ObjectiveTo observe the clinical efficacy and safety of Guben Quyu Jiedu prescription in treating nocturnal hypoxemia of chronic obstructive pulmonary disease （COPD） combined with Obstructive sleep apnea hypopnea syndrome （ OSAHS ） （deficiency of lung， spleen and kidney with blood stasis and toxicity）. MethodsThe paper used a forward-looking， random double-blind， placebo-controlled design method to select 96 patients with COPD combined with OSAHS， and their traditional Chinese medicines （TCM） syndrome differentiation was deficiency of lung， spleen and kidney with blood stasis and toxicity. These patients were randomly divided into the observation group and the control group， with 48 cases in each group. Based on conventional Western medicine treatment， the observation group was treated with Guben Quyu Jiedu prescription and the control group was treated with traditional Chinese medicine placebo. Both courses of treatment were 90 days. Then the paper compared the changes in minimum pulse oxygen saturation （SpO₂） during the night， apnea index （AHI）， OSAHS efficacy evaluation， TCM syndrome efficacy evaluation， and TCM symptom score before and after treatment between the two groups. ResultsThere were 5 withdrawals in the observation group and 8 withdrawals in the control group， so 43 cases in the observation group and 40 cases in the control group completed the trial. Compared with the condition before treatment， the minimum SpO₂ during the night and AHI in the observation group were significantly improved at night （P<0.01） and were better than those in the control group （P<0.01）. OSAHS efficacy in the observation group was better than in the control group （χ²=7.085， P<0.05）. In terms of TCM syndrome efficacy， the total effective rate was 81.40% （35/43） in the observation group， significantly higher than that in the control group， which was 15.00% （6/40） （χ²=36.78， P<0.01）. The TCM symptom scores of the two groups were improved compared with the condition before treatment， and the effect of the two groups was similar in the four main symptoms of snoring， choking， lethargy， and cough. However， the observation group was better than the control group in 10 details such as dizziness， headache， chest tightness， chest pain， wheezing， dry mouth， and thirst （P<0.05）. ConclusionUsing Guben Quyu Jiedu prescription combined with conventional Western medicine can treat COPD combined with OSAHS hypoxemia at night （deficiency of lung， spleen and kidney with blood stasis and toxicity）. In this way， the minimum pulse oxygen saturation （SpO₂） of patients， the level of disease control， and the quality of life of patients can be improved， and the clinical symptoms can be relieved.

China is currently in an accelerated stage of population aging, and brain diseases pose a significant threat to the health of the elderly. " Preventing brain aging and maintaining brain health" has become a high-level goal of healthy aging. During the process of aging, the physiological and psychological states of elderly people change, making them prone to nervousness and exhaustion, which can disturb the brain spirit, damage the brain collaterals, and severely endanger brain health. Starting from the holistic view of cultivating both body and spirit in traditional Chinese medicine, based on the physical and mental characteristics of the elderly, this paper applies the concept and method of " relaxation and tranquility" in the protection of elderly brain health, focusing on maintaining relaxation and tranquility in both physical and mental aspects. Specific measures include emphasizing subjective consciousness, relaxing the heart and calming down; utilizing the daoyin method, relaxing the body and calming down, combining relaxation and tranquility, cultivating both body and spirit to prevent diseases and protect the brain, which enables the elderly to have a healthy mind and body, a sense of happiness and fulfillment, and to age gracefully. Simultaneously, advocating for tranquility is also called " respect" for relaxation, following nature to understand constant changes, and improving one′s ability to think positively in old age, in order to expand ideas for the protection of elderly brain health.

The incidence of gestational diabetes mellitus (GDM) is gradually increasing and has become a significant public health issue. Endocrine disrupting chemicals (EDCs) are a ubiquitous class of exogenous chemical substances that can interfere with hormone synthesis, metabolism, and activity, and subsequently affect endocrine homeostasis. Humans are extensively and continuously exposed to various EDCs originating from food packaging, plastic products, textiles, electronic goods, as well as cleaning agents and cosmetics in daily life, leading to endocrine and metabolic disorders, such as obesity, insulin resistance, impaired glucose tolerance, and diabetes. Previous studies indicated a close association between EDCs exposure and the occurrence of GDM. This review summarized the correlation between daily life exposure to EDCs and GDM, along with their potential biological mechanisms, including bisphenols, phthalates, per- and polyfluoroalkyl substances, organophosphate esters, parabens, and triclosan, aiming to provide scientific evidence for supporting the effective implementation of public health intervention measures to alleviate and prevent GDM.

