Long non-coding RNAs (lncRNA) play important roles in many biological processes.However,compared with other types of RNAs,limited research has been conducted on lncRNA,mostly concerning its relationship with tumor,and there are much fewer studies on its relationship with atherosclerosis.In this article,we summarized the latest research findings in this field,with an emphasis on the importance of IncRNA in atherosclerosis.The value of lncRNA in targeted therapy of atherosclerotic disorders is also discussed.

Objective To assess the efficacy of the mixtures of different concentrations of ropivacaine(R) and chloroprocaine(C)for epidural anesthesia in patients undergoing hysterectomy.Methods Sixty ASAⅠorⅡpatients aged 27-56 weighing 45-75 kg undergoing elective hysterectomy were randomly divided into 4 groups(n= 15 each);groupⅠ0.75% R alone;groupⅡ0.5% R-1% C;groupⅢ0.5% R-1.5% C and groupⅣ0.75% R+1% C.The epidural catheter was placed at L_(2,3)interspace and advanced 3.5 cm into the epidural space in cephalad direction.A total of 22 ml of epidural solution was injected in each group.The onset time,block height and duration of sensory block and the onset time,degree and duration of motor block(using Bromage scale)were assessed.The use of supplementary drugs(ketamine and ephedrine)and side effects were recorded.Results The onset time of sensory and motor block was significantly shorter in groupⅡ,ⅢandⅣthan in groupⅠ(0.75% R alone).The duration of sensory and motor block was significantly shorter in groupⅡandⅢthan in groupⅠandⅣ.The incidence of hypotension was significantly increased but the incidence of discomfort produced by traction on the viscera during operation was reduced in groupⅣas compared with groupⅠ.Conclusion The anesthetic efficacy of epidural 0.5% ropivacaine is significantly enhanced when mixed with 1.0% or 1.5% chloroprocaine.

Objective The purpose of this study was to evaluate the perioperative management of patients with recent myocardial infarction (MI) undergoing non-cardiac surgery.Methods Twelve patients underwent general or thoracic surgery on the 72th to 175th day after acute MI. Their mean age was (67?4 ) years old. All patients received epidural block or epidural block combined with general anesthesia. Epidural catheter was left in place for postoperative analgesia.Results All patients underwent operation smoothly. During operation ECG monitoring showed no ischemic ST-T changes. Postoperative pain relif was satisfactory. No acute heart failure or myocardial reinfarction occurred during their stay in hospital.Conclusions In patients who had recent MI the time interval between the first MI and surgery should not be the only factor in the risk assessment. Other factors such as urgency of surgery, the severity of coronary artery disease, exercise tolerance and complexity of surgery should also be considered. Adequate preoperative evaluation and preparation and maintenance of cardiac function during perioperative period are crucial to the safety of surgery. Epidural block combined with general anesthesia is the anesthesia of choice for patient with recent MI undergoing non-cardiac surgery.

Objective: This experiment was designed to study the change of nitric oxide (NO) content in different parts of brain in rats suffering from iodine deficiency(ID) and hypothyroidism since their fetal period. Methods: Iodine deficiency animal model was made and NO content in hippocampus(HPC), cerebellum (CE) and cortex(CO) were measured by using NO test kit. Results: Urinary iodine and serum T 3?T 4 concentrations significantly decreased and learning-memory capacity was impaired in ID rats. NO content was significantly lower in HPC and CE in ID rats than in control rats.(HPC:11.61?2.31/2.3?1 18 ?mol/g Prot;CE:10.77?5.16/4.70?1.95 ?mol/g Prot).No difference was found in cortex. Conclusion: Iodine deficiency and hypothyroidism since fetal period could affect NO level in rat brain. Different parts of brain have different sensitivity to ID and hypothyroidism.The changes of NO content in hippocampus may contribute to the learning-memory impairment in ID rats.

OBJECTIVE:To investigate the characteristics of serious ADR in psychiatric hospital,and to provide reference for effective and safe use of drugs in the clinic. METHODS:114 cases of serious ADR in our hospital from 2004 to 2015 were ana-lyzed retrospectively in terms of general information,primary disease,route of administration,dosage form,drug types,organs or systems involved in ADR and clinical manifestations,top 5 ADR-inducing drugs and main clinical manifestations,etc. RESULTS:Of 114 serious ADR cases,the number of female was more than that of male(71/43). Patients aged 21-30 years old took up the greatest proprotion(35 cases,30.70%). The main involved primary disease was schizophrenia(54 cases,47.37%). Oral adminis-tration-induced ADR was most common(103 cases,90.35%). The main involved drugs were antipsychotics,occupying the great-est proportion(75 cases,65.79%). Digestive system involved was the most common(53 cases,42.74%), Olanzapine tablets had the highest incidence of serious ADR (23 cases,18.55%),the main clinical manifestation were both abnormal liver function. There were 8 cases of new serious ADR (7.02%). Most of the ADR can be cured after drug withdrawal or countermeasures,no death case was found. CONCLUSIONS:Psychiatric drugs can induce serious ADR as treat psychiatric disease,among which the in-cidence of ADR induced by Olanzapine tablets is the highest and mainly manifestes digestive system symptoms. It is suggested to strengthen serious ADR monitoring to promote the safe use of drugs.

