OBJECTIVE: To observe the effect of moxibustion on small intestinal mucosal immune barrier in rats with diarrhea-predominant irritable bowel syndrome (IBS-D) and explore its underlying mechanisms. METHODS: Of 38 newborn rats from 4 healthy SPF pregnant rats, 12 neonatal rats were randomly selected in a normal group. IBS-D model was prepared by the combined measures for the rest rats, including neonatal maternal separation, acetic acid enema and chronic restraint stress. Twenty-four successfully-modeled rats were randomized into a model group and a moxibustion group, 12 rats in each one. In the moxibustion group, suspending moxibustion was delivered at bilateral "Tianshu" (ST25) and "Shangjuxu" (ST37), 20 min each time, once daily and for 7 consecutive days. Separately, before acetic acid enema (aged 35 days), after modeling (aged 45 days) and after intervention (aged 53 days), the body mass, loose stool rate (LSR) and and the minimum volume threshold when abdominal withdrawal reflex (AWR) scored 3 were observed in the rats of each group. After intervention (aged 53 days), using HE and PAS staining, the morphology of duodenum was observed, the length of villus and the depth of crypt were measured, the ratio of the length of villus to the depth of crypt was calculated; and the numbers of mucosal intraepithelial lymphocytes (IELs) and goblet cells were counted. With ELISA adopted, the contents of γ-interferon (IFN-γ), interleukin-4 (IL-4) and secretory immunoglobulin A (sIgA) in duodenal mucosa of rats were detected. The proportion of T cell subsets in duodenal mucosa was detected using flow cytometry. The microvilli and tight junctions of duodenal mucosal epithelial cells were observed by transmission electron microscopy, and the integrity of duodenal mucosa observed by scanning electron microscopy. RESULTS: Compared with the normal group, for the rats in the model group, the body mass, the minimum volume threshold when AWR scored 3, the length of duodenal villus and the the ratio of the length of villus to the depth of crypt, as well as the proportion of CD₈⁺ T subset were all reduced (P<0.01, P<0.05), the counts of goblet cells in duodenal mucosa decreased (P<0.01); LRS, the proportion of CD₄⁺ T subset and CD₄⁺/CD₈⁺, as well as the contents of IFN-γ, IL-4 and sIgA in duodenal mucosa and IFN-γ/IL-4 were all elevated (P<0.01); and the numbers of IELs rose (P<0.01). The morphology of duodenal mucosa was irregular, the villi got shorter, sparse and scattered, with uneven density. The morphology of epithelial cells was destroyed and the tight junctions damaged, with larger spaces. When compared with the model group, in the moxibustion group, the body mass, the minimum volume threshold when AWR scored 3, the length of duodenal villus and the ratio of the length of villus to the depth of crypt, as well as the counts of goblet cells in duodenal mucosa increased (P<0.01); LRS, the proportion of CD₄⁺ T subset, and CD₄⁺/CD₈⁺, as well as the contents of IFN-γ, IL-4 and sIgA in duodenal mucosa and IFN-γ/IL-4 were reduced (P<0.01); and the numbers of IELs was dropped (P<0.01). The morphology of duodenal mucosa was more regular, the villi were grew, got longer and arranged regularly, with even density. The morphology of epithelial cells was slightly destroyed, and the tight junctions partially damaged. CONCLUSION Moxibustion at "Tianshu" (ST25) and "Shangjuxu" (ST37) can reduce visceral hypersensitivity in IBS-D rats and relieve abdominal pain, diarrhea and other symptoms. Its effect mechanism may be related to the repair of small intestinal mucosal immune barrier and the improvement in the immune function in IBS-D.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a complex disease that is often accompanied by mental health disorders. However, the potential mechanisms underlying the heterogeneous clinical presentation of CP/CPPS remain uncertain. This study analyzed widely targeted metabolomic data of expressed prostatic secretions (EPS) and plasma to reveal the underlying pathological mechanisms of CP/CPPS. A total of 24 CP/CPPS patients from The Second Nanning People's Hospital (Nanning, China), and 35 asymptomatic control individuals from First Affiliated Hospital of Guangxi Medical University (Nanning, China) were enrolled. The indicators related to CP/CPPS and psychiatric symptoms were recorded. Differential analysis, coexpression network analysis, and correlation analysis were performed to identify metabolites that were specifically altered in patients and associated with various phenotypes of CP/CPPS. The crucial links between EPS and plasma were further investigated. The metabolomic data of EPS from CP/CPPS patients were significantly different from those from control individuals. Pathway analysis revealed dysregulation of amino acid metabolism, lipid metabolism, and the citrate cycle in EPS. The tryptophan metabolic pathway was found to be the most significantly altered pathway associated with distinct CP/CPPS phenotypes. Moreover, the dysregulation of tryptophan and tyrosine metabolism and elevation of oxidative stress-related metabolites in plasma were found to effectively elucidate the development of depression in CP/CPPS. Overall, metabolomic alterations in the EPS and plasma of patients were primarily associated with oxidative damage, energy metabolism abnormalities, neurological impairment, and immune dysregulation. These alterations may be associated with chronic pain, voiding symptoms, reduced fertility, and depression in CP/CPPS. This study provides a local-global perspective for understanding the pathological mechanisms of CP/CPPS and offers potential diagnostic and therapeutic targets.

Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Objective: To investigate the effects of glycogen synthase kinase-3β (GSK3β)/eukaryotic extension factor kinase 2 (eEF2K) signaling pathway on the process of pulmonary fibrosis through in vivo experiments, and find new ideas for clinical treatment of pulmonary fibrosis. Methods: The pulmonary fibrosis model of C57BL/6 male mice was induced by bleomycin with intratracheal injection at the dose of 2 mg/kg. After 14 days of modeling, animals were divided into model group, negative inhibition group and inhibition group (n=5 for each group), and control group was not processed. The inhibition group was treated with TDZD-8 (4 mg/kg) after modeling, the negative inhibition group was given DMSO solution after modeling, and the samples were collected after 28 days. Hematoxylin-eosin staining method was used to detect lung fibrosis in mice and scored according to Ashcroft scale. Expression levels of GSK3β, p-GSK3β, eEF2K, p-eEF2K (Ser70, Ser392, Ser470), precursor protein of matrix metalloproteinase-2 (pro-MMP-2), matrix metalloproteinase-2 (MMP-2), collagen I (Col I), collagen Ⅲ (Col Ⅲ) and α-smooth muscle actin (α-SMA) were detected by Western blot. Results: Compared with control group, the fibrosis score was up-regulated, the expression levels of GSK3β, p-GSK3β, p-eEF2K (Ser70, Ser392, Ser470), pro-MMP-2, MMP-2, Col I, Col Ⅲ and α-SMA were increased, while that of eEF2K was decreased in model group (P＜0.05). Compared with model group, the fibrosis score, expression levels of GSK3β, p-GSK3β, p-eEF2K (Ser70, Ser392, Ser470), pro-MMP-2, MMP-2, Col I, Col Ⅲ and α-SMA were decreased, but the expression level of eEF2K was increased in inhibition group (P＜0.05). Conclusion: GSK3β can activate eEF2K by phosphorylation at the sites of Ser70, Ser392 and Ser470, increase the contents of fibrosis indicators, promote the formation of pulmonary fibrosis, and aggravate lung tissue lesions.

OBJECTIVES: To study the clinical value of extracorporeal membrane oxygenation (ECMO) in the treatment of persistent pulmonary hypertension of the newborn (PPHN). METHODS: A retrospective analysis was performed on the medical data of 11 neonates with PPHN who were treated with ECMO in the Neonatal Intensive Care Unit of Zhongshan People's Hospital from January 2015 to December 2021, involving the neonates' general information, clinical diagnosis, laboratory results, duration of ECMO treatment, complications during ECMO treatment, length of hospital stay, and outcome. RESULTS: Of the 11 neonates, 10 (91%) had successful weaning from ECMO, and 8 (73%) survived. For the 11 neonates, the mean duration of ECMO treatment was (81±50) hours (range: 26 to 185 hours), the mean duration of ventilator use was (198±105) hours (range: 57 to 392 hours), and the mean length of hospital stay was (22±15) days (range: 2 to 49 days). The oxygenation index and blood lactate level were significantly improved after 24 hours of ECMO treatment among the 11 neonates (P<0.05). Ten neonates had significantly reduced pulmonary artery pressure after 24 hours of ECMO treatment (P<0.05). One neonate had a progressive increase in the pulmonary artery pressure during EMCO treatment, succumbing to death. This neonate was diagnosed with alveolar capillary dysplasia based on the histopathological findings of the lung tissue and whole-exome sequencing results. Among the 11 children, 5 had intracranial hemorrhage, 1 had disseminated intravascular coagulation, 1 had gastric hemorrhage, 2 had pulmonary hemorrhage, 1 had renal insufficiency, and 3 had bleeding at the puncture site during ECMO treatment. CONCLUSIONS ECMO is effective for the treatment of PPHN, however, the high incidence of complications of ECMO treatment suggests that it is important to carefully assess the indications and timing of ECMO treatment and improve the management of ECMO, which can improve the weaning rate and survival rate.

