ABSTRACT
ObjectiveTo explore the effects and possible mechanism of Wenshen Tongdu Formula （温肾通督方， WTF） on spinal cord injury. MethodsThirty-six C57BL/6 female mice were randomly divided into sham operation group， model group and WTF group， with 12 mice in each group. The spinal cord injury model was established in the model group and the WTF group using the modified Allen's method， while in the sham operation group the spinal cord was only exposed. Since the 1st day after surgery， 50 g/（kg·d） of WTF solution was given to the WTF group by gavage， while 20 ml/（kg·d） of normal saline was given to the sham operation and model group by gavage， all for 14 days. Before surgery and on the 1st， 7th， and 14th days after surgery， the motor function of the mice was evaluated using the inclined plane test and hind limb motor function score （by BMS）. On the 3rd day after surgery， the nerve electrophy-siology was detected through electromyography and motor evoked potential； the spleen length was measured， and B cells in the spleen were sorted by magnetic beads； the differential expression of proteins were detected through proteomics technology； and the protein expression of mitochondrial outer membrane transport porin 20 （Tom20） and downstream cleaved caspase-3 in spleen B cells were measured using Western blotting. On the 14th day after surgery， MRI was used to observe the recovery of the spinal cord. ResultsCompared to those in the sham operation group at the same time， the BMS scores and subscores and the inclined plane test angle in the model group were reduced on the 1st， 7th and 14th days after surgery； the peak value of electromyogram and motor evoked potential were reduced， and the spleen length was shortened， while the expression of Tom20 and cleaved caspase-3 increased in splenic B cells increased （P＜0.05）. Compared to those in the model group at the same time， the BMS subscores on the 14th day and the angle of the inclined plane test on the 7th and 14th days after surgery increased in the WTF group； the peak value of electromyography and motor evoked potential， as well as the length of spleen increased， and the expression of Tom20 and cleaved caspase-3 decreased （P＜0.05）. The proteomics results showed that there were 100 differential proteins in the WTF group versus the model group， of which 37 were up-regulated and 63 were down-regulated. GO enrichment analysis showed that differential proteins mainly played their roles in oxygen binding， exogenous apoptosis negative feedback， zinc ion response， and oxygen transport. KEGG enrichment analysis showed that differential proteins were mainly concentrated in metabolic pathways， Huntington's disease， oxidative phosphorylation and other pathways. Subcellular localization showed that differential proteins were associated with mitochondria. Magnetic resonance imaging on the 14th day after surgery showed that the spinal cord structure of the mice in the sham operation group was intact， and the segments were clear， with normal spinal cord signal； the low signal area in the spinal cord injury area increased in the model group， and the spinal cord became significantly thinner； the injured segment had obvious depression in the WTF group， but the structure was more complete than that in the model group. ConclusionWTF may promote spinal cord injury repair by regulating immune function， and its mechanism may be related to inhibiting pyroptosis of spleen B cells.
