ABSTRACT
Objective To investigate the effect of diosmine on semen quality and sex hormone concentra-tion in patients with spermatovenous ligation.Methods Clinical data were retrospectively collected from January 2019 to January 2022 on patients with varicocele admitted to Department of Urology,General Hospital of Southern Theater Command,divided into a control group and a study group based on whether they had a history of Diosmine use after surgery.Clinical data from both groups were matched using propensity score matching.Sperm quality and sex hormone tests were then compared before surgery,three months after surgery and six months after surgery.Results There were 73 in the control group and 73 in the study group.Both groups were balanced in terms of age,BMI,seminal fluid volume and testosterone(P＞0.05).Sperm motility,forward motility and testosterone were all increased 3 and 6 months after surgery,and sperm malformations,sperm DNA fragment index,follicle stimulating hormone and luteinizing hormone were all reduced significantly(P＜0.05).The results were also better than those in the control group for total sperm motility,forward motility,testosterone,sperm DNA fragment index,follicle stimulating hormone and luteinizing hormone(P＜0.05).Conclusions Diosmine can help to restore semen quality and improve sex hormone concentration in patients with varicocele after Laparoscopic varicocelectomy.
ABSTRACT
BACKGROUND:Pretreatment with moxibustion is a preventive treatment in traditional Chinese medicine.Pretreatment with moxibustion at the onset of prodromal symptoms can significantly reduce the symptoms and delay the onset of many diseases,but the exact mechanism remains to be studied. OBJECTIVE:To investigate the mechanism of SIRT1/FoxO3 pathway in moxibustion pretreatment to ameliorate oxidative stress injury in cerebral ischemia-reperfusion model rats. METHODS:Forty-eight Sprague-Dawley rats were randomly divided into sham-operated group,model group,moxibustion pretreatment group,and moxibustion pretreatment+EX527(SIRT1 inhibitor)group,with 12 rats in each group.The moxibustion pretreatment group was given moxibustion with seed-sized moxa cone at Baihui,Dazhui,and Zusanli before modeling,three moxa-cones per acupoint,once a day for 7 days.In the model group,moxibustion pretreatment group and moxibustion pretreatment+EX527 group,the rat model of middle cerebral artery occlusion was made by suturing of the middle cerebral artery 30 minutes after the last moxibustion.After 2 hours of cerebral ischemia,the middle artery suture was removed and the rats were reperfused for 12 hours.In the sham-operated group,only the common carotid artery,internal carotid artery,and external carotid artery were dissected without suturing the middle cerebral artery.In the moxibustion pretreatment+EX527 group,EX527(15 mg/kg)was given intraperitoneally 30 minutes before each moxibustion.After 12 hours of reperfusion,the rats were scored for neurological deficits,and the cerebral infarct volume was calculated by 2,3,5-triphenyltetrazolium chloride staining method.The levels of oxidative stress factors in the infarcted tissues were detected by the kit method,and western-blot method was used to detect the expression levels of SIRT1,FoxO3,p-FoxO3 and brain-derived neurotrophic factor in the ischemic area of the cerebral cortex. RESULTS AND CONCLUSION:After 12 hours of reperfusion,the neurobehavioral score in the model group was significantly higher than that in the sham-operated group(P＜0.01),while the score in the moxibustion pretreatment group was significantly lower than that in the model group(P＜0.01)and moxibustion pretreatment+EX527 group(P＜0.05).There were no obvious infarct foci in the brain tissue of the sham-operated rats,but obvious ischemic foci were observed in the right side of the brain tissue of the rats in the model group(P＜0.01).The right infarct volume in the moxibustion pretreatment group was significantly reduced compared with the model group(P＜0.01),while the right infarct volume in the moxibustion pretreatment+EX527 group was significantly enlarged compared with the moxibustion pretreatment group.After 12 hours of reperfusion,the level of malondialdehyde was significantly elevated(P＜0.01)and the expression of superoxide dismutase was significantly decreased(P＜0.01)in the model group compared with the sham-operated group.The levels of malondialdehyde was significantly decreased(P＜0.01,P＜0.05)and the expression of superoxide dismutase was significantly increased(P＜0.01,P＜0.05)in the moxibustion pretreatment group compared with the model group and the moxibustion pretreatment+EX527 group.Western blot results showed that the expression levels of SIRT1,FoxO3,p-FoxO3,and brain-derived neurotrophic factor proteins were significantly higher in the model group compared with the sham-operated group(P＜0.01);compared with the model group,the expression levels of SIRT1,FoxO3,and brain-derived neurotrophic factor were significantly higher in the moxibustion pretreatment group(P＜0.01),and p-FoxO3 expression was significantly lower(P＜0.01);compared with the moxibustion pretreatment+EX527 group,the expression levels of SIRT1,FoxO3,and brain-derived neurotrophic factor were elevated in the moxibustion pretreatment group(P＜0.05),and no statistically significant difference was found in the p-FoxO3 expression(P＞0.05).To conclude,moxibustion pretreatment can significantly improve neurological function in rats after cerebral ischemia-reperfusion,and the mechanism may be related to the activation of SIRT1/FoxO3 pathway to reduce oxidative stress injury in the rat model of cerebral ischemia-reperfusion.
