Objective To investigate the clinic value of procalcitonin( PCT)and c-reactive protein ( CRP)in differential diagnosis for febrile diseases. Methods One hundred and forty patients with febrile diseases in May 2009 to February 2014 in the No. 309th Hospital of People Liberation Army were investigated and analyzed retrospectively. Based on discharge diagnosis,patients were divided into bacterial infection group( n=58),non-bacterial infection group(n=47)and rheumatic diseases group(n=35),another 40 healthy people were served as the control group. Serum PCT and CRP were detected and compared in four groups. One month after backing to normal temperature in all the patients,detected serum PCT and CRP again. Results Serum PCT and CRP level in bacterial infection group,non-bacterial infection group,rheumatic diseases group and control group were(5. 18 ± 1. 92)and(0. 45 ± 0. 22),(0. 34 ± 0. 13)and(0. 16 ± 0. 05)μg/L,(25. 31 ± 4. 24), (1. 94 ± 0. 37 ),( 62. 32 ± 15. 10 ) and( 1. 30 ± 0. 04 ) mg/L respectively. Serum PCT and CRP level in bacterial infection group were significantly higher than that in control group(P﹤0. 01). Even though serum PCT and CRP level in non-bacterial group slightly higher than that of healthy control group,there was no statistical difference(P﹥0. 05). Serum PCT and CRP level in bacterial infection group were significantly higher than that of non-bacterial infection group( P ﹤0. 01 ). Serum CRP level in rheumatic diseases group was significantly higher than that of healthy control group( P﹤0. 01),while PCT level only slightly higher compared with healthy control group(P﹥0. 05). One month after backing to normal temperature in all the patients,serum PCT and CRP level in bacterial infection group reduced significantly compared with that of febrile period( P ﹤0. 01). Serum PCT and CRP level in non-bacterial infection group were no significant change( P﹥0. 05 ),and serum CRP level in rheumatic diseases group reduced significantly( P﹤0. 01 ),while serum PCT were no significant change(P﹥0. 05). Conclusion Serum PCT combined with CRP might be of great importance in the differential diagnosis for febrile diseases.

Objective To observe the effect of surface electromyographic biofeedback on the pharyngeal phase activities in patients with dysphagia after stroke. Methods Seventy-six consecutive patients with pharyngeal dysphagia after stroke admitted to the departments of rehabilitation and neurology,brain hospital affiliated to nanjing medical university from August 2014 to February 2015 were enrolled retrospectively. After excluding 40 patients,the remaining 36 patients were divided into either a conventional training group (n =19)or a biofeedback group (n =17)by using the random number table. The patients of the conventional training group received swallowing function training only,while those of the biofeedback group also received the surface electromyographic biofeedback treatment on the basis of the therapy program of the conventional training group. The patients of both groups were treated 6 times a week for 4 weeks. The assessment of swallowing angiography,the digital measurement and analysis were performed before and after treatment. The outcome measures included the degree of openness of upper esophageal sphincter (UES),0pharyngeal transit time (PTT),and the maximum displacement of the hyoid bone (HmaxD). Results (1)The proportions of UES complete opening of the conventional training group before and after training were 26. 3% (5 / 19)and 47. 4% (9 / 19)respectively. There was significant difference between before and after training (χ2 = 5. 08, P =0.020). The proportions of UES complete opening of the biofeedback group before and after training were 47.1% (8/ 17)and 82.4% (14/ 17)respectively. There was significant difference between before training and after training (χ2 =11.46,P = 0. 001). There was no significant difference in the degrees of UES complete opening before training between the conventional training group and the biofeedback group (P >0. 05). There was significant difference in the degree of UES complete opening after training between the 2 groups (χ2 =4. 63,P = 0. 040). (2)PTT of the conventional training group before and after training was 0.24 ±0.07 and 0.19 ±0.06 s respectively. PTT of the biofeedback before and after training was 0.23 ±0.06 and 0. 15 ± 0. 05 s. There was significant difference between before training and after training (F = 154. 50,P = 0. 000). There was no significant difference in PTT before training between the conventional training group and the biofeedback group (P > 0. 05). There was significant difference in PTT after training between the 2 groups (F =4.66,P = 0. 038). (3)The HmaxD distances of the conventional training group before and after training were 0. 5 ± 0. 4 and 0. 9 ± 0. 4 cm respectively,the PTT of the biofeedback training before and after training was 0. 6 ± 0. 4 and 1. 3 ± 0. 6 cm respectively. There was significant difference between before training and after training (F = 137. 56,P = 0. 000). There was no significant difference in the HmaxD distance of the conventional training group and the biofeedback training group before training (P > 0. 05). There was significant difference in the HmaxD distance after training between the 2 groups (F = 4. 29,P = 0. 033). Conclusion The surface electromyographic biofeedback therapy in combination with the conventional swallowing training for the treatment of dysphagia after stroke has the synergistic efficacy.

