ObjectiveTo observe the effect of Huayu Mingmu prescription on retinal angiogenesis and phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR)-hypoxia inducible factor-1α/vascular endothelial growth factor A (HIF-1α/VEGFA) signaling pathway in diabetic retinopathy (DR) rats. MethodsSixty-four SPF-grade male SD rats were used in the study. Eleven rats were randomly selected as the normal group, while the remaining 53 rats were fed a high-sugar, high-fat diet combined with low-dose streptozotocin (STZ) intraperitoneal injection to establish a type 2 diabetes mellitus (T2DM) rat model. DR model evaluation was performed after 12 weeks of diabetes. The rats were then divided into model, low-dose, medium-dose, and high-dose groups of Huayu Mingmu prescription (9.29, 18.57, 37.14 g·kg-1), and a calcium dobesilate group (0.16 g·kg-1), with 10 rats in each group. The rats were orally administered the corresponding doses of Huayu Mingmu prescription and calcium dobesilate. The normal and model groups received equal volumes of physiological saline via gavage for 8 consecutive weeks. Retinal vascular changes were observed through fundus photography, and pathological changes in retinal tissue were evaluated using hematoxylin-eosin (HE) staining. Retinal microvascular pathological changes were examined through retinal vascular network preparation and periodic acid-Schiff (PAS) staining. Immunofluorescence (IF) was used to detect the expression of VEGFA and angiopoietin-2 (Ang-2) in retinal tissue. Western blot was employed to detect the protein expression of PI3K, Akt, mTOR, HIF-1α, VEGFA, and VEGFR2 in retinal tissue. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to assess the mRNA expression of PI3K, Akt, mTOR, HIF-1α, VEGFA, and VEGFR2 in retinal tissue. ResultsCompared with the normal group, the model group exhibited significant pathological changes in retinal tissue, including the appearance of acellular capillaries, as well as significant endothelial cell (E) proliferation and pericyte (P) loss (P<0.01). The E/P was significantly elevated (P<0.01). Protein and mRNA expression levels of PI3K, Akt, mTOR, HIF-1α, VEGFA, and VEGFR2 in retinal tissue were significantly increased (P<0.01), and the expression of Ang-2 protein was significantly elevated (P<0.01). In contrast, retinal tissue in the treatment groups showed alleviated pathological changes, with reduced endothelial cell proliferation and pericyte loss (P<0.05, P<0.01). Among the treatment groups, the high-dose Huayu Mingmu prescription and the calcium dobesilate group exhibited a decreased E/P (P<0.01). Protein and mRNA expression levels of PI3K, Akt, mTOR, HIF-1α, VEGFA, and VEGFR2 in retinal tissue were significantly reduced (P<0.05, P<0.01), and the expression of Ang-2 protein was significantly decreased (P<0.01). ConclusionHuayu Mingmu prescription can intervene in retinal neovascularization in DR rats, delay the progression of DR, and its mechanism may be related to antagonizing the PI3K/Akt/mTOR-HIF-1α/VEGFA signaling pathway.

Objective:
To explore the association between parent-child connectedness and romantic relationships of secondary vocational school students and the moderating effect of peers romantic behavior, providing scientific basis for family and school health education.
Methods:
From March to April 2021,2 426 students from six secondary vocational and technical schools in Shanghai and Shaanxi Province were selected to conduct the survey by combining convenience sampling and cluster sampling.Electronic questionnaires were used to collect data on students family characteristics,oneself and peer romantic behaviors, and parent-child bonding. The t-test was employed for inter group comparisons, and binary Logistic regression analysis was conducted to examine the relationship between parent-child bonding levels, peer romantic behavior, and the romantic behavior of secondary vocational students.
Results:
The mother-child connection (2.63±0.77) was higher than that of father-child connection (2.48±0.78), with statistically significant difference ( t =6.83, P <0.01). Multivariable Logistic regression showed that overall father-child connectedness was negatively associated with students romantic relationships( OR =0.86,95% CI =0.76-0.97, P =0.02)and was only associated to girls romantic relationships when stratified by gender( OR =0.79,95% CI =0.66-0.93, P =0.01). Peers romantic relationships were positively associated with students romantic relationships ( OR =3.19-5.12, all P <0.01), and there was a moderating effect of the association between maternal connectedness and boys romantic relationships ( OR =1.67, 95% CI =1.05-2.66, P =0.03). Among boys without romantic peers, mother-child connectedness was negatively associated with their romantic relationships ( OR = 0.60 , 95% CI =0.36-0.99, P <0.05). In the total sample of Shanghai and girls of Shaanxi, father-child connectedness was negatively correlated with the romantic relationships of secondary vocational school students ( OR =0.84,0.65,95% CI =0.71-1.00,0.50-0.85,both P <0.05). Peer romantic relationships exhibited a negative moderating effect on the influence of mother-child connectedness on the romantic relationships of males in Shanghai ( OR =1.91, 95% CI =1.03-3.57, P <0.05).
Conclusions
The father-daughter connectedness is negatively correlated with girls romantic behavior, and peer romantic behavior weakens the correlation between mother-child connectedness and boys romantic behavior. Efforts should be made to enhance the parent-child connectedness of secondary vocational students and their ability to cope with peer influence, providing proper guidance for adolescents heterosexual interactions.

