Résumé

ObjectiveTo evaluate the clinical efficacy of modified Houpo Dahuangtang in moderate and severe acute respiratory distress syndrome (ARDS) patients with phlegm-heat accumulation,and monitor the pulmonary ventilation changes of patients before and after treatment by electrical impedance tomography(EIT). MethodThe 62 cases of moderate and severe ARDS patients with phlegm-heat accumulation who required mechanical ventilation in the department of intensive care unit (ICU) in Chongqing Hospital of Traditional Chinese Medicine from September 2021 to June 2022 were selected,and divided into an experimental group(31 cases)and a control group(31 cases)using a random number table. On the basis of regular Western medicine treatment,the experimental group received modified Houpo Dahuangtang and the control group received warm water by a nasogastric tube for seven days. The changes in the clinical efficacy of traditional Chinese medicine(TCM),the oxygenation index[arterial oxygen partial pressure (PaO2)/fractional inspired oxygen(FiO2),P/F],lactic acid(Lac),acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ) score,compliance,plateau pressure,gas distribution parameters monitored by EIT(Z1,Z2,Z3 and Z4),inflammatory factors[interleukin-6 (IL-6),IL-10, tumor necrosis factor-α (TNF-α) and C-reactive protein (CRP)] of both groups before and after treatment were recorded. Besides, the mechanical ventilation time, length of stay in ICU, 28-day mortality and incidence of adverse reactions(delirium,abdominal pain and diarrhea)in the two groups were also observed. ResultThere was no significant difference in the baseline indexes of patients in the two groups,and thus the two groups were comparable. After treatment for one week, the total effective rate for TCM syndromes in the experimental group was 90.30%(28/31), higher than the 67.74%(21/31)in the control group(Z=-2.415,P<0.05).Compared with the same group before treatment, the plateau pressure and Lac decreased (P<0.01)and the compliance and P/F increased (P<0.01) in experimental group, while the Lac decreased (P<0.05)and the P/F increased (P<0.05), and the compliance and plateau pressure did not change significantly in the control group. After treatment,the plateau pressure and inflammatory factors in the experimental group were lower than those in the control group(P<0.05), but the compliance and P/F in the experimental group were higher than those in the control group(P<0.05), and the gas distribution parameters Z1,Z2,Z3,Z4,Z1+Z2,and Z3+Z4 monitored by EIT in the experimental group were all higher than those in the control group (P<0.05). There was no significant difference in mechanical ventilation time, ICU hospitalization time, 28-day mortality, delirium, abdominal pain, diarrhea and other adverse reactions between the two groups. ConclusionModified Houpo Dahuangtang can significantly improve the P/F,pulmonary ventilation in gravity-dependent regions and pulmonary compliance,reduce the release of inflammatory factors in moderate and severe ARDS patients. Compared with conventional methods,EIT can timely monitor the pulmonary ventilation changes in ARDS patients,which suggests its clinical feasibility.

Résumé

OBJECTIVE To study the effects of Phellodendron amurense polysaccharides (PAP) on improving gouty nephropathy (GN) in rats, and to investigate its mechanism primarily by interfering the p38 mitogen-activated protein kinase (p38 MAPK)/nuclear factor-κB(NF-κB)/tumor necrosis factor-α(TNF-α). METHODS Sixty rats were randomly divided into normal group (water), model group (water), allopurinol group (positive control, 20 mg/kg), PAP high-dose, medium-dose and low-dose groups (100, 50, 25 mg/kg, by raw material) after being stratified by body weight, with 10 rats in each group. Except for the normal group, the other groups were induced to construct GN model by giving 1 500 mg/kg potassium oxazinate and 100 mg/kg adenine intragastrically for 14 days. After modeling, the rats in each group were given relevant medicine/water intragastrically, once a day, for consecutive 28 days. After the last medication, the levels of biochemical parameters related to renal function [uric acid, creatinine (Cr), blood urea nitrogen (BUN), xanthine oxidase (XOD)] were detected in rats, and the histopathological changes in the rat kidney were observed. The protein expressions of monocyte chemoattractant protein-1(MCP-1),TNF-α and interleukin-6(IL-6) as well as the phosphorylation levels of p38 MAPK and NF-κB p65 protein were determined in renal tissue of rats. RESULTS Compared with the normal group, the model group suffered from the dilatation of renal tubules, structural damage to glomeruli, accompanied by inflammatory infiltration and fibrosis; the contents of uric acid, Cr, BUN and XOD, the protein expressions of MCP-1,TNF-α and IL-6 and the phosphorylation levels of p38 MAPK and NF-κB p65 protein were all increased significantly (P<0.05 or P<0.01). Compared with the model group, the pathological symptoms of renal tissue in rats had been improved to varying degrees in different dose groups of PAP; the contents of uric acid, Cr, BUN and XOD, protein expressions of MCP-1, TNF-α and IL-6, the phosphorylation levels of p38 MAPK and NF-κB p65 protein in PAP high-dose and PAP medium-dose groups were all decreased significantly (P<0.05 or P<0.01). CONCLUSIONS PAP exhibits an anti-GN effect, the mechanism of which may be associated with inhibiting the p38 MAPK/NF-κB/TNF-α signaling pathway.

