Maternal-fetal ABO blood type incompatibility is an autoimmune disease.This disease can lead to miscarriage,stillbirth,children edema,early-onset neonatal jaundice,hemolytic anemia,kemicterus and neonatal death,etc.The author overviewed the etiology and pathogenesis of Matemal-fetal ABO blood type incompatibility,as well as the TCM therapeutic methods and effects in treating this disease at pre-pregnancy period and pregnancy.

Objective To compare the clinical efficacy and safety of domestic orlistat and imported orlistat in Chinese overweight and obese patients. Methods In a randomized, double-blinded and positive-controlled study, 228 adults (BMI 24-< 40 kg/m~2) evaluated at seven research centers were randomized to receive domestic orlistat or imported orlistat 120 mg 3 times a day with an energy-controlled diet for 24 weeks. Results After 24 weeks, domestic orlistat treated patients got significant weight-loss (5.0±3.7) kg, which was comparable with that of imported orlistat treated patients (4.5±3.5) kg (P=0.3922).Compared with the findings before treatment, there was significant decrease of systolic blood pressure (4.4±11.5)mm Hg (1 mm Hg=0.133 kPa) and serum levels of TC (0.54±0.79) mmol/L and LDL-C (0.32±0.64) mmol/L in the domestic orlistat treated group(compared with levels of baseline, P< 0. 0001). There was no significant difference between the two groups in the changes of blood pressure and lipid levels. Both groups had similar adverse event profiles, most of which were mild and transient gastrointestinal events. There were no serious adverse events in beth groups. Conclusions Domestic orlistat combined with a light low-energy diet promoted significant weight loss, which was comparable with that of imported orlistat after 24 weeks of treatment. There was also improvement in blood pressure and serum levels of TC and LDL-C. Domestic orlistat was as effective and safe as imported orlistat in the treatment of obesity.

Objective To evaluate the value of MSCT, MRI and SPECT in detecting acute myocardial ischemia in Chinese mini-swine model. Methods A total of six male mini-pigs were recruited with a mean body weight of (21.6 ± 1.2) kg. All pigs were scanned on MSCT before the ligation of distal segment of Left anterior descending artery. Then, MSCT was rescanned every 2 h from ligation till 8 h latter.MRI, SPECT and the last MSCT scan were performed within 24 h one by one. Finally pathological examination was carried out right after the pig killed. Results One pig died during operation, the other 5 finished all the examinations. The pathological staining showed the same areas of myocardial infarction in the left ventricular anterior wall with the all the imaging findings, including low perfusion region of MSCT arterial phase at 2-24 h, low perfusion region of SPECT at 24 h and low perfusion region of MRI first pass phase at 24 h. Three of 5 pigs showed enhanced edge of low perfusion region on MSCT delayed scan at 4-8 h. The mean CT values in the region with reduced first-pass perfusion were 75.9,36.4, 35. 2,37. 8,37.4,33.3 HU on MDCT image at baseline, 2-8 h after operation and within 24 h after operation, respectively,and there were statistically significant difference of CT values ( F = 12. 341, P ＜0. 01 ) between preoperative and all postoperative MSCT scan. There were no statistically significant difference (F = 2. 278, P = 0. 792)among all postoperative MSCT scan. At baseline, 2-8 h after operation and within 24 h, the average volumes of stroke volume(SV)were 21.7,11.9,10.3,11.4,12. 3,12.6 ml, respectively, while the average volume of end-systolic volume( ESV)were 15.2,23.4,25.0,24. 4,25.3,22. 8 ml,respectively. The average volume of end-diastolic volume ( EDV ) at these time point were 37. 0,35.4,35.0,35.7,37. 6,37.5 ml,respectively and the average percentage of ejection fraction (EF) were 58.9% ,33.8% ,29. 0%, 31.9%,32.6% ,33.5% ,respectively. SV(F =22. 349, P＜0.01) ,ESV (F=8. 810, P＜0.01) ,EF(F =27. 240,P ＜ 0. 01 ) were all significantly different among all postoperative MSCT scan except EDV ( F = 2. 339, P =0. 079). Infarct size, which was defined as the proportion of the area of infarction to that of the entire heart,were (39.4 ±12.6)% for MSCT,(37.2 ± 10.0)% for MRI, (35.9 ±9.6)% for TTC, respectively.There were no significant differences of infarct size between TTC and MSCT (t =0. 612, P =0. 574), TTC and MRI (t=0.820, P=0.458), MSCTand MR (t=0. 425 ,P =0. 692 ). Conclusions MSCT,MRI and SPECT were all able to be used to detect the myocardial infarction in acute myocardial ischemia model The infarct size defined on MSCT, MRI and pathology were consistent. The density of ischemic myocardium and cardiac function did not change over the time within 24 h right after infarction.
