ObjectiveTo investigate the clinical features and outcomes of recompensation in patients with autoimmune hepatitis （AIH）-related decompensated cirrhosis， to identify independent predictive factors， and to construct a nomogram prediction model for the probability of recompensation. MethodsA retrospective cohort study was conducted among the adult patients with AIH-related decompensated cirrhosis who were admitted to The Fifth Medical Center of PLA General Hospital from January 2015 to August 2023 （n=211）. The primary endpoint was achievement of recompensation， and the secondary endpoint was liver-related death or liver transplantation. According to the outcome of the patients at the end of the follow-up， the patients were divided into the recompensation group （n=16） and the persistent decompensation group（n=150）.The independent-samples t test was used for comparison of normally distributed continuous data with homogeneity of variance， and the Mann-Whitney U rank sum test was used for comparison of non-normally distributed continuous data with heterogeneity of variance； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups； the Kaplan-Meier method was used for survival analysis； the Cox proportional-hazards regression model was used to identify independent predictive factors， and a nomogram model was constructed and validated. ResultsA total of 211 patients were enrolled， with a median age of 55.0 years and a median follow-up time of 44.0 months， and female patients accounted for 87.2%. Among the 211 patients， 61 （with a cumulative proportion of 35.5%） achieved recompensation. Compared with the persistent decompensation group， the recompensation group had significantly higher white blood cell count， platelet count （PLT）， total bilirubin （TBil）， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， total bile acid， prothrombin time， international normalized ratio （INR）， SMA positive rate， Model for End-Stage Liver Disease （MELD） score， Child-Pugh score， and rate of use of glucocorticoids （all P0.05）， as well as significantly lower age at baseline， number of complications， and death/liver transplantation rate （all P0.05）. At 3 and 12 months after treatment， the recompensation group had continuous improvements in AST， TBil， INR， IgG， MELD score， and Child-Pugh score， which were significantly lower than the values in the persistent decompensation group （all P0.05）， alongside with continuous increases in PLT and albumin， which were significantly higher than the values in the persistent decompensation group （P0.05）. The multivariate Cox regression analysis showed that baseline ALT （hazard ratio ［HR］=1.067， 95% confidence interval ［CI］： 1.010 — 1.127， P=0.021）， IgG （HR=0.463，95%CI：0.258 — 0.833， P=0.010）， SMA positivity （HR=3.122，95%CI：1.768 — 5.515， P0.001）， and glucocorticoid therapy （HR=20.651，95%CI：8.744 — 48.770， P0.001） were independent predictive factors for recompensation， and the nomogram model based on these predictive factors showed excellent predictive performance （C-index=0.87，95%CI：0.84 — 0.90）. ConclusionAchieving recompensation significantly improves clinical outcomes in patients with AIH-related decompensated cirrhosis. Baseline SMA positivity， a high level of ALT， a low level of IgG， and corticosteroid therapy are independent predictive factors for recompensation. The predictive model constructed based on these factors can provide a basis for decision-making in individualized clinical management.

Objective:To examine the effects of Zishenwan Prescription on bile acid metabolism in mice with diabetic encephalopathy; To explore its mechanism of improvement of diabetic encephalopathy.Methods:Male C57BL/6J mice were used to replicate the mouse model of type 2 diabetes mellitus by using high-fat chow and a single intraperitoneal injection of streptozotocin (120 mg/kg). The mice were screened for diabetic encephalopathy by using the Morris water maze test after 8 weeks of continuous stimulation with hyperglycemia, and were divided into model group and Zishenwan Prescription group according to random number table method, with 12 mice in each group. The mice in the Zishenwan Prescription group were treated with the crude extract of Zishenwan Prescription (9.36 g/kg) by gavage, and the normal group and the model group were treated with the same volume of distilled water once a day for 8 weeks. At the end of the treatment, Morris water maze test was used to investigate the cognitive function of diabetic encephalopathy mice; cresyl violet staining was used to detect the number of granule neurons in the hippocampus; serum and feces were collected to detect the content of bile acids by liquid-liquid coupling; hepatic bile acid synthase CYP7a1 and CYP27a1, farnesol X receptor (FXR), fibroblast growth factor 15 (FGF15), fibroblast growth factor receptor 4 (FGFR4), and ileocecal apical sodium-dependent bile acid transporter protein (ABST) mRNA levels were detected by using fluorescence quantitative PCR assay.Results:Compared with the model group, mice in the Zishenwan Prescription group had shorter evasion latency time ( P<0.05 or P<0.01), decreased time to first reach the platform ( P<0.01), increased number of times to traverse the platform ( P<0.01), and reduced neuronal cell damage in hippocampal area; mice in the Zishenwan Prescription group showed decreased serum and fecal total bile acid content ( P<0.05 or P<0.01); the liver CYP7a1 and CYP27a1 mRNA expressions increased ( P<0.01), and FXR and FGF15 mRNA expressions decreased ( P<0.01); ileal ABST mRNA expression decreased ( P<0.01). Conclusion:Zishenwan Prescription may regulate bile acid metabolism, inhibit FRX-FGF15/FGFR4 signaling and ABST expression to promote new bile acid synthesis and conjugated bile acid reabsorption, and thus improve cognitive function in diabetic encephalopathy mice.

