ObjectiveTo investigate effect of application of thymopentin during perioperative period on immune function of patients undergoing laparoscopic assisted radical resection for rectal carcinoma. MethodsForty-two patients undergoing laparoscopic assisted radical resection for rectal carcinoma from January 2015 to April 2015 in this hospital were collected. These patients were divided into study group and control group. The patients were received routine treatment in the control group. In addition to routine treatment same as the control group, the patients were received 2 mg thymopentin every day for a week in the study group. The changes of lymphocyte count, T lymphocyte subsets (CD3+, CD4+, CD8+, and CD4+/CD8+), and immunoglobulin (IgG, IgA, and IgM) were compared on the 1st day before surgery and on the 1st day and 5th day after surgery. ResultsThe lymphocyte count, T lymphocyte subsets, and immunoglobulin on the first day after surgery were significantly lower than those on the 1st day before surgery in these two groups (P < 0.05). The lymphocyte count, T lymphocyte subsets (except for CD4+/CD8+), and immunoglobulin (except for IgA) in the study group were significantly higher than those in the control group on the 5th day after surgery (P < 0.05). The changes of lymphocyte count, T lymphocyte subsets, and immunoglobulin in the study group had no significant differences between on the 5th day after surgery and on the 1st day before surgery (P > 0.05), but which on the 5th day afer surgery were significantly lower than those on the 1st day before surgery (P < 0.05) in the control group. ConclusionApplication of thymopentin during perioperative period could accelerate recovery of immune function after operation in patients undergoing laparoscopic assisted radical resection for rectal carcinoma.
Objective To observe the effect of parenteral nutrition (PN) on the protein storage and immunofunction in patients with liver cirrhosis. Methods PN regimes consisted of nonprotein calories (NPC) 20-25 kcal/(kg·d) and nitrogen 0.15-0.20 g/(kg·d), the energy ratio of the glucose and fat emulsion was 2∶1. The PN solution was infused by total nutrition admixture (TNA), 12-16 hours per day for 7 days in 21 liver cirrhosis patients. Perior to the surgery and at 1st, 4th, 7th postoperative day, serum pre-Alb, transferrin (TSF), immunofunction (IgG, IgA, IgM, IgE, CH50, C3, C4, CD3, CD4, CD8, NKC), and nitrogen balance were tested. Results Serum pre-Alb, TSF, nitrogen balance and IgG, IgE, CH50, CD3, CD4, NKC were significantly decreased (Ｐ＜0.05), but the foregoing indices were higher than those of postoperative 1, 4d as compared with postoperative 7d. Conclusion These results bly indicated that postoperative nutritional support is safe and useful, and improve the patient’s nutritional status and immunofunction.
Objective To summarize the role of the relationship between liver cancer and cellular immunological function, and the role of immune therapy in clinical application. Methods To analyze the relationship between liver cancer and cellular immunological function, and the present research situation of immune therapy for liver cancer in clinical application retrospectively via review the related domestic and foreign literatures. Results The cellular immune dysfunction existed in all liver cancer patients. The state of body’s cellular immunological function is closely related with the arising and development of liver cancer, and the lowness of cellular immunological function is an important factor of hepatocellular carcinoma hard to cure or recurrence and metastasis. Immune therapy plays an important role in the treatment of liver cancer by adjusting the body’s cellular immunological function. Conclusions Liver cancer is closely related with the body’s cellular immunological function. Immune therapy is expected to offer a new way for the treatment of liver cancer, which can also be used as an important auxiliary treatment way.
ObjectiveTo investigate the effects of early enteral nutrition containing ω-3 polyunsaturated fatty acids combined with intravenous infusion of alanyl-glutamine on inflammatory response and immune function of postoperative gastric cancer patients.MethodsA total of 110 patients, accepting radical operation for gastric cancer in West China Hospital of Sichuan University during October 2017 to December 2018, were prospectively incorporated in the study and were randomly divided into 2 groups equally. Patients in the control group were enterally fed with a formula containing ω-3 polyunsaturated fatty acids for 6 consecutive days after surgery. Patients in the experimental group accepted the same enteral feeding but combined with intravenous infusion of alanyl-glutamine (20 g/d). Both enteral feeding and intravenous infusion started within 24 hours after surgery. Peripheral venous blood was gathered within 3 days before surgery and on the morning of the first, third, and seventh postoperative days to detect inflammatory, immunological, and nutritional indexes. Complications, length of hospital stay, and hospital cost were also taken notes.ResultsFifty-two patients in the control group and fifty-two patients in the experimental group respectively finished the study. In both groups, 3 patients withdrew from the study for inadequacy of radical operation. Neutrophilic granulocyte percentage, interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) on the third postoperative day, C-reactive protein (CRP), procalcitonin (PCT), IL-6, and TNF-α on the seventh postoperative day, were significantly lower in the experimental group (P<0.05). Immunological indexes including immunoglobulin G (IGG), immunoglobulin A (IGA), percentage of CD3+ T cells, and percentage of CD4+ T cells, nutritional markers including total protein (TP), plasma albumin (ALB), and prealbumin (PAB) were significantly higher in the experimental group on the seventh postoperative day (P<0.05). When the study ended, none significant differences of the rates of both infectious complications (wound infection, intra-abdominal infection, pulmonary infection, urinary system infection, blood system infection, and anastomotic fistula) and noninfectious complications (diarrhea, abdominal distension, and abdominal pain) were observed between the two groups (P>0.05). Time of the first anal discharge, length of hospital stay, and hospitalization cost between the two groups were not significantly different neither (P>0.05).ConclusionEarly enteral nutrition containing ω-3 polyunsaturated fatty acids combined with intravenous infusion of alanyl-glutamine contributes to reduce inflammatory response and improve immune function and nutrition status of patients with gastric cancer after surgery.
