Objective: To investigate the effect of auricular therapy on sleep improvement and the GABAergic system pathway in a rat model of insomnia and to explore its possible mechanism. Methods: According to the random number table, 60 male SD rats were randomly divided into blank control, model, auricular point sticking, auricular bloodletting, and auricular bloodletting combined with sticking groups, with 12 rats per group. Insomnia was induced by intraperitoneal injection of p-chlorophenylalanine. After establishing the insomnia model, 36 rats were treated once a day with auricular point sticking or bloodletting for 5 consecutive days. After the intervention, the general condition and body weight of rats were observed; the righting reflex test was used to detect the sleep latency and duration; HE staining was used to observe the morphology of hypothalamic neuron cells; and an enzyme-linked immunosorbent assay was used to detect the GABA and glutamate content in rat serum. Immunohistochemistry(IHC) and real-time fluorescence quantitative PCR were used to detect GABA ARα1 and GABA ARγ2 protein and mRNA expression in the hypothalamus of rats, and Western blotting(WB) was used to detect GABA ARα1, GABA ARγ2, GAD65/67, GAT-1, and GABA-T protein expression in the hypothalamus of rats. Results: Compared with the blank control group, the model group had a lower body weight, a significantly shorter sleep duration (P<0.05), severe damage to the morphological structure of hypothalamic neurons with disordered cell arrangement, larger intercellular gaps, enlarged cell bodies, and a vacuolated appearance. All the intervention groups had significantly higher body weight and longer sleep duration than the model group (P<0.05). Compared with the other intervention groups, the auricular point sticking group had a longer sleep duration (P<0.05), and the hypothalamic neuron cells in all intervention groups improved, with the auricular point sticking group showing more apparent improvement. The model group had a lower GABA and higher glutamate contents, and GABA ARα1, GABA ARγ2, and GAD65/67 protein expression in the hypothalamus were lower than in the blank control group. In contrast, GAT-1 and GABA-T protein expression was higher, and GABA ARα1 and GABA ARγ2 mRNA expression was lower (P<0.05). The serum GABA content in the auricular point sticking and auricular bloodletting groups was higher, and the serum glutamate content in the auricular point sticking and auricular bloodletting combined sticking groups was lower than in the model group. GABA ARα1 mRNA expression in the hypothalamus of each intervention group was significantly increased, and GABA ARγ2 mRNA expression in the hypothalamus of the auricular point sticking and auricular bloodletting combined sticking groups increased. GABA ARα1(IHC, WB), GABA ARγ2(WB), and GAD65/67 protein expression in the hypothalamus of the auricular point sticking group increased, whereas GAT-1 and GABA-T protein expression decreased. GABA ARα1 and GABA ARγ2 protein expression(IHC, WB) in the hypothalamus of the auricular bloodletting group increased, whereas GABA-T protein expression decreased. GABA ARγ1(IHC) and GABA ARγ2(WB) protein expression in the hypothalamus of the auricular bloodletting combined sticking group increased, whereas GAT-1 and GABA-T protein expression decreased (P<0.05). Compared with in the inventation groups, the serum GABA content in the auricular point sticking group increased, the serum glutamate content decreased, GABA ARα1 and GABA ARγ2 mRNA expression in the hypothalamus increased, and GABA ARα1(IHC), GAD65/67 protein expression increased. In contrast, GABA-T protein expression decreased (P<0.05), and GABA ARγ2 protein expression(IHC) in the hypothalamus of the auricular bloodletting group increased (P<0.05). Conclusion Auricular therapy, particularly auricular point sticking, may have modulated the GABAergic system pathway by upregulating hypothalamic GABA ARα1, GABA ARγ2, and GAD65/67 protein expression while downregulating GAT-1 and GABA-T protein expression to alleviate symptoms in an insomnia rat model.

