Objective: To observe the clinical efficacy of Xingnao-Kaiqiao acupuncture("醒脑开窍"针法) on patients with cerebral infarction.Methods: Sixty-three patients with the disease were randomly divided into treatment group(n=32) treated with Xingnao-Kaiqiao acupuncture and control group(n=31) with(traditional) acupuncture.In addition,routine medicine therapies were given to the two groups(including(dehydration),(decrease) of intracranial pressure,enhancement of nerve nutrition and supportive treatment).(Xingnao-)(Kaiqiao acupuncture) was used and adjusted the number of points with different syndromes in the treatment group,main points were as follows: Neiguan(内关PC6),(Rengzhong)(人中GV26),Sanyinjiao((三阴交)SP6) and vice points were Jiquan(极泉HT1),Chize ((尺泽LU5)),Weizhong(委中BL40),Fengchi(风池GB20),Yintang (印堂EX-HN3),Shangxing((上星DU23)-through-Baihui)(百会GV20).Traditional acupuncture was used in the control group.Points at the upper limbs were Jianjing(肩井GB 21),Quchi(曲池LI 11),Waiguan(外关(S)51),Hegu(合谷LI 4) and at the lower limbs were Zusanli(足三里ST36),Yanglingquan(阳陵泉GB34),Huantiao(环跳GB30),Fenglong(丰隆ST40),Kunlun(昆仑BL60) etc..Acupuncture was given twice a day for 15 days in both groups.Before and after therapy,the hemorrheology,blood lipid,blood,urine,stool and biochemical routine examinations,white blood cell (WBC) count in(peripheral) blood and neurological deficit score(NDS) were(determined).Curative effects of two groups after treatment were observed.Results: After treatment,the total effective power was 93.75% in the treatment group,while it was 67.74% in the control group,the difference being significant (?~2=4.85,P

Background The incidence of dry eye is gradually increased,and researches showed that inflammation participated in the pathogenesis and development of dry eye.The current therapy for dry eye can only relieve symptom but not achieve final cure.Stem cell therapy has been used in the treatment of limbal stem cell deficiency.However,whether it is feasible for the stem cell treating dry eye is still unclear.Objective This study attempted to investigate a new approach to treat dry eye syndrom by using human umbilical cord mesenchymal stem cells (HUCMSCs).Methods The use and care of experimental animals complied with the Tsinghua University School of Medicine Laboratory Animal Care Details.HUCMSCs were cultured and cell suspension was prepared with the cell density of 5×105/ml.Twenty 24-week-old male NOD/Ltj mice were randomized into 4 groups.0.1 ml PBSHUCMSCs suspension was injected via tail vein or lacrimal respectively in the caudal vein injection group and lacrimal injection group,and 10 μ1 PBS-HUCMSCs suspension was topically administed in the eye drops group.The NOD/Ltj mice without any treatment served as the model group.Five male ICR mice were used as the normal control group.Tear secretion was quantitatively detected with phenol red cotton thread in 1,2,3 weeks after injection,and corneal epithelial defect was scored by fluorescein staining.The serum levels of interleukin (IL)-6,IL-17a,tumor necrosis factor-α (TNF-αt) and interferon-γ (IFN-γ) were assayed by ELISA.The relative expression levels of p65,Stat3,Stat5 and extracellular signal-regulated kinases (Erk)-1 in lacrimal gland were detected by Western blot.Results The tear secretion amount was significantly different among the model group,caudal vein injection group,lacrimal injection group and eye drops group in various time points (1 week:F =3.700,P =0.040;2 weeks:F =5.150,P =0.008;3 weeks:F=10.130,P＜0.001).The tear secretion amount was increased in the caudal vein injection group and lacrimal injection group compared with the model group in different time points (all at P＜0.05),and no significant difference was seen in tear secretion amount between eye drops group and model group among various time points (all at P＞0.05).The fluorescein staining score was 3.00±0.63,9.40±1.62,5.20±1.17,4.20±1.17 and 7.20±0.98 in the ICR mouse control group,model group,caudal vein injection group,lacrimal injection group and eye drops group 1 week after injection respectively,and the scores were significantly lower in the caudal vein injection group,lacrimal injection group and eye drops group than those in the model group (P =0.001,0.000,0.033).The serum levels of IL-6,IL-17a and TNF-α in the caudal vein injection group were evidently lower than those in the model group (t =4.70,3.46,11.0,all at P＜0.01),but no significant difference was displayed in the serum IFN-γ level among the five groups (F=1.740,P=0.170).The expressions of STAT5 were significantly decreased in the mice treated with tail vein injection and lacrimal injection compared with mice without treatment (both at P＜0.05).Conclusions Administration of HUCMSCs via intravenous and lacrimal injection can alleviate the inflammatory response during progression of dry eye syndrome by down-regulating the serum level and expression of inflammation-related factors in NOD/Ltj mice.The topical administration of HUCMSCs eye drops can attenuate the symptom of dry eyes by lubricating the cornea and suppling nutrition.
