Objective To observe the regulatory effects of the preventive acupuncture and moxibustion at Guanyuan (RN4) points in ovariectomized rats, and discuss the mechanism of preventive acupuncture and moxibustion on hyoathalamus-pituitary-ovary (HPO) axis. Methods Totally 48 female SD rats were divided into 5 groups, including normal group, sham operation group, ovariectomized rats group, preventive acupuncture group and preventive moxibustion group. Except normal group and sham operation group, rats were ovariectomized after preventive acupuncture and preventive moxibustion for 30 d in corresponding groups. ELISA was used to determine the levels of E2, ER, GnRH, FSH and LH in the tissues including hypophysis, hypothalamus and uterus. Results Compared with the normal group, E2, ER and GnRH level in the tissue of the model group was significantly lower (P<0.01), the levels of FSH and LH increased obviously (P<0.01). Compared with the model group, E2, ER and GnRH level of preventive acupuncture group and preventive moxibustion group increased in different degree (P<0.05). FSH and LH level reduced in different degree (P <0.05). There was no obvious difference between preventive acupuncture and preventive moxibustion group (P>0.05). Conclusions The preventive acupuncture and preventive moxibustion at Guanyuan (RN4) has benign modulation to disordered HPO axis of ovariectomized rats. The ability of preventive acupuncture and preventive moxibustion are almost the same.

Objective To investigate the effect of treadmill running pretreatment on the expression of CyclinA and CyclinE protein in hippocampus of rats after global cerebral ischemia and reperfusion.Meth-ods 60 healthy male wister rats were randomly divided into control group, model group and experiment group.Global cerebral ischemia reperfusion model was generated by improved four-vessel occlusion as de-scribed according to the description of Pulsinelli's method.Rats in the experiment group were performed treadmill running for 2 weeks before injury.The water maze test was performed at 24 h and 48 h respectively after injury to determine the spatial memory ability of rats.Morphological changes of hippocampus were ob-served by HE staining ( hematoxylin-eosin staining) at 3 h,6 h,24 h,48 h after injury and the expression of CyclinA and CyclinE were detected by immunohistochemical staining.Results Compared with control group,the survival rate of neurons in the model group was significantly decreased at each time point.Morris water maze test showed that the escaping latency of rats in the model group was significantly prolonged( 24 h (24.35±3.99)s,48 h(33.08±5.85)s),and the frequency of crossing the platform was decreased(24 h(6.80 ±0.79),48 h(4.00±0.67)).The expression of CyclinA was increased significantly in the model group ((8.40±0.52)/high view,(11.70±1.06)/high view,(15.50±0.53)/high view,(22.40±0.52)/high view) as well as the expression of CyclinE((20.30±0.48)/high view,(15.20±0.63)/high view,(10.00± 0.82)/high view,(7.70±0.68)/high view) (P<0.05).Compared with model group,the survival rate of neurons in the model group was significantly increased at each time point.Morris water maze test showed that the escaping latency of rats in the experiment group was significantly shorten(24 h(13.21±2.73) s,48 h (24.20±4.66)s),and the frequency of crossing the platform was increased(24 h(9.70±0.95),48 h(6.30± 1.16)).The expression of CyclinA was significantly increased in the model group((10.60±0.84)/high view),(16.70± 0.68)/high view),(24.50±0.53)/high view),(36.20±1.40)/high view) as well as the expression of CyclinE((31.60 ±0.70)/high view),(24.50±0.70)/high view),(16.80±0.63)/high view),(9.10±0.74)/high view) (P<0.05).Con-clusion The treadmill running pretreatment improves the function of spatial memory after global cerebral ischemia and reperfusion,potenlially mediated by regulating the expression for cell cycle proteins,which have a protective effect on cerebral brain tissue.

Objective To investigate the prenatal diagnosis and prenatal genetic conselling of pseudomosaic trisomy 20. Methods One case of pseudomosaic trisomy 20 was analyzed and relative literatures were reviewed. Results A 31-year-old gravid 1, para 0 woman underwent amniocentesis at 18 weeks of gestation due to high risk of trisomy 21 during maternal serum screening in September, 2012. Interphase fluorescence in situ hybridization (FISH) of amniocytes with probes GLP13/GLP21/CSP18/CSPX/CSPY showed a normal result, while cytogenetic analysis of cultured amniocytes revealed a karyotype of 47,XY,+20[7]/46,XY[9]. The level of trisomy in the cultured amniocytes was 7/16. Cordocentesis revealed a karyotype of 46,XY in cultured cord blood cells. Interphase FISH analysis was performed using the probes D20Z1 (20p11.1-q11.1) and D20S1157/20QTEL14 (20 per/qter). Each probe showed two signals in all uncultured amniocytes. The prenatal ultrasound findings were unremarkable. The mosaicism was considered to be pseudomosaicism. After genetic counseling, the parents selected to continue the pregnancy. A healthy male baby was delivered at 39 weeks of gestation. Postnatal cytogenetic analysis revealed a karyotype of 46,XY in peripheral blood lymphocytes. Interphase FISH analysis of the uncultured buccal cast-off cells using the probes D20Z1 and D20S1157/20QTEL14 showed normal results in 100%cells. There was no phenotypic abnormality at the age of seven months. Conclusions When mosaic trisomy 20 is identified in amniocytes, further evaluation and genetic counseling are required. Interphase FISH of the uncultured amniocytes with a chromosome-specific probe is a useful tool for confirmation of the prenatal diagnosis of mosaicism. Genetic analysis of multiple tissues is required postnatally.

