ObjectiveTo explore the possible action mechanism of Qingshi Anti-itch Ointment （青石止痒软膏， QAO） in the treatment of psoriasis. MethodsForty mice were randomly divided into four groups， blank group， model group， calcipotriol group and QAO group， with 10 mice in each group. Except for the blank group， psoriasis was induced by applying imiquimod cream to the dorsal skin. After modeling for 6 hours daily， the calcipotriol group and QAO group were treated with 0.5 g of calcipotriol ointment or 0.5 g of QAO， respectively， applied to the treated dorsal skin. The blank group and the model group received no treatment. The skin lesions were observed， and the psoriasis area and severity index （PASI） score was assessed every other day. After 7 days， Hematoxylin and Eosin （HE） staining was performed on dorsal skin tissue to observe pathological changes. The levels of interleukin 1β （IL-1β） and interleukin 18 （IL-18） were determined by enzym-linked immunosorbent assay （ELISA）. The protein levels of Caspase-1，Pro-Caspase-1， gasdermin D （GSDMD） and gasdermin-D-N （GSDMD-N） were detected by Western Blot （WB）. The protein levels of GSDMD were observed by immunohistochemistry. ResultsCompared with the blank group， the model group mice showed redness， erythema， and white scales on their skin， with histological observations indicating epidermal thickening， elongated spines， and infiltration of inflammatory cells. The PASI scores of the skin tissue on days 1， 3， 5， and 7 were elevated； the IOD and AOD values of GSDMD protein increased； the protein levels of Caspase-1， Pro-Caspase-1，GSDMD， GSDMD-N， and IL-1β and IL-18 were significantly elevated （P＜0.05 or P＜0.01）. Compared with the model group， the QAO group and calcipotriol group showed lighter skin lesions； the PASI scores on day 5 and day 7 in the QAO group， and on day 3， 5， and 7 in the calcipotriol group， were reduced； the IOD and AOD values of GSDMD protein， and the protein level of Caspase-1， GSDMD， and GSDMD-N， as well as level of IL-18 and IL-1β decreased in both groups； in the calcipotriol group， Pro-Caspase-1 protein level also decreased （P＜0.05 or P＜0.01）. Compared with the calcipotriol group， the QAO group showed slightly redder skin， more obvious thickening of the stratum corneum， and less capillary dilation； the PASI scores on day 3 and day 7 increased， while the score on day 5 was reduced； the protein level of Pro-Caspase-1， GSDMD， GSDMD-N， and the level of IL-18 and IL-1β were increased in the QAO group （P＜0.05）. ConclusionQAO can effectively relieve psoriasis dermatitis in mice. Its potential mechanism may be related to the regulation of the Caspase-1/GSDMD protein pathway， down-regulation of IL-18 and IL-1β levels， and alleviation of pyroptosis.

ObjectiveTo evaluate the clinical efficacy and safety of Huaban Jiedu Formulation （化斑解毒方， HJF） in treating psoriasis vulgaris with blood-heat syndrome. MethodsA randomized， double-blind， placebo-controlled study was conducted with 60 patients diagnosed with psoriasis vulgaris of blood-heat syndrome. Patients were randomly assigned to either a treatment group or a control group， with 30 cases in each. The treatment group received HJF granules orally， one dose a day， combined with topical Qingshi Zhiyang Ointment （青石止痒软膏）， while the control group received placebo granules， one dose a day， combined with the same topical ointment. Both groups were topically treated twice daily of 28 days treatment cours. Psoriasis area and severity index （PASI）， visual analogue scale for pruritus （VAS）， traditional Chinese medicine （TCM） syndrome scores， dermatology life quality index （DLQI）， and psoriasis life stress inventory （PLSI） were assessed before treatment and on day 14 and day 28. Response rates for PASI 50 （≥50% reduction） and PASI 75 （≥75% reduction）， as well as overall clinical efficacy， were compared between groups. Serum levels of interleukin-6 （IL-6） and interleukin-17 （IL-17） were measured before and after 28 days of treatment. Adverse reactions during treatment were recorded. ResultsAfter 28 days of treatment， both groups showed significant reductions in PASI total score， lesion area score， erythema， scaling， and infiltration scores， pruritus VAS score， TCM syndrome score， DLQI， PLSI， and serum IL-6 and IL-17 levels （P＜0.05）. Compared to the control group， the treatment group had significantly greater improvements in PASI total score and erythema score， TCM syndrome score， serum IL-6 and IL-17 levels， and PASI 50 response rate after 28 days （P＜0.05）. Between-group comparisons of score differences before and after 28-day treatment revealed that the treatment group showed significantly better improvements in PASI total， lesion area score， erythema score， TCM syndrome score， DLQI， PLSI， and inflammatory markers （P＜0.05 or P＜0.01）. The total effective rate on day 14 and day 28 was 40.00% （12/30） and 83.33% （25/30） in the treatment group， versus 6.90% （2/29） and 41.38% （12/29） in the control group， respectively. The clinical efficacy in the treatment group was significantly superior to that in the control group （P＜0.05）. Mild gastric discomfort occurred in 3 patients in the treatment group and 1 in the control group. ConclusionHJF can effectively improve skin lesions and TCM symptoms relieve pruritus， enhance quality of life， and reduce inflammatory markers IL-6 and IL-17， in patients with blood-heat syndrome of psoriasis vulgaris， with a good safety profile.

