Objective:To explore the preventive function for sweating gustatory syndrome and esthetic effect of restoring parotid gland area defect by using platysma flap. Methods: Nine patients who underwent parotidectomy and restored parotid gland area defect with platysma flap were analyzed retrospectively in this study. Observed whether there was an incidence of subjective sweating gustatory syndrome and introcession in the operation region. Results: There was no incidence of subjective sweating gustatory syndrome. Moreover, introcession in the operation region was not obvious. Conclusion: Restoring parotid defects with platysma flap can reduce introcession in the operation region. Application of platysma flap as an interpositional barrier between the skin flap and the parotid bed after parotidectomy can reduce the incidence of sweating gustatory syndrome.

BACKGROUND:Once lumbar degenerative diseases merge with lumbar spinal stenosis, lumbar instability and degenerative scoliosis, surgical therapy is required for corresponding clinical symptoms, and the usage of internal fixators cannot be inevitable. Osteoporosis is rather common in the elderly. Therefore, how to implant stable pedicle screw fixation system in serious osteoporosis patients wil be a big difficulty. In recent years, some studies have proven the biomechanical stability of polymethylmethacrylate augmentation of a cannulated and fenestrated pedicle screw in the vertebral body, so it becomes very hot in the spine surgery. OBJECTIVE: To explore the clinical efficacy of the use of polymethylmethacrylate augmentation of a cannulated and fenestrated pedicle screw fixation for the treatment of lumbar degenerative disease accompanied with osteoporosis. METHODS:Thirty-one patients with lumbar degenerative disease accompanied with osteoporosis from Jun 2008 to Jan 2013 were selected, including 11 males and 20 females with an average age of 73.5 years (range, 65-86 years). There were 14 cases of lumbar degenerative stenosis, 9 of lumbar intervertebral disc herniation combined with segmental instability, 6 of lumbar degenerative spondylolisthesis, and 2 of lumbar degenerative scoliosis. The patients were treated with lumbar canal decompression, fusion and polymethylmethacrylate augmentation of a cannulated and fenestrated pedicle screw fixation according to their clinical features and imaging data. Visual analog scale for pain evaluation was used before and after fixation, the Japanese Orthopaedic Association (JOA) scale was used for assessment of neurological function and life skils before internal fixation and during folow-up. RESULTS AND CONCLUSION:Al cases were folowed up for 40 months (range, 36-48months). No screw breakage, rod breakage, screw extraction, loosening, pseudoarticulation formation, or incision infection was found. The postoperative visual analog scale score and the JOA score was remarkably improved (P < 0.05). For patients suffering from lumbar degenerative disease accompanied with osteoporosis, polymethylmethacrylate augmentation of a cannulated and fenestrated pedicle screw fixation is helpful for increasing the stabilization of screw and preventing from loosening and dislocation of the screws, and thereby beneficial for improvement and maintenance of clinical efficacy.

Objective To investigate the prognostic value of interim and post-therapy 18F-FDG PET-CT in patients with peripheral T-cell lymphoma.Methods A retrospective analysis was conducted on data from 44 patients with newly diagnosed peripheral T-cell lymphoma who underwent interim (after 3 cycles of chemotherapy,27 cases) or posttherapy PET-CT (after the completion of first-line therapy,35 cases).Interim and posttherapy PET-CT status (positive vs negative) was visually interpreted according to criteria of the International Harmonization Project,and PET-CT status was assessed for its ability to predict progression-free survival (PFS) and overall survival (OS).Results Interim 18F-FDG PET-CT results were positive in 16 cases and negative in 11 cases.The median PFS and OS in the patients with positive results were 8 months and 14 months,respectively,while those in patients with negative results were 30 months and 39 months,respectively.The 2-year PFS and 3-year OS rates in patients with positive results at interim PET-CT were 18.8 ％ (3/16) and 12.5 ％ (2/16),respectively,while those in patients with negative results were 90.0 ％ (10/11) and 63.6 ％ (7/11),respectively (x2 =13.092,P =0.000; x2 =7.386,P =0.007,respectively).Posttherapy 18F-FDG PET-CT results were positive in 14 cases and negative in 21 cases.The median PFS and OS in patients with positive results were 10 months and 22 months,respectively,while those in patients with negative results were 26 months and 38 months,respectively.The 2-year PFS and 3-year OS rates in patients with positive results at posttherapy PET-CT were 7.1％ (1/14) and 14.3 ％ (2/14),respectively,while those in patients with negative results were 76.2 ％ (16/21) and 57.1％ (12/21),respectively (x2 =15.574,P =0.000;x2 =6.245,P =0.012,respectively).Conclusion Both interim PET-CT status and posttherapy PET-CT status have significant value in monitoring response to therapy and predicting prognosis for patients with peripheral T-cell lymphoma.

