Cysteine protease inhibitor SN (Cystatin SN) is a secretory protein encoded by CST1,with the promotion of cell senescence and apoptosis activity,playing an important role in the regulation of proteolytic activity.Many studies have found that Cystatin SN is abnormally expressed in various kinds of tumors,and is closely related with the tumorigenesis and progression.Cystatin SN may play an important role in the diagnosis and prognosis of tumors.

With the development of cardiothoracic surgery, anesthesia, myocardial protection and in vitro technique, the management of congenital heart disease has gradually become younger and lower, and the nursing management of the postoperative system plays an important role. The purpose of this study was to analyze the causes of malnutrition in children with congenital heart disease<6 kg, the significance of postoperative enteral nutrition support, nutritional assessment, oral feeding and tube feeding. Postoperative enteral nutrition support in children with congenital heart disease provides the most appropriate and accurate care, reduce the incidence of complications, optimize their quality of life and postoperative outcome.

OBJECTIVE To study the influence of various packing methods and controlling method toward the hidden wet pack after steam sterilization to ensure the sterilization quality and hygiene safety.METHODS The medical equipment was packed with three types of methods,then unloaded from the steam autoclave after being cooled at different time to observe their heating speed respectively.To choose two types of cotton fabric packaging methods,prolong the heating time,and cool in the steam autoclave for 30 minutes,then observe the heating speed of the inside pack and the dry qualification status after 12 hours respectively.RESULTS The heating speed was the fastest with the medical crinkly paper method;the heating speed of the inside pack didn't have any improvement after prolonging the heating time;the dry qualification rate had distinct difference between the two types of cotton fabric methods after 12 hours(P

Liver metastasis is the advanced stage of gastric cancer,which is a leading cause of death.Radiofrequency ablation (RFA) is an alternative method of comprehensive treatment in patients with gastric cancer liver metastasis due to its advantages of safety,minimal invasion and repetition.The efficacy of RFA alone,the efficacy of the combined treatment of RFA with other therapies and prognostic factors of RFA in gastric cancer liver metastasis were reviewed in this article.

Objective To evaluate the curative effect of laparoscopic myomectomy combined with preoperative gonadotropin releasing hormone agonists (GnRH-a) in treating myoma patients with uterus volume large than 12 weeks of pregnancy size. Methods 46 patients with uterine volume over 12 gestational weeks from August 2009 to August 2016 were selected as research objects. Leuprolide was injected subcutaneously for three to six times, and then laparoscopic myomectomy was performed one month later. The changes of volumes in uterus and myoma before and after medication were observed as well as the changes of hemoglobin. And postoperative recurrence of uterus myoma was followed up. Results The average volume of the uterus in the 46 patients, detected by B ultrasound, before GnRH-a treatment was (705.47 ± 282.37) cm3, and the average volume of the uterus after GnRH-a treatment was (331.95 ± 84.53) cm3, which was shortened by 59.35%, with significant difference (P < 0.05). The volume of uterus myoma was (237.59 ± 138.46) cm3 before GnRH-a treatment and (81.59 ± 46.44) cm3 after GnRH-a treatment, shortened by 65.66%, with significant difference (P < 0.05). The hemoglobin value was (97.80 ± 20.19) g/L before GnRH-a and (119.63 ± 12.06) g/L after GnRH-a treatment, with significant difference (P < 0.05). Follow-up for 3 weeks to 5 years, the surgeries were accomplished successfully, and no case was transferred to laparotomy. Conclusion Preoperative GnRH-a could shorten volume of uterus myoma, increase hemoglobin value and ensure performance of laparoscopic myomectomy for myoma patients with uterus volume large than 12 weeks of pregnancy size.

Microwave ablation(MWA) is a significant progress in tumor non-surgical treatment in the 1990s.It is characterized by high thermal efficiency,fast heating rate,high uniform temperature field,complete necrosis of coagulation area and small influencing factors.The local treatment of the tumor shows a great advantage.In recent years,with the maturity of MWA technology,it has been widely used in the treatment of liver tumors(hapatic tumor,HT),has achieved good clinical efficacy.The aim of this study is to review the progress of treatment of HT in MWA to improve its therapeutic efficiency.

Objective To investigate the comparability of K + ,Na+ and Cl- measurement between Cobas8000 analyzer and AU640 analyzer .Methods According to the EP9‐A2 document of the National Committee for Clinical Laboratory Standards ,the precision of AU640 analyzer for the detection of K + ,Na+ and Cl- was evaluated ,and the correlation between the detected results of the two analyzers were also analyzed .Results AU640 analyzer were with high precision for the detection of K + ,Na+ and Cl- ,in‐tra‐assay and inter‐assay coefficient of variation of which were both less than 2% .The correlation coefficients of the two analyzers were higher than 0 .975 .Conclusion Cobas8000 analyzer and AU640 analyzer might be with fine comparability for the detection of K+ 、Na+ and Cl- ,both of which could provide accurate detected results .

To study the effect of exercise on gene expression of natriuretic peptide receptors (NPRs) in the heart, using immunofluorescent method, in situ hybridization, laser confocal scanning microscopy and the technique of computer image analysis, the distribution of NPRs in the heart and the alterations of gene expression of NPRs on the animal model of different training intensity were investigated. The result showed that NPRs located mainly in the endocardium, the sarcolemma of myocardial fiber, the connective tissue around myocardial fiber and the wall of coronary artery branch. After moderate and heavy exercise training, the gene expression of natriuretic peptide receptor-A (NPR-A) upregulated and natriuretic peptide clearance receptor (NPR-C) downregulated, whereas the gene expression of NPR-A downregulated and NPR-C upregulated after exhaustive exercise.

To summarize the etiological factor and to assess the therapeutic effect for neovascular glaucoma(NVG).Methods A retrospective study of 28 cases (29 eyes) with NVG was performed. The mean age, proportion of sex and primary ocular disease, incidence of symptom, sign and postoperative complication were analyzed. Results 78 6% of the patients were over 40 years old. 62% of the patients were secondary to the ocular ischemic disease such as central retina vein occlusion and proliferative diabetic retinopathy. The clinical characters included intraocular pressure (IOP) increasing, pain, mixed conjunctival congestion and rubeosis iridis. The mean IOP reduction was 19.5 mmHg in 29 eyes after antiglaucomatous drags treatment and 19.13mmHg in 23 eyes after Hunan aqueous humor drainage (HAD) implantation. The common postoperative complications were flat anterior chamber and choroidal detachment. The success rate of HAD implantation was 87%.Conclusions NVG was commonly secondary to ocular ischemic disease. Although prevention was the principal, reducing IOP and ameliorating ischemic situation were as the same important.

Objective To investigate the status of stroke patients′continuous rehabilitation care and it′s influencing factors in the community. Methods Questionnaires were used to investigate 174 stroke patients from 6 communities of Zhengzhou. Results The implementation of continuous care was not satisfactory. Occupation, medical payment method and medical resource utilization were important predicting factors. Conclusions In order to promote continuous rehabilitation care, the health resources should be fully used, the payment methods of the patients should be improved, and the occupational characteristics should be considered.