As an effective antipyretic medicine,Indigo Naturalis has a long history of application in the field of Chinese medicine.The content of organics,mainly indigo and indirubin,is about 10%. However,the active ingredients and mechanism of its antipyretic effect have not yet been fully elucidated. In view of this,they were investigated in this study with the rectal temperature change as an indicator and 2,4-dinitrophenol-induced fever rats as subjects. The content of PGE2 and c AMP in the hypothalamus and the serum levels of TNF-α,IL-1β and IL-6 were determined by ELISA. Moreover,the plasma samples of fever rats were analyzed by metabonomics in combination with UPLC-Q-TOF-MS for the exploration of potential biomarkers and the discussion on the antipyretic mechanism of Indigo Naturalis and its active ingredients. The results showed that the rising trend of rectal temperature in rats was suppressed 0. 5 h after the treatment with Indigo Naturalis,organic matter,indigo or indirubin as compared with the rats of model group( P < 0. 05),among which Indigo Naturalis and organic matter had better antipyretic effect. ELISA results showed that organic matter and indigo can inhibit the expression of PGE2 and c AMP( P<0. 01),while Indigo Naturalis and organic matter were effective in curbing the increase in TNF-α( P<0. 05). A total of 21 endogenous metabolites were identified from the plasma samples of the Indigo Naturalis,organic matter,indigo and indirubin groups,which were mainly involved in glycerophospholipid metabolism.

OBJECTIVE: To explore the clinical efficacy of silver needle lumbar and sacral spine approach in treating gluteal muscle syndrome. METHODS: Eighty-seven patients with gluteal muscle syndrome treated with silver needles in the Department of Rehabilitation Medicine of our hospital from September 2017 to September 2019 were selected. Except for symptoms of waist and hip pain and discomfort, all selected patients were examined by CT or MRI to confirm pathological imaging changes such as inflammatory exudation of the gluteal muscle. The 87 patients with gluteal muscle syndrome were divided into 2 groups according to the digital table method, and 42 patients in the lumbosacral approach group, including 19 males and 23 females, aged (50.70±12.45) years old, and disease duration of (1.63±1.27) years;45 cases in the buttock approach group, including 20 males and 25 females, aged (52.80±12.18) years old, with a course of disease of (1.78±1.22) years. The lumbosacral approach group was treated with spinal L to S bilateral articular process joints and L transverse process acupuncture needles, and the buttock approach group was treated with the gluteus medulla wing starting point and femoral trochanter stop. The VAS scores, soft tissue tenderness thresholds, and hip abductor muscle strength of the affected group were measured before and 4 weeks after treatment in the two groups. The clinical efficacy was also evaluated 4 weeks after treatment. RESULTS: After 4 weeks, the VAS score of the lumbosacral approach group was 1.26±0.70, and the buttock approach group was 1.18±0.74, which were significantly lower than those before treatment, but there was no statistical difference between the groups (>0.05). The soft tissue tenderness threshold and ipsilateral hip abductor muscle strength were (5.51±0.70) kg and (10.34±2.19) kg in the lumbosacral approach group, and (4.78±1.05) kg, (9.33±1.42) kg in the buttock approach group. The results in the lumbosacral approach group was better than those in the buttock approach group(<0.05). The clinical efficacy of the lumbosacral approach group:16 cases got an excellent result, 20 good, 5 fair and 1 poor;in the buttock approach group, 13 excellent, 17 good, 12 fair and 3 poor. The clinical efficacy between the two groups had statistical difference (<0.05). CONCLUSION In the treatment of gluteus medius syndrome with silver needle, lumbosacral approach and buttock approach can effectively relieve the pain. Compared with the improvement of soft tissue tenderness threshold and hip abductor muscle strength, the upper lumbosacral approach is more prominent, and the overall clinical effect is more significant.

