Dry eye disease(DED)is a common ocular surface disorder worldwide, primarily characterized by a loss of homeostasis of the tear film, and frequently associated with meibomian gland dysfunction(MGD), decreased tear film stability, ocular discomfort, and visual impairment. In recent years, factors such as the widespread use of digital devices,the aging population, and environmental changes have contributed to a significant increase in its global prevalence, making it a major public health concern. Red light therapy(RLT), also known as low-level laser therapy(LLLT)or photobiomodulation(PBM), is a non-invasive treatment that utilizes low-energy red or near-infrared light to irradiate tissues. It exerts photobiomodulatory effects to promote cellular repair and functional recovery. This therapy has demonstrated considerable potential in treating various ocular conditions. Its broader clinical application could improve therapeutic outcomes, alleviate patient discomfort and financial burden, and reduce the consumption of healthcare resources, thereby yielding significant socio-economic benefits. This paper systematically reviews the multifaceted mechanisms and application prospects of RLT in managing DED, including its anti-inflammatory effects, improvement of meibomian gland function, promotion of conjunctival goblet cell repair, and alleviation of visual fatigue, aiming to provide a theoretical foundation and practical reference for its clinical adoption.

Esophagogastric variceal bleeding is a common complication and the leading cause of death in advanced liver cirrhosis， and endoscopic variceal ligation （EVL） and endoscopic cyanoacrylate injection （ECI） are commonly used treatment strategies. Thrombocytopenia is one of the most common hematological complications in liver cirrhosis， and patients with severe thrombocytopenia have the potential risk of bleeding， which may affect treatment decision-making by clinicians and endoscopists. This article reviews the evolution of guidelines and clinical research advances regarding EVL/ECI in China and globally， in order to provide a basis for decision making among clinicians.

The randomized controlled trials (RCTs) regarding acupuncture direction published from January 1st, 2013, to November 7th, 2023 were searched in China National Knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform, and VIP Chinese Journal Database. As a result, 21 RCTs were included. The problems identified included conceptual misunderstandings regarding acupuncture direction, incomplete selection strategies, confounding research factors, and inaccuracies in reporting. Based on the findings, four strategic approaches for enhancing therapeutic efficacy through acupuncture direction were summarized: aligning needle direction with the meridian pathway, directing the needle toward the lesion site, orienting the needle toward adjacent acupoints, and targeting special anatomical structures. Two additional strategies were proposed for optimizing the procedure: simplifying acupuncture operations and directing the needle toward safe anatomical sites. Recommendations were made to improve the rationality of research factor settings and the completeness of acupuncture operation reporting. Furthermore, three methods for reporting acupuncture direction were discussed: reporting the tip-pointed position, reporting the insertion angle and orientation, and reporting azimuth and polar angles, aiming to promote greater standardization and completeness in acupuncture practice and reporting.

Objective: To explore the mechanism of cistanche deserticola(meat cistanche) in treating Alzheimer′s disease(AD) through network pharmacology, molecular docking, and animal experiments. Methods : Effective components of meat cistanche were mined from the TCMSP database, and AD-related targets were filtered using the SwissTargetPrediction, DisGeNET, and GeneCards databases. The intersection of these targets was analyzed using protein-protein interaction(PPI) networks. Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analyses were conducted via the Metascape database. Molecular docking of meat cistanche′s active components with core targets was performed using AutoDock Vina. Based on network pharmacology predictions, an AD model was established using 8-month-old SAMP8 mice, with Morris water maze tests assessing learning and cognitive functions, Nissl staining observing hippocampal neuron morphology, and enzyme-linked immunosorbent assays and Western blotting detecting the expression levels of cAMP signaling pathway-related proteins in hippocampal tissues. Results : Network pharmacology analysis predicted that meat cistanche might act on 74 AD targets through 8 active components. Molecular docking showed high affinity of active components like acteoside with core targets such as ESR1, BDNF, MAPK1, and APP. KEGG analysis indicated involvement in pathways related to cancer, cAMP signaling, and AD. Animal experiments demonstrated that meat cistanche effectively improved learning and cognitive impairments in AD mice and alleviated hippocampal neuron damage. ELISA and Western blotting results indicated that meat cistanche significantly increased the expression levels of cAMP, PKA, P-CREB in the cAMP pathway and promoted the expression of downstream neurotrophic factor BDNF. Conclusion Meat cistanche can improve learning and cognitive disorders in AD model mice and may exert therapeutic effects on AD by up-regulating the cAMP signaling pathway and the expression of downstream BDNF protein targets, thereby improving hippocampal neuron injury.

