Objective To observe the effects of autologous myoblast transplantation on endplate regeneration and neuromuscular function restoration following direct nerve implantation (DNI) in rats so as to offer experimental basis for the use of myoblasts in neural regeneration area and further lay foundation for the research using myoblasts as transgenic carriers. Methods A total of 20 male SD rats were randomly divided into experimental group and control group,with 10 rats in each group.Models of DNI in rat gastrocnemius were established.The experimental group was injected with primarily cultured autologous myoblasts to the DNI location,while the control group was injected with isometric medium without autologous myoblasts.The effects of myoblasts on the neuromuscular function recovery following DNI were studied by detecting the tibial functional index (FTI),neuro-electrophysiology and pathohistology.Results The experimental group displayed faster tibial nerve function recovery than the control group (P ＜ 0.01 ).The peak to peak value (PPV) of gastrocnemius neuro-electrophysiology,area under the curve and regenerated endplate number of the experimental group had statistical significances as compared with the control group ( P ＜ 0.01 ). Conclusion Myoblast autotransplantation accelerates the recoveryof neuromuscular function after rat DNI and increases the number of the regenerated endplates.

Objective To investigate the correlationbetween thecarcinoembryonic antigen ( CEA) level and hypoxic status of breast cancer, and itspotential of being a prognostic factor in breast cancer. Methods Breast cancer cell line MDA-MB-231 was cultured under hypoxic or normoxic condition to determine the protein level of CEA using Western blotting.30 breast cancer tissue sections were collected in Tianjin Medical University Cancer Institute and Hospital from April 2013 to June 2015.and were detected the expression of CEA, hypoxia-inducible factor-1α( HIF-1α) and carbonic anhydrase-9 ( CA-9 ) by immunohistochemistry.Serum CEA were detected by immunofluorescence assay of 166 breast cancer patients collected from April 2009 to June 2011.The correlation between the expression levels of CEA and breast cancer patients'clinical data was analyzed by Logistic univariate analysis.Kaplan-Meier method was employed to calculate the progression-free survival of patients with breast cancer. Log-rank test was conducted to compare the difference between groups.Results CEA levels were significantly higher in breast cancer cells under hypoxic condition in a time-dependent manner, compared to normoxiccontrol. Immunohistochemical staining indicated that CEA was coexpressed with HIF-1αand CA-9 in breast cancer and linear regression analysis revealed that CEA expression correlated with HIF-1α( P =0.0096 );Preoperative serum levels of CEA were closely related with tumor size ( P =0.015 ) andLymph node metastasis(P=0.032); CEA positive patients achieved a progression-free survival of 29.85months(versus 39.08 months in CEA negative patients, P=0.003).Conclusions Hypoxia upregulates CEA expression in breast cancer and the levels of preoperative serum CEA is a potential prognostic factor ofbreast cancer.

Esophageal cancer is one of the most common malignant tumors in China.At present, the best treatment of esophageal cancer is surgery.For the patients with cervical lymph nodes metastases, three-field lymph nodes dissection is the main solution.Ultrasonography and computed tomography (CT) of the neck play a decisive role in the preoperative examinations for patients with esophageal cancer, and should be used as routine examinations before surgery at the qualified hospital in order to improve the accuracy of preoperative assessment of cervical lymph nodes metastases of esophageal cancer and screen potential patients with esophageal cancer undergoing three-field lymph nodes dissection.

