Ischemic stroke is one of the major diseases of causing adult disability and death.Age,sex,smoking,hypertension,and diabetes,etc.are the risk factors for ischemic stroke,but they can only partially explain the reasons of stroke onset.Twins,families,and single-gene genetic stroke studies have shown that ischemic stroke has obvious genetic predisposition.In recent years,genomics has made remarkable progress in ischemic stroke study and has shown that many new single nucleotide polymorphisms or genes are associated with ischemic stroke and its risk factors.However,the contribution of these genetic genes for ischemic stroke is still too small and the repetitive studies are needed for further confirmation.

Differed from the elderly patients with lung cancer,the younger patients with lung cancer,less than 50 years old,present unique clinical features.Recently,the incidence of lung cancer in young people has shown a rising trend,making the research on this field more valuable.At present,molecular targeted therapy is one of the most popular areas of non-small-cell lung cancer (NSCLC),and researches are focused on the epidermal growth factor receptor (EGFR) and echinoderm microtubule associated protein like4-anaplastic lymphoma kinase (EML4-ALK).In addition,the previous researches revealed the differences between the young and elderly patients with lung cancer on molecular genetics and prognosis,so the researches on prognostic factors for young patients with lung cancer are of great clinical significance.The present paper will focus on the aspects of pathogenesis,molecular genetics and prognosis in young patients with lung cancer.

Objective: To observe the clinical efficacy of warm needling moxibustion plus Mulligan dynamic joint mobilization for cervical radiculopathy. Methods: A total of 60 cases with cervical radiculopathy were randomly divided into group A, group B and group C by random digital table, 20 cases in each group. The patients in three groups were treated with similar warm needling moxibustion. Group A only received warm needling moxibustion; group B was treated with warm needling moxibustion plus Mulligan dynamic joint mobilization; group C was treated with warm needling moxibustion plus cervical traction. Before the treatment and after 12 sessions of treatment, the patients in the three groups were assessed for score of pain and range of motion (ROM). Results: By 12 sessions of the treatments, the scores of pain were obviously decreased in the three groups, with statistical significances (all P<0.05), and the pain scores of group B and group C were significantly different from the score of group A (both P<0.05). ROM of the neck was increased than before the treatment in the three groups, with statistical significances (all P<0.05), and the ROM of the neck of group B was significantly different from those of group A and group C (both P<0.05). Conclusion: Warm needling moxibustion plus Mulligan dynamic joint mobilization can effectively improve the neck ROM and relieve pain in patients with cervical radiculopathy.

Objective The coronary slow flow phenomenon (CSFP) is a coronary artery disease with a benign course,but its pathological mechanisms are not yet fully understood.The purpose of this controlled study was to investigate the cellular content of blood in patients diagnosed with CSFP and the relationship of this with coronary flow rates.Methods Coronary angiographies of 3368 patients were selected to assess thrombolysis in myocardial infarction (TIMI) frame count (TFC) values.Seventy eight of them had CSFP,and their demographic and laboratory findings were compared with 61 patients with normal coronary flow.Results Patients'demographic characteristics were similar in both two groups.Mean corrected TFC (cTFC) values were significantly elevated in CSFP patients (P ＜ 0.001).Furthermore,hematocrit and hemoglobin values,and eosinophil and basophil counts of the CSFP patients were significantly elevated compared with the values obtained in the control group (P =0.005,P =0.047,P =0.001 and P =0.002).The increase observed in hematocrit and eosinophil levels showed significant correlations with increased TFC values (r =0.288 and r =0.217).Conclusion Significant changes have been observed in the cellular composition of blood in patients diagnosed with CSFP as compared to the patients with normal coronary blood flow.The increases inhematocrit levels and in the eosinophil and basophil counts may have direct or indirect effects on the rate of coronary blood flow.

Objective To study the telomerase activity in the tissue adjacent to bladder cancer and to investigate its clinical significance. Methods Telomerase activity was detected with telomeric repeat amplification PCR (TRAP) assay. The telomerase activity in the tissue adjacent to bladder cancer was evaluated. Results Telomerase activity was positive in the tissue samples adjacent to bladder cancer in 10 of the 24 cases(42%). Telomerase activity in the adjacent tissue has been related with the tumour grades and stages. The tumour recurrence was also related with the telomerase activity in the adjacent tissue. Conclusions The detection of telomerase activity in the tissue adjacent to bladder cancer could be a prognostic marker for bladder tumor recurrence.
