Objective: The HPLC method was established for assessment of quality of Lasiosphaera seu Calvatia (LSC) based on the determined indicator of ergosterol. The contents of ergosterol in 42 batches of LSC were comparatively analyzed. Methods: The contents of ergosterol in LSC from different origins were determined by HPLC. The conditions were as follows: BDS Hypersil C18 column (250 mm × 4.6 mm, 5 μm); flow rate: 1.0 mL/min; detection wavelength: 282 nm; column temperature: 30 ℃; injection volume: 20 μL; mobile phase: acetonitrile (A): 0.1% formic acid (B) as the mobile phase gradient elution: 0-15 min, 95% A, 15-50 min, 100% A. Results: The HPLC method to determine the ergosterol content of puffball was established.The ranges of ergosterol contents among different samples was 0.009 9%-0.150 3%. Conclusion: The contents of ergosterol in different LSC are obviously different, and the quality of commercial LSC is not coincident. So the quality control of LSC a needs further normalization and standardization. The data in this paper would provide a reasonable reference for the quality control of LSC.

OBJECTIVETo study the therapeutic efficacy of manipulative reduction and percutaneous pin fixation for the treatment of severely displaced distal tibial fractures in children.

METHODSFrom May 2009 to December 2012,56 children with severely displaced distal tibial fractures were analyzed, who had been treated with manipulative reduction and percutaneous pin fixation. Preoperative fractures were confirmed as severely displaced fractures by X-ray apparatus. There were 33 boys and 23 girls,ranging in age from 3 to 14 years, with an average of 10.1 years. All the fractures were closed without vascular or nerve injuries. According to the bone fracture type, under C-arm fluoroscopy, functional reduction was achieved by manipulative reduction. The fractures were fixed with percutaneous pins. Postoperative X-ray confirmed the functional reduction. Follow-up indexes were recorded: intra-operative and postoperative complications,postoperative radiographic examination, lower extremity length and range of ankle motion. Ankle score system of Teeny was used to evaluate ankle function.

RESULTSAll the patients were followed up, and the duration ranged from 3 to 46 months, with an average duration of 19.4 months. According to the Teeny score standard, 35 patients got an excellent result, 7 good and 3 fair. Pin track reaction was found in 4 cases. The X-ray showed all the fractures healed without shortening deformity or epiphyseal arrest at early stage. All the patients could participate in the normal physical activities, having a normal range of motion and excellent strength of the ankle joint.

CONCLUSIONThe method of manipulative reduction and percutaneous pin fixation is a safe and convenient treatment for severely displaced distal tibial fractures in children. It has several advantages as follow: micro-trauma, tiny tissue damage, firm fixation, and the patients can exercise the function of ankle early, suggesting that it is an effective treatment method.

"Omics" and bioinformatics have brought new ideas to the study of traditional Chinese medicine. This study used metabonomics and network pharmacology to investigate the pharmacodynamic basis and regulation of Qishen Yiqi dropping pill (QDP) improving cardiac energy metabolism in rats with heart failure (HF). ¹H NMR metabonomics analysis showed that eight metabolites, including carnitine, glutamine, creatine, proline, homocitrulline, lactic acid, taurine and alanine appeared significant callback after QDP treatment for HF. The results indicate that QDP regulates the metabolism of carbohydrate, lipid, ATP and protein. The animal experiment was conducted in accordance with the regulations of the Ethics Committee for Experimental Animal Management and Animal Welfare of Institute of Materia Medica, Chinese Academy of Medical Sciences. A "drug-component-target-disease" network was established using network pharmacology, and the "component-target" sub-network related to the above energy metabolism processes was extracted by combining metabonomics results. Results revealed 79 chemical compounds and 47 potential targets of QDP involved in the regulation of energy metabolism, and identified key chemical components including ursolic acid, notoginsenoside G, ginsenoside-Rh1, and core targets such as INS, PPARG, and AKT1. The results also demonstrated the complex multi-target and multi-component relationship between QDP and HF from the perspective of energy metabolism. The molecular docking technique verified a strong interaction between some targets and chemical compounds, with affinities less than -5 kcal·mol^-1. The results of this study provide useful information for the clinical application, development, and utilization of QDP.

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.

Autoimmune hepatitis is a type of autoimmune disease and has known pathogenesis at present, which is believed to be associated with immune imbalance in the body. In inflammatory diseases, regulatory B cells (Bregs) inhibits the differentiation of CD4+ T lymphocytes into T helper 1 cells and T helper 17 cells by secreting interleukin-10 (IL-10) to inhibit inflammatory response. Patients with autoimmune hepatitis have reductions in the level of IL-10 in peripheral blood and the number and function of Bregs, which leads to the fact that Bregs cannot effectively inhibit inflammatory response, suggesting that Bregs play a certain role in the pathogenesis of autoimmune hepatitis. This article reviews the mechanism of action of Breg subsets in autoimmune hepatitis.

Objective: To optimize the prescription and preparation process of "Hugan I" Orally Disintegrating Tablets, and investigate its efficacy against acute liver injury in mice. Methods: Single factor method was used for disintegrants, lubricants, and fillers screening. Taking the appearance, hardness, friability and disintegration time of the tablets as the comprehensive evaluation index, the dosage of disintegrant, micro-silica gel and magnesium stearate was selected as the investigation factor. The Box-Behnken response surface method was used to optimize the orally disintegrating tablets. Acetaminophen (APAP, 500 mg/kg) was used to replicate acute liver injury model by one-time high-dose intragastric administration to investigate the effects of orally disintegrating tablets on the activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in serum, the content of glutathione (GSH) and malondialdehyde (MDA) and morphological changes in liver tissue. Results: The optimal prescription was as following: dry paste powder 22.00%, microcrystalline cellulose 18.00%, sorbitol 20.00%, mannitol 16.00%, Aspartame 0.50%, citric acid 0.50%, disintegration agent L-HPC 20.00%, micro-powder silica gel 2.50% and magnesium stearate 0.50%. The hardness of the orally disintegrating tablets was 4-7 kg, the mean disintegration time was about 50 s, and the mean friability was around 0.85%. Compared with the model group, there were significant differences (P < 0.01) in Biphenyl diester control group, "Hugan I" Decoction group and "Hugan I" Orally Disintegrating Tablets group, and the levels of ALT and AST in the serum of the mice were significantly decreased, The content of MDA in the liver tissue was decreased, which improved the damage of APAP to liver tissue. Conclusion: The formulation of the "Hugan I" Orally Disintegrating Tablet is feasible and easy to operate, which achieves the same effect with "Hugan I" Decoction that effectively prevent liver damage caused by acetaminophen with no significant differences.
