Diabetic kidney disease （DKD） is one of the more common chronic kidney diseases，and its causes are complex. DKD is very easy to progress to end-stage renal disease，and the current therapeutic effect still needs to be improved. As an important excretive organ of the human body， the kidney has physiological functions such as discharging metabolic waste， regulating fluid balance， and maintaining the stability of the body's internal environment. These highly complex biochemical processes all depend on the energy support provided by mitochondria. Mitochondrial dysfunction is a key factor causing kidney injury， and the imbalance of mitochondrial homeostasis is an important link leading to mitochondrial dysfunction. The occurrence and development of DKD are often accompanied by the imbalance of mitochondrial homeostasis in renal cells. Mitochondrial autophagy， as a means of regulating mitochondrial homeostasis， is very important for the prevention and treatment of DKD. The PTEN-induced putative kinase 1 （PINK1）/Parkin pathway is one of the most classical pathways to regulate mitochondrial autophagy. Recent studies have found that some drugs can regulate the PINK1/Parkin signaling pathway to target mitochondrial homeostasis and exert renoprotective effects. In particular， traditional Chinese medicine has a significant effect on early and middle stage DKD by regulating PINK1/Parkin pathway-mediated mitochondrial autophagy. This article discussed the mechanism of PINK1/Parkin pathway in mitochondrial autophagy and DKD and reviewed the effect of PINK1/Parkin pathway-mediated mitochondrial autophagy on DKD. At the same time， it explored the therapeutic effect of traditional Chinese and western medicine on DKD mediated by PINK1/Parkin-mediated mitochondrial autophagy， aiming to broaden the ideas of traditional Chinese and western medicine for the prevention and treatment of DKD from the perspective of PINK1/Parkin regulating mitochondrial autophagy.

Objective To analyze the clinical characteristics of C-TI-RADS 3 thyroid nodules with a diameter greater than 2 cm and explore their correlation with gender,nodule ingredient,contralateral cancer presence,diffuse echo changes,TPOAB and TGAB.Methods A retrospective analysis was made on the clinical and pathological information of 94 patients with thyroid nodules who were admitted to our department from September 2022 to March 2023.All the patients underwent cytological and/or histopathological examinations.The proportions of TBS I category,benign tumors,low-risk tumors,and malignant tumors were calculated.The proportion of TBS type Ⅰ,benign tumors,low-risk tumors,and malignant tumors was quantified.Subsequently,a comparative analysis was conducted among the benign,low-risk,and malignant groups in terms of clinical characteristics including gender distribution,nodule composition,contralateral cancer occurrence,diffuse echo changes presence,as well as TPOAB and TGAB levels.Results Seven cases in TBS I category were excluded.Among the remaining 87 cases with confirmed pathology results for nodules,there were 72 benign cases(38 cytology cases and 34 histology cases),5 low-risk thyroid tumors(2 cytology cases and 3 histology cases),10 malignant cases(8 PTC cases,1 FTC case,and 1 MTC case).There was a significant difference in nodule ingredient(cystic/solid)between different pathological types(x2=10.369,P=0.006).However,no statistical significance was found in terms of gender,diffuse echo changes,contralateral cancer presence,TPOAB or TGAB(P＞0.05).Further analysis showed that the proportion of solid component was higher in low-risk tumors than in benign nodules(x2=9.571,P=0.002).No statistical significance was found between malignant nodules and low-risk nodules(x2=2.143,P=0.143),or between malignant nodules and benign nodules(x2=2.165,P=0.141).Conclusion Although TI-RADS 3 nodules are generally considered as potentially benign according to various versions of thyroid imaging reporting and data system,malignant nodules still account for a certain proportion.Attention should be paid to thyroid nodules with a typical ultrasonic signs,such as cystic nodules,thyroid follicular tumors and medullary thyroid carcinoma.Ultrasound guided fine needle aspiration cytopathology is necessary for evaluating benign and malignant nodules.It is necessary to pay attention to unsatisfactory or undiagnosable specimens to improve the accuracy of diagnosis.

