Objective To investigate the types of ultrasonographic appearance of post-hepatectomy in operative position. Methods The data about operative manner,operative position, type of plugger in residul cavitity of 176 cases who underwent hepatic operation,were collected. Their ultrasonographic findings of post-operative liver in operative position in different phrases after operation were analyzed retrospectively. Results The main appearance was: ① Absence of partial hepatic lobe or hepatic segment; ② anechoic area with thin wall or mixed mass in operative position; ③ conformation of irregular high-echo conglomeration in operative position, irregular wall thickeness and inhomogenous internal echoes appeared in anechoic area and mixed mass in operative position, color Doppler twinking artifact appeared around some plugger and residual cavity which made by curettage and aspiration technique with time passing by. Conclusions Ultrasonographic appearance of post-hepatectomy in operative position varies with different operative manner, operative position, resected area, and Absence or existence of plugger in residual cavity, different type of plugger in residual cavity.

Objective To study the possibility of the exposed therapy of the male's perineum after operation.Methods 450 male patients with perineum surgical operation were chosen,250 among whom were adopted the exposed therapy ,200 were adopted the traditional tie-up therapy after the operation.Calculation with the statistic software SPSS 17.0 were adopted to observe the wound germ infection and heal circumstance,to statisfy the first grade heal rate and the wound germ infection rate.x2 examinations were used, too.Results The rate of the first grades healing of the exposed therapy group was obviously higher than the tie-up therapy.There was obvious difference.(x2 = 12.2,P <0.01).The rate of the germ infection of the exposed therapy set was closed to that of the tie-up therapy without obvious difference(x2 =0.06 ,P >0.05 ).Conclusion The rate of the wound germ infection would not increase if adopted the exposed therapy of the male's perineum after operation and the rate of the wound first grade heals leads to an obvious exaltation.

ObjectiveTo study changes of bone measured with quantitative ultrasound (QUS) in women of Guangzhou area and provide scientific basis for prevention and treatment of osteoporosis (OP).MethodsCalcaneus measurement was done with QUS in 647 women of Guangzhou area, and measurement data was analyzed.ResultsIn menopause and aged women, broadband ultrasound attenuation (BUA) showed a significantly decrease (P<0.01), whereas it decreased only slightly in early postmenopausal women (P>0.05). After the peak of BMD, speed of sound (SOS) showed a stepwise decline, and significantly decrease in menopause (P<0.01), but not significant over eighties (P>0.05). In contrast, stiffness index (STI) significantly decreased from the menopause, and it was a better indicator than BUA or SOS.ConclusionQUS can not only test bone mass but also assess microarchitecture, and it is nonradioactive, cheaper, easier to use, and may play a important role in diagnosis of osteoporosis and women and senile health.

Objective To examine the serum high-sensitivity C-reactive protein(hs-CRP)levels in subjects with type 2 diabetic mellitus(DM)or DM accompanied by cerebral infarction(DM+CI),and the relationship be- tween the serum high-sensitivity C-reactive protein(hs-CRP)levels,and to investigate risk factors of cerebral infarc- tion in patients with type 2 diabetic mellitus.Methods The serum high-sensitivity C-reactive protein(hs-CRP)lev- els were measured in 50 DM patients,50 DM+CI patients and 30 healthy controls by ultra-sensitive immunoassay. hs-CRP values and its relationship with cerebral infarction in patients with type 2 diabetic mellitus and other factors, such as age,BMI,TG,etc,were analyzed.Results Univariate analysis revealed significant differences in hs-CRP concentrations between controls[(0.73?0.46)mg/L]and subjects with DM[(2.26?1.38)mg/L],or subjects with DM+CI[(3.82?2.67)mg/L](P

Purpose To investigate the clinicopathologic features and immunophenotype as well as its association with EBV infection of lymphoepithelioma-like gastric carcinoma (LLGC). Methods The clinical pathological data were reviewed, morphological changes were observed and immunohistochemical staining was done in 6 cases of LLGC. The expression of EBV-encoded small RNA ( EBER) in the 6 cases of LLGC were carried out by in situ hybridization. Results All of the six patients were male, the age was arranged 47 to 68 years, with mean of 55 years. All of the six cases, the lesions were located in gastric body. Microscopically, the undifferentiated carcinoma cells were arranged in cords and nests, scattering in the lymphoid-rich stroma, occasionally poor development tubular struc-tures were seen in the near surface of mucosa. Lymphoid follicles could be seen with lack of fibrous tissues reaction in the tumor stro-ma. Immunohistochemical staining and in situ hybridization showed the tumor cells were diffusely positive for CKpan, CK19, CEA and EBER, but negative to CK7, CK20, CK5/6 and LMP1; interstitial lymphocytes expressed CD3 or CD20, while lost expression of EBER. Follow-up for 6-57 months, all of the 6 patients were survived without tumor. Conclusions The LLGC is a rare and unique subtype of gastric carcinoma with good prognosis, which is often associated with EBV infection.
