It is critical to preventing gut-originaltel infection to attenuate bacterial and/or endotoxin translocation, maintain bacterial balance, improve gut mucosal barrier function and elevate local immunity. Probiotics beneficially affect the host by improving its intestinal microbial balance, by preventing gut mucosal barrier breakdown and bacterial translocation, by modulating immunity,and by promoting gut movements and absorption. The role and new progress of probiotics in enteral nutrition are reviewed .

AIM: To analyze factors affecting on adverse drug reactions (ADRs) in 122 cases, in order to avoid and reduce occurrence of ADRs. METHODS: The cases of ADRs by the pharmacist and the clinical reports were collected, and then counted up and analyzed. RESULTS: In 122 cases of ADRs, there were 11 severe cases, the others are ordinary. The most common clinical displays of ADRs were the lesion of skin and the append ants ( 50.82 %), followed by the lesion of digestive system ( 20.49 %) and nervous system responses ( 18.03 %). Anti-infective drugs showed the highest proportion of ADRs, accounting for 61.48% of the total. The affected patients ranged in age over 50 years ( 34.42 %) and low age ( 21.32 %). The most of ADRs were induced by IV drop ( 91.96 %). CONLUSION: For the child and the old man crowd clinical doctors must be prudent with the medicine, avoiding the unreasonable combination of the medications, use the anti-infective drugs reasonably and strengthen monitoring of its use, in order to reduce occurrence of ADRs.

The excitability of cerebral cortex will change after the onset of ischemic stroke.Repetitive transcranial magnetic stimulation (rTMS) can be used to regulate the excitability in cerebral hemisphere cortex and promote the motor function recovery in patients with ischemic stroke.Studies have shown that both the affected hemisphere low-frequency rTMS and the unaffected hemisphere high-frequency rTMS can promote the motor function recovery in patients with ischemic stroke.The former may be more effective than the

Objective To investigate the mortality and cause of death in inpatients with cerebral infarction. Methods The clinical data of 515 patients with cerebral infarction as the underlying cause of death from January 2005 to December 2009 were analyzed retrospectively. The hospital mortality, direct cause of death,and constituent ratio of the cause of death were calculated. The clinical features,such as classification of the Trial of Org 10 172 in acute stroke treatment( TOAST),age and duration of hospital-ization were analyzed. Results ( 1 )The hospital mortalities in patients with cerebral infarction from 2005 to 2009 were 2. 0%(91/4 659),2. 1%(110/5 264),1. 9%(95/5 035),1. 2%(100/8 656),and 1. 0%(119/11 640),respectively. The overall mortality rate was 1. 5%(515/35 254),basically had a declining trend year by year(χ2 =42. 39;P<0. 01).(2)The mortalities of the inpatients with cerebral infarction in the young( <45 years),middle-aged(45 to 59 years),elderly(60 to 74 years),and aged ( >74 years)groups were 1. 1%( 22/2 009 ),1. 0%( 112/11 158 ),1. 5%( 221/14 311 ),and 2. 1%(160/7 776),respectively. They increased with increasing age(P<0. 01).(3)The TOAST classification in 515 died patients were as follows:57. 3%(n=295)for large-artery atherosclerosis,19. 4%(n=100) for cardioembolism,14. 4%(n=74)for cryptogenic stroke,7. 0%(n=36)for small-artery occlusion and 1. 9%(n=10)for other reasons. The five leading direct cause of death were cerebral hernia 49. 3%(n=254),primary central respiratory and circulatory failure 25.0%(n=129),pneumonia 8. 9%(n =46), cerebral-cardiac syndrome 5. 8%( n =30 ),and multiple organ failure 5. 6%( n =29 ).( 4 ) The mean age of death was 67 ± 12 years old. The patients who died of cerebral hernia and primary central respiratory and circulatory failure were younger than those who died of pneumonia(65 ± 13,68 ± 11,and 75 ± 10,respectively;all P<0. 01). The median length of hospital stay was 3 days. The length of hospital stay in patients who died of hernia,primary central respiratory and circulatory failure,and cerebral-cardiac syndrome were significantly shorter than those who died of pneumonia and multiple organ failure( the median length of hospital stay was 3. 0,3. 0,3. 0,12. 5,and 9. 0 days,respectively;all P <0. 05). Conclusions The mortality of hospitalized patients with cerebral infarction have a declining trend year by year. Brain disease itself is the most important reason of early death for patients with cerebral infarction, indicating that it is the important point of prevention and treatment in clinical work.

