OBJECTIVETo observe the efficacy of Xingnaojing Injection (XI) in treatment of sepsis-associated encephalopathy (SAE).

METHODSTotally 65 SAE patients were retrospectively analyzed at EICU from September 2010 to September 2013. They were assigned to the control group (32 cases) and the treatment group (33 cases) according to whether they received XI. Patients in the control group received anti-infection and symptomatic support, while those in the treatment group were intravenously injected with XI at 20 mL per day for additional 7-10 days. The fever clearance time, Glasgow coma scale (GCS), C-reactive protein (CRP), neuron-specific enolase (NSE), and improvement of electroen-cephalogram (EEG) were observed in the two groups.

RESULTSCompared with the control group, the fever clearance time was shortened, CRP levels decreased, GCS score and efficacy of EEG was alleviated in the treatment group after treatment with statistical difference (P < 0.05). No adverse reaction occurred during medication.

CONCLUSIONX1 was safe and effective in treatment of SAE.

Objective To evaluate the effect of curcumin on the inflammatory responses in the hippocampus during global cerebral ischemia-reperfusion (I/R) injury in hypertensive rats.Methods Forty-eight SPF male Wistar-Kyoto rats,aged 8 weeks,weighing 180-200 g,were randomly divided into 2 groups (n =24 each) using a random number table:sham operation group (W-Sham group) and I/R group (W-I/R group).Seventy-two SPF male spontaneously hypertensive rats,aged 8 weeks,weighing 180-200 g,were randomly divided into 3 groups (n =24 each) using a random number table:sham operation group (S-Sham group),I/R group (S-I/R group),and curcumin group (S-Cur group).Global cerebral ischemia was induced by 4-vessel occlusion method (10 min of transient global ischemia followed by reperfusion).Curcumin 100 mg/kg was injected intraperitoneally at 30 min of reperfusion in S-Cur group,and corn oil 5 ml/kg was injected intraperitoneally at 30 min of reperfusion in the other groups.The ability of learning and memory was tested by step-down test at 7 days of reperfusion.Rats were sacrificed at 3 h and 1,3 and 7 days of reperfusion (T1-4) and the hippocampi were removed.The morphological changes of pyramidal cells in hippocampal CA1 area were observed by HE staining.The mean density of pyramidal cells in hippocampal CA1 area was quantified by Nissl staining.The contents of interleukin-lβ (IL-1β),tumor necrosis factor-alpha (TNF-α) and IL-10 in the hippocampus were determined by ELISA.Results Compared with W-Sham group,the ability of learning and memory was significantly decreased,the mean density of pyramidal cells in hippocampal CA1 area was decreased,the contents of IL-1β at T1-3,TNF-α at T1,and IL-10 at T2 were increased,and the contents of IL-10 were decreased at T1,3,4 in W-I/R group,and no significant changes were found in the parameters mentioned above in S-Sham group.Compared with W-I/R group,the ability of learning and memory was significantly decreased,the contents of IL-1β at T1,3 and IL-10 at T2 were decreased,the content of TNF-α was increased at T1,no significant change was found in the mean density of pyramidal cells in hippocampal CA1 area,and the damage to pyramidal cells in hippocampal CA1 area was severe in S-I/R group.Compared with S-I/R group,the ability of learning and memory was significantly increased,the mean density of pyramidal cells in hippocampal CA1 area was increased,the contents of IL-1β at T2,3 and TNF-α at T1-4 were increased,and the content of IL-10 was increased at T2,and the damage to pyramidal cells in hippocampal CA1 area was reduced in S-Cur group.Conclusion Inhibition of inflammatory responses in the hippocampus may be involved in the mechanism by which curcumin reduces global cerebral I/R injury in hypertensive rats.

Objective:To systematically evaluate the therapeutic efficacy of tuina therapy for primary insomnia.Methods:Nine Chinese and English databases were searched from the inception to May 2017 to identify randomized controlled trials (RCTs) studying tuina therapy for insomnia.The enrolled articles were all RCTs with tuina as the monotherapy or major therapy in the experiment group,with clear diagnostic criteria for primary insomnia well recognized worldwide or in China,and Pittsburgh sleep quality index (PSQ I) as one of the outcome measures.Two researchers evaluated the risk of bias and quality of the enrolled studies by following Cochrane Handbook version 5.1.0.The meta-analysis was performed by RevMan version 5.3.Results:Eleven studies were included with a total of 1 076 participants.The Western medication adopted in the control groups were benzodiazepine receptor agonists.The studies were all assessed as high risk of bias for blinding since blinding method was unable to be performed due to the specificity of tuina therapy;no study reported the support of fund or potential interest conflict,so they were all rated unclear for selective reporting.The meta-analysis showed that compared with other traditional Chinese medicine therapies,tuina worked more effectively in reducing the PSQI score (MD=-4.11＜0,95％ confidence interval (CI)-6.01 to-2.22,P＜0.0001);compared with oral administration of Western medication,tuina showed more significant efficacy in reducing the PSQI score (MD=-3.42＜0,95％CI-5.19 to-1.66,P＜0.0001).Subgroup analysis showed that head tuina alone showed no significant difference compared with oral administration of Western medication regarding the change of PSQI score (MD=-4.19＜0,95％CI-8.87 to 0.50,P＞0.05);a combination of head and back tuina could more effectively reduce the PSQI score compared with oral administration of Western medication (MD=-2.08＜0,95％CI-3.09 to-1.06,P＜0.0001).Conclusion:Tuina can produce more significant efficacy in treating primary insomnia compared with other traditional Chinese medicine therapies and oral administration of Western medication,especially the combination of head and back tuina.

OBJECTIVETo investigate the effect of curcumin on the injury in hippocampal neurons and the expression of regulated upon activation nonnal T-cell expressed and secreted (RANTES) in hippocamp during cerebral ischemia/reperfusion (I/R) in rats with spontaneous hypertension (SH).

METHODSMale Wistar-Kyoto (WKY) rats and spontaneous hypertension rats (SHR) were randomly divided into five groups (n = 6): sham group (W-Sham and S-Sham group), ischemia/reperfusion group (W-/R and S/R group), curcumin group (S-Cur group) . Each group was splitted into 5 subgroups of 3 h,12 h, 1 d, 3 d and 7 d according to the time interval before reperfusion. Global brain ischemia/reperfusion model was established by 4-VO method. Hematoxylin-eosin staining (HE staining) was used to observe the vertebral cell morphology in hippocampal CA1 region. Nissl staining was applied to detect the average density of cone cells in hippocampal CA1 region. The expression of RANTES in hippocamp was determined by ELISA. The behavior of the rats was evaluated at 7 days after reperfusion. Results: Compared with the sham group rats, the ability of learning and memory was significantly decreased in ischemia/reperfusion group rats, the number of injured neurons were greatly elevated , the protein expression levels of RANTES was significantly increased (P < 0.05). Compared with W-I/R group rats, the ability of learning and memory in S-I/R group rats was greatly reduced, the number of injured neurons increased extremely, the protein expression level of RANTES was significantly enhanced( P <0.05). The number of injured neurons declined significantly in S-Cur group rats, the ability to learn and remember of these rats was improved and the RANTES protein content decreased significantly (P < 0.05).

CONCLUSIONSHR are more susceptible to ischemia/reperfusion induced hippocampal neuronal injury which may be improved by curcu min. Its underlying mechanism is possibly associated with the inhibition of RANTES protein expression level.