ABSTRACT
ObjectiveTo explore the effects of modified Gualou Zhishitang combined with piperacillin sodium and tazobactam sodium on the immune function and serum levels of inflammatory cytokines in the patients with stroke-associated pneumonia （SAP， syndrome of phlegm-heat accumulation in lung）. MethodEighty SAP patients with the syndrome of phlegm-heat accumulation in lung were randomized into a control group （40 cases） and a study group （40 cases）. The SAP patients in the control group were treated with piperacillin sodium and tazobtam sodium， while those in the study group were treated with modified Gualou Zhishitang on the basis of the treatment in the control group for 2 consecutive weeks. The clinical therapeutic effects， immune function indexes， inflammation indexes， and lung function of SAP patients in the two groups before and after treatment were determined and compared. ResultAfter treatment， the scores of lesion， pulmonary rales， cough， fever， phlegm color， and constipation in both groups decreased （P<0.05）. After treatment， the ratio of forced expiratory volume in the first second to forced expiratory volume （FEV1/FVC） and forced expiratory volume in the first second as percentage of predicted value（FEV1%） in both groups improved （P<0.05）， and the study group outperformed the control group （P<0.05）. The treatment decreased the neutrophil to lymphocyte ratio （NLR） in the two groups （P<0.05）， and the study group had lower NLR than the control group after treatment （P<0.05）. The serum levels of procalcitonin （PCT） and hypersensitive C-reactive protein （hs-CRP） in both groups declined after treatment （P<0.05）， and the declines were more significant in the study group than in the control group （P<0.05）. After treatment， the study group was better than the control group （P<0.05）. The treatment in both groups elevated the levels of CD3+， CD4+， and CD4+/CD8+ in the peripheral blood and lowered the level of CD8+ （P<0.05）， and the changes were more significant in the study group than in the control group （P<0.05）. The total response rate of the study group was 95.00% （38/40）， which was higher than that （80.00%， 32/40） of the control group （χ2=4.114，P<0.05）. There was no significant difference in the incidence of adverse reactions between the two groups. ConclusionModified Gualhou Zhishitang combined with piperacillin sodium and tazobactam sodium demonstrates a significant therapeutic effect on the SAP patients with the syndrome of phlegm-heat accumulation in lung. This therapy can mitigate the clinical symptoms， improve the lung function， lower the serum levels of inflammatory cytokines， and improve the immune capacity， with high safety.

Results:The expression levels of CD3 + T cells, CD4 + T cells, CD4 +/CD8 + and NK cells were 71±8, 39±7, 1.5±0.5, 16±7, respectively in HSIL group, and 73±9, 41±9, 1.5±0.6, 16±9, respectively in early cervical cancer group, which were lower than those in the healthy control group (76±9, 45±10, 2.0±1.3, 20±7) (all P < 0.05). The expression levels of CD8 + T cells was 28±7, 29±8, respectively in HSIL group and early cervical cancer group, which were higher than those in the healthy control group (24±7) (all P < 0.05). The expression level of total B cells in early cervical cancer group was lower than that in healthy control group (10±4 vs.12±3, P < 0.05). The expression level of CD3 + T cells in peripheral blood of early cervical cancer patients with tumor diameter >4 cm and nerve/vascular invasion was 71±10 and 72±8, which was lower than that of patients with tumor diameter 2-4 cm, ≤2 cm and without nerve/vascular invasion (72±8, 75±8, 78±7); the expression level of CD8 + T cell was 32±8 and 35±4, which was higher than that of patients with tumor diameter 2-4 cm, ≤2 cm, and without nerve/vascular invasion (28±8, 28±7, 29±8) (all P < 0.05). The levels of CD3 + T cells and total B cells were negatively correlated with the tumor diameter (all P < 0.05), while the level of CD8 + T cells was positively correlated with tumor diameter ( P < 0.05); the levels of CD3 + T cells and NK cells were negatively correlated with nerve/vascular invasion (all P < 0.05). Conclusions:The immune function of the body starts to change in the early progression of cervical cancer, and is related to the tumor diameter and nerve/vascular invasion of cervical cancer.
