BACKGROUND:Stand-alone oblique lateral interbody fusion has a high rate of complications of fusion segment sink.Oblique lateral interbody fusion with posterior fixation can provide stable support,but intraoperative position changes and double incisions weaken the advantages of this technique.Oblique lateral interbody fusion combined with lateral plate fixation can achieve one-stage decompression in the same incision,while the lateral internal fixation provides stable support. OBJECTIVE:To analyze the short-term efficacy of oblique lateral interbody fusion combined with lateral plate fixation in the treatment of single-level lumbar degenerative disease. METHODS:The clinical data of 34 patients with single-level lumbar degenerative disease treated with oblique lateral interbody fusion combined with lateral plate fixation were collected from May 2020 to October 2022.Among them,14 were males and 20 were females aged from 41 to 72 years at the mean age of(58.6±9.9)years.There were 11 cases of lumbar spondylolisthesis(Ⅰ°),7 cases of lumbar disc herniation with segmental instability,and 16 cases of lumbar spinal stenosis.Operation time,blood loss,and complications were recorded.Visual analog scale scores of lumbago,radiative pain of both lower limbs,and Oswestry disability index scores were evaluated before surgery,3 months after surgery,and the last follow-up.Dural sac cross-sectional area,intervertebral height,and intervertebral fusion were measured and observed. RESULTS AND CONCLUSION:(1)The 34 patients were followed up for 14-36 months,with an average of(21.3±5.2)months.(2)The operation time ranged from 50 to 92 minutes,with an average of(68.5±11.1)minutes.Intraoperative blood loss was 50-170 mL,with an average of(71.6±25.3)mL.(3)Compared with the preoperative results,the visual analog scale scores and Oswestry disability index scores were significantly decreased at 3 months after surgery and at the last follow-up(P<0.001),and the maximum Oswestry disability index scores were improved by nearly 50％.(4)Bone fusion was achieved in all patients during half-year follow-up.The overall complication rate was 21％(7/34),including 1 case of plate displacement,3 cases of cage subsidence,1 case of psoas weakness,and 2 cases of anterior thigh pain.(5)It is concluded that oblique lateral interbody fusion combined with lateral plate fixation for the treatment of lumbar degenerative diseases has the characteristics of less blood loss,short operation time,rapid postoperative recovery,and significant short-term clinical efficacy with the stable support to a certain extent.The long-term curative effect needs further follow-up observation.

AIM: To investigate the effectiveness and safety of defocus incorporated multiple segments(DIMS)on myopia in adolescents, and provide a theoretical basis for clinical application.METHODS:Retrospective study. A total of 560 myopic children(560 eyes)aged 8-13 years who were admitted to our hospital from January 2019 to January 2022 were selected as research subjects, of whom 180 cases(180 eyes)were enrolled in the DIMS group. The orthokeratology(OK lens)group consisted of 182 patients(182 eyes), and the single vision(SV)group consisted of 198 patients(198 eyes). The changes of the spherical equivalent and axial length in the three groups were observed after 1 and 2 a respectively. The myopia degree(group A: spherical equivalent ≥-3.00 D and group B: -6.00 D≤ spherical equivalent <-3.00 D), and age(group Ⅰ: 8-10 years old and group Ⅱ: 11-13 years old)were grouped to further analyze the effect of myopia degree and age on treatment effect.RESULTS: At 1 and 2 a after wearing lenses, the spherical equivalent in the DIMS and SV groups was statistically significant(all P<0.05); there was statistical significance in the axial length among the DIMS, OK and SV groups(F=21.791, 3.576, all P<0.05). At 1 and 2 a after wearing lenses, there was statistical significance in the changes of spherical equivalent in both the DIMS and SV groups of the groups A and B(all P<0.05); and there was statistical significance in axial length growth of the DIMS, OK and SV groups(all P<0.05). At 1 and 2 a after wearing lenses, there was statistical significance in the changes of spherical equivalent in the DIMS and SV groups of the groups Ⅰ and Ⅱ(all P<0.01); in the group Ⅰ, there was statistical significance in the comparison of axial length growth in the DIMS, OK and SV groups(all P<0.05); in the group Ⅱ, there was no statistical significance in the changes of axial length in the DIMS and OK groups. The efficacy of DIMS and OK in the prevention and treatment of myopia was comparable, and the myopia progression was delayed, and the efficacy was enhanced in those older adolescents wearing DIMS.CONCLUSION: Compared with SV lens, DIMS and OK lenses effectively slow down the myopia progression in adolescents. The overall myopia control effect of DIMS is slightly inferior to that of OK lens. However, with the increase of age and the degree of refractive error, the delaying effect of DIMS on myopia progression is enhanced.

