ABSTRACT

We reported an 8-year-old boy with panscleritis in left eye and right epididymitis after falling on the ground. Etiologic diagnosis played a key role in this case. Systemic examinations ruled out systemic autoimmune diseases, tumors, and infections as the cause of scleritis and suggested that the disease was caused by a local delayed-type hypersensitivity (DTH) induced by ocular trauma and was non-infectious. Still, the right epididymitis was infectious. Both conditions were treated successfully using steroids and antibiotics, respectively. Thus, early etiologic diagnosis and reasonable treatment are crucial to prevent visual loss.

ABSTRACT

Objective: To investigate the spontaneous nystagmus (SN) and the frequency characteristics of affected semicircular canals in patients with vestibular neuritis (VN). Methods: This is a cross-sectional study. A total of 61 patients with VN admitted to the Department of Neurology of Shanxi Bethune Hospital from June 2020 to October 2021, 39 were male and 22 were female, with a mean age of (46±13) years old and male to female ratio of 1.77∶1. According to SN characteristics, 61 patients were divided into non-nystagmus group(nSN), horizontal nystagmus group(hSN) and horizontal-torsional nystagmus group (htSN). Clinical data were collected, and SN, unilateral weakness (UW), directional preponderance (DP), and video head impulse test (vHIT) gain were used as observation indicators. Statistical analysis by SPSS23.0 software. Normal distributed quantitative data (age, semicircular canal gain, SN intensity) were expressed by x¯±s, non-normal distributed quantitative data (disease course, UW, DP) were expressed by M(Q1,Q3), qualitative data were expressed by rate and composition ratio, difference analysis by one-way ANOVA, rank sum test, Chi-square test or Fisher's exact probability method, considered by P value<0.05. Results: (1)The disease course of nSN, hSN and htSN was 7.0 (4.0, 12.5), 6.0 (3.5, 11.5), and 3.0 (2.0, 6.5) days respectively, and there were statistical differences (χ2=7.31,P=0.026).(2)The horizontal nystagmus intensity of htSN was (16.8±8.6)°/s, which was significantly higher than that of (9.8±4.7)°/s in hSN (t=3.71, P<0.001). There was no significant difference in the positive rate of UW between the three groups (P=0.690), and there was a significant difference in the positive rate of DP in the three groups (χ2=12.23, P=0.002). The horizontal nystagmor intensity in the htSN was positively correlated with the vertical nystagmus intensity (r=0.59, P=0.001).(3)The gain of the affected horizontal canal of the three groups was statistically different (F=8.28, P=0.001), and the gain of the horizontal canal of hSN and htSN was significantly lower than that of nSN (t=2.74, P=0.008; t=4.05, P<0.001); The gain of the affected anterior canal in the three groups was statistically different (F=5.32, P=0.008). The gain of the anterior canal in both nSN and hSN was significantly higher than that in htSN (t=3.09, P=0.003; t=2.15, P=0.036). The horizontal canal gain of htSN is positively correlated with the anterior canal gain (r=0.74, P<0.001).(4)The affected semicircular canals in the two groups with no-vertical-component nystagmus (nSN and hSN) and the htSN were counted. The composition ratio of the affected semicircular canals in the two groups was different (χ2=8.34, P=0.015). Conclusion: The occurrence of SN in patients with VN is related to many factors, such as the disease course, low and high frequencies, and the severity of the condition in the affected semicircular canal.

