Chinese Journal of Primary Medicine and Pharmacy 2012;19(15):2246-2248
Objective To observe the changes of plasma lipoprotein concentrations after an oral glucose tolerance test and research their relation to insulin resistance in Type 2 diabetic patients.Methods The age,duration of diabetes,sex,waist circumference,hip circumference,waist-hip ratio,height,body weight,body mass index ( BMI ),systolic blood pressure,diastolic blood pressure,fasting plasma glucose,HbAl C,fasting insulin,and fasting and 60-,120-,180-minute post-load plasma glucose,plasma insulin,triglycerides ( TG),high-density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol(LDL-C) and total cholesterol(TC) after a 75-g oral glucose tolerance test were measured in 26 Type 2 diabetic patients.Comparison of plasma fasting lipoprotein concentrations and postload lipoprotein concentrations was made,and the relation between fasting and post-load lipoprotein concentrations and Homa-IR was researched.Stepwise multiple regression analysis was applied to investigate the areas under the lipoproteins' curves over 180 minutes.Results The declination of post-load lipoprotein concentrations after the 75-g glucose tolerance test was statistically significant( all P <0.01 ).Plasma TG concentration both in fasting and post-load state was positively related to Homa-IR( all P < 0.05 ),and plasma HDL-C concentration in fasting and post-load state was negatively related to Homa-IR( all P < 0.05 ).However,the correlation between both fasting and post-load state LDL-C and TC concentration and Homa-IR had no statistical significance.Moreover,stepwise multiple regression analysis revealed Homa-IR was the independent factor capable of modulating the area of HDL-C curve over 180 minutes after the 75-g glucose tolernce test ( P < 0.05 ).Conclusion There was a significant declination of plasma lipoproteins after a 75-g glucose tolerance test,and plasma fasting and post-load TG and HDL-C concentrations were related to insulin resistance.Insulin resistance should play a significant role in the post-load HDL-C concentration after 75-goral glucose tolerance test.

Chinese Journal of Rehabilitation Theory and Practice 2014;(6):585-587
Objective To observe the features of hypocalcemic myopathy secondary to hypoparathyroidism (HP). Methods The symp-toms and signs, laboratory findings and treatments of 13 patients with hypocalcemic myopathy secondary to HP were analyzed retrospective-ly. Results 13 cases of HP were classified into idiopathic HP (8 cases), secondary HP (3 cases) and pseudo-HP (2 cases). The symptoms of hypocalcemic myopathy secondary to HP included tetany, episodic carpopedal spasm, muscle cramps and myalgias in the forearms and calves. It presented blepharospasm, trunk spasm and laryngospasm. Some patients demonstrated positive Trousseau's and Chvostek's sign. Serum level of creatine kinase (CK) and lactate dehydrogenase (LDH) increased. The symptoms of myopathy released and the levels of CK and LDH decreased to normal level after enough calcium carbonate and calcitriol administration. Conclusion All types of HP (idiopathic, secondary and pseudo HP) can cause hypocalcemia and myopathy. Hypocalcemic myopathy secondary to HP would well recover by enough calcium carbonate and calcitriol treatment.

Objective To find out the relationship between the serum resistin levels and obesity, insulin sensitivity, blood-glucose as well as blood lipid in the elderly with diabetes. Methods Senile patients (51) suffering from type 2 diabetes and non-diabetic controls(42) were selected. Their serum resistin levels after an overnight fasting were measured by competitive ELISA. Other data including fasting blood-glucose, insulin, blood lipid, insulin sensitivity index, waistline, hipline and WHR were measured. Results (1)In non-diabetic controls, fasting resistin level was significantly higher in obese subjects than that in those persons with normal weight (P

Changes in respiratory function before and after CPB in 40 children with state of left-to-right shunt of VSD were studied. Among the cases, 20 of them were with pulmonary hypertension (PH group ) and 20 without PH (control group). Before CPB, resist ante of inspira tion (RI) and resistance of expiration (RE)in PH group (23.87?7.53,42.98?12.1) were significantly higher than those of control group(RI 17.95?7.53,RE 34.95?5.13);compliance of lung-thorax(CLT) in PH group(11.58?4.87) was significantly lower than that of control group(14.32?1.99). After CPB. both RI (30.94?11.89) and RE(46.43?9.9) in PH group were greatly higher than those in control group (28.00?9.29,46.43?9.9);CLT (10.98?4.6) was lower than that of control group (12.3?2.68). In PH group,the PaO_2 decreased and the magnitude of A-aDO2 increased much more than those in control group. The results suggest that respiratory function in the children with PH might not be improved immediately after CPB separation.

Objective To assess the value of dual-energy computed tomography myelography (CTM) on detecting leaks of cerebrospinal fluid (CSF) in patients with spontaneous intracranial hypotension (SIH). Methods Six patients with SIH underwent spinal CTM on a 2nd generation dual-source CT with tube voltage set at 100 and 140 kVp(with tin filter). The virtual non-contrast (VNC) and iodine map images were calculated from dual-energy images. The average weighted (AW) CTM images were mixed from two kVp images with mix factor of 0. 5. Two radiologists evaluated CSF leak using two sets of images respectively: VNC + iodine map images and AW-CTM images. The results from two reading methods were compared. The level of CSF leaks along the nerve roots, C1-2 retrospinal CSF collections, epidural CSF collections and spinal epidural venous plexus were marked. The consensus about leak sites and CSF collections was made by two radiologists in the third session Kappa statistics were used to measure the agreement between the two methods. Results Forty-one leaks were detected using VNC + iodine map images. Forty-three leaks were detected on AW images. The agreement between two methods was excellent (Kappa =0. 997 ,P <0. 01). There were no differences in the detection of C1-2 retrospinal CSF collections (n = 2), epidural CSF collections(n = 3) or spinal epidural venous plexus (n = 1). VNC and iodine map images demonstrated superior visual effects than AW images. Conclusion Dual-energy CTM can be used to diagnose spontaneous spinal cerebrospinal fluid leaks in SIH patient.
