Objective To analyze the anesthetic effect and hemodynamic impact of oxybutynin(OBI)combined with dexmedetomidine(DEX)on patients undergoing endoscopic dacryocystorhinostomy(En-DCR).Methods Patients who underwent En-DCR from February 2024 to May 2024 at Mianyang Wanjiang Eye Hospital were recruited.They were randomly divided into the DEX group(DEX administration only)and the combined group(DEX combined with OLI administration)according to the random number table method.The primary observational index in this study was the 24-h postoperative pain numerical rating scale(NRS)scores.The secondary observation indexes were heart rate(HR),mean arterial pressure(MAP),respiratory recovery time(SRT),extubation time(ET)and awakening time(AT),peak systolic value(PSV),end-diastolic blood flow velocity(EDV),resistance index(RI)and blood flow(BF).The occurrence of adverse events in patients during hospitalization was observed and recorded.Results A total of 80 patients were included in the study,with 40 in each of the DEX group and the combined group.In terms of analgesia,the NRS scores in the combined group were lower than those in the DEX group at T1(within 0.5 h after catheter removal),T2(4 h postoperatively),T3(8 h postoperatively),and T4(24 h postoperatively)(P＜0.05),and the remedial analgesia rate in the combined group was significantly lower than that in the DEX group(P＜0.05).Regarding anesthetic effects,HR and MAP at time points T6(during induction of anesthesia),T7(intraoperatively)and T8(during resuscitation)were lower in the combined group than in the DEX group(P＜0.05);and SRT,ET and AT were shorter in the combined group compared with the DEX group(P＜0.05).In terms of hemodynamics,at 24 h postoperatively,PSV,EDV and BF were significantly higher in both groups compared with those before anesthesia,whereas RI was significantly lower than before anesthesia(P＜0.05);PSV,EDV and BF were higher in the combined group than those in the DEX group,and RI was lower than that in the DEX group(P＜0.05).Regarding adverse reactions,the incidence of adverse reactions in the combined group was significantly lower than that in the DEX group(P＜0.05).Conclusion OLI combined with DEX prophylactic analgesia for patients with En-DCR is effective,not only to reduce postoperative pain,stabilize hemodynamics,shorten the time of extubation and awakening,and reduce the incidence of adverse reactions.

Objective:To analyze the incidence and clinical phenotype of the concomitant extragenital malformations in the patients with female reproductive tract anomalies.Methods:A retrospective study was conducted using clinical data of hospitalized patients diagnosed with uterine, cervical, or vaginal malformations from January 2003 to December 2022 in Peking Union Medical College Hospital. The malformations were classified according to American Society for Reproductive Medicine müllerian anomalies classification 2021, and in each type, the incidence and specific manifestations of concomitant extragnital malformations were analyzed.Results:A total of 444 patients were included. The overall incidence of concomitant extragenital malformations was 43.5% (193/444), including urinary system, skeletal system, and other system malformations. Renal malformations on the obstructed side were present in all patients with oblique vaginal septum syndrome (100.0%, 78/78). The total incidence of concomitant extragnital malformations was as high as 8/11 in uterus didelphys, 43.5% (10/23) in unicornuate uterus, 33.6% (79/235) in Mayer-Rokitansky-Küster-Hauser syndrome, 18.8% (6/32) in septate uterus and 18.5% (12/65) in cervical agenesis. Urinary system malformations (30.6%, 136/444) and skeletal system malformations (13.5%, 60/444) were the most common concomitant malformations in all types, in which, unilateral renal agenesis and scoliosis were the most common.Conclusions:Urinary and skeletal system malformations are important features of female reproductive tract anomalies. Urologic ultrasonography and spinal roentgenogram are recommended for all patients with female reproductive tract anomalies.

