Objective To evaluate the quality status of recombinant human interferon α1b injection and find out some quality problems.Methods Totally 31 batches of recombinant human interferon α1b for injection and 11 batches of recombinant human interferon α1b injection from two enterprises were examined according to Chinese Pharmacopoeia Volume Ⅲ (2010),and the quality status of recombinant human interferon α1b injection was evaluated by statistical analysis of the results.Results All 42 batches of samples were qualified.The production process of each enterprise was steady.Conclusion At present the quality of recombinant human interferon αlb injection is generally good.The current standards are feasible,but the specified standard of osmolality needs to be improved.

Chinese medicine pairs (CMP) are specific compatibility with traditional Chinese medicine (TCM) theory as principle, which was formed on basis of effect and treatment theory of TCM. The compatibility of CMP can enhance the effect, or reduce the toxicity. So, compatibility effects of CMP were studied from different pharmacology levels including animals, tissues and organs, cell and molecular levels, their synergy and compatibility attenuation were also evaluated with monomer component-component (group) compatibility-single herb-CMP-formulae as the main line, and the action mechanisms were investigated, all of which can provide scientific basis for the clinical applications of CMP and creation of TCM new drugs.

Objective To determine the expression of membrane-bound B lymphocyte stimulator (BLyS) protein and its mRNA in vitro of peripheral blood mononuclear cells (PBMCs) from individuals with systemic lupus erythematosus (SLE),and to investigate the role of interferon-?(IFN-?) on the expression of BLyS.Methods PBMCs were obtained from 25 SLE patients (mean age of 31+14) and 20 healthy volunteers (mean age of 28?10).They were randomized into IFN-?(5 ng/ml) group and control group.PBMCs were col- lected at 0,6,12 and 24 h for BLyS mRNA assessment using semi-quantitative reverse transcription-PCR (RT-PCR).PBMCs were also collected at 72 h for membrane-bound BLyS protein detection using flow cy- tometry (FACS) and direct immunofluorescence.Results①The expression of BLyS mRNA and membrane- bound protein in PBMCs was significantly higher in individuals with SLE compared with healthy controls (P＜0.05);②IFN-?enhanced BLyS mRNA expression in PBMCs in both healthy controls and SLE patients,with the greatest effect at 6 h (stimulated vs unstimulated,0.42?0.19 vs 0.25?0.14,P＜0.01;0.59?0.28 vs 0.44?0.21,P＜0.01 );③IFN-?also increased the expression of membrane-bound BLyS protein in both healthy con- trols and individuals with SLE (FACs,mean fluorescence intensity,4.5+3.0 vs 3.7~2.6,P

The FTIR method was used to investigate the correlation of bacteria in the contaminated drug and the environmental microbes in the clean room for pharmaceutical microbial test. The similarity of bacteria in the contaminated drug and environmental microbes was compared by critical hit value method and cluster analysis method. This constructed the FTIR spectra library of clean room environmental microbe, and determined the criterion to promptly judge if the bacteria isolated from pharmaceuticals were contaminated by environment or not, hence the exactness of "one-off report" of sterile test result can be guaranteed, and can be used for the dynamic monitoring of environmental bacteria of clean room. The method is proven to be simple, accurate and rapid, and can be easily spread to the pharmaceutical microbial control.

Objective To investigate the effect of vascular endothelial growth factor (VEGF) on the differentiation, formation and function of the dendritic cell (DC) in peripheral blood of patients with oral squamous cell carcinoma (OSCC).Methods Flow cytometry was used to detect the number of DC in peripheral blood of 81 patients with OSCC, and ELISA applied to test serum VEGF concentration the OSCC patients, and immunohistochemistry used to observe the expression of VEGF in primary foei of 57 patients with OSCC.DC from CD-14 peripheral blood mononuclear cells were cultured with VEGF165 in vitro to investigate the cytokine's effect on DC.Results In comparison with controls[(325.70±117.54) ng/L], the level of serum VEGF [(764.33±263.64) ng/L] was significantly increased (P < 0.01) and the DC numbers was significantly decreased (P < 0.01) in patients with OSCC.There was a negative correlation between serum VEGF concentration and the level of DC (P < 0.01).The expression of VEGF in primary focus was positively correlated with serum VEGF concentration, but was negatively correlated with the level of peripheral blood DC (P <0.01).DC cultured in vitro with VEGF165 decreased the expression of CD-1a, CD-40,CD-80, CD-86, CD-83, HLA-DR, and revealed a lower ability of stimulating T lymphocyte proliferation but a higher ability of uptake, compared to controls.Conclusions The overexpressed VEGF in patients with OSCC might be one of the important reasons for blocking the differentiation and maturation of DC.

