ABSTRACT

Objective:To explore the differences of fecal calprotectin (FC), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) between colon and small intestinal Crohn′s disease, and their predictive values for disease activity and mucosal healing in patients with small intestinal Crohn′s disease.Methods:From January 2017 to January 2023, 64 patients with Crohn′s disease who underwent capsule endoscopy in the First Affiliated Hospital of Zhejiang Chinese Medical University were enrolled, among them 28 patients had only small intestinal lesions (small intestine group) and 36 patients had lesions involving both small intestine and colon or only colon involvement (ileocolon group). The FC, CRP, and ESR levels of the two groups were detected and compared 15 days before capsule endoscopy examination. Wilcoxon rank-sum test was used for statistical analysis. Receiver operating characteristic curve analysis was used to evaluate the predictive value of FC, CRP, and ESR for disease activity and mucosal healing in patients with small intestinal Crohn′s disease.Results:The FC, CRP, and ESR levels of the small intestine group during the active phase of the disease were 1 689.00 μg/g (727.75 μg/g, 1 800.00 μg/g), 5.67 mg/L (1.00 mg/L, 17.01 mg/L), and 4.50 mm/1 h (2.00 mm/1 h, 11.00 mm/1 h), respectively; while FC, CRP, and ESR levels during the mucosal healing phase were 112.00 μg/g (46.50 μg/g, 130.50 μg/g), 1.00 mg/L (1.00 mg/L, 1.62 mg/L), and 2.00 mm/1 h (2.00 mm/1 h, 5.50 mm/1 h), respectively. The FC, CRP, and ESR levels of the ileocolon group during the active phase of the disease were 1 800.00 μg/g (895.50 μg/g, 1 800.00 μg/g), 4.94 mg/L (3.10 mg/L, 14.80 mg/L), and 10.00 mm/1 h (2.00 mm/1 h, 27.75 mm/1 h), respectively, while FC, CRP, and ESR levels during the mucosal healing phase were 66.00 μg/g (32.50 μg/g, 97.50 μg/g), 1.00 mg/L (1.00 mg/L, 1.55 mg/L), and 2.00 mm/1 h (2.00 mm/1 h, 4.50 mm/1 h), respectively. There were no statistically significant differences in FC, CRP, and ESR between the small intestine group and the ileocolon group during the active phase of the disease and mucosal healing phase (all P> 0.05). In the small intestine group, the levels of FC and CRP of patients during the active phase of the disease were 1 173.00 μg/g (312.00 μg/g, 1 800.00 μg/g) and 2.10 mg/1 L (1.00 mg/L, 16.00 mg/L), which were both higher than those of patients during the mucosal healing phase (112.00 μg/g (46.50 μg/g, 130.50 μg/g) and 1.00 mg/L (1.00 mg/L, 1.62 mg/L)), and the differences were statistically significant ( Z=-4.35 and-2.67, P<0.001 and =0.008). In the small intestine group, the level of ESR of patients during the active phase of the disease was 4.00 mm/1 h (2.00 mm/1 h, 16.00 mm/1 h), and there was no significant difference compared with that of patients during the mucosal healing phase (2.00 mm/1 h (2.00 mm/1 h, 5.50 mm/1 h)) ( P>0.05). When the cut-off level of FC was 188.50 μg/g, the sensitivity, specificity, and area under the curve for predicting disease activity in patients with small intestinal Crohn′s disease was 93.3%, 100.0%, and 0.964, respectively. When the cut-off value of CRP was 3.12 mg/L, the sensitivity, specificity, and area under the curve for predicting disease activity in patients with small intestinal Crohn′s disease was 46.7%, 92.3%, and 0.744, respectively. When the cut-off level of ESR was 10.00 mm/1 h, the sensitivity, specificity, and area under the curve for predicting disease activity in patients with small intestinal Crohn′s disease was 33.3%, 100.0%, and 0.654, respectively. There were no statistically significant differences in the area under the curve between the combinations of FC and CRP, FC and ESR, FC, CRP and ESR, and FC alone for predicting disease activity in patients with small intestinal Crohn′s disease (0.964, 0.959, and 0.959 vs. 0.964, all P> 0.05). There was a statistically significant difference in the area under the curve between the combination of CRP and ESR and FC alone in predicting disease activity in patients with small intestinal Crohn′s disease (0.708 vs. 0.964, Z=-2.57, P=0.010). Conclusions:There are no statistically significant differences in FC, CRP, and ESR between colon and small intestinal Crohn′s disease. FC has a high predictive value for disease activity and mucosal healing in patients with small intestinal Crohn′s disease and has certain clinical application value.

