Objective To investigate the status of familial aggregation of Helicobacter pylori (Hp) infection in Jinniu District, Chengdu, and analyze its risk factors so as to provide a basis for developing prevention and control strategies of family aggregation of Hp infection. Methods A total of 172 subjects in the Second Affiliated Hospital of Chengdu Medical College · 416 Hospital of Nuclear Industry from January 2022 to January 2023 were selected as the research subjects. All subjects underwent 13C-urea breath test (13C-UBT) to diagnose whether there was Hp infection. Analyze the current situation of family aggregation of Hp infection in the region, collect general data of survey subjects, analyze the relevant factors affecting Hp family aggregation infection, and develop prevention and control strategies based on this. Results A total of 242 people from 97 households were surveyed, and the Hp family aggregation rate was 29.33%. Univariate analysis showed that there were statistically significant differences in family aggregation of Hp infection in terms of different age groups (χ²=9.719, P=0.008), marital status (χ²=8.496, P=0.014), occupations (χ²=19.462, P<0.001), frequencies of dining out (χ²=5.457, P=0.019), previous Hp test results (χ² =4.131, P=0.042) and test results after treatment (χ²=12.000, P=0.001), with statistical significance (P<0.05). Multivariate logistic regression analysis showed that the frequency of dining out 2 days or more per week and a positive Hp test results in the past were risk factors for family aggregation of Hp infection, while the occupation of teachers/medical staff/management/technology personnel and a negative Hp results after treatment were protective factors (P<0.05). Conclusion Family aggregation of Hp infection is related to family members' occupation, frequency of dining out, previous Hp test results and Hp test results after eradication, which deserves attention in clinical practice.

Objective:To investigate the prognostic value of serum suppressor of cytokine signaling 3 (SOCS3) and thioredoxin-interacting protein (TXNIP) levels in transcatheter arterial chemoembolization (TACE) treatment of hepatocellular carcinoma (HCC) .Methods:A total of 107 HCC patients who underwent TACE treatment in Wuhan Hanyang Hospital from December 2019 to July 2021 were selected as the observation objects. According to the situation after TACE treatment, the patients were divided into poor prognosis group ( n=47) and good prognosis group ( n=60). Serum SOCS3 and TXNIP levels were detected by enzyme-linked immunosorbent assay, the prognostic factors were analyzed by logistic regression. The predictive value of serum SOCS3 and TXNIP levels before treatment for TACE treatment prognosis in patients with HCC was analyzed by receiver operator characteristic (ROC) curve. Results:There were no statistically significant differences between good prognosis group and poor prognosis group in age ( χ2=0.56, P=0.453), gender ( χ2=0.06, P=0.800), tumor size ( χ2=1.46, P=0.227), Child-Pugh grade ( χ2=0.26, P=0.608), tumor number ( χ2=0.77, P=0.382), cirrhosis ( χ2=0.03, P=0.860), TACE times ( χ2=0.16, P=0.691), alpha-fetoprotein level before treatment ( χ2=0.79, P=0.374), and hepatitis B surface antigen ( χ2=0.58, P=0.446). The proportion of TNM stage Ⅲ patients in the poor prognosis group (57.45%, 27/47) was higher than that in the good prognosis group (25.00%, 15/60), with a statistically significant difference ( χ2=11.64, P=0.001). The serum levels of SOCS3 and TXNIP in the good prognosis group before treatment were (114.34±20.39) and (45.64±6.41) pg/ml, respectively, while those in the poor prognosis group were (82.83±15.97) and (34.82±6.36) pg/ml, respectively, serum SOCS3 and TXNIP levels in the poor prognosis group were lower than those in the good prognosis group, with statistically significant differences ( t=8.71, P<0.001; t=8.70, P<0.001). After treatment, the serum SOCS3 and TXNIP levels in the good prognosis group were (139.65±24.32) and (64.75±7.58) pg/ml, respectively, while those in the poor prognosis group were (92.41±16.15) and (41.74±7.23) pg/ml, serum SOCS3 and TXNIP levels in the poor prognosis group were lower than those in the good prognosis group, with statistically significant differences ( t=11.48, P<0.001; t=15.90, P<0.001). Serum SOCS3 and TXNIP levels in both groups were significantly higher after treatment than before (all P<0.05). Multivariate analysis showed that TNM stage ( OR=2.53, 95% CI: 1.27-5.02, P=0.008) was an independent risk factor for prognosis in HCC patients after TACE treatment, SOCS3 ( OR=0.65, 95% CI: 0.44-0.96, P=0.031) and TXNIP ( OR=0.57, 95% CI: 0.36-0.89, P=0.014) were independent protective factors for prognosis in HCC patients after TACE treatment. ROC curve analysis showed that the sensitivity and specificity of the combined detection of serum SOCS3 and TXNIP before treatment in predicting prognosis of TACE treatment in HCC patients were 81% and 92%, respectively, the area under the curve was 0.92 (95% CI: 0.85-0.96) . Conclusion:The low levels of serum SOCS3 and TXNIP before TACE treatment in HCC patients may indicate poor prognosis after TACE treatment. The combined detection of the two has certain predictive value for judging the prognosis of HCC patients after TACE treatment.

