OBJECTIVE To explore the role of clinical pharmacists in identifying paroxysmal spasms caused by drugs， and provide reference for rational drug use. METHODS Retrospective analysis was conducted on pharmaceutical care provided by clinical pharmacists for a patient with ceftazidime-avibactam （CZA-AVI） induced paroxysmal spasms. The clinical pharmacists identified， analyzed and summarized the clinical manifestations， risk factors and treatment methods of the nervous system toxicity caused by antibacterial drugs. According to the patient’s clinical symptoms and test results， the clinical pharmacists recommended temporarily discontinuing the use of polymyxin B and montelukast sodium， and halving the dose of CZA-AVI. The physicians did not adopt the recommendation to halve the dose of CZA-AVI， and when the patient’s neurologic toxicity did not improve， the clinical pharmacists again recommended discontinuing CZA-AVI， which was accepted by the physicians. RESULTS Clinical pharmacists analyzed the condition and checked related drugs that caused paroxysmal spasms of extremities one by one， and finally determined that CZA-AVI might be the drug that caused paroxysmal spasms of extremities in the patient. After stopping the drug， the patient’s symptoms improved and was transferred to a community hospital for rehabilitation treatment. CONCLUSIONS The dose of CZA-AVI should be adjusted according to the renal function and the neurotoxicity should be guarded against， especially for patients with advanced age， renal insufficiency， and the combined use of multiple drugs related to nephrotoxicity and neurotoxicity.

Purpose To evaluate the differential diagnostic value of conventional ultrasound in the ureteral polyps and ureteral carcinoma via continuous observation.Materials and Methods The conventional ultrasound of patients with ureteral polyps and ureteral carcinoma treated in Shaanxi Provincial People's Hospital were retrospectively analyzed from June 2015 to June 2022.According to the pathological results,all participants were divided into the ureteral polyp group(98 cases)and the ureteral carcinoma group(151 cases).All clinical and ultrasound data were recorded,and the differences of echo,blood flow and peristalsis were compared between the two groups.Results There were significant differences in ureteral peristalsis,color Doppler flow distribution,periureteral tissue thickening,increased echo,and hydronephrosis(χ2=197.50,138.89,26.97,36.13,all P<0.05)between the two groups.Low echo was predominant in both groups[67(68.37)vs.114(75.50)],with no significant difference(χ2=1.52,P>0.05).In the ureteral polyp group,67 cases were found in the upper ureter,89 cases were observed continuously with common peristalsis,and 73 cases with color blood flow were mostly central blood flow,while in the ureteral cancer group,85 cases were found in the middle and lower ureter,148 cases showed almost no peristalsis,and 122 cases with color blood flow were mostly peripheral blood flow.Conclusion There are some differences in clinical features such as the location as well as whether hydronephrosis between ureteral polyps and carcinoma.Peristalsis can provide the differential diagnosis for ureteral polyps and ureteral carcinoma via continuous observation.

Objective:To systematically retrieve, evaluate, and summarize evidence on insomnia screening and assessment in adult malignant tumor patients.Methods:The clinical decisions, guidelines, and expert consensus on screening and assessing insomnia in malignant tumor patients were systematically searched in clinical decision support systems, guideline websites, literature databases, and professional association websites. This study conducted methodological quality evaluation and evidence extraction, translation, and integration.Results:A total of 8 articles were included, including three clinical decisions, two evidence-based guidelines, and three expert consensuses. After extracting and summarizing evidence, 38 pieces of evidence were obtained from three aspects of general management principles, insomnia screening, and insomnia assessment.Conclusions:The insomnia screening and assessment in adult malignant tumor patients should be standardized according to evidence-based standards and combined with specific clinical situations in China.

