AIMTo investigate the effects of mild and moderate hypoxia on human cognitive performance.

METHODSEighteen healthy young male volunteers performed a set of tests of human ergonomics at sea level (300 m in Xi'an) and simulated high altitude of 2 800 m, 3 600 m and 4 400 m for 1 h in hypobaric chamber, respectively.

RESULTSThe performance of continuous recognition memory tests compared with the controls' was deteriorated significantly (P < 0.01) after exposure to 2 800 m for 1 h. After exposure to 3 600 m for 1 h, in all test, the reaction time was much longer, the accurate rates were lower and the performance was worse than that of control (P < 0.05). All the parameters were deteriorated with the increment of altitude and the performance of all tests were much worse at 4 300 m for 1 h (P < 0.01).

CONCLUSIONDifferent parameters of human cognitive performance may have different susceptible thresholds to hypoxia according to the results from our studies. The cognitive performance after exposure to 3 600 m for 1 h was not sufficiently effective for the demands of human ergonomics due to its significant deteriorating changes. However, the performance can be effectively restored after exposure to enough oxygen supply for 1 h.

BACKGROUND:The treatment of acute myocardial infarction (AMI) is thought to restore antegrade blood flow in the infarct-related artery (IRA) and minimize ischemic damage to the myocardium as soon as possible. The present study aimed to identify possible clinical predictors for no-reflow in patients with AMI after primary percutaneous coronary intervention (PCI). METHODS:A total of 312 consecutive patients with AMI who had been treated from January 2008 to December 2010 at the Cardiology Department of East Hospital, Tongji University School of Medicine were enrolled in this study. Inclusion criteria were:(i) patients underwent successfully primary PCI within 12 hours after the appearance of symptoms; or (ii) patients with ischemic chest pain for more than 12 hours after a successful primary PCI within 24 hours after appearance of symptoms. Exculsion criteria were:(i) coronary artery spasm; (ii) diameter stenosis of the culprit lesion was ≤50％ and coronary blood flow was normal; (iii) patients with severe left main coronary or multivessel disease, who had to require emergency revascularization. According to thrombolysis in myocardial infarction (TIMI), the patients were divided into a reflow group and a no-reflow group. The clinical data, angiography findings and surgical data were compared between the two groups. Univariate and multivariate logistic regressions were used to determine the predictors for no-reflow. RESULTS:Fifty-four (17.3％) of the patients developed NR phenomenon after primary PCI. Univariate analysis showed that age, time from onset to reperfusion, systolic blood pressure (SBP) on admission, Killip class of myocardial infarction, intra-aortic balloon pump (IABP) use before primary PCI, TIMI flow grade before primary PCI, type of occlusion, thrombus burden on baseline angiography, target lesion length, reference luminal diameter and method of reperfusion were correlated with no-reflow (P<0.05 for all). Multiple logistic regression analysis identified that age >65 years [OR=1.470, 95％ confidence interval (CI) 1.460–1.490,P=0.007], long time from onset to reperfusion >6 hours (OR=1.270, 95％CI 1.160–1.400,P=0.001), low SBP on admission <100 mmHg (OR=1.910, 95％CI 1.018–3.896,P=0.004), IABP use before PCI (OR= 1.949, 95％CI 1.168–3.253, P=0.011), low (≤1) TIMI flow grade before primary PCI (OR=1.100, 95％CI 1.080–1.250,P<0.001), high thrombus burden (OR=1.600, 95％CI 1.470–2.760,P=0.030), and long target lesion (OR=1.948, 95％CI 1.908–1.990,P=0.019) on angiography were independent predictors of no-reflow. CONCLUSION:The occurrence of no-reflow after primary PCI for acute myocardial infarction can predict clinical, angiographic and procedural features.

OBJECTIVETo summarize the experience with surgical treatment of constrictive pericarditis.

METHODSA retrospective analysis of the post-operative clinical data was conducted in 128 surgical patients with chronic constrictive pericarditis.

