ObjectiveTo investigate the prevalence of gynecological and breast diseases among retired or economically disadvantaged women in part of Pudong New Area of Shanghai under the policy support of screening gynecological diseases and breast diseases for retired and women with economic difficulties in life in Shanghai, to analyze the characteristics of these diseases, so as to provide a scientific basis for the improvement of relevant prevention and treatment strategies. MethodsBased on the gynecological census data of 13 031 cases in five towns, including Xinchang Town, Xuanqiao Town, Laogang Town, Wanxiang Town and Shuyuan Town, conducted by Shanghai Pudong Hospital in 2023, descriptive analysis methods were used to explore the prevalence and age characteristics of common gynecological and breast diseases. ResultsThe total detection rate of gynecological and breast diseases among women in the screening area in this study was 68.29%, with uterine fibroid (22.35%), sarcoidosis of the breast (17.06%), cervicitis (15.37%), vaginitis (8.39%) and ovarian cyst (2.61%) ranking the top 5 in the detection rate among the screening population. The differences of the detection rates in the four major diseases [uterine fibroid (χ²=233.217, P<0.001), breast nodules(χ²=169.896, P<0.001), cervicitis (χ²=388.683, P<0.001), and ovarian cysts (χ²=72.298, P<0.001)] by different age groups were statistically significant (P<0.05) . Moreover, the results of pairwise comparison of different age groups showed that the detection rates in the age group under 45 years old and 45‒55 years old were higher than that in the age group of 55‒65 years old and over 65 years old. ConclusionThe detection rate of gynecological and breast diseases in the younger age group was higher, indicating a certain trend of younger onset of diseases. Uterine fibroid, sarcoidosis of the breast , and reproductive tract diseases such as cervicitis, vaginitis, and ovarian cyst are the main diseases affecting the research subjects. Therefore, medical institutions can combine routine work in screening diseases and carry out corresponding health education and health promotion activities for these key diseases to improve women’s health.

OBJECTIVES: To explore the therapeutic effect of LuoFuShan Rheumatism Plaster (LFS) on neuropathic pain (NP) and its molecular mechanism. METHODS: Mouse models of sciatic nerve chronic constriction injury (CCI) were treated with low, medium, and high doses (2.2, 4.4, and 8.8 cm², respectively) of LFS by topical application for 14 consecutive days. The therapeutic effects were assessed by evaluating the mechanical withdrawal threshold (MWT), paw withdrawal latency (PWL), plasma IL-6 and TNF-α levels, and histopathology of the sciatic nerve. Network pharmacology and molecular docking were used to identify the key targets and signaling pathways. The key targets were verified by RT-qPCR and immunohistochemistry. The biosafety of LFS was evaluated by measuring the organ indices and damage indicators of the heart, liver, and kidneys. RESULTS: Compared with the CCI group, LFS dose-dependently increased MWT and PWL, reduced plasma IL-6 and TNF-α levels, and alleviated sciatic nerve inflammation in the mouse models. Network pharmacology identified 378 bioactive compounds targeting 279 NP-associated genes enriched in TLR and TNF signaling. Molecular docking showed that quercetin and ursolic acid in LFS could stably bind to TLR4 and TNF‑α. In the mouse models of sciatic nerve CCI, LFS significantly downregulated the mRNA expression levels of Tlr4 and Tnf-α in the spinal cord in a dose-dependent manner and lowered the protein expressions of TLR4 and TNF-α in the sciatic nerve. LFS treatment did not cause significant changes in the organ indices or damage indicators of the heart, liver and kidneys as compared with those in the CCI model group and sham-operated group. CONCLUSIONS LFS alleviates NP in mice by suppression of TLR4/TNF-α-mediated neuroinflammation with a good safety profile.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.

Objective:To evaluate the efficacy and safety of Hymagic-4D multi-essence (miniHA, acetylated sodium hyaluronate, sodium hyaluronate, sodium hyaluronate cross-linked polymer) on sensitive skin.Methods:The clinical trial was conducted from April 2, 2019 to April 30, 2019 in the Cosmetic Dermatology Laboratory of the Third Affiliated Hospital of Sun Yat-Sen University. A total of 33 subjects (average age of 43±9.5) completed the trial. Subjects diagnosed as sensitive skin according to the criteria were enrolled. Hymagic-4D were randomly applied on one side of the face while macromolecular hyaluronic acid was applied on opposite side for 28 days. Skin biophysical properties, lactic test, clinical efficacy and safety were evaluated by the investigators at day 0, day 7, day 14 and day 28. Skin water content, TEWL and a*value were measured at the same time.Results:Dates showed that at day 7, day 14 and day 28, the a* values on Hymagy-4D using side were 8.54±3.08, 8.87 ±3.21 and 8.39±3.21, lower than that on the side of control 9.48±3.09, 9.51±3.30 and 9.03±2.95 ( P<0.01); skin roughness score, dryness score and erythema score on hymagy-4d using side were significantly lower than before ( P<0.01), and significantly lower than that on the control side ( P<0.01). Hydration, TEWL, pH value, L value and total score of lactic acid tingling test which were significantly improved on both facial skin compared to the baseline ( P<0.05) showed no statistical difference between two facial sides ( P>0.05) during 28-day treatment. Conclusions:This study demonstrates that Hymagic-4D has more effective in repairing skin barrier and inhibiting skin inflammation than single component hyaluronic acid on sensitive skin persons.

