Objective:To understand the incidence of sleep disorder in human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) patients before antiviral therapy, and to explore its risk factors.Methods:200 newly treated HIV/AIDS patients who visited the Eighth Affiliated City Hospital of Guangzhou Medical University from January to June 2016 were randomly selected. According to the Pittsburgh Sleep Quality Index (PSQI), they were divided into a good sleep group and a Sleep disorder group; The influencing factors of sleep disorder in HIV/AIDS patients were analyzed by univariate analysis and multivariate logistic regression.Results:The incidence of Sleep disorder in 200 HIV/AIDS patients before antiviral therapy was 22.5%(45/200); CD4 + T cell count was (414.13±202.16)/μl; 29%(58/200) of patients had CD4 + T cell counts<200/μl. There were significant differences in CD4 + T cell count and the proportion of patients with syphilis infection, comorbidity anxiety and comorbidity depression between the good sleep group and the Sleep disorder group (all P<0.05). Multivariate logistic regression analysis showed that syphilis infection ( OR=4.606; 95% CI: 1.973-10.752; P<0.001), comorbidity anxiety ( OR=2.496; 95% CI: 1.086-5.737; P=0.031) and comorbidity depression ( OR=2.087; 95% CI: 0.915-4.760; P=0.040) were risk factors for sleep disorder in HIV/AIDS patients before antiviral treatment. Conclusions:The incidence of Sleep disorder in HIV/AIDS patients before antiviral therapy in Guangzhou is high, especially in patients with syphilis infection, comorbidity anxiety and comorbidity depression. The sleep disorder of HIV/AIDS patients should be assessed and detected early, and multiple interventions should be taken to improve sleep quality.

To investigate cerebral autoregulation(CA)in patients with severe unilateral carotid artery stenosis by near infrared spectroscopy. Thirty patients who underwent general anesthesia in our hospital from January 2015 to February 2017 were enrolled in this study.The stenosis group included 15 patients with severe unilateral internal carotid artery stenosis,and the control group included 15 patients without carotid artery stenosis.Both groups were matched in sex and age.Cerebral tissue oxygenation index(TOI)and mean arterial pressure were recorded continuously under stable general anesthesia.The Pearson correlation coefficient()was calculated to judge the CA status. TOI was not significantly different between the stenosis side and the non-stenosis side in the stenosis group(66.52±6.50 65.23±4.50;=0.93, =0.368)or between the stenosis side in the stenosis group and the stenosis side in the control group(66.52±6.50 64.22±3.87;=1.18, =0.248).The values of stenosis side and non-stenosis side in the stenosis group were 0.36±0.12 and 0.17±0.11,respectively,and the values of the stenosis side in the stenosis group and the stenosis side of the control group were 0.36±0.12 and 0.13±0.08,respectively.In the stenosis group,5 patients had transient ischemic attack and 2 patients had a history of stroke within 3 months before operation.When an value of 0.342 was used as the judgment point of CA abnormality,the sensitivity and specificity were 0.625 and 0.909,respectively. Within the range of normal blood pressure fluctuation,cerebral blood flow is linked to blood pressure at the stenosis side in patients with severe unilateral carotid artery stenosis.

