OBJECTIVE To investigate the use of drugs and the development of pharmaceutical care in the tight medical alliance （shorted for “medical alliance”） of Wanzhou District of Chongqing， and provide reference for the further construction of the medical alliance. METHODS A survey form was designed and distributed to 21 constituent units （5 leading units and 16 member units） of 5 medical alliances in Wanzhou District of Chongqing. The statistical analysis was conducted in aspects of basic drug allocation and use， pharmaceutical personnel team construction， the development of pharmaceutical care， and rational use of antibiotics. RESULTS Among the 21 constituent units， 4 leading units and 14 member units achieved the target for the proportion of essential drug procurement varieties， with a total compliance rate of 85.71%； 4 leading units and 13 member units achieved the target for the proportion of national essential drug allocation and usage amount， with a total compliance rate of 80.95%. The proportions of personnel with doctoral degrees in the 5 leading units and 16 member units were 1.71% and 0 respectively， and the proportions of personnel with senior professional titles were 8.56% and 1.63%， respectively. A total of 5 pharmacy or pharmaceutical combined outpatient clinics were set up in the 21 medical alliance units， and 5 clinical pharmacy information service platforms were established； all 5 leading units were able to regularly carry out clinical pharmacy projects， while only 4 out of 16 member units had conducted medical order review and evaluation. The proportions of irrational use of antibiotics in outpatient prescriptions and inpatient medical records of the 16 member units （4.81%， 5.21%） were significantly higher than those of the 5 leading units （2.80%， 4.00%）. CONCLUSIONS The allocation and usage of national essential drugs in 21 constituent units from Wanzhou District of Chongqing are both in good standing. However， the data on the allocation of pharmaceutical professionals and the number， qualifications， and job titles of clinical pharmacists in member units are generally low. Moreover， the pharmaceutical service projects and service quality in member units need to be further improved.

Radiochemotherapy-induced oral mucositis (OM) is a common oral complication in patients with tumors following head and neck radiotherapy or chemotherapy. Erosion and ulcers are the main features of OM that seriously affect the quality of life of patients and even the progress of tumor treatment. To date, differences in clinical prevention and treatment plans for OM have been noted among doctors of various specialties, which has increased the uncertainty of treatment effects. On the basis of current research evidence, this expert consensus outlines risk factors, clinical manifestations, clinical grading, ancillary examinations, diagnostic basis, prevention and treatment strategies and efficacy indicators for OM. In addition to strategies such as basic oral care, anti-inflammatory and analgesic agents, anti-infective agents, pro-healing agents, and photobiotherapy recommended in previous guidelines, we also emphasize the role of traditional Chinese medicine in OM prevention and treatment. This expert consensus aims to provide references and guidance for dental physicians and oncologists in formulating strategies for OM prevention, diagnosis, and treatment, standardizing clinical practice, reducing OM occurrence, promoting healing, and improving the quality of life of patients.

Objective:To measure the retinal structural and functional parameters of adult Macaca fascicularis, and explore the similarity of the retinal structural and functional parameters between non-human primates and normal human retinas.Methods:Six eyes of 3 5-year-old adult Macaca fascicularis were examined by in vivo detection including color fundus photography, retinal optical coherence tomography (OCT) and electroretinogram (ERG) to determine the thickness of the inner/outer retina at the fovea and 1 000/2 000 μm away from the nasal, temporal, superior and inferior regions of the fovea, the thickness of the retinal nerve fiber layer (RNFL), the area of optic disc, the area of optic cup, the area ratio of cup to disc and the biological parameters of flash ERG.Differences in the above parameters between left and right eyes were analyzed.The similarity of parameters between Macaca fascicularis and human was compared with reference to published literature.The use and care of animals complied with the Regulation on the Management of Experimental Animals.The study protocol was approved by the Institutional Animal Care and Use Committee of Hubei Topgene Biotechnology (NO.IACUC-2019-012). Results:The foveal thickness, optic disc area, cup-disc area ratio, and average RNFL thickness in normal adult Macaca fascicularis were (252.31±4.79)μm, (1.89±0.05)mm 2, 0.14±0.01, and (103.53±0.58)μm, respectively.The b-wave amplitude of dark-adapted 0.01 ERG was (66.75±7.29)μV.The a- and b-wave amplitudes of dark-adapted 3.0 ERG response were (57.15±15.01) and (122.10±25.51)μV, respectively.The a- and b-wave amplitudes, the amplitude of oscillation potentials, and the latency of dark-adapted 10.0 ERG response were (72.98±20.14)μV, (131.67±13.78)μV, (49.98±10.08)μV, and (30.02±5.76)ms, respectively.The a- and b-wave amplitudes of light-adapted 3.0 ERG were (9.16±2.75) and (40.43±5.57)μV, respectively.The latency and the amplitude of the light-adapted 30 Hz flicker was (26.61±1.19)ms and (24.72±5.10)μV, respectively.There was no significant difference in the parameters between left and right eyes (all at P>0.05). The retinal thickness in central fovea, mean RNFL thickness, waveform and amplitude of ERG of Macaca fascicularis were similar to normal human. Conclusions:The structure and function of the retina of adult Macaca fascicularis are similar to those of normal humans.As a laboratory animal for preclinical drug research, in vivo studies of Macaca fascicularis can refer to normal human retinal parameters.

