ObjectiveTo investigate the effect of acupuncture on motor function and serum expressions of TNF-aand IL-6 contents in cerebral hemorrhage rats.MethodSeventy-two male Wistar rats were randomized into sham operation, model and acupuncture groups. A rat model of cerebral hemorrhage was made by intracerebral injection of autoblood. Baihui-to-Qubin acupuncture was performed after successful model making. The TNF-aand IL-6 contents of rat serum were measured by enzyme linked immunosorbent assay at three time points: one, three and seven days.ResultBaihui-to-Qubin acupuncture markedly increased the neurological function score and reduced neurologic deficits in cerebral hemorrhage rats. At the same time point, serum TNF-aand IL-6 contents were significantly lower in the acupuncture group of rats thanin the model and acupuncture group; there were statistically significant differences (P<0.01).ConclusionBaihui-to-Qubin acupuncture can reduce neurologic deficits in cerebral hemorrhage rats. It may be related to decreases in serum TNF-aand IL-6 contents after acupuncture.

Objective To investigate the effect of telerehabilitation on memory disorders. Methods From August, 2010 to April, 2015, 81 patients with memory disorders were randomized into control group (n=26), computer-assisted training group (n=33) and telerehabilita-tion training group (n=22). All the patients accepted medicine to facilitate the recovery of memory. Besides, the computer-assisted training group and the telerehabilitation training group accepted memory-based training programs with cognitive rehabilitation system locally or on network respectively, for six weeks. They were evaluated with Wechsler Memory Scale, Rivermead Behavioural Memory Test-2nd Edition and Rey Auditory Verbal Learning Test before and after training. Results Both computer-assisted and telerehabilitation training groups im-proved in all the assessment after training (t>4.059, P<0.001). There was no significant difference between them (P>0.05). There was no sig-nificant improvement in the control group after training (t<0.771, P>0.05). Conclusion Memory rehabilitation training can significantly im-prove memory abilities, similar with locally or telerehabilitation system.

Objective To determine the impact of uric acid changes on kidney function in middle-aged and elderly women with normal renal function.Methods Serum uric acid and estimated glomerular filtration rate(eGFR) were studied by prospective cohort analysis in 1152 middle-aged and elderly Dalian women with serum uric acid<7 mg/dl, estimated glomerular filtration rate(eGFR)≥90 ml·min-1·(1.73 m2)-1, and age>45 years old.Results The analysis of variance (ANOVA) of clinical indices between baseline and follow-up data showed that an eGFR was decreased after three years in both middle-aged and elderly women even with normal serum uric acid.Compared with those in the lowest guartile subgroup, a significant drop of eGFR to less than 90 ml·min-1·(1.73 m2)-1 was seen in those with the highest guartile of baseline serum uric acid group (OR=1.707, 95%CI 1.192-2.443, P=0.003).Furthermore, there were positive correlations between changes in the levels of serum uric acid and eGFR, and linear regression analysis showed that, as the change level of serum uric acid increased, the change level of eGFR declined(β=1.562, 95%CI 1.050-2.075, P<0.01], and the changing degree of uric acid increase is independent risk factors refor eGFR reductions.Conclusion Reduction in eGFR level is inversely related to serum uric acid in perimenopausal and postmenopausal women.However, our study showed that, women with serum uric acid level ranging from normal, slight increase, and relatively high levels, the increasing degrees of uric acid are independent risk factors responsible for the changing degree of eGFR reduction.