Résumé

BackgroundBariatric surgery has emerged as an important tool in the management of obesity. Some patients undergoing bariatric surgery are prone to develop emotional abnormalities and have abnormally elevated concentrations of inflammatory factors level in peripheral blood, whereas current domestic research focusing on the impact of preoperative emotional states and peripheral blood inflammatory factors level on weight loss effect remains limited. ObjectiveTo explore the correlation of preoperative emotional abnormalities with the effectiveness of bariatric surgery in obese patients, and to provide theoretical basis for improving the clinical efficacy of bariatric surgery. MethodsEighty-one obese patients scheduled for bariatric surgery at gastrointestinal surgery Department of West China Hospital, Sichuan University from December 30, 2022 to June 30, 2023 were enrolled and assessed using Hamilton Depression Scale-17 item (HAMD-17) and Hamilton Anxiety Scale (HAMA). Patients who scored 7 or above on HAMD-17 or HAMA or had a history of previous depression or anxiety diagnoses were classified into emotional abnormality group (n=34), and samples who scored less than 7 on HAMD-17 and HAMA and were free of history of previous depression and anxiety diagnoses were set as non-emotional abnormality group (n=47). The data were collected by the self made questionnaire. Patients were subjected to complete the assessment of Beck Scale for Suicide Ideation-Chinese Version (BSI-CV), Eating Disorder Inventory (EDI) and Pittsburgh Sleep Quality Index (PSQI). Laboratory tests including peripheral blood C-reactive protein (CRP) and interleukin-6 (IL-6). Body weight and height assessed in the early morning after an overnight fasting period were recorded in all participants at 1- and 6-month after surgery through outpatient clinic visits or telephone follow-up. Pearson correlation coefficient was used to examine relationship among body mass index (BMI), preoperative emotional states and peripheral blood inflammation mediators. ResultsAmong 81 obese patients, 62 completed the study, including 27 cases in emotional abnormality group and 35 cases in non-emotional abnormality group. Emotional abnormality group scored higher on BSI-CV (current), BSI-CV (worst), EDI and PSQI, and detected higher levels of CRP and IL-6 compared with non-emotional abnormality group (Z=2.677, 2.975, t=3.573, 4.035, 1.990, 2.799, P<0.05 or 0.01). For BMI, there was no significant group effect and time×group interaction effect (P>0.05), but a significant time effect (F=227.740, P<0.01). Within emotional abnormality group, BMI at the baseline, 1- and 6-month after surgery showed a positive correlation with IL-6 level (r=0.419, 0.510, 0.559, P<0.05 or 0.01), BMI at 6-month after surgery was positively correlated with HAMD-17 total score (r=0.390, P<0.05), and ΔBMI% at 6-month after surgery was negatively correlated with HAMD-17 total score (r=-0.421, P<0.05). Within non-emotional abnormality group, baseline BMI was positively correlated with IL-6 level (r=0.338, P<0.01). ConclusionThe short-term effect of bariatric surgery may be comparable in obese patients with or without emotional abnormalities, while it cannot be ruled out whether the outcome of bariatric surgery is related to the severity of preoperative depression.

Résumé

OBJECTIVE@#To investigate the effects of Danmu Extract Syrup (DMS) on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice and explore the mechanism.@*METHODS@#Seventy-two male Balb/C mice were randomly divided into 6 groups according to a random number table (n=12), including control (normal saline), LPS (5 mg/kg), LPS+DMS 2.5 mL/kg, LPS+DMS 5 mL/kg, LPS+DMS 10 mL/kg, and LPS+Dexamethasone (DXM, 5 mg/kg) groups. After pretreatment with DMS and DXM, the ALI mice model was induced by LPS, and the bronchoalveolar lavage fluid (BALF) were collected to determine protein concentration, cell counts and inflammatory cytokines. The lung tissues of mice were stained with hematoxylin-eosin, and the wet/dry weight ratio (W/D) of lung tissue was calculated. The levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-6 and IL-1 β in BALF of mice were detected by enzyme linked immunosorbent assay. The expression levels of Claudin-5, vascular endothelial (VE)-cadherin, vascular endothelial growth factor (VEGF), phospho-protein kinase B (p-Akt) and Akt were detected by Western blot analysis.@*RESULTS@#DMS pre-treatment significantly ameliorated lung histopathological changes. Compared with the LPS group, the W/D ratio and protein contents in BALF were obviously reduced after DMS pretreatment (P<0.05 or P<0.01). The number of cells in BALF and myeloperoxidase (MPO) activity decreased significantly after DMS pretreatment (P<0.05 or P<0.01). DMS pre-treatment decreased the levels of TNF-α, IL-6 and IL-1 β (P<0.01). Meanwhile, DMS activated the phosphoinositide 3-kinase/protein kinase B (PI3K/Akt) pathway and reversed the expressions of Claudin-5, VE-cadherin and VEGF (P<0.01).@*CONCLUSIONS@#DMS attenuated LPS-induced ALI in mice through repairing endothelial barrier. It might be a potential therapeutic drug for LPS-induced lung injury.