ObjectiveTo determine the antibody levels of varicella-zoster virus （VZV） in healthy individuals aged 1 to 30 years in Songjiang District of Shanghai， and to provide evidence for further development of varicella immunization strategies for healthy population. MethodsSix village committees were selected in Songjiang District through multi-stage stratified random sampling method from July to September 2022. Healthy individuals aged 1 to 30 years old in these villages were recruited and 3‒5 mL of venous blood was collected. Anti-VZV IgG antibody was tested by ELISA. Positive rate of anti-VZV IgG antibody and geometric mean concentration （GMC） were determined. ResultsA total of 315 healthy individuals aged （10.97±8.38） years were included in this study， of which 165 were males aged （11.00±8.52） years and 150 were females aged （10.96±8.25） years. Blood samples were collected and tested for anti-VZV IgG antibody， with the overall positive rate of 55.24% （174/315）. The GMC was calculated to be 99.73 mIU·mL^-1， with the GMC in those tested positive for anti-VZV IgG antibody of 413.11 mIU·mL^-1. The positive rate of anti-VZV IgG antibody and GMCs across age groups ranged between 13.33%‒86.67% and 16.36‒355.14 mIU·mL^-1， respectively. The highest GMC was found in the group of 20‒30 years old （355.14 mIU·mL^-1）， followed by 132.41 mIU·mL^-1 in the group of 5‒ years old and 138.12 mIU·mL^-1 in the group of 15‒ years old. Moreover， the positive rate was 38.47% in the group with 1-dose varicella vaccine and 63.49% in the group with 2 doses， while the GMC were 53.28 mIU·mL^-1 and 130.79 mIU·mL^-1 in these two groups， respectively. Multivariable analysis revealed that occupation was a risk factor associated with anti-VZV IgG antibody （OR=2.540）. Stratified analysis by varicella immunization history showed that among 2-dose vaccination group， time interval since the last dose was a protective factor （OR=0.315）. ConclusionsThe overall positive rate of anti-VZV IgG antibody in healthy population in Songjiang District of Shanghai remains low. The 2-dose varicella vaccination should be strengthened to improve the coverage in susceptible population.

Vaccination is the most economical and effective measure to prevent infectious diseases targeted by vaccines. Despite this， the safety of vaccines has garnered increased attention due to recent vaccine incidents. The tetravalent human papillomavirus vaccine （HPV） is one of the effective means to prevent cervical cancer and in situ adenocarcinoma caused by infection with corresponding serotypes. The inactivated novel coronavirus vaccine is an emergency vaccine developed to prevent novel coronavirus infection after the COVID-19 outbreak， and is also the main measure used to control the spread of COVID-19 at present. The monitoring data show that both vaccines have good safety after inoculation， but due to individual differences and other reasons， rare reactions may occur in a very small number of recipients. This article presents two cases of urticaria vasculitis following inoculation of the tetravalent HPV and the novel corona virus inactivated vaccine.

Objective:To investigate the characteristics of gene mutations in angioimmunoblastic T-cell lymphoma (AITL).Methods:Seventy-five AITL cases diagnosed at the Department of Pathology, Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine, Shanghai, China from June 2021 to June 2023 were included. Their formalin-fixed and paraffin-embedded or fresh tissues were subject to targeted next generation sequencing (NGS). The sequencing data was collected, and the distribution and type of gene mutations were analyzed.Results:492 potential driver mutations were identified in 74 out of the 84 genes. Targeted sequencing data for the 75 AITL patients showed that the genes with mutation frequencies of ≥10% were TET2 (89.3%), RHOA (57.3%), IDH2 (37.3%), DNMT3A (36.0%), KMT2C (21.3%), PLCG1 (12.0%), and KDM6B (10.7%). There were significant co-occurrence relationships between TET2 and RHOA, TET2 and IDH2, and RHOA and IDH2 gene mutations ( P<0.05), respectively, while TET2 and KDM6B gene mutations were mutually exclusive ( P<0.05). Conclusions:The study reveals the mutational characteristics of AITL patients using NGS technology, which would provide insights for molecular diagnosis and targeted therapy of AITL.

