OBJECTIVE To explore the influencing factors for immune-related endocrine toxicity in the treatment of malignant solid tumors with sintilimab， aiming to provide a reference for rational drug use. METHODS Case data were collected from patients with malignant solid tumors， who were treated with sintilimab at the First Affiliated Hospital of Jinzhou Medical University from January 1， 2020 to December 31， 2024， using the electronic medical record system. The patients were divided into an endocrine immune-related adverse events （irAEs） group and a non-endocrine irAEs group based on whether they developed immune-related endocrine toxicity after sintilimab administration. The statistical significance of predictive variables was examined through univariate and multivariate Logistic regression methods. RESULTS A total of 224 patients were enrolled， including 138 cases （61.6%） in the non-endocrine irAEs group and 86 cases （38.4%） in the endocrine irAEs group. After univariate and multivariate Logistic regression analysis， a treatment period of 1-12 cycles was identified as an independent influencing factor for immune-related endocrine toxicity [OR＝7.175， 95%CI （1.239， 41.563）， P ＜0.05 ] ， immune-related hyperglycemia [OR＝6.600， 95%CI （1.053， 41.359）， P ＜0.05 ] ， and immune-related subclinical hypothyroidism [OR＝20.200， 95%CI （3.224， 126.558）， P ＜0.05 ] . The combination with paclitaxel-based drugs was identified as an independent influencing factor for immune-related subclinical hyperthyroidism [OR＝6.410， 95%CI （1.790， 22.955）， P ＜0.05 ] . CONCLUSIONS Among patients treated with sintilimab， the treatment cycle is a risk factor for immune-related endocrine toxicity， immune-related hyperglycemia and immune-related subclinical hypothyroidism. The combination of paclitaxel-based drugs is a risk factor for immune-related subclinical hyperthyroidism. It is recommended that when applying sintilimab in clinical practice， especially during the first few treatment cycles， the relevant endocrine indicators should be dynamically monitored in a standardized manner. In addition， special attention should be paid to patients treated with the combination of paclitaxel-based drugs to be vigilant against the occurrence of endocrine adverse events.

Objective To explore the principle of antibacterial drug therapy and the strategy of program optimization in elderly patients with Helicobacter pylori（Hp）. Methods The common therapeutic regimen of Hp was summarized, and the better therapeutic regimen of elderly Hp patients was screened ultimately. Results Amoxicillin and cefuroxime were relatively safe compared with other recommended antibacterial drugs. Using other commonly antibiotics for Hp should pay attention to the disease of patients and current drug. Conclusion Elderly patients usually suffered from a variety of diseases and required multiple drugs. The application of therapeutic regimen for elderly patients with Hp should be supposed to fully weigh the risks and benefits.

OBJECTIVES: To evaluate preterm white matter injury (PWMI) in neonatal rats using multimodal magnetic resonance imaging (MRI) combined with histological assessments and to explore its underlying mechanisms. METHODS: Healthy 3-day-old Sprague-Dawley neonatal rats were randomly divided into a sham operation group and a PWMI group (n=12 in each group). A PWMI model was established in neonatal rats through hypoxia-ischemia. Laser speckle imaging was used to observe changes in cerebral oxygen saturation and blood flow at different time points post-modeling. Multimodal MRI was employed to assess the condition of white matter injury, while hematoxylin-eosin staining was utilized to observe morphological changes in the striatal area on the injured side. Immunofluorescence staining was performed to detect the proliferation and differentiation of oligodendrocyte precursor cells. RESULTS: At 0, 6, 12, 24, and 72 hours post-modeling, the relative blood flow and relative oxygen saturation on the injured side in the PWMI group were significantly lower than those in the sham operation group (P<0.05). At 24 hours post-modeling, T2-weighted imaging showed high signals in the white matter of the injured side in the PWMI group, with relative apparent diffusion coefficient values and Lorenz differential values being lower than those in the sham operation group (P<0.001); additionally, the arrangement of nerve cells in the PWMI group was disordered, and the number of EdU⁺PDGFR-α⁺ cells was higher than that in the sham operation group (P<0.001). At 28 days post-modeling, the relative fractional anisotropy values, the number of EdU⁺Olig2⁺ cells, and the fluorescence intensity of myelin basic protein and neurofilament protein 200 in the white matter region of the PWMI group were all lower than those in the sham operation group (P<0.001). CONCLUSIONS Multimodal MRI can evaluate early and long-term changes in PWMI in neonatal rat models in vivo, providing both imaging and pathological evidence for the diagnosis and treatment of PWMI in neonates. Hypoxia-ischemia inhibits the proliferation and differentiation of oligodendrocyte precursor cells in neonatal rats, leading to PWMI.

