OBJECTIVE:
To explore the expression regulation of lipid metabolism gene ABHD5 in testes.
METHODS:
Differential gene analysis was performed by integrating databases of TCGA and GTEx to identify the target gene ABHD5. The expression trends of ABHD5 gene in testicular carcinoma tissue were analyzed. Human testis single-cell atlases were obtained from the Human Protein Atlas and Male Health Atlas databases to determine the expression distribution of ABHD5 across different testicular cell types. Additionally, the GTEx database was utilized to visualize the expression pattern of ABHD5 in the testis, thereby enhancing the understanding of its transcriptional profile. The relationship between ABHD5 expression and age was assessed through integrated database analysis. Western blotting and immunofluorescence were performed to detect differential expressions of ABHD5 in testicular tissues of young and aged mice respectively.
RESULTS:
The TCGA database indicated that the expression of ABHD5 in human testicular carcinoma tissue was significantly lower than that in normal testicular tissue which showed a negative correlation with patient survival. ABHD5 was highly expressed in germ cells of the testis reveaked from Human Protein Atlas and Male Health Atlas databases. The stability of ABHD5 protein was crucial for testicular tissue, and its expression decreased with age. Furthermore, Western blot and immunofluorescence staining demonstrated that ABHD5 expression in the testicular tissue of aged mice was significantly lower than that in young mice.
CONCLUSION
ABHD5 plays an important role in testicular tissue, and may be inseparable from testicular tumors and reproductive aging. However, its mechanism of action remains to be further studied.

Objective:To investigate the clinical significance of TP53 allelic state in patients with myelodysplastic syndromes(MDS).Methods:The clinical data of 858 MDS patients who underwent second-generation sequencing(NGS)testing in the First Affiliated Hospital of Soochow University from January 2019 to December 2021 were retrospectively analyzed.Results:The median age of the patients was 52 years old,and median follow-up time was 23.8(0.4-109.6)months.Four hundred and one patients(46.7%)had at least one chromosomal abnormality,including 106 complex karyotypes and 78 monosomal karyotypes.A total of 103 cases of TP53 mutations were identified,with a mutation rate of 12%.Compared with TP53 wild-type,various types of chromosomal abnormalities were significantly more common in patients with TP53 mutations(all P<0.001).Patients with TP53 mutations had lower hemoglobin levels,lower platelet counts and higher percentage of bone marrow primitive cell compared with TP53 wild type(all P<0.05),and significantly shorter overall survival(OS).Among 97 evaluable patients,33 cases(34%)were mono-allelic TP53 mutation,while 64 cases were bi-allelic TP53 mutation.Patients in bi-allelic TP53 mutation subgroup had a higher proportion of chromosomal abnormalities and a lower number of co-mutations compared with mono-allelic TP53 mutation.The median OS was 33.6 months in patients with mono-allelic state and only 11.4 months in patients with bi-allelic state(HR=2.138,95%CI:1.053-4.343,P>0.05).Median OS was not reached in TP53 wild-type patients,and there was a significant difference in OS among TP53 wild-type,mono-allelic and bi-allelic TP53 mutation patients(P<0.001).Multivariable Cox regression analysis showed that bi-allelic TP53 was an independent predictor of poor outcomes(HR=2.808,95%CI:1.487-5.003,P=0.001),while mono-allelic TP53 mutation and wild-type TP53 were not.Conclusion:Patients with TP53 mutations have a poor prognosis,and bi-allelic TP53 mutations have a worse prognosis compared with mono-allelic TP53 mutations and independently affect the prognosis of MDS patients.

