RESUMO
ObjectiveTo investigate effect of Maxing Shigantang and supplemented Guominjian decoction on symptoms and levels of inflammatory cytokines in induced sputum of children with cough variant asthma （CVA）. MethodA total of 118 CVA children who were treated in our hospital from January 2020 to January 2021 were enrolled and randomized into the control group and the observation group with the random number table method. Control group received routine western medicine and the observation group was treated by routine western medicine， Maxing Shigantang， and supplemented Guominjian decoction. In the one-month follow-up， the scores of cough and accompanying symptoms， levels of inflammatory cytokines ［interleukin-10 （IL-10）， interleukin-5 （IL-5）， tumor necrosis factor-α （TNF-α）， neutrophil， eosinophil］ in induced sputum， pulmonary function parameters ［forced vital capacity （FVC）， forced expiratory volume in one second （FEV1）， FEV1/FVC］， and treatment outcomes were compared between the two groups. Moreover， the frequency of acute asthma attacks during the three-month follow-up was also compared. ResultNo cases dropped out from this study. After treatment， the scores of cough and accompanying symptoms were decreased in both groups （P<0.05） and were lower in observation group than in control group （P<0.05）. After treatment， FVC， FEV1， and FEV1/FVC were raised in both groups and were higher in observation group than in control group （P<0.05）. The increase in the level of IL-10 along with the decrease in levels of IL-5， TNF-α， neutrophil， and eosinophil in induced sputum was found in both groups after treatment （P<0.05）， and observation group had higher level of IL-10 and lower levels of IL-5， TNF-α， neutrophil， and eosinophil than the control group （P<0.05）. The effective rate was 86.44% （51/59） in observation group， which was higher than the 69.49% （41/59） in control group （χ2=4.933， P<0.05）. No serious adverse reaction occurred in either group. The frequency of acute asthma attacks during the three-month follow-up was （1.09±0.18） in observation group， which was lower than the （2.83±049） in the control group （P<0.05）. ConclusionRoutine western medicine combined with Maxing Shigantang and supplemented Guominjian decoction can effectively and safely alleviate the airway inflammatory responses， control the clinical symptoms， improve pulmonary function， and reduce the frequency of acute recurrence in the treatment of CVA children.
RESUMO
Objective@#To evaluate the diagnostic efficiency in differential diagnosis for breast sentinel lymph nodes, and to analyze the imaging characteristics of involved breast sentinel lymph node in lymphatic contrast enhanced ultrasound.@*Methods@#Sixty-one patients suspected with breast cancer from May 2017 to March 2019 in Shanghai General Hospital, Shanghai Jiao Tong University were included in the study. Ultrasound contrast agent was injected subcutaneously, and axillary lymph nodes were displayed under contrast enhanced ultrasound mode. The longitudinal diameter (anteroposterior diameter), transverse diameter, longitudinal/transverse ratio and the distance from skin surface were measured. Five types were concluded according to the imaging characteristics in lymphatic contrast enhanced ultrasound: typeⅠ, uniform enhancement; type Ⅱ, ring-shape enhancement; type Ⅲ, ununiform enhancement; type Ⅳ, regional filling defect; type Ⅴ, total filling defect. Sentinel lymph nodes were guided by wire guides and verified in pathology after excision in the operation.@*Results@#The detection rate of sentinel lymph nodes was 95.08% (58/61). Seventy-seven lymph nodes, including 21 involved nodes and 56 uninvolved nodes were detected by lymphatic contrast enhanced ultrasound in 58 patients. The longitudinal diameters and transverse diameters of involved lymph nodes were larger than those of uninvolved ones (P=0.001, 0.003). When type Ⅳ(regional filling defect) and type Ⅴ(total filling defect) were classified as involved, the sensitivity, specificity, positive-predictive value, negative-predictive value, accuracy and the area under ROC curve of predicting sentinel lymph node metastases were 85.71%, 96.43%, 90.00%, 94.70%, 93.51% and 0.911, respectively.@*Conclusions@#Lymphatic contrast enhanced ultrasound reaches a high diagnostic efficiency in qualitative analysis of breast sentinel lymph nodes. Regional filling defect and total filling defect are the imaging characteristics of involved sentinel lymph nodes in lymphatic contrast enhanced ultrasound.

