Currently, about 300 million people worldwide are affected by asthma. Most of these sufferers inhale immunosuppressants (ie corticosteroids) and beta-adrenergic receptor agonists for their asthma treatment. However, about 5%-10% of patients of asthma have poor response to such treatment. Investigation of kinase signaling pathway and nuclear transcription factor as a target molecule in the treatment of allergic asthma has been the concern of scholars home and abroad. This paper reviewed inhibitors of kinase signaling pathway and nuclear transcription factors for the treatment of asthma.

The method of acupuncture combined with rehabilitation training in the treatment of shoulder hand syndrome after stroke is reliablet, quick, with simple operation and less adverse reactions. Among them, characteristic acupuncture could focus on the targeted points with obvious effect than ordinary acupuncture, and the combination with rehabilitation training could greatly improve the curative effect. However, there still exist some problems in the current research, such as the difficulty of conducting blind clinical trials of acupuncture therapy; the lack of follow-up data in the evaluation of curative effect, the uncertainty of long-term curative effect; the small sample size of clinical research, etc., so multi-centered and large sample RCT research are still needed.

Objective To detect the antibodies against recombinant chlamydial plasmid-encoded protein 3(rPgp3),chlamydial protease-like activity factor(rCPAF),Ct143 encoded protein(rCT143), Ct101 encoded protein(rCT101),Ct694 encoded protein(rCT694),Ct813 encoded protein(rCT813), Chlamydia membrane protein A(rIncA),Ct875 encoded protein(rCT875),major outer membrane protein (rMOMP)and heat shock protein 60( rHsp60)in serum samples collected form patients with urogenital Chlamydia trachomatis(Ct)infection and to evaluate the antigenicity of those proteins. Methods The re-combinant plasmids expressing the 10 proteins and a blank plasmid were transformed into E. coli BL21 strains,respectively. The transformed E. coli BL21 strains were induced by isopropyl β-D-1-thiogalactopyr-anoside(IPTG)to express recombinant proteins. The glutathione pre-coated 96-well ELISA plates were coa-ted with lysates. Serum samples were collected from 50 patients with Ct infection and 10 patients without Ct infection. ELISA was performed to detect the antibodies against 10 recombinant proteins. Results The anti-bodies against rPgp3,rCPAF,rCT143,rCT101,rCT694,rCT875,rCT813,rMOMP,rIncA and rHsp60 proteins were respectively detected in 44 cases(88% ),38 cases(76% ),37 cases(74% ),36 cases (72% ),33 cases(66% ),31 cases(62% ),30 cases(60% ),26 cases(52% ),24 cases(48% )and 17 cases(34% )out of 50 serum samples. No antibodies against 10 recombinant proteins were detected in the serum samples collected from patients without Ct infection. Conclusion The rPgp3 protein showed the strongest antigenicity among all of the studied proteins,followed by rCPAF and rCT143 proteins. The rHsp60 protein showed the lowest antigenicity.

Objective To detect antibodies against chlamydial plasmid-encoded protein 3 (Pgp3),outer membrane complex protein B C-terminal peptide (OmcBc),CT841 protein and heat shock protein 60 (HSP60) in the sera of patients with urogenital Chlamydia trachomatis infection.Methods Recombinant plasmids encoding the aforementioned four proteins and an empty plasmid were transformed into Escherichia coli separately followed by 2-hour isopropyl-1-thio-β-galactopyranoside (IPTG) induction and cell lysis.The expressed proteins were purified with glutathione magnetic beads and then used to coat 96-well enzyme-linked immunosorbent assay (ELISA) plates precoated by glutathione.Serum samples were collected from 20 patients with and 20 clients without urogenital C.trachomatis infection attending the sexually transmitted disease (STD) clinic of Tianjin Medical University General Hospital.ELISA with the expressed protein-coated plates was adopted to detect antibodies against these proteins in the serum samples.Results Of the 20 serum samples from C.trachomatis-infected patients,14 (70%)had anti-Pgp3 antibody,9 (45%) anti-OmcBc antibody,8 (40%) anti-CT841 antibody,and 5 (25%) anti-HSP60 antibody.Meanwhile,no antibody was detected in any of the serum samples from uninfected clients except for one with anti-HSP60 antibody.Conclusions Of the four studied C.trachomatis proteins,Pgp3 appears to have the strongest antigenicity with the highest antibody-detection rate,while HSP60 exhibits the weakest antigenicity with the lowest antibody-detection rate.

Objective To analyse the clinical features,imaging characteristics diversity of deep cerebral veins thrombosis (DCVT).Methods From 2004 to 2013,6 patients diagnosed as DCVT were recorded and a retrospective review of the cases were undertaken for the purpose of this analysis.Results Among the 6 patients with DCVT,4 were male and 2 were female,aged from 28 to 69 years old.The disease duration of 4 cases ranged from 2 to 7 days,remnants were 20 days and 3 months respectively.The first symptoms of 4 cases were headache,1 was feeblemindedness,and the other was hemiplegia.The secondary symptoms were disturbance of consciousness,apathy,diplopia and non-infectious fever.Non-contrast computed tomography showed low signal in the bilateral thalamus in four patients,high signal in the transverse sinus and straight sinus in one patient and high signal in torcular in one patient.Abnormal signal was found in bilateral thalamus on magnetic resonance imaging in all patients and some of them had abnormal signal in the mesencephalon or basal ganglia.The patients were definitely diagnosed as DCVT by magnetic resonance venography (MRV) or digital subtraction angiography (DSA).Among them,2 patients were confirmed by brain biopsy.Four patients were followed up with good outcome and 2 were lost to follow-up.Conclusions The clinical manifestations of DCVT are not specific.For acute-onset DCVT patients,the first symptoms are always headache and vomiting,while the main symptoms are declined cognition and slow reaction for chronic-onset ones.Along with the progress,the main symptoms of DCVT are disturbance of consciousness,psychiatric symptoms and intracranial hypertension.Changes in the bilateral thalamus and basal ganglia are especially main characteristics which are easily misdiagnosed as brain tumor according to the images.DCVT can be definitely diagnosed by no signal of deep cerebral veins on MRV or DSA.

Objective To explore the impact of the different antiepileptic drugs on cognitive function in patients with epilepsy.Methods There are 280 cases of patients with epilepsy from Department of Neurology in our hospital out-patient and hospitalization, while 32 cases are the normal control group. The patients were randomly divided into groups of topiramate, carbamazepine and sodium valproate group and topiramate plus valproate combined therapy group. Wechsler Memory Scale was used by the patients before and after treatment to assess cognitive function, and compared with the normal group. Results Carbamazepine monotherapy group and the valproate group were no significant difference in areas of cognitive function belong to the normal level; Topiramate monotherapy group cognitive function was significantly lower than normal, the joint drug group was the most of the lower level of cognitive function. Conclusion Carbamazepine and valproate monotherapy were applied had the minor cognitive impairment, combination therapy of epilepsy in patients had severe cognitive impairment.
