Journal of Chinese Physician 2015;17(8):1149-1152,1156
The purpose of the current study was to detect the potential therapeutic role of a survival benefit for women with advanced and recurrent endometrial carcinoma for their poor prognosis.A number of published studies for women with advanced and recurrent endometrial cancers were reviewed.We found that surgery had been the primary treatment of choice for an endometrial carcinoma.Where disease has spread to the uterine cervix,extended or radical surgery may be curative.The systematic lymph node resection improves the survival of women with intermediate/high-risk endometrioid uterine cancer,especially non-endometrioid carcinoma.The omentectomy may be beneficial for non-endometrioid cancer.A number of studies report a survival benefit from surgical cytoreduction in women with advanced and recurrent disease,although the degree of surgical effort is required in order to achieve an optimal result varies.Laparoscopic and robotic surgical staging for uterine cancer might be considered as a standard of care for endometrial cancer without extra-uterine metastasis.Laparotomy should be the first choice for extra-uterine metastasis and recurrent disease.Adjuvant radiotherapy and chemotherapy have a potential role in the management of high-risk,advanced,and recurrent disease.Efficacy of targeted and endocrinal treatment in women with advanced and recurrent endometrial cancer has been proved.

Objective To study the transfection efficiency, protein expression, and effect of adenovirus-mediated transfection on microvascular endothelial cells transfected by angiopoietin-related protein 2(Ad. ARP2)gene. Methods Mice coronary microvascular endothelial cells(CMECs) were isolated, cultured and transferred by Ad-ARP2. The transfection efficiency and cellular toxicity of adenovirus vector to CMECs were detected by immunofluorescence staining. Expression of Ad. ARP2 in CMECs and the secreted materials in culture medium were measured by Western blot and ELISA and compared among groups of Ad. ARP2, Ad. null, and PBS control. Vascular endothelial cells were incubated with conditional medium containing secreted ARP2, and effects on cells sprouting were observed in matrigel. Results Adenovirus-transfected CMECs showed a very high efficiency. When multiplicity of infection (MOD was 200, the transfection efficiency was 93. 5% ,and no harmful effect on CMECs growth was found. When CMECs were transfected with Ad. ARP2, there was a high ARP2 expression, which was significantly different from that with Ad. Null or PBS. The conditional medium containing ARP2 had an excellent ability to stimulate sprout of CMECs which phenomenon could not be seen in the control groups. Conclusions Adenovirus vector can be transferred into CMECs efficiently and safely. Ad. ARP2 gene transfection allows a high transient expression, and the expression products can stimulate the sprout of microvascular endothelial cells in vitro very well.

Purpose To investigate MRI features of encephalitis in children with severe hand-foot-mouth disease (HFMD). Materials and Methods The MR images of 85 cases of clinically diagnosed encephalitis in severe HFMD patients were retrospectively reviewed. Results In 85 patients, plain MRI was negative in 28;57 cases were positive including 10 cases showing punctate or patchy lesions in cerebral hemisphere, callosum, thalamus and cerebellar vermis with isointensity or slightly hypointensity on T1WI, isointensity or slightly hyperintensity on T2WI, and hyperintensity on T2FLAIR and DWI. In 47 cases, the lesions were located in the brainstem, tegmentum of pons and medulla oblongata. MRI features included symmetric high signal on DWI in posterior portions of brainstem, hypointensity or isointensity on T1WI and hyperintensity or isointensity on T2WI and T2FLAIR (n=17);patchy long T1, long T2 signal in posterior portions of brainstem, normal or mild hyperintensity on DWI, hyperintensity on T2FLAIR (n=30); lesion extending around the fourth ventricle in 9 patients, one of which involved bilateral cerebral peduncles. Conclusion Encephalitis in children with severe HFMD has characteristic MRI features. The lesions are mostly located in the posterior portion of the brainstem. DWI and T2FLAIR can better detection lesions.

Aim To observe the effects of the L-dopa methyl ester (LDME) on the pattern visual evoked potentials (P-VEP) and the expression of c-fos mRNA in neurons of the visual cortex of kittens with strabismic amblyopia, and explore the therapeutic effect of L-dopa methyl ester on amblyopia and its action mechanism.Methods 30 normal kittens were randomly divided into 6 groups: low dose of L-dopa methyl ester (20 mg·kg~(-1)), medium dose of L-dopa methyl ester (40 mg·kg~(-1)), and high dose of L-dopa methyl ester (80 mg·kg~(-1)),positive control (L-dopa 40 mg·kg~(-1)),normal control, and model control group.The surgery for producing iatrogenic convergent strabismus was performed on 4 weeks old kittens(normal control group excluded). After the confirmation of the development of amblyopia by pattern visual evoked potential,L-dopa methyl ester,L-dopa and normal saline were given to the corresponding animals, respectively. The P-VEP of amblyopia eyes was observed after one month, and the technique of in situ hybridization was used to detect the expression of c-fos mRNA.Results L-dopa methyl ester could reduce obviously the length of P100 peak latency of the cat strabismic amblyopes, and increase the amplitude of P100. The positive staining cells of strabismic cat visual cortex were less than those of normal cats, whose difference was significant (P<0.01).Positive staining cells in the treatment group were significantly increased when compared with that of the model group (P<0.01).Conclusion L-dopa methyl ester can significantly improve the conduction and sensory function in the model of strabismic amblyopia cats. The mechanism may be related to the increased amount of L-dopa methyl ester into the cerebral cortex and regulation of the expression of c-fos mRNA.

