Objective To evaluate the accuracy of Sysmex XT-4000i automated hematology analyzer on neonatal leukocytes count and classification results.Methods 213 cases of neonatal blood specimens were analyzed respectively by Sysmex XT-4000i automated hematology analyzer and microscope counting and staining of two categories of methods.Results The instrument that immature granulocyte,primitive cell,shift to the left,three kind of tip in any one or more specimens have 112,accounted for 52.58% (112/213),and staining immature cell or shift to the left of the specimens was 91,accounted for 42.72% (91/213).The instrument to nucleated erythrocyte specimens were 109,accounting for 51.17% (109/213),and staining of nucleated erythrocyte were 66,accounting for 30.99% (66/213).Classify or classification of incomplete instrument failed to leukocytes were 11,ac-counting for 5.16% (11/213).When the specimens without nucleated erythrocytes interference or the number of nucleated eryth-rocytes is low [≤ 10/100 white blood cells(WBC)],Instruments on leukocyte count and manual counting results,there was not statistically significant differences between the two groups(P >0.05 ),when the sample number of nucleated erythrocytes (>10/100 WBC),When the specimens were nucleated erythrocyte number for a long time(>10/100 WBC),Instruments on leukocyte count and manual counting results,there was significant difference between the two groups(P <0.05).Correlation analysis on the instrument detection and manual dyeing classification of leukocytes,neutrophils,lymphocytes,monocytes,eosinophils,basophils, the correlation coefficient is respectively 0.95,0.93,0.78,0.86,0.14.Conclusion Some errors exist in Sysmex XT-4000i auto-mated hematology analyzer to count and classification of leukocytes.On neonatal blood tests should be carried out at the same time man-ual microscopy,and on the basis of nucleated erythrocytes were corrected,to ensure the clinical blood routine reporting results.

OBJECTIVE: To investigate the mechanism of the pulmonary injury in rats caused by chronic intermittent hypoxia (CIH) and to investigate the intervention effect of Edaravone. METHOD: Ninety-six male Wistar rats were divided into four groups randomly: the control group (NC), chronic intermittent hypoxia group (CIH), chronic intermittent hypoxia normal saline matched group (NS), chronic intermittent hypoxia edaravone treatment group (NE). The four groups were also divided into 1, 2, 3, 4 W time subgroups, and each time subgroup had 6 rats. After the experiment, sections of pulmonary were stained with hematoxylin-eosin (HE) and the level of SOD, MDA, PO2 and Ang II mRNA in rat homogenate pulmonary were measured. RESULT: Pulmonary histology revealed that the CIH group showed high levels of interstitial edema, alveolar atelectasis, inflammatory cell infiltration of alveolar epithelial cell, pulmonary injury were serious in 1, 2, 3, 4 W. But the pulmonary histology of the UC group and the NS group was normal. Compared with the NS group, pulmonary injury of NE group 1, 2, 3, 4 W, significantly decreased. Compared with the NC group, the levels of PO2 in the CIH group were decreased; while the compared with the NS group, the levels of PO2 in the NE group were increased. Compared with the UC group and NS group, the levels of Ang II mRNA in each time point in CIH group were increased gradually (P < 0.05), the content of MDA were increased in 1, 2, 3, 4 W (P < 0.05), they had reached the peak all at 4 W; while the SOD in each time point in CIH group were decreased gradually (P < 0.05) compared with that in UC group and NS group; The Ang II mRNA levels of CIH in pulmonary showed positive correlation with MDA [r = 0.782,P < 0.01]; while the Ang II mRNA levels of CIH in pulmonary showed negative correlation with SOD [r = - 0.904, P < 0.01]. CONCLUSION CIH can cause pulmonary injury through oxidative stress and activating Ang II, and Edaravone could prevent pulmonary injury induced by CIH through scavenging oxygen free radicals.

