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.

Objective To examine the independent and combined impact of pre-pregnancy overweight or obesity(OWOB)and gestational diabetes mellitus(GDM)on infant body mass index-for-age z score(BMIZ)growth trajectories during the first year of life.Methods A retrospective cohort study was conducted using data from Zhuhai Center for Maternal and Child Health Care between June 2022 and October 2024.A total of 4481 mother-infant pairs meeting the inclusion criteria were enrolled.Pre-pregnancy body mass index(BMI),second-trimester oral glucose tolerance test(OGTT)results,and longitudinal growth data of offspring(including weight and length at birth and at 1,3,6,9,and 12 months of age)were collected.A latent class growth mod-el was used to identify distinct BMIZ trajectories,and multinomial logistic regression was applied to examine the independent and combined effects of maternal OWOB and GDM on offspring BMIZ trajectories.Results Three distinct BMIZ trajectories were identified:appropriate-stable,rapid growth,and catch-up growth.Compared with offspring of mothers with normal pre-pregnancy BMI and without GDM,those born to mothers with both pre-pregnancy OWOB and GDM had a significantly higher risk of following a catch-up growth trajectory(OR=1.74,95％CI:1.13-2.68)or a rapid growth trajectory(OR=1.33,95％CI:1.03-1.71).However,no significant associations were observed in the offspring of mothers with OWOB alone or GDM a-lone(all P＞0.05).Additionally,when comparing offspring of mothers with both OWOB and GDM to those offspring of moth-ers with OWOB alone or GDM alone,no significant differences in BMIZ trajectory risk were found(all P＞0.05).Conclusion Pre-pregnancy OWOB combined with GDM,but not pre-pregnancy OWOB or GDM alone,increases risk of rapid growth and catch-up BMIZ trajectory of offspring.These findings highlight the importance of optimizing maternal pre-pregnancy weight and maintaining appropriate glycemic control during pregnancy promotes healthier infant growth patterns.

Objective We aimed to observe the differences in the effects of different acupuncture technique on the endometrium of mice with simple endometrial hyperplasia model and to explore the potential mechanisms. Methods According to the random number tables,32 female C57BL/6J mice were divided into a blank control group,a model group,a quick needle group and a retaining needle group,with 8 mice in each group. A mouse model of simple endometrial hyperplasia was established using bilateral ovariectomy combined with estrogen loading. In the quick needle group,mice were punctured at the bilateral for "Yinbai"(SP1) points and withdrawn immediately,with the treatmeat performed once every other day for a total of 12 times. In the retaining needle group,mice were punctured at the bilateral "Yinbai"(SP1) points and the needles were retained for 15 min each time,with the treatment also performed once every other day for a total of 12 times. After the intervention,samples were collected. HE staining was used to observe morphological changes in the mouse uterine tissue;ELISA was used to detect serum estradiol level;flow cytometry was used to detect the ratio of M1 and M2 macrophages(M1/M2) and immunohistochemical method was used to measure the expression of CD86 and CD206 in uterine tissue;and Western blotting was used to detect the expression of interleukin-13 (IL-13) and interferon-γ(IFN-γ) in uterine tissue. Results The endometrium of mice in the model group showed simple hyperplasia. Compared with the blank control group,the endometrium of the model group was thickened (P<0.01);the level of estradiol in the serum was increased (P<0.01);M1/M2 in uterine tissues was decreased (P<0.01),the expression of CD86 was decreased (P<0.01),and the positive expression of CD206 was increased (P<0.01);and the level of IFN-γ protein expression in uterine tissues was decreased (P<0.01),and the expression of IL-13 protein was increased (P<0.01). Compared with the model group,the endometrial thicknesses of the quick needle group and the retaining needle group were reduced (P<0.05),the levels of estradiol in serum were reduced (P<0.05),M1/M2 in uterine tissues increased (P<0.01),and the reduction of CD206 positive expression,and IL-13 protein expression reduced (P<0.01);the level of CD86 positive expression,IFN-γ protein expression increased (P<0.01). Compared with the quick needle group,IL-13 protein expression increased in the retaining needle group (P<0.01).Conclusion Both quick needle and retaining needle may be through the regulation of the expression of IFN-γ and IL-13,thus prompting the polarization of macrophages from M2 to M1 type,inhibiting the pro-cell proliferative ability and tissue repair ability of M2 type macrophages,thus reducing the degree of endometrial hyperplasia,and the quick needle group was superior to the retaining needle group in regulating the expression of IL-13.