Objective To compare the image quality produced by MR high resolution vessel wall imaging (HR?VWI) and ultrasound (US) in evaluating carotid plaque load. Methods This prospective study enrolled 21 patients with carotid plaques undergoing HR?VWI and subsequent 2D US between August 2016 to January 2017 in Hebei General Hospitial. The plaque thickness (PT), lumen area (LA), wall area (WA) and total vessel area (TVA) of the plaques were measured and normalized wall index (NWI) was calculated on both HR?VWI images and US for those plaques with image quality score≥3 and matching between the two methods. The plaque load index was compared by using the independent sample t test or the non?parametric Wilcoxon test, and the correlation between the indexes was based on the Pearson test. Results Forty?five carotid plaques were matched with HR?VWI and US. There was no significant difference in PT, LA, WA, TVA and NWI detected by HR?VWI and ultrasound (P>0.05). The parameters measured by two methods were correlated (r values were 0.83, 0.85, 0.32, 0.83 and 0.59, P<0.05). Conclusion There is a good consistency between HR?VWI and conventional ultrasound in the measurement of carotid plaque load.

Objective To evaluate the effect of oxycodone pretreatment on autophagy during renal ischemia-reperfusion (I/R) in rats.Methods Thirty-six SPF healthy adult male Wistar rats,aged 6-9 weeks,weighing 180-220 g,were divided into 3 groups (n=12 each) using a random number table:sham operation group (Sham group),I/R group and oxycodone pretreatment group (Oxy group).The left renal pedicles were clamped with atraumatic microclips for 45 min followed by reperfusion to establish the model of renal I/R injury in I/R and Oxy groups.Oxycodone 0.5 mg/kg was injected via the caudal vein at 15 min before ischemia in group Oxy,and the equal volume of normal saline was given instead in I/R and Sham groups.At 24 h of reperfusion,blood samples were collected from hearts for measurement of serum creatinine (Cr) and blood urea nitrogen (BUN) concentrations.The animals were then sacrificed and left renal tissues were obtained for examination of pathological changes (with a light microscope) and for determination of Bcl-2 and Beclin-1 expression (by immunohistochemistry).Results Compared with Sham group,the concentrations of serum Cr and BUN were significantly increased,and the expression of Bcl-2 and Beclin-1 in renal tissues was up-regulated at 24 h of reperfusion in I/R and Oxy groups (P<0.05).Compared with I/R group,the concentrations of serum Cr and BUN were significantly decreased,the expression of Bcl-2 in renal tissues was up-regulated,and the expression of Beclin-1 in renal tissues was down-regulated at 24 h of reperfusion (P<0.05),and the pathological changes were significantly attenuated in Oxy group.Conclusion Oxycodone pretreatment inhibits autophagy through up-regulating the expression of Bcl-2 and down-regulating the expression of Beclin-1,thus attenuating renal I/R injury in rats.

Objective To compare the effects of oxycodone and morphine on myocardial ischemiareperfusion (I/R) injury in rats.Methods Forty-eight SPF healthy adult male Sprague-Dawley rats,aged 8-10 weeks,weighing 250-300 g,were randomized into 4 groups (n =12 each) using a random number table:sham operation group (S group),myocardial I/R injury group (I/R group),morphine group (M group) and oxycodone group (O group).Myocardial I/R was produced by occlusion of the anterior descending branch of the left coronary artery for 30 min followed by 120 min of reperfusion.In group S,the anterior descending branch of the left coronary artery was only exposed but not ligated.In M and O groups,morphine 1.5 mg/kg and oxvcodone 0.5 mg/kg were injected,respectively,via the internal jugular vein at 5 min before ischemia.At the end of reperfusion,arterial blood samples were collected via cardiac puncture for determination of the serum creatine kinase-MB (CK-MB) and cardiac troponin Ⅰ (cTnI) concentrations.Myocardial infarct size was measured by 2,3,5-triphenyhetrazolium chloride staining.Apoptosis in cardiomyocytes was determined by TUNEL,and apoptosis index (AI) was calculated.Results Compared with S group,serum CK-MB and cTnI concentrations and AI were significantly increased,and myocardial infarct size was enlarged in I/R,M and O groups (P＜0.05).Compared with I/R group,serum CK-MB and cTnI concentrations and AI were significantly decreased,and myocardial infarct size was decreased in M and O groups (P＜0.05).Serum CK-MB and eTnI concentrations and AI were significantly lower,and myocardial infarct size was smaller in O group than in M group (P＜0.05).Conclusion Oxycodone produces better efficacy than morphine in reducing myocardial I/R injury in rats.
