OBJECTIVETo observe the effect of bear bile powder (BBP) on the STAT3 pathway and its downstream target genes of nude mice hepatocellular carcinoma (HCC) xenograft, and to explore its mechanism for treating HCC.

METHODSThe subcutaneous xenograft model was established using HepG2 cells. When the subcutaneous transplanted tumor was formed, naked mice were randomly divided into two groups, the BBP group and the control group. Mice in the BBP group were administered with BBP by gastrogavage, once daily for 3 consecutive weeks, while mice in the control group were administered with normal saline by gastrogavage, once daily for 3 consecutive weeks. The body weight and the tumor volume were measured once per week. By the end of medication, the tumor weight was weighed and the tumor inhibition ratio calculated. The apoptosis of the tumor tissue was detected by TdT-mediated dUTP nick end labeling (TUNEL). The expression of Bcl2-associated X protein (Bax), B cell lymphoma/eukemina-2 (Bcl-2), cyclin-dependent protein kinase (CDK4), cyclinD1 were detected by reverse transcription-polymerase chain reaction (RT-PCR). The protein expression levels of signal transducers and transcription activators 3 (p-STAT3), proliferating cell nuclear antigen (PCNA), Bax, Bcl-2, CDK4, and cyclinD1 were determined by immunohistochemistry.

RESULTSBBP could inhibit the tumor volume and tumor weight, showing statistical difference when compared with the control group (P < 0.01). Results of TUNEL showed that BBP could significantly induce the apoptosis of hepatoma carcinoma cells. Results of RT-PCR showed that BBP could up-regulate the expression of Bax and down-regulate mRNA expression of Bcl-2, CDK4, and cyclinD1. Immunohistochemical results showed that BBP could up-regulate the expression of Bax and inhibit the protein expression of p-STAT3, PCNA, Bcl-2, CDK4, and cyclinD1.

CONCLUSIONBBP could induce the apoptosis of hepatoma carcinoma cells and inhibit their proliferation by regulating STAT3 pathway.

Objective To evaluate the method of vulvar reconstruction after extended vulvectomy. Methods Retrospectively, fourteen cases of vulva carcinoma were treated by radical wide local excision, and the defects were repaired with anterolateral thigh flap and inferior pedicle rectus abdominal myocutaneous flap. After the flap was harvested, it was put on the defect through the tunnel between the donor and the recipient site and the vulvae was reconstructed. Results All the flaps were survived except 1 anterolateral thigh flap with partial necrosis. One patient was infected at the groin incision but the flap and the grafted skin were survived. The patients were treated with change of the dressing and recovered after skin grafting. All other incisions were healed with first intention. The partial necrosis area was about 4 cm?6 cm, it healed at 36 postoperative days after free skin grafting. The reconstructed vulvae were plump and elastic. It appeared like the normal vulvae and there was no contraction of the vagina. Conclusions Vulvar reconstruction with the anterolateral thigh flap and rectus abdominal flaps after the radical vulvectomy could make the patients recover easily. It produces almost normal appearance and function of the vulvae, reduces the time of would healing. The patient could have the next therapy more quickly and the quality of life improves. It has wide application value in clinics.

OBJECTIVETo evaluate the efficacy of prophylactic transcatheter arterial chemoembolization (TACE) on postoperative recurrence of hepatocellular carcinoma.

METHODSA retrospective analysis was performed on clinicopathologic data of 260 hepatocellular carcinoma patients who underwent curative hepatectomy in Eastern Hepatobiliary Surgery Hospital, Second Military Medical University from January 2004 to June 2007. Among the 260 patients, 104 underwent postoperative prophylactic TACE and the other 156 were not.

RESULTSThe overall survival rates at 1- and 2-years were 84.1% and 70.5% respectively. The overall disease-free survival rates at 1- and 2-years were 69.2% and 58.4% respectively. Of 260 overall patients, the disease-free survival rates at 1- and 2-years were 72.8% and 54.9% respectively in TACE group, and 66.9% and 59.7% respectively in non-TACE group, statistically significant difference of the cumulative disease-free survival rates at 1- and 2-years between TACE group and non-TACE group were not observed (P = 0.145, P = 0.405). Of 62 patients with tumor size >or= 10 cm, the disease-free survival rates at 1- and 2-years were respectively 66.6% and 48.7% in TACE group, and respectively 44.6% and 31.2% years between TACE group and non-TACE group were observed (P = 0.025, P = 0.025). Of 38 patients with vascular tumor thrombi, the disease-free survival rates at 1- and 2-years were respectively 33.0% and 0 in TACE group, and respectively 26.2% and 21.8% in non-TACE group, statistically significant difference of the cumulative disease-free survival rates at 1-years between TACE group and non-TACE group was observed (P = 0.025), and not at 2-years (P = 0.122).

CONCLUSIONSIn non-TACE group, statistically significant difference of the cumulative disease-free survival rates at 1- and 2-Prophylactic TACE is preferred for hepatocellular carcinoma patients with high risk factors for recurrence such as tumor size >or= 10 cm and presented vascular tumor thrombi.