Parkinson’s disease (PD) is a neurodegenerative disease characterized by various motor and non-motor symptoms. The complexity of its symptoms suggests that PD is a heterogeneous neurological disorder. Its pathological changes are not limited to the substantia nigra-striatal system, but gradually extending to other regions including the cerebellum. The cerebellum is connected to a wide range of central nervous system regions that form essential neural circuits affected by PD. In addition, altered dopaminergic activity and α-synuclein pathology are found in the cerebellum, further suggesting its role in the PD progression. Furthermore, an increasing evidence obtained from imaging studies has demonstrated that cerebellar structure, functional connectivity, and neural metabolism are altered in PD when compared to healthy controls, as well as among different PD subtypes. This review provides a comprehensive summary of the cerebellar pathophysiology and results from neuroimaging studies related to both motor and non-motor symptoms of PD, highlighting the potential significance of cerebellar assessment in PD diagnosis, differential diagnosis, and disease monitoring.

Pathological,electrophysiological,and neuroimaging changes in the cerebellum can occur in neurodegenerative diseases such as Alzheimer disease,Parkinson disease,and amyotrophic lateral sclerosis.The activation and neurodegeneration of neurons in specific cerebellar regions may contribute to the clinical symptoms and pathological processes of these neurodegenerative diseases.This article reviews the clinical assessment methods and neuroimaging studies related to cerebellar symptoms in neurodegenerative diseases.The findings suggest that structural and functional abnormalities of the cerebellum are associated with symptoms such as motor,cognitive,and emotional dysfunction in these diseases.Developing a multidimensional,systematic clinical and imaging evaluation approach centered on the cerebellum will help deepen our understanding of the cerebellum's role in the pathogenesis of neurodegenerative diseases.It will also provide new directions for the early identification of symptoms,differential diagnosis,and the formulation of precise treatment plans.

Objective To evaluate the clinical screening value of the Epworth sleepiness scale(ESS)for patients with type 2 diabetes mellitus(T2DM)and obstructive sleep apnea hypopnea syndrome(OSAHS).Methods A total of 399 hospitalized T2DM patients were selected for portable monitoring(PM)and ESS assessment.Based on the presence or absence of OSAHS,the study was divided into a simple T2DM group(T2DM,n=143)and a group with comorbid OSAHS(OSAHS,n=256).According to the apnea-hypopnea index(AHI),the study participants were categorized into a normal group(AHI<5 times/h,n=143),a mild OSAHS group(AHI 5～15 times/h,n=147),a moderate OSAHS group(AHI>15～30 times/h,n=69),and a severe OSAHS group(AHI>30 times/h,n=40).Differences in ESS scores across various OSAHS severity groups were compared.Receiver operating characteristic(ROC)curve analysis was conducted to evaluate the screening value of ESS for OSAHS.Results Body mass index,proportion of obesity,proportion of central obesity,serum creatinine and fasting C-peptide were significantly higher the OSAHS group compared to the non-OSAHS group(P<0.05).Significant statistical differences in ESS scores were observed between the severe and mild OSAHS groups(P=0.006).When an ESS score of≥9 was used as the threshold for screening OSAHS,the concordance rate with PM diagnosis was 40.6%.ROC curve analysis revealed that the area under the curve(AUC)for ESS screening for OSAHS,moderate-to-severe OSAHS,and severe OSAHS,and their respective optimal thresholds(95%CI),were as follows 0.518(95%CI 0.459～0.577,P=0.545),0.571(95%CI 0.507～0.635,P=0.029)and 0.624(95%CI 0.531～0.718,P=0.010),with cutoffs of≥2 points,≥3 points,and≥4 points,respectively.Conclusions An increased ESS score in T2DM patients significantly indicates the likelihood of severe OSAHS.Using an ESS score of≥9 as a threshold to screen for OSAHS is ineffective,whereas an ESS score of≥3 for screening moderate-to-severe OSAHS and≥4 for severe OSAHS has some reference value.

