ABSTRACT
Objective:To observe the clinical efficacy of long-time needle retaining at Baihui(GV20)on post-stroke cognitive impairment(PSCI)and its effects on the cognitive ability and living ability of the patients.Methods:A total of 62 PSCI patients were divided into a control group and an observation group by the random number table method,with 31 cases in each group.The control group was treated with routine treatment for stroke in the recovery period plus cognitive training.The observation group received additional acupuncture at Baihui(GV20)with long-time needle retaining based on the same intervention in the control group.The Montreal cognitive assessment(MoCA)was used to evaluate the cognitive ability of patients.The activities of daily living(ADL)scale was used to evaluate the living ability of patients.And the mini-mental state examination(MMSE)scale was used to evaluate the mental state,concentration,language,and abstraction cognition of patients.After 4 weeks,the curative efficacy was observed,and the scores of cognitive level,living ability,mental state and concentration,language,and abstraction understanding ability were compared between the two groups.Results:During the trial,1 patient in each group dropped out due to personal reasons and was unable to continue the treatment.After 4 weeks of treatment,the total effective rate was 83.3%in the observation group and 66.7%in the control group,and the difference between the two groups was statistically significant(P<0.05);the scores of MoCA,ADL,and MMSE,and scores of concentration,language ability,and abstraction understanding ability were all increased,and were statistically different from those before treatment in each group(P<0.05);the scores in the observation group were all higher than those in the control group,and the differences between the groups were statistically significant(P<0.05).Conclusion:On the basis of routine treatment and cognitive training,the clinical efficacy of additional acupuncture at Baihui(GV20)with long-time needle retaining in the treatment of PSCI is better than that of routine treatment plus cognitive training;the treatment can better improve the cognitive function and mental state of patients,and improve their living ability.
ABSTRACT
Objective To investigate the effects of different high-fat diet feeding time durations on blood glucose (BG), insulin resistance index(HOMA-IR), and urinary albumin excretion rate(UAER)in rats with high fat diet-induced type 2 diabetic nephropathy(DN). Methods Unilateral renal artery ligation, high-fat diet(throughout the ex-periment period),and low dose streptozotocin(STZ)intraperitoneal injection were used to establish a type 2 DN rat mod-el. After the operation,rats in the DN1 and DN2 groups received an intraperitoneal injection of STZ 30 mg/kg after 4 and 8 weeks of high-fat diet feeding,respectively. UAERs of the DN1 and DN2 groups were compared at 4 weeks after the STZ injection and the end of study(EOS). BG,body weight,HOMA-IR,kidney index,and pathological changes of the kidney were observed. Results UAER was increased in both groups at 4 weeks after the STZ injection,but significantly higher in the group DN2 than in the DN1 group(P<0.01). At the end of study(the 12th week),the renal tissues showed patho-logical changes,including glomerular capillary loop hypertrophy,increased mesangial matrix,and decreased capsule space in both groups. Compared with the DN1 group,the body weight was significantly higher(P<0.01),kidney index was sig-nificantly lower(P<0.01),while BG,serum insulin level,HOMA-IR,and UAER were no significantly changed in the DM2 group(P>0.05,respectively). Conclusions The results show that extending the feeding time of high-fat diet can aggravate the kidney damages in diabetic rats,but it can also delay the start of any planned intervention. Therefore,the ex-perimental protocol should be carefully designed based on the study objective.
