BACKGROUND: Spicy food consumption has been reported to be inversely associated with mortality from multiple diseases. However, the effect of spicy food intake on the incidence of vascular diseases in the Chinese population remains unclear. This study was conducted to explore this association. METHODS: This study was performed using the large-scale China Kadoorie Biobank (CKB) prospective cohort of 486,335 participants. The primary outcomes were vascular disease, ischemic heart disease (IHD), major coronary events (MCEs), cerebrovascular disease, stroke, and non-stroke cerebrovascular disease. A Cox proportional hazards regression model was used to assess the association between spicy food consumption and incident vascular diseases. Subgroup analysis was also performed to evaluate the heterogeneity of the association between spicy food consumption and the risk of vascular disease stratified by several basic characteristics. In addition, the joint effects of spicy food consumption and the healthy lifestyle score on the risk of vascular disease were also evaluated, and sensitivity analyses were performed to assess the reliability of the association results. RESULTS: During a median follow-up time of 12.1 years, a total of 136,125 patients with vascular disease, 46,689 patients with IHD, 10,097 patients with MCEs, 80,114 patients with cerebrovascular disease, 56,726 patients with stroke, and 40,098 patients with non-stroke cerebrovascular disease were identified. Participants who consumed spicy food 1-2 days/week (hazard ratio [HR] = 0.95, 95% confidence interval [95% CI] = [0.93, 0.97], P <0.001), 3-5 days/week (HR = 0.96, 95% CI = [0.94, 0.99], P = 0.003), and 6-7 days/week (HR = 0.97, 95% CI = [0.95, 0.99], P = 0.002) had a significantly lower risk of vascular disease than those who consumed spicy food less than once a week ( Ptrend <0.001), especially in those who were younger and living in rural areas. Notably, the disease-based subgroup analysis indicated that the inverse associations remained in IHD ( Ptrend = 0.011) and MCEs ( Ptrend = 0.002) risk. Intriguingly, there was an interaction effect between spicy food consumption and the healthy lifestyle score on the risk of IHD ( Pinteraction = 0.037). CONCLUSIONS Our findings support an inverse association between spicy food consumption and vascular disease in the Chinese population, which may provide additional dietary guidance for the prevention of vascular diseases.

Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

Objective To evaluate the effectiveness of phacoemulsification with intraocular lens(IOL)implantation combined with a capsular tension ring in patients with high myopia and cataract.Methods A total of 76 patients with high myopia and cataract who were admitted to the Xi'an Fengcheng Hospital from February 2019 to May 2022 were assigned to control group(n=38)and study group(n=38)by random number table.The control group underwent phacoemulsification with IOL implantation,and the study group received additional treatment with a capsular tension ring on the basis of the control group.The best corrected visual acuity(BCVA),intraocular pressure(IOP),anterior chamber depth(ACD),effective lens position(ELP),subjective visual quality,and the incidence of postoperative complications were compared between the two groups.Results BCVA showed significant improvement after surgery in both groups(P<0.05),and postoperative BCVA in the study group was higher than that in the control group(P<0.05).There was no significant difference in IOP between the two groups(P>0.05).ACD and subjective visual quality were increased,and ELP was decreased after surgery in both groups(P<0.05),and these indexes in the study group were superior to those in the control group after surgery(P<0.05).The incidence of complications,such as retinal detachment,corneal edema,and corneal endothelial decompensation in the study group was lower than that in the control group(P<0.05).Conclusion Phacoemulsification with IOL implantation combined with capsular tension rings can improve visual acuity and intraocular structural stability in patients with high myopia and cataract.It is a recommended treatment.

