Objective To repair and reconstruct severe burn wounds on face,hands and joints with the principles and techniques of plastic and aesthetic surgery.Methods Twenty three burn victims in a single batch were transferred from a remote area to our Burns Institute on post burn day 2,June 28,2006.All the patients were males aged from 17 to 46 years,with a mean of 24.4?6.3 years,the mean total burn area was 15.7%?13.9% TBSA(ranged from 6% to 75%),with moderate to severe inhalation injury,and fourteen of them had received tracheostomy.The burn areas on face ranged from 0.5% to 3% TBSA,and all of them were deep second or third degree burn.The burn areas on hands ranged from 1% to 4% TBSA of deep second or third degree.On post burn day 3,the patients received escharectomy or tangential excision of eschar on hands followed by split thickness skin grafting with the principles and techniques of plastic and aesthetic surgery.During post burn week 2 to 3,the eschar on the faces were peeled off,followed by split-thickness skin grafting according to the principles and techniques of plastic and aesthetic surgery.Results All the wounds on the face and joints were repaired successfully,the configuration and functions were satisfactory.Conclusion It is feasible to repair the burn wounds on face and joints with the principles and techniques of plastic and aesthetic surgery for the burn patients of mass fire catastrophe.

Anxiety is usually generated because of the threatened feeling. The data of electrocardio, respiration, blood volume pulse and skin conductance signals were collected. The arithmetic of Relief were used for the feature selection and combined with k-Nearest Neighbor (kNN) arithmetic and Support Vector Machine (SVM) arithmetic for classification. The results show that the combination of Relief-SVM is better than combination of Relief-kNN on the recognition of anxiety state. The emotion recognition based on multi-physiological signals is superior to that based on one single signal.

Objective To investigate the clinical value of multiband mucosectomy (MBM) for the treatment of early esophageal cancer and precancerous lesions.Methods The clinical data of 43 patients with early esophageal cancer or precancerous lesions (including 13 cases of early esophageal cancer and 30 cases of precancerous lesion) who were admitted to the Tengzhou Central People's Hospital from January 2010 to January 2011 were retrospectively analyzed.A total of 51 lesions were confirmed by preoperative endoscopy and mucosal biopsy,and then were treated by MBM.Results A total of 52 MBM procedures were carried out,and 180 lesions were resected.The sizes of the lesions ranged from 10 mm × 8 mm to 25 mm × 23 mm,and the mean operation time was (37 ± 5)minutes.The complete resection rate was 92.2％ (47/51).The submucosal layer of 1 patient was invaded by squamous cell carcinoma postoperatively,and the patient was treated by operation;1 patient wth squamous epithelium carcinoma was treated by radiotherapy at 2 weeks after MBM ; the other 2 lesions were treated by argon plasma coagulation (APC).Four lesions with bleeding were detected during 52 MBM procedures,and no esophageal perforation was detected during MBM.Early complications consisted of delayed bleeding (1 patient,cured by APC) and slight esophageal stenosis (1 patient,recovered at postoperative month 6).The accurate rate of pathological examinations was 51.0％ (26/51).Forty-three patients were followed up for 1 year,3 patients with tumor recurrence were treated by MBM or APC.No death occurred during the followup.Conclusion MBM is a safe and effective technique for the treatment of early esophageal cancer and precancerous lesions.

Objective To investigate the expression of granulocyte macrophage-colony stimulating factor(GM-CSF)in skin lesions and sera of patients with pustular psoriasis and psoriasis vulgaris.Methods Tissue specimens were obtained from the lesions of 15 patients with pustular psoriasis,15 patients with psoriasis vulgaris and 15 normal human controls.Immunohistochemistry and dual antibody sandwich enzyme-linked immunosorbent assay(ELISA)were carried out to detect the levels of GM-CSF in the tissue and serum specimens from the patients and normal human controls,respectively.Results Significantly higher levels of GM-CSF were observed in the tissue and serum specimens from patients with pustular psoriasis and psoriasis vulgaris compared with the normal controls(all P ＜ 0.01),as well as in those from the patients with pustular psoriasis compared with the patients with psoriasis vulgaris(both P ＜ 0.01).Conclusion GM-CSF may be involved in the pathogenesis of psoriasis.

Objective This study aimed at soliciting preliminary data about the feasibility and effectiveness of a computer-aids for HIV/AIDS voluntary counseling and test (VCT) developed by ourselves and inform further refinement and evaluation of the software.Methods Informant qualitative interviews,structured questionnaires and audio-recorded counseling cases were used in gathering data.Pre-and post-intervention statistical comparisons of quantitative data and expert reviews of qualitative materials were performed in deriving evaluation outcomes.Results Application of the software increased per episode counseling time from 5.55 minutes to 10.73 minutes;coverage of critical counseling components by over 1.5 folds;and successful memory of core knowledge items from 40.51% to 86.34%.Most participating counselors and clients perceive the software as feasible and effective.Conclusions The software put forth merits further researches.

