ObjectiveTo investigate the trends in diabetes mortality rate and the characteristics of decreased population in Fengxian District, Shanghai from 2012 to 2021. MethodsData from the death registration records of the residents in Fengxian District between 2012 and 2021, sourced from the Shanghai Death Surveillance System, were analyzed. Indicators such as the crude mortality rate due to diabetes, the standardized mortality rate, years of life lost (YLL), and the probability of premature death were estimated. Annual percentage change (APC) was used to analyze the temporal trends of mortality and the probability of premature death due to diabetes. Rate decomposition analysis was used to assess the contributions of demographic and non-demographic factors to diabetes mortality. ResultsFrom 2012 to 2021, there were 1 471 deaths due to diabetes in Fengxian District, with a crude mortality rate of 27.51/100 000 and a standardized mortality rate of 17.58/100 000. The crude mortality rate showed an overall increasing trend (APC=4.58%, Z=3.49, P<0.05). The potential years of life lost (PYLL) due to diabetes over this period amounted to 9 715 person-years, with a PYLL rate of 1.82 ‰, and the average years of life lost (AYLL) was 11.94 years. The probability of premature death was 0.41% (APC=3.36%, t=2.33, P<0.05). Both population aging and non-aging factors contributed to the increase in diabetes mortality, with overall contribution rates of 67.99% and 32.01%, respectively. Among men, the contribution rates were 60.57% and 39.43%, while among women, they were 79.43% and 20.57%, respectively. ConclusionFrom 2012 to 2021, both the crude mortality rate and the probability of premature death due to diabetes showed an upward trend among the residents in Fengxian District, with a higher YLL. Population aging was the main factor causing the increase in mortality rate, while non-demographic factors had a greater impact on the rise in diabetes mortality among men than that in women. Therefore, the management on male diabetes patients should be strengthened.

Objective:To investigate the diagnostic accuracy of serological indicators and evaluate the diagnostic value of a new established combined serological model on identifying the minimal hepatic encephalopathy (MHE) in patients with compensated cirrhosis.Methods:This prospective multicenter study enrolled 263 compensated cirrhotic patients from 23 hospitals in 15 provinces, autonomous regions and municipalities of China between October 2021 and August 2022. Clinical data and laboratory test results were collected, and the model for end-stage liver disease (MELD) score was calculated. Ammonia level was corrected to the upper limit of normal (AMM-ULN) by the baseline blood ammonia measurements/upper limit of the normal reference value. MHE was diagnosed by combined abnormal number connection test-A and abnormal digit symbol test as suggested by Guidelines on the management of hepatic encephalopathy in cirrhosis. The patients were randomly divided (7∶3) into training set ( n=185) and validation set ( n=78) based on caret package of R language. Logistic regression was used to establish a combined model of MHE diagnosis. The diagnostic performance was evaluated by the area under the curve (AUC) of receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve. The internal verification was carried out by the Bootstrap method ( n=200). AUC comparisons were achieved using the Delong test. Results:In the training set, prevalence of MHE was 37.8% (70/185). There were statistically significant differences in AMM-ULN, albumin, platelet, alkaline phosphatase, international normalized ratio, MELD score and education between non-MHE group and MHE group (all P<0.05). Multivariate Logistic regression analysis showed that AMM-ULN [odds ratio ( OR)=1.78, 95% confidence interval ( CI) 1.05-3.14, P=0.038] and MELD score ( OR=1.11, 95% CI 1.04-1.20, P=0.002) were independent risk factors for MHE, and the AUC for predicting MHE were 0.663, 0.625, respectively. Compared with the use of blood AMM-ULN and MELD score alone, the AUC of the combined model of AMM-ULN, MELD score and education exhibited better predictive performance in determining the presence of MHE was 0.755, the specificity and sensitivity was 85.2% and 55.7%, respectively. Hosmer-Lemeshow test and calibration curve showed that the model had good calibration ( P=0.733). The AUC for internal validation of the combined model for diagnosing MHE was 0.752. In the validation set, the AUC of the combined model for diagnosing MHE was 0.794, and Hosmer-Lemeshow test showed good calibration ( P=0.841). Conclusion:Use of the combined model including AMM-ULN, MELD score and education could improve the predictive efficiency of MHE among patients with compensated cirrhosis.

