China Medical Equipment 2015;(4):89-91,92
Objective:To study the application value of Belinson biopsy forceps and traditional biopsy forceps in cervical intraepithelial neoplasia. Methods:Two hundred and fourty cases of cervical intraepithelial neoplasia patients received cervical biopsy under colposcopy from 2011 August to 2014 March were enrolled and randomly divided into observation group received Belinson biopsy forceps biopsy and control group received conventional biopsy forcep. Then coincidence rate between cervical biopsy and final pathological diagnosis, biopsy condition and stress levels of two groups were compared.

Serum ACTH, Cor, NE levels were lower than control group. Conclusion:Belinson biopsy forceps biopsy is helpful to improve the accuracy of diagnosis, control the degree of tissue trauma and stress reaction degree, promote cervical repair and reduce local bleeding after biopsy;it’s an ideal method in biopsy of cervical intraepithelial neoplasia.

Chinese Journal of Postgraduates of Medicine 2011;34(21):12-14
Objective To detect the effects of chemotherapy on the immune function of patients with ovarian cancer.Methods Thirty-four patients with ovarian cancer(ovarian cancer group)who accepted chemotherapy were collected.Thirty healthy women were used as control group.The lymphocyte sub-cluster CD3+,CD4+,CD8+ and CD25+of peripheral blood were detected by flow cytometry.Results The peripheral blood CD3+,CD4+ and CD4+/CD8+ in ovarian cancer group were lower than those in control group(0.5524±0.1121 vs.0.6685±0.0869,0.3183±0.0864 vs.0.4139±0.0524,1.06±0.29 vs.1.43±0.21),CD4+ CD25+was higher than that in control group(0.1026±0.0418 vs.0.0287±0.0132),there was significant difference between two groups(P<0.05).There was no significant changes observed 1 week after chemotherapy(P>0.05).Three weeks after chemotherapy,the CD3+,CD4+ and CD4+/CD8+ in ovarian cancer group were higher and CD4+ CD25+ was lower,there were significant difference between two groups(P<0.05).Conclusions The ratio of lymphocyte sub-cluster is imbalance in the patients with ovarian cancer.Chemotherapy can improve the immunosuppression condition and recovery the ratio of lymphocyte sub-cluster in the patients with ovarian cancer.
9.Effect of Fructus Ligustri Lucidi on calcium metabolism and vitamin D-dependent gene expressions in ovariectomized rats
Chinese Traditional and Herbal Drugs 1994;0(04):-
Objective To investigate the effect of Fructus Ligustri Lucidi(FLL),a kidney-tonifying Chinese herbal medicine,on calcium metabolism and vitamin D-dependent gene expression in ovariectomized(OVX) rats.Methods Four weeks after OVX surgical operation the OVX rats were ig admini-(stered) with estradiol and FLL for 14 weeks.Ca~(2+) Level in serum,urine,and feces was measured by colorimetric methods,and gene expressions in duodenum and kidney were analyzed by reversed transcriptase-polymerase chain reaction(RT-PCR).Results Ovariectomy of rat led to significant loss of calcium in vivo,as demonstrated by decreasing serum Ca~(2+) level and increasing Ca~(2+) excretion rate in urine and feces in OVX rat group.Treatment of OVX rats with FLL could effectively restore serum Ca~(2+) level and prevent the increase of Ca~(2+) excretion from urine and feces.RT-PCR Analysis showed that both estradiol and FLL could prevent OVX-induced decrease of mRNA expression in duodenal vitamin D receptor(VDR).In kidney,FLL did not alter mRNA expressions of 25-hydroxyvitamin D 1-hydroxylase(1-OHase) and 25-hydroxyvitamin D 24-hydroxylase(24-OHase),while increased the mRNA expression levels of renal cal-ciumbinding protein-9k(CaBP-9k) and calcium-binding protein-28k(CaBP-28k).Conclusion FLL could improve the state of calcium imbalance induced by estrogen deficiency and the potential mechanism that contributes to the improvement of calcium status by FLL might involve the increase in intestinal sensitivity to active vitamin D through its up-regulation of VDR expression in duodenum and the enhancement in Ca~(2+) reabsorption via the up-regulation of calcium binding proteins expression in kidney.

Methods:The expression of P-gp,MRP,LRP,GST-?,Topo-Ⅱ in 120 cases of malignant tumors were examined by immunohistochemistry stain. Results: 1. The expression of P-gp,MRP,LRP,GST-? in the 6 common cancers were relatively high,while Topo-Ⅱ was relatively low. 2. P-gp,MRP,LRP,GST-?,Topo-Ⅱ were all high expressed in hepatocellular cancer. 3. The coexpression rate of two and more genes was 95.83%,the coexpression rate of five genes was 21.67%. Conclusion:P-gp,MRP,LRP,GST-?,Topo-Ⅱ are associated with multidrug resistance in different degree,which can be regarded as valuable indicators for the decision of individual chemotherapeutic program.
