OBJECTIVE: To evaluate the analgesic efficacy of ultrasound-guided high fascia iliaca compartment block (HFICB) in managing tourniquet-related pain following total knee arthroplasty (TKA). METHODS: A prospective randomized controlled trial was conducted involving 84 patients with severe knee osteoarthritis or rheumatoid arthritis who underwent unilateral TKA between March 2024 and December 2024. Patients were randomly assigned to two groups ( n=42) using a random number table. In the trial group, ultrasound-guided HFICB was performed preoperatively, with 0.2% ropivacaine injected into the fascia iliaca compartment. No intervention was administered in the control group. Baseline characteristics, including gender, age, surgical side, body mass index, and preoperative visual analogue scale (VAS) scores at rest and during movement, showed no significant difference between the two groups ( P>0.05). In both groups, a tourniquet was applied after osteotomy and before pulsed lavage, and removed after the closure of the first layer of the joint capsule. Postoperative assessments were conducted at 6, 12, 24, and 48 hours, including VAS scores at the tourniquet site (at rest and during movement), Bromage motor block scores, Ramsay sedation scores, and Bruggrmann comfort scale (BCS) scores to evaluate patient comfort. Additionally, the average tramadol consumption and incidence of nausea and vomiting within 48 hours postoperatively were recorded and compared. RESULTS: In the trial group and control group, VAS scores during movement at the tourniquet site significantly improved at all postoperative time points compared to preoperative levels ( P<0.05). VAS scores at rest increased transiently at 6 hours after operation in both groups, and then gradually decreased to the preoperative level. Except that there was no significant difference at 48 hours after operation in the trial group ( P>0.05), there were significant differences at other time points of two groups compared to preoperative score ( P<0.05). Except for VAS score at rest at 6 hours, VAS score during movement at 48 hours, and BCS comfort score at 48 hours ( P>0.05), the trial group showed significantly better outcomes than the control group in terms of VAS score at rest, VAS score during movement, Ramsay sedation scores, and BCS comfort scores at all other time points ( P<0.05). No significant difference was found in Bromage motor block scores between the groups ( P>0.05). Tramadol was used in 3 patients in the trial group and 7 patients in the control group within 48 hours after operation, the dosage was (133.30±14.19) mg and (172.40±22.29) mg, showing significant difference ( P<0.05). Nausea and vomiting occurred in 4 patients (9.5%) in the trial group and 3 patients (7.1%) in the control group, with no significant difference in incidence between groups ( P>0.05). CONCLUSION Ultrasound-guided HFICB provides effective analgesia for tourniquet-related pain following TKA, facilitates early postoperative functional recovery of the knee joint, and may serve as a valuable clinical option for postoperative pain management in TKA patients.

Objective: To evaluate the clinical effectiveness of combining electrical stimulation with manual massage in treating women′s myofascial pelvic pain (MPPS). Methods: A total of 93 MPPS patients were recruited and randomly divided into an infrared irradiation group (n=30), an electrical stimulation group (n=31) and a combination group (n=32). Those in the infrared group and the electrical stimulation group were given 30 minutes of infrared irradiation or electrical stimulation daily for 10 days, while the combined group was given a manual massage with electrical stimulation. The response to treatment was evaluated using a visual analogue scale (VAS) to rate discomfort, plus a physical examination, and surface electromyography results using Glazer′s protocol. The treatments′ efficacy and the recurrence of pain were evaluated 1 month after the treatment. Results: The average VAS ratings, resting potentials and their variability of the three groups all improved significantly after the treatment. The average VAS scores of the combined and electrical stimulation groups after the treatment were significantly lower than that of the infrared group. Moreover, the total effective rates of the combined group (96.87%) and the electrical stimulation group (80.65%) were significantly higher than that of the infrared group (56.67%), and the resting potential and variability of the former two groups were also significantly better. All of the above measurements among the combined group after the treatment were significantly better, on average, than in the electrical stimulation group. A month later the recurrence rate in the combined group (6.25%) was significantly lower than in the electrical stimulation group (25.81%) and the infrared group (56.67%). Conclusion Electrical stimulation combined with manual massage is effective in relieving myofascial pelvic pain.