Objectives:To explore the changes of some peripheral blood cells related to inflammation in patients with non-arteritis central retinal artery occlusion (NA-CRAO).Methods:A retrospective clinical study. From July 2019 to July 2021, a total of 218 patients with NA-CRAO hospitalized (NA-CRAO group) in Department of Ophthalmology, Xi'an People's Hospital (Xi'an Fourth Hospital) and 218 patients with routine physical examination (control group) during the same period were included in the study. There were no significant differences in age ( t=0.60), sex composition ratio ( χ2=0.83) and body mass index ( t=0.77) between the two groups ( P>0.05). 0.2 ml fasting peripheral blood was collected from the subject, and white blood cells (WBC), neutrophils (NEUT), lymphocytes (LYMPH), red blood cells (RBC), RBC distribution width (RDW), platelets (PLT), mean PLT volume (MPV), and large PLT ratio (PLCR) were detected. The NEUT/LYMPH ratio (NLR) and PLT/LYMPH ratio (PLR) were calculated. t test was used to compare measurement data between groups. Multiple logistic regression analysis was performed for blood cells with P <0.05. The receiver operating characteristic curve (ROC curve) was used to calculate the area under the curve (AUC) and 95% confidence interval (95% CI) of each inflammatory indicator, and the optimal cutoff value was determined according to the Jorden index (sensitivity+specificity-1). Results:Compared with control group, WBC, NEUT, NLR, RDW, PLR were increased in NA-CRAO group, while RBC and LYMPH were decreased, with statistical significance ( t=9.68, 12.43, 9.47, 3.64, 5.54, 5.18, 0.46; P<0.001). There was no significant difference in PLT, MPV and PLCR between the two groups ( t=0.32, 1.56, 0.84; P>0.05). Multivariate logistic regression analysis showed that NLR was a possible risk factor for the occurrence of NA-CRAO (odds ratio=2.51, 95% CI 0.780-0.859, P=0.031). ROC curve analysis showed that the AUC predicted by NLR was 0.819, the optimal critical value was 3.05, and the sensitivity and specificity were 59.2% and 92.7%, respectively. Conclusions:In peripheral blood cells of NA-CRAO patients, NEUT is significantly increased and LYMPH is decreased. NLR is a possible risk factor for NA-CRAO.

Objective:To observe the clinical and imaging features of non-arteriotic central retinal artery occlusion (NA-CRAO) with internal boundary membrane detachment (ILMD), and to analyze its relationship with visual prognosis.Methods:A retrospective clinical study. A total of 88 patients with NA-CRAO hospitalized in Department of Ophtalmology, Xi'an People's Hospital (Xi'an Fourth Hospital) from January 2014 to June 2023 were included in the study. Best corrected visual acuity (BCVA), optical coherence tomography (OCT) and fluorescein fundus angiography (FFA) were performed. The BCVA test used the international standard visual acuity chart, which was statistically converted to the logarithm of the minimum angle of resolution (logMAR) visual acuity. OCT observed the presence of ILMD and the thickening of the inner retina and the disappearance of anatomical stratification. FFA recorded arm-retinal circulation time (A-Rct) and retinal arterion-distal filling time (FT), and observed ciliary retinal artery, fluorescein retrograde filling, cotton spots, luciferin nodal filling, macular non-perfusion, capillary fluorescein leakage, optic disc strong fluorescence, choroidal background weak fluorescence and other characteristics. According to whether there was ILMD, the patients were divided into ILMD group and non-ILMD group, with 44 cases and 44 eyes respectively. The two groups received the same treatment. The follow-up time was 30 days after treatment. The clinical, FFA characteristics and BCVA before and after treatment were compared between the two groups. t-test was used for comparison between groups. Results:In ILMD group and non-ILMD group, there were 43 cases of male and 1 case of female, respectively, and the proportion of male was significantly higher than that of female. Before and after treatment, the logMAR BCVA of ILMD group and non-ILMD group were 2.35±0.42, 2.01±0.46, 1.47±0.60, 0.77±0.49, respectively. There were significant differences in logMAR BCVA between the two groups before and after treatment ( t=8.025, 12.358; P<0.001). Before treatment, A-Rct and FT in ILMD group were longer than those in non-ILMD group, and the difference was statistically significant ( t=3.052, 3.385; P<0.05). After treatment, there was no significant difference ( t=1.040, 1.447; P >0.05). The proportion of ciliary retinal artery and cotton plaque in ILMD group was lower than that in non-ILMD group. There was no significant difference in ciliary retinal artery between the two groups ( χ2=-0.961, P>0.05), but there was a significant difference in cotton wool plaque between the two groups ( χ2=-3.364, P <0.05). Compared to the non-ILMD group, The proportion of retrograde fluorescein filling in retinal artery ( χ2=-2.846), segment filling ( χ2=-3.907), macular non-perfusion ( χ2=-6.656), capillary fluorescein leakage ( χ2=-4.367), optic disc strong fluorescence ( χ2=-3.525) and choroidal background weak fluorescence ( χ2=-2.276) increased, the difference was statistically significant ( P<0.05). Conclusions:In patients with NA-CRAO, compared with those without ILMD, those with ILMD have more severe retinal ischemia and worse BCVA before and after treatment. ILMD is one of the poor prognostic markers of NA-CRAO vision.