ObjectiveTo establish the characteristic sugar spectrum of polysaccharides， oligosaccharides and monosaccharides of wild-simulated and transplanted Astragali Radix， and find out the difference of the sugar spectrum between the two， so as to provide a basis for quality evaluation of Astragali Radix. MethodThe relative molecular weight distribution of polysaccharides from 18 batches of wild-simulated Astragali Radix and 12 batches of transplanted Astragali Radix were characterized by high performance liquid chromatography-evaporative light scattering detection（HPLC-ELSD） to establish the characteristic chromatograms of two kinds of polysaccharides. The difference in the peak area ratio of APS-Ⅱ， a polysaccharide component with a relative molecular weight of 10 kDa， in two kinds of Astragali Radix was analyzed， and the critical value of peak area ratio of APS-Ⅱ was determined by receiver operating characteristic（ROC） curve. At the same time， APS-Ⅱ was partially acid-hydrolyzed by trifluoroacetic acid（TFA） to establish characteristic spectra of two kinds of oligosaccharides from Astragali Radix based on HPLC-ELSD， and the characteristics of differential oligosaccharides were found by principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA）. Two kinds of APS-Ⅱ were completely acid-hydrolyzed by TFA and derivatized to establish characteristic spectra of two kinds of monosaccharides from Astragali Radix based on HPLC， PCA and OPLS-DA were performed on the peak area ratio of two kinds of monosaccharides to explore the differences in the composition of two kinds of APS-Ⅱ monosaccharides. ResultThe characteristic sugar spectrum of polysaccharides from Astragali Radix showed that the peak area ratio of APS-Ⅱ was the main difference， and the peak area of APS-Ⅱ of wild-simulated and transplanted Astragali Radix were 89.17%-97.17% and 80.14%-91.96%， respectively. The ROC curve determined the critical value of 92.28% for the difference of APS-Ⅱ peak area ratio of the two kinds of Astragali Radix. The multivariate analysis of APS-Ⅱ oligosaccharides revealed that the peak area ratio of oligosaccharides with polymerization degree≥10 was the main difference， which ranged from 11.835%-19.092% for wild-simulated products and 2.778%-7.017% for transplanted products. The results of monosaccharide characteristic sugar spectrum analysis showed that both Astragali Radix species consisted of six monosaccharides， and glucose and arabinose were the differential monosaccharide fractions. The peak area ratios of glucose and arabinose in wild-simulated products were 85%-93.9% and 2.7%-5.8%， respectively， while those of transplanted products were 74.3%-87.3% and 5.3%-10.7%， suggesting that the structures of the two polysaccharide fractions APS-Ⅱ of Astragali Radix may be different. ConclusionThe difference of sugar spectrum between two kinds of Astragali Radix may be related to the content and structure of APS-Ⅱ， and this study may provide a reference for the study of carbohydrates in Astragali Radix and the quality evaluation of medicinal materials.

Objective:To compare the prognoses of salvage liver transplantation fulfilling the Criteria of Milan, University of California San Francisco(UCSF)and Hangzhou.Methods:Clinical data were retrospectively reviewed for 256 patients with recurrent hepatocellular carcinoma(HCC)undergoing donation after citizen death(DCD)liver transplantation(LT)from January 2015 to October 2019.They were divided into two groups of primary(PLT, n=175)and salvage(SLT, n=81). General profiles, tumor pathological characteristics and postoperative complications of two groups were compared by T-test, rank-sum or χ2 test.Kaplan-Meier method and Log rank test were employed for comparing overall survival rate(OS)and recurrence-free survival rate(RFS)between two groups.In SLT group, 31 cases fulfilled Milan criteria, 45 cases UCSF criteria and 69 cases Hangzhou criteria.OS/RFS of three groups were compared.According to there was downstaging or bridging treatment pre-LT, SLT group was divided into downstaging group(n=32)and non-downstaging group(n=49). OS/RFS of two groups were compared.According to the Rescit1.1 criteria, downstaging group were divided into remission group(n=14)and non-remission group(n=18)and OS/RFS of two groups were compared. Results:The operative durations of PLT and SLT groups were(439.5±74.9)and(475.1±83.4)min respectively.There was significant inter-group difference( P<0.05); However, no significant inter-group difference existed in amount of intraoperative bleeding, blood transfusion, postoperative hospital stay or incidence of postoperative complications(all P>0.05). No significant difference existed in OS/RFS between PLT and SLT groups( P>0.05). No significant difference existed in OS at 1/3/5 years post-SLT among Milan, UCSF and Hangzhou criteria groups(all P>0.05); However, RFS in Milan criteria group at 1/3/5 years post-SLT were 93.5%, 81.7% and 81.7% respectively.They were significantly higher than 68.9%, 59.7% and 59.7% in UCSF criteria group and 78.3%, 58.8% and 55.5% in Hangzhou criteria group(all P<0.05). For patients on downstaging therapy, OS in the Remission group at 1, 3 and 5 years post-SLT were 100%, 73% and 73% respectively, which was significantly higher than 83.3%, 49.4% and 0 in non-Remission group( P=0.042). RFS in the Remission group at 1, 3 and 5 years post-SLT were 100%, 62.5% and 46.9% respectively, which was significantly higher than 52.9%, 0 and 0 in no-Remission group( P=0.001). Conclusions:The survival outcome of SLT recipients is similar to that of PLT recipients.The overall survival of SLT recipients shows no significant difference between Milan, UCSF and Hangzhou criteria.However, SLT recipients fulfilling Milan criteria have the longest recurrence-free time.The prognosis of patients with remission after preoperative descending treatment is superior to that of patients without remission.

