Objective To observe the effect of hyperbaric oxygen on choline acetyltransferase ChAT levels in the neurons of rats with traumatic brain injury. Methods Traumatic brain injuries were modeled in rats using Feeney's method. Thirty male rats were randomly divided into 3 groups: a traumatic brain injury group (group A) , a traumatic brain injury plus hyperbaric oxygen ( HBO) group ( group B) , and a sham operation group (group C). Samples of each rat's brain were tested for ChAT using immunohistochemical staining and light microscopy. Results ChAT-positive fibers in the hippocampus almost vanished after traumatic brain injury, but positive fibers were markedly increased after HBO treatment. Conclusion HBO treatment can activate neurons in the hippocampus and inhibit regression of cholinergic neurons, which may be one of the mechanisms by which HBO therapy improves learning ability in injured rats.

Objective:To analyze the association of type 2 diabetes mellitus(DM) with the clinical and coronary angiographic features of coronary heart disease(CHD) in patients aged over 70 years old.Methods: A total of 310 elderly patients with coronary angiograph-confirmed coronary diseases,who were treated in Changhai Hospital during Apr.2006 to Jul.2008,were retrospectively analyzed.The patients were further divided into 2 subgroups according to the presence of DM: DM-CHD group(n=155) and non-DM-CHD group(n=155).The age,gender,blood pressure,blood lipid,ejection fraction(EF),the angiographic outcomes,etc.were analyzed and compared between the two groups.Results: The incidence of hypertension was significantly higher in the DM-CHD group than in the non-DM-CHD group(P

Objective To establish a new effective method by using real-time polymerase chain reaction (PCR) to detect single nucleotide polymorphism (SNP) typing for rapid identifying apolipoprotein E alleles.Methods To determine alleles of human apolipoprotein E genetic polymorphism at Cys112Arg locus was detected by PCR melting curve analysis with fluorophore SYBR Green I. In order to increase the speciality of SNP assays, high fidelity Taq polymerase was used. The reliability of SNP typing was validated by comparison with the results of direct DNA sequencing.Results Each sample was determined by double tubes, and two melting curves were analysis. As compared the Tm value of samples with the Tm of standard substance, the apoE genotype of samples was determined. The apoE genotype of 30 samples were E3/3 (27/30) and E3/4 (3/30) respectively, which was accordant with the results of PCR-RFLP and DNA sequencing.Conclusion The presented allelic assay was specific, easy to operate and applicable for discrimination of apolipoprotein E genotyping of human blood.

Objective:To compare the clinical value of early enteral nutrition(EEN) with total parenteral nutrition(TPN) in postoperative elder patients with esophageal and cardiac cancer. Methods: 102 cases of postoperative elder patients with esophageal and cardiac cancer were randomly divided into EEN group(n=51)and TPN group(n=51).The weight loss,serum albumin, prealbumin,liver function were measured before operation and on the eighth day after operation. The anal exsufflation time, infectious complication, duration of hospital stay and treatment cost were observed. Results: The weight loss in EEN group were less than those of TPN group(P<0.05). The levels of ALT, AST, BIL and GGT in EEN group on the eighth day after operation was lower than those in TPN group(P<0.05). The anal exsufflation time and duration of hospital stay in EEN group were shorter than those of TPN group(P<0.05). The treatment cost of EEN group was significantly less than that of TPN group(P<0.05). The infectious complication rate of EEN group was lower than that of TPN group(P<0.05). Conclusion: EEN in postoperative elder patients with esophageal and cardiac cancer can decrease the postoperative infectious complication and the treatment cost, shorten the duration of hospital stay, improve nutritional status and recovery of gastrointestinal function with less side effects of liver function.

The conventional therapy for arteriosclerosis obliterans (ASO) is Western medicine. However, it has some adverse effects and does not respond to some patients, and it is also very expensive.
