BACKGROUND: Scholars disagree with each other about the small saphenous vein effects on skin flap and how to dispose vascular proximal pedicles.OBJECTIVE: To analyze effects of different methods of the small saphenous vein disposal on flap survival using sural neurocutaneous island flap retrograde metastasis for repairing defects of soft tissue of instep, heelstick and ankle.DESIGN, TIME AND SETTING: The case control observation experiment was performed at the General Hospital of Guangzhou Military Area Command of Chinese PLA from March 1998 to April 2007.PARTICIPANTS: A total of 56 patients with defects of soft tissue of instep, heelstick and ankle were divided into 2 groups,small sapbenous vein deligation in proximal pedicle flap group (group A) (n=38), and proximal small saphenous vein and great saphenous vein or tributaries at recipient site anastomosis flap group (group B) (n=18).METHODS: During sural neurocutaneous island flap retrograde metastasis for repair,(3.5×4.0)cm-(4.0×4.5) cm flap was obtained in 35 cases, and (4.0×4.5) cm -(10.0×12.0) cm in 21 cases.MAIN OUTCOME MEASURES: Outcome of flap survival at different incision area and implanted methods.RESULTS: No vein articulo occurred in 21 cases, which flap areas were (4.0×4.5) cm -(10.0×12.0) cm. Five of 35 cases which flap areas were (3.5×4.0) cm -(4.0×4.5) cm developed vein articulo.The necrotic rate of flaps in group B was significantly lower compared to the group A (P=0.017 67).CONCLUSION: When the area of skin flap is smaller than (4.0×4.5) cm, the proximal end of the small saphenous vein should be anastomosed with the great saphenous vein or tributaries connecting with the great saphenous vein at recipient site.The small saphenous vein is not a superficial vein, which only cross the skin flap, but it has trophic action on the skin flap.

Objective To investigate the effects of dexmedetomidine on hemodynamics and tra-cheal intubation facility in general anesthetized patients.Methods Forty gynecological patients of se-lective operation under general anesthesia were randomly arranged into 2 groups:group D and group C.With high flow mask oxygen inhalation(5 L/min),dexmedetomidine was intravenously pumped in-to the patients in group D at 0.6μg/kg in 10 minutes while in group C saline were given instead.Both groups were then proceeded with rapid sequence induction (RSI)immediately.The values of MAP, HR,PaO2 and PaCO2 were recorded every minute from pumping start till 15 minutes,the bucking, intubation time and glottis exposure were evaluated as well.Results No significant differences were found in intubation time or glottis exposure between these two groups.After tracheal intubation group D showed higher MAP value than group C at 14,15 minutes,and a lower HR value (P <0.05).Even no significant differences were found in values of SpO2 and PaO2 ,the group D showed less bucking than the group C (P<0.05).Conclusion Dexmedetomidine administration at 0.6μg/kg in RSI can diminish the variation in hemodynamics and facilitate the tracheal intubation by less buc-king,but no affect the oxygen reserve.

Objective To explore the effect of proprioceptive neuromuscular facilitation (PNF) on balance function of stroke patients in community. Methods 204 stroke patients in community were divided into control group (n=98) and observation group (n=106). The control group accepted routine rehabilitation and the observation group received PNF additionally. Fugl-Meyer Assessment of lower extremities (FMA), Berg Balance Scale (BBS) and static balance locator were used to evaluate the motor and balance function before and 3 months after treatment. Results The scores of FMA and BBS were higher after treatment than before (P<0.05) in both groups, and were higher in observation group than in control group (P<0.05). The length of path (L), covered area (A) and L/A were less in observation than in control group (P<0.05) both in the eye-open and eye-closed modes. Conclusion PNF can improve the lower extremities motor and balance function of stroke patients in community.

ObjectiveTo find out the inhibitory effects of CD4 - CD8 - DNT cells on growth of which depresses the pancreatic cancer in vitro and in vivo.Methods The inhibitory effects of DNT cells on the growth of Panc- 1 were studied in vitro by MTT method.Eighteen BALB/c mice were divided into 3 groups randomly.Human pancreatic cancer xenografts were established in 2 groups randomly.The last group was injected the cell suspension which comprises DNT and Panc- 1 cells ( Panc- 1∶ DNT =1∶ 5 ).When the diameter of tumor was about 5 mm,the first 2 group mice were further divided into 2 groups randomly.One was control,treated with distilled water.The other was treated with celebrex (4 mg/d).The size of the tumors was calculated every 2 weeks and tumor growth curve was depicted.At the end of the treatments,the mice were sacrific and the tumors were harvested.The tumor inhibition rate was calculated.Results( 1 ) MTT study showed that DNT cells produced a dose- dependent inhibition of Panc- 1 proliferation in vitro.(2) The growth of transplanted pancreatic cancer was down-regulated by treatment of DNT cells.ConclusionDNT cells can inhibit the growth of pancreatic cancer in vitro and in vivo.

