Objective To evaluate the multi-slice spiral CT scan of liver dynamic dual-phase three-dimensional vascular imaging portal phase clinical value. Methods 80 cases in clinic, who were patients with liver function and imaging diagno- sis of liver and portal hypertension in liver cirrhosis, and 20 cases of healthy persons were carried out multi-slice spiral CT dual-phase scanning. The workstation used volume rendering techniques (VR) and maximum density multi-planar recon- struction technique for reconstruction. Results The hepatic arterial phase VR image and MIP MPR images can clearly show the celiac trunk, splenic artery, hepatic artery or artery and its branches, including 2-3 grade tumor blood supply variation of blood vessels and blood vessels, the portal venous phase, VR images and MIP MPR images clearly show the 1-6 level structure and the portal vein and hepatic vein branches of 1-3, with strong three-dimensional sense of space. Conclusion The multi-slice spiral CT three-dimensional reconstruction of portal vein imaging is a fast and effective non-invasive an- giography techniques, contributing to the clinical choice of reasonable efficacy of treatment programs and follow-up.

OBJECTIVETo explore the clinical efficacy of self-made Kirschner wire hook in the treatment of severely displaced proximal humerus fractures in children.

METHODSFrom January 2007 to February 2012,35 children with severely displaced proximal humerus fractures were treated with self-made Kirschner wire hook fixation,including 25 boys and 10 girls with an average age of 13.2 years old ranging from 5 to 17. The duration from injury to operation was 1 to 10 days with an average of 4.5 days. Preoperative diagnoses were confirmed by X-ray films as type III in 26 cases and type IV in 9 according to the Neer-Horwitz classification of the proximal humerus fractures. All fractures were close fracture without nerve or vascular injuries. Anatomical reduction was achieved by open reduction and the fractures were fixed by self-made Kirschner wire hook. Intra-operative and postoperative complications, postoperative radiographic examination, upper extremity length and range of shoulder motion were observed and recorded. Neer score system was used to evaluate shoulder function.

RESULTSAll patients were followed up from 6 to 18 months with an average of 12.1 months. The mean Neer score of the injured side was 94.2 +/- 4.8 (ranged, 84 to 99), 30 patients got an excellent result and 5 good according to the Neer scores. The X-ray showed all the fractures healed without shortening deformity or epiphyseal arrest at early stage. There were no complications related to the implant including loosening or breakage of the self-made Kirschner wire hook. The range of shoulder motion in the injuried side was similar to the normal side, except in abductor lift. All the patients could participate in normal physical activities.

CONCLUSIONThe method of open reduction and fixed with self-made Kirschner wire hook is a safe,effective,convenient treatment for severely displaced proximal humeral fractures in children.

OBJECTIVETo compare efficacy of unilateral external fixators and locking compression plates in treating type C fractures of the distal radius.

METHODSFrom January 2009 to June 2010, 76 patients with distal radius fracture were treated with LCP and external fixators, 54 patients were followed up. Among them, 29 cases were male and 25 cases were female with an average age of 45.31 (ranged, 24 to 68) years old. There were 29 patients in LCP group. According to AO classification, 8 cases were type C1, 7 cases were type C2 and 14 cases were type C3. There were 25 cases in external fixators group. According to AO classification, 6 cases were type C1, 8 cases were type C2 and 11 cases were type C3. Radial height, volar tilt and radial inclination were compared, advanced Gartland-Werley scoring were used to assessed wrist joint function after 6 and 12 months' following up.

RESULTSTwo cases were suffered from nail infection in external fixators group. Fifty-four patients were followed up from 12 to 24 months with an average of 21.3 months. Radial height was (9.60 +/- 0.72) mm, volar tilt was (9.55 +/- 0.80) degrees and radial inclination was (21.40 +/- 0.78) degrees in LCP group,while those were (9.40 +/- 0.70) mm, (9.47 +/- 0.71) degrees and (21.20 +/- 0.73) degrees in external fixtors group, and with no statistical significance (P>0.05). Advanced Gartland-Werley score after 6 months' following up was 3.31 +/- 1.17 in LCP group, 5.56 +/- 1.58 in external fixtors group, and with significant difference (t=-5.99,P<0.05); after 12 months' following up, advanced Gartland-Werley score was respectively 2.66 +/- 1.01 and 3.08 +/- 1.00, but with no statistical meaning (t=-1.55, P>0.05).