ABSTRACT

Objective: To exploring the clinical features of SF3B1-mutated myelodysplastic syndrome with excess blasts (MDS-EB) and analyzing the association between SF3B1 mutation, and efficacy and prognostic significance for patients with MDS-EB. Methods: This was a retrospective case series study. The clinical data of 266 patients with MDS-EB diagnosed in the First Affiliated Hospital of Zhengzhou University between April 2016 and November 2021 were analyzed. The observed indicators included blood routine counts, mutated genes, overall response rate (ORR), overall survival (OS), progression-free survival (PFS), and leukemia-free survival (LFS). The Kaplan-Meier method was used to depict the survival curves. The Log-rank test method was equally used to compare survival across groups and performed the Cox proportional hazard regression model for prognostic analysis. Results: In 266 patients with MDS-EB, 166 (62.4%) were men, and the median age was 57 (17-81) years. Moreover, there were included 26 and 240 patients in the SF3B1-mutated and SF3B1 wild-type groups. Patients in the SF3B1-mutated group were older [median age 65 (51, 69) years vs. 56 (46, 66) years, P=0.033], had higher white blood cell (WBC) counts [3.08 (2.35, 4.78) × 109/L vs. 2.13 (1.40, 3.77) × 109/L], platelet (PLT) counts [122.5 (50.5, 215.0) ×109/L vs. 49.0 (24.3, 100.8) × 109/L], absolute neutrophil counts (ANC) [1.83 (1.01, 2.88) × 109/L vs. 0.80 (0.41, 1.99) × 109/L]and occurrence of DNMT3A mutation [23.1% (6/26) vs. 6.7% (16/240)] (all P<0.05). The ORR were similar in both groups after 2 and 4 cycles of therapy (P=0.348, P=1.000). Moreover, the LFS (P=0.218), PFS (P=0.179) and OS (P=0.188) were similar across the groups. Univariate Cox analysis revealed that SF3B1 mutation did not affect the prognosis of patients with MDS-EB (OS: P=0.193; PFS: P=0.184). Conclusions: Patients with SF3B1 mutation were older, with greater WBC, PLT, and ANC, and SF3B1 mutation easily co-occurred with DNMT3A mutation. From this model, there were no significant differences in efficacy and survival of MDS-EB with or without SF3B1 mutation.

ABSTRACT

Abstract Bone morphogenetic protein 9 (BMP9) tends to be associated with various inflammatory responses of diseases, but its relationship with pulpitis remains unknown. Objective This study aimed to evaluate the effects and mechanisms of BMP9 in pulpitis. Methodology A rat model of pulpitis was used to evaluate the expression of BMP9, which was also analysed in Porphyromonas gingivalis lipopolysaccharide (Pg-LPS)-stimulated human dental pulp cells (hDPCs). The effects and mechanism of BMP9 on the regulation of inflammatory factors and matrix metalloproteinase-2 (MMP2) were evaluated using real-time quantitative PCR, western blotting, and immunocytofluorescence. Moreover, the migration ability of THP-1 monocyte-macrophages, treated with inflammatory supernate inhibited by BMP9, was previously tested by a transwell migration assay. Finally, a direct rat pulp capping model was used to evaluate in vivo the influence of the overexpression of BMP9 in pulpitis. Results The expression of BMP9 decreased after 24 h and increased after 3 and 7 d in rat pulpitis and inflammatory hDPCs. The overexpression of BMP9 inhibited the gene expression of inflammatory factors (IL-6, IL-8, and CCL2) and the secretion of IL-6 and MMP2 in Pg-LPS-stimulated hDPCs. The level of phosphorylated Smad1/5 was upregulated and the levels of phosphorylated ERK and JNK were downregulated. The inflammatory supernate of hDPCs inhibited by BMP9 reduced the migration of THP-1 cells. In rat pulp capping models, overexpressed BMP9 could partially restrain the development of dental pulp inflammation. Conclusion This is the first study to confirm that BMP9 is involved in the occurrence and development of pulpitis and can partially inhibit its severity in the early stage. These findings provided a theoretical reference for future studies on the mechanism of pulpitis and application of bioactive molecules in vital pulp therapy.