Objective:Based on TGF-β1/Smad3 signal pathway, study the effect of Yiqi-Yangyin-Huoxue-Tongluo Recipe in diabetic rat model. Methods:Forty male SD rats were randomly divided into blank group ( n=10) and diabetic model group ( n=30). Diabetic rats were fed with high sugar and high-fat diet combined with low-dose intraperitoneal injection of STZ. The successful rats were randomly divided into model group ( n=10), traditional Chinese medicine (TCM) group ( n=9) and western medicine group ( n=9). The western medicine group was given trimetazidine hydrochloride tablets 4.16 mg/kg, the TCM group was given Yiqi-Yangyin-Huoxue-Tongluo Recipe 19.1 mg/kg, and the blank group and model group were given the same volume of normal saline, once a day for 20 weeks. The level of fasting blood glucose (FBG) in rats were detected by blood glucose meter; Alkaline hydrolysis was used to detect serum hydroxyproline (Hyp); Enzyme-linked immunosorbent assay (ELISA) to detect serum TGF-β1; Masson staining to observe myocardial fibrosis; Western blotting was used to detect TGF-β1, Smad3, collagen Ⅰ (Col-Ⅰ) and collagen Ⅲ (Col-Ⅲ) protein expression. The mRNA expression of TGF-β1 and Smad3 were detected by real-time quantitative PCR. Results:Compared with the model group, the FBG (19.41 ± 3.65 mmol/L vs. 27.48 ± 2.36 mmol/L), serum Hyp (25.76 ± 1.73 μg/ml vs. 31.71 ± 0.33 μg/ml), TGF-β1 (28.41 ± 0.05 pg/ml vs. 30.82 ± 0.84 pg/ml) of TCM group were significantly reduced ( P<0.05), and myocardial interstitial collagen fibers decreased. The expression of TGF-β1 (0.81 ± 0.02 vs. 0.96 ± 0.08), Smad3 (0.36 ± 0.05 vs. 0.57 ± 0.06), Col-Ⅰ (2.36 ± 0.45 vs. 3.53 ± 0.58), Col-Ⅲ (1.92 ± 0.31 vs. 2.75 ± 0.08) protein in the myocardial tissue of TCM group significantly decreased ( P<0.05), the mRNA expression of TGF-β1 (3.55 ± 0.82 vs. 6.67 ± 1.33) and Smad3 (1.62 ± 0.35 vs. 2.70 ± 0.85) in myocardial tissue significantly decreased ( P<0.05). Conclusions:Yiqi-Yangyin-Huoxue-Tongluo Recipe can effectively treat myocardial fibrosis, and its mechanism may be related to the regulation of TGF-β1/Smad3 signal pathway.

The primary function of cardiac mitochondria is the production of ATP to support heart contraction. Examination of the mitochondrial redox state is therefore crucially important to sensitively detect early signs of mitochondrial function in pathophysiological conditions, such as ischemia, diabetes and heart failure. We study fingerprinting of mitochondrial metabolic oxidative state in living cardiomyocytes with spectrally-resolved fluorescence lifetime spectroscopy of NAD(P)H, the principal electron donor in mitochondrial respiration responsible for vital ATP supply. Here NAD(P)H is studied as a marker for non-invasive fluorescent probing of the mitochondrial function. NAD(P) H fluorescence is recorded in cardiac cells following excitation with 375nm UV-light and detection by spectrally-resolved time-correlated single photon counting (TCSPC), based on the simultaneous measurement of the fluorescence spectra and fluorescence lifetimes. Modulation of NADH production and/or mitochondrial respiration is tested to study dynamic characteristics of NAD(P) H fluorescence decay. Our results show that at least a 3-exponential decay model, with 0.4-0.7ns, 1.2-1.9ns and 8.0-13. Ons lifetime pools is necessary to describe cardiomyocyte autofluorescence (AF) within 420-560nm spectral range. Increased mitochondrial NADH production by ketone bodies enhanced the fluorescence intensity, without significant change in fluorescent lifetimes. Rotenone, the inhibitor of Complex I of the mitochondrial respiratory chain, increased AF intensity and shortened the average fluorescence lifetime. Dinitrophenol (DNP), an uncoupling agent of the mitochondrial oxidative phosphorylation, lowered AF intensity, broadened the spectral shoulder at 520 nm and increased the average fluorescence lifetime. These effects are comparable to the study of NADH fluorescence decay in vitro. In the present contribution we demonstrated that spectrally-resolved fluorescence lifetime technique provides promising new tool for analysis of mitochondrial NAD(P) H fluorescence with good reproducibility in living cardiomyocytes. This approach will enhance our knowledge about cardiomyocyte oxidative metabolism and/or its dysfunction at a cellular level. In the future, this approach can prove helpful in the clinical diagnosis and treatment of mitochondrial disorder.

