OBJECTIVE To evaluate the efficacy and safety of total glucosides of paeonia （TGP） in the treatment of systemic lupus erythematosus （SLE）. METHODS Randomized controlled trial （RCT） about TGP combined with western medicine versus western medicine alone for SLE treatment were retrieved from PubMed， Embase， Cochrane Library， Web of Science， CNKI， VIP， Wanfang Data， and CBM. The search period spanned from the inception of each database to June 1， 2025. After literature screening， data extraction， and quality assessment of the included studies， Meta-analysis was performed using RevMan 5.4 software. RESULTS Fifteen RCTs， involving 1 318 patients， were included. Meta-analysis results showed that compared with western medicine alone， TGP combined with western medicine significantly improved clinical efficacy [OR＝4.96， 95%CI（3.41， 7.23）， P＜0.000 01]， complement 3 [MD＝0.18， 95%CI （0.13， 0.23）， P＜0.000 01] and complement 4[MD＝0.08， 般021） 95%CI （0.04， 0.11）， P＜0.000 01]， and reduced the levels of immunoglobulin G （IgG） [MD＝－3.10， 95%CI （－3.59，－2.62）， P＜0.000 01]， IgA [MD＝－0.68， 95%CI （－0.78， －0.58）， P＜0.000 01]， IgM [MD＝－0.43， 95%CI （－0.53，－0.34）， P＜0.000 01]， systemic lupus erythematosus disease activity index （SLEDAI） [MD＝－1.59， 95%CI （－2.20， －0.99）， P＜0.000 01]， recurrence rate [OR＝0.23， 95%CI （0.13， 0.42）， P＜0.000 01] and the incidence of adverse drug reactions [OR＝ 0.54， 95%CI （0.36， 0.82）， P＝0.004]. CONCLUSIONS TGP therapy can improve clinical efficacy of SLE patients， promote the restoration of immunoglobulins and complements， reduce SLEDAI and recurrence rate and has good safety.

OBJECTIVE: To observe the effects of Xingnao Kaiqiao acupuncture technique (for regaining consciousness and opening orifice) on methylation of N6-methyladenosine (m6A), and key methyltransferases and demethylases, so as to clarify the mechanism of acupuncture on cerebral ischemia-reperfusion injury (CIRI). METHODS: Of 68 male Sprague-Dawley rats of SPF grade, 15 rats were randomly selected as a sham-operation group, and the remaining rats were subjected to the model of middle cerebral artery occlusion using the suture ligation. CIRI was induced by ischemia for 2 h followed by reperfusion. Rats that failed to modeling or died were excluded. The rest 45 rats were randomly divided into three groups, i.e. model group, acupuncture group, and non-point acupuncture group, with 15 rats in each group. The rats in the acupuncture group were treated with acupuncture at bilateral "Neiguan" (PC6) and "Shuigou" (GV26). In the non-point acupuncture group, acupuncture was delivered at three non-points, located 3 mm below the bilateral midaxillary line and 3 mm lateral to the tip of the coccyx. One intervention was operated in these two acupuncture groups and the needles were retained for 30 min. Before modeling start and 2 h after ischemia, a laser speckle flowmeter was used to monitor the cerebral blood perfusion. In 2 h of ischemia and 24 h of reperfusion, the neurological behavioral score was evaluated. The volume of rat cerebral infarction was determined by triphenyltetrazolium chloride (TTC) staining, and the level of m6A methylation in ischemic cortical area was detected by Dot blot, and the protein and mRNA expression of the demethylase i.e. fat mass and obesity-associated protein (FTO), AlkB homolog 5 (ALKBH5) and key methyltransferases, i.e. methyltransferase-like 3 (METTL3), methyltransferase-like 14 (METTL14), and Wilms' tumor 1-associated protein (WTAP) in ischemic cortical area were detected by Western blot and real-time PCR. RESULTS: Cerebral blood perfusion decreased by>70% after 2 h ischemia. Compared with the sham-operation group, the neurobehavioral score and the percentage of cerebral infarction volume increased in the model group (P<0.01); the level of m6A methylation in the ischemic cortical area increased (P<0.01), the protein and mRNA expression of FTO decreased (P<0.01), and that of ALKBH5, METTL3, and METTL14 increased (P<0.01, P<0.05) in the model group. When compared with the model group and the non-point acupuncture group, the acupuncture group showed a decrease in the neurobehavioral score and the percentage of cerebral infarction volume (P<0.01), the level of m6A methylation in the ischemic cortical area was reduced (P<0.01, P<0.05), and the protein and mRNA expression of FTO was elevated (P<0.01). CONCLUSION Xingnao Kaiqiao acupuncture technique presents its protective effect on the brain in the rats with CIRI, which is related to up-regulating the expression of FTO and modulating m6A methylation.

