The use of optimal regulatory sequences for simultaneous expression of the transgenes might play a significant role in engineering plants with increased disease and insect resistance.The plant expression vector pOMS-GUS,which contained the GUS gene under the control of a chimeric promoter based upon the mannopine synthase(mas)promoter and the octopine synthase(ocs)enhancer,was constructed.Used as control,another vector pMAS-GUS,carried the GUS gene driven by only the mas promoter.The two vectors were introduced into tobacco plants by Agrobacterium-mediated transformation.Fluorometric assays for GUS activity and reverse transcription-polymerase chain reaction(RT-PCR)analysis revealed that GUS gene expressed weakly with untreated transgenic tobacco while the level of GUS activity increased steadily after 1 h subjected to wounding.The expression of the mas and ocs/mas promoters was induced a further 1.8-fold and 5.7-fold,respectively.SA(1 mmol/L)or MJ(250 ?mol/L)treatment also caused a large induction of the ocs/mas chimeric promoter;And the application of SA in combination with MJ(1 mmol/LSA & 250 ?mol/L MJ)produced an additive effect that exceeded the wounding response.The results showed that the ocs/mas chimeric promoter is a strong inducible promoter that can be activated by various stresses.The chimeric promoter should have utility in development of disease and insect resistant transgenic crops.

Objective To improve the utilization ratio of operating room in Affiliated Hospital of Central South Uni-versity Xiangya Medical School by providing more comprehensive reference data for the design of surgical time pre-diction and dispatch system. Methods A questionnaire was designed according to the review of literature and consul-tation of experts for investigating the surgical time influencing factors. The surgical time influencing factors were ana-lyzed by stratified sampling. Results The surgeons-related factor was the highest influencing factor while the pa-tients themselves-related factor was the lowest influencing factor in the 2-dimensional factors. The selected 38 1-dimensional factors could affect the operating time with their mean influencing value>2 . 45 . The recognition of sur-gical time influencing factors was different in different operating rooms. Conclusion There are a variety of surgical time influencing factors. However, the surgeons-related factor is the highest influencing factor. The cognition of anesthesia-related factors and surgeons-related factors differs in different operating rooms.

Objective To explore the value of temporary cardiac pacemaker therapy on children with Adam-Stoke syndrome(ASS).Methods Nine children with ASS was implanted the emporary cardiac pacemaker under X-ray or blinding inserted beside bed.Results Seven children was successfully implanted the temporary cardiac pacemaker within 1-2 d of ASS attack,and two children was successfully implanted at 10 d and 20 d after ASS attack, respectively. Five patients was cured, two children was died, and two children was implanted the permanent cardiac pacemaker. During pacing, two patients had the electrode shifted,and one patient had the cardiac murmur,and one patient had the local skin infected.Conclusion Temporary cardiac pacemaker can successfully treat children with ASS attack;the earlier the implantation,the better the prognosis.

Objective To explore the prognosis and etiological treatment of cardiogenic syncope in children.Methods The cause,clinical manifestation,treatment and prognosis of 45 children with syncope were made in affiliated hospital of Qingdao medical university were su mmarized and analyzed.They were divided into arhythmia group and other groups,the former included myocarditis,dilated cardiomyopathy,and post-operation of congenital heart disease and the latter included tetralogy of fallot,pulmonary stenosis,hypertrophic cardiomyopathy,pericarclial effusion,and right atrial myxoma.Results There were 29 cases(64.44%) with arrhythmia in this group,of which there were 18 cases with complete atrioventricular block(CAVB),2 cases with second degree type Ⅱ atrioventricular block,3 cases with ventricular tachycardia,2 cases with bradycardia,2 cases with atrial flutter,1 case with supraventricular tachycardia,and 1 case with nonconducting atrial premature.There were 16 cases(35.56%) with other etiologies,of which there 8 cases with tetralogy of Fallot,2 cases with pulmonary stenosis,hypertrop-hic cardiomyopathy,pericardial effusion,and right atrial myxoma,respectively.Children with CAVB,bradycardia,or ventricular tachycardia resulted from viral myocarditis were given anti-virus medicine,protecting myocardium,neoepinephrine,and intravenous vitamin C 100-200 mg/(kg?d).Dexamethasone 1-2 mg/(kg?d) was given in earlier period for short course,and some children were given human ?-globulin.Eight cases were placed temporary pacemaker because of unsatisfactory therapeutic efficacy,and 1 case was placed permanent pacemaker.In all,38 cases(84.44%)were cured,1 case(2.22%)was improved,and 4 cases(8.88%) died.Conclusions Cardiogenic syncope is pediatric emergency and shall be treated immediately.Temporary pacemaker shall be placed at the right moment.

