Objective 　To evaluate the value of 99m　Tc-TRODAT-1 SPECT DAT imaging in the early diagnosing of Parkinsons disease (PD).Methods　 Eleven patients (9 PD and 2 possible PD) and eighteen healthy subjects matched by sex and age were studied with 99m　Tc-TRODAT-1 SPECT DAT imaging. Striatum specific uptake of 99mTc-TRODAT-1 was calculated according to the ratio of DAT uptake in striatum (ST) and cerebellum (CB). Results　In the hemi-Parkinsons disease group, the DAT specific uptake of 99mTc-TRODAT-1 was significantly lower (P＜0.01) in contralateral than in ipsilateral striatum to the clinically symptomatic side. There was significant decrease (p＜0.01) of striatum DAT uptake in patients with hemi-PD compared to the controls.Conclusions　99mTc-TRODAT-1 SPECT DAT imaging may help to confirm the diagnosis of PD at the early stage.

Objective To assess the clinical efficacy and safety of proton pump inhibitors (PPI)for preventing recurrence of non-steroidal anti-inflammatory drugs (NSAIDs)-indueed upper gastrointestinal ulcers using meta-analysis. Methods Mono- or multicenter randomized controlled clinical trials related to NSAIDs-indueed ulcers were retrieved from database of China Biological Medicine and Medline from 1966 to 2007. The data were analyzed by RevMan 4. 2 software using random or fixed effects model. Results Ten randomized controlled trials including 3361 patients were included, The recta-analysis revealed that PPI treatment significantly reduced the recurrent rate of NSAIDs-associated ulcers (8. 7%) in comparison with controls (17. 2%, P = 0. 03). Those who received esomeprazole (4. 4%) or lansoprazole (18. 0%) had a low recurrence of peptic ulcers compared with controls (14.7% or 28.7%, P value= 0.01 or 0.05). But there was no significant differencebetween omeprazole and controls (P= 0. 16). The recurrence of NSAIDs-associated ulcers in patients treated with esomeprazole 20 mg or 40 mg and tansoprazole 15 mg were 4.4%, 4.3% and 19.7 % respectively. The stratify analysis showed that PPI therapy could effectively reduce recurrentce of non-selective NSAIDs-induced ulcer (P= 0. 009), but failed to selective cyclooxygenase (COX)-2 inhibitor induced ulcer. No severe adverse reactions were found in PPI groups. Conclusion PPI is effective and safe in prevention of NSAIDs-related ulcers without discontinuation of NSAIDs.

Objective To screen for the miR-155 expression in synovial fibroblasts of rheumatoid arthritis (RASFs) and osteoarthritis (OASFs) and to evaluate the function of miR-155 on RASFs and its possible target mRNAs. Methods The expression levels of miR-155 in RASFs and OASFs were detected by real-time PCR. MiR-155 mimic and miR-155 inhibitor, as well as scrambled control were transfected into cultured RASFs by Lipofectamine 2000. Forty-eight hours later, MMP-3 levels in the cell culture supernatant were detected by ELISA and fibroblast proliferation was assayed by 3H -TdR incorporation test. Fibroblast invasive ability was tested by transwell system. IKBKE which previously identified as actual target of miR-155 was examined by real-time PCR. Comparisons between groups were performed with t test or one-way ANOVA analysis. Results It was shown that miR-155 was up-regulated in RASFs (1.79 ±1.94) and it was higher than that in OASFst (0.11±0.17), P<0.05]. Up-regulation of miR-155 could decrease MMP-3 levels (P<0.05). The proliferation and invasion of RASFs transfected with miR-155 were both evidently suppressed (P<0.05), while reducing the endogenous miR-155 could significantly enhance RASF proliferation (P<0.05). The expression of IKBKE of RASFs transfected with miR-155 was obviously down-regulated compared to those transfected with the scrambled control (P<0.05). Conclusion miR-155 is up-regulated in RASFs which may be a protective factor against the inflammatory effect, at least partially by attenuating the expression of IKBKK.

