ABSTRACT
Objective:To investigate the clinical efficacy of modified Guipi Decoction combined with omeprazole in the treatment of acute non-variceal upper gastrointestinal bleeding (ANVUGIB) with failure of the spleen to control blood vessels syndrome.Methods:Prospective cohort study. A total of 120 patients from January 2018 to December 2021 Taihe County Hospital of Traditional Chinese Medicine with ANVUGIB of failure of the spleen to control blood vessels syndrome were selected, and the patients were divided into observation group and control group according to the random number table method, with 60 cases in each group. The control group was treated with a large dosage of proton pump inhibitor (omeprazole injection was injected intravenously first, and then omeprazole enteric coated tablets were taken); the observation group took Guipi Decoction on the basis of the control group, and both groups were treated for 7 days. TCM syndrome score, Hemoglobin (Hb) and hematocrit (HCT) levels were measured by colorimetry before and after the treatment. BUN was detected by urease glutamate dehydrogenase method. Prothrombin time (PT), activated partial thromboplastin time (APTT) and fibrinogen (FIB) levels were detected by immunoturbidimetry. The adverse reactions during treatment were recorded and the clinical efficacy was evaluated.Results:Two patients in the observation group and two patients in the control group dropped out of the study. After treatment, the scores of main symptoms, secondary symptoms and total scores in the observation group were lower than those in the control group ( t values were respectively 10.73, 4.45, 7.98, P<0.05). After treatment, the levels of HCT [(41.25 ± 5.03)% vs. (38.19 ± 5.26)%, t=2.95], Hb [(81.09 ± 5.23) g/L vs. (78.39 ± 5.37) g/L, t=2.74] in the observation group were higher than those in the control group ( P<0.01), and BUN [(4.38±0.96) mmol/L vs. (5.39 ± 1.13) mmol/L, t=5.19] was lower than that in the control group ( P<0.01); PT [(12.48 ± 0.67) s vs. (13.22 ± 0.73) s, t=5.69], APTT [(24.66 ± 2.29) s vs. (27.78 ± 2.04) s, t=7.75] were lower than those in the control group ( P<0.01), and FIB [(3.68 ± 0.62) g/L vs. (3.41 ± 0.74) g/L, t=2.13] level was higher than that in the control group ( P<0.05). The total effective rate of the observation group was 93.1% (54/58), and that of the control group was 79.3% (46/58), with statistical significance ( χ2=4.64, P=0.031). During the treatment, the incidence of adverse reactions in the control group was 3.4% (2/58), while that in the observation group was 1.7% (1/58), without statistical significance ( χ2=0.34, P=0.559). Conclusion:High-dosage omeprazole treatment with the addition of internal administration of Guipi Decoction can significantly improve coagulation function, correct the signs and symptoms associated with insufficient blood volume in the body circulation, improve hemostatic efficiency, and reduce the risk of bleeding in patients with ANVUGIB, without increasing the risk of patient safety with the drug.
ABSTRACT
Background/Aims@#This study aimed to explore the effect of gut microbiota-regulated Kupffer cells (KCs) on colorectal cancer (CRC) liver metastasis. @*Methods@#A series of in vivo and in vitro researches were showed to demonstrate the gut microbiota and its possible mechanism in CRC liver metastasis. @*Results@#Fewer liver metastases were identified in the ampicillin-streptomycin-colistin and colistin groups. Increased proportions of Parabacteroides goldsteinii, Bacteroides vulgatus, Bacteroides thetaiotaomicron, and Bacteroides uniforms were observed in the colistin group. The significant expansion of KCs was identified in the ampicillin-streptomycin-colistin and colistin groups. B.vulgatus levels were positively correlated with KC levels. More liver metastases were observed in the vancomycin group. An increased abundance of Parabacteroides distasonis and Proteus mirabilis and an obvious reduction of KCs were noted in the vancomycin group. P. mirabilis levels were negatively related to KC levels. The number of liver metastatic nodules was increased in the P. mirabilis group and decreased in the B. vulgatus group. The number of KCs decreased in the P. mirabilis group and increased in the B. vulgatus group. In vitro, as P. mirabilis or B. vulgatus doses increased, there was an opposite effect on KC proliferation in dose- and time-dependent manners. P. mirabilis induced CT26 cell migration by controlling KC proliferation, whereas B. vulgatus prevented this migration. @*Conclusions@#An increased abundance of P. mirabilis and decreased amount of B. vulgatus play key roles in CRC liver metastasis, which might be related to KC reductions in the liver.
ABSTRACT
BACKGROUND:High expression of stem cell transcription factors, Sox2 and Oct4, has been confirmed to be closely related to the occurrence of lung cancer.OBJECTIVE:To explore the expression of Sox2 and Oct4 in lung cancer tissues and its correlation with microvascular generation and clinical-pathologic features.METHODS:The expression levels of Sox2 and Oct4 and microvessel density (MVD) in lung cancer tissues (60 cases) and normal tissues (60 cases) were examined by immunohislochemistry. Then, the correlation of the expression of Sox2 and Oct4 and MVD value with clinical-pathologic features in lung cancer was analyzed.RESULTS AND CONCLUSION:The positive expression of Sox2 and Oct4 was 46.67% (28/60) and 71.67% (43/60) in lung cancer tissues, respectively, while Sox2 and Oct4 were negatively expressed in normal tissues, and there was a significant difference between lung cancer and normal tissues (P 0.05). The MVD value with Sox2 and Oct4 positive expression was significantly higher than that with Sox2 and Oct4 negative expression (P 0.05). To conclude, the high expression of Sox2 and Oct4 has a high correlation with the initiation and progression of lung cancer, and has positive correlation with the MVD, both of which are significantly concerned with the microvascular generation, invasion and hematogenous metastasis of lung cancer.