Objective:To examine the therapeutic effects and molecular mechanisms of nuclear receptor NR4A1 in alleviating postoperative ileus (POI) in a rat model.Methods:Twenty-four Sprague-Dawley rats were randomly(random number) divided into four groups ( n=6/group): sham-operated control, POI model, POI model + NR4A1 stimultior (Cytosporone B, 13 mg/kg), and POI model + NR4A1 antagonist (DIM-C-pPhCO2Me, 2 mg/kg). After 24 hours, intestinal tissues and serum were collected for analysis. We assessed: (1) histopathological changes, (2) intestinal motility via propulsion rate, (3) NR4A1 expression by immunohistochemistry, (4) epithelial apoptosis via TUNEL assay, (5) inflammatory cytokines (IL-6, IL-4) by ELISA, (6) tight junction protein (occludin) by Western blot, and (7) p38MAPK/NF-κB pathway activation through combined western blot and immunofluorescence analyses. Results:Compared with sham controls, POI model rats showed (all P<0.05): significantly reduced NR4A1 expression, severe mucosal damage, increased inflammatory infiltration, elevated epithelial apoptosis, decreased occludin expression, impaired intestinal motility, upregulated pro-inflammatory cytokines (IL-6, IL-4), and activated p38MAPK/NF-κB signaling. NR4A1 activation with Cytosporone B significantly reversed these pathological changes (all P<0.05), while NR4A1 inhibition exacerbated them. Conclusions:NR4A1 activation attenuates POI by suppressing p38MAPK/NF-κB-mediated inflammation and preserving intestinal barrier function, suggesting its potential as a therapeutic target for postoperative ileus.

ObjectiveBased on the experience of traditional quality evaluation， the quality of Atractylodis Macrocephalae Rhizoma（AMR） with different production methods such as direct seeding， transplanting after seedling raising， topping and non-topping， and difference in growth years was compared. MethodVernier caliper was used to measure the trait data of AMR in different production methods. Paraffin sections of AMR with different production methods were made by saffron solid green staining， and the microstructure was observed. The contents of water-soluble and alcohol-soluble extracts in AMR with different production methods were determined according to the 2020 edition of Chinese Pharmacopoeia. The content of water-soluble total polysaccharides in AMR with different production methods was detected by sulfuric acid-anthrone method. Fiber analyzer was used to detect the content of fiber components in AMR with different production methods. The contents of monosaccharides， oligosaccharides and some secondary metabolites in AMR with different production methods were detected by ultra performance liquid chromatography（UPLC）， and the differences of chemical components were compared by multivariate statistical analysis methods such as principal component analysis（PCA） and partial least squares-discriminant analysis（PLS-DA）. ResultIn terms of traits， the 3-year-old AMR with direct seeding and without topping was close to the high-quality AMR with "phoenix-head and crane-neck， strong sweetness and clear aroma" recorded in ancient materia medica， followed by the 3-year-old AMR with topping after transplanting， while the 2-year-old AMR with topping after transplanting with high market circulation rate was generally fat and strong with mild odor. In the microscopic aspect， the arrangement of xylem vessels and fiber bundles in the 3-year-old samples formed two obvious rings. Compared with the 2-year-old samples cultivated in Bozhou and Zhejiang， the 3-year-old samples without topping after transplanting had more wood fibers. In terms of chemical composition， the contents of 70% ethanol extract， fructose， glucose， sucrose， 1-kestose， atractylenolide Ⅰ， chlorogenic acid， neochlorogenic acid， cryptochlorogenic acid and other components in 3-year-old AMR with direct seeding and without topping were significantly higher than those in the other three samples（P<0.05）. The contents of cellulose， 70% ethanol extract， sucrose， atractylenolide Ⅰ， atractylone and other components in 3-year-old AMR with topping after transplanting were significantly higher than those in the 2-year-old AMR with high market circulation rate（P<0.05）， while the contents of water-soluble extract and water-soluble total polysaccharides in 2-year-old samples with topping after transplanting were significantly higher than those in the 3-year-old AMR with topping after transplanting， direct seeding and without topping（P<0.05）. ConclusionUnder the current mainstream production mode， too much manual intervention makes AMR heavily enriched in polysaccharides and increased the yield， but the accumulation of sweet substances， fragrant substances and fiber substances is insufficient， which affects its quality. The current quality standard of AMR has some shortcomings in guiding the high quality production of it， it is suggested to revise the quality standard of AMR， supplement the quantitative analysis of secondary metabolites， and strengthen the production of imitation wild AMR.

