Objective To study the correlation between isokinetic parameters and modified Ashworth Scale (MAS) in ankle spasticity as-sessment. Methods 18 stroke patients (spasticity group) and 16 healthy subjects (control group) in our hospitals from August 2014 to March 2015 were included. MAS was used to assess the ankle muscular tension. The ankle passive movement of both groups was measured with BIODEX isokinetic motor assessment system under 10 °/s, 60 °/s, 120 °/s, 180 °/s, 240 °/s. The peak torque (PT), peak torque/body weight (PT/BW), average torque (AT), and slopes of the linear regression curve of torque-velocity (SLOPE) were recorded. The correlation of the isokinetic paramenters and the MAS were tested with Spearman correlation analysis. Results The PT, PT/BW and AT were higher in the spasticity group than in the control group (P<0.05). And they increased as the angular velocity increased, and slowed after 120 °/s. The corre-lation coefficient of MAS and PT, PT/BW, AT, SLOPE were from 0.3043 to 0.7632 (P<0.01). Conclusion The isokinetic parameters were speed-dependent and closely related to MAS. 120 °/s was of the highest sensitivity, and the SLOPE under this anglular velocity was highly correlated with MAS.

Objective To find the plantar pressure readings which best indicate foot inversion during the stance phase of walking among hemiplegic stroke survivors.Methods Twenty-two hemiplegic stroke survivors who were able to walk without extra aid were recruited as the experimental group, while 17 healthy elderly men of similar age and body weight were selected as the control group.Those in both groups were asked to walk at their preferred speed over a Footscan device which measured medio-lateral pressure ratios, maximum plantar pressures and the contact areas of both feet.The Clinical Spasticity Index (CSI) was used to evaluate the affected feet.Results The average medial forefoot pressure of the affected side in the experimental group was significantly lower than that of the control group, but their average mesopodium and heel pressure was significantly higher.The average pressure applied by the great toe on the uninjured side in the experimental group was significantly smaller than that of the control group, but the average mesopodium and heel pressure of both feet among the hemiplegics were significantly higher than those of the control group.Among the experimental group, the average medial forefoot pressure of the affected foot was significantly greater than that of the healthy foot.The average contact area of the great toe on the affected side was significantly bigger than was observed in the control group.That of the medial forefoot was, however, significantly smaller than in the control group.There was no significant difference in the contact area between the healthy and affected feet in the experimental group, though the maxmium medio-lateral pressure ratios of their full feet and forefeet on the affected side were significantly lower than those in the healthy group.No significant differences in the maxmium medio-lateral pressure ratios of the heel were observed between the two groups, nor of the full feet, forefeet and heels of the affected and unaffected sides in the experimental group.The patients demonstrated consistently reduced joint mobility on both sides during the stance phase, coinciding with increased inversion.A significant negative correlation was found between the maxmium medio-lateral pressure ratios of the full foot and the maximum pressure of the lateral part of forefoot in the experimental group, but there was no significant correlation with contact area or CSI.Conclusions Plantar pressure data can be used to describe the amount of foot inversion in the stance phase of walking with hemiplegic patients after stroke.The maxmium medio-lateral pressure ratios can effectively reflect their foot inversion.

