In order to make sure whether Panax notoginseng is sensitive to chloridion and guide fertilization in planting of P. notoginseng, the effects of the different proportion of potassium chloride (KCl) and potassium sulfate (K2SO4) on the yield, quality of P. notoginseng were studied. The results showed that K fertilizer significantly improved the growth of P. notoginseng and increased the biomass per plant or per pot and the content of N, P, K and the content of saponin. In cases of conditions such as potassium, and the effects of K2SO4 on increasing the petiole length, leaf size, rhizome length, root length, and content and accumulation of Ginsenoside Rg1 were better than those of KCl. While compared with K2SO4, KCl was more conducive to augmenting height, root width, the biomass of shoot, rhizome, root and the content of Ginsenoside Rb1 and Rd. There was not remarkable difference in agronomic characters, biomass and the content of N, P, K among KCl, K2SO4 and the combination of KCl and K2SO4. However, the content of saponin of the treatment with combination of KCl and K2SO4 was significant higher than that of single KCl or K2SO4 treatments. K fertilizer significantly increased yield and the content of saponins. And P. notoginseng was not sensitive to chloridion. KCl increased the yield and the content of saponins of P. notoginseng as well as K2SO4, and the combination treatment was superior to single treatment. It is recommended that the KCl should be adopted in production, to reduce the cost of potash fertilizer.

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 detect the mRNA and protein expression of interferon-inducible transmembrane protein-1 (IFITM1) in Peutz-Jeghers syndrome (PJS) and investigate the role of IFITM1 in the occurrence, development and carcinogenesis of PJS polyps.

METHODSReverse transcription-PCR was employed to detect the mRNA expression of IFITM1 in 16 PJS polyp samples, adenomatous polyp tissues, colon adenocarcinoma samples, and normal intestinal mucosal tissues. The protein expression and localization of IFITM1 in these tissues (32 cases for each) were detected with immunohistochemical (IHC) staining.

RESULTSThe IFITM1 mRNA expression was detected in all these tissues, and the expression intensity increased in the order of normal intestinal mucosa, PJS polyp, adenomatous polyp, and colon adenocarcinoma (F=92.704, P=0.000). IHC revealed that IFITM1 protein was localized mainly on the cell membrane and in the cytoplasm, with increased expression intensity in the same order as its mRNA and showing significant differences between the tissues by several rank-sum test (Kruskal-Wallis H, chi(2)=37.036, p=0.000).

CONCLUSIONThe expression level of IFITM1 is associated with the progression of the carcinogenetic process in PJS polyp, and can be used as a sensitive biomarker for diagnosis and prognostic evaluation of PJS.

OBJECTIVETo survey the incidence of acute febrile reaction in elderly patients receiving intravenous zoledronic acid for osteoporosis and identify the related factors.

METHODSThirty-eight elderly patients with osteoporosis were hospitalized and treated with intravenous infusion of 5 mg zoledronic acid in 2010. The incidence of acute fever reaction was observed in these patients , and the time of fever onset, duration, average maximum temperature, and antipyretic drug used were recorded. The patients with and without acute febrile reaction were compared for age, duration of osteoporosis, sex ratio, use of parathyroid hormone before zoledronic acid treatment, β-fragment of collagen breakdown, calcitonin, osteocalcin, serum calcium, and use of anti-osteoporosis drugs before the treatment.

RESULTSAcute fever reaction occurred in 12 (31.6%) of the patients. Two of the patients had fever on the day of zoledronic acid treatment, and the other patients developed fever after the first day of treatment, with a mean duration of 1 day and a maximum temperature of (38.5∓0.84) degrees celsius;. The fever was treated with a mean of 3.55∓1.21 pseudoephedrine tablets. The patients with fever showed significantly higher parathyroid hormone levels before treatment than those without fever (P<0.05); osteocalcin, calcitonin, β-fragment of collagen breakdown, or serum calcium showed no significant difference between the two groups.

