Objective To observe the clinical efficacy of Xuanfeitongfu method in treatment of severe pneumonia and to explore its clinical value in the management of severe pneumonia. Methods Totally,62 patients with severe pneumonia were randomly divided into the control group (n = 30) and the treatment group (n = 32). The control group was given cluster treatment,including oxygen cure,anti-infection and nutrition support and maintaining a stable internal environment and etc. The treatment group was treated with Tongfu decoction orally(one dose a day,a total of 5 days)on a basis of cluster treatment. The comparison was conducted in the 2 groups in the levels of C reaction protein,calcitonin,the change of blood gas analysis,the time of mechanical ventilation and the mortality of severe pneumonia in ICU at baseline and 3,5 days after treatment. Results The level of C-reactive protein,calcitonin,the change of blood gas analysis were statistically significant (P < 0.05). The time of mechanical ventilation and the mortality were better in the treatment group (P < 0.05). Conclusion Xuanfeitongfu method can effectively improve oxygenation ,assist the anti-infection effect ,reduce the time of mechanical ventilation and ICU retention time ,ultimately improve the outcome of severe pneumonia.

To investigate the effect of compound Chinese traditional medicine PC-SPES II I in inhibiting proliferation of human prostate cancer cell LNCaP based on the androgen receptor (AR) signaling pathway. The effect of PC-SPES II on LNCaP cell proliferation was detected by MTT assay. According to the findings, at the mass concentration of 180-1 440 mg x L(-1), PC-SPES II significantly inhibited the proliferation of LNCaP cells; the IC50 of PC-SPES II at 24 h and 48 h were 311.48, 199.01 mg x L(-1), respectively. The flow Cytometry detection showed 240 mg x L(-1) PC-SPES II arrested cells in G2/M phase, and an obvious apoptotic peak appeared before G0/G1 peak and rose over time. Meanwhile, Hoechst 33258 staining revealed apoptotic cellular morphology. Annexin V-FITC/PI staining manifested an increase in apoptotic cell ratio at the PC-SPES II concentration of 480 mg x L(-1) in a dose dependent manner. The prostate specific antigen (PSA) secretion of LNCaP cells was tested by PSA ELISA kit. Besides, compared with 25 mg x L(-1) Bic, 480 mg x L(-1) PC-SPES II significantly reduced the cell secretion of PSA. The AR and PSA mRNA and protein expressions were detected by qRT-PCR and Western blot. According to the results, after the induction of LNCaP cells with synthetic androgen 25 μg x L(-1) R1881, 240-480 mg x L(-1) PC-SPES II notably down-regulated the AR and PSA mRNA and protein expressions and inhibited the translocation of AR from cytoplasm to nucleus. In summary, PC-SPES II significantly can inhibit the in vitro proliferation of LNCaP cells and arrest cell cycle arrest in G2/M phase. Its mechanism may be associated with the down-regulation of the AR and PSA expressions and the inhibition of AR nuclear translocation.

Objective To observe effects of problem-based learning(PBL) combined with case-based study (CBS)teaching mode in clinical teaching in intensive care unit(ICU). Methods Students from ICU of Fangcun Branch of Guangdong Provincial Hospital of Traditional Chinese Medicine from March 2011 to February 2012 were divided into treatment group (31 cases, with PBL combined with CBS teaching mode) and control group (34 cases, with the traditional teaching mode). Scores of two groups were compared and analyzed and questionnaire survey was conducted in treatment group. Data were processed by SPSS 13.0 statistical software. Measurement data were compared by t-test and data of heterogeneous variance were compared by rank-sum test. Results Treatment group achieved better scores ((85.26 ±5.96) in theory examination and (80.59 ±7.33) in case-analyzing examination) compared with those of control group ((79.17 ±7.31) in theory examination and (76.02 ±9.27) in case-analyzing examination)(P<0.05). PBL combined with CBS teaching mode can stimulate learning interests but it was lack of systematization; most students did not volunteer to speak. Conclusion PBL combined with CBS teaching mode has certain advantages in ICU clinical teaching.

Objective To explore the influence of 30 day feeding test of health food containing caffeine on the physiological state of SD rat.Methods SD rats were randomly divided into five groups according weight :three health food containing caffeine(1.64,3.28,6.57 g/kg),one health food containing reduced caffeine (6.48 g/kg)and the control group. Haematological and biochemical parameters were measured at the end of experiment,and main organ tissue analysis was also performed.Results Weight at the end of 4 week,weight after absolute diet,total weight increased,and total food consumption and food consumption at the end of 4 week in 6.57 g/kg groups of male rats were decreased compared with the control group (P <0.05 ).Conclusion In comparison with 6.48 g/kg group,all those changes may be caused by overhigh caffeine in 6.48 g/kg group.

