Chinese medicine for outcomes in colorectal cancer patients: A retrospective clinical study / 中国结合医学杂志

<p><b>OBJECTIVE</b>To investigate the effect of Chinese medicine (CM) on survival of patients with stage II and III colorectal cancer (CRC).</p><p><b>METHODS</b>A total of 295 patients who received chemotherapy were assigned to Group 1. The other 171 patients received the same chemotherapy treatment combined with the usage of CM Jianpi Jiedu Formula (, JPJD) for more than 3 months (Group 2). Patients' survival time, relapse and metastasis, and cause of death were observed. Cox proportional hazard regression models were established for the analysis of the effect of independent factors on the survival prognosis of patients with CRC.</p><p><b>RESULTS</b>The survival rate of patients in Group 2 was higher than that of Group 1 (P<0.05). Compared with Group 1, the mean survival time was prolonged by 5.594 months and the median survival time was prolonged by 6 months in Group 2 (P=0.004). Cox regression analysis indicated that CM combined with chemotherapy provided signifificant protective effect, as observed with the improvements in the survival rates of CRC patients (P<0.01).</p><p><b>CONCLUSION</b>CM can improve the survival rate in patients with stage II and III CRC.</p>

Effects of Fengbaisan on the expression of matrix metalloproteinase-9 and tissue inhibitor of metalloproteinase-1 in lung tissue of rats with chronic obstructive pulmonary disease / 中国结合医学杂志

<p><b>OBJECTIVE</b>To observe effects of Fengbaisan (, FBS) on the expression of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in lung tissue of rats with chronic obstructive pulmonary disease (COPD) and to investigate the preventive and therapeutic mechanisms of FBS.</p><p><b>METHODS</b>The COPD rat model was established by cigarette smoke exposure and lipopolysaccharide (LPS) intra-tracheal dripping. The histopathological changes of lung tissue was observed via hematoxylin/eosin staining. The expression of MMP-9 and TIMP-1 in lung tissue was measured by reverse transcription polymerase chain reaction (RT-PCR) and immunohistochemistry.</p><p><b>RESULTS</b>The typical histopathological changes of COPD were displayed in the model group, Ambroxol Hydrochloride group and FBS group, and the pathological lesions in the FBS group were less than those in the model group. The expression of MMP-9 and TIMP-1 in the model group increased significantly compared with those in the normal group (P<0.05). After treatment for successive 28 days, the expression of MMP-9 and TIMP-1 in the FBS group decreased remarkably as compared with the model group (P<0.05).</p><p><b>CONCLUSIONS</b>FBS can regulate MMP-9/TIMP-1 imbalance to prevent airway and lung parenchyma remodeling process via reducing the expression of MMP-9 and TIMP-1 in the lung tissue of COPD rats, and this may be a possible therapeutic mechanism of FBS on COPD.</p>

Effects of Fuzhengyangying granules on the bone marrow proliferation and bcl-2 expression in mice with immune mediated aplastic anemia / 中南大学学报(医学版)

OBJECTIVE@#To explore the effect of Fuzhengyangying granules (FZYYG) on the expression of the bone marrow proliferation and bcl-2 in mice with immune mediated aplastic anemia.@*METHODS@#Forty BALB/c mice were randomly allocated to 4 groups: a normal control group, a model group, cyclosporine A (CSA) group and FZYYG group. The model group was fed with physical salt, while the CSA and FZYYG group were fed with CSA and FZYYG respectively, and then the changes of peripheral hemoglobin (Hb), platelet, bone marrow nucleus cell (BMNC), bone marrow hematopoiesis tissue volume and bcl-2 expression were examined.@*RESULTS@#The count of Hb, the platelet, BMNC, the bone marrow hematopoiesis tissue volume and the bcl-2 positive rate in the model group were lower than those in the normal group (P<0.05), whereas the count of Hb, the platelet, BMNC, the bone marrow hematopoiesis tissue volume and the bcl-2 positive rate in both CAS and FZYYG groups were significantly higher than those in the model group (P<0.05).@*CONCLUSION@#FZYYG can induce the bcl-2 antigen expression and postpone the haematogenous cells apoptosis, and it is effective for mice with immune mediated aplastic anemia.

Effect of naoling decoction on the behavior and the mRNA expression of beta-amyloid precursor protein in the hippocampus in rats with Alzheimer's disease / 中南大学学报(医学版)

OBJECTIVE@#To observe the effect of naoling decoction (NLD) on the behavior and the mRNA expression of beta-amyloid precursor protein (APP) in the hippocampus in rat model with Alzheimer's disease (AD).@*METHODS@#D-galactose was intra-abdominally injected and AlCl3was hypodermically injected to build the AD models. The behavior of rats was measured by gamma-electric maze and the level of APP mRNA in the model rat hippocampus was observed by RT-PCR.@*RESULTS@#The learning and memory capacity in the NLD group was improved and the APP mRNA expression level was significantly lower in the NLD group compared with the untreated model and the control group (All P < 0.05).@*CONCLUSION@#NLD can lower the expression of APP mRNA to reduce beta-amyloid protein deposition of rat hippocampus, which may be one of the mechanisms of improving the learning and memory capacity of AD model rats.

Therapeutic effect of fuzheng yangying oral solution on immune-induced aplastic anemia mice / 中南大学学报(医学版)

OBJECTIVE@#To observe the effect of fuzheng yangying oral solution on bone marrow proliferation and serum interleukin 2 in immune-induced aplastic anemia mice.@*METHODS@#The immune-induced aplastic anemia mouse models were built up, and then were divided into 4 groups by randomized allocation. The models were fed with physical salts (Group A, n = 10 ), fuzheng yangying oral solution (Group B, n = 10), cyclosporin A (Group C, n = 10), and fuzheng yangying oral solution plus cyclosporin A (Group D, n =10), respectively. Another 10 healthy mice served as controls (Group E). The changes in blood cells, bone marrow karyocyte count, marrow hematopoietic tissue capacity, and serum interleukin 2 level were observed.@*RESULTS@#The blood cells, bone marrow karyocyte count, and marrow hematopoietic tissue capacity in Group A were significantly lower than those of Group E (P 0. 05 ). The level of interleukin 2 in Group A was obviously higher than that of Group E (P < 0. 05 ); The levels of interleukin 2 in the 3 treated group ( Group B, C, and D) were significantly lower than those of Group A ( P < 0. 05 ); and Group D was the lowest ( P < 0. 05). There was no significant difference in the level of interleukin 2 between Group B and C ( P < 0. 05).@*CONCLUSION@#Fuzeng yangying oral solution can impove the bone marrow proliferation and reduce the level of serum interleukin 2 in immune-induced aplastic anemia mice.
