ABSTRACT
Objective:To analyze the risk factors related to the prognosis of patients with sepsis in intensive care unit (ICU), construct a nomogram model, and verify its predictive efficacy.Methods:A retrospective cohort study was conducted using data from Medical Information Mart for Intensive Care-Ⅳ 0.4 [MIMIC-Ⅳ (version 2.0)]. The information of 6 500 patients with sepsis who meet the diagnostic criteria of Sepsis-3 were collected, including demography characteristics, complications, laboratory indicators within 24 hours after ICU admission, and final outcome. Using a simple random sampling method, the patients were divided into a training set and a validation set at a ratio of 7∶3. The restricted cubic spline (RCS) was used to explore whether there was a linear relationship between each variable and the prognosis, and the nonlinear variables were truncated into categorical variables. All variables were screened by LASSO regression and included in multivariate Cox regression analysis to analyze the death risk factors in ICU patients with sepsis, and construct a nomograph. The consistency index, calibration curve and receiver operator characteristic curve (ROC curve) were used to evaluate the prediction efficiency of nomogram model. The decision curve analysis (DCA) was used to validate the clinical value of the model and its impact on actual decision-making.Results:Among 6 500 patients with sepsis, 4 551 were in the training set and 1 949 were in the validation set. The 28-day, 90-day and 1-year mortality in the training set were 27.73% (1?262/4?551), 34.76% (1?582/4?551), and 42.98% (1?956/4?551), respectively, those in the validation set were 27.24% (531/1?949), 33.91% (661/1?949), and 42.23% (823/1?949), respectively. Both in training set and the validation set, compared with the final survival patients, the death patients were older, and had higher sequential organ failure assessment (SOFA) score and simplified acute physiology scoreⅡ (SAPSⅡ), more comorbidities, less urine output, and more use of vasoactive drugs, kidney replacement therapy, and mechanical ventilation. By RCS analysis, the variables with potential nonlinear correlation with the prognosis risk of septic patients were transformed into categorical variable. The variables screened by LASSO regression were enrolled in the multivariate Cox regression model. The results showed that age [hazard ratio ( HR) = 1.021, 95% confidence interval (95% CI) was 1.018-1.024], SOFA score ( HR = 1.020, 95% CI was 1.000-1.040), SAPSⅡ score > 44 ( HR = 1.480, 95% CI was 1.340-1.634), mean arterial pressure (MAP) ≤ 75 mmHg (1 mmHg ≈ 0.133 kPa; HR = 1.120, 95% CI was 1.026-1.222), respiratory rate (RR; HR = 1.044, 95% CI was 1.034-1.055), cerebrovascular disease ( HR = 1.620, 95% CI was 1.443-1.818), malignant tumor ( HR = 1.604, 95% CI was 1.447-1.778), severe liver disease ( HR = 1.330, 95% CI was 1.157-1.530), use of vasoactive drugs within 24 hours ( HR = 1.213, 95% CI was 1.101-1.336), arterial partial pressure of oxygen (PaO 2; HR = 0.999, 95% CI was 0.998-1.000), blood lactic acid (Lac; HR = 1.066, 95% CI was 1.053-1.079), blood urea nitrogen (BUN) > 8.9 mmol/L ( HR = 1.257, 95% CI was 1.144-1.381), total bilirubin (TBil; HR = 1.023, 95% CI was 1.015-1.031), and prothrombin time (PT) > 14.5 s ( HR = 1.232, 95% CI was 1.127-1.347) were associated with the death of ICU patients with sepsis (all P < 0.05). Based on the above factors, a nomogram model was constructed, and the model validation results showed that the consistency index was 0.730. The calibration curve showed a good consistency between the predicted results of the nomogram model and observed results in the training and validation sets. ROC curve analysis showed that the area under the ROC curve (AUC) predicted by the nomogram model in the training set and the validation set for 28-day, 90-day and 1-year death risk was 0.771 (95% CI was 0.756-0.786) and 0.761 (95% CI was 0.738-0.784), 0.777 (95% CI was 0.763-0.791) and 0.765 (95% CI was 0.744-0.787), 0.677 (95% CI was 0.648-0.707) and 0.685 (95% CI was 0.641-0.728), respectively. DCA analysis showed that the nomogram model had significant net benefits in predicting 28-day, 90-day, and 1-year death risk, verifying the clinical value of the model and its good impact on actual decision-making. Conclusions:The death risk factors related to ICU patients with sepsis include age, SOFA score, SAPSⅡ score > 44, MAP ≤ 75 mmHg, RR, cerebrovascular disease, malignant tumors, severe liver disease, use of vasoactive drugs within 24 hours, PaO 2, Lac, BUN, TBil, PT > 14.5 s. The nomogram model constructed based on this can predict the death risk of ICU patients with sepsis.
