Objective To explore the effect of ultrasound assisted liposuction in vivo on clinical aesthetic plastic surgery. Methods Ultrasonic lipoplastics combined with swelling liposuction were used in 153 cases of the beauty seekers. Application of rountine tissue swelling technique with the transduction of ultrasound into fatty areas made atipose cells broken and emulsified, and it also easy to move the atipose tissue rich in connective fibres. Results All the patients were satified with the aesthetic effects after the operation. Smoothness and softness of the operated areas with obvious shrinkage of the skin were found with few complications. Conclusion Ultrasound assisted liposuction is an effective and simplified method and deserves to be widely used.

Objective To explore the four criteria,including bedside index for severity in acute pancreatitis(BISAP),Ranson score,modified CT severity index(MCTSI) and acute physiology and chronic health evaluation scoring system Ⅱ (APACHE Ⅱ) in assessment of severity and prognosis of hyperlipidemic acute pancreatitis.Methods A total of 326 patients with hyperlipidemic acute pancreatitis were studied retrospectively from August 2006 to July 2015.The discrepancy of the four criteria in assessment of severity and prognosis of hyperlipidemic acute pancreatitis was compared with chi-square test and receiver operating characteristic curve.Results The incidences of moderately severe acute pancreatitis and severe acute pancreatitis,local complications and mortality of patients with BISAP score ≥3,Ranson score ≥3,APACHE Ⅱ score≥8 and MCTSI score≥4 were significantly higher than BISAP score ＜ 3,Ranson score ＜ 3,APACHE Ⅱ score ＜ 8 and MCTSI ＜ 4 respectively (all P ＜ 0.05).As far as severity was concerned,the sensitivity and AUC of APACHE Ⅱ were 57％ and 0.814,which were higher than the other systems.The second most sensitive criterion was BISAP.In assessment of local complications,the sensitivity and AUC of MCTSI were 68％ and 0.791,which were higher than the other three.The most sensitive criterion to predict mortality was BISAP with sensitivity 89％ and AUC 0.867,which was followed by APACHE Ⅱ.Conclusions All four criteria can be used to determine the severity,local complications and mortality.Generally,BISAP is simple and easy to practice,and better than the other three.

BACKGROUND: The nomination of undifferentiated spondyloarthropathy (USpA) has provided clues for the early diagnosis of spondylitis ankylopoietica and other subsets of SpA, thereby avoiding possible wrong treatments.OBJECTIVE: To investigate the prevalence of SpA in the workers and their adult relatives aged over 16 years old from a factory in Beijing urban district, as well as the results of human major histocompatibility complex (MHC) B27 and X-ray inspection on sacroiliac joint.DESIGN: Systematic sampling investigation.SETTING: Department of Internal Medicine, Chenghai District People's Hospital of Shantou City; Rheumatism Research Institute, Medical College of Shantou University; Department of Internal Medicine, Beijing Chaoyang Hospital.PARTICIPANTS: A survey was conducted among 1982 workers and their adult relatives aged over 16 years from a factory in Beijing urban district between May and October 1999; there were 1,025 males and 957 females.They all volunteered into this study after informed of the experiment.METHODS: All examinees were surveyed door to door with the modified Chinese-International Anti-rheumatic Alliance Rheumatism Questionnaire,those with positive results were subjected to physical examination and those suspicious cases were subjected to MHC-B27 and X-ray examination.MAIN OUTCOME MEASURES: The prevalence of SpA in the workersand their adult relatives aged over 16 years from a factory in Beijing urban district, as well as the results of MHC-B27 and sacroiliac joint X-ray inspection.RESULTS: Totally 1,982 subjects were enrolled in this study and all entered the result analysis. The prevalence of spondyloarthropathy was 1.61%(32/1 982), amongst which the prevalence of ankylopoietic spondylitis,USpA, and psoriastic arthritis was 0.31% (6/1 982), 1.21% (24/1 982),and 0.10% (2/1 982), respectively. No other subsets of SpA were observed. USpA was mainly presented by inflammatory lumbago and asymmetric arthrosteitis [83% (20/24), 62% (15/24)], while rheumatoid factor was negative in all subjects. Meanwhile, MHC-B27 was proved positive in 25% (6/24) subjects with the male-to-female ratio of 1.2:1.CONCLUSION: The prevalence of SpA is 1.61% in Beijing urban area,and SpA mainly consists of ankylopoietic spondylitis and USpA.

Objective:To explore the taste alterations and nutritional status of lung cancer patients during chemotherapy, and analyze the correlation between the two.Methods:From June to December 2021, continuous fixed-point sampling was used to select lung cancer inpatients receiving chemotherapy in the Department of Thoracic Medicine of Beijing Cancer Hospital, Peking University. The patients' taste alterations were evaluated using the Chemotherapy-induced Taste Alteration Scale (CiTAS), and their nutritional status was evaluated using the Nutritional Risk Screening 2002 (NRS 2002) and the Global Leadership Initiative on Malnutrition (GLIM). The patients' weight and calf circumference were also measured. Taste alterations were evaluated on the first day before chemotherapy and the eighth days (T1 to T8) of the first to fourth cycles, respectively, at a total of 8 time points. The nutritional status was evaluated at four time points, including T1, T3, T5, and T7. The correlation between taste alterations and nutritional status was analyzed using generalized estimation equations.Results:A total of 77 patients completed all evaluations. The total CiTAS scores of lung cancer patients from T1 to T8 were (4.21±0.05), (5.52±0.14), (4.67±0.08), (6.05±0.17), (4.84±0.10), (6.45±0.18), (4.97±0.10) and (6.57±0.16), respectively. At T1, T3, T5, and T7, the proportion of patients with positive nutritional risk was 10.4% (8/77), 22.1% (17/77), 26.0% (20/77) and 29.9% (23/77), respectively, and the body weight was (67.08±1.07), (66.46±1.09), (66.12±1.09), (65.88±1.09) kg, and the calf circumference was (35.00±2.31), (34.71±2.41), (34.49±2.45), (34.38±2.47) cm and the number of patients with malnutrition was 1 (1.3%), 6 (7.8%), 10 (11.3%) and 11 (11.3%), respectively. The total score of CiTAS was positively correlated with NRS 2002 score, malnutrition ratio, and weight loss, while negatively correlated with calf circumference, with statistically significant differences ( P<0.05) . Conclusions:Patients with lung cancer undergoing chemotherapy have significant taste alterations, which worsen after each cycle of chemotherapy and recover before the next cycle of chemotherapy, but cannot return to baseline levels. The nutritional status of lung cancer patients is deteriorating, with an increasing proportion of patients at nutritional risk and malnutrition, as well as a continuous decline in weight and calf circumference. Taste alterations affect the nutritional status of patients. It is suggested that attention should be paid to the management of taste alterations and nutritional intervention during chemotherapy to improve the nutritional status of patients.
