Objective To evaluate the value of minimally invasive technique in treatment of severe traumatic intracranial hematoma at emergency department.Method From January 1995 to December 2005,126 patients were treated by using the minimally invasive technique in Affiliated Chaoyang hospital once patients were diagnosedas severe traumatic cerebral hernia resulted from intracranial hematoma and also those whose clinical data were retrospectively analyzed.In the emergency department,the per-operative plan was done according to the CT imaging,including the sute of burr hole on the skull,the direction and depth of carmulation,and the drainage cannula was put into the hematoma cavity for external drainage under local anesthesia.Results The successful rate of puncture was 100%.The patients's dukated oyouk contracted immediately after drainage.There are 79/ 95 patients(83.1%)had single pupil dilated and 17/31(54.8%)patients had bilateral pupils dilated.The immediately clinical effective was 76.2%.According to Glasgow outcome scale,43 of 126 patients had good recovery,26 had moderate deficits and 18 had severe sequelae,16 patients were in vegetative state,18 died. Conclusions Clinical prospective study proves that minimally invasive technique can ameliorate the cerebral hernia,prolong the operative therapie window time.

Acute respiratory distress syndrome (ARDS) is a common clinical critical disease, characterized by progressive respiratory distress, intractable hypoxemia, respiratory failure and so on, with high mortality rate and lack of effective prevention and treatment strategies. In recent years, mesenchymal stem cell (MSC) can be used in the treatment of acute lung injury (ALI), which cannot only replace the damaged lung epithelial cells, but also promote tissue repair and alleviate ARDS by secreting anti-inflammatory and anti-fibrosis factors. This review focuses on the related mechanisms and signal pathways of MSC and its paracrine factors in the treatment of ARDS by regulating the balance of macrophage polarization.

OBJECTIVETo investigate the relationship between the second to the fourth digit ratio (2D:4D) and body mass index (BMI) in infertile men of the Han ethnic group in Ningxia.

METHODSUsing anthropometry, we calculated the mean ratio of 2D:4D and BMI of 197 infertile men and 148 normal healthy male controls, followed by analysis of their relationship.

RESULTSThe BMI was correlated positively with the 2D:4D ratio of the left hand in the infertile men (P < 0.05) and in the patients with a higher 2D:4D ratio of the left hand (P < 0.05), but negatively with the 2D:4D ratio of the righ/left (Dr-1) (left: P < 0.01; Dr-l: P < 0.05). The mean 2D: 4D ratio and BMI were both lower in the normal control than in the infertile men, with statistically significant differences in BMI (P < 0.05) and the 2D:4D ratio of the left hand (P < 0.05).

CONCLUSIONThere is a correlation between the 2D:4D ratio and BMI in infertile men.

OBJECTIVETo discuss the clinical effects of external fixator combined with limited internal fixation in the treatment of pediatric distal femur fractures.

METHODSFrom January 2008 to June 2014, 17 children of distal femur fractures were treated by external fixator combined with limited internal fixation. There were 12 males and 5 females, aged from 6 to 13 years old with an average of 10.2 years, ranged in the course of disease from 1 h to 2 d. Preoperative diagnoses were confirmed by X-ray films in all children. There were 11 patients with supracondylar fracture , and 6 patients with intercondylar comminuted fracture. According to AO/ASIF classification, 9 fractures were type A1, 5 cases were type A2,and 3 cases were type C1. The intraoperative and postoperative complications, postoperative radiological examination, lower limbs length and motion of knee joints were observed. Knee joint function was assessed by KSS score.

RESULTSAll the patients were followed up from 6 to 38 months with an average of 24.4 months. No nerve or blood vessel injury was found. One case complicated with the external fixation loosening, 2 cases with the infection of pin hole and 3 cases with the leg length discrepancy. Knee joint mobility and length measurement (compared with the contralateral), the average limited inflexion was 10 degrees (0 degrees to 20 degrees), the average limited straight was 4 degrees (0 degrees to 10), the average varus or valgus angle was 3 degrees (0 degrees to 5 degrees). KSS of the injured side was (96.4 +/- 5.0) points at final follow-up, 16 cases got excellent results and 1 good. All fractures obtained healing and no epiphyseal closed early was found.

CONCLUSIONExternal fixator combined with limited internal fixation has advantages of simple operation, reliable fixation, early functional exercise in treating pediatric distal femurs fractures.

OBJECTIVETo investigate the clinical effect of chronic myelocytic leukemia (CML) patients treated with imatinib (IM) and interferon (IFN)-α.

METHODSOne hundred and fifty five CML patients at chronic phase were included in the study. All patients were divided into two groups according to treatment regimen: IM + IFN group and IM group. Complete cytogenetic response (CCyR) rate, major molecular response (MMR) rate, complete molecular response (CMR) rate, overall survival (OS) and progression free survival (PFS) were observed and compared in both groups.