Objective:To establish an automated labeling method of 18F-AlF-1, 4, 7-triazocyclohexane-1, 4, 7-triacetic acid- D-Phe1-Tyr3-Thr8-octreotide (NOTATATE) and perform neuroendocrine tumor (NET) imaging. Methods:Based on the GE-FASTLab2 synthesis module, 18F-AlF-NOTATATE was automatically prepared by one-step chelation labeling with aluminum fluoride, and its labeling conditions were optimized. The product quality was analyzed. One patient (male, 47 years old) with lower rectal segment NET and one patient (female, 52 years old) with pancreatic NET underwent 18F-AlF-NOTATATE PET/CT imaging. Results:18F-AlF-NOTATATE was successfully prepared with a total synthesis time of 35 min. The optimized radiochemical yield was (23.8±3.1)% (without decay correction, n=3), the radioactivity was (4.63±0.68) GBq, and the radiochemical purity was >95%. The stability was good, and the product quality met the requirements. 18F-AlF-NOTATATE showed clear imaging in the patient with rectal segment NET, with SUV max of 13.3 and tumor/liver ratio of 3.3. Metastatic lesions in the liver, lymph nodes, and ribs showed high SUV max and tumor/liver ratios. The imaging of the pancreatic NET patient showed an abnormal increase in local radioactive uptake at the uncinate process of the pancreatic head, with SUV max of 5.6 and SUV max of 6.3 and the tumor/liver ratio of 2.3 after 2-hours imaging. Conclusions:Using the GE-FASTLab2 synthesis module, 18F-AlF-NOTATATE can be prepared with high activity. The preparation is simple, the method is stable, and the product has high radiochemical purity. 18F-AlF-NOTATATE exhibits good imaging performance in NET patients, providing valuable information for diagnosis, treatment, and prognosis evaluation.

Objective:To investigate the impact of " staging" hybrid coronary artery revascularization (HCR) on the short-and long-term efficacy of patients with multiple coronary artery lesions.Methods:A retrospective case-control study was conducted. Eighty patients with multiple coronary artery lesions admitted to the Baoding Second Central Hospital from January 2017 to October 2018 were selected and divided into two groups according to different surgical methods. Forty patients were treated with " staging" HCR and were designated as the HCR group, and 40 patients were treated with off-pump coronary artery bypass grafting (OPCAB) and were designated as the OPCAB group. The perioperative related indicators and perioperative serious complications were compared between the two groups. The serum myocardial injury marker levels were detected preoperatively and 48 hours postoperatively, including heart-type fatty acid binding protein (H-FABP) and troponin I (cTnI). All subjects were followed up for at least 3 years to calculate the incidence of major adverse cardiovascular and cerebrovascular events (MACCE).Results:The bypass surgery time, mechanical ventilation time, ICU stay time, and total hospital stay time in the HCR group were all less than those in the OPCAB group (all P<0.05), and the incision length in the HCR group was shorter than that in the OPCAB group ( P<0.05). The intraoperative bleeding volume, postoperative 24-hour drainage volume, red blood cell transfusion volume, and plasma transfusion volume in the HCR group were all less than those in the OPCAB group (all P<0.05). Forty-eight hours after surgery, the serum H-FABP and cTnI levels in both groups were significantly higher than those preoperatively (all P<0.05), but the increase was more significant in the OPCAB group (all P<0.05). The perioperative serious complication rate in the HCR group was 2.50%(1/40), which was significantly lower than that in the OPCAB group [20.00%(8/40)] ( P<0.05). During the 3-year follow-up after surgery, the MACCE incidence in the HCR group was 12.50%(5/40), and that in the OPCAB group was 22.50%(9/40). There was no significant difference in the long-term MACCE incidence between the two groups ( P>0.05). Conclusions:" Staging" HCR treatment for multiple coronary artery lesions can achieve ideal surgical results. Compared with OPCAB, its short-term efficacy is more significant, and long-term efficacy is equivalent.

OBJECTIVE: To analyze the intellectual landscape and emerging research trends of Chinese medicine (CM) in the management of pediatric asthma through a scientometric study. METHODS: Publications related to CM in the management of pediatric asthma were retrieved from the Web of Science Core Collection using relevant keywords. A scientometric study was performed using CiteSpace and VOSviewer. RESULTS: A total of 1,673 original articles and reviews from 1991 to 2019 were included in the analysis. The amount of annual publications had a gradual increase with time. USA was the major contributor both in country and institution analyses. Based on the co-citation, the published journals were grouped into 4 clusters. Keyword analysis indicated that the main hotspots were: (1) comprehensive management; (2) risk factors, mechanism, and prevalence; (3) prevention and treatment; (4) inflammation; and (5) environmental research. Lastly, we predicted that three emerging trends were quality of life promotion, immune response, and combination therapy. CONCLUSIONS CM research in the management of pediatric asthma will maintain the current trend of steady growth. This scientometric analysis may help scientists to identify the areas of interests and future directions in the field.

