ObjectiveTo analyze the causes of discomfort occurring in the interventional treatment of diabetic foot, to discuss the individualized nursing measures for improving the patient's comfort and cooperation,and for increasing the successful rate of the interventional procedure.MethodsThe control group included 9 patients who received conventional nursing care.The study group had 13 patients who accepted individualized nursing care and nursing intervention, which was designed according to every patient's individual conditions. ResultsIn the control group, one patient could not endure the surgery to the end because of the long operating time. Another two patients had to take examinations repeatedly because the imaging quality was very poor,which was caused by the body movement due to uncomfortable mechanical stimulation.Urinary retention occurred in one patient.The mean operative time of the control group was 2.8 hour per surgery.The average dosage of contrast medium used was 150 -300 ml per procedure.All the subjects in the study group completed the surgery successfully,the mean operative time was 2.2 hour per surgery and the average dosage of contrast medium used was 100 -200 ml per procedure.Conclusion During the perioperative period of interventional treatment for diabetic foot, the effective individualized nursing care and nursing intervention,the measures to improve patient's comfort and the cooperation,etc. can certainly increase the successful rate,saving the operating time and reducing the contrast dosage.

Objective To investigate the relationship between degree of endometrioma adhesions and clinical feature, surgical treatment and postoperative recurrence. Methods From Jan 2003 to Mar 2008, 662 patients with endometrioma undergoing laparoscopic ovarian endometrioma excision in Peking Union Medical College Hospital were studied retrospectively. All patients were classified into four groups according to the extent of adhesions: 31 cases in none adhesions group, 123 cases in mild adhesions group (filmy thickness, avascular, easily separated adhesions), 310 cases in moderate adhesions group (less than a half of ovary was adjacent to dense thickness adhesions which was difficult to separate, or above a half of ovary were adjacent to filmy thickness adhesions) and 198 cases in severe adhesions group (above a half of ovary was adjacent to dense thickness, well vascularized adhesions which was difficult to separate, and always involved the other pelvic organs, observed angiogenesis). The comparison of degree, characteristics, period of pain, lab test, surgical management and postoperative recurrence was performed among those above groups. In the mean time, risk factors and multinomial logistic regression were analyzed. Results (1)Clinical characteristics: The incidence of patients with dysmenorrhea, dyspareunia, straining feeling in anus, chronic pelvic pain and the level of CA125 (>35 kU/L) was remarkably higher in moderate-to-severe adhesion groups than in none-to-mild adhesions groups (P=0.000, 0.000, 0.001, 0.006 and 0.000, respectively). Infertility rate were significantly higher in severe adhesions group(15.7%,31/198) than none adhesions group(3.2%,1/31), mild adhesions group(11.4%,14/123) and moderate adhesions group(9.7%,30/310, OR=1.728, P<0.05).(2)Operating time and blood loss: Operating time of each groups was as followed: (37±15) min in none adhesions group, (42±19) min in mild adhesions group, (50±20) min in moderate adhesions group and (63±22) min in severe adhesion group. Blood loss was (23±12) ml in none adhesion group, (31±27) ml in mild adhesion group, (40±32) ml in moderate adhesion group and (70±67) ml in severe adhesions group. Thicker adhesions result in longer operation time and more blood loss. (3)Combined with other disease: The ratio of patients who combined with adenomyosis or deeply infiltrating endometriosis in moderate-to-severer adhesion groups was higher than patients in none-to-mild adhesions groups (OR=3.466, P=0.000). (4) Postoperative recurrence: It was categorized into recurrence of pain and cyst. Moderate-to-severe adhesions was related to higher recurrence rate of pain (OR=1.685,P=0.046), but was irrelevant to recurrence of cyst. Conclusion The more extent of endometrioma adhesions was related to severer pelvic pain symptoms, longer operating time and more blood loss. Postoperative pain recurrence rate was observed in moderate-to-severe adhesion group. Extent of adhesions was irrelevant to cyst recurrence.

