Objective To discuss the surgical skills and clinical value of laparoscopic splenectomy with a safe approach to the splenic hilum through first mobilizing the lower pole of the spleen.Methods A total of 88 patients with hypersplenism secondary to liver cirrhosis who underwent laparoscopic splenectomy in our department from September 2015 to September 2016 were selected into this study.And these patients were divided into two groups based on whether to take the safe approach to the splenic hilum through first mobilizing the lower pole of the spleen in laparoscopic splenectomy.The control group included 40 cases who underwent the traditonal laparoscopic splenectomy,while the observation group included 48 cases who took the safe approach to the splenic hilum through first mobilizing the lower pole of the spleen in laparoscopic splenectomy.The clinical data were collected retrospectively by medical clinical records review.Results There was no mortality occurred in this study.The blood loss of the observation group was (247.50±135.89)mL,which was obviously lower than (361.75±144.43)mL of the control group,and the difference was statistically significant (P<0.05).The operation time of the two groups were (194.69±47.99)min and (232.75±45.26)min respectively,and the difference was statistically significant (P<0.05).No significant difference was found in terms of rate of conversion to laparotomy,rate of intraoperative blood transfusion,postoperative hospital stay and complications (P>0.05).Conclusion It is very crucial for a safe approach to the splenic hilum through first mobilizing the lower pole of the spleen to establish a tunnel behind the splenic hilum in laparoscopic splenectomy.It is safe and feasible to perform a safe approach to the splenic hilum through first mobilizing the lower pole of the spleen in laparoscopic splenectomy.The technique is generalized in clinics,especially for freshmen.

Objective To investigate the clinical characteristic and risk factors of corticosteriod-induced ocular hypertension after vitreoretinal surgery.Methods Retrospective analysis was made based on the clinical data of 866 patients,including 126 corticosteriod-induced ocular hypertension(89 male,37 female,age range 9-70 years old) after vitreoretinal surgery during May 2002 to May 2005.Results All cases used glucocorticoid locally or systemically.Multi-variance logistic analysis showed that male,complicated vitreoretinal surgery,longer hospital stay,therapeutic duration with glucocorticoid,cataracta were the independent predictive factors,while myopia,hypertension,diabetes were not closely related to corticosteroid-induced ocular hypertension.Conclusion The incidence of corticosteriod-induced ocular hypertension after vitreoretinal surgery was 14.55%.The important factor leading to ocular hypertension is long-term application of glucocorticoid.

1. Fifty upper limbs of adult cadavers were dissected under an operating microscope.2. The ramus superficialis of the radial nerve is about 180 mm long, and springs from the radial nerve at a level about 16 mm below the medial epicondyle of the humerus. As the radial artery, it can be divided into superficial and deep parts by the overlapping of musculus brachioradialis. The junction between the two parts corresponds to a plane which divides the forearm into upper 2/3 and lower 1/3. The width of the ramus superficialis increases gradually as it runs downwards, and its cross section looks elliptical distally and somewhat circular proximally. Each of the two parts of the ramus superficialis receives 1～4 arteries from the lateral cutaneous arteries or muscular branches of the radial artery. Measurements were made to determine the position of the origin of these arteries.3. The nervus cutaneous antebrachii lateralis divides into two branches in the forearm, and receives 2～8 arteries mainly from the lateral cutaneous branches of the radial artery. It usually gives a branch communicating with the ramus superficialis of the radial nerve. The nervus cutaneous antebrachii lateralis can be found easily at the point just 5～6 mm lateral to the junction of the superficial and deep parts of the radial artery.4. The applied anatomy of the vascular pedicle nerve graft was discussed.

