Objective To investigate the association of insulin dose with clinical factors of type 2 diabetes. Methods We reviewed the data of 214 type 2 diabetic patients who received insulin regimens.We compared the insulin dose and period at the targeted blood glucose levels among 6 groups according to different type of oral hypoglycemic agents. Results There existed statistically significant correlations of the glucose-targeted insulin dose with course,FPG,BMI,combination therapy with oral hypoglycemic agent(P<0.1,test level P=0.1).Merely metformin failure group took less insulin than the group admitted due to combination therapy failure (P=0.016, 0.53(0.35～0.62)U/kg and 0.63(0.51～0.75)U/kg respectively).The longest targeted period existed in the later. Relationship between the targeted bedtime insulin NPH dose and FPG level can be demonstrated by equation Y=0.255X+7.8. Conclusions The targeted insulin dose is influenced by synthetic factors. Patients admitted due to combination oral hypoglycemic drug failure have the maximal targeted insulin dose and the longest titration period. The final bedtime insulinNPH dose can be predicted by FPG level.

Objective To study the value of MRI in the diagnosis of spinal metastasis.Methods MR imaging manifestations of spinal metastasis in 85 cases were retrospectively analyzed.46 cases underwent CT and/or X-ray in the 85 cases.Results Totally 388 metastatic vertebra in the 85 cases were detected by MRI.388 vertebras showed hypointensity on T1WI.354 vertebra showed mixed signal intensity and 34 vertebra showed hypointensity on T2WI.All of the vertebra showed hyperintensity on T2WI/STIR.54 vertebra showed pathologic fracture,53 vertebra were protrusion in postetrior,54 vertebra with appendages damage and paravertebral soft tissue mass presented and vertebral canal involved in 30 cases.18 cases were detected with lesion in 46 cases having X-ray and/or CT data,the positive rate was 39.11%(18/46).Conclusion MRI can detect spinal metastatic lesion early,the extent and degree of the tumors can be judged by MRI exactly.

Cardiac toxicity is found in frequently used chemotherapeutic agents.There are many factors related to the cardiac toxicity caused by chemotherapeutic agents.The common cardiovascular complications include heart failure,ischemia,hypertension,hypotension,edema,QT prolongation,pleural effusion,pericardial effusion,bradyarrhythmia and thromboembolism.It is necessary to monitor the left ventricular function before and after chemotherapy and take effective measures to protect myocardium.

Objective To investigate the effects ofdocosahexenoic acid (DHA) on large conductance Ca2+-activated K+ (BK) channels in normal retinal artery smooth muscle cells (RASMCs).Methods Cultured human RASMCs (6 th-8 th generations) were used to patch clamp experiment.The open probabihties (NP0) in BK channels with different concentrations (0.0,1.0,3.0,5.0,7.5,10.0 μmol/L) of DHA were recorded by patch clamp technique in single channel configuration.RASMCs were intervened by different concentrations (0.0,1.0,5.0 μmol/L) of DHA as control group,low and high doses of DHA groups,respectively.The protein expressions of β subunit of BK channels in RASMCs from three groups were measured by Western blot.Results The NP0 of BK channels were 0.044 4±0.001 2,0.081 2±0.004 2,0.209 0±0.006 1,0.310 5±0.005 3,0.465 0±0.007 8 and 0.497 7±0.014 5 with perfusate of 0.0,1.0,3.0,5.0,7.5,10.0 μtmol/L DHA.DHA activated BK channels in a dose-dependent manner (F=2.621,P＜0.05).There was no significant difference in the protein expression of control group,low and high doses of DHA groups (F=1 1.657,P＞0.05).Conclusion DHA can directly activate BK channels,no increasing in subunit expression of BK channels.

Objective To explore the effect of TCM differentiated treatment and nursing on patients with multiple myeloma and blood stasis.Methods Two hundred and thirteen patients with multiple myeloma and blood stasis were managed with TCM differentiated treatment and nursing.The blood-stasis score was compared before the treatment and two curative courses after the treatment.Result The blood-stasis score significantly decreased after treatment(P<0.01).Conclusions TCM differentiated treatment with diet instruction and emotional comfort can improve the symptom of multiple myeloma with blood stasis,promote the life quality of the patients.

