Proteolysis-targeting chimeras (PROTACs) have emerged as a promising therapeutic strategy for targeted protein degradation. However, the clinical application of PROTACs may be hindered by off-target toxicity resulting from non-tissue-specific protein degradation and ingenious prodrug strategies may open new avenues to addressing this concern. Herein, we propose a light-induced positive feedback strategy to use photodynamic therapy (PDT) to improve the activation efficiency of PROTAC prodrugs, monitor PROTAC release, and combine PROTAC to induce tumor cell apoptosis. In the hypoxic tumor microenvironment, the azo bond in AZO-PRO selectively cleaves, triggering the release of the potent protein degrader PRO and the multifunctional photosensitizer. Once activated, the fluoresce signal of the photosensitizer dramatically recovers, allowing monitoring of prodrug activation. Additionally, upon irradicating the tumor site using near-infrared (NIR) laser, PDT exacerbates tumor hypoxia, further promoting AZO-PRO activation. Our work introduces a novel approach to efficiently track and activate PROTAC prodrugs, enhance their antitumor efficacy, and mitigate off-target systemic toxicity.

Objective:To investigate the efficacy of Tanzhuo Decoction in the treatment of early diabetic nephropathy in patients with type 2 diabetes mellitus and its effect on cystatin C (Cys-C), C-reactive protein (CRP), urinary albumin excretion rate (UAER), and creatinine clearance rate (CCr). Methods:Eighty patients with type 2 diabetes mellitus complicated by early diabetic nephropathy who received treatment at Maanshan Hospital of Traditional Chinese Medicine from 2019 to 2021 were included in this randomized controlled study. They were divided into a control group ( n = 40) and a treatment group ( n = 40) using the random number table method. Patients in the control group received conventional therapy including blood glucose and blood pressure control, while those in the treatment group received Tangzhuo Decoction in addition to the same treatment as that given to the control group. Both groups of patients were treated for 30 days. The clinical efficacy as well as pre- and post-treatment Cys-C, CRP, UAER, and CCr were compared between the two groups. Results:The total response rate in the treatment group was 92.5% (37/40), which was significantly higher than 75.0% (30/40) in the control group ( χ2 = 4.50, P < 0.05). After treatment, Cys-C, CRP, and UAER in the treatment group were (2.04 ± 0.08) mg/L, (3.97 ± 1.71) mg/L, and (91.18 ± 18.68) μg/min, respectively, which were significantly decreased compared with those before treatment ( t = 12.14, 5.59, 4.73, all P < 0.05). After treatment, CCr in the treatment group was (56.3 ± 5.01) mL/min, which was significantly increased compared with that before treatment ( t = -8.56, P < 0.05). After treatment, Cys-C, CRP, and UAER in the control group were (2.17 ± 0.04) mg/L, (4.66 ± 1.47) mg/L, and (103.93 ± 22.62) μg/min, respectively, which were significantly decreased compared with those before treatment ( t = 4.05, 5.00, 2.24, all P < 0.05). After treatment, CCr in the control group was (45.9 ± 4.9) mL/min, which was significantly increased compared with that before treatment ( t = -3.98, P < 0.05). There were significant differences in Cys-C, UAER, and CCr between the treatment and control groups ( t = -7.42, -2.29, 7.82, all P < 0.05). Conclusion:Tanzhuo Decoction for the treatment of early diabetic nephropathy in patients with type 2 diabetes mellitus has a definite effect. It can effectively reduce levels of Cys-C and UAER, reduce inflammatory reactions, improve kidney function, and delay the progression of kidney injury.

Objective To investigate the predictive value of adductor 3(ADD3)and matrix metalloprotein-ase 14(MMP14)in peripheral blood of patients with acute ST segment elevation myocardial infarction(STE-MI)for acute heart failure(AHF).Methods A total of 98 STEMI patients admitted to the inpatient depart-ment of the Department of Cardiology of the hospital from November 2019 to October 2022 were selected as the STEMI group.STEMI patients were divided into AHF group(30 cases)and non AHF group(68 cases)according to whether AHF occurred within 48 hours of onset,and 63 healthy volunteers who urderwent the physical examination in the hospital were selected as control group.The levels of ADD3 and MMP14 in pe-ripheral blood was detected,and their relationship with AHF in STEMI patients and the value in predicting AHF were analyzed.Results The level of ADD3 in peripheral blood in STEMI group was lower than that in the control group(P＜0.05),and MMP14 level was higher than that in the control group(P＜0.05).The level of ADD3 in peripheral blood in AHF group was lower than that in non AHF group(P＜0.05),and the level of MMP14 was higher than that in non AHF group(P＜0.05).The level of ADD3 in peripheral blood of STEMI patients was negatively correlated with cardiac troponin Ⅰ(cTnI),creatine kinase isoenzyme(CK-MB),brain natriuretic peptide(BNP),and Killip grading(P＜0.05),and the level of MMP14 was positively correlated with cTnI,CK-MB,BNP,and Killip grading(P＜0.05).Killip grade Ⅳ,high BNP level and high MMP14 level were risk factors for complications of AHF in STEMI patients(P＜0.05),and high ADD3 level was a protective factor(P＜0.05).The area under the curve of the combination of ADD3,MMP14 and BNP for predicting AHF in STEMI patients was 0.890,which was greater than 0.704,0.702,0.750 of individual indicators alone(P＜0.05).Conclusion ADD3 level in peripheral blood of STEMI patients is decreased and MMP14 level is increased,which is associated with complication of AHF.ADD3 and MMP14 are expected to be biological indicators of AHF in STEMI patients.

