OBJECTIVETo observe the effect of Ningdong Granule (NG) on serum levels of interleukin-12 (IL-12) and tumor necrosis factor-alpha (TNF-alpha) of children patients with Tourette's syndrome (TS).

METHODSTotally 90 TS children patients were randomly assigned to the NG group, the NG + Tiapride group (abbreviated as the combined treatment group), and the Tiapride group, 30 in each group. Besides,another 30 healthy children were recruited as the healthy control group. Patients in the NG group were treated with NG (consisting of all gastrodia rhizome, Codonopsis pilosula, Ophiopogon japonicus, white peony root, Rhinocerotidae, oyster, earthworm, licorice root, etc.), one dose daily, administered by dissolving it in boiled water, taken in two portions in the morning and in the evening respectively. Patients in the Tiapride group took Tiapride Tablet, 50 -100 mg each time, twice daily. The dosage was adjusted according to individual difference and changes of pathogenic conditions. The maximal dosage was 300 mg per day. Those in the combined treatment group were treated with equal dose of NG and Tiapride Tablet in combination. The treatment course was 3 months for all. Changes of pathogenic condition before and after treatment were assessed by Yale global tic severity scale (YGTSS). Serum levels of IL-12 and TNF-alpha were detected by enzyme-labeled immunosorbent assay (ELISA) before and after treatment.

RESULTS(1) The total effective rate of the NG group, the combined treatment group, and the Tiapride group was 79.3%, 83.3%, and 67.9%, respectively. It was the lowest in the Tiapride group (P < 0.05). It was significantly higher in the combined treatment group than in the NG group (P < 0.05). (2) The post-treatment YGTSS score was obviously lower in each group after treatment than before treatment (P < 0.05). The posttreatment YGTSS score was obviously lower in the NG group and the combined treatment group than in the Tiapride group (P < 0.05), but with no statistical difference between the fromer two groups (P > 0.05).(3) Compared with the healthy control group before treatment, serum levels of IL-12 and TNF-alpha (pg/mL) were 124.95 +/- 22.78 and 209.52 +/- 21.69 in the NG group, 126.14 +/- 25.65 and 208.97 +/- 22.46 in the combined treatment group, 123.00 +/- 24.26 and 205.10 +/- 26.16 in the Tiapride group, being higher than those in the healthy control group (64.56 +/- 27.59 and 78.13 +/- 33.42; P < 0.05). After treatment, serum levels of of IL-12 and TNF-alpha were 104.67 +/- 16.84 and 183.01 +/- 24.95 in the NG group, 109.04 +/- 16.81 and 179.87 +/- 23.45 in the combined treatment group, significantly lower than before treatment (P < 0.05). But there was no statistical difference in serum levels of IL-12 or TNF-alpha in the Tiapride group between before treatment (123.00 +/- 24.26 and 205.10 +/- 26.16) and after treatment (117.75 +/- 16.79 and 199.76 +/- 33.21; P > 0.05).

CONCLUSIONNG could modulate abnormal serum levels of IL-12 and TNF-alpha in TS children patients, which might be one of its pharmacodynamic mechanisms for treating TS.

OBJECTIVEThis study aims to assess and compare the prevalence of Porphyromonas endodontalis (P. endodontalis) in root canals associated with primary and secondary endodontic infections by using 16s rDNA PCR and real-time fluorescence quantitative polymerase chain reaction (RTFQ-PCR).

METHODSA total of 120 adult patients with one radiographically documented periapical lesion were included. Sixty teeth presented with primary endodontic infections and 60 with secondary endodontic infections requiring retreatment. P. endodontalis was identified by using 16s rDNA PCR techniques. The positive DNA expression of P. endodontalis in two types of infected root canals were quantitatively compared by using SYBR GREEN I RTFQ-PCR.

RESULTSThe prevalence of P. endodontalis in the root canals with primary endodontic infections was significantly higher than that in root canals with secondary endodontic infections (P = 0.001). However, RTFQ-PCR results showed no significant difference in DNA expression quantities between the primary and secondary endodontic infections root canals (P = 0.303).

CONCLUSIONP. endodontalis is more highly associated with root canals having primary endodontic infections, although P. endodontalis colonize in both root canals with primary and secondary chronic apical periodontitis.

One of the challenges in andrology nowadays is the diagnosis and treatment of external genital abnormalities and defects along with the consequent voiding, sexual, and reproductive dysfunctions, for which no guidelines are yet available. Hitherto, surgical repair and reconstruction are efficient for these diseases. The key to these operations is to individualize surgical strategies according to the specific local lesion and dysfunction, usually involving flap and graft techniques. This article presents our experience in the surgical treatment of penile and scrotal abnormalities and defects with urological and andrological techniques and microsurgical strategies, focusing on the external repair and functional reconstruction. Satisfactory treatment outcomes pivot on a precise evaluation of the disease, a rational design of surgical procedures, and an earnest communication with the patient. Some cases are rather complicated and challenging, usually with complications, and therefore deserve further researches for more effective treatment strategies in clinical practice.

Objective To explore the modulatory effect of 5-HT2A receptors on the discharge activities of inspiratory neurons in medial region of nucleus retrofacialis of neonatal rats. Methods Experiments were performed in vitro brainstem slice preparations from neonatal rats. These preparations included the medial region of nucleus retrofacialis with the hypoglossal nerve rootlets retained. The rhythmic discharges of the inspiratory neurons and activities of the hypoglossal nerve rootlets were simultaneously recorded by using microelectrodes and suction electrodes, respectively. Roles of 5-HT2A receptors in modulation of the discharge activities of inspiratory neurons were investigated by administration of the 5-HT2A receptor agonist 1-(2,5-dimethoxy-4-iodopbenyl)-2-aminopropane (DOI), and its specific antagonist ketanserine dissolved in modified Kreb's solution for perfused slices. Results In DOI group, the inspiratory time (TI) was (0.864±0.07)s, expiratory time (TE) was (10.78±1.06)s, respiratory cycle (RC) was (11.79±1.64)s, integral amplitude (IA) was (357.98±37.21)(μV·s) and the peak discharge frequency (PF) was (37.83±3.66)Hz. In control group, they were (0.68±0.06)s, (13.89±2.14)s, (14.77±1.92)s, (273.57±24.39)(μV·s), and (29.92±4.50)Hz, there were significant differences between the 2 groups (Pa<0.01). In ketanserine group, TI was (0.55±0.07)s, TE and RC were (18.43±3.28)s and (20.17+2.91)s respectively, IA and PF were (214.37±33.52)(μV·s) and (22.17±3.92)Hz, there were significant differences between ketanserine group and DOI, control group (Pa<0.01).
