Objective To investigate the clinical effects of comprehensive rehabilitation treatment for patients with a diabetic foot. Methods Fifty-two patients with one diabetic foot were randomly divided into a rehabilitation group ( n =26 ) and a control group ( n =26).The patients in the control group received conventional treatment including health education,basic medical therapy and focal treatment of the foot.In addition to the conventional treatment,the rehabilitation group was treated with aerobic exercise,Beecher's exercise regimen,infrared therapy and ultrashortwave therapy 6 days a week for 4 weeks.The therapeutic effect and quality of life were evaluated before and after treatment. Results The effectiveness rate of the rehabilitation group was significantly higher than that of the control group ( 88.46％ vs 73.08％ ) after treatment.The quality of life scores in both groups were significantly better than those before treatment,including on the social relationship dimension,the physiological function dimension,the mental/psychology dimension and the therapy influence section.Average quality of life scores in the rehabilitation group had improved significantly more than in the control group. Conclusion Comprehensive rehabilitation is beneficial to prevent the progress of diabetic foot and to improve the quality of life of patients with a diabetic foot.

OBJECTIVE: To discuss the types of control groups in randomized controlled trials (RCTs) of Chinese herbal medicine (CHM), and to provide suggestions for improving the design of control group in future clinical studies in this therapeutic area. METHODS: A search of the Cochrane Library was conducted in July 2005 to identify RCTs of CHM, and 66 RCTs with CHM for type 2 diabetes mellitus were obtained as the basis for further analysis. RESULTS: Of 66 RCTs with CHM for type 2 diabetes mellitus, 61 (92.4%) trials had both a treatment group and a control group. Twenty-seven (40.9%) RCTs compared CHM plus conventional drug vs conventional drug, 24 (36.4%) compared CHM vs conventional drug, 5 (7.6%) compared CHM vs placebo, 3 (4.5%) compared CHM plus conventional drug vs conventional drug plus placebo, 3 (4.5%) compared CHM plus conventional drug vs other CHM, 1 (1.5%) compared CHM vs no treatment, 1 (1.5%) compared CHM plus placebo vs conventional drug plus placebo, 1 (1.5%) compared CHM vs CHM plus conventional drug vs conventional drug vs placebo, and 1 (1.5%) compared CHM vs conventional drug vs CHM plus conventional drug. CONCLUSION: A variety of control groups were used in RCTs of CHM for type 2 diabetes mellitus, including placebo, active, and no treatment control groups. Justification for selecting particular types of control groups were not provided in the trials reviewed in this study. Different control groups may be appropriate according to the study objectives, and several factors should be considered prior to selecting control groups in future RCTs of CHM. RECOMMENDATIONS: (1) Investigators of CHM who design clinical trials should understand the rationale for selecting different types of control groups; (2) Control groups for RCTs should be selected according to study objectives; (3) Active control groups should select interventions for comparisons that have the strongest evidence of efficacy and prescribe them as recommended; (4) Placebo control groups should select a placebo that mimics the physical characteristics of test intervention as closely as possible and is completely inert; (5) No treatment control groups should only be used when withholding treatment is ethical and objectives outcomes will not be subject to bias due to absent blinding; (6) Crossover control groups may be appropriate in chronic and stable conditions.

Objective To investigate the effects of D-limonene on the proliferation and ras P21 expression in human bladder carcinoma EJ cell.Methods The cell proliferation was measured by XTT assay.The expression of ras mRNA was detected by real-time PCR,and the expression of its protein product was analyzed by Western Blot.Results The proliferation of EJ cell was inhibited by exposure to 2 mmol/L and 4 mmol/L D-limonene for 48h.The optical density (A) was 0.801±0.016 and 0.148±0.008,respectively.There were significant differences between the experimental groups and the control group (1.2181±0.031,P<0.05).The expressions of ras P21 and its protein product of EJ cell were decreased obviously when exposure to 1 mmol/L of D-limonene for 48h.The expres-sions were significantly different compared with the control group(P<0.05).Conclusions D-limo-nene could inhibit human bladder carcinoma EJ cell proliferation,which is in a dose-dependant man-ner.In a lower dose (<1 mmol/L),D-limonene can decrease the expression of ras mRNA and its protein product.