Objective: To assess the dynamic changes of microcirculation at acupoints in patients with primary dysmenorrhea and cold congelation and blood stasis syndrome using laser speckle blood flow imaging. Methods: Patients with primary dysmenorrhea and cold coagulation and blood stasis syndrome (primary dysmenorrhea group, n=53) and healthy female college students(control group, n=57) who met the inclusion and exclusion criteria from October 2020 to July 2022 were enrolled at Hebei University of Chinese Medicine. On the premenstrual and first day of menstruation, a laser speckle blood flow imaging system was used to measure the microcirculation blood flow perfusion on the surface of acupoints related to the conception, thoroughfare, and governor vessels, and stomach, spleen, and bladder meridians in the abdomen and lumbosacral regions. The dynamic changes in microcirculation were calculated based on the difference in average blood flow perfusion at each acupoint before and after menstruation. Receiver operating curve (ROC) analysis was used to analyze the diagnostic efficacy of dynamic changes in microcirculation on the surface of each acupoint. The microcirculation sensitization rate of acupoints was calculated. Results: Compared with the control group, the dynamic changes in microcirculation at the following acupoints in the primary dysmenorrhea group were increased (P<0.05): conception vessel (Yinjiao[CV7], Qihai[CV6], Shimen[CV5], Guanyuan[CV4]); left thoroughfare vessel (left Huangshu[KI16], left Zhongzhu[KI15], left Siman[KI14], left Qixue[KI13], left Dahe[KI12], left Henggu[KI11]); left stomach meridian (left Tianshu[ST25], left Wailing[ST26], left Qichong[ST30]); left spleen meridian (left Daheng[SP15], left Fujie[SP14]); right thoroughfare vessel (right Huangshu[KI16], right Zhongzhu[KI15], right Siman[KI14], right Qixue[KI13], right Dahe[KI12], right Henggu[KI11]); right stomach meridian (right Wailing[ST26], right Daju[ST27], right Shuidao[ST28], right Guilai[ST29], right Qichong[ST30]); and right spleen meridian (right Fujie[SP14]). The area under the ROC curve of conception vessel (Yinjiao[CV7], Qihai[CV6], Shimen[CV5], Guanyuan[CV4]), thoroughfare vessel (right Siman[KI14], left Huangshu[KI16], right Qixue[KI13], right Zhongzhu[KI15], right Dahe[KI12], left Zhongzhu[KI15], left Siman[KI14], right Huangshu[KI16], left Qixue[KI13], right Henggu[KI11], left Henggu[KI11], left Dahe[KI12]); stomach meridian (left Tianshu[ST25], right Guilai[ST29], left Wailing[ST26], right Shuidao[ST28], right Daju[ST27], right Wailing[ST26], right Qichong[ST30], left Qichong[ST30]), and spleen meridian (left Daheng[SP15], left Fujie[SP14], right Fujie[SP14]) was 0.610-0.682 (P<0.05). Compared with the control group, the sensitization rate of some acupoints in the primary dysmenorrhea group increased (P<0.05). Conclusion With the onset of menstruation, the blood flow perfusion of some acupoints in the abdomen (thoroughfare, and conception vessels, and stomach and spleen meridians) of patients with primary dysmenorrhea and cold blood coagulation and blood stasis syndrome increased, and the status of acupoints changed from a resting state to an active state. These acupoints are sensitive in patients with primary dysmenorrhea and cold blood coagulation and blood stasis syndrome and have a certain diagnostic efficacy, providing a basis for further analyzing the efficacy and mechanism of acupuncture and moxibustion to treat primary dysmenorrhea with cold blood coagulation and blood stasis syndrome.

