Objective To evaluate the clinical significance of the combined determination of serum procalcitonin (PCT),C reactive protein(CRP),prealbumin(PA)and white blood cell(WBC) in curative effect and prognosis of elderly patients with bacterial infection.Methods Serum PCT,CRP,PA and WBC levels and their dynamic changes of 70 patients with bacterial infection from intensive care unit(ICU)were measured.The patients with bacterial infection were classified into serious infection group and local infection group.And the comparison with virus infection group was made.Results The levels of PCT(18.00±3.20)μg/L and CRP(86.17±10.64)mg/L in serious infection group and local infection group[PCT(2.03±0.46)μg/L,CRP(50.24±7.45)mg/L] were increased.The contents of PA were reduced[(3.214±0.88)mg/L,(12.89± 1.03)mg/L].The levels of WBC were increased mildly[(8.89±1.23) × 109/L,(6.54±0.87) × 109/L].The differences were statistically significant between bacterial infection groups(serious infection group and local infection group) and virus infection group [PCT (0.21 ±0.06)μg/L,CRP (5.21 ±0.84) mg/L,PA (20.14 ±2.57)mg/L,WBC (5.30 ± 0.93) × 109/L] (P＜ 0.01).Serum PCT,CRP.PA and WBC showed significant differences between serious infection group and local infection group(P＜0.01).After antibiotic treatment,the levels of PCT (0.5 ± 0.08) μg/L,CRP (10.32 ± 1.65) mg/L and WBC (6.30± 0.91) × 109/L in bacterial infection group were reduced obviously and the concentration of PA (18.19±2.66)mg/L was elevated compared with before treatment [PCT(11.61±8.27)μg/L,CRP (71.80±20.09)mg/L,WBC(7.95± 1.59) × 109/L,PA(7.08±4.87)mg/L] (P＜0.01).Correlative analysis was performed between PCT and others indicators before and after antibiotic treatment in bacterial infection group and virus infection group.There was positive correlation between PCT and CRP,WBC before(r=0.586,0.445) and after treatment (r=0.688,0.463) in bacterial infection group.PCT and WBC(r=0.432) were positively correlated after treatment,while no correlation existed between PCT and others indexes in virus infection group(r＜0.306).When comparing sensitivity and specificity of PCT and CRP for diagnosis of bacterial infection disease,the sensitivity (95.7％) of PCT was similar to that of CRP.The specificity of PCT(86.7％) was remarkably higher than that of CRP(73.3％).Conclusions The combination of serum PCT,CRP.PA and WBC is valuable for early diagnosis of bacterial infection disease.Monitoring PCT level dynamically would assist an evaluation of curative effect and disease outcome of elderly patients.

Objective To investigate the effects of whole grain-bean mixed staple food on intestinal microecology,anthropometric,and metabolic parameters of obese people.Methods Totally 87 obese people were divided with random number table into whole grain-bean mixed staple food group (test group) and refined grains staple food group (control group).Body weight (BW),body mass index (BMI),waist circumference (WC),hip circumference (HC),waist/hip ratio (WHR),fasting plasma glucose (FPG),triglyceride (TG),total cholesterol (TC),high-density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol (LDL-C),and colony count of intestinal flora (bacillus bifidus,lactobacillus,clostridium perfringens,enterobacteria,enterococcus,bacteroides) were measured at baseline and 3 months after intervention.Results Ten people were excluded from this research,6 in the test group and 4 in the control group.Mter 3 months of dietary intervention,BW,BMI,WC,HC,and WHR were significantly lower in the test group than in the control group [(69.45 ± 7.07) kgvs.(72.42 ±5.79) kg,P=0.000; (26.08 ±1.48) kg/m2 vs.(27.27 ±0.81) kg/m2,P=0.000; (82.48±9.30) cm vs.(86.96±4.93) cm,P =0.000; (90.08 ±6.57) cm vs.(92.42 ±6.67) cm,P =0.000; 0.92 ±0.11vs.0.95 ±0.10,P =0.003].The levels of FPG,TC,and LDL-C in the test group were significantly lower than those in the control group [(4.92 ± 0.75) mmoL/L vs.(5.41 ± 1.21) mmoL/L,P=0.037; (3.85±1.13) mmoL/L vs.(4.38 ±1.26) mmoL/L,P=0.046; (3.55 ±1.04) mmoL/L vs.(4.16 ± 1.40) rnmoL/L,P =0.033] ; the level of HDL-C in the test group was significantly higher than that in the control group [(1.13 ± 0.37) mmoL/L vs.(0.92 ± 0.26) mmoL/L,P =0.004].The colony counts of intestinal bacillus bifidus,lactobacillus,and bacteroides in the test group were significantly higher than in the control group [(7.94 ± 0.58) lg CFU/g vs.(6.95 ± 0.38) lg CFU/g,P =0.000 ; (7.67 ± 0.46) lg CFU/g vs.(6.96 ± 0.57) lg CFU/g,P =0.000 ; (5.53 ± 0.44) lg CFU/g vs.(4.80 ±0.23) lg CFU/g,P =0.000],while the colony count of clostridium perfringens was significantly lower than in the control group [(4.40 ± 0.49) lg CFU/g vs.(5.11 ± 0.63) lg CFU/g,P =0.000].Conclusions In obese people,whole grain-bean mixed staple food can improve anthropometric parameters,some lipid metabolic parameters,and intestinal flora.The underlying mechanism may involve promoting the survival and proliferation of probiotics,thereby improving glucose and lipid metabolism.

