ObjectivesTo study the current status of child neglect and its inlfuencing factors in children aged 3-6 years in rural Henan.MethodsScales and evaluation methods in the Chinese rural child aged 3-6 years neglected eval-uation model were applied in this study. The neglect rate and the neglect degree were used to describe the neglect status of rural children aged 3-6 years in Henan. The inlfuencing factors for child neglect were also analyzed. ResultsThe total neglect rate in 450 enrolled children was 37.1% (167/450). The total neglect degree was 51.9±6.5. The boys had signiifcant-ly higher neglect rate than girls (P<0.05). There was no significant difference in neglect degree between boys and girls (P>0.05). There were significant differences in neglect rate and neglect degree among the different age groups (P<0.05), the higher neglect rate and higher neglect degree over age. The neglect rate and neglect degree in nuclear families and fam-ilies with three generations were lower than those in single-parent families and remarried families (P<0.05). The neglect rate and neglect degree in non-only children were higher than those in only children (P<0.05). The left-behind children had signiifcantly higher neglect rate and neglect degree than children living with parents (P<0.05). Based on multivariate logis-tic regression analysis, the risk factors of child neglect were single-parent families (OR = 4.78, 95%CI : 2.10-10.87) and remarried families (OR=4.53, 95%CI : 1.99-10.01). The protective factors of child neglect were parents working on sci-ence (OR = 0.20, 95%CI : 0.10-0.67) and living with parents (OR = 0.03, 95%CI : 0.00-0.54).ConclusionsThe neglect status is serious in Henan rural children, particularly in left-behind children.

Objective:To investigate the clinical effect of linezolid combined with levofloxacin in the intensive treatment of tuberculous meningitis.Methods:Seventy-six patients with tuberculous meningitis who underwent intensive treatment from May 2015 to April 2018 in the Fourth People's Hospital of Taiyuan were included in this study. They were assigned to a control group ( n = 38) and an observation group ( n = 38) according to treatment methods. The control group was given conventional treatment (isoniazid + rifampicin + pyrazinamide + ethambutol). The observation group was given treatment with linezolid combined with levofloxacin based on conventional treatment. All patients were treated for 8 successive weeks. Clinical efficacy was compared between the two groups. Results:Total effective rate and the incidence of complications were 92.11% (35/38) and 5.26% (2/38) respectively in the observation group, and they were 68.42% (26/38) and 23.68% (9/38) respectively in the control group. There were significant differences in total effective rate and the incidence of complications between the two groups ( χ2 = 6.727 and 5.028, both P < 0.05). After treatment, white blood cell count, blood glucose level, and protein level were (30.21 ± 4.16) × 10 6/L, (3.65 ± 0.32) mmol/L and (0.79 ± 0.05) g/L, respectively in the observation group, while they were (54.28 ± 6.42) × 10 6/L, (2.18 ± 0.21) mmol/L, (0.98 ± 0.21) g/L, respectively in the control group. There were significant differences in white blood cell count, blood glucose level and protein level between the two groups ( t = 19.396, 23.675, 4.538, all P < 0.05). There was significant difference in the score of quality of life between the control and observation groups [(187.59 ± 4.11) points vs. (216.94 ± 3.90) points, t = 31.933, P < 0.05]. Conclusion:Linezolid combined with levofloxacin based on conventional treatment exhibits better clinical efficacy with high safety in the intensive treatment of tuberculous meningitis than conventional treatment.

Objective To assess the predicting value of homocysteine ( HCY), low density lipoprotein cholesterin (LDL-C) and carotid intima-media thickness (IMT) for women with coronary artery disease (CAD). Methods To choose 115 patients with CAD and 102 patients of non-CAD;Homocysteine, LDL-C and IMT were assayed respectively;comparison and correlation analysis were performed based on genders. Results The rates for hyperhomocysteinemia and High Lipoproteinaemia in female CAD patients are 59. 6% and 75.0%,respectively,while they are 69. 9% and 78.6% for male CAD patients,which are both remarkably higher than 23.0% ,26.7%, 22. 2% and 23.6% in non-CAD patients ( Ps ＜ 0. 05 ). ROC curve shows that the best diagnostic boundary point is 0.953 mm for female IMT and 1. 021 mm for male IMT. At the boundary point,the sensitivity,specificity,positive predictive value and negative predictive value are 83.7% ,91.4% ,95.7% and 63. 8% in female, much higher than 62.9%, 65.3%, 76.2% and 53.3% in male. Conclusion hyperhomocysteinemia, high lipoproteinaemia are the important risk factors for women with coronary artery disease;IMT might be used as the predictor of CAD, which have more advantages for female than for male patients.

