Objective: To observe the clinical efficacy of minimally invasive vitreous surgery (MIVS) for special rhegmatogenous retinal detachment (RRD) in children and adolescents. Methods: A retrospective clinical comparative study. Fourteen eyes with special type of RRD in 14 children and adolescents who received the MIVS treatment from January 2014 to January 2019 in Ophthalmology Department of The First Affiliated Hospital Ophthalmology of Air Force Military Medical University, were included in this study. Among them, 8 eyes from 8 males and 6 eyes from 6 females. The age of them ranged from 5 to 17, with the mean age of 12.64±4.11 years. The course of disease was ranged from 1 d to 1 year, and the average of it was 30 d. All the eyes developed the special type RRD, including pseudophakic and aphakic retinal detachment, giant retinal tear with retinal detachment, choroidal detachment associated with retinal detachment, and RRD with ocular dysplasia. In the 14 eyes, there was 2 eyes with retinal detachment in 1 quadrant, 4 eyes in 2 quadrants, 1 eye in 3 quadrants and 7 eyes in total 4 quadrants. All the eyes were treated with 23G or 25G MIVS and filled with irrigation solution, air and silicone oil. In addition, 10.4 months' follow-up for average after surgery were taken to observe the occurrence of retinal reattachment, BCVA and related complications in the eyes. Results: In the 14 eyes, 13 (92.9%) of them attained retinal reattachment and 1 eye (7.1%) got a poor retinal reattachment after one operation. At the last follow-up, all the 14 eyes (100.0%) attained retinal reattachment and 5 of them at the filling state of silicone oil. The vision of 8 eyes (57.1%) were improved, 4 eyes (28.6%) have no notable changes and 2 eyes decreased (14.3%). During the operation, iatrogenic retinal breaks were occurred in 1 eye, and silicone oil entered underneath the retina in 1 eye. After the operation, 1 eye suffered a relapse of retinal detachment after the removal of silicone oil and then were filled with it again. Conclusions MIVS is a safe and effective way to treat the special type RRD among the children and adolescents. The rate of retinal reattachment is 92.9% after one surgery and 100.0% at the last follow-up. Therefore, MIVS can help most of eyes with special type RRD to get a stable and improved vision.

Objective To investigate the effect of Danggui buxue decoction on ventricular remodeling and miR-34a expression after myocardial infarction in mice. Methods Mice myocardial infarction model were estab-lished by the left anterior descending coronary artery embolization. Then the mice were divided into Danggui buxue Decoction group and model group. Mice in Danggui buxue decoction group were given Danggui buxue decoction , and mice in the model group were given the equal volume of saline for 8 weeks. Cardiomyocyte apoptosis was detect-ed by TUNEL staining. Myocardial fibrosis was detected by Masson staining. The expression of miR-34a was detect-ed by quantitative PCR and the expression of Sirt1 was detected by Western blot assay. Results Compared with the model group ,the EF value of the mice was significantly improved (P < 0.05),the myocardial cell index decreased(P<0.05),the content of collagen fibers decreased(P<0.05),the expression of miR-34a decreased, but the expression of Sirt1 increased(P<0.05)in Danggui buxue Decoction group. Conclusion Danggui buxue decoction can effectively inhibit ventricular remodeling of mice following myocardial infarction ,which is associated with the suppression of miR-34a and the increase of Sirt1.

Objective:To investigate the predicting effect of the disrupted functional connectivity of the anterior cingulate cortex (ACC) on the efficacy of non-steroidal anti-inflammatory drugs (NSAIDs) in patients with migraineurs without aura (MwoA).Methods:From January 2019 to January 2021, seventy patients with migraine and thirty-three healthy people in the same period were selected.The functional connectivity analysis based on the ACC was used in MwoA patients with NSAIDS-effective ( n=35), MwoA patients with NSAIDS-ineffective ( n=35), and healthy controls (HCs) ( n=33). The abnormal resting-state functional connectivity patterns among the three groups were analyzed to reveal potential correlations with clinical characteristics in migraine. Then the receiver operating characteristic (ROC) curve was used to analyze the predictive ability of the abnormal ACC functional connectivity on the efficacy of NSAIDs in patients with MwoA. Results:(1)Compared with the MwoA patients with NSAIDs-ineffective, the MwoA patients with NSAIDs-effective showed higher functional connectivity between bilateral ACC and left middle cingulate cortex (MCC) (MNI: x, y, z=0, -24, 48, cluster=14, t=3.380) and postcentral gyrus (PoCG)( MNI: x, y, z=-21, -45, 69, cluster=12, t=3.016) (all P<0.005, Bonferroni correction). Compared with the HCs, patients with MwoA showed increased functional connectivity between left ACC and ipsilateral inferior parietal lobule, middle frontal gyrus (MFG) and angular gyrus (AG), and between right ACC and right precuneus, bilateral MFG and left AG (all P<0.005, Bonferroni correction). (2)There was a positive correlation between the functional connectivity of right ACC to right precuneus and MIDAS scores ( r=0.375, P=0.035) in MwoA patients with NSAIDs-effective. In MwoA patients with NSAIDs-ineffective, there were also significant correlations between the functional connectivity of left ACC to ipsilateral AG and MFG and headache onset duration ( r=0.357, P=0.045) and disease duration ( r=-0.367, P=0.039). (3)ROC curve analysis showed that the area under the curve (AUC) for the functional connectivity between the right ACC and left MCC and between the left ACC and left PoCG to predict the efficacy of NSAIDs were 0.728 and 0.736, respectively. Conclusions:Resting-state functional connectivity of the ACC is involved in the evaluation and prediction for analgesic efficacy of NSAIDs in migraine patients, which provides neuroimaging evidence for further investigations on the neurophysiological mechanism of migraine and assistance in clinical individualized precise treatment.

