OBJECTIVE To evaluate the long-term cost-effectiveness of insulin degludec and insulin aspart （IDegAsp） in patients with type 2 diabetes mellitus （T2DM） in China. METHODS A cost-effectiveness analysis was conducted from the perspective of the Chinese healthcare system， using the CORE diabetes model to simulate long-term （20-year） health and economic outcomes. Baseline cohort characteristics and treatment effect data were derived from the CREATE study. The prices of glucose- lowering drugs were obtained from medical insurance payment standards and the average winning bid prices in the follow-up round of the specialized centralized procurement for insulin， while the daily dosages were derived from the CREATE study. The costs of complications and utility values were obtained from published literature， with a discount rate of 5%. One-way sensitivity analysis， scenario analysis， and probabilistic sensitivity analysis were performed to verify the robustness of the results. RESULTS Patients switching from previous once-daily basal insulin regimens to IDegAsp therapy gained an incremental 0.190 quality-adjusted life year （QALY） with direct medical cost savings of 42 163.58 yuan. For those switching from premixed insulin therapies， IDegAsp treatment provided 0.130 incremental QALY and reduced direct healthcare costs by 41 129.11 yuan. The outcome was significantly influenced by the discount rate and the cost of complications. Probabilistic sensitivity analysis and scenario analysis confirmed the robustness of these findings. CONCLUSIONS Switching from previous daily basal insulin or premixed insulin regimens to IDegAsp in Chinese patients with T2DM can improve patients’ long-term health outcomes and achieve cost savings， making it a more cost-effective treatment option.

Objective:To explore the distribution characteristics of HBsAg levels in treatment-na?ve and treatment-experienced patients with chronic hepatitis B (CHB) in China.Methods:Data were obtained from the China Registry of Hepatitis B (CR-HepB) platform from the establishment of the platform to April 11, 2024. Patients with CHB who were treatment-na?ve and treatment-experienced with nucleos(t)ide analogs (NAs) were included. Relevant clinical data were collected. The distribution of hepatitis B surface antigen (HBsAg) status, as well as the levels in populations of different age groups after different antiviral treatment durations, were retrospectively analyzed. Normally and non-normally distributed measured data were represented by Mean± SD, and M( Q1, Q3). Results:A total of 13 505 treatment-na?ve patients and 6 390 treatment-experienced patients were included in the analysis. The proportions of treatment-na?ve patients with HBsAg<100, <500, and <1 500 IU/mL were 10.51%, 28.47%, and 46.85%, and the corresponding proportions of treatment-experienced patients were 12.88%, 29.84%, and 52.07%. The proportions of treatment-na?ve patients with HBsAg levels≥1 500, ≥3 000, and≥8 000 IU/mL were 53.15%, 38.17%, and 15.62%, and the corresponding proportions of treatment-experienced patients were 47.93%, 31.77%, and 10.39%. HBsAg level showed a trend of gradual decrease with the increase of antiviral treatment time. The proportion of treatment-experienced patients with HBsAg<100 IU/mL increased from 12.73% when the treatment duration was less than three years to 26.92% when the treatment duration was≥10 years, while the proportion of patients with HBsAg levels≥3 000 IU/mL or≥8 000 IU/mL decreased from 34.66% to 23.08% and from 12.19% to 5.77%, respectively. The proportion of patients with HBsAg<100, <500, and<1 500 IU/mL increased with age, while the proportion of patients with HBsAg≥1 500, ≥3 000, and ≥8 000 IU/mL decreased sequentially.Conclusions:The CR-HepB platform provides a basis for clarifying the serum HBsAg levels in treatment-na?ve and treatment-experienced CHB patients in China. The HBsAg status indicates that with a prolonged antiviral treatment duration, there is a gradual decline trend in HBsAg level.