ABSTRACT
Objective:To explore the effects of different doses of dexmedetomidine (DEX) on inflammatory factors and immune function in patients with gynecological malignant tumors who underwent laparoscopic surgery.Methods:A total of 60 patients with gynecological malignant tumors who underwent laparoscopic surgery from January 2021 to December 2021 in the Second Hospital of Shanxi Medical University were selected as the research objects. All patients were divided into the control group, low-dose DEX group (group D1) and high-dose DEX group (group D2) by using random number table method, 20 cases in each group. Patients in D1 and D2 groups were intravenously pumped DEX 0.5 μg/kg and 1.0 μg/kg 10 minutes before induction of anesthesia, and then maintained with DEX 0.5 μg·kg -1·h -1 and 1.0 μg·kg -1·h -1 until 30 minutes before the end of operation; and patients in the control group were given the same amount of Nacl solution. The 10 ml peripheral venous blood were collected at 10 minutes before induction of anesthesia (T 1), 1 h after pneumoperitoneum relief (T 2) and 24 h after pneumoperitoneum relief (T 3). The changes of interleukin-6 (IL-6), interleukin-10 (IL-10), the proportion of CD4 +, the proportion of CD8 + and CD4 +/CD8 + ratio of the three groups were compared, and the cases of bradycardia and hypotension in perioperative period and the time of first exhaust after operation were recorded. Results:At T 1,T 2 and T 3, the expression level of IL-6 in the control group was (7.95±0.26) pg/ml, (8.30±0.24) pg/ml and (8.35±0.28) pg/ml, respectively, and the difference was statistically significant ( F = 14.14, P < 0.001); the expression level of IL-10 in the control group was (38.9±2.6) pg/ml, (44.5±6.6) pg/ml and (46.3±4.6) pg/ml, respectively, and the difference was statistically significant ( F = 12.45, P < 0.001); the proportion of CD4 + in the control group was (38.5±2.1)%, (29.5±4.6)% and (29.6±3.5)%, respectively, and the difference was statistically significant ( F = 40.82, P < 0.001); the ratio of CD8 + in the control group was (30.1±3.7)%, (35.1±6.3)% and (40.3±8.2)%, respectively, and the difference was statistically significant ( F = 13.02, P < 0.001); the CD4 +/CD8 + ratio in the control group was 1.29±0.14, 0.84±0.09 and 0.75±0.14, respectively, and the difference was statistically significant ( F = 99.94, P < 0.001). The expression level of IL-6 in group D1 and group D2 was (8.10±0.32) pg/ml and (8.01±0.30) pg/ml at T 2, and (8.12±0.35) pg/ml and (8.05±0.34) pg/ml at T 3,which were lower than those in the control group, and the differences were statistically significant (all P < 0.05). The expression level of IL-10 in group D2 was (40.6±3.5) pg/ml at T 2, which was lower than that in the control group, and the difference was statistically significant ( P < 0.05). At T 3, the expression level of IL-10 in group D1 and group D2 was (43.7±3.5) pg/ml and (42.4±3.9) pg/ml, which were lower than those in the control group, and the differences were statistically significant (all P < 0.05). At T 2, the proportion of CD4 + in group D2 was (34.5±4.3)%, which was higher than that in the control group, and the difference was statistically significant ( P < 0.05). At T 3, the proportion of CD4 + in group D1 and group D2 was (32.1±4.2)% and (33.7±2.8)%, which were higher than those in the control group, and the differences were statistically significant (all P < 0.05). At T 2, the proportion of CD8 + in group D2 was (30.7±5.5)%, which was lower than that in the control group, and the difference was statistically significant ( P < 0.05). At T 3, the proportion of CD8 + in group D1 and group D2 was (35.4±5.8)% and (32.5±5.1)%, which were lower than those in the control group, and the differences were statistically significant (all P < 0.05). The CD4 +/CD8 + ratio in group D1 and D2 was 0.99±0.17 and 1.14±0.16 at T 2, 0.93±0.19 and 1.05±0.16 at T 3, which were higher than those in the control group, and the differences were statistically significant (all P < 0.05). Meanwhile, 1 case of hypotension occurred in the the control group and group D1, respectively; 3 cases of bradycardia and 2 cases of hypotension occurred in the group D2. The time of exhaust in the control group was later than that in group D1 and D2, and the difference was statistically significant ( P < 0.05). Conclusions:DEX can inhibit the inflammatory reaction during laparoscopic surgery in patients with gynecological malignant tumors, reduce immune damage. The anti-inflammatory action and immune protection of high-dose of DEX is more significant compared with low-dose of DEX, while high dose of DEX is more likely to cause hemodynamic fluctuations in perioperative period.
