Results After treatment, all indexes of the trial group were markedly improved compared with before treatment (P 0.05). The rate of AE in the trial group was less than that in the control group. Conclusion Qingre Jiangzhuo prescription has curative effect on type 2 diabetes mellitus patients with better safety.

Objective To observe and analyze the change state of serum inflammatory mediators of patients with secondary septic shock after chemotherapy for acute leukemia .Methods 56 patients with secondary septic shock after chemotherapy for acute leukemiawere were selected as the group A,56 patients without secondary septic shock after chemotherapy for acute leukemia were selected as the group B ,56 healthy persons of the same age were selected as the group C,then the serum inflammatory mediators levels of three groups were detected and compared,and the serum indexes of group A with different severity degree of shock were compared, then the detection results of group A and group B with different types ( lymphocytic leukemia and nonlymphocytic leukemia)were compared.Results The serum inflammatory mediators levels, including TNF-α, IL-4, IL-6, IL-10 and other inflammatory factors, including PGE2 , sICAM-1, sVCAM-1 and sCD44, there were group A >group B >group C, severe shock >moderate shock>mild shock ( all P<0.05 ) .The above serum inflammatory mediators and other inflammatory factors levels of different types in group A were higher than those in group B, and the above mediators in lymphocytic leukemia of group A and group B were higher than those in nonlymphocytic leukemia (all P<0.05).Conclusion The serum inflammatory mediators of patients with secondary septic shock after chemotherapy for acute leukemia show higher expression state,and the influence of shock degree and leukemia types for the expression are great.

In the present paper, the contribution of the largest principal component and the number of principal component needed for accumulative contribution 95% are selected as indices of electroencephalogram (EEG) in mental fatigue state in order to investigate the relationship between these parameters and mental fatigue. The experimental results showed that the contribution of the largest principal component of EEG signals increased in the prefrontal, frontal and central areas, while the number of principal component needed for accumulative contribution decreased by 95% with the increasing mental fatigue level. The parameters of singular system of EEG signals can be regarded as useful features for the estimation of mental fatigue and have larger application value in the study of mental fatigue.

Objective To establish a continuous monitoring assay of serum argininosuccinate lyase (ASL) activity with automatic biochemistry analyzer, and perform methodology validation and preliminary clinical application.Methods According to the chemical reaction catalyzed by ASL and the working characteristics of automatic biochemistry analyzer, an enzyme coupled reaction system with high specificity was set up, and the methodology validation was performed.Three hundred and nine patients with various liver diseases, 269 non-liver disease patients and 40 healthy controls were enrolled in this study.Serum ASL, ALT, and AST level were determined in all subjects.Results A new kinetics assay of ASL activity was set up with automatic biochemistry analyzer.The methodological validation demonstratod that inter-assay and intra-assay coefficient of variation were 4.0% and 5.9% respectively and the mean recovery was 100.5%.The linear range was 0-167.7 U/L.The lowest detection limit was approximately 0 U/L.The interference test showed that there is no significant interferences while the concentration of bilirubin is less than 342 μmoL/L or commonly used anticoagulants is employed at their routine concentrations.However,interference was significant when Hb level is more than 0.06 g/L.Preliminary study of clinical application showed that there was no significant difference of serum ASL level between non-liver disease group and healthy group ( q = 0.027, P = 0.979 ), but there was significant differences for both serum ALT and AST levels (ALT:q =6.461,P =0.000;AST:q =6.481,P =0.000).Conclusions A continuous monitoring assay for the determination of serum ASL activity is successfully established. Serum ASL may be a good biomarker for liver injury.

The paper analyzed legally the following predicaments of legitimization of rural doctors in China:no legitimacy protection for their practice,vague criteria for practicing medicine,conflicts between legal regulations for medical practice and rural realities,and lack of a liability insurance system.The authors,based on an exploration of the legislative framework for rural doctors,made four corresponding legislative proposals as follows:to clearly define the legal scope and identity of rural doctors,to establish a qualification and employment system for rural doctors,to develop practicing norms applicable for rural doctors,and to set standards for their income.

Objective To investigate the effect of early systemic nursing intervention applied by ward nurse on constipation among patients with depression. Methods A total of 144 participants were divided into the intervention group (72 cases) andthe control group (72 cases) by random number table. Except for a period of 4 weeks routine nursing and 4 weeks follow-up observation which were applied for control subjects, systemic nursing interventions werealso conducted inintervention patients. The incidence of constipation and constipation symptom scoreswere measured at the ends of the 4th and 8th week of treatment. Results The incidences of constipation and constipation symptom scores of the 4th and 8th weekend in the intervention group were 17.6% (12/68), 6.59 ± 4.08, 23.5% (16/68) and 6.81 ± 3.99 respectively. While in the control group they were 34.9%(22/63), 8.84 ± 4.45, 44.4%(28/63) and 10.52 ± 3.86 respectively. These differences between two groups at the 4th and 8th weekend were all significant (χ2=5.077, t=3.023, P < 0.05 and χ2=6.413, t=5.411, P < 0.05, respectively). Compared with the 4th weekend, in the 8th weekend, constipation rate and scores of constipation symptom were increased in thecontrol group (P < 0.05), but not in theintervention group (t=-1.965, P > 0.05). Conclusions In patients with depression, early systemic nursing intervention can effectively ameliorate the constipation caused by amitriptyline.

Objective To study the connection between MRI characteristics of spinal cavernous hemangioma(SCH)and its clinical and pathological features.Methods 20 cases of SCH confirmed by pathology were retrospectively analysed.The characteristics of MRI signal intensity were analysed in comparison with the clinical manifestations and pathology.Results Among the 20 cases,5 lesions located in the cervical segment of spinal cord,12 lesions in the thoracic segment,2 in the lumbar segment and 1 in the thoracic-lumbar segement.SCH could be devided into four patterns:intramedullary lesion,epidural lesion,intradural-extramedulary lesion and vertebral lesion.The typical MRI characteristics of SCH were mixed signal intersity on T_1 or T_2 weighted images,low signal intensity ring could be seen around the lesions and more pronounced on T_2 images.Spinal cord compression syndrome was the main clinical manifestation.Cavernous hemangiomas were red or purple mulberg-like lesions which were composed of dilated,thin-walled vessel with a simple endothelial lining and a variably thin fibrous adventitia under the microscope.Conclusion MRI is the most reliable method in diagnosing SCH,MRI characteristics of signal intensity of SCH are correspond with their clinical and pathological features.
