0.05). But in repeated chemotherapy, the period of leukopenia recovered to normal was shorter in group B than that in group A or group C. The effects of the domestic rhG-CSF on leu-copenia induced by chemotherapy were similar to the imported products of same dose. CONCLUSION: Low dose of domestic rhG-CSF (75?g) can effectively treat the leukopenia caused by postchemotherapy in patients with gynecological tumors. 150?g of domestic rhG-CSF is more effective than 75?g of domestic or import rhG-CSF in treating leukopenia in repeated chemotherapy.

The genes amplified in breast cancer family,as the novel defined hormone receptor co-activators,of which the key number is amplified in breast(AIB) 1,is critical to the transcriptional activation function of nuclear hormone receptors.The abnormal expression of protein is related to the tumorigenesis and development of many tumors.Recently,emerging evidence suggests that the member of AIB family expresses abnormally and amplifies in ovarian tumors.Collectively,these results suggest that the AIB family is involved in the carcinogenesis and the development of ovarian cancers.Further research is required to explore the mechanism and significance as well as to determine the role of AIB family in ovarian cancers,which will potentially leading to a new prognostic marker and new therapeutic targets.

Objective To explore the prognostic factors of endometrial carcinoma.Methods 166 patients with endometrial carcinoma in Cancer Hospital of Shantou University Medical College from May 1996 to June 2009 were analyzed retrospectively.Prognostic factors were analyzed by univariate analysis.Results The total 5-year survival rate of 166 cases was 86.7 ％.The univariate analysis showed that the age,deep myometrial invasion,lymph-node metastasis and operative-pathological staging were significantly associated with the prognosis (P ＜ 0.05).As well as,according to muhivariate Cox proportional-hazard model,3 independent factors as the age,deep myometrial invasion and lymph-node metastasis were related significantly to overall survival (P ＜ 0.05).Conclusions The 5-year survival rate of endometrial carcinoma is high.The age,deep myometrial invasion and lymph-node metastasis are independent prognostic factors of endometrial carcinoma.

Objective To investigate the clinical characteristics and prognosis of young patients with endometrial cancer. Methods Eighty-two cases with endometrial cancer were analyzed retrospectively,31 cases in the young group were ≤ 45 years old, and 51 cases in the old group were ＞ 45 years old. The clinical characteristics, diagnosis, treatment and prognosis between the two groups were compared. Results Twelve cases with primary infertility took up 38.7% in the young group,23 cases with less than 3 times of pregnancy occupied 74.2%, and there was no statistical difference,compared with the old group [3.9%(2/51)and 29.4% (15/51)] (P＜0.05). There was statistically significant between the two groups in myometrial invasion (P ＜ 0.05 ); while there was no significance between the two groups in pathological type, histological grade,clinical stage, 5-year survival rate and recurrence period (P＞0.05). Conclusion Infertility or less pregnancy are risk factors for endometrial cancer in the young; the degree of endometrial invasion in the young is more shallow than that in the old; there is no significant difference between the young and the old in pathological type, histological grade and clinical stage; but the prognosis is similar between the young and the old patients.

Objective To explore prognostic factors of the uterine papillary serous carcinoma (UPSC).Methods Twenty eight patients with UPSC in Cancer Hospital of Shantou University Medical College from January 2002 to August 2013 were analyzed retrospectively.Prognostic factors were analyzed by univariate analysis.Results Twenty eight cases of UPSC with 6.3％ occurrence in the endometrial carcinoma admitted in the same period,including 14 cases of staging Ⅰ ～ Ⅱ,and 14 cases of staging Ⅲ.The univariate analysis showed that lymph-node metastasis and operative-pathological staging were significantly associated with the prognosis (P ＜ 0.05),but were not associated with the menopausal,postoperative treatment,operation style,deep myometrial invasion,cervical involvement,and annex invasion (P ＞ 0.05).Two cases of Ia-staging without myometrial infiltration and without added postoperative treatment were still alive.Conclusions Operative-pathological staging and retroperitoneal lymphadenectomy were independently prognostic factors of UPSC.The Ia-staging without myometrial infiltration might be without added postoperative treatment.

Purpose:To evaluate the therapeutic effect of paclitaxel and platinum containing chemotherapy (cisplatin or carboplatin) in women with epithelial ovarian cancer.Methods:We assigned 16 cases with advanced epithelial ovarian cancer after initial surgery to receive paclitaxel and cisplatin or carboplatin. Pcalitaxel (135 mg/m 2,over a period of 10 hours ) was administered iv once every 3 to 4 weeks, 24 control cases were treated with "CAP" or "CVP" regimen. Results:The overall median survival was significantly longer in the paclitaxel platinum group than in the cisplatin cyclophosphamide group (median, 35 vs. 22.5 months, P