ABSTRACT
Objective:To investigate the effect of tripartite motif-containing 23 (Trim23) on the differentiation and maturation of dendritic cells and the possible mechanism.Methods:Mouse bone marrow-derived dendritic cells (BMDCs) were prepared from bone marrow cells of C57BL/6 mice with the presence of Flt3L. Real-time quantitative PCR and Western blot were used to detect the expression of Trim23 in BMDCs after LPS stimulation. An overexpression vector for full-length Trim23 (Trim23 OE) was constructed and transfected into BMDCs, and the pcDNA3.1 empty vector was used as control. Flow cytometry was used to detect the expression of CD80, CD86, CD40 and MHCⅡ on the surface of vector-transfected BMDCs after LPS stimulation and ELISA was used to detect the secretion of IL-12p40, TNF-α, IL-6 and IL-10 by these cells. CD8 + and CD4 + T cells were isolated from spleen and lymph nodes of OT-Ⅰ and OT-Ⅱ mice by magnetic beads and co-cultured with LPS-treated BMDCs in the presence of ovalbumin (OVA). Flow cytometry was used to detect the proliferation and differentiation of CD8 + and CD4 + T cells. Western blot was performed to analyze the phosphorylation of p38, ERK1/2 and AKT in BMDCs. Two overexpression vectors for Trim23 mutants lacking RING or ARF domain (Trim23 ΔRING and Trim23 ΔARF) were constructed and transfected into BMDCs. Then flow cytometry and ELISA were used to detect the expression of surface molecules and cytokines. Results:The expression of Trim23 in BMDCs was significantly down-regulated after LPS stimulation. The expression of MHCⅡ, CD86 and CD80 and the secretion of TNF-α and IL-6 decreased significantly in BMDCs overexpressing Trim23. Furthermore, overexpression of Trim23 inhibited the ability of BMDCs to induce the proliferation and differentiation of CD4 + T cells and the proliferation of CD8 + T cells. Western blot showed that the phosphorylation of p38 and ERK1/2 decreased significantly in Trim23-overexpressing BMDCs. Compared with wildtype Trim23, overexpression of Trim23 ΔRING had no significant influence on the expression of surface molecules (MHCⅡ and CD86) and the secretion of cytokines (TNF-α and IL-6) in BMDCs stimulated by LPS. Conclusions:Trim23 overexpression inhibited the maturation and immune activation of BMDCs via MAPK signal pathway and its RING domain. This study provided reference for targeting Trim23 to improve the immune response of dendritic cell-based tumor vaccines.
ABSTRACT
Cryptococcus gattii is a kind of Cryptococcus that infects the lungs and central nervous system through the inhalation of infectious particles such as spores or Cryptococcus yeast cells. The development of clinical disease of Cryptococcus gattii may be determined by the sex, immunity and genetics of the host factors, in which immune system factors play an important role in host injury. Their defects will have serious clinical consequences. Cryptococcus gattii mainly infects the population with normal immune, and the infection of immunosuppressed population is rare. The infection mechanism, molecular types, clinical characteristics, treatment and prognosis of Cryptococcus gattii meningitis were different between the two populations. This article reviews the main differences in different immune status with Cryptococcus gattii meningitis.
ABSTRACT
ObjectiveTo evaluate the clinical efficacy of Qimai Qinlou prescription in the treatment of elderly community-acquired pneumonia （CAP） （non-severe） with Qi and Yin deficiency and phlegm-heat obstructing lung syndrome and its impact on immune-inflammatory factors. MethodA total of 120 eligible patients were randomly divided into an observation group （60 cases） and a control group （60 cases）. Both groups received intravenous cefoxitin sodium. In addition， the observation group received oral Qimai Qinlou prescription， while the control group received an oral placebo simulating Qimai Qinlou prescription. The treatment course was 14 days. The disappearance time of major clinical symptoms and signs was recorded. Traditional Chinese medicine （TCM） syndrome scores and the Clinical Research Outcome （CAP-CRO） scale scores for pneumonia of the two groups were compared. Chest computed tomography （CT） scans were performed， and peripheral blood levels of procalcitonin （PCT）， interleukin-6 （IL-6）， serum amyloid A （SAA）， high-sensitivity C-reactive protein （hs-CRP）， CD4+， CD8+， and CD4+/CD8+ were measured. The conversion rate to severe condition during hospitalization， readmission rate within 30 days after discharge， and safety evaluation were recorded. ResultAfter treatment， the observation group showed significantly shorter time of fever， cough， expectoration， and disappearance time of lung moist rales than the control group （P<0.01）. The TCM syndrome scores， CAP-CRO scores in all dimensions， and total scores in both groups were