Objective To assess the effect of thoracoscopic surgery under laryngeal mask anesthesia and explore the nursing strategies. Methods Thirty-five patients from April to December in 2014 undergoing video-assisted thoracoscopic surgery (VATS) were given intubation anesthesia and another thirty-five ones undergoing the same surgery in 2015 received laryngeal mask anesthesia. The two groups were compared in terms of surgery conditions, surgery complication and ambulation time. Results No significant differences were found in surgery time or blood loss between two groups (P>0.05). The postoperative waking time in the mask anesthesia group was significantly shorter than that of the intubation anesthesia group (P<0.05), and ambulation time was significantly shortened (P<0.05). The rates of throat discomfort, hoarseness and gastrointestinal reactions were significantly lower. Conclusions Laryngeal mask anesthesia used in small thoracoscopic surgery for airway management is safe and feasible. Combined with training in respiration and limb function, better analgesia and nursing, it can keep away complications related to intubation anesthesia, shorten hospital stay and accelerate postoperative rehabilitation.

Objective To investigate the clinical efficacy of electrothermal acupuncture in treating ankylosing spondylitis.Method Sixty patients were randomly allocated to treatment and controlgroups, 30 cases each.The treatment group received electrothermal acupuncture and the control group took methotrexate plus sulfasalazine.The extent of chestexpansion, the severity of sacroiliac joint tenderness, the number of tender joints and morning stiffness time were examined,Schober's testscores at different time points were recorded and interleukin-1 (IL-1) and interleukin-6 (IL-6) contents were measured before and after 4 and 8 weeks of treatment.Result In the treatment group, there were statistically significant differences in the extent of chestexpansion, the severity of sacroiliacjoint tenderness, the number of tender joints, morning stiffness time andSchober's testscores after 4 and 8 weeks of treatment compared with before treatment (P<0.05).There were statistically significant pre-/post-treatment differences in IL-1 and IL-6 contents in the two groups (P<0.05). The total efficacy rate was 80.0% in the treatment group and 73.3% in the control group; there was no statistically significant difference between the twogroups(P>0.05). ConclusionElectrothermal acupuncture has a marked therapeutic effect onankylosing spondylitisand is of high safety.The mechanism of electrothermal acupuncture treatment forankylosing spondylitismay be related to its regulating IL-1 and IL-6 levels in the body.

Objective:To investigate the blood lipid status and its variation regularity of a population of teaching staff in order to provide evidence for preventing hyperlipidemia.Method:Lipid indexes such as TC,Triglyceride(TG),LDL-C and HDL-C are inspected of a group of teaching staff over 40 years old in some certain university,and data statistics and analysis are conducted.Conclusion:Main behaviors of male and female teaching staff's hyperlipidemia are high TG and high LDL-C.Special focus should be put on blood lipid's variation level of middle aged males around 40 years old,periodical clinical monitoring should be done for female teaching staff over 50 years old.Medical information instruction on the prevention and control of high blood lipid should be strengthened in order to realize the unity of self control and social control.

Objective To analyze CT morphologic features and pathologic changes of pulmonary sclerosing pneumocytoma (PSP) and to improve preoperative diagnostic accuracy of PSP.Methods The clinical and CT data of 12 cases with PSP (with total 13 lesions)confirmed by surgery and pathology were collected and analyzed retrospectively.All cases performed CT plain scan,9 cases had contrast CT scan.Results 1 1 cases had isolated lesions,and 1 case multiple lesions.The long-axis diameter ranged from 1.10 cm to 8.03 cm, with an average of (3.53±0.78)cm.Of 13 lesions,3 located in left lung (23.1%,1 in the upper lobes,2 in lower lobe),and 10 in right lung (76.9%,2 in upper lobe,2 in the middle lobe and 6 in lower lobe);8 lesions located in the lower lobe (61.5%),and 5 in upper and middle lobe (38.5%).There were center type of 4 lesions (30.8%),and peripheral type of 9 lesions (69.2%);The shapes of 8 lesions wereovoid or similar round (61.5%),irregular type of 1 case (7.7%),shallow lobe of 4 cases (30.8%);Smooth edge of 10 cases (76.9%), burr edge in 3 cases (23.1%).With contrast CT scan,7 cases (53.8%)had vascular welt sign,6 cases (46.2%)had air crescent sign,6 cases (46.2%)had halo sign,and 6 cases (46.2%)had tail sign.3 lesions (23.1%)had scattered spot calcification,and the other lesions had uniform density.The CT value ranged from 28 HU to 47 HU,with the average of 35 HU;Of 9 cases (with 10 lesions)with contrast CT scan,2 lesions had mild enhancement,5 cases had obvious enhancement,and 3 case had non-uniform enhancement.Enhanced CT value was 60-1 10 HU,with the average of 77.2 HU,and with the maximum of 75 HU.Conclusion If the pulmonary nodules or masses in middle-aged females had single round or ovoid shape,with about 3 cm diameters,soft-tissue density,smooth edge,and with obvious enhancement after contrast CT scan,and accompanied by vascular welt sign,air crescent sign,halo sign,or tail sign, the diagnosis of PSP should be considered.

Objective To investigate the neuroprotective effects and mechanisms of 5-aminoimidazole-4-carboxamide ribonucleotide formyltransferase/ IMP cyclohydrolase(AICAR) supplement (AMPK activator) in different stages of neonatal rats sufferring from hypoxia-ischemia encephalopathy ( HIE). Methods Neonatal rat hypoxia-ischemia brain injury model was employed in this study. A total of 160 neonatal rats were distributed into five groups: sham, model control,AICAR30 min, AICAR24 h and AICAR72 h. The neuroprotective effects of AICAR supplement (30 min, 24 h, 72 h post operation) were compared by cresyl violet staining; Expressions of P-AMPK,AMPK in the brain tissue were measured by Western blotting.Foot-faults method was used to evaluate the long-term prognosis of the rats. Results Compared with the sham group, the survival of rats brain in model control group was significantly decreased [(100.0± 0.1)% and (45.3± 6.3)%, P< 0.05]. AICAR had neuroprotective effects when treated at 30 min and 24 h post operation,while the protective effects disappeared when treated later (72 h post operation) (P>0.05). Compared with the sham group, the expression of P-AMPK significantly increased about three times, while ATP level decreased close to the same. Conclusion Early AICAR treatment can protect hypoxia-ischemia brain injury by increasing AMPK-ATP level.

Objective To study the mechanism that glial cell line-derived neurotrophic factor (GDNF)promotes human glio-ma cells proliferation.Methods We divided glioma samples into two groups,including low-grade glioma group and high-grade glio-ma group,while cerebral contusion patients were treated as the control group,12 cases in each group.C6 glioma cell lines were di-vided into three groups,such as GDNF group,BSA(bovine serum albumin)group and control group.CCK-8 (cell counting kit-8) was used to detect the cell proliferation,while Western blot was used to detect the expression of AKT,p-AKT,β-catenin and p-β-catenin in each group.Results Comparing with the control group,the expression levels of AKT,p-AKT,β-catenin and p-β-catenin in glioma group had a significantly increased (P <0.05).Meanwhile,the high-grade gliomas group also had a significant increase in those more than low-grade gliomas group (P <0.05).CCK-8 test showed that the cell proliferation in GDNF group was significant-ly higher than the control group (P <0.05),and the expression levels of p-AKT,β-catenin and p-β-catenin proteins all had a signifi-cant increase (P <0.05).However,the expression level of AKT had no obvious difference.Conclusion GDNF might promote the proliferation of glioma cells by up-regulating the expression of p-AKT,β-catenin and p-β-catenin.
