OBJECTIVETo observe the curative effect of Qianjin Kouchuang Jiawei Granule (QKJG) on recurrent oral ulceration [yin deficiency fire excess type (YDFET)].

METHODSTotally 120 patients who suffered from recurrent oral ulceration (YDFET) were randomly assigned to two groups, the experiment group and the control group, 60 in each group. Patients in the experiment group took QKJG, 20 g each time, twice per day, while those in the control group took Kouyanqing Granule (KG) , 20 g each time, twice per day. Fourteen days consisted of one therapeutic course, two for all. Scores for patients' symptoms and signs (ulcer area, exudation, hyperaemia, edema, the number of ulceration, burning sensation, and pain degrees) were assessed before treatment, at day 3 and 7 after treatment. Short-term efficacy was assessed by visual analogue scale (VAS). The total paralysis time and the total number of ulceration at month 12 after treatment were taken as judgment for long-term efficacy. Results Compared with before treatment in the same group, symptoms and signs were obviously improved at day 3 and 7 after treatment in the two groups (P < 0.05). Compared with the control group at day 3 after treatment, the improvement of edema, exudation, pain degree, and burning sensation was more obvious in the experiment group (P < 0.05, P < 0.01). The improvement of edema, pain degree, and burning sensation at day 7 after treatment was more obvious in the experiment group than in the control group (P < 0.05). As for short-term efficacy, the total effective rate was 86.67% (52/60 cases) in the experiment group and 83.33% (50/60 cases) in the control group, with no statistical difference between the two groups (P > 0.05). As for long-term efficacy, the total effective rate was 90.00% (54/60 cases) in the experiment group, significantly higher than that of the control group with statistical difference [81.67% (49/60 cases), P < 0.05]. At month 12 after treatment, the total number of ulceration was reduced and the paralysis time of ulcer attack prolonged in the experiment group, with statistical difference when compared with the control group (P < 0.05).

CONCLUSIONQKJG showed better long-term efficacy than that of KG in treating recurrent oral ulceration (YDFET).

Objective To report 6 cases of hydroa vacciniforme-like cutaneous lymphoma,and to inves- tigate the relationship between this disorder and Epstein-Barr virus(EBV)infection.Methods Pathological and immunohistochemical examinations were performed in the biopsy specimens obtained from all 6 patients. Skin lesions were subjected to EBV encoded RNA(EBER)detection by in situ hybridization.Serological assay and quantification of EBV DNA were performed.Results All the 6 patients had recurrent papules, papulovesicles,necrosis and variola-like scar with chronic intermittent fever;four of the patients also presented with edema of the face,hands and feet.Pathologically,there were multilocular vesicles in the epidermis,and large numbers of infiltrating lymphocytes through the dermis.The cells were atypical with mitotic figures. Immunohistochemical staining of the lesions of 4 patients showed large quantities of cells expressing CD56, scattered cells expressing CD3 and CD45RO,and cells expressing grazyme B and T cell intracellular antigen-1 (TIA-1);a diagnosis of hydroa vacciniforme-like cutaneous NK/T lymphoma was made in these 4 cases. In the lesions of another 2 patients,the cells expressing CD3 and CD45RO,but not CD56,were observed; the diagnosis of hydroa vacciniforme-like cutaneous T-cell lymphoma was made in them.EBER was detected in the tumor cells of all the 6 patients.The IgG titers of anti-Epstein-Barr viral capsid antigen increased in all patients(1:5120 in 2 cases,1:2560 in 2 cases,1:1280 in 2 cases).The copies of EBV DNA were increased in the peripheral blood of both the two detected cases.A chronic active EBV infection was confirmed in all patients.Conclusions Hydroa vacciniforme-like cutaneous lymphoma is clinically characterized by edema of face,hands and feet,vesicular eruptions and variola like scars;histologically,it is characterized by infiltrates of atypical cells consistent with lymphoma,and necrosis in the center of vessels.NK/T is the primary immunophenotype of this disease.There is a close association between chronic active EBV infection and hydroa vacciniforme-like cutaneous lymphoma.