RESULTSTwo early postoperative death occurred in this group due to severe low cardiac output syndrome, with the mortality rate of 1.57%. The postoperative complications included low cardiac output syndrome (13.2%), arrhythmia (7.02%), acute renal insufficiency (3.9%), respiratory insufficiency (3.1%), wound infection (2.3%), postoperative chest bleeding (1.6%) and cerebral infarction (0.78%). Relapse occurred in one case because of incomplete pericardial resection.

CONCLUSIONSConstrictive pericarditis should be confirmed as soon as possible with actively surgery, and the extent of pericardial resection should be decided according to the individual conditions. Complete untethering of the diseased pericardium should be performed with active prevention of postoperative complications.

OBJECTIVETo investigate the correlation between expression of A-kinase anchoring protein 95 (AKAP95) and protein expression of cyclin E1 and cyclin D1 in lung cancer tissue.

METHODSFifty-one cases of lung cancer were included in the study. The protein expression of AKAP95, cyclin E1, and cyclin D1 were measured by immunohistochemistry.

RESULTSThe protein expression of cyclin E1 in lung cancer tissues was significantly higher than that in para-cancerous tissues (positive rate: 75.56%vs 20%, P < 0.01); its expression showed no relationship with histopathological type, lymph node metastasis, and cellular differentiation (P > 0.05). The protein expression of cyclin D1 in lung cancer tissues was higher than that in para-cancerous tissues (positive rate: 69.39% vs 14.29%); its expression showed a significant relationship with histopathological type (P < 0.05). The expression of AKAP95 was correlated with the protein expression of cyclin E1 and cyclin D1 in lung cancer tissues (P < 0.01).

CONCLUSIONCyclin E1 and cyclin D1 are highly expressed in lung cancer tissue, suggesting that they play an important role in the development and progression of lung cancer. The protein expression of cyclin E1 has no relationship with cellular differentiation, lymph node metastasis, and histopathological type of lung cancer, and the protein expression of cyclin D1 has a significant relationship with histopathological type. The expression of AKAP95 is correlated with the protein expression of cyclin E1 and cyclin D1 in lung cancer tissue.

OBJECTIVETo investigate the surgical options and clinical effects of delayed osteoporotic vertebral collapse.

METHODSFrom May 2010 to October 2014, 19 patients (20 vertebrae) with delayed osteoporotic vertebral collapse(Kümmell's disease) were enrolled in this study. There were 7 males and 12 females, aged from 65 to 87 years old with a mean of (73.5±5.62) years. According to Li staging system of Kümmell's disease, 3 cases were stage II, 13 cases (14 vertebrae) were stage III without spinal cord injury, 3 cases were stage III with spinal cord injury. Patients were respectively treated with percutaneous vertebroplasty(PVP) or percutaneous kyphoplasty(PKP) on the basis of the degree of postural reduction during operation. Injected cement volume, cement leakage, vertebral height restoration and local kyphotic reduction were observed. Visual analogue scale (VAS) and Oswestry Disability Index(ODI) were respectively used to assess the pain and function before and after operation. Frankel grade were used to evaluate neurological status.

RESULTSSeven vertebrae with satisfactory postural reduction were treated with PVP, 13 vertebrae with unsatisfactory postural reduction were treated with PKP, 3 patients with spinal cord injury were treated with decompression and posterior short segment fixation at the same time. All patients were followed up from 10 to 48 months with an average of 21.2 months. Cement leakage occurred in 4 cases with no symptom, 1 cases in PVP group and 3 cases in PKP group, there was no significant difference between two groups(=0.561). The priming volume of cement was (6.40±0.94) ml in PVP group and (5.46±1.09) ml in PKP group (>0.05). Three days after operation vs preoperation, the vertebral height restoration and kyphotic improvement was(31.71±11.35)%, (9.79±4.64)° in PVP group and (24.77±8.51)%, (8.15±2.97)° in PKP. There was no significant difference between two groups(>0.05). Three days after operation, VAS of low back pain and ODI in all patients were improved than preoperative data(<0.05), but there was no significant difference between two groups or between postoperative at 3 d and final follow up(>0.05). Nerve function of 3 patients underwent decompression and fixation from Frankel D to E.

