Hypocalcemia often exists in critical illness children. Most of the sick children do not have an underlying disease of calcium homeostasis, and the mechanism of the hypocalcemia is complicated. Abnormal values of blood calcium may be a sign of critical illness and normalize spontaneously with resolution of the primary disease process. Hypocalcemia may be a autoprotection , and it may be harmful if we try to correct it. This article focuses on the theory and clinical treatment of hypocalcemia in critical illness children.

OBJECTIVE: To investigate the statistical method of tri-allelic patterns of STR loci. METHODS: The DNAs of venous blood and blood stain samples from 8,846 unrelated individuals were extracted using magnetic bead method, and STR genotypes were determined by multiplex fluorescent amplification and capillary electrophoresis and analyzed using GeneMapper ID v3.2 software. The genotype frequency and allele frequency of trizonal were determined by direct counting and formula, respectively, in order to deduce the formula of trizonal in paternity test and individual recognition. RESULTS: Of the 8,846 individuals, four tri-alleles and three tri-genotypes were detected. The multiplying of allele frequency and actual rate showed significantly statistical difference. The formula of trizonal in paternity test and individual recognition was successfully deduced. CONCLUSION The frequency of the two alleles inherited as a whole in the population could be calculated by multiplying the frequencies of each allele in the tri-allelic patterns.

Remote ischemic postconditioning can induce cerebral ischemic tolerance and have neuroprotective effects.It has provided a novel strategy for the treatment of ischemic cerebrovascular disease.In recent years,the mechanism research of remote ischemic postconditioning and clinical applications have made significant progress and have shown encouraging prospects of clinical transformation.

Dipeptydil-peptidase-4 (DPP-4) inhibitors are designed as oral anti-hyperglycemic drugs for the treatment of type 2 diabetes owing to their effects on the incretin system through sparing incretin hormones including glucagon-like peptide-1 (GLP-1) from rapid degradation by DPP-4.It has been shown that GLP-1 signaling may exert beneficial effects on cardiovascular system.In addition to GLP-1,DPP-4 physiologically cleaves cytokines,chemokines,and neuropeptides involved in inflammation,immunity,and vascular function.It means that DPP-4 inhibitors hold promise for cardiovascular protection independent of GLP-1.And its modulation of endothelial progenitor cells,infiammatory pathway,ischemic response,and lipid metabolism emerges as the major cardiovascular target of DPP-4 inhibitors.

Objective To investigate the changes of the peripheral blood platelet counting and function the mouse model of idiopathic thrombocytopenic purpura (ITP) and to observe the effect of Zidian Granule (ZG). Methods The peripheral platelet counting was conducted with the automatic hemocyte analyzer; CD41 andCD61 level was measured with flow cytometry. Results The amount of the peripheral blood platelet in ITP model mouse was decreased after injection of antiplatelet serum (APS) and CD41 and CD61 were also decreased.(P

Objective To determine the quality of life of patients treated with one of three different types of surgery for breast cancer.Methods This was a cross-sectional study using a questionnaire survey completed by Chinese patients without active disease after at least 2 years of follow-up after breast cancer surgery.Results This study totally included 139 breast cancer patients:44 ( 31.6%) had undergone modified radical mastectomy with reconstruction, 41(29.5%)had a quadrantectomy with axillary lymph node dissection, and 54(38.9%)had a modified radical mastectomy without reconstruction.The EORTC QLQ-C30 and EORTC QLQ-BR23 question-naires were used;their reliability was>0.82.Global health status(94.30 ±12.04, P=0.028)and role functio-ning(85.16 ±17.23, P=0.138)were highest in the quadrantectomy group.Pain score was highest in the modi-fied radical mastectomy with reconstruction group(26.13 ±30.15, P =0.042).The breast symptom score (22.56 ±22.30, P=0.009)and body image perception(85.56 ±19.72, P=0.025)were highest in the conser-vative treatment group.The overall health of patients given modified radical mastectomy without reconstruction was lower(72.61 ±20.89, P=0.014) in women older than 50 years compared with younger women.Conclu-sions The quadrantectomy with axillary lymph node dissection procedure had better acceptance, but the overall health status did not differ between groups.Overall health status is lower in women older than 50 years receiving a modified radical mastectomy without reconstruction.

ObjectiveTo explore the characteristics of neuro-electrophysiology and clinical value in patients with Guillain-Barre syndrome.MethedsWe performed retrospective analysis of the clinical date of 46 patients with Guillain-Barre syndrome in our hospital.Hughes grades and neuro-electrophysiological measure including motor conduction velocity (MCV),complex muscle action potential (CMAP),sensory conduction velocity (SCV) and F wave,were investigated as the related factors with the prognosis of GBS.Results The rate of abnormal F wave was higher than the rate of abnormal MCV.The rate of abnormal SCV was lower than the rate of abnormal F wave and MCV( P ＜0.05).The prognosis of the acute inflammatory demyelinating polyneuropathy (AIDP) group was superior to the acute motor axonal neuropathy (AMAN) group,and there had significant difference( P ＜0.05).ConclusionsThe neuro-electrophysiological investigation is an important way to diagnose the GBS.F wave is a sensitive and specify index in the early diagnosis of GBS.The neuro-electrophysiological observation of MCV and CMAP may be served as cues for diagnosis,determination of the subtype and evaluation of the treatment effect in GBS.

Progestagen-associated endometrial protein (PAEP) gene mainly expresses in the secretory phase endometrium and decidua in early trimester of pregnancy.In recent years,it is reported that PAEP is abnormally expressed in many kinds of tumors,such as breast cancer,endometrial carcinoma,ovary cancer,stomach cancer and melanoma.PAEP gene plays an important role in tumorigenesis and tumor development.The application of PAEP gene as an indicator for clinical diagnosis,prognostic and therapy needs further studies on the influence of PAEP gene on tumor biological behaviour.

Objective To compare clinical-pathological features and Ki-67 expression profile between TNBC and Non-triple-negative cancer (NTNBC). Methods The expressions of ER, PR and HER2 were examined by immunohisto?chemical Envision double staining in 226 cases of breast cancer. All cases were divided into triple-negative and non-triple-negative group according to expressions of these three episodes. And Ki-67 expressions in two groups were assessed by im?munohistochemical method. The difference of Ki-67 positive index between these two groups and the difference of Ki-67 positive index between different clinical-pathological features were both analyzed by comparative analysis. Results In pa?tients with TNBC, tumor size, lymph node metastasis rate and Ki-67 index were all significantly higher than that in NTNBC. No significant difference in age and histological grade were detected between these two groups. The expression of Ki-67 was not significant correlated with age, tumor size,lymph node status and histological grade in these two groups. Conclusion Patients with triple-negative breast cancer were with larger tumor size, higher proliferation, more lymph node metastasis and poorer prognosis.

Objective To observe the therapeutic effect of the method of soothing liver qi stagnation and invigorating blood circula- tion to remove stasis for depression.Methods Totally 90 depression cases were randomized into treatment group and control group with 45 in each.The treatment group was given modified Xiaoyao Powder(Powder for liver qi stagnation with blood stasis) based on the principle of soothing liver qi stagnation to remove stasis.The control group was given Fluoxetine.The course of treatment was 8 weeks in all.Self-rating Depression Scale(SDS),Hamilton Depression Scale(HAMD),Treatment Emergent Symptom Scale (TESS) and scores of TCM symptoms before and after treatment were recorded for comparison.Results SDS,HAMD,TESS and TCM symptoms were improved after treatment in the treatment group(P