significantly reduced as compared with those before treatment （P<0.01）. After treatment， the observation group had a more significant reduction than the control group （P<0.01）. The levels of PCT， IL-6， SAA， and hs-CRP in both groups were significantly reduced as compared with those before treatment （P<0.01）. After treatment， the observation group showed a more significant reduction than the control group （P<0.01）. There was no statistically significant difference in the changes of CD4+， CD8+， and CD4+/CD8+ in the control group before and after treatment. However， in the observation group， CD4+ and CD4+/CD8+ levels significantly increased （P<0.01）， while CD8+ level significantly decreased （P<0.01） after treatment. After treatment， CD4+ and CD4+/CD8+ in the observation group significantly increased （P<0.01）， and CD8+ significantly decreased as compared with those in the control group （P<0.01）. At 7， 10， and 14 days after treatment， the curative rates in the observation group were 53.33% （32/60）， 85.00% （51/60）， and 91.67% （55/60）， respectively， which were higher than 31.67% （19/60）， 61.67% （37/60）， and 68.33% （41/60） in the control group （χ2=5.763， 8.352， 10.208， P<0.05）. After treatment， the total effective rate of CT scanning in the observation group was 93.33% （56/60）， higher than 80.00% （48/60） in the control group （χ2=4.615， P<0.05）. The conversion rate to severe condition during hospitalization in the observation group was 3.33% （2/60）， lower than 15.00% （9/60） in the control group （χ2=4.904， P<0.05）. The readmission rate within 30 days after discharge in the observation group was 8.33% （5/60）， lower than 23.33% （14/60） in the control group （χ2=5.065， P<0.05）. No serious adverse drug reactions were observed in either group during the treatment period. ConclusionQimai Qinlou prescription can enhance immune function， alleviate inflammatory reactions， significantly relieve clinical symptoms， shorten the duration of the disease， improve the curative rate and CT scanning efficacy， prevent disease progression， reduce the readmission rate in the short term， and is clinically safe for the treatment of elderly patients with non-severe CAP with Qi and Yin deficiency and phlegm-heat obstructing lung syndrome. It is worthy of further research and application.
ABSTRACT
Objective To analyze the effect of immune function on the condition and prognosis of asthma in children with asthma. Methods A total of 148 children with asthma diagnosed in Qinghai women and children's Hospital from January 2018 to January 2021 were included in the analysis, the immune function of the children was determined, and the information of all children was followed up for 6 months after treatment; compared The condition and follow-up prognosis of children with immunocompromised and normal immune function were analyzed and discussed, and the correlation between the expression levels of immunoglobulins (IgG, IgA, IgM) and the condition and short-term recurrence prognosis (6 months) of children was analyzed and discussed, so as to guide Prevention and clinical work. Statistical analysis was done using SPSS19.0. Results The average age of 148 children with recurrent respiratory tract infection in the study was (8.94±3.65) years old, including 70 male children. The condition of the children was evaluated and classified into mild/severe cases: 148 children in this study included mild cases. There were 98 cases and 50 severe cases. There were more males and lower BMI levels in severe children (P<0.05) . The levels of IgG, IgA and IgM in children were all lower in severe children (P<0.05) . The follow-up found that the proportion of relapses in critically ill children was higher (P<0.05). Comparing the levels of IgG, IgA, and IgM in mild and severe children, the average levels of IgG, IgA, and IgM in severe children were lower than those in the mild group, and the difference was statistically significant (P<0.05); recurrence within 6 months of follow-up Prognostic evaluation showed that 19 of the 148 children had relapse, and the levels of IgG, IgA, and IgM in severe relapsed children were significantly lower than those without relapse (P<0.05). Analysis of the relevant factors potentially affecting the prognosis of recurrence showed that gender (female) (OR=1.726) , BMI level (weight loss) (OR=1.613) , IgG expression level factor (low expression) (OR=1.898) , IgA expression Level factor (low expression) (OR=3.509) , IgM expression level factor (low expression) (OR=3.217) and disease factor (severe) (OR=3.619) were potential risk factors, which would increase the risk of poor prognosis. Conclusion The asthma attack in children with immunocompromised immune function is relatively severe, and the short-term recurrence probability is higher, which deserves clinical attention and preventive intervention.
