Objective To investigate the nursing method to spine surgery inpatients suffering postoperative cognitive dysfunction. Methods Nineteen spine surgical patients who had postoperative cognitive dysfunction were closely observed , and special nursing measures such as cognitive behavioral intervention, save care, sleep care and comfort care were taken. Results Patients' mental symptoms lasting 3 ～ 10 days lessened gradually after receiving specific treatment and nursing. 15 Discharged Patients were followed up. Their cognitive dysfunction could improve gradually and could be recovered at last. Conclusions Postoperative cognitive dysfunction after Spine surgery can be found more easily in old patients. Careful observation and active nursing intervention can reduce the cognitive damage of POCD patients and promote their recovery effectively.

OBJECTIVETo investigate the effect of nano-TiO(2) intratracheal instillation on the progression of dyslipidemia and atherosclerosis in apolipoprotein E-knockout mice.

METHODSThe nano-TiO(2) was ultrasound with phosphate-buffered saline solutions (PBS) into its suspension for exposure. A total of 46 specific pathogen free (SPF) level of 11-week-old male apolipoprotein E-knockout mice were randomly divided into groups by their body weights: non-treatment group (8 mice), PBS control group (9 mice), high dose group (1.0 mg/ml, 10 mice), medium dose group (0.5 mg/ml, 10 mice), and low dose group (0.1 mg/ml, 9 mice). Except the non-treatment group, mice from other groups were intratracheally instilled with 0.05 ml each time, twice a week. After exposure of 6 weeks, viscera index, blood TC, TG, HDL-C, LDL-C, and organic lipid ratio were assessed as biomarkers. Artery and aortic root issues were assessed by histopathology.

RESULTSAfter 5 weeks exposure, mice body weights in high dose group ((29.7 ± 1.9) g) started to drop, compared to PBS control ((31.3 ± 1.9) g, t = -1.58, P < 0.05) and low dose group ((31.4 ± 1.4) g, t = -1.17, P < 0.05); after 6 weeks, high dose group ((28.8 ± 1.5) g) was lower than PBS control ((30.4 ± 1.9) g, t = -1.60, P < 0.05), non-treatment group ((30.2 ± 1.3) g, t = -1.43, P < 0.05) and low dose group ((30.6 ± 1.0) g, t = -1.83, P < 0.05). TC levels of non-treatment, PBS control, high dose group, medium dose group and low dose group were (2.92 ± 1.18), (3.12 ± 0.73), (4.19 ± 1.86), (3.46 ± 0.72) and (2.57 ± 0.64) mmol/L, respectively; TG levels were (0.39 ± 0.13), (0.39 ± 0.08), (0.60 ± 0.21), (0.55 ± 0.19) and (0.41 ± 0.11) mmol/L, respectively; HDL-C levels were (1.67 ± 0.45), (1.54 ± 0.67), (0.93 ± 0.50), (1.02 ± 0.48) and (1.31 ± 0.64) mmol/L; TG levels of high dose group were higher than that of non-treatment group (t = 1.27, P = 0.03) and low dose group (t = 1.62, P = 0.01); TG levels of medium dose group was higher than PBS control (t = 0.16, P = 0.04), and TC levels of high dose group were higher than PBS control (t = 0.22, P = 0.01), non-treatment group (t = 0.22, P = 0.04) and low dose group (t = 0.20, P = 0.03), and HDL-C levels of high dose group were lower than PBS control (t = -0.61, P = 0.04) and non-treatment group (t = -0.74, P = 0.04); organic lipid ratio of each group were (2.27 ± 0.51)%, (2.06 ± 0.53)%, (2.90 ± 0.50)%, (2.60 ± 0.23)%, (2.24 ± 0.45)%; high dose group were higher than PBS control (t = 0.85, P = 0.00), non-treatment group (t = 0.64, P = 0.03) and low dose group (t = 0.67, P = 0.01); medium dose group was higher than PBS control (t = 0.54, P = 0.02). The plaque lipid content and calcium content which showed the progression of atherosclerosis and plaque rupture were elevated in medium and high dose groups.

CONCLUSIONIntratracheal instillation of nano-TiO(2) can induce dyslipidemia and accelerate the development of atherosclerosis and plaque rupture in ApoE-/-mice.

OBJECTIVETo summarize the results and experiences on extracorporeal membrane oxygenation (ECMO) for post-cardiac surgery of coronary artery disease.

