At present, the surgical treatment of peripheral facial paralysis includes non-dynamic and dynamic treatment. The former suspends the facial soft tissue with various materials to reconstruct the static symmetry of the face. The latter, through nerve repair and the transplantation of vascularized neuromuscular flap, restores the facial nerve and expressive muscle contractile function of the affected side, to achieve the ideal therapeutic effect. This article summarises the relevant literatures, reviews the application of various nerve repair methods in peripheral facial paralysis, to discusses the scope of application, advantages and disadvantages, and provides reference and help for clinicians in selection of surgical methods for peripheral facial paralysis.

Aim To isolate the female-specific sequence of Schistosomajaponicum S. J. in order to provide a basis for researching vaccines of anti-fecundity. Methods Representational difference analysis (RDA) was used to obtain a female-specific sequence of S.j. by the male S.j. genomic DNA substractive hybridization with the female. The fragment was about 562bp. Results This sequence was labeled as Dig probe by PCR technique to hybridize with the restriction fragments of each sex and the tester as well as the driver on the nylon membranes.The antiboly of Dig、 NBT、 and X-phosphate solution were utilized to immunoassay the result of hybridization. The result showed that the probe can hybridize to the tester but can not hybridize to the driver. Conclusion The result suggested that the fragment of approx. 562bp was the female-specific sequence of Schistosoma japonicum.

Objective To introduce a method and the clinical effects of treating the blocks of nasal-lachrymal ducts by the memory alloy stands without TV monitoring.Methods 15 blocks of nasal-lachrymal ducts of 12 cases were taken radiography of nasal-lachrymal ducts;to fix the position,to put into the conducting threads from the tear spots and introduce the dilators inversely along the threads.And then China-made titanium-nickel memory alloy stands were planted into the nasallachrymal ducts.Results To visit the patients for 1 to 12 months after operation,the radiography showed that the nasal-lachrymal ducts were clear.The symptoms of overflowing tears and pus disappear completely,11 blocks of 9 cases fully recovered,4 blocks of 3 cases were on the mend.Conclusion Interventional treatment of blocks of nasal-lachrymal ducts is easy,safe and effective.

Objective To investigate the correlation between the expression of vascular endothelial growth factor-C(VEGF-C) and lymph node metastasis in gastric cancer. Methods The expression of VEGF-C was detected in 30 pairs of fresh primary gastric cancers and their adjacent normal tissues from the same patients by semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemistry. Automated image analyzer was used to quantify VEGF-C expression, which was reflected by positive index (PI). Results VEGF-C was highly expressed in gastric cancer cells,whilst its expression was undetectable in adjacent normal tissues. VEGF-C expression was higher in lymph node metastasis group(PI=1.345?0.079) and lymphatic invasive(PI=1.315?0.037) group than that in no-metastasis group(PI=1.156?0.045) and no-invasive group (PI=1.154?0.043)(P

Radiation enteritis significantly affects the quality of life in the patients receiving radiotherapy due to pelvic tumor.As an intestinal inflammation related to radiotherapy, radiation enteritis is an inflammation of the mucous membrane in nature based on some basic research.Studies demonstrate that programmed necroptosis might play a role in the development of inflammatory bowel disease;therefore, as a subtype of inflammatory bowel disease, programmed necroptosis also might play a role in the development and progression of radiation enteritis.This paper aims to review the studies about the nature and pathogenic mechanism in order to contribute to the treatment of radiation enteritis and improve patients'' quality of life.

OBJECTIVETo investigate the application and therapeutic effect of frontal muscle fascia compound flap suspension for congenital blepharoptosis in children.

METHODSFrom July 2010 to March 2012, 21 children (23 eyes) with congenital blepharoptosis were treated with frontal muscle fascia compound flap suspension. The therapeutic effect was observed and followed up.

RESULTS17 patients were followed up for 3-6 months with relapse in one case. The ptosis was corrected in the other 1 cases.

