The public ethics consciousness,with medical ethics included,fundamentally depends on the gradual improvement in the self-identity of human as objective itself.However,the improvement of humanistic consciousness is a long and painful process.Former recognition of historical culture,including the humanistic ideal in traditional Chinese ethical thoughts and systemic rational thoughts in modern western society,mainly employs transcendental test of abstract anthroposophy as its cultural premise,superficially enhancing certain individuals and their thoughts,motives,and objectives to historical ontology,but actually resulting in the absence of human individuals in realistic history.The self-conscious improvement of human-oriented public ethics can only be realized by the subjective humanistic consciousness which undergoes the regression from axiology,epistemology,to existence theory,making human realize that they themselves are the utmost purpose of all values and significances.

ObjectiveTo observe the effect of acupoints stimulation with silver spike point therapy on insomnia.Methods60 patients with insomnia were randomly divided into the trial group and control group with 30 cases in each group. Patients of the trial group were treated by acupoints stimulation with silver spike point therapy and patients of control group were treated only with Clonopin. All patients of two groups were tested with Self-Rating Scale of Sleep (SRSS) before and after treatment.ResultsThe curative effect rate of the trial group was 86.6%; that of the control group was 60%; the curative effect of the trial group was superior to the control group (P<0.05). SRSS difference of the trial group pre-and post-treatment was 12.79±3.20; that of the control group was 10.1±3.89. There was also a significant difference between two groups (P<0.01).ConclusionThe silver spike point therapy has the better curative effect on insomnia than Clonopin.

Aim To explore the proteomics mechanism of the differentiation induction effect of 4-amino-2-trif-luoromethyl-phenyl retinate(ATPR)on human leukemi-a K562 cells. Methods Human leukemia K562 cells were incubated with the same concentration (1 × 10 - 6 mol·L - 1 ) of ATPR or ATRA for 48 hours. The total cell proteins were collected, purified and digested by trypsin, solid phase extraction, and the peptides were detected by ESI-LC-MS / MS. The difference of the pro-tein expression between the cells treated with ATPR and ATRA was compared by using the Discoverer Pro-teome 1. 2 software, and the molecular function, the biological process and other information of those pro-teins were analyzed based on the DAVID, KEGG, STRING databases. Results 120 specific proteins were identified only in the ATPR group, 143 only in the ATRA group, and 422 other proteins in both groups. Results of DAVID analysis showed that ATPR-induced specific proteins were mainly involved in 39 biological processes of proteins and macromolecules metabolism, protein transport and localization and so on. Results of KEGG analysis revealed that ATPR-in-duced proteins participated in signal pathways, mainly metabolic pathways, PI3K-Akt signal pathway, TGF-beta signal pathway and other pathways in cancer. String protein interaction network analysis displayed that ATPR-induced proteins, like EIF3A, EIF6, RPL3, RPL8, RPL13, RPL7A, RPL21, RPS3, RPS14, NACA, BTF3, NHP2L1, PPP2CA proteins had direct interactions with more than or equal to 10 associated proteins. Conclusion The differentiation induction effect of ATPR on K562 cells might be as-cribed to the ATPR-induced proteins interaction net-work and the specific central proteins it induced, which are involved in the regulation of cell prolifera-tion, differentiation and apoptosis.

Objective:To observe the outcome of posterior staphyloma (PS) marginal retinal photocoagulation in pars plana vitrectomy (PPV) for high myopia macular hole retinal detachment eyes accompanied with PS.Methods:From January 2017 to June 2019, 49 patients (49 eyes) with high myopia macular hole retinal detachment accompanied with PS who were undergone PPV operation from Tianjin Eye Hospital were included in this study. There were 13 males (13 eyes) and 36 females (36 eyes). All patients underwent best corrected visual acuities (BCVA) and optical coherence tomography examinations. The standard logarithmic visual acuity chart was used for BCVA examination, and the visual acuity was converted to minimum resolution angle in logarithmic (logMAR) when recorded. The patients were randomly divided into two groups according to surgical options: conventional PPV with internal limiting membrane (ILM) peeling (group A, 24 eyes), PS marginal retinal photocoagulation in PPV with ILM peeling (group A, 25 eyes). The mean preoperative logMAR BCVA of group A and B were 1.87±0.28 and 1.80±0.37, the difference was not statistically significant ( t=0.604, P=0.551). The patients in the group A received 23G PPV, triamcinolone acetonide staining during the operation, the epiretinal membrane was peeled off, indocyanine green assisted staining, the posterior macular ILM was peeled off, and the peripheral retina was examined in detail during the operation. Areas with retinal degeneration were reinforced by laser photocoagulation, and the subretinal fluid was drained through the macular hole and filled with silicone oil. The eyes of the group B were subjected to retinal photocoagulation for 2 to 3 rows at the edge of the PS in addition to the usual surgical procedures. The average follow-up time was 8.34±3.21 months. Surgical outcome were estimated by the average number of operation, retinal reattachment rate, macular hole closure rate and BCVA. The χ2 test or Fisher exact probability was used to compare the count data. Independent sample t test was used to compare the measurement data. Results:Retinal reattachment was obtained in 17 eyes (70.8%, 17/24) and 24 eyes (96.0%, 24/25) in group A and B after first surgery respectively, the difference was statistically significant ( χ2=3.984, P=0.046). Final retinal reattachment was obtained in all 49 eyes. Final macular hole closure was in 15 eyes (62.5%, 15/24) and 19 eyes (76.0%, 19/25) in group A and B, respectively, the difference was not statistically significant ( χ2=1.051, P=0.305). The mean postoperative logMAR BCVA of group A (1.20±0.47) and B (1.08±0.39) were all improved than preoperative BCVA, the differences were all statistically significant ( t=2.899, 5.327; P=0.001, 0.000), the differences of mean postoperative logMAR BCVA between two groups was not statistically significant ( t=0.675, P=0.506). The mean number of operation of group A (2.63±0.88) was more than group B (2.08±0.28), the difference was statistically significant ( t=3.003, P=0.006). Conclusion:In comparison with conventional PPV, combined PS marginal retinal photocoagulation can improve retinal reattachment rate after first surgery, and reduce the number of reoperations.

