[Objective] To observe the regulatory effect of Huangqi Injection (HI) on immune function of patients after chemotherapy (CT). [Methods] Thirty-four patients confirmed as acute myelogenous leukemia (AML) received two cycles of CT. During the 1st cycle, the patients were only treated with DA (daunomycin + arabinoside) regimen; in the 2nd cycle, intravenous injection of 20 mL of HI, qd for 2 weeks was added. The effect of CT on myelosuppression and immune function of the patients was observed. [Results] Immunosuppressive manifestations such as myelosuppression, fatigue, spontaneous sweating, impaired appetite, lassitude were found after the 1st cycle of CT, and peripheral immunoglobulin A (IgA), IgG, IgM and complements C3 levels were also decreased (P

OBJECTIVE To investigate the trend of distribution and drug resistance of clinical isolates of Enterobacter cloacae during the last three years in our hospital. METHODS Strains collected from daily specimens were identified and drug resistantce with SENSITITRE bacteria analysis system. RESULTS The most strains were isolated from samples of sputum,urine,nad other excretion. The drug resistance rates to imipenem and cefepime were less than 32%. Cefoxitin,ampicillin and cefazolin were ineffective to contralE. cloacae. The drug resistance rates to penicillins,cephalosporins,chloramphenicol and aminoglycoside antibiotics increased more than 20% in last three years. CONCLUSIONS E. cloacae is multiple-resistant to antibiotics and displays higher levels of antibiotic resistance. It is suggested that antibiotics be used reasonably under the guidance of antibiotic susceptibility testing.

Objective To investigate the reliable parameters of the efficacy of CRT on patients with CHF evaluated by 3D-STI. Methods Thirty-six patients with CHF were performed by three-dimensional speckle tracking imaging (3D-STI) before and at one week, one month and three months after CRT, respectively. The left ventricular end systolic volume (3D-LVESV), the left ventricular ejection fraction (3D-LVEF) and the left ventricular dys-synchrony parameters which include the standard deviation of time to peak (AT-SD) and the maximum difference of time to peak (AT-Dif) of radial strain, circumferential strain and area tracking in the 16 left ventricular segments and the changes of 3D-LVESV, 3D-LVEF (ΔLVEF), AT-SD (ΔAT-SD) and AT-Dif (ΔAT-Dif) at 3 months after CRT were determined. Forty normal volunteers as the controls were performed 3D-STI only once. Results AT-SD, AT-Dif of three kinds of strain, LVESV of the patients in both effective and non-effective groups were significantly higher than those in the control group before CRT (P < 0.05). AT-SD, AT-Dif of three kinds of strain in the CRT effective group were significantly higher than those in the CRT non-effective group , whereas 3D-LVESV and 3D-LVEF were not significantly different between these two groups before CRT. For the CRT effective group, one week after CRT, all of the left ventricular dyssynchrony parameters were decreased (P < 0.05, respectively). For the CRT non-effective group, the changes of total assessment parameters after CRT were not significant (P > 0.05). ΔAT-SD and ΔAT-Dif were negatively correlated with ΔLVEF. Conclusion 3D-STI can efficiently evaluate the short-term efficacy of CRT , and the area tracking is a reliable parameter to predict and assess CRT efficacy.

This article was aimed to study the characteristics of intestinal cancer by traditional Chinese medicine (TCM) based on the scale-free network analysis method. History information of 145 hospitalized cases from 2008 to 2011 was collected from the Oncology Department, Guang A nmen Hospital, in the clinical collection system. The rule of medication in the treatment of intestinal cancer by TCM was explored by scale-free network analysis method from several aspects, such as effects, classification and compatibility relations. The analysis results of 145 intestinal cancer cases showed that strengthening the body resistance was the main treatment principle. Si-Jun-Zi (SJZ) decoc-tion was used with the highest frequency. In the prescription design, qi-supplementing herbs were the most. The heat-clearing, dampness-eliminating, qi-regulating, blood-activating and stasis-removing, food stagnation removing and phlegm-removing herbs were also used frequently. The TCM treatment and syndrome differentiation will be changed due to the treatment and disease stages. It was concluded that scale-free network analysis method is able to relatively show the TCM treatment rule of intestinal cancer quantificationally and intuitively.