Objective To investigate the peripheral retinal defocus and its influencing factors in children and adoles-cents with low to moderate myopia.Methods Totally 281 children and adolescents aged 6-15 years were included in the study,and only the right eye was selected.After cycloplegic refraction as well as axial length(AL)and average corneal curvature(AveK)measurements,the patients were divided into low myopia(LM)group(-3.00 D≤SE≤-0.50 D)and moderate myopia(MM)group(-6.00 D≤SE＜-3.00D)according to spherical equivalent(SE),and stratified compari-sons were made according to AL[AL1 group(23.00 mm≤AL≤24.00 mm),AL2 group(24.00 mm＜AL≤25.00 mm),and AL3 group(25.00 mm＜AL≤26.00 mm)]and AveK[AveK1 group(40.00 D≤ Ave K≤43.00 D)and AveK2 group(43.00 D＜AveK≤46.00 D)].Multispectral refraction tomography was used to measure the refraction difference value(RDV),in-cluding TRDV(0° to 53°),RDV-15(0° to 15°),RDV-30(0° to 30°),RDV-45(0° to 45°),RDV-15-30(15° to 30°),RDV-30-45(30° to 45°),RDV-45-53(45° to 53°),RDV-S(superior),RDV-I(inferior),RDV-T(temporal)and RDV-N(na-sal).The RDV was compared in the groups divided according to SE,AL and AveK individually,and the correlation be-tween RDV and age,SE,AL and AveK was analyzed.Moreover,the factors affecting RDV in all ranges were analyzed by multiple linear regression.Results Compared with the LM group,the MM group had significant increases in TRDV,RDV-30,RDV-45,RDV-15-30,RDV-30-45,RDV-45-53,RDV-S,RDV-I and RDV-N(all P＜0.05)and no significant differ-ence in RDV-15 and RDV-T(both P＞0.05).According to the comparisons of AL groups and AveK groups,the TRDV,RDV-30,RDV-45,RDV-15-30,RDV-30-45,RDV-45-53,RDV-S,RDV-I and RDV-N in the AL2 group were significantly higher than those in the AL1 group(all P＜0.05);the TRDV,RDV-30,RDV-45,RDV-15-30,RDV-30-45,RDV-45-53,RDV-S and RDV-N in the AL3 group were significantly higher than those in AL2 and AL1 groups,and RDV-I and RDV-T in the AL3 group were significantly higher than those in the AL1 group(both P＜0.05);the TRDV,RDV-30,RDV-45,RDV-15-30,RDV-30-45,RDV-45-53,RDV-S,and RDV-I in the Ave K1 group were significantly higher than those in the AveK2 group(all P＜0.05).The correlation analysis showed that TRDV,RDV-45,RDV-30-45,RDV-45-53,RDV-S and RDV-N were positively correlated with age and AL and negatively correlated with SE and Ave K;RDV-30,RDV-15-30 and RDV-I were positively cor-related with AL and negatively correlated with SE and AveK;RDV-T was positively correlated only with AL;RDV-15 was not correlated with age,SE,AL and AveK.Multiple linear regression analysis showed that age was the influencing factor of RDV-45-53 and RDV-S;AL was the influencing factor of TRDV,RDV-30,RDV-45,RDV-15-30,RDV-30-45,RDV-45-53,RDV-S and RDV-T;AveK was the influential factor of RDV-I;SE had no significant effect on RDV in all ranges.Conclu-sion Peripheral retinal defocus in children and adolescents with low to moderate myopia has reached hyperopic defocus,and hyperopic defocus is the least in patients with relatively short AL.Age,AL and AveK can affect peripheral retinal defo-cus in children and adolescents with low to moderate myopia,among which AL is the most important influencing factor.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).

