ABSTRACT
By consulting ancient and modern literature， the herbal textual research of Farfarae Flos has been conducted to verify the name， origin， producing area， quality evaluation， harvesting and processing methods， so as to provide reference for the development and utilization of the famous classical formulas containing Farfarae Flos. According to the research， the results showed that Farfarae Flos was first described as a medicinal material by the name of Kuandonghua in Shennong Bencaojing（《神农本草经》）， and the name was used and justified by later generations. The main origin was the folwer buds of Tussilago farfara， in addition， the flower buds of Petasites japonicus were used as medicine in ancient times. The ancient harvesting time of Farfarae Flos was mostly in the twelfth month of the lunar calendar， and the modern harvesting time is in December or before the ground freeze when the flower buds have not been excavated. Hebei， Gansu， Shaanxi are the authentic producing areas with the good quality products. Since modern times， its quality is summarized as big， fat， purple-red color， no pedicel is better. Processing method from soaking with licorice water in the Northern and Southern dynasties to stir-frying with honey water followed by micro-fire in the Ming dynasty， and gradually evolved to the modern mainstream processing method of honey processing. Based on the research results， it is suggested that the dried flower buds of T. farfara， a Compositae plant， should be selected for the development of famous classical formulas containing Farfarae Flos， and the corresponding processed products should be selected according to the specific processing requirements of the formulas， and raw products are recommended for medicinal use without indicating processing requirements.
ABSTRACT
Through reviewing ancient and modern literature， the textual research of Anemarrhenae Rhizoma（AR） has been conducted to verify the name， origin， changes in production areas， quality evaluation， harvesting and processing methods， so as to provide reference for the development and utilization of the famous classical formulas containing AR. Through the herbal textual research， AR was first published in Shennong Bencaojing， and has been used as the proper name for this herb for generations， and the mainstream source of AR used for generations is the rhizome of Anemarrhena asphodeloides. The high-quality production areas that have been revered throughout the ages are Hebei， Shanxi， Shaanxi， Inner Mongolia and Fangshan district of Beijing， etc. In recent times， AR produced in Yixian county of Hebei province（Xiling Zhimu）， is better known and is regarded as a very good source. At present， cultivated AR is mainly produced in Yixian county and Anguo of Hebei province， Bozhou of Anhui province and other places. The medicinal parts of AR in ancient and modern times are all rhizomes， and the quality is better if it has thick flesh， hard wood， yellow outer color and white section color. The harvesting time recorded in ancient medical books is usually in lunar February and August， with exposure to dryness， while modern harvesting is spring and autumn. The processing methods of the past dynasties were mainly to remove the hair when using， avoid iron when cutting， process with wine or salt water， while the two main specifications in modern times are raw and salted products. Based on the systematic research， it is recommended that the dried rhizome of A. asphodeloides in the famous classical formulas be used for AR. If the original formula specifies processing requirements， it should be operated according to the requirements， if the processing requirements are not indicated， the raw products can be used as medicine.
ABSTRACT
AIM:To evaluate the correlation between axial lengths and anterior segment parameters using swept-source optical coherence tomography(SS-OCT).METHODS:For the cross-sectional clinical study, a total of 109 adult volunteers with different degrees of myopia recruited from January 1, 2022, to March 31, 2022, at the ophthalmology clinic of the First Affiliated Hospital of Zhengzhou University were included. Participants were divided into 4 groups based on axial length(AL): group A(AL≤24.0mm), group B(24.0mm<AL≤25.0mm), group C(25.0mm<AL≤26.0mm)and group D(AL>26.0mm). Anterior segment examinations were performed using SS-OCT, including: central corneal thickness(CCT), lens thickness(LT), anterior chamber depth(ACD), anterior chamber width(ACW), angle opening distance(AOD500), angle recess area(ARA500), trabecular iris space area(TISA500), trabecular iris angle(TIA500), crystalline lens rise(CLR). The relationships between these data and AL, spherical equivalent(SE)were analyzed.RESULTS:There was no difference in the comparison of CCT among the four groups(P>0.05). There were differences in SE, LT, ACD, ACW, AOD500, ARA500, TISA500, TIA500 and CLR among the four groups(all P<0.01). SE and LT were negatively correlated with AL(r=-0.75, -0.41, all P<0.01); ACD, ACW and CLR were positively correlated with AL(r=0.58, 0.45, 0.54, all P<0.01); AOD500, ARA500, TISA500 and TIA500(temporal and nasal side)were positively correlated with AL(all P<0.01). ACD and CLR were negatively correlated with SE(r=-0.21,-0.25, all P<0.01), and LT was positively correlated with SE(r=0.21, P<0.05).CONCLUSION:As AL increases, CCT remains unchanged while the ACD and ACW increase. The position of the crystalline lens moves backward and LT decreases.
