Objective To investigate the effect of transverse incision surgery for epicanthoplasty with double eyelid fold reconstruction. Design Retrospective case series. Participants 103 patients with epicanthus. Method Transverse incision was applied for epicanthoplasty in all patients, and incorporated with double eyelid fold reconstruction. Patients were followed up 3-6 months. Main Outcome Measures Size of lacrimal caruncle, length of palpebral fissure, inner canthic diameter and scarring degree. Results Lacrimal caruncle was revealed 3/4 merous in 21 cases, 2/3 merous in 56 cases, 1/2 merous in 8 cases. Extent of palpebral fissure was 30-31mm in 5 cases, 28-29 mm in 69 cases, 26-27 mm in 11 cases. Inner canthic diameter was 32-33mm in 61 cases, 30-31 mm in 23 cases, 29 mm in 1 case. The scarring was little in 56 cases, obviously in 29 cases. Epicanthus relapsed in 2 cases. 16 cases lost follow-up. Conclusion Transverse incision surgery for epicanthoplasty with double eyelid fold reconstruction has less tissue damage and minimal scarring produced at the medial cantha. It is a simple and reliable surgical approach for correction of epicanthus.

Objective To explore the safety and efifciency of oral iron therapy and intravenous iron therapy in anemia patients with maintenance hemodialysis,in order to gain experience for clinical treatment of this disease. Methods 88 cases collected in the ifrst people's hospital of Changshu city from July 2010 to March 2013 were divided into research group(n=44) and control group(n=44) by random number table. Control group was given oral iron therapy, and research group was t given intravenous iron. The differences of hemoglobin (Hb), reticulocyte, serum ferritin content, superoxide dismutase (SOD) and serum malondialdehyde (MDA) before and after treatment between two goups were recorded and compared. Results The differences of Hb, serum ferritin and reticulocyte numerical before treatment between two groups were not signiifcant, but signiifcant four weeks after treatment, with higher level in research group(P<0.05).The difference of oxidative stress status before treatment between two groups was not signiifcant, but after treatment, the MDA level in research group was higher than control group(P<0.05),while SOD level was lower than control group(P<0.05). Conclusion Compared with oral iron therapy, intravenous iron has better results in improving anemia, but easy to induce oxidative stress reaction.

AIM: To establish an animal model for studying the development and metastasis of melanoma. METHODS: C57BL/6 mice were used as host to receive melanoma cell transplantation. Three kinds of melanoma cell lines, B16F0, B16F1 and B16F10, cultured to prepare the cell suspensions, were transplanted into the mouse anterior chamber (AC) of the eye. The time of eyeball diabross, time of survival and metastasis of lymph node and lung were observed. RESULTS: The time of eyeball diabross in F10 group was earlier than that in other groups. The time of eyeball diabross was no difference between F0 and F1 groups. Metastasis was developed 18 days after transplantation in F1 and F10 groups, where the tumor cells was found in ipsilateral cervical lymph nodes. The melanoma cells metastasized to lung in all three groups 28 days after transplantation. The survival time in F0 group was longer than F1 and F10 groups. There was no difference in survival times between F1 and F10 group. CONCLUSION: The differences of three kinds of melanoma cell lines in tumor development and metastasis provided the evidence that was useful for choosing suitable animal model further to study the eye melanima.

Aim To investigate the effects of paclitaxel(PTX) on the expression of CD69, CD25 and proliferation of T cells by polyclonal stimulas in vitro, and explore the molecular mechanism of paclitaxel. Methods Fluorescence conjugated monoclonal antibodies and flow cytometry were used to detect the express of CD69 and CD25 by activated T cells in vitro in response to Concanavalin(Con A) and Phorbol 12,13-dibutyrate(PDB) or T cell proliferation index stained by CFDA-SE in response to PDB+Ion or Con A. Results Paclitaxel had no effect on the expression of CD69, but inhibited the expression of CD25 in activated T cells in response to Con A or PDB in a concentration-dependent manner. Paclitaxel caused a dose-dependent suppression of T cell proliferation to Con A as well as to PDB+Ion. Whether added at the beginning or after 24 h of stimulation by Con A or PDB+Ion, paclitaxel had identical effects. Conclusion The mid and later activation and proliferation of murine T cells stimulated by Con A or PDB+Ion were significantly inhibited by paclitaxel, suggesting that paclitaxel acts on the downstream signaling pathways of PKC?,and not act on the intitial activated associated proteins such as PTK and PKC?.

AIM: To study the relation between prolon ge d survival of skin allograft by chuan-ke-zhi (CKZ, drug of Chinese herbal) and C D4+CD25+ regulatory T cells (CD4+CD25+ Tr) in mice. METHODS: Skin allograft and isograft model in mice were establi shed and CKZ was administered by intraperitoneal injection. To observe its influ ence on survival of the graft, three color fluorescent staining together with fl ow cytometry was used to analyze the change of CD4+CD25+ Tr. RESULTS: The survival of skin allograft in CKZ group was signifi cantly prolonged compared to control group, (19.5?2.3) days and (10.2?2.2) days, respectively, P0.05). CONCLUSION: CKZ has an effect of prolonging the survival of skin allograft. Enhancement of CD4+CD25+ Tr might be one of the mechanisms under lying its immunosuppressive effect.

