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.

Pinellia ternata， belonging to the Pinellia genus within the Araceae family， is a medicinal plant due to its tubers. There are severe issues with unclear germplasm and mixed varieties in its cultivation， necessitating urgent new variety protection efforts. The distinctness， uniformity， and stability （DUS） testing of the plant variety is the basis for protecting new plant varieties， and the DUS test guidelines are the technical basis for DUS testing. To develop the DUS test guidelines for P. ternata， agronomic traits of 229 germplasm of P. ternata were observed and measured during its two growth stages over the years， and each character was graded and described. A total of 38 traits were selected as the test traits of the DUS test guideline for P. ternata. There were three plant traits， 19 leaf traits， six flower traits， two fruit traits， two tuber traits， five bulbil traits， and one ploidy trait. These traits could be divided into 22 quality characters， 12 quantitative characters， and four pseudo-quantitative characters， as well as seven groups， including plants， leaves， flowers， fruit， tubers， bulbils， and ploidy. By searching for standard traits， 10 standard varieties were ultimately determined. Preparing these guidelines will have great significance for reviewing and protecting P. ternata varieties， safeguarding breeders' rights， and promoting the development of the P. ternata industry.

Objective: To investigate the protective effects and underlying mechanisms of sodium pyruvate (SP) on RBC storage lesions using an oxidative damage model. Methods: Six units of leukocyte-depleted suspended RBCs (discarded for non-infectious reasons within three days post-collection) were randomly assigned to four groups: negative control (NS), positive control (PS), experimental group 1 (SP1), and experimental group 2 (SP2). Oxidative stress was induced in the PS group by the addition of hydrogen peroxide (H O ), while SP1 and SP2 received SP supplementation at different concentrations (25 mM and 50 mM, respectively) in the presence of H O . After 1 hour of incubation, RBC morphology was assessed microscopically, and biochemical indicators including glutathione (GSH), malondialdehyde (MDA), methemoglobin (MetHb), adenosine triphosphate (ATP), and Na /K -ATPase activity were measured. Results: RBCs in the PS group exhibited pronounced morphological damage, including cell shrinkage and echinocyte formation, whereas both SP-treated groups showed significantly reduced structural injury. SP treatment led to elevated GSH levels and decreased concentrations of MDA and MetHb, suggesting attenuation of oxidative stress. Additionally, SP enhanced intracellular ATP levels and Na /K -ATPase activity, thereby contributing to membrane stability. Notably, the SP2 group (50 mM) demonstrated superior protective effects compared to SP1 (25 mM). Conclusion: Sodium pyruvate effectively attenuates oxidative storage lesions in RBCs, primarily through its antioxidant properties, energy metabolism supporting ability, and celluar membrane stabilizing function. These findings suggest SP as a promising additive for enhancing the quality and safety of stored RBCs.

Objective To explore the diagnostic value of endoscopic grading of gastric intestinal metaplasia (EGGIM) score under acetic acid-enhanced narrow band imaging (AA-NBI) observation mode for gastric intestinal metaplasia (GIM). Methods A total of 120 patients who underwent gastroscopy at Jinshan Hospital of Fudan University from February 2022 to February 2023 were selected. All patients underwent both white light and AA-NBI endoscopy, with photographic records of intestinal metaplasia in five areas: greater curvature of antrum, lesser curvature of antrum, greater curvature of corpus, lesser curvature of corpus and incisura. EGGIM score was performed: 0 for no intestinal metaplasia, 1 point for focal intestinal metaplasia (GIM area ratio≤30%), 2 points for extensive intestinal metaplasia (GIM area ratio＞30%), with a total score of 10 points. Targeted biopsies were performed on suspicious GIM lesions found during endoscopy. If no suspicious GIM lesions were observed, random biopsies were performed according to the updated Sydney system. The pathological histological examination results were staged based on the operative link on gastric intestinal metaplasia assessment (OLGIM) system. The diagnostic value of EGGIM score for OLGIM stage Ⅲ-Ⅳ patients was evaluated using receiver operating characteristic (ROC) curves. Results The sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) of AA-NBI in detecting GIM were 96.3%, 91.6%, 94.5%, 95.0%, and 93.6%, respectively. The area under the ROC curve for EGGIM diagnosing OLGIM stage Ⅲ-Ⅳ was 0.952 (95%CI 0.914-0.990). The optimal cut-off value for EGGIM was 5 points, with a sensitivity of 96.7% (95%CI 87.6%-99.4%) and specificity of 88.1% (95%CI 76.5%-94.7%). Conclusions EGGIM score (≥5 points) under AA-NBI mode has good diagnostic capability for patients with OLGIM stage Ⅲ-Ⅳ.

