RESUMO
Objective:To investigate the efficacy of tirellizumab combined with chemotherapy in the treatment of advanced non-small cell lung cancer and its effect on immune function and quality of life in patients.Methods:In this retrospective case-control study, we analyzed the clinical data of 104 patients with advanced (stages III and IV) non-small cell lung cancer who received treatment at Zhoushan Hospital between May 2021 and June 2022. These patients were divided into two groups: group A ( n = 52) and group B ( n = 52), based on the treatment methods utilized. Patients in group A received chemotherapy with gemcitabine plus cisplatin or pemetrexed plus cisplatin. Meanwhile, patients in group B were treated with tirellizumab combined with chemotherapy regimens of gemcitabine plus cisplatin or pemetrexed plus cisplatin, with 21 days as a treatment cycle. Both groups of patients received three cycles of treatment. The short-term efficacy was compared between the two groups. Additionally, serum levels of tumor markers, immune function indexes, quality of life score, and incidence of adverse reactions were compared between the two groups before and after treatment. Results:The short-term response rate in group B was significantly higher than that in group A [51.92% (27/52) vs. 32.69% (17/52), Z = 4.11, P < 0.001]. When compared with pretreatment levels, serum levels of tumor markers and the percentage of CD8 + cells decreased in both groups after treatment. Notably, the serum levels of tumor markers and the percentage of CD8 + cells were significantly lower in group B compared with group A (all P < 0.05). Moreover, after treatment, the percentage of CD4 + cells, the ratio of CD4 +/CD8 + cells, functional subscale, symptom subscale, and total score increased significantly compared with pretreatment levels (all P < 0.05) and were significantly higher in group B compared with those in group A (all P < 0.05). The incidence of adverse events in group B was significantly higher than that in group A [44.23% (23/52) vs. 21.15% (11/52), χ2 = 6.29, P = 0.012]. Conclusion:Tirelizumab combined with chemotherapy is effective for advanced non-small-cell lung cancer. The combined therapy can lower serum levels of tumor markers, restore immune function, and improve overall quality of life.
RESUMO
Objective:To investigate the efficacy of thymalfasin combined with ganciclovir eye drops (gel) in the treatment of herpes simplex virus epithelial keratitis.Methods:This study enrolled 80 patients with herpes simplex virus epithelial keratitis who were treated at the Department of Ophthalmology, Fenyang Hospital, between January 2019 and December 2020. These patients were randomly divided into a control group and an observation group, with 40 patients in each group using the random number table method. All patients were treated with ganciclovir eye drops (gel) for 3 weeks. The control group received conventional treatment, while the observation group received both conventional treatment and thymalfasin treatment. All patients were followed up for 2 years. The proportion of patients who achieved a significant response and an effective response within 10 days of treatment, as well as the recurrence rate, were compared between the two groups. Additionally, the changes in cellular immune function were compared between the two groups.Results:In the control group, there were 10 cases that achieved a significant or effective response within 10 days of treatment, while in the observation group, there were 28 cases. The therapeutic effect of the observation group was superior to that of the control group, and the difference was statistically significant ( χ2 = 16.24, P < 0.001). The recurrence rate of the observation group within 2 years was significantly lower than that of the control group (10.00% vs. 30.00%, χ2 = 5.00, P < 0.05). After treatment, the counts of CD3 +, CD4 +, CD4 +/CD8 +, and natural killer cells, which are indices of cellular immune function, were significantly increased in the observation group compared with both their pre-treatment levels and the levels measured concurrently in the control group ( tbetween-group= 19.27, 20.85, 11.32, 15.82, all P < 0.001). Conclusion:The combination of thymalfasin and ganciclovir eye drops (gel) for the treatment of herpes simplex virus epithelial keratitis can improve both the therapeutic effect and the immune function of patients, which helps to reduce the recurrence rate.
