Objective To analyze the characteristics of viral hepatitis mortality and life loss among residents in Pudong New Area from 2003 to 2023, and to provide a basis for related prevention and control work. Methods Viral hepatitis mortality data were obtained from the Pudong New Area mortality monitoring system. The crude mortality rate (CMR), standardized mortality rate (SMR), potential years of life lost (PYLL), average years of life lost (AYLL), and standardized potential years of life lost (SPYLL) were calculated to analyze viral hepatitis deaths. The average annual change (AAPC) and annual percentage change (APC) of the mortality rate were calculated by Joinpoint regression analysis to analyze the trend of mortality. Results The CMR and SMR of viral hepatitis among residents in Pudong New Area from 2003 to 2023 were 3.89/100000 and 1.98/100000, respectively. Both CMR and SMR of viral hepatitis showed a decreasing trend over time (CMR:APC=-5.476, t=-13.581, P<0.001; SMR:APC=- 7.624, t= -21.253, P<0.001). The CMR for males was 4.75/100000 and the SMR for males was 2.65/100000; the CMR for females was 3.04/100000 and the SMR for females was 1.32/100000, with a higher mortality rate for males than for females（Z_CME=12.094，P<0.001; Z_SMR=-14.718，P<0.001). Deaths were concentrated in the age groups of 45-64 years old and 65 years old and above, accounting for 91.62% of the total deaths. The PYLL of deaths due to viral hepatitis among residents in Pudong New Area from 2003 to 2023 was 26912 person-years, with a PYLLR of 0.45% and an AYLL of 8.88 years per person. Conclusion The mortality rate of viral hepatitis among the residents of Pudong New Area in 2003-2023 shows a decreasing trend over time. The mortality rate of males is higher than that of females, and the deaths of middle-aged and elderly people account for a large proportion of the total deaths. Chronic hepatitis B is the main cause of death.

[Purpose]To analyze the trends in pancreatic cancer mortality and disease burden among residents in Shanghai Pudong New Area from 2002 to 2022,and to investigate the effects of age,period,and birth cohort on mortality risk.[Methods]Data on pancreatic cancer deaths among residents of Pudong New Area from 2002 to 2022 were collected through the Shanghai Population Cause of Death Registration System.The crude mortality rate,age-standardized mortality rate by Chinese standard population(ASMRC),potential years of life lost(PYLL),potential years of life lost rate(PYLLR),and average years of life lost(AYLL)were calculated.Joinpoint regression was applied to calculate the average annual percentage change(AAPC)for analyzing the changing trend of the mortality rate of pancreatic cancer.The age-period-cohort model was applied with R 4.4.1 to analyze the age,period,and cohort effects on the mortality risk of pancreatic cancer.[Results]The crude mortality rate of pancreatic cancer among residents in Pudong New Area increased from 10.42/105 in 2002 to 18.73/105 in 2022,showing a significant upward trend(AAPC=2.90％,P＜0.001);the ASMRC was generally stable(AAPC=-0.05％,P=0.775).The crude mortality rate of males(17.09/105)was higher than that of females(13.75/105),and both showed an upward trend(AAPC=3.05％and 2.75％respectively,both P＜0.001).After the age of 40,the mortality rate of pancreatic cancer increased significantly with the growth of age in both sexes.The PYLL was 31 347 person-years,showing an upward trend(AAPC=1.83％,P＜0.001),and the AYLL was 3.59 years,showing a downward trend(AAPC=-2.45％,P＜0.001).The age effect showed that the mortality risk of pan-creatic cancer was increased with age;the period effect showed that the mortality risk decreased from 2002 to 2016 and then increased;the cohort effect showed that the mortality risk increased with the advancement of the birth cohort.[Conclusion]From 2002 to 2022,the crude mortality rate of pancreatic cancer in Pudong New Area showed an upward trend,and the mortality rate of males was higher than that of females.The mortality risk of pancreatic cancer increases with age,and the later the birth year of the residents,the higher the mortality risk.Early screening should be strengthened for men and the elderly,environmental and lifestyle risk factors should be paid attention to in combination with the characteristics of cohort effect,and the prevention and control strategy for the whole population should be optimized.

