Objective To analyze the clinical,demographic and pathologic features of symmetric acral keratoderma.Methods Totally,62 outpatients with symmetric acral keratoderma were collected at the Dongguan Hospital for Chronic Disease Prevention and Control from May 2003 to June 2012.Data on these patients,including demographic information,family history,physical and pathological examination findings,were reviewed.Results There were 55 males and 7 females among these patients.The age at onset and disease duration varied from 4 to 53 years (average: 24.02 years) and from 15 days to 10 years (average: 26.65 years) respectively.Characterized manifestation was brown keratinized patches on the dorsum of hands and digits,wrists,elbows,knees,ankles,and along the lateral margin of palms,which became white 3 to 6 minutes after immersing in water.Lesions usually resolved spontaneously in winter.Microscopic examination of lesions for fungal elements was negative.Histopathology revealed epidermal hyperkeratosis,acanthosis and mild papillomatous hyperplasia as well as dermal infiltrates with a few lymphocytes.Conclusion Symmetric acral keratoderma is a skin disease characterized by symmetric acral keratosis with apparent seasonality.

Objective To explore the clinical features and diagnosis of pulmonary sarcoidosis.Methods The data of 60 cases of pulmonary sarcoidosis confirmed by pathology was reviewed to determine the clinical features and the value in the diagnosis of sarcoidosis.Results The main clinical manifestations of sarcoidosis included bilateral hilar and mediastinal lymphadenopathy.The results of lung function tests showed that these patients had restrictive ventilating obstacles with decreased DLCO.The diagnosis was confirmed in 80% of the bronchial mucosa biopsies and 77.8% of the transbranchial lung biopsies through fiberotic bronchoscopy,87% of the biopsies of peripheral lymphnodes and 87.5% of the subskin nodes biopsies.Conclusion Nonspecific constitutional symptoms may occur in the cases of sarcoidosis.To the diagnosis of intrathoracic sarcoidosis,peripheral lymph nodes biopsies,the bronchical mucosa biopsies and TBLB are the convenient methods with highly definite diagnosis rate and microinvasion in clinical practice.

The fibrinolytic function of 98 patients with SLE were determined by spectrophotometric assay and immunodiffusion, 19 patients were observed before treatment, 1 month after treatment and 3 months after the disappearance of clinical symptoms. The results showed that the low level of fibrinolytic function correlated to the severity and the refractoriness of the disease, the activity of plasminogen activator inhibitor (PAI) was significantly increased in all patients. The activity ratio of tissue-type plasminogen activator (t-PA): PAI was significantly lower than normal level in the patients with lupus nephritis, not only the activity of PAI increased significantly, but also the activity of t-PA was significantly decreased, so the activity ratio of t-PA: PAI became much lower, the result suggested that it was related to the refractoriness of the disease. In patients in clinical remission, although the activity of PAI was still higher than normal level, the activity of t-PA was also significantly increased, therefore, the activity ratio of t-PA: PAI was nearly normal.

Objective:This paper aims to explore the relationship between the residents’ health and economic de-velopment to provide a scientific basis which will promote the coordinated economy and health development. Methods:Adopting the entropy method, we could calculate the comprehensive health evaluation index. In combining the co-inte-gration and error correction models, we could analyze the long-term and short-term relationships between our country residents’ level of health since 2000 and the national macro-economic development information. The Granger causality test served as a good method used in testing the casual relationships. Results: The health and economic development has a co-integration relationship which is -0. 6216 in the short-term correction. The economic development extent is the Granger cause of residents’ health status. Conclusion:There is not only a long-term equilibrium, but also a short-term relationship between the residents’ health and economic development in our country. The economic growth pro-motes residents’ health status while the promotion of residents’ health to economic growth is not obvious.

