AIM: To evaluate the protection of Mn~(2+) on injury of human kidney tubular epithelial cell line induced by gentamicin, and investigate its principals. METHODS: Gentamicin was used to injury human kidney tubular epithelial cell line (HK-2) to produce model of kidney injury. MTT method was used to measure effect of Mn~(2+) on proliferation of cells after they were injured by gentamicin. The spectrophotometry method was used to observe the change of LDH,NAG and SOD effected by Mn~(2+). Ultrastructure was examined by electron microscopy. RESULTS: Although HK-2 cells were injured, Mn~(2+) promoted cells proliferation, decreased LDH activity and NAG content, increased SOD activity, and alleviated dilation of the mitochondria and crushing of lysosomes. CONCLUSION: Mn~(2+) can protect human kidney tubular epithelial cell line from injury induced by gentamicin. It may be in relation to inhibiting the oxidative injury, lightening dilation of the mitochondria, protecting the integrity of lysosomes and decrease the leakage of enzyme.

AIM: To explore the effects of rheum tanguticum polysaccharides(RTP) on TNBS-induced colitis in mice and its probable mechanisms.METHODS: Mice colitis model was induced by 2,4,6-trinitrobenzene sulfonic acid(TNBS).The mice were randomly divided into 5 groups,normal group,model group,RTP-100,200 and 400 group.The macroscopical and histological changes of the colon were evaluated and the cytokines IL-8,IL-10,TNF-?and IL-4 produced by splenocyts were analyzed with ELISA.RESULTS: Compared with the model group,both symptoms and the lesions of colonic mucosa of RTP-200 and 400 group were slighter on ulcerative colitis induced by TNBS in mice. Furthermore,the expressions of TNF-?and IL-8 in colon tissue of mice with TNBS-induced colitis were higher and the IL-10 and IL-4 were lower than that of normal control(P

Objective To investigate the relationship between single nucleotide polymorphisms of surfactant protein C(SP-C)gene and respiratory distress syndrome(RDS)in the Han nationality newborns in Inner Mongolia and whether there is a mutation occurs on SP-C gene exon 4 and 5.Methods One hundred newborns with RDS(case group)and 100 newborns without RDS(control group)were selected.PCR gene analysis was used to establish the genotype and allele frequencies of exon 4 (T138N)and 5 (S186N)on SP-C.Results In the Han nationality newborns of Inner Mongolia region,there was no mutation on SP-C gene exon 4 and 5.Exon 4(T138N)on SP-C could be checked out three genotypes:namely AA,AC and CC.The genetic polymorphisms of exon 4 on SP-C were not statistically different between the case group and the control group(χ2 ﹦0.744,P ﹦0.689).Besides,exon 5(S186N)on SP-C could also be checked out three genotypes:namely AA,AG and GG.The genetic polymorphisms of exon 5 on SP-C were also not statistically different between the case group and the control group(χ2 ﹦0.770,P ﹦0.681 ).Conclusion There is no mutation on SP-C gene exon 4 and 5.The genetic polymorphism of exon 4 and 5 on SP-C displays no signifi-cant correlation with RDS of the Han nationality newborns in Inner Mongolia.

Objective: To observe the clinical efficacy of heat-sensitive moxibustion for adjuvant treatment of depression in Parkinson disease and explore its mechanism. Methods: A total of 80 patients with Parkinson disease coupled with depression were randomized into an observation group and a control group, with 40 cases in each group. The control group was treated with levodopa and benserazide hydrochloride tablets and paroxetine tablets, while the observation group was treated with heat-sensitive moxibustion on the basis of the medications in the control group. The treatment course was 2 months. The Hamilton depression scale-17 (HAMD-17), unified Parkinson's disease rating scale (UPDRS) and Parkinson's disease quality of life questionnaire-39 (PDQ-39) were scored before and after the treatment, and the efficacy was evaluated after treatment. Levels of patients' serum dopamine (DA), 5-hydroxytryptamine (5-HT), tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were detected before and after the treatment. Results: After treatment, the total effective rate of the observation group was higher than that of the control group (P<0.05). The HAMD-17 scores in the two groups decreased significantly after treatment (both P<0.05), and the score in the observation group was obviously lower than that in the control group (P<0.05). The component scores and total scores of UPDRS in both groups decreased significantly (all P<0.05), and the scores in the observation group were lower than those in the control group (all P<0.05). The score of PDQ-39 in the observation group decreased significantly (P<0.05), and was lower than that in the control group (P<0.05). After treatment, the serum DA and 5-HT levels in the observation group increased significantly (both P<0.05) and the TNF-α and IL-6 levels decreased significantly (both P<0.05), which were statistically different from those in the control group (all P<0.05). Conclusion: Heat-sensitive moxibustion has certain auxiliary effect in treating depression in Parkinson disease, significantly improving clinical symptoms and the quality of life, which may be related to the up-regulation of DA and 5-HT levels and down-regulation of TNF-α and IL-6 levels.

ObjectiveTo demonstrate the effect of moderate hypothermia and doule carotid ice applied to acute intracerebral hemorrhage (ICH) and the best opportunity of treatment.Methods174 cases with ICH were randomly divided into treated group and control group, 87 cases for each group. Each case of both groups was treated by routine therapy, moreover, all cases in treated group were treated by moderate hypothermia (MHT).The clinical effect and prognosis between treated group and control group were contrasted,so to do between the cases in the treated group who were treated no more than 3 hours and more than 3 hours after attack.ResultsCompared with the control group, the neurological function improved in the treated group(P<0.05), as well as survival rate and recovery(P<0.05).Cases who treated no more than 3 hours after attack was better than that of more than 3 hours(P<0.05).ConclusionModerate hypothermia can effectively ease the neurologic deficits after ICH, decrease mortality and disable rate.The best therapy time is within 3 hours after ICH.
