Objective To discuss the effects of repairing nasal ala defects by free transplantation of autogenous auricle composite tissue flap. Methods 50 cases with nasal ala defects were repaired by free auricular composite tissue flap transplantation from Janu 2003 to May 2013. The defects size was 0.5cm x 0.7cm~1.3cm x 1.5cm. According to the size of the defects, full thick wedge-shaped auricle composite tissue flap were cut off, then inserted into the nasal ala defects area and fixed stablely, the donor sites were sutured directly avoiding ear cartilage. Salvianolate and hyperbaric oxygen were used in postoperative treatment for 5-7 days. Results 48 cases achieved good results, 2 cases had partial necrosis of composite tissue flap after operation, also achieved good results after reoperation. Over 3 months~5 years follow-up, all cases had satisfactory results. The volume of auricle composite tissue flap reduced less than 10%. Surgical incisions had a linear scar, good color matching, nostril symmetry. All patients were satisfied with the overall appearance. Conclusions Autogenous auricle composite tissue flap free transplantation for repairing middle and small size of nasal ala defects can recover ala formation and structure very well, nasal appearance can be improved greatly with nostril symmetry. There is no hypertrophic scar in donor sites. This method is simple and easy,and is also a good method for repairing nasal ala defects.

Objective To study the effects of Panax Notoginseng Saponins (PNS) on the damaged expression of ZO-1 of brain microvascular endothelial cells caused by Aβ42.MethodsBrain microvascular endothelial cells were divided into normal control group, model group, PNS low-, medium- and high concentration groups. They were incubated for 24h in 5% CO2 incubator at 37℃ . Then cell vitality was detected by MTT colorimetric method and ZO-1 protein expression was tested by Western blot.Results Stimulation of Aβ42 reduced the activity of microvascular endothelial cells (P<0.01) and suppressed the expression of ZO-1 protein (P<0.01). Compared with the model group, the activity of microvascular endothelial cells of PNS groups, especially the high and medium dose groups (P<0.05), and increased the ZO-1 protein expression. Conclusion PNS can partly recover the barrier function of blood brain barrier through inhibiting the decrease of the activity of microvascular endothelial cells caused by Aβ42.

Objective To observe the changes of cerebral vascular morphology and blood flow after craniocerebral trauma so as to investigate the role of transcranial Doppler sonography (TCD) combined with CT angiography (CTA) in judgment of the operative effect and prognosis of severe craniocerebral trauma.MethodsA total of 56 patients with craniocerebral trauma were monitored dynamically by using TCD before and after surgery.Dynamic CTA of head was also performed by using 128-slice spiral CT.Results TCD and CTA indicated that both the cerebral blood flow and vascular morphologychanged after craniocerebral trauma.CTA manifested mainly the vascular displacement or angiostegnosis and TCD showed mainly the high-resistance blood flow,indicating good operative effect.For the patients with vasospasm,the TCD manifested high-resistance flow (relatively good operative effect) or nail flow(mostly poor operative effect). The patients with vascular occlusion were associated with nail flow on TCD,with poor operative effect.ConclusionsTCD shows the velocity of cerebral blood flow and CTA shows the morphological change of cerebral vessels.Thereby,the combination of TCD and CTA can effectively judge the cerebral perfusion and provide a promising way for validating the operative effect and prognosis of craniocerebral trauma.