OBJECTIVE To evaluate the clinical efficacy and safety of Xiaoyin capsules combined with secukinumab in the treatment of moderate to severe plaque psoriasis. METHODS A retrospective study was conducted on 105 patients with moderate to severe plaque psoriasis who received treatment in the Dept. of Dermatology of Xinxiang Central Hospital from January 2021 to June 2024. According to the treatment plan， they were divided into conventional group（n＝32）， monoclonal antibody group（n＝45）， and combination group（n＝28）. The conventional group was given Calcipotriol ointment+Fluticasone propionate cream+Acitretin capsules； the monoclonal antibody group was treated with secukinumab injection in addition to the treatment of the conventional group； the combination group received oral administration of Xiaoyin capsules in addition to the treatment of the monoclonal antibody group. All patients received at least 12 weeks of treatment. The psoriasis area and severity index（PASI） score， PASI improvement rate， dermatology life quality index（DLQI） score， physician’s global assessment（PGA） score， patient’s global assessment（PtGA） score before and after treatment， and the incidence of adverse reactions during treatment were compared among the three groups. RESULTS Before treatment， there was no statistically significant difference in the above scores among the three groups（P＞0.05）. After treatment， the scores of all three groups of patients significantly decreased compared to before treatment （P＜0.05）； the total PASI score and erythema， scales， affected body surface area score， the total DLQI score and symptom perception， daily activity， social score， the PGA and PtGA scores of the combination group were significantly lower than the other two groups（P＜0.05）； PASI 50（the proportion of patients whose PASI score decreased by ≥50% from baseline， and so on）， PASI 75， and PASI 90 were significantly higher than the other two groups（P＜0.05）； the total PASI score， erythema， and affected body surface area score of patients in the monoclonal antibody group were significantly lower than the conventional group（P＜0.05）， and PASI 75 was significantly higher than the conventional group（P＜0.05）. There was no statistically significant difference in the total incidence of adverse reactions among the 3 groups（P＝0.637）. CONCLUSIONS The combination of Xiaoyin capsules and secukinumab can significantly improve the skin lesions and quality of life in patients with moderate to severe plaque psoriasis， with good tolerability in the short term and no significant increasein the risk of serious adverse reactions.

Objective To investigate the relationship between polymorphism of resistin(RETN)gene and metabolic associated fatty liver disease(MAFLD)in type 2 diabetes mellitus(T2DM)patients in middle and high altitude areas.Methods A total of 400 patients with T2DM in Qinghai area were recruited and divided into simple T2DM group(T2DM,n=200)and T2DM combined with MAFLD group(T2DM+ MAFLD,n=200)according to liver ultrasonography.Healthy individuals confirmed by physical examination were selected as the normal control group(NC,n=180).Plasma resistin levels were measured by ELISA.The polymorphism of RETN-420C/G and +299G/A genes were detected by PCR sequencing.Results By comparing the polymorphism of RETN-420C/G gene in each group,it was found that the frequencies of G/G genotype and G allele frequency in T2DM+MAFLD group were higher than those in NC group and T2DM group(P<0.05),while the frequencies of C/C genotype and C allele frequency were lower than those in NC group and T2DM group(P<0.05).The risk of MAFLD increased by 1.571,2.126 and 1.537 times respectively in T2DM patients with C/G,G/G genotype and G allele.Logistic regression analysis showed that G/G genotype was a risk factor for MAFLD in T2DM patients.By comparing the polymorphism of RETN+299G/A gene in each group,it was found that A allele frequency in T2DM+MAFLD group was higher than that in NC group and T2DM group,while G allele frequency was lower than that in NC group and T2DM group(P<0.05).The allele A increased the risk of MAFLD in T2DM patients by 1.432 times compared to allele G.Conclusion RETN gene-420C/G locus G/G genotype increases the risk of T2DM combined with MAFLD in middle and high altitudeareas.

