AIM: To study the effect of garlicin on protecting nonalcoholic fat liver in rats induced by high fat diet and explore the pathogenesis involved. METHODS: According to the dosage of garlicin and diet, fifty SD rats were randomly divided into five equal groups: normal control group, model control group and garlicin (10, 20, 30 mg/kg) groups. Apart from the rats in normal control group, the rats were all fed with high fat and high cholesterol diet. After 12 weeks, the levels of serum endotoxin (ETX), total cholesterols (TC), triglyceride (TG), superoxide dismutase (SOD), malondialdehyde (MDA), transaminase and free fatty acids (FFA) were detected. The levels of MDA, SOD, glutathione hormone (GSH) in hepatic tissue were also detected. Then the features of live pathology were observed. RESULTS: The levels of ETX, TC and TG in garlicin groups were significantly lower than those in model control group (P

OBJECTIVETo summarize the clinical manifestation and diagnosis of ganglioneuroma in spine and investigate the clinical effect of surgical treatment.
METHODSThe clinical data of 6 patients underwent a surgery for ganglioneuroma in spine from January 2008 to January 2015 were retrospectively analyzed. There were 4 males and 2 females, aged from 2 to 63 years old with an average of 34.6 years. The courses of disease were from 3 days to 17 years. Five patients complicated with superficial hypesthesia in correlative level of tumor, and the muscle strength under tumor plane had decreased at different levels, with the strength of grade II-IV. Two cases complicated with hypermyotonia and positive bilateral Hoffmann's and Babinski sign. Five cases were sporadic lesion in correlative spinal canal and one case complicated with the giant occupying lesion in thoracic cavity.
RESULTSSix operations had been performed including 5 en bloc and 1 subtotal resection. Postoperative pathological results showed tumor cells scattered or fasciculated inserted into Schwann cells in the stroma. In 2 patients complicated with radiculalgia before operation, 1 case was relieved and 1 was invariant after operation. All 4 patients with preoperative dyscinesia in the limbs obtained improvement after operation. All the patients were followed up from 0.3 to 6.8 years with an average of 2.5 years. At the final follow-up, according to ASIA grade, 5 cases were good and 1 case was invariant. During the follow-up, only 1 patient experienced chemoradiation because of merging ganglioneuroblastoma and receiving subtotal resection. No recurrence in other 5 cases.
CONCLUSIONGanglioneuroma is a benign and rare tumors in spine. Clinically, radicular pain and sensory-motor disorders are the main manifestations. Its diagnosis depends on pathological examination. Prognosis of surgical treatment is good.

Background and purpose: BRCA1 and BRCA2 mutation carriers have a high lifetime risk of developing breast and ovarian cancer. Through genetic counseling, mutation carriers can take the appropriate measures to reduce such cancer risk. At present, almost all related studies were conducted in Caucasian, while, the studies in Chinese population were rare. This study aimed to investigate the risk of breast cancer in BRCA1 and BRCA2 mutation carriers in Chinese Han population. Methods:Twenty unrelated families with BRCA1 or BRCA2 mutations were re-viewed. Kaplan-Meier analyses were used to estimate the cumulative risks of unilateral breast cancer and contralateral breast cancer for female BRCA1 and BRCA2 mutation carriers. Results:Breast cancer risk to 70 years (penetrance) was 67.2%(sx 0.100) for BRCA1 and 76.8%(sx 0.079) for BRCA2, respectively. Different from BRCA1 mutation carriers, the cumulative incidence of breast cancer in BRCA2 mutation carriers remained increasing after 70 years, reaching 93.1%at age 80. The 10-and 20-year risk for contralateral breast cancer was 19.4%(sx 0.089) and 50.3%(sx 0.155) for BRCA1/2 mutation carriers. Conclusion:BRCA1 and BRCA2 mutation carriers in Chinese Han population have a high risk of developing breast cancer. Thus, it has great clinical signiifcance to test mutations in BRCA1/2 genes in Chinese high-risk population.