ABSTRACT
BACKGROUND:It was found that moxibustion can inhibit the inflammatory factors in the serum of rats with cerebral ischemia/reperfusion injury,resist oxidative stress,inhibit cell apoptosis,and effectively reduce cerebral ischemia/reperfusion injury. OBJECTIVE:To observe the effects of different moxibustion intervention time on the expression levels of nucleotide binding oligomerization domain-like protein 3 inflammasome(NLRP3),cysteine aspartase(caspase-1),apoptosis-related speck-like protein,exfoliatin-D protein,interleukin-1β and interleukin-18 in rats with cerebral ischemia/reperfusion injury,and to explore its action mechanism. METHODS:SD rats were randomly divided into sham operation group(n=9)and operation group(n=36).The model of focal cerebral ischemia/reperfusion injury was established by middle cerebral artery occlusion in the operation group.After successful modeling,the rats in the operation group were further divided into model group,moxibustion 10-minute group,moxibustion 15-minute group and moxibustion 30-minute group,with 9 rats in each group.Rats in the moxibustion 10-minute,15-minute and 30-minute groups were given moxibustion at"Baihui,Dazhui and Zusanli",respectively,once a day for a total of 7 days.The neurological deficits of rats were evaluated by LONGA method.The cerebral infarction was observed by 2,3,5-triphenyltetrazolium chloride staining.The pathological changes of brain tissue were observed by hematoxylin-eosin staining.The contents of interleukin-1β and interleukin-18 in serum of rats in each group were detected by ELISA.Immunohistochemistry and western blot assay were used to detect the expression levels of NLRP3,caspase-1,apoptosis-related spot-like protein and gasdermin D in the ischemic cortex of rats in each group. RESULTS AND CONCLUSION:Compared with the sham operation group,the neurological deficit score of the model group was significantly increased(P<0.01).Compared with the model group,the neurological deficit score of the moxibustion groups was significantly reduced(P<0.01).Compared with the sham operation group,the infarct volume of the model group was significantly increased(P<0.01).Compared with the model group,the infarct volume of the moxibustion groups was significantly reduced(P<0.01);the infarct volume of the rats was smallest in the moxibustion 30-minute group(P<0.05).Compared with the model group,the contents of inflammatory factors interleukin-1β and interleukin-18 in the serum of rats in the moxibustion groups were decreased(P<0.01).Compared with the moxibustion 10-minute group,the contents of inflammatory factors in the serum of rats in the moxibustion 30-minute group were significantly decreased(P<0.05).Compared with the model group,the expression of NLRP3,apoptosis-related spot-like protein,Caspase-1 and gasdermin D protein in the ischemic cortex of the moxibustion groups was significantly decreased(P<0.01).Compared with the moxibustion 10-minute and 15-minute groups,the expression of protein in the moxibustion 30-minute group was significantly decreased(P<0.05).It is concluded that moxibustion at Baihui,Dazhui and Zusanli can reduce cerebral ischemia/reperfusion injury,among which moxibustion for 30 minutes has the best effect,and its mechanism may be related to the inhibition of pyroptosis mediated by NLRP3/Caspase-1 pathway.