Objective To investigate the effect of high frequency (10 Hz),low frequency (1 Hz) and theta burst stimulation (TBS) mode of repetitive transcranial magnetic stimulation (rTMS) on the recovery of motor function in hemiplegic patients following acute ischemic stroke.Methods Seventy-two patients with hemiplegia after acute ischemic stroke were randomly grouped with the random number table.They were treated with low frequency (n=18),high frequency (n=18),and TBS (n=18) rTMS or sham stimulation (control group,n=18),once a day,for 2 weeks.Fugl-Meyer Assessment (FMA) and National Institutes of Health Stroke Scale (NIHSS) were used to evaluate neurological function in all patients before rTMS treatment (on the day before the first treatment) and after treatment (on the day after the last treatment).Results After treatment,the FMA and NIHSS scores in the 4 groups were significantly improved compared with before treatment (all P<0.05).After rTMS treatment,the FMA and NIHSS scores were improved significantly in the high frequency group,low frequency group and TBS group compare with the control group (all P<0.05).There were no significant differences among all the treatment groups.Conclusion sHigh frequency,low frequency and TBS rTMS can improve the recovery of motor function in hemiplegic patients following acute ischemic stroke.There were no significant differences among all the treatment modes.

Objective:To investigate the neuroprotective effect of long-term prophylactic use of buphthalein on mice with permanent distal middle cerebral artery occlusion and its relationship with the nuclear factor erysid 2 related factor 2 (Nrf2) pathway.Methods:Nrf2 + /+ wild-type and Nrf2 -/- knockout mice were randomly divided into control group (equal volume vegetable oil), low-dose butylphthalide group (20 mg/kg) and high-dose butylphthalide group (60 mg/kg), with 6 mice in each group. The drug was administered once a day by gavage for 1 month, and then a permanent middle cerebral artery occlusion model was induced by electrocoagulation. After the model was made, the drug was continued and the mice were sacrificed on the 10 th day. The modified Longa grading scale and the rotating rod test were used to evaluate neurological deficits on the 3 rd and 10 th day after the model was made. After the mice were sacrificed, the cerebral infarct volume was measured by triphenyltetrazolium chloride staining. The brain water content was measured by dry and wet weight method. The expression of Nrf2 pathway related factors, including Nrf2, heme oxygenase 1 (HO-1) and NAD(P)H quinone oxidoreductase 1 (NQO1) were measured by quantitative real-time PCR and Western blotting. Results:On the 10 th day after modeling, compared with the Nrf2 -/- control group, the neurological deficit was significantly milder, the volume of cerebral infarction and brain water content were significantly smaller, and the mRNA and protein levels of Nrf2, HO-1 and NQO1 were significantly higher in the Nrf2 + /+ control group, and the differences were statistically significant ( P<0.05). For Nrf2 + /+ mice, compared with the control group, the cerebral infarct volume was significantly reduced ( P<0.05), the brain water content was significantly reduced ( P<0.05), and the neurological function recovery was significantly better ( P<0.05), and the levels of Nrf2, HO-1, and NQO1 mRNA and protein were significantly higher in the high-dose butylphthalide group (all P<0.05). For Nrf2 -/- mice, there were no significant differences in neurological function, cerebral infarction group volume, brain water content, Nrf2, HO-1, NQO1 mRNA and protein levels among the groups. Conclusion:Long-term butylphthalide pretreatment can significantly improve the neurological function, reduce cerebral infarction volume, reduce brain water content, and increase Nrf2, HO-1, NQO1 mRNA and protein expression levels in mice with permanent distal middle cerebral artery occlusion, suggesting butylphthalide may play a neuroprotective effect by up-regulating the expression of Nrf2 gene and its downstream antioxidant stress factors HO-1 and NQO1.

