ObjectiveTo observe the effects of the Fuyuan Tongluo prescription （composed of Astragali Radix， Carthami Flos， Spatholobi Caulis， Liquidambaris Fructus， Lycopodii Herba， Centellae Herba， etc.） in the treatment of restenosis with collateral obstruction syndrome after interventional operation of lower limb arteriosclerosis obliterans， and its impact on the primary patency rate. MethodsA total of 88 patients with collateral obstruction syndrome after interventional surgery for lower limb arteriosclerosis obliterans were randomly divided into two groups. The control group （n₁=44） received dual antiplatelet therapy with aspirin and clopidogrel. The observation group （n₂=44） was treated with Fuyuan Tongluo prescription non-decocted granules in addition to aspirin and clopidogrel. Both groups received treatment for 24 weeks and were followed up for 36 weeks. The changes in primary patency rate， symptom scores， ankle-brachial index （ABI）， coagulation function， and inflammatory markers before and after treatment were compared between the two groups. ResultsFor primary patency rate， after 36 weeks of treatment， the observation group had a significantly better primary patency rate than the control group （χ²=4.14，P<0.05）. After 24 weeks of treatment， there was no significant difference in primary patency rate between the two groups. Clinical efficacy comparison： Based on symptom quantification scores， and using the Nimodipine method as a reference， the overall efficacy of the observation group was superior to that of the control group after 24 weeks of treatment （χ²=2.24，P<0.05）. ABI levels： The observation group had a higher ABI than the control group after 24 and 36 weeks of treatment （P<0.05）. Coagulation function indicators： After 24 and 36 weeks of treatment， D-dimer and fibrinogen levels in both groups were lower than before treatment （P<0.05）. Inflammatory markers： After 24 and 36 weeks of treatment， CRP levels in the observation group were lower than those in the control group （P<0.05）. There were no significant differences in white blood cell （WBC） and erythrocyte sedimentation rate （ESR） levels before and after treatment between the two groups. ConclusionAdding Fuyuan Tongluo prescription non-decocted granules to dual antiplatelet therapy can improve the primary patency rate of the affected vessels in patients with lower limb arteriosclerosis obliterans after interventional surgery. Longer use of Fuyuan Tongluo prescription can significantly improve clinical symptoms， demonstrating clinical application value.

Objective:To investigate the effects of improving the prenatal multidisciplinary consultation mode on the outcomes of fetuses with structural malformations.Methods:Clinical data of pregnant women attending the Prenatal Multidisciplinary Consultation Center, jointly established by the Obstetrics & Gynecology Hospital of Fudan University and the Children's Hospital of Fudan University from January 2004 to December 2019, were retrospectively collected and analyzed. In 2014, the center optimized the multidisciplinary consultation mode to achieve a more individualized approach to genetic testing based on more accurate imaging diagnosis and deeper cooperation between the obstetrics and pediatrics teams. Differences in the number of cases, structure of the diseases, genetic testing results, outcomes, and prognosis between the improved group (enrolled from January 2014 to December 2019) and the baseline group (enrolled from January 2004 to December 2013) were compared. The Chi-square test was used for statistical analysis. Results:(1) This study recruited 5 977 pregnant women, including 3 424 in the baseline group and 2 553 in the improved group. The main indications for consultation were fetal factors [97.2% (5 812/5 977)], among which congenital structural malformations accounted for 77.5% (4 503/5 812). There was a significant difference in the systematic distribution of congenital structural malformations between the two groups ( χ2=141.31, P<0.001). The proportion of malformations involving the central nervous, cardiovascular, and urinary systems ranked in the top three in both groups. (2) The percentage of women receiving genetic testing was higher in the improved group than in the baseline group [26.7% (682/2 553) vs. 15.9% (546/3 424), χ2=103.87, P<0.001] and the positive rate of genetic testing was also higher in the improved group [19.9% (136/682) vs. 9.9% (54/546). χ2=23.42, P<0.001]. (3) Among the 5 977 cases, 418 (7.0%) were lost to follow-up; 1 741 (29.1%) opted for pregnancy termination; 123 (2.2%) had intrauterine fetal death; and 3 695 (61.8%) were live births. The rate of pregnancy termination in the improved group was lower than that of the baseline group [27.7% (707/2 553) vs. 30.2% (1 034/3 424), χ2=4.45, P=0.035]. (4) In the 1 741 cases with