Objective:To repair unilateral incomplete cleft lip with Noordhoof's incomplete cheiloplasty. To analyze the properties of the technique and to emphasize the key points of the operation design and manipulation. Methods:52 cases of unilateral incomplete cleft lip were received Noordhoff treatment. The characterization of operative method, results and attention were analyzed. Results: 51 cases are totally healed successfully except 1 case is healed successfully by re-operation for losing balance onto the floor. Conclusion: With Noordhoof's surgical technique for unilateral incomplete cleft lip, parenchyma of the lip is utilized mostly, the nosewing outboard incision is avoided. The shape of vermilion is more satisfactory.

OBJECTIVE:To explore the repairing effect and mechanism of Huazhuo jiedu yukui formula on the mucosal dam-age of rats with ulcerative colitis (UC). METHODS:72 rats were randomly divided into blank group,model group,mesalamine group(positive control,0.3 g/kg),Huazhuo jiedu yukui formula low-dose,medium-dose,high-dose groups(5,10,20 g/kg),12 in each group. Except for blank group,other groups were induced UC model. After 4 d of modeling,rats in administration groups received related medicines,ig,blank group and model group received normal saline,ig,once a day,for 2 weeks. After administra-tion,disease activity index(DAI)and mucosal damage index(CMDI)of rats were observed;IL-8,TNF-α contents in serum and cyclooxygenase 2 (COX-2) expression in colon tissue were detected. RESULTS:Compared with blank group,DAI and CMDI scores in model group were increased;IL-8,TNF-α contents in serum were increased;COX-2 expression in colon tissue was en-hanced,with statistical significances (P<0.05). Compared with model group,DAI and CMDI scores in model group were de-creased;IL-8,TNF-α contents in serum were reduced;COX-2 expression in colon tissue was weakened,with statistical signifi-cances (P<0.05). Compared with mesalamine group, the above-mentioned indicators in Huazhuo jiedu yukui formula medi-um-dose,high-dose groups changed more obviously (P<0.05),and effects of Huazhuo jiedu yukui formula showed significant dose-effect relationship. CONCLUSIONS:Huazhuo jiedu yukui formula can improve disease activity status of UC rats and reduce colon mucosal damage,and the effects of medium-dose and high-dose Huazhuo jiedu yukui formula were better than mesalamine, which may be related to reducing inflammatory reaction and inhibiting COX-2 expression in colon tissue.

Objective: To study a new method of alveolar cleft bone grafting. Methods: Group A: 62 cases (74 sides) alveolar cleft patients were transplanted with self-ilium spongy bone. Group B: 26 cases (30 sides) alveolar process patients used autologous ilium combined with DDM. Anterior occlusal radiographs and panoramic oral radiogram were taken before and after the operation to observe if there was new bone formation in the bone grafting area. According to Bergland grade criterion, analyzed the X-ray results after 3 months of the operation. Results: Group A: 17cases(17 sides) in class 1 group(23%), 17 cases(20 sides) in class 2 group(27%), 13 cases(14 sides) in class 3 group (19%), 15 case(23 sides) in class 4 group(31%). The overall survival rate of ABGR was 68.9%, and the clinical success rate was 50 %;Group B:16 cases(16 sides) in class 1 group(53.3%), 7 cases(8 sides) in class 2 group(26.7%), 2 cases(4 sides) in class 3 group (13.3%), 1 case(2 sides) in class 4 group(6.7%). The overall survival rate of ABGR was 93.3%, and the clinical success rate was 80%. Conclusion: Ilium spongy bone combined with DDM is good for alveolar process cleft bone grafting. It is better to use decalcified dentinal matrix of human than autologous ilium spongy bone.

Objective:To investigate the characteristics of implicit memory and its related factors in schizophrenic patients with negative and positive symptoms.Methods:Ninety-three schizophrenic patients (including 52 cases of negative symptoms group and 41 cases of positive symptoms group) and 30 normal controls (normal group) were tested with the method of Chinese character word completion method. The reaction time and correct rate were recorded and compared with analysis of variance and t-test, and the correlation with demographic factors was analyzed with Pearson correlation analysis. Results:Accuracy of implicit memory test in schizophrenia group: there were statistically significant differences in the accuracy of patients with different course of disease (≤5 years: (38±5)%, 5-15 years: (34±8)%, ≥15 years: (34±7)%, P<0.05).The differences were statistically significant in the accuracy of patients with different education levels(primary school: (35±6)%, junior and senior high school: (34±7)%, secondary college education and above: (39±5)%, P<0.05).The accuracy of patients with education years < 10 years ((34±7)%) was significantly lower than those with education years ≥10 years ((37±6)%, P<0.05).Reaction time results of implicit memory test in schizophrenia group : there were significant differences in reaction time of patients with different disease course(≤5 years: (3 248±971)ms, 5-15 years: (3 515±672)ms, ≥15 years: (3 925±842)ms, P<0.05).The differences were statistically significant in the reaction time of workers ((3 495±712)ms), farmers ((3 870±878)ms) and soldiers ((3 024±924)ms, P<0.05).The reaction time of patients with clozapine ((3 869±871)ms) was significantly higher than that of patients with olanzapine ((3 393±626)ms, P<0.05).Intergroup results of accuracy: the accuracy of normal control group ((40±5)%) was significantly higher than that of negative symptom group ((33±7)%, P<0.01).The accuracy of negative symptom group was significantly lower than that of positive symptom group ((37±6)%, P<0.01).Intergroup reaction time results: the reaction time of normal control group ((2 660±667)ms) was significantly lower than that of negative symptom group ((3 678±951)ms, P<0.01) and positive symptom group ((3 072±865)ms, P<0.05).The reaction time of negative symptom group ((3 678±951)ms)was significantly higher than that of positive symptom group( P<0.01).There was significant negative correlation between the accuracy of implicit memory and the course of disease in schizophrenia ( r=-0.22, P<0.05). Conclusion:The implicit memory of schizophrenic patients is related to the course of disease, taking drugs, and occupation.There may have differences in implicit memory between patients with negative and positive symptoms of schizophrenia.