RESUMO
Objective:To explore the differences in tumor-specific growth factors, cellular immune function and efficacy of olaparib and platinum-containing regimen for treatment of platinum-sensitive relapsed ovarian cancer patients with BRCA mutation.Methods:A retrospective cohort study was conducted. A total of 100 platinum-sensitive relapsed BRCA-mutant ovarian cancer patients in Baoding Second Central Hospital from September 2017 to March 2020 were retrospectively selected. The clinical data of the patients were analyzed, and they were divided into the olaparib group (treated with olaparib tablets) and the platinum-containing regimen group (treated with paclitaxel and platinum drugs for 6 cycles, followed by olaparib tablets maintenance therapy), with 50 patients in each group. The clinical efficacy, tumor specific growth factor [carbohydrate antigen (CA) 125, CA199, human epididymal protein 4 (HE4)] levels, cellular immune function-related indicators [T-cell subsets (proportions of CD3 + cells and CD4 + cells), CD4 + cells/CD8 + cells ratio (CD4 +/CD8 +)], and quality of life scores before treatment and after 2, 4 and 6 cycles of treatment of the two groups were compared, as well as the safety of the two groups. The data of three years of follow-up were obtained, Kaplan-Meier method was used to analyze the progression-free survival (PFS) of patients in the two groups, and log-rank test was used for comparison between groups. Results:The age of patients in the olaparib and platinum-containing regimen groups was (53±7) years old and (56±7) years old, respectively. The differences in compositions of patients with different age, body mass index, Eastern Cooperative Oncology Group (ECOG) performance status score, primary tumor location, lesion size, pathological stage, pathological type, germline BRCA mutation, and previous chemotherapy response between the two groups were not statistically significant (all P > 0.05). The objective response rate (ORR) [58.0% (29/50) vs. 38.0% (19/50)] and disease control rate (DCR) [80.0% (40/50) vs. 56.0% (28/50)] of the olaparib group after treatment were higher than those of the platinum-containing regimen group, and the differences were statistically significant (both P < 0.05). Serum CA125, CA199 and HE4 levels were gradually decreased in both groups before treatment and after 2, 4 and 6 cycles of treatment (all P < 0.05); serum CA125, CA199 and HE4 levels in the olaparib group after 2, 4 and 6 cycles of treatment were lower than those in the platinum-containing regimen group, and the differences were statistically significant (all P < 0.05). The CD3 + cells ratio, CD4 + cell ratio and CD4 +/CD8 + in the olaparib group gradually increased before treatment and after 2, 4 and 6 cycles of treatment (all P < 0.05), while those in the platinum-containing regimen group all gradually decreased (all P < 0.05); the CD3 + cells ratio, CD4 + cells ratio and CD4 +/CD8 + in the olaparib group were higher than those in the platinum-containing regimen group after 2, 4 and 6 cycles of treatment, and the differences were statistically significant (all P < 0.05). The quality of life scores of both groups increased before treatment and after 2, 4 and 6 cycles of treatment (all P < 0.05), and the quality of life scores of the olaparib group were higher than those of the platinum-containing regimen group after 2, 4 and 6 cycles of treatment, and the differences were statistically significant (all P < 0.05). The incidence of nausea, fatigue and malaise, vomiting, anemia, and diarrhea at all levels in the olaparib group was lower than those in the platinum-containing regimen group (all P < 0.05). By follow-up for 3 years, there was no statistically significant difference in PFS between the olaparib group and the platinum-containing regimen group ( P > 0.05). Conclusions:The efficacy of olaparib treatment in platinum-sensitive relapsed ovarian cancer patients with BRCA mutation is superior to platinum-containing regimen, and it can increase the level of T cells, inhibit the expression of tumor-specific growth factors, improve the quality of life, and have a positive effect on improving the safety of treatment.
RESUMO
Hepatocellular carcinoma (HCC) is a common malignant tumor of the liver characterized by a high incidence rate, rapid progression, and poor prognosis. In recent years, it has been found that non-coding RNA (ncRNA) participates in the regulation of tumor immunity in tumor microenvironment (TME) and in turn affects the biological behavior of HCC. This article briefly describes the regulatory effect of ncRNA on immune cells in TME and introduces the potential value of ncRNA in the diagnosis and treatment of HCC, in order to provide potential diagnostic and treatment strategies for HCC.
