Objective This research is to observe the treatment effects of hip bath and oxygen blowing on severe neonatal diaper rash.Methods 289 neonates with severe diaper rash were randomly divided into three groups.91 cases in the flat tube group,102 cases in the round tube group and 96 cases in the control group.Three groups of neonates were cleaned on the hips and perineuma after poops and then dried with wet tissues and Mupirocin Ointment.The control group was treated with the above-mentioned method.The oxygen blowing groups were treated with hip bath of 1:5000 chameleon solution twice a day.Blowing the hips with oxygen five minutes every time after hip bath.The method of blowing oxygen was that oxygen humidifying containers as normal oxygen aspiration facilities was not filled with water,whose oxygen flowing volume standed at 10 L/min and whose tube blew at the afflicted parts until being dry.The oxygen blower held the oxygen exit and blowed at the afflicted parts in the round tube group and the oxygen blower flattened the oxygen exit and blew at the afflicted parts in the fiat tube group.The treatment effects will be compared among the three groups four days later.Results The cure period of the round tube group was obviously shorter than that of the control group,and the cure period of the fiat tube group was remarkably shorter than that of the round tube group.The total effective rate in the round tube group was obviously higher than that of the control group and the total effective rate in the fiat tube group was obviously higher than that in the round tube group.The difference had a statistical significance.Conclusions The treatment effects for the severe neonatal diaper rash with hip bath and oxygen blowing are remarkable and the oxygen blowing effects with fiat tubes are better than those with round tubes.

Objective To assess the CT image quality of the pure ground glass nodule(pGGN)in chest phantom by using different field of view(FOV)and matrix.Methods CT(Philips Brilliance 128 spiral CT)scans were performed on chest phantom containing 9 artificial pGGNs(diameter≥5 mm)in 3 different FOV (50 mm,150 mm,300 mm ),and were reconstructed in 2 different matrix(512×512, 1 024×1 024),standard kernel.Recorded the CT values and standard deviations (SD)of the nodules and surrounding regions in different FOV and matrix,and calculated the mean standard deviation(MSD),contrast noise ratio (CNR)and signal noise ratio (SNR),then compared the difference among them.Two radiologists assessed the image quality of the pGGNs in blind method respectively,then evaluated the coherence between them using Kappa testing.Results The coherence of 2 observers was substantial or almost perfect.No significant differences were found on MSD,CNR and SNR in different FOV (P value>0.05)when matrix was kept,whereas the visibility of the nodules improved with the FOV changing smaller.And there were significant differences all on MSD,CNR and SNR by using different matrix when FOV was kept.The MSD increased and the CNR,SNR decreased in high-resolution group.The visibility of the pGGNs was not improved obviously in high-resolution group.Conclusion The image quality of the pGGN(diameter≥5 mm)won’t be changed by using smaller FOV when matrix is kept ,but the visibility will be improved with the FOV changing smaller.When FOV is kept,the MSD increased and the CNR,SNR reduced in high-resolution group,but the visibility will not be improved obviously compare to the standard resolution group.

OBJECTIVE: To investigate the preservation of the structure and function of the trachea and larynx, the management of laryngotracheal defect when trachea and larynx was involved. METHOD: To review the management and clinical results of 13 cases of thyroid papillary carcinoma with larynx and trachea involvement, the preservation of laryngotracheal structure and relative defect reconstruction of our department from 2007-2014. Those patients being performed total laryngectomy was excluded. 3 males and 10 females, aged from 46 to 67 years old with median age of 53 were included. Among them 8 cases were recurrent. The extent of the tumor foci was estimated with the help of computed tomography and laryngofiberoscope before surgery. Selective neck dissection, total thyroidectomy and related laryngotracheal resection was performed for the first time operation patient, while selective neck dissection, recurrent foci and related larynx and trachea resection was performed for those recurrent patients. Three kinds of modalities were applied to manage the laryngotracheal defect including to reconstruct with pedicled sternocleidomastoid clavicular periosteocutaneous flap, pedicled trapizius muscular flap and to preserve the remaining larynx and trachea and perform a stoma of larynx and trachea which repaired by a second-stage procedure. The patients were followed-up from half an year to 3 years. RESULT: Ten patients out of 13 decannulated while another 3 cases, 2 of which were performed local flap to reduce the stoma, wore tracheal tubes all time. CONCLUSION Either flap transfer or laryngotracheal stoma before second stage repair might preserve partial laryngotacheal anatomy and function in selected cases thus improve the life quality of the patients.

OBJECTIVE: To investigate the feasibility of utilizing pedicled sternocleidomastoid clavicular periosteocutaneous flap to reconstruct the laryngotracheal defect after tumor resection. METHOD: To review 6 cases of laryngotracheal defect resulting from resction of thyroid papillary carcinoma(4/6) or subglottic laryngeal carcinoma (2/6) (T1~2N1~2M0 , UICC,2002), laryngotracheal stenting was also employed in all cases. Half a year after surgery, the stoma was sutured if no local recurrence took place and safety was proved after tracheal tube had been obstructed for days. The follow-up time lasted from half a year to 3 years. RESULT: Four cases (4/6) were extubated successfully without event, one case could intermittently plug the tracheal tube. One patient couldn't breath with tracheal tube plugging. CONCLUSION To reconstruct the laryngotracheal defect with pedicled sternocleidomastoid clavicular.periosteocutaneous flap after tumor resection is feasible in selected cases and could get satisfactory clinical results either in respiration or phonation.

