ABSTRACT
Objective:To evaluate the efficacy of monopolar radiofrequency combined with ultrasound for abdominal obesity.Methods:A total of 24 patients (4 males, 20 females, average age was 35 years) were given monopolar radiofrequency combined with ultrasound treatment four times at (10±4) day interval at Beijing Friendship Hospital during December 2015 to December 2016. Body weight and abdomen circumferences were recorded before and after each treatment. Subcutaneous adipose tissue thickness was measured with B ultrasound at baseline and after the last treatment. 2 months after the last treatment, a third party would assess the improvement; at the same time, volunteers would assess the outcome with Global Aesthetic International Scale. Blood lipid level, liver function and renal function were tested at baseline and after the third treatment. All the treatment related adverse effect would be noted as well.Results:There was no significant difference of body weight after the treatment. The abdomen circumferences were decreased at 2 month after the last treatment, especially for the navel one, which decreased from (96.14±11.92) cm at baseline to (93.82±10.77) cm, t=4.21, P<0.05. And the subcutaneous adipose tissue thickness also decreased from (25.56±4.3) mm to (24.31±3.77) mm, ( t=6.26, P<0.05). 2 months after the last treatment, 16 volunteers were graded as 1-25% improvement, 8 volunteers were graded as 26%-50% improvement. According to GAIS, 2, 18 and 4 volunteers assess the outcome was regarded as 0 score, 1 score and 2 score respectively. The treatments showed no influence to blood lipid level, liver function and renal function. The treatment processing was tolerated well and no side effect were noted. Conclusions:Monopolar radiofrequency combined with ultrasound treatment for abdominal obesity is effective and safe.
ABSTRACT
Objective To compare the difference of ultrasound-guided anterior sciatic nerve block by multiple injection and single injection.Methods Among 90 patients undergoing lower limb operation,aged 18-68 years old,47 patients were males and 43 patients were females,all falling into ASA Ⅰ-Ⅲ.The patients were randomized to ultrasound-guided anterior sciatic nerve block by multiple injection (group M,n=45) single injection (group S,n=45).Local anesthetic of 0.5% ropivacaine hydrochloride 20 ml was used.The width,thickness and depth of sciatic nerve and blocking performance time were recorded.Sensory and motor blockade on the operated limb were evaluated every 10 minutes after injection of local anesthetic for 30 minutes and complications were observed in two groups.Results The width,thinkness and depth of sciatic nerve on the ultrasound screen were not statistically significant in the two groups.The performance time of group M was longer than that of group S (P<0.05).The proportion of patients with sensory blockade of each nerve significantly differed between the two groups: for superficial peroneal nerve at 10,20,and 30 minutes,for the sural nerve at 20,30 minutes,for the tibial nerve at 30 minutes,that of group M was higher than that of group S (P<0.05).A significantly greater rate of motor blockade was observed for the dorsal flexion of foot and toes extension in group M than that of group S at 30 minutes (P<0.05).The complications of nausea,vomitting and tinnitus were not different in two groups.Conclusion Multiple injection needs more operation time compared with single injection,but its onset time of sensory and motor blockade is quicker,the complications were not different.
ABSTRACT
Objective To evaluate the efficacy and safety of low?level laser therapy(LLLT)for androgenetic alopecia, and to compare the therapeutic effect of LLLT alone versus in combination with finasteride tablets. Methods Thirty?nine male patients were randomly divided into the LLLT group(n=21)and combination group(n=18)to be treated with LLLT alone or in combination with oral finasteride tablets(1 mg/d)for 6 months. LLLT was given twice a week, and each session lasted 30 minutes. All the patients were photographed and asked to fill a questionnaire about subjective symptoms, and hair density (the number of hairs per unit area on the scalp) was determined by using a dermatoscope to evaluate the grade of alopecia, before the treatment, and 3 and 6 months after the treatment. Results The hair density in the LLLT group was significantly higher after 6 months than after 3 months of treatment and before the treatment(184.59 ± 21.17 vs. 169.24 ± 29.21 and 166.67 ± 32.94 hairs/cm2, both P 0.05). The hair density in the combination group significantly increased after 6 and 3 months of treatment compared with that before the treatment(201.80 ± 16.55 and 186.39 ± 17.97 vs. 157.85 ± 27.97 hairs/cm2, both P 0.05), but the combination group showed increased hair density compared with the LLLT group after 3 and 6 months of treatment(both P 0.05). During the treatment, 24(62%)patients felt less greasy, and 22(56%)reported less hair loss, with no discomforts reported by the patients except local warm feeling. Conclusion LLLT is indeed effective for the treatment of androgenetic alopecia with no adverse reactions.