BackgroundOcular melanoma is a malignant tumor with a poor prognosis.To study its mode of pathogenesis and development is helpful for early diagnosis and treatment and improving prognosis. Objective This study was to analyze the location and pathological types of ocular melanoma,and explore the relationship of pathological types with prognosis of ocular malignant melanoma. Methods 110 clinical data and specimens of ocular melanoma were collected at West China Hospital,China.The specimens were examined by hematoxylin & eosin staining,immunochemistry and studying their ultrastructure.The growth location,histological classification,and their relationship with prognosis were analyzed and discussed.The clinicopathological records of the 1 l0 cases with ocular region malignant melanoma treated from January 1980 to December 2007 were analyzed.Results The primary locations of the tumors with respect to the tissue type were:66 cases in the uvea (60.00％ ),27 cases in the ocular surface tissue (24.55％),8 cases in the secondary lesion of orbit cavity (7.27％),7 cases on the eyelid skin (6.36％),and 2 cases in the lacrimal sac ( 1.82％ ).The neoplasm was classified according to pathological types:spindle-cell A type in 31 cases (28.18％ ),spindle-cell B type in 31 cases (28.18％),mixed-cell type in 25 cases (22.73％),epithelioid-cell type in 17 cases ( 15.46％ ) and other type in 6 cases (5.45％).The notability of diffusion or recurrence rate of the 5 pathological types showed statistical significance (x2 =14.463,P =0.006 ),and the rank in decending order was:other type,epithelioid-cell type,mixed-cell type,spindle-cell B type and spindle-cell A type.The clinical manifestations of ocular melanoma were dependent upon the lesion position without specificity.ConclusionsThe majority of the ocular malignant melanoma appears in the uvea and ocular surface tissue,and its common pathological types were spindle-cell type followed by mixed-cell type,epithelioid-cell type and other type.The highest recurrence rate is in other type of ocular malignant melanoma.Ophthalmologist should be aware of the clinical manifestation of ocular malignant melanoma.

Objective To observe the characteristics of vertical cast-off bloodstain pattern by different hitting-tools. Methods The regular hitting tools, a kitchen knife, a dirk, a plane set-hammer and an iron pipe, were selected. At a distance of 30 cmaway fromthe wall, the hitting tool with 5 mL fresh chick-en blood made the cast-off bloodstain fromtop to bottom. Then the holistic distribution characteristics ( length , width and density ) of cast-off bloodstain and morphology characteristics ( length , width and contact angle) of first single cast-off bloodstain were analyzed. Results The distribution length of cast-off bloodstain formed by dirk was minimum( P<0 .05 ) . The distribution width of cast-off bloodstain formed by kitchen knife was minimum(P<0.05). Except the pair of kitchen knife and plane set-hammer, the distribution density between each two tools had statistical differences (P<0.05). The length of first single cast-off bloodstain formed by plane set-hammer was longest compared (P<0.05). The width of first single cast-off bloodstain had statistical differences between kitchen knife and plane set-hammer, and between dirk and plane set-hammer (P<0.05). Conclusion The type of hitting tool could be inferred by the specific characteristics of cast-off bloodstain pattern formed by every specific type of hitting tool in crime scene.

Objective To study the clinical features of renal angiomyolipomas with tuberous sclerosis and to improve the recognization of this disease. Methods The diagnosis and treatment of 4 cases of tuberous sclerosis with bilateral and multiple renal angiomyolipomas were reviewed.The age range was 17 to 44 years,two of them were men.One patient presented with the classic triad:facial angiofibroma,seizures,and mental retardation.Facial angiofibroma occurred in three and seizures were found in two,three patients showed multiple extrarenal organ involvement including liver,spleen and bone.Brain CT revealed classical calcified cortical tuber and(or) subependymal nodule in three cases. Results The diagnosis of renal angiomyolipomas in three cases was affirmed on CT scan.However,the giant renal angiomyolipomas in one case can not be diagnosed from renal CT scan which did not demonstrate characteristic fatty tissue whereas the diagonsis was confirmed by ultrasound-guided right renal tumor biopsy and subsequent right nephrectomy for the large leisions.Regular monitoring of one patient was adopted for his mild symptomatic small renal leisions,the other two with hemorrhage in renal angiomyolipomas were reluctant to aggressive treatment and underwent conservative therapy.Follow-up ranged 6 to 36 months, none had recurrent symptoms and no significant growth of renal lesions was observed. Conclusions CT may not be pathognomonic for renal angiomyolipomas associated with tuberous sclerosis,needle biopsy may be needed to exclude renal carcinoma.The choice of treatment is based on tumor size distribution pattern,progression,and associated symptoms.