Surgical methods: in patients with malignant tumors, cervical cancer, hysterectomy plus salpingectomy or salpingo-oophorectomy for stage Ⅰa1, and radical hysterectomy plus pelvic lymphatic dissection plus salpingectomy or salpingo-oophorectomy for stage Ⅰa2-Ⅱb. Endometrial carcinoma, performed by staging surgery. Staging surgery for EOC with early stage and cytoreductive surgery with advanced EOC. Vulvar cancer, extensive vulvar resection plus inguinal lymphadenectomy. In patients with benign diseases, uterine prolapse, hysterectomy plus salpingectomy or salpingo-oophorectomy plus sacrocolpopexy. Uterine leiomyoma or adenomyosis with uterus ≥ 12 weeks, hysterectomy plus salpingectomy or salpingo-oophorectomy. Myomectomy for patients requiring uterine preservation with uterine leiomyoma. Tubal anastomosis for patients with fallopian tubal ligation. (2) Surgical complications: intraoperative complications occurred in 25 patients (2.5%, 25/1 000), including 11 patients with vascular laceration, 11 patients with ureteral injury, 2 patients with bladder injury, and 1 patient with intestinal injury. Postoperative complications occurred in 130 patients (13.0%, 130/1 000), including 66 cases of lower limb venous thrombosis, 20 cases of lymphatic cyst, 8 cases of hydronephrosis, 9 cases of ileus, 16 cases with infection, 6 cases with genital fistula, 4 cases with trocar site herniation and 1 case with subcutaneous emphysema. The incidence of intraoperative complications was 3.1% (25/811) in malignant tumors and no case in benign diseases, the incidence rate in malignant tumors was significantly higher than that in benign diseases ( χ2=4.778, P=0.029). The incidence rate in cervical cancer (4.2%, 17/405) and EOC (3.6%, 4/112) were significantly higher than those in endometrial carcinoma (1.4%, 4/279) and vulvar cancer (0/15; P<0.05). The incidence of postoperative complications was 15.2% (123/811) in malignant tumors and 3.7% (7/189) in benign diseases. The incidence rate in malignant tumors was significantly higher than that in benign diseases ( χ2=17.807, P<0.01), but there were no significant difference among different malignant tumors ( χ2=4.318, P=0.229). (3) The correlative factors affecting the occurrence of surgical complications: patient′s age, BMI, previous pelvic or abdominal surgery history, the nature of disease (malignant or benign), operation time, and comorbidities had a significant impact on the incidence of postoperative complications ( P<0.05). Multivariate logistic regression analysis showed that the patient′s age ≥40 years old, BMI ≥25 kg/m 2, previous pelvic or abdominal surgery history, malignant tumors and comorbidities were independent influential factors of the postoperative complications ( P<0.05). Conclusions:Perioperative complications vary according to the type of the surgery. The age, BMI, previous pelvic or abdominal surgery history, malignant tumors, and comorbidities are influential factors of postoperative complications.

OBJECTIVE To provide the clinical anatomy data of the lingual artery for clinical application concerning about the lingual artery. METHODS CTA examination of the carotid artery was performed in 80 adult volunteers. The 3D reconstruction images of the carotid artery with hyoid bone were obtained by using 64-slices spiral CT. At the same time, 20 extraoral dissections of the submandibular region were performed on 10 human cadavers. The origin, pathway, and anatomic relations of the lingual artery in CTA and cadavers were studied. The distance from the origin of the lingual artery to the bifurcation of the common carotid artery and tip of the greater horn of hyoid bone were separately measured, and the distance between the segment of the greater horn of hyoid bone of lingual artery and the middle of greater horn of hyoid bone were also measured. And the contrast analysis was carried on the result. RESULTS The lingual artery was mainly come from the external carotid artery (74.4 % in the CTA; 80% in the Cadavers), the next origin was come from the facial artery (23.1 % in the CTA; 20 % in the Cadavers), and it was few to found that the lingual artery had origin in the superior thyroid artery, which was 2.5 % in CTA and none in Cadavers. The path of the lingual artery had high variation, but the position between the segment of the greater horn of hyoid bone of lingual artery and the greater horn of hyoid bone had constancy relatively. The lingual artery run forward with approximation parallel to the greater horn of hyoid bone into tongue,and which located in thesuperior to the greater horn of hyoid bone (2.32?1.29 mm) or in the inferior to the greater horn of hyoid bone (2.00?1.68 mm). The distances from the origin of the lingual artery to the bifurcation of the common carotid artery and tip of the greater horn of hyoid bone in CTA and cadavers were (12.93?7.36) mm, (10.40?5.75) mmand (14.80?6.18) mm, (8.35?5.44) mm respectively. CONCLUSION The lingual artery can be show clearly in CTA and can get the anatomy data in physiological condition with CTA.

AIM: To investigate the effects of 17?-estradiol (E 2) on the maturation and immunologic function of dendritic cells from human peripheral blood. METHODS: Cultured DCs were treated with E 2 at doses of 10 -7 mol/L and 10 -6 mol/L. The morphologic changes were observed under the scanning electronic microscope. The immunophenotype of DCs in control and treated groups was analyzed by flowcytometry. IL-12 production in culture supernatant was examined by ELISA assay. The capability of the stimulatory activity of the DCs on allogeneic T cells in mixed reaction was tested by incorporation of 3H]-TdR. RESULTS: Compared with control group, DCs cultured in the presence of E 2 displayed less dendritic pseudopod, expressed low levels of MHC-II, CD40, CD80 and CD86, and exhibited weakly activity in stimulating the proliferation of allogeneic T cells and reduction of IL-12 production. CONCLUSION: E 2 exerts a negative effect on the maturation and immunologic function of dendritic cells from human peripheral blood.