CONCLUSIONSAccording to Li staging system and the degree of introperative postural reduction, individualized surgical treatment for Kümmell's disease can obtain good clinical results. Bad postural reduction during operation maybe a risk factor of cement leakage.

OBJECTIVETo analyze the efficacy and quality of life and safety for paclitaxel and carboplatin (TC) and TC combined with endostar in the treatment of advanced non-small cell lung cancer (NSCLC).

METHODSThis is a prospective, multicenter, randomized, double-blind, placebo-controlled clinical study. A total of 126 cases of untreated advanced NSCLC were enrolled in this study. There were 63 patients in the TC control arm and TC combined endostar arm, respectively. All enrolled patients were continuously followed-up for disease progression and death.

RESULTSThe objective response rate (ORR) of TC combined with endostar arm was 39.3%, and that of TC control arm was 23.0%, P = 0.078. The progression-free survival rates for TC combined with endostar arm and TC control arm were 78.3% and 58.8%, respectively, in 24 weeks (P = 0.017). The hazard ratio for the risk of disease progression was 0.35 (95%CI 0.13 to 0.90, P = 0.030). The median time to progression (TTP) of the TC combined with endostar arm was 7.1 months and TC arm 6.3 months (P > 0.05). The follow-up results showed that the median survival time (mOS) of the TC + Endostar arm was 17.6 months; (95%CI 13.4 to 21.7 months), and the TC + placebo arm 15.8 months (95%CI 9.4 to 22.9 months) (P > 0.05). The quality of life scores (LCSS patient scale) after treatment of the TC combined with endostar arm was improved, and that of the TC group was improved after completion of two cycles and three cycles of treatment. The quality of life scores compared with baseline after the completion of one cycle treatment was significantly improved for both the TC combined with endostar arm (P = 0.028 and), and TC arm (P = 0.036). It Indicated that TC combined with endostar treatment improved the patient's quality of life in the early treatment. The difference of adverse and serious adverse event rates between the two groups was not significant (P > 0.05).

CONCLUSIONSCompared with TC alone treatmrnt, TC combined with endostar treatment can reduce the risk of disease progression at early time (24 weeks), increase the ORR, and can be used as first-line treatment for advanced NSCLC. The TC combined with endostar treatment has good safety and tolerability, improves the quality of life, and not increases serious adverse effects and toxicity for patients with advanced NSCLC.

Objective:To investigate the current situation of medical social worker supervision in Shanghai, for reference to promote the high-quality development of medical social work.Methods:From June to July 2022, a questionnaire survey was conducted on the in-service medical social workers in all medical institutions with medical social work departments or posts in Shanghai. The questionnaire mainly included demographic information, current status of supervision implementation, and effectiveness of supervision. The data were analyzed descriptively with t test for comparison between groups and the Pearson test was for correlation analysis. Results:A total of 99 medical social workers were included in this study, 65 had received supervision, and medical institutions where 58 people located had established the supervision system. The average scores of actual and expected supervisory support received by medical social workers were 3.71 and 4.20 respectively, and the mean burnout level score was 32.91. The effect of establishing a supervision institutions on burnout was statistically significant ( P<0.05) and actual access to supervision support was negatively associated with burnout ( P<0.05). Conclusions:The overall situation of medical social work supervision in Shanghai was positive, but the demand for supervision was not fully satisfied; Supervision had a positive impact on reducing the burnout level. It is suggested that medical social work should further strengthen the cultivation of supervisory talents, promote the construction of supervisory systems, and improve the quality of supervision.