ABSTRACT

The clinical data of a case with late-onset isolated sulfite oxidase deficiency(ISOD)admitted in the Department of Neurology, Children′s Hospital, Zhejiang University School of Medicine in July 2021 were retrospectively analyzed.Fifteen previously published cases of late-onset ISOD were also reviewed.The patient was a girl, who was hospitalized because of " motor regression with mental retardation for 5 days" at 1 year old.The manifestations of the patient were extrapyramidal symptoms, regression of motor development and seizures.The level of urinary sulfites in the patient was increased.Magnetic resonance imaging (MRI) features were bilateral pallidus and substantia nigra.Gene sequencing suggested a pure missense mutation of the sulfite oxidase( SUOX) gene c. 650(exon5)G>A(p.Arg217Gln). In 16 cases of late-onset ISOD, the median age at onset and diagnosis was 10.5 months and 34.0 months, respectively.The common clinical manifestations were hypotonia (13 cases), seizures (10 cases), movement disorders (9 cases), and ectopia lentis (6 cases). The most common brain MRI feature was pallidus changes (11 cases), followed by lesions of substantia nigra (5 cases), and cerebral atrophy (4 cases). Fourteen cases of late-onset ISOD showed a positive urinary sulfite test.The missense mutation of the SUOX gene was found in 9 cases.It suggested that brain MRI involvement of bilateral pallidus, high excretion of urine sulfites and the missense mutation of the SUOX gene were important diagnostic clues for late-onset ISOD.

ABSTRACT

Objective:To investigate the pathogenesis and prognosis of transformation of primary myelofibrosis (PMF) to B-cell acute lymphoblastic leukemia (B-ALL).Methods:The diagnosis and treatment process of a patient transferred from PMF to B-ALL in Affiliated Tumor Hospital of Zhengzhou University in November 2018 were retrospectively analyzed, and the relevant literature was reviewed.Results:The patient was a 64-year-old female, she was initially diagnosed with PMF, and then she developed B-ALL 17 months later after receiving treatment of prednisone, danazole, levamisole, aspirin, thalidomide and jaktinib. After induction therapy, the patient received 8 months of continuous remission, and then the reexamination showed relapse. There was no remission after reinduction therapy. The patient gave up treatment and was discharged 2 months later. JAK2 V617F gene mutation was positive before and after leukemia transformation.Conclusions:The patients with transformation of PMF to B-ALL have poor clinical prognosis and short survival time. The possible mechanism of its transformation may be related to additional genetic events or certain high-risk genes. However, the specific mechanism is still unclear, and further investigation of the etiology is needed to seek targeted treatment.

ABSTRACT

Methods:The clinical data of a CNSL patient with pancytopenia caused by intrathecal injections of chemotherapeutic agents in the First Affiliated Hospital of Zhengzhou University in January 2017 were retrospectively analyzed, and the related literature was reviewed.Results:The patient was a 71-year-old man who was diagnosed with acute myeloid leukemia. During regular chemotherapy, he suffered from extramedullary relapse, and leukemic cells invaded the superior sagittal sinus of brain. Lumbar puncture and intrathecal injections of chemotherapeutic agents were given intermittently. During this period, the complete blood count of patient progressively declined, and oral mucositis appeared. After calcium folinate rescue and intermittent blood transfusion, the complete blood count recovered. Eventually, the patient developed bone marrow relapse and died of infection.Conclusions:On the one hand, the invasion of leukemia cells into the central nervous system leads to increased intracranial pressure and accelerated absorption of cerebrospinal fluid; on the other hand, it induces the structural damage of the superior sagittal sinus or increased permeability, and therefore chemotherapy agents continue to enter the blood with cerebrospinal fluid, which may be the cause of pancytopenia.

