ObjectiveTo explore the effect of Shenge Bushen Capsules （SBC） on sexual development in normal 3-week-old mice. MethodsThe experiment consisted of two parts. In the first part， mice were divided into four groups： The control group and the low， medium， and high-dose SBC groups （234.7， 469.4， 938.7 mg·kg^-1， respectively）. In the second part， mice were divided into four groups： Control group， Pseudostellariae Radix polysaccharide （PRP） group， total flavonoids group， and SBC group， all receiving a dose of 469.4 mg·kg^-1. After 7 days of administration， the vaginal opening of female mice and the descent of testes and scrotum in male mice， as well as the ovarian and testicular organ indices， were observed. After 4 weeks of administration， female and male mice were housed together for 2 days， and the pregnancy rate of females was monitored. After delivery， the pregnant female mice continued receiving the treatment for 4 weeks， and the sexual development of their offspring， including vaginal opening， testicular descent， and organ indices of ovaries and testes， was observed. Serum sex hormones were measured by enzyme-linked immunosorbent assay （ELISA）， and the expression of gonadotropin-releasing hormone （GnRH） and growth hormone （GH） proteins in the hypothalamus was assessed by Western blot. ResultsCompared with the control group， there was no significant effect on the vaginal opening of female mice or the descent of testes in male mice after 7 days of SBC administration. After 4 weeks of administration， the pregnancy rate in the low-dose group was significantly reduced （P<0.05）， but no significant effects were observed in the other groups. The three doses of SBC did not significantly affect the ovarian or testicular organ indices， and there was no significant upregulation in the expression of GnRH or GH in the hypothalamus. The primary component of SBC， Pseudostellariae Radix polysaccharide， significantly reduced the vaginal opening in female mice after 7 days of administration （P<0.05）. After 4 weeks， the serum estradiol levels of non-pregnant female mice were decreased （P<0.05）， but there was no significant effect on the expression of GnRH or GH proteins in the hypothalamus of either male or female mice. Additionally， there were no significant effects on precocious puberty indicators， such as vaginal opening and testicular descent， in the offspring mice. ConclusionSBC does not significantly promote precocious puberty in young mice， and it does not have any noticeable effects on the pregnancy rate of adult mice or the sexual development of their offspring.

AIM: To compare the changes in corneal epithelial thickness(CET)after small incision lenticule extraction(SMILE)and femtosecond laser-assisted in situ keratomileusis(FS-LASIK).METHODS: A total of 187 patients(187 eyes)who underwent either SMILE or FS-LASIK at Urumqi Aier Eye Hospital between December 2022 and November 2023 were collected. The patients were divided into SMILE group and FS-LASIK group according to surgical methods. The CET of the patients was measured by optical coherence tomography(OCT)system before surgery and at 1 wk, 1, 3, and 6 mo postoperatively.RESULTS: Changes in corneal epithelial thickness(△CET)in the central, paracentral, and mid-peripheral regions were compared at 6 mo postoperatively. The SMILE group was characterized by the most significant thickening in the central area and the least thickening in the mid-peripheral area; while the FS-LASIK group was characterized by the most significant thickening in the paracentral area and the least thickening in the mid-peripheral region. At 1 wk, 1, 3, and 6 mo postoperatively, within the 0-7 mm corneal area, the △CET for both the SMILE and FS-LASIK groups was correlated with the preoperative spherical equivalent.CONCLUSION: Within 6 mo postoperatively, both SMILE and FS-LASIK showed a similar trend in epithelial thickening but with distinct characteristics. The change in corneal epithelial thickness for both procedures was positively correlated with the preoperative diopter.

Obesity is a risk factor and pathological basis for various chronic non-communicable diseases and is an important risk factor leading to human mortality and disability.

Currently, the higher pursuit of life and visual quality has led to increased attention to the etiology and prevention of ocular diseases, and the impact of obesity on ocular diseases has been gradually discovered. This article reviews the impact of obesity on certain ocular diseases to deepen the understanding of obesity's impact on ocular diseases and provide a reference for the prevention and treatment of ocular diseases.

AIM: To evaluate the application effectiveness of the 3D surgical video system and intraoperative optical coherence tomography(OCT)in idiopathic epiretinal membrane vitrectomy.METHODS: A retrospective analysis was conducted on 61 patients(61 eyes)with idiopathic epiretinal membrane at our hospital from January 2023 to October 2023. The patients were divided into two groups based on the surgical methods: with 31 patients(31 eyes)who underwent surgery using the 3D surgical video system and intraoperative OCT technology in 3D group, and 30 patients(30 eyes)underwent surgery using the Resight non-contact wide-angle lens system in traditional surgery group. Surgical time, membrane peeling time were recorded, followed-up for 6 mo, post-operative best-corrected visual acuity(BCVA), intraocular pressure(IOP), central macular thickness(CMT), and complications were analyzed for the two groups.RESULTS:All patients successfully underwent surgery without experiencing serious intraoperative complications such as major retinal hemorrhage, retinal tears, or retinal detachment. Additionally, no postoperative complications such as endophthalmitis or secondary glaucoma occurred. The surgical duration and membrane peeling time in the 3D group were significantly shorter than those in the traditional surgery group(20.13±1.59 vs 25.97±2.09 min; 3.74±0.89 vs 8.13±1.72 min, respectively; both P<0.001). There were no significant differences in BCVA and CMT between preoperative and 1-month postoperative values for both groups of patients(both P>0.008). However, both BCVA and CMT improved significantly at 3 and 6 mo postoperatively compared to preoperative levels(both P<0.008). At 6 mo postoperatively, the BCVA in the 3D group was significantly better than that in the traditional surgery group(P=0.007). There were no significant differences in CMT or IOP between the two groups at any postoperative time point(all P>0.05).CONCLUSION: Both the 3D surgical video system and the traditional surgical group can treat idiopathic epiretinal membrane, but the 3D surgical video system has advantages in shortening the surgical time, improving surgical efficiency, and enhancing the precision of surgical steps during surgery with the assistance of intraoperative OCT.

