Objective To study the neuropsychological behavior development of preterm infants and low birth weight infants,and to provide a reference to the early prevention and intervention on developmental retardations.Methods A total of 101 preterm infants and/or low birth weight infants received the infant development test of 0 ～ 6 year-old children intelligence developmental scale for neurological development and autism behavior checklist(ABC).Results 25 boys and 5 girls suffered from different psychological mental disorders.The occurrences were as follows:10 cases with mental retardation,9 cases with the language development delay,9 cases with motor retardation,1 case with cerebral palsy and 1 case with autism spectrum disorder.The incidence of intelligence problems were that language retardation (18.9％),the fine motor (16.8％),the adapative ability (12.6％),social action (9.5 ％) and the motor delay (3.2％).There were significant differences in the scores of social communication(x2=8.88,P=0.003),adaptive ability(x2=7.41,P=0.007),the fine motor(x2 =6.22,P=0.01) and total developmental quotient(x2 =5.58,P=0.02) between city children'and rural area.The behavioral problems more consisted in self-care ability and language retardation.Conclusion Preterm infants and low birth weight infants are exposed to language,fine motor,adaptive and communication ability problems,especially the children living in country.It is necessary to improve the early education and intervention for the rural preterm infants and low birth weight infants.

Objective To examine expression of PTEN gene in ovarian cancer cisplatin-sensitive cell line OV2008 cells and cisplatin-resistant cell line C13K cells,and evaluate the effect of wild-type PTEN gene on reversing cisplatin-resistance of C13K cells and underlying mechanisms.Methods The expression of PTEN mRNA and protein in OV2008 and C13K cells were detected by semi-quantitative RT-PCR and western blot.Recombinant eukaryotic expression plasmid containing human wild-type PTEN gene was transfected into C13K cells by lipofectamine 2000.The expression of PTEN mRNA was monitored by RT- PCR and the expression of PTEN,protein kinase B(AKT),phospho-AKT(p-AKT)protein were analyzed by western blot in PTEN transfected and untransfected C13K cells.Proliferation and chemosensitivity of cells to cisplatin were measured by methyl thiazolyl tetrazolium(MTT),and cell apoptosis was detected by flow cytometry after treatment with cisplatin.Results(1)The expression of PTEN mRNA and protein(1.02 ?0.05,1.02?0.07)in OV2008 cells were significantly higher than those in C13K cells,which were 0.45 ?0.03 and 0.55?0.03 respectively(P

Acupuncture has remarkable effects of pain relieving and functional restoration on injuries of soft tissue and joint due to military training. As more and more attention has been attached to the impact of psychological states and biorhythm disorder on the fighting ability of military staff, acupuncture has found its place in treating chronic fatigue, combat stress reaction, traumatic brain injury and post-traumatic stress disorder as well as regulating circadian rhythms. The therapeutic effect of acupuncture in military training-related physical damage and psychological trauma has already been proved by numerous clinical practices and researches. It is held that using acupuncture as an alternative could not only save medical resources, but also enhance the fighting ability of the army. However, the current clinical studies is facing the problem of limited sample size. Therefore, randomized controlled trials in large scale and multiple centers should be further carried out toward military staff, so as to provide more speaking evidences to the prevention and treatment of physical and psychological diseases.

An HPLC method for the determination of geniposide concentration in mouse plasma was developed and the pharmacokinetics after intranasal administration of Xingnaojing microemulsion (XNJ-M) and mPEG2000-PLA modified Xingnaojing microemulsion (XNJ-MM) were investigated. Eighty mice were treated by XNJ-M and XNJ-MM nasally. The plasma samples were collected at different times and the drug in samples was detected by HPLC. The pharmacokinetic parameters were calculated by the software of Kinetica. The pharmacokinetic parameters of geniposide of XNJ-M were C(max) (4.36 +/- 2.69) mg x L(-1), t(max) 1 min, MRT (29.73 +/- 4.54) min, AUC (53.63 +/- 14.03) mg x L(-1) x min. The pharmacokinetic parameters of geniposide of XNJ-MM were C(max) (9.75 +/- 4.14) mg x L(-1), t(max) 1 min, MRT(22.34 +/- 2.90) min, AUC (131.87 +/- 40.13) mg x L(-1) x min. Geniposide can be absorbed into blood in a higher degree after intranasal administration with XNJ-MM compared to XNJ-M, which maybe caused by its less irritating and more absorption.

