Objective To explore the microcosmic mechanism of pingyangmycin treating infantile proliferating capillary hemangiomas so as to find the optimal method for hemangiomas′ treatment.Methods Sixty samples of infantile proliferating hemangiomas were divided into control group(30 cases,aged from 2 days to 6 months) and experimental group(30 cases,aged from 2 to 6 months).Pingyangmycin was made into emulsion and smeared on the surfaces of the leision in experimental group with 3 times every day as well as only matrix in control group.The specimens were resected on d7,then made into pathological slices and electron microscope slices in order to observe the cells microcosmic structure changes and ultrastructure changes.Furthermore,the apoptotic indexes of two groups were detected by the molecular biology method(TUNEL test).Results The number of apoptotic cells were lower in control group(apoptotic index 18.87?13.67)but higher apparently in experimental group(apoptotic index 29.52?15.33).The difference between two groups was significant(t=2.842 P

Objective To study the development of visual function in blepharophimosis-ptosis-epianthusinversm syndrome(BPES) and evaluate the clinical effect of Multistage Correction.Design Retrospective case series.Participants 51 cases of BEPS in Beijing Tongren Hospital from June 2005 to May 2009.Methods Refraction and general ophthalmology were performed for each patient. Family history was inquired and corrected surgery were performed for every one.Main Outcome Measures Refraction,the length, width of palpebral fissure,and inner canthal distance were measured both preoperatively and postoperatively.Results 13 of the 51 cases had family history,27 cases had amblyopia and 12 cases had refractive error.4 cases combined with strabismus.Conclusions The risk of refractive error and amblyopia in patients with BPES is much higher than that of normal population,so careful regular visual follow -up and early surgery are necessary.BPES patients tend to have much more chance to get amblyopia,which will impact on the development of visual function,therefore surgery correction at early age is highly suggested.

BACKGROUND:Comparative study results between the efficacies of traditional Chinese medicine (TCM) therapy with Western medicine therapy in the treatment of knee osteoarthritis remain controversial. Currently, meta-analysis studies mainly focuson comparison of the efficacy between TCM and Western medicine,butlack investigations among TCM therapies. Itmakes usdifficult tofulyunderstand the efficacy of TCM therapy for knee osteoarthritis.
OBJECTIVE:To compare the efficacies of TCM therapy with intra-articular injection of hyaluronic acid for knee osteoarthritis using a networkMeta-analysis method.
METHODS:PubMed, The Cochrane Library (tissue 10, 2015), EMbase, CNKI, CBM, VIP, Wangfang databaseswere searchedup to October 20, 2015forrelevantrandomized controled trialsaddressingthe efficacies of TCM therapyversusintra-articular injection of hyaluronic acid for knee osteoarthritis. Two reviewers independently selected the studies, extracted information, and assessed the quality of included trials. Data extraction from eligible studies was pooled and meta-analyzed using Stata12.0 and WinBUGS1.4.3softwares. Odd ratios with their 95% confidence interval were estimated as effect size between treatments.
RESULTS AND CONCLUSION:A total of 59 randomized controled trials involving 6 155 patients with knee osteoarthritis and 12 treatment strategies were included. The results of network meta-analysis showed that TCM comprehensive therapy wassuperior to the TCM monotherapy and intra-articular injection of hyaluronic acid. Among thesetherapies, the efficacy of needle scalpel combined with acupuncture is optimal. TCM comprehensive therapies may be the best choice to treat patients with knee osteoarthritisofKelgren-LawrenceII-III. Morelarge-scaleand wel-designedrandomized controled trials are stil warranted due to the limitation of the present study.

