1.Secreted rotein acidicand rich in cysteine and cancer research
Journal of International Oncology 2010;37(7):504-507
Secreted rotein acidicand rich in cysteine (SPARC), belonging to a family of matricellular proteins, is a multifunctional calcium-binding glycoprotein. In tumors, it functions as de-adhesion, antiproliferation, and regulation of extracellular matrix (ECM) interactions. But in different tumors,SPARC performances different biological effects, as in melanoma, breast cancer, esophageal cancer, etc, SPARC is associated with a highly aggressive tumor phenotype, while in ovarian cancer, cervical cancer, non-small cell lung cancer,SPARC may function as a tumor suppressor.

Chinese Journal of Anesthesiology 2010;30(9):1028-1029
Objective To compare the consumption of the drugs for patient-controlled intravenous analgesia (PCIA) in patients with different blood groups. Methods One hundred female ASA Ⅰ or Ⅱ patients, aged 30-50 yr, body mass index < 30 kg/m2 , scheduled for elective total hysterectomy or myomectomy, were enrolled in this study. The patients were divided into 4 groups according to the blood group: group A ( n= 25), group B ( n = 30), group AB ( n = 11 ) and group O ( n = 34). Patients received iv injection of flurbiprofen 30 min before the end of surgery and sufentanil at the end of surgery. PCIA with sufentanil 1.2 μg/ml ( bolus dose 2.0 ml, background infusion 0.5 ml/h, lockout interval 5 min) was performed when the VAS score ≤4. The loading dose and consumption on 1 st and 2nd day after operation for sufentanil were recorded. The adverse reactions were observed.Results The loading dose and consumption on 1st day after operation for sufentanil were the highest in group A and B, the second in group AB, and the lowest in group O among the 4 groups. Conclusion The consumption of the drugs for PCIA is different in patients with different blood groups.

Background and purpose:High frequency loop electrosurgical excision procedure(LEEP)has been widely used in the treatment of cervical intraepithelial neoplasia. The purpose of this study was to explore the value of loop electrosurgical excision procedure in the diagnosis and management of CINⅢ and stage ⅠAl cervical carcinoma.Methods:A retrospective analysis was carried out in 396 cases of CINⅢ and cervical carcinoma with stage ⅠAl undergoing operation and loop electrosurgical excision procedure between January 2003 and October 2006 at Obstetrics and Gynecology Hospital of Fudan University.Results:The coincidence rate of the multiple biopsies before the procedures compared with the conization ones was 88.6 % (351/395). The incidence of residual disease was 10.2%(6/59) and 7.7 % (6/78), respectively in patients with positive margins and negative margins.Conclusions:Loop electrosurgical excision procedure can improve both the diagnosis and treatment of CINⅢ and cervical carcinoma stage ⅠAl. We should offer further treatment properly to the cases with positive margin because of the persistent lesions.
6.STUDIES OF PHARMACOLOGICAL EFFECT OF KETOPROFEN
Chinese Pharmacological Bulletin 1987;0(01):-
Anti-inflammatory and analgesic and antipyretic and gastrointestinal ulcerogenic activities of ketoprofen 2-(3-benzoylphenyl -propionic acid) were investigated in experimental animals.Anti-inflammatory potency of ketoprofen was almost equal to that of indomethacin in carrageenin, yeast or nystatin-incluced hind paw edema and in acetic acid-induced increase of vascular permeability.Oral analgesic ED50-value of ketoprofen was on the whole campa-rable to that of indomethacin.Ketoprofen exerted a strong antipyretic action at oral doses in rats and its potency (ED50-1.22 mg/kg) was 2.3 times of that of indomethacin. However, ulcerogenicity of ketoprofen was weeker than that of indomethacin safety index and therapeutic index (SUD60/ED50 and LD60/ED40) of ketoprofen were greater than that of indomethacin and extremely great (the index ratio=114.7/4.5 ) in the antipyretic activity. It was suggested from these findings that ketoprofen is a potent anti-inflammatory drug with analgesic and antipyretic actions superior to indomethacin and a wide safety margin.
7.Advances on study of relation between hepatitis C virus and hepatocellular carcinoma
Academic Journal of Second Military Medical University 1981;0(04):-
It is estimated that there are about 0. 17 billion HCV infection cases worldwide. HCV sub-genotype 1b and 2a have been the most common genotypes found in the mainland China. The positive rate of HCV antigen in hepatocellular carcinoma (HCC)/corresponding non-cancer liver tissues in China is between 36. 2% (25/69)-72. 7% (48/66), which is associated with different detection methods. HCV associated HCC usually occurs along with chronic hepatitis→cirrhosis pathway. There was no doubt a correlation between the expression of HCV antigen and liver cell transformation, and the change of the functions of tumor-associated genes. These results show HCV is an important risk factor for development of HCC.
8.Effect of Mingjing decoction with argon laser on plasma VEGF in patients with diabetic retinopathy
International Eye Science 2016;16(7):1249-1252
AIM: To investigate the effect and mechanism of Mingjing decoction combining with argon laser on the levels of plasma vascular endothelial growth factor (VEGF) in patients with diabetic retinopathy(DR).
METHODS:The 66 patients(118 eyes)with DR at Ⅲ ~ Ⅴstage were randomly divided into two groups (treatment group and control group). The control group (33 patients with 56 eyes ) was treated with argon laser, and the treatment group (33 patients with 62 eyes) was treated with mingjing decoction combining with argon laser, and a blank group(30 eyes) was set up. The levels of plasma VEGF were detected by enzyme linked immunosorbent assay (ELISA). The results of best corrected visual acuity and fundus fluorescein angiography(FFA) were analyzed, as well as detected glycosylated hemoglobin ( HbA1c), blood coagulation function and the function of liver and kidney.
RESULTS: Patients with DR had significantly risen plasma VEGF before treatment when compared with blank control group ( P < 0. 05 ). After 3mo of combined treatment, the levels of plasma VEGF significantly reduced and HbA1c decreased in patients treated with mingjing decoction and argon laser, there were statistically significant difference compared to control group ( P < 0. 05 ). In the treatment group, the best corrected visual acuity and FFA were significantly improved in patients treated with mingjing decoction combining with argon laser compared to patients treated with argon laser alone after 3mo of combined treatment. CONCLUSION: Mingjing decoction combining with argon laser for DR can effectively reduce the level of plasma VEGF, stabilize blood sugar levels, improve the function of retina, and delay DR progresses.