Objective To observe the clinical characteristics of patients with moderate hyponatremia in general surgery and analyze the efficacy.Methods Patients with moderate hyponatremia in general surgery were divided into control group(without supplemented concentrated sodium chloride injection)and treatment group(supplemented concentrated sodium chloride injection)according to the cohort method.The clinical characteristics of patients with moderate hyponatremia,such as gender distribution,age distribution,nutritional status,and primary disease were analyzed.Propensity score matching(PSM)was performed to balance confounding factors between the two groups,making their baseline conditions comparable and comparing the differences in clinical outcomes between the two groups.Results A total of 227 cases were included,including 82 in the control group and 145 in the treatment group.The predisposing factors of moderate hyponatremia in general surgery patients include male,elderly,malnutrition,parenteral nutrition,and malignant tumors.In addition,after PSM,there were 73 patients in each group of the control group and treatment group with moderate hyponatremia.The total effective rate of the control group was 80.82％,and correction of the hyponatremia takes time was(3.97±2.54)The total effective rate of the treatment group was 98.63％,and correction of the hyponatremia takes time was(3.54±1.90)d.The differences were statistically significant(all P＜0.05).Conclusion We should pay more attention to patients with moderate hyponatremia in general surgery,and be alert to the risk of severe hyponatremia.For patients with moderate hyponatremia,concentrated sodium chloride injection should be given to improve efficacy and prognosis.

Objective To explore the mediating effect of sleep duration on the relationship between qi stagnation constitution and anxiety/depression in junior high school students.Methods From March 20 to March 31,2020,a total of 10,325 students from 6 junior high schools in Henan,Liaoning,Shaanxi,Shandong,and Fujian provinces were sampled by cluster sampling.Firstly,the general conditions(age,gender,grade,hometown,whether they are an only child)and sleep duration were collected,and their qi stagnation constitution,depression and anxiety status were evaluated by using the Qi Stagnation Subscale in the"TCM Constitution Classification and Judgment Scale",the Patient Health Questionnaire(PHQ-9)and the Generalized Anxiety Disorder(GAD-7).Secondly,Spearman correlation analysis was used to explore the correlation between qi stagnation constitution,sleep duration,and anxiety/depression.Then,linear regression analysis and mediating effect test were used to explore the relationship between qi stagnation constitution and anxiety/depression in junior high school students,and the mediating effect of sleep duration was analyzed,and the results were verified.Results(ⅰ)The detection rate of anxiety in non-only children was higher than that of only children(x2=11.198,P=0.001);The detection rate of anxiety(x2=106.967,P＜0.001)or depression(x2=84.692,P＜0.001)was higher among senior students than those in lower grades,while those of girls with anxiety(x2=100.441,P＜0.001)or depression(x2=71.418,P＜0.001)were higher than those of boys.The detection rates of anxiety(x2=1 092.298,P＜0.001)and depression(x2=866.740,P＜0.001)in qi stagnation constitution students were higher than those of non-qi stagnation constitution students,and the detection rates of anxiety(x2=1 076.716,P＜0.001)and depression(x2=1 099.725,P＜0.001)in students whose sleep duration less than 8 h were higher than those of whose sleep duration more than 8 h,and the shorter the sleep duration,the higher the detection rate.(ⅱ)Qi stagnation constitution positively predicted anxiety/depression(β=0.679,P＜0.001;β=0.718,P＜0.001),and sleep duration had a negative predictive effect on anxiety/depression(β=-0.403,P＜0.001;β=-0.439,P＜0.001).(ⅲ)Sleep duration played a partial mediating role in the relationship between qi stagnation constitution and anxiety/depression in junior high school students,and the mediating effect accounted for 13.40％and 13.79％of the total effect,respectively.Conclusion Although qi stagnation constitution mainly affects anxiety/depression through direct effect,it can still be partially indirectly realized through the mediating variable of sleep duration,that is,the shorter the sleep duration,the higher the risk of anxiety/depression in junior high school students.Therefore,the mental health problems of junior high school students can be prevented and improved by regulating qi stagnation constitution and ensuring adequate sleep duration.

