Background: Numerous studies have shown that with the advancement of technology such as computers and cell phones, neck and back pain, and carpal tunnel syndrome have become common in daily life. Aim: Estimating the effectiveness of acupoint catgut embedding treatment for chronic neck pain. Materials and Methods: The study used a randomized clinical trial, double-blind, placebo-controlled design with treatment (n=40) and control (n=40) groups. The study included 80 patients with chronic neck pain, and the results were evaluated in the two groups before and after treatment using the “Visual Analogue Scale (VAS), “Neck Disability Index”, and “Quality of Life Questionnaire” (EQ-5D). Results: Acupoint catgut embedding and acupuncture treatment for chronic neck pain increased the neck’s range of motion by 2-5 degrees. Standard acupuncture treatment and acupoint catgut embedding treatment reduce neck pain and improve the neck disability index. Acupoint catgut embedding treatment improves the quality of life of patients with chronic neck pain, especially reducing anxiety and fear scores with statistical significance. Conclusion 1. Standard acupuncture and acupoint catgut embedding treatment are equally effective in relieving chronic neck pain. 2. Acupoint catgut embedding treatment increased the range of motion in the same way as standard acupuncture. 3. Acupoint catgut embedding treatment also reduced the patient’s Neck Disability Index and improved Quality of life.

ObjectiveThis study aims to investigate the effect of Dictamni Cortex on intestinal barrier damage in rats and its mechanism by untargeted metabolomics and targeted metabolomics for short-chain fatty acids （SCFAs）. MethodsRats were randomly divided into a control group， a high-dose group of Dictamni Cortex （8.1 g·kg^-1）， a medium-dose group （2.7 g·kg^-1）， and a low-dose group （0.9 g·kg^-1）. Except for the control group， the other groups were administered different doses of Dictamni Cortex by gavage for eight consecutive weeks. Hematoxylin-eosin （HE） staining was used to observe the pathological changes in the ileal tissue. Enzyme-linked immunosorbent assay （ELISA） was employed to detect the level of cytokines， including tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， and interleukin-1β （IL-1β）， in the ileal tissue of rats. Quantitative real-time fluorescence polymerase chain reaction （Real-time PCR） technology was used to detect the expression level of tight junction proteins， including zonula occludens-1 （ZO-1）， Occludin， and Claudin-1 mRNAs， in the ileal tissue of rats to preliminarily explore the effects of Dictamni Cortex on intestinal damage. The dose with the most significant toxic phenotype was selected to further reveal the effects of Dictamni Cortex on the metabolic profile of ileal tissue in rats by non-targeted metabolomics combined with targeted metabolomics for SCFAs. ResultsCompared with the control group， all doses of Dictamni Cortex induced varying degrees of pathological damage in the ileum， increased TNF-α （P<0.01）， IL-6 （P<0.01）， and IL-1β （P<0.01） levels in the ileal tissue， and decreased the expression level of ZO-1 （P<0.05， P<0.01）， Occludin （P<0.01）， and Claudin-1 （P<0.05） in the ileal tissue， with the high-dose group showing the most significant toxic phenotypes. The damage mechanisms of the high-dose group of Dictamni Cortex on the ileal tissue were further explored by integrating non-targeted metabolomics and targeted metabolomics for SCFAs. The non-targeted metabolomics results showed that 21 differential metabolites were identified in the control group and the high-dose group. Compared with that in the control group， after Dictamni Cortex intervention， the level of 14 metabolites was significantly increased （P<0.05， P<0.01）， and the level of seven metabolites was significantly decreased （P<0.05， P<0.01） in the ileal contents. These metabolites collectively acted on 10 related metabolic pathways， including glycerophospholipids and primary bile acid biosynthesis. The quantitative data of targeted metabolomics for SCFAs showed that Dictamni Cortex intervention disrupted the level of propionic acid， butyric acid， acetic acid， caproic acid， isobutyric acid， isovaleric acid， valeric acid， and isocaproic acid in the ileal contents of rats. Compared with those in the control group， the level of isobutyric acid， isovaleric acid， and valeric acid were significantly increased， while the level of propionic acid， butyric acid， and acetic acid were significantly decreased in the ileal contents of rats after Dictamni Cortex intervention （P<0.05， P<0.01）. ConclusionDictamni Cortex can induce intestinal damage by regulating glycerophospholipid metabolism， primary bile acid biosynthesis， and metabolic pathways for SCFAs.

