Chinese Journal of Primary Medicine and Pharmacy 2011;18(6):780-781
Objective To evaluate the clinical management and outcome in pregnancy complicated with preterm premature rupture of membranes (PPROM). Methods The clinical data of 98 patients with PPROM were retrospectively analyzed. 20 patients with PPROM at 28 ~ 33 +6 weeks were selected as the early group, while 78 patients with PPROM at 34 ~ 36 +6 weeks as the late group. Results The puerperal infection, postpartum hemorrhage and delivery methods had no statistical differences between early group and late group (all P>0. 05). The neonatal Apgar Score in early group was less than that in late group ( all P < 0. 05). The incidences of neonatal respiratory distress syndrome,infection and death in early group were higher than that in late group. There were significant differences between two groups (all P < 0.05). Conclusion Pregnancy between 28 and 34 weeks gestation with PPROM should be managed expectantly to protect fetus to 34 weeks and over. Pregnancy should be terminated appropriately by use of suitable delivery method. The above methods could effectively decrease occurrence incidences of complications and mortality.

Clinical Medicine of China 2016;32(6):521-526
Objective To analyze serum calcium and phosphorus levels and its related factors of clinical type 2 diabetes mellitus (T2DM) with overt diabetic kidney disease (T2-dDKD).Methods Ninety cases of T2DM patients according to K/DOQI Recommendations in 2007 were selected as the study subjects.Based on the patients' 2 times mean urinary albumin/creatinine ratio (ACR),these people were divided into three groups,namely Normal albuminuria group (30 patients,ACR<30 mg/gCr),Microalbuminuria group (30 patients,ACr =30-300 mg/gCr),Macroalbuminuria group (30 patients,ACR>300 mg/gCr).Thirty cases of healthy at the same period were selected as the Control group.Serum calcium,phosphorus,hs-CRP,IL-6,HbA1c were detected.And glomerular filtration rate (eGFR) was calculated.Results The eGFR in Normal albuminuria group was more higher than other groups (P<0.05),the eGFR of Microalbuminuria group was significantly lower than other groups (P<0.05).Subgroups of T2DM with different albuminuria presence and severity,duration was also different between the groups,the more albumin in urine,the longer its duration.The contents of HbA1c in the groups of varying degrees of albuminuria increased as urinary albumin aggravation (HbA1c was (8.87±2.44) %,(9.27±2.74)%,(11.04±2.86)% respectively,P<0.05),but there was not statistically significant between Microalbuminuria group ((9.27±2.74)%) and Normal albuminuria group ((8.87±2.44) %).Compared with Control group,in subgroups of T2DM,serum calcium was decreased((2.22±0.19) mmol/L,(2.16±0.14) mmol/L,(2.13±0.18) mmol/L,and the Contorl group was (2.32±0.11)mmol/L,P<0.05),and serum phosphorus ((1.16±0.31) mmol/L,(1.42±0.52) mmol/L,(1.98±0.58)mmol/L,and the Control group was (1.08±0.28) mmol/L),hs-CRP ((4.82±0.89) mmol/L,(8.46± 2.85)mmol/L,(13.09±3.49) mmol/L,and the Control group was (2.46±0.48) mmol/L),IL-6((10.32±4.19)pg/L,(14.78±4.34) pg/L,(16.67±6.62) pg/L,and the Control group was (7.03±2.15) pg/L) were increased(P<0.05).In subgroups of T2DM,hs-CRP was significantly increased with the increase of the serum albumin((4.82±0.89) mmol/L,(8.46±2.85) mmol/L,(13.09±3.49) mmol/L,P<0.05),there were no statistical significance about blood phosphorus among Macroalbuminuria group (1.98±0.58) mmol/L),control group((1.08±0.28) mmol/L),normal albuminuria group((1.16±0.31) mmol/L) and albumin urinary group (1.42±0.52) mmol/L).Serum phosphorus in Microalbuminuria group were positively correlated with hs-CRP,IL-6,HbA1c (r =0.431,0.384,0.517 respectively,P<0.05).Serum phosphorus in Macroalbuminuria group were positively correlated with hs-CRP,IL-6,HbA1c (r=0.825,0.622,0.683 respectively,P<0.01),but negatively with eGFR(r=0.600,P<0.01).Conclusion Serum phosphorus metabolism is abnormal in patients with diabetic nephropathy,hs-CRP,IL-6,and HbA1c are the related factors influencing the progression of serum phosphorus in patients with diabetic nephropathy.

