Objective Exploring the mechanism of"Wushen acupuncture"in alleviating chronic fatigue in rats from the perspective of mitophagy.Methods Forty male Wistar rats were randomly allocated into a normal group and a modeling group,where the latter employed a protocol combining exhaustive swimming with tail-clamping stimuli to induce a rat model of chronic fatigue.Post-modeling,the normal group was subdivided randomly into a blank group and a presumed control group with specifics requiring clarification.Meanwhile,the modeling group was further randomized into a model group,a"Wushen acupuncture"group that underwent acupuncture at the Baihui and Sishencong points,and a non-acupoint control group,in which acupuncture was applied to 5 mm behind houshencong which is non-meridian,non-acupoint sites on the rats' heads and necks.The modeling and treatment outcomes in rats are assessed via the tail suspension test.Protein relative expression levels of adenosine 5'-monophosphate-activated protein kinase(AMPK),mammalian target of rapamycin(mTOR),and peroxisome proliferator-activated receptor γ coactivator 1-alpha(PGC-1α)in rat skeletal muscle were detected using Western blot.Meanwhile,the relative mRNA expression levels of PTEN induced putative kinase 1(PINK1)and Parkin were measured by Real-Time PCR.Results In contrast to the baseline cohort,rats in the induced fatigue model displayed a reduction in struggles,struggle duration,swaying frequency,and swaying duration(P<0.05).When juxtaposed against the fatigue-induced model group,the"Wushen acupuncture"intervention cohort manifested a substantial increase in these behavioral parameters(P<0.05).Furthermore,relative to the"Wushen acupuncture"intervention group,the non-acupoint control cohort showed a decrease in struggles,struggle duration,swaying frequency,and swaying duration(P<0.05).Versus the baseline group,the fatigue-induced model cohort demonstrated a marked decrease in the relative expression levels of AMPK,PGC-1α,PINK1,and Parkin mRNA in skeletal muscle tissue(P<0.05),alongside an increase in mTOR protein expression(P<0.05).Compared to the fatigue-induced model group,the"Wushen acupuncture"intervention led to an increase in the relative expression levels of AMPK,PGC-1α,PINK1,and Parkin mRNA(P<0.05),and a decrease in mTOR protein expression(P<0.05).When juxtaposed against the"Wushen acupuncture"intervention group,the non-acupoint control cohort showed decreased relative expression levels of AMPK,PGC-1α,PINK1,and Parkin mRNA(P<0.05),and increased mTOR protein expression(P<0.05).Conclusion The"Wushen acupuncture"have been shown to enhance the alleviation of chronic fatigue symptoms in rat models and modulate the functionality of mitochondrial autophagy.This therapeutic effect is believed to be mechanistically linked to the regulation of both the PINK1/Parkin pathway and the AMPK/mTOR signaling cascade.

This study was to investigate the relationship between spring pollen distribution concentration, species and the detection results of air-borne pollen allergens in Taiyuan City, Shanxi Province during March to May 2022 and March to May 2023.A retrospective study was conducted in the Otorhinolaryngology Head and Neck Surgery Clinic of the First Hospital of Shanxi Medical University.Pollen particles will be monitored by gravity sedimentation method on the roof of the outpatient department of the First Hospital of Shanxi Medical University in downtown Taiyuan from March to May 2022-2023, and pollen species and quantity will be observed and recorded under an optical microscope.The air-borne pollen allergen detection results of all allergic rhinitis patients in the otolaryngology Head and Neck surgery Department of the First Hospital of Shanxi Medical University were extracted from the relevant outpatient system. SPSS software and Pearson correlation analysis were used to compare the correlation between the allergens and the dominant air-borne pollen monitoring results. Results are as follows: (1)A total of 18 species of spring pollen in Taiyuan City were monitored in 2022-2023, with 101 177.5 grains, and the dominant airborne pollen was poplar (16.69%) and pine (29.06%) pollen. The pollen of poplar (11.96%), elm (7.89%) and cypress (8.68%) were dominant in early spring; Pine (25.16%) pollen predominated in late spring. The two peaks of pollen dispersal in Taiyuan were in late March (15 479 grains) and early and mid May (15 094/15 343 grains).(2) The positive rates of allergens in serum specific IgE detection were: wormwood (46%, 248/541 cases), tree combination (26%, 143/541 cases), ragweed (19%, 101/541 cases), humulus scandens (9%, 49/541 cases).(3)There was a linear positive correlation between the positive rate of air-borne pollen allergens in allergic rhinitis patients in the Department of Otolaryngology Head and Neck Surgery in the First Hospital of Shanxi Medical University and the dominant air-borne pollen concentration in the same period ( P<0.05, r=0.999). In conclusion, two spring pollen dispersal peaks were formed in late March and early to mid May in Taiyuan City, and the dominant air-borne pollens were poplar and pine pollens. The positive rate of air borne pollen allergen sIgE showed that wormwood allergy was the highest.There was a positive correlation between the concentration of air-borne pollen and the positive rate of air-borne pollen allergens in patients with allergic rhinitis in the Department of otorhinolaryngology and head and neck surgery in Taiyuan in 2022 and 2023.The monitoring of pollen distribution in spring can provide an important scientific basis for clinical workers to formulate prevention and treatment plans for patients with allergic rhinitis in the season, and provide data reference for the epidemiological investigation of allergic diseases in Taiyuan in the future.