Objective:To explore the clinical efficacy and safety of different surgical procedures of Mayo level Ⅳ inferior vena cava tumor thrombus(IVC-TT).Methods:The clinical and pathological data of 36 patients with Mayo level Ⅳ tumor thrombus were collected in three large clinical centers in China, including 18 cases in PLA General Hospital, 7 cases in Nanfang Hospital, and 11 cases in Renji Hospital. There were 25 males and 11 females.The median age was 56.5 years (53-67 years old). The average body mass index was 24.18±2.55 kg/m 2. The average diameter of renal tumors was 8.24±3.25 cm. The average length of inferior vena cava tumor thrombus was 12.89±2.50 cm. Mayo level Ⅳ tumor thrombus were divided into level Ⅳa and level Ⅳb (301 classification) based on the criterion of whether the proximal end of the thrombus has invaded the right atrium. Among them, level Ⅳa patients underwent robot-assisted inferior vena cava thrombectomy without cardiopulmonary bypass(CPB-free group, 6 cases). Level Ⅳb patients underwent robot-assisted inferior vena cava thrombectomy with cardiopulmonary bypass(CPB group, 12 cases) or cardiopulmonary bypass with deep hypothermic circulatory arrest assisted inferior vena cava thrombectomy(CPB/DHCA group, 18 cases). The baseline data of the three groups of patients were comparable. The perioperative results and long-term survival data after surgery were compared with different surgical methods for grade Ⅳcancer thrombosis. Results:All operations were successfully completed. Compared with the CPB group, the CPB-free group had a shorter first portal blocking time[17.5(15-36)min vs. 36.5(12-102)min, P=0.044], less intraoperative bleeding [2 350(1 000-3 000)ml vs. 3 500 (1 500-12 000)ml, P=0.043] and a lower allogeneic blood transfusion [1 250(500-2 000)ml vs. 2 185(700-5 800)ml, P=0.049]. Compared with the CPB/DHCA group, the CPB-free group had an advantage in reducing intraoperative allogeneic blood transfusion [1 250(500-2 000)ml vs. 2 700(1 200-10 000)ml, P=0.003]. There were no significant differences between groups in terms of duration of surgery and postoperative hospital stay. Among the 36 patients in this group, 23(64%) developed major complications (level Ⅲ or above), including 9 (25%) grade Ⅲ, 12 (33%) grade Ⅳ, and 2 (6%) grade Ⅴ. The CPB-free group had a relatively low complication rate of grade Ⅳ or above [ 17% (1/6) vs.42% (5/12) vs.44% (8/18)]. There were no statistical differences in median progression-free survival (16.4 vs.12.3 vs.18.0 months, P=0.695) and overall survival (30.1 vs.30.2 vs.37.7 months, P=0.674) between the groups. Conclusions:Robot-assisted inferior vena cava thrombectomy without cardiopulmonary bypass has the advantages of short ischemia time of organs, less intraoperative bleeding, and low incidence of major complications, which can be used as a safe and feasible surgical strategy for selected level Ⅳ tumor thrombus.

Objective:To analyze the effects of seasonal autoregressive integrated moving average model (SARIMA), generalized additive model (GAM), and long-short term memory model (LSTM) in fitting and predicting the incidence of hemorrhagic fever with renal syndrome (HFRS), so as to provide references for optimizing the HFRS prediction model.Methods:The monthly incidence data of HFRS from 2004 to 2017 of the whole country and the top 9 provinces with the highest incidence of HFRS (Heilongjiang, Shaanxi, Jilin, Liaoning, Shandong, Hebei, Jiangxi, Zhejiang and Hunan) were collected in the Public Health Science Data Center (https://www.phsciencedata.cn/), of which the data from 2004 to 2016 were used as training data, and the data from January to December 2017 were used as test data. The SARIMA, GAM, and LSTM of HFRS incidence in the whole country and 9 provinces were fitted with the training data; the fitted model was used to predict the incidence of HFRS from January to December 2017, and compared with the test data. The mean absolute percentage error ( MAPE) was used to evaluate the model fitting and prediction accuracy. When MAPE < 20%, the model fitting or prediction effect was good, 20%-50% was acceptable, and > 50% was poor. Results:From the perspective of overall fitting and prediction effect, the optimal model for the whole country and Heilongjiang, Shaanxi, Jilin, Liaoning and Jiangxi was SARIMA ( MAPE was 19.68%, 20.48%, 44.25%, 19.59%, 23.82% and 35.29%, respectively), among which the fitting and prediction effects of the whole country and Jilin were good, and the rest were acceptable. The optimal model for Shandong and Zhejiang was GAM ( MAPE was 18.29% and 21.25%, respectively), the fitting and prediction effect of Shandong was good, and Zhejiang was acceptable. The optimal model for Hebei and Hunan was LSTM ( MAPE was 26.52% and 22.69%, respectively), and the fitting and prediction effects were acceptable. From the perspective of fitting effect, GAM had the highest fitting accuracy in the whole country data, with MAPE = 10.44%. From the perspective of prediction effect, LSTM had the highest prediction accuracy in the whole country data, with MAPE = 12.23%. Conclusions:SARIMA, GAM, and LSTM can all be used as the optimal models for fitting the incidence of HFRS, but the optimal models fitted in different regions show great differences. In the future, in the establishment of HFRS prediction models, as many alternative models as possible should be included for screening to ensure higher fitting and prediction accuracy.