Objective To explore the value of serum CA125 level to the prognosis of epithelial ovarian cancer.Methods The clinicopathologic data and serum CA125 level of 76 patients with epithelial ovarian cancer from Jan.2003 to Dec.2009 were analyzed retrospectively, and the outcomes of patients were followed up.Results No relationship was found between CA125 concentration before therapy with prognosis and cytoreductive condition for epithelial ovarian cancer.The normal or abnormal CA125 concentration after 3 courses of treatment meant different prognosis, with the 5-year survival rates of 63.8 ％ and 25.0 ％, and the median survival time of 57 months and 28 months, respectively (x2 =19.951, P =0.000).The 5-year survival rates of patients with CA125 concentration≤ 10.0 U/ml and＞10.0 U/ml after therapy were 72.7 ％ and 42.8 ％, respectively (x2 =7.266, P =0.007).According to multivariate Cox proportional-hazard model, two independent factors , operative pathological staging and CA125 concentration after 3 courses, were related significantly to the prognosis of epithelial ovarian cancer (P ＜ 0.05).Conclusion Serum CA125 level, especially after 3 courses and therapy, plays an important role in the prognosis of epithelial ovarian cancer.

Objective To evaluate clinical efficacy and survival outcomes of neoadjuvant treatment on early stage bulky cervical carcinoma.Methods A total of 155 cases with bulky stage Ⅰ b2 or Ⅱ a2 cervical carcinoma in Affiliated Tumor Hospital of Shantou University Medical College from Nov.2010 to Feb.2015 was reviewed and divided into two groups according to pre-operative treatment 108 cases in the neoadjuvant treatment group and 47 cases in the control group who underwent radical surgery directly.The clinical,pathologic,and follow-up data were analyzed retrospectively.Results The total response rate of neoadjuvant treatment was 75.0％.Histological grade in neoadjuvant treatment group was better than the other group and the rate of deep myometrial infiltration was tend to low in neoadjuvant treatment group.There was no difference in pathological type,parametrial involvement,lymph node metastasis,and lymph vascular space invasion between two groups.The rate of postoperative treatment was similar (92.6％ vs 87.2％,P ＞ 0.05).The overall survival rate of neoadjuvant treatment group was 96.4％ and the other group was 88.9％ (P =0.069).Conclusions Neoadjuvant treatment was effective for early stage bulky cervical carcinoma.It might reduce tumor histological grade and maybe improve the overall survival of patients.

Objective To explore the therapeutic effects and mechanisms of umbilical cord mesenchymal stem cells(UC-MSCs)implantation on knee osteoarthritis(OA)in rabbits. Methods The healthy adult New Zealand rabbits were divided into control group(n=4),OA model group(n=4),and treatment group(n= 4).OA model was induced by 4% papain injection(0.1 ml/kg for 2 times),and treatment group were treated with UC-MSCs implantation(1 ml,1×105/L).At 2 weeks after papain injection for preparation of osteoarthritis model,rabbits knee joints were examined by MRI,and synchrony serum levels of IL-6 and-8,MMP-3 and-13 were tested.At 3 weeks after papain injection for OA,1×106/L 1 ml UC-MSCs were injected into articular cavity in treatment group,and normal saline was injected into articular cavity in blank control group and OA model group.At 2 weeks and 4 weeks after the treatment,serum levels of IL-6 and IL-8,MMP-3 and MMP-13 were tested respectively.At 4 weeks after the treatment,knee joints were reexamined again by MRI.After this,the rabbits were sacrificed and synovium and articular cartilage were taken out for HE and immunohistochemistry examination.Serum levels of IL-6 and IL-8,MMP-3 and MMP-13 were tested by ELISA method. Results The levels of inflammatory cytokines such as IL-6,IL-8,MMP-3,MMP-13 were significantly higher in model group 〔(44.7 ± 14.5)μg/L,(7.6 ± 2.5)μg/L,(16.5 ± 4.3)μg/L,(4.50 ± 1.20)μg/L〕and in treatment group 〔(43.9 ± 15.2)μg/L,(9.8 ± 2.9μg/L),(18.3 ± 4.9) μg/L,(4.80 ± 1.80)μg/L〕than in control group〔(20.8 ± 11.2)μg/L,(1.2 ± 0.6)μg/L,(2.8 ± 0.9) μg/L,(0.02 ± 0.02)μg/L〕(all P < 0.05).The levels of IL-6,IL-8,MMP-3,MMP-13 were significantly lower after UC-MSCs treatment〔(23.8 ± 11.4)μg/L,(2.4 ± 1.3)μg/L,(10.5 ± 3.4)μg/L,(0.50 ± 0.20)μg/L〕than before treatment(all P<0.05).Based on magnetic resonance imaging,the treatment group versus model group showed an improved coarse cartilage surface,thickened subchondral bone and synovium,and decreased volume of joints effusion.Pathological finding showed lower levels of inflammatory reaction in cartilage and synovium in the treatment group versus model group.Immunohistochemistry showed lower levels of IL-6 and MMP-13(all P<0.05). Conclusions The inflammatory response of cartilage and synovial tissue induces OA progress,and the inflammation factors play a significant role in OA progress.UC-MSCs could protect cartilage and synovial membrane of joints and inhibit the inflammatory response.Therefore,this study provides new therapy method for OA.