ABSTRACT
Objective:To analyze and evaluate the safety and efficacy of a Chinese domestically manufactured Heart Con-type implantable third-generation magnetic and hydrodynamic levitation left ventricular assist device(LVAD) for the treatment of end-stage heart failure(ESHF), by reporting the results of eleven-center clinical trial on 50 cases.Methods:This study was a multicenter clinical trial, designed by means of prospective, multicenter and single-group target value. 50 subjects with ESHF were competitively enrolled and treated with HeartCon as the LVAD in eleven centers. The primary efficacy measure was survival, defined as either the subjects experiencing the transition to heart transplantation(HT) or myocardial recovery assisted by the device within 90 days, or as successfully assisted by the LVAD for full 90 days after implantation. The target survival rate was 60%, other observations included implantation success rate, mortality, pump failure needing replacement or emergency heart transplantation.Results:All enrolled 50 patients received LVAD implantation successfully, 46 survived with the pump for 90 days, 1 patient transitioned to heart transplantation, and 3 patients experienced pump thrombosis, within which 2 patients underwent pump replacement and continued to live with the pump for 90 days, and the other one received emergency heart transplantation. There were no dropout subjects. The survival rate at full 90 days after HeartCon implantation was 100%. The survival rates with pump in the full set analysis and the protocol set analysis were 96.00% and 95.92% respectively, which were higher than the target value of 60%. The differences were both statistically significant( P<0.05). Conclusion:The results of the multicenter clinical trial with the largest sample size in China using domestically manufactured third-generation LVAD has demonstrated that, HeartCon is a safe and effective LVAD to treat ESHF patients.
ABSTRACT
Objective:To analyze the short-term effects of prophylactic intraperitoneal hyperthermic chemotherapy(HIPEC)on elderly patients diagnosed with gastric cancer.Methods:The study enrolled patients with gastric cancer who underwent curative gastrectomy combined with postoperative HIPEC at Beijing Hospital between January 2017 and September 2022.The patients were divided into two groups based on age: young patients(age <65 years, n=45)and elderly patients(age≥65 years, n=32). The study evaluated the safety of HIPEC prophylactic application in elderly patients with gastric cancer by comparing their clinicopathological data, postoperative recovery, complications, and laboratory tests with those of another group of patients.Results:The study found that the elderly patients had a higher rate of comorbidities and higher ASA scores compared to the younger patients.Additionally, the elderly patients received HIPEC treatment less frequently than the younger patients( P=0.030). The proportion of young patients receiving one, two, and three times of HIPEC treatment was 8.9%, 57.8%, and 33.3%, respectively, while the proportion of elderly patients receiving the same was 28.1%, 59.4%, and 12.5%, respectively.The study found no significant differences in pathological characteristics between the two groups, including tumor stage, type, location, and differentiation degree.Additionally, there was no difference in the proportion of laparoscopic gastrectomy, type of resection, combined resection, duration of the operation, and intraoperative blood loss between elderly and young patients.The rate of complications between the two groups was also not significantly different(20.0% vs.21.9%; P=0.100). The mean duration of hospitalization after radical gastrectomy was 14.0 days in the young group and 15.5 days in the elderly group, respectively( P=0.480). Conclusions:Elderly patients with gastric cancer treated with radical gastrectomy combined with HIPEC did not experience increased postoperative complications or hospital stay compared to young patients, suggesting that prophylactic HIPEC was safe and feasible for elderly patients with locally advanced gastric cancer, as evidenced by favorable postoperative recovery and laboratory tests.
