Objective:To observe the clinical effect of adjustable silicone strap suspension in the treatment of myasthenia gravis ptosis.Methods:From January 2019 to January 2020, 60 patients with myasthenia gravis ptosis (35 males, 25 females, age distribution from 25 to 58 years, with average of 35.63 years) were collected from the Department of Ophthalmoplasty of Aier Eye Hospital affiliated to Wuhan University. They were divided into control group and observation group, with 30 cases in each group. The observation group was treated with adjustable silicone band suspension, and the correction effect, satisfaction, recovery status, ocular surface function index, recurrence rate and complications of the two groups were compared.Results:The excellent rate of operation in the observation group was 93.33% (28/30), which was significantly higher than 63.33% (19/30) in the control group (χ 2=6.29, P<0.05), and the satisfaction of patients in the observation group was 100% (30/30), which was significantly higher than 76.67% (23/30) in the control group (χ 2=5.82, P<0.05). The preoperative corneal curvature and fluorescein staining in the observation group and the control group were significantly lower than those in the postoperative state ( t=6.17, 21.48, P<0.05). The corneal curvature and fluorescein staining score of the observation group were significantly higher than those of the control group at 3 months after surgery ( t=3.00, 9.06, P<0.05). There was no significant difference between the two groups in the incidence of complications such as eyelid imclosure, upper eyelid inversion and unnatural upper eyelid curvature (χ 2=0.19, P>0.05). Follow up at 3 months after surgery, the recurrence rate in the observation group was lower than that in the control group (χ 2=4.63, P<0.05). Conclusions:Surgery is an option for patients with myasthenia gravis ptosis who are not responding well to medical treatment and whose condition is stable. Adjustable silicone strap suspension for the treatment of myasthenia gravis ptosis can significantly improve the surgical success rate and patient satisfaction, with low postoperative complication rate and recurrence rate, which is suitable for clinical application.

Objective:To evaluate the short-term rehabilitation effect of wearable visual training devices based on extended reality (XR) glasses in patients after macular hole surgery.Methods:A self-controlled study was conducted.Eleven patients with monocular low vision after macular hole surgery were recruited at Renmin Hospital of Wuhan University from October 2022 to March 2024.All patients underwent biofeedback training for 3 months using the independently developed visual rehabilitation training glasses LOOKBON T10.The LogMAR best corrected visual acuity (BCVA), retinal sensitivity, effective fixation rate, fixation stability, reading speed, vertical metamorphopsia (MV), horizontal metamorphopsia (MH), and Chinese version of the visual-related quality of life assessment form (CVRQoL-25) were compared before and after training.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Renmin Hospital of Wuhan University (No.WDRY2024-K263).Written informed consent was obtained from each subject.Results:After training, the patients' BCVA, retinal sensitivity, effective fixation rate, fixation stability, and reading speed were 0.69±0.19, (21.61±2.75)db, (92.43±4.06)%, (93.09±4.31)%, and (104.82±21.85) characters/minute, respectively, which were significantly improved compared to 0.85±0.28, (17.71±3.17)db, (31.83±19.05)%, (32.35±19.12)%, and (69.64±20.17) characters/minute before training ( t=5.253, -5.987, -11.561, -12.003, -11.682; all at P<0.001).After training, MV and MH were (0.29±0.20)° and (0.21±0.24)°, respectively, which were significantly reduced compared to pre-training (0.44±0.24)° and (0.43±0.41)° ( t=9.238, 4.068; both at P<0.01).After training, the CVRQoL-25 score was 1 193.18±229.43, which was significantly higher than pre-training 947.73±203.86 ( t=-11.687, P<0.001). Conclusions:The application of wearable visual training equipment based on XR glasses can effectively improve the visual function of patients with poor visual function recovery after macular hole surgery, and enhance their quality of life.