Objective This study aimed to identify differentially methylated genes (DMGs) associated with natural killer cells in patients with autoimmune thyroiditis (AIT),focusing on the influence of varying water iodine exposure levels. Methods Participants were divided into categories based on median water iodine (MWI) concentrations:iodine-fortified areas (IFA,MWI<10 μg/L),iodine-adequate areas (IAA,40 ≤ MWI ≤ 100μg/L),and iodine-excessive areas (IEA,MWI>300 μg/L). A total of 176 matched AIT cases and controls were recruited and divided into 89,40,and 47 pairs for IFA,IAA,and IEA,respectively. DMGs were identified using 850K BeadChip analysis for 10/10 paired samples. Validation of DNA methylation and mRNA expression levels of the DMGs was conducted using MethylTarget? and QRT-PCR for 176/176 paired samples. Results KLRC1,KLRC3,and SH2D1B were identified as significant DMGs. Validation revealed that KLRC1 was hypomethylated and highly expressed,whereas KLRC3 was hypermethylated and highly expressed in individuals with AIT. Furthermore,KLRC1 was hypomethylated and highly expressed in both IFA and IEA. Conclusion The DNA methylation status of KLRC1 and KLRC3 may play crucial roles in AIT pathogenesis. Additionally,DNA methylation of KLRC1 seems to be influenced by different iodine concentrations in water.

Objectives:To investigate the clinical value of contrast echocardiography in the detection of right heart space-occupying lesions. Methods:The imaging and clinical data of 39 patients with right heart space-occupying lesions confirmed by surgery,pathology and clinical treatment in Yanbian University Hospital from January 2019 to January 2023 were retrospectively analyzed.All patients underwent contrast echocardiography and cardiac magnetic resonance(CMR)examinations.The contrast echocardiography features of right heart neoplastic from non-neoplastic occupying lesions were summarized.The diagnostic efficacy of contrast echocardiography and CMR in right heart space-occupying lesions was compared. Results:Among the 39 patients,12 patients(30.8%)were confirmed as thrombus and vegetation,6 patients(15.4%)as benign tumors and 21 patients(53.8%)as malignant tumors.There were 8,4,4 and 17 patients of thrombus,vegetation,benign tumor and malignant tumors located in right atrium,respectively.Contrast echocardiography was used to diagnose thrombus and vegetation in 12 patients(30.8%),benign tumors in 5 patients(12.8%),malignant tumors in 22 patients(56.4%).CMR was used to diagnose thrombus and vegetation in 18 patients(46.2%),benign tumors in 5 patients(12.8%),malignant tumors in 16 patients(41.0%).The Kappa coefficient between contrast echocardiography and clinical diagnosis was 0.956(P<0.001).The Kappa coefficient between CMR and clinical diagnosis was 0.754(P<0.001). Conclusions:Contrast echocardiography can dynamically observe the degree of vascularization in the lesion tissue in real-time,accurately distinguishing the nature of the right heart space-occupying lesions.

Objective:To explore the relevancy between the uridine diphosphate-glucuronylgly-cosyltransferase 1A1 (UGT1A1) gene mutation and the phenotype of indirect hyperbilirubinemia in children.Methods:Sixteen cases with indirect hyperbilirubinemia who visited the Department of Gastroenterology, Children's Hospital of Nanjing Medical University from July 2013 to November 2019 were retrospectively analyzed and were divided into Gilbert syndrome (GS), Crigler-Najjar syndrome type II (CNS-II), and indirect hyperbilirubinemia groups unexplained by UGT1A1 gene mutations. The differences in gene mutation site information and general clinical data were compared. The association between gene mutation spectrum and bilirubin level was explored by t-test analysis.Results:Ten of the sixteen cases with indirect hyperbilirubinemia had GS, three had CNS-II, and three had indirect hyperbilirubinemia unexplained by UGT1A1 gene mutations. A total of six mutation types were detected, of which c.211G?>?A accounted for 37.5% (6/16), c.1456T?>?G accounted for 62.5% (10/16), and TATA accounted for 37.5% (6/16), respectively. Compared with the GS group, the CNS group had early disease onset incidence, high serum total bilirubin ( t ?=?5.539, P ??0.05) and age of onset ( t ?=?0.3611, P ?>?0.05) between the two groups. There was no significant correlation between the number of UGT1A1 gene mutations and serum bilirubin levels. Children with c.1456T?>?G homozygous mutations had the highest serum bilirubin levels. Conclusion:The common pathogenic variants of the UGT1A1 gene sequence are c.1456T?>?G, c.211G?>?A, and TATA, indicating that these site mutations are related to the occurrence of indirect hyperbilirubinemia and have important guiding significance for the etiological analysis of indirect hyperbilirubinemia in children.
