Objective:To evaluate the effects of high-frequency repetitive transcranial magnetic stimulation(HF-rTMS)of different intensities on the recovery of upper limb motor dysfunction in patients during the early recovery stage of cerebral infarction. Method:Sixty patients with cerebral infarction at early recovery stage were randomly divided into the HF-rT-MS 80％RMT group,the HF-rTMS 100％RMT group and the sham stimulation group,with 20 patients in each group.All three groups were also given basic treatment(medication and routine rehabilitation training).Be-fore and after 4 weeks treatment,the Fugl-Meyer Assessment-Upper extremity(FMA-UE)and Modified Barth-el Index(MBI),the latency of motor evoked potential(MEP).central motor conduction time(CMCT)and blood flow velocity of the ipsilateral middle cerebral artery(MCA)were recorded. Result:Before treatment,there were no significant differences in FMA-UE score,MBI score,MEP latency,CMCT and the blood flow velocity of MCA among the three groups(P＞0.05).After four weeks of treatment,the above indicators of the three groups were significantly higher than those before treatment(P＜0.05).More-over,the improvement of the indicators in the 80％RMT group and 100％RMT group were significantly higher than those in the sham stimulation group(P＜0.05).Except for MBI score,the improvement in all indicators in the 100％RMT group were the most significant(P＜0.05). Conclusion:HF-rTMS can improve upper limb function and activity of daily living during the early recovery stage of cerebral infarction.Compared with 80％RMT,100％RMT HF-rTMS has more advantages in improv-ing function,motor nerve excitability and cerebral blood flow.

Objective:To analyze the clinical characteristics of children with systemic lupus erythematosus (SLE) combined with thrombotic microangiopathy (TMA), and clarify the clinical outcomes and related risk factors of pediatric patients through their treatment and follow-up.Methods:This was a single-center retrospective case-control study. Children diagnosed with SLE combined with TMA between January 2017 and January 2023 at Beijing Children′s Hospital, Capital Medical University, were selected as the TMA group, and SLE children without TMA were selected as the control group.According to the prognosis, children in the TMA group were further divided into the good prognosis group and the poor prognosis group.The data of the children were collected, including age, gender, SLE disease activity, clinical presentations at the time of diagnosis and at the time of thrombosis, laboratory examinations, treatment strategies, prognosis, and follow-up results.The chi-square test and Z-test were used for comparison of count data.The t-test was used for comparison of metrological pairing data.The Fisher′s exact test was used to compare the differences between the 2 groups in categorical variables.The univariate Logistic regression was used to analyze the risk factors of poor prognosis. Results:There were 29 cases in the TMA group, and the incidence of TMA accounted for 2.53% of SLE patients; 33 cases were in the control group.The age at diagnosis of TMA was 13 years and 5 months (ranging from 9 years, 1 month and 5 days to 17 years and 4 months).The common clinical manifestations in order of prevalence were renal involvement (28 cases, 96.55%), hematologic involvement (26 cases, 89.66%), serous effusion (17 cases, 58.62%), rash (13 cases, 44.82%), and neurologic involvement (12 cases, 41.38%).Pleurisy or pericarditis, renal involvement and neurological involvement occurred more often in the TMA group than in the control group (17 cases vs.3 cases, 28 cases vs.10 cases, 12 cases vs.3 cases), and the TMA group showed less facial rash and arthritis than the control group (13 cases vs.25 cases, 4 cases vs.17 cases), and the differences were statistically significant (all P<0.05).The Systemic Lupus Erythematosus Disease Activity Index score in the TMA group [(24.14±9.42) scores] was significantly higher than that in the control group [(10.18±9.42) scores], and the difference was statistically significant ( t=3.233, P<0.05).The hemoglobin level, platelet count, and complement C3 level of the children in the TMA group were significantly lower than those in the control group, whereas the double stranded DNA antibody, lactate dehydrogenase, D-dimer, urea, creatinine, ferritin level, and urine protein quantitation were significantly higher than those in the control group, and the differences were statistically significant (all P<0.05).In the TMA group, 5 cases had decreased ADAMTS13 activity, and 5 cases had significantly increased complement C5b9.A total of 15 cases (51.72%) in the TMA group underwent renal biopsy, and 13 of them had combined renal TMA.In the TMA group, 28 patients (96.6%) received hormone therapy, 17 patients received plasma exchange, and 12 patients were treated with immunosuppressants and biologics; 19 patients (65.5%) improved, and 10 patients (34.5%) gave up the treatment due to deterioration of the disease.The urea level and peripheral blood fragmented erythrocyte rate in the good prognosis group were significantly lower than those in the poor prognosis group [(13.18±4.39) mmol/L vs.(21.16±10.14) mmol/L, t=2.975, P=0.006; 8/17 (47.06%) vs.7/7 (100%), χ2=5.929, P=0.015].The univariate Logistic regression analysis showed that the fragmented erythrocyte, ADAMTS13 activity and urea were the independent risk factors for poor prognosis (all P<0.05). Conclusions:SLE patients with moderate-to-severe disease activity, especially children with hemolytic anemia, thrombocytopenia, and renal dysfunction as prominent manifestations, should be alert to the risk of TMA.Early diagnosis and treatment are crucial.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

