Objective:To establish a quantitative method for determination of CK19 mRNA with TaqMan real time quantitative RT-PCR.Methods: A 230 bp fragment of CK19 mRNA was amplified from the total RNA of gastric cancer cells using RT-PCR methods and was introduced into pMD 18-T Simple vector.The plasmid was purified and the fluorescent standard PCR product was prepared.The expression levels of CK19 mRNA in standard PCR product,5 tumor tissue specimens and 30 healthy subjects were observed.Results: A 230 bp fragment of CK19 mRNA was successfully cloned into the pMD 18-T Simple vector and was verified by sequence analysis.A stable standard for detection of CK19 mRNA was established,that is,when C_(T) was set within 35 cycles,negative specimen was defined when the result was lower than 100 copies.Conclusion: TaqMan real time quantitative RT-PCR is stable and reliable in quantitative detection of CK19 mRNA in peripheral blood.

The fetal period is the critical time in the development of various organs.The changes in the intrauterine growth environment can cause fetal and neonatal multiple organ system underdevelopment and damage,which is also closely related to the adult diseases,including nervous system damage (such as brain development disorders,functional abnormalities and cerebral palsy,etc.),cardiovascular system damage(such as coronary heart disease,high blood pressure,etc.),growth disorders and metabolic disorders(such as insulin resistance,type Ⅱ diabetes,obesity,growth and development disorders),urinary system damage (such as interstitial renal disease,renal hypertension,etc.),respiratory system damage(such as respiratory distress syndrome,bronchial dysplasia,etc.),etc.In this paper,we introduced this to help clinicians to understand and strengthen the intervention measures to improve the quality of life.

Objective To investigate the effects of ?-aescin on nuclear factor-?B (NF-?B) activities and tumor necrosis factor-? (TNF-?) protein expression in the rat brain tissue following acute traumatic brain injury (TBI). Methods A total of 62 SD rats were subjected to a lateral cortical impact injury caused by a free-falling object and divided randomly into four groups, ie, sham operation group (Group A), injury group (Group B), ?-aescin treatment group (Group C) and pyrrolidine dithocarbamate (PDTC) treatment group (Group D). Group C was administered with ?-aescin and Group D treated with PDTC immediately after injury. A series of brain samples were obtained directly 6, 24 hours and three days respectively after operation in four groups. The NF-?B activation of rat brain was determined by electrophoretic mobility shift assay (EMSA) and the levels of TNF-? protein in rat brain measured by radio-immunoassay (RIA). In the meantime, the water content of rat brain was measured and pathomorphological observation carried out. Results Compared with Group A, NF-?B activities, the levels of TNF-? protein and the water content of the rat brain were significantly increased (P

Parenteral nutrition associated cholestasis (PNAC) mainly occurs in children. Currently identified risk factors include premature infants, lack of enteral feeding, repeated infections, and toxicity or nutrient deficiency of parenteral nutrition solution. Recent studies have shown that nuclear receptor-mediated bile acid transporter may be the key site of PNAC pathogenesis, in which some cytokines play important roles. New anti-cholestatic therapy based on the regulation of expression of these molecules may prevent end-stage liver disease caused by PNAC.

Age-related macular degeneration(AMD) is a macular disease and its incidence is gradually increasing with age.It is thought that its pathogenesis is related to the age,heredity,smoking,diet,oxidative stress,immune inflammation reaction and cardiovascular disease and so on.Oxidative stress is closely related to AMD.Antioxidant therapy provides a new strategy for the prevention and treatment of AMD.Also,it provides a new way to alleviate and prevent AMD.

Objective To investigate the effect of combination therapy with cognitive behavior on the quality of life of patients with gastroduodenal ulcer.Methods The patients with gastroduodenal ulcer treated in our hospital from April 2015 to April 2017 were randomly divided into intervention group and control group according to the order of treatment.Both groups were treated with bismuth-containing quadruple therapy and routine nursing was performed.The intervention group received cognitive behavior on this basis.SF-36 scale was used to evaluate the quality of life of the two groups of patients, and the prognosis of the patients was evaluated.The patient satisfaction was investigated by the self-designed questionnaire of patient satisfaction questionnaire.The clinical efficacy, treatment compliance, quality of life improvement, prognosis and satisfaction were compared between the two groups.Results The total effective rate was 96.67%(58/60) in the intervention group and 81.67%(49/60) in the control group.The total effective rate of the intervention group was significantly higher than that of the control group(P<0.05).The scores of SF-36 scale in the intervention group were higher than those in the control group(P<0.05).The incidence of complications in the intervention group was lower than that in the control group, and the satisfaction rate was higher than that of the control group(P<0.05).Conclusion Cognitive behavioral intervention combined with bismuth quadruple therapy for gastroduodenal ulcer can improve the patient's compliance and efficacy, significantly improve the quality of life of patients, improve patient satisfaction, with clinical application value.

AIM: To study the efficacy and safety of Ultra Q- YAG vitreolysis for vitreous floaters.
METHODS: Retrospective case series study. From September 2014 to May 2015 in Beijing Aier - Intech Eye Hospital, 263 cases (340 eyes) with vitreous floaters were involved. All patients underwent visual acuity, intraocular pressure, slit lamp, mydriatic fundus, B ultrasonic examination, and recorded the form of a vitreous opacity excluded pathological fundus lesions. All the patients were divided into two groups: Group A (<30 years old) 78 cases (82 eyes); the morphology of vitreous opacity were dot, filiform and mesh. Group B ( > 45 years old), 185 cases (258 eyes), the morphology of vitreous opacity was Weiss ring, translucent flocculent clouds or dense fibrous membrane. Patients in 30 - 45 years old were eliminated because of the untypical opacity factor. The treatment was done by the same physician. Vision changes was analyzed before and after the treatment.
RESULTS: Questionnaire survey was done. According to the scores of the questionnaires, patients were divided into 3 groups: no improvement ( 1 - 2 points), partial improvement (3-5 points), significant improvement (6-10 points ). At 1mo after treatment, Group A: no improvement in 9 eyes (11. 0%), partial improvement in 57 eyes (69. 5%) and significant improvement in 16 eyes (19. 5%); Group B: no improvement in 0 eyes, partial improvement in 23 eyes ( 8. 9%) and significant improvement in 235 eyes (91. 1%); all the patients had no complications.
CONCLUSION: The treatment with YAG vitreolysis for vitreous floaters is safe and effective, especially for the patients more than 45 years old whose vitreous floaters caused by posterior vitreous detachment.

Objective To investigate the span and frequency of physical symptoms of panic attack in patients with panic disorder.Methods Panic symptoms presented at the time of panic attacks were assessed and categorized in forty-eight consecutive outpatients with panic disorder during August 2000 to November 2002.Results Palpitations (44/48,91.7%), shortness of breath (36/48,75.0%), sweating (34/48,70.8%), feel suffocated (33/48,68.8%), faint (31/48,64.6%), dizziness (27/48,56.3%) and fear of dying (27/48,56.3%) were the most frequent symptoms reported by the patients with panic disorder. If categorized according to system, the most frequent symptoms were presented in cardiovascular, neurological, respiratory and autonomic nervous systems of patients with panic disorder.Conclusions Physical symptoms varies when panic attack occurs. Panic disorder was often misdiagnosed and underdiagnosed because of wide and non-specific spectrum of physical symptoms.
