Objective To investigate the clinical effect of glutamine on parenteral alimentation in patients with severe craniocerebral injury in ICU. Methods 120 patients with severe brain injury in our hospital from November 2013 to November 2014 were selected as the research object.According to the random number table method, the 120 patients were divided into experimental group and control group, 60 cases in each group.The patients in the experimental group received glutamine parenteral nutrition support, while the control group received conventional parenteral nutritional support.The serum total protein, albumin, the complications and malnutrition-inflammation score(MIS) scores of the two groups were compared.Results The serum total protein and serum albumin levels of the experimental group post-treatment were significant higher than those in the control group (P<0.001).The complication rate in the experimental group was 15.0%, significantly lower than the control group of 55.0%(χ2 =21.099,P<0.001).The patients of normal MIS score in the experimental group were obviously superior to the control group ( 70.0% vs.33.3%, χ2 =16.151, P <0.001 ). Conclusion Adding glutamine to parenteral nutrition support therapy in the treatment of patients with severe craniocerebral injury can effectively improve the nutritional status after operation and strengthen nutrition support.

Objective To study the expression of RhoA and C-myc in gastric carcinoma , and to discuss the action in infiltration and metastasis of gastric carcinoma as well as their dependability. Methods RhoA protein expression and C-myc protein expression were detected by immunohistochemical method in 46 cases of gastric carcinoma and 20 cases of normal tissues..RhoA protein expression was compared with clinical pathologic parameters as related to C-myc. Results The positive rate of RhoA,C-myc were significantly higher in gastric carcinoma than in normal tissue (P < 0.05). The expression of RhoA and C-myc were associated with the loss of tumor differentiation, lymph node metastasis and deep invasion (P<0.05). There was a significant correlation between RhoA and C-myc (r=0.62, P<0.05). Conclusions The data suggests that the expression level of RhoA protein was closely related to biological behavior of gastric carcinoma. RhoA and C-myc were possibly both correlated with the infiltration and metastasis of gastric carcinoma.

An analytical method of on-line injection technique including on-line dilution and on-line preconcentration with inductively coupled plasma mass spectrometry ( ICP-MS ) was established for the determination of trace metals in seawater, such as Cr, Mo, Cu, Pb, Zn, Cd, Fe, Mn, Ni, V, Co. This method could automatically make standard curves and match matrix, and by the on-line dilution and preconcentration modes, 11 trace metals could be analyzed directly. With high-level automation, CASS-5 and NASS-6 seawater standard samples were analyzed accurately by this method. The recovery of metals in seawater sample addition was between 80% and 115%. The method quantitation limits (μg/L ) of theses metals in seawater were 0. 06(Cr), 0. 06(Mo), 0. 01(Cu), 0. 005(Pb), 0. 01(Zn), 0. 006(Cd), 0. 03 (Fe), 0. 02(Mn), 0. 01(Ni), 0. 01(V), and 0. 01 (Co), respectively. This method was applied to analyze seawater samples of various salinities in Zhejiang coast, and the analysis results were consistent with results of conventional atomic absorption method.

OBJECTIVE: To analyze the indications of the therapies for rheumatoid arthritis (RA) with neural network model analysis. METHODS: Three hundred and ninety-seven patients were included in the clinical trial from 9 clinical centers. They were randomly divided into Western medicine (WM) treated group, 194 cases; and traditional Chinese herbal medicine (CM) treated group, 203 cases. A complete physical examination and 18 common clinical manifestations were prepared before the randomization and after the treatment. The WM therapy included voltaren extended action tablet, methotrexate and sulfasalazine. The CM therapy included Glucosidorum Tripterygii Totorum Tablet and syndrome differentiation treatment. The American College of Rheumatology 20 (ACR20) was taken as efficacy evaluation. All data were analyzed on SAS 8.2 statistical package. The relationships between each variable and efficacy were analyzed, and the variables with P<0.2 were included for the data mining analysis with neural network model. All data were classified into training set (75%) and verification set (25%) for further verification on the data-mining model. RESULTS: Eighteen variables in CM and 24 variables in WM were included in the data-mining model. In CM, morning stiffness, swollen joint number, peripheral immunoglobulin M (IgM) level, tenderness joint number, tenderness, rheumatoid factor (RF), C-reactive protein (CRP) and joint pain were positively related to the efficacy, and disease duration and more urination at night negatively related to the efficacy. In WM, erythrocyte sedimentation rate (ESR), weak waist, white fur in tongue, joint pain, joint stiffness and swollen joint were positively related to the efficacy, and yellow fur in tongue, red tongue, white blood negatively related to the efficacy. In the analysis with the neural network model in the patients of verification set, the predictive response rates of 20% patients would be 100% and 90% in the treatment with CM and WM, respectively. CONCLUSION: Neural network model analysis, based on the full clinical trial data with collection of both traditional Chinese medicine and modern medicine diagnostic information, shows a good predictive role for the information in the efficacy in rheumatoid arthritis.

