The conclusion of this study needs randomized controlled trials with larger samples, multicenter and high quality for further verification.

Syndrome, a very important concept in traditional Chinese medicine (TCM), is the essence and characteristics of TCM theory. Progress of related studies on syndrome will drive the development of TCM. Therefore, clinical and basic researches on syndrome have focused on the hotspot of TCM. In recent 60 years, many scholars have discussed the concept, essence and the establishment of standardization of syndrome from different angles and layers. Although many results have been obtained, there is still a certain one sidedness and dispute. Therefore, looking for a new theoretical tool to reveal the scientific connotation of TCM syndrome is imperative. TCM syndrome and biological entropy belong to two different subject concepts, but can also reveal the physiological and pathological state in the changes of life body growth. This article discussed isomorphism of TCM syndrome and biological entropy from the concept, theoretical background and characteristics, with a purpose to provide certain guiding significance to study and promote standardized researches on TCM syndrome.

Objective To provide nutritional supportive scheme for patients with radiation injury through the treatment of the one exposed to Nanjing 192Ir source accident.Methods The reasonable nutrition treatment scheme was made on the basis of dietary survey and nutritional index monitoring during clinical stages of the patient,including body weight,body mass index(BMI),biochemical indexes,electrolyte,etc.,as well as metabolic cart determination of resting energy expenditure (REE).Results Patient on admission (days 5 post-irradiated) weighing 42.5 kg,172 days after the first irradiated (the first skin grafting) fell to a minimum of 36 kg,then gradually rise,hen rose back to normal range on days 383 before discharge.Normal admission hemoglobin was 135 g/L,172 d after irradiated to a minimum of 54 g/L,normal discharge;when lymphocytes admission low as 0.5 × 109/L,58 days back to normal after exposure,172 days after irradiated down to 0.4 × 109/L.Serum albumin was normal admission 41.2 g/L,172 days after irradiated down to 25.3 g/L.The normal level of serum prealbumin was 0.22 g/L,248 days to a minimum of 0.04 g/L,the basic return to normal at discharge was 0.17 g/L.Admission normal liver function,bilirubin index slightly higher,the all in one parenteral nutrition after about 2.5 months later,bilirubin and liver function indicators were gradually increased,the adjusted treatment and nutrition liver and gallbladder and other gradually returned to normal after treatment.REE and the body weight were determined by metabolic cart on days 294,308 and 342 for the energy requirements.Conclusions For patient with radiation injury,appropriate nutrition therapy is a key method for the clinical treatment and rehabilitation,which can maintain the nutritional status of patients and improve clinical treatment.

Objective To investigate the effect of repetitive transcranial magnetic stimulation (rTMS) on the proliferation of neural stem cells in the subventricular zone (SVZ) and the expression of miR-9 in the ipsilesional hemisphere of rats with focal cerebral ischemia.Methods A rat model of acute focal cerebral ischemia was established using transient middle cerebral artery occlusion (tMCAO).Rats were then randomly assigned to a sham group,a control group or an rTMS group.Daily rTMS treatments (10 trains with 30 pulses per train and 50-second breaks between trains at 120％ of the resting motor threshold) were targeted at the ipsilesional MI cortex beginning one day after the tMCAO.After the treatment the proliferation of neural stem cells in the ipsilesional SVZ was identified by double immunofluorescence staining (BrdU/nestin).The expression of miR-9 was evaluated using quantitative PCR.Results Compared with the other two groups,BrdU + Nestin + cells in the ipsilesional SVZs of the rTMS group increased and the expression of miR-9 decreased significantly.Conclusion rTMS can promote the proliferation of neural stem cells and inhibit the expression of miR-9 in the ipsilesional hemisphere after focal cerebral ischemia.

OBJECTIVETo explore the effects of early intervention of acupuncture on urinary function reconstruction of neurogenic bladder after spinal cord injury, so as to find the optimal treatment timing of acupuncture.

