Objective: To report the clinical data of two patients with prostatic hyperplasia and bladder uric acid stones，so as to provide reference for clinical practice. Methods: Clinical data of two patients successfully undergoing blue laser lithotripsy in Department of Urology，Zhenba County People's Hospital were retrospectively analyzed，including clinical manifestations，surgical methods，treatment outcomes and complications. Results: Both patients sought medical care due to progressive dysuria or hematuria.B ultrasound and magnetic resonance imaging confirmed bladder calculi and prostatic hyperplasia.One patient also had large blood clots in the bladder cavity.Both patients received transurethral blue laser prostate vaporization + transurethral bladder stone holmium laser lithotripsy.The stone surface was dark yellow，with no obvious pores，fine particles or spike protrusion.Blue laser produced an “ablative” phenomenon similar to vaporization，and then stones became smaller and fragmented.The lithotripsy lasted for 11 min and 8 min，respectively.There were multiple bladder mucosal injuries due to constant drift of stones during operation.Stone composition analysis suggested uric acid stones.After 3 months of follow-up，both patients had smooth postoperative urination，good urine control，and no stone recurrence. Conclusion: Blue laser can be applied to crush uric acid stones，and the bladder mucosa should be protected during lithotripsy.

OBJECTIVE To explore the effects of multi-disciplinary comprehensive management team of tertiary hospital collaborated with the pharmacists from community health service center （hereinafter referred to as “community pharmacists”） on elderly patients with hypertension in the community. METHODS Elderly patients with hypertension from May 2020 to May 2021 in Yuhua Community Health Service Center of Nanjing were divided into control group （76 cases） and observation group （76 cases） according to the management style. The control group was treated with regular community medical services and the observation group received regular community medical services plus pharmaceutical care provided by the comprehensive management team collaborated with community pharmacists. The compliance， blood pressure control status and hypertension-related complications were compared between 2 groups before management and after 24 months of management. RESULTS After 24 months of management， the compliance and blood pressure compliance rates in both groups were higher than before management； meanwhile， the observation group was significantly higher than control group at the corresponding period （P＜0.05 or P＜ 0.01）. The blood pressure levels of both groups were significantly lower than before management， and the systolic blood pressure as well as the incidences of the whole complications and cerebrovascular injury in the observation group were significantly lower than control group at the 583867635@qq.com corresponding period （P＜0.05）. There was statistical significance in the effects of the rate of reaching the standard of blood pressure on the complications （P＜0.01）. CONCLUSIONS The hypertension management mode of comprehensive management team collaborated with community pharmacists can significantly improve the compliance and blood pressure compliance rate of elderly patients with hypertension， and reduce the incidence of hypertension-related complications.

BACKGROUND:In recent years,cervical facet joints have been paid more and more attention to the pathogenesis and surgical treatment of cervical spondylosis,but there are few anatomical studies on adult lower cervical facet joints. OBJECTIVE:To measure three-dimensional parameters of the lower cervical facet to provide a basis for the design of the lower cervical transarticular facet screw guide. METHODS:From June 2021 to June 2022,100 cases receiving cervical spine CT examination in the Affiliated Hospital of Xuzhou Medical University were selected,with 50 males and 50 females,aged 20-50 years.After screening,each image showed no cervical spinal stenosis,cervical disc herniation,obvious bone hyperplasia,infection or tumor.The sagittal inclination angle of each segment of the cervical spine facet joint and the angle between the lower cervical spine facet joint surface and the transarticular facet joint screw at the C3-7 levels were measured after 3D reconstruction.According to the measurement results of statistical analysis,a lower cervical transarticular facet screw guide was designed using CAD software. RESULTS AND CONCLUSION:The inclination angle of the cervical facet joint surface on the sagittal plane was distributed in a U-shaped shape centered on C5,and the magnitude relationship was C7>C6>C3>C4>C5.The relationship between transarticular facet screw angles on the sagittal plane was:C6/7>C5/6>C4/5>C3/4,where the angle of C3/4,C4/5 and C5/6 was close to 90°,and the angle of C6/7 exceeded 100°.By measuring the sagittal inclination angle of the cervical facet joint and the angle of the transarticular facet screw,this study designed a guide that was perpendicular to the lower cervical facet joint surface in the sagittal plane.

Objective To investigate biomechanical differences of two posterior occipitocervical internal fixation techniques for treating basilar invagination with atlantoaxial dislocation (BI-AAD). Methods Intra-articular cage + posterior occipital plate+C2 pedicle screw (Cage+C2PS+OP), and intra-articular cage+C1 lateral mass screw+C2PS (Cage+C1LMS+C2PS) models were established based on occipitocervical CT data of the BI-AAD and clinical operation scheme, and the stability of atlantoaxial joint and stress distribution characteristics of C2 endplate and implanted instruments under different motion states were analyzed. Results Compared with the Cage+C1LMS+C2PS model, the atlantoaxial range of motion ( ROM) under flexion, extension, lateral bending and axial rotation in the Cage+C2PS+OP model were reduced by 5. 26% , 33. 33% , 43. 75% , -5. 56% , and stress peak of screw-rod fixation system were reduced by 47. 81% , 60. 90% , 48. 45% , 39. 14% , respectively. Under two internal fixation modes, stresses of C2 endplate and cage were mainly distributed on the compressive side during the motion, and both the screw-bone interface and the caudal side of screw subjected to large loading. Conclusions Two internal fixation methods could provide similar stability. However, the stress concentration of screw-rod system was more obvious and the possibility of screw loosening and fracture was greater under Cage+ C1LMS+C2PS fixation.

