Objective To analyze the characteristics of adverse drug reactions （ADR） reported in Sixth People’s Hospital South Campus, Shanghai Jiaotong University from 2021 to 2023, to provide reference for promoting rational clinical drug use. Methods ADR data reported in our hospital were collected retrospectively, including patients’ basic information, drugs causing adverse reactions, types of adverse reactions and outcomes. Descriptive analysis methods were used to summarize and analyze the data. Results A total of 979 cases of ADR were reported in our hospital from 2021 to 2023. The highest proportion of patients with ADR occurred in the age range of 31 to 50, and more male patients （63.5%）. The top five drugs involved with adverse reactions were antibiotics （48.8%）, Chinese medicine injections（19.2%）, vitamins（7.5%）, Chinese traditional medicine（7.2%）, equine tetanus immunoglobulin（6.3%）. Among antibiotics, cefuroxime, ceftazidime and cefotiam were the majority. The organs/systems involved in all ADR were mainly skin and accessories damage （55.4%）. The clinical manifestations were rash, itching, and maculopapular rash. Conclusion From 2021 to 2023, the most common drugs causing adverse drug reactions in our hospital were mainly antibacterial drugs, and the rational clinical use of antibacterial drugs still needs to be concerned.

[Objective] To compare the clinical efficacy of super pulse thulium laser enucleation of the prostate (SPThuLEP) with "open tunnel" and transurethral holmium laser enucleation of the prostate (HoLEP) in the treatment of benign prostatic hyperplasia (BPH), in order to provide reference for the treatment options of BPH. [Methods] The clinical data of 112 BPH patients treated in our hospital during Jan.2023 and Jul.2023 were retrospectively analyzed, including 65 treated with SPThuLEP with "open tunnel" and 57 with HoLEP.The operation time, postoperative hemoglobin decrease, postoperative bladder irrigation, catheter indwelling time, hospitalization time and complications were compared between the two groups.The changes of maximum urine flow rate (Qmax), international prostate symptom score (IPSS), quality of life score (QoL), postvoid residual (PVR) and prostate-specific antigen (PSA) were compared between the two groups before operation and one month after operation. [Results] All operations were successful without conversion to open or transurethral plasmakinetic resection.The postoperative decrease of hemoglobin in SPThuLEP group was lower than that in HoLEP group [(13.12±6.72) g/L vs. (21.02±6.51) g/L], with statistical difference (P<0.05). There were no significant differences in the operation time [(63.35±15.73) min vs.(61.02±17.55) min], postoperative bladder irrigation time [(1.07±0.45) d vs. (1.06±0.36) d], catheter indwelling time [(2.98±0.56) d vs. (3.01±0.63) d] and hospitalization time [(3.63±0.61) d vs.(3.79±0.76) d] between the two groups (P>0.05). No blood transfusion, secondary bleeding or unplanned hospitalization occurred, and there were no serious complications such as transurethral electroresection syndrome (TURS), urethral stricture and urinary incontinence.One month after operation, the Qmax, IPSS, QoL, PVR and PSA of the two groups were significantly improved compared with those before operation (P<0.05), but with no statistical difference between the two groups (P>0.05). [Conclusion] SPThuLEP with "open tunnel" has comparable efficacy as HoLEP in the treatment of BPH.With advantages of small amount of bleeding and high safety, this minimally invasive technique can be widely popularized in clinical practice.

