Objective To evaluate the effect of transcatheter arterial chemoembolization (TACE) and delayed surgery for infant hepatoblastoma.Methods TACE was performed with the initial digital subtractive angiography (DSA) under general anesthesia 1-3 times in 8 infants with huge hepatoblastoma, whose age was 2 to 12 months. DSA was done via arterials in hepatoblastoma each time before chemoembolization. The arterials were perfused with chemodrugs and suspensions in ultrasome iodized oil , and were blocked with spring rings. DSA findings indicated that the tumor shrank without new tumorous arterials after 1 month in 6 cases, and 4 of them showed no tumorous staining, and the delayed surgery was performed successfully 1 week later in 6 infants. One boy underwent systemic chemotherapy alone during 6 months after 3 times of TACE. Results TACE therapy did not encounter any major technical problem or toxic reaction caused by chemotherapy. The following DSA test 4 weeks later did not detect any new tumorous vessels in 6 cases. Six children received TACE and surgery had been followed-up with no tumor recurrence for months averagely. The boy underwent TACE and venous chemotherapy for 6 months , without surgery , had been followed-up for 48 months until the present report. CT, AFP and DSA did not show any hints of tumor recurrence. Six cases receiving 3 times TACE combined with surgery survived without tumor recurrence. Conclusions TACE is a very effective, safe and helpful therapy for hepatoblastoma, which stressed the repeated use of spring ring to block tumor vessels lastingly if necessary. If surgery is required, DSA test is needed beforehand to detect new tumorous vessels or neoplasm. If there is any , TACE is repeated. TACE combined with surgery may provide an additional promising choice in the treatment of hepatoblastoma, and repeated TACE alone may cure hepatoblastoma in infants.

Objective To explore whether the inflammatory stress can increase insulin resistance in the CD36 knockout (KO) mice.Methods After the mice were fed a standard chow for 14 weeks,oral glucose tolerance test,insulin release tests,lipids metabolism,SAA,IL-6,TNF-? and hepatic mRNA and proteins expression of mTOR,S6K,IRS-1,pIRS-1,2 were measured.Results Compared with the wide-type,the CD36 KO mice un-inflamed exhibited insulin resistance,and the insulin resistance index was increased[(3.01?1.24) vs (0.81?0.12),P

The G protein-coupled estrogen receptor (GPER), also known as G protein-coupled receptor 30 (GPR30), was identified in the recent years as a functional membrane receptor different from the classical nuclear estrogen receptors. This receptor is widely expressed in the cortex, cerebellum, hippocampus, heart, lung, liver, skeletal muscle, and the urogenital system. It is responsible for the mediation of nongenomic effects associated with estrogen and its derivatives, participating in the physiological activities of the body. The present study reviews the molecular structure, subcellular localization, signaling pathways, distribution, and function of GPER in the male reproductive system.

Objective To investigate the effect of individual nostalgia therapy on positive feelings and sadness of the spouses of postoperative patients with esophageal cancer. Method From June 2014 to June 2015, 60 hospitalized patients and their 60 spouses were set as control group. Routine health education and guidance were conducted once or two times a week for 7 weeks. Another 60 cases of hospitalized patients and their 60 spouses during July 2015 and June 2016 were set up as observation group. The patients were treated with the same nursing intervention as in the control group, and their spouses were subjected to individual nostalgia treatment once a week for 7 weeks. Before the intervention (postoperative day 2) and 7 weeks after the intervention, the positive aspects of caregiving (PAC) and the Margit-Meuser caregiver grief ineventary short form (MM-CGI-SF) were used to investigate their positive feelings and sadness. Result The score on spouse's positive feelings in the observation group after intervention was significantly higher than those of the control group and that of the observation before intervention (P < 0.01). Conclusion Individual nostalgia can effectively improve the feelings of the spouses of esophageal cancer patients and reduce their grief.

Objective:To explore the expression of TNF a and IL-10 in different layers of laryngeal tissues after laryngeal transplantation and its relationship with acute rejection.Methods:Laryngeal heterotopic transplantation was performed in Wistar and SD rats(Wistar→SD rats).The SD rats were divided into 4 groups:GroupⅠ:Sham control(receive no transplantation): GroupⅡ(receive transplantation,without cyelosporine A treatment);GroupⅢ(receive transplantation.with 5 mg?kg~(-1)?d cyelosporine A treatment):and GroupⅣ(receive transplantation.with 10 mg?kg~(-1)?d~(-1)cyelosporine A treatment).The transplanted larynx was harvested on 3,7 and 11 days after transplantation for pathological examination.The expression of TNF-?and IL-10 in different layers of grafts was detected immunohistochemically.Results:Pathological observation showed mild,moderate and severe acute rejection in GroupⅡandⅢon 3.7 and 11 days after transplantation,respectively:there was no obvious rejection in GroupⅣ.Immunohistochemical staining showed expression of TNF-?and IL-10 in GroupⅡ.Ⅲ.andⅣ,not in GroupⅠ.The ratios of the positive areas of TNF-?and IL-10 in the mucosal and submucosal layers were significantly higher than those in the muscle and cartilage layers of laryngeal tissues(P

