The penal stipulation to the subject range about crime of illegal medical practice is too narrow,and there is also a great deal of contradictory regulation between Criminal Law and Practicing Physicians Law so it can not achieve the legislation goal.It is essential to revise the 1st section of "Criminal law "336th in order to expand the subject range and standardize the medical service market of our country.

Oculo-auriculo-vertebral spectrum (OAVS), also known as Goldenhar syndrome, hemifacial microsomia, oculo-auriculo-vertebral dysplasia and facio-auriculo-vertebral spectrum, is a developmental disorder associated with the first and second branchial arches. Most cases are sporadic, while some familial instances observed suggested that the etiology of OAVS heterogeneous. In this review, we summarize the OAVS epidemiology, classification and mainlyheterogeneous etiology.

Treacher Collins syndrome (TCS, OMIM 154500), also known as Franceschetti-Klein syndrome, is a rare disorder that affects the first and second branchial arches. The estimated incidence is 1/50 000 live births. Mutations in TCOF1 (78%-93%) and POLR1C or POLR1D (8%) cause the disease. Most of TCS cases are inherited in a dominant pattern, while a small proportion are inherited in a recessive pattern. TCS has a variable phenotype with typical clinical characteristics including downward-slant of palpebral fissure, malar hypoplasia, mandibular hypoplasia and microtia. TCS management is a multidisciplinary affair, as interventions range from reconstructive to psychosocial. For hearing rehabilitation, TCS patients may have the choices of BAHA, ponto, vibrant soundbridge or bonebridge implantation. In this review, we summarize the TCS clinical malformations, diagnosis, genetics, management and auditory rehabilitation.

BACKGROUNDCytochrome P450 2E1 (CYP2E1) has an important role in the metabolic activation of precarcinogens such as N-nitrosoamines and other low relative molecular mass, organic compounds. This study examined whether CYP2E1 RsaI and DraI polymorphism are associated with susceptibility to esophageal squamous cell carcinoma and the correlation between the genotypes and expression levels of CYP2E1 mRNA.

METHODSSeventy-seven patients with newly diagnosed, untreated esophageal squamous cell carcinoma and 79 healthy controls matched in age, gender and residence were recruited for the control study. An RsaI polymorphism in the 5'-flanking region and a DraI polymorphism in the sixth intron of the CYP2E1 gene, which could possibly affect its transcription, were determined in this study by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and mRNA level of CYP2E1 was measured by quantitative real-time reverse transcription PCR.

RESULTSNo significant association of RsaI or DraI polymorphism of CYP2E1 with susceptibility of esophageal squamous cell carcinoma were demonstrated (OR = 1.67, 95% CI: 0.89 - 3.15, P = 0.11; OR = 1.11, 95% CI: 0.59 - 2.09, P = 0.74, respectively). With SHEsis software, no linkage disequilibrium was detected between RsaI and DraI polymorphism (D' = 0.528, r(2) = 0.27). When combined RsaI polymorphism with DraI polymorphism, the association between that carrying c2 allele and DD genotype and the risk for esophageal squamous cell carcinoma were found (OR = 5.77, 95% CI: 1.65 - 20.22). Compared with the normal controls, the mRNA levels with RsaI polymorphism, DraI polymorphism, or any combined genotypes in cases showed no statistical difference.

CONCLUSIONSThis study suggests that carrying c2 allele and DD genotype conferreded an elevated risk for esophageal squamous cell carcinoma. There was no significant statistical relationship between the genotypes c1/c2, D/C, or the combined allele and mRNA expression.

Objective To investigate the current status about nursing undergraduate students' knowledge,attitude and practice (KAP)regarding nosocomial infection.Methods The self-administered questionnaires were employed to survey 108 undergraduate nursing students on the basis of a simple random sampling method.Results In the knowledge dimension,the nursing students earned 78.3％ of accuracy rate when responding to the questionnaires.The students also demonstrated positive attitudes towards nosocomial infection and occupational safety,particularly the female students.In terms of practice,the students performed relatively poor as 36.1％ of the students were unclear about the classification of medical garbage and 22.2％ of the students used their non-clean hands to touch their eye-glasses.Conclusions The undergraduate nursing students have demonstrated adequate knowledge and proper attitude towards nosocomial infection and occupational safety,however,some behaviors need to be changed.Nursing schools and hospitals should be aware of these findings and provide more training programs regarding nosocomial infection and occupational safety so that they can help students formulate good habits to prevent and control nosocomial infection.