Objective:To explore the possible mechanism of cognitive impairment in aged mice induced by sevoflurane and the role of the AMPK/GSK-3β/Nrf2 signaling pathway.Methods:Eighteen 16-month-old SPF male C57BL/6J mice were randomly assigned to either a control group or a sevoflurane group according to the random number table method( n=9 per group). Mice in the sevoflurane group were exposed to 3% sevoflurane for 2 h every day for three consecutive days.Cognitive function of mice was assessed by novel object recognition test and Morris water maze test.Golgi staining was used to analyze dendritic spine morphology and density in the hippocampus. Mitochondrial ultrastructure was examined by transmission electron microscopy. Oxidative stress in hippocampal tissue was evaluated by reactive oxygen species(ROS) and glutathione(GSH) assay kits. Western blot was performed to measure synaptic plasticity-related proteins and proteins involved in the AMPK/GSK-3β/Nrf2 signaling pathway, while Nrf2 expression was assessed by immunofluorescence. Statistical analysis was performed using GraphPad Prism 7 software with independent-samples t-test or Mann-Whitney U test for between-group comparisons. Results:(1) The novel object recognition test showed that the recognition index in the sevoflurane group was significantly lower than that in the control group ( Z=-3.256, P=0.001).The escape latency in the Morris water maze test was longer ((49.50±10.14) s, (18.62±6.59) s; t=-7.221, P<0.001) and the number of platform crossings was lower ( Z=-2.673, P=0.008) in the sevoflurane group compared with those of the control group. (2) Results from Western blot and Golgi staining showed that the expression levels of hippocampal synapse-related proteins in the sevoflurane group, including PSD95 ((0.38±0.07), (1.00±0.21); t=4.885) and SYN1 ((0.30±0.10), (1.00±0.10); t=8.575), were lower than those in the control group, as well as the number of dendritic spines ((10.3±2.5), (20.0±1.0); t=6.183)(all P<0.05). (3) Transmission electron microscopy showed mitochondrial damage in the hippocampus of the sevoflurane group, and the expression level of ROS ((3.05±0.90), (0.97±0.16); t=-4.555, P=0.004) was significantly higher than that of the control group, while the expression level of GSH ((0.71±0.07), (1.00±0.09); t=5.396, P=0.002) was significantly lower than that of the control group.(4) Western blot and immunofluorescence demonstrated that hippocampal p-AMPK, p-GSK-3β (Ser9), and HO-1 expression levels in the sevoflurane group were significantly lower than those in the control group ( t=2.845, 7.087, 4.551, all P<0.05), and Nrf2 fluorescence intensity was also markedly reduced ( P<0.05). Conclusion:The cognitive impairment induced by sevoflurane in aged mice may be caused by mitochondrial damage, oxidative stress response and synaptic damage, which maybe associated with the inhibition of the AMPK/GSK-3β/Nrf2 signaling pathway.

Attention-deficit/hyperactivity disorder(ADHD)is a common behavioral disorder in children and has significant non-specific symptoms.The specific pathogenesis of ADHD remains unclear.Chinese medicine has a unique advantage in treating this disease.The"qi cycle in round"theory is a unique diagnosis and treatment system constructed by Huang Yuanyu,a Qing Dynasty physician,through systematic integration and innovative development of the theoretical framework of traditional Chinese medicine,which is widely used in clinical practice.Based on the"qi cycle in round"theory,the pathogenesis of ADHD in children was discussed,and the abnormal middle qi was proposed as the root cause of the disease,with hyperactivity of the liver,lung depletion,and fire as the key contributing factors.Guided by the"qi cycle in round"theory in the treatment of ADHD in children,the approach focuses on restoring and balancing central qi.It emphasized the understanding of the overall changes in the spleen,stomach,lungs,liver,heart,kidney,and other viscera,along with the movement of qi.Treatment focuses on methods such as lifting clear yang,reducing stomach turbidity,softening the liver and quenching the wind,suppressing the lungs and reducing the inversion,and reducing the fire and returning to the yuan.These interventions aim to promote the smooth circulation of the qi circulation from multiple perspectives,thereby facilitating recovery.

Precancerous lesion of gastric carcinoma(PLGC)is a critical component of the occurrence,development,and metastasis of the"inflammation-cancer transformation".Traditional Chinese medicine(TCM)is characterized by a unique mode of diagnosis and treatment which adopts a holistic concept to differentiate and treat syndromes.With this mode,it can improve symptoms in patients,enhance the quality of their lives and elevate the histopathological performance.The pathogenic factors of PLGC are mostly related to spleen,among which the weakness of spleen and stomach is the pathogenetic basis of it.Over time,dampness,phlegm and blood stasis will accumulate in the body,causing local lesions.Spleen deficiency is associated with various development mechanisms of PLGC,including the gastric mucosal inflammation,intragastric flora,gastric mucosal barrier,immune function,energy metabolism,and gastric mucosal secretion.To treat PLGC from the perspective of the spleen theory,physicians should take steps to reinforce healthy Qi to eliminate pathogenic factors,give equal consideration to deficiency and excess,and harmonize the center to restore the balance in the viscera,which will invigorate the spleen and stomach,resolve dampness,clear heat and regulate qi and blood at the same time.The differentiation of the holistic and local syndromes should be combined and the treatment with drugs should take both diseases and syndromes into consideration.

