OBJECTIVE:
To explore the mechanism of colon dialysis with Yishen Decoction (YS) in improving the autophagy disorder of intestinal epithelial cells in chronic renal failure (CRF) in vivo and in vitro.
METHODS:
Thirty male SD rats were randomly divided into normal, CRF, and colonic dialysis with YS groups by a random number table method (n=10). The CRF model was established by orally gavage of adenine 200 mg/(kg•d) for 4 weeks. CRF rats in the YS group were treated with colonic dialysis using YS 20 g/(kg•d) for 14 consecutive days. The serum creatinine (SCr) and urea nitrogen (BUN) levels were detected by enzyme-linked immunosorbent assay. Pathological changes of kidney and colon tissues were observed by hematoxylin and eosin staining. Autophagosome changes in colonic epithelial cells was observed with electron microscopy. In vitro experiments, human colon cancer epithelial cells (T84) were cultured and divided into normal, urea model (74U), YS colon dialysis, autophagy activator rapamycin (Ra), autophagy inhibitor 3-methyladenine (3-MA), and SIRT1 activator resveratrol (Re) groups. RT-PCR and Western blot were used to detect the mRNA and protein expressions of zonula occludens-1 (ZO-1), Claudin-1, silent information regulator sirtuin 1 (SIRT1), LC3, and Beclin-1 both in vitro and in vivo.
RESULTS:
Colonic dialysis with YS decreased SCr and BUN levels in CRF rats (P<0.05), and alleviated the pathological changes of renal and colon tissues. Expressions of SIRT1, ZO-1, Claudin-1, Beclin-1, and LC3II/I were increased in the YS group compared with the CRF group in vivo (P<0.05). In in vitro study, compared with normal group, the expressions of SIRT1, ZO-1, and Claudin-1 were decreased, and expressions of Beclin-1, and LC3II/I were increased in the 74U group (P<0.05). Compared with the 74U group, expressions of SIRT1, ZO-1, and Claudin-1 were increased, whereas Beclin-1, and LC3II/I were decreased in the YS group (P<0.05). The treatment of 3-MA and rapamycin regulated autophagy and the expression of SIRT1. SIRT1 activator intervention up-regulated autophagy as well as the expressions of ZO-1 and Claudin-1 compared with the 74U group (P<0.05).
CONCLUSION
Colonic dialysis with YS could improve autophagy disorder and repair CRF intestinal mucosal barrier injury by regulating SIRT1 expression in intestinal epithelial cells.

Objective:To explore the epidemiology and clinical characteristics of hospitalized patients with acute poisoning at the First Affiliated Hospital of Nanchang University in Jiangxi Province.Methods:Based on the electronic medical records management platform of the First Affiliated Hospital of Nanchang University, a retrospective analysis was conducted on hospitalized patients with acute poisoning based on ICD-10 disease codes from 2014 to 2021. The gender, age, residence, poison type, etiology, route of exposure, illness severity, diagnostic and therapeutic processes, hospital stay duration, and prognosis of patients were collected.Results:A total of 1 953 cases of acute poisoning were included, comprising 871 males (44.6%) and 1 082 females (55.4%). The age was (42.7±20.0) years, with 113 fatalities (5.8%). Urban residents accounted for 706 cases (36.1%) and rural residents for 1 247 cases (63.9%). The highest incidence occurred in the 41-60 age group. Suicide was the primary cause, constituting 1 318 cases (67.5%), followed by accidental ingestion or contact, with overdose being less frequent. Oral poison way was the predominant route (1 681 cases, 86.1%), followed by inhalation and contact. Pesticide poisoning was the predominant type of poisoning in this study, with 847 cases (43.4%), followed by drug poisoning and foodborne poisoning. Pesticide poisoning predominated among rural residents (79.2%), while drug poisoning was more prevalent among urban residents (53.5%).Conclusions:In this study, patients with acute poisoning exhibited predominantly female gender, hailed from rural areas, and primary etiology of poisoning was pesticide ingestion for suicidal intent. Targeted education and control measures should be carried out for the above high-risk areas, populations and poisons.