RESULTSThe CCyR rate was higher in the IM + IFN group than that in the IM group at 6 months (60.6% vs 41.6%, P < 0.05), but no difference was observed later on. The MMR + CMR rate was higher in the IM + IFN group than that in the IM group at 6 months and 12 months (71.2% vs 34.8%, 77.3% vs 52.8%, respectively, P < 0.05), but no difference after that. After stratification according to Sokal risk, the CCyR rate of low- and intermediate-risk patients was higher in the IM + IFN group than that in the IM group at 6 months (77.8% vs 52.6%, 75.0% vs 46.7%, P < 0.05), but not from 12 months on; the MMR + CMR rate of low- and intermediate-risk patients was higher in the IM + IFN group than that in the IM group at 6 months and 12 months (85.2% vs 36.8%, 90.0% vs 36.7%, P < 0.05; 88.9% vs 57.9%, 90.0% vs 56.7%, P < 0.05), but not from 24 months on. There was no significant difference in high-risk patients. OS in IM and IM + IFN group at 6, 12, 24 and 36 months was 100%, 100%, 96.8% and 90.0%, and 100%, 100%, 97.9% and 93.1%, respectively. PFS in IM and IM + IFN group at 6, 12, 24 and 36 months was 97.8%, 95.5%, 91.9% and 85.5%, and 98.5%, 95.5%, 91.5% and 86.2%, respectively. There was no significant difference in OS (u = 0.427, P = 0.514) or PFS (u = 0.556, P = 0.456). The side effects in both groups included pancytopenia, edema, weight gain, ostalgia, rash and muscle spasm. In addition, patients in the IM + IFN group suffered from flu-like symptoms, impaired liver function, abnormal thyroid function and extremity sensory disturbance. It seemed that grade III or IV pancytopenia occurred more commonly in the patients in the IM + IFN group, however, there was no statistically significance.

CONCLUSIONSThe response to IM + IFN is more rapid than that to IM alone, especially for the low- and intermediate-risk patients. It seems no benefit of the addition of IFN to treatment of high-risk patients. During the period of 36 months, survival rate in the IM + IFN group is not higher than that in IM group, and it is possible to increase the side effects of pharmaceutical drugs.

A method was proposed for the separation and determination of paraffin waxes in food by HPLC-evaporative light scattering detection (ELSD). A normal-phase column was used to separate nonparaffinic and paraffinic materials without resolving the latter into individual components. The t-test method was adopted for the evaluation of mean difference between response factors of n-alkanes in paraffin waxes on ELSD detector. No mean difference was obtained between response factors, which can be used for quantitative determination of paraffin waxes in food. The determination results obtained by HPLC-ELSD were compared with those by GC-MS. The linear range for the determination of paraffin waxes was in the range from 10 to 500 mg/L with a correlation coefficient of 0.9988, and the limit of detection was 1.0 mg/L. With the spiking level of 10, 50 and 100 mg/kg, the recovery ranged from 84.6% to 105.4% and the relative standard deviation ranging from 5.4% to 7.2%. The proposed method is simple, fast and sensitive.

Objective To investigate the expression and distribution of plasmacytoid dendritic cells(pDC) in peripheral blood and renal tissues in children with Henoch-SchSnlein purpura(HSP),and explore the role of pDCs in the pathogenesis of Henoch-Schtnlein purpura nephritis(HSPN).Methods Among the 40 children with HSP,28 cases were in the active phase(renal biopsy performed in 8 cases of them) and the other 12 in remission phase.Peripheral blood mononuclear cells were isolated,and the expression of pDC was detected by flow cytometry.The normal control group was established (n =15).Total RNA of peripheral blood was extracted and transcripted into cDNA.Sybr green dye based real-time quantitative PCR method was used to compare the expression(indicated as 2-△Ct value) of CXC motif chemokine 10 (CXCL10),CC chemokine ligand 5 (CCL5),chemokine CXC subfamily receptor 3 (CXCR3),CC chemokine receptor 5 (CCR5) in children with HSP and those in the controls.Immunohistochemistry labeling technique was used to detect the distribution of pDC in renal tissues from renal biopsy,and the normal controls were established (n =3).Results The expression percentage of pDC in peripheral blood in active phase was 0.051 ± 0.039,significantly lower than those in remission phase (0.181 ± 0.082) and the normal controls (0.166 ± 0.079) (P ＜ 0.000 1).Chemokines genes CXCL10 and CCL5 were overexpressed in peripheral blood ceils of acute phase HSP children,but chemokine receptors CXCR3,CCR5 were lowly expressed compared with normal controls.There was almost no expression of pDC in the normal control renal tissues,while pDC was infiltrated in glomeruli of HSPN children.Conclusions The number of pDC and chemokines' expression in peripheral blood is abnormal,and the pathogenesis of nephritis may be involved with the pDC in peripheral blood to migrate to the renal tissues.