RESUMO
Objective:To discuss the application effect of quality management of quality control circle (QCC) for reducing re-washing rate of suction aspirator tip in the quality management of medical instrument of hospital.Methods: Through established QCC group to designate one topic, to investigate its current situation and to protocol project plan of quality management. The qualified rate of first washing of 904 suction aspirator tips was analyzed before control management of QCC was implemented, and then series of QCC methods including fishbone diagram were applied to analyze and confirm main factors. The protocol countermeasure, depend on above information, achieved improvement for washing quality of 856 suction aspirator tips after the quality management of QCC was implemented in practice. The re-washing rates of washing quality of suction aspirator tip between before and after QCC was applied were compared.Results: The qualified rate of first washing of 904 suction aspirator tips before the quality management of QCC was implemented was 65.7%, while it was 97.6% for 856 suction aspirator tips after quality management of QCC was implemented. The washing qualified rate of suction aspirator tip after quality management of QCC was applied was significantly higher than that before it was applied (x2=8.429,P<0.05), and the result has achieved the aim that continuous improved quality.Conclusion: The application of quality management of QCC can decrease re-washing rate of suction aspirator tip, and contribute to decrease cost, to increase work efficiency, to strengthen the attention and degree of involvement of staff for work quality. Therefore, the management can fully exert potential of member of quality management of QCC, and enhance washing quality of suction aspirator tips.
RESUMO
Objective To explore the role of CD4~+CD25~+CD127~(lo) regulatory T cells (Tregs) and inter-leukin (IL)-6, transforming growth factor beta (TGF-β), IL-17 in the pathogenesis of lupus nephritis (LN) by detecting the levels of IL-10, IL-6, TGF-β, IL-17, CD4~+CD25~+CD127~(lo) Tregs in the peripheral blood of patients with active and inactive LN. Methods Three-colour flow cytometry was used to quantitatively measure proportions of Treg cells, the levels of TGF-β, IL-17 were detected by ELISA, and the levels of IL-10, IL-6 in the peripheral blood were detected by Cytometric Bead Array System. Results ① Compared with the inactive LN and the normal controls (P<0.01), the level of CD4~+CD25~+CD127~(lo) Tregs from patients with active LN was lower(P<0.01). When compared with the normal controls, the level of CD4~+CD25~+CD127~(lo) Tregs from LN inactive patients had no significant difference (P>0.05). ② Compared with patients with inactive LN, the levels of IL-10, IL-6 was higher (P<0.01) in patients with active LN. ③ Compared with the patients with inactive LN and the normal controls, the levels of TGF-β, IL-17 was not significantly different (P>0.05). ④ The level of CD4~+CD25~+CD127~(lo) T cell was correlated negatively with the levels of IL-10, IL-6 and SLEDAI (P<0.05), and was not correlated with C3 and C4. ⑤ SLEDAI was correlated positively with the levels of IL-10 and IL-6 (P<0.01). SLEDAI and the level of IL-10 were correlated negatively with C3 and C4 (P<0.01 for both). ⑥ The level of CD4~+CD25~+CD127~(lo) Tregs from LN was not correlated with TGF-β and IL-17. ⑦ TGF-β was correlated positively with the level of IL-17. Conclusion ① The level changes of Tregs and IL-10, IL-6, TGF-β in the peripheral blood of LN can be used as the indicators for the activity status of lupus nephritis. ② Tregs and IL-10, IL-6 in the peripheral blood of LN patients is negatively correlated. ③ The glucocorticoid hormone is helpful to elevate the level of Tregs but decrease IL-17. T cell level can vary in different body status, different microenvironmental and immune status.