Objective:To study the relationships between host immune function in the tumor microenvironment (TME) and early-stage lung cancer progression. Methods:A total of 216 patients with early-stage lung cancer admitted to Zhumadian Central Hospital between Febru-ary 2020 and April 2023 were included to analyze immune cell presence in cancer and adjacent tissues. The patients were assigned into a re-lapse group (41 cases) and a non-recurrence group (175 cases) based on their relapse status. Baseline data and immune cell expression in the two groups were compared to analyze the influence and predictive value of immune cell prevalence on lung cancer recurrence. Results:The proportion of CD56+natural killer (NK) cells was lower in cancer tissues than that in adjacent tissues. The infiltration rates of CD68+tu-mor-associated macrophages (TAMs) and CD163+TAMs,as well as the proportions of CD4+and CD8+T cells,were higher in adjacent tissues than in cancerous tissues (P<0.05). In the recurrence group,the maximum tumor diameter,proportion of patients with micro-papillary struc-tures,CD68+TAM and CD163+TAM infiltration rates,and CD8+T cell proportion were higher than those in the non-recurrent group,while the CD56+NK cell positive rate was lower (P<0.05). After correction,CD56+NK positivity,elevated CD68+TAM and CD163+TAM infiltration,and CD8+T cell proportion were independent factors associated with early-stage lung cancer recurrence (P<0.05). The AUC for predicting early-stage lung cancer recurrence using CD56+NK positivity+high CD68+TAM and CD163+TAM infiltration+proportion of CD8+T cells was 0.949,which was higher than that of each individual immune marker (P<0.05). Conclusions:Host immune function in the TME in patients with early lung cancer correlates with disease progression. The combination of high CD56+NK+,CD68+TAM infiltration,high CD163+TAM infiltration,and CD8+T-cell ratio can improve prediction efficiency for early lung cancer recurrence.

Robot-assisted fracture reduction usually involves fixing the proximal end of the fracture and driving the distal end of the fracture to the proximal end in a planned reduction path. In order to improve the accuracy and safety of reduction surgery, it is necessary to know the changing rule of muscle force and reduction force during reduction. Fracture reduction force was analyzed based on the muscle force of femoral. In this paper, a femoral skeletal muscle model named as PA-MTM was presented based on the four elements of skeletal muscle model. With this, pinnate angle of the skeletal muscle was considered, which had an effect on muscle force properties. Here, the muscle force of skeletal muscles in different muscle models was compared and analyzed. The muscle force and the change of the reduction force under different reduction paths were compared and simulated. The results showed that the greater the pinnate angle was, the greater the influence of muscle strength was. The biceps femoris short head played a major role in the femoral fracture reduction; the force in the

