Combined with the five Zang Yin-Yang theory, to discuss the spinal marrow and cerebral Yin Yang state. As the internal organs, we believe that the spinal marrow and cerebral are substantial Yin and functional Yang. Further we can diagnose and treat the cerebral and spinal marrow injury related diseases. In the clinical therapy of acute and chronic cerebral and spinal marrow diseases, we should maintain the substantial Yin by avoiding injury, preventing spinal degeneration and maintaining the blood supply; and we should adjusting the functional Yang by nourishing the blood and promoting blood circulation, calming the liver to stop the wind, keep Yin and Weiqi in balance, tonifying the spleen and kidney etc. From the author's experience ,the patient with acute cerebral and spinal marrow injury diseases should be treated by regulating lung, liver, spleen and kidney to remove the wet water and purge the fire;the patient with chronic cerebral and spinal marrow injury diseases should be treated by regulating heart, liver, spleen and kidney to enhance Yang and nourish Yin.

Objective To establish a platinum resistance nude mice model of epithelial ovarian cancer (EOC) and investigate its resistance to cisplatin (DDP) biological characteristics, so as to provide evidences for exploring chemoresistence mechanisms and screening for reversal targets in vivo micro-environment. Methods The resistance model was produced by repeating a crossover subcutaneous injection of human ovarian cancer SKOV3 cells labelled green fluorescent protein(GFP) and transplatation of tumor fragment into nude mice. Two kinds of cancer cell lines of SKOV3/DDPⅠand SKOV3/DDPⅡwere induced with acquired resistence to DDP. The chemosensitivities of EOC cells to DDP were tested and half maximal inhibitory concentration(IC50) was measured by methyl thiazolyl tetrazolium (MTT) and flow cytometry (FCS). Dynamic analysis among the concentration of DDP treatment and cell apoptosis, cell cycle phase distribution and intracellular DDP concentration. The expression of PTEN, STAT5, XIAP, BRCA1 and MDR1 were examined by real time quantitative reverser transcription PCR (qRT-PCR) in vivo. Results IC50 value of cisplatin for SKOV3/DDPⅡ were 2.83 ± 0.12 and 3.82 ± 0.19 folds than those for SKOV3/GFP by MTT and flow cytometry, separately. SKOV3/DDPⅠwere 2.20±0.16 and 3.40±0.20 folds. The apoptosis rate of SKOV3/DDPⅡ and SKOV3/DDPⅠ were decreased significantly at 29.7 and 39.6μmol/L DDP when treatment for 36 hours,which were lower than that of SKOV3/GFP cells [(57.0±1.4)%vs (37.6 ± 4.36)%vs (83.1 ± 2.71)%,P=0.024;(74.4 ± 2.3)%vs (50.5 ± 3.4)%vs (87.4 ± 4.0)%,P=0.001]. SKOV3/DDPⅠ and SKOV3/DDPⅡ was positively related with cisplatin processing time. Intracellular DDP accumulation of SKOV3/DDPⅡand SKOV3/DDPⅠwere lower than SKOV3-GFP in dynamic processes(P<0.05). Besides intracellular DDP accumulation of SKOV3/DDPⅡ also lower than SKOV3/DDPⅠin dynamic processes (P<0.05). Transplanted tumor of SKOV3/GFP appeared organelle degradation and nuclear membrane imcompleted after five times DDP injection with concentration of 4 mg/kg. SKOV3/DDPⅡand SKOV3/DDPⅠdid not generate these phenomenon untill eighth DDP injections with concentration of 4 mg/kg. STAT5 and BRCA1 of SKOV3/DDPⅡwere increased with DDP treatment at concentration of 4 mg/kg. Expression of XIAP from SKOV3/DDPⅡwas positive correlated with injection times. STAT5,XIAP and BRCA1 of SKOV3/DDPⅡwere up-regulated 3.86,28.1 and 14.6 folds than those in SKOV3/GFP cells after eighth DDP treatment, separately. While PTEN of SKOV3/DDP Ⅱ was decreased 3.77 folds. Conclusions We have successfully established platinum-resistent EOC mice model,which provides a new platform for further study on chemoresistant reversal and individualized clinical treatment. The results shown that potential mechanisms of SKOV3/DDPⅡDDP-resistance included over-expressed BRCA1 gene may be promote DNA damage repair, elevate XIAP gene to decrease cell apoptosis,up-regulated STAT5 gene and decrease PTEN gene to stimulate proliferation.

