Objective To summariza the clinical and histological features of linear cutaneous lupus erythematosus (LCLE).Methods Six cases of LCLE were analyzed retrospectively.Results LCLE was often clinically characterized by unilateral.zonal or linear,dark-erythematous patches with telangiectasia,and some lesions were covered with adherent Scales.Histologically,there were patchy perivascular and periadnexal lymphoid inflammatory infiltrate occurring in the superficial and deep dermis.Some cases were pathologically manifested by parakeratosis of superficial dermis,follicular plugging and hydropic degeneration of the basal layer of the epidermis,which was characteristic of discoid lupus erythematosus.The preferred treatment was chloroquine for LCLE.Low dose of corticosteroids were recommended for widespread lesions,especially for those pathologically manifested by lymphocyte infiltrates in the lower dermis and fat tissue.Conclusion The diagnosis of LCLE should be based on clinical and histopathological manifestations.

Objective:To explore the lipid-regulating effect and safety of atorvastatin combined fenofibrate therapy in patients with coronary heart disease (CHD)complicated diabetes mellitus (DM).Methods:A total of 100 pa-tients with CHD complicated DM were enrolled.Based on routine treatment,patients were randomly and equally di-vided into statin group (n=50,received 20mg atorvastatin,once/night)and combined treatment group (n=50,re-ceived 20mg atrovastatin once/night,combined fenofibrate 200mg once/d).Serum levels of total cholesterol (TC), triglyceride (TG),low density lipoprotein cholesterol (LDL-C)and high density lipoprotein cholesterol (HDL-C) were measured before,six and 12 weeks after treatment,levels and standard-reaching rates of above blood lipid were observed before and after treatment;adverse reactions and clinical events were recorded.Results:Compared with before treatment after six-week treatment,there were significant reductions in serum levels of TC,TG and LDL-C in both groups,and they further decreased after 12-week treatment (P <0.05~ <0.01),compared with statin group after 12-week treatment,there were significant reductions in levels of TC [(4.35±0.71)mmol/L vs. (4.09±0.56)mmol/L],TG [(2.35±0.62)mmol/L vs.(1.65±0.49)mmol/L]and LDL-C [(2.01 ±0.39) mmol/L vs.(1.85±0.22)mmol/L]in combined treatment group,P <0.05 or <0.01;HDL-C level significantly rose in both groups after treatment,and it′s more significant after 12 weeks,but there was no significant difference between statin group and combined treatment group (P >0.05).After 12-week treatment,standard-reaching rates of LDL-C,TG,HDL-C,all standard-reaching of above three indexes and non HDL-C (70%,68%,80%,58% and 70%)in combined treatment group were significantly higher than those of statin group (50%,46%,48%,10% and 48%)respectively,P <0.05 or <0.01. No severe adverse reactions were observed in two groups during treatment. Conclusion:Atorvastatin combined fenofibrate treatment is more effective than atorvastatin monotherapy in patients with coronary heart disease complicated diabetes mellitus.It can improve blood lipid level more comprehensively, contribute to comprehensive standard-reaching of blood lipids,and possess better safety and tolerance.

Objective To investigate the activation of nuclear factor-B (NF-B)and hypoxia-inducible factor-1 (HIF-1)in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods Subjects were classified into mild-to-moderate OSHAS group (n = 16), severe OSAHS group (n = 14) and the matched control group (n=30). Gene and protein expressions of NF-B and HIF-1 were measured by RT-PCR, Western blot in peripheral blood mononuclear cells (PBMC). Results NF-κB p65 mRNA and NF-κB p65 protein,HIF-1α mRNA and HIF-1α protein in PBMC were significantly higher in severe OSAHS group than those in mild–to-moderate group and control group (P<0.01). But there were no significant difference in NF-κB p65 mRNA and NF-κB p65 protein between mild-to-moderate group and control group (P=0.068, P=0.254 respectively). Only gene (P<0.05) not the protein (P=0.777) of HIF-1αwas higher in mild-to-moderate as compared with control group. Both NF-κB p65 mRNA and HIF-1αmRNA were positively correlated with AHI (r=0.493, P=0.006, r=0.508, P=0.004), while negatively correlated with nighttime lowest blood oxygen saturation (LSaO2)(r=-0.488, P=0.006, r=-0.46, P=0.011). There was a positive correlation between NF-κB p65 protein level and AHI (r=0.669, P<0.001). HIF-1αprotein level was positively correlated with AHI, ODI (r=0.628, P=0.001;r=0.480, P=0.018). There were positive correlations between NF-κBp65mRNA and HIF-1αmRNA (r=0.543, P=0.002), NF-κBp65 and HIF-1αprotein respectively (r=0.716, P<0.001). Conclusions As the gene and protein of NF-κB and HIF-1 were up-regulated in patients with OSAHS, and also positively correlated with the severity of sickness. We conclude that both NF-κB and HIF-1 were involed in the pathogenesis of OSAHS.

