The recombinant human thyroid-stimulating hormone (rhTSH) can be used for differentiated thyroid cancer (DTC) preparation before ¹³¹I therapy, and follow-up. Since its approval by the American Food and Drug Administration (FDA) in 1998, rhTSH has been clinically used in European countries, the United States, and other countries for nearly 30 years. In April 2024, China’s first independently developed rhTSH agent was approved. Based on clinical experience and evidence from domestic and international studies, an expert consensus on the application of rhTSH has been developed following thorough consultations among experts. The consensus offers evidence-based recommendations to guide the appropriate use of rhTSH in clinical practice.

Objective:To explore the relationship between the stability of the pulse perfusion index(PI)value and Pulse oximetry(SpO2)alarms in monitor for neonates,so as to reduce the false alarm rate.Methods:A monitor with dual blood oxygen module(Module 1 and Module 2)was used to simultaneously monitor different parts of neonates.If both modules alarmed simultaneously,it was considered as a valid alarm.If only one module alarmed while the others was normal,it was considered as an invalid alarm.The PI values were classified into A,B and C categories based on the calculated variance of PI values.The distribution of valid alarms in the three categories was analyzed by using statistical method.The eighteen neonates who admitted to the neonatal department of Shanxi Children's Hospital from May11,2023 to May 19,2023 were monitored,with an average monitoring time of 7.3 hours for each case.The false alarm rates of the monitor with dual blood oxygen module were compared among categories A,B and C,as well as the correlations between different PI values and SpO2 alarms.Results:The times of monitored valid alarm of two non-invasive blood oxygen modules(Module 1 and Module 2)were 41 times,and the false alarm rates of categories A and C were significantly higher than that of category B.The times of categories A,B and C of the monitored PI values of Module 1 and Module 2 were respectively(6,34,1)and(8,30,3),which appeared weak correlation with the times of valid alarm of SpO2(r=0.230,0.259,P<0.05).The result of univariate binary logistic regression indicated PI value could not predict SpO2 alarms in SpO2 alarm.Conclusion:PI value can reflect the affected accuracy of SpO2 alarm when the data that are collected by prober are instability.The PI value that is collected by single SpO2 prober can indirectly reflect that the instable data of collection can affect the correctness of SpO2 alarm,while the simultaneous monitor of adopting monitor with dual oxygen module can improve the accuracy of SpO2 alarms in monitoring for neonates.

Objective:To establish ultra-performance liquid chromatography (UPLC) fingerprint chromatograms for Erigeron breviscapu from different origins and storage conditions; To identify the Erigeron breviscapus from different habitats by chemometric analysis.Methods:Acquity UPLC HSS T3 (2.1 mm×100 mm,1.8 μm) chromatography column was used; mobile phase was 0.1% formic acid aqueous solution-acetonitrile; detection wavelength was 268 nm; flow rate was 0.25 ml/min; column temperature was 35 ℃; injection volume was 2 μl gradient elution. The UPLC fingerprint of Erigeron breviscapu from different origins was established. Similarity evaluation combined with chemometric analysis methods such as clustering analysis (CA), principal component analysis (PCA), orthogonal partial least squares method - discriminant analysis (OPLS-DA) were used to identify the origin of Breviscapine from different places. Fingerprint technology was used to evaluate the similarity of storage conditions for Erigeron breviscapu.Results:The UPLC fingerprint method met the methodological requirements. 30 batches of Erigeron breviscapus had 24 common peaks, and the similarity between Xingyi in Guizhou and Huize in Qujing was 0.702-0.783, while the similarity between Honghe Luli, Kunming Fuming and Dali was 0.861-0.970. All samples were divided into two categories according to their origin by CA: category Ⅰ: Xingyi in Guizhou and Huize in Qujing, and category Ⅱ: Dali, Kunming Fuming and Honghe Luli. The results of PCA were consistent with CA. OPLS-DA screened out 10 differential markers of Erigeron breviscapus from different habitats. Moreover, a total of 40 common peaks were identified in six batches of Erigeron breviscapus samples stored under different conditions. Based on the similarity analysis, Erigeron breviscapus samples stored at 30% humidity and 70% humidity were classified into two separate categories.Conclusions:The fingerprint method constructed in this study is stable and reliable, and the predictive ability and reliability of the OPLS-DA model are excellent. By combining the two methods, a clear division can be made between Erigeron breviscapus from Yunnan and Guizhou. Humidity conditions are an important factor in storing Erigeron breviscapus.

