PurposeTo observe the effects of blocking the renin-Angiotensin-Aldosterone system at different sites in experimental congestive heart failure (CHF)rats. Methods Six weeks after coronary ligation, rats( n = 66)were randomized to benalapril, losartan, spironolactone, placebo, and treated for 6 weeks. Sham-operated rats( n = 18) served as controls. Six weeks later left ventricular hemodynamics were measured. Results In the hemodynamic variables, HR was not significantly different between groups. Compared four treatment groups with sham-operated group, LVEDP increased, LVPSP and ± dp/dtmax decreased (P<0.05). Compared with placebo group,all data in spironolactone group were not significantly different, LVEDP, mortality in benalapril group and in losartan group decreased, LVPSP and ± dp/dtmax in benalapril group and in losartan group increased(P < 0.05). ConclusionsAdministration of ACEI and Ag Ⅱ-AT1 antagonist are effective in preventing from cardiac function deterioration, while spironolactone treatments are not. Spironolactone has tendency in decreasing LVEDP.

Objective To study clinically the feasibility of early diagnosis of cardiac allograft vascularopathy (CAV) and chronic rejection. Methods A 13 year old female patient with dilated cardiomyopathy received orthotopic heart transplantation for advanced heart failure, and subsequent immunosuppressive therapy including cyclosporine, prednisone and mofetil, and a monthly close follow up. Coronary angiography and left ventricular endomyocardial biopsy (EMB) was performed 9 months after the operation. Results The clinical and follow up data of the case showed that cardiac or systemic nonspecific symptoms such as exertional chest discomfort, palpitation, fatigue or fever of unknown reasons were the first and ignorable clinical symptoms, and found disappeared after dosage addition of cyclinsporine, which indicated a early clinical manifestations of rejection or vasculopathy. While persistent sinus tachycardia on electrocardiogram, decreased left ventricular ejection fraction (from 64?% ~68?% down to 47?%~50?%), enlarged right atrial (from 32~ 41?mm up to 44?mm in diameter), thickened intraventricular septal ( 13?mm ), repetitive tricuspid regurgitation on echocardiography, increased white blood cells without infection were observed respectively. Coronary angiography showed a typical (type B) vasculopathy with diffuse concentric stenosis of mid and distal left anterior descending artery and its small braches, the distal diagonal, circumflex, and right coronary artery were also involved to some extent. Furthermore, early mild chronic rejection of grade I A was proved by pathologic study. Conclusion Close clinical observation and follow up, serial echocardiography and electrocardiogram, reaction to enhanced anti rejection, and other related laboratory methods could be analyzed and colligated for early noninvasive diagnosis of cardiac allograft vasculopathy and chronic rejection, while EMB and coronary angiography are still the precise diagnostic ways.

Objective:
To explore the association between processed food consumption and anxiety symptoms among college students in Yunnan Province, so as to provide a reference for the prevention and treatment of anxiety symptoms in this population.
Methods:
A cluster random sample of 2 515 first year students from two universities in Yunnan Province was selected to carry out a longitudinal investigation which included a baseline survey (November 2021, T1) and three follow up visits (June 2022, T2; November 2022, T3; June 2023, T4). The food frequency questionnaire was administered to assess processed food consumption, and the Depression Anxiety Stress Scale-21 (DASS-21, Chinese version) was used to evaluate anxiety symptoms. A generalized estimation equation model was used to analyze the relationship between processed food consumption and anxiety symptoms.
Results:
The detection rates of T1-T4 anxiety symptoms among college students in Yunnan Province were 29.70%, 36.70%, 37.69% and 38.73 %, respectively, and the corresponding anxiety symptom scores were 4(0,8), 4(0,10), 4(0,12), 2(0,14). After controlling for demographic variables and confounding factors in the generalized estimation equation model, a statistically significant association was found between consumption of carbonated beverages ( β=0.06, 95%CI =0.03-0.08), and other processed snacks ( β= 0.04 , 95%CI =0.01-0.07) ( P <0.05). The stratified analysis by gender showed that the consumption of carbonated beverages ( β=0.08, 95%CI =0.05-0.12) and fast food ( β=0.03, 95%CI =0.00-0.06) was significantly associated with anxiety symptoms in female college students ( P <0.05). There was no significant association between processed food consumption and anxiety symptoms in male college students ( P >0.05).
Conclusions
Processed food consumption by college students in Yunnan Province may increase the risk of anxiety symptoms, particularly among female students. There is a need to strengthen guidance in respect to processed food consumption, so as to prevent and treat anxiety symptoms.

OBJECTIVE:
To analyze gene variants in a Chinese pedigree with oculocutaneous albinism (OCA).
METHODS:
Gene sequencing of the proband and his parents was performed using chip capture high-throughput sequencing and Sanger sequencing techniques, and PolyPhen-2, SIFT, MutationTaster, and FATHMM software were used to predict the function of new variants. At the same time,the pedigree and variant genes of 4 albinism patients from this pedigree were analyzed.
RESULTS:
Sequencing results showed that the proband's TYR gene (NM_000372) has c.230G>A (p.Arg77Gln) and c.120_121insG (p.Asp42GlyfsTer35) compound heterozygous variants. The proband's father carries c.230G>A heterozygous variant, and the mother carries c.120_121insG heterozygous variant, indicating that the proband's two variants are from his father and mother. The former is a known missense variant, which can cause abnormal or loss of the original function of the protein polypeptide chain. The latter c.120_121insG(p.Asp42GlyfsTer35) is an unreported frameshift variant of the TYR gene subregion (EX1; CDS1). PolyPhen-2, SIFT, MutationTaster and FATHMM predictions are all prompted as "harmful variants". This variant caused the amino acid encoded protein to terminate prematurely, producing a truncated protein, which eventually formed a 76-amino acid short-type TYR protein instead of the 529-amino acid wild-type TYR protein. Through the pedigree analysis, the four patients in the pedigree are all of the same type of compound heterozygous variants, and the disease-causing genes are all from the patient's parents. They belong to a special form of consanguineous marriage within 5 generations.
CONCLUSION
The compound heterozygous variants of c.230G>A (p.Arg77Gln) and c.120_121insG (p.Asp42GlyfsTer35) of the TYR gene may underlie the disease in this pedigree. The gene sequencing results enrich the variant spectrum of the TYR gene, and has facilitated molecular diagnosis for the patient.

Hepatocellular carcinoma has a low early diagnostic rate, and there is a lack of highly sensitive and specific tumor markers. In recent years, fluid biopsy technique, represented by circulating free DNA (cfDNA), has become an auxiliary method for the diagnosis of cancer and has attracted more and more attention due to its advantages of noninvasiveness, convenience, and repeatability. With reference to the recent studies in China and foreign countries, this article summarizes and analyzes the advances in cfDNA in the diagnosis and treatment of hepatocellular carcinoma from the aspects of biological characteristics, detection techniques, and clinical application, so as to provide a basis for clinical diagnosis and treatment.
