Objective To investigate the influences of mutation at precore and basic core promoter(BCP) region in hepatitis B virus(HBV) on the immune response of specific cytotoxic T lymphocytes(CTL) in patients with chronic hepatitis B(CHB).Methods The number of specific CTL in peripheral blood mononuclear(PBMC) of CHB patients were tested by cytokine flow cytome- try(CFC) and HBV core18-27 peptide.HBV precore and BCP fragments were directly sequenced. Results Twenty-one(38.9%) samples were HBV precore G1896A mutation.Twenty-six(48.1%) samples were BCP region 1762/1764 combined mutation.Thirteen(24.1%) stains were three sites mutated simultaneously.Stimulated with HBV core 18-27 in vitro,the specific CTL level was signifi- cantly higher in the patients with G1896A mutation and BCP region mutation [(0.41?0.09)%, (0.36?0.08)%,(0.48?0.08)%,respectively]than those without mutation[(0.11?0.06)%, P

Objective To evaluate the role of early cleavage embryo in combination with embryo growth rate and morphology scoring in embryo selection in in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles. Methods Six hundred and ten IVF/ICSI cycles were randomly assigned to group A(269 cycles) and group B(341 cycles). In group A, transferred embryos were chosen according to embryo growth rate and morphology scoring by 72 h(D3) after fertilization, while early cleavage embryo was added to the selecting system in group B. The pregnancy rate and implantation rate were compared between two groups, and the clinic outcomes were compared between transfers with early cleavage embryos and without early cleavage embryos in group B. Results The pregnancy rate and implantation rate in group B were significantly higher than those in group A (P < 0.05). Transfers with early cleavage embryos also achieved much higher pregnancy rate and implantation rate in group B (P < 0.01). Conclusion Compared with embryo growth rate and morphology scoring, early cleavage embryo in combination with embryo growth rate and morphology scoring can improve the clinical outcomes in IVF/ICSI cycles.

OBJECTIVESepsis, severe sepsis, and septic shock are frequently encountered and highly lethal conditions among children treated in ICU; however, no many reports on research on serum albumin levels of children under these conditions are available in literature and little is known about the relationship between serum albumin level and prognosis. In this prospective study, the author observed the levels of serum albumin of children with sepsis/severe sepsis/septic shock, and explored the relationship between serum albumin level and severity of illness or prognosis.

METHODFor sepsis/severe sepsis/septic shock patients admitted to the pediatric intensive care unit (PICU) during the year 2008, serum albumin concentration in peripheral blood was examined within 24 h after admission. According to the diagnostic criteria, hypoalbuminemia was defined as serum albumin level of < 35 g/L.

RESULTA total of 247 cases of sepsis/severe sepsis/septic shock children were enrolled. In the order of sepsis/severe sepsis/septic shock group, there were 143, 65 and 39 cases. Overall rate of hypoalbuminemia was 72.9% (180/247). The rate of hypoalbuminemia in children with sepsis, severe sepsis or septic shock was 59.4% (85/143), 86.2% (56/65) and 100% (39/39), respectively. The mortality of hypoalbuminemic patients in sepsis, severe sepsis and septic shock group showed significant difference (P < 0.001). The rates of hypoalbuminemia of the survived cases (69.5%) was significantly lower than that of the non-survived cases (94.1%). Pediatrics critical illness score (PCIS) and serum albumin concentration was positively correlated (P < 0.001), and the mortality was negatively correlated with serum albumin concentration (P < 0.05).

CONCLUSIONHypoalbuminemia is common among children with sepsis/severe sepsis/septic shock and serum albumin level is closely related to prognosis. Serum albumin level monitoring on the basis of PCIS scoring has important clinical prognostic significance in evaluating the prognosis of severe sepsis/septic shock patients.

