Objective To analyze the correlations of multimodal ultrasound parameters with Ki-67 and cytokeratin 5/6(CK5/6)in triple-negative breast cancer(TNBC).Methods A retrospec-tive analysis was conducted on 212 breast cancer patients in Jurong Hospital Affiliated to Jiangsu Uni-versity and Jiangsu Provincial People's Hospital from January 2017 to December 2023.The patients were divided into TNBC group(n=95)and non-TNBC group(n=117).Immunohistochemical stai-ning was used to detect the expression of Ki-67 and CK5/6 in both groups,and the correlations of ul-trasound parameters with Ki-67 and CK5/6 were analyzed.Results In the TNBC group,the positive rates of CK5/6 and Ki-67 were 69.47％(66/95)and 75.79％(72/95)respectively,while in the non-TNBC group,the positive rates were 23.93％(28/117)and 14.53％(17/117)respectively,with significant between-group differences(P＜0.05).In the TNBC group,patients with high and low level of CK5/6 showed significant differences in maximum lesion diameter,morphology,margin,aspect ratio,presence of calcifications,posterior acoustic pattern,lymph node metastasis,and distant metastasis(P＜0.05);similarly,patients with high and low level of CK5/6 demonstrated significant differences in distribution,enhancement pattern,and perfusion defects(P＜0.05);patients with high and low level of Ki-67 also exhibited significant differences in maximum lesion diameter,mor-phology,margin,aspect ratio,presence of calcifications,posterior acoustic pattern,lymph node me-tastasis,and distant metastasis(P＜0.05);additionally,patients with high and low level of Ki-67 showed significant differences in the enhanced range,distribution,and enhancement pattern(P＜0.05).Multivariate analysis revealed that clear margin,calcifications,and enhanced range were in-dependent influencing factors for CK5/6 positivity(P＜0.05),while enhancement pattern and en-hanced range were independent influencing factors for Ki-67 positivity(P＜0.05).Conclusion Ki-67 and CK5/6 have higher positive expression rates in TNBC patients,and multimodal ultrasound pa-rameters are correlated with Ki-67 and CK5/6.

OBJECTIVE: To analyze the intellectual landscape and emerging research trends of Chinese medicine (CM) in the management of pediatric asthma through a scientometric study. METHODS: Publications related to CM in the management of pediatric asthma were retrieved from the Web of Science Core Collection using relevant keywords. A scientometric study was performed using CiteSpace and VOSviewer. RESULTS: A total of 1,673 original articles and reviews from 1991 to 2019 were included in the analysis. The amount of annual publications had a gradual increase with time. USA was the major contributor both in country and institution analyses. Based on the co-citation, the published journals were grouped into 4 clusters. Keyword analysis indicated that the main hotspots were: (1) comprehensive management; (2) risk factors, mechanism, and prevalence; (3) prevention and treatment; (4) inflammation; and (5) environmental research. Lastly, we predicted that three emerging trends were quality of life promotion, immune response, and combination therapy. CONCLUSIONS CM research in the management of pediatric asthma will maintain the current trend of steady growth. This scientometric analysis may help scientists to identify the areas of interests and future directions in the field.

OBJECTIVE: To study the value of body fat mass measured by bioelectrical impedance analysis (BIA) in predicting abnormal blood pressure and abnormal glucose metabolism in children. METHODS: Stratified cluster sampling was used to select the students aged 6-16 years, and a questionnaire survey and physical examination were performed. The BIA apparatus was used to measure body fat mass. Body mass index (BMI), body fat mass index (FMI), and fat mass percentage (FMP) were calculated. Fasting blood glucose level were measured. RESULTS: A total of 14 293 children were enrolled, among whom boys accounted for 49.89%. In boys and girls, the percentile values (P, P, P, P, P, P, P, P) of FMI and FMP fitted by the LMS method were taken as the cut-off values. Based on the receiver operating characteristic curve analysis, the P values with a better value in predicting abnormal blood pressure and blood glucose metabolism were selected as the cut-off values for excessive body fat. When FMI or FMP was controlled below P, the incidence of abnormal blood pressure or abnormal glucose metabolism may be decreased in 8.25%-43.24% of the children. CONCLUSIONS The evaluation of obesity based on FMI and FMP has a certain value in screening for hypertension and hyperglycemia in children, which can be further verified in the future prevention and treatment of obesity and related chronic diseases in children.