ABSTRACT

In this study,a fluorescent(FL)aptasensor was developed for on-site detection of live Salmonella typhimurium(S.T.)and Vibrio parahaemolyticus(V.P.).Complementary DNA(cDNA)of aptamer(Apt)-functionalized multicolor polyhedral oligomeric silsesquioxane-perovskite quantum dots(cDNA-POSS-PQDs)were used as encoded probes and combined with dual-stirring-bar-assisted signal amplification for pathogen quantification.In this system,bar 1 was labeled with the S.T.and V.P.Apts,and then bar 2 was functionalized with cDNA-POSS-PQDs.When S.T.and V.P.were introduced,pathogen-Apt complexes would form and be released into the supernatant from bar 1.Under agitation,the two complexes reached bar 2 and subsequently reacted with cDNA-POSS-PQDs,which were immobilized on MXene.Then,the encoded probes would be detached from bar 2 to generate FL signals in the supernatant.Notably,the pathogens can resume their free state and initiate next cycle.They swim between the two bars,and the FL signals can be gradually enhanced to maximum after several cycles.The FL signals from released encoded probes can be used to detect the analytes.In particular,live pathogens can be distinguished from dead ones by using an assay.The detection limits and linear range for S.T.and V.P.were 30 and 10 CFU/mL and 102-106 CFU/mL,respectively.Therefore,this assay has broad application potential for simultaneous on-site detection of various live pathogenic bacteria in water.

ABSTRACT

Consecutively hospitalized patients with confirmed coronavirus disease 2019 (COVID-19) in Wuhan, China were retrospectively enrolled from January 2020 to March 2020 to investigate the association between the use of renin-angiotensin system inhibitor (RAS-I) and the outcome of this disease. Associations between the use of RAS-I (angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB)), ACEI, and ARB and in-hospital mortality were analyzed using multivariate Cox proportional hazards regression models in overall and subgroup of hypertension status. A total of 2771 patients with COVID-19 were included, with moderate and severe cases accounting for 45.0% and 36.5%, respectively. A total of 195 (7.0%) patients died. RAS-I (hazard ratio (HR)= 0.499, 95% confidence interval (CI) 0.325-0.767) and ARB (HR = 0.410, 95% CI 0.240-0.700) use was associated with a reduced risk of all-cause mortality among patients with COVID-19. For patients with hypertension, RAS-I and ARB applications were also associated with a reduced risk of mortality with HR of 0.352 (95% CI 0.162-0.764) and 0.279 (95% CI 0.115-0.677), respectively. RAS-I exhibited protective effects on the survival outcome of COVID-19. ARB use was associated with a reduced risk of all-cause mortality among patients with COVID-19.

ABSTRACT

With the continuous advancement of the deepening reform of the medical security system, the medical insurance payment method, as an important part of it, has become the focus of the reform. As one of the main types of innovative payment methods, payment for performance combines payment and medical service quality to improve the efficiency of medical and health services and patient satisfaction. In order to accelerate the clinical application of new medical technologies, improve patients′ access to innovative technologies, and reduce the disease economic burden of patients, Shanghai has carried out a pilot reform of paying for performance for three new technologies including Cryoablation in the treatment of cancer, Da Vinic Robotic Surgical System and Plasma MicroRNA Panel detection. Through multiple rounds of expert consultation and on-the-spot investigation, the positive detection rate, complication rate and tumor reduction rate were finally determined as the performance evaluation indicators of the three technologies, and the corresponding payment standards were defined. The pilot reform in Shanghai could provide reference for other regions to carry out performance based payment.

