Objective To explore the effects of physical activity(PA)on carotid intima-media thickness(CIMT)thickening in patients with type 2 diabetes mellitus(T2DM)with poor HbA1c control.Methods A total of 2505 T2DM inpatients with poor HbA1c control who visited the Endocrinology Department of the Integrated Traditional Chinese and Western Medicine Hospital Affiliated with Nanjing University of Traditional Chinese Medicine and Changzhou Second People's Hospital Affiliated with Nanjing Medical University from January 2019 to February 2022 were enrolled in this study.The patients were categorized into the mild-intensity PA(1~599 MET-min/w,n=795),moderate-intensity PA(600~1499 MET-min/w,n=1107)and high-intensity PA(≥1500 MET-min/w,n=603)based on the metabolic equivalence level(MET).Logistic regression was performed to analyze the relationship between PA and CIMT thickening.Statified analysis was used to investigate the effects of blood pressure(BP)and low-density lipoprotein cholesterol(LDL-C)target status on CIMT thickness in different PA groups.Results Restricted cubic spline plots showed a nonlinear relationship between PA levels and the risk of CIMT thickening(P<0.05).Logistic regression showed that with moderate-intensity PA as the control,while high-intensity PA was the influence factor of CIMT thickening(OR 1.581,95%CI 1.244~2.010,P<0.05).Statified analyses showed that under mild-intensity PA,using neither BP nor LDL-C on target as reference,achievement of either index and both were the influence factor of CIMT thickening.Using BP on target as reference,achievements of both indexes,achievements of neither of both indexes,and achievement of LDL-C only were the influence factor of CIMT thickening.Using LDL-C on target as reference,achievement of neither of them and achievement of BP only were the influence factor of CIMT thickening.Under high-intensity PA,achievement of both indexes was negatively associated with CIMT thickening.Conclusions Moderate-intensity PA is the recommended scheme to prevent CIMT thickening in T2DM patients whose HbA1c is not up to standard.Mild-intensity PA is not related to the risk of CIMT thickening,while high-intensity PA is positively related to the risk of CIMT thickening,and focusing on LDL-C compliance is particularly important to avoid CIMT thickening.

ObjectiveTo explore the effect and mechanism of Sishenjian on synovial lesions induced by monosodium iodoacetate (MIA) in rats with knee osteoarthritis (KOA). MethodSixty female Sprague-Dawley (SD) rats were randomly divided into the following six groups: normal group, model group, celecoxib group, and high-, medium-, and low-dose Sishenjian group. The KOA rat model was established by intra-articular injection of MIA. Celecoxib (18 mg·kg-1) and Sishenjian (14.4, 7.2, 3.6 g·kg-1) were administered by gavage according to the groups. All rats were euthanized after four weeks of continuous administration. The transverse diameter of the bilateral knee joints of rats was measured, and gross observation of the knee joint was performed. Pathological changes in knee joint synovial tissue were observed by hematoxylin-eosin (HE) staining and picrosirius red staining. Immunohistochemistry (IHC) was used to detect the expression of vascular endothelial growth factor A (VEGFA) in synovial tissue. The levels of inflammatory cytokines in the joint synovial fluid were detected by enzyme-linked immunosorbent assay (ELISA). Real-time quantitative polymerase chain reaction (Real-time PCR) and Western blot were used to detect the expression of mRNA and proteins related to the transforming growth factor-β1 (TGF-β1)/Smad2/3 pathway in knee joint synovium. ResultCompared with the normal group, the transverse diameter of the knee joint in the model group significantly increased (P<0.01). Compared with the model group, the transverse diameter of the knee joint in rats of each Sishenjian group significantly decreased (P<0.01). Compared with the normal group, the expression levels of interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) in the knee joint synovial fluid of model group significantly increased (P<0.01). Compared with the model group, the expression levels of IL-1β and TNF-α in the knee joint synovial fluid of rats in each Sishenjian group significantly decreased (P<0.01). Compared with the normal group, the expression levels of TGF-β1, Smad2/3, phosphorylation(p)-Smad2/3, type Ⅰ collagen α1 (ColⅠα1), type Ⅲ collagen α1 (ColⅢα1), VEGFA proteins and TGF-β1, Smad2/3, ColⅠα1, ColⅢα1 mRNA in knee joint synovium of model group significantly increased (P<0.01). Compared with the model group, the expression levels of TGF-β1, Smad2/3, phosphorylation (p)-Smad2/3, ColⅠα1, ColⅢα1, VEGFA proteins and TGF-β1, Smad2/3, ColⅠα1, ColⅢα1 mRNA in knee joint synovium of rats in each Sishenjian group significantly decreased (P<0.05, P<0.01). ConclusionSishenjian can inhibit synovial inflammation and angiogenesis, and may become a potential drug for treating synovial lesions in KOA by regulating the TGF-β1/Smad2/3 pathway.

10.Application of three-dimensional (3D) surgical display system in vitreoretinal surgery training
Chinese Journal of Medical Education Research 2022;21(3):309-312
At present, vitreoretinal surgery has gradually entered the era of minimally invasive surgery, and high-speed vitrectomy, micro-incision approach and wide-angle illumination have also pushed it to a higher level. Minimally invasive vitreoretinal surgery has become one of the key and difficult points in the teaching of ophthalmic microsurgery. The three-dimensional (3D) surgical display system can provide high-resolution, multi-level magnification, and stereoscopic images for surgery teachers and multiple observers at the same time, breaking the traditional "one-to-one" teaching of the main surgeon and assistant mirrors, realizing "one-to-more" and "head-up" surgery teaching, and thereby improving the teaching effect of vitreoretinal surgery.