OBJECTIVE: To observe the expression of IL-9, IL-17 and Foxp3 in nasal polyps,so that to explore the role of Th9, Th17/Treg cells imbalance in pathogenesis of nasal polyposis. METHOD: Forty cases of nasal polyps and 20 cases of normal middle turbinate mucosa (controls) were involved in this study. The expression patterns of IL-9, IL-17 and Foxp3 were detected by immunohistochemistry. RESULT: The positive rates of IL-9 and IL-17 in nasal polyps tissues were respectively 75.0% and 80.0%, which were both significantly higher than those in the controls (positive rates were 35.0% and 50.0%, respectively), but the Foxp3 expression was downregulated in nasal polyps tissues (37.5%) compared to the controls (80.0%), P < 0.05 respectively. CONCLUSION The cytokines IL-9 and IL-17 are obviously involved in the occurrence and development of nasal polyposis, suggesting remarkable infiltration of Th9 and Th17/Treg imbalance exist in nasal polyps, both of which may play important roles in pathogenesis of nasal polyposis.

OBJECTIVE: To investigate the expression levels of Th9, Th17 and Treg cells in peripheral blood of patients with chronic rhinosinusitis with nasal polyps (CRSwNP), and explore the role of Th9, Th17 and Treg cells in the progression of CRSwNP. METHOD: Forty-six cases with CRSwNP served as an experimental group, while 22 cases with simple nasal bleeding or nasal septum deviation served as a control group. The peripheral blood of patients in both groups was collected and analyzed. (1) Using flow cytometry (FCM) to detect the expression rates of Th9, Th17 and Treg cells in peripheral blood. (2) Using qRT-PCR to detect the expression of relevant transcription factor of Th9, Th17 and Treg cells (IL-9mRNA, PU. 1, IRF-4, RoRc, and Foxp3). (3) Using SPSS16.0 to analyse the differentiations and the revelance among these three cells. RESULT: (1) The expression rates of Th9 and Th17 cells in patients with CRSwNP (1.29% ± 0.18%, 4.03% ± 0.69%) was higher than the control group (0.45% ± 0.14%, 1.35% ± 0.26%). But the expression rates of Treg cells in the experimental group (2.98% ± 0.13%) was significantly lower than the control group (5.44% ± 0.57%). The differences were statistically significant (P < 0.05). (2) The expression of revelant transcription factor (IL-9mRNA, PU.1, IRF-4, RoRc) in NP group was also higher than the control group. The expression of Foxp3 in the control group was higher than NP, the differences both were statistically significant (P < 0.05). (3) The difference between Th9 and Th17 in patients with NP was not significant (P > 0.05), and the negative correlation was found between Th17 and Treg (r = -0.549, P < 0.05). CONCLUSION The high expression level of Th9 and Th17 cells might promote the development of NP, whereas the low expression level of Treg cells might further aggravate the occurrence of NP. The main function of the imbalance of Th17/Treg cells may be immune regulation in the pathogenesis of nasal polys.

Objective: In order to elucidate the carotenoid metabolic pathway in Pogostemon cablin, a phytoene desaturase (PDS) of P. cablin (PcPDS1) gene was cloned and analyzed bioinformatically. Methods: The full length PDS gene sequence was retrieved from transcriptomic database of P. cablin, the full length primer was designed for PCR verification, and PcPDS1 gene was analyzed using several bioinformatical softwares. Results: PcPDS1 (NCBI accession, KC854409) contained 1960 bp length of open reading frame (ORF) and encoded 569 amino acids postulated. Additionally, the physical and chemical properties of PcPDS1-coded protein were analyzed by bioinformatical softwares. Phylogenetic analysis showed that PcPDS1 was tightly clustered with PDS genes in Gentiana lutea, Nicotiana tabacum, and Ipomoea batatas, which is consistent to the phylogenetic relationship of species. Conclusion: PcPDS1 is successfully coloned and molecularly characterized.