Haemophilus influenzae (Hi) is a pathogen exclusively found in humans. It causes a wide range of infections from the upper respiratory tract to serious invasive diseases. Such as pneumonia, septicemia and meningitis. Strains of Hi are usually classif ied into six serotypes a to f and nontypeable H. influenzae (NTHI) according to the antigenicities and compositions of their polysaccharide capsules. Hib was a common cause of serious infections in younger children. The polysaccharide-protein conjugate vaccines against Hib had almost eliminated H. influenzae as a cause of pediatric meningitis. However, NTHI remains an important pathogen, particularly in children and the elderly. Efforts to understand and control NTHI disease have been hampered by the diversity of these bacteria. This review introduced the study progress about pathogenic mechanism of NTHI. In order to provide the help for development of vaccine, clinic treatment and prevent the occurrence of diseases causing by NTHI.

Traditional sequences of magnetic resonance imaging (MRI) such as T1-weighed imaging, T2-weighed imaging, and fluid-attenuated inversion recovery (FLAIR) imaging can sensitively detect the subacute and chronic intracranial hemorrhage; gradient echo sequence can detect various stages of intracranial hemorrhage, but there is no correlation between the signal intensity of the hematoma and the time of the presence of hematoma. Diffusion-weighted imaging and apparent diffusion coefficient may provide more information about the center and surrounding areas of hematoma, as well as the hemorrhagic tendency after infarction.

To study the relationship between the occurrence of pancreatic cancer with diabetes mellitus, other medical conditions and familial history in Chinese population. A case control study comprising 493 histologically confirmed pancreatic cancer patients and 1031 hospital non neoplastic controls matched with age, sex and economical income was conducted. The value of odds ratio (OR) and its 95% confidence interval (CI) to estimate the relative risk of diabetes mellitus, other medical conditions and familial history were calculated. The results showed that ORs and 95%CIs of diabeties diagnosed 2 years prior to the diagnosis of pancreatic cancer, cholelithiasis, chronic pancreatitis, cancer history, pulmonary tuberculosis, Helicobacter pylori infection, family history of cancer and family history of diabetes mellitus were 4 64(2 05～10 49),4 12(2 81～6 04),18 38(6 33～53 35),9 47(4 97～18 06),4 21(2 30～7 72),1 14(0 45～2 89),2 01(1 29～3 14), 0 83(0 15～4 56) respectively. The p values of diabeties and cholelithiasis in logistic regression analysis were less than 0 05. The analysis suggested that diabetes mellitus, cholelithiasis, chronic pancreatitis, cancer history, pulmonary tuberculosis, and family history of cancer were risk factors of pancreatic cancer, whereas diabetes mellitus and cholelithiasis were the independent factors.

Smoking is presently the only generally accepted risk factor for pancreatic cancer. In recent studies, reproductive history has been associated with pancreatic cancer, but with contradictory results. In order to evaluate a possible association between age of first parturition and the number of births and pancreatic cancer, we conducted a case control study with a hospital background. Association between age of first parturition and the number of births and pancreatic cancer was found, and it remained after adjustment for cigarettes smoking, alcohol consumption, body mass index, cholelithiasis, cholecystectomy, diabetes mellitus, chronic pancreatitis and partial gastrectomy. Young age of first parturition and high reproductive history, such as 3 or more births were risk factors for pancreatic cancer.

The study was to analyze the correlation between pancreatic cancer and appendectomy, partial gastrectomy, cholecystectomy and tonsillectomy in Chinese population. Case control study was made comprising 493 pancreatic cancer patients confirmed by histology and 1031 hospitalized non neoplastic controls matched with age, sex, residing district, and economical income. The value of odds ratio (OR) and its 95% confidence interval (CI) were calaclated to estimate the relative risk of appendectomy, partial gastrectomy, cholecystectomy and tonsillectomy to the occurrence of pancreatic cancer, and logistic regression was conducted. The results showed that the risk of pancreatic cancer increased in patients who had had appendectomy, partial gastrectomy and cholecystectomy, and all the p values of trend test were
