Objective To compare the two kinds of the single nostril transsphenoidal approach of minimally invasive surgery of pituitary adenoma and analyze the clinical data ,and then provide references for clinical diagnosis and treatment .Methods The prospective study methods were used in the study .A total of 54 cases of pituitary tumor patients were collected , they were randomly divided into microscope group ( 31 cases ) and neural endoscopic group (23 cases).The operation time,intraoperative blood loss,hospital stay,the resection rate,postoperative complications ( mainly observed transient postoperative insipidus and transient electrolyte disorder ) , the hormone levels , and the comparison the results of patients ,follow-up within 1 year were observed .Results The operation time of microscope group(121.3+19.4)min was longer than that of the neuroendoscopic group (78.5 ±7.8)ml,but the intraoperative blood loss in the microscope group was less than that of the neuroendoscopic group [(50.3 ±3.2) mL vs (78.5 ± 7.8)mL,t=0.993,1.032,all P>0.05].The postoperative hospital stay [(8.7 +1.1) d vs (9.1 +2.3) d,t=2.897,P>0.05],the resection rate(93.5% vs 91.3%,χ2 =3.191,P>0.05) had no significant differences be-tween the two groups .The postoperative complications ( including transient insipidus and transient electrolyte disorder ) also had no obvious differences .The analysis of the endocrine hormone levels of different tumors found that there were no significant differences between the microscope group and neuroendoscopic group .The levels of these pre operative and postoperative hormones were as follows:PRL[(387.3 ±100.8)μg/L vs (145.3 ±27.4)μg/L and (390.2 ± 133.7)μg/L vs (148.4 ±57.2)μg/L],GH[(63.4 ±5.7)μg/L vs (10.6 ±2.4)μg/L and (65.6 ±6.2)μg/L vs (12.4 ±1.6)μg/L],ACTH[(202.9 ±73.7)ng/L vs (38.5 ±4.6)ng/L and (206.8 ±78.6)ng/L vs (35.6 ± 2.5)ng/L],they all had significant differences (t =1.456,1.301,0.973,1.034,0.774,0,732,all P <0.05). Conclusion The curative effects of the two surgical treatment of pituitary adenoma have no obvious differences ,they have advantages of minimally invasive , safe and effective, but the microscopic surgery has less bleeding , while neuroendoscopic surgery can shorten the operation time .

Objective To study the protective mechanism of mild hypothermia from severe traumatic brain injury (sTBI). Methods 160 cases with sTBI were treated under normothermia (NT group, n=80) and mild hypothermia (HT group, n=80) respectively. Their serum level of anti-brain antibody (ABAb) was measured with ELISA, cerebral haemodynamics with transcranial Doppler, and intracranial pressure (ICP) with ICP monitor 1 d, 3 d, 5 d, 7 d and 14 d after injury, while they were assessed with Glasgow coma scale (GCS) and Glasgow outcome scale (GOS). Results The level of ABAb was lower in HT group than in NT group (P<0.05) at every point. The scores of GCS increased (P<0.05), and the volume of systole, mean and pulse index improved more in HT group 5 d after injury (P<0.01). The ICP was lower in HT group 3 d after injury (P<0.01). The score of GOS was better in HT group than in NT group when discharged (P<0.05). Conclusion Mild hypothermia can reduce the level of serum anti-brain antibody, improve cerebral haemodynamics, decrease ICP and improve the prognosis in patients with sTBl.

Objective To explore changes of risk factors between premenopausal and postmenopausal female patients with coronary heart disease (CHD). Methods A total of 283 female patients were divided into CHD group (n=154) and con?trol group (n=129) according to whether they suffered from CHD or not. Patients were further stratified into two groups accord?ing to menopausal situation:premenopausal group (n=78, including premenopausal CHD group of 34 cases and premenopaus?al control group of 44 cases) and postmenopausal group (n=205, including postmenopausal CHD group of 120 cases and post?menopausal control group of 85 cases). Clinical data of age, body mass index (BMI), medical history and menses situation were recorded. The levels of cholesterol (CHO), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), low density lipo?protein cholesterol (LDL-C), very low density lipoprotein cholesterol (vLDL-C), apolipoprotein AI (ApoAI), apolipoprotein B (apoB), lipoprotein a (Lpa), homocysteine (HCY) and high-sensitive C-reactive protein (hsCRP) were also detected. Results There were significantly higher levels of age, CHO, TG, LDL-C, vLDL-C, Lpa, ApoB, hsCRP, and the ratio of hypertension history, diabetic history, coronary heart disease family history in CHD group than those of control group. The level of HDLc was significantly lower in CHD group than that of control group. The ratio of hypertension history, diabetic history and levels of CHO, TG, LDL-C, vLDL-C, Lpa, ApoB, hsCRP were significantly higher in both premenopausal and postmenopausal CHD groups than those of their control groups. The level of HDL-C was significantly lower in postmenopausal CHD group than that of postmenopausal control group (P<0.05). Hypertension history, diabetic history and LDL-C were the independent risk fac?tors of premenopausal CHD. Hypertension history, diabetic history and CHO were the independent risk factors of postmeno?pausal CHD, and HDL-C was the protecting factor of CHD. The ratio of hypertension history, the level of CHO and LDL-C were significantly higher in postmenopausal CHD group than those of premonopausal CHD group. Conclusion The abnor?mal blood pressure level and dyslipidemia are more prevalent in postmenopausal female patients with CHD than premeno?pausal female patients. We should control these risk factors to improve the prognosis.

The study aimed at investigation the effect of the transgenic biocontrol bacteria 308R(pCPP430) on the tomato rhizosphere bacterial communities. Strain 308R (Pantoea agglomerans), an adnascent bacterium isolated from tomato, was a biocontrol bacterium. The recombinant cosmid pCPP430 contained the hrp gene cluster of Erwinia amylovora was transformed into 308R Strain. Transgenic biocontrol bacterium 308R(pCPP430) produced Harpin protein which induce hypersensitive response and disease resistance in plants and, surprisingly, increase plant growth. Two complementary methods, sole-carbon-source utilization tests (SCSU) and ERIC-PCR, were used to compare the characterization of bacterial communities from three groups of tomato roots dipped in sterilized water, 308R suspended liquid and 308R(pCPP430) suspended liquid. The cluster analysis and principal components analysis of the number of colonies from SCSU indicated consistent differences in the rhizosphere of each group. Cluster analysis of SCSU data showed that there were consistent differences in the rhizosphere of each group. The rhizosphere bacteria communities of root dipped with 308R(pCPP 430) and 308R have a relative good replication, but the differences of corresponding replicates in dipped with distilled water was increased by degrees. Cluster analysis of ERIC-PCR fingerprints revealed that most of results (eight in ten) have overlaps between roots dipped in water and those dipped in 308R liquid. The methods used in this study may prove a useful approach for the comparison of bacterial communities.