Objective To analyze and compare the incidence of postoperative complications of acute gangrene appendicitis after laparotomy and laparoscopic surgery.Methods This study retrospectively analyzed of 162 cases of acute gangrenous appendicitis treated in Xilin Guole Meng Hospital from January 2015 to January 2018.There were 96 male patients and 66 female patients;age (43.40 ± 16.21) years.According to different surgical methods,162 patients were divided into two groups:laparoscopic group (n =80) and open group (n =82).Laparoscopic appendectomy was performed in the laparoscopic group,and open appendectomy was performed in the open group.To compare the postoperative complications intraoperative and postoperative data between the two groups.It consists of tump fistula or bead inflammation,postoperative pneumonia,abdominal hemorrhage,deep venous thrombosis,incisional hernia,subcutaneous emphysema,incision infection,intestinal obstruction,celiac sepsis,complained of pain intensity classification method for pain score and antibiotic use time,postoperative extubation time,postoperative exhaust time,postoperative bed for the first time for the first time time,length of hospital stay.The measurement data were expressed by (Mean ± SD) and the t test was used with the groups.The counting data were expressed by the percentage or rate and the x2 test was used among the groups.When the number of single group cases was less than 10 cases,the Fisher exact probability method was used for the calibration test.Results The top three complications were incision infection,intestinal obstruction and empyema.The incidence of postoperative complications in open group and laparoscopy group was 65.9％ (54/82) and 8.8％ (7/80) respectively,and there was significant difference between the two groups (F =56.247,P=0.000).The VRS of the lapamscopic group and the open group were 53 points and 12 points for grade Ⅰ,18 points and 36 points for grade Ⅱ,and 9 points and 34 points for grade Ⅲ,The results showed that the difference between the two groups was statistically significant (x2 =2.45,P =0.01).The time of antibiotic use,postoperative tube extraction,postoperative first exhaust,postoperative first time out of bed and hospitalization in the laparoscopic group were respectively (61.2 ±24.2) d,(4.2 ± 1.2) h,(24.6 ±6.9) h,(4.6 ±2.2) h,(5.5 ±3.6) d and the open group were (72±72.6) d,(7.4 ±2.7) h,(52.2 ±4.8) h,(8.4 ±2.6) h,(13.5 ±8.2) d respectively,the differences were statistically significant (P ＜ 0.05).Conclusion The postoperative complications in laparoscopic group were lower than those in open group,so the laparoscopic group was the first choice for the treatment of acute appendicitis,while the open group was another choice for some patients.

Objective To investigate the effect of rehabilitation on memory deficits after acquired brain injury, to compare different training models of memory rehabilitation and to analyze the possible factors affecting memory rehabilitation. Methods 144 patients with acquired brain injury following memory deficits were randomly assigned to computer-assisted training group, face-to-face training group and control group. Both training groups were given memory-based cognitive training program once a day which sustained 30 minutes for 6 or 12 weeks. The instantaneous memory, short-term memory and long-term memory were evaluated and compared before and after training. The effect of gender, age, education, course, site of injury and coma time on training efficacy were analyszed as well. Results 6 weeks and 12 weeks at training, both computer-assisted and face-to-face training groups showed a significant improvement in memory abilities when compared to controls (P<0.01), with the former making more progress (P<0.01). Negative correlation was found between age and memory performance. Conclusion Effectiveness of memory rehabilitation is proven. 12 weeks training can significantly improve memory. Cognitive training using professional equipment is significantly more effective than the face-to-face training and should be recommended.

