Chongqing Medicine 2017;46(6):777-779
Objective To detect the expression of YB-1 and to research the relationship in the occurrence and development in the cervical squamous carcinoma(SCC) tissues.Methods Immunohistochemistry(IHC) envision was used to detect the expression of chronic cervicitis,CIN Ⅰ,CIN Ⅱ-Ⅲ and SCC.The relationship of YB-1 in the clinical pathological parameters of SCC were analyzed.Results YB-1 was mainly located in the nucleus in squamous cell,sometimes in the cytoplasm.The YB-1 protein did not expression in chronic cervicitis.In CIN Ⅰ,CIN Ⅱ-lⅢ and SCC,the positive expression had a gradual increasing trend.The expression of YB-1 was satistically significant in four groups (P<0.05).The chronic cervicitis group,CIN Ⅰ groupCIN Ⅱ-Ⅲ group compared with the SCC group restivelly,the difference was statistically significant (P<0.05).From spearman rank correlation analysis:the expression of YB-1 was positively correlated with the degree of cervical lesions (P< 0.05).In the cervical squamous carcinoma group,the expression of YB-1 was not associated with clinical pathological index of SCC patients(P>0.05).Conclusion The change of the quantity of YB-1 protein is closely related to cervical squamous cell carcinoma.

Adenoid hypertrophy is a disease that mostly occurs among children of 3-5 years old. It is caused by repeated inflammation and infection of nasopharynx and its adjoin parts, or the adenoid itself, which will finally leads to pathological hyperplasia of adenoid. With so much information we have acquired about this disease, its specific mechanism remains unknown. In recent years, some researches have indicated that adenoid hypertrophy may have something to do with extra-gastroesophageal reflux, in which pepsin plays a very important role, and pepsin will do a series of pathological damages to the upper airway as it reaches the upper respiratory tract. Based on relative domestic and foreign literature, this paper attempts to make a review about the relationship between gastroesophageal reflux and adenoid hypertrophy.

Because the biology characteristic of HIV is extremely different from that of other microorganisms, HIV vaccine research has being faced with unprecedented difficulties and challenges. In the last 20 years, HIV vaccine research has been carried out mainly with two strategies, i.e., neutralizing antibody based and cellular immunization based; however, substantive breakthroughs haven't been achieved until now. Inducing effective neutralizing antibody is always an important strategy in traditional vaccine research, but this strategy is much less efficient in HIV vaccine research because of high variation and much subtypes of HIV. In recent years, the discovery of broadly neutralizing monoclonal antibodies and elucidation of their corresponding antigen epitopes have brought new hopes for the development of neutralizing antibody based HIV vaccine. Reviewing these advancements will be helpful for reconsidering HIV vaccine development with a better strategy.

Objective To investigate the effect of formoononetin on endostatin ( ES ) , vascular endothelial growth factor ( VEGF ) , matrix metalloproteinases 2(MMP-2), basic fibroblast growth factor (bFGF) in hydrothorax and serum, and tumor biomarkers of patients with elderly advanced lung cancer.Methods 67 cases elder with advanced lung cancer were selected and randomly divided into two groups.33 cases in control group were treated with conventional therapy of NP chemotherapy regimen, 34 cases in experiment group were combined with formononetin.The changes of ES, VEGF, MMP-2, bFGF, tumor marker levels in hydrothorax and serum and life quality evaluation were compared.ResuIts Compared with control group, the contents of ES, VEGF, MMP-2, bFGF in hydrothorax and serum of experiment group significantly decreased (P<0.05); the carcino embryonie antigen (CEA), neuron specific enolase (NSE), cytokeratin-19-fragments (CYFRA21-1), and carbohydrate antigen 125 (CA125) in serum of experiment group significantly decreased ( P<0.05 ); the life quality evaluation improved better of experiment group (χ2 =4.96, P<0.05 ). ConcIusion Formononetin has better clinical effect in treatment of elderly patients with advanced lung cancer patients.It could effectively improve the quality of life, reduce ES, VEGF, MMP-2, bFGF and other indicators in hydrothorax and serum, which has the vital significance to the clinical therapy.

Drug-induced nephrotoxicity is very common in both new drug development and clinic practice. Various drugs can induce kidney injuries, including tubulointerstitial, glomerular and renal vascular disease. To investigate the mechanism of drug induced nephrotoxicity is important for risk reduction of new drug development, reasonable drug usage, early discovery and effective prevention/treatment of adverse effects in clinics.

The effect of OQP, a pormula of traditional Chinese medieine belonging to the category "Precription of the Reinforeing Qi and Enriching Blood for keep the Original Qi", on cell strain of human hepatic carcinoma SMMC-7721 was observed. The results showed that OQP depressed the incorporation of both ~3H-TdR and ~(14)C-UR in cells of hepatic carcinoma. This indicated that OQP inhibited the synthesis of DNA and RNA, and the growth of the cancer cell. Such effect may result from the low ratio Cu/Zn and the high content of Se in OQP. In conclusion, in this study it has been demonstrated that OQP can not only improve the general condition of patients in advanced liver cancer and lcukopenia of patients in chemotherapy and radiotherapy, but also can inhibite the growth of the cell of hepatic carcinoma directly.

Objective To compare the effectiveness of running training, swimming training and intensified cyclic training by means of morphometry and to determine the most effective training mode to develop the aerobic ability of the skeletal muscle. study the adaptability of rat skeletal muscle to different endurance training modes. Methods Twenty-five healthy male Wistar rats of 8 weeks old were divided into five groups, 10 of them having no exercise be divided into control group 1 and control group 2, others took part in running exercise, swimming exercise and intensified cyclic exercise respectively. The rats in control group1 were killed at the beginning of the exercise. The free activity group was taken as the control group 2, the rats were not given any interventions, they could move freely in the cage and be killed at the end of the exercise (n=5). The rats in running group were forced to take part in an upward-slope (+5?) running task of medium load, the rats should kept running at the speed of 16m per minute for 45 minutes. The rats in swimming group were forced to keep swimming in the pool for 45 minutes, The rats in intensified cyclic group were kept running for 30 minutes (the running mode was same to the running group), then had a rest for 15 minutes, and at last the rats were forced to keep swimming in the pool for 30 minutes. The rats in training groups were trained for 6 days every week with 1-day rest for 8 continuous weeks. We observed the change of aerobic ability of the soles muscle in different training modes. Results The three kinds of endurance training developed the aerobic metabolism ability of skeletal muscle in rats effectively. The intensified cyclic training can do better than swimming training and running training in promoting remodeling reconstruction of skeletal muscle, and developing the muscle, function. Conclusion The intensified cyclic training can shorten the period of remodeling reconstruction of skeletal muscle, and more effective in developing the aerobic ability of the skeletal muscle than other endurance training modes.