OBJECTIVE:To provide reference for better carrying out safe medication intervention for the empty-nest elderly.METHODS:Two communities with different levels of income and culture were collected from Pudong New District of Shanghai,i.e.new community A and traditional community B.By cluster sampling,69 and 110 empty-nest elderly were selected as respondents respectively.The questionnaire survey about drug storage and medication habits of the elderly was conducted.The data of the survey were analyzed statistically.RESULTS:A total of 69 and 110 questionnaires were sent out,and 44 and 63 questionnaires were recovered with effective recovery rate of 63.8％ and 57.3％,respectively.The rate of drug storage in families from traditional community B was higher than new community A (100％ vs.88.6％,P=0.010).The proportions of residents in two communities storing their drugs in special drawers were the highest (59.0％ and 57.1％).Nearly half of the surveyed households in 2 communities did not form the habit of regularly clearing stored drugs.The frequency of residents who cleared stored drugs in traditional community B was higher than those in new community A (P=0.009).Nearly more than 70％ of the residents threw their expired drugs to garbage and only 11％ to drug stores or community health service center.The proportion of residents who were used to reading drug instructions in new community A was higher than traditional community B (95.5％ vs.77.8％,P=0.024).The proportion of the residents consulted community doctors when they were puzzled by drug use in new community A was lower than traditional community B (56.8％ vs.76.2％);The proportion of the residents consulted physicians in major hospitals was higher than traditional community B (34.1％ vs.9.5 ％);there was statistical significance (P=0.034).The most popular health service for the residents in the new community A was the hotline for the drug use (65.9％),while the residents in traditional community B needed blood pressure and sugar monitoring service and set up the health records (41.3％).The proportion of the residents' following demands in new community A was higher than traditional community B:opening drug use hotline,publicizing the knowledge of diseases and medication and conducting lectures (P＜0.001,P=0.006,P=0.018).CONCLUSIONS:The proportion of drug storage in empty-nest families of two communities is in very high level,but drug storage methods,cleaning frequency are not satisfactory.There are still a small number of elderly people who do not have the habit of reading drug instructions.There are some differences between the old and new communities.At the same time,the needs of health services in new and old communities are different.

Objective:To explore the effect of dialectical diet on traditional Chinese medicine (TCM) syndrome score of cirrhotic ascites patients based on "Gu Ben Kai Qu" theory.Methods:From March 2019 to January 2020, 84 patients with liver cirrhosis and ascites admitted to Shuguang Hospital Affiliated to Shanghai University of TCM were randomly divided into two groups according to the different dialectical types of the subjects, 14 cases in each group. Three non-syndrome differentiation diet groups were given routine nursing care of liver cirrhosis ascites. On the basis of routine nursing, the corresponding medicinal diet was selected according to syndrome differentiation based on "Gu Ben Kai Qu" theory. Patients with spleen and kidney yang deficiency syndrome selected Shenqi lean meat decoction. Patients with Yin deficiency of liver and kidney selected Wolfberry and ophiopogon spareribs decoction. Patients with qi stagnation and blood stasis syndrome selected Danggui Sanqi spareribs decoction. The TCM syndrome score scale for liver disease and the curative effect evaluation of cirrhosis ascites were used to evaluate the effect.Results:Eighty effective cases were included. On the first day of admission, the 14th day and the second week after discharge, the TCM syndrome scores of liver disease were as follows: the group (a1b1) with the spleen and kidney yang deficiency syndrome was 46.38±8.56, 34.20±8.42, 31.40±4.22, respectively. The group (a1b2) with the liver kidney yin deficiency syndrome was 41.50±8.71, 31.35±8.63, 31.12±4.94. The group(a1b3) with the qi stagnation and blood stasis syndrome was 45.92±7.86, 35.17±7.57, 30.83±7.32, respectively. The non-syndrome differentiation diet group (a2b1) with the spleen and kidney yang deficiency syndrome was 46.29±8.38, 39.79±7.65, 36.64±6.83, respectively. The non-syndrome differentiation diet group (a2b2) with the liver and kidney yin deficiency syndrome was 40.50±8.12, 38.10±8.93, 35.38±8.24, respectively. The non-syndrome differentiation diet group (a2b3) with the qi stagnation and blood stasis syndrome was 45.62±7.99, 41.83±7.31, 38.83±7.96, respectively. The comparison of TCM syndrome scores of liver disease at three time points was statistically significant ( χ2 value was 63.998, P<0.05), and the comparison between groups was statistically significant ( χ2 value was 20.993, P<0.05). On the 14th day and the second week after discharge, there were significant differences between the groups with the syndrome differentiation diet and another three groups with non-syndrome differentiation diet ( F values were 3.244, 3.489, all P<0.05). Conclusions:Based on the theory of "strengthening the foundation and opening channels", the syndrome differentiation group can effectively reduce the TCM syndrome score of patients with cirrhosis ascites, improve the symptoms and enhance the curative effect. With the development of time, the score of TCM syndrome in patients with liver disease become lower. On the 14th day of admission, patients with Yin deficiency of liver and kidney given medicated diets had significant effect; patients with spleen kidney yang deficiency syndrome or qi stagnation and blood stasis had significant effect in 2 weeks after discharge; which can effectively improve the clinical symptoms of patients with cirrhosis ascites to worthy of clinical application.