Objective To observe the therapeutic effect of hoop circumference drug,Hongzhongxiao tincture,on the treatment of skin abscess in rats under the guidance of defended field theory.Methods Forty SpragueDawley (SD) rats were randomly divided into normal control group,model group,western medicine control group,Hongzhongxiao pretreatment group and Hongzhongxiao treatment group according to the computer generated random number.Subcutaneous abscesses models were reproduced by subcutaneous injection of 1 mL (3-5 × 109 cfu/mL) of staphylococcus aureus,and the normal control group was subcutaneously injected with the same amount of normal saline.After molding,the rats in the model group were treated with normal saline for change of dressing;the western medicine control group was treated with mupirocin ointment for external use;Hongzhongxiao pretreatment group was treated with 2 mL of Hongzhongxiao for dressing 4 hours after the modeling;in Hongzhongxiao treatment group,2 mL dressing was given after the emergence of hard swelling,and the Hongzhongxiao drug range applied was 1 cm over the swelling range.Each group was dressed once daily.The changes of mental state,body weight,skin temperature,range and time of abscess formation,wound ulceration and healing time,transcutaneous oxygen pressure (TcPO2) at the periphery of abscess were observed in each group.Results ① After modeling,the activity of the rats was decreased,the appetite became worse,and the food intake less.Except the normal control group,the rats in other groups had different degrees of mental listlessness.② After 3 days of treatment,the body weight gain of the model group was significantly lower than that of the normal control group (g:8.75 ± 9.85 vs.31.67 ± 7.92,P ＜ 0.01),and continued to 18 days after treatment (g:27.13± 11.70 vs.98.00 ± 8.94);after treatment for 18 days,the body weight gain in the western medicine control group,Hongzhongxiao pretreatment group and Hongzhongxiao treatment group was significantlyhigher than those of model group (g:53.28 ± 19.69,49.12 ± 7.23,44.71 ± 12.42 vs.27.13 ± 11.70,all P ＜ 0.05).③ After 3 days of treatment,the body temperature of the model group was obviously lower than that of the normal control group (℃:33.75 ± 0.68 vs.35.03 ± 0.41,P ＜ 0.01) and continued to 10 days (℃:34.30 ± 0.35 vs.35.03 ± 0.41,P ＜ 0.01).The body temperature of the rats in Hongzhongxiao pretreatment group was significantly lower than that in the normal control group,the model group and the western medicine control group on the 14th day after treatment (℃:33.97 ± 0.83 vs.35.10 ± 0.57,35.01 ± 0.68,35.25 ± 0.23,all P ＜ 0.05).The body temperature of Hongzhongxiao treatment group was significantly higher than that of the Hongzhongxiao pretreatment group (℃:34.87 ± 0.94 vs.33.97 ± 0.83,P ＜0.05).④ After treatment for 13,15,17 days,the contraction rates of swollen area in western medicine control group,hongzhongxiao pretreatment group and hongzhongxiao treatment group were greater than the rate in model group,and the change was most significant on the 17th day after treatment [(96.37 ± 5.09)％,(92.76 ± 13.56)％,(98.41 ± 3.85)％ vs.(77.46 ± 19.07)％,all P ＜ 0.05].⑤ Compared with the model group,the times of abscess localization in the western medicine control group,the Hongzhongxiao pretreatment group and the Hongzhongxiao treatment group was shorter than that in the model group (days:9.28 ± 1.38,7.33 ± 1.97,7.67 ± 1.63 vs.12.63 ± 1.99,all P ＜ 0.05);the time of wound healing in Hongzhongxiao pretreatment group aud Hongzhongxiao treatment group were significantly shorter than those of the model group (days:17.67 ± 1.03,16.83 ± 1.51 vs.19.92 ± 2.33,P ＜ 0.05).⑥ TcPO2 in the Hongzhongxiao pretreatment group was significantly higher than that in the model group on the 7th day after treatment [mmHg (1 mmHg =0.133 kPa):63.33 ± 9.77 vs.39.51 ± 8.42],and the Hongzhongxiao treatment group (44.25 ± 6.41) was significantly lower than that of the Hongzhongxiao pretreatment group,and the Hongzhongxiao treatment group was significantly higher than that of the model group (59.50 ± 7.34 vs.49.52 ± 10.17) on the 14th day after drug application,and the western medicine control group was significantly lower than that of the model group (37.71 ± 5.63 vs.54.33 ± 7.74),the Hongzhongxiao pretreatment group and Hongzhongxiao treatment group were significantly higher than those of the western medicine control group,the difference being statistically significant (all P ＜ 0.05).Conclusions The Hongzhongxiao tincture applied on top and circumferentially around the periphery of the abscess can reduce the local inflammatory response,improve the body weight and mental state,increase the blood supply around wound periphery for anti-infection and anti-inflammation in order to promote the formation of defending field of nursing.Although the early application of Hongzhongxiao tincture cannot reduce the local infectious symptoms and kill the Staphylococcus aureus,it can make skin abscess localization as soon as possible and shorten the wound healing time.

Objective To investigate the effect of optimizing rescue time for patients with acute st-elevation myocardial infarction (STEMI) in the hospital. Methods A retrospective analysis of the clinical data of 133 patients with ST-elevation myocardial infarction who were hospitalized in the first affiliated hospital of university of science and technology of china during July,2016 to June,2017 was performed. Timeline in the rescue, the result of coronary reperfusion and satisfaction degree of patients were analyzed. Results The rapid evaluation time (F=2.609, P=0.046),emergency handling time(F=7.581, P=0.032), login and logout time (F=5.667, P=0.017)and visit-ballon time (F=8.942, P=0.007) were shortened quarter by quarter . The average time of each project in the four quarters showed a statistically significant difference. The difference of TIMI classification of coronary flow reperfusion among the four quarters was statistically significant (H=8.402, P=0.038). The satisfaction degree of each quarter showed a statistically significant difference (the third quarter of 2016:94.68±2.38, the fourth quarter of 2016:96.72± 5.10, the first quarter of 2017:97.23 ± 7.64,the second quarter of 2017:98.36 ± 4.86;F=7.891,P=0.048). Conclusions Enhancing timeliness of emergency care can remarkably shorten rescue time, improve satisfaction degree of patients and help to improve the success rate of emergency treatment for patients with STEMI.

