OBJECTIVE: To investigate the prevalence of Echinococcus infections in wild carnivores in Serthar County, Sichuan Province, so as to provide insights into echinococcosis control in local areas. METHODS: Stool samples were collected from wild carnivores in Serthar County, Sichuan Province in May 2021, and the host sources of stool samples and Echinococcus infections were identified using PCR assays. The prevalence of E. multilocularis, E. granulosus and E. shiquicus infections was estimated in different hosts. RESULTS: A total of 583 stool samples were collected from wild carnivores, including 147 stool samples from fox, 154 from wolf, 227 from wild dogs and 11 from lynx. The overall prevalence of E. multilocularis, E. granulosus and E. shiquicus infections was 5.68%, 0.19% and 14.20% in canine stool samples, and no E. granulosus infection was detected in fox stool samples, while the prevalence of E. multilocularis and E. shiquicus infections was 0.68% and 47.62% in fox stool samples (χ² = 88.41, P < 0.001). No E. granulosus or E. shiquicus infection was detected in wolf stool samples, and the prevalence of E. multilocularis infection was 10.39% in wolf stool samples. The prevalence of E. multilocularis, E. granulosus and E. shiquicus infections was 5.73%, 0.44% and 2.20% in canine stool samples (χ² = 12.13, P < 0.01). In addition, the prevalence of E. multilocularis infections was significantly higher in wolf stool samples than in canine and fox stool samples (χ² = 13.23, P < 0.01), and the prevalence of E. shiquicus infections was significantly higher in fox stool samples than in canine and wolf stool samples (χ² = 187.01, P < 0.001). No Echinococcus infection was identified in 11 lynx stool samples. CONCLUSIONS The prevalence of Echinococcus infections is high in wild canines in Serthar County, Sichuan Province. Wolf, wild dog and fox all participate in the wild life cycle of E. multilocularis in Serthar County, and wolf and wild dogs may play a more important role.

The purpose of this study was to investigate the feasibility and therapeutic effects of a novel concept hand rehabilitation device based on magnetics for subacute stroke patients with hand motor impairment. We developed an end effector type device that can induce various movements of the fingers in accordance with a magnetic field direction using electromagnets and permanent magnets. Subacute stroke patients with hand motor impairments were recruited and divided into two rehabilitation groups. Conventional rehabilitation therapies were also conducted equally in both groups. Active-assisted training of the affected hand was additionally administered for 30 minutes per day for 4 weeks using the developed equipment in the intervention group. Hand motor function and the activities of daily living were evaluated before and after the intervention. The Manual Function Test score significantly increased in the intervention group after 4 weeks of treatment (p = 0.039), and there was a significant difference in the degree of improvement between the two groups (p = 0.016). The scores of the motor Fugl-Meyer Assessment of the upper limb, the Wolf Motor Function Test score and time, and the motor Functional Independence Measure also improved in both groups (all p < 0.05). In addition, the patients in the intervention group showed greater improvements in these outcome measures than those in the control group did (all p < 0.05). An adjuvant rehabilitation therapy using a magnetic based device can be helpful to improve the hand motor function and activities of daily life in subacute stroke patients.

Systemic lupus erythematous (SLE) is a systemic autoimmune disease with multi-organ inflammation caused by the production of pathogenic autoantibodies and immune complexes reflecting a global loss of tolerance. Lupus nephritis (LN) is present in approximately 60% of SLE patients and is considered a major predictor of a poor prognosis. To date, many studies utilizing genomics, transcriptomics, epigenetics, metabolomics, and microbiome have been conducted on a range of animal models and lupus patients to understand the pathogenesis of SLE and LN. Collectively, these studies support the concept that LN is caused by increased cell death, which has not been properly dealt with; abnormal innate immunity; hyperactive adaptive immunity; and genetic variants triggered by a range of environmental factors. This review summarizes the results from studies that contributed strongly to elucidating the pathogenesis of SLE and LN, highlighting the immunological and non-immunological mechanisms.

