Cimetidine was given intravenously in daily dose of 20mg/kg to 20 patients with malignant tumor from the operative day on. The results show that cimetidine can elevate CD4, CD4/CD8 and decrease CD8. For comparison, blood samples from 40 patients were taken before operation for extracorporal testing. The results show that cimetidine can elevate lymphocyte transformation test and interleukin-2 secretive cell. These indicate that cimetidine can enhance the immune function of the patient and can be used as an adjunctive treatment of neoplasm.
ObjectiveTo analyze the correlations between the immune function and inflammatory factors levels of patients with hepatocellular carcinoma (HCC) and the results of in vitro high-throughput drug sensitivity, and to provide a reference for personalized drug selection for patients with HCC. MethodsThe patients with HCC who met the inclusion criteria from December 2019 to June 2021 in the First Affiliated Hospital of Chongqing Medical University were included. The HCC cells were used to perform in vitro high-throughput drug sensitivity screening, the result was classified into sensitive and insensitive. The correlations between drug sensitivity results and immune function and inflammatory factors levels of corresponding patients were analyzed, and the relation between these indexes (P<0.05) and drug sensitivity of HCC cells to drugs or combination regimen of drugs was further analyzed by univariate logistic regression. ResultsA total of 74 patients with HCC were included in this study. The results showed that the level of interleukin-6 was negatively correlated with sorafenib, caffezomib, gemcitabine, oxaliplatin + epirubicin + irinotecan + 5-fluorouracil, oxaliplatin + irinotecan + epirubicin, and oxaliplatin + epirubicin regimens on the inhibition rates of HCC in vitro (P<0.05), and positively correlated with bortezomib (P<0.05). However, the level of interleukin-6 was not related to the sensitivity of HCC cells to these single drugs or combined regimens (P>0.05). Meanwhile it was found that tumor necrosis factor (TNF)-α was negatively correlated with cabotinib, apatinib, caffezomib, and epirubicin on the inhibition rates of HCC in vitro (P<0.05), and positively correlated with epirubicin (P<0.05). But only it was found that tumor necrosis factor-α level was related to the sensitivity of HCC cells to epirubicin (P<0.05). ConclusionsTumor necrosis factor-α level in peripheral blood of patients with HCC has a certain relation with epirubicin on inhibition rate of HCC in vitro and it might have a certain value in predicting sensitivity of HCC cells to epirubicin. Meanwhile, although it is found that level of IL-6 is related to sorafenib, caffezomib, gemcitabine, or including combination regiems including oxaliplatin and epirubicin on inhibition rates of HCC in vitro, their value is not found in predicting sensitivity of HCC cells to these single drugs or combined regimens.
In order to investigate pre-and postoperative changes of prostagladin E2 (PGE2) and cellular immune function in patients with gastric cancer (GC), we measured T cell subsets, natural killer cell activity (NKCA) and PGE2 in peripheral blood (PB) of 31 GC patients and 30 controls with APAAP method, LDH release method and radioimmunoassay respectively. The results showed：① a significantly higher levels of PGE2, and a markedly lower levels of CD+4/CD+8 ratio in GC patients before surgery as compared with the controls. The PGE2 had a significant negtive coorelation with CD+4/CD+8 ratio and NKCA respectively.②PGE2 in PB of GC patients gradully declined to normal levels after surgery, moreover PGE2 in tumor tissue was markedly higher than that in normal tissue, implying that the tumor may be the major source of PGE2 in PB. Dynamic determination of PGE2 in PB would be great valuable in evaluation of cellular immune state, to evaluate the effect of surgery and prognosis of patients with gastric cancer.
