Objective To learn the correlation between thyroid function and arteriosclerosis in elderly popu-lation,and to provide research data for early clinical intervention.Methods 7 1 elderly patients with hypothyroidism were selected as A group,76 elderly patients with subclinical hypothyroidism were selected as B group,70 healthy elderly cases were selected as C group.Triiodothyronine (FT3 ),tetraiodothyronine (FT4 ),thyrotrophin (TSH ), triglyceride (TG),total cholesterol (TC ),low density lipoprotein cholesterol (LDL -C ),high density lipoprotein cholesterol (HDL-C),C reactive protein (CRP)levels of the three groups were detected.Carotid artery intima media thickness (CIMT)was examined by color Doppler ultrasonography.Results FT4 levels of A group,B group were (5.25 ±4.17)pmol/L,(10.74 ±5.02)pmol/L respectively,which were lower than (18.53 ±6.38)pmol/L of C group.TSH levels of A group,B group were (16.45 ±6.96)mU/L,(6.25 ±3.84)mU/L respectively,which were higher than (3.37 ±1.13)mU/L of C group (t=14.650,8.232,15.522,6.037,all P<0.05).FT4 level of A group was lower than that of B group,TSH level of A group was higher than B group (t=7.185,11.097,P<0.05).TC, LDL-C levels of A group,B group were (5.96 ±1.01)mmol/L,(4.15 ±1.69)mmol/L,(5.64 ±0.94)mmol/L, (3.64 ±1.17)mmol/L respectively,which were higher than those of C group [(5.17 ±1.12)mmol/L,(3.20 ± 1.06)mmol/L](t=4.400,2.754,3.992,2.374,all P<0.05).TC,LDL-C levels of A group were higher than B group (t=1.990,2.139,all P<0.05).CIMT,CRP levels of A group,B group were (0.90 ±0.23)mm,(6.20 ± 1.31)mg/L,(0.79 ±0.17)mm,(4.55 ±1.05)mg/L respectively,which were higher than those of C group [(0.68 ±0.11)mm,(3.12 ±0.88)mg/L](t=7.229,4.599,16.364,8.878,all P<0.05).CIMT,CRP levels of A group were higher than B group (t=3.312,8.453,all P<0.05 ).CIMT and TSH,LDL -C,CRP levels were positively correlated (r=0.789,0.647,0.583,all P<0.05),CIMT and FT4 levels were negatively correlated (r=-0.636,P<0.05 ).Conclusion Hypothyroidism,subclinical hypothyroidism are associated with atherosclerosis in elderly population,and elderly patients with hypothyroidism,subclinical hypothyroidism are at high risk of atherosclerosis.

Objective To compare the therapeutic effect of routine dose of calcitriol and large dose impulsion therapy on hemodialysis patients with secondary hyperparathyroidism(SHPT). Methods 48 uremic hemodialysis patients were divided into group A(routine group, n = 22) and group B(control group, n = 21 ). In group A,22 pa-tients were administered with calcitriol for 6 months at the dosage of 0.25～0.5μg/d,adding calcium agents simul-taneously;the patients in group B were not given calcitriol for economic reason. In group C,21 patients were given calcitriol twice a week at the dosage of 2μg/time after hemodialysis for 3 months. Results Comparing to group B,serum PTH,AKP in group A had no significant difference,but serum hypocalcium and hyperphasphate were partly corrected,symptoms of bone pain, muscular convulsion and akin pruriter were improved. Comparing to group A,serum hypocalcium and hyperphasphate in group C were corrected, serum PTH, AKP were significantly decreased( t=2.031,P<0.05;t =3.317,P<0.001),and no hypercalcium oecurred. Conelosion Routine dose of calcitriol can not control uremic-SHirr,while impulsion therapy with lower dose oral calcitriol is effective and safe.