ABSTRACT

Objective:To investigate the motor and non-motor symptoms and polysomnographic features in patients with rapid eye movement sleep behavior disorder (RBD), early Parkinson's disease (PD) with and without RBD.Methods:Patients with idiopathic RBD (IRBD) and early PD were collected from the clinics in West China Hospital of Sichuan University from August 2020 to May 2021.All the patients were divided into 3 groups including IRBD group (67 cases), PD with RBD (PD+ RBD) group (19 cases), and PD without RBD (PD-RBD) group (22 cases). Unified Parkinson's disease rating scale part 3 (UPDRS-Ⅲ), Hoehn-Yahr(H-Y) stage, Epworth sleepiness scale (ESS), REM sleep behavior disorder questionnaire-Hong Kong (RBDQ-HK), 17-item Hamilton depression scale(HAMD-17), mini-mental state examination(MMSE), Sniffin’Sticks olfactory function test, visual analogue scale (VAS), and scale for outcomes in Parkinson's disease-AUT(SCOPA-AUT) were used to assess the motor and non-motor symptoms including sleepiness, RBD, depression, cognitive function, olfactory function, pain and autonomic function respectively.All patients were performed to the polysomnography (PSG) examination.One-way ANOVA, Krukal-Wallis test, χ2 test and Fisher accurate test were used to analyze the data of motor and non-motor symptoms and sleep parameters among the 3 groups accordingly. Results:There were statistically significant differences in motor symptoms among the three groups ( F=57.009, P<0.05), and the scores of UPDRS Ⅲ and H-Y stage were higher in the PD+ /- RBD group than those in the IRBD group(both P<0.05). However, there was no significant difference in motor symptoms between PD+ RBD group and PD-RBD group ( P>0.05). There were no significant differences in the scores of ESS, MMSE, olfactory function test and VAS (all P>0.05). But the HAMD-17 score was significantly higher in the PD+ RBD group(2(1, 9)) than that in the IRBD group (0(0, 3)( P<0.05). The SCOPA-AUT scores of autonomic function were significant differences in the three groups, mainly in the digestive system, urinary system, and sexual function ( P<0.05). Notably, the IRBD group (8(4, 14)) and PD+ RBD group (11(7, 14)) had higher scores of SCOPA-AUT compared with PD-RBD group (4(4, 5.75)(all P<0.05), especially in the digestive dysfunction(all P<0.05). The PD+ RBD group(3.47±1.17) had higher scores of sexual function compared with IRBP group(1.78±0.60)( P<0.05), and the urinary system scores also higher than PD-RBD group( P<0.05). The PD-RBD group(21.30 (6.10, 34.00)/h) had a significantly higher oxygen desaturation index in REM sleep compared with that of IRBD group(5.90(2.70, 16.73)/h) ( P<0.05). Conclusions:Early PD with RBD has more severe non-motor symptoms, especially depression and autonomic dysfunction.RBD can be related with the earlier and more widely autonomic dysfunction.

ABSTRACT

OBJECTIVE@#To establish a quantitative evaluation parameter system for basic acupuncture manipulations based on 3D motion tracking technology, and to further analyze the characteristics of acupuncture manipulation.@*METHODS@#The motion tracking system Simi Motion Ver.8.5 was used to collect parameters of acupuncture manipulations, so as to establish a quantitative evaluation system mainly in spatial control parameters, time control parameters and stability parameters. Based on the evaluation parameter system, data of acupuncture manipulations (even reinforcing-reducing manipulation using lifting-thrusting technique and twirling technique) were collected from 19 teachers majored in acupuncture-moxibustion, of which the characteristics were analyzed and were compared with the results tested by traditional ATP-Ⅱ acupuncture manipulation parameter determination apparatus (ATP-Ⅱ).@*RESULTS@#The evaluation parameter system could quantitatively analyze the basic acupuncture manipulations in 3 aspects, i.e. space, time and stability. Acupuncture manipulations were performed by shifting the needle body in a certain range along X, Y and Z axes. The amplitude and speed of thumb movement were greater than those of index finger. The time-history of lifting was similar to thrusting, while the time-history of twirling to left was similar to twirling to right in even reinforcing-reducing manipulation. The coordinate-time curve of finger movement of the evaluation system had consistent wave pattern compared with the voltage-time curve generated by ATP-Ⅱ.@*CONCLUSION@#The quantitative evaluation parameter system based on 3D motion tracking technology can objectively evaluate basic acupuncture manipulations, and show the characteristics of different manipulations and the movement details of finger joints.

