Background/Aims: The World Health Organization set the goal of eliminating hepatitis C virus (HCV) by 2030, with 80% and 65% reductions in HCV incidence and mortality rates, respectively. We aimed to evaluate the health benefits, cost-effectiveness and return on investment (ROI) of HCV elimination. Methods: Using an HCV transmission compartmental model, we evaluated the benefits and costs of different strategies combining screening and treatment for Chinese populations. We identified strategies to achieve HCV elimination and calculated the incremental cost-effectiveness ratios (ICERs) per disability-adjusted life year (DALY) averted for 2022–2030 to identify the optimal elimination strategy. Furthermore, we estimated the ROI by 2050 by comparing the required investment with the economic productivity gains from reduced HCV incidence and deaths. Results: The strategy that results in the most significant health benefits involves conducting annual primary screening at a rate of 14%, re-screening people who inject drugs annually and the general population every five years, and treating 95% of those diagnosed (P14-R4-T95), preventing approximately 5.75 and 0.44 million HCV infections and deaths, respectively, during 2022–2030. At a willingness-to-pay threshold of $12,615, the P14-R4-T95 strategy is the most cost-effective, with an ICER of $5,449/DALY. By 2050, this strategy would have a net benefit of $120,997 million (ROI=0.868). Conclusions Achieving HCV elimination in China by 2030 will require significant investment in large-scale universal screening and treatment, but it will yield substantial health and economic benefits and is cost-effective.

This paper summarizes Professor WANG Xiuxia's clinical experience in treating hyperprolactinemia using the liver soothing therapy. Professor WANG identifies liver qi stagnation and rebellious chong qi （冲气） as the core pathomechanisms of hyperprolactinemia. Furthermore， liver qi stagnation may transform into fire or lead to pathological changes such as spleen deficiency with phlegm obstruction or kidney deficiency with essence depletion. The treatment strategy centers on soothing the liver， with a modified version of Qinggan Jieyu Decoction （清肝解郁汤） as the base formula. Depending on different syndrome patterns such as liver stagnation transforming into fire， liver stagnation with spleen deficiency， or liver stagnation with kidney deficiency， heat clearing， spleen strengthening， or kidney tonifying herbs are added accordingly. In addition， three paired herb combinations are commonly used for symptom specific treatment， Danggui （Angelica sinensis） with Chuanxiong （Ligusticum chuanxiong）， Zelan （Lycopus lucidus） with Yimucao （Leonurus japonicus） ， and Jiegeng （Platycodon grandiflorus） with Zisu （Perilla frutescens）.

Increasing evidence shows that the early lesions of Parkinson's disease (PD) originate from gut, and correction of microbiota dysbiosis is a promising therapy for PD. FLZ is a neuroprotective agent on PD, which has been validated capable of alleviating microbiota dysbiosis in PD mice. However, the detailed mechanisms still need elucidated. Through metabolomics and 16S rRNA analysis, we identified glycoursodeoxycholic acid (GUDCA) was the most affected differential microbial metabolite by FLZ treatment, which was specially and negatively regulated by Clostridium innocuum, a differential microbiota with the strongest correlation to GUDCA production, through inhibiting bile salt hydrolase (BSH) enzyme. The protection of GUDCA on colon and brain were also clarified in PD models, showing that it could activate Nrf2 pathway, further validating that FLZ protected dopaminergic neurons through promoting GUDCA production. Our study uncovered that FLZ improved PD through microbiota-gut-brain axis, and also gave insights into modulation of microbial metabolites may serve as an important strategy for treating PD.

