OBJECTIVE To investigate the expression profile of inflammation related genes in laryngeal squamous cell carcinoma by functional gene chip technique and to probe into the role of correlative genes in pathogenesis of the laryngeal squamous cell cancer and in tumor immunity. METHODS The total RNAs were respectively extracted from two pair samples of laryngeal tumor and the normal tissue around the tumor, and then were reversely transcribed to cDNAs, then synthesized to cRNAs. The cRNAs were labeled with the hybridization probes. The probes were then hybridized with four pieces of inflammation related genes chip. It was chemiluminescently detected and the acquired image was analyzed with special software. RESULTS Forty genes were differently expressed in inflammation related gene profile of laryngeal tumor, among which 22 genes were upregulated and 18 genes were down regulated. Thirteen genes were shown differential expression in both chips with 10 upregulated genes and 3 downregulated genes. CONCLUSION The differently expressed genes in inflammation related gene chips will provide clues and theoretical foundation for the investigation of the relationship between tumor and inflammation, and also the immune pathogenesis of laryngeal tumor. Furthermore CCL-7 may have an important role in the occurrence of laryngeal cancer, and the role of immunity of the pathogenesis of laryngeal tumor needs further studied.

Objective To investigate the separate and combined detection value of serum carbohydrate antigen 125 (CA125),human epididymis protein 4 (HE-4) and D dimer (D-dimer) in the diagnosis of ovarian cancer.Methods One hundred and twenty ovarian cancer patients were selected as the observation group,one hundred and twenty patients with ovarian benign tumor as the benign group,eighty women with healthy physical examination results as the control group,then the chemiluminescence immunoassay was used to detect the expression of serum CA125 and HE-4 of the three groups,and the immune turbidimetric method was applied to examine the expression of D-dimer.At last,the diagnosis efficiency of CA125,HE-4 and D-dimer in separate and combined detection was calculated.Results CA125 in the observation group was (623.07±274.18) U/ml,HE-4 was (594.22±329.068) ng/ml and D-dimer was (418.57±276.75) ng/L,CA125 in the benign group was (45.09±32.58) U/ml,HE-4 was (97.92±57.52) ng/ml and D-dimer was (204.52±80.07) ng/L;CA125 in the control group was (40.23±28.16) U/ ml,HE-4 was (85.65±37.27) ng/ml and D-dimer was (187.57±65.74) ng/L,the differences between the three groups were statistically significant (F=122.82,89.91,54.46;P<0.05).The level of CA125 in the serum of patients with advanced stage (stage III-IV) was (586.10±278.33) U/ml,HE-4 was (437.49±238.06) ng/ml,D-dimer was (493.78±274.45) ng/L,in the early stage (stage I-II),the level of CA125 in the serum of patients with ovarian cancer was (372.12±265.31) U/ml,HE-4 was (673.64±301.68) ng/ml,D-dimer was (364.84±267.54) ng/L,and the difference was statistically significant (t=4.244,4.78,2.560,P<0.05).The detection sensitivity and specificity of CA-125 were 71.67% and 62.50% respectively.The sensitivity of HE-4 was 74.17% and the specificity was 75.00%.The sensitivity of D-dimer was 62.5% and the specificity was 60.00%.The combined detection sensitivity of the three was 80.00% and the specificity was 77.5%.Conclusion The sensitivity and specificity of the three tumor markers in combined detection were higher than those of separate detections,so the combined detection of CA125,HE-4 and D-dimer can further improve the diagnosis level of ovarian cancer.

