INTRODUCTIONCrypt epithelial cells in normal small intestineproliferate at a high speed. But they are verydifficult to culture in vitro and passage stably. A lotof studies have been done[1-16]. Some domestic labsisolated and cultured crypt cells from embryonalintestines and aseptic animal intestine, but *** introduced normal rat epithelial cell line-IEC-6from the USA and its living condition for stablepassage was successfully established after trials. Thecell line was testified to be the small intestinalepithelial cell by electron microscopy,immunihistochemistry and enzymatic histoch-emistry. It has been applied to some relatedresearch work[17-21]. It was found that manyfactors were involved in the culture system. Ourpresent study focuses on the culture method and theinfluencing factors on IEC-6.

为了确定综掘工作面压风气幕形成机理与阻尘效果,采用数值模拟与现场实测相结合的方法,分析了压风口与工作面不同距离时风流与粉尘流场运移规律,结果表明:压风气幕的形成主要由压风涡流风流场与工作面距离决定,若涡流风流场与工作面距离大于抽风口与工作面距离,可在压风口与抽风口间形成风流方向均指向工作面的压风气幕,压风口与工作面距离越大,涡流风流场与工作面距离越大,越利于形成压风气幕;数值模拟确定了50 mg/m3以上高浓度粉尘扩散距离随压风口与工作面距离变化的数学关系式;现场实测也显示,压风气幕阻尘效果明显,压风口距工作面30 m时,形成的压风气幕使距工作面10 m断面测点的粉尘浓度降至19.2 mg/m3,有效提高了除尘风机抽尘量,降低了现场粉尘浓度。

The mainly problem this thesis will solve is how to meet the time limits in functional testing of car alarm based on CAN bus. To effectively solve this problem, the bus testing system do a scheduling every 2ms with timer. Thus control of resources can be transferred to important tasks. By this method, the system completely satisfies the time limits in functional testing of car alarm. In practical, the system plays an important role in the production process, which possesses complete functions, good stability, friendly software interface, and so on.

The potential survival benefit of neoadjuvant chemotherapy(NC)in patients with advanced gastric cancer has been widely *** the development of minimally invasive surgery,which is represented by laparoscopy,the effect of NC on the safety of laparoscopic gastrectomy remains to be further *** To compare the short-term outcomes of laparoscopic total gastrectomy(LTG)after NC(NC-LTG)with LTG *** A total of 92 patients who underwent NC-LTG and 381 patients who received LTG alone at the Chinese PLA General Hospital between September 2015 and September 2020 were retrospectively included in our *** used propensityscore matching(PSM)to balance baseline *** 1:1 PSM,73 patients were included in each group with no statistically significant difference in baseline *** The NC-LTG group exhibited a longer operation time(244.10±48.13 min vs 225.74±45.33 min,P=0.019)and increased intraoperative blood loss[150(100-300)mL vs 100(100-200)mL,P=0.011]compared to the LTG *** 30-d postoperative morbidity of the NC-LTG group was 20.5%(15/73),and that of the LTG group was 13.7%(10/73).There were no significant differences in 30-d severe complication rates or anastomotic leakage *** analysis showed that the patients with pTNM(pathological tumor-node-metastasis classification)T0N0-II in the NC-LTG group underwent a longer operation than the LTG group,while no significant difference was found in any perioperative index for the pTNM III patients.A multivariate analysis showed that an operation time longer than 240 min was an independent risk factor(odds ratio=3.021,95%confidence interval:1.160-7.868,P=0.024),while NC was not an independent risk factor for postoperative complications in *** Despite a longer operation time and more blood loss after NC-LTG,which indicate surgical difficulty,NC-LTG exhibits acceptable short-term outcomes compared to LTG,suggesting the safety and feasibility of NC-LTG.

Intra-arterial chrono-chemotherapy for liver metastasis arised from colorectal cancer

中国化学会第九届全国无机化学学术会议

Hydrogen energy, an environmental-friendly alternative energy, is hopeful to replace the C-containing fuels that are still used in our life right now.1 However, searching for safe and efficient hydrogen storage approaches is still the key obstacle to its widespread use, thus numerous efforts have been made on such investigation. Over the past decades, many approaches have been developed for searching for suitable hydrogen storage materials, such as metal hydrides, sorbent materials, and chemical hydride systems.2 Among them, the liquid-phase chemical hydrogen storage materials have been considered more advantageous over traditional solid-phase hydrogen storage materials due to their merits of using existing liquid-based fuel distribution, easy handling and transportation as well as the absence of any solid byproduct. To this end, the liquid-phase hydrogen storage materials, such as formic acid（HCOOH）, liquid organic hydrogen carriers（LOHCs）, liquid amine borane complexes and hydrous hydrazine have received considerable attentions. Hydrous hydrazine（N2H4·H2O）, merits considerable attention as a potential candidate of chemical hydrogen storage material due to its high hydrogen content of 8.0 wt%, easy recharging through electrolytic process, and with nitrogen as the only byproduct via the reaction（Eq.（1））. However, in view of hydrogen storage application, the pathway of decomposition to ammonia by the reaction（Eq.（2）） should be avoided.3 Our efforts were focused on developing a number of Ni-based nanocatalysts toward the decompositions of hydrous hydrazine. To avoid the aggregation of the metal NPs, the Metal-Organic Frameworks（MIL-101） were selected as the supports due to the limited window size, pore size as well as the large surface areas. To our delight, some good results have been obtained.

Objective To evaluate the toxic effects and efficacy of the intra-arterial chrono-chemotherapy on patients with liver metastasis arised from colorectal cancer. Methods Chemotherapy of 42 patients were randomly divided into group A (n = 20) with continuously constant arterial infusion, and group B (n = 22) with arterial chrono-modulated infusion. And the toxic effects and efficacy of two groups were compared. Results A significant difference was found in the toxic effects of digestive system between the two groups. The treatment response was similar in the two groups. Conclusions Intra-arterial chrono-chemotherapy may decrease the toxic effects and improve the life quality of these patients.

研究了多输入多输出广播通信(MI MO BC)系统中的信道量化反馈问题.通过分析得到了一个接收用户容量上界,并基于该上界最大化构造了一种新的量化反馈方法.该方法采用随机量化码本,不仅考虑了信道的方向还考虑了子信道增益信息.仿真结果表明,相对只量化反馈信道方向信息的方法,该方法不仅显著提高了量化误差存在下的系统容量,并且复杂度更低.
