AlM: To silent hypoxia inducible factor-1α ( HlF-1α) gene in malignant melanoma of the choroid cell by small interference RNA ( siRNA ) and investigate its effect on the expression of matrix metalloproteinase-2 ( MMP-2 ) in the choroid cell line human uveal melanoma cell (OCM-1) in hypoxia environment.METHODS:OCM-1 cells cultured on culture flask were divided into normal group and hypoxia group. Hypoxia group were divided into five groups: simple hypoxic group, and interference group, and negative control group, and positive control group, and liposome group. Normal group cells were cultured on DMEM culture flask with 10% FBS, 100U/mL penicillin, 100μg/mL streptomycin as well as high concentration of glucose. The cells were maintained at 37℃ in a humidified 5% CO2 incubator. Cells in good condition were selected for experiment. For hypoxia group, chemical hypoxia inducer CoCl2 was added into nutrient medium at the concentration of 100μmol/L to simulate hypoxia microenvironment. We designed and synthesised siRNA ( siRNA + negative control+positive control ) , the target sequences of the HlF-1α to transfect hypoxic malignant melanoma of the choroid cell. SiRNA including HlF-1α siRNA, β-actin siRNA and negative control group synthesized in vitro transfected hypoxic OCM - 1 cell through Lipofectamine2000. The expression of HlF-1α, MMP-2 gene and the protein were detected by RT-PCR and Western blot. RESULTS: Compared with the normal group, the expression of HlF-1α mRNA was not obviously changed (P>0. 05), but the expression of HlF-1α protein and MMP- 2 mRNA protein was significantly higher ( P<0. 05) . Compared with the other hypoxia groups,β-actin mRNA expression of positive control group decreased ( P< 0. 05 ) , which proved successful transfection. The expression of HlF-1α mRNA and the expression of its protein and both MMP-2 mRNA and its protein was significantly lower ( P < 0. 05 ). The negative control group, liposome control group had no significant difference in the detection of factors (P>0. 05).CONCLUSlON: Hypoxia status may upregulate the HlF-1α in OCM-1 cells by increasing the expression of protein. Hypoxia can also inactivate MMP-2, resulting in upregulation of MMP-2 RNA and the expression of its protein. The expression of HlF-1α and MMP-2 mRNA can be down-upregulated by transfecting OCM-1 with HlF-1α siRNA.

OBJECTIVETo explore the temporal profile of serum antibody against coronavirus in patients with severe acute respiratory syndrome (SARS), and to evaluate the reliability of indirect immuno-fluorescence assay (IFA) in the diagnosis of SARS.

METHODSClinically confirmed SARS patients, suspected SARS patients, and controls were included in the study. IFA was used to detect the serum antibody against SARS coronavirus. General information about the subjects was collected using a standard questionnaire.

RESULTSThe positive rates of specific IgG and IgM against SARS virus within 10 days after onset of the disease were 55.1% and 16.3% respectively and then increased up to 89.8% for IgG and 65.3% for IgM. After 25 days of the onset of the disease, 90.9% patients became positive for both IgG and IgM. Results from chi-square for trend test revealed that the positive rates of both IgG and IgM increased with time (chi(2) for trend = 16.376, P = 0.00005 for IgG; chi(2) for trend = 28.736, P = 0.00000 for IgM). Sensitivity, specificity and agreement value of IFA regarding the diagnosis of SARS were all higher than 90%.

CONCLUSIONIFA can be used to assist diagnosis of SARS after 10 days of the onset of disease.

OBJECTIVETo investigate the relationship between renal clear cell carcinoma and type 2 diabetes mellitus (DM).

METHODSTwo hundreds and sixty-four patients with renal clear cell carcinoma and four hundred controls who suffered from non-urinary system, non-neoplastic or non-hormone-related disorders, were enrolled from January 2008 to December 2012. The incidence of diabetes between the 2 groups and the relationship between renal clear cell carcinoma and duration of diabetes were compared, moreover, renal clear cell carcinoma patients with DM were compared with patients without DM for their clinical features, laboratory examinations and histological characteristics.

