Objective Discussion of diagnosing insulinoma.Methods Retrospective analysis based on 45 cases of insulinoma patients that are collected by General Surgery Department in the First Affiliated Hospital of Zhengzhou University from June 2008 to October 2014.Results Forty-five cases of patients with insulinoma including 41 cases (91.11％) of functional insulinoma and 4 cases (8.89％) of non-functional insulinoma.Apply selective arteriography,preoperative ultrasound,intraoperative ultrasound and CT to diagnosis.Forty-five cases of patients with insulinoma,in which 18 cases with laparoscopic simple tumor resection,6 cases with laparoscopic splenectomy and tail of the pancreas resection;45 cases of insulinoma with laprotomy,in which 8 cases with pancreaticoduodenectomy,12 cases which the tumors were located in the neck,neck-line of the pancreas with local excision of the pancreas and pancreatic tail-jejunal Roux-en-Y anastomosis,one cases of laparotomy found no placeholder.Conclusions Surgery removal is currently the most successful way to eliminate insulinoma.And localization diagnosis can determine the outcome of the surgery.Co-operation of surgery removal and localization diagnosis can be the optimal approach to diagnose certain insulinoma.

Objective To analyze the value of PET/CT for diagnosis of recurrence and metastasis of dif-ferentiated thyroid carcinoma ( DTC) .Methods 65 patients with DTC in Thyroid Surgery Department of the First Affiliated Hospital of Zhengzhou University from Dec .2005 to Jan.2015 were collected.Based on the values of serum thyroglobulin(Tg),the patients were divided into 2 groups.29 cases with positive Tg were the observation group and 36 cases with negative Tg were the control group .All patients underwent PET/CT examination one year after surgery.Patients with positive findings from image studies underwent surgical excision and postoperative pathological diagnosis .Clinical data of the 2 groups were then summarized and discussed .Results There was no significant difference on the general conditions between the 2 groups(P>0.05).Tg values were statistically dif-ferent 6 months and 1 year after surgery between the 2 groups(P<0.05).Tg values of both groups decreased 1 year after surgery, but without statistical difference (P>0.05).9 cases in the observation group and 1 case in the control group had positive findings on image study .All the cases with cervical lymph nodes presented as high uptake of 18 F-FDG.All patients who had positive findings on PET/CT underwent surgical removal of the abnormal lymph nodes which confirmed by pathology as lymph node metastasis .Conclusion PET/CT is very important for diagno-sis of recurrence and metastasis on Tg(Tg>2μg/L)positive,131I Dx-WBS imaging and US negative patients.

Objective To study the change of mid-regional pro-adrenomedullin(MR-proADM) level in patients with chronic heart failure and its significance.Methods Randomly selected 330 patients with chronic heart failure,including 120 cases of grade Ⅱ and Ⅲ,90 cases of grade Ⅳ,90 cases were selected.,Within 24 h after the entry of the group and 7 d after symptom relieved,serum N-terminal pro-B-type natriuretic peptide(NT-proBNP),MR-proADM,cardiac ultrasound(left ventricular diameter(LVEDD) and left ventricular function(LVEF)) were measured.Ninety physical examination in the same period as healthy control during the same period.The change of MR-proADM level in patients with chronic heart failure and its significance were analyze.Results Compared with the healthy control group,the level of MR-proADM in patients with chronic heart failure(grade Ⅱ:(641.55±106.34) pmol/l;grade Ⅲ:(684.46±101.33) pmol/l;grade Ⅳ:(737.81±479.37) pmol/l) was significantly higher than that in the control group(610.22±60.84) pmol/l),the difference was statistically significant(F=5.33,P=0.001).At the same time,the level of MR-proADM was increased with the aggravation of heart failure,after drug treatment will decline((608.09±100.81),(617.64±94.32),(642.22±163.53) pmol/L).And MR-proADM levels were significantly positively correlated with NT-proBNP levels and NYHA classification in patients with heart failure(r=0.194,P=0.003;r=0.206,P=0.000).Conclusion MR-proADM has important guiding significance in the diagnosis,classification of patients with chronic heart failure.

Objective To define the variety and action mechanism of endogenous health resources as well as their economic features, utilization results and influence and to put forward suggestions for giving priority to their development in policy making. Methods Materials from on the spot investigations and materials already available were used to conduct a positive economic study by means of combining document summaries with descriptive studies and analyses. Results Static, exogenous and endogenous health resources were defined, the contribution rate of progress in science and technology in 23 hospitals was determined to be 35.5%, senior human resources were found to be scarce, and the competitiveness of hospitals at the central hospital level was discovered to be weak. Conclusion Effective utilization and optimum distribution of endogenous health resources constitute the key to the realization of the structural readjustment of the health industry and the attainment of sustainable economic growth and development.

OBJECTIVETo study the biomechanical change of the craniovertebral junction in conditions of atlas assimilation.

METHODSMimics software was used to process CT data of the craniovertebral junction in a health adult to obtain the three-dimensional reconstruction and the cloudy points of C1, C2 and part of the occipital bone. Then the cloudy points were imported into the Abaqus 6. 8 software to establish the occipito-atlantoaxial finite element model in normal structure. According to the established model in normal structure, the model in conditions of atlas assimilation was set by changing the model parameters. Both models of normal structure and atlas assimilation were loaded with 1. 5 N . m static moment to simulate four motions of flexion, extension, lateral bending and axial rotation respectively. The movement characteristics,joint stress force and ligament deformation was analyzed.

RESULTSUnder 1. 5 N . m moment, in model of atlas assimilation the C1-C2 range of movement decreased from 13. 55° to 11.88° in flexion,increased from 13. 22° to 15. 24° in extension and from 4. 05° to 4. 23° in lateral bending and remained unchanged in axial rotation when compared with the normal model. In flexion movement, the contact force of the atlanto-dental joint increased from 1. 59 MPa to 3. 28 MPa and the deflection of apical ligament, tectorial membrane and alar ligament increased 129. 1%, 157. 6% and 75. 1% respectively when compared with the normal model.

CONCLUSIONSThe normal C1-C2 motion mode is destructed in conditions of atlas assimilation, leading to the changes of the range of movement,joint stress force and the ligament deformation at C1 C2 junction. The atlantoaxial instability will likely occur in flexion motion.

Objective To study the effect of Pingchuan Formula(PCF)on Rho/Rock signaling pathway in the mice of asthmatic model, explore the mechanism of PCF on asthma. Methods Forty BALB/C mice were randomly divided into four groups:a control group, a model group,a dexamethasone group and a PCF group. After treated with medicine for 4 weeks, albumen expression of RhoA and RockI in lung tissues were detected by using Western blot, mRNA expressions of RhoA and RockI were detected by using Real-time PCR. Results The albumen and the mRNA expression of RhoA and RockI in the model group were(1.05± 0.20),(1.06±0.08),(6.60±1.09), (6.53±1.84), the control group were(0.76±0.08), (0.84±0.14), (3.82± 1.77), (3.65±1.46),there was a significant difference between two groups(P<0.01). The albumen and the mRNA expression of RhoA and RockI in the dexamethasone group were(0.78±0.11), (0.87±0.32), (4.19± 2.33), (4.09±1.08), there was a significant difference compared with the model group(P<0.01). The PCF group were(0.86±0.12), (0.93±0.14), (4.38±2.01), (4.50±1.13), there was a difference compared with the model group(P<0.05). These was no difference between the dexamethasone group and the PCF group(P>0.05). Conclusion The expressions of Rho/Rock signaling pathway were controlled significantly by PCF, and the curative effect was similar to dexamethasone.
