AIM: To investigate the acute clinical manifestations of cosmetology-related ocular damage(COD).METHODS:Retrospective study. A total of 53 cases(89 eyes)with ocular damage caused by cosmetology from April 2016 to October 2021 were collected. The clinical features were analyzed, including age, gender, affected eye(s), clinical manifestations, injury cause, treatment procedures, and prognosis.RESULTS: All 53 patients were female, aged 22-45 years, with an average age of 28.4±6.7 years. Monocular injuries were observed in 17 patients, and binocular injuries in 36 patients. The same eye could exhibit two or more ocular damage simultaneously. The primary cosmetology procedures causing COD were eyeliner tattooing(38 eyes; 43%), eyelash extensions(18 eyes; 20%), removal of false eyelashes(11 eyes; 12%), mascara application(8 eyes; 9%), double eyelid surgery(6 eyes; 7%), and others(8 eyes; 9%). Major ocular damages included corneal damage(56 eyes; 63%), eyelid contact dermatitis(26 eyes; 29%), conjunctivitis(19 eyes; 21%), reactive eyelid edema(13 eyes; 15%), ocular surface foreign bodies(12 eyes; 14%), bacterial infection of the palpebral margin(10 eyes; 11%), and others(5 eyes; 6%). These 5 eyes included 1 eye(1%)with central retinal artery occlusion caused by periocular injection of hyaluronic acid. The majority of patients(74 eyes)recovered within 1-2 wk with appropriate treatment, while filamentosa keratitis appeared in 3 eyes and the eye with central retinal artery occlusion had poor prognosis.CONCLUSIONS: COD predominantly occurs in young and middle-aged females with cosmetology experience. The most common cosmetology procedure leading to COD is eyeliner tattooing, and corneal damage is the most significant type of COD. COD can be effectively prevented and treated, resulting in a generally favorable prognosis.

ObjectiveTo assess the quality of randomized controlled trials (RCTs) of compound traditional Chinese medicine (TCM) prescriptions in the treatment of nonalcoholic steatohepatitis (NASH), and to provide recommendations for standardizing the design and reporting of RCTs in this field. MethodsDatabases such as PubMed, Web of Science, Embase, the Cochrane Library, CNKI, VIP, and Wanfang Data were searched for RCTs of compound TCM prescriptions in the treatment of NASH published from January 1, 2018 to December 31, 2023, and the articles were screened and assessed based on the Cochrane risk-of-bias assessment tool (RoB 2), the unified standard for clinical trial reporting (CONSORT 2010), and CONSORT-CHM Formulas 2017 for compound TCM prescriptions. ResultsA total of 45 articles were finally included, and most of these studies were rated as high-risk bias by RoB 2.0. The analysis based on the CONSORT control checklist showed a relatively low reporting rate for most of the key items regarding the quality of RCT studies. ConclusionA relatively large risk of bias is observed in the clinical studies on compound TCM prescriptions in the treatment of NASH published in the past six years, which may lead to the poor quality of reporting and evidence. It is suggested that the top-level design of clinical studies should be taken seriously in addition to investigating the advantages of TCM, so as to improve the quality of clinical studies.

