OBJECTIVETo observe the effect and safety of plastering Chinese Compound Shenhuang Ointment (CSO) at Shenque (RN8) in promoting the rehabilitation of postoperative gastrointestinal dysfunction patients of qi stagnation blood stasis syndrome (QSBSS).

METHODSA prospective, multi-centered, randomized, double-blinded, controlled trial was conducted in 220 postoperative gastrointestinal dysfunction patients of QSBSS. They were randomly assigned to two groups, the CSO group (110 cases) and the placebo group (110 cases). CSO was plastered at Shenque (RN8) for 5 days after operation. The time of exhaustion, defecation, the recovery of intestinal peristalsis, integrals of TCM syndrome, and serum levels of motilin (MOT)and somatostatin (SS) were observed.

RESULTSCompared with the placebo group, the condition of exhaustion and defecation, the recovery of intestinal peristalsis on the 3rd day after operation was all improved (P < 0.05). The integrals of TCM syndrome at day 2, 3, and 4 were more significantly lowered in the CSO group than in the placebo group (P < 0.01, P < 0.05). The total effective rate of TCM syndrome was 95.3% in the CSO group, better than that in the placebo group (91.8%, P < 0.05). Compared with the placebo group, the serum MOT level increased and the serum SS level decreased at day 5 after operation in the CSO group (P < 0.05).

CONCLUSIONSThe plastering of CSO at Shenque (RN8) could advance the time of exhaustion and defecation, and improve patients' clinical symptoms. And patients could tolerate well.

Objective To investigate the correlation between ~(18)F-fluorodeoxyglucose (FDG) uptake and hypoxia inducible factor1α (HIF-1α) level,microvessel density (MVD) in human gliomas.Methods ~(18)F-FDG PET scan was performed preoperatively in 41 patients with gliomas (including 23 highgrade and 18 low-grade tumors).The ratios of maximum standardized uptake value(SUV_(max))between tumor (T)and contralateral white matter (WM) were calculated (T/WM).Immunohistochemical stain methods were used to evaluate the level of HIF-1α and measure the MVD in tumors.Correlation analysis between SUV_(max) of T/WM and HIF-1α level,MVD wag performed.The t-test,one-way ANOVA test,Spearman rank correlation and Wilcoxon signed-rank test were calculated using SPSS 11.5 software.Results (1)The SUV_(max) of T/WM,HIF-1α level and MVD in high-grade and low-grade tumors groups were 3.39±1.43,95.7% and 44.13±16.1 vs 1.46±0.55.55.6% and 18.83±7.07,respectively.The difierences of SUV_(max) of T/WM,HIF-1α level and MVD between two groups were statistically significant (t=-5.921,z=-3.938,t=-6.745,all P＜0.05).(2)Among 41 gliomas,the strong positive expression of HIF-1α was observed in 8,mederate in 9,weak in 15 and negative expression was found in 9,SUV_(max) of T/WM and MVD increased with increasing HIF-1α level.The differences of SUV_(max) of T/WM and MVD among 4 different groups were statistically significant (F=7.41,P＜0.05).(3) The MVD of all gliomas was ranged from 9.76 to 94.52,which correlated with SUV_(max) of T/WM(r=0.759,P＜0.05).Conclusions The SUV_(max) of T/WM correlates with HIF-1α level and MVD in gliomas.Therefore,~(18)F-FDG PET provides preoperatively a noninvasive assessment of hypoxia or angiogenesis in human glionma.

ObjectiveTo investigate the relationship between the degenerative mechanisms of lumbar intervertebral disc (LID) and apoptosis.MethodsThe total RNAs were isolated from human LID tissues. Both the mRNAs from the degeneration and normal LID were reversely transcribed to the cDNAs. The cDNAs were labeled with the incorporations of fluorescent dUTP, for preparing the hybridization probes. The mixed probes were then hybridized to the cDNA microarray. After high-stringent washing, the cDNA microarray was scanned for the fluorescent signals and analyzed by computer image analysis. The apoptotic status and the expression of Bcl-2 and Bax in 12 cases of degenerative LID and 10 cases of normal LID were detected with TdT-mediated dUTP-biotin nick end labeling (TUNEL) and immunohistochemistry methods.ResultsAmong the 4096 targets, there were 10 genes related to apoptosis. The expression related to Bax protein gene was up-regulated and it was down-regulated for Bcl-2 protein. In group of normal LID, the average apoptotic index (AI) was (24.897±3.620); percentage of Bcl-2 positive cells was (31.440±4.150)%; percentage of Bax positive cells was (29.372±2.588)%, average optical density (OD) values of positive particles were (0.183± 0.010 ), ( 0.203 ±0.012) and (0.169±0.005) respectively. In group of degenerative LID, the average AI was (49.232±3.440); percentage of Bcl-2 positive cells was (18.239±2.470)%; percentage of Bax positive cells was (52.349±3.764)%; average OD values of positive particles were (0.152±0.003), (0.310±0.008) and (0.262±0.014) respectively. There were significantly differences in AI and expressions of Bcl-2 and Bax proteins between normal LID and degenerative LID (P<0.05).ConclusionCell apoptosis plays an important role in the process of LID degeneration. Both Bcl-2 and Bax take part in the occurrence and progression of LID.

