Objective To investigate the therapeutic effect and the immune function impacts of high intensity focused ultrasound(HIFU) for the treatment of hepatocellular carcinoma.Methods Twenty-five cases with primary liver cancer and 6 cases with metastatic liver cancer were treated with HIFU.The clinical symptoms,AFP levels,color Doppler ultrasound detection,CT and changes of T-cell subsets ( CD3 +,CD4 +,CD8 +,CD4 +/CD8 + ) were recorded before and after treatment.Results After HIFU treatment,among 31 patients,the clinical remission rate was 89.7% ( 25/29 ).AFP was decreased in 83.3% ( 15/18 ) of the patients.Color Doppler showed reduced tumor sizes and reduced or disappeared blood supply in most of the patients.CT scan displayed that the density of the target region was decreased and necrosis of the lesions occurred.The percentage of CD3 + and CD4 + cells and the ratio of CD4 +/CD8 + were significantly increased after a period of treatment( P <0.05 ).The proportion of CD8 + cells was decreased significantly after a period of treatment ( P < 0.05 ).Conclusion HIFU is an effective technique for the treatment of hepatocellular carcinoma.Meanwhile,it can improve human immune function to certain extend.

BACKGROUND:Comeal graft endothelial cell density may decline spontaneously at a super-physiological speed after penetrating keratoplasty (PKP),even if no corneal rejection happens,and this is chronic corneal allograff dysfunction (CCAD).OBJECTIVE:To investigate the effects of topical corticosteroid treatment on chronic corneal allograft dysfunction after PKP.DESIGN,TIME AND SETTING:A controlled clinical analysis was performed at the Department of Ophthalmology,Tongji Hospital,Tongji University from May 2004 to May 2009.PARTICIPANTS:A total of 54 patients (eyes) who underwent PKP were included in this study.METHODS:Tobramycin-dexamethasone eyedrops was applied 6 times per day as an initial dosage and tapered during 4 months.Thereafter,drug withdrawal group and long term group were randomly divided.Treatments were ceased in the drug withdrawal group but were continued in the long-term group with a dosage of twice per day till 12 months after surgery.MAIN OUTCOME MEASURES:Corneal graft endothelial cell density was followed up.The mean follow up pedod was 3.12±0.28years.RESULTS:The corneal graft endothelial cell density of drug withdrawal and long term groups was dramatically declined within 36 months after PKP.At every time point,the endothelial cell density was significantly decreased compared to the last follow up (all P<0.01 ).The endothelial cell density was decreased from (2 428±2.11) cells/mm~2 and (2 791±2.29) cells/mm~2 to (1 424±124) cells/mm~2 and (1 614±114) cells/mm~2 in the drug withdrawal and long-term groups,respectively.There was significant difference in endothelial cell density between the two groups no matter prior to surgery or at each time points after surgery,but the declination trends of two groups were basically the same,indicating that graft loss of endothelial cell density was not impacted by topical corticosteroid treatment after PKP (P>0.05).CONCLUSION:Chronic corneal allograft dysfunction after PKP is independent of topical corticosteroid treatment.

Objective To evaluate the clinical effects of intra-lamellar orbicularis dissecting micro-traumatic double eyelid surgery for the treatment of adolescent upper eyelid trichiasis. Methods Three cutaneous micro-incisions following intra- and sub-lamellar orbicularis dissections were performed and the deep orbieularis and suborbicularis fat pad between the intended eyelid crease and 1 mm above the eyelid margin were resected. The subcutaneous orbicularis was fixed to the exposed levator aponeurosis at the medial, center and lateral regions. For the quantitative analysis, the entire eyelid margins' eyelashes were equally divided into three sections and the eyelashes lift-up angle (LA), the body curl-up angle (BC) and the end curl-up angle (EC) were compared before and after surgery in each section, respectively. Results One hundred and fourteen eyes of 57 cases were followed up during 24-30 months. Compared to the LA before surgery and 2 years after surgery, it was changed from (26.37±9.67)° to (55.42± 10.03)° in section Ⅰ , and from (22.03±11.64)° to (50.03±10.02)° in section Ⅱ , and from (25.31±8.01)° to (64.05±8.33)° in section Ⅲ. There were no significant changes of BC and EC during following-up. Con-clusions For the adolescent upper eyelid trichiasis, the intra-lamellar orbicularis dissecting micro-trau-matic double eyelid surgery could acquire satisfactory aesthetic appearance and stable eyelashes'position at the same time.

Objective To evaluate the influence of rectal washout on the prognosis of rectal cancer after anterior resection.Methods Data of 144 patients with rectal cancer undergoing anterior resection at Chinese Academy of Medical Science Cancer Hospital between May 2006 and November 2007 were reviewed.69 patients received rectal washout and 75 patients did not.The incidences of recurrence and 5-year disease-free survival rates were compared.Data were analyzed by SPSS 13.0 software packet,using x2 and t inspection.Kaplan-Meier method was used to calculate postoperative survival rate.Results Washing sample was positive for malignant cells in 55 patients (79.7%).The incidences of recurrence were 4.6% and 6.7% in washout group and no-washout group respectively (x2 =0.368,P =0.721).The five-year disease-free survival rate was 79.7% in washout group and 74.7% in no-washout group(x2 =0.517,P =0.553).Conclusions Free malignant cells were ubiquitous in rectal lumen during anterior resection,and there was a high positive rate of cytological examine for washout sample.Rectal washout may reduce local recurrence and prolong patients' survival.

In this paper, optimization of the conditions of microwave technique in extraction process of Guizhi Fuling capsule in the condition of a pilot scale was carried out. First of all, through the single factor experiment investigation of various factors, the overall impact tendency and range of each factor were determined. Secondly, L9 (3(4)) orthogonal test optimization was used, and the contents of gallic acid in liquid, paeoniflorin, benzoic acid, cinnamic acid, benzoyl paeoniflorin, amygdalin of the liquid medicine were detected. The extraction rate and comprehensive evaluation were calculated with the extraction effect, as the judgment basis. Theoptimum extraction process of Guizhi Fuling capsule by microwave technology was as follows: the ratio of liquid to solid was 6: 1 added to drinking water, the microwave power was 6 kW, extraction time was 20 min for 3 times. The process of the three batch of amplification through verification, the results are stable, and compared with conventional water extraction has the advantages of energy saving, time saving, high efficiency advantages. The above results show the optimum extracting technology of high efficiency, stable and feasible.