Cognitive dysfunction is one of the common central nervous systems (CNS) complications of diabetes mellitus, which seriously affects the quality of life of patients and results in a huge economic burden. The glymphatic system dysfunction mediated by aquaporin-4 (AQP4) loss or redistribution in perivascular astrocyte endfeet plays a crucial role in diabetes-induced cognitive impairment (DCI). However, the mechanism of AQP4 loss or redistribution in the diabetic states remains unclear. Accumulating evidence suggests that peripheral insulin resistance target tissues and CNS communication affect brain homeostasis and that exosomal miRNAs are key mediators. Glucose and lipid metabolism disorder is an important pathological feature of diabetes mellitus, and skeletal muscle, liver and adipose tissue are the key target insulin resistance organs. In this review, the changes in exosomal miRNAs induced by peripheral metabolism disorders in diabetes mellitus were systematically reviewed. We focused on exosomal miRNAs that could induce low AQP4 expression and redistribution in perivascular astrocyte endfeet, which could provide an interorgan communication pathway to illustrate the pathogenesis of DCI. Furthermore, the mechanisms of exosome secretion from peripheral insulin resistance target tissue and absorption to the CNS were summarized, which will be beneficial for proposing novel and feasible strategies to optimize DCI prevention and/or treatment in diabetic patients.

ObjectiveTo observe the effect of the Fangfeng Tongshengsan on post-chemoembolization syndrome with primary liver cancer or postoperative liver metastases of colorectal cancer. MethodSeventy-two patients suffered from post-chemoembolization syndrome after transcatheter hepatic arterial chemoembolization were randomly divided into 2 groups， including a Fangfeng Tongshengsan group and a control group， with 36 patients in each group. The patients in Fangfeng Tongshengsan group orally took the decoction for consecutive 7 d. The patients in the control group were physically cooled down with alcohol rub bath and ice pack for consecutive 7 d. Furthermore， the difference of fever， Karnofsky performance status （KPS）， pain in the liver region， nausea vomiting， constipation， and liver function between these two groups were observed. ResultCompared with the control group， Fangfeng Tongshengsan significantly relieved fever， reduced the body temperature （P<0.05）， and shortened the duration of fever （P<0.05）， indicating that Fangfeng Tongshengsan remarkably improved the KPS （P<0.05）. Meanwhile， Fangfeng Tongshengsan obviously alleviated nausea， vomiting， and constipation status and shortened the duration time compared with the control group （P<0.05）. In addition， the parameters of liver function including alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， γ-glutamyl transpeptidase （GGT）， and total bilirubin （TBIL） were significantly decreased in the Fangfeng Tongshengsan group （P<0.05）， which indicated that Fangfeng Tongshengsan alleviated liver dysfunction of patients with post-chemoembolization syndrome. ConclusionFangfeng Tongshengsan can be used to treat post-chemoembolization syndrome with primary liver cancer and postoperative liver metastases of colorectal cancer.