AIM To investigate the variations in mercury dissolution from HgS-containing traditional medicines in three kinds of simulated gastrointestinal dissolution media.METHODS 39 batches of 15 types of HgS-containing traditional medicines were collected,total mercury content and dissolved mercury concentrations in simulated gastric fluid,simulated intestinal fluid,and L-cysteine-containing simulated intestinal fluid were measured.The maximum daily intake of total mercury and soluble mercury was calculated based on the maximum daily clinical dosage.RESULTS Among the 15 types of medicines,the maximum daily intake of total mercury varied by 156 times,the daily intake of soluble mercury varied by 3 502 times in simulated gastric fluid,313 times in simulated intestinal fluid,and 10 663 times in L-cysteine-containing simulated intestinal fluid,approximately.CONCLUSION For the 15 types of HgS-containing traditional medicines,the daily maximum intake of soluble mercury showed greater variations than that of total mercury.Soluble mercury concentration is more closely correlated with intestinal absorption of mercury and thus represents a more rational quality control indicator for HgS-containing traditional medicines.

Objective To understand the molecular epidemiological characteristics and hypervirulence evolution trend of ST11 carbapenem-resistant Klebsiella pneumoniae(CRKP)isolated from medical institutions in Shanghai,and provide scientific basis for formulating the prevention and control measures of drug-resistant organisms.Methods A total of 201 strains of CRKP isolated from 12 medical institutions in Shanghai from 2021 to 2022 were collected.Antimicrobial susceptibility testing and whole genome sequencing were performed.The concatenated data was used for multilocus sequencing typing(MLST),serum typing(wzi typing),as well as analysis of resistance and viru-lence genes.Results All 201 CRKP strains were multidrug-resistant organisms(MDROs).These strains were al-most completely resistant to carbapenems,cephalosporins,and quinolones.Drug resistance gene analysis showed that 93.03％of CRKP strains carried KPC gene.201 CRKP strains were divided into 6 ST types and 10 capsule wzi types,with ST11-KL64(n=104)being the dominant type,followed by ST15-KL19(n=54).52.24％(n=105)of CRKP carried rpmA/rpmA2+iucA+iutA+iroN genes.Conclusion CRKP isolated from medical institutions in Shanghai is mainly ST11-KL64 type with severe multidrug resistance,and more than half of the strains are hyper-virulent carbapenem-resistant Klebsiella pneumoniae(hv-CRKP).It is necessary to continuously strengthen the monitoring of the molecular characteristics of CRKP,so as to prevent outbreaks of healthcare-associated infection.

OBJECTIVE: To evaluate the clinical effect and safety of acupuncture manipulation on treatment of intractable facial paralysis (IFP), and verify the practicality and precision of the Anzhong Facial Paralysis Precision Scale (Eyelid Closure Grading Scale, AFPPS-ECGS). METHODS: A multicentre, single-blind, randomized controlled trial was conducted from October 2022 to June 2024. Eighty-nine IFP participants were randomly assigned to an ordinary acupuncture group (OAG, 45 cases) and a characteristic acupuncture group (CAG, 44 cases) using a random number table method. The main acupoints selected included Yangbai (GB 14), Quanliao (SI 18), Yingxiang (LI 20), Shuigou (GV 26), Dicang (ST 4), Chengjiang (CV 24), Taiyang (EX-HN 5), Jiache (ST 6), Fengchi (GB 20), and Hegu (LI 4). The OAG patients received ordinary acupuncture manipulation, while the CAG received characteristic acupuncture manipulation. Both groups received acupuncture treatment 3 times a week, with 10 times per course, lasting for 10 weeks. Facial recovery was assessed at baseline and after the 1st, 2nd and 3rd treatment course by AFPPS-ECGS and the House-Brackmann (H-B) Grading Scale. Infrared thermography technology was used to observe the temperature difference between healthy and affected sides in various facial regions. Adverse events and laboratory test abnormalities were recorded. The correlation between the scores of the two scales was analyzed using Pearson correlation coefficient. RESULTS: After the 2nd treatment course, the two groups showed statistically significant differences in AFPPS-ECGS scores (P<0.05), with even greater significance after the 3rd course (P<0.01). Similarly, H-B Grading Scale scores demonstrated significant differences between groups following the 3rd treatment course (P<0.05). Regarding temperature measurements, significant differences in temperatures of frontal and ocular areas were observed after the 2nd course (P<0.05), becoming more pronounced after the 3rd course (P<0.01). Additionally, mouth corner temperature differences reached statistical significance by the 3rd course (P<0.05). No safety-related incidents were observed during the study. Correlation analysis revealed that the AFPPS-ECGS and the H-B Grading Scale were strongly correlated (r=0.86, 0.91, 0.93, and 0.91 at baseline, and after 1st, 2nd, and 3rd treatment course, respectively, all P<0.01). CONCLUSIONS Acupuncture is an effective treatment for IFP, and the characteristic acupuncture manipulation enhances the therapeutic effect. The use of the AFPPS-ECGS can more accurately reflect the recovery status of patients with IFP. (Trial registration No. ChiCTR2200065442).