Objective To analyze the influence of shaping on the bending strength of bone plates and the influence of different locking nail distributions on plate force to provide biomechanical references for shaping plates and selecting different locking nail distributions.Methods Finite element simulation analysis of the four-point bending strength of a plate was performed according to the YY/T 0342-2020 standard.Theoretical analysis and finite element simulation method were used to analyze the force on prosthesis models with different lock-nail distributions.Results At 30° bending,the 3.7 mm-thick plate had 28%higher equivalent plastic strain than the 2.7 mm-thick plate.The 3.7 and 2.7 mm-thick plates had ultimate bending angles of 55° and 67°,respectively.The crease had little impact on the plate stress.The four-point bending strength and equivalent bending stiffness of the unshapeed structure were 2.64 N·m and 1.12 N·m2,respectively.The four-point bending strength and equivalent bending stiffness with the crease were 2.63 N·m and 1.10 N·m2,respectively.After forward and backward bending,the four-point bending strength of the plate decreased from 2.64 to 2.45 N·m by approximately 7.72%,and the equivalent bending stiffness decreased from 1.12 to 0.98 N·m2 by approximately 12%.The impact was obvious.After implantation of tamponade screws,the four-point bending strength of the single-hole plate improved significantly from 2.64 to 3.15 N·m,by approximately 19.32%and the equivalent bending stiffness increased from 1.12 to 1.14 N·m2,by approximately 2.1%.At least two locking holes were reserved on both sides of the fracture line.Not inserting the locking screw reduced the stress by approximately 50%compared with the full insertion of the locking screw.During 15-week postoperative walking without bone callus formation,the material stress of TC4 reached 852.7 MPa and yielding occurred.Conclusions In a clinical scenario where larger shaping is required,it is not suitable for plates with larger thicknesses and plate fractures are more likely to occur after large-thickness shaping.This can guide the clinical selection of plates with appropriate thickness based on the shaping angle,and tamponade screws can be implanted in extreme cases.Fixing locking screws clinically is recommended;however,a method of fixing the locking screws with full screws is not recommended.The biomechanical effect is best when two locking holes at both ends of the fracture line are maintained without fixing the locking screws.

Objective:To investigate the role and underlying mechanisms of methyltransferase (Mettl) 3 in the process of angiotensin Ⅱ (Ang Ⅱ)-induced pericyte-to-myofibroblast transdifferentiation and renal fibrosis.Methods:C57BL/6J mice were used, in cell experiments, mouse renal pericytes were isolated and cultured using magnetic bead sorting. These pericytes were then induced to transdifferentiate into myofibroblasts with 1×10 6 mmol/L Ang Ⅱ, which was the Ang Ⅱ group, while pericytes cultured in normal conditions served as the control group. Successful transdifferentiation was verified by immunofluorescence staining, Western blotting, and real-time reverse transcription PCR (RT-qPCR) for α-smooth muscle actin (α-SMA). The levels of m6A modifications and related enzymes (Mettl3, Mettl14), Wilms tumor 1-associated protein (WTAP), fat mass and obesity protein (FTO), ALKBH5, YTHDF1, YTHDF2, YTHDC1, YTHDC2, YTHDC3 were assessed by Dot blot, RT-qPCR and Western blot. Mettl3 expression was inhibited in cells using lentivirus-mediated Mettl3-shRNA transfection, creating sh-Mettl3 and Ang Ⅱ+sh-Mettl3 groups, while lentivirus empty vector transfection served as the negative control (Ang Ⅱ+sh-NC group). The impact of Ang Ⅱ on pericyte transdifferentiation was observed, and the expression of downstream phosphatidylinositol 3-kinase (PI3K)/AKT signaling pathway proteins, including PI3K, AKT, phosphorylated AKT at serine 473 (p-AKT (S473)), and phosphorylated AKT at threonine 308 (p-AKT (T308)), were examined. PI3K gene transcription was inhibited by co-culturing cells with actinomycin D, and the half-life of PI3K mRNA was calculated by measuring residual PI3K mRNA expression over different co-culture time. The reversibility of Mettl3 inhibition on Ang Ⅱ-induced pericyte-to-myofibroblast transdifferentiation was assessed by adding the AKT activator SC79 to