The method of reinforcement and elimination are frequently used in TCM therapy on malignant tumor,as mediation method is seldom used.But Dr.CHEN Yi realizes that spirit being invalid is the key to the invasion of malignant tumor,and depression is the key to the pathogenesis of tumor,qi stagnation and blood stasis is its main characteristic.Under the guidance of the spirit-regulating and depression-relieving,on the base of mediation therapy,Dr.CHEN Yi uses Xiaoyao Powder,combined with the therapies of activating blood,dispelling dampness,resolving phlegm,purging the pathogenic fire,promoting digestion,in treating malignant tumor to dredge meridians,make qi and blood unobstructed,eliminate the stagnation,and it has gotten satisfactory results which include improving the patients’life quality,constraining tumor’s development,prolonging patients’ survival time.This text is a brief instruction to the application principle and theoretic basis of CHEN Yi’s law of regulating spirit and relieving depression in malignant tumor therapy.

Objective To explore the expression of galectin-3 in human gastric carcinoma tissues and to investigate its clinincal significances.Methods Immunohistochemistry method was used to detect the expression of galectin-3 in 52 pairs of specimens of gastric carcinoma tissues,33 atypical hypcrplasia of gastric tissues and 20 gastritis tissues.Expression levels of galectin-3 in different tissues were compared and analyzed.The relationship between expression levels and clinical parameters was investigated.Results The positive rates of galectin-3 were 94.2 ％ (49/52),80.0 ％ (16/20) and 33.3 ％ (11/30).The positive rates of galectin-3 were higher in gastric carcinoma than those in atypical hyperplasia and gastritis (Z =2.181,6.160,3.611,all P ＜ 0.05).The expression levels of galectin-3 in lymph node metastasis gastric carcinoma,poorly differentiated gastric carcinoma were 100 ％ (22/22),100 ％ (45/45) respectively.Galectin-3 expression in patients without lymph node metastasis,high differentiation in gastric carcinoma were 78.6 ％ (27/30),57.1％ (4/7)respectively.The expression levels of galectin-3 were correlated with metastasis and differentiation,with higher expressions in the cases with metastatic lymph nodes (Z =12.463,P ＜ 0.05) and in poor differentiation tissues (Z =3.245,P ＜ 0.05).Conclusion Galectin-3 is overexpressed in gastric carcinoma tissues,indicating that both of them may play roles in the pathogenesis of gastric carcinoma.The overexpression of galectin-3 is correlated with metastatic lymph nodes and poor differentiation,indicating that galectin-3 may be prognostic indicator of gastric carcinoma.

Objective To explore the dynamic expression of a new phospholipid phosphatase, plasticity related gene 1 ( PRG-1 ) in cerebral cortex following recurrent neonatal seizures.Methods A seizure was induced by inhalant flurothyl daily in neonatal Sprague-Dawley rats from postnatal day 6 (P6).Rats were assigned into the recurrent-seizure group (seizures induced in six consecutive days) and the control group.At 3 h,12 h,48 h,14d after the last convulsion,PRG-1 protein level in cerebral cortex was detected by western blot method.Results At 3 h, 12 h,48 h, 14d after the last convulsion in control group, the expression of PRG-1 in cerebral cortex respectively was 1.363 ± 0.742,1.278 ± 0.687 ,0.763 ± 0.374,1.004 ± 0.113, in experimental group , the expression of PRG-1 in cerebral cortex respectively was 1.818 ± 1.093,1.562 ± 0.782,1.024 ± 0.510,1.378 ± 0.279.At 3 h, 12 h,48 h, the expression of PRG-1 in cerebral cortex was not significantly different between the experimental and control group( t = 0.843,0.668,1.011 ,all P ＞ 0.05 ).However, at 14 d, the level of PRG-1 protein in cerebral cortex of experimental group was significantly higher than that of control ( t = 3.041, P ＜ 0.05 ).Conclusion The up-regulated expression of PRG-1 in cerebral cortex may be associated with the recurrent neonatal seizure-induced brain damage.