Objective To explore the clinical characteristics, surgical treatment and related factors of traumatic implantation cyst of the iris. Design Retrospective cases series. Participants Thirty-six cases of traumatic implantation cyst of the iris. Methods Thir- ty-six cases of traumatic implantation cyst of the iris were reviewed. Main Outcome Measures Age, surgical history, history of disease, surgical method of patients. Results All cases of traumatic implantation cyst of the iris were secondary to perforating injury. 10 cases had been undertaken cataract surgery. The histories of disease in 6 months～1 year and 1 year～10 years were 30.56% respectively. Sur- gical exicision was taken in all cases. There were 2 recurrence cases. Conclusion Traumatic implantation cyst of the iris is almost see- ondary to perforating injury. Surgical excision is an effective strategy to treat this disease.

OBJECTIVETo investigate the tongue manifestation features of sexually transmitted and intravenous drug use spread HIV infected population in Xinjiang.

METHODSRecruited were 990 HIV infected subjects in Xinjiang from May 2011 to March 2012, who were assigned to the intravenous drug use spread HIV infected (498 cases) and the sexually transmitted (492 cases). By using tongue figure shoot combined with analyses of experts, tongue manifestations were analyzed and compared between the sexually transmitted and the intravenous drug use spread from four aspects, i.e., the tongue color, the tongue shape, the fur color, and the fur property.

RESULTSCompared with the sexually transmitted population, red tongue, fissured tongue, yellow fur, thick fur, eroded fur, deficiency of fur fluid were more often seen, showing statistical difference (P < 0.05). Compared with the intravenous drug use spread population, pale tongue, white fur, and thin fur were more often seen, showing statistical difference (P < 0.05).

CONCLUSIONSThe tongue manifestations of the intravenous drug use spread HIV population reflected inner exuberance of evil toxin and heat impairing qi and yin. Compared with the intravenous drug use spread population, the attack of HIV infection was more hiding in the sexually transmitted population, with milder internal injury. Their Wei-qi was not damaged and no obvious change occurred in the tongue figure.

OBJECTIVETo observe the analgesic effect and safety of acupuncture-anesthetic composite anesthesia (AACA) in hysteroscopic surgery.

METHODSTotally 93 patients undergoing hysteroscopic surgery were randomly assigned to the intravenous anesthesia group (A group, 30 cases), the AACA group (B group, 32 cases), and the acupuncture combined with intravenous anesthesia group (C group, 31 cases). Patients in Group A were anesthetized by sufentanil combined propofol. Those in Group B were anesthetized by sufentanil combined acupuncture. Those in Group C were anesthetized by sufentanil, propofol combined acupuncture. Yinlian and Ququan (LR8) were needled for patients in Group B and C. The peri-operative mean arterial pressure (MAP), heart rate (HR), and oxygen saturation (SpO2), the surgical time, the recovery time, the sufentanil and propofol dosages, adverse anesthesia reactions were observed. Meanwhile, the OAA/S score, Ramsay sedation score, and Visual Analogue Score (VAS) were also measured.

RESULTSCompared with Group A and C, patients in Group B were awake, with obvious increased OAA/S score (P < 0.01). Ramsay sedation score was significantly lower (P < 0.01).The MAP and HR were elevated (P < 0.05). The patient case of SpO2 less than 85% during the operation decreased (P < 0.05). The incidence of postoperative dizziness was reduced (P < 0.05). Compared with Group A, the propofol consumption decreased in Group C (P < 0.05). There was no statistical difference in the operation time, the sufentanil dosage, VAS score, the incidence of postoperative nause- a and vomiting among the three groups (P > 0.05).

CONCLUSIONSThe patients were awake in AACA. The intraoperative sedation was better than that obtained by intravenous anesthesia. But the analgesic effect was similar to that obtained by intravenous anesthesia.

To analysis the differences between Tripterygium wilfordii and T. hypoglaucum, specimens of their leaves were collected from five production regions and analyzed by ultra performance liquid chromatography coupled with quadrupole time of flight mass spectrometry (UPLC-Q-TOF-MS). The data were analyzed by multivariate statistical method, such as hierarchical cluster analysis (HCA) principal component analysis (PCA) and orthogonal signal correction partial least square discrimination (OPLS-DA). Potential markers with VIP values above 5.0 and corresponding r values above 0.85, were selected and further tested by combining mann-Whitney nonparametric. Those with P < 0.001 and AUC = 1 were confirmed as metabolite markers to discriminate them from each other. Results revealed that the two species were obviously different in their leaf metabolites. Based on their mass spectra, 23 potential metabolite markers were identified to distinguish T. wilfordii from T. hypoglaucum.
