Objective: To determine the clinical efficacy of platelet-rich plasma (PRP) injection combined with warm acupuncture and moxibustion for treating patients with knee osteoarthritis and cold dampness obstruction syndrome. Methods: One hundred and twenty-eight patients with knee osteoarthritis and cold dampness obstruction syndrome who visited the Rehabilitation Department and Orthopedics Department of the Second Affiliated Hospital of Anhui University of Chinese Medicine from January 2023 to March 2024 and who met the inclusion and exclusion criteria were randomly divided into an experimental (n=64) and control group (n=64) using the random number table method. The experimental group was treated with PRP injection combined with warm acupuncture and moxibustion, whereas the control group was treated with normal saline injection combined with warm acupuncture and moxibustion treatment. PRP and normal saline injections were administered once every two weeks, a total of four times. Patients were treated with warm acupuncture and moxibustion once a day, six times a week, for four consecutive weeks. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Traditional Chinese Medicine (TCM) syndrome, visual analog scale (VAS), and Lysholm scores were determined before treatment, at week 4 and week 8 of treatment, and week 16 of follow-up. Serum interleukin-6 (IL-6), matrix metalloproteinase-3 (MMP-3), tumor necrosis factor-α (TNF-α), osteoprotegerin (OPG), bone gla protein(BGP), and cartilage oligomeric matrix protein (COMP) levels were compared between the two groups before and after 8 weeks of treatment. The clinical efficacy and safety indicators between the two groups were also compared. Results: There was no statistical difference in baseline data such as gender, age, disease duration, and body mass index between the two groups of patients. Compared with before treatment, both groups showed decreased WOMAC total and subscale, TCM syndrome total score and symptom scores, and VAS scores, and an increase in Lysholm scores at 4, 8, and 16 weeks after treatment. After treatment, serum IL-6, MMP-3, TNF-α, and COMP levels decreased, whereas serum OPG and BGP levels increased (P<0.05). Compared with the control group, patients in the experimental group showed decreased WOMAC total and subscale, TCM syndrome total score and symptom scores, and VAS scores, and an increase in Lysholm score at 4, 8, and 16 weeks after treatment. Compared with the control group, patients in the experimental group showed decreased serum IL-6, MMP-3, TNF-α, and COMP levels and an increase in serum OPG and BPG levels after treatment (P<0.05). The total effective rate of the experimental group was 91.94%, higher than that of the control group (81.97%; P<0.05). Conclusion PRP injection combined with warm acupuncture and moxibustion can improve various TCM symptoms, improve knee joint function and bone metabolism, and reduce inflammation in patients with knee osteoarthritis and cold dampness obstruction syndrome.

Objective: The purpose of this study was to investigate the different categories of males within two groups, namely a community male sample who engaged in online sexual activities (OSAs) and a subclinical male sample who were out of control in viewing pornography and had sought help. Additionally, the study aimed to determine the threshold for excessive OSAs in both samples. Methods: A total of 568 community adult males who engaged in OSAs and 567 adult males seeking help for pornography use were recruited online. A latent profile analysis (LPA) was used to identify potential profiles within the samples. Cut-point analyses were conducted to determine optimal cutoff scores for OSAs in each sample. Results: The LPA revealed two categories with different cutoff scores for OSAs within each sample. Excessive OSA can be a screening tool for detecting out-of-control behavior. More stringent criteria for identifying excessive OSAs can aid in distinguishing problematic pornography use (PPU) from impaired control in viewing sexually-explicit materials (SEMs). Two subcategories of loss of control emerged: high OSAs frequency impaired control and high viewing SEMs impaired control. Conclusion The threholds of excessive OSAs varies among community and sub-clinical male samples; this knowledge can assist in screening out individuals with impaired control and selecting individuals with PPU from the subclinical sample.

