OBJECTIVETo discuss the clinical effect of closed reduction and interlocking intramedullary nailing in the treatment of femoral shaft fracture.
METHODSFrom March 2006 to December 2011,103 patients with femoral shaft fracture were treated by closed reduction and interlocking intramedullary nailing including 76 males and 27 females with an average age of 36 years old ranging from 19 to 55 years old. According to AO classification,there were 64 cases with type A,27 with type B, 12 with type C. Thirteen cases were open fractures including 5 cases with Gustilo type I , 8 with Gustilo type II . The time of bone healing were observed after operation, the knee function recovery was evaluated by HSS scoring standard at 1 year after operation.
RESULTSThe intraoperative complications included femoral neck fracture in 1 case and proximal femoral fracture in 1 case,both of the patients were treated with reconstructive intramedullary interlocking nail and the fractures healed postoperatively. One patient was suffered from common peroneal nerve injury,which were fully recovered at 4 months later after medical treatment. All the patients were followed up from 12 to 28 months (averaged 22 months). All of the fractures were healed well and the average healing time was 3 to 9 months (averaged 5 months). All the hip joints were recovered to normal function. The average HSS was 90.89±5.06 at 1 year after operation.
CONCLUSIONInterlocking intramedullary nailing is the preferred treatment for patients with femoral shaft fracture. Carefully operating and closed reduction can reduce the complications.

OBJECTIVETo explore the clinical effect of the sacrococcygeal space injection for the treatment of failed back surgery syndrome.
METHODSFrom July 1998 to October 2012,47 patients with failed back surgery syndrome were treated and included 39 males and 8 females with an average age of 61.5 years old ranging from 35 to 89 years old. Among them,41 patients experienced one time of operation, 6 patients with twice of operation. Forty-one patients underwent single,bilateral fenestration or central laminectomy decompression, discectomy. Six patients underwent total laminectomy discectomy and inter body fusion and pedicle screw fixation. All patients were examined by X-ray plain film, CT or MRI before treatment. The anticoagulation was discontinuation before treatment. The needle was put into the sacrococcygeal gap at prone position in the sense of frustration,suction without cerebrospinal fluid and blood,with injection of Mailuoning (Chinese characters: see text) 15 ml. The pain was assessed by VAS before and after treatment. The Oswestry low back pain disability index and survival quality interference degree were evaluated.
RESULTSAt 1 month after treatment,the pain VAS decreased from 59.24 +/- 17.35 before treatment to 19.19 +/- 11.19 after treatment (P < 0.05); The Oswestry low back pain disability index decreased from (41.35 +/- 9.87)% before treatment to (23.17 +/- 17.56)% after treatment (P < 0.05); The survival quality interference degree decreased from 6.5 +/- 2.2 before treatment to 2.6 +/- 1.4 after treatment (P < 0.05).
CONCLUSIONThe sacrococcygeal gap injection for treatment of failed back surgery syndrome has advantages of simple, safe, fewer complications, and low treatment cost.

OBJECTIVETo evaluate the reliability, validity, and responsiveness of traditional Chinese medicine (TCM) clinical outcomes rating scale for heart failure (HF) based on patients' report.
METHODSTCM clinical outcomes rating scale for HF (TCM-HF-PRO) were evaluated based on 340 HF patients' report from multiple centers. The completion of the investigation was recorded. Cronbach's α coefficient and split-half reliability were used for reliability analysis, and factor analysis was used to assess the construct validity of the rating scale. Pearson correlation analysis was then used for criterion validity analysis. Discriminant analysis was used to assess the responsiveness of the scale. All 340 HF patients having complete TCM-HF-PRO data were assigned to the treatment group and the control group by central randomization. The total TCM-HF-PRO scores of the two groups were compared using paired t-test to reflect the longitude responsiveness of the scale before treatment and at week 2 after treatment.
RESULTS(1) The recycling rate of the scale was 100.0%. One of them was not filled completely, which was rejected thereby. So the completion rate was 99.7%. The completion time for TCM-HF-PRO scale ranged 15 to 25 min. (2) The Cronbach's α coefficient of rating scale was 0.903, split-half reliability was 0.844 and 0.849. (3) Confirmatory factor analysis showed that 7 factors and items formed according to maximum load factor basically coincided with the construct of the rating scale, 7 factors accumulated contribution rate was 43.8%. TCM clinical outcomes rating scale for HF based on patients' report was relatively better correlated with the Minnesota living with HF questionnaire (r = 0.726, P < 0.01). (4) Discriminant analysis showed that the rating scale correctly classified more than 78.8% of case studies having confirmed initial differential diagnosis by experts. The total scale of the rating scale decreased more in the two group after treatment, with significant difference as compared with before treatment (P < 0.01.
CONCLUSIONTCM clinical outcomes rating scale for HF based on patients' report had good reliability, validity and responsiveness, hence it could be used to assess clinical efficacy for HF patients.

In this study, the general bacterial probe and specific cellulolytic bacterial probes were used to quantify the bacteria in rumen. The total RNA were extracted and then hybridized with general bacterial probe after a dilution of concentration. The result showed that there was a high correlation between the hybridization signal and the dilution of total bacterial RNA. Based on the result above, the quantities of three cellulolytic bacteria in rumen sample were detected. The comparative RNA percentage of three cellulolytic bacteria to total bacterial RNA were similar to the previous reports. It can be concluded that the quantification of bacteria in rumen could be conducted by this approach, and which could be used in future research.

