Chinese Journal of Practical Nursing 2016;32(34):2684-2686
Objective To observe whether the high-flow nasal cannulae (HFNC) can reduce the rate of re intubation after extubation in patients with tracheal intubation in the intensive care unit (ICU). Methods 134 patients with mechanical ventilation in ICU were divided into 2 groups according to the order of ICU. The control group and the observation group were divided into 67 groups. Patients in control group were used routine oxygen inhalation (nasal duct and mask) after weaning, while the observation group was HFNC. All the other patients with the same treatment and care. The rate of re intubation was compared between the 2 groups. Results In the observation group, the rate of reintubation was 4.48%(3/67) of all. The control group was 14.92%(10/67), two groups of patients with reintubation rate difference was statistically significant (χ2= 4.17, P < 0.05). Conclusions HFNC can decrease the rate of re intubation after extubation in patients with tracheal intubation.

Objective To analyze the discourse right construction of China’s medical aid to Africa,so as to provide evidenc?es for improving the effect and sustainable development of China’s medical aid to Africa. Methods The documents of the dis?course right that China constructed in the medical aid to Africa were selected at different periods as discourse samples. The achievement and deficiency were analyzed from four aspects,namely confident,charismatic,influential,and dominant. Re?sults China’s medical team made much in the discourse right construction in their aid to Africa,but some China’s medical team members were still too cautious and too low?key. China’s medical team gained the trust of the people of Africa,but the lan?guage communication difficulties still hampered in China’s medical aid to Africa. Chinese medical team were widely praised by the African society,but in the west,some African media,even China’s media still neglected to report China’s doctors. China’s international discourse right were greatly improved,but western countries still dominated the public opinion. Conclusion Chi?na should refer to the actual situation of medical aid to Africa to strengthen the construction of discourse right.

Objective To investigate the expression and significance of β-catenin and peroxisome prolifera-tot-activated receptor-γ,(PPARγ) in bepatocellular carcinoma. Methods Tissue microarrays were established to detect β-catenin and PPARγ expression in 49 cases of hepatocellular carcinoma,49 cases of adjacent nontumoral liv-er tissue and 6 cases of normal liver tissue. The relationships between PPARγ and β-catenin as well as between PPARγ and clinicopathological parameters were observed. Results The aberrant expression rate of β-catenin was 69.39%,48.98 % and 0 respectively (P=0.001). The positive expression rate of PPARγ was 51.02%,30.61% and 0 respectively (P=0.016). Clinicopathological analysis revealed that the increase of PPARγ expression was not associated with age,tumor size,serum alpha fetoprotein (AFP) levels,tumor embolus of portal vein or inferior vena cava,and HBsAg infection(χ2=0.214,3.201,0.046,3.201,P>0.05 for each),but correlated with differentiation grades(χ2=4.693,P<0.05). Aberrant expression of β-catenin was associated with PPARγ expression(χ2= 5.130,P<0.05). Conclusion Aberrant expression of β-catenin may involve in the liver carcinogenesis. The high expression of PPARγ in hepatocellular carcinoma is significantly correlated with the clinicopathological characteris-tics. Detection of PPARγ is valuable for diagnosing hepatocellular carcinoma,and evaluating malignancy extent and prognosis.

Objective: To examine the microbial flora within the root canals with failed root canal therapy by PCR test, to identify detection rate of bacteria and the predominant bacteria species, and to determine the association of the various species with clinical features. Methods: Forty roots with failed root canal therapy were selected for this study. According to clinical features the roots were divided into three groups: pain, fistula and symptomless. After removal of the root filling material, the microbial samples were taken from the canal and detected by PCR test. Results: The microbial flora within root canals of teeth with failed root canal therapy was found to be mixed, six kinds of bacteria were detected. Enterococcus faecalis was the most commonly recovered bacteria species. Significant associations were observed between Prevotella nigrescens and pain, while dependablity was observed between Actinomyces israelii and fistula. Conclusion: The main cause of root canal treatment failure is the persistent microorganisms. The composition of bacteria in teeth with failed root canal therapy has its own specificity.