OBJECTIVE To compare the efficacy of the novel Huoxue plaster and the original powder in the treatment of chronic soft tissue injury, and to provide experimental basis for the development and clinical application of hospital preparations. METHODS According to the different drug administration, mice were assigned to the blank group, the matrix group, the positive control group(voltaren group), the original powder raw product group, the original powder product group and the novel plaster group respectively. The writhing inhibition rate, licking time, analgesic rate and pain threshold were measured by the writhing test, formaldehyde pain test, electrical stimulation test and hot plate test. The purpose of these was to assess disparities in the drugs for analgesic purposes. The mice ear swelling test and capillary permeability test were used to determine the swelling degree, swelling inhibition rate and exudation inhibition rate to compare the differences in anti-inflammatory effects. A rat model of chronic soft tissue injury was established. The changes of calf circumference, soft tissue injury appearance score, hemorheology and histopathological observation and inflammatory factor content were compared before and after the reform of prescription and dosage form. RESULTS The novel Huoxue plaster had a significant inhibitory effect on the inflammatory pain induced by acetic acid and formaldehyde in mice, and there was no significant difference compared with the original powder. The analgesic effect of 60 min after administration was better than that of 90 min and 120 min after administration, and there was no significant difference compared with the original powder. The novel Huoxue plaster and the original powder had no significant effect on hot plate pain threshold. The novel Huoxue plaster had a significant anti-inflammatory effect, which could reduce the degree of ear swelling induced by xylene and reduce the inflammatory exudation of capillaries induced by acetic acid, and there was no significant difference compared with the original powder. The novel Huoxue plaster could significantly reduce the circumference and injury symptom index of the swollen leg in rats with chronic soft tissue injury, improve blood circulation and histomorphology, and significantly reduce the contents of PGE2, TNF-α and IL-1β in the injured soft tissue, and there was no significant difference compared with the original powder. CONCLUSION The novel Huoxue plaster has significant analgesic and anti-inflammatory effects, and can be used to treat chronic soft tissue injury. The efficacy of the novel Huoxue plaster is basically the same as that of the original powder.

【Objective】 To investigate the imaging features of weak response after anti-vascular endothelial growth factor (VEGF) treatment for refractory diabetic macular edema (DME) with vesicles. 【Methods】 We made a retrospective analysis of the clinical data of 120 patients with DME (120 eyes) who received anti-VEGF therapy in Ophthalmology Department of The Second Affiliated Hospital of Xi’an Jiaotong University from March 2018 to September 2019 and the same anti-VEGF medicine with the therapeutic regimen of 3+PRN. Of the 50 patients with cystoid macular edema (CME), 40 of them had a significant response and 10 had a weak response. The characteristics of optical coherence tomography (OCT) and fundus fluorescein angiography (FFA) for the patients with weak response after anti-VEGF therapy were comparatively analyzed. 【Results】 Eyes with vesicular DME that responded weakly to anti-VEGF treatment had similar imaging characteristics. The OCT images showed impurity-independent vesicles located in the inner layer of the retina. Compared with the obvious response group, the reflection signal of the vesicle area was significantly enhanced. In early images of FFA, micro-angiomas related to vesicle formation were seen in both groups. However, in the late FFA image, the leakage intensity of vesicles in the weak response group was significantly lower than that in the obvious response group. 【Conclusion】 Vesicular DME with poor anti-VEGF treatment has the characteristics of high reflection in OCT and weak fluorescence leakage in FFA. This study is helpful for preoperative evaluation of anti-VEGF treatment.

