Objective:To investigate the sleep quality of the people aged over 18-years-old in Hebei province and the impact of relative factors on it.Methods:Sum total of 20 716 random samples at ages over 18 were selected among the general population.The tools were Pittsburgh Sleep Quality Index(PSQI),Simplified Coping style Questionnaire(SCSQ).Results:The total prevalence of low sleep quality was 11.6 %(2411/20716).Female had higher standardized prevalence rate than male(6.8% vs.4.8%).Logistic analysis showed that risk factors to low sleep quality were ages over 70-years-old,remarriage,divorce,bereft,negative coping style(OR=1.776,1.515,2.046,1.254,1.097).On the other hand,factors to good sleep were the Han nationality,male,farmer,the family average annual income ranged 5001-10000 RMB,10001-20000 RMB,20001-40000 RMB,positive coping style(OR=0.839,0.703,0.732,0.750,0.660,0.573,0.936).Conclusion:Low sleep quality had high prevalence in Hebei.It should be recognized by medical workers.

Objective To evaluate the effects of ELISPOT (enzyme-link immunospot) test using different samples in diagnosing tuberculous pleurisy. Methods Using T-Spot-TB kit to detect interferon-γlevel in pleural effusion and periph?eral blood from 164 patients with tuberculous pleural effusion and 102 patients without tuberculous pleural effusion. Number of spot forming cells (SFCs) as well as the specificity and sensitivity of the tests were compared between these two methods (ELISPOT using leural effusion or peripheral blood). Results The area under the ROC curve was 0.947 in pleural effusion Elispot test while it was 0.905 in peripheral blood Elispot test. The sensitivity of pleural effusion ELISPOT test in diagnosis of tuberculous pleurisy (95.1%) was significantly higher than that of peripheral blood ELISPOT test (89.0%). What’s more, the specificity of pleural effusion ELISPOT test in diagnosis of tuberculous pleurisy (90.2%) was higher than that in diagno?sis of peripheral blood ELISPOT test (88.2%). Conclusion The pleural effusion ELISPOT test is more valuable than periph?eral blood ELISPOT in the diagnosis of tuberculous pleuritis.

Objective To investigate the clinical significance of serum pepsinogen (PG) in gastric cancer screening. Methods The clinical data of 930 patients underwent colonoscopy were retrospectively analyzed. Among them, non chronic atrophic gastritis was in 550 cases (chronic atrophic gastritis group), chronic atrophic gastritis in 300 cases (chronic atrophic gastritis group), gastric cancer in 80 cases (gastric cancer group). The patients in chronic atrophic gastritis group were divided into mild chronic atrophic gastritis subgroup (100 cases), moderate chronic atrophic gastritis subgroup (120 cases) and severe chronic atrophic gastritis subgroup (80 cases) according to the severity of the atrophy. The levels of serum PGⅠand PGⅡwere detected by enzyme linked immunosorbent assay (ELISA) method, and the ratio of PGⅠand PGⅡ(PGR) was calculated. Results There was no statistical difference in PGⅡ among the 3 groups (F = 1.226, P>0.05). The PG Ⅰand PGR in gastric cancer group were significantly lower than those in chronic atrophic gastritis and non chronic atrophic gastritis:(70.41 ± 39.42)μg/L vs. (83.10 ± 30.08) and (165.5 ± 41.40)μg/L, 3.76 ± 2.03 vs. 5.08 ± 1.82 and 6.84 ± 1.88, those in chronic atrophic gastritis were significantly lower than those in non chronic atrophic gastritis group, there were statistical differences (P<0.05). The PG Ⅰand PGR in mild and moderate chronic atrophic gastritis subgroup were significantly higher than those in severe chronic atrophic gastritis subgroup and gastric cancer group:(95.50 ± 30.80) and (82.10 ± 31.42)μg/L vs. (70.12 ± 20.12) and (70.41 ± 39.42) μg/L, 5.84 ± 2.88 and 5.08 ± 1.89 vs. 3.90 ± 2.78 and 3.76 ± 2.03, there were statistical differences (P<0.05), but there was no statistical difference between severe chronic atrophic gastritis subgroup and gastric cancer group (P>0.05), and there was no statistical difference between mild chronic atrophic gastritis subgroup and moderate chronic atrophic gastritis subgroup (P>0.05). The receiver operating characteristic (ROC) curve was used, the optimal critical value of PG Ⅰ was 74.8μg/L, the area under curve (AUC) was 0.842, the sensitivity was 90%, specificity was 75%;the optimal critical value of PGR was 4.46, AUC was 0.837, the sensitivity was 75%, specificity was 82%;the AUC of combined detection of PG Ⅰ and PGR was 0.906, the sensitivity was 88%, specificity was 85%. Conclusions Detection of PG Ⅰ combined with PGR can be used as gastric cancer screening, the recommended level of PGⅠ≤74.80μg/L and PGR≤4.46.