Objective To evaluate the accuracies of two-dimensional ultrasound(2D-US)and three-dimensional ultrasound virtual organ computer-aided analysis(3D-VOCAL)in measuring uterine myoma volume(UMV).Methods Forty-five patients who underwent surgical treatment for uterine myoma at Longyan First Hospital,Fujian Medical University from October 2022 to April 2023 were selected.Preoperative measurements of UMV were performed using 2D-US and 3D-VOCAL,and the measurement results were compared with the actual UMV after surgical resection to assess the accuracies and repeatabilities of the two ultrasound techniques in measuring UMV.Results The UMV measurement consistency of 3D-VOCAL(ICC=0.992)was higher than that of 2D-US(ICC=0.976),and the ICC values of 3D-VOCAL were higher than those of 2D-US in UM of different sizes(all P<0.001).Statistically significant differences among 2D-US,3D-VOCAL and postoperative measurement results was found in UM with a maximum diameter≥8 cm(P<0.05),but not in UMV and UM with a maximum diameter<8 cm(P>0.05),and the further analysis showed that in UM with a maximum diameter≥8 cm,the UMV measured by 2D-US differed from postoperative measurement results(P<0.05).The differences between 3D-VOCAL measurement results and postoperative measurement results were trivial(P>0.05).There were greater intra-and interobserver agreements by 3D-VOCAL than 2D-US in UMV measurement.Conclusion 3D-VOCAL which is superior to 2D-US in preoperative UMV measurement is a simple,efficient,and reliable method,and it can provide theoretical bases for clinical follow-up.

Objective:To identify the influencing factors of postoperative nausea and vomiting (PONV) in the patients undergoing egg retrieval with general anesthesia for in vitro fertilization-embryo transfer (IVF-ET).Methods:This was a case-control study. Medical records from IVF-ET patients undergoing egg retrieval with general anesthesia in the Center for Reproductive Medicine in our hospital from November to December 2020 were retrospectively collected, 52 patients with PONV were identified (group PONV), and 252 patients without PONV were selected as control group (group C). Univariate analysis was performed on the suspicious influencing factors, and the factors with statistically significant differences were included in the logistic regression analysis model to identify the influencing factors of PONV.Results:Compared with group C, statistically significant differences were found in the number of eggs, anesthesia time, and the proportion of PONV history and/or motion sickness history in group PONV ( P<0.05). The results of multivariate logistic regression analysis showed that a large number of eggs, long anesthesia time, and a high proportion of PONV history and/or motion sickness history were independent risk factors for PONV. Conclusions:A large number of eggs, long anesthesia time, and a high proportion of PONV history and/or motion sickness history are independent risk factors for PONV in IVF-ET patients undergoing egg retrieval with general anesthesia.