ABSTRACT
Objective To assess the association between early adiposity rebound (AR) and indices of obesity and metabolic risk in 5-year-old children. Methods Based on Ma’anshan Birth Cohort Study (MABC), single live births born in Ma'anshan of Anhui province from October 2013 to April 2015 were followed for up to 5 years consecutively. As of August 2019, 720 children with continuous measurements (≥8 times) and metabolic indicators were obtained. Physical examination and laboratory tests were used to obtain information on the birth status, length/height, weight, waist circumference, body composition and metabolic indicators of children. The 2 test, F test, t-test, non-parametric test, general linear model and logistic regression model were used for statistical analysis. Results 43.5% of the children had AR≤4 years. After controlling for gender, it was found that earlier AR was associated with overweight/obesity (OR=2.71, 95%CI: 1.81~4.05), larger waist circumference (OR=1.88, 95%CI: 1.25~2.82), and body fat percentage ≥90th percentile (OR=2.09, 95%CI: 1.26~3.48). In the earlier AR group, the insulin resistance and metabolic score were higher, but the difference was not statistically significant. At 5 years of age, the prevalence of obesity and overweight was 6.0% and 12.8%, respectively. Children with overweight/obesity, larger waist circumference, higher waist-to-weight ratio and body fat percentage ≥ 90th percentile were associated with higher insulin resistance and metabolic score, and all the differences were statistically significant (all P<0.001). Conclusion Earlier AR increased the risk of overweight/obesity, larger waist circumference, and body fat percentage ≥90th percentile at age of 5 years. Each index of the commonly used measures of childhood obesity was closely related with insulin resistance and metabolic risk factors at 5 years old.
ABSTRACT
Objective:To investigate the developmental behavior of early term infants at 6 months and its difference from that of complete full-term infants.Methods:A healthy maternal and infant birth cohort in maanshan city, established in Maanshan Maternal and Child Health Hospital from June 2015 to June 2016. Birth outcomes were copied from the hospital electronic medical record system after delivery. The Chinese Ages and Stages Questionnaires was used to assess developmental behavior. The chi-square test and multivariate unconditional logistic regression model were used to analyze the differences in the behavioral development of early and full term infants.Results:The birth rate of early term infants was 24.74% (500/2 021). The detection rates of communication, gross motor, fine motor, problem solving and individual-social areas in early term infants were 2.1%, 3.2%, 6.1%, 6.3% and 2.7%, respectively. The detection rate of problem-solving area in early term infants was significantly higher than that in the full-term infants (6.3% vs. 3.7%, χ 2=5.42, P<0.05). After controlling for confounding factors, compared with full-term infants, the risk of problem-solving area in early infants was significantly increased ( OR=1.65, 95%CI:1.01-2.70, P<0.05). Conclusion:The risk of behavioral retardation in Early term infants is significantly higher than that in full-term infants, and long-term follow-up and appropriate early development promotion interventions are needed to improve their quality of life.
