1.ELECTRON MICROSCOPE STUDIES ON THE HISTOCHEMICAL LOCALIZATION OF ATPase AND SUCCINIC DEHYDROGENASE ACTIVITIES IN THE CANCER CELL OF THE MOUSE MAMMARY GLAND
Acta Anatomica Sinica 1957;0(04):-
This paper presents the results of the histochemical study on the activities ofATPase and succinic dehydrogenase and their distribution in mammary gland cancercell of mice by means of electron microscopy.It was found that the activity of ATPase activated by Mg~(++)were mainly locatedon the mitochondrial membrane,the nuclear membrane and the nucleolus,and that ofATPase activated by Ca~(++)were located on the cristae and matrix of mitochondria aswell as the outer nuclear membrane,and also evenly distributed in the chromatin.The activity of the succinic dehydrogenase is mainly located on the cristae andthe inner membrane of mitochondria.An alternitive responses of strong and weakactivities of the enzyme were shown between the outer and inner nuclear membranes.In the mean-while,the activity of the succinic dehydrogenase was also shown in ahigh level in the outer cytoplasmic membrane and the inner nuclear membrane.

In the present study, electron microscopic and cytochemical localization of succinic dehydrogenase (SDH) of the tumor-like growth tissue in the Tiger-head goldfish (Carassius aurtus) were attempted. The SDH was demonstrated according to the modified method described by Kerpel-Fronius and Hajos (1968). The main results are as follows:When the goldfish were twenty-months old, there was not only a highly active positive reaction of SDH on the periphery of jejune vesicle, but also on the mitochondria, cristae and cytoplasm membrane in the cells of the hyperplasitic tissue. At the same time, there were much crystal formation because cell disintegration. When the Tiger-head goldfish were ten and thirty-months old, the active reaction of SDH was not so strong as in the corresponding positions of cytodeme as When it was twenty-months old. The crystal formation were lesser than the others. But the control groups displayed the negative reaction of SDH in the corresponding positions.

Objective To assess the incidence and management of nocturnal acid breakthrough (NAB). Methods Forty patients with duodenal ulcer confirmed by gastroscopy were randomly divided into five groups, eight patients in each group. Patients were treated by the following strategies for a course of 5 days: group A (omeprazole 20 mg per day orally in the morning), group B (omeprazole 20 mg twice a day orally in the morning and at 4 p.m), group C (intravenous injection of omeprazole 40 mg twice a day in the morning and at 4 p.m), group D (omeprazole 20 mg per day orally in the morning plus ranitidine 150 mg at bed time) and group E (omeprazole 20 mg twice a day orally in the morming and at 4 p.m plus ranitidine 150 mg at bed time) respectively. Intragastric pH over 24 hours was recorded on the morning of the fifth day for each patient. Results In comparison with that in group A, intragastric pH was higher in the other four groups. The mean intragastric pH and mean nocturnal pH each in group B (6.2?0.7, 6.4?1.1), group C (6.9?0.7, 6.8?0.9), group D (6.0?0.7, 5.9?0.7) and group E (5.8?0.5, 6.1?0.5) were significantly higher than those in group A (4.8?0.7, 4.7?0.8, P

Idiopathic rapid eye movement (REM) sleep behavior disorder is recognized as a prodromal stage of α-synucleinopathies such as Parkinson′s disease, Lewy body dementia and multiple system atrophy. It is important to timely identify early predictors that can predict early conversion into α-synucleinopathies. This review provided an update on classic and novel early predictors of α-synucleinopathies in patients with idiopathic REM sleep behavior disorder and provided a comprehensive understanding on the phenotypic transformation of the disease.

