Objective To explore the changes of T-lymphocyte subsets,D-Dimer and immunoglobulin in mycoplasma pneumonia children and its significance.Methods The levels of T lymphocyte subsets (CD3 +、CD4 +、CD8 +、CD4 +/CD8 +)in 50 children with mycoplasma pneumonia (MPP Group)and 50 healthy children were detected by flow cytometry;The levels of D-Dimer were detected by immunoturbidimetry;The levels of serum immunoglobulin were detected by immune turbidimetric method.Results The results of T lymphocyte subsets:Compared with normal control group, CD3 +and CD4 +peripheral blood cells in MPP group were significantly declined(P<0.001)、CD8 +cells were increased slightly,but with no significant difference、CD4 +/CD8 +ratios were decreased slightly.The results of D-Dimer:Compared with normal control group,the levels of D-Dimer in MPP group were significantly escalated(P<0.001).The results of immunoglobulin:IgA and IgMin MPP group were both significantly higher than those of normal group,but IgG was not different from that in normal group.Conclusion Children with mycoplasma pneumonia have immune disorder,which may generate abnormal clotting.Therefore,besides the conventional anti-mycoplasma pneumonia treatment,we need to detect the levels of D-Dimer according to the clinical symptoms and disease progression and strength the regulation and treatment of the immune system.

Objective:To observe the clinical effect of tuina combine with needling distal points for pseudo-myopia in adolescents. Methods:A total of 64 adolescents with pseudo-myopia were allocated into a treatment group and a control group by the random number table, 32 cases in each group (64 eyes). Cases in the treatment group were treated with tuina combined with needling distal points, whereas cases in the control group were treated with the same tuina method (manipulations, treatment area and time) as those in the treatment group. The treatment was done once a day for 10 d as a treatment course. They were treated for 3 courses and there was a 2-day interval between two courses. After 3 treatment courses, all cases were re-examined for the short-term effect on uncorrected eyesight using the logarithmic visual acuity chart and on diopter using retinophotoscopy. Results:After 3 treatment courses, the visual acuity in both groups was improved. The total effective rate was 92.2% in the treatment group, versus 82.8% in the control group, showing a statistical significance (P<0.05) and indicating a better effect in the treatment group than that in the control group. Conclusion:Tuina combined with needling distal points is remarkably effective for pseudo-myopia in adolescents. Since it doesn’t cause fear (from needling local points around the eyes), it’s easy to be accepted by adolescents and worthy of further clinical application.

Objective To study the T Lymphocyte Subsets and the cytokines in the newborns with infectious diseases. Methods Twenty cases of neonatal bacterial pneumonia (bacterial group), 15 cases of rotavirus enteritis (virus group) and 20 newborns with jaundice (control group) were recruited in this study. The peripheral CD4+T Cells and lymphocyte subsets were assessed by flow cytometry. Results The IL-4 level was significantly different among different groups (F=3.39, P=0.041). The levels of IL-17 and IFN-γdid not differ signiifcantly among different groups (F=0.28 and 1.24 respectively, P>0.05). The IL-4 level was higher in bacterial group than that in virus group and control group (P<0.05). The percentages of CD3+, CD4+, CD19+and NK cells and the ratio of CD4+/CD8+ had significant difference among different groups (F=3.30-26.69, P<0.05). The percentages of CD3+and CD4+cells and the ratio of CD4+/CD8+were lower in bacterial group and virus group than those in control group (P<0.05). The percentage of CD19+cells was higher in bacterial group and virus group than that in control group (P<0.05). The percentage of NK cells was lower in virus group than that in bacterial group and control group (P<0.05). Conclusions The pattern of cytokines level is different in newborns with infection caused by different pathogens. Newborns with infectious diseases have immune dysfunction and Th2-dominated imbalance. The low percentages of T lymphocyte subsets indicate the depressed cellular immunity after infection, which may result in atypical symptom and prolonged disease course.

Objective The purpose of this study was to evaluate the feasibility of expiratory flow limitation(EFL) detected by negative(NEP) and the correlation between EFL and routine lung function measurements(Forced expiratory volume in first second,FEV1),EFL and MRC dyspnea scale,in patients with stable and acute asthma,to find a simple,reliable and objective method for the diagnosis,differential diagnosis,the severity of disease and evaluation of severity and efficacy of treatment for asthma,and a objective method reflecting the severity of dyspnea.Methods Sixty-four children enrolled in No.306 Hospital of PLA from Jun.to Dec.in 2012 were included in this study.The severity of dyspnea was rated according to the dyspnea scale proposed by the Medical Research Council(MRC).Then routine pulmonary ventilation function tests and NEP technique were performed respectively.Result (1) All asthmatic patients tolerated NEP well.(2) Pulmonary ventilation function tests:The mean FEV1 in 64 was 71.33 ± 13.92％ pred.(3) MRC dyspnea scale:MRC dyspnea scale was 2 in 10,1 in 54 of 64 children with stable asthma.The Spearman' s correlation coefficient of MRC dyspnea scale with FEV1 was-0.635(P ＜0.05).(4)EFL detected by NEP:There were no EFL in 46 children with asthma both in seated and supine positions.There were EFL in 8 children both in seated and supine positions and in 10 only in supine position..The Spearman's correlation coefficient of three-point EFL score with FEV1 and MRC dyspnea scale was-0.607 and 0.964(P ＜ 0.05) respectively.The Spearman's correlation coefficient of five-point EFL score with FEV1 and MRC dyspnea scale was-0.626 and 0.966 (P ＜ 0.05)respectively.Conclusion (1) NEP technique can be used in children with asthma.(2) There was a significant correlation between EFL detected by NEP technique and FEV1.(3) There is a stronger correlation between EFL and MRC dyspnea scale than that between FEV1 and MRC dyspnea scale.

