Objective To study the effects of matrine on accumulation of ? globin mRNA and induction of erythroid differentiation in K562 cells in vitro.Methods K562 cells were cultured for 6 days with different concentration of matrine,viable cell counts were determined by trypan-blue dye exdusion test. Erythroid differentiation was evaluated by percentage of benzidine-positive cells at different days after culture. Morphological changes were observed under microscope after Wright-Gimesa staining; ? globin mRNA was quantitative by real time quantitative reverse transcript polymerase chain reaction(RT-PCR).Results Different concentrations of matrine inhibited proliferation of K562 cells in dose-dependent manner; otherwise, K562 cells were successfully induced by erythroid differentiation with matrine. After treatment with matrine, percentage of benzidine-positive cells significantly increased from 0.7% to 15.7% and characteristic changes of erythroid differentiation in the cell morphology were observed, G? globin mRNA had a preferential increase (2.7 fold)in K562 cells. Conclusions Matrine accumulation G? globin mRNA and induced erythroid differentiation of K562 cells. The results provides an experimental evidence for the pharmacological therapy of hematological diseases associated with a failure in the expression of normal ? globin genes.

· Vascular endothelial growth factor is indispensable inducing factor in retinalangiogenesis. After the retinal neovascularization of proliferative diabetic retinopathy ( PDR ) patients, it can cause fibrovascular membrane formation, epiretinal membrane fibrosis increased, resulting in traction retinal detachment with further aggravate the condition. The recent research suggests that cytokines promote fibroblast proliferation, movement, adhesion, and secretion of extracellular matrix functions in the diabetic state of the environment changes to profibrogenic state, resulting in the accumulation and fibrosis of extracellular matrix. This paper reviewed the status quo of the correlation between vascular endothelial growth factor and fibrosis-related cytokine.

OBJECTIVETo observe the primary prevention role of Wuling Capsule (WC) on poststroke depression (PSD) patients.
METHODSAcute stroke patients were recruited and randomized into 2 groups by stratification, 55 in each group. All patients received same routine treatment of cardiovascular diseases. Patients in the experimental group additionally took WC (0.33 g each pill), 3 pills per day, three times per day; while those in the control group additionally took placebos, 3 pills per day, three times per day. Two weeks consisted of one therapeutic course. The diagnosis of PSD was performed once every other week. Those in accordance with PSD diagnosis discontinued any drug therapy. Those not in accordance with PSD diagnosis continued the drug therapy for 1-12 therapeutic course(s) (in total of 6 months). If they were still not in accordance with PSD diagnosis, then they discontinued the drug therapy. The morbidity of PSD, the average time of depression occurrence, Hamilton depression rating scale (HAMD) score, and adverse reactions were observed.
RESULTSThe 1-, 3-, and 6-month morbidity of PSD was 8%, 16%, and 34% in the experimental group, while they were 19.6%, 29.4%, and 54.9% in the control group. The occurrence rate was lower in the experimental group than in the control group. Besides, there was statistical difference in the 6-month occurrence rate between the two groups (chi2 = 4.465, P < 0.05). The average time of PSD occurrence was longer in the experimental group than in the control group (14.96 +/- 8.31 weeks vs. 9.36 +/- 6.06 weeks; t=6.762, P < 0.05). The HAMD score at the PSD occurrence was 11.96 +/- 2.14 in the experimental group, lower than that of the control group (14.57 +/- 4.24), showing statistical difference (t=5.641, P < 0.05).
CONCLUSIONWC was superior to the placebos in lowering the incidence of PSD, delaying the occurrence time of PSD, attenuating the depression degree of PSD, and had certain preventive effect on the incidence of PSD.

Objective To analyze the sensitivity of clinical isolates of Candida albicans to flucona- zole,to detect mutations in their ERG11 genes,and to investigate the correlation between ERG11 gene mutation and resistance to fluconazole.Methods Candida albicans was identified from clinical isolates of Candida spp..The sensitivity to fluconazole was detected in vitro by microdilution-basesd method and Rosco tablets method.Three pairs of primers were designed to amplify three fragments of ERG11 gene(483 bps, from 295 bp to777 bp;482bps,from 723 bp to 1204 bp;489 bps,from 1179 bp to 1667 bp)after the extracting of genomic DNA.PCR products were sequenced.Results Eighty clinical isolates of Candida spp.were collected,which included 52 isolates of Candida albicans,all of which were sensitive to flucona- zole.Nineteen mutations were detected in ERG11 gene of 5 fluconazole-sensitive clinical isolates.Of the 19 mutations,14 were samesense mutations,and the remaing 5 missense mutations(T495A,A530C, G640A,A945C and G1609A),resulting in amino acid substitution D116E,K128T,E165K,E266D and V488I,respectively in lanosterol 14 alpha-demethylase.E165K was a novel mutation.Conclusions The clinical isolates of Candida albicans were highly sensitive to fluconazole;E165K and V488I might not lead to the resistance of Candida albicans to fluconazole.

Objective To investigate clinical characteristics of relapsing polychondritis(RP)and to improve early recognition for it.Methods Clinical and laboratory data of 56 patients with RP were analyzed retrospectively.Results Ratio of number of male patients to female ones was 1.2.Age at onset was(46?11)years(ranging from 27 to 71)and average interval between onset and diagnosis was(21? 35)months,(8?6),(16?31)and(29?37)months for patients initial onset with auricle,respiratory tract and joints involved,respectively.Site involved included airway in 40 patients(71.4%),auricle in 32 (57.1%),joints in 32(57.1%),eyes in 27(48.2%),nasal chondritis in 25(44.6%)and inner ear in 13(23.2%).At initial stage of the course,17 patients were misdiagnosed as respiratory infection (30.4%),nine as perichondritis(16.1%),six as pulmonary tuberculosis(10.7%),five as rheumatoid arthritis(8.9%).Seven of 40 patients with airway involvement received metallic stents for their tracheobronchial stenosis.Four patients whose condition never improved after regular therapy all had respiratory involvement.Conclusions Patients of RP with initial onset at non-auricle,non-nasal sites tended to be misdiagnosed.Prevalence of airway involvement was not so low with a poor prognosis in patients of RP.

AIM: To analyze the clinical feature and treatment of endogenous endophthalmitis caused by liver abscess. METHODS: A total of 9 eyes (7 cases) with endogenous endophthalmitis caused by liver abscess in our hospital from 2005 to 2010 were analyzed retrospectively. Microorganism was cultivated with blood or vitreous in all patients.4 eyes were performed vitrectomy. 2 eyes were injected antibiotics in vitreous cavity. 3 eyes were only treated with antibiotics.RESULTS: Two cases (2 eyes) were diagnosed with endophthalmitis firstly, then found liver abscess; 4 eyes were with diabetes mellitus, and 1 eye with abnormal glucose tolerance. Cultivation of microorganism was positive in 6 eyes (67%), including Pneumonia cray-research, Candida albicans and Escherichia coli. 5 eyes had useful vision after treatment, 1 eye had light perception,3 eyes became blindness. CONCLUSION: As an ocular emergency, endogenous endophthalmitis caused by liver abscess can severely damage visual function. Timely consultation, early diagnosis, proper systemic and topical anti-infective and anti-inflammatory treatment are the most effective methods for controlling infection. Vitrectomy with intravitreal antibiotics plays an important role in preserving useful vision function in patients.