Spinal cord injury (SCI) is a disabling and destructive central nervous system injury that has not yet been successfully treated at this stage. Three-dimensional (3D) bioprinting has become a promising method to produce more biologically complex microstructures, which fabricate living neural constructs with anatomically accurate complex geometries and spatial distributions of neural stem cells, and this is critical in the treatment of SCI. With the development of 3D printing technology and the deepening of research, neural tissue engineering research using different printing methods, bio-inks, and cells to repair SCI has achieved certain results. Although satisfactory results have not yet been achieved, they have provided novel ideas for the clinical treatment of SCI. Considering the potential impact of 3D bioprinting technology on neural studies, this review focuses on 3D bioprinting methods widely used in SCI neural tissue engineering, and the latest technological applications of bioprinting of nerve tissues for the repair of SCI are discussed. In addition to introducing the recent progress, this work also describes the existing limitations and highlights emerging possibilities and future prospects in this field.

OBJECTIVES: To investigate the effects of propofol on the proliferation and invasion of glioma U87 cells and to explore the possible anti-tumor mechanisms. METHODS: The glioma U87 cells was divided into a blank group, a positive control group, and the propofol groups (1.00, 2.00 or 5.00 mmol/L). Cell counting kit-8 (CCK-8) was used to detect cell proliferation; Transwell method was used to detect the effect of propofol on invasion and migration of U87 cells; real-time PCR was used to detect the expression of microRNA-134 (miR-134); Western blotting was used to detect the expression levels of reproduction-related protein Ki-67, invasion-related protein metalloproteinase-2 (MMP-2), metalloproteinase-9 (MMP-9) and phosphatidylinositol 3 kinase (PI3K)/protein kinase B (Akt) signaling pathway-related protein. RESULTS: Compared with the blank group, the proliferation, invasion and migration capacity of U87 cells were reduced in the positive control group and the propofol groups after 48 hours (all CONCLUSIONS Propofol can decrease the proliferation rate, and the invasion and migration abilities of U87 cells, which may be achieved by up-regulation of miR-134 and suppression of PI3K/Akt signaling pathway.

This article reviews the related literature on the reversal of multi-drug resistance in tumors by cepharanthine, and summarizes the reversal effects and mechanisms of multi-drug resistance in different tumors such as leukemia, liver cancer, ovarian cancer, breast cancer, esophageal cancer and colon cancer. Its reversal effect on multi-drug resistance of tumors is the result of a multi-channel, multi-link combination. The main mechanism is to inhibit membrane transporter function, affect enzyme transfer system, inhibit anti-apoptotic pathway activation and anti-apoptotic protein expression.

Thromboxane A2 receptors (TPs) widely distribute in different organ systems and localize both on cell membranes and in intracellular structures.TPs are the members of seven-transmembrane G-protein-coupled receptor (GPCR) super family.Historical-ly, the involvement of TPs in platelet functions has received the greatest attention .TPs have the capacity to activate different signaling cascades which regulate platelet shape change , aggregation and secretion response .Currently , anti-platelet drugs primarily act on re-ceptors and /or signaling molecules in activation pathways .The signaling transduction of TPs in platelet contributes to the investigation of the effects of extracts of traditional Chinese medicine on antiplatelet aggregation and the exploration of the action mechanisms .

Syringaresinol-4---d-glucoside (SSG), a furofuran-type lignan, was found to modulate lipid and glucose metabolism through an activity screen of lipid accumulation and glucose consumption, and was therefore considered as a promising candidate for the prevention and treatment of metabolic disorder, especially in lipid and glucose metabolic homeostasis. In this study, the effects of SSG on lipogenesis and glucose consumption in HepG2 cells and C2C12 myotubes were further investigated. Treatment with SSG significantly inhibited lipid accumulation by oil red O staining and reduced the intracellular contents of total lipid, cholesterol and triglyceride in HepG2 cells. No effect was observed on cell viability in the MTT assay at concentrations of 0.1-10 μmol/L. SSG also increased glucose consumption by HepG2 cells and glucose uptake by C2C12 myotubes. Furthermore, real-time quantitative PCR revealed that the beneficial effects were associated with the down-regulation of sterol regulatory element-binding proteins-1c, -2 (), fatty acid synthase (), acetyl CoA carboxylase () and hydroxyl methylglutaryl CoA reductase (), and up-regulation of peroxisome proliferator-activated receptors alpha and gamma (and). SSG also significantly elevated transcription activity oftested by luciferase assay. These results suggest that SSG is an effective regulator of lipogenesis and glucose consumption and might be a candidate for further research in the prevention and treatment of lipid and glucose metabolic diseases.

Increasing attention is focused on the down-regulation of miRNAs in cancer process. Nuclear receptor subfamily 2 (NR2F2, also known as COUP-TFII) is involved in the development of many types of cancers, but its role in gastric cancer remains elusive. In this experiment, oncomine and Kaplan-meier database revealed that NR2F2 was up-regulated in gastric cancer and that the high NR2F2 expression contributed to poor survival. MicroRNA-27b was targeted and down-regulated by NR2F2 in human gastric cancer tissues and cells. The ectopic expression of miR-27b inhibited gastric cancer cell proliferation and tumor growth in vitro and in vivo. Assays suggested that the overexpression of miR-27b could promote MGC-803 cells' migration and invasion and retard their metastasis to the liver. In addition, down-regulation of miR-27b enhanced GES-1 cells' proliferation and metastasis in vitro. These findings reveal that miR-27b is a tumor suppressor in gastric cancer and a biomarker for improving patients' survival.
