OBJECTIVE To conduct a comprehensive clinical evaluation of four nucleoside （acid） analogues that have been approved and marketed in China， such as entecavir， tenofovir disoproxil fumarate， tenofovir alafenamide fumarate， and tenofovir amibufenamide. METHODS According to the Guideline for the Administration of Clinical Comprehensive Evaluation of Drugs （2021 edition， trial implementation）， a comprehensive search was conducted across databases including CNKI， Wanfang Data， VIP， PubMed， the Cochrane Library， Embase， as well as relevant official websites. Drug package inserts， guidelines， consensus statements， and relevant literature for the four drugs were collected and subjected to a comprehensive evaluation across six dimensions： safety， efficacy， cost-effectiveness， innovativeness， suitability， and accessibility. RESULTS The scores for entecavir in terms of safety， efficacy， cost-effectiveness， innovativeness， suitability， and accessibility-along with its comprehensive score-were 13， 14， 13， 10， 18， and 6， totaling 74 points. For tenofovir disoproxil fumarate， the respective scores were 13， 17， 18， 8， 18， and 7， totaling 81 points. For tenofovir alafenamide fumarate， the scores were 14， 20， 12， 8， 18， and 5， totaling 77 points. Finally， for tenofovir amibufenamide， the scores were 10.5， 17， 10， 6， 15， and 4， totaling 62.5 points. CONCLUSIONS Tenofovir disoproxil fumarate， with the highest score， is recommended as the first-line option， suitable for adults， children， and pregnant women. However， caution is warranted for potential renal impairment. Tenofovir alafenamide fumarate is recommended as a second-line alternative， particularly for individuals at high risk for bone and renal damage. Entecavir has a score similar to tenofovir alafenamide fumarate but requires dosing on an empty stomach and dose adjustment based on renal function of patients. Tenofovir amibufenamide received the lowest score and is considered a weak recommendation. The clinical application of these nucleoside （acid） analogues should be individualized based on the patient’s age， physiological status， and risk factors.

BackgroundIt has been shown that academic procrastination， cognitive emotion regulation strategies， anxiety and mobile phone dependence are closely related， but the detailed mechanism by which academic procrastination contributes to mobile phone dependence remains largely unclear and mediation analysis is currently lacking. ObjectiveTo explore the mediation role of cognitive emotion regulation strategies and anxiety in the relationship between academic procrastination and mobile phone dependence among college students， so as to provide references for the prevention and intervention of college students' mobile phone dependence. MethodsIn March 2023， 474 students from Xinjiang Normal University were selected by random sampling technique， and Mobile Phone Addiction Index （MPAI）， Procrastination Assessment Scale-Students （PASS）， Beck Anxiety Inventory （BAI） and Cognitive Emotion Regulation Questionnaire-Chinese version （CERQ-C） were used to conduct the survey. Pearson correlation analysis was adopted to examine the correlation among all variables， and Process 3.5 macro program was utilized to determine the mediation effect of cognitive emotion regulation strategies and anxiety on the relationship between academic procrastination and mobile phone dependence among college students. Results①PASS scores were positively correlated with the scores on CERQ-C negative cognitive emotion regulation strategy， BAI and MPAI （r=0.374， 0.229， 0.661， P<0.01）， CERQ-C negative cognitive emotion regulation strategy scores were positively correlated with BAI and MPAI scores （r=0.372， 0.498， P<0.01）， and BAI scores were positively correlated with MPAI scores （r=0.340， P<0.01）. ② Both negative cognitive emotion regulation strategy and anxiety exerted an mediation effect on the relationship between academic procrastination and mobile phone dependence among college students， with an effect value of 0.094 （95% CI： 0.056~0.137） and 0.013 （95% CI： 0.001~0.029）， and a chained mediation effect of negative cognitive emotion regulation strategy and anxiety on the relationship between academic procrastination and mobile phone dependence among college students was also documented， with an effect value of 0.015 （95% CI： 0.006~0.026）. ConclusionAcademic procrastination is proved to be effective in predicting college students' mobile phone dependence both directly and indirectly through either separate or chained mediation of negative cognitive emotion regulation strategy and anxiety. ［Funded by Social-Science Fund Project in Xinjiang （number， 2023CSH068）； Scientific Research Projects of Universities in Xinjiang Uygur Autonomous Region （number， XJEDU2023P081）］

