ABSTRACT
Objective To discuss the clinical effect of facial contour remodeling using transplantation of the autologous granular fat grafting combined with botulinum toxin A injection.Methods Negative-pressure liposuction was carried out in the inner thigh or abdomen using liposuction needle connected with an injector,to let stand for layered,discharge lower layer water,rinse,extract the fat particles into a 2 ml syringe,inject into facial depression area with multipoint,multiple-tunnel,and multilayer manner,over injection of about 20％-30％ every time.89 patients received the injection;some accepted two injections;13 cases were injected in temple (14.6％),and 16 in forehead (17.98％).30 of them received subcutaneous injection of botulinum toxin A,each side dose was less than 20 U.Results Patients had been followed up for 3-36 months,and obvious improvements were observed in facial contour in the frontal and temporal region as well as the skin texture;the survival rate of fat granule reached to 60％-80％.No hematoma,nodes and infection been observed.Patients combined with botulinum toxin A injection had more ideal facial contour and more satisfaction.Conclusions Autologous fat granules transplantation in the face has stable clinical effect,and combining with botulinum toxin A injection can improve facial contour.It is a safe,ideal treatment in facial rejuvenation and facial contour remodeling and it therefore can be widely recommended in clinical treatment.
ABSTRACT
Objective To evaluate the influence of orthokeratology lenses on vision,intraocular pressure and biometric measurement parameters in adolescent myopia.Methods A total of 72 adolescent myopia patients (136 eyes) with orthokeratology lens,aged 8-16 years old,in Hebei Provincial Eye Hospital from Junuary 2013 to December 2015 were randomly selected.The vision,intraocular pressure,axial length,corneal topography,corneal thickness and anterior chamber depth were observed before wearing glasses,at 1 week,1,3,6 months after wearing glasses.Results After orthokeratology wearing,the uncorrected visual acuity was obviously improved (P＜0.05),the average refraction diopter was declined (P＞0.05) and the non-contact intraocular pressure was decreased (P＜0.05).The axial length after orthokeratology wearing had little change (P＞0.05).The curvature of the patient's cornea at one week after wearing glasses was deceased (P＜0.05) and the posterior corneal curvature tended towards stability.The corneal thickness at 1 week after wearing glasses had no obvious change compared with before wearing glasses(P＞0.05),which at 1 month after wearing glasses was decreased(P＜0.05) and which at 3,6 months after wearing glasses trended to be stabilized.The anterior chamber depth after wearing glasses had no obvious change.Conclusion Orthkeratology lens can decrease the myopia degree,increases the uncorrected visual acuity and has obvious effect for controlling adolescent myopia.The intraocular pressure and biometric measurement parameters have corresponding change after wearing orthkeratology lens.
ABSTRACT
Objective The diabetic foot ulcer has high incidence rate,many complications,and is difficult to heal.Methods We summary the treatment expericncc of 156 cases of diabetic foot wounds.On the basis of comprehensive standard medical treatment,according to the wound characteristics,blood supply,and the degree of tissue necrosis,we performed staging gnawing-away debridement for all tbe wounds,combining with pressure suction,new dressing,skin grafts and skin flaps.Results Of all the 156 cases,2 cases died,4 cases were lost to follow-up,the remaining 150 cases healed,with an average time of 56 days.Conclusions The treatment of diabetic foot ulcer must take into account both the systemic therapy and local processing,the wound should be debrided with different stage and progressively.When the wound microenvironment is gradually improved,it can be covered appropriately with skin grafts.The skin flap should be chosen cautiously.
ABSTRACT
Objective To explore the long-term efficacy of botulinum toxin type A injections on facial beauty and its long-term safety.Methods A total of 33 beauty-seekers with botulinum toxin type A treatment for more than five years were reviewed as observation group,using digital muscle palpation meter (Myoton PRO) for the determination of the orbicularis oculi muscle and masseter muscle tension (F),the muscle characteristic parameters,such as muscle hardness (S) using a homemade facial questionnaire test for satisfactory rate of beauty from both beauty-seekers and physicians.At sametime,33 normal adults that never accepted botulinum toxin injection with matched age and gender were collected as control group.The same-sex indicators were dtermined and compared with using statistic analysis t test.Results The pairwised parameters of the same sex and site were comparied between the two groups;average F and S values in the observation group were lower than those of the control group,but no statistically significant difference were observed between the two groups (P＞0.05);in the observation group,average appearance age was 7.3 years younger than the control group,and the facial shape improved significantly.Conclusions Long-term and repeated application of botulinum toxin A is able to remove crow's feet and decrease the masseter and so the injection is safe with high satisfaction to beauty-seekers.
ABSTRACT
ObjectiveTo observe the clinical efficacy of acupuncture at cranial sutures (cranial acupuncture) plus rehabilitation training in treating cerebral infarction.MethodSixty patients with cerebral infarction were randomized into an acupuncture-rehabilitation group (cranial acupuncture plus rehabilitation training) and a rehabilitation group (dryrehabilitation training), 30 cases in each group, to respectively receive cranial acupuncture plus rehabilitation training and dry rehabilitation training. The Fugl-Meyer Assessment (FMA) and Barthel Index (BI) were adopted to respectively evaluate the motor function of limbs and activities of daily living (ADL); the content of hypersensitive C-reactive protein (hs-CRP) was also observed before and after treatment for the evaluation of therapeutic efficacy.ResultThe acupuncture-rehabilitation group wassuperior to the rehabilitation group in improving the motor function and ADL, and down-regulating the hs-CRP content (P<0.05).ConclusionCranial acupuncture plus rehabilitation training is the optimal protocol in treating cerebral infarction, and it canproduce a more significant efficacy than dry rehabilitation training.