Tumor-associated macrophages(TAMs)are the predominant cell group in the tumor microenvironment(TME)and are the most important regulatory cells of immune system suppression and tumor cell proliferation in TIME.Src homology-2 domain-containing protein tyrosine phosphatase 2(SHP-2)is a non-receptor protein tyrosine phosphatase that plays an important role in the transmission of signals from the cell surface to the nucleus.SHP-2 is a key intracellular regulatory factor mediating cell proliferation and differentiation and is involved in a variety of growth factor and cytokine signaling pathways linking the cell surface to the nucleus.Recent studies have shown that SHP-2 is a key enzyme in determining the function of TAMs,but because of its variable function,it plays different or even opposite roles in different solid TMEs.This paper reviews the function of SHP-2 in TAMs and related solid tumors to provide a comprehensive reference for tumor immunity and targeted therapy research.

Objective:To explore the application value of serum melanoma-associated antigen A3 (MAGEA3) and human epididymis protein 4 (HE4) in the auxiliary diagnosis of lung cancer patients.Methods:A total of 134 patients with lung cancer who underwent treatment at Qingdao Central Hospital, University of Health and Rehabilitation Sciences from January 2021 to January 2024 were selected as study subjects (study group), and 158 healthy people who underwent physical examination during the same period were selected as control group. Enzyme linked immunosorbent assay was applied to measure the serum level of MAGEA3 and HE4. According to the median MAGEA3 and HE4 levels before treatment of the study group, lung cancer patients were divided into MAGEA3 high level group (≥58.69 pg/ml, n=66), low level group (<58.69 pg/ml, n=68) and HE4 high level group (≥125.04 pmol/L, n=69) and low level group (<125.04 pmol/L, n=65). Receiver operator characteristic (ROC) curves were plotted to evaluate the diagnostic performance of serum MAGEA3 and HE4 level for lung cancer before treatment. Results:Serum MAGEA3 and HE4 levels before treatment in the study group were (58.69±16.14) pg/ml and (125.04±28.49) pmol/L, and those in the control group were (43.52±14.83) pg/ml and (96.85±22.33) pmol/L, respectively. The levels of MAGEA3 and HE4 in the study group were significantly higher than those in the control group, with statistically significant differences ( t=8.36, P<0.001; t=9.47, P<0.001). Serum MAGEA3 and HE4 levels after treatment in the study group were (46.73±15.42) pg/ml and (113.26±24.73) pmol/L, respectively, serum MAGEA3 and HE4 levels after treatment were significantly lower than those before treatment, with statistically significant differences ( t=16.07, P<0.001; t=9.27, P<0.001). There were significant differences in differentiation degree ( χ2=6.20, P=0.013), TNM staging ( χ2=7.27, P=0.007) and lymph node metastasis ( χ2=7.07, P=0.008) of lung cancer patients between the MAGEA3 high level group and the low level group before treatment. There were significant differences in differentiation degree ( χ2=4.93, P=0.026), TNM staging ( χ2=7.31, P=0.007) and lymph node metastasis ( χ2=9.85, P=0.002) of lung cancer patients between the HE4 high level group and the low level group before treatment. The ROC curve analysis showed that, the area under the curve (AUC) of serum MAGEA3 and HE4 alone for diagnosing lung cancer before treatment were 0.77 (95% CI: 0.72-0.83) and 0.76 (95% CI: 0.70-0.81), and the AUC of the above two combined for diagnosing lung cancer was 0.87 (95% CI: 0.83-0.91), and the combined diagnosis value of the two was higher than that of MAGEA3 ( Z=2.92, P=0.003) and HE4 ( Z=3.24, P=0.001) alone. Conclusion:Compared with healthy people, serum MAGEA3 and HE4 levels before treatment of lung cancer patients are significantly increased, and serum MAGEA3 and HE4 levels are significantly lower after treatment than those before treatment. The combination of the two is more effective in diagnosis for lung cancer and can be used as an auxiliary diagnostic tool for lung cancer patients.