This paper was aimed to study medication laws of traditional Chinese medicine (TCM) towards rheumatoid arthritis (RA) based on modern medicine literatures. The China National Knowledge Infrastructure (CNKI), Wanfang Data knowledge service platform and VIP Database for Chinese Technical Periodicals were searched from January 2000 to December 2016 for relevant literatures on TCM for treatment of RA. The results showed that the database was established and the data were analyzed with statistics method including frequency analysis and cluster analysis. Finally, a total of 292 articles, 214 kinds of herbs were included, with a total frequency of 5071 for herbs. The results of frequency analysis, showed that tonic drugs, medicine for eliminating wind and dampness, drug for invigorating blood circulation and eliminating stasis were the main medications, followed by heat-cleaning drug, relieving external syndrome drug, and dampness-draining drug. The most common tastes of high frequency were sweet, pungent and bitter. The most common natures were warm and mild. The related meridians included the liver meridian, spleen meridian and kidney meridian. It was concluded that the cluster analysis showed medicines in the core group were as following: Astragalus, Licorice, Chinese angelica, Monkshood, Cassia twig, Coix seed, Radix saposhnikoviae, Radix gentianae macrophyllae, Notopterygium, Caulis spatholobi, Rhizoma ligustici wallichii, Twotooth achyranthes root, and Radix clematidis. The common combinations of RA drugs were summarized by association analysis. The medication law of RA treatment is to enrich consumptive disease and support healthy energy, to tonify the liver and kidney, to dispel wind and eliminate dampness, to remove blood stasis and dredge collaterals.

OBJECTIVETo investigate the association between children's and their parents' lifestyles, household environmental exposures and risk of childhood acute leukemia (AL).

METHODSA 1:2 matched case-control study of childhood AL was conducted in Shanghai between April 2011 and January 2014. The study enrolled 66 cases aged < 15, diagnosed with AL and 132 controls matched by age, gender and residence. All of the controls had no hematological diseases or previous history of malignancy. Children who had been adopted and had congenital genetic syndromes such as Down's syndrome or a positive HIV test result were not eligible as either cases or controls. Information was obtained from standardized face-to-face interviews of their parents/guardians with detailed questions on demographic characteristics, lifestyle, and household environment. Conditional logistic regression models were used to analyze effecting factors of childhood AL, odds ratios (OR) and their 95% confidence intervals (CI) were calculated.

RESULTSAmong 198 cases, 66 cases were aged (5.0 ± 3.7) years old, and 132 controls were aged (6.0 ± 3.8) years old (t = 0.48, P = 0.523). The paternal drink frequencies of cases and controls were 57.6% (38/66), and 31.1% (41/132), respectively (χ² = 4.91, P = 0.027). And the frequencies of household insecticides usage in the last year in the two groups were 78.8% (52/66), and 65.2% (86/132) (χ² = 3.87, P = 0.049). Chemical exposure during childhood (OR = 4.76, 95% CI: 1.34-16.89), maternal exposure to chemicals (OR = 4.51, 95% CI: 1.65-12.33), household insecticides use during 0-3 years of child (OR = 2.90, 95% CI: 1.31-6.39), and renovating after their children's birth (OR = 3.12, 95% CI: 1.26-7.74) were associated with an increased risk of childhood AL and these differences between the cases and the controls have statistical significance. Besides, we found that frequent contaction with other children during 0-3 years old (OR = 0.32, 95% CI: 0.15-0.69) and ventilation during sleeping in summer (OR = 0.43, 95% CI: 0.18-0.98) were associated with a decreased risk of childhood AL.

CONCLUSIONOur results support the association between children's and their parents' lifestyles, household environmental exposures and childhood AL.