pregnancy termination, fatal cardiovascular system malformations ( n=413, 23.7%), central nervous system malformations ( n=377, 21.7%), multiple malformations ( n=258, 14.8%), and chromosomal abnormalities ( n=162, 9.3%) were the main causes. The top five diseases leading to pregnancy termination were cleft lip and palate [59.0% (46/78)], meningocele (5/9), gastroschisis/omphalocele [49.3% (33/67)], diaphragmatic hernia [46.5% (33/71)], and skeletal malformations [40.9% (83/203)]. The rates of pregnancy termination due to gastroschisis/omphalocele, diaphragmatic hernia, and skeletal malformations in the improved group were all lower than those in the baseline group [57.4% (27/47) vs. 30.0% (6/20), χ2=4.23; 59.0% (23/39) vs. 31.3% (10/32), χ2=5.43; 51.8% (72/139) vs. 17.2% (11/64), χ2=21.72; all P<0.05]. (5) Among the 3 695 live births, 1 979 (53.6%) were delivered by cesarean section and 1 716 (46.4%) by vaginal delivery; 3 633 (98.3%) survived and 62 (1.7%) died in the neonatal period. The survival rate of newborns in the improved group was higher than that in the baseline group [98.8% (1 648/1 668) vs. 97.9% (1 985/2 027), χ2=4.23, P=0.040]. Among the 62 dead newborns, 51 (82.3%) had fatal structural or chromosomal abnormalities. (6) In the surviving neonates, 372 (10.2%) showed no abnormalities in a postnatal reexamination, and 468 (12.9%) received surgical treatment in the neonatal period. The other 2 793 cases received no treatment in the neonatal period but were followed up regularly. Conclusion:The optimized prenatal multidisciplinary consultation mode effectively reduces the rate of pregnancy termination due to non-fatal single structural malformations and increases the survival rate of newborns.

Objective:To evaluate the mid-term complication rates of the Hui-Jing one-stage procedure (lingual mucosa combined with longitudinal preputial island flap onlay urethroplasty + tubularized incised plate glansplasty)versus the classic Bracka staged surgery for children with severe hypospadias.Methods:A retrospective analysis was conducted on clinical data of 75 children with proximal hypospadias who were treated at the Seventh Medical Center of PLA General Hospital from March 2017 to June 2022. Of these patients, 31 cases (15 cases penoscrotal type and 16 cases perineal type) were underwent the Bracka two-stage surgery with a median age of 38 months (24.0, 44.5) and 44 cases underwent the Hui-Jing one-stage procedure (23 cases penoscrotal type and 21 perineal type) with a median age of 40.5 months (20.75, 90.5). The length of urethral plate defect after correction of penile curvature was (4.30±0.84)cm in the Bracka group and (4.56±0.79)cm in the Hui-Jing group, which also showed no significant difference.There was no statistically significant difference of the median age and the position of preoperative urethral opening between the two groups( P=0.47, P=0.74). The first stage of Bracka repair consists of orthoplasty and urethral bed substitution with free preputial graft. After 6 months, the urethral plate created from free graft was tabularized to form neourethra; Hui-Jing procedure group used the free lingual mucosal as urethral plate substitution, then we conducted longitudinal preputial island flap Onlay and Snodgrass phalloplasty. The incidence of postoperative urethral fistula, urethral stricture and urethral diverticulum was compared between the two groups of cases and the difference in efficacy between the two procedures was assessed. Results:Among the 75 patients included in the study, there was no statistically significant difference in age or location of urethral meatus between the Bracka and Hui-Jing groups. In Bracka group, 9 cases of urethral stricture (29.0%), 6 case of urethral fistula (19.4%), and 2 cases of urethral diverticulum (6.5%) occurred after surgery, while 12 cases of urethral fistula (27.3%) and 3 case of urethral fistula (6.8%) occurred in the Hui-Jing group. No urethral stricture occurred in Hui-Jing group. There was no statistically significant difference in overall incidence of complications between the two groups [17/31(54.8%) vs.15/44(34.1%), P=0.12]. The incidence of urethral fistula and urethral diverticulum show no significant differences between two groups(19.4% vs 27.3, P=0.61, 6.5% vs. 6.8%, P=0.13). The number of operation in Bracka group was (2.68±1.03) and the hospitalization cost was (12 984.63±3 808.15) Yuan, while the number of operation in Hui-Jing group was (1.36±0.53) and the hospitalization cost was (8 490.54±3 136.84) Yuan. Conclusions:The Hui-Jing one-stage procedure can be used for the surgical treatment of children with severe hypospadias. There is no urethral stricture happened in Hui-Jing group, while the general complication incidence and incidence of urethral fistula and diverticulum show no differences.