OBJECTIVES: This study aimed to observe the clinical and immune response characteristics of vaccinated persons infected with the delta variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Yangzhou, China. METHODS: We extracted the medical data of 129 patients with delta-variant infection who were admitted to Northern Jiangsu People's Hospital (Yangzhou, China) between August and September, 2021. The patients were grouped according to the number of vaccine doses received into an unvaccinated group: a one-dose group and a two-dose group. The vaccine used was SARS-CoV-2-inactivated vaccine developed by Sinovac. We retrospectively analyzed the patients' epidemiological, clinical, laboratory, and imaging data. RESULTS: Almost all patients with delta-variant infection in Yangzhou were elderly, and patients with severe/critical illness were over 70 years of age. The rates of severe/critical illness (P=0.006), fever (P=0.025), and dyspnea (P=0.045) were lower in the two-dose group than in the unvaccinated group. Compared to the unvaccinated group, the two-dose group showed significantly higher lymphocyte counts and significantly lower levels of C-reactive protein (CRP), interleukin-6 (IL-6), and D-dimer during hospitalization and a significantly higher positive rate of immunoglobulin G (IgG) antibodies at admission (all P<0.05). The cumulative probabilities of hospital discharge and negative virus conversion were also higher in the two-dose group than in the unvaccinated group (P<0.05). CONCLUSIONS Two doses of the SARS-CoV-2-inactivated vaccine were highly effective at limiting symptomatic disease and reducing immune response, while a single dose did not seem to be effective.

BACKGROUNDLowering intraocular pressure (IOP) is currently the only therapeutic approach in primary open-angle glaucoma. and the fixed-combination medications are needed to achieve sufficiently low target IOP. A multicenter prospective study in the Chinese population was needed to confirm the safety and efficacy of Bimatoprost/Timolol Fixed Combination Eye Drop in China. In this study, we evaluated the safety and efficacy of Bimatoprost/Timolol Fixed Combination with concurrent administration of its components in Chinese patients with open-angle glaucoma or ocular hypertension.

METHODSIn this multicenter, randomized, double-masked, parallel controlled study, patients with open-angle glaucoma or ocular hypertension who were insufficiently responsive to monotherapy with either topical β-blockers or prostaglandin analogues were randomized to one of two active treatment groups in a 1:1 ratio at 11 Chinese ophthalmic departments. Bimatoprost/timolol fixed combination treatment was a fixed combination of 0.03% bimatoprost and 0.5% timolol (followed by vehicle for masking) once daily at 19:00 P.M. and concurrent treatment was 0.03% bimatoprost followed by 0.5% timolol once daily at 19:00 P.M. The primary efficacy variable was change from baseline in mean diurnal intraocular pressure (IOP) at week 4 visit in the intent-to-treat (ITT) population. Primary analysis evaluated the non-inferiority of bimatoprost/ timolol fixed combination to concurrent with respect to the primary variable using a confidence interval (CI) approach. Bimatoprost/timolol fixed combination was to be considered non-inferior to concurrent if the upper limit of the 95% CI for the between-treatment (bimatoprost/timolol fixed combination minus concurrent) difference was ≤ 1.5 mmHg. Adverse events were collected and slit-lamp examinations were performed to assess safety. Between-group comparisons of the incidence of adverse events were performed using the Pearson chi-square test or Fisher's exact test.

RESULTSOf the enrolled 235 patients, 121 patients were randomized to receive bimatoprost/timolol fixed combination and, 114 patients were randomized to receive concurrent treatment. At baseline the mean value of mean diurnal IOP was (25.20 ± 3.06) mmHg in the bimatoprost/timolol fixed combination group and (24.87 ± 3.88) mmHg in the concurrent group. The difference between the treatment groups was not statistically significant. The mean change from baseline in mean diurnal IOP (± standard deviation) in the bimatoprost/timolol fixed combination group was (-9.38 ± 4.66) mmHg and it was (-8.93 ± 4.25) mmHg in the concurrent group (P < 0.01). The difference between the two treatment groups (bimatoprost/timolol fixed combination minus concurrent) in the change from baseline of mean diurnal IOP was -0.556 mmHg (95% CI: -1.68, 0.57, P = 0.330). The upper limit of the 95% CI was less than 1.5 mmHg, the predefined margin of non-inferiority. Adverse events occurred in 26.4% (32/121) of the bimatoprost/timolol fixed combination patients and 30.7% (35/114) of the concurrent patients. The most frequent adverse event was conjunctival hyperemia, which was reported as treatment related in 16.5% (20/121) in the bimatoprost/timolol fixed combination group and 18.4% (21/114) in the concurrent group (P > 0.05).

CONCLUSIONSBimatoprost/Timolol Fixed Combination administered in Chinese patients with open-angle glaucoma or ocular hypertension was not inferior to concurrent dosing with the individual components. Safety profiles were similar between the treatment groups.
