Objective:To evaluate the six-degree setup errors of tumors of cervical vertebra, thoracic vertebra and lumbar vertebra by image guided radiotherapy. Methods:From May 2013 to June 2014, 30 patients with spinal malignant tumors(10 patients of cervical vertebra, thoracic vertebra and lumbar verte-bra respectively) were treated with Elekata Synergy accelerator(Elekta company,Sweden). Six-degree set up errors were corrected using HexaPODTM evoRT bed under image of on board cone beam computed tomography ( CBCT) guided. All the patients received kilovoltage CBCT before receiving radiotherapy and after correction. The acquired images were co-registered with planning CT with bone window. The data of 838 CT images were analyzed and the errors of translational directions X ( lateral ) , Y ( lngitudi-nal),Z(vertical)and rotational directions RX(pitch), RY(roll), RZ(yaw) were recorded. The data were compared by t-test using SPSS 13. 0. Results:The absolute translational setup errors in X, Y and Z axes of cervical vertebra before correction were (1. 71 ± 0. 10) mm, (1. 81 ± 0. 11) mm and (1. 94 ± 0. 09) mm respectively:(3. 17 ± 0. 19) mm, (4. 26 ± 0. 28) mm and (2. 18 ± 0. 12) mm for thoracic vertebra, and (2. 69 ± 0. 24) mm, (3. 33 ± 0. 26) mm and (2. 86 ± 0. 21) mm for lumbar vertebra. The residual setup errors in X, Y and Z axes of cervical vertebra were (0. 5 ± 2. 4) mm,(0. 01 ± 2. 4) mm and (2. 4 ± 1. 4) mm, respectively after correction;(1. 17 ± 0. 11) mm,(0. 26 ± 0. 30) mm and (0. 08 ± 0. 12) mm for thoracic vertebra and (1. 09 ± 0. 24) mm,(2. 03 ± 1. 26) mm and (0. 06 ± 0. 51) mm for lumbar vertebra. The t-test of paired data of set up errors before and after CBCT showed significant difference in three translational directions of cervical vertebra and thoracic vertebra, only Z (t= -3. 518,P<0. 001) for lumbar vertebra. The absolute rotational setup errors in RX,RY and RZ axes of cervical vertebra before correction were 0 . 67 ° ± 0 . 04 ° ,1 . 06 ° ± 0 . 06 ° and 0 . 78 ° ± 0 . 05 ° respec-tively. 0. 62° ± 0. 05°, 0. 75° ± 0. 06°, and 0. 84° ± 0. 06° for thoracic vertebra, 0. 59° ± 0. 06°, 0. 80° ± 0. 07°, and 0. 73° ± 0. 06°for lumbar vertebra. The rotational directions RX, RY and RZ axes of cervical vertebra were 0 . 27 ° ± 0 . 14 ° , 1 . 20 ° ± 0 . 04 ° and 0 . 28 ° ± 0 . 05 ° respectively;0 . 02 ° ± 0 . 20 ° , 0. 05° ± 0. 26°and 0. 64° ± 0. 16°for thoracic vertebra and 0. 09° ± 0. 26°, 0. 50° ± 0. 05°,and 0. 03° ± 0. 16°for lumbar vertebra. The t-test of paired data of set up errors before and after CBCT showed signifi-cant difference in three rotational directions of cervical vertebra and lumbar vertebra, only RY(t=7. 106, P<0. 001)for thoracic vertebra. All the patients acquired pain relief and there was no radiation-induced toxicity detected clinically during a median follow-up of 6 months. Conclusion:Six-degree set up errors of spine tumors were corrected effectively with HexaPODTM evoRT bed under CBCT image guided and its feasibility in day-to-day clinical practice has been demonstrated.

In this study, an approach based on triple-color fluorescence probes was developed for screening potential nephro-protective bioactive substances. Three fluorescent probes (i. e. FDA, MTR and Hoechst 33342) were used to label HK-2 cells injured by doxorubicin hydrochloride, and cellular fluorescence images were subsequently acquired and analyzed by a cellular-fluorescence image microscopy platform. The established method was applied to screening 53 components of Carthami Flos, and three components C17, C18 and C19 were found to exhibit nephroprotective effects against doxorubicin hydrochloride induced injury on HK-2 cells. Eight compounds (i. e. hydroxysafflor yellow A, 6-hydroxykaempferol-3-O-rutinoside-6-O-glucoside, 6-hydroxykaempferol-3,6-di-O-gluco-side or 6-hydroxykaempferol-6, 7-di-O-glucoside, 6-hydroxykaempferol-3-O-rutinoside, 6-hydroxykaempferol-3-O-glucoside or 6-hydroxykaempferol-7-O-glucoside, rutin, isoquercetin, and kaempferol-3-O-rutinoside) in components C17, C18 and C19 were preliminarily identified by liquid chromatography-mass spectrometry (LC-MS). Isoquercetin, rutin, kaempferol-3-O-rutinoside, and hydroxysafflor yellow A were confirmed by comparing with reference substances, Further study indicated that these four compounds had moderate nephroprotective effects, while isoquercetin showed a significant nephroprotective effect in a dose-dependent manner. These results suggest that isoquercetin, rutin, kaempferol-3-O-rutinoside and hydroxysafflor yellow A might be the nephroprotective bioactive substances in Carthami Flos.