METHODSFifty-three patients of neurogenic bladder after spinal cord injury were randomly divided into a prior-to-catheter group (25 cases) and a posterior-to-catheter group (28 cases). For the prior-to-catheter group, one week before the removal of catheter, acupoints on the abdomen and back such as Guanyuan (CV 4), Zhongji (CV 3), Baliao (Shangliao (BL 31), Ciliao (BL 32), Zhongliao (BL 33), Xialiao (BL 34), Jiaji (EX-B 2) and acupoints at distal end such as Zusanli (ST 36) and Sanyinjiao (SP 6) were selected; after the catheter removal, simple method. of water column was used to measure bladder capacity pressure to classify the type of bladder, and then different acupuncture manipulations were given; intermittent catheterization was performed if condition was allowed. The posterior-to-catheter group applied identical treatment after removal of catheter as the prior-to-catheter group. The treatment was given 5 times per week; after one-month treatment, five aspects including the time of first effective urination, time of establishing reflex urination, average residual volume of urine, time of residual urine less than 100 mL and quality of life (QOL) were evaluated.

RESULTSAfter treatment, the time of first effective urination, time of establishing reflex urination, average residual volume of urine and time of residual urineless than 100 mL in the prior-to-catheter group were all superior to those in the posterior-to-catheter group (all P<0. 05) ; the score of QOL was improved in two groups after treatment (both P<0. 01), but the difference between two groups was not statistically significant (P>0. 05); each index of urination function was not significant among patients with different injured segments of spinal cord (all P>0. 05).

CONCLUSIONThe early intervention of acupuncture (prior to catheter) has obvious improving function on establishing balanced bladder in patients with neurogenic bladder after spinal cord injury, which is superior to acupuncture intervention after removal of catheter, however, the effects of different injured segments on establishing balanced bladder are not different.

Objective To assess the impact of glycemic variability on left ventricular function in patients with acute ST-segment elevation myocardial infarction (STEMI) and type 2 diabetes.Methods Three hundred and three patients with type 2 diabetes and first STEMI between May 2014 and December 2016 in Beijing Anzhen Hospital,Capital Medical University were seclected continuously.All participants' continuous glucose monitoring system (CGMS) parameters,echocardiogram and biochemical characteristics were measured at baseline.According to the level of mean amplitude of glycemic excursion (MAGE) which is the gold indicator to present glycemic variability patients were classified into low MAGE group (n=182) and high MAGE group (n =117).Impact of glycemic variability on left ventricular function in patients with acute ST-segment elevation myocardial infarction and type 2 diabetes were analysed.Results (1) Cardiac function evaluation:The level of left ventricular ejection fraction (LVEF) were significantly lower in high MAGE group than in low MAGE group ((43.8± 7.2) vs.(52.3± 8.5) ％,t =4.912,P＜ 0.001).There were significant differences between the two groups in Killip classification (x2 =49.931,P＜ 0.001).(2) Pearson correlation analysis shows that LVEF negatively correlated with the levels of MAGE(r=-0.367,P＜0.001),postprandial glucose excursion (PPGE) (r=-0.274,P=0.003),Hemoglobin A1c(HbA1c) (r=-0.238,P =0.010),serum highsensitive C-reactive protein (hs-CRP) via logarithmic transformation (r =-0.245,P =0.008) and fasting plasma glucose (FPG) (r =-0.229,P =0.021).Killip classification positively correlated with the levels of MAGE (r =0.301,P ＜ 0.001),PPGE (r =0.228,P =0.022),hs-CRP via logarithmic transformation (r =0.234,P =0.019),H bA 1 c (r =0.195,P =0.041) and FPG (r =0.193,P =0.045).(3) Multiple stepwise regression analysis and multivariate Logistic regression analysis indicated that the level of MAGE was independent risk factor of LVEF (t =-2.279,P =0.005,95％ CI(-3.160 -0.219)) and the level of MAGE was an independent risk factor of Killip classification (Waldx2 =5.673,OR=1.665,95％CI(1.095-2.534),P=0.017).Conclusion Glycemic variability is associated with the presence and severity of left ventricular function in patients with STEMI and type 2 diabetes.

