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.
【Abstract】ObjectiveTo investigate the effect of high intensity focused ultrasound (HIFU) on the immunity of patients with advanced primary liver cancer (PLC). MethodsForty cases of PLC admitted to our institution from Mar. 2003 to Dec. 2003 were included in this study. Patients were divided into 2 groups and received either HIFU or radiofrequency ablation (RFA) treatment randomly. CD3, CD4, CD8, CD4/CD8, NK, IL-2, TNF were chosen to assess the immune status before and after treatment. The results were compared statistically. ResultsThe survival rate after HIFU was 80.0%, 61.1%, 42.9%, 33.3% at 3 months, 6 months, 9 months and 1 year respectively, which was similar to that after RFA treatment. The changes of immunity parameters of CD3, CD4, CD8, CD4/CD8, NK, IL-2 and TNF were not significant after HIFU treatment. In addition, the differences of those parameters between HIFU group and RFA group were insignificant. ConclusionThere are no detrimental effects on immunity in the early period after HIFU treatment.
Objective To explore the pathogens and clinical features of immunocompromised hosts with septicaemia.Methods The data including underlying diseases, peripheral blood granulocyte count, temperature at blood sampling, management and prognosis)of 160 immunocompromised hosts with septicaemia were analyzed retrospectively．Results 8 patients had twice septicaemia in hospital stay and 3 patients had plural pathogenic septicaemia.171 strains of microorganisms were isolated from blood cultured of 160 septic immuno- compromised hosts in which 156 strains (91.2%) were bacteria, 37 strains(21.6%) were gram positive cocci, 6 strains(3.5%) were gram positive bacilli, 113 strains (66.1%) were gram negative bacilli and 15 strains (8.8%) were fungi. Staphylococcus spp (17 strains) and Streptococcus spp (14 strains) were the predominant pathogens among gram positive cocci and Corynebacteria (5 strains ) were the main pathogen in gram positive bacilli while Escherichia coli (60 strains), Klebsiella pneumoniae (20 strains) and Pseudomonas aeruginosa (15 strains) were the most common bacteria in gram negative bacilli. There were 12 strains of Staphylococcus aureus among the 17 strains of Staphylococcus spp, all of them were methicillin sensitive (MSSA). 17 strains of Escherichia coli, 2 strains of Klebsiella pneumoniae and 1 strain of Klebsiella oxytoca produced ESBLs. Candida was the only pathogens of fungemia in this study in which 4 strains of Candida albicans and 11 strains of non-albicans Candida were detected. There were 120 patients(75%) with granulocytopeniain which 103 patients were agranulocytosis. 70% of the 160 paitents had hyperpyrexia. All patients received broad spectrum antibiotics therapy in the study while 58.8% received antifungal drugs at the same time. 20 patients died of septicaemia and 19 patients gave up therapy because of their conditions deteriorated.The overall improvement rate were 75.6%. Conclusions Bacteria are the main pathogens in septicaemia of immunocom- promised host and fungemia is increasing in recent years.Agranulocytosis is a risk factor of septicaemia in immunocompromised hosts. Hyperpyrexia is one of characteristic signs of these patients.
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.
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.
To study the effects of human growth hormone on protein catabolic state of gastric and colonic cancer patients after surgical intervention and whether it can improve the postoperative host immune function and reduce the postoperative fatigue syndrome (POF) by using rhGH. Thirtyeight gastric and colonic cancer patients (21 cases of gastric cancer; 17 cases of colonic cancer) were diveided into control group (n＝18) and rhGHtreated group (n＝20). All the patients were performed resection and treated by early postoperative intraperitoneal thermochemotherapy (EPIC) and total parenteral nutrition (TPN). Subcutaneous injections of 8 U rhGH at 9∶30 am was administered to the rhGHtreated group (six days) at the same time. Results: In the control group, a significant decrease in serum levels of albumin, prealbumin, transferri, IgG, IgA, IgM and CD＋３, CD＋4, CD＋8 were observed after operation (Ｐ＜0.01). In the rhGHtreated group, CD＋３, CD＋4 and CD＋8 raised significantly and the other did not change significantly. The postoperative vigour state of the patient was better than that in the control group. In the control group, pronouced weight loss of 3-5 kg, was detected on the 10th pastoperative day, while the weight loss was 1-2 kg in the rhGHtreated group (Ｐ＜0.01). Conclusion: The treatment with rhGH together with TPN and EPIC not only overcomes the protein catabolism of the cancer patient after operation by increasing protein synthesis, but also improves postoperative host immune function, reduces POF, and can raise the killing effect of chemotherapy on cancer cells, enhances the tolerance to chemotherapy.
