Objective To study the protective effects of pre-storing glycogen on warm ischemia reperfusion injury during partial hepatectomy. Methods Thirty-eight patients were randomly divided into a trial group (n=19) and a control group (n=19). In the trial group, patients were given high concentration glucose intravenously during the 24 hours before the operation. The hepatic lesion was resected after portal triad clamping in the two groups. Liver function of all patients was measured before the operation and the first and fifth days after the operation. Normal hepatic tissue was biopsied to measured hepatic tissue glycogen contents before the operation and the change of superoxide dismutase (SOD) at the point of pre-ischemia, post-ischemia, and reperfusion 2 hour. Bcl-2 mRNA, a well known anti-apoptotic factor, was also detected using quantitative polymerase chain reaction. Results The hepatic tissue glycogen content of the trial group was significantly higher than that of the control group before the operation (Plt;0.01). Liver function of the trial group was significantly better than that of the control group on the first and fifth day after operation (Plt;0.05). There was significant difference in SOD activity between the two groups at the end of hepatic vascular occlusion and at the point of 2-hour reperfusion (Plt;0.05). Furthermore Bcl-2 mRNA expression of the trial group was notably up-regulated at the point of 2-hour reperfusion compared to the control group. Conclusion Pre-store storing glycogen might protect liver ischemia reperfusion injury caused by hepatic vascular occlusion during partial hepatectomy. The potential mechanism might be that pre-storing glycogen enhances Bcl-2 expression.

To evaluate the biological tolerance of the human liver to prolonged warm ischemia, 20 patients who underwent liver resections with hepatic inflow occlusion are reported. Biopsy of liver were performed during and after consecutive periods of hepatic ischemia, and speciments were observed under light and electron microscope. The results showed that hepatic vascular occlusion for ＜30 min, resulted in atotissular temporary but reversible pathologic and ultrastructural changes in liver, even patients with liver cirrhosis had better recovery from the operation when the hepatic ischemia was lengthen up to 40 min.
Thirty-six partial hepatectomies for patients with symptomatic intrahepatic stones is reported.Partial liver resection should be done when the liver containing strictrue(s),dilated ducts and stones.Meanwhile,additional procedures should be performed togather with partial hepatectomy,i,e,common duct exploration and drainage,cholangiotomy and cholangioplanty,and cholangeoenterostomy,according to the location of stones and ductal strictures.Postoperative long-term follow-up in this series showed that the results of 86.2% of patients were satiffactory.Partial hepatectomy can be considered as a better treatment of choice for the stones confined to one segment or lobe of liver or combined with multiple strictures of ducts.
Objective To investigate the advance in surgical treatment of inferior pole fracture of patella and to explore the existing problems and further research directions. Methods Domestic and foreign l iterature in recent years on patella fracture was extensively reviewed, the surgical treatment of inferior pole fracture of patella was summarized by combining the research findings with cl inical experience. Results The surgical treatment of inferior pole of patella fractures included retaining the integrity of the patella and partial patellectomy of inferior pole of patella and extending knee installationreconstruction. There were kinds of ways to retain the integrity of the patella, such as circular wire fixation, tension bandfixation, NiTi-patella concentrotor fixation, basket plate fixation, reforming McLaughl in way and polydioxanone suture netfixation; the latter category is partial patellectomy and extensor device reconstruction. Every surgical way had its advantages and l imitations. Conclusion Most studies tend to retain the integrity of the patella, but some researches have shown that partial resection of inferior pole of patella had no significant effect on knee function. It is important to obtain the security excisional range and elongation range postoperative by experiment for regulating the treatment of comminuted fractures of inferior pole of patella.
