Objective To investigate the effects of omega-3 polyunsaturated fatty acids (ω-3 PUFA) on inflammatory response,nerve damage,and outcomes in patients with severe traumatic brain injury (sTBI).Methods Altogether 120 sTBI patients were selected from January 2013 to September 2014 in Jinjiang Hospital of Traditional Chinese Medicine and divided with a random number table into experimental group (with ω-3 PUFA supplementation,n =60) and control group (without ω-3 PUFA supplementation,n =60).Sixty blood samples from healthy people visiting the physical examination clinic were collected as normal controls.The serum levels of tumor necrosis factor-α (TNF-α),interleukin (IL)-1,IL-6,S100B and neuron-specific enolase (NSE) were detected with enzyme-linked immunosorbent assay (ELISA).Glasgow Coma Scale (GCS) score,Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ score and outcomes of the two groups were compared.Results The serum levels ofTNF-α,IL-1,IL-6,S100B,and NSE protein significantly increased in patients with sTBI compared with the normal controls (all P ＜ 0.05).Compared with the control group,the serum levels of inflammatory related factors (TNF-α,IL-1,IL-6) in the experimental group were significantly decreased on the 3rd day [(213.81 ±29.33) μg/L vs.(267.76 ±31.35) μg/L,(121.81 ± 10.63) μg/L vs.(152.60 ± 11.45) μg/L,(81.89 ± 8.34) μg/L vs.(106.62 ± 10.35) μg/L,all P ＜ 0.05],S100B and NSE protein expressions were significantly decreased on the 7th day [(1.32 ± 0.09) μg/L vs.(1.67 ± 0.12) μg/L,(12.57 ± 1.53) μg/L vs.(17.57 ±2.30) μg/L,both P ＜0.05].Compresd with the control group,the experimental group showed significantly higher GCS scores (9.32 ± 1.64 vs.7.14 ± 1.30,P =0.02) and significantly lower APACHE Ⅱ scores (14.37 ± 2.27 vs.17.00 ± 1.85,P =0.04) on the 14th day.Compresd with the control group,the experimental group showed lower mortality during the follow-up [11.7％ (7/60) vs.15.0％ (9/60)],but with no significant differences (P =0.49).Conclusion Supplementation of ω-3 PUFA could exert neuroprotective effect by effectively regulating inflammatory response and reducing the damages to glia and neurons in patients with sTBI,which is a promising agent for clinical application.

Objective: To investigate the clinical research of Guo's Liulian therapy in treating acute pancreatitis intestinal mucosal barrier dysfunction and provide reference for the patients with acute pancreatitis. Methods: The 68 patients with acute pancreatitis who were admitted to our hospital from September 2016 to May 2018 were selected as study subjects. According to the random number table method, the patients were divided into the observation group and the control group, with 34 cases in each group. The patients in the control group were treated with conventional western medicine. The patients in the observation group were treated with Guo's Liulian therapy on the basis of the above treatment. The time of intestinal paralysis was compared between the two groups. The changes of intestinal mucosal barrier function and serum inflammatory factor related indexes before and after treatment were analyzed in the two groups. The difference of therapeutic effects between the two groups was observed. Results: In the observation group, the abdominal pain relief time, abdominal distention relief time, bowel sound recovery time, and first bowel anus defecation time were significantly lower than those in the control group (t=7.621, 5.332 6.625, 8.762, all Ps<0.01). After treatment, serum LPS, DAO, ET, D-lactic acid, TNF-α, IL-1, IL-6, IL-8, and IL-10 and urine L/M were significantly lower in the observation group, while the serum ITF and MFG-E8 were significantly higher in the observation group (t=9.856, 6.974, 9.784, 16.068, 9.550, 12.506, 22.343, 16.625, 6.774, 23.469, 20.118, 23.031, all Ps<0.01). Conclusions The Guo's Liulian therapy treatment of acute pancreatitis in patients with intestinal mucosal barrier dysfunction can reduce the palsy remission time, reduce inflammation, increase serum ITF, MFG-E8 levels, repair of intestinal permeability, and improve the intestinal barrier function.