Objective To investigate the differences and the immunocompatibility of wild-type (WT), four-gene modified (TKO/hCD55) and six-gene modified (TKO/hCD55/hCD46/hTBM) pig erythrocytes with human serum. Methods The blood samples were collected from 20 volunteers with different blood groups. WT, TKO/hCD55, TKO/hCD55/hCD46/hTBM pig erythrocytes, ABO-compatible (ABO-C) and ABO-incompatible (ABO-I) human erythrocytes were exposed to human serum of different blood groups, respectively. The blood agglutination and antigen-antibody binding levels (IgG, IgM) and complement-dependent cytotoxicity were detected. The immunocompatibility of two types of genetically modified pig erythrocytes with human serum was evaluated. Results No significant blood agglutination was observed in the ABO-C group. The blood agglutination levels in the WT and ABO-I groups were higher than those in the TKO/hCD55 and TKO/hCD55/hCD46/hTBM groups (all P<0.001). The level of erythrocyte lysis in the WT group was higher than those in the ABO-C, TKO/hCD55 and TKO/hCD55/hCD46/hTBM groups. The level of erythrocyte lysis in the ABO-I group was higher than those in the TKO/hCD55 and TKO/hCD55/hCD46/hTBM groups (both P<0.01). The pig erythrocyte binding level with IgM and IgG in the TKO/hCD55 group was lower than those in the WT and ABO-I groups. The pig erythrocyte binding level with IgG and IgM in the TKO/hCD55/hCD46/hTBM group was lower than that in the WT group and pig erythrocyte binding level with IgG was lower than that in the ABO-I group (all P<0.05). Conclusions The immunocompatibility of genetically modified pig erythrocytes is better than that of wild-type pigs and close to that of ABO-C pigs. Humanized pig erythrocytes may be considered as a blood source when blood sources are extremely scarce.

The goal is to identify new biomarkers for maternal and infant diseases and provide scientific evidence for risk prediction related to maternal diseases and neonatal health.

Objective:To explore the safety and efficacy of serial expansion without delay for the treatment of giant congenital melanocytic nevi (GCMN) on the back.Methods:The clinical date of children with GCMN on the back admitted to the Ninth Department of Plastic Surgery, Plastic Surgery Hospital, Chinese Academy of Medical Sciences from February 2017 to March 2019 were retrospectively analyzed. In stage Ⅰ, an expander was placed on each side of the back to laterally expand the skin on the back, as a whole. In stage Ⅱ, after the expanders were removed and part of the nevus was removed, the expanded flaps were advanced integrally across the back with additional incisions on both sides of the trunk. The new expanders were then placed under the expanded flaps simultaneously for serial expansion. In stage Ⅲ, the expanded flaps were used to reconstruct the wound after resection of GCMN. The color, texture of the flaps and the postoperative scar on the back were observed.Results:Ten patients were enrolled, including 4 males and 6 females, with an average age of 3.4 years (ranged between 2-6 years). All patients completed three stages of treatment. In the second stage, new expanders were placed under the expanded flap for serial expansion simultaneously. The three-stage operation took a total of 6.80 to 11.77 months, and all the nevus on the back were removed. The mean follow-up time was 16.6 months (ranged between 12-24 months). In one case, the skin flap necrosis (1.5 cm × 1.2 cm) was caused by abrasion at the end of stage Ⅱ when the inflation of the expander was nearly completed, without exposure of the dilator. After the expanders were removed in stage Ⅲ, the flap survived well. In the other children, no wound dehiscence, infection, dilator exposure and other complications occurred. The back was maintained as a whole aesthetic unit without conspicuous scars and the postoperative scars were located on the sides of the trunk. The color and texture of the flap were similar to its surrounding tissue.Conclusions:Serial expansion without delay is safe and efficient in the treatment of GCMN on the back. It not only eliminates the need to wait 4 to 15 months for the expander implantation, but also saves one operation and anesthesia. During the treatment, additional incisions are only made on both sides of the trunk, which could maintain the back as a whole aesthetic unit and obtain a better postoperative appearance.