Myelin formation is considered the last true "invention" in the evolution of vertebrate nervous system cell structure. The rapid jumping pulse propagation achieved by myelin enables the high conduction speed that is the basis of human movement, sensation, and cognitive function. As a key structure in the brain, white matter is the gathering place of myelin. However, with age, white matter-associated functions become abnormal and a large number of myelin sheaths undergo degenerative changes, causing serious neurological and cognitive disorders. Despite the extensive time and effort invested in exploring myelination and its functions, numerous unresolved issues and challenges persist. In-depth exploration of the functional role of myelin may bring new inspiration for the treatment of central nervous system (CNS) diseases and even mental illnesses. In this study, we conducted a comprehensive examination of the structure and key molecules of the myelin in the CNS, delving into its formation process. Specifically, we propose a new hypothesis regarding the source of power for myelin expansion in which membrane compaction may serve as a driving force for myelin extension. The implications of this hypothesis could provide valuable insights into the pathophysiology of diseases involving myelin malfunction and open new avenues for therapeutic intervention in myelin-related disorders.

Objective To investigate the prevalence of parasitic infections in market-sold aquatic products in Shanghai Municipality, and to understand the knowledge and practice towards food-borne parasitic diseases among residents, so as to provide insights into the surveillance and control of food-borne parasitic diseases. Methods Freshwater products, seawater products and pickled products were randomly obtained from agricultural trade markets, supermarkets, retail stores and restaurants in Huangpu, Putuo, Minhang and Qingpu districts of Shanghai Municipality from 2020 to 2023. Parasite metacercariae and larvae were detected in these aquatic products using pressing method, digestion method and the dissection method, and the detection of parasitic infection was compared in different types of aquatic products. In addition, the knowledge and practice towards food-borne parasitic diseases were investigated among residents aged 10-80 years old who randomly selected from agricultural trade markets, supermarkets, community streets and other population concentration areas in these four districts by questionnaire in 2023, and the awareness of food-borne parasitic diseases knowledge and percentage of healthy behaviors formation were analyzed. Results A total of 2 109 aquatic products sampled from Huangpu, Putuo, Minhang and Qingpu districts of Shanghai Municipality from 2020 to 2023 were detected, and there were 317 products detected with parasitic infections, with an overall detection rate of 15.03%. There were 8 products detected with parasitic infections in 1 221 freshwater products, with a detection rate of 0.66%, and Clonorchis sinensis was the predominant parasite, which was detected in Pseudorasbora parva, Rhodeus amarus and Carassius auratus. There were 82 products detected with parasitic infections in 501 seawater products, with a detection rate of 16.37%, and Anisakis was the predominant parasite, which was detected in Trichiurus lepturus, Larimichthys polyactis, Pneumatophorus japonicus, Collchthys lucidus, Mugil cephalus, Larimichthys crocea, Scomberomorus niphonius, Stromateoides argenteus and Cololabis saira. There were 227 products detected with parasitic infections in 387 pickled products, with a detection rate of 58.66%, and the prevalence rates of Echinostoma metacercariae were 76.27% (225/295) in Bullacta exarata and 11.11% (2/18) in crab pastes, respectively (χ² = 159.511, P < 0.05). No Paragonimus infection was found in freshwater shrimps, crabs and pickled products, and no Diphyllobothrium latum larvae infection was detected in freshwater and seawater fish. Questionnaire surveys showed that the awareness of food-borne parasitic diseases knowledge was 79.00% (222/281), and the percentages of washing hands before and after meals, not drinking filtered water or tap water directly, not eating raw or semi-raw food, being willing to change special dietary preferences or bad living habits for health, and being willing to learn more about food-borne parasitic diseases knowledge were 99.64% (280/281), 72.24% (203/281), 56.23% (158/281), 96.80% (272/281) and 97.51% (274/281) among residents living in Huangpu, Putuo, Minhang and Qingpu districts, respectively. Conclusions There are food-borne parasite contaminations in market-sold aquatic products in Shanghai Municipality. Although residents are aware of food-borne parasitic diseases knowledge, sustainable surveillance of food-borne parasitic diseases and improved health education are required to minimize the risk of human parasitic infections.