CONCLUSIONThe frontal muscle fascia compound flap suspension is effective and practical with minimal morbidity and lower complication for the correction of congenital blepharoptosis.

Background Magnetic activated cell sorting(MACS)is a new immunomagnetic separation technique.It's principle is based on the specialized recognition between the antibody and antigen.When directed or indirected coupled with the 50 nm magnetic beads,the antibody can linked with the cells which express the corresponding antigen,and then leads to the magnetic cell separation in a high intensity and high-gradient magnetic field.The method has higher separative purity and recovery and been made use of enriching tumor cells and tumor stem cells.It could be also utilized to enrich the rare tumor cells in fluid specimen.Objective To evaluate the enriching efficiency of detecting free cancer cells in analogue malignant ascites using MACS and a panel of tumor-specific markers.Methods Five species of tumor cell lines correlated to the diseases resulting in malignant ascites were selected and the expressions of EpCAM,CAl25,CEA,TAG-72 and their mixture in these tumor cell lines were detected using immunofluorescence reactions and flow cytometry(FCM).The tumor cells were spiked into mononuclear cells by different ratios to analogue the main ingredients of malignant ascites.The efficiency of MACS combinded with mixture antibodies in separating tumor cells was compared with single antibody.Results The FCM revealed that the expression of the mixture antibodies in 5 tumor cancer cell lines was significantly higher than that in single antibody.The mean recovery rates of spiked tumor cells were enhanced by using a panel of monoclonal antibodies combined with MACS than single antibody,especially in two gastric cancer cells and colon cancer cells(69.18%±20.84%VS 45.23%±11.54%,78.75%±15.42%vs 59.73%±16.64%and 85.63%±12.30%VS 76.88%±8.65%,respectively),the ovarian cancer cells was the next(32.49%±3.58%vs31.79%±4.82%),and the liver cancer cells was the lowest(11.78%±0.43%VS 7.16%±0.46%).Conclusions The detection of free cancer cells from malignant ascites by MACS combined with a panel of monoelonal antibodies is more effectively than single antibody.The method has the potencial value of clinical application to the malignant ascites caused by gastroenteric tumor.

Objective To explore whether miR-451 suppresses cell migration and invasion by targeting macrophage migration inhibitory factors (MIF),thus to reveal molecular mechanism that miR-451 functions as a tumor suppressor in gastric cancer.Methods A quantitative real-time polymerase chain reaction (qRT-PCR) was carried out to detect the expression of miR-451 in gastric cancer and normal stomach mucosa.Western blotting was performed to detect the expressions of MIF protein regulated by miR-451 in MGC 803 cells.The migration and invasion abilities of MGC-803 cell were evaluated with wound-healing and transwell invasion assays.Results miR-451 was down-regulated in gastric cancer tissues.The expressions of miR-451 were negatively correlated with the clinical stage and lymph node metastasis in gastric cancer patients.Western blot showed that a notable reduction of the protein level of MIF by restoring miR-451 in MGC-803 cells.Overexpression of miR-451 inhibited the migration and invasion of MGC-803 cells.Conclusions miR-451 suppresses cell migration and invasion by targeting MIF in gastric cancer.

Objectiye To reveal epidemiology of malignant tumor in Quanzhou area of Fujian province. Methods Medical record of adults who received health check-up between 2006 and 2010 was collected to estimate the incidence of malignant tumor. Chi-square test was used for data analyses.Results Nearly 12 323 individuals received an annual health check-up during 2006 and 2010,177 of whom were found to have malignant tumors. The identification rate of malignant tumors was 2. 87‰ per year, and the most commonly seen cancer included liver cancer ( 42. 93% ), lung cancer ( 20. 90% ), oesophageal cancer (9. 03% ), cervical cancer ( 8.47% ) and gastric cancer (6. 78% ). Those of 60 to 70 years old showed the highest incidence of cancer. Conclusion Annual health check-up may be helpful to identify early-stage malignant tumors.