OBJECTIVE:To investigate the effects of sevoflurane combined with remifentanil on intraoperative related indica-tors and quality of postoperative recovery in patients with general anesthesia. METHODS:52 patients with elective abdominal sur-gery were randomly divided into observation group and control group. All patients were treated with etomidate 0.3 mg/kg+atracuri-um 0.5 mg/kg+remifentanil 1μg/kg for anesthesia induction;then observation group was received sevoflurane by inhalation and con-trol group was propofol by infusion. The SBP,DBP,HR and BIS in 2 groups were recorded before anesthesia induction(T0),after anesthesia induction(T1),time of intubation(T2),skin incision(T3),10 minutes after establishing pneumoperitoneum(T4),end of pneumoperitoneum(T5) and extubation(T6),respectively. Operation and anesthesia duration,recovery time and extubation time, MMSE score and incidence of adverse reactions were recorded. RESULTS:SBP and HR in T6 and DBP in T4-6 in 2 groups were sig-nificantly higher than T0 of same group,BIS in T1-5 was significantly lower than T0,the differences were statistically significant(P<0.05),however,there was no significant difference between 2 groups (P>0.05). Recovery time and extubation time in observa-tion group were significantly lower than control group(P<0.05),there was no significant difference in the operation and anesthesia duration between 2 groups(P>0.05). MMSE scores in 2 groups were significantly lower than before after 0.5 h and 1 h of extuba-tion,and control group was lower than observation group(P<0.05 or P<0.01);MMSE scores in 2 groups were significantly high-er than 0.5 h and 1 h after extubation(P<0.05),however,there was no significant difference between 2 groups and before(P>0.05). There was no significant difference in the incidence of adverse reactions between 2 groups(P>0.05). CONCLUSIONS:Sevoflurane combined with remifentanil has satisfactory anesthesia,sevoflurane has better controllability,with good safety.

Objective To investigate the effects of overexpression of Mash-1 gene on functional recovery and neural differentiation of embryonic stem cells in spinal cord injury mice. Methods CE3 cell line with overexpression of Mash-1 gene was generated with murine stem cell virus. Spinal cord injury model was established with forceps compression in 4-week-old KM mice. Normal saline (model group, n=12), CE3 cells with or without overexpression Mash-1 gene (CE3-Mash-1 and CE3 groups, n=12 respectively) were transplanted into the ar-eas of injury 3 days after injury. They were assessed with the Basso Mouse Scale (BMS) 1, 7, 14, 21, and 28 days after injury. 6 mice from each group were sacrificed 14 and 28 days after injury respectively. The spinal cord area remained were observed with HE stained, and the expression of Oct3/4, nestin,β-tubulin III and glial fibrillary acidic protein (GFAP) were detected with immunofluorescence in the injured spinal cord in the CE3 and CE3-Mash-1 groups. Results The score of BMS significantly improved in CE3 and CE3-Mash-1 groups com-pared with that of the model group (F>84.471, P<0.05), with the more area of spinal cord remained (F>49.990, P<0.05). There were less Oct3/4 positive cells in the CE3-Mash-1 group than CE3 group (t=5.439, P<0.001), with more nestin (t=-7.536, P<0.001) andβ-tubulin III (t=-9.941, P<0.001) positive cells. However, there was no significant difference in GFAP positive cells between CE3-Mash-1 and CE3 groups (t=1.701, P>0.05). Conclusion Overexpression of Mash-1 gene promotes CE3 cells to differentiate into neurons in spinal cord injury mice, and improve the motor function recovery.
