OBJECTIVETo evaluate efficacies of three commonly used oral drugs including Berbamine Hydrochloride Tablet (B), Qijiao Shengbai Capsule (Q), and Leucogen Tablet (L) (by single drug, two drugs or three drugs) combined with granulocyte colony-stimulating factor (G-CSF) for treat ment of chemotherapy related leukocytopenia in mice.

METHODSTotally 156 Kunming male mice were divided into the normal control group (A, n=24), the model group (B, n=24), the G-CSF group (C, n =24), the G-CSF+Q group (D, n=12), G-CSF+ B (E, n=12), the G-CSF+L group (F, n=12), the G-CSF + Q + B group (G, n=12), the G-CSF + Q + L group (H, n=12), the G-CSF + L + B group (I, n=12), and the G-CSF + L + Q + B (J, n=12). Mouse models of chemotherapy related leukocytopenia were established by intraperitoneal injection of cyclophosphamide (CTX). A G-CSF group was set up as a positive control. Mice were treated by a single oral drug, a single oral drug combined with G-CSF, and two or three drugs combined with G-CSF respectively, and the death rate calculated. Hemocytes [such as white blood cells (WBC) and its classification, red blood cells (RBC), platelet (PLT), hemoglobin (Hb)] were calculated by hematology analyzer. Mice were anatomized and important organs weighed. Organ indices were calculated.

RESULTSThere was no statistical difference in the mortality rate among all groups (P > 0.05). Compared with Group B, WBC was elevated in all other groups (P < 0.01). WBC and PLT were elevated most in Group J, Hb and RBC were also increased at the same time (P < 0.05, P < 0. 01). Compared with Group B, RBC increased in Group E, F, G, I, and J (P < 0.01); Hb obviously increased in Group C, E, F, H, I, and J (P<0.01). Compared with Group B and D, the promotion of erythroid hematopoiesis by G-CSF could be elevated in any group contained drug B and L (P < 0.05, P < 0.01). The spleen index of model mice could be significantly improved in Group C, D, and G (P < 0.01). The thymus index of model mice could be significantly improved in Group H (P < 0.05).

CONCLUSIONSThe best scheme to treat mice with chemotherapy related leukopenia or decreased three blood series was to administrate three commonly oral drugs combined with G-CSF. Authors speculated that G-CSF and Q might have a certain effect on CTX induced immune inhibition.

OBJECTIVETo observe the effect of transcutaneous acupoint electrical stimulation (TAES) combined dexmedetomidine on hemodynamic of intracranial aneurysmal subarachnoid hemorrhage patients undergoing intervention, and their protection for brain Injury.

METHODSTotally 108 intracranial aneurysmal subarachnoid hemorrhage patients undergoing intervention were randomly assigned to the electroacupuncture (EA) group and the control group according to random digit table, 54 in each group. All patients were anesthetized with dexmedetomidine. Patients in the EA group were needled at bilateral Neiguan (PC6), Lieque (LU7), and Yunmen (LU2). Parameter setting was as follows: The dilatational wave at 1. 5 Hz, strength 2 - 4 mA, 30 min. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), and heart rate (HR) were compared between the two groups immediately after entry into the room (T0), after administration (T1), intubating (T2), resuscitation (T3), extubation (T4), and leaving the operating room (T5). Levels of S100β protein (S100β) and neuron specific enolase (NSE) were compared between the two groups at T0, immediately after surgery (T6), 6 h after operation (T7), 12 h after operation (T8), and 24 h after operation (T9).

RESULTSCompared with the same group at T0, SBP, DBP, MAP, and HR were significantly reduced in the two groups at T1-T5(P <0. 05), serum levels of S100β and NSE in the two groups were significantly increased at T6-T9 (P<0. 05). Compared with the control group at T1 - T5, SBP, DBP, MAP, and HR decreased in the EA group (P <0. 05). Compared with the control group at T6-T9, serum levels of S100β and NSE decreased in the EA group (P <0. 05).

CONCLUSIONTAES combined dexmedetomidine could effectively maintain stable hemodynamics of intracranial aneurysmal subarachnoid hemorrhage patients undergoing intervention, and regulate their serum levels of S100β and NSE.

OBJECTIVETo discuss the effect of calcitonin gene-related peptides (CGRP) on epithelial cadherin (E-cd) expression in human bronchial epithelial cells (HBECs) in vitro.

METHODSThe effect of CGRP on E-cd protein and mRNA expression in both normal and O3-challenged HBECs were determined by immunocytochemistry and RT-PCR. The signal transduction pathways of CGRP were observed by using protein kinase C(PKC) inhibitor (H-7), calmodulin(CaM) inhibitor (W-7) and PKA inhibitor (H-89).

RESULTSCGRP increased E-cd mRNA and protein expressions of normal and O3-challenged HBECs in a dose-dependent manner. CGRP had no effect on cytoplasm E-cd expression. Pre-treatment with H-89, H-7 and W-7, the up-regulatory effect of CGRP on E-cd expression was partly abolished.

