Objective:To explore the accuracy of a self-made color chart to calculate the amount of blood in the liposuction fluid of patients undergoing liposuction surgery.Methods:A retrospective study was conducted on 60 female patients with a median age of 33 (20-50) years who underwent liposuction surgery at Baiyu Medical Beauty Hospital in Milan, Sichuan from December 2022 to December 2023. The self-made color chart consisted of continuous color photos of liposuction bottles contained different amounts of blood, included continuous color charts with fat to water ratios of 3∶1, 2∶1 and 1∶1. The above chart was used to detect the liposuction solution in 60 clinical liposuction patients and to calculate the blood content. At the same time, the above specimens underwent laboratory testing for red blood cell counting. The differences and correlations were compared between two methods for detecting the amount of blood in liposuction solution.Results:The results showed that the blood content of the liposuction solution was (44.3±15.2), (46.9±20.6), (42.9±19.2) ml based on the color chart with a ratio of 3∶1, 2∶1 and 1∶1, respectively. The red blood cell count laboratory test results were (53.6±15.3), (55.2±20.7), (53.5±18.1) ml, respectively, and the differences were statistically significant (all P<0.05). The results of the two methods showed a linear positive correlation ( Y=1.1 X+5.6, R2=0.989, P<0.01). Conclusion:A self-made color chart can be used to quickly and accurately calculate the blood content in liposuction solution.

Livestock husbandry is vital to economy of the Tarim Basin, Xinjiang Autonomous Region, China. However, there have been few surveys of the distribution of ixodid ticks (Acari: Ixodidae) and tick-borne pathogens affecting domestic animals at these locations. In this study, 3,916 adult ixodid ticks infesting domestic animals were collected from 23 sampling sites during 2012-2016. Ticks were identified to species based on morphology, and the identification was confirmed based on mitochondrial 16S and 12S rRNA sequences. Ten tick species belonging to 4 genera were identified, including Rhipicephalus turanicus, Hyalomma anatolicum, Rh. bursa, H. asiaticum asiaticum, and Rh. sanguineus. DNA sequences of Rickettsia spp. (spotted fever group) and Anaplasma spp. were detected in these ticks. Phylogenetic analyses revealed possible existence of undescribed Babesia spp. and Borrelia spp. This study illustrates potential threat to domestic animals and humans from tick-borne pathogens.

This paper explored the feasibility of using ultrasonic Nakagami statistic parameter imaging to evaluate the thermal lesion induced by microwave ablation (MWA) in porcine models. In this paper, thermal lesions were induced in livers and kidneys in 5 swines using a clinical MWA system. During this treatment progress, ultrasonic radiofrequency (RF) data were collected. The dynamic changes of Nakagami parameter in the thermal lesion were calculated, and the ultrasonic B-mode images and Nakagami images were reconstructed simultaneously. The contrast-to-noise ratio (CNR) between the thermal lesion and the surrounding normal tissue was calculated over the MWA procedure. After MWA, a bright hyperechoic region appeared in the ultrasonic Nakagami image as an indicator of the thermal lesion and this bright spot enlarged with lesion development during MWA exposure. The mean value of Nakagami parameter in the liver and kidney increased from 0.78 and 0.79 before treatment to 0.91 and 0.92 after treatment, respectively. During MWA exposure, the mean values of CNR calculated from the Nakagami parameter increased from 0.49 to 1.13 in the porcine liver and increased from 0.51 to 0.85 in the kidney, which were both higher than those calculated from the B-mode images. This study on porcine models suggested that the ultrasonic Nakagami imaging may provide an alternative modality for monitoring MWA treatment.

ObjectiveTo recognize the normal CT appearances of adult pterygoid hamulus and increase the ability to recognize pterygoid hamulus abnormalities.Methods The pterygoid hamulus of 108 normal adults ( male:53 cases,female,55 cases) were studied with MIP and VR reconstructive images by 64-slice spiral CT in order to observe its normal shape,to measure its length,diameter,vertical height,horizontal width,abduct angle in coronal position and post-abducent angle in anteroposterior position.The differences between genders,two sides and age groups were compared,respectively.ResultsThe normal pterygoid hamulus had a wide basal body and a pillar caudomedial part with round or intumescentia extreme.In coronal position,the distal end towards outer direction in 214 sides and 2 sides in inner direction. In anteroposterior position,the distal end towards posterior direction in 190 sides and anterior direction in 26 sides.The pterygoid hamulus length,vertical height,and horizontal width of adult males were (8.18 ± 0.94) mm,(7.23 ±0.92) mm,(4.27 ±0.81 ) mm,respectively.They were larger than the adult females (7.31 ± 1.01) mm,(6.26 ±0.90) mm,(3.97 ±0.82) mm,and the difference was statistically significant (t values were 6.56,7.86,2.72 respectively,P ＜ 0.05).The pterygoid hamulus vertical height of age group over 60 years old (7.13 ± 1.35) mm exceeded the age groups of 18-39 (6.55 ±0.86) mm.The difference was statistically significant ( F =4.95,P ＜ 0.05 ).Conclusions64-slice spiral CT could display the shape,length and angle of pterygoid hamulus in full. It could help to recognize correlated pterygoid hamulus diseases.