Background Though nitric oxide (NO) and NO synthase (NOS) have a critical role in angiogenesis,their effects on corneal neovascularization (CNV) and mechanism need to be further explored.Objective The aim of this study was to explore the effects of NOS and its antagonist,Nw-nitro-L-arginine methyl ester (L-NAME) on experimental CNV in mice,and investigate the influence of NOS and L-NAME on the tube formation of human retinal endothelial cells (RECs) in vitro.Methods The CNV models were established in the left eyes of 36 male BALB/c mice aged 7-8 weeks by application of the filter paper with NaOH in the center of corneas.The mice were randomized into two groups.L-NAME of 10 g/L (0.5 ml) was intraperitoneally injected 1 week before induction of CNV three times a week for three weeks in the mice of the L-NAME injection,and PBS was used in the same way in the control group.CNV was examined under the slit lamp biomicroscope 2,4,7,14 days after NaOH burn.The expression of CD31 in the CNV was assayed to calculate the ratio of CNV area and total corneal area using whole mount technique.The expression of NOS mRNA in the corneal tissue was detected by reverse transcriptase polymerase chain reaction (PCR),and VEGF expression in the human RECs was assayed by Western blot.The vessel formation number of cultured human RECs with or without L-NAME was performed by matrigel in vitro.Grouped t test was used to compare the differences of the parameters between the two groups.Results CNV developed and peaked 2 weeks after the application of NaOH on the mice corneas,and the CNV was obviously less in the L-NAME group compared with the control group.The expression of NOS mRNA in the corneas (NOS mRNA/ GAPDH mRNA)was significantly lower in the L-NAME group than that of the control group 2,4,7 days after CNV induction (t =19.481,t=22.059,t=10.961,all at P＜0.01).The ratio of the CD31 positive area in whole corneal area was 0.59± 0.01 in the L-NAME group,and that of the control group was 0.78±0.10,showing a significant difference between the two groups (t =3.078,P＜0.05).Western blot assay showed that the relative expression of VEGF protein in human RECs was declined in the L-NAME group compared with the control group 0,2,4,7 days,with statistically significant differences in 4 days and 7 days after NaOH burn(t=7.696,t=17.953,both at P＜0.01).The number of vessel network was 46.33±1.86 in the L-NAME group and 64.00±4.51 in the control group,with a significant difference between them (t =3.623,P＜0.05).Conclusions NOS participated in the pathogenesis and aggravation of CNV induced by NaOH.L-NAME arrests CNV formation and human RECs tube formation through down regulating the VEGF expression and NOS activity.

Chronic osteomyelitis is one of the most common disorder in clinic. In recent years due to diabetes, peripheral vascular disease and trauma induced disease increased, the prevalence rate increased. With the development of magnetic resonance imaging and CT imaging technology, it greatly improved the accuracy of clinical diagnosis of chronic osteomyclitis and ability to describe the infection characteristics, and provide a reliable basis for clinical treatment. The current research on chronic osteomyelitis mainly concentrated on the aspects of imaging applications and ways of using antibiotic optimization control inflammation, defect restoration and reconstruction of blood supply and treatment. But the best time to the antibiotic therapy and the use of program is still uncertain, for after debridement, bone grafting time and defect repair function of fast recovery still need further research.

OBJECTIVETo observe the clinical efficacy of treating chronic persistent bronchial asthma (CPBA) children with abnormal myocardial enzyme spectrum (AMES) by Yupingfeng Powder (YP) combined routine therapy.

METHODSFrom January 2010 to December 2012, 156 CPBA children patients with AMES were randomly assigned to the treatment group (80 cases) and the control group (76 cases). All patients received routine treatment (inhaled corticosteroids and/or leukotriene regulator). Besides, those in the treatment group took YP. The treatment duration was 3 months. The scores of children asthma control test (C-ACT), pulmonary function (FEV,% and PEF%), myocardial enzyme spectrum were observed before and after treatment, and 3 months before and after treatment. The myocardial enzyme spectrum of 40 healthy children at the baby clinics during the same period were recruited as the control.