Objective To investigate the effect on electrical restitution of β1-adrenergic receptor antagonist esmolol administered during cardiopulmonary resuscitation in the porcine ventricular fibrillation model. Method Ventricular fibrillation untreated for four minutes was induced by dynamic steady state pacing protocol in 40 healthy male pigs, in which local unipolar electrograms were recorded using one 10-electrode catheter that was sutured to the left ventrieular epicarditan. During CPR, animals were randomized into two groups to receive saline as placebo or esmolol after two standards doses of epinephrine. At postresuscitation 2-hour, six pigs were randomly selected from each group and the second VF induction was performed. Local activation-recovery intervals (ARI) restitutions and the VF inducibility between control group and esmolol group were compared. Western blotting was performed to determine cardiac ryanodine receptor (RyR2) protein expression, and their phosphorylation status. Results No sig-nificant differences were observed at the restoration of spontaneous circulation between two groups. Higher postre-suseitation 2-hour survival rate was observed in the esmolol group. Esmolol significantly flattened ARI restitution slope, lessened regional difference of ARI restitution, decreased the VF inducibility, and alleviated RyR2 hyper-phosphorylation. Conclusions Esmolol given during CPR significantly improved postresuscitation 2-hour survival rate. Its effects on modulating electrical restitution property and intracellular calcium handling make up the most important reasons why β1-blockade significantly reduced the onset and maintenance of VF.

Objective To investigate effects and safety of dexmedetomidine on the prevention of abnormal mental in patients after liver transplantation.Methods 160 patients after liver transplantation were randomly divided into the two groups using the drawing method:midazolam group(n =80),dexmedetomidine group(n =80),compared the two groups of patients with general,mental abnormality and the occurrence of adverse reactions.Results There were no significant differences in the general situation (gender,age,postoperative ventilator time,ICU stay time,oper-ation time,blood FK506 concentration,APACHEII score 24 hours after operation)of the two groups of patients (P >0.05),the spirit of the abnormal rate of the observation group was lower than that of the control group (P =0.009), incidence of hypotension and hypertension in the observation group was higher than that in the control group (P =0.035,0.029).Conclusion Dexmedetomidine can effectively reduce the postoperative mental disorders in patients in the early stage after liver transplantation.

ObsjectiveTo investigate the clinical data,and to summarize the clinical experience of diagnosis and treatment of graft-versus-host-disease (GVHD) after liver transplantation.Methods 4 of 480 recipients undergone liver transplantation developed GVHD from Apr.2005 to Sep.2011.The 4 recipients'clinical courses and laboratory tests were recorded.ResultsThe diagnosis of GVHD depended on clinical syndrome involved skin rash,bone marrow depression and diarrhea.Skin biopsy and STR-PCR were matched.Among them,2 with successful treatment have been surviving for 7 and 24 months,and 2 died from infection.One recipient had the donor T lymphocyte microchimerism detected by STR-PCR.ConclusionsGVHD after liver transplantation can cause high mortality due to bone marrow depression.A reasonable treatment can be to reduce immunosuppressant and glucocorticoids and IVIG.

Objective To study the rehabilitation effects of the cochlear implants on prelingually deaf children with alba abnormality.Methods A retrospective analysis of the effects of CIs was conducted in the prelingually deaf children of 11 cases of the children with abnormal alba(the research group) and 18 cases of the children who had normal alba(the control group) at the First Affiliated Hospital of Fujian medical university.All the operations were completed by the same doctor.There were no obvious complications during and after the operation.The cochlear implants were turned on after one month and the prelingually deaf children with extremely severe bilateral sensorineural deafness were trained for speech at the rehabilitation centre.The assessment criteria of the categories of auditory performance(CAP) and speech intelligibility rate(SIR) were used.After six months and twelve months of the operation, the family members were followed who have direct contacts with the children.The evaluation of data between the research and the control groups was administered.Results In the research group, the average level of CAP after six months'' post-operation was 2.41±0.47.But in the control group, the average level was 3.28±0.45.In the research group, the average level of SIR after six months'' post-operation was 1.27±0.44.There were 3 children in the research group at level 2, but in the control group, the average level was 1.89±0.31.Two children in the control group were level 1 while the others were level 2.In the research group, the average level of CAP after twelve months'' post-operation was 4.00±0.43 while only one child at level 3.There was one child at level 5 in the research group, the rest were level 4.There was a statistically significant difference in the average level of the CAP after six months'' post-operation(t=4.983, P<0.05) and in the average level of the SIR after six months'' post-operation(t=4.371, P<0.05).There was no statistical difference in the average level of the CAP after twelve months'' post-operation(t=1.033, P>0.05) and in the average level of the SIR after twelve months'' post-operation(t=0.434, P>0.05).Conclusion There is no significant difference of the rehabilitation effects of post-operation between the prelingually deaf children with alba abnormality and those with normal alba.

