Interleukin-15 is a multffunctional cytokine,which are the activating and induction factors of the T-cell,B-cell,NK-cell and lymphokine-activated killer cell (LAK).It can stimulate hematopoietic stem cell proliferation and differentiation,enhance immunity and has anti-tumor effects.IL-15 and IL-2 have similar structures and functions,but many activating effects of IL-15 are stronger than the other's.IL-15 is closely related to tumor development,and has broad application prospects in biological therapy of cancer.

Objective: To assess the clinical application of transabdominal ultrasonography for the diagnosis of achalasia. Methods: The subjects were divided into 3 groups, with 8 patients suffered from achalasia as patient group, 10 normal individuals and 8 patients with cardiac carcinoma as controls. All subjects received water provocative test to study the lower esophagus and cardia. Sonographic findings were compared between the 3 groups. After treatment by administration of drugs, pneumatic balloon dilation, or intrasphincteric injection of botulinum toxin, the 8 patients were re-examined by TAUS for longitudinal comparison. Results: (1)The normal subjects had no dilation of cardia and lower esophagus before drinking water, but their cardias opened rapidly with the drinking action. (2)All the patients of achalasia were found to have dilation of lower esophagus before taking water. During 10 min continuous TAUS scanning, 5 of 8 demonstrated absence of relaxation of cardias and absence of water from the esophagus into the stomach. The other 3 showed slight and intermittent relaxation of cardias with water flow into the stomach. Thirty minutes after water provocative test, all the 8 patients had water retardation within the lower esophagus. (3)The patients of cardiac carcinoma had an ultrasound feature of cardiac ring enlargement and thickening of cardiac wall without dilation of lower esophagus before water provocative test. Water passed the cardia more slowly. Conclusion: TAUS is a readily accepted examination. It can quickly give reliable diagnostic clues to achalasia. TAUS can also be used for making assessment of therapeutic effect on achalasia.

Cerebralvasospasmisthemostcommonandmostdangerouscomplicationofsubarachnoid hemorrhage (SAH). If it can not be diagnosed and treated early, it w il result in delayed cerebral ischemia and delayed ischemic neurological deficits, and seriously affect the outcomes of patients. SAH can cause oxidative stress and inflammation, causing vasospasm, and leading to brain tissue damage. Numerous studies have show n that the concentrations and activities of numerous metabolites w il change in these pathological physiological processes. Identification of the changes of location, time and trend of these markers has important clinical significance for investigating the mechanism of cerebral vasospasm after SAH and seeking better therapeutic targets. This article review s the molecular markers of cerebral vasospasm after SAH.

Objective:To construct Cyanovirin-N(CV-N) expression plasmid pET-CVN and express the protein in E.coli, and to prepare specific antibody against Cyanovirin-N.Methods:In this study, the encoding sequence of Cyanovirin-N was obtained by PCR. The expression plasmid pET-CVN was constructed by inserting the encoding sequence of CV-N into pET-His containing T7 promoter and then BL21(DE3)strain was transformed. Expression of CV-N was induced by IPTG at 30℃ for 8 h. Cyanovirin-N was refolded by using dialysis method. The target protein was purified through Ni2+-NTA Agarose Fast Flow. The purified Cyanovirin-N was used as an antigen to immunize rats,and the polycolonal antibody to Cyanovirin-N was obtained.Results:Cyanovirin-N was cloned and expressed in E.coli successfully. SDS-PAGE analysis showed that the Cyanovirin-N was expressed in the form of insoluble inclusion body,and the expression amount of Cyanovirin-N was about 42.08% of total protein. With ELISA detection the titer of antibody was more than 1∶8 000, Western blot analysis showed that the antibody can bind with Cyanovirin-N specifically.Conclusion:Cyanovirin-N expression plasmid pET-CVN has been constructed, Cyanovirin-N with bioactivity has been obtained. The prepared antibody against Cyanovirin-N has well specificity and reactivity and can be used to detect the expression products by recombinant strains of E.coli.The work lays a foundation further study of its functions.

Objective To explore the effect of water analgesia on the pain relief for primiparas in labor, especially on the point of the acutest pain and total time of severe pains by tracking and comparing with remifentanil patient- controlled intravenous analgesia and the conventional vaginal delivery. Methods A total of 139 singleton and full-term primiparas who chosed analgesia labor were selected. There were 3 groups:56 cases in water analgesia group (hereinafter referred to shortly as water group), 37 cases in remifentanil patient-controlled intravenous analgesia group (hereinafter referred to shortly as vein group ) and 46 cases in traditional vaginal delivery group (hereinafter referred to shortly as traditional group). In addition, labor pain intensity was assessed with numerical rating scale (NRS). All groups were evaluated by NRS score in five different time points during the delivery:cervical dilation to 2-3 cm or 1 minute before labor analgesia; labor analgesia after 10 minutes; labor analgesia after 30 minutes; labor analgesia after 60 minutes;point of acutest pain. Meanwhile, total time of acutest pain, progress of labor, use of oxytocin, mode of delivery, postpartum hemorrhage and neonatal asphyxia were all observed. Results Comparison of labor progress and postpartum bleeding, mode of delivery and neonatal Apgar score in three groups of primipara showed no significant difference (P>0.05). Compared with the traditional group, the NRS score and point of acutest pain in water group obviously declined, the total time of severe pain shortened 36.58 min on average, which showed significant difference (t=-4.400, P<0.05). Compared with the vein group, the NRS score of water group at 10 minutes after labor analgesia was below the vein group (t=-2.358, P<0.05), so was point of acutest pain (t=-2.703, P<0.05). But the score of water group was higher than intravenous analgesia after 60 minutes, which showed significant difference (t=2.833, P<0.01). The rate of oxytocin application in water group was only 12.5%(7/56), significantly less than the rate in vein group, which was 37.84%(14/37), there were significant differences (χ2=8.182, P<0.05). Conclusions Water analgesia can effectively alleviate maternal pain and reduce intrapartum intervention, and more, less influence on maternal and newborn, and is a safe and effective analgesia method.