Objective To study the best diagnostic imaging procedure after acute stroke.Methods 53 patients with acute stroke were recruited within 72 hours after symptom onset.CT was performed in all patients firstly, then T1 weighted-imaging( T1 WI), T2 weighted-imaging( T2WI ), gradient recalled echo T2 * weighted-imaging( GRE-T2 * WI) and diffusion-weighted imaging(DWI) were examined at 1.5T.Furthermore 15 patients with ischemic stroke received perfusion-weighted imaging(PWI) examination.Results 15 patients with acute cerebral hemorrhage and one patient of hemorrhagic brain tumor appeared clear on GRE-T2 * WI.3 patients with transient ischemic attack(TIA) were normal on T1WI ,T2WI ,GRE-T2* WI and DWI.18 cases with cerebral infarction appeared normal on GRE-T2 * WI within 6 hours after symptom onset, and 7 cases of them underwent PWI examination, the signal intensity of 3 cases were PWI ≥ DWI and of 4 cases were PWI = DWI.14 patients appeared hyperintense on GRE-T2 * WI within 6 ～72 hours after symptom onset.8 patients of them underwent PWI examination,the signal intensity of 6 cases were PWI≥DWI and of 2 cases were PWI = DWI.Of 14 patients,7 patients appeared as 1 ～ 18 dot or patchy hypointense whose diameter was about 2 ～ 5mm on GRE-T2 * WI.Another case of headache with hemiplegia and the side of the limb didnt show abnormalities on the CT, but showed a low signal in ambient cistern on T2 * WI and was proved to be subarachnoid hemorrhage.Conclusion After acute stroke,multi-sequence MRI enables the "one-stop shopping" imaging of cerebral hemorrhage,cerebral infarction and TIA in a shorter time,makes the state of micro-bleeding clear,determines ischemic penumbra,and even guides for thrombolytic treatment.

Objective:To explore the effect of failure mode and effects analysis (FMEA) on the postoperative complications in patients with cerebral angiography.Methods:Using the convenient sampling method, a total of 167 patients with cerebral angiography who were admitted to Shanxi Provincial People's Hospital from March 2016 to January 2019 were selected as research objects and they were divided into two groups according to the implementation of FMEA. The observation group (after the implementation of FMEA) used FMEA method to calculate of priority risk number (RPN) in failure mode to determine the nursing plan for clinical nursing, while the control group (before the implementation of FMEA) was given routine nursing. The postoperative RPN, complications and nursing satisfaction were compared between the two groups.Results:RPN of each failure mode in the observation group was significantly lower than that in the control group. The total incidence of complications in the observation group were lower than those in the control group, and the differences were statistically significant ( P<0.01) . The scores of nursing satisfaction in health education, professional degree of nursing behaviors, nursing requirement satisfaction degree, nursing attitude and nursing skills of the observation group were significantly higher than those of the control group, and the differences were statistically significant ( P<0.01) . Conclusions:FMEA method analyzes the causes of complications of cerebral angiography and formulates targeted nursing plans according to the causes, so as to make the operation process more standardized and scientific, effectively reduce postoperative complications of patients and improve nursing satisfaction.

OBJECTIVE: To discuss the quality of reporting in randomized controlled trials (RCTs) of Chinese herbal medicine (CHM), and to provide suggestions for improving the reporting of future clinical studies in this therapeutic area. METHODS: A search of the Cochrane Library was conducted to identify RCTs of CHM. A revised CONSORT checklist designed for CHM clinical studies was implemented. The revised CONSORT checklist contained 63 items, including the following new items added specifically for CHM: (1) "syndrome of disease" based on Chinese medicine theories; (2) rationale of CHM formula; (3) formula composition; (4) preparation form of CHM; (5) quality control of CHM. RESULTS: The overall reporting quality of the RCTs as assessed with the revised CONSORT checklist varied between 19% and 44%, with a median score of 32% (standard deviation 8%). CONCLUSION: The overall quality of reporting of RCTs of CHM evaluated with a revised CONSORT checklist was poor, reflecting the need for improvements in reporting future clinical trials in this area. RECOMMENDATIONS: To improve the quality of reporting of RCTs of CHM, we recommend adopting a revised CONSORT checklist that includes items specific to CHM. We also recommend that editors of CHM journals require authors to use a structured approach to presenting their trials as a condition of publication.
