OBJECTIVEThis study aimed to observe the postoperative pain rate and degree of pain in preschool children with cleft lip and palate, and investigate the effect of nursing intervention on pain relief.

METHODSA total of 120 hospitalized cases of three- to seven-year-old preschool children with cleft lip and palate were selected from May to October 2011. The subjects were randomly divided into the control group and experimental groups 1, 2, and 3. The control group used conventional nursing methods, experimental group 1 used analgesic drug treatment, experimental group 2 used psychological nursing interventions, and experimental group 3 used both psychological nursing intervention and analgesic drug treatment. After 6, 12, 24, and 48 h, pain self-assessment, pain parent-assessment, and pain nurse-assessment were calculated for the four groups using the pain assessment forms, and their ratings were compared.

RESULTSThe postoperative pain rates of the four groups ranged from 50.0% to 73.3%. The difference among the four groups was statistically significant (P < 0.001). The differences among the control group and experimental groups 1 and 2 were not statistically significant (P = 0.871), whereas the differences among experimental group 3 and the other groups were statistically significant (P < 0.001).

CONCLUSIONPostoperative pain in preschool children with cleft lip and palate is common. Psychological nursing intervention with analgesic treatment is effective in relieving postoperative pain.

OBJECTIVE: To investigate the genetic causes of nonsyndromic deaf patients in special educational school of Chifeng city. Inner Mongolia by genetic screening testing method. This study focused on analyzing mutations of coding sequence of GJB2, GJB3 and GJB6 gene. METHOD: DNA were extracted out from peripheral blood of 134 nonsyndromic deaf probands of Chifeng special educational school and 100 normal hearing controls in northern China. First, GJB2 gene mutation was analyzed by direct sequencing for its only exon in the open reading frame. Individuals found with heterozygous GJB2 mutation were given further testing for GJB6 del(GJB6-D13S1830) and direct sequencing for its exon. In 91 probands with unknown genetic cause (excluding probands who carried mtDNA A1555G mutation and GJB2 gene bi allele mutation and probands who were diagnosed as enlarged vestibular aqueduct by temporal CT), GJB3 gene mutation was analyzed by direct sequencing for its exon. RESULT: The sequencing results revealed that forty-one cases carried GJB2 mutation. of which twenty-two were homozygous or compound heterozygous and nineteen were heterozygous. Further testing for GJB6 del(GJB6-D13S1830) and analysis of its coding sequence in GJB2 heterozygous cases showed no positive result. Four subjects in control group carried pathogenetic mutation of GJB2 gene. Six types of novel variants of GJB2 gene were detected. Of the 91 deaf probands with unknown etiology. two probands were found carrying heterozygous pathogenetic mutation of GJB3 gene. one of whom also carried GJB2 235delC heterozygous mutation. One subjects in the control group carried pathogenetic mutation of GJB3 gene. Three types of novel variants of GJB3 gene were found. CONCLUSION By screening GJB2.GJB3 and GJB6 gene, we found 32.1% probands carrying GJB2, GJB3, and GJB6 mutations and we are able to determine genetic cause related to these three genes from one family for 16.42 percent of nonsyndromic deaf probands in special educational school of Chifeng city. The discovery of novel variants of GJB2 and GJB3 gene makes the mutational and polymorphic spectrum more plentiful in Chinese population.

Qingweisan is one of the classical prescriptions commonly used in the treatment of oral diseases. By means of Bibliometrics， the authors collected the ancient books on Qingweisan and sifted out 411 valid data， involving 116 classics of traditional Chinese medicine. The historical origin， drug composition， indications， principle of composition， dosage，and preparation of Qingweisan were statistically analyzed， and it was found that the prescription originated from the Treatise on Spleen and Stomach（《脾胃论》） by LI Dongyuan and is composed of Rehmanniae Radix， Angelica Sinensis， Cortex Moutan， Coptidis Rhizoma and Cimicifugae Rhizoma， with the functions of clearing stomach， purging fire， cooling blood and dispersing depression. And Qingweisan was mainly used to treat toothache， headache， and preference for cold and aversion to heat caused by "excessive heat in yang brightness meridian". There were 352 indications recorded， most of which followed LI Dongyuan's theory and the expanded indications reached 70 kinds. Specifically， toothache （132） was the most， accounting for 22.49% of the total indications， followed by headache （60， 10.22%）. In addition， Qingweisan was widely used in modern clinical practice for multiple system diseases， among which oral system （197） was dominant， accounting for 72.69%， followed by skin system （28， 10.33%） and digestive system （27， 9.96%）. Although the indications were wide， the pathogenesis always belonged to "upward attack of stomach fire". Through the excavation and statistical analysis of the ancient books on Qingweisan and its modern clinical application， the authors aimed to provide a more scientific reference for the research and application of classical famous prescriptions.