ABSTRACT

OBJECTIVE@#To identify the key genes and explore mechanisms in the development of myelodysplastic syndrome (MDS) by bioinformatics analysis.@*METHODS@#Two cohorts profile datasets of MDS were downloaded from Gene Expression Omnibus (GEO) database. Differentially expressed gene (DEG) was screened by GEO2R, functional annotation of DEG was gained from GO database, gene ontology (GO) enrichment analysis was performed via Kyoto Encyclopedia of Genes and Genomes (KEGG) database, and key genes were screened by Matthews correlation coefficient (MCC) based on STRING database.@*RESULTS@#There were 112 DEGs identified, including 85 up-regulated genes and 27 down-regulated genes. GO enrichment analysis showed that biological processes were mainly enriched in immune response, etc, cellular component in cell membrane, etc, and molecular function in protein binding, etc. KEGG signaling pathway analysis showed that main gene enrichment pathways were primary immunodeficiency, hematopoietic cell lineage, B cell receptor signaling pathway, Hippo signaling pathway, and asthma. Three significant modules were screened by Cytoscape software MCODE plug-in, while 10 key node genes (CD19, CD79A, CD79B, EBF1, VPREB1, IRF4, BLNK, RAG1, POU2AF1, IRF8) in protein-protein interaction (PPI) network were screened based on STRING database.@*CONCLUSION@#These screened key genes and signaling pathways are helpful to better understand molecular mechanism of MDS, and provide theoretical basis for clinical targeted therapy.

ABSTRACT

OBJECTIVE@#To investigate the clinical significance and related factors of drainage tube after percutaneous endoscopic lumbar discectomy(PELD).@*METHODS@#The clinical data of 151 patients with lumbar disc herniation who underwent PELD from January 2019 to September 2019 was retrospectively analyzed. According to whether the drainage tube was used after operation, the patients were divided into drainage tube group and non drainage tube group. The placement time and total drainage volume were recorded. The characteristics of patients, such as age, gender, body mass index, lumbar disc herniation segment, smoking history, basic diseases and whether taking anticoagulants, were analyzed by single factor and multiple factor.@*RESULTS@#Drainage tubes were used in 32 patients after PELD. There were statistical differences in visual analogue scale(VAS) and Japanese Orthopaedic Assiciation(JOA) scores between postoperative and preoperative of that in two groups(P<0.05). There were statistical differences in VAS and JOA scores at discharge between two groups(P<0.05), while there were no statistical differences at other time points(P>0.05). Univariate analysis showed that age, basic diseases and whether taking anticoagulants were related to the use of drainage tube, but gender, body mass index, lumbar disc herniation segment and smoking history were not significantly related to the use of drainage tube. Multivariate analysis showed that elderly patients, complicated with hypertension and diabetes, taking anticoagulants were related to the use of drainage tube.@*CONCLUSION@#The use of drainage tube after percutaneous endoscopic lumbar discectomy can improve the symptoms of lumbar and leg pain in early stage. For elderly patients with hypertension, diabetes and taking anticoagulants drugs, drainage tube can be considered after transforaminal endoscopy.

ABSTRACT

Objective:To evaluate the safety and efficacy of conjoint fascial sheath (CFS) suspension surgery for severe blepharoptosis caused by low-tension suspension system.Methods:A total of 62 cases with severe blepharoptosis caused by low-tension suspension system received CFS suspension correction surgery from September 2014 to September 2017 were collected and followed up with a range of 12-36 months. The MRD-1, curve of upper eyelid, appearance and complications were recorded and underwent statistical analysis to evaluate the effect based on functionality, aesthetics and complication.Results:The postoperative MRD-1 was + 1 mm ~+ 4 mm compared with preoperative -3 mm ~+ 1 mm. The difference in the mean change was statistically different ( t=5.893, P<0.05). The satisfactory rate was 92.1% (82 cases), 7.9% (7 cases) were improved, and no case was invalid. There were no cases of recrudescence. Conclusions:Severe blepharoptosis can be caused by the inadequate tension of the upper eyelid suspension system. Laxity and abnormality of fixed structures may be major cause of decreasing levator aponeurotic tone. CFS suspension prevents further damage to the previous fixed structures, so it should be the first choice for such cases.

