Objective To investigate the effect of N-acetyl-seryl-aspartyl-lysyl-proline (AcSDKP) on the synthesis of collagen and the expression of NF-κB p65 in lung of rats with silicosis fibrosis .Methods Rats were divided into 3 groups randomly :the control group(each rat was intratracheally instilled with 1 mL normal saline and killed after 8 weeks ,the silicotic model group(each rat was intratracheally instilled with 1 mL silica suspension and killed after 8 weeks ,the AcSDKP treated group(each rat was intra-tracheally instilled with 1 mL silica suspension and AcSDKP (800 μg · kg -1 · d-1 ) was administered into every rat ,then rats were killed after 8 weeks .Lung fibrosis in morphology and collagen content was observed by HE and vg staining and hydroxyproline as-say .The expression of NF-κB p65 was detected with the immunohistochemistry and Western blot .Results Compared with the con-trol group ,the quantity of silicon nodules ,collagen content and the expression of NF-κB p65were increased in the silicotic model group .Compared with the silicotic model group ,the quantity of silicon nodules ,collagen content and the expression of NF-κB p65 were decreased in the AcSDKP-treated group .Conclusion AcSDKP could inhibit the activity and expression of NF-κB p65 by strengthening the stability of I-κB ,which may influence the progress of alveolar inflammation and silicosis fibrosis .

Objective To investigate the status quo of returning to the society of middle-aged and young patients undergoing peritoneal dialysis based on the health empowerment theory. Methods Using the purposive sampling method, 11 patients were interviewed. The interview results were analyzed using Colaizzi analysis and the keywords were extracted. Result A total of 9 keywords were extracted, including beliefs and attitudes ( the sense of responsibility, economic burden and social needs to be met);knowledge and ability ( ability to maintain normal peritoneal dialysis but lack of the ability to solve related complications and decreased work ability after returning to society);related to action and performanc ( limited occupational self-development after returning to society,related to social support and resources:more social support, guidance in chronic disease management and proper social welfare). Conclusions Returning to society can improve the living conditions of middle-aged and youth patients with peritoneal dialysis although they can run into troubles in economic conditions, fatigue, and lack of disease management knowledge and ability. Medical workers should provide them with instructions on disease management knowledge, strengthen social support system other than their families and help them out of the troubles so that they can return to society and enhance their life of quality.

Objective To investigate the clinical features of multiple endocrine neoplasia ( MEN) associated with pheochromocytoma and anesthetic management during perioperative period. Methods Medical records of 12 patients who were operated upon for MEN associated with pheochromocytoma in our hospital from April 1977 to April 2001 were reviewed retrospectively. The demographic data, clinical manifestation, family history, biochemical examinations, type of MEN, the order of different surgical procedures for patients who had multiple operations and changes in hemodynamics were collected and analyzed. Results The 12 patients accounted for 5.6% (12/213) of the patients with pheochromocytoma admitted in the same period. Nine of the 12 patients had a diagnosis of MEN Ⅱa (Sipple syndrome) and three mixed MEN. Four patients with MEN type II a had a positive familial history. Five patients with other coexistent endocrine disorders underwent the excision of pheochromocytoma first, and only two of them had hypertensive symptoms when they were admitted. Seven patients without a history of hypertensive episodes received surgical treatment for pheochromocytoma as a second operation. The excision of pheochromocytoma was performed under general anesthesia ( in 8 patients ) or epidural anesthesia (in 4 patients). Marked hemodynamic fluctuations were recorded in 8 patients. There was no death.Conclusion Pheochromocytoma associated with other endocrine disorders in MEN may manifest itself as the main clinical symptom or most frequently as an occult tumor. Recognition of this feature is of importance to the improvement of diagnosis and treatment of both pheochromocytoma and MEN.

Objective To evaluate the impact of play therapy to the pain and the compliance of hospitalized children during tht course of lumbar puncture operation.Methods Divided 60 children with lumbar puncture operation into the intervention group (30 cases) and the control group(30cases)randomly.Routine cares were used in the control group,while the play therapy was used in the intervention group in addition during the course of lumbar puncture operation.Results There were statistical significance in the comparisons of the changes of respiratory rate and pulse rate during the preoperative and intraoperative of lumbar puncture between the two groups,P＜0.01.There were also significant differences in the comparisons of subjective and objective pain score as well as the puncture compliance in the lumbar puncture operation.The score of FLAFF scale and the Wong-Baker scale in the intervention group was (2.52 ± 1.37) and (3.59 ± 1.15) respectively,which was significant lower than that of in the control group,(4.22 ± 1.97) and (4.93 ± 1.71),the difference was significant,P＜0.01.Conclusion Play therapy can relieve the pain of children with lumbar puncture operation,reduce the changes of the vital signs,promote the puncture compliance and shorten the time of the whole operation completeness.