ABSTRACT

Objective:To explore the pathological differences of surgically resected specimens of advanced esophageal squamous cell carcinoma (ESCC) to different neoadjuvant therapies (neoadjuvant radiochemotherapy and toripalimab combined with neoadjuvant radiochemotherapy).Methods:Thirty patients diagnosed with advanced ESCC who underwent surgical operation after neoadjuvant therapy in Jiangsu Cancer Hospital from October 2020 to September 2021 were included. Among them, 15 patients received neoadjuvant radiochemotherapy (radiochemotherapy group) and 15 patients were treated with toripalimab combined with radiochemotherapy (immunotherapy combined with radiochemotherapy group). Surgically resected specimens were collected. The histopathological features of primary esophageal lesions and the responses of involved lymph nodes were analyzed and compared between two groups.Results:The major pathological response (MPR) rate in the radiochemotherapy group was 10/15, and 14/15 in the immunotherapy combined with radiochemotherapy group ( P=0.17). The pathological complete response (pCR) rate of the primary lesions in the radiochemotherapy group was 7/15, and 10/15 in the immunotherapy combined with radiochemotherapy group ( P=0.46). In the radiochemotherapy group, the incidence rate of tertiary lymphoid structure (TLS) was 7/15, and 12/15 in the immunotherapy combined with radiochemotherapy group ( P=0.02). The incidence rate of necrosis in the radiochemotherapy group was 6/15, and 1/15 in the immunotherapy combined with radiochemotherapy group ( P=0.03). In addition, the incidence rate of foam cell infiltration in the radiochemotherapy group was 6/15, and 13/15 in the immunotherapy combined with radiochemotherapy group ( P=0.01). Furthermore, the pCR rate of involved lymph nodes in the radiochemotherapy group was 7/33, and 11/12 in the immunotherapy combined with radiochemotherapy group ( P<0.001). Conclusion:Compared with the radiochemotherapy group, the incidence of TLS and foam cell infiltration is higher, the incidence of necrosis is lower and clinical efficacy of involved lymph nodes is higher in the immunotherapy combined with radiochemotherapy group, prompting that toripalimab combined with neoadjuvant radiochemotherapy exert higher synergistic immune effect.

ABSTRACT

This study aimed to explore the infrared manifestation and role of brown adipose tissue(BAT) in phlegm-dampness me-tabolic syndrome(MS), and to provide objective basis for clinical diagnosis and treatment of phlegm-dampness MS. Subjects were selected from the department of endocrinology and ward in the South District of Guang'anmen Hospital, China Academy of Chinese Medical Sciences from August 2021 to April 2022, including 20 in healthy control group, 40 in non phlegm-dampness MS group and 40 in phlegm-dampness MS group. General information, height and weight of the subjects were collected and body mass index(BMI) was calculated. Waist circumference(WC), systolic blood pressure(SBP) and diastolic blood pressure(DBP) was measured. Triglyceride(TG), high density lipoprotein cholesterol(HDL-C), fasting blood glucose(FBG), fasting insulin(FINS), leptin(LP), adiponectin(ADP) and fibroblast growth factor-21(FGF-21) were detected. The infrared thermal image of the supraclavicular region(SCR) of the subjects before and after cold stimulation test was collected by infrared thermal imager and the changes of infrared thermal image in the three groups were observed. In addition, the differences in the average body surface temperature of SCR among the three groups were compared, and the changes of BAT in SCR were analyzed. The results showed compared with the conditions in healthy control group, the levels of WC, SBP, DBP, TG and FPG in MS groups were increased(P<0.01), and the HDL-C level was decreased(P<0.01). Compared with non phlegm-dampness MS group, phlegm-dampness MS group had higher conversion score of phlegm dampness physique(P<0.01). According to the infrared heat map, there was no difference in the average body surface temperature of SCR among the three groups before cold stimulation. while after cold stimulation, the average body surface temperature of SCR in MS groups was lower than that in healthy control group(P<0.05). After cold stimulation, the maximum temperature of SCR and its arrival time in the three groups were as follows: healthy control group(3 min)>non phlegm-dampness MS group(4 min)>phlegm-dampness MS group(5 min). The thermal deviation of SCR was increased and the average body surface temperature of left and right sides were higher(P<0.01) in healthy control group and non phlegm-dampness MS group, while the thermal deviation of SCR did not change significantly in the phlegm-dampness MS group. Compared with that in healthy control group, the elevated temperature between left and right sides was lower(P<0.01, P<0.05), and compared with that in non phlegm-dampness MS group, the elevated temperature of left side was lower(P<0.05). The changes of the average body surface temperature of SCR in the three groups were in the order of healthy control group>non phlegm-dampness MS group>phlegm-dampness MS group. Compared with the conditions in healthy control group and non phlegm-dampness MS group, FINS, BMI and FGF-21 levels were increased(P<0.01,P<0.05), while ADP level was decreased(P<0.01, P<0.05) in phlegm-dampness MS group. Moreover, the LP level in phlegm-dampness MS group was higher than that in non phlegm-dampness MS group(P<0.01). It was observed in clinical trials that after cold stimulation, the average body surface temperature of SCR in MS patients was lower than that of the healthy people; the thermal deviation of SCR did not change significantly in the phlegm-dampness MS patients, and the difference in their elevated temperature was lower than that in the other two groups. These characteristics provided objective basis for clinical diagnosis and treatment of phlegm-dampness MS. With abnormal BAT related indicators, it was inferred that the content or activity of BAT in SCR of phlegm-dampness MS patients were reduced. There was a high correlation between BAT and phlegm-dampness MS, and thus BAT might become an important potential target for the intervention in phlegm-dampness MS.

