Chinese Journal of Geriatrics 2012;31(6):491-494
Objective To investigate the blood glucose control level,the characteristics of complications and treatment programme in senile patients with type 2 diabetes.Methods From Aug 2010 to Jul 2011,gender,age,height,weight,disease course and underlying disease were recorded in 119 patients with type 2 diabetes aged 80 years and over.The levels of glycosylated hemoglobin (HbA1c),fasting C-peptide (FC-P) and 2 hours postprandial C-peptide (2h C-P),urinary albumin excretion rate (UAER) were tested.Ultrasonic Doppler examination of lower-limb arteries as well as non-mydriatic colour eye-ground photography were also examined,peripheral nerve lesions were evaluatcd according to the criteria of diabetic neuropathy system (DNS).The patients were divided into two groups:HbA1c<7.0% group (65 cases) and HbA1c ≥ 7.0 % group(54 cases).Results The disease course[(12.1±8.5)years vs.(16.6±7.5)yeas,t=3.01,P=0.003],UAER[(20.2±11.9)μg/min vs.(47.0±21.4)μg/min,t=2.48,P=0.015] and incidence of diabetic nephropathy [23.1%(15/65)vs.50.0%(27/54),x2=9.36,P=0.002] were all less in HbA1c<7.0% group than in HbA1c ≥ 7.0% group,while the levels of FC-P and 2hC P were higher in HbA1c<7.0%than in HbA1c ≥ 7.0% group[(2.1±1.2)μg/L vs.(1.5±1.0)μg/L,t=1.87,P=0.042; (6.5± 3.3)μg/L vs.(4.3 ± 2.9) μg /L,t =2.10,P =0.037].The proportion of patients who took oral hypoglycemic agents was increased while those who received insulin therapy decreased in HbA1c<7.0% group (all P=0.000).The α-glucosidase inhibitors were the most commonly used in each group,followed by metformin and insulin secretagogue,and the thiazolidinediones were rarely used,while there was no significant difference in the proportion of medicine between the groups.The overall incidence of symptomatic hypoglycemia was 23.5%(28/119).It was higher in HbA1c ≥ 7% group than in HbA1c<7.0% group[33.3%(18/54)vs.15.4%(10/65),x2 =5.20,P=0.022].However,71.4%(5/7)of the patients with hypoglycemic coma came from HbA1c<7.0% group.Conclusions There are obvious individual differences in blood glucose control and complications among senile type 2 diabetes patients,thus the characteristics of the elderly should be considered in the choice of drugs while hypoglycemic events should be paid more attention.
3.Tie2 expressing monocytes in cancer research
Journal of International Oncology 2013;40(8):579-581
Tie2 expressing monocytes (TEMs) only present in human circulating blood and tumor organs,and have an important role in tumor angiogenesis and progression.TEMs are effectively recruited to tumors by angiopoietin 2 (Ang2) and hypoxia and then differentiate into macrophages,which promote the angiogenesis in experimental tumor models by providing paracrine support to nascent blood vessels.Studies show that TEMs are up-regulated in hepatocellular carcinoma,colorectal cancer,breast cancer,malignant glioma and other human cancers,which suggests that TEMs are conducive to diagnosis and prognosis of tumors.With the further research,TEMs are applied to deliver drugs which can obtain significant anti-tumor responses and inhibit metastasis with the ability of tumor-homing.Meanwhile,TEMs may also be a potential target for the anticancer drugs.However,the present researches indicate that the effects of TEMs in tumor microvessel density,clinical stage and prognosis are still questionable.Current works that aim at describing and predicting the concrete function of TEMs have attracted significant attention from researchers.
4.Prevention, Diagnosis and Treatment of Biliary Tract Complications after Liver Transplantation
Chinese Journal of Bases and Clinics in General Surgery 2003;0(03):-
Objective To investigate the causes of biliary tract complications after liver transplantation, and to put forward effective measures of prevention, diagnosis and treatment. Methods The literatures of recent years were reviewed and summarized. Results The causes of biliary tract complications after liver transplantation are very complex, and there are no standard preventive measures. Treatment differs according to causes. Conclusion One of the most important causes leading to biliary complications is preservative and ischemic injury. Poorly operative techniques and blood supply to biliary tract are also disastrous. Improving T tube placement can reduce the incidence of biliary complications related with T tube. To prevent biliary complications, it is crucial to completely wash the biliary tract, avoid damaging the blood supply to donor biliary tract and manage perfect biliary mucosa-to-mucosa anastomosis without tension. T tube cholangiography combined with noninvasive MRCP enables accurate depiction of the biliary tree and diagnosis of biliary complications. Doppler ultrosonography should be routinely applied postoperatively. Timely application of interventional radiological technique is a valuable nonoperative procedure for treatment of biliary complications. Meanwhile, biliary sludge or cholestasis and mixed infections of biliary tract should be handled actively and properly.
