ABSTRACT

Galactinol synthase (GolS) genes play important roles in plant response to abiotic stress. In this research, the plant expression vector of soybean GmGolS2-2 gene was constructed and transformed into tobacco to study the drought tolerance of transgenic tobacco. A GmGolS2-2 gene with 975 bp coding sequence was cloned from soybean leaves by reverse transcription-polymerase chain reaction (RT-PCR). GmGolS2-2 was linked to the plant expression vector pRI101 by restriction enzyme sites Nde Ⅰ and EcoR Ⅰ, and transformed into tobacco by leaf disc method. Genomic DNA PCR and real-time PCR showed that three GmGolS2-2 transgenic tobacco plants were obtained. The growth status of GmGolS2-2 transgenic tobacco under drought stress was better than that of wild-type tobacco. After drought stress treatment, the electrolyte leakage and malondialdehyde content of transgenic tobacco were lower than those of wild-type tobacco, but the proline content and soluble sugar content were higher than those of wild-type tobacco. The results of real-time PCR showed that the heterologous expression of GmGolS2-2 increased the expression of stress-related genes NtERD10C and NtAQP1 in transgenic tobacco. The above results indicated that GmGolS2-2 improved drought resistance of transgenic tobacco.

ABSTRACT

OBJECTIVE:To evaluate the effect of clinical pharmacists participating in chronic disease management for chronic heart failure (CHF)patients. METHODS :Totally 160 patients with CHF in our h ospital from Jan. 2016 to Dec. 2017 were divided into intervention group (80 cases)and control group (80 cases)according to random number table method. The patients received CHF routine examination and drug treatment at admission ;on this basis ,the patients in the intervention group received clinical pharmacist chronic disease management as inpatient pharmaceutical care ,medication education at discharge and pharamceutical follow-up at discharge. The cardiac function indexes (NYHA cardiac function classification ,LVEF,NT-proBNP,LVDd), comprehensive self-care ability (scores of self-care ability ,drug compliance ,understanding of disease-related knowledge ,and total score of comprehensive self-care ability ),and life quality (emotional score ,symptom score ,social restriction score ,and total score of life quality )at admission ,discharge and 6 months after discharge ;economic indicators (total hospitalization expenses , hospitalization time ,drug expenses and drug proportion )during hospitalization ;readmission and case fatality within 6 months after discharge were compared between the two groups. RESULTS :At admission ,there was no significant difference in the above indicators between 2 groups(P>0.05);at discharge ,except for LVEF ,emotional score and social restriction score ,the other indicators in 2 groups were significantly improved ,compared with at admission (P<0.05);six months after discharge ,the above indicators of 2 groups were significantly improved compared with at admission ,and LVEF ,LVDd,drug compliance score ,score of understanding of disease-related knowledge ,total score of comprehensive self-care ability ,emotion score ,symptom score ,total score of life quality in the intervention group were significantly better than control group (P<0.05). There was no significant difference in the total hospitalization expenses ,hospitalization time ,drug expenses and drug proportion between 2 groups(P> 0.05). Within 6 months after discharge ,the readmission rate of the intervention group was 14.29%,which was significantly lower than that(29.33%)of control group (P<0.05). There was no significant difference in case fatality rate between 2 groups(P> 0.05). CONCLUSIONS :The participation of clinical pharmacists in chronic disease management of CHF patients can significantly improve the cardiac function indexes ,comprehensive self-care ability and quality of life ,and reduce the readmission rate.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the result of colorectal cancer screening for high-risk groups in Harbin, China from 2012 to 2015.</p><p><b>METHODS</b>According to the Project of National Colorectal Cancer Screening in Urban Area, epidemiological investigation and cancer risk evaluation established by National Cancer Center were performed among 40-69 years old residents in Harbin. Questionnaires were issued to assess high-risk groups for clinical screening, including colonoscope examination. The results of colorectal screening were evaluated in detail.</p><p><b>RESULTS</b>Project of Colorectal Cancer Screening in Urban Area was completed successfully from 2012 to 2015 in various districts of Harbin. The accomplishment of high-risk assessment included 3 017 people, while 2 996 people received the clinical screening, including 1 376 males and 1 629 females, from 40 to 69 (53.3±7.1) years old. Among 2 996 people, 1 158 cases of colorectal polyps(38.7%) were screened, including 36.6%(901/2 465) cases of age<60 and 48.4%(257/531) cases of age>60 years old with significant difference (χ=19.19, P<0.01), and 47.6% (651/1 367) cases of male and 31.1%(507/1 629) cases of female with significant difference (χ=85.33, P<0.01). Of 1 158 polyps patients, 141 received the pathological examination and 11 patients were diagnosed as colorectal cancer, accounting for 0.4% of overall screening people (11/2 996). All these 11 patients underwent operation by advice and the postoperative pathology results all indicated early adenocarcinoma. Furthermore, among 141 polyps patients, 97 cases of tubular adenoma were found, which were distributed as follows: 2 cases of cecum (2.1%), 14 cases of ascending colon(14.4%), 12 cases of transverse colon (12.4%), 15 cases of descending colon (15.5%), 35 cases of sigmoid colon (36.1%) and 19 cases of rectum(19.6%).</p><p><b>CONCLUSION</b>With the increase in age, the risk of colorectal polyps is significantly elevated. The males have higher incidence of colorectal polyps than the females. Adenoma mainly locates in the distal colon and rectum, especially in the sigmoid colon. Early screening for high-risk group can find out colorectal precancerosis and cancer, so the patients can receive early treatment.</p>