To explore the mechanism by which vinegar-processed Euphorbiae Pekinensis Radix regulates gut microbiota and reduces intestinal toxicity, this study aimed to identify key microbial communities related to vinegar-induced detoxification and verify their functions. Using a derivatization method, the study measured the content of short-chain fatty acids(SCFAs) in feces before and after vinegar-processing of Euphorbiae Pekinensis Radix. Combined with the results of previous gut microbiota sequencing, correlation analysis was used to identify key microbial communities related to SCFAs content. Through single-bacterium transplantation experiments, the role of key microbial communities in regulating SCFAs metabolism and alleviating the intestinal toxicity of Euphorbiae Pekinensis Radix was clarified. Fecal extracts were then added to a co-culture system of Caco-2 and RAW264.7 cells, and toxicity differences were evaluated using intestinal tight junction proteins and inflammatory factors as indicators. Additionally, the application of a SCFAs receptor blocker helped confirm the role of SCFAs in reducing intestinal toxicity during vinegar-processing of Euphorbiae Pekinensis Radix. The results of this study indicated that vinegar-processing of Euphorbiae Pekinensis Radix improved the decline in SCFAs content caused by the raw material. Correlation analysis revealed that Bifidobacterium was positively correlated with the levels of acetic acid, propionic acid, isobutyric acid, n-butyric acid, isovaleric acid, and n-valeric acid. RESULTS:: from single-bacterium transplantation experiments demonstrated that Bifidobacterium could mitigate the reduction in SCFAs content induced by raw Euphorbiae Pekinensis Radix, enhance the expression of tight junction proteins, and reduce intestinal inflammation. Similarly, cell experiment results confirmed that fecal extracts from Bifidobacterium-transplanted mice alleviated inflammation and increased the expression of tight junction proteins in intestinal epithelial cells. The use of the free fatty acid receptor-2 inhibitor GLPG0974 verified that this improvement effect was related to the SCFAs pathway. This study demonstrates that Bifidobacterium is the key microbial community responsible for reducing intestinal toxicity in vinegar-processed Euphorbiae Pekinensis Radix. Vinegar-processing increases the abundance of Bifidobacterium, elevates the intestinal SCFAs content, inhibits intestinal inflammation, and enhances the expression of tight junction proteins, thereby improving the intestinal toxicity of Euphorbiae Pekinensis Radix.

AIM: To analyze the screening status of neonatal fundus disease and the related influencing factors of common fundus retinal hemorrhage in Longhua District of Shenzhen, so as to provide references for the prevention, screening and intervention of neonatal fundus disease in clinical practice.METHODS: A total of 3 101 neonates who received fundus screening in the People's Hospital of Longhua, Shenzen from September 2019 to October 2022 were selected as research objects. The screening results were summarized, and the risk factors for neonatal retinal hemorrhage were analyzed by Logistic regression model.RESULTS: The detection rate of neonatal fundus abnormalities was 12.71%, and the detection rate of neonatal retinal hemorrhage was the highest(12.19%). The other types of fundus abnormalities included periretinal white focus, chromatosis, pigment shedding, choroid coloboma and nystagmus. Hemorrhage grade I accounted for the largest proportion of 378 neonates with retinal hemorrhage(75.66%). Follow-up found that different grades of retinal hemorrhage could be automatically absorbed over time without excessive intervention. Logistic analysis suggested that spontaneous delivery [OR=3.180, 95%CI(1.543~6.555)], twin pregnancy [OR=2.119, 95%CI(1.121~4.007)] and umbilical cord round the neck [OR=1.547, 95%CI(1.239~1.930)] were risk factors affecting neonatal retinal hemorrhage.CONCLUSION: Retinal hemorrhage is the most common type of fundus abnormalities in neonates. Spontaneous delivery, twin pregnancy and umbilical cord around the neck are risk factors of retinal hemorrhage. It is recommended that pay attention to the above factors and choose appropriate intervention means to avoid serious fundus complications.

PURPOSE:
Static progressive stretch (SPS) can be applied to treat chronic joint stiffness. However, the impacts of subacute application of SPS to the distal lower limbs, where deep vein thrombosis (DVT) is common, on venous thromboembolism remain unclear. This study aims to explore the risk of venous thromboembolism events following subacute application of SPS.
METHODS:
A retrospective cohort study was conducted on patients diagnosed with DVT following a lower extremity orthopedic surgery before being transferred to the rehabilitation ward from May 2017 to May 2022. Patients with unilateral lower limb comminuted para-articular fractures, transferred to rehabilitation ward for further treatment within 3 weeks after operation, followed up more than 12 weeks since initial manual physiotherapy, and diagnosed DVT by ultrasound before rehabilitation course were included in the study. Patients with polytrauma, without evidence of previous peripheral vascular disease or incompetence, had medication for thrombosis treatment or prophylaxis before the operation, detected with paralysis due to nervous system impairment, infected after operation during the regime, or with acute progression of DVT were excluded. The included patients were randomized to the standard physiotherapy and the SPS integrated groups for observation. Associated DVT and pulmonary embolism data were collected during the physiotherapy course to compare the groups. SSPS 28.0 and GraphPad Prism 9 were used for data processing. A p < 0.05 was set significant difference.
RESULTS:
In total of 154 patients with DVT participating in this study, 75 of them were treated with additional SPS for postoperative rehabilitation. The participants in the SPS group showed improved range of motion (12.3° ± 6.7°). However, in the SPS group, there was no difference in thrombosis volume between the start and termination (p = 0.106, p = 0.787, respectively), although difference was seen intra-therapy (p < 0.001). Contingency analysis revealed the pulmonary embolism incidence (OR = 0.703) in the SPS group compared to the mean physiotherapy.
CONCLUSION
The SPS technique is a safe and reliable option to prevent potential joint stiffness without aggravating the risk of distal DVT for postoperative patients suffering from relevant trauma.

