Diabetic nephropathy （DN） is one of the most common and serious microvascular complications of diabetes mellitus and represents a major cause of chronic kidney disease progression and end-stage kidney disease， thereby constituting a major public health problem that adversely affects the prognosis and quality of life of patients with diabetes mellitus. The pathogenesis and progression of DN are complex and involve multiple pathological processes， including insulin resistance， inflammation， oxidative stress， lipid deposition， podocyte injury， and renal fibrosis. Although current clinical therapies can delay the progression of DN to some extent， their effectiveness remains limited by marked interindividual variability in therapeutic response and the difficulty of fully reversing renal injury. Therefore， further elucidation of the key molecular mechanisms underlying DN and the exploration of effective therapeutic strategies are of considerable importance. In recent years， with advances in the understanding of DN pathogenesis， peroxisome proliferator-activated receptor γ （PPARγ）， an important nuclear receptor transcription factor involved in the regulation of insulin resistance， inflammation， oxidative stress， and fibrotic processes， has attracted increasing attention for its role in the development and progression of DN. Traditional Chinese medicine （TCM）， characterized by multi-component， multi-target， and multi-pathway synergistic regulation， may ameliorate pathological processes including metabolic abnormalities， inflammation， oxidative stress， lipid deposition， and renal fibrosis in DN by targeting PPARγ and its associated signaling networks. This review systematically summarizes the mechanisms by which PPARγ and its related signaling pathways regulate DN and reviews recent advances in TCM interventions targeting the PPARγ signaling pathway in DN. Such TCM interventions encompass single herbs such as Coptidis Rhizoma， active constituents such as quercetin， astragaloside Ⅳ， and trigonelline， extracts of herbs such as Plantaginis Herba and Dendrobii Nobilis Caulis， and formulas such as Huangkui capsules， Shenshuaining granules， and Mudan granules. This review aims to provide a theoretical basis for the prevention and treatment of DN with TCM.

Objective:The whole genome of one porcine sapelovirus (PSV) strain from mosquitoes captured in Weishan county, Shandong province was sequenced and analyzed its genetic characteristics.Methods:Mosquitoes collected in pigpen in Weishan county of Shandong province in 2021 were homogenized and inoculated on C6/36 and BHK21 cell lines for virus isolation. Virus RNA was extracted from the positive culture and the whole genome was sequenced by next generation sequencing. Phylogenetic analysis, similarity comparison and recombination analysis were conducted via MEGA 7.0.26, BioEdit 7.0.9.0 and Simplot 3.5.1.Results:A PSV strain 265/SD was isolated from Culex tritaeniorhynchus. The clear cytopathic effects characterized by rounding, shrinkage and detachment of cells were observed on BHK21 cells. The whole genome of this study strain was 7 558 nt in length. Phylogenetic analysis based on VP1 sequences indicated that strain 265/SD belonged to traditional genotype. Different positions of 265/SD in the VP1 and 3D phylogenetic trees suggested the recombinant potential. Similarity plot revealed the existence of recombination but the exact origins remained unknown. The similarity analysis of VP1 regions showed that strain 265/SD had low nucleotide identity (77.3%) and amino acid identity (80.3%) with another strain SD/CHN/2016 from Shandong province. Conclusions:Our data enriched the whole genome information of PSV in Shandong province and provided scientific basis for prevention and control of PSV.

Objective To assess the clinical value of cross raft screws technique in preventing postoperative collapse of tibial plateau fracture.Methods From September 2014 to November 2017,data of 14 patients with tibial plateau fracture who were treated by cross raft screws technique were retrospectively analyzed.There were 9 males and 5 females aged from 30-65 years old (average,44.4± 1.7 years).There were 8 patients that the thickness of subchondral cancellous bone measured preoperatively by CT data was less than 4 mm,and 6 patients that the thickness of subchondral cancellous bone measured intraoperatively was less than 4 mm.1/4 tubular plate was placed along the anterior rim of lateral tibial plateau,and the 3.5 mm cortical bone screws were fixed as bamboo raft from anterior to posterior through the plate.The collapse of tibial plateau after surgery were measured by CT scan after union of the fracture.The function of knee was evaluated by Rasmussen Anatomical and Functional Grading.Results The time of tubular plate procedure was 18 to 35 min (average,24.1±5.4 min).All 14 patients were successfully followed-up for 13.8±5.1 months.The height of collapse preoperatively by CT scan was 5-21 mm (average,8.00± 1.40 mm).3 days after the operation,the height between articular line and lateral articular surface was 0-2 mm (average,0.80±0.06 mm).Compared with CT data preoperatively,the collapse was corrected postoperatively that was proved by CT scan (P＜ 0.05).After the fracture was healed,according to CT data,the height between articular line and lateral articular surface was 0-2 mm (average,0.70±0.08 mm).Compared with CT data postoperatively,there was no postoperative collapse happened (P=0.466).The position and length of nails were placed appropriately.The average healing time of fracture was 3.6 months.There were no infection,nonunion and pain of tendon happened.The plate could be touched subcutaneously in 2 patients,who had no discomfort feelings.The patient's postoperative Rasmussen Anatomical Grading were 13-18 (average,16.7),including 8 cases excellent and 6 cases good.The postoperative Rasmussen Functional Grading was 18-28 (average,25.7),including 11 cases excellent and 3 cases good.Conclusion The cross raft screws technique is a good way to prevent the postoperative collapse of the lateral articular surface of tibial plateau.