Objective To detect mutations in the filaggrin (FLG) gene and expressions of FLG and loricrin in patients with ichthyosis vulgaris (Ⅳ),and to investigate their clinical significance.Methods Tissue specimens were resected from the skin lesions of 10 patients with Ⅳ and normal skin of 14 healthy human controls,and immunohistochemical SP method was used to detect the expressions of filaggrin and loricrin.The expression intensity was determined by the Image-Pro Plus (IPP) software,and expressed as positive units (PU).Blood samples were collected from 10 patients of Han nationality with Ⅳ and 100 healthy human controls followed by DNA extraction.PCR and DNA sequencing were performed to detect the presence of 13 mutations (3321delA,441delA,1249insG,E1795X,S3296X,R501X,2282de14,R2447X,S2889X,7945delA,3702delG,Q2417X,R4307X) in the FLG gene.Results FLG was mainly expressed in the cytoplasm of keratinocytes in the stratum corneum,granular layer,prickle layer and basal layer,and loricrin was observed in the cytoplasm and nuclei of keratinocytes in the granular layer,prickle layer and basal layer,in both the lesional and normal skin.Compared with the normal skin,the lesional skin showed significantly weaker expressions of FLG (0.208 2 ± 0.008 0 vs.0.230 0 ± 0.0228,t =3.30,P ＜ 0.01) and loricrin (0.137 0 ± 0.011 2 vs.0.149 3 ± 0.007 3,t =3.07,P ＜ 0.01).Sequencing analysis identified two mutations,including 3321delA in 7 patients and 441delA in 2 patients.No mutations were detected in the healthy controls.Conclusions The 3321delA and 441delA mutations in the FLG gene may represent the most frequent genetic cause of Ⅳ in patients of Han nationality.The low expressions of FLG and loricrin may be associated with the impairment of skin barrier function in patients with Ⅳ.

Objective:To investigate the relationship between VitD 3 concentration and glucose and insulin levels of OGTT in patients with CKD 3-5 stages.Methods: We included the patients with CKD 3 and 4 and 5 stages who fulfill the including standard.All patients were recorded the concentrations of [1,25 (OH):D3]concentration of glucose and insulin at fasting ,postprandial 1 h,2 h during OGTT and concentration of glycosylated hemoglobin level ,C peptide concentration.We performed the correlation analysis about [1,25 (OH):D3],glucose and insulin.Results: We totally included 91 patients with 3-5 stages CKD into our study.The D3 concentration of stage 3 were 160.9-261.3 mmol/L[(218.38±8.67)mmol/L] of stage 3,75.2-166.3 mmol/L[(117.01±4.72) mmol/L] of stage 4 and 11.8-96.5 mmol/L[(41.91±12.83)mmol/L] of stage 5 (P<0.05).The average concentrations of serum glucose at fasting,1 h after the meal and 2 h after the meal was(4.74±0.21)mmol/L,(8.31±0.43)mmol/L and(7.36±0.32)mmol/L in 3 stage and (4.92±0.25) mmol/L,(9.14±0.15) mmol/L and (9.14±0.39)mmol/L at 4 stage and (4.81±0.13)mmol/L, (10.72±0.41)mmol/L and (10.72±0.49)mmol/L at 5 stage (P<0.05).The average concentrations of insulin during OGTT at fasting,1 h after the meal and 2 h after the meal was (6.58±0.32) μU/L,(57.78±5.63)U/L and (42.77±8.45)U/L in 3 stage (6.03±0.53)U/L,(55.69±7.35)U/L and (62.52±5.39)U/L in 4 stage and (6.12±0.65)U/L,(62.82±9.73)U/L and (77.34± 8.62)U/L in 5 stage (P<0.05).Correlation analysis shows that the concentration of 1,25 (OH):D3 of different stages of patients with CKD and vitamin D 3 concentration and glucose tolerance test was found to be inversely associated with the insulin levels ( P<0.05 ) . Conclusion:There are obvious differences of concentration of vitamin D 3 between patients with 3-5 stages of chronic kidney disease (CKD).There also showed a negative correlation relationships between glucose and insulin levels ,and vitamin D3 concentration and glucose and insulin levels at OGTT of patients with 3-5 stages CKD.

