Objective To introduce a surgical procedure resulting in less scars for unilateral microform cleft lip.Methods A Z-plasty incision was designed at suffered agger nasi,and then subcutaneours dissection of suffered upper lip and basis nasi was performed.Releasing suffered alar nasi base from maxillary bone by partly severing the mesculus compressor naris,an orbicularis oculi flap was formed and fixed to the hypodermis of columella base for advancing to superior medial position and overlaying orbicularis oculi.The labial frenulum extension and vermillion submucoustissue flap plicature for filling incisura were carried out to correct the deformitiy of vermillion incisura.Results After 6-18 months follow-up,the wounds of 7 cases (aged 7-19 years) healed at the first grade.The deformity of unilateral subcutaneous celft lip,such as the agger nasi and vermillion incisura,widened nostril,and deficient abial height,was significantly improved.Conclusions Unilateral subcutaneous celft lip could be satisfactorily reconstructed by the surgical technique consisting of Z-plasty incision at agger nasi,orbicularis oculi flap advancing,labial frenulum extension and vermillion submucous tissue flap plicature,with less scar formation.

OBJECTIVE: This study was designed to explore the risk factors associated with severity of juvenile onset recurrent respiratory papillomatosis. METHOD: A retrospective study was conducted to study determinants of severe forms of juvenile recurrent onset respiratory papillomatosis. The patients were separated into different groups based on the onset age, the first recurrence of age, the first recurrence of period, gender and incision of tracheal respectively. The relationship among the lesion severity score,the involvement of the subregion, operation period and the next operation period were also explored. RESULT: It was observed that some children who recurred before 4 years old required more surgery, shorter operation period(the average, longest or shortest operation period) than those elder children, the differences were statistically (P=0. 029, 0. 003, 0. 010, 0. 039, respectively). The severity score of lesion was correlated positively with the involvement of the subregion and negatively with operation period (r=0. 914, -0. 451, respectively). Some children who diagnosed before 4 years old had to endure more severity score and shorter operation period than those older children, the differences were statistically (P= 0. 036, 0. 000, respectively). 8 cases accepted incision of tracheal, they accepted more surgery too. But the differences in the onset age, the first recurrence of age, and the operation period were not statistically. CONCLUSION The results showed that the clinical course of juvenile onset recurrent respiratory papillomatosis was closely related to the first recurrence age and period, while the severity of disease was associated to the onset age and the involvement of the subregion.

OBJECTIVE: To explore the relationship between serum IL-4, IFN-gamma, IL-10 levels and the aetiology of juvenile-onset recurrent respiratory papillomatosis. METHOD: Serum IL-4, IFN-gamma, IL-32 levels of 15 JORRP children were detected by use of enzyme-linked immunosorbent assay (ELISA) and compared with those of healthy control group. RESULT: Serum IL-4 levels were significantly higher in the JORRP children (P<0.01): (524.65 +/- 147.77)pg/ml in the JORRP children and (213.27 +/- 87.48) pg/ml in the healthy control group. Serum IFN-gamma levels were significantly lower in the JORRP children (P<0.01): (2.87 +/- 0.84) pg/ml in the JORRP children and (10.63 +/- 5.09) pg/ml in the healthy control group. Serum IL-32 levels were significantly lower in the JORRP children (P< 0.01): (2.47 +/- 1.60) pg/ml in the JORRP children and (9.08 +/- 2.66) pg/ml in the healthy control group. CONCLUSION 1) While the concentration of Th2 like cytokine IL-4 in children with JORRP was higher than that in control group, the concentration of Th1 like cytokine IFN-gamma in children with JORRP was lower than that in controls, indicating that the polarization of Th1 /Th2 T cell in children with JORRP; 2) The polarization of Th1/Th2 T cell may cause the reduction of the serum IL-32 as a proinflammatory role in host immunity system that could not eradicate HPVs because of lacking enough inflammatory stimulation.