Nuclear factor kappa-B(NF-κB), an intricate nuclear transcription factor, is ubiquitously present within the myriad tissues and cells of the human corpus, engaging in a multiplicity of biological processes such as the development of the immune system, immune responses, inflammatory reactions, angiogenesis, and tumorigenesis. Its cardinal role in the pathogenesis of ocular diseases is increasingly illuminated by its prevalence. Owing to the unique architecture of the ocular globe, burgeoning studies have identified the excessive activation or dysregulation of the NF-κB signaling pathway as intimately associated with the progression of a multitude of ocular conditions, including, but not limited to, cataracts, dry eye syndrome, and glaucoma. The modulation of NF-κB activation, by targeting it, offers a potent mechanism for regulating ocular inflammation and mitigating disease progression, holding promise as a potential therapeutic strategy for ophthalmic disorders. An in-depth examination of the NF-κB signaling pathway's role in ocular diseases not only enriches our comprehension of the underlying mechanisms of these ailments, but also lays a crucial foundation for the innovation of new treatment modalities. Therefore, this article endeavors to provide a compendious review of the regulatory effects exerted by the NF-κB signaling pathway in ophthalmic conditions throughout recent years.

Objective To investigate the application value of spectral computed tomography venography(CTV)in the display and staging of deep venous thrombosis(DVT)in the lower extremity.Methods Eighty-two patients with CTV were selected and ran-domly divided into group A(42 patients)and group B(40 patients).Group A:tube voltage 120 kVp.Group B:gemstone spectral ima-ging(GSI)mode,reconstruction of 50 keV and iodine(water)maps.The CT and standard deviation(SD)values of the veins were measured,signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)were calculated in 120 kVp images of group A and in 50 keV images of group B.Two observers scored the image quality of the 2 groups subjectively,and Kappa test was used to examine the con-sistency.Based on the duration from the occurrence of clinical symptoms,the DVTs were classified.The CT values and iodine con-centration(IC)of DVT were measured in the 120 kVp images of group A and in the iodine(water)maps of group B,respectively.The receiver operating characteristic(ROC)curve was drawn to compare the effectiveness of CT values and IC in diagnosing DVT staging.Results CT values,SNR,and CNR of veins in group B were higher than those in group A(P<0.05).The subjective scores of the two groups were consistent(Kappa=0.926-0.955,P<0.05).The score for the display of veins and thrombus clarity in group B was 5(4,5),which was better than the score of 4(3,4)in group A(P<0.05).The efficiency of IC in diagnosing DVT staging[area under the curve(AUC)=0.973]was better than that of CT values(AUC=0.891).Conclusion The spectral CTV can improve the contrast of lower extremity deep veins and the clarity of thrombus,and can provide more objective indicators for the diagnosis of thrombus staging,which is conducive to accurate clinical diagnosis and treatment.

Objective To explore the value of dynamic nomogram constructed by multi spiral computed tomography(MSCT)features combined with inflammatory indicators in predicting the status of microvascular invasion(MVI)of hepatocellular carcinoma(HCC)before surgery.Methods The clinical and imaging data of 137 patients with postoperative pathologically confirmed HCC were analyzed retrospectively.According to the status of the MVI,they were divided into positive group(44 cases)and negative group(93 cases).Multivariate logistic regression analysis was used to screen independent risk factors for predicting the MVI status of HCC patients,and a joint prediction model was constructed,which was displayed in the form of a dynamic nomogram.The receiver operating characteristic(ROC)curve,calibration curve and Hosmer-Lemeshow test were used to evaluate the diagnostic efficiency,calibration and goodness of fit of the model,Akaike information criterion(AIC)and Bayesian information criterion(BIC)were used for comparison between the models,and a 5-fold cross-validation and decision curve analysis(DCA)were also used to evaluate the stability and clinical applicability of the model.Results Multivariate logistic regression analysis showed that necrosis and delayed-phase enhancement(DEd),and alkaline phosphatase to lymphocyte ratio(ALR)were independent risk factors for predicting MVI status in HCC patients.The area under the curve(AUC)of the dynamic nomogram was 0.721,with the sensitivity of 0.705 and the specificity of 0.656.The AIC and BIC values were 152.372 and 158.212,respectively.The calibration curve and the Hosmer-Lemeshow test showed that the model had a high degree of calibration and goodness of fit(χ2=2.372,P=0.967),the average AUC of the 5-fold cross-validation was 0.787,and the DCA showed that the nomogram model had a good clinical applicability.Conclusion The dynamic nomogram model constructed by MSCT features combined with inflammatory indicators is feasible to predict the MVI status of HCC patients before surgery,and the dynamic nomogram can directly generate the prediction results of different individuals.

