Agenesis of the dorsal pancreas(ADP)is an extremely rare congenital pancreatic malformation characterized by the absence or hypoplasia of the pancreatic body and tail.Its pathogenesis is closely related to abnormal embryonic development of the ventral and dorsal pancreatic buds,governed by a complex network of transcription factors,including HLXB9,HNF1B,PDX1,PTF1A,GATA4,and GATA6.The clinical spectrum of ADP is highly variable,ranging from asymptomatic cases to manifestations such as abdominal pain,diabetes mellitus,or pancreatitis.Imaging modalities-including ultrasonography,CT,magnetic resonance cholangiopancreatography,and endoscopic retrograde cholangio-pancreatography-serve as the main diagnostic tools,with characteristic findings of absent pancreatic body and tail accompanied by compensatory enlargement of the pancreatic head.ADP is frequently associated with congenital anomalies of the kidney,biliary tract,cardiovascular system,or genital organs.Management is primarily symptomatic,with insulin replacement for diabetes and pancreatic enzyme supplementation for exocrine insufficiency.Advances in genetic sequencing and stem cell research have deepened understanding of the pathogenesis,genetic background,and potential therapeutic strategies of ADP.This review summarizes current progress in embryology,genetics,clinical features,diagnosis,and treatment of ADP,aiming to improve clinical recognition and guide future investigations.

Objective To explore the diagnostic value of amide proton transfer weighted imaging(APTWI)in conjunction with prostate-specific antigen density(PSAD)for detecting clinically significant prostate cancer(csPCa)within prostate imaging reporting and data system(PI-RADS)v2.13-5 grade lesions.Methods A retrospective analysis was conducted on the clinical and imaging data of 88 patients diagnosed with PI-RADS 3-5 grade prostate lesions.There were 59 patients with prostate cancer(PCa)and 29 with benign prostate lesion(BPL).The PCa group was divided into csPCa group(44 cases)and clinically insignificant prostate cancer(ciPCa)group(15 cases)according to Gleason score(GS).Spearman rank correlation analysis was used to analyze the correlation between APTWI-related parameters and GS in PCa.Comparative analyses were conducted to identify statistical discrepancies in APTWI and prostate-specific antigen(PSA)-related parameters across various groups.Subsequently,both solitary and combined diagnostic models were developed,and the receiver operating characteristic(ROC)curve were utilized to evaluate the diagnostic efficacy.Results APTmax and APTmean were moderately positively correlated with GS(r=0.683,r=0.705,respectively),and APTmin was weakly positively correlated with GS(r=0.547).APTWI and PSA-related parameters were significantly higher in the PCa group than in the BPL group,and APTmin had the highest efficacy in diagnosing PCa[area under the curve(AUC)=0.855].APTWI and PSA-related parameters differed among the BPL,ciPCa and csPCa groups(P＜0.05).Among the groups,statistically significant differences were observed in each parameter of APTWI and PSA-related indices between the BPL group and the csPCa group,as well as between the ciPCa group and the csPCa group(P＜0.05).In contrast,only APTmin and PSAD exhibited significant differ-ences between the BPL group and the ciPCa group(P＜0.05).The results of the combined diagnosis showed that APTmin+PSAD had the highest diagnostic efficacy for diagnosing PCa(AUC=0.899),and APTmean+PSAD had the highest diagnostic efficacy for diagnosing csPCa(AUC=0.838).Conclusion In PI-RADS 3-5 grade prostate lesions,APTWI and PSA-related parameters are statisti-cally different in the BPL,ciPCa,and csPCa groups.Notably,the combination of APTmean and PSAD exhibit the highest diagnostic efficacy for csPCa.