Résumé

SUMMARY: The 12C6+ heavy ion beam irradiation can cause bystander effects. The inflammatory cytokines, endocrine hormones and apoptotic proteins may be involved in 12C6+ irradiation-induced bystander effects. This study characterized the protective effects and mechanisms of Huangqi decoction (HQD) against 12C6+ radiation induced bystander effects. Wistar rats were randomly divided into control, 12C6+ heavy ion irradiation model, and high-dose/medium-dose/low-dose HQD groups. HE staining assessed the pathological changes of brain and kidney. Peripheral blood chemical indicators as well as inflammatory factors and endocrine hormones were detected. Apoptosis was measured with TUNEL. Proliferating cell nuclear antigen (PCNA) expression was determined with real-time PCR and Western blot.Irradiation induced pathological damage to the brain and kidney tissues. After irradiation, the numbers of white blood cells (WBC) and monocyte, and the expression of interleukin (IL)-2, corticotropin-releasing hormone (CRH) and PCNA decreased. The damage was accompanied by increased expression of IL-1β, IL-6, corticosterone (CORT) and adrenocorticotropic hormone (ACTH) as well as increased neuronal apoptosis. These effects were indicative of radiation-induced bystander effects. Administration of HQD attenuated the pathological damage to brain and kidney tissues, and increased the numbers of WBC, neutrophils, lymphocyte and monocytes, as well as the expression of IL-2, CRH and PCNA. It also decreased the expression of IL-1β, IL-6, CORT and ACTH as well as neuronal apoptosis. HQD exhibits protective effects against 12C6+ radiation-induced bystander effects. The underlying mechanism may involve the promotion of the production of peripheral blood cells, inhibition of inflammatory factors and apoptosis, and regulation of endocrine hormones.


La irradiación con haz de iones pesados 12C6+ puede provocar efectos secundarios. Las citoquinas inflamatorias, las hormonas endocrinas y las proteínas apoptóticas pueden estar involucradas en los efectos secundarios inducidos por la irradiación 12C6+. Este estudio caracterizó los efectos y mecanismos protectores de la decocción de Huangqi (HQD) contra los efectos externos inducidos por la radiación 12C6+. Las ratas Wistar se dividieron aleatoriamente en grupos control, modelo de irradiación de iones pesados 12C6+ y grupos de dosis alta/media/baja de HQD. La tinción con HE evaluó los cambios patológicos del cerebro y el riñón. Se detectaron indicadores químicos de sangre periférica, así como factores inflamatorios y hormonas endocrinas. La apoptosis se midió con TUNEL. La expresión del antígeno nuclear de células en proliferación (PCNA) se determinó mediante PCR en tiempo real y transferencia Western blot. La irradiación indujo daños patológicos en los tejidos cerebrales y renales. Después de la irradiación, disminuyó el número de glóbulos blancos (WBC) y monocitos, y la expresión de interleucina (IL)-2, hormona liberadora de corticotropina (CRH) y PCNA. El daño estuvo acompañado por una mayor expresión de IL-1β, IL-6, corticosterona (CORT) y hormona adrenocorticotrópica (ACTH), así como un aumento de la apoptosis neuronal. Estas alteraciones fueron indicativas de efectos inducidos por la radiación. La administración de HQD atenuó el daño patológico a los tejidos cerebrales y renales, y aumentó el número de leucocitos y monocitos, así como la expresión de IL-2, CRH y PCNA. También disminuyó la expresión de IL-1β, IL-6, CORT y ACTH, así como la apoptosis neuronal. HQD exhibe mecanismos protectores contra los efectos externos inducidos por la radiación 12C6+. El mecanismo subyacente puede implicar la promoción de la producción de células sanguíneas periféricas, la inhibición de factores inflamatorios y la apoptosis y la regulación de hormonas endocrinas.

