BACKGROUND:Many domestic and foreign scholars and institutions are studying how to relieve radiation damage and to find the most suitable drug, while ginsenosides as the main pharmacological ingredient of ginseng show significant antioxidant effect. OBJECTIVE:To investigate the ease effect of ginsenosides on human hematopoietic stem cels under different intensities of ionizing radiations. METHODS: The CD34+ hematopoietic stem cels were isolated from the healthy cord blood. Then the cels were divided into normal group and ginsenoside-pretreated group, respectively, exposed under 1, 2, 5 Gy of X-ray irradiations for 24 hours. Cel viability was detected in irradiated hematopoietic stem cels by MTT assay. Apoptosis was estimated using the folowing assays: Annexin-V assay, caspase-3 mRNA and protein levels. The generation of reactive oxygen species was evaluated, in the presence or absence of ginsenoside in liquid cultures of CD34+ human hematopoietic stem cels irradiated with 1-, 2- and 5-Gy X-rays, using a flow cytometry assay. The Nrf-2 mRNA and protein levels were also studied by western blot analysis and RT-PCR, respectively. RESULTS AND CONCLUSION: Ionizing radiation at the therapeutic dose could decrease the viability of CD34+ cels and induce the cel apoptosis, and meanwhile, the activity of intracelular reactive oxygen species also showed a progressive increase that was correlated with the dose of ionizing radiation. However, ginsenoside pretreatment could relieve these above-mentioned effects. Ginsenoside inhibited the increase in caspase-3 activity induced by ionizing radiation, and additionaly, enhanced the mRNA and protein expressions of Nrf-2 in CD34+cels. In conclusion, ginsenoside protects CD34+ hematopoietic stem cels from radiation effects, which is probably correlated with anti-apoptosis and anti-oxidant roles of ginsenosides.

Objective To evaluate of value of HER2 as a prognostic marker,and to analysis associations with common his-topathological parameters in BC cases.Methods In this study,formalin-fixed,paraffin-embedded samples of tumors from 160 breast cancer patients who underwent curative surgery proce-dures between 2011 and 2014 were tested by immunohisto-chemistry (IHC)as aprimary estimate of HER2 status,followed by fluorescence in situ hybridization (FISH).Concordance rate between IHC and FISH was evaluated.Theχ2 test was used to evaluate the correlation between HER2 gene amplifica-tion status and different clinical pathological features including:(estrogen receptor)ER and (progesterone receptor)PR ex-pression,age,menopausal status and tumor size.Results There was a significant inverse association between expression of hormone receptors (ER and PR)and HER2 amplification (all P<0.05)among the patients studied.However,no relation-ship was observed between HER2 amplification and age,menopausal status and tumor size (P>0.05).HER2-negative le-sions were of higher grade and more likely to be ER-negative,PR-negative,p5 3-positive,lymph node metastasis,and also Ki-67≥20% as compared to the HER2-positive group and HER2 overe xpression was associated with the levels of ER and PR. Conclusion There is correlation of many clinical factors with HER2 expression.

Objective To explore the application and effects of bone lengthening growth diary in self management of patients after lower limb lengthening. Methods A total of 54 cases applying lower limb lengthening were divided into the experimental group (n=28) and the control group (n=26) with random digit table. The basic treatment was consistent, the control group was given routine guidance, the experi-mental group implemented self- management with bone lengthening growth diary. Self- recognition of disease was assessed and compared between the two groups 12 weeks after operation. Self- efficacy and self- manage ment were assessed and compared between the two groups 2 and 12 weeks after operation. Results The self- recognition of disease in the observation group was better than that of the control group, for patients with higher self- recognition degree (21 cases vs. 10 cases), χ2=8.64, P<0.05, the difference was significantly different. The total scores of self- efficacy and self- management in the observation group were higher than those of the control group,(48. 42±3.43) vs.(34.14±4.13),t=11.750, P<0.01;(55.35±2.69) vs.(42.15±3.67), t=15.130, P<0.01, the difference was significantly different. Conclusions Bone lengthening growth diary plays a beneficial role on self-management of patients with lower limb lengthening.