ObjectiveTo explore the main mechanism of self-precipitation formed during the decoction of Sinitang（SNT）， and to provide a research basis for exploring the differences in the toxic and effective components of this compound. MethodsThe average precipitation yields of SNT， Glycyrrhizae Radix et Rhizoma（GRR）-Aconiti Lateralis Radix Praeparata（ALRP） decoction（GF）， ALRP-Zingiberis Rhizoma（ZR） decoction（FJ）， GRR-ZR decoction（GJD）， ALRP decoction（FZ）， ZR decoction（GJ） and GRR decoction（GC） were determined. The four main self-precipitation samples of SNT， GF， FZ and GC were physically characterized by particle size， scanning electron microscopy（SEM）， pH， total dissolved solids（TDS）， conductivity， and Fourier transform infrared spectroscopy（FT-IR） analysis. The chemical compositions of SNT decoction and its different phases was identified by ultra-performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry（UPLC-Q-Exactive Orbitrap-MS） for SNT， SNT self-precipitation and SNT supernatant， and the contents of its main toxic and effective components were determined by high performance liquid chromatography（HPLC）. ResultsPrecipitation yield results of the 7 samples of SNT decoction and single decoction showed that SNT had the highest self-precipitation yield. The formation of SNT self-precipitation was mainly related to the reaction between ALRP and GRR components to form complexes， and FT-IR showed that GRR had the greatest influence on the formation of self-precipitation. A total of 110 components were identified in the SNT decoction， including 100 components in the SNT self-precipitation and 106 components in the SNT supernatant. And quantitative results of the main toxic and effective components revealed that the reaction between ALRP and GRR components formed complexes， resulting in the following content hierarchy for free components：SNT decoctionsupernatantself-precipitation， these components included free liquiritin， benzoylmesaconine， benzoylaconitine， benzoylhypacoitine， liquiritigenin， aconitine， hypoaconitine， isoliquiritigenin and ammonium glycyrrhizinate. ConclusionSNT exhibits spontaneous precipitation during compound decoction， with GRR exerting the greatest influence on its formation. This suggests GRR plays a significant role in the detoxification of SNT. The differences in the self-precipitated toxic-effective components of SNT compound decoction primarily manifest as changes in component content， reflecting the characteristics of SNT "deposition in vitro and sustained release in vivo" and the importance of "administered at draught" in the clinical application of SNT.

On this basis, a theoretical framework for factors influencing the use of intravenous therapy specialist nurses was constructed.Conclusions:This study constructs a theoretical framework for factors influencing the use of intravenous therapy specialist nurses. Managers can leverage this theoretical framework to develop targeted intervention strategies that enhance the effectiveness of intravenous therapy specialist nurses and optimize the allocation of nursing human resources.

Objective:To evaluate the efficacy and analyze the causes of complications of allogeneic decellularized dermal matrix grafts in the treatment of gingival recession using tunneling technology.Methods:Sixty patients with single or multiple gingival re-cession were randomly divided into an allogeneic decellularized matrix(ADM)group and a connective tissue(SCTG)group.Tunne-ling technique(TUN)were used in both groups to cover the root surface,and the gingival margin position,gingival margin morpholo-gy,and mucogingival junction position of the affected teeth at 1 week,3 weeks,3 months,and 6 months after surgery were observed.Check and record the gingival recession depth(RD)and mean root coverage(MRC)at the implant site before and 6 months after surgery.Record patient satisfaction at 3 weeks and 6 months after surgery.Results:Compared with the traditional SCTG group,the MRC of the ADM group was significantly lower before surgery and 6 months after surgery(P＜0.05).The satisfaction level of the ADM group was higher 3 weeks after surgery,with a significant difference compared to the SCTG group(P＜0.05).But 6 months after surgery,the satisfaction levels of the two groups tended to be consistent,with no significant difference.After TUN+ADM surgery,there was 1 case of abscess infection lesion,and another 3 cases showed local tissue necrosis at the gingival margin one week after surgery.After 3 months of treatment,the gingival color of these 4 patients was pink and tough texture,without swelling and bleeding.Conclusion:Although ADM is slightly inferior to SCTG in the treatment of gingival recession,it may be related to poor postoperative tissue healing complications.However,as long as it is handled properly,long-term follow-up observations have shown that gingival tissue can still achieve complete healing.TUN+ADM is a highly effective treatment for gingival recession and is suitable for further clinical application.

