Objective To evaluate the protective effect of radiation protection safety education (RPSE) on patients with differentiated thyroid carcinoma (DTC) undergoing iodine-131 (¹³¹I) treatment. Methods The DTC patients who undergo ¹³¹I treatment were divided into the control group and the RPSE group using the convenience sampling method, with 142 patients in each group. Patients in the control group received routine health education, while the RPSE group received routine health education combined with RPSE. Dose equivalent rate (DER) on pillows, bed sheets, quilt covers, and household waste of patients were compared between the two groups upon discharge. Results The median (M) DERs of patients' pillows, bed sheets, quilt covers and household waste were 3.86, 3.63, 3.91 and 56.59 times higher in the control group compared with the environmental background level, respectively. The M DERs of patients' pillows, bed sheets, quilt covers were 2.23, 2.18, and 2.55 times higher in the RPSE group compared with the environmental background level, while the M DER of household waste was equivalent to the environmental background level. The DERs of patients' pillows, bed sheets, quilt covers, and household waste in the RPSE group were significantly lower than those in the control group (all P<0.001). The DERs of the above four items were lower in both male and female patients in RPSE group compared with same-gender patients in the control group (all P<0.001). The patients' DERs of the above indicators had no significant difference among different gender in both control group and RPSE group (all P>0.05), except for higher DER of household waste in female patients than that of male patients in the control group (P<0.05). There were no significant differences in the DERs of pillows, bed sheets, quilt covers, and household waste across subgroups, where patients received different treatment doses, of both the control group and the RPSE group (all P>0.05). Conclusion RPSE for DTC patients treated with ¹³¹I, reduces the DERs of pillows, bed sheets, quilt covers, and particularly household waste.

Objective To systematically evaluate the efficacy of different analgesic methods in re-lieving the pain in hip and femoral shaft fractures patients during spinal anesthesia position by using network meta-analysis.Methods The articals of randomized controlled trials(RCTs)that analgesia was performed in patients with hip and femoral shaft fractures during the spinal anesthesia position placement were retrieved from the following database from the establishment of the database to August 2022,PubMed,the Cochrane Library,Web of Science,EMbase,China Biology Medicine(CBM),CNKI,VIP,and Wanfang databases.Literature screening,data extraction and bias risk assessment were conducted by two researchers separately.Stata 17.0 and RevMan 5.3 software were used for statistical analysis.Results A total of 28 RCTs with 1 773 patients were included.The surface under the cumulative ranking(SUCRA)curve showed that and PENG block(94.4%)had the best effect on reducing the VAS pain score of placement position,followed by FIBcombinedwith IVA(83.8%)and FIB(71.1%),and PENG block(98.2%)had the best effect on reducing VAS pain score during spinal anesthesia,followed by FIB(71.1%)and FNB(55.6%),and PENG block(84.1%)had the best effect on shortening the time of spinal anesthesia operation,followed by FNB(70.7%)and FIB(68.5%),and PENG block(99.1%)had the best effect on improving the quality of positioning,followed by FIB(73.1%)and FNB(52.9%).Conclusion Nerve blocks or the combina-tion with IVA can reduce pain scores during position placement and spinal anesthesia,shorten anesthesia operation time,and improve quality of position placement in patients with hip and femoral shaft fractures.PENG block has the best analgesic effect in patients with hip or femoral shaft fractures during positioning and spinal anesthesia.

BACKGROUND:After the internal fixation of cannulated screws in femoral neck fractures,because the affected limb is often unable to bear weight in the short term and the implants with high stiffness have a stress shielding effect on the fracture end,it is easy to cause osteoporosis of the affected limb and changes in the biomechanical distribution of the proximal femur,the incidence of osteonecrosis of the femoral head is high after surgery.At present,few studies have been conducted on the biomechanical effects of osteoporosis at the proximal end of the femur occurring after femoral neck fracture surgery on femoral neck fracture treated with cannulated screws. OBJECTIVE:Using finite element analysis,to investigate the biomechanical effects of osteoporosis occurring after femoral neck fracture surgery on femoral neck fracture treated with cannulated screws and explore the role of biomechanical factors in osteonecrosis of the femoral head. METHODS:Based on the obtained CT scan data of the femur in a patient with a femoral neck fracture,a proximal femoral model for internal fixation for femoral neck fracture was established by Mimics 19.0,3-Matic,UG 11.0,Hypermesh 14.0,and Abaqus software.One finite element model of the proximal femur without osteoporosis and three finite element models of the proximal femur with osteoporosis were analyzed using Abaqus software.The stress,contact pressure,displacement peak and cloud map under different components of the four models were measured and analyzed,and the internal stress changes and distribution of the femoral head were compared and analyzed. RESULTS AND CONCLUSION:The stresses and contact pressures of the femoral head and lower anterior cannulated screws varied more with the degree of osteoporosis.The peak displacement of the four models increased slowly with the degree of osteoporosis.By one-way analysis of variance,there was no significant effect of the degree of osteoporosis on the peak stress,contact pressure,and displacement of the different components.The internal stress distribution of the femoral head changed with the degree of osteoporosis.Changes in the biomechanical environment of the proximal femur have an important impact on osteonecrosis of the femoral head.