Objective:To investigate the diagnostic value of multi-slice spiral CT(MSCT)perfusion imaging parameters in the differential diagnosis of benign and malignant solitary pulmonary nodules(SPN).Methods:A total of 80 patients with SPN admitted to our hospital from Oct 2021 to Oct 2022 were selected.All patients underwent MSCT perfusion imaging and pathological examination after admission.According to the histopathological examination results,the patients were divided into benign nodule group and malignant nodule group.MSCT perfusion imaging parameters(blood volume,mean transit time,blood flow,surface permeability coefficient)of the two groups were compared.Receiver operating characteristic(ROC)curve was used to analyze the value of MSCT perfusion imaging parameters in the differential diagnosis of benign and malignant SPN.Results:Among the 80 patients with SPN,47 were diagnosed as malignant nodules and 33 as benign nodules by pathological examination.There was no significant difference in mean transit time between 2 groups(P＞0.05).The blood volume,blood flow and surface permeability coefficient in malignant nodule group were higher than those of benign nodule group(P＜0.05).The results of ROC curve showed that the area under the curve(AUC)of blood volume,blood flow and surface permeability coefficient separately and in combination were 0.823(95% CI:0.721-0.926),0.855(95% CI:0.761-0.949),0.850(95% CI:0.752-0.948)and 0.963(95% CI:0.924-1.000)for the diagnosis of benign and malignant SPN,all of which had certain diagnostic value.When blood volume,blood flow and surface permeability coefficient were 4.405 ml/100 g,51.325 ml/(min·100 g)and 21.115 ml/(min·100 g),respectively,the best diagnostic efficiency could be obtained,and the combined diagnosis value was higher.Conclusion:The combination of blood volume,blood flow and surface permeability coefficient of MSCT perfusion imaging parameters have high value in the differential diagnosis of benign and malignant SPN,which can provide effective basis for the early diagnosis and treatment of benign and malignant SPN.

Objective:To explore the influence of social exclusion on the relapse tendency of female drug re-hab patients,and the mediating role of self-esteem and the moderating role of positive psychological capital.Method:A total of 288 female drug rehabilitation patients were selected,and the Social Exclusion Question-naire(SEQ)was used to assess the degree of social exclusion experienced by the patients.The Relapse Tendency Questionnaire(RPQ)was used to evaluate the current tendency of drug relapse.The Rosenberg Self-Esteem Scale(RSES)was used to evaluate the self-esteem level of the patients,and the Positive Psychological Capital Question-naire(PPCQ)was used to evaluate their level of positive psychological capital.Results:The SEQ scores of female drug rehab patients were positively correlated with the RPQ scores(β=0.41,P＜0.001),The RSES scores had a mediating effect between the scores of SEQ and RPQ,with a mediation effect size of 0.09(95％CI:0.04-0.15,accounting for 20.6％of the total effect).The PPCQ scores had a moderating effect between the scores of RSES and RPQ(β=-0.08,P＜0.05)and between the scores of SEQ and RPQ(β=0.10,P＜0.05).Conclusion:So-cial exclusion could not only directly affect but also indirectly affect the relapse tendency through self-esteem of fe-male drug rehab patients.Positive psychological capital could moderate the relationship between social exclusion,self-esteem,and relapse tendency.

Objective To report and analyze the clinical characteristics of kidney transplant recipients(KTRs)combined with novel coronavirus Omicron variant strain infection of novel coronavirus(SARS-CoV-2),and to investigate the possible factors affecting the serum creatinine change.Methods The patients under-going allogeneic kidney transplantation and complicating Omicron variant strain infection in this hospital from October 2022 to December 2023 were retrospectively observed.Their clinical data,basic complications and prognosis,etc.were collected and analyzed.The possible factors affecting the serum creatinine change were an-alyzed.Results Among the 114 cases of KTRs combined with Omicron variant strain infection included in this study,there were 90 cases(78.9％)in the home management group(group A),18 cases(15.8％)in the non-intensive isolation ward group(group B)and 6 cases(5.3％)in the ICU group(group C).The most common symptoms were in turn fever(90.4％),fatigue(65.8％)and cough(61.4％),the clinical manifesta-tions were mainly upper respiratory tract infection symptoms.The overall mortality rate was 2.6％(3/114),moreover the dead patients all were in the group C.The number of basic comorbidities in the group C was higher than that in the group B and group A(P＜0.05).The patients were re-divided into 33 cases(28.9％)in the creatinine increase group(group D),71 cases(62.3％)in the creatinine unchange group(group E)and 10 cases(8.8％)in the creatinine decrease group(group F).The patients in the F group were the patients with mild and moderate Omicron variant strain infection in the group A,and a larger proportions of the pa-tients in the group D and group F discontinued or reduced the calcineurin inhibitor(CNI)type drugs than in the group E.Conclusion The hazard of Omicron variant strains to KTRs has been greatly reduced compared with previous other variant strains.Realizing the immune balance between anti-infection and anti-rejection is the effective measure for preventing renal function damage in KTRs.

