Cancer Research and Clinic 2008;20(6):400-402
Objective To discuss the relationship age and pathologic type, tumor size (≥4 cm) and pelvic lymph metastasis in cervical cancer, and the relative factors of cervical cancer with metastasis of pelvic lymphaden and the possibility of ovarian conservation. Methods 166 cases of cervical cancer accepted radical hysterectomy and pelvic lymphadenectomy in our hospital from June 2002 to June 2007, and were analyzed retrospectively. 166 cases of cervical cancer were divided into two groups, the age in group A was less than 35, while in group B was more than 35. Results The possibility of adenocarcinoma, the tumor size (≥4 cm) and the metastasis of pelvic lymphaden were higher in group A than in group B. The higher the clinical stage, the higher the pathological type and grade were. The greater the tumor size were ,the higher the rate of pelvic lymphatic metastasis (P <0.01). The more tissue infiltrate were, the higher the rate of pelvic lymphatic metastasis (P <0.01). Conclusion The possibility of adenocarcinoma carcinoma, the tumor size (≥ 4 cm) and the metastasis of pelvic were more higher in young women. The rate of pelvic metastasis is closely related to clinical stage, pathological type and grade, tumor size, and tissue infitration.

Chinese Journal of Clinical Infectious Diseases 2009;2(3):159-161
Objective To investigate the significance of procalcitonin(PCT),C-reactive protein (CRP)and WBC counts in predicting the postoperative jnfections in patients with bone fractures.Methods Clinical data of 49 patients with open fractures were retrospectively analyzed,and the patients were grouped into the infeeted(n=24)and non.infected(n=25).PCT,CRP and WBC values were detected 1,4,7and 10 days after the operations,and the results were compared with those taken from the healthy controls.Areas under the receiver operating characteristic(ROC)curves were used to determine the value in predicting postoperative infections.Results PCT,CRP and WBC values in the infected group and the noninfected group were higher than those in health controls(F=19.84,57.71 and 35.44,P<0.01).PCT,CRP and WBC values in the infected group were higher than those in the non-infected group 4.7 and 10 days after the operations(tPCT=7.31,7.74 and 4.59;tCRP=2.23,5.75 and 8.01;tWBC=2.34,2.51 and 4.07,P<0.05).ROC curves suggested that PCT value was more sensitive and had higher specificity than CRP and WBC values in the diagnosis of postoperative infections.Conclusions PCT,CRP and WBC values arise in bone fracture patients with postoperative infections.Detection of PCT has higher sensitivity and specificity.which can be used in early diagnosis of postoperative infections.
3.Systematic perspective in the decision making of liver cancer management
Chinese Journal of Hepatobiliary Surgery 2011;17(12):959-962
Currently,as various liver cancer-related treatments in China become developed,doctors also become super-subspecialized.This results in the doctors having more specialized skills and knowledge but a narrower vision.There is a tendency for these super-subspecialists to think and to make decisions based on a narrow perspective.As a consequence,interdisciplinary collaboration is becoming difficult.This hinders further improvement of treatment of liver cancer which has reached a plateau for many years.The present paper proposes a systematic perspective in decisionmaking for treatment of liver cancer.There are seven aspects which include the basic nature of medical care,the history of development of treatment,liver anatomical and functional characteristics,multicentric tumour occurrence,pathology,tumor immunology and biology.We aim to broaden the doctors’ vision and optimize their clinical thinking process.
4.Progress in diagnosis and treatment for ductal carcinoma in situ
International Journal of Surgery 2011;38(12):835-838
Increases in diagnostic frequency of breast ductal carcinoma in situ(DCIS) have followed the introduction of mammographic screening in past years.It is very important to distinguish the clinical syndrome of DCIS.The management of surgery for DCIS includes mastectomy,lumpectomy plus radiotherapy and lumpectomy alone; axillary lymph node dissection(ALND) in DCIS has not been recommended and sentinel lymph node biopsy(SLNB) is still controversial; adjuvant radiotherapy for ipsilateral whole breast and endocrine treatment can reduce local recurrence,prevent second primary breast tumor,preclude regional and distant metastasis.But whatever we take towards the DCIS above,there is little disturbance to DCIS' s inherent prognosis.Doctors must pay enough attention to this point.