Objective To investigate the effect of in-hospital comprehensive rehabilitation training schizophrene's cognitive function.Methods 80 schizophrenic patients were randomly divided into study group (n=40)and control group(n=40).Both groups received conventional treatment and care,the study group also received in-hospital comprehensive rehabilitation training such as life skills training,medication management skills training,vocational skills training and social communication traning for 12 weeks.Their cognitive function was measured with Wechsler Adult Memor(Revised)(WMS-RC),Positive and Negative Symptom Scale(PANSS),Nurses'Observation Scale for Inpatient Evaluation(NOSIE)before and after the training,respectively,and changes in cognitive function were compared.Results There was no statistically significance in WMS-RC,PANss,NOSIE scores between the study group and the cantrol group before training.There was statistically significance in WMS-RC,Calculation scores(15.09±1.57 vs 13.36±1.55,t=3.005.P=0.04),dtgit span scores(13.32±1.68 vs 12.08±1.79,t=3.124,P=0.003),number sign(8.17±2.21 vs 8.24±1.41,t=3.212,P=0.003),total sares(32.79±6.14 vs 29.78±4.58,t=3.412,P=0.001),memory quotient sares(116.25±3.94 vs 112.72±3.07,t=4.382,P=0.000)between the two groups ccfter 12 weeks;There was statistically signifieamce in PANSS,NOSIE scores between the study group and the control group after training 12 weeks.Conclusions In-hospital comprehensive rehabilitation training can improve schizophrene's cognitive function.

OBJECTIVETo study the difference in clinico-pathological features between IgA nephropathy (IgAN) and Henoch-Schonlein purpura nephritis (HSPN) in children.

METHODSThe medical data of 103 children with HSPN and 61 children with IgAN were retrospectively studied.

RESULTSThere were no significant differences in age, sex and disease course between the HSPN and IgAN groups (P>0.05). Clinical classification demonstrated that more severe conditions were found in the IgAN group than in the HSPN group and gross hematuria was more common in the IgAN group (P<0.05). Serum creatinine and cholesterol levels were higher in the IgAN group than in the HSPN group (P<0.05). Fibrinogen-related antigen deposition was more common in the HSPN group, while complement 3(C3) deposition was more common in the IgAN group. Interstitial fibrosis, tubular casts and tubular inflammatory infiltration were also more common in the IgAN group (P<0.05).

CONCLUSIONSSignificant clinico-pathological differences can be found between HSPN and IgAN in children, and these differences do not support a one disease entity hypothesis.

OBJECTIVETo investigate the significance of serum cholesterol and fibrinogen (Fib) in evaluating the risk of glomerulosclerosis in children with nephrotic syndrome.

METHODSSixty-three children with primary nephrotic syndrome were divided into two groups according to their pathological types: minimal change glomerulopathy (MCG) (n=39) and focal segmental glomerulosclerosis (FSGS) groups (n=24). Serum levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), non-HDL-C and Fib and 24-hour urinary protein excretion were retrospectively analyzed.

RESULTSSerum levels of TC, non-HDL-C, and LDL-C were significantly higher in the FSGS group than in the MCG group (P<0.05), but there were no significant differences in HDL-C, Fib and 24-hour urinary protein excretion between the two groups (P>0.05). According to the results of logistic regression analysis, high levels of LDL-C, non-HDL-C and TC were risk factors for FSGS (P<0.05). In patients whose proteinuria did not disappear after taking enough glucocorticoid for 4 weeks, the level of non-HDL-C was significantly higher in the FSGS group than in the MCG group (P<0.05); there were no significant differences in TC, LDL-C, HDL-C, and Fib between the MCG and FSGS groups (P>0.05).

CONCLUSIONSSerum cholesterol, especially non-LDL-C, is of great significance in evaluating the risk of glomerulosclerosis in children with nephrotic syndrome. There is no sufficient evidence to support serum Fib as a marker for predicting glomerulosclerosis in these children.