Objective To evaluate the clinical effects of platelet-rich plasma in treatment of DeepⅡburn wounds. Methods Sixty eight cases of inpatients with Deep Ⅱburns were selected, whose age were from 1 to 65 years and their burn areas were between 5%~62%of total body surface area (TBSA). Deep gradeⅡburn of each sample was divided into two parts. Part A was the treatment group and part B was the control group.The burn wounds in the treatment group were treated with platelet-rich plasma and the counterpart in the control group were treated with SD-Ag. Healing time ,recovering rate and the frequency of dressing changes,frequency of changing the most innerlayer gauze and the rate of wound infection were also analyzed. Finally the laboratory abnormalities and adverse effect were monitored regularly. Results The healing time of the treatment group (16.5±3.1 ) d was shorter than that of the control group (19.5±3.8 ) d. The recovering rate of the treatment group was higher than that of the control group on the 14th and 17th day after treatment. There were statistically sig?nificant differences between these two groups (P<0.05). After two weeks’treatment, the internal and external dressing per?meability into wet gauze layers were 20.6 ± 1.7, which were significantly decreased than that in the control group 23.3 ± 5.9. The frequency of dressing changes was(7.2±1.1)times in treatment group versus(9.2±1.4)times in control group and the frequency of changing the inner most layer gauze was( 2.3±0.6)times in the treatment group versus(5.3±1.3)times in con?trol group. There were 5 inflammation reaction cases in the treatment group, but 13 cases in the control group. However, there was no statistic significance between the two group in the outcomes of bacterial culture, the laboratory abnormalities and the adverse effect. Conclusion Platelet-rich plasma can remarkably shorten the healing time,improve healing rate,re?duce frequency of dressing change and promote wound healing for deepⅡburn wound. PRP is a potential safety reagent in treating deepⅡburn wound.

Objective To investigate effects of Kanglaite injection on proliferation, cycle and apoptosis of human breast cancer MCF-7 cells;To discuss its relevant mechanism. Methods Logarithmic growth phase cells were divided into control group and Kanglaite-treatment group (10, 20, 40μL/mL). Cells were cultured in RPMI-1640 for 24 h before drug treatment. The inhibition rate of Kanglaite injection on proliferation of human breast cancer MCF-7 cells was detected by MTT assay. Apoptosis and cell cycle of MCF-7 cells were detected by flow cytometry. Changes in cell nucleus were determined by Hochest staining assay. Protein expressions of Bcl-2 and Bax were detected by ELISA and Western blot. Results Kanglaite injection for 12 h, 24 h or 48 h resulted in a significant inhibition of MCF-7 cells proliferation (P<0.05, P<0.01);Compared with the control group, Kanglaite injection-treated cells showed increased percentage in G2/M and G0/G1 phases (P<0.001, P<0.01), but showed decreased percentage in S phase (P<0.01), and apoptosis rate increased (P<0.05, P<0.001). Kanglaite injection significantly decreased protein expression of Bcl-2, and enhanced protein expression of Bax of MCF-7 cells (P<0.01, P<0.001). Conclusion Kanglaite injection can inhibit the proliferation of human breast cancer MCF-7 cells, decrease cell cycle and induce apoptosis, the mechanism is related with decreasing protein expression of Bcl-2 and enhance the protein expression of Bax.

Background:Helicobacter pylori( Hp)is listed as Group 1 human carcinogen. Transcription factor FOX family plays important role in the development of tumor,and FOXA1 is a key target transcription factor of some microRNAs( miRNAs). Aims:To investigate the relationship of Hp infection with expression of FOXA1 in gastric mucosal tissues. Methods:Eighty patients undergone gastroscopy from Jan. 2014 Sept. 2014 were enrolled. Hp infection was detected by 14 C-urease breath test( 14 C-UBT),modified Giemsa staining and bacterial culture. Expression of FOXA1 in gastric mucosal tissues was determined by immunohistochemical SP method. Results:FOXA1 expression in Hp positive tissues was significantly higher than that in Hp negative tissues(73. 8% vs. 47. 4%;χ2 =4. 81,P<0. 05). Conclusions:High expression of FOXA1 in gastric mucosal tissues suggests that miRNAs pathway may be one of the molecular mechanisms of Hp infection leading to gastric intraepithelial neoplasia even gastric cancer.