Objective To investigate the reliability of intramyocardial electrogram (IMEG) in monitoring acute rejection after human heart transplantation. Methods From June 2004 to March 2009, 32 patients underwent orthotopic heart transplantations. During the operation telemetric pacemakers were placed under the skin of the body with connected bipolar electrodes implanted into epimyocardium. Postoperative IMEGs, including the autonomous IMEG and ventricular evoked response (VER) were recorded routinely. The endomyocardium biopsy (EMB) was taken routinely and performed once again when positive IMEG results or other positive signs were observed. Results Totally 523 IMEGs has been produced, 41 of VERs were recorded together with autonomous IMEGs and EMBs, in which 17 EMB specimens were confirmed positive and 24 negative. AUC of QRS was 0.7537, Se was 88.24%, Sp was 62. 50%; AUC of Tslew was 0. 9081, Se was 94. 12%, Sp was 87. 50%. QRS and Tslew had significant difference in AUC of ROC, with x2 = 4. 22, P＜0. 05; AUC of combined diagnostic index (positive when either QRS or Tslew is positive and negative when both values are negative) was 0. 7917, Se was 100.00%, Sp was 58. 33%. Conclusion QRS amplitude of the autonomous IMEGs, Tslew of VERs and combined diagnostic index are reliable indexes for monitoring acute allograft rejection after human heart transplantation. Furthermore, Tslew has a better prognostic value than QRS.

Objective To investigate the perioperative hemodynamic features of mitral replacement of patients with small left ventricle.Methods Patients with left ventricle end-diastolic dimension (LVEDD) less than 40mm received mitral replacement sur- gery were divided into big size M-2 group and small size M-1 group.The perioperative echo results were analyzed with SPSS software. Results The big size M-2 group has lower trans mitral gradient [ (5.9?1.6) mm Hg vs.(10.7?3.2) mm Hg],larger in vivo va- lular acre[ (2.9?0.2) cm~2 vs.(2.6?0.2) cm~2],and high mitral match index [(1.92?0.23) cm~2/m~2 vs.(1.73?0.18) cm~2/m~2 ].Conclusion With the meticulous perioperative treatment and myocardial protection,the patients with small left ventricle should also receive a mitral replacement as big as possible to achieve the ideal hemodynamics results.

Objective To conclude the preliminary results of aortic valve repair with autopericardium.Methods After routine median sternotomy the pericardium was isolated and immersed into the 0.6% glutaraldehyde immersion for 10 minutes, then rinsed off before use.Conventional extracorporeal circulation was established and diseased aortic valves were removed.The curves lengths between three commissures measured with the specific sizers.The corresponding size of the pericardial patchs was used to cut the new aortic leaflets.The continuous Johnson Prolene 4-0 sutures were used to fixed the new aortic valve leaflets to the anulus.Another new 4-0 prolene suture were used to fix the new three commissures outside the aortic wall with mat.The new mat stripes were used to fix the sinus in condition with the aortic sinus dilation or bileaflets malformation.Results Since 2015 October total 27 patients received aortic valve repair with autologous pericardium.The age was in the range of 27 to 60 years old including 18 female and 9 male.There were 7 cases diagnosed as aortic valve stenosis and 20 cases aortic insufficiency.And there were 3 cases bileaflets aortic valve deformity.The mean bypass time is(104±25)mins.Postoperative esophageal ultrasound showed good coaptation of the aortic valve without significant regurgitation.The mean transvalve gradient was(8.5±3.2)mmHg(1 mmHg=0.133 kPa).In the early stage one case diagnosed with aortic valve stenosis and regurgitation received monocusp repaired with autologous pericardial leave.But there was still moderate aortic regurgitation and had to receive the aortic valve replacement.All patients recovered well and were treated with Aspirin for 6 months.The followed up lasted for 3 to 13 months.Mean aortic occlusion time was(104±25) minutes.The patients were followed up for 3-13 months, the cardiac function and aortic valve function were stable, and no gradient increased.Conclusion It is relatively simple to perform the aortic valve repair with individual autologous pericardial sizer technique and the primary clinic results are satisfactory.It is worthy of further study and long-term follow-up.