Objective Through the combined detection method,we tried to find more sensitive biomarkers for the diagnosis of acute TBI,which might provide the exact diagnosis,treatment and monitoring indicators for the clinic.Methods A total of 156 patients with acute TBI admitted to the Emergency Traumatic Center of Yan'an Hospital of Kunming from October 2022 to June 2023 were collected and included the normal and fracture control groups.Peripheral blood samples of the enrolled patients were collected and monitored,S100β and IL-6 were tested and clinical data such as hs-CRP was collected immediately upon admission,then statistical analysisanalysis was conducted.Results Peripheral blood in patients with acute TBI,The levels of S100β,IL-6 and hs-CRP significantly increased,and the area under the ROC curve for diagnosing acute TBI was 0.944,0.915,and 0.897.The combined detection of the three indicators showed an area under the ROC curve of up to 0.975.Person correlation analysis found a positive correlation between the three indicators,especially S100β with IL-6,The correlation coefficient between them is 0.715.Binary logistic regression analysis found that S100β,IL-6 and hs-CRP are independent risk factors for acute TBI.Conclusions The combined detection of S100β,IL-6 and hs-CRP can effectively improve the sensitivity of acute TBI diagnosis.The mutual promotion of S100β and IL-6 may aggravate the secondary craniocerebral injury caused by inflammatory mechanism,and early targeted treatment may improve the prognosis.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Parkinson's disease (PD) is a chronic neurodegenerative disease. At present, levodopa and other drugs are mainly used for dopamine supplementation therapy. However, the absorption of levodopa in the gastrointestinal tract is unstable and its half-life is short, and long-term use of levodopa will lead to the end-of-dose deterioration, dyskinesia, the "ON-OFF" phenomenon and other symptoms. Therefore, new preparations need to be developed to improve drug efficacy, reduce side effects or improve compliance of patients. Based on the above clinical needs, this review briefly introduced the preparation modification strategies for the treatment of PD through case analysis, in order to provide references for the research and development of related preparations.

Methods: From September 3, 2018, to March 23, 2024, participants with essential hypertension (receiving antihypertensive medication treatment, hypertension group) and normal blood pressure (control group) were recruited from the Cardiology Department of Shanghai Hospital of Traditional Chinese Medicine, the Coronary Care Unit of Shanghai Tenth People's Hospital, the Physical Examination Center of Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, and the Gaohang Community Health Service Center. This study employed the propensity score matching (PSM) method to reduce study participants selection bias. Spectral information in the facial visible light spectrum of the subjects was collected using a flame spectrometer, and the spectral chromaticity values were calculated using the equal-interval wavelength method. The study analyzed the differences in spectral reflectance across various facial regions, including the entire face, forehead, glabella, nose, jaw, left and right zygomatic regions, left and right cheek regions as well as differences in parameters within the Lab color space between the two subject groups. Feature selection was conducted using least absolute shrinkage and selection operator (LASSO) regression, followed by the application of various machine learning algorithms, including logistic regression (LR), support vector machine (SVM), random forest (RF), Naïve Bayes (NB), and eXtreme Gradient Boosting (XGB). The reduced-dimensional dataset was split in a 7 : 3 ratio to establish a classification and assessment model for facial coloration related to primary hypertension. Additionally, model fusion techniques were applied to enhance the predictive power. The performance of the models was evaluated using metrics including the area under the curve (AUC) and accuracy. Shapley Additive exPlanations (SHAP) was used to interpret the outcomes of the models. Results: A total of 114 participants were included in both hypertension and control groups. Reflectance analysis across the entire face and eight predefined areas revealed that the hypertensive group exhibited significantly higher reflectance of corresponding color light in the blue-violet region (P < 0.05) and a lower reflectance in the red region (P < 0.05) compared with control group. Analysis of Lab color space parameters across the entire face and eight predefined areas showed that hypertensive group had significantly lower a and b values than control group (P < 0.05). LASSO regression analysis identified a total of 18 facial color features that were highly correlated with hypertension, including the a values of the chin and the right cheek, the reflectance at 380 nm and at 780 nm of the forehead. The results of the multi-model classification showed that the RF classification model was the most effective, with an AUC of 0.74 and an accuracy of 0.77. The combined model of RF + LR + SVM outperformed a single model in their classification performance, achieving an AUC of 0.80 and an accuracy of 0.76. SHAP model visualization results indicated that the top three contributors to ideal prediction results based on the characteristics from the facial spectrum were the reflectance at 380 nm across the entire face and of the nose as well as the a value of the chin. Conclusion Within the same age group, patients with essential hypertension exhibited significant and regular changes in facial color and facial spectral reflectance parameters after the administration of antihypertensive drugs. Furthermore, facial reflectance indicators, such as the overall reflectance at 380 nm and the a value of the chin, could offer valuable references for clinically assessing the drug efficacy and health status of patients with essential hypertension.