RESUMO
Objective:To evaluate the effect of electroacupuncture preconditioning on cellular immune function in the patients undergoing thyroid surgery.Methods:Sixty-six patients of either sex, aged 30-55 yr, with body mass index of 18.5-23.9 kg/m 2, of American Society of Anesthesiologists Physical Status classification ⅠorⅡ, were selected and divided into electroacupuncture preconditioning group (group D) and control group (group C) by a random number table method, with 33 cases in each group. Patients in both groups received combined intravenous-inhalational anesthesia. Before anesthesia induction, both Hegu and Neiguan acupoints were stimulated for 30 min using a continuous wave at a frequency of 2/100 Hz, and the stimulation intensity was subjected to patient tolerance in group D. Group C received sham electroacupuncture for 30 min without stimulation. Venous blood samples were collected at 30 min before anesthesia induction (T 0) and 12, 24 and 48 h after anesthesia (T 1-3). The percentages of T lymphocyte subsets (CD3 +, CD4 +, CD8 +, CD4 + /CD8 + ) and natural killer cells and concentrations of interleukin-6 and tumor necrosis factor-alpha in the serum were measured by flow cytometry. Results:Compared with group C, the percentage of CD3 +, CD4 + and natural killer cells and ratio of CD4 + /CD8 + were significantly increased at T 1, 2, and the concentrations of interleukin-6 and tumor necrosis factor-alpha in the serum were decreased at T 1-3 in group D ( P<0.05). Conclusions:Electroacupuncture preconditioning can improve cellular immune function in the patients undergoing thyroid surgery.

RESUMO
Objective:To evaluate the correlation between anti-C1q antibody and disease activity and cellular immune function in patients with systemic lupus erythematosus (SLE).Methods:The clinical data and test indexes of 134 patients with SLE and 90 healthy people who were admitted to Henan Provincial People′s Hospital from June 2017 to February 2018 were collected. The level of anti-C1q antibody was measured by enzyme-linked immunosorbent assay (ELISA), and lymphocyte subsets were measured by flow cytometry. According to the score of Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)-2K, SLE patients were divided into active and inactive groups, and SLE patients were divided into LN group and non-LN group according to the presence or absence of kidney involvement. The levels of anti-C1q antibodies and lymphocyte subsets were compared among the three groups, and correlations between anti-C1q antibodies and disease activity and lymphocytes were analyzed. The predictive value of anti-C1q antibodies and anti double stranded DNA (dsDNA) antibodies for SLE disease activity was evaluated.Results:The anti-C1q antibody level, percentage of T cells and Ts cells in SLE group were higher than those in control group, while the percentage of Th cells, percentage of NK cells, T cell count, Th cell count, B cell count and NK cell count in SLE group were lower than those in control group (all P<0.05); The anti-C1q antibody level in the active group was higher than that in the inactive group, and the counts of T cells, Ts cells, Th cells, B cells and NK cells were lower than those in the inactive group (all P<0.05); The anti-C1q antibody level in LN group was higher than that in non-LN group, and the T cell count, Ts cell count, Th cell count, B cell count, NK cell count were lower than that in non-LN group, with statistically significant difference (all P<0.05). Correlation analysis showed that age, hemoglobin (HB), C3, C4, T cell count, Th cell count, B cell count and NK cell count were negatively correlated with anti-C1q antibody, while SLEDAI-2K, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and anti-dsDNA antibody were positively correlated with anti-C1q antibody (all P<0.05). Receiver operating characteristic (ROC) curve analysis showed that the area under the curve (AUC) of anti-C1q antibody alone in predicting SLE disease activity was 0.702, with a sensitivity of 0.547 and a specificity of 0.827. The combination of anti-C1q and anti ds-DNA antibodies resulted in an AUC of 0.761, a sensitivity of 0.756, and a specificity of 0.691. The combined detection value of the two antibodies predicting SLE disease activity was better than the single detection. Conclusions:Anti-C1q antibody is closely related to disease activity and cellular immune dysfunction, and has certain predictive value in SLE disease activity.