Objective To study the clinical value and the safety of endoscopic retrograde cholangio-pancreatography(ERCP)for chronic pancreatitis in the pediatric population.Methods Clinical data,endo-scopic reports,and radiography of chronic pancreatic patients aged from 2 to 17 years old who underwent ERCP between Jan.1,2008 and Apr.30,2014 at Endoscopy Center of Ruijin Hospital were reviewed.These patients were divided into 3 groups,patients aged from 2 to 6 years old as children group(n =27),patients aged from 7 to 12 years old as juvenile group(n =35)and patients aged from 13 to 17 as adolescent group(n =25). Their clinical data and complications were analyzed by groups.Results A total of 170 ERCP procedures were performed in 87 patients,with the success rate of 99.4%(169 /170).All patients were diagnosed as having chronic pancreatitis by ERCP.Success rates of children group,juvenile group and adolescent group were 97.6%(40 /41),100.0%(72 /72)and 100.0%(57 /57)respectively.There was no statistically significance among the three groups(P =0.207).No serious complications like bleeding or perforation occurred.No proce-dure-related mortality occurred in this study either.The rate of post-ERCP adverse events in children group, juvenile group and adolescent group were 41.5%(17 /41),25.0%(18 /72)and 24.6%(14/57),respective-ly.Children group had more adverse events than the juvenile group(P =0.039)and adolescent group(P =0.045).Conclusion Pediatric ERCP is highly effective in the pediatric population with chronic pancreatitis. The incidence of post ERCP adverse events is higher among the youngest children.

Vascular stent is an important medical appliance for angiocardiopathy. Its key deformation process is the expandable progress of stent in the vessel. The important deformation behaviour corresponds to two mechanics targets: deformation and stress. This paper is devoted to the research and development of vascular stent with proprietary intellectual property rights. The design of NiTinol self-expandable stent is optimized by means of finite element software. ANSYS is used to build the finite element simulation model of vascular stent; the molding material is NiTinol shape memory alloy. To cope with the factors that affect the structure of stent, the shape of grid and so on, the self-expanding process of Nitinol stent is simulated through computer. By making a comparison between two kinds of stents with similar grid structure, we present a new concept of "Optimized Grid" of stent.

OBJECTIVETo clone luffin-a cDNA from the seeds of Luffa cylindrical, and to obtain bioactive recombinant luffin-a protein using the expression vector pET-44a (+) in E. coli.

METHODSThe cDNA sequence encoding luffin-a was cloned from the fresh seeds of Luffa cylindrical by RT-PCR. The target DNA fragments were sequenced after T-A cloning. The luffin-a expression plasmid was constructed by inserting the luffin-a cDNA fragment into vector pET-44a (+). Luffin-a was expressed in E. coli by addition of IPTG into final concentration 1.0 mmol/L. The recombinant luffin-a was identified by SDS-PAGE. The biological activity of luffin-a protein was evaluated by using the MTT assay in HepG2 cells following fluid-phase endocytosis.

RESULTSIn comparison with the reported luffin-a, the homology of nucleotide sequence of the cloned luffin-a gene was 99.73%, while their amino acid sequences were identical. The solubility of recombinant protein was analyzed by SDS-PAGE, and the luffin-a was mainly produced in inclusion bodies. The recombinant luffin-a, renatured by dialysis of the denatured products, showed a similar cytotoxicity to ricin A chain.

CONCLUSIONThe cDNA of luffin-a has been successfully cloned. The recombinant luffin-a protein expressed by E. coli is bioactive.

OBJECTIVETo compare the therapeutic effects of aspiration via a directional soft tube and conservative treatment in patients with mild hemorrhage in the basal ganglion.

METHODSSeventy-five patients with mild cerebral hemorrhage (10~30 ml) were randomly divided into two groups for aspiration treatment with minimally invasive directional soft tube placement (minimally invasive group, n=36) and conservative treatment (medication group, n=39). The patients in the two groups had comparable mean GCS scores of 11-15 on admission. The clinical outcomes of the patients were compared between the two groups.

