Objective:To explore the effect of getting out of bed activity 6 hours after silicone breast augmentation surgery on the comfort of patients.Methods:From May 2019 to August 2020, 84 female patients aged 20-37 (28.34±6.27) years who underwent silicone breast augmentation surgery at the Department of Plastic Surgery and Cosmetology at the Second People′s Hospital of Guangdong Province were randomly divided into a control group and an observation group, with 42 patients in each group, using a random number table method. The control group got out of bed 24 hours after surgery, while the observation group got out of bed 6 hours after surgery. The chest drainage and fixation patency, comfort, silicone prosthesis displacement, and incision bleeding rate between the two groups of patients were compared 24 hours after surgery.Results:The extraction time of the thoracic drainage tube in the observation group was (82.64±11.78 hours), which was shorter than that in the control group (90.67±12.44 hours), and the difference was statistically significant ( t=5.369, P<0.01). The comfort scores of the observation group patients at 6 hours after surgery (95.07±4.14) and 24 hours after surgery (97.52±4.07) were higher than those of the control group at 6 hours (91.14±4.03) and 24 hours (94.19±3.93), and the difference was statistically significant ( t=4.413, 3.832, both P<0.01); 7 days after surgery, there were 2 cases of silicone prosthesis displacement in the observation group, with an incidence rate of 4.76% (2/42); there were 2 cases of silicone prosthesis displacement in the control group, with an incidence rate of 4.76% (2/42); there were 6 cases of incision bleeding, with an incidence rate of 14.29% (6/42); there were 5 cases of incision bleeding in the control group, with an incidence rate of 11.90% (5/42). There was no statistically significant difference in the incidence of silicone implant displacement and incision bleeding between the two groups (χ 2=0.21, 0.10, P>0.05). Conclusions:Getting out of bed and moving around 6 hours after silicone breast augmentation surgery can help improve the patient′s physical comfort, ensure smooth fixation of the chest drainage tube, and do not increase the occurrence of incision bleeding in patients.

In view of the recent advancements in the standardized neurology residency training in China, standardized neurology fellowship training has become a crucial next step for China′s graduate medical education. The design of the fellowship and development of relevant norms and standards to ensure quality training constitute key areas in need of further consideration. The United States has established a standardized neurology fellowship training for nearly 30 years and has been successful in ensuring high quality physician training. Currently there are 9 accreditation council for graduate medical education (ACGME) accredited neurology fellowship programs in the USA, including clinical neurophysiology, pain medicine, neurodevelopmental disabilities, vascular neurology, neuromuscular medicine, sleep medicine, endovascular surgical neuroradiology, epilepsy and brain injury medicine. Among them, the number of fellowship training programs in vascular neurology, clinical neurophysiology, and epilepsy are relatively stable or show continuous growth, while neurodevelopmental disabilities and brain injury medicine remain stagnant or even retrogressive. It indicates that design of the neurology fellowship training calls for full weight of a wide array of factors, taking into account the number of subspecialty patients, clinical applications, prospects for future development of the subspecialties, and lessons learned from the United States. We can start with ACGME accredited steady growth fellowship programs and then add others in the future accordingly.

