Objective To investigate the static postural balance of patients with lumbar disc herniation (LDH). Methods From January to September, 2015, thirty patients with LDH were as observation group, and thirty healthy adult people were as control group. Their bal-ance function were detected and compared. Results The sway length, sway area and anteroposterior sway velocity were higher in the obser-vation group than in the control group (t>2.262, P<0.05), but there was no significant difference in mediolateral sway velocity between two groups (t=1.946, P=0.057) in eye-open condition. All of the indexes were higher in eye-closed condition in the observation group than in the control group (t>2.767, P<0.01), as well as the Romberg values (t>2.326, P<0.05). Conclusion Impairment of the proprioception and lower back pain affected the postural control of patients with LDH, who relied more on vision input to maintain postural stability.

Objective To discuss the diagnosis and management of tracheomalacia complicating large goiter. Methods Clinical data of 36 patients with large goiter complicated by tracheomalacia at Xijing Hospital between 1992 and 2004 were retrospectively reviewed. Preoperative Valsalva-Mueller test were performed in all patients before undergoing subtotal thyroidectomy with tracheal suspension, and two patients were treated by subtotal thyroidectomy with tracheal suspension and tracheostomy. Results Valsalva-Mueller test was positive in all patients. The compressed tracheal cartilage disappeared in 2 cases, became thin and soft in other 34 cases. Thirty-four patients who underwent subtotal thyroidectomy with tracheal suspension recovered and 2 patients were resued by tracheal suspension with tracheostomy. There was no mortality. Postoperative 34 cases were followed-up from 6 months to 13 years. Thirty-two cases had no postoperative respiratory obstruction, 2 patients died of unrelated diseases. Conclusions The diagnosis of tracheomalacia from large goiter is based on Valsalva-Mueller test and operative detection. Subtotal thyroidectomy with tracheal suspension is the treatment of choice for tracheomalacia complicating large goiter.

Objective To discuss the diagnosis, selection of type of operation, and prevention and treatment of perioperative complications of abdominal aortic aneurysm (AAA). Methods The clinical data of 96 (patients) who underwent open surgical treatment of AAA, at Xijing Hospital between January, 1990 and June, 2004 were retrospectively reviewed. Among those, 82 patients with infrarenal AAA underwent aneurysmectomy and graft repair. 12 cases were treated by aneurysmal wrapping with Dacron. In 2 patients with suprarenal false AAA, lateral aneurysmectomy and repair was performed. Results The distance between renal artery and the neck of the aneurysm was determined by arteriography, MRA or EBT. Ninty-three patients were cured, and three cases died, with an operative mortality of 3.1%(3/96). The operative mortality was 50.0%(2/4) in 4 cases who had urgent operation because of ruptured AAA, while the operative mortality rate of the cases undergoing elective surgical repair was 1.1%(1/92, P

Rotavirus capsid protein Vp4 plays an important role in the virus adhering and entering the cells. In this study, a Vp4 gene cloned from a rotavirus strain TB-Chen was highly expressed in E.coli BL21 (DE3). The results of the Western blot showed that the protein possesses specific immuno-reactivities and can be specifically recognized by guinea pig antibodies against rotavirus strain SA11 or Wa. Some Vp4 dimers were formed during renaturation. These data obtained from this study provide a strong basis for further study on the structure and function of the Vp4.

By retrieving the clinical research literature of treatment functional dyspepsia by traditional Chinese medicine (TCM) from January 2004 to December 2014 based on China National Knowledge Internet (CNKI), we would establish a TCM decoction database for treating functional dyspepsia in this study. One hundred and sixty-four literature were included, involving 159 prescriptions, 377 medicines, in a total of 1 990 herbs. These herbs can be divided into 18 categories according to the effectiveness; and qi-regulating herbs, blood circulation herbs, and antipyretic herbs ranked top three ones according to the frequency of usage of the herbs, whose medicine usage frequency accounted for 51.81%. Usage frequency of 16 herbs was over 30, and Atractylodes, Radix, Poriaranked top three according to the usage frequency. Medicinal properties were divided into 9 kinds according to the frequency statistics, and the top three were warm, flat, and cold. Taste frequency statistics were classifiedinto 9 kinds, and the top three were acrid, sweet, and bitter. In frequency statistics of the meridian tropism of herbs, it was classifiedinto 11 kinds, and the top three were spleen, stomach, lung. The analysis can provide a reference for treatment and study of TCM of functional dyspepsia.

