OBJECTIVETo investigate the feasibility of using percutaneous K-wires fixation after manipulative reduction combining with gypsum or splint fixation for treatment of the Barton fracture of aged people.

METHODSFrom June 2011 to May 2013, 91 patients with closed and fresh Barton fracture were analyzed retrospectively which information was complete. According to different methods these patients were divided into three groups: 33 patients in group A were treated by simplex fixation of gypsum or splint after manipulative reduction, including 20 males and 13 females with an average age of (63.27 ± 5.83) years old; 35 patients in group B were treated by percutaneous K-wires fixation after manipulative reduction combining with gypsum or splint fixation, including 23 males and 12 females with an average age of (64.25 ± 4.53) years old; 23 patients in group C were treated by open reduction and internal fixation including 15 males and 8 females with an average age of (64.04 ± 4.83) years old.

RESULTSAll the patients were followed up for 10 to 16 months with an average of 12 months by the method of recheckging in outpatient clinic. According Dienst scoring system: in group A, the result was excellent in 15 cases, good in 7 cases, fair in 11 cases; in group B, excellent in 25 cases, good in 6 cases, fair in 4 cases; in group C, excellent in 16 cases, good in 5 cases, fair in 2 cases. The excellent and good rate of group C was better than that of group B and A, further more group B is better than group A. According to X- ray standard, in group A, 26 patients were acceptable, 7 patients were unacceptable; in group B,28 patients were acceptable, 7 patients were uacceptable; in group C, 19 patients were acceptable,4 patients were unacceptable; there were no statistical significant difference (P > 0.05). There were 18 patients with emerging recrispation in group A, 10 patients in group B, 6 patients in group C, the result of group B and C was better than that of group A, and there was no statistically significant between group B and C (P > 0.05).

CONCLUSIONUsing percutaneous K-wires fixation after manipulative reduction combining with gypsum or splint fixation for treatment of the Barton fracture of aged people is an effective method, it has advantages of micro-invasived, reliable fixation, less complication, not need to fix wrist joint and early functional exercise.

We revisited the "Xiao Chaihu Decoction event (XCHDE)" occurred in late 1980s in Japan and the Bupleuri Radix related adverse drug reaction (ADR) reports in China After careful review, comparison, analysis and evaluation, we think the interstitial pneumonitis, drug induced Liver injury (DILI) and other severe adverse drug envents (ADEs) including death happened in Japan is probably results from multiple factors, including combinatory use of XCHDE with interferon, Kampo usage under modern medicine theory guidance, and use of XCHD on the basis of disease diagnosis instead of traditional Chinese syndrome complex differentiation. There are less ADE case reports related to XCHD preparation in China compared to Japan, mostly manifest with hypersensitivity responses of skin and perfuse perspiration. The symptoms of Radix Bupleuri injection related ADEs mainly manifest hypersensitivity-like response, 2 cases of intravenous infusion instead of intramuscular injection developed hypokalemia and renal failure. One case died from severe hypersensitivity shock. In Chinese literatures, there is no report of the interstitial pneumonitis and DILI associated with XCHDG in Japan. So far, there is no voluntary monitoring data and large sample clinical research data available. The author elaborated the classification of "reevaluation" and clarified "re-evaluation upon events" included the reaction to the suspected safety and efficacy events. Based on the current status of the clinical research on the Radix Bupleuri preparations, the author points out that post-marketing "re-evaluation upon suspected event" is not only a necessity of continuous evaluation of the safety, efficacy of drugs, it is also a necessity for providing objective clinical research data to share with the international and domestic drug administrations in the risk-benefit evaluation. It is also the unavoidable pathway to culture and push the excellent species and famous brands of TCM to the international market, in that it enhances the pharmaceutical manufactures the ability to control enterprise risk and eliminate the negative impact on traditional Chinese medicine. With the widely used and ADR report concentrated Radix Bupleuri injection as an example, the author provide a new approach to post-marketing clinical research.

OBJECTIVETo study the clinical characteristics of hepatitis B virus-related acute-on-chronic liver failure patients with familial aggregation.