Pancreatic cancer is a commonly malignant gastrointestinal tumor with an significantly increasing incidence.Those patients without nonspecific symptoms at early stage had mostly lost the opportunity of surgical therapy when pancreatic cancer was detected at advanced stage,and its prognosis is poor.Therefore,it is rather important to improve the early diagnosis of pancreatic cancer.In recent years,proteomics is developing rapidly.Proteomics technologies have been widely used in clinical research.Using proteomics technology screening pancreatic cancer tumor markers becomes the research focus,thus we try to find a kind of or a group of pancreatic tumor markers,so as to improve the diagnosis of pancreatic cancer.

ObjectiveA comparative proteomic method was used to analyse serum proteins between pancreatic cancer patients and control group,and to find a new protential specific marker.MethodsComparative analysis on the pancreatic peripheral blood protein profiling from 40 pancreatic cancer patients,10 chronic pancreatitis patients,10 benign tumor patients and 40 cancer-free controls was carried out by 2D differential gel electrophoresis,and differentially expressed proteins were identified by matrix-assisted laser desorption/ionization time of flight mass spectrometry.ResultsTwo differentially expressed proteins:transthyretin and apolipoprotein E were identified.Those proteins were highly expressed in pancreatic carcinoma group compared with normal control group,chronic pancreatitis group and benign tumor group.Conclusion2D differential gel electrophoresis and matrix-assisted laser desorption/ionization time of flight mass spectrometry technology in screening specific serum biomarkers of pancreatic cancer has a well repeatability and stability.The identified protein transthyretin in this study may be as specific serum biomarkers of pancreatic carcinoma.

4-coumarate coenzyme A ligase is a key enzyme of phenylpropanoid metabolic pathway in higher plant and may regulate the biosynthesis of ferulic acid in Angelica sinensis. In this study, the homology-based cloning and rapid amplification of cDNA ends (RACE) technique were used to clone a full length cDNA encoding 4-coumarate coenzyme A ligase gene (4CL), and then qRT-PCR was taken for analyzing 4CL gene expression levels in the root, stem and root tissue at different growth stages of seedlings of A. sinensis. The results showed that a full-length 4CL cDNA (1,815 bp) was obtained (GenBank accession number: KT880508) which shares an open reading frame (ORF) of 1 632 bp, encodes 544 amino acid polypeptides. We found 4CL gene was expressed in all tissues including leaf, stem and root of seedlings of A. sinensis. The expressions in the leave and stem were increased significantly with the growth of seedlings of A. sinensis (P < 0.05), while it in the root showed little change. It indicates a time-space pattern of 4CL gene expression in seedlings of A. sinensis. These findings will be useful for establishing an experiment basis for studying the structure and function of 4CL gene and elucidating mechanism of ferulic acid biosynthesis and space-time regulation in A. sinensis.

Objective To evaluate the applications of magnetic resonance cholangiopancreatography (MRCP) after fat meal in the preoperative evaluation of biliary anatomy of living liver donors.Methods Fifty cases of the preoperative donors for living liver transplantation were included and all had the corresponding intraoperative cholangiography (IOC) information. The MRCP of the donors for living liver transplantation was performed before and after fat meal (two fried eggs). The visualization and diameter of the secondary bile duct were analyzed before and after the fat meal. The results of the biliary branching pattern by MRCP after fat meal were compared with the corresponding IOC results. The accuracy, sensitivity,specificity, positive predictive value and negative predictive value of MRCP after the fat meal in distinguishing normal and any type of variant biliary anatomy were calculated. Results In all cases,82% of the 50 cases in MRCP before the fat meal could meet the diagnosis needs of the preoperative evaluation,and 100% of the 50 cases in MRCP after the fat meal could meet the diagnosis needs. There was significant difference in the demonstration quality and diameter of the secondary bile duct in MRCP before and after the fat meal (P＜0. 05). MRCP showed accurate anatomy of the biliary system, using IOC as the reference standard, in 49(98%) subjects. The sensitivity, specificity, positive predictive value and negative predictive value of MRC in distinguishing normal and any type of variant biliary anatomy were 98%,94. 7%, 100%, 10% and 96. 9%,respectively. Conclusion The MRCP after fat meal can clearly demonstrate the secondary bile duct and perfectly meet the needs of the preoperative evaluation of the living liver transplantation. The MRCP after fat meal and routine MRCP should be considered complementary to one another in order to avoid complications in living liver transplantation donors.