Alcoholic liver disease (ALD) is a growing global health concern, and its early pathogenesis includes steatosis and steatohepatitis. Inhibiting lipid accumulation and inflammation is a crucial step in relieving ALD. Evidence shows that puerarin (Pue), an isoflavone isolated from Pueraria lobata, exerts cardio-protective, neuroprotective, anti-inflammatory, antioxidant activities. However, the therapeutic potential of Pue on ALD remains unknown. In the study, both the NIAAA model and ethanol (EtOH)-induced AML-12 cell were used to explore the protective effect of Pue on alcoholic liver injury in vivo and in vitro and related mechanism. The results showed that Pue (100 mg·kg^-1) attenuated EtOH-induced liver injury and inhibited the levels of SREBP-1c, TNF-α, IL-6 and IL-1β, compared with silymarin (Sil, 100 mg·kg^-1). In vitro results were consistent within vivo results. Mechanistically, Pue might suppress liver lipid accumulation and inflammation by regulating MMP8. In conclusion, Pue might be a promising clinical candidate for ALD treatment.

Objective:To investigate the association between skin advanced glycation end products (AGEs) and carotid atherosclerosis (AS) in subjects with normal glucose regulation (NGR).Methods:This was a cross-sectional study. Data from the Health Management Center of the First Affiliated Hospital of University of Science and Technology between January 2019 to June 2019 were collected. A total of 902 NGR subjects aged 40-79 were enrolled and categorized into control group (530 cases), carotid intima-media thickness (IMT) thickening group (150 cases), and carotid atherosclerosis plaque group (222 cases) based on the carotid ultrasound results. Data as follows were collected, gender, age, blood pressure, body mass index (BMI), triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), fasting blood glucose (FPG), glycosylated hemoglobin (HbA 1c) and skin AGEs. Comparison via ANOVA analysis were carried out among the 3 groups. Logistic regression analysis was used to screen the independent influencing factors of carotid atherosclerosis plaque. Spearman correlation analysis was used to evaluate the correlation between AGEs and other parameters, and receiver operating characteristic (ROC) curve was used to evaluate the efficiency of skin AGEs in predicting carotid atherosclerosis plaque in NGR subjects. Results:Among the control group, IMT thickening group and carotid atherosclerosis plaque group, gender, age, systolic blood pressure (SBP), diastolic blood pressure (DBP), TC, LDL-C, FPG, HbA 1c, AGEs were significantly different (all P<0.05). Compared with IMT thickening group, the age, SBP and AGEs of carotid atherosclerotic plaque group were higher [55 (50, 60) vs 53 (49, 56) year; 132 (122, 141) vs 126 (115, 142) mmHg(1 mmHg=0.133 kPa); 74 (67, 81) vs 72 (67, 78) AU] (all P<0.001); compared with the control group, age, LDL-C, HbA 1c and AGEs of IMT thickening group were higher [53 (49, 56) vs 48 (45, 52) year; (2.8±0.7) vs (2.7±0.7) mmol/L; 5.4% (5.2, 5.6)% vs 5.4% (5.1, 5.6)%; 72 (67, 78) vs 70 (66, 76)] (all P<0.05). Age ( OR=1.179, 95% CI: 1.107-1.255), SBP ( OR=1.045, 95% CI: 1.013-1.077), LDL-C ( OR=2.028, 95% CI: 1.036-3.969), AGEs ( OR=1.049, 95% CI: 1.000-1.100) were independent influencing factors of carotid atherosclerotic plaque in population with normal glucose regulated (all P<0.05). AGEs was positively correlated with age, HbA 1c and carotid atherosclerosis plaque ( r=0.407, 0.092, 0.172) (all P<0.01). The area under the ROC curve of skin AGEs for identifying carotid atherosclerotic plaque in NGR population was 0.650 (95% CI 0.601-0.698), the best cutoff value was 70.5, the sensitivity was 65.8%, and the specificity was 56.9%. Conclusion:Skin AGEs level is closely associated with the occurrence of carotid atherosclerosis in NGR subjects.

