Objective The insulin pathways within ovary are in close relationship with female reproductive ability .The arti-cle was to observe the effects of ovarian insulin resistance on ovarian function and the effects of cryptotanshinone (CRY) on ovarian in-sulin resistance. Methods All mice were randomly divided into saline group (isotonic saline), DEX a group (isotonic saline plus DEX), CRY a group(isotonic saline plus DEX plus cryptotanshinone ), 10 in each group.The degree of insulin resistance was tested on each rat, along with the measurement of disintergrations per minute (DPM), ovulation rate and serum hormone level .After 20 fe-male mice were put to death , their ovaries were randomly divided into 4 groups:blank control group ( blank culture solution ) , DEX b group (DEX), CRY b group(DEX plus cryptotanshinone ), and WT group (DEX plus cryptotanshinone plus wortmannin ), 8 in each group. Murine ovaries in each group were cultured in vitro to test the number of ovarian glucose and the serum hormone level . Results After in-
sulin resistance took place in murine ovaries , significant statistical difference was found between DEX a group and saline group as to 2-deoxy-D-[1,2-3H]-glucose, liver, adipose and ovarian tissues (P<0.05).Ovaries in CRY a group increased significantly compared with DEX a group([2805.2 ±921.5]DMP/mg vs [1183.2 ±382.2]DMP/mg, P<0.01 ).Compared with DEX a group(37.5 ± 7.0, 5.0 ±1.8), the ovulation rate and the average corpus luteum in saline group (26.3 ±5.9, 3.5 ±1.6) and CRY group (27.2 ± 6.3,3.8 ±0.9) decreased (P<0.05).In comparison to DEX a group, the estrogen and progestogen levels in saline group and CRY a group decreased significantly(P<0.05).The expression level of AKT2 protein in DEX a group was much lower than that in saline group([0.39 ±0.01] vs [0.77 ±0.03], P<0.05).The glucose uptake in ovarian tissues cultured in vitro in blank control group , DEX b group, CRY b group and WT group was respectively (3447.2 ±1245.2)DMP/mg, (1183.2 ±382.2) DMP/mg, (2805.2 ± 921.5) DMP/mg, and (1364.2 ±292.3) DMP/mg.DEX b group decreased significantly compared with blank control group , DEX b group and WT group decreased significantly in comparison to CRY b group (P<0.05).In comparison to blank control group, the me-dium testosterone level increased and the protesteron level decreased significantly in DEX b group (P<0.05). Conclusion Tradi-tional Chinese medicine cryptotanshinone can relieve ovarian insulin resistance in vitro and in vivo , and it may exert insulin sensitivza-tion through PI3K pathway.

Objective To analyze the occurrence and prognosis of congenital heart disease interventional therapy related arrhythmias, and to discuss the prevention and treatment. Methods We retrospectively analyzed the occurrence and prognosis of congenital heart disease interventional therapy related arrhythmias among a total of 223 cases admitted for in terventional therapy between February 2014 to January 2015. Resu1ts 8 cases developed different degree and nature of arrhythmias after the interventional therapy. Among these cases, 3 of them had arrhythmias after ASD occlusion, including one was frequent atrial contraction, one was paroxysmal atrial tachycardia, and one was sinus bradycardia with accelerated junctional rhythm. All of them converted back to sinus rhythmm spontaneously from 2-3 hours to maximum 1 week after operation. 4 cases had arrhythmias after VSD occlusion, including one case of ventricular tachycardia, one case of Ⅰ° degree atrioventricular block who recovered spontaneously after surgery, one case of Ⅲ° degree atrioventricular block and one case of intermittent complete left bundle branch block who retruned to sinus rhythmn after 1 week of symptomatic treatment. One case had ventricular fibrillation after pulmonary valve balloon dilatation and was treated by defibrillation and temperany pacing to convent to sinus. Conc1usions Arrhythmias is a common complication of congenital heart disease after interventional therapy, and most of them are temporary and transient changes. However, once serious arrhythmias happened, the success rate of surgery and postoperative curative effect can be directly effected, or may even lead to mortality.

Objective To compare main adverse cardiac events of patients with coronary heart disease and diametes,but normal lipids after statin on lowering lipids , and to bring out necessity of early lowering lipids . Methods A total of 324 patients with coronary heart disease and diametes were enrolled ,LDL-C was measured in-hospital for all patients and LDL-C<3.36mmol/L suitable for the experiment .They were divided into statin group (n=176,rosuvastatin 10 mg/d)and control group(n=148)randomly,all patients received second prevention for cor-onary heart disease including anti-platelet,anti-myocardial ischemia,smoke quitting,adjust diets and exercise,the CAG or PTCA(and stent implanting),CABG.the end events were main adverse cardiac events (cardiac events,recur-rent angina and target vessel reconstruction ).The mean follow-up time was(13 ±6)months.Results The fasting plasma glucose,LDL-C,hs-CRP in statin group were all significantly lower than those of control group [FPG:(5.3 ± 0.9)vs.(6.7 ±1.2)mmol/L,P=0.042;LDL-C:(1.7 ±0.6)mmol/Lvs.(3.9 ±1.6)mmol/L,P<0.01;hs-CRP:(1.4 ±0.5)mmol/L vs.(3.8 ±1.2)mg/L,P <0.01],MACE were less(15.6% vs.37.1%,P =0.032). Conclusion Early statin on patient with coronary heart disease and diametes ,though normal lipids ,which can down-regulate main adverse cardiac events significantly .

For decades,there have been no systematic studies on the reference intervals of Chinese populations.With the support of the Ministry of Health,the Chinese Society of Laboratory Medicine launches a research project investigating the Chinese reference intervals for common clinical laboratory tests.Up to now,the first batch of reference intervals for common liver function,electrolytes and blood cell analysis have been published in forms of healthy professional standards.Medical institutions are suggested to use these new reference intervals in clinical practice.

Objective To investigate the changes of peripheral blood tacrolimus concentration and lymphocyte subsets in the uterus transplant recipient,and provide the evidence for monitoring the immune status after uterus transplantation.Methods The peripheral blood tacrolimus concentrations of the uterus transplant recipient during 1 year after transplantation were measured with the microparticle enzyme immunoassay (MEIA).Meanwhile,the whole blood cell counts and lymphocyte subsets were determined by the blood analyzer and flow cytometer,respectively.Results The blood tacrolimus concentrations of the uterus transplant recipient in the first month and second month after transplantation were (13.51 ± 3.92) ng/mL and (15.58 ± 1.19) ng/mL,respectively.The lymphocyte absolute counts were normal before transplantation.At the fifth day after transplantation,the counts of CD3 + T lymphocytes,CD4 + T lymphocytes,CD8 + T lymphocytes and NK cells and the ratio of CD4/CD8 were significantly decreased.One week after transplantation,the counts of CD4 + T lymphocytes were recovered to the normal range and maintained,but its recovery was slower than that of CD8 + T lymphocytes.The ratio of CD4/CD8 ranged from 0.4 to 0.8 during 10 days after transplantation,and increased and maintained between 0.8 and 1.1 after that.The counts of NK cells increased gradually from the 10th day after transplantation,but still did not recover to the level before transplantation even at the 20th day after transplantation.However,the counts and percentages of B lymphocytes did not decrease but increased at the fifth day after transplantation,and recovered to normal gradually from the 10th day after transplantation.There was no significant correlation between the CD3 + T lymphocyte count and blood tacrolimus concentration.Conclusion The dynamic changes of blood lymphocyte subsets and tacrolimus concentration exist in the uterus transplant recipient,which need to be further verified by a large amount of clinical data.