ObjectiveTo explore the effects of pilose antler blood wine on bone mineral density and T-lymphocyte subsets of ovariectomized female Sprague Dawley (SD) rats. MethodsSixty female SD rats were randomly divided into six groups:normal control group, osteoporosis model group, pure ethylalcohol group, high dose of pilose antler blood wine group, medium dose of pilose antler blood wine group and low dose of pilose antler blood wine group. Normal control group and osteoporosis model group were given saline with the dose of 9.1 g/(kg·d). Pure ethylalcohol group was given pure ethylalcohol with the dose of 9.1 g/(kg·d). The doses of pilose antler blood wine were 4.5, 9.1 and 13.6 g/(kg·d) respectively in low, medium and high dose of pilose antler blood wine group. After the feeding of pilose antler blood wine for 30 days, the bone mineral density and T-lymphocyte subsets of rats were assessed. ResultsThe difference in bone mineral density among the three pilose antler blood wine groups was significant (P<0.05); the most obvious improvement of one mineral density was found in low and medium dose of pilose antler blood wine groups (P<0.05). The CD4+ T cells and CD4+/CD8+ significantly increased and CD8+ T cells proportion decreased significantly in pilose antler blood wine group compared with those in the osteoporosis model group (P<0.05). CD4+ T cells in medium dose group increased obviously compared with that in the high dose group (P<0.05). CD4+/CD8+ in low and medium dose groups obviously increased compared with that in high dose group (P<0.05). CD4+ T cells of medium dose group obviously increased compared with that in pure ethylalcohol group (P<0.05). CD8+ T cells in medium and low dose groups obviously decreased compared that in pure ethylalcohol group (P<0.05). CD4+/CD8+ in the three dose groups increased significantly compared with that in pure ethylalcohol group (P<0.05). ConclusionTree different doses of pilose antler blood wine could prevent the osteoporosis and improve the immune function. The effects of medium and low dose of groups were more obvious.

Objective To detect the expression of cytokeratin 20 (CK20) mRNA (micrometastasis) in regional lymph nodes and the serum activities of CD4+ cells, CD8+ cells and NK cells, serum levels of IL-2, IL-12 and sIL-2R in peripheral blood of patients with colorectal cancer; and to investigate the relationship between them. Methods Total 281 lymph nodes of 21 patients with colorectal cancer were collected. The positive expression of CK20 mRNA in lymph nodes was detect by reverse transcription-polymerase chain reaction (RT-PCR) and the metastasis in lymph nodes was detected by conventional pathological examination; the serum activities of CD4+ cells, CD8+ cells and NK cells were detected by flow cytometry and serum levels of IL-2, IL-12 and sIL-2R were detected by ELISA method in peripheral blood of patients with colorectal cancer. Results Among the positive metastasis in the 281 lymph nodes of the 21 patients, there were 16 (5.7%， 16/281) lymph nodes in 2 patients detected by pathological examination and 140 (49.8%， 140/281) lymph nodes in 10 patients by RT-PCR. There was a significant difference between the two measures in the aspects of the detection rate and the positive cases of lymph node metastasis in the 21 patients. Before operation, the serum activities of CD4+ cells, CD4+/CD8+ and NK cells, levels of IL-2 and IL-12 in 11 patients whose CK20 mRNA in regional lymph nodes were negative expression were higher than those in the other 8 patients whose lymph nodes metastasis were negative by conventional pathological examination but CK20 mRNA were positive expression （P＜0.05）; and the serum activity of CD8+ cells and level of sIL-2R in the former ones were lower than those in the latter ones （P＜0.05）. The serum activities of CD4+（r＝－0.769） cells, CD4+/CD8+（r=－0.755） and NK cells （r=－0.532）, the levels of IL-2 （r＝－0.834） and IL-12 （r＝－0.819） were negative correlated with the expression of CK20 mRNA （P＜0.05, P＜0.01）; and the activity of CD8+ cells （r=0.562） and level of sIL-2R （r=0.751） were positive correlated with the expression of CK20 mRNA （P＜0.05）. Conclusion The micrometastasis in lymph nodes is correlated significantly with the lower immune function of patients with colorectal cancer.
