Objective To evaluate the efficiency of the application of array comparative genomic hybridization (array-CGH) in preimplantation genetic diagnosis or screening (PGD/PGS), and compare the clinical outcomes of different stage embryo biopsy. Methods The outcomes of 381 PGD/PGS cycles referred in the First Affiliated Hospital of Nanjing Medical University from July 2011 to August 2015 were retrospectively analyzed. There were 320 PGD cycles with 156 cleavage-stage-biopsy cycles and 164 trophectoderm-biopsy cycles, 61 PGS cycles with 23 cleavage-stage-biopsy cycles and 38 trophectoderm-biopsy cycles.Chromosomal analysis was performed by array-CGH technology combined with whole genome amplification.Single embryo transfer was performed in all transfer cycles.Live birth rate was calculated as the main clinical outcomes. Results The embryo diagnosis rate of PGD/PGS by array-CGH were 96.9%-99.1%. In PGD biopsy cycles, the live birth rate per embryo transfer cycle and live birth rate per embryo biopsy cycle were 50.0%(58/116) and 37.2%(58/156) in cleavage-stage-biopsy group, 67.5%(85/126) and 51.8%(85/164) in trophectoderm-biopsy group (both P<0.01). In PGS biopsy cycles, the live birth rate per embryo transfer cycle and live birth rate per embryo biopsy cycle were the same as 34.8%(8/23) in cleavage-stage-biopsy group, the same as 42.1%(16/38) in trophectoderm-biopsy group (both P>0.05). Conclusions High diagnosis rate and idea live birth rate are achieved in PGD/PGS cycles based on array-CGH technology.The live birth rate of trophectoderm-biopsy group is significantly higher than that of cleavage-stage-biopsy group in PGD cycles;the efficiency of trophectoderm-biopsy is better.

Objective To explore the clinical significance of procalcitonin(PCT) in the diagnosis of bacterial infection in burn pa‐tients .Methods Among 169 burn patients ,96 cases were bacterial infection confirmed by blood ,secretion and puncture fluid culture and 73 cases were non‐bacterial infection .PCT ,WBC and hyper sensitive C reactive protein (hs‐CRP) were detected .The diagnostic values in bacterial infection were compared among these 3 indexes and the relationship between PCT level and burn degree was fur‐ther studied .Results Serum PCT ,WBC and hs‐CRP levels in the bacteria infection group were obviously higher than those in the non‐bacterial infection group(P<0 .05);the sensitivity ,specificity ,positive predictive value and negative predictive value of PCT were 90 .63% ,89 .04% ,91 .58% and 87 .84% respectively ,which indicated that PCT had higher diagnostic value than WBC and hs‐CRP .The PCT level was positively correlated with the degree of burn degree .Conclusion Serum PCT ,WBC and hs‐CRP in the burn patients with bacteria infection are greatly increased .PCT as the marker of bacterial infection has the higher sensitivity and specificity than WBC and hs‐CRP in the diagnosis of bacteria infection .

Objective Kidney-supplementing and blood-activating method was adopted in treating senile patients with isolated systolic hypertension to observe its decompression effects and influences on microalbunminuria (Malb),retinol binding protein (RBP) level in 24 hours.Methods 90 patients with simple systolic hypertension were randomly recurited into two groups.52 cases in the treatment group were administered with kidney-supplementing and blood-activating decoction,including 1 case falling off and 51 cases entering statistical analysis; 38 cases in the control group were administered with oral placebo,among them 2 cases were fallen offand 36 cases were entered statistical analysis.Both groups were treated for 8 weeks.Results () Blood pressure:systolic blood pressure at 4 and 8 weeks after the treatment in the treatment group [(144.03±12.33)mmHg (1 mmHg=0.133kPa) and (132.27±13.15)mmHg] wassignificantlyimproved than before the treatment [(156.32±12.05)mm Hg] (P＜0.05),and also significantly better than the control group at 4,8 weeks after the treatment [(151.19± 13.83)mm Hg,(152.74± 12.03)mm Hg] (P＜0.05).②The Malb,RBP level:Malb,RBP level [(40.80±13.51)mg/L,(150.43±23.62)mg/L] after the treatment in the treatment group was reduced than before the treatment [(50.14± 15.61)mg/L,(220.04±30.20) mg/L] (P＜0.05),and was significantly different to the control group after treatment [(52.12±14.69)mg/L,(219.34±34.37)mg/L] (P＜0.05).Conclusion Kidney-supplementing and blood-activating method can improve kidney function,and thus to reduce the effect of systolic blood pressure.