Objective To explore the level of free fatty acid (FFA)in ischemic stroke (IS) patients and its correlation with insulin resistance (IR).Methods This study was case-control study.Patients who were diagnosed with IS were followed up from June,2011 to September,2012 in Tianjin Third Central Hospital.The 180 IS patients were divided into large infarct(57),middle infarct(63)and small infarct (60) according to the area of infarct.At the same time,60 healthy persons were selected as control group.The plasma FFA,fasting insulin (FINS),fasting blood glucose (FBG),homeostasis model assessment (HOMA)-IR,triacylglycerol (TG),total cholesterol (TC),high density lipoprotein cholesterol-C (HDL),low density lipoprotein cholesterol-C(LDL),lipoprotein A1 (APOA1) and lipoprotein B (APOB) in 180 IS patients were measured and compared with that of control group.The correlation between FFA and IR was analyzed by using pearson linear correlation.The relationship between FFA and HOMA-IR was analyzed by using multiple stepwise multivariate analysis.The t test and analysis of variance were used for statistical analysis.Results Compared to normal control,the level of FFA,FINS,FBG,FIB,TG,TC,LDL,APOB and HOMA-IR in IS patients were higher,the difference was statistically.The level of HDL,APOA1 in IS patients were lower than that of normal control.The level of FFA,FINS,HOMA-IR,FBG,TG,TC,HDL,LDL,APOA1 and APOB in IS patients related to the area of infarct.The level of FFA,FINS,HOMA-IR,FBG,TG,TC,LDL,APOB in large infarct were higher than those in middle infarct and small infarct.The level of HDL,APOA1 in large infarct were lower than those in middle infarct and small infarct,the difference were statistically.In IS patients,FFA had positive correlation to FINS,FBG and HOMA-IR (r =0.870,0.497,0.792,P ＜ 0.001),but had no correlation to age (r =0.008,P ＞ 0.05).In IS patients,HOMA-IR was dependent variable,but FFA,FINS,FBG,TG,TC,HDL,APOA1 and APOB were independent variable.FFA was independent risk factor to HOMA-IR,besides FINS,FBG,TC,LDL and APOB.Conclusion FFA elevates in IS patients,FFA has correlation to IR and it is a dependent risk factor to IS patients.

The aim of this study is to investigate the critical factor affecting the properties of PLGA microspheres fabricated by a solid-in-oil-in-water (S/O/W) emulsion technique with BSA as a model protein. Prior to encapsulation, the BSA microparticles were fabricated by a modified freezing-induced phase separation method. The microparticles were subsequently encapsulated into PLGA microspheres by S/O/W emulsion method, then Motic BA200 biological microscope, confocal laser scanning microscope, scanning electron microscope were used to observe the structure of S/O/W emulsion and PLGA microspheres. The protein content extracted or released from BSA microspheres was measured by Bradford protein assay method. It was found that NaCl added in the outer aqueous phase effectively suppressed material exchange between the inner and outer phase of S/O/W emulsion. Then, the structure and permeability of obtained microspheres were influenced. As a result, with the increase of NaCl concentration in the outer aqueous phase, the encapsulation efficiency of microspheres significantly increased from 60% to more than 85%, the burst release of microspheres reduced from 70% to 20%, and the particle size decreased from 103 microm to 62 microm. Furthermore, the rehydration of encapsulated protein was also retarded and then integrity of BSA was successfully protected during encapsulation process. In vitro release test showed that BSA released from PLGA microspheres in a sustained manner for more than 30 days.

Objective To investigate the effect of Roy Adaptation Model(RAM)in patients with adolescent insanity.Methods One hundred patients with adolescent insanity during October 2011 to March 2012 were randomized in equal number into two groups by random digit table:the study group and the control group.The former were intervened with RAM and the latter received routine care and health education.Seven weeks after intervention,Hamilton Depression Rating Scale(HAMD),Hamilton Anxiety Scale(HAMA) and Observation Scale(NOSIE)were used for the assessment. Results After intervention,the scores on HAMD and HAMA in the study group were significantly lower,compared to the control group(P<0.01).The scores on social function,social interest,subjective support and use of social support were all significantly higher than those of the control group(all P<0.01). Conclusions RAM can improve their ability of the patients with adolescent insanity to adapt to the environment.It may improve their mental state and their quality of life.

