The present study was aimed to investigate the effect of electroacupuncture (EA) on learning-memory of rats with low estrogen-induced cognitive impairment and the possible mechanism. The rat model was established by ovariectomy, which resulted in low estrogen-induced cognitive impairment. EA was applied continuously for 3 months 2 weeks after ovariectomy. Morris water maze was used to test the ability of spatial learning and memory. Enzyme-linked immunosorbent assay (ELISA) and real-time quantitative RT-PCR were used to detect the concentration of serum estradiol (E2) and relative expression of choline acetyltransferase (ChAT) mRNA in hippocampus, respectively. The result showed that, compared with the sham group, the ovariectomy model group exhibited longer escape latency, reduced number of platform-crossing, lower concentration of serum E2, and decreased expression of ChAT mRNA in hippocampus. EA shortened the escape latency and increased the number of platform-crossing in the ovariectomy model group. Moreover, the concentration of serum E2 and the hippocampal expression of ChAT mRNA in the ovariectomy model group were significantly elevated by EA treatment. These results suggest EA is capable of improving learning and memory in ovariectomized rats, and the mechanism involves the up-regulation of the expression of ChAT mRNA in hippocampus induced by the increase of the serum concentration of estrogen.

Growth patterns of trichome and contaminative bacteria in Spirulina sp. liquid culture were observed, and it was found that the number of neutral and alkalophilic bacteria was always 105～106 times of that of Spirulina sp. trichome. It would be very difficult to get real pure Spirulina sp. strain by classical methods of dilution plate, capillary and single trichome selecting methods. A great deal of contaminative bacteria was washed out by two pretreatment processes. Low speed centrifugation was designed to wash the strains which usually deposit at bottom, and filtration method was designed to treat the strains usually floating at surface. Sandwich plate and dilution plate were designed for the purification of the mobile strains and non-mobile strains, respectively. A lot of strains were purified by the above processes and pure single trichome formed pure colonies on plates.

Human tissue kallikrein-binding protein (Kallistatin, KAL), a secretory protein that participates in the regulation of multiple signaling pathways by binding to the extracellular receptor, however, at present has not been reported about the intracellular activity, and whether it has the similar biological activity with extracellular activity. Here we constructed no signal peptide KAL (NSK) into the adeno-associated virus vector to explore the intracellular activity of KAL. Both the endothelial cell and lung cancer cells could express KAL, but not secreted after rAAV2-NSK transfection. The proliferation and migration of human umbilical vein endothelial cells (HUVECs) were inhibited, but the apoptosis rate was not affected. The proliferation rates, mobility and tubule formation of all the three tested lung cancer cells, such as NCI-H446, NCI-H460 and A549, were inhibited to different extents. This cellular study not only confirmed the intracellular activity, but also suggested it may serve as a kind of "balance factor" in multi-targeted controlling, which may provide a new train of thoughts to explain the regulatory contradiction in PI3K-Akt signaling pathways by KAL.

Aromatase is a key enzyme responsible for in vivo estrogen biosynthesis. Inhibition of the activity of the aromatase has become an alterative way for treatment of breast cancer. In this review, the structure and catalytic mechanism of the aromatase is briefly introduced followed by thorough review of the progress in the study of the steroidal and non-steroidal aromatase inhibitors. This review is focused on the natural compounds that exhibit the aromatase inhibition, which include flavonoids, xanthones, coumarins, and sesquiterpenes. The structure-activity relationship of these compounds is also discussed.

