Objective: To evaluate the effect of Twin-block function al appliance in the treatment of transmissible obstructive sleep apnea syndrome (O SAS). Methods: 7 cases of OSAS, aged 8.6～13.2 years, with sk e letal Angle II malocclusion were treated with Twin-block fuctional appliance fo r 13 months on an average. The position of the mandible, tongue, soft palate,hyo id bone and the radius vector of the upper airway was measured by lateral cepha lometric radiographs, the indexes of sleep condition, breath function and cardio vascular system were measured by polysomnography before and after treatment. Results: At the end of the treatment, the average increase in the radius of upper airway was 4.84 mm (P

Systemic inflammatory response syndrome (SIRS) and its lethal sequela multiple organ dysfunction syndrome (MODS) are common complications in critical illness, such as severe trauma, shock, infection and major operations. During the past three decades, the evolution in our understanding of SIRS and/or MODS could be divided into three stages. Particularly in recent years, advances in molecular and cellular biology have provided new insights in the pathogenesis of this complex condition. The earlier emphasis on the pro inflammatory mediators involved in propagation of inflammatory response, has gradually been replaced by a realization that SIRS/MODS are the result of an imbalance of pro and anti inflammatory mediators to create the final status of excessive inflammation or immunoparalysis'. Though prognosis remains poor, the knowledge that now exists about SIRS/MODS gives great hope for the future. Progress has been made in new treatment modalities and re evaluation of current available measures. Nevertheless, improved techniques to monitor immunological or other markers of inflammatory and host defense responses will be important in assessing the effects of future therapies on central mechanisms contributing to SIRS/MODS.

The research findings published by National Surgical Adjuvant Breast and Bowel Project have continued to change the clinical practice of early-stage breast cancer over the past decade.Sentinel lymph node biopsy has become the new surgical operation standard.The aromatase inhibitor adjuvant endocrine therapy cycle has been extended from 5 years to 10 years, which benefits the patients with high risk and reactivity.Chemotherapy combined with trastuzumab has become the standard adjuvant therapy strategy of human epidermal growth factor receptor-2-positive invasive breast cancer.In addition, the research progress is also related to the optimization of the fields including the postoperative adjuvant chemotherapy and neoadjuvant chemotherapy.

High mobility group A1 belongs to the family of high mobility group. It is widespread in human,and involved in the physiological and pathological situations. It is overexpressed in many human cancers including haematological malignancies as the oncogene.

Objective To summarize the clinical presentation, pathology features, and treat-ment principle for primary testicular non-Hodgkin's lymphoma. Methods Twelve patients were di-agnosed with primary testicular lymphoma. The mean age was 62 years (36-78). Of the patients, unilateral primary testicular tumors were found in 11 cases and bilateral tumors were found in 1 case. All cases had swollen testes, 3 cases had mild pain and 1 had low-grade fever. Ultrasonic examination detected solid mass in all 12 cases. CT scan revealed retroperitoneal enlarged lymph nodes in 3 cases. Nine patients were diagnosed with disease of stage Ⅰ E, 2 of stage Ⅱ E, and 1 of stage Ⅲ E. All of the patients underwent radical orchiectomies. Postoperative treatment included: CHOP chemotherapy for 10 cases, radiotherapy after chemotherapy for 5 cases, and surgery alone for 2 cases. Results Post-operative pathology results were non-Hodgkin's lymphoma in all cases. One patient lost in follow up, one died within 2 years because of other disease. The 1, 3 and 5 year actual survival rates were 82% (9/11) ,40%(4/10),20% (2/10), respectively. The relapsed organs included contralateral testis(3/ 11), central nervous system(3/11), liver(1/11)and retroperitoneal lymph node(1/11). Conclusions The prognosis of the primary testicular non-Hodgkin's lymphoma is very poor. Chemotherapy must be used after surgery for any stage. Stage Ⅰ E and Ⅱ E patient should be treated by surgery combined with radiotherapy and chemotherapy. Contralateral testis should be irradiated prophylactically. Pa-tients beyond stage Ⅱ E should accept chemotherapy after surgery and radiotherapy according to the patient's status.

Objective To detect the changes of interleukin-18 (IL-18) in plasma of trauma patients and evaluate their value in early warning of organ dysfunction. Methods A prospective study was carried out in 54 trauma patients admitted in from March 2001 to September 2002, which were divided into low injury severity score(ISS) group (Group L-ISS) and high ISS group (Group H-ISS). ELISA was applied to measure the level of IL-18 of blood samples that were collected on arrival, at days 4, 7 and 14 following admission. In the meantime, IL-18 level of plasma samples from patients with systemic inflammatory response syndrome (SIRS), sepsis and multiorgan dysfunction syndrome (MODS) was retrospectively analyzed so as to calculate the critical value of IL-18 in predicting organ dysfunction. Results After trauma, IL-18 concentration of plasma reached peak at days 4 and 7, and decreased gradually at day 14, which was significantly related to SIRS, sepsis and MODS, respectively. The IL-18 level was high relatively in plasma from patients with organ dysfunction. The higher IL-18 level in plasma within seven days after trauma indicated the severer organ dysfunction. Conclusion IL-18 is sensitive in early warning of organ dysfunction after trauma.

Objective To investigate the protective effects of extract of Xihuangcao Tea on chemical hepatic injury in mice and rats.Methods Mouse models of chemical hepatic injury were induced by CCl4 and rat models of jaundice by ?-naphthylisothiocyanate(ANIT).Then extract of Xihuangcao Tea was administered and enzyme activity of SGPT in the serum was measured in the mice.The serum level of total billirubin was determined in the rat jaundice models.Results Compared with the models,the enzyme activity of SGPT was significantly reduced and serum total bilirubin level decreased in extract of Xihuangcao tea groups(P

Objective To study the protective effects of aqueous extract and alcohol-soluble extract of Isodon lophanthoides var.gerardianus (Benth.)Hara (ILVG) on immunity hepatic injury induced by concanavalin A (Con A) in mice.Methods One hundred and eight NIH mice were allocated into normal control group,model group,ILVG groups of aqueous extract and alcohol-soluble extract (low-,middle-and high-dosage),and bifendate group randomly.In the experimental groups,mice received either ILVG aqueous extract or alcohol-soluble extract (18.20 g?kg-1,9.10 g?kg-1,4.55 g?kg-1 respectively) or Bifendate (45 mg?kg-1) by gastric perfusion daily for consecutive 5 days.In the 5th day,Con A (20 mg?kg-1) was injected into mice via the tail vein 4h after administration.And then the blood was obtained by picking out the eyeball and the serum was separated after 8-hour fasting.The serum levels of ALT and AST were analyzed,the body weight as well as the weight of liver,spleen and thymus were measured,and pathological features of hepatic tissue were observed.Results ILVG can decrease the ALT and AST,restrain the enlargement of liver and the shrinkage of thymus and reduce the necrosis of hepatic tissue.Conclusion Aqueous extract and alcohol-soluble extract of ILVG possess the effects of protecting liver from immunity injury induced by Con A in NIH mice.