Objective: To analyze the characteristics, treatment and prognosis in patients with essential thrombocythemia (ET) combining myocardial infarction (MI).
Methods: A total of 10 patients with ET combining MI treated in our hospital from 2003-01 to 2015-07 were retrospectively studied. The basic clinical information with major admission complaints, previous history and peripheral platelet counts were recorded;echocardiograph, coronary angiography (CAG), application of anti-platelet drugs and platelet reductive therapy with the prognosis were recorded in all patients.
Results: There were 6 male and 4 female with a mean age of (55.3 ± 9.7) years, 7 patients with AMI and 3 with old MI. The platelet counts at admission were (500-599) × 109/L in 3 patients, (600-699) × 109/L in 1 patient, (700-799) × 109/L in 3 patients, (800-899) × 109/L in 1 patients, (900-999) × 109/L in 1 patient and more than 1000 × 109/L in 1 patient. Echocardiograph indicated that 5 patient had LVEF≤50%and 5 had LVEF>50%. CAG revealed that there were 9 cases with left anterior descending involved, 2 with circumlfex involved and 5 with right coronary involved. All patients received dual anti-platelet drugs before operation, 4 had hydroxyurea for (20-30) days before operation and no post-operative cardiovascular events occurred;6 patients without hydroxyurea medication and 1 of them was re-hospitalized for angina pectoris and 2 had progressed coronary lesions.
Conclusion: Application of platelet reductive therapy at before and after interventional treatment may improve the prognosis in patients with ET combining MI.

Objective:To study the effect of Huanglian-Jiedu Decoction on the white matter lesion of rats with focal cerebral ischemia and to explore the regulative role of the active fraction of Huanglian-Jiedu Decoction on NogoA/NgR. Methods:Male SD rats were randomly divided into sham operation group, model group, total alkaloid group, total flavonoid group, and total iridoid group. Except for the sham operation group, the rats in the other groups were used to establish the middle cerebral artery occlusion rat model by the suture method. 2 hours after modeling, rats in the total alkaloid group were given intragastric administration with 44 mg/kg total alkaloids; rats in the total flavonoid group were given intragastric administration 50 mg/kg total flavonoids; rats in the total iridoid group were given intragastric administration 80 mg/kg total iridoids, the sham operation group and the model group were intragastrically given equal volume of normal saline, once a day, for 7 consecutive days. The pathological changes of rat white matter were observed by HE staining, the pathological changes of rat myelin sheath were observed by Luxol fast blue (LFB) staining, and the expression of Amyloid precursor protein (APP), NogoA, and NgR in the internal and external capsule areas of the brain was detected by immunohistochemical staining. Real-time fluorescence quantitative PCR was used to detect the expression of NogoA and NgR in the tissues surrounding the ischemic infarct.Results:Compared with the model group, the total alkaloid group, total flavonoid group, and total iridoid group had lower pathological damage scores in the internal and external capsule areas of rats ( P<0.05 or P<0.01), increased integral optical density value of LFB staining ( P<0.01), decreased expression of APP and NogoA; the expression of NgR in the internal and external capsules of rats in the total alkaloid group and the total iridoid group decreased ( P<0.05 or P<0.01), and the expression of NgR in the inner capsule of rats in the total flavonoid group decreased ( P<0.01); the expression of NogoA (1.20 ± 0.17, 1.55 ± 0.30, 1.19 ± 0.38 vs. 2.22 ± 0.58) and NgR (1.98 ± 0.55, 1.48 ± 0.31, 1.58 ± 0.27 vs. 3.36 ± 0.41) genes in the tissues around the infarct focus of rats in the total alkaloid group, total flavonoid group and total iridoid group decreased ( P<0.01). Conclusion:The present study investigates the therapeutic effects of Huanglian-Jiedu Decoction, promoting white matter repair by decreasing the overexpression of NogoA and NgR in an experimental animal model of stroke.