Objective To evaluate the feasibility and safety of a delivery pathway for the performance of percutaneous left atrial appendage (LAA) occlusion in experimental canine models. Methods Transseptal puncture was performed via femoral vein approach under fluoroscopic and angiographic guidance in 12 experimental dogs. A pigtail catheter was advanced into the left atrium (LA), which was followed by LA angiography. The diameters of the neck of LAA were measured on LAA angiogram obtained in appropriate projection. After the delivery sheath was advanced along the wire into LA, a pigtail catheter was inserted into the ostium of the LAA and the sheath was then advanced over the pigtail into the LAA. LAA angiography was then performed through the delivery sheath to confirm the position of the delivery sheath. One hour after the procedure both electrocardiography (ECG) and transthoracic echocardiography (TTE) were carried out in five dogs to check the results, immediately after which the five dogs were sacrificed to macroscopically observe the damages of the puncture site of inter-atrial septum as well as inside the LA and LAA. One hour and 2 weeks after the procedure TTE was conducted in the remaining 7 dogs and these dogs were followed up for one month. Results One dog died of pericardial tamponade during the operation. In 8 dogs the LAA was clearly displayed in the projection position of right anterior oblique (RAO) 30°/cranial (CRA) 20°,while in 3 dogs the LAA was well visualized in the projection position of RAO 30° , and in one dog in the projection position of RAO 30°/caudal (CAU) 20°. The diameter of LAA neck was (13.6 ± 5.2) mm. The delivery sheath was safely advanced into the LAA along the pigtail catheter in all dogs, and no air embolism, thrombus or pericardial tamponade occurred. Hematoma at puncture point of groin occurred in 2 dogs, which was absorbed through pressure dressing. Macroscopic examination of the heart performed immediately after the operation showed that no bloody pericardial effusion was found, and mild hematoma at posterior wall of LA was seen in one dog and mild damage of the upper-margin intima of LAA was noted in 2 dogs. The mean fluoroscopy time was (10.1 ± 2.5) minutes and the mean operation time was (58 ± 12) minutes. TEE showed no pericardial effusion 2 weeks after the procedure. During the follow-up period of one month no sudden death, stroke or infection occurred. Conclusion This method of placing the delivery sheath into the LAA is clinically safe and effective, and it can reliably establish a pathway to advance the LAA occluder into LAA.

OBJECTIVETo explore the technical feasibility, safety, and short-term clinical efficacy of right-to-lateral approach in laparoscopic-assisted radical gastrectomy.
METHODSClinicopathological data of 178 gastric cancer patients undergoing laparoscopic-assisted radical gastrectomy, including 92 patients with right-to-lateral approach(R-LG group) and 86 cases with left-to-lateral approach (L-LG group), in our department from October 2010 to September 2013 were analyzed retrospectively. Short-term efficacy and complication morbidity were compared between R-LG group and L-LG group according to body mass index (BMI).
RESULTSFor those patients with BMI ≥ 24 kg/m², the R-LG group (35 cases) had shorter mean operation time, less intraoperative blood loss, shorter painkiller used time than L-LG group (31 cases)[(227 ± 17) min vs. (262 ± 23) min, (73 ± 9) ml vs. (84 ± 8) ml and (2.1 ± 0.1) d vs. (2.6 ± 0.4) d, all P<0.05]. The average time to ambulation and recovery time of peristalsis in the R-LG group were faster than those in L-LG group [(2.2 ± 0.2) d vs. (2.8 ± 0.6) d and (3.6 ± 0.3) d vs. (4.2 ± 0.5) d, all P<0.05]. The R-LG group had more dissected lymph nodes per patient (35 ± 4) than the L-LG group (30 ± 5) with significant difference (P<0.05). There were no significances in postoperative hospital stay, postoperative complication morbidity and hospitalization expenses between R-LG and L-LG group (all P>0.05). For those patients with BMI<24 kg/m², there were no significant differences in all above parameters between R-LG group (57 cases) and L-LG group (55 cases). No mortality and recurrence was observed during follow-up of 3 to 24 months.
CONCLUSIONRight-to-lateral approach in laparoscopic-assisted radical gastrectomy is a safe and feasible procedure, especially for the obesity patients, which can shorten the operation time, decrease intraoperative blood loss, lead to a faster postoperative recovery and harvest more lymph nodes as compared to L-LG procedure.