Objective To investigate the expression of granulocyte macrophage-colony stimulating factor(GM-CSF)in skin lesions and sera of patients with pustular psoriasis and psoriasis vulgaris.Methods Tissue specimens were obtained from the lesions of 15 patients with pustular psoriasis,15 patients with psoriasis vulgaris and 15 normal human controls.Immunohistochemistry and dual antibody sandwich enzyme-linked immunosorbent assay(ELISA)were carried out to detect the levels of GM-CSF in the tissue and serum specimens from the patients and normal human controls,respectively.Results Significantly higher levels of GM-CSF were observed in the tissue and serum specimens from patients with pustular psoriasis and psoriasis vulgaris compared with the normal controls(all P ＜ 0.01),as well as in those from the patients with pustular psoriasis compared with the patients with psoriasis vulgaris(both P ＜ 0.01).Conclusion GM-CSF may be involved in the pathogenesis of psoriasis.

Objective To investigate the efficacy and safety of amisulpride and clozapine in schizophrenia patients with predominantly negative symptoms.Methods Totally 166 cases of schizophrenia patients with predominantly negative symptoms from May 2013 to May 2016 in The Sixth People's Hospital of Hebei were divided into observation group and control group,83 cases in each group.Patients in the observation group were treated with amisulpride,and control group were treated with clozapine.The clinical effect,SANS scores,and occurring rate of abnormal electrocardiogram were compared.Results The clinical effect,emotional insipid (blunting),and attention dysfunction scores from SANS of observation group were significantly better than those of control group on week 4,8,and 12,respectively (P ＜ 0.05);The occurring rate of abnormal electrocardiogram in observation group was significantly lower than that of control group on week 12 (P ＜ 0.05).Conclusion Compared with clozapine,amisulprid has better efficacy and safety in schizophrenia patients with predominantly negative symptoms,and can effectively improve of symptom of insipid (blunting) and attention dysfunction.

A strain was separeted from the Yueqing bay using pine pollen baiting.The vegetative thallus of the separated strain is oval and unincleate.It possesses a cell wall composed of many compact layers of closely pressed scales, which can be resolved where the cell wall is disrupted.The radiating branched extensions of the thallus, the ectoplasmic net, emerges from the sagenogenetosome.Asexual reproduction is by conversion of the vegetative thallus to many biflagellate zoospores, during which tetrads of cells are formed.It was identified with Schizochytrium sp.based on the features mentioned above.

To explore the depression in type 2 diabetic patients treated with insulin and compared to those treated with oral anti-diabetic drugs.283 type 2 diabetics were seclected randomly from outpatient and inpatient departments of endocrionology in Jiangsu Province Hospital of Traditional Chinese Medicine,with the self-designed questionnaire and Zung self-rating depression scale to conduct the survey.Comparisons between the two groups were carried out with t-test or x2 test for quantitative and qualitative data,respectively.Logistic regression were used for the analysis of the relationship between the therapeutic regimen and depression.Overall,43.1％ of the type 2 diabetic subjects showed depressive symptoms in different degrees.Compared to the oral drug group,the insulin group showed a significantly higher prevalence of depressive symptoms (insulin group,53.5％,oral drug group,30.5％;P＜0.01)and higher self-rating depression scale scores (insulin group,51.7 ± 12.4,oral drug group,44.8 ± 10.6;P＜0.01).Moreover,after an adjustment for age,sex,body mass index,diabetic duration,complications,HbA1Cand so on,the insulin group showed a significantly higher frequency of depression (OR=4.218,95％ CI 1.764-13.285,P=0.004),compared to the oral drug group.The data showed that insulin treatment is an independent risk factor to the presence of depressive symptoms in type 2 diabetics,and it is necessary to pay more attention to their psychological support.

Objective To analyze the relationship between karyotypes and clinic features of patients with primary amenorrhea. Method Karyotype analysis of patients with primary amenorrhea was performed by using G-banding technique. Results Karyotype analysis of 468 patients with primary amenorrhea revealed that 255 patients (54. 49% ) had normal female karyotypes and 213 patients (45.51%) had abnormal karyotypes, including 143 patients with abnormal X chromosome, 4 patients with mosaic X -Y chromosome, 57 patients with 46, XY karyotype, 8 patients with abnormal autosome and one patient with Xautosome translocation. 75.52% primary amenorrhea patients with short stature had abnormal X chromosome, and all primary amenorrhea patients with deletion or break-up of Xp11. 1 - 11.4 and Xp21 - 22 were short statures. Conclusion One of the main reasons of primary amenorrhea was chromosome abnormity,especial heterosome abnormity. Karyotype analysis should be used to detect primary amenorrhea patients in regular. There might be relationship between height improvement and the abnormity of Xp11. 1 - 11.4 and Xp21 - 22.
