Objective To observe whether endomorphin-2-immunoreactive(EM2-ir) neurons in the trigeminal ganglion(TG) project to the medullary dorsal horn(MDH) in the rat. Methods Fluoro-gold(FG) retrograde tracing and immunofluorescent histochemical staining for EM2 were applied. Results After FG was injected into the MDH,many FG labeled neurons with small,medium and large diameters were observed in the TG.There were also aboundant EM2-ir neurons with different diameters in the TG.The majority of FG labeled neurons in the TG showed EM2-immunoreactivities.Almost all of the EM2/FG double-labeled neurons were medium and small in size.Conclusion EM2-ir neurons in the TG project to the MDH in the rat.

BACKGROUND: Threatened abortion is a high risk pathological change during gestation. Fetus usually could be protected after the application of all kinds of medical interventions; however, whether the healthy development of the newborn could be assured simultaneously when a new life is protected?Especially the long-term impact on the normal development of the intelligence is an important issue deserving investigation.OBJECTIVE: To investigate the differences of intelligence level between protected fetus after threatened abortion and normal mature fetus, and the influencing factors.DESIGN: A case-controlled observational comparative study introducing children as the subjects.SETTINGS: Psychological department of a normal university; Department of gynecology and pediatrics of a district women and children' s health care hospital.PARTICIPANTS: Totally 170 children(mature and natural delivery after protection) of 5 to 7 years old, whose mothers experienced threatened abortions during gestation, and 182 children born in the same period(normal mature and natural delivery) of 5 to 7 years old, whose mothers did not have threatened abortion history were selected as the subjects. No other factors would affect the intellectual development in the subjects of both groups.INTERVENTIONS: The Chinese Version of Wechsler young children scale of intelligence(C-WYCSI) for children below 6 years old or Wechsler intelligence scale for children-Chinese revision( WISC-CR ) for children no younger than 6 years old were introduced in the individual test performed by trained psychological junior students for every testee.children in both groups [intelligence quotient(IQ) gained in the intelligence of mother on the intellectual development of the children in both groups.was found in the testees, the IQ of all tested children was within the normal dren was sinificantly lower in the threatened abortion group than in the normal were significant interactions between threatened abortion and gender, body mass at birth and the pregnant age of mother, etc.: if the mother experienced threatened abortion, the newborn would be even more easily to suffer from relative low body mass at birth(low body mass fetus accounted for 28% of threatened abortion group, which accounted for about 66% of the total low body mass at birth fetuses in our study); the male newborn would be even more easily to have relative low intellectual development(the difference of IQ between the male children of two groups was significant) (F = 2. 809, P < 0.05). Especially, the negative impact on children' s intellectual development would be even greater if the pregnant woman were older than 35 years old and had threatened abortion experience(the average IQ of 32 tested children was 86).CONCLUSION: Threatened abortion might be a potential innate factor that would affect the intellectual development of the children. For those high-risk individual cases with this kind of experience, early intervention should be prepared as early as possible to create a favorable substantial and culture environment for avoiding the actual occurrence of delayed intelligence.

Objective To investigate effect of coagulation, fibrinolysis, platelet and tumor markers in patients with advanced lung cancer by chemotherapy.Methods 21 cases of advanced lung cancer patients were selected to be the experiment group, and 20 healthy people were selected to be the control group.The experiment group were treated by chemotherapy,coagulation, fibrinolysis, platelet and tumor markers were compared before and after the treatment.ResuIts Compared with experiment group before chemotherapy, PT, APTT, TT levels of the patients after chemotherapy were lower, serum FIB concentrations were higher (P<0.05); PC and FPS were lower , D-D, PAI-1 concentration level were higher (P<0.05); PLT, MPV, PDW levels were lower (P<0.05); CEA, CYFRA21-1, NSE, CA125 levels were lower (P<0.05).ConcIusion Chemotherapy can enhance the effect of coagulation system in patients with advanced lung cancer, inhibit the fibrinolytic system and reduce the level of tumor markers.

Objective To identify new serum biomarkers of lung adenocarcinoma.Methods Serum samples from 31 patients with lung adenocarcinoma and 31 healthy individuals were applied to SAX-2 protein chips to generate proteomic spectra by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry(SELDI-TOF-MS).The spectra were analyzed with Ciphergen Biosystems software and biomarker patterns software.Results The software identified 102 peaks and m/z 14 022.9 and 3 735.99 were used to construct the classification tree.The classification tree separated adenocarcinoma of lung effectively from healthy individuals,achieving a validity of 100%.The blind test challenged the model with a sensitivity of 100%and a specificity of 100%.Conclusions The results suggest that SELDI-TOF-MS technique can distinguish lung adenocarcinoma patients from healthy individuals and shows great potential for the development of a screening test for the detection of lung cancer.

Objective To discuss the features and surgical management of ectopic hyperparathyroidism.Methods Clinical data of 66 cases of ectopic hyperparathyroidism were retrospectively analyzed.Results There were 66 cases of ectopic hyperparathyroidism accounting for 11.5％ (66/575) of all ectopic hyperparathyroid cases admitted during the period from 1982-2010.Prevalence of mediastinal ectopic lesions was 71.2％ (47/66),among those 65.2％ (42/66) was in anterosuperior mediastinum,and 28.8％ (19/66) in the non-typical loci of the neck.Radionuclide imaging of parathyroid glands was the most sensitive (87.0％) method among all common positioning examinations.Average number of operation episode was 1.47,and all lesions were finally resected.After surgery 49 cases presented with transient hypocalcemia,and were cured by calcium administration.52 cases were followed up,with recurrent hyperparathyroidism in 1 case.Conclusions Diagnosis and treatment of ectopic hyperparathyroidism are dependent on the understanding of common locations of ectopic parathyroid glands.Preoperative correct location and surgical expertise are helpful for successful resection.

