Objective To evaluate the accuracy of the soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) and lipopolysaccharide binding protein (LBP) as diagnostic indices for neonatal serious bacterial infections (SBI). Methods A total of 171 newborns were enrolled in the study, and were classiifed into SBI group (including early-onset and late-onset), non-SBI group according to clinical manifestations, laboratory examinations and the time of disease onset. Serum sTREM-1, LBP and C-reactive protein (CRP) levels were measured. Receiver operator characteristic curve (ROC) was drawn, and the area under curve (AUC) was calculated. Each index was evaluated for the diagnostic value of neonatal SBI. Results The sTREM-1 and LBP levels were signiifcantly higher in SBI group than those in non-SBI group (P=0.000). The AUC of ROC for sTREM-1, LBP and CRP in early-onset SBI was 0.888, 0.839 and 0.706, respectively. The AUC of ROC for sTREM-1, LBP and CRP in late-onset SBI was 0.860, 0.865 and 0.705, respectively. Conclusions Both sTREM-1 and LBP are useful for the diag-nosis of neonatal SBI.

Objective To investigate the clinical effect of flupentixol and melitracen tablets combined with macrogol 4000 powders on treatment of irritable bowel syndrome with constipation (IBS-C) in elderly patients. Methods Fifty paients aged from 65 to 95 years with IBS-C were randomly divided into 2 groups: control group (23 patients) and treatment group (27 patients). The patients in treatment group received flupentixol and melitracen tablets (1 tablets, once a day) combined with macrogol 4000 powders (1 bag/time, 2 times a day) , while the patients in control group received macrogol 4000 powders alone. The treatment period was 4 weeks. The curative effect, the scores of self-rating depression scale (SDS) and self-rating anxiety scale (SAS) and adverse reaction were compared between two groups.

At the improvement of anxiety symptoms, the effective rate in treatment group and control group was 74.1%(20/27) and 26.1%(6/23), and there was significant difference (P<0.01). The total effective rate in treatment group and control group was 88.9%(24/27) and 65.2%(15/24), and there was significant difference (P<0.05). Conclusions Flupentixol and melitracen tablets combined with macrogol 4000 powders on treatment of aged IBS-C patients have more distinguished therapeutic effect in improving constipation symptoms, stools times, anxiety and depression.

Objective To study metabolism of glucose and lipidin patients with hyperandrogenism and analyze the risk of their cardiovascular disease.Methods Object of study:firstly,choosed 118 cases of women of reproductive age from April 2013 to July 2014.Then detected their serum Testosterone (T),Estradiol (E2),fasting plasma Glucose (FPG),fasting plasma insu-lin (FINS),triglycerides (TG),total cholesterol (TC),high-density lipoprotein cholesterol (HDL-C),low-density lipopro-tein cholesterol (LDL-C),lipoprotein (a),body mass index (BMI).Finally,divided them into different groups and analyzed the results using SOSS19.0 software and two independent samples t-test statistical method.Results BMI,T,FPG,HOMA-IR and TG were significantly more higher (P <0.05)in the group of hyperandr-ogenism than in the group of normal con-trol.However,E2,TC,HDL-C,LDL-C and LP(a)had no significant difference (P >0.05)in statistics between the group of hyperandrogenism and the group of normal control.Hyperandr-ogenism group was divided into PCOS group and non-PCOS group according to etiology.In those two groups,BMI,T,E2,FPG,HOMA-IR,TG,TC,HDL-C,LDL-C and LP(a)had no significant difference in statistics (P >0.05).According to the definition of obesity adults in china,78 patients with hyperan-drogenism were divided into 2 group,one with BMI normal (BMI<24 kg/m2 )and the other group with overweight and obe-sity (BMI≥24 kg/m2 ).In group with overweight and obesity,BMI,T,FPG,HOMA-IR,TG,TC,LDL-C and LP (a)were significantly higher than the group with BMI normal (P <0.05),moreover,HDL-C was significantly lower than the group normal (P <0.05).E2 had no significant difference in statistics between the two groups (P >0.05).Conclusion Investiga-tion of the relation between hyp-erandrogenism and metabolism of glucose and lipid,can not only practically guide life style and drug therapy,but also prevent cardio-vascular disease.

BACKGROUND:The appropriate choice of orthoses based on hemiplegic patient’s condition can improve motor function recovery in stroke patients.
OBJECTIVE:To review the motor function recovery of stroke patients with hemiplegia wearing different types of orthoses.
METHODS:Application of different types of orthoses in hemiplegic patients was reviewed through access to literature, as wel as effects of a variety of orthoses on the recovery of motor functions in hemiplegic patients.
RESULTS AND CONCLUSION:Orthoses can reduce limb muscle tension and muscle spasms, and improve motor function and overal daily living skil s in stroke patients with hemiplegia, which play a variety of roles, including stable support, fixed protection, correction of deformity and functional compensation. However, the long-term therapeutic effect of orthoses cannot be verified because of fewer cases, shorter time for therapeutic observation, and the lack of long-term fol ow-up. It is necessary to perform long-term fol ow-up for the verification of long-term efficacy of orthoses. Meanwhile, the appropriate timing for removal of orthoses needs further study.

BACKGROUND:Stem cells under appropriate conditions can be induced to differentiate into neuron-like cells. Chinese herbs can function in cellproliferation and differentiation.
OBJECTIVE:To investigate the interventional effects of traditional Chinese medicine on stem celltransplantation in the treatment of cerebrovascular diseases.
METHODS:Experimental studies concerning traditional Chinese medicine intervention for stem celltransplantation were retrieved and analyzed. Under specific conditions, stem cells can proliferate in vitro in a suspended or monolayer manner, and can be potential y induced to differentiate into neurons, oligodendrocytes and astrocytes, thereby providing basis for stem celltransplantation in the treatment of cerebrovascular diseases. We observed expressions of nestin, glial fibril ary acidic protein, and microtubule-associated protein expression for analysis of stem cellproliferation and differentiation.
RESULTS AND CONCLUSION:Baicalin or Astragalus saponin Ⅳ can stimulate stem cells to differentiate into nerve cells in vitro. Naomaitong or danshen combined with bone marrow mesenchymal stem celltransplantation can promote neurological recovery from cerebrovascular diseases in rats. Buyang Huanwu Decoction can significantly promote the proliferation of neural stem cells in the subventricular zone and neurological recovery after cerebral ischemia. Chinese herbs, such as Zhichan Decoction and Panax notoginseng, can promote survival of transplanted cells and prevent most cellapoptosis in the stem celltherapy for treatment of Parkinson’s disease. Therapy of benefiting qi and elevating yang or ginsenosides Rg1 combined with stem celltherapy can improve memory ability of dementia rats. Traditional Chinese medicine exerts a catalytic role in the stem celltherapy for cerebrovascular diseases.