CONCLUSIONLCP and external fixtors can receive good curative effects in treating type C distal radius fracture, and LCP can obtain obviously short-term efficacy, while there is no significant difference between two groups in long-term results. For serious distal radius comminuted fracture which unable to plate internal fixation, external fixators is a better choice.

In order to clarify the chemical constituents of Cistanche deserticola cultured in Tarim desert, a systematically phytochemical investigation was carried out. The chemical constituents were isolated by column chromatography, such as silica gel, Sephadex LH- 20, MCI gel, ODS and semi-preparative HPLC, and their structures were determined on the basis of MS, NMR spectroscopic analysis and/or comparison with literature data. Eleven lignans were isolated from the 85% ethanol extract of the stems of C. deserticola cultured in Tarim desert. Their structures were identified as (+)-syringaresinol-4'-O-β-D-glucopyranoside (1), (+)-isoeucommin A (2), eucommin A (3), (+)-pinoresinol monomethylether β-D-glucoside (4), lariciresinol 4'-O-β-D-glucopyranoside (5), lariciresinol 4-O-β-D-glucopyranoside (6), conicaoside (7), dehydrodiconiferyl alcohol 4-O-β-D-glucopyranoside (8), dehydrodiconiferyl alcohol γ'-O-β-D-glucoside (9), citrusin A (10), and alaschanioside A (11). Compounds 1, 3-7, 10 and 11 were isolated from this genus for the first time, and compounds 2, 8 and 9 were obtained from this species for the first time.

In this study, ITS2 barcode was used to identify Bupleurum chinense and B. longiradiatum. The ITS2 regions of 48 samples were amplified and sequenced. The sequences obtained above were aligned and the K2P distances were calculated. We used three methods, BLAST1, nearest distance and phylogenetic tree (NJ-tree), to test the identification ability. The results showed that the maximum intraspecific genetic distance of B. chinense was 0.013, and the minimum interspecific genetic distance between B. chinense and B. longiradiatum was 0.049. The NJ-tree can easily identify B. chinense and B. longiradiatum. Therefore, the ITS2 barcode is suitable to identify B. chinense and B. longiradiatum.

Objective To evaluate the diagnosis and treatment of hepatic cystic echinococcosis with biliary complications. Methods 284 patients with hepatic cystic echinococcosis (CE) with biliary complications were surgically treated from January 2002 to January 2009 in our hospital. A summary of the surgical procedures was categorized and compared in the current study. Results (1) Intrabiliary rupture of CE with obstructive jaundice and (or) inflammation of bile duct (51 patients). The diagnosis of biliary complications of hepatic hydatid cyst was difficult on ultrasound and CT, with sensitivity rates of 78.4% and 85.7%, respectively. MRCP was an effective, noninvasive and useful diagnostic tool in difficult cases; ERCP was used as the gold standard in confirmation. Biliary fistulae were seen in 3 patients (10.7%) treated by suturing the rupture site. In the non-sutured group, 17 patients (74%) developed biliary fistulae after surgery (P＜0.01). In three patients the fistula was a high-output type (the fistula output was greater than 250 ml/d). (2) CE communicated with the bile duct and (or) infection (210 patients): The cavity-related problems and draining time in group C (no bile duct exploration and decompression) were significantly higher than group A (biliary system explored and decompressed through the cystic duct) and group B (biliary system explored and decompressed through the common bile duct), while cavity-related problems and draining time between the A and B groups showed no significant difference. Biliary tract-related problems in group A was significantly lower than group B (P＜0. 05). Conclusions (1) MRCP was an effective, noninvasive and useful diagnostic tool; ERCP was used only as the gold standard in confirming intrabiliary rupture of liver cystic hydatid disease, and also as an effective technique for treating extended postoperative external biliary fistula. (2) This study indicated that suturing the communication at the rupture site and biliary decompression were effective with low morbidity and mortality rates. (3) Cholangiography and common bile duct exploration through the cystic duct could solve the cavity-related problems while avoiding the T-tube related problems.