Objective This study aims at developing a computer aid for performing HIV/AIDS counseling and test,so as to standardize VCT operating procedures and help frontline counselors provide high quality VCT service.Methods Rapid prototyping was employed in which primitive VCT standard operation procedure (SOP) and prototype software were generated through literature reviews,counseling case studies and expert panel activities first and then refined through consecutive rounds of piloting at various VCT settings.Results A pragmatic SOP and computer-aid for performing routine VCT services were put forward.It consists of 5 main application modules including performing counseling,making appointment,managing data,developing counseling skill and setting system parameters.Conclusions Our study suggests that standardization and computerization of complex VCT service is feasible and the system we had produced provides a new means for improving the service.

Objective To investigate the relationship between coexisting depression and anxiety (CDA)and quality of life of female nurses in general hospitals.Methods Seven hundred and ninety-three female nurses completed Zung' s Self-rating Depression Scale (SDS),Zung' s Self-rating Anxiety Scale (SAS) and the World Health Organization' s Quality of Life Questionnaire-Brief Version (WHOQOL-BREF).According to the cut-off scores of SDS and SAS,all subjects were divided into 4 groups (non-depression and non-anxiety,pure depression,pure anxiety,and CDA).Group differences in SDS,SAS and WHOQOL-BREF scores were compared.Results Of these 4 groups,CDA group had the highest SDS and SAS scores (P ＜ 0.001) (SDS scores:(34.3 ±5.4),(47.1 ±4.0),(39.4 ± 2.4) and (49.7 ±4.2)) and the lowest WHOQOL-BREF scores (P≤0.033)(WHOQOL-BREF physical domain scores:(15.6 ± 2.0),(13.8 ± 2.0),(13.6 ± 1.6) and (12.1 ± 2.0)).The corresponding stratification analysis (controlling for confounding factors) showed consistent results.Conclusion CDA nurses have the most severe depressive and anxious symptoms and the worst quality of life,and thus are the key target population of mental health service.

Objective This study is to investigate the protective effect of creatine phosphate so-dium on circulatory function in unilateral total knee replacement surgery using bone cement implanta-tion.Methods Forty patients undergoing unilateral total knee replacement surgery with bone cement were randomly assigned into 2 groups:test group (group CP,n=20)and control group (group NS, n=20).The easophageal doppler ultrasound probe was placed at the level of the third rib transorally after induction in each patient.In group CP,creatine phosphate sodium (2 g in 100 ml normal saline) was infused (within 30 min)at 30 min before the operation,as well as normal saline 100 ml in group NS.SBP,DBP,HR,SpO2 ,PET CO2 and BIS were monitored and recorded before (T0 )and 1 (T1 ),3 (T2 ),5 (T3 ),10 (T4 )min after insertion of bone cement.Cardiac output (CO),stroke volume (SV)and left ventricular end-diastolic volume (LVEDV)were simultaneously monitored and recorded with esophageal doppler ultrasound.WhileⅡ-lead electrocardiogram were recorded to monitor ven-tricular arrhythmia perioperatively.Results SBP,DBP and HR decreased at T2 and T3 in group NS, and were lower than those in group CP (P <0.05 );Meanwhile,compared with group CP,CO and SV were significantly lower,while LVEDV was significantly higher in group NS (P <0.05 ).Com-pared with T0 ,CO and SV decreased and LVEDV increased at T2 and T3 in group NS (P <0.05 ). After insertion of bone cement,the incidence of arrhythmia in group CP was obviously lower than that in group NS (P < 0.05 ).Conclusion Pretreatment with creatine phosphate sodium can effectively prevent the incidence of bone cement implantation syndrome (BCIS)by stabilizing hemodynamic in elderly patients undergoing total knee replacement with bone cement.

Objective To study clinicopathologic features of ALK-positive large B-cell lymphoma.Methods The clinical data,histopathological characteristics,immunophenotype and fluorescence in situ hybridization (FISH) result of a patient with ALK-positive large B-cell lymphoma were analyzed and discussed combined with related literatures.Results A 30-years-old male patients with the left neck lymphadenectasis was studied.Histological evaluation revealed the tumor grew in sheets in the nodal,with round nuclei,dispersed chromatin,a single prominent central nucleolus and moderate amounts of eosinophilic to amphophilic cytoplasm.The neoplastic cells exhibited immunoblastic/plasmablastic morphology.Immunohistochemistry measurement showed that the tumor cells were marked positively by CD138,ALK-1,CD45RO,CD4,Perforin,CD117 and Kappa proteins,while negatively by CD3,CD8,CD20,CD30,CD38,CD57,CD79a,Pax-5,EMA and AE1/AE3 proteins.FISH test demonstrated the presence of ALK gene translocation.The patient was given 4 cycles of CHOP chemotherapy after surgery.However,the conditions deteriorated after 4 months.Now the patient continued to receive treatment.Conclusion ALK-positive large B-cell lymphoma represents a distinct variant of diffuse large B-cell lymphoma,and the tumor has special histological features along with a distinct immunophenotype and ALK gene rearrangement.
