China Medical Equipment 2017;14(8):144-147
Objective:To explore the status and characteristic of psychology for primipara and gravida with second child so as to improve psychological status of them and take them keep positive mentality in whole gestation.Methods: 176 gravidas randomly were selected in this study, and a self-designed questionnaire of psychology was applied to evaluate and compare the psychological status and self-care capacity between primipara and gravida with second child by using method of questionnaire survey. The primipara and gravida with second child were implemented hierarchical management depended on their differently psychological problem, and personalized intervening measurement was adopted to enhance their self-care capacity.Results: The psychological enduring capacity, self-care capacity and the ability of deal with problem about interpersonal relationship of gravidas with second child were obviously better than that of primiparas, while the neglect degree for antenatal care of them was higher than that of primiparas.Conclusion: The whole society should pay attention to the process for gestation of pregnant woman, and give them higher social support so as to promote the maternal and child health and effectively decrease the occurrence rate of delivery risk.

Objective To study the effects of estrogens ( 17α-ethynylestradiol and 17β-estradiol ) on the ATP-sensitive potassium channel ( KATP ) activities in the enzymatically ( collagenase and protease ) isolated ICR mouse ventricular cardiomyocytes using inside-out and cell-attached patch clamp techniques .Methods In the inside-out patch configurations, the two estrogens reduced the K ATP channel activities in a dose-dependent manner at -60 mV holding potential ( HP) .Results The half-maximal inhibitory concentration ( IC50 ) of the 17α-esthynylestradiol and the 17β-estradiol were 0.3μmol/L and 0.1 nmol/L, respectively.However, these agents had no effects on the pinacidil-and DNP-induced KATP channel activities in the cell-attached patch configuration.However, the inhibitory effect of KATP channel activities by the 17-estrogens or the anti-estrogens in the excised inside-out patch configuration were abolished by 1 pmol/L PDBu.Conclusions The results of this study demonstrate that some estrogens decrease the K ATP channel activity acting on the inside of the isolated cardiomyocytes , and play a protective role to cardiomyocytes .

Objective To evaluate the relative quantities of flt-1, KDR, endostatin mRNA in tissue specimens of human hemangioma and great saphfenous vein with the modified reverse transcriptase-polymerase chain reaction (RT-PCR). Methods Total RNA from human specimens by Trizol was reverse-transcribed and amplified by PCR in 4 deffirent tubes containing one of the primer pairs such as flt-1, KDR, endostatin or ?-actin. The target genes and beta-actin PCR products were about 200 bp in length. The ratio of the yield of the target gene PCR product to the beta-actin PCR product could be calculated after 35 cycles of amplification.Results These ratios were correlated positively ( P=0.014,P=0.019) in two groups, but no relationship in endostatine level was observed (P=0.436).Conclusions VEGFR may play a very important role in the pathogenesis of the congenital hemangioma in children. But the endostatin may take little effect on it.

Aim The goal is to make a further comprehension of the pathogenesis of Parkinsons disease (PD) and hence add further knowledge for PD diagnosis by observing the functions of nitric oxide (NO) in striatum (STR). Method Microelectrodes were used to observe the effects of sodium nitroprusside (SNP), L-glutamic acid (GLU) and ?-aminobutyric acid (GABA) on STR neurons' spontaneous firing rates, and at the same time, we observed the effects of NO on GLU and GABA. Results 77% (51/66) of the tested neurons were excited by SNP, NO synthase inhibitor L-NAME antagonized the excitatory effect of SNP. Duringthe periods of microelectrophoresis GLU and GABA, SNP amplified the excitatory effect of GLU and weakened the inhibitory effect of GABA. L-NAME antagonized the excitatory effect of GLU.Conclusion These results demonstrated clearly that NO, GLU and GABA functions might converge in the same STR neurons. NO and GLU functions are excitatory whereas GABA function is inhibitory on the firing activities in STR neurons.

Objective To explore the relationship among psychological empower,role stressors and job burnout in doctors.Methods According to convenience sampling principle,350 doctors were selected and assessed with the job burnout scale (MBI-GS),the psychological empower scale and role stressors scale.Results The scores of meaning(10.80±3.12) and self-determination (9.33 ± 3.19) were negatively correlated with the scores of job burnout (r value was from-0.28 to-0.47,P<0.01),the scores of self-efficacy(11.42±2.67)were negatively correlated with the scores of cynicism (1.61 ± 1.21)and reduced personal accomplishment (3.62±1.51)(r=-0.23,-0.51,P<0.01),and the scores of impact(8.04±3.18) were negatively corrclated with the scores of emotional exhaustion(1.89±1.19) and cynicism(r=-0.17,-0.25,P<0.01).The scores of role stressors were positively correlated with the scores of emotional exhaustion and cynicism(r=0.15-0.45,P<0.01),and the scores of role ambiguity(19.09±3.76) were positively correlated with the scores of reduced personal accomplishment (r=0.42,P<0.01).The self-efficacy and self-determination can negatively predict job burnout(P<0.01) ;the role overload(15.24±4.62) and role ambiguity can positively predict job burnout(P<0.01).Conclusion Psychological empower and role stressors are closely related with job burnout,and have significantly predictive effects on job bumout.

Objective To study the 2244G→A, 2299 A→G single nucleotide polymorphism (SNP) in the 5' regulatory regions of Toll-like receptor 4 (TLR4) in patients with Gram negative bacteria infection in Shenzhen locality, and to discuss the occurrence, course and prognosis of patients with sepsis. Method Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used to detect the genotype of TLR4. After the whole blood DNA of patient was extracted and PCR was amplified, the products were 500bp and 599 bp, and were cut by endonuclease Mae Ⅱ and Sph Ⅰ respectively to determine the SNP 2244G→A and 2299 A→G in TLR4. These two kinds of allele frequencies were statistically calculated in all patients. In the meantime, the incidence of septic shock, average hospitalized days, cost and prognosis of all patients were recorded. Statistical analysis was performed with SPSS version 16 software. ANOVA was used for comparison among multiple groups, and t -test and Sighed rank test were used for paired comparison. Results The 2299 and 2244 sites in the 5' regulatory regions of TLR4 gene of patients with Gram negative bacteria infection in Shenzhen locality had various degrees of changes in single nucleotide. Compared with the documented data from Chinese people in general, there was a significant difference in 2299A→G genotype frequency in residents of Shenzhen locality ( P < 0.05). But there were no statistically significant difference in mortality, incidence of septic shock, average days of ICU stay or ICU cost between TLR4 SNP positive and negative groups of patients. Conclusions There is a wide range of genetic variation in the 2299 and 2244 sites in the 5' regulatory regions of TLR4 among citizens of Shenzhen locality with unique distribution. The 2299A→G genotype frequency probably has differences in distribution and population. The pathogenesis and the prognostic factors of sepsis are complicated, whereas the gene polymorphism may be just one of the factors affecting the prognosis of patients with Gram negative bacteria infection.