Children′s unique physiological, developmental and psychological attributes make them one of the most vulnerable groups in large-scale flood disasters.Formulating a reasonable and feasible emergency preparedness plan for flood disasters can improve their ability to cope with flood disasters and optimize the outcomes of children suffering from flood disasters.The emergency preparedness plan for children′s flood disaster should cover the allocation and utilization of various resources during disasters, regional cooperative rescue and evacuation of children, ethical problems in treatment under special circumstances, psychological counseling of children, family members and medical personnel.Relevant staff of pediatric emergency rescue need to consider all aspects and make reasonable plans so that the rescue work of children affected by disasters can be carried out in an orderly manner.

Objective To discuss the clinical application of laparoscopic ultrasound (LUS) in laparoscopic nephron sparing surgery(NSS) for central renal tumors.Methods Eighteen patients underwent laparoscopic NSS for central renal tumors.The use of LUS was mainly lay in observing the nature and size of the tumor, the minimum distance from the tumor to capsule, collective system and renal artery, tumor's vasa vasorum,tumor localization and determination of margins.Results Of the 18 central renal tumors,the size was 11 - 29 mm,23.3 mm in average.The minimum distance from the tumor to capsule was 2 - 11mm,4.7 mm in average.The minimum distance within 5 mm to collective system and to capsule was 12 and 10 cases respectively.The tumor was surrounded by nephridial tissue completely on LUS, without protruding capsule.LUS diagnosis of 18 central renal tumors: 10 cases of renal angiomyolipoma,7 cases of renal cell carcinoma, 1 case of renal cyst with capsule wall calcification (at first diagnosed as renal carcinoma by CT).The findings of LUS were same to pathologic and(or) postoperative diagnoses.The accuracy of ultrasound localization was 100％.The surgical margins of 7 cases of renal cell carcinoma were all negative.Conclusions It is of high clinical value of LUS on locating the tumor and defining tumor margins in laparoscopic resection of central renal tumors.Besides, more information on tumor and vessel supply will be achieved.

Objective To investigate the correlation of previous hepatitis B virus (HBV) infection with the incidence risk of chronic pancreatitis (CP).Methods This was a case control study.Five hundred and seventy-one patients with CP admitted in the Department of Gastroenterology, Changhai Hospital, Second Military Medical University between January 2015 and October 2016 were enrolled, and 1216 sex and age matched health individuals were also enrolled as the control group.The 5 serum HBV markers(HBsAg,HBsAb, HBeAg, HBeAb and HBcAb) were detected and their correlation with CP incidence was analyzed.Results The positive rate of HBsAg in the CP group and the control group were 3.0% and 3.8%, respectively, and the difference was statistical significant.(OR=0.039, 95% CI 0.02~0.80, P<0.00), but in all the HBsAg positive models (HBVM) the difference of CP and control groups was not statistical significant.HBsAb positive rate in CP group and the control group were 51.8% and 75.0%, respectively, and the difference was statistical significant(P<0.000).HBeAg positive rate in CP group and the control group were 1.1% and 0.1%, the difference was statistical significant (P<0.05), but in all the HBeAg positive models, the CP group and the control group had no statistical difference (P>0.05).The positive rate of HBeAb in the CP group and the control group were 24.3% and 10.8%, respectively, and the difference was statistical significant(P<0.00).The positive rate of HBcAb in the CP group and the control group were 50.1% and 16.5%, respectively,and the difference was statistical significant(P<0.000).In the(HBsAb+, HBeAb+, HBcAb+), (HBsAb+, HBcAb+), (HBeAb+, HBcAb+), (HBcAb+) models, the positive rate in CP group was significantly higher than that of the control group(P<0.000).Multivariate regression analysis showed that the positivity of HBsAb and HBeAb were the protection factors for the occurrence of CP(P<0.05),and HBcAb positivity was the independent risk factor for CP (OR=6.931,P<0.000).Conclusions HBsAb and HBeAb poitivity were the protectors for CP, while HBcAb positivity could be considered as an independent risk factor for CP.

ObjectiveTo study effects of treating acute progressive cerebral infarction by the brain-located mild hypothermia therapy.Methods60 patients were randomly divided into the treatment group (30 cases) and the control group (30 cases). Drugs were used in both groups, and the located mild hypothermia therapy was only applied in the treatment group. After 72 hours and 7 days, the volume of cerebral infarction and the nerve function deficiency (NFD) scores of hemiplegic limbs were compared.ResultsThe volume of cerebral infarction of the treatment group was significantly smaller than that of the control group (P<0.01).There were significant differences on the neurological impairment scores between two groups (P<0.01).Conclusions The brain-located mild hypothermia therapy can reduce hydrocephalus of patients with acute progressive cerebral infarction, and have brain protection. These results provide an important theoretical foundation for the treatment of cerebral infraction with low-temperature therapy.