ABSTRACT

Aim This study aimed to assess the therapeutic potential of ACT001, a micheliolide derivative, in the treatment of acute lung injury ( ALI) induced by sepsis and investigate its pharmacological mechanisms. Methods At the animal level, an ALI model was established in mice through intraperitoneal injection of li-popolysaccharide (LPS). Subsequently, ACT001 was administered to the ALI-afflicted mice. The therapeutic effects of ACT001 were assessed by evaluating factors such as individual survival rate, lung inflammation, and pulmonary edema. At the cellular level, RAW264. 7 cells were stimulated with LPS to explore the pharmacological mechanism of ACT001. The study examined inflammatory response and oxidative stress levels, and proteomics analysis was conducted to investigate the underlying molecular mechanisms. Results At the animal level, ACT001 can improve the survival of mice with ALI, reduce lung inflammation, and reduce the levels of inflammatory cytokines in serum. At the cellular level, ACT001 promotes the polarization of RAW264. 7 cells toward an anti-inflammatory pheno-type by inhibiting MHC-II related pathways, inhibiting the production of NO and related inflammatory cytokines while increasing SOD content and scavenging ROS. Conclusions ACT001 exhibited the potential to alleviate ALI via its anti-inflammatory and antioxidative activity, mainly by inhibiting the STAT1/ CIITA/ MHC-II pathway. ACT001 holds promise as a novel therapeutic candidate for the treatment of ALI induced by sepsis.

ABSTRACT

The present study was aimed to investigate whether Gasdermin D (GSDMD)-mediated pyroptosis participated in lipopolysaccharide (LPS)-induced sepsis-associated acute kidney injury (AKI), and to explore the role of caspase-1 and caspase-11 pyroptosis pathways in this process. The mice were divided into four groups: wild type (WT), WT-LPS, GSDMD knockout (KO) and KO-LPS. The sepsis-associated AKI was induced by intraperitoneal injection of LPS (40 mg/kg). Blood samples were taken to determine the concentration of creatinine and urea nitrogen. The pathological changes of renal tissue were observed via HE staining. Western blot was used to investigate the expression of pyroptosis-associated proteins. The results showed that the concentrations of serum creatinine and urea nitrogen in the WT-LPS group were significantly increased, compared with those in the WT group (P < 0.01); whereas serum creatinine and urea nitrogen in the KO-LPS group were significantly decreased, compared with those in the WT-LPS group (P < 0.01). HE staining results showed that LPS-induced renal tubular dilatation was mitigated in GSDMD KO mice. Western blot results showed that LPS up-regulated the protein expression levels of interleukin-1β (IL-1β), GSDMD and GSDMD-N in WT mice. GSDMD KO significantly down-regulated the protein levels of IL-1β, caspase-11, pro-caspase-1, caspase-1(p22) induced by LPS. These results suggest that GSDMD-mediated pyroptosis is involved in LPS-induced sepsis-associated AKI. Caspase-1 and caspase-11 may be involved in GSDMD cleavage.