ABSTRACT
Objective To investigate the effects of microsurgical varicocelectomy on testicular function and sexual function in patients with varicocele.Methods The clinical data of 90 patients with varicocele admitted to our hospital were retrospectively analyzed,and the patients were divided into the laparoscopic group(received laparoscopic varicocelectomy)and the microscopic group(received microsurgical varicocelectomy)according to different surgical methods,with 45 cases in each group.The testicular function and sexual function related indexes including sperm density,normal sperm ratio,rate of sperm motility(grades a+b),forward motility sperm rate,international index of erectile function-5(IIEF-5)score,and the levels of testosterone,follicle-stimulating hormone,luteinizing hormone,and androgen levels before and 6 months after surgery in the two groups were compared.The incidence of complications and recurrence 6 months after surgery in the two groups were counted.Results Compared with those before surgery,the sperm density,forward motility sperm rate,rate of sperm motility(grades a+b),normal sperm ratio,IIEF-5 score,testosterone level,and androgen level 6 months after surgery of patients in the two groups were significantly increased(P<0.05),and the levels of luteinizing hormone and follicle-stimulating hormone were decreased(P<0.05).Compared with the laparoscopic group,the levels of follicle-stimulating hormone and luteinizing hormone,and incidence of complications 6 months after surgery of patients in the microscopic group were decreased(P<0.05),and the levels of testosterone and androgens,and IIEF-5 score 6 months after surgery were increased(P<0.05).There was no significant difference in the recurrence rate between the two groups(P>0.05).Conclusion Microsurgical varicocelectomy can improve the testicular function and sexual function of patients with varicocele,with a low incidence of complications.

AIM: To evaluate clinical efficacy and safety of ultrasound cycloplasty(UCP)in the treatment of refractory glaucoma.METHODS:From June 2021 to October 2022, a total of 17 patients(17 eyes)with refractory glaucoma were enrolled in this prospective study, and they all underwent UCP. The patients underwent 6 mo followed-up post-treatment, and the intraocular pressure(IOP), pain grade score, IOP lowering drugs, success rate and occurrence of complications were documented.RESULTS:The IOP was significantly decreased from 51.98±7.80 mmHg before UCP to 32.54±13.21 mmHg at 1 d, 22.38±11.98 mmHg at 1 wk, 22.63±10.78 mmHg at 1 mo, 26.05±9.17 mmHg at 3 mo, and 23.73±9.60 mmHg at 6 mo postoperatively(all P<0.01). The percentage of IOP reduction after treatment was 36.25%, 57.10%, 56.35%, 49.16% and 54.09% at 1 d, 1 wk, 1, 3, and 6 mo, respectively. The pain grade scores were decreased(P<0.01). There was a statistically significant reduction in the use of IOP lowering medications(P=0.008). At 6 mo postoperatively, 2 eyes(12%)were complete success, 11 eyes(65%)were qualified success, and 4 eyes(24%)were failure. The main complication observed was anterior chamber inflammation in 1 eye(6%), foreign body sensation in 2 eyes(12%), subconjunctival hemorrhage in 2 eyes(12%), and conjunctival congestion in 6 eyes(35%). All symptoms spontaneously resolved within 1 wk without requiring any specific treatment. One case of choroidal detachment(6%)occurred on 10 d postoperatively, but recovered after orally treated by prednisone acetate for 1 mo. No other serious complications, such as hyphema, corectopia, synechia or macular edema were reported.CONCLUSION:UCP is safe and efficacious in treating refractory glaucoma, reducing IOP and alleviating ocular pain symptoms, while maintaining a favorable safety profile.