The purpose of this study was to explore the significance of abnormal karyotype in diagnosis and prognosis estimation of myelodysplastic syndrome (MDS). Chromosome analysis were performed in 306 cases of MDS using the short-term culture of bone marrow cell and G-banding technique, and in partial cases FISH technique was used for this analysis. 93 out of 306 cases were followed up. The results showed that 144 cases (47.1%) had clonal chromosome aberrations. The most common chromosomal aberrations included +8, translocation, complex or high complex karyotype, -7/7q-, 20q-/-20, trisomy 1 or partial trisomy 1, +11/+11q-, -9/9q-, +9/9q+, -Y, dup(1q), +21. The rate of abnormal karyotype in refractory anemia with erythroblasts (RAEB) and refractory anemia with erythroblasts-transformation (RAEBT) were much higher than in refractory anemia (RA) and refractory anemia with sideroblasts (RAS) (P < 0.05). The rate of abnormal karyotype among those cases with mutagen contact history were higher than those in cases without mutagen contact history. The patients with abnormal karyotype had a mean survival time much shorter than patients with normal karyotype (P < 0.005) and had a higher risk transforming into acute leukemia (P < 0.05). The worst outcome was observed in those patients with a complex or high complex karyotype, -7/7q- and trisomy 11. In conclusion, MDS is highly heterogeneous disorders and karyotype analysis is helpful for its diagnosis, treatment selection and prognosis estimation.

Malignant cancer is the leading cause of death in man, exceeding cerebrovascular disease and heart disease. More than half of the total mortality due to malignant cancer is from lung, liver, intestinal and gastric cancer. Chemotherapy is one of the effective treatments for cancer. However, the great majority of Western anticancer medicines have considerable side effects. Herbal medicines offer many more advantages than synthesized compounds because they are made from purely natural compounds and have less adverse effects. However, the single administration methods used as standard in herbal medicine, and deficient drug targeting, severely limit their anticancer activity. Single-walled carbon nanotubes (SWNTs) can be used as drug carriers. They have been modified to form Chinese anticancer medicine-SWNT compounds which can specifically target tumors, thereby significantly increasing the therapeutic effectiveness of these medicines. Water-soluble SWNTs have high stability. As a drug carrier, SWNTs functional modification of the anticancer medicine may improve the targeting and killing of tumor cells. SWNTs have been attached to the Chinese antitumor medicines paclitaxel and plumbagin and have achieved excellent therapeutic effects. Furthermore, choosing the best administration methods such as internal iliac arterial infusion, intravesical infusion and embedment of a hypodermic chemotherapeutic pump, may also improve the anticancer effects of Chinese medicine.

AIMTo determine the effect of soman on stress induced hyperthermia and the influence of central and peripheral cholinergic antagonists.

METHODSEffects of subcutaneous injection of soman, scopolamine, methylscopolamine and pyridostigmine on stress-induced hyperthermia were observed in rats by radio telemetry in an open-field environment. Plasma cholinesterase (ChE) activity was measured by a spectrophotometry.

RESULTS(1) Core temperature of the control group increased by 0.96 degrees C when exposed to open-field, whereas core temperature only increased by 0.55 degrees C in soman treated animals. Scopolamine, a central cholinergic antagonist, nearly abolished inhibitory effects of soman on core temperature when exposed to open-field. Methylscopolamine, a peripheral cholinergic antagonist, coadministered with soman reduced significantly the hyperthermic response to open-field exposure compared with rats dosed with soman. (2) Pyridostigmine, a peripheral anti-ChE agent that caused a 52% decrease in plasma ChE activity led to a significant enhancement of the hyperthermic response to open-field exposure. Methyl scopolamine nearly abolished the effects of pyridostigmine on stress-induced hyperthermia response.

CONCLUSIONInhibitory effect of soman on the open field hyperthermia suggested that soman treatment hampered the ability of the rat to develop a normal hyperthermic response when placed in the open-field environment. Its inhibitory effects were mediated primarily through a central muscarinic pathway. In addition, peripheral cholinergic nerve was involved in the control of stress hyperthermic response.

OBJECTIVETo investigate the value of application of mandibular outer cortex as bone graft by comparing its bone absorption with cranial outer cortex.

METHODS8 minitype grown-up pigs at the age of 8 - 12 months underwent surgery of taking out the same size (2.5 cm x 1.0 cm) of outer cortex from mandible and craninium. The volume of the outer cortex was measured by volume-displacement method. Then the outer cortex of mandible and cranium were onlay grafted to the each side of the pig snout, respectively. 12 weeks later, 2 pigs were randomly selected for histological examination. The other 6 pigs were killed 24 weeks after surgery for measurement of the bone graft volume and histologic examination.

RESULTSThe bone graft absorption rate was (41 +/- 5)% for mandibular outer cortex and (46 +/- 12)% for cranial outer cortex, showing no significant difference between them (P = 0.51). The histologic examination results also had no marked difference in the bony healing and reforming between the two graft.

CONCLUSIONSMandibular outer cortex is a good donor site for onlay bone graft in craniofacial region.
