Objective To investigate the role of IgG determination in diagnosis of early renal damage in children with Henoch-schonlein purpura(HSP). Methods Urine IgG was determined in 188 children with HSP (HSP group), 99 patients with Henoch-schonlein purpura nephritis (HSPN group) and 26 healthy controls (healthy control group). Simultaneously, qualitative detection of urine protein was carried out in HSP group. Results The abnormality rate of urine IgG was significantly higher than that of urine protein in HSP group (P<0. 05). The level of urine IgG was significantly higher in HSP group than that in healthy control group (P<0. 05), while the level of urine IgG in group than that in HSP group (P<0. 05). Conclusion Urine IgG determination is simple and nonin-vasive, which if high clinical value in diagnosis of early renal damage in children with Henoch-schonlein purpura(HSP).

Objective:
This study aimed to elucidate the hand function recovery capacity of degenerative cervical myelopathy (DCM) patients with different severities of hand dexterity impairment.
Methods:
Hand functional outcome measures such as the 10-second grip and release (10s-G&R) test, modified Japanese Orthopaedic Association (mJOA) upper extremity score and Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) upper extremity function were collected before surgery and at the 1-year follow-up. A total of 102 DCM patients were categorized into mild, moderate and severe group based on the preoperative 10s-G&R test result. Hand functional parameters were compared across the 3 groups. Multivariate linear regression was conducted to explore predictive factors. Receiver operating characteristic curve analysis was performed to assess the predictive efficacy of the preoperative 10s-G&R test and establish the cutoff value for incomplete recovery of hand dexterity.
Results:
At the 1-year follow-up, significant improvements were observed in all hand functional parameters across all 3 groups. However, the incomplete recovery rates of the mild, moderate, severe groups were 26.67%, 46.88%, and 57.50%, respectively (p < 0.05). Multivariate regression revealed that preoperative 10s-G&R test result, age, Hoffmann sign, duration of symptom, and mJOA Upper score serve as significant predictors for postoperative 10s-G&R test outcomes. Patients with a preoperative 10s-G&R test < 15 cycles have a 1.9 times higher risk of incomplete recovery of hand function (p = 0.005).
Conclusion
Most patients, regardless of their preoperative hand function, exhibit potential for improvement in hand dexterity. However, worse initial hand dexterity correlates with poorer outcomes. Surgical treatment is recommended before the 10s-G&R test drops below 15 cycles.

Objective: To evaluate the therapeutic effect and security of Buyang Huanwu decoction in treatment of the ischemic stroke recovery. Methods: We retrieved the relevant articles of random and semi- random control trials in treating ischemic stroke recovery using Buyang Huanwu decoction, published in China National Knowledge Infrastructure (CNKI), the Wanfang Data, the Weipu Information Resources System, the Chinese Biomedical Literature Database (CBM), Cochrane Library, PUBMED and MEDLINE from the date of establishment until to March 2018. The quality of studies was evaluated according to the Cochrane Reviewers?? handbook 5.1, and the study was carried out using Cochrane system assessment methods. Statistical analysis was performed with Rev Man 5.3. Results: Altogether 39 studies and 3539 cases of ischemic stroke recovery were enrolled. In terms of clinical efficacy, the difference between Buyang Huanwu Decoction and Western Medicine conventional therapy in the treatment of ischemic stroke was significantly different from that of conventional western medicine therapy [RR =1.26, 95%CI (1.20, 1.31), Z =10.05, P < 0.00001], and the difference between Buyang Huanwu Decoction and other Chinese patent medicines was statistically significant [RR =1.12, 95%CI(1.06, 1.19), Z =3.82, P =0.0001]; neurological deficit NIHSS score [MD =-2.55, 95%CI (-3.10, -2.01), Z =9.20, P < 0.00001]; clinical neurological deficit score (CSS) [MD =-3.85, 95%CI (-5.21, -2.50), Z =5.56, P < 0.00001]; limb motor function score (FMA) [MD =6.10, 95%CI (1.19, 11.01), Z =2.43, P =0.01]; Barthel Index of Daily Living Activity Scale [MD =9.09, 95%CI (6.95, 11.23), Z =8.33, P < 0.00001]; In terms of improving blood rheology index, serum peroxide lipid (LPO), serum superoxide dismutase (SOD) and other biochemical indicators, due to the small number of studies, it may have a certain effect. Most studies did not report adverse reactions. Conclusion: Based on the existing clinical evidence, combination of Buyang Huanwu decoction and western medicine has higher clinical efficacy than western medicine alone for the ischemic stroke recovery. Due to the limited methodological quality of the included studies, more high- quality RCTs with large scale are needed to increase the strength of the above evidence.

Objective:
Hand clumsiness and reduced hand dexterity can signal early signs of degenerative cervical myelopathy (DCM). While the 10-second grip and release (10-s G&R) test is a common clinical tool for evaluating hand function, a more accessible method is warranted. This study explores the use of deep learning-enhanced hand grip and release test (DL-HGRT) for predicting DCM and evaluates its capability to reduce the duration of the 10-s G&R test.
Methods:
The retrospective study included 508 DCM patients and 1,194 control subjects. Propensity score matching (PSM) was utilized to minimize the confounding effects related to age and sex. Videos of the 10-s G&R test were captured using a smartphone application. The 3D-MobileNetV2 was utilized for analysis, generating a series of parameters. Additionally, receiver operating characteristic curves were employed to assess the performance of the 10-s G&R test in predicting DCM and to evaluate the effectiveness of a shortened testing duration.
Results:
Patients with DCM exhibited impairments in most 10-s G&R test parameters. Before PSM, the number of cycles achieved the best diagnostic performance (area under the curve [AUC], 0.85; sensitivity, 80.12%; specificity, 74.29% at 20 cycles), followed by average grip time. Following PSM for age and gender, the AUC remained above 0.80. The average grip time achieved the highest AUC of 0.83 after 6 seconds, plateauing with no significant improvement in extending the duration to 10 seconds, indicating that 6 seconds is an adequate timeframe to efficiently evaluate hand motor dysfunction in DCM based on DL-HGRT.
Conclusion
DL-HGRT demonstrates potential as a promising supplementary tool for predicting DCM. Notably, a testing duration of 6 seconds appears to be sufficient for accurate assessment, enhancing the test more feasible and practical without compromising diagnostic performance.
