Adult male Kunming mice were divided into normal control group,propylthiouracil(PTU) treated group and PTU+T_4 treated group.Neurogranin(Ng)protein expression in the hippocampus after 8 weeks was assayed by Western blotting and immunohistochemical method.Results showed that Ng protein was decreased in the hippocampus of male mice with adult-onset hypothyroidism,suggesting that decreased Ng,which is correctable by T_4,is involved in cognitive dysfunction in adult-onset hypothyroid male mice.

OBJECTIVETo investigate the possible mechanism of compound Chinese sour taste herbs (CS) in preventing and ameliorating diabetic macroangiopathy by analyzing the effects of CS on the deposition of advanced glycation end products (AGEs) and gene expression of receptor for advanced glycation end products (RAGE) in the aorta tissue of rats with type 2 diabetes mellitus (T2DM).

METHODSRat model of T2DM was established by peritoneal injection of streptozotocin (STZ) and high caloric diet feeding. Experimental SD rats were divided into the normal group, the model group, the aminoguanidine (AG) group, and the CS group. At the end of the 8th and 12th week, the fasting blood glucose (FBG) was measured by glucose oxidase method; content of AGEs and collagen in aorta detected by fluorescent method and gene expression of RAGE in aorta determined by Real-time PCR method.

RESULTSFBG, AGEs and collagen contents and RAGE expression in aorta of model rats were all higher than those in the normal control group (P <0.05), while all these indices were lower in the CS group than in the model group (P<0.05).

CONCLUSIONCS could realize the goal for preventing and ameliorating diabetic macroangiopathy by way of suppressing the production of AGEs and down-regulating the gene expression of RAGE in aorta of T2DM rats.

OBJECTIVETo establish a quantitative model for evaluating the degree of the TCM basic syndromes often encountered in patients with primary liver cancer (PLC).

METHODSMedical literatures concerning the clinical investigation and TCM syndrome of PLC were collected and analyzed adopting expert-composed symposium method, and the 100 millimeter scaling was applied in combining with scoring on degree of symptoms to establish a quantitative criterion for symptoms and signs degree classification in patients with PLC. Two models, i.e. the additive model and the additive-multiplicative model, were established by using comprehensive analytic hierarchy process (AHP) as the mathematical tool to estimate the weight of the criterion for evaluating basic syndromes in various layers by specialists. Then the two models were verified in clinical practice and the outcomes were compared with that fuzzy evaluated by specialists.

RESULTSVerification on 459 times/case of PLC showed that the coincidence rate between the outcomes derived from specialists with that from the additive model was 84.53 %, and with that from the additive-multificative model was 62.75 %, the difference between the two showed statistical significance (P<0.01).

CONCLUSIONSIt could be decided that the additive model is the principle model suitable for quantitative evaluation on the degree of TCM basic syndromes in patients with PLC.

The complex field cure instrument is a new medical instrument with which an experiment was carried out. Rats were continuously irradiated by the complex field for 90 days, with a day's total dose of 285.9 M.T.G. while other rats weren't irradiated for control group. The animals were respectively killed at 7d, 14d, 30d, 60d and 90d, and their blood samples were taken for cell and humoral immune analysis. The results show that values of lymphocyte transform rate, soluble receptor (SIL-2R), total hemolytic complement levels (CH50) and immunoglobulin (A.G.) after irradiation are more than those of the control group having proved that the instrument may improve immune function of rats.

This article studied the chemical constituents from the aerial part of Vitis thunbergii var. taiwaniana. The 60% ethanol extract was eluted with 95% ethanol though HP-20 macroporous adsorption resin column. 12 compounds, including (1) betulinic acid, (2)2, 2, 2'-bis (4-hydroxyphenyl) propane bis (2, 3-epoxypropyl) ether, (3) eriodictyol, (4) trans-ε-viniferin, (5) (+)-cis-ε-viniferin, (6) kobophenol A, (7) ampelopsin A, (8) nepalensinol B, (9) cis-miyabenol C, (10) cis-vitisin B, (11) cis-gnetin H and (12) (+)-hopeaphenol, were separated by using normal phase silica gel, ODS, Sephdadex LH-20 column chromatographies and semi-preparative or preparative HPLC. Compounds 2, 5, 6, 8, 9, 10, 11 were separated from the genus Vitis for the first time and compounds 3, 7, 12 were separated from Vitis thunbergii var. taiwaniana for the first time. At a concentration of 50 μmol · L(-1), compound 6, 7 and 11 showed strong cytotoxicity against MCF-7 cell lines with the inhibition rate of 66.58%, 57.16%, 52.84%, respectively.

2600 Anthers from T0 modified cry1 Ac-transgenic rice lines of Minghui 81, an elite restoring line of commercial CMS indica hybrid rice, were cultured on SK3 media. 83 green plantlets were recovered, 43 double haploid (DH) and 40 haploid among them. Results of PCR analyzes indicated that 55 plants of 83 were harbored the cry1Ac gene, and the ratio of cry1Ac-positive against cry1Ac-negative was 2:1 (55/28). 36 putative transgenic DH plants were further confirmed by Southern blot. ELISA detection showed that Cry1Ac level in different transgenic rice plants of the same cry1Ac-DH clone was almost equal and the highest one amount to 0.25% of the total soluble protein. Pest insect-resistant bioassay at field trials demonstrated that some of the homozygous cry1Ac-transgenic rice plants not only showed high-level resistance against striped stem borer (Chilo suppressalis) but also retained elite agronomy characters. These results demonstrated that rice anther culture has a great value in rice molecular breeding.

OBJECTIVETo investigate the efficacy of surgical management for pyloric stenosis induced by gastrointestinal chemical burn in children.

METHODSClinical data of 11 children with pyloric stenosis induced by gastrointestinal chemical burn were analyzed retrospectively. After the failure of medicine, intervention of low balloon expansion and stent placement, they underwent pylorectomy and gastroduodenostomy. The body weight, height, serum albumin, hemoglobin, transferrin were compared between 1 day before and 3 months after operation.

RESULTSThere were 10 males and 1 female with a mean age of 4.5 years old. The main cause of serious pyloric stenosis was the wrong intake of hydrochloric acid. Lesions involved the esophagus and stomach in the early stage, and 4 weeks later, the lesion mainly involved the pylorus, which resulted in scarring pyloric stenosis and complete pyloric obstruction. Pylorectomy and gastroduodenostomy was successfully performed. The mean operative time was (134±26) min. The estimated blood loss was (5±2) ml. The postoperative length of stay was (10±3) d. There were no surgical complications. During the follow-up of 3 months, all the patients resumed regular diet. The height, body weight, and intelligence appeared to be normal. They showed significant improvement in weight, serum albumin, globulin, hemoglobin, transferrin at 3 months after the surgery(P<0.05). Six months after surgery, the anastomosis was shown to be nornal in barium follow through exam with no signs of stricture of ulcer.

CONCLUSIONPylorectomy and gastroduodenostomy is an effective management for pyloric stenosis induced by gastrointestinal chemical burn in children, whose short-term efficacy is good.
