Objective To investigate the effects of different means of liquid resuscitation on microcirculation in rats with hemorrhagic shock. Method A model of rats with hemorrhagic shock was established in 40 Wistar rats. The rats were randomly divided into 4 groups according on different means of liquid resuscitation, and killed 24 hours after the examination, group A: without liquid resuscitation; group B: low-molecular-weight-40; group C: 7.5% hypertonic saline,group D:low-molecular-weight-40 + hyperonic saline. As well as the microcirculation in kidney was observed using electron microscope. Results In group without resuscitation, the microcirculation in kidney damaged severely; While in group with hypertonic or low molecule dextran alone, there was harm with dif-ferent degrees, and the microcirculation in kidney was nearly perfect in group with both hypertonic and low molecule dextran alone. Conclusions Different means of liquid resuscitation may infect the microcirculation in kidney, which with both hypertonic and low molecule dextran can protect the microcirculation in kidney.

Recent years found a series of severe incidents of injuring or killing medical workers in several places in China,deteriorating patient-physician relations,and disturbing medical orders.Beijing Administration of Hospitals,since its founding,has attached great importance to the management of medical disputes,as evidenced in the full-process management covering pre-during-post disputes.The administration guided the hospitals in their dispute resolution,and included resolution rate of disputes as an index of municipal hospital performance evaluation.By means of the guidance of such evaluation, medical disputes and major medical accidents have been resolved satisfactorily,and fine management of service quality of such hospitals in terms of medical service,pharmacy,nursing and medical technology has been intensified all the time.

To shorten the cultivation time and reduce the consumption of raw materials for microbial lipid production, oleaginous yeast Rhodosporidium toruloides AS 2.1389 was cultivated using a two-stage culture mode, in which the cell propagation and lipid accumulation were separated. The yeast cells recovered from the propagation culture were re-suspended in glucose solution for lipid accumulation, through which lipid content over 55% of the dry cell weight was achieved, the longer the propagation stage was, the higher the lipid content. Analysis of the lipid indicated that the long-chain fatty acids with 16 and 18 carbon atoms were major components, suggesting that the lipid can be an alternative feedstock for biodiesel production.

Objective:To investigate the expression of INHBA in colorectal cancer and its relationship with microsatellite status and clinicopathological features.Methods:Bioinformatics analysis was conducted based on Gene Expression Omnibus (GEO) database and Gene Expression Profiling Interaction Analysis (GEPIA) database, and the differentially expressed prognosis-related target genes in colorectal cancer were selected. Wax mass tissues of 107 patients with colorectal cancer who underwent surgery from January 2016 to June 2022 in the Third Affiliated Hospital of Jinzhou Medical University were collected, and the tissue microarrays were prepared. The clinicopathological microsatellite status [positive expressions of the mismatch repair (MMR) proteins MLH1, MSH2, MSH6, and PMS2 were mismatch repair proficient (pMMR), which represented low microsatellite instability or microsatellite stabilization; if any of these indexes was negative, it was judged to be mismatch repair deficient (dMMR), which represented high microsatellite instability] and INHBA expression in colorectal cancer tissues were detected by immunohistochemistry, data of the patients were retrospectively analyzed. The relationship between INHBA and microsatellite status as well as clinicopathological features was analyzed.Results:Three data sets of colorectal cancer were selected from GEO database: GSE110223 (13 cancer tissues, 13 paracancerous tissues), GSE110224 (17 cancer tissues, 17 paracancerous tissues), GSE113513 (14 cancer tissues, 14 paracancerous tissues), and the top 50 genes that were differentially up-regulated and down-regulated between cancer tissues and paracancerous tissues were screened. Intersection genes of 3 data sets were analyzed by Venn diagram, and 12 up-regulated genes and 17 down-regulated genes were screened out. According to GEPIA database, AQP8, ZG16 and INHBA genes among the up-regulated and down-regulated differential genes were associated with the prognosis of colorectal cancer. INHBA was higher expressed in colorectal cancer tissues than in paracancerous tissues (≥5 cm from the tumor margin) ( P < 0.05), and INHBA gene was selected for analysis. Immunohistochemical detection of collected colorectal cancer wax samples showed that the proportion of patients with high INHBA expression in colorectal cancer tissues was higher than that in paracancerous tissues [85.05% (91/107) vs. 67.29% (72/107), P < 0.05]. The high expression of INHBA in cancer tissues was related to the lesion site [right colon vs. left colon: 94.00% (47/50) vs. 77.19% (44/57)], maximum tumor diameter [>5 cm vs. ≤5 cm: 92.73% (51/55) vs. 76.92% (40/52)] and the depth of invasion [stage T 3-4 vs. stage T 1-2: 96.43% (54/56) vs. 72.55% (37/51)], differentiation degree [low and medium differentiation vs. high differentiation: 91.04% (61/67) vs. 75.00% (30/40)], lymph node metastasis [yes vs. no: 93.02% (40/43) vs. 78.13% (50/64)] (all P < 0.05), but had no correlation with age, sex, thrombus and nerve invasion (all P > 0.05). The proportion of patients with high expression of INHBA in colorectal cancer tissues in pMMR group was higher than that in dMMR group [93.22% (55/59) vs. 75.00% (36/48), χ2 = 6.91, P = 0.008]. Conclusions:INHBA is highly expressed in colorectal cancer tissues, and the highly expressed INHBA is closely related to clinicopathological features and microsatellite status of colorectal cancer. INBHA may be a new target for diagnosis, treatment and prognosis of colorectal cancer.