BACKGROUND: The impact of sex on the clinical manifestations of rheumatoid arthritis (RA) were diversely reported in the literature. The Chinese Registry of rhEumatoiD arthrITis provides a platform for the investigation of this issue in Chinese patients. METHODS: Demographic and clinical parameters were collected from all enrolled patients with RA and from patients with early RA (disease duration ≤6 months). The differences in data regarding disease activity, comorbidities, and medications for RA were compared between men and women. The proportions of patients who achieved remission and low disease activity were compared at enrollment and during 3-, 6-, and 12-month follow-up visits. RESULTS: A total of 11,564 patients were enrolled, 83.6% of whom were female. In all the enrolled patients and patients with early RA, C-reactive protein (CRP, 12.0 vs . 6.7 mg/L), pain visual analogue scale (4.8 vs . 4.5), patient's and physician's global assessment (4.9 vs . 4.5 and 4.9 vs . 4.5), 28-joint disease activity score using DAS28-CRP (4.3 vs . 4.0) simplified disease activity index (21.9 vs . 19.9), and clinical disease activity index (19.3 vs . 18.0) were significantly higher in men than in women. Additionally, the swollen joint count/tender joint count and DAS28 using erythrocyte sedimentation rate were higher in male patients than in female patients with early RA. More female patients with early RA reached the treatment target at baseline than male patients (23.4% vs . 18.2%, assessed by CDAI). At 3 months, 6 months, and 12 months, the proportion of remission and treatment target achievement was similar in both sexes. Coronary artery disease (CAD) and stroke were more frequent in men than in women. CONCLUSIONS In Chinese patients with RA, men were found to have more active disease, as well as more cases of CAD and stroke. Therefore, sex should be carefully considered during the personalization of RA treatment.

Objective:To explore the application value of electromagnetic navigation technique in the removal of hematoma under neuroendoscope.Methods:Forty-three patients with supratentorial spontaneous cerebral hemorrhage, accepted removal of hematoma under neuroendoscope in our hospital from October 2015 to February 2019, were chosen in our study; 22 patients (navigation group) were performed the removal under the guide of real-time electromagnetic navigation, and 21 (non-navigation group) were performed the removal under neuroendoscope only. The amount of cerebral hemorrhage, operation time, residual amount of hematoma and hematoma clearance rate were compared between the two groups. Fugl-Meyer Assessment (FMA) was used to evaluate the motor function of the affected limbs two weeks after surgery. The anisotropy fraction (FA) values of fibers of affected pyramidal tracts and contralateral pyramidal tracts were examined by diffusion tensor imaging (DTI), and the relative FA (rFA) value (FA values of affected side/contralateral side) was calculated. Barthel index was used to evaluate the basic daily activities of the patients 6 months after surgery.Results:There was no significant difference between the navigation group and the non-navigation group in the amount of cerebral hemorrhage before surgery, amount of residual hematoma after surgery, hematoma clearance rate, and operation time ( P>0.05). FMA scores of upper and lower limbs, FA and rFA values of the affected side in the navigation group were significantly higher than those in the non-navigation group two weeks after surgery ( P<0.05). Barthel index of patients in the navigation group was statistically higher than that of the non-navigation group 6 months after surgery ( P<0.05). Conclusion:Electromagnetic navigation technique can guide endoscopy to effectively clear the supratentorial hypertensive cerebral hemorrhage without obviously increasing the operation time; effective protection of pyramidal fibers can improve the prognoses of patients.