ABSTRACT
OBJECTIVES@#To study the effect of breastfeeding on immune function in infants with human cytomegalovirus (HCMV) infection.@*METHODS@#A retrospective analysis was performed on the medical data of 135 infants with HCMV infection who were admitted to Children's Hospital Affiliated to Zhengzhou University from January 2021 to May 2022, and all these infants received breastfeeding. According to the results of breast milk HCMV-DNA testing, the infants were divided into two groups: breast milk HCMV positive (n=78) and breast milk HCMV negative (n=57). According to the median breast milk HCMV-DNA load, the infants in the breast milk HCMV positive group were further divided into two subgroups: high viral load and low viral load (n=39 each). Related indicators were compared between the breast milk positive and negative HCMV groups and between the breast milk high viral load and low viral load subgroups, including the percentages of peripheral blood lymphocyte subsets (CD3+ T cells, CD3+CD4+ T cells, CD3+CD8+ T cells, and CD19+ B cells), CD4+/CD8+ ratio, IgG, IgM, IgA, and urine HCMV-DNA load.@*RESULTS@#There were no significant differences in the percentages of CD3+ T cells, CD3+CD4+ T cells, CD3+CD8+ T cells, and CD19+ B cells, CD4+/CD8+ ratio, IgG, IgM, IgA, and urine HCMV-DNA load between the breast milk HCMV positive and HCMV negative groups, as well as between the breast milk high viral load and low viral load subgroups (P>0.05).@*CONCLUSIONS@#Breastfeeding with HCMV does not affect the immune function of infants with HCMV infection.

OBJECTIVE@#To observe the effects of moxibustion on the stem cell factor (SCF)/tyrosine kinase receptor (c-kit) signaling pathway and immune function in rats with diarrhea irritable bowel syndrome (IBS-D), and to explore the mechanism of moxibustion for IBS-D.@*METHODS@#Among 52 young rats born from 6 healthy pregnant SPF rats, 12 rats were randomly selected into the normal group, and the remaining 40 rats were treated with the three-factor combination method of maternal separation, acetic acid enema and chronic restraint stress to establish the IBS-D rat model. Thirty-six rats with successful IBS-D model were randomly divided into a model group, a moxibustion group, and a medication group, 12 rats in each group. The rats in the moxibustion group were treated with suspension moxibustion at "Tianshu" (ST 25) and "Shangjuxu" (ST 37); the rats in the medication group were treated with intragastric administration of rifaximin suspension (150 mg/kg). All the treatments were given once a day for 7 consecutive days. The body mass, loose stool rate (LSR), the minimum volume threshold when abdominal withdrawal reflex (AWR) scored 3 were measured before acetic acid enema (35 days old), after modeling (45 days old), and after intervention (53 days old). After intervention (53 days old), HE staining was used to observe the morphology of colon tissue, and spleen and thymus coefficients were measured; ELISA method was used to detect serum inflammatory factors (tumor necrosis factor a [TNF-a], interleukin [IL]-10, IL-8), T-lymphocyte subsets (CD+4, CD+8, CD+45), value of CD+4/CD+8 and immune globulin (IgA, IgG, IgM); real-time PCR method and Western blot method was used to detect the expression of SCF, c-kit mRNA and protein in colon tissue; immunofluorescence staining method were used to detect positive expression of SCF and c-kit.@*RESULTS@#After intervention, compared with the normal group, in the model group, the body mass and the minimum volume threshold when AWR scored 3 were decreased (P<0.01), LSR, spleen and thymus coefficients, serum levels of TNF-α, IL-8, CD+4, CD+45, CD+4/CD+8, IgA, IgG, IgM were increased (P<0.01), serum IL-10 level and protein and mRNA expression of SCF and c-kit in colon tissue were decreased (P<0.01), and the positive expression of SCF and c-kit was decreased (P<0.01). Compared with the model group, in the moxibustion group and the medication group, the body mass and the minimum volume threshold when AWR scored 3 were increased (P<0.01, P<0.05), LSR, spleen and thymus coefficients, serum levels of TNF-α, IL-8, CD+4, CD+8, CD+45, CD+4/CD+8, IgA, IgG, IgM were decreased (P<0.01, P<0.05), serum IL-10 level and protein and mRNA expression of SCF and c-kit in colon tissue were increased (P<0.01), and the positive expression of SCF and c-kit was increased (P<0.01). Compared with the medication group, in the moxibustion group, the level of serum CD+4 was decreased (P<0.05), the value of CD+4/CD+8 was increased (P<0.01), and there was no significant difference in other indexes (P>0.05). The expression of SCF and c-kit mRNA was positively correlated with the minimum volume threshold when AWR scored 3 and IL-10 (P<0.01), and negatively correlated with remaining indexes (P<0.01, P<0.05).@*CONCLUSION@#Moxibustion could reduce visceral hypersensitivity, improve symptoms of abdominal pain and diarrhea in IBS-D rats, and its mechanism may be related to up-regulation of the expression of SCF/c-kit signaling pathway and improvement of IBS-D immune function.