ABSTRACT
Objective To investigate the relationship between prothrombin fragment 1+2 (F1+2) and peripherally inserted central catheter (PICC) associated thrombosis in cervical cancer patients, and provide certain clinical basis of early prevention in peripherally inserted central catheter associated thrombosis in cervical cancer patients. Methods One hundred and forty cervical patients with PICC were enrolled in this study, and they were divided into thrombosis group (35 patients) and non-thrombosis group (105 patients). The level of F1+2 was examined using enzyme-linked immunoassay, and was analyzed according to the clinic features. Results The level of F1+2 was correlated with clinical stage (r = 0.640, P = 0.004);but was not correlated with age, type of tumor and concurrent radiochemotherapy (P>0.05). The level of F1+2 in thrombosis group was (520.343 ± 121.759) pmol/L, in non- thrombosis group was (388.361 ± 104.873) pmol/L, and there was significant difference (P =0.001). The multi-factors Logistic analysis showed that the level of F1+2 (OR=1.011, P=0.001) and age (OR = 21.025, P = 0.031) were independent risk factors for the PICC associated with thrombosis in cervical cancer. Conclusions The level of F1+2 is closely related with clinical stage and PICC associated thrombosis, and it is an independent risk factor for the PICC associated with thrombosis in cervical cancer.

ABSTRACT
Objective To investigate the inhibition mechanism of tetramethylpyrazine combined with cisplatin on angiogenesis in Lewis lung cancer mice and to observe the mechanism of Arresten on angiogenesis in lung cancer. Methods The model of Lewis lung adenocarcinoma mouse xenograft was established in this work, and 40 mice were randomly divided into 4 groups: 0.9% sodium chloride solution group(NS group), tetramethylpyrazine group(TMP group), cisplatin group(DDP group), tetramethylpyrazine plus cisplatin group(TMP + DDP group), 10 mice in each group.Mice in NS group were given 0.2 mL of 0.9% sodium chloride solution, mice in DDP group were given 0.2 mL of 2 mg.kg-1 of cisplatin, mice in TMP group were given 0.2 mL of 100 mg.kg-1 of tetramethylpyrazine, mice in TMP+DDP group were given 2 mg.kg-1 of cisplatin and 100 mg.kg-1 of tetramethylpyrazine, each 0.1 mL .Tumor size was measured every day to calculate the tumor volume.The mice were sacrificed to stripp the subcutaneous tumor after continuous medication. The expressions of Arresten, integrin α1β1 and VEGF were determinated by immunhistochemistry and Western blotting. Results The tumor growth of NS group was the fastest and TMP+DDP group was the slowest. Compared with NS group, the expression of Arresten in the other three groups was increased( P<0.01) , and the TMP+DDP group exhibited the highest expression;at the same time, integrin α1β1 , VEGF in the other three groups was decreased(P<0.01), and the TMP+DDP group exhibited the lowest expression.The expression of integrinα1β1 and VEGF was negatively related to Arresten, and the expression of integrin α1β1 was positively correlated with VEGF. Conclusion TMP can inhibited the growth of Lewis lung carcinoma and angiogenesis. Moreover, in combination with cisplatin, TMP can also improved the effect of chemotherapy and then the survival state of mice. The mechanism of action, which TMP suppress tumor angiogenesis may be through improving Arresten and inhibiting integrin α1β1 and VEGF. And the action mechanism of Arresten may be implemented by inhibiting the expression of VEGF by incorporation with integrinα1β1 or by itself to inhibit the expression of VEGF.

ABSTRACT
Objective To study the effect of astrocyte-derived factors on the differentiation of neural stem cells from neonatal rats. Methods Neural stem cells from neonatal rats were isolated, cultured and expanded by neurosphere formation. Astrocytes were isolated and purified by a standard shaking method and the differential adhesion technique. With immunocytochemical labeling, the purity of astrocytes was determined by the expression of glial fibrillary acidic protein(GFAP). Astrocytes and neural stem cells were co-cultured without contact. Immunofluorescence examination was used to detect the effects of astrocyte-derived factors on the expression of neuron specific enolase (NSE), GFAP, and tyrosine hydroxylase(TH) of the differentiated cells. Results The purified astrocytes were 98% of GFAP positive. Co-culturing the neurospheres with astrocytes promoted more neural stem cells rapidly differentiationinto NSE positive cells( P
ABSTRACT
Objective To study the sequence of learning and memory loss in the rat after hemispheric irradiation. Methods After Sprague Dawly(SD) female rats were anaesthetized with chloral hydrate, their cerebral hemispheres were irradiated with a single dose of 5,15 or 30?Gy by 4?MeV electron. On D3,D7,D30 and D60, the learning and memorizing ability was measured with the Y maze test. Results On D3 and D7, the learning ability of SD rats was impaired most but partly restored in 1 to 2 months. In observation of memory loss, the intensity of cerebral function damage was in direct proportion to the increase of radiation dose.Conclusion The learning and memorizing ability of rats can be damage by hemispheric irradiation with the severity of impairment and possibility of recruitment depending on the dose.
ABSTRACT
The studies on the antihypoxia mechanism of 18?-SGA were reported. The survival time of hypoxia mice were longer than those of the control after intraperitoneal injections of 14mg/kg or 21mg/kg of 18?-SGA ( Sodium 18?-glycyrrenetic acid). Changes of various physiological indications after administration of the drug were as follows: blood pH was risen; acidosis was relieved; and the partial pressure of oxygen in the mixed blood was decreaed. The blood thyroxine level remain unchanged. It suggests the utilization of oxygen by the tissues was strengthened.