Background::Carotid intima-media thickness (IMT) and diameter, stiffness, and wave reflections, are independent and important clinical biomarkers and risk predictors for cardiovascular diseases. The purpose of the present study was to establish nationwide reference values of carotid properties for healthy Chinese adults and to explore potential clinical determinants.Methods::A total of 3053 healthy Han Chinese adults (1922 women) aged 18-79 years were enrolled at 28 collaborating tertiary centers throughout China between April 2021 and July 2022. The real-time tracking of common carotid artery walls was achieved by the radio frequency (RF) ultrasound system. The IMT, diameter, compliance coefficient, β stiffness, local pulse wave velocity (PWV), local systolic blood pressure, augmented pressure (AP), and augmentation index (AIx) were then automatically measured and reported. Data were stratified by age groups and sex. The relationships between age and carotid property parameters were analyzed by Jonckheere-Terpstra test and simple linear regressions. The major clinical determinants of carotid properties were identified by Pearson’s correlation, multiple linear regression, and analyses of covariance.Results::All the parameters of carotid properties demonstrated significantly age-related trajectories. Women showed thinner IMT, smaller carotid diameter, larger AP, and AIx than men. The β stiffness and PWV were significantly higher in men than women before forties, but the differences reversed after that. The increase rate of carotid IMT (5.5 μm/year in women and 5.8 μm/year in men) and diameter (0.03 mm/year in both men and women) were similar between men and women. For the stiffness and wave reflections, women showed significantly larger age-related variations than men as demonstrated by steeper regression slopes (all P for age by sex interaction <0.05). The blood pressures, body mass index (BMI), and triglyceride levels were identified as major clinical determinants of carotid properties with adjustment of age and sex. Conclusions::The age- and sex-specific reference values of carotid properties measured by RF ultrasound for healthy Chinese adults were established. The blood pressures, BMI, and triglyceride levels should be considered for clinical application of corresponding reference values.

Objective:To explore the influence of pancreatic stents of different lengths on the incidence of post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP).Methods:Data of 299 patients with biliary tract diseases who received endoscopic retrograde cholangiopancreatography (ERCP) and 5 Fr prophylactic pancreatic stents placement at the First Affiliated Hospital of Air Force Medical University from January 2013 to January 2022 were retrospectively analyzed. Patients were divided into the short-stent group (<5 cm, n=163) and the long-stent group (>5 cm, n=136). Baseline data, intraoperative procedures, and postoperative outcomes were compared between the two groups and propensity score matching (PSM) was used for complementary analysis. The primary endpoint was the incidence of PEP. The risk factors for PEP in patients with prophylactic pancreatic stents placement was explored by logistic regression analysis . Results:The overall PEP incidence was 11.0% (33/299). There was no significant difference in the PEP incidence [11.7% (19/163) VS 10.3% (14/136), χ 2=0.140, P=0.708], moderate-to-severe PEP incidence [1.8% (3/163) VS 2.2% (3/136), χ 2=0.000, P=1.000], or spontaneous stent dislodgement rate within two weeks [81.7% (103/126) VS 78.4% (87/111), χ 2=0.421, P=0.516] between the two groups. After PSM, 123 patients were included in each group, and the overall PEP incidence was 8.9% (22/246). There was no significant difference in PEP incidence [8.9% (11/123) VS 8.9% (11/123), χ 2=0.000, P=1.000], moderate-to-severe PEP incidence [0.8% (1/123) VS 1.6% (2/123), χ 2=0.000, P=1.000], or spontaneous stent dislodgement rate within two weeks [80.6% (75/93) VS 78.6% (77/98), χ 2=0.126, P=0.722] between the two groups. Logistic regression analysis showed that normal liver function ( OR=2.36, 95% CI:1.01-5.51, P=0.046) and failed bile duct cannulation ( OR=7.51, 95% CI:2.18-25.96, P=0.001) were independent risk factors for PEP in patients with biliary tract diseases who received prophylactic pancreatic stents placement. Conclusion:Longer 5 Fr pancreatic stents (>5 cm) do not further reduce the overall risk of PEP or moderate-to-severe PEP compared with 5Fr-5 cm stent. Normal liver function and failure of bile duct intubation were independent risk factors for PEP after prophylactic pancreatic stent placement in patients with biliary diseases.