OBJECTIVE: To explore the curative effect of nasal type extranodal NK/T-cell lymphoma by sequential chemotherapy combined radiotherapy compared with chemtherapy. METHOD: Fifty-seven cases of nasal type extranodal NK/T-cell lymphoma confirmed by pathological morphology and immuno-histochemistry were divided into chemotherapy combined radiotherapy group (34 cases) or chemotherapy group (23 cases). Twenty-three patients in the chemotherapy group alternately applied CHOP, VDLP and MEOP regimen after each two treatments into the clinical observation; Chemotherapy combined radiotherapy group of 34 patients, in addition to the above chemotherapy, applied three-dimensional conformal radiation therapy of the primary site by linear accelerators. Then all of patients were ceased treatment and followed up 3-5 years. RESULT: (1) After treatment, effective rate of two groups was 91.2% and 87.0%, there was no obvious difference (P > 0.05); After follow up about 1 year, effective rate of two groups was 76.5% and 73.9%, there was no obvious difference (P > 0.05); (3) After follow up about 3 years and 5 years, disease free survival (DFS) of two groups was 61.3%, 47.6% and 43.5%, 21.4%, there was obvious difference (P < 0.05). (4) Long-term survival is closely related to treatment mode. (5) B symptoms, advanced (III, IV) stage, the International Prognostic Index (IPI), KPS scores were correlated with prognosis, and were independent prognostic factors. CONCLUSION Treatment with chemotherapy and radiotherapy for nasal type extranodal NK/T-cell lymphoma had obvious curative effect and may improve long-term survival efficiently compared with chemotherapy alone.

Objective To evaluate the efficacy and safety of focal fractional laser treatment(FFLT)for atrophic acne scars. Methods A randomized, self-controlled study was performed. A total of 20 patients with atrophic facial acne scars were enrolled into this study. Treatments were randomly administered in a split-face manner. Half of each subject′s face received FFLT(FFLT side), and the other half underwent full-face fractional CO2 laser resurfacing(control side), for one session. All the patients were followed up for 3 months after the treatment. Evaluation was based on the ECCA grading scale (échelle d′évaluation clinique des cicatrices d′acné)and patient satisfaction score. A VISIA skin detector was used to take photographs and evaluate skin texture. Moreover, physical parameters of the skin, including erythema index, melanin index and transepidermal water loss (TEWL), were measured. Adverse effects were recorded and evaluated. Statistical analysis was carried out by paired t test, Wilcoxon paired rank test, Fisher′s exact test and repeated-measure analysis of variance. Results The ECCA score decreased from 51.24 ± 17.61 at the baseline to 34.46 ± 14.99 at 3 months after the treatment at the FFLT side(t = 7.886, P < 0.05), and from 50.96 ± 18.96 to 38.29 ± 14.86 at the control side(t =6.123, P < 0.05), and was significantly lower in the FFLT side than in the control side (t = 4.462, P < 0.05)at 3 months after the treatment. The improvement rate was significantly higher in the FFLT side than in the control side (32.75% vs. 24.86%, P = 0.016 by Fisher′s exact test)at 3 months after the treatment. Decreased pain and edema scores were observed at the FFLT side compared with the control side at 1 hour after the treatment (both P < 0.05), but no significant difference was noted in the duration of erythema or crusting between the two sides (both P > 0.05). Compared with those before the treatment, skin texture scores decreased in both sides (both P < 0.05), and were significantly lower in the FFLT side than in the control side at 3 months after the treatment(P < 0.05). The erythema index was significantly lower in the FFLT side than in the control side in both scarred areas and non-scarred areas on day 1 after the treatment (both P < 0.05). Both melanin index and TEWL at the FFLT side were significantly increased in scarred areas, but decreased in non-scarred areas compared with those at the control side within 3 days after the treatment (all P < 0.05). Similarly, the water content of the stratum corneum at the FFLT side was significantly lower in scarred areas, but higher in non-scarred areas compared with that at the control side between day 1 and 7 after the treatment (both P < 0.05). No significant difference was observed in the erythema index, TEWL or water content of the stratum corneum between the FFLT side and control side at scarred areas or non-scarred areas(all P > 0.05)from 2 weeks to 3 months after the treatment(all P > 0.05). Conclusion FFLT can improve therapeutic outcomes in atrophic acne scars with reduced adverse reactions.