ABSTRACT
OBJECTIVE： To improve the method for the content determination of astragaloside Ⅳ in Xiangju granules， and to evaluate the consistency of relevant preparations with the components of original formulation， so as to provide evidence for the modern preparation of TCM compound. METHODS： HPLC-ELSD method was established for the content determination of astragaloside Ⅳ in Xiangju granules， and compared with original standard TLC scanning. Using critrinin， ferulic acid， calycosin glucoside， liquiritin， glycyrrhizic acid， rosmarinic acid， buddleoside and magnoline as control， HPLC method was used to determine the release components of self-made Xiangju granules， Xiangju capsules， Xiangju tablets in water. Fingerprint characteristics chromatogram of different Xiangju preparations and original formulation extract were compared by using Similarity Evaluation System for Chromatographic Fingerprint of TCM （2012 version）. At the same time， HPLC-ELSD method was used to determine and compare the release rate of astragaloside Ⅳ from different Xiangju preparations and original formulation extract in water. RESULTS： Established HPLC-ELSD method was specific. The linear range of astragaloside Ⅳ was 0.13-2.10 mg/mL. RSDs of precision， repeatability and stability tests were all lower than 3％ （n＝6）， and average recovery was 97.66％ （RSD＝1.01％，n＝6）. Average content of astragaloside Ⅳ by this method was 0.398 mg/g （RSD＝1.01％， n＝3）， which had better reproducibility than TLC scanning. The comparative results of characteristic fingerprints showed that the similarity among Xiangju granules， Xiangju capsules， Xiangju tablets and the original formulation dry extract powder was more than 0.850. Average release rates of astragaloside Ⅳ in Xiangju granules， Xiangju capsules， Xiangju tablets and the original formulation extract were 0.392， 0.358， 0.349， 0.389 mg， respectively. Compared with original formulation extract， there was no statistical significance in release rate of astragaloside Ⅳ in Xiangju granules （P＞0.05）， while there was statistical significance in Xiangju capsules and Xiangju tablets （P＜0.01）. CONCLU- SIONS： Established HPLC-ELSD method is accurate and feasible， and is suitable for the content determination of astragaloside Ⅳ in Xiangju granules. The main components of Xiangju granules are consistent with original formulation.

ABSTRACT
Objective To evaluate the difference of B-type natriuretic peptide(BNP)levels between patients with Non-ST elevation myocardial infraction(NSTEMI)and those with unstable angina(UA)and to ex-plore its relationship with the risk factors of major adverse cardiovascular events(MACE)and its value in progno-sis. Methods BNP levels of 110 consecutive patients with NSTE-ACS including 60 cases of NSTEMI and 50 of UA were studied and the incidence of MACE within 6 months after discharge was followed. Results(1)BNP lev-els were higher in NSTEMI group than those in UA group.(2)There were 32 patients suffering from MACE during the following-up.BNP levels were significantly higher in patients with MACE.(3)The risk of suffering from MACE was greater in NSTEMI patients than that in UA patients. Conclusions The level of blood BNP can be used in the differential diagnosis between UA and NSTEMI.Meanwhile,it correlates with the clinical severity and outcome of NSTEMI and may potentially be used as a prognostic marker for NSTEMI.
ABSTRACT
Objective With multi?center investigation, to assess the life quality of patients with maintained hemodialysis (MHD) in Liaoning Province and to explore the relationship among the mineral metabolism, the life quality of the patients with MHD, and the repeated hospitalization within the latest three years. Methods 1192 patients with hemodialysis (at least 3 months) from January to March in 2015 at ten blood purification centers in Liaoning Province were selected for the cross?————————sectional survey. The Kidney Health?related Quality of Life (HRQOL) version 1.3 was used to evaluate the MHD patients' life quality. The total length of hospitalization was divided into four groups: 0 days, 3 to 15 days, 16 to 30 days and above 30 days. Results When serum calcium value ranged from 2.1 to 2.5 mmol/L, kidney?disease component summary (KDCS), mental component summary (MCS), physical component summary (PCS) and SF?36+KDCS corresponded to a higher value (P<0.05). When serum phosphorus value ranged from 1.13 to 1.78 mmol/L, KDCS and SF?36+KDCS corresponded to a higher value (P<0.05). When the calcium phosphorus product value ranged from 40.68 to 49.94, MCS corresponded to a higher value (P<0.05). KDCS showed a linear correlation with age (P<0.001), dialysis age, serum calcium (less than or equal to 2.5 mmol/L) (P<0.05); PCS showed a linear correlation with age (P<0.001) and dialysis age (P<0.05); SF?36+KDCS showed a linear correlation with age (P<0.001), and serum calcium (less than or equal to 2.5 mmol/L) (P<0.05), while age and dialysis age were negatively correlated. The hospitalization days showed a linear correlation with age, dialysis age (P<0.001) and serum phosphorus, calcium phosphorus product value (P<0.05), while dialysis age and calcium phosphorus product value were negatively correlated. Among different groups of total hospitalization days in three years, age, hemodialysis age, serum calcium, serum phosphorus, calcium?phosphorus product value and quality of life values were all statistically significant (P<0.05). Conclusions The life quality of patients with MHD were correlated with serum calcium, phosphorus, calcium and phosphorus product value, iPTH, dialysis age and age, while age and dialysis age were of negative correlation. The total number of hospitalization days in 3 years was closely linearly correlated with age and dialysis age, significantly correlated with serum phosphorus, calcium and phosphorus product value, while dialysis age, calcium and phosphorus product value were in a negative correlation. The total number of hospitalization in 3 years was correlated with the patients' age, dialysis age, serum calcium, serum phosphorus, calcium and phosphorus product value and quality of life.