ABSTRACT

OBJECTIVE@#To explore the incidence and risk factors of readmission of elderly patients with hip fracture after hip hemiarthroplasty.@*METHODS@#A retrospective analysis of 237 elderly hip fracture patients who underwent hip hemiarthroplasty from February 2015 to October 2020 were performed. According to the readmission status of the patients at 3 months postoperatively, the patients were divided into readmission group (39 cases)and non-readmission group(198 cases). In readmission group, there were 7 males and 32 females with an average age of(84.59±4.34) years old, respectively, there were 34 males and 164 females with average age of (84.65±4.17) years old in non-readmission group. The general information, surgical status, hip Harris score and complications of patients in two groups were included in univariate analysis, and multivariate Logistic regression was used to analyze independent risk factors of patients' readmission.@*RESULTS@#The proportion of complications(cerebral infarction and coronary heart disease) in readmission group was significantly higher than that of non-readmission group (P<0.05), and intraoperative blood loss in readmission group was significantly higher than that of non-readmission group(P<0.05). Harris score of hip joint was significantly lower than that of non-readmission group(P<0.05). The proportion of infection, delirium, joint dislocation, anemia and venous thrombosis in readmission group were significantly higher than that of non-readmission group (all P<0.05). Multivariate Logistic regression analysis showed that the risk factors for readmission of elderly patients with hip fracture after hip hemiarthroplasty included cerebral infarction, infection, delirium, dislocation, anemia and venous thrombosis (all P<0.05).@*CONCLUSION@#The complications of the elderly patients who were readmission after hip hemiarthroplasty for hip fractures were significantly higher than those who were non-readmission. Cerebral infarction, infection, delirium, dislocation, anemia and venous thrombosis are risk factors that lead to patient readmission. Corresponding intervention measures can be taken clinically based on these risk factors to reduce the incidence of patient readmissions.

ABSTRACT

OBJECTIVE@#To investigate whether blood-brain barrier (BBB) served a key role in the edema-relief effect of bloodletting puncture at hand twelve Jing-well points (HTWP) in traumatic brain injury (TBI) and the potential molecular signaling pathways.@*METHODS@#Adult male Sprague-Dawley rats were assigned to the sham-operated (sham), TBI, and bloodletting puncture (bloodletting) groups (n=24 per group) using a randomized number table. The TBI model rats were induced by cortical contusion and then bloodletting puncture were performed at HTWP twice a day for 2 days. The neurological function and cerebral edema were evaluated by modified neurological severity score (mNSS), cerebral water content, magnetic resonance imaging and hematoxylin and eosin staining. Cerebral blood flow was measured by laser speckles. The protein levels of aquaporin 4 (AQP4), matrix metalloproteinases 9 (MMP9) and mitogen-activated protein kinase pathway (MAPK) signaling were detected by immunofluorescence staining and Western blot.@*RESULTS@#Compared with TBI group, bloodletting puncture improved neurological function at 24 and 48 h, alleviated cerebral edema at 48 h, and reduced the permeability of BBB induced by TBI (all P<0.05). The AQP4 and MMP9 which would disrupt the integrity of BBB were downregulated by bloodletting puncture (P<0.05 or P<0.01). In addition, the extracellular signal-regulated kinase (ERK) and p38 signaling pathways were inhibited by bloodletting puncture (P<0.05).@*CONCLUSIONS@#Bloodletting puncture at HTWP might play a significant role in protecting BBB through regulating the expressions of MMP9 and AQP4 as well as corresponding regulatory upstream ERK and p38 signaling pathways. Therefore, bloodletting puncture at HTWP may be a promising therapeutic strategy for TBI-induced cerebral edema.