Objective To provide guidance for reconstructing the sensation of the anterolateral thigh flap (ALTF) used to repair extensive soft tissue defects in heel. Methods Choose 7 adult male corpses, take the nerval samples respectively from the lateral femoral cutaneous nerve (LFCN) 5cm below the anterior superior iliac spine (ASIS) and the initial segment of the medial caleaneal nerve (MCN) and the lateral calcaneal nerve (LCN), fixed, dewatered gradiendy, embedded, located, and made them into semithin sections, dyed with toluidine blue. The pictures were taken by a medicine figure imaging analysis system named MOTICMED 6.0, observe the nerves's sectional morphous, the quantity and distribution of their nerve fiber bundles, count the quantity of nerve fibers and determine the density of them. Use Photoshop 7.0 version precinct software for measuring and calculating the area of the nerve fiber bundles and the Photoshop grid function was used to measure the density of the nerve fibers. Results In our cross-section study, the median number of nerve bunches in LFCN, MCN and LCN1, was 4, 3 and 4, respectively. The median number of nerve fibers' area was 114.8 um2, 126.92 um2 and 102.76um2, respectively. The median number of nerve fibers' density was 11.43/um2, 6.47/um2 and 10.08/um2, respectively. The median number of nerve fibers was 987, 862 and 570, respectively. Conclusion The MCN and the LCN1 are ideal cutaneous nerves to suture with LFCN in the ALTF used to repair widespread soft tissue defects in heel because they have similar histomorphological characteristics with the LFCN.

To obtain the P8 protein of Rice gall dwarf virus (RGDV) with biological activity, its outer coat protein gene S8 was expressed in Spodoptera frugiperda (Sf9) insect cells using the baculovirus expression system. The S8 gene was subcloned into the pFastBacTM1 vector, to produce the recombinant baculovirus transfer vector pFB-S8. After transformation, pFB-S8 was introduced into the competent cells (E. coli DH10Bac) containing a shuttle vector, Bacmid, generating the recombinant bacmid rbpFB-S8. After being infected by recombinant baculovirus rvpFB-S8 at different multiplicities of infection, Sf9 cells were collected at different times and analyzed by SDS-PAGE, Western blotting and immunofluorescence microscopy. The expression level of the P8 protein was highest between 48-72 h after transfection of Sf9 cells. Immunofluorescence microscopy showed that P8 protein of RGDV formed punctate structures in the cytoplasm of Sf9 cells.

OBJECTIVE:To provide the clinical departments with a reference for promoting rational drug use. METHODS:The inpatient prescriptions given by orthopaedics and burn departments from Jun. to Dec. 2013 were selected randomly. The number of the selected prescriptions by each department accounted for 2% of the total prescriptions given by the corresponding department in that month,including 4 921 cases by orthopaedics department and 1 391 cases by burn department. Statistical analysis of irrational prescriptions was made according to Chinese Pharmacopoeia,New Materia Medica,the package insert, and other relevant references. RESULTS:1 821 prescriptions given by orthopaedics department and 378 by burn department were found to be irrational,accounting for 37.00% and 27.17% respectively. The reasons of irrationality mainly included im-proper compatibility,improper route of administration,contraindication in and use with caution by the elderly and children,re-peated drug use,improper drug combination etc. CONCLUSIONS:The system of prescription review should be strengthened, and clinical staff training system and pharmaceatical knowledge information platform are established to promote rational use of drugs.

AIM: To investigate the behaviour of 3T3 fibroblast and macrophage co-culture on blood fibrin clot or adipose tissue with recombinant basic fibroblast growth factor (rhbFGF). METHODS: MTT method, inverted contrast microscopy, Giemsa staining as well as scanning electron microscope were used in the present study. RESULTS: The effect of rhbFGF on co-culture of 3T3 fibroblast and mouse macrophage on blood fibrin clot in low-serum DMEM with rhbFGF were monitored, and 3T3 fibroblast and macrophage growed well on the blood fibrin blot in low-serum DMEM with rhbFGF. CONCLUSION: The blood fibrin clot, with its low immunogenicity, could be used as a bionic support for three-dimensional tissue culture, and also a physiological carrier to distribute the growth factor rhbFGF for the cells.