Résumé

Purpose: To study ocular surface signs, symptoms, and tear film composition following prophylactic thermal pulsation therapy (TPT) prior to refractive surgery, and to compare these outcomes with those who underwent TPT after refractive surgery. Methods: Patients with mild?to?moderate evaporative dry eye disease (DED) and/or meibomian gland dysfunction (MGD) undergoing refractive surgery were included. Group 1 patients received TPT (LipiFlow) prior to laser?assisted in situ keratomileusis (LASIK; n = 32, 64 eyes), and Group 2 patients received TPT three months after LASIK (n = 27, 52 eyes). Ocular Surface Disease Index (OSDI) score, Schirmer’s test (ST1, ST2), Tear Breakup Time (TBUT), meibography, and tear fluid were obtained preoperatively and at three months postoperatively in Groups 1 and 2. Additional postoperative evaluation was performed three months after TPT in Group 2. Tear soluble factor profile was measured by multiplex enzyme?linked immunosorbent assay (ELISA) using flow cytometry. Results: Postoperative OSDI score was significantly lower and TBUT was significantly higher when compared with matched preoperative values of Group 1 participants. On the other hand, the postoperative OSDI score was significantly higher and TBUT significantly lower when compared with matched preoperative values of Group 2 participants. TPT significantly reduced the postoperative elevation in OSDI and significantly reduced the postoperative reduction in TBUT in Group 2 participants. Tear Matrix metalloproteinase?9/ Tissue inhibitor matrix metalloproteinase 1 (MMP?9/TIMP1) ratio was significantly higher, postoperatively, when compared with matched preoperative levels in Group 2. However, MMP9/TIMP1 ratio remained unaltered in Group 1 participants. Conclusion: TPT prior to refractive surgery improved postsurgical ocular surface signs and symptoms and reduced tear inflammatory factors, thereby suggesting the plausibility of reduced post?refractive surgery DED in patients.

Résumé

ObjectiveTo explore the effect and possible mechanism of electroacupuncture (EA) at Fenglong (ST40) on liver lipid synthesis and insulin resistance (IR) in hyperlipidemic (HLP) rats. MethodEighteen rats were randomly divided into three groups, blank group, model group, and EA group, each consisting of six rats. The blank group rats were with fed a basic diet, while those in the model group and EA group were fed high-fat diet for 8 weeks. After modeling, the rats in the EA group received bilateral EA treatment at “Fenglong” (ST 40). The rats in the model group underwent daily binding treatment, once a day, continuously 5 days a week, for a total of 4 weeks. Following the intervention, the levels of triglycerides (TG) and free fatty acids (FFA) in liver tissue was determined using ELISA. Serum TG, FFA, fasting insulin (FINS), alanine transaminase (ALT), aspartate Transaminase (AST), tumor necrosis factor-ɑ (TNF-ɑ)and interleukin 6 (IL-6) were also measured. The fasting plasma glucose (FBG) assessed using a glucose meter and the homeostatic model assessment of insulin resistance (HOMA-IR) was calculated. Liver pathology was examined through HE staining and oil red O staining. The expression of hepatic sterol regulator binding protein 1c (SREBP1c), recombinant fatty acid synthase (FASN) and stearoyl-CoA desaturase 1 (SCD1) were detected through immunofluorescence. The protein expression levels of liver insulin receptor substrate 1 (IRS1) and tyrosine-phosphorylated insulin receptor substrate 1 (p-IRS1-Tyr) were determined via Western blot. ResultsWhen compared to the blank group, the model group of rats exhibited elevated serum and liver tissue levels of TG and FFA, as well as increased serum levels of AST, ALT, TNF-α, IL-6, FBG, FINS, and HOMA-IR (P<0.05). HE staining revealed disordered arrangements of liver cells, indicating widespread fatty degeneration. Oil red O staining showed abundant bright red lipid droplets within liver cell cytoplasm, indicating severe lipid accumulation. The average fluorescence intensity of SREBP1c, FASN, and SCD1 in liver tissue significantly increased (P<0.05), while p-IRS1-Tyr protein expression levels significantly decreased (P<0.05). In comparison to the model group, the EA group of rats showed significantly reduced serum and liver tissue levels of TG and FFA, along with decreased serum levels of AST, ALT, TNF-α, IL-6, FBG, FINS, and HOMA-IR (P<0.05). HE staining indicated more regular arrangements of liver cells, and oil red O staining revealed a significant reduction in liver cell lipid droplets, indicating a less severe degree of lipid accumulation. The average fluorescence intensity of SREBP1c, FASN, and SCD1 in liver tissue significantly decreased (P<0.05), while p-IRS1-Tyr protein expression levels significantly increased (P<0.05), with no significant difference in IRS1 protein expression (P>0.05). ConclusionEA at “Fenglong” (ST 40) can significantly decrease serum lipid in HLP rats, improves liver fat accumulation, and also ameliorate insulin resistance. The mechanism may be related to the inhibition of hepatic lipid synthesis molecule expression, reduced serum inflammatory factors, and an increase in insulin substrate receptor phosphorylation levels.