ABSTRACT
Objective:To examine the occurrence of complications in elderly patients who have undergone radical surgery for colorectal cancer.Additionally, this study aims to identify the various risk factors associated with these complications.Methods:This study included elderly patients with colorectal cancer who underwent radical surgery at Beijing Hospital between January 2013 and December 2020.These patients were divided into two groups based on their age.In this study, we examined a total of 906 patients who underwent surgery, with 695 patients under the age of 80 and 211 patients aged 80 and above.We classified postoperative complications into two categories: medical and surgical complications.Our analysis compared comorbidities, clinicopathological factors, perioperative variables, and postoperative morbidity and mortality between the two age groups.We utilized both univariate and multivariate analyses to identify any potential risk factors for postoperative morbidity.Results:When comparing patients under 80 years old to those aged 80 or older, it was found that the latter group had a lower body mass index, worse ASA scores, and more comorbidities.Additionally, the proportion of elderly patients with right colon cancer, pT3-4, and pN+ disease was higher compared to those under 80 years old.Furthermore, the elderly patients aged 80 or older had a lower rate of laparoscopic surgery compared to those under 80 years old.The study found that elderly patients aged 80 years and older had significantly shorter operation times compared to those younger than 80 years[(191.0±70.6)min vs.(214.0±83.3)min, t=3.642, P<0.001]. However, the overall complication rate was higher in the elderly group(32.7%)than in the younger group(22.6%)( χ2=8.839, P=0.004). Upon further analysis, it was found that medical complications increased significantly(20.9% vs.7.5%, χ2=30.547, P<0.001), whereas the rate of surgical complications did not show any statistical difference(15.6% vs.16.4%, χ2=0.069, P=0.832). The mortality rate during the perioperative period was found to be significantly higher in elderly patients aged 80 years and above compared to those below 80 years(1.9% vs.0.3%, χ2=6.316, P=0.029). Further analysis revealed that age was an independent risk factor for medical complications( HR=2.822, 95% CI: 1.804-4.414, P<0.001). Laparoscopic surgery has been shown to significantly decrease surgical complications( HR=0.475, 95% CI: 0.317-0.711, P=0.001). However, if the operation time exceeds 200 minutes, there is a significant increase in surgical complications( HR=1.942, 95% CI: 1.278-2.888, P=0.002). Conclusions:The incidence of postoperative medical complications in very elderly patients with colorectal cancer who undergo radical surgery has risen, although the rate of surgical complications has remained steady.Radical surgery for elderly patients with colorectal cancer is both safe and feasible, but it is important to prioritize the prevention and management of medical complications.
ABSTRACT
Objective:To evaluate the short-term efficacy of left colonic artery preservation in laparoscopic-assisted radical resection in elderly patients with rectal cancer.Methods:168 patients aged 65 and over who had undergonelaparoscopic-assisted radical resection of rectal cancer in the gastrointestinal surgery department of Beijing Hospital from December 2017 to December 2020 were retrospectively analyzed.According to different surgical methods, they were divided into the observation group with 90 subjects(the LCA group)and the control group with 78 subjects(the non-LCA group).Basic data, intraoperative, postoperative and clinicopathological data of the two groups were compared and analyzed.Results:There were no statistically significant differences between the two groups in operative time[(172.3±35.5)min vs.(155.5±28.7)min, t=2.182, P=0.103], intraoperative blood loss[(72.6±22.5)ml vs.(67.3±18.4)ml, t=1.473, P=0.128], number of group 253 lymph nodes dissected[(3.8±1.5) vs.(4.2±1.6), t=0.785, P=0.221], and total number of lymph nodes dissected[(14.1±4.3) vs.(15.8±5.0), t=1.652, P=0.113].There was no significant difference in the incidence of anastomotic hemorrhage[4.4%(4/90) vs.3.8%(3/78), χ2=1.182, P=0.133]and the incidence of urinary retention[4.4%(4/90) vs.6.4%(5/78), χ2=1.785, P=0.148].The time to first postoperative flatus[(52.4±23.2)h vs.(68.3±29.3)h, t=2.652, P=0.023]and length of postoperative hospital stay[(9.07±3.56)d vs.(10.68±4.94)d, t=2.785, P=0.017]in the LCA group were shorter than those in the non-LCA group.The incidences of anastomotic leakage in the LCA group and the non-LAC group were 2.2%(2/90)and 5.1%(4/78), respectively, and the difference was statistically significant( t=3.575, P=0.001). Conclusions:LCA preservation in laparoscopic-assisted radical resection of rectal cancer in elderly patients with rectal cancer is safe and feasible, reduces the incidence of anastomotic leakage, and shorten the time to first postoperative flatus and length of postoperative hospital stay.It has good practical clinical value.
