The deoxyribose degradation assay is widely used to evaluate the hydroxyl (.OH) radical-scavenging ability of food or medicines. We compared the hydroxyl radical-scavenging activity of 25 antioxidant samples prepared in ethanol solution with samples prepared after removing the ethanol (residue). The data suggested that there was an approximately 9-fold difference between assay results for the ethanol solution and residue samples. This indicated a strong alcoholic interference. To further study the mechanism, the scavenging activities of 18 organic solvents (including ethanol) were measured by the deoxyribose assay. Most pure organic solvents (especially alcohols) could effectively scavenge hydroxyl radicals. As hydroxyl radicals have extremely high reactivities, they will quickly react with surrounding solvent molecules. This shows that any organic solvent should be completely evaporated before measurement. The proposed method is regarded as a reliable hydroxyl radical-scavenging assay, suitable for all types of antioxidants. © 2013 Elsevier Ltd. All rights reserved.

Open radical inguinal lymphadenectomy is reported to have morbidity as high as 50%. We describe our endoscopic inguinal lymphadenectomy that aims at decreasing the morbidity of the procedure without compromising the oncologic outcomes. Eleven groin dissections were undertaken in seven male patients. The procedure was performed via three ports. The first one was a 10-mm incision 3 mm distal to the apex of the femoral triangle. Two additional trocars (10 mm and 5 mm) were positioned 6 cm medially and laterally to the apex of the triangle, respectively. Taking the great saphenous vein as a landmark, the superficial and deep components were dissected. The boundaries of dissection were the same as those of radical inguinal lymphadenectomy. The numbers of lymph nodes harvested were recorded. The morbidity was retrospectively analyzed. The mean operative time was 126 minutes. The mean number of lymph nodes was 12.3. The averaged output of drainage per leg was 50.8 mL each day. There were only three minor complications: One patient had hypercarbia and pneumoderm, and another had 50 mL of seroma; the third had 180 mL of lymphocele. Follow-up ranged from 4 to 27 months (mean 16.3); there was no evidence of recurrence and other sequelae. Endoscopic inguinal lymphadenectomy is feasible for patients with penile cancer and genital malignancy. The technique reduces the risk of complication rate, and the oncologic outcome is highly promising. Larger studies, longer term follow-up are needed to assess the oncologic control and possible morbidity.

The original pyrogallol (1,2,3-trihydroxybenzene) method, which was developed specifically for superoxide dismutase, is now widely used for measuring superoxide-scavenging of other antioxidants. However, the strong pH effect has been ignored. In this study, the influencing factors have been systematically investigated for the first time, and a number of experiments have proved that the pH is of major importance. As major antioxidants contain carboxylic acid, ester, or lactone groups, pH 8.2 should be modified to physiological pH 7.4. The improved procedure is as follows. A pyrogallol solution (in 1 M HCl) is thoroughly mixed with pH 7.4 Tris-HCl buffer; A 325 nm is measured every 30 s for 5 min at 37 °C. As the ΔA325 nm, control value reflects the initial concentration of substrate •O2 -, it should be well controlled to guarantee the accuracy of the method. The improved pyrogallol method is a reliable and cheap superoxide-scavenging assay suitable for all types of antioxidants. © 2012 American Chemical Society.

Purpose: The purpose of this study was to compare the outcomes following the posterior or anterior approach of Kugel repair for the surgical treatment of inguinal hernias. Methods: Patients with inguinal hernias who were treated using the original posterior approach (P group, n: 1262) and the anterior approach (A group, n: 1119) in China between 2003 and 2008 were evaluated retrospectively. The operation time, hospital stay, postoperative complications and recurrence after surgery were assessed and compared statistically in both groups. Results: The age, gender, types of hernia, operation time, hospital stay and the follow-up were comparable in the two groups. The operation time was 44.16 ± 12.66 min in the P group and 49.45 ± 14.34 min in the A group (P > 0.05). There were no significant differences in the incidence of hematoma, seroma and urinary retention, but the rate of incisional infection and severe pain in the A group were significantly lower than that in the P group (P < 0.05). The rate of recurrence differed significantly between the two groups with eleven in the P group (0.87 %) and one in the A group (0.09 %) (P < 0.05). Conclusion: The lower rate of incisional infection, severe pain after surgery and much lower recurrence show the superiority of the anterior approach in comparison to the posterior approach for a Kugel repair of inguinal hernias. © 2012 Springer.

The objective of this study was to determine whether topical tranexamic acid (TXA) carried similar hemostatic effect compared with intravenous TXA in total hip arthroplasty (THA). Three hundred and three THA patients were enrolled and randomized into 3 groups: no TXA group, topical and intravenous TXA group. The results showed that the topical and intravenous TXA group had reduced but similar blood transfusion rates (5.88% v. s. 5.94%, P = 0.816). No significant difference was detected in total blood loss between the two TXA groups [(963.4 ± 421.3) ml vs. (958.5 ± 422) ml P = 0.733]. We conclude that topical use of TXA was equally effective and safe compared with intravenous TXA in reducing blood loss and transfusion rate following THA without substantial complications. © 2014 Elsevier Inc.