It described the diagnosis and treatment of a kidney transplant recipient simultaneously infected with Mycobacterium tuberculosis and Talaromyces marniffei (TM). In early stage of treatment, this case was misdiagnosed as a single infection of Mycobacterium tuberculosis tuberculosis. However, anti-tuberculosis treatment was ineffective and general condition continued to deteriorate. Pathogenic examination yielded a definite diagnosis of skin and soft tissue infection caused by TM. The patient was cured with amphotericin B cholesterol sulfate complex, voriconazole and itraconazole successively while tapering the intensity of immunosuppressants. Transplanted kidney function normalized. There was no recurrence during a follow-up period of over 1 year.

Lipophagy, the selective engulfment of lipid droplets (LDs) by autophagosomes for lysosomal degradation, is critical to lipid and energy homeostasis. Here we show that the lipid transfer protein ORP8 is located on LDs and mediates the encapsulation of LDs by autophagosomal membranes. This function of ORP8 is independent of its lipid transporter activity and is achieved through direct interaction with phagophore-anchored LC3/GABARAPs. Upon lipophagy induction, ORP8 has increased localization on LDs and is phosphorylated by AMPK, thereby enhancing its affinity for LC3/GABARAPs. Deletion of ORP8 or interruption of ORP8-LC3/GABARAP interaction results in accumulation of LDs and increased intracellular triglyceride. Overexpression of ORP8 alleviates LD and triglyceride deposition in the liver of ob/ob mice, and Osbpl8-/- mice exhibit liver lipid clearance defects. Our results suggest that ORP8 is a lipophagy receptor that plays a key role in cellular lipid metabolism.

By summarizing and analyzing the research status of the influence of needling different acupoints on heart rate variability (HRV) and autonomic nervous function, it is found that Neiguan (PC 6), Zusanli (ST 36) and Shenmen (HT 7) are common acupoints for HRV analysis involving Tongli (HT 5), Hegu (LI 4), Taichong (LR 3), Zhongwan (RN 12), Danzhong (RN 17), Xinshu (BL 15), Shenshu (BL 23) and other acupoints. Different acupoints have different influences on HRV but followed by some rules, which are possibly related to the efficacy of acupoints, meridian tropism and acupoint distributions. Needling on the same acupoint also has different influences on HRV, which is possibly affected by sample size, intervention object, data processing method and other factors, so more standardized measurement process is required in further studies.