Objective To explore and improve the feasibility and prognostic value of barium radiography and computed tomography (CT)-based evaluation criteria in evaluation of the short-term efficacy of radiotherapy for esophageal cancer,and to provide a basis for clinical application.Methods The short-term treatment outcomes of 529 patients with esophageal carcinoma receiving three-dimensional radiotherapy from 2004 to 2015 were evaluated by the 2013 version of barium radiography and CT-based evaluation criteria.The local control (LC) and survival rates were calculated using the Kaplan-Meier method.The log-rank test was used for data analysis and univariate prognostic analysis.The agreement between two evaluation criteria was measured by the Kappa coefficient.Results According to the results of the survival analysis in all the patients using the evaluation criteria for short-term treatment outcomes,the 3-,5-,7-,and 9-year LC rates were 78.6％,69.8％,69.8％,and 63.4％ in the complete response (CR) group (n=52),and 56.4％,47.9％,46.2％,and 42.4％ in the partial response (PR) group (n=409),respectively;the 3-,5-,7-,and 9-year overall survival (OS) rates were 62.7％,49.1％,39.8％,and 39.8％ in the CR group,and 29.5％,21.6％,20.6％,and 19.5％ in the PR group,respectively;the median OS time was 50,17,and 5 months in the CR group,PR group,and non-response group (n=12),respectively (P=0.000).According to CT measurements,the short diameter of residual metastatic lymph node after radiotherapy was between 0.37-3.40 cm (median value=0.82 em).All patients were divided into groups based on the short diameter of residual metastatic lymph node after radiotherapy with a gradient of 0.5 cm.Patients with short diameters of residual metastatic lymph node of ≤ 1.00 cm had a significantly higher OS rate than those with short diameters of residual metastatic lymph node of＞ 1.00 cm (P =0.000).The lymph node volume of 1.00 cm3 in the original criteria was replaced by the short diameter of residual metastatic lymph node of 1.00 cm after radiotherapy and treatment outcomes were re-evaluated using the new criteria.The CR group still had significantly higher LC and OS rates than the PR group (P=0.000).There was a good agreement between the two evaluation criteria (Kappa =0.863).Conclusions The barium radiography and CT-based evaluation criteria for short-term treatment outcomes can accurately evaluate the short-term outcomes and predict prognosis in patients with esophageal carcinoma.Replacing the volume in the original criteria with the short diameter of residual metastatic lymph node after radiotherapy achieves similar results in prognostic prediction.

This paper aimed at studying the physical and chemical properties, general examination and contents of someeffective components of Erratum Mongolia, and to provide scientific basis for the establishment of the quality standard ofvenerates Mongolia. The physical and chemical properties of venerates were identified by microscope and thin layerchromatography, and the general examination of venerates was studied with reference to the appendix of the 2010 editionof People's Republic of China Pharmacopoeia, and the main characteristic components and the active components inErratum were analyzed by HPLC. The content was analyzed and compared. The characters and microscopic identificationconfirmed that all the 7 batches of samples were venerates. The TLC identification was used as the control product ofhermitage, Erratum and restorative. The test products showed the same color spots in the corresponding position of thecontrol products. The spots were clear and the separation degree was good; the water and extracts of the different batch ofvenerates were examined by general terms. The content of ash in the Erratum collected from different regions was notsignificantly different (5.74-6.98％) . The content of the main active ingredients (hermitage) in Erratum from differentareas of the same plant is compared for the first time. The method is simple and reproducible. It provides a scientificbasis for improving the quality standard of Erratum Mongolia, the safe and rational application and the furtherdevelopment and production.

OBJECTIVETo establish a systematic method for isolation and identification of aerobic and facultative anaerobic bacteria in the oral cavity.

METHODSSamples of the saliva, dental plaque and periapical granulation tissue were collected from 20 subjects with healthy oral condition and from 8 patients with different oral diseases. The bacteria in the samples were identified by morphological identification, VITEK automatic microorganism identification and 16s rRNA gene sequencing.

RESULTSVITEK automatic microorganism identification and 16s rRNA gene sequencing showed an agreement rate of 22.39% in identifying the bacteria in the samples. We identified altogether 63 bacterial genus (175 species), among which Streptococcus, Actinomyces and Staphylococcus were the most common bacterial genus, and Streptococcus anginosus, Actinomyces oris, Streptococcus mutans and Streptococcus mitis were the most common species. Streptococcus anginosus was commonly found in patients with chronic periapical periodontitis. Streptococcus intermedius and Staphylococcus aureus were common in patients with radiation caries, and in patients with rampant caries, Streptococcus mutans was found at considerably higher rate than other species.

CONCLUSIONAerobic and facultative anaerobic bacteria are commonly found in the oral cavity, and most of them are gram-positive. 16s rRNA gene sequencing is more accurate than VITEK automatic microorganism identification in identifying the bacteria.