ABSTRACT
Objective:To analyze the risk factors for postoperative adverse cardiovascular events(PACE)in elderly patients after treatment with colectomy.Methods:Clinical data of 720 elderly patients aged 65 years and over treated with colectomy from January 2012 to December 2019 in Beijing Hospital, National Center of Gerontology were analyzed retrospectively.According to the occurrence of PACE(non-fatal myocardial infarction, acute coronary syndrome, arrhythmia, heart failure/cardiac insufficiency, etc.), the cases were divided into the PACE group and the non-PACE group.Clinical data of the two groups were compared and the risk factors for PACE were investigated using multivariate Logistic regression.Results:The overall incidence of PACE was 5.8%(42/720). Statistically significant differences were found between the PACE and non-PACE groups in patient age, the American Society of Anesthesiologists(ASA)classification, the Goldman index score and comorbidities(coronary heart disease, arrhythmia, old myocardial infarction, chronic renal insufficiency), preoperative serum levels of BNP and D-dimmer, and postoperative length of stay( P<0.05). A further multivariate Logistic regression analysis showed that significant differences existed between the groups in NYHA Ⅲ and Ⅳ, ASA Ⅲ and old myocardial infarction, with the overall risk of PACE increasing by 4.017, 2.320 and 2.746, respectively. Conclusions:The incidence of PACE following colectomy is related to multiple perioperative factors.For elderly colorectal cancer patients with one or more of the above risk factors, we should be on high alert for PACE during hospitalization.
ABSTRACT
Bromodomain containing protein 4 (BRD4), as an epigenetic reader, can specifically bind to the acetyl lysine residues of histones and has emerged as an attractive therapeutic target for various diseases, including cancer, cardiac remodeling and heart failure. Herein, we described the discovery of hit 5 bearing 4-phenylquinazoline skeleton through a high-throughput virtual screen using 2,003,400 compound library (enamine). Then, structure-activity relationship (SAR) study was performed and 47 new 4-phenylquinazoline derivatives toward BRD4 were further designed, synthesized and evaluated, using HTRF assay set up in our lab. Eventually, we identified compound C-34, which possessed better pharmacokinetic and physicochemical properties as well as lower cytotoxicity against NRCF and NRCM cells, compared to the positive control JQ1. Using computer-based molecular docking and cellular thermal shift assay, we further verified that C-34 could target BRD4 at molecular and cellular levels. Furthermore, treatment with C-34 effectively alleviated fibroblast activation in vitro and cardiac fibrosis in vivo, which was correlated with the decreased expression of BRD4 downstream target c-MYC as well as the depressed TGF-β1/Smad2/3 signaling pathway. Taken together, our findings indicate that novel BRD4 inhibitor C-34 tethering a 4-phenylquinazoline scaffold can serve as a lead compound for further development to treat fibrotic cardiovascular disease.
