Objective To evaluate the quality of life status in patients aged 70 years and over following off-pump coronary artery bypass (OPCAB) grafting. Methods Seventy-eight patients with coronary heart disease [mean age (74.6 ± 5.3) years, 66 males, 12 females] were investigated retrospectively. Three questionnaires about the quality of life, including Seattle Angina Questionnaire (SAQ), Nottingham Healthy Profile (Part Ⅰ NHP) and Duke Activity Status Index (DASD, were used to investigate patients before and after OPCAB. Results Prior to OPCAB, there was lower quality of life index in males than in females [SAQ: (65.3±5.1) vs. (69.5±8.1); NHP: (89.4±17.3) vs. (125.2±19.9), P<0.01; DASI: (4. 1±1.1) vs. (4.3± 1.3)]. At the 12th months after OPCABG, there were significant improvements in all patients. The effects were less pronounced in females than in males [SAQ: (83.1 ±5.8) vs. (88.5±4.5), P<0.05; NHP: (84.7± 11.7) vs.(91.4±13.7), P<0.05; DASI: (4.7±1.4) vs. (5.4±1.1)]. Conclusions Our study shows that OPCAB improves quality of life in elderly patients with coronary heart disease. The benefits of OPCAB are even more pronounced in male patients.

Objective:To determine the median effective dose (ED 50) of ciprofol inhibiting responses to insertion of laryngeal mask airway in the patients when combined with alfentanil. Methods:American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients of either sex, aged 40-64 yr, with body mass index of 20-30 kg/m 2, undergoing elective general anesthesia, were enrolled. Midazolam 0.025 mg/kg was intravenously injected for anesthesia induction, the baseline mean arterial pressure and heart rate were recorded 5 min later, and the average value of three times was considered as the baseline value. Ciprofol and alfentanil 10 μg/kg were intravenously injected in sequence, rocuronium 0.6 mg/kg was intravenously injected when BIS value < 60, 2 min later a laryngeal mask airway was placed, and mechanical ventilation was performed. Positive response was defined as increase in the maximum mean arterial blood pressure or heart rate more than or equal to 20% of the baseline value within 3 min after placement of the laryngeal mask airway or as the occurrence of body movement, bucking, frowning, mouth and face twitching, tearing, laryngospasm or the BIS value failing to drop below 60. The study was performed by the Dixon′s up-and-down method. The initial dose of ciprofol was 0.4 mg/kg, and the ratio between the two successive doses was 1.1. If a positive response occurred, the dose was increased in the next patient, otherwise the dose was reduced. The ED 50 and 95% confidence interval of ciprofol inhibiting responses to insertion of laryngeal mask airway were calculated by the probit method. Results:The ED 50(95% confidence interval) of ciprofol inhibiting responses to insertion of laryngeal mask airway was 0.291(0.231-0.318) mg/kg when combined with alfentanil 10 μg/kg. Conclusions:The ED 50 of ciprofol inhibiting responses to insertion of laryngeal mask airway is 0.291 mg/kg in the patients when combined with alfentanil 10 μg/kg.

BACKGROUND:
Syringomyelia is a progressive chronic disease that leads to nerve pain, sensory dissociation, and dyskinesia. Symptoms often do not improve after surgery. Stem cells have been widely explored for the treatment of nervous system diseases due to their immunoregulatory and neural replacement abilities.
METHODS:
In this study, we used a rat model of syringomyelia characterized by focal dilatation of the central canal to explore an effective transplantation scheme and evaluate the effect of mesenchymal stem cells and induced neural stem cells for the treatment of syringomyelia.
RESULTS:
The results showed that cell transplantation could not only promote syrinx shrinkage but also stimulate the proliferation of ependymal cells, and the effect of this result was related to the transplantation location. These reactions appeared only when the cells were transplanted into the cavity. Additionally, we discovered that cell transplantation transformed activated microglia into the M2 phenotype. IGF1-expressing M2 microglia may play a significant role in the repair of nerve pain.
CONCLUSION
Cell transplantation can promote cavity shrinkage and regulate the local inflammatory environment.Moreover, the proliferation of ependymal cells may indicate the activation of endogenous stem cells, which is important for the regeneration and repair of spinal cord injury.

Objective:
To investigate the principles of differential diagnosis of pulmonary infiltrates in cancer patients during the outbreak of novel coronavirus (2019-nCoV) by analyzing one case of lymphoma who presented pulmonary ground-glass opacities (GGO) after courses of chemotherapy.
Methods:
Baseline demographics and clinicopathological data of eligible patients were retrieved from medical records. Information of clinical manifestations, history of epidemiology, lab tests and chest CT scan images of visiting patients from February 13 to February 28 were collected. Literatures about pulmonary infiltrates in cancer patients were searched from databases including PUBMED, EMBASE and CNKI.
Results:
Among the 139 cancer patients underwent chest CT scans before chemotherapy, pulmonary infiltrates were identified in eight patients (5.8%), five of whom were characterized as GGOs in lungs. 2019-nCoV nuclear acid testing was performed in three patients and the results were negative. One case was a 66-year-old man diagnosed as non-Hodgkin lymphoma and underwent CHOP chemotherapy regimen. His chest CT scan image displayed multiple GGOs in lungs and the complete blood count showed decreased lymphocytes. This patient denied any contact with confirmed/suspected cases of 2019-nCoV infection and without fever and other respiratory symptoms. Considering the negative result of nuclear acid testing, this patient was presumptively diagnosed as viral pneumonia and an experiential anti-infection treatment had been prescribed for him.
Conclusions
The 2019 novel coronavirus disease (COVID-19) complicates the clinical scenario of pulmonary infiltrates in cancer patients. The epidemic history, clinical manifestation, CT scan image and lab test should be combined consideration. The 2019-nCoV nuclear acid testing might be applicated in more selected patients. Active anti-infection treatment and surveillance of patient condition should be initiated if infectious disease is considered.
