"Mistreatment by warming therapy" refers to various symptoms/syndromes caused by improper use of fire methods mentioned in Treatise on Febrile Diseases, which are similar to damaged yin induced fire-heat syndrome (injury of yin, consumption of qi, loss of yin, consumption of body fluid) manifested after radiotherapy and/or chemotherapy in modern clinics. Better efficacy was obtained in treating various symptoms/syndromes by using nourishing yin purging fire method. In this paper authors focuses on exploring guiding significance of using "Mistreatment by warming therapy" in treating non-small cell lung cancer (NSCLC).

OBJECTIVETo explore method of recombinant gene lentivirus containing LIM mineralization protein-1 (LMP-1) in transfecting bone marrow mesenchymal stem cells (BMSC), and to observe the effect of gene LMP-1 on proliferation effect and expression of BMSC.
METHODSSix clean SD rats aged 4 weeks were selected, bone marrow mesenchymal stem cells were extracted under sterile conditions and cultured to the third generation, then divided into three groups:control group (the third generation of BMSC), lentiviral vector transfection group (PGC-FU-GFP and Polybrene were injected into the third generation of BMSC) and recombinant gene transfection group (PGC-FU-LMP-1-GFP and Polybrene transfection were injected into the third generation of BMSC). After 48 hours' transfection, fluorescent expression were detected under immuno-fluorescence microscopy; lentiviral transfection efficiency were detected by flow cytometry; effect of lentiviral transfection on BMSC were evaluated by MTT; gene expression of transfected cells were determined by Western Blot.
RESULTS1) The third generation of BMSC was cultured successfully,and transfected with MOI:100. After 48 hours, green fluorescent expression were detected and transfection efficiency was 67% under immuno-fluorescence microscopy; 2) Compared to control group, there were no statistical differences between control group and other two groups; 3) Western blot teast showed that 72KDa specific band was observed in recombinant gene transfection group and its size was similar to LMP-1 fusion protein (50 kDa+28 kDa=78 kDa).
CONCLUSIONThere is no effect of recombinant gene lentivirus containing LIM on BMSC, and can effectively influence the expression of LMP-1.

The mechanism of long-term potentiation (LTP) in basolateral amygdala (BLA) was explored using field potential recording in rat brain slice preparation. Field potentials (field excitatory post-synaptic potentials, fEPSPs) in BLA were evoked with sharpened steel bipolar stimulating electrodes placed in the external capsule (EC). Two theta burst stimulations (TBS, interval=10 min) induced LTP in BLA. TBS-induced synaptic potentiation lasted for more than 30 min after the second TBS. LTP in BLA was input-specific and was blocked by N-methyl-D-aspartate receptor (NMDAR) antagonist 2-amino-5-phosphonovaleric acid (APV). The effect of protein kinase C (PKC) on LTP was then determined using PKC inhibitor chelerythrine chloride. Bath application of chelerythringe chloride had no effect on basic field potentials and paired-pulse ratio (PPR). However, in the presence of chelerythrine chloride, two TBS failed to induce LTP. In contrast, bath application of chelerythrine chloride 10 min after the second TBS did not affect the maintenance of LTP in BLA. These results indicate that LTP is NMDAR-dependent and PKC is involved in the induction and early maintenance of LTP in BLA.

OBJECTIVETo study expression of mutant p53 protein in workers occupationally exposed to benzidine and bladder cancer patients.
METHODSMutant p53 protein in serum from the workers occupationally exposed to benzidine and bladder cancer patients were determined with Immuno-PCR, while exfoliated urothelial cells in the urine samples were classified with Papanicolau grading.
RESULTSPositive rate of mutant p53 protein increased with the exposed intensity index in workers occupationally exposed to benzidine. The positive rate of mutant p53 protein in bladder cancer patients (83.3%) was significantly higher than that in the group 1 of exposed intensity index. The average scanning integrals of PCR amplified band in the group of bladder cancer patients and group 2 of exposed intensity index were both higher than that in the group 1 significantly. Workers in the groups of different exposed intensity indices were further stratified according to Papanicolau grades. In the group 2 of exposed intensity index, the average scanning integrals of PCR amplified band in the stratum of Papanicolau grade II and III were significantly higher than that in the strata of Papanicolau grade I. And in the group 3 of exposed intensity index, the positive rate of mutant p53 protein in the strata of Papanicolau grade III was higher than that in the strata of Papanicolau grade I significantly.
CONCLUSIONThe increase of exposed intensity may not only result in the positive rate of mutant p53 protein, but also the quantity of mutant p53 protein in serum within the low range of benzidine exposure. Once the exposed intensity was beyond that spectrum, the positive rate of mutant p53 protein in serum and the average scanning integrals of PCR amplified band were no longer enhanced with the increase of exposed intensity. There was tight correlation between Papanicolau grade of exfoliated urothelial cells and the positive rate or the quantity of mutant p53 protein for the higher benzidine exposure intensity.