Objective:To explore the efficacy and safety of the Da Vinci robotic single-port-plus-one technique in common urological surgeries in children.Methods:The data of 59 children who underwent robot-assisted single-port-plus-one laparoscopic surgery from May 2022 to November 2023 in Fuzhou University Affiliated Provincial Hospital were retrospectively analyzed. There were 44 males and 15 females, aged 36 (6, 108)months. Among them, 27 cases had ureteropelvic junction obstruction, with a preoperative anterior-posterior diameter of the renal pelvis of (31.83±6.59) mm. The American Society of Fetal Urology (SFU) grading system revealed grade Ⅲ in 8 sides and grade Ⅳ in 19 sides. Bilateral renal function showed a difference of 13.50% (7.18%, 31.06%). Additionally, 17 cases presented with vesicoureteral reflux. Preoperative voiding cystourethrogram (VCUG) indicated reflux grades Ⅲ, Ⅳ, and Ⅴ in 8, 14, and 4 sides, respectively, with a difference in bilateral renal function of 18.58% (6.04%, 28.30%). Ten cases had obstructive megaureter, with a preoperative renal pelvis diameter of (22.17±7.64)mm and a maximum ureteral diameter of (19.51±3.71)mm. The preoperative bilateral renal function difference was 18.02% (5.23%, 49.42%).Five cases involved duplicated kidney and ureter. Magnetic resonance urography (MRU) confirmed unilateral duplicated kidneys with associated dilatation of the upper renal pelvis and calyces, hydroureter, thin renal cortex in all 5 patients. Among them, 2 cases had ectopic ureteral opening and 1 case had terminal ureteral cyst. Patients with ureteropelvic junction stenosis underwent pyeloplasty, those with vesicoureteral reflux and obstructive megaureter underwent ureteral reimplantation, and patients with duplicated ureters underwent nephrectomy. The Da Vinci robotic surgical system was employed for all procedures. The port placement technique involved a 2-3 cm incision around the navel to insert a single-port four-channel device, followed by the placement of an additional 8 mm operating channel in the left or right abdomen under direct visualization based on the surgical site. Preoperative and postoperative parameters were compared.Results:All operations were successfully completed without conversion to open or laparoscopic surgery. The operation time of the ureteropelvic junction obstruction children was (141.52±22.93) min. The postoperative renal pelvis diameter and bilateral renal function difference were (12.54±4.05) mm and 5.60%(2.14%, 14.48%), respectively, both of which showed significant improvement compared to preoperative levels ( P<0.01). Postoperative hydronephrosis grades were as follows: 13 sides with grade Ⅰ, 13 sides with grade Ⅱ, and 1 side with grade Ⅲ. The operation time of vesicoureteral reflux children was (125.00±11.75) min in the unilateral group and (153.22±14.39) min in the bilateral group. Postoperatively, 2 sides demonstrated reflux grade Ⅰ, 1 side grade Ⅱ, and 1 side grade Ⅲ, indicating improvement compared to preoperative levels. Bilateral renal function difference post-surgery was 13.34% (1.85%, 20.54%), which was more balanced than preoperatively ( P=0.011). Postoperative renal pelvis anterior-posterior diameter and maximum ureteral diameter were reduced to (10.31±3.86) mm and (6.62±2.44) mm, respectively, which were significantly smaller than preoperative measurements ( P<0.01). The bilateral renal function difference post-surgery was 12.04% (4.85%, 47.53%), showing improvement, though not statistically significant ( P=0.508). The operation time of the repeated nephrectomy children was (140.00±12.75) min. No recurrence of preoperative symptoms was noted, and renal cortical function remained generally normal during follow-up. In this study, only 3 cases of obstructive megaureter developed febrile urinary tract infection within 1 month after surgery, and no complications were observed in the remaining cases. Conclusions:This study preliminarily confirmed that the Da Vinci robotic single-port-plus one-port technology can be used in the treatment of common diseases of the urinary system in children. The patients' symptoms were significantly relieved after surgery, and the indicators of hydronephrosis improved compared with those before surgery. The incidence of postoperative complications was low, and aesthetic outcomes of postoperative scars were enhanced. Further studies are needed to assess its long-term efficacy.

OBJECTIVE: To determine risk factors for cutout failure in geriatric intertrochanteric fracture patients after cephalomedullary nail fixation. METHODS: A retrospective review of 518 elderly patients who underwent cephalomedullary nail fixation for intertrochanteric fractures between January 2008 and August 2018 was conducted, including 167 males and 351 females, age from 65 to 97 years old. All patients were followed up for at least one year after surgery and divided into a healed group and a cutout group based on whether the hip screw cutout occurred. Among all patients, 10 cases experienced hip screw cutout. The general information, surgical data, and radiological data of the two groups were compared, and risk factors influencing hip screw cutout were analyzed. Propensity score matching was then performed on the cutout group based on gender, age, body mass index(BMI), and American Society of Anesthesiologists(ASA), and 40 patients from the healed group were matched at a ratio of 1∶4. Key risk factors affecting hip screw cutout were further analyzed. Multivariable logistic regression analysis was conducted to evaluate associations between variables and cutout failure. RESULTS: There were no statistically significant differences between the healed group and the cutout group in terms of age, gender, BMI, ASA, and AO classification. However, statistically significant differences were observed between the two groups in terms of reduction quality(P=0.003) and tip-apex distance(TAD), P<0.001. Multivariate analysis identified poor reduction quality OR=23.138, 95%CI(2.163, 247.551), P=0.009 and TAD≥25 mm OR=30.538, 95%CI(2.935, 317.770), P=0.004 as independent risk factors for cutout failure. CONCLUSION The present study identified poor reduction quality and TAD≥25 mm as factors for cutout failure in geriatric intertrochanteric fractures treated with cephalomedullary nails. Further studies are needed to calculate the optimal TAD for cephalomedullary nails.