ABSTRACT
ObjectiveTo evaluate the effect of Rhubarb associated preparations (rhubarb or prescriptions of traditional Chinese medicine including rhubarb) on sepsis patients with acute gastrointestinal dysfunction (AGI).Methods The retrieval of databases from libraries including PubMed, Medline, Cochrane Central Register of Controlled Trials, CNKI, CBMdisc, Wan Fang Database, VIP database were searched to identify randomized controlled trials (RCTs) about Rhubarb associated preparations for treatment of sepsis patients with AGI from the foundation of the various databases to March 2016. And in the mean time, the references of the studies accepted were also retrieved. The retrieving and screening of literatures were performed independently by two researchers, the methodological quality and data extraction of the enrolled literatures were assessed by Jadad scale, and Cochrane Collaboration 5.3 software was used to perform Meta analyses to observe the effects of rhubarb associated preparations on gastrointestinal function score, acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ) score and 28-day mortality in sepsis patients with AGI; the bias of published literatures was evaluated by funnel plot.Results ① Finally, 16 studies involving 1 171 patients (610 in rhubarb preparation group and 561 in the control group) were identified and enrolled. 12 studies had a Jadad score ≥ 3 and 4 studies < 3. The random method was used in classification of groups in all the studies in which the intergroup baseline data being comparable was clearly indicated. The blind method was applied in 5 contained RCTs.② The results of Meta-analyses showed that rhubarb associated preparation could improve gastrointestinal function score [mean difference (MD) = -0.52, 95% confidence interval (95%CI) = -0.55 to -0.48, P < 0.000 01], reduce the APACHEⅡ score (MD = -3.66, 95%CI = -5.00 to -2.33,P < 0.000 01) and 28-day mortality [odds ratio (OR) = 0.46, 95%CI = 0.30 to 0.71,P < 0.000 01] compared with those in the control group, the differences being statistically significant. No publication bias was seen in 16 literatures containing RCTs from the funnel plot.Conclusions Compared with the control group, the rhubarb associated preparations combined with conventional theraph can significantly improve the gastrointestinal function score, reduce APACHE Ⅱ score and 28-day mortality of sepsis patients with AGI, which suggests the rhubarb associated preparations have better efficacy. In addition, the result of sensitivity analysis has not substantially changed the results of Meta-analysis.

ObjectiveThe aim of this study is to analyze the etiology and status of bone age of children with short stat-ure.MethodsAnthropological and physical examination data were retrospectively collected and studied in 2132 children with short stature in the department of endocrinology between 2009 and 2014. Growth hormone (GH) levels were determined by ar-ginine-clonidine test. Bone age was determined by CHN scoring.ResultsAmong the 2132 patients, 1333 were males and 799 were females. Mean age is 9.03 ± 3.04 years old, mean bone age is 6.81 ± 3.05 years. Of them, 324 cases (15.2%) were diagnosed complete GH deifciency, 780 cases (36.59%) were partial GH deifciency, 27cases (1.27%) were multiple pituitary hormone de-ifciency, 13 cases (1.64%) were hypothyroidism, 893 cases (41.89%) were idiopathic short stature, 19 cases (0.89%) were small for gestational age (SGA), 40 cases (1.88%) were chromosomal disorders, etc. Signiifcant difference in age and bone age was found using t test (P<0.05). Signiifcant differences in Δage were found between etiological categories using ANOVA (P=0.000). Δage was signiifcantly and negatively associated with peak GH using Pearson's correlation.ConclusionsGH deifciency is the most common cause of short stature. Bone age of children with short stature is commonly delayed. Δage was signiifcantly and negatively associated with peak GH. Multiple pituitary hormone deifciency has a signiifcant effect on bone age. The etiology of patients with short stature cannot be determined just by bone age.