RESUMO
Dura mater, rich in vasculature and immune cells, is the outermost layer of the central nervous system, and thus acts as the first barrier to protect brain. Meningeal lymphatic vessels and immune cells are main components of dural immunity, which respond to a variety of central nervous system diseases. Meanwhile, compared with brain parenchyma, dura mater communicates more with peripheral tissues and is more susceptible to medical interventions. Therefore, dura mater is a promising target to prevent, diagnose and treat intracranial diseases. Here dural immunity is clarified based on meningeal lymphatic vessels and dural immune cells, and current researches inquiring the role of dural immunity in infectious and immune diseases of central nervous system are summarized.
RESUMO
Objective:To evaluate the effect of perioperative transcutaneous electrical acupoint stimulation (TEAS) on postoperative cellular immune function in the patients undergoing posterior spinal internal fixation.Methods:Ninety patients, aged 40-70 yr, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, undergoing elective posterior spinal internal fixation in our hospital, were divided into 2 groups ( n=45 each) using a computer-generated table of random numbers: routine group and experiment group.Total intravenous anesthesia was used in routine group, while total intravenous anesthesia combined with TEAS was applied in experiment group.In experiment group, bilateral Zusanli and Sanyinjiao acupoints were stimulated with 2/15 Hz disperse-dense waves at the intensity that could be tolerated by patients at 30 min before induction of anesthesia, maintaining with 2/100 Hz disperse-dense waves from the end of induction until the end of operation at the same stimulation intensity before induction.Bilateral Neiguan and Taichong acupoints were stimulated for 30 min each time with 2/15Hz disperse-dense waves once a day at 1st-4th days after operation.In routine group, the electrodes were connected at the same time period, but no stimulation was given.Venous blood samples were collected before induction of anesthesia, at 1 h after surgery, and on 1st, 3rd, and 5th days after surgery, and the percentage of CD3 + , CD4 + , CD8 + T lymphocytes, CD4 + /CD8 + ratio, WBC count and percentage of neutrophils (NE%) were determined by flow cytometry, and the consumption of intraoperative anesthetics, use of postoperative analgesics, nausea and vomiting, dizziness, infection and length of hospital stay were recorded. Results:Compared with routine group, the total consumption and consumption index of remifentanil were significantly decreased, the percentage of CD3 + T lymphocytes was increased on 3rd and 5th postoperative days, the NE% was decreased on 1st postoperative day, and the incidence of dizziness was decreased ( P<0.05), and no significant change was found in the other indicators in experiment group ( P>0.05).

RESUMO
Objective:To investigate the effect of radiofrequency ablation treatment of extrahepatic cholangiocarcinoma under endoscopic retrograde cholangiopancreatography on the cellular immune function of patients with extrahepatic cholangiocarcinoma.Methods:A prospective cohort study was conducted on 78 patients with inoperable extrahepatic cholangiocarcinoma who visited Shanxi Provincial People's Hospital from October 2019 to January 2022. All of 78 patients underwent endoscopic radiofrequency ablation. Peripheral venous blood was collected from all patients at 1 day before treatment, 1 week after treatment and 1 month after treatment. Lymphocyte subsets were detected by flow cytometry, and levels of cytokines were detected by enzyme-linked immunosorbent assay. Seventy-eight healthy subjects with the same age and gender as the patients were selected as healthy controls, and the same indicators were tested.Results:The patient's peripheral blood total bilirubin was (193±83) μmol/L at 1 day before treatment, and decreased to (55±49) μmol/L at 1 week after treatment ( t = 16.70, P < 0.001); γ-glutamyltransferase was (242±108) U/L at 1 day before treatment, and decreased to (92±70) U/L at 1 week after treatment ( t = 19.12, P < 0.001). The proportion of natural killer (NK) cells, CD3 + T cells, CD4 + T cells, ratio of CD4 + T cells to CD8 + T cells (CD4/CD8) and level of interferon γ (IFN-γ) of patients at 1 day before treatment were lower than those of healthy control group (all P < 0.05), the proportion of CD8 + T cells and regulatory T cells was higher than those of healthy control group (both P < 0.001), and there was no significant difference in the levels of interleukin 4 (IL-4) between the patients at 1 day before treatment and the healthy control group ( P = 0.545). At 1 week and 1 month after treatment, the proportion of NK cells, CD3 + T cells, CD4 + T cells, CD4/CD8 and IFN-γ level in patients increased compared with 1 day before treatment (all P < 0.001), and decreased at 1 month after treatment compared with 1 week after treatment (all P < 0.001). At 1 week and 1 month after treatment, the proportion of CD8 + T cells and IL-4 level in patients decreased compared with 1 day before treatment (both P < 0.001), and increased at 1 month after treatment compared with 1 week after treatment (both P < 0.001). At 1 week and 1 month after treatment, the proportion of regulatory T cells decreased compared with 1 day before treatment (both P < 0.001), and decreased at 1 month after treatment compared with 1 week after treatment ( P < 0.001). Conclusions:Patients with extrahepatic cholangiocarcinoma are at a low level of immunity. Endoscopic radiofrequency ablation treatment can alleviate the patient's immunosuppression, enhance the patient's cellular immunity.

RESUMO
Chronic insomnia is a common sleep disorder in clinic. It is a frequent and persistent difficulty in sleep initiation, maintenance and termination, leading to different degrees of functional impairment during daytime awakening. Although its pathogenesis is still not completely clear, some people have proposed neurobiological and psychological models, and more and more people begin to pay attention to the study of immune factors and genetic factors. The immune system mainly includes immune organs, immune cells and immune molecules, which help organisms maintain their homeostasis and normal life activities. There are intricate relations between sleep and immune system. Chronic insomnia can affect the function of immune system, and immune disorder may in turn lead to chronic insomnia. This paper discusses the changes of immune system in patients with chronic insomnia, and the influence of immune system changes on patients with chronic insomnia, as well as the research progress of the correlation between chronic insomnia and immune function.
RESUMO
microRNA (miRNA) is a class of non-coding single-stranded RNA molecules of approximately 20-22 nucleotides in length, encoded by endogenous genes, which is involved in post-transcriptional regulation of gene expression in plants and animals. miRNA exists in a double-stranded form and is single-stranded when activated. miRNA also plays its role by forming miRNA-induced silencing complex, and is involved in various processes such as cell growth, differentiation, senescence, apoptosis, autophagy, migration and invasion. Hypopharyngeal carcinoma is a kind of rare malignant neoplasm with unknown etiology and poor prognosis. The early symptoms cannot be detected easily, which is prone to missed diagnosis and misdiagnosis. The main pathological type of hypopharyngeal carcinoma is squamous cell carcinoma accounting for 95% that can easily develop cervical lymph node metastasis. The role of miRNA in hypopharyngeal squamous cell carcinoma is of great importance to the targeted therapy of hypopharyngeal squamous cell carcinoma. This paper reviews the progress of the role of miRNA in hypopharyngeal squamous cell carcinoma.