Objective This study aimed to investigate the effects of sitagliptin on the proliferation,apoptosis,in-flammation,and osteogenic differentiation of human periodontal ligament stem cells(hPDLSCs)in lipopolysaccharide(LPS)-induced inflammatory microenvironment and its molecular mechanism.Methods hPDLSCs were cultured in vitro and treated with different concentrations of sitagliptin to detect cell viability and subsequently determine the exper-imental concentration of sitagliptin.An hPDLSCs inflammation model was established after 24 h of stimulation with 1 μg/mL LPS and divided into blank,control,low-concentration sitagliptin(0.5 μmol/L),medium-concentration sita-gliptin(1 μmol/L),and high-concentration sitagliptin(2 μmol/L),high-concentrationsitagliptin+stromal cell derived factor-1(SDF-1)/CXC chemokine receptor 4(CXCR4)pathway inhibitor(AMD3100)(2 μmol/L+10 μg/mL)groups.A cell-counting kit-8 was used to detect the proliferation activity of hPDLSCs after 24,48,and 72 h culture.The apoptosis of hPDLSCs cultured for 72 h was detected by flow cytometry.After inducing osteogenic differentiation for 21 days,alizarin red staining was used to detect the osteogenic differentiation ability of hPDLSCs.The alkaline phosphatase(ALP)activity in hPDLSCs was determined using a kit.The levels of inflammatory factors[tumor necrosis factor(TNF)-α,interleukin(IL)-1β,and IL-6]in the supernatant of hPDLSCs culture were detected by enzyme-linked immu-nosorbent assay.The mRNA expressions of osteogenic differentiation genes[Runt-associated transcription factor 2(RUNX2),osteocalcin(OCN),osteopontin(OPN)],SDF-1 and CXCR4 in hPDLSCs were detected by real-time fluores-cence quantitative polymerase chain reaction(RT-qPCR).Western blot analysis was used to determine SDF-1 and CX-CR4 protein expression in hPDLSCs.Results Compared with the blank group,the proliferative activity,number of mineralized nodules,staining intensity,ALP activity,and RUNX2,OCN,OPN mRNA,SDF-1,and CXCR4 mRNA and protein expression levels of hPDLSCs in the control group significantly decreased.The apoptosis rate and levels of TNF-α,IL-1β,and IL-6 significantly increased(P<0.05).Compared with the control group,the proliferative activity,number of mineralized nodule,staining intensity,ALP activity,and RUNX2,OCN,OPN mRNA,SDF-1,and CXCR4 mRNA and protein expression levels of hPDLSCs in low-,medium-,and high-concentration sitagliptin groups in-creased.The apoptosis rate and levels of TNF-α,IL-1β,and IL-6 decreased(P<0.05).AMD3100 partially reversed the effect of high-concentration sitagliptin on LPS-induced hPDLSCs(P<0.05).Conclusion Sitagliptin may promote the proliferation and osteogenic differentiation of hPDLSCs in LPS-induced inflammatory microenvironment by activating the SDF-1/CXCR4 signaling pathway.Furthermore,it inhibited the apoptosis and inflammatory response of hPDLSCs.

ObjectiveTo observe the clinical efficacy of Chinese medicine combined with indirect moxibustion plaster on corona virus disease 2019 （COVID-19） patients during recovery period. MethodNinety patients of COVID-19 during the recovery period were randomly divided into a Chinese medicine group， an indirect moxibustion plaster group， and a combination group，with 30 cases in each group. According to the 10th edition of COVID-19 Diagnosis and Treatment Protocol，patients in the Chinese medicine group received oral Chinese medicine based on syndrome differentiation，one dose per day， twice a day. Patients in the indirect moxibustion plaster group were treated with indirect moxibustion plaster at Zusanli （ST 36）， Pishu （BL 20）， Dazhui （GV 14）， Feishu （BL 13）， Kongzui （LU 6）， and Tiantu （CV 22），once a day，40 min each time. Patients in the combination group were treated with Chinese medicine combined with indirect moxibustion plaster. Treatment lasted two weeks. Before and after treatment，the traditional Chinese medicine （TCM） symptom score，pulmonary computed tomography （CT） score，St. George's Respiratory Questionnaire （SGRQ） score，blood routine indexes ［white blood cell count （WBC），neutrophil count （NEUT），and lymphocyte count （LYM）］， and inflammatory indexes ［C-reactive protein （CRP），serum ferritin， and interleukin-6 （IL-6）］ were observed in the three groups. The clinical efficacy was evaluated. ResultAfter treatment，the scores of TCM symptoms，pulmonary CT， and SGRQ，CRP，IL-6，and ferritin in the three groups decreased（P<0.05），while WBC and LYM increased（P<0.05）， but there was no significant difference in NEUT. The above indexes in the combination group were better than those in the other two groups（P<0.05）. After treatment， the cured and markedly effective rate was 76.7% （23/30） in the combination group， 50.0% （15/30） in the Chinese medicine group， and 46.7% （14/30） in the indirect moxibustion plaster group. The cured and markedly effective rate of the combination group was significantly higher than that of the Chinese medicine group （χ²=4.593， P<0.05） and the indirect moxibustion plaster group （χ²=5.711， P<0.05）. The total effective rate was 96.7 % （29/30） in the combination group， 93.3% （28/30） in the Chinese medicine group， and 86.7% （26/30） in the indirect moxibustion plaster group. The total effective rate of the combination group was higher than that of the Chinese medicine group and the indirect moxibustion plaster group， but the differences were not statistically significant. ConclusionChinese medicine combined with indirect moxibustion plaster can effectively improve the clinical symptoms，promote pulmonary inflammation，blood routine indexes， and inflammatory indexes， and improve the quality of life of COVID-19 patients during the recovery period，which is more advantageous than Chinese medicine alone or indirect moxibustion plaster.