Objective:To explore the reasons why patients with severe mental disorders and their family members refuse to participate in the community management and treatment service network.Methods:Totally 12 patients with severe mental disorders hospitalized and 7 family members in a ClassⅢ Grade A psychiatric hospital in Chengdu between January and May 2018 received semi-structural interviews using descriptive qualitative research methods. The content analysis and Nvivo 10.0 were used to organize and analyze the interview materials.Results:The five themes that affected refusal of patients with severe mental disorders and their family members to participate in the community management and treatment network were: poor perception of the patients, which covered the sub-themes of insufficient awareness of severe mental disorders and incorrect understanding of the community management and treatment service network; negative emotions of the patients and their family members, including the sub-themes of severe feelings of stigma and lack of trust; the patients and their family members actual needs were not met; the introverted personality traits of the patients; the decision-making game between the patients and the main caregiver of the family.Conclusions:Strengthening publicity, fully protecting the privacy of the patients, eliminating doubts, building a professional psychiatric prevention team, providing a diverse community management and treatment service network, and grasping the relevant drivers for the patient's refusal to participate in the community management and treatment service network can help enhance the enthusiasm of patients with severe mental disorders and their family members to participate in the community management and treatment service network.

BACKGROUND:Signal transducer and activator of transcription 3 (STAT3) is an important cytokine signaling pathway, which plays an important role in inflammatory diseases. However, it is unclear whether gene polymorphism of STAT3 is associated with rheumatoid arthritis in the Chinese Han population. OBJECTIVE: To explore the association of gene polymorphism of STAT3 with rheumatoid arthritis in the Chinese Han population. METHODS:Four tag-single-nucleotide polymorphisms (tag-SNPs) in STAT3 were selected from the Chinese Han population of HapMap database. The study was performed with 228 rheumatoid arthritis cases and 228 normal controls. Four tag-SNPs (rs12601982, rs2293152, rs8078731 and rs9912773) were examined by matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry. RESULTS AND CONCLUSION:The frequency of GG genotype at rs9912773 was 18.9% and 10.5% respectively in rheumatoid arthritis and control groups, and there was a significant difference between the two groups (P < 0.05). These results indicate the possible association between the STAT3 gene polymorphism at rs9912773 and the susceptibility of rheumatoid arthritis in the Chinese Han population.

BACKGROUND:Some overseas searchers have shown that,the midvastus approach in total knee arthroplasty(TKA)can reserve the complete medial structure of quadriceps femoris,improve the functional recovery of knee extension apparatus,but also preserve the blood supply of medial knee joint and maintain proprioceptive sense of knee joint.OBJECTIVE:To evaluate the early functional outcome of midvastus approach and standard medial parapatellar approach in TKA.DESIGN:A prospective,randomized,double-blind,comparative study.SETTING:Changzheng Hospital Affiliated to the Second Military Medical University of Chinese PLA.PARTICIPANTS:From March 2004 to March 2006,34 patients undergoing bilateral TKA simultaneOusly were admitted to the Changzheng Hospital Affiliated to the Second Military Medical University of Chinese PLA,including 7 males and 27 females.They aged 56-78 years with a mean of 70.5 years,and consisted of 24 cases with osteoarthritis,and 10 cases with rheumatoid arthritis;24 cases with bilateral genu varum,9 cases with bilateral enu valgum,and 1 case with lateral genu varum and contralateral genu valgum.Informed consents were obtained from all the included patients.Materials:Press Fit Condylar(PFC)Sigma knee prosthesis(DUPUY Company),the central tibial pad was added with a polyethylene prominence,while the corresponding femoral prosthesis was treated with anterioposterior steotomy,identical with the remained prosthesis.METHODS:The surgical approach of 34 patients was randomized into a midvastus approach in one knee and a standard medial parapatellar approach in the other knee.The comparison included the surgical parameters and clinical parameters.mevemnt,the time of performing an active straight leg raise,the time of reaching 90°knee flexion,range of motion and complications.RESULTS:All of 34 patients were involved in the result analysis.There was no significant difference in the surgical time botween the two roups.The assessment revealed significantly less blood loss[(286±29.8)Ml,(368±35.8)Ml,P＜0.05],fewer lateral release in valgus knee(20%,50%,P＜0.05),less pain in the first week(P＜0.05),earlier return of active straight-leg raise[(1.8±0.3)days,(4.5±0.8)days,P＜0.01],earlier reach of 90° knee flexion [(3.2±0.8)days.(7.1±1.2)days,P＜0.01]and greater range of motion at 45 day[(107±20)°,(98±12)°,P＜.05]in the midvastus approach group.CONCLUSION:The midvastus approach,which is based on diminished disruption of extensor mechanism and peripatellar pIexus of vessels,relieves pain and improves range of motion in the early rehabilitation period following TKA.
