Cervical cancer is one of the most common and deadliest cancers in females worldwide. Despite the treatment methods of surgery, radiotherapy and chemotherapy are maturing, the prognosis of patients with recurrent, advanced or metastatic cervical cancer remains poor. Molecular targeted therapy provides new hope for these patients. This review focuses on the advances in agents targeting vascular endothelial growth factor pathway, epidermal growth factor receptor, mammalian target of rapamycin, histone deacetylases and cyclooxygenase-2 in cervical cancer.

Objective: To investigate whether phosphorothioate-modified antisense vascular endothelial growth factor oligodeoxynucleotides ( VEGF-ASODN) formulated in cationic liposome can inhibit the blood flow of lung cancer. Methods: Lewis lung tumor models were established by subcutaneous injection of Lewis lung carcinoma cells into the right flank of 40 C57BL/6 mice. Twenty-four hours later, mice were randomly assigned into 4 groups; pure liposome, liposome containing ASODN, SODN and MODN. Mice in each group were treated twice a week for 4 weeks. Tumor growth were determined. Peak systolic flow velocity (PS) and resistance index (RI) were measured with a sonographic scanner. Expression of VEGF mRNA were detected by hybridization in situ and RT-PCR. Results: ASODN significantly suppressed the growth of subcutaneous tumors. PS and RI in VEGF-ASODN group were significantly different from those in other 3 groups ( P

Objective:The study aims to investigate whether phosphorothioate-modified antisense vascular endothelial growth factor oligodeoxynucleotides(VEGF ASODN)micro-encapsulated in cationic liposome could inhibit angiogenesis and metastasis of lung cancer.Methods:The phosphorothioate-modify VEGF ASODN, VEGF SODN(sense oligodeoxynucleotides) and VEGF MODN(mismatch oligonucleotides)micro-encapsulated in cationic liposome were added into in vitro culture of Lewis lung carcinoma(LLC ) cells,respectively. Expression of VEGF protein was detected by immunohistochemistry staining. And the inhibitory effects on bovine aortic endothelial cell proliferation by conditioned media obtained from LLC cells treated with ODN were observed. 40 mice of Lewis lung cancer models were established and subsequently were randomized into 4 groups: control group, ASODN group, SODN group,and MSODN group. Liposome, ASODN, SODN or MODN were given by twice a week for 4 weeks,respectively.The weights of subcutaneous tumors were measured. The rates of lung metastasis were detected, while the microvessel density(MVD) in tumor mass was detected by imuunohistochemistry staining. Peak systolic flow velocity(PS) and resistance index(RI) were measured with a sonographic scanner.Results:ASODN downregulated the expression of VEGF in LLC cells at the level of protein in vitro. The conditioned media obtained from LLC cells treated with ASODN significantly inhibited the proliferation of bovine aortic endothelial cells. ASODN significantly suppressed the growth of subcutaneous tumors and lung metastasis. MVD, PS and RI of VEGF ASODN group were remarkably different from those of other 3 groups(P

Purpose:To investigate the survival and prognostic factors in patients with stage Ib～IIb node-negative cervical carcinoma.Methods:From Nov.1993 to Dec. 1997,236 patients who had radical hysterectomy and pelvic lymphadenectomy and pelvic lymph node found negative were reviewed retrospectively. Survival rates were calculated by Kaplan-Meier method with differences in survival estimated by Log-rank test. Independent prognostic factors were identified by the Cox's proportional-hazards regression model. Results:The overall 5-year survival of the patients was 82.0% and the median survival time was 100.0 months. The recurrence and/or metastatic rate was 19.5%. Of these patients the 5-year survival rate was 16.9% and median survival time was 15.0 months. Among the variables,clinical stage(Ⅱb),tumor size(≥4 cm),histological type (non-squamous carcinoma),poor differentiation,deep stromal invasion,parametrial extension,vaginal margin involved,and lymphvascular permeation were the poor prognostic factors in univariate survival analysis ( P

Purpose:To detect the expression of cytokeratin 19 (CK19) mRNA and human papillomavirus type 16 (HPV16) mRNA in peripheral blood of cervical cancer patients. Methods:We used reverse transcription polymerase chain reaction (RT-PCR) to determine the expression of CK19 and HPV16 mRNA of 30 cervical cancer patients,8 patients with known distant metastases,16 patients with benign gynecological tumors and 9 healthy persons as control. Results:The presence of CK19 mRNA was observed in 3 peripheral blood samples among 30 cervical cancer patients (10%). The positive ratios for cervical patients with metastases,benign tumors and healthy control were 8/8,0/16 and 0/9. Only 10 cervical samples were proved to be HPV 16 positive by immunohistochemistry and/or hybridization in situ,whose expression of HPV16 mRNA in the peripheral blood were all negative (0/10). The positive ratios for cervical patients with metastasis,benign tumors and healthy control were 1/8,0/16 and 0/9,respectively. Conclusions:CK19 mRNA may be considered a powerful biomarker in the detection of peripheral blood of cervical cancer patients due to its high sensitivity and specificity. The detection of HPV16 mRNA was low and its clinical significance needs further evaluation.

