Abstract: Pneumococcal vaccine plays a key role in preventing diseases such as pneumonia and meningitis caused by Streptococcus pneumoniae (S. pneumoniae). Capsular polysaccharide, C-polysaccharide and phosphorus content are important indicators for quality control of polysaccharide antigens in vaccine development and production. In this study, a quantitative 1H NMR and 31P NMR method based on a single internal standard hexamethylphosphoramide (HMPA) was developed to achieve simultaneous determination of capsular polysaccharide, C-polysaccharide and phosphorus content in 6A, 6B, 18C, 19A, 19F and 23F S. pneumoniae polysaccharide antigens. Using the internal reference comparison method, the effect of solubility of polysaccharide on quantitative 1H NMR determination was investigated. It was found that the determination results of quantitative 1H NMR were affected by the viscosity and concentration of polysaccharide solution. It was found that high viscosity polysaccharides at 3−15 mg/mL and low viscosity polysaccharides at 5−25 mg/mL were the optimal detection solution concentration range. This “one internal standard three quantitative” NMR method has good precision, specificity and accuracy, and provides a valuable new strategy for the quality control of pneumococcal vaccine.

Objective:
To investigate the application and therapeutic effect of external tissue expansion-assisted autologous fat grafting for delayed breast reconstruction.
Methods:
Patients began wearing the BRAVA negative pressure system 8 hours a day for recipient tissue expansion for one month before the fat grafting procedure. After fat grafting, BRAVA was recommended to be worn 8 hours a day from postoperative 48 hours to one month. The interval of each fat grafting procedure was 2.5 to 3.0 months. The procedures were repeated until the completion of breast reconstruction. Water-jet assisted liposuction and subcutaneous release of scars were also performed during surgery.
Results:
From January 2013 to November 2016, 29 patients were followed up for 12 to 58 months, with average of 31.6 months. 28 patients completed the external tissue expansion-assisted autologous fat grafting breast reconstruction. Completion required 1 to 6 procedures, with average of 3.4 procedures. The total initial fat fill volume for each breast was ranged from 200 to 1 000 ml, with average of 583.7 ml. The initial fat fill volume for each breast was ranged from 92.5 to 243.7 ml per operation, with average of 173.8 ml. One patient underwent latissimus dorsi myocutaneous flap breast reconstruction after 3 fat grafting procedures. 8 patients completed the inframammary fold reconstruction, 3 patients underwent breast lift, 1 patient underwent lipofilling augmentation for the contralateral side. Postoperative satisfaction rate was 82.8% in patients and 75.9% in surgeon. Complication statistics: 5 cases of palpable nodules which recognized as fat necrosis (17.2%), one case of nontuberculous mycobacterial infection (3.4%) and one case of locoregional cancer recurrence (3.4%).
Conclusions
External tissue expansion-assisted autologous fat grafting is a minimally invasive procedure for breast reconstruction. Satisfactory results could be obtained for most of the patients who would like to choose fat grafting and have enough fat deposit in other parts of the body.

Objective:
To investigate the satisfaction and well-being of Chinese women with breast deficiency, and to analyze the relevant influencing factors.
Methods:
A cross-sectional study was conducted using a self-designed questionnaire to investigate the women with breast deficiency, visiting the Plastic Surgery Hospital of Chinese Academy of Medical Sciences from November 2013 to August 2018. The BREAST-Q BR (breast reconstruction) pre-operation and post-operation modules were used to assess the quality of life.
Results:
A total of 139 effective questionnaires were collected, including 83 patients before BR surgery and 56 post. There was no difference in quality of life in different ages, marital status, education levels, working status, and causes of breast deficiency. Mean scores of satisfaction with breasts, psychosocial well-being and sexual well-being of patients after breast reconstruction were significantly higher than those of patients without reconstruction (

Objective To investigate the related factors of fat necrosis nodules after autologous fat grafting for breast reconstruction.Methods Different methods of purification,number of operations,and history of breast radiation were analyzed.The relationship between fat graft and necrosis were compared.A total of 48 patients undergoing autologous transplantation for breast reconstruction after radical mastectomy between January 2015 and June 2017 in Chinese Academy of Medical Sciences were retrospectively analyzed,and 51 breasts were used.Results After surgery,9 cases of palpable nodules were found in the breast,including 8 cases in the centrifuge group and 1 case in the sedimentation group.There were 20 cases of multiple hypoechoic nodules in breast ultrasound,including 13 cases in the centrifugation group and 7 cases in the sedimentation group.The incidence of breast nodules in the centrifuge group was 33.33%,and the incidence of fat liquefaction cysts was 54.17%;the incidence of breast nodules in the sedimentation group was 3.7%,and the incidence of fat liquefaction cysts was 25.93%.In this study,there were 4 cases of breast fat filling surgery,18 cases of fat graft for 2 times,23 cases of breast fat filling for 3 times,and 6 cases of fat filling for 4 times;the more time of fat graft surgery,the higher of the fat necrosis incidence.There were 21 cases of breasts with radiotherapy history,30 cases of breast without radiotherapy history,7 cases of nodules after autologous fat transplantation and breast reconstruction in radiotherapy group,2 cases of nodules that could be touched after autologous fat transplantation without breast reconstruction,and 2 cases with radio therapy.The incidence of fat necrosis after fat transplantation breast reconstruction was higher than those without radiotherapy.Conclusions The incidence of fat necrosis after fat-purified with centrifugation autologous grafting for breast reconstruction is higher than that by sedimentation method.The higher rate of fat necrosis is observed after breast reconstruction with autologous fat grafting in radiotherapy than that without radiotherapy.

Objective To investigate the effects of the third-generation mechanical chest compressor on outcomes of cardiopulmonary resuscitation in patients with out-of-hospital cardiac arrest.Methods The patients with out-of-hospital cardiac arrest from October 2015 to September 2017 in the Yuyao peoples' hospital were included and divided randomly into 2 groups:manual chest compression group and mechanical chest compression group.The duration of resuscitation,the rate of restoration of spontaneous circulation (ROSC),4-h survival rate and the rate of survival getting to hospital discharge with favorable neurological status of two groups were analyzed.Results A total of 95 patients with out-of-hospital cardiac arrest were included.The rate of ROSC and 4-h survival was significantly increased in the mechanical chest compression group compared with the manual chest compression group (P<0.05).There was no remarkable difference in the duration of resuscitation and the rate of survival getting to hospital discharge with favorable neurological status between 2 groups.Conclusions The thirdgeneration mechanical chest compressor significantly improves the rate of ROSC and the shout-term survival in patients with out-of-hospital cardiac arrest.
