Objective:To study the effect of uvulopalatopharyngoplasty(UPPP) by using radio frequency plasma on obstructive sleep apnea-hypopnea syndrome(OSAHS) with Velopharyngeal obstruction.Method:Eighty-one cases that were diagnosed as OSAHS with Velopharyngeal obstruction were randomized into two groups, UPPP group and radio frequency plasma Velopharynoplasty group. Result:Six months after operation, the effects in both groups were similar.Conclusion:Radio frequency plasma Uvulopalatopharyngoplasty is safe, time saving, less hemorrhage with good effects.

OBJECTIVE To study the best timing of tonsillectomy for peritonsillar abscess (PTA).METHODS The clinical data of 326 cases with PTA were reviewed.Among them,167 cases (group 1) underwent tonsillectomy in the period of abscesses,the other 159 cases (group 2) underwent elective tonsillectomy.RESULTS In group 1,the mean unilateral bleeding was (10?2.3)ml during operation,postoperative bleeding rate was 3.0%, mean operation time was (10?1.2)min and mean hospitalization period was (8?1.1)d.While in group 2,the mean unilateral bleeding was (21?2.1)ml during operation,postoperative bleeding rate was 6.9%,mean operation time was (20?1.5)min and mean hospitalization period was (16?1.3)d.There were significant differences between the two groups in the bleeding amount,operation time,postoperative bleeding rate and hospitalization period (P0.05). CONCLUSION For patients with good general conditions and no contradiction for operation, tonsillectomy implemented 3-4 days after drainage of abscess shows obvious advantages than elective operation.

Objective: To investigate the pharmacodynamics of modified Xiaochaihutang granules (MXG) and its active ingredients group (AIG) on gastric ulcer in order to provide scientific basis for the clinical effect and lay foundation for the development of related hospital preparations.Methods: Gastric ulcer models induced by pyloric ligation,acetic acid and ethanol were applied to observe the curative effects of MXG and its AIG, and the effects of MXG and its AIG on gastric secretion, gastric acid content, pepsin activity, superoxide dismutase (SOD) and malondialdehyde(MDA) contents were also studied.Results: Compared to the model control group,MXG and AIG could significantly reduce the ulcer index(P<0.01), total acidity(P<0.01),and pepsin activity (P<0.05 or 0.01), increase the SOD activity (P<0.05)and inhibit the increase of lipid peroxide MDA.Conclusion: MXG and AIG show better control effects on acute and chronic gastric ulcer, and the effects are related to reducing the activity of pepsin, increasing the SOD activity, inhibiting the increase of lipid peroxide MDA and so on.

OBJECTIVE To investigate the clinical efficacy of microwave ablation in treating snoring and obstructive sleep apnea hypopnea syndrome(OSAHS). METHODS Eight patients with snores and 48 with OSAHS were included in the study. They all received micro-surgeries including plastic operations on the uvula and soft palate,tonsil ablation and tonsillectomy,inferior nasal concha and adenoid ablation,and de-volume of the tongue root. Symptoms six months before and after surgery were monitored by Polysomnography(PSG). RESULTS In 56 cases, the patients’ throats were widened. The mean values of the apnea hypopnea index(AHI), the lowest saturations (LSaO2) and the snoring index were significantly different before and after surgery(P

OBJECTIVE: To explore the clinical characters and treatment on solitary sphenoidal sinus disease thus improve the initial diagnosis accuracy and curative rate together with avoiding severe complications. METHOD: Forty-six cases were included in the study. The clinical manifestations, medical imaging characteristics and type of pathology and surgical treatment efficacy were analyzed retrospectively. RESULT: The main symptoms were headache and visual lesion. Medical image showed pace occupying lesion and partial destruction of bone. Pathological exams showed 8 cases with sphenoiditis, 19 cases with fungal infection, 10 cases with cysts and 9 cases with polyposis. All the patients underwent open sphenoidal surgery with nasal endoscope. After a follow-up of over 6 months, most of the patients' symptoms had been obviously relieved. And the entrance to sphenoid was patent with smooth sinus wall and no secretion in sinus cavity. CONCLUSION There is no specificity with solitary sphenoidal sinus disease. Pre-operation diagnosis rate can be improved with the help of nasal endoscope and CT or MRI. Nasal sinus surgery with nasal endoscope may be the first choice for treatment.

OBJECTIVETo assess the accuracy of quantitative fluorescence PCR(QF-PCR) for the detection of fetal chromosomal aneuploidies and its values for prenatal diagnosis.

METHODSQF-PCR and chromosomal karyotyping were used to analyze 6066 amniotic fluid samples derived from 6034 pregnant women.

RESULTSBoth QF-PCR and karyotyping analysis have detected 135 cases of fetal aneuploidies involving chromosomes 21, 18, 13, X, and Y. The QF-PCR assay was also successful in 67 cases for which amniotic fluid culture has failed. Furthermore, it has identified maternal cell contamination in 7 cases. By determining the consistency of short tandem repeat (STR) sites, the QF-PCR assay has identified 22 dizygotic twins among 32 twins with double chorions and double amniotic sacs. In 12 cases, it has signaled numerical chromosomal aberration by critical or partial abnormal values for the fluorescence peak area ratio, which were verified by karyotyping analysis as mosaicisms of chromosome aneuploidies.

CONCLUSIONThe QF-PCR can provide an useful supplement for chromosomal karyotyping and has an important role in rapid prenatal diagnosis.