RESULTSThe comparison of renal clear cell carcinoma group and control group: the incidence of DM in the two groups were 19.7% and 12.8% respectively, and the difference was significant (χ(2) = 5.86, P < 0.05, OR = 1.68). In the renal clear cell carcinoma group, the proportion of patients with DM diagnosed within 2-4 years was 4.92%, which were significant higher than those in the control group 1.70% (χ(2) = 5.49, P < 0.05, OR = 2.91). And men with diabetes had high occurrence risk 86% of renal clear cell carcinoma (OR = 1.86, 95%CI: 1.09-3.15). The comparison of diabetes patients subgroup and non-diabetic patients subgroup in renal clear cell carcinoma group: in respect of clinical features, greatest tumor diameter in the two subgroups were (4.9 ± 2.3) cm and (4.2 ± 2.1) cm respectively, and the difference was significant (t = 1.96, P < 0.05). However, there was no significant difference in terms of age, gender and cancer location between the two subgroups (P > 0.05). In respect of laboratory examinations, serum creatinine in the two subgroups were (72 ± 20) µmol/L and (65 ± 17) µmol/L, and the difference was significant (t = 2.34, P < 0.05); serum urea nitrogen in the 2 subgroups were (7.1 ± 2.1) mmol/L and (6.0 ± 1.5) mmol/L respectively, and the difference was significant too (t = 1.47, P < 0.05). In respect of histological characteristics, the proportion of well differentiated clear cell carcinoma were 80.8% and 81.1% respectively, and the difference was significant (χ(2) = 4.23, P < 0.05). The proportion of stage II were 25.0% and 27.8% respectively and the difference was significant (χ(2) = 4.08, P < 0.05).

CONCLUSIONSDM is closely related with renal clear cell carcinoma and DM may be a possible risk factor for the tumor. And for elderly patients with diabetes who appear waist discomfort or hematuria, a careful examination of kidney is important to make early diagnosis, give timely treatment and improve survival prognosis.

Vitiligo is a common pigmentary disorder characterized by localized or generalized depigmentation of the skin， resulting in milky white or light pink patches with smooth surface but no rashes.Modern medicine believes that it is closely related to immune function， oxidative stress， autoimmune destruction of melanocytes， heredity， and neurochemical factors， but the specific pathogenesis is still unclear.Due to the easy diagnosis but hard management and the high recurrence rate， vitiligo has seriously affected the quality of life and mental health of patients.At present， it is mainly treated with glucocorticoids， immunomodulators， vitamin D₃ derivatives， and antioxidants in western medicine， and the resulting short-term outcomes are satisfactory.However， a series of side effects may be caused by the long-term use.Traditional Chinese medicine （TCM） has a long history of dealing with vitiligo.Guided by the rich experience accumulated in daily practice， it exerts the preventive and therapeutic effects against vitiligo via multiple components， multiple targets， and multiple pathways， without inducing obvious adverse reactions， which has made it widely concerned by many doctors and scholars.As the research concerning the prevention and treatment of vitiligo with TCM intensifies， more and more single Chinese medicinals， Chinese medicinal monomers， and compound prescriptions have been proved to play a therapeutic role via multiple mechanisms.After reviewing the articles on the alleviation of vitiligo with TCM published in the past five years and retrieved from the literature databases， this paper summarized the efficacy of TCM in regulating immune dysfunction， improving oxidative stress injury， protecting melanocyte function， adjusting mitochondrial structure and function， and controlling the alteration of intestinal micro-flora and abnormal microRNA （miRNA） expression， so as to clarify the pathogenesis of vitiligo and provide theoretical and scientific basis for the in-depth study and clinical application of TCM in the prevention and treatment of vitiligo.

