The nutritional value of rice germ additive was evaluated by biological method. The experiment was divided into four groups: in the first and second groups the rats were fed with 10% and 20% rice germ additive, the third group as a positive control received 1.1% casein additive, and the fourth was rice germ free group. The main nutrients such as protein, fat and carbohydrate contents in the first three groups were basically equal.The experimental results showed that the growth curve and other criteria of the rice germ additive were as same as the 1.1% casein additive group but 10% rice germ group was slightly better than the 20% group, especially the weights of males were increased more rapidly than the females.At the end of the experiment, no significant differences were found among the four tested groups in hemoglobin contents, weights of cerbrum, spleen and thymus. The data indicated that the nutritional effect of 10% rice germ additive was comparable to 1.1% casein additive. So the rice germ may be acceptable as a new potential source of protein, vitamin and mineral for human and animal foods.

ObjectiveTo compare the therapeutic efficacy between warm needling and Western medication in treating chronic atrophic gastritis.MethodSixty patients were randomized into an observation group and a control group, 30 cases in each group. The observation group was intervened by warm needling, selecting Guanyuan (CV4), Qihai (CV6), Zusanli (ST36), Xuehai (SP10), and Geshu (BL17); The control group was by Western medication, including Omeprazole, Amoxillin, Metronidazole, etc. The clinical efficacies were compared after 8-week treatment. Besides, gastroscopewas ordered at outset and after 8-week treatment to compare the therapeutic efficacies.ResultIn comparing the clinical symptoms, the total effective rate was 93.3% in the observation group versus 70.0% in the control group (P<0.05); the gastroscope scores dropped significantly in both groups after 8-week treatment (P<0.05), and the score of the observation group was significantly lower than that of the control group (P<0.05). ConclusionAcupuncture-moxibustion can significantly improve the clinical symptoms and gastroscopic results in patients with chronic gastritis, and its therapeutic efficacy is superior to that of Western medication.

Objective To investigate the imaging features of adrenal rest tumor.Methods Twelve patients of adrenal rest tumor proved by surgery or clinical diagnosis were retrospectively analyzed.Among these 12 patients,12 were examined with ultrasound,11 with MR and 1 with CT. MR and CT were performed without and with intravenous injection of contrast material.The imaging features of adrenal rest tumor were retrospectively summarized and the relevant literatures reviewed. Results The adrenal rest tumors were found in testis in 10 of the 12 patients,and in ovaries and broad ligament in the remaining two.The imaging features of the testicular adrenal rest tumor were summarized as following:all patients had bilateral testicular masses without change of the testicular contour. On ultrasonography,the lesions were hypoechoic, with some hyperechoic areas and appeared highly vascularized on Colour Doppler ultrasonography.The masses showed iso-density on plain CT,and avid enhancement on post-contrast CT images.The masses ranging in size from0.7 cm×1.0 cm×2.2 cm to 2.3 cm ×2.7 cm ×2.9 cm with uniform signal intensity,lobulated margin on MRI.They exhibited iso- or slight hyperintensity on T1 WI and hypointensity on T2WI relative to normal testicular parenchyma.The tumors showed intense enhancement on post-contrast MR images. No abnormality was detected with Colour Doppler uhrasonography and MR in 2 patients of adrenal rest tumor in ovaries and broad ligament. Conclusion Combining imaging features with the typical clinical history,the diagnosis of adrenal rest tumor could be suggested pre-operatively.

BACKGROUND:During the process of acute brain injury after stroke, matrix metaloproteinase can undermine the integrity of vascular basement membrane, promote the migration of neutrophils and inflammatory factors, and cause secondary brain injury. OBJECTIVE:To investigate the activation of matrix metaloproteinase 2/9 and the degradation rule of claudin in rat models of middle cerebral artery ischemia at different ischemic durations. METHODS:Thirty-nine male SD rats were randomly divided into three groups according to different ischemic durations (3, 5 and 7 hours) . Middle cerebral artery occlusion (stroke) model was established using modified suture method,i.e., separation of the external carotid artery, inserting the suture into the internal carotid artery through the external carotid artery, and eventualy reaching the middle cerebral artery. The ischemic duration in these three groups was respectively 3 , 5 and 7 hours. After 2 hours of reperfusion, Zea-Longa score and Ludmila Belayev score, brain infarct area, matrix metaloproteinase 2/9 activities and claudin 5 degradation were determined in each group. RESULTS AND CONCLUSION:With the extension of ischemic duration, brain infarct area gradualy increased, central nervous system damage gradualy aggravated, matrix metaloproteinase 2/9 activities gradualy increased, and claudin-5 expression gradualy decreased. There were significant differences between any two ischemic durations in terms of each of above-mentioned indices. The results indicate that after long duration of ischemia, the progressive damage of brain tissue can cause the gradual increase of activation of matrix metaloproteinase 2/9 and the gradual degradation of claudin 5.