Objective To explore the relationship between serum levels of tyrosine hydroxylase (TH) and the risk of cerebral infarction in Parkinson's patients. Methods A total of 129 patients with confirmed Parkinson's disease who were hospitalized in our hospital were selected, among the 58 patients had Parkinson's disease complicated with cerebral infarction (complicated with cerebral infarction group), and the remaining 71 patients had Parkinson's disease alone (control group). Blood TH levels and other potential related information were collected retrospectively at the time of diagnosis. Comparative analysis of data was performed using SPSS software. Results Comparing the serum TH expression levels in patients with Parkinson's disease and patients with cerebral infarction at admission , the serum TH level in patients with cerebral infarction was lower. Results also showed that the levels of CRP, IL-6, MDA, and Hcy were higher in patients with cerebral infarction, while PON-1 level was lower. In addition, patients with cerebral infarction had lower motor ability (higher UPDRS Ⅲ score). Further regression analysis was carried out with the occurrence of Parkinson's disease complicated with cerebral infarction as the dependent variable and the potential influencing factors as the independent variable. The results indicated that factors such as low expression of TH, high expression of inflammatory factors, and high expression of oxidative stress factors were positively correlated with the risk of complications of the two diseases. Conclusion The low expression of TH, inflammatory state and high oxidative stress state are the potential risk factors for Parkinson's disease complicated with cerebral infarction, which deserves clinical attention.

@#Objective To investigate the effect of cold stimulation on the phenotype of alveolar macrophages(MH-S cells) in mice. Methods MH-S cells were cultured at 37 ℃ for 24 h,and cold stimulated at 36,34 and 32 ℃ for 0,0. 5,1,3,6,9 and 12 h respectively. The mRNA transcription levels of interleukin-1β(IL-1β) and interleukin-10(IL-10) genes in MH-S cells were detected by qRT-PCR. MH-S cells were cultured at 37 ℃ for 24 h,and cold stimulated at 34 ℃ for 0. 5 h,which were detected for the mRNA transcription levels of tumor necrosis factor-α(TNF-α),inducible nitric oxide synthase(iNOS)and Arginase1(Arg1)genes by qRT-PCR(MH-S cells with 0 h cold stimulation as control),detected for the expression of iNOS and Arg1 by immunofluorescence assay(MH-S cells cultured at 37 ℃ for 0. 5 h as negative control)and detected for the expression levels of iNOS,TNF-α and nuclear factor-kappa B(NF-κB)by Western blot(MH-S cells cultured at 37 ℃ for 0. 5 h as negative control). Results The mRNA transcription levels of IL-1β and IL-10 genes in MH-S cells were the highest when the cells were cultured at 34 ℃ for 0. 5 h,therefore,the cold stimulation model of MH-S cells was established under this condition. Compared with the cells cultured for 0 h,the mRNA transcription levels of iNOS,TNF-α and Arg1genes in MH-S cells cultured at 34 ℃ for 0. 5 h increased significantly(t = 3. 733,12. 190 and 6. 793,respectively,each P < 0. 05). Compared with the negative control group,the fluorescence expression intensity of iNOS and Arg1 in MH-S cells in the stimulation group increased,especially iNOS,the expression levels of iNOS and TNF-α proteins increased with no significant difference(t = 0. 675 and 1. 514,respectively,each P > 0. 05),and the expression level of NF-κB increased significantly(t = 3. 092,P < 0. 05). Conclusion Cold stimulation at 34 ℃ for 0. 5 h can increase the expression of inflammatory factors such as IL-1β,IL-10,TNF-α,iNOS,Agr1 and NF-κB in MH-S cells,activate NF-κB signaling pathway in MH-S cells,induce the expression of inflammatory proteins and promote cell activation.

Résumé

Objective:To observe any effect of ultrashortwave (USW) therapy on inflammatory cytokines and the MAPK pathway of rats with a spinal cord injury.Methods:Seventy-nine Sprague-Dawley rats were randomly divided into a control group ( n=35), an intervention group ( n=35) and a sham group ( n=9). Allen′s method was used to establish a contusion model of SCI in the rats of the control and intervention groups, while the sham group′s spinal tissues were exposed but not stricken. Beginning twenty-four hours after SCI modeling, the intervention group was given 7min of USW therapy daily, five days a week till the day of sacrifice for sampling the target area of spinal cord for tests. Then, motion function was evaluated using Basso, Beattie and Bresnahan (BBB) scoring. One, three and seven days after the SCI modeling, immunofluorescence and western blotting were employed to observe any changes in inflammatory factors and the MAPK pathway in the lesioned area. Results:Fourteen days after the modeling the average BBB score of the intervention group was significantly higher than the control group′s average. Moreover, 7 days after the modeling the average content of the domains containing protein 3 (NLRP3), interleukin-6 (IL-6), IL-6 receptor and tumor necrosis factor-α (TNF-α) in the target area of the spinal cord of sham group showed significantly lower levels than in the other 2 groups. And the levels in the intervention group were significantly lower than in the control group. Seven days after the modeling the number of cells positive for zinc finger protein 36 (TTP) in the lesioned area of the intervention group was significantly greater than among the control group. At the same time the levels of MAPK-activated protein kinase 2 (MK2), phosphorylated-mitogen-activated protein kinase-activated version (p-MK2) and TTP in the control and intervention groups were significantly higher than in the sham group. And there were significant differences between the intervention group and control group in the levels of MK2, p-MK2 and TTP.Conclusion:Ultrashortwave therapy can inhibit inflammation by regulating the MAPK inflammatory pathway, promoting the recovery of motion functions, at least in rats.

