Objective To investigate the effect of combination therapy of Gabapentin and Cobamamide in treatment of painful diabetic neuropathy (PDN).Methods A total of 96 patients with type 2 diabetes (T2DM) and PDN were enrolled in this study and randomly divided into control group (Con,n=32),Cobamamide group,(n=32),and Gabapentin+Cobamamide group,(n=32).FPG and HbA1c were actively controlled in each group.Con group was treated with vitamin B1.Clinical and biochemical data of all the subjects were collected.The degree of pain was assessed by visual analogue scale (VAS).The changes of median nerve,peroneal nerve motor nerve conduction velocity (MNCV),and sensory nerve conduction velocity (SNCV) were evaluated by EMG assessment.The assessment of sleep quality was done by Pittsburgh sleep quality index scale (PSQI).Results There was no significant differences of baseline MNCV,SNCV and the degree of pain among the three groups (P>0.05).After treatment,all the above index were improved in both Cobamamide group and Gabapentin+Cobamamide group.MNCV and SNCV were higher in Gabapentin+Cobamamide group than in Cobamamide group (P<0.05).There were no significantly improvement of MNCV and SNCV in Con group (P>0.05).Conclusion The combination therapy of Gabapentin and adenosine cobalt amine could reduce pain,improve nerve conduction velocity,and improve the quality of sleep.

Objective To compare the efficacy and safety of prourokinase,reteplase and urokinase on the patients with acute ST -segment elvation myocardial infarction.Methods According to random number table,the eligible patients with acute ST -segment elvation myocardial infarction were randomly divided into prourokinase group (50mg,n =34),reteplase group (36mg,n =42)and urokinase group (1 500 000IU,n =32).The patency of infarct related coronary artery was estimated by coronary angiography at 90min after administration of thrombolytic agents.The adverse reaction was also observed including bleeding and the major adverse cardiac events(MACEs).Results The patency of culprit vessel in the prourokinase group was 76.50% (≥TIMI 2 flow),which in the reteplase group was 83.30% (≥TIMI 2 flow),and which in the urokinase group was 53.10% (≥TIMI 2 flow),respctively.Both of prourokinase group and reteplase group were higher in the patency than theurokinase group(χ2 =8.27,P =0.004). The MACEs and bleeding adverse reaction(prourokinase group 17.65%,reteplase group 28.57%,urokinase group 42.19%)showed that security of prourokinase group was securer than reteplase group and urokinase group(χ2 =6.36,P =0.012).Conclusion Both of prourokinase and reteplase are effective for the patients with acute myocardial infarction with ST -segment elvation,and prourokinase is safer.

Purpose At present,morphological observation and CT value measurement were mainly used to evaluate ground-glass nodule (GGN),and there was no effective image feature-quantization evaluation method.Therefore,in this study,a follow-up quantization analysis was conducted on GGN within 2 years using texture feature analysis method to confirm reasonable GGN follow-up time.Materials and Methods Baseline and highresolution CT images of 100 GGN follow-up patients were retrospectively analyzed.They were assigned into three groups,3 months follow-up (group A),6 to 12 months follow-up (group B) and 2 years follow-up (group C).For each group,using firstly founded GGN image as baseline,GGN texture features (including energy,contrast,autocorrelation,inverse difference moment and entropy) were analyzed.Results There were 1 case of narrowed nodules in group A,1 case of increased nodules and 1 case of narrowed nodules in group B,and 4 cases of increased nodules in group C,2 of which showed density differences.There was no significant change in shape,density and size of the remaining nodules.There were no significant differences in texture features (energy,contrast,autocorrelation,deficit,entropy) among group A,group B and group C (P＞0.05).Conclusion Texture feature analysis can quantitatively evaluate the change of GGN attribute characteristics,and as a GGN follow-up quantitative tool,it can guide patients to choose reasonable follow-up mode.

The variable heavy chain region (VH) genes of 3 untreated patients with B-cell chronic lymphocytic leukemia (B-CLL) were cloned and analyzed. The VH family used was VH3-11, VH3-72 and VH3-33. More than 2% difference from the corresponding germline gene was detected in all the 3 obtained potential functional genes (average 16.7). Mutation pattern analysis indicated evidence of antigen selective pressure observed in 1 of 3 cases. Our findings suggested that the tumor cells originate from post-GC cells.

Object To investigate the stability of baicalin in different conditions Methods The stability of baicalin in water with different pH values, methanol, ethanol, chloroform and in the mouse lung homogenate, mouse liver homogenate, mouse plasma and bovine serum was investigated by the classical isothermal method Results The experiments showed the baicalin was stable in acidic water and these organic solutions, but unstable in basic water and these biological media Conclusion The stability of baicalin in different media was different, which should be considered in practice

Objective: In order to provide an effective reference to the study on its preparation, the stability in vitro of andrographolide was investigated. Methods: Andrographolide was dissolved in phosphate buffer solutions of different pH values; classical isothermal method was employed; the content of andrographolide was determined by RP HPLC; then the stability of the drug in different biological media and organic solvents at 37?C was investigated. Results: The stability of andrographolide was different at different pH values and was best in the condition of pH=3～5. In biological media, it was most stable in bovine serum and the next was in mice homogenate. Conclusion: In different conditions, the stability of andrographolide was different. It provided a reference to the study on andrographolide and its preparation.

Objective To compare the effects of nonsurgical spinal decompression system (SDS) cervical traction and common cervical traction using surface electromyography (sEMG).Methods Twenty-two volunteers' sEMG signals were recorded before,during and after two modes of cervical traction:the conventional traction in sitting and SDS traction in supine.The interval between the two modes of traction was no shorter than 24 hours.The mean and peak amplitudes of their sEMG signals were observed before,during and after traction.The sEMG signals of the posterior cervical muscle while sitting or lying were compared at different stages of the traction.Results There was no statistically significant difference in sEMG signals between the subjects' right and left posterior cervical muscles.The sEMG signals decreased significantly during both traction trials.With common cervical traction the mean and peak amplitudes of the left posterior cervical muscle pre-and post-traction were higher than during traction,and the same as that of the right posterior cervical muscle.In the SDS trials the sEMG signals during traction and post-traction were significantly lower than those pre-traction.After traction the sEMG signals while sitting (common cervical traction) were significantly higher than those post-traction while lying (SDS cervical traction),and the sEMG signals post-traction while either lying or sitting were stronger than during traction while lying.The post-traction signals in sitting were stronger than those in lying.Conclusions Both nonsurgical SDS and common cervical traction can relax the posterior cervical muscles.The effect of nonsurgical SDS was better than that of common cervical traction.