Objective To construct an optimal prediction model of chickenpox in Urumqi, and to provide reference for formulating the prevention and control strategies of chickenpox. Methods The multivariate autoregressive moving average model (ARIMAX) and random forest model (RF) were established based on the monthly incidence of chickenpox in Urumqi from 2014 to 2018, and the monthly incidence of chickenpox in 2019 was used to test the models and evaluate their prediction effect. The prediction performance of the two models was compared, and the best model was selected to predict the incidence of chickenpox in Urumqi. Results The incidence of chickenpox in Urumqi showed a regular bimodal distribution with obvious seasonality, and it showed a slow upward trend from July 2014 to December 2019. The fitting model was ARIMA(0,1,0)(0,1,1)₁₂, the root mean square error (RMSE) and mean absolute error (MAE) of ARIMAX model training set were 1.29 and 0.95, respectively, and the RMSE and MAE of the test set were 1.88 and 1.44, respectively. The training set RMSE and MAE of RF model were 1.56 and 1.56, respectively, and the test set RMSE and MAE were 4.83 and 3.96, respectively. Conclusion The performance of ARIMAX model is better than that of RF model, which can better predict the incidence trend of chickenpox in Urumqi. It is necessary to optimize the prediction model according to the actual situation and provide scientific guidance for the prevention and control of chickenpox.

Corneal alkali burns are a common form of corneal trauma, and their treatment has been a challenge in ophthalmology. Traditional treatments include anti-inflammatory, immunosuppressive, and corneal transplantation, with limited results. This review focuses on the research progress of mesenchymal stem cells(MSCs)and their derived extracellular vesicles(MSCs-EVs)in the treatment of corneal alkali burns. MSCs have the ability of self-renewal, multidirectional differentiation, and immunomodulation, and the MSCs-EVs inherit its function from MSCs. MSCs-EVs inherit the functions of MSCs and has lower immunogenicity and better biocompatibility, which provides a new avenue for ophthalmic treatment. In addition, bioscaffolds are used as scaffolds or drug delivery systems in tissue engineering to promote tissue regeneration due to their excellent biocompatibility and degradability. This article reviews the mechanism of action and research progress of MSCs-EVs and combined bioscaffolds in the treatment of corneal alkali burns, and explores their potential in promoting the repair of corneal alkali burns and improving vision. These findings provide new strategies for the treatment of corneal alkali burns and are expected to improve the prognosis of patients.

Diabetic retinopathy(DR)has emerged as the leading cause of vision loss among working-age people in many countries under the increasing prevalence of diabetes and the longevity of the population. The pathogenesis of DR is complicated and has not been fully elucidated at present, while the treatment methods of DR have not been greatly improved, mainly retinal laser photocoagulation, anti-vascular endothelial growth factor(VEGF)treatment and vitrectomy surgery. The current treatment methods not only have shortcomings, but also bring serious economic burden to patients. Therefore, new methods are needed to explore the pathogenesis of DR, discover new treatments or improve current treatments, and improve the satisfaction of DR patients. In recent years, the identification and quantification of proteins expressed in blood, retina, vitreous humor, aqueous humor, and tears of all observable DR patients and DR rats and differentially expressed proteins after drug intervention have provided new ideas for further exploring the pathogenesis, diagnosis and treatment of DR with the rise of proteomics, which put forward new insights into early detection and treatment.The proteomics of DR in recent years are reviewed, in order to provide new ideas for the diagnosis and treatment of DR.

As a common ophthalmic disease, floaters have a complex etiology. It involves changes in the structure and function of the vitreous body and is closely associated with factors like age and myopia. Vitreous liquefaction and posterior detachment play a crucial role in this regard. Clinically, patients usually experience the floating of dotted or linear black shadows in front of their eyes, and generally, floaters do not cause visual impairment. In the past, due to the limitations of traditional concepts and treatment methods, a conservative observation strategy was often adopted. However, an increasing number of patients have complained that floaters lead to difficulties in driving and reading, which seriously affects their visual quality and mental health. Consequently, the demand for treatment has been growing day by day. The existing treatment options each have their own advantages and disadvantages. The efficacy of drug treatment is limited and remains controversial. Vitrectomy has a definite curative effect, yet it comes with a high risk of complications. YAG laser vitreolysis is relatively safe, but its curative effect is restricted by factors such as the size and location of the opacities. Nanobubble-mediated vitreolysis is still in the research stage and is expected to offer patients safer and more effective treatment in the future. This article reviews the etiology of floaters and the latest progress in its treatment, aiming to deepen clinicians' understanding of floaters, provide a more comprehensive scientific basis for clinical diagnosis and treatment, and promote personalized and precise treatment.