Morita therapy has been bom for more than 100 years.Inpatient Morita therapy is highly oper-able and easy to master.It can improve many refractory neuroses through four-stage treatment.But more neuroses are treated in outpatient clinics,and Morita therapy cannot be used in hospitalized patients.Therefore,the formula-tion of expert opinions on outpatient operations is particularly important.This paper is based on domestic and for-eign references,and after many discussions by domestic Morita therapy experts,and then drew up the first version of the expert opinions on operation of outpatient Morita therapy.Meanwhile the operation rule of Morita therapy in three stages of outpatient treatment was formulated:in the etiological analysis stage,under the theoretical guidance of Morita therapy,analyze the pathogenic factors,to improve treatment compliance and reduce resistance;during the operating stage,guide patients to engage in constructive and meaningful actions,realizing the achievement of letting nature take its course principle;in the cultivating character and enriching life stage,pay attention to positive infor-mation,expanding the scope and content of actions,improving the ability to adapt to complex life,and preventing recurrence caused by insufficient abilities.It will lay a foundation for the promotion of Morita therapy in domestic outpatient clinics,so that more patients with neurosis and other psychological diseases could receive characteristic Morita therapy treatment in outpatient clinics.

The gut microbiota plays a pivotal role in the immunomodulatory and protumorigenic microenviron-ment of colorectal cancer(CRC).However,the effect of ginsenoside Rk3(Rk3)on CRC and gut microbiota remains unclear.Therefore,the purpose of this study is to explore the potential effect of Rk3 on CRC from the perspective of gut microbiota and immune regulation.Our results reveal that treatment with Rk3 significantly suppresses the formation of colon tumors,repairs intestinal barrier damage,and regulates the gut microbiota imbalance caused by CRC,including enrichment of probiotics such as Akkermansia muciniphila and Barnesiella intestinihominis,and clearance of pathogenic Desulfovibrio.Subsequent metabolomics data demonstrate that Rk3 can modulate the metabolism of amino acids and bile acids,particularly by upregulating glutamine,which has the potential to regulate the immune response.Furthermore,we elucidate the regulatory effects of Rk3 on chemokines and inflammatory factors associated with group 3 innate lymphoid cells(ILC3s)and T helper 17(Th17)signaling pathways,which inhibits the hyperactivation of the Janus kinase-signal transducer and activator of transcription 3(JAK-STAT3)signaling pathway.These results indicate that Rk3 modulates gut microbiota,regulates ILC3s immune response,and inhibits the JAK-STAT3 signaling pathway to suppress the development of colon tumors.More importantly,the results of fecal microbiota transplantation suggest that the inhibitory effect of Rk3 on colon tumors and its regulation of ILC3 immune responses are mediated by the gut microbiota.In summary,these findings emphasize that Rk3 can be utilized as a regulator of the gut microbiota for the prevention and treatment of CRC.

Diabetic nephropathy (DN) is a common kidney disease in diabetic patients. Long non-coding RNA maternally expressed gene 3 (MEG3) and microRNA (miR)-23c are reported to be implicated in DN development. Nevertheless, it is unclear that the molecular mechanism between MEG3 and miR-23c in DN remains unclear. Methods: Human mesangial cells (HMCs) were treated with high glucose (HG) to simulate the DN status in vitro. Expression of MEG3 and miR-23c was measured. Effects of MEG3 silencing on HG-stimulated HMC injury were determined. The relationship between MEG3 and miR-23c was verified by the dual-luciferase reporter and RNA immunoprecipitation assays. Results: MEG3 was overexpressed in serums from DN patients and HG-stimulated HMCs. MEG3 knockdown weakened HG-stimulated HMC proliferation, extracellular matrix (ECM) accumulation, and inflammation. MEG3 regulated lin-28 homolog B (LIN28B) expression through adsorbing miR-23c. MiR-23c inhibitor reversed MEG3 knockdown-mediated effects on HG-stimulated HMC proliferation, ECM accumulation, and inflammation. LIN28B overexpression overturned miR-23c mimic-mediated effects on HG-stimulated HMC proliferation, ECM accumulation, and inflammation. Conclusion: MEG3 regulated HMC injury via regulation of the miR-23c/LIN28B axis in DN, which can help us better understand the mechanism of DN mediated by MEG3.