Objective To explore relations between pseudo vascular invasion (PVI) and laparoscopic operation in patients with stage Ⅰa endometrial carcinoma. Methods Details of stage Ⅰa endometrial carcinoma patients′ clinical information and pathological sections who received operation treatment between January 2008 and October 2015 were obtained from the Dalian Maternal and Child Health Hospital. There were 515 cases entrolled into this study, including 332 (64.5%) cases performed surgery by laparoscopy and 183 (35.5%) cases undergone abdominal surgery. The vascular invasion rate and the microscopic manifestations of PVI in two groups were retrospectively compared and analyzed. The follow-up period ended February 2017, the adjuvant treatment and prognosis of patients with lympho-vascular space invasion (LVSI) and PVI were analysed. Results (1) Seventy-five of 515 cases with stage Ⅰa endometrial carcinoma, there were seven-five cases found with tumor cells in lympho-vascular space, including 52 cases of LVSI and 25 cases of PVI (2 cases of both). The incidence of cancer emboli in lympho-vascular space and LVSI in laparoscopic group and laparotomy group were respectively 15.4%(51/332) vs 13.1%(24/183) and 9.6%(32/332) vs 10.9%(20/183), there were no significant differences (all P>0.05). But the rate of PVI between the two group was significantly different [6.3% (21/332) vs 2.2%(4/183), P=0.036], laparoscopic group was higher than that in laparotomy group. (2) Of 332 cases in laparoscopic group, 21 cases was found PVI, containing 8 cases showed tumor tissue with mesenchyme or papillary structures located in large thick wall vessels of the outer lateral myometrium, 13 cases showed the tumor tissue was away from the vessel wall. Among 183 cases in laparotomy group, 3 cases with PVI which the tumor tissue was away from the vessel wall, and 1 with interstitial tissue. (3) During the follow-up period, 7 of 75 cases (both LVSI and PVI) were lost, and 66 cases were relapse-free survival, 2 cases recurred at fifth months and died respectively at 7, 20 months after the operation. This 2 cases were both PVI of laparoscopic group, and the pathological type was endometrioid adenocarcinoma grade 3, and adjuvant treatment was not accepted after the operation. The relapse-free survival with LVSI was 49 months and 46 months for cases with PVI. Conclusions Laparoscopic operation could increase PVI in patients with stageⅠa endometrial carcinoma, while does not increase LVSI. It is not yet possible to demonstrate that PVI affects the prognosis of patients.

It’s still controversial whether there is specificity of acupoints, because numerous studies showed that stimulation to acupoints and sham acupoints produced parallel clinical efficacies. For example, acupoint specificity was not detected when Visual Analogue Scale was adopted to evaluate pain, while hemodynamic and neuroimaging studies suggested the existence of acupoint specificity. This article reviewed and summarized relevant studies that supported or didn’t support acupoint specificity. Further researches are required to prove the existence of specificity of acupoints.

Objective To evaluate the imaging performance and characteristics of peripheral primitive neuroectodermal tumors (pPNET), in order to raise awareness of the disease and the diagnostic accuracy. Methods Thirteen patients with pPNET who confirmed by puncture or pathology were enrolled in this study. The CT and MRI features were retrospectively analyzed. Four patients received simple routine CT examination, and 9 patients had MRI examination based on X-ray, CT examination. Results The part of body involved was more widely.Two patients occurred in the sinuses, 1 patient in the chest wall, 1 patient in the lung, and 3 patients in the abdominal and pelvic(1 patient involved the pelvic floor through the pelvic wall lesions to basins), 1 patient in the spine, and 5 patients located in the extremities. The characteristics of pPNET by CT and MRI in soft tissue of 8 patients showed single large soft tissue mass, and the biggest was 11.2 cm × 10.6 cm. In bonds and joints of 5 patients, CT and MRI showed wide range of soft tissue mass, mixed internal signal/density with obviously uneven enhancement, significant bone destruction and dissolvable osseous changes, and no obvious tumor bone and calcification. Conclusions Each site has its relative imaging characteristics of pPNET. CT and MRI can show lesions involving the scope, internal structure, with or without adjacent tissue invasion and metastasis, and provide guidance for clinical treatment and selecting treatment regimen. But in the end, it depends on the diagnosis of pathological and immunohistochemical examination.

Objective To compare and observe the effect of GASMAN software computer aided and traditional teaching method in the teaching of inhalation anesthesia. Methods 48 members of interns who need to enter the inhalation anesthesia department to study the theory of inhalation anesthesia were ran-domly divided into either GASMAN software group or traditional group with 24 people in each group, using the above two methods to carry on the study of inhalation anesthesia. After the end of the teaching course, the study effect and the satisfaction degree of the two groups of students were investigated by the written exam and questionnaire. SPSS 11.5 was used for statistical analysis, using±s to express measurement data. The results of the examination were compared with the independent sample t test, and the satisfaction survey feedback was compared with chi square test, The difference was statistically significant (P<0.05 ). Result The mean score of GASMAN software group (95.4 ±2.7) was significantly higher than that of tra-ditional group (85.0 ±3.5) (t=11.5,P=0.000). Satisfaction survey results showed that GASMAN computer assisted instruction software learning was easier for students to accept, and there were significant difference between two groups (P=0.001). Conclusion Teaching mode of GASMAN software is a good learning technique of inhalation anesthesia, which is worthy of promotion.