Objective To analyze the relational factors influencing the formation of cauda equina redundant nerve roots(RNRs)of the lumbar spinal stenosis.Methods Clinical data of 116 patients with lumbar spinal stenosis treated from January 2016 to June 2019 were retrospectively analyzed.The patients were divided into redundant nerve roots(RNRs)group and non-RNRs group based on the presence or absence of RNRs on sagittal T2-weighted MRI.In the non-RNRs group,there were 74 patients,including 38 males and 36 females with an average age of(62.00±10.41)years old,the body mass index(BMI)was(23.09±2.22)kg.m-2;the maximum stenosis segment was L2-L3 in 12 cases,L3-L4 in 38,L4-L5 in 20,and L5S1 in 4,respec-tively.In the RNRs group,there were 42 patients,including 18 males and 24 females with an average age of(63.36±8.73)years old,the BMI was(22.63±2.60)kg·m-2;the maximum stenosis segment was L2-L3 in 3 cases,L3-L4 in 9,L4-L5 in 27 and L5S1 in 3,respectively.MRI was performed in the supine position to observe the conshape and morphology of the redundant nerve in the sagittal position.The preoperative low back and leg pain visual analogue scale(VAS),and preoperative Oswestry disability index(ODI)were analyzed,and the rate of spondylolisthesis and ligamentum flavum hypertrophy were compared.Si-multaneously,the inter-vertebral height,intervertebral foramen height,inter-vertebral height+vertebral height,median sagittal diameter at the inter-vertebral space level(DIW-MSD),median sagittal diameter at the pedicel level(DV-MSD),range of mo-tion(ROM)of the stenotic segment were measured and analyzed.Results Among the 116 patients with lumbar spinal stenosis,42 patients developed RNRs,with an incidence of 36.2％.There were no significant differences in gender,age,BMI,preopera-tive VAS for lumbar and leg pain and ODI between two groups(P＞0.05).There were statistically significant differences regard to the duration of symptoms and the rate of spondylolisthesis and ligamentum flavum hypertrophy(P＜0.05);the inter-vertebral height,intervertebral foramen height,inter-vertebral height+vertebral height,DIW-MSD,ROM of the stenotic segment were al-so significantly different between two groups(P＜0.05).However,there was no significant difference in DV-MSD between two groups(P＞0.05).Conclusion The inter-vertebral height,inter-vertebral foramen height,inter-vertebral height+vertebral height,DIW-MSD and ROM of the stenotic segment were the crucial factors related to RNRs in lumbar spinal stenosis.

This study investigated the risk factors for treatment failure in patients with a single infection of Mycobacterium avium.Patients with Mycobacterium avium infection meeting the guidelines for diagnosis and treatment of non-tuberculous mycobacteriosis between January 2016 and December 2020 at Shanghai Pulmonary Hospital were included.A logistic regression model was used to analyze the risk factors for treatment failure.A total of 26(49％)of 53 patients with Mycobacterium avium infection included in the study had treatment failure.A higher proportion of patients with fever,anemia,and lung cavitation in the treatment failure group had significantly higher neutrophils and direct bilirubin,and significantly lower prealbumin.Multi-factorial logistic regression demonstrated that cavitation was an independent risk factor for treatment failure in patients with Mycobacterium avium infection,and Kaplan-Meier analysis indicated significantly lower cumulative 12-month cure rates in pa-tients with cavitation.Patients with Mycobacterium avium infection had a higher rate of treatment failure,and cavitation was found to be a risk factor for treatment failure.Our findings suggest that clinicians should pay attention to the monitoring and treatment of patients with Mycobacterium avium pulmonary cavities to improve the cure rate among patients.

A 49-year-old female examinee, employed at a paper company in Guigang, Guangxi (engaged in the production of napkins), visited the Qintang District People′s Hospital in Guigang on June 11, 2023, to apply for a health certificate. Salmonella was isolated during a physical examination screening for enteric pathogens ( Salmonella, Shigella), and repeated use of empirical antibacterial drugs failed to eradicate the pathogen. A reference laboratory identified the two isolates as S. Kentucky ST198 by performing serotyping, drug resistance phenotyping, and whole genome sequencing. Based on the regional serotype database of Salmonella in China, a phylogenetic tree of S. Kentucky ST198 resistance genotypes was constructed, defining both isolated strains as high-level drug-resistant ST198.2-1 subclade clones. Following a multidisciplinary consultation and based on antimicrobial susceptibility test results, the treatment was adjusted to amoxicillin/clavulanate and azithromycin. On August 19, three consecutive negative test results confirmed the eradication of Salmonella Kentucky.

