Objective To explore the effect of peer-education on self-efficacy of hemodialysis(HD) patients. Methods Totally 90 HD patients were divided into two groups equally. The intervention group received peer-education for 3 months and the control group received routine nursing. The two groups were compared in terms of score on self-efficacy. Results There was no statistically significant difference in the score on self-efficacy and every item between the two groups before intervention (P>0.05). The score on self-efficacy and the items ofcontrol of depressive mood, the confidence in taking self-care measures, the confidence in doing other thingswere statistically significantly different between the two groups after intervention (P<0.05). Conclusion Peer-education can improve HD patient′s self-efficacy.

OBJECTIVE To explore the method of replacing nasal packing after septoplasty. METHODS A total of 158 patients who had undergone septoplasty were included in this study. The patients were randomly allocated into two groups: packing group and suturing group. Postoperative signs and symptoms were compared between the two groups by visual analogue scale(VAS). RESULTS The patients of packing group experienced significantly more postoperative nasal pain, headache, epiphora, tinnitus/ear fullness, sleep disturbance after surgery(all P<0.05). There were no statistically significant differences between two groups in terms of nasal congestion, hemorrhage, septal hematoma, nasal septum perforation and local infection(all P>0.05). CONCLUSION Nasal septum continuous suture is a simple technique to decrease patients' suffering. It does not increase the complications and is a feasible method to replace nasal packing after septoplasty.

OBJECTIVE: To discuss the application of frontal sinus optical probe in endoscopic frontal sinus surgery. METHOD: The clinical data of 58 adult patients (86 sides) suffering from chronic frontal sinusitis were analyzed retrospectively. The patients received endoscopic frontal sinus surgery with frontal sinus optical probe because of difficulty in confirming ostia under endoscope. All cases were followed up post operation to evaluate the efficacy. RESULT: The ostia of frontal sinus were successfully opened with this method in all cases, and no serious intracranial or orbital complication occurred. After 6 to 18 months follow-up postoperatively, the symptoms vanished in 51 cases and improved in 7 cases and none of all recurred. The endoscopic examinations showed well opening of frontal sinus ostia. CONCLUSION Localization of frontal ostium with frontal sinus optical probe is a simple, convenient, safe and effective accessorial method for revision endoscopic frontal sinus surgery.

Objective To report the treatment outcome of nonunion of tibial fractures with local muscle flap transfer and injection of autogenous bone marrow. Methods 15 patients who had suffered from nonunion of tibial fracture 10 to 42 (mean 22) months after the initial injury underwent open reduction, internal fixation with locking intramedullary nail, wound coverage with locally transferred muscle flap and injection of autogenous bone marrow into the fracture site 12 to 15 days after operation. Results The follow-ups revealed bone union in all the cases of this series with a mean healing time of 22 (3 to 11) months. Except for limited necrosis of the skin edge in 2 cases which healed after dressing changes, the wounds healed primarily in all the cases without infection and implant failure. Conclusion Besides stable internal fixation and bone graft, coverage of fracture site with locally transferred muscle flap and injection of autogenous bone marrow can be used to treat nonunion of tibial fractures with satisfactory results.

Objective To explore the efficiency of endoscopic septoplasty with submucous resection for the treatment of 220 patients with deviated nasal septum and report our experience in this field. Methods From May 2006 to May 2010, 220 patients with deviated nasal septum were treated by endoscopic septoplasty with submucous resection to decompress the stress points, resect the deviated parts and implant the reshaped bone of nasal septum, while retaining the normal structure of nasal septum with minimally invasive technique. Results Satisfactory effects were achieved in all the 220 patients, showing centered septal structure and disappeared symptoms such as nasal obstruction, headache and nasal hemorrhage, but no complications including perforation of nasal septum, depressed nasal bridge and septal chalasia and flaring. Conclusion Rhino-endoscopic septoplasty with submucous resection can substantially retain the original structure of nasal septum and thus is proven to be a desirable operation with multiple advantages including minimal invasiveness, quicker healing and fewer complications.