CONCLUSIONCGRP increased in cytomembrane E-cd expression of normal and O3-challenged HBECs in a dose-dependent manner. E-cd expression on HBECs was strengthened by CGRP via PKA, PKC and CaM pathways.

Objective To evaluate the development of the sphincter muscle complex(SMC)and defecation function in pediatric patients with congenital anorectal malformations(ARM).Methods A total of 64 children underwent MRI,among whom 39 were patients with ARM,and the others were patients without ARM undergoing MRI because of other dieases.The dimensions of the SMC in different planes were evaluated with different sequences and coils.The relationship between the SMC development and the defecation function was investigated.Results In control group,the absolute value of SMC width was (3.63?0.22)mm,which had a high correlation with age(r=0.998,P0.05).The SMCs in intermediate ARM patients[muscle index(MI)=0.47?0.05]and low ARM patients(MI=0.49? 0.05)were well developed.The SMCs in a portion of patients with high ARM(MI=0.28?0.06)were poorly developed,when MI≤0.18,anorectal contraction pressurewas significantly lower(t=3.55, P0.18[(0.85?0.20)vs(2.24?1.02)kPa].The length of anal canal with high-pressure[(10.88?3.64)vs(20.26?4.34)mm]was shorter(t=5.18,P0.18,the anorectal angle was less than 90 degrees,and normal continent function was found in 21 of 23 cases(91%).Conclusion MRI can be employed to evaluate the development of SMC in patients with ARM,MI was an objective criteria to evaluate the development of SMC.When MI≤0.18, maldevelopment of SMC will be highly suspected.

OBJECTIVETo evaluate the short- and medium-term efficacy, complications, and anti-coagulation therapies related to transcatheter closure (TCC) of coronary artery fistula (CAF) in children.

METHODSWe conducted a retrospective review of the medical records of 12 children with CAF who underwent TCC between January 2006 and January 2014, focusing on details such as preoperative, radiographic, and postoperative follow-up data, to record closure methods for CAF, anti-coagulation therapies, postoperative complications, and results of auxiliary examinations.

RESULTSAmong the 12 cases who underwent successful TCC and whose age was 1-158 months, four patients had proximal/medium-sized CAF, five had proximal/large CAF, and three had distal/medium-sized CAF. The mean period of postoperative follow-up was 3.5±2.4 years. Eleven patients took aspirin for 6 months post closure, and one took it for 18 months. Neither coronary thrombosis nor interventional complications were found. Left ventricular ejection fraction, cardiothoracic ratio, pulmonary artery pressure, and the diameters of coronary artery lesions decreased post TCC.

CONCLUSIONSTCC is feasible and safe in proximal and distal/medium-sized CAF patients. Postoperative anti-coagulation with aspirin may prevent short- and medium-term thrombosis, but treatment course and safety need to be investigated by further follow-ups.

OBJECTIVETo evaluate the role of lung lobectomy in the patients of tumor with lung metastases.

METHODSA total of 45 cases of trophoblastic tumor with pulmonary metastases treated by lung lobectomy from 1985-2002 at PUMC hospital was retrospectively analyzed. Seven cases were diagnosed as invasive mole and thirty-eight as choriocarcinoma.

RESULTSLung lobectomy was performed in all of these patients after several courses of chemotherapy. Seven cases of invasive mole reached complete remission. Eleven cases of choriocarcinoma with stage IIIa had received average 13 courses of chemotherapy, 10 of them reached complete remission. Seventeen cases of choriocarcinoma with stage IIIb had received average 14.3 courses of chemotherapy, 11 of them reached complete remission. Ten cases of choriocarcinoma with stage IV had received average 15 courses of chemotherapy, six of them reached complete remission. In the 45 patients, histologic examination disclosed haemorrhagic necrotic tissue in 27 patients, 17 of them reached complete remission (63%). Histologic examination also revealed fibrosis around the focus in 16 patients, 14 of them reached complete remission (88%). Tuberculosis was found in 2 patients.

CONCLUSIONSAlthough the development of effective chemotherapy has resulted in improved survival of patients with gestational trophoblastic tumor, lung lobectomy remains an important adjunct treatment in a selected subset of patients. Pathological examinations can help to estimate the prognosis.

The major antigen region of E2 gene of Hog Cholera Prevalent Strain (Guangxi Yuling Strain) and Chinese Hog Cholera Lapinised Virus (C-strain) derived from hog and rabbit spleen tissue, was amplified by reverse transcription polymerase chain reaction(RT-PCR) and the nested Polymerase Chain Reaction (nPCR). After the amplified fragments were cloned into the expression vector pPROEX-HTb, the recombinant plasmids pPROEX-GXYL and pPROEX-C were obtained. The insert position, the size and the reading frame were right by PCR, restriction digestion and the sequence analysis. SDS-PAGE indicated that both of the reciepient germs transducted and induced by the recombinant plasmids pPROEX-GXYL and pPROEX-C could express the major antigen region of E2 gene. Western-blot indicated that the expressed antigen protein could be recognized by the positive serum of CSFV.
