Background::Copper and zinc are involved in the development of multiple malignancies; yet, epidemiological evidence on hepatocellular carcinoma (HCC) is limited. This study aimed to investigate the association between dietary intake and serum levels of copper and zinc with the risk of HCC.Methods::A total of 434 case-control pairs matched for sex and age (±1 year) were included in this study. Cases with newly diagnosed HCC were from the Guangdong Liver Cancer Cohort (GLCC) study, and healthy controls were from the Guangzhou Nutrition and Health Study (GNHS). A semi-quantitative 79-item food frequency questionnaire (FFQ) was used to assess habitual dietary intakes of copper and zinc. Serum levels of copper and zinc were measured by using inductively coupled plasma mass spectrometry. The copper (Cu)/ zinc (Zn) ratio was computed by dividing copper levels by zinc levels. Conditional logistic regression models were performed to calculate the odds ratio (OR) and 95% confidence intervals (CI) for per 1 standard deviation increase (per-SD increase) in copper and zinc levels.Results::Higher dietary intake (OR per-SD increase = 0.65, 95% CI: 0.44, 0.96, Ptrend = 0.029) and serum levels of zinc (OR per-SD increase = 0.11, 95% CI: 0.04, 0.30, Ptrend <0.001) were both associated with a lower risk of HCC. Subgroup analyses showed that the inverse association was only pronounced in men but not in women ( Pinteraction = 0.041 for dietary zinc intake and 0.010 for serum zinc levels). Serum copper levels (OR per-SD increase = 2.05, 95% CI: 1.39, 3.03, Ptrend = 0.020) and serum Cu/Zn ratio (OR per-SD increase = 6.53, 95% CI: 2.52, 16.92, Ptrend <0.001) were positively associated with HCC risk, while dietary copper intake and dietary Cu/Zn ratio were not associated with HCC risk. Conclusion::Zinc may be a protective factor for HCC, especially among men, but the effects of copper on HCC risk are not clear.

[Objective]To investigate the current situation of adverse events related to acupuncture that have been reported domestically and internationally over the past eleven years,so as to provide better guidance for clinical practices,standardize acupuncture operations,and minimize the associated risks.[Methods]This study looked for cases of adverse events related to acupuncture treatment in China National Knowledge Infrastructure(CNKI),Wanfang Data Knowledge Service Platform,VIP Database and China Biomedical Literature Service System,as well as the PubMed database. The collected case reports were then subjected to statistical analysis to determine the types of adverse events,the number of cases,the prognosis,and the causes.[Results]A total of 109 valid documents and 223 cases were included. The number of reported acupuncture adverse events varied over the past 11 years,showing an increasing trend in 2023. There were eight main types of adverse events identified,including organ injury,infection,syncope,nerve injury,vascular injury,eye injury,needle breakage and others. Among these,infection(37.67％),organ injury(32.74％),and vascular injury(9.42％) were the most commonly reported. The most severe adverse events included pneumothorax,acute peritonitis,vagus nerve injury,subarachnoid hemorrhage and ruptured cerebral arteriovenous malformation.[Conclusion]While the incidence of adverse events in acupuncture treatment is generally low,it is important to continue improving safety measures through standardized practices,strict sterilization protocols,thorough patient assessments,and enhanced education during needle retention. Healthcare providers should strive to enhance their techniques,have a deep understanding of patients' underlying conditions,and prioritize patient education to ensure the safety and effectiveness of acupuncture treatments.

Lung cancer is the most common cancer and the leading cause of cancer-related death in China. Early screening of lung cancer proves to be effective in improving its prognosis. The National Comprehensive Cancer Network (NCCN) has updated and released version 2, 2022 NCCN clinical practice guidelines for lung cancer screening in July, 2022. Based on high-quality clinical evidence and the latest research progress, the guidelines have developed and updated criteria for lung cancer screening which have been widely recognized by clinicians around the world. Compared with Chinese lung cancer screening guidelines, this article will interpret the updated content of the brand new 2022 NCCN screening guidelines, providing some reference for the current lung cancer screening practice in our country.