A 72-year-old female patient was admitted to the emergency department of Qintang District People′s Hospital of Guigang City in August 2023 due to chills and fever, abdominal distension and pain, diarrhea, cough and shortness of breath for 1 day. She had a history of chronic obstructive and pulmonary heart disease, stage Ⅲ hypertension, and ceftazidime allergy. Clinical diagnosis of acute bacterial infection of chronic obstructive pneumonia was made and levofloxacin combined with piperacillin/tazobactam were given as symptomatic treatment. The blood culture reported Campylobacter fetus after four days, and the patient was cured and discharged after seven days with negative blood culture. The morphology and mass spectrometry identification of the strain were consistent with the definition of Campylobacter fetus. Whole genome sequencing predicted the multi-site sequence type as Campylobacter fetus subsp. fetus( Cff) ST20, carrying the tetracycline resistance gene tet (O/M/O), 18 flagella genes (including rpoN gene from Campylobacter jejuni. these genes were not found in the other two Campylobacter fetus subspecies), and six virulence genes (including like-typhoidal toxin and typhoid toxin genes). The pathogen has the ecological characteristics of parasitic farmed animal colonization and the biological characteristics of high mobility and virulence. These attributes facilitated its entry into the bloodstream via the fecal-oral route, leading to invasive infections.

Objective:To explore the mechanism of herb-partitioned moxibustion in relieving rat intestinal inflammation by focusing on the neutrophil extracellular traps(NETs)in Crohn disease(CD)development. Methods:Rats were randomly divided into a normal group,a model group,a herb-partitioned moxibustion group,and a mesalazine group.The CD rat model was prepared with 2,4,6-trinitrobenzene sulfonic acid except for rats in the normal group.Rats in the normal group and model group did not receive any treatment but had the same fixation as the other groups.Rats in the herb-partitioned moxibustion group received herb-partitioned moxibustion at Qihai(CV6)and bilateral Tianshu(ST25).Rats in the mesalazine group received intragastric administration of mesalazine enteric-coated tablets.The general situation of rats in each group was recorded,and the histopathological changes in the colon were observed and scored by hematoxylin-eosin staining.The serum concentrations of NETs DNA(NETs-DNA),neutrophil elastase(NE)-DNA,and myeloperoxidase(MPO)-DNA were detected by ABC enzyme-linked immunosorbent assay,and the citrullinated histone 3(citH3),MPO,and NE protein and mRNA expression levels in rat colon tissue were observed by immunofluorescence and real-time quantitative polymerase chain reaction. Results:Compared with the normal group,the mucosal ulcer reached the muscularis,the epithelium was incomplete,the goblet cells decreased obviously with significant inflammatory cell infiltration in the colon;the colonic mucosa damage index(CMDI)score increased significantly(P<0.01);the serum NETs-DNA,NE-DNA,and MPO-DNA concentrations increased(P<0.05);the NE,citH3,and MPO protein and mRNA expression in the colonic tissue increased significantly in the model group(P<0.01 or P<0.05).Compared with the model group,the mucosal epithelium in the herb-partitioned moxibustion group and the mesalazine group was repaired and the goblet cells increased with a few infiltrating inflammatory cells in the colon;the CMDI score decreased(P<0.01);the serum NETs-DNA,NE-DNA,and MPO-DNA concentrations decreased(P<0.05);the NE,citH3,and MPO protein and mRNA expression in the colonic tissue was down-regulated(P<0.01 or P<0.05). Conclusion:Herb-partitioned moxibustion reduced the serum NETs complex and inhibited the protein and mRNA expression of NETs complex in the colon tissue,which may be one mechanism of herb-partitioned moxibustion in relieving colon mucosal inflammation in CD.