OBJECTIVE: To evaluate the correlations between clinical symptoms and treatment efficacy in patients with rheumatoid arthritis (RA). METHODS: Four hundred and thirteen patients were included in the clinical trial from 9 clinical centers. They were randomly divided into Western medicine-treated group with 204 cases and Chinese herbal drug-treated group with 209 cases. Eighteen clinical symptoms were evaluated before and after treatment. The Western medicine therapy included voltaren extended release tablets, methotrexate and sulfasalazine. The Chinese herbal drug therapy included glucosidorum Tripterygii totorum tablets and Yishen Juanbi Tablets combined with treatment based on syndrome differentiation. The American College of Rheumatology 20 (ACR20) was used as efficacy evaluation criteria. RESULTS: In the Chinese herbal drug-treated group, clinical symptoms such as arthralgia and tenderness of joints were positively correlated with the efficacy after 12-week treatment, while frequent urination at night was negatively correlated. In the same group, tenderness of joints and fever were positively correlated with the efficacy after 24-week treatment, while deep-colored and turbid urine was negatively correlated. In the Western medicine-treated group, tenderness of joints and thirst were positively correlated with the efficacy after 12-week treatment, while vertigo was negatively correlated. And in the same group, tenderness of joints was positively correlated with the efficacy after 24-week treatment, while heaviness of limbs was negatively correlated to the efficacy. The statistical results showed that the treatment efficacy was improved when the correlated symptoms were included in the indications. CONCLUSION: The treatment efficacy of RA is correlated with some symptoms, so further studies should proceed on these correlations in order to achieve better treatment outcome.

It is well known that puerarin possesses protective activity on neurodegenerative diseases. However, the exact path way involved in the protective effect of puerarin on MPP+ -induced cell death is unclear. In this study, we focused on mitochondria im pairment in the apoptotic process of MPP+ -elicited SH-SY5Y cells and detected the protection of puerarin. As evidenced by Trypan blue assay, the cell viability was significantly decreased by 1 mmol x L(-1) MPP+, but reversed by different concentrations puerarin pre treatment. Flow cytometer analysis revealed that MPP+ -induced SH-SY5Y cells apoptosis and arrested the cells in G2/M phase, where as puerarin pretreatment concentration dependently reversed the apoptosis ratio. In addition to the apoptosis ratio, 50.0 micromol x L(-1) puerarin pretreatment even altered the MPP+ -induced G2/M phase arrest. JC-1 assay suggested that MPP+ significantly opened MMP of the SH-SYSY cells; pretreatment with puerarin attenuated the deterioration of the MMP. Both ELISA and Western blotting showed that puerarin prevented the release of cytochrome c from the mitochondrial interior to the cystol elicited by MPP+. DNA ladder showed that typical DNA ladder was present in the MPP+ -induced SH-SY5Y cells. Additionally, MPP+ enhanced caspase-9 and caspase-3 ac tivity, respectively, while not caspase-8. However,the enhancement was concentration dependently blocked by puerarin pretreatment. Taken together, puerarin can modulate mitochondrial membrane potential and inhibit the cytochrome c releasing-caspase cascade to pre vent MPP+ -induced cell injury.

Background/Aims: This study aimed to investigate the biological function and regulatory mechanism of TCN1 in colorectal cancer (CRC). Methods: We studied the biological function of TCN1 by performing gain-of-function and loss-offunction analyses in HCT116 cell lines; examined the effects of TCN1 on the proliferation, apoptosis, and invasion of CRC cells; and determined potential molecular mechanisms using HCT116 and SW480 CRC lines and mouse xenotransplantation models. Tumor xenograft and colonization assays were performed to detect the tumorigenicity and metastatic foci of cells in vivo. Results: TCN1 knockdown attenuated CRC cell proliferation and invasion and promoted cell apoptosis. Overexpression of TCN1 yielded the opposite effects. In addition, TCN1-knockdown HCT116 cells failed to form metastatic foci in the peritoneum after intravenous injection. Molecular mechanism analyses showed that TCN1 interacted with integrin subunit β4 (ITGB4) to positively regulate the expression of ITGB4. TCN1 knockdown promoted the degradation of ITGB4 and increased the instability of ITGB4 and filamin A. Downregulation of ITGB4 at the protein level resulted in the disassociation of the ITGB4/plectin complex, leading to cytoskeletal damage. Conclusions TCN1 might play an oncogenic role in CRC by regulating the ITGB4 signaling pathway.

Objective To evaluate the clinical performance of chemiluminescent immunoassay (CLIA) on anti-nuclear antibody(ANA) specific autoantibodies testing.Methods A multi-center clinical study A total of 811 Sera samples were collected from 6 collaborating hospitals during the period of April to July 2016, and tested with CLIA and line immunoassay (LIA) in parallel for autoantibodies to ribonucleoprotein(RNP), smith antigen(Sm), SSA/Ro60,SSB/La, centromere protein B(CENPB), double-stranded DNA(dsDNA), nucleosome(Nuc), and ribosome P protein(Rib-P).The positive rate,specificity and qualitative coincidence rate for each antibody between CLIA and LIA methods were analyzed.All discrepant samples for systemic lupus erythematosus (SLE) highly specific autoantibodies (including anti-Sm, dsDNA, Nuc and Rib-P) were retested by enzyme linked immunosorbent assay (ELISA) and further analyzed with SLE disease cohort using McNemar test.Results The positive rate and specificity of CLIA and LIA for antibodies to ANA specific antigens were comparable.Excellent qualitative coincidence were found between CLIA and LIA for the detection of anti-RNP, SSA/Ro60, SSB/La and CENPB (Kappa>0.75), while the coincidence rate foranti-Sm, dsDNA, Nuc and Rib-P detection were moderate (0.4
