Objective To discuss the influence of psychological nursing on the therapeutic effect of patients with newly diagnosed type 2 diabetes. Methods Patients (60 cases) who received psychological nursing were set as the nursing group. Patients (65 cases) who did not received psychological nursing were set as the control group. The number of patients who received early insulin treatment and whose fasting plasma glucose return to normal value on the 7th and 30th days after treatment was observed. Results The number of patients who received early insulin treatment and whose fasting plasma glucose return to normal value on the 7th and 30th days after treatment in the nursing group was higher than that of the control group (P<0.01). Conclusions Psychological nursing of patients with newly diagnosed type 2 diabetes could make patients obey doctors' advice and accept early insulin treatment to control plasma glucose and delete the toxicity of high concentration of plasma glucose as soon as possible.

Objective To establish a model to predict the cell-cycle process in response to ionizing radiation.Methods Human choroidal malignant melanoma 92-1 cells were used and the cell cycle distribution of cells was analyzed in 0-96 h after exposure to X-rays.A phenomenological model was constructed based on biological knowledge to describe the cell cycle dynamics in experiments.Results In the present study,a phenomenological model was constructed to describe the cellcycle dynamics of synchronized 92-1 cells in responding to various doses of ionizing radiation.The simulation results obtained with the model were consistent with the experimental data,demonstrating that the model had a good expansibility and could be used to predict the dynamics of cell cycle in responding to ionizing radiation.Further theoretical modeling of the cellcycle dynamics was made and the results were consistent with the simulation.Conclusions A phenomenological model was constructed which could be used to describe the dynamics of cell cycle of cells exposed to ionizing radiation and was supported by the experimental data.Because this model is easy to run by the written code,it has a good expansibility for studying the behaviors of cell populations under various conditions.

Objective To establish a new method for quantitating leukocyte fragments (LFs) in apheresis platelet concentrates (AP-PCs) by using real-time quantitative polymerase chain reaction (RQ-PCR) and flow cytometry(FCM) and discuss the factors influencing LFs concentrations such as storage time, filtration and PLT concentration. Methods 67 qualified donors were selected. Each of them donated one therapeutic dose of AP-PCs. AP-PCs samples were collected as soon as possible and divided into si xfractions. One was analyzed by hematology analyzer. For the Others, DNA was extracted under differen tconditions (filtrated or unfiltrated, before or after centrifugation) at 4 hours, 24 hours, 48 hours, 72 hours, 96 hours after blood draw, respectively. Then the amounts of albumin gene of the AP-PCs and the cell-free DNA in supematant were quantitatively determined using RQ-PCR and the results were calculated into leukocytes equivalent(WBCs/μl). Intact leucocytes were counted by FCM. The concentrations of LFs were calculated by subtracting cell-frce DNA and intact leucocytes from the total DNA amount. Then the differences of LFs concentrations among groups with different storage time were compared and the differences of LFs concentrations between unfihrated and filtrated groups were also compared. After grouping all the AP-PCs according to their PLT concentrations, LFs contents of AP-PCs before filtration among groups were compared. Meanwhile, bivariate correlation analysis between PLT concentrations and LFs contents was carried out. ResultsLFs contents of all the AP-PCs samples were quantitated successfully.The concentrations of LFs in AP-PCs before filtration in 4 hours,24 hours,48 hours,72 hours , 96 houres after blood draw were(31.4±17. 6), (47.5±25.3), (100.7±53.5), (89.5 ±47.2) and (16.1±7.8) WBCs/μl ; After filtration the results were (16. 9±8. 7), (24. 3 ± 12. 2), (83. 1±42. 6), (78.2 ±40. 2) and (13.6 ± 6. 6) WBCs/μl respectively. There were statistically significant differences among groups of different storage time (Fwithin subjects = 472. 756,P < 0.01). The concentrations of LFs kept on increasing within 48 hours after collections, and then decreased gradually. The peaks appeared between 48 hours and 72 hours after collections. The differences of LFs contents between unfiltered and filtered AP-PCs in 4 hours, 24 hours, 48 hours, 72 hours, 96 hours after collections were 14. 5, 23. 2, 17. 6, 11.3 and 2. 5 WBCs/μl, respectively.There was statistically significant difference between unfiltered and filtered samples (Fbetween subjects=9. 216,P < 0. 05). The differences were considerable within 48 hours, and then declined gradually. The results of bivariate correlation analysis showed that there were no statistically significant correlation between PLT concentrations and LFs contents (at 4, 24, 48, 72, 96 hours after collections the correlation coefficients rs were -0.002, 0.015, 0.027, 0.042 and 0. 037,respectively,P2-tailed>0.05). ConclusionsRQ-PCR and FCM can be used to quantitate LFs in AP-PCs. The concentration of LFs in AP-PCs is influenced by storage time and filtration, but it is not affected by PLT concentration.