Self-injury has become a significant public health problem, especially happens in adolescents. Previous studies have suggested that self-injury is related to numerous factors. At present, the occurrence mechanism of self-injury is still unclear, and there is a lack of reliable biological markers in its diagnosis and therapeutic target so far. Previous studies have suggested that self-injury may be related to hypothalamic pituitary adrenal(HPA) axis, β-endorphins, opioids and other hormones. Hypothalamic pituitary thyroid(HPT) axis and hypothalamic pituitary gonadal(HPG) axis are endocrine systems connecting nerves and hormones. Many studies suggested that various hormones in HPT axis and HPG axis of self-injury patients with other mental disorders (such as major depression and bipolar disorder) were abnormal. At present, there are few studies on the relationship between self-injury and HPT axis and HPG axis. There are differences in results even among studies on the same hormones, and some studies involve suicide attempts and even behaviors. Some studies have confirmed that self-injury is related to suicide, expanding the possibility of exploring the correlation between self-injury and hormones. This study will review the relationship between self-injury and hormonal changes.

BackgroundThe incidence of cognitive impairment in patients with depressive disorder is high， and the causes and mechanisms of which deserve more attention. It is usual that the thyroid hormone levels in patients with depressive disorder alter. Further research is needed to explore whether the cognitive function changes in patients with depressive disorder are related to thyroid hormone levels. ObjectiveTo explore the improvement of cognitive function in patients with first-episode depressive disorder after escitalopram and paroxetine treatment， and to analyse its correlation with thyroid hormone levels， so as to look for potential biomarkers of cognitive function change in patients with depressive disorder. MethodsFrom March 2021 to March 2022， 120 patients who met the diagnostic criteria of the International Classification of Diseases， tenth edition （ICD-10） for depression and were hospitalized at Shandong Mental Health Center were selected as the research objects. They were randomly divided into two groups by random number table method with 60 patients in each group. The two groups were treated with escitalopram （starting dose 5 mg/d） and paroxetine （starting dose 20 mg/d） for 6 weeks. Before and 6 weeks after the treatment， levels of thyroid stimulating hormone （TSH）， free thyroxine （FT4） and free triiodothyronine （FT3） were tested respectively. Depression degree and cognitive function level were assessed using the Hamilton Depression Scale-17 item （HAMD-17） and Montreal Cognitive Assessment （MoCA）， respectively. Pearson or Spearman correlation analysis was used to examine the correlation between the MoCA score difference before and after the treatment and the post-treatment level of thyroid hormone. ResultsBefore and 6 weeks after the treatment， the time effect of HAMD-17 total score in both groups was statistically significant （F=1 236.568， P<0.01）. Also， the time effect， group effect as well as interaction effect of time and group of MoCA total score in both groups were statistically significant （F=79.186， 6.026， 20.417， P<0.05 or 0.01）. The time effect， group effect as well as the interaction effect of time and group for FT3 level and FT4 level were statistically significant in both groups （F=75.973， 20.287， 0.961， 84.194， 0.142， 8.299， P<0.05 or 0.01）. According to the simple effect analysis. After the treatment， the MoCA total score in both groups was higher than that before treatment， while FT3 and FT4 levels were lower than those before treatment （F=15.864， 5.421， 8.524， 6.443， 7.628， 3.639， P<0.01）. After the 6-week treatment， the MoCA total score as well as FT3 and FT4 level differences in escitalopram and paroxetine groups were of statistical significance （t=5.841， -0.705， -2.349， P<0.05 or 0.01）. The MoCA score difference before and after treatment in paroxetine group was positively correlated with FT3 and FT4 levels after treatment （r=0.276， 0.382， P<0.05 or 0.01）. ConclusionBoth escitalopram and paroxetine can improve cognitive function in patients with first-episode depressive disorder. The improvement may be related to the changes in serum FT3 and FT4 levels.
