Objective To study the value of detection of C- reactive protein(CRP), serum glucose concen-tration and APACHE Ⅱ grade for estimating inflammation, pathogenetic condition and prognosis of systemic inflam-matory response syndrome (SIRS) patients.Methods 50 SIRS patients in ICU were selected and were divided into S1 and S2 subgroup according to SIRS diagnosis standard, and 18 patients developed MOBS.30 patients without SIRS, were selected as control group.Detection of CRP, serum glucose concentration and APACHE Ⅱ grade were per-formed.Results CRP(76.19±11.98 mg/L vs.14.04±5.70 mg/L) ,serum glucose concentration(7.10±1.30 mmol/L vs.5.32±1.09 mmol/L) and APACHE Ⅱ grade (20.06±6.39 vs.7.90±3.54) of SIRS group were higher than that of non-SIRs group (P<0.01).CRP, serum glucose concentration and APACHE Ⅱ grade all are higher in group S2 than that of group S1 (91.25±9.89 mg/L vs.62.29±10.38 mg/L,8.32±2.40 mmol/L vs.7.10±1.69 mmol/L,26.72±5.14 vs.18.37±5.70).MOBS incidence and case fatality in S2 subgroup (12/15 and 6/35) were higher than that of S1 subgroup(10/15 and 3/35 ) (P<0.01 ).Conclusion CRP, serum glucose concentration and APACHE Ⅱ grade are increased in SIRS patients and with their increasing, MOBS incidence and case fatality were also increasing.CRP, serum glucose concentration and APACHE Ⅱ grade are significant factors in estimating SIRS patients pathogenetic condition and their prognosis.

In the present study, the fusion gene lipL32/1-lipL41/2 from Leptospira interrogans was constructed by using PCR with linking primers, expressed in prokaryotic expression system. And the immuno-reactivity of its expressed product was determined. Meanwhile, SDS-PAGE and BioRad agarose image analyzer system was used to examine the expression output of the target recombinant protein rLipL32/1-LipL41/2, and the immune-reactivity of this recombinant protein was identified by Western blot assay. ELISA was used to detect the level of antibodies against the recombinant proteins in sera of patients with leptospirosis. It was demonstrated that the percentages of similarity in nucleotide and the putative amino acid sequences of the fusion gene lipL32/1-lipL41/2 with the corresponding sequences previously reported were 99. 9% and 98. 9%respectively. The expression output of the target recombinant protein was approximately 10% of the total bacterial proteins.Both the rabbit antisera against rLipL32/1 and rLip41/2 could recognize and combine to the recombinant fusion protein rLip32/1-Lip41/2 as well. The positive rates of antibodies in 228 leptospirosis patients with the recombinant proteins rLip32/1,rLip41/2 and rLip32/1-Lip41.2 were 97.4%, 78. 5% and 99. 1% respectively. The results of the present study leads to the conclusion that the fusion gene lipL32/1-lipL41/3 with its prokaryotic expression system is successively constructed and the expressed recombinant protein shows excellent immuno-reactivity, thus suggesting that it may be used as the antigenic candidate for the development of the leptospiral genus-specific engineering vaccine and for the preparation of diagnostic kits.

The therapeutic effects and mechanisms of traditional Chinese kidney-tonifying drugs in treating osteoporosis have become the focus under study. Pharmacological studies have shown that traditional Chinese kidney-tonifying drugs are promoters for the proliferation of osteoblasts, inhibitors for the activity of osteoclasts, regulators for the estrogen level and its receptor, plays important roles in promoting osteogenesis and suppressing adipogenesis of marrow mesenchymal stem cells (MSCs), modulating the function of OPG/RANK/RANKL system and the metabolism of calcium and phosphorus, as well as antioxidation. The anti-osteoporotic active ingredients and pharmacological action mechanism of traditional Chinese kidney-tonifying drugs are summarized from the perspective of molecular and cell biology in this paper, so as to provide references for the study of their mechanism of anti-osteoporosis and for the development of traditional Chinese kidney-tonifying and bone-strengthening drugs.

Objective To explore the bone mineral density (BMD) status and its influencing factors in schizophrenia patients in order to provide basis for risk assessment in psychiatric nursing.Methods A total of 1,139 hospitalized schizophrenia patients were recruited and assigned into the medication group (n=652) and the non-medication group (n=487) according to previous antipsychotic drug history.T-score and Z-score of BMD were determined using Sunlight Omnisense 7000S Bone Densitometry.Blood calcium,blood phosphorus and serum prolactin levels were measured using fasting blood of ulnar vein.Results Differences in age,BMD,milk intake,level of activity,level of smoking,history of fall,history of fracture,serum Ca2+ and PRL were statistically significant between two groups(P＜0.05);there were significant differences in BMD rank distributions among schizophrenia patients with different courses of disease and lengths of taking antipsychotics (P＜0.001);multiple linear regression showed that influencing factors of BMD with statistical significance were courses of disease,lengths of taking antipsychotics,serum Ca2+,serum PRL,milk intake,level of activity,and level of smoking.Conclusion The BMD was lower in the medication group than that in the non-medication group,and the development of osteoporosis was correlated to various factors.Clinical nurses should master high-risk factors thoroughly and adopt intervention measures in a timely manner.

Dexamethasone is a synthetic glucocorticoid that is widely used in clinical due to its multiple pharmacological effects. Recently, dexamethasone is increasingly utilized in anti-cancer therapy. It is frequently used to prevent side effects of chemotherapy such as nausea, vomiting and pain, as well as to increase the anti-tumor activity of the cancer chemotherapeutic agents as a chemosensitizer and to inhibit tumor growth as an anti-cancer agent in some certain cancers. Dexamethasone produces the effects in anti-inflammation, anti-angiogenesis, control of estrogen activity and so on, by binding to glucocorticoid receptor to regulate gene expression of some important bio-signal molecules. Those signal pathways could interfere with the transcription of various factors which can regulate proliferation, invasion and metastasis of tumors.

OBJECTIVETo explore significance of preoperative color Doppler flow imaging (CDFI) for screening deep vein thrombosis in upper limbs fracture.

METHODSFrom January 2009 to December 2011, 1200 patients with upper limb fracture caused by trauma were respectively analyzed. There were 833 males and 367 females,ranging from 20 to 78 (mean 41.94 +/- 15.41) years. All patients had swelling and pain in injured limbs when enrolled. CDFI was used to examine upper limbs vein at 3 to 10 d after improvement of swelling, 1 day before reduction. Relationship among occurrence of thrombosis, gender, age and fracture sites were analyzed. Patients with DVT were analyzed with respective study to decide whether combined with diabetes, hypertension and hyperlipidemia.

RESULTSAll patients were checked by CDFI,which confirmed 9 cases with DVT. The rate of thrombosis was 0.75%, women than men (P < 0.01). The risk of blood clots occurred over 30 years, and the occurrence of thrombosis in humerus fracture was higher than radius ulnar fracture. One of 9 patients combined with hypertension and hyperlipidemia, 1 case combined with diabetes, and 7 cases with no complication.

CONCLUSIONUpper trauma fracture may occur deep vein thrombosis; CDFI should be used to check DVT in qualified hospital,which can maintain medical safety,decrease occurrence of medical disputes, and ganrantee patient's safety.