Objective To compare the prognosis of different surgical procedures and to find the relatively safe and effective treatment for severe jejunoileal atresia(sJA).Method From January 2007 to June 2018,children with sJA receiving different surgical procedures in our hospital were retrospectively reviewed.Their clinical data were analyzed,including the survival rate,complication rate,unplanned re-operation rate and postoperative nutritional status.Result A total of 130 patients were enrolled in this study.According to the different types of surgical procedures,the patients were assigned into primary anastomosis group (58 cases,44.6％),Mikulicz double barrel ileostomy group (17 cases,13.1％) and Bishop-Koop anastomosis group (55 cases,42.3％).The overall mortality rate was 6.2％ (8/130).No significant differences existed in mortality rates among the three groups (P＞0.05).The incidences of gastrointestinal complications in primary anastomosis group (70.6％,12/17) and Mikulicz group (70.6％,12/17) were both higher Bishop-Koop group (34.5％,19/55),the differences were statistically significant (P＜0.05).The unplanned re-operation rates were 34.5％ (20/58) in the primary anastomosis group and 17.6％ (3/17) in the Mikulicz group,both higher than the Bishop-Koop group (3.6％,2/55),the differences were also statistically significant (P＜0.05).Multivariate analysis showed that the risk of complications in the primary anastomosis group (OR=3.434,95％CI 1.392～8.471) and Mikulicz group (OR=5.933,95％CI 1.467～23.991) were higher than the Bishop-Koop group.The risk of unplanned re-operation in the primary anastomosis group was 12.422 times as the Bishop-Koop group (95％CI 2.535～60.877).No significant differences existed between the Mikulicz group and the Bishop-Koop group in the risk of unplanned re-operation (P＞0.05).The weight for age (Z-score) in the Bishop-Koop group (-1.4,95％CI-2.0～-0.8) at the stoma closure time was better than the Mikulicz group (-3.2,95％CI-4.4～-2.0),the difference was statistically significant (P＜0.01).Conclusion Bishop-Koop anastomosis has lower complication rate and lower unplanned re-operation rate in the treatment of sJA.The nutritional status of children who received Bishop-Koop anastomosis is better than Mikulicz double barrel ileostomy at the stoma closure time.Bishop-Koop anastomosis is relatively safe and effective for sJA patients.

Objective: To analysis the risk factors of postoperative bleeding of endoscopic submucosal dissection (ESD) for early gastrointestinal cancer. Methods: A retrospective study was performed on the data of 430 patients (449 lesions) with early gastrointestinal cancer undergoing ESD in Fujian Provincial Hospital Digestive Endoscopic Center from June 2008 to February 2015 and in Fujian Provincial Hospital South Branch Digestive Endoscopic Center from May 2015 to April 2018. Patients with postoperative bleeding were compared with those without postoperative bleeding on the basis of general conditions, endoscopic performance, postoperative pathology and so on to analysis the risk factors for postoperative bleeding of ESD. Results: Among the 430 cases (449 lesions)of early gastrointestinal cancer undergoing ESD, 16 cases (3.7%) had postoperative bleeding. According to whether the occurrence of postoperative hemorrhage, patients were divided into bleeding group (n=16) and not bleeding group (n=433). Univariate analysis suggested that whether had hypertension was statistically significant between the two groups (χ²=4.793, P=0.029), while patients age (t=0.465, P=0.642), gender (χ²=0.035, P=0.642), whether to have diabetes (χ²=0.647, P=0.421), whether to have coronary heart disease (P=1.000), lesion size (t=1.598, P=0.111), whether two or more lesions (P=1.000), lesion site (χ²=6.183, P=0.289), operation time (t=1.335, P=0.201), pathological grading (χ²=0.687, P=0.709), and lesion infiltration depth (χ²=0.134, P=0.714) were not statistically significant between the two groups. Logistic regression analysis showed that hypertension (OR=3.358, 95%CI: 1.227-9.186, P=0.018) was an independent risk factor of bleeding after ESD for early gastrointestinal cancer. Conclusion Hypertension is closely related to postoperative bleeding following ESD for early gastrointestinal cancer.Patients with hypertension are at a greater risk of bleeding after ESD.