Objective To explore change of RBC[Ca2+]i levels in neonates with hypoxic-ischemic encephalopathy(HIE)and the influence of nimodipine on RBC[Ca2+]i and its clinical significance.Methods Fifty-eight neonates with moderate and severe HIE were randomly divided into 2 groups including routine treatment group(n=28)and nimodipine group(n=30),and 20 healthy full-term neonates were selected as healthy control group.Based on the routine treatment,nimodipine[2 mg,0.5-1.0 ?g/(kg?min)] was given intravenously in the nimodipine group for 7-10 days.Blood samples were collected before and after treatment for 72 hours and 10-14 days,respectively.The levels of RBC[Ca2+]i were measured by Fura-2 pentakis(acetoxymethyl)ester[Fura-2/AM].The results were analyzed by SPSS 10.0 software.Results 1.The levels of RBC[Ca2+]i in neonates with HIE were significantly higher than those in healthy control group[(2.83?0.36)mmol/L vs(2.15?0.18)mmol/L,P

Objective To investigate the involvement of apoptosis in the lesions of patients with psoriasis. Methods The apoptosis was detected with terminal deoxynucleotidyl transferase mediated dUTP biotin nick end labeling (TUNEL), and the expression of p53, PCNA and apoptosis suppressing protein bcl 2 was assessed with immunoperoxidase technique in psoriatic lesions and normal skin. Results A large number of keratinocytes showing biochemical and morphologic features of cells undergoing apoptosis were observed in all the suprabasal layers of the psoriatic epidermis. The plaques from all patients analysed showed marked increase in the number of PCNA positive cells in the middle and basal keratinocytes, and a dramatic reduction in the number of bcl 2 positive cells in the basal cell layer. Conclusion The increased apoptosis of keratinocytes in the lesions of psoriasis might be a homeostatic mechanism to the hyperplasia of cells.

Objective In this study, we tested the ability of platelet-rich plasma to enhance bone consolidation during distraction osteogenesis in a rabbit model of leg lengthening. Methods Twenty New Zealand white rabbits, which were randomly divided into two groups, the PRP treated group and the control group (n=10). Osteotomy will be made under the tibiofibular junction of left tibia, and 1cm tibia shaft will be removed through a second osteotomy. The tibia will be shorted for 1cm and then fixed by Orthfix unilateral lengthener with 4 pins. Lengthening will start 7 days after the osteotomy surgery, at a rate of 1.0 mm/day, in two steps, for 10 days. 500ul PRP were respectively injected into the distraction gaps at the end of the 10-day lengthening and at 10 days before termination. No management in the control group. The animals were terminated at day 20 following final lengthening. Serial radiographs will be taken at the day of surgery, day 12, day 17, day 27, day 37, using a C-arm radiography system. The excised bone specimens were scanned by X-ray and Micro-CT, and the bone mineral content(BMC) and the bone mineral density(BMD) of the regenerates were calculated and compared. Results The regenerate of PRP treated group was significantly better than the control group. The X-ray figures showed that the regenerate was significantly more than the control group. The figures of micro-CT 3D reconstruction showed that the growth and remodel of the regenerate in PRP treated group was better than the control group. Micro-CT examination of regenerates demonstrated a significantly greater bone mineral content(BMC) and the bone mineral density(BMD) in the PRP treated group compared to the control group(P

Objective:To determine the effects of parathyroid hormone(PTH) upon dentinogenesis in rat tooth. Methods:15 SD rats aged 42 d were evenly divided into 3 groups.In the groups of control,PTT and PTX,shamoperatoin,parathyroid autotransplantation and parathyroidectomy were conducted respectively.After operation serum Ca 2+ was weekly measured with methylthymol method.30 d after operation dentinogenesis was observed with HE staining and light microscopy.Results:30 d after operation,serum Ca 2+ concentration in PTX group was lower than that in control and PTT groups(P

Objective To investigate the results of surgical treatment of atlantoaxial instability through posterior approach. Methods Seventy eight patients with atlantoaxial instability were used for this collective review, the patients included 38 with unstable odontoid fractures,15 with os odontoideum,8 with a disrupted transverse ligament, 6 with C1,2 tumor,6 with congenital occipitocervical abnormalities,5 with old Jefferson fractures. There were 57 males and 21 females. The mean age of the patients was 42 years(range, 3-78 years). All patients were treated by operation. Thirty seven patients were operated upon by atlantoaxial arthrodesis using wire fixation with autologous bone grafts. Nine were treated by C1,2 posterior wiring fixation and atlantoaxial facet screw fixation. Nine were operated on by atlantoaxial arthrodesis using Apofix interlaminar clamping with autologous bone grafts. Occipitocervical fusion was performed in 32 patients, arthrodesis simple with autologous bone grafts and external fixation was done in 11 patients. CD-Cervical fixation was used in 11 patients. Cervifix fixation was used in 10 patients. Results The patients were followed up for an average of 38.4 months(range, 6-216 months). Solid arthrodesis was obtained in 75 patients and non union in 3 cases. All the non union cases occurred after occipitocervical fusion. Conclusion Posterior fusion is recommended for atlantoaxial instability due to traumatic fracture or ligament disruption, tumor, inflammatory, skeletal dysplasias, congenital abnormalities. It is emphasized that adequately controlling atlantoaxial motion, meticulously preparing the fusion bed are the important measures for successful operation.