ABSTRACT
OBJECTIVE To investigate the use of a chlorine dioxide-based dental unit waterline(DUWL) treatment to reduce the colonization and growth of heterotrophic bacteria.METHODS Twenty-two dental units with self-contained water systems were randomly selected.Three of the units and tap water served as controls.Twenty-three water samples were taken at baseline and once a week for five weeks.They were serially diluted,spread-plated in duplicate onto R2A agar plates and incubated at 37 ℃ for 7 days.RESULTS At baseline,the 3 control DUWLs had a median count of 8440 colony-forming units/milliliter(CFU/ml) and the 19 treated DUWLs had a median count of 9160 CFU/ml.By week 1,18 of the 19 treated DUWLs had counts of less than 200 CFU/ml,and by week 4,the median count for all of the treated DUWLs was 0 CFU/ml.The measurement at week 5 showed that the reduction to below 200 CFU/ml had been maintained.Scanning electron examination revealed a similar results,with biofilm accumulation more evident in the untreated control specimens.CONCLUSIONS Using a chlorine dioxide-based disinfectant in DUWLs can achieve the American Dental Association(ADA) goal of less than 200 CFU/ml of heterotrophic bacteria per milliliter of unfiltered output water.
ABSTRACT
BACKGROUND:In 2003,a new family of interferon(IFN) III is discovered,that is,IFN-?s including three subtypes:IFN-?1,2 and 3.OBJECTIVE:To analyze the recombinant human interferon-?1(rhIFN-?1) expressed in Pichia pastoris,further more,to identify its physical and chemical characteristics,expression of receptors,and anti-tumor activities.DESIGN,TIME AND SETTING:The single sample observation was performed at the Department of Biochemistry and Molecular Biology,Institute of Basic Medical Sciences from September 2006 to July 2008.MATERIALS:The barms pAO815-4?F-IFN?1/GS115 contained rhIFN?1 expressive plasmids,human cervical carcinoma cell Hela and HCT116 cells were preserved in the state key lab for Molecular Biology from Institute of Basic Medical Sciences Chinese Academy of Medical Sciences METHODS:The Pichia pastoris contained rhIFN-?1 expressive plasmids was cultured and induced to express IFN-?1.The positive ion exchange chromatography and gel chromatography were used to purify the expression product.MAIN OUTCOME MEASURES:The physico-chemical characters of the purified product were tested.The product's IL-10R2 and IL-28R were investigated by RT-PCR and real-time quantitative PCR and its antitumor activity was tested by MTT analysis.RESULTS:The expressed product rhIFN-?1 yield reached to 9.23 mg/L,and its purity was near 90%.The isoelectric point of rhIFN-1 was 8.01,with molecular weight of 20 960.The expressions of IL-10R2 and IL-28R were detected in U937 cell.rhIFN-?1 could decrease the cell proliferation just like IFN-?2a,but this function was unclearly in the IL-28R cell.CONCLUSION:rhIFN-?1 can be highly expressed in Pichia pastoris,and its product has the physical and chemical characteristics consistent with natural IFN-?1,and the anti-tumor activity is similar to IFN-?2a,however,it is weak in decreasing the proliferation of relatively lowerintensity of receptor distribution in marrow-hematopoiesis system.
ABSTRACT
Objective To study the morphology, physiology, biochemistry and molecular biologic characteristics of Ochroconis gallopava which was firstly isolated from a pulmonary phaeohyphomycosis in China and compare it with a standard strain to assist in the clinical diagnosis and treatment. Methods The clinical isolate and standard strain were inoculated on SDA, PDA, CMA, CDA, BHIA and OA, respectively to observe the colony morphology and growth rate, and slide cultures were prepared and were examined under light microscope and electron microscope. Thermo-tolerance study, cycloheximide resistance test, API 20C, antifungal susceptibility test and PCR for the internal transcribed spacer of rDNA were also performed. Results Ochroconis gallopava grew rapidly on most media. The colonies appeared to be brown in color with smooth surface. There were aerial mycelia on SDA and PDA. Microscopic observations revealed pale brown and septate hyphae with club-shaped conidia. The growth of O. gallopava was optimal at 35 ℃ and was inhibited by cycloheximide. The two strains assimilated the same 14 glycogens, but 1 different, in API 20C AUX. MICs of fluconazole, itraconazole, amphotericin B and terbinafine were 32 ~ 64 ?g/mL, 1 ?g/mL, 2 ?g/mL and 0.25 ~ 0.5 ?g/mL, respectively. PCR results showed that the ITS segment was 743 bp with 3 bp difference in both strains. The length of 18S region was 506 bp, their sequences were the same entirely. Conclusions The clinical isolate is proved as a domestic strain of Ochroconis gallopava at the level of morphology, physiology, biochemistry and molecular biologic characteristics.
