This review focus on the progress of the treatment of obstructive sleep apnea-hypopnea syndrome by using positive airway pressure and upper airway multilevel surgeries. OSAHS is a disease caused by multiple etiologies. We should consider upper airway anatomical abnormalities and the severity of OSAHS before reasonable treatment plans were formulated. "PAP-surgery-PAP" is the classic procedure for treating moderate OSAHS and severe OSAHS. Preoperative use of PAP could reduce the hypoxic condition of patients and decrease surgical risk. Surgery can effectively reduce the optimal PAP pressure value, and increase the tolerance of patient. Postoperative use of PAP can improve surgical efficacy, shorten patient recovery time. However, the influence of different surgical methods on optimal PAP pressure value is lacking in large samples. More related studies need to be per formed in the future.

Objective To explore the association between C reactive protein (CRP)with prostatic cancer (PCa)and benign prostatic hyperplasia (BPH).Methods Retrospective analysis the 110 patients of the First Affiliated Hospital of Zhejiang University In January 2010 to August 2012 whose TPSA>4 ng/ml,postoperative pathology confirmed the diagnosis of 54 cases of prostate cancer,5 6 cases of benign prostatic hyperplasia.Detected serum CRP levels by using transmission turbidim-etry and TPSA levels by using chemiluminescence immunoassay of 54 PCa and 56 BPH patients.According to the Gleason score,PCa patients were divided into high-risk and low-risk PCa two groups,the differences among high-risk PCa,low-risk PCa and BPH groups were analyzed by nonparametric statistics analysis.Results The CRP level of high-risk PCa was 4.20~2.12 mg/L,the CRP level of low-risk PCa was 1.90~0.91 mg/L and the CRP levels in BNP patients was 1.49±0.87 mg/L,the high-risk and low-risk PCa serum CRP level obviously higher than that of patients with BPH,the differences were statistically significant (P<0.05).Conclusion Serum CRP levels of PCa patients were increased significantly,espe-cially in high-risk PCa patients.

Objective:To investigate the effects of clinically achievable dose of lovastatin on prostate cancer PC3 cells.Methods:PC3 prostate cancer cells were treated with dimethyl sulfoxide(DMSO),or lovastain only,or lovastatin with mevalonic acid for 24,48 and 72 hours respectively.MTT assay was used to detect the cell viability.By means of [3H] thymidine incorporation tests,the effects of lovastatin on cell proliferation were analyzed.Western blot was used to detect activated casepase3,caspase7,and cleaved PARP(cPARP),the important molecules on the apoptosis pathway.Results:Cell proliferation of PC3 was significantly inhibited by 39.29%[(63.69%?3.69%) vs(102.98%?6.84%),P=0.000] after 48 h treatment with lovastatin at its clinically achievable dose of 2 ?mol/L.After 72 hours the cell proliferation was inhibited by 44.24% [(52.79%?9.88%) vs(97.03%?0.87%),P=0.048].The cell number was also markedly decreased(4.86?105 ? 0.10?105) vs(9.66?105?0.10?105),P=0.000] after 72 h treatment at this low concentration of 2 ?mol/L.The viability of PC3 cells was significantly decreased 50.12%(56.52%?6.40%) vs(106.64%?5.27%),P=0.000] and 60.05%(41.99%?11.64%) vs(102.94%?8.49%),P=0.000] after 48 h and 72 h treatment,respectively.In addition,2 ?mol/L lovastatin induced activation of casepase7 and led the death substrate PARP to cleavage.Conclusion:Clinically achievable dose of lovastatin inhibits prostate cancer PC3 cell proliferation and induces PC3 cell apoptosis.

AlM: To observe the effects of the coelomic cavity injection of triamcinolone acetonide ( TA) combined with laser photocoagulation on patients with retinal vein occlusion.
METHODS:Fifty-six patients of retinal obstruction with macular edema were accepted from January 2010 to December 2012 in our hospital. All patients received iodized lecithin and Xueshuantong. And, patients with central retinal vein occlusion ( CRVO ) , hemi- central retinal vein occlusion ( hemi-CRVO ) and branch retinal vein occlusion ( BRVO ) treated by TA combined with laser photocoagulation, respectively. Follow-up period was of at least 6mo
RESULTS: After the treatment of 1, 3 and 6mo, the central foveal thickness was reduced significantly ( P<0. 05). After followed up 6-12mo, the total effective rate of CRVO, Hemi-CRVO and BRVO patients was 83% ~95% and all the patients had no significant adverse reactions.
CONCLUSlON:Basing on the traditional treatment, TA combined with laser photocoagulation is more effective in the treatment of retinal vein occlusion and is worthy of clinical usage.

