ObjectiveTo observe the clinical efficacy and safety of Tangning Tongluo tablets in the treatment of nonproliferative diabetic retinopathy （DR）. MethodsFourteen research centers participated in this study， which spanned a time interval from September 2021 to May 2023. A total of 240 patients with nonproliferative DR were included and randomly assigned into an observation group （120 cases） and a control group （120 cases）. The observation group was treated with Tangning Tongluo tablets， and the control group with calcium dobesilate capsules. Both groups were treated for 24 consecutive weeks. The vision， DR progression rate， retinal microhemangioma， hemorrhage area， exudation area， glycosylated hemoglobin （HbA1c） level， and TCM syndrome score were assessed before and after treatment， and the safety was observed. ResultsThe vision changed in both groups after treatment （P<0.05）， and the observation group showed higher best corrected visual acuity （BCVA） than the control group （P<0.05）. The DR progression was slow with similar rates in the two groups. The fundus hemorrhage area and exudation area did not change significantly after treatment in both groups， while the observation group outperformed the control group in reducing the fundus hemorrhage area and exudation area. There was no significant difference in the number of microhemangiomas between the two groups before treatment. After treatment， the number of microhemangiomas decreased in both the observation group （Z=-1.437， P<0.05） and the control group （Z=-2.238， P<0.05）， and it showed no significant difference between the two groups. As the treatment time prolonged， the number of microhemangiomas gradually decreased in both groups. There was no significant difference in the HbA1c level between the two groups before treatment. After treatment， the decline in the HbA1c level showed no significant difference between the two groups. The TCM syndrome score did not have a statistically significant difference between the two groups before treatment. After treatment， neither the TCM syndrome score nor the response rate had significant difference between the two groups. With the extension of the treatment time， both groups showed amelioration of TCM syndrome compared with the baseline. ConclusionTangning Tongluo tablets are safe and effective in the treatment of nonproliferative DR， being capable of improving vision and reducing hemorrhage and exudation in the fundus.

Objective:To investigate the effects of minimally invasive aspiration and drainage combined with hyperbaric oxygen (HBO) therapy on inflammatory factors and cerebrovascular dynamic indicators in patients with hypertensive intracerebral hemorrhage.Methods:A total of 74 patients with hypertensive intracerebral hemorrhage treated in 454 Hospital and Nanjing Zijin Hospital from January 2019 to January 2021 were selected and randomly divided into treatment group ( n=37) given minimally invasive aspiration and drainage combined with HBO therapy and control group ( n=37) given minimally invasive aspiration and drainage only. The levels of serum inflammatory factors, cerebrovascular dynamic indicators, arterial blood gas (ABG) levels, and the neurologic function scores in the two groups before and after treatment were compared. Results:Before treatment, there was no significant difference between the two groups in the levels of serum inflammatory factors, cerebrovascular dynamic indicators, ABG levels, and the neurological function scores ( P>0.05); after 30 days of treatment, the levels of inflammatory factors such as tumor necrosis factor-α (TNF-α), interleukin-1(IL-1), and IL-8 in the treatment group were lower than those in the control group, the National Institute of Health Stroke Scale (NIHSS) scores, the values of peripheral resistance (PR) and dynamic resistance (DR) in the treatment group were lower than those in the control group, while the Mini-mental State Examination (MMSE) scores, the mean blood flow velocities (Vm), mean blood flow quantities (Qm), the arterial partial pressures of CO 2 (PaCO 2) and the arterial partial pressures of oxygen (PaO 2), and the blood pH values in the treatment group were higher than those in the control group ( P<0.05), and all the differences were statistically significant ( P<0.05). Conclusion:Minimally invasive aspiration and drainage combined with HBO therapy in the treatment of hypertensive intracerebral hemorrhage can effectively reduce the patients’ inflammatory response and promote the recovery of cerebral vascular dynamics and nerve function.