the Ang Ⅱ+sh-Mettl3 group. In animal experiments, mice were divided into these groups: sham group (administered 0.9% sterile saline), Ang Ⅱ group (infused with Ang Ⅱ solution), sh-Mettl3 group (injected with Mettl3 shRNA lentivirus solution), Ang Ⅱ+sh-Mettl3 group (infused with Ang Ⅱ solution and injected with Mettl3 shRNA lentivirus solution), and Ang Ⅱ+sh-Mettl3+SC79 group (administered Ang Ⅱ solution and Mettl3 shRNA lentivirus, with an additional injection of SC79). Each group consisted of six subject mice. Blood pressure was measured using the tail-cuff method before and after surgery, and serum creatinine, urea, and urinary albumin levels were determined 4 weeks post-surgery. Kidney tissues were collected at 28 days and stained using hematoxylin-eosin (HE) and Masson′s trichrome to assess the extent of renal fibrosis. Results:Primary renal pericytes were successfully obtained by magnetic bead sorting, and intervened with 1×10 6 mmol/L Ang Ⅱ for 48 hours to induce pericyte-to-myofibroblast transdifferentiation. Dot blot results indicated higher m6A modification levels in the Ang Ⅱ group compared to the control group ( P<0.05). RT-qPCR and Western blot results showed upregulation of Mettl3 mRNA and protein levels in the Ang Ⅱ group compared to the control group (both P<0.05). In the Ang Ⅱ+sh-Mettl3 group, Mettl3 protein expression was lower than that in the Ang Ⅱ group, with reduced expression levels of α-SMA, vimentin, desmin, fibroblast agonist protein (FAPa) and type Ⅰ collagen (all P<0.05). Compared to the control group, PI3K mRNA expression level was elevated in the Ang Ⅱ group, along with increased p-AKT (S473) and p-AKT (T308) expressions. In the Ang Ⅱ+sh-Mettl3 group, PI3K mRNA expression and p-AKT (S473) and p-AKT (T308) levels were decreased (all P<0.05). The half-life of PI3K mRNA was shorter in the Ang Ⅱ+sh-Mettl3 group than that in the Ang Ⅱ+sh-NC group (2.34 h vs. 3.42 h). The ameliorative effect of Mettl3 inhibition on Ang Ⅱ-induced pericyte-to-myofibroblast transdifferentiation was reversible by SC79. Animal experiments showed higher blood pressure, serum creatinine, urea, and 24-hour urinary protein levels, and a larger fibrosis area in the Ang Ⅱ group compared to the sham group (all P<0.05). The fibrosis area was smaller in the Ang Ⅱ+sh-Mettl3 group than that in the Ang Ⅱ group ( P<0.05), but increased again upon addition of SC79. Conclusion:Mettl3-mediated RNA m6A epigenetic regulation is involved in Ang Ⅱ-induced pericyte-to-myofibroblast transdifferentiation and renal fibrosis, potentially by affecting PI3K stability and regulating the PI3K/AKT signaling pathway.

Objective To explore the effect of urine mixing degree on 24-hour urinary total protein(24 h UTP)in patients with chronic kidney disease(CKD).Methods From October 1,2023 to December 31,2023,30 hospitalized patients who needed to complete 24 h UTP testing in Zhongshan Hospital,Fudan University were selected.A 5 L unified container was used to collect urine for 24 hours.After collection and one hour's standing,the urine sample was divided into upper,middle,and lower equal parts according to volume,which was defined as direct-sampling group.Then,the urine samples were fully mixed with a magnetic stirrer and sampled again according to the above-mentioned three-equal sampling method,which was defined as mixed-sampling group.The generalized estimating equation was used to compare the urinary protein concentration before and after mixing and at different sampling location.Results The results of generalized estimating equation showed that after controlling the variable"sampling position",there was no significant difference in urinary protein concentration between the direct-sampling group and the mixed-sampling group.After controlling the variable"mixing method",there was still no significant difference in urinary protein concentration at different sampling positions.After adjusting the covariates such as age,gender,and estimated glomerular filtration rate(eGFR),the results were consistent.Conclusions With standard protocol,the entire 24-hour urine sample is a relatively even-distributed solution.After the total urine collection is completed,the temporary sample can be directly extracted from any level of the original urine within 1 hour,and the urine protein concentration of the sample multiplied by the urine volume can reflect the 24 h UTR.

