Objective:To investigate the current status of endoscopic treatment for gastroesophageal varices in portal hypertension in China, and to provide supporting data and reference for the development of endoscopic treatment.Methods:In this study, initiated by the Liver Health Consortium in China (CHESS), a questionnaire was designed and distributed online to investigate the basic condition of endoscopic treatment for gastroesophageal varices in portal hypertension in 2022 in China. Questions included annual number and indication of endoscopic procedures, adherence to guideline for preventing esophagogastric variceal bleeding (EGVB), management and timing of emergent EGVB, management of gastric and isolated varices, and improvement of endoscopic treatment. Proportions of hospitals concerning therapeutic choices to all participant hospitals were calculated. Guideline adherence between secondary and tertiary hospitals were compared by using Chi-square test.Results:A total of 836 hospitals from 31 provinces (anotomous regions and municipalities) participated in the survey. According to the survey, the control of acute EGVB (49.3%, 412/836) and the prevention of recurrent bleeding (38.3%, 320/836) were major indications of endoscopic treatment. For primary [non-selective β-blocker (NSBB) or endoscopic therapies] and secondary prophylaxis (NSBB and endoscopic therapies) of EGVB, adherence to domestic guideline was 72.5% (606/836) and 39.2% (328/836), respectively. There were significant differences in the adherence between secondary and tertiary hospitals in primary prophylaxis of EGVB [71.0% (495/697) VS 79.9% (111/139), χ2=4.11, P=0.033] and secondary prophylaxis of EGVB [41.6% (290/697) VS 27.3% (38/139), χ2=9.31, P=0.002]. A total of 78.2% (654/836) hospitals preferred endoscopic therapies treating acute EGVB, and endoscopic therapy was more likely to be the first choice for treating acute EGVB in tertiary hospitals (82.6%, 576/697) than secondary hospitals [56.1% (78/139), χ2=46.33, P<0.001]. The optimal timing was usually within 12 hours (48.5%, 317/654) and 12-24 hours (36.9%, 241/654) after the bleeding. Regarding the management of gastroesophageal varices type 2 and isolated gastric varices type 1, most hospitals used cyanoacrylate injection in combination with sclerotherapy [48.2% (403/836) and 29.9% (250/836), respectively], but substantial proportions of hospitals preferred clip-assisted therapies [12.4% (104/836) and 26.4% (221/836), respectively]. Improving the skills of endoscopic doctors (84.2%, 704/836), and enhancing the precision of pre-procedure evaluation and quality of multidisciplinary team (78.9%, 660/836) were considered urgent needs in the development of endoscopic treatment. Conclusion:A variety of endoscopic treatments for gastroesophageal varices in portal hypertension are implemented nationwide. Participant hospitals are active to perform emergent endoscopy for acute EGVB, but are inadequate in following recommendations regarding primary and secondary prophylaxis of EGVB. Moreover, the selection of endoscopic procedures for gastric varices differs greatly among hospitals.

ObjectiveTo investigate the therapeutic effect and mechanism of coptisine on chronic atrophic gastritis （CAG） in rats based on the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway. MethodA CAG rat model was induced by multiple factors， including sodium salicylate， N-methyl-N′-nitro-N-nitrosoguanidine （MNNG）， and irregular feeding. The successfully modeled rats were randomly divided into the model group， folic acid group， and high- and low-dose coptisine groups. The high- and low-dose coptisine groups were given coptisine （50， 10 mg·kg^-1， respectively）， and the folic acid group was given folic acid at 2 mg·kg^-1 for 60 days. The pathological changes were detected by hematoxylin-eosin （HE） staining. The ultrastructure of gastric mucosal cells was observed by electron microscopy. Serum pepsinogen Ⅰ （PGⅠ）， pepsinogen Ⅱ （PGⅡ）， and PGⅠ/PGⅡ ratio （PGR） were detected by immunoturbidimetry. Serum gastrin-17 （G-17） level was detected by radioimmunoassay. The content of interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β） in serum of rats was detected by enzyme-linked immunosorbent assay （ELSIA）. Western blot analysis was used to detect the expression levels of TGF-β₁， PI3K， phosphorylated-Akt （p-Akt）， mTOR， and phosphatase and tensin homolog deleted on chromosome 10 （PTEN） in gastric mucosa. The mRNA levels of TGF-β₁， PI3K， Akt， mTOR， PTEN， microtubule-associated protein light chain 3Ⅱ （LC3Ⅱ）， and Beclin-1 were detected by real-time quantitative polymerase chain reaction （Real-time PCR）. ResultCompared with the normal group， the model group showed atrophy and reduced number of intrinsic glands in the gastric mucosal tissues， as well as inflammatory cell infiltration. The ultrastructure of gastric mucosal cells in the model group displayed nuclear condensation， reduced and swollen mitochondria， and abnormal structure. The serum levels of G-17， PGⅠ， PGR， and the protein and mRNA levels of PTEN in gastric tissues were significantly lower in the model group （P<0.01）， while serum levels of IL-6， IL-1β， TNF-α， and the protein and mRNA levels of TGF-β₁， PI3K， Akt， and mTOR in gastric tissues were significantly higher （P<0.01）. Compared with the model group， various drug intervention groups showed different degrees of improvement in pathological damage and gastric mucosal cell ultrastructure， significantly increased serum levels of G-17， PGⅠ， and PGR （P<0.05，P<0.01）， and significantly decreased levels of IL-6， IL-1β， and TNF-α （P<0.05，P<0.01）. The high-dose coptisine group significantly downregulated the protein and mRNA levels of TGF-β₁， PI3K， Akt， and mTOR （P<0.05，P<0.01）. ConclusionBerberine has a therapeutic effect on CAG in rats， possibly exerting a protective effect on gastric mucosa by inhibiting inflammation and blocking the PI3K/Akt/mTOR signaling pathway.

