To investigate the suitable site environment for Atractylodes lancea, field trials in different niches was carried out, and the seedling growth, biomass and volatile oil components in different microhabitas was studied. The study found that the survival rate, plant height, volatile oil content of those which growing under the bamboo were significantly higher than those exposed in the open field. The survival rate understory was (76 ± 15.1) %, plant height understory was (77 ± 14. 8) cm and the summation of the four kinds of volatile oil content understory reached up to 4.09%; The same evaluation values of these indicators of the four faces in the open field respectively: survival rate is 30%, plant height was (77 ± 14.8) cm and the summation of the four kinds of volatile oil content was 2.24%. But, the yield of the understory (41 ± 22.3) g was significantly lower than those four faces in the open field (104.5 g) on the contrary. For the four open field towards, the yield of the east facing, which organic matter and other nutritional conditions were better than others, was significantly higher than those in the other facings. A. lancea was found to be an anti-poor and shading-like or growing in east facing slope herb through the correlation analysis of light, temperature, soil and leaf nutrients with seedling growth, biomass and volatile oil components. It also reminds us that the understory herb with high survival rate, low incidence, low management costs, and high medicinal ingredients, although it's production is not so high, but it can be improved by increased organic fertilizer. So the ecological planting patterns which can intercropping herbs with the forest was proposed.

OBJECTIVEIn order to provide scientific basis for introduction breeding and production regionalization of Panax notoginseng, the environment of producing area, agronomic traits and medicinal material output were investigated.
METHODUsing field survey sampling at harvest time, agronomic traits indicators of leaf segment, stem segment and roots segment etc. of commodity P. notoginseng, longitude and latitude, elevation, soil type, landform of producing area were measured and observed.
RESULTThe P. notogiseng cultivation was expanding from traditional area like Wenshang to new areas as Honghe, Kunming, Qujing at large scale. Comparing with traditional cultivated fields, the elevation of new fields, which are red soil of moderate or low mountain slopes and gentle hills between 1 800-2 130 m, increases markedly. The agronomic traits of new cultivated fields such as plant height, stem diameter, the ground and underground biomass were better than those of traditional cultivated fields in varying degree. Furthermore, the root weight, taproot weight, taproot length and other agronomic index augmented more than 20%. Comparison among different cultivated fields showed P. notoginseng of Honghe Shiping Niujie, Kunming Shilin Guishan, Honghe Jiangshui Guanting etc. had better agronomic traits, the plant were thick and tall, the taproot and the top of reed were large, the number of root was more. Inversely, P. notoginseng of Kunming Guandu Xiaoshao, Guangxi Jingxi Lutong, Wenshang Yanshan Jiangna were thin and small. Cluster analysis showed that cultivated fields of P. notoginseng which was across clustered by traditional and new cultivated fields can be divided into three groups, including a high-yielding region insist of three new cultivated fields Honghe Shiping Niujie, Kunming Shilin Guishan, Honghe Jiangshui Guanting and one traditional cultivated field Wenshan Yanshan Jiangna. Correlation analysis indicated that the size and weight of taproot and top of reed were significantly positive correlated with plant height, stem diameter, leaf size, leaf weight and stem weight. Regression analysis pointed out that stem diameter, leaf width, leaf length/width, leaf weight were the main factors affecting the dry weight of taproot, and the main factors influencing the dry weight of top of reed were plant height, petiole, leaf length, leaf width and other agronomic traits.
CONCLUSIONFrom agronomic traits, P. notoginseng in new cultivated fields were more robust than that in traditional fields, but besides the length of taproot, the difference of rest agronomic traits didn't reach the significant level. It is suggested that, in the west and the north of traditional area, the red soil land of moderate or low mountain slopes and gentle hills where the elevation is between 1 800-2 130 m is suitable for cultivating P. notoginseng. Honghe Shiping Niujie, Honghe Jianshui Guanting, Kuming Shilin Gongshan can be used as vital development area for commodity P. notoginseng.

OBJECTIVETo investigate the diagnosis and differential diagnosis of granulocytic sarcoma (GS).
METHODSThe morphological and immunological characteristics of 12 cases of GS were studied. FAB classification was made by peripheral blood, bone marrow picture and bone marrow biopsy assay.
RESULTSAll of the 12 cases presented with lymphadenopathy and soft tissue mass. Histologically, the tissue infiltration of GS was composed of blastic cells with round to oval nuclei showing an even, pale chromatin pattern. Some with cleaved or notched nuclei. There were prominent nucleoli and scant cytoplasm in the cells and mitosis was easily found. Immunohistochemically, CD(45) and lysozyme were positive in all of the cases, MPO in 11 (92%), CD(68) in 10 (83%), CD(34) in 5 (42%), and TdT in 2 cases (17%). CD(15) and Mac387 were mainly expressed in mature granulocytes. Examination of bone marrow sections and marrow aspirate smears showed that out of the 11 cases tested 8 were AML-M(2), 2 AML-M(1) and 1 AML-M(0). Only 1 case was nonleukemic, ie. solitary granulocytic sarcoma.
CONCLUSIONGranulocytic sarcomas are difficult to identify in routine paraffin-embedded tissue sections and usually misdiagnosed as non-Hodgkin's lymphomas. Immunohistochemistry study with a panel of antibodies in combination with bone marrow and peripheral blood examination are helpful in identification of granulocytic sarcoma.