ObjectiveTo optimize and establish a multiplex polymerase chain reaction （PCR） system to simultaneously identify Ziziphi Spinosae Semen （ZSS），Hovenia acerba semen （HAS），and Ziziphi Mauritianae Semen （ZMS）， etermine their content to solve the problem of adulteration of ZSS pieces and its preparations. MethodAfter the analysis and comparison of the internal transcribed spacer （ITS） sequence differences of ZSS and its adulterants，specific single nucleotide polymorphism （SNP） sites were found，and specific primers for identification were designed. The samples of ZSS，HAS， and ZMS from different sources were specifically amplified under the conditions of optimized annealing temperature，the number of cycles， and concentration of primers，as well as different polymerases and PCR systems after evaluation. Identification was carried out according to the size of specific amplification bands，and the lower limit of detection （LOD） and adulteration LOD were studied. ResultWhen the annealing temperature was 63 ℃ and the number of cycles was 23，549，169，389 bp specific bands were amplified from ZSS，HAS， and ZMS. The lower LOD of this method was 0.24 ng and 1.2 ng for ZSS and HAS， respectively. The adulteration LOD for ZSS，HAS， and ZMS was 0.5%，2%， and 2% respectively. ConclusionThe established multiplex allele-specific PCR identification method can accurately identify ZSS，HAS， and ZMS at the same time，which can provide a basis for solving the problem of adulteration of ZSS and references for controlling the quality，security， and clinical application of ZSS.

Objective:To assess the combination of conventional ultrasound with contrast-enhanced ultrasound(CEUS)in the diagnosis of urothelial carcinoma(UC)of the renal pelvis in elderly patients.Methods:Sixty-seven elderly patients with a histopathologic diagnosis of UC of the renal pelvis and surgically treated at our hospital between April 2015 and March 2023 were retrospectively analyzed.Characteristics of regular preoperative 2D ultrasound, color Doppler flow imaging(CDFI)and CEUS were examined.Results:Of 67 patients, 49(73.13%)were found to have localized lesions in the renal pelvis and renal calyces.Lesions in 53 patients(79.10%)could be clearly identified by conventional ultrasound, with 46(86.79%)being isoechoic or hypoechoic, and 7(13.21%)being hyperechoic.Analysis of tumor blood flow by CDFI found 22 cases(41.51%)with avascular lesions, 21(39.62%)with hypovascular lesions and 10(18.87%)with hypervascular lesions.The average value of the resistance index(RI)was 0.64.Enhancement was seen in 62 lesions(92.54%)by CEUS after injection of SonoVue.Compared with the cortex of the ipsilateral kidney, a slow enhancement pattern was observed in 46(74.19%), 14(22.58%)showed simultaneous enhancement, and 2(3.23%)showed fast enhancement.At peak enhancement, 43 lesions(69.35%)had hypo-enhancement, 10(16.13%)had iso-enhancement, and 9(14.52%)had hyper-enhancement, compared with the cortex.Concerning the homogeneity of enhancement, 16(25.81%)displayed heterogeneous enhancement, with tumor necrosis or hemorrhage, and 46(74.19%)had homogeneous enhancement.When the contrast agent washout rate was assessed, a fast washout pattern was observed in 53(85.48%), synchronous washout in 6(9.68%), and slow washout in 3(4.84%).Conclusions:UC of the renal pelvis mostly shows isoechoic and hypoechoic lesions on conventional ultrasound, avascular or hypo-vascular lesions on CDFI, and slow-in, fast-out and hypo-enhancement on CEUS, compared with the cortex.Conventional ultrasound combined with CEUS can help improve the diagnostic accuracy of UC of the renal pelvis.

