ObjectiveTo observe the clinical efficacy and safety of Tangning Tongluo tablets in the treatment of nonproliferative diabetic retinopathy （DR）. MethodsFourteen research centers participated in this study， which spanned a time interval from September 2021 to May 2023. A total of 240 patients with nonproliferative DR were included and randomly assigned into an observation group （120 cases） and a control group （120 cases）. The observation group was treated with Tangning Tongluo tablets， and the control group with calcium dobesilate capsules. Both groups were treated for 24 consecutive weeks. The vision， DR progression rate， retinal microhemangioma， hemorrhage area， exudation area， glycosylated hemoglobin （HbA1c） level， and TCM syndrome score were assessed before and after treatment， and the safety was observed. ResultsThe vision changed in both groups after treatment （P<0.05）， and the observation group showed higher best corrected visual acuity （BCVA） than the control group （P<0.05）. The DR progression was slow with similar rates in the two groups. The fundus hemorrhage area and exudation area did not change significantly after treatment in both groups， while the observation group outperformed the control group in reducing the fundus hemorrhage area and exudation area. There was no significant difference in the number of microhemangiomas between the two groups before treatment. After treatment， the number of microhemangiomas decreased in both the observation group （Z=-1.437， P<0.05） and the control group （Z=-2.238， P<0.05）， and it showed no significant difference between the two groups. As the treatment time prolonged， the number of microhemangiomas gradually decreased in both groups. There was no significant difference in the HbA1c level between the two groups before treatment. After treatment， the decline in the HbA1c level showed no significant difference between the two groups. The TCM syndrome score did not have a statistically significant difference between the two groups before treatment. After treatment， neither the TCM syndrome score nor the response rate had significant difference between the two groups. With the extension of the treatment time， both groups showed amelioration of TCM syndrome compared with the baseline. ConclusionTangning Tongluo tablets are safe and effective in the treatment of nonproliferative DR， being capable of improving vision and reducing hemorrhage and exudation in the fundus.

BACKGROUND:The treatment of early knee osteoarthritis can be achieved through two knee preservation treatments:Unicondylar knee arthroplasty and high tibial osteotomy.However,further exploration is needed to determine whether there are differences in knee joint recovery between the two knee preservation surgeries at different stages after surgery. OBJECTIVE:To compare the efficacy and related complications of unicondylar knee arthroplasty and high tibial osteotomy in the treatment of varus osteoarthropathy of the knee,and to provide a reference for clinical decision. METHODS:A total of 103 patients with varus osteoarthritis of the knee underwent surgical treatment in the Affiliated Hospital of Nantong University from September 2018 to September 2022 were selected.Among them,86 patients were followed up for more than 1 year.According to different surgical methods,the patients were divided into unicondylar knee arthroplasty group(49 cases)and high tibial osteotomy group(37 cases).Knee function,pain,and line of force correction were evaluated before surgery,4 weeks,3 months,6 months,and 1 year after surgery in both groups.Hospital for special surgery knee score,functional score of Western Ontario and McMaster Universities Osteoarthritis Index,changes of lateral space of the knee joint,range of motion,proprioception(position sense),and postoperative activity recovery speed were evaluated comprehensively. RESULTS AND CONCLUSION:(1)There were no significant differences in preoperative hospital for special surgery knee score,Western Ontario and McMaster Universities Osteoarthritis Index score and lateral knee compartment size between the two groups.(2)The hospital for special surgery knee score of patients undergoing unicondylar knee arthroplasty was better than that of patients undergoing high tibial osteotomy within 4 weeks after surgery(P<0.05).At 3 and 6 months after surgery,compared with the improvement of the two groups,the hospital for special surgery knee score in the unicondylar knee arthroplasty group was lower than that in the high tibial osteotomy group,and the difference was significant(P<0.05).The range of motion flexion value and position perception of patients undergoing high tibial osteotomy were significantly better than those undergoing unicondylar knee arthroplasty 6 months after surgery(P<0.05).(3)The unicondylar knee arthroplasty group was better than the high tibial osteotomy group in terms of the speed of knee movement recovery(P<0.05).(4)However,there was no significant difference between the two groups in the change of hospital for special surgery knee score,range of motion,and the width of lateral knee space during 1-year follow-up.(5)All patients were followed up for more than 1 year,and no adverse complications were found during the follow-up.(6)It is indicated that the short-term effect of knee functional recovery in patients with high tibial osteotomy is better than that in patients with unicondylar knee arthroplasty,but there is no significant difference in medium-and long-term efficacy between the two kinds of surgery for medial knee arthritis.