ABSTRACT
<p><b>OBJECTIVE</b>To understand the dietary consumption of residents in Xiamen and the content of phthalic acid esters (PAEs) in food, and to assess the plasticizer exposure risk of diet in Xiamen.</p><p><b>METHODS</b>The survey was conducted by stratified cluster random sampling method in Xiamen from September to October in 2010. According to the Xiamen administrative division, six neighborhood communities were selected as sampling units, then 25 families were randomly chosen from each sampling units.From the above 150 families, the permanent residents over the age of six were permitted to our study. The survey included 495 residents totally. These participants' information, such as basic personal information, physical activity levels, meal frequency and the average consumption of 33 kinds of food in 13 categories were collected using questionnaires. Thirteen categories included cereal and tubers, beans, vegetables, fungi and algae, fruits, dairy products, meat, seafood, eggs, snacks, beverages, cooking oil and spices. The height and weight of residents were measured and the average daily dietary intake was calculated. Thirty-three kinds of food in 13 categories were collected in supermarkets in Xiamen. According to the annual sales ranking, the top three-five brands of each kinds of food were selected and numbered, then two or three brands were chosen by random number table method from them; three completely individual packed samples in the same batch of each brand were detected; 243 samples were included in our study.100-500 g solid samples or 100-500 ml liquid samples were collected. The content of diethyl phthalate (DEP), dibutyl phthalate (DBP), di (2-ethylhexyl) phthalate (DEHP) in food were detected by liquid chromatography mass spectrometry, which expressed by median (minimum-maximum). The exposure dose, contribution rate and risk index of PAEs were calculated by point estimation method.</p><p><b>RESULTS</b>According to the average daily dietary intake of residents in Xiamen, the top three ones in 13 categories of food were cereal and tubers (337.16 g/d, 18.21%), vegetables (309.12 g/d, 16.69%) and fruits (213.20 g/d, 11.51%). The content of DEP, DBP or DEHP among different categories of food was significantly different (χ² values were 58.05, 50.19 and 102.10, P < 0.01). Among 13 categories of food, seafood contained the most DEP (0.090 (0.000-0.324)mg/kg); cooking oil had the most DBP (0.700(0.000-2.980) mg/kg) and DEHP (5.115(0.000-24.160) mg/kg). DEP, DBP and DEHP exposure(0.19, 4.20, 18.10 µg × kg⁻¹ ×d ⁻¹)in dietary food in Xiamen were less than the reference dose(RfD) (800, 100, 20 µg × kg⁻¹ × d⁻¹) proposed by the United States Environmental Protection Agency (EPA), and the risk indexes were 0.02%, 4.20% and 90.50%, respectively. Among 13 categories of foods, seafood was the main source of DEP dietary exposure. The exposure dose and contribution rate of DEP in seafood were 0.18 µg × kg⁻¹ × d⁻¹ and 94.74%, respectively.Vegetables were the main source of DBP and DEHP dietary exposure. The exposure dose and contribution rate of DBP and DEHP were 1.48 µg × kg⁻¹ × d⁻¹, 35.24% and 6.07 µg × kg⁻¹ × d⁻¹, 33.54%, respectively.</p><p><b>CONCLUSION</b>The food consumed by residents in Xiamen was overall in a safe state, but to some extent, there still exists DEHP exposure risk in foods.</p>

Objective To investigate the necessity,safety and efficacy of transobturator tension-free vaginal tape (TVT-O) for treatment of stress urinary incontinence (SUI) during transvaginal corrective operation of pelvic organ prolapse (POP).Methods From Jan.2005 to Dec.2010,92 patients undergoing transvaginal pelvic reconstruction surgery for correction of POP concomitant TVT-O for treatment of SUI in Department of Obstetrics and Gynecology affiliated to Beijing Chaoyang Hospital as concomitant surgery group were enrolled in this retrospective study matched with 90 patients with mild SUI without SUI surgery as nonconcomitant surgery group and 120 patients without SUI as control group.Variable clinical index,clinical efficacy and complications were compared among those three groups.Results Compared with those in the other two groups,the mean age [(62 ± 11) years] was lower (P =0.007,0.038),the operation time only slightly increased (12.8 min and 12.9 min respectively) significantly in concomitant TVT-O group.The bleeding loss and the length of staying hospital after operation all exhibited no significant differences within three groups (P ＞ 0.05).The effective rate for SUI was 96.7％ (89/92) in concomitant TVT-O group,corrective operation of POP was ineffective for 74.4％ (67/90) SUI,9.2％ (11/120) patients presented new SUI in the patients without SUI preoperatively.Conclusions TVT-O is a simple,safe and effective method in the treatment of SUI,which is more suitable for performing simultaneously during the corrective operation of POP.Efficacy of SUI correction was limited in those patients undergoing only pelvic reconstructive surgery.However,a preventive anti-incontinence procedure is not recommended because of the lower incidence in POP patients without SUI preoperatively.
