To explore the relationship between serum resistin concentration, hypertension, degree of obesity and blood glucose, fasting serum resistin concentration was measured with EIA in 17 normotensives and 44 patients with essential hypertension. Serum resistin concentration was significantly correlated with age and body fat percectage (BF%). The concentration level was significantly higher in grade 2 hypertension group [(30.5?11.0)?g/L] than in grade 1 hypertension group [(24.3?10.5)?g/L] and in normotensives group [(21.5?6.1)?g/L]. The difference in serum resistin concentration between the three groups disappeared when age and BF% were corrected by analysis of covariance. Serum resistin concentration was significantly correlated with systolic blood pressure, age, BF%, fasting plasma glucose. A stepwise multiple linear regression analysis revealed that age, BF% and fasting plasma glucose were significantly independent predictors of serum resistin concentration. The results suggest that serum resistin concentration is not directly related to blood pressure, but the concentration level is actually correlated with age, BF% and glucose metabolism.

Objective To investigate the effect of obesity on change of the levels of blood glucose and blood lipid after treatment with different combinations of antihypertensive drugs in patients with essential hypertension (EH). Methods One hundred and thirty-eight patients with mild to moderate EH were randomly divided into 3 groups with different combinations of drugs: reserpine with dihydralazine, hydrochlorothiazide, potassium chloride group (group 1), fosinopril with indapamide group (group 2), and nifedipine with atenolol group (group 3). Treatment period lasted for 14 months. Every group was divided into obesity subgroup and non-obesity subgroup according to Chinese obesity standard. Results After treatment, blood glucose levels were significantly decreased and blood lipid level was unchanged in both obesity subgroup and non-obesity subgroup of group 1. High density lipoprotein-cholesterol (HDL-C)/low density lipoprotein-cholesterol (LDL-C) ratio was significantly decreased and blood glucose was significantly increased in obesity subgroup, however, there was not significant change in the level of blood glucose and blood lipid in non-obesity subgroup of group 2. Blood glucose level was significantly increased and HDL-C/LDL-C ratio was significantly decreased in obesity subgroup, however, there was significant increase only in fasting blood glucose in non-obesity subgroup of group 3. Conclusions The results suggested that treatment with a combination of reserpine and dihydralazine, hydrochlorothiazide, potassium chloride showed beneficial effect on improving carbohydrate metabolism in both obese and non-obese patients with EH, while the treatment with the combination of fosinopril with indapamide deteriorated carbohydrate and lipid metabolism in obese patients with EH, and the treatment with combination of nifedipine with atenolol impaired carbohydrate and lipid metabolism in obese patients with EH.