BACKGROUND:Patients with degenerative cervical spondylosis often suffer from changed varicosity of the cervical spine,unbalanced neck-shoulder muscular strength,and descending power. OBJECTIVE:To probe into the correlation between sagittal curvature parameters and pain threshold for neck-shoulder muscles in degenerative cervical spondylosis. METHODS:Totally 50 patients with degenerative cervical spondylosis received treatment at the 3D Printed Outpatient Center of Shanghai Ninth People's Hospital,Shanghai Jiao Tong University School of Medicine from January 2022 to March 2023 were included in the study.After excluding the 10 patients of cervical lateral projection that failed to meet the measurement conditions,the cervical lateral projections were shot to measure the following iconography parameters:Borden value and C2-7 Cobb angle as well as pain thresholds on the midpoint of the superior trapezius muscle in bilateral bundles and at 1 cm beside the C5-6 interspike.The correlation between sagittal curvature parameters and pain threshold of neck-shoulder muscles in degenerative cervical spondylosis was analyzed. RESULTS AND CONCLUSION:(1)The Borden value of sagittal curvature showed a moderately positive correlation with the bundle pain threshold in the left upper trapezius muscle,the bundle pain threshold in the right upper trapezius muscle,and the pain threshold at the 1 cm of the left side beside the C5-6 interspike(r=0.498,P<0.01;r=0.448,P<0.05;r=0.405,P<0.05)and a weak positive correlation with the pain threshold at the 1 cm of the right side beside the C5-6 interspike(r=0.322,P<0.05).(2)The C2-7 Cobb angle showed a weak positive correlation with the left squared myalgia threshold(r=0.355,P<0.05),and there was no correlation with the pain threshold of the left trapezius muscle and the pain threshold at the 1 cm of both sides beside the C5-6 interspike.(3)There was a correlation between the pain threshold of the neck-shoulder muscles,and a high correlation between the pain threshold of the left and right muscles and the pain threshold within the left and right side muscles,indicating that the neck-shoulder muscles are consistent and may be related to the coordination of the neck-shoulder movements.

BACKGROUND:Short-term wearing of cervical brace combined with shoulder and neck muscle exercise can significantly improve the symptoms of early cervical spondylosis.After stopping wearing cervical brace,patients'symptoms are easy to recur,which may be due to the lack of cervical curvature correction function. OBJECTIVE:To analyze the effect of 3D printed personalized cervical orthopedic brace for adjusting cervical curvature in the treatment of early cervical spondylosis. METHODS:From January 2021 to January 2023,30 patients with early cervical spondylosis in the Shanghai Fifth People's Hospital,Fudan University were studied,including 11 males and 19 females,with a mean age of(31.7±6.6)years old.All patients customized and wore 3D printed personalized cervical orthopedic braces for 3 hours a day for continuous 12 weeks.Borden value of cervical curvature,pain threshold of shoulder and neck muscles,cervical dysfunction index,and visual analog scale score in 30 patients were recorded before and 4 and 8 weeks after treatment. RESULTS AND CONCLUSION:(1)Compared with before treatment,the difference of Borden value of cervical curvature,right trapezius tenderness threshold,and cervical dysfunction index was not significant in 30 patients after 4 weeks of treatment(P>0.05).Visual analog scale score,left trapezius tenderness threshold,left and right C5C6 tenderness threshold were significantly improved(P<0.05).(2)Compared with before treatment,the cervical curvature Borden value,left and right trapezius tenderness threshold,visual analog scale score,left and right C5C6 tenderness threshold,and cervical dysfunction index of 30 patients were significantly improved after 12 weeks of treatment(P<0.05).(3)Compared with 4 weeks after treatment,the Borden value of cervical curvature,right trapezius tenderness threshold,visual analog scale score,left and right C5C6 tenderness threshold and cervical dysfunction index of 30 patients after 12 weeks of treatment were significantly improved(P<0.05).(4)The results show that short-term wearing of 3D printed personalized cervical orthopedic brace can improve the pain of patients with early cervical spondylosis,while long-term application has certain effect on the recovery of cervical curvature.

