Objective To explore the influencing factors of recurrence and metastasis of gastric cancer after radical operation.Methods The recurrence and metastasis status of 50 patients with gastric cancer underwent the radical gastrectomy were retrospectively analyzed.Logistic multiple regression was used for univariate regression analysis or multivariate regression analysis.Results The average time of recurrence was 18.4 months in 50 cases with gastric cancer after radical operation; The rate of recurrence was 14 cases (28.0%)、12 cases (24.0% )、15 cases (30.0% )、6 cases (12.0% )、3 cases (6.0% ) within six months ,0.5-1 year、1～2 years、2～3 years >more than 3 years respectively; The early recurrence in 41 cases (82.0% ) were significantly higher than the late recurrence of 9 cases (18.0%) (X2 = 6.45,P <0.01) ;The univariate regression analysis indicated that original tumor site.,tumor size,TNM stage、 degree of differentiation,Bomnann classification were influencing factors of recurrence and metastasis (P <0.01); Logistic regression multivariate analysis showed tumor size、pathological TNM staging and adjuvant chemotherapy in gastric cancer were the independent influencing factors (P<0.01).Conclusion Most recurrences would happen within 2 years after radical resection for gastric carcinoma;The tumor size、 tunior pathological stages and adjuvant chemotherapy extent were independent correlation factors of locally recurrent gastric carcinoma.

Objective By using immunohistochemical staining of neuropeptide Y (NPY) and fluorescence of ethylaldehyde acid-induced biomonoamine mediators, to observe the distribution of sympathetic nerve terminals in human cervical capsule tissues, and to compare the two methods for further improvement. Methods Surgically removed joint capsule tissues from C 3~7 vertebrae of 17 cases were treated by paraffin imbedding with NPY immunohistochemical staining and frozen-section with fluorescence staining of ethylaldehyde acid-induced biomonoamine mediators. Slides were preconditioned by 1% KMnO4 and sections 15~20 ?m in thickness were made. The staining was conducted at 100 ℃ for 5 min firstly, and then at 80 ℃ for 2 min. We utilized adrenal glands of rats as positive control. The samples were observed under fluorescence microscope at 380~420 nm excitation wavelengths from a high-voltage mercury light source. Results NPY immunostaining findings indicated bulky positive materials in some arteriolar walls and nerve tracts of the joint capsules; biomonoamine mediators gave off fluorescence in green-yellow color under the induction of ethylaldehyde acid, which presented mostly as reticular or radial finely-broken fibers in vascular walls, basal laminae of the synovial membrane and dense connective tissues. The positive rates of NPY immunohistochemical staining were 70.6% (12/17) at C 3~4 intervertebral segment, 42.9% (6/14) at C 4~5 , 57.1% (8/14) at C 5~6 , and 50.0% (5/10) at C 6~7 , respectively, the total positive rate being 56.4% (31/55). When using the ethylaldehyde acid-induced biomonoamine fluorescence, the positive rates were 70.6% (12/17) at C 3~4 intervertebral segment, 93.8% (15/16) at C 4~5 , 66.7% (10/15) at C 5~6 , and 80.0% (8/10) at C 6~7 , respectively, the total positive rate being 77.6% (45/58). The positive rate was remarkably higher in ethylaldehyde acid-induced biomonoamine fluorescence than in NPY immunohistochemical staining, with statistically significant difference (?2=5.774,P=0016), especially at C 4~5 intervertebral segment (P=0.004). Conclusions Both the two methods can demonstrate the distribution of sympathetic nerve terminals, suggesting the presence of the terminals in human cervical capsule tissues. Modified ethylaldehyde acid-induced biomonoamine fluorescence offers a greater specificity.

Objective To investigate the relationship between the expression of urokinase-type plasminogen activator (uPA) mRNA and breast cancer, lymph node metastasis. Methods Sixty patients with breast tumor were selected randomly and the expression of uPA mRNA was detected with RT-PCR. The patients were divided into benign group (18 cases) and malignant group (42 cases) which included 22 cases with lymph node metastasis and 20 cases without lymph node metastasis. The relationship between uPA mRNA expression and breast cancer, lymph node metastasis was analyzed. Results Among these 18 benign tumors, low expression of uPA mRNA was found in 2 cases and the others were negative. While in 42 cases of malignant tumor, uPA mRNA were positive in 22 cases of lymph node metastasis, 16 of which were high expression, 5 of which were moderate expression, and 1 was low expression. uPA mRNA were positive in 18 of 20 cases of nonmetastatic lymph node, 1 of which was high expression, 5 of which were moderate expression and 12 of which were low expression, the other 2 were negative expression. The expression of uPA mRNA had significant difference between benign and malignant tumors ( P

Objective To explore the effect of intervention on depression and negative coping in elderly patients with chronic disease and provide a basis for mental health services. Methods Forty depression and negative coping of elderly patients with chronic disease were took psychological intervention for one year. Geriatric depression scale (GDS) and ways of coping scale (WCS) were used to assess the intervention effect.