BACKGROUND:Preliminary research by our group suggests that targeting fibroblast growth factor receptor 1(FGFR1)may be an effective strategy for treating RA. OBJECTIVE:To investigate the effects of an FGFR1 inhibitor(PD173074)on bone destruction in rats with collagen-induced arthritis. METHODS:Twenty-five female Sprague-Dawley rats were randomly divided into five groups:normal control group,model group,methotrexate group,low-dose PD173074 group,and high-dose PD173074 group.Except for the normal control group,rat models of type Ⅱ collagen-induced arthritis were made in each group.After successful modeling,rats were injected intraperitoneally with sterile PBS in the normal and model groups,1.04 mg/kg methotrexate in the methotrexate group,and 5 and 20 mg/kg in the low-dose group and high-dose PD173074 groups,once a week.After 4 weeks of drug administration,clinical symptoms and joint swelling in rats were observed.Micro-CT was used for three-dimensional reconstruction and analysis of the ankle joints.Pathological changes in the ankle joints were observed.Periarticular angiogenesis and the expression of receptor activator of nuclear factor-Κb ligand were detected.The expression levels of p-FGFR1,vascular endothelial growth factor A,and tartrate-resistant acid phosphatase in the synovial membrane were measured.Pathological changes in the liver,spleen,and kidney were observed and liver,spleen,and kidney indices were calculated. RESULTS AND CONCLUSION:PD173074 could alleviate clinical symptoms and joint swelling,delay bone loss,improve bone structure,reduce synovial invasion and cartilage bone erosion,reduce the number of periarticular osteoclasts,inhibit angiogenesis in synovial tissues,reduce the expression of receptor activator of nuclear factor-Κb ligand,and inhibit the expression of FGFR1 phosphorylated protein,tartrate-resistant acid phosphatase and vascular endothelial growth factor A.Pathologic observation of the liver,spleen and kidney in rats showed no obvious toxic side effects after PD173074 treatment.To conclude,the FGFR1 inhibitor can delay the progression of joint inflammation and bone destruction and inhibit angiogenesis in the rat model of type Ⅱ collagen-induced arthritis.The therapeutic effect of PD173074 has been preliminarily validated in the type Ⅱ collagen-induced arthritis model and may act by inhibiting FGFR1 phosphorylation,which provides a direction for the search of new therapeutic targets for rheumatoid arthritis.

BACKGROUND:Although researchers have noted that fibroblast growth factor receptor 1 shows great potential in rheumatoid arthritis bone destruction,there is a lack of reviews related to the potential mechanisms of fibroblast growth factor receptor 1 in rheumatoid arthritis bone destruction. OBJECTIVE:To comprehensively analyze the mechanism of fibroblast growth factor receptor 1 in bone destruction in rheumatoid arthritis by reviewing the relevant literature at both home and abroad. METHODS:We searched the CNKI database using the Chinese search terms"fibroblast growth factor receptor 1,rheumatoid arthritis,bone destruction,bone cells,osteoblasts,osteoclasts,chondrocytes,macrophages,synovial fibroblasts,T cells,vascular endothelial cells."PubMed database was searched using the English search terms"fibroblast growth factor receptor 1,rheumatoid arthritis,bone destruction,osteocytes,osteoblasts,osteoclasts,chondrocytes,macrophages,synovial fibroblasts,T cells,endothelial cells."The search period focused on April 1992 to January 2024.After screening the literature by reading titles,abstracts,and full texts,a total of 82 articles were finally included for review according to inclusion and exclusion criteria. RESULTS AND CONCLUSION:Fibroblast growth factor receptor 1 was found to be widely expressed in bone tissue-associated cells,including osteoblasts,osteoclasts,and osteoclasts.Fibroblast growth factor receptor 1 affects bone remodeling and homeostasis by regulating the function of these cells,as well as promoting the onset and progression of bone destruction in rheumatoid arthritis.Fibroblast growth factor receptor 1 is involved in the inflammatory response of synovial fibroblasts and macrophages and regulates angiogenesis of endothelial cells in synovial tissues.Fibroblast growth factor receptor 1 promotes bone destruction in several ways.Fibroblast growth factor receptor 1 may be a potential causative agent of bone destruction in rheumatoid arthritis and provides a reference for further research on its therapeutic targets.

