Objective To develop the clinical application and the method for functional repair in fa- cial nerve defect in parotideetomy of parotid carainoma.Methods Defect of facial nerve in parotidectomy was repaired by transplantation of sternocleidomastoid muscle-great auricular nerve flap with anastomosis of great auricular nerve-facial nerve under microscope.Results Eight eases of facial nerve defect in parotid carcinoma were repaired by this method.The facial nerve function almost recovered and access to normal dur- ing 3 to 6 month after operation in this series.6 of 8 patients achieved a gradeⅡ,2 of 8 patients achieved a gradeⅢ.Conclusion Reconstruction of facial nerve defect using sternocleidomastoid muscle-great auricu- lar nerve flap can provide better blood supply for the plerosis and regeneration of nerve.The nerve flap also ac- celerate the functional recovery after nerve grafting.
4. Construction of mouse wide-type and mutant dynactin-1 vectors and their expression in mouse podocytes
Academic Journal of Second Military Medical University 2012;33(7):780-784
Objective To construct mouse wide-type and mutant dynactin-1 expression vectors and investigate their expression in mouse podocytes. Methods Mouse cDNA was synthesized from mouse total RNA and was used as a template for PCR amplification to obtain full length dynactin-1 cDNA. The DNA fragment was then cloned into pcDNA3. l(+)-FLAG and pEGFP-Nl vector to produce wide-type dynactin-1 vector. The mutant dynactin-1 was obtained by site-direct mutagenesis kit. All the constructs were verified by restriction enzyme digestion, sequenced, and then transfected into mouse podocyte clone 5 (MPC5). Western blotting analysis and immunofluorescence microscopy were employed to determine dynactin-1 protein expression. Results The amplified mouse dynactin-1 cDNA fragment was analyzed by agarose gel electrophoresis and a single discrete band of the correct size (3. 8 kb) was observed. The vectors containing mouse dynactin-1 were subjected to restriction enzyme digestion and two vector fragments (pcDNA3. l[+]-FLAG(5. 4 kb) and pEGFP-Nl[4. 7 kb] individually) and the 3. 8 kb insert fragment were observed by electrophoresis. The result of sequencing showed that the sequence of cloned dynactin-1 was identical to that reported in Genbank. Dynactin-1 protein band with the correct relative molecular weight was detected by Western blotting analysis, and immunofluorescence microscopy showed dynactin-1 protein expression in the cytoplasm of the mouse podocytes. Conclusion We have successfully constructed wide type and mutant dynactin-1 vectors expressed them in mouse podocytes.

Objective To explore the influence of feeding styles in early stage on children′s weight in different stages.Methods A complete record of 918 healthy infants was selected and then divided into 3 feeding groups:breast feeding, mixed feeding and artificial fee-ding, according to the way of feeding in the first 6 months after birth. Their weights and heights were measured in the 3rd,5th,8th,12th,18th,24th,60th month to conduct the Z score of weight for age (WAZ), weight for height (WHZ) and the body mass index (BMI) of 60-month-old infants.An investigation on the time of adding auxiliary food was conducted.Results The heavier,WAZ and WHZ of breast feeding group in the 3rd month were higher than the other groups,and the differences were statistially significant(F=4.12, 5.66, 5.79 Pa

Objective To investigate the inhibitory effect of paclitaxel on rat graft arteriosclero- sis and the mechanism.Methods The rat abdominal aortic allograft model was used.All rats were divided into three groups:isograft control group (Wistar to Wistar),allograft group (Wistar to SD) and allograft paclitaxel-treated group (Wistar to SD).Rats in allograft paclitaxel-treated group re- ceived paclitaxel (2 mg?kg~(-1)?d~(-1)) from the operation day to post-operative day 14 and others received same dosage of vehicle (0.9% normal saline).Animals were sacrificed and the grafts were harvested at 30th day after operation.Intimal proliferation was studied by light microscopy.The apoptosis of vascular smooth muscle cells (VSMCs) was detected by transmission electronic microscopy and termi- nal deoxynucleotidyl transferase biotin nick end-labeling (TUNEL) method.Results Morphological analysis showed that grafts had no change after operation in isograft control group,but in allograft group intimal proliferation,inflammatory cells infiltration in neointima and adventitia and stenosis of allografts were obvious.After treatment with paclitaxel,there was a significant decrease in intimal proliferation,inflammatory cells infiltration and stenosis.Apoptosis index of VSMCs was higher in the allograft paclitaxel-treated group than other groups.Conclusion Paclitaxel can inhibit intimal pro- liferation in aortic allografts and prevent the graft from arteriosclerosis possibly by inducing the apoptosis of VSMCs.

Objective To compare the effects on neurobiological factors of attributional retraining group therapy (ARGT) or selective serotonin reuptake inhibitors (SSRI) for major depressive disorder (MDD),anxiety disorder (AD) and obsessive-compulsive disorder (OCD).Methods Outpatients with MDD,AD and OCD were divided into ARGT group (n =63) and SSRI group (n =66) according to the sequence of entering the study.MDD,AD and OCD patients were respectively measured with Hamilton Depression Scale (HAMD),Hamilton Anxiety Scale (HAMA),and Yale-Brown Obsessive Compulsive Scale (Y-BOCS) before and after 8 weeks treatment.All subjects were detected of plasma serotonin,norepinephrine,cortisol and adrenocorticotropic hormone by radioimmunoassay before and after treatment.Results After treatment,HAMD scores of MDD patients were reduced significantly in both ARGT group (t =18.411,P =0.000) and SSRI group (t =20.092,P =0.000) ; HAMA scores of GAD patients were reduced significantly in both ARGT group (t =13.989,P=0.000) and SSRI group (t=15.815,P=0.000) ;Y-BOCS scores of OCD patients were reduced significantly in both ARGT group (t =5.465,P =0.000)and SSRI group (t =4.792,P =0.000).In ARGT group,MDD (t =3.145,P =0.006),AD (t =2.785,P =0.012) and OCD patients (t =2.877,P =0.011) decreased plasma cortisol concentrations significantly.In SSRI group,MDD (t =-2.923,P =0.010) and OCD patients (t =-2.301,P =0.035) improved plasma serotonin significantly and MDD patients (t =-2.333,P =0.033) improved plasma norepinephrine significantly.Conclusion ARGT can modulate plasma cortisol level.SSRI can up-modulate plasma serotonin level.The two therapies take effect by different biological ways.

Objective To discuss the application value of 18F-FDG PET/CT in diagnosis of colorectal cancer. Methods We retrospectively analyzed the data of 186 patients who were diagnosed as colorectal cancer by 18F-FDG PET/CT. We classifed all cases according PET/CT imaging into position group and type group,and calculated SUV (maximum standard uptake value) of tumor tissue, and compared with normal tissue. Results There were 112 cases of rectal cancer,27 cases of carcinoma of sigmoid, 17 cases of carcinoma of cecum,16 cases of ascending colon carcinoma,14 cases of carcinoma of descending colon according to positions via PET/CT. There were 68 cases of protrude type,57 cases of ulcerative type,34 cases of infiltrating type,27 cases of colloid adenoma according types via PET/CT. The SUV of tumor tissue was higher than normal value,the difference had statistical significance. Conclusion 18F-FDG PET/CT has high application value in colorectal cancer diagnosis, positions and types.