ABSTRACT
Objective:To investigate the short-term and long-term efficacy of laparoscopic surgery for colorectal cancer in elderly patients aged 80 and over.Methods:This study included patients aged 80 and over with sigmoid or rectal cancer who had undergone radical surgery in Beijing Hospital between January 2013 and December 2020.Of the enrolled patients, 47 underwent laparoscopic surgery, and 44 received open surgery.After 1∶1 propensity score matching(PSM), there were 32 cases in each group.Patient clinicopathological characteristics, surgery data, post-operative outcomes and long-term survival were compared.Results:Before PSM, there were significant differences in sex composition and tumor locations between the open surgery and laparoscopic surgery groups.After PSM, there was no significant difference in clinicopathological characteristics between the two groups.Before and after PSM, the operative time for laparoscopic surgery was statistically longer than that for open surgery.The intraoperative blood loss, the postoperative complication rate and the number of harvested lymph nodes were not significantly different between the two groups before and after PSM.Before and after PSM, the postoperative hospital stay in the laparoscopic operation group was shorter than that in the open surgery group, but the difference was not statistically significant.Before PSM, the 1-year, 3-year and 5-year survival rates of the open surgery group were 92.4%, 69.5% and 58.1%, respectively, and the 1-year, 3-year and 5-year survival rates of laparoscopic group were 91.3%, 79.8% and 69.5%, respectively.There was no significant difference in overall survival between the two groups before PSM( χ2=0.591, P=0.422). After PSM, the 1-year, 3-year and 5-year survival rates in the open surgery group were 89.3%, 67.1% and 52.2%, respectively, and the 1-year, 3-year and 5-year survival rates in the laparoscopic surgery group were 90.6%, 74.3% and 65.0%, respectively.There was no significant difference in the overall survival between the two groups after PSM( χ2=1.316, P=0.251). Conclusions:For elderly colorectal cancer patients aged 80 and over, laparoscopic surgery and open surgery have similar rates of complications and long-term survival.This study provides evidence for the safety of laparoscopic surgery.Further prospective randomized controlled clinical trials are needed to confirm these findings.
ABSTRACT
Ephedrae Herba is a commonly used medicine for dispersing wind and cold， which has a long medicinal history. By referring to the herbal literature， medical books and prescription books， this paper intends to carry out herbal textual research on the name， origin， medicinal part， producing area， harvesting and processing methods of Ephedrae Herba in famous classical formulas， in order to provide the basis for the development of relevant famous classical formulas. According to textual research， the main base of ancient Ephedrae Herba was Ephedra sinica. The medicinal part is the herbaceous stems of Ephedrae Herba. Before the Northern and Southern dynasties， the origin of the records was Jindi and Hedong， which is now Shanxi province. In the Northern and Southern dynasties and later generations， the producing area expanded， and now it is mainly distributed in Hebei， Shanxi， Shaanxi， Inner Mongolia， Gansu， Liaoning and other places， among which Inner Mongolia is the main producing area. The harvesting and processing methods in the past dynasties are to harvest the stems in autumn， dry them in the shade or air to 70%-80% dry， and then dry them in the sun. The processing methods in the past dynasties mainly include removing the knots， wine-fried， honey-fried， processing with vinegar and so on， at present， only honey-fried is still in use. Based on the research results， it is suggested that Ephedrae Herba in famous classical formulas should be selected the dry herbaceous stems of E. sinica. If the processing requirements are not indicated， it is suggested to use raw products of Ephedrae Herba.
ABSTRACT
In this paper， the name， classification， origin and other aspects of Schizonepetae Herba in the famous classical formulas were researched by referring to the related herbal literature， medical books and prescription books in the past dynasties. The results showed that Schizonepetae Herba first appeared in Shennong Bencaojing （《神农本草经》） as Jiasu， while Jingjie first appeared in Wupu Bencao （《吴普本草》）， and the name of Jingjie was mainly used as the rectification of name in later generations. The name of Jiasu is mostly derived from its smell， and the name of Jingjie is mostly derived from its pronunciation. Schizonepeta tenuifolia has been highly praised in the past as a original material， and its genuine producing area is Jiangsu， Hebei and other places， medicinal part is whole herb with spike. In modern times， the quality of Schizonepetae Herba is best described as having thin stems， green spike， and aroma. In clinical application， the raw products of Schizonepetae Herba is mainly used， and the carbonisata is mainly used for hemostasis. Famous classical formulas of Huaihuasan and Danggui Yinzi are all made of Schizonepetae Spica， so it is recommended to use the dried panicle of S. tenuifolia. In Liangxue Dihuangtang， Schizonepetae Herba Carbonisata is used， therefore， it is suggested to adopt the processing method of Schizonepetae Herba Carbonisata in the 2020 edition of Chinese Pharmacopoeia.
