ABSTRACT

Objective:To explore the medication rules of Professor Wang Pei in the treatment of colon cancer.Methods:The medical records of Professor Wang Pei's outpatient treatment for colon cancer were collected, entered into the Traditional Chinese Medicine Inheritance Computing Platform V3.0, and the laws of the prescription's nature, flavor, meridian, drug frequency, drug combination, association rules, and cluster analysis were explored.Results:A total of 65 prescriptions were collected, including 150 Chinese materia medica. The medicinal properties of these Chinese materia medica are mainly warm, cold and flat, the tastes were mainly sweet, bitter and pungent, and the meridians were mainly liver, spleen and kidney meridians. Dampness category and blood circulation promoting and blood stasis category were mainly used, and the most frequently used drugs include Poria, Polyporus, Scutellariae Barbatae Herba, Astragali Radix, Curcumae Rhizoma, and the pairs of Polyporus- Poria, Astragali Radix- Astragali Radix Praeparata cum Melle, Scutellariae Barbatae Herba- Curcumae Rhizoma. Twenty nine high-related drug pairs were obtained from association rules, including Polyporus- Astragali Radix Praeparata cum Melle- Astragali Radix, Poria- Scutellariae Barbatae Herba- Polyporus, Scutellariae Barbatae Herba- Curcumae Rhizoma- Polyporus. The cluster analysis showed the combination of 6 types of medicines mainly focuses on strengthening the spleen and removing dampness, nourishing qi and promoting blood, clearing heat and detoxifying, and astringing the intestines to stop bleeding. Conclusion:Professor Wang Pei mostly discusses the treatment of colon cancer from "spleen dampness, rectification deficiency, heat toxin, blood stasis, bleeding", and the treatment is "invigorating the spleen and removing dampness, invigorating Qi and strengthening the body, clearing away heat and detoxifying, promoting blood circulation and removing blood stasis, and astringent intestines to stop bleeding", which is in line with the thought of Traditional Chinese Medicine treatment of tumors, strengthening the righteousness and eliminating pathogenic factors, and and can be used for clinical reference.

ABSTRACT

Objective To investigate and analyze the prevalence rate as well as antibiotics use in this hospital and to improve the awareness of the hospital infection administration for the medical staff .Methods The hospital infection prevalence rate in hospital and the risk factors were analyzed by prevalence survey and bed-side and case records investigation .Results In all 320 patients sur-veyed ,25 patients were diagnosed with hospital infection and the rate was 7 .81% ;27 cases of hospital infection was reported and the cases prevalence rate was 8 .44% .The main infection site was respiratory tract and it accounted for 48 .14% ,moreover ,the in-tensive care unit ,urology ,and neurology were the high incidence departments .The day of usage rate of antimicrobial drug was 62 .50% ,prevention of drug use was 46 .50% ,a kind drug use was 74 .00% ,and the two kind drug uses was 22 .00% .The positive rate of hospital infection pathogenic detection was 46 .87% .Hospital infection rate was related to the age ,urinary tract intubation , and ventilator factors .Conclusion Hospital infection administration should be strengthened to reduce invasive procedures for key depart-ments and focus groups ,meanwhile ,the rational application of antibiotics should be regulated to reduce hospital infection rates .