Objective:To investigate the changes of inflammation and immune function in children with chronic tonsillitis after tonsillotomy. Methods:Prospectively collected 60 children with obstructive sleep apnea （OSA） diagnosed as chronic tonsillitis with adenoids and tonsillar hypertrophy from January to June 2021. Two groups were divided, the experimental group （n=30） underwent bilateral partial tonsillectomy + adenoidectomy by hypothermia plasma ablation, and the control group （n=30） underwent adenoidectomy by using the same hypothermia plasma ablation method. The number of tonsillitis attacks before surgery and within one year after surgery was recorded, and the serum immunoglobulin IgM, IgG, IgA, complement C3 and complement C4 levels before operation, one month and three months after operation were measured. Results:The number of tonsillitis attacks in the experimental group and the control group at one year after surgery was lower than that before surgery（P<0.05）; The number of inflammatory attacks in the experimental group was （0.50±0.63） times/year, which was lower than that of （1.33±0.80） times/year in the control group. There was no significant difference in the five immunization results of the two groups at one month and three months after operation compared with before operation, and there was also no significant difference between the experimental and the control groups. Conclusion:Partial tonsillectomy can be applied to children with chronic tonsillitis, which can effectively reduce the number of tonsillitis attacks and has no effect on the immune function of children.

ABSTRACT
Objective:To investigate the clinical application effects of leukocyte-filtered blood transfusions.Methods:A total of 120 patients with massive bleeding who received transfusions of a large amount of blood in the First People's Hospital of Yongkang, China from January 2017 to December 2018 were included in this study. They were divided into a control group (even numbers) and an observation group (odd numbers) according to registration numbers. The control group was subjected to direct blood transfusion. The observation group was given leukocyte-filtered blood transfusions. Coagulation function index, hemorheological index, cellular immune function, immunoglobulin level, body temperature, and the incidence of febrile non-hemolytic transfusion reactions were compared between the two groups.Results:After blood transfusions, prothrombin time, activated partial thromboplastin time, thrombin time in the observation group were (12.39 ± 1.41) seconds, (26.84 ± 6.47) seconds, and (14.32 ± 3.14) seconds, which were significantly shorter than those in the control group [(15.54 ± 2.03) seconds, (34.23 ± 7.59) seconds, (20.98 ± 4.27) seconds, t = 9.872, 5.740, 9.733, all P < 0.05]. Hematocrit, erythrocyte sedimentation rate, and plasma viscosity in the observation group were (39.28 ± 2.17)%, (25.97 ± 4.10) mm/h, and (2.19 ± 0.45) mp·s respectively, and those in the control group were (34.64 ± 4.52)%, (21.85 ± 3.64) mm/h, and (1.76 ± 0.42) mp·s respectively. There were significant differences in these indices between the two groups ( t = 9.87, 5.74, 9.73, all P < 0.05). There were significant differences in CD 3+, CD 4/CD 8, immunoglobulin G, immunoglobulin A, and immunoglobulin M between before and after blood transfusions in the control group ( t = 5.99, 5.91, 5.77, 5.80, 5.85, all P < 0.05). There were no significant differences in these indices between before and after blood transfusions in the observation group (all P > 0.05). After blood transfusions, body temperature was significantly lower in the observation group than in the control group [(36.58 ± 0.50) ℃ vs. (37.16±0.57)℃, t = 5.95, P < 0.05]. The incidence of febrile non-hemolytic transfusion reactions was significantly lower in the observation group than in the control group (1.67% vs. 13.33%, χ2 = 5.88, P < 0.05). Conclusion:Leukocyte-filtered blood transfusions can effectively restore the patient's body temperature to normal, improve coagulation function index and hemorheological index, reduce the impact of blood transfusions on the patient's immune function, and reduce febrile non-hemolytic transfusion reactions.