OBJECTIVETo explore the effects of soothing liver and invigorating spleen recipes on lipopolysaccharide(LPS) induced hepatocyte inflammation of rats and TLR4/p38MAPK signal pathway.
METHODThe hepatocytes of SD rats were cultured and identified in vitro. The medicated serum of soothing liver and invigorating spleen recipes was prepared. The hepatocytes were treated with soothing liver and invigorating spleen recipes. Then Interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) expression in cultural supernatants were assayed by ELISA. The expressions of Toll-Like 4 (TLR4), p38 mitogen activated protein kinases (p38MAPK) and p-p38 mitogen-activated protein kinase (p-p38MAPK) were detected by Western blot.
RESULTThe rat medicated serum of soothing liver and invigorating spleen recipes was extracted for 2-3 mL. The purified rat hepatocytes were 1.5 x 10(8)-2.0 x 10(8). The cell viability was above 95% detected by Typan blue staining. The hepatocytes were identified by immumofluorescence assay. The detection of hepatocyte cultural supernatants: compared with that of the control group, IL-6 and TNF-α expression were increased in the LPS group (P < 0.01). While compared with that of the LPS group, the expressions of IL-6 and TNF-α were decreased after soothing liver and invigorating spleen recipes intervention (P < 0.01). The detection of hepatocyte proteins: compared with that of the control group, the protein expressions of p38MAPK, p-p38MAPK and TLR4 were all increased significantly in the LPS group (P < 0.01). Compared with that of the LPS group, the protein expressions of p38MAPK was decreased significantly in SB239063 group and it was also decreased in the soothing liver and invigorating spleen recipes group, but with no significant difference. Compared with that of the LPS group, p38MAPK expression was reduced significantly in the soothing liver and invigorating spleen recipes group and the SB239063 (p38MAPK pathway inhibitor) group (P < 0.01). TLR4 protein expression was decreased markedly in the soothing liver and invigorating spleen recipes group (P < 0.01) but had no difference between the SB239063 group and the LPS group.
CONCLUSIONThe soothing liver and invigorating spleen recipes may regulate hepatocyte inflammatory injury of rats through TLR4/p38MAPK signaling pathway.

OBJECTIVETo explore the effect of Shugan Jianpi Recipe (SJR) on LXRα/FAS signaling pathway mediated hepatocyte fatty deposits in nonalcoholic fatty liver disease (NAFLD) rats.
METHODSTotally 75 SPF grade male SD rats were randomly divided into 5 groups, i.e., the normal control group, the model group, the Shugan Recipe (SR) treatment groups, the Jianpi Recipe (JR) treatment group, and the SJR group. Except rats in the normal control group, the NAFLD rat model was duplicated using high fat diet (HFD). SR (Chaihu Shugan Powder) was administered to rats in the SR group. JR (Shenlin Baizhu Powder) was administered to rats in the JR group. SJR (Chaihu Shugan Powder plus Shenlin Baizhu Powder) was administered to rats in the SJR group. Changes of liver fat were analyzed using automatic biochemical analyzer. Liver cells were separated by low-speed centrifugation. Their activities and purities were identify using Typan blue and flow cytometry (FCM). Expression levels of LXRα and FAS mRNA in hepatocytes detected by Real-time quantitative PCR. Expression levels of LXRα and FAS protein were detected by Western blot.
RESULTS(1) Pathological results showed in the model group, hepatocytes were swollen with nucleus locating at the cell edge after oil red O staining; unequal sized small vacuoles could be seen inside cytoplasm. Some small vacuoles merged big vacuoles. All these indi- cated a NAFLD rat model was successfully established by high fat diet. Pathological structural changes could be impaired to some degree in all medicated groups, especially in the SR group. (2) Compared with the normal control group, expression levels of LXRα and FAS genes and proteins obviously increased in the model group (P < 0.01). Compared with the model group, their expression levels were obviously down-regulated in the JR group and the SR group (P < 0.01, P < 0.05).
CONCLUSIONSLXRα/FAS signaling pathway was an important signaling pathway for mediating lipid metabolism disorders of NAFLD rats. SJR could make hepatocyte fatty deposits tend to repair by adjusting the LXRα/FAS signaling pathway in NAFLD rats, which might be one of important mechanisms for SJR to prevent and cure NAFLD.
