Objective To evaluate the effects of different surgical treatments on severe polycystic liver disease (SPLD). Methods A total of 22 patients with SPLD were surgically treated in our Department from December 1989 to July 1999. Of the patients, 5 were treated with the partial hepatic resection in combination with cyst fenestration (group A), 7 with laparotomic fenestration (group B), 4 with laparoscopic fenestration (group C) and 6 with puncture under the guidance of ultrasonography B (group D). The surgical outcome and long term follow up results were retrospectively analyzed. Results After the treatments, all the patients experienced immediate relief of symptoms. However, the follow up for an average of 3 years showed that 10 patients developed recurrence of the disease. The recurring rates were 0, 28.5%, 65.5% and 100% in groups A, B, C and D, respectively. Conclusions The approach of partial hepatic resection in combination with cyst fenestration is the most effective treatment for SPLD. Laparoscopic fenestration may not be an appropriate surgical way for treatment of SPLD.

Objective To study the effect of mitochondrial permeability transition(MPT) after ischemia/reperfusion(I/R), and to find the relationship between MPT and apoptosis of hepatocytes in rats. Methods SD rats were divided into three groups:sham operation group, I/R group, and I/R+CsA group. A model of hepatic I/R in rats was made according to the method of Nauta. Active caspase-3 in cytoplasm was examined by immunohistochemistry, and the content of cytochrome C protein was evaluated by Western blotting. The incidence of apoptic hepatocytes was determined by TUNEL method. Cyclosporine A(10 mg?kg -1?d -1) was used as an inhibitor of MPT owing to its inhibitive effect on mitochondrial permeability transition pore(PT pore), and the influences of CsA were analyzed. Results Pretreated with CsA ameliorated injury after reperfusion. The number of apoptotic liver cells was decreased. CsA significantly prevented the release of cytochrome C from mitochondria, demonstrating its effect on MPT through preventing PT pore from opening. Conclusion MPT may play a key role in the apoptosis of liver cell after I/R. CsA, a powerful inhibitor of PT pore, is capable of abating the effect of MPT, reducing the release of cytochrome C, retarding the activation of caspase-3 and hence ameliorates apoptosis of hepatocytes following I/R procedure.

Objective To study the effect of hypothermia on cerebral mitochondrial respiratory function and ultrastructure after traumatic brain injury(TBI). Methods Sprague-Dawley rats were subjected to moderate brain injury by using lateral fluid-percussion(LFP)and randomly divided into sham operation group,normothermic TBI group(rectal temperature for 36-37℃)and hypothermic TBI group(rectal temperature for 31-32℃ lasting for two hours).The ipsilateral brains were dissected and homogenized brain tissues were extracted to obtain mitochondfia by density-centrifugation and speed-centrifugation at 2,24 hours and at days 3 and 7 after TBI.The mitochondrial uhrastructure was studied by electron microscope.The indices of respiratory control rate(RCR)and P/O ratio of mitochondrial respiratory function were measured after oxygen consumption was determined with a Clark-type electrode.Results The mitochondrial uhrastructure of normothermic TBI group was damaged severely while that of hypothermic TBI group kept relatively integrated.The RCR and P/O ratio were markedly decreased two hours after TBI and reached the lowest level at the 24th hour(P＜0.01).At day 7,RCR kept at a lower level compared with sham operation group but P/O ratio recovered to normal.Change of RCR was similar in hypothermie TBI group and normothermic TBI group.However,RCR of the hypothermic TBI group was significantly higher than that of the normothermic TBI group within three days after TBI.In the meantime,P/O ratio recovered to normal three days after TBI. Conclusion Hypothermia can improve cerebral mitochondrial respiratory function and protect the mitochondrial structure after TBI.