Objective To evaluate the clinical outcome and relative factors of intervention treatment for atherosclerotic renal artery stenosis in elderly patients.Methods The clinical data of 79 patients diagnosed as atherosclerotic renal artery stenosis by angiography and treated by revascularization were analyzed.Results There were 55(69.6%)successes and 24(30.4%)failures in decreasing blood pressure and 28(35.4%)successes and 51(64.6%)failures in improving renal function after intervention treatment.Predictors of favorable outcome of intervention treatment in decreasing blood pressure were related to lower urine protein,higher glomerular filtration rate,higher systolic and diastolic blood pressure before treatment,lower resistance index(RI)of renal artery,and no complication of cerebral vascular diseases.Predictors of favorable outcome of intervention treatment in improving renal function were related with percentage of angiographic stenosis,category of antihypertension and lower urine protein.The logistic regression analysis showed that the percentage of angiographic stenosis was the most important predictor of intervention treatment for blood pressure control,age and level of serum creatinine before intervention treatment were the most important predictors of intervention treatment for improving renal faction.Conclusion Percentage of stenosis(≥85%),age(133 ?mol/L)can be used as the predictors of therapeutic success for renovascular stenosis in older patients.

Objective Blood pressure variability (BPV) is an independent risk factor for the death of patients with maintenance hemodialysis (MHD).There is no study on the influencing factors of BPV at home in HD patients in China.The article aimed to investigate MHD patients'BPV at home and related influencing factors in order to provide theoretical basis for reducing home BPV (HBPV) clinically. Methods We chose 103 patients who were treated with MHD in the Renal Medicine Room of Nephrology Department in three upper first -class hospitals including Jiangsu Provincial People 's Hospital, the First Affiliated Hospital of Suzhou University and the Affiliated Hospi -tal of Jiangsu University from March 2017 to October 2017.We col-lected their 7 days'blood pressure monitoring at home and blood pressure before dialysis, average value and standard deviation in sys -tolic blood pressure monitoring at home, and took the coefficient of variation of systolic blood pressure as the expression of HBPV .The patients were divided into high BPV group (BPV≥5.8％) and low BPV group (BPV<5.8％) according to the average BPV.At the same time, we recorded indexes such as sex , age, dialysis age, primary disease, BMI, inter-dialytic weight gain (IDWG), left ven-tricular mass index(LVMI) and analyzed relative influencing factors by multiple linear regression . Results The age, IDWG and LV-MI were positive independent influencing factors of HBPV (R 2 =0.467,F=10.945,P<0.001).According to standardized regression co-efficient, the contribution of each variable to HBPV was as follows : PIBWG >Age>LVMI. Conclusion In clinical nursing, we should actively control the IDWG of patients , encourage patients to monitor their blood pressure at home , and increase their awareness of the importance of home BPV.Meanwhile, HBPV is an important index for predicting left ventricular hypertrophy and can be used as an objective tool to improve patients 'self-management ability.

OBJECTIVETo detect the influence of mannitol on cerebral blood flow of post-resuscitation children by transcranial Doppler (TCD).

METHODSThe blood flow changes of left side middle cerebral artery (MCA) and extracranial internal carotid artery (EICA) were monitored by TCD in 21 post-resuscitation children. TCD waveforms, peak velocity (Vp), diastolic velocity (Vd), mean velocity (Vm) and pulsitility index (PI) of MCA and EICA were monitored daily and 30 minutes before and after the first dose of mannitol. Glasgow scores were estimated in the meantime. The patients were divided into 2 groups according to the patterns of diastolic flow. Patients in group I showed no diastolic flow or retrograde diastolic flow (n = 9), and patients in group II had positive diastolic flow (n = 12).

RESULTSVp, Vd, Vm, PI of MCA and EICA in group I patients had no significant change after the administration of mannitol and the Glasgow scores were much lower than that of group II patients (P < 0.05). TCD waveforms showed no improvement in group I patients and their outcomes were poor. Vd, Vm and Vp of MCA and Vd of EICA in group II patients increased, PI of MCA decreased (P < 0.05), while Vp, Vm, PI of EICA had no significant change. TCD waveforms recovered within one week. All the patients in this group survived.

