Objective To investigate the efficacy observation of transcranial direct current stimulation (tDCS)for improving the attention in patients with infarction in basal ganglia area. Methods Sixty consecutive patients with basal ganglia infarction admitted to the Department of Rehabilitation Medicine,the First Affiliated Hospital of Nanchang University from May 2015 to May 2016 were enrolled. They were randomly divided into either a control group or a test group according to the random number table (n = 30 in each group). The patients in both groups received routine rehabilitation training,and those in the test group received tDCS therapy synchronously,and the control group received the sham tDCS stimulation. The evaluations and analyses were conducted with the Montreal cognitive assessment (MoCA),d2 test of attention,and event-related potential-P300 (ERP-P300),respectively in all patients before intervention and 4 weeks after intervention,and they were compared between the groups. Results There was no significant difference before intervention between the two groups (all P > 0. 05). Compared with before intervention,the ERP-P300 latencies were reduced,the amplitudes were increased after intervention in the patients of the test group and the control group (all P < 0. 05). The MoCA total scores (the test group:22. 7 ± 2. 7 vs. 15. 5 ±
2. 4;the control group:17. 2 ±2. 5 vs. 15. 6 ±2. 3),attention dimension scores (the test group:4. 6 ± 1. 2 vs. 2. 4 ± 1. 6;the control group:3. 6 ± 1. 5 vs. 2. 5 ± 1. 5),and the total completion of d2 attention test task, total scores,and concentration degree scores (the test group:295 ± 31 vs. 250 ± 45,279 ± 38 vs. 223 ± 52, 97 ± 22 vs. 75 ± 25;the control group:276 ± 33 vs. 247 ± 45,257 ± 39 vs. 211 ± 56,84 ± 23 vs. 71 ± 24) were all increased (all P < 0. 05),and all the indexes of the test group were better than those of the control group (all P < 0. 05). Conclusion tDCS contributes to the improvement of the attention in patients with infarction in the internal capsule-basal ganglia region.

OBJECTIVETo explore the effect of Danggui Yinzi (DY) on delayed allergy in model mice with qi-blood deficiency syndrome (QBDS).
METHODSQBDS model was established in 48 Kuming mice of SPF grade by using reserpine and acetophenone hydrazine. Forty of them were then randomly divided into the model group, the loratadine group, the high dose DY group, the middle dose DY group, and the low dose DY group, 8 in each group. Another 8 in line with the same standard were recruited as a blank group. Mice in high, middle, and low dose DY groups were administered with DY concentrated solution at 60, 30, 15 g/kg by gastrogavage. Mice in the loratadine group were administered with loratadine solution at 1.66 mg/kg by gastrogavage. Equal volume of normal saline was administered to mice in the model group and the blank group by gastrogavage. All medication was given once per day for 1 successive week. Except those in the blank group, the rest mice were evenly smeared with 1% DNCB solution on the abdomen. Five days after skin allergy, 1% DNCB solution was smeared to right ear of all mice to stimulate allergic reaction. Mice in the blank group were smeared in the same way without allergenic reaction. The auricle swelling and the inhibition ratio were determined at 24 h after attack. Blood was collected from orbit and serum IgE level detected using double-antibody sandwich ELISA.
RESULTSCompared with the blank group, auricle swelling obviously increased and serum IgE level was obviously elevated in the model group (P < 0.01). Compared with the model group, auricle swelling obviously decreased and serum IgE level was obviously reduced in the 3 dose DY groups (P < 0.05, P < 0.01). Meanwhile, the auricle swelling degree was superior in high and middle dose DY groups to that in the loratadine group (P < 0.05). The inhibition ratio of auricle swelling was sequenced from high to low as 67.3% in the high dose DY group, 56.0% in the middle dose DY group, 48.1% in the low dose DY group, 47.3% in the loratadine group.
CONCLUSIONSDY could inhibit auricle swelling and lower serum IgE level. It also could inhibit delayed allergic reaction in model mice with QBDS to some extent.