Objective:To explore the prescription and medication law of Traditional Chinese Medicine (TCM) compounds in the treatment of vascular dementia (VD) based on patent database.Methods:TCM compounds with patents about VD were retrieved from Chinese patent announcement website of the State Intellectual Property Office and CNKI. The retrieval time was from the establishment to the databases to 31 st, March 2022. The frequency, clusteringand association analysis were carried out with the help of TCM inheritance auxiliary platform (V2.5). The medication law was analyzed. Results:154 TCM compound patents for the treatment of vascular dementia were screened, involving 227 kinds of Chinese materia medica. Among them, Acori Tatarinowii Rhizoma (44 times, 28.57%) was used more frequently, and the common medicinal pair was Salviea Miltiorrhizae Radix et Rhizoma- Acori Tatarinowii Rhizoma (17 times, 11.03%). The medicinal property was mainly warm, the taste was mainly sweet, and the meridian was mainly liver meridian. Those with high confidence based on association rules were " Corni Fructus -Acori Tatarinowii Rhizoma" (0.90), " Corni Fructus -Rehmannize Radix et Praeparata" (0.90). Based on the complex network, it was concluded that the core drugs were 14 groups such as " Rehmannize Radix et Praeparata- Cistanches Herba- Corni Fructus". The new prescriptions extracted by entropy cluster analysis included 7 groups such as " Rehmannize Radix et Praeparata, Cistanches Herba, Corni Fructus and Asparagi Radix". Conclusion:The treatment of VD by TCM compounds with national patents is mainly based on tonifying deficiency, promoting blood circulation and removing blood stasis, eliminating phlegm and dampness, expelling wind and dredging collaterals, opening orifices and resuscitation, which can provide reference for clinical practice and new drug research and development.

ObjectiveTo explore effect of modified Wuhutang on airway inflammation and expression of mucin (Muc) 5AC, signal transducer and activator of transcription 3 (STAT3), nuclear factor kappa B (NF-κB), and NOD-like receptor thermal protein domain associated protein 3 (NLRP3) in respiratory syncytial virus (RSV)-infected asthmatic mice. MethodSeventy male BALB/c mice of 6-8 weeks old were randomized into normal control (CON), asthma (ovalbumin, OVA), RSV infection-induced asthma (OVA+RSV), high-, medium-, and low-dose (4.08, 2.04, 1.02 g·kg-1·d-1, respectively) modified Wuhutang, and dexamethasone (Dxms, 0.1 g·kg-1d-1) groups (n=10). The model of asthma was established by sensitization and atomization inhalation with OVA. The RSV infection-induced asthma model was established by three consecutive RSV nasal infusions (1.0 × 106 PFU·mL-1, 50 μL). Wuhutang was administrated by gavage, and Dxms by intraperitoneal injection. The CON group was given the same amount of normal saline by gavage. The mice were anesthetized with 2.5% pentobarbital sodium 24 h after the last administration, and then the lung tissue was stained by hematoxylin-eosin (HE) and Van Gieson (VG) for observation of airway inflammation. The immunohistochemical assay was employed to detect the expression of Muc5AC. Western blot was employed to determine the protein levels of phosphorylated (p)-STAT3, STAT3, p-NF-κB, NF-κB, and NLRP3. ResultCompared with the CON group, the OVA group presented airway inflammatory cell infiltration, tissue hyperemia and edema, and collagen fiber deposition. The OVA+RSV group showed severer airway inflammatory cell infiltration and tissue hyperemia and edema than the OVA group. Compared with the OVA+RSV group, modified Wuhutang alleviated the airway inflammatory cell infiltration, tissue hyperemia and edema, and collagen fiber deposition, and the high-dose group had the best performance. Compared with the CON group, the OVA group and the OVA+RSV group showed increased expression level of Muc5AC (P<0.01). Compared with the OVA+RSV group, modified Wuhutang reduced the expression level of Muc5AC, and the reduction was significant in the high-dose group (P<0.05). Compared with the high-dose modified Wuhutang group, Dxms lowered the expression level of Muc5AC (P<0.05). Compared with the CON group, the OVA and OVA+RSV groups showed up-regulated protein levels of p-STAT3, p-NF-κB, and NLRP3 (P<0.05, P<0.01). Compared with the OVA+RSV group, modified Wuhutang down-regulated the protein levels of p-STAT3, p-NF-κB, and NLRP3 (P<0.01). Compared with the high-dose modified Wuhutang group, the Dxms group showed up-regulated levels of p-STAT3, p-NF-κB proteins (P<0.01). ConclusionModified Wuhutang can reduce airway inflammation and down-regulate the expression of Muc5AC, p-STAT3, p-NF-κB, and NLRP3 in RSV-infected asthmatic mice, which suggests that Wuhutang reduces airway inflammation in RSV-infected asthma by regulating the STAT3/NF-κB signaling pathway.