The abnormalities of the cervical curvature were classified as over-curvature (>45°), hypo-curvature (0°～30°), the straightened cervix (0°), backward curvature(0°～―20°), multiple curvatures (the cervical curvature showed "S" shaped). The C_5 subluxation were restored with manipulation in patients with hypo-curvature and straightened cervix, or other vertebra subluxation in multiple curvatures. Results1~4 yeared follow-up, 127 cases were excellently well being, 59 were well being, 23 were improved.ConclusionManipulation is effective on abnormalities of cervical curvature.

OBJECTIVETo screen genes with abnormal expression in poorly-differentiated human lung adenocarcinoma at stage I with cDNA chip.

METHODSThe mRNA was extracted from cancer tissue and matched normal lung tissue, and was labeled by Cy5-dUTP or Cy3-dUTP as probes. Subsequently, the mixed probes were hybridized to the cDNA chip containing 8192 genes. The information was obtained by managing the cDNA chip with ScanArray4000 scanner and GenePix3.0 software.

RESULTSFive hundred and eighty genes were differentially expressed between cancer and normal lung tissue. Compared with normal lung tissue, 405 genes were up-regulated and 175 genes were down-regulated in cancer tissue. These genes are involved in different cell activities such as growth regulation and signal transduction. Among the 66 genes with remarkable differential expression between the two tissues, 39 were up-regulated and 27 down-regulated.

CONCLUSIONMany different kinds of genes are possibly involved in the initiation and progression of human lung adenocarcinoma. cDNA chip technique might be a useful method in screening lung cancer implicated genes.

This paper reports the clinical and genetic characteristics of a case of combined pituitary hormone deficiency type I (CPHD1) caused by POU domain, class 1, transcription factor 1 (POU1F1) gene variation. A 2 years and 3 months old girl mainly presented with short stature, special facial features of prominent forehead, enophthalmos, and short mandible, loose skin, central hypothyroidism, complete growth hormone deficiency, and anterior pituitary hypoplasia. Gene analysis identified a novel heterozygous mutation, c.889C>T (p.R297W), in POU1F1 gene, and this locus of her parents was wild-type. This mutation was analyzed as a possible pathogenic variant according to the guidelines of the American College of Medical Genetics and Genomics, which has not been previously reported in the literature and conforms to the autosomal dominant inheritance. This child was diagnosed with CPHD1. Her height increased by 19.8 cm and showed a catch-up growth trend after one year of combined treatment with growth hormone and euthyrox. This study enriches the mutation spectrum of POU1F1 gene and has important significance for the diagnosis and classification of combined pituitary hormone deficiency.

BACKGROUND: For recent decades, there has been a younger tendency in age of occurrence of the cervical spondylosis, and posterior fusion is the main method for cervical degeneration and injury, but no relevant fixation parameters are available in clinical practice for adolescents. OBJECTIVE: To measure the anatomical parameters of C4-6posterior fixation in the adolescents aged 12-14 years after three-dimensional reconstruction. METHODS: Twenty-one adolescents aged 12-14 years, who underwent cervical examination at the Affiliated Hospital of Inner Mongolia Medical University and Department of Orthopedics of the Second Hospital of Ulanqab between January 2014 and December 2016 were randomly selected, and the CT data of the C4-6were collected, and then imported into Mimics16.01 software for three-dimensional reconstruction. We measured the anteroposterior and transverse diameters and the heights of the vertebral body, anteroposterior and transverse diameters of the transverse foramina, angles of the left and right pedicle axes to sagittal and horizontal axes, and left and right pedicle axis lengths. RESULTS AND CONCLUSION: (1) Both anteroposterior and transverse diameters of the transverse foramina were increased with vertebral level incveasing. Both angles of pedicle axis to sagittal and horizontal axes, and pedicle axis lengths were increased with vertebral level. The anteroposterior diameter of the vertebral body at C4-6was in the range of 6.0-8.0 mm, the transversal diameter was in 25.0°-30.0°, the angle between the posterior screw and the horizontal axis was 29.0°-35.0°; in the sagittal plane, the angle to the sagittal axis was no more than 5°; and the pedicle screw path length was in 6-7 mm. (2) These results show the anatomical parameters of C4-6posterior fixation in the adolescents aged 12-14 years are successfully obtained by three-dimensional reconstruction.