ABSTRACT

Objective @#To investigate the pathogenic factors and clinical manifestations of contact stomatitis, and to provide references for its clinical diagnosis and prevention. @*Methods@#The data of 55 subjects with contact stomatitis were analyzed retrospectively, including age, gender, pathogenic factors, type of lesions and site of occurrence.@*Results@#Among the 55 patients, contact stomatitis occurred at all ages, 19 were male, 36 were female, and the ratio of males to females was 1∶1.89. Among 55 patients, 78.18% (43/55) were caused by oral mucosal contact with dental materials: amalgam fillings accounted for 52.73% (29/55), metal crowns accounted for 9.09% (5/55), removable denture plastic bases accounted for 9.09% (5/55), resin fillings accounted for 5.45% (3/55), and alginate impression materials accounted for 1.82% (1/55); 21.82% (12/55) were caused by oral mucosal contact with food and daily necessities. The clinical manifestations of contact stomatitis include lichenoid reaction, erythema and erosion. The most common site of contact stomatitis was the cheek, followed by the tongue, and the lips, and the gingival and palatal areas were relatively rare. In the buccal mucosa, the incidence of lichenoid reaction was 55% (22/40), which was higher than that of erosion (20%) and erythema (25%), and the difference was statistically significant (P < 0.05). For tongue, lip, gingiva and palate, there was no significant difference in the incidence of the three lesion types(P > 0.05).@*Conclusion@#Contact stomatitis occurred at all ages, and there are more female patients than males with contact stomatitis. Dental materials, especially metal and acrylic materials (such as the plastic base of removable dentures, resin fillings, adhesives, and self-setting plastics), are the main pathogenic factors. In buccal mucosa, the incidence of lichenoid reaction is higher.

ABSTRACT

OBJECTIVE@#To explore the genetic basis for a fetus with renal abnormalities through whole exome sequencing and imaging examination.@*METHODS@#Clinical data and result of medical imaging of the fetus was collected. Amniotic fluid sample was collected for the extraction of fetal DNA. Whole exome sequencing was carried out. Candidate variants were verified by Sanger sequencing.@*RESULTS@#Prenatal ultrasonography showed that the fetus had bilateral enlargement of the kidneys with hyperechogenicity and diffuse renal cysts. Whole exome sequencing revealed that the fetus carried compound heterozygous variants of the PKHD1 gene, namely c.5137G>T and c.2335_2336delCA, which were derived from its mother and father, respectively.@*CONCLUSION@#The fetus was diagnosed with autosomal recessive polycystic kidney disease through combined prenatal ultrasonography and whole exome sequencing. The compound heterozygous variants of the PKHD1 gene probably underlay the pathogenesis in the fetus. The results have enabled prenatal diagnosis and genetic counseling for its parents.

ABSTRACT

The mixed teaching model combines the advantages of traditional teaching and network teaching in the “Internet +” era, which has become one of the important trends in the higher education teaching development. In order to follow this development trend, the human parasitology teaching team makes a reasonable use of modern information techniques, actively promotes the construction and application of online resources, and conducts mixed online and offline teaching based on MOOC resources and the experimental teaching digital platform. This mixed teaching model has shown a positive impact on both teaching and learning among teachers and students; however, students’ personalized independent and deep learning remains unsatisfactory. It is suggested that the online course resources construction, teaching design and digital literacy remain to be increased, so as to create a high-level, innovative and challenging online-offline mixed “golden course”

ABSTRACT

Objective@#To understand the situation of school health staff and the allocation of health equipment in primary and secondary schools in Jinan.@*Methods@#A questionnaire survey was conducted in CDC and public primary and secondary schools to describe the situation of the school health staff and health equipment in primary and secondary schools.@*Results@#There were 23 school health staffs in CDC, among which 26.1% were full time. The total staffing ratio of school doctors was 13.9%, with the compliance rate of 19.8%. The total allocation rate of health care teachers was 74.7%, 92.2% of them were part time. The total staffing ratio of school doctors in boarding schools was 20.0%, with a staffing compliance rate of 12.5%. The total allocation rate of school doctors and health care teachers in boarding schools was 66.7%. 16.8% of public primary and secondary schools and 23.3% of public boarding primary and secondary schools did not have any health staffs. 27.6% of public primary and secondary schools are equipped with infirmary, 70.8% with health rooms, and 10.3% without any. The configuration of necessary equipment in infirmary and health care rooms were less than 100%.@*Conclusion@#There is a serious shortage of school health staffs and health equipment in primary and secondary schools in Jinan. Attention and investment in school health should be strengthened, and resources should be rationally allocated to ensure the health of primary and secondary school students.