OBJECTIVE: To Investigate the synergic effects of short-term constraint-induced movement therapy (CIMT) and visual biofeedback training (VBT) in subacute stroke patients. METHODS: Thirty-two subacute stroke patients were enrolled and randomly assigned to one of three groups: short-term CIMT with VBT, VBT only, and control groups. We applied CIMT for an hour daily during VBT instead of the ordinary restraint time, referred to as 'short-term' CIMT. Short-term CIMT with VBT group received simultaneous VBT with CIMT, whereas the VBT the only group received VBT without CIMT for an hour a day for 2 weeks. The control group received conventional occupational therapy (OT) alone. Patients underwent the Purdue Pegboard Test, the JAMAR grip strength test, the Wolf Motor Function Test, the Fugl-Meyer Assessment (upper extremity), Motricity index and the Korean version of Modified Barthel Index test to evaluate motor functions of the hemiplegic upper limb at baseline, post-treatment, and 2 weeks after treatment. RESULTS: No significant differences were observed between short-term CIMT with VBT and VBT only groups. Both groups showed significantly higher scores compared to the control group in the WMFT and FMA tests. However, the short-term CIMT with VBT group showed significant improvement (p<0.05) compared with the control group in both grasp and pad pinch at post-treatment and 2 weeks after treatment while the VBT only group did not. CONCLUSION: Short-term CIMT with VBT group did not show significant improvement of hemiplegic upper limb function of subacute stroke patients, compared to VBT only group. Larger sample sizes and different restraint times would be needed to clarify the effect.

Primary meningeal hemangiopericytoma (HPC) is a rare, aggressive dura based tumor that remarkably mimics a meningioma clinically and radiologically. Its occurrence within the cerebellopontine angle (CPA) is exceptional, and establishing the exact diagnosis is of the utmost importance since total resection remains the cornerstone of treatment. A 42-year-old man presented with a three-month history of progressively worsening vertigo and difficulty in walking. On admission, his neurological examination revealed a right peripheral facial palsy, right abducens palsy and left hemiparesis, suggesting the diagnosis of Millard-Gubler syndrome. Computed tomography and magnetic resonance imaging demonstrated a homogeneously enhancing dura based lesion of the right CPA causing major brain stem compression. There was no widening of the ipsilateral internal auditory canal. A standard retrosigmoid craniotomy was performed to access the right CPA. Exposure of the lesion revealed a well-encapsulated, gray, fibrous lesion, which appeared to originate from the tentorium. Gross total resection was achieved and confirmed radiologically. The microscopic features and the immunohistochemical profile confirmed the diagnosis of a HPC, and adjuvant radiation therapy was administered. Ten years later, the patient presented with a severe neurological deficit due to a local recurrence, but at that time refused any second intervention. He died three months later. HPC can locate within the CPA and present as a Millard-Gubler syndrome. The diagnosis should be kept in mind in case of a CPA dura based tumor. Radical surgery plus radiation therapy can maximize the recurrence-free survival and close follow-up remains mandatory to spot recurrences early.

OBJECTIVE: To compare the pain and functional improvement of suprascapular nerve block (SSNB) and intra-articular hyaluronic acid (HA) injection in post-stroke patients with hemiplegic shoulder pain. METHOD: In total, 24 stroke patients were randomly assigned in the SSNB group (n = 12) or the HA group (n = 12). Ultrasound (US) guided SSNB with 10 cc of 1% lidocaine and US guided intra-articular injection with 2 cc of HA was done in each group 3 times weekly. Visual analogue scale (VAS), Fugl-Meyer scale (FMS), Wolf motor function test (WMFT), Brunnstrom stage, modified Ashworth scale (MAS), range of motion (ROM) of shoulder joint and brief pain inventory (BPI) concerning the interference of patient's function (activity, mood, walking, work, relationship, sleep and enjoy) were assessed before the injection, one week and four weeks after first injection. RESULTS: Both groups showed significant improvements in pain assessed by VAS, but the changes between the two groups were not significantly different. There were no significant improvements and did not show any significant differences between the two groups in FMS, WMFT, Brunnstrom stage, MAS and ROM of shoulder joint. On several items of the BPI concerning the interference of patient's function (activity, mood, work, and enjoy), only SSNB group showed significant improvement, even though the differences between the two groups were not significant. CONCLUSION: Both SSNB and intra-articular HA injection were safe and effective in pain and functional ability in hemiplegic shoulder pain. But comparing the interference of patient's function caused by pain, only SSNB showed significant improvement.

