Objective This study aimed to explore the relationship between serum lipid and lipoprotein levels and occurrence of breast cancer, and relationship between serum lipid and lipoprotein levels and clinicopathological characteristics of breast cancer patients. Methods Clinical data of 788 patients with breast cancer and 395 patients with benign breast disease were retrospectively collected, who received treatment in The First Affiliated Hospital of Chongqing Medical University from January 2014 to March 2016, and to explore the relationship between levels of total cholesterol (TC)/triglyceride (TG)/high density lipoprotein cholesterol (HDL-c)/low density lipoprotein cholesterol (LDL-c) and occurrence of breast cancer/ clinicopathological characteristics of breast cancer patients. Results ① Influencing factors that affected the occurrence of breast cancer: multifactor logistic analysis showed that, height (OR=0.950, P=0.006), body mass index (OR=1.062, P=0.041), and serum LDL-c level (OR=1.349, P=0.016) were independent influencing factors for occurrence of breast cancer, people had high body mass index and higher level of serum LDL-c had high risk of breast cancer, but people had high height had low risk of breast cancer. ②Association analysis of serum lipid and lipoprotein levels and clinicopathological characteristics of breast cancer patients: the serum TC level was correlated with expression of progesteronereceptors (PR) and lymph node metastasis status (P<0.05), the serum TC levels of patients with negative-expression of PR and lymph node metastasis were slightly higher than that of patients with positive-expression of PR and non-lymph node metastasis; the serum TG level was associated with body mass index (P<0.05), that the serum TG level of patients with body mass index≥25 kg/m2was slightly higher than that of patients with body mass index<25 kg/m2; the serum HDL-c level was correlated with the body mass index and diameter of the tumor (P<0.05), the serum HDL-c level of the patients with body mass index≥25 kg/m2 was slightly lower than that of patients with body mass index<25 kg/m2, the serum HDL-c level of patients with the tumor diameter≤2 cm was slightly higher than that of patients with the tumor diameter >2 cm; the serum LDL-c level was correlated with body mass index, expression of estrogenreceptors (ER) and PR, and molecular typing ( P<0.05), the serum LDL-c level was slightly higher in patients with body mass index≥25 kg/m2, negative expression of ER and PR, and non Luminal type patients, comparing with patients with body mass index<25 kg/m2, positive expression of ER and PR, and Luminal type patients. Conclusions High level of serum LDL-c is strongly associated with occurrence of breast cancer, and levels of serum lipid and lipoprotein are associated with expression of hormone receptor, molecular type of breast cancer, and status of lymph node, but it needs further randomized controlled studies to confirm.
ObjectiveTo explore the correlation between lipid profile and molecular typing of invasive breast cancer.MethodsThree hundreds and seventy-five patients with primary invasive breast cancer diagnosed from Breast Surgery, Affiliated Hospital of Southwest Medical University from January 2018 to June 2019. The total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), Low-density lipoprotein cholesterol (LDL-C), apolipoprotein A (ApoA), and apolipoprotein B (ApoB) concentrations were detected. Molecular classification based on the results of postoperative immunohistochemistry of breast cancer patients, compared the measured values of each subtype.ResultsThere were no significant difference in serum TG, HDL-C and ApoA among the four subtypes (P>0.05). Differences serum levels of TC, LDL-C, and ApoB among breast cancer patients of various subtypes were statistically significant (P<0.05). Serum TC concentration in the HER2 overexpression type [(5.08±1.00) mmol/L] and the triple negative type [(5.12±0.91) mmol/L] were significantly higher than the Luminal A type [(4.68±1.01) mmol/L] and the Luminal B type [(4.79± 0.93) mmol/L], P<0.05. Serum LDL-C concentration in the triple negative type [(3.14±0.88) mmol/L] was significantly higher than the LuminalA type [(2.77±0.84) mmol/L] and the LuminalB type [(2.87±0.81) mmol/L], P<0.05. Serum ApoB concentration in the Luminal B type [(0.94±0.23) g/L] was significantly lower than the triple negative type [(1.03±0.23) g/L].ConclusionThere are differences in serum TC, LDL-C and apoB concentrations among different subtypes of breast cancer, but TG, HDL-C and ApoA are not related to molecular typing of breast cancer.