Objective To investigate the effect of mild hypothermia on expression of autophagyrelated proteins LC3 and Beclin-1 in the hippocampus of rats with traumatic brain injury (TBI).Methods Sixty healthy male adult SD rats were divided into sham group, TBI group, hypothermiatreated group (31-33℃) according to the random number, with 20 rats per group.Rat models of TBI were established using the Marmarou's method.After 4 h of normothermia or hypothermia, the rats were killed 6, 12, 24, and 48 h later.Co-localization of LC3 with neuron specific protein (NeuN) or mammalian target of rapamycinm (mTOR) was determined by double immunofluorescence.Levels of LC3, Beclin-1 and p-mTOR proteins were detected by Western blot analysis.Results LC3 co-localization with NeuN (or mTOR) was observed under confocal laser scanning microscope.In TBI group LC3 and Beclin-1 levels were seen to rise at 6 h, peaked at 24 h and fell slightly at 48 h, but the levels were still higher than these in sham group (P ＜ 0.05).In TBI group p-mTOR level began to decrease at 6 h, reached the lowest point at 12 h, and then ascended at 24 and 48 h, but the level was still lower than that in sham group (P ＜0.05).Mild hypothermia contributed to remarkable decreases in LC3 and Beclin-I expressions, while up-regulating p-mTOR after injury (P ＜ 0.05).Conclusion Mild hypothermia appears to be neuroprotective as it inhibits autophagy in hippocampal neurons after TBI in rats through activation of mTOR signaling pathway.

Objective: To estimate the early physical growth and disease in children born to HBsAg-positive mothers. Methods: This was a retrospective cohort study. Three areas as Xihu in Hangzhou, Lanxi in Jinhua, and Haiyan in Jiaxing in Zhejiang province were selected by cluster sampling. The growth outcomes of children born to HBsAg-positive mothers (exposure group) and matched 1∶1 women uninfected with HBV (control group) in 2014 were investigated and compared at birth, 6, 9, 12, and 18 months, respectively. There were totally 342 children in each group. Results: The incidences of low birth weight (LBW) for children born to exposure and control group were 1.8% (6/342), and 2.6% (9/342), respectively (P=0.433); and, rates of preterm birth were 2.3% (8/342), and 2.0% (7/342), respectively (P=0.794). The mean birth weight of children born to mothers without HBV infection (3.4±0.4) kg was dramatically higher than children in exposure group (3.3±0.4) kg (P=0.019). At 18 months, the average head circumference was significantly greater among children in control group (47.3±1.3) cm than children in exposure group (47.0±2.0) cm (P=0.038). Additional, mean birth weeks, height, weight, increases in height/weight/head circumference each month, weight/height/head circumference for age Z scores, proportion of growth retardation and low weight, disease prevalence were not observed statistically differences between two groups (P>0.05). All children born to HBsAg-positive mothers were received three-dose HBV vaccination. The rate of hepatitis B immunoglobulin for births born to HBsAg-positive was 98.8% (338/342). Mother to children transmission of HBV at 18 months was 1.0% (1/97). Conclusion No significant differences in growth development and disease prevalence were found among children born to HBsAg-positive women and women without HBV infection.

BACKGROUND/AIMS: Early adverse life events (EALs) are relevant to irritable bowel syndrome in adulthood. Maternal separation (MS), as one of the EALs, has proved to induce visceral hypersensitivity in adult rats. However, the effect of MS on visceral hypersensitvity from the post-weaning period to adulthood remains unknown. METHODS: One hundred and ten neonatal Sprague-Dawley rats were randomly divided into 2 groups: rats in the MS group were exposed to 3 hours daily MS on postnatal day (PND) 2–14; the normal control (NC) group remained undisturbed. Visceral sensitivity was determined by measuring the visceromotor response to colorectal distention on PND21, 35, and 56. Anxiety-like behaviors were measured by the open field test. RESULTS: Compared with NC rats, MS rats showed significant visceral hypersensitivity from the post-weaning period to adult. The proportion of visceral hypersensitive rats decreased with age from 87.5% to 70.0% in the female MS group and from 90.0% to 66.7% in the male MS group. The relative VMR ratio of MS and NC on PND21 was higher than PND35 and PND56. MS rats showed decreased ability of movement and exploration to the novel environment in the post-weaning period, obesity in the prepubertal period, and more anxiety-like behaviors in adulthood. CONCLUSIONS: MS can significantly affect visceral sensitivity and behaviors of rats in different age stages, especially in the post-weaning period. Visceral hypersensitivity of MS rats is more pronounced in the post-weaning period and slightly restored in adults. Thus, visceral hypersensitivity in the post-weaning period might play a more meaningful pathophysiologic role in the formation of adult irritable bowel syndrome.