Objective To observe the effect of abdominal acupuncture in treating allergic rhinitis(AR).Methods Twenty-seven AR patients who attended Fangshan Hospital,Beijing University of Chinese Medicine from August to October 2022 were selected.They were divided into treatment group(15 cases)and control group(12 cases)according to randomized numerical table method.The treatment group received abdominal acupuncture.The control group at the same point was used one-time sterile cannula acupuncture to simulate acupuncture,but no needle was inserted into the acupoint.Two groups were treated,3 times a week for 4 weeks.The visual analogue scale(VAS),rhinoconjunctivitis quality of life questionnaire(RQLQ),Pittsburgh sleep quality index(PSQI)scores,and the histamine(HIS),leukotriene D4(LTD4),immunoglobulin E(IgE)levels were compared between two groups before and after treatment.Results At each time point after treatment,the VAS,RQLQ,PSQI scores and HIS,LTD4,IgE levels of patients in treatment group were significantly lower than those before treatment(P<0.05).There were no statistically significant differences in VAS,RQLQ,and PSQI scores,the HIS,LTD4,and IgE levels after 2-week treatment in both groups(P>0.05).After 4-week treatment and follow-up 4-week,the VAS,RQLQ,and PSQI scores,the HIS,and LTD4 levels in treatment group were significantly lower than those in control group(P<0.05).Conclusion Abdominal acupuncture has good therapeutic effect on AR and significantly improves life quality of the patients,which can reduce the levels of HIS,LTD4 and IgE.The therapy is worthy of clinical application.

Objective:To explore the surgical procedure and effect of reconstruction of soft tissue defects in the distal segment of dorsal finger with a perforator(joint branch) flap of proper palmar digital artery combined with a dorsal metacarpal artery flap.Methods:From January 2019 to June 2022, 9 patients with soft tissue defects in distal dorsal finger, mostly with avulsion at the extensor tendon insertion point, were treated in Department of Hand and Foot Microsurgery, the Affiliated Hospital of Qingdao University. The defect areas were 1.0 cm×1.0 cm-2.5 cm×2.0 cm. Steel wires were used to reconstruct the extensor tendon insertion point. The defects were reconstructed by a perforator(joint) flap of proximal phalanx artery and a dorsal metacarpal artery flap was used to repair the donor site for proximal flap. Postoperative follow-up and evaluation included flap survival, flap appearance, scars and function of interphalangeal and metacarpophalangeal joints, through outpatient clinical, WeChat and so on.Results:The flap of digital artery perforator (joint branch) and the fasciocutaneous flap of dorsal metacarpal artery all survived. One flap of the digital artery perforator(joint branch) appeared purple and tension blisters after surgery. The stitches of the pedicle of the flap were partially dismantled at 36-48 hours after surgery. The flap was then turned to ruddy in colour 7 days after surgery. The wounds of the distal finger joint and nail bed healed well without redness and infection. The postoperative follow-up lasted for 5 to 12 months, 9 months in average. The appearance, colour and texture of the skin at distal finger were similar to those at the dorsal proximal finger and dorsal palm. Sensation recovered well, all flaps exceeding S 3. The two-point resolution (TPD) was 8-10 mm, with an average of 9.5 mm. According to the Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, 5 cases were in excellent and 4 in good. Conclusion:The perforator(joint branch) flap of proper palmar digital artery combined with a dorsal metacarpal artery flap is simple and safe treatment. It has a fast functional recovery with an aesthetic appearance in reconstruction of the soft tissue defect in distal segment of dorsal finger.