Objective:To compare and discuss the mid-to-long-term outcomes of mitral valve repair (MVP) versus biological mitral valve replacement (bMVR) in patients aged 60 years and above with rheumatic mitral valve disease.Methods:This is a retrospective cohort study. A total of 765 patients aged 60 years and older, diagnosed with rheumatic mitral valve disease and who underwent MVP or bMVR at Beijing Anzhen Hospital from January 2010 to January 2023, were retrospectively included. Among them, 186 were male and 579 were female, with an age of (66.1±4.5) years (range: 60 to 82 years). Patients were divided into two groups based on the surgical method: the mitral valve repair group (MVP group, n=256) and the bioprosthetic mitral valve replacement group (bMVR group, n=509). A 1∶1 propensity score matching was performed using a caliper value of 0.2 based on preoperative data. Paired sample t-tests, χ2 tests, or Fisher′s exact tests were used for intergroup comparisons. Kaplan-Meier method was employed to plot survival curves and valve-related reoperation rate curves for both groups before and after matching, and Log-rank tests were used to compare the mid-to long-term survival rates and valve-related reoperation rates between the two groups. Results:A total of 765 patients who completed follow-up were ultimately included, with a follow-up period ( M(IQR)) of 5.1(5.0) years (range: 1.0 to 12.9 years). After matching, each group consisted of 256 patients. The incidence of early postoperative atrial fibrillation (39.1% vs. 49.2%, χ2=4.95, P=0.026) and early mortality rates (2.0% vs. 6.2%, χ2=4.97, P=0.026) were lower in the MVP group. Unadjusted Kaplan-Meier analysis showed significantly higher 5-year and 10-year survival rates for the MVP group (92.54% vs. 83.02%, 86.22% vs. 70.19%, Log-rank: P=0.001). After adjustment with propensity scores, the Kaplan-Meier analysis still indicated higher 5-year and 10-year survival rates in the MVP group compared to the bMVR group (92.54% vs. 85.89%, 86.22% vs. 74.83%, Log-rank: P=0.024). There were no significant differences in the rates of valve-related reoperation between the two groups before and after matching (5-year and 10-year reoperation rates pre-matching: 1.75% vs. 0.57%, 5.39% vs. 7.54%, Log-rank: P=0.207; post-matching: 1.75% vs. 0, 5.39% vs. 9.27%, Log-rank: P=0.157). Conclusion:For patients aged 60 years and above with rheumatic mitral valve disease, mitral valve repair offers better mid-to-long-term survival compared to biological valve replacement.

Objective:To analyze the clinical and laboratory characteristics of patients with cryoglobulinemia.Methods:It is a cross-sectional study. The patients diagnosed with cryoglobulinemia in our hospital were enrolled from July 2017 to March 2023. The baseline information of patients, included age, gender, qualitative, and quantitative results of serum cryoglobulins, initial clinical manifestations, etiology, serum complement 3 and 4, and the renal pathological manifestations. The clinical and laboratory characteristics of patients with different types of cryoglobulinemia were analyzed.Results:There were 62 patients (30.7%) with type Ⅰ cryoglobulinemia, 58 patients (28.7%) with type Ⅱ cryoglobulinemia, and 82 patients (40.6%) with type Ⅲ cryoglobulinemia enrolled in this study. Among these patients, 56 of primary cryoglobulinemia, 76 of autoimmune diseases, 29 of tumor-related diseases, and 52 of infectious diseases were observed. Clinical symptoms related to skin lesions (124 cases, 61.4%) and kidney damage (87 cases, 43.1%) were the most common initial clinical manifestations and arthralgia/arthritis (50 cases, 24.8%), peripheral neuropathy (33 cases, 16.3%), fatigue (28 cases, 13.9%), fever (23 cases, 11.4%) were also observed in some patients. The clinical symptoms varied in different types of cryoglobulinemia. 29.0% patients (18/62) with type Ⅰ had fatigue, which was higher than those with type Ⅱ (10.3%, 6/58) and type Ⅲ (4.9%, 4/82) ( P<0.05); Kidney damage occurred in 56.9% (33/58) patients with type Ⅱ and 52.4% (43/82) patients with type Ⅲ, which was higher than that in type Ⅰ patients (17.7%, 11/62) ( P<0.05); Only 4 patients (4.9%, 4/82) with type Ⅲ had peripheral neuropathy, which was lower than those with type Ⅰ (17.7%, 11/62) and type Ⅱ (31.0%, 18/58) ( P<0.05). The quantity of cryoglobulins in patients with type Ⅲ cryoglobulinemia [122 (82, 177) mg/L] was significantly lower than that in patients with type Ⅰ [695(229, 3 499) mg/L] ( P<0.001) and type Ⅱ cryoglobulinemia [350 (107, 1 874) mg/L] ( P<0.001). Complement 4 decreased in 49.0% (99/202) of patients and complement 3 decreased in 42.6% (86/202) of patients. Membranoproliferative glomerulonephritis (36.0%, 9/25) and endocapillary proliferative glomerulonephritis (32.0%, 8/25) were the main renal pathological manifestations of cryoglobulin nephropathy. Conclusions:The most common clinical manifestations of cryoglobulinemia are skin and kidney damage. The clinical manifestations of patients with cryoglobulinemia vary in different types of cryoglobulins. Serum complement decreases in nearly half of cryoglobulinemia patients.
