Objective To explore the role and their relationship of Ki-67, VEGF and p27 expressed in adult patients with acute leukemia. Methods The expression of Ki-67, VEGF and p27 in bone marrow mononuclear cells (BMMNC) were analyzed by immunocytochemical staining, and their correlations of Ki-67, VEGF and p27 were statistically analyzed. Results The expression of Ki-67(42.48±25.78)% or VEGF (44.89±24.01)% on BMMNC from acute leukemia cells was significantly higher than that in the control (11.40±9.94)% or (16.90±12.54)% (P<0.01). But the expression of p27 (23.65±13.30)% was significantly lower than that in the control (50.23±22.68)% (P<0.01). The expressions of Ki-67 were positively correlated with and VEGF in patients with acute leukemia were positively correlated(r=-0.666, P<0.01), and the expressions of Ki-67 and p27 were negatively correlated with p27 in patients with acute leukemia (r=-0.316, P<0.05).Conclusion The evaluation of expression of Ki-67, VEGF and p27 on acute leukemic cells provides new insights to the pathogenesis is helpful in mechanism and is helpful in the diagnosis of acute leukemia.

Objective To observe the protective effects of various extracts from Flos Daturae (FD), including active fraction (AF-FD), withanolides constituents (WC-FD), and flavonoids constituents (FC-FD) on Chinese hamster ovary (CHO) cells against cytotoxicity induced by DMSO. Methods The survival rate of CHO cells was examined by MTT assay and LDH leakage assays. Results Using MTT assay, coincubation of CHO cells with 3% DMSO for 24 h resulted in a significant reduction of survival rate of CHO cells. AF-FD was tested in a range of 10—80 ?g/mL to improve the survival rate of CHO cells in a dose-dependent manner. FC-FD (2.5—20 ?g/mL), but not WC-FD (30—120 ?g/mL), could significantly relieve the injury induced by 3% DMSO in CHO cells. In the measurement of LDH leakage, coincubation of CHO cells with 4.5% DMSO for 24 h obviously increased LDH release. However, all the compounds tested, including AF-FD (10—80 ?g/mL), WC-FD (30—120 ?g/mL), and FC-FD (2.5—20 ?g/mL) had no effect on LDH leakage induced by 4.5% DMSO. Conclusion The findings suggest that the FC-FD may protect CHO cells from DMSO cytotoxicity assessed by MTT assay, which may be associated with improving mitochondrial function, but not protecting the membrane injury of CHO cells.

Objective:
To learn the trend of death from injury in Fengcheng residents from 2009 to 2017 and predict from 2018 to 2021,in order to provide the basis for injury prevention and control.
Methods:
All cause of death monitoring data and demographic data of Fengcheng from 2009 to 2017 were collected,injury mortality,standardized mortality and annual change percentage(APC)were calculated,and GM(1,1)was established to predict the injury mortality from 2018 to 2021.
Results:
From 2009 to 2017,the injury death rate in Fengcheng was 52.68 per 100 000 and the standardized death rate was 46.50 per 100 000. The APC of the total standardized mortality was -5.10%,showing a decreasing trend year by year(P<0.05). The injury mortality and standardized mortality in males were higher than that in female(both P <0.05). The highest injury mortality lay in the group aged 65 years and above,which was 108.13 per 100 000. The top five causes of injury death were traffic accident,suiside,poisoning,fall and drowning,their mortality rate were 27.03 per 100 000,7.84 per 100 000,5.62 per 100 000,5.08 per 100 000 and 2.36 per 100 000,respectively. The mortality of traffic accident in males and suicide in females showed a decreasing trend(P<0.05),while the mortality of fall showed an increasing trend(all P<0.05). The model of GM(1,1)predicted that the injury mortality from 2018 to 2021 would be 48.00 per 100 000,44.15 per 100 000,40.61 per 100 000 and 37.35 per 100 000,which showed a decreasing trend year by year.
Conclusion
The injury death rates in Fengcheng dropp year by year from 2009 to 2017 and will probably keep dropping from 2018 to 2021. Men and people aged 65 years or over are at high risk of death from injury,traffic accident and fall are the main causes.

OBJECTIVETo identify pathological mutation in a Chinese male infant featuring oculocerebrorenal syndrome (also called Lowe syndrome).
METHODSClinical data of the patient were collected. DNA was extracted from peripheral blood of the infant and his parents. All of the 24 exons and intron-exon splice sites of OCRL gene were amplified with PCR. Mutations were detected by direct sequencing the PCR products.
RESULTSThe infant was found to have carried a c.1499G>A (p.R500Q) mutation in exon 15 of the OCRL gene, which was transmitted from his mother, who was heterozygous for the same mutation. The c.1499G>A mutation, discovered in Chinese population for the first time, has been reported to cause severe Lowe syndrome in other ethnic populations.
CONCLUSIONThe c.1499G>A mutation of the OCRL gene is probably responsible for the disease in the patient. Further study of this mutation may facilitate delineation of the genotype-phenotype correlation of this disease.