OBJECTIVE: To investigate whether the allergic factors impact the severity of chronic rhinosinusitis or not, further more, to explore the relationship between allergic rhinitis and chronic rhinosinusitis. METHOD: A retrospective review was done on 103 patients. All of these patients were under functional intranasal endoscopic sinus surgery after expectant treatment is ineffective. We devided the patients into different groups according to the result of skin prick and specific IgE and if there is difference in VAS score, Lund and Kennedy endoscopic score, Lund-Mackay CT score between the groups. We also analysed the symptoms in different chronic rhinosinusitis patients allerged to variant kinds of allergen. The SPSS 17.0 software was used to analyze the data. Statistical analysis was performed by t-test, rank order test or χ2 test. RESULT: The duration of the disease, VAS score of nasal blockage, score of Lund-Mackay CT and Lund and Kennedy endoscopic before the operation were in no statistical sense after when compared with the two groups of patients with chronic rhiriosinusitis who grouped according the result of skin prick and specific IgE. The VAS score of facial pressure and loss of smell was higher in patients with chronic rhinosinusitis which the skin prick and specific IgE were positive. The VAS score of nasal discharge was higher in patients with chronic rhinosinusitis who got negative skin prick and specific IgE result. The symptoms of chronic rhinosinusitis improved with operation no matter the group of skin prick and specific IgE positive or negative and VAS score of nasal blockage improved significantly in negative group. The symptoms of sneezing, rhinorrhoea and rhinocnesmus improved after operation among the chronic rhinosinusitis patients with skin prick and specific IgE. The number of cockroach allergy is larger among the patients with chronic rhinosinusitis without polyps than the one among the patients with chronic rhinosinusitis with polyps. CONCLUSION Allergic factor didn't impact much the severity of chronic rhinosinusitis patients who were failed in expectant treatment, besidesthe postoperative outcomes showed that only influence the severity of nasal discharge, facial pressure and loss of smell. Different kinds of allergen were found between the patients of chronic rhinosinusitis with or without polyps. No significantly functional endoscopic sinusitis sugrery outcome were related to the allergic factor. But the allergic factor may interfere the remission of nasal discharge after surgery.

Objective To identify the level of functional immunity as measured by the ImmuKnow assay in Chinese stable liver transplant recipients and to correlate these values with the dose and the trough levels of immunosuppressant, and with other clinical parameters of these patients. Methods Functional immune response was assessed by the ImmuKnow assay in 46 blood samples taken from 46 stable liver transplant recipients from Beijing Youan Hospital, Capital Medical University Liver Transplantation Center. Results The average ATP value in these stable liver transplant recipients was 203±114 ng/ml (range: 38.47 ATP ng/ml to 524.06 ATP ng/ml) at 22± 15 month post liver transplantation. There was no correlation either between ImmuKnow ATP values and the tacrolimus trough levels, or between ImmuKnow ATP values and the liver function (P<0. 05). Stepwise multiple regression analysis identified WBC and CD3+, CD3+ CD4+ as independent predictors of ImmuKnow assay levels when age, gender and underlying diagnosis were taken into account (P<0. 05). Five patients who were detected to have active HCV infection had lower ImmuKnow ATP values (<61 ng/ml). Conclusions The Cylex ImmuKnow assay ATP values were lower in Chinese stable liver transplant recipients compared with American patients. Further investigation is required to determine the role of the ImmuKnow assay in tailoring immunosuppressant therapy in liver transplant recipients.