Wilson's disease （WD） is a copper metabolism disorder caused by mutations in the ATP7B gene， with diverse phenotypes and complex pathogenesis. It is one of the few rare diseases that can achieve good clinical efficacy through standardized treatment. Since there are few systematic reviews of this disease， we summarize the pathogenesis and treatment methods of WD from traditional Chinese and western medicine by reviewing the literature related to WD. In western medicine， ATP7B gene mutation is considered as the root cause of WD， which affects copper transport and causes copper metabolism disorders. The excessive copper deposited in the body will result in oxidative stress， defects in mitochondrial function， and cell death. Western medicine treatment of WD relies mainly on drugs， and copper antagonists are the first choice in clinical practice， which are often combined with hepatoprotective and antioxidant therapy. Surgery is a common therapy for the patients with end-stage WD， and gene therapy provides an option for WD patients. According to the traditional Chinese medicine （TCM） theory， WD is rooted in constitutional deficiency and copper accumulation and triggered by dampness-heat accumulation or phlegm combined with stasis. The patient syndrome varies in different stages of the disease， and thus the treatment should be based on syndrome differentiation. The TCM treatment method of nourishing the liver and kidneys and warming the spleen and kidneys can address the root cause. The methods of clearing heat and drying dampness， resolving phlegm and dispelling stasis， and soothing liver and regulating qi movement can be adopted to treat symptoms. On the basis of syndrome differentiation， special prescriptions for the treatment of WD have been formulated， such as Gandou decoction， Gandouling， and Gandou Fumu decoction， which have been widely used in clinical practice. TCM and western medicine have their own advantages and shortcomings. The integrated Chinese and western medicine complementing with each other demonstrates great therapeutic potential. This paper summarizes the pathogenesis and treatment of WD with integrated Chinese and western medicine， aiming to provide a reference for the clinical diagnosis and treatment of this disease.
ABSTRACT
The correlation between intestinal flora and diseases has become a hot research topic in recent years.Since the incidence of diabetes is closely related to chronic low-grade inflammation and intestinal flora disorders,the intervention of intestinal flora imbalance has become a research focus in the prevention and treatment of diabetes mellitus.Akkermansia muciniphila(A.muciniphila) stands out among the intestinal flora as it can alleviate the diabetes-related symptoms by regulating glucagon-like peptide 1 (GLP-1) level,improving intestinal barrier function,and inhibiting chronic inflammation,which is a potential target for the prevention and treatment of diabetes.The reduction in the abundance of A.muciniphila is a marker for the early diagnosis of diabetes.The available studies have demonstrated that the administration with A.muciniphila alone can significantly attenuate inflammation and other related symptoms of diabetic patients.Moreover,A.muciniphila has good safety and can be tolerated by human body.Therefore,A.muciniphila has the potential to serve as a new species of probiotics for the treatment of diabetes.The clinical measures for treating diabetes,such as metformin,Chinese herbal medicines,and functional diet,have been confirmed to be associated with the increased abundance of A.muciniphila.Among them,Chinese herbal medicines can treat diabetes via multiple targets and pathways in a systemic manner.Studies have reported that A.muciniphila is a potential target of Chinese herbal medicines intervening in diabetes.After the administration of Chinese herbal medicines,the improvement of diabetes-related indicators was positively correlated with the abundance of A.muciniphila.The above evidence provides a new idea for the research on the interaction between Chinese herbal medicines and intestinal flora in the treatment of diabetes.Therefore,this paper reviewed the role of A.muciniphila in diabetes and the correlation between the abundance of A.muciniphila and the administration of Chinese herbal medicines,aiming to provide new measures for the prevention and treatment of diabetes.

Independent sample t-test, Chi-squared test, Fisher s exact probability method and nonparametric Mann Whitney U-test were used for statistical analysis, and multivariate Logistic regression was used to analyze the influencing factors of scoliosis.@*Results@#The on the spot detection rate of scoliosis abnormality was 7.4% and the prevalence was 2.2%, mainly for thoracolumbar scoliosis (60.4%) and the scoliosis angle of 10° -<20°(88.1%). The results showed that the detection rate of scoliosis in boys was 1.6% and in girls was 3.3%, with a statistically significant difference ( χ 2=11.84, P < 0.01). There were significant differences in weight and BMI between scoliosis students and students with negative initial screening( t = -3.77, -5.30, P <0.01). And there was a statistically significant difference in the detection rate of scoliosis with different frequency of classroom seating arrangements ( Z =2.02, P <0.05). The results of multivariate Logistic regression showed that the risk of scoliosis in girls was higher than that in boys ( OR =1.87, 95% CI =1.21-2.88). BMI ( OR =0.89, 95% CI =0.83-0.95) and frequency of classroom seating arrangements ( OR =0.49, 95% CI =0.25-0.93) were correlated with lower rate of scoliosis. After stratification by sex, the frequency of classroom seating arrangements ( OR =0.26, 95% CI =0.10-0.67) in boys and the educational stage ( OR =2.35, 95% CI =1.26-4.41) in girls ( P <0.05) was correlated with higher rate of scoliosis, while BMI ( OR =0.86, 95% CI =0.79-0.94) in girls were correlated with lower rate of scoliosis.@*Conclusion@#Regular screening of scoliosis is an effective method for early detection of scoliosis. Girls in junior high school and low BMI should be paid close attention to. According to the occurrence and influencing factors of scoliosis, comprehensive prevention and control based on family, school, society, and other aspects can be carried out.