PURPOSE: Allergic rhinitis (AR) has become a global issue for a large part of the general population. Sublingual immunotherapy (SLIT) has been used extensively to treat persistent allergic rhinitis (PAR). Although systematic reviews have confirmed the effectiveness of SLIT for the treatment of AR, a considerable number of studies using extracts of house dust mites (HDMs) for immunotherapy found no consensus on basic treatment parameters and questioned the efficacy of SLIT. METHODS: In this study, we evaluated SLIT for PAR by a meta-analysis of randomized controlled trials (RCTs). Medline, Embase, and Cochrane Library database searches were performed for RCTs on the treatment of PAR by SLIT that assessed clinical outcomes related to efficacy through May 2016. Descriptive and quantitative information was abstracted. An analysis was performed with standardized mean differences (SMDs) under a fixed or random effects model. Subgroup analyses were performed. Heterogeneity was assessed using the I2 metric. RESULTS: In total, 25 studies were eligible for inclusion in the meta-analysis for symptom scores and 15 studies for medication scores. SLIT was significantly different from the controls for symptom scores (SMD=1.23; 95% confidence interval [CI]=1.74 to 0.73; P<0.001). For medication scores, significant differences for SLIT were also observed versus the controls (SMD=-1.39; 95% CI=-1.90 to -0.88; P<0.001). CONCLUSIONS: Our meta-analysis indicates that SLIT provided significant symptom relief and reduced the need for medications in PAR. In this study, significant evidence was obtained despite heterogeneity with regard to the use of mite extract. Specifically, the mite extract used was provided by the patients with PAR. Furthermore, to confirm both the objective outcomes and the effective doses of HDM allergen extracts, experimental data should be obtained from large high-quality population-based studies.

OBJECTIVETo investigate the correlation between nonsyndromic deafness and mitochondrial 12s rRNA A839G mutation.

METHODSAccording to the clinical manifestations of mitochondrial DNA sequencing and analysis to find and determine family containing mitochondrial 12s rRNA A839G mutation. Harvested its family members blood and transferred their lymphocytes into lymphoblastoid cell lines, followed by cells cultured, cell doubling experiment, susceptibility testing, cellular oxygen consumption rate experiment, ROS and mitochondrial membrane potential experimental tests were progressed to explore the correlation between the A839G mutation and nonsyndromic deafness.

RESULTSThe mitochondrial 12s rRNA A839G mutation pedigrees were determined through the full sequence detections of the Mitochondrial DNA, further phylogenetic analysis showed that 839 point conservative index (CI) up to 78.6%; in RPMI-galactose medium containing A839G gene mutant cell line, the doubling time was significantly longer than the control group, and the difference was significant (P = 0.033). The effect to cell lines containing the A839G mutation of aminoglycoside drugs was not obvious. When compared with the control group, cell lines containing the A839G mutation significantly reduced cellular oxygen consumption rate(P = 0.033); compared with the control group, the ROS levels of cell lines containing the A839G mutation appeared more substantial elevated with significan difference (P < 0.01). The mitochondrial membrane potential of cells of experimental group was significantly reduced than the control group.

CONCLUSIONThe present study proved that the mitochondria 12s rRNA A839G mutations affect the function of the mitochondrial respiratory chain at the cell level, which might reduce the growth rate of the mutant cell lines, result in hearing.

OBJECTIVE To study on the influence of human papilloma virus(HPV) type on the clinical course of juvenile onset recurrent respiratory papillomatosis(JORRP).METHODS Fresh tumor specimens of 38 patients were collected and the HPV type of the specimens was detected by flow fluorescent hybridization method.According to the results,children were divided into HPV6 and HPVll positive groups.The clinical data of the two groups were compared.RESULTS Among 38 children with recurrent respiratory papillomatosis,21(55.2％) were infected with HPV6,14(36.8％) were infected with HPVll,and 3(7.9％) were negative for HPV 6 or HPV 11.The proportion of aggressive cases in HPV6 and HPV11 groups were similar.The age of onset,preoperative clinical symptom score,number of anatomic locations,anatomic Derkay/Coltrera score and Dikkers score were significant different between the two groups (P=0.002,0.040,0.023,0.001,0.005,respectively).CONCLUSION JORRP patients with HPV11 infection had the features of smaller onset age,more severe clinical symptoms and broader invasion compared with HPV6 infection.