ObjectiveTo investigate the effect of the Yap1 gene and tanshinone ⅡA on the proliferation, migration, and invasion abilities of Huh-7 hepatoma cells. MethodsA total of 10 pairs of human hepatocellular carcinoma (HCC) samples and adjacent tissue samples were collected in Zhongnan Hospital of Wuhan University from June 1 to December 1, 2019. Quantitative real-time PCR and Western blotting were used to measure the expression of the Yap1 gene and phenotype-related molecules. MTT cell proliferation detection reagent was used to measure the inhibition rate of cell proliferation after the treatment with different concentrations of tanshinone ⅡA. Western blotting was used to measure the changes in the expression of apoptosis-and migration-related markers after different interventions. Flow cytometry and Transwell assay were used to measure apoptosis and cell migration and invasion abilities. The data of 375 cases of liver cancer and 50 cases of relatively normal liver tissue samples were downloaded from The Cancer Genome Atlas, including clinicopathological information. The t-test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. ResultsIn 8 of the 10 pairs of HCC samples and adjacent tissue samples, HCC samples had significantly higher expression of Yap1 than the adjacent tissue samples. Compared with the normal human liver epithelial cells L02, the Huh-7 and HCCL-M3 hepatoma cells had a significant increase in the expression of Yap1. The silencing efficiency of si-Yap1-3 transfection reached 87.004% at the protein level. MTT results showed that tanshinone ⅡA effectively inhibited the proliferation of Huh-7 cells, with a half inhibitory concentration of 8.683 μmol/L. After the cells were treated with si-Yap1-3 and tanshinone ⅡA, there was an increase in the expression of the downstream marker for proliferation and migration E-cadherin and a reduction in the expression of vimentin, and the results of Transwell assay showed that compared with the si-NC group, the tanshinone ⅡA+si-Yap1-3 group had significant reductions in the migration and invasion abilities of Huh-7 cells (migration: 43.19±2.88 vs 132.20±10.03, t=8.527, P=0.001; invasion: 53.95±4.20 vs 179.10±11.11, t=4.484, P=0.011). The group treated with si-Yap1-3 and tanshinone ⅡA had an increase in the expression of the apoptosis-related marker Bax and a reduction in the expression of Bcl-2, as well as a significantly higher early apoptosis rate than the si-NC group (2598% vs 9.21%, χ2=4.078, P＜0.05). ConclusionOncogene Yap1 silencing combined with tanshinone ⅡA can promote the apoptosis of Huh-7 hepatoma cells and inhibit their migration and invasion, which can provide certain guiding significance for clinical medication.

Objective:To explore the expression of the nucleotide-binding oligomerization domain-like receptor containing pyrin domain protein 6 (NLR family,pyrin domain containing 6,NLRP6) in the gastric tissue and gastric juice of children with chronic non-atrophic gastritis (CNG), and to analyze the influence of Helicobacter pylori (Hp) infection on the expression of NLRP6.Methods:A case-control study was conducted to select 120 CNG patients in pediatrics of Department of Pediatrics, The Affiliated Hospital of Xuzhou Medical University from October 2020 to July 2021. According to pathological diagnosis, endoscopic gastric mucosal damage and Hp infection, they were divided into 4 groups: mild CNG group Hp negative, Moderate to severe CNG group Hp negative, Mild CNG group Hp positive, Moderate to severe CNG group Hp positive. The enzyme-linked immunosorbent assay (ELISA) was used to detect the expression level of NLRP6 in the four groups of gastric tissue and gastric juice, and Western blot was used to detect the expression of NLRP6 in the gastric tissue of the 4 groups, and the significance of expression in CNG of children is analyzed. Independent sample t-test was used to compare the mean between the two groups. One way ANOVA was used to compare the mean of multiple groups of samples, and LSD t-test was used for pairwise comparison. Comparison between count data groups χ 2 inspection. Results:The positive rate of Hp in the moderate to severe chronic non-atrophic gastritis group was 62.96% (34/54) higher than that in the mild chronic non-atrophic gastritis group 37.04% (20/54), and the difference was statistically significant (χ 2=18.32, P<0.001). Under the same Hp conditions, the expression of NLRP6 in the mild chronic non-atrophic gastritis group (Hp negative mild CNG: gastric tissue (653.73±37.71) ng/L, gastric juice (471.75±38.47) ng/L; Hp positive mild CNG: Gastric tissue (616.69±43.33) ng/L, gastric juice (445.29±36.39) ng/L was higher than the moderate to severe chronic non-atrophic gastritis group (Hp negative moderate to severe CNG: gastric tissue (623.82±52.99) ng/L, gastric juice (446.48±47.49) ng/L; Hp positive Moderate to severe CNG: gastric tissue (580.43±62.75) ng/L, gastric juice (406.88±51.85) ng/L, the difference is statistically significant (under Hp negative, mild compared with moderate to severe CNG: gastric tissue P=0.035; gastric juice P=0.046; Under Hp positive, mild compared with moderate to severe CNG: gastric tissue P=0.010;gastric juice P=0.002); in the same degree of gastric mucosal injury, NLRP6 expression in Hp-negative group (Hp-negative mild CNG: gastric tissue (653.73±37.71) ng/L, gastric juice (471.75±38.47) ng/L; Hp negative moderate to severe CNG: gastric tissue (623.82±52.99) ng/L, gastric juice (446.48±47.49) ng/L higher than the positive group (Hp positive mild CNG: gastric tissue (616.69±43.33) ng/L, gastric juice (445.29±36.39) ng/L; Hp positive moderate to severe CNG: gastric tissue (580.43±62.75) ng/L, gastric juice (406.88±51.85) ng/L, the difference is statistically significant (under mild CNG, Hp negative is compared with positive: Gastric tissue P=0.005; gastric juice P=0.023; under moderate to severe CNG, negative versus positive: gastric tissue P=0.004; gastric juice P=0.003). Conclusion:Under the same Hp conditions, the more severe the gastric mucosal damage, the lower the NLRP6; under the same degree of mucosal damage, the expression level of NLRP6 in the Hp-negative group was significantly higher than that of the Hp-positive group. It is suggested that NLRP6 plays a role in inhibiting inflammation in chronic gastritis, maintaining the integrity of epithelial cells, and Hp can inhibit the expression of NLRP6.