Objective:To investigate the effects of TRIB3 activation of Wnt/β-catenin signaling pathway on the growth and pro-liferation of laryngeal carcinoma TU686 cells in vitro and expression of peripheral immunosuppressive molecules in transplanted mice.Methods:Protein and RNA expressions of TRIB3 were detected in vitro cells(human immortalized epidermal cell line HaCat and laryngeal carcinoma cell line TU686)and tissues(laryngeal carcinoma and adjacent tissues),respectively.Laryngeal carcinoma TU686 cells were cultured in vitro and divided into negative control group(NC group)and TRIB3 knockdown group(sh-TRIB3 group),total protein and RNA of cells were extracted to verify the expression level of TRIB3 in two groups.After successful verifica-tion,proliferation ability of TU686 cells was detected by CCK-8,colony cloning and flow cytometry.Protein expression levels of Wnt,Cyclin-D1,C-myc,β-catenin and p-β-catenin in two groups were detected by Western blot.Correlation analysis verified the correla-tion between TRIB3 and Wnt,Cyclin-D1,C-myc,β-catenin,p-β-catenin protein expressions.TRIB3-low expressing nude mouse transplanted tumor model(TRIB3 sgRNA group)was constructed by knockdown the TRIB3 core plasmid,and a parallel control group(Control sgRNA group)was set up,tumor growth volume and weight were observed,and serum immunosuppressive molecules expres-sions was determined by ELISA.Results:Compared with HaCat cells and normal paracarcinoma tissues,TRIB3 was highly expressed in TU686 cells and laryngeal carcinoma tissues.Compared with negative control group,proliferation ability of TU686 cells was signifi-cantly inhibited after TRIB3 knockdown,and cell growth was blocked in G1/S phase.Expressions of Wnt,Cyclin-D1,C-myc andβ-catenin protein in Wnt/β-catenin signaling pathway were decreased significantly,while expression of p-β-catenin was increased significantly.TRIB3 was significantly correlated with protein expression levels of Wnt,Cyclin-D1,β-catenin and p-β-catenin.The in vivo results showed that compared with Control sgRNA group,tumor growth volume and weight of mice in TRIB3 sgRNA group were significantly decreased,and expressions of serum immunosuppressive molecules IL-4,IL-6,IL-10,TGF-β and PGE2 were signifi-cantly decreased.Conclusion:TRIB3 is highly expressed in TU686 cells,and TRIB3 can inhibit growth and proliferation of TU686 cells and transplanted tumors by activating Wnt/β-catenin-related signaling pathways,and reverse tumor immunosuppressive microen-vironment,suggesting that TRIB3 may be an effective target for laryngeal cancer.