Objective To analyze the clinical outcomes of Ludloff osteotomy and artificial metatarsophalangeal arthroplasty in the patients with severe hallux valgus and metatarsophalangeal joint osteoarthritis.Methods From Apr.2013 to Aug.2015,120 feet with severe hallux valgus were treated by operation in Beijing Friendship Hospital,Capital Medical University.Before operation,measured some angles,such as hallux valgus angle,intermetatarsal angle,proximal articular surficial intrinsic angle and so on in the two groups.And evaluated the patients condition by Maryland scale at the same time.Through the date,we make sure that there was no significant difference between the two groups before operation.According to the order of hospitalization,all patients were randomly divided into experimental group (n =60) and control group (n =60).The cases of experimental group were treated by Ludloff osteotomy and artificial joint replacement.The cases of control group were treated by Ludloff osteotomy and Akin osteotomy.We used the visual analogue scale,the core quality of life scale-36 and Maryland scale to record the date,such as pain,the range of motion and appearance of the metatarsophalangeal joint and the ability of daily life and sports before and after operation.Compared above categorical variables using paired T-test between before and after operation and using T-test between the two groups.Compared the rate of operative complications by Fisher's exact test between the two groups.Results Through the Maryland scale,the total excellent rate of the experimental group (91.7％) was higher than the total excellent rate of the control group (75.0％),with statistically significant (P ＜ 0.05).The operative complication rate of experimental group (1.7％) was lower than the control group (8.3％),but without statistically significant (P ＞0.05).The scores of quality of life of the experimental group after treatment were significantly higher than those of the control group,with statistically significant (P ＜ 0.05).The visual analogue scale pain score (1.61 ± 0.12) of the experimental group was significantly lower than the control group (3.68 ± 0.58),with statistically significant (P ＜ 0.05).Conclusion The clinical outcomes of Ludloff osteotomy and artificial metatarsophalangeal arthroplasty in patients with severe hallux valgus and metatarsophalangeal joint osteoarthritis is better,high safety,less trauma and faster recovery.It is worthy of promotion and use.

Objective To investigate the preventive effect of spironolactone on hepatic fibrosis. Methods Ninety SD rats were randomly divided into three groups. Control group consisted of 8 rats that , fed by normal food, were injected with peanut oil subcutaneously. Model group consisted of 42 rats whose liver fibrosis was induced by compound factors. Spiro nolactone-prevention group consisted of 40 rats that were given 100 mg?kg -1 spironolactone per day, by the same methods of making models as those of the model group. At the end of weeks 2, 4, 6 and 8, 8 rats were randomly taken out of model group and spironol actone group and then were sacrificed. The expressions of TGF- ? 1 , PDGF- BB and ? -SMA in hepatic tissues were detected with immunohistochemical met hods. Results The expressions of TGF- ? 1 , PDGF-BB a nd ? -SMA in spironolactone group decreased greatly than those in model gro up ( P

Viable but non-culturable state in bacterial cells as received uncultured microorganism has be- come the fundamental research issues in medical microbiology, epidemiology, general microbial ecology and sanitation quarantine since it was put forward in 1982. When in this state, bacterium are no longer able to grow and form colonies on conventional culture media, but maintain their patheogenicity, may become latent infection escaping detection to threaten enviroment and human security. With the development of modern molecular biology technique and metagenomics, it provide new research method and opportunity for uncul- tured microorganism in the environment. Recently, with the application of the metagenome technique, ge- netic fingerprinting technical etc, it becomes more and more popular. Simultaneously, along with this state become maturity in the laboratory. It provides a new research route for development and exploitation the uncultured microorganism.

OBJECTIVETo reveal the relation between endogenous hormones and the flower bud differentiation in Schisandga chinensis.

METHODTop buds of extremely short branch and axillary buds of long branch in the same plant of S. chinensis were used as material and the contents of endogenous hormones were measured during different periods of the flower bud differentiation with HPLC.

RESULTThe result showed that flower bud differentiation and the formation of female flower were inhibited by high concentration of GA3 and were promoted by high concentration of ABA or ZT. Low ratio of GA3/ABA has the same result.

CONCLUSIONThere was a correlation between endogenous hormones and the flower bud differentiation of S. chinensis.