? AlM: To evaluate the efficacy of the method of vitrectomy combined with posterior sclera reinforcement for retinal detachment due to macular hole in high myopia.
?METHODS:From January 2012 to December 2013, in 45 eyes of 45 high myopic patients with retinal detachment due to macular hole, 28 eyes were in group A of vitrectomy with posterior sclera reinforcement and 17 eyes were in group B of vitrectomy. Preoperative examinations included visual acuity, intraocular pressure, indirect ophthalmoscopy and OCT were performed. ln follow - up 6 to 12mo, postoperative examinations of visual acuity, OCT were performed and effects of retinal reattachment and macular hole closure were compared between the two groups.
?RESULTS: ( 1 ) Postoperative examinations: visual acuity was 1. 19±0. 39 in group A and 1. 51±0. 34 in group B. The differences were statistically significant(P<0. 05). (2) The retinal reattachment rate was 100% in group A and 88. 24% in group B. There was no statistical significance between them(P>0. 05). (3) The macular hole closure rate was 82% in group A and 53% in group B. The differences were statistically significant(P<0. 05).
? CONCLUSlON: The treatment of vitrectomy with posterior sclera reinforcement is safe and feasible, which could improve visual acuity and increase the rate of macular hole closure in treating retinal detachment due to macular hole in high myopia.

To increase the biotransfomation efficiency from the orotic acid to the uridine 5'-monophosphate(UMP),URA5 gene encoding orotate phosphoribosytransferase was amplified from Saccharomyces cerevisiae BY4742 by PCR,then it was inserted into the expression vector pYX212(contained orotidine monophosphate decarboxylase gene URA3)and the pYX212-URA5 was transformed into Saccharomyces cerevisiae BJX12 by electroporation.The recombinant strain was elementarily used to convert orotic acid to UMP.The results showed that pYX212-URA5/BJX12 could accumulate 7mmol/L UMP from 32mmol/L orotic acid in 26h,significantly higher than both control groups pYX212/BJX12(2.7mmol/L) and BJX12(2.4 mmol/L).

Objective To explore the influence of candesartan (an angiotensin II receptor 1 antagonist,AT1R) in radioresistance of human nasopharyngeal carcinoma CNE1 cells.Methods Cell growth of CNE1 with or without candesartan treatment was measured in vitro by MTT method;radiosensitivity of CNE1 with or without candesartan treatment was tested under normoxic or hypoxic conditions by clone formation assay.The expression of hypoxia-induced factor 1α(HIF-1α)in CNE1 cells was analysed by western blotting.Results Candesartan did not significantly inhibit the growth of CNE 1 cells in both normoxic and hypoxic conditions.Candesartan also did not influence the radiosensitivity of CNE1 cells in normoxic condition;however,it significantly increased the radiosensitivity of CNE1 cells in hypoxic condition.The expression of hypoxia-induced factor 1 α (HIF-1 α)in hypoxic CNE1 cells was significantly inhibited by candesartan treatment.Conclusion Candesartan does not significantly influence the proliferation of CNE1 cells in both normoxic and bypoxic conditions but significantly enhances the radiosensitivity of hypoxic CNE1 cells,in which the mechanisn may be involved in its inhibiting HIF1α expression in hypoxic CNE1 cells.

Objective To know the correlation of anxiety and pains of out-patients who had accept-ed operation and the effect of nursing intervention. Methods Divided 173 out-patients with operation in-to the intervention group(83 cases) and the control group(90 cases) randomly. Routine nursing cares was used in the control group, preoperative health education was used in the intervention group in addition. Us-ing the Me-Gill and SF-MPQ to evaluate pains between the 2 groups. Using the S-AI and the T-AI to evaluate the emotional condition between the 2 groups. Results The indexes which can indicated the pains and emotional condition in the intervention group after the health education were significant better than those of in the control group and themselves before the nursing intervention. Conclusions Preoperative pains and emotional condition should be evaluated among out-patients, and then carry out certain counter nursing measures to release patients' pain and negative emotion.
