Objective:To explore the effects of acupoint massage combined with transcranial direct current stimulation on cognitive function and quality of life in patients with spontaneous cerebral hemorrhage, to provide direction for early nursing intervention of patients with spontaneous cerebral hemorrhage.Methods:A total of 214 patients with spontaneous cerebral hemorrhage in First Affiliated Hospital of Zhengzhou University from February 2018 to May 2020 were selected as the research objects. They were divided into 2 groups by random number table method: control group (107 cases) and observation group (107 cases). The control group was given transcranial direct current stimulation intervention, and the observation group was given acupoint massage intervention on the basis of the control group. The intervention lasted for 3 weeks. The intervention effects, cognitive function and quality of life of the two groups were evaluated by National Institutes of Health Stroke Scale, Montreal Cognitive Assessment, Stroke Specific Quality of Life Scale and compared.Results:The total effective rate was 91.59%(98/107) in the observation group, 80.37%(86/107) in the control group, and the difference was statistically significant ( χ2 value was 5.583, P<0.05). There was no significant difference in the cognitive function and quality of life before intervention between the two groups ( P>0.05). The visual space and execution, language, abstraction, delayed recall, orientation and total scores after intervention were (2.54 ± 0.51), (2.35 ± 0.37), (1.96 ± 0.31), (2.78 ± 0.38), (2.88 ± 0.41), (17.48 ± 2.01) points in the observation group, and (2.30 ± 0.62), (2.13 ± 0.36), (1.54 ± 0.38), (2.25 ± 0.43), (2.52 ± 0.38), (15.66 ± 1.89) points in the control group, and the differences were statistically significant ( t values were 3.092-9.554, P<0.05). The energy, family role, mood, personality, language, activities, self-care ability, social role, thinking, upper limb function, vision, work/labor and total scores after intervention were (12.85 ± 2.16), (12.94 ± 3.17), (23.46 ± 3.87), (12.53 ± 3.02), (23.76 ± 4.03), (27.52 ± 4.48), (24.92 ± 3.27), (20.94 ± 4.07), (13.15 ± 2.00), (24.54 ± 4.30), (12.20 ± 2.58), (13.54 ± 2.38), (222.35 ± 24.38) points in the observation group, and (10.04 ± 2.02), (10.52 ± 3.03), (21.25 ± 4.02), (11.15 ± 3.00), (21.46 ± 3.31), (24.37 ± 4.32), (22.38 ± 3.05), (18.60 ± 4.02), (12.47 ± 2.05), (22.08 ± 4.21), (11.42 ± 2.63), (11.05 ± 2.51), (197.49 ± 20.06) points in the control group, and the differences were statistically significant ( t values were 2.190-9.829, P<0.05).

Objective To assess the anticonvulsant effect of midazolam, thiopental and propofol on the convulsion induced by ropivacaine in rats and the underlying mechanism.Methods Fifty male SD rats, 4-6 months of age, weighing 250-300 g were randomly divided into five groups of 10 animals each : (1) control group (C); (2) ropivacaine group; (R) (3) midazolam-ropivacaine group (MR); (4) thiopental-ropivacaine group (SR) and (5) propofol-ropivacaine group (PR) . In control group normal saline 2 ml was infused i.v. . In ropivacaine group (R) 0.75% ropivacaine was infused i.v. at 0.5 ml?min-1 until convulsion occurred. In midazolam - ropivacaine group (MR) midazolam 0.23 mg?kg-1 was injected i.v. 3 min before 0.75% ropivacaine infusion. In SR and PR groups thiopental 2 mg?kg-1 or propofol 1 mg?kg-1 was injected i.v. 1 min before 0.75% ropivacaine infusion. As soon as convulsion occurred ropivacaine infusion was stopped. The animals were decapitated and their brains were removed and kept in liquid nitrogen for determination of the contents of excitatory ammo-acids (aspartic acid and glutamic acid) and the inhibitory amino-acids [glycine and ?-amino butyric acid (GABA)] by high-performance liquid chromatography . The amount of ropivacaine infused in each group was recorded and calculated.Results The dose of ropivacaine needed to produce convulsion was 4.6?0.5 mg?kg-1 in group R and was significantly increased in the 3 groups pretreated with general anesthetics and was 2.96 times the dose in group R in MR group, 2.84 times in SR group and 1.54 times in PR group. The 4 amino-acid concentrations in the brain were significantly higher in group R than in control group. Compared to group R the Asp, Gly and GABA concentrations were significantly lower in group MR and PR but in group SR only Asp concentration was significantly lower. There was no significant difference in glutamic acid concentration among the4 roopivacaine groups (group 2-5).Conclusion Midazolam, thiopental and propofol can all increase the dose of ropivacaine needed to induce convulsion and midazolam and thiopental are more effective than propofol.