Objective To explore the role of clinical pharmacists in the treatment of advanced breast cancer patients with severe myelosuppression.Methods This case report describes the diagnostic and therapeutic process of an advanced breast cancer patient who developed severe myelosuppression after applying ADC-based drug therapy.The clinical pharmacist proposed a prophylactic antimicrobial drug selection plan and medication monitoring recommendations for the patient's granulocytopenic fever after assessing the risk of infection and liver and renal function.For oncology drug-associated thrombocytopenia,when the doctor proposed to use the recombinant human thrombopoietin combined with TPO agonists in the case of the ineffectiveness of conventional treatment,the clinical pharmacist searched for the pharmacological basis of the combination regimen,the clinical studies of the efficacy and the adverse reactions to assist the physician's decision-making and provided targeted medication monitoring of the patient.Results The clinician and clinical pharmacist developed and implemented a rational treatment plan,and the patient was discharged with improvement.Conclusions Clinical pharmacists can assist physicians in optimizing individualized treatment plans through pharmacological monitoring of advanced breast cancer patients with severe myelosuppression.This collaborative treatment model can provide patients with more individualized treatment;it can also provide clinical reference to the treatments of patients with severe myelosuppression.

Objective:To study the current situation of the operating room nurses′ flourishing, and to explore the mediating role of self-compassion between forgiveness and flourishing, so as to provide a basis for improving the level of flourishing of operating room nurses.Methods:From September to November 2023, a total of 1 182 operating room nurses from 20 hospitals in Henan province were investigated by convenient sampling method. General data questionnaire, the Heartland Forgiveness Scale, Self-Compassion Scale and the Flourishing Scale were used to conduct an online cross-sectional survey. The mediating role of self-compassion in the relationship between forgiveness and flourishing was analyzed.Results:A total of 1 182 valid questionnaires were collected, including 261 males and 921 females. The age ranged from 21 to 54 (33.21 ± 5.72) years. In operating room nurses, the score of the forgiveness was (111.88 ± 18.77) points, the score of the self-compassion was (76.60 ± 10.75) points, the score of the flourishing was (43.48 ± 8.72) points. Forgiveness was positively correlated with self-warmth and flourishing ( r=0.545, 0.590, both P<0.05), forgiveness was negatively correlated with self-cold ( r=-0.365, P<0.05). The flourishing was positively correlated with self-warmth ( r=0.608, P<0.05), and negatively correlated with self-cold ( r=-0.509, P<0.05). self-warmth and self-cold played a mediating role between forgiveness and flourishing. The indirect effects of self-warmth and self-cold were 23.97% and 20.93% of the total mediating effects. Conclusions:The level of flourishing of the operating room nurses is at a relatively high level. Nurses′ forgiveness can affect their flourishing directly as well as indirectly through self-warmth and self-cold.

Objective:To assess the feasibility and efficacy of transperineal laser ablation(TPLA)with single laser fiber in treating benign prostatic obstruction(BPO).Methods:From April 2021 to March 2024,a total of 13 BPO patients were selected from Beijing Friendship Hospital.TPLA was performed using a single laser fiber,which was guided by transrectal biplane ultrasound.The single laser fiber was used to undergo TPLA under the guidance of trans-rectal dual-plane ultrasound.The intraoperative time,ablation time,energy consumption,indwelling time of catheter,and complications were observed.The postoperative 6 months was chosen as the cut-off point of follow-up,and the pre and postoperative changes of international prostate symptom score(IPSS),quality of life index(QoL),prostate volume(PV),residual urine volume(RUV)and the maximum urine flow rate(Qmax)were compared.Results:All 13 patients successfully underwent TPLA with single laser fiber.The average operation time was(55.1±18.3)min,and the average ablation time was(16.3±1.7)min,and average energy consumption was(3951.6±459.7)J,and the median value of indwelling time of catheter was 7(7,10)days.The number of postoperative complication was 2 cases,and both them belonged to Clavien-Dindo grade II complication.At the postoperative 6th month,the IPSS,QoL,PV,Qmax and RUV of all patients were improved,all of which were better than preoperative these indicators,and the differences were significant(t=12.102,-3.228,-3.181,-2.581,-2.936,P<0.05).Conclusion:The application of single laser fiber in conducting TPLA operation is feasibility at technical aspect,and it can achieve the therapeutic goals of improving patients'symptoms and enhancing their quality of life.Although its operational time is slightly longer than that of using multiple fibers simultaneously,it can effectively reduce the cost of expenditure for consumables.

