Objective To investigate the value of the wireless mobile information technology in pre-hospital and in-hospital emergency treatment of severe craniocerebral injury.Methods The clinical data of 55 severe craniocerebral injury patients with using wireless mobile information technology in ambulance from October 2010 to March 2012 (wireless group) and 50 severe craniocerebral injury patients without using wireless mobile information technology in ambulance from April 2009 to September 2010 (traditional group) were enrolled in this study.The scores of Glasgow coma scale,time from injury to being given the exact treatment,and survival rate were compared between two groups.Results The scores of GCS between two groups showed no significant difference(t =0.551,P> 0.05).The time from injury to being given the exact treatment in wireless group was significantly shorter than that in traditional group [(1.646 ± 0.499) h vs.(2.085 ±0.573) h,t =4.051,P<0.05].Comparing to traditional group,the survival rate in wireless group was significantly reduced [78.2% (43/55) vs.58.0% (29/50),x2 =4.057,P < 0.05].Conclusions Wireless mobile information technology using in pre-hospital enable in-hospital treatment in advance,shorten the waiting time to get the exact treatment.Wireless mobile information technology is the joint between pre-hospital and in-hospital and enhance the survival rate of severe craniocerebral injury.

4.Research advance in antitumor activities of artemisinin and its derivatives.
Acta Academiae Medicinae Sinicae 2013;35(4):466-471
Artemisinin and its derivatives are highly effective in fighting against malaria. Notably, these drugs have shown potent anti-timor activities by arresting cellular growth, enhancing apoptosis, inhibiting angiogenesis, and regulating the expression of tumor-associated genes, although the underlying mechanisms remain unclear.

OBJECTIVETo explore the clinical effect of Tripterygiitotorum (T II) combined with prednisone in treating patients with myasthenia gravis (MG) and the changes of immune function after treatment.
METHODSSixty-eight patients with MG were randomly divided into two groups, the 36 patients in the treated group were treated with T II plus prednisone and the 32 in the control group were treated with prednisone alone. The therapeutic effect, serum interleukin-6 (IL-6) and peripheral B lymphocyte levels were observed.
RESULTSThe therapeutic effect in the treated group was significantly higher than that in the control group (P < 0.05). There were significant decrease in serum IL-6 and peripheral B lymphocyte in both groups after treatment (P < 0.05), with the decrements more significant in the treated group (P < 0.05).
CONCLUSIONThe therapy of T II plus prednisone is superior to that of prednisone alone in treating MG, it has a more potent effect of immunosuppression.

Dingzhi Xiaowan is a widely used traditional Chinese medicine in treating depression, which is a similar formula of Kaixinsan. In this research, a rapid ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS(E)) method was established to analyze the metabolites of Dingzhi Xiaowan in depressive model rat plasma, bile, urine and feces. After we established Chronic unpredictable mild stress (CUMS) model rats and orally administrated Dingzhi Xiaowan, rat plasma, bile, urine and feces samples were collected and prepared. Using Waters Cortects UPLC C18 column (2.1 mm x 50 mm, 1.6 μm), acetonitrile-0.1% formic acid mobile phase gradient, these samples were analyzed and 33 metabolites of nine bioactive compounds were detected and tentatively identified by Metabolynx. Among the 33 metabolites, three metabolites were identified from plasma sample, three came from bile sample, and 27 metabolites were identified from urine and feces samples. This approach provided a rapid method for characterizing the metabolites of Dingzhi Xiaowan and gave the truly active structures and the action mechanism of their antidepressant effects.

7.Seroprevalence and molecular detection of leptospirosis from a dog shelter
Tropical Biomedicine 2016;33(2):276-284
A study on seroprevalence and molecular detection of canine leptospirosis was
carried out in a dog population (randomly selected
n
=80 dogs) from an animal shelter X. All
the dogs in Shelter X appeared clinically healthy. Eighty blood samples were obtained and
their serum were serologically examined using Microscopic Agglutination Test (MAT) against
10 Leptospira serovars. Plasma samples obtained were subjected to Polymerase Chain Reaction
(PCR) assay. Three out of 80 dogs (3.8%) tested positive for
L. bataviae
based on MAT at a
titer of 1:80. The seroprevalence of 9 other Leptospira serovars was not evident in this study.
All the dogs tested negative against leptospirosis with PCR assay. In conclusion, canine
leptospirosis was detected in dogs in this animal shelter.
L. bataviae
was identified as the
infecting serovar. To our knowledge, this is the second report of serovar Bataviae infection in
dogs in Malaysia. The 3 dogs in our study could possibly be a source of leptospiral infection
to other dogs and may shed the bacteria into the environment. This serovar is not available in
canine vaccination programs, therefore the dogs are not protected from this disease. Further
investigation is warranted to determine whether the infected dogs are carriers of this serovar.

OBJECTIVE:
To observe the proliferation of SW480 cells exposed to different concentrations of CoCl2, and to examine the expression of hypoxiainducible factor-1 alpha (HIF-1alpha) and heme oxygenase-1 (HO-1) during hypoxia to explore the chemotherapy resistance effect and role of HIF-1alpha and HO-1.
METHODS:
Methyl thiazolyl tetrazolium (MTF) method was used to detect the proliferation of SW480 cells in the presence of fluorouracil (FU). RT-PCR was applied to examine the expression of HIF-1alpha and HO-1 mRNA in hypoxia.
RESULTS:
SW480 cells were proliferated at a slow rate, and had a strong resistance to FU with the increase of CoCl2. RT-PCR showed that the up-regulated expression of HIF-1alpha and HO-1 mRNA was consistent with the dose-effect curve and time-effect curve.
CONCLUSION
The hypoxia induced by CoCl2 can inhibit the proliferation of SW480, and it can also decrease the sensitivity of the cell to FU. The mechanism is probably related to the up-regulated expression of HIF-1alpha and HO-1 mRNA.

OBJECTIVETo explore the risk factors of Parkinson disease (PD), interaction between family history of PD and other risk factors, as well as the relative strength of genetic factors over the vulnerability of PD.
METHODSOne 1:1 matched case-control study including 157 pairs of cases and controls was conducted in Qilu Hospital of Shandong University.
RESULTSConditional logistic regression analysis showed that family history of PD, mental labor, insecticide, alcohol drinking and history of depression all had positive relationship, while smoking had a negative relationship with PD. The AP (AB)s of family history of PD and insecticide, alcohol drinking, history of depression were 55.2%, 34.0%, 41.4% and the RERIs were 8.96, 3.31, 7.85 respectively. The heritability of PD patients' first degree relatives was 36.86% +/- 5.76%, and second degree relatives was 20.66% +/- 6.81%.
CONCLUSIONFamily history of PD had an additive model synergism on PD, coexisting with other risk factors. Genetic factors had a smaller action on PD than environmental factors.
