BACKGROUND:At present, the incidence rates of knee joint diseases such as knee osteoarthritis, knee joint degenerative are high. The major clinical treatment is total knee replacement in the clinic, so it is necessary to evaluate the changes in stress and bone mineral density of the regions surrounding the prosthesis after replacement. <br> OBJECTIVE:To explore periprosthetic stress and bone mineral density and to analyze their correlation after total knee arthroplasty. <br> METHODS:A total of 20 cases undergoing total knee arthroplasty were chosen.The hospital for special surgery scores were used to evaluate patients’ functional recovery at 12 months after total knee arthroplasty. The periprosthetic femur was divided into four regions of interest (ROI), respectively ROI 1-4;periprosthetic tibia was divided into three regions of interest, respectively ROI 5-7. Stress surrounding the prosthesis was analyzed using three-dimensional finite element analysis at 1, 3, 6 months, 1, 2, 3 years after replacement. Simultaneously, bone mineral density surrounding the prosthesis was measured using dual-energy X-ray absorptiometry. <br> RESULTS AND CONCLUSION:No patients affected infection or loosening of the prosthesis. At 12 months after replacement, the score of hospital for special surgery was (90.23±2.37), which showed significant differences as compared with before replacement (39.68±1.31) (P<0.05). The level of stress shielding was highest in ROI 5 and lowest in ROI 3. Stress shielding rate of ROI increased with statistical difference at 6 months after operation (P<0.05). At 1, 2, 3 years after operation, shielding rate in periprosthetic femoral stress in ROI 1 decreased. Compared with 1 month after operation, the difference was statistical y significant (P<0.05). However, shielding rate of tibial periprosthetic stress in ROI 6 increased. Compared with 1 month after operation, the difference was statistical y significant (P<0.05). Bone mineral density after 1 month after operation had no significant decrease (P>0.05). At 3 months after operation, bone mineral density began to decline significantly (P<0.01). The decrease was most obviously in ROI 5 and the change was least in ROI 3. After 1 year of operation, bone mineral density did not change significantly. These data indicated that changes in bone mineral density were correlated with stress shielding after total knee arthroplasty. Monitoring two variations can provide theoretical data for preventing bone loss, which provides references for clinical rehabilitation guidance.

Abstract: Mosquitoes are involved in the transmission of serious diseases such as malaria, dengue, chikungunya, yellow fever, Zika virus disease, and filariasis, and their prevention and control have always been a research hotspot. Currently, mosquito control methods mainly include physical control, chemical control and biological control. Physical control methods are environmentally friendly, but they are slow to take effect and have unsatisfactory control effects; although chemical control can quickly eliminate mosquitoes, it has been eliminated due to its high pollution, high residual, and easy drug resistance; biological control uses natural enemies or pathogens to kill mosquitoes and reduce their ability to transmit disease. Therefore, environmentally friendly biological control has become the main measure for controlling and preventing mosquitoes. In recent years, significant progress has been made in bacterial mosquito control agents, among which Bacillus thuringiensis has been the most extensively studied. Bacillus thuringiensis is a Gram-positive soil microorganism, which is the pathogenic bacterium of a variety of agricultural pests such as Lepidoptera, Coleoptera and Diptera. During the sporulation process, its strains produce a variety of insecticidal crystal proteins (ICPs) or δ-endotoxins with insecticidal activity against mosquito larvae. This review firstly introduces the crystal proteins of Bacillus thuringiensis, describes in detail the types and structures of crystal proteins in detail, and also reveals the mechanism of action of crystal proteins related to receptors.

A series of isoindoline derivatives were designed, synthesized, and evaluated for their double inhibitory activities. All of them were new compounds, and their structures were confirmed by 1H NMR and HR-MS. Preliminary in vitro pharmacological tests showed that all compounds exhibited 5-HT or NE reuptake inhibition activity. Among the tested compounds, compound I-3 exhibited potent inhibitory activity against 5-HT and NE reuptake in vitro, and exhibited potent antidepressant activity in vivo. These compounds designed can be further optimized for finding more potent 5-HT/NE dual reuptake inhibitors and antidepressant candidates as well.

Objective To study the role of manganese-enhanced MRI(MEMRI) in the depiction of cortical architecture of rat brain after systemic administration of Mn~(2+) through caudal vein and compare the effects of normal or opened blood-brain barrier on the manganese-enhanced MRI. Methods Fifteen SD rats were randomly divided into three groups according to ranked list of random. Blood-brain barrier was opened in short time by the injection of 30% mannitol via the right internal carotid artery, in group A, then 100 mmol/L MnCl_2 physiologic saline solution was delivered through vena caudalis, and MRI was performed 12 hours later. In group B, 100 mmol/L MnCl_2 physiologic saline solutions was administrated through vena caudalis, following normal saline injection into the right internal carotid artery, and MRI was performed 12 hours later. The group C served as normal control group. All images were acquired with a 7.0 T microMR scanner. Signal-to-noise ratios (SNR) in regions of interest were measured by Paravision 4.0 and the differences of three groups were compared by using one-way ANOVA. The differences of SNR on both sides of hemispheres were compared by using paired t test. Results MEMRI could show the gray matter and white matter of rat brain and the anatomy borders between somatosensory cortex and motor cortex clearly. Periventricular structures such as hippocampus, dentate gyms, habenula united, and olfactory bulb could also be showed clearly. Symmetrical enhancement on both sides of the cortex and banded structures was shown clearly in group B. The SNR increased and the differences were significant in right cerebral cortex, both sides of cerebellar cortex, hippocampus and pituitary, among three groups (right cerebral cortex 35.2±7.0,30.1±2.4,26.6±2.8,F =4.36,P=0.038;left cerebellar cortex 27.1±5.2,29.4±3.8,19.4±4.5, F=6.66, P=0.011;right cerebellar cortex 27.8±3.8,28.5±4.2,20.4±4.8, F=5.84, P=0.017; left hippocampus 34.5±4.9,38.1±5.3,24.5±3.6, F=11.38, P=0.002; right hippocampus 35.3±5.5, 37.6±4.7,25.6±3.0,F=9.93,P=0.003;pituitary 39.5±3.8,52.6±9.1,26.2±4.2,F=22.80, P=0.001) after systemic administration of Mn~(2+). Asymmetric enhancement on two sides of cortex was shown in group A. The mannitol-infused side was enhanced obviously but displayed blurring banded structures. However,the SNR differences of both sides of hemispheres in group A and B were not significant (P >0.05). Conclusions After systemic administration of MnCl_2 through vena caudalis, MEMRI could map the laminar architectures and the anatomy border of functional zone of somatosensory cortex specifically. High concentration of mannitol could open blood brain barrier(BBB) effectively and have distinct impacts on the architectures displayed in MEMRI. Opening or maintaining BBB in MEMRI had respective characteristics, and it should be selected according to practical needs.