Objective:To explore the application value of automated machine learning (autoML) model in predicting the risk of preeclampsia in the first trimester.Methods:From January 2017 to October 2020, 2 180 singleton pregnant women who were registered in Jinan Second Maternal and Child Health Hospital and underwent pregnancy examination at 12 weeks of gestation were selected. The pregnant women were divided into preeclampsia group (103 cases) and control group (2 077 cases) according to the occurrence of preeclampsia. The differences in clinical data and hematological indexes in the two groups were compared, and the correlation between each index and the risk of preeclampsia was analyzed too. All the pregnant women were randomly divided into training set and test set according to the ratio of 7∶3, and the autogluon autoML algorithm was used to build a variety of machine learning models, and training and cross-validation were performed in the training set to compare the accuracy of the different models. The importance of each index in the autoML model was analyzed, and the autoML model and the logistic regression model were used to predict the risk of preeclampsia in pregnant women in the test set respectively, and the receiver operating characteristic (ROC) curve was used to evaluate the prediction performance of the autoML and the logistic regression model.Results:The age, pre-pregnancy body mass index, body mass index at 12 weeks of gestation, waist circumference at 12 weeks of gestation, proportion of drinking history, high-sensitivity C-reactive protein (hs-CRP), triglyceride, low-density lipoprotein cholesterol (LDL-C), aspartate aminotransferase (AST), platelet distribution width (PDW), mean platelet volume, thyroid stimulating hormone (TSH) and β-human chorionic gonadotropin were all significantly higher than those in the control group (all P<0.05), and the free tri-iodothyronine (free T3), free thyroxine (free T4), placental growth factor (PIGF), soluble fms-like tyrosine kinase-1 (sFlt-1) and pregnancy-associated plasma protein-A (PAPP-A) were all significantly lower than those in the control group (all P<0.05). Correlation analysis showed that the correlation between pre-pregnancy body mass index, body mass index at 12 weeks gestation, waist circumference at 12 weeks gestation, hs-CRP, triacylglycerol, AST, TSH, free T3, free T4, β-HCG, PIGF, sFlt-1, PAPP-A and preeclampsia risk were obviously higher; but the correlation between each index were lower. A total of 18 models in 8 categories were constructed with the autoML model algorithm, and the neural network _L2 based on FastAI had the highest accuracy in the training set (0.963) and the validation set (0.971). The TSH, LDL-C, PDW, waist circumference at 12 weeks of gestation, sFlt-1, AST were more important in the model, while the free T4, total cholesterol, pregnancy times, drinking history, parity and family history of hypertension were less important indicators. The area under the ROC curve of the autoML model for predicting the risk of preeclampsia in the first trimester was significantly higher than that of the logistic regression model (0.984 vs 0.765, P=0.002), while there was no statistical difference in the prediction accuracy of the two prediction models in the training set ( P>0.05). The prediction accuracy and sensitivity of the autoML model in the test set were both significantly higher than those of the logistic regression model (99.54% vs 98.32%, 93.75% vs 75.00%, both P<0.05). Conclusions:Factors such as TSH, LDL-C, PDW, waist circumference, sFlt-1 and AST in the first trimester of pregnancy have a certain correlation with the risk of preeclampsia. The autoML model based on the indicators of the first trimester has a high predictive value for the risk of preeclampsia.

Objective:To investigate the risk factors of acute gastrointestinal failure in patients with traumatic brain injury(TBI).Methods:A retrospective analysis of 297 patients admitted to the Rugao Hospital Affiliated to Nantong University for traumatic brain injury from March 2018 to March 2020 was performed. Multivariate Logistic regression analysis was used to test the risk factors of acute gastrointestinal failure in patients with traumatic brain injury.Results:Of the 297 patients with TBI, 92 (30.98%) had acute gastrointestinal failure, of which 56 (18.86%) were acute gastrointestinal injury(AGI) Ⅲ and 36 (12.12%) were AGI Ⅳ. Multivariate Logistic regression analysis showed that female, low Glasgow Coma Scale (GCS) scores, frontal lobe injury, abnormal serum sodium, lung infection and intracranial infection were independent risk factors for acute gastrointestinal failure in TBI patients ( P<0.05). The length of ICU stay in the acute gastrointestinal failure group was significantly higher than that of the non-acute gastrointestinal failure group: (18.5 ± 2.6) d vs. (6.3 ± 1.2) d, and the incidence of good prognosis was significantly lower than that of the non-acute gastrointestinal failure group: 60.87%(56/92) vs. 80.49(165/205), the differences were statistically significant ( P<0.05). Conclusions:That female, low GCS scores, frontal lobe injury, abnormal serum sodium, lung infection and intracranial infection are independent risk factors for acute gastrointestinal failure in TBI patients