Objective To explore the current status of sexual education and real needs of college freshmen in Kunming.Methods By applying random sampling,350 students from three universities in Kunming were investigated by seff-administered questionnaire,and 310 valid questionnaires were recovered.Fesults 23.9％ students confirmed that the schools do not provide courses related to sexual health,and 22.9％ of the surveyed students claimed that they even did not heard any sexual education courses in their schools.The main sources of students to acquire information in terms of sexuality and sexual health are network television,video magazines,friends and classmates.Both male and female students are more acceptable to carry out sex education lectures.There were significant differences between male and female students in the form of obtaining sexual education,the content of sexual education and the demand of sexual education in three aspects (P＜0.05).Girls tend to carry out sexual education in the form of major courses,but boys tend to the form of playing video or distributing books and periodicals (P＜0.05).Girls tend to obtain the courses on sexually disease,AIDS,heterosexual intercourse,or love psychology,but boys tend to contraceptive knowledge and skilIs,or Sexual value orientation (P＜0.05).Girls are more likely to acquire the knowledge of masturbation,sexual health,or sexual health,but boys prefer to the knowledge of sexual psychology,parasexuality,or homosexuality (P＜0.05).Conclusion As a main body of educational institute for young people,all universities should provide training courses related to sexuality and sexual health at the early stage of higher education in order to equip college students with essential knowledge and skills to have safer and positive impact on their college studies.

Objective To investigate the influence of different hemostatic way on ovarian function in laparoscopic excision of ovarian cysts. Methods 87 cases with unilateral ovarian cysts by laparoscopic excision were chosen from Jun. 2012 to Jun. 2013 in our hospital, and they were divided into the electrocoagulation group (44 cases) and the suture group (43 cases) according to hemostatic way. The electro-coagulation group were given bipolar coagulation while the suture group were given endoscopic hemostasis. The ovarian hormone levels and blood parameters before and after surgery were compared between the two groups. Results There was no statistically significant differenc in parameters of E2,FSH,LH,P before surgery between the two groups (P>0. 05), and there was no statistically significant differenc before and after surgery in the same group (P>0. 05). Compared with the suture group, there were statistically significant difference in terms of pa-rameters of E2,FSH in the electrocoagulation group(P<0. 05). There was no statistically significant difference in ovary sectional area and PSV between the two groups before surgery (P>0. 05). It was of no statistically significant difference in ovary sectional area between the two groups after surgery (P>0. 05), but it was of statistically significance in PSV (P<0. 05). Conclusion Compared with electrocoagulation, the laparoscopic excision of ovarian cysts with endoscopic hemostasis had less damage to ovarian, and it could protect the ovarian function.

Objective To analyze the clinical characteristics and nursing measures of infection in hospital ICU,and to provide the refer-ence for clinical nursing. Methods From January 2010 to June 2013,116 patients with nosocomial infection in surgical ICU were collected as observation group,and 72 patients with nosocomial infection in the surgery were as the control group. The risk factors of nosocomial infec-tion were retrospectively analyzed,and the problems related to nursing were discussed. Results The nosocomial infection rate was 8. 44% in ICU,which was significantly higher than the surgical infection rate(4. 43%) in general ward (P<0. 05). Whether patients in ICU or surgery ward,respiratory and urinary tract infections were the most common site of nosocomial infection. The mortality rate in ICU was 9. 48%,which was higher than that of nosocomial infection in surgical ward (4. 17%),P<0. 05. The nosocomial infections were obviously related to the age of patients,duration of hospitalization,the invasive operation,antibiotic and immunosuppressive agents and disturbance of consciousness in ICU and general wards (P<0. 01). Conclusion The ICU nosocomial infection rate was significantly higher than that in general ward,the main infection sites are respiratory tract and urinary tract,with a variety of factors,the key is to establish the mechanism of prevention and ef-fective nursing strategy.