Objective:To evaluate the clinical efficacy of botulinum toxin type A (BTX-A) injection in enhancing chin aesthetics.Methods:A retrospective analysis was conducted on patients with suboptimal chin aesthetics who underwent dual-plane BTX-A injection at Plastic Surgery Hospital, Chinese Academy of Medical Sciences between August 2023 and March 2024. Prior to injection, patients were instructed to repeatedly pucker their lips forward and upward to identify the most prominent points of the mentalis muscle for injection. A 13 mm 30 G needle was inserted perpendicularly into the muscle layer, and BTX-A was administered at a concentration of 20 U/ml, with 3 U per injection point. For the patients exhibiting significant orange peel signs at rest, intradermal deep-layer BTX-A injection was concurrently performed at a concentration of 5 U/ml, with 0.5 U per linear track. Postoperative follow-up was conducted, and third-party physicians assessed pre- and post-treatment photographs using the global aesthetic improvement scale (GAIS) (scores ranging from 5 to 1, representing worse, no improvement, mild improvement, moderate improvement, and significant improvement, respectively). Patient satisfaction was also surveyed [categorized as very satisfied, satisfied, dissatisfied, or very dissatisfied; satisfaction rate = (very satisfied + satisfied) cases/total cases × 100%], along with their willingness to undergo repeated injections and recommend the procedure to others. Descriptive statistical analysis was performed using SPSS 24.0 software. Normally distributed continuous data were expressed as Mean±SD, and categorical data were expressed as counts (%).Results:A total of 120 patients were included, comprising 11 males and 109 females, aged 22-39 years (mean age of 33.3 years). Follow-up ranged from 1 to 5 months (mean of 1.3 months). Postoperatively, 102 patients reported subjective improvement in chin appearance, characterized by enhanced fullness and roundness of the chin. Thirty-one patients noted a slight elevation of the submental fat pad and improved definition of the cervicomental angle. The mean GAIS score was 1.61±0.78, with 76 cases scoring 1, 24 cases scoring 2, 10 cases scoring 3, and 10 cases scoring 4. Improvement (scores 1-3) was achieved in 91.7% (110/120) of patients. The subjective satisfaction rate was 85.0% (102/120), and 94 patients (78.3%) expressed willingness to undergo repeated injections and recommend the procedure to family or friends. Early postoperative complications included localized bruising in 17 cases, which was resolved within 10 d, and transient fine motor dysfunction of the lower jaw in 23 cases, with normal chewing, swallowing, and facial expressions, all of which were resolved completely within 6 weeks. No cases of mouth deviation, facial paralysis, allergic reactions, or other complications were observed.Conclusion:The application of BTX-A via intramuscular mentalis injection combined with intradermal deep-layer injection significantly improves both dynamic and static chin aesthetics. However, some common complications also ask for the further attention of practitioners.

Objective:To evaluate the efficacy of transumbilical single-port robotic-assisted laparoscopic surgery for congenital choledochal cysts in children.Methods:Clinical data of 13 children with congenital choledochal cysts undergoing surgery at the Provincial Hospital of Fuzhou University from January 2024 to June 2024 were retrospectively analyzed, including 4 males and 9 females, aged 48 (24, 60) months. All children underwent transumbilical single-port robotic-assisted laparoscopic radical resection of congenital choledochal cyst with common hepatic duct jejunum Roun-en-Y anastomosis by the same surgeon. The efficacy of this technique was evaluated by surgical safety indicators such as operation time and intra-operative blood loss, as well as indicators of the postoperative scar assessment scale (OSAS).Results:All surgeries were successfully performed without conversion to open surgery. The operation time was (200±22) min. The blood loss was (8.07±2.56) ml without intraoperative blood transfusion. The time to start water feeding was (2.76±0.83) d and the time to start liquid diet was (3.92±1.12) d. The postoperative hospital stay was (7.00±3.37) d and the postoperative follow-up time was (5.38±2.06) months. No postoperative complications such as bile reflux gastritis and cholangitis were seen in patients. No dilatation of the common hepatic duct or intrahepatic bile ducts were observed at three months postoperatively. There were good indicators of satisfaction with the appearance of wounds as assessed by OSAS.Conclusion:Transumbilical single-port robotic-assisted laparoscopic surgery could be safe and effective for congenital choledochal cysts in children.
