ABSTRACT
Post-stroke depression (PSD) is a serious and common complication of stroke, which seriously affects the rehabilitation of stroke patients. To date, the pathogenesis of PSD is unclear and effective treatments remain unavailable. Here, we established a mouse model of PSD through photothrombosis-induced focal ischemia. By using a combination of brain imaging, transcriptome sequencing, and bioinformatics analysis, we found that the hippocampus of PSD mice had a significantly lower metabolic level than other brain regions. RNA sequencing revealed a significant reduction of miR34b-3p, which was expressed in hippocampal neurons and inhibited the translation of eukaryotic translation initiation factor 4E (eIF4E). Furthermore, silencing eIF4E inactivated microglia, inhibited neuroinflammation, and abolished the depression-like behaviors in PSD mice. Together, our data demonstrated that insufficient miR34b-3p after stroke cannot inhibit eIF4E translation, which causes PSD by the activation of microglia in the hippocampus. Therefore, miR34b-3p and eIF4E may serve as potential therapeutic targets for the treatment of PSD.

<p><b>OBJECTIVE</b>To investigate the efficacy of single-hand four-needle suture with sled-shaped needle three-tail fixed stitch in closure of pesudohernia sac of direct hernia under transabdominal preperitoneal (TAPP) inguinal hernia repair.</p><p><b>METHODS</b>A randomized controlled trail was conducted on adult patients with unilateral direct inguinal hernia undergoing laparoscopic TAPP repair from January 2014 to January 2018 at the Sixth Affiliated Hospital of Sun Yat-sen University. A total of 156 patients were enrolled prospectively in the study and were randomly divided into single-hand four-needle suture group (trial group, 76 cases) and traditional tacking group (control group, 80 cases). In trial group, sled-shaped needle three-tail knot-free stitch was applied to the continuous four-needle suture. The sled-shaped needle three-tail fixed stitch was made as follows: straighten the tail of a 3-0, 1/2-circle looper VICRYL Rapide into a sled shape; use suture overlap method to make and tighten a single knot; thread the end of the needle into the single knot loop;knot two ends of the thread next to the first knot; tighten the second knot, leaving about 12 cm to the end of the needle;cut the end of the loop (leaving about 0.6 cm) and the other end of the thread(leaving about 1.5 cm). In the control group, a hernia repair tack was used to fix the pseudohernia sac on pectineal ligament. This study was approved by the Hospital Ethics Committee(approval number: L2014ZSLYEC-016). Operation time, pseudoherina sac closure time, hospitalization cost, morbidity of postoperative complication, VAS score and postoperative recurrence were compared between two groups.</p><p><b>RESULTS</b>All the patients completed operations successfully. There were no significant differences between trial group and control group in age [(60.2±0.4) years vs. (61.1±0.7) years)], gender (male ratio 93.4% vs. 92.5%), BMI [(25.1±0.2) kg/m vs. (24.9±0.2) kg/m ], defection area [(16.1±0.4) cm vs. (15.7±0.7) cm ] (all P > 0.05). As compared to control group, trial group had longer operative time[(34.2±1.9) minutes vs. (30.3±1.1) minutes, t=5.484, P=0.045], longer closure time of psudohernia sac [(4.2±0.5) minutes vs. (1.8±0.7) minutes, t=7.423, P=0.031], but lower VAS score (3.2±0.1 vs. 5.3±0.6, t=-3.186, P=0.015) and lower total cost [(9 897.3±104.4) yuan vs. (12 325.6±169.7) yuan, t=-3.972, P=0.023]. No severe complication and death were found in either groups intra-operatively and postoperatively. No mesh infection and relapse occurred during postoperative follow-up of 1-24 (12.0±1.2) months. During follow-up, seroma occurred in 2 cases (2.6%) of trial group and 3 cases (3.8%) of control group without significant difference (χ =1.284, P=0.799), and all were absorbed and disappeared within 30 days after local application of mirabilite.</p><p><b>CONCLUSION</b>Compared to tack fix method, single-hand four-needle suture with sled-shaped needle three-tail fixed stitch can effectively close pseudohernia sac, reduce hospitalization cost and ameliorate postoperative pain in TAPP repair, which is worth promotion.</p>

