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.

BACKGROUND:Traditional cel transplantation tracer methods require histological analysis and identification in vitro, which limits the clinical application of stem cel transplantation. So it is urgent to establish an in vivo noninvasive and repeatable tracer method. OBJECTIVE:To observe the effect of SPIO and DAPI double labeling on survival and proliferation of bone marrow mesenchymal stem cel s from macaques. METHODS:Bone marrow mesenchymal stem cel s were derived from bone marrow aspirates of healthy macaques using whole bone marrow adherence method. Then, the cel s were identified using flow cytometry detection. Bone marrow mesenchymal stem cel s were labeled using SPIO and DAPI. Fluorescent microscope was used to detect DAPI positive rate, and Prussian blue staining and transmission electron microscope were employed to measure SPIO positive rate. MTT assay was used to detect cel viability and proliferation. RESULTS AND CONCLUSION:Bone marrow mesenchymal stem cel s were successful y isolated from healthy macaques using the whole bone marrow adherence method, and the cel purity was up to 95.1%. SPIO and DAPI were both successful to label the bone marrow mesenchymal stem cel s with a positive rate of 95%-98%, but had no influence on cel viability and proliferation.

Objective To investigate the prevalence and influencing factors in senile cataract in Huzhou city.Methods 1 680 cases of healthy physical examination elderly population were selected as the research subjects in Huzhou city.To investigate the prevalence of cataract in the elderly population.The correlation of the prevalence of senile cataract,visual impairment and sex,age was studied.The correlation of the prevalence of senile cataract and diabetes,hypertension,smoking was analyzed.At the same time,Logistic regression analysis was used to analyze the influence factors of senile cataract.Results In 1 680 cases of elderly people,299 cases of cataract,the prevalence rate of cataract was 17.79%.With age increased,the prevalence of senile cataract was gradually increased.The preva-lence of cataract in female was 21.80%,which was higher than 15.82% in male,and the difference was statistically significant (χ2 =9.083,P <0.01).The visual acuity of senile cataract patients would increase with age.Moreover, the visual acuity of female patients was higher than that of male patients.The prevalence of cataract in diabetic group was 64.58%,which was higher than 17.89% in non -diabetes group,the difference was statistically significant (χ2 =65.457,P <0.01 ).The prevalence of cataract in hypertension group was 61.48%,which was higher than 14.31% in non -hypertension group,and the difference was statistically significant (χ2 =163.538,P <0.01).The prevalence of cataract in smoking group was 80.39%,which was higher than 16.94% in non - smoking group,the difference was statistically significant (χ2 =130.046,P <0.01).Logistic regression analysis showed that gender,age, diabetes,hypertension,smoking,and so on were the factors affecting the incidence of cataract in the elderly popula-tion.Conclusion The prevalence of cataract in the elderly population in Huzhou city need to pay attention to the local health department.

Programmed death-ligand 1 (PD-L1 ),which is highly expressed in NSCLC,can be divided into two categories:membrane PD-L1 and soluble PD-L1 .PD-L1 participates in tumor immune escape through combining with its receptor.PD-L1 immune checkpoint inhibitors have entered the phase Ⅰ studies and showed a good application prospect.It is also found that the sensitivity of PD-L1 immune checkpoint inhibitors is strongly associated with the expression of PD-L1 in tumor.Therefore,PD-L1 can be used as a biomarker to pre-dict its curative effect.