Objective:To investigate the influential factors of neonatal hypoxic ischemic encephalopathy (HIE), and compare the therapeutic effects of mild hypothermia at different time windows and between different degrees of disease severity.Methods:Eighty-two neonates with HIE who were admitted to Jiaxing Maternity and Child Health Care Hospital from January 2016 to October 2021 were included in the patient group, and 123 concurrent healthy neonates were included in the control group. The influential factors of neonatal HIE were analyzed. Sixty-five neonates who received HIE were divided into four groups according to the time length between symptom onset and hospital admission (< 6 hours and 6-12 hours) and disease severity: group I (admission time < 6 hours, mild, n = 20), group II (admission time < 6 hours, moderate to severe, n = 15), group III (admission time 6-12 hours, mild, n = 17), and group IV (admission time 6-12 hours, moderate to severe, n = 13). Amplitude-integrated electroencephalography (aGGE) score was used as the evaluation criteria. The therapeutic effects of mild hypothermia were compared between different time windows and between different degrees of HIE. Results:Multivariable logistic regression analysis results revealed that the influential factors of neonatal HIE included gestational hypertension, gestational diabetes, pregnancy examination, delivery methods, amniotic fluid contamination, abnormal fetal membranes (placenta or umbilical cord), fetal distress, and neonatal asphyxia ( P < 0.05). All 65 neonates with HIE underwent mild hypothermia treatment for 72 hours. Before treatment, aGGE score in groups I, II, III and IV was 6.02 ± 1.74 points, 2.43 ± 1.82 points, 5.23 ± 1.95 points, and 2.72 ± 1.76 points, respectively. After treatment, it was 8.13 ± 2.03 points, 6.47 ± 1.87 points, 7.86 ± 1.92 points, and 3.52 ± 1.95 points, respectively. There was significant difference in aGGE score between before and after treatment in groups I, II and III ( t = 2.87, 3.55, 3.15, all P < 0.05). aGGE score in group IV did not differ significantly between before and after treatment ( P > 0.05). Before treatment, aGGE score in children with moderate to severe HIE was lower than that in children with mild HIE. After treatment, there was no significant difference in aGGE score between groups II and III ( P > 0.05). Conclusion:Pregnant women with gestational hypertension and gestational diabetes should be given intensive monitoring and learn HIE related knowledge to increase the frequency of prenatal examinations. If amniotic fluid contamination, abnormal fetal membranes (placenta or umbilical cord), fetal distress, or neonatal asphyxia occurs, timely monitoring and corresponding interventions should be given to the fetus. Mild hypothermia therapy has a certain therapeutic effect on different degrees of HIE. For moderate to severe neonates, treatment should be started within 6 hours to ensure the therapeutic effects of mild hypothermia.

Objective: Although some studies have linked Asari Radix et Rhizoma (Asari Radix) administration to hepatocellular carcinoma (HCC), few studies have examined the association between the development of HCC and use of Asari Radix among patients in mainland China. This study aimed to evaluate the real-world association between Asari Radix and HCC in patients to strengthen the understanding of Asari Radix safety. Methods: A retrospective cohort study among hepatitis B virus (HBV)-monoinfected patients and non-HBV-monoinfected patients were performed. Patients over 18 years of age were eligible for inclusion. Prescription records of inpatients and outpatients were inquired to distinguish Asari Radix users and nonusers. The risk of developing HCC among Asari Radix users and nonusers in the HBV cohort and the non-HBV cohort was analyzed. Results: There were 49 500 HBV and 133 148 non-HBV patients involved in the two cohorts. Among HBV patients (2 901 users; 46 599 nonusers), the prevalence of HCC in Asari Radix users was lower than that in nonusers (145.70 vs. 265.43 per 10