ABSTRACT
Objective To investigate the correlation between serum tumor necrosis factor (TNF)-α,neuron-specific enolase (NSE)and the degree of hypoxic-ischemic encephalopathy (HIE).Methods Forty-six HIE patients in acute and convalescent stage and 30 full-term newborn infant were enrolled in this study.The level of serum of TNF-α and NSE were detected.The relationship between TNF-α,NSE level and severity of HIE was analyzed.Results The level of serum TNF-α and NSE in acute stage of HIE group were (156.3 ± 28.8) ng/L and (21.5 ± 3.6) μg/L,in convalescent stage of HIE group were (80.7 ± 26.1) ng/L and (10.6 ± 1.7) μ g/L,and in control group were (76.3 ± 24.4) ng/L and (9.4 ± 1.6) μ g/L.The level of serum TNF-α and NSE in acute stage of HIE group were significantly higher than those in convalescent stage of HIE group and control group (P ＜ 0.05).The level of serum TNF-α and NSE in convalescent stage of HIE group had no significant difference compared with those in control group (P ＞ 0.05).The level of serum TNF-α and NSE in mild HIE group were (88.5 ± 25.6) ng/L and (9.7 ± 2.4) μ g/L,in moderate HIE group were (150.1 ± 16.5) ng/L and (17.8 ± 3.6) μ g/L,and in severe HIE group were (197.3 ± 30.2) ng/L and (23.6 ±4.3) μg/L.The level of TNF-αand NSE were increased with the aggravation of HIE and there had significant difference among different degree of HIE(P ＜ 0.05).The level of serum TNF-α and NSE in mild HIE group and control group had no significant difference (P ＞ 0.05),and there had significant difference between moderate HIE group,severe HIE group and control group (P ＜ 0.05).Spearman rank correlation analysis showed that the level of TNF-α and NSE had positive correlation with the degree of HIE (r =0.54,0.57,P ＜ 0.01 or ＜ 0.05).Pearson correlation analysis showed that the level of TNF-α had positive correlation with the level of NSE (r =0.46,P ＜ 0.05).Conclusions The variation of TNF-α and NSE level in HIE newborn infant is parallel to the severity of the disease,which can sensitively reflect the severity of HIE.Therefore,TNF-α and NSE may be used as vital indexes for the evaluation of the severity of HIE.
ABSTRACT
Objective To study the influences of Jianpizhidong decoction(JPZDD) on bilateral striatal amino acid neurotransmitters in mice with Tourette Syndrome (TS) disease and discuss the mechanism of JPZDD.Methods Thirty mice were injected 3,3-iminodipropionitrile (IDPN) with 350 mg· kg-1 once a day for 7 consecutive days except ten mice of the blank control group which were injected with saline.TS mice were randomly divided into three groups:TS model group,JPZDD group (the Chinese herbal group),Tiapride group (the western medicine group).The TS model group and the blank control group were gavaged with saline(0.9％)at 20 ml ·Kg-1,the Tiapride group with Tiapride at 50 mg · kg-1,and JPZDD group with JPZDD at 20 g · kg-1,respectively,once a day for six weeks.Then behavioral recordings were conducted,and the content of glumatic acid (Glu) and γ-aminobutyric acid (GABA) in the bilateral striatum of the mice were detected by using HPLC.Results Behavioral recording indicated that there were significant differences in the Chinese herbal group and the Tiapride group before(1.90 ± 1.80,2.05 ± 1.40) and after(1.15 ± 1.67,1.00 ± 1.08) treatment (P ＜ 0.05).The content of Glu and GABA in TS model group (1858.33 ± 203.00,261.24 ± 47.31) and Tiapride group (1744.53 ± 234.01,258.57 ± 57.64) were higher compared with the blank control group (P ＜ 0.05),and the content of Glu in JPZDD was significantly higher than that in TS model group.There was no statistical difference between other groups(P＞0.05).The ratio of Glu and GABA were lower in the JPZDD,the Tiapride and the model groups than that in the blank control group,but there were no statistical differences between these groups (P＞ 0.05).Conclusion JPZDD can regulate the content of Glu and GABA in the striatum,and keep the dynamic equilibrium,which might be its pharmacodynamic mechanisms for treating TS.