Due to its own internal laws of development, Chinese medicine (CM) seems more inclined to empirical medicine in a relatively long historical period. It is considered to be lacking objective and unified clinical practice guidelines (CPGs), and the difficulties in diagnosis and therapeutic effect evaluation comes with it, have restricted its further inheritance, development and international communication. Over the years, our research group has been committed to improving the standardization theory and methodology of CM, also perfecting relative techniques for further application, which are all based on the stratified evidence scoring method. We have already applied this method to 45 issued guidelines, including 5 national guidelines, 3 industrial guidelines, and 37 formulation/revision social organization guidelines. The stratified evidence scoring method has been recognized and used widely. It helps scholars and applicators to study, formulate, publish and popularize the acupuncture therapy clinical practice guidelines better, thus further promotes the development of acupuncture therapy.

ABSTRACT

Objective:To compare the effect of stripped perforator pedicle on the survival of perforator flap.Methods:From January, 2015 to December, 2019, 44 patients with soft tissue defects of distal shank and ankle were repaired with perforating vessel pedicled propeller flap. According to the nudity of the perforator pedicle, the patients were divided into 2 groups: stripped group ( n=14) and non-stripped group ( n=30). The gender, age, history of smoking, history of diabetes, location of wound, size of flap, perforator artery of flap, closure method of donor site, degree of flap swelling 3 days after operation, percentage of survival area of flap 7 days after operation and postoperative complications were analysed retrospectively. Data were analyzed statistically. The difference was statistically significant when P<0.05. Results:There was no significant difference between the 2 groups in age, smoking history, diabetes history, wound location, size of flap, perforator artery and donor site closure( P<0.05). The degree of swelling of flap in the stripped group 3 days after operation [(+) 94.00%, (++) 6.00%, (+++) 0.00%, (++++) 0.00%)] was less than that in the non-stripped group [(+)47.00%, (++) 29.00%, (+++) 13.00%, (++++) 11.00%)] . The difference was statistically significant between the 2 groups( P<0.05). The percentage of flap survival area in the stripped group [(100.00±0.00) %] was higher than that in the non-stripped group [(88.23±21.29)%] , and the difference was statistically significant ( P<0.05). The incidence of postoperative complications in the stripped group(0.00%) was lower than that in the non-stripped group (39.00%). The difference heel statistically significant( P<0.05). Conclusion:The stripped pedicle of the perforating vessel can promote a better survival of the arterial perforating branch propeller flap, and the degree of postoperative swelling and complications of the flap are lower.

ABSTRACT

OBJECTIVE@#To identify the prominent molecular signaling in acupoints and explore their roles in initiating the analgesia effect of manual acupuncture (MA).@*METHOD@#A three-step study was conducted, the experiment 1 was a genome-wide analysis of the tissue at acupoint Zusanli (ST 36), including 12 Wistar rats which were divided into control, control+MA1, and control+MA7 groups. In the experiment 2, the paw withdrawal latency (PWL), immunohistochemistry and Western blot analysis of phospho-nuclear factor kappa B (NFκB) p65 (p-p65), phospho-NFκB p50 (p-p50) at ST 36 were performed on rats of saline, saline+MA, and complete Freund's adjuvant (CFA)+MA groups (n=6). In experiment 3, 24 rats were divided into saline+DMSO, CFA+DMSO, CFA+DMSO+MA, and CFA+BAY 11-7082+MA groups, the PWL and immunofluorescence assay of NFκB p65 at ST 36 was conducted.@*RESULT@#(1) The gene: inhibitor of NFκB (Nfkbia), interleukin-1β (Il1b), interleukin-6 (Il6), chemokine c-x-c motif ligand 1 (Cxcl1), monocyte chemoattractant protein-1 (MCP-1/Ccl2) expressions in the control+MA7 group were significantly increased (P<0.05 or P<0.01), and the expression of NFκB p65 (Rela), NFκB p50 (Nfkb1) were increased in the control+MA7 group (P<0.05). (2) CFA+MA groups showed increased PWL from day 1 to 7 (P<0.01 vs. CFA), and the Western blot results were consistent with immunohistochemistry, the expression of NFκB p-p65 and NFκB p-p50 were significantly increased in the MA-related groups compared with control and CFA groups (P<0.05). (3) Compared with the CFA+DMSO+MA group, the PWL of the CFA+ BAY 11-7082+MA group decreased significantly and continued until day 5 and 7 (P<0.05 and P<0.01, respectively), and the NFκB p65 expression of CFA+BAY 11-7082+MA was significantly reduced compared with CFA+DMSO+MA (P<0.01).@*CONCLUSION@#Local NFκB signaling cascade in acupoint caused by MA is an important step in initiating the analgesic effect, which would provide new evidence for the initiation of MA-effect and improve the understanding of the scientific basis of acupuncture analgesia.

