Objective Although the correlation between high risk human papilloma virus (hrHPV) infection and cervical cancer ( CC ) or cervical intraepithelial neoplasia ( CIN ) is well known , vaginal cancer ( VC ) or vaginal intraepithelial neoplasia ( VAIN) also caused by hrHPV has not received enough attention .This article aims to explore the clinical characteristics of VC or VAIN after operations of CC or CIN in order to provide evidence for the treatment of these diseases . Methods The clinical charac-teristics and treatment of 15 cases with VC or VAIN after operations of CC or CIN were reviewed from Jan 2010 to May 2013 in our hos-pital. Results The mean age was (53.6 ±10.82) years, ranged from 39 to 73 years.The duration from the first operation to devel-oped VAIN or VC was (25.07 ±18.31) months, ranged from 1 to 60 months.There are 4 cases developed VC, 4 cases VAINⅢand 2 cases VINⅡfrom 10 CC patients;and 3 cases developed VC , 2 cases VAINⅢfrom 5 CINⅢpatients.hrHPV test were positive in all 15 patients.Treatment in these series were performed including total vaginectomy in 8 patients (3 VC, 4 VAINⅢ and 1 VAINⅡpatients), pelvic lymphonectomy in 1;upper vaginectomy in 2 patients (1 VC, 1 VAINⅢ), radiation or chemo-radiation therapy in 3 (3 VC), interferon muscle injection combined with topical application of estrogen and acyclovir gel in 2 (1 VC, 1 VAINⅡ). Conclusion Careful follow-up after CC or CIN operations are very important because continued hrHPV infection may result VC and VAIN lesions.Vaginectomy may be the best therapy .Interferon muscle injection combined with topical application of estrogen and acyclovir gel are also alternatively therapy , especially for hard to operate patients . Radiation therapy seems to be not very adaptable for VAIN patients .

Objective To study the clinical significance of the serum angiopoietin-2(Ang-2) in the diagnosis,recurrence,invasion and metastasis of gastric cancer.Methods The serum Ang-2 and carcino-embryonic antigen (CEA) levels in 158 patients with gastric cancer (gastric cancer group) and 30 normal controls(control group) were measured by enzyme linked immunosorbent assay(ELISA) technique respectively.The serum Ang-2 and CEA levels were also measured 2 weeks after operation in gastric cancer group and reexamined in the recurred gastric cancer patients in 2 years after operation (recurred and metastasis group).The correlation between the serum Ang-2 level and pathologic c haracterization of gastric cancer was evaluated.Results The serum Ang-2 and CEA levels in gastric cancer group [ (331.8 ±64.3),(42.6 ±37.3)μg/L] and recurred and metastasis group [(318.7 ±72.9),(40.5 ±36.7)μg/L] were significantly higher than those in control group [ (187.4 ± 32.7),(4.2 ± 3.1 )μ g/L] (P ＜ 0.01 ),and the serum Ang-2 level 2 weeks after operation [ (211.6 ± 75.1 ) μ g/L ] was significantly decreased to the control group (P ＞ 0.05 ),while the serum CEA level [ (33.4 ± 30.6) μ g/L ] was still significantly higher than the control group (P ＜ 0.01 ).The sensitivity of the serum Ang-2 for diagnosis of gastric cancer was markedly higher than that of the serum CEA (P ＜ 0.01 ).There was correlation between serum Ang-2 and degree of tumor differentiation,TNM pathological staging,lymphatic metastasis,invasion depth and tumor size (p ＜0.01 ),but there was no correlation between serum Ang-2 and tissue classification and location of gastric cancer (P＞ 0.05).Conclusion The serum Ang-2 level is suggested to be a valuable gastric cancer marker and conduce to the diagnosis of gastric cancer,the monitoring of recurrence after operation and evaluation of prognosis.

Objective To study the characteristics of perioperative care for patients with Mitral Valve Repair (MVP) received totally robotic surgery without opening chest and provide scientific data for the clinic work. Methods The first 13 cases who received MVP with totally robotic was collected on their individual information and nursing data from their admission to discharge. Results All cases were accomplished successfully without complications. After operation 1 patient occurred Cerbral Infarction and recovery activity of extremity prior to discharge. One patient occurred thrombus of right femoral artery and take the right femoral arteriotomy embolectomy. Conclusions Totally robotic surgery with MVP is a new minimally-invasive procedure. Preoperative education is important to alleviate the patient's misgivings care. In early postoperative course, the amount of drainage should be observed and the pulmonary nursing should be carried out, especially the right lung must be stressed. The early postoperative exercise can reduce the recovery time.