Objective:To investigate the relationship between plasma Golgi protein 73 (GP73) levels and the occurrence and development of non-alcoholic fatty liver disease (NAFLD), and to establish a diagnostic model based on this combination with lipid metabolism indicators to clarify its diagnostic efficacy and clinical application value for NAFLD.Methods:225 cases with NAFLD [diagnosed by ultrasound, transient elastography (FibroScan502) and liver biopsy (some patients)] and 108 healthy controls were selected from the Department of Hepatology and Physical Examination Center of Integrated Traditional Chinese and Western Medicine, The Third Hospital of Hebei Medical University. Clinical data, routine peripheral blood and serum biochemical test results were collected. The plasma GP73 level was detected by enzyme-linked immunosorbent assay. SPSS 21.0 statistical software was used for statistical analysis. Binary logistic regression model was used to calculate the NAFLD diagnostic model. Receiver operating characteristic curve was used to evaluate the NAFLD constructed model diagnostic efficacy.Results:NAFLD incidence was significantly reduced in younger age group, mostly in young and middle-aged male. However, the NAFLD incidence was increased with increasing age in female. The analysis of age ratio composition showed that the average age for NAFLD onset was 20 ~ 50 years old, and the incidence rate was as high as 47% in among 30 ~ 39 years old, but the incidence rate was significantly decreased in over 60 years old (4.00%). GP73 was an independent risk factor for the occurrence and development of NAFLD. The diagnostic models of GBT, GB and GT were established by GP73 (G) combined with body mass index (BMI, B) and serum triglyceride (TG, T), and the results showed that the areas under the curves of GBT, GB and GT models were 0.969, 0.937 and 0.909, respectively. The sensitivity and the specificity were 84.90%, 77.80% and 84.00%, and 95.40%, 95.40% and 82.40%, respectively, P < 0.05. The GBT model had efficacy of best diagnostic performance. Conclusion:NAFLD is more common in young and middle-aged male, but with advanced age, the incidence of female patients gradually increases. Plasma GP73 levels are related to the occurrence and development of NAFLD. The GBT model can be used as a new model for non-invasive diagnosis and one of the indicators for clinical evaluation of diagnostic efficacy of NAFLD.

Objective: To explore the clinical value of plasma heme oxygenase 1(HO-1) in the development of non-alcoholic fatty liver disease(NAFLD). Methods: Patients with NAFLD were selected from the Physical examination center and the Department of Traditional and Western Medical Hepatology of Third Hospital of Hebei Medical University. A combination of ultrasound and liver elastography was used to screen NAFLD patients and healthy persons. General clinical characteristics, peripheral blood cell count and liver biochemical test results were collected synchronously, plasma samples were retained, and plasma HO-1 level was detected by enzyme-linked immunosorbent assay. SPSS21.0 statistical software was used for statistical analysis, multivariate logistic regression analyses was used to analyse the independent risk factors affecting the incidence and progression of NAFLD. The diagnostic efficacy of indicators related to development of NAFLD was assessed by the receiver operating characteristic curve(ROC). Results: A total of 328 patients with NAFLD and 113 healthy controls were included. According to the liver biochemical results, the NAFLD group was divided into 148 patients with normal liver enzymes and 180 patients with abnormal liver enzymes. The level of HO-1 in the three groups was 9.09 ± 2.19, 14.38 ± 2.63, 17.00 ± 3.30 ng/ml, and was increased respectively of healthy controls, patients with normal liver enzymes and patients with abnormal liver enzymes. Analyzing plasma HO-1 levels of components associated with metabolic disorders suggests that components without metabolic syndrome(9.83 ± 3.21) < components with 1 metabolic syndrome(13.59 ± 3.72) < components with 2 or more metabolic syndrome(16.09 ± 3.41), P < 0.001. The results of HO-1 level stratification analysis showed that WBC, ALT, AST, GGT, TG increased as HO-1 level increased, and the pairwise difference was statistically significant (P < 0.001). The WBC count of NAFLD is significantly higher than healthy group(6.79 ± 1.62 vs 5.68 ± 1.36, P < 0.001). The univariate and multivariate regression analyses of all the subjects showed that HO-1, TG and BMI were prognostic factors for the occurrence of NAFLD and HO-1, TC, GLU were prognostic factors for the progression of NAFLD, P < 0.05. The ROC analysis showed that HO-1 was reliable markers for predicting the occurrence and progression of NALFD, the sensitivity and specificity were respectively 85.10%, 92.90% and 38.33%, 95.27%. Conclusion Plasma HO-1 can predict the occurrence and progression of NAFLD and is expected to be a novel molecular diagnostic marker for NAFLD and NASH.