RESULTSIn the minimally invasive group, complete removal or absorption of the hematoma occurred within an average of 3.8 days, significantly shortened in comparison with the 24 days in the medication group. The short-term (1 month) follow-up of the patients showed good neurological recovery in 58% of the patients in the minimally invasive group, significantly greater than the rate of 29% in the medication group; 6 months after the treatment, good neurological recovery was achieved in 50% of the patients in the minimally invasive group, but only 16% in the medication. No death occurred in the minimally invasive group, and 2 patients died in the medication group. The cost of hospitalization averaged 5136.3 Yuan in the minimally invasive group and 11843.6 Yuan in the medication group.

CONCLUSIONCompared with conservative treatment, the minimally invasive treatment with soft tube placement can significantly shorten the hospital stay, promote neurological function recovery, lower the mortality rate, and reduce the cost of hospitalization.

OBJECTIVETo explore the combined anti-tumor effect of radiation therapy and gene-targeted suppression of tumor neovasculature in lung adenocarcinoma in vivo, and to explore the feasibility of micro-PET/CT in dynamic evaluation of treatment effectiveness.

METHODSThirty 5-6-week old male BALB/c nude mice were used in this study. The mouse models of xenotransplanted human lung adenocarcinoma were divided into 5 groups at random, six mice in each group: the control group, radiation treatment alone group and three groups of recombinant baculovirus plus radiation treatment (intratumoral injection, tail vein injection, and intramuscular injection). The tumor volume was measured every 2 days. Growth delay time (GD) and growth inhibition rate was calculated. FDG metabolism was evaluated by micro-PET-CT before and after treatment. The expressions of VEGF, CD31 and Ki-67 were detected by immunohistochemistry (IHC).

RESULTSThe tumor growth delay was >12 days, and the tumor inhibition rate was >45% in the recombinant baculovirus combined with radiotherapy groups, significantly higher than that of the radiotherapy alone group (P < 0.05). Immunohistochemical analysis showed that the expressions of VEGF, CD31 and Ki-67 were significantly lower than that in other groups (P < 0.05). The micro-PET-CT assessment showed that the FDG-metabolism in the recombinant baculovirus combined with radiotherapy groups was significantly reduced (P < 0.05), and the SUVmax (FDG metabolism) of transplanted tumors after treatment was also markedly decreased in comparison with that of the control group. The tumor volume after treatment was significantly correlated with SUVmax in the recombinant baculovirus intratumoral injection + radiotherapy group(r = 0.976), recombinant baculovirus intravenous injection + radiotherapy group (r = 0.954), recombinant baculovirus intramuscular injection + radiotherapy group (r = 0.929), and radiotherapy alone group (r = 0.871, P < 0.05).

CONCLUSIONSThe recombinant baculovirus containing Egr1 promoter and K5 gene combined with radiotherapy enhances the suppressing effect on the growth of lung adenocarcinoma in the tumor-bearing nude mice. The inducibility of Egr1 promoter by radiation allows the targeting and controllability of treatment. Micro-PET-CT results have a good correlation with the treatment effectiveness. Therefore, it can be used in real-time evaluation of tumor metabolic function in vivo.

OBJECTIVE: To explore the effect of ulinastain on the expression of hemeoxy genase-1 (HO-1) in oil acid-induced acute lung injury in rats. METHODS: The animal model of acute lung injury was established by oil acid. Thirty SD rats were randomly divided into 3 groups: the blank control group (A), the acute lung injury group (B) and the acute lung injury group (C) followed by injecting 100 mL/kg ulinastatin. Each group consisted of 10 rats. Group A were given 0.2 mL/kg natural solution through the trial vein; Group B and C were given 0.2 mL/kg oil-acid through trial vein, while group C were injected 100mL/kg ulinastatin by the peritoneal cavity after injecting oil acid. After 4 hours, the rates of respiration were counted and blood samples were cramped out through the heart puncture for blood gas analysis. The expressions of hemeoxygenase-1 and the pathologic construction changes were determined by HE staining in the lower right lung of rats in the 3 groups. RESULTS: The respiration dysfunction caused by oil acid could be prominently improved by ulinastain. There was only a little expression of hemeoxygenase-1 in the lung of Group A, but the expression increased in Group B and significatively increased in Group C. CONCLUSION Ulinastatin may protect the rats from acute lung injury through increasing the expression of HO-1.
