[Summary] According to the cutpoint of plasma triglycerides concentration ≥ 1.7 mmol/L,waist circumference ≥85 cm in men or ≥80 cm in women,459 patiens with type 2 diabetes mellitus were divided into four groups:normal waist circumference and triglycerides,normal waist circumference and hypertriglyceridemia,abdominal obesity and normal triglycerides,and hypertriglyceridemic-waist (HTWC) group.The results showed that body mass index,waist circumference,systolic blood pressure,triglycerides,microalbuminuria,and homeostasis model assessment insulin resistance index (HOMA-IR) in HTWC group were higher than those in non-HTWC groups (all P＜0.01),as well as higher diabetic nephropathy incidence (P＜0.05).Multiple logistic regression analysis revealed that HTWC was an independent risk factor of diabetic nephropathy (OR =2.070,95 ％ CI 1.195-3.586).

3T3-L1 adipocytes transfected with TSH receptor (TSHR) shRNA were incubated with bovine TSH.The concentration of tumor necrosis factor (TNF)-α in culture medium was measured by enzyme linked immunosorbent asssy.Protein level of insulin receptor substrate 1 (IRS-1) was quantified by Western blotting.Tyrosine phosphorylation of IRS-1 was measured by immunoprecipitation.The results showed that 1 mIU/ml TSH significantly sitmulated TNF-α release in 3T3-L1 adipocytes [(341.85 ± 12.00 vs 522.67 ± 36.22) ng/L,P＜0.01],along with the decreases in IRS-1 protein expression and its tyrosine phosphorylation (P＜ 0.01).These effects disappeared when TSHR expression was down-regulated with RNA interference in 3T3-L1 adipocytes.In addition,WP9QY,a TNF-α antagonist,blocked TSH-decreased IRS-1 expresssion.These results suggest that TSH downregulates IRS-1 protein expression and its tyrosine phosphorylation through stimulating production of TNF-α,and thus contributes to the development of insulin resistance.

Objective: To investigate the roles of Bcl-xl and Bcl-xs in the development and progression of endometrial carcinoma, and to explore their correlation.Methods: The expression of Bcl-xl and Bcl-xs in 32 cases of endometrial carci-noma, 12 cases of endometrial atypical hyperplasia, 6 cases of endometrial simple hyperplasia and 10 cases of normal en-dometrial tissues were examined by RT-PCR and Western-blot.Results: The expression of Bcl-xl mRNA and protein was significantly higher in endometrial cancer tissues than in normal endometrial tissues (P<0.05), and was statistically associat-ed with the pathological stage of endometrial carcinoma.(F=5.33, P=0.02).The expression of Bcl-xs mRNA and protein in atypical endometrial hyperplasia and endometrial carcinoma tissues were significantlly lower than that in normal endometri-al tissues (P<0.05), which was also associated with clinical stage and lymph node metastasis of endometrial carcinoma (P<0.05).The expression of Bcl-xl was negatively correlated with the expression of Bcl-xs in different endometrial tissues (r=-0.76).Conclusion: The abnormal expression of Bcl-xs and Bcl-xl was a factor for the pathogenesis and development of endometrial carcinoma.The negative correlation between Bcl-xl and Bcl-xs in different endometrial tissues as well as their relative expression ratio may have certain impact on the genesis of endornetrial cancer.

Objective:To investigate the changes of blood pressure and heart rate in patients aged over 80 years undergoing intravitreal injection of anti-vascular endothelial growth factor(VEGF)drugs under topical anesthesia without anesthetic monitoring in ophthalmology surgery, and to analyze the potential risk for surgery-induced acute cardiovascular and cerebrovascular events.Methods:This was a prospective observational cohort study.A total of 100 patients(aged 80 to 95 years, 47 males and 53 females)included 85 cases of wet age-related macular degeneration, 14 cases of retinal vein occlusion with macular edema, and 1 case of diabetic macular edema.These patients received anti-VEGF drugs injection, with accumulated injections of 1 to 36 times per patient.Blood pressure and heart rate were measured at visit to a medical clinic(as baseline), before operation, 0 min and 30 min after operation.The operation anxiety and pain scores were investigated by questionnaires.Comparison of systolic blood pressure, diastolic blood pressure and heart rate among four different time points was performed by Wilcoxon symbol rank test.Results:At four different time points i. e.at the baseline, before injection, 0 min and 30 min after injection, systolic blood pressure, diastolic blood pressure and heart rate showed an important regularity.The median systolic blood pressure at the four time points was 130(120-140)mmHg(1 mmHg=0.133 kPa), 142(129-149)mmHg, 153(139-164)mmHg and 143(130-151)mmHg, with ranges of 100-160 mmHg, 106-176 mmHg, 118-197 mmHg and 115-187 mmHg, respectively.The median diastolic blood pressure at the four time points was 70(65-75)mmHg, 76(69-83)mmHg, 81(73-87)mmHg and 75(69~81)mmHg, with ranges of 45-90 mmHg, 55-98 mmHg, 58-99 mmHg and 50-93 mmHg, respectively.The median heart rate at the four time-points was 70(65-80)beats/min, 72.5(65-81)beats/min, 73(66-80)beats/min and 70(65-76)times/min, with ranges of 50-95 beats/min, 48-101 beats/min, 51-93 beats/min and 50-87 beats/min, respectively.Systolic blood pressure and diastolic blood pressure were significantly increased from preoperative time to 0 min and 30 min after operation( P<0.01). Compared to the baseline, heart rate was increased before operation( P<0.01)and was decreased at 30 minutes after operation( P<0.01). Conclusions:Blood pressure fluctuation may exceed the safe range with an obvious increase of systolic blood pressure during the current intravitreal injection of anti-VEGF drugs in the patients aged over 80 years.Systolic blood pressure rises significantly before operation and falls back after operation, but it may last till 30 minutes after operation.The range of heart rate change is relatively small.Perioperative management and monitoring measures should be strengthened to reduce the risk of acute cardiovascular and cerebrovascular events.

