Objective The key points in the epithelial-mesenchymal transition ( EMT) procedure include the downregula-tion of epithelial protein (E cadherin) and the upregulation of cell activity and cell matrix generation .The aim of this study was to es-tablish a method for primary culture and identification of mouse renal tubular epithelial cells and to explore whether the activation of C3aR can induce epithelial-to-mesenchymal transition in mouse primary renal epithelial cells . Methods Murine renal tubular seg-ments were used for primary cell culture .Immunocytochemistry and immunofluorescence staining were used to identify the renal tubular epithelial cells.The experiment groups included control group , five different concentrations of C3aR agonist groups (0.1, 1, 100, 500, and 2000 ng/mL), and three different time-point groups.The mRNA levels of E-cadherin,α-smooth muscle actin (SMA) and colla-gen I in renal tubular epithelial cells were detected by Real-time PCR; the protein of E-cadherin, α-SMA were detected by Western blot.The cytoskeleton of epithelial cells was observed by phalloidin staining . Results Compared with the control group , the protein expression of E-cadherin deceased (0.950±0.901 vs 0.650±0.221) and the expression of α-SMA (1.380±0.062 vs 1.600±0.103) and collagen I increased in C3aR agonist group (500 ng/mL, after 48 hours) (P<0.05).In addition, the association between these changes and C3aR agonists was presented in a dose-and time-dependent man-ner, respectively.The cytoskeleton staining showed that treatment of renal tubular epithelial cells with C 3aR agonists induced the formation of actin stress fibers in a time-dependent manner . Conclusion The method for primary culture and identification of mouse renal tubular epithelial cells were successfully established .The activation of C3aR could induce epithelial-to-mesenchymal transition in mouse primary renal epithelial cells , which plays an essential role in the de-velopment of renal fibrosis .Moreover , this study indicated that C 3aR may become a new therapeutic target in kidney diseases .

A three-dimensional (3D) model of human anterior chamber is reconstructed to explore the effect of different corneal temperatures on the heat transfer in the chamber. Based on the optical coherence tomography imaging of the volunteers with normal anterior chamber, a 3D anterior chamber model was reconstructed by the method of UG parametric design. Numerical simulation of heat transfer and aqueous humor flow in the whole anterior chamber were analyzed by the finite volume methods at different corneal temperatures. The results showed that different corneal temperatures had obvious influence on the temperature distribution and the aqueous flow in the anterior chamber. The temperature distribution is linear and axial symmetrical around the pupillary axis. As the temperature difference increases, the symmetry becomes poorer. Aqueous floated along the warm side and sank along the cool side which forms a vortexing flow. Its velocity increased with the addition of temperature difference. Heat fluxes of cornea, lens and iris were mainly affected by the aqueous velocity. The higher the velocity, the bigger more absolute value of the above-mentioned heat fluxes became. It is practicable to perform the numerical simulation of anterior chamber by the optical coherence tomography imaging. The results are useful for studying the important effect of corneal temperature on the heat transfer and aqueous humor dynamics in the anterior chamber.

Objective To study the apoptotic changes in hepatocytes and the expression of apoptosis-associated proteins Bax and Bcl-2 in the liver tissue of a rat nonalcoholic steato-hepatitis (NASH) model, and explore the relationship between hepatocyte apoptosis and the degree of NASH pathological changes. Methods A rat model of NASH was reproduced with feeding a fat-rich diet for a period of 2, 4, 6, 8 and 12 weeks. Cells apoptosis was evaluated by TdT-mediated dUTP nick end labeling (TUNEL), and the expression of Bax and Bcl-2 proteins was detected by immunohistochemistry in rat liver tissue of control and model groups respectively. Results The number of TUNEL-positive cells was increased in the second week, peaking at the 8th week, and it was significantly correlated with steatosis and hepatic fibrosis (r=0.707 and 0.750, respectively, P0.05). The expressions of Bax and Bcl-2 proteins were mainly located in cytoplasm of hepatocytes, some of which contained lipid droplets. Bax and Bcl-2 positive cells increased gradually with the progression of NASH. In early stage of modeling, the number of Bax positive cells was greater than that of Bcl-2, but the number of the both proteins tended to be about same in the late stage of modeling. Conclusion The cell apoptosis is a main pattern of liver damage in the process of NASH, and it is closely associated with the pathological changes. Proapoptosis protein Bax and antagonisitic protein Bcl-2 might participate in the modulation of hepatocytes apoptosis in the early stage of NASH, and they also have a marked effect in the whole process of NASH.