Objective@#To investigate the effect of dietary control combined with different exercise modes on plasma vaspin, irisin, and metabolic parameters in patients with non-alcoholic fatty liver disease (NAFLD) through a randomized open parallel-controlled study.@*Methods@#The patients aged 30-65 years who visited Tianjin Third Central Hospital from January 2013 to December 2014 and were diagnosed with NAFLD by liver ultrasound and fat content determination were screening, and 474 patients were enrolled in this randomized controlled trial and divided into aerobic exercise group, resistance exercise group, and control group. All patients received dietary intervention. The three groups were compared in terms of biochemical parameters, fat content, NFS score, energy metabolic parameters, body composition index, and levels of vaspin and irisin at baseline and after 6 months of intervention. SPSS 19.0 was used for statistical analysis. The t-test, the Mann-Whitney U test, the chi-square test, and an analysis of variance were used for comparison between groups. The multiple imputation method was used for missing data, and the results were included in the intention-to-treat analysis.@*Results@#There were no significant differences in age, sex, anthropometrical parameters, and biochemical parameters between the three groups at baseline. Compared with dietary control alone, aerobic exercise and resistance exercise helped to achieve significant reductions in waist circumference, diastolic pressure, percentage of body fat, volatile fatty acid, fasting blood glucose, homeostasis model assessment of insulin resistance, triglyceride, low-density lipoprotein cholesterol, free fatty acid, uric acid, alanine aminotransferase, and liver fat content after 6 months of intervention (P < 0.05). The aerobic exercise group had a significant increase in non-protein respiratory quotient and significant reductions in body mass index and aspartate aminotransferase after intervention, as well as a significant increase in resting energy expenditure and significant reductions in abdominal fat ratio and total cholesterol after 6 months of resistance exercise (P < 0.05). The aerobic exercise group and the resistance exercise group had a significant reduction in vaspin and a significant increase in irisin after intervention (P < 0.05), and the resistance exercise group had significantly greater changes in these two adipokines than the aerobic exercise group (P < 0.05).@*Conclusion@#Exercise therapy is an effective method for the treatment of metabolism-associated diseases, and a combination of resistance and aerobic exercises is more reasonable and effective in clinical practice. As a relatively safe exercise mode, resistance exercise can also effectively improve the metabolic state of NAFLD patients.
ABSTRACT
Objective To observe the clinical efficacy of grain-sized moxibustion at Yongquan (KI 1) plus electroacupuncture in treating lumbar intervertebral disc herniation (LIDH).Method Fifty LIDH patients were randomized into a treatment group and a control group, 25 cases in each group. The treatment group was intervened by grain-sized moxibustion plus electroacupuncture, while the control group was by dry electroacupuncture. The Visual Analogue Scale (VAS) and Japanese Orthopaedic Association (JOA) score were observed, and the clinical efficacies were compared.Result After treatment, the VAS and JOA scores were significantly different from that before treatment in both groups (P<0.01). After treatment, the VAS and JOA scores in the treatment group were significantly different from that in the control group (P<0.01,P<0.05). The recovery plus markedly-effective rate and total effective rate were respectively 72.0% and 96.0% in the treatment group, versus 52.0% and 80.0% in the control group, and there was a significant difference in comparing the recovery plus markedly-effective rate (P<0.01).Conclusion Grain-sized moxibustion at Yongquan (KI 1) plus electroacupuncture is an effective approach in treating LIDH.
ABSTRACT
Radiotherapy is a treatment for cancer with undesired by-effects. In order to develop a new radiation protective agent that could reduce the by-effects, we tried to express and purify human cryptochrome 1 (hCRY1). The coding sequence of hCRY1 was inserted into prokaryotic expression plasmid pET28a(+), and this protein was purified from Escherichia coli BL21(DE3) after IPTG induction, ultrasonication, inclusion body dissolution, gradient dialysis, nickel column purification and ultrafiltration. The yield of hCRY1 in 1 L E. coli culture (LB medium) was about 10-15 mg. The radiation protective efficiency of hCRY1 was monitored by detecting X-ray-induced H2A.X foci in HaCaT cells. The results of immunofluorescence show that hCRY1 significantly reduces X-ray stimulated DNA damage response. The apoptosis of HaCaT cell was also detected, and the repression of H2A.X foci formation was not due to hCRY1's cytotoxity. All these data suggest a potential application of recombinant hCRY1 as a protective agent for radiotherapy.