OBJECTIVE: To observe the therapeutic effect of acupuncture on cancer-related fatigue (CRF) and to explore its possible mechanism. METHODS: A total of 80 patients with CRF were randomized into an observation group and a control group, and finally 67 patients completed the trial (36 patients in the observation group, 31 patients in the control group). Patients in the control group were treated with conventional chemoradiotherapy and symptomatic treatment, while no particular anti-fatigue intervention was adopted. On the basis of treatment in the control group, acupuncture was applied at Baihui (GV 20), Guanyuan (CV 4), Qihai (CV 6), Fengchi (GB 20), Zusanli (ST 36), Sanyinjiao (SP 6) in the observation group, once a day, 5 times as one course, with 2 days interval between each course, totally 4 courses were required. Before and after treatment, scores of functional assessment of cancer therapy-fatigue (FACT-F) in Chinese and McGill quality of life questionnaire (MQOL), serum levels of C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-α(TNF-α) and soluble TNF receptor-1 (sTNF-R1) were observed in the two groups. RESULTS: ①Compared before treatment, the FACT-F score was decreased after treatment in the observation group (<0.05), while there was no significant difference in the control group (<0.05). The change of the FACT-F score in the observation group was larger than that in the control group (<0.05). ②In the observation group, scores of physiological and psychological dimension were decreased (<0.05), score of social support dimension was increased after the treatment (<0.05). The score changes of physiological, psychological and social support dimension in the observation group were larger than those in the control group (all <0.05). ③After treatment, the serum levels of IL-6, TNF-α and sTNF-R1 were decreased in the observation group (<0.05), while the serum levels of CPR and IL-6 were increased in the control group (<0.05). The serum levels of CPR, IL-6 and TNF-α in the observation were lower than those in the control group (<0.05). CONCLUSION ①Acupuncture can improve the related symptoms of depression, weakness and headache in patients with CRF, strengthen their cognition of the support from society and family, and boost the confidence in curing the disease. ②Acupuncture can effectively down-regulate serum levels of the relative inflammatory factors, which may be its possible mechanism on treating CRF.

Objective Few studies are reported on the prevention and management of oral mucositis(OM) induced by post-operative radiotherapy in patients with oral cavity cancer.This study aimed to investigate the therateutic effect of the recombinant human epidermal growth factor(rhEGF) gel on radiation-induced OM. Methods Sixty-eight cases of radiation-induced OM after surgery for oral cavity cancer were randomly divided into an experimental and a control group of equal number,the former treated with rhEGF gel while the latter with borax mouthwash. Comparisons were made between the two groups of patients in the severity of oral cavity mucous membrane injury,the intensity of radiation-induced oral pain,the in-cidence of oral cavity infection, and the duration of radiotherapy. Results At 3 weeks of radiotherapy,the patients of the experimental group showed mainly mild and moderate OM while the controls chiefly moderate and severe OM,and at 6 weeks,the former exhibited mainly moderate while the latter chiefly severe OM, with statistically significant differences in the incidence rate between the two groups (P<0.01). The experimental group, compared with the controls, had a significantly higher incidence rate of grade-Ⅰ radiation-induced pain (47.1% vs 20.6%,P<0.01),but lower rates of grade-Ⅱ(17.6% vs 32.4%,P<0.01) and grade-Ⅲpain(2.9% vs 20.6%,P<0.01).The rates of oral infection and antibiotics medication were remarkably lower in the experimental group than in the controls(23.5% vs 38.2% and 11.8% vs 26.5%,P<0.05),and the duration of radiotherapy was markedly shorter in the former than in the latter ([42.37±3.14] d vs [48.47±4.39] d, P<0.05). Conclusion The rhEGF gel can significantly reduce the severity of radiation-induced oral mucositis,improve its symptoms,and shorten the time of postoperative radiotherapy for patients with oral cavity cancer.

BACKGROUNDThe optimal timing of surgical revascularization for patients presenting with ST-segment elevation myocardial infarction (STEMI) and impaired left ventricular function is not well established. This study aimed to examine the timing of surgical revascularization after STEMI in patients with ischemic heart disease and left ventricular dysfunction (LVD) by comparing early and late results.

METHODSFrom January 2003 to December 2013, there were 2276 patients undergoing isolated coronary artery bypass grafting (CABG) in our institution. Two hundred and sixty-four (223 male, 41 females) patients with a history of STEMI and LVD were divided into early revascularization (ER, <3 weeks), mid-term revascularization (MR, 3 weeks to 3 months), and late revascularization (LR, >3 months) groups according to the time interval from STEMI to CABG. Mortality and complication rates were compared among the groups by Fisher's exact test. Cox regression analyses were performed to examine the effect of the time interval of surgery on long-term survival.