Objective To explore the association between lipid profiles and left ventricular hypertrophy in a Chinese general population. Methods We conducted a retrospective observational study to investigate the relationship between lipid markers [including triglycerides, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein (HDL) cholesterol, non-HDL-cholesterol, apolipoprotein A-I, apolipoprotein B, lipoprotein[a], and composite lipid profiles] and left ventricular hypertrophy. A total of 309,400 participants of two populations (one from Beijing and another from nationwide) who underwent physical examinations at different health management centers between 2009 and 2018 in China were included in the cross-sectional study. 7,475 participants who had multiple physical examinations and initially did not have left ventricular hypertrophy constituted a longitudinal cohort to analyze the association between lipid markers and the new-onset of left ventricular hypertrophy. Left ventricular hypertrophy was measured by echocardiography and defined as an end-diastolic thickness of the interventricular septum or left ventricle posterior wall > 11 mm. The Logistic regression model was used in the cross-sectional study. Cox model and Cox model with restricted cubic splines were used in the longitudinal cohort. Results In the cross-sectional study, for participants in the highest tertile of each lipid marker compared to the respective lowest, triglycerides [odds ratio (OR): 1.250, 95％CI: 1.060 to 1.474], HDL-cholesterol (OR: 0.780, 95％CI: 0.662 to 0.918), and lipoprotein(a) (OR: 1.311, 95％CI: 1.115 to 1.541) had an association with left ventricular hypertrophy. In the longitudinal cohort, for participants in the highest tertile of each lipid marker at the baseline compared to the respective lowest, triglycerides [hazard ratio (HR): 3.277, 95％CI: 1.720 to 6.244], HDL-cholesterol (HR: 0.516, 95％CI: 0.283 to 0.940), non-HDL-cholesterol (HR: 2.309, 95％CI: 1.296 to 4.112), apolipoprotein B (HR: 2.244, 95％CI: 1.251 to 4.032) showed an association with new-onset left ventricular hypertrophy. In the Cox model with forward stepwise selection, triglycerides were the only lipid markers entered into the final model. Conclusion Lipids levels, especially triglycerides, are associated with left ventricular hypertrophy. Controlling triglycerides level potentiate to be a strategy in harnessing cardiac remodeling but deserve to be further investigated.

Since December 2019, a novel coronavirus (2019-nCoV, SARS-CoV-2) pneumonia (COVID-19) outbreak has occurred in Wuhan, Hubei Province, and the epidemic situation has continued to spread. Such cases have also been found in other parts of the country. The spread of the novel coronavirus pneumonia epidemic has brought great challenges to the clinical practice of thoracic surgery. Outpatient clinics need to strengthen the differential diagnosis of ground glass opacity and pulmonary plaque shadows. During the epidemic, surgical indications are strictly controlled, and selective surgery is postponed. Patients planning to undergo a limited period of surgery should be quarantined for 2 weeks and have a nucleic acid test when necessary before surgery. For patients who are planning to undergo emergency surgery, nucleic acid testing should be carried out before surgery, and three-level protection should be performed during surgery. Patients who are planning to undergo emergency surgery in the epidemic area should be confirmed with or without novel coronavirus pneumonia before operation, and perform nucleic acid test if necessary. Surgical disinfection and isolation measures should be strictly carried out. Among postoperative patients, cases with new coronavirus infection were actively investigated. For the rescue of patients with novel coronavirus infection, attention needs to be paid to prevention and treatment and related complications, including mechanical ventilation-related pneumothorax or mediastinal emphysema, and injury after tracheal intubation.

