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.

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.

A high performance liquid chromatography method based on amino column to uncover the glycosyls of aroma glycosides in Meili grape was established.Meili grapes were sampled from Yangling, Shaanxi province, China.Aroma glycosides in grape skins were extracted by extraction buffer (0.1 mol/L Na2HPO4/NaH2PO4, pH 7.0, 13% ethanol (V/V)), then enzymatically hydrolysed by AR2000 enzyme preparation in citrate-phosphate buffer (pH 5.0), and the glycosyls liberated were isolated by amino column, and determined by high performance liquid chromatography-refractive index detector (HPLC-RID).The HPLC-RID experimental conditions were developed as follows: amino column temperature 35℃, RID temperature 35℃, injection volume 20 μL, mobile phase acetonitrile/ethyl acetate/water=60∶25∶15 (V/V), flow rate 1 mL/min.The results showed that the reasonable linearity was achieved for rhamnose, xylose, arabinose, apiose and glucose (R2>0.996), with the detection limit (LOD) of 93-123 mg/L and quantitation limit (LOQ) of 309-409 mg/L.The relative standard deviation (RSD, n=10) of the peaks of each monosaccharide (5 g/L) was 2.3%-6.4%, and the recoveries ranged from 73.8% to 125.7%.The molar percentages of the aroma glycosides in Meili grape were 4.1%-6.1% for 6-O-α-L-rhamnopyranosyl-β-D-glucopyranoside, 2.3%-8.8% for 6-O-β-D-xylopyranosyl-β-D-glucopyranoside, 0.1%-3.9% for 6-O-α-L-arabinofuranosyl-β-D-glucopyranoside, 5.5%-9.8% for 6-O-α-L-apiofuranosyl-β-D-glucopyranoside, and 76.3%-86.8% for 6-O-β-D-glucopyranosyl-β-D-glucopyranoside.The contents of each aroma glycoside and the total glycosides in Meili grape didn′t show obvious relationship with berry maturity index during grape maturity.

BACKGROUND: Effect of acellular surfactant and biological safety of bone graft materials highly correlated with selection of surfactant; therefore, a novel compound surfactant was used to prepare acellular bone graft materials in this study. OBJECTIVE: To evaluate acellular effect and biological safety of bio-derived bone tissue treated by a novel surfactant in order to obtain a safe and reliable bone graft material. METHODS: Surfactant was prepared with anionic surfactant sodium dodecyl benzene sulfonate (ABS), anionic surfactant sodium fatty alcohol ether sulfate (AES) and distilled water at the ratio of 13:7:80. Fresh bovine cancellous bone and surfactant which was used to remove cells and lipid by two-step flow were used to prepare a novel bio-derived bone graft material. The histological and microscopic observations of microstructure were made. Also acute body toxicity test, hematolysis experiment, cell toxicity test and biological safety were assessed on surfactant-treated bio-dedved bone graft material (STBB). A long-term animal experiment was conducted to observe the biocompatibility and biodegradability of STBB. The ultraviolet dispersion of light luminosity method was employed to measure the residual amount of surfactant in STBB. RESULTS AND CONCLUSION: STBB was a whitish porous cancellous bone. No cell was found in bone lacuna, bone canaliculus was empty, and the collagen fiber had an order arrangement. Acute body toxicity test was qualified according to GB/116886.11-1997 standard, hematolysis experiment was < 5%, and cell toxicity test was grade 0, confirming that STBB was safe. The remaining surfactant in STBB was lower than 0.1 g/L. The long-term animal experiment demonstrated that fiber was present at 4 weeks, bone lacuna had cellular growth and the fusion of STBB and host appeared. The STBB was partial absorbed by organism at 8 weeks and completely absorbed at 24 hours. The results indicated that STBB had an excellent biocompatibility and biodegradability. As a new bone implant material, STBB was safe and dependable for transplantation.