Objective:To summarize clinical characteristics of and treatment experience with patients with critical illnesses in a dermatological ward.Methods:All patients with serious or life-threatening conditions, who were hospitalized at the dermatological ward of the Second Xiangya Hospital of Central South University from July 9, 2011 to December 31, 2020, were collected, and their clinical data were retrospectively analyzed. Demographic characteristics, disease types and proportions, main complications, causes of serious or life-threatening conditions, important treatment measures and outcomes were summarized, and causes of death were also analyzed and discussed.Results:A total of 1 057 patients with critical illnesses were collected, with a male-to-female ratio of 1∶1.11, and 64.81% of them aged 18 to 65 years. The types of diseases mainly included drug eruptions (332 cases) , connective tissue diseases (226 cases) , bullous skin diseases (104 cases) , psoriasis (57 cases) , erythroderma (45 cases) , infectious skin diseases (67 cases) , etc. Among them, psoriasis (39 cases) and erythroderma (32 cases) mostly occurred in males, and connective tissue diseases (168 cases) mostly occurred in females. Common complications mainly involved infections, important organ damage or dysfunction, hypoalbuminemia, and fluid, electrolyte and acid-base imbalances. A total of 94 patients were diagnosed with life-threatening conditions, which were found to be mainly caused by primary skin diseases, hematologic abnormalities, respiratory failure, nervous system abnormalities, renal failure, sepsis, fluid, electrolyte and acid-base imbalances, etc. During the management of critical illnesses, 43 patients were treated with high-dose glucocorticoid pulse therapy, 264 were treated with gamma-globulin pulse therapy, 355 were transfused with other blood products, and 34 received special therapies such as hemoperfusion/immunoadsorption therapy, plasma exchange, dialysis, artificial liver support therapy; 42 patients were transferred to the intensive care unit (ICU) , 12 were transferred to the department of surgery for operations, and 12 were transferred to the department of obstetrics and gynecology for delivery or induction of labor. After treatment, 989 patients (93.57%) achieved improvement and were discharged. A total of 14 patients (1.32%) died, of whom 7 died of secondary sepsis, 2 died of severe pulmonary infections, 2 died of asphyxia caused by respiratory mucosa shedding-induced airway obstruction, the other 3 died of gastrointestinal hemorrhage, cerebral hemorrhage and neuropsychiatric systemic lupus erythematosus, respectively.Conclusions:Critical cases in the dermatological ward mainly suffered from serious skin diseases such as severe drug eruptions, connective tissue diseases and bullous skin diseases, as well as complications such as severe underlying diseases, severe organ dysfunction, sepsis or severe fluid, electrolyte and acid-base imbalances. In terms of treatment, it is of critical significance to make a clear diagnosis and assess the severity of disease as early as possible, monitor and prevent possible complications, and to consult with specialists in relevant disciplines in time.

