Hepatocellular carcinoma （HCC） is a common malignant tumor with a high mortality rate， an insidious onset， and complex pathological mechanisms. In the tumor microenvironment， tumor-promoting immune cells protect tumor cells from immune attacks， while dysfunction of anti-tumor immune cells causes the inhibition of immune response， thereby leading to the continuous deterioration of cancer. In recent years， traditional Chinese medicine has shown good efficacy in the treatment of HCC， and it can inhibit the proliferation and metastasis of cancer cells by regulating immune cells. By analyzing related articles in China and globally， this article summarizes how immune cells affect the progression of HCC through the immunosuppressive pathway and how traditional Chinese medicine exerts an anti-HCC effect by regulating immune cells， in order to provide theoretical basis and reference for optimizing the treatment of HCC.

ObjectiveTo investigate the pathogenic spectrum and epidemiological characteristics of diarrheal disease in Fengxian District of Shanghai, and to provide scientific basis for the prevention and control of diarrheal diseases. MethodsBasic information of the initial adult cases visited diarrheal disease surveillance sentinel hospital in Fengxian District, Shanghai, was collected from August 2013 to 2023, and fecal samples were collected at 1∶5 sampling intervals to isolate and identify 5 kinds of diarrheagenic Escherichia coli (DEC), Salmonella (SAL), Vibrio parahaemolyticus, Campylobacter, Vibrio cholerae, Shigella and Yersinia enterocolitica (YE). Simultaneously, nucleic acid detection was performed for 3 kinds of rotavirus, 2 kinds of norovirus, intestinal adenovirus, astrovirus and sapovirus. ResultsA total of 1 861 cases of newly diagnosed diarrheal disease were reported, with the peak in July to August. Additionally, 704 surveillance samples were detected, with a total positive detection rate of 50.57%. The detection rates of bacterial, viral and mixed infection were 25.14%, 21.02% and 4.40%, respectively. Among the pathogens detected, DEC accounted for the highest (17.61%, 124/704), followed by norovirus (16.48%, 116/704), rotavirus (6.39%, 45/704), SAL (5.97%, 42/704) and Campylobacter (3.84%, 27/704). DEC detected were mainly enteroaggregative Escherichia coli and enterotoxigenic Escherichia coli, with no detection of Vibrio cholerae, Shigella and YE. The highest total pathogen detection rate was observed from June to September, and the detection peaks of norovirus were from March to June and from October to December, whereas that of DEC was from June to October. The detection rate of rotavirus peaked from January to February, but which was not detected between 2020‒2023. The SAL positive rate peak was in September, whereas that of Campylobacter was from July to September. ConclusionThe main pathogens detected in Fengxian District from 2013‒2019 are DEC, norovirus, rotavirus, SAL and Campylobacter. Different pathogens have different detection peaks, with bacteria predominating in summer and viruses in winter and spring. Prevention and control measures should be carried out according to the epidemiological characteristics of different seasons.

Multiple system atrophy （MSA） is a rare degenerative disease of the nervous system and has diverse and atypical clinical manifestations， and it overlaps with other diseases in α-synuclein spectrum disease. There are great challenges in the diagnosis and early differential diagnosis of the disease， and missed diagnosis and misdiagnosis occur from time to time， thereby delaying the treatment of the disease.Videonystagmography （VNG） is currently the main noninvasive test used to assess vestibular function and can provide different eye movement parameters. Studies have shown the presence of abnormal eye movements in patients with MSA. From the perspective of vision-eye movement， this article reviews the current status of research on eye movements in patients with MSA and reveals the internal connection between them， in order to provide an important reference for the early diagnosis of MSA.

OBJECTIVE To provide a reference for pharmaceutical care in patients with ulcerative colitis （UC） and ankylosing spondylitis （AS） who developed pustular psoriasis induced by infliximab. METHODS Clinical pharmacists participated in the pharmaceutical care process of a patient with UC and AS who developed pustular psoriasis after using infliximab. The clinical pharmacists determined， using Naranjo’s Scale， that the correlation between the patient’s pustular psoriasis and infliximab was “likely”. Regarding the patient’s development of pustular psoriasis after using infliximab， the clinical pharmacists recommended discontinuing infliximab and switching to Upadacitinib extended-release tablets. For the patient’s skin allergic reaction after using upadacitinib， the clinical pharmacists advised continuing the use of upadacitinib and closely monitoring any potential adverse reactions during the treatment period. RESULTS The clinicians adopted the clinical pharmacists’ recommendation. Following the treatment， the patient’s symptoms were significantly alleviated， and the patient was discharged with medication. The follow-up after discharge showed that the treatment was effective and well-tolerated. CONCLUSIONS The clinical pharmacists analyzed the causal relationship between infliximab and pustular psoriasis. Through pharmaceutical care measures such as dynamic monitoring of skin lesions， evaluation of treatment responses， and optimization of drug regimens， they assisted the physicians in formulating an individualized medication plan， ensuring the safety and efficacy of the patient’s medication use.

