Objective To study the methods and clinical effects of joint expansion of double fascia flaps wrapping the Medpor to perform full-ear reconstruction on congenital microtia deformity.Methods 60 patients with congenital microtia deformity were selected.including 22 left ears and 38 right ears.Majority had loss of ear auricle or only partial earlobe.Phase Ⅰ procedures included:temporal-parietal branch was used for the vascular pedicle,and mastoid area behind the ear was moved and expanded for fascia flap.Phase Ⅱ included:the joint expansion of double fascia flap wrapped Medpor to do full-ear reconstruction.Results Flaps survived and no complications for all 60 patients.Reconstructed ears had lifelike appearance and clear anatomical structures.Auriculocephalic angulars positions and sizes were consistent with the healthy ears.None of them had exposed prosthesis and scar contraction.Three-dimensional shapes were good.Conclusions Joint expansion of double fascia flap wrapping Medpor could avoid the chest wall deformity and exposed prosthesis.The fine structure of the reconstructed ear is satisfactory.

Objective To study the methodology and effect of auricle reconstruction with prefabricated expanded fascial flap in temporal and parietal area and skin flap in mastoid area, covered on the Medpor support. Methods Thirty cases of congenital vestigial auricle were involved in this study. The operations were divided into two stages: in the stage I,the temporal and parietal superficial fascia flap was cut with a vascular pedicle in the parietal and temporal superficial area, which was implanted under the skin of mastoid, and then both layers of those were expanded at the same time; in the stage II, this fascial skin flap was cut down and covered on the whole Medpor support to rebuild the man-made auricle. Results Thirty cases were successful after following-up for 6 months to 3 years. Their auricle shapes were vivid; their skin color was normal, and it had no any difference from all around skins, or no any appearance of the support. Conclusions With best understanding the biological characteristics of the Medpor support and choosing the suitable procedures and using the prefabricated expanded support, we could minimize the surgical complications in this operation. The results show that this procedure is satisfactory, without any necrosis of flap, swelling of contour, or appearance of the support. The combination of two flaps is the best method for the auricle reconstruction.

Polyphyllin Ⅱ showed good linear relationship in the range of 0.640 5–6.405 μg (r=0.999 8), and the average recovery was 96.41% (RSD=1.67%, n=6). Conclusion The method is simple, with good repeatability and accurate results, which can be used to determine the contents of polyphyllin Ⅰ and Ⅱ in Kangkeling Mixture.

Objective To understand the self-assessment of health status,health effects,active awareness of weight control and behavior of urban occupational populations with different body mass index (BMI ).Methods With random cluster sampling survey in two monitoring areas,1 175 cases aged 18 to 45 were selected,consisted of public servants, enterprise administrators and institution personnel groups.Results In the urban occupational populations in Hangzhou City,the overweight rate was 21.70%,and the obesity rate was 6.04%.The awareness rate of underweight,normal weight,overweight and obesity crowd for health effects to the body was 98.95%,98.81%,96.08% and 95.77%respectively;and for mental health effects was 90.53%,92.44%,83.92% and 81.69% respectively;and for weight control confidence was 82.11%,79.18%,72.94%and 50.70%respectively.The awareness rate decreased with increased body weigh with significant difference (P<0.05 ).There was no significance differences in weight control behaviors and accumulation of weight control behaviors (P >0.05 ).Conclusion There was significantly difference in people with different BMI about the awareness of overweight obesity impact on personal health and weight control activity,but there was no difference in that of weight control behaviors.

Objective To learn the smoke-free environment and smoking status at or below county-level governments of Zhejiang Province, and to promote a smoke-free government.Methods By multi-stage random sampling method, 4 cities were selected in Zhejiang Province, then 4 counties were selected in 4 cities, finally12 governments were selected in 4 counties.With the methods of field observation,interview and questionnaire survey,smoke-free environment and smoking behavior , tobacco related knowledge of civil servants were investigated.Results A total of 12 governments and 405 civil servants were investigated.The smoke-free environment of 12 governments were relatively well.The total smoking rate of civil servants was 17.78%, and the highest was 26.67% in Jiande City, and the lowest were 9.00% in Zhuji City.For the civil servants ,male(26.62%), aged 50-(40.74%),divorced or widowed(40.00%),graduation of technical secondary school (33.33%),cadre of section rank(57.14%),above 20 years' work(28.81%),smoking anywhere at home(50.00%), smoking in certain areas at work(22.95%)were significantly higher.The rate of cognition on the hazards of smoking was lower among the smokers than that of non-smokers (P<0.05).The rate of agreement on MPOWER tobacco control strategies and smoking bans in public places were lower among the smokers than that of non-smokers (P<0.05).Non-conditional logistic regression analysis showed that age of 30-39(OR=9.87,95%CI:1.45-67.29),50-(OR=9.87,95%CI:1.45-67.29), smoking anywhere at home(OR=12.28,95%CI:2.95-51.18),and smoking in certain areas at home(OR=6.57,95%CI:3.07-14.08) may be the risk factors about smoking behavior.Conclusion The situation of smoking control at or below county-level governments in Zhejiang Province was good, and smoking rates has declined.But tobacco related knowledge and behavior of civil servants were relatively insufficient.Aiming at the problems found in the investigation, it is necessary to strengthen education on smoking control among civil servants, and to promote a smoke-free government.