Objective To investigate the effect of immediate breast construction using prosthesi after nipple-areola-sparing mastectomy.Methods The immediate breast construction using prosthesi after nippleareola-sparing mastectomy was performed in 26 cases with breast cancer from January 2008 to December 2011 in Jiangsu Cancer Hospital.The postoperative cosmetic results and the complications were observed.The therapeutic effects were followed up.Results All operations were successful.The s,uperior rate of cosmetic result after one month according to JCRT was 88.5 ％ (23/26).No severe complication was found.After a median follow-up of 26 months (range 3-48 months),there was no recurrence and metastasis.Conclusion The immediate breast construction using prosthesi after nipple-areola-sparing mastectomy is maneuverable with satisfactory aesthetic result and the clinical effect,which deserves the further clinical application.

Objective To explore the change of serum HER2/neu concentration during neoadjuvant chemotherapy for HER2-overexpressed breast cancer and its correlation with the response to the neoadjuvant chemotherapy.Methods The concentration of the serum HER2/neu in 78 cases of HER2-overexpressed advanced breast cancer treated with neoadjuvant chemotherapy were detected with enzyme-linked immunosordent assay(ELISA).The relationship between the serum HER2/neu concentration and the response of neoadjuvant chemotherapy was analyzed.Results The serum HER2/neu concentration of befor and after neoadjuvant chemotherapy was 18.6 ± 10.0ng/ml,11.6 ± 6.lng/ml respectively.The serum HER2/neu concentration decreased significantly(P ＜ 0.001).The response of neoadjuvant chemotherapy was correlated with the change of the serum HER2/neu concentration.The pathologic complete response was correlated with the serum HER2/neu concentration of prechemotherapy and the change of the serum HER2/neu concentration.Conclusion The change of serum HER2/neu concentration may serve as a marker predicting the response of neoadjuvant chemotherapy in HER2-overexpressed breast cancer.

Objective To investigate the compliance with endocrine therapy(ET) and assess the factors associated with treatment accuracy for breast cancer.Methods 379 patients with hormone receptor-positive breast cancer undergoing complete treatment from Jun.2006 to Jun.2008 in Jiangsu Cancer Hospital were followed up.Factors related to compliance were analyzed.Results Among the 322 (85.0％) patients successfully interviewed,15 (4.7％) patients did not receive ET,43 (13.4％) patients stopped taking drugs after discharge,14 (4.3％)patients had intermittent ET,and the rest 250 patients obeyed 5-year oral ET regularly.The treatment accuracy was 77.6％ (250/332).We found that majority of withdraw occurred within 2 months and within 2 years,accounting for 39.5％ and 48.8％,respectively.Job and education status were relevant to these patients.Moreover,too much concern of adverse drug effects and difficulty of long-term medication were the main reasons to noncompliance.Conclusions ET is effective in hormone receptor-positive breast cancer patients and has been used as a conventional therapy.However,due to the long therapeutic period and lack of medical supervision after discharge,its treatment accuracy and compliances are becoming low,resulting in decreased efficiency.It is therefore necessary to investigate such patients' management to improve the compliance and treatment accuracy of ET.

Objective To summarize our experience on diagnosis and treatment of bilateral primary breast cancer (BPBC). Methods Clinicopathologic records, including clinical manifestations, diagnosis and immunohistochemical expressions of 16 patients with BPBC, treated from 2001 to 2009 in Jiangsu Provincial Cancer Hospital, were analyzed retrospectively. Results The 16 patients with BPBC accounted for 0.47% of all patients diagnosed as malignant tumors of breast during the same period in our hospital. All of the 16 patients were women, with the median age of 53 years (ranged 41-69 years). 7 patients were in bilateral synchronous breast cancer (BSBC), with the median age 47 years (ranged 41-54 years), among whom 5 patients got BSBC just before menopause. 9 patients were in bilateral asynchronous breast cancer (BABC), with the median age 58 years (ranged 43-69 years), among whom 1 patient got BABC before menopause. The median interval between the first and second breast carcinoma of BABC was 52 months (ranged 14-196 months). Conclusions Compared with BABC, the occurrence age of the patients with BSBC was smaller. BABC was more common in premenopausal women. The interval time of BABC was irregular. The active follow-up after the occurrence of contralateral breast cancer and endocrine therapy for estrogen receptor-positive patients were recommended.