Transcuataneous electrical nerve stimulation (TENS) analgesia as a non-drug method has received people's more and more attention recently. Considering problems of existing products, such as unstable performance and unsatisfied effectiveness, we developed a new analgesia therapy system for delivery based on bio-feedback TENS in our laboratory. We proposed a new idea for stimulation signal design, that is, we modulated a middle frequency signal by a traditional low frequency TENS wave in the new system. We designed different prescription waves for pain relief during a uterine contraction or massage between contractions. In the end, a bio-feedback TENS method was proposed, in which the waveforms of stimulation signals were selected and their parameters were modified automatically based on feedback from uterine pressure, etc. It was proved through quality tests and clinical trials that the system had good performance and satisfied analgesia effectiveness.

With the Meta-analysis method, the clinical efficacy of acupuncture and other regular methods for aphasia was evaluated, and the acupoints selection for aphasia was explored. The acupuncture literature of clinical randomized control trials for aphasia published in CNKI, WANFANG, VIP and CBM database was searched; the statistical analysis of clinical efficacy of acupuncture and other regular methods for aphasia was performed by using software Revman 5. 2 provided by Cochrane library. A file of Microsoft Excel was established to perform the analysis of acupoints selection based on frequency analysis method, so as to summarize the characteristics and rules. Totally 385 articles were searched, and 37 articles those met the inclusive criteria was included, involving 1,260 patients in the acupuncture group and 1 238 patients in the control group. The Meta-analysis results showed OR = 3.82, 95% Cl [3.01, 4.85]; rhombus was located on the right side and the funnel plot was nearly symmetry, indicating the treatment effect of the acupuncture group for aphasia was superior to the control group (Z = 11.04, P < 0.000 01). The frequency-analysis results showed that the frequency of acupoints from top to bottom was Lian-quan (CV 23), Tongli (HT 5), Yamen (GV 15), Jinjin (EX-HN 12), Yuye (EX-HN 13), Baihui (GV 20), Yuyan II, Yuyan I and Yuyan III. The frequency of meridians from top to bottom was the governor vessel, extra channels, conception vessel, heart meridian and large intestine meridian. It is concluded that the clinical efficacy of acupuncture combined with speech rehabilitation training and medication treatment for aphasia is superior to that of speech rehabilitation training and medication treatment alone. The clinical treatment for aphasia focuses on its local effect; the main acupoints are in the head and face, and the meridians are governor vessel, extra channels and conception vessel.

Objective:To evaluate the left ventricular rotation and twist in patients with constrictive pericarditis (CP) after pericardiectomy by using speckle tracking echocardiography (STE), and observe its trend over time.Methods:A total of 29 patients with CP from Department of Medical Ultrasound, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from September 2014 to December 2017 underwent echocardiography 1 week before and 1 month, 6 months, 12 months after pericardiectomy. STE was performed to obtain peak values of basal and apical rotation and left ventricular twist. Twenty-nine healthy subjects were recruited as controls in the same period.Results:The left ventricu1ar apical rotation[before surgery(6.62±3.19)°, 1 month after surgery(7.07±4.02)°, 6 months after surgery(7.88±4.46)°, 12 months after surgery(7.85±4.51)°], the left ventricu1ar twist [before surgery(10.50±4.94)°, 1 month after surgery(9.42±5.40)°, 6 months after surgery(9.59±4.62)°, 12 months after surgery(9.70±4.45)°] were significantly lower in patients with CP than those in controls [(11.22±5.17)°, (16.35±5.21)°](all P<0.05); while basal rotation in patients with CP after surgery among different time points were all significantly lower than those in controls[1 month after surgery(-3.85±3.20)°, 6 months after surgery(-3.49±2.09)°, 12 months after surgery(-3.53±2.01)°; controls(-5.57±2.78)°] (all P<0.05), with no significant difference between patients with CP before surgery (-5.22±3.14)° and controls (-5.57±2.78)°( P>0.05). There were no significant differences in left ventricular twist, basal and apical rotation in CP groups before and after surgery among different time points (all P>0.05). Conclusions:Although the left ventricular global function of patients with CP in the long postoperative period seems "normal" , the left ventricular twist, basal and apical rotation are still significantly lower than those in controls. STE can be used to assess the changes of left ventricular twist and rotation in patients with CP long-term after pericardiectomy.
