Objective To investigate the value of 18F labeled prostate-specific membrane antigen(18F-PSMA)-1007 developing agent PET/CT(18F-PSMA-1007PET/CT)examination in the diagnostic evaluation and therapeutic decision of the newly diagnosed prostate cancer(PCa)and follow up after radical prostatecto-my(RP).Methods This study adopted the retrospective observational study method.A total of 68 patients receiving 18 F-PSMA-1007 PET/CT examination in this hospital from September 2022 to October 2023 were analyzed,including 36 cases of newly diagnosed PCa and 32 cases of biochemistry follow up failure after RP.A total of 30 items of clinical data were collected,including 8 items of basic clinical characteristics,7 items of pa-thology-related characteristics and 15 items of imaging characteristics.The patients clinical characteristics in the newly diagnosed PCa and biochemical failure after RP conducted the descriptive analysis.The Fisher exact probability method was used to analyze the differentiation of the SUVmax of primary lesions in different clini-cal subgroups[different tPSA levels at diagnosis,different mi-T stages,different Gleason scores at postopera-tive pathological puncture and different pathological types]in the newly diagnosed PCa group and the differ-entiation of recurrent lesion detection rates in different clinical subgroups(different tPSA in 18F-PSMA-1007 PET/CT examination,different pathological T stages,different lymph node invasion and different pathological Gleason scores in the biochemical failure after RP group.The Spearman correlation was adopted to test and analyze the correlation between the imaging features of positive lesions and tPSA.Results In the newly diag-nosed PCa group,there were 1 case of prostatic hyperplasia and 35 cases of PCa.SUVmax had no statistical differences among the primary lesions with different tPSA levels(P=0.81),different mi-T stages(P=0.70),different puncture Glleasonscores(P=0.20)and different pathological types(P=0.71).Moreover the tPSA value at diagnosis was positively correlated with the number of metastatic lesions(r=0.410,P=0.01).The clinical treatment decisions in 11 cases(31.43％)were changed according to the examination re-sults.In 9 cases of RP combined with lymph node dissection,the accuracy rate and concordance rate of 18F-PS-MA-1007 PET/CT and MRI in the lymph node detection rate all were 100％.I n the biochemical failure after RP group,the overall recurrent lesion detection rate was 71.88％(23/32),the operative area in situ recurrence(11 cases,34.38％)and bone metastasis(11 cases,34.38％)were most common.The differences of 18F-PS-MA-1007 PET/CT recurrent lesions detection rates had no statistical differences among the patients with dif-ferent tPSA levels(P=0.08),different pathological T stages(P=0.10),different postoperative pathological lymph node invasions(P=0.68)and different pathologic Gleason score in the 18F-PSMA-1007 PET/CT ex-amination.In the 18 F-PSMA-1007 PET/CT examination in the biochemical failure after RP,the tPSA value in the recurrent lesion was positively correlated with the number of recurrent lesions(r=0.48,P=0.01),SUVmax value in the recurrent lesion(r=0.46,P=0.01)and the SUVmean value(r=0.38,P=0.03).The clinical treatment decision in 18 cases(56.25％)was changed according to the examination results.Conclusion 18 F-PSMA-1007 PET/CT has good diagnostic value and efficiency for primary lesion and metastasis lesion of new-ly diagnosed PCa and recurrent foci of biochemical failure after RP.

Objective To compare the therapeutic efficacy of robot-assisted laparoscopic radical prostatectomy versus conventional laparoscopic radical prostatectomy,and analyze the factors influencing treatment outcomes.Methods A retrospective cohort study was conducted on 719 patients(total cohort)who underwent radical prostatectomy in our department from June 2002 to October 2023.According to different surgical methods,they were divided into robot-assisted laparoscopic radical prostatectomy group(robotic group,n=409)and conventional laparoscopic radical prostatectomy group(conventional group,n=310).Clinical characteristics,biochemical recurrence rates,and recovery of urinary continence at 1,3,6,and 12 months post operatively,as well as sexual function recovery at 6 and 12 months after surgery,were compared between the 2 groups.Additionally,the factors influencing biochemical recurrence and urinary continence recovery were analyzed across the entire cohort.Results In the cohort,the robot group demonstrated significantly larger proportions of pathological high T stages(≥pT3,P＜0.01),increased positive lymph node rate(P＜0.01),and greater number of dissected lymph nodes(P＜0.01)than the conventional group.There were no statistical differences between the 2 groups in terms of Gleason score,biochemical recurrence rate,or incidence and type of complications.The robot group exhibited significantly higher rates of urinary continence recovery at 1(P=0.004),3(P＜0.01),6(P=0.002)and 12 months(P=0.004)postoperatively.But no obvious difference was seen in the score of International Index of Erectile Function-5(IIEF-5)between the 2 groups at 6 and 12 months.Across the entire cohort,pathological high T stage(≥pT3,P＜0.01),high Gleason score(＞7,P=0.036),fewer lymph nodes dissected(≤ 10,P＜0.01),and positive lymph nodes(P=0.046)were independent risk factors for biochemical recurrence.Additionally,the surgical method,specifically robot-assisted laparoscopic radical prostatectomy,was identified as a significant factor influencing urinary continence recovery at 12 months postoperatively(P=0.005).Conclusion Compared to conventional laparoscopic radical prostatectomy,robot-assisted laparoscopic radical prostatectomy shows certain effect on reducing biochemical recurrence rate and enhancing recovery of urinary continence in prostate cancer patients at 1,3,6 and 12 months postoperatively.