CONCLUSIONSThe results suggested that mannitol could improve cerebral perfusion in patients with mild brain damage. These patients usually had increased diastolic blood flow in the early stage. Lack of or retrograde diastolic flow of TCD waveforms might be associated with severe brain damage with poor outcome. Mannitol had no effect on improving cerebral blood flow in these patients.

A sensitive high performance liquid chromatography-electrospray ionization-mass spectrometry (HPLC-ESI-MS) method was established for the determination of eplerenone (EP) in human plasma. The plasma samples of EP were extracted with ethyl acetate and separated by HPLC on a reversed phase C18 column with a mobile phase of 10 mmol x L(-1) ammonium acetate water solution-methanol (30 : 70, v/v). EP was determined with electrospray ionization-mass spectrometry (ESI-MS) in the selected ion monitoring (SIM) mode. The calibration curves were linear over the range of 2-4 000 ng x mL(-1) for EP. The lower limit of quantification was 2 ng x mL(-1). The method has been successfully applied in the pharmacokinetic study of the EP tablets. The main pharmacokinetic parameters of EP after oral administration of 25 mg, 50 mg, 100 mg were as follows, t1/2: (4.9 +/- 2.1), (4.7 +/- 1.5), (5.9 +/- 1.2) h; AUC(0-infinity): (4 402 +/- 1 735), (8 150 +/- 2 509), (13 783 +/- 4 102) microg x h x L(-1); and MRT: (6.2 +/- 2.1), (6.6 +/- 1.3), and (7.2 +/- 1.6) h. Parameters of EP after oral administration of multiple doses of 50 mg were as follows, t1/2: (6.1 +/- 1.7) h; AUC(ss): (10 071 +/- 4220) microg x h x L(-1); MRT: (8.1 +/- 2.3) h; and DF: (3.2 +/- 1.0).

OBJECTIVETo discuss the applied value of rescue intracytoplasmic sperm injection(ICSI) after complete fertilization failure during in vitro fertilization (IVF) cycles.

METHODSAfter 16-18 h co-culture with sperm, all the unfertilized oocytes with the first polar body were re-fertilized by ICSI.

RESULTSAfter rescue ICSI, the abnormal fertilization rate was 17.9% and the normal fertilization rate was 42.7%. Twenty-four hours later, the normal cleavage rate of the normal fertilized oocytes was 79.6%. On the day of embryo transfer, the good-quality rate of embryos was 29.7% (22/74). A mean number of 3.4 (54/16) embryos were transferred to the patient during each cycle. Clinical pregnancy was found in 3 cases out of the 16 (18.8%).

CONCLUSIONThe applied value of rescue ICSI may be correlated with the number and maturity of oocytes on the retrieval day.

Objective To evaluate the effect of health education in controlling the iodine deficiency diserders(IDD) in order to provide reference data for the further prevention and control. Methods Each village of 3 towns in Congjiang County was selected in 2007, where the health education lasting for 10 months had been implemented in the school students of 3-6 grade and the villagers. The school students of 3-6 grade and 30 housewives in the villagers were investigated for their IDD control knowledge, the salt consuming conditions as well as the sales of both rough and fine salt at a salt retail site in each village before and after the health education was implemented. Results The awareness rate of the knowledge of IDD control in the students and housewives was 91.4% (581/636) and 78.3% (282/360), respectively after intervention, which significantly increased (χ2= 532.044, 326.117, both P < 0.01) compared with the rate of 28.2% (184/652) and 11.4% (41/360) before intervention. The proportion of consuming fine salt was 91.8%(146/159) and 95.6%(86/90), significantly inereased(χ2= 236.623, 135.350, both P < 0.01) compared with 6.1%(10/163) and 7.8% (7/90) found before intervention. The selling proportion of fine salt at the salt retail site in the village was 60.0%(900/1500), significantly increased(χ2= 824.176, P < 0.01) compared with 10.0%(150/1500) before intervention. Conclusions Health education and promotion is solid foundation for effectively controlling IDD, through which the students and villagers are actively and voluntarily involved in the program and hence have formed good living and hygiene habits, thus expected effect has been obtained.