OBJECTIVETo improve the mini-modified semi solid rappaport vassiliadis most probable number (mini-MSRV MPN) method for Salmonella detection.

METHODSBased on the mini-MSRV MPN method,Buffered Peptone Water (BPW) was modified as one step enrichment medium and Modified Semi Solid Rappaport Vassiliadis (MSRV) medium was ameliorated as modified MSRV for Salmonella detection under standard Salmonella addition recovery. A total of 154 raw chicken samples, 48 swabs of pheasantry and 48 poultry dung samples were collected to compare the detection results of Salmonella by using improved mini-MSRV MPN, mini-MSRV MPN and regular most probable number (MPN) method.

RESULTSSalmonella recovery was < 2.7 MPN/g when the standard Salmonella addition was at the concentration of 0.9 CFU/g when the mini-MSRV MPN method was employed. If the standard Salmonella addition were at 9.0 and 90.0 CFU/g, the recoveries of bacteria were 10.1 and 94.0 MPN/g, and the average recovery rate was 112% and 104%, respectively. Salmonella detection rate of modified mini-MSRV MPN, mini-MSRV MPN and regular MPN method was 18.4% (46/250), 5.2% (13/250) and 6.0% (15/250), respectively. The detection rate was higher for modified mini-MSRV MPN method than of the other two methods (χ(2) values were 19.68 and 17.82, respectively, all P values < 0.05). The detection quantity of Salmonella (medians were 21.0, < 2.7 and < 3.0 MPN/g, respectively). The quantity detected by modified mini-MSRV MPN method was higher than that of the other two methods (both Z values were 5.71, both P values < 0.05).

CONCLUSIONModified mini-MSRV MPN method is an accurate method for foodborne Salmonella detection.

OBJECTIVETo summarize our experiences in the treatment of type C3 (AO/OTA) distal radius fractures fixed with AO 2.4 mm locking plates combined with percutaneous pinning after manipulative reduction.

METHODSFrom May 2009 to March 2012, 19 patients (2 cases of both sides) with type C3 (AO/OTA) distal radius fractures were treated with volar locking plates combined with percutaneous pinning for distal radius after manipulative reduction. Among the patients, the average age was (45.3 ± 17.4) years old (ranged, 31 to 66 years old). The fracture were complicated with ulnar styloid fracture in 14 wrists and 6 wrists had distal radioulnar joint instability. All the patients had closed fracture and the mean duration was (6.7 ± 3.5) days (4.5 to 9 days). The Henry approach was applied to expose the fracture site. Joint capsule and ligaments were retained for indirect reduction. After indirect reduction, the poking reduction technique was used to correct the residual compression, and congruence of distal ulnar radial joint was verified under fluorscopic guidance. Styloid process was first pinned percutaneously and then AO 2.4 mm volar locking plate was used to support rigid fixation. The fractures complicated with distal radioulnar joint instability and ulnar styloid fracture were treated with forearm plaster support in supination for 6 weeks.

RESULTSNineteen patients (21 wrists) were followed up for an average duration of 10.5 months (ranged, 7 to 17 months). Radiographic bone union of distal radius was achieved in all cases, nonunion of the ulnar styloid occurred in 3 cases, and no distal radioulnar joint instability occurred. Tendon irritation was found in 2 cases and disappeared after the internal fixation was removed. The volar tilt, radial angle, radial length, incongruence of articular surface and distal radioulnar joint were observed at the follow-up. According to Batra and Gupta scoring system, 13 wrists were assessed to have a score of more than 80, 5 wrists 70 to 90, 3 wrists less than 70. Meanwhile, the subjective and objective evaluation was executed,range of motion of wrist, residual deformity and complications were observed. According to Sarmiento's modification of the system of Gartland and Werley, 17 wrists got an excellent result, 3 good and 1 fair.

CONCLUSIONType C3 (AO/OTA) distal radius fractures could be managed with manipulative reduction. Locking plate internal fixation combined with percutaneous pinning can offer enough support for early mobilization and rehabilitation, resulting in a better clinical outcome and satisfactory prognosis.
