Objective To investigate the imaging characters of abdominal cocoon.Methods Six cases of abdominal cocoon proved by surgery and pathologic findings were retrospectively analyzed. Abdominal plain X-ray and CT were performed in 6 cases.The gastrointestinal barium meal series were undergone in 4 cases.The imaging findings were analyzed.Results Abdominal plain X-ray suggested intestinal obstruction in 3 of 6 cases.The gastrointestinal barium meal showed"cauliflower sign"or "concertina pattern"in all of the 4 cases;CT images revealed a conglomeration of multiple small bowel loops in all 6 cases and the intestinal loops seemed to be encapsulated in a membranelike sac.Conclusion The imaging features of gastrointestinal barium meal and CT scan could suggest the diagnose of abdominal cocoon.

According to the designed specific primers of gene fragment based on the Salvia miltiorrhiza transcriptome data, a full-length cDNA sequence of SQS2 from S. miltiorrhiza f. alba was cloned by the method of reverse transcription polymerase chain reaction (RT-PCR). The SmSQS2 cDNA sequence was obtained, this sequence is named SmSQS2 and its GenBank registration number is KM244731. The full length of SmSQS2 cDNA was 1245 bp, encoding 414 amino acids including 5'UTR 115 bp and 3'UTR 237 bp. Sequence alignment and phylogenetic analysis demonstrated that SmSQS2 had relative close relationship to the SQS2 of S. miltiorrhiza. The induction of E. coli [pET28-SQS2] in different temperature, induction time, IPTG concentrations and density of inducing host bacterium (A600) were performed, Shaking the culture at 30 degrees C until the A600 is approximately 0.6 and add IPTG to final concentration of 0.2 mmol x L(-1), and then the optimal expression of SmSQS2 recombinant protein were accumulated after the induction time of 20 h. The research provided important base for the study of sterol and terpene biosynthesis of SQS2 in S. miltiorrhiza f. alba.

Effects of Cr 6+ concentration and culture time on four heavy metal removing strains,stability of these four strains removing Cr 6+,configuration changes inside or outside their cells,effects of Cr 6+ on soluble reductive sugar inside their cells,and effect of several factors on these strains had been studied,and the Cr 6+ resistance mechanisms of these strains have been discussed elementarily. The results showed that the Lethality of these strains caused by Cr 6+ was similar with one another, namely, increasing at first, then decreasing, and finally increasing again as culture time passed. Acclimatization of Candida sp. was better than Sporobolomycetaceae sp.,and the Cr 6+ resistance of Sporobolomycetaceae sp. 7-3 was the best of the four. The research also demonstrated that the metabolic activity of these strains had been influenced by Cr 6+ in a certain extent. Scanning electron microscopy,transmission electron microscopy,and atomic force microscopy observations approved that removal of Cr 6+ by Candida sp. was depended on both surface adsorption and intracellular accumulation. Effects of Cr 6+ concentration, pH, culture time, nitrogen source, carbon source and adsorption time on these strains are not the same.

One hundred and four patients aged of 65 years or above with cardiocerebral vascular diseases admitted from March to September 2008 were enrolled in the study. The fast plasma glucose (FPG) and 2 hours postprandial blood glucose (2 hPG) were tested. For patients with undiagnosed diabetes, if FPG≥7.0 mmol/L, 2 hPG≥11.1 mmol/L, their blood sugar index was checked again; if 2hPG was 7.8 mmol/L to 11.1 mmol/L, FPG from 6.1 mmol/L to 7.0 mmol/L, Oral glucose tolerance test (OGTT) was performed. Among the 104 patients, 30 cases of diabetes were diagnosed previously accounting for 28.8 %; 7 cases were newly diagnosed accounting for 6.8%; 21 cases were diagnosed as impaired glucose regulation accounting for 20.2%, with a total rate of sugar metabolism abnormality of 55.8%. The results indicate that blood glucose index should be regularly checked for elderly patients with cardiocerebral vascular diseases.

Objective To observe the effect of perioperative rehabilitation on anterior spinal cord syndrome caused by cervical hyper-flexion injury. Methods Sixty-nine inpatients with anterior spinal cord syndrome after cervical hyperflexion injury from January, 2012 to De-cember, 2014 were reviewed. 32 cases (group A) accepted systematic rehabilitations and other 37 cases (group B) did not. They were as-sessed with Japanese Orthopaedic Association (JOA) scores preoperatively and 1-year follow-up. Results All the patients succeeded in the operation. The JOA score improved more 1 year follow-up in group A than group B (t=2.538, P=0.044). Conclusion Systematic rehabilita-tion may work in the management of anterior spinal cord syndrome after cervical hyperflexion injury.

Objective To describe the clinical characteristics of a patient with Gitelman syndrome,and to identify the associated SLC12A3 gene mutations.Methods A suspected case of teenager-onset Gitelman syndrome was observed in our hospital.It was further confirmed by clinical manifestations and auxiliary examination.In addition,direct sequencing for the exons of SLC12A3 gene and CLCNKB gene region was conducted to identify the probable disease-associated mutations.Results The case showed characteristics of hypokalemia,hypomagnesemia,and low level of urinary calcium and onset by age of 18.By excluding the possibilities of long-term use of thiazide diuretics,laxatives,chronic vomiting and diarrhea,he was finally diagnosed as a case of Gitelman syndrome.Furthermore,by Sanger direct sequencing,2 coding variations were identified in SLC12A3 gene region,including T304M and L488P.L488P was a new heterozygous mutation.Conclusion Detection of SLC12A3 gene mutation could facilitate the diagnosis of Gitelman syndrome and improve prognosis.