Objective To summarize and analyze the clinical phenotypes,hereditary features and treatment and follow-up strategies of different hereditary pheochromocytoma/paragangliomas(PCC/PGL)and related syndromes.Methods Forty-four clinically diagnosed PCC/PGL patients admitted in our hospital from January 2000 to August 2022 were enrolled,and the clinical data of them and their family members were collected.Second-generation sequencing was performed on 43 patients for genetic detection,and Sanger sequencing was applied to verify the mutation of the probands and family members.Results There were 15 patients diagnosed with hereditary PCC/PGL,including 7 cases of von Hippel-Lindau(VHL)syndrome,3 cases of multiple endocrine neoplasia type 2(MEN2),and 5 cases of familial paraganglioma syndrome.Seven VHL syndrome families were diagnosed as VHL2A(c.500G＞A),VHL2B(c.239G＞T and c.444_457del),and VHL2C(c.293A＞G)according to their clinical manifestations.All probands received surgical treatment,and 2 cases of recurrent PCC and the patients with multiple renal cancer also received targeted therapy with sunitinib.Three MEN2 families carried c.1901G＞C,c.1832G＞A,and c.1901G＞A missense mutations,respectively,and were diagnosed with MEN2A clinically.All of them underwent adrenalectomy and thyroidectomy,including one for preventive thyroidectomy.Among the 5 familial paraganglioma syndrome families,4 patients carried SDHB mutations(SDHB:c.343C＞T,c.541-2A＞G,c.575G＞A,c.268C＞T)and 1 patient carried an SDHD mutation(SDHD:c.337_340del).Sporadic retroperitoneal PGL were most common.Conclusion More than 1/3 of PCC/PGL patients carry germline gene mutations,showing obvious genotype-phenotype correlation.Genetic diagnosis technology plays an important guidance role for clinical precision treatment and follow-up,and genetic counseling.

Background: Different views have been proposed on the radiofrequency treatment modes and parameters of radiofrequency thermocoagulation of the spinal dorsal root ganglion for the treatment of postherpetic neuralgia (PHN). It is urgent to identify a more effective therapy for patients with PHN. Methods: Patients who underwent radiofrequency thermocoagulation therapy for PHN were retrospectively reviewed and were divided into a radiofrequency thermocoagulation (CRF) and double neddles radiofrequency thermocoagulation (DCRF).The pain scores (numerical rating scale, NRS) were evaluated at the following time points: before the operation, 1 day, 3 months, 6 months, 1 year, and 2 years after operation. The incidence of complications and the degree of pain relief were evaluated. The in vitro ovalbumin experiment was used to indicate the effects of radiofrequency thermocoagulation. Results: Compared with the preoperative NRS scores, the postoperative NRS scores decreased significantly; the NRS scores of the DCRF group was lower than that of the CRF group at all time points from 6 months to 2 years following the operation. The total effective rate of the DCRF group was significantly higher than that of the CRF group at 2 years following the operation. The incidence of numbness in the DCRF group was higher than that noted in the CRF group. The ovalbumin experiments in vitro indicated that the effects of radiofrequency thermocoagulation were optimal when the distance between the two needles was 5 mm. Conclusions DCRF with a 5 mm spacing exhibits a longer duration and higher effective rate in the treatment of PHN and is worth promoting.

Organoid is one of the hottest areas of research in the field of stem cells, which is an organ in a dish with three-dimensional structure and physiological functions that are highly similar to organs in vivo.At present, the generation methods of lens organoids, namely the lentoid bodies, have been established and continuously developed.The double-convex transparent lentoid bodies, with refractive function and all microscopic components of natural lenses, act as reliable in vitro models of human lenses and provide convenience for studying the mechanism of lens development.Moreover, the establishment of age-related cataract and congenital cataract models based on the lentoid bodies also provides great convenience and reliability for the study of pathological mechanism of cataract and drug screening, showing broad prospects in basic research and even clinical transformation for cataract.