Background: Genetic defects in the human thyroid-stimulating hormone (TSH) receptor (TSHR) gene can cause congenital hypothyroidism (CH). However, the biological functions and comprehensive genotype–phenotype relationships for most TSHR variants associated with CH remain unexplored. We aimed to identify TSHR variants in Chinese patients with CH, analyze the functions of the variants, and explore the relationships between TSHR genotypes and clinical phenotypes. Methods: In total, 367 patients with CH were recruited for TSHR variant screening using whole-exome sequencing. The effects of the variants were evaluated by in-silico programs such as SIFT and polyphen2. Furthermore, these variants were transfected into 293T cells to detect their Gs/cyclic AMP and Gq/11 signaling activity. Results: Among the 367 patients with CH, 17 TSHR variants, including three novel variants, were identified in 45 patients, and 18 patients carried biallelic TSHR variants. In vitro experiments showed that 10 variants were associated with Gs/cyclic AMP and Gq/11 signaling pathway impairment to varying degrees. Patients with TSHR biallelic variants had lower serum TSH levels and higher free triiodothyronine and thyroxine levels at diagnosis than those with DUOX2 biallelic variants. Conclusions We found a high frequency of TSHR variants in Chinese patients with CH (12.3%), and 4.9% of cases were caused by TSHR biallelic variants. Ten variants were identified as loss-of-function variants. The data suggest that the clinical phenotype of CH patients caused by TSHR biallelic variants is relatively mild. Our study expands the TSHR variant spectrum and provides further evidence for the elucidation of the genetic etiology of CH.

Objective To explore the pharmacological effects and regulatory mechanisms of Carthami Flos water extract and its main constituent,hydroxysafflower yellow A(HSYA),on primary dysmenorrhea rats with cold coagulation and blood stasis.Methods Forty-two female specific pathogen-free grade rats aged 6-8 weeks were divided into blank,model,HSYA(0.01 g/kg),ibuprofen(0.04 g/kg),and low(0.06 g/kg),medium(0.20 g/kg),and high(0.40 g/kg)Carthami Flos water extract dose groups using the random number table method,with six rats per group.A rat model was established using ice water bath stimulation combined with estradiol benzoate and oxytocin.Continuous gavage was administered for 6 days from the seventh day of modeling.After the intervention,the writhing reaction test was conducted.The rats,uteri,and ovaries were weighed to calculate the organ index.An enzyme-linked immunosorbent assay and radioimmunoassay were used to detect the prostaglandin E2(PGE2)and prostaglandin F2α(PGF2α)contents in the uterus,thromboxane B2(TXB2)and 6-keto-prostaglondin F1α(6-keto-PGF1α)in plasma,and estradiol(E2)in the serum.Hematoxylin and eosin staining were used to detect the pathological changes in uterine tissue.Immunohistochemistry was used to determine cyclooxygenase-2(COX-2)expression in uterine tissue,whereas immunofluorescence was used to measure follicle-stimulating hormone receptor(FSH-R)expression in ovarian tissue.Western blotting was used to detect gonadotropin-releasing hormone receptor(GnRH-R)and FSH-R expression in uterine tissue.Results Compared with the blank group,the rats in the model group exhibited an increase in uterine and ovarian indices and increased PGE2 and PGF2α in the uterus.TXB2 in the plasma and E2 in the serum were also evaluated.Additionally,6-keto-PGF1α decreased,and COX-2,GnRH-R,and FSH-R expression in the uterus and FSH-R expression in the ovaries also increased(P＜0.05).The morphology of the uterine tissue was disordered.Compared with the model group,the low Carthami Flos water extract dose group showed a decrease in uterine index(P＜0.05).In the medium and high Carthami Flos water extract dose groups,the writhing response decreased,as did the uterine and ovarian indicesand PGE2 and TXB2 contents.The 6-keto-PGF1α content increased,whereas the GnRH-R protein expression in the uterus decreased(P＜0.05).The high Carthami Flos water extract dose group also showed a decrease in PGF2α and FSH-R protein expression in the uterus(P＜0.05).In the HSYA group,the writhing response decreased,the uterine and ovarian indices decreased,the PGE2,PGF2α,and TXB2 contents decreased,and GnRH-R and FSH-R protein expression decreased in the uterus(P＜0.05).The serum E2 levels of the groups that received Carthami Flos water extract at various doses and those of the HSYA group were reduced,and the uterine morphology was improved.COX-2 expression in the uterus and FSH-R protein expression in the ovaries were also reduced(P＜0.05).Conclusion Carthami Flos water extract and HSYA can improve the pathological state of primary dysmenorrhea rats with cold coagulation and blood stasis.Its mechanism may be related to regulating the hypothalamic-pituitary-ovary axis.