Oxidative stress is a redox imbalance in the body, which is one of the important factors leading to tissue damage and diseases. The nuclear factor E2-related factor 2 (Nrf2)-Kelch like ECH-associated protein 1 (Keap1) signaling pathway is not only an important defense system against oxidative damage, but also one of the key signaling pathways of the antioxidant capacity. Numerous studies have shown that targeting the Keap1-Nrf2 signaling pathway to activate Nrf2 has become an effective strategy for the treatment of oxidative stress and related diseases. Using small molecules to directly block the Keap1-Nrf2 protein-protein interaction (PPI) is one of the important directions for activating Nrf2 and exerting the cytoprotective effect, which can avoid the potential side effects of covalent modification of Nrf2. On the other hand, the Keap1 is an efficient E3 ubiquitin ligase that has been used in the design of proteolysis targeting chimeras (PROTACs). This review summarizes the research progresses of Keap1-Nrf2 protein interaction inhibitors and degraders based on the Keap1 E3 ubiquitination system in recent years.

Spleen kidney Yang deficiency (SKYD) diarrhea is a common syndrome in tranditional Chinese medicine (TCM). Until now, there is not an ideal SKYD diarrhea rat model for the research. In this study, we compared single factor way (method I, injecting hydrocortisone and gavaging Sennae Folium) with compound factors way(method II, gavaging adenine, improper diet, exhaustion, and gavaging Sennae Folium) on establishing SKYD diarrhea rat model. After modelling, diarrhea index, D-xylose excretory rate, NOS/cGMP signal transduction system, organ index and histopathology examination were used to evaluate the two ways. The results showed that, compared with health group, all the assessment criterias of method I and method II had significant differences (P < 0.01, 0.05). In addition, the index such as diarrhea index, NOS/cGMP signal transduction system, organ index (kidney, testis and thymus) and histopathology examination had significant differences (P < 0.01, 0.05) between method I and method II. In conclusion, the compound factors modelling method better conforms to the symptom of diarrhoea model caused by SKYD. This new modelling method provides a basis for studying on TCM astringents warming and tonifying the spleen and kidney, relieving diarrhea.

OBJECTIVETo study the ability of bone marrow mesenchymal stem cells (BMSCs) to repair the internal environment of the testis in male azoospermia rats.
METHODSWe established azoospermia models in 22 six-week-old male SD rats by intraperitoneal injection of busulfan at 20 mg per kg body weight. We transplanted allogeneic rat BMSCs (rBMSCs) into the testicular seminiferous tubules of the model rats and, 30 days after transplantation, observed the composition and structure of the seminiferous tubular cells by HE staining and detected the expressions of CD44, CD106, and c-kit in the rBMSCs by immunohistochemistry.
RESULTSThe number of epididymal sperm was significantly reduced in the model rats as compared with the normal controls (P < 0.01). CD44 and CD106, but not c-kit, were expressed in the isolated rBMSCs. At 30 days after transplantation of rBMSCs, lots of new cells were observed in the seminiferous tubules, some expressing CD106 and some expressing the germ cell surface marker c-kit.
CONCLUSIONBMSCs can transdifferentiate into germ cells and repair the damaged seminiferous tubules of sterile rats.

OBJECTIVETo observe the effect of Ginkgo Leaves Tablet (GLT) on memory quotient (MQ) of mild cognitive impairment (MCI) patients.
METHODSOne hundred and thirteen patients were randomly assigned to the control group (55 cases) and the treatment group (58 cases). Patients in the control group received dietetic therapy and physical exercises, while those in the treatment group additionally took GLT, 19.2 mg each time, three times daily. The treatment course was 12 months for all. The MQ of all the patients was assessed by WMS-RC before treatment,at 6-month of treatment, and 12-month of treatment.
RESULTSCompared with the control group, the improvement of MQ increased in the treatment group 0.5 and 1 year after treatment (P < 0.05). The clinical efficiency of MQ obviously increased in the treatment group (48.28% and 50.00%), showing statistical difference when compared with the control group (30.91% and 27.27%, P < 0.05, P < 0.01). There was statistical difference in added scores of recognition, regeneration, understanding, and recitation test at 6-month of treatment and 12-month of treatment between the treatment group and the control group (P < 0.05, P < 0.01).
CONCLUSIONGLT was effective in improving MQ of MCI patients, especially in improving recognition, regeneration, understanding, and recitation test.