Background/Aims:
Oral EDP-514 is a potent core protein inhibitor of hepatitis B virus (HBV) replication, which produced a >4-log viral load reduction in HBV-infected chimeric mice with human liver cells. This study evaluated the safety, pharmacokinetics, and antiviral activity of three doses of EDP-514 in treatment-naive viremic patients with HBeAgpositive or -negative chronic HBV infection.
Methods:
Patients with HBsAg detectable at screening and at least 6 months previously were eligible. HBeAg-positive and -negative patients had a serum/plasma HBV DNA level ≥20,000 and ≥2,000 IU/mL, respectively. Twenty-five patients were randomized to EDP-514 200 (n=6), 400 (n=6) or 800 mg (n=7) or placebo (n=6) once daily for 28 days.
Results:
A dose-related increase in EDP-514 exposure (AUClast and Cmax) was observed across doses. At Day 28, mean reductions in HBV DNA were –2.9, –3.3, –3.5 and –0.2 log10 IU/mL with EDP-514 200 mg, 400 mg, 800 mg, and placebo groups, respectively. The corresponding mean change from baseline for HBV RNA levels was –2.9, –2.4, –2.0, and –0.02 log10 U/mL. No virologic failures were observed. No clinically meaningful changes from baseline were observed for HBsAg, HBeAg or HBcrAg. Nine patients reported treatment emergent adverse events of mild or moderate severity with no discontinuations, serious AEs or deaths.
Conclusions
In treatment-naïve viremic patients, oral EDP-514 was generally safe and well-tolerated, displayed PK profile supportive of once-daily dosing, and markedly reduced HBV DNA and HBV RNA.

This study aims to observe the effects of diosgenin on the expression of mammalian target of rapamycin(mTOR), sterol regulatory element-binding protein-1c(SREBP-1c), heat shock protein 60(HSP60), medium-chain acyl-CoA dehydrogenase(MCAD), and short-chain acyl-CoA dehydrogenase(SCAD) in the liver tissue of the rat model of non-alcoholic fatty liver disease(NAFLD) and explore the mechanism of diosgenin in alleviating NAFLD. Forty male SD rats were randomized into five groups: a control group, a model group, low-(150 mg·kg~(-1)·d~(-1)) and high-dose(300 mg·kg~(-1)·d~(-1)) diosgenin groups, and a simvastatin(4 mg·kg~(-1)·d~(-1)) group. The rats in the control group were fed with a normal diet, while those in the other four groups were fed with a high-fat diet. After feeding for 8 weeks, the body weight of rats in the high-fat diet groups increased significantly. After that, the rats were administrated with the corresponding dose of diosgenin or simvastatin by gavage every day for 8 weeks. The levels of triglyceride(TG), total cholesterol(TC), alanine transaminase(ALT), and aspartate transaminase(AST) in the serum were determined by the biochemical method. The levels of TG and TC in the liver were measured by the enzyme method. Oil-red O staining was employed to detect the lipid accumulation, and hematoxylin-eosin(HE) staining to detect the pathological changes in the liver tissue. The mRNA and protein levels of mTOR, SREBP-1c, HSP60, MCAD, and SCAD in the liver tissue of rats were determined by real-time fluorescence quantitative polymerase chain reaction(RT-qPCR) and Western blot, respectively. Compared with the control group, the model group showed increased body weight, food uptake, liver index, TG, TC, ALT, and AST levels in the serum, TG and TC levels in the liver, lipid deposition in the liver, obvious hepatic steatosis, up-regulated mRNA and protein expression levels of mTOR and SREBP-1c, and down-regulated mRNA and protein expression levels of HSP60, MCAD, and SCAD. Compared with the model group, the rats in each treatment group showed obviously decreased body weight, food uptake, liver index, TG, TC, ALT, and AST levels in the serum, TG and TC levels in the liver, lessened lipid deposition in the liver, ameliorated hepatic steatosis, down-regulated mRNA and protein le-vels of mTOR and SREBP-1c, and up-regulated mRNA and protein levels of HSP60, MCAD, and SCAD. The high-dose diosgenin outperformed the low-dose diosgenin and simvastatin. Diosgenin may prevent and treat NAFLD by inhibiting the expression of mTOR and SREBP-1c and promoting the expression of HSP60, MCAD, and SCAD to reduce lipid synthesis, improving mitochondrial function, and promoting fatty acid β oxidation in the liver.