Objective To explore the feasibility of fluorescence quantitative PCR(FQ-PCR)in prenatal diagnosis of the fetal RhD genotyping using free DNA from RhD-negative pregnant women.Methods The fetal RhD gene was amplified from 78 RhD-negative pregnant women with single fetus maternal plasma (gestation from 11 to 40 weeks).Rhe existence of fetal DNA was confirmed by amplification ofnine different polymorphic short tandem repeat loci(STR)and sex-determining region Y chromosome(SRY)gene.Exon5,7,10 and intron 4 were amplified by real-time polymerase chain reaction with TaqMan probe.The results of fetal RhD genotyping were evaluated retrospectively by the serologic analysis of infant cord blood.Results Among the 78 specimens,the SRY positive signals were detected from samples of 41 and were all identified male fetal through 8ex observation after newborn infants delivered from the women enrolled.The mean concentration of SRY gene reached(214.7±120.9)eopies/ml.RhD genotyping results of 70 cases were in complete concordance with the resets through serological detection of fetal cord blood after delivery.In addition,5 cases were false-positive.3 cages were considered inconclusive.The coincidence rate was 90%(70/78).From 5 false-positive cases,4 cases were identified as RhDel phenotype by detecting RHDl227A allele gene.The final accuracy rate of FQ-PCR was 95%(74/78)in the fetal RhD genotyping.Conclusion FQ-PCR analysis for noninvasive prenatal of fetal RhD genotyping could be useful in prevention and diagnosis of hemolytic disease of newborn.

AIM: To study the anti-inflammatory effect of the Antivirus Oral Liquid(AOL) in experimental rabbit conjunctivitis model. METHODS: Rabbit's staphococcus aureus conjunctivitis models and cantharides tincture conjunctivitis models were made to observe different groups of animals' symptom of eye stimulation,negative rate of bacteria and conjunctiva histopathology.And then AOL compared with the effect of amphemycin gutta or Shumu(gutta.) RESULTS: It showed that AOL possessed significant anti-inflammatory effect on bacterial conjunctivitis.The negative rate of bacteria was more than 90% after being given AOL for 4 days successively.Compared with the models group,the hyperemia and edemda were markedly relieved.The result showed that AOL possessed significant anti-inflammatory effect on irritable conjunctivitis.The hyperemia and edema were markedly relieved at the second day after being given AOL,and the inflammatory symptoms had almost disappeared after being given AOL for 4 days successively. CONCLUSION: AOL has a good effect on the therapy of staphylococcus aureus conjunctivitis and cantharides tincture.

Objective: To explore the impact of weight management and related medication intervention based on body weight changes on cardiac function among patients with chronic congestive heart failure (CHF). Methods: Using prospective, randomized, controlled study methods, consecutive CHF patients, who hospitalized in our department from June 2014 to June 2016 (n=350), were randomly divided into intervention group (n=175) and control group (n=175). Patients in the intervention group received weight management guidance and the post discharge diuretic drugs regimen was adjusted based on body weight changes. The control group received routine medical care post discharge. Left ventricular ejection fraction (LVEF), B type natriuretic peptide precursor (NT-proBNP), 6 minutes walk distance and NYHA classification at one day before discharge and after 6 months were compared between the two groups respectively. Results: Follow-up visit data were not available from 6 patients in the control and intervention group respectively. NYHA classification, LVEF, NT-proBNP and 6 minutes walk distance were similar between the two groups at one day before discharge (all P>0.05). After 6 months, the LVEF and 6 minutes walk distance were significantly higher while NT-proBNP level was significantly lower in the intervention group compared to the control group (all P<0.01). Meanwhile, the LVEF and 6 minutes walk distance were significantly increased, while NT-proBNP was significantly reduced at 6 months post discharge compared to one day before discharge in the intervention group (all P<0.01). The LVEF was also significantly improved (P=0.035), but the NT-proBNP and 6 minutes walk distance were similar (P were 0.328 and 0.807 respectively) at 6 months after discharge compared to one day before discharge in the control group. The NYHA classification was significantly lower in intervention group and in control group at 6 months after discharge compared to one day before discharge (Z=5.154, P<0.01 and Z=10.497, P<0.01), and the NYHA classification improved more in the intervention group than in control group at 6 months after discharge (Z=9.235, P<0.01). The re-hospitalization rate of CHF patients in intervention group was 11.83% (20/169), which was significantly lower than the control group (33.14% (56/169), χ²=21.99, P<0.01). At 6 months follow up, body weight remained unchanged in the intervention group, while body weight tended to be higher in the control group compared to one day before discharge. Conclusion The weight management and diuretic drug regimen adjudgment intervention based on body weight changes can improve cardiac function and reduced re-hospitalization rate in CHF patients.

Mini-Mental State Examination score in the study group was significantly higher than that in the control group [(28.87 ± 0.85) points vs. (27.91 ± 1.45) points, t = 4.197, P < 0.05]. National Institute Health of Stroke Scale score in the study group was significantly lower than that in the control group [(9.63 ± 2.19) points vs. (15.27 ± 1.97) points, t = 14.070, P < 0.05]. Conclusion:Shenqi Fuzheng Injection combined with nimodipine can remarkably improve the neurocognitive function, hemorheology and T cell subsets in patients with cerebral infarction in the convalescent phase. The combined method is safe and reliable, and its curative effect is stable.

In December 2019, a cluster of patients with pneumonia of unknown cause were linked to a seafood wholesale market in Wuhan, China. Some studies found that the virus was a new kind of virus which had never been found in the human body. Then, the virus was named 2019 novel coronavirus (2019-nCoV) by the World Health Organization (WHO). 2019-nCoV nucleic acid detection is one of the essential indicators of COVID-19. Recently, some false-negative cases in China-Japan Friendship Hospital and Hangzhou Hospital led the clinical doctors to question the value of the nucleic acid detection. In this paper, more than 3 000 results of 2019-nCoV detection in Zhongnan Hospital, Wuhan University were analyzed. Attention should be paid to the root cause of false-negative results and the related countermeasures should be taken.
