We selected scores for histology and embryology,physiology,biochemistry,pathobiology,pharmacology,paediatrics,and medicine of the first-year(2004),second-year(2003),third-year(2002)students at a medical school as subjects to analyze construction validity using factor analysis.The common factors were selected if their cumulative value above 60%.The result showed that variance percentage explained by each factor was lower,and that the three level structure formed by recall,comprehend and application would not be explained ideally by these scores.The author considered that the examination items should be improved and it was limited for factor analysis method to apply to analyze medical examination items.

Chronic inflammatory demyelinating polyneuropathy (CIDP) with positive anti-contactin-associated protein-1 (Caspr1) antibody is a rare autoimmune antibody mediated peripheral neuropathy. A 62-year-old male patient was reported in this article, whose clinical manifestations were subacute onset, abnormal distal limb motor sensation, and increased cerebrospinal fluid protein level. The patient had a good response to plasma exchange. Electromyography of lower limbs showed that motor involvement was dominant, motor conduction velocity slowed down, compound motor active potential (CMAP) and sensory nerve active potential amplitude decreased, and F wave was not elicited; electromyography of upper limbs without symptoms showed that CMAP amplitude of median nerve decreased, and conduction velocity was normal. There are few reports of anti-Caspr1 positive CIDP in the world. The article summarized the characteristics of the patient and reviewed the relevant literature, in order to improve clinicians′ understanding and diagnosis and treatment ability of the disease.

To explore the effect of Kudiezi injection on renal function in the real world, in order to provide the basis for the clinical medication safety. Patient aged between 18-80 were selected from 18 large hospitals information system (HIS) databases established by clinical research institute for basic traditional Chinese medicine of China academy of Chinese medical sciences. The patients who were treated with Kudiezi injection (24 225 cases) were defined as the exposed group, whereas those who were not treated with Kudiezi injection (14,191 cases) were defined as the non-exposed group. The propensity score method was used to balance the confounding factors. Classic logistic regression, GBM weighted propensity score logistic regression, GBM propensity score weighted logistic regression with covariate and sensitivity analysis were adopted to study the effect of Kudiezi injection on renal function. The results showed no significant difference in the possibility in abnormality in serum creatinine (Scr) (P = 0.940, 0.679, 0.834) and urea nitrogen (BUN) (P = 0, 0.045, 0.164) between both groups. Therefore, the existing data indicated no damage of Kudiezi injection on renal function. Because this study is a retrospective study based on the real world, there may be unknown confounding factors and potential bias. Therefore, further studies shall be conducted to monitor whether Kudiezi injection causes damage on renal function, in order to ensure the clinical medication safety.

Objective To examine the expression of ATP-binding cassette transporter A1(ABCA1)in eukaryotie cells and the effect of arsenic resistance after the transfection of eukaryotic expression vector containing ABCA1 gene.Methods HeLa cells were transfected with the recombinant plasmid by lipofectaonmine 2000 (recombinant plasmid group),empty plasmid and untransfected HeLa cell as the control group.The level of the mRNA was examined by real-time PCR,and the expression of ABCA1 protein wag examined by Western blot,the change of cell survival rate was examined by methyl thiazolyl tetrazolium(MTT)after exposure in a series of arsenic [0(contro1),4,8,16,32,64,128 μmol/L]for 48 hours.Results Expression level of ABCA1 mRNA in recombinant plasmid,empty plasmid and untransfeeted groups was(2.09±0.08)×10-4,(0.09±0.02)×10-4,(0.08±0.02)×10-4,there was a significant difference between the groups(F=1499.23,P<0.01).The level of ABCA1 mRNA in recombinant plasmid group was higher than empty plasmid and untransfected group(all P<0.01).Western blot showed that specific protein straps existed at 254×103 in all the three groups,with a similar size to the ABCA1 protein.The amount of the recombinant plasmid group was higher than the other two groups.MTT shows that arsenic concentration at 4,8,16,32,64,128 μmol/L,the survival rates of recombinant plasmid group was(94.8±0.9)%,(86.5 ± 2.6)%, (77.8 ± 2.0)%, (56.0 ± 2.0)%, (23.8 ± 1.7)%, (18.6 ± 0.6)%, higher than that of empty plasmid group[ (85.3 ± 1.1)%, (78.7 ± 0.6)%, (67.8 ± 2.4)%, (43.2 ± 1.5)%, (14.5 ± 1.3)%, (8.0 ± 0.4)%], the difference of survival rate had a statistical signifieance(t = 18.985,6.689,5.922,9.504,9.481,32.634, all P < 0.01). Conclusions ABCA1 protein is over expressed in HeLa cells after transfect ABCA1 gene. ABCA1 protein increases resistance of arsenic in HeLa cells.