【Abstract】 Objective To compare the short-term effects of arthroscopic partial meniscectomy in treating medial versuslateral meniscus injuries. Methods From January 2003 to January 2006, 207 patients with meniscus injury(without intraarticularligament injury) underwent arthroscopic partial meniscectomy. The medial meniscus injury group included 115 cases, 50males and 65 females; aged 14 to 78 years(mean 46.9 years); 66 left knees and 49 right knees. Twenty-six cases had injury histories,the delayed time from injury to surgery ranged from 6 d to 6 months (mean 2.1 months). The lateral meniscus injury group included92 cases, 18 males and 74 females; aged 16 to 62 years (mean 41.1 years); 57 left knees and 35 right knees. Twenty-four caseshad injury histories, the delayed time from injury to surgery ranged from 9 d to 6 months (mean 1.9 months). Lysholm score systemwas applied and the scors of pre- and post-operation and were compared between two groups. Results The period of followupranged from 12 to 45 months (mean 31.5 months). In medial meniscus injury group and lateral meniscus injury roup, theLysholm score increased from 61.3±16.9 and 57.4±17.6 preoperation to 95.0±7.9 and 93.3±7.4 postoperation respectively. Therewas statistically significant difference between preoperation and postoperation (P lt; 0.01), and there was no statistically significantdifference between two groups（P gt; 0.05）. The excellent and good rates for function of knee joint were 97.39% (excellent in 107cases, good in 5 cases and fair in 3 cases) in medial meniscus injury group and 100%(excellent in 80 cases and good in 12 cases)in lateral meniscus injury group. Conclusion Arthroscopic partial meniscectomy is a safe and effective treatment for meniscusinjury, there is no diference in short-term effects in treating medial versus lateral meniscus injuries.
Objective To evaluate the effect of the combined method of l iposuction and semicircular periareolar incision glandular organ partial resection in the treatment of gynecomastia. Methods From June 2004 to June 2006, 40 patients, aged 11-41 years old, were treated, with no-nodule (n=10), nodule (n=22) and female-breast-l ike with nodules (n=8). Three patients were unilateral and 37 ones were bilateral. The levels of serum prolactin, luteinizing hormone, foll icle stimulating hormone, estradiol, testosterone and cortisol were normal in 38 patients, while in the other 2 patients, the levels ofserum prolactin, luteinizing hormone, foll icle stimulating hormone and estradiol were higher than normal, and the testosterone level was lower. Li posuction alone was performed in 10 no-nodule patients (lei po-type), and combined l i posuction and semicircular periareolar incision glandular organ partial resection were conducted in the other 30 patients (lei po-glandular type). Results Except for 2 cases in which hematoma and a small amount of effusion were found on the first and second day postoperatively and then obtained heal ing by first intention right after hematoma removal in time, all the other patients’ incisions obtained heal ing by first intention. Ni pple numbness occurred in 3 cases on the first day postoperatively and no special treatment was conducted. There was still nipple hypesthesia in these 3 cases after 6-month follow-up. There were no compl ications such as hematoma, effusion, nipple and mammary areola necrosis, and nipple hypesthesia in other patients. All the 40 patients were followed up for 6-24 months (13 months on average). They were satisfied with their chest figures and no recurrence was observed. Conclusion The combined method of l iposuction and semicircular periareolar incision glandular organ partial resection in the treatment of gynecomastia has many advantages, such as safe, micro-scars, natural and beautiful male breast figures as well as high patients’ satisfaction.

Methods: Laparoscopic subtotal cholecystectomy was performed when the cystic duct cannot be identified safely, such as empyema cholecystitis, Mirris syndrome, frozen Calot’triangle, shrunken gallbladder. The operation consists of resecting the anterior wall of the gallbladder, removing all stones, and placing a large drain. 41 patients who underwent a laparoscopic subtotal cholecystectomy between 1 January 2003 and 31 October 2008 were retrospectively analyzed. Results: Fortyone cases of complex laparoscopic cholecystectomy were performed. 1 cases in which were changed to open cholecystectomy. Operating time was 45145 min, average (57.42±19.41) min. 1 cases were reoperated because of the bile leak. Hospital stays were 27 days. Conclusion: Laparoscopic subtotal cholecystectomy is a viable procedure during cholecystectomy in which Calot’s triangle cannot be safely dissected. It may simplify the operation and decrease the risk in complicated cholecystectomy and averts the need for a laparotomy.
