It is common in bacterial genomes of the integration of prophages. As an important participant of the vital movement of their hosts, prophages affect closely the biological properties of the hosts. Therefore, if we want to comprehend a bacterial genome fully, it is essential to recognize and understand accurately prophages in it. This article is a compendious review about the classification, distribution, identification, evolution of prophages and the interaction with their hosts.

A flow-injection chemiluminescence ( FI-CL ) reaction system with diperiodatoargentateⅢ was developed for the determination of hydrocortisone in human serum. The weak chemiluminescence signal from the reaction between DPA and sulfuric acid system can be greatly enhanced in the presence of hydrocortisone. The optimal conditions of the CL system were 1. 0 mol/L H2SO4, 2. 5×10-4 mol/L diperiodatoargentateⅢ, and flow rate of 4. 20 mL/min. Under the optimal conditions, the CL intensity was linearly to the concentration of hydrocortisone from 3 . 0 × 10-10 g/mL to 1 . 0 × 10-7 g/mL and the detection limit was 2 . 2 × 10-10 g/mL ( 3σ) . The relative standard deviation ( RSD ) was 0 . 6% ( n =11 ) for 5 . 0 × 10-8 g/mL hydrocortisone solution. The proposed method was successfully applied to the direct determination of hydrocortisone in serum samples with the recoveries of 93 . 0%-110 . 0%, and the relative standard deviations were 0 . 3%-3 . 2%. The possible chemiluminescence mechanism was investigated by measuring fluorescence spectra and UV-vis absorption spectra of the system.

Objective To investigate the effect on the menstrual patterns and sexual quality of life of patients with adenomyosis after treated with Mirena IUD.Methods56 patients with adenomyosis who were treated with Mirena IUD were recruited from August 2009 to December 2009.We used Menstrual blood loss chart method,Dysmenorrhea score method and Brief Index of Sexual Function for Women (BISF-W) to evaluate the menstrual pattern,the volume of uterus and sexual quality after1,3,6,9,12 months.{Results53 patients were followed up,the rate was 94.6%.The condition of 56 patients became better after treated with Mirena for 3,6,9,12 months,dysmenorrhea[Placed before:(3.15±0.91)points;After placing:(1.41±0.51)points,(0.22±0.09)points,(0.07±0.01)points,0 points]and menstrual quantity[Placed before:(12.0±57.5)points;After placing:(71±23.1)points,(29±19.4)points,(18±10.5)points,(10±4.7)points]were both reduced(P＜0.05),the symptoms were not significantly improved after 1 month(P＞0.05).D2 indicators was significantly improved after 3 months of treatment (P＜0.05),sexual function was also improved after 6 months(P＜0.05～0.01).ConclusionsMirena IUD has a good effect on the menstrual pattern and sexual function for patients with adenomyosis.

Bronchiectasis combined with pulmonary carcinoma in situ is very rare condition.This study reported four cases and reviewed some literatures.The data of 66 cases treated from August 2012 to October 2013,whose initial diagnoses as bronchiectases were analysed.Four cases were diagnosed postoperatively as bronchiectasis with pulmonary carcinoma in situ after sugery,accounted for 6％ of surgical patients for bronchiectasis.Bronchiectasis has the risk of combined with pulmonary carcinoma in situ,this should be brought to the attention.

Objective To promote the successful treatments of massive hemoptysis by summarizing the clinical data of 14 patients receiving surgery.Methods 14 cases of massive hemoptysis were retrospectively analysed,Eight male and 6 femal,aged 27-64 (45 ± 18) years including the application of CT,bronchoscopy and extracorporeal membrane oxygenation (ECMO).Results 14 patients received preoerative bronchoscopy and emergency operation.In addition,hymoptysis had not occurred after the surgery in these cases.Conclusion The standardized clinical pathways for massive hemoptysis and the application of preoerative bronchoscopy is essential for emergency treatment of massive hemoptysis.

Through mechanical analisis,it is discovered that the twined structure decides the amplification coefficient of the catgut tension.Many troubles of production can be explained with this mechanics model,and it could be used as a reference for medical sulures. 　　The paper gives an accurate calculating formular for catgut design and its direct tensile strength through improving mechanics model. It can raise the material strength from 10 to over 31% depending on its twined structure.

Objective To perform comparative study on database performance before and after upgrading hardware & software of database. Methods The comparison was carried out from the aspects of hardware expansibility, processing ability, system stability and database performance. Results The reasons for the change of performance and the change law were analyzed. Conclusion After upgrading, the system performance is enhanced greatly.

Objective To investigate the clinical efficacy of acupoint transdermal administered aniemetic herbal plaster combined with intraveous ondansetron preventing chemotheray -induced vomiting .Methods 98 cases of malignant tumor chemotherapy patients were randomly divided into the treatment group of 49 patients and a control group of 49 patients.The treatment group were acupoint transdermal administered animetic herbal plaster combined with intravenous ondansetron while the control group were intravenously administered ondansetron .The clinical effica-cy of preventing chemotheray-induced vomiting was observed .Results The total effective control rate of the treatment group was 93.9% compared with 79.6% of the control group,the efficacy of the treatment group was significantly greater than that in the control group ( P<0.05 ) .Conclusion The antiemetic herbal plaster exhibited significant effect on preventing chemotherapy-induced vomiting after acupoint transdermal application combined with intravenous ondansetron .

Objective To make a concrete analysis of micro-perfusion pump and compatible syringes used in neonatal intensive care unit (NICU) for low birth weight infants,and to find solutions to the defects in application.Methods 20 ml sterile syringes were set different infusion rates (1ml/h,5ml/h,6ml/h,10ml/h),different infusion time (5min,30min,lh).Then,the card slot on the micro-perfusion pump where the end of 20ml sterile syringe was placed was regulated.The regulated syringes were also set different infusion rates (5ml/h,6ml/h,l0ml/h) and time as before.The error accuracy was calculated.Results The results showed that at the end stage of 20ml sterile syringes pumping,there was always 0.5～1.5 ml residual liquid which could not be pumped out,but perfusion pump displayed injection was completed.Before regulation,the error accuracy between different infusion rates of 20ml sterile syringes was 6.00％,3.80％,2.33％,1.30％ respectively.However,after improvement,the regulated syringes could completely pump all liquid out,and the error accuracy between different infusion rates and different infusion time was also superior to pre-improvement.Conclusions Improved micro-infusion pump and sterile solution prefilled syringe have no drug residual,and display high accuracy and small error accuracy.