ObjectiveTo explore clinical effect of enteral nutrition (EN) through nasojejunal tube in severe acute pancreatitis (SAP).MethodsThe clinical and pathological data of 76 patients with SAP who met the inclusion criteria and treated in the Third People’s Hospital of Henan Province from June 2015 to December 2018 were retrospectively collected. According to the nutritional support therapy adopted in the course of treatment, the patients were divided into an EN group (n=44) and a parenteral nutrition group (PN group, n=32), the patients in the EN group were given the EN through the nasojejunal tube and the patients in the PN group were given the routine PN. The APACHE Ⅱ and SOFA scores, nutritional status, and immune function were observed before the treatment and on week 2 after the treatment in the two groups.ResultsThere were no significant differences in the general data of the gender, age, body mass index, etc. between the two groups (P>0.050). ① The score of APACHEⅡ or SOFA score on week 2 after the treatment in both groups was significantly lower than that before the treatment (P<0.050), which in the EN group was significantly lower than that in the PN group on week 2 after the treatment (P<0.050). ② The levels of albumin and prealbumin were increased significantly and the hemoglobin level was decreased (P<0.050) on week 2 after the treatment as compared with those before the treatment in the two groups (P<0.050), which in the EN group were significantly higher than those in the PN group on week 2 after the treatment (P<0.050). ③ The CD4, CD8, and CD4/CD8 and IgG, IgM, and IgA on week 2 after the treatment were significantly lower than those before the treatment in these two groups (P<0.050), which in the EN group were significantly higher than those in the PN group on week 2 after the treatment (P<0.050). ④ The levels of endotoxin, D-lactic acid, diamine oxidase, and serum high mobility group protein B1 on week 2 after the treatment were significantly lower than those before the treatment in the two groups (P<0.050), and which in the EN group were significantly lower than those of the PN group on week 2 after the treatment (P<0.050). ⑤ The complications rate in the EN group was significantly lower than that in the PN group [20.45% (9/44) versus 53.13% (17/32), χ2=8.786, P=0.003].ConclusionEN through nasojejunal tube has a good effect on patients with SAP, which is helpful to improve their immune and nutritional status.
Objective To study the effect of perioperative nutritional support on protein metabolism and immunity in patients underwent liver transplantation. Methods A total of 80 patients who underwent liver transplantation in our hospital from March 2015 to March 2016 were collected retrospectively, and then the 80 patients were divided into control group (n=40) and observation group (n=40) according to the type of perioperative nutritional support. Patients of control group didn’t receive preoperatively nutritional support, and received total parenteral nutrition support before postoperative exhaust, then received enteral nutrition support after anal exhaust. Patients of observation group receive preoperatively nutritional support before surgery, and received parenteral nutrition and enteral nutrition support before postoperative exhaust. The several parameters about nutritional status and immune function were observed on 7 days and 14 days after liver transplantation, and comparison of the 2 group in these parameters was performed. Results On the protein metabolism, the levels of serum transferrin, prealbumin, and nitrogen balance on 14 days after liver transplantation were higher than those of other time points (before liver transplantation and 7 days after liver transplantation),P<0.05, both in control group and observation group. There was no significant difference in the levels of serum transferrin, prealbumin, and value of nitrogen balance between the 2 groups before liver transplantation (P>0.05). But on 7 days and 14 days after liver transplantation, the levels of serum transferrin, prealbumin, and value of nitrogen balance of the observation group were higher than those of control group (P<0.05). On the immunity, the total number of lymphocytes, value of IgG and CD4/CD8 on 14 days after liver transplantation, were superior to other time points (before liver transplantation and 7 days after liver transplantation),P<0.05, both in control group and observation group. There was no significant difference in the total number of lymphocytes, value of IgG and CD4/CD8 between the 2 groups before liver transplantation (P>0.05). But on 7 days and 14 days after liver transplantation, the levels of the total number of lymphocytes, value of IgG and CD4/CD8 in the observation group were superior to those of control group (P<0.05). Conclusion Perioperative nutritional support can improve the nutritional status and immune function in patients underwent liver transplantation.
