China Pharmacy 2005;0(23):-
OBJECTIVE:To improve the quality standard for Jingwu oral liquid.METHODS:The qualitation of Radix Polygoni Multiflori preparata and solomonseal rhizome in Jingwu oral liquid were identified by TLC and the assaying of 2,3,5,4’—tetra—hydroxyl diphenyl ethylene—2—O—?—D—glucoside in the oral liquid were determined by HPLC.RESULTS:In the TLCs of Radix Polygoni Multiflori preparata and solomonseal rhizome,the color of speckles was the same as that of the control articles in the corresponding places.The linear range of 2,3,5,4’—tetra—hydroxyl diphenyl ethylene—2—O—?—D—glucoside was 0.0 562?g~0.6 744?g(r=0.9 996);The average recovery was 100.1%(RSD=1.89%).CONCLUSION:The method is simple,fast,and reproducible and of high recovery rate,which can be used as quality control for Jingwu oral liquid.
2.Neoadjuvant systemic therapy for breast cancer
Journal of International Oncology 2013;(1):32-35
Neoadjuvant systemic therapy for breast cancer patients means systemic treatments before operations.Combination chemotherapy,endocrine therapy and targeted therapy before operation can degrade the tumor staging and increase the breast-conserving rates.Neoadjuvant chemotherapy has been accepted as one of the standard therapies for patients with locally advanced breast cancers.In the neoadjuvant setting,the studies about the use of aromatase inhibitors and trastuzumab in selected patients have also made great progresses.

Chinese Journal of Primary Medicine and Pharmacy 2014;(10):1463-1465
Objective To explore the correlation of serum ferritin (SF),fibrinogen(FIB) and D-dimer levels in patients with small vessel disease(SVD).Methods 359 patients with SVD were selected,including 186 patients with lacunar infarction ( LI) and 173 patients with leukoaraiosis ( LA) .176 healthy controls were enrolled in this study as control group.The SF,FIB and D-dimer concentrations were measured by radioimmunoassay method and Clauss method respectively .Results The serum levels of SF , FIB and D-dimer in SVD patients were significantly higher than those in the controls [(171.82 ±156.28)μg/L vs (100.37 ±70.11)μg/L,(3.27 ±0.93) g/L vs (2.97 ± 0.88)g/L,(1.10 ±1.06)mg/L vs (0.83 ±0.55)mg/L](all P<0.05).Compared with LI subgroup,the levels of SF,FIB and D-dimer were higher in LA subgroup [(185.22 ±108.55)μg/L vs (159.36 ±89.69)μg/L,(3.32 ± 0.86)g/L vs (3.23 ±0.99)g/L,(1.29 ±1.17)mg/L vs (1.03 ±0.80)mg/L],but the differences were not signifi-cant(all P<0.05).Multivariate regression analysis revealed that by comparison to the reference quartile ,the odds ra-tio (95%CI) for SVD patients in the higher quartile (SF>151.16μg/L,D-Dimer>1.02 mg/L) were 3.444(95%CI=2.097-5.158,P<0.001) and 1.767(95%CI=1.114-2.803,P=0.016),respectively after multivariable ad-justment.Conclusion The increased levels of SF ,FIB and D-dimer are closely related with SVD .FIB and D-dimer might come to be attractive approaches to prevent the progress of SVD .
4.The clinical value of liquid tumor biomarker detection for breast cancer
China Oncology 2014;(8):636-640
Circulating tumor markers have been paid more attention in the application of the treatment for breast cancer, the level of which has extended from protein to gene, including traditional tumor markers, HER-2 extracellular domain, circulating tumor cells, circulating tumor DNA (ctDNA), circulating RNA (ctRNA) and so on. As “liquid detection”, the detection of circulating tumor markers with real-time dynamic, easy operation, good reproducibility and other advantages are widely used in aiding early diagnosis, determining prognosis, prospectively predicting response or resistance to speciifc therapies, surveillance after primary surgery, and monitoring therapy in patients with advanced disease, The further study of circulating tumor markers may contribute to patient’s individual treatment.

Chinese Journal of Bases and Clinics in General Surgery 2003;0(03):-
Objective To review the recent studies about sentinel lymph node biopsy in breast cancer. Methods The literatures in recent years on the history, concept, technique and clinical application of sentinel lymph node biopsy were reviewed and summarized.Results There was no unified method for sentinel lymph node biopsy. There was a wide range of detection rate and false negative rate.Conclusion Prospective multi center random clinical trials will help to evaluate the clinical application of sentinel lymph node biopsy.
6.Inhibitory effects of melatonin on breast cancer
Journal of Central South University(Medical Sciences) 2017;42(3):346-351
Melatonin has a significant inhibitory effect on various cancers,especially on breast cancer.In estrogen receptor (ER)-positive human breast cancer,anti-cancer effects ofmelatonin on breast cancer cells and transplanted tumors mainly achieve by suppressing ER mRNA expression and ER transcriptional activity via the MT1 receptor.In addition,melatonin regulates the transactivation of other members of the nuclear receptor super-family,estrogen metabolizing enzymes,and the expression of related genes.Furthermore,melatonin also suppresses tumor aerobic metabolism,critical cell-signaling pathways relevant to cell proliferation,survival,metastasis,and drug resistance.Melatonin demonstrates both cytostatic and cytotoxic activity in breast cancer cells that appears to be cell-type specific.Studies on animal and human models indicate that disruption of the circadian nocturnal melatonin signal promotes the growth,metabolism,and signaling of human breast cancer,resulting in invalid hormone therapy and chemotherapeutic resistance in breast tumors.
7.Recent research advances in the relationship between caffeine intake and atrial fibrillation
Journal of Shanghai Jiaotong University(Medical Science) 2017;37(3):411-413
Atrial fibrillation is one of common arrhythmias and can significantly increase risks of stroke and heart failure with high rates of mortality and disability. The incidence of atrial fibrillation increases year by year due to aging population, high incidences of coronary heart disease and hypertension, and lifestyle changes. As one of widely consumed drinks in the world, coffee affects the daily life of modern people. The intake of caffeine, which is the main ingredient of coffee, can influence the incidence of atrial fibrillation, but the relationship between them is still controversial. Most studies deem that the intake of caffeine is negatively correlated with the incidence of atrial fibrillation. This paper reviews current studies in China and abroad on the relationship between the intake of caffeine and the incidence of atrial fibrillation.

Parenteral & Enteral Nutrition 2004;0(05):-
Objectives: To observe the clinical effects of nutritional support with protein diet in patients with moderate and severe burns. Methods: 50 cases were randomly divided into treatment group(25 cases) and control group(25 cases). The control group was treated with routine and nutritional support. The treatment group was given additionally with protein diet (80g/d,consisting of Gln 4g and protein 66g). Either oral admistration or tube feeling was chosen according to patient condition. The treatment lasted 21 days. Results: There was no significant difference between the two groups on the levels of Alb、PA、TF and TLC before the management. The level of Alb in the treatment group was obviously changed after the management. The levels of PA、 TF and TLC in the treatment group were increased significantly and had significant differences between the two groups(P