Objective To study the significance of pain symptoms and physical signs to diagnosis of deeply infiltrating endometriosis (DIE).Methods Totally 500 patients with laparoscopic diagnosis of endometriosis were studied retrospectively and divided into two groups depending on the existance of DIE.The pain symptoms and gynecological physical signs were recorded detail,and the correlation with diagnose of DIE were analyzed.Results (1) The significance of pain symptoms:the sensitivity,specificity,positive predictive value (PPV),negative predictive value (NPV) and OR,95％ CI of each pain symptom were:dysmenorrhae (90.5％,37.2％,59.6％,79.3％,5.66,3.46-9.28),chronic pelvic pain (35.2％,82.6％,67.4％,55.4％,2.58,1.70-3.91),dyspareunia (46.2％,80.6％,70.7％,59.6％,3.56,2.39-5.32),dyschezia (51.0％,73.7％,66.5％,59.5％,2.91,2.00-4.24),respectively.(2) Pelvic physical examination:the sensitivity,specificity,PPV and NPV of each physical sign were:fixed uterine:73.6％,71.2％,79.5％,64.0％; fixed ovarian cyst:94.1％,20.3％,63.3％,70.0％; uterosacral ligaments nodule:47.1％,97.5％,96.6％,54.9％; uterosacral ligaments nodule with tenderness:81.7％,75.0％,83.1％,73.2％; rectovaginal septum nodule:32.2％,100.0％,100.0％,49.4％; rectovaginal septum nodule with tenderness:32.2％,100.0％,100.0％,49.4％; blue nodule in posterior vaginal forni:14.9％,100.0％,100.0％,43.7％.Conclusions In the symptoms,the dysmenorrheal has the highest sensitivity and NPV for the diagnosis.And chronic pelvic pain has the highest specificity,and dysparaunia has the highest PPV for the diagnosis.In pelvic vaginal examination,fixed uterine,fixed ovarian cyst and the nodule on uretosarcal ligment and rectovaginal septum with tenderness,the blue lesion on posterior fornix have the strong significance for DIE.So record the symptom detail and careful digital vaginal examination,especially the vaginal-recto-abdominal examination could improve the diagnosis DIE obviously before procedure.

The present paper proposed a central-driven structure of upper limb rehabilitation robot in order to reduce the volume of the robotic arm in the structure, and also to reduce the influence of motor noise, radiation and other adverse factors on upper limb dysfunction patient. The forward and inverse kinematics equations have been obtained with using the Denavit-Hartenberg (D-H) parameter method. The motion simulation has been done to obtain the angle-time curve of each joint and the position-time curve of handle under setting rehabilitation path by using Solid Works software. Experimental results showed that the rationality with the central-driven structure design had been verified by the fact that the handle could move under setting rehabilitation path. The effectiveness of kinematics equations had been proved, and the error was less than 3° by comparing the angle-time curves obtained from calculation with those from motion simulation.

AIM:To observe the effect of atorvastatin(ATV) on myocardial ischemia-reperfusion injury and the role of inducible nitric oxide synthase (iNOS). METHODS: The rabbits were randomly divided into control group, ATV group, ATV+S-Methylisothiourea sulfate (SMT) group, SMT group. All rabbits were subjected to 40 min ischemia and 240 min reperfusion. The hemodynamic variables, CK-MB, LDH-1 and nitric oxide synthase were detected after reperfusion. RESULTS: LVDP and +dp/dtmax decreased by 24.6% and 35.3% respectively following ischemia-reperfusion. Pre-treated by ATV (10 mg?kg-1?d-1) for three days, LVDP and +dp/dtmax decreased by 21.7% and 41.3%, CK-MB and LDH-1 by 31.4% and 19.1% and iNOS increased to 102.6%. The reduction of LVDP and +dp/dtmax, CK-MB, LDH-1 and iNOS in ATV+SMT group was no statistically significant with those in control group. CONCLUSION: ATV pretreatment protected myocardial ischemia-reperfusion injury by upregulating iNOS.

OBJECTIVE:To study the influencing factors of protocol deviation in drug clinical trial implementation,and pro-vide reference for improving the quality of drug clinical trial. METHODS:Quality verification was conducted for the drug clinical trial projects in the First Affiliated Hospital of Chongqing Medical University during 2010-2016,and protocol deviations in each year were retrospectively studied,classified and analyzed. Category,frequency,international and domestic pilot projects and the differences of protocol deviation after full-time research nurse participating in trail management were explored,and the measures were put forward. RESULTS:27 drug clinical trials were implemented in our hospital during 2010-2016,including 949 cases,176 cases with protocol deviation,accounting for 18.55％. Deviation protocol in drug clinical trial was decreased year by year for 7 years. The categories were mainly incompleteness of observation/records (30.11％),checking omission/broaden the window(28.41％),adverse drug events and improper combined medication (14.20％) and omission in drug management (11.93％). The proportion of protocol deviation with full-time research nurse participated was lower than the projects without full-time research nurse(11.11％ vs. 28.67％,P<0.01),and proportion of deviation protocol in international multi-center project was lower than the domestic projects(6.60％ vs. 28.84％,P<0.01). CONCLUSIONS:It is suggested to pointedly strengthen the weak links of drug clinical trial. For example,clinical trial institutions should establish the clinical trial data retention system,electronic data should be timely backed up in a different places,etc. Besides,clinical trial institutions should equip professional full-time research nurses as much as possible,learn the rigorous scientific experimental design,standard operational procedures and the authenticity of data pro-cessing from the international multi-center clinical trial projects to effectively reduce the incidence of deviation protocol and im-prove the quality of drug clinical trials.