Objective To study the effects of different SBRT-VMAT plans for non-small cell lung cancer(NSCLC)with unilateral ipsilateral double metastatic lesions on received dose,monitor unit(MU),conformity index(CI)and gradient index(GI)of the lung,so as to provide references for therapy planning of the patient above.Methods A total of 11 NSCLC patients with unilateral ipsilateral double metastatic lesions were selected,with three plans developed for each patient by the volumetric modulated arc therapy(VMAT).The inner target areas ITV1 and ITV2 were contoured based on the maximum projection image of the 4D-CT localization mode,which were uniformly expanded externally by 3 mm to obtain the plan target area PTV1 and PTV2,and then PTV1 was added with PTV2 to get PTV12.The first planning mode had the centers of PTV1 and PTV2 target areas as the treatment centers,and two separate plans of plan-1 and plan-2 were developed and then combined into a plan-sum plan for dose evaluation;the second planning mode had the centers of PTV1 and PTV2 target areas as the treatment center,resepctively,and a multicenter plan(plan-D)was formed.The third planning mode had the center of PTV12 target area as the treatment center,and a single-center plan(plan-S)was designed.To meet the requirements of prescribed dose,plan-1 and plan-2 of plan-sum were normalized to PTV1 and PTV2 95％volume and plan-S and plan-D were normalized to PTV 12 95％volume.The three planning modes were compared in terms of received dose,MU,CI and GI of the lung.SPSS 25.0 software was carried out for statistical analysis.Results Plan-S had no significant differences with Plan-sum except V5(P＞0.05),whose V10,V20,V30 and mean dose were significantly lower than those of plan-sum(P＜0.05);plan-D had its received dose and mean dose statistically lower than those of plan-sum(P＜0.05);plan-S and plan-D had no obvious differences in received dose of the lung(P＞0.05).Plan-sum had the CI significantly lower than those of plan-S and plan-D(P＜0.05);plan-S and plan-D had no statistically differences in CI(P＞0.05).Plan-D had the GI significantly lower than plan-S and plan-sum(P＜0.05).Plan-S and plan-sum had no significant differences in GI(P＞0.05).Plan-D and plan-sum had no statistical differences in MU(P＞0.05),which had the MUs significantly higher than that of plan-S(P＜0.05).Conclusion A multicenter planning mode may be used for optimizing dose distribution and enhancing conformity in case the patient can tolerate prolonged immobilization in a fixed position,and a singlecenter planning mode should be adopted to shorten treatment time when the patient is in poor physical conditions.[Chinese Medical Equipment Journal,2024,45(10):49-53]

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective To investigate the risk factors for bronchopulmonary dysplasia(BPD)in twin preterm infants with a gestational age of<34 weeks,and to provide a basis for early identification of BPD in twin preterm infants in clinical practice.Methods A retrospective analysis was performed for the twin preterm infants with a gestational age of<34 weeks who were admitted to 22 hospitals nationwide from January 2018 to December 2020.According to their conditions,they were divided into group A(both twins had BPD),group B(only one twin had BPD),and group C(neither twin had BPD).The risk factors for BPD in twin preterm infants were analyzed.Further analysis was conducted on group B to investigate the postnatal risk factors for BPD within twins.Results A total of 904 pairs of twins with a gestational age of<34 weeks were included in this study.The multivariate logistic regression analysis showed that compared with group C,birth weight discordance of>25%between the twins was an independent risk factor for BPD in one of the twins(OR=3.370,95%CI:1.500-7.568,P<0.05),and high gestational age at birth was a protective factor against BPD(P<0.05).The conditional logistic regression analysis of group B showed that small-for-gestational-age(SGA)birth was an independent risk factor for BPD in individual twins(OR=5.017,95%CI:1.040-24.190,P<0.05).Conclusions The development of BPD in twin preterm infants is associated with gestational age,birth weight discordance between the twins,and SGA birth.