Objective:To compare the knowledge of endoscopic screening of gastrointestinal cancers between digestive healthcare workers and new chatbots (chatGPT and new Bing).Methods:A test with twenty-three questions of endoscopic screening of gastrointestinal cancers was conducted, focusing on the appropriate age of screening, high-risk factors, the follow-up time, and the advantages and risks of digestive endoscopy. Digestive healthcare workers were invited to complete the test through electronic questionnaires. New Bing and chatGPT were used to answer each question for 10 rounds. The primary endpoint was the correct rate of all answers. The answer accuracy between digestive healthcare workers and new chatbots were compared using variance analysis, and the factors that affected the accuracy of the answers in digestive healthcare workers were explored using univariate and multivariable liner regression analysis.Results:The results of the test completed by 76 digestive healthcare workers (21 residents, 28 digestive nurses, and 27 digestive doctors) were analyzed. The accuracies were 36.4%±10.9%, 34.5%±10.2%, 52.2%± 12.6%, 46.3%±9.8% and 67.1%±9.3% in residents, digestive nurses, digestive doctors, chatGPT, and new Bing, respectively, with significant difference ( F=22.6, P<0.001). The accuracy was highest in new Bing ( P<0.001). The accuracy was comparable between chatGPT and digestive doctors (LSD- t=-1.398, P=0.166), and both higher than that of digestive nurses (LSD- t=2.956, P=0.004; LSD- t=5.955, P<0.001) and residents (LSD- t=2.402, P=0.018; LSD- t=4.951, P<0.001). Furthermore, the accuracy was comparable between digestive nurses and residents (LSD- t=-0.574, P=0.567). Compared with new Bing, digestive doctors had lower accuracy in answering questions related to adverse events of screening, follow-up recommendation of intestinal metaplasia, high risk factors and screening methods for colon cancer ( P<0.05), but higher accuracy in answering questions related to endoscopic adverse events and screening methods for esophageal cancer ( P<0.05). Multivariable liner regression analysis showed that being digestive doctors ( β=11.7, t=3.054, P=0.003) and questionnaire response time (≥7.6 min) ( β=7.8, t=2.894, P=0.005) were independent factors for the answer accuracy of digestive healthcare workers. Conclusion:Compared with digestive healthcare workers, New chatbots—new Bing has higher accuracy in answering gastrointestinal cancer screening-related questions, but performs poorly in answering questions such as adverse events of endoscopy and screening methods for esophageal cancer.

Objective:To investigate the effect of autologous hematopoietic stem cell transplantation (auto-HSCT) bridging to chimeric antigen receptor T cell (CAR-T) immunotherapy for follicular lymphoma (FL) transformed to B-lymphoblastic leukemia/lymphoma (B-LBL).Methods:The diagnosis and treatment of 1 patient with FL transformed to B-LBL admitted to the First Hospital of Soochow University in August 2020 were retrospectively analyzed and the literature was reviewed.Results:The male patient was 65 years old, and was diagnosed as FL (stage Ⅳ group A, FL international prognostic index -1 score 3 points, high-risk group) in August 2020. And then he was given 6 courses of RB (rituximab combined with bendamustine) regimen, with complete remission (CR) at mid-term and end-stage PET-CT, followed by regular maintenance therapy with rituximab every 2 months, and disease progressed after 4 courses of maintenance therapy. According to the results of histopathology and bone marrow aspiration in December 2021, he was diagnosed B-LBL involving the bone marrow. Partial remission was achieved after induction therapy with zanubnulindb combined with hyper CVAD (cyclophosphamide + doxorubicin + vindesine + dexamethasone) regimen, followed by auto-HSCT bridging to CAR-T treatment targeting CD19 and CD22, which proceeded smoothly with cytokine release syndrome grade 0, immune effector cell-associated neurotoxicity syndrome grade 0. The patient successfully underwent hematopoietic reconstruction and orally taken ibrutinib after discharge. PET-CT indicated CR 2 months after transplantation and he was still in disease-free survival state.Conclusions:The prognosis of FL transformed to B-LBL is poor, and auto-HSCT bridging to CAR-T can improve the prognosis and prolong the survival time of patients who cannot undergo allogeneic hematopoietic stem cell transplantation.

To explore the pharmacogenomic markers that affect the platinum-based chemotherapy response in non-small-cell lung carcinoma (NSCLC), we performed a two-cohort of genome-wide association studies (GWAS), including 34 for WES-based and 433 for microarray-based analyses, as well as two independent validation cohorts. After integrating the results of two studies, the genetic variations related to the platinum-based chemotherapy response were further determined by fine-mapping in 838 samples, and their potential functional impact were investigated by eQTL analysis and in vitro cell experiments. We found that a total of 68 variations were significant at P < 1 × 10^-3 in cohort 1 discovery stage, of which 3 SNPs were verified in 262 independent samples. A total of 541 SNPs were significant at P < 1 × 10^-4 in cohort 2 discovery stage, of which 8 SNPs were verified in 347 independent samples. Comparing the validated SNPs in two GWAS, ADCY1 gene was verified in both independent studies. The results of fine-mapping showed that the G allele carriers of ADCY1 rs2280496 and C allele carriers of rs189178649 were more likely to be resistant to platinum-based chemotherapy. In conclusion, our study found that rs2280496 and rs189178649 in ADCY1 gene were associated the sensitivity of platinum-based chemotherapy in NSCLC patients.