ABSTRACT
This research was used with high performance liquid chromatography(HPLC), combined with information entropy-response surface method(RSM) to investigate the ethanol concentration, extraction time, liquid-to-material ratio. Taking the content of four chromogens as evaluation indexes, the weight coefficients of each index were given, and the comprehensive score was calculated to optimize the extraction process. Then, prim-O-glucosylcimifugin was used as the reference, the relative calibration factors(RCFs) of cimifugin, 4'-O-β-D-glucosyl-5-O-methylvisamminol and sec-O-glucosylhamaudo to prim-O-glucosylcimifugin were calculated respectively. The contents of four components in Saposhnikoviae Radix were determined by both external standard method(ESM)and quantitative analysis of multi-components by single marker(QAMS) method, and the results were compared. At last, combined with principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) to evaluate the quality of the Saposhnikoviae Radix in different production areas. The optimal extraction process parameter of the Saposhnikoviae Radix was as follows: liquid-to-material ratio is 60∶1(mL·g~(-1)), extraction time is 35 min, and ethanol concentration is 70%. The repeatability of the RCFs was perfect, and the results calculated by the QAMS were consistent with the results from the ESM. The stoichiometric results indicate that there are obvious differences in the distribution of Saposhnikoviae Radix in different production areas, and cimifugin and prim-O-glucosylcimifugin are the characteristic compounds that cause this difference. In this study, the optimal extraction process is stable and feasible, and the method of QAMS is accurate and reliable. From the perspective of four chromogens, there are differences in the quality of the Saposhnikoviae Radix in different production areas. Therefore, the established extraction process combined with the method of QAMS can be used to evaluate the quality of Saposhnikoviae Radix and provide a scientific basis for the quality control of Saposhnikoviae Radix.

ABSTRACT
ObjectiveAt present, there are few reports on the therapeutic effect of probiotic supplements in patients with dietary-controlled gestational diabetes mellitus (GDM). This study aims to evaluate the effect of probiotic supplements on insulin resistance in patients with dietary-controlled GDM.Methods122 pregnant women with dietary-controlled GDM who could control blood glucose less than 92 mg/dL through diet and exercise were selected from the Obstetrics Department in Bayannur Hospital from February to December 2018. The patients were randomly divided into two groups: Probiotics Group (probiotic supplements containing bifidobacterium and lactobacillus) and Placebo Group (placebo capsules). 61 patients in each group were treated continuously for 4 weeks. The main evaluation index was the mean difference of fasting blood glucose, fasting plasma insulin and insulin resistance index (HOMA-IR) between the two groups, and the secondary evaluation index was the change of maternal weight after intervention.ResultsThe increase of fasting blood glucose [(0.59±6.42)mg/dL], fasting plasma insulin [(1.14±1.95)mIU/mL] and HOMA-IR (0.27±0.45) in the Probiotics Group after intervention were significantly lower than those in the Placebo Group [(4.78±7.47 mg/dL), (3.86±1.82) mIU/mL, (0.86±0.59)], and the difference was statistically significant (P 0.05).ConclusionDuring pregnancy, probiotic supplements for four weeks in patients with dietary-controlled GDM can reduce fasting blood glucose and increase insulin sensitivity. Therefore, probiotic supplements can be used as adjunctive therapy for blood glucose control in patients with dietary-controlled GDM.