Objective To investigate the safety and clinical effect of Ⅰ-stage resection of colon cancer and synchronous liver metastasis after conversion therapy.Methods The retrospective descriptive study was adopted.The clinical data of 1 patient with sigmoid cancer with synchronous multiple liver metastases who was admitted to the Zhongshan Hospital of Fudan University in April 2013 were collected.The patient was diagnosed as sigmoid cancer with multiple lymph nodes surrounding colon and 5 metastatic lesions found in liver by preoperative imaging examination,and the maximum diameters of 2 metastatic lesions were 4.5 cm and 3.6 cm.The pathological results of colonoscopy indicated adenocarcinoma.After discussion of the multidisciplinary team,liver metastatic lesions were significantly reduced through mFOLFOX6 chemotherapy combined with bevacizumab treatment,and then patient underwent Ⅰ-stage resection of colon cancer with synchronous liver metastasis by the surgical procedures of partial hepatectomy + 3D laparoscopy-assisted radical resection of sigmoid cancer.The patient received convention treatment of antibiotic,nutrition support therapy and mFOLFOX6 adjuvant chemotherapy.The changes of lesions in liver and tumor markers were observed by tumor marker test,abdominal/pelvic CT and MRI in the upper abdomen after conversion therapy.The operation time,volume of intraoptrative blood loss,number of lymph nodes dissected and vital sign were observed in the operation.The liver function,time for out-off-bed activity,time to anal exsufflation,time of drainage tube removal,duration of hospital stay,complications,results of pathological examination and recurrence and mnetastasis of tumor were observed after operation.After discharge from hospital,the patient underwent monthly tumor marker test,B ultrasound and chest X-ray examination till January 2014 and abdominaL/pelvic CT,magnetic resonance imaging (MRI) in the upper abdomen and colonoscopy every 6 months.The follow-up of outpatient examination and telephone interview was performed to detect the recurrence and metastasis of tumor up to September 2015.Results After preoperative 4-cycle chemotherapy,the diameters of 2 metastatic lesions in liver reduced to 3.2 cm and 2.0 cm,the levels of carcinoembryonic antigen(CEA) and CA19-9 (tumor marker) were reduced to 95.9 μg/L and 252.4 kU/L.The patient underwent successful Ⅰ-stage resection of colon cancer and synohronous liver metastasis.The operation time,volume of intraoperative blood loss,numbers of lymph nodes dissected and cancerous nodes were 208 minutes,250mL,14 and 1,respectively.The patient had no blood transfusion and metastasis,with the stable vital signs and good postoperative recovery.The levels of alanine transaminase (ALT) and aspartate transaminase (AST) were 1 147 U/L and 2 631 U/L at postoperative day 1,101 U/L and 37 U/L at postoperative day 7,respectively.The out-off-bed activity,anal exsufflation,drainage tube removal and discharge from hospital were occurred at postoperative day 2,3,7 and 9,respectively.No anastomotic fistula,bleeding and infection were occurred aftcr operation.The patient was diagnosed as with ulcerated sigmoid adenocarcinoma in T3N1cM1 stage (combining with liver metastasis).The patient received adjuvant therapy of mFOLFOX6 and oral capecitabine at postoperative day 40,and was followed up for 30 months with a good quality of life and without metastasis and recurrence.Conclusion Ⅰ-stage resection of colon cancer with synohronous liver metastasis can be used for initial unresectable colon cancer with liver metastasis after conversion therapy,and it is safe and feasible,with a good therapeutic effect.

Objective To assess the value of CT in the diagnosis of PRF,and analyze the reason of misdiagnosis. Methods Retrospectively analyze the CT data of ten patients with retroperitoneal fibrosis,which were confirmed by the clinical pathology.All the patients underwent CT scan and enhanced scan.Two experienced physicians using the blind method to evaluate the location, boundary, density, invasion on the surrounding tissue and enhancement of retroperitoneal fibrosis lesions respectively.Results All patients with CT scan findings were retroperitoneal irregular-shaped soft tissue lesions,which was similar to muscle density.6 cases with surrounding the retroperitoneal vessel, 2 cases with expansion and hydrops of renal pelvis and ureter.By enhanced scan,9 cases with different degrees of enhancement,1 case without obvious enhancement.6 cases were misdiagnosed as retroperitoneal schwannoma or lymphoma. Conclusion CT can show the characteristics of retroperitoneal fibrosis. Comprehensively analyze various imaging findings is helpful for the diagnosis of retroperitoneal fibrosis. Misdiagnosis reason is mainly due to retroperitoneal fibrosis is a rare disease,and understanding of this disease in imaging findings is insufficient in the daily work.

The Many experiments show that pH affect the growth of romastigotes of L donovani. But the control tests with Acid - base scale have not been reported on the growth of promastigotes from different genesis. This paper reports that pH has different nfluence on several kinds of promastigotes from different genesis. We obseved that the growth of promastigotes of L. doncvani is inhibited when pH is 4.6 and 8.6.
