Objective To discuss the treatment effect of doctor-nurse cooperation in multi-plane operation of obstructive sleep apnea hypopnea syndrome.Methods 73 patients with multi-planar surgery due to OSAHS were divided into the observation group (38 cases) and the control group(35 cases) in our department from January 2008 to December 2012.Health care was strengthened throughout the course of treatment in the observation group and traditional treatment and care were adopted in the control group.Short-term and long-term efficacy,intraoperative and postoperative complications were compared between two groups.Results The operation of short-term effective rate was 100％,and significant differences were found in the long-term efficacy between the two groups.There were significant differences in nasal bleeding during surgery,one-time intubation success rate and the significances were found in postoperative pain,extubation time,lung infection and soft palate regurgitation between two groups.Conclusions The implementation of the multi-plane surgery for patients with OSAHS can effectively improve the short-term efficacy of the patients throughout the course of treatment.Strengthening doctor-nurse cooperation effectively improve the patients' long-term efficacy,reducing the patients' intraoperative and postoperative complications.

ObjectiveTo investigate the expression and relationship between phosphatase and tensin homology deleted on chromosome ten(PTEN) and vascular endothelial growth factor(VEGF) in bladder transitional cell carcinoma(BTCC) and their clinical significance.MethodsExpression of PTEN and VEGF were detected in 60 specimens by immunohistochemistry test(SP method).ResultsThe positive rate of PTEN was 47%(28/60) in BTCC;VEGF was 68%(41/60).With the pathological grade and the clinical stage of tumors being higher,the lower expression level of PTEN showed(P<0.05);while the expression of VEGF increased with no statistical significance(P>0.05),but having a significant difference between specimens with lymph nodes metastasis and without lymph nodes metastasis(P<0.05).The expression of PTEN was negatively correlated with that of VEGF(r=-0.439,P<0.01).ConclusionThe expression of PTEN and VEGF in BTCC plays an important role during the progress of carcinoma and is helpful to evaluate the prognosis of patients.

Objective To investigate the clinical effect of ultrasound-guided sclerosing therapy with injection of lauromacrogol for the treatment of pelvic encapsulated hydrops. Methods A total of 40 patients with pelvic encapsulated hydrops were enrolled in this study. Under ultrasonographic guidance , puncture aspiration of pelvic encapsulated hydrops was carried out in all patients , which was followed by lauromacrogol injection of appropriate dose, and the drainage catheter was kept in the hydrops cavity. The clinical results were evaluated at one, 2 and 3 months after the treatment. Results The success rate of puncturing was 100%. Six months after the treatment, the complete cure was obtained in 86.4%of patients, and the effective rate was 100%. Conclusion For the treatment of pelvic encapsulated hydrops , ultrasound-guided sclerosing therapy with injection of lauromacrogol is effective and safe with instant result and lower recurrence rate. Therefore, this technique should be recommended in clinical practice.

Objective To investigate the damages on pancreas after different fractionated irradiation in rats.Methods Eighy healthy adult Wistar rats were randomly divided into four groups with 20 rats in each group as conventional fractionated irradiation group with 2 Gy per fraction to a dose of 12 Gy,hypofractionated radiation group with one fraction of 12 Gy,middle-dose fractionated radiation group with 6 Gy per fraction to a dose of 12 Gy in the interval of 4 days and control group without radiation.Changes in weight,fasting blood glucose and amylase were measured and morphological changes were observed in different periods.Results In the experimental groups,the reduction was observed in fasting glucose at 4 d,reached a minimum of (3.1 ±0.1 ) mmol/L,(LSD-t =20.06 -28.74,P ＜0.001 ) and the increase of amylase was found after 4th and 7th day,reached a maximum of (84.5 ±6.4) U/L(Dunnett's-t=23.10 -46.10,P ＜ 0.001 ),both more obvious in hypofractionated radiation group than those of conventional fractionated radiation group and middle-dose fractionated radiation group ( LSD-t =8.72-9.71,Dunnett's-t =7.11,P ＜ 0.05 ),however the levels in conventional fractionated radiation group was nearly to middle-dose fractionated radiation group (P ＞ 0.05 ) and became normal at 14 d.Under light microscope,the necrosis of acinarcells was observed in hypofractionated radiation group at 4th d,interstitial fibrogenesis were found at 14 d,the fibrogenesis were found in pancreatic island at 21 d,and the hyperplasia of acinarcells was observed at 42 d.The same changes were found in conventional fractionated radiation group and middle-dose fractionated radiation group,which were gently and lately than those of hypofractionated radiation group.Conclusions Radiation injury is not more serious after middle-dose fractionated radiotherapy than that after conventional fractionated irradiation,when the proper fractional dose and intervals are chosen.

