Objective To investigate the therapeutic effects of botulinum toxin type A injection and acupuncture on periorbital wrinkles.Methods From May to September in 2015,24 patents were randomly divided into experimental and control group according to random number table:the patients in experimental group were treated with disposable acupuncture needles,20 min for each treatment,once a day,five times each course for courses,2 days interval between the two courses;the patients in control group were treated with 20 units of hotulinum toxin type A injection.The therapeutic results were observed 2 weeks after the treatment by the third-party doctor according to skin wrinkles grading.Results The periorbital wrinkles in both groups improved remarkably,and the wrinkle grading in control group was significantly lower than that in the experimental group (0.67±0.67 vs 1.33±0.61,P＜0.05).The skin quality and facial expression sensation in the experimental group improved significantly when compared with those in the control group.Conclusions Acupuncture can be used as a complementary treatment of periorbital wrinkles,and it improves the skin quality in terms of elasticity and color and keeps the natural facial expression sensation.

BACKGROUND:Among the factors causing vascular endothelial cell injury,angiotensin Ⅱ(Ang Ⅱ) caused by renin-angiotensin system (RAS), especially by local RAS, plays an important patho-physiological role.OBJECTIVE: To observe the effect of tanshinone ⅡA on the vascular endothelial cells secreting nitric oxide (NO) and endothelial nitric oxide synthase (eNOS) gene expression as well as intracellular Ca2+ level induced by Ang Ⅱ, and investigate the protective effect of tanshinone ⅡA on vascular endothelial cells.DESIGN: Controlled observation experiment.SETTING: Department of Emergency, Tongji Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology.MATERIALS: This experiment was carried out in the Experimental Center for Basic Medicine, Tongji Medical College,Huazhong University of Science and Technology from March 2006 to October 2006. Porcine aorta used in this experiment was provided by the Department of Pathophysiology of Tongji Medical College.METHODS: Nitric acid deoxidization method and reverse transcription-polymerase chain reaction (RT-PCR) were used to detect the effects of Ang Ⅱ of different concentrations (10-8 to 10-6 mol/L) on endothelial cells secreting NO and eNOS mRNA expression in cultured porcine aortic endothelial cells at different time points (1,6 and 24 hours) separately, then 50 mg/L tanshinone Ⅱ A was respectively added at different time point (0, 6 hours) when Ang Ⅱ was at 10-6 mol/L, and changes in NO production and eNOS gene expression were detected respectively at 1, 6 and 24 hours. Intracellular Ca2+ level was also detected with laser scanning confocal microscopy.MAIN OUTCOME MEASURES: ① NO content. ②eNOS mRNA expression. ③Intracellular Ca2+ level.RESULTS: ① NO production and eNOS mRNA expression were decreased with increase of Ang Ⅱ concentration and prolongation of time (P ＜ 0.01). ② NO production and eNOS mRNA expression in each tanshinone ⅡA-treated group were significantly higher than those in the Ang Ⅱ group. At 1 and 6 hours of tanshinone ⅡA treatment, production of NO and eNOS mRNA expression in the Ang Ⅱ + tanshinone ⅡA group were significantly higher than those in the Ang Ⅱ 6 hours + tanshinone ⅡA group (P ＜ 0.05); There were no significant differences in NO production and eNOS mRNA expression between two groups at 24 hours (P ＞ 0.05). ③Intracellular Ca2+ level in the Ang Ⅱ group was significantly higher than that of control group (P ＜ 0.01), and intracellular Ca2+ level in the tanshinone ⅡA + Ang Ⅱ was significantly lower than that in the Ang Ⅱ group (P ＜ 0.05).CONCLUSION: Tanshinone Ⅱ A has a protective effect on vascular endothelial cells and their functions by suppressing the inhibition of Ang Ⅱ on NO level and eNOS gene expression in cultured porcine aortic endothelial cells.