Objective To investigate the clinical pathological characteristics and pattern changes of gastric polyps in the past 15 years.Methods From 1998 to 2012,the cases of gastric polyps diagnosed by gastroscopy were collected.Data of gender,age,location,number,size,Yamata type,pathological type,Helicobacter pylori (H.pylori) infection were retrospectively analyzed.The data were analyzed by Chi square test.Results Among 62 975 cases received gastroscopy,gastric polyps were detected in 2 643 patients and the gastric polyps detection rate was 4.20%,which of female (5.91%,1 790/30 269) was higher than that of male (2.61%,853/32 706).And patients aged ≥60 years old has a high prevalence of gastric polyps; the detection rate was 6.39%(1 124/17 590).The positive rate of H.pylori infection in patients detected with gastric polyp was 12.70% (321/2 527).Gastric body (40.41%,1 068/2 643) and fundus (26.79%,708/2 643) were two predilection sites of gastric polyps.About 69.05%(1 825/2 643) patients' polyps were solitary,74.76%(1 976/2 643) patients' polyps were less than 0.5 cm in diameter and mainly were Yamata type Ⅰ (30.68%,811/2 643) or type Ⅱ (54.41%,1 438/2 643).The common pathological types were hyperplastic polyps (43.80%,1 109/2 532),inflammatory polyps (34.24%,867/2 532),fundic-gland polyps (19.55%,495/2 532) and adenomatous polyps (2.41%,61/2 532).The detection rate of polyps gradually increased in the past 15 years.Between 1998 to 2002,2003 to 2007,2008 to 2012,the average of 5-year detection rates were 1.11%,2.50% and 6.49%,respectively.However,the proportion of pathological types didn't change significantly.Conclusions The detection rate of gastric polyps gradually increased year by year,and elderly woman is at high risk.Hyperplastic and inflammatory polyps ware the most common types.

Objective To study the effects of Genistein - magnetic - nanoparticles at different concentrations on the growth and ex-pression of focal adhesion kinase (FAK) in human hepatocellular carcinoma cell line HcpG2. Methods Activities of HepG2 cells treated by Genistein - magnetic - nanoparticles were examined by MTT assay. The expression of FAK mRNA and protein was respectively detected by immunohistochemistry staining and reversed transcriptase polymerase chain reaction (RT - PCR) . Results Genistein - magnetic -nanoparticles at a concentration of 10 -80mg/L inhibited the proliferation of HepG2 cells, with obvious concentration - dapendent and time - dependent effect relationships (P < 0.05). After treatment with various concentrations of Genistein - magnetic - nanoparticles for 48h, the relative level of FAKmRNA of Genistein - magnetic - nanoparticles and control groups was 1.242 ± 0.031,1.213 ± 0.443,0.834 ± 0.044,0.652 ± 0.039,0.446 ± 0.041, and 1.443 ± 0.053 (F = 21.97 ,P < 0.05), respectively. The expression of FAK protein in the cells was decreased, which showed an obvious a concentration - effect relationship. Conclusion Genistein - magnetic - nanoparticles can reduce the mRNA and protein expressions of FAK and inhibit the proliferation of HepG2 cells.

Objective To study the sedation and amnesia of midazolam in patients with different ages of lumbar epidural anesthesia . Methods From January to July 2015, 235 patients in the first affiliated of xian jiaotong unniversity,who were implemented abdominal surgery under combined spinal epidural anesthesia and American Society of anesthesiologists (ASA) grade was I-II , were divided into three groups:young group (n=70); middle-aged group (n =82); elderly group (n =83).Intraoperative continuous monitoring of respiratory and circulatory function index,and recorded MAP,SpO2, HR before and 5, 15, 30 min after injection.ResuIts MAP, HR and SpO2 of three groups were compared with the same time points pre-and post used of midazolam, there was no significant difference among indicators.; Compared with the same group at different time points, MAP(FYG =9.2547,FMG =12.8181,FOG =17.77)和 SpO2 (FYG =190.3835,FMG =196.2393,FOG =270.5609),there were significant difference.The difference was not statistically significant between HR group and the same group at different time points and forgetting degree and sedation score , but compared with OG,there were significant difference(P<0.05).The total number of adverse reactions in YG group and MG group was less than that of OG group(X2 =11.2516,X2 =10.4491, P<0.05).ConcIusion The effect of the same dose of midazolam on sedation and amnesia in patients with different ages of lumbar epidural anesthesia is different, and the degree of the effect of the elderly patients is significant,but will produce more adverse reactions.Therefore, in the combined spinal epidural anesthesia,it is necessary to consider the patient's individual differences, rational use of sedative and narcotic drugs.