BACKGROUND:Red light therapy has the non-invasive and cost-effective characteristics,and is widely used in various acute and chronic pains in clinic.However,currently,the phototherapy equipment used in clinic is expensive and has certain site limitations,so it is necessary to explore more convenient and economical phototherapy applications. OBJECTIVE:To observe the clinical efficacy of a self-developed photon cervical vertebra massage instrument for chronic neck pain. METHODS:From November 2022 to February 2023,24 patients with chronic neck pain were recruited from the Department of Rehabilitation Medicine,Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine,including 18 females and 6 males,with a mean age of(29.67±6.40)years.The body mass index was(21.39±3.52)kg/m2.Photon cervical vertebra massage instrument was used twice a day for 20 minutes each time for four weeks.The changes in visual analog scale score,pressure pain threshold,neck active activity,neck disability index,and Pittsburgh sleep quality index were observed before,after 2 and 4 weeks of treatment. RESULTS AND CONCLUSION:(1)Compared with before treatment,after four weeks of treatment,visual analog scale score,pressure pain threshold,neck disability index,and Pittsburgh sleep quality index were all improved(P<0.05),while some cervical motion(extension,left and right rotation)improved(P<0.05)after 4 weeks of treatment.(2)Bilateral visual analog scale scores,left trapezius muscle pressure pain threshold,C5C6 pressure pain threshold,and neck disability index improved after 2 weeks of treatment(P<0.05).(3)It is indicated that the application of photon cervical vertebra massage instrument can improve the pain score,muscle tenderness,sleep quality,functional level,and partial active activity of patients with chronic neck pain in a short period,and is a convenient,effective,and safe treatment method.

BACKGROUND:The study of the lumbar spine and pelvis in patients with Lenke type 5 lordosis is limited to the coronal and sagittal planes,and the three-dimensional relationship between the scoliosis and the pelvis has not yet been clarified. OBJECTIVE:To analyze the effect of lumbar scoliosis on the pelvis in patients with Lenke type 5 lordosis and to study the correlation between the lumbar spine and the three-dimensional spatial position of the pelvis. METHODS:Imaging data of 60 patients with Lenke type 5 lordosis scoliosis admitted to the 3D Printing Reception Center of Shanghai Ninth People's Hospital,Shanghai Jiao Tong University School of Medicine from January 2019 to September 2023 were retrospectively analyzed,including Cobb angle,coronal pelvic tilt,lumbar lordosis,left and right pelvic hip width ratio(sacroiliac-anterior superior iliac spine),spinal rotation angle,pelvic tilt,sacral slope,pelvic incidence,coronal deformity angular ratio,sagittal deformity angular ratio,C7 plumb line-center sacral vertical line,apical vertebral translation,and coronal sacral inclination.The information was summarized as a database.SPSS 22.0 software was used to analyze the data related to the lumbar spine and pelvis of the patients with Lenke type 5 primary lumbar curvature adolescent idiopathic scoliosis using Spearman's correlation analysis and linear regression. RESULTS AND CONCLUSION:(1)Cobb angle was highly positively correlated with coronal deformity angular ratio,apical vertebral translation,and spinal rotation angle(r=0.91,r=0.841,r=0.736).(2)Coronal deformity angular ratio was highly positively correlated with apical vertebral translation(r=0.737),moderately positively correlated with C7 plumb line-center sacral vertical line(r=0.514),and moderately negatively correlated with sagittal deformity angular ratio(r=-0.595).(3)There was a high positive correlation between lumbar lordosis and sagittal deformity angular ratio(r=0.942)and a moderate negative correlation with coronal deformity angular ratio(r=-0.554).(4)There was a moderate positive correlation between Cobb angle with coronal pelvic tilt and coronal sacral inclination(r=0.522,r=0.534)and a moderate positive correlation between C7 plumb line-center sacral vertical line and coronal pelvic tilt(r=0.507).Apical vertebral translation with coronal pelvic tilt and coronal sacral inclination showed a moderate positive correlation(r=0.507,r=0.506).Lumbar lordosis with sacral slope and pelvic incidence showed a moderate positive correlation(r=0.512,r=0.538).Sagittal deformity angular ratio was moderately positively correlated with sacral slope and pelvic incidence(r=0.614,r=0.621).(5)Studies have found that the relative position of the lumbar spine and the pelvis is closely related in the horizontal,sagittal and coronal planes.When the lumbar spine affects scoliosis and is rotated,the relative position of the pelvis will also change to compensate,which indicates that while correcting scoliosis,the correction of the pelvis cannot be ignored.