ABSTRACT
Objective: To investigate the relationship between serum lysophosphatidylcholine (LPC) level and the health index of the elderly. Methods: A total of 251 subjects were selected from the 2016 baseline survey of the Yongfu Longevity Cohort in Guangxi Province among whom 66, 63 and 122 were in the young and middle-aged group (≤59 years old), the young group (60-89 years old) and the longevity group (≥90 years old), respectively. Demographic data were collected and related indicators of height, weight, blood pressure and lipid metabolism were measured. The cognitive and physical functions of the elderly were assessed by the results of the simple mental state scale and the daily living activity scale to construct the health index of the elderly. The serum levels of LPC16∶0, LPC18∶0, LPC18∶1 and LPC18∶2 were determined by liquid chromatography-tandem mass spectrometry, and the differences among different ages and health status groups were compared. The logistic regression model was used to analyze the relationship between the serum LPC level and the health index of the elderly. Results: With the increase in age, the proportion of female subjects increased, and the rate of smoking and drinking decreased. BMI, TC, TG, LDL-C, diastolic blood pressure, and the four LPCs levels decreased with the increase of age, and systolic blood pressure levels increased with the increase of age (all P values<0.05). There was no significant difference in HDL-C levels among age groups (P>0.05). With the decline of health status in the elderly, serum levels of LPC16∶0, LPC18∶0, LPC18∶1 and LPC18∶2 showed a downward trend (all P values<0.001). After adjusting for age and gender, only LPC18∶0 was associated with the health status in old age [OR (95%CI): 0.48 (0.25-0.92)]. For every 1 standard deviation (16.87 nmol/L) increase in serum LPC18∶0 concentration, the risk of poor health status in old age decreased by 52%. Conclusion: Serum LPC18∶0 was associated with the health status in old age independent of age and sex.

ABSTRACT
Objective:To explore the correlation between the triglyceride glucose (TyG) index and the risk of vitamin D deficiency (VDD) in patients with type 2 diabetes (T2DM).Methods:T2DM patients admitted to the Department of Geriatrics, the Second Xiangya Hospital of Central South University from February 2020 to February 2023 were included. We collected general clinical and biochemical data from patients and calculated the TyG index. Divide the study subjects into VDD group and control (CON) group based on serum 25 hydroxyvitamin D [25 hydroxyvitamin D, 25(OH)D] levels, and compare the general clinical characteristics between the two groups; Pearson rank correlation analysis was used to study the correlation between TyG index and 25(OH)D; According to the third percentile of the TyG index, the study subjects were divided into three groups (Q1, Q2, Q3), and logistic regression analysis was used to explore the association between the TyG index and the risk of VDD.Results:This study included 526 patients with T2DM, including 312 males and 214 females, aged 37 to 78 years old. There were 300 VDD patients, accounting for 57.03%, and 226 in the CON group. The TyG index of VDD patients was higher than that of the CON group ( P<0.05), and there was a negative correlation between the TyG index and serum 25(OH)D levels ( P<0.05). Logistic regression analysis showed that compared with the Q1 group, the risk of VDD in Q3 group patients was 2.892 times higher than that in Q1 group ( OR=2.892, 95% CI: 1.865-4.485, P<0.001). After adjusting for age, gender, smoking, obesity, insulin, oral hypoglycemic drugs, statin use, and blood biochemical indicators, the risk of illness in the Q3 group was 2.303 times higher than that in the Q1 group ( OR=2.303, 95% CI: 1.288-4.117, P=0.005). Conclusions:In T2DM patients, the TyG index is negatively correlated with serum 25 (OH) D levels. T2DM patients with high TyG index have an increased risk of VDD, and the TyG index can be used to observe the possibility of VDD occurrence, which is beneficial for early detection of VDD patients.