Objective To study the Hainan Utstein templates used for cardiac arrest and resuscitation registries to evaluate the epidemiological characteristics and outcomes of the patients with CPR by multi-center study. Methodsccording to the Utstein templates for cardiac arrest and CPR set by International Liaison Committee on resuscitation in 2004, a Hainan Utstein CPR registry chart was designed and a prospective descriptive study was carried out to evaluate the epidemiological characteristics, impact factors and outcomes of the patients with resuscitation attempt in emergency departments of thirteen hospitals in Hainan Island between January 2007 and December 2010.Results Of 1125 patients with cardiac arrest, male accounted for 73. 8％ and female was 26. 2％. The mean ( ± S. D) age of the cardiac arrest patients was 53.9 ± 13. 1 years old.Coronary heart diseases and hypertension were the most common preexisting chronic diseases in the studied patients. The ROSC rate and discharge rates after survival in 1125 patients with CPR were 23. 8％ and 7.4％ respectively. The ROSC rate and discharge rates after survival were 36. 3％ and 11.6％ in the in-hospital cardiac arrest (IHCA) group, respectively whereas 11.5％ and 3. 3％ in out-hospital cardiac arrest (OHCA) group. Of 188 patients with ventricular fibrillation/Pulseless ventricular tachycardia, the ROSC rate and discharge rate after survival were 58.0％and 21.8％,respectively. Of them, 448 (39. 8％ ) of the cardiac arrest patients had underlying cardiac causes, and the ROSC rate and discharge rate after survival were 36. 3％ and 11.5％ respectively in IHCA group whereas 11.6％ and 3. 3％ in OHCA group. The ROSC rate and discharge rate after survival were 69. 8％ and 7. 4％respectively in the tertiary hospitals whereas 30. 2％ and 7. 3％ in the secondary hospitals. Conclusions Patients experienced cardiac arrest were predominantly male. Coronary heart disease and hypertension were the two most common preexisting chronic diseases. The ROSC rate and discharge rate of patients with IHCA were higher than those with OHCA. ROSC rate and discharge rate after survival were higher in the ventriculat fibrillation/Pulseless ventricular tachycardia group than the other cardiac rhythms first witnessed groups. The time delayed of starting CPR after onset of cardiac arrest had a critical impact on survival and discharge rate in both IHCA and OHCA groups.

Objective To analyse the spectral patterns of complementarity determining region 3 (CDR3) length distribution of T lymphocyte receptor beta chain variable (TRBV) gene families in infiltrating T cells of the liver tissues and the peripheral blood samples of patients with chronic hepatitis B (CHB) in order to evaluate the characteristics of T cell clonal expansion. Methods The spectral patterns drift of TRBV gene families (the monoclonal/oligoclonal TCR β T cells) in the peripheral blood and hepatic tissues from 11 cases of CHB patients were analyzed by the real-time fluorescence quantitative reverse transcription polymerase chain reaction (FQ-PCR) with DNA melting curve analysis, and abnormal rates of TRBV gene families were compared between CHB patients and healthy control. The comparison of rates was done by chi square test. Results The gene melting spectral pattern of 26 TRBV families of the 11 CHB patients, no matter in the peripheral blood or hepatic tissue, showed either a single peak or prominent melting peaks, even disappeared for certain TRBV families. The abnormal rate of TRBV gene families in the hepatic tissues was significantly higher than that in the peripheral blood samples (x2 = 23. 246, P＜0. 01). What is more interesting was that some parts of TRBV families were identical in both the peripheral blood and the hepatic tissue in certain patients. TCR BV13.1, TCR BV17 and TCR BV22 fragments were found to be restricted used in both the peripheral blood and hepatic tissue by some CHB patients. Conclusions T cells in the peripheral blood and the hepatic tissues of CHB patients can develop clonal expansion to some extent.Parts of TRBV families are restricted used in the peripheral blood and hepatic tissue in some CHB patients, which offers a foundation for further studying the common specific spectral drift patterns of TRBV CDR3 gene in CHB patients.