Methods:Thirty cases of pregnant women with PROM (PROM group), 30 cases of normal pregnant women (normal pregnancy group) and 30 cases of normal non-pregnant women (non-pregnancy group) who treated in Binhai County People′s Hospital from September 2019 to May 2020 were collected. Peripheral blood of each group was collected and the proportion of CD 8+ CD 25+ FoxP3 + Treg was determined by flow cytometry. Peripheral blood mononuclear cells (PBMCs) were extracted and FoxP3 mRNA was determined by polymerase chain reaction (PCR). The levels of Th1-related cytokines interferon-γ (IFN-γ), interleukin (IL)-2, and Th2-related cytokines IL-10 and IL-4 were measured by Luminex liquid phase microarray. The effects of CD 8+ CD 25+ FoxP3 + Tregexpression on Th1/Th2 balance were analyzed. Results:The proportion of CD 8+ CD 25+ FoxP3 + Tregand the expression of FoxP3 mRNA in PROM groupand normal pregnancy group were lower than those in non-pregnancy group: (0.15 ± 0.03) %, (0.35 ± 0.09) % vs. (0.47 ± 0.11) %; 0.89 ± 0.11, 3.15 ± 0.67 vs. 3.75 ± 0.23 , the proportion of CD 8+ CD 25+ FoxP3 + Treg and the expression of FoxP3 mRNA in PROM groupwere lower than those in the normal pregnancy group , and the differences were statistically significant ( P<0.05). The levels of Th1-related cytokines IFN-γ and IL-2 in PROM group and normal pregnancy group were higher than those in non-pregnancy group, the level of Th2-related cytokines IL-4 was lower than that in non-pregnancy group , the levels of IFN-γ and IL-2 in PROM group were higher than those in normal pregnancy group, the level of IL-4 was lower than that in normal pregnancy group , and the differences were statistically significant ( P<0.05). In PROM group, the proportion of CD 8+ CD 25+ FoxP3 + Treg and the expression of FoxP3 mRNA in peripheral blood were negatively correlated with Th1-related cytokines IFN-γ ( r = - 0.413, -0.451, P<0.05) and IL-22 ( r = -0.645, -0.535, P<0.05), and were positively correlated with Th2-related cytokines IL-4 ( r = 0.558, 0.469, P<0.05). Conclusions:The proportion of CD 8+ CD 25+ FoxP3 + Treg in peripheral blood of pregnant women with PROM is lower, and the expression level of related FoxP3 mRNA is lower, which all affecte the Th1/Th2 immune balance and cause Th1 immune drift, which may be the related immune mechanism of PROM.
RESUMO
Objective:To investigate the effects of modified Sijunzi Decoction on myelosuppression in moderate- and advanced-stage lung cancer patients with Qi and Yin deficiency and analyze the underlying mechanism. Methods:A total of 100 moderate- and advanced-stage lung cancer patients with Qi and Yin deficiency who received treatment in Lishui Hospital of Traditional Chinese Medicine, China were included in this study. They were randomly assigned to receive chemotherapy with paclitaxel combined with cisplatin (control group, n = 50) or treatment with modified Sijunzi Decoction based on chemotherapy with paclitaxel combined with cisplatin (observation group, n = 50). Myelosuppression, traditional Chinese medicine symptom score, cellular immune function, serum levels of granulocyte-macrophage colony-stimulating factor and granulocyte colony-stimulating factor, and the dosage of recombinant human granulocyte-colony stimulating factor. Results:After treatment, the incidence of leucopenia, thrombocytopenia, hemoglobinopenia and neutropenia in the observation group were 60% (30/50), 18% (9/50), 18% (9/50) and 62% (31/50), respectively, which were significantly lower than those in the control group [90% (45/50), 30% (15/50), 32% (16/50) and 92% (46/50), χ2 = 6.979, 7.025, 6.534, 6.134, all P < 0.001]. The complete remission rate in the observation group was significantly higher than that in the control group [30% (15/50) vs. 8% (4/50), χ2 = 9.018, P < 0.001]. The traditional Chinese medicine symptom score in the observation group was significantly lower than that in the control group ( t = 6.982, P < 0.05). CD 8+, CD 4+ and CD 3+ levels in the observation group were (25.16 ± 2.87)%, (38.76 ± 4.16)%, (48.83 ± 5.61)%, respectively, and they were (28. 89 ± 4.02)%, (34.10 ± 4.59)%, (41.12 ± 77)%, respectively in the control group. There were significant differences in CD 8+, CD 4+ and CD 3+ levels between the observation and control groups ( t = 6.392, 6.235, 5.983, all P < 0.05). The dosage of recombinant human granulocyte-colony stimulating factor in the observation group was significantly lower than that in the control group [(2 567.34 ± 308.25) μg vs. (3 917.82 ± 411.67) μg, t = 11.258, P < 0.05]. Serum levels of granulocyte-macrophage colony-stimulating factor and granulocyte colony-stimulating factor were (25.53 ± 7.86) ng/L and (278.34 ± 28.74) ng/L, which were significantly higher than those in the control group [(21.30 ± 3.12) ng/L, (204.17 ± 11.98) ng/L, t = 9.136, 8.856, both P < 0.05]. Conclusion:Modified Sijunzi Decoction for the treatment of moderate- and advanced-stage lung cancer patients with Qi and Yin deficiency can decrease the incidence of myelosuppression possibly through increasing serum levels of granulocyte-macrophage colony-stimulating factor and granulocyte colony-stimulating factor and improving the immune function.