OBJECTIVE: To evaluate the effectiveness of constraint-induced movement therapy (CIMT) and combined mirror therapy for inpatient rehabilitation of the patients with subacute stroke. METHODS: Twenty-six patients with subacute stroke were enrolled and randomly divided into three groups: CIMT combined with mirror therapy group, CIMT only group, and control group. Two weeks of CIMT for 6 hours a day with or without mirror therapy for 30 minutes a day were performed under supervision. All groups received conventional occupational therapy for 40 minutes a day for the same period. The CIMT only group and control group also received additional self-exercise to substitute for mirror therapy. The box and block test, 9-hole Pegboard test, grip strength, Brunnstrom stage, Wolf motor function test, Fugl-Meyer assessment, and the Korean version of Modified Barthel Index were performed prior to and two weeks after the treatment. RESULTS: After two weeks of treatment, the CIMT groups with and without mirror therapy showed higher improvement (p<0.05) than the control group, in most of functional assessments for hemiplegic upper extremity. The CIMT combined with mirror therapy group showed higher improvement than CIMT only group in box and block test, 9-hole Pegboard test, and grip strength, which represent fine motor functions of the upper extremity. CONCLUSION: The short-term CIMT combined with mirror therapy group showed more improvement compared to CIMT only group and control group, in the fine motor functions of hemiplegic upper extremity for the patients with subacute stroke.

Recently, we reported the three wolves cloning with normal karyotype from somatic cells of endangered male gray wolves (Canis lupus), but one wolf had female external genitalia. In this study, we conducted further clinical, histological, and genetic analyses. This cloned wolf had a normal uterus but developed ovotestis. Through molecular analysis of the SRY gene, a mutation in the coding sequence of SRY gene could be excluded as a cause of intersexuality. This is the first report of a cloned wolf with a 78, XY ovotesticular disorder affecting sexual development characterized by bilateral ovotestes.

OBJECTIVES: Osteoclast differentiation and bone resorption are considered a potential therapeutic target to the treatment of erosive bone diseases, including osteoporosis and rheumatoid arthritis. Poria cocos Wolf (PCW), commonly used herbal medicine, has previously been reported to induce anti-inflammatory effect and anti-cancer effect, and to modulate immunologic responses. However, the effects of PCW on osteoclasts, and its detailed mechanisms are not proven. Therefore, we examined the inhibitory mechanism of PCW on osteoclast differentiation and bone resorption. MATERIALS AND METHODS: To analyze the effects of PCW on osteoclast differentiation, we examined osteoclast differentiation in bone marrow macrophages (BMMs) treated with or without of PCW by TRAP staining. The expression of c-Fos, NFATc1, TRAP and OSCAR mRNA was determined by RT-PCR and the protein levels of c-Fos, NFATc1, p38, ERK, JNK, Akt and IkappaB were assessed by western blot. Also, we evaluated the effect of PCW on bone resorption using hydroxyapatite plate. RESULTS: PCW significantly inhibited RANKL-mediated osteoclast differentiation without any evidence of cytotoxicity. We founded that PCW strongly inhibited RANKL-induced osteoclast formation when added during the early stage of cultures, suggesting that PCW acts on osteoclast precursors to inhibit RANKL/RANK signaling. Among the RANK signaling pathways, PCW inhibited the phosphorylation of p38 and JNK, also inhibited RANKL-induced expression of c-Fos, NFATc1, TRAP and OSCAR. In addition, PCW suppressed the bone resorption of mature osteoclasts. CONCLUSIONS: These findings suggest that PCW may be a potential novel drug for bone disorders by targeting the differentiation of osteoclasts as well as their functions.