Objective:To explore the relationships between serum lipids, CA153 level and breast cancer incidence and clinicopathological features of patients.Methods:A total of 198 patients with breast cancer diagnosed and treated at Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School were enrolled as the case group, and 198 healthy women were selected with 1∶1 age pairing as controls. Five milliliters of fasting venous blood was collected to measure serum lipids levels in all subjects and CA153 levels in breast cancer patients. The difference of serum lipids levels between the two groups was compared. Logistic regression model was used to analyze the risk factors of breast cancer. For 165 breast cancer patients who did not receive neoadjuvant chemotherapy, independent sample t-test was used to compare serum lipids and CA153 levels in breast cancer patients with different pathological features, and Pearson correlation analysis was used to calculate the correlation between variables and CA153. Results:The triglyceride (TG) levels in the case group and the control group were (1.22±0.73) mmol/L and (1.06±0.52) mmol/L respectively, and the difference was statistically significant ( t=2.559, P=0.011); the total cholesterol (TC) levels were (4.47±0.86) mmol/L and (4.99±0.80) mmol/L respectively, and the difference was statistically significant ( t=-6.228, P<0.001); the high-density lipoprotein cholesterol (HDL-C) levels were (1.32±0.34) mmol/L and (1.53±0.38) mmol/L respectively, and the difference was statistically significant ( t=-5.913, P<0.001). Higher TC and HDL-C levels were independent protective factors for breast cancer ( OR=0.350, P<0.001; OR=0.531, P=0.013). The TC levels in lymph node positive and lymph node negative patients were (4.36±0.73) mmol/L and (4.67±0.83) mmol/L respectively, and the difference was statistically significant ( t=-2.518, P=0.013); low-density lipoprotein cholesterol (LDL-C) levels were (2.53±0.58) mmol/L and (2.77±0.70) mmol/L respectively, and the difference was statistically significant ( t=-2.312, P=0.022). The TC levels in patients with stage Ⅰ and stage Ⅱ/Ⅲ were (4.90±0.89) mmol/L and (4.46±0.76) mmol/L respectively, and the difference was statistically significant ( t=2.855, P=0.005); LDL-C levels were (2.95±0.71) mmol/L and (2.60±0.63) mmol/L respectively, and the difference was statistically significant ( t=2.705, P=0.008). The level of CA153 in triple-negative breast cancer patients [(14.94±7.45) U/ml] was significantly higher than that in non-triple-negative breast cancer patients [(11.96±5.96) U/ml], and the difference was statistically significant ( t=2.359, P=0.020). The level of CA153 was positively correlated with the level of TG ( r=0.167, P=0.032). Conclusion:Dyslipidemia is associated with an increased risk of breast cancer. The levels of serum lipids vary among patients with different lymph node status and tumor stages. CA153 level is positively correlated with TG level to some extent.

Objective: To study the effects of resistant dextrin (RD) on liver fat deposition in high-fat diet-fed (HFD) mice, and to further explore whether it can regulate the AMPK signaling pathway. Methods: Thirty-six 4-week-old male C57BL/6 mice were randomly divided into three groups: normal control group (chow), high-fat diet group (HFD), and high-fat diet+ resistant dextrin group (HFD+ RD, 10 g·kg^-1·d^-1). After 12 weeks of intervention, the liver tissues and serum samples were collected. Serum triglyceride (TG), total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), aspartate aminotransferase (AST), alanine transaminase (ALT) levels and liver TG were measured. Liver tissue HE and oil red O staining were performed to observe hepatocyte steatosis and liver fat deposition. Quantitative real-time PCR was performed to detect the relative expression of fatty acid synthesis related genes SREBP1, ACC, SCD1 in the liver tissue, and Western blot was performed to detect relative protein levels of pAMPK, SREBP1, Fasn, and ACC in the liver. Results: Compared with chow group, the body weight gain, fasting blood glucose (FBG), serum TC, LDL-C, HDL-C, and ALT levels were increased in HFD group (P<0.01), and serum AST level was also increased (P<0.05). Moreover, liver oil red O staining revealed that liver fat deposition was much more obvious in HFD group than that in chow group, and liver TG was also increased in HFD group (P<0.01). The mRNA levels of SREBP1 and ACC were increased in HFD group compared with that in chow group, and the protein level of pAMPK was reduced in HFD group (P<0.05). As compared with HFD group, the body weight gain, serum TG, TC, LDL-C, HDL-C and ALT levels were significantly reduced in RD group (P<0.01), and FBG level was also reduced (P<0.05). Moreover, RD treatment alleviated liver fat deposition and TG accumulation (P<0.01). The mRNA levels of SREBP1, ACC, and SCD1 were all reduced in RD group compared with HFD group. The protein level of pAMPK was increased, and the expression of Fasn was reduced with RD treatment (P<0.01). Conclusion Resistant dextrin improves liver fat deposition and activates the AMPK signaling pathway in HFD-fed mice.