OBJECTIVE:
Mitochondrial deoxyribonucleic acid (mtDNA) 8344 A>G (m.8344A>G) mutation is the common mutation associated with mitochondrial myoclonus epilepsy with ragged-red fibers (MERRF) syndrome. Herein we report a rare case with mitochondrial encephalopathy, lactic acidosis and stroke-like episodes/MERRF/Leigh (MELAS/MERRF/Leigh) overlap syndrome caused by m.8344A>G mutation.
METHODS:
The clinical and imaging data of the patient were collected and an open muscle biopsy was carried out. We further employed molecular genetic analyses to detect mtDNA mutation in the proband and his mother. And then a clinical and neuroimaging follow-up was performed.
RESULTS:
This patient was a 25-year-old male, who developed exercise intolerance since the age of 6. At age 10, he suffered from acute episodes of hemianopia, and cranial magnetic resonance imaging (MRI) showed occipital stroke-like lesions and cranial magnetic resonance spectroscopy (MRS) revealed a lactate peak corresponding to the lesion. After that the patient presented slowly progressive psychomotor decline. He had myoclonic seizures and cerebellar ataxia since the age of 12. At age 21, he was admitted to our hospital because of confusion and cranial MRI revealed symmetrical lesions in bilateral posterior putamen, thalami and midbrain. Then repeated MRI showed progression of original lesions and new frontal multiple stroke-like lesions. Symptomatic and rehabilitation treatment relieved his condition. Follow-up cranial MRI at age 24 showed the lesions in basal ganglia and thalami diminished, and the midbrain lesions even completely vanished. Muscle pathology indicated the presence of numerous scattered ragged-red fibers (RRF), suggestive of a mitochondrial disorder. Polymerase chain reaction-restricted fragment length polymorphism (PCR-RFLP) detected the m.8344A>G mutation of the MT-TK gene encoding mitochondrial transfer RNA for lysine in the patient's blood. Next generation sequencing (NGS) of the whole mitochondrial genome identified that the proportion of m.8344A>G was 90%, and no other mtDNA mutation was detected. Sanger sequencing further identified this mutation both in the proband and his mother's blood, although the mutation load was much lower in his mother's blood with approximately 10% heteroplasmy.
CONCLUSION
The present study is the first to describe a patient with m.8344A>G mutation in association with the MELAS/MERRF/Leigh overlap syndrome, which expands the phenotypic spectrum of the m.8344A>G mutation.

This study was designed to use iTRAQ technology coupled with 2D LC-MS/MS to study the comparative proteomics of different processing technology for pilose antler. 1015 proteins were identified with 2D LC combined with MOLDI TOF/TOF mass spectrometry. Comparative analysis with Protein Pilot (Version 4.5) revealed that 87 proteins were changed (P ≤ 0.05, the ratio of > 1.50 or < 0.60 as the threshold selection of difference proteins), of which 24 were up regulated and 33 were down regulated in the traditional frying process (TFP) compared with the fresh pilose antler (P ≤ 0.05). 7 significant different proteins (P ≤ 0.001), most of these significantly changed proteins were found to be involved in calcium ion binding and ATP binding associated with human healthy. Freeze drying with protective agent (FDP) (Trehalose) can improve the content of significantly different proteins (P ≤ 0.001) including Collagen alpha-1 (XII) chain (COL12A1) and Collagen alpha-1 (II) chain (COL2A1). The significant function involves in platelets activating, maintenance of spermatogonium, and disorder expression in tumor cells. The functional annotation by Hierarchical clustering and GO (gene ontology) showed that the main molecule functions of the proteins significantly changed in these processes were involved in binding (52.7%), catalytic (25.3%), structural molecule and transporter (6.6%).

Single nucleotide polymorphisms (SNP) is an important molecular marker in traditional Chinese medicine research, and it is widely used in TCM authentication. The present study created a new genotyping method by combining restriction endonuclease digesting with melting curve analysis, which is a stable, rapid and easy doing SNP genotyping method. The new method analyzed SNP genotyping of two chloroplast SNP which was located in or out of the endonuclease recognition site, the results showed that when attaching a 14 bp GC-clamp (cggcgggagggcgg) to 5' end of the primer and selecting suited endonuclease to digest the amplification products, the melting curve of Lonicera japonica and Atractylodes macrocephala were all of double peaks and the adulterants Shan-yin-hua and A. lancea were of single peaks. The results indicated that the method had good stability and reproducibility for identifying authentic medicines from its adulterants. It is a potential SNP genotyping method and named restriction endonuclease digest - melting curve analysis.

Objective To explore the expression and its implication of angiogenesis and invasiveness related factor in primary and recurrent glioma. Methods Expressions of vascular endothelial growth factor (VEGF), matrix metalloproteinase-2 (MMP-2) and MMP-9 were detected by immunohistochemical technique. The morphological characteristics of ultrastructure of glioma were observed by transmission electron microscope (TEM). Results The expressions of VEGF, MMP-2 and MMP-9 varied in different grades of primary glioma. With the elevation of the malignant degree of the primary glioma, positive staining rates of VEGF, MMP-2 and MMP-9 increased significantly. The expression of VEGF correlated with both MMP-2 and MMP-9 expression. Compared with the primary glioma, the immunoreactivities of VEGF, MMP-2 and MMP-9 in recurrent glioma increased, especially in those with more severe malignancy. Under transmission electron microscope, endothelial cells markedly proliferated and protruded from the deficiency of basemembrane, concomitantly with edema of the extracapillary gap, plasma extravasation as well as some small worm-eaten caverns in the basemembrane.Conclusion VEGF, MMP-2 and MMP-9 play important roles in glioma angiogenesis and invasiveness.Inhibition of their expressions may be a useful therapy to glioma.