A spectrophotometric method for the determination of calcium in milk, hair and urine was developed using metal complezing dye orthocresolphth-alein complexone(OCPC).The organic matter in the tested sample was destroyed by digestion. An aliquot of the digested solution was mixed with color developing reagent, alkaline OCPC, cantaining 8-quinolinol to suppress interference such as magnesium, and the absorbance was measured at 570 nm.The coefficients of variation were 0.87, 3.6 and 1.2% for milk, hair and urine samples; and the analytical recoveries of calcium from milk, hair and urine averaged 100.4, 101.0 and 98.5% respectively. The calcium content of milk and hair determined by this method was closely correlated with that of the ICP-AES method (r =0.994, p

Objective To discuss the diagnostic value of serum sialic acid for glioma.Methods A retrospective study was conducted.The levels of sialic acid in serum samples of 95 glioma patients, 175 patients with brain benign tumor and 400 normal persons from October 2014 to March 2015 were detected by automatic biochemistry analyzer using enzymic method.The SNK-q test and analysis of variance were used to compare the difference of the groups.By making receiver operating characteristic ( ROC) curve, the cut-off value, sensitivity, specificity, positive predictive value and negative predictive value were calculated to assess the diagnostic value of serum salivary acid.Then the cut-off value was validated by using the serums of 30 glioma patients and 30 normal persons who were out-patients and healthy controls.Results The levels of serum sialic acid in patients with gliomas, patients with brain benign tumor and healthy individuals were (0.66 ±0.14 ) g/L, (0.61 ±0.09 )g/L, (0.54 ±0.07 )g/L.The serum salivary acid of glioma patients were higher than brain benign tumor patients (q=6.74,P<0.05) and normal persons (q=16.42,P<0.05), and there was no significant difference (F=1.67,P>0.05) among the glioma patients of different grades (8 of gradeⅠ,32 of gradeⅡ,24 of grade Ⅲ,31 of grade Ⅳ).There was no significant difference between the low grade patients (gradeⅠandⅡ) and the high grade patients (gradeⅢandⅣ) (t=0.55, P>0.05), but the level of serum sialic acid of high grade group had an increasing trend than the low grade group.The area under the ROC curves was 0.79.The cut-off value of serum salivary acid for diagnosing glioma was 0.61 g/L.The sensitivity was 67.74%, and the specificity was 80.60%.The positive predictive value was 44.68%, and the negative predictive value was 90.76%.Then the cut-off value was used as a diagnostic criteria, and the detected results of 30 glioma patients and 30 normal persons showed that the sensitivity was 63.30% and the specificity was 83.30%.Conclusions The serum sialic acid has good specificity and negative predictive value for diagnosing glioma.It may be a valuable diagnostic marker.

ObjectiveTo evaluate the significance of the detection of serum C-reactive protein (CRP) in elderly patients with diabetes mellitus and cerebral infarction.MethodsSeventy-two patients with diabetes mellitus and cerebral infarction (diabetic cerebral infarction group),66 patients with cerebral infarction and without diabetes mellitus (non-diabetic cerebral infarction group) and 60 healthy persons (control group) from October 2008 to January 2011 were selected.The level of serum CRP was detceted.ResultsThe level of CRP was ( 3.81 ± 2.23 ) mg/L in diabetic cerebral infarction group,( 2.48 ± 2.24 ) mg/L in non-diabetic cerebral infarction group and (0.68±0.16) mg/L in control group.The levels of CRP in diabetic cerebral infarction group and non-diabetic cerebral infarction group were significantly higher than that in control group (P ＜ 0.05).The level of CRP in diabetic cerebral infarction group was obviously higher than that in non-diabetic cerebral infarction group(P ＜0.05).CRP abnormal rate was 70.8％(51/72) in diabetic cerebral infarction group and 43.9％ (29/66) in non-diabetic cerebral infarction group,which had statistical significance (P ＜ 0.05).ConcluslonCRP has important predictive value to the occurrence and development of diabetic cerebral infarction.

OBJECTIVE To study the electrophysiological character of the Auditory Brainstem Response to Speech Sounds (s-ABR) in healthy adults. METHODS We assessed the auditory brainstem response to a synthesized stop-consonant speech syllable /da/ in 40 native-Chinese speech adults (20 female). Timing components of the response were compared between males and females to determine the relationship between inducing rate ,latency of waves and sex and age of participants. RESULTS The latency of wave V and A was shorter in females was that of males (Vt(38)=-3.601, P =0.001, At(38)=-2.829, P=0.007).The other peaks latency except V、A can see difference between gender but do not have statistics differences (P>0.05); The latency has no statistical difference in different age (P>0.05); The amplitude has no statistical difference in different gender and age (P>0.05). CONCLUSION The waves of s-ABR has good stability for studying mechanism of auditory speech processing tools.