OBJECTIVES: To investigate the medium- and long-term efficacy of percutaneous mechanical thrombectomy (PMT) combined with stent implantation for treatment of iliac vein stenosis with lower extremity deep venous thrombosis (LEDVT). METHODS: Clinical and follow-up data of 125 patients with iliac vein stenosis and LEDVT who underwent PMT and stent implantation at five hospitals in northern Zhejiang province from January 2017 to June 2021 were collected. The thrombus clearance rate, thrombus recurrence rate, patency rate of iliac vein stents and post-thrombotic syndrome (PTS) occurrence rate were documented, and safety indicators such as bleeding, death, pulmonary embolism, stent fracture and displacement were assessed. RESULTS: Among 125 patients, for clearance of limb thrombosis, there were 8 cases of grade I (6.4%), 10 cases of grade II (8.0%), and 107 cases of grade III (85.6%). Patients were followed up for a median period of 74 months. According to the Villalta score, the recurrence rates of limb thrombosis at 12, 24 and 36 months were 8.48%, 8.93% and 10.91%; the iliac vein patency rates were 91.52%, 91.07%, and 89.09%; and the incidences of PTS were 5.08%, 5.36% and 6.36%, respectively. There were no major adverse events such as death, massive pulmonary embolism or severe hepatic and renal insufficiency, and no readmission intervention events due to stent fracture or other incidence were found. CONCLUSIONS PMT combined with iliac vein stent implantation is effective for patients with iliac vein stenosis complicated by LEDVT with good medium- and long-term efficacy and safety, which is worthy of clinical application.

This paper introduces Professor SUN Shentian's clinical experience in the treatment of refractory facial paralysis with acupuncture and moxibustion. Professor SUN believes that the etiology of refractory facial paralysis is complex. Acupuncture and moxibustion treatment should be based on cortical localization, Baihui (GV20), lower 1/5 of motor area and brainstem area are selected, and repetitive transcranial acupuncture is applied. Under the ultrasonic positioning, acupuncture is performed on the starting and ending points of the mimetic muscles in different lesion sites. Combined with the TCM pathogenesis of refractory facial paralysis with deficiency of healthy qi and retention of pathogenic factors, acupuncture and moxibustion treatment takes strengthening the healthy qi and eliminating pathogenic factors as the core, and reuses the acupoints of yangming meridians (Yingxiang [LI20], Sibai [ST2], Dicang [ST4], Hegu [LI4], Zusanli [ST36], etc.) as the main acupoints to dredge the meridians. The main facial mimetic muscles and related collateral points are selected for cluster needling to dredge the collaterals. Acupuncture at Yangbai (GB14)-toward-Tongziliao (GB1), Sibai (ST2)-toward-Dicang (ST4), Dicang (ST4)-toward-Jiache (ST6) is applied and combined with the needle-sticking and lifting technique to nourishing tendons. Qihai (CV6) and Guanyuan (CV4) are selected for acupuncture before moxibustion. In addition, Professor SUN emphasizes that the three methods of kneading, acupuncture and moxibustion should be used in Yifeng (TE17), Qianzheng (Extra) and Xiaguan (ST7). Professor SUN combines TCM syndrome differentiation with modern technology, which has the advantages of accurate positioning and diverse techniques, and provides a new idea for the treatment of refractory facial paralysis.

Objective To investigate the correlation between serum soluble fibrinogen like protein 2(sFGL2)and adipocyte fatty acid-binding protein(AFABP)with the severity and prognosis of patients with chronic heart failure.Methods A total of 102 confirmed chronic heart failure patients treated in Tangshan People's Hospital(the hospital)from June 2020 to June 2022 were regarded as the disease group.They were divided into grade Ⅱ group(28 cases),grade Ⅲ group(35 cases),and grade Ⅳ group(39 cases)based on their illness severity.They were separated into MACE group(44 cases)and non MACE group(58 cases)based on their prognosis.Additionally,102 healthy individuals who came to Tangshan People's Hospital for physical examination were regarded as the control group.The levels of serum sFGL2 and AFABP in each group were compared.Logistic regression was applied to analyze the influencing factors of poor prognosis in patients.Receiver operating characteristic(ROC)curve was applied to analyze the predictive value of serum sFGL2 and AFABP levels for poor prognosis in patients.Results Compared with the control group,the serum sFGL2 level in the diseased group was greatly reduced(P＜0.05),while the AFABP level was greatly in-creased(P＜0.05).The serum sFGL2 level in grade Ⅱ group,grade Ⅲ group,and grade Ⅳ group decreased sequentially(P＜0.05),while the AFABP level increased sequentially(P＜0.05).The heart rate and sFGL2 level in the MACE group were greatly lower than those in the non MACE group(P＜0.05),while the propor-tion of atrial fibrillation and AFABP level were greatly higher than those in the non MACE group(P＜0.05).Heart rate,atrial fibrillation,and AFABP were independent risk factors for MACE in patients(P＜0.05),while sFGL2 was an independent protective factor for MACE in patients(P＜0.05).The area under the curve(AUC)of serum sFGL2 and AFABP for predicting MACE in patients was 0.842 and 0.858,respectively,the AUC of the combination of the two was 0.943,and the combined prediction of the two was better than the in-dividual prediction(Zcombined prediction-sFGL2=2.898,P=0.004;Zcombinedprediction-AFABP=2.608,P=0.009).Conclusion Ser-um sFGL2 level is down regulated and AFABP level is up regulated in patients with chronic heart failure,which are influencing factors for the occurrence of MACE.The combination of the two has higher efficacy in predicting the prognosis of the patients.