Objective:To investigate the safety and feasibility of the domestic single-port serpentine-arm robotic surgical system for pyeloplasty in children with congenital ureteropelvic junction obstruction(UPJO).Methods:Data of UPJO patients who underwent pyeloplasty using a domestic single-port ser-pentine-arm robotic surgical system(Beijing Surgerii Robotics Co.,Ltd.)in Beijing Children's Hospital from November 2023 to February 2024 were retrospectively collected.The patients who were not receiving surgical treatment for the first time,had hydronephrosis caused by other reasons(such as ureterovesical junction obstruction,posterior urethral valve,urinary tract stones,vesicoureteral reflux,ureterocele,etc.),had other urinary tract malformations(such as duplicated kidneys,congenital renal dysplasia,etc.),had severe atrophy of the affected kidney,severe urinary tract infection or severe renal insufficien-cy were excluded.All the surgeries were performed through the umbilicus and abdominal cavity,and the operation time,number of intraoperative incisions,incision size,intraoperative blood loss,and peri-operative complications were recorded.Statistical analysis was performed to compare changes in the an-teroposterior pelvic diameter(APD)and renal cortical thickness before surgery and 6 months postopera-tively.Results:A total of 10 patients were included(8 males and 2 females),with an average age of(10.20±3.12)years.Nine patients were on the left side and one patient was on the right side.The average height was(142.0±17.8)cm and the average weight was(37.6±17.9)kg.All the patients underwent surgery using the domestic single-port robotic surgery system,and no patient was converted to open pyeloplasty.The total operation time was(237±96)min,and the operation time on the operating table was(162.0±69.3)min.The intraoperative blood loss was 5.00(2.25,5.00)mL.No compli-cations,such as bleeding,urine extravasation,fever,and poor wound healing occurred during the perioperative period.Compared with the preoperative measurements,the APD was significantly shortened postoperatively(P=0.005),and the renal cortical thickness significantly increased(P=0.011).Con-clusion:The domestic single-port serpentine arm robotic surgical system is safe and feasible for UPJO pyeloplasty in children,with good surgical results,and can be promoted and applied in most domestic medical centers.

Objective To Investigate the efficacy of modified electroconvulsive therapy(MECT)in patients with schizophrenia across different genders.Methods From May 2018 to August 2022,481 patients with schizophrenia were recruited from three psychiatric hospitals in Luzhou,Zigong,and Yibin.According to gender grouping,both groups received adjunctive MECT treatment for two consecutive weeks for a total of six treatments.The differences in positive and negative syndrome scale(PANSS)scores before and after treatment,UKU adverse reaction rating scale(UKU),and gastrointestinal symptom rating scale(GSRS)scores were compared between the two groups.Results After quality control,463 cases were followed up for analysis including 246 males and 217 females.Compared with pre-treatment,the total PANSS score and scores on each subscale were significantly reduced in both genders after treatment(P<0.001).When comparing the reduction rates between the groups,the male patients showed a higher reduction rate in negative symptoms than the female patients(31.24%±30.24%vs.25.80%±33.96%,P<0.05).However,there were no significant differences between the two groups in the reduction rates of the total score,positive symptoms,and general psychopathology(P>0.05).The comparison of adverse reactions showed that the frequency of other types of adverse reactions was higher in female patients than in male patients(47.47%vs.37.80%,P<0.05).However,no significant differences were observed in the adverse reactions related to the mental,neurological,autonomic nervous system,and gastrointestinal systems(P>0.05).Correlation analysis revealed that the reduction rate of the PANSS total score was positively correlated with smoking history(r=0.135,P=0.034)and alcohol history(r=0.160,P=0.012)in male patients,while the reduction rate of the PANSS total score was negatively correlated with the disease duration(r=-0.210,P=0.002)and positively correlated with the age of onset(r=0.145,P=0.032)in female patients.Conclusion MECT is significantly effective for both male and female patients with schizophrenia.Compared to female patients,MECT shows a more pronounced effect on negative symptoms in male patients.Additionally,the factors related to the efficacy of MECT differ between genders,indicating that it is necessary to consider the clinical characteristics of patients comprehensively when selecting an MECT treatment plan.

Pediatric urological non-Hodgkin lymphoma is relatively rare.When a single renal or ureteral tumor with multiple lymph node or bone metastases is present, it is very easy to be misdiagnosed as urinary tumor with metastasis, resulting in unnecessary radical nephrectomy. This paper reports two cases of non-Hodgkin lymphoma presenting with single urinary nodules. Case 1 was diagnosed with a 4.5cm tumor in the right kidney due to fever and fatigue. CT and PET-CT showed multiple bone destruction and lymph node metastasis. Renal biopsy was performed and ALK-positive anaplastic large cell lymphoma was diagnosed. Chemotherapy was effective for 6 months. Case 2 was diagnosed with left hydronephrosis due to intermittent low back pain for 2 weeks. Ultrasound examination revealed ureteral dilation with left hydronephrosis and low echo occupying of the lower ureter. The patient had sudden blurred vision before surgery. MRI examination revealed space occupying in the right optic nerve frame, and PET-CT found multiple bone, lymph nodes and nerve invasion. A lymph node biopsy was performed and Burkitt lymphoma was diagnosed. After 6 months of chemotherapy and radiotherapy, the tumor shrank significantly.
