1.Process of neovascularization in mediating regulation of parathyroid hormone on metabolism of target organs
Chinese Journal of Endocrinology and Metabolism 2017;33(4):351-354
Neovascularization plays an essential role in the process of renovation in tissue damage,tumor growth, and hormones action. Parathyroid hormone (PTH) is one of the basic hormones that regulate the serum calcium, phosphorus, and bone metabolism. In recent years, studies involving the neovascularization-mediated effects of PTH on metabolism are becoming more and more popular and wider. Based on recent researches, the purpose of this paper is to summarize the changes of angiogenesis while PTH interacts with its target organs, especially interacts with osseous tissue.

Purpose To investigate the expression of insulin-like growth factorIImRNA binding protein 3 ( IMP3 ) and microvessel density (MVD) in squamous carcinoma of the cervix (SCC) and analysis their relationship in SCC. Methods The expression of IMP3 and MVD was examined by immunohistochemistry SP method in normal cervical epithelium ( NCE) , low-grade cervical intraepi-thelial neoplasia (CIN-L), high-grade cervical intraepithelial neoplasia (CIN-H) and SCC. Results (1)The positive expression rates of IMP3 in NCE, CIN-L, CIN-H, SCC tissues were 0(0/15), 0(0/11), 37.5%(9/24) and 86.0%(43/50), the difference was statistically significant (x 2 =53.345, P=0.000). IMP3 expression was significant difference among NCE and CIN-H, SCC (P<0.008 3), and that was also among SCC and CIN-L, CIN-H (P<0.008 3). (2)The MVD count was increased with the development of cervical squamous lesion, there was significant difference among those groups (F=145.968, P<0.01), and the difference was al-so statistically significant between every two groups (P<0.05). The positive expression of IMP3 and MVD count in 50 cases of SCC tissues showed statistical difference in different pathologic grade, lymph node metastasis, and depth of tumor invasion groups ( P<0.05), but didn't in different patients’age groups (P>0.05). And the positive expression of IMP3 was closely related with MVD count in SCC tissues (rs =0.323, P<0.05). Conclusion IMP3 plays an important role in the occurrence, infiltration and metasta-sis of SCC, and the abnormal expression of IMP3 may relate with the angiogenesis of tumors.

In this article we report the results on the synthesis and accumulation of PHAs by Rhodocista pekingensis (strain 3-p), a phototroph that was isolated from wastewater treatment plant. Our results showed that the optimal conditions for PHAs accumulation with strain 3-p were as following: 0.01% Yeast Extract, 0.01% NH 4Cl, Acetate 5 g/L, and medium pH of 7.0~7.2.Under optimized conditions, strain 3-p accumulated PHAs up to 60% of its cellular dry weight. Enzymatic activities of ?-ketothiolase, acetoacetyl-CoA reductase, and PHA polymerase were detected and their activities increased as PHA synthesis initialized. Based on these study, we proposed the metabolic pathway of this strain should be:Acetate (or other fatty acids) - Acetyl-CoA --- thiolase Acetoacetyl-CoA --- reductase D (-)-?-Hydroxybutyryl-CoA ----- PHA polymerase PHAs.

Objective To study the effects of ethanol extract of rhizoma phragmitis on liver glycogen content and glycogen synthetase (GS) in streptozotocin (STZ) induced diabetic mice. Methods The diabetic model mice were divided in-to model control group, high-dose group and low-dose group, 10 mice for each group. Another 10 normal mice were used as control group. The liver glycogen content was detected by histochemical staining of glycogen (PAS) method. The expression of GS mRNA was detected by reverse transcription polymerase chain reaction (RT-PCR) and Western blot assays. Results After PAS staining the hepatic glycogen content decreased significantly in model control group, and which was significantly increased in low-dose group and high-dose group compared with that of model control group (P<0.01). The hepatic glyco-gen content was the highest in high-dose group compared with that of other three groups. The levels of GS mRNA and GS protein were significantly lower in model control group than those of other three groups, which were significantly lower in low-dose group than those of high-dose group (P<0.05). Conclusion There is a dose-dependent effect of ethanol extract of rhizoma phragmitis on liver glycogen in STZ induced diabetic mice, which may be related with the increased expression of liver glycogen synthetase.

AIM: To investigate the surgical methods of Helveston syndrome.
METHODS: Fifteen cases ( 30 eyes ) with Helveston syndrome were studied. Surgical method was selected according to the degree of superior oblique muscle overaction and dissociated vertical deviation (DVD).
RESULTS: Binocular superior oblique intrathecal tenectomy was performed in 8 patients (16 eyes). Follow-up period after surgery was 1-3a. Those 8 patients got A-sign correction, of which 3 patients (6 eyes) got DVD vanished and 5 patients (10 eyes) got DVD alleviation. None of the 8 cases needed another operation for DVD. Binocular superior rectus recession and binocular lateral rectus recession with vertical offsets was performed in 4 patients (8 eyes). Follow-up period after surgery was 1-3a. The 4 patients got A sign correction and with orthophoria, of which 1 patient ( 2 eyes ) got DVD vanished and 3 patients ( 6 eyes) got DVD alleviation. None of the 4 cases needed another operation for DVD. Binocular lateral rectus recession and vertical offsets was performed in 3 patients (6 eyes). Follow-up period after surgery was half a year, with orthophoria, no A sign, DVD weakened, and no second operation was needed. CONCLUSION: Surgical procedures for Helveston syndrome can be selected according to the degree of superior oblique muscle overaction and DVD.

Objective To investigate the association between the Adiponectin rs266729 and rs2241766 gene polymorphisms and nonalcoholic fatty liver disease in the Han Chinese population residing in Qingdao. Methods Adiponectin rs266729 and rs2241766 gene polymorphisms were genotyped in patients with NAFLD (n = 336) and healthy controls (n = 280) using polymerase chain reaction (PCR). Serum lipid profiles and adiponectin levels were determined using biochemical methods. Statistical analyses were performed using Pearson Chi square test, logistic regression analysis, t test, linear regression analysis. Results We found a significant association between the Adiponectin rs266729 genotype frequencies and allele frequencies between NAFLD pa-tients and controls (χ2= 9.929, P = 0.007; χ2= 9.809, P = 0.002). After adjustment of confounding factor, the rs266729 G allele was associated with an increased risk of NAFLD compared to the C allele (OR = 1.410, 95%CI: 1.082-1.831, P = 0.008) No significant differences were found in the rs2241766 genotype frequencies and allele frequencies between NAFLD population and the controls (OR = 1.410, 95%CI: 1.082-1.831, P = 0.008). Conclusion The Han Chinese in Qingdao carrying the rs266729 G allele are at increased risk of NAFLD.