CONCLUSIONAcute febrile reaction, often moderate and transient, is common in elderly patients receiving intravenous zoledronic acid for osteoporosis, and its occurrence is possibly associated with parathyroid hormone levels before the treatment.

OBJECTIVETo compare the therapeutic effects of acupuncture combined with drug and simple drug for treatment of male osteoporosis.

METHODSFifty-five cases were divided into an observation group (25 cases) and a control group (30 cases) randomly. The observation group was treated with acupuncture and moxibustion at Pishu (BL 20), Shenshu (BL 23), Mingmen (GV 4), Shenque (CV 8) and so on combined with taking Alendronate, while the control group was treated with taking Alendronate simply. The improvement of both Integral of Clinical Symptoms (ICS) and Bone Mineral Density (BMD) of two groups was observed after 6 months treatment.

RESULTSThe ICS of two groups after treatment both decreased significantly (both P < 0.001), and the decreasing degree in observation group was more significant than that in control group (P < 0.001). The BMD of lumbar vertebrae and femur in observation group increased obviously than that before treatment (P < 0.01, P < 0.05). The increasing degree of BMD of lumbar vertebrae in observation group after treatment was more obvious than that in control group (P < 0.05). There were abdominal pain, diarrhea, nausea, vomiting, dyspepsia and other adverse reaction in control group, while the degree and occurrence rate of those in observation group alleviated and decreased obviously.

CONCLUSIONThe effect of acupuncture combined with drug for treatment of male osteoporosis is good with little adverse reaction. This method is better than taking Alendronate.

The aim of study was to establish the packaging system of the recombinant lentiviral vector encoding Gfi1 gene for eukaryotic expression and to realize the efficient, stable expression of Gfi1 32D cells so as to provide effective platform for further studying the development of Gfi1 gene in hematologic malignancies. The three-plasmid recombinant lentiviral vector consisting of transfer plasmid (pLOX-Gfi1/pLOX), the packaging plasmid (pCMVDeltaR8.2) and the envelop plasmid (pMD.G) was prepared and purified. Human embryonic kidney 293T cells were cotransfected with the three plasmids by lipofectamine 2000. After transfection for 48 hours, the viral supernatant was collected and the target cell 32D was transfected with the recombinant lentivirus; the Gfi1 integration and expression in 293T and 32D cells were detected by Western-blot. The results showed that the three plasmids of lentivirus could be transfected into 293T with high efficiency and packaged successfully, and the Gfi1 protein could be detected by fluorescent microscopy. The recombinant lentiviruses carrying Gfi1 could transfer and deliver Gfi1 gene to 32D cells, and the Gfi1 expression in 293T and 32D cell could be detected by Western blot. It is concluded that the recombinant lentivirus carrying Gfi1 can deliver target gene to 32D cells with high efficiency, and the expression of Gfi1 protein is stable in 32D.

OBJECTIVETo investigate the expression, localization and interrelationship of P27(kip1) and cyclin D3 in non-Hodgkin's lymphoma (NHL).

METHODSThe expressions of P27(kip1), cyclin D3 and index Ki-67 was detected in 100 NHL and 20 reactive lymph nodes by immunohistochemical technique. The expression and localization of P27(kip1) and cyclin D3 in 3 NHL cell lines were detected by Western blot, double immunolabelling and laser scanning confocal microscopy, respectively.

RESULTSIn general the expression of P27(kip1) in NHL was lower than in control group, and was negatively related to the tumor aggressiveness and proliferating activity; the expression of cyclin D3 in NHL was higher than in control group, and was positively related to the tumor aggressiveness and proliferating activity. There was a negative correlation between P27(kip1) and cyclin D3. Nevertheless, anomalous high P27(kip1) expression was found in a few NHL tissues with high expression of cyclin D3 and Ki-67. Overexpression and colocalization of P27(kip1) and cyclin D3 was found in Raji cell line.

CONCLUSIONSUnder expression of P27(kip1) and overexpression of cyclin D3 may play a role in the occurrence and development of NHL. Anomalous high P27(kip1) expression and its interaction with cyclin D3 may be another mechanism for tumor genesis of NHL.