Objective To explore the effect of electroacupuncture at Quchi (LI11), Zusanli (ST36) on differentiation of neural stem cells after cerebral ischemia-reperfusion in rats. Methods Thirty-six male Sprague-Dawley rats were randomly divided into sham group (n=12), model group (n=12) and electroacupuncture group (n=12). The latter two groups were occluded the left middle cerebral arteries for 90 min-utes and reperfused. The electroacupuncture group received electroacupuncture at Quchi and Zusanli acupoints for 21 days. They were evalu-ated with modified Neurological Severity Scores 7, 14 and 21 days after electroacupuncture. Their infarct volumes were tested with MRI T2WI 21 days after electroacupuncture, while the differentiation of neural stem cells was observed with double-immunopositive BrdU/Dcx and BrdU/NeuN. Results Compared with the model group, the neurological deficits score improved in the electroacupuncture group in all the time points (P<0.05). The infarct volumes decreased in the electroacupuncture group (P<0.05), with less number of BrdU+/Dcx+cells in subventricular zone (P<0.001) and more number of BrdU+/NeuN+ cells in peri-infarct cortex (P<0.001) 21 days after electroacupuncture. Conclusion Electroacupuncture at Quchi and Zusanli acupoints can improve neurological function and decrease the infarct volumes in rats after cerebral ischemia-reperfusion, which may be associated with promoting differentiation of neural stem cells to neurons.

Objective To investigate the effect of electroacupuncture (EA) at Shenting (DU24) and Baihui (DU20) acupoints on hippocampal synaptic plasticity and learning and memory function, and its possible mechanism in rats with cerebral ischemia-reperfusion. Methods Thirty-two male adult Sprague-Dawley rats were randomly divided into sham group (n=8), model group (n=8), electroacupuncture (EA) group (n=8) and non-acupoint group (n=8). The model group, EA group and non-acupoint group were performed with left middle cerebral artery occlusion (MCAO). The EA group received electroacupuncture at Shenting and Baihui, while the non-acupoint group received electroacupuncture at two fixed non-acupoints from bilateral ribs, for fourteen days. Then they were tested with Morris Water Maze test, and their synaptic structure of hippocampal neurons was observed with transmission electron microscope. The level of total LIM-domain containing protein kinase 1 (T-LIMK1) and LIM-domain containing protein kinase 1 phosphorylation (p-LIMK1) were detected with Western blotting. Results Compared with the sham group, the latency increased (t>6.789, P<0.01) and the frequence crossing platform decreased (t= 8.695, P<0.001) in the model group, while the number of synapse in hippocampal neurons decreased, and the level of T-LIMK1 (t=7.568, P< 0.01) and p-LIMK1 (t=8.874, P<0.001) decreased. Compared with the model group, the latency decreased (t>4.938, P<0.01) and the frequence crossing platform increased (t=- 7.891, P<0.001) in the EA group, while the number of synapses increased, and the level of T-LIMK1 (t=-6.473, P<0.01) and p-LIMK1 (t=-6.579, P<0.01) increased. There was no significant difference between the the non-acupoint group and the model group in all the indices (P>0.05). Conclusion Electroacupuncture at Shenting and Baihui can improve the ability of learning and memory in rats with cerebral ischemia-reperfusion, which may relate with the increase of LIMK1 phosphorylation and hippo-campal synaptic plasticity.

Objective To explore the effect of electroacupuncture on activation of microglia in peri-infarct cortex after cerebral isch-emia-reperfusion in rats. Methods 36 male Sprague-Dawley rats were randomly divided into sham group (n=12), model group (n=12) and electroacupuncture group (n=12). The latter two groups were occluded the left middle cerebral arteries with modified Longa's method for 2 hours and reperfused. The electroacupuncture group received electroacupuncture at Quchi (LI11) and Zusanli (ST36) acupoints for 3 days. The nerve cell damage in peri-infarct cortex was observed with HE staining, while the expression of ED1 was determined with immunohisto-chemical staining, and the expression of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β) and IL-6 were determined with Western blotting. Results The neurological deficits score improved significantly in the electroacupuncture group (P<0.05), with less nerve cell dam-age, less number of ED1 positive microglia (P<0.05) and less levels of TNF-α, IL-1βand IL-6 (P<0.05), compared with the model group. Conclusion The electroacupuncture at Quchi (LI11) and Zusanli (ST36) acupoints can protect brain from ischemia-reperfusion injury, which might be associated with inhibiting the microglial activation and proinflammatory response in peri-infarct cortex.