Objective:In this study, the liver, spleen, and hepatic portal vein in the portal venous phase images of abdominal enhanced computed tomography (CT) are artificially segmented and annotated, and the radiomics features are extracted from them. A model for predicting portal pressure in patients with hepatitis B virus (HBV) related cirrhosis is constructed by combining radiomics features with clinical indicators.Methods:A total of 171 patients who had abdominal enhancement CT examination and trans-jugular hepatic venous pressure gradient (HVPG) measurement at the same time were enrolled from January 2016 to May 2020 in the Zhongshan Hospital Affiliated to Fudan University. The liver, spleen, and hepatic portal vein in the portal venous phase images of the CT were manually labeled by using ITK-SNAP 3.8 software. The radiomics features of these three sites were extracted using Python programming, and an HVPG prediction model was established.Results:A total of 171 patients was included in the study. The average age was (51.1±10.3)years, of which 134(78.4%) were males, and the average HVPG was 16.87±5.695. A total of 2 553 radiomics features were extracted from three sites of the portal venous phase images of abdominal enhanced CT in each patient. The 2 553 features extracted were screened using LASSO, and by combing with clinical features and radiomics features, the predictive model of HVPG was obtained: m_HVPG=31.622+ 0.028 8T×total bile acids-6.31(portal venous wavelet-LHH_glcm_ClusterShade)=0.253(portal venous wavelet-LHL_glszm_LargeAreaLowGrayLevelEmphasis)-20.9(spleen wavelet-LLH_glcm_Correlation)-0.000 127(liver original_shape_SurfaceArea)+ 2.79(liver wavelet-LLH_glcm_ClusterShade). The coefficient of determination R2 was 0.345. Conclusions:The study suggests that radiomics features of the liver, spleen, and portal venous combined with clinical features may be used as a non-invasive method to assess the portal pressure in patients with HBV-related cirrhosis.

Objective:To investigate the effect of hepatic venous pressure gradient (HVPG) on the prevention of rebleeding in cirrhotic patients of hepatitis B with gastroesophageal variceal hemorrhage receiving endoscopic therapy, and its influence on prognosis.Methods:Fifty eight patients with esophageal and gastric varices due to cirrhosis of hepatitis B admitted to Minhang Hospital Affiliated to Fudan University (from January 2019 to September 2021, n=18) and Zhongshan Hospital Affiliated to Fudan University (from January to September 2017, n=40) were retrospectively included. All of them underwent HVPG determination and endoscopic treatment. They were divided into HVPG≤18 mmHg group and HVPG>18 mmHg group. The rebleeding and survival status of these patients with endoscopic treatment was compared after a follow-up period of 2 years, and Cox regression was performed to analyze the related factors for rebleeding and survival. Results:A total of 58 individuals were included, which were divided into two groups: HVPG≤18 mmHg group (35) and HVPG>18 mmHg group (23). During the 2-year follow-up after the first endoscopic treatment, 13 patients (22.41%) developed rebleeding, including 4 patients in the HVPG≤18 mmHg group and 9 patients in the HVPG>18 mmHg group. The non-bleeding rate in HVPG≤18 mmHg group was significantly higher than that in HVPG>18 mmHg group (91.3% vs 68.7%, RR=3.54, 95% CI: 1.08-11.60, P=0.026), and the difference was statistically significant. Four patients died, including 1 patient in the HVPG≤18 mmHg group and 3 patients in the HVPG>18 mmHg group. There was no statistically significant difference in 2-year survival between the two groups (96.7% vs 86.5%, RR=4.44, 95% CI: 0.45-43.58, P=0.162). Cox regression multivariate analysis was used to analyze the above data, and the results suggested portal vein thrombosis ( HR=3.826, 95% CI: 1.263-11.585, P=0.018), HVPG>18 mmHg ( HR=4.243, 95% CI: 1.290-13.955, P=0.017) were independent risk factors for rebleeding in 2 years after endoscopic therapy. Conclusions:For patients with high HVPG, it should be fully evaluated and considered to receive other pressure lowering therapy, and treatment conversion should be carried out as soon as possible after endoscopic treatment failure.