To investigate the relationship between serum retinol-binding protein 4(RBP4) and gestational diabetes mellitus (GDM) in Chinese Han pregnant women.195 (23-42 years) pregnant women were recruited (July 2005 to December 2007) from the Department of Gynecology and Obstetric in Ruijin Hospital during their visiting for routine prenatal examination.99 subjects belonged to GDM group,and 96 belonged to the group with normal glucose tolerance (NGT).65 non-pregnant healthy women served as control.Serum RBP4 was measured using sandwich enzyme linked immunosorbent assay (ELISA).Pregnant women had higher level of serum RBP4 than that of non-pregnant control.The concentration of serum RBP4 was significantly increased in GDM group as compared with NGT group[(43.04±1.85 vs 33.84±2.17) rag/L,P<0.01].Multiple stepwise regression analysis showed that triglycerides and homeostasis assessment for insulin resistance (HOMA-IR) were independent variables of RBP4 (r2 =0.165) in pregnant women.The results suggest that serum RBP4 level is significantly increased in pregnant women.Women with GDM had even higher RBP4 level than that of normal pregnant women,and RBP4 levele was positively correlated with triglycerides and HOMA-IR.

OBJECTIVESTo analyze the mood factors in prostatitis and evaluate the effects of Molida psychological therapy.

METHODSTwo hundred and thirty-six chronic prostatitis patients were divided according to the course of disease into above 6 months group (n = 31) and below 6 months group(n = 205) as well as into sexual disease group(n = 25) and non-sexual disease group(n = 211). An investigation was made by self-rating method on the basis of the National Institutes of Health Chronic Prostatitis Symptom Index(NIH-CPSI) and Symptom Checklist 90 (SCL-90) and 56 cases were rated again after Molida therapy.

RESULTS1. The scores of SCL-90 in 236 prostatitis patients were significantly higher than normal(P < 0.01). The factor scores of SCL-90 showed one-item positive in 107 patients (45.2%), of whom 27 (25.2%) had depressive disorder and 80(74.77%) had anxiety (23 with significant compulsion). Thirty-eight cases(16.1%) were two items positive. 2. The scores of SCL-90 were significantly higher in the > 6 months group of history and the sexual disease group than in the control group (P < 0.01). 3. The scores of NIH-CPSI showed a positive correlation with those of SCL-90 and both scores in 43/56 cases were significantly decreased after psychological treatment (P < 0.01).

CONCLUSIONSThe mood factor plays an important role in aggravating symptoms in chronic prostatis patients and causes difficulty for management. Molida may significantly improve the mood and symptoms of the chronic prostatitis patient.

To study the effects of Qingdai compound on proliferation and apoptosis of K562 cells, as well as the expression of bcr/abl and JWA mRNA, K562 cells were treated in culture with different concentrations of Qingdai compound (2.5, 5, 7.5, 10 and 20 mg/ml) and harvested at 24 hours. Then morphological changes were observed by light microscopy (LM); expressions of bcr/abl and JWA were detected with semi-quantitative RT-PCR. The results showed that morphological changes were observed as the increment of the Qingdai compound concentration. Inhibition effects on proliferation and apoptosis in K562 cells were seen. A concentration-dependent decreases were found in bcr-abl and JWA mRNA expression of K562 cells. Qingdai compound partially inhibited proliferation and induced apoptosis of K562 cells. Expressions of both bcr/abl and JWA, which took part in cell proliferation and apoptosis, were down-regulated in a dose dependent manner. In conclusion, Qingdai compound can partially inhibit the expressions of bcr/abl and JWA genes in K562 cells, and the clinical effect of Qingdai compound on CML may be associated with apoptosis of leukemic cells.

OBJECTIVETo explore the possibility of treating solid tumor with siCD44.

METHODSHuman nasopharyngeal carcinoma cell CNE-2L2 with high expression of CD44 was used in this study. The malignant activities of cells were examined by colony formation test, tumorigenesis, and lung metastasis of the tumor in nude mice. Ad5-siCD44 was constructed and adenoviruses were produced in 293 cells. CNE-2L2 cells were subcutaneously inoculated into nude mice. When tumors grew to 50-100 mm3, Ad5-siCD44 was injected into tumors, and Ad5-egfp and PBS were also injected as controls. The size and weight of tumors were compared after 2 weeks.

RESULTSSuppression of CD44 expression profoundly inhibited the malignant activities of CNE-2L2 cell. The average sizes of the tumors were (3.139 +/- 0.850), (3.612 +/- 0.888), and (1.512 +/- 0.742) cm3 after the intra-tumor injection of PBS, Ad5-egfp, and Ad5-siCD44, respectively, after two weeks. Significant difference was found between Ad5-siCD44 group and control groups (P < 0.05). The average weights were (2.28 +/- 0.73), (1.83 +/- 0.26), and (1.20 +/- 0.64) g, respectively, and significant difference was also found between Ad5-siCD44 group and control groups (P < 0.05).

CONCLUSIONIntra-tumor injection of Ad5-siCD44 can exhibit the therapeutic effect on the tumor inoculated with CNE-2L2 cells with high expression of CD44 in nude mice.
