1.Application of Next-generation Sequencing Techniques in the Dynamics of HIV-1 Quasispecies.
Chinese Journal of Virology 2015;31(5):573-578
In the last decade, next-generation sequencing (NGS) technology, which is characterized by being high-throughput, rapid, sensitive, and accurate, has developed rapidly. Main components of NGS are platforms: 454 sequencing; illumina sequencing; ion torrent sequencing; SOLID sequencing. NGS is used widely for the human immunodeficiency virus (HIV)-1. In this review, we focus on applications of the dynamics of HIV-1 quasispecies.

2.Study on the reliability and validity of the Chinese version of the Nottingham Assessment of Functional Footcare
Chinese Journal of Practical Nursing 2015;31(6):450-453
Objective The study aimed to explore the reliability and validity of the Chinese version of the Nottingham Assessment of Functional Footcare (NAFF) in investigating the footcare behavior's level in patients with high risk of diabetic foot.Methods According to Bradley's principle,NAFF was converted into the Chinese version scale,then it was applied to 211 cases of patients with high risk of type 2 diabetic foot,and the reliability and validity of foot care be-havior scores were analyzed.Results In the Chinese version scale,the Cronbach's alpha coefficient was 0.77,test-retest reliability was 0.74.Content validity,ICVI was 0.80 to 1.00,S-CVI/Ave was 0.96,and the adjusted value of kappa was 0.75 to 1.00.Conclusions The questionnaire has been tested to have good reliability and validity.The NAFF possesses certain value in the clinical application and could be suitable for Chinese patients with high risk of type 2 diabetic foot.

The intestinal type of lung adenocarcinoma is a very rare subtype of lung adenocarcinoma, presenting with pulmonary symptoms, but without any gastrointestinal symptoms and pathological changes. The author found 1 case of double primary lung adenocarcinoma of the left lung, which was confirmed by surgery pathology, one for lung adenocarcinoma, one for a rare type of intestinal adenocarcinoma. This paper reviews the relevant literatures of the diagnosis and treatment of this case.
4.The effect of PKCζinhibitor on the proliferation and invasion of skin squamous carcinoma cell line A-431
Tianjin Medical Journal 2017;45(6):566-570
Objective To investigate the effect of protein kinase C (PKC)ζinhibitor T5450996 on the proliferation and invasion of skin squamous carcinoma cell line A-431. Methods PKCζinhibitor T5450996 was screened through Z′-LYTE?kit. Cell proliferation assay and cell cycle analysis were used to observe the effects of T5450996 on the proliferation of skin squamous carcinoma A-431 cells. Scratch assay and invasion assay were used to explore the effects of T5450996 on the migration and invasion of skin squamous carcinoma A-431 cells. Results The PKCζinhibitor T5450996 can inhibit the activity of PKCζkinase, and the IC50 value of T5450996 was about 35μmol/L. Compared to the control group, 35μmol/L and 70 μmol/L concentrations of T5450996 significantly suppressed the proliferation of A-431 cells and blocked the cell cycle of A-431 cells. The results of scratch assay and invasion assay indicated that the migration and invasion capacities of A-431 cells were markedly impaired after the treatments with 35μmol/L and 70μmol/L concentrations of T5450996 (P<0.05). However, 20μmol/L concentration of T5450996 showed no significant effect (P>0.05). Conclusion PKCζinhibitor T5450996 significantly inhibits the proliferation and invasion capacities of skin squamous carcinoma cell line A-431, and which may be a small molecular inhibitor with potential applications in the future.
5.Expression of P53 protein in epithelial ovarian cancer and clinical value
Journal of Xi'an Jiaotong University(Medical Sciences) 1982;0(04):-
Objective To study the relationship between P53 and carcinogenesis of epithelial ovarian cancer. Methods Immunohistochemistry was used to evaluate the expression level of P53 protein in 74 cases of epithelial ovarian cancer. Results The expression level of P53 protein was higher in G1 and G2 groups (90.62%) than in G3 group (66.67%, P 0.05). Conclusion P53 may play a role in the pathogenesis of epithelial ovarian cancer.

Objective T_O analyze the electrophysiological features of shoulder-hand syndrome(SHS)fol- lowing stroke and investigate the relationships between peripheral nerve damage and the factors causing SHS.Meth- ods Fifty-eight stroke patients were divided into an SHS group(39 patients with shoulder-hand syndrome)and a model group(19 patients without shoulder-hand syndrome).Standard sensory and motor nerve conduction studies were performed with 58 of the patients,including sensory nerve conduction velocity(SCV),amplitude of the sensory nerve action potential(SNAP),distal motor latency(DMI)and the amplitude of the compound muscle action poten- tial(CMAP)of the median nerve.A needle electromyogram(EMG)test was performed on the abductor pollicis of the affected side with both groups.Results The needle EMG showed abnormal insertion potential,fibrillation po- tential and positive sharp waves in all 39 cases of the SHS group,which was significantly higher than in the model group.The amplitude of the sensory nerve action potential(7.77?4.34 mV)and the amplitude of the compound muscle action potential(10.13?3.15 mV)were significantly lower than those of the model group.Abnormal ampli- tude was more severe in sensory nerves than in motor nerves.Conclusion Peripheral nerve damage was found in the shoulder-hand syndrome patients,and this damage was mainly the dystrophy of axonal neuropathy.The damage severity was more in sensory nerves than in motor nerves.The study could offer an useful clue of prevention and treat- ment of shoulder-hand syndrome.

The metabolism study of radiolabeled drugs plays an important role in the development of new drugs. It provides information on drug absorption, metabolism, tissue distribution and excretion, and plays an irreplaceable role in the metabolite safety evaluation and mass balance of new drugs. The new guidance draft on clinical trials of radiolabeled drugs recently released by the US FDA puts forward higher standards and has been widely concerned by the industry. In recent years, in the research and development of new drugs in China, 14C labeled drugs have been used to carry out clinical metabolism studies, which has overcome key technical bottlenecks and accumulated experience. This paper summarizes the above research progress, analyzes the existing problems, and preliminarily looks forward to the future technological development and application.

ObjectiveTo observe the effect of nursing interventions on improvement of psychological actions and quality of life of patients with Alzheimer disease. Methods50 patients with senile dementia diagnosed in our hospital were chosen.They were divided into the observation group and the control group with 25 patients in each group.All patients were taken with AD routine nursing care after admission.The observation group was taken with rehabilitation nursing interventions based on AD routine nursing care.The mini-mental state examination (MMSE)and the daily life ability scale (ADL)were used to evaluate the quality of life after nursing intervention. ResultsThe patients' MMSE score in the observation group was significantly higher than the control group,the difference was statistically significant.The ADL score of the observation group was significantly lower than the control group,the difference was statistically significant. ConclusionsThe use of integrated care intervention can significantly improve the cognitive function in AD patients,and improve daily living ability and quality of life significantly.