4.Analysis on positive confirmation result of HIV antibody prelimicnary screening in voluntary blood donation
International Journal of Laboratory Medicine 2016;37(15):2112-2114
Objective To analyze the screening and confirmation test results of human immunodeficiency virus (HIV) antibody during 2009-2015 to provide the basis for the recruiting strategies in recruiting blood donors among the low risk population and blood donor′s returning to the team .Methods The blood samples of voluntary blood donors were detected the HIV antibody by the ELISA method ,with the reagents provided by 2 different manufacturers .The samples of HIV antibody positive or suspected sam‐ples were submitted to the Shenzhen Municipal Center for Disease Control and Prevention CDC for conducting the Western blot confirmation .The confirmation results of blood samples during 2009 -2015 were statistically analyzed .Results There were 197 766 blood samples from 2009 to 2015 .The overall infection rates of HIV were 1 .3 ,4 .7 ,5 .6 ,5 .4 ,5 .3 ,4 .6 ,7 .3/one hundred thousand respectively ,the average infection rate was 0 .004 9% (4 .9/one hundred thousand) ,the average confirmed positive rate was 22 .1% ,the false positive rate was 77 .9% .Among the blood donors of confirmed positive HIV antibody ,the donors aged 18-30 years old accounted for 67 .7% .Conclusion It is important for the recruitment work before the blood donation .Aiming at the blood donors of workers from outside and relative low cultural level ,especially the blood donors of high risk behavior ,the small card mode could be adopted to guide them to the disease control center to conduct the professional consultation and detection ,which can increase the blood transfusion safety coefficient and also prevents the spread of HIV/AIDS .Aiming at the false positive blood do‐nors ,the works of follow up ,tracking monitoring and return to the blood donation team should be done well for reducing the run a‐way of blood donors .Selecting more sensitive reagents and more sensitive method for the amplification of virus nucleic acid can shorten the infection risk of the window period as far as possible for ensuring the safety of blood transfusion .

0.05).(4) There was significant correlation between CD62p and CD63 ( P 0.05). Conclusions Patients with cerebral infarction show evidence of enhanced platelet activation and increasment of MPV and MAR,which may relate to the pathological process of cerebral infarction. Moreover MPV and MAR can reflect the clinical severity of cerebral infarction better than PLT. Anti-platelet aggregation treatment should be further taken in patients with cerebral infarction.

Objective To detect the relationship between XPD Lys751Gln polymorphism and the risk of adult acute leukemia (AL). Methods 100 adult AL patients and 100 controls were chose as case and Lys751Gln were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCRRFLP) analysis in peripheral blood. Results The genotype frequency of Lys/Lys, Lys/Gln, Gln/Gln were 83 %, 16 %, 1% in case group and 90 %, 10 %, 0 in control group, respectively. The difference the two groups was no signficant difference (x2=1.44, P =0.49). No significantly increased risk for adult AL was observed for those carrying variant genotype with OR analysis (x2 = 2.10, P =0.15, OR =1.84; 95 % CI 0.80-4.25). Individuals with the variant genotype of XPD Lys751Gln might enhance the risk of adult AL (OR =2.77, 95 % CI 0.99-7.73). Conclusion XPD Lys751Gln polymorphism is found to have relationship with adult acute lymphocytic leukemia.

Currently, histological and molecular methods are considered for the treatment of advanced non-small cell lung cancer (NSCLC). Single-agent epidermal growth factor receptor tyrosine-kinase inhibitors (EGFR-TKIs) and anaplastic lymphoma kinase in-hibitors (ALK-TKIs) have been used as standard first-line therapies for patients with active EGFR mutation and ALK rearrangement, re-spectively. However, to date, the single-agent EGFR-TKIs as the first-line therapy for patients with known EGFR mutations has been demonstrated to provide a prolonged progression-free survival but does not affect overall survival (OS). Physicians these days focus on improving the OS of patients with advanced NSCLC. To patients with EGFR mutation, combining and maintaining EGFR-TKIs with chemotherapy could be a promising approach. In this article, various ways of combining EGFR-TKIs with chemotherapy were explored.