Objective　To analyze the epidemiological characteristics and infection pathways and virulence factors of one cholera outbreak in Fengxian District, Shanghai, China, in 2024, and to provide scientific basis for epidemic control and prevention. Methods　Epidemiologic data of cases of one cholera outbreak in Fengxian District in 2024 were collected using on-site epidemiologic survey methods; RT-PCR nucleic acid testing and bacterial culture were applied to carry out pathogenicity testing of cases, close contacts, environment, and food samples; and the genome sequences of the strains were obtained using second-generation gene sequencing. Results　The case was a 62-year-old woman, who presented to the doctor with diarrhea for 4 consecutive days, 4-5 times a day, with watery stools, which was not effectively relieved by self-administered medication. There was no history of traveling away from Shanghai for 5 days before the onset of the disease, and she was engaged in the preparation and delivery of food for rural banquets during the period. Vibrio cholerae O139 was detected in the anal swab sample of the case and the septic tank of the workplace on the 4th day after the onset of the disease; samples of turtle and links in the store selling turtle were cultured for Vibrio cholerae O139. The isolate carried several virulence-related genes such as ctxA, ctxB, HlyA, zot, rtxA, hapA, nanH, tdh, and T3SS. Comparison of the isolate with the O139 strain of cholera cluster within our country through the National Pathogenic Bacteria Recognition Network (NPBN) in recent years suggests that the closest environmental or aquatic animal isolate to the sequence of this strain is the turtle isolate uploaded at a place in Guangdong. Conclusion　This outbreak was a disseminated outbreak caused by the case's contact with turtle contaminated with Vibrio cholerae O139, and early detection of enteric infectious diseases such as cholera can be achieved by relying on the outpatient enteric cholera surveillance network.

OBJECTIVE: To establish a three-dimensional finite element model of a digital wire loop space maintainer for the mandible and primary tooth loss, in order to investigate the stress, deformation, and shear force experienced by patients with the loss of the second primary molar when wearing the wire loop space maintainer. METHODS: Cone beam computed tomography (CBCT) scans were performed on the patients to create a digital model of the mandible with the absence of the second primary molar using Mimics 21.0 software. A digital model integrating the crown's retention and the wire loop structure of the full crown and ring wire loop space maintainer was constructed using pediatric space maintainer design software, utilizing three different materials: cobalt-chromium alloy, polyether ether ketone (PEEK), and titanium alloy. In ANSYS Work Beach 2023 R2 software, vertical loads of 70 N, tilted 45° along the long axis of the tooth loads of 70 N, and a 10 N load on the surface of the wire loop were applied to the occlusal surfaces of models 46 and 84, simulating centric and lateral occlusions during chewing with the wire loop space maintainer in place. The stress states of the wire loop space maintainer and supporting teeth were analyzed. RESULTS: Under various loading conditions, the maximum principal stress of the ring wire loop space maintainer was significantly lower than that of the full crown. Stress contour maps indicated that the peak of the maximum principal stress occurred at the junction of the wire loop and crown structure, indicating that this area was more susceptible to fracture. The ring wire loop space maintainer made from PEEK material exhibited the lowest maximum shear stress on the internal organizational surfaces, with equivalent stresses of 23.18 MPa and 36.35 MPa for models 46 and 84, respectively. Stress contour maps demonstrated that the maximum stress on tooth 46 was located at its mesial, while the maximum stress on tooth 84 was situated near the root area on its distal, in contact with the wire loop space maintainer. CONCLUSION In cases of second primary molar loss, wearing the digital ring wire loop space maintainer can effectively distribute stress, and the ring wire loop space maintainer made from PEEK material reduces the stress experienced by supporting teeth to some extent, demonstrating its superiority in clinical application.

