 in edema group,non-edema group and control group,respectively.The differences were significant among 3 groups.AQP4 expression was not found in the renal cortex and collecting duct system.ConclusionsAQPs expression is different in renal tissues of NS patients.AQP2 may play an important role in the edema of NS patients,and AQP1 may involve in the occurrence of edema.

Objective To report the clinical results and the advantages/disadvantages of anterolateral thigh flap (ALT) and forearm flap (FAF) in reconstruction of head and neck defect after cancer ablation. Methods 20 FAFs and 12 ALTs were performed to repair the head and neck tumor ablation defects. Of the 20 FAFs, 7 were used for repair of the through and through buccal defects, 4 for circumferential bypopharyngeal defects, 2 for plate defects, 1 for parotid area skin defect, 4 for floor of the mouth defects, and 2 for defect, of the base of the tongue, while of the 12 ALTs, 3 were used for repair of the defects of the base of the tongue, 4 for plate defects, and 5 for the floor of the mouth and/or lower gum defects. Survival of the flaps, function of the recipient site, and impact to the donor site were compared between these two groups to analyze the advantages/disadvantsges and key technique details of these two flaps. Results 19 FAFs totally survived. Vascular crisis occurred in 2 cases of FAF, of which 1 flap survived after conservative treatment, while the other 1 developed partial necrosis. All the 12 ALTs survived, without vascular crisis. 2 of the 14 planed ALTs were abandoned and replaced by FAFs, of which 1 because of absence of the perforating branch and the other 1 because of injury of the perforating branch. Secondary defects of the ALTs could be closed primarily, while secondary defects of the FAFs should be closed with skin grafts. Conlusion Both ALT and FAF can be performed with high survival rate. Each has its own advantages. Selection of the donor site deponds on situation of the defect and purpose of the reconstruction.

Objective To observe the effect of spleen-warming and kidney-tonifying therapy on Toll-like receptor 4 (TLR4) signaling pathway of cerebral infarction sequelae patients. Methods A total of 60 cerebral infarction sequelae patients with spleen and kidney(yang) deficiency were divided into control group and treatment group, 30 cases in each group. The two groups were given function rehabilitation training following by the theory of modern rehabilitation medicine, and additionally the treatment group was treated with spleen-warming and kidney-tonifying herbs orally. The treatment period for the two groups averaged 3 months. Before and after treatment, the scores of traditional Chinese medicine (TCM) symptoms and signs, peripheral blood TLR4 mRNA expression level, and the inflammation-related factors in the two groups were observed, and the observation parameters were compared with 30 healthy volunteers. Meanwhile, the changes of modern rehabilitation evaluation indexes were also evaluated before and after treatment. Results (1) After treatment, the Fugl-Meyer scores for motor function and Modified Barthel Index(MBI) scores for activities of daily living in the treatment group were obviously increased(P < 0.05 or P < 0.01 compared with those before treatment); the MBI scores in the control group was much increased(P < 0.05 compared with those before treatment), but the Fugl -Meyer scores only showed an increasing trend(P > 0.05). (2) After treatment, the predominant symptoms and signs of hemiplegia, facial distortion and dysphasia in the two groups were much improved(P < 0.01 compared with those before treatment), and the improvement in the treatment group was superior to that in the control group(P < 0.05). The control group had no significant effect on relieving the symptoms and signs of dizziness and blurred vision, numbness of limbs, spontaneous sweating, shortness of breath and weakness, and darkish tongue(P > 0.05 compared with those before treatment); the treatment group had obvious effect on the above symptoms and signs, and the effect was superior to that in the control group(P < 0.05 or P < 0.01).(3) For the inflammation-related factors, tumor necrosis factor alpha(TNF-α) level in the treatment group was much decreased and even arrived to the normal level(P > 0.05), and TNF-α level in the control group was decreased but did not arrive to the normal level(P < 0.05); levels of interleukin(IL)-1β, IL-6 and TLR4 mRNA in the two groups were decreased but did not arrive to the normal(P < 0.01), and the decrease in the treatment group was superior to that in the control group(P < 0.05 or P < 0.01). (4) During the treatment period, no obvious adverse effect was found in the two groups. Conclusion Oral use of spleen -warming and kidney –tonifying Chinese medicine combined with modern rehabilitation therapy is effective for the treatment of the sequelae of cerebral infarction patients by relieving the clinical TCM symptoms, and one of the therapeutic mechanisms is probably related with the TLR4 signaling pathway through regulating the expression of inflammatory factors.