Objective To study the impact of different low concentrations of cerium oxide for hepatocellular carcinoma cell prolifera-tion.Methods Three different types of hepatoma cells (Huh7, HepG2,7721) were cultured,and added different concentrations of cerium oxide (0.005,0.01,0.05,0.1,1 μg/mL),of which the cell proliferation was detected by CCK8.The apoptosis-related genes was detected by qRT-PCR technology.The cell cycle was analyzed by flow cytometry.And the effect of low concentration cerium oxide on hepatocellular carci-noma cells tumorigenicity was confirmed by the nude mice experiments.Results CCK8 experiment showed that low concentrations of cerium oxide could promote proliferation of hepatocellular carcinoma cell, especially in concentration of 0.01μg/mL.The qRT-PCR showed that low concentration of cerium oxide could inhibit the apoptosis of hepatocellular carcinoma cell.The flow cytometry analysis had not found any effect of cerium oxide on cell cycle.The tumorigenicity experiments confirmed that low concentrations of cerium oxide could enhance the tumorigenic ability of hepatocellular carcinoma cell.Conclusion Low concentration of cerium oxide can significantly improve the proliferation of liver cancer cells.

BACKGROUND:Transoral ventral release and posterior fusion have predominated in the treatment of irreducible atlantoaxial dislocation, but there is no consistent conclusion on the clinical efficacy.
OBJECTIVE:To explore the clinical outcomes of transoral ventral release and posterior fusion and screw/rod implantation in the treatment of irreducible atlantoaxial dislocation.
METHODS:A total of 32 patients with irreducible atlantoaxial dislocation undergoing thetransoral ventral release and posterior fusion were selected. After treatment, they received cervical anteroposterior and lateral digital DR and cervical MRI examinations to understand the conditions of nerve compression and bone fusion. The recovery of nerve function was evaluated using Japanese Orthopaedic Association before treatment, 6 months after treatment and during final fol ow-up.
RESULTS AND CONCLUSION:Post-treatment, 29 patients were fol owed-up for an average period of 12 months. (1) Al the patients obtained perfect atlantoaxial joint reduction and bone fusion. This achieved reduction and reconstruction of spinal column stability. (2) Spinal compression was obviously lessened after treatment in al patients, and nerve functions were improved to different degrees. Significant differences in Japanese Orthopaedic Association score were detected between 6 months post-treatment, final fol ow-up and pre-treatment (P<0.05). (3) There were no serious intraoperative complications such as spinal cord or vertebral artery injuries. Postoperative complications such as infection or burst were also not found. (4) Imaging evaluation revealed that transoral ventral release and posterior fusion is safe and effective for treatment of irreducible atlantoaxial dislocation.

Objective To investigate the effect of Octreotide on pancreatic head carcinoma patients with obstructive jaundice who underwent endoscopic retrograde cholangiopancreatography (ERCP) with pancreatic stent placement.Methods Niney-nine patients hospitalized in Department of Gastroenterology of Wuhan Central Hospital from Jan 2006 to Dec 2011 were included in this study.All the patients were diagnosed as pancreatic head carcinoma with obstructive jaundice.The patients were randomly divided into the Octreotide treatment group and the control group.Both groups underwent ERCP with pancreatic duct stent placement for malignant biliary obstruction.The patients in Octreotide treatment group were injected with subcutaneous Octreotide at a dose of 0.1 mg twice per day for more than 90 day till death.The changes of serum total bilirubin before and after treatment were compared.The improvement of symptoms of nausea,vomiting,abdominal pain,diarrhea and anorexia was compared.The complication rates and survival were also determined.Results Postoperative recurrence of jaundice was observed in six patients in control group,and the cause may be stent occlusion,and 3 of the 6 patients underwent a second ERCP and stent placement,then jaundice was relieved,the other 3 patients did not receive a second ERCP.The serum bilirubin level in the remaining 45 patients returned to basically normal value (below 2 times of the normal value).The prevalence of nausea,vomiting,abdominal pain,diarrhea and anorexia in the 2 groups was not statistically different before treatment,and after treatment the prevalence of symptoms in the 2 groups was significantly decreased except for diarrhea.The decrease in Octreotide treatment group was more obvious than that in control group,and the difference between the two groups was statistically significant (P ＜ 0.01).In the control group,post-ERCP pancreatitis occurred in three patients,and all were cured after treatment.There was no post-ERCP pancreatitis occurred in the Octreotide treatment group.Minor pain at the injection site was noted in three patients in the Octreotide treatment group.Pain was relieved after changing the injection site.The survival was significantly longer in the Octreotide group than that in control group [(14.4 ± 8.7) months vs (7.3 ± 5.3) months,P ＜ 0.05),and the difference between the two groups was statistically significant (P ＜ 0.05).Conclusions Octreotide can improve the quality of life and increase the survival of patients with pancreatic head carcinoma who undergo ERCP with pancreatic duct stent placement.