ObjectiveTo explore the mechanism of action of Wuwei Shenqintang in improving pulmonary fibrosis by using ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry （UPLC-Q-TOF-MS） for metabolomic analysis of lung tissue and feces. MethodsA rat model with pulmonary fibrosis was established by intratracheal injection of 5 mg·kg^-1 bleomycin. The successfully modeled rats were randomly divided into a blank group， a model group， a prednisone （3.15 mg·kg^-1） group， and low-dose， medium-dose， and high-dose groups of Wuwei Shenqintang （4.586， 9.172， 18.344 g·kg^-1）. The rats were given intragastric administration once a day for 28 consecutive days. Hematoxylin-eosin （HE） staining was used to measure the pathological changes in lung and colon tissue， and Masson staining was used to detect the degree of pulmonary fibrosis. Enzyme-linked immunosorbent assay （ELISA） was used to detect the expression of interleukin-1β （IL-1β）， IL-6， IL-8， tumor necrosis factor-α （TNF-α）， and secretory immunoglobulin A （SIgA） in bronchoalveolar lavage fluid and intestinal mucus. Immunohistochemistry and reverse transcription quantitative polymerase chain reaction （Real-time PCR） were used to detect the expression of type Ⅰ collagen （Col-Ⅰ）， fibronectin （FN）， and alpha smooth muscle actin （α-SMA） in lung tissue. UPLC-Q-TOF-MS was used to study the changes in the metabolic network of lung tissue and feces in rats with pulmonary fibrosis treated with Wuwei Shenqintang， screen potential biomarkers for the treatment of pulmonary fibrosis by Wuwei Shenqintang， and perform pathway enrichment analysis. ResultsCompared with the blank group， the model group showed extensive inflammatory cell infiltration and continuous fibrotic lesions in lung tissue， colonic mucosal damage， and connective tissue hyperplasia. The expression of IL-6， IL-8， IL-1β， TNF-α， and SIgA in bronchoalveolar lavage fluid and intestinal mucus was significantly increased （P<0.01）. The expression of Col-Ⅰ， FN， and α-SMA proteins and mRNAs in lung tissue was significantly upregulated （P<0.01）. Compared with the model group， the groups of Wuwei Shenqintang exhibited significantly reduced inflammatory infiltration and blue collagen deposition in lung tissue， alleviated colonic damage， decreased expression of IL-6， IL-8， IL-1β， TNF-α， and SIgA in bronchoalveolar lavage fluid and intestinal mucus （P<0.01）， and reduced average absorbance values and mRNA expression of Col-Ⅰ， FN， and α-SMA in lung tissue （P<0.05， P<0.01）， with the prednisone group and the medium-dose and high-dose groups of Wuwei Shenqintang showing the most significant effects. The metabolomics results for lung tissue showed that compared with the blank group， the model group had 19 significantly different compounds （P<0.05， P<0.01）. Wuwei Shenqintang could normalize 17 of these compounds compared with the model group （P<0.05， P<0.01）. Fecal metabolomics results showed that compared with those in the blank group， there were 42 compounds with significant differences in the model group （P<0.05， P<0.01）. Compared with the model control group， Wuwei Shenqintang could normalize 41 of these compounds （P<0.05， P<0.01）. The combined analysis results indicated that Wuwei Shenqintang might inhibit pulmonary fibrosis by regulating the biosynthesis of phenylalanine， tyrosine， and tryptophan as well as the retinol metabolism pathway. ConclusionWuwei Shenqintang can ameliorate pulmonary fibrosis， which may be related to the regulation of the "lung-intestine axis".