Although enteric glial cell (EGC) abnormal activation is reported to be involved in the pathogenesis of Parkinson's disease (PD), and inhibition of EGC gliosis alleviated gut and dopaminergic neuronal dysfunction was verified in our previous study, the potential role of gut microbiota on EGC function in PD still need to be addressed. In the present study, fecal microbiota transplantation revealed that EGC function was regulated by gut microbiota. By employing 16S rRNA and metabolomic analysis, we identified that 3-indolepropionic acid (IPA) was the most affected differential microbial metabolite that regulated EGC gliosis. The protective effects of IPA on PD were validated in rotenone-stimulated EGCs and rotenone (30 mg/kg i.g. for 4 weeks)-induced PD mice, as indicated by decreased inflammation, improved intestinal and brain barrier as well as dopaminergic neuronal function. Mechanistic study showed that IPA targeted pregnane X receptor (PXR) in EGCs, and inhibition of IL-13Rα1 involved cytokine-cytokine receptor interaction pathway, leading to inactivation of downstream JAK1-STAT6 pathway. Our data not only provided evidence that EGC gliosis was critical in spreading intestinal damage to brain, but also highlighted the potential role of microbial metabolite IPA in alleviating PD pathological damages through gut-brain axis.

The sternum is the pivotal component of the thoracic cavity. It is connected with the clavicle and ribs on the upper part and both sides respectively, and plays an important role in protecting the stability of the chest wall. Sternal resection usually results in a large segmental chest wall defect that causes the chest wall to float and requires sternal reconstruction. This paper reports a 62 years male patient with thymic squamous cell carcinoma with sternal metastasis, who underwent thymotomy, sternal tumor resection and autologous lilum graft combined with sternal reconstruction by titanium plate after relevant examination was completed and surgical contraindications were eliminated. The patient was followed up for 6 months, the respiratory and motor functions were normal and the thoracic appearance was good.

Objective The imaging findings of X-ray defecography(XRD)and magnetic resonance defecog-raphy(MRD)of patients with Solitary Rectal Ulcer syndrome(SRUS)were retrospectively analyzed to provide important information for clinical diagnosis and treatment.Methods 19 patients with SRUS confirmed by clinical,pathological and colonoscopy were included in this study.Among them,15 patients underwent XRD and 7 patients underwent MRD,and 3 patients underwent both XRD and MRD.Data of all enrolled patients were collected and pelvic floor function was measured.Results In the results of XRD,3 patients(20%)showed rectal intussusception.8 patients(53.3%)showed external rectal prolapse and 2 patients(13.3%)showed moderate rectocele.In addition,there were 2 patients of puborectal muscle hypertrophy,and 1 patient of bladder prolapse and uterine prolapse,respectively.For MRD,3 patients(42.9%)showed rectal mucosal prolapse(partial prolapse).At 4 patients(57.1%)with rectocele,3 patients(all female)had moderate rectocele,1 patient had mild rectocele.3 patients were also observed related anterior and middle compartment organ descent.2 patients of pubulorectal muscle hypertrophy,no sigmoidocoele.Conclusion Defecography can evaluate the structural and functional abnormalities of pelvic floor in SRUS patients,such as external rectal prolapse,rectal protrusion,rectal mucosal prolapse,and rectal intussusception,which has guiding significance for the treatment of SRUS patients.

Objective To use metabolomics method to study the metabolic profiles of amino acids and lysophosphatidylcholine(LPC)in the serum of rats with nonalcoholic fatty liver disease(NAFLD),to identify biomarkers for NAFLD,and to speculate on the possible mechanism responsible for its occurrence.Methods NAFLD rats were prepared by feeding a high-fat diet and intraperitoneal injection of carbon tetrachloride.Levels of 15 LPCs and 18 amino acids in the serum were determined in control and NAFLD rats by liquid chromatography-mass spectrometry.Changes in serum LPC and amino acid metabolic profiles in NAFLD rats were analyzed by principal component analysis and orthogonal partial least squares discriminant analysis.Correlations between biomarkers and NAFLD were analyzed by Pearson's correlation analysis.Results The metabolic profiles of serum LPC and amino acids differed significantly between the NAFLD group and the control group and were completely distinct.LPC(20∶1),arginine,and glutamic acid had significant contributions to NAFLD and were identified as biomarkers.Furthermore,LPC(20∶1)and arginine were significantly correlated with serum biochemical indicators such as aspartate transaminase,alanine transaminase,low-density lipoprotein,and total bilirubin.Conclusions The metabolic profiles of serum LPC and amino acids may be closely related to NALFD.