ABSTRACT
The chemical constituents were isolated and purified by column chromatography and semi-preparative reversed-phase high performance liquid chromatography with silica gel, MCI and polyamide in order to study the chemical constituents of dried flowers of Osmanthus fragrans var. aurantiacus. Their structures were identified by the physical and chemical properties and one-dimensional nuclear magnetic resonance (1H-, 13C-NMR, DEPT), two-dimensional nuclear magnetic resonance (1H-1H COSY, non-decoupled HSQC, HSQC, HMBC), UV, IR and high resolution mass spectrometry data. One new compound (1) and five known compounds (2-6) were isolated from 95% ethanol extract of dried broccoli. They were identified as (9S)-9-hydroxymengastigm-5-en-4-one-9-O-primeveroside (1), oleanolic acid (2), forsythiaside (3), 2-(4-hydroxyphenethyl)-ethanol-(6-acetyl)-β-D-glucopyranoside (4), salidroside (5), and acteoside (6). Compounds (2-6) were isolated from this plant for the first time.
ABSTRACT
Objective To compare the diagnostic performances of ultrasonography and digital breast tomosynthesis (DBT) in women with dense breasts. Methods A total of 148 women (148 breast lesions) with dense breasts underwent DBT and ultrasonography. Then the patients were divided into groups according to the composition of the breast, patients' age, lesion size and with or without calcification. Taking pathological results as gold standards, ROC curve was used to evaluate the diagnostic performances of ultrasonography DBT, and the AUC, sensitivity and specificity of them were compared. Results AUC of ultrasonography and DBT in diagnosis of dense breast lesions was 0.956 and 0.815 (Z=3.866, P40-55 years (0.946 vs 0.801, P=0.013) groups. According to clinical diagnostic criteria, the sensitivity of ultrasonography and DBT in diagnosis of benign and malignant lesions in dense breast was 94.32% (83/88) and 93.18% (82/88, χ2=0.096, P=1.000), and the specificity was 83.33% (50/60) and 61.67% (37/60, χ2=7.060, P=0.007). Conclusion Ultrasonography shows better diagnostic performance than DBT in women with dense breast. Ultrasonography is suitable to be chosen as the preferred examination in women with small lesions in heterogeneously dense breasts and aged ≤55 years than DBT.

Objective To investigate the correlation between serum interleukin-6 (IL-6) to albumin ratio (IAR) at admission and early outcome of patients with acute noncardioembolic ischemic stroke.Methods From January 2013 to May 2015,patients with acute noncardioembolic ischemic stroke admitted to the Department of Neurology,the First Affiliated Hospital of Xi'an Jiaotong University were enrolled retrospectively.Three months after onset,the clinical outcome were assessed by the modified Rankin scale (mRS),0-2 was good outcome,and ＞ 2 was poor outcome.The baseline clinical data,laboratory tests,and IAR in both groups were compared.Multivariate logistic regression analysis was used to determine the independent risk factors affecting early outcomes.Receiver operating characteristic (ROC) curve was used to evaluate the predictive value of IAR for early outcome.Results A total of 236 patients were enrolled in the study,including good outcome in 143 (60.6％) and poor outcome in 93 (39.4％).Univariate analysis showed that age (62.99 ± 11.34 years vs.59.62 ± 11.83 years;t =-2.176,P=0.031),serum IL-6 (37.56 ± 3.82 ng/L vs.34.82 ± 3.13 ng/L;t =-6.016,P ＜ 0.001),IAR (1.02 ± 0.08 vs.0.93 ± 0.07;t =-9.474,P＜0.001),and the proportions of patients with severe stroke (6.5％ vs.0％;x2 =8.142,P =0.012) and combined CHD (30.1％ vs.18.2％;x2 =4.542,P =0.033) of the poor outcome group were significantly higher than those of the good outcome group.Multivariate logistic regression analysis showed that high IAR at admission was an independent risk factor for early poor outcome (odds ratio,5.192,95％ confidence interval 3.283-8.213;P ＜0.001).ROC curve analysis showed the optimal cut-off value of IAR predicting for early outcome was 1.00,and the area under the ROC curve was 0.807 (95％ confidence interval 0.748 to 0.860).The sensitivity was 62.4％,the specificity was 88.1％,the positive predictive value was 69.2％,the negative predictive value was 79.3％,and the accuracy was 75.4％.Conclusions High serum IAR at admission was an independent risk factor for early poor outcome in patients with acute noncardioembolic ischemic stroke.It had a certain predictive value for the outcomes.