OBJECTIVE: To investigate the effect of eating on pharmacokinetics of ethanesulfonic acid levofloxacin tablets.METHODS: The blood concentration of 10 healthy male subjects were determined by HPLC after receiving single oral dose of 200mg ethanesulfonic acid levofloxacin both before and after eating by randomized crossover way.The data processing was conducted with 3p97 software so as to figure out the pharmacokinetic parameters.RESULTS: The plasma concentration-time curves of the subjects after administration of drugs were in conformity with two-compartment model.The respective main pharmacokinetic parameters of the eating group and the empty stomach group were as follows: Cmax were (1.91?0.36)mg/L and(2.16?0.69) mg/L; AUC0～t were (14.14?2.32)(mg?h)/L and(14.40?3.11)(mg?h)/L; t1/2? were(6.59?1.66)h and(6.94?0.81 )h.CONCLUSION: Neither eating nor empty stomach has effect on the pharmacokinetics of ethanesulfonic acid levofloxacin tablets.

Objective To assess the relationship between muscle strength , creatine kinase ( CK) and electromyography ( EMG) in patients with lipid storage myopathy ( LSM).Methods Motor and sensory nerve conduction study, F wave, and quantity EMG were performed in 30 patients with LSM.Muscle strength and CK were studied before EMG.The relationship between EMG , muscle strength and CK were analyzed.Results EMG showed myopathic changes in 19 patients,myopathic coexistence with neuropathic changes in five , and neuropathic changes in two.Four patients had normal EMG.Motor nerve conduction studies showed decreased compound muscle action potential amplitude in seven nerves of two patients , while abnormal sensory nerve conduction in 16 nerves of five patients.Quantity EMG was performed in 78 muscles.Thirty-eight muscles of 21 patients had decreased amplitude and short duration motor unit potential ( MUP) , 6 muscles of 2 patients had increased amplitude and long duration MUP , and 30 muscles of 16 patients had normal MUP.Abnormal spontaneous activities ( SA) were detected in 16 muscles.The M( Q25 , Q75 ) of serum CK was 295.5 (201.0, 4 845.8) U/L in patients with abnormal SA in EMG , and 482.0 (292.8, 963.8) U/L in patients without abnormal SA in EMG (Z=0.281, P=0.778).Medical Research Council ( MRC) Scale in deltoid muscle was 4.3 ±0.7 in muscles with SA and 4.1 ±0.8 in muscles without SA (t=0.490, P=0.628), and that in quadriceps femoris was 3.9 ±0.6 for muscles with SA and 3.7 ± 0.6 for muscles without SA ( t =0.725 , P =0.474 ).MRC Scale in deltoid muscle was 4.1 ±0.7 in muscles with myogenic MUP and 4.1 ±0.9 in muscles without myogenic MUP ( t=0.101, P=0.920), which in quadriceps femoris was 3.8 ±0.6 for muscles with myogenic MUP and 3.7 ±0.7 for muscles without myogenic MUP ( t=0.368 , P=0.716 ).Conclusions Neurogenic or normal MUP and abnormal sensory nerve conduction can be presented in some patients with LSM , while SA is not common.The changes in MUP and SA are neither correlated with CK nor with muscle strength.

Objective To investigate the diagnostic values of procalcitonin (PCT),high sensitive C-reactive protein (hs-CRP),white blood cell (WBC)and percentage of neutrocyte (NEU％)in Gramnegative and Gram-positive bacterial blood stream infection in early stage of sepsis in order to investigate the correlation between PCT and APACHE lⅡ score as well as between PCT and SOFA score,and the prognostic value in assessment of Gram-negative and Gram-positive bacterial blood stream infection.Methods Clinical data of patients admitted to ICU from January 2012 through December 2014 were retrospectively analyzed.A total of 124 sepsis patients with blood stream infection were checked with PCT,hs-CRP,WBC and NEU％ tests,and APACHE Ⅱ score and SOFA score were calculated.The differences in APACHE Ⅱ score and SOFA score were compared between Gram-negative group (n =41) and Gram-positive group (n =83).The correlation between PCT and APACHE Ⅱ score as well as between PCT and SOFA score was analyzed.The differences in diagnostic values of PCT,hs-CRP,WBC and NEU％ between Gram-negative group and Grampositive group were analyzed by using receiver operating characteristic (ROC) curve and it was plotted to assess the prognostic values of PCT,hs-CRP,WBC and NEU％ for septic patients with blood stream infection.Results Compared with Gram-positive group,the levels of PCT [.55.32 (22.01,97.11) vs.2.13 (0.27,5.27)] (P ＜0.01),hs-CRP [105.09 (69.97,186.12) vs.70.54 (42.37,138.63)] (P=0.508),NEU％ [88.30 (75.79,93.52) vs.55.32 (22.01,97.11)] (P=0.302) were higher but WBC was lower [13.59 (10.74,17.58) vs.13.73 (11.32,20.90)] (P=0.058) in Gram-negative group.The ROC curve analysis of PCT showed the area under the curve (AUC) was 0.867 (95％ CI:0.789-0.946).When the optimal cutoff point of PCT was 17.48 ng/mL,the largest Youden's index was found to be 0.661 with 76.9％ sensitivity and 89.2％ specificity.Between two groups,there were significant differences in APACHE Ⅱ score and SOFA score (27.46 ± 9.60 vs.23.67 ± 7.74,P =0.020;8.05 ±3.38 vs.6.59-±3.45,P =0.028).There was significant difference in diagnostic value between PCT and SOFA (r =0.536,P =0.036) in Gram-negative group but no significant difference in Gram-positive group.Conclusions Higher PCT levels are found in Gram-negative group and it can play a role in differntiation between the Gram-negative group and Gram-positive group rather than hs-CRP,WBC and NEU％.PCT can be a better indicator for evaluation of severity of sepsis as well as for prognosis of sepsis patients with Gram-negative bacterium infection.

