Objective To observe the effects of early rehabilitation on the motor function of post-stroke hemiplegic patients treated with intravenous thrombolysis.Methods Thirty-six post-stroke hemiplegic patients after intravenous thrombolysis with rtPA were recruited in this study.They were randomly divided into the early rehabilitation group (with the course less than three days) and the control group (with the course between three and seven days),18 cases in each group.Both group received a two-week rehabilitation programme.They were assessed using the Fugl-Meyer assessment (FMA) of up extremity,FMA of lower extremity and ADL score (modified Barthel index,MBI) before and after treatment,as well as at the 3rd month after treatment (during the following-up).Results After treatment and at the following-up,FMA scores of up extremity,FMA scores of lower extremity and MBI scores had improved significantly compared with before treatment in both groups.Furthermore,after treatment,in the early rehabilitation group the average FMA score of lower extremity and MBI score reached (23.33 ± 4.37) and (56.11 ± 22.27) respectively,significantly higher than those of the control group [(17.06 ± 4.70) and (40.00 ± 15.81) respectively].Conclusion Early rehabilitation contributes to short-term recovery of lower extremity motor function and ability in the activities of daily living in post-stroke hemiplegic patients after intravenous thrombolysis.

Mild cognitive impairment (MCI) is a clinical syndrome characterized by the onset and evolution of cognitive impairments, often considered a transitional stage to Alzheimer’s disease (AD). The genetic traits of MCI patients who experience a rapid progression to AD can enhance early diagnosis capabilities and facilitate drug discovery for AD. While a genome-wide association study (GWAS) is a standard tool for identifying single nucleotide polymorphisms (SNPs) related to a disease, it fails to detect SNPs with small effect sizes due to stringent control for multiple testing. Additionally, the method does not consider the group structures of SNPs, such as genes or linkage disequilibrium blocks, which can provide valuable insights into the genetic architecture. To address the limitations, we propose a Bayesian bi-level variable selection method that detects SNPs associated with time of conversion from MCI to AD. Our approach integrates group inclusion indicators into an accelerated failure time model to identify important SNP groups. Additionally, we employ data augmentation techniques to impute censored time values using a predictive posterior. We adapt Dirichlet-Laplace shrinkage priors to incorporate the group structure for SNP-level variable selection. In the simulation study, our method outperformed other competing methods regarding variable selection. The analysis of Alzheimer’s Disease Neuroimaging Initiative (ADNI) data revealed several genes directly or indirectly related to AD, whereas a classical GWAS did not identify any significant SNPs.

Objective To explore the effect of motor imagery therapy combined with balance evaluation and training on balance and performance in the activities of daily living (ADL) after an initial stroke.Methods A total of 48 stroke patients were randomly divided into a control group (n =25) and an observation group (n =23).All of the patients in both groups were given routine rehabilitation and balance training.In addition,the patients of the observation group were given motor imagery therapy.Balance and ADL performance were assessed before the training and 2 weeks and 4 weeks after the training began.The subjects' balance was analyzed using the center of the gravity shift index,shift angle,total length of shift trace and envelope area using a balance evaluation system and the balance subscale of the Fugl-Meyer assessment (FM-B).Performance in the activities of daily living was assessed using the modified Barthel index (MBI).Results Before the training there were no significant differences between the two groups in terms of any of the measurements.After 2 weeks and 4 weeks of training,all the measurements in both groups were significantly better than those before training,but the improvement of the observation group was significandy greater than that of the control group (except in terms of the MBI).Conclusion Motor imagery therapy combined with balance training can distinctly improve the balance and activities of daily living of stroke survivors.The combination is worthy of application in the clinic.

ObjectiveTo compare the liver histopathological features of drug-induced liver injury (DILI) caused by Chinese herbal medicine (HM) and that caused by Western medicine (WM), and to investigate the pathological features of HM-DILI. MethodsA total of 50 patients with drug-induced liver injury(DILI) who were diagnosed and treated in Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from March 2014 to June 2019. All the patients with DILI were enrolled and divided into HM-DILI group and WM-DILI group. A retrospective analysis was performed for the clinical features and the pathological features of the two groups, including the clinical type of DILI, severity of liver injury, and liver histopathological features, especially location and grade of liver inflammation, type and degree of steatosis, and iron deposition. The t test and Mann-Whitney U test was used for comparison of continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups; the Mann-Whitney U test was used for comparison of ranked data. ResultsOf all 50 patients, 20 (40.0%) had HM-DILI and 30 (60%) had WM-DILI. There were no significant differences in sex, age, course of disease, and biochemical parameters of liver function between the two groups (all P>0.05). The main clinical types of the two groups were hepatocellular injury type and the degree of injury which was mainly grade l, and there were no significant differences in the clinical type of DILI and the severity of liver injury between the two groups (both P>0.05). As for liver histopathological features, both groups had varying degrees of focal necrosis of hepatocytes, steatosis (microvesicular, macrovesicular, and mixed), and fibrous tissue proliferation at the portal area, and compared with the WM-DILI group, the HM-DILI group had significantly greater lymphocyte/plasma cell infiltration in the portal area (χ2=3.860, P<0.05) and iron deposition in Kupffer cells (χ2=4787, P<0.05). ConclusionThere are no significant differences in clinical manifestations between HM-DILI and WM-DILI, but patients with HM-DILI have more obvious inflammation in the portal area and iron deposition in Kupffer cells than those with WM-DILI.

Objective:
To analyze the clinicopathological features and differential diagnosis of interdigitating dendritic cell sarcoma (IDCS).
Methods:
The clinical pathological features of 7 IDCS were analyzed. Among them, the follow-up results of 6 cases were available.
Results:
Among the 7 IDCS patients, 4 cases were male and 3 were female. The age of the patients ranged from 26 to 69 years.Three cases were originated from lymph nodes and 4 cases were originated from skin, stomach, adrenal gland and mesentery, respectively. Microscopically, the tumor cells presented as fascicular and storiform proliferation and infiltrated by lymphocytes. The tumor cells were short-spindle or ovoid, with indistinct border of cytoplasm. The immunohistochemistry results showed that tumor cells were S-100, Vim, CD68 and CD163 positive, and AE1/AE3, EMA, CD117, CD34, Desmin, SMA, CD1α, CD21, CD23, CD35, HMB45, Melan-A, MelanPan and ALK negative.The BRAF mutation and clonal rearrangement of T and B cells were not detected. Among the follow-up period of 7 IDCS patients, 3 occurred disease progressions.
Conclusions
IDCS is extremely rare with unique pathological features, and its lesion is not limited to the lymph node. The IDCS patients with extensive lesions may have worse prognose. The differential diagnosis of IDCS includes other histiocytic and dendritic cell neoplasms, malignant melanoma and soft tissue neoplasms.