Objective:To observe the efficacy of free transplantation of latissimus dorsi musculocutaneous flap and anterolateral femoral skin flap in repairing the wound after the resection of the scalp squamous cell carcinoma, and to explore the indications of these two skin flaps.Methods:The clinical data of patients with scalp squamous cell carcinoma admitted to the Plastic Surgery Department of the Second Affiliated Hospital of Kunming Medical University from June 2013 to May 2019 were analyzed retrospectively. All patients showed no cancer metastasis examined with CT. None of the patients had systemic diseases such as hypertension, diabetes, vascular disease. The wounds were repaired with free transplantation of latissimus dorsi myocutaneous flaps and anterolateral thigh flaps after extensive tumor resection. The intraoperative vascular variation, the diameter of the anastomosed blood vessel, the length of the vascular pedicle, the flap size, the time of harvesting the flap, the time for anastomosis, the operation time, and the incidences of complications at the donor site and recipient site were measured or recorded in both groups.Results:A total of 21 cases were included, including 14 males and 7 females, aged from 12 to 61 years. Eleven cases were repaired with the latissimus dorsi musculocutaneous flap, and 10 cases with the anterolateral thigh flap. All the 21 flaps survived during the 1 to 2 years follow-up. No vascular variation was found in the latissimus dorsi myocutaneous flap group, whereas 2 cases of vascular variation were found in the anterolateral thigh flap. In the latissimus dorsi myocutaneous flap group, the anastomotic vessel diameter was (2.14±0.09) mm for the artery and (2.49±0.10) mm for the vein. The vascular pedicle length was (6.14±0.28) cm, and the size of the flap was (135.0±20.8) cm 2, the harvesting time was (114.8±3.0) min, the vascular anastomosis time was (20.8±0.8) min, and the operation time was (6.5±0.2) h. In the anterolateral thigh flap group, the anastomotic vessel diameter was (2.15±0.14) mm for the artery and (2.45±0.15) mm for the vein. The vascular pedicle length was (6.80±0.31) cm, and the size of the flap was (159.9±16.4) cm 2, the harvesting time was (119.8±3.6) min, the vascular anastomosis time was (21.5±0.9) min, and the operation time was (6.9±0.2) h. There was no significant difference between the two kinds of flaps in the above parameter. The incidence of total complications at the donor site was higher in the latissimus dorsi myocutaneous flap group (7 cases) than that in the anterolateral thigh flap group (4 cases). The incidence of overall complications at the recipient was lower in the latissimus dorsi myocutaneous flap group (1 case) than that in the anterolateral thigh flap group (2 cases). Conclusions:Both the latissimus dorsi myocutaneous flap and the anterolateral femoral skin flap can achieve good results in repairing the wound after the resection of the scalp squamous cell carcinoma. The latissimus dorsi myocutaneous flap has a constant blood supply, and the operative technique is relatively easy and with low risk, which is more suitable for novices. The anterolateral thigh flap is thin and with fewer complications at the donor site. It is easy to be accepted by patients and can be performed in the supine position, which is more suitable for elderly patients.

Objective To investigate the clinical effect of free pre-expanded scapular skin flap for repairing of large size facial and cervical scar .Methods 15 patients suffering from post-burn facial and cervical scar contractures were treated in the Department of Plastic Surgery of Second Affiliated Hospital of Kunming Medical University.The reconstruction was performed in two operative stages .First, the skin incision were made paralleling with the descending branches of the circumflex scapular artery near posterior axillary line and the scapular skin flap was elevated .A 300 to 400 ml kidney -shaped expander was implanted under scapular region skin .The expansion began 1 week post-operatively.After the expander was fully expanded and could supply sufficient flap , the facial and cervical scar was resected and the contracture was released .The pre-expanded scapular flap was harvested and transferred to repair the defects.Then the facial vascular anastomosis with circumflex scapular vascular was performed .The expander was removed and the wound was closed directly .Results The expansion time ranged from 2 to 4 months with the average time of 2.8 months.The flap size ranged from 14 cm ×7 cm to 25 cm ×14 cm. All flaps survived post-operatively and wounds at donor sites healed primarily .The face and neck have good appearance .Conclusions Pre-expanded scapular skin flap is suitable for repairing of larger face and neck scar with good color and thickness match .Expanded skin flap can provide large size flap , leaving less morbidity at the donor sites .
