Objective To compare and analyze the biochemical detection results of separated se- ra with the separation gel coagulation promoting tubes and the drying tubes. Methods Venous blood samples was collected from identical blood donors and randomly poured into the separation gel vacuum collective tubes (test group) and traditional drying collective tubes (control group). After serum sepa- ration, timely biochemical detection was performed. The detection results were compared and ana- lyzed. The samples of test group were detected once again after storage for 24 h at 4 ℃. The results were compared with those of timely biochemical detection with separation gel separated sera. Results The results from the test group and those from the control group had no significant difference. The most results from the sera storaging for 24 h at 4 ℃ and those from the fresh serum of the test group had good correspondence. Only a few of biochemical indicators had significant difference. Conclusion The biochemical detection with sera obtained by separation gel tubes and those collected by drying tubes has good correspondence. The separation gel tubes provide the clinical laboratory optimal blood samples and more accurate results.

Objective To explore the relationship between Wuyishan cliff tea and esophageal cancer,and make integrated measures to prevent and control esophageal cancer.Methods A case-control study was conducted with a ratio of 1 to 1 and a health survey was conducted on objects which included 92 cases with histologically confirmed diagnoses of squamous-cell carcinoma of the esophagus and 92 controls matched by age,sex and resident.The analysis method of conditional logistic regression was used to analyze the influence of cliff tea on the development of esophageal cancer. Results The frequency of cliff tea drinking was 73.91% in cases with esophageal cancer compared with 84.78% in controls. As compared with subjects without tea drinking,subjects with cliff tea drinking significantly decreased the risk for developing esophageal cancer (P<0.05),and its OR were 0.60.The risk of esophageal cancer significantly reduced with increasing frequency of cliff tea drinking per week. Furthermore, we also found that the risk of esophageal cancer significantly reduced with the duration of cliff tea drinking and the early of beginning to drink cliff tea.Conclusion Wuyishan cliff tea drinking may protect against the risk of esophageal cancer.

In order to investigate the effects of phenylalanine, tyrosine and tyramine on the growth of Lycoris radiata suspension cells and the accumulation of alkaloids, the growth quantity of the cells as well as the content of alkaloids in cells were determined, which were treated with above three kinds of precursors alone and phenylalanine combined with tyrosine respectively. The results indicate that the addition of phenylalanine alone and addition of phenylalanine on the basis of tyrosine at high concentration (200 micromol/L) had no significant effect on the growth of Lycoris radiata suspension cells and the content of alkaloids in cells; whereas tyrosine and tyramine promoted the growth of the cells and alkaloids accumulation. Treated with tyrosine at high concentration (200 micromol/L), the content of alkaloids of the cells was 2.56-fold higher than that of the control group, the amounts of lycoramine (3.77 mg/g) and galanthamine (4.46 mg/g) were 6.61-fold and 6.97-fold higher than that of the control group, respectively. When treated with tyramine (200 micromol/L), the amount of alkaloids in Lycoris radiata suspension cells was 2.63-fold higher than that of the control group, and the amounts of lycoramine (4.45 mg/g) and galanthamine (5.14 mg/g) were 9.08-fold and 9.18-fold higher than that of the control group, respectively. The above results demonstrate that adding tyrosine and tyramine in the media significantly promoted the growth of the Lycoris radiata suspension cells and alkaloids accumulation in the cells.

Objective To understand the status of pregnant women body maternal body mass management knowledge and analyze its influencing factors.Methods In 28 specialist maternity hospital,the production inspection of 631 pregnant women were investigated with self-designed maternal body mass management knowledge questionnaire.Results At present, the knowledge of the maternal body mass management of pregnant women mainly came from the network (32.3%),the lecture (26.5%)of the hospital organization,the access to the knowledge manual (26%),and other ways (19.2%);multiple stepwise regression analysis showed that pregnant women marriageable age,educational level,production time were the influential factors of body mass management (P <0.05).Conclusions The body mass management knowledge of pregnant women is poor.It is relevant with that pregnant women do not pay attention to the body mass management and they are lack of approaches to master the knowledge.So the maternity hospital at all levels should emphasis on body mass management knowledge education,establish body mass management clinics and hospital network platform for the pregnant women,in order to promote the level of body mass management knowledge of pregnant woman on the basis of assessment.

