[Objective] To discuss the reasonable treatment and skil of gal bladder calculus.[Method] Select 81 cases of such patients, take their clinical data as examples for analysis foundation;and choose relative documents for evidence of theoretic analysis.[Result] 77 cases were successively operated of laparo-scope, 3 transferred for laparotomy owing to difficult anatomy of Colot triangle, 1 made probe of choledoch because of choledocholithiasis;compared with documents results, the incision length, bleeding, operaiotn time, in-hospital time and complications of laparoscope operation, transferred laparotomy in the study were similar to relative documentary reports, the differences had no statistical meaning;the intranperative bleeding, operation period, in-hopital time, complications were better than documents, the differences had statistical meaning. [Conclusion] The correct pre-operation evaluation of disease condition, operation chance and methods selection, 3 operation points were the key of successful operaiton.

Apoptosis is a spontaneous process of cell-suicide process triggered in response to physiological and pathological stress stimul, which is to regulate the developmental of body, control cell senescence, maintain a stable internal enviroment in multicellular organisms. The initial and progress of apoptosis is precisely controlled, which is a unique and complex signal system. In this review, it introduced the relationship between apoptosis and bcl-2 gene family, C-myc, tumor suppressor gene p53, Caspase protease family and Fas, and Summaries the detection methods.

Objective To explore the clinical value of real time contrast-enhanced ultrasound in diagnosis of liver localized fatty deletion and fatty infiltration which couldn't be confirmed by conventional ultrasonography. Methods Contrast-enhanced ultrasound was performed on 94 patients with liver localized diseases confirmed by baseline sonography, among them 34 patients with liver localized fatty deletion and fatty infiltration were enrolled. Results Contrast-enhanced ultrasonography didn't show apparent occupancy nidus in 34 patients. Enhancement mode of lesions was the same as liver parenchyma, which was distinctly different from liver occupancy diseases. Conclusion Real time contrast-enhanced ultrasound can display typical signs of liver localized fatty deletion and fatty infiltration and has significant value in diagnosis and differentiating diagnosis of them.

BACKGROUND: Magnesium alloy studies in orthopedic field have been carried out,and good biocompatibility has been reported.However magnesium alloys have not yet been researched in the intestine.OBJECTIVE: The biodegradable magnesium-zinc alloy samples are implanted around the rat cecum to investigate the biocompatibility in rat.METHODS: Sprague Dawley rats were randomly divided into magnesium alloy group,medical titanium group and the sham-operated group.Then magnesium-zinc alloy samples with the dimension of 5 mm × 1 mm× 1 mm were embedded in the cecum incision in the magnesium alloy group.The medical titanium was embedded in the medical titanium group,and just suture in the sham-operated group.Prior to surgery and at 7,14,21 and 28 days after operation,the serum glutamic-oxaloacetic transaminase,creatinine and magnesium ion concentration were examined in each group.X-ray film on implanted region.The pathological changes in liver,kidney and cecum were examined.RESULTS AND CONCLUSION: There were no significant differences in serum glutamic-oxaloacetic transaminase,creatinine and magnesium ion concentrations among each group(P > 0.05).Magnesium-zinc alloy degraded gradually during 28 days.The pathology of liver,kidney and cecum was normal.Results suggested that magnesium-zinc alloy had no obvious effect on the cecum.The degradation time to play a fixed function of time was longer than the intestinal healing time,with good biocompatibility.Magnesium-zinc alloy can be used as anastomotic nail for stomach intestine anastomat.

Objective To investigate the changes of lymphocyte subsets before and after the treatment with operation and chemotherapy in patients with breast cancer.Methods Using cytometer to measure lymphocyte subsets of CD3+,CD4+, CD8+,CD4+/CD8+ and NK of 25 breast cancer patients before and after treatment.The all 25 patients were treated with operation and chemotherapy after pathological diagnosis.The article compared the figures of T cell subsets before and after treatment.Results Compared with before operation and chemotherapy,the CD8+ statistically decreased after 1~3 months of treatment (t=2.57),and NK statistically increased after 3~6 (t=-2.23).After 6 months of treatment,the patients’ CD3+(t=-2.25),CD4+(t=-2.07)were statistically lower and NK (t=-3.56)was statistically higher.There was no significant difference for other items.Conclusion Lymphocyte subsets test against breast cancer patients can reflect immuni-ty level at a certain level during treatment.But how to explain the figures in different stage against treatment effectiveness and prognosis need further research.

Background Erythropoietin (EPO) was proved to be express in hematopoietic tissue and nervous system and play the effects of stimulating blood cell production and protecting nervous tissue.Researches showed that EPO is expressed in the embryon brain of animal.However,whether EPO exist in nervous-derived retina and its action on retina with the development is concerned. Objective This research was to investigate the expression of EPO during the embryonic development period of rat retina and explore the role of EPO in retina development process.Methods Clean Wistar rats with pregnancy for 12 days,16 days and 20 days were collected,and the embryonic 12-day rats (E12 d,5 rats),embryonic 16-day rats (E16 d,5 rats) and embryonic 20-day rats ( E20 d,5 rats) were obtained by caesarean operation,and 5 12-month W istar rats were used as controls.The rats were sacrificed by cervical dislocation and the retinal sections were prepared in the different-embryo-phase (12 d,16 d,20d) and growth phase.The expression of EPO protein and mRNA in rat retina was detected by immunohistochemistry and reverse transcription-polymerase chain reaction (RT-PCR),respectively.The feed and use of the animals followed the Regulation for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results EPO was positively expressed in the cytoplasm and nuclei in the neuroepithelial layer and pigment epithelium of every-embryo-phase rats but only in retinal ganglion cell layer in 12-month-old rats.The gray scale values of EPO expression in retina were 105.55±10.35,99.35± 8.71,83.27± 7.84and 30.30± 3.80 in E12 d rats,E16 d rats,E20 d rats and 12-month-old rats respectively with a statistically significant difference (F=76.13,P<0.01 ).RT-PCR revealed that the relative values of EPO mRNA expression in retina were 0.876±0.10,0.861 ±0.09 and 0.256±0.03 in E16 d rats,E20 d rats and 12-month-old rats respectively,presenting a elevated value in embryonic rats compared with adult rats ( P =0.00).Gel imaging deletion showed that the A value of EPO amplification products was highest in E16 d rats and lowest in adult rats.Conclusions The expression of EPO appears a high to low fashion during the embryonic development of Wistar rats,which is closely associated with the developing procedure of retina.

Objective To investigate the preventive effects of anti-viral therapy in combination with transcatheter arteria chemoembolization (TACE) on recurrence of HBV-related hepatocellular carcinoma (HCC) after operation. Methods According to selection standards, 49 patients treated in this hospital from January 2003 to June 2009 were enrolled in this study and divided into a control group and combined group.The cumulative tumor-free survival rate, cumulative survival rate, the 1-, 2- and 3-year recurrence rates and cumulative recurrence rates were determined in all the patients and compared between the 2 groups. Results The cumulative tumor-free survival rate and cumulative survival rate were significantly higher in the combined group than in the control group (P=0. 019, 0. 008). The 1-, 2-, and 3-recurrence rates were 24% vs. 38.9%, 28% vs. 33.3%, and 28% vs. 22.2% in the combined group and control group, respectively. The 1-, 2-, and 3-year cumulative recurrence rates were 24% vs. 38. 9%, 52% vs. 72. 2%, and 80% vs.94. 4% in the combined group and control group, respectively. Conclusion Anti-viral therapy in combination with TACE can exert significant preventive effects on recurrence of HBV-related HCC after operation.
