Objective To estimate the prevalence and associated factors of facial wrinkling in females.Methods Questionnaires were designed and delivered to collect related data on volunteers. The subjects were divided into outdoor and indoor groups. Wrinkles were classified into 9 grades based on photos taken by SIA0612 image analyzer and quantification analysis via Visioscan VC 98. SPSS 17.0 software was used to assess the associated factors of wrinkling, including sun-protective measures, skin care and cosmetology, onset age and location of wrinkles in these subjects. Results A total of 246 patients aged 19 - 71 years were recruited in this study. Sun-protective measures were applied in 13.5% of the subjects between 12 and 18 years of age,38.5% of those between 19 and 29 years of age, 39.2% of those between 30 and 39 years of age, 44% of those between 40 and 59 years of age, and in none of those between 60 and 75 years of age, 44.1% of all the subjects in the latest 5 years. Wrinkles were absent in 5.7% of the subjects, and pigmentation macules absent in 21.7%. The first development of wrinkles was mainly observed in subjects aged 30 to 35 years, and that of pigmentation macules in those aged 25 to 30 years. The most common locations of facial wrinkles, in order of decreasing frequency, were infraorbital area, lateral angle of eye, nasolabial fold, glabella in the indoor group,lateral angle of eye, infraorbital area, glabella and nasolabial fold in the outdoor group. Fishtail lines seemed to be the commonest wrinkles with an earliest onset among these wrinkles, and showed a prevalence of 100% in subjects aged 45 years or older in the indoor group, and in those aged 30 years or older in the outdoor group.Conclusions Wrinkles and pigmentation macules are dominate manifestations of skin aging in Chinese females. The onset of pigmentation macules is earlier than that of wrinkles. The main manifestations of skin aging in Chinese females, in order of decreasing frequency, are yellow-grey skin, skin dryness, roughness,leather-like appearance, teleangiectasia, and (or) severe pigmentation macules, increase in skin fragility, etc.The order and age of wrinkle appearance are different between indoor and outdoor females.

Objective To investigate the feasibility and value of CT perfusion imaging in combination of CTA 320-slice CT with dual-low-dose in detection of acute cerebral ischemia.Methods Forty patients with acute stroke underwent perfusion imaging and CTA using a single scan with 320-slice CT with dual-low-dose schedule.CTA,4D-CTA,4D-perfusion imaging and fusion images were generated at a post-processing workstation.All patients also underwent a 3.0T magnetic resonance imaging with DWI for a comparison.Quality of the images,degree of vascular stenosis,and location of ischemic lesions were evaluated.Results The vascu-lar stenosis or occlusion was found in 33 patients,8 of whom were confirmed by the DSA.The ratio of better images of CTA was 82.5%.CTP showed 297 lesions with abnormal perfusion.202 lesions were confirmed as infarct by DWI,while 95 ones were nor-mal on DWI but with increased DLY and TTP and slightly decreased CBF and CBV in 49,increased DLY and TTP and normal CBF and CBV in 21,and increased DLY and TTP and slightly increased CBF and CBV in 25.Conclusion CT perfusion in combination with CTA by 320-slice CT with dual-low-dose is feasible and useful to observe accurately the vascular structures and the ischemic status of the whole brain at early stage.

BACKGROUND: It is still controversial that interspinous dynamic stabilization system Wallis and Coflex which one can provide better clinical effects for lumbar degenerative disease.OBJECTIVE: To systematically assess the clinical effectiveness and safety of Wallis and Coflex for lumbar degenerative disease.METHODS: According to the computer-based online search of PubMed, Embase, Medline, Cochrane Library, CBM,CNKI, Wanfang Database, and VIP, articles published before August 1st, 2016 were searched. Articles about Wallis comparing with Coflex for lumbar degenerative disease were included; the quality score of methodology was assessed by MINORS. Research data abstracted and synthesized by Review Manager 5.3 were used for meta-analysis.RESULTS AND CONCLUSION: (1) Six studies were included, and all studies were designed for non-randomized controlled trial. (2) There were no significant statistical differences in Japanese Orthopedic Association, Oswestry disability index, visual analogue scale score, Prolo functional score, segmental lordosis angle, and segment movement degree. Incidence of adverse events was significantlue scale less in the Wallis group than in the Conflex group (P < 0.05).(3) There was no significant difference in clinical efficacy between Wallis and Coflex in the early and mid-term follow-up.We can conclude that Wallis may provide better clinical safety than Coflex.