Objective:To evaluate the long-term health-related quality of life (QOL) in pediatric patients with acute leukemia after hematopoietic stem cell transplantation (HSCT) and to analyze potential influence factors.Methods:Patients with acute leukemia aging 8-18 years who received HSCT in the Hematology Oncology Center of Beijing Children′s Hospital from June 2009 to June 2012 with more than 80 months survival postoperatively were recruited.All of them were subjected to a short-term QOL survey in 2013.PedsQL? Transplantation Module 3.0 in Chinese mandarin version was completed.QOL data and influence factors were analyzed.Results:Forty-one patients completed the questionnaires, involving 32 males and 9 females with the mean age of(14.29±2.72) years.The mean scores of overall long-term QOL after HSCT were above 75 (total scores: 100), which was above the average.The age, disease status before transplantation, donor sources, post-transplant complications and the parental education level were the influential factors for the long-term QOL in pediatric patients with acute leukemia at post-HSCT, which could affect a certain dimension in QOL.Conclusions:The overall long-term QOL of pediatric patients with acute leukemia who survived for more than 80 months at post-HSCT is acceptable, which is significantly better than the short-term QOL after 4 months of HSCT.The age, disease status before transplantation, donor sources, post-transplant complications and the education level of parents could affect a certain dimension of QOL.

Objective:Nuclear magnetic resonance spectroscopy (NMR) was used to detect the species and content of metabolites in urine of patients with inherited metabolic diseases, and to explore the application value of NMR technology in the diagnosis of inherited metabolic diseases.Methods:Urine samples were collected from 20 patients with inherited metabolic diseases diagnosed in Xinhua Hospital, Shanghai Jiaotong University School of Medicine from March to June 2019, including 9 cases of methylmalonic acidemia (MMA). NMR pulse length-based concentration determination and Gas chromatography mass spectrometry (GC/MS) semi-quantitative method were used to detect the composition of metabolites in urine samples of patients with inherited metabolic diseases, and the levels of abnormal metabolites in the two methods were analyzed.Results:NMR technology can detect the levels of characteristic metabolites significantly increased in the urine of patients with MMA, isovalerinemia, glutaric acidemia, propionic acidemia, 3-methylcrotonyl-CoA carboxylase deficiency, ornithine carbamyltransferase deficiency, Citrin deficiency, Canavan disease, tyrosinemia and lysinuria protein intolerance. The average is 8 times of the upper limit of the reference value, and the highest is 545 times. Compared to GC/MS, NMR technology can detect the levels of various metabolites such as organic acids, amino acids and sugars. In 9 cases of untreated MMA,the median levels of methylmalonic acid and 3-hydroxypropionic acid in NMR [1 800 (180-12 000) and 50 (0-270) mmol/mol Cr] were higher than the reference values (0-31, 0-35). The median levels of methylmalonic acid and methylmalonic acid in GC/MS [136.56 (43.79-518.67) and 4.87 (1.52-7.52)] were higher than the reference values (0-4 and 0-0.7).Conclusions:NMR and GC/MS technologies are specific for the diagnosis of organic acidemia. The primary component detected by GC/MS is organic acid. NMR technology can break through this limitation and measure the level of various metabolites in urine, which provides a more theoretical basis for the diagnosis and research of inherited metabolic disease.