OBJECTIVETo investigate effects of two kinds of anti-cancer bioactive peptide (ACBP) on proliferation and cell cycle in human nasopharyngeal carcinoma strain CNE.
METHODSCell culture was used in vitro, CNE cells were exposed to different concentration ACBP, in all groups, contrast groups were set up. And 24, 48, 72 hours later, growth characteristics of CNE cells were studied by morphological observation and MTT assay . Cell cycle and apoptosis were analyzed by flow cytometry (FCM).
RESULTSIn normal contrast group, CNE cells grew intensively and contacted with each other. However, cells which were treated with ACBP were inhibitory greatly in higher dose ACBP group, necrosis could be found. MTT assay showed that ACBP inhibited growth of CNE cell. FCM showed that ACBP (20.0 microg/ml) could raise cell ratio of S phase and induce apoptosis of CNE cells. CNE cells were treated by two kind of ACBP (5.0 microg/ml) for 24 h, FCM showed that early apoptosis rate were (11.8 +/- 0.3)% and (8.1 +/- 0.2)% respectively, which showed statistical significance in comparison with control group (t = 42.535, 47.300 respectively, P = 0.000). Under light microscope, some sings of cell apoptosis including coagulation of chromatin, fragmentation of nuclei and apoptotic body could be found.
CONCLUSIONSTwo kinds of ACBP inhibited human nasopharyngeal carcinoma strain CNE proliferation and arrested the cells to S phase, also induced the cells to apoptosis. Nasopharyngeal neoplasms;

OBJECTIVEGas-containing encephalo-meningitis is very rare. There have only been a few cases reported in the literature. The majority of neonatal cases reported in literature died. We report a case of a 5-day-old neonate who developed diffuse pneumocephalus from Enterobacter cloacae septicemia and intracranial infection.
METHODThis neonate was initially treated with penicillin and mezlocillin. He also received phototherapy, intravenous infusion, correction of acidosis and other supportive therapy. Complete blood count, C-Reactive protein, cranial CT scan, blood culture, cerebrospinal fluid culture and biochemistry were tested repeatedly.
RESULTSThis neonate's condition deteriorated after admission. He developed respiratory distress, increased muscle tone and decreased level of consciousness. His WBC and C-reactive protein were elevated, while blood gas, electrolytes, liver enzymes and renal function were within normal range initially. Cranial CT scan was done which demonstrated diffuse pneumocephalus. He was transferred to a higher level hospital for further management at the request of the family. Blood culture done in our hospital subsequently showed growth of Enterobacter cloacae. The infant developed seizures and further deterioration in level of consciousness after transfer. Antibiotics were switched to penicillin and ceftizoxime. Cranial CT scan repeated 2 days after transfer showed hydrocephalus and some resolution of pneumocephalus. Cerebrospinal fluid (CSF) was aspirated from the lateral ventricles two weeks after admission. CSF culture also showed growth of Enterobacter cloacae. Antibiotic was switched to imipenem according to antibiotic sensitivity. His general condition was improved. Blood and CSF cultures were negative 1 month after admission. His head circumference at discharge was 34.6 cm. Repeat cranial CT scan at 4 month of age demonstrated severe hydrocephalus, diffuse leukomalacia and calcification. This infant suffered significant neurodevelopmental deficit. Muscle tone was diffusely increased. Head circumference at 9 month of age was 48.4 cm.
CONCLUSIONThis case suggests the importance of Enterobacter cloacae infection in the newborns. Our analysis of 34 cases of Enterobacter cloacae infection showed that 93.75% - 100% were sensitive to quinolones, 94.12% were sensitive to imipenem, 73.33% were sensitive to gentamicin, 50% were sensitive to piperacillin-tazobactam. Enterobacter cloacae is generally not sensitive to penicillin, first and second generation cephalosporins (0 - 21.4%). Enterobacter cloacae septicemia and intracranial infection in neonates have a high mortality rate and can result in severe neurodevelopmental deficit in survivors.

The output and agronomic characters of 3-year-old Panax notoginseng cultured under stereo structure (upper, middle and down layers) were investigated, and the annual change of N, P and K of its planting soil were also studied. Results showed that, compared with field cultured Panax notoginseng, growth vigour and output of stereo-cultivation were significantly lower. But the total production of the 3 layers was 1.6 times of field. The growth vigor and production of P. notoginseng was in the order of upper layer > middle layer > down layer. The content of ginsenoside in rhizome, root tuber and hair root of P. notoginseng was in the order of upper layer > field > middle layer > down layer. Organic matter content and pH of stereo-cultivation soil decreased with the prolonging of planting time, which with the same trend of yield. Organic matter content of stereo-cultivation soil was significantly higher than field, but the pH was significantly lower. Contents of total and available N, P and K in stereo-cultivation soil and field decreased with the prolonging of planting time. The content of N and P were in the order of upper layer > middle layer > yield > down layer, the content of K was in the order of upper layer > middle layer > down layer > yield. Compared with field, the proportion of N and P in the organ of underground (rhizome, root tuber and hair root) of upper layer were increased, while decreased in middle and down layers. Proportion of K in underground decreased significantly of the 3 layers. In conclusion, the agronomic characters and production of stereo-cultivation were significantly lower than that of yield. But the total production of the 3 layers were significantly higher than field of unit area. And the aim of improving land utilization efficiency was achieved. Nutritions in the soil of stereo-cultivation were enough to support the development of P. notoginseng, which was not the cause of weak growth and low production. The absorbing ability of P. notoginseng to N, P and K nutrients was decreased by stereo-cultivation mode. So, improve the growth vigour of P. notoginseng from the perspective of adjusting the stereo-cultivation mode so as to improve the nutrient absorption capacity is the future direction.