Objective:To compare the restoration effects and mechanical reconstruction between different approaches in percutaneous kyphoplasty (PKP) through an in vitro mechanical experiment. Methods:T 7 to L 4 segments of adult male embalmed spinal specimens were selected for this experiment. Single vertebral specimens were randomly divided into 4 groups: unilateral angled approach group (Group A), unilateral transpedicular approach group (Group B), unilateral oblique approach group (Group C), and bilateral transpedicular approach group (Group D) ( n=10). The anterior and posterior edges of the vertebral body were measured, and the vertebral volumes were calculated and compared. After the model of osteoporotic vertebral compression fracture (OVCF) was established on a biomechanical machine, the anterior and posterior edges of the vertebral body were measured again. After the 4 groups of specimens were subjected to PKP via different approaches, Micro-CT examination of the vertebral bodies was conducted to measure the postoperative anterior and posterior edges of the vertebral body. The original strength and stiffness of the vertebral body, the stiffness after modeling, the postoperative strength, the postoperative stiffness on the puncture and contralateral sides, and postoperative overall stiffness were recorded. The distribution of bone cement in the vertebral body, recovery of anterior and posterior heights, strength, and stiffness were compared among the 4 groups. Results:There was no statistically significant difference in the vertebral volume among the 4 groups ( P>0.05). The amount of bone cement in group D was significantly larger than that in the other 3 groups ( P<0.05). There was no statistically significant difference among the 4 groups in terms of vertebral height recovery, original strength, original stiffness, stiffness after modeling, or postoperative overall stiffness ( P>0.05). There was no statistically significant difference between the postoperative strength and the original strength in the 4 groups ( P>0.05). The postoperative stiffness on the puncture side in the 4 groups and the postoperative stiffness on the contralateral side in groups A and D were significantly higher than those after modeling ( P<0.05), but there was no statistically significant difference in the contralateral stiffness in groups B and C between postoperation and post-modeling ( P>0.05). Conclusions:In PKP, the unilateral angled approach, unilateral transpedicular approach, unilateral oblique approach, and bilateral transpedicular approach all can effectively restore the height, strength and overall stiffness of the responsible vertebral body. The unilateral angled approach and the bilateral transpedicular approach can achieve balanced restoration of the stiffness on bilateral sides of the responsible vertebral body.

Objective:To observe the efficacy and safety of urokinase arterial thrombolysis in the treatment of central retinal artery occlusion (CRAO) at different time window.Methods:A retrospective study. From January 2014 to November 2019, 157 eyes (157 CRAO patients) in the Xi’an People's Hospital (Xi’an Fourth Hospital) were included in the study. There were 120 males and 37 females, with the average age of 54.87±12.12 years. The mean onset time was 65.66±67.44 h. All patients were tested with BCVA using international standard visual acuity chart, and the results were converted into logMAR visual acuity record. The arm-retinal circulation time (A-Rct) and the filling time (FT) of retinal arterial trunk-terminal filling time were measured by FFA. The mean logMAR BCVA was 2.44±0.46, the mean A-Rct and FT were 27.72±9.78 and 13.58±14.92 s respectively. According to the time window, the patients were divided into the onset 3-72 h group and the onset 73-240 h group, which were 115 patients and 42 patients respectively. There were no statistically significant difference between the 3-72 h group and the 73-240 h group in age, A-Rct and LogMR BCVA before treatment ( χ2=-0.197, -1.242, -8.990; P=0.844, 0.369, 0.369); the difference was statistically significant in FT comparison ( χ2=-3.652, P=0.000). Urokinase artery thrombolytic therapy was performed at different time window of 3-24 h, 25-72 h, 73-96 h, 97-120 h, 121-240 h after the onset of onset. Age and A-Rct of patients with different treatment time windows were compared, and the differences were not statistically significant ( χ2=6.588, 6.679; P=0.253, 0.246).In comparison of FT and logMAR BCVA, the difference was statistically significant ( χ2 =30.150, 71.378; P=0.000, 0.000). FFA was rechecked 24 hours after treatment, BCVA was rechecked 30 days after treatment. The changes of A-Rct, FT and BCVA before and after treatment were compared and analyzed. The occurrence of adverse reactions during and after treatment were observed. The two groups of measurement data were compared. The t test was used for those with normal distribution and χ2 test was used for those with non-normal distribution. Spearman correlation analysis was used to analyze the correlation between onset time and the difference of A-Rct, FT shortening time and logMAR BCVA after treatment. Results:At 24 h after CRAO treatment, A-Rct and FT of 157 cases were 19.64±6.50 and 6.48±7.36 s respectively, which were significantly shorter than those before treatment, and the differences were statistically significant ( χ2=-16.236, -14.703; P=0.000, 0.000). The logMAR BCVA at 30 d after treatment was 1.72±0.76, which was significantly higher than that before treatment. The difference was statistically significant ( χ2=-14.460, P=0.000). After CRAO urokinase arterial thrombolysis at different time window, there were statistically significant differences in A-Rct shortening time, FT shortening time, and logMAR BCVA difference ( χ2=12.408, 24.200, 104.388; P=0.030, 0.000, 0.000). There was no statistically significant difference between the 3-72 h group and the 73-240 h group ( χ2 =-1.042, P=0.297) in shortening time of A-Rct after treatment. The difference of FT shortening time was statistically significant ( χ2=-3.581, P=0.000). The difference of logMAR BCVA was statistically significant ( χ2=-9.905, P=0.000). The results of Spearman correlation analysis showed that there was no correlation between the onset time and the shortening time of A-Rct and FT after treatment ( rp=-0.040, -0.081; P=0.436, 0.115), and negative correlation with the logMAR BCVA difference ( rp=-0.486, P=0.000). One case of intracranial hemorrhage occurred after treatment, and it improved after dehydration to reduce cerebral edema, scavenging free radicals and brain protection. Conclusions:Urokinase arterial thrombolytic therapy is effective for CRAO within time window of 3-240 h, A-Rct, FT and LogMRA BCVA are all improved. However, with the prolongation of thrombolytic therapy time window, the therapeutic effect of urokinase arterial thrombolytic therapy is decreased. The therapeutic effect of Urokinase arterial thrombolytic therapy was better within 72 h.