Objective To investigate the guidance value of TOI classification in treating traumatic T-type atlantoaxial dislocation (ADD).Methods A retrospective case series study was made on 32 cases of traumatic TOI T-type ADD treated between January 2012 and December 2015.There were 19 males and 13 females,aged (38.4 ± 14.7) years.Fifteen cases of T1-type underwent external fixation or internal fixation without fusion,while 17 cases of T2-type underwent internal fixation with fusion.Symon-Lavender clinical standard,Japanese orthopedic association score (JOA),visual analogue scale (VAS),atlas-dens interval (ADI) and space available for the cord (SAC) were used to evaluate the therapeutic effect.Results Patients were followed up for 6-54 months (mean,32.4 months).At final follow-up,ADI was decreased to (2.3 ± 1.4) mm from preoperative (5.6 ± 1.6) mm,but SAC was increased to (15.4 ± 1.9) mm from preoperative (12.0 ± 2.9) mm(P ＜ 0.01).At final follow-up,cervical axial rotation range of motion was 102°-154° in T1-type cases and 57°-93° in T2-type cases.Range of motion for atlantoaxial joint was preserved in T1-type cases,but lost in T2-type cases.According to the Symon-Lavender clinical standard,there were 14 cases of mild disability,nine moderate disability,eight severe disability and one extremely severe disability before operation;there were 21 cases of mild disability,nine moderate disability and two severe disability at last follow-up.Significant difference was observed in the grades according to the Symon-Lavender clinical standard before operation and at last follow-up (P ＜0.05).At last follow-up,JOA score was increased to (14.6 ± 2.9) points from preoperative (9.9± 3.2) points,and VAS was decreased to (2.7 ± 1.3)points from preoperative (6.0 ± 1.6)points (P ＜ 0.01).Conclusions By using TOI classification,reconstruction of stability and improved neurological function can be achieved in treatment of traumatic T-type atlantoaxial dislocation.Non-fusion treatment of T1-type atlantoaxial dislocation can preserve range of motion for atlantoaxial joint.

Objective To explore the level and the significance of amino-terminal propeptide of procollagen type Ⅲ(P Ⅲ NP)in the serum of hypertrophic scar patients at excessive stages.Methods The serum samples of 74 inpatients admmitted in Affiliated Fosham Hospital of Sun Yat-sen University from August 2007 to August 2009 suffering from long-persisting post-burn hypertrophic scar at various stages were collected.Serum samples of 12 were normal persons were also collected and used as control group.Hypertrophic scar group were divided into 4 subgroups according to the phase of scar and the serum concentrations of P Ⅲ NP were detected using the sensitive RIA method.Results The level of PⅢ NP increases gradually during the process of immature hypertrophic scar to mature scar before it peaking in 4 to 6 months scar subgroup.The concentration of PⅢ NP degreased gradually with the maturation of hypertrophic scar.Conclusions The high concentration of PⅢNP can reflect the high level of the synthesis of type Ⅲ collagen in the tissue of post-burn hypertrophic scar.The level of P Ⅲ NP is synonymous with the ongoing process of hypertrophic scar.PⅢ NP may be a satisfactory marker in discerning the growth and development of post-burn hypertrophic scar.

Objective:To optimize the injection protocol of contrast medium for contrast-enhanced MRA (CEMRA) of pulmonary artery and to evaluate the diagnostic value of CEMRA and pulmonary perfusion imaging (PPI) in an experimental model of acute pulmonary embolism. Methods:CEMRA and PPI were performed in 6 normal pigs with different doses of gadolinium contrast agent (5ml, 10ml, 15ml, 20ml and 25ml) at an injection rate of 3ml/s, and 3 pulmonary embolism models were injected with 20 ml contrast agent at 3 ml/s. DSA was also performed for comparison. Results:The signal intensities and the signal to noise ratios of the pulmonary arteries kept increasing with the dose increase of the contrast agent, but the best angio-pulmonary contrast dose was 10-15ml (0.25-0.375mmol/kg), while the optimal dose for PPI was 15-20ml (0.375-0.5mmol/kg). Although CEMRA demonstrated less obstructed pulmonary arteries than DSA (5/10 vs 8/10)did, it detected all obstructions when combined with PPI. The pulmonary infarction zones showed wedge-shaped perfusion defects on the PPI images, with the signal intensities lower than those of the normal areas (137.86±45.32 vs 330.14±46.52, P<0.001). Conclusion:It is suggested that the optimal dose of the contrast agent is 0.25mmol/kg to 0.375mmol/kg for CEMRA, and 0.375mmol/kg to 0.5mmol/kg for lung perfusion. CEMRA combined with PPI may be better than DSA in demonstrating pulmonary embolism.

OBJECTIVETo investigate the feasibility of the composite transplantation of 1:3 meshed split-thickness autograft and acellular heterologous (porcine) dermal matrix.

METHODS9 inpatients with full thickness skin burn or hypertrophic scar were selected in this study. After the eschar or scar was excised, the wound was covered with acellular heterologous dermal matrix. Then the meshed (1:3) split-thickness autologous skin sheet was grafted on the dermal matrix. Before dressing up, the radiated pigskin was placed on the composite transplants.