Objective To investigate the correlation between antiphospholipid antibody syndrome and the early onset of preeclampsia. Methods From May 2010 to July 2013, one hundred and threecases in-patient treatment of the early onset preeclampsia were enrolled in this study. The maternal serum anticardiolipin antibodies(ACA)and anti-β2-glycoproteinⅠantibody (Aβ2-GPⅠ) were detected by ELISA method. 58 cases of pregnant women were randomly divided into the routine treatment group (30 cases) and the anticoagulant therapy group (28 cases). Results ACA positive predictive value of the early onset preeclampsia value was 3.9%. No significant difference was found in the prolonged anticoagulation of early onset preeclampsia time between the control group and the treatment group. Conclusion ACA may not be used to predict the early onset preeclampsia. Anticoagulation therapy can′t extend the early onset preeclampsia time and improve the outcome of pregnancy.

Structural modifications were performed with natural product of oleanolic acid to search for novel anticancer drugs. Ten oleanolic acid derivatives were designed and obtained by the reaction of oxidation, acylation or hydrolyzation, etc. The cytotoxic activity of derivatives was evaluated against HeLa, HepG2 and BGC-823 cells in vitro by MTT assay, gefitinib and etoposide used as a positive control. The results showed that compound 5a was particularly active to inhibit HepG2 cells growth, and anti-tumor activity of compound 7 on HeLa cells was significantly stronger than oleanolic acid. They are worthy to be studied further.

Objective To investigate the treatment measures of having trigeminocardiac reflex (TCR) for the primary trigeminal neuralgia via microvascular decompression.Methods From January 2016 to December 2016,the clinical data and anesthesia records of 79 consecutive patients with primary trigeminal neuralgia admitted to the Department of Neurosurgery,Xuanwu Hospital,Capital Medical University and treated the first craniotomy microvascular decompression were analyzed retrospectively.They were divided into a no TCR group (n=63) and a TCR group (n=16) according to the intraoperative anesthesia monitoring.The differences of baseline conditions,preoperative complications and pain involved the trigeminal nerve branches were compared between the two groups.The treatment measures and short-term prognosis of the patients with TCR during operation were summarized.Results (1) The proportion of hypertension in the TCR group was 31.2％ (n=5),it was higher than 7.9％ in the no TCR group (n=5).There was significant difference (χ2=6.273,P<0.05).(2) During the operation of microvascular decompression,16 patients in the TCR group had 19-time TCR.The baseline heart rate was 74±10/min before operation,and the heart rate decreased to 51±6/min at onset of TCR.The mean baseline arterial blood pressure was 102±13 mmHg,and the mean arterial blood pressure decreased to 74±8 mmHg at the onset of TCR.There was significant difference (P<0.05).(3) After the onset of TCR,the operation of was stopped,heart rate and the blood pressure recovered spontaneously (n=4).Fifteen patients were treated with medications,including using atropine (12 times,dose 0.2-0.5 mg) and ephedrine hydrochloride (3 times,dose 5-10 mg).Heart rate and blood pressure returned to the baseline level within 20 seconds or 20 seconds after administration of medications.There was no TCR-related cardiac complication or neurological deficit from after procedure to before discharge.Conclusions In microvascular decompression of primary trigeminal neuralgia,if TCR occurs,the selective use of anticholinergic agents or vasoactive agents is needed as early as possible.The risk factors for the occurrence of TCR need to be further verified.

Keshan disease was an endemic cardiomyopathy in China. The very low selenium intake of local people was considered to be an important causal factor. The main pathological characteristics of this disease was multifo-cal necrosis and fibrous replacement of myocardium that was scattered throughout the wall of all chambers.Two patterns of myocardial necrosis, myofibrillar pattern and mitochondrial pattern were distinguished in electron microscopy. The myofibrillar pattern was characterized by myofibril segmentation. It agreed well with the contraction band necrosis described in light microscopy. It was mainly seen in acute Keshan heart and might be related to circulatory disorders. Mitochondrial pattern was identical with myocytolysis of conventional pathology. It represented the typical lesion of Keshan disease.Mitochondria showed early and conspicuous changes in involved myo-cytes. Myofibrillar damage seemed to be secondary to the mitochondrial injury in the development of myocytolysis.Histochemical studies revealed that the acid phosphatase activity was obviously increased in muscle fibers surrounding the necrotic foci, and the succinic dehydrogenase activity was greatly reduced in damaged myocardio-cytes.