BACKGROUND:Longbie Capsule has satisfactory outcomes in the treatment of osteoarthritis, but its mechanism is stil unclear.
OBJECTIVE:To study the effect of Longbie Capsule on proliferation of bone marrow mesenchymal stem cel s. METHODS:The bone marrow mesenchymal stem cel s from SD rats were separated and expanded by whole adherence culture, then subcultured and confirmed by morphological observation and flow cytometry. Passage 4 cel s were cultured in complete media containing 5 g/L, 1 g/L, 250 mg/L, 50 mg/L, 10 mg/L Longbie Capsule, respectively, for 24 hours. Then, MTT assay was used to detect cel viability.
RESULTS AND CONCLUSION:The primary cel s were adherent cel s characterized by irregular shape, passage 2 cel s were typical y fibrous-shaped, passage 3 cel s grew in long fibrous and swirl-type shape. Passage 4 cel s were strongly positive for CD29 and CD90, positive for CD44, and negative for CD34 and CD45. 5 g/L and 1 g/L Longbie Capsule promoted the proliferation of bone marrow mesenchymal stem cel s. These findings indicate that Longbie Capsule may promote the proliferation and differentiation of bone marrow mesenchymal stem cel s, thereby playing a therapeutic effect on osteoarthritis.

Objective To compare the toxicity of outer membrane vesicles ( OMVs) secreted by Acinetobacter baumannii strains with different drug-resistance spectrums.Methods Four Acinetobacter baumannii strains with different drug-resistance spectrums were collected (strain 33, 3237, B29 and 10), and OMVs produced by these strains were extracted and purified.BCA assay was used to determine the protein concentrations, and RAW264.7 cells were incubated with different concentrations of OMVs for 24 h. Cell viability was measured with CCK-8 assay, and gene expression of tumor necrosis factor-alpha ( TNF-α) , interleukin-6 ( IL-6) , interleukin-1 beta ( IL-1β) , keratinocyte-derived chemokine ( KC) and macrophage inflammatory protein 2 (MIP-2) was assessed by quantitative real-time PCR.One-way ANOVA was used for data analysis.Results According to the result of drug susceptibility test, strain 10 was extensively drug-resistant Acinetobacter baumannii ( XDRAB ) strain, strain B29 was multi-drug resistance Acinetobacter baumannii (MDRAB) strain, while strain 33 and 3237 were non-MDRAB strains.After incubated with different concentrations of OMVs for 24 h, cell viability of RAW264.7 declined with the increase of OMVs concentrations.OMVs released from strain10, B29 and 3237 significantly lowered the cell viability at the concentration of 5 μg/mL, while the cytotoxicity of OMVs released from strain 33 was much weaker, and no remarkable decrease in cell viability was observed even at the concentration of 25 μg/mL.OMVs of all strains induced the release of TNF-α, IL-6, IL-1β, KC and MIP-2 in RAW264.7 cells, and the levels of theses cytokines were increased with the concentration of OMVs.Inflammatory response in cells incubated with OMVs from strain 33 was the weakest, while OMVs from strain 10 induced strongest inflammatory response.KC and MIP-2 levels were significantly higher in RAW264.7 cells incubated with OMVs from strain 10 with a concentration of 5 μg/mL than that incubated with OMVs from other strains ( F=19.094 and 19.032,P<0.05 or <0.01).Conclusions OMVs from Acinetobacter baumannii strains with different drug-resistance spectrums are of different toxicity.OMVs from XDRAB and MDRAB strains have higher toxicities and may induce stronger inflammatory response.

Objective:To analyze the characteristics of clinical manifestation, auxiliary examination and gene mutation of 3-hydroxy-isobutyryl-coenzyme A hydrolase (HIBCH) deficiency to better understand this disease.Methods:The clinical manifestations and genetic results of a patient with HIBCH deficiency were analyzed. The clinical features and genetic characteristics of HIBCH deficiency were summarized based on the literature review.Results:The proband, female, one year and four months old, was admitted to Children′s Hospital Affiliated to Zhengzhou University for “vomiting and diarrhea for 15 days, dyspnea and intermittent convulsions for 13 days after digestive tract infection”. The intelligence was normal, however, the motor development was slightly delayed before onset. Physical examination showed light coma, poor response and insensitivity to light. She also had shortness of breath, weak positive three concave signs and coarse breath sound in both lungs with sputum purrs. In addition, the muscle tension of extremities was increased. Bilateral Brudzinski′s sign, Babinski′s sign and Kernig′s sign were negative. Serum hydroxybutyryl carnitine (C4OH) was increased. Cranial magnetic resonance imaging (MRI) showed atrophy in bilateral cerebral hemispheres and abnormal symmetry signals in bilateral globus pallidus and cerebral peduncle. Novel compound heterozygous variants of HIBCH, c.489T>A (p. C163*) and c.740A>G (p. Y247C), were found in the patient, which respectively inherited from her healthy parents. Her symptoms were relieved after“cocktail”therapy and symptomatic treatment. Literature related to HIBCH deficiency published all around the world was reviewed. As a result, 17 articles, including 24 cases, had been reported. The majority of patients presented with poor feeding, dystonia and progressive motor developmental delay in early infancy. Cranial MRI showed lesions in bilateral basal ganglia. Serum C4OH concentration was elevated. And compound heterozygous or homozygous variants of HIBCH gene were found in patients with HIBCH deficiency.Conclusions:The detection of serum amino acids and acylcarnitine profiles on HIBCH deficiency was relatively specific and it was helpful to make a clear diagnosis by combining with cranial MRI and genetic tests. In this study, a case of HIBCH deficiency was confirmed, which expanded the mutation spectrum of HIBCH gene. Meanwhile, summarizing the clinical and genetic characteristics of cases reported improved understanding of HIBCH deficiency.
