[Objective] To investigate the role of exenatide on angiogenesis in endometrial cancer Ishikawa xenografts in nude mice.[Method] We used the subcutaneous human endometrial cancer cell Ishikawa xenografts in nude mice model,and divided them into control group and exenatide-treated group.The harvested tumors were preserved for immunohistochemistry staining and western blot analysis.[Results] The micro-vessel density (CD31 positive) in exenatide-treated group was (13.2 ± 1.4)/400 power field,less than that in control group [(25.9 ± 5.8)/400 power field] (P ＜ 0.01).The expression level of VEGF was significantly lower in exenatide-treated group than that in control group (P ＜ 0.05).The mean density of tumor associated macrophages (F4/80 positive) is (31.4 ± 3.4)％ in exenatide-treated group and (72.1 ± 4.2)％ in control group with significant difference (P ＜ 0.01).[Conclusion] Exenatide weaks tumor angiogenesis within endometrial cancer Ishikawa xenografts in nude mice.

Objective: To observe the clinical efficacy of acupuncture plus navel acupuncture for patients with urinary retention after radical hysterectomy for cervical cancer. Methods: A total of 64 patients with urinary retention after radical hysterectomy for cervical cancer was divided into a navel acupuncture group (22 cases), an acupuncture group (18 cases) and an acupuncture plus navel acupuncture group (24 cases). All three groups received bladder function training and neuromuscular electrical stimulation. In addition, navel points were combined in the navel acupuncture group. Electroacupuncture was conducted to Qihai (CV 6), Zhongji (CV 3), Dahe (KI 12), Shuidao (ST 28), Ciliao (BL 32) and Huiyang (BL 35) in the acupuncture group. The acupuncture plus navel acupuncture group received both treatments. The catheter was removed after 3 d of treatment. Spontaneous urination, residual urine volume, urinary catheter dependence and recurrence after 3 d, 6 d and 9 d of treatment in each group were observed, respectively. Results: In the acupuncture plus navel acupuncture group, the markedly effective rates after 3 d, 6 d and 9 d of treatment were significantly higher than those in the navel acupuncture group and the acupuncture group; the urinary catheter dependence was lower than that of the other two groups, and the differences were statistically significant (P<0.05, P<0.01); the spontaneous urination time was shorter than that of the navel acupuncture group and the acupuncture group, and the differences were statistically significant (P<0.05, P<0.01); the residual urine volume was significantly less than that of the navel acupuncture group and the acupuncture group, and the differences were statistically significant (both P<0.01). After the catheter was removed, recurrence was observed from the next day after spontaneous urination was resumed. There were 2 cases of recurrence in the navel acupuncture group, 2 cases in the acupuncture group and 1 case in the acupuncture plus navel acupuncture group. The recurrence rate of the acupuncture plus navel acupuncture group was significantly lower than that of the navel acupuncture group and the acupuncture group (both P<0.01). Conclusion: Acupuncture plus navel acupuncture has satisfactory efficacy for urinary retention after radical hysterectomy for cervical cancer. It can significantly shorten the urinary retention time, reduce the patient's dependence on urinary catheter, and reduce the residual urine volume.

At present, the objective of cutting and pruning Cistanche deserticola is to harvest in successive years and enhance the harvesting yield and quality of C. deserticola in the process of the artificial cultivating C. deserticola. An experiment was conducted focusing on cutting and pruning C. deserticola in artificial forests of Haloxylon ammodendron drip-irrigated with saline water at the hinter-land of the Taklimakan desert, according to different growth stages and lengths. The results were following: (1) The effect of cutting on C. deserticola was similar to that of pruning, which resulted in three kinds of morphological types, not related to the bloom and size of C. deserticola. (2) The growth forms were diversified after pruning. Among them, there had sprouting new body, died or maintaining life with no sprouting, mildewed on its surface layer, etc. However, some of new bodies were sprouting from the lower part of the old body. The death rate of bloomed C. deserticola was higher than that of the underground, and the death rate of the 40 cm in stubble height for C. deserticola was higher than those with the stubble height of 20 cm and 5 cm. (3) Most of the diameter of living C. deserticola after pruning was increasing, but some of them changed little. (4) The mildew and rot of C. deserticola and the broken of the roots of the H. ammodendron and the fallen of the point of the inoculated when it was dug, which would cause the death of the C. deserticola. On the other, the yield-increasing effect and the economic benefit of the techniques of the pruning of Cistanche would need further research and evaluate. Therefore, the application of this technique needs to be cautious.

OBJECTIVETo recite early results and long-term outcomes after surgical repair of persistent truncus arteriosus (PTA).

METHODSThe clinic data of 54 patients underwent surgical repair for PTA from January 1999 to December 2009 was analyzed retrospectively. There were 36 male and 18 female patients, with a mean age of (9 ± 10) months (range, 1 to 38 months; median, 5 months). Preoperative mechanical ventilation was required in 5 patients. The surgical procedures were closure of ventricular septal defect and re-establishment of continuity between right ventricle and pulmonary artery. The right ventricular outflow tract (RVOT) was reconstructed by direct anastomosis pulmonary artery to right ventriculotomy with anterior wall patch enlargement (28 cases), or by inserting conduits (26 cases). Valvuloplasty were performed in 4 patients with truncal valves moderate to severe insufficiency and aortoplasty in 3 patients with interrupted aortic arch (IAA).