Synovial sarcoma is a rare tumour found in soft tissue; it is a mesenchymal spindle cell tumour that is not related to the synovial membrane. This tumour has a low incidence, and the most frequent place of occurrence is the lower extremities in young adults. Synovial sarcoma of the head and neck accounts for 3%-5% of sarcomas in this anatomical region. The tumor in the nasal cavity is less than 1%. The treatment of choice for synovial sarcoma of the head and neck is complete surgical excision of the tumour mass followed by adjuvant radiotherapy.

Objective To compare the diagnostic value of 64-slice helical CT cholangiography and MR cholangiopancreatography (MRCP) for pancreaticobiliary obstructive diseases. Methods Thirty-six patients with pathologically proved pancreaticobiliary obstruction or endoscopic retrograde cholangiopancreatography (ERCP) were examined with MRCP and routine enhanced CT scanning. CT row data of portal venous phase were reconstructed with 0.625 mm thickness and intervals. Then multiplanar reformation (MPR) of intra- and extrahepatic biliary duct, gallbladder and pancreas was generated, and curved planar reformation (CPR) was performed when necessary. The accuracy of MPR (and CPR) and MRCP in evaluating the site and nature of obstruction was compared. Results The accuracy of MPR and MRCP was 97.22% and 94.44% in evaluating the site of obstruction, respectively. In evaluating the nature of obstruction, the accuracy of MPR and MPCP was 83.33% and 80.56%, respectively, and the accuracy of MPR increased to 88.89% in combination with CPR in some patients. There was no statistical difference between the accuracy of MPR and MRCP in evaluating the site and nature of obstruction, while their diagnostic consistency was medium (Kappa=0.471). Conclusion Both MSCT cholangiography and MRCP have high diagnostic value in pancreaticobiliary obstruction, while the former gets some advantages in images review for clinicians.

Objective To retrospectively analyse the efficacy and the influencing factors of plasma exchange(PE)in patients with chronic severe hepatitis.Methods Sixty patients of chronic severe hepatitis were included.Results The effective rate was 61.7%.The efficacy of PE was closely related to age,clinical stage,pre-treatment serum bilirubin values,prothrombin activity and incidence of complications(P0.05).Conclusion PE can significantly improve the survival of patients with chronic severe hepatitis.Especially for the patients under 60 years old,those with low serum TBIL level and high PTA,and those in the early clinical stage,PE treatment would achieve a better efficacy.But the improvement of prognosis of severe hepatitis still depends on the early specific treatment and active prevention of complications.

Objective To evaluate the clinical effect of Liyanjiedu decoction for the prophylaxis and treatment of acute radiotherapy-induced oral mucositis of nasopharyngeal carcinoma(NPC)and the influence to the effect of the radiotherapy to NPC.Methods A total of 96 patients with NPC were randomly divided into treatment group and control group,48 cases for each group.The two groups were given radical radiotherapy.The treatment group was given Liyanjiedu decoction for buccal.The control group were given western medicine for mouthwash.The course of two groups was all from the beginning of radiotherapy to the end of it.Results The occurring time of radiotherapy-induced mucositis in treatment group and control group were(21?4.2)d and(16?3.6)d,and radiotherapeutic dose were(40.252?11.758)Gy and(29.625? 11.632)Gy,with significant difference between the tow groups(P

AIM To study the central role of genistein (GST) in regulating cardiovascular function of nervous center by examining the effects of GST on the electrical activity of rat paraventricular nucleus neurons in slice preparation and to elucidate the mechanism involved. METHODS Using extracellular single-unit discharge recording technique to examine discharges of neurons in paraventricular nucleus of hypothalamic slices at the resting potential level. RESULTS ①In response to the application of GST 10, 50 and 100 μmol·L-1, respectively, in the perfusate for 2 min, the spontaneous discharge rates (SDR) of neurons in 25/26 hypothalamic slices were significantly decreased in a concentration-dependent manner. ②Pretreatment with L-glutamate 0.2 mmol·L-1 led to a marked increase in the SDR of slices in an epileptiform pattern. GST 50 μmol·L-1 significantly attenuated the increased SDR in all 7 slices. ③In 8/8 slices, the G protein-coupled inwardly rectifying K+ channels (GIRKs) antagonist, tetraethylammonium 1 mmol·L-1 completely blocked the inhibitory effect of GST 50 μmol·L-1. ④Pretreatment with nitric oxide synthase inhibitor Nω-nitro-L-arginine methyl ester 50 μmol·L-1 increased SDR in all 7 slices, but did not affect the inhibitory effect of GST 50 μmol·L-1. CONCLUSION GST can inhibit the electrical activity of paraventricular neurons, and play a protective role on the central neurons. The inhibitory effect of GST may be related to the activation of GIRKs which induce K+ outward current and then engender the cell membrane hyperpolarization, but be not due to the NO release.
