BACKGROUND: Glutamine (Gln) supplementation is known to decrease oxidative stress and inflammatory response, enhance resistance to infectious pathogens, shorten hospital stay, and decrease medical costs of patients. This study was undertaken to evaluate the relationship between the effect of early parenteral glutamine (Gln) supplement on acute liver injury (ALI) and heat shock protein 70 (HSP-70) expression in critical patients. METHODS: Forty-four patients who had been admitted to the emergency intensive care unit (EICU) of Nanjing First Hospital Affiliated to Nanjing Medical University were randomly divided into a control group (n=22) and a Gln group (n=22). The patients of the two groups received enteral and parenteral nutrition. In addition, parenteral Gln 0.4 g/kg per day was given for 7 days in the Gln group. Serum HSP-70 and Gln were measured at admission and at 7 days after admission. Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin (TBiL), serum levels of HSP-70 and Gln, mechanical ventilation (MV) time, ICU stay, peripheral blood of TNF-α, IL-6, CD3, CD4 and CD4/CD8 levels were also measured in the two groups. RESULTS: In the Gln group, the levels of serum HSP-70 and Gln were significantly higher after Gln treatment than those before the treatment (P<0.01). HSP-70 level was positively correlated with the Gln level in the Gln group after administration of parenteral Gln (P<0.01). The levels of serum ALT, AST, TBiL and TNF-α, IL-6 were lower in the Gln group than in the non-Gln group (P<0.01). MV time and ICU stay were significantly different between the two groups (P<0.05). The levels of CD3, CD4 and CD4/CD8 were significantly higher in the Gln group than in the control group after treatment (P<0.05). CONCLUSION: Parenteral Gln significantly increases the level of serum HSP70 in critically ill patients. The enhanced expression of HSP70 is correlated with improved outcomes of Gln-treated patients with acute liver injury.

Objective To investigate the relation between the rs2070045 locus polymorphism in the SORL1 gene and the onset risk of AD by means of Metβ-analysis. Methods Databases (Medline, Cochrane Library and CBM) were searched using keywords like SORL1, sortilin-related receptor, Alzheimer and so on, and a manual search of citations was also performed from relevant original studies and literatures. All analyses were conducted with Review Manager Version4.2 software. Results 3 literatures with 11 different ethnic groups were studied, totally including the AD group (2927 cases) and the control (3867 cases). The summary OR for studies with frequency of GG+GT genotype at rs2070045 locus in the SORLI gene was 1.19 (95%CI: 1.08-1.31, Z=3.39, P=0.0007), when it compared with the common homozygote ofTT genotype. The summary OR for allele frequency was 1.17 (95%CI: 1.07-1.27, Z=3.67, P=0.0002). Conclusion The metβ-analysis suggests that the polymorphism at rs2070045 locus of SORL1 gene might be a genetic risky factor for AD.

OBJECTIVETo study the role of nuclear factor (NF)-kappaB pathway with p38MAPK in Curcuma wenyujin diterpenoid compound C (CDCC) fighting against inflammation and inducing gastric cancer cell apoptosis by stimulating gastric cell SGC7901 with tumor necrosis factor-alpha (TNF-alpha).

METHODSHuman umbilical vein endothelial cells (HUVECs) and human gastric cancer SGC-7901 cells were in vitro acted by CDCC in different concentrations at different time points. Their growth inhibition ratios were measured by MTT assay. The apoptosis rate of gastric cancer cells was detected by Annexin V-FITC/PI double staining. Nuclear translocation of p65 was detected by cell immunofluorescence. Expression levels of p38MAPK/P-p38MAPK, p65/P-p65, and Caspase 3/P-Caspase 3 were measured by Western blot.

RESULTSCDCC had significant inhibitory effect on the proliferation of SGC-7901. It also could effectively induce the apoptosis of gastric cancer cell SGC-7901. It also could reduce nuclear translocation of p65 in gastric cancer cell SGC-7901. Results of Western blot indicated that expression levels of p38MAPK and p65 were reduced and the expression level of Caspase-3 was elevated along with increased concentrations of CDCC (P<0.05).

CONCLUSIONApoptosis executive protein Caspase 3 activated by regulating p65 via p38MAPK might be one of possible mechanisms for CDCC fighting against inflammation and gastric cancer.

Objective To explore the clinical characteristics, surgical treatment and related factors of traumatic implantation cyst of the iris. Design Retrospective cases series. Participants Thirty-six cases of traumatic implantation cyst of the iris. Methods Thir- ty-six cases of traumatic implantation cyst of the iris were reviewed. Main Outcome Measures Age, surgical history, history of disease, surgical method of patients. Results All cases of traumatic implantation cyst of the iris were secondary to perforating injury. 10 cases had been undertaken cataract surgery. The histories of disease in 6 months～1 year and 1 year～10 years were 30.56% respectively. Sur- gical exicision was taken in all cases. There were 2 recurrence cases. Conclusion Traumatic implantation cyst of the iris is almost see- ondary to perforating injury. Surgical excision is an effective strategy to treat this disease.

OBJECTIVETo study the effect of dragon's blood powder with different grain size on the transdermal permeability and adhesion of ZJHX paste.

METHODDragon's blood powder with grain sizes of 4, 19, 55 microm were got by ultrafine grinding technology, and then prepared into rubber pastes A, B, C and D, together with dragon's blood powder with grain size of 93 microm of original description. Franz diffusion cell method was adopted to compare the difference in transdermal permeability of dragon's blood powder with different grain sizes, with dracorhodin as the index, and compared their effect on the adhesion of pastes with initial adhesion, permanent adhesion and peel strength as the indexes.

RESULTQ(s)-t equations of pastes A, B, C, D were as follows: Q(s)=1.369 6t + 3.985 5, Q(s) = 1.262 8t +3.738 1, Q(s) = 1.192 3t + 3.320 6, Q(s) = 1.152 2t + 2.366 1, respectively, which showed that the adhesion of A was the best good.

CONCLUSIONWith the decrease in the grain size of dragon's blood powder, accumulative penetration of dracorhodin increases, which facilitates transdermal permeability and adhesion.
