Objective: To annually quantify the condylar growth from 7.5 to 15.5 years and identify the growth direction of condyle during the same period of time.Methods: The sample was obtained from Mathew's implant study with longitudinal cephalometric records of 13 untreated Class I subjects (8 Females, 5 Males). The cephalograms were taken annually from 7.5 to 15.5 years old. Reference lines were constructed based on three implants in mandibular corpus and linear and angular measurements performed. Results:It was found that the greatest amount of bone apposition at points of condylion and superior condylion occurred during the ages of 11.5 years to 12.5 years with the average value of (3.61?2.58) mm and (3.28?2.17) mm, respectively. The largest amount of bone addition at point of posterior condylion occurred much earlier between 8.5-9.5 years old, with average value of (1.92?1.16) mm. CRO angle was constantly decreased during the observation period. Conclusions:The current findings suggest that the condyle grows in forward and upward direction.

Objective • To investigate the effects of dexmedetomidine combined with sufentanil in patient-controlled intravenous analgesia (PCIA) of puerperae with severe preeclampsia after cesarean section. Methods • A total of 250 puerperae with severe preeclampsia who prepared to be treated by cesarean section were divided into observation group and control group by the random number table method with 125 cases in each group. They were given PCIA after operation. The PCIA formula for the observation group was dexmedetomidine combined sufentanil while that for the control group was sufentanil alone. The heart rate (HR) and mean arterial pressure (MAP) were compared between the two groups at different time points. Scores of visual analogue scale (VAS) and Ramsay sedation scale (RSS), the dosage of sufentanil and adverse drug reactions in both groups were recorded at 4, 8 and 24 hours after operation. Results • The HR and MAP of the observation group were significantly lower than those of the control group at 4, 8 and 24 hours after operation (all P<0.05). VAS scores in the observation group were significantly lower than those in the control group while RSS scores were significantly higher than those in the control group. The dosage of sufentanil was significantly less than that in the control group at 4, 8 and 24 hours after operation (all P<0.05). The incidence rates of nausea and vomiting in the observation group (12.80% and 7.20%) were significantly lower than those in the control group (32.00% and 16.00%) (all P<0.05). Conclusion • Compared with sufentanil alone, dexmedetomidine combined with sufentanil not only can significantly enhance the analgesic and sedative effects, but also can significantly reduce the dosage of sufentanil, and reduce adverse drug reactions in PCIA of puerperae with severe preeclampsia after cesarean section.

Objective To analyze the clinical feature, diagnosis, treatment a nd prognostic factors of primary lymphoma of the small bowel. Methods From Apr il 1989 to May 2002, 33 patients with non-Hodgkin's lymphoma of the small bowel were analyzed retrospectively. The Ann Arbor stages were: ⅠE 12, ⅡE 15 and Ⅳ E 6. The histological subtypes were: T-cell lymphoma 1 and B-cell lymphomas 32. A ll the patients received surgical treatment including radical or palliative rese ction. Twenty-six patients received postoperative radiotherapy including strip -f ield technique in 12 and opposed anterior-posterior fields in 14, with a median dose of 2543.5?cGy. Postoperative chemotherapy were applied to all patients inclu ding CHOP regimen in 17, COMP regimen in 6, COP regimen in 3, MINE regimen in 2, COPP regimen in 3 and BACOP regimen in 2. The median number of cycle was 4. Results The overall 5-year survival rate and disease-free survival rate were 48% and 39%. The 5-year survival rates were: ⅠE stage 42%, ⅡE stage 67% and ⅣE s tage 17%, respectively. Conclusions Most of the primary non-Hodgkin's lymphoma of the small intestine are in stage ⅠE and ⅡE, and the intermediate-grade and h igh-grade pathological subtypes are predominant. Surgery based combined treatme n t is effective and is advised. Radiotherapy and chemotherapy may improve the sur vival.

OBJECTIVE To investigate spectrum distribution of pathogens in patients with artificial airway and analyze their associated factors.METHODS The clinical data of 27 patients with tracheal intubation or tracheotomy from Mar 2005 to Mar 2006 were analyzed retrospectively.RESULTS Twenty seven patients were diagnosed as pneumonia.A total of 384 isolates of pathogens were collected from 258 sputum culture.The most were Gram-negative bacilli(293 isolates),and then were Gram-positive cocci and fungi.The four most pathogens were Pseudomonas aeruginosa,Stenotrophomonas maltophilia,meticillin-resistant Staphylococcus aureus(MRSA) and Acinetobacter baumannii.More multiple drug resistant(MDR) pathogens were detected in patients two weeks after intubation or tracheotomy than that after one week,and it was the same with sensitive rates to antibiotics of G-bacilli.CONCLUSIONS Patients with artificial airways have a higher morbidity of MDR pathogens and longer retention time of artificial airway can increase infection of MDR pathogens of lower respiratory tract.

Objective To study the effect of different concentrations of pravastatin treatment on macrophage polarity in mice .Methods The mice bone marrow sources of macrophages were cultured in vitro ,with the 0μmol/L sodium pravastatin group as control ,by giving 10 ,25 ,50μmol/L sodium pravastatin to conduct the drug intervention for 24 h .The enzyme linked immunosor-bent assay (ELISA) was used to detect the secretion of interleukin 10 (IL-10) and IL-12;the flow cytometry instrument was used to detect cell membrane CD16/32 ,CD206 expression;real time quantitative polymerase chain reaction (RT-qPCR) was adopted to detect toll-like receptor 4 (TLR4) ,myeloid differentiation factor 88 (MyD88) ,interferon regulatory factor 5 (IRF5) mRNA expres-sion .Results After the intervention of pravastatin sodium on macrophages ,as the pravastatin sodium concentration increase ,the expression of IL-12 and CD16/32 was decline ,while the expression of IL-10 and CD206 was risen ,which was accompanied by TLR4 ,MyD88 ,IRF5 mRNA expression down regulatyion ,and a dose dependent manner .Conclusion Sodium pravastatin promote the polarization of macrophages toward an anti-inflammatory macrophage phenotype (M2) ,this effect may be related with the anti-inflammatory effect of sodium pravastatin .
