Objective: To observe the effect of yoghurt supplementation on the growth rate of preschool children in Beijing suburb. Methods: 402 healthy children (217 males, 185 females), aged 3-5 years old, were selected as subjects with height and/or weight less than WHO standard from 7 kindergartens in Beijing suburb. The children were divided randomly into control group (CG 201) and yoghurt supplemented group (YG 201). Children in YG were supplemented with yoghurt (125g) for 5d per week for 9 mo, and children in CG not supplemented. Height, weight and upper-arm circumference were measured every month. Blood biochemical parameters (Hb,TP) were detected every 3 mo. Results: Calcium, zinc and VB2 were consumed more in YG than CG. Hb in YG was also higher than CG . The height incease and weight gain of YG was significantly higher than CG during 3, 6 and 9mo. Conclusion: Yoghurt supplementation for 9 months can increase calcium, zinc and VB2 intake, and improve preschool childrens nutritional status, therefore increase their height increase and weight gain.

Objective To explore the feasibility and effect of laparoscopic Ladd's surgery for the treatment of intestinal malrotation in infants.Methods The clinical data of 50 infants with intestinal malrotation who were admitted to the Wuhan Medical & Health Center for Women and Children from January 2011 to December 2013 were retrospectively analyzed.Of 50 infants, 27 infants receiving the open Ladd's surgery were allocated into the open surgery group and 23 infants receiving the laparoscopic Ladd's surgery were allocated into the laparoscopy group.The operation time, time to anal exsufflation, duration of hospital stay, postoperative incision infection and intestinal obstruction in the 2 groups were observed.All the patients were followed up by outpatient examination or telephone interview till March 2014.The measurement data with normal distribution were presented as x-± s and analyzed by the t test, and count data were analyzed using the chi-square test or Fisher exact probability.Results The operation time, time to anal exsufflation and duration of hospital stay were (69 ± 7)minutes, (41 ±9)hours and (10.4 ± 2.4)days in the open surgery group, which was significantly different from (92 ± 13)minutes, (28 ±5)hours and (6.4 ± 1.5) days in the laparoscopy group (t =6.21, 16.50, 6.34,P ＜ 0.05).Two infants had incision infection and 1 infant had intestinal obstruction in the open surgery group.There was no patient with complications in the laparoscopy group.All the patients were followed up for the median time of 13 months (range, 6-24 months), with a good survival and no other symptoms.Conclusion Laparoscopic Ladd's surgery is safe and feasible compared with open surgery, and it could be used as a prior operation method for treatment of intestinal malrotation in infants.

Objective: To explore the changes of the peripheral invariant natural killer T (iNKT) cells in patients with human immunodeficiency virus (HIV) infection. Methods: A total of 101 patients with HIV infection including 52 asymptomatic patients and 49 acquired immunodeficiency syndrome (AIDS) patients were enrolled in the study from June 2016 to July 2017. Flow cytometry was used to detect iNKT cells, CD4⁺ T cells and CD8⁺ T cells, and the relationship among them and HIV RNA was studied. At same time, 12 healthy persons were enrolled as control group. T test or variance analysis, rank sum test, Chi-square test and Fisher exact test were used for statistical analysis. Results: In HIV infected asymptomatic patients, AIDS patients and healthy controls, iNKT cells were 0.135% (0.066%, 0.228%), 0.058% (0.034%, 0.100%) and 0.385% (0.205%, 0.600%), respectively, and the difference was statistical significant (Z=40.113, P<0.01). CD4⁺ T cell counts in the three groups were (340.82±119.26) cells/μL, (72.73±61.84) cells/μL and (555.17±229.43) cells/μL, respectively, and the difference was statistical significant (t=113.79, P<0.01); CD8⁺ T cell counts in the three groups were (842.29±423.68) cells/μL, (540.43±257.85) cells/μL and (875.92±516.45) cells/μL, respectively, and the difference was statistical significant (t=9.423, P<0.01). Ratios of CD4⁺ /CD8⁺ T cells in the three groups were 0.490 (0.240, 0.695), 0.120 (0.030, 0.210) and 0.600 (0.475, 0.895), respectively, and the difference was statistical significant (Z=53.603, P<0.01). iNKT cell counts in patients with or without hepatitis B virus infection, pneumocystis pneumonia, oral mold infection, treponema pallidum, latent tuberculosis or EB virus infection were not significantly different (Z=0.244, 2.325, 2.393, 0.168, 1.183 and 0.454, respectively, all P>0.05). There were correlations between iNKT cells and CD4⁺ T cells, CD4⁺ /CD8⁺ T cells (r=0.513 and 0.261, respectively, both P<0.05), and no relationship was found between iNKT cells and CD8⁺ T cells (r=0.155, P=0.126). In HIV infected asymptomatic patients and AIDS patients, iNKT cells was not associated with HIV RNA (r=-0.113 and -0.111, respectively, both P>0.05). Conclusions The level of peripheral iNKT cells in HIV infected patients decreases with the disease progression. To certain extent, iNKT cells can reflect the severity of immune damaging in HIV infected patients.
