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.

AIM: To study and analyze the clinical efficacy of diclofenac sodium eye drops combined with sodium hyaluronate eye drops in treating dry eyes after ophthalmic surgery.METHODS: Totally 94 eyes from 94 patients with dry eyes were slected, and they were randomly divided into orbervation group and control group.Fouty-seven patients in the control group using conventional treatment combined with sodium hyaluronate eye drops.Other 47 patients in orbervation group were treated with diclofenac sodium eye drops on the basis of control group.We compared symptoms, fluorescein station, tear film break time, Schirmer Ⅰ test between the two groups.RESULTS: Compared with before treatment, patients of both groups with sympotom, fluorescein station score, BUT, and Schirmer Ⅰ test were significantly improved(P<0.05).At the same time, sympotom, fluorescein station score, BUT and Schirmer Ⅰ test of control group were better than observation group(P<0.05).The cure rates of the orbervation group (98%) were more significant than control group (74%)(P<0.05).CONCLUSION: Diclofenac sodium eye drops combined with sodium hyaluronate eye drops have significant efficacy in treatment of dry eyes after ophthalmic surgery, which can effectively relieve clinical symptoms, improve BUT and Schirmer Ⅰ test.

OBJECTIVE To observe the effect of voriconazole on pulmonary fungals infection after renal transplantation.METHODS Nine cases of pulmanory fungals infection after renal transplantation were analyzed to evaluate the therapeutic effect of voriconazole.RESULTS Treated with voriconazole,seven in nine patients were cured,while the other two died.CONCLUSIONS For patients with pulmanory fungals infection after renal transplantation,the application of voriconazole can receive satisfactory effect.

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 evaluate the safety and feasibility of natural orifice transluminal endoscopic surgery(NOTES)with current available techniques and endoscopic accessories.Methods Transgastric and transvaginal endoscopic abdominal cavity exploration were performed in 6 female pigs.A needle-knife and a ERCP scalpel were used to make an anterior gastric wall incision,and a dilating balloon to expand the passage,through which a therapeutic gastroscope was sent into the abdominal cavity to seek the target organ.Partial liver resection was performed in 2 cases.For incision closure,a clip was applied to the incision orifice or it was just given putting-aside therapy.One week later,the abdominal cavity was examined via vagina.Another week later,it was observed via other incision of the stomach.Four weeks after the operation,the pigs were sacrificed.Adhesion,injury to the organs and closure of the incision were evaluated.Results Transgastric procedures were performed 12 times and transvaginal procedures 6 times.Mean operation time via stomach was 33.4±10.9 min.and that via vagina WaS 10.1±2.5 min.All animals recovered and gained weight after the operation.The incision healed up with no obvious complications.Re-exploration showed adhesion of various degrees,no effusion,or injury to the organs were observed.Ketamine plus propofol achieved satisfactory anesthetic effect with no complications.One of the two animals which underwent liver partial resection died of disphragmatic muscle perforation.Hemarrhage occurred twice,both in the procedures via satisfied.One case developed abdominal abscess.Conclusion It Was feasible and safe to perform NOTES via transgastric and transvaginal approach to the abdominal cavity and liver resection.But development of NOTES specific instruments is essential to the procedure.