Objective:To evaluate postoperative calcitonin level as a prognostic marker in long-term follow-up of medullary thyroid carcinoma(MTC).Methods:Clinical data of 146 MTC cases treated at Tianjin Medical University Cancer Institute and Hospital from Jan 2011 to Dec 2019 were reviewed retrospectively. The relationship between postoperative calcitonin and disease-free survival was analyzed. According to the level of calcitonin six months after operation, patients were divided into normal level group and elevated group.Results:The median tumor size in those 146 cases was (1.78±1.22)cm, and 81 cases had lymph node metastasis. After 6 months of follow-up, 89 cases had normal calcitonin, with median tumor size of (1.63±1.20)cm, and 35 cases had lymph node metastasis . After a median follow-up of 56 months, 78 patients had normal calcitonin, 11 patients had biochemical relapse, 3 patients had structural relapse, and no patients died. 57 cases had a higher calcitonin ,median tumor size (1.97±1.22)cm, 46 cases had lymph node metastasis, 5 cases had distant metastasis, 18 cases had structural recurrence, and 7 patients died. Univariate analysis showed that lymph node metastasis, TNM stage, preoperative calcitonin, lymph node dissection and postoperative calcitonin were correlated with long-term disease-free survival (all P < 0.05). Multivariate analysis showed that postoperative calcitonin and TNM stage were an independent prognosis factor for disease-free survival in MTC patients (all P < 0.05). Conclusion:Postoperative calcitonin is a independent prognostic marker for long-term disease-free survival in MTC patients.

The discussion and research on the clinical dominant diseases of traditional Chinese medicine （TCM） have attracted increasing attention. Through approaches including modern technology， evidence-based medical methods， and multi-disciplinary treatment， we should construct a sound TCM inheritance and innovation system， establish a collaborative innovation mechanism， and integrate major research projects， striving to make breakthroughs in TCM theory， methodology， standards， and regulation system， promoting the scientific and technological progress of TCM， and thereby improving its curative effect. The China Association of Chinese Medicine （CACM） carried out a series of youth salon seminars for clinical dominant diseases in TCM， discussing and sorting out the advantages of the dominant diseases in clinical diagnosis and treatment of TCM and integrated traditional Chinese and western medicine in specific diseases or fields. Authoritative experts in the industry were invited to give comment and guidance to form a report. Centering on clinical research of dominant diseases， thematic research was carried out in the aspects of practice， human experience-based evidence， and transformation path. Through the systematic study of the dominant diseases， the advantages of TCM in different stages of disease treatment were excavated to constantly improve the prevention and treatment ability of TCM and carry forward the advancement of TCM theory and practice. At the same time， the communication and understanding between traditional Chinese and western medicine were improved， laying the foundation for the further formation of industry guidelines or consensus and comprehensive promotion. These seminars are expected to provide references for the development of policy planning， clinical diagnosis and treatment， health economy， and social services in TCM and lay the foundation for the formation of a new modern diagnosis and treatment system with Chinese characteristics.