Objective To analyze the characteristics of bone scintigraphy in 117 cases with primary hyperparathyroidism (PHPT).Methods Of these 117 cases (50 males and 67 females),there were 116 parathyroid adenomas and 1 parathyroid cancer.Mean age was 61.1(12-86) years old.All had ~(99)Tc~m-methylene diphosphonate (MDP) bone scintigraphy.The bone images could be classified into 4 categories.Category Ⅰ:normal;category Ⅱ:localized abnormal,which could be subcategorized as Ⅱ A with skull and mandible involvement,and Ⅱ B with Ⅱ A characteristics plus metabolic derangement;category Ⅲ:systemic,whole-body incmased tracer uptake;category Ⅳ:systemic plus localized metabolic derangement.Data were analyzed statistically with X~2 and t-test (isolated samples).Results According to the scintigraphic findings,there were 47 cases(40.17%)of category Ⅰ,35 cases(29.91%) category Ⅱ (21/35cases Ⅱ A and 14/35 cases Ⅱ B),30 cases (25.64%) category Ⅲ,and 5 cases (4.27%) category Ⅳ.Combining categories Ⅱ、Ⅲ and Ⅳ together,there were 70 abnormal cases.These patients had history of abnormal bone images such as bone fracture (39 cases,55.71%),calculus (8 cases,11.43%),bone fracture plus calculus(7 cases,10.00%),osteoporosis (51 cases,72.86%) or ostalgia(26 cases,37.14%);however,in the 47 cases of category Ⅰ,only 1 (2.13%),0,0,10(21.28%)and 10 cases (21.28%),respectively,were found.Therefore.these case history characteristics were statistically significant (X~2=11.152,P=0.01).The tumor size,parathyroid hormone (PTH),blood calcium,blood phosphorus in the patients of abnormal PHPT categories Ⅱ to Ⅲ were(14.52±13.72)cm~3,(731.67±618.40)ng/L,(3.05±0.29) mmol/L and (0.71±0.14) mmol/L,respectively.with statistically significant difference compared to category Ⅰ:(0.78±1.33) cm~3,(112.04±62.98)ng/L,(2.56±0.42) mmol/L and (1.03±0.36)mmol/L(t=-5.724,-5.741,-7.274 and -6.451;all P＜0.01).Conclusions (1)Bone scintigraphy was normal in 40% of PHPT patients.(2)The bone images of PHPT could be classified into 4 categories and each could reflect the duration and severity of the disease status on bone.(3)The bone imaging characteristic could be useful for differential diagnostic purposes.

The purpose of this study is to investigate the effect of superparamagnetic chitosan FGF-2 gelatin microspheres (SPCFGM) on the proliferation and differentiation of mouse mesenchymal stem cells. The superparamagnetic iron oxide chitosan nanoparticles (SPIOCNs) were synthesized by means of chemical co-precipitation, combined with FGF-2. Then The SPCFGM and superparamagnetic chitosan gelatin microspheres (SPCGM) were prepared by means of crosslinking-emulsion. The properties of SPCFGM and SPIONs were measured by laser diffraction particle size analyser and transmisson electron microscopy. The SPCFGM were measured for drug loading capacity, encapsulation efficiency and release pharmaceutical properties in vitro. The C3H10 cells were grouped according to the different ingredients being added to the culture medium: SPCFGM group, SPCGM group and DMEM as control group. Cell apoptosis was analyzed by DAPI staining. The protein expression level of FGF-2 was determined by Western blot. The proliferation activity and cell cycle phase of C3H10 were examined by CCK8 and flow cytometry. The results demonstrated that both of the SPIOCNs and SPCFGM were exhibited structure of spherical crystallization with a diameter of (25 ± 9) nm and (140 ± 12) μm, respectively. There were no apoptosis cells in the three group cells. Both the protein expression level of FGF-2 and cell proliferation activity increased significantly in the SPCFGM group cells (P < 0.05). The SPCFGM is successfully constructed and it can controlled-release FGF-2, remained the biological activity of FGF-2, which can promote proliferation activity of C3H10 cells, and are non-toxic to the cell.

Objective To observe the effect of Shoutaiwan on the expression ofα-enolase in the decidua tissue of recurrent abortion mice. Methods The abortion-prone CBA/J × DBA/2 matings were established as the model of recurrent abortion and the nonabortion-prone CBA/J×BALB/C matings were used as the model of normal pregnancy. The model of recurrent abortion CBA/J × DBA/2 of pregnant mice were randomly divided into model group and Shoutaiwan high-, medium-, low-dose groups, pregnant mice of every group were orally administrated in different doses. On the 14th day of pregnancy, the mice were killed. The expression ofα-enolase was detected by using immunohistochemical method and Western Blot. Results α-enolase expression in the model group was significantly higher than the normal pregnancy group (P<0.01). Compared with the model group, Shoutaiwan low-, medium- and high-dose group significantly decreasedα-enolase expression of pregnant mice (P <0.01). Compared with high-dose group, Shoutaiwan medium-and low-dose group showed no significant difference (P>0.05). Conclusion Shoutaiwan could down-regulate the expression ofα-enolase in the decidua tissues of recurrent abortion mice, which may be one of its mechanisms of preventing miscarriage.