Objective To analyze the risk factors affecting liver regeneration after laparoscopic anatomic liver resection(LALR),and to explore the relationship between postoperative liver regeneration and the prognosis of patients.Methods A retrospective analysis was conducted on the clinical data of 156 patients with liver cancer who underwent LALR treatment at the People's Hospital Affiliated to Shandong First Medical University from January 2021 to December 2023.Three-dimensional liver reconstruction and simulated resection were performed based on CT examination,and the postoperative liver regeneration rate was calculated.The patients were divided into the high regeneration group and the low regeneration group based on the median liver regeneration rate 1 month after surgery,and the univariate and multivariate analyses were performed to analyze the risk factors affecting postoperative liver regeneration.The relationships between post-operative liver regeneration capacity and tumor-free survival rate and overall survival rate of patients were analyzed using the Kaplan-Meier survival curve.Results Significant difference was observed between the future remnant liver volume(FRLV)1 week after operation and the remnant liver volume(RLV)after operation(P<0.05).The liver regeneration rates 1 month and 3 months after operation were significantly higher than that 1 week after operation(P<0.05).The net growth rate of liver volume 1 week after operation was significantly higher than that 1 month and 3 months after operation(P<0.05).The median liver regeneration rate 1 month after operation was 27.81%.Univariate analysis showed that gender,age,drinking history,combined with liver cirrhosis,preoperative predictional RLV,preoperative predictional standard residual liver volume(SRLV),and postoperative platelet count(PLT)were closely related to liver regeneration after operation(P<0.05).Multivariate analysis showed that combined with liver cirrhosis,and high preoperative predictional RLV and SRLV were the independent factors affecting liver regeneration after operation(P<0.05).The postoperative follow-up showed that the cumulative tumor-free survival rate of the high regeneration group was lower than that of the low regeneration group(61.20%vs.75.28%,Log-rank χ2=3.577,P=0.043),and there was no statistically significant difference in the cumulative overall survival rate between the two groups(74.63%vs.80.89%,Log-rank χ2=1.024,P=0.312).Conclusion For patients with liver cancer undergoing LALR,combined with liver cirrhosis,and high preoperative predictional RLV and SRLV are the independent risk factors influencing early postoperative liver regeneration.Moreover,the higher the patients' postoperative liver regeneration capacity,the lower the tumor-free survival rate.

Objective:To explore the diagnosis and minimal invasive treatment of neonatal pyriform sinus fistula. Methods:A retrospective analysis was conducted on the clinical data of newborns diagnosed with pyriform sinus fistula in the Children's Hospital, Zhejiang University School of Medicine from January 2016 to December 2023, including the diagnostic process and treatment methods. Results:There were 8 children, 2 males and 6 females, with 7 cases on the left side and 1 case on the right side. Six cases revealed a lump in the fetal neck during prenatal examination, and two cases were found to have a neck mass after birth. All cases presented with varying degrees of respiratory disorders. After admission, all patients underwent neck ultrasound and contrast-enhanced CT examination. Neck ultrasound showed cystic masses, with 3 of the cysts accompanied by septa, and an air-fluid level was observed in the cysts in 6 cases from contrast-enhanced CT. All patients underwent ultrasound-guided neck mass puncture and/or tube placement combined with endoscopic electrocauterization. The cystic fluid was found to be yellow and thin, with no signs of infection. The surgical operations were uneventful, and the follow-up time ranged from 12 to 72 months postoperatively. There were no complications such as hoarseness, and no recurrence cases were reported. Conclusion:Neonatal pyriform sinus fistula is often characterized by a large cystic mass in the neck combined with respiratory depression. The presence of an air-fluid level in the cyst from contrast-enhanced CT can be considered an important basis for early diagnosis of pyriform sinus fistula. Ultrasound-guided puncture combined with endoscopic electrocauterization is minimally invasive and safe, making it a suitable minimal invasive treatment for neonatal pyriform sinus fistula.