ObjectiveTo investigate the mechanism of anti-pulmonary fibrosis of cannabidiol by ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS）. MethodSD rats were randomly divided into blank group， model group， prednisone group（3.15 mg·kg^-1） and cannabidiol low， medium and high dose groups（12， 36， 108 mg·kg^-1）， with 8 rats in each group. The rat model of pulmonary fibrosis was established by intratracheal injection of bleomycin（5 mg·kg^-1）， which was administered continuously for 28 days after successful modeling. The pathological changes of rat lung tissue were observed， and enzyme-linked immunosorbent assay（ELISA） was used to detect the expression levels of matrix metalloproteinase-7（MMP-7）， type Ⅱ alveolar cell surface antigen（KL-6）， pulmonary surfactant-associated protein A（SP-A） and SP-D in serum. The expression levels of type Ⅰ collagen（Col-Ⅰ） and fibronectin（FN） in lung tissues were detected by immunohistochemistry， and the expression of mucin 5 subtype AC（MUC5AC） was detected by immunofluorescence. UPLC-Q-TOF-MS was used to search for potential biomarkers and related metabolic pathways of cannabidiol in treating pulmonary fibrosis. ResultCompared with the blank group， there were a large number of inflammatory cell infiltration and continuous fibrosis lesions in the lung tissue of rats in the model group. Compared with the model group， the inflammatory infiltration and blue collagen deposition in the lung tissue of rats in the prednisone and cannabidiol groups were reduced. Compared with the blank group， the expressions of MMP-7， KL-6， SP-A and SP-D in serum of the model group were significantly increased（P<0.01）， while the expressions of MMP-7， KL-6， SP-A and SP-D in the prednisone and cannabidiol high dose groups were significantly decreased by comparing with the model group（P<0.05， P<0.01）. Compared with the blank group， the expression levels of Col-Ⅰ and FN in the lung tissues of the model group were significantly increased， and the fluorescence intensity of MUC5AC was significantly increased（P<0.01）. Compared with the model group， the expression levels of Col-Ⅰ and FN in the lung tissues of the prednisone and cannabidiol high dose groups were significantly decreased（P<0.05， P<0.01）， and the expression of MUC5AC was significantly decreased（P<0.01）. Compared with the blank group， a total of 18 differential compounds were screened out in the model group， which could be used as potential biomarkers， and cannabidiol could call back 16 of them， mainly involving 4 metabolic pathways（linoleic acid metabolism， phenylalanine， tyrosine and tryptophan biosynthesis， arachidonic acid metabolism， and niacin and niacinamide metabolism）. Compared with the blank group， the relative contents of potential biomarkers arachidonic acid and linoleic acid were significantly increased in the model group（P<0.05， P<0.01）， while the relative contents of 5，6-EET， L-tyrosine and niacinamide were significantly decreased（P<0.01）. Compared with the model group， cannabidiol could significantly reduce the relative contents of arachidonic acid and linoleic acid， and significantly increase the relative contents of 5，6-EET， L-tyrosine and niacinamide（P<0.01）. ConclusionCannabidiol has an intervention and remission effect on pulmonary fibrosis， and its mechanism may be related to linoleic acid metabolism， phenylalanine， tyrosine and tryptophan biosynthesis， arachidonic acid metabolism， niacin and niacinamide metabolism.

Objective:To study the current status of longitudinal extrauterine growth restriction (EUGR) in extremely preterm infants (EPIs) and to develop a prediction model based on clinical data from multiple NICUs.Methods:From January 2017 to December 2018, EPIs admitted to 32 NICUs in North China were retrospectively studied. Their general conditions, nutritional support, complications during hospitalization and weight changes were reviewed. Weight loss between birth and discharge > 1SD was defined as longitudinal EUGR. The EPIs were assigned into longitudinal EUGR group and non-EUGR group and their nutritional support and weight changes were compared. The EPIs were randomly assigned into the training dataset and the validation dataset with a ratio of 7∶3. Univariate Cox regression analysis and multiple regression analysis were used in the training dataset to select the independent predictive factors. The best-fitting Nomogram model predicting longitudinal EUGR was established based on Akaike Information Criterion. The model was evaluated for discrimination efficacy, calibration and clinical decision curve analysis.Results:A total of 436 EPIs were included in this study, with a mean gestational age of (26.9±0.9) weeks and a birth weight of (989±171) g. The incidence of longitudinal EUGR was 82.3%(359/436). Seven variables (birth weight Z-score, weight loss, weight growth velocity, the proportion of breast milk ≥75% within 3 d before discharge, invasive mechanical ventilation ≥7 d, maternal antenatal corticosteroids use and bronchopulmonary dysplasia) were selected to establish the prediction model. The area under the receiver operating characteristic curve of the training dataset and the validation dataset were 0.870 (95% CI 0.820-0.920) and 0.879 (95% CI 0.815-0.942), suggesting good discrimination efficacy. The calibration curve indicated a good fit of the model ( P>0.05). The decision curve analysis showed positive net benefits at all thresholds. Conclusions:Currently, EPIs have a high incidence of longitudinal EUGR. The prediction model is helpful for early identification and intervention for EPIs with higher risks of longitudinal EUGR. It is necessary to expand the sample size and conduct prospective studies to optimize and validate the prediction model in the future.