Pancreatic lipase (PL), a crucial enzyme in the digestive system of mammals, has been proven as a therapeutic target to prevent and treat obesity. The purpose of this study is to evaluate and characterize the PL inhibition activities of the major constituents from Fructus Psoraleae (FP), one of the most frequently used Chinese herbs with lipid-lowering activity. To this end, a total of eleven major constituents isolated from Fructus Psoraleae have been obtained and their inhibition potentials against PL have been assayed by a fluorescence-based assay. Among all tested compounds, isobavachalcone, bavachalcone and corylifol A displayed strong inhibition on PL (IC < 10 μmol·L). Inhibition kinetic analyses demonstrated that isobavachalcone, bavachalcone and corylifol A acted as mixed inhibitors against PL-mediated 4-methylumbelliferyl oleate (4-MUO) hydrolysis, with the K values of 1.61, 3.77 and 10.16 μmol·L, respectively. Furthermore, docking simulations indicated that two chalcones (isobavachalcone and bavachalcone) could interact with the key residues located in the catalytic cavity of PL via hydrogen binding and hydrophobic interactions. Collectively, these finding provided solid evidence to support that Fructus Psoraleae contained bioactive compounds with lipid-lowering effects via targeting PL, and also suggested that the chalcones in Fructus Psoraleae could be used as ideal leading compounds to develop novel PL inhibitors.

Objective To evaluate the value of human papillomavirus (HPV) 16/18 E6 protein detection in shunting and prognosis in patients with atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intraepithelial lesions (LSIL). Methods A total of 98 patients with ASCUS or LSIL from the Affiliated Cancer Hospital of Shanxi Medical University between May 2014 and May 2015 were selected as the subjects. All of them received the thin-cytologic test (TCT), HPV DNA, HPV16/18 E6 protein tests and colposcopy examination. After 3-year follow-up of patients with cervical intraepithelial neoplasia (CIN) grade Ⅰor bellow lesions diagnosed by biopsy and 30 negative controls, the above tests were performed again. The efficacies of all the tests were analyzed. The value of CIN grade Ⅱ or above was predicted. Results The sensitivity, specificity, positive predictive value and negative predictive value in predicting CIN grade Ⅱor above lesions of HPV16/18 E6 protein , HPV DNA and HPV16/18 DNA was 30.8％, 95.3％, 50.0％, 90.0％, respectively; 84.6％, 37.6％, 17.2％, 94.1％, respectively and 61.5％, 67.1％, 22.2％, 91.9％, respectively in shunting study. The relative risk (RR) of CIN grade Ⅱor above lesions in patients with positive HPV16/18 E6 protein, persistent positive HPV16/18 DNA and positive HPV16/18 DNA was 13.429, 10.231 and 8.343, respectively in the follow-up study. Odds ratio (OR) of HPV16/18 E6 positive protein presenting persistent positive HPV16/18 DNA was 34.833 (95％ CI 5.020-241.711). Conclusions In patients with ASCUS and LSIL, the specificity and positive predictive value of HPV16/18 E6 protein in predicting CIN grade Ⅱ or above lesions are higher than those of HPV DNA and HPV16/18 DNA. Moreover, these patients with HPV16/18 E6 protein positive have a higher risk of developing CIN grade Ⅱ or above lesions and persistent positive HPV16/18 DNA.
