Objective To assess efficacy, infection rate and recurrence rate of tacrolimus prescribed in infants with steroid-resistant nephrotic syndrome (SRNS). Method From August 2011 to August 2014, 22 cases of SRNS infants (treatment group) received oral tacrolinms treatment, 0.1 to 0.15 mg/ kg per day and once every 12 hours were enrolled in this retrospective longitudinal study and were compared with 23 cases infant SRNS (control group) treated with high-dose methylprednisolone pulse therapy. Followed up for 1 year we analysed the data of proteinuria, lymphocyte count, proteinuria relapse and complication (infection, hyperglycemia) of the two groups’ patients at every point time. Results The pathology of the patients maintains of MCD, MsPGN, FSGS and IgM nephropathy so on. Follow-up to 6 months, the total remission rate 95.45% of treatment group was significantly higher than that in control group (60.87%). Follow-up to 6 months , 24 h urinary protein of the treatment group were respectively 67.88 mg/(kg·d) which were remarkably lower than base line [657.5 mg/(kg·d)], meanwhile which were obviously lower than the 6th month point of control group [305.55 mg/(kg·d)]. Lymphocyte counts had been done during the initial and the destination in the treatment group. Follow-up to 12 months, the CD4+ 795.16/uL, CD8+ 496.85/uL, CD19+ 358.23/uL had decreased observably than when at origin what was 2697.45/uL, 2265.63/uL, 1579.34/uL. Followed-up 1 year, the person-time of infection of treatment group existed superior to the control groups; The recurrence rate was 71.43% in treatment group, which compared with control groups (60.87%) without no significant difference. The treatment group with BG and CCr maintained stably. Conclusion Tacrolimus show its own advantages of reliable effect and less side-effect on the infant with steroid-resistant nephrotic symdrome associated with genes , but it could not lessen the relapse of the disease, and it′s long-term prognosis is still not very clear.

OBJECTIVETo observe the clinical efficacy on cognitive impairment after traumatic brain injury (TBD treated with acupuncture and cognitive training.

METHODSSixty patients were randomized into an observation group and a control group, 30 cases in each one, and 5 cases of them were dropped out due to the earlier discharge. Finally, there were 28 cases in the observation group and 27 cases in the control group. In the control group, the cognitive training and conventional treatment were applied. In the observation group, on the basis of the treatment as the control group, acupuncture was applied to Baihui (GV 20), Fengchi (GB 20), Geshu (BL 17) and Fenglong (ST 40), once a day, for 4 weeks totally. The mini-mental state examination (MMSE) and Montreal cognitive assessment (MoCA) were adopted to evaluate the cognitive function in the patients of post-TBI cognitive impairment.

RESULTS(1) After treatment, the total score in MMSE and the score of each item were increased significantly as compared with those before treatment in the two groups (all P<0. 05). Except for the score of immediate recall, the score in MMSE and the score of each of the other items were increased significantly in the observation group as compared with those in the control group after treatment (all P<0. 05). (2)After treatment, the total score in MoCA and the score of each item were increased significantly as compared with those before treatment in the two groups (all P<. 05). Except for the score of nomenclature item, the total score in MoCA and the score of each of the other items were increased significantly in the observation group as compared with those in the control group after treatment (all P<0. 05).

CONCLUSIONBoth the simple cognitive training and the combined therapy of acupuncture and cognitive training improve MMSE and MoCA scores and relieve the cognitive impairment induced by TBI. But the combined therapy achieves the much better efficacy.

Objective To observe the protective effect of Apelin-13 on the cerebral ischemia-reperfusion injury (CIRI), and to explore the possible mechanism in rat model. Methods Fifty male SD rats were randomly divided into five groups:sham group, CIRI model group and Apelin-13 (0.1, 1.0 and 10.0 μg/kg) treatment groups. The model of CIRI was established by filament. After 2 h ischemia, the focal middle cerebral artery was followed by 72 h reperfusion. Apelin-13 was administrated by intracerebroventricular injection 30 minutes before reperfusion. The score of neural function was estimated in different time points. The 2,3,5-triphenyl tetrazolium chloride (TTC) dye was used to calculate the volume and percentage of cerebral infarction. The endoplasmic reticulum stress (ERS) protein markers including glucose-regulated protein 78 (GRP78) and CCAAT/enhancer binding protein homologous protein (CHOP) in cerebral cortex were measured by Western blot assay. Results Compared with the sham group, the score of neural function was significantly increased, the infarct rate was reached(47.63 ± 5.81)%and the protein expressions of GRP78 and CHOP were significantly up-regulated in CIRI model group (P＜0.05). There were no significant differences in these data between the CIRI model group and 0.1 μg/kg Apelin-13 treatment group (P＞0.05). Compared with the CIRI group, the neural function defect was significantly improved, the muscle strength was significantly enhanced and the infarct rate was significantly decreased, and the protein expressions of GRP78 and CHOP were significantly down-regulated in the 1.0 and 10.0 μg/kg Apelin-13 treatment groups (P＜0.05). Conclusion Apelin-13 protects the cerebral ischemia-reperfusion injury in rat model, which may be related with the inhibition of endoplasmic reticulum stress.

Objective To observe the clinical efficacy of acupuncture and moxibustion combined with cognitive training in treating cognitive impairment after traumatic brain injury (TBI). MethodsSixty patients were recruited into the study and randomly divided into the control group and the treatment group according to the MINIMIZE software. Patients in the control group were treated with cognitive training and regular treatment. Besides the traditional treatment, patients in the treatment group were additionally treated with acupuncture and moxibution. The treatment lasted four weeks. Mini-Mental State Examination (MMSE) and Loewenstein Occupational Therapy Cognitive Assessment (LOTCA) were applied to evaluate the patients’ cognitive function before and after the treatment.Results In the end, there were 27 patients in the control group and 28 patients in the treatment group, because 5 patients withdrew from the study. After treatment, scores of MMSE, LOTCA and their sub-items in the control group and the treatment group increased significantly (P<0.05), and the scores in the treatment group were higher than the control group (P<0.05).Conclusion Combination of acupuncture, moxibution, and cognitive training could help patients after TBI to increase the scores of MMSE and LOTCA, and improve the cognitive impairment caused by TBI. Its therapeutic effect is superior than the pure cognitive training.