Objective:To evaluate the efficacy of holographic image technology in robot-assisted laparoscopic radical prostatectomy (RARP).Methods:The clinical data of 34 patients with prostate cancer who underwent RARP in our hospital during October 2020 and December 2020 was analyzed retrospectively. The average age of the patients was 67.8 (52-78) years. The mean BMI was 25.8 (18.0-32.3) kg/m 2. The median level of PSA before surgery was 13.4 (2-149) ng/ml. Median prostate volume was 31.7 (9.5-159.1) ml. EAU risk groups for biochemical recurrence of localised and locally advanced prostate cancer were list as below: 5 cases of low-risk, 7 cases of medium-risk, 22 cases of high-risk. There were 9, 16, 9 cases with the ASA score of 1, 2, 3 point, respectively. Preoperative Gleason score of 34 patients were list as below: 9 cases in score ≤6 group, 15 cases in score=7 group, 10 cases in score ≥8 group. For clinical stage before the surgery, 13 cases ≤T 2a stage, 1 case in T 2b stage, 20 cases ≥T 2c stage. The engineers established holographic images of 34 patients based on multiparametric magnetic resonance imaging (mpMRI) and the reports before the operation. Surgeons can obtain the size and location of tumors, surrounding neurovascular bundles visually by revolving, assembling, disassembling and concealing images, which was helpful for pre-surgery planning. By manipulating the holographic images extracorporeally, surgeons can discriminate Internal sphincter of urinary bladder and vesicoprostatic muscle, neurovascular bundles, membranous part, seminal vesicle easily, which improves the operation accuracy. Results:All 34 cases underwent operation successfully without transferring to open surgery. The median operative time was 157.5 (95-276) min with an estimated blood loss of 50 (20-300) ml. The median drainage removal time was 2 d and median hospitalization time was 3.5 d, respectively. The catheters were removed within an average time of 20.5 d. For postoperative Gleason score, there were 2 cases in score ≤6 group, 16 cases in score =7 group, 8 cases in score ≥8 group and 8 cases can’t make a score. For clinical stage after the surgery, 10 cases were ≤T 2a stage, 1 case was T 2b stage, 23 cases were ≥cT 2c stage. 22 cases underwent pelvic lymph node dissection, including a patient with right iliac fossa lymph node metastasis. There were 2 cases with positive surgical margin and 3 cases with Clavien-DindoⅠcomplications. The rate of 1-month and 3-month urinary continence were 47.1% and79.4%, respectively, 8 cases recovered erectile function after 3 month. Conclusions:Holographic image technology can promote cancer dissection completely, achieve urinary continence early and reduce perioperative complications tremendously. The technology is the "intraoperative security" for the accurate surgical treatment of prostate cancer.

OBJECTIVE: To explore the molecular basis for a pedigree affected with Darier-White disease. METHODS: Genomic DNA was isolated from 3 patients and 1 unaffected member from the pedigree, as well as 80 healthy controls. Targeted sequence capture and next-generation sequencing were used to screen mutations of skin disease-related genes. Candidate mutations were verified by Sanger sequencing, and co-segregation analysis was carried out to confirm the pathogenicity of mutation. Conservation analysis and protein structure and function were also predicted with Bioinformatic tools. RESULTS: A heterozygous mutation c.2246G>T (p.G749V) was identified in exon 15 of ATP2A2 gene in all 3 patients from the pedigree, but not in the unaffected member or 80 healthy controls. The corresponding amino acid was highly conserved, and mutation of which can lead to structural and functional changes of the protein. CONCLUSION The c.2246G>T missense mutation of the ATP2A2 gene probably underlies the Darier-White disease in this pedigree by causing damages to the structure and function of sarcoplasmic/endoplasmic reticulum calcium ATPase 2 (SERCA2).