Objective:To explore the mechanism by which moxibustion improves cold-induced blood stasis pattern(CIBSP)and to uncover the biological basis underlying the correlation between the Conception Vessel(CV),Governor Vessel(GV),Thoroughfare Vessel(TV),and the uterus by investigating the effects of mild moxibustion on the hypothalamic-pituitary-ovary axis(HPOA)in CIBSP model rats.Methods:Forty-eight female Sprague-Dawley rats were divided into a blank group,a model group,a CV group,a GV group,a TV group,and a non-meridian non-point(NMNP)group according to the random number table method,with 8 rats in each group.Except for rats in the blank group,the other rats were subjected to an ice water bath plus epinephrine to prepare CIBSP models.Each intervention group was given mild moxibustion on the first day of modeling.Qihai(CV6),Guanyuan(CV4),and Zhongji(CV3)were selected in the CV group;Huangshu(KI16),Dahe(KI12),and Henggu(KI11)were selected in the TV group;Xuanshu(GV5),Mingmen(GV4),and Yaoyangguan(GV3)were selected in the GV group;three NMNP spots were selected in the NMNP group.Mild moxibustion was administered for 20 min each time,once a day,for 14 consecutive days.The symptom scores of CIBSP and uterine electromyogram were compared among groups;morphological changes in reproductive organs were observed by hematoxylin-eosin staining;enzyme-linked immunosorbent assay was used to detect serum reproductive hormones and neurotransmitters.The mRNA and protein expression levels of estrogen receptor(ER),follicle-stimulating hormone receptor(FSHR),and luteinizing hormone receptor(LHR)were detected by real-time quantitative polymerase chain reaction,immunohistochemistry,or Western blotting assays.Results:Compared to the blank group,the model group showed a significantly increased CIBSP symptom score,an amplified in vivo uterine myoelectric value;decreased ovarian follicles,thinner endometrial epithelium,and disordered structure with the pathological examination,decreased serum levels of reproductive hormones,6-keto-prostaglandin F1α(6-keto-PGF1α),and β-endorphin(β-EP),increased thromboxane B2(TXB2),5-hydroxytryptamine(5-HT),and substance P(SP),and decreased mRNA and protein expression of ovarian ER,FSHR,and LHR(P<0.05 or P<0.01).Compared to the model and NMNP groups,each point-intervention group showed a decreased CIBSP symptom score and uterine myoelectric value;increased ovarian follicles,thickened endometrium,increased glands,up-regulated serum reproductive hormones,6-keto-PGF1α,and β-EP,down-regulated serum TXB2,5-HT,and SP and increased mRNA and protein expression of ovarian ER,FSHR,and LHR(P<0.05 or P<0.01).Conclusion:Moxibustion at points from the CV,GV,and TV("three branches from one source")can improve the reproductive neuroendocrine function of CIBSP rats,and this effect may be mediated through the regulation of the HPOA.These detections suggest that the biological basis of point-uterus correlation may be based on HPOA regulation.

Objective:To develop a popular science educational product aimed at enhancing home-based self-management among peritoneal dialysis (PD) patients.Methods:A preliminary framework for popular science content on home-based self-management for PD patients was constructed based on an evidence summary.

A popular science video with a total duration of 5 minutes and 52 seconds was developed. A total of 158 PD patients rated the quality of the popular science educational product with an average score of (83.03±2.01) .Conclusions:The development method of the popular science educational product is scientifically sound, and the content is suitable for dissemination. It provides a practical reference for improving health literacy and self-management ability among home-based PD patients.