Journal of Medical Postgraduates 2003;0(03):-
Objective: To study the effects of glycosaminoglycan from scallop skirt (SS-GAG) on the formation of foam cells from porcine artery smooth muscle cells (SMCs) and the expression of the total superoxide dismutase(SOD)and glutathione peroxidase(GSH-PX)activity, NO production and the mechanism of anti-atherosclerosis action of SS-GAG. Methods: SMCs were incubated with 15 mg/L oxidized low-density lipoprotein (Ox-LDL) for 72 h to establish a smooth muscle cell-derived foam cell model. In addition, SMC cells were divided into 6 groups:①blank group,②model(Ox-LDL) group, ③Ox-LDL+200 mg/L SS-GAG group,④Ox-LDL+400 mg/L SS-GAG group,⑤Ox-LDL+800 mg/L SS-GAG group, ⑥Ox-LDL+Heparin 100 mg/L group. After 72 h incubation, intracellular total cholesterol (TC), free cholesterol (FC), cholesteryl ester (CE) content and CE/TC ratio were measured through enzymatic method. The SOD, GSH-PX and NO concentration in the medium were also determined through Xanthine oxidase method or TBARs. Results: TC, CE, CE/TC in model group significantly increased, while FC, GSH-PX and NO concentration in the medium significantly decreased compared with blank group. After treatment with heparin (100 mg/L) and different concentrations of SS-GAG (200 mg/L, 400 mg/L,800 mg/L), TC, CE, and CE/TC significantly decreased (P
6.Mitochondrial nitric oxide synthase: biological function
Academic Journal of Second Military Medical University 1985;0(06):-
Increasing evidences have shown the existance of a mitochondrial nitric oxide synthase(mtNOS),which binds to the matrix face of the mitochondrial inner membrane and produces nitric oxide(NO) through a Ca~(2+)sensitive pathway.Under physiological condition,the NO catalyzed by mtNOS regulates mitochondrial oxygen consumption and transmembrane potential via reversible competition with cytochrome C oxidase.The reaction of NO with superoxide anion,which was produced by mitochondrial respiratory chain,yields peroxynitrite.Peroxynitrite irreversibly modifies susceptible targets in mitochondria and induces oxidative and/or nitrative stress.In addition,NO has also been implicated in the programmed cell death.This article reviews the current understanding of mtNOS's role in the regulation of mitochondrial functions.

Journal of Integrative Medicine 2012;10(4):384-9
Hyperplastic disease of the breast (HDB) is caused by a hormone imbalance experienced among women at a certain age. Slight breast pain is common in women before menstruation without need of treatment; however, if the pain becomes severe, it can cause physical and mental suffering. Therefore, it is of great clinical significance to control this disease.
10.Early evaluation of paraquat plasma concentration and urine sodium dithionite assay for prognosis in patients ;with acute paraquat poisoning
Chinese Critical Care Medicine 2016;28(10):886-890
Objective To explore early prognostic value of quantitative detection of paraquat (PQ) plasma concentration and urine sodium dithionite assay for prognosis in patients with acute PQ poisoning. Methods A prospective study was conducted. The patients with acute PQ poisoning admitted to Department of Emergency of First Hospital of China Medical University from August 2013 to December 2015 were enrolled. At admission, blood samples and urine samples were collected. The PQ plasma concentration was determined by high-performance liquid chromatography (HPLC), and the PQ urine concentration was determined by sodium dithionite, meanwhile the biochemical parameters were determined to carry out sequential organ failure assessment (SOFA) score. According to the prognosis of 90-day follow-up, the patients were divided into survival group and death group. Logistic regression analysis was used to analyze the relationship between the prognosis and the indexes, and the receiver operating characteristic curve (ROC) was drawn to evaluate the prognosis. Results There were 148 patients with acute PQ poisoning, with 43 alive and 105 dead, and the 90-day mortality rate was 70.9%. The ingestion volume (mL: 22.69±18.57 vs. 9.91±4.61), plasma concentration of PQ (mg/L: 2.28±1.52 vs. 0.91±0.38) and positive rate of urine sodium dithionite (87.6% vs. 14.0%) in death group were significantly higher than those of survived group (all P < 0.01), but no significant differences in gender, age, poisoning time, gastric lavage time between the two groups were found. Significant differences in white blood cell count [WBC (×109/L): 13.45±6.12 vs. 23.03±7.67] and blood lactate [Lac (mmol/L): 1.50±0.45 vs. 8.10±4.51] between survival group and death group were found (both P < 0.01), while no significant difference in SOFA score was found (0.98±0.72 vs. 1.34±1.29, P > 0.05). It was shown by logistic regression analysis that the key factors affecting the prognosis of patients with PQ poisoning were urine sodium dithionite assay [odds ratio (OR) = 8.731, 95% confidence interval (95%CI) = 2.828-26.954, P = 0.000], PQ plasma concentration (OR = 2.082, 95%CI = 1.204-3.603, P = 0.009) and ingestion volume (OR = 1.175, 95%CI = 1.048-1.318, P = 0.006) respectively. It was shown by ROC curve that the area under ROC curve (AUC) of plasma PQ concentration, urine sodium dithionite assay, poisoning dose and SOFA score for predicting the prognosis in patients with acute PQ poisoning was 0.866, 0.857, 0.826, and 0.631 respectively (all P < 0.05). The sensitivity of urine sodium dithionite assay for predicting the prognosis was 87.6%, and the specificity was 83.7%. Conclusions Early plasma PQ concentrations can objectively reflect the body absorbed toxicant doses and actual situation after poisoning, and help to judge the early evaluation of prognosis. The accuracy of urine sodium dithionite assay in judging the prognosis of PQ poisoning is high. Because of its simplicity and availability, it was easier to be performed in the primary hospital.
