Objective:To explore the prevalence, clinical features, genetic characteristics and prognosis of Citrin deficiency in Henan province of China.Methods:A total of 986 565 neonates screened by tandem mass spectrometry at the Third Affiliated Hospital of Zhengzhou University from January 2013 to December 2021 were retrospectively analyzed. Analysis of SLC25A13 gene variants and parental verification were carried out for neonates suspected for Citrin deficiency by next-generation sequencing. The clinical, biochemical and genetic characteristics of Citrin deficiency patients were integrated to guide the diet treatment and follow up the growth and development. Paired- t test was used to compare the amino acid levels in the peripheral blood samples before and after the treatment. Results:Nine cases of Citrin deficiency were diagnosed among the 986 565 neonates. Specific elevation of citrulline was observed in all of the 9 cases. Six variants were detected by genetic sequencing, among which c. 852_855delTATG, c. 615+ 5G>A, c. 550C>T and IVS16ins3kb were known pathogenic variants, whilst c. 1111_1112delAT and c. 837T>A were unreported previously. The detection rate for c. 852_855delTATG was the highest (61.6%, 11/18), followed by IVS16ins3kb (16.7%, 3/18). The clinical symptoms of all patients were relieved after the treatment, and the blood amino acid profile and biochemical parameters were significantly improved by gradually falling within the normal range. By June 2022, all patients had shown a good prognosis.Conclusion:The prevalence of Citrin deficiency among neonates from Henan Province by tandem mass spectrometry is 1/109 618, and the carrier rate for the pathogenic variants of the SLC25A13 gene was 1/166. The c. 852_855delTATG may be a hot spot variant among the patients. Discovery of the novel variants has enriched the mutational spectrum of the SLC25A13 gene. Above results have provided a basis for the early diagnosis, treatment, prognosis and genetic counseling for the affected families.

ObjectiveTo investigate the effect of modified Weijingtang on the pyroptosis of RAW264.7 macrophages via the cysteinyl aspartate-specific protease-1 (Caspase-1)/gasdermin D (GSDMD) pathway. MethodLipopolysaccharide (LPS) was used to induce pyroptosis of RAW264.7 cells. The blank group was treated with the blank serum, and the intervention groups were treated with the sera containing different doses of modified Weijingtang. After 24 h, the viability of cells in different groups was examined by the cell counting kit-8 (CCK-8). The pyroptosis and morphology of cells in each group were observed by a scanning electron microscope and a phase-contrast microscope, respectively. The mRNA and protein levels of nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3), Caspase-1, and GSDMD in each group were determined by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot, respectively. The levels of interleukin (IL)-18 and IL-1β in each group were measured by enzyme-linked immunosorbent assay. ResultUnder the electron microscope, RAW264.7 cells presented the best morphology and structure in the blank group and obvious pyroptosis and leakage of cell contents in the model (LPS) group. Compared with the model group, the intervention groups showed reduced pyroptosis to varying degrees, and the high-dose group had the closest cell morphology and structure to the blank group. Under the optical microscope, RAW264.7 cells were spherical in the blank group and irregular with protrusions in the model group. Compared with the model group, the intervention groups showed improved cell morphology, and the cell morphology in the group with the dose of 20% was the closest to that in the blank group. The mRNA and protein levels of NLRP3, Caspase-1, and GSDMD in the model group were higher than those in the blank group (P<0.05). Compared with the model group, each intervention group showed down-regulated expression of the above indicators (P<0.05). Compared with the blank group, the model group presented elevated levels of IL-18 and IL-1β (P<0.05), which were lowered in the intervention (10%, 20%) groups (P<0.01). ConclusionModified Weijingtang inhibits the pyroptosis of macrophages by down-regulating the Caspase-1/GSDMD pathway and reducing the release of proinflammatory cytokines.

Co-delivery of chemotherapeutics and immunostimulant or chemoimmunotherapy is an emerging strategy in cancer therapy. The precise control of the targeting and release of agents is critical in this methodology. This article proposes the asynchronous release of the chemotherapeutic agents and immunostimulants to realize the synergistic effect between chemotherapy and immunotherapy. To obtain a proof-of-concept, a co-delivery system was prepared

ObjectiveTo investigate the association of menopausal time and menopausal age with the risk of nonalcoholic fatty liver disease (NAFLD), and to provide a basis for the early prevention and treatment of NAFLD in clinical practice. MethodsRelated data were collected from 373 postmenopausal women who attended the outpatient service of Department of Spleen, Stomach, Liver and Gallbladder Diseases, The First Affiliated Hospital of Henan University of Chinese Medicine, from January 2017 to December 2021, including general information, menopausal age, menopausal time, and presence or absence of NAFLD. The chi-square test was used for comparison of categorical data; the independent-samples t test was used for comparison of normally distributed continuous data between groups, and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between groups. A Logistic regression analysis was used to calculate the association intensity and 95% confidence interval (95%CI) of menopausal time and menopausal age for the risk of NAFLD, and the restricted cubic spline (RCS) method was used to investigate the dose-response relationship between menopausal time/age and the risk of NAFLD. ResultsCompared with the women with normal menopause or late menopause, the women with early menopause had a higher prevalence rate of NAFLD and a higher degree of steatosis and fibrosis (all P<0.05). After adjustment for the confounding factors such as age and age of menarche, the risk of NAFLD in women with a menopausal time of >3 years was 4.80 (95%CI: 1.93 — 11.95, P=0.001) times that in women with a menopausal time of ≤3 years, and the risk of NAFLD in women with early or late menopause was 8.14 times (95%CI: 1.77 — 37.58, P=0.007) and 0.09 times (95%CI: 0.03 — 0.32, P<0.001), respectively, that in those with a normal menopausal age. There is a dose-response relationship between menopausal time/age and the risk of NAFLD. Menopausal time is positively correlated with the association intensity of NAFLD, while menopausal age is negatively correlated with the association intensity of NAFLD. ConclusionThe longer the menopause time and the earlier the menopause age, the ligher the risk of NAFLD.

【Objective】 To compare the ability of body mass index (BMI), body fat percentage (BFP), waist circumference (WC), waist-to-height ratio (WHtR), visceral fat index (VFI) and the combinations of two kinds of obesity indices to predict the risk of hypertension. 【Methods】 Data collected in the baseline survey of “Gansu Province’s Urban and Rural Natural Population Cohort Establishment and Tumor Follow-up Study” were analyzed. Area under the curve (AUC) of ROC curve with covariates was used to analyze and compare the effects of individual obesity evaluation index and the combination of two kinds of obesity indices in predicting the risk of hypertension. 【Results】 Analyses of data of 20,079 adults showed that the AUC of BMI, WC, WHtR, BFP and VFI was 0.636, 0.604, 0.615, 0.614 and 0.619, respectively. AUC of the combination of BMI and WC (0.643) was higher than that of BMI (0.636); however, the change rate of AUC was only 1.09%. AUC of the combinations of WC, WHtR and VFI, the three central obesity evaluation indices, and BFP, a general obesity evaluation index, were lower than that of BMI. The optimal cutoff value for BMI was 24.2 kg/m2. 【Conclusion】 The effect of BMI in predicting the risk of hypertension is better than that of BFP, WC, WHtR and VFI. The effects of the combinations of the two kinds of obesity evaluation indices are not better than that of BMI. To prevent and control hypertension, adults should keep their BMI under overweight.
