Age-related macular degeneration(AMD)is a kind of degenerative diseases with complex pathogenesis and stimulation of multiple factors.It has become one of the major diseases causing-blindness in the elderly population in China.Recently,some epidemiological findings demonstrated that diabetes mellitus possibly is one of risk factors for AMD,and this will offers a new approach for the prevention and treatment of AMD.Thus,it is very important for US to strengthen the research of mechanism of AMD impacted by diabetes mellitus,pay more attention to the progress of AMD,search for a scientific and rational therapeutic way of improving the prognosis and elevate the quality of life in the patients with diabetes mellitus.

The association of polymorphisms of calcium channel?1 subunit ( Cav1.1 ) gene ( - 1551T/C at exon 11 ) with thyrotoxic periodic paralysis (TPP) was investigated by PCR-RFLP.The distributions and frequencies of - 1551TC + CC genotype and C allele in TPP group were significantly higher than those in hyperthyroidism (HT) and normal control (CON) groups.There was no statistic difference between HT and CON groups.Cavl.1 gene - 1551TC + CC genotype and allele may contribute to the development of TPP in male HAN population from North China.

Objective To investigate the relative histological change of transplanted domestic expanded polytetrafluoroethylene (e-PTFE), which were treated with different methods, in order to offer the referential data for clinical application. Methods e-PTFE treated with different methods was transplanted into subcutaneous tussue of rat. The samples harvested according to time sequence were examined by using histological and histochemical methods. Dynamic change of the structure between the e-PTFE and it's surrounded tissue was investigated based on the examination. Results Cell and tissue were observed on the inside of all the e-PTFE including the control group and the experiment groups. Heavy cell infiltration on the 3rd day was the most significant in control group, and the quantity of tissue ingrowth was also the most until the 28th day. The next was trimming group. The quantity of both cell infiltration and the tissue ingrowth in high pressure steamed group and forceps squeezed group were less than that in other groups. Conclusion Cell infiltration into domestic e-PTFE is significantly achieved since 72 hrs and fibrovascular ingrowth since the 7days after implanted e-PTFE under subcutaneous tissue of the rat. Different treatment methods of e-PTFE can affect the speed of tissue ingrowth into the e-PTFE, which could be a reference for clinic application of e-PTFE.

OBJECTIVE:To prepare compound tretinoin cream No I,No II and observe their effects on chloasma.METHODS:The cream was prepared by taking tretinoin,kojoic acid and allantoin as main components and adding base material.The tretinoin was encapsulated with ?-cyclodextrin.RESULTS & CONCLUSION:The prescription of compound tretinoin cream is rational,preparation technic being stable and therapeutic effect on chloasma is satisfactory.

Objective To investigate the effects of montelukast(MK),a selective cysteinyl leukotriene receptor 1 antagonist on interleukin(IL)-5 and eotaxin expression as well as serum total immunoglobulin E(IgE) production during MK treatment of mouse acute asthma airway inflammation.Methods Sensitized Balb/c mice were challenged by ovabumin(OVA)to establish the acute asthmatic mo-(del).Twenty-five mg/kg of MK(MK group) or Saline(Saline group)were given by intravenously for 3 days.Cellular infiltration of bronchoalveolar larvage fluid(BALF) were assessed by Wright staining.Production of IL-5 and eotaxin in the lung or BALF and serum IgE were determined by enzyme linked immunosorbent assay(ELISA).The expression of IL-5 and eotaxin mRNA were measured by semi-quantified reverse transcriptase-polymerase chain reaction(RT-PCR).Plasma MK level was determined by liquid chromatography.Results After 24 h OVA challenge,the numbers of total white blood cells,neutrophils and eosinophils(EOS)of BALF were(26.0?18.9)?10~7/L,(5.92?8.09)?10~7/L and(0.74?0.88)?10~7/L in MK treatment group.They were significantly reduced compared with those in Saline group,respectively(P80%.The level of IL-5 in BALF and lung tissue were(48.52?14.45) ng/L and(27.40?9.62) ng/g protein in MK group,which significantly declined compared with that in saline group;BALF eotaxin level declined too.Serum IL-5 and total IgE level were also significantly reduced;IL-5 mRNA expression in lung significantly decreased.Eotaxin and its mRNA expression in lung were not decreased significantly.Conclusion MK(exerts) its anti-inflammatory effect mainly through the suppression of IL-5 and IgE production.

Objective To provide Meta-analysis evidence of laparoscopic partial nephrectomy (LPN) vs open partial nephrectomy (OPN) in assisting clinical decision making.Methods By searching CHKD,PUBMED,Wanfang and VIP database self-built library up to June 30,2012,both Chinese and English literatures of LPN and OPN efficacy in controlled study were included with strict exclusion criteria by two independent screenings of the literature.Data extraction and quality assessment were done by using the RevMan 5.1 META analysis software.Results A total of four English and six Chinese literature were included in this Meta-analysis.There were 1636 cases of partial nephrectomies.Of these patients,794 cases were treated with LPN,842 cases were treated with OPN.Meta analysis results showed that:in terms of operative time (SMD =0.10,95％ CI-O.40-0.59,P =0.70),surgical complication (OR =1.03,95％ CI0.73-1.44,P =0.88),positive surgical margin (OR =1.64,95 ％ CI0.83-3.23,P =0.16),warm ischemia time (SMD =1.07,95％ CI-0.02-2.16,P =0.05),postoperative tumor recurrence (OR =0.58,95％ CI 0.26-1.30,P =0.18),there was no significant difference.But in terms of intraoperative blood loss (SMD=-1.08,95％CI-1.57--0.59,P＜0.01),postoperative hospital stay (SMD=-0.81,95％CI-0.97--0.65,P ＜0.01),the differences were significant in favor of LPN.Conclusion Comparing with OPN,LPN has advantages in intraoperative blood loss and post-operative hospital stay,no obvious advantages in operative time,surgical complications,positive surgical margin,warm ischemia time and tumor recurrence.

The modernization of Traditional Chinese Medicine (TCM) is urgent need of the modern theory of TCM, is a consensus. But, How to establish and what kind of modern TCM theory, is far from a consensus. Based on the summarization of the common law in the construction of scientific theory, we are trying to give a answer that are expected to form a consensus. Firstly, we have illustrated the trend that the development of TCM theory should learn from the life and medical sciences theory function and value; Secondly, we have proven that TCM and TCM theory belongs to the traditional medicine and theory and pointed out the limitation of the traditional medicine, TCM and its theory. And then we have revealed the inevitable trend of traditional medicine, TCM and its theory development at home and abroad, logically obtained the inevitable choice of constructing the modern TCM basic theory; Lastly, we have analyzed the different discipline new theory construction process and method at home and abroad and discovered the common five steps rule, put forward three principles and five steps of constructing modern TCM basic theory, demonstrated its important role during the theoretical revolution promoting Chinese Medicine theory from phenomenon description to mechanism clarification and the scientific value of Chinese Medicine theory in the domestic and foreign development trend.