Objective:To investigate the current status of endoscopic treatment for gastroesophageal varices in portal hypertension in China, and to provide supporting data and reference for the development of endoscopic treatment.Methods:In this study, initiated by the Liver Health Consortium in China (CHESS), a questionnaire was designed and distributed online to investigate the basic condition of endoscopic treatment for gastroesophageal varices in portal hypertension in 2022 in China. Questions included annual number and indication of endoscopic procedures, adherence to guideline for preventing esophagogastric variceal bleeding (EGVB), management and timing of emergent EGVB, management of gastric and isolated varices, and improvement of endoscopic treatment. Proportions of hospitals concerning therapeutic choices to all participant hospitals were calculated. Guideline adherence between secondary and tertiary hospitals were compared by using Chi-square test.Results:A total of 836 hospitals from 31 provinces (anotomous regions and municipalities) participated in the survey. According to the survey, the control of acute EGVB (49.3%, 412/836) and the prevention of recurrent bleeding (38.3%, 320/836) were major indications of endoscopic treatment. For primary [non-selective β-blocker (NSBB) or endoscopic therapies] and secondary prophylaxis (NSBB and endoscopic therapies) of EGVB, adherence to domestic guideline was 72.5% (606/836) and 39.2% (328/836), respectively. There were significant differences in the adherence between secondary and tertiary hospitals in primary prophylaxis of EGVB [71.0% (495/697) VS 79.9% (111/139), χ2=4.11, P=0.033] and secondary prophylaxis of EGVB [41.6% (290/697) VS 27.3% (38/139), χ2=9.31, P=0.002]. A total of 78.2% (654/836) hospitals preferred endoscopic therapies treating acute EGVB, and endoscopic therapy was more likely to be the first choice for treating acute EGVB in tertiary hospitals (82.6%, 576/697) than secondary hospitals [56.1% (78/139), χ2=46.33, P<0.001]. The optimal timing was usually within 12 hours (48.5%, 317/654) and 12-24 hours (36.9%, 241/654) after the bleeding. Regarding the management of gastroesophageal varices type 2 and isolated gastric varices type 1, most hospitals used cyanoacrylate injection in combination with sclerotherapy [48.2% (403/836) and 29.9% (250/836), respectively], but substantial proportions of hospitals preferred clip-assisted therapies [12.4% (104/836) and 26.4% (221/836), respectively]. Improving the skills of endoscopic doctors (84.2%, 704/836), and enhancing the precision of pre-procedure evaluation and quality of multidisciplinary team (78.9%, 660/836) were considered urgent needs in the development of endoscopic treatment. Conclusion:A variety of endoscopic treatments for gastroesophageal varices in portal hypertension are implemented nationwide. Participant hospitals are active to perform emergent endoscopy for acute EGVB, but are inadequate in following recommendations regarding primary and secondary prophylaxis of EGVB. Moreover, the selection of endoscopic procedures for gastric varices differs greatly among hospitals.

OBJECTIVE: To determine the role of Tripterygium wilfordii multiglycoside (TGW) in the treatment of psoriatic dermatitis from a cellular immunological perspective. METHODS: Mouse models of psoriatic dermatitis were established by imiquimod (IMQ). Twelve male BALB/c mice were assigned to IMQ or IMQ₊TGW groups according to a random number table. Histopathological changes in vivo were assessed by hematoxylin and eosin staining. Ratios of immune cells and cytokines in mice, as well as PAM212 cell proliferation in vitro were assessed by flow cytometry. Pro-inflammatory cytokine expression was determined using reverse transcription quantitative polymerase chain reaction. RESULTS: TGW significantly ameliorated the severity of IMQ-induced psoriasis-like mouse skin lesions and restrained the activation of CD45⁺ cells, neutrophils and T lymphocytes (all P<0.01). Moreover, TGW significantly attenuated keratinocytes (KCs) proliferation and downregulated the mRNA levels of inflammatory cytokines including interleukin (IL)-17A, IL-23, tumor necrosis factor α, and chemokine (C-X-C motif) ligand 1 (P<0.01 or P<0.05). Furthermore, it reduced the number of γ δ T17 cells in skin lesion of mice and draining lymph nodes (P<0.01). CONCLUSIONS TGW improved psoriasis-like inflammation by inhibiting KCs proliferation, as well as the associated immune cells and cytokine expression. It inhibited IL-17 secretion from γ δ T cells, which improved the immune-inflammatory microenvironment of psoriasis.

Liver regeneration following injury aids the restoration of liver mass and the recovery of liver function. In the present study we investigated the contribution of megakaryocytic leukemia 1 (MKL1), a transcriptional modulator, to liver regeneration. We report that both MKL1 expression and its nuclear translocation correlated with hepatocyte proliferation in cell and animal models of liver regeneration and in liver failure patients. Mice with MKL1 deletion exhibited defective regenerative response in the liver. Transcriptomic analysis revealed that MKL1 interacted with E2F1 to program pro-regenerative transcription. MAPKAPK2 mediated phosphorylation primed MKL1 for its interaction with E2F1. Of interest, phospholipase d2 promoted MKL1 nuclear accumulation and liver regeneration by catalyzing production of phosphatidic acid (PA). PA administration stimulated hepatocyte proliferation and enhanced survival in a MKL1-dependent manner in a pre-clinical model of liver failure. Finally, PA levels was detected to be positively correlated with expression of pro-regenerative genes and inversely correlated with liver injury in liver failure patients. In conclusion, our data reveal a novel mechanism whereby MKL1 contributes to liver regeneration. Screening for small-molecule compounds boosting MKL1 activity may be considered as a reasonable approach to treat acute liver failure.