The most common cause of primary hyperparathyroidism (PHPT) is parathyroid adenoma. Surgery is the most effective method to treat PHTP. The data of 10 patients who underwent endoscopic complete areola approach for parathyroid adenoma resection in our hospital from Jan. 2018 to Oct. 2021 were reviewed. It is considered that this method is feasible and has certain advantages compared with traditional surgery.

To explore the epidemiological characteristics, trends and relevant factors of pre-hospital mortality due to acute myocardial infarction (AMI) from 1999 to 2016 in Tianjin city, based on mortality surveillance information and household registration population information. Standardized mortality rates were calculated using the year 2000 world standard population. From 1999 to 2016, the research result showed that the pre-hospital crude mortality rates of AMI were 39.47/100 000 to 90.64/100 000 and the standardized mortality rates were 30.92/100 000 to 53.90/100 000. The proportion of pre-hospital AMI deaths was 73.96%-81.92% (t=1.09, P>0.05) within the same period. Aged, female, rural residents, unmarried, divorced, widowed, low education level, and outdoor workers have a relative higher proportion of pre-hospital AMI mortality.

Objective: To evaluate and compare the surgery prognosis of the papillary thyroid carcinoma (PTC) patients who underwent conventional and endoscopic thyroidectomies via areola. Methods: From January 2012 to December 2017, 887 patients with PTC underwent thyroidectomy. The A group of 693 patients underwent traditional thyroidectomy, and B group of 194 patients underwent endoscopic thyroidectomy. Clinicopathologic characteristics, surgical methods, pathological features and complications were analyzed and compared between two groups. Results: The mean age of A group was older than B group: (45.2 ± 11.5) years vs. (34.9 ± 9.4) years, P<0.01. The drainamount and drain maintenance in B group were significantly higher than those in A group (P<0.01). The operative methods in two group had significant difference (P<0.01). The patients in B group were successful in operation and no one transferred to open operation. The tumor size in the A group was larger than that in B group, and more bilateral multifocal tumors were in A group (P<0.01). The number of lymph nodes dissection in A group was more than that in B group (P<0.01). There was no significant difference in the postoperative complications (P > 0.05). Conclusions The results show that patients with PTC who underwent conventional and endoscopic thyroidectomies via areola have similar surgical prognosis.Therefore, choosing the appropriate cases for endoscopic thyroidectomy via breast areola approach may be regarded as an alternative surgical technique to conventional thyroidectomy which has the oncological safety and cosmetic results.

Objective To explore the value and method of using carbon nanoparticles in endoscopic treatment of papillary thyroid microcarcinoma.Method 74 cases were randomly divided into two groups,34 cases in experimental group which were injected with carbon nanoparticles,and 40 cases in the control group without any injection.All cases were analyzed in terms of the tumor size,the number of lymph nodes and parathyroid gland injury.Results All patients underwent the operation smoothly.The postoperative pathological specimens result showed there was no statistical difference of carcinoma size between the two groups.The number of lymph nodes dissected was 177 in the control group and 220 in the experimental group (the rate of lymph node black staining rate was 89％).In the experimental group,the average number of lymph node detected in each patient was 6.47±2.13,more than 4.42±1.91 in the control group.The number of parathyroid glands found in the experimental group was 3 and 11 in the control group,and the difference had no statistical significance.Postoperative temporary laryngeal recurrent nerve injury occurred to 2 cases in each group,and no statistical difference was found.Conclusion Using carbon nanoparticles in endoscopic treatment of papillary thyroid microcarcinoma can increase the detection rate of lymph node,and to some extent,reduce the parathyroid injury.It has a certain clinical significance,However,care should be taken to avoid contamination of the mirror field of view.

This paper performs a comprehensive study on the computer-aided detection for the medical diagnosis with deep learning. Based on the region convolution neural network and the prior knowledge of target, this algorithm uses the region proposal network, the region of interest pooling strategy, introduces the multi-task loss function: classification loss, bounding box localization loss and object rotation loss, and optimizes it by end-to-end. For medical image it locates the target automatically, and provides the localization result for the next stage task of segmentation. For the detection of left ventricular in echocardiography, proposed additional landmarks such as mitral annulus, endocardial pad and apical position, were used to estimate the left ventricular posture effectively. In order to verify the robustness and effectiveness of the algorithm, the experimental data of ultrasonic and nuclear magnetic resonance images are selected. Experimental results show that the algorithm is fast, accurate and effective.