5.Polysaccharidical peptides augmented the functions of tumour infiltrating lymphocytes
Chinese Journal of Pathophysiology 1986;0(02):-
The effects of polysaccharidical peptides (PSP) on the functions of tumour infiltrating lymphocytes (TILs) in vitro was explored. The results showed that PSP, at the concentration of 37-1200?g/ml, promoted the proliferation of TILs in dose-related manner. Combination of PSP with interleukin-2 (IL-2) enhanced the cytotoxicity of TILs and reduced the dose of IL-2 used for activating TILs. The results suggested that PSP could augment the proliferation and cytotoxicity of TILs in vitro.

Chinese Journal of Geriatrics 2011;30(1):38-41
Objective To investigate the effect of seasonal variation of blood pressure (BP) on the incidence of cardiovascular and cerebrovascular events in the elderly aged 80 years and over.Methods The 67 patients (aged 80-86 years) with essential hypertension were enrolled, the BP were measured at home, in consulting room, and by 24-h ambulatory BP monitor in every season for 2 years. The incidences of cardiovascular and cerebrovascular events were recorded in the meantime.Results Both systolic BP (SBP) and diastolic BP (DBP) were lower in summer than in any other season (P<0. 01 ). SBP was higher in winter than in any other season. (P<0.01), DBP was higher in winter than in summer(P<0. 01). There were no significant differences in SBP and DBP between spring and autumn. The incidence of cardiovascular and cerebrovascular events were higher in winter and summer than in spring and autumn (P<0.05). The season (OR= 1. 525, P=0. 001), BMI (OR =1.145, P=0.018) and heart function (OR= 2. 037, P=0.01) were related to the incidence of cardiovascular events. And the season (OR = 1. 604, P= 0. 001 ), history of cerebrovascular disease (OR= 1. 598, P=0. 034), office-measured SBP (OR=0.960, P=0.013) and ambulatory DBP (OR =0. 936, P = 0. 008) were related to the incidence of cerebrovascular events.Conclusions The blood pressure measured by three methods in the elderly aged 80 and over shows that both SBP and DBP are at the lowest in summer; SBP is at the highest in winter, DBP is higher in winter than in summer. There are no significant differences in BP between spring and autumn. The incidences of cardiovascular and cerebrovascular events are significantly higher in winter and summer than in spring and autumn.
9.Evaluation on short-term prognosis of hepatitis B patients with acute-on-chronic liver failure using MELD and PT
Chinese Journal of Clinical Infectious Diseases 2008;1(4):207-209
Objective To compare the model for end-stage liver disease (MELD) and PT in survival prediction of hepatitis B patients with acute-on-chronic liver failure. Methods One hundred and thirty-nine hepatitis B patients with acute-on-chronic liver failure were divided into survival and death group, and evaluated by MELD and FT. The area under ROC curve was used to compare the MELD and PT. The mortality was observed within 3 months. Results The MELD score and PT of survival group was 25.09 ± 3.92 and (26.46 ± 6.46) seconds respectively, and those for the death group were 36.25 ± 6.42 and (40.78 ± 10.80) seconds. The differences were of statistical significance ( P < 0.01 ). MELD score showed significant correlations with PT(r =0.824, P <0.01). The area under ROC curve was 0.936 (95% CI 0.895 ± 0.977 ) on MELD score and 0. 890 (95 % CI 0.839 ± 0.941 ) on PT, and there was no significant difference between them. Conclusions Both MELD score and PT can accurately predict the short-term prognosis of hepatitis B patients with acute-on-chronic liver failure. The validity of prognosis by MELD is similar to PT. The mortality increases with the MELD score and PT increasing.