RESULTSNo significant differences in 30-day mortality, long-term survival, freedom from all-cause death, and rehospitalization for heart failure existed among the groups (P > 0.05). More patients in the ER group (12.90%) had low cardiac output syndrome than those in the MR (2.89%) and LR (3.05%) groups (P = 0.035). The mean follow-up times were 46.72 ± 30.65, 48.70 ± 32.74, and 43.75 ± 32.43 months, respectively (P = 0.716). Cox regression analyses showed a severe preoperative condition (odds ratio = 7.13, 95% confidence interval 2.05-24.74, P = 0.002) rather than the time interval of CABG (P > 0.05) after myocardial infarction was a risk factor of long-term survival.

CONCLUSIONSSurgical revascularization for patients with STEMI and LVD can be performed at different times after STEMI with comparable operative mortality and long-term survival. However, ER (<3 weeks) has a higher incidence of postoperative low cardiac output syndrome. A severe preoperative condition rather than the time interval of CABG after STEMI is a risk factor of long-term survival.

OBJECTIVETo investigate the long-term outcomes of off-pump coronary artery bypass grafting (OPCAB) in patients aged over 75 years and analyze the risk factors affecting the outcomes of the procedure.

METHODSClinical data were reviewed for 97 consecutive patients aged 75 years or above receiving OPCAB at our center between November, 2000 and November, 2013. The perioperative data including length of ICU stay, duration of mechanical ventilation, incidence of postoperative complications and mortality rate of the patients were analyzed. The follow-up data of the patients were also analyzed including all-cause mortality rate and major adverse cardiac and cerebral events (MACCE, including myocardial infarction, cerebrovascular event, and repeated revascularization).

RESULTSThe perioperative mortality rate was 3.09% (3/97) in these patients. Of the 97 patients analyzed, 91 (93%) were available for follow-up for 29-192 months (with a median of 95.61∓34.07 months). The 10-year survival rate of the patients was 62% with a 10-year MACCE-free survival rate of 47.4%. During the follow-up, 6 (6.8%) patients underwent repeated revascularization procedures, 12 (12.37%) had cerebrovascular accidents and 5 (5.15%) had myocardial infarction. Logistic regression analysis showed that hypertension (OR=1.388, P=0.043) and diabetes (OR=1.692, P=0.017) were independent predictors of MACCE, and incomplete revascularization did not increase the risk of postoperative MACCE.

CONCLUSIONOPCAB is safe and effective in elderly patients with good long-term outcomes. Hypertension and diabetes are independent risk factors of MACCE, and adequate control of blood pressure and blood glucose can reduce the incidence of postoperative MACCE. Incomplete revascularization is not detrimental to the long-term outcomes of OPCAB in elderly patients.

Objective To analyze the clinical characteristics of pituitary stalk interruption syndrome(PSIS). Methods The clinical data including clinical manifestations,laboratory tests,and imaging findings of 114 PSIS patients in our hospital were retrospectively analyzed. Results Of these 114 PSIS patients,102 cases (89.4%) were male. The average age was 21.1?6.1 years. A history of breech delivery was documented in 91 cases (91.9%). Short stature was found in 89 cases (71.8%) and bone age delayed (6.1?5.1) years. Secondary sex characteristics were poor or undeveloped in most patients. The prevalence of deficiencies in growth hormone,gonadotropins,corticotropin,and thyrotropin were 100.0%,94.0%,84.2%,and 74.6%,respectively. Hyperprolactinemia was found in 28.1% of patients. Three or more pituitary hormone abnormalities were found in 105 cases(92.1%). Compared with the 5 cases with history of cephalic delivery,no difference were found in the aspects of height(t=0.297,P=0.634),penile length(t=1.205,P=0.882),testicular volume (U=99.000,P=0.348),growth hormone peak (U=89.000,P=0.186),adrenocorticotropic hormone peak(U=131.000,P=0.967),luteinizing hormone peak(U=98.500,P=0.582),thyroid-stimulating hormone (U=82.000,P=0.162),and the height of anterior pituitary (t=1.676,P=0.107) in the 53 cases with history of breech delivery. Conclusions The clinical manifestations,symptoms,hormone deficiencies were severe in our series. The condition severities were not remarkably different in patients with different delivery ways.
