Objective: To explore the relationship between the combinative intervention therapy and clinical curative effect, through used function magnetic resonance imaging (fMRI) to observe the change of detection data for patients with cerebral infarction pre and post-intervention therapy of acupuncture combined with traditional Chinese medicine (TCM). Methods: 40 patients with cerebral infarction were divided into control group (20cases, received normal treatment)and observation group (20cases, received combinative treatment of acupuncture and TCM). Pre and post therapy, the patients of every group received evaluation about state of illness and detection of fMRI. The score of national institute of health stroke scale (NIHSS) was used to evaluate the degree of neurologic impairment, and analyze the imaging manifestations of fMRI on patients with cerebral infarction at basal ganglia who received acupuncture combined with TCM. Some cerebral functional imaging techniques, included blood oxygenation level dependent( BOLD), fMRI and diffusion tensor imaging (DTI), were used to grasp the changes of relevant functional region of brain and different brain regions connected with function region of patients with cerebral infarction before and after therapy. Results: The NIHSS score of observation group was significantly less than that of the control group (t=5.450, P<0.05), and the total efficiency of observation group (95%) was significantly higher than that of the control group (75%) (x2=4.329, P<0.05). And the differences of the activation frequency, activation volume, ADCavg values and the values of FA between the observation group and the control group were statistically significant (t=5.425, 2.760, 3.453, 5.513, P<0.05). Conclusion: Acupuncture combined with traditional Chinese medicine can efficiently improve the status of neurologic impairment for patients with cerebral infarction, and the clinical efficacy before and after treatment can preferably be observed by fMRI.

OBJECTIVE To investigate deep fungal hospital infection and methods of its decreasing. METHODS Case histories of near 3 years of hospitalized patients from Jan 2002 to Dec 2004 were analyzed according to Diagnosis Standard of Nosocomical Infection under the items,such as the patients,age,underlying disease,sample,strain,and species distribution. RESULTS There were 360 fungus strains belonged to 15 species in all samples;the patients age was 14-94 with 20 kinds of various underlying diseases;the fungi included Candida albicans,and C.tropicalis,accounted for 61.1% and 17.2%,respectively;the samples were sputum,urine,vaginal secretion,BLA,throat swab and pus,which were 42.2%,21.1%,13.9%,8.4%,5.8%,and 3.6%,respectively;the respiratory department,ICU,and urology department were mainly involved. CONCLUSIONS To prevent fungal infection, measures such as hospital′s environment and management including reasonable use of antibiotics play a great role in monitoring hospital fungal infection and its epidemiology.

Objective To investigate MVD, TSP-1, TGF-?1 expression in GH-Secreting Pituitary Adenomas by immunohistochemistry, and to correlate data with clinical characteristics.Methods The protein expression of TSP-1, TGF-?1 in 48 surgical specimens (21 invasive cases; 27 non-invasive cases) of pituitary adenomas was measured using immunohistochemical method. The relationship between the expression and clinical properties was examined. MVD was measured by detecting CD34.Results Compared with the noninvasive group, no difference of expression of CD34(t=2.257; P=0.083) was observed. The expression of TSP-1 in invasive group was low. The expression of TGF-?1 was higher in invasive cases than that in noninvasive ones. The expression of TGF-?1 had positive correlations with MVD; but there was no correlation between the expression of CD34 and the invasion of pituitary adenomas. In addition, MVD count was not associated with the expression of TSP-1. Size, sex or rate of recurrence did not influence MVD and TSP-1 expression. Conclusion MVD values do not necessarily represent angiogenesis in pituitary adenomas. TGF-?1 may increase MVD, and TSP-1 does not affect MVD in pituitary adenomas and angiogenesis may be regulated by other pathway.

Objective: To understand knowledge and practice of influenza prevention and associated factors among primary and middle school teachers, and to provide a reference for conducting the relevant propaganda work of influenza. Methods: Stratified random cluster sampling method was used to select 858 primary and secondary school teachers from Huainan of Anhui Province to complete questionnaires on influenza prevention. Results: Television and radio broadcasting were the basic tools for teachers to acquire flu knowledge, with 74.12% and 80.00% of primary and secondary school teachers, respectively. The total awareness rate of influenza knowledge among primary and middle school teachers was 56.63% and 58.63%, respectively. The results of univariate analysis showed primary and secondary school teachers’ influenza awareness were significantly affected by regions and education levels. In addition, primary school teachers’ influenza awareness was significantly affected by full-time medical technicians or part-time medical workers, secondary school teachers’ influenza awareness was significantly affected by working years(P<0.05). The total formation rates of influenza-related health behavior between primary and secondary school teachers were 71.20% and 73.00%, respectively. The results of univariate analysis showed primary and secondary school teachers’ influenza health behaviors was significantly affected by regions, educational levels, full-time medical technicians or part-time medical workers and health training. Moreover, secondary school teachers’ influenza health behaviors was significantly affected by working years(P<0.05). Multivariate logistic regression analysis showed that whether the comprehensive scores of influenza knowledge and behavior were qualified was correlation with the regional and educational levels. Additionally, the factors whether it is a full-time medical technician or a part-time medical teacher also had an effect on the comprehensive score of behavior(P<0.05). Conclusion The influenza knowledge level and the health behavior formation rate in the primary and secondary school teachers need to be improved, the knowledge of influenza and the relevant influencing factors should be taken into consideration to take targeted health intervention measures to improve their ability to fight against influenza.

