Ubiquitin specific peptidases play important roles in controlling proteasome activity,organogenesis,tumorigenesis and transcriptional regulation.Ubiquitin specific peptidase 9X is able to remove ubiquitin from substrate proteins,so it may effectively regulate the proliferation,adhesion and signal transduction of tumor cells.It is a one of the most important factors in tumor progression.

Objective To study the mechanism of Chinese Medicine in treating adenomyosis. Methods Thirty-seven patients in the Chinese Medicine treated group (17 cases of adenomyosis) and the control group (20 cases of adenomyosis, non-drug treated) underwent hysterectomy. Endometrium was looked as eutopic endometrium and adenomyosis as ectopic endometrium. Expression of MMP-9 and TIMP-1 in eutopic and ectopic endometrium were measured by immunohistochemical techniques. Meanwhile the levels of CA125 in serum were measured. Results The ectopic endometrium of the Chinese Medicine treated group expressed lower level of MMP-9, higher level of TIMP-1 and lower ratio of MMP-9/TIMP-1 than the ectopic endometrium of the control group (P<0.05). The levels of CA125 in serum were significantly decreased in Chinese Medicine group after treated as contrast with those in control group. Conclusion Chinese Medicine could reduce the level of CA125 and the ratio of MMP-9 and TIMP-1 to prevent the progression of adenomyosis.

Objective To explored the mental stress situations and the relationship between mental stress, coping style and self-efficacy beliefs of the highland training recruits, and suggestions about mental health education of the recruits to be proposed.Methods The solider mental stress self-reported questionnaire, simplied coping style questionnaire, and generalized self-efficacy beliefs scale were administrated to 256 recruits from 3 companies have been randomly selected in a military training base of Qinghai province.Results The mental stress of the recruits included tension, sleepless, physical and mental exhaustion.The mental stress was significant positive correlation with negative coping style( r=0.349, P＜0.01 ), and significant negative correlation with active coping style( r= -0.179, P＜0.01 ), and with self-efficacy beliefs( r= -0.210, P＜0.01 ).Meantime selfefficacy beliefs was significant positive correlation with active coping style( r = 0.532, P ＜ 0.01 ).Negative coping style and self-efficacy beliefs could significantly predict mental stress.Conclusion Through these ways which improving the self-efficacy beliefs and instructing them to use suitable coping style may help the recruits reduce the mental stress.

Objective To investigate the influences of age and sex on the expression of serum antinuclear antibody (ANA) and its titer level.Methods The serum ANA in 993 people aged 60 years and over were detected and titer of positive serum were analyzed. They were divided into different groups according to age and sex. Two hundred healthy cases aged less than 60 years were collected as control group. Results The serum ANA positive rate was increased with age and it was significantly higher in people aged 60 years and over than aged less than 60 years (29. 1% vs. 14.0%, x2=5. 074, P=0. 025). The serum ANA positive rates were 24.1%, 30. 5% and 33.6% in people aged 60-69 group, aged 70-79 group and aged above 80 group. Among people aged 60 years and over, the positive rate was 35.8% in female group, which was higher than in male group (22. 4%) (x2= 21. 179, P=0. 05). The titre levels of the positive samples were increased with age. In control group, the samples with 1 : 100 titre was 57.1% among the positive samples, which was higher than in the elderly group (36. 3%). And in control group, the samples with 1 : 3200 titre was 0 among the positive samples, which was lower than in the elderly people group (7.6%). The ANA preliminary screening in people aged 60 years and over showed that the titre level was less than 1 : 320-1: 1000 in female and less than 1 : 100-1: 320 in male. Its specificity could be up to about 90%. Conclusions The serum ANA positive rate in people aged 60 years and over is affected by age and sex. The positive rate is higher in female than in male and it is increased with age. It suggests that 1 : 320 to 1 : 1000 could be taken as ANA preliminary screening critical value in female and 1 : 100 to 1 : 320 in male.

Hepatocellular carcinoma (HCC) with a diameter > 5 cm is defined as large HCC. Hepatic resection is the first choice for solitary large HCC with intact capsule and without satellite nodules. The key to successful large HCC resection is to judge the resectability and estimate the remnant liver function preoperatively. Moreover, the liver must be exposed and dissociated adequately, and familiarity with the anatomy of the liver is crucial. Choosing the right technique of hepatic blood flow occlusion and avoiding excessive resection of the liver are important elements. Special attention should be paid to the efficacy of liver transplantation for patients with large HCC exceeding Milan criteria, h is advisable to resect large HCC actively.The hepatic resection is safe and feasible in selected patients with large HCC.

regulatory T cell(Treg)is a subset of immunosuppressive Th cell lines with ability to sup-press anti-tumor immunity. Tregs are recruited into local tumor microenvironment by tumor-released chemokine CCL22. Tregs induce Th2-type immune responses which contribute the host ignorance and tolerance to tumor cells via releasing of immunosuppressive cytokines and immunosuppressive receptors. Accumulating evidences indicate that inhibiting Treg can break immune tolerance,and subsequently inhibit the growth and progress of cancer. These discoveries and exploration of Treg provide us a new therapeutic target and strategy with promising clinic application.

Objective To investigate the clinical effect ofFuzheng-Shugan decoction on the treatment of patients with the treatment nodule.Methods A total of 80 patients with thyroid nodule from Jan.2014 to Dec.2015, divided into two groups. The efficacy, thyroid stimulating hormone, high risk factors, the maximum diameter and volume of thyroid nodules were observed.Results The effective rate of observation group was significantly higher than of the control group (90.00%vs.27.50%,χ2=32.237,P=0.000). The shortness of breath (1.62 ± 0.86vs. 4.35 ± 1.13,t=12.159), foreign body sensation (2.53 ± 0.62vs. 4.23 ± 0.56,t=12.289), irritability (1.56 ± 0.53vs. 3.52 ± 1.25,t=9.130), sweating (1.85 ± 0.62vs.4.23 ± 0.56,t=18.017), tongue (1.58 ± 0.93vs. 3.71 ± 1.25,t=8.646) and neck pain (0.82 ± 0.35vs. 3.92 ± 0.65,t=26.558) in the obversation group were significantly lower than those in the control group (P<0.05). The thyroid stimulating hormone levels in the observation group (1.05 ± 0.21 mIU/Lvs. 2.16 ± 0.71 mIU/L,t=9.482), were significantly lower (P<0.05). The maximum diameter (8.52 ± 4.72 mmvs. 12.27 ± 5.69 mm,t=3.208) nodule volume (0.26 ± 0.71 cm3vs. 0.96 ± 1.02 cm3,t=3.562) and high risk factors (2.73 ± 1.45vs. 4.05 ± 1.36,t=4.199) in the observation group were significantly lower than those in the control group (P<0.05).Conclusion TheFuzheng-Shugan decoction can improve TCM syndrome, reduce the risk factors, and effectively reduce the nodule maximum diameter and volume.

The application of transesophageal echocardiography (TEE) in perioperative monitoring was introduced,and its involvement in non-cardiac surgery was described.The advantages and disadvantages of TEE were analyzed when applied to cardiac and non-cardiac operations for congenital heart disease,coronary disease,vascular heart disease,aorta disease and etc.The abuse of vasoactive drug or fluid is avoided due to subjective evaluation on cardiac function and volume load.TEE facilitates the anesthetist in diagnosis and evaluation of the patient with heart diseases,and the surgeon in immediate assessment of the operation,which can be used for real-time monitoring of cardiac function and hemodynamics.