OBJECTIVETo estimate the size of female sex workers and clients in Taizhou city.

METHODSA household survey using network scale-up method (NSUM) was conducted among the 3000 community residents in Taizhou city from August to October in 2011, which aimed to estimate the social network size (c value) of Taizhou residents, and the c value was adjusted by demographic characteristics, back estimation and outlier elimination. Using the adjusted c value, the number of acquaintance of female sex workers or clients and the respect level toward female sex workers or clients were used to estimate the size of female sex workers and clients.

RESULTSA total of 2783 valid questionnaires were collected, among which 1380 (49.6%) were collected from Taixing city, 1403 (50.4%) were collected from Jingjiang city. 1334 respondents were male (47.9%) and 1449 (47.9%) respondents were female. The mean age was (39.4 ± 10.7) years. The average personal social network size using original data for Taizhou residents was 525, which differed from place, sex, age, educational level and marriage status. Using the remaining known populations through back estimation, the social network size was 419 and became 424 after the elimination of outliers. The estimated population size for female sex worker was 6370 (95%CI: 5886 - 6853), which accounted for 0.52% (6370/1 229 980) of the total number of female aged from 15 to 49. The estimated population size for clients was 15 202 (95%CI: 14 560 - 15 847), which accounted for 1.28% (15 202/1 190 340) of the total number of males aged from 15 to 49 and the ration of clients to female sex worker was 2.39:1.

CONCLUSIONNSUM is an easy and quick way to estimate the size of female sex workers or clients, but the estimated sizes are subject to bias and error due to estimate effect and sample representativeness.

BACKGROUNDCavity reconstruction after benign bone tumor removal is varied and controversial. Allograft is widely used but is associated with complications. New bone substitutes, such as calcium sulfate artificial bone, have been introduced for bone tumor operation. However, the bone healing response of artificial bone has not been compared with allograft bone. We therefore compared calcium sulfate grafts (study group) with bone allografts (control group) for the treatment of benign bone tumors.

METHODSWe retrospectively reviewed 50 patients who underwent calcium sulfate reconstruction and 50 patients who underwent allograft cancellous bone reconstruction. The two groups were well matched. The mean follow-up time of the study group was 19.9 (12-55) months. We investigated bone healing response, complications, and factors affecting bone healing.

RESULTSAt the last follow-up, 84% (42/50) of cases in the study group and 62% (31/50) of cases in the control group had achieved clinical healing (P = 0.013). The initial healing rate showed no significant difference between the two groups (100% vs. 96%, P = 0.153). The mean healing times for calcium sulfate and allograft bone were 9.6 (3-42) months and 13.8 (3-36) months, respectively (P < 0.01). Complications in the study group were minor and resolved. Implant volume was a significant factor affecting bone healing.

CONCLUSIONThe calcium sulfate bone substitute showed a satisfactory healing outcome and safety profile in reconstruction of bone defects after benign bone tumor curettage, especially in smaller cavities.

OBJECTIVETo investigate the effects of Mycobacterium tuberculosis on apoptosis of mouse dendritic cells (DC 2. 4) and the activation of caspase-3, caspase-8.

METHODSMycobacterium tuberculosis H37Rv strain was co-cultured with DC 2. 4 cells. The morphological changes of DC 2. 4 cells were observed with fluorescence microscope after DAPI staining and transmission electron microscope. The apoptosis of DC 2. 4 cells were examined by DNA agarose gel electrophoresis. The activities of caspase-3 and caspase-8 were detected by colorimetric assay.

RESULTSBacterial invasion was observed while DC 2. 4 cells and H37Rv were co-cultured for 2 h; and the rates of invasion were (16.1 ± 4.3)%, (35.8 ± 5.1)%, (50.2 ± 5.7)%, (58.3 ± 6.2)% and(65.9 ± 6.9)% at 4, 6, 8,10, 12 h, respectively. The phenomenon of nuclear condensation and marginalization were shown by DAPI staining and transmission electron microscope in DC 2. 4 cells at 6 h of co-cultivation with H37Rv. The characteristic bands of apoptosis by DNA electrophoresis were detected. The activities of caspase-3 and caspase-8 were increased in a time-dependent manner. The rates of DC 2. 4 cell apoptosis were (6.4 ± 2.5)%, (11.8 ± 5.3)% and (31.1 ± 8.7)% at 6 h,12 h and 24 h after co-cultivation with H37Rv, respectively. The maximal activities of intracellular caspase-3 and caspase-8 at 10 h and 6 h were (2.01 ± 0.09) U/μg and (2.40 ± 0.07)U/μg, respectively, which was significantly different compared with the control groups(P<0.05). The activation of caspase-8 was earlier than that of caspase-3.

CONCLUSIONMycobacterium tuberculosis can induce the apoptosis of DC 2. 4 cells, which is associated with the activation of intracellular caspase-3 and caspase-8.