To investigate the clinical application and early results of combined epiphyseal preservation. Between March 2010 and March 2011, and autograft bone transfer for limb salvage in children with osteosarcoma. 3 children with osteosarcoma were treated with epiphyseal preservation and autograft bone transfer. There were 1 boy and 2 girls with the age of 10-14 years. The disease duration was 2 weeks to 3 months. The tumors were rated as type II according to San-Julian radiological classification and as type IIB according to Enneking surgical classification. The locations were the distal femur in 1 case and the proximal tibia in 2 cases. The surgical technique included preoperative neoadjuvant chemotherapy, excision of part of the epiphysis, preservation of subarticular epi physis, external fixation with Ilizarov apparatus and transport osteogenesis treatment. Safe excision border was confirmed by histological examination. Postoperative observation included the wound healing, local recurrence or distant metastasis, length, speed, alignment, and regeneration of transplanted bone, the length and function of the affected limb. The postoperative histological examination proved the safe surgical margin in all 3 patients. The incision healing by first intention was obtained at distal femur in 1 case and by second intention at proximal tibia in 2 cases at 4 weeks after changes of dressing. Three patients were followed up 12, 18, and 24 months, respectively. There was no local recurrence or distant metastasis during follow-up. Two cases had pin-tract infection at 10 months after external fixation and were cured after changes of dressing and antibiotics administration. The length of transplanted osteogenisis was 18.0, 9.5, and 16.0 cm, respectively. The speed of lengthening was 2.57, 2.07, and 1.20 cm/month, respectively. One patient had alignment deviation during lengthening, which was adjusted under anaesthesia. Bony healing was achieved at 8 months after lengthening end in 2 cases and external fixation was removed; 1 patient had poor bone growth and was given retraction for promoting bone growth. At last follow-up, the length of the affected limbs was 1.0-1.5 cm shorter than that of normal limbs, but no abnormalities was observed at donor sites. The affected knee flexion reached 90 degrees and 120 degrees in 2 patients and poor knee function was observed in 1 patient for external fixation. The combined epiphyseal preservation and transport osteogenesis technique can be used for bone defect repair by lengthening the residual bone. It is a promising limb salvage treatment for children with osteosarcoma.

To isolate and identify active neuraminidase constituents of Polygonum cuspidatum against influenza A (H1N1) influenza virus. On the basis of the bioassay-guided fractionation,such chromatographic methods as silica gel, sephadex LH-20 and HPLC were adopted to isolate active constituents of extracts from Polygonum cuspidatum, and their molecular structures were identifiied on the basis of their spectral data such as NMR and MS and physico-chemical properties. Seven compounds were isolated from the ethyl acetate extract of P. cuspidatum and identified as 2-methoxystypandrone (1), emodin (2), resveratrol (3), polydatin (4), emodin-8-O-beta-D-glucopyranoside (5), (E)-3, 5, 12-trihydroxystilbene-3-O-beta-D-glucopyranoside-2'-(3", 4", 5"-trihydroxybenzoate) (6) and catechin-3-O-gallate (7), respectively. Among them, the NA test showed that compounds 3, 6 and 7 had inhibitory effect against NAs activity, with IC50 values of 129.8, 44.8 and 21.3 micromol x L(-1), respectively. Moreover, the further CPE test showed compounds 6 and 7 had significant inhibitory effect against H1N influenza virus (EC50 = 5.9, 0.9 micromol x L(-1), respectively), with very low cytotoxicity to the host cells, their therapeutic selective index(SI) in MDCK cells ranged from 56 to 269. The neuraminidase inhibitors against H1N1 anti-influenza virus isolated from extracts of P. cuspidatum on the basis of the bioassay-guided fractionation are significant in specifying their therapeutic material basis and drug R&D against influenza.

A new study confirms these results and patients three month follow up appointments continue to be significantly intact. Three months later, the success rate remained remarkably at 89%, demonstrating that acupuncture and moxibustion provides both short term and long term benefits for depressive patients. Depression affects over 15 million adults in the US, roughly 6.7% of our population. This research brings hope to this severe, yet common illness. Dana Point, CA, February 28, 2017 --( Dr. Kathleen Albertson, a licensed acupuncturist, and herbalist remarks, “This study encourages those patients with depression to seek acupuncture therapy in conjunction with their western protocols. It not only opens the door for the patient to improve his/her quality of life, but may lead the way to a decrease in the patients’ need or use of Western pharmaceutical drugs which have severe side effects.” “It is not our place, nor is it legal, for an acupuncturist to recommend that a patient change any use or dosage of medications prescribed by a Western MD; but often the patient and their doctor reach solutions that may benefit that patient.” She further remarks, “Psychologists and therapists have a long history of acknowledgement and support for recommending acupuncture to their patients for not only depression, but stress, postpartum, and anxiety, as well.” Acupuncture releases endorphins and calms the nervous system, allowing the body and mind to reach homeostasis (balance). It is proven to reduce pain and support our physical and emotional systems, and has been utilized for over 5000 years. “It is never too late to research new options that can help you,” she reports.