Objective:To evaluate the value of preoperative vascular ultrasound parameters in predicting the postoperative lower extremity deep venous thrombosis (DVT) in patients with gynecological malignant tumors.Methods:Ninety-nine patients with gynecological malignant tumors, aged>18 yr, with body mass index<30 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective surgery under general anesthesia, were selected. Vascular ultrasound examination was performed before surgery. The flow velocity and diameter of common femoral vein (CFV), deep femoral vein (DFV), popliteal vein (POV), and intermuscular vein (IMV) were recorded. Ultrasound examination of lower limb veins (including anterior tibial vein, posterior tibial vein, IMV, CFV, DFV, POV) were conducted at 1-8 days after surgery to determine whether a DVT occurred. The receiver operating charcateristic curve was used to evaluate the accuracy of each indicator in predicting the lower extremity DVT, and the cut-off value was determined based on the maximum principle of Jorden index. Results:The incidence of lower extremity DVT was 13.1%. The area under the curve (95% confidence interval) of the preoperative CFV flow velocity and diameter, DFV flow velocity and diameter, POV flow velocity and diameter, IMV flow velocity and diameter in predicting the lower extremity DVT were 0.769 (0.616-0.923) and 0.800 (0.644-0.950), 0.797 (0.641-0.954) and 0.771 (0.596-0.945), 0.806 (0.645-0.968) and 0.754 (0.606-0.903), 0.764 (0.615-0.914) and 0.818 (0.645-0.990), respectively ( P<0.05), and the predicted cut-off values were 27.13 cm/s and 11.93 mm, 19.31 cm/s and 10.15 mm, 16.04 cm/s and 8.79 mm, 14.39 cm/s and 8.68 mm, respectively, and the sensitivity and specificity were 90.0%, 71.4% and 90.0%, 74.3%; 90.0%, 74.3% and 90.0%, 68.6%; 90.0%, 82.9% and 90.0%, 72.9%; 90.0%, 70.0% and 80.0%, 87.1%, respectively. Conclusions:Preoperative vascular vascular ultrasound parameters can accurately predict the occurrence of postoperative lower extremity DVT in patients with gynecological malignant tumors.

Objective To investigate the effect of hemoperfusion combined with sequential hemodiafiltration on pancreatic islet β cell function,nutritional status and inflammatory response in patients with diabetic nephropathy(DN).Methods One hundred patients with DN admitted to Nanyang Central Hospital from February 2022 to February 2023 were selected as the research subjects.They were divided into the control group and the observation group according to the random number table method,with 50 patients in each group.The patients in the control group were treated with sequential hemodiafil-tration,and the patients in the observation group were treated with sequential hemodiafiltration combined with hemoperfusion.The weight and height of patients in the two groups were measured before treatment and after 6-month treatment to calculate body mass index(BMI).The triceps skinfold(TSF)thickness was measured by using a skinfold caliper.The nutritional status of patients were evaluated by subjective global assessment(SCA)scores.Fasting venous blood was collected from patients in the two groups to measure the levels of fasting insulin(FINS)and fasting plasma glucose(FPG)by radioimmunoassay,and the homeostasis model assessment of insulin resistance(HOMA-IR)and homeostasis model assessment of beta-cell function(HOMA-β)were calculated;the levels of total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C)and low-density lipoprotein cholesterol(LDL-C)were measured by using the fully automatic biochemical analyzer,and the levels of serum C-reactive protein(CRP),tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)were measured by using the enzyme-linked immunosorbent assay.Results There was no significant difference in HOMA-β,FINS and HOMA-IR of patients between the control group and the observation group before treatment(P＞0.05).FINS and HOMA-IR of patients after treatment were significantly lower than those before treatment,while HOMA-β was significantly higher than that before treatment in the two groups(P＜0.05).After treatment,FINS and HOMA-IR of patients in the observation group were significantly lower than those in the control group,while HOMA-β was significantly higher than that in the control group(P＜0.05).There was no significant difference in BMI,TSF and SGA of patients between the control group and the observation group before treatment(P＞0.05).After treatment,BMI,TSF and SGA of patients in both groups were significantly higher than those before treatment;and BMI,TSF and SGA of patients in the observation group were significantly higher than those in the control group(P＜0.05).There was no significant difference in the levels of TC,TG,LDL-C and HDL-C of patients between the control group and the observation group before treatment(P＞0.05).After treatment,the levels of TC,TG and LDL-C of patients in both groups were significantly lower than those before treatment,while the HDL-C level of patients was significantly higher than that before treatment(P＜0.05).After treatment,the levels of TC,TG and LDL-C of patients in the observation group were significantly lower than those in the control group,while the HDL-C level of patients was significantly higher than that in the control group(P＜0.05).There was no significant difference in the levels of serum CRP,TNF-α and IL-6 of patients between the control group and the observation group before treatment(P＞0.05).After treatment,the levels of serum CRP,TNF-α and IL-6 of patients in both groups were significantly lower than those before treatment;and the levels of serum CRP,TNF-α and IL-6 of patients in the observation group were significantly lower than those in the control group(P＜0.05).Conclusion Sequential hemodiafiltration combined with hemoperfusion can significantly improve pancreatic islet βcell function,nutritional status and lipid metabolism in patients with DN and inhibit inflammatory response.