This article was aimed to study medication rules of traditional Chinese medicine (TCM) in the treatment of gastric cancer. The history information of 111 hospitalized cases from 2008 to 2011 was collected from the Department of Oncology of Guang'anmen Hospital with the clinical collection system. The medication rules in the treatment of gastric cancer by TCM were explored by the scale-free network analysis from several aspects, such as effects, classifications and compatibility relations of Chinese medicine. The analysis result of 111 gastric cancer cases showed that strengthening the body resistance was the main treatment principle. Liujunzi decoction was the most frequently used prescription. In TCM compatibility, deficiency-nourishing herbs were the main ingredients, especiallyqi-supplementing herbs which take the first place in the prescription. And the heat-reducing herbs, dampness-eliminating herbs, blood-activating and stasis-eliminating herbs, food stagnation resolving herbs and qi regulation herbs were also used in the combination. Core herbs in the prescription for the treatment of gastric cancer were Tuckahoe, Codonopsis pilosula, Astragalus root, Pericarpium Citri Reticulatae, Fructus Aurantii, Nidus Vespae and etc. TCM treatment, syndrome differentiation and medication are varied according to different therapeutic stages and disease stages. The result showed that scale-free network analysis had certain significance in the understanding of medication rules of TCM treatment of gastric cancer.

Objective: To investigate the effect of allogeneic red blood cell transfusion on T lymphocyte subsets and natural killer (NK) cells in peripheral blood of patients with gastric cancer during perioperative period. Methods: 50 patients with gastric cancer in our hospital from January 2017 to December 2017 were randomly divided into control group (n=25) and observation group (n=25). Perioperative allogeneic erythrocyte transfusion was performed in the observation group, while no allogeneic erythrocyte transfusion was performed in the control group. Blood samples were taken from two groups before and after operation 3 d, and serum T lymphocyte subsets (CD3⁺, CD4⁺, CD8⁺, CD4⁺ /CD8⁺ ) and NK cell levels were measured. T cell subsets and NK cell levels of patients in observation group, control group and observation group at different clinical stages before and after operation were counted. According to blood transfusion volume, the patients in the observation group were divided into <4 U group and <4 U group. T cell subsets and NK cell levels before and after operation were compared between the two groups. Results: There was no significant difference in CD3⁺, CD4⁺, CD8⁺, CD4⁺ /CD8⁺, NK cells between the two groups before operation (P>0.05). The levels of CD3⁺, CD4⁺, CD4⁺ /CD8⁺, NK cells in the two groups after operation were lower than those before operation and CD8⁺ levels were higher than those before operation. The levels of CD3⁺, CD4⁺, CD4⁺ /CD8⁺, NK cells in the observation group were lower than those in the control group, and the levels of CD8⁺ in the observation group were higher than those in the control group (P<0.05). The levels of CD3⁺, CD4⁺, CD8⁺, CD4⁺ /CD8⁺, NK cells in patients with stage Ⅰ-Ⅱ and stage Ⅲ-Ⅳ had no significant difference before operation (P>0.05). After operation, the levels of CD3⁺, CD4⁺, CD4⁺ /CD8⁺, NK cells in the two groups were lower and CD8⁺ levels were higher than those before operation. The levels of CD3⁺, CD4⁺, CD4⁺ /CD8⁺, NK cells in stage Ⅰ-Ⅱ patients were higher than those in stage Ⅲ-Ⅳ patients, and CD8⁺ levels were lower than those in stage Ⅲ-Ⅳ patients (P< 0.05); There was no significant difference in the levels of CD3⁺, CD4⁺, CD8⁺, CD4⁺ /CD8⁺, NK cells between the <4 U group and <4 U group before operation (P>0.05). After operation, the levels of CD8⁺ in the two groups were higher than those before operation, while the levels of CD3⁺, CD4⁺, CD4⁺ /CD8⁺, NK cells were lower than those before operation; The levels of CD3⁺, CD4⁺, CD4⁺ /CD8⁺, NK cells in the <4 U group were higher than those in >4 U group, and CD8⁺ levels were lower than those in >4 U group (P<0.05). Conclusions Perioperative allogeneic red blood cell transfusion can affect T cell subsets and NK cell content in peripheral blood of patients with gastric cancer, and there are some differences in the effects of different clinical stages of gastric cancer patients, which can cause the suppression of cellular immune function.
