Objective To analyze the follow-up results and clinical characteristics of one case of highly sensitized recipient after combined kidney transplantation and splenic fossa auxiliary heterotopic liver transplantation.Methods This patient was diagnosed as having chronic renal insufficiency in the uremia period 10 years ago,subjected to kidney transplantation 9 years ago,and got renal allograft loss 8 years ago.The recipient was positive for PRA (for class Ⅰ,31%,and for class Ⅱ,63%).Under the general anesthesia,the patient was given combined kidney transplantation and splenic fossa auxiliary heterotopic liver transplantation.The ATG was used for immune induction.Rituximab and plasma exchange were applied to prevent acute rejection.Regular follow-up was done after discharge.Results On the postoperative day (POD) one,ALT was 256 IU/L,AST was 342 IU/L and serum creatinine was 502 μmol/L.On the POD 6,ALT and AST levels were normal and serum creatinine was 141 μmol/L.Serum creatinine increased to 202 μmol/L and the volume of urine reduced on the POD 7.The ultrasound displayed graft size increased slightly,substantial echogenicity enhanced,artery blood flow RI increased to 0.8,suggesting the occurrence of acute rejection.A single dose of Rituximab,intravenous IG,and plasma exchange were given.On the POD 60,serum creatinine was reduced to 131 μmol/L.During a follow-up period of 28 months,imrnunosuppresants were given:Tac + MMF + Pred.FK506 valley concentration was maintained at 6-8 μg/L.The function of the transplanted kidney and liver was normal,and the general conditions were good.Conclusion Combined kidney transplantation and splenic fossa auxiliary heterotopic liver transplantation is safe.Individualized medication and regular follow-up are the important factors for long-term survival of recipients.

Angiostrongylus cantonensis invades the central nervous system (CNS) of humans to induce eosinophilic meningitis and meningoencephalitis and leads to persistent headache, cognitive dysfunction, and ataxic gait. Infected mice (nonpermissive host), admittedly, suffer more serious pathological injuries than rats (permissive host). However, the pathological basis of these manifestations is incompletely elucidated. In this study, the behavioral test, histological and immunohistochemical techniques, and analysis of apoptotic gene expression, especially caspase-3, were conducted. The movement and motor coordination were investigated at week 2 post infection (PI) and week 3 PI in mice and rats, respectively. The cognitive impairs could be found in mice at week 2 PI but not in rats. The plaque-like lesion, perivascular cuffing of inflammatory cells, and dilated vessels within the cerebral cortex and hippocampus were more serious in mice than in rats at week 3 PI. Transcriptomic analysis showed activated extrinsic apoptotic pathway through increased expression of TNFR1 and caspase-8 in mice CNS. Immunohistochemical and double-labeling for NeuN and caspase-3 indicated the dramatically increased expression of caspase-3 in neuron of the cerebral cortex and hippocampus in mice but not in rats. Furthermore, western-blotting results showed high expression of cleaved caspase-3 proteins in mice but relatively low expression in rats. Thus, extrinsic apoptotic pathway participated in neuronal apoptosis might be the pathological basis of distinct behavioral dysfunctions in rodents with A. cantonensis infection. It provides the evidences of a primary molecular mechanism for the behavioral dysfunction and paves the ways to clinical diagnosis and therapy for A. cantonensis infection.

Objective:To evaluate the post-marketing safety and immunogenicity of a 23-valent pneumococcal polysaccharide vaccine (PPV23).Methods:From September 2020 to June 2021, a clinical trial of single-dose PPV23 was conducted in people ≥3 years old in Centers for Disease Control and Prevention of Guizhou, Hunan and Fujian provinces. Blood samples were collects from the subjects before and 30 d after vaccination. ELISA was used to quantitatively detect IgG antibodies against capsular polysaccharides of 23 Streptococcus pneumoniae serotypes in serum samples. The adverse events (AEs) were monitored within 7 d after vaccination. Results:A total of 409 subjects were enrolled and included in safety analysis. Except for one with antibody level inversion, the other 408 participants were included in immunogenicity analysis. The levels of antibodies against the 23 Streptococcus pneumoniae serotypes were all increased after vaccination by an average of 4.24 folds. The two-fold growth rates of the antibodies ranged from 51.72% to 96.81% with a total two-fold growth rate of 78.59%. The overall rate of AEs was 27.14% (111/409). Local AEs were mainly pain, induration, redness and swollen. No serious adverse events related to vaccination occurred. Conclusions:This study preliminarily demonstrated the good immunogenicity and safety of PPV23 vaccine.

The complexity of oral ulcerations poses considerable diagnostic and therapeutic challenges to oral specialists. The expert consensus was conducted to summarize the diagnostic work-up for difficult and complicated oral ulcers, based on factors such as detailed clinical medical history inquiry, histopathological examination, and ulceration-related systemic diseases screening. Not only it can provide a standardized procedure of oral ulceration, but also it can improve the diagnostic efficiency, in order to avoid misdiagnosis and missed diagnosis.