OBJECTIVES:
To investigate the differences in non-suicidal self-injury (NSSI) behaviors between only-child and non-only-child adolescents with mood disorders.
METHODS:
A three-stage sampling method was used to perform a cross-sectional survey of 529 adolescents, aged 12-18 years, who had mood disorders and NSSI behaviors. These adolescents were sampled from the outpatient service of 20 mental hospitals in 9 provinces of China from August to November 2020. A self-made questionnaire was used to collect general demographic data. The Functional Assessment of Self-Mutilation, Beck Scale for Suicide Ideation, Kessler Psychological Distress Scale, Stress Mindset Measure-General, Multidimensional Scale of Perceived Social Support, Multidimensional Students' Life Satisfaction Scales, and Rosenberg Self-Esteem Scale were used to collect the information on self-injury behaviors and psychological factors in these adolescents.
RESULTS:
A total of 529 adolescents with mood disorders and NSSI behaviors were surveyed, among whom 375 were only-child adolescents and 154 were non-only-child adolescents. Compared with the non-only-child group, the only-child group had a significantly higher total score of Functional Assessment of Self-Mutilation (P<0.05) .The type and frequency of self-injury in the only-child group were significantly higher than those in the non-only-child group (P<0.05). Psychological analysis showed that compared with the non-only-child group, the only-child group had a significantly lower score of self-esteem (P<0.05) and significantly higher scores of psychological distress and depressive symptoms (P<0.05). The multiple linear regression analysis showed that the score of suicidal ideation was positively correlated with the frequency of NSSI behaviors in both only-child and non-only-child adolescents with mood disorders (P<0.05); in the only-child adolescents, the level of self-esteem was negatively correlated with the frequency of NSSI behaviors (P<0.05), and the score of stress perception was positively correlated with the frequency of NSSI behaviors (P<0.05); in the non-only-child adolescents, the score of anxious emotion was positively correlated with the frequency of NSSI behaviors (P<0.05).
CONCLUSIONS
Among the adolescents with mood disorders and NSSI behaviors, the only-child adolescents tend to have a higher frequency of self-injury and poorer mental health, and therefore, the only-child adolescents with mood disorders and NSSI behaviors need more attention.

ObjectiveTo observe the effect of classical prescription Gegen Qinliantang(GGQLT) on inflammatory factors and key targets in the inflammatory pathways mediated by lipopolysaccharide in KKAy mice and explore its mechanism in improving spontaneous type 2 diabetes mellitus (T2DM). MethodSixty-five SPF KKAy mice with spontaneous T2DM and 13 C57BL/6J mice (control) were selected in the barrier system and fed on a high-fat diet. The model was properly induced in 44 mice in the context of random blood glucose exceeding or equal to 13.9 mmol·L-1. Then the mice were assigned into a normal group (20 mL∙kg-1 normal saline), a model group (20 mL∙kg-1 normal saline), an acarbose group (3.9 mg∙kg-1), and high- and low-dose GGQLT groups (1.82 and 0.45 g∙kg-1), with 11 mice in each group. The mice in each group were treated correspondingly by gavage for eight weeks, once per day. Blood glucose and body weight were systematically evaluated. Twelve hours after the last administration, blood samples were collected from the eyes, and the serum and muscle and liver tissues were extracted. The levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and glucose transporter type 4 (GluT4) were detected by semi-quantitative enzyme-linked immunosorbent assay (ELISA). The protein expression of IκB kinase β (IKKβ) and nuclear factor-κB (NF-κB) in muscle tissues and Toll-like receptor 4 (TLR4) in liver tissues was detected by Western blot. ResultCompared with the normal group, the model group showed increased body weight and blood glucose (P<0.01). Compared with the model group, the acarbose group and the GGQLT groups showed reduced body weight and blood glucose (P<0.05, P<0.01). As revealed by ELISA results, compared with the normal group, the model group showed increased levels of TNF-α and IL-6 (P<0.01) and deceased GluT4 level (P<0.05). Compared with the model group, the groups with drug treatment showed reduced levels of TNF-α and IL-6 (P<0.05, P<0.01), and the acarbose group and the high-dose GGQLT group showed increased GluT4 level (P<0.05, P<0.01). As displayed by Western blot results, compared with the normal group, the model group showed increased protein expression of IKKβ, NF-κB, and TLR4 (P<0.01). Compared with the model group, the acarbose group and the GGQLT groups showed reduced protein expression of IKKβ, NF-κB, and TLR4 (P<0.05, P<0.01). ConclusionGGQLT can inhibit the inflammatory cascade effect and improve T2DM by down-regulating the levels of key inflammatory factors in the TLR4 pathway, inhibiting their activation, and increasing the translocation and activity of GluT4 on the basis of the regulation of intestinal flora.