Objective To evaluate the benefits and potential adverse effects of Cordyceps sinensis as an adjuvant immunosuppressive treatment in acute kidney injury.Methods English language database ( including MEDLINE, EMBASE and CENTRAL) in systematic review searched, using search terms relevant to this review.Chinese language databases ( including CNKI, CBM, WanFang and other resources) in systematic review also searched.It included all randomised controlled trials ( RCTs) and quasi-RCTs evaluating the benefits and potential side effects of Cordyceps sinensis for acute kidney injury, irrespective of blinding or publication language.An inclusion criterion was that immunosuppressive therapy baseline must be the same across arms in each study.Data were collected and analyzed by RevMan 5.0.Methodological risk of bias was assessed using the Cochrane risk of bias tool. Results This review included 7 RCTs (representing a total of 601 patients with acute kidney injury) that assessed the use of Cordyceps.Reporting of methods was incomplete in most studies.It conducted comparisons of Cordyceps versus no treatments on the base of same conventional treatment in both groups.Cordyceps for patients showed a favorable trends toward improving patient survival and reducing renal replace treatment, but the difference did not reach significance.However, Cordyceps significantly reduce the level of serum creatinine shorten the period of oliguria, and increase the osmotic pressure of urine.Conclusion On the base of same conventional treatment in both groups, compared with no treatment, Cordyceps significantly improves the functions of renal tubule and glomerulus.But long-term studies are needed to clarify any benefit-harm trade-off.Future studies also need to be appropriately sized and powered.

Objective To investigate the expression levels and the roles of heme oxygenase-1(HO-1) in rat kidney after interruption of blood flow and the following ischemia-reperfusion(IR)injury.Methods Rats were divided into 3 groups: interruptions(5,15,30 min),IR group(2,5,8,24,48,72 h),and control group.They were killed at different time points.Kidney tissue samples were studied by immuneohistochemical method.Results The expressions of HO-1 raised significantly in both ischemia group of 30 min((P

Objective To illustrate the expressional distribution of heat shock protein 70(HSP 70) in the kidney of acute renal injury rats caused by gentamicin.Methods One hundred and fifty rats were randomly divided into 3 groups: group A (normal group), group B [80 mg/(kg?d) gentamicin to be injected], group C [160 mg/(kg?d) gentamicin to be given]. The variations of renal pathology were observed at different time phasess by light scope and electromicroscope. Simultaneously, the expression of HSP 70 in kidney was evaluated by immunohistochemistry.Results HSP 70 distributed in epithelial cells of renal tubular in acute injury rats. The expression of HSP 70 increased markedly from the 6th hour after injection, peaked at the 12th hour and lasted for 48 hours. The expression of HSP 70 in group C was higher than that in group B(P

Objective To discuss the relationship between serum 25-hydroxy vitamin D[25(OH)D] level and the severity of diabetic retinopathy in type 2 diabetes mellitus.Methods 1474 cases of type 2 diabetic patients were classified into three groups according to their severity of diabetic retinopathy, the non-diabetic retinopathy group(NDR group, n =640), the background diabetic retinopathy group(BDR group, n =494) and the proliferative diabetic retinopathy group(PDR group, n=340).640 healthy people with normal level of glycosylated hemoglobin(HbA1c) were selected as control group(NDM group, n=640).Disease duration, body mass index(BMI), systolic pressure, low density lipoprotein-cholesterol(LDL-C), HbA1c and 25(OH)D were detected and compared among groups.Results Disease duration and HbA1c were increasing significantly, and the levels were NDM groupNDR group>BDR group>PDR group(all P<0.05).The level of 25(OH)D was negatively related to disease duration and HbA1c (P<0.001), and it was negatively associated to the severity of diabetic retinopathy(r=-0.855,P<0.001).Conclusion The decrease of 25(OH)D level is closely associated with the severity of diabetic retinopathy in patients with type 2 diabetes mellitus, and it might be an important predictor for the severity of diabetic retinopathy.