Background:Previous studies have proved that neutrophil gelatinase-associated lipocalin(NGAL)plays an important role in the progression of Crohn's disease(CD),and may serve as a potential biomarker for disease activity prediction,severity assessment,treatment response evaluation and prognosis monitoring.However,the diagnostic value of NGAL in perianal fistulizing Crohn's disease(pfCD)is still unclear.Aims:To investigate the serum level of NGAL and its diagnostic value in patients with active pfCD.Methods:A total of 66 patients diagnosed as pfCD from July 2021 to June 2023 at Longhua Hospital,Shanghai University of Traditional Chinese Medicine were enrolled,including 36 active pfCD patients and 30 inactive pfCD patients.The disease activity and perianal fistula activity were assessed by Crohn's disease activity index(CDAI)and perianal disease activity index(PDAI),respectively.Serum NGAL,fecal calprotectin(FC),C-reactive protein(CRP),erythrocyte sedimentation rate(ESR),as well as CDAI score and PDAI score were compared between the active and inactive pfCD patients,and the correlations of NGAL with the other parameters in active pfCD patients were analyzed.ROC curve was drawn to evaluate the values of serum NGAL,FC,CRP and ESR for diagnosis of active pfCD.Results:The serum NGAL,FC,CRP,ESR,CDAI score and PDAI score in active pfCD patients were significantly higher than those in inactive pfCD patients(all P＜0.001).NGAL was positively correlated with FC(r=0.64,P＜0.001),CRP(r=0.55,P＜0.001),ESR(r=0.53,P＜0.001),CDAI score(r=0.59,P＜0.001)and PDAI score(r=0.54,P＜0.001)in active pfCD patients.The optimal cut-off values of NGAL,FC,CRP and ESR were 220.5 μg/L,146.0 μg/g,7.9 mg/L and 23.5 mm/h,respectively,for the diagnosis of active pfCD,and the area under the curve were 0.922(95％CI:0.850-0.995),0.888(95％CI:0.806-0.970),0.853(95％CI:0.763-0.944)and 0.830(95％CI:0.731-0.930),respectively.Conclusions:Serum NGAL level is associated with the disease activity of pfCD,and can be used as a non-invasive biomarker for the clinical diagnosis of active pfCD.

Inhibiting the death receptor 3(DR3)signaling pathway in group 3 innate lymphoid cells(ILC3s)pre-sents a promising approach for promoting mucosal repair in individuals with ulcerative colitis(UC).Paeoniflorin,a prominent component of Paeonia lactiflora Pall.,has demonstrated the ability to restore barrier function in UC mice,but the precise mechanism remains unclear.In this study,we aimed to delve into whether paeoniflorin may promote intestinal mucosal repair in chronic colitis by inhibiting DR3 signaling in ILC3s.C57BL/6 mice were subjected to random allocation into 7 distinct groups,namely the control group,the 2％dextran sodium sulfate(DSS)group,the paeoniflorin groups(25,50,and 100 mg/kg),the anti-tumor necrosis factor-like ligand 1A(anti-TL1A)antibody group,and the IgG group.We detected the expression of DR3 signaling pathway proteins and the proportion of ILC3s in the mouse colon using Western blot and flow cytometry,respectively.Meanwhile,DR3-overexpressing MNK-3 cells and 2％ DSS-induced Rag1-/-mice were used for verification.The results showed that paeoniflorin alleviated DSS-induced chronic colitis and repaired the intestinal mucosal barrier.Simultaneously,paeoniflorin inhibited the DR3 signaling pathway in ILC3s and regulated the content of cytokines(interleukin-17A,granulocyte-macrophage colony stimulating factor,and interleukin-22).Alternatively,paeoniflorin directly inhibited the DR3 signaling pathway in ILC3s to repair mucosal damage indepen-dently of the adaptive immune system.We additionally confirmed that paeoniflorin-conditioned me-dium(CM)restored the expression of tight junctions in Caco-2 cells via coculture.In conclusion,paeoniflorin ameliorates chronic colitis by enhancing the intestinal barrier in an ILC3-dependent manner,and its mechanism is associated with the inhibition of the DR3 signaling pathway.
