Purpose To evaluate the correlation among diffusion weighted imaging (DWI), tumor Cellularity and hypoxia-inducible factor-1α (HIF-1α) for the high and low grade astrocytoma. Materials and Methods DWI was applied with 33 patients with astrocytoma confirmed by pathology, and ADC value was measured. Tumor Cellularity was measured using Scion Image 4.0.3.2. The expression of HIF-1α was tested using immunohistochemisty. Results Mean ADC value was higher in the low grade astrocytoma than that in the high grade astrocytoma (t=7.300, P<0.001). The tumor Cellularity was higher in the high grade astrocytoma than that in the low grade astrocytoma (t=-3.845, P<0.01). HIF-1αexpression could be demonstrated in the low grade [(20.08±10.01)%] and high grade [(47.91±19.03)%] astrocytoma. The negative correlation was demonstrated between ADC value and HIF-1αand tumor Cellularity (r=-0.756,-0.617;P<0.001). The positive correlation was demonstrated between HIF-1αand tumor Cellularity (r=0.622, P<0.001). Conclusion ADC value can be used to discriminate the low and high grade astrocytoma, and the role of HIF-1αshould be further to study with enlarged sample.

Objective To evaluate the pattern of energy metabolism and nutrients intake in patients with chronic viral hepatitis and posthepatitic cirrhosis to effectively direct their nutrition therapy.Methods Resting energy expenditure (REE) was measured with open-circuit indirect Jorimetry in 60 patients with chronic viral hepatitis and 60 patients with posthepatitic cirrhosis.Their normal basal energy expenditure (BEE) was predicted by Harris-Benedict equation and energy intake (EI) was determined by diet recall. Correlation between REE and indicators for nutrition assessment was analyzed.Results REE was (77? 21) kJ?kg~(-1)?d~(-1) in 60 patients with pusthepatitic cirrhosis,significantly lower than BEE[(95?16) kJ? kg~(-1)?d~(-1)(P0.05,and their EI was (127?34) kJ?kg~(-1)?d~(-1),1.41?0.43 times as REE,in which PROI was (1.02?0.29) g?kg~(-1)?d~(-1),1.31?0.61 times as PROE (0.87?0.34) g?kg~(-1)?d~(-1),also indicating a negative nitrogen balance (-2.02?4.07).REE,EI and intake of three nutrients,serum level of albumin and prealbumin (PA) and body weight significantly decreased in patients with posthepatitic cirrhosis,as compared to those in patients with chronic viral hepatitis (P

A patient was admitted for menopause for 2 years and abnormal vaginal bleeding and abdominal pain for 2 months. Gynecological examination revealed uterine atrophy without abnormal findings in the bilateral adnexa. CA125 and CEA levels were normal. The patient underwent laparoscopically assisted vaginal hysterectomy with bilateral salpingo-oophorectomy. Pathological examination of the surgical specimens revealed synchronous primary cancers stage Ia in both the endometrium and the right fallopian tube. The patient then received 6 cycles of chemotherapy with oxaliplatin combined with docetaxel given intravenously and remained alive without evidence of recurrence. Synchronous primary endometrial and fallopian tube cancer is a rare clinical entity, and laparoscopic surgery with postoperative chemotherapy can be considered for stage I patients.

OBJECTIVETo evaluate the efficacy and safety of three different spinal rotation manipulations for the treatment of lumbar disc herniation.

METHODSFrom September 2011 to April 2013,180 patients diagnosed as lumbar disc herniation were randomly divided into seat fixed rotation group (A), lateral position rotation group (B) and supine position rotation group (C) by using a digital table. Finally 10 patients were excluded and dropped, 170 patients were included in the study. There were 57 patients in group A, 57 patients in group B and 56 patients in group C. Baseline demographic characteristics of patients, clinical findings and indexes of health status had no statistically differences among three groups (P > 0.05). The manipulation was performed every other day, and the treatment duration for all patients was 3 weeks. Body pain (BP), Physical function (PF) in SF-36, Oswestry Disability Index (ODI) and adverse reactions were observed statistically 6 weeks, 3 months, 6 months, one year and two years after finishing treatment.

RESULTSBP, PF scores in 3 groups were significantly improved and ODI scores were significantly lower than those before treatment and the differences were statistically significant (P < 0.05); However, there was no significant difference among three groups in the BP, PF and ODI scores (P > 0.05). There were no obvious and serious adverse reactions among these groups.

CONCLUSIONBased on the theory of dislocation of bone joints in TCM, three kinds of spinal rotation manipulations can be used safely for the treatment of lumbar disc herniation, and the efficacy was similar.