METHODS275 patients with hepatitis B virus--related acute-on-chronic liver failure were investigated. The patients were divided into familial aggregation and non-familial aggregation group basis on their epidemiological features. Clinical data and biochemical indicators between the two groups were analyzed statistically.

RESULTS93 of 275 patients (33.82%) case were family aggregation. There was no significant difference compared with chronic hepatitis B patients (38.3%). The mean age of the two groups was 45.98 and 43.61 years old, respectively (P > 0.05). The rates of liver cirrhosis in family aggregation group were significant higher than non-familial aggregation group (73.91% vs 58.24%, p < 0.05). Serum total (TBil) and prothrombin activities (PTA) were no significant difference between the two groups, but ALT level in familial aggregation group was much higher (407.80 U/L vs 256.45 U/L, P 0.05).

CONCLUSIONFamilial aggregation were not related to acute-on-chronic liver failure in chronic HBV hepatitis patients. But the rate of liver cirrhosis were higher in patients with familial aggregation.

The virus strains were isolated from the liver and spleen of the dead young ducks characterized with symptoms of hemorrhagic-necrotic hepatitis. These isolates could cause the death of muscovy duck-embryo and chick-embryo. 1-day-old birds infected with these isolates had the same character with clinically dead birds and the virus could be isolated from artificially infected birds. These isolates could proliferate in MDEF and result in CPE. The virus could proliferate in the cytoplasm in order of crystals and arranged in the latlic-like. The viron was shown spherical, icosahedron, cubic symmetry, no-envelope, with double-layered capsid, about 70 nm in diameter by electron microscopy. The genome segments of the virus were consisted of L1-3, M1-3 and S1-4, which were similar to that of avian reovirus (ARV). Compared to 68.2%, 69.3% - 70.1%, respectively. The system evolution analysis showed that S3 gene coding sigmaB protein was placed in different branch of MDRV and ARV, indicating that S3 gene of the virus was different from ARV and MDRV. The main clinical symptoms and lesions of ducklings caused by the virus were different from the diseases caused by MDRV and ARV. It was concluded that the virus was a Novel duck reovirus belonging to Orthoreovirus genus of the Reoviridae family.

OBJECTIVE: To explore an method for diffuse axonal injury (DAI) diagnosis and injury time estimation, the changes of beta-APP immunoreactivity and to observe the morphology of axonal in different parts of brain after experimental DAI injury. METHODS: The animal models of DAI was established according to the Marmarou's method. Immunohistochemistry and Gless staining were performed to observe the changes of beta-APP expression and the morphology of axon with the time elapsed after the DAI injury. RESULTS: In the brain injury group, the morphologic changes of axon in brain stem were showed as twisted, broken and swellen at 0.5 h, and the myelin sheaths broken could be observed, the retraction ball was found at 12 h. Those morphology changes further progressed at 12h, reached to peack up to 1 d, then repaired at 3 d, and recovered at 10 d; Meanwhile the analysis of beta-APP immunoreactivity was also showed a time-dependent difference as fellows: beta-APP expression begin at 3h, increased its immunoreactivity at 12h, reached to maximize at 1 d, decreased after 3 d, returned to basal level at 10 d. CONCLUSIONS The results suggest that beta-APP immunohistochemistry combine with Gless staining be sensitive methods for DAI diagnosis, they could discover the time-dependent changes of the axonal morphology.The changes beta-APP are quite regular and could be used for timing DAI injury.

Polyamides, containing N-methylpyrrole (Py) and N-methyl-imidazole (Im) amino acids, are synthetic oligomers programmed to read the DNA double helix in the minor groove with high affinities and sequence specificities resulting in modulation of gene expression. They are cell permeable, stable and have no cytotoxicity, which provide a promising tool of gene regulation. We describe here recent advances in the field of DNA binding polyamides, including pairing rules, specifities and affinities to DNA, synthesis methods, cellular and nuclear uptake properties, gene regulation and effectiveness in vivo. The potential problems and difficulties in future research are also discussed.

OBJECTIVETo observe the efficacy of Chinese herbs for supplementing qi and activating blood circulation (CHSQABC) on patients with acute coronary syndrome (ACS) and type 2 diabetes mellitus (DM) after successful percutaneous coronary intervention (PCI).