Patients with sudden deafness encounter greater psychological challenges and communication barriers after experiencing sudden hearing loss， and traditional medical models often fail to adequately address their unique needs. This paper analyzed the current situation of emotional and behavioral changes in patients with sudden deafness， and the gap between their expectations and the reality of medical care. From the perspective of narrative medicine， the theory and characteristics of the reconstruction of the doctor-patient relationships in patients with sudden deafness were explored. The results showed that narrative medicine can enhance patients’ emotional resonance and understanding， improve the efficiency and quality of doctor-patient communication， promote the formulation of personalized treatment plans， and enhance treatment adherence and satisfaction. Based on these results， strategies and pathways for the reconstruction of doctor-patient relationships for patients with sudden deafness were proposed， including building empathetic bridges and tapping into mechanisms of emotional resonance within narrative medicine； optimizing communication strategies and promoting the application of narrative techniques in doctor-patient dialogues； connecting narrative pathways and advocating the exploration of stories and strategies in personalized treatments； as well as facilitating treatment adherence and making full use of the psychodynamic effects of narrative medicine. Narrative medicine， as a patient-centered medical practice， can effectively promote the reconstruction of doctor-patient relationships， enhance treatment effectiveness， and offer a more humane treatment experience for patients.

Objective:To summarize the clinical, pathological, and molecular genetic features of dermatofibrosarcoma protuberans (DFSP) in children.Methods:A retrospective analysis was conducted on clinical data from 8 children with DFSP in the Department of Dermatology, Beijing Children′s Hospital, Capital Medical University from January 2017 to December 2024. General information, clinical manifestations, pathological examinations, molecular genetic examinations, and treatments were analyzed, and clinical features and prognosis were summarized.Results:All the 8 cases were females, with ages at onset ( M[ Q1, Q3]) of 1.3 (0.3, 2.6) years, including 2 congenital cases; their ages at diagnosis were 5.1 (3.7, 7.4) years. Skin lesions manifested as solitary dark red patches, plaques, or nodules, and were located on the trunk in 5 cases (3 on the back, 1 on the abdomen, and 1 on the chest) and on the lower limbs in 3 cases. Histopathological examinations of all the 8 cases showed tumor cells diffusely infiltrating the dermis and subcutaneous tissue without epidermal involvement. Immunohistochemical staining showed that all the cases were strongly positive for CD34 and negative for soluble 100 protein; the Ki-67 labeling index ( M[ Q1, Q3]) was 9.0% (8.0%, 17.5%). Fluorescence in situ hybridization revealed the COL1A1-PDGFB fusion gene or PDGFB gene rearrangement in all 8 cases. All the patients underwent surgical excision of the primary skin lesions, including 3 treated with wide local excision, 2 with traditional Mohs surgery, and 3 with modified slow Mohs surgery, and all achieved negative margins. During the follow up of 6 months to 7 years, no tumor recurrence was observed. Conclusions:DFSP often occurred at a relatively young age in children, and mostly presented as atrophic patches or plaques. PDGFB gene alterations were commonly observed, and prognosis after surgical treatment was generally favorable.