Atopic dermatitis is a chronic， refractory and inflammatory skin disease with the clinical manifestations of severe pruritus and recurrent attacks. It has a high incidence and is closely correlated with other allergic， autoimmune or infectious diseases， which can cause a variety of secondary diseases and mental and psychological disorders， seriously affecting the life quality of patients. Chinese herbal medicines have been used for the prevention and treatment of atopic dermatitis for thousands of years， and many Chinese herbal medicines （including compound prescriptions） effective for this disease have been recorded. These medicines generally have little adverse reactions and the treated patients have low recurrence rate of atopic dermatitis. According to the evidence of modern medicine， the onset of atopic dermatitis is related to the impairment of skin barrier function， abnormal immune response， and abnormal differentiation of mast cells， antigen-presenting cells， and eosinophils. Additionally， it is associated with mental， endocrine， metabolic and other factors. The defect of skin barrier function and the dysfunction of immune system are the main pathogenesis of atopic dermatitis. In recent years， scientists have achieved certain progress in improving skin barrier function with Chinese herbal medicines. This paper systematically summarizes the studies about the application of Chinese herbal medicines in regulating the expression of epidermal proteins， epidermal lipids， aquaporins， tight junction proteins， and antimicrobial peptides in recent 10 years， aiming to clarify the pathological mechanism and provide reference for the clinical research and application of Chinese herbal medicines in the treatment of atopic dermatitis.

Atopic dermatitis （AD） is a chronic， recurrent and inflammatory skin disease. Modern medical research suggests that AD is related to immune function， genes， skin barrier and other factors， while the specific etiology and pathogenesis remains unclear. The disease has a long course and is prone to reoccur， which seriously affects people’s production and life. Steroids， antihistamines and immunosuppressants are commonly used western medicines for the treatment of AD， which， however， will cause adverse reactions after long-term application. Traditional Chinese medicine （TCM） has a long history， good therapeutic effect and rich clinical experience in the prevention and treatment of AD， and the research on the treatment of AD with TCM has been intensifying. Centering on the theory of TCM， we systematically summarized the research progress related to AD， discussed the etiology and pathogenesis of AD， and summarized the TCM syndrome differentiation of AD from the aspects of eight principles， etiology， Qi-blood-body fluid， zang-fu organs， six meridians， defense-Qi-nutrient-blood and triple energizer. According to the etiology and pathogenesis of AD， we proposed the therapeutic regimens corresponding to the type and stage of the disease. Considering the research progress achieved in the recent years in the prevention and treatment of AD by TCM and the modern pharmacological research on Chinese medicinal materials， we reviewed the classic famous prescriptions， self-made prescriptions and Chinese patent medicines， and expounded the mechanisms of single Chinese medicinal materials in the treatment of AD at the molecular level. The TCM external therapies such as wet compress， medicated bath， gel and ointment are safe and effective. Acupuncture and moxibustion play a role in the prevention and treatment of AD， which is worthy of promotion in clinical practice， and the syndrome differentiation methods of Qi-blood-body fluid and triple energizer are novel in the treatment of this disease. TCM， characterized by diverse therapeutic methods and good clinical efficacy， is worthy of promotion in the treatment of AD， which will contribute to the development of TCM in China.

Brazilein is an active small molecular compound extracted from Caesalpinia sappan L. with favorable pharmacological properties on immune system, cardiovascular system, and nervous system. C. sappan has been used as a traditional medicine in China for hundreds of years for various diseases. However, the general reproductive toxicity of brazilein is still unknown. The purpose of the present study was to thoroughly evaluate the general reproductive toxicity of brazilein in ICR mice to support the future drug development and modernization of this potent traditional Chinese medicine. The results showed that, although no apparent toxicity on the reproducibility of the male was observed, brazilein might cause considerable risks to the fetuses and females as indicated by the ratios of dead fetuses and reabsorptions. In conclusion, our results from the present study provided some useful insights about the safety profile of brazilein, suggesting that brazilein should be used with caution in pregnant women.