Objective: To observe the effects of moxibustion pretreatment on the protein expressions of epidermal growth factor receptor (EGFR), phosphorylation extracellular signal-regulated kinase 1/2 (p-ERK1/2) and activated protein-1 (AP-1), the key factors of extracellular signal-regulated kinase signaling transduction pathway in gastric tissue of rats with stress-induced gastric mucosal damage, and to discuss the mechanisms of moxibustion therapy in promoting the restoration of damaged gastric mucosa.
Methods: Thirty Sprague-Dawley (SD) rats were randomly divided into a normal group, a model group, and a moxibustion group using the random digits table, 10 in each group. Except the rats in the normal group, rats in the other two groups were used to make stress-induced gastric mucosal damage model using restraint and cold stress. Before modeling, rats in the moxibustion group were alternately treated with moxibustion at Zusanli (ST 36) and Zhongwan (CV 12), or Pishu (BL 20) and Weishu (BL 21), once a day, for a total of 8 d. Histological changes of gastric mucosa were observed under the light microscopy, the expression of gastric tissue p-ERK1/2 was detected by immunohistochemistry assay, and the protein levels of EGFR and AP-1 were measured by Western blots.
Results: Compared with rats in the normal group, gastric mucosal damage was more serious, and protein expressions of gastric tissue EGFR, p-ERK1/2 and AP-1 increased in the model group (P<0.01,P<0.05,P<0.05). Compared with rats in the model group, gastric mucosal damage was milder, and protein expressions of gastric tissue EGFR, p-ERK1/2 and AP-1 increased in the moxibustion group (allP<0.01).
Conclusion:Moxibustion at Zusanli (ST 36), Zhongwan (CV 12), Pishu (BL 20) and Weishu (BL 21) couldincrease EGFR, p-ERK1/2 and AP-1 expression levels in gastric tissue of stress-induced gastric mucosal damage rats, maintain the information transfer function of ERK signaling transduction pathway, and promote restoration of gastric mucosal damage.

The aim of this research is to refine the protocol of purification of SA and identify the character of SA. By utilizing the cold-denaturing method, most of other kinds of protein were screened out and SA was purified from the fermentation broth of L-183 by using the refined affinity chromatography method. The rate of recollection was checked to be 75%～85%. By identification, it is indicated that the molecular weight of self-made SA was 74.5kD, the biotin-combining number 3.2, the activity 11.2u/mg, the pI around 7.4. So, the essential characters of SA are same as described by documents.

OBJECTIVETo investigate the role of small interfering RNA (siRNA) targeted to survivin in combination with 5-fluorouracil (5-FU) in inhibiting the proliferation of MCF-7 cells.

METHODSA siRNA targeted to survivin was synthesized and transfected into MCF-7 cells via lipofectin. Changes of the cell growth activity in response to combined treatment with survivin siRNA and 5-FU or 5-FU treatment alone was evaluated by MTT assay. The Q method of Jin Zhenjun was used to evaluated synergism between the synthesized siRNA and 5-FU.

RESULTSTreatment with 5 nmol/L siRNA reduced the IC50 of 5-FU from 4.42 to 1.18 microg/ml, and the inhibitory effect of combined treatment on MCF-7 cells was higher than that of 5-FU alone (F=26.74, P<0.01). Synergism effect was observed between 5-FU at lower concentrations and survivin siRNA.

CONCLUSIONsiRNA may enhance the effectiveness of 5-FU in inhibiting the proliferation of MCF-7 cells.

OBJECTIVETo study the anti-glioma effect of recombinant adenovirus mediated combined gene therapy of bFGF-siRNA and HIV1-Vpr in vivo.

METHODSMouse glioma model was established by injecting 5 × 10(6) LN229 cells into BALB/c-nu nude mice. 30 nude mice were randomly divided into 5 groups: the negative control group, mock group, bFGF-siRNA group, Vpr group and combined therapy group, which at regular intervals were injected with PBS, rAd5-null, rAd5-bFGF-siRNA, rAd5-Vpr, rAd5-bFGF-siRNA plus rAd5-Vpr, respectively. The tumor volume was recorded every third day to draw a growth curve. After four weeks treatment, the mice were killed and specimens were taken. HE, immunohistochemical and TUNEL staining were performed to observe the cell morphology, detect the changes of relevant target proteins and cell apoptosis, respectively. Also the ultrastructural changes were observed by electron microscopy.

RESULTSThe tumor growth inhibition rates were 36.9%, 37.2% and 58.6% in the bFGF-siRNA group, Vpr group and combined therapy group, respectively, and the combined therapy group showed the most significant effect (P < 0.05). Also the results of HE, immunohistochemical and TUNEL staining revealed that the combined therapy group had the best effects on proliferation inhibition and apoptosis induced in glioma cells (P < 0.05). The most significant ultrastructural changes were observed in the combined therapy group.

CONCLUSIONThe combined gene therapy of bFGF-siRNA with Vpr shows a prominent and synergistic anti-glioma effect compared with that of mono-gene therapy in nude mice.