ObjectiveTo evaluate the effects of sentinel lymph node biopsy following total mastectomy on immunologic function and prognosis for patients with early breast cancer. MethodsTwo hundred and eleven patients with early breast cancer were entered in this study. In all these cases, the results of sentinel lymph node biopsy were negative. These patients were randomly divided into control group and research group. In 86 cases of control group, the sentinel lymph node biopsy and axillary lymph node dissection following total mastectomy was performed. In 125 cases of research group, the sentinel lymph node biopsy following total mastectomy was performed. The injury of shoulder joint function was analyzed in one year after surgery. The changes of T cell subsets and IL-2 level were detected in the patients respectively on the first day before operation, the second week after operation, and the fourth week after operation. Postoperative fatality rate and postoperative recurrence rate were also observed in two groups. Results①The points of shoulder joint function in the control group and the research group were 72.7±6.5 and 93.5±8.2 respectively, there was an obvious difference (P < 0.05).②The injury degree of shoulder joint function in the research group was significantly lower than that in the control group (P < 0.01).③Compared with the control group, the changes of T cell subsets and the IL-2 level had no significant differences in the research group on day 1 before operation and on week 2 after operation (P > 0.05). On the fourth week after surgery, the CD4+, CD4+/CD8+, and IL-2 level in the research group were obviously higher than those in the control group (P < 0.05). However, the percentage of CD8+ T cell in the research group was significantly lower than that in the control group (P < 0.05).④There were no significant differences for postoperative fatality rate and postoperative recurrence rate between two groups (P > 0.05). ConclusionsSentinel lymph node biopsy for patients with early breast cancer is safe and reliable. With respect to conventional axillary lymph node dissection, it could improve immune function and quality of life after surgery in patients with early breast cancer.
ObjectiveTo investigate the effects of Huaier granule combined with systemic chemotherapy on immunologic function and prognosis for advanced breast cancer patients. MethodsNinety-eight cases ofⅣstage breast cancer from March 2006 to March 2009 in this hospital were divided into control group and research group. Only systemic chemotherapy was performed in the control group, while Huaier granule combined with systemic chemotherapy was applied in the research group, and Huaier granule was given on day 1 systemic chemotherapy start. The changes of T lymphocyte subsets and IL-2 level were detected on day 1 before systemic chemotherapy and on month 6 after Huaier granule combined with systemic chemotherapy. The fatality rate and median survival time were also observed between two groups. ResultsCompared with the control group, the changes of T lymphocyte subsets and IL-2 level had no signi-ficant differences on day 1 before systemic chemotherapy between these two groups(P > 0.05). On month 6 after Huaier granule combined with systemic chemotherapy, the CD4+, CD4+/CD8+ T lymphocyte, and IL-2 level were significantly increased, the CD8+ T lymphocyte was significantly decreased in the research group as compared with the control group〔CD4+:(47.35±6.23)% versus(41.33±5.61)%, P < 0.05; CD4+/CD8+: 1.84±0.42 versus 1.47±0.33, P < 0.05; IL-2 level:(1.78±0.45)μg/L versus(1.58±0.30)μg/L, P < 0.05; CD8+:(23.26±3.25)% versus(29.77±4.12)%, P < 0.05〕. The rate of chemotherapy complications and fatality rate within 3 years were significantly decreased in the research group as compared with the control group〔rate of chemotherapy complications: 58.3%(28/48) versus 86.0%(43/50), P < 0.01; fatality rate within 3 years: 62.5%(30/48)versus 82.0%(41/50), P < 0.05〕. The median survival time in the research group was significantly longer than that in the control group(33.5 months versus 24.5 months, P < 0.01). ConclusionsThe preliminary results from this study show that Huaier granule combined with systemic chemotherapy could greatly enhance immune function, reduce side-toxicity of chemotherapy and improve prognosis in advanced breast cancer patients. It provides a beneficial exploration for cancer treatment by integration of traditional and western medicine.

To study the effects of arginine supplementation in total parenteral nutrition (TPN) on lymphocytic immune function in postoperative patients with gastric cancer. Thirty six patients with gastric cancer receiving TPN were eligible for entry into randomized and prospective clinical trial of the study. T cell subsets, NK cell activity, plasma IL-2 content and peripheral blood CD25 were measured in before and after parenteral nutrition of the patients. Results: usual TPN could not improve lymphocytic immunosuppression of postoperative patients with gastric cancer. The patients receiving arginine supplementation in TPN might enhance lymphocytic immune function by increasing CD4 level, IL-2 production and NK cell activity, but there was no significant effect of arginine on CD25 expression. Conclusion: there are some effects of supplement with arginine on releasing of the cellular immunosuppression and restoring of lymphocytic immune function.