RESULTSThe composite transplantation was successfully used in 9 cases. The meshed split-thickness autograft was expanded 3 times and covered the dermal matrix tightly. The clinical results of the composite transplantation were similar to that of intermediate split thickness skin graft or full thickness skin graft.

CONCLUSIONThe composite transplantation of meshed (1:3) split-thickness autograft and acellular heterologous (porcine) dermal matrix allowed the expansion of the autologous skin sheet to 3 times. The clinical results were similar to that of intermediate split thickness skin graft or full thickness skin graft.

Objective To compare the value of diffusion kurtosis imaging (DKI) mode and mono-exponential mode in predicting the response to neoadjuvant chemotherapy (NAC) for locally advanced breast carcinoma using DWI.Methods From January 1,2013 to December 31,2016,eighty patients with locally advanced breast carcinoma were enrolled into this prospective clinical study.The diagnosis was confirmed on the basis of histopathological results.The clinical stage stayed at Ⅱ or Ⅲ.The patients would receive breast-conserving surgery after NAC.All the patients underwent DWI examination by using both mono-exponential mode and DKI mode before chemotherapy was initiated.The parameters included ADC,mean diffusivity (MD) and mean kurtosis (MK).Within 1 to 3 days before or after MRI examination,the patients underwent aspiration biopsy,received 4 to 8 cycles of NAC and followed by surgery.According to histologic grading before NAC,the patients were classified into well-differentiated and poor-differentiated group.According to the comparison between pathological results acquired from biopsy before NAC and specimen acquired after surgery,the patients were classified into pathologic complete response (pCR) and pathologic non-complete response (non-pCR) according to treatment effect.The imaging parameters were compared between the pCR and the non-pCR group using t test.The predicting ability of two imaging modes was compared and analyzed with ROC analysis.The relationships between multiple imaging parameters,pathologic,clinical characteristics of tumor and treatment effect were analyzed using logistic multi-variate regression analysis,and further analyzed using Wald test.Results There were 30 cases of pCR and 50 cases of non-pCR.The ADC and MD values were lower in the pCR group than in the non-pCR group (P＜0.05).MK value was higher in the pCR group than in the non-pCR group (P＜0.05).ROC analysis showed that the area under ROC curve of ADC,MD and MK in predicting treatment effect were 0.732,0.866 and 0.683 respectively.Logistic regression analysis showed that,according to predicting ability,MD,ADC and MK successively were the independent predictors for the early response to chemotherapy.Conclusion Compared with mono-exponential mode,DKI mode can reflect the real micro-environment and water diffusion restriction within the tumor area more reliably and accurately,and is more suitable to serve as an imaging technique for predicting the response to NAC for locally advanced breast carcinoma.

OBJECTIVETo investigate the possibility and short-term effect of high dose chemotherapy with peripheral blood stem cell support in the preoperative therapy of breast cancer, and-its influence on the following operation and would healing.

METHODSThree patients with T(3)N(1)M(0) (III(a)), T(4)N(1)M(0) (III(b)), T(4)N(1)M(1) (IV) of breast cancer were diagnosed histopathologically. After receiving HDC/APBSCT, the 3 patients were operated on. HDC/APBSCT process included 2 cycles of FEC induction chemotherapy; PBSC mobilization, APBSC collection and cryopreservation and PBSC infusion; and high-dose chemotherapy, APBSC infusion and supportive therapy. The therapy consisted of CTX2.5 g/m(2), VP-16 600 mg/m(2), and cerboplatin 600 mg/m(2) delivered on day 1, APBSC infusion 48 h later, rhG-CSF (150 microg, BID) was administered 4 h after infusion of APBSC until WBC was higher than 10 x 10(9)/L. During HDC/APBSCT, the patients were protected in the air laminar flow room with supportive therapy of antibiotics, anti-virus and anti-fungus drugs. They left the air laminar flow room after their WBC was greater than 2 x 10(9)/L. Case 1 was treated by radical mastectomy, Case 2 by improved radical mastectomy, Case 3 by improved radical mastectomy and transplantation of skin for the large area.

RESULTSRapid recovery of bone marrow function was observed in all 3 patients. Operation was performed 4 weeks after HDC/PBSCT in Cases 1, 2 and 33 days in Case 3. No influence was seen on operative procedure and would healing, especially in Case 3 with a large area of skin transplantation. Two patients with stage III(a) and III(b) have been alive since the treatment for 30 months and the other with stage IV died of brain metastasis 16 months later.

CONCLUSIONSHDC/APBSCT as a preoperative therapy for breast cancer has no influence on the coming surgery and would healing, even on skin transplantation for a large area. It has a practical response in stage III(a) and III(b), but it is still controversial in stage IV. This method as a salvage therapy for patients with breast cancer of intemuediate or stage.