OBJECTIVE@#To observe the effects of transcutaneous acupoint stimulation (TEAS) on sleep quality and inflammatory factor in frail elderly patients undergoing laparoscopic colorectal cancer surgery.@*METHODS@#A total of 100 frail elderly patients undergoing elective laparoscopic colorectal cancer surgery were randomly divided into an observation group and a control group, 50 cases in each one. Patients in the observation group received TEAS, 30 min before surgery until the end of surgery, at 18:00 on the day of surgery and on the 1st, 2nd and 3rd day after surgery (30 min each time). TEAS was delivered at bilateral Neiguan (PC 6), Shenmen (HT 7) and Hegu (LI 4). The disperse-dense wave of 2 Hz/100 Hz was selected, and the maximal stimulation intensity depended on patient's tolerance. The operation procedure in the control group was same as the observation group, but without electric stimulation exerted. The 1st day before surgery and on the 1st, 3rd and 7th day after surgery, the scores of Pittsburgh sleep quality index (PSQI) and Athens insomnia scale (AIS), as well as the serum levels of C reactive protein (CRP) and interleukin-6 (IL-6) were observed in the patients of two groups. At 24 h, 48 h and 72 h after surgery, the score of pain visual analogue scale (VAS) was recorded in the two groups, as well as the pressing times of analgesic pump and the usage of flurbiprofen axetil during analgesic stage. The occurrence of post operative adverse reactions was observed in the patients of two groups.@*RESULTS@#On the 1st and 3rd day after surgery, except the usage of hypnotic drug scores, the scores of each item and the total scores of PSQI, as well as AIS scores were all increased in the two groups compared with those of 1 day before surgery (P<0.05); and the scores in the observation group were lower than those in the control group (P<0.05). On the 7th day after surgery, the scores of each item and the total scores of PSQI, and AIS scores were not different statistically in comparison between the two groups (P>0.05). On the 1st, 3rd and 7th day after surgery, serum levels of CRP and IL-6 were all increased in the patients of two groups when compared with those of 1 day before surgery (P<0.05), serum levels CRP and IL-6 in the patients of the observation group were lower than those of the control group (P<0.05). The VAS scores of 24 h, 48 h and 72 h after surgery, the pressing times of analgesic pump, the frequency and dosage of the remedies were not different statistically between the two groups (P>0.05).@*CONCLUSION@#TEAS can effectively improve sleep quality and reduce inflammatory reaction in frail elderly patients undergoing laparoscopic colorectal cancer surgery.