ObjectiveTo systemically review the effects of timing of initiation of renal replacement therapy (RRT) on prognosis in septic patients with acute kidney injury (AKI).Methods A systematic search for randomized controlled trials (RCTs) and other clinical studies focused on comparing varied timing of initiation of RRT in septic AKI patients was performed in English or Chinese from PubMed, Web of Science, EMBASE, CNKI, Wanfang data, VIP from January 2000 to July 2014. Data screened were extracted with Cochrane systemically review method, and enrolled literature was collected for Meta analysis with RevMan 5.2 software. Total mortality, 28-day mortality, the total length of hospital stay and intensive care unit (ICU) stay in septic AKI patients with early or late initiation of RRT was analyzed. Funnel plots were drawn to detect publication bias.Results Five retrospective comparative studies with a total of 885 patients were enrolled. Random effect model in Meta analysis showed that there was no significant difference in total mortality between early RRT group and late RRT group [65.7% (226/344) vs. 68.7% (239/348), odds ratio (OR) = 0.71, 95% confidence interval (95%CI) = 0.38-1.31,P = 0.27]. The funnel plot demonstrated publication bias. Fixed effect model showed that there was significant difference in 28-day mortality between early RRT group and late RRT group [43.4% (66/152) vs. 55.3% (94/170),OR = 0.59, 95%CI = 0.36-0.94,P= 0.03]. The funnel plot demonstrated publication bias too. The data of total length of hospital stay and ICU stay could not be Meta-analyzed because of different data distribution, but no differences in total length of hospital stay and ICU stay between early and late RRT groups for septic AKI patients were found.ConclusionEarly RRT could reduce the 28-day mortality in patients with septic AKI compared with late RRT, but it did not lower the total mortality.

Objective To investigate the effects of dexmedetomidine preconditioning on nitric oxide (NO)/endothelin (ET)-1 imbalance and remote lung injury induced by lower limb ischemia-reperfusion (LIR). Methods Sixty patients who scheduled for unilateral lower extremity surgery matched American Society of Anesthesiologists (ASA) Ⅰ-Ⅱ, were randomized into two groups:control group (R group, n=30) and dexmedetomidine preconditioning group (PD group, n=30). Lumbar plexus combined with sciatic nerve block was performed guided by a nerve stimulator in both groups. In group PD, dexmedetomidine intravenous infusion was started at a dose of 0.125 mL/kg (4 mg/L) for 10 minutes before using tourniquet, whereas group R received an equivalent volume of normal saline. Artery blood gas analysis, respiratory index and oxygenation index were measured, and NO, ET-1, interleukin-8 (IL-8) and malondialdehyde (MDA) concentrations were determined from plasma samples 10 minutes before tourniquet inflation (T0), 15 minutes (T1), 2 h (T2), 6 h (T3) and 24 h (T4) after tourniquet deflation. Results Compared with T0, RI was higher at T3 in group R and OI was lower at T2-4 (P＜0.01). There were no significant differences in RI and OI of group PD between different time points (P＞0.05). In R and PD groups, ET-1, IL-8 and MDA concentrations were increased, while NO level and NO/ET-1 ratio were significantly decreased after tourniquet deflation (P＜0.05). Compared with group R, RI was lower and OI was higher at T3 in group PD (P＜0.01). The levels of ET-1, IL-8, MDA, NO and NO/ET-1 ratio were significantly different after tourniquet deflation between group PD and group R (P＜0.05). In group R, there was positive correlation between ET-1 and IL-8 levels with RI, and negative correlation between ET-1 and IL-8 levels with OI (P＜0.01). There was positive correlation between NO level, NO/ET-1 ratio and RI level (P＜0.01). Conclusion Lung function impairment induced by tourniquet application could be attenuated by dexmedetomidine preconditioning based on protecting endothelial cells and inhibiting lipid peroxidation.
