Résumé
Cleft lip and palate is the most common congenital defects of oral and maxillofacial region in human beings. The etiology of this malformation is complex, with both genetic and environmental causal factors are involved. To provide a better understanding in the genetic etiology of cleft lip or palate, the author summarized recent years studies based on Chinese population. Those researches included validation of some candidate genes for cleft lip or palate, using genome wide association analysis which included six independent cohorts from China to elucidate the genetic architecture of non-syndromic cleft lip with or without cleft palate in Chinese population and finally found a new susceptibility locus. This locus was on the 16p13.3 (rs8049367) between CREBBP and ADCY9. It has been mentioned common methods of genetic analysis involved in the researches on cleft lip or palate in this paper. Furthermore, we try to discuss new methods to illustrate the etiology of cleft lip and palate that could provide more inspiration on future researches.

Objective To study the anxiety and depression in patients with amyotrophic lateral sclerosis(ALS).Method One hundred and seventy-four ALS patients were evaluated by self-rating anxiety scale(SAS)and self-rating depression scale(SDS) to study the anxiety and depression in them.Results In 174 ALS patients,21 had anxiety(12.07%)and 65 the depression(37.36%). The scores of SAS and SDS in the ALS patients were significantly higher than the national norm(P<0.05).The depression incidence in the female patients was significantly higher than the male(P<0.05).Conclusions Anxiety and depression are more severe than those in ALS patients than those in normal people.Psychological support is important for these patients,especially for those female patients.

<p><b>OBJECTIVE</b>To provide basis for effects of an early psychological intervention on parents of children with cleft lip/palate, and investigate the effects of an early psychological intervention to them.</p><p><b>METHODS</b>One self-administered questionnaire (SCL-90) was applied in 102 parents of children with cleft lip/palate, compared to 126 parents of healthy individuals on the day of admission. They were given the psychological intervention during hospitalization and 3 months after discharge. The questionnaire (SCL-90) was again applied to them on the day of discharge and 3 months after discharge.</p><p><b>RESULTS</b>Using the questionnaire (SCL-90), the answer scores of somatization, obsessive-compulsive, depression and anxiety etc. were significantly higher than those of the control group (P < 0.05). There were no statistical differences during 3 subgroups in the case group (P > 0.05). There were no statistical differences on the day of admission and on the day of discharge (P > 0.05), but there were statistical difference on the day of admission and 3 months after discharge (P < 0.05).</p><p><b>CONCLUSION</b>In this study, the psychosomatic states of parents of children with cleft lip/palate is poor.

<p><b>OBJECTIVE</b>To study the periodontal health status of Hui and Han adults in Ningxia Hui autonomous region, thus to provide scientific basis for the establishment of oral health care policies in this region.</p><p><b>METHODS</b>2 628 adults in Ningxia Hui autonomous region were investigated in this study according to the criterion issued by World Health Organization on the basic methods of oral health investigation and China oral health third epidemiological survey protocol. The inspection item included gingival bleeding (bleeding on probing, BOP), dental calculus, probing depth (PD) and attachment loss (AL). SPSS 15.0 statistical software was applied to analyze the results.</p><p><b>RESULTS</b>1) The positive rate of BOP sites, detection rate of calculus and PD were peaked in 36-45 and 46-59 years old, but in the > or = 60 age group rather lower. The prevalence of periodontitis and the percentage of AL > or = 4 mm sites were increased with the adults' age. 2) In addition to the percentage of AL > or = 4 mm sites, the differences of the other indicators between the genders were not statistically significant. 3) The positive rate of BOP sites, detection rate of calculus, PD, the prevalence of periodontitis and the percentage of AL > or = 4 mm sites were higher for the mountain areas than the plain areas. 4) Hui population's positive rate of BOP sites, detection rate of calculus, PD, the prevalence of periodontitis and the percentage of AL > or = 4 mm sites were significantly lower than the Han population in Ningxia.</p><p><b>CONCLUSION</b>The periodontal health status of adults in Ningxia Hui autonomous region is associated with age, gender, nationality and region.</p>

Objective:To study the association between the rs2013162 and rs2235375 polymorphisms in IRF6 and risk of NSCL/P in west Chinese population. Methods: The study group consisted of 332 NSCL/P patients, their parents (289 mothers, 243 fathers and 206 complete families), and 174 controls. PCR-RFLP method was used to identify genotypes and both case-parent and case-control designs were carried out on samples from west China. Results: There were significant differences in the frequency distributions of both genotypes and alleles when cases were compared with control infants at the rs2235375(P<0.01, P<0.01 respectively). We found strong evidence of over-transmission of the G allele at rs2235375 in cleft case-parent trios(P<0.01). Five specific haplotypes showed significant over-and under-transmission. Conclusion: These results suggest IRF6 variants play a role in NSCL/P in west Chinese populations.

Objective:To evaluate the effectiveness of individual operative design for unilateral cleft lip repair.Methods:Individual operation design was applied for the repair of unilateral cleft lip in 40 cases.The operations were conducted according the designs and the secondary nasal deformities were corrected at the same time.One week after operation,dermal sutures were removed,the effects were evaluated by 3 professional doctors.7 labial morphometric lines were measured.The ratio of the line length on healthy side to the correspondence on the cleft side(RLL)were calculated for objective evaluation.Results:First intention was found in all cases,the labial bow of both sides was symmetried after operation.In dynamic state and static state,the effects of the operations were satisfactory.RLL of 0.91-1.10 of the 7 lines was observed in 67.5%-95.0% of the patients.Conclusion:The individual operation design is feasible for unilateral cleft lip repair.

Objective:To explore the therapeutic efficacy of a new access to internal rigid fixation for mandibular condylar fracture. Methods: 7 patients with 9 unilateral mandibular condylar fractures were treated with preauricular beeline incisions. The two trunks of facial nerve were dissected and separated along the surface of the superficial temporal veins. Mandibular ramus periosteum was dissected. The fracture segments were reduced and fixed under sufficient exposure. Results: This operation access provided a sufficient exposure and was convenient for reduction and fixation. All the patients recovered effectively.Conclusion: This surgical approach is one of the feasible methods for reduction and fixation of mandibular condylar fracture.
