Glycogen storage disease (GSD) is a rela-tively rare inherited metabolic disease. However, its relative rarity implies that no metabolic centre has experience of large numbers of patients and experience with long-term manage-ment is limited. In addition, there is wide variation in meth-ods of medical treatment. With the development of medical care, life-expectancy in glycogen storage disease (GSD) has improved considerably. With ageing liver adenoma may de-velop which will bring about several complications-compres-sion, hemorrhage, or even transformation into carcinomas-and needs immediate intervention. In this paper, reviews for the mechanism and surgical intervention of GSD are presented.

BACKGROUND:RADA16 is a mature amphiphilic self-assembling peptide, which can be assembled into nanofibers, and promote MC3T3 E1 cellattachment, spreading and proliferation.
OBJECTIVE:To observe the effects of the new-type self-assembling peptide hydrogel NBD/RADA16 on osteogenic differentiation of mouse preosteoblasts MC3T3 E1.
METHODS:The MC3T3 E1 cells were inoculated in NBD/RADA16 self-assembling peptide hydrogel and RADA16 hydrogel for osteogenic induction. cells undergoing simple osteogenic induction served as controls. After culture for 1, 3, 6 days, the activity of alkaline phosphatase was detected. After 7 days, western blot assay was used to determine the expression of bone morphogenetic protein-2. After 21 days, alizarin red staining was used to observe calcified nodules.
RESULTS AND CONCLUSION:MC3T3 E1 cells grew wel on the NBD/RADA16 peptide hydrogel, which were superior to those on the RADA16 hydrogel. The activity of alkaline phoshpatase was higher in the NBD/RADA16 group than the RADA16 and control groups (P<0.01). Compared with the RADA16 hydrogel, mineralized matrix deposition and expression of bone morphogenetic protein-2 were higher on the NBD/RADA16 peptide hydrogel (P<0.01). These findings indicate that the NBD/RADA16 peptide hydrogel is superior to the RADA16 hydrogel for promoting the osteogenic differentiation of MC3T3 E1 cells.

Objective To investigate the prediction value of ultrasound endometrial pattern at the day of hCG administration on clinical outcome in patients undergoing in vitro fertilization-embryo transfer (IVF-ET).Methods 679 cycles of IVF-ET conducted between January 2011 and December 2012 in Beijing Obstetrics and Gynecology Hospital were reviewed retrospectively.All cycles were divided into three groups based on the endometrial pattern measured on the hCG day:group A (n =411) with triple line endometrium,group B (n =228) with no obvious triple line endometrium,group C (n =40) with homogeneous hyperechoic endometrium.Clinical outcomes such as implantation rate,pregnancy rate and miscarriage rate were analyzed.Results Among three groups,the implantation rates were 27.05％,20.33％,19.57％,respectively (x2 =9.04,P =0.01); the pregnancy rates were 34.31％,25.00％,12.50％,respectively (x2 =12.20,P =0.00).The implantation rate and pregnancy rate in group A were higher than the other two groups (P ＜0.05).The miscarriage rates were 16.31％,19.30％,40.00％,respectively(P ＞ 0.05),there were no significant difference among them.Conclusions The ultrasound endometrium pattern on the day of hCG administration has predictive value on clinical outcome in patients undergoing in vitro fertilization-embryo transfer.

[Objective] To explore how to deal with the paternity test of complex adoption cases. [Method] Samples from 13 families, in which adoptive parents were suspected related to biological parents, were genotyped using "Identifder + Sinofder + Powerplex 16" combined system (D8S1179, D21S11, D7S820, CSFIPO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, VWA, TPOX, D18S51, D5S818, FGA, D6S1043, D12S391, PentaD, PentaE) followed by further statistical analysis. [Result] Among all 13 cases, 2 were completely accordance with the Mendel law, PI > 10 000. There found more than 3 inconsistent loci in 8 cases. And found 1～2 inconsistent loci in 3 cases, needed to test more STR loci until PI≥10 000. The half sibling index (HSI) was also calculated with ITO method. The adoptive parents of 2 cases were not excluded from a full sibling with biological parents. In addition, Y-STR loci were tested for 4 cases (father/son). Two adoptive fathers of them were not excluded from the paternal relationship with biological fathers. [Conclusion] The most (76.9%) of all (13) complex adoptive cases of paternity test could be drawn a definite conclusion with combined system of "Identifder + Sinefiler + Powerplexl6". Minority (23.1%) of them was not definite yet and needed testing more STIR loci. Meanwhile, we suggested adding Y-STR tests and providing HSI for reference.

Objective To investigate the molecular mechanisms of synergistic effects of BFA and CDDP on human lung cancer GLC-82 cells, and to test the levels of PERK-ATF4 pathway. Methods GLC-82 cells were incubated with 50 ng/mL of BFA or/and 2 μg/mL of CDDP for 24 or 48 hours. The levels of PERK, p-PERK and ATF4 in GLC-82 were analyzed by real-time PCRand/or Western Blot. Results The levels of PERK were lowest in CDDP group, but higher in BFA group (P < 0.05), the highest in group of BFA+CDDP (P < 0.05 or P < 0.01). The p-PERK level decreased in group of BFA+CDDP (P < 0.05 or P < 0.01). There was no significant change of ATF4 expression in CDDP group, but ATF4 expression increased slightly in BFA group, and increased further in group of BFA+CDDP (P < 0.05 or P < 0.01)which was also higher than that in BFA group or CDDP group (P < 0.05 or P < 0.01). Conclusions The upregulated levels of PERK and ATF4 by the combination of BFA and CDDP may be one of the mechanisms of synergistic anti-cancer effect of BFA and CDDP on GLC-82 cells.