Objective:To understand the basic situation of occupational internal exposure to 131I among nuclear medicine staff in Jiangsu province, and to analyze the relevant factors that contribute to the formation of internal exposure. Methods:A four-year external direct measurement of thyroid organ counting was conducted on nuclear medicine staff who underwent 131I treatment in Jiangsu province. The result were statistically analyzed, and the effective dose of accumulated internal exposure was estimated. The relationship between the detection rate of internal exposure and 10 possible factors was analyzed. Results:A total of 847 person-times were monitored during the monitoring period, of which 345 person-times were detected for 131I, with a detection rate of 40.7%. The highest individual monitoring result for internal exposure was 24.83 kBq, with an average value of 77.3 Bq and a median of 28.3 Bq among the detected individuals. The average committed effective dose of internal exposure for staff was 0.201 mSv, with a median of 0.074 mSv among the detected individuals. Conclusions:There is statistically significant difference in the detection rate of individual doses of internal exposure among nuclear medicine staff in each year. It has been observed that the main factors related to the detection rate are age, hospital grade, job position, location, whether there is an automatic dispensing operation, operating method, exposure level and length of exposure. Sufficient attention should be given to the situation of internal exposure, and further effective monitoring should be conducted on all such staff members.

Objective:To investigate the basic situation of occupational internal exposure to 131I among staff in the nuclear medicine department. Methods:Direct in- vitro measurements of thyroid doses from internal exposure were conducted for six months on 36 staff members of a hospital′s nuclear medicine department in Nanjing using the ORTEC Detective-100 portable high-purity germanium (HPGe) spectrometer. The cumulative effective doses were estimated, and the distribution of internal doses and their relationship with job type and external doses were analyzed. Results:During the monitoring period, a total of 203 monitorings were made. Of the monitoring result, 85.7% were below the recording level. Of the result exceeding the recording level, 12.8% were below the investigation level, while 1.5% exceeded the investigation level. The highest personal internal dose during the monitoring period was 2.54 mSv, the lowest was 0.015 mSv, and the median was 0.094 mSv.Conclusions:During the monitoring period, 14.3% of the monitored staff had result above the recorded levels. In the working environment of radionuclide treatment, there is no significant difference in the internal dose received between doctors, nurses, technicians, or other relevant personnel.

Objective:To explore the clinical efficacy of a free superficial palmar branch of the radial artery (SPBRA)-pedicled wrist crease flap for bridging and repairing finger C-shape soft tissue defect.Methods:From March 2021 to January 2023, the clinical data of patients with finger C-shape soft tissue defects in Department of Orthopedics, the Affiliated Changzhou No. 2 People’s Hospital of Nanjing Medical University were retrospectively analyzed. Preoperatively, color Doppler was used to locate the perforator point, and the position and size of the flap were designed. A free SPBRA-pedicled wrist crease flap was used in a Flow-through method to bridge and repair the defects. Postoperatively, the survival, color, texture, sense, and shape of the skin flap were observe, and the healing of the donor site was assessed. The clinical efficacy was evaluated using Evaluation Trail Standards for Replantation Function of Chinese Society of Hand Surgery.Results:All 10 patients completed the entry result analysis, including 8 males and 2 females. The age ranged from 22 to 54 years old. Among them, 3 cases involved the index finger, 5 cases involved the middle finger, and 2 cases involved the ring finger. All of them showed segmental defects of the unilateral volar medial artery with combined digital nerve defects, including 7 cases of radial injury and 3 cases of ulnar injury. 3 cases of the vascular defect ranged in the proximal phalanx areas, 6 cases in the middle phalanx region, and 1 case in the middle to distal phalanx region. The length of the proper artery defect ranged from 1.0 cm to 1.8 cm, the area of skin defect ranged from 1.0 cm×2.5 cm to 2.2 cm×4.0 cm, and the harvested flap area range ranged from 1.2 cm×2.8 cm to 2.5 cm×5.0 cm. The patients were followed up for 10 to 19 months. All flaps survived and healed well, with no bulky appearance, and a texture similar to normal finger skin. The static two-point discrimination ranged from 7.0~ 10.0 mm (average 8.5 mm). Superficial infection around the flap occurred in 1 case after surgery. It improved after dressing change. No vascular crisis occurred. The wounds at the donor site healed primarily, leaving linear scars. The flexion and extension activities of the wrist joint were not affected. According to the Evaluation Trail Standards for Replantation Function of Chinese Society of Hand Surgery: 8 cases received excellent results, 2 cases were good, and the patient satisfaction was high.Conclusion:The free SPBRA-pedicled wrist crease flap has good and accurate efficacy in bridging and repairing finger C-shape soft tissue defects. It has the advantages of convenient harvesting, minimal trauma, and low complication rate, and has clinical promotion and application value.