Objective To investigate the relationship between the promoter of IL-12B gene polymorphism and the susceptibility and clinical features of chronic gastritis and duodenal ulcer with or without Helicobacter pylori(Hp) infection in children and adolescent.Methods Mucosal biopsies were obtained from 132 children and adolescent (patient group),including 100 children with chronic gastritis and 32 children with duodenal ulcer,undergoing an upper gastrointestinal endoscopy for dyspeptic symptoms.Biopsy specimens were stained with hematoxilin and eosin (HE),and gastritis was graded according to the Sydney system.Serology,urease test and histology were taken to assess Hp status.Genomic DNA was obtained from peripheral blood or gastric biopsies of patients and 102 healthy children as normal control group.The promoter of IL-12B +1188A/G gene polymorphism was genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and sequencing.The genotype distributions and allele frequencies were compared between the study group and the normal control group,and the association of genotypes with clinicopathological features was studied.IL-12B mRNA level expressions in gastric mucosa were confirmed by reverse transcription PCR biopsy-based tests.Results The genotype distributions and allele frequencies of IL-12B +1188A/G gene polymorphisms were similar in gastric upper gastrointestinal diseases and healthy subjects.The IL-12B +1188A/G gene polymorphisms were not associated with Hp status.IL-12B+1188A/G gene polymorphisms did not affect IL-12B mRNA level expressions and were not associated with the degree of antrum chronic inflammation.Conclusions These data suggest that IL-12B+1188A/G gene polymorphisms are not associated with susceptibility to chronic gastritis and duodenal ulcer in children and adolescent.

Objective To investigate the diagnostic yield and accuracy of double balloon enteroscopy, barium enteroclysis and capsule endoscopy in patients with suspicion of small bowel tumors. Methods Double balloon enteroscopy were performed in fifty nine patients with suspicion of small bowel tumors.The route of enteroscopy could be either via mouth or via anus.At the same time,34 and 17 out of 59 subjects received either barium enteroclysis or capsule endoscopy.The results of exams were analyzed independently and final diagnosis of each case was compared thereafter.Results Nineteen of 34 patients undergone the enteroclysis were diagnosed as small bowel tumor.The diagnostic yield was 55.9%.The diagnosis was finally confirmed by the enteroscopy in 12 cases,which indicated the accurate rate of enteroclysis was 63.2%(12/19).Double balloon enteroscopy detected tumors in 3 of 15 subjects with negative enteroclysis finding.The diagnostic yield of capsule endosocpy was 47.1%(8/17),and among the 8 cases diagnosis was comfirmed by the enteroscopy in 4 cases.Small bowel tumors were detected in 2 of 9 cases with negative capsule endoscopy findings.Thirty-six cases of small bowel tumor were detected by double balloon enteroscopy via a route(mouth or anus),and 16 patients were diagnosed after both route procedure.No small bowel tumor was found in 7 paitents.The overall diagnostic yield of enteroscopy was 88.1%.The diagnosis were all finally confirmed by pathological examination.No procedure-related complication were observed.Conclusion Double balloon enteroscopy is superior to enteroclysis and capsule endoscopy in diagnostic yield and accuracy for small bowel tumors.

The dynamic changes of germination percentage, germination potential, thousand-seed weight, antioxidase activity in Desmodium styracifolium seeds with different storage time were tested, and electrical conductivity, contents of soluble sugar, soluble protein, starch in seed leach liquor were also determined in order to reveal the mechanism of seed deterioration. The results as the following. (1) The germination percentage, germination potential and thousand-seed weight of D. styracifolium seeds declined, while the seed coat color darkened with the extension of storage time. (2) The activities of superoxide dismutase (SOD) and peroxidase (POD) decreased with the prolongation of storage period. The SOD activity declined fastest in 1,095-1,185 d of storage, while the POD activity declined significantly in 365-395 d of storage. (3) The electrical conductivity and the contents of soluble sugar, starch in seed leach liquor increased, while the content of soluble protein declined with the extension of storage time. (4) Correlation analysis indicated that the germination percentage, germination potential and thousand-seed weight of D. styracifolium seeds have a significantly positive correlation with SOD and POD activity, while have a significantly negative correlation with the electrical conductivity, contents of soluble sugar and starch. It can be concluded that during the storage of D. styracifolium seeds, physiological and biochemical changes including decrease in antioxidase activity, rise in electrical conductivity, degradation effluent of soluble sugar and starch, degradation of soluble protein were the main factors leading to the seed deterioration.