Spontaneous intracerebral hemorrhage (ICH) has the highest rates of mortality and morbidity in stroke types.Experimental and clinical studies demonstrate that inflammatory reactions are early triggered by hematoma components,enhance the damage within the hemorrhagic brain,and influence the prognosis.Recent studied show that neutrophil to lymphocyte ratio (NLR),as an easily available biomarker to assess the systemic inflammatory status,has predictive roles in patients with ICH.This article reviews the predictive roles of NLR in patients with acute ICH.

Objective: To study the characteristics of attentional bias to emotional stimulus in medical workers of emergency department and explore the relationship between the emotional Stroop effect and mood states, thus providing a reference to the assessment and intervention of emergency medical workers’ mental health. Methods: Two kinds of emotional Stroop tasks with words and pictures and the Profile of Mood States (POMS) were administered to thirty-six medical workers of emergency department and thirty-six medical workers of other departments. Results: The reaction time to negative and positive words and pictures were all higher than the reaction time to neutral stimulus, thus showing the significant Stroop effect in medical workers. The Stroop effect to negative emotional stimulus in medical workers of emergency department was significantly smaller than that in medical workers of other departments, while the difference of Stroop effect to positive stimulus was not significant between the two groups. Correlation analyses revealed that the correlations between Stroop effect size to positive pictures and tension and angry of POMS were all negatively significant (r value was -0.314 and -0.330 respectively) , and the correlation between Stroop effect size to negative pictures and fatigue was negatively significant (r=-0.303) . Conclusions There is a significant emotional Stroop effect in medical workers. Although the ability of anti-interference to emotional stimulus in medical workers of emergency department was better than medical workers of the other departments, the long-term avoidance to negative emotional stimulus was still has a negative effect on the mood states of individuals.

The establishment of an economic operating mechanisms for hospitals is a key factor in advancing the growth of public hospitals in the modern age.At present,the due value of key factors such as medical resources and labor value of medical personnel in public hospitals in China has not been fully reflected,which not only restricts the overall operation efficiency of hospitals,but also makes it difficult to realize the marginal value of hospital operation and management.The economic operating mechanisms of public hospitals is in urgent need of reform.Large public hospitals in Henan Province has established an economic operating mechanisms of public hospitals based on intelli-gent finance,comprehensive budget management as the core,and cost control and performance management as the major tools to realize the interconnection of various systems and promote the high-quality development of hospi-tals with the three major supports of industry and finance integration,financial integration and financial integration.

Objective:To evaluate the effect of gastrogin on AMP-activated protein kinase (AMPK)/transient receptor potential anchor protein 1 (TRPA1) signaling pathway in rats with neuropathic pain.Methods:Thirty-six SPF-grade healthy male Sprague-Dawley rats, aged 6-8 weeks, weighing 200-230 g, were divided into 3 groups ( n=12 each) using a random number table method: sham operation+ normal saline group (SHAM group), neuropathic pain+ normal saline group (NP group), and neuropathic pain+ gastrogin group (GAS group). Neuropathic pain was induced by chronic constrictive injury to sciatic nerve under 2% isoflurane anaesthesia. The sciatic nerve was only exposed but not ligated in SHAM group. Gastrogin 100 mg/kg was intraperitoneally injected for 14 consecutive days after developing the model in GAS group, while the equal volume of normal saline was given instead in SHAM and NP groups. The mechanical paw withdrawal threshold (MWT) and thermal paw withdrawal latency (TWL) were measured at 1 day before developing the model (T 0) and 1, 3, 5, 7, 10 and 14 days after developing the model (T 1-6). The rats were anesthetized and sacrificed following the measurement of pain thresholds at T 4 and T 6. The lumbar segment (L 4-6) of the spinal cord was removed for determination of TRPA1 mRNA expression (by quantitative real-time polymerase chain reaction), expression of TRPA1, AMPK and p-AMPK (by Western blot), expression of TRPA1 (by immunofluorescence staining) and expression of tumor necrosis-alpha(TNF-α), interleukin-1beta(IL-1β) and c-fos (by immunohistochemistry). Results:Compared with SHAM group, MWT and TWL were significantly decreased at T 1-6, the expression of TRPA1 mRNA, TRPA1, TNF-α, IL-1β and c-fos was up-regulated, the expression of p-AMPK was down-regulated ( P<0.05), and no significant change was found in AMPK expression in NP group ( P>0.05). Compared with NP group, MWT at T 3-6 and TWL at T 2-6 were significantly increased, the expression of TRPA1 mRNA, TRPA1, TNF-α, IL-1β and c-fos was down-regulated, and p-AMPK expression was up-regulated ( P<0.05), and no significant change was found in AMPK expression in GAS group ( P>0.05). Conclusions:The mechanism by which gastrogin reduces neuropathic pain may be related to modulating the expression of the AMPK/TRPA1 signaling pathway in rats.