Background Flurochloridone (FLC) can induce apoptosis in Sertoli cells, but the specific mechanism remains unknown. Objective To investigate the testicular cell apoptosis in mice as well as apoptosis and activation of endoplasmic reticulum stress in TM4 cell line induced by FLC through in vivo and in vitro study designs respectively, and study the role of inosital-requiring enzyme 1α (IRE1α)-c-Jun N-terminal kinase (JNK) signaling pathway in the process of FLC-induced apoptosis in TM4 cells through intervention study design. Methods Testicular tissues were collected from male C57BL/6 mice which were treated with 3, 15, 75, and 375 mg·(kg·d)−1 FLC by oral perfusion for 28 d. Apoptosis was observed by TUNEL staining, and the levels of apoptosis-related proteins were detected by Western blotting, including B-cell lymphoma-2 (Bcl-2), Bcl-2 interacting mediator of cell death (Bim), and Bcl-2 associated X protein (Bax). In the in vitro study, TM4 cells were treated with different concentrations of FLC (40, 80, and 160 μmol·L−1) for 6 h, then apoptosis rate was detected by flow cytometry, and the levels of apoptosis-related proteins (Bcl-2, Bim, and Bax) and endoplasmic reticulum stress-related proteins [glucose regulated protein 78 (GRP78), phosphorylated-protein kinase R like endoplasmic reticulum kinase (p-PERK), activating transcription factor 6 (ATF6), phosphorylated-inosital-requiring enzyme 1α (p-IRE1α), and phosphorylated-JNK (p-JNK)] were measured by Western blotting. In the intervention study, TM4 cells were pretreated with IRE1α phosphorylation inhibitor 4μ8C and JNK phosphorylation inhibitor SP600125 for 6 h, then treated with 160 μmol·L−1 FLC for 6 h. The levels of apoptosis-related proteins and endoplasmic reticulum stress-related proteins were measured by Western blotting, and cell viability was detected by cell counting kit-8. Results After the male C57BL/6 mice orally exposed to FLC for 28 d, apoptosis occurred in the seminiferous tubule. The protein expression level of Bcl-2, apoptosis inhibitor, was decreased in the 75 and 375 mg·(kg·d)−1 groups (P<0.05), and the protein expression levels of Bim and Bax, apoptosis promoters, were increased in the 75 and 375 mg·(kg·d)−1 groups respectively (P<0.05). The percentages of apoptotic cells in the 0, 40, 80, and 160 μmol·L−1 FLC groups were 2.7%±0.2%, 4.8%±1.3%, 9.4%±0.3%, and 13.2%±0.2%, respectively, increased significantly compared with the control group (P<0.05). The protein expression level of Bcl-2 also was decreased in the 160 μmol·L−1 FLC group (P<0.05), while the levels of Bim and Bax were increased in both of the 80 and 160 μmol·L−1 groups (P<0.05). The expression levels of endoplasmic reticulum stress-related proteins (GRP78, p-PERK, ATF6, p-IRE1α, and p-JNK) were increased (P<0.05) or showed a rising trend in TM4 cells. Pre-treatment with 4μ8C (25 and 50 μmol·L−1) and SP600125 (10 and 20 μmol·L−1) significantly down-regulated the protein expression levels of GRP78, p-IRE1α, p-JNK, and Bax induced by FLC (P<0.05) or in a downward trend. Both of the inhibitors alleviated the decreased cell viability induced by FLC (P<0.05) or in alleviating fashion. Conclusion FLC could induce apoptosis in mice testis and TM4 cell apoptosis through activating endoplasmic reticulum stress and IRE1α-JNK signaling pathway.