METHODSIn this ChiCTR-TRC-00000021, a total of 281 ACS patients complicated with type 2 DM after successful PCI were randomly assigned to the Western medicine treatment group (the control group, treated by routine Western medicine treatment) and the combined treatment group (the treatment group, treated by CHSQABC + routine Western medicine treatment). Patients in the combined treatment group took Xinyue Capsule (2 pills each time, 3 times per day) and Compound Chuanxiong Capsule (2 pills each time, 3 times per day for half a year and 1-year follow-ups). Primary endpoints covered incidence of death, nonfatal myocardial infarction (MI), ischemia-driven revascularization, and secondary endpoints included stroke, heart failure, and rehospitalization for ACS. At the same time scores for blood stasis syndrome (BSS) and the incidence of angina pectoris were evaluated before treatment, at month 1, 3, 6, 9, and 12 after treatment.

RESULTSThe incidence of ischemia-driven revascularization was obviously less in the treatment group than in the control group (P < 0.05). No patient had nonfatal MI in the treatment group, while 5 patients in the control group had it. The incidence of non-fatal MI showed an obvious lowering tendency in the treatment group, but with no statistical difference when compared with that in the control group (P > 0.05). Four patients readmitted to hospital in the treatment group, while 12 patients readmitted. There existed obvious tendency in the treatment group, but with no statistical difference when compared with that in the control group (P > 0.05). The incidence of angina was significantly lower in the treatment group at month 6, 9, and 12 than that at month 1 , but it was lower in the control group at 9 months (P < 0.05). The incidence of angina was 15. 4% in the treatment group, obviously lower than that in the control group (26.2%, P < 0.05). Compared with before treatment, scores for BSS were obviously lowered in the treatment group at 1, 3, 6, 9, and 12 months of treatment and in the control group at 3, 6, 9, and 12 months of treatment (P < 0.05). It was obviously lower in the treatment group than in the control group at 3, 6, 9, and 12 months of treatment (P < 0.01).

CONCLUSIONAdministration of CHSQABC combined routine Western medicine treatment could reduce the event of revascularization and post-PCI recurrent angina, and improve scores for BSS of ACS patients complicated with DM after PCI.

OBJECTIVETo study the application of stress X-ray of knee joint for the diagnosis ot medial collateral ligament injury.

METHODSFrom January 2008 to June 2011, 46 patients with medial collateral ligament injury were reviewed. Among the patients, 32 patients were male and 14 patients were female, ranging in age from 28 to 72 years, with an average of (49.46 +/- 22.54) years. Left knee joint injuries occurred in 22 patients, and 24 patients had injuries in right knee joint. Thirty-one patients were treated with surgical method, and 15 patients were treated with conservative method including 1 patient finally received operation after 3 months treatment with conservative method without effect. The injury side and normal side were observed by X-ray under stress and non-stress, as well as MRI. Operation was used to treat patients with medial gap markedly widen and the deep layer of medial collateral ligament injury in MRI. A line (line A) was drawn from medial condyle to lateral condyle of tibia platform. The line A was translated to the inner margin of condylus medialis femoris, which was line B. The perpendicular distance was measured, which was line C. The ration of space difference (R) was calculated by (space at stress force of injured side-space at non-stress force of injured side)/(space at stress force of normal side-space at non-stress force of normal side). The relationship between R and ligament injury type were investigated.

RESULTSThere were 17 patients with injuries of superficial lamella, 21 patients with injuries of deep lamella. Eight patients had associated injuries of articular capsule and posterior cruciate ligament. When R value was between 1.51 to 5.24, the injury of superficial ligament was found in 15 patients, actual injuries were found in 17 patients. When R value between 5.28 and 13.85, the injuries of bathypelagic ligament were found in 19 patients, actual injuries were found in 21 patients. When R value was between 15.61 and 26.25, the associated injuries of articular capsule and posterior cruciate ligament were found in 7 patients, actual injuries were found in 8 patients.

CONCLUSIONUsing the specific value as the standard of measurement can provide the quantizatily fractionation of the medial collateral ligament injury.