Objective To study the mechanism, pathology, diagnosis and manage strategy of cervical fracture dislocation combined with anterior spinal cord syndrome (ASCS). Methods 32 cases of cervical fracture dislocation combined with ASCS from January 2012 to September 2014 were summarized. The mechanisms of injury and pathological characteristics were analyzed. All of them received surgical treatment. Anterior approach or anterior approach combined with posterior approach was chosen according to the characteristics of injury. Results All surgical treatments were successfully performed. There were 22 cases (68.75%) with hyperflexion, 5 cases (15.62%) with vertical hit, 1 case (3.12%) with hyperextension and 4 cases (12.5%) with multiple reasons. There were 4 cases (12.5%) with simple anterior dislocation, 28 cases (87.5%) with fracture combined with anterior dislocation. Only 8 cases were successfully diagnosed as ASCS, and the others (24 cases) were generally defined as spinal cord injury. Conclusion ASCS is not so rare. Hyperflexion injury is the most common mechanism. Anterior dislocation and fracture combined with anterior dislocation are the general types of pathology. Conscientious physical examination with CT and MRI can facilitate the diagnosis. Anterior approach or combined with posterior approach could be selected according to injury mechanism.

Objective To evaluate the cardiopulmonary exercise capacity in patients with essential hypertension (EH) complicating with or without left ventricular hypertrophy (LVH). Methods Graded maximal exercise test on the bicycle ergometer with respiratory gas analysis were performed in 30 gender and age matched normotensive controls, 40 EH patients without LVH and 30 EH patients with LVH (LVMI 125 g/m2 in males and 120 g/m2 in females). Metabolic equivalents (METs), oxygen uptake(VO2), oxygen uptake to body mass ratio (VO2/kg) and oxygen uptake to heart beat ratio (VO2/HR) at time of reaching anaerobic threshold (AT) and at maximal oxygen uptake (VO2max) were measured and compared. Results METs and VO2/kg were significantly reduced in EH patients with or without LVH compared with controls [ at AT, METs: 3.57±0. 8 and 4. 34±1.47 vs. 5.21±1.45 ; VO2/kg: 12. 38± 2. 85 and 14. 42±4. 33 vs. 18.48±4. 52, all P < 0. 01 ;at VO2max, METs:4.94±1.24 and 5. 90±1.51 vs. 6.96±1.85;VO2/kg:(17.20±4.34) ml·min-1·kg-1and (20.41±4.59 )ml · min-1·kg-1 vs. (24. 04±5.21) ml·min-1·kg-1, all P < 0. 01 ]. METs and VO2/kg at both time points were also significantly reduced in EH patients with LVH compared EH patients without LVH ( all P < 0. 05). The lower VO2/kg in hypertensive patients was significantly correlated to higher LVMI ( P < 0. 05 ). Conclusions Cardiopulmonary exercise capacity was reduced in hypertensive patients, especially in hypertensive patients with LVH.

OBJECTIVETo investigate the difference of serum high molecular weight alkaline phosphatase (HMAP) levels between biliary atresia (BA) and neonatal hepatitis (NH), and to develop a new differential method and early diagnostic indicators for cholestatic jaundice in neonates.

METHODSTotally 31 patients with cholestatic jaundice seen between Aug. 2000 and Feb. 2002, including 15 cases with BA, 16 cases with NH, 30 healthy infants and 30 infants with non-cholestatic jaundice were enrolled in this study. Serum samples were obtained from each subject by using venipuncture. The samples were stored at -80 degrees C and analyzed within 6 months. A murine hybridoma producing monoclonal antibody to human high molecular weight alkaline phosphatase (MoAb HMAP-1) was prepared by using partially purified HMAP from human serum as the immunogen. The antibody did not cross-react with other alkaline phosphatase (ALP) isozymes. A monoclonal antibody immunocatalytic assay for HMAP in serum was developed by using MoAb HMAP-1 bound to nitrocellulose membrane discs. The serum total ALP (TALP) and gamma-GT were determined in the meantime, the hepatobiliary ultrasonography and scintigraphy were performed too. The data were analyzed with t test, chi-square test and percentage. Comparisons were made between BA and NH with their sensitivity and specificity in different methods.

RESULTSSerum HMAP was detected in 14 of 15 patients of BA, in 2 of 16 NH patients, while in none of the healthy control group. The positive ratios of serum HMAP in BA and NH were 93.3% and 12.5%, respectively (P < 0.005). The sensitivity and specificity of serum HMAP in BA and NH were 93.3% and 87.5%, respectively. The sensitivity and specificity of TALP, gamma-GT and hepatobiliary scintigraphy were 80.0%, 73.3%, 86.7% and 62.5%, 68.8%, 62.5%, respectively, which were clearly lower than those of serum HMAP.

CONCLUSIONSThe determination of serum HMAP was more sensitive and specific than the other methods tested. Therefore the method can be used as a useful indicator for cholestatic jaundice in neonates, although it needs further study.