Objective To investigate the changes in motor symptoms and cognitive levels in α-synuclein A53T transgenic mice at different months of age and possible mechanisms.Methods The α-synuclein A53T transgenic mice and wild C57/BL6J mice,aged 6 months,were selected.The open field test and the rotarod test were used to observe the motor function and emotional response of mice;fear conditioning and the novel object recognition test were used to observe the cognitive function of mice;Western blotting was used to measure the expression level of M1 cholinergic receptor in the hippocampus of the mice in the two groups,and the transcriptome method was used to observe the difference in gene ex-pression in the hippocampus between the two groups.Results Behavioral experiments showed that compared with the wild-type mice,the A53T transgenic mice showed cognitive dysfunction at 12 months of age[novel object recognition test:(36.74±13.33)vs(46.90±6.58),t=-2.368,P=0.027],and this phenomenon occurred before motor symptoms.West-ern blotting showed that there was no significant difference in the level of M1 cholinergic receptor in the hippocampus be-tween the A53T transgenic mice and the wild-type mice(P=0.537).The transcriptome analysis identified 290 differen-tially expressed genes between the two groups,among which there were 20 genes with significant difference,and the sig-nificantly downregulated gene sets in the hippocampus of A53T mice were mainly involved in anti-cellular inflammatory re-sponse and antioxidant level.Conclusion Cognitive dysfunction in A53T transgenic mice occurs earlier than motor symp-toms,with a relatively late time node.Transcriptome tests suggest that cellular inflammatory response and oxidative stress injury might be involved in the early pathological process of cognitive impairment in A53T mice.

Purpose To explore the application value of clinical-ultrasound parameter model in secondary hyperparathyroidism(SHPT).Materials and Methods A total of 86 patients(134 lesions)with renal insufficiency who underwent maintenance hemodialysis in the First Affiliated Hospital of Shihezi University from October 2020 to August 2022 were included and divided into group 1 according to the level of parathyroid hormone(iPTH)(iPTH＜300 pg/ml),group 2(iPTH 300-800 pg/ml)and group 3(iPTH≥800 pg/ml),all patients underwent gray-scale parathyroid ultrasound and acoustic palpation tissue quantitative imaging examinations.The characteristics of glandular gray-scale ultrasound and virtual touch tissue imaging quantification parameters between different groups,combined with relevant clinical indicators,established a clinical-ultrasound parameter model,used multiple linear regression to analyze the correlation between the model and iPTH,explored the independent risk factors of iPTH,and evaluated this model to evaluate SHPT the value of.Results There were significant differences in dialysis age,phosphorus,alkaline phosphatase,serum creatinine,corrected calcium and phosphorus product,lesion size,number,echo,shear wave velocity(SWV)max,SWVcen,and SWVmean among the three groups(F/x2/H=6.396-53.524,all P＜0.05).Dialysis age,phosphorus,alkaline phosphatase,and SWVratio were independent influencing factors of iPTH level(β=0.514,0.422,0.226,-0.368,all P＜0.005).The area under the curve,sensitivity,specificity and accuracy of the model for diagnosing SHPT and predicting surgical treatment with iPTH levels of 300 pg/ml and 800 pg/ml were 0.967,95.00％,100.00％,97.73％and 0.824,77.42％,71.43％and 90.00％,respectively.Conclusion Dialysis age,phosphorus,alkaline phosphatase and SWVratio are independent influencing factors of iPTH level,and the clinical-ultrasound parameter model is of great value in accurately assessing the severity of SHPT.