Objective:To explore the therapeutic mechanism of fractional laser combined with pulsed dye laser and multi-point microinjection of triamcinolone in the treatment of hypertrophic scars in rabbit ears.Methods:In this study, 80 hypertrophic scar models of rabbit ears were made and randomly divided into 4 groups: control group, laser combined group, laser combined multi-point microinjection group, simple traditional injection group, 20 scar models in each group.The control group was not given treatment; the laser combined group was treated with pulsed dye laser first, followed by fractional laser at the same time; the laser combined with multi-point microinjection group was treated with pulsed dye laser and fractional laser first, followed by multi-point microinjection of triamcinolone in the scar immediately after laser treatment; the traditional injection group was injected with triamcinolone in the scar.The gross appearance of hypertrophic scars was observed and recorded in 4 groups. At 7 days and 2 months after treatment, the hypertrophic scars were cut and the histological study were performed by HE staining; the expression of collagen was observed by Masson staining and the volume fraction of collagen was measured; the number of micro-vessels was observed by CD31 staining and the micro-vessel density was measured.One way ANOVA was used to show the difference between groups, LSD posthoc test was used to compare between groups, and Pearson correlation coefficient was used to analyze collagen volume fraction and micro-vessel density.Results:Two months after the treatment, the histological results showed that the scar thickness of the laser combined group and the laser combined with multi-point microinjection group was significantly thinner than that of the control group, the texture of the scar was softened, the red color gradually became lighter, and approached to the color of the surrounding skin. Compared with the control group, the scar in the traditional injection group was thinner, softer and lighter. The scar thickness of laser combined with multi-point microinjection group was thinner than that of laser combined group and simple traditional injection group.Masson staining was used to calculate the collagen volume fraction (CVF): the expression of CVF in hypertrophic scar tissue of each group was reduced. The CVF values of each group at the 7th day and the 2nd month were compared. There was statistically significant difference between the laser combined group, the laser combined multi-point microinjection group and the simple traditional injection group ( P<0.05), but there was no statistical difference between the control group ( P>0.05). The CVF value of each group was further compared at 2 months after treatment, the laser combined multi-point microinjection group 0.05). 2 months after treatment, the MVD values of each group were compared with the result as the laser combined with multi-point microinjection group < laser combined group < simple traditional injection group, but there was no statistical difference between the laser combined with multi-point microinjection group and the laser combined group ( P>0.05). There was statistical difference between the laser combined with multi-point microinjection group and the laser combined group and the simple traditional injection group ( P< 0.05). The Pearson correlation coefficient was r=0.972, which indicated that there was a positive correlation between the collagen content and the number of micro-vessels. Conclusions:The use of fractional laser combined with pulsed dye laser and multi-point microinjection of triamcinolone in the treatment of hypertrophic scars in rabbit ears can evenly reduce the number of fibroblasts, promote the normalization of collagen density and arrangement, and reduce collagen volume fraction and micro-vessel density. The curative effect is better than fractional laser combined with pulse dye laser therapy and simple traditional triamcinolone injection therapy. There is a positive correlation between collagen content and micro-vessel density in hypertrophic scars. Simultaneously inhibiting the proliferating blood vessels can improve the therapeutic effectiveness.