METHODSFrom June 2004 to November 2006, sixteen patients with the mean age of (58 +/- 11) years old undergoing cardiac surgical procedures were placed on ECMO using a heparin-bonded circuit. Fourteen patients were male and two patients were female. Thirteen patients underwent on pump coronary artery bypass surgery (CABG) and three patients underwent off-pump coronary artery bypass grafting. The duration of ECMO support, stay of intensive care unit (ICU stay), complications and turnovers were recorded.

RESULTSThe mean duration of ECMO support was 51 hours, and the mean duration of ICU stay was 5 days. Thirteen patients (81.3%) were successfully weaned form ECMO, ten patients (62.5%) were discharged from hospital. The main complications were bleeding, infection, renal failure and ischemia of the lower limbs with the incidence of 18.8%, 37.5%, 25% and 18.8% respectively.

CONCLUSIONECMO is an acceptable technique for shortterm treatment of refractory low cardiac output after cardiac surgery of coronary artery disease.

OBJECTIVETo investigate the anti-angiogenic effects of Pien Tze Huang in vivo and in vitro.

METHODSHuman umbilical vein endothelial cells (HUVECs) were treated with 0 mg/mL, 0.25 mg/mL, 0.5 mg/mL, and 1 mg/mL of PZH for 24 h, 48 h and 72 h, respectively. Chicken embryo chorioallantoic membrane (CAM) model was used to evaluate in vivo angiogenesis. An ECMatrix gel system was used to evaluate in vitro angiogenesis by examining the tube formation of HUVECs. 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay was performed to determine HUVEC viability. Cell density of HUVECs was observed by phase-contrast microscopy. HUVEC migration was determined by wound healing method. The mRNA and protein expression of vascular endothelial growth factor A (VEGF-A) and basic fibroblast growth factor (bFGF) in both HUVEC and human colon adenocarcinoma cells (HT-29) was examined by reverse transcription polymerase chain reaction (RT-PCR) and enzyme linked immune sorbent assay (ELISA), respectively.

RESULTSPZH treatment significantly reduced the total number of blood vessels compared with the untreated control in the chicken embryos and resulted in a significant decrease in capillary tube formation and cell density of HUVECs (P<0.05). In addition, treatment with 0.25-1 mg/mL of PZH for 24 h, 48 h, and 72 h respectively reduced cell viability by 9%-52%, 24%-87% or 25%-87%, compared with the untreated control cells (P<0.05). Moreover, PZH treatment decreased the migration of HUVECs. Furthermore, PZH dose-dependently suppressed the expression of VEGF-A and bFGF on both mRNA and protein levels (P<0.05).

CONCLUSIONPZH could inhibit angiogenesis in vivo in CAM model and in vitro on HUVECs, suggesting that inhibiting tumor angiogenesis might be one of the mechanisms by which PZH treats cancer.

Objective To explore the association between the severity of scrub typhus (ST) and the serum procalcitonin (PCT) level. Methods The clinical data of 58 ST patients who were treated in the First Affiliated Hospital of Xiamen University and confirmed by Xiamen Municipal Center for Disease Prevention and Control (CDC) from January 2016 to October 2017,were retrospectively analyzed. According to clinical manifestations and related laboratory tests,these patients were divided into four grades:Ⅰ,Ⅱ,Ⅲ,and Ⅳ. These four grade groups were compared in terms of age,interval from symptom onset to hospital presentation,hospitalization days,and serum PCT level. Results These 58 patients were divided into four grade groups:grade Ⅰ group (n=17),grade Ⅱ group (n=17),grade Ⅲ group (n=11),and grade Ⅳ group (n=13). No significant difference was found among these four groups in terms of age (F=0.618,P=0.606),interval from symptom onset to hospital presentation (F=1.744,P=0.169),and hospitalization days (F=0.398,P=0.755).However,the median serum PCT level in the grade Ⅳ patients[2.60(1.33,61.08)ng/ml] was significantly higher than those in grade I[0.24(0.10,0.33)ng/ml;Z=-4.63,P=0.000], grade Ⅱ[0.29(0.21,0.51)ng/ml;Z=-4.63,P=0.000], and grade Ⅲ[1.33(0.89,2.41)ng/ml;Z=-2.09,P=0.040].The median serum PCT level in the grade Ⅲ patients was also significantly higher than grade Ⅰ (Z=-4.16,P=0.000)and grade Ⅱ(Z=-3.83,P=0.000).There was no significant difference between the grade Ⅰ patients and grade Ⅱ patients(Z=-1.37,P=0.170).There was significantly positive correlation between PCT level and the severity of ST (r=0.804,P=0.000).Conclusion There is positive correlation between serum PCT level and the severity of ST,and serum PCT level may be a biomarker in assessing the severity of ST.
