Objective To observe the effects of Jieyu-Chufan capsule(JCC) on the behavior and the monoamine neurotransmitter content of cerebral in depression mouse model and explore its mechanism. Methods The ICR male mouse were randomly divided into seven groups according to their weights(the model group, the low, middle and high doses group, Baiyoujie group, the amitriptyline group, the normal control group). The low, middle and high doses group were given JCC with 1.250, 2.500, 5.000 g/kg separately by intragastric administration. Baiyoujie group was given 0.014 g/kg Baiyoujie by gavage. The amitriptyline group was given 0.050 g/kg amitriptyline by gavage. The model group and the normal control group received the same volume of distilled water intragastrically. The drugs were administrated once a day. The brepharoptosis and movement conditions of mouse were observed after 22 days. The monoamine neurotransmitter content of each group was measured after 25 days. Results Compared to the model group, the number of mouse with brepharoptosis decreased in the high dose group after 1, 2, 6 hour with reserpine injection (P<0.05 or P<0.01);the number of mouse came out from the circle increased after 4 hours with reserpine injection (P<0.05 or P<0.01);the content of NA (880.45 ± 428.81 ng/g, 875.98 ± 449.33 ng/g vs. 299.92 ± 267.08 ng/g) and DA (2 305.99 ± 530.37 ng/g, 2 169.99 ± 278.19 ng/g vs. 1 439.34 ± 357.33 ng/g) in the middle and high dose group increased (P<0.01);the content of 5-HT (781.43 ± 135.10 ng/g vs. 492.01 ± 192.80 ng/g) in the middle group increased (P<0.01). Conclusions JCC showed an antidepression influence in depression mouse model induced by reserpine. The mechanism may be related to regulating the level of monoamine neurotransmitter in the nervous centralis .

Objective To review the clinical treatment and outcome of ultrasonographic soft markers in prenatal diagnostics. Methods This study recruited 268 pregnant women who underwent prenatal diagnostics in our hospital between Jun 2005 to Mar 2009. Fetuses were followed up postnatally. The outcome and chromosomal abnormalities of ultrasonographic soft markers were assessed. Results Of 268 cases consulted, 29 cases were missed (10.8%), 34 cases (12.7%) chose abortion, and 205 cases (76.5%) delivered. The top four most common delivered isolated markers were thickened nuchal fold, mild pyelectasis, echogenic bowel and rhizomelic limb shortening. Mild ventriculomegals had the highest aborted rate (17.2%). Six chromosomal structural abnormalities and one 21-trisome were detected in 59 fetuses who received chromosomal examination. Conclusions Ultrasonographic soft markers are risks to both fetal trisome and chromosomal structural abnormalities. Owing to extinction in most cases, consultant should be strengthed to avoid unnecessary invasive examination and abortion.

Objective:To explore the metabolic regulations of different Traditional Chinese Medicine (TCM) syndromes in the diabetic patients with high risk for foot ulceration.Methods:Based on gas chromatography-mass spectrometer and multi-dimensional data processing methods, the metabolomics analysis was used to compare the serum metabolites profile of healthy people (32 cases) and the high-risk foot patients in Cold and Blood Stagnation syndrome (44 cases), Heat-toxin hurting Yin syndrome (54 cases), and Qi-Blood deficiency syndrome (33 cases), who were hospitalized at Shanghai TCM-Integrated Hospital from Apirl to December, 2018.Results:This study suggested that compared with healthy people, the diabetic patients with high risk for foot ulceration showed significantly lower serum level of urea [(2.41 ± 1.57)×10 5vs. (3.32 ± 2.10)×10 5], L-leucine [(4.94 ± 3.15)×10 5vs. (6.39 ± 3.57)×10 5], aspartic acid [(3.94 ± 4.48)×10 5vs. (9.62 ± 6.93)×10 5], 9H-purine [(1.74 ± 1.95)×10 5vs. (3.34 ± 2.23)×10 5] ( P<0.05 or P<0.01), while higher level of d-Glucose [(3.72 ± 1.71)×10 5vs. (2.21 ± 1.32)×10 5] and d-glucopyranose [(3.32 ± 2.10)×10 5vs. (1.35 ± 1.43)×10 5] ( P<0.01). Energy metabolism, amino acid metabolism and sugar metabolism were mainly involved. the content of L-tyrosine in the group of patients with Cold and Blood Stagnation syndromewas significantly higher than that in healthy people. The urea, purine, leucine, aspartic acidcontent in patients of Heat-toxin hurting Yin syndrome were significantly lower than that in healthy people. The purine content in patients of Qi and Blood Deficiency Syndrome was significantly lower than that in healthy people. Compared with the syndrome of Heat-toxin hurting Yin syndrome, patients in Cold and Blood Stagnation syndrome showed a significantly higher content of beta-1-galactopyranoside and butanoic acid. Compared to the Qi-Blood deficiency syndrome, serum urea level in patients of Heat-toxin hurting Yin syndrome was significantly higher than those in the patients of other two TCM syndromes. Conclusions:The serum metabolomics profiling differentiate three TCM-syndrome in high-risk DF patients, which can provide objective basis for clinical TCM syndrome differentiation and treatment of high-risk diabetic foot patients.

Objective To explore the level of expression, clinical signiifcance of sB 7-H 3 in the bronchoalveolar lavage lfuid (BALF) of refractory Mycoplasma pneumoniae (MP) pneumonia (RMPP) in children and the relationship between sB7-H3 and various cytokines. Methods The BALF of forty-three hospitalized children with RMPP (RMPP group) were collected for the diagnosis and treatment. Thirteen cases were lavaged only once and the other thirty cases had collected the BALF twice. The BALF of iffteen hospitalized children with bronchial foreign body were collected as control group. The expression levels of sB 7-H 3 , IL-1β, IL-2 and IL-36 in the BALF were detected by enzyme-linked immunosorbent assay. The expression levels of sB 7-H 3 , IL-1β, IL-2 and IL-36 in the BALF at the acute phase were compared with control group and the group after treatment. Analyzed the correlation between the level of sB 7-H 3 and IL-1β, IL-2 , IL-36 in the BALF of RMPP children at acute stage. Results The levels of sB 7-H 3 , IL-1β and IL-36 in the BALF of the ifrst lavage group were higher than those of single lavage group and control group (all P<0 . 05 ). The levels of sB 7-H 3 , IL-1β, IL-2 and IL-36 in the BALF of single lavage group were higher than those of control group (all P<0 . 05 ). The levels of sB 7-H 3 , IL-1β, IL-2 and IL-36 in the BALF of the second lavage group were lower than those of the ifrst lavage group (all P<0 . 05 ).The levels of sB 7-H 3 , IL-2 in the BALF of the second lavage group were higher than those in the control group (both P<0 . 05 ), but the levels of IL-1β, IL-36 in the BALF showed no difference between the second lavage group and the control group (both P>0 . 05 ). The levels of sB 7-H 3 had positive correlation with the levels of IL-1β, IL-2 and IL-36 (all P<0 . 001 ). Conclusions sB 7-H 3 may control the secretion of IL-1β, IL-2 and IL-36 , and participate in immune response and lung injury after MP infection, which may lead to occurrence and development of RMPP.