Objective To explore the factors predicting the reliability of platelet-impedance(PLT-I)re-sults through a retrospective analysis of non-aggregated samples with abnormal platelet histograms.Methods A total of 322 samples with abnormal platelet histograms were collected from the Sysmex XN9000 automatic hematology analyzer,all of which showed no platelet aggregation as determined by the DI-60 auto-matic digital image analysis system.Using the platelet count fluorescent(PLT-F)results as a standard,the absolute and relative deviations of PLT-I results were calculated,and the parameters of samples with devia-tions within and outside the allowable range were analyzed.Logistic regression analysis was used to identify potential factors associated with deviations of PLT-I from PLT-F beyond the allowable range.The receiver op-erating characteristic(ROC)curve was used to evaluate the predictive value of these potential factors for devi-ations beyond the allowable range.Results The deviations of PLT-I from PLT-F were within the allowable range in 279 cases(86.65％)and outside the allowable range in 43 cases(13.35％).Comparisons between the two groups revealed statistically significant differences in mean red blood cell valume(MCV),red blood cell distribution width-cuefficient of variation(RDW-SD),DI-60 red cell fragments,platelet distribution width(PDW),and DI-60 large platelet ratio(P＜0.05).Logistic regression indicated that DI-60 red cell fragments and DI-60 large platelet ratio were independent potential factors for deviations of PLT-I from PLT-F beyond the allowable range(P＜0.05).The cut off values for predicting deviations beyond the allowable range were 1.75 for DI-60 red cell fragments and 66％for DI-60 large platelet ratio.The area under the curve(AUC)for the combined diagnosis of the two factors was 0.813,with a sensitivity of 88.4％and a specificity of 66.3％,indicating a higher predictive value than individual factors(P＜0.05).Conclusion When platelet histograms are abnormal,DI-60 large platelet ratio and DI-60 red cell fragments are independent potential factors predic-ting the reliability of PLT-I results,and their combination has a high predictive value.

OBJECTIVES: To explore the therapeutic mechanism of puerarin for alleviating synovitis in rats with collagen-induced arthritis (CIA). METHODS: In a SD rat model of CIA, we tested the effects of daily gavage of puerarin at low, moderate and high doses (10, 30, and 100 mg/kg, respectively) for 3 weeks, with tripterygium glycosides (GTW, 10 mg/kg) as the positive control, on swelling in the hind limb joints regions evaluated by arthritis index scoring. Mass fraction of the liver of the rats was calculated, and pathologies in joint synovial membrane were observed with HE staining. The expressions of transforming growth factor β‑activated kinase-1 (TAK1), Toll-like receptor 4 (TLR4), and nuclear factor kappa-Bp65 (NF‑κB p65) at the mRNA and protein levels in the synovial tissues were detected using Real-time PCR and Western blotting. RESULTS: Compared with those in the model group, the rats in GTW group and high-dose puerarin group showed significantly reduced mass fraction of the liver. Treatment with GTW and puerarin at the 3 doses all significantly alleviated plantar swelling, lowered arthritis index scores, and improved synovitis in CIA rats (P<0.05), and the effects of puerarin showed an obvious dose dependence. Both GTW and puerarin treatments significantly lowered TAK1, TLR4, and NF‑κB p65 mRNA and protein expressions in the synovium of CIA rats. CONCLUSIONS Puerarin alleviates synovium damages in CIA rats possibly by suppressing the TLR4/NF‑κB signaling pathway via downregulating TAK1 expression.
