ObjectiveTo discuss the effect of evidence-based nursing on prevention of pulmonary complications in postoperative elderly lung cancer patients.MethodsTwenty elderly lung cancer patients from January to June 2010 were randomly divided into the observation group and the control group with 10 patients in each group.The control group was given regular care methods.The observation group received evidence-based clinical nursing methods.The preventive effect of pulmonary complications was observed in both groups.ResultsOne case was found to have pulmonary complications in the observation group,while four cases in the control group.The total cure rate of the observation group was higher than that of the control group.ConclusionsEvidence-based nursing methods can satisfy the medical demand of patients and their family members to the utmost degree,reduce the incidence of pulmonary complications and contribute to the early recovery of patients.It is worthy of clinical application.

To observe the therapeutic effect of acupuncture and moxibustion on the climacteric syndrome, patients with climacteric syndrome were treated by acupuncture and moxibustion and randomly compared with the patients in control group treated by Chinese herbs. There was a significant difference between two groups (P＜0.05). The results showed that the therapeutic effect in acupuncture and moxibustion group was obviously better than that in Chinese herbs group.

Teaching in classroom is an essential pattern of clinical theoretic education. Evaluation, which is one of the most available methods to monitor and manage the teaching quality is simultaneously an effective way to build up a teaching group and train the teacher. The evaluating system should include students' opinions, companion's advice and experts' instruction. It is very important for making the evaluating more scientific, more significant and more accurate.

Objective To investigate the characteristics of the cognitive impairment about attentional network among amphetamine-induced psychiatric disorders. Methods Amphetamine-induced psychiatric disorders ( n = 100) and normal controls ( n = 100) were assessed with Attentional Network Test(ANT) in the first week and the fourth week. Results Compared with the control group, the first ANT's response time was significantly increased, and the correct rate, orienting and executive control network were significantly reduced in Amphetamineinduced psychiatric disorders( eg:response time ( 867. 37 ± 272.24 ) ms vs ( 668.56 ± 136. 20 ) ms, correct rate (0.88 ±0.06 ) ms vs (0.88 ±0.06) ms ,orienting( - 217.86 ± 198.00 ) ms vs ( -59.67 ± 85.07 ) ms and executive control network ( 184.74 ± 66.61 ) ms vs ( 74.71 ± 50.77 ) ms, P ＜ 0.01 ), but the alerting network was higher ( ( 151.17 ± 198.27 ) ms vs (50.60 ± 67.47 ) ms). In the second ANT results, there was no significant difference between two groups. Compared with the first ANT results of amphetamine-induced psychiatric disorders, the second ANT had shorten response time ,that the correct rate, orienting and executive control network were significantly increased(P ＜ 0.01 ). Conclusion These results suggest that amphetamine-induced psychiatric disorders have impairment in cognitive function, but these impairment can be recovered within one month.

Objective To investigate the effects of early Xuebijing injection on procalcitonin (PCT) with septic shock patients.Methods Sixty-five patients with septic shock were randomly divided into the control group and Xuebijing injection group.The patients in Xuebijing injection group were received Xuebijing injection therapy(50 ml Xuebijing + 100 ml 0.9％ NaCl injection,2 times/d,for 7 d) besides basic treatment,while in the control group were received basic treatment including antibiotic susceptibility + early fluid resuscitation + correct acidosis.At the entering the ICU day and 1,3,5 d after treatment,patients were collected 5 ml venous blood serum C reactive protein(CRP) and PCT,and before treatment and at the 5th,7th day after treatment conducted APACHE Ⅱ evaluation to observation of curative effect of two groups.Results Before treatment,there were no significant difference in terms of heart rate,blood pressure,PCT,CRP,APACHE Ⅱ scores between the two groups (P ＞ 0.05).There was no significant difference in terms of PCT and CRP between the two groups at the 1 d after treatment(P ＞0.05).While at the 3th day after treatment,PCT and CRP of Xuebijing group were lower than of control group and the differences were significant ((7.37 ± 2.58) μg/L vs.(12.25 ± 3.32) μg/L,(64.32 ± 11.12) mg/L vs.(72.37 ± 12.42) mg/L;P ＜0.05).The APACHEⅡ score in control group at before and 5th,7th day after treatment were (20.48 ± 4.41),(16.52 ± 3.45),(12.78 ± 2.91) respectively,in Xuebijing injection group were (20.74 ± 4.73),(12.48 ± 2.76),(9.24 ± 6.67) respectively.And all indices were significant different time points between groups (P ＜ 0.05).At 7th day after treatment,15 cases were improved,10 cases progressed and 8 cases died in the control group and the effect rate was 75.8％ (25/33).Meanwhile,22 cases were improved,5 cases progressed and 5 cases died in the Xuebijing group and effect rate was 84.8％ (27/32).There was significant difference between two group(x2 =7.27,P =0.03).Conclusion Early Xuebijing injection application can inhibit the PCT r~tion of septic shock patients and improve the prognosis.