Objective:To study the impact of excessive iodide intake during pregnancy and lactation on lipid metabolism in offspring male rats.Methods:Forty-eight six-week-old Wistar rats (half male and half female) were fed adaptively for one week. The cage was closed according to the ratio of male and female 1∶1. The pregnant rats were divided into two groups according to their weight (220-240 g) by random number table. (1) 10 times high iodine (10 HI) intake during pregnancy and lactation until the postnatal day 21 (PN21) of their offspring: pregnant rats were divided into normal iodine group (NI group, drinking deionized water), 10 HI group (drinking potassium iodide solution with iodine content of 2 250 μg/L). Breast milk was used to feed the offspring rats to PN21, and the offspring male rats were taken as the research subjects, with 6 rats in each group. (2) 100 times high iodine (100 HI) intake during pregnancy and lactation to the offspring postnatal day 120 (PN120): pregnant rats were divided into NI group (drinking deionized water) and 100 HI group (drinking potassium iodide solution with iodine content of 24 750 μg/L). After feeding the offspring rats with breast milk until PN21, the offspring were continued to drink potassium iodide solution with the same iodine content as the mother's to PN120. The offspring male rats were taken as the research subjects, with 6 rats in each group. The levels of free triiodothyronine (FT 3), free thyroxine (FT 4), thyrotropin (TSH) in serum, low-density lipoprotein cholesterol (LDL-C), triglyceride (TG) and total cholesterol (TC) in serum and liver tissue homogenates were measured by enzyme-linked immunosorbent assay (ELISA). The mRNA expression of cholesterol 7α-hydroxylase (CYP7A), low-density lipoprotein receptors (LDLR), sterol regulatory element-binding protein (SREBP)-1c, malic enzyme (ME) and thyroid hormone receptor β (TRβ) in the liver tissue were measured by real-time quantitative PCR. Results:(1) Effects of 10 HI intake during pregnancy and lactation on PN21 offspring male rats: compared with NI and 10 HI groups, the serum FT 3 [(7.53 ± 0.74), (8.88 ± 0.99) pmol/L], FT 4 [(5.58 ± 0.56), (7.68 ± 0.30) pmol/L], TSH levels [(16.69 ± 1.05), (14.49 ± 0.16) ng/ml] of offspring male rats were statistically significant ( t=- 2.91,-8.76, 3.59, P < 0.05). The levels of LDL-C, TG, TC in serum and liver of offspring male rats of 10 HI group were significantly lower than those of NI group ( t=3.28, 8.71, 3.44, 3.70, 3.49, 2.74, P < 0.05). The differences of mRNA expression levels of LDLR, ME, SREBP-1c in the liver of PN21 offspring male rats of 10 HI and NI groups were statistically significant ( t=- 3.50,-3.92, 5.58, P < 0.05). Among them, the levels of LDLR and ME in 10 HI group were higher than those in NI group, while the level of SREBP-1c in 10 HI group was lower than that in NI group. There no significant difference in CYP7A and TRβ mRNA levels between the two groups ( t=- 2.44, 3.20, P > 0.05). (2) Effects of 100 HI intake during pregnancy and lactation on PN120 offspring male rats: there were significant differences in serum FT 3, FT 4 and TSH levels of offspring male rats between 100 HI and NI groups ( t=- 4.39,-3.19, 4.72, P < 0.05). The levels of serum FT 3 and FT 4 in 100 HI group were lower than those in NI group, and the level of TSH in 100 HI group was higher than that in NI group ( P < 0.05). Compared with NI group, the serum and liver LDL-C, TG and TC levels in the offspring male rats of 100 HI group were significantly higher ( t=4.49, 12.85, 16.62, 4.35, 11.04, 16.01, P < 0.05). The differences of CYP7A, LDLR, ME, TRβ and SREBP-1c mRNA levels in liver of PN120 offspring male rats of 100 HI and NI groups were statistically significant ( t=26.40, 54.85,-10.98, 32.52, 10.50, P < 0.05). Among them, the CYP7A, LDLR, ME and TRβ mRNA levels in 100 HI group were lower than those of NI group, while the SREBP-1c mRNA level was higher than that of NI group ( P < 0.05). Conclusions:10 HI intake during pregnancy and lactation to the offspring male rats PN21 showed the serological changes of hyperthyroidism, the levels of blood lipids and liver lipids decreased, the levels of LDLR and ME mRNA increased, and SREBP-1c mRNA decreased in liver. However, 100 HI intake during pregnancy and lactation to the offspring male rats PN120 showed serological changes of hypothyroidism, the levels of blood lipids and liver lipids increased, the levels of CYP7A, LDLR, ME mRNA decreased, and SREBP-1c mRNA increased in liver.