Methods In May 2007, 672 people aged from 50 to 79 years in Chengdu were recruited by random sampling methods for the survey of cardiovascular risk factors. The blood lipids level and HOMA-IR were statistically analyzed. Results ① The serum total cholesterol (TC) and high density lipoprotein chole sterol (HDL-C) were obviously higher in women than those in men (Plt;0.05). ② Triacylglycerol (TG) increased in 30.0% of men and 27.6% of women; HDL-C and low density lipoprotein cholesterin (LDL-C) in most of the involved people were appropriate. ③ HOMA-IR increased as the TG level increased and HDL-C decreased; HOMA-IR increased as the LDL-C level increased, which was significant in the females (Plt;0.05). ④ HDL-C was positively correlated with HOMA-IR (r=-0.145, P=0.000); LDL-C was positively correlated with HOMA-IR (r=0.099, P=0.010). Conclusion The increase of hypertriglyceridemia was the most frequent type of the dislipidemia in the elder people in Chengdu; HDL-C level is higher in women than in men. Dyslipidemia is correlated with insulin resistance.
ObjectivesTo systematically review the therapeutic efficacy of vitamin B1 for adjunctive treatment in type 2 diabetes mellitus.MethodsDatabases including PubMed, EMbase, The Cochrane Library, CNKI, VIP, WanFang Data and CBM were searched to collect randomized controlled trials (RCTs) on vitamin B1 for adjunctive treatment in type 2 diabetes mellitus from inception to July 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was conducted by RevMan 5.3 and Stata 12.0 softwares. ResultsA total of 6 RCTs involving 346 patients were included. The results of meta-analysis showed that, compared with the control group, the vitamin B1 adjunctive group had a significant improvement in CRP (MD=–1.09, 95%CI –1.63 to –0.54, P<0.000 1). However, the fasting blood glucose (MD=–0.23, 95%CI –0.58 to 0.13,P=0.22), glycosylated hemoglobin (MD=0.13, 95%CI –0.25 to 0.52, P=0.49), 2 hours plasma glucose (MD=–0.18, 95%CI –1.03 to 0.67, P=0.68), systolic pressure (MD=2.94, 95%CI –1.31 to 7.18, P=0.18), diastolic pressure (MD=–1.60, 95%CI –4.24 to 1.05, P=0.24), triglycerides (MD=–0.12, 95%CI –0.32 to 0.09, P=0.27), total cholesterol (MD=0.21, 95%CI –0.05 to 0.46, P=0.12), high-density lipoprotein cholesterols (MD=0.03, 95%CI –0.07 to 0.12, P=0.56) and low-density lipoprotein cholesterols (MD=0.12, 95%CI –0.11 to 0.35, P=0.30) had no significant differences between both groups.ConclusionsVitamin B1 adjunctive treatment could not improve the levels of blood glucose, blood pressure and serum lipids. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
Atherosclerotic cardiovascular disease (ASCVD) is a disease caused by the accumulation of atherosclerotic plaques that leads to arterial hardening and impairment of contractility. Proprotein convertase subtilisin/kexin type 9 (PCSK9) can increase low-density lipoprotein cholesterol levels in plasma, which accelerates the development and progression of ASCVD. This article intends to review the biological characteristics and functional mechanisms of PCSK9, elucidate its impact on the development and progression of ASCVD, provide research literature support for the diagnosis and treatment of such diseases and improving the prognosis of patients.