The change of hemodynamics and hemorrheology induced by hypoxia challenge in the dog were investigated. The results showed that hypoxia caused significant decrease of cardiac output,increased pulmonary artery pressure and pulmonary vascular resistance. Hypoxia also caused increase of blood viscosity. In terms of changes of the reduced viscosity is directly related to the deformation and agglutination properties of red blood cells.

[ ABSTRACT] AIM:To investigate the role of hydrogen sulfide ( H2 S) on impaired wound healing in ob/ob mice and the underlying mechanism.METHODS:The ob/ob mice were randomly divided into 3 groups, including vehicle, in-sulin and NaHS for treatment.C57BL/6 mice were treated with vehicle as control.Full-thickness punch biopsy wounds were created on the mice.Firstly, H2 S concentrations in the skins and granulation tissues were measured.The mRNA ex-pression of cystathionineγ-lyase ( CSE) was detected by RT-qPCR.The protein expression of CSE and MMP-9 were deter-mined by Western blot.The neutrophil and monocyte/macrophage infiltration was analyzed by immunohistochemistry me-thod.The levels of tumor necrosis factor (TNF)-αand interleukin (IL)-6 were measured by ELISA.Collagen formation was measured by Masson staining.RESULTS:The H2 S levels in the skin and granulation were significantly decreased in ob/ob mice and increased in the NaHS-treated mice ( P<0.05 ) .CSE expression at mRNA and protein levels was significantly decreased in ob/ob mice compared with the control mice (P<0.05).The wound healing period was significantly shorter in NaHS group than that in vehicle-treated ob/ob mice group (P<0.05), in which the insulin group had no difference with vehicle ob/ob mice group.The neutrophil and monocyte/macrophage infiltration, and TNF-αand IL-6 levels were signifi-cantly increased in ob/ob groups, but were decreased in NaHS group ( P<0.01 or P<0.05 ) .Meanwhile, NaHS in-creased collagen formation in the granulation tissues of ob/ob mice.CONCLUSION:H2 S/CSE down-regulation contributes
to impaired wound healing in diabetes, which is alleviated by exogenous H2 S possibly through anti-inflammation.

Objective To investigate COL1A1 gene mutation by PCR-high resolution melting (PCR-HRM) and an-alyze the correlation between genotype and clinical phenotype in a child (proband) with osteogenesis imperfecta (OI). Methods The family history of OI pedigree along with the clinical data was collected. Blood samples from the proband and his family members, as well as 50 normal controls, were collected. The mutation of COL1A1 gene was screened using PCR-HRM and validated by the gene sequence. Results The detection of PCR-HRM showed the abnormal result of COL1A1 17 exon in proband with a lower melting temperature (Tm) value than that of normal controls by 0.4℃. There were signifi-cant differences in the standardization melting curve and the different melting curve between the proband and the normal controls. The sequencing result was c.1138G>A, which meant that cDNA of 1138 base G mutation into A. The mutations transformed the amino acid glycine into a serine at amino acid 380(P. Gly 380 Ser), which resulted in missense mutations. The proband’s father and grandmother had the same mutation of COL1A1 gene. The mutation was not found in the proband’s mother and normal controls. There was no report for such mutation in Chinese population. Pedigree analysis showed the fami-ly genetic characteristics of autosomal dominant inheritance. The proband was clinically diagnosed as OI type Ⅳwith more severe clinical phenotype. Conclusion PCR-HRM analysis is a new effective method for genetic screening of OI. COL1A1 mutation of c.1138G>A is a newly discovered mutation in Chinese population. Gly replaced inαhelical domain may lead to a more severe clinical phenotype.

