Tumor 2008;28(8):672-675
Objective: To investigate the distribution of somatostatin receptor 2 subtype (SSTR2) in small cell lung cancer (SCLC) in vitro and the value of 99mTc-octreotide scintigraphy for SCLC diagnosis in vivo. Methods: The distribution of SSTR2 was detected by electron microscopic autoradiography (EMR) using 125I octreotide. 99mTc-octreotide (0.15 mL, 16.8 MBq) was injected into nude mice via tail veins and 99mTc-octreotide scintigraphy was observed. Results: The tagged rates of cellular sliver grains were 95.0% (19/20) and 85.0% (16/20) at 30 min and 120 min, respectively. The difference was significant (P < 0.05). Sliver grains were distributed in the membranes at 30 min and located in the nucleolus and cytoplasm at 120 min. The numbers of sliver grains in the control group (addition of over Tyr 3-octreotide) were remarkably less than those of group 30 min and 120 min. The scintigraphy of the tumors in 5 nude mice was positively displayed at 4 h postinjection of 99mTc octreotide. Conclusions: SSTR2 is over-expressed in SCLC. Radiolabeled octreotide scintigraphy may become a novel detection method for early diagnosis of SCLC.

Objective:To compare the effects of different doses of atorvastatin on blood lipid and endothelial function in patients with hypertension and carotid plaque.Methods:Ninety-two patients with hypertension and carotid plaque who received treatment from June 2019 to June 2020 were included in this study. They were assigned to receive treatment with either atorvastatin 20 mg (control group, n = 46) or atorvastatin 40 mg (study group, n = 46) for 3 months. Blood lipid level and endothelial function were compared between the two groups. Results:There were no significant differences in sex, age, course of disease, body mass index (BMI) and carotid plaque grading between the two groups (all P > 0.05). Before treatment, there were no significant differences in serum levels of total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) between two groups (all P > 0.05). After treatment, serum levels of TC, TG and LDL-C in each group were significantly decreased compared with before treatment [study group: TC: (5.8 ± 2.3) mmol/L vs. (3.5 ± 1.3) mmol/L, t = 5.904; TG: (2.5 ± 0.8) mmol/L vs. (1.2 ± 0.5) mmol/L, t = 9.346; LDL-C: (5.0 ± 0.4) mmol/L vs. (3.3 ± 0.4) mmol/L, t = 20.382; control group: TC: (5.9 ± 1.8) mmol/L vs. (4.5 ± 1.5) mmol/L, t = 4.052; TG: (2.6 ± 0.3) mmol/L vs. (1.8 ± 0.7) mmol/L, t = 7.125; LDL-C: (4.9 ± 0.5) mmol/L vs. (4.2 ± 0.5) mmol/L, t = 6.714, all P < 0.01). After treatment, serum level of HDL-C in each group was significantly increased compared with before treatment [study group: (0.8 ± 0.5) mmol/L vs. (1.5 ± 0.3) mmol/L, t = 8.142; control group: (0.8 ± 0.4) mmol/L vs. (1.3 ± 0.2) mmol/ L, t = 7.583, both P < 0.01]. After treatment, serum levels of TC, TG and LDL-C in the study group were significantly lower than those in the control group ( tTC = 3.417, tTG = 4.731, tLDL-C = 9.533, all P < 0.01). After treatment, serum level of HDL-C in the study group was significantly higher than that in the control group ( tHDL-C = 3.762, P < 0.01). Before treatment, there were no significant differences in endothelium-dependent (flow mediated dilation, FMD) and endothelium-independent diastolic function (nitroglycerin- mediated dilatation, NMD) between the two groups (both P > 0.05). After treatment, FMD in each group was significantly enhanced compared with before treatment [study group: (7.5 ± 1.8) % vs. (10.9 ± 2.5) %, t = 7.486; control group: (7.7 ± 1.5) % vs. (8.9 ± 2.2) %, t = 3.057; both P < 0.05]. After treatment, FMD in the study group was significantly higher than that in the control group ( t = 4.073, P < 0.01). There was no significant difference in NMD between before and after treatment in the control group. After treatment, NMD in the study group was significantly increased compared with before treatment [(12.5 ± 2.3) % vs. (13.6 ± 2.5) %, t = 2.196, P = 0.031]. Conclusion:Atorvastatin 40 mg once a day can effectively regulate blood lipid level and improve endothelial function in patients with hypertension and carotid plaque, which exhibits superior effects to atorvastatin 20 mg once a day.

Objective To conduct a hiomechanical comparison of the four common internal fixation methods for the anterior eruciate ligament(ACL)avulsion fractures of displaced tibial eminence.Methods Sixteen fresh cadaver knee joints were used and randomized into four equal groups of four fixation methods:antegrade wiring group, retrograde wiring group,suturation group,and intramedullary screw group.The knee joint specimens were fixed at flexion of 30?and subject to continuous stretch stresses of 30 N,60 N and 90 N respectively on a material testing machine(MTS 858 Bionix test system,USA)which conducted a simulated Lachman test.The specimens were scanned at different angles by a three dimensional laser scanner.Data were recorded and processed by image software to es- tablish three-dimensional structure models of femur,tibia and knee joint.The test results were analyzed statistically on a computer.Results There were no obvious differences between each fixation group in the length change of ACL when the stresses were 30 N and 60 N(P>0.05).Under 90 N stress,however,the mean length change between the femoral and tibial attachments of ACL was the smallest(4.8?1.7)mm(2.5 to 6.2 mm)in the suturation group(P<0.05). There were no distinct differences between the intramedullary screw group and the retrograde wiring group in the changes of A CL shift(P=0.214).The average front shift in the retrograde wiring group was(6.2?1.2)mm(4.8 to 8.2 mm) and significantly smaller than that in the antegrade wiring group(P<0.05).The antegrade wiring group made the largest average front shift under different stresses and its average front shift was(7.2?1.3)mm(5.6 to 8.7 mm). Conclusions The knee joint stability provided by the suturation fixation is distinctly better than that by the other three fixation methods.The antegrade wire fixation provides the poorest knee joint stability.There is hardly any difference between intramedullary screw fixation and retrograde wiring fixation.

Objective: To explore the early diaghostic value of thyroid hormone level in patients with left ventricular diastolic dysfunction. Methods: Our work included 4 groups:①Normal control group, n=40,②Impaired left ventricular diastolic function
group, n=40,③Failure of left ventricular diastolic function group, n=41 and④Impaired left ventricular systolic function group, n=40. The cardiac function was assessed by color Doppler lfow imaging and tissue Doppler imaging for the early diastolic mitral lfow velocity (E), the peak early diastolic mitral annular velocity (Em) and the ratio of E/Em. The blood levels of NT-proBNP and FT3, FT4, TSH, rT3 were examined in clinical laboratory.
Results: Blood levels of FT3 and rT3 were different in pair wise comparison among 4 groups, P<0.05, and FT4 and NT-proBNP were different in pair wise comparison among 4 groups, except for Normal control group and Impaired left ventricular diastolic function group, P<0.05. The TSH level was similar among 4 groups, P>0.05. The ratio of E/Em was negatively related to FT3 (r=-0.724, P<0.05) and FT4 (r=-0.49, P<0.05), while positively related to rT3 (r=0.87, P<0.05) and NT-proBNP (r=0.83, P<0.05).
Conclusion: The changes of thyroid hormone level may exist in patients with impaired diastolic function and it may vary with the severity of the cardiac dysfunction. Blood levels of NT-proBNP with thyroid hormone might be used as a reference index for early diagnosis of diastolic dysfunction.