Postzygotic mutations are acquired in normal tissues throughout an individual's lifetime and hold clues for identifying mutagenic factors.Here,we investigated postzygotic mutation spectra of healthy individuals using optimized ultra-deep exome sequencing of the time-series samples from the same volunteer as well as the samples from different individuals.In blood,sperm,and muscle cells,we resolved three common types of mutational signatures.Signatures A and B represent clock-like mutational processes,and the polymorphisms of epigenetic regulation genes influence the pro-portion of signature B in mutation profiles.Notably,signature C,characterized by C＞T transitions at GpCpN sites,tends to be a feature of diverse normal tissues.Mutations of this type are likely to occur early during embryonic development,supported by their relatively high allelic frequencies,presence in multiple tissues,and decrease in occurrence with age.Almost none of the public datasets for tumors feature this signature,except for 19.6％of samples of clear cell renal cell carcinoma with increased activation of the hypoxia-inducible factor 1(HIF-1)signaling pathway.Moreover,the accumulation of signature C in the mutation profile was accelerated in a human embryonic stem cell line with drug-induced activation of HIF-1α.Thus,embryonic hypoxia may explain this novel signature across multiple normal tissues.Our study suggests that hypoxic condition in an early stage of embryonic development is a crucial factor inducing C＞T transitions at GpCpN sites;and indi-viduals'genetic background may also influence their postzygotic mutation profiles.

Objective:To explore the methods, complications and follow-up results of limb salvage for primary malignant tumors of the femoral shaft.Methods:From October 2006 to October 2019, 41 cases of primary malignant tumors of femoral shaft were analyzed retrospectively, 37 cases were followed up, including 22 males and 15 females, aged 8-46 years with an average age of 20.56±4.72 years old. All the lesions were located in the femoral shaft, and The Enneking stage was IIB. Tumor lesion ranged in the femur from 10 cm to 24 cm, and there was no pathological fracture. Pre-operative puncture biopsy was performed in all cases.22 cases were confirmed as osteosarcoma, 8 as chondrosarcoma, 5 as Ewing sarcoma, 2 as malignant fibrous histiocytoma. Neoadjuvant chemotherapy has been used to treat both osteosarcoma and Ewing sarcoma. Among the 37 patients, 8 cases of patients received total femoral prosthesis replacement, 14 cases of intramedullary nail fixation with allogenic bone graft, 8 cases of allograft-prosthetic composite (APC), and 7 cases of 3D printed prosthesis. The limb function was graded according to MSTS 93 system.Results:37 out of 41 patients were followed up, and the average follow-up time was 23.15±16.74 months (6-62 months). There were 9 patients with pulmonary metastases (26.47%), among which 6 patients passed away due to multiple metastases. 28 patients survived without tumor at last follow-up. The MSTS score was18-28 (average of 22.55±2.57). The average score of 3D printing prosthesis group was 27±1.74, allogeneic bone transplantation group was 22.85±2.59, total femoral prosthesis replacement group was 20.25±2.25, and the APC prosthesis group was 20.5±2.07. There was statistical difference between 3D printing group and other groups. The overall excellent and good rate of lower limb function was 79.41%, in which the 3D group was 100%, allogeneic bone group was 78.5%, APC prosthesis group was 87.5%, total femoral prosthesis replacement group was 62.5%. There was no statistical difference in the excellent and good rate of limb function among the groups. There weren't any cases of hip joint dislocation after total femoral prosthesis replacement. Delayed union of bone healing was seen in 3 cases of allogeneic bone transplantation and 2 cases APC patients. One patient suffered from the postoperative hemorrhage-related diseases-sciatic nerve compression, and the nerve recovered after emergency debridement. One patient suffered from poor wound healing. The overall complication rate was 24.32% (9/37).Conclusion:The patients with primary malignant tumors of the femoral shaft can effectively recover the lower extremity function by choosing the appropriate surgical scheme, in order to achieve the purpose of limb preservation and improve the quality of life of the patients. 3D printing prosthesis provides a new choice in the treatment of femoral shaft tumors.