ObjectiveTo analyze the influence of different anesthesia methods on the stress response and hemodynamic of elderly patients undergoing laparoscopic cholecystectomy(LC).Methods Fifty-eight elderly patients who needed LC were selected and divided by random digits table method into GAEA group received general anesthesia combined with epidural anesthesia and GA group received general anesthesia with 29 cases each.The stress response and changes of hemodynamic were observed.Results Blood pressure and heart rate (HR) were elevated during pneumoperitoneum in both groups.Blood pressure and HR returned to normal at 30 minutes after pneumoperitoneum in GAEA group,which were recovered more slowly in GA group.There was no significant difference in systolic blood pressure (SBP),diastolic blood pressure (DBP),HR between two groups before and after anesthesia (P＞0.05).SBP,DBP,HR of GAEA group were ( 123.8 ± 25.9) mm Hg ( 1 mm Hg =0.133 kPa),(85.9 ± 8.4) mm Hg,(83.2 ± 7.4) times/min during pneumoperitoneum,respectively,(118.2 ±21.1) mm Hg,(84.4 ±8.3) mm Hg,(82.8 ±7.5)times/min at 10 min after pneumoperitoneum,( 114.9 ± 20.7) mm Hg,(80.2 ± 7.6) mm Hg,(78.5 ± 10.4)times/min at 30 min after pneumoperitoneum.SBP,DBP,HR of GA group were (138.3 ±26.7) mm Hg,(91.2 ± 8.8) mm Hg,(89.3 ± 10.1 ) times/min during pneumoperitoneum,( 130.3 ± 21.3) mm Hg,(89.2 ±8.6) mm Hg,(88.2 ± 9.7) times/min at 10 min after pneumoperitoneum,( 126.2 ± 20.7) mm Hg,(85.2 ±8.4) mm Hg,(84.9 ± 9.6 ) times/min at 30 min after pneumoperitoneum,respectively.SBP,DBP,HR during pneumoperitoneum,at 10 min and 30 min after pneumoperitoneum in two groups had significant differences (P ＜0.05).The anesthesia onset time in GAEA group was(73.2 ±24.9) s,and the awake time after operation was (31.6 ± 10.2) min,while those in GA group were (78.1 ± 22.4) s and (35.9 ± 14.3) min.The anesthesia onset time and awake time after operation in GAEA group were shorter than those in GA group,but had no significant difference (P＞ 0.05 ).Postoperative visual analogue score of GAEA group [ ( 13.4 ± 8.2)scores] was obviously lower than that of GA group[(26.3 ± 10.1) scores] (P ＜0.05).The incidence of adverse reactions between GAEA group [27.59％(8/29)] and GA group [6.90％(2/29)] had statistical difference (P ＜ 0.05).ConclusionsCompared with general anesthesia,general anesthesia combined with epidural anesthesia during LC for elderly patients can reduce the occurrence of intraoperative stress responses and have more steady hemodynamic,better anesthetic effect and faster recovery.But it may cause the incidence of nausea,headache and other postoperative adverse reactions increase.

Objective To observe the expression of brain-derived neurotrophical factor (BDNF) in injury spinal cord after transplantation olfactory ensheathing cells (OECs), and to investigate the mechanism of OECs repairing spinal cord injury.Methods OECs from GFP transgenic rats were separated and cultured for transplantation. Spinal cord injury rats were separated two groups by random digits table. In experimental group, OECs suspension were transplanted into injured spinal cord following spinal cord injury. In control group, DMEM was transplanted into the injured spinal cord after spinal cord injury. Motor function was evaluated per week after transplantation. The expression levels of BDNF mRNA and protein were detected by using RT-PCR and immunohistochemistry respectively, and compared with those from normal SD rats.Results Motor function of two groups was improved gradually after transplantation. The motor function scores in experimental group was obviously higher than in control group at 21st day after transplantation (P<0.05). A lot of survival GFP OECs distributed around impaired myeloid tissue. At 21st day after transplantation, BDNF mRNA and protein expression in experimental group were strongest (P<0.05), and stronger in control group than in normal group (P<0.05).Conclusion The transplantation of OECs can repair the injured spinal cord by increasing the expression of BDNF mRNA and protein to improve local microenvironment.

AIM: This study aimed at investigating the effects and mechanism of total alkaloids from Rhizoma Coptidis (TA) on ethanol-induced gastric mucosal injury in rats. METHODS: The experimental gastric damages were established by intragastric ethanol, and the protective effects of TA were evaluated by calculating lesion indices contents and superoxide dismutase (SOD) activity from rat gastric mucosa were measured to explore the interrelation between therapeutic effects of TA and these factors. The expressions of neuronal nitrogen monoxide synthase (nNOS), endothelial NOS (eNOS), and inducible NOS (iNOS)from ethanol-damaged gastric mucosa in rats were analysised using immunohistochemical method. RESULTS: TA significantly inhibited the gastric injury induced by ethanol ,in dose-dependent manner,and the effect of TA was superior to that of Berberine (Ber). TA obviously antric mucosa. TA significantly suppressed ethanol-induced decreasing nNOS and eNOS expression and elevation of iNOS expression in rat gastric mucosa. CONCLUSION: Rhizoma Coptidis is a potent candidate in therapeutic drugs of human alcohol-induced gastric injury. Its anti-injury effects involve in Ber and other ingredients of TA. The protective mechanisms of TA involve in inhibiting generation of oxygen-derived free radical, accelerating scavenging of free radicals, relieving lipid peroxidation, and maintaining NO content in normal level by inhibiting decreasing of nNOS and eNOS expression and elevation of iNOS expression.

