Objective:To analyze the causes of microbial contamination in methadone hydrochloride oral solution used for the ma-intenance treatment of heroin addict in Guangxi and propose the relative countermeasures. Methods:The samples of methadone hydro-chloride oral solution were obtained from 10 maintenance treatment clinics, and then the microbial limit test and identification were per-formed,the content of preservative was detected and the relationship between the preservative content and microbial contamination was studied. Results:The total number of aerobe in the samples of methadone hydrochloride oral solution from the 10 clinics was all over the standard limit value of 100 cfu·ml-1 ,and the main contaminating germ was Burkholderia cepacia. The contents of sorbic acid were 78. 2％-98. 3％,the four batches with the lowest concentration of preservative were detected with higher total number of aerobe. Con-clusion:The microbial contamination in methadone hydrochloride oral solution from the 10 maintenance treatment clinics is severe,and the environment of medicine packaging, content of preservatives, packaging machine and storage conditions are the primary causes for the microbial contamination. To ensure drug quality safety, it is suggested that the environment cleanliness of medicine packaging be improved, suitable content of preservatives be added, packaging machine be clean, the products be stored in shade and the quality be tested regularly.

Dyslipidemia is a recognized risk factor for ischemic stroke. As an important component of lipids, lipoprotein(a) (Lp [a] ) was first found within the atherosclerotic plaques which is similar to the lipid body of the low-density lipoprotein cholesterol? Studies have showed that Lp (a) is involved in the formation of atherosclerosis and thrombosis through a variety of mechanisms, and then triggers cardio-cerebrovascular diseases. Identifying its relation with ischemic stroke and other risk factors may provide references for early prevention and treatment of ischemic stroke.

Objective:To analyze the relationship among hypertensive cardiac change,kidney disease and hyperten-sive retinopathy (HRP).Methods:A total of 100 patients with hypertension,who were diagnosed and treated in our hospital from Jan 2012 to Dec 2013,were enrolled,including 90 HRP patients (34 cases of class Ⅰ,49 cases of class Ⅱ,six cases of class Ⅲ and one case of class Ⅳ)and 10 cases with normal fundus (normal control group). Clinical data of all patients were analyzed,left ventricular mass index (LVMI),carotid intima-media thickness (IMT)and glomerular filtration rate (GFR)etc.were measured.Results:Compared with normal control group, there were significant thickening in IMT [(0.62±0.30)mm vs.(0.87±0.16)mm vs.(1.10±0.28)mm]in HRP class Ⅰ+Ⅱ group,class Ⅲ+Ⅳ group,the IMT of class Ⅲ+Ⅳ group was significantly thickened than that of class Ⅰ+Ⅱ group (P <0.01 all);Compared with normal control group,the incidence rates of cardiac dilation (0%vs.12.05% vs.71.43%)and kidney function damage (0% vs.24.10% vs.85.71%)significantly rose in HRP class Ⅰ+Ⅱ group,class Ⅲ+Ⅳ group,the incidence rates of cardiac dilation and kidney function damage in HRP class Ⅲ+Ⅳ group significantly rose than those of class Ⅰ+Ⅱ group (P <0.01 all).Conclusion:Severity of hyper-tension retinopathy is closely related to hypertensive cardiac dilation and kidney function damage.

Objective:To explore the cerebral hemodynamic changes of patients with hypertension complicated reti-nopathy.Methods:A total of 77 patients with hypertension complicated retinopathy were enrolled as study group, another 70 patients,who received physical examination during the same period and its results were normal,were treated as normal control group.Index changes of middle cerebral artery (MCA)and anterior cerebral artery (ACA)were compared between two groups,and hemodynamic difference of ophthalmic artery (OA)and central retinal artery (CRA)were recorded.Results:Compared with normal control group:① Mean velocity of MCA and ACA [(64.28±13.29)cm/s,(20.12±7.21)cm/s vs.(129.18±20.14)cm/s,(89.35±10.98)cm/s]signifi-cantly rose in study group ,P <0.01 all;②There were significant reductions in peak systolic velocity (PSV)and end-diastolic velocity (EDV)of OA and CRA,P <0.05 all,and resistance index significantly rose in all classes of study group (P <0.05 all);③There were significant reductions in mean blood flow velocity [(21.62±7.36)ml/s vs.(13.47±5.13)ml/s],maximum blood flow velocity and minimum blood flow velocity ,and significant rise in pulse wave velocity,peripheral resistance,critical pressure,vascular characteristic impedance [(17.35±5.36)kPa ·s-1 ·m-1 vs.(31.68±6.47)kPa· s-1 · m-1 ],and dynamic resistance [(30.59 ± 6.98)kPa· s-1 · m-1 vs. (64.48±12.38)kPa·s-1 ·m-1 ],in basilar artery in study group,P <0.01 all.Conclusion:In patients with hy-pertension complicated retinopathy,cerebral blood supply indexes reduce along with blood pressure rises,CRA blood flow changes can be regarded as a judging basis for disease course development,which deserves highly atten-tion for patients and physicians.

JAK/STAT is a central signaling pathway activated by cytokines binding with their respective receptors which can regulate cell proliferation,differentiation and apoptosis.Recent studies have suggested that abnormal signaling pathway with gene mutation and dysregulation plays an important role in the pathogenesis and progression of acute leukemia.The investigation of this pathway may provide novel target for therapies of acute leukemia.