Background and purpose:Perioperative anesthetic management is thought to be critical to the success of free flap breast reconstruction. The purpose of this study was to discuss intraoperative fluid, hemodynamic and temperature management in patients undergoing deep inferior epigastric perforator (DIEP) flap breast reconstruction.Methods:From Jun. 2011 to Dec. 2015, 126 patients underwent DIEP lfap breast reconstruction. Postoperative complications were reviewed. Intraoperative fluid infusion rate was analyzed. Mean arterial blood pressure (MAP) and core temperature were measured before induction (T0), after lfap elevation but before lfap transfer (T1), 15 min after flap revascularization (T2), and at the end of surgery (T3).Results:Nine patients developed flap compromised: 7 were salvaged and 2 failed. The mean intraoperative lfuid infusion rate was (5.44±1.66) (mL?kg-1)/h. MAP at T0, T1, T2 and T3 were (87.45±8.90), (74.19±8.63), (74.60±8.71) and (79.62±7.88) mmHg, respectively. Core temperature at T0, T1, T2 and T3 were (36.69±0.14), (36.36±0.18), (36.27±0.14) and (36.21±0.15)℃, respectively. Conclusion:Standard practice focusing on intraoperative lfuid management, hemodynamic adjustment and temperature control in microsurgical reconstruction of the breast should be established to further improve free lfap outcome.

Objective To investigate the clinical effect of improved nursing intervention in blood glucose control of critical patients. Methods By means of historical control, 258 critical patients undergone intense insulin therapy were divided into the control group (n = 126) and the test group (n = 132). The control group was given conventional intensive insulin therapy. The test group was given improved guidelines on the use of insulin and improved nursing intervention. The following indexes of the two groups were documented and compared: the time required to achieve target blood glucose level [(11.95 ± 1.97) h vs (18.85 ± 3.59) h, t =19. 237 3 ,P <0. 01]; frequency of blood glucose measuring in four days, the range of everyday blood glucose and the occurrence of hypoglycemia during therapy. Results The test group had shorter time required to achieve target blood glucose level, lower frequency of blood glucose measuring, less fluctuation range of blood glucose and reduced occurrence of hypoglycemia during therapy than the control group (P < 0. 01). Conclusions The use of improved guidelines on the use of insulin and improved nursing intervention in intensive insulin therapy of critical patients can effectively control blood glucose, reduce frequency of hypoglycemia and improve prognosis.

OBJECTIVETo evaluate the available surgical treatment modalities so as to explore the optimal strategy of managing early breast cancer.
METHODSThe clinical data of 2173 consecutive early-stage breast cancer patients treated by surgery treatments were retrospectively reviewed in order to clarify the indications and contraindications of different modalities. Therapeutic outcome of different surgical treatment modes were compared in terms of recurrence-free survival ( RFS) , disease-free survival ( DFS) , overall survival (OS). The cosmetic results of breast conservation and reconstruction were also evaluated .
RESULTSThe median age of these patients was 51 years ranging from 18 to 91. Of 2173 patients, 547 had stage 0- I lesions and 1626 stage II , and 1155 (53. 2% ) premenopausal. The proportion of patients who received radical surgery, breast conservation and reconstruction after mastectomy was 83. 6% (1817/2173), 10. 5% (229/2173) and 2. 5% (55/2173) , respectively. Younger and premenopausal patients prefer conservative and reconstructive surgeries, which are reasonable for stage 0-I and non-invasive breast cancer patients. Conservative surgery was not suitable for Paget's disease of breast (P = 0. 004) , mastectomy followed by reconstruction in this type of cancer was up to 38. 5%. The recurrence and metastasis rate of conservation or mastectomy were similar with a comparable 3-year RFS of 97. 4% and 95. 4% , respectively; there were also no significant differences in RFS(P =0. 2435) , DFS( P =0. 1395) and OS(P =0. 9406) after having been followed for 3 to 64 months. Similarly, immediate reconstruction did not show any negative effects with only 1 recurrence and 1 metastasis. Aesthetic outcomes were assessed as excellent or good in 90. 0% of breast conservation surgery, and the acceptability of reconstruction was 94. 5%.
CONCLUSIONBreast conserving surgery not only has comparable survival as mastectomy, but also has better cosmetic outcomes. Immediate breast reconstruction can be a suitable option without compromising survival. It is very important in the management for early breast cancer by selecting the most suitable surgery mode for every individual patient not only to cure her disease but also to satisfy the patient psychologically. Conservation should be preferred prior to reconstruction whenever possible.