OBJECTIVE@#To compare the clinical efficacy on cervical spondylosis of nerve root type with qi stagnation and blood stasis treated with warming needle with different lengths of moxa stick.@*METHODS@#Six hundred patients with cervical spondylosis of nerve root type with qi stagnation and blood stasis were randomly divided into 4 groups: a 4 cm length group (150 cases, 5 cases dropped off, 2 cases suspended), a 3 cm length group (150 cases, 6 cases dropped off, 2 cases suspended), a 2 cm length group (150 cases, 6 cases dropped off), and a routine acupuncture group (150 cases, 6 cases dropped off). Warming needle with moxa stick in the length of 4 cm, 3 cm and 2 cm was delivered in the 4 cm length group, the 3 cm length group and the 2 cm length group, respectively. In the routine acupuncture group, simple acupuncture was applied. The acupoints selected in the above groups included Dazhui (GV 14) and bilateral Jiaji (EX-B 2) of C5 and C7, Fengchi (GB 20), Jianzhen (SI 9), Quchi (LI 11), Zhongzhu (TE 3), etc. In each group, the intervention was delivered once daily and 5 times a week. One course of intervention was composed of 2 weeks and 2 courses were required. The TCM syndrome score, the score of clinical assessment scale for cervical spondylosis (CASCS), the score of the brachial plexus traction test of the affected upper limb, F wave occurrence rate and conduction velocity of the ulnar nerve, the median nerve and the radial nerve of the affected upper limb were compared before and after treatment in the patients of each group. The levels of serum inflammatory factors, i.e. interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor α (TNF-α) and hypersensitive C-reactive protein (hs-CRP), were measured before and after treatment in the patients of each group. The clinical cfficacy was evaluated in the 4 groups.@*RESULTS@#After treatment, the results of TCM syndrome evaluation, i.e. the scores of neck pain, activity limitation and upper limb numbness and pain, as well as the total scores; and the scores of brachial plexus traction test were reduced when compared with those before treatment in each group (P<0.01, P<0.05). The scores of subjective symptoms and adaptability, and the total scores of CASCS were elevated in comparison with those before treatment in each group (P<0.01, P<0.05). In the 4 cm length group, compared with the other 3 groups, the scores of neck pain and activity limitation for TCM syndrome evaluation, and its total score were lower (P<0.05, P<0.01); and the scores of subjective symptoms and adaptability, and the total score of CASCS were higher (P<0.05, P<0.01). The score of the brachial plexus traction test in the 4 cm length group was lower than that of the routine acupuncture group (P<0.05). After treatment, F wave occurrence rates and conduction velocity of median nerve and radial nerve were increased when compared with those before treatment in each group (P<0.05, P<0.01). F wave occurrence rate and conduction velocity of the radial nerve in the 4 cm length group were higher than those of the other 3 groups (P<0.05), and those of the median nerve were higher when compared with the routine acupuncture group (P<0.05). After treatment, the levels of serum IL-1β, IL-6 and TNF-α were all reduced when compared with those before treatment in each group (P<0.01, P<0.05); the level of serum IL-6 in the 4 cm length group was lower than those of the other 3 groups and serum level of TNF-α was lower compared with that in the routine acupuncture group (P<0.05). The total effective rate of the 4 cm length group was 78.3% (112/143), which was higher when compared with the 3 cm length group (67.6%, 96/142), the 2 cm length group (65.3%, 94/144) and the routine acupuncture group (53.5%, 77/144), respectively (P<0.05).@*CONCLUSION@#Warming needle with moxa stick of 4 cm in length effectively relieves the clinical symptoms of cervical spondylosis of nerve root type with qi stagnation and blood stasis, improves the nerve function of the upper limbs, and reduces the inflammatory responses caused by nerve compression. The clinical efficacy of this therapy with moxa stick of 4 cm in length is superior to the warming needle with moxa sticks of 3 cm and 2 cm, as well as the routine acupuncture.

@#Abstract: Objective To analyze the effect of adjuvant to levofloxacin in the treatment of retreatment smear positive pulmonary tuberculosis, as well as its effect on respiratory function, immune function and inflammatory factors. Methods One hundred cases of retreatment smear positive pulmonary tuberculosis patients admitted to Rudong County People's Hospital in Nantong city in Jiangsu province from 2017 to 2021 were randomly divided into a control group (n=50) and an observation group (n=50) according to random number table method. Both groups received conventional treatment (3 months of isoniazid, rifampicin, ethambutol, pyrazinamide / 6 months of isoniazid, rifampicin, ethambutol), with levofloxacin added to the control group, and thymopentin added to the observation group for the first three months in addition to routine treatment. The treatment effect of the two groups were compared. Results The sputum smear conversion rate of the observation group was significantly higher than that of the control group after 3 months and 5 months of treatment (χ2=7.142, P<0.05; χ2=6.250, P<0.05). The cavity absorption time and lesion absorption time in the observation group were significantly lower than those in the control group (t=4.006, P<0.05; t=5.165, P<0.05). The turning time of bacteriological culture in the observation group was significantly lower than that in the control group (t=4.220,P<0.05). After 3 months of treatment, CD4+, CD3+, CD4+/CD8+ of the observation group were higher than those of the control group, the differences were statistically significant (t=8.885, P<0.05; t=6.274, P<0.05; t=4.357, P<0.05). After 3 months of treatment, the IFN-γ (interferon-γ) of the observation group was higher than that of the control group (t=8.892, P<0.05), whereas the , IL-10 (interleukin-10) was significantly lower than that in the control group (t=5.986, P<0.05). After 3 months of treatment, forced vital capacity (FVC), forced expiratory volume in one second (forced expiratory volume in one second, FEV 1) and the one-second rate (forced expiratory volume in one second / forced vital capacity, FEV1/FVC) in the observation group were significantly higher than those in the control group (t=11.223, P<0.05; t=10.128, P<0.05; t=4.464, P<0.05). There was no statistically significant difference in the incidence of adverse reactions between the two groups (χ2=0.378, P>0.05). Conclusions Thymopentin combined with levofloxacin had a significant application effect in the treatment of retreatment smear positive pulmonary tuberculosis, s, which led to improved inflammatory reaction, respiratory function and immune function.