Objective To observe the clinical effect of Qingre-Jiangni-Zhixue decoction combined with omeprazole sodium on acute non-variceal upper gastrointestinal bleeding. Methods A total of 64 patients with acute non-variceal upper gastrointestinal bleeding were divided into the observation group and control group according to random number table method, with 32 cases in each group. The control group was given the routine clinical treatment combined with omeprazole sodium, and the observation group was given Qingre-Jiangni-Zhixue decoction on the basis of the control group. After 7 days of continuous treatment, the basic clinical indexes (hemostasis time, blood transfusion volume, hospitalization time, 72 hours hemostasis rate, rebleeding rate), oxidative stress indexes (cortisol, malondialdehyde, antidiuretic hormone, blood glucose) and serum inflammatory factors (hs-CRP, TNF-α, IL-1β) were observed before and after treatment, and the clinical efficacy were evaluated. Results The total effective rate of the observation group was 90.6% (29/32), which was significantly higher than that of the control group 71.9% (23/32), with statistically significant (χ2=4.730, P=0.029). After treatment, the hemostasis time (18.86 ± 2.97 h vs. 29.12 ± 4.07 h, t=7.354),blood transfusion volume (559.32 ± 67.17 ml vs. 612.73 ± 75.81 ml, t=11.032),hospitalization time (5.43 ± 0.67 d vs. 9.26 ± 1.15 d, t=5.871) of the observation group were significantly lower than those of the control group (P<0.05). The 72 h hemostasis rate of the observation group was 3.1%, which was significantly lower than that of the control group 21.9%, with statistically significant (χ2=5.143, P<0.05). The rebleeding rate of the observation group was 96.9%, which was significantly higher than that of the control group 81.3% (χ2=4.010, P=0.045). After treatment, the cortisol level, the malondialdehyde level, blood glucose, antidiuretic hormone of the observation group were lower than those of the control group (t were 8.106, 4.976, 4.842, 5.093, all Ps<0.01). After treatment, the hs-CRP, serum TNF-α, serum IL-1β of the observation group were lower than those of the control group (t were 5.506, 4.983, 7.962, all Ps<0.01). Conclusions The application of Qingre-Jiangni-Zhixue decoction combined with omeprazole sodium can inhibit the expression of serum inflammatory cytokines in patients with acute non-variceal upper gastrointestinal bleeding, reduce the oxidative stress injury caused by bleeding, and improve the hemostatic efficiency.

Objective To investigate the distribution characteristics and risk factors of intracranial and extracranial aterial lesions in Chinese patients with ischemic stroke . Methods In this multi‐center study ,2 310 continuously inpatients with ischemic stroke diagnosed in 20 stroke screening and prevention project base hospitals from June 2015 to M ay 2016 were enrolled . Carotid ultrasonography and transcranial color‐coded sonography or transcranial Doppler were performed in all patients to confirm the presence of cerebral artery stenosis or occlusion . According to the distribution of lesions ,the subjects were divided into 2 groups :the simple intracranial artery stenosis group and the simple extracranial artery stenosis group . T he difference of risk factors between the two groups was compared . Results Of the 2 310 patients with ischemic stroke ,1 516 ( 65 .6% ) had simple intracranial artery stenosis and 794 ( 34 .4% ) had simple extracranial artery stenosis . T he incidence of anterior circulation artery stenosis was higher in the group of intracranial artery stenosis than that in the extracranial artery stenosis group ( 68 .1% vs 48 .7% , P ＜0 .001) . Posterior circulation artery stenosis and combined anterior with posterior circulation artery stenosis were more common in patients with extracranial artery stenosis group than those in intracranial artery stenosis group ( 36 .4% vs 22 .1% ,14 .9% vs 9 .8% ;all P ＜0 .001) . Univariate analysis of risk factors for stroke showed that patients with intracranial arterial stenosis had a higher prevelence of hypertension , diabetes ,obesity ,and family history of stroke ,and their systolic blood pressure ,diastolic blood pressure , body mass index ( BM I) ,fasting blood‐glucose ,glycosylated hemoglobin ,triacylglycerol ,total cholesterol , and low‐density lipoprotein cholesterol were significantly higher than those in the extracranial arterial stenosis group ( all P ＜ 0 .05 ) . T he proportion of elderly ( ≥ 65 years old ) ,male and smokers in the extracranial arterial stenosis group was significantly higher than that in the intracranial arterial stenosis group ( all P ＜0 .05) . Multivariate logistic regression analysis showed that elderly ( ≥65 years old) ,male , and smoking history were independent risk factors for extracranial arterial stenosis ( OR＝ 2 .012 ,1 .637 , 1 .325 ,respectively ;all P ＜0 .05) . While hypertension ,diabetes ,less physical activity ,and high BM I levels were independent risk factors for simple intracranial arterial disease ( OR ＝ 1 .301 ,1 .252 ,1 .248 ,1 .030 , respectively ;all P ＜0 .05) . Conclusions There are significant differences in the distribution characteristics and risk factors of intracranial and extracranial aterial lesions in patients with ischemic stroke in China .
