ABSTRACT
As a dangerous disease with rapid progression, endotoxemia is easy to induce the damage to multiple organs. However, its specific and efficient treatment methods are still lacking at present. Both Qingkailing Injection(QKLI) and Shengmai Injection(SMI) have been proved effective in anti-inflammation, anti-endotoxin and organ protection. In this study, carrageenan and endotoxin were injected successively into rats to establish an endotoxemia model. Different doses of QKLI and SMI were administered to the endotoxemia rats by intraperitoneal injection separately or in combination. Then the count of white blood cells, the number of platelets, the content of cytokines, biochemical indexes, organ coefficient and pathological changes of main organs in the rats were detected. The results showed that the rats in the model group had obvious symptoms of endotoxemia, i.e., leucopenia, thrombocytopenia, increase in cytokines(IL-6 and TNF-α) and biochemical indexes of liver and kidney function as well as pathological damage to liver, kidney and lung. QKLI alone can alleviate the above symptoms of endotoxemia and the organ injury. SMI alone is less effective in improving disseminated intravascular coagulation(DIC) and cytokine secretion complicated with endotoxemia, but capable of reducing the inflammation degree of the lung, liver and kidney. The combination of QKLI and SMI remarkably increased the number of platelets in the peripheral blood, improved the liver and kidney function and reduced inflammatory factors, with lung, liver, kidney and other organ structures protected well. Moreover, the improvement effect of the combination of QKLI and SMI was stronger than those of the two injections alone at fixed doses, indicative of a synergistic effect.

Aim To study the combination of lysinespecifc demethylase 1 (lysine-specifc demethylase 1, LSD1) inhibitor pargyline and the chemotherapy drug doxorubicin on the proliferation, migration and invasion of murine triple negative breast cancer 4T-1 cells. Methods In vitro, the effect on the proliferation, invasion and migration of 4T-1 cells of the combination of these two drugs were detected with CCK-8 method, lactate dehydrogenase release test, Chou-Talay method, Scratch test, Transwell assay, Western blot and etc. Tumor-bearing mice were used to investigate the combined effect of these two drugs on the proliferation of 4T-1 cells in vivo. Results The combination of pargyline and doxorubicin effectively inhibited the proliferation, migration and invasion of 4T-1 cells. Compared with single drug group, the combination of these two drugs could significantly inhibit the proliferation of breast cancer and prolong the survival time of mice with triple negative breast cancer. Conclusions The combined application of pargyline and doxorubicin has a synergistic inhibitory effect on the proliferation, migration and invasion of mouse breast cancer 4T-1 cells, and has potential value for clinical treatment on triplenegative breast cancer.
ABSTRACT
@#To investigate the effects of sanguinarine (Sang) combined with cisplatin (Cis) in accelerating the apoptosis of bladder cancer EJ cells, CCK-8 method was used to detect the proliferation of bladder cancer EJ cells treated with different concentrations of Sang with the IC50 values calculated. Annexin V FITC/PI method was used to detect cell apoptosis in the control group, Sang group, Cis group and the combination group. Flow cytometer was used to detect cell cycle arrested. Western blot was used to detect the influence of Bcl-2 expression in the control group, Sang group, Cis group and the combination group. Nude mouse subcutaneous tumor model was constructed to verify that the combination group could accelerate the apoptosis of bladder cancer EJ cells and reduce the side-effects on mice. The safety of the Sang was evaluated by HE staining of vital organs in mice. In vitro, Sang could significantly inhibit the proliferation of EJ cells. Compared with the control group, the number of apoptosis EJ cells in the combination group was significantly increased (P < 0.05), and more cells were arrested in G2/M phase. The expression of Bcl-2 was significantly down-regulated in the combination group (P <0.001). In vivo, compared with the control group, the tumor growth was significantly slower, and a large number of apoptotic cells were inspected (P < 0.05) of the combination group. The side effects of cisplatin were reduced in the combination group. Sang has high biosafety and little side effect. Combined Sang and Cis can increase cell cycle G2/M block, down-regulate Bcl-2 expression, promote cell apoptosis and inhibit tumor growth.
ABSTRACT
OBJECTIVE:To observe the clinical efficacy of puerarin combined with β-aescine sodium in the treatment of pa-tients with postoperative edema of hand trauma. METHODS:118 patients with postoperative edema of hand trauma were random-ly divided into observation group (n=59) and control group (n=59) by number. Both groups were taken infrared physiotherapy and appropriate physical treatment such as hand functional exercise;patients in control group was added β-aescine sodium 10 mg based on the physical treatment,iv,once a day;observation group was added puerarin 200 mg based on the treatment of control group,iv,once a day. Both groups were taken 10 days for one course of treatment. Compared the swelling scores,perimeter of suf-fered limb and edema scores,clinical efficacy and adverse reactions of patients between the two groups before and after treatment. RESULTS:The symptoms of hand limb swelling in 2 groups were obviously improved(P<0.01 or P<0.05),however,observa-tion group was better than that of control group,with significant difference(P<0.05);after treatment,the swelling,perimeter of suffered limb and swelling score in observation group were lower than control group,with significant differences(P<0.05);the to-tal effective rate in observation group was 94.91% and control group was 83.05%,with significant difference(P<0.05). No ADR was found in 2 groups. CONCLUSIONS:Puerarin combination with β-aescine sodium has obvious efficacy and safety in the treat-ment of postoperative edema of hand trauma.
ABSTRACT
PURPOSE: To analyze the baseline clinical factors and medication treatment strategy used in cases with medication treatment failure of benign prostatic hyperplasia (BPH). METHODS: From January 2006 to December 2009, 677 BPH patients with at least 3 months of treatment with medication were enrolled. We analyzed clinical factors by medication failure (n=161) versus maintenance (n=516), by prostate size (less than 30 g, n=231; 30 to 50 g, n=244; greater than 50 g, n=202), and by prostate-specific antigen (PSA) levels (less than 1.4 ng/mL, n=324; more than 1.4 ng/mL, n=353). RESULTS: Age, combination medication rate, PSA, and prostate volume were statistically different between the medication treatment failure and maintenance groups. By prostate size, the PSA and medication failure rates were relatively higher and the medication period was shorter in patients with a prostate size of more than 30 g. The combination medication rate was higher in patients with a prostate size of more than 50 g. The medication failure rate and prostate volume were higher in patients with a PSA level of more than 1.4 ng/mL. However, the combination treatment rate was not significantly different in patients with a PSA level lower than 1.4 ng/mL. Suggestive cutoffs for combination medication are a prostate volume of 34 g and PSA level of 1.9 ng/mL. CONCLUSIONS: The clinical factors associated with medication failure were age, treatment type, and prostate volume. Combination therapy should be considered more in Korea in patients with a PSA level higher than 1.4 ng/mL and a prostate volume of between 30 and 50 g to prevent medication failure.