OBJECTIVE To compare the effect of intranasal corticosteroids-gelatin sponge and saline-gelatin sponge in the treatment of nasal adhesion.METHODS A total of 208 noses(170 patients) with nasal adhesions after receiving the endoscopic sinus surgeries from July,2012 to December,2015 were selected.All the cases were divided randomly into two groups:the treatment group and the control group.Both groups received separation treatments of the nasal adhesions.The intranasal corticosteroidsgelatin sponges were used as the separation material for the treatment group,while saline-gelatin sponges for the control group.The severity score and the time of treatment were evaluated as the indicators for curative efficacy of the treatment in each case.The differences of efficacy between two groups were analysed statistically.RESULTS The severity scores of the two groups after the treatment were both substantially lower than those before the treatment;The after-treatment severity scores of the treatment group were significantly lower than those of the control group;the times of treatment in the treatment group were substantially lower than those of the control group.The differences stayed for 3 months,and they became insignificant after 3 months.CONCLUSION The intranasal corticosteroids-gelatin sponge can be a quicker and more effective treatment of nasal adhesion in comparison with saline-gelatin sponge.

Objective:To explore any effect of repeated transcranial magnetic stimulation (rTMS) on the upper limb motor function and cerebral cortex activation of stroke survivors.Methods:Sixty stroke survivors were randomly divided into an intervention group and a control group, each of 30. In addition to routine rehabilitation training (including drug therapy, comprehensive hemiplegic limb training and physical factor therapy), the intervention group received 15 minutes of rTMS daily, five days a week for 4 weeks while the control group was given false rTMS. Upper limb motor function was evaluated before and after the treatment using the Fugl Meyer upper limb motor function rating scale (FMA-UE). Functional near-infrared spectroscopy was used to detect and compare the activation (β values) of the prefrontal cortex, the motor cortex and the primary somatosensory cortex in the 2 groups. The correlation between the FMA-UE scores and the β values was quantified.Results:①There was no significant difference in the average FMA-UE scores between the two groups before the treatment. Afterward, though both groups′ average scores had increased significantly, there was significantly greater improvement in the treatment group. ②There was also no significant difference in average β value between the two groups before the experiment, but afterward the average βs of channels 27 and 13 in the intervention group were significantly higher than in the control group. Moreover, in patients with lesion in the left brain, the β-values of CH27 and CH13 were also significantly higher than the control group ( P<0.05). ③The FMA-UE scores of the intervention group were moderately correlated with the CH27 and CH13 β values, but those of the control group were only weakly correlated with the β values of CH27. Conclusion:Transcranial magnetic stimulation activates a lesioned left brain region, improving upper limb motor function. The improvement is correlated with the activation of the left prefrontal cortex and the left primary somatosensory cortex.

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is an idiopathic chronic, progressive interstitial lung disease with a diagnosed median survival of 3-5 years. IPF is associated with an increased risk of lung cancer. Therefore, exploring the shared pathogenic genes and molecular pathways between IPF and lung adenocarcinoma (LUAD) holds significant importance for the development of novel therapeutic approaches and personalized precision treatment strategies for IPF combined with lung cancer. METHODS: Bioinformatics analysis was conducted using publicly available gene expression datasets of IPF and LUAD from the Gene Expression Omnibus (GEO) database. Weighted gene co-expression network analysis was employed to identify common genes involved in the progression of both diseases, followed by functional enrichment analysis. Subsequently, additional datasets were used to pinpoint the core shared genes between the two diseases. The relationship between core shared genes and prognosis, as well as their expression patterns, clinical relevance, genetic characteristics, and immune-related functions in LUAD, were analyzed using The Cancer Genome Atlas (TCGA) database and single-cell RNA sequencing datasets. Finally, potential therapeutic drugs related to the identified genes were screened through drug databases. RESULTS: A total of 529 shared genes between IPF and LUAD were identified. Among them, SULF1 emerged as a core shared gene associated with poor prognosis. It exhibited significantly elevated expression levels in LUAD tissues, concomitant with high mutation rates, genomic heterogeneity, and an immunosuppressive microenvironment. Subsequent single-cell RNA-seq analysis revealed that the high expression of SULF1 primarily originated from tumor-associated fibroblasts. This study further demonstrated an association between SULF1 expression and tumor drug sensitivity, and it identified potential small-molecule drugs targeting SULF1 highly expressed fibroblasts. CONCLUSIONS This study identified a set of shared molecular pathways and core genes between IPF and LUAD. Notably, SULF1 may serve as a potential immune-related biomarker and therapeutic target for both diseases.