ABSTRACT
Objective:To investigate the prevalence of influenza, pneumococcal, hepatitis B virus (HBV), human papillomavirus (HPV), and varicella zoster virus (VZV) vaccination in patients with systemic lupus erythematosus (SLE), and to analyze the factors related to vaccination.Methods:Data were obtained from 1 203 patients with SLE, via a multi-center web-based survey using an online questionnaire. Data about their social conditions, clinical presentations, willingness for being vaccinated, vaccination within 5 years were collected. Demographic data were shown by descriptive analysis. Chi-square and logistic regression analysis were used to assess the power of related indexes as predictors of vaccination.Results:The vaccination rates of influenza, pneumococcal, HBV, HPV, and VZV were 5.49% (66/1 203), 0.66% (8/1 203), 2.08% (25/1 203), 3.82% (46/1 203), and 0.17% (2/1 203), respectively. Data analysis showed that higher education ( χ2=30.94, P<0.001) and higher income ( χ2=10.70, P=0.001) had greater effects on influenza vaccination. There was a relationship between HPV vaccination and higher education ( χ2=20.96, P<0.001), higher income ( χ2=20.56, P<0.001), younger age ( χ2=8.54, P=0.001), and single ( χ2=5.63, P=0.018). Male ( χ2=10.27, P=0.001) and higher education ( χ2=4.52, P=0.034) were associated with HBV vaccination. The multivariate logistic regression analysis revealed that higher education [ OR (95% CI)=2.14 (1.10, 4.18), P=0.026], having children under 18 years-old [ OR(95% CI)=1.802(1.02, 3.18), P=0.042], and hydroxychloroquine usage [ OR(95% CI)=2.55(1.06, 6.15), P=0.037], had a positive correlation with influenza vaccination. Male [ OR(95% CI)=4.24(1.37, 13.08), P=0.012], had an impact on HBV vaccination. The factors related to HPV vaccination included age <45 [ OR (95% CI)=0.93(0.89, 0.97), P=0.001], higher education [ OR(95% CI)=2.28(1.11, 4.65), P=0.024], higher income [ OR(95% CI)=2.68(1.32, 3.41), P=0.006] and the usage of immunosuppressive agents [ OR(95% CI)=1.92(1.03, 3.59), P=0.041]. Conclusion:The prevalence of vaccination in patients with SLE is low. Patients with higher education and income are more likely to being vaccinated.
ABSTRACT
Objective:To reconstruct the three-dimensional (3D) dose distribution in radiotherapy based on the convolutional neural networks (CNN) through multi-perspective scintillation light processing.Methods:First, fluorescence images were captured from three orthogonal perspectives using a complementary metal-oxide-semiconductor (CMOS) imaging sensor. Then, the images were converted into 3D images, which were input to the trained CNN for dose reconstruction. Finally, the reconstructed doses in different fields were evaluated in terms of gamma pass rate, mean-square error (MSE), percentage depth dose (PDD), and cross beam profile (CBP). Additionally, as the CNN model, 3D-Unet was pre-trained on a virtual dataset.Results:With the 50% maximum dose of as the threshold and 3%/3 mm as the standard, the central-plane and stereo-mean gamma pass rates of all field reconstruction distributions were over 90%, with MSEs remained below 1%. Besides, the PDD and CBP curves showed MSEs below 1‰ and below 1%, respectively.Conclusions:The deep learning-based method for 3D dose reconstruction using scintillation light contributes to enhanced verification of instantaneous 3D relative dose based on plastic scintillation detectors.