Objective:To evaluate the effect of position change and pneumoperitoneum pressure on the respiratory system of patients undergoing DaVinci assisted laparoscopic prostate cancer surgery.Methods:Peak airway pressure, lung compliance and airway resistance were recorded by ventilator as the basic values to evaluate the change of respiratory function. When the artificial pneumoperitoneum pressure was 10 mmHg or 15 mmHg, the changes of respiratory function were recorded in five different positions: trendelenburg position (head low foot height) 30°, 15°, supine position, anti-trendelenburg position (head high foot height) 15° and 30°, peak airway pressure, lung compliance, airway resistance and so on.Results:At 10 mmHg and 30° trendelenburg, peak airway pressure, lung compliance and airway resistance were 28.13 cmH 2O, 23.33 ml/cmH 2O,16.06 cmH 2O·L -1·Sec -1, respectively. When the pneumoperitoneum pressure was adjusted to 15 mmHg, peak airway pressure increased to 32.03 cmH 2O, lung compliance decreased to 20.14 ml / cmH 2O, and airway resistance increased to 117.24 cmH 2O·L -1·Sec -1( P<0.01). At 10 mmHg and trendelenburg returned to 15°, peak airway pressure, lung compliance and airway resistance were 26.66 cmH 2O, 24.95 ml/cmH 2O,15.50 cmH 2O·L -1·Sec -1, peak airway pressure increased to 30.61 cmH 2O, the lung compliance decreased to 20.89 ml/cmH 2O and airway resistance increased to 16.66 cmH 2O·L -1·Sec -1 ( t value was -43.81, 24.638, -12.812, P<0.01). Conclusion:With the increase of trendelenburg position angle and artificial pneumoperitoneum pressure, the peak airway pressure and airway resistance are increased, while the lung compliance decreases gradually. Compared with trendelenburg position, the change of artificial pneumoperitoneum pressure has more influence on respiratory function.

OBJECTIVE:To observe clinical efficacy and safety of mesalazine combined with Kangfuxin solution retention en-ema in the treatment of active ulcerative colitis(UC). METHODS:A total of 120 patients diagnosed as active UC selected from gastroenterology department of our hospital during Mar. 2012 to Aug. 2014 were divided into observation group and control group according to random number table,with 60 cases in each group. Both groups received conventional treatment of active UC. Control group was additionally given Mesalazine enteric coated tablets 1 g,tid,on the basis of routine treatment.Observation group was ad-ditionally given Kangfuxin solution 30 mL diluted with normal saline 150 mL for enema,qd,on the basis of control group. Both groups were treated for 30 d. The serum levels of TNF-α,IL-1,IL-8,IL-10,SOD,NO and LPO were observed in 2 groups be-fore and after treatment;clinical efficacies,recurrence rates,colonoscopy efficacies and the occurrence of ADR were compared be-tween 2 groups. RESULTS:Before treatment,there was no statistical significance in the serum levels of TNF-α,IL-1,IL-8, IL-10,SOD,NO or LPO between 2 groups(P>0.05).After treatment,the serum levels of TNF-α,IL-1,IL-8,NO and LPO in 2 groups were decreased significantly,while the serum levels of IL-10 and SOD were increased significantly;the serum levels of TNF-α,IL-1,IL-8,NO and LPO in observation group were significantly lower than control group,while the serum levels of IL-10 and SOD were significantly higher than control group,with statistical significance(P<0.05). Clinical response rate,recur-rence rate and colonoscopy response rate of observation group were 83.3%,11.7% and 88.3%,which were significantly better than 66.7%,30.0%,70.0%of control group,with statistical significance(P<0.05).There was no statistical significance in the in-cidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Mesalazine combined with Kangfuxin solution can effectively alle-viate inflammatory reaction in patients with active UC,and reduce oxygen free radical damage with good safety.