ABSTRACT
Objective:To study the effects of docetaxel, cisplatin and fluorouracil (TPF) regimen simultaneous intensity modulated radiotherapy (IMRT) on immune function and survival prognosis of patients with advanced esophageal cancer.Methods:A total of 93 patients with advanced esophageal cancer were screened in Hebei Veterans General Hospital from June 2015 to December 2017, and were divided into two groups using randomized envelope method. The observation group (47 cases) was given synchronous TPF regimen and IMRT, and the control group (46 cases) was given synchronous PF regimen (cisplatin combined with fluorouracil) and IMRT. Esophageal barium meal, chest and upper abdominal CT were reviewed within 1 month after treatment to assess the short-term efficacy and compare the immune function of the two groups before and after treatment. Kaplan-Meier survival curve was plotted to evaluate the long-term efficacy based on overall survival (OS). The incidence of adverse reactions in the two groups was collected to evaluate their safety.Results:After treatment, the T cell subgroup CD8 + level of the observation group was higher than that of the control group [(33.55±4.46)% vs. (29.06±3.61)%, P<0.05], while CD3 + [(51.29±5.22)% vs. (56.04±6.10)%, P<0.05], CD4 + [(28.27±3.63)% vs. (30.35±3.52)%, P<0.05] and CD4 + /CD8 + (0.84±0.25 vs. 1.04±0.08, P<0.05) levels were lower than those of the control group. The effective rate of recent treatment in the observation group was 82.98% (39/47), while the effective rate in the control group was only 63.04% (29/46), with a statistically significant difference ( χ2=4.70, P=0.030). The median OS of the observation group was 25.3 months (95% CI: 17.9-26.1), and that of the control group was 18.2 months (95% CI: 14.4-25.5), with a statistically significant difference ( χ2=3.28, P=0.038). Adverse reactions during the follow-up period of the two groups of patients were mainly nausea/vomiting, fatigue, anorexia, hematological toxicity, esophagitis and pneumonia, etc., which were mostly grade 1-2, and disappeared after symptomatic treatment or termination of treatment. Compared with the control group, the incidence of nausea/vomiting (46.81% vs. 78.26%, χ2=9.80, P=0.002), anorexia (44.86% vs. 71.74%, χ2=6.99, P=0.008), leukopenia (36.96% vs. 73.91%, χ2=13.37, P<0.001) and esophagitis (61.70% vs. 82.61%, χ2=5.05, P=0.025) adverse reactions was lower in the observation group. Conclusion:TPF combined with IMRT has high efficacy and low adverse reactions, which can be used as an effective treatment to improve the survival prognosis of patients with advanced esophageal cancer.
ABSTRACT
Objective:To investigate the effects of supplemental parenteral nutrition on postoperative nutritional status, immune function and inflammatory response in patients with esophageal cancer after operation.Methods:A prospective study was performed on 72 patients with esophageal cancer who visited the Department of Thoracic and Cardiovascular Surgery of the Affiliated Hospital of Putian University from June 2018 to June 2020. According to the random table of new drug data statistics and processing software, they were randomly divided into experimental group (supplementary parenteral nutrition group) and the control group (complete enteral nutrition group), with 36 cases in each group. The experimental group was given enteral nutrition (EN) from the first day after operation, and EN and parenteral nutrition (PN) was given on the 4th to 8th day after operation.