Objective To study the association between three single nucleotide polymorphisms (SNP; rs2241766,rs1501299 and rs12495941) variants of the adiponectin gene (ADIPOQ) and polycystic ovary syndrome (PCOS) in PCOS family trios.Methods A total of 224 unrelated PCOS probands,their biological parents were recruited.Anthropometric variables such as waist circumference (WC),hip circumference (HC),height and weight were measured in all subjects during the first visit to the outpatient department.Body mass index (BMI) and waist-hip ratio (WHR) were calculated.Serum fasting glucose (FBG),fasting insulin (FINS),total cholesterol (TC),triglycerides (TG),low-density lipoprotein and highdensity lipoprotein cholesterol (HDL) levels were measured.PCOS patients were divided into two groups based on BMh group A (BMI＜25 kg/m2) and group B (BMI≥25 kg/m2).Parents of PCOS patients were accordingly categorized into group C,D (fathers) and group E,F (mothers).The transmission disequilibrium test (TDT) was used to analyze the association between three SNP of ADIPOQ and PCOS.Results (1) A significant positive association was detected between SNP rs1501299 and PCOS (x2=7.093,P=0.008).However we failed to find significant overtransmission of the other two SNP rs2241766 and rs12495941 from parents to PCOS offsprings (x2=1.620,P=0.203; x2=0.713,P=0.398).(2) Linkage disequilibrium (LD) was analyzed in the subjects,rs1501299 and rs2241766 were in weak LD (r2=0.063,D'=0.621).(3) The levels of WC,HC,WHR,testosterone,TG,HDL and FINS were significantly differences between obese and lean PCOS patients (P＜0.05).While in fathers we only found WC,HC,TC levels being statistically different (P＜ 0.05).Mothers of obese PCOS patients had increased levels of FINS compared with mothers of lean PCOS patients (P＜0.05).The genotype frequencies of the three SNP were not different in obese and lean PCOS patients and their parents (P＞0.05).Conclusions TDT confirms that SNP rs1501299 in the ADIPOQ is significantly associated with the risk of PCOS in the Chinese Han population.The three SNP of the ADIPOQ were not associated with the obesity of PCOS.

AIM: To investigate the expression and effects of sialyl Lewis X (SLeX) on the invasion and migration of human hepatocellular carcinoma HepG2 cells.METHODS: The expression of α1,3-fucosyltransferase VII (FUT7) in HepG2 cells and L-02 cells was detected by RT-qPCR and Western blot.The SLeX expression in HepG2 cells and L-02 cells was determined by Western blot and immunocytochemical staining.The invasion and migration abilities of the treated cells were evaluated by Transwell assay.RESULTS: The expression of FUT7 and SLeX in the HepG2 cells, but not in the L-02 cells, was observed.The invasion rates of the HepG2 cells treated with SLeX monoclonal antibody at 0.05, 0.5 and 5 mg/L were significantly decreased as compared with control group (P<0.05).The migration ability of the HepG2 cells treated with SLeX monoclonal antibody at 0.05, 0.5 and 5 mg/L was also significantly reduced as compared with control group (P<0.05).The invasion rate and migratory cell number were significantly different between any 2 groups in the HepG2 cells treated with SLeX monoclonal antibody at 0.05, 0.5 and 5 mg/L (P<0.05).CONCLUSION: HepG2 cells express SLeX.SLeX is closely related to the migration and invasion abilities of the HepG2 cells.

Objective To investigate the expression and clinical significance of T-cell receptor (TCR) Ⅴβ subfamily in hepatitis B virus (HBV)-related acute-on-chronic liver failure (HBV-ACLF) patients.Methods Twenty-eight patients with HBV-ACLF (HBV-ACLF group) and 32 patients with chronic hepatitis B flare (CHB-F group),who were treated in The Second People's Hospital from Oct.2010 to Mar.2012,and 20 healthy controls (HC group) were included in the study.Reverse transcriptase-polymerase chain reaction was used to detect the levels of TCR Ⅴβ subfamily and enzymelinked immunosorbent assay was used to detect the levels of serum cytokines [interleukin (IL)-2,IL-4,IL-6,IL-10,interferon (IFN)-γ and tumor necrosis factor (TNF)-α)] in the three groups.The comparison among three groups was done by one-way analysis of variance and the comparison between two groups was done by LSD-t test or rank sum test.Results The three groups had similar gender and age distribution (all P＞0.05).The HBV-ACLF group had significant different profiles of total bilirubin,albumin,prothrombin activity,international normalized ratio and cholesterol tatol compared with the CHB-F group (all P＜0.05).For patients in the HBV-ACLF group,the serum IL-2,IL-4,and IL-10 levels were lower(all P=0.000),and the IL-6 and IFN γ levels were higher than those of the HC group (all P=0.000).The IL-4,IL-10,and TNF-α levels in the CHB-F group were also significantly lower than those of the HC group (all P=0.000).Compared with the CHB-F group,the HBV-ACLF group had significantly lower IL-2,IL-10,and TNF-α levels (P=0.003,0.002,0.004),and higher IL-6 and IFN-γ levels (P=0.015,0.006).By one-way analysis of variance,there were significantly differences of △Ct1,△Ct5,△Ct7,△Ct12,△Ct15,△Ct20,△Ct22,and △Ct23 among the three groups (H=20.368,14.368,19.500,31.532,19.985,19.116,41.752 and 20.649,all P＜0.05).Conclusion The expression levels of TCR Ⅴβ subfamily and cytokines are changed in HBV-ACLF patients.