Excessive sodium/salt intake is the leading dietary risk factor for the loss of healthy life in the Chinese population. The "Healthy China 2030" Action Plan set the goal of reducing salt intake by 20% by 2030. However, salt intake in China is still at a very high level in the world, with adults reaching 11 g/d, more than twice the recommended limit of 5 g/d. The current policies and action plans of China have targeted catering workers, children, adolescents, and home chefs in salt, oil, and sugar reduction actions. However, there are still obvious deficiencies in the coordinated promotion and implementation. This study, therefore, proposed a set of comprehensive strategies (named CHRPS that is composed of communication and education, salt reduction in home cooking, salt reduction in restaurants, reducing salt content in pre-packaged food, and surveillance and evaluation) and key implementation points for further deepening the salt reduction action in China. These strategies were developed based on the main sources of dietary sodium for Chinese residents, the status of "knowledge, attitude and practice" in salt reduction, evidence of effective intervention measures, existing policies and requirements, and the salt reduction strategies of the World Health Organization and experience from some other countries. As a scientific reference, the CHRPS strategies will help the government and relevant organizations quickly implement salt reduction work and facilitate the earlier realization of China's salt reduction goal.

Objective: To assess the efficacy and safety of polymyxin B in neutropenic patients with hematologic disorders who had refractory gram-negative bacterial bloodstream infection. Methods: From August 2021 to July 2022, we retrospectively analyzed neutropenic patients with refractory gram-negative bacterial bloodstream infection who were treated with polymyxin B in the Department of Hematology of the First Affiliated Hospital of the Soochow University between August 2021 to July 2022. The cumulative response rate was then computed. Results: The study included 27 neutropenic patients with refractory gram-negative bacterial bloodstream infections. Polymyxin B therapy was effective in 22 of 27 patients. The median time between the onset of fever and the delivery of polymyxin B was 3 days [interquartile range (IQR) : 2-5]. The median duration of polymyxin B treatment was 7 days (IQR: 5-11). Polymyxin B therapy had a median antipyretic time of 37 h (IQR: 32-70). The incidence of acute renal dysfunction was 14.8% (four out of 27 cases), all classified as "injury" according to RIFLE criteria. The incidence of hyperpigmentation was 59.3%. Conclusion: Polymyxin B is a viable treatment option for granulocytopenia patients with refractory gram-negative bacterial bloodstream infections.

OBJECTIVE:
To compare the curative effect of panlong needling at Jiaji (EX-B 2) combined with western medication and western medication alone on motor dysfunction in patients with Parkinson's disease (PD) of liver and kidney deficiency.
METHODS:
A total of 98 patients with PD were randomly divided into an acupuncture and medication group (49 cases, 1 case dropped off) and a western medication group (49 cases,1 case was removed). The patients in the western medication group were given oral of levodopa and benserazide hydrochloride tablets, 125 mg each time, three times a day in the 1st week, and the dose was increased according to the needs of the patients' condition from the 2nd week until 250 mg each time, three times a day, for 16 consecutive weeks. On the basis of the same western medication treatment as the western medication group, panlong needling was applied at Jiaji (EX-B 2) from C2 to L5 in the acupuncture and medication group, once a day, 20 times as a course of treatment, for 4 consecutive courses. The scores of unified Parkinson's disease rating scale (UPDRS-Ⅲ, UPDRS-Ⅳ), TCM symptoms score, and 39-item Parkinson's disease questionnaire (PDQ-39) score were evaluated before treatment, after treatment and during follow-up of 1 month after treatment, respectively. The safety of the two groups was compared.
RESULTS:
After treatment and during follow-up, except the PDQ-39 score of the western medication group, the scores of UPDRS-Ⅲ, UPDRS-Ⅳ, TCM syndrome and PDQ-39 were lower than those before treatment in the two groups (P<0.05), and the scores of above indexes in the acupuncture and medication group were lower than those of the western medication group (P<0.05). The total incidence of adverse reactions in the acupuncture and medication group was 10.4% (5/48), which was lower than 29.2% (14/48) in the western medication group (P<0.05).
CONCLUSION
Panlong needling at Jiaji (EX-B 2) combined with western medication could significantly improve the motor dysfunction and clinical symptoms, improve the quality of life and has high safety, and the efficacy is superior to western medication alone.