Objective To analyse the survival time and related factors of patients with brain stem glioma who received 3DCRT.Methods Thirty-six patients with brain stem tumor were admitted from October 2004 to December 2008 and all received 3D-CRT with the dosage (50-54 Gy,25-30 f,5-6 weeks).During treatment,the patients’ outcomes were analyzed by observing the changes of symptoms,signs and adverse radiotherapy reaction and all of them were followed-up in the next 3 years.The survival data were analyzed by Kaplan-Meire method.Results The median survival time was 9 months in the 23 pediatric patients and 15 months in 13 adult patients.One-,two-and three-year survival rates between pediatric group and the adult group were 43.5 ％ (10/13) vs 76.9 ％ (10/13),26.1％ (6/23) vs 46.2 ％ (6/13),8.7 ％ (2/23) vs 38.5 ％ (5/13).Karnofsky performance scale score at admission (x2 =20.059,P =0.000),tumor site (x2 =17.585,P =0.000),growth pattern (x2 =21.247,P =0.000) were associate with survival time.Conclusion 3DCRT is an effective therapy to brain stem glioma,childhood onset,pontine glioma,diffusion style and Karnofsky performance scale less than 80 are risk factors of poor prognosis.

Objective To determine the effect of lean mass and fat mass on bone mineral (BMD) in postmenopausal women of different age groups.Methods A total of 287 postmenopausal women (aged 50 years and over) participated in this study.Individuals were divided into 4 age groups by decades:group 1,50-59 yr (82 cases); group 2,60-69 yr (73 cases); group 3,70-79 yr (66 cases); group 4,80 years and over (66 cases).The BMD of lumbar spine (L2-4),left femoral neck and total hip were measured by dual-energy X-ray absorptiometry.Fat and muscle mass were analyzed by its analysis function and the percent of fat mass and muscle mass were calculated.Then data were processed by the SPSS 18.0 programme.Results One linear regression analysis showed that the L2-4 BMD was significantly associated only with body composition of trunk,while femoral neck (FN) and total hip (TH) BMD were respectively associated with body composition of different parts in group 1.L2-4 BMD was significantly associated only with trunk fat mass and muscle mass (r=0.27,0.25,both P＜ 0.05),but there were no relationships between BMD of FN and TH and body composition of different parts in group 2.The BMD of L2-4,FN and TH were significantly respectively associated with body composition of different parts in group 3 and 4.Conclusions In postmenopausal women,fat mass and muscle mass play an important role in BMD.In postmenopausal women aged 60-69 yr,the body composition has a minimal impact on BMD,and hormone replacement therapy may be the best for osteoporosis prevention and treatment in this period.Different exercise and loosing of weight in postmenopausal women of different ages can prevent osteoporosis and fragility fractures.

Objective To explore the relationship between plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) level and the location and prognosis of acute ST-segment elevation myocardial infarction (STEMI) in elderly people.Methods From May 2012 to April 2014, the 137 elderly patients (aged≥60 years) with acute STEMI within 24 h after symptoms onset admitted in cardiovascular department of Ningbo First Hospital were selected as acute myocardial infarction group (AMI group), and 40 elderly healthy people (age≥60 years) as control group.The plasma NT-proBNP levels were detected by enzyme linked immunosorbent assay(ELISA), and compared between the two groups.The patients in AMI group were classified into four subgroups: anterior AMI group (A group, n=44), anterolateral AMI group (B group, n=21), anterior septal AMI group (C group,n=18) and inferior AMI group (D group, n=54), and the changes of plasma NT-proBNP levels in different infarction location were explored.Meanwhile, all patients were followed up for 30 days and 1 year to observe major adverse cardiac events (MACEs) and mortality rate, then to explore the relationship between plasma NT-proBNP level and prognosis in elderly people with STEMI.Results The plasma NT-proBNP levels were significantly higher in AMI group than in control group [(1 406.2±1 322.5)ng/L vs.(63.7±18.5) ng/L, P＜0.01].The changes of plasma NT-proBNP levels in high-to-low sequence were from A group to B group to C group to D group and to control group (P＜0.05).At 30 days, the plasma NT-proBNP levels were higher in death group than in survival group (P＜0.05), and were higher in MACE group than in non-MACE group (P＜0.05).At one year, there were no significant differences in plasma NT-proBNP levels between death group and survival group (P＞0.05), and the plasma NT-proBNP levels were higher in MACE group than in non-MACE group (P＜0.05).Conclusions In elderly STEMI patients, there is a correlation between plasma NT-proBNP levels and infarct location, with the highest NT-proBNP level in anterior AMI.The plasma NT-proBNP level could predict MACE.

ObjectiveTo explore the effect of system reading therapy on alexia after stroke.Methods104 stroke patients with alexia were divided into two groups: observation group(51) and control group(53). General speech training were used for the two groups, while the observation group received system reading training at the same time, all for 30 minutes, once a day for 1 month. Chineses Standard Aphasic Examination was applied to assess the reading ability before and 1 month after treatment.ResultsThere are three kinds of alexia in the patients: frontal alexia, alexia with agaphia, and subcortical aphasic alexia. Reading ability improved in the two groups (P<0-01), but the observation group was better than the control group(P<0-05).ConclusionSystem reading therapy is very helpful to improve reading ability of stroke patients with alexia.
