Objective To evaluate the clinical efficacy of tendon-regulating and bone-setting manipulation combined with subtalar joint arthroereisis in the treatment of adolescent flexible flatfoot.Methods A retrospective analysis was conducted on the clinical data of 86 children with flexible flatfoot treated at Dongguan Hospital of Guangzhou University of Chinese Medicine(Dongguan Traditional Chinese Medicine Hospital)between December 2022 and February 2024.Based on pre-treatment physician-patient communication,the children were divided into an trial group(44 cases)and a control group(42 cases).The control group received subtalar joint arthroereisis alone,while the trial group received additional tendon-regulating and bone-setting manipulation just once one day before surgery and once weekly postoperatively for one month,with a follow-up period of no less than 6 months.The Visual Analogue Scale(VAS)pain score,American Orthopaedic Foot & Ankle Society(AOFAS)ankle-hindfoot score,Tegner activity score,radiographic parameters,and static plantar pressure parameters of the two groups were observed before and after surgery.Results(1)Regarding clinical data,all surgeries were successfully completed in both groups.There were no statistically significant differences in perioperative general data,including operative time,hospital stays,and complication rates(P＞0.05).All children were followed up for no less than 6 months.The results showed that at the final follow-up,the VAS pain score,AOFAS ankle-hindfoot score,and Tegner activity score were significantly improved in both groups compared to preoperative values(P＜0.05),and the improvement in the trial group was significantly greater than that in the control group(P＜0.05 or P＜0.01).(2)Regarding radiographic parameters,at the final follow-up,the talonavicular coverage angle(TNCA),talus-first metatarsal angle(T1MT),talus-second metatarsal angle(T2MT)on weight-bearing anteroposterior radiographs,and the Meary angle between the talus and the first metatarsal as well as calcaneal Pitch angle(Pitch angle)on weight-bearing lateral radiographs were significantly improved in both groups compared to preoperative values(P＜0.05).The improvement in Meary angle,T1MT angle,and T2MT angle in the trial group was significantly greater than that in the control group(P＜0.01).However,there were no statistically significant differences in TNCA and Pitch angle between the two groups at the final follow-up(P＞0.05).(3)Regarding plantar pressure testing,at the 1-month postoperative follow-up,the forefoot load increased significantly in both groups compared to preoperative values(P＜0.05),while the midfoot load significantly decreased(P＜0.05).The increase in forefoot load and decrease in midfoot load in the trial group were significantly greater than those in the control group(P＜0.05 or P＜0.01).However,there were no statistically significant differences in hindfoot load between preoperative and postoperative values or between the two groups at the 1-month follow-up(P＞0.05).Conclusion For adolescent flexible flatfoot,tendon-regulating and bone-setting manipulation combined with subtalar joint arthroereisis can effectively restore the arch,improve foot mechanical imbalance,thereby correcting flatfoot deformity and enhancing joint motor function.

Objective:To observe any effect of combining visual deprivation training (VDT) with repeated low-frequency transcranial magnetic stimulation (rTMS) in the treatment of lower limb motor dysfunction among stroke survivors.Methods:Fifty stroke survivors were randomly assigned to either a control group or an experimental group ( n=25 each). In addition to routine rehabilitation treatment, the control group received rTMS targeting the primary motor cortex (M1, lower limb representation area) of the unaffected hemisphere, while the experimental group also received VDT. Before and after 4 weeks of the treatments, everyone′s lower limb motor function, balance, gait and ability in the activities of daily living were evaluated using the Fugl-Meyer lower extremity assessment (FMA-LE), the root mean square (RMS) values generated through surface electromyography of the affected tibialis anterior muscle, the Berg Balance Scale (BBS), the Timed Up and Go Test (TUGT), the Tinetti Gait Assessment (TGA), and the modified Barthel Index (MBI). Results:After the treatment, both groups showed significant improvements in their average FMA-LE, BBS, TUGT, TGA and MBI results, as well as in the RMS values of the affected tibialis anterior muscle. The experimental group showed significantly greater improvement compared to the control group.Conclusions:The combination of VDT and low-frequency rTMS can effectively improve the lower limb motor function, balance and gait of stroke survivors. It is more effective than rTMS alone. The combined therapy is worthy of clinical application and promotion.

OBJECTIVE: To explore the effectiveness of the flexor digitorum longus (FDL) transfer combined with single-bundle spring ligament reconstruction and medial displacement calcaneal osteotomy in the treatment of stage ⅠAB progressive collapsing foot deformity (PCFD). METHODS: Between January 2019 and September 2023, 19 patients (19 feet) with stage ⅠAB PCFD were treated with FDL transfer combined with single-bundle spring ligament reconstruction and medial displacement calcaneal osteotomy. There were 11 males and 8 females, aged 18 to 60 years, with an average age of 45.5 years. Nine cases were on the left foot and 10 cases on the right foot. The disease duration was 9-21 months, with an average of 12.3 months. Postoperatively, the effectiveness was evaluated by visual analogue scale (VAS) for pain, American Orthopaedic Foot and Ankle Society (AOFAS) score, and Tegner score. Based on X-ray films, the talonavicular coverage angle (TNCA), talus-first metatarsal angle (T1MT), Meary angle, and pitch angle were measured. The plantar pressure parameters of the foot were measured by the Footscan plantar pressure measurement system, including peak pressure and load of the forefoot, midfoot, and hind foot. The patients' satisfaction with the surgical outcome was evaluated. RESULTS: All 19 surgeries were successfully completed. One patient had poor incision healing after operation, while the incisions of the remaining patients healed by first intention. All patients were followed up 12-28 months (mean, 16.8 months). At last follow-up, the VAS score significantly decreased compared with that before operation, and the AOFAS score and Tegner score significantly increased ( P<0.05). Radiological measurements showed that the TNCA, T1MT, Meary angle, and Pitch angle all significantly improved compared with those before operation ( P<0.05). Plantar pressure tests indicated that the peak pressures of the forefoot and midfoot significantly reduced compared with those before operation ( P<0.05), while the peak pressure of the hind foot showed no significant change ( P>0.05). The forefoot load significantly increased and the midfoot load decreased compared with those before operation ( P<0.05), while the hind foot load showed no significant change ( P>0.05). The total satisfaction rate of patients with the surgical outcome (very satisfied+satisfied) reached 84.2% (16/19). CONCLUSION The FDL transfer combined with single-bundle spring ligament reconstruction and medial displacement calcaneal osteotomy can effectively correct the stage ⅠAB PCFD, improve the abnormal distribution of plantar pressure and load, alleviate foot pain symptoms, and improve foot movement function. The patient's satisfaction is high. However, the long-term effectiveness still needs to be further observed and clarified.

OBJECTIVE To study the antibiotic resistance gene of qacE△1-sul1 in Acinetobacter baumannii isolated from inpatients in Urumqi and the distribution and difference of qacE△1-sul1 genotype in Xinjiang. METHODS Bacterial strains were identified by system of API and antibiotic susceptibility test was detected by K-B and microdilution methods according CLSI.PCR was used to determine the gene of qacE△1-sul1 and compared with the sequences in GenBank. RESULTS Antibiotic resistance phenotypes showed the resistance rate to cefataxime and tetracycline was the highest(100.0%),but that to cefoperazone/sulbactam was the lowest.The positive rate of qacE△1-sul1 gene in A.baumannii was 52.2%. CONCLUSIONS High resistance in A.baumannii is found in Xinjiang.The positive rate of qacE△1-sul1 is high.Strengthening epidemiology surveillance of resistance carried by integron-carrying gene is important.