Objective:To explore the clinical features of fatty liver disease (FLD) from non-alcoholic fatty liver disease (NAFLD) to metabolic dysfunction-associated fatty liver disease (MASLD), so as to elucidate its clinical application value under three renames.Methods:Patients who were hospitalized in the Department of Hepatology, Hospital of Traditional Chinese Medicine Affiliated to Xinjiang Medical University, from January 2020 to September 2023 and met the diagnosis of NAFLD, metabolic-associated fatty liver disease (MAFLD), or MASLD were selected as the research subjects. The clinical indicators differences among the three groups of patients were compared, mainly including general information (age, gender, body mass index, past history, etc.), serological indicators (liver and kidney function, blood lipids, blood sugar, coagulation function, etc.), non-invasive liver fibrosis indicators, fat attenuation parameters, etc. Measurement data were analyzed using ANOVA and the rank sum test, while count data were analyzed using the χ2 test. Results:NAFLD, MAFLD, and MASLD prevalence rates among 536 cases were 64.0%, 93.7%, and 100%, respectively. 318 cases (59.3%) met the three fatty liver names at the same time among them. Male population proportions in NAFLD, MAFLD, and MASLD were 30.9%, 55.8%, and 53.9%, respectively. The alcohol consumption history proportion was 0, 36.7%, and 36.0%, respectively. The smoking history proportion was 7.0%, 31.9%, and 30.6%, respectively. The body mass index was (27.66 ± 3.97), (28.33 ± 3.63), and (27.90 ± 3.89) kg/m 2, respectively. The γ-glutamyltransferase levels were 26.6 (18.0, 47.0) U/L, 31.0 (20.0, 53.0) U/L, and 30.8 (19.8, 30.8) U/L, respectively. The high-density lipoprotein cholesterol levels were 1.07 (0.90, 1.23) mmol/L, 1.02 (0.86, 1.19) mmol/L, and 1.03 (0.87,1.21) mmol/L, respectively. Sequentially measured uric acid was (322.98 ± 84.51) μmol/L, (346.57 ± 89.49) μmol/L, and (344.89 ±89.67) μmol/L, respectively. Sequentially measured creatinine was 69.6 (62.9, 79.0) μmol/L, 73.0 (65.0, 83.5) μmol/L, and 73.0 (65.0, 83.0) μmol/L, respectively. The sequential analysis of obesity proportion was 74.3%, 81.7%, and 76.5%, respectively, with statistically significant differences ( P<0.05). Conclusion:Compared with the NAFLD population, the MAFLD and MASLD populations were predominantly male, obese, and had a history of smoking and drinking. The levels of γ-glutamyltransferase, uric acid, and creatinine were slightly higher, while the levels of high-density lipoprotein cholesterol were lower. MASLD appeared in NAFLD and MAFLD on the basis of inheritance and progression, emphasizing once again the important role of metabolic factors in a fatty liver.

Objective:To explore the influencing factors of clinical pregnancy outcomes in patients with hydrosalpinx undergoing in vitro fertilization-embryo transfer(IVF-ET) after interventional embolization and whether residual hydrops has an adverse impact on pregnancy outcomes.Methods:Clinical data from 65 patients who underwent interventional embolization and IVF-ET for hydrosalpinx at the Third Affiliated Hospital of Zhengzhou University from March 2021 to October 2022 were collected retrospectively. The hydrops index was quantified by the ratio of the widest diameter to the pelvic transverse diameter of the intraoperative hydrops, and the patient′s age, body mass index(BMI), follicle-stimulating hormone(FSH), lutenizing hormine(LH), estradiol(E2), automated matetials hangling(AMH), endometrial thickness at the time of transplantation, the number of transplanted embryos, embryo type, and location of the hydrosalpinx were recorded. In addition, the clinical pregnancy outcomes of the first transplantation after embolization were followed. Two independent samples t-test, rank sum test and chi-square test were used to analyze the difference of the above indexes among different clinical pregnancy outcomes by SPSS 25.0. The receiver operating characteristic (ROC) curves and Youden index were used to calculate the cut-off value of the water accumulation index. Results:Among 65 patients, the clinical pregnancy rate was 63.1%(41/65), among the 45 patients who underwent embryo transfer before embolization without success, the clinical pregnancy rate after embolization was 62.2%(28/45). Based on data analysis, it showed that IVF-ET clinical pregnancy outcomes were not associated with age, BMI, FSH, LH, E2, AMH, endometrial thickness at the time of transplantation, the number of transplanted embryos, embryo type, as well as location of hydrosalpinx( P>0.05), but associated with hydrosalpinx index( P<0.001). ROC curve analysis showed that the hydrops index could be used as a predictor of pregnancy outcome, and the area under the curve was 0.825, and the optimal cut-off value of the hydrops index was 12.925% based on the Youden index analysis result. Conclusions:Interventional embolization of hydrosalpinx may improve clinical pregnancy rates. When the hydrosalpinx is large enough, it could adversely affected IVF-ET clinical pregnancy, and further aspiration of hydrosalpinx should be performed prior to transplantation.