Objective:To investigate the clinical effect of bilateral anteriolateral thigh perforator flaps (ALTPF) pedicled with descending branch of lateral circumflex femoral artery in series on reconstruction of large soft tissue defects in lower limbs.Methods:A total of 9 patients with large soft tissue defects in lower limbs were selected in the study. The patients were 6 males and 3 females aged between 18 and 57 years old. They were treated in the Department of Hand and Foot Microsurgery, the Affiliated Hospital of Qingdao University from June 2018 to January 2023. Causes of injury: 4 of traffic accident, 2 of crushing, 2 of falling from height and 1 of explosion. Five patients had combined defects in dorsal feet and 4 with tibia fractures and anterior-and-posterior-tibial soft tissue defects. All affected limbs had tissue necroses and infections in various degrees. Deep tissue defects such as tendons, nerves, bones and joints or orthopaedic implants were exposed. The areas of soft tissue defects were 30 cm×14 cm-42 cm×14 cm. All the defects were reconstructed by the bilateral ALTPF pedicled with descending branch of lateral circumflex femoral artery in series. The size of proximal flaps was 25 cm×8 cm-33 cm×13 cm and 20 cm×7 cm-29 cm×13 cm for the distal flaps. Scheduled postoperative follow-ups were conducted to observe the survival of the transferred flaps and functional recovery of calfs and feet. Sensory recovery was assessed against British Medical Research Council (BMRC) criteria. Puno scoring was used to assess the functional recovery and the effectiveness of treatment.Results:All flaps survived and the donor sites healed well. One patient developed vascular compromise within 24 hours after surgery, but it was rectified after timely surgical exploration, however it left with a small area of necrosis at distal end of the flap. The necrosis and wound healed after skin grafting in stage-two surgery. Postoperative follow-up lasted for 8.3 months in average. Two patients underwent flap thinning in stage-two surgery due to bloating appearance, 2 patients had slightly bloated flaps at the calfs, and the rest of 5 patients had satisfactory flap appearance. Two patients received nerve reconstruction by anastomosis of the lateral femoral cutaneous nerves. At the final follow-up, the sensory recovery in 9 patients achieved S 2-S 3+ according to BMRC. The average Puno score achieved 88.36 point±5.36 point, of which 4 patients in excellent, 3 in good and 2 in fair. Conclusion:The use of bilateral ALTPF pedicled with descending branch of lateral circumflex femoral artery in series to reconstruct a large soft tissue defect in lower extremity has a good clinical value, and it has become one of the effective methods.

  Objective  To study the demographic and clinical characteristics, correlation of genotype and phenotype and treatment of Blau syndrome to facilitate early diagnosis and timely treatment of Blau syndrome.  Methods  Seventy-two patients with Blau syndrome from 11 centers from May 2006 to April 2022 were retrospectively analyzed, and their general information, clinical data, laboratory examination and treatment medication were collected.  Results  The distribution of patients with Blau syndrome was uniform in geographical north and south of China, and there was no obvious gender bias. The mean age of onset was (14.30±12.81) months, and the age of diagnosis was (55.18±36.22) months. 35% of patients with Blau syndrome happened before 1 year old, and all patients developed before 5 years old. 87.50% (63/72) had granulomatous arthritis, 65.28% (47/72) had rash, 36.11% (26/72) had ocular involvement, 27.78% (20/72) had fever, and 15.28% (11/72) had pulmonary involvement. Arthritic manifestations of Blau syndrome were most at risk, followed by rash, ocular involvement, and fever.The first 25 months of the disease, the risk of developing a rash was the greatest. The risk of developing arthritis was the greatest between 25 months and 84 months. The main mutations were p.R334Q and p.R334W, and patients with p.R334Q mutation had relatively high incidence of fever (35.71%[5/14] vs. 14.29%[1/7], P=0.43) and ocular involvement (42.86%[6/14]vs. 28.57%[2/7], P=0.51). There was a relatively high incidence of rash (85.71%[6/7] vs. 64.29%[9/14], P=0.59) in patients with the p.R334W mutation. Forty-five patients(62.50%)were treated with a combina-tion of glucocorticoid and methotrexate. Twenty-two patients were treated with tumor necrosis factor antagonist in addition to glucocorticoid and methotrexate.  Conclusions  The risk of different clinical manifestations of Blau syndrome from high to low was arthritis, followed by rash, ocular involvement and fever. The main treatment was glucocorticoid combined with methotrexate, to which biological agents could be added.
