Studies have shown that IL-24 is the only cytokine capable of inhibiting tumor growth and neovascularization as well as stimulating immune system. IL-24 exerts its inhibition effects through pathways independent of p53, Rb, p16 and other tumor suppressor genes and has no effect on normal cells. IL-24 has emerged as a hot topic in cancer therapy research.

Resveratrol is a natural polyphenolic compound. It possesses a variety of biological properties including neuroprotective effects, cardiovascular protection, anti-inflammatory and anti-cancer effects. In recent years, the anti-tumor effects of resveratrol have attracted a lot of attention. Its anti-tumor effects may be mediated by inhibiting tumor initiation, inhibiting tumor cell proliferation, promoting tumor cell apoptosis and inhibiting tumor cell invasion.

Objective To present our experience with laparoscopic pyloromyotomy and laparoscopically assisted endorectal pull through for Hirschsprung's disease (HD) in newborns and infants.Methods Twenty newborns or infants with hypertrophic pyloric stenosis and HD,age ranged from 16～120 days and weight from 2.7～8 kg.Under epidural anesthesia and tracheal intubation,carbon dioxide was insufflated into abdominal cavity via a Veress needle,reaching an insufflative pressure of 12～14 mm Hg.One umbilical and two or three subcostal canulas for instrumentation were demanded.The pyloromyotomy was performed in patients with hypertrophic pyrolic stenosis and in patients with HD the affected colon and rectum were mobilized by dissecting the supplying vessels and cutting the peritoneal reflection,and pull-through procedure was carried out.Results The operation time was 25～150 minutes with rare complications.Oral feeding was resumed on the following day postoperation.The patients recovered and discharged from hospital 3～7 days after operation.Conclusions Laparoscopic pyloromyotomy and laparoscopic endorectal pull-through for HD in newborns and infants are safe and feasible.The advantages of this procedure include minimal trauma to abdomen,rapid restoration of stomach and bowel function and quick rehabilitation.

Objective To review the preliminary experience of primary laparoscopic pull-through for Hirschsprung's Disease in children.Methods Since May 2000,25 patients with Hischsprung's disease underwent Laparoscopic Pull-Through. The oldest age was 6 years old and the youngest was 20 days. All patients underwent anesthesia and tracheal intuition, carbon dioxide was insufflated into abdominal cavity via a Veers needle, reaching a insulation pressure of 1.33～1.86 kPa (10～14 mmHg). One umbilical camera port one-instrument port at left abdomen and one instrument port at right abdomen were made.Results The mean operative time was 165-min. Oral feeding was started 3 days postoperatively. The average hospitalization was 9 days (7～10 days).No complication was encountered.Conclusions Primary laparoscopic Pull-Through for Hirschsprung's Disease in children is safe and feasible.

Objective To report clinical features,diagnosis and treatment in a case of adult onset Still's disease (AOSD) accompanied by demyelinating encephalopathy.Methods We reported a case of Stills disease with signs of encephalopathy.We also reviewed and discussed the literature on the neurological manifestations in AOSD.Results The 35-year-old patient had recurrent fever and arthralgias for 3 years,headache for 1 month and transient loss of consciousness.Laboratory tests showed non-specific immunological activity.MRI showed tumor-like lesions at left parietal and occipital lobes surrounded by sleeve-like edema.The lesion had significant occupation effect.Biopsy proved the presence of demyelinating changes.The patient recovered favorably after administration of corticosteroids and immunoglobulin.The lesions had almost disappeared on follow-up MRI 4 months later.Conclusions Demyelinating encephalopathy may develop in patient with AOSD.MRI may show tumor-like damage,which is rarely reported in the literature.Diagnosis depends on history,clinical manifestation and neuroimaging.Biopsy provides important information in making diagnosis.Treatment with corticosteroids and intravenous immunoglobulin was found to achieve good recovery.

Vacuum pyrolysis of phenolic resin laminate substrate in temperature-programmed furnace reactor was studied.The sample and product oils were characterized by elemental analysis, Fourier transform infrared (FT-IR) analysis and gas chromatography-mass spectrometry(GC-MS).Analytical results showed that the up per clear liquid of pyrolysis oils was mainly consisted of water-soluble substances, such as phenol, cresol, xy lenol, sugars, hydantoins, morpholines, pyranones and pyridine derivatives compounds, etc., while the lower sediment was mainly insoluble or hardly water-soluble substances, such as the big substituent phenolics (the number of substituent carbon atoms of which is greater than or equal to 2), aryl phosphate esters, fatty acid esters and nitrile compounds, and so on.Both of the upper clear liquid and lower sediment have a higher content of melamines.

Toll-like receptor (TLR) is an important pattem recognition receptor (PRR) which partici pates in innate immunity and regulates adaptive immunity.TLR can be expressed in immune cells and malig nant tumors recognize conservative molecular structure,mediate response of inflammation,tissue injury and repair,which plays an important role in the process of tumor.Research results about some molecules and signal pathways of TLR demonstrate that it can act anti or pro-tumor dual functions,which has an extensive prospects in prevention and treatment of tumor.

OBJECTIVE: To investigate the mRNA and protein expression of MICA in laryngeal squamous cell carcinoma tissue and the Hep-2 cells. METHOD: Reverse transcriptase-polymerase chain reaction (RT-PCR) and Western-blot were used to detect the expression of MICA mRNA and protein levels in the Hep-2 cells and laryngeal cancer tissues. RESULT: The MICA mRNA showed higher expression in Hep-2 cells by RT-PCR. Compared with the control, the mRNA expression of MICA was significantly enhanced in laryngeal cancer tissues (t = 11.878, P < 0.01). The intensity of MICA expression is not related to the clinical stage of cancer. MICA protein demonstrated higher level expression by Western blot. The intensity of MICA protein expression was decreased with increased clinical stage in laryngeal cancer tissues. CONCLUSION The MICA mRNA showed stronger expression in Hep-2 cells and laryngeal cancer tissues. The intensity of its expression is not related to clinical stage of cancer. The MICA protein expression was strong in Hep-2 cells. The intensity of MICA protein expression was decreased with increased clinical stage in laryngeal cancer tissues. MICA may play an important role in laryngeal carcinoma process.

Objective To evaluate the effect of early aerosol inhalation on sore throat of the patients after double lumen endobronchial intubation. Methods 90 patients scheduled for thoracic surgery were randomly assigned to 3 groups,30 cases in each group: control group (Group C), early aerosol inhalation group (group one) and later aerosol inhalation group (group two). All patients were sent to PACU after extubation.The patients in group C were intraveously injected with 6 mL saline , those in group one were treated with aerosol inhalation of 1mg budesonide, while the patients in group two with budesonide at the same dosage 2 h later. Patients were examined with indirect laryngoscopy 6 h after surgery. The cases of vocal cord congestion and glottis edema were recorded. The degree of pharyngolaryneal pain was assessed with the Visual Analogue Scale (VAS) when they were sent to PACU , 6 , 24 and 48 hours after surgery . Results The rates of vocal cord congestion and glottis edema in group one were lower than those in group C and group 2, 6 h after surgery (P < 0.05). The pharyngolaryneal VAS in group one was significantly lower than that in group C and group 2 , 6 and 24 h after operation (P < 0.05), but there was no statistical difference between them 48 h after surgery between 3 groups. Conclusions Aerosol inhalation of budesonide after double lumen endobronchial intubation for the patients scheduled for thoracic surgery during early postoperative stage can reduce the incidences of vocal cord congestion and glottis edema, inhibit airway inflammation, significantly reduce the extent of the POST. The effect is better than that of the lateraerosol inhalation of budesonide.