Objective To compare the treatment outcomes between minimally invasive perventricular device occlusion (MIPDO) and right subaxillary incision surgical repair(RSISR) on perimembranous ventricular septal defect(PmVSD) in children less than 15 kilograms.Methods From January,2010 to January,2013,a total of 530 infants(age ＜ 3 years,weigh ＜ 15 kg) with PmVSD enrolled and they were divided into two groups according to different treatment methods at random.Group 1 (265 cases) was arranged perventricular device closure with modified occluders through a lower partial median sternotomy under transesophageal echocardiography (TEE) guidance;group 2 (265 cases) was arranged surgical repair on cardiopulmonary bypass(CPB) through a right subaxillary small incision.A prospective randomized controlled study was performed between two groups on success rate,operation time,volume of blood loss and transfusion,length of intubation and ICU stay,complications,expenses and follow-up results etc.Results All patients in two groups obtained effective treatment with no death or serious life-threatening complications.Group 1:255 cases (96.23％) underwent successfully MIPDO.The remainder 10 cases (3.77％) who failed in attempt were successfully converted to conventional open heart operation by extending the original incision.Different arrhythmias arose in 30 cases(11.76％),including incomplete left bundle branch block(ILBB) in 3 cases(1.18％),complete right bundle branch block(CRBB) in 3 cases(1.18％),incomplete right bundle branch block(IRBB) in 16 cases(6.27％),Ⅰ° atrioventricular block(Ⅰ°AVB) in 8 cases(3.14％);trivial residual shunt(RS) in 18 cases(7.06％);newly arose trivial tricuspid regurgitation(TR) in 29 cases(11.37％).Group 2:All the patients(100％) underwent successful surgical repair through right subaxillary incision.Different arrhythmias occurred in 116 cases (43.77％),including transient complete atrioventricular block(CAVB) and ILBB in 2 cases respective(0.75％),junctional ectopic tachycardia(JET) in 1 cases(0.38％),CRBB in 61 cases(23.02％),IRBB in 52 cases(19.62％);trivial RS in 16 cases (6.04％);newly arose trivial TR in 11 cases(4.15％);heart dysfunction in 17 patients(6.42％).All patients were followed up for more than 12 months,and there were no newly happened or aggravated valve regurgitation or late onset CAVB in two groups.The final treatment effects are similar in both groups.But group 1 was significantly superior to group 2 in the aspects of operation time,volume of blood loss and consumption,length of intubation and ICU stay,hospitalizations and costs(all P ＜ 0.05).The incidence of TR is higher in group 1 (P ＜ 0.05),and that of right bundle branch block was higher in group 2 (P ＜ 0.05).The incision is longer in group 2,but in a less exposed location.CPB is not needed in group 1,but anticoagulant drug is required for 3-6 months.Conclusion Both RSISR and MIPDO are effective treatment methods of PmVSD.Though having some limitations,MIPDO which characterized by simple procedure,minimal invasion,quick recovery,saving of medical resources could not only minimize the surgical trauma to patients,but also ensure the safety of operation to the maximum extent.However,the patient selection is vital.For selected patients,especially those of moderate PmVSDs with obvious clinical symptoms but no cardiac valve regurgitation,it is an ideal approach.

Objective: To investigate the rifampicin resistance status and its influencing factors among elderly patients with pulmonary tuberculosis in Changzhou City, Jiangsu Province, so as to provide the basis for improving drug-resistant pulmonary tuberculosis prevention and control strategies. Methods: Patients aged over 60 years with pulmonary tuberculosis treated in tuberculosis designated hospital was selected. Demographic information, history of previous disease, history of diagnosis and treatment and drug sensitivity test were collected. Rifampicin resistance among elderly patients with pulmonary tuberculosis and its influencing factors was analyzed. Results: Totally 249 elderly patients with pulmonary tuberculosis were included, with an average of (69.75±4.36) years. There were 147 males and 102 females, with a gender ratio of 1.44∶1. There were 183 treatment-naïve patients (73.49%) and 66 retreated patients (26.51%). Rifampicin resistance was found in 21 cases, with a drug resistance rate of 8.43%. Among them, there were 7 treatment-naïve patients (3.83%), and 14 retreated patients (21.21%). Multivariable logistic regression analysis showed that retreated elderly patients with pulmonary tuberculosis had a higher risk of rifampicin resistance (OR=10.551, 95%CI: 1.344-82.857). Conclusion The rifampicin resistance rate of 249 elderly patients with pulmonary tuberculosis was 8.43% and was associated with the type of treatment.