ABSTRACT

OBJECTIVE@#To evaluate the effect of one-stage treatment of bone morphogenetic protein 2 combined with Jifusheng in the experimental model of osteomyelitis in rabbits.@*METHODS@#The model of chronic osteomyelitis of tibia was established in 30 3-month-old male New Zealand white rabbits with a body weight of (2.0±0.5) kg, and the model was verified 4 weeks after operation. Thirty rabbits with osteomyelitis were randomly divided into 3 groups with 10 rabbits in each group (@*RESULTS@#At 4 weeks after operation, 30 rabbits with osteomyelitis were successfully validated. The results of serological examination showed that the hypersensitive C-reactive protein (CRP) and white blood cell count(WBC)in the model group were significantly higher than those in the blank group at 2 and 4 weeks after operation. Eight weeks after treatment, the detection of blood indexes showed that the white blood cell count (WBC)and hypersensitive C reactive protein (CRP)in treatment group A and treatment group B were significantly lower than those in the model group (@*CONCLUSION@#The combined application of apolipoprotein 2-Jifusheng can promote bone repair and reduce the inflammation of the focus. it can treat rabbits with osteomyelitis in one stage, provide objective basis for the formulation of clinical treatment strategy of osteomyelitis and further promote clinical research.

ABSTRACT

Microarray data of hippocampal tissue(HC) of the cognitively intact elderly(60-99 years old) were compared with those of the middle-aged and the young(20-59 years old) by bioinformatics techniques to initially screen out differentially expressed genes(DEGs) and then predict potential effective Chinese medicinals for the treatment of brain aging. The gene expression profile(accession: GSE11882) was downloaded from the Gene Expression Omnibus(GEO) and DEGs were screened based on R package. The key DEGs were identified by STRING, Cytoscape and the plug-in, followed by Gene Ontology(GO) term and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway analysis. Then the key genes and the medical ontology information retrieval platform(Coremine Medical) were mapped against each other to single out the Chinese medicinals for the treatment of brain aging and construct the " Chinese medicinal-active constituent-target" network. Among the resultant 268 DEGs(246 down-regulated and 22 up-regulated), the 15 key genes were mainly involved in biological processes such as leukocyte migration, neutrophil activation, cell chemotaxis, microglia activation and response to external stimulus, and pathways such as inflammatory process, immune response, cytokine-cytokine receptor interaction, PI3 K-Akt signaling pathway, Rap1 signaling pathway, chemokine signaling pathway and Toll-like receptor signaling pathway. The potential effective Chinese medicinals were Notoginseng Radix et Rhizoma, Ginseng Radix et Rhizoma, Salviae Miltiorrhizae Radix et Rhizoma and Astragali Radix. The analysis of DEGs and key genes enhances the understanding of the mechanisms of brain aging. This study provides potential gene targets and ideas for the development of Chinese medicine for brain aging.