ABSTRACT

Objective To investigate Danhong in improving the movement function of reperfused rat after stroke. Methods Rats to make middle cerebral artery occlusion model,after 24 hours of reperfusion were divided into control group,high dose and low dose of Danhong groups and Venorruton group randomly. Rats in Control group were injected saline. High and low dose group were injected DanHong according to their weight,high dose as 14. 4 mg/kg,low dose as 3. 6 mg/kg. Venorruton group were injected Venorruton as 0. 04 g/kg. The infarcted square of rat brain was measured,the rats were tested with walking wood bar and two fore limb grasp strength. Results Rat infarcted squre in 24 hours and 3 days,control groups is the biggest,compared with others,there are statistically difference(P<0. 05). Score in each group of walking wood bar in 3rd days are (1. 30 ± 0. 91),(3. 78 ± 1. 72),(4. 18 ± 2. 05),(4. 63 ± 2. 45). Compared between control and other druge groups,there are statistically differnec(P<0. 05). There are statistically differences between control and other groups in two fore limb grasp testing(P<0. 05). Conclusion Danhong has the same effect which can improve the movement function to stroke rat as Venorruton.

ABSTRACT

Objective To study the rehabilitation effect of Bellidifolin for injuried sciatic nerve,and to explore whether ciliary neurotro-phic factor ( CNTF) is involved in this mechanism. Methods The right sciatic nerver of 225 male wistar rats was cut and sewed under mi-croscopy. Rats were devided into 5 groups,as control group,Bellidifolin 25 mg group,50 mg group、75 mg group and Mecobalamin group. The control group were injected sodium chloride,other groups were injected different dose of Bellidifolin and Mecobalamin. 1,3 and 5 weeks later, the motor nerve conduction velocity( MNVC) and gastrocnemius muscle cross-sectional area were detected,CNTF positive area were analysed by immunohistochemical method. Results There were differences among bellidifolin groups,control group and mecobalamin group in Nerve conduction velocity. Within Bellidifolin groups,50 mg group compared with 25 mg and 75 mg groups,there were statistically differences( P=0. 025). Three weeks after operation,gastrocnemius muscle cross-sectional area of control group,mecobalaming grop and Bellidifolin 25 mg group,50 mg group,and 75 mg group were(455. 06 ± 29. 38),(679. 03 ± 81. 48),(465. 31 ± 71. 55),(670. 24 ± 91. 26) and (669. 28 ± 78. 54) respectively,compared with control group and Bellidifolin 25 mg group,others had a significant difference(P<0. 05). CNTF expres-sion showed billidifolin 50 mg group are higher than others(P<0. 05). Conclusion Bellidifolin can improve the rehabilitation of injured sciatic nerve. CNTF is involved in this mechnism.