Objective To investigate the preoperative psychological requirement of patients undergoing da Viric S Robotic Cardiac Surgery in order to provide scientific data for the effectively nursing interventions.Methods One hundred and six cardiac patients scheduled for Total Robotic operation were selected.They were surveyed on the first day in hospital and 2 hours before operation by self-designed questionnaire.Results Total score of the psychological requirement of patients undergoing total robotic cardiac surgery was 96 to 171 ( 137.52 ±18.54).The amount of items which necessary rate was more than 50％ was 20,they occupied 48 percent of all items.The psychological requirements of patients undergoing total robotic cardiac surgery were various,which mainly embodied in the following:wanting to know the success rate of total robotic cardiac surgery(3.70 ±0.54),wanting to understand the progress and changes of disease(3.68 ±0.51 ),wanting to understand the effect of total robotic operation(3.64 ±0.59),wanting to communicate with the patients underwent total robotic cardiac surgery (3.63 ±0.62).Conclusions The patients have many psychological requirements before to receive total robotic cardiac operation,we should take corresponding nursing countermeasures based on different psychological needs,pay attention to the patient' s health guidance and the preoperative interview in order to promote recovery.

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.

To perform a systemic review and meta-analysis of the diagnostic accuracy of PET (CT) and metaiodobenzylguanidine (MIBG) for diagnosing neuroblastoma (NB),electronic databases were searched as well as relevant references and conference proceedings.The diagnostic accuracy of MIBG and PET (CT) was calculated for NB,primary NB,and relapse/metastasis of NB based on their sensitivity,specificity,and area under the summary receiver operating characteristic curve (AUSROC) in terms of per-lesion and per-patient data.A total of 40 eligible studies comprising 1134 patients with 939 NB lesions were considered for the meta-analysis.For the staging of NB,the per-lesion AUSROC value of MIBG was lower than that of PET (CT) [0.8064±0.0414 vs.0.9366±0.0166 (P＜0.05)].The per-patient AUSROC value of MIBG and PET (CT) for the diagnosis of NB was 0.8771±0.0230 and 0.6851±0.2111,respectively.The summary sensitivity for MIBG and PET (CT) was 0.79 and 0.89,respectively.The summary specificity for MIBG and PET (CT) was 0.84 and 0.71,respectively.PET (CT) showed higher per-lesion accuracy than MIBG and might be the preferred modality for the staging of NB.On the other hand,MIBG has a comparable diagnosing performance with PET (CT) in per-patient analysis but shows a better specificity.

OBJECTIVETo explore the interaction between SerpinB5 and MAFbx in gastric cancer cell and to identify the interaction sites.

METHODSThe interaction between SerpinB5 and MAFbx was screened and validated by yeast two-hybrid screening and co-immunoprecipitation. The expression of MAFbx was analyzed after SerpinB5 expression being modified by RNA interference and pGBKT7-SerpinB5 transfection. The impact of SerpinB5 on the expression of MAFbx was studied in gastric cancer cell line SUN-16. A model of MAFbx was constructed by homology modeling. The related residues for interaction were analyzed by Autodock4.0.

RESULTSThe interaction between SerpinB5 and MAFbx was validated. The expression of MAFbx changed along with SerpinB5 expression. Amino acids including PRO261, ASN361, and LYS362 were key residue in the interaction of SerpinB5 and MAFbx.

CONCLUSIONSerpinB5 interacts with MAFbx in gastric cancer cell. Amino acids including PRO261, ASN361, and LYS362 are potential binding sites.

BACKGROUNDAdvances in minimally invasive surgical techniques and neonatal intensive care for neonates have allowed for repair of the neonatal esophageal atresia with tracheoesophageal fistula (EA/TEF) to be approached endoscopically. However, thoracoscopic surgery in children is still performed in only a few centers throughout the world. The aim of this study was to compare the neonatal tolerance to the thoracoscopic repair (TR) and the open repair (OR) and also to discuss anesthetic management in thoracoscopic procedure.

METHODSWe performed a prospective study enrolling newborns diagnosed with EA with distal TEF (type C) receiving the repair surgery between June 2009 and January 2012 in our institution. Data collected included the newborns' gestational age and weight at the time of the operation, operative time, parameters of intraoperative mechanical ventilation, oxygenation, end-tidal carbon dioxide (ETCO2), and analysis of blood gases. Time to extubation and length of stay were also recorded.

RESULTSIntravenous induction with muscle paralysis followed by pressure-control ventilation and tracheal intubation regardless of the position of the fistula can be performed uneventfully in EA/TEF newborns with no additional airway anomalies and large, pericarinal fistulas in our experiences. The thoracoscopic approach appeared to take longer than the open approach. During the procedure of repair, hypercarbia and acidosis developed immediately 1 hour after pneumothorax in both groups. CO2 insufflation did have additional influence on the respiratory function of the newborns in the TR group; values of PaCO2 and ETCO2 were higher in the TR group but the difference did not reach statistical significance. By the end of the procedure, values of PaCO2 and ETCO2 returned to the baseline levels while pH did not, but all parameters made no difference in the two groups. Besides, time to extubation was shorter in the TR group.

CONCLUSIONSThoracoscopic repair of EA/TEF is comparable to the open repair, and is believed to be safe and tolerable in selected patients. A wider range of neonates may be acceptable for thoracoscopic EA/TEF repair with increasing surgical experience.