Objective To explore the correlation between apolipoprotein E (ApoE) gene polymorphism and urine Alzheimer-associated neuronal thread protein (AD7c-NTP) level in patients with Alzheimer's disease (AD) and mild cognitive impairment (MCI).Methods The cognitive function of 30 AD patients (AD group),30 MCI patients (MCI group) and 30 normal controls (NC group) was evaluated by neuropsychological batteries like MMSE,the Cambridge Cognitive Examination-Chinese Version (CAMCOG-C),etc.ELISA was used to test the urine level of AD7c-NTP.The genotypes of ApoE were analyzed by the high-resolution melting assay in blood samples.Results Compared with the NC group (0.59 (0.40,0.66) ng/ml),the urine level of AD7c-NTP in the AD group (1.03(0.80,1.41) ng/ml) and the MCI group (0.69(0.53,0.91) ng/ml) was increased (Z =33.727,P ＜0.01).The urine level of AD7c-NTP in the AD group was higher than that in the MCI group (Z =8.232,P ＜ 0.05).The level of AD7c-NTP in urine was negatively correlated with MMSE and CAMCOG-C scores (rMMSE =-0.604,P ＜ 0.01;rCAMCOG-C =-0.486,P ＜ 0.01).According to receiver operating characteristic curve,the optimal cutoff point of AD7c-NTP in urine for diagnosis of patients including AD and MCI was 0.70 ng/ml,with sensitivity of 71.7％ and specificity of 83.3％,and area under the curve of 0.82 (95％ CI 0.73-0.90,P ＜0.05).There were four genotypes comprising ε2/3,ε3/3,ε3/4 and ε4/4 for ApoE gene.The frequencies of ε4 carriers were 46.7％ (14/30),23.3％ (7/30) and 23.3％ (7/30) in the AD,MCI and NC groups,respectively.There was a notable increase in urine AD7c-NTP and a significant decrease in CAMCOG-C scores in MCI patients who harbored the ApoE ε4 allele (ZAD7c-NTP =4.857,P ＜ 0.05;ZCAMCOG-C =4.284,P ＜0.05).Conclusions The urine level of AD7c-NTP was significantly increased in AD and MCI patients,the higher the level of AD7c-NTP,the more serious the cognitive impairment.The ε4 carriers exhibited higher urine level of AD7c-NTP,but worse cognitive function compared to ε4 non-carriers in the MCI group.

Objective:To construct a recombinant herpes simplex virus 2 (HSV-2) expressing enhanced green fluorescent protein (EGFP) using clustered, regularly interspaced, short palindromic repeat/CRISPR-associated nuclease 9 (CRISPR/Cas9) technology.Methods:Four strategies for inserting exogenous EGFP gene into HSV-2 genome using CRISPR/Cas9 technology were designed: (1) conventional homology-directed repair: circular two homology arm donor-mediated gene knock-in; (2) linearized single homology arm donor-mediated gene knock-in; (3) homology-independent targeted integration; (4) conventional homology-directed repair-mediated by cell lines stably expressing Cas9 and sgRNA.Results:The recombinant virus HSV-2-EGFP was successfully constructed based on the second, the third and the fourth strategies. The second strategy was the most efficient, followed by the third and the fourth strategies. The purified recombinant virus could stably express green fluorescent protein in seven passages and shared similar growth characteristics in Vero cells to the parental virus.Conclusions:Linearized single homology arm donor could increase the efficiency of gene knock-in, and cell lines stably expressing Cas9 and sgRNA could increase the efficiency of gene knock-in mediated by homology-directed repair.