A bacterium(designated as LW-3), capable of degrading Chlorimuron-ethyl, was isolated from the long-term contaminated soil by Chlorimuron-ethyl. Based on physiological and biochemical analyses and sequences comparison of 16S rDNA, strain LW-3 was identified as Pseudomonas sp. LW-3 could use Chlorimuron-ethyl as sole nitrogen source for growth. The optimum pH and temperature for degradation of Chlorimuron-ethyl were pH 6.5~7.2 and 30?C~35?C, at same temperature the pH change to the Chlorimuron -ethyl degrading influence is large. When the pH and temperature were pH 6.5 and 32?C, 50 mg/L Chlori- muron-ethyl could be degraded to 70%~80% level within 7 days.

ObjectiveTo investigate the economic status of psychiatric patients and their families in Shaoxing area in Zhejiang Province.MethodsA self-edited questionnaire was used to survey the annual income and expenses for medical treatment among psychiatric patients and their families.ResultsThe average annual income of per person in psychiatric family was (3823.07±3354.99) Yuan while average annual income of per psychiatric patient was (1918.20±5188.42) Yuan, which were only 62.3% and 31.2% of the rural controllable annual income, 20.9% and 14.2% of urban controllable annual income in Shaoxing area. In the meantime, 30.43% psychiatric patients did not have any incomes and 47.43% were below 500 Yuan per year. Engel coefficient was (59.65±24.36). The average expense for medical treatment was 1052.54 Yuan per year, which was 54.9% of annual income of the psychiatric patients. In some illness, this rate was as high as 90% or above.ConclusionThe incomes of psychiatric family members and psychiatric patients themselves are much lower than the local average level, while they would be spent more than a half of the income on their medical treatment. Psychiatric patients as well as their family members are the extremely low income and weak social class and need help by the government and society.

Objective To establish HPLC analysis methods and fingerprint of different proportions of Angelicae Pubescentis Radix in Angelicae Sinensis Radix; To use HPLC fingerprint method to identify the adulteration of Angelicae Pubescentis Radix in Angelicae Sinensis Radix. Methods Agilent TC-C18 column (5 μm, 4.6 mm × 250 mm) was adopted. Acetonitrile (A) - 0.05% phosphoric acid (B) was the mobile phase, and the gradient elution (0–20 min, 95%–75%B; 20–60 min, 75%–65%B; 60–80 min, 65%–5%B) was used; The flowrate was 1 mL/min; Detection wavelength was 254 nm; Column temperature was 30 ℃. The HPLC spectra of Angelicae Sinensis Radix, Angelicae Pubescentis Radix and adulterated samples were compared and analyzed by using TCM chromatogram fingerprint similarity evaluation system. Results Angelicae Sinensis Radix and Angelicae Pubescentis Radix showed good chromatographic peaks in chromatogram separation. 11 peaks in HPLC fingerprint could be used as the mark, including 7th peak for ferulic acid, 32th peak for osthole, and 34th peak for columbianadin. Conclusion This method is rapid, simple and feasible, can fully reflect the quality of Angelicae Sinensis Radix and clearly identify whether Angelicae Pubescentis Radix is adulterated in Angelicae Sinensis Radix.

This study was aimed to investigate the clinico-pathological features, diagnosis and treatment of the 8p11 (eight p11) myeloproliferative syndrome (EMS). Morphological changes of cells were evaluated by bone marrow smear and biopsy. The cell immunophenotypes were analysed by flow cytometry. Karyotypes were determined by conventional cytogenetic method, and bcr/abl fusion gene was detected by reverse transcription-polymerase chain reaction (RT-PCR). The results indicated that EMS was a relatively rare disease characterized by the occurrence of a bcr/abl-negative myeloproliferative disorder and a T-cell lymphoblastic lymphoma (T-LBL). Bone marrow examination showed myeloid hyperplasia or myeloproliferative neoplasm, often accompanied by eosinophilia. Flow cytometric immunophenotyping showed increased myelomonoblasts; cytogenetic analysis showed a translocation at the 8p11 locus; RT-PCR demonstrated non bcr/abl fusion gene. At the molecular level, all cases carried a chromosomal abnormality involving the fibroblast growth factor receptor 1 (FGFR1) at chromosome 8p11. Up to now, 11 partner genes have been identified and associated with FGFR1 rearrangements. The most common partner is ZNF198 on chromosome 13q11-12. Majority of patients terminate in acute myeloid leukemia which is resistant to conventional chemotherapy. Currently, the only curative option appears to be allogeneic hematopoietic stem cell transplantation. In conclusion, EMS is myeloid and lymphoid neoplasm, associates with FGFR1 rearrangements. It is usually misdiagnosed as T-LBL, atypical chronic myeloid leukemia (aCML) or chronic myelogenous-monocytic leukemia (CMML). Timely cytogenetic and molecular biological examination is vital in order to avoid misdiagnosis and mistreatment.

OBJECTIVETo observe the therapeutic effect of He's Santong needling method on neurological functional deficit in the patient of ischemic apoplexy, and search for an effective method for treatment of ischemic apoplexy.

METHODSAccording to the randomized and multi-central trial principle, 319 cases enrolled were randomly assigned to an observation group of 161 cases and a control group of 158 cases. The observation group were treated with He's Santong needling method, i. e. blood letting, puncturing with a red-hot needle and filiform needle therapy by stages, and the control group were treated with acupuncture at 12 points of the hand and foot routinely selected in the department, once daily. After treatment of 30 days, changes of neurological functional deficit score were investigated in the two groups.

RESULTSThe total effective rate was 91.93% in the observation group and 70. 25% in the control group with a significant difference between the two groups (P<0.05); there was no significant difference in changes of the neurological functional deficit score between the patients at the acute stage and the convalescence (P > 0.05).

CONCLUSIONThe therapeutic effect of He's Santong needling method on ischemic apoplexy at acute stage or convalescence is better than that of the routine point selection.