ABSTRACT
Objective To investigate the effect of expanded deltopectoral perforator flap as a free skin flap for distant transfer to aesthetically repair large facial scars via microsurgical technique.Methods 20 cases of large facial scars were treated with free expanded deltopectoral skin flaps via microsurgical technique.At the first stage,24 large volume expanders were inserted into the subcutaneous pockets in the deltopectoral zone.4 to 6 months later,the second stage operation was performed when the flaps were expanded fully and facial scars removed;deltopectoral perforator flaps harvested choosing the second or the third thoracic artery perforating branches as the pedicle;the surface of the wound was covered with the flaps.Results All of the 24 flaps survived completely and the wounds healed well after transplantation.The 6 months to 2 years' follow-up results showed that the color and texture of the flaps matched the recipient place well without swelling.The superficial and deep sensation recovered very fast.Conclusions It is safe,practical and effective that the delto-pectoral perforator flaps are used to repair large facial scars avoiding the shortcomings of traditional pedicle transfer such as more procedures,longer fixed time,or more wasted expanded skin.Free transfer of expanded delto-pectoral perforator flaps can achieve ideal function and aesthetic effects.
ABSTRACT
Objective To investigate the preventive effect of thin foam dressings(Allevyn Thin)combined with ice compress on facial plastic postoperative swelling and to summarize the nursing key points.Methods Sixty patients after facial plastic surgeries in our department were randomly divided into the observation group and the control group with 30 cases in each group.In the control group,ice packs wrapped with sterile gauze were placed on the patients’ wound dressings postoperatively and fixed properly for 30 to 40 minutes with an interval of 30 minutes,6 to 10 times a day for 72 hours postoperatively.In the observation group,thin foam dressing was stick to the wounds,followed by ice compress as in the control group.The facial swelling degrees of both groups were compared on day 3 and day 7 postoperatively.Result The swelling degree in the observation group was significantly smaller than that of the control group(P<0.01).Conclusion Thin foam dressings combined with ice compress can effectively improve the postoperative early swelling of patients receiving facial plastic surgery and therefore it is worthy of clinical popularization and application.
ABSTRACT
Objective To explore the biological effects of estrogen (17β-E2) on the proliferation and migration of human skin fibroblast (HSFB).Methods HSFBs were isolated and cultured by enzyme digestion.The fourth generation of HSFBs were adopted; (1) the proliferating effect of diverse concentrations of 17β-E2 and 17β-E2+ ICI-182780 on HSFBs was determined with MTT method at 24,48,72,96 h; (2) the influence of 17β-E2 and ICI-182780 to HSFBs cycle distribution were determined with flow cytometry; (3) the migration effect of diverse concentrations of 17β-E2 and 17β-E2+ICI-182780 on HSFBs was determined at 24,48,and 72 hours after the creation of the scratch-wound in vitro.Results (1) The proliferating speed of HSFBs in 10-10mol/L 17β-E2 group (group A)was the highest of all at 48,72,96 h,which was higher than that in ICI-182780+10-10mol/L 17β-E2 group (group B) and control group (group C) (P＜0.01) ;(2) the HSFBs during the S phase in group A was more than that in groups B and C (P＜0.01),while the HSFBs during the G0/G1 phase was less than that in groups B and C (P＜0.01); (3) the migrating effect of HSFBs in 10-8mol/L 17β-E2 group (group D) was the highest of all at 48 h,which was higher than that in ICI-182780+10-10mol/L control group (group E)and control group (group F) (P＜0.01).Conclusions The concentration of 10-10mol/L estrogen has the strongest effect of promoting proliferation and that of 10-8mol/L has the strongest chemotaxis; ICI-182780 can abate the above effect effectively.
ABSTRACT
Objective To explore the possible pathway and regulatory mechanism of dermal fibroblasts' transdifferentiation into myofibroblasts induced by estrogen. Methods Human dermal fibroblasts were divided into six groups (A: control; B: estrogen; C: estrogen + ICI-182780; D: estrogen + SB203580; E: estrogen + PD98059; F: estrogen + SP600125). The cells were collected for RNA extraction and the expression of α-SMA was detected by real time quantitative RT-PCR. Some cells were analyzed by single cell RT-PCR to detect positive expression percentage of α-SMA.Results The expression and positive rate of α-SMA in estrogen group were significantly increased (Group B vs. Group A, 7. 385±0. 246 vs 1. 367±0. 034, P＜0.01) and those in ICI-182780 group and SP600125 group were significantly inhibited (Groups C and F vs. Group B, 4. 619 ±0. 164,2. 409±0. 091 vs 7. 385±0. 246, P＜0. 05). Conclusions In the process of fibroblast transdifferentiation into myofibroblasts induced by estrogen, estrogen β receptor and JNK-MAPK signal transduction pathway may play an important role.