Objective:To investigate the ultrasonographic features and genetic etiology of complex talipes equinovarus (TE) in fetuses.Methods:This retrospective study enrolled 95 cases of complex TE (TE complicated by other abnormalities) who were diagnosed by prenatal ultrasound in the Third Affiliated Hospital of Zhengzhou University from March 2018 to December 2022. Chromosome karyotype analysis and/or chromosomal microarray analysis (CMA) [or copy number variation-sequencing (CNV-seq)] were performed on all cases for prenatal genetic diagnosis and those with normal results were further tested by whole exome sequencing (WES). Prenatal ultrasonographic and genetic features of complex TE in fetuses were summarized. Complicated abnormalities in the fetuses were classified into nine categories according to the involved system or site and based on each category these subjects were divided into with or without the corresponding complicated abnormalities groups. Besides, these cases were also divided into single-system and multi-system abnormality groups based on the number of involved systems or sites of complicated abnormalities. The detection rates of WES abnormality (pathogenic or likely pathogenic variants) and the overall detection rate of genetic abnormality [karyotype abnormality detected by chromosome karyotype analysis, pathogenic or likely pathogenic copy number variations (CNVs) detected by CMA (or CNV-seq), and pathogenic or likely pathogenic variation detected by WES] were compared between different groups using Chi-square test or Fisher's exact test. Results:Abnormal chromosome karyotypes were identified in 10 (24.4%) of 41 cases receiving chromosome karyotype analysis, pathogenic and likely pathogenic CNVs were found in seven (7.6%) of 92 cases by CMA (or CNV-seq). WES was performed on 37 cases with negative results of chromosomal karyotype analysis and CMA (or CNV-seq) and the detection rate of pathogenic and likely pathogenic variants was 43.2% (16/37). The detection rate of WES abnormality was higher in the fetuses with musculoskeletal abnormalities than in those without the abnormalities [71.4% (15/21) vs. 1/16, Fisher's exact test, P<0.001], while in those with other postural abnormalities was higher than that in the group without other postural abnormalities [12/16 vs. 19.0% (4/21), Fisher's exact test, P=0.001]. The genetic causes of complex TE were identified in 34.7% (33/95) of the fetuses by the sequential genetic diagnosis using chromosome karyotype analysis, CMA (or CNV-seq), and WES. The overall detection rate of genetic abnormality was higher in the group with multi-system abnormality than in the group with single-system abnormality [48.9% (22/45) vs. 22.0% (11/50), χ2=7.55, P=0.006], in the group with musculoskeletal system abnormalities and without [46.8% (22/47) vs. 22.9% (11/48), χ2=5.98, P=0.014], and in the group with other postural abnormality and without [47.2% (17/36) vs. 27.1% (16/59), χ2=3.99, P=0.046]. Nine cases that were considered isolated TE on initial ultrasound were corrected to a complex diagnosis on subsequent ultrasound examinations. Of all the involved system or site, the neurologic abnormalities were the most diverse (13 kinds) and had a diversity of ultrasound presentations. Conclusions:Genetic diagnosis should be performed when prenatal ultrasound suggests fetal complex TE. WES is conducive to improving the prenatal detection rate of monogenic diseases, especially in fetuses complicated by musculoskeletal abnormalities. Isolated TE fetuses require serial ultrasound examinations to correct the diagnosis in time and genetic testing should be performed if necessary. Additional attention should be paid to the TE fetus for comorbid neurologic abnormalities at the time of ultrasonography to rule out TE as an intrauterine harbinger of neuromuscular disease.