ABSTRACT
Objective:To examine changes in serum periostin in elderly patients with chronic obstructive pulmonary disease(COPD)and their correlation with blood eosinophils(EOS)and lung function, and to explore whether serum periostin can be used as a biomarker for COPD.Methods:Case-control study, a total of 128 hospitalized elderly patients with COPD were enrolled in the COPD group, and 60 healthy elderly adults receiving physical check-ups were included in the control group between December 2018 and May 2021.Serum periostin, blood EOS, eosinophil percentage(EOS%)and lung function were measured for all participants.In addition, serum periostin in the COPD group was also measured after treatment.Differences in serum periostin, EOS, EOS% and the predicted percentage value of forced expiratory volume in one second(FEV1%pred)as a measure for lung function were compared between the COPD group and the control group, and differences in serum periostin in the COPD group before and after treatment were also compared.Patients in the COPD group were further divided into a mild subgroup, a moderate subgroup and a severe subgroup, and differences in values of the parameters were compared between the subgroups.Multiple linear regression was used to analyze the correlation of serum periostin with blood EOS and FEV1%pred; the correlation between periostin and COPD was analyzed by binary Logistic regression; the correlation between periostin and COPD severity was analyzed by ordered multinomial Logistic regression.Results:Serum periostin, EOS and EOS% in the COPD group were higher than in the control group, FEV1%pred was lower than in the control group(all P<0.05), and post-treatment serum periostin in the COPD group was lower than pre-treatment levels[(103.47±9.58)mg/L vs.(105.20±9.45)mg/L, t=2.830, P=0.005)]. Serum periostin, EOS and EOS% in the moderate and severe subgroups were higher than in the mild subgroup, and their levels in the severe subgroup were higher than in the moderate subgroup.FEVl%pred in the moderate and severe subgroups was lower than in the mild subgroup, while FEVl%pred in the severe subgroup was lower than in the moderate subgroup(all P<0.05). Multiple linear regression analysis showed that serum periostin was positively correlated with blood EOS( β=33.728, P=0.002)and negatively correlated with FEVl%pred( β=-0.208, P=0.001). Logistic regression analysis showed that high serum periostin was a risk factor for COPD( OR=1.079, 95% CI: 1.019-1.143, P=0.009)and also a risk factor for the severity of COPD( OR=1.097, 95% CI: 1.015-1.186, P=0.020). Conclusions:High serum periostin increases the risk of occurrence and aggravation of COPD, serum periostin correlates with blood EOS and lung function and has the potential to become one of the biomarkers for COPD.
ABSTRACT
Hepatolenticular degeneration (HLD) is a rare genetic metabolic disorder of the nervous system with complex and diverse clinical phenotypes and is difficult to diagnose. The common lesions of HLD brain area are basal ganglia, thalamus, cerebellum and other anatomical structures, the classic manifestations of brain magnetic resonance imaging are symmetrical bilateral lenticular nucleus with low signal on T 1WI and high signal on T 2WI, and it is extremely rare for cases with high signal intensity on diffusion weighted imaging (DWI) of the brain stem, bilateral cerebral peduncles, thalamus, and basal ganglia. This article reported a case of HLD with high signal on DWI for clinical reference.
ABSTRACT
Objective:To investigate the workload of doctorsand its influencing factors in the outpatient department of a tertiary public hospital in Beijing, in order to provide references for further improvement of outpatient management.Methods:Data on outpatient workload and basic information of doctors in clinical departments of a tertiary public hospital in Beijing in 2022 were collected. Independent sample t-tests was used to analyze the differences in workload among doctors with different characteristics. Multiple linear regression analysis was conducted to identify the main factors influencing doctors′ outpatient workload. Results:In 2022, the number of patients treated by doctors in clinical departments per half day was 18.4±8.1, the duration of half-day treatment was 3.08±0.40 h, and the treatment time per visit was 11.93±5.19 min. The type of department was found to be a key factor affecting the number of patients, the duration of treatment, and the time per visit in outpatient care. The workload of surgical and internal medicine departments was significantly higher than that of other departments. The workload of doctors with less experience was significantly higher than that of more experienced doctors.Conclusions:The outpatient workload in tertiary comprehensive hospitals is heavy, and it is mainly influenced by the type of department and professional title. Different measures should be implemented for different department types by hospitals and health management departments to optimize the allocation of medical resources and effectively reduce the burden on doctors in tertiary public hospitals.
ABSTRACT
The components of the tumor microenvironment have a complex composition and play an important regulatory role in tumor evolution.The extracellular matrix(ECM)serves as a vital mediator in regulating cancer advancement within the TME.Incorporating ECM into tumor modeling allows for a more comprehensive simulation of the TME in vitro.As a medium for organoid growth,the matrix gel fulfills the functions of ECM.ECM is normally derived from the recombinant basement membrane of mouse sarcoma(Matrigel);however,batch-to-batch variations in Matrigel affect experiment reproducibility.To overcome such issues,researchers have designed synthetic matrix gels.This paper provides an overview of the current research in the application of matrix gels for tumor organoid modeling,offering insights for continuous optimization of organoid culture,thereby achieving more efficient and cost-effective organoid construction and advancing the translation of basic research to clinical applications.