Objective To explore the efficacy and safety of low-dose ketamine for prevention of shivering during cesarean section under subarachnoid space and epidural anesthesia.Methods Ninety pregnant women who scheduled cesarean delivery under subarachnoid space and epidural anesthesia were randomized divided into three groups:control group (30 patients) low-dose ketamine group (30 patients) and high-dose ketamine group (30 patients).0.9％ sodium chloride,0.25 mg/kg(3 ml),and 0.50 mg/kg (3 ml) ketamine were given in three groups before operation.The incidence of shivering and adverse effect were recorded respectively before anesthesia,after anesthesia 15 min and 30 min and after operation 1 h.Results The level of mean arterial pressure (MAP) in control group after anesthesia 15 main and 30 min and after operation 1 h[(62 ± 10),(58 ± 8),(61 ± 11) mm Hg(1 mm Hg =0.133 kPa)] were significantly lower than those in high-dose ketamine group [(78 ± 12),(82 ± 8),(76 ± 11)mm Hg] and low-dose ketamine group [(72 ± 10),(76 ± 6),(80 ± 7) mm Hg],there was significant difference (P ＜ 0.05).There was no shivering need treat in low-dose ketamine group and high-dose ketamine group.The rate of hallucinations and nystagmus in low-dose ketamine group [0,6.7％ (2/30)] was significantly lower than that in high-dose ketamine group [20.0％ (6/30),50.0％ (15/30)],there was significant difference (P ＜ 0.05).Conclusion The pretreatment with low-dose ketamine on shivering during cesarean section under subarachnoid space and epidural anesthesia has better preventive effectiveness,0.25 mg/kg of ketamine is more effective than 0.50mg/kg.

Objective:To investigate the influence of chronic kidney disease(CKD),including slight renal damages,on prognosis of coronary artery disease(CAD).Methods: A retrospective study was performed in 732 patients who visited our Cardiology Department and Cardiothoracic Surgery Department in 2000-2004.All patients suspected of CAD underwent a selective coronary angiography.Five hundred and seventy-nine patients with established diagnosis of CAD were followed up and their cardiovascular events(angina pectoris,myocardial infarction,recurrent myocardial infarction,heart failure,stroke,death,etc.) were recorded.Patients with CAD were divided into normal,slight,moderate,and severe groups according to the degree of renal function damages.The influences of different degrees of renal damages on the prognosis of CAD were compared.Results: There were obvious differences in the morbidities of angina pectoris,myocardial infarction,recurrent myocardial infarction,heart failure,stroke,etc.in CAD patients with different degrees of renal function damages.The worse the renal function,the higher the incidences of angina pectoris,myocardial infarction,recurrent myocardial infarction,heart failure and stroke,etc((P

BACKGROUND:There are numerous studies on bone marrow mesenchymal stem cells(BMSCs)from small animals such as rats and rabbits,but no few reports addressing BMSCs from big animals.OBJECTIVE:To observe in vitro cultured goat BMSCs,and to understand its biological properties.METHODS:A healthy Chinese goat aged ten months was obtained to extract 5 mL fresh bone marrow from the posterior superior iliac spine by puncture following anesthesia.Using the whole bone marrow method,the samples were incubated in a sterile plastic culture flask and added with DMEM/F12 containing 10% fetal bovine serum.Following 80% 90% confluence,cells were digested by trypsin.Cells at passage 3 in logarithmic phase were collected and frozen,and then recovered.Changes in cell morphology were observed using an inverted microscope.Cell growth curve was measured using MTT assay.The potential of osteogenic differentiation was examined utilizing Von Kossa's staining.RESULTS AND CONCLUSION:The primary cultured BMSCs were cultured with adherent growth.The cells were spindle form.Cell morphology following passage 3 was similar,showing long spindle shape.Following freezing and recovery,cell adherence was slower compared with subculture cells,and no significant difference was detected in cell morphology and viability compared with subculture cells.Growth cycle was similar in passage 3-passage 5 cells.BMSCs entered lag phase at days 2 and 3,logarithmic phase at day 3,and platform phase at days 6 and 7,and then growth speed was slow.Goat BMSCs were positive for Von Kossa's stain at 3 weeks following osteogenic induction.Results verified that cultured goat BMSCs showed strong genetic stability and proliferation ability,and differentiated into osteoblasts.

Iron uptake mechanism of Vibrio alginolyticus was primarily investigated. V.alginolyticus could survive in the medium with high-concentration iron chelator. The strain of V. alginolyticus isolated from diseased fish produced more siderophore than that from marine environment. The extract of siderophore from V. alginolyticus could stimulate the growth of Escherichia coli mutant AN93. Under iron limitation,the growth rate was decreased and several outer membrane proteins were induced. Adding iron into the iron-limited medium the normal growth could be recovered.