Objective:To study the effect of retinoic acid(RA) which is used in malignant tumor therapy on the secretion of C3 and factor B in human lung cancer cell line A549 induced by TNF-? and IL-6.Methods:C3 and factor B in the culture medium were measured by ELISA and Western blot,the mRNA expression of C3 and factor B was analyzed by RT-PCR.Results:When using TNF-?(10 ?g/L),IL-6(50 ?g/L) and RA(1 ?mol/L),the results of ELISA,Western blot and RT-PCR showed that TNF-? and IL-6 promoted A549 cells excreting C3 and factor B and their mRNA expression;RA alone did not affect C3 and factor B;in TNF-? group and TNF-?+RA group,the amounts of C3 were 91.40?12.59 and 133.59?11.25(ng/10~6 cells) respectively(P0.05),and the amounts of factor B were 13.07?2.50 and 32.89?4.22(ng/10~6 cells) respectively(P

Objective To discuss the effect of interferon ?-2a on the radiosensitivity and cell cycle for nasopharyngeal carcinoma cell line CNE-I. Methods Interferon ?-2a was given by different concentration. Then the cells were radiated with X-ray (6?MV) and the cell survival rate was calculated. The change of cell cycle dynamics was measured with flow cytometry. Results The cell survival fraction was 0.62, 0.43 and 0.20 respectively after the interferon ?-2a was given by different concentration(0.5?106, 1.0?106 and 1.5?106?IU/L). The radiosensitization ratio was 1.16, 1.57 and 1.93 respectively. Compared with the control group, increasing cell percentage in G_1 and G_2+M phage and decreasing cell percentage in S phage were observed on 24 h after the interferon ?-2a(1?106?IU/L) was given(P

To explore the effects of Quyu Xiaoban Capsule (QXC) on blood lipid level and platelet activity in coronary heart disease (CHD).A randomized single blinded trial was adopted in 62 cases of CHD. Thirty one cases (control group) were treated with routine western medicine and the rest (QXC group) with QXC added. Serum levels of total cholesterols (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL C) and platelet-activating ? granule membrane protein (GMP 140) were detected before and after treatment.After ten weeks of treatment, GMP 140, TC and TG levels were decreased to various degrees in QXC group, the differences being significant as compared with those in control group and those in QXC group before treatment (P0 05).[Conclusion]QXC can decrease the blood lipid level and improve platelet activity and has a certain effect in preventing and treating CHD.

Soybean fungal root rot diseases are the most serious soybean disease problem in Heilongjiang province. The microbial seed dressing agent comprised of Bacillus strain B29 which showed strong antagonistic ability to the pathogens of Fusarium oxysporum, Pythium spp. and Rhizoctonia solani were applied to control soybean fungal root rot in field. The control efficiencies of the treatment T3, T4, T5, T6 on soybean fungal root rot after 35-day cultivation were 50.2%, 60.0%, 48.3%, 49.4% respectively, which were better than that of Carbendazim-Carbofuran-Thiram seed coating agent (T2). The second investigation after 50-day cultivation showed the control efficiency of T4 was the best (60.7%), while the control efficiency of T3 was not significantly different from T2. The control efficiencies of T5 and T6 were lower than that of T2. The microbial seed dressing agents were safe to soybean cultivation based on the investigation on seed germination rate, plant height, fresh weight and root nodules. The results based on 2-year demonstrating in field showed that soybean seeds germinating rate was more than 90% after seeds dressing by the microbial seed dressing agents, and the control efficiencies on soybean root rot diseases were 56.3% to 89.1%. It suggested that the microbial seed dressing agents were not only efficient to control soybean root rot diseases but also increased soybean productions.

Objective To explore the difference of the impact with different hydrosalpinx pretreatment methods in vitro fertiliza-tion-embryo transfer ﹝ IVF-ET ﹞.Methods 160 patients with routine IVF-ET’s hydrosalpinx were random divided into two groups :the first 80 patients undergoing routine bolt blocking the fallopian tubes for the study group;the other 80 patients with rou-tine salpingectomy as control group patients,after treatment,compare the difference on ovarian function between the two groups.Re-sults In the study group,although these difference,the average number of oocytes,fertilization rate,clinical pregnancy rate and other indicators,were not statistically significant (P>0.05),they were higher than the control group;early abortion rate was no significant difference either (P>0.05),but the tubal pregnancy rate was lower than the control group,and the difference was statis-tically significant (P<0.05).Conclusion Tubal bolt blocking technique is an effective method for hydrosalpinx pretreatment,and partly superior than gynecological surgery for keeping ovarian function and IVF-ET treatment targets.So,it has a broad application prospects in vitro fertilization-embryo transfer.