BACKGROUND:Hepatic vascular exclusion is important for liver transplantation that can reduce blood loss and make for liver recovery. A variety of favorable hepatic vascular exclusion techniques occur in the development of liver surgery technology, which is stil a research hot in surgical study. OBJECTIVE:To introduce the latest research and the hot spot of hepatic vascular exclusion techniques. METHODS:A computer-based online search of PubMed and Wanfang databases for articles relevant to Pringle maneuve, total hepatic vascular exclusion, selective hepatic vascular exclusion and sectional vascular exclusion under hepatectomy published from January 1999 to January 2014. Totaly 50 articles were included in result analysis. RESULTS AND CONCLUSION:There are a variety of hepatic vascular exclusion technologies, and intermittent hepatic vascular occlusion and semihepatic vascular exclusion are used most commonly. The applicable principles are as folows: (1) Surgery without vascular exclusion is suitable for < 5 cm lesions at the liver edge. (2) Semi-hepatic vascular exclusion is fit for semi-hepatic lesions, especialy for patients accompanied by liver cirrhosis. Hepatic vascular exclusion with preservation of semi-hepatic artery and liver hanging maneuver are also reported to have a certain value in clinical practice stil need further studies. (3) Intermittent hepatic vascular exclusion is suitable for lesions over half a liver or spanning liver halves (huge lesions). (4) Total hepatic vascular exclusion and its modified technologies are suitable for lesions involving the inferior vena cava and (or) hepatic vein, or lesions closely related to the second and third porta hepatis. (5) Segmental hepatic vascular exclusion is considered for smaler lesions confined to the liver segment under alowed conditions, but semi-hepatic vascular exclusion and Pringle maneuver can be also considered. Depending on patient’s conditions, to select the appropriate method is the key to reduce bleeding and to ensure patient safety.

Objective To determine the contents of fluoride and tea polyphenols in brick-tea and to understand the utilization ratio of qualified brick-tea in fluorosis regions in Inner Mongolia.Methods The investigation was carried out in Chenbaerhuqi Country and Eweukeqi Country.Seventy-two households of four villages in Chenbaerhuqi and 11 households of three villages in Ewenkeqi were selected as study subjects.The brick-tea in each household was sampled.The contents of fluoride and tea polyphenols were determined by using fluoride selective electrode method and Forint-Ciocalteu oxidation method,respectively.T test and linear correlation were used to analyze the data.Results The fluoride content in qualified brick tea ranged from 114.82 mg/kg to 290.23 mg/kg with an average value of 171.78 mg/kg,while tea polyphenols content was between 56.15 g/kg and 132.18 g/kg with an average value of 95.44 g/kg.In unqualified brick-tea,the average fluoride content was 459.86 mg/kg with the range from 304.71 mg/kg to 660.76 mg/kg and the average of tea polyphenols was 67.48 g/kg with the range from 36.03 g/kg to 102.15 g/kg.The content of tea polyphenols of qualified brick tea was significantly higher than that of unqualified brick tea (P ＜ 0.05).The content of tea polyphenols was negatively correlated with fluoride content(r =-0.636,P ＜ 0.05).The content of tea polyphenols was 396 times more than that of fluoride in brick tea.The utilization ratio of qualified brick-tea in the investigation areas was 53.0％(44/83).Conclusion The fluoride content in qualified brick-tea was less than unqualified brick-tea,and the tea polyphenols of qualified brick-tea was higher than the unqualified brick-tea.The utilization rate of qualified brick tea is not high and further actions are needed to be taken to supply more qualified brick-tea for controlling of drinking brick-tea type fluorosis.

Objective To evaluate the safety and comfort of postoperative patients with hepatocellular carcinoma after interventional therapy in the early stage and late stage, so as to determine the time to get out of bed after operation. Methods We searched PubMed, EMbase, Cochrane Library (2016 second), Web of Science, CBM, Wanfang Data and CNKI database, collect test/ambulation time of hepatocellular carcinoma after interventional therapy were searched from inception to September 10, 2016. Meta analysis was performed by 2 reviewers independently by screening literature, extracting data and evaluating the risk of bias in the study. RevMan 5.0 software was used to analyze the data. Results A total of 9 studies were included in the study, and 1164 patients were included. The Meta analysis results showed that:compared with 24 hours in bed after operation, 12 hours early ambulation method to reduce postoperative pain, postoperative [odds radio (OR)=0.07, 95% confidence interval (CI) 0.03-0.15, P <0.05] and dysuria (OR =0.18, 95% CI 0.10-0.33, P < 0.05), abdominal distension (OR =0.14, 95% CI 0.07-0.29, P<0.05), insomnia (OR=0.15, 95% CI 0.05-0.43, P<0.05). But in the local punctura, such as congestion (OR=0.99, 95%CI 0.45-2.18, P=0.98), hematoma (OR=0.90, 95% CI 0.38-2.13, P=0.80), the difference was not statistically significant. Conclusions The available evidence indicates that the early postoperative 12 hours after interventional therapy can effectively reduce the incidence of postoperative complications. To be included in the quantity and quality of the research, the conclusion still need to carry out more high-quality research to be verified.

Objective To investigate the effect and mechanism of Clara cell secretory protein (CC16 ) on lung injury of traumatic shock rats.Methods Thirty SD male rats were randomly assigned to three groups:sham-operation group,control group and CC16-treatment group.The rat model of traumatic shock was used in this study.Rats of sham-operation group were operated,but not treated by depletion and recovery.Rats of control group inhaled the physiological saline before fluid resuscitation.Rats of CC16-treatment group inhaled 0.1 μg/mL of recombinant human Clara cell secretory protein (rh-CCSP)before fluid resuscitation.Arterial blood gas analysis and wet/dry weight were detected in each group.The contents of malondialdehyde (MDA),myeloperoxidase (MPO)of lung tissues and lung tissue pathology changes were also studied. Results Compared with control group,pH and PaO2 value in CC16-treatment group increased significantly.Meanwhile,BE value and lung wet/dry weight ratio also decreased significantly (P<0.05).Compared with control group,contents of MDA and MPO in CC16-treatment group decreased significantly (P<0.05).Lung tissue pathology improved in the CC16 group compared with that of control group (P <0.05 ).Conclusion Inhaled Rh-CCSP may have potential protective effect on lung injury tissues of traumatic shock rats model through its antioxidative effect.