Gene knockout by ZFNs (zinc-finger nucleases) is efficient and specific, and successfully applied in more than 10 organisms. Currently, it is unclear whether this technology can be used for knocking-out enhanced green fluorescent protein (EGFP) gene in transgenic goats. Here we constructed and used ZFN-coding plasmids to produce genetic knockouts in the cells of cloned fetus produced from donor cells by microinjection of EGFP gene. Following introduced plasmids into caprine primary cultured fetus fibroblasts by electroporation, targeting of a transgene resulted in sequence mutation. Using the flow cytometric analysis, we confirmed the disappearance of EGFP expression in treated cells. Sequence from PCR products corresponding to targeted site showed that insertion of a G into the exon of EGFP resulted in frame shift mutation. These results suggest that ZFN-mediated gene targeting can apply to caprine fetus fibroblasts, which may open a unique avenue toward the creation of gene knockout goats combining with somatic cell nuclear transfer.

Objective To evaluate therapeutic effect of endoscopy on duodenal papilla tumor. Methods Clinical data of patients who underwent the endoscopic duodenal papilla tumor resection in Zhongshan Hospital were retrospectively studied from April 2007 to May 2014. Results A total of 21 patients underwent 28 procedures. Postoperative biliary stent were retained in 6 cases (6/28) , with no perforation or postoperative pancreatitis. Delayed bleeding occurred in 7 cases (7/28) and controlled by endoscopic hemostasis, and no death occurred. Mean follow-up was 31. 5 months. There were 6 recurrent cases, and mean recurrence time was 14. 1 months. All these recurrent cases are treated by endoscopy treatments or surgery. Conclusion Endoscopic treatment of duodenal papilla tumor is safe, effective and minimally invasive, but the occurrence of delayed bleeding is worth concern.

OBJECTIVE: To investigate cervical esophageal reconstruction by means of laryngo-tracheal flap after resection of hypopharyngeal carcinoma with cervical esophageal involvement. METHOD: Eleven cases of hypopharyngeal carcinoma with cervical esophageal involvement. Unilateral piriform sinus and cervical esophagus were involved in 8 cases (8/11) while bilateral piriform sinus, posterior pharyngeal wall and cervical esophagus were involved in 3 cases. After resection of laryngeal, pharyngeal and esophageal tumors and bilateral neck dissection, direct anastomosis of larynx and trachea with esophagus of cervico-thoracic segment was performed if circular structure of larynx and trachea could be preserved (3/11), pectoralis major myocutaneous flap was employed if only part of pharynx and larynx could be preserved (8/11). Postoperative radiochemotherapy was adopted and follow-up lasted for 1-5 years. RESULT: All cases healed without event except for one case of pharyngeal fistula and one case of chylous fistula which also healed after about 2 weeks dressing change. All patients got normal diet without anastomotic stricture. There was no recurrence in 6 patients at the 3 years follow-up, 4 patients had metastases in the neck and 1 patient had thoracic esophageal carcinoma with hepatic metastasis arid gave up further treatment. The overall 3-year survival rate was 54.5%. CONCLUSION Using laryngo-tracheal flap to reconstruct cervical esophagus after resection of hypopharyngeal carcinoma with cervical esophageal involvement is a recommendable method that is simple in processing, reliable in effect and less in postoperative complications.

Objective To investigate the prevalence of hyperuricemia and gout in a community population of Huangpu District in Shanghai.Methods In the target community, 2037 dwellers were interviewed with relevan questionnares from house to house. According to even house number 1017 blood samples were taken for serum uric acid (SUA) levels measured with the uricase-peroxidase enzymatic method.Results The prevalence of hyperuricemia was 14.2% in men (SUA>70 mg/L, 62 cases), 7.1% in women (SUA>60 mg/L, 41 cases), 10.1% in both sexes. Seven gout patients were all men. The prevalence of gout in 2037 dwellers in Huangpu District was 0.77% in men and 0.34% in both sexes.Conclusions The mean SUA level in each age group in this survey was much higher than that of a previous study 1 carried out in Shanghai, Beijing and Guangzhou in 1980 (P<0.05). And the prevalence of hyperuricemia was increased rapidly (in men: from 1.4% in the survey of 1980 to 14.2% in our survey; in women: from 1.3% in the survey of 1980 to 7.1% in our survey). Compared with Idonesia data in 1992,2 the prevalence of hyperuricemia and gout in our survey was lower than that in Indonesia (P<0.05), which suggests that racial and genetic predispositions are key causative factors.