OBJECTIVE:Some studies have shown that kinesio taping has positive effects in elevating muscle strength,improving joint stability and reducing pain and oedema in patients after anterior cruciate ligament reconstruction.However,existing studies have divergent results on the clinical efficacy of kinesio taping.In this study,a meta-analysis was conducted to systematically evaluate the effect of kinesio taping in postoperative rehabilitation period following anterior cruciate ligament reconstruction. METHODS:Randomized controlled trials about the effects of kinesio taping on anterior cruciate ligament reconstruction were electronically searched in PubMed,Web of Science,Embase,The Cochrane Library,EBSCO,CNKI,WanFang,and VIP databases,from database inception to December 06,2022.The outcome measures included six continuous variables:quadriceps strength,hamstring strength,knee swelling,knee range of motion,Lysholm knee function score,and Visual Analogue Scale score.EndNote X9.1 was used to screen the literature.The Cochrane Risk Bias Assessment Tool and Jadad Scale were used to evaluate the quality of the included literature.RevMan 5.3 software was used for Meta-analysis. RESULTS:A total of 6 randomized controlled trials involving 252 patients undergoing anterior cruciate ligament reconstruction were finally included.There were 126 cases in control group and 126 in kinesio taping group.The results of Meta-analysis showed that compared with the control group,kinesio taping significantly improved hamstring strength[standardized mean difference(SMD)=0.68,95%confidence interval(CI):0.12 to 1.23,P=0.02)and reduced Visual Analogue Scale score[mean difference(MD)=-0.56,95%CI:-1.04 to-0.08,P=0.02).However,for quadriceps strength,knee swelling,knee range of motion,and Lysholm knee function score,kinesio taping did not show significant difference from the control group(P>0.05). CONCLUSION:Kinesio taping may help to improve hamstring strength and reduce pain in patients after anterior cruciate ligament reconstruction.However,it cannot significantly improve quadriceps strength,knee swelling,knee range of motion,and functional scores.

Talents are the main force for the development of traditional Chinese medicine(TCM), and the construction of TCM talents and the reformation of talent evaluation system are essential to promote the inheritance and innovation of TCM. At present, we are still exploring and developing in the fields of the formulation, implementation and evaluation indicators of TCM talent evaluation system. However, there are shortcomings and difficulties. For instance, insufficient stratification in the evaluation, excessive emphasis on the quantity of achievements, neglecting the quality of the achievements and the actual contribution, imperfect assessment indicators, and the weak characteristics of TCM. Therefore, national ministries and commissions have jointly issued a document requesting to break the four only and set a new standard, in order to promote the construction of a scientific and technological talent evaluation system oriented by innovation value, ability and contribution. For the evaluation of TCM clinical talents, China Association for Science and Technology commissioned China Association of Chinese Medicine to build the China Clinical Cases Library of TCM(CCCL-TCM), which aims at collecting the most authoritative and representative TCM clinical cases and exploring the advantages of applying clinical cases as masterpiece of achievement in TCM clinical talents evaluation. CCCL-TCM can promote the construction of a talent evaluation system that is more in line with the development characteristics of TCM industry, and to carry out relevant pilot in TCM colleges and institutions across the country in order to promote the reformation of TCM talent evaluation system.

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 explore the surgical technique and results of three-dimensional aortic valve anatomic repair for bicuspid aortic valve (BAV) with aortic regurgitation (AR).Methods:This is a retrospective case series study. From August 2021 to December 2023, 130 consecutive patients with BAV-AR underwent aortic valve anatomic repair at the Department of Cardiothoracic Surgery, Zhongshan Hospital, Fudan University,and the data were retrospectively analyzed. There were 115 males and 15 females, aged (38.6±11.7) years (range: 15 to 67 years). All patients received modified aortic root reconstruction, to do three-dimensional root remodeling, including the basal ring, sinus of Valsalva and sino-tubular junction simultaneously. Perioperative and follow-up data were collected and analyzed. Comparisons between groups were performed using independent samples t-test, Wilcoxon paired signed-rank test, or χ2 test. Results:No patient transferred to valve replacement during the operation. The cardiopulmonary bypass time ( M(IQR)) was 109(34) minutes (range:67 to 247 minutes), and the aortic cross-clamp time was 76(26) minutes (range: 32 to 158 minutes). Preoperative transesophageal echocardiography showed 123 patients (94.6%) presented with moderate or severe regurgitation. Immediately postoperative transesophageal echocardiography showed no regurgitation in 22 patients (16.9%), trace regurgitation in 81 patients (62.3%) and mild regurgitation in 27 patients (20.8%). Follow up was completed in all patients, with a follow-up of 5.5(9.4) months (range: 0.1 to 27.6 months). No mortality was observed during follow-up. Echocardiography was obtained in 112 patients at the latest follow-up, including no regurgitation in 4 patients (3.6%), trace regurgitation in 58 patients (51.8%), mild regurgitation in 45 patients (40.2%), moderate regurgitation in 4 patients (3.6%), and severe regurgitation in 1 patient (0.9%). Conclusion:For patients with BAV-AR who have good valve quality and no severe aortic sinus dilation, the recent outcomes of three-dimensional anatomical repair technique, focusing on overall remodeling of the aortic root, are satisfactory.