Objective:To investigate the effect of hybrid intensity modulated radiotherapy (Hy-IMRT) on immune function in patients with locally advanced breast cancer surgery and the treatment efficacy.Methods:A total of 94 patients with locally advanced breast cancer who underwent modified radical mastectomy for breast cancer and required postoperative radiotherapy in Changzhou Cancer Hospital in Jiangsu Province from January 2015 to January 2017 were selected. The patients were divided into Hy-IMRT group (observation group, 47 cases) and three-dimensional conformal radiotherapy (3DCRT) group (control group, 47 cases) according to the random number table method. The dose and related radiophysical parameters of the respective target areas of the two groups, adverse reactions during and after radiotherapy, cytokines and T lymphocyte subsets before and after radiotherapy, 3-year local recurrence rate, distant metastasis rate and mortality were observed and compared between the two groups.Results:The dose obtained by 95% (D 95%) [(4 945.6±36.1) Gy vs. (4 754.0±35.6) Gy] and target area conformity (CI) of the target volume (0.7±0.1 vs. 0.5±0.1) in the observation group were greater than those in the control group, and the differences were statistically significant (both P<0.05); the target volume of 110% of the prescription dose (V 110%) [(1.6±0.5) cm 3 vs. (8.4±1.2) cm 3], the target volume of more than 105% of the prescription dose (V 105%) [(19.3±3.5) cm 3 vs. (26.6±5.6) cm 3] and the heterogeneity index (HI) (1.1±0.1 vs. 1.3±0.1) in the observation group were all smaller than those of the control group, and the differences were statistically significant (all P < 0.05). The incidence of acute skin adverse reactions [53.2% (25/47) vs. 74.5% (35/47)] and the incidence of bone marrow suppression [40.4% (19/47) vs. 70.2% (33/47)] in the observation group were lower than those in the control group, and the differences were statistically significant (both P < 0.05). There were no significant differences in levels of interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α), CD4 +, CD8 +, and CD4 +/CD8 + between the two groups before radiotherapy (all P > 0.05). At the end of radiotherapy, the levels of IL-6, TNF-α and CD8 + were higher in both groups than before radiotherapy (all P < 0.05), and CD4 + and CD4 +/CD8 + were lower than before radiotherapy (both P < 0.05). The levels of IL-6, TNF-α and CD8 + in the observation group were lower than those in the control group, while the CD4 + and CD4 +/CD8 + were higher than those in the control group (all P < 0.05). The 3-year local recurrence rate [34.04% (16/47) vs. 42.55% (20/47)], distant metastasis rate [25.53% (12/47) vs. 38.30% (18/47)] and mortality rate [14.89% (7/47) vs. 19.15% (9/47)] in the observation group were lower than those in the control group, but the differences were not statistically significant (all P > 0.05). Conclusion:Compared with 3DCRT, the Hy-IMRT has less effect on the immune function of locally advanced breast cancer patients after modified radical resection, and the incidences of acute skin reaction and bone marrow adverse reaction are low.

Objective To investigate the expression of Rab11 in children with sepsis at different sta-ges and severe sepsis and its relationship with the occurrence and development of sepsis in children. Methods A prospective control study was performed. All cases were enrolled from Bao′an Maternal and Children Health Care Hospital, and they were divided into sepsis group(40 cases) who were diagnosed as sepsis, severe sepsis group(20 cases) with diagnosis of severe sepsis,and healthy control group(40 healthy chil-dren) . Venous blood samples were collected at admission,and the expression level of blood leukocyte Rab11 was determined by Western blot. In the sepsis group,the expression levels of Rab11 were evaluated at the initial,the extreme and the recovery stages of sepsis,and were compared with those in severe sepsis group and healthy control group, respectively. Spearman correlation analysis was used to evaluate the relationship between the expressions of Rab11 and the levels of some parameters in blood,including white blood cell,neu-trophils,lymphocytes,monocytes,eosinophilic granulocyte,C-reactive protein and procalcitonin in blood,at the extreme stage. Meanwhile,the levels of Rab11 at extreme stage of sepsis,caused by different diseases, such as severe pneumonia,bronchiectasis complicated pulmonary infection,biliary tract infection,urinary tract infection, necrotizing enterocolitis and severe enteric viruses infection, were compared with each other. Results At the initial and the extreme stages of sepsis, as well as in severe sepsis group,the levels of Rab11 were significantly lower than that in the healthy control group(0. 54 times,0. 23 times and 0. 07 times, P<0. 05,respectively). There were no significant differences in the expression levels of Rab11 at the recovery stages of sepsis compared with that in the healthy control group(P>0. 05). There was no relation-ship between the level of Rab11 and the number of white blood cell, neutrophils, lymphocytes, monocytes, eosinophilic granulocyte, while the level of Rab11 was negatively correlated with C-reactive protein ( r =-0. 58,P=0. 014) and procalcitonin(r= -0. 63,P=0. 003) at the extreme stage of sepsis. There was no significant difference in the expression level of Rab11,at the extreme stage of sepsis,among those patients with severe pneumonia,bronchiectasis and pulmonary infection,biliary tract infection,urinary tract infection, necrotizing enterocolitis and severe enterovirus infection(P>0. 05). Conclusion The level of Rab11 is differently expressed at different stages of sepsis,and could be used as a predictor of the severity of sepsis in children.