OBJECTIVE To investigate the effect and mechanism of total flavonoids of Bidens pilosa L. (TFB) on lipopolysaccharide (LPS)-induced neuroinflammation in mice. METHODS Fifty C57BL/6 mice were randomly divided into normal control group, LPS group and TFB low-dose, medium-dose and high-dose groups, with 10 mice in each group. TFB low-dose, medium-dose and high-dose groups were given TFB solution intragastrically at 60, 120 and 240 mg/kg, and the normal control group and LPS group were given corresponding volume of normal saline, once a day, for consecutive 21 d. From the 15th day of administration, except for the normal control group, other groups were given LPS (400 μg/kg) intraperitoneally for 7 consecutive days to establish neuroinflammatory model. Brain tissues were taken under anesthesia 4 h after the final administration. The morphological changes of neuronal cells in mice were observed; the contents of nitric oxide (NO), tumor necrosis factor α (TNF- α), interleukin-1β (IL-1β), IL-6 and IL-10 were measured, and the expressions of inflammatory pathway-related proteins [inducible NO synthase (iNOS), cyclooxygenase-2 (COX-2), myeloid differentiation factor 88 (Myd88) and protein kinase C (PKC)] were measured in the brain tissues of mice. RESULTS Compared with the normal control group, the neuronal arrangement in the hippocampal region of the brain tissue of mice in the LPS group was sparsely disorganized, with a large number of neuronal fixations and shrunken nuclei; the contents of TNF-α, IL-1β, IL-6 and NO in the brain tissue were significantly increased, the contents of IL-10 were significantly decreased, and the relative expressions of iNOS, COX-2, Myd88 and PKC proteins were significantly increased (P<0.05). Compared with the LPS group, the neuronal pathological changes in the brain tissue of mice in the TFB low-dose, medium-dose and high-dose groups were 202014810) significantly improved, and the changes of the above indices in the brain tissue were significantly reversed (P<0.05) CONCLUSIONS TFB has an inhibitory effect on E-mail:pangxjun@163.com neuroinflammation, and its mechanism of action may be related to down-regulation of the expressions of inflammatory pathway-related proteins iNOS, COX-2, Myd88 and PKC, and reduction of inflammatory factors release.

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.

ObjectiveTo investigate the regulatory effect of Mankuining Formula (MKNF) on the gut microbiota and the NOD-like receptor (NLR)P3/Caspase-1/gasdermin D (GSDMD) pyroptosis pathway-mediated inflammation in dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) mice. MethodSixty SPF C57BL/6 mice were randomly divided into a blank group, a model group, a MKNF group (20 g·kg-1), and a mesalazine group (0.266 g·kg-1), with 15 mice in each group. The UC model was induced in mice by freely drinking a 3% DSS solution for 7 days. After 12 hours of modeling, the treatment groups received daily oral administration, while the other groups received an equal volume of normal saline by gavage. Daily body weight and disease activity index (DAI) were recorded. On the 8th day, mice were euthanized after anesthesia, and the colon and feces were collected. The colon length was measured, and histopathological changes were observed after hematoxylin-eosin (HE) staining. Tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-18 (IL-18) levels in the colon were detected by enzyme-linked immunosorbent assay (ELISA). The differences in gut microbiota among the groups were analyzed using 16S rRNA sequencing technology. The protein content of NLRP3/Caspase-1/GSDMD in colon tissues was detected by Western blot. ResultCompared with the blank group, mice in the model group showed increased DAI (P<0.01), shortened colon length (P<0.01), severe colon mucosal damage, elevated levels of TNF-α, IL-1β, and IL-18 (P<0.01), increased protein content of NLRP3/Caspase-1/GSDMD in colon tissues (P<0.01), altered gut microbiota structure with decreased abundance of Actinobacteria, Bacteroidetes, and Proteobacteria, and increased abundance of Firmicutes at the phylum level. At the genus level, there was a decrease in Lactobacillus, Alloprevotella, and Yersinia, and an increase in Bacteroides, Bacillus, and Lachnospiraceae_NK4A136. Compared with the model group, the MKNF group and the mesalazine group showed a significant reduction in DAI after the 3rd day (P<0.01), a significant increase in colon length (P<0.01), alleviated colon inflammation and mucosal structural damage, and decreased TNF-α, IL-1β, and IL-18 levels in the colon (P<0.01), reduced protein content of NLRP3/caspase-1/GSDMD in colon tissue (P<0.05, P<0.01),an increase in the abundance of Proteobacteria and Bacteroidetes, and a decrease in Firmicutes at the phylum level. ConclusionMKNF can alleviate UC-induced colonic inflammation, reduce colon damage, and improve dysbiosis of the gut microbiota by inhibiting the classical pyroptosis pathway.
