Objective To explore the relationship between platelet to lymphocyte ratio (PLR) and microangiopathyin type 2 diabetes mellitus. Methods In this case-control study, the clinical data on 428 adult patients with type 2 diabetic microangiopathy in our hospital from January 2009 to December 2015 were retrospectively analyzed. PLR, age, sex, fasting blood glucose, glycosylated hemoglobin, total cholesterol and triglyceride were tested to investigate their relationship with type 2 diabetic microangiopathy. Results Logistic regression analysis showed that PLR was a risk factor of type 2 diabetic microangiopathy (OR = 3.162, 95%CI:1.556 ~ 7.421, P < 0.05). Conclusions Greater PLR is closely related to type 2 diabetic microangiopathy, and we should pay attention to type 2 diabetic microangiopathy with a greater PLR in clinical practice.

[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 effects of icarrin on the activity and protein expression of core binding factor otl(Cbfa1) in rat osteoblasts cultured in vitro,and to explore whether mitogen-activated protein kinase (MAPK) pathway is involved in this process.Methods Calvarial osteoblasts were obtained from newborn (<24 h) SD rats by trypsin-coUagenase digestion method.The second generation osteoblasts were cultured in the medium containing icariin (10 ng/ml) or estradiol (10-8 mol/L) with or without extracellular-signal regulated kinase (ERK) inhibitor (UO126) or p38MAPK inhibitor (SB203580).Nuclear protein was extracted from osteoblasts.And then the activity of Cbfa1 was detected by ELISA.The amounts of Cbfa1 protein were detected by Western blot.Results Calvarial osteoblasts were obtained successfully and were used in this study after indentified by alkaline phosphatase and mineralized nodus staining.Cbfa1 expression and the activity in osteoblasts were up-regulated by both icariin and estradiol (P<0.05).The effects were partly inhibited by addition of U0126or SB203580 (P<0.05).Conclusions Either icarrin or estradiol can stimulate the proliferation and maturation of cultured osteoblasts in vitro via up-regulating the activity and expression of Cbfal.The MAPK signal pathway inhibitor seems to partly decrease Cbfa1 activity.It suggests that MAPK pathway may be involved in the transduction of icariin's impact on proliferation and mineralization of osteoblasts.

Objective To analyze the clinical features and gene mutation in mthylmalonic acidemia (MMA) accompanied by homocysteinemia (cblC), and review the relevant literatures. Methods The clinical features of 3 cases of MMA diagnosed by gene detection were retrospectively analyzed, and meanwhile the pertinent literatures of pathogenesis of MMA, especially combined with late-onset cblC and its gene detection, were reviewed. Results Patient 1 (26 days old) suffered from intermittent convulsions for 3 days, with isosuccinic acid 175.8 μmol/L, C3/C2 rate 1.363, homocysteine >?65 μmol/L and abnormal EEG. MMACHC gene detection found an exon deficiency (delEXON1), which has not been reported. Patient 2 ( 12 year old) was hospitalized for limb shaking, hyperspasmia and vomiting. His isosuccinic acid level was 334.3 μmol/L, C3/?C2 rate was 0.37, homocysteine >?65 μmol/L, and had abnormal EEG. MMACHC gene detection found the mutations of c.482G?>?A and c.609G?>?A. Patient 3 was hospitalized for intermittent convulsions for 20 days, whose isosuccinic acid, C3/?C2 rate, and homocysteine were increased. MMACHC gene detection found the mutations of c.394C?>?T and c.540del8 and c.540del8 had not been reported. Review of literatures discovered that MMA was combined with epileptic seizure in some patents, which further validate that the mutation in MMACHC gene c.482G?>?A may be related to the late-onset of cblC. Conclusions Gene detection contributes to the diagnosis of MMA; the mutation of MMACHC gene c.482G>A may be related to the late-onset of cblC; delEXON1 and c.540del8 are new mutations which have not been reported.

Objective To investigate the clinical features of paroxysmal kinesigenic dyskinesia (PKD) and the mutation features of its pathogenic gene proline-rich transmenbrane protein 2 (PRRT2). Method The clinical manifestations and genetic tests of one case of PKD were retrospectively analyzed, and the related literatures were reviewed. Results A 10 year and 9 month male patient was recruited. The age of dyskinesias onset was 7 year and 6 month. The descriptions of the attacks were abnormal involuntary movements which were induced by sudden voluntary movements and presented with dystonia. The frequency of the attacks was three to ifve times per day with the duration lasting ten to twenty seconds, and there is no loss of consciousness. Treatment with oxcarbazepine is effective. A heterozygous mutation in PRRT2 gene, c.649_650insC (p. 217fs224X), was found by genetic testing, and the mutation was inherited from the patient’s mother who showed no symptom of PKD. Conclusion The onset age of PKD could be in the childhood and adolescence. The attack is provoked by sudden movements and the duration time is short. Treatment with antiepileptic drug is effective. The test of PRRT2 gene may help diagnosis. Mutation c.649_650insC is the hotspot mutation of the gene.