Objective:
To investigate the prevalence of Internet addiction among primary and middle school students in Jiaxing City, so as to provide insights into the development of interventions for Internet addiction among primary and middle school students.
Methods:
A total of 1 701 students were sampled from two primary schools, two junior high schools, two senior high schools and two vocational high schools in Jiaxing City during the period between September and October, 2021, using the stratified cluster sampling method. The Internet addiction status was evaluated using the Internet Addiction Test, and the depression status was tested using the Patient Health Questionnaire-9 (PHQ-9), while the anxiety was assessed with the Generalized Anxiety Disorder Scale (GAD-7).
Results:
The participants included 783 men (46.03%) and 918 women (53.97%), and 873 rural students (51.32%) and 828 urban students (48.68%). The overall detection of Internet addiction was 6.53% among the participants, and the prevalence of moderate and severe Internet addiction was 5.88% and 0.65%, respectively. A higher prevalence of Internet addiction was detected in rural students (χ2=4.695, P<0.05), junior high school students (χ2=65.337, P<0.05), students with a poor relationship with family members (χ2=39.231, P<0.05), teachers (χ2=28.799, P<0.05) and classmates (χ2=36.341, P<0.05). The prevalence of depressive and anxiety symptoms was 23.81% and 21.52%, respectively, and the prevalence rates of depressive and anxiety symptoms were both higher among primary and middle school students with Internet addiction (68.47% and 56.76%) than among those without Internet addiction (χ2=130.556 and 87.327, both P<0.05).
Conclusion
The prevalence of Internet addiction is high among primary and middle school students living in rural areas and with poor interpersonal relationships in Jiaxing City. Students with Internet addiction are more likely to develop depressive and anxiety symptoms.

Objective To investigate the effect of penehyclidine hydrochloride ( PHC) pretreat?ment on nuclear factor erythroid 2?related factor 2∕heme oxygenase?1 ( Nrf2∕HO?1) signaling pathway in re?nal tissues of rats with rhabdomyolysis?induced acute kidney injury ( AKI) . Methods Thirty?six pathogen?free male Sprague?Dawley rats, weighing 200-220 g, were assigned into 3 groups ( n=12 each) using a random number table: control group (group C), group AKI and PHC pretreatment group (group PHC). Rhabdomyolysis was induced by intramuscular injection of 50% glycerol 10 ml∕kg in bilateral hindlimbs. PHC 0?2 mg∕kg was injected intraperitoneally at 30 min before glycerol was injected intramuscularly in group PHC. At 1 and 6 h after glycerol injection, serum was collected for determination of blood urea nitro?gen ( BUN) and creatinine ( Cr) concentrations, and bilateral kidneys were harvested for pathological ex?amination and for determination of HO?1 activity and expression of Nrf2 mRNA and HO?1 mRNA ( by quan?titative real?time polymerase chain reaction) , Nrf2 in nucleoprotein and total protein and HO?1 in total pro?tein in renal tissues ( by Western blot) . The damage to the renal tubules was scored. Results Compared with group C, the BUN and Cr concentrations in serum and renal tubular damage scores were significantly increased, the expression of Nrf2 in nucleoprotein and total protein and HO?1 in total protein was signifi?cantly up?regulated, and HO?1 activity was significantly increased in AKI and PHC groups, the expression of HO?1 mRNA was significantly up?regulated in group AKI, and the expression of Nrf2 mRNA and HO?1 mRNA was significantly up?regulated in group PHC (P<0?01 or 0?05). Compared with group AKI, the BUN and Cr concentrations in serum and renal tubular damage scores were significantly decreased, the ex?pression of Nrf2 in nucleoprotein and total protein and HO?1 in total protein was significantly up?regulated, and HO?1 activity was significantly increased in group PHC ( P<0?01 or 0?05) . Conclusion The mecha?nism by which PHC pretreatment attenuates rhabdomyolysis?induced AKI may be related to activation of Nrf2∕HO?1 signaling pathway in renal tissues of rats.