Objective To investigate the prevalence and risk factors of Blastocystis infections among primary school students in Jiangjin District, Chongqing City. Methods A cross-sectional questionnaire survey was conducted among students sampled from a primary school in Jiangjin District, Chongqing City on April, 2018, and their stool samples were collected for microscopic examinations, in vitro culture and PCR assays to analyze the prevalence of Blastocystis infections and subtype of the parasite. In addition, the risk factors of Blastocystis infections among primary school students were identified using univariate analysis and multivariate logistic regression analysis. Results A total of 466 primary students were surveyed, and the subjects had a mean age of (9.81±1.66) years and included 236 males (50.64%) and 230 females (49.36%). The prevalence of Blastocystis infections was 15.24% (71/466) among the study students, and there was no significance difference in the prevalence between male and fe- male students (16.52% vs. 13.91%; χ2 = 0.616, P = 0.433). In addition, there was a significant difference in the prevalence of Blastocystis infections among grade 1 (6.35%, 4/63), grade 2 (5.17%, 3/58), grade 3 (21.74%, 15/69), grade 4 (25.30%, 21/83), grade 5 (10.19%, 11/108) and grade 6 students (20.00%, 17/85) (χ2 = 15.410, P = 0.009). There were four Blastocystis subtypes characterized (ST1, ST3, ST6 and ST7), in which ST6 was the most common subtype (45.07%, 32/71), followed by ST3 (25.35%, 18/71). Multivariate logistic regression analysis revealed that minority ethnicity [odds ratio (OR) = 4.259, 95% confidential inter- val (CI) : (1.161, 15.621)] and low maternal education level (primary school and below) [OR = 9.038, 95% CI: (1.125, 72.642)] were identified as risk factors of Blastocystis infection among primary school students in Jiangjin District, Chongqing City. Conclusions There is a high prevalence of Blastocystis infections detected among primary school students in Jiangjin District, Chongqing City, and ST6 and ST3 are predominant subtypes. Minority ethnicity and low maternal education level (primary school and below) are risk factors for Blastocystis infections in primary school students.

To systematically evaluate the adverse drug reaction(ADR) of Tripterygium Glycosides Tablets(TGT) in the treatment of rheumatoid arthritis(RA). Four Chinese databases(CNKI, VIP, WanFang, SinoMed) and three English databases(Cochrane Library, EMbase, PubMed), from the time of database establishing to August 2019, were systematically retrieved to collect literature on the treatment of all types of RA with TG. Screening literature and extracting data according to inclusion and exclusion criteria. All studies were assessed by using internationally recognized methodological quality assessment tools or reporting quality evaluation criteria, with data being extracted and Meta-analyzed. There were 79 studies included, randomized controlled trials(RCT) containing TGT in the treatment group, non-randomized controlled trials(non-RCT), case series, case reports, and RCT containing TGT only in the control group were covered. There were in the control group; 765 ADR of 2 214 patients in 30 RCT(treatment group given TGT), 11 non-RCT and 7 case reports. The results of Meta-analysis of these 48 literatures showed that the overall incidence of ADRs was 0.23(95%CI[0.22,0.24]); ADR mainly occured in the reproductive, gastrointestinal, skin and accessories, blood, hepatobiliary system damage and the incidence of ADR in systems mentioned about respectively were 0.14(95%CI[0.12,0.17]),0.07(95%CI[0.06,0.08]),0.06(95%CI[0.04,0.07]),0.04(95%CI[0.03,0.05]),0.04(95%CI[0.03,0.05]). Further subgroup analysis results showed that the incidence of total ADR, especially the gastrointestinal, reproductive and cutaneous ADR of patients with treatment alone was higher than that in those paients with MTX or MTX+LEF therapy; The incidence of ADR, especially the gastrointestinal ADR, was also positively correlated with daily dose and course of treatment, while the incidence of different systems ADR was also correlated with different drug manufacturers, for instance, damage on the female reproductive system occurs most frequently in Hunan manufacture TGT administration, same as the damage on skin and accessories induced by TGT from Jiangsu manufacture. Above all, The clinical treatment of TGT for RA will cause multi-system ADR, with the highest incidence in the reproductive system, followed by the gastrointestinal system, which is closely related to the way of medication(monotherapy), daily dose, course of medication and drug manufacturer. Therefore, it is recommended that, in the treatment of RA, using TGT in combination, low dose or short-course medication, take measures to protect the reproductive system, stomach and liver, and paying attention to the drug manufacturer as well response of patients during administration should be valued to avoid ADRs to the maximum possibility.