Objective Although heart transplantation surgery has become more common,little is known about the psychological status of patients waiting for a heart transplant.Method Ninety-three patients registered for heart transplantation from March 2013 to March 2014 in a large general hospital in Shanghai were assessed by a psychiatrist using the Hamilton Depression Scale (17 items) and the Hamilton Anxiety Scale.Out of them 36 were preoperatively admitted to the Cardiac Surgery Department.The scales were assessed repeatedly at the 1st day,3rd day,7th day,10th day and so on until the operation took place.Result The mean scores of HAMD and HAMA of 93 patients in the waiting list were separately 13.11 ±3.81 and 14.20±4.57.Among them 18(19.4％) were classified as moderately depressed,31(33.3％) had moderately anxious symptoms,and 14(14.1％) had severe anxious symptoms.Thirty-six patients were preoperatively admitted to hospital.Their mean scores of HAMD and HAMA were separately 13.19-± 3.82 and 16.17 ± 4.35.Among them 7(19.4％) were classified as moderate depression at the time of admission,16 (44.4％) had moderately anxious symptoms and 9 (25.0％) had severe anxious symptoms.The scores of HAMD had significant difference (t =3.383,P =0.002) before and after admission.Paired t test was separately conducted to analyze the first assessment and the 3rd-day assessment of HAMA and HAMD total scores after admission of all the inpatients.The results showed the scores were statistically different (for HAMA,t =2.786,P =0.009; for HAMD,t =14.024,P =0.000).Repeated ANOVA was used to analyze the recipients who had three assessments.The results had statistical difference (for HAMA,F =4.568,P=0.020; for HAMD,F=5.626,P =0.034) and the difference of HAMD score at different time points had a linear trend (F =8.273,P =0.013).Conclusion After hospital admission,the depression symptoms will be significantly alleviated.When waiting for the transplant in the hospital,the anxiety symptoms alleviate slightly in three days and then aggravate significantly.The depression symptoms alleviate slightly continuously.

Objective To explore the bone marrow stromal cells,anti-late antigen-4 (VLA-4) antibody (aVLA-4),cytarabine (Ara-C) on the proliferation and apoptosis of leukemia HL-60 cells.Methods The experiment was divided into five groups:HL-60 cells were cultured alone (control group),HL-60 cells and stromal cells group (stromal cells group),HL-60 cells + stromal cells + aVLA-4 (antibody group),HL-60 cells + stromal cells + Ara-C group (drug group),HL-60 cells + stromal cells + aVLA-4 + Ara-C group (antibody +drug group).Cell proliferation or inhibition rate was detected by CCK-8 method,the HL-60 cells apoptosis was detected by flow cytometry.The expression of anti-apoptotic gene bcl-2 in HL-60 cells was determined by Western blot.Results After 24 h and 48 h,treatment,the number of the stromal cells group HL-60 cells were higher than that of the control group with significant difference cultured [(7.2±0.3)×1O5/ml vs (5.3±0.4)×105/ml,(8.4±0.2)×105/ml vs (6.8±0.3)×105/m1,P ＜ 0.001],while the HL-60 cell proliferation inhibition rate [(24.3±2.1) ％,(37.0±2.6) ％,(65.6±3.8) ％] and apoptosis rate [(5.7±0.6) ％,(8.0±0.5) ％,(10.4±0.9) ％,(16.5±0.7) ％] of antibody group,drug group,antibody + drug group were higher than the control group with a difference of statistically significant (P ＜ 0.05),and the increase of antibody + drug group was most obvious.With the decreasing of the bcl-2 protein expression,which was most the decrease of antibody + drug group was most obvious.Conclusion Bone marrow stromal cells can stimulate the proliferation of leukemia cells,aVLA-4 interference the interaction between stromal cells and leukemia cells can enhance the chemosensitivity of leukemia cells to Ara-C.

BACKGROUND:Currently, surgical implant fixation is mainly applied for spinal tuberculosis. How to choose implant materials, however, is stil under discussion.OBJECTIVE:To compare the biocompatibility and mechanical properties of titanium al oy and stainless steel for rabbit spinal tuberculosis. METHODS:Thirty rabbits were chosen to prepare spinal tuberculosis models. Then, the rabbits were equivalently randomized into two groups, which underwent implant fixation with stainless steel or titanium al oy, respectively. At 30 days after implantation, biocompatibility and biomechanical properties of the two materials in the repaired region of spine were observed and detected, respectively. RESULTS AND CONCLUSION:In view of the biocompatibility, infection and immunological rejection could not been found in the titanium al oy group;in contrast, infection appeared in three rabbits of the stainless steel group. Flexion, extension and lateral bending displacements under the spinal loading in the titanium al oy group were significantly less than those in the stainless steel group (P<0.05);axial pul-out strength in the titanium al oy group was significantly higher than that in the stainless steel group (P<0.05);flexion, extension, lateral bending and axial compression in the titanium al oy group were significantly greater than those in the stainless steel group (P<0.05). In conclusion, titanium al oy material has good biocompatibility that can be used to restore and maintain the spinal stability.

BACKGROUND:Although the traditional surgical treatment can improve the symptoms of patients with senile osteoporotic vertebral fracture, the treatment easily produces bone graft fusion failure and pseudoarticulation formation and affects clinical effects. OBJECTIVE:To investigate biomechanical properties of anterior cervical pedicle screw and the effects on osteoporotic vertebral stability. METHODS:A total of 16 fresh cadaver cervical specimens contained 64 motion segments (C3-4, C4-5, C5-6 and C6-7). The 64 segments by the way of implantation were randomly divided into ordinary anterior locking screw fixation group and lower anterior vertebral pedicle screw system group (32 segments per group). The mechanical properties were determined on the biomechanical testing machine for each group. RESULTS AND CONCLUSION:(1) Biomechanics:Compared with the ordinary anterior locking screw fixation group, the maximum pul-out strength, screw path length, postoperative vertebral column height, the maximum surface strain, strain maximum and the range of maximum values were increased in the lower anterior vertebral pedicle screw system group (P<0.05). (2) Results suggest that compared with the ordinary anterior locking screw fixation group, lower cervical anterior pedicle screw required larger extraction force and was more stable for osteoporotic vertebrae.