Objective To analyze the pathogenesis,initially diagnosed symptoms and clinical manifestations of children with chronic kidney disease (CKD) at stage 2 to 5.Methods The data of 108 children who were hospitalized in Children's Hospital Affiliated to Capital Institute of Pediatrics from September 2007 to April 2016 with CKD stage 2 to 5 were retrospectively analyzed.The etiologies,clinical manifestations and examinations were summarized,and the clinical manifestations were compared between the congenital hereditary urinary diseases group and the acquired urinary diseases group.Results (1) In the 108 cases collected,66 cases were male,42 cases were female,aged from 3 months to 15 years and 1 month old.Twenty-four cases were diagnosed at stage 2,26 cases at stage 3,35 cases at stage 4,and 23 cases at stage 5.(2) Twenty-eight kinds of illness were involved in the cause of CKD.Among them,57 cases (52.8％) had congenital anomalies of the kidney and urinary tract,5 cases(4.6％) had hereditary kidney diseases,41 cases (38.0％) had other primary or secondary kidney diseases,and in 5 cases (4.6％) the causes of disease were unknown.(3) For the initially diagnosed symptoms,29 cases(26.9％) were due to complaints associated with kidney disease,36 cases (33.3％) were of other outside kidney symptoms,and 43 cases (39.8 ％) were of negative symptoms.The results of urinary ultrasound were abnormal in 79 cases(73.1％) and 87 cases(80.6％) showed abnormality in urinary analysis.There were 105 cases (97.2％) with abnormal manifestations either in urinary tract ultrasound or in urinary analysis.(4)The ages on diagnosis as CKD in children with congenital hereditary urinary diseases(5.89 years old) were younger than that of children with acquired urinary diseases (9.20 years old),and the difference was significant(Z =-3.434,P =0.001).The frequency of cases with short stature or lower-weight in group of congenital hereditary urinary diseases[66.1％ (41/622 cases),64.5％ (40/62 cases)] were significantly higher than those of the acquired urinary diseases group[43.9％ (18/41cases),43.9％ (18/41 cases)],and the differences were statistically significant(x2 =4.983,4.263,P =0.026,0.039).Conclusions The causes of CKD are complicated,and the congenital anomalies of kidney and urinary tract are the major causes of CKD at stage 2 to 5 in the cases.The initially diagnosed symptoms of CKD are insidious and atypical.The children with congenital hereditary urinary diseases tend to have more serious growth retardation.Urinary analysis and ultrasound may have an important significance for early diagnosis of CKD in children.

Objective To study the clinical and genetic features of Lowe syndrome. Methods The clinical data and test results of OCRL gene from two children with Lowe syndrome were analyzed. The related literatures were reviewed. Re-sults Two male patients all presented with low molecular proteinuria, hypercalciuria, rickets and nephrolithiasis. Patient 2 had renal tubular acidosis, glycosuria and cryptochism. Patient 1 was found to have abnormal vision and congenital cataract soon after birth and treated surgically. Patient 1 also had psychomotor retardation and the cranial magnetic resonance ima-ging (MRI) showed agenesis of the corpus callosum. Patient 2 did not have obviously extra-renal symptoms, but was found to have mild cataract by a meticulous ophthalmological examination. MRI showed cerebral hypoplasia and myelination delay and mental retardation was gradually appeared during follow-up. Two OCRL gene mutations were detected. A splice site mutation NG_008638.1:g.46846-46848delTAA/insC was found in patient 1 and a frame shift mutation NM_000276.3:c.321delC in exon 5 was found in patient 2. Both mutations were not reported previously. Conclusions The diagnosis of Lowe syndrome is mainly by clinical manifestations and test of OCRL gene. Lowe syndrome needs to be included in the differential diagnosis of a patient with congenital cataract and renal tubulopathy. Two novel mutations in the OCRL gene were identiifed.