OBJECTIVE To identify the chemical composition of Xiaoshi granules， and investigate its potential mechanism of action in the treatment of functional dyspepsia （FD）. METHODS Firstly， ultra-performance liquid chromatography tandem quadrupole time-of-flight mass spectrometry was used to analyze the composition of the Xiaoshi granules， and then network pharmacology was used to screen the potential targets of the Xiaoshi granules for the treatment of FD. Molecular docking of core components and targets was performed by using AutoDock Tools 1.5.6 software. RESULTS A total of 53 major chemical components， mainly flavonoids and organic acids， were identified from Xiaoshi granules. Network pharmacology screened core components such as quercetin， isorhamnetin， kaempferol and rutin， six core targets such as estrogen receptor （ESR1）， signal transducer and activator of transcription （STAT3）， androgen receptor（AR）， cellular tumor antigen （TP53）， hypoxia-inducible factor 1 subunit α in breast cancer tissue（HIF1A）， proto-oncogene tyrosine protein kinase （SRC）， and obtained major signaling pathways such as phosphatidylinositol 3-kinase （PI3K）-protein kinase B （Akt）， advanced glycosylation products （AGE）-receptor for advanced glycosylation end products （RAGE）， mitogen-activated protein kinase （MAPK）. The molecular docking results showed good docking activity between the core components and the core targets. CONCLUSIONS Xiaoshi granules may act on STAT3， HIF1A， SRC and other targets through quercetin， isorhamnetin， kaempferol and other active ingredients to regulate PI3K- Akt， AGE-RAGE， MAPK and other signal pathways， thus exerting its therapeutic effect on FD.

Objective:To analyze the disease spectrum of lysosomal storage disorders(LSDs) and explore the prevalent distributions of different LSD types in one center in Shanghai.Methods:A retrospective analysis was made.A total of 5 476 suspected LSD patients, including 3 415 males and 2 061 females, with a median age of 4 years(1 day to 72 years), were collected from Xinhua Hospital, Shanghai Jiaotong University School of Medicine from August 2008 to May 2022.The activity of different lysosomal enzymes was detected by fluorescent and biochemical methods.Results:A total of 1 520 patients were diagnosed with LSDs, including 972 males and 548 females, with a median age of 4 years(1 day to 59 years), involving 19 different subtypes.Mucopolysaccharidosis(MPS) was the most common type among LSDs, with a frequency of 45.46%(691/1 520), followed by sphingolipidoses [33.88%(515/1 520)] and glycogen storage disease type Ⅱ [16.05%(244/1 520)] successively.MPS Ⅱ was the most common type in MPS, with a frequency of 45.73%(316/691), followed by MPS ⅣA [22.87%(158/691)]. Niemann-Pick A/B, Gaucher, and Krabbe diseases were common in Sphingolipidoses patients, with frequencies of 37.09%(191/515), 34.37%(177/515), and 10.29%(53/515), respectively.Conclusions:LSDs are common genetic metabolic diseases, especially MPS and sphingolipidoses.Newborn screening for LSDs should be carried out timely so that the patients can be treated early and their prognosis can be improved.

Objective:To systematically evaluate the efficacy of different kinds of smoking cessation drugs by network Meta-analysis.Methods:Literature was retrieved from PubMed, Web of Science, Embase, Cochrane Library, CBM, CNKI, VIP, Wan fang database, from the establishment of the database to November 2022, and randomized controlled trials (RCT) about bupropion, varenicline, nicotine replacement therapy (NRT) versus placebo in the treatment of smoking patients were collected. After data extraction from included literature which met inclusion criteria, and quality evaluation with Cochrane 5.1 risk bias evaluation tool, network Meta-analysis was performed by Stata15.1 software.Results:A total of 19 RCTs, involving 6106 patients and three interventions measures (bupropion, varenicline, NRT) and one control measure (placebo) were included. The results of network Meta-analysis showed that in terms of short-term abstinence rate, varenicline [ OR=4.21, 95% CI (2.32, 7.63)], bupropion [ OR=2.81, 95% CI(1.05, 7.54)] were better than placebo ( P<0.05). The surface under the cumulative ranking area (SUCRA): varenicline (90.2%)>bupropion (64.8%)>NRT (41.7%)>placebo (3.2%). In terms of the long-term abstinence rate, varenicline [ OR=3.06, 95% CI (1.59, 5.90)], NRT [ OR=3.39, 95% CI (2.20, 5.21)] were better than placebo ( P<0.05). SUCRA: varenicline (83.8%)>NRT (73.9%)>bupropion (37.2%)>placebo (5.2%). Conclusion:The existing evidence shows that compared with bupropion, NRT, varenicline has the best effect on quitting smoking, but more high-quality randomized trial evidence is needed for verification.