ABSTRACT

BACKGROUND:Tracheal injury suture and the development of a new tracheal prosthesis all need to understand the tensile mechanical properties of tracheal cartilage.so as to repair and rebuild tracheal function.Previous researches on the biomechanics of artificial trachea are many reported.while the biomechanics of human tracheal cartilage is reported less.OBJECTIVE:To investigate the mechanical properties of tracheal cartilage using one-dimensional tensile test method.METHODS:Two fresh cadaver specimens of normal human trachea.with the informed consents of their families.were involved.The specimens were thaw at room temperature,and then tracheal cartilage specimens were cut using scalpel into 20 samples at the length of 25 mm,width 5 mm,thickness 1.8-2.2 mm.The 20 tracheal cartilage samples were subjected to one-dimensional tensile test with Shimadzu electronic universal testing machine Japan,at the tensile test speed of 5 mm/min.The tensile maximum load,maximum displacement,maximum stress,maximum strain,elastic modulus and stress-strain curve of the specimens were observed.RESULTS AND CONCLUSION:The maximum load of human cadaver tracheal cartilage was(60 946±10.377)N,maximumdisplacementwas(1.973±0.159)mm,maximum stresswas(6.229±1.125)Mpa,maximum strainwas(32.825±2.776)%.Tracheal cartilage stress-strain curves was changed along with the index,the initial low slope of the curye was due to the direction of imposed tension was similar with the arrangement of collagen structure,the steep slope represented the tensile strength of collagen.To describe the tracheal cartilage stress-strain relationship in a one-dimensional tension,15 stress-strain data of the tracheal cartilage experimental data adopted polynomial by the least square fitting method,to obtain stress(δ)-strain(ε)relationship forrnula:σ(ε)=-0.111 3e~5+1.602 1e~4-7.821 6e~3+17.995 1e~2+3.624e.It is indicated that tracheal cartilage has a strong capacity to bear Joad and resist deformation,reflecting their viscoelastic mechanical properties of both flexibility and viscosity,supporting that the mechanical properties of cartilage is positively related to cartilage collagen content.

ABSTRACT

Objective To study the relationship between serum leptin and fibrosis in chronic hepatitis B incorporate alcoholic liver disease(CHB + ALD) patients.Methods Select 17 male patients with CHB+ALD,15 male patients with liver cirrhosis(LC) ,19 male patients with chronic hepatitis B(CHB) and 12 male healthy persons as normal control(NC).Serum leptin is detected by ELISA in 63 patients.Serum levels of fibrosis markers(HA,LN,PC HI ,IV-C) are determined at the same time.Results Serum leptin level in CHB +ALD are significantly higher than those of the NC(6.79±24.12) μg/L vs (4.27±7.18 ) μg/L (P<0.05).There is no significant difference between patients with CHB and the NC.The four fibrosis markers in CHB + ALD patients are significantly higher than that of men both in the CHB and the NC.There are significant correlations between both serum leptin level and quadrinomial fibrosis markers(P<0.05 or P<0.01 ).Conclusion That serum leptin level is one aecelerate gene in the fibrosis formation in patients with CHB+ALD.

ABSTRACT

<p><b>OBJECTIVE</b>To study the inhibition of voltage-activated K(+) conductance and cell proliferation by 4-aminopyridine (4-AP) in the human small-cell lung cancer (SCLC).</p><p><b>METHODS</b>Inhibition of voltage-activated K(+) current by 4-AP through the whole-cell patch-clamp technique in SCLC cell line was studied. The influence on the cell-cycle by 4-AP was observed by flow cytometry to identify the in vitro inhibition by 4-AP to the cell proliferation of the SCLC cell line.</p><p><b>RESULTS</b>Exposure of the tumor cells to 5 mmol/L 4-AP reduced the peak outward K(+) current (evoked by a depolarization to +80 mV) from 1.22 +/- 0.11 nA (n = 30) to 0.59 +/- 0.10 nA (n = 28). Flow cytometry results showed that cell population accumulated in the G(0)/G(1) phase and a significantly reduced proportion in the S phase and G(1)/G(2) phase cells after having been exposed to 4-AP for three days. Incubation of the SCLC cells with 0.1, 5, 10, 15, 20 mmol/L 4-AP resulted in a concentration-and time-dependent reduction in the number of viable cells as compared with the control.</p><p><b>CONCLUSION</b>The voltage-activated K(+) channels expressed by SCLC play an important role in SCLC cell proliferation. The proliferation of the SCLC cells is inhibited by K(+) channel antagonists.</p>