RESULTSCompared with the control group, creatine kinase isoenzyme (CK-MB), creatine kinase(CK), and lactate dehydrogenase (LDH) increased in the two treatment groups (P <0.01), but there was no statistical difference in AST (P >0.05). Compared with before treatment in the same group, CK-MB, CK, LDH, and AST decreased in the treatment group after treatment and 3 months after treatment (P <0.01). CK-MB, CK, LDH, and AST decreased in the control group 3 months after treatment (P <0.01, P <0.05).Compared with after treatment, CK decreased in the control group 3 months after treatment (P <0.01). C-ACT score, FEV(1),%, and PEF% all increased in the two groups after treatment and 3 months after treatment (P <0.01, P <0.05). Compared with after treatment in the same group, CK decreased in the control group 3 months after treatment (P <0. 01). Compared with the control group in the same period, post-treatment CK-MB and CK decreased (P <0. 01, P <0. 05), while post-treatment C-ACT score, FEV, %, and PEF% increased (P <0.05) in the treatment group (P <0.05).

CONCLUSIONYP could strengthen specific and non-specific immunity of the organism, and improve clinical symptoms and the level of myocardial enzyme spectrum.

Objective To observe the diurnal variation of intraocular pressure(IOP)measured with Goldmann applanation tonomoter(GAT)in patients with primary open angle glaucoma(POAG),normal tension glaucoma(NTG)and healthy controls,and to compare the differences of diurnal variation curves between two eyes of each subject and define the distribution of the peak of IOP. Design Prospective case series.Participants POAG patients,NTG patients and healthy controls.Methods The diurnal variation of IOP in the two eyes of each of 30 POAG patients,30 NTG patients and 30 normal controls were investigated and the distributions of the peak IOP were observed.Main Outcome Measure Intraocular pressure.Results Measured with GAT,6.7% right eyes and 10.0% left eyes of normal people,20.0% right eyes and 23.3% left eyes of NTG patients,and 23.3% right eyes and 20.0% left eyes of POAG patients showed peak IOP at the time points of out-office period.Conclusions POAG patients,NTG patients and normal controls have asymmetric IOP diurnal variation.The two eyes of one individual cannot always be treated as the same.The IOP peak can occur at the time point during the out-office time.Measure IOP in office-time only may miss the dynamic information of IOP.

Epiberberine, one of the most important isoquinoline alkaloid in Coptidis Rhizoma, possesses extensive pharmacological activities. In this paper, the liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to study phase I and phase II metabolites. A Thermo HPLC system (including Surveyor AS, Surveyor LC Pump, Surveyor PDA. USA) was used. The cocktail probe drugs method was imposed to determine the content change of metoprolol, dapsone, phenacetin, chlorzoxazone and tolbutamide simultaneously for evaluating the activity of CYP2D6, CYP3A4, CYP1A2, CYP2E1 and CYP2C9 under different concentrations of epiberberine in rat liver microsomes. The result showed that epiberberine may have phase I and phase II metabolism in the rat liver and two metabolites in phase I and three metabolites in phase II are identified in the temperature incubation system of in vitro liver microsomes. Epiberberine showed significant inhibition on CYP2D6 with IC50 value of 35.22 μmol L(-1), but had no obvious inhibiting effect on the activities of CYP3A4, CYP1A2, CYP2E1 and CYP2C9. The results indicated that epiberberine may be caused drug interactions based on CYP2D6 enzyme. This study aims to provide a reliable experimental basis for its further research and development of epiberberine.

To figure out the stability and intestinal bacteria metabolites of rats in vitro of astragaloside IV ( AST), this research was done to explore the stability of AST in the artificial gastric juice. artificial intestinal juice and rat liver homogenate and the metabolism in rat intestinal in vitro. HPLC was used to calculate the remaining rate of AST in biological samples by measuring the content of AST, while metabolites were determined by combining the methods of TLC, HPLC and LC-MS/MS. It turned out that AST was difficult to metabolize in the artificial gastric juice, artificial intestinal juice and rat liver. Also, the metabolic pathway of AST was stepped by deglycosylation. Firstly, AST was converted to its secondary etabolites (6-O-β-D-glucopyranosyl- cycloastragenol, CMG) by removal of xylose moiety at C-3, then transformed into cycloastragenol (CAG) after hydrolytic removal of the glucose moiety at C-6. All the results suggested that the metabolism of AST in vivo occurs mainly in the intestinal by hydrolysis of glycosyl. In conclusion, hydrolysis of intestinal flora is the main reason that AST metabolizes.