Objective To evaluate the efficacy and safety of continuous erythropoietin receptor activator (C.E.R.A.) once every 4 weeks by subcutaneous administration on hemoglobin (Hb)maintenance in dialytic patients with chronic renal anemia who had been treated with stable dose of erythropoietin (EPO).Methods This was an open,randomized,controlled,multi-center trial.All the hemodialysis or peritoneal dialytic patients in EPO maintenance treatment received subcutaneous EPO-β during the 6-week pre-treatment period to maintain Hb level between 100 g/L and 120 g/L.Eligible patients were randomized (2∶1 ) to accept either C.E.R.A.once every 4 weeks by subcutaneous administration ( C.E.R.A.group,n =187 ) or subcutaneous EPO-β 1-3 times weekly ( EPO group,n =94) for 28 weeks (including 20-week dose titration period and 8-week efficacy evaluation period ). The starting dose of C.E.R.A.was converted according to the dose of EPO-β administered in the week preceding the first study drug administration.The primary outcome was the change of Hb level between the baseline and that in the efficacy evaluation period.Results Totally 253 patients completed the whole 28-week treatment.The change of baseline-adjusted mean Hb was +2.57 g/L for C.E.R.A.group and + 1.23 g/L for EPO group,resulting in a treatment difference of 1.34 g/L (95％ CI - 1.11-3.78 g/L).Since the lower limit of 95％ CI was greater than the pre-defined non-inferiority margin -7.5 g/L( P ＜ 0.0001 ),C.E.R.A.once every 4 weeks by subcutaneous administration was clinically non-inferior to EPO regarding the maintenance of stable Hb level.The proportion of patients maintaining Hb level within the range of 100-120 g/L through efficacy evaluation period was similar between the two groups ( 69.0％ for C.E.R.A.group vs 68.9％ for EPO group,P ＞0.05 ).The overall incidence of adverse events was similar between the C.E.R.A.(41.7％)and EPO (46.2％ ) groups ( P ＞ 0.05 ).The safety findings were in accordance with the patients' primary diseases rather than the administration.Conclusions Conversion from EPO to C.E.R.A.once every 4 weeks by subcutaneous injection could maintain the Hb in target level in dialytic patients with renal anemia,and it was non-inferior to EPO.In general,subcutaneous administration of C.E.R.A.is well tolerated in dialytic patients with chronic renal anemia.

Objective: To establish a quantitative model for evaluating the degree of traditional Chinese medicine (TCM) syndromes often seen in patients with coronary heart disease (CHD). Methods: Medical literature concerning clinical investigation of TCM syndromes of CHD was collected and organized, and the "Hall for Workshop of Metasynthetic Engineering" expert symposium method was applied. First, the 100 millimeter scaling was used for combining with scoring on degree of symptoms to establish a quantitative criterion for classification of symptom degree in CHD patients, and the model was established by using comprehensive analytic hierarchy process as the mathematical tool to estimate the weight of the criterion for evaluating qualitative syndromes in various layers by specialists. Then the model was verified in clinical practice and the outcomes were compared with fuzzy evaluation from the specialists. Results: A total of 287 clinical observation forms on CHD cases were collected, and 167 forms were available after excluding any irregular forms. The results showed that basic coincidence rate between the outcomes derived from specialists and those from the model was 68.26% (114/167), and part coincidence rate was 88.62%(148/167). Conclusion: This model, with good rationality and feasibility, has a high coincidence rate with fuzzy evaluation from specialists, and can be promoted in clinical practice. It is a good quantitative model for evaluating the degree of TCM syndromes of CHD.

Objective To investigate the relationship between serum progesterone level at the day with human chorionic gonadotrophin (hCG) administration and pregnant outcome from in in-vitro fertilization-embryo transfer(IVF-ET). Methods From Mar. 2002 to Apr. 2007, 786 cycles with serum progesterone measurement on the day of hCG administration for final oocyte maturation in IVF were analyzed retrospectively in Reproductive Medicine Center in First Affiliated Hospital of Nanjing Medical University.All stimulations were down-regulated with gronadotrophin release hormone agonist (GnRH-a) in both long protocols and short protocols before gonadotrophin stimulation. When the thresholds of serum progesterone were set at 5.5, 6.0,6.5,7.0,7.5,8.0,8.5 and 9.0 nmol/L, respectively. If the level of progesterone was less than the thresholds, those patients were in lower progesterone group, on the contrary, more than the threshold value, those patients were in higher progesterone group. The laboratory results and the clinical outcomes between all patients at lower and higher progesterone group at different thresholds value were analyzed. Results The rate of normal fertilization, quality embryos, successful implantation, chemical pregnancy, clinical pregnancy and live birth did not exhibit remarkable difference between patients with higher and lower serum progesterone level at multiple thresholds on the day of hCG administration in the 786 cycles (P >0.05). However, when the thresholds of serum progesterone were at 8.5 and 9.0 nmol/L, early abortion rates of 27.3% (3/11) and 3/7 in higher progesterone group were significantly higher than 8.8% (26/297) and 8.6% (26/301) in lower progesterone group (P<0.05). And the total abortion rates of 3/7 in higher progesterone group were significantly higher than 11.0% (34/301) in lower progesterone group when the thresholds of serum progesterone were 9.0 nmol/L (P<0.05). Conclusions This study did not prove the correlationship between progesterone level at the clay with hCG administration and the probability of clinical pregnancy or live birth. However, early abortion rates or the total abortion rates were associated with higher progesterone level when the thresholds of serum progesterone were at 8.5 nmol/L or 9.0 nmoL/L.