Objective To evaluate the value of echo‐contrast RT‐3DE for assessment of left ventricular volume and function in patients with left ventricular non‐compaction(LVNC) .Methods Twenty‐one patients of LVNC were involved and underwent non‐enhanced and contrast‐enhanced RT‐3DE to evaluate left ventricular end‐diastolic volume (LVEDV) ,left ventricular end‐systolic volume (LVESV) ,left ventricular ejection fraction (LVEF) .The endocardial border definition of LV was graded for each of the 16 LV segments as follows :0 = border invisible ,1 = border visualized only partially ,and 2 = complete visualization of the border .Three image‐quality groups (good ,fair ,and uninterpretable) were identified . Results ①Duringcontrast‐enhancedRT‐3DE,ascomparedwithnon‐enhancedRT‐3DE,thenumberof segments with complete visualization of the endocardial border increased significantly (55% vs 82% ,P <0.01) ,and the number of patients with a good‐quality echocardiogram increased significantly (33% vs 81% , P <0.01) .②Contrast‐enhanced RT‐3DE provided significantly larger values of LVEDV ( P < 0 0.1) and LVESV ( P < 0 0.1) as compared with non‐enhanced RT‐3DE ,the values of LVEF were not statistically different between the two techniques ( P =0.07) .③Intra‐and inter‐observer agreement for assessment of LV volumes and systolic function improved during contrast‐enhanced RT‐3DE ,as compared with non‐enhanced RT‐3DE .Conclusions Contrast‐enhanced RT‐3DE can increase the prevalence of good‐quality echocardiograms and significantly improve the reproducibility of LV volumes and function measurements .

Objective To investigate the changing pattern of antimicrobial resistance among gram-negative bacilli isolated from respiratory intensive care unit (RICU) for rational use of antimicrobial agents.Methods Antimicrobial susceptibility of 1 047 isolates of gram-negative bacilli from 2000 to 2004 was tested by disk diffusion method.WHONET 5.3 software was used to analyze the data.Results The most common pathogens were Pseudomonas aeruginosa (42.9%),Stenotrophomonas malto- philia (17.1%),Acinetobacter baurnannii (10.0%) and Klebsiella pneumoniae (6.5%).The susceptibility rate of P.aerug- inosa was relatively higher to ceftazidime (50%-74%),amikacin (33.3%-81.0%),piperacillin-tazobactam (30.4%-64.6%) and cefoperazone-sulbactam (33.5%-47.5%),while the susceptibility to imipenem decreased.The susceptibility rate of S. maltophilia was relatively higher to cefoperazone-sulbactam (47.2%-78.6%) and ticarcillin-clavulanic acid(28.3%-86.6%). More than 90% of Acinetobacter baumannii isolates were susceptible to imipenem.The susceptibility rates of K.pneumoniae to imipenem and cefepime were 92.9%-100% and 55.6%-80.0%,respectively.The susceptibility rate to piperacillin-tazobac- tam decreased from 58.3% to 21.7%.The prevalence of extended-spectrum?-lactamases (ESBLs) in K.pneumoniae increased from 11.1% in 2002 to 47.8% in 2004.Conclusions Most pathogens show significant resistance to the most commonly used an- tibiotics.It is very important to select antibiotics for the treatment of infections in ICU based on the results of susceptibility.

Proper chromosome separation in both mitosis and meiosis depends on the correct connection between kinetochores of chromosomes and spindle microtubules.Kinetochore dysfunction can lead to unequal distribution of chromosomes during cell division and result in aneuploidy,thus kinetochores are critical for faithful segregation of chromosomes.Centromere protein A (CENP-A) is an important component of the inner kinetochore·plate.Multiple studies in mitosis have found that deficiencies in CENP-A could result in structural and functional changes of kinetochores,leading to abnormal chromosome segregation,aneuploidy and apoptosis in cells.Here we report the expression and function of CENP-A during mouse oocyte meiosis.Our study found that microinjection of CENP-A blocking antibody resulted in errors of homologous chromosome segregation and caused aneuploidy in eggs.Thus,our findings provide evidence that CENP-A is critical for the faithful chromosome segregation during mammalian oocyte meiosis.

Spleen kidney Yang deficiency (SKYD) diarrhea is a common syndrome in tranditional Chinese medicine (TCM). Until now, there is not an ideal SKYD diarrhea rat model for the research. In this study, we compared single factor way (method I, injecting hydrocortisone and gavaging Sennae Folium) with compound factors way(method II, gavaging adenine, improper diet, exhaustion, and gavaging Sennae Folium) on establishing SKYD diarrhea rat model. After modelling, diarrhea index, D-xylose excretory rate, NOS/cGMP signal transduction system, organ index and histopathology examination were used to evaluate the two ways. The results showed that, compared with health group, all the assessment criterias of method I and method II had significant differences (P < 0.01, 0.05). In addition, the index such as diarrhea index, NOS/cGMP signal transduction system, organ index (kidney, testis and thymus) and histopathology examination had significant differences (P < 0.01, 0.05) between method I and method II. In conclusion, the compound factors modelling method better conforms to the symptom of diarrhoea model caused by SKYD. This new modelling method provides a basis for studying on TCM astringents warming and tonifying the spleen and kidney, relieving diarrhea.