Objective To investigate the skin basic conditions of normal female consumers for cosmetics who use a cream of lower than RMB 25 yuan in markets in Chengdu area.Methods Female subjects aged 25 to 45 years were recruited in Chengdu and divided into four age groups.Parameters were noninvasively tested to investigate skin baseline conditions of the two groups,including skin moisturization,trans-epidermal water loss (TEWL),color,texture and pH etc.Meanwhile,subjective scores were acquired by experienced dermatologists and self-questionnaires were collected to investigate subjects' concerns.Results Skin texture,softness,and skin color were found significantly different between age groups.The top 3 skin problems were dryness,skin color and wrinkles; the top 3 ideal skin were moisture,shining and fairness.Conclusions With similar environment and skin care habits,35-year-old is a turning point for females of decreased metabolism in the skin,as seen from skin color,elasticity,and roughness.

Background and purpose: Epithelial ovarian carcinoma is the most malignant tumor in female reproductive system because of its resistance to chemotherapy. Fructose-1, 6-bisphosphatase (FBP1) is a rate-limiting enzyme in gluconeogenesis used to catalyze the hydrolysis of fructose-1, 6-bisphosphate to fructose-6-phosphate and inorganic phosphate, thereby inhibiting the effect of glycolysis in tumor cells. This study aimed to investigate the association between the expression of FBP1 and chemosensitivity. Methods: The expression level of FBP1 in ovarian cancer patients was measured by immunohistochemistry. Results: According to the results of immunohistochemistry in 209 ovarian carcinoma specimens, the percentage of positive FBP1 expression was about 49.3% (103/209). Loss of FBP1 was a negative factor of survival (42.6 months vs 62.1 months, P=0.003). Besides, patients who were sensitive to chemotherapy displayed significantly higher scores of FBP1 expression than patients who were resistant to therapy (P=0.007). Conclusion: The rate-limiting enzyme FBP1 in gluconeogenesis can be used as a biomarker for predicting the chemoresistance and prognosis of ovarian cancer patients.

Objectives To evaluate the effects of hypertonic-hyperoncotic solution (HHS) on cardiac function and extravascular lung water in children after open-heart surgery for congenital cardiac disease. Methods 50 children with congenital cardiac disease were randomly assigned to 2 groups. The HHS group received HHS (7.5% sodium chloride with 6% hydroxyethyl-stareh 200 kDa). The ISS group received isotonic saline solution (ISS 0.9% sodium chloride). Cardiac index (CI), extravascular lung water index (ELWI), stroke volume index (SVI), mean arterial pressure (MAP), and systemic vascular resistance index (SVRI) were measured. Immediately after sur-gery, patients were loaded either with HHS or with ISS (4 ml/kg). Sodium concentration, osmolality, thrombocyte count(TC), fibrinogen, and arterial blood gases were detected before operation, immediately after loading, 15 minutes, 1,4, 12, and 24 hours after the end of vol-ume loading. Hemodynamic parameters were recorded at the same time. The total amount of dobutamine required was documented. Results In HHS group, MAP, SVI and CI increased, and SVRI decreased significantly after the administration of HHS, compared with ISS group and before administration(P<0.01 or 0.05). Both CVP and HR were unchanged in both groups. In HHS group, ELWI decreased signifi-cantly, compared with before volume administration. But ELWI increased directly and remained elevated for 60 minutes after the administra-tion of ISS. Sodium concentration increased immediately after infusion of HHS. The postoperative need for infused dobutamine in the patients in HHS group was decreased, compared with ISS group (P<0.05). All patients left the hospital in a clinically sufficient state. Condu-sions A single infusion of HHS after cardiac surgery is safe. After cardiopuimonary bypass surgery, the administration of HHS increased CI by elevating SVI in combination with a decreased SVRI. ELWI significantly decreased, which suggest that HHS effectively counteracts, the capillary leakage.