Objective To compare the clinical efficacy of minimally invasive surgery and traditional surgery in the treatment of multiple benign mammary lumps.Methods A retrospective study was conducted to select 158 patients with multiple benign breast masses admitted to Yijishan Hospital of Wannan Medical College from July 2016 to February 2018,all of them were female,average age was (28.3 ± 6.6) years old,range from 19 to 51 years old.The patients were divided into minimally invasive group (n =122) and traditional group (n =36) according to different surgical methods.The minimally invasive group was treated by minimally invasive rotary excision,while the traditional group was treated by traditional surgery.The operation time,number of incisions,average length of incisions,cumulative length of incisions and healing time of incisions were compared between the two groups.The incidence of local hematoma,local infection,breast deformity and local residual were compared after operation,and the satisfaction of the two groups was aslo compared.Normal distribution measurements were expressed by mean ± standard deviation (Mean ± SD),independent sample t test was used for inter-group comparison;non-normal distribution measurements were expressed by median (quartile spacing) [M(P25,P75)],Mann-Whitney U test was used for inter-group comparison.Chi-square test or Fisher exact probability test was used to compare the count data between the two groups.Results As compared to the traditional group,the minimally invasive group had shorter operation time (20.0 min vs 40.0 min,Z =-8.590,P ＜ 0.001),less number of incisions (1.0 vs 2.0,Z =-4.423,P ＜0.001),smaller average surgical incision length (3.8 mm vs 35.5 mm,Z =-9.211,P ＜ 0.001),smaller cumulative surgical incision length (4.0 mm vs 67.2 mm,Z =-9.130,P ＜ 0.001),quicker postoperative recovery (4.0 d vs 7.0 d,Z =-9.334,P ＜ 0.001).There were no significant differences between the two groups in incidence of postoperative hematoma (4.1％ vs 2.8％,x2 =0.000,P =1.000),incidence of infection (0 vs 2.8％,P =0.228),incidence of postoperative breast shape change (1.6％ vs 2.8％,x2 =0.000,P =1.000),and incidence of residual (0.8％ vs 0,P =1.000).Psychological satisfaction of patients in minimally invasive group (95.1％) was significantly higher than that in traditional group (58.3％),the difference was statistically significant (P ＜ 0.001).Conclusions Compared with traditional surgery,the application of minimally invasive surgery in the treatment of multiple benign mammary lumps has many advantages,such as shorter operation time,less number of incisions,smaller surgical incision length,quicker postoperative recovery and higher satisfaction of patients after operation.It has not significantly increased postoperative complications.It is worthy of clinical application and promotion.

Objective: To explore the risk factors of predicting white matter hyperintensities progression based on radiomics of MRI of whole-brain white matter. Methods: The imaging and clinical data of 152 patients with white matter hyperintensities admitted to Zhejiang People′s Hospital from March 2014 to October 2018 were retrospectively analyzed. The whole brain white matter on baseline T₁WI images of each patient were segmented by SPM12 software package, and images of white matter were imported into AK software for texture feature extraction and dimensionality reduction. At last, least absolute shrinkage and selection operator(LASSO) was used to calculate the score of radiomics signature of each patient. According to the improved Fazekas scale, patients with WMH progression were divided into three groups: any white matter hyperintensities (AWMH), periventricular white matter hyperintensities (PWMH) and deep white matter hyperintensities (DWMH). Statistical differences of clinical factors and radiomics signature between WMH progression subgroups and non-progression subgroups were compared with independent sample t test or Mann-Whitney U test, and Univariate logistic regression was used to select independent clinical risk factors and multivariate logistic regression along with imaging omics tags were used to construct predictive models, which was evaluated by ROC curve. And the correlation between the clinical indicators of independent risk factors and the texture feature of radiomics signature was analyzed. Results: The efficacy of the model for the detection for AWMH progression, PWMH progression and DWMH progression was 0.818,0.778 and 0.824, respectively. Age is an independent risk factor for AWMH progression and DWMH progression[OR(95%CI), 4.776(2.152-10.601) vs. 3.851(1.101-8.245); P<0.05]. BMI is an independent risk factor for DWMH[OR(95%CI), 3.004(1.204-7.370); P<0.05], and hyperlipidemia is an independent risk factor for AWMH and PWMH[OR(95%CI), 4.062(1.834-8.998) vs. 3.549(1.666-7.563); P<0.05]. In AWMH subgroup, Surface Area was negatively correlated with age and low density lipoprotein(LDL) (r=-0.401, -0.312), and Inverse Difference Moment_ALLDirection_offset 1_SD was negatively correlated with age(r=-0.412). In PWMH subgroup, Compactness 1 was negatively correlated with LDL(r=-0.198), and Inverse Difference Moment_angle 0_offset 7 was positively correlated with LDL(r=0.252). In DWMH subgroup, LongRunEmphasis_ALLDirection_offset 7 was negatively correlated with age(r=-0.322), and GLCMEntropy_angle0_offset 4 was negatively correlated with age(r=-0.278). GLCMEntropy_AllDirection_offset4 was negatively correlated with body mass index(r=-0.514). Conclusion Radiomics based on whole-brain white matter MR imaging can predict WMH progression and identify the risk factors in high-risk populations, thus providing early additional information to conventional magnetic resonance imaging to predict WMH progression.