RESUMO
Idiopathic pulmonary fibrosis (IPF) is a common pulmonary interstitial disease with unknown etiology. Its pathogenesis is unknown and there is no specific drug. Its progress is urgent and its prognosis is heterogeneous. Many studies have found that abnormal immune system function of the body and lungs may be related to the pathogenesis, progression and prognosis of IPF. Combined with the literature, this paper comprehensively analyzes the distribution of IPF related immune cells, cytokines and immunoglobulins in peripheral blood and bronchoalveolar lavage fluid of IPF patients, and discusses the research potential and clinical application potential value of these cells and molecular markers as immune evaluation and monitoring for IPF diagnosis, condition evaluation and prognosis prediction.
RESUMO
Fracture healing is a complex biological process. After a fracture, a hematoma will first form at the injured site, and immune cells and inflammatory factors will quickly reach the fracture site to facilitate the repair and reconstruction of bone tissue. Immune cells and inflammatory factors are an important part of the body's immune system, and the immune system plays a key role in removing necrotic tissue and maintaining the homeostasis of the body's environment. Proper immune regulation after a fracture is beneficial to fracture healing; if immune regulation is improper, the fracture site will gradually develop into a chronic inflammatory state, which may impair healing. The authors summarize the mechanism of action of the innate immune system and adaptive immune system in fracture healing, as well as the research progress of therapeutic drugs that affect the state of the immune system and thus affect the healing of fractures, so as to deepen the understanding of the immune system affecting bone regeneration and provide new ideas for clinical treatment of fracture.
RESUMO
Objective:To investigate immune effects of aminolevulinic acid-based photodynamic therapy (ALA-PDT) on mouse models of cutaneous squamous cell carcinoma (cSCC) .Methods:Ultraviolet-induced SKH-1 hairless mouse models of cSCC were established, and 40 tumor-bearing mice were randomly and equally divided into several groups: control group receiving no treatment, and 7 treatment groups treated with ALA-PDT for 1, 3, 6, 12 and 24 hours, as well as 3 and 7 days respectively. After treatment, these mice were sacrificed at different time points, and skin tissues measuring 5 mm 3 in size were resected. Immunohistochemical study and flow cytometry were performed to detect local infiltration of immune cells in cSCC tissues at different time points, including neutrophils, macrophages, T cells, B cells, natural killer cells and dendritic cells. Statistical analysis was done by the two-sample t test using SPSS 16.0 software. Results:The number and proportion of local neutrophils and macrophages showed the most significant increase in mouse cSCC tumors 1 hour after ALA-PDT compared with those before treatment (immunohistochemical results [number of cells per 400 × field]: 61.22 ± 6.65 vs. 22.56 ± 4.13, 59.67 ± 4.30 vs. 21.89 ± 3.26, respectively, both P < 0.05; flow cytometry results: 35.64% ± 15.33% vs. 5.46% ± 2.44%, 12.15% ± 4.86% vs. 1.98% ± 1.49%, respectively, both P < 0.05) . Both immunohistochemical study and flow cytometry showed that the expression of T cells, B cells, natural killer cells and dendritic cells significantly increased in cSCC tissues 6 hours after treatment (all P < 0.05) . After reaching the peak, the number and proportion of the above-mentioned cells decreased in cSCC tissues, but were still higher than those before treatment, and the increase continued until the end of this study, that is, day 7 after treatment. Conclusion:ALA-PDT may exert anti-tumor effects by recruiting immune cells, especially neutrophils and macrophages.