Objective:The repair of small and medium-sized defects in the oral has always been a challenge,free skin flap and distal pedicled tissue flaps are difficult to meet clinical needs,and the traditional under-chin flap has the risk of donor-area injury.This study aims to investigate the efficacy of V-shaped folded submental flap in the repair of small-sized and medium-sized oral defects. Methods:The clinical data of 28 patients with oral defect lesions,who were hospitalized in the Department of Stomatology,Third Xiangya Hospital of Central South University from March 2019 to December 2022,were retrospectively analyzed.Patients were divided into a V-shaped folded group(17 cases)and a conventional group(11 cases)according to different surgical methods.The V-shaped folded group was treated with a V-shaped folded submental flap for postoperative soft tissue repair,while the conventional group was treated with a conventional submental flap for repair.The postoperative follow-up time was 6-48 months.The survival status,repair time,and repair effect of the 2 groups were compared. Results:There was no significant difference in flap survival rate,flap size,flap preparation time,repair surgery time,and postoperative hospital stay between the 2 groups(all P>0.05).At 6 months after the surgery,the V-shaped folded group had no difficulty in raising the head or everting the lower lip,no"cat ear"deformity in the submental skin.Scars in the V-shaped folding group were hidden at the lower edge of the mandible.The wound aesthetics and functional scores in the V-shaped folded group were significantly higher than those in the conventional group(both P<0.05). Conclusion:The V-shaped foldable submental flap has the advantages of flexible design,simple preparation,reliable blood supply,and protection of the donor area,which can effectively protect the appearance of the chin and avoid functional disorders.

Objective:To summarize the clinical features and genetic characteristics of Congenital bile acid synthetic disorder type 3 (BASD3) disorder caused by CYP7B1 gene variation.Methods:This was a case series study. Clinical data and genetic results of 2 cases of congenital bile acid synthetic disorder type 3 caused by CYP7B1 gene variations in the Department of Infectious Diseases, Children′s Hospital of Fudan University at Xiamen and Department of Pediatrics, Women and Children′s Hospital, School of Medicine, Xiamen University from January 2021 to December 2023 were retrospectively collected and analyzed. Literature up to December 2023 was searched from electronic databases of China National Knowledge Infrastructure (CNKI), Wanfang Data and PubMed with the combined keywords of " Congenital bile acid synthetic disorder type 3""Oxysterol 7-alpha-hydroxylase""Oxysterol 7α-Hydroxylase Deficiency""BASD3" and "CYP7B1 liver" both in Chinese and English. The main clinical features and genetic characteristics of BASD3 disorder caused by CYP7B1 gene variations were summarized.Results:Two BASD3 patients, 1 male and 1 female, were admitted at the ages of 3 months and 18 days, and 2 months and 7 days, respectively. Both patients presented with neonatal cholestasis and hepatomegaly. Biochemical evidence indicated direct hyper-bilirubinemia with elevated aminotransferase levels, while gamma-glutamyltransferase (GGT) and total bile acid levels were normal or nearly normal. Patient 1 was a compound heterozygotes of the CYP7B1 gene variants c.525-526insCAAGTTGG(p.Asp176GInfs*15) and c.334C>T(p.Arg112Ter). Patient 1 jaundice resolved and liver function tests normalized after oral administration of chenodeoxycholic acid (CDCA). Patient 2 was homozygous for variant c.334C>T(p.Arg112Ter) in CYP7B1 gene. Patient 2 was in liver failure status already and not reactive to oral CDCA administration. Patient 2 received living-related liver transplantation for enhanced abdominal CT revealed a liver tumor likely vascular origin. Literature review revealed no cases of BASD3 reported in Chinese literature, including 2 patients in this study, while 12 patients (9 males and 3 females) were reported in 9 English literatures. All of the 12 manifested jaundice and hepatosplenomegaly in infancy, with cirrhosis, liver failure, kidney enlargement, hypoglycemia, and spontaneous bleeding in some cases, polycystic kidney disease was demonstrated in 5 cases of them. The c.334C>T (p.Arg112Ter) of the CYP7B1 gene was homozygous in 4 cases and compound heterozygous in 2 cases. Among the 12 children, 6 cases received CDCA treatment, while 6 cases not. Four survived with their native liver in the 6 cases who received CDCA therapy, while none in the 6 cases not received CDCA therapy.Conclusions:BASD3 is a rare hereditary cholestatic disorder. Markedly elevated levels of conjugated bilirubin and aminotransferases, with normal or nearly normal GGT and total bile acid levels can serve as diagnostic clue. c.334C>T is the most common pathogenic variant of the CYP7B1 gene. Timely administration of CDCA may save the liver.