Objective:To explore the effect of transcutaneous electrical nerve stimulation (TENS) on interleukin-33 (IL-33)/growth stimulation expressed gene 2 (ST2) signaling pathway in the dorsal root ganglia (DRGs) of rats modeling hyperalgesia (HP).Methods:This study consisted of two experiments. In the first, 30 Sprague-Dawley (SD) rats were randomly divided into a blank group, a Sham-HP group, an HP group, an antibody group and an inhibitor group, each of 6. HP was induced in all except the rats of the blank and Sham-HP groups by injecting carrageenan (Car) and prostaglandin E2 subcutaneously at the bottom of the left hind feet. The antibody and inhibitor groups were then given intrathecal injections of anti-ST2 antibody and a tumor necrosis factor α (TNF-α)-specific inhibitor, respectively. In the second experiment, 42 SD rats were randomly divided into a Sham-HP group, an HP group, a TENSⅠgroup, a TENS II group, a TENS I inhibitor group, a TENS II inhibitor group, and a Sham-TENS group, each of 6. All of the groups had HP induced as in experiment one. All of the rats except those in the Sham-HP, HP and Sham-TENS groups were then given TENS, and the TENS I and II inhibitor groups were offered intrathecal injection of TNF-α-specific inhibitors. Mechanical pain thresholds (MPTs) were documented 4h, 24h, 48h, 72h, 6d, 7d 4h, 7d 1h, and 7d after the Car injections. Western blotting was used to measure the protein expressions of IL-33, ST2 and TNF-α 6d after the Car injection in both experiments.Results:In experiment one, the average MPTs of the HP, antibody and inhibitor groups had decreased significantly 4 hours after the Car injection compared with the blank and Sham-HP groups. However, 7d 1h after the Car injection the value had increased significantly in the Sham-HP, antibody and inhibitor groups compared with the HP group, while the expressions of IL-33, ST2 and TNF-α had decreased significantly. In experiment two, by 4 hours after the Car injection, the average MPT of all the other groups had decreased significantly compared with the Sham-HP group. Moreover, by 7d 1h after the Car injection, the average MPTs of the groups receiving TENS had increased significantly, with significantly lower MPT in the TENS Ⅱ group than in group Ⅰ, on average. There was also significantly higher expression of IL-33, ST2 and TNF-α in group II. Compared with the TENS Ⅰ and Ⅱ groups, the average MPT was significantly higher in the TENS I and Ⅱ inhibitor groups, but IL-33, ST2 and TNF-α expression was lower.Conclusions:TENS can inhibit TNF-α expression, which influences the signals of the DRG IL-33/ST2 signaling pathway to reverse hyperalgesia. TENS combined with anti-TNF-α treatment is superior to TENS alone in treating hyperalgesia.

Objective To investigate the accuracy of body mass index (BMI) as the evaluation standard for obesity in Miao adults in Guangxi, to find out the BMI cutoff value suitable for the evaluation standard of adult obesity, and to provide an accurate and reliable reference value for the prevention and treatment of obesity in Miao nationality adults. Methods Using a cross-sectional design, residents aged 18 years or older in the Miao villages in Rongshui Miao Autonomous County, Guangxi, were selected as the research subjects, and their body composition was measured. The percent body fat (PBF) standard was used as the ^“gold standard^” for obesity, and the BMI standard for obesity in Chinese adults was used as the positive screening standard. The accuracy of the BMI standard was evaluated, and the ROC curve analysis was used to determine the optimal BMI cutoff value for obesity in Miao adults. Results The detection rate of obesity of Miao adults in Guangxi by BMI method was lower than that by PBF method (10.3% vs 19.0%, χ²=426.62, P<0.001). The results of reliability evaluation showed that BMI was in good agreement with PBF in judging obesity (Kappa=0.59, P<0.001). BMI as a screening criterion for obesity in Miao adults showed high specificity and low sensitivity, low Yordon index, high positive predictive value and high positive likelihood ratio, and low negative predictive value and high negative likelihood ratio. When the PBF was used as the ^“gold standard^”, BMI had a good diagnostic performance for obesity in Miao adults (AUC=0.959, P<0.001). The optimal BMI cutoff points for obesity in adults of Miao nationality in Guangxi were 25.85 kg/m² and 25.55 kg/m² for men and women, respectively. Conclusion BMI is of great value for the diagnosis of obesity in Miao adults, but it should not be used as an exclusion criterion for obesity. Especially in the case of a small sample size, the risk of misclassification bias is relatively high.
