To the Editor： Hydatid is an endemic zoonosis disease which brings great harm to the human. It is popular in developing countries especially in North Western China where animal husbandry is the primary industry. For liver hydatid, a few cases may be associated with diaphragmatic muscle invasion, and even invasion into the chest and the right lung, which become more difficult in clinical treatment.

Background Mirizzi syndrome is often difficult to diagnose before surgery, and is often accompanied by extensive adhesions in the cystohepatic （Calot＇s） triangle and the difficulty of separating tissue can lead to bile duct injury and other intraoperative and postoperative complications. The aim of this study is to investigate minimally invasive means of treating different types of Mirizzi syndrome. Methods Fifty-four patients diagnosed with Mirizzi syndrome were enrolled between July 2004 and May 2012. The diagnosis was further refined according to the Csendes classification. Twenty-seven patients were treated with a combination of endoscopic retrograde cholangiopancreatography （ERCP）, laparoscopy, and choledochoscopy （tripartite approach group）; type I in 16 cases, type II five cases, and type III in six cases. Twenty-seven patients were treated with laparotomy （routine approach group）; type I in 19 cases, type II in six cases, and type III in two cases. The operation time, blood loss during operation, initiation of intake time of food, postoperative complications, and hospital stays were compared between two groups. Results All patients were successfully cured in surgical operation. The operation time was （49.7±27.5） minutes, blood loss during operation was （21.1±15.9） ml, initiation of intake time of food was （6.3±2.7） hours, postoperative complications were with two cases （7%, 2/27）, and hospital stay was （6.7±1.8） days in the tripartite approach group. In the routine approach group, the operation time was （85.1±20.3） minutes, blood loss during operation was （150.3±20.5） ml, initiation of intake time of food was （36.6±10.3） hours, postoperative complications were with three cases （11%, 3/27）, and hospital stay was （10.9±3.4） days. Except for postoperative complications, there were significant differences in the operation time, blood loss during operation, initiation of intake time of food, and hospital stays between two groups （P 〈0.05）.

Tumor hypoxia severely limits the therapeutic efficacy of photodynamic therapy(PDT) for solid tumors,which is highly dependent on tissue oxygen *** this study,we developed a platinum(Ⅱ)-acetylide-based metallacycle compound bearing six 1,4-dimethylnaphthalenes(DMN) groups,and controlled the photodynamic and photothermal effects of the compound by adjusting the power of 730 nm laser to achieve reversible sensitization,storage and release of 1~O_(2) within a single *** compound formed nanoparticles by self-assembly and exhibited good water solubility and *** laser irradiation,the strong spin-orbit coupling of platinum atoms in the metallacycle facilitated 1~O_(2) *** produced 1~O_(2) was captured by the DMN carriers and transported into the hypoxic tumor,where 1~O_(2) release was triggered owing to the good photothermal effect of the extended conjugation of the *** therapy,the metallacycle serving as a photosensitizer,1~O_(2) carrier,and photothermal reagent,achieved the synergistic therapy of PDT/PTT,demonstrating the versatility of the *** study proposes a new strategy to develop phototherapy agents that are suitable for hypoxic tumors.