OBJECTIVE To explore the application of multiple hospital branches management mode in control of risk of hospital-acqueird infections in a general hospital so as to move forward the infection control threshold.METHODS The risk management closed loop,known as the infection index monitoring-risk assessment-risk re-sponse-effect evaluation-infection index monitoring,was adopted by People's Hospital of Ningxia Hui Autono-mous Region from Jan.to Jun.2024.The risk of infection at different levels of hospital zones,disciplines,clinical departments and risk indices was evaluated by risk matrix method.The correlation between the risk indices of clin-ical department and the risk scores was observed,and the dynamic monitoring was carried out for the change of risk of infection in the clinical departments.RESULTS The risk score was higher in the headquarter and Ningnan Branch than in the Xixia branch;the interquartile range(IQR)value from high to low was as follows:Xixia branch,hospital headquarter,Ningnan branch.The intensive care unit(ICU),nerve center and radiotherapy de-partment were the disciplines at extremely high risk of infection.The ICU,cardiac vascular surgery department and gastroenterology department of the hospital headquarters,the ICU,neurosurgery department and neurology department of Ningnan branch and the ICU and cardiac vascular surgery department of Xixia branch were the de-partments at extremely high risk of infection.The etiological submission rate before drug therapy,implementation of prevention measures for multidrug-resistant organisms(MDROs),cleaning and disinfection and missing report of hospital-acqueird infection cases were the major supervision indices.The absolute values of Spearman related co-efficient between clinical department risk scores and 4 indices-including the isolation rate of MDROs and the inci-dence of hospital-acqueird infection was greater than 0.5.CONCLUSION The risk management closed loop that is applied in the 'one hospital and multiple branches' medical institution may facilitate the dynamic monitoring,as-sessment and intervention the high-risk hospital branches,disciplines,departments and indices,and boost the ca-pability of risk management of infections in medical institutions.

Objective:To investigate the value of tumor volume to uterine volume ratio (N/U) combined with the expression of alpha-fetoprotein (AFP), sugar antigen 199 (CA199) and human epididymal secretory protein 4 (HE4) in evaluating the pathologic grade and prognosis of endometrial carcinoma (EC) .Methods:A total of 160 EC patients admitted to Linyi Central Hospital from Jan. 2021 to Dec. 2023 were divided into low-grade group and high-grade group according to FIGO grading method, and were divided into poor prognosis group and good prognosis group according to cancer death, recrudescence. The levels of N/U, AFP, CA199 and HE4 in patients with different pathologic grades and prognosis were compared. COX regression was used to analyze the influencing factors of EC adverse prognosis, ROC curve was used to analyze the value of N/U combined with serum AFP, CA199 and HE4 in predicting EC adverse prognosis, and a nomogram model was constructed.Results:Pathological examination of 160 EC patients showed that 12 cases were non-endometrioid adenocarcinoma, 148 cases were endometrioid adenocarcinoma, 41 cases were high-grade and 119 cases were low-grade.According to the follow-up, 94 of the 160 EC patients had good prognosis and 66 had poor prognosis. The levels of N/U, AFP, CA199 and HE4 in the poor prognosis group were higher than those in the good prognosis group ( P<0.05). COX regression analysis showed that high levels of N/U, AFP, CA199 and HE4 were all factors affecting the poor prognosis of EC patients ( P<0.05). The AUC value of combined detection of N/U, AFP, CA199 and HE4 in predicting adverse prognosis of EC patients was higher than that of single detection ( Z=3.140, 3.658, 4.277, 4.378, P<0.05) .The ROC curve AUC (95% CI) of the training set and the validation set were 0.84 (0.77-0.92) and 0.90 (0.81-0.98) respectively for the training set and the validation set to predict the adverse prognosis of EC patients. Calibration curve results showed that the calibration curve for EC patients predicted by the nomogram model was close to the ideal curve ( P=0.521, 0.743). The DCA curve shows that the probability threshold of the nomogram model has a higher positive net return at 20%~100%. Conclusion:The levels of N/U, AFP, CA199 and HE4 in EC patients are related to the pathologic grade, and the combined detection of these indicators can predict the poor prognosis of EC patients, and the nomogram model constructed based on these indicators has high predictive value.