【Objective】 To analyze the basic characteristics of whole blood donors from blood stations before and after the outbreak of COVID-19. 【Methods】 After excluding invalid data, data related to the basic characteristics of whole blood donors collected from 26 blood stations in China during 2018 to 2021 were statistically analyzed, including the trend of total whole blood donors, the number of repeated blood donors, the frequency of blood donation, the average age of donors and the recruitment of first-time blood donors. 【Results】 Affected by the epidemic, 8 out of 14 indicators were with large variations, accounting for 57%. The overall growth rate of total whole blood donors during the epidemic was higher than before the epidemic (P<0.05).The number of repeated blood donors has shown an increased trend, with a higher number during the epidemic than before (P<0.05). The frequency of blood donation was lower during the epidemic than before(P<0.05).Average ages of blood donors and female blood donors fluctuated widely during the epidemic, both higher than those before the epidemic(P<0.05).The donation rate of first-time blood donors <25 years old and ≥25 years old varied widely and irregularly during the epidemic (both P<0.05). The percentage of first-time blood donors fluctuated irregularly during the epidemic, with overall percentage lower than that before the epidemic(P<0.05). 【Conclusion】 Whole blood donors from 26 blood stations increased after the outbreak of COVID-19, and some indicators in certain areas showed significant fluctuations during the epidemic.

Objective:To evaluate the residual risk (RR) of transfusion transmitted HIV (TT-HIV) after the implementation of nucleic acid amplification test (NAT) in blood screening test among blood centers in China.Methods:The data of blood donors and HIV infection markers from 2017 to 2020 were collected from 28 blood centers via the Platform of Comparison of blood establishments Practice in Chinese Mainland. The new infection rate/window period mathematical model was used for two types of blood screening strategies, namely, two rounds ELISA plus individual NAT take turn with pooling NAT (2ELISA+ ID-NAT/MP-NAT) and two ELISA plus one round pooling NAT (2ELISA+ MP-NAT), and the RR of HIV infection was estimated also based on first donors (FDs) and repeated donors (RDs) in different blood donation years. T-test analyses were conducted for comparing TT HIV RR among FDs and RDs in different blood donation years with two blood screening strategies, and the variation trend of RR in HIV test was observed.Results:From 2017 to 2020, the RR of FDs in 2ELISA+ ID-NAT/MP-NAT blood screening strategy was 2.869/10 6 person-year, 3.795/10 6 persons-year, 3.879/10 6 person-year, and 2.890/10 6 person-year respectively. The RR of RDs was 1.797/10 6 person-year, 1.502/10 6 person-year, 1.857/10 6 person-year, and 1.483/10 6 person-year respectively. Significant difference exists between RR of FDs and RDs, with F=9.898 and p<0.05. In 2ELISA+ MP-NAT strategy, the RR of FDs was 3.508/10 6 person-year, 1.868/10 6 person-year, 2.204/10 6 person-year, and 1.765/10 6 person-year respectively. The RR of RDs was 0.948/10 6 person-year, 0.926/10 6 person-year, 0.748/10 6 person-year, and 0.682/10 6 person-year respectively. Statistical difference existed between RR of FDs and RDs, with F=17.126 and P<0.05. There was no significant difference between the RR of FDs in these two strategies with F=3.493 and P>0.05, while there was a difference between the RR of RDs in these two strategies with F=24.516 and P<0.05, and a difference between the RR of total donors (TDs) in these two strategies F=20.216 and P<0.05. Conclusions:The RR of TT HIV significantly decreased after the introduction of NAT into blood test among blood centers in China. There were some differences in the RR of HIV testing among different blood screening strategies. There could be significant differences in the RR of HIV testing among different groups of blood donors. Compared with FDs, RDs is the low risk group for HIV.

