1.Fecal Microbiota Transplantation and Inflammatory Bowel Disease
Chinese Journal of Gastroenterology 2016;21(8):491-493
Inflammatory bowel disease( IBD),comprising Crohn’s disease( CD)and ulcerative colitis( UC),is a chronic intestinal inflammatory disease and its etiology has not yet been clarified. Studies showed that intestinal microbiota disorder is closely associated with the development and progression of IBD. Currently,fecal microbiota transplantation (FMT)is considered as a special organ transplantation and used in treatment of IBD,Clostridium difficile infection, irritable bowel syndrome,metabolic syndrome,etc. This article reviewed the relationship between FMT and IBD.

Chinese Journal of Practical Nursing 2010;26(10):13-15
Objective To investigate effective methods for preventing radiotherapy - induced oral mucositis among patients with cephalocervical malignant tumors. Methods 92 patients with cephalocer-vical malignant tumors treated with radiotherapy were randomly divided into group A (31 cases),group B (31 cases) and group C (30 cases). Mixture of 20 ml heartleaf houttuynia herb injection,20 ml salvia injection and 30 ml distilled water were given to patients in group A by means of nebulization inhalation one hour before and after every radiotherapy treatment, the inhalation lasted 20 minutes each time up to the end of radiotherapy. Mixture of 2 ml Kang-fu-xin injection,0.5 mg vitamin B|2 injection and SO ml normal saline were given to patients in group B by the same means as group A. Yangyin Qingfei decoction were given to patients in group C by means of selecting its 500 ml juice for oral use. Half of the 500 ml decoction were separately given 1 hour before and after each radiotherapy treatment up to the end of radiotherapy. Results The incidence rates of oral mucositis were obviously lower among patients in group A than in group B and C. Conclusions Nebulization inhalation of mixture of heartleaf houttuynia herb and salvia injections has significant clinical effects on oral mucositis after radiotherapy.

OBJECTIVE:To analyse the advantages and disvantages of split tablets given to in-patients.METHODS:We collected13kinds of oral tablets(10tablets each kind and260pieces of the split tablet altogether),which were often splitted by pharmaceutists.We tested and analysed the weight variation of the split tablet on the basis of the dosage consistency metioned in the USP which is applied to the whole tablet.RESULTS:None of the13kinds of prescription drug passed the consistent testing after splitting.There was some relationship between the effect of the split tablet and its shape.It was relatively easy to break off the tablet with nick in half.The loss of dosage inevitably occurred during the process of splitting the tablet.CONCLUSION:Breaking off the tablet in half led to high ratio of weight variation.The modus operandi of splitting the tablet in half for saving expenses can only be applied to those drugs with low toxicities and relatively flat dose-effect curve.In the case of those drugs which bear high toxicities and steep dose-effect curve,carefulness should always be taken when applying such method.

Aim To develop a sensitive, rapid and ac-curate LC-MSn method for determination of midazolam/1′-hydroxymidazolam and their pharmacokinetic char-acteristics in rat brain. Methods SD rats received in-travenous injection of midazolam ( 5 mg · kg-1 ) via femoral vein, a probe drug of cytochrome P450 3A. The microdialysis ( MD ) samples in situ brain were collected every 8 mins at 2. 0μl·min-1 in 2. 4 hours. Analytes in brain dialysate were quantified by the pro-posed LC-MSn method. Gradient elution was performed on an Agilent Eclipse Plus-C18 column ( 2 . 1 × 50 mm, 3. 5 μm). The mobile phase consisted of 2 mmol ·L-1 ammonium acetate and acetonitrile. The analyte was detected using electrospray ionization ( ESI ) in multiple reaction monitoring ( MRM) modes. The reac-tion selected ions were 326 . 1/291 . 1 m/z for midazo-lam, 342. 1/324. 1 m/z for 1′-hydroxymidazolam and 285. 1/154. 0 m/z for diazepam as internal standard. Result The linear ranges of midazolam and 1′-hydroxymidazolam were 0 . 78~100 and 0 . 195 ~12 . 5μg·L-1 respectively. The lower limit of quantification was 0 . 2 μg · L-1 . The RSD of intra- and inter-batch precisions was less than 7 %. The RSD of accuracy was from -1 . 34 to -8 %. Conclusion This sensi-tive and rapid LC-MSn method is suitable for determi-nation of midazolam/1′-hydroxymidazolam in rat brain dialysate. MD combined with LC-MSn method may give assistance to deep and further studies of drug metabo-lism and CYP3A enzyme in brain.

Objective By studying the expressions of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) in rats′ cardiac muscle after acute myocardial infarction, we try to find out the relation between the expression of these two factors and the formation of new blood vessels under ischemia. Methods Wistar rats were divided into control group and infarction group (3, 7, 14, 28, 42, 56 d). The expression of VEGF and bFGF in cardiac muscle and endothelial cells is detected by means of immunohisto-chemial staining while the density of newly formed ressels is detected by marking the endothelial cells with antigens associated with factor Ⅷ. Results After ligating the left anterior descending coronary artery of the rats, the expression of VEGF and bFGF increased along with the prolongation of myocardial ischemia and reached the peak on the 7th day. The expression of the 2 factors began to decrease on the 28th day and the most significant decrease happened on the 42th and 56th day. The density of the newly formed capillaries is directly propontimal to the levels of the 2 factors. Less expression of VEGF and bFGF was observed in the control group. Conclusion The up-regulation of VEGF and bFGF expression might play important roles in neovascularization. Dicrectly intramyocardial injection of bFGF and VEGF gene at the time when the expression of bFGF and VEGF began to decrease maybe optimal.

Objective To evaluate the efficacy of the continuation of cardiopulmonary resuscitation (CPR) following transportation to the emergency department in a Chinese hospital after unsuccessful emergency medical services (EMS) CPR. Methods From January 2002 to December 2007, emergency records of non-traumatic patients who were transported to a tertiary teaching hospital after unsuccessful EMS CPR were reviewed. Results Eigty-five patients were included, and 13 patients (15%) accomplished restoration of spontaneous circulation in our emergency department. Resuscitative possibility reached zero at around 23 minutes. One patient was discharged with a favourable neurologic outcome. Conclusions This study shows that the continuation of CPR is not futile and may improve outcomes. The outcomes should be re-evaluatad in the future when prehospital information can be combined with in-hospital information.

Objective To investigate the influence of central aortic pressure and pulse pressure in coronary Artery. Methods The research involed 173 patients who were suspected coronary heart disease (CHD) in the Fifth People′s Hospital of Chengdu city. The patients were divided into non-coronary disease and coronary disease groups. Patients were divided into one- vessel, two- vessels and three-vessels in coronary disease groups. The data were analyzed by using spass 17.0 software. Results SBP-C,DBP-C and PP-C had statistical significance compared with non-coronary disease (P < 0.05).SBP-C and PP-C had significant difference between single-branch and multiple-branch group(P < 0.05).Logistic multivariate analysis indicated that SBP-C [P = 0.019,OR = 1.207, 95%CI(1.032,1.412)]and PP-C [P = 0.023, OR = 1.166,95%CI (1.021,1.332)] had significant correlation. Conclusion Compared with non-coronary, SBP-C and PP-C were higher, while DBP-C was lower. The higher SBP-C and PP-C are,the worse coronary artery is. SBP-C and PP-C are predispose risk factors for multiple-vessels coronary disease.