RESULTSThere were 3 patients (5.6%) died of pulmonary hypertensive crisis in hospital. The mean duration of ventilation was 6.8 days in 5 patients who were intubated before operation, while the others were 3.6 days. Forty-seven (92.2%) patients were followed-up for mean (6.8 ± 2.5) years (from 2.5 to 11.0 years). There were 2 patients with mild to moderate aortic regurgitation. One patient with aortic arch obstruction underwent balloon dilatation 2 years postoperatively. Among those patients who underwent direct anastomoses, 8 (32.0%) patients had pulmonary branch stenosis at 7 months to 1.5 years postoperatively, 12 (48.0%) patients were freedom from surgical reintervention 5.0 to 11.0 years postoperatively. Among those inserting conduits, 7 patients (31.8%) had conduit stenosis at 2.8 to 7.0 years after operation. Reoperations were performed for RVOT in 15 patients and there was no mortality.

CONCLUSIONSIt is difficult to treat the PTA patients with IAA, intra-mural coronary artery or mechanical ventilation support before operation. The technique of direct anastomosis between pulmonary artery and right ventricle offers the potential growth for RVOT, but bilateral pulmonary branch stenosis may be occurred at earlier period of postoperation in some patients.

Orthodenticlehomeobox 1 (OTX1) overexpression had previously been associated with the progression of several tumors. The present study aimed to determine the expression and role of OTX1 in human hepatocellular carcinoma (HCC). The expression level of OTX1 was examined by quantitative real-time PCR (qRT-PCR) in 10 samples of HCC and paired adjacent non-cancerous tissues, and by immunohistochemistry (IHC) analysis in 128 HCC samples and matched controls. The relationship between OTX1 expression and the clinicopathological features werealso analyzed. Furthermore, the effects of OTX1 knockdown on cell proliferation and migration were determined in HCC cell lines. Axenograft mouse model was also established to investigate the role of OTX1 in HCC tumor growth. TheqRT-PCR and IHC analyses revealed that OTX1 was significantly elevated in HCC tissues compared with the paired non-cancerous controls. Expression of OTX1 was positively correlated with nodal metastasis status (P = 0.009) and TNM staging (P = 0.001) in HCC tissues. In addition, knockdown of OTX1 by shRNA significantly inhibited the proliferation and migration, and induced cell cycle arrest in S phase in vitro. Tumor growth was markedly inhibited by OTX1 silencing in the xenograft. Moreover, OTX1 silencing was causable for the decreased phosphorylation level of ERK/MAPK signaling. In conclusion, OTX1 contributes to HCC progression possibly by regulation of ERK/MAPK pathway. OTX1 may be a novel target for molecular therapy towards HCC.

OBJECTIVETo investigate the role of donor human milk in the prevention of nosocomial infection in very low birth weight infants. MeETHODS: A total of 105 hospitalized preterm infants with a very low birth weight were enrolled. They were classified into mother's own milk feeding group, donor human milk feeding group, and preterm formula feeding group, with 35 infants in each group. The three groups were compared in terms of incidence rates of nosocomial infection, necrotizing enterocolitis, and feeding intolerance, time to full enteral feeding, and early growth indices.

RESULTSCompared with the preterm formula feeding group, the donor human milk feeding group and the mother's own milk feeding group had significantly lower incidence rates of nosocomial infection and necrotizing enterocolitis and shorter time to full enteral feeding (P<0.05). There were no significant differences in head circumference, body length, and weight growth velocity among the three groups.

CONCLUSIONSDonor human milk can be used in case of a lack of mother's own milk and may help to reduce nosocomial infection.

OBJECTIVETo analyze the experience of treatment strategies for pediatric patients with primary cardiac tumors.

METHODSThe clinical data of 27 patients with primary cardiac tumors which detected by echocardiography from May 1999 to May 2009 was analyzed retrospectively. There were 20 male and 7 female patients, aged from 24 d to 12.6 years. There were 59.2% less than 1 year old at the time of diagnosis. A single tumor were present in 22 cases and multiple in 5 cases. Surgery was performed for 22 patients due to the varied significant symptoms such as arrhythmia, pericardial effusion, swoon and congestive heart failure with dyspnoea. Five patients were discharged hospital without surgical treatment. The surgical approaches were adopted according to tumor location. Complete surgical resection was performed in 14 patients and partial resection in 8 patients. Seven patients were underwent valve reconstruction, 5 involving the mitral valve and 2 involving the tricuspid valve.

RESULTSHistologic examination of the surgically resected tumors showed rhabdomyomas in 8 cases, fibromas in 5 cases, hemangiomas 3 cases, myxomas in 4 cases, fibrosarcoma in 1 case and yolk sac sarcoma in 1 case. Sixteen cases revealed stable haemodynamic status postoperative. Two cases occurred apparent symptoms of low cardiac output and significant arrhythmias, finally recovery after comprehensive treatment of restoration the heart function. There was a total of 4 patients in-hospital death following surgery due to multiorgan system failure. Of the 18 patients who survived after the surgery were followed up from 1 to 10 years, echocardiography showed the residual mass of the tumor with partial resection, rhabdomyoma diminishing in 2 patients and almost vanishing in 1 patient. The residual mass of one fibrosarcoma patient and one hemangioma patient were not increased. Patients with myxomas had no recur or systemic embolisation after the initial surgery. Five nonsurgical patients were followed up from 1 to 3 years, 2 patients without haemodynamic alterations, 1 patients with giant tumor of left ventricular free wall was died of arrhythmia, the other one was alive; the patient of multiple cardiac tumor with low cardiac output was died of heart failure.

CONCLUSIONSDespite the benign histology of most paediatric primary cardiac tumours, there may be significant associated with morbidity and occasional mortality. Therapy strategies should be individualised: surgery is indicated in cases with significant clinical symptoms and close follow-up is necessary for asymptomatic patients. Total resection is not the only therapeutic aim. Most important is the restoration of the normal haemodynamic heart function.