In this study, OVA-induced asthma mice was taken as the model, and orally administered with different concentration of ethanol extracts of crude and processed Stemona tuberosa, in order to determine the cytokine level released from Th1 and Th2 in splenocytes. RT-PCR was carried out to determine the genetic expression of T-bet/GATA-3 in lung, and compare the differentiation between ethanol extracts of crude and processed S. tuberosa in therapeutic effect on asthma in mice. According to the results, compared with the crude samples, processed samples significantly increased the levels of inflammatory factor INF-gamma (P < 0.05) and decreased IL-5 (P < 0.05) in splenocytes. According to the RT-PCR results, the administration of processed samples could increase the ratio of T-bet/GATA-3 (P < 0.05). The experiment showed that ethanol extracts of both crude and processed S. tuberosa could treat asthma by regulating Th1/Th2 ratio, but processed samples showed more notable effect. This indicated that crude and processed S. tuberosa had significant pharmacological difference. Therefore, it was more rational to apply processed S. tuberosa in clinical treatment of asthma and chronic cough, which layed a foundation for further revealing the processing mechanism of S. tuberosa.

Plant samples were collected and investigated periodically. According to the growth of different parts and the characteristics of dry substance accumulation of Scrophularia ningpoensis, the development of S. ningpoensis could be divided into four stages: seeding stage, stem and leaf growth stage, expanding period of root tubers, and dry substance accumulation stage of root tuber. Leaf numbers of S. ningpoensis grew gradually from one at first to 370 at the final stage, main stem leaf were 50 pieces. Leaf size increasesed with the fastest growth at the stem and leaf growth stage, average daily increase amount was 225 cm2. By the middle of August, leaf size reached to 16,270 cm2. Leaf area indexrose sharply in the seeding stage, and remained above 8 among stem and leaf growth stage and expanding period of root tubers, and rapidly reduced to zero in the stage of dry substance accumulation of root tuber. Leaf area ratio has a tendency of obvious dropping. The net assimilation rate had a small change ranges, two small peak were seeding stage and dry substance accumulation of root tuber. The value of specific leaf area was higher in seeding stage, and in the earlier stage of dry substance accumulation of root tuber. Relative growth rate changed with large ranges, higher in seeding stage, rapid decrease in stem and leaf growth stage, rose in expanding period of root tubers, and declined again in the stage of dry substance accumulation of root tuber. Crop growth rate was higher in the first and last stages, and smaller in interim stage. The growth parameters of S. ningpoensis such as relative growth rate, net assimilation rate, leaf area index, leaf area ratio, specific leaf area, crop growth rate changed along with the growth. The rule of dry matter accumulation was as follows: the dry matter increased slowly during the seeding stage and speeded up in the middle and late stages, and in dry substance accumulation of root tuber increased slower, the growth of dry matter all appeared an "S" curve, and accorded with logistic equation. Cultivation technologies of S. ningpoensis and the relevant management methods could be established according to the growth of different parts of S. ningpoensis and the characteristics of dry substance accumulation in different stage.

Background and purpose: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a new minimally invasive method in the dignosis for mediastinal lymph nodes. This study was to evaluate the diagnostic yield of EBUS-TBNA for mediastinal lymph nodes. Methods: Twenty patients with mediastinal lymph nodes found by CT underwent the dignosis by EBUS-TBNA form April 1st 2009 to July 16th 2009. The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of EBUS-TBNA were evaluated. Results: Twenty patients with 37 lymph node groups were studied. Overall sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of EBUS-TBNA for diagnostic were 84.62%, 100%, 100%, 77.78% and 90.00%, respectively. The diagnostic accuracy for cancer was 100%. The operation time was 11.9min per group in average with no serious complication. The median length of hospital stay was 1 (range from 1 to 17 days) day after operation. There were significant differences in the average operation time between the first three patients and the others (36.25 min vs. 7.76 min; z=3.247, P=0.001). Conclusion: Endobronchial ultrasound-guided transbronchial needle aspiration proved to be a safe procedure with a high yield for the diagnosis of mediastinal lymph nodes.