OBJECTIVE:To establish the HPLC fingerprints for Sini decoction and compare the differences of compositions of Sini decoction prepared by traditional decoction and modern machine decoction. METHODS:HPLC was performed on the column of Kromasil C18 with mobile phase of acetonitrile-0.1% phosphoric acid(gradient elution)at a flow rate of 1.0 ml/min,the detec-tion wavelength was 235 nm,column temperature was 30 ℃,and injection volume was 10 μl.

According to the verification,the fingerprint of 10 batches of Sini de-coction showed good similarity with reference fingerprint,and the similarity of 10 batches of Sini decoction was high,which was prepared by the 2 methods. CONCLUSIONS:The established fingerprint is specific and stable,and can provide reference for quali-ty evaluation and control for Sini decoction;and there are no obvious differences in the main chemical compositions of Sini decoc-tion prepared by traditional decoction and modern machine decoction.

Background and purpose:Anastomotic leakage and low anterior resection syndrome(LARS) are both common complications in dual-anastomosis for patients with low rectal cancer. The aim of this study was to observe and explore the signiifcance and role of vertical cutting of the closed distal rectum in dual-anastomosis for patients with low rectal cancer.Methods:A total number of 120 patients with mid-low rectal cancer who admitted to and completed laparoscopic rectal cancer resection in the Department of General Surgery, the First Afifliated Hospital of Soochow University from Feb. 2010 to Jun. 2014 were pair-matched into Groups A and B based on their gender,age, tumor size, the distance of lower edge to the dentate line and tumor staging, etc. For the 55 patients in Group A (observation group), the rectum distal end was closed vertically instead of horizontally while disposing “the ifrst intestinal anastomosis”, intestine-intestine anastomosis was conducted in an “end-corner” approach when dealing with “the second intestinal anastomosis”, upper corner (“dog ear”) of the closed line in the distal end of the rectum was removed, the lower corner (“dog ear”) of the closed line in the distal end of the rectum was removed using vascular occlusion clamp method, and the T-shaped interchanges (“dangerous triangle”) of stapled sutures formed after anastomosis were strengthened with absorbable suture. For the 65 patients in Group B (control group), laparoscopic dual anastomosis was conducted using conventional method, and the two “dog-ears” and “dangerous triangles” were kept without any treatment. The clinical outcomes of the two groups of patients were analyzed retrospectively. Results:In group A, It was convenient to complete the operation when the “dog ears” and “dangerous triangle” on the vertical line after cutting the closed distal rectum vertically by “end-corner” anastomosis. The axis of intestine formed a certain angle making the closed distal rectum into “ampulla” sample without “dog ears”. the “dangerous triangle” were strengthened with absorbable suture. In group B, The distal and proximal intestine located on the same axis after intestine-intestine anastomosis leaving two “dog ears” and a “dangerous triangle”. The general clinical data of patients in the two groups were comparable and not signiifcantly different (P>0.05). The two groups of patients showed no signiifcant differences in blood loss, postoperative drainage, postoperative anastomotic bleeding, anal exhaust time, and length of hospital stay (P>0.05). However, the operation time as well as the numbers of anastomotic ifstula occurrence, defecation, tenesmus and post-operation re-ostomy differed significantly (P<0.05).Conclusion:Vertical cutting of the closed distal rectum with dual anastomosis made the “new” intestine closer to the physiological bending and morphology of the rectum, meanwhile, it simpliifed the approach of removing “dog ear” and strengthening “dangerous triangle”, ifnally it signiifcantly reduced the incidence of post-surgical complications.

Objective To investigate the effects of pulsed electromagnetic fields (PEMF) on homing and proliferation-related genes of mouse osteoblasts.Methods 9 week-old C57BL/6 mice were treated with PEMF (70 Hz,1 mT) for 4～5 weeks,while mice in control group didn't not receive PEMF.Bone marrow cells of femurs and tibias were flushed out,and the bones were minced and incubated at 37 ℃ with a type Ⅰ collagenase.Bone associated mononuclear cells (MNCs) were isolated via density centrifugation with Lymphoprep.Magnetic cell sorting was used before flow-cytometric sorting,and the ALCAM+Sca-1-cells were collected.The homing and proliferation-related genes expressed in ALCAM+Sca-1-cells were detected with high throughput microarray and RT-PCR.Results The expression of Jag1 and Ang-1 in mouse osteoblasts increased under the effects of PEMF.Conclusions PEMF may have regulation effects on HSC (hematopoietic stem cell) survival through modulating the homing and proliferationrelated genes in ALCAM+Sca-1-osteoblasts.