Osteofacial compartment syndrome (OCS) is one of the serious complications in traumatic orthopedics. If not treated in time, OCS may result in irreversible damage to nerve and muscle,even amputation or death in serious condition. 5P presents to be the classic clinical diagnosis of OCS, but it is highly subjective and cannot timely and accurately judge the progression of the disease. Intracompartment pressure manometry is the main auxiliary method for the diagnosis of OCS. Although there are many manometry methods, there is still no authoritative pressure threshold as the diagnosis standard. Clinicians often aggressively perform fasciotomy to avoid serious complications, leading to unnecessary fasciotomy. The authors retrospectively reviewed the data of patients with OCS treated at Air Force Hospital of Eastern Theater of PLA from March 2010 to March 2020 and found that some patients with OCS had gradual alleviation of clinical symptoms after appropriate conservative treatments such as brace releasing, limb stabilization and swelling subsidence, with no need of fasciotomy. However, the symptoms of some patients progressively aggravated after the above-mentioned traditional treatments and timely fasciotomy was required. The authors graded the severity of OCS and proposed for the first time the OCS grading criteria according to quantitative clinical results and quantitative indicators such as ratio of mean blood flow velocity of bilateral arteries and pulse wave changes, aiming to take corresponding intervention measures for patients with different OCS classifications, carry out more precise treatment and avoid unnecessary fasciotomy.

Objective:To learn about the status of thyroid function and intelligence quotient (IQ) of children in areas with different iodine nutrition levels in Xinjiang Uygur Autonomous Region, and to explore the health risk of children with median urinary iodine of 200 - 299 μg/L, and to provide a basis for scientific iodine supplementation.Methods:In May 2019, in Xinjiang Uygur Autonomous Region, Altay Prefecture and Kashgar Prefecture were selected, where the median urinary iodine of children aged 8 to 10 years were 100 - 199 and 200 - 299 μg/L for three consecutive years (2017 - 2019). A stratified random sampling method was used to select 400 children aged 8 to 10 years in each of the two regions, urine and blood samples were collected to detect urinary iodine and thyroid function [thyrotropin stimulating hormone (TSH), free thyroxine (FT 4), free triiodothyronine (FT 3), anti-thyroglobulin antibody (TgAb), and anti-thyroperoxidase antibody (TPOAb)]. At the same time, children's IQ was measured and determined by Second Revision of Combined Raven's Test (CRT-C2) in China and Second Revision of Combined Raven's Test for Children-the Rural, in China (CRT-RC2). Results:The median urinary iodine of children aged 8 to 10 years in Altay Prefecture and Kashgar Prefecture was 188.6 and 250.1 μg/L, respectively. There was no statistically significant difference in thyroid function indexes TSH and FT 3 levels between the two regions ( Z = - 0.58, t = 0.49, P > 0.05), while there was statistically significant difference in FT 4 level ( t = 60.08, P < 0.001). There was no statistically significant difference in TgAb positive rate [3.6% (14/394), 4.0% (16/399)] between the two regions (χ 2 = 0.11, P = 0.736), but the difference of TPOAb positive rate [9.6% (38/394), 30.6% (122/399)] was statistically significant (χ 2 = 53.93, P < 0.001), while the difference of dual antibody positive rate [0.8% (3/394), 2.0% (8/399)] was not statistically significant ( P = 0.134). There was no statistically significant difference in the detection rates of subclinical hypothyroidism [8.9% (35/394), 11.0% (44/399)], subclinical hyperthyroidism [1.0% (4/394), 1.3% (5/399)] and hyperthyroidism [0.3% (1/394), 0.8% (3/399)] in children between the two regions ( P > 0.05). The IQ results of children in the two regions were 96.55 ± 11.36 and 89.57 ± 12.35, respectively, and there was no significant difference between them ( t = 2.79, P = 0.095). Conclusions:The thyroid function status of children is similar in the two regions with median urinary iodine of 100 - 199 μg/L and 200 - 299 μg/L in children aged 8 to 10 years, but the TPOAb positive rate is significantly different. Children whose iodine nutritional level is at or above the appropriate level have no obvious changes in intelligence. It is suggested that median urinary iodine at 200 - 299 μg/L is a relatively safe iodine nutrition state.
