Objective To compare the influence of two different managements of relief incision (exposed relaxation therapy or absorbable hemostatic gauze) in infants' palatoplasty. Methods A total of 118 infants with cleft palate between 5- to 8-month-old for the study were randomly divided into two groups: group A was exposed therapy group, and in group B both sides of relief incision were placed absorbable hemostatic gauze. The wound bleeding, body temperature, diet and incidence of fistula were observed and analyzed after operation. Results There was no significant difference between the two groups in postoperative temperature, diet and wound healing (P>0. 05). The postoperative wound bleeding was statistically significant differences between the two groups (P<0. 05). Conclusions Either exposed therapy or placed absorbable hemostatic gauze in relief incision, has minimal systemic and local reactions in the postoperative infant. The advantages of exposed treatment are economic and simple, and less irritant to the wound.

Objective To investigate the surgical correction of alar deformity and repairing function of unilateral cleft lip in infant. Methods Millards procedure was used to incise skin, muscle and mucosa, correct the nasal deformity through lip. At the normal side, ophthalmic scissors was applied to incise lips muscle and skin, and reach the deep level of the base of nasal pillor, cut the abnormal attachment between the orbicular muscle of mouth and anterior nasal spina, and sharp dissect cartilage and skin in nasal wing through deep level of nasal pillor. At the cleft side, the abnormal muscle branch was cut that attached at the down side of the base of nose and pyriform aperture, the tissue between nasal base and lip, maxilla relaxed, and the cartilage and skin in the nasal wing at the same side dissected. The deform cartilage was repairied as the same of normal side. After the rehabilitation of cartilage of nasal wing, the soft tissue at deep level was moved to normal location, but the deep level structure of nasal wing cartilage, nasal septum cartilage and nasal bone did not dissected. After the dissection of orbicular muscle of mouth, the muscle in nose and lip must be relaxed in illous side. The orbicular muscle of mouth was sewed under the condition of tensionless. The repairing of orbicular muscle of mouth will improve the balance of muscular strength around the nose. Thus, the deviation of nasal pillor was corrected and the base of nose repaired. Results Eighty cases of infant with unilateral cleft lip at the age of 3 months ～12 months, in which 11 cases were Ⅰ?,16 Ⅱ, and 3 Ⅲ?. Eighty cases were low grade alar deformity, and 13 middle grade deformity. After operation, 52 cases were better, 17 cases were good, and 11 cases were worse. The postoperational result was good. Conclusion While performing the cleft lip operation or Millard operation, the authors can correct the nasal deformity through lip. So, it is recommended that cleft lip and the alar deformity can be repaired at the same time.

AIM: IL-12 acts upon T lymphocytes and activates its receptor complexes of ?1/?2 ,and so IL-12 can regulate TH1/TH2 balance. Our study is aimed at IL-12-inducing apoptosis of T cells and expression and signal transduction of Fas/FasL during T cell apoptosis. METHODS: The apoptosis of T cells was detected by Annexin V staining cytometry and the expression of Fas/FasL under different inhibitors were detected by semi-quantitative PCR. RESULTS: IL-12 induced the human leukemic T cell line(TIB-152) and the human lymphoma T cell line(HTB-176) and the normal human T cells to undergo apoptosis. The FasL expression at 6 hours after treatment with IL-12 increased apparently, and reached the max at 24 hours, and FasL expression induced by IL-12 was inhibited by PKC inhibitor. But IL-12 did not influence Fas expression. CONCLUSIONS: IL-12 can induce T cells to undergo apoptosis which is characterized by early membrane changes, the inducing effect is correlated with the concentration of IL-12 and the maturation of T cells. FasL participates in the progression of T cell apoptosis as a apoptosis mediator, and the effect of IL-12 on FasL expression may be related with PKC pathway.

Objective The purpose of this study was to evaluate the outcome of autogenous bone grafts in unilateral cleft lip and palate patients following early orthodontic tooth movement,and to determine the volume of new bone formation in the bone grafted region with spiral computed tomography.Methods Computed tomography scans of 12 patients were taken immediately preoperatively and at 6 months postoperatively.The patients underwent bone grafting between 9 and 13 years of age were divided into two groups based on whether postoperative orthodontic tooth movement were initiated or not.Three-dimensional models were created in each period,and the defect of alveolar cleft and volume of the newly formed bone were calculated in each patient.The roots of the moved teeth and their positions to the alveolar bone were also observed.Results The preoperative cleft width and cleft volume were not significantly different between both groups.The volume of the newly formed bone in group A was (0.98±0.23) mm3,significantly higher than that in group B,which was (0.73± 0.15) mm3.The rate of newly formed bone in group A was (72.5 ± 11.9)％,significantly higher than that in group B,which was (53.2±9.7)％.The cleft adjacent teeth could move smoothly into the bone grated area,with no root resorption observed in the computed tomography scans.Conclusions Early orthodontic tooth movement can reduce bone resorption in autogenous bone grafted unilateral cleft lip and palate patients through the observation of spiral computed tomography.It plays an active role in the bone remolding process after bone grafting.

AIM: IL-12 acts upon T lymphocytes and activates its receptor complexes of ?1/?2 ,and so IL-12 can regulate TH1/TH2 balance. Our study is aimed at IL-12-inducing apoptosis of T cells and expression and signal conduction of Bcl-2 during T cell apoptosis. METHODS: The apoptosis of T cells was detected by Annexin V staining cytometry and the expression of Bcl-2 under different inhibitors were detected by the method of semi-quantitative PCR. RESULTS: IL-12 can induce the human leukemic T cell line(TIB-152) and the human lymphoma T cell line(HTB-176) and the normal human T cells to undergo apoptosis. The Bcl-2 expression at 6 hours of treatment with IL-12 increased aparently,and reached the max at 24 hours. But IL-12 did influence Bcl-2 expression. IL-12 can induce T cells to undergo apoptosis which is characterized by early membrane changes. CONCLUSION: The inducing effect is correlated with the concentration of IL-12 and the maturation of T cells. Bcl-2 takes part in the progression of T cells' apoptosis as a apoptosis mediator.

AIM: To illustrate the expression of hypermethylation p15 gene in 53 non-Hodgkin’s lymphoma (NHL). METHODS: The methylation of p15 gene in 53 cases of non-Hodgkin’s lymphoma was detected by using methylation-specific PCR (MSP) technique.