Objective To investigate the alterations and phenotypes of dendritic cells, inflamma-tory monocytes and macrophages in immunocompetent mice during Pneumocystis murina ( P.murina) infec-tion for further analysis of the function of these cells during P.murina infection.Methods Wild type male C57BL/6 mice at age 6-8 weeks were randomly divided into two groups including the group with P.murina infection and the group receiving sham surgery.The mice without any intervention were used to set up the blank control group.The loads of P.murina strains in lung tissues of each mouse were quantified by TaqMan real-time fluorescence polymerase chain reaction after the infection.Histopathological examination was per-formed to evaluate the degree of inflammation in lung tissues.The numbers of dendritic cells, inflammatory monocytes and macrophages in lung tissues, peripheral blood and bone marrow samples, and the changes of inflammatory monocytes in spleen tissues were measured by flow cytometry analysis.The expression of major histocompatability complexⅡ(MHCⅡ), CX3C chemokine receptor 1 (CX3CR1) and CC chemokine re-ceptor 2 ( CCR2 ) by dendritic cells, inflammatory monocytes and macrophages in lung tissues during P.murina infection were analyzed by flow cytometry analysis.All of the data were collected one, two, three and four weeks after the corresponding treatments.Results The loads of P.murina strains in P.murina in-fected mice were elevated after two and three weeks infection, but decline at week 4 (P>0.05).Significant pathological changes including the alveolar destruction, inflammatory cell infiltration and thickened alveolar septum in mice with P.murina infection were observed under a microscope at week 3 and week 4.Compared to the sham surgery treatment group, the number of CD11c+CD11b+dendritic cells were increased in lung tissues, but decreased in blood samples during P.murina infection ( P<0.05) .The levels of inflammatory monocytes in blood samples fell at week 3 and then rose at week 4 during P.murina infection (P<0.05). No significant difference with the change of macrophages in mice was observed during P.murina infection ( P>0.05).The CD11c+CD11b+dendritic cells in lung tissues of mice with P.murina infection expressed high levels of MHCⅡand CX3CR1, and low levels of CCR2.The inflammatory monocytes in lung tissues of mice expressed high levels of CCR2, moderate levels of MHCⅡand low levels of CX3CR1 during P.murina in-fection.High levels of CX3CR1 and low levels of MHCⅡ and CCR2 were observed in macrophages from lung tissues of mice with P.murina infection.Conclusion Highly expressed CD11c+CD11b+dendritic cells and MHCⅡwere detected in lung tissues of mice during P.murina infection, indicating that CD11c+CD11b+dendritic cells were involved in the host defense against P.murina infection.

Objective To investigate the risk factors affecting prognosis in elderly patients with septic shock and explore the effective treatment. Methods A retrospective study of 147 patients with septic shock from the Affiliated Hospital of Hebei United University and Affiliated People's Hospital from Jan. 2011to Jan. 2013 was conducted. Early fluid loading was defined as the administration with an initial fluid bolus within 6 h in ICU. Conservative fluid management was defined as negative fluid balance measured in at least 1 d during the first 3 d as the case group,while the daily fluid balance and cumulative daily fluid balance of the first 3 d was as the control group. The effects of early fluid management on prognosis of elderly patients septic with shock combining the living index within 7 d in ICU were recorded. Results In the case group with 7 d ICU,21. 4%(15 / 70)patients were in progressed and 37. 1%(26 / 70)patients were dead,while 25. 9%(20 / 77)patients were in progressed and 59. 7%(46 / 77)patients were dead in control group(χ2 = 13. 17,P = 0. 00). Univariate analysis showed that APACHEⅡ scores,SIRS score,organ failure,patients with chronic diseases related were associated with 7 d survival rate in elderly patients with septic shock. Multivariate Logistic regression analysis showed that higher APACHEⅡ scores and SIRS score,organ failure,patients with chronic diseases related (have)were the risk factors(OR = 1. 88,5. 34,1. 96 and 4. 76;P < 0. 05). The restrictive fluid management strategy have related with the septic shock patients in elderly that the OR of death rate of fluid management in elderly patients with septic shock was 0. 657(P = 0. 032). Conclusion The prognosis in elderly patients septic with shock is associated with APACHE Ⅱ scores,SIRS score,organ failure,patients with chronic diseases related. Early fluid management can improve to the prognosis of elderly patients with septic shock.