ABSTRACT
Objective To assay the plasma omentin level in patients of type 2 diabetes mellitus (T2DM) combined with non-alcoholic fatty liver disease (NAFLD) and investigate the relationship between plasma omentin level,glucose and lipid metabolism,insulin resistance and NAFLD.Methods The plasma omentin level was assayed by enzyme-linked immunosorbent assay(ELISA) in all subjects,including patients of T2DM controls with NAFLD (group A,50 cases),T2DM without NAFLD (group B,50 cases),simple with NAFLD(group C,51 cases) and normal controls (group D,49 cases).Meanwhile,blood glucose,glycosylated hemoglobin(HbA1c),lipids and insulin levels were also measured.Body mass index (BMI) and waist-to-hip ratio were evaluated.Insulin sensitivity was assessed by HOMA-IR.Results The plasma omentin level was (17.85 ±3.68),(13.89 ±10.68),(26.05 ±7.26) and (22.92 ±2.71)μg/L in group A,B,C and D respectively.The plasma omentin level of group A and group B was significantly lower than that of group C and group D(P ＜ 0.05).The plasma omentin level of group A was higher than that of group B (P ＜ 0.05).The plasma omentin level of group C was higher than that of group D (P＜ 0.05).Correlation analysis showed that the plasma omentin level was negatively correlated to weight,BMI,waist,triglyceride,fasting blood glucose,fasting insulin (FINS) and HOMA-IR (P ＜0.05 or ＜0.01),and positively correlated to high-density lipoprotein cholesterol (HDL-C)(P ＜0.01).Multiple stepwise regression analysis showed that BMI,HOMA-IR and FINS was independent variable of omentin.The concentration of omentin was 24.82 μ g/L which could predict the risk of NAFLD in people with normal glucose regulation.Conclusions The plasma omentin level is closely correlated with glucose,lipid metabolism and insulin resistance.Plasma omentin may play an important role in the pathogenesis of T2DM and NAFLD.
ABSTRACT
ObjectiveTo explore activity characteristics of diverse autonomic nervous system of armymen with different mental quality levels during dread emotion processes.MethodsMental Quality Questionnaire of Armymen was used to select participants.The activities of the diverse autonomic nervous system of armymen withdifferent mental quality levels during dread emotion processes were discussed by physiological - psychological experiments.Results ( 1 ) Under neutral condition blood volume pulse (BPV) is greater in low mental quality group( ( -0.87 ±0.64)mm Hg) than in high( -0.28 ±0.24)mm Hg).(2) During dread emotion processes the normalized low frequency spectral component(LF) and skin conductance (SC) are greater in low mental quality group ( (6.54 ± 2.96) nU),(0.78 ± 0.11 ) umho) than in moderate ( ( 1.32 ± 1.25 ) nU,( (0.22 ± 0.15 ) umho) and high ((3.51 ±2.28 )nU,((0.30 ±0.12) umho).(3) During dread emotion processes the recovery time of HR and the average recovery time of skin conductance( SC ),skin temperature( ST),blood volume pulse(BVP) and HR are greater in low mental quality ( 61.58 ± 35.66 ) s,( 36.78 ± 18.58 ) s ) than in high ( ( 22.36 ± 6.87 ) s,(56.87 ± 23.98 ) s).(4) In emotional arousal,and low mental quality (0.88 ± 2.54 ) in neutral conditions change their arousal'was significantly greater than the middle (0.57 ± 2.88) and high psychological quality group (0.15 ± 1.87) ; Low mental quality group (2.17 ±2.39) under the conditions of pleasure in the dread was significantlygreater than the middle ( 1.87 ± 1.45 ) and high psychological quality group ( 1.24 ± 1.66).ConclusionThe findings indicate that armymen with low mental quality is more likely to show corresponding physiological arousal and alert status in face of the neutral or weak emotional stimuli.When facing dread emotional stimuli,they would show stronger physiological arousal mainly basing on the excitement of sympathetic nerve system,and such statuswould last much longer to bring about more fierce pain experience.

ABSTRACT
Objective To explore influence of norm-setting three-stage rehabilitation training on hemiplegic stroke patients with movement and cognitive dysfunction. Methods A prospective randomized controlled study and stepwise linear regression analysis was carried out to investigate the early variation factors, which affected the integrated functional recovery of stroke patients. According to variation factors we established our norm-setting three-stage rehabilitation training program. 200 patients were randomly selected, according to the cerebral infarction and cerebral hemorrhage classification, and then randomly divided into the rehabilitation group and the control group with 100 patients in each group. All patients accepted general neurology routine nursing. The rehabilitation group was given an extra norm-setting three-stage rehabilitation training. The improvement of motor and cognitive function were observed. Results The early variation factors of integrated functional outcome were treatment programs, CNFD score, age, diabetes, SFMA score, smoking and the intensity of labor within six months since stroke onset. Movement and cognitive function of the rehabilitation group significantly improved than the control group as well as upon admission on the first, 3rd and 6th months since stroke onset. Conclusions The norm-setting three-stage rehabilitation training obviously promotes the improvement of motor and cognitive function at all stages.