Objective:To investigate the molecular characteristics and clinical heterogeneity of Usher syndrome（USH） -related gene variants in patients with hereditary hearing loss in southwest China, providing a basis for early diagnosis and clinical management. Methods:Thirteen patients from twelve families with hearing loss who attended the Affiliated Children's Hospital of Kunming Medical University between January 2017 and March 2021 were enrolled. All patients were identified as carrying USH-related gene variants through next-generation sequencing. Sanger sequencing was performed for all patients and their parents to validate the pathogenic variants. Comprehensive clinical evaluations, including medical history collection, otologic and ophthalmologic examinations, and vestibular function assessments, were conducted. Results:Among the 13 patients, 4 were diagnosed with USH type 1 and 2 with USH type 2. A total of 19 pathogenic or likely pathogenic variants were detected in USH-related genes, including MYO7A,CDH23,USH1C, and USH2A. The causative gene was MYO7A in 3 probands, CDH23 in 5, USH1C in 3, and USH2Ain 2. All patients exhibited an autosomal recessive inheritance pattern. Vestibular dysfunction was observed in 4 patients, and retinitis pigmentosa（RP） in 3 patients. Based on the genotype-phenotype correlation, 6 patients were initially diagnosed with USH, while 7 were classified as having non-syndromic hearing loss（NSHL）. Conclusion:This study revealed the clinical heterogeneity of USH-related gene variants in patients with hereditary deafness in southwest China. Although the clinical manifestations of USH are complex and there are overlapping characteristics between different subtypes, genetic testing provides an important basis for early diagnosis and precise clinical management. Especially for those with typical hearing loss, early genetic diagnosis can provide a window of time for early detection and intervention of retinitis pigmentosa.

Objective:To compare the pregnancy and neonatal outcomes of in vitro fertilization-embryo transfer(IVF-ET)with fresh or frozen embryos in spouses of patients with severely low sperm concentration and motility.Methods:A total of 2300 patients whose spouses have severely low sperm concentration and motility underwent IVT-ET in the Reproduction Medicine Center,Sir Run Run Shaw Hospital from April 2018 to April 2022.After applying the propensity score matching(PSM),473 fresh embryo transferred cycles and 473 frozen embryo transferred cycles were selected for the study,and the pregnancy and neonatal outcomes were compared between the two groups.Results:There were no significant differences in pregnancy outcomes and neonatal outcomes between fresh and frozen embryo groups(all P＞0.05).In the stratification analysis,the number of retrieved oocytes in the fresh good-quality embryo transfer group was significantly increased compared with the fresh poor-quality embryo group(P＜0.05),but the very early pregnancy loss rates were similar between the two groups(P＞0.05),while the rate in fresh good-quality embryo transfer group was significantly higher than that in the frozen good-quality embryo transfer group(P＜0.05).Among different age groups of women,the number of retrieved oocytes and the level of estrogen in the fresh embryo transfer group was significantly higher in the 20 to＜30 years old group than that in the 30 to＜35 years old group(both P＜0.05),but the clinical pregnancy rate was lower in the 20 to＜30 years old group than that in the 30 to＜35 years old group(P＞0.05).Additionally,the very early pregnancy loss was significantly increased in the fresh embryo group compared with the frozen embryo group in the 20 to＜30 years age group(P＜0.05).Conclusions:There were no significant differences in pregnancy and neonatal outcomes between fresh and frozen embryo transfer in spouses of patients with severely low sperm concentration and motility undergoing IVF-ET.Due to the shorter transfer times,less embryo freezing damage and reduced costs,fresh embryo transfer can be considered as the first choice.However,it is not necessary to pursue fresh embryo transfer if maternal oestrogen levels are too high and there is a tendency of overstimulation.

Objective To investigate the expression of miR-30a-5p and miR-129-5p in the serum of patients with non-small cell lung cancer after EGFR targeted therapy and their relationship with the therapeutic effect.Methods A total of 186 patients with non-small cell lung cancer who received EGFR targeted therapy in our hospital from January 2020 to June 2022 were regarded as research objects.According to the efficacy of patients,they were separated into effective group(n=141)and ineffective group(n=45).The serum levels of miR-30a-5p and miR-129-5p were compared between the two groups;multivariate logistic regression was applied to analyze the factors influencing the efficacy of non-small cell lung cancer;receiver operating characteristic was applied to analyze the predictive value of serum miR-30a-5p,miR-129-5p levels for efficacy of non-small cell lung cancer.Results There were obvious differences in smoking history and TNM stage between the ineffective group and the effective group(P＜0.05).The expression levels of miR-30a-5p and miR-129-5p in the ineffective group were obviously lower than those in the effective group(P＜0.05).Multivariate logistic regression analysis showed that serum miR-30a-5p,miR-129-5p,smoking history,and TNM stage were all factors influencing the efficacy of non-small cell lung cancer(P＜0.05).Receiver operating characteristic showed that the AUC of the combination of serum miR-30a-5p and miR-129-5p to predict the efficacy of non-small cell lung cancer was 0.926,the sensitivity was 91.11％,and the specificity was 83.69％,which was better than their respective predictions(Z combination-miR-30a-5P=3.260,Zcombination-miR-129-5p=3.726,P=0.001,0.000).Conclusion The serum levels of miR-30a-5p and miR-129-5p in patients with non-small cell lung cancer who failed to respond to EGFR targeted therapy are obviously lower than those in the effective group;The combination of the two has a good predictive value for the efficacy of non-small cell lung cancer after EGFR targeted therapy.