BACKGROUND: In lumbar spondylolisthesis patients with severe osteoporosis, screw is easily loose and pul s out during reposition, or loss of reduction and internal fixation failure easily occur after repair. Therefore, it is very important to elevate the intensity of pedicle screw fixation during repair. At present, few studies concern application of bone cement screw enhancement technology in lumbar spondylolisthesis patients with osteoporosis. OBJECTIVE: To investigate the clinical value of augmented pedicle screw with polymethylmethacrylate for lumbar spondylolisthesis accompanied with osteoporosis. METHODS: From June 2009 to June 2011, 27 patients suffering from lumbar spondylolisthesis accompanied with osteoporosis were included in this retrospective study. These patients received augmented pedicle screw with polymethylmethacrylate. The levels of disability and pain were evaluated by Oswestry Disability Index and visual analog scale. The internal fixation and fusion were evaluated by radiological findings. Al complications were recorded. RESULTS AND CONCLUSION: Al cases were fol owed up for 15-37 months. Oswestry Disability Index and visual analog scale scores were significantly better in final fol ow-up than that pre-treatment (P < 0.05). Imaging results revealed that bone cement tightly connected to bone interface. The position of screw and bone cement was good. Symptomatic bone cement leakage was not found. No fixation failure was detected during final fol ow-up. Al patients achieved interbody fusion. These results suggested that polymethylmethacrylate bone cement could increase the gripping force of the pedicle screw in osteoporotic vertebral body. It is safe and effective to treat spondylolisthesis accompanied with osteoporosis with augmented pedicle screws. Satisfactory fixation stability and interbody fusion can be obtained.

The primary importance of magnetic resonance (MR) imaging in evaluating anal fistulas lies in its ability to demonstrate hidden areas of sepsis and secondary extensions in patients with fistula in ano. MR imaging is relatively expensive, so there are many healthcare systems worldwide where access to MR imaging remains restricted. Until recently, computed tomography (CT) has played a limited role in imaging fistula in ano, largely owing to its poor resolution of soft tissue. In this article, the different imaging features of the CT and MRI are compared to demonstrate the relative accuracy of CT fistulography for the preoperative assessment of fistula in ano. CT fistulography and MR imaging have their own advantages for preoperative evaluation of perianal fistula, and can be applied to complement one another when necessary.

In order to clone and express alcohol dehydrogenase II (ADH2) gene from Saccharomyces cerevisiae in E. coli BL21 (DE3) efficiently, we extracted the total RNA as template and obtained ADH2 gene by RT-PCR and connected ADH2 gene to pTAT plasmids to gain recombinant expression plasmid pTAT-ADH2, then transformed this recombinant expression plasmid pTAT-ADH2 into E. coli BL21 (DE3). The recombinant was induced by IPTG to express ADH2. After purification, ADH2 activity was tested in vitro and toxicologic test was done in mouse. Sequence test showed that the acquired fragments exhibited 90% homology to ADH2 gene sequence from GenBank report. The target gene expressed efficiently and took up to approximant 50% of total protein by SDS-PAGE and band scanning analysis. The purified protein exhibited the identified activity through biochemical test and mouse toxicological test. As a result, the acquired ADH2 gene was highly homology to the published sequence and expressed at a high level in E. coli BL21 (DE3), more importantly, ADH2 proved to have ethanol dehydrogenase activity.

Objective To observe the relationship between CYP2C19 gene polymorphisms and major adverse cardiovascular events in the patients of acute coronary syndrome (ACS) who accepted percutaneous coronary intervention (PCI) in Han population from Dalian. Methods A total 809 cases with ACS who had undergone PCI in the cardiology department of Dalian Municipal Central Hospital from Janurary 2012 to Janurary 2014 were selected,Among 809 cases of ACS,there were 178 cases of acute ST segment elevation myocardial infarction (STEMI),105 cases of acute non ST segment elevation myocardial infarction (NSTEMI) and 526 cases of unstable angina. The patients were divided into three groups according to their CYP2C19 genotype.CYP2C19 genotype (*1/*1) were classified as extensive metabolizers (EM group), CYP2C19 genotype (*1/*2、*1/*3) were classified as intermediate metabolizers (IM group) and CYP2C19 genotype (*2/*2、*3/*3、*2/*3) were classified as poor metabolizers (PM group). The occurrence of major adverse cardiovascular events at least 24 months was observed. Results Seven hundred and ninety patients finished the follow-up at least 24 months, 19 patients lost in follow-up, 350 cases (43.2%) were CYP2C19 (*1/*1),318 cases (39.3%) were CYP2C19(*1/*2), 42 cases(5.2%) were CYP2C19 (*1/*3),77 cases (9.5%) were CYP2C19 (*2/*2), 21 case(2.2%)were CYP2C19 (*2/*3), and 1 case (0.1%) was CYP2C19(*3/*3), 350 cases (43.2%) were classified as EM group, 360 cases (44.5%) were classified as IM group, and 99 cases(12.2%)were classified as PM group. No significant difference in age, gender, hypertention, diabetes mellitus, smoking was shown among three groups (P > 0.05). The rate of MACE were 3.3% , 8 cases had target lesion revascularization(EM group 3 cases, IM group 3 cases, PM group 2 cases), 2 cases had non-fatal myocardial infarction (IM group 1 case, PM group 1 case), 15 cases were died(EM group 6 cases, IM group 7 cases, PM group 2 cases), 1 case had subacute stent thrombosis in IM group. The rates of MACE were higher in PM group (5.1%) than those in EM group(2.65%) and IM group (3.41%) , but there was no significant difference in three groups (P>0.05). There was no significant difference in the rate of target lesion revascularization , thrombus in stent, non- fatal myocardial infarction and death among three groups(P > 0.05). Conclusions There is no significant correlation between CYP2C19 gene polymorphism and long-term prognosis in patients with ACS who accepte PCI treatment in Han population from Dalian.