Objective:To explore the efficacy of adjusting the dose of imatinib dose in the context of therapeutic drug monitoring (TDM) in patients with gastrointestinal stromal tumors (GISTs) who are receiving adjuvant therapy after complete resection of their tumors.Methods:This was a descriptive study. Inclusion criteria were (1) complete surgical resection with a pathological diagnosis of GIST, (2) postoperative adjuvant therapy with imatinib and dosage adjustment, (3) multiple TDM of imatinib, and (4) complete clinical, pathological, and follow-up data. The data of 70 patients with GISTs treated at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology between January 2015 and December 2023 were collected retrospectively. The study cohort comprised 15 (21.4%) men and 55 (78.6%) women of median age 60 years (range: 25–82). Of the eligible patients, 49 (70.0%) were at high-risk, 14 (20.0%) at intermediate-risk, six (8.6%) at low-risk, and one (1.4%) at very low risk. Patients were followed up by the gastrointestinal stromal tumor clinic every 2–3 months and their plasma concentrations of imatinib were checked. The dose was adjusted to 300 mg/d or 200 mg/d depending on whether they had had ≥ grade III adverse reactions, and whether the first plasma concentration of imatinib was ≥ 1,500 μg/L or between the expected range of 760 μg/L–1,100 μg/L. Studied indicators included adverse reactions, quality of life before and after dose adjustment, and overall survival and recurrence-free survival (RFS) after dose adjustment.Results:Before dose adjustment, all 70 patients received 400 mg of imatinib daily, with initial TDM values of 1,900 ± 568 μg/L, for a median duration of 8.3 months. After dose adjustment, 60 patients received 300 mg daily, with a TDM of 1,216 ± 350 μg/L, whereas 10 received 200 mg daily, with a TDM of 1,023 ± 269 μg/L. The median duration of treatment after dose adjustment was 23.4 months. Compared with those whose dosages were not adjusted, the incidence of bone marrow suppression was significantly lower (74.3% [52/70] vs. 51.4% [36/70], χ 2=9.202, P=0.010); as were the incidences of edema (95.7% [67/70] vs. 50.0% [35/70], χ 2=40.526, P<0.001); skin reactions (70.0% [49/70] vs. 32.9% [23/70), χ 2=22.495, P<0.001); and gastrointestinal reactions (38.6% [27/70] vs. 10.0% [7/70], χ 2=15.899, P<0.001) in those whose dosages were adjusted. The average total scores for physical health before and after dose adjustment were 76 ± 5 and 88 ± 4, respectively; whereas the mental health scores were 75 ± 6 and 89 ± 4, respectively. The median follow-up period was 36 months (range 6–126). During the first 3 years of follow-up, five high-risk patients with non-gastric GISTs developed recurrences. The 3-year overall survival rate was 100%, and the 3-year RFS rate was 92.8%, high-risk patients having a 3-year RFS rate of 89.8%. Conclusion:The adverse reactions and quality of life of GIST patients with severe adverse reactions to adjuvant imatinib therapy after complete resection can be mitigated by appropriately reducing the dosage of imatinib under the guidance of TDM.

Endodontic diseases are a kind of chronic infectious oral disease.Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-percha.However,it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(RCT).Recent research,encompassing bacterial etiology and advanced imaging techniques,contributes to our understanding of the root canal system's anatomy intricacies and the technique sensitivity of RCT.Success in RCT hinges on factors like patients,infection severity,root canal anatomy,and treatment techniques.Therefore,improving disease management is a key issue to combat endodontic diseases and cure periapical lesions.The clinical difficulty assessment system of RCT is established based on patient conditions,tooth conditions,root canal configuration,and root canal needing retreatment,and emphasizes pre-treatment risk assessment for optimal outcomes.The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for RCT.These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.