Objective To study the cytogenetic features of acute myeloid leukemia (AML) and analyze the association with cytogenetic features and early responses after induction therapy.Methods The karyotypes of 395 patients who had been newly diagnosed with AML were analyzed.These patients were divided into three groups (low-risk,intermediate-risk and high-risk),according to the AML NCCN guidelines.The incidence of different karyotypes in these three groups and the complete remission (CR) rate after the first cycle of induction therapy were analyzed.Results The incidence rates of karyotypes in high-risk,intermediate-risk and low-risk groups were 50.56 ％ (180/356),39.89 ％ (142/356),9.55 ％ (34/356),respectively.All patients with t(15;17) who completed induction therapy reached CR.There was significant difference in the CR rates of t(8;21) groups with or without additional karyotypes [92.00 ％(23/25) vs 50.00 ％(11/22)] (x2 =10.317,P =0.001).There was no significant difference in the CR rates between normal and-Y karyotype group [61.90 ％ (39/63) vs 58.82 ％ (10/17)] (x2 =0.054,P =0.817).Complex cytogenetics ascribed to the low-risk group,of which monosomal karyotype was common,nine of ten patients with monosomal karyotype were associated with an inferior CR rate.Conclusion The cytogenetic features of AML are different from previous reports by other centers.The cytogenetic features of AML patients not only influence the long-term survival,but also the CR rates of induction therapy.

Objective To investigate the changes of cardiac function at pre -and post -treatment in preterm infants with patent ductus arteriosus (PDA)in order to guide drug treatment.Methods Totally 84 preterm infants with PDA admitted to Neonatal Intensive Care Unit of Xuzhou Hospital Affiliated to Medical College of Southeast University from July 201 2 to June 201 4 were divided into 4 groups according to treatment drug:Ibuprofen group (27 cases),Indo-methacin group (24 cases),control group (1 1 cases),and Paracetamol group (22 cases).Patients were also divided into symptomatic PDA group (38 cases)and asymptomatic PDA group (46 cases)according to severity;PDA closed group (69 cases)and PDA unclosed group (1 5 cases)according to sequel.The level of plasma brain natriuretic pep-tide (BNP),cardiac troponin I (cTnI),correct QT intervals dispersion (QTcd)were monitored pre -and post -treat-ment.Data were analyzed by using SPSS 1 9.0 software.Results Three cardiac markers at post -treatment were of no significant difference among 4 treatment drugs.The changes of the cTnI and QTcd at pre -and post -treatment were of no significance.The level of BNP in symptomatic PDA group was significantly higher than that in asymptomatic PDA group at pre -treatment [(378 ±94)ng/L vs (1 47 ±75)ng/L,t =2.584,P =0.01 4].In the symptomatic PDA group,the level of BNP at post -treatment [(1 82 ±81 )ng/L]was significantly decreased than that at per -treatment (t =2.741 ,P =0.009).In the asymptomatic PDA group,there was no significant difference between the pre - and post -treatment [(1 21 ±61 )ng/L]in the level of BNP (t =1 .254,P =0.207).There was no significant difference in the level of BNP at per -treatment between PDA closed group and PDA unclosed group [(274 ±91 )ng/L vs (289 ± 87)ng/L,t =-0.874,P =0.391 ].In PDA closed group,the level of BNP at post -treatment [(1 21 ±74)ng/L] was significantly decreased compared with that at per -treatment (t =3.580,P =0.000).In PDA unclosed group, there was no significant difference between the pre - and post -treatment [(245 ±74)ng/L]in the level of BNP (t =0.854,P =0.392).Conclusion Early medication intervention for symptomatic PDA of preterm infants is benefi-cial for the closure of PDA and for attenuating negative effects on cardiac function of PDA.