ObjectiveTo explore the mechanism of Buyang Huanwutang in regulating macrophage polarization based on the Toll-like receptor 4 （TLR4） / nuclear factor-κB （NF-κB） / nucleotide-binding oligomerization domain-like receptor 3 （NLRP3） pathway. MethodRAW264.7 macrophages were intervened with lipopolysaccharide （LPS） of different concentrations （0， 1.25， 2.5， 5， 10， 20， 40， and 80 mg·L^-1） for 24 hours. Cell Counting Kit-8 （CCK-8） assay was used to determine the cell viability of RAW264.7 macrophages. The optimal concentration was chosen to establish an in vitro inflammation model induced by LPS. Cells were divided into a blank group （20% blank serum）， a model group （20% blank serum + 10 mg·L^-1 LPS）， a model control group （20% FBS + 10 mg·L^-1 LPS）， low-， medium-， and high-dose （5%， 10%， and 20%） Buyang Huanwutang-containing serum groups， a high-dose （20%） Buyang Huanwutang combined with NLRP3 inhibitor MCC950 （50 μmol·L^-1） group， a high-dose （20%） Buyang Huanwutang combined with reactive oxygen species （ROS） inhibitor NAC （10 μmol·L^-1） group， and a high-dose （20%） Buyang Huanwutang combined with NF-κB inhibitor PDTC （10 μmol·L^-1） group. Enzyme-linked immunosorbent assay （ELISA） was used to detect the expression of interleukin-1β （IL-1β）， interleukin-18 （IL-18）， and tumor necrosis factor-α （TNF-α） in RAW264.7 macrophages. Flow cytometry was employed to measure ROS levels in macrophages. Western blot was used to determine the protein expression of M1-type macrophage-related factors inducible nitric oxide synthase （iNOS） and TNF-α， M2-type macrophage-related factors arginase-1 （Arg-1） and interleukin-10 （IL-10）， as well as the proteins in the TLR4/NF-κB/NLRP3 pathway. ResultCCK-8 results indicated that under 10 mg·L^-1 LPS stimulation， RAW264.7 macrophages exhibited the highest cell viability （P<0.01）. Compared with the blank group， the model group showed significantly increased levels of IL-1β， IL-18， and TNF-α （P<0.05，P<0.01）， increased ROS expression （P<0.05，P<0.01）， increased protein expression of M1-type macrophage factors iNOS and TNF-α （P<0.01）， decreased protein expression of M2-type macrophage factors Arg-1 and IL-10 （P<0.05，P<0.01）， and upregulated expression levels of TLR4， myeloid differentiation factor 88 （MyD88）， phosphorylated inhibitor of NF-κB （p-IκB）/NF-κB inhibitor （IκB）， phosphorylated NF-κB （p-NF-κB） p65/NF-κB p65， NLRP3， apoptosis-associated speck-like protein containing a CARD （ASC）， and pro-Caspase-1 （P<0.05， P<0.01）. Compared with the model group， all Buyang Huanwutang-treated groups and inhibitor groups significantly reduced levels of IL-1β， IL-18， and TNF-α （P<0.01）， suppressed the expression of inflammatory factors in RAW264.7 macrophages， decreased cellular ROS expression levels （P<0.01）， downregulated M1-type macrophages iNOS and TNF-α protein expression （P<0.01）， upregulated M2-type macrophages Arg-1 and IL-10 protein expression （P<0.01）， and lowered protein expression levels of TLR4， MyD88， p-IκB/IκB， p-NF-κB p65/NF-κB p65， NLRP3， ASC， and pro-Caspase-1 （P<0.05， P<0.01）. ConclusionBuyang Huanwutang can improve macrophage inflammation， potentially by reducing macrophage ROS levels， inhibiting RAW264.7 macrophage polarization， and downregulating the protein expression levels of the TLR4/NF-κB/NLRP3 pathway.