OBJECTIVE:
Comparison of the sensitivity of Sp/Ap amplitude and area ratio in the aid of diagnosis of Meniere's disease. Meniere's disease was defined by the 1995 American Academy of Otolaryngology-Head and Neck Surgery Committee on Hearing and Equilibrium.
METHOD:
The study sample consisted of 35 patients in our hospital, who were undergone tympanic electrocochleography (EcochG). A control group of 10 patients (20 ears) with normal Sp/Ap ratio and EcochG data were identified. Sp/Ap amplitude and area curve ratios for both group were measured.
RESULT:
The traditional upper limit and the upper limit of normal for Sp/Ap amplitude and area curve were respectively 0.4, 46 and 1.94. Of 35 patients with Meniere's disease, had an abnormal Sp/Ap amplitude ratio,and had an abnormal Sp/Ap area curve ratio; the difference between groups was statistically significant.
CONCLUSION
Sp/Ap curve area curve ratio is more sensitive than conventional Sp/Ap amplitude ratios in diagnosis of Meniere's disease.

Objective:To compare the clinical characteristics and analyze the prognostic factors between human immunodeficiency virus (HIV)-infected patients and non-HIV-infected immunocompromised patients with pneumocystis pneumonia (PCP) complicated with acute respiratory failure (ARF) in intensive care unit (ICU).Methods:The clinical data of patients with PCP complicated with ARF admitted in ICU of The First Affiliated Hospital of Zhengzhou University and The Sixth People′s Hospital of Zhengzhou City between May 2018 and October 2020 were retrospectively reviewed. All subjects were divided into HIV-infected group and non-HIV-infected immunocompromised group. General characteristics and underlying diseases of patients in the two groups were analyzed. Laboratory parameters, treatment and outcomes between two groups were compared. Independent sample t test, Mann-Whitney U test and chi-square test were used for statistical analysis, and univariate and multivariate logistic regression models were used to identify the risk factors for the clinical outcome. Results:A total of 129 PCP complicated with ARF patients were enrolled, including 75 HIV-infected patients and 54 non-HIV-infected immunocompromised patients. Only 10.7%(8/75) patients of HIV-infected group received anti-retroviral therapy (ART), but none of the patients in either groups had previously received trimethoprim-sulfamethoxazole (TMP-SMX) for PCP prophylaxis. Acute physiology and chronic health evaluation (APACHE) Ⅱ score of HIV-infected group was 18.7±6.0, which was higher than that in non-HIV-infected immunocompromised group (13.1±4.4) when admitted in ICU ( t=-5.45, P<0.001). Hypoproteinemia was common in both groups. Ninety-six percent (72/75) of HIV-infected patients had CD4 + T lymphocyte counts lower than 200/μL and 84.0%(63/75) of patients had CD4 + T lymphocyte counts even lower than 50/μL, while 5.74%(31/54) of patients in non-HIV-infected immunocompromised group had CD4 + T lymphocyte counts lower than 200/μL. The CD4 + /CD8 + T lymphocyte counts ratio was 0.05(0.02, 0.12) in HIV-infected group, which was lower than that in non-HIV-infected immunocompromised group (0.96(0.64, 1.44)), and the difference was statistically significant ( Z=-9.16, P<0.001). The length of ICU stay and hospital stay of non-HIV-infected immunocompromised patients were 10.0(7.0, 14.0) days and 18.0(11.8, 32.5) days, respectively, which were both longer than those in HIV-infected patients (7.0(4.0, 9.0) days and 13.0(7.0, 23.0) days, respectively), and the differences were both statistically significant ( Z=-3.58 and -2.73, respectively, both P<0.050). The hospital mortality of HIV-infected patients was 57.3%(43/75), which was significantly higher than that in non-HIV-infected immunocompromised patients (38.9%, 21/54) ( χ2=4.27, P=0.039). Multivariable logistic regression identified that lactic dehydrogenase (LDH), C-reactive protein (CRP) and APACHE Ⅱ score were the risk factors for the clinical outcome of HIV-infected patients (odds ratio ( OR)= 1.006, 1.015 and 1.736, respectively, all P<0.050). The partial pressure of oxygen in arterial blood/fractional concentration of inspiratory oxygen (PaO 2/FiO 2), LDH and CD4 + T lymphocyte counts were the risk factors for the clinical outcome of non-HIV infected immunocompromised patients ( OR=0.970, 1.008 and 0.989, respectively, all P<0.050). Conclusions:PCP patients with ARF are critically ill with high mortality rate. LDH, CRP and APACHEⅡscore are predictors for prognosis of HIV-infected patients with PCP, while PaO 2/FiO 2, LDH and CD4 + T lymphocyte counts are predictors for prognosis of non-HIV infected immunocompromised patients with PCP.