ObjectiveTo explore the influence factors of gallstone. MethodsClinical data of 511 patients who were admitted to our hospital from Apr. 2015 to Apr. 2016 were retrospectively analyzed. ResultsOf 511 patients, there were 274 patients with gallstone (gallstone group) and 237 patients without gallstone (control group). Univariate analysis results showed that, no significant difference of age, gender, and diabetes was found between gallstone group and control group (P > 0.050), but the levels of serum total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL-C), and fasting blood glucose (FBG) were significantly higher in patients of gallstone group (P < 0.050), but the level of serum high density lipoprotein (HDL-C) was significantly lower in patients of gallstone group (P=0.001). Logistic regression results showed that four factors including diabetes〔OR=4.491; 95% CI is (2.021, 9.976); P < 0.001〕, the serum TC〔OR=2.548; 95% CI is (1.944, 3.338); P < 0.001〕, HDL-C〔OR=0.115; 95% CI is (0.056, 0.237); P < 0.001〕, and FBG〔OR=1.277; 95% CI is (1.086, 1.502); P=0.003〕 entered the final regression model after controlling confounding factors. The results showed that patients who combined with diabetes, high levels of serum TC and FBG, and low level of serum HDL-C, had higher ratio of galls-tone. ConclusionDiabetes, high-level of serum TC and FBG, low-level of serum HDL-C were risk factors of gallstone.
Dyslipidemia plays an important role in the pathogenesis of diabetic retinopathy (DR).Apreliminary study found that low-density lipoprotein cholesterol, apolipoprotein (Apo)Band ApoB/ Apo A1 ratio were positively correlated with DR, while high-density lipoprotein cholesterol, Apo A1 was negatively correlated with DR and proliferative DR. Reducing the blood fats to be helpful to DR control. However, the mechanism of hyperlipidemia in the pathogenesis of DR, the reason of dyslipidemia in diabetic patients and the interaction between hyperglycemia and hyperlipidemia in DR are not clear yet. Moreover, there is no predictive indicators related to blood lipid for DR. Understanding the relationship between dyslipidemia and DR can provide definite evidence for fat-reducing therapy for DR control.
ObjectiveTo investigate the prevalence status and characteristics of dyslipidemia and cardiovascular risk factors in urban communities of Chengdu city. MethodsBy cluster sampling, a population of 994 inhabitants were selected from 14 urban communities in Chengdu city between February and October 2010. We investigated patients between 35-70 years old who lived in the area over 2 years, by using questionnaires survey, physical examination, and laboratory tests. According to the age, the respondents were divided into three groups: young group ( ≤ 44 years old), middle-aged group (45-59 years old) and elderly group ( ≥ 60 years old). We further investigated the major cardiovascular risk factors for hyperlipidemic patients. ResultsThe prevalence of dyslipidemia in Chengdu urban area was 28.47% (283/994), and standardized prevalence rate was 24.65% (male, 24.68%; female, 30.91%). The prevalence rate between male and female had significant diTherence (χ2=4.513, P=0.034). Female elderly group and middle-aged group had a significantly higher prevalence than the young group (P<0.05), while the male prevalence had no statistical diTherences among all age groups (P>0.05). Hypertension was most common in patients with dyslipidemia (male, 50.04%; female, 52.41%) followed by diabetes and coronary heart disease. There was no difference between male and female in the prevalence of dyslipidemia accompanied hypertension, history of stoke and coronary heart disease, abdominal obesity,or obesity (P>0.05). Higher prevalence with smoking and drinking was in male patients (P<0.05). ConclusionThe prevalence of dyslipidemia is relatively high in urban communities of Chengdu city. According to the region of hyperlipemia epidemiological characteristics and risk factors, by using comprehensive intervention measures, we can reduce the prevalence of dyslipidemia.
Objective To analyze the clinical features， common etiologies， prevention measurements of recurrent acute pancreatitis （AP）. Methods The clinical characteristics and imaging examination data of 43 patients with recurrent AP were analyzed retrospectively， which was compared with the results of 258 patients with primary AP. The recurrence etiologies were analyzed. Results There were no significant differences on the fever， jaundice， abdominal pain relief time， pancreatic local complications， and ratio of severe AP between two groups （P＞0.05）. Comparion of etiologies between recurrent AP and primary AP， cholecystitis and diet factor （alcoholic） had priority in patients with primary AP （P=0.038， P=0.006， respectively）， but the hyperlipidemic， duodenal nipple disease， and small stone in the common bile duct were the major etiologies in patients with recurrent AP （P=0.007， P=0.008， respectively）. No relapse was found within the follow up for 3 months to 2 years （the average time was 14.2 months）. Conclusion Find out the exact etiology and performe correct therapy are the key to the treatment and prevention of recurrent AP.
