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 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 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: 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.

BACKGROUND:Silk fibroin, as an inorganic mineralization template, can induce hydroxyapatite crystal growth, and combined with nano-hydroxyapatite can simulate the inorganic and organic components of natural bone, which is expected to become the most ideal bone graft material. OBJECTIVE:To prepare the silk fibroin/nano-hydroxyapatite composite material and investigate its treatment outcomes in spinal fusion. METHODS:Silk fibroin/nano-hydroxyapatite composite was synthesized by the co precipitation method with silk fibroin and calcium phosphate as raw materials, to simulate the structure and composition of the bone tissue. The crystal phase composition and microstructure of the composite scaffold were analyzed by X-ray diffraction and transmission electron microscope. Osteoblasts were seeded onto the composite, and the cel adhesion and proliferation were observed under inverted microscope. The lumbar posterolateral spinal fusion models were established in the New Zealand rabbits, fol owed by treated with autologous bone graft (control group) and composite (composite group), respectively. The gross, radiological and histological observations of bone fusion were compared between groups. RESULTS AND CONCLUSION:Silk fibroin/nano-hydroxyapatite composite appeared to be fascicular under electron microscope, the length was 200-500 nm and width was 20-30 nm. And the hydroxyapatite was about 200 nm in length and 50 nm in width. X-ray diffraction showed that the bottom of diffraction peak was wide, and the peak was not sharp. Transmission electron microscope found that cel s adhered wel onto the composite scaffold at 2 days. Scanning electron microscope showed that the polygonal, oval or conical cel s covered most of the composite scaffold holes, presented obvious mitotic phase at 5 days. The third generation of MC3T3-E cel s tended to rise at first 3 days, and then decreased. The fusion site of L5-6 transverse process was strong, and non-bony fusion occurred. At the same time, numerous new bones were visible in the composite group. Hematoxylin-eosin staining showed a large number of cel aggregation, abundant osteoblasts surrounding cartilage, and the bone tissues were in a regular arrangement in the composite group. Moreover, irregular trabecular bone with medul ary cavity was found in the composite material. These results suggest that the silk fibroin/nano-hydroxyapatite composite with the similar structure and composition of natural bone can achieve satisfactory fusion effect in the rabbit lumbar posterolateral fusion.

Objective To investigate the value of fused 3D-SPACE and 3D-TOF images in diagnosis of intracranial neurovascular compression syndrome.Methods 26 patients with intracranial neurovascular compression syndrome were examined using 3D-SPACE sequence and 3D-TOF sequence.After 3D-SPACE and 3D-TOF were fused by different times,the quality of image as well as the ability of j udging the relationship between nerves and blood vessels was analyzed and compared between the original images and the fused images.Results In this study,the fused images by adding one 3D-SPACE sequence and one 3D-TOF sequence showed the highest accurate than others(2 1 cases),and the j udgement of the relationship between the responsible blood vessels and nerve accor-ded with the surgical results to the highest extent (P<0.05).Conclusion The fusion image of 3D-SPACE sequence and 3D-TOF se-quence can improve the diagnostic ability of the intracranial neurovascular compression syndrome,and the appropriate proportion of the fusion image can show the relationship between the nerve and blood vessel.

Objective To explore the effects of Shihusan on the intracellular free calcium of human retina cells and the protection from the damage of glutamate. To investigate its function and mechanism in retinal degeneration diseases, and to offer the basis on which to treat the similar disease clinically. Design Experimental study. Participants Retinal cells from normal human eye. Methods Cultivation of human retinal neural cells was perfonned. The changes of fluorescent density of intracellular free calcium of cultured cells labeled with Fluo3/AM before and after adding Shihusan and verapamil were detected with laser scanning confocal microscopy. In addition, the effect of Shihusan on calcium overload provoked by glutamic acid was observed. Main Outcome Measures The level of intracellular free calcium of retinal cells. Results The retinal cells adhered, spread and grew well in vitro. The fluorescence intensity increased 88% in glutamic acid group, decreased 14.8% and 57.3% in Shihusan group and verapamil group respectively. Shihusan couldn't decrease the intracellular Ca2+ that was increased by glutamic acid, but could inhibit the increasing tendency induced by glutamic acid. The difference was significant compared to control group (P=0.000). Conclusions Shihusan might decrease the level of intracellular free calcium in cultured human retinal cells, and resist the damage of glutamate. Its mechanism was related possibly to resisting calcium overload and inhibiting apoptosis.

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.