Objective To compare the effects of different detector combinations of 320-row CT on the image quality and radiation dose of head CT to explore the feasibility of using a wide detector for head CT scanning.Methods Totally 100 patients underwent head CT scanning due to trauma or cerebrovascular disease at some hospital from June to August 2023 were collected prospectively and divided into group A and group B by using block randomization grouping method,with the length of the block group being 2 and 50 patients in each group.In group A,all the detectors had the widths at z-axis direction being 40×0.5 mm and head scanning was completed after multiple exposures;in group B,detector combinations with widths of 280×0.5 mm or 320×0.5 mm were chosen based on the patient's head size in the head-foot direction(z-axis direction),and head scanning was performed with a single-turn exposure.The remaining scanning and image reconstruction parameters in the two groups were kept completely consistent.The head image quality of the 2 groups was evaluated objectively and scored subjectively by 2 radiologists.The volume CT dose index(CTDIvol),dose length product(DLP)and exposure time of the 2 groups were recorded,and the effective dose(ED)was calculated.SPSS 22.0 software was used for statistical analysis.Results In terms of objective evaluation of image quality,at the level of the parietal skull group B had the CT value of gray matter,image noise and contrast to noise ratio(CNR)of the images higher than those of group A,and the differences were statistically significant(all P<0.05);at the level of the posterior skull group B had the CT values of gray and white matter,image noise and air noise lower while CNR higher than those of group A,and the differences were statistically significant(all P<0.05).In terms of subjective scoring of image quality,at the levels of parietal and posterior skull group A behaved better than group B,and the differences were statistically significant(all P<0.05).In group A 5 patients had obvious motion artifacts affecting the diagnosis and the image quality scores not higher than 2,and secondary scanning had to be carried out;In group B all the patients had no obvious motion artifacts and met the diagnosis requirements.When compared with group A Group B had the CTDIvol,DLP,ED and exposure time decreased by 17.44%,17.24%,17.48%and 85.53%,respectively,and the differences were statistically significant(all P<0.05).Conclusion A wide detector gains advantages over a 20 mm detector in image quality when 320-row CT is used for head CT scanning,with the diagnosis requirements satisfied.[Chinese Medical Equipment Journal,2025,46(4):57-62]

Objective:This study aims to explore the job preferences of county-level Centers for Disease Control and Prevention(CDC)personnel and to provide a basis for the development of effective incentive mechanisms.Methods:This study used a combination of stratified sampling and latent class sampling to investigate 1 809 respondents from 56 county-level CDCs in Shandong Province,Hubei Province,and Guizhou Province.Data were analysed using a mixed logit model and a latent class model,and willingness to pay was calculated.Results:The results of the mixed logit model showed that,all attributes and their levels had a significant influence(P<0.05),with establishment being the most important motivating factor(β=2.249).In the latent class model,respondents were divided into three categories.The main differences between the three classes were the choice of exit options and differences in preferences for job attributes.Conclusion:County-level CDC personnel preferred jobs with higher incomes,very good benefit levels,establishment,low workload,better recognition and respect from the public,more opportunities for career advancement,and abundant training opportunities.It is recommended that the total number of establishment should be rationally controlled and dynamically adjusted to balance the differences between working conditions within and outside the establishment;that a comprehensive approach should be adopted to improve both hygiene and motivation factors;and that different incentives should be adopted for different categories of CDC staff. Those who are willing to make a change should be provided with more opportunities for training and career advancement.