Objective To correct the high supratarsal fold after cosmetic upper blepharoplasty is a challenge because of the shortage of both upper eyelid skin and fat.Levator shortening has been a procedure of choice selected by the surgeons to correct this condition.Methods Under local anesthesia, the desired crease was marked according to the characteristics of eyelid anatomy and aesthetic consideration for Asian women.The incision was made through the marked new skin crease and the old incision with surrounding scar tissue was incised.The adhesion between the skin and the levator aponeurosis was completely released.The levator aponeurosis was then divided above the tarsal plate.It could be shortened and then reattached to the tarsal plate depending on the amount of the upper eyelid skin and the degree of the ptosis.The skin incision was then closed to form new but lowered fold.Results Between 2003 to 2015, a total of 34 Chinese women underwent bilateral levator shortening for correction of high supratarsal fold after previous unsatisfactory upper blepharoplasty by other surgeons.There were no surgical complications postoperatively in this series and 32 patients (94.1%) were satisfactory for the outcome of the proper height of the supratarsal fold with at least 1 month follow-up.Only one patient (2.9%) required surgical revision for asymmetry of supratarsal folds and one patient (2.9%) for correction of deepened supratarsal fold.Conclusions The levator shortening can be an effective procedure to correct high supratarsal fold after unsatisfactory upper blepharoplasty in Asian women.It is especially useful to correct such a condition where there is shortage of the eyelid skin combined with the eyelid ptosis.

Objective To evaluate the role of CT in diagnosis of the gastrointestinal tract rupture after blunt abdominal trauma . Methods Twenty preoperative CT scans and clini cal data were obtained in 20 patients who subsequently had bowel ruptures verifi ed surgically. CT findings were analyzed retrospectively in these patients. Retr ospective interpretation was made by consensus of at least two radiologists. Results Twenty cases of CT scan showed intraper itoneal fluid (18 cases), pneumoperitoneum (18 cases), extravasations of gastro intestinal tract contents (2 cases), bowel wall findings (14 cases) and mesenter ic injury (15 cases). Conclusion CT is fast, sensitive and noninvasi ve in diagnosis of the gastrointestinal tract rupture after blunt abdominal tra uma.

Objective To evaluate the efficacy and safety of dorsal root entry zone (DREZ) incision for pain induced by brachial plexus injury. Methods A cohort study was performed in 41 consecutive patients with pain induced by brachial plexus injury treated with DREZ incision from July 2005 to December 2007. Of all, 19 patients were amputated and had phantom limb sensation. Oral pain relief (0%-100%) and complications were followed up by one professional doctor. Oral pain relief rate ≥50% was considered satisfactory outcome. Results The proportion of patients with satisfactory pain relief was 90% (37/41), 81% (30/37), 77% (24/31) and 70% (16/23) at 2 weeks, 3 months, 6 months and last follow-up (over one year) after surgery. At last follow-up, 15 out of 16 patients with over 10 years of pain duration got satisfactory pain relief; while only 16 out of 25 patients with less than 10 years of pain duration got satisfactory pain relief (x2 =4.682, P =0.030). In 16 amputees who were followed up for more than three months, seven patients with alteration of phantom limb sensation got satisfactory pain relief, while only four out of nine patients without alteration of phantom limb sensation got satisfactory pain relief. Among 37 patients followed up for more than three months, severe neurological defects were found in three patients including one with mild motor disturbance in the ipsilateral lower limb and two with severe sensory disturbance in the ipsilateral lower limb. Conclusions DREZ incisions are effective and safe neurosurgical procedure for relieving pain induced by brachial plexus injury. The possible predictive factors of better outcome are the long preoperative pain duration and postoperative phantom limb sensation among amputees.

Objective:This paper aims to bioinformatically analyze the target genes of miR-29b and to provide clues for cancer research targeting miR-29b. Methods:The differential expression levels of miRNAs in CD133+and CD133-A549 cells were detected using the miRNA PCR chip. Real-time polymerase chain reaction was performed to verify the partially differential expression of miR-NAs. Target genes of miR-29b were predicted by miRecords and analyzed by gene ontology and signal transduction pathway enrich-ment analysis. Results: The miR-29b expression was significantly decreased in the CD133+A549 cells compared with that in the CD133-cells. The number of miR-29b target genes was 106. The functions of these target genes were enriched in binding and extracel-lular matrix structural constituent (P<0.01). The JAK-STAT and TGF-βsignal transduction pathways were significantly enriched (P<0.05). Conclusion:The abnormal expression of miR-29b may be related to metastasis. Some of the predicted target genes of miR-29b were significantly enriched in the signaling pathways in relation to the tumors.