Objective:To compare the effects of treatment with Hybrid-Hyrax-Facemask(FM)versus miniscrews in the anterior pal-ate combined with Hybrid-Hyrax-Facemask(MSI/FM)for patients with early Class Ⅲ malocclusion and maxillary deficiency.Methods:18 patients aged with early Class Ⅲ malocclusion and maxillary deficiency were randomly divided into 2 groups(n=9)and treated with FM and MSI/FM respectively.Alternating rapid maxillary expansion and constriction(Alt-RAMEC)protocol combined with a maxillary protraction force of 3.92 N was applied on each side of all patients from elastics connected to the facemask in a down-ward and forward direction of 30° to the occlusal plane.Iortho cephalometric software was used to analyze the data of lateral cephalo-grams of the patients before(T0)and after(T1)treatment.Results:Improvement was verified in the facial profile and occlusion of all patients.In MSI/FM group the average treatment time was shorter.There were significant differences(P＜0.05)between T0 and T1 in the following measurements in FM group:SNA,ANB,Co-A,Co-Gn,Wits,S-Go,Na-Me,MP,U1-SN,UADH,LADH,Overjet,UL-EP increased,U1-L1 decreased.There were significant differences(P＜0.05)between T0 and T1 in the following measurements in the MSI/FM group:SNA,ANB,Co-A,Wits,Na-Me,MP,Y-axis,U1-SN,Overjet,UL-EP increased,SNB,Co-Gn-Co-A,S-Go/N-Me,U1-L1,L1-MP decreased.Conclusion:Both FM and MSI/FM combined with Alt-RAMEC protocol and a maxillary protraction force are effective in the treatment for Class Ⅲ patients with maxillary deficiency.MSI/FM may produce more significant bone effect and re-duce dental compensation,promote more forward growth of midface and more improvement in the growth direction of mandible and re-duce compensatory lip inclination of anterior teeth in shorter treatment time.

Objective To determine the improved effect of methylene blue(MB)on cognitive func-tion in brain-inflammatory-aging rats and investigate the underlying mechanism.Methods A total of 38 healthy 12-month-old SD rats were randomly divided into healthy control group,lipopo-lysaccharide(LPS)group,MB vehicle group and MB group,with 8 rats in the control and 10 rats in the other three groups.LPS was injected into the fourth ventricle with aid of a subcutaneous sustained release pump to establish a rat model of brain chronic inflammatory aging.MB of 0.5 mg/(kg·d)was added into the pump in the rats from the MB group.T-maze test and new object recognition test were employed to evaluate the learning and memory abilities of the rats.The acti-vation of microglia and astrocytes in the hippocampal CA1 region of the rats was detected by im-munofluorescence assay.The release of inflammatory factors IL-1β and IL-6 was measured by ELISA,and neuronal death in the CA1 region was assessed by neuronal nuclei(NeuN)fluores-cence staining.Results There was no significant difference in the exploration time for new and old objects between the LPS group and the MB solvent group(P＞0.05).The MB group spent significantly longer time in exploring the new objects than the old object(22.50±4.32 s vs 11.60± 3.01 s,P=0.000).The alternating selection rate of new arm and expression level of NeuN antigen were significantly decreased,and the expression levels of ionized calcium binding adaptor mole-cule-1(Iba-1)and glial fibrillary acidic protein(GFAP)and the contents of IL-1β and IL-6 were obviously increased(P＜0.05)in the LPS group and the MB vehicle group than the healthy con-trol group.Compared with the MB vehicle group,the MB group had notably increased alternating selection rate of new arms and higher NeuN expression level,and decreased Iba-1 and GFAP ex-pression and IL-1β and IL-6 contents(P＜0.05).Conclusion Subcutaneous administration of MB could significantly inhibit the damages of spatial learning and memory abilities in the LPS-induced brain chronic inflammatory aging rats.The mechanism may be closely associated with MB inhibi-ting inflammatory glial cells and protecting hippocampal pyramidal neurons.