Objective     To investigate the influence of prior percutaneous coronary intervention (PCI) on the outcome of coronary artery bypass grafting (CABG). Methods     Clinical data of 5 216 patients from Jiangsu Province CABG registry who underwent primary isolated CABG from 2016 to 2019 were retrospectively analyzed. Patients were divided into a PCI group (n=673) and a non-PCI group (n=4 543) according to whether they had received PCI treatment. The PCI group included 491 males and 182 females, aged 62.6±8.2 years, and the non-PCI group included 3 335 males and 1 208 females, aged 63.7±8.7 years. Multivariable logistic regression and propensity score matching (PSM) were used to compare 30-day mortality, incidence of major complications and 1-year follow-up outcomes between the two groups. Results     Both in original cohort and matched cohort, there was no statistical difference in the 30-day mortality [14 (2.1%) vs. 77 (1.7%), P=0.579; 14 (2.1%) vs. 11 (1.6%), P=0.686], or the incidence of major complications (myocardial infarction, stroke, mechanical ventilation≥24 h, dialysis for new-onset renal failure, deep sternal wound infection and atrial fibrillation) (all P>0.05). The rate of reoperation for bleeding in the PCI group was higher than that in the non-PCI group [19 (2.8%) vs. 67 (1.5%), P=0.016; 19 (2.8%) vs. 7 (1.0%), P=0.029]. Both in original cohort and matched cohort, there was no statistical difference in 1-year survival rate between the two groups [613 (93.1%) vs. 4 225 (94.6%), P=0.119; 613 (93.1%) vs. 630 (95.2%), P=0.124], while the re-admission rate in the PCI group was significantly higher than that in the non-PCI group [32 (4.9%) vs. 113 (2.5%), P=0.001; 32 (4.9%) vs. 17 (2.6%), P=0.040]. Conclusion     This study shows that a history of PCI treatment does not significantly increase the perioperative mortality and major complications of CABG, but increases the rate of cardiogenic re-admission 1 year postoperatively.

Along with the increasingly serious environmental pollution, dealing with the "white pollution" issue, which is caused by the worldwide use of not readily-degradable or non-degradable synthetic plastics, has become a great challenge. It is an environmentally friendly strategy to degrade synthetic plastics using microorganisms that exist in nature or evolved under selection pressure. Based on the NSFC-EU International Cooperation and Exchanges Project "Bio Innovation of a Circular Economy for Plastics", this review summarized the screening of bacteria, fungi and microbial consortia capable of degrading synthetic plastics such as polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), polyurethane (PUR), and polyethylene terephthalate (PET). We also analyzed the role of various microorganisms played in the degradation of petroleum-based plastics. Moreover, we discussed the pros and cons of using microorganisms and enzymes for degradation of synthetic plastics.

【Objective】 To retrospectively analyze the irregular antibodies in 6 blood group systems other than the Rh blood group system in 53 pregnant women and analyze its correlation with the occurrence of hemolytic disease of the newborn(HDN). 【Methods】 19 473 pregnant women were screened for irregular antibodies by microgel detection technology combined with anti-human globulin (IgG+ C3d), and the positive samples screened out were further confirmed to understand the types and titers of irregular antibodies. Irregular antibody type determination experiment: IgG type irregular antibody titer was determined after mercaptoethanol (2-Me) inactivated the serum of the irregular antibody positive specimen, and then IgG and IgM type were determined by comparing the titer levels of irregular antibody. Three hemolysis tests and total bilirubin tests were performed on umbilical cord blood during delivery to analyze the level of jaundice and the occurrence of HDN. 【Results】 53 cases of irregular antibodies other than the Rh blood group system were detected in 19 473 pregnant women, with a positive rate of 0.27%, mainly MNS and Lewis blood group system.The incidence of HDN was 39.6% (21/53). There were 27 cases of IgM, 7 IgG, and 19 IgM + IgG. Comparison of total bilirubin detection between the low titer group (≤8) and the high titer group (>8) : the latter was significantly higher than the former (P<0.05); IgG antibody subtypes: IgG1 of the latter significantly increased (P<0.05), and so was IgG3 in former (P<0.05). There was a significant positive correlation between IgG1, IgG3 and total bilirubin. The area under the curve of IgG1+ IgG3 for HDN diagnosis, the sensitivity and specificity were 0.953, 0.900, and 0.967, respectively. 【Conclusion】 Other than Rh blood group system, irregular antibodies are mainly distributed in MNS and Lewis blood group system. The incidence of HDN is higher in Kell, Duffy and Kidd blood group systems after producing irregular antibodies. Non-antibody types are mostly IgM type or IgM + IgG mixed, and the incidence of HDN is not high; Patients with poor maternal history, either high or low titer, can be classified into IgG1 and IgG3 in early stages, and those with Abnormal results should be included into the perinatal management of high-risk women with regular checking.
