Damage control surgery (DCS) has been widely used in the management of surgical patients. Crohn disease (CD) patients requiring surgery are usually severe and associated with high surgical risk, while the concept of DCS has not gained adequate attention in surgery for CD. Surgery is indicated in patients with CD to control symptoms, therefore major surgery should not be performed when the general health of the patients is not satisfactory. Use of DCS to guide surgery can reduce risk of treatment and improve clinical outcome The review is to discuss the necessity, objective, and methods of damage control surgery in the surgical treatment of Crohn disease.

OBJECTIVETo retrospectively investigate the difference in survival of pancreatic adenocarcinoma patients treated by radical surgery with or without adjuvant radiation therapy.
METHODSForty-four patients with pancreatic cancer underwent surgical resection with a curative intent, and were divided into two groups: surgery alone (n = 24) or surgery combined with postoperative external beam radiotherapy (EBRT) (n = 20). Survival as an endpoint was analyzed between the two groups.
RESULTSAll 44 patients completed their scheduled treatment. The median survival time of the patients treated with radical resection alone was 379 days versus 665 days for those treated with combined therapy. The 1-, 3-, 5-year survival rates of the patients treated with radical resection alone were 46.3%, 8.3%, 4.2% versus 65.2%, 20.2%, 14.1% for the patients treated with combined therapy, respectively, with a significant difference between the two groups (P = 0.017). The failures in local-regional relapse were significantly lower in the postoperative EBRT group than that in the surgery alone group (P < 0.05), while the additional postoperative radiation therapy did not increase the complication rate (P > 0.05).
CONCLUSIONPostoperative external beam radiation therapy can improve the survival in patients with pancreatic adenocarcinoma.

OBJECTIVETo study the culture of adventitious root of Salvia miltiorrhiza in vitro systemically.
METHODEffects of sucrose concentrations, medium pH, inoculum size and plant growth regulators on adventitious root growth and secondary metabolites production in S. miltiorrhiza were investigated.
RESULTWith the increase of initial sucrose concentration, adventitious root growth rates increased and tanshinone II A content decreased, while content of protocatechuic aldehyde showed a broken line change and its highest production was obtained under 30 g x L(-1) sucrose in the medium. As for the effect of medium pH, medium pH of 6.5, 5.5 (or 6.0) and 5.8 was favorable for adventitious root growth, tanshinone II A and protocatechuic aldehyde synthesis respectively. Furthermore, adventitious root growth, rate was greatly increased when inoculum size was 2.5%. MS medium added with 0.5 mg x L(-1) KT was much favorable for tanshinone II A and protocatechuic aldehyde accumulation.
CONCLUSIONParameters including sucrose concentrations, medium pH, inoculum size and plant growth regulators have distinct effects on the in vitro culture of adventitious root growth and secondary metabolites synthesis of S. miltiorrhiza.

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.

OBJECTIVETo study pharmacological effects of PEC (the oral liquid which consists of Panax quinquefolium, Epimedium brevicornum, Schisandra chinensis Bail and Cervus eplaphus) on mice.
METHODExperiments were carried out through swimming test, step-through, spontaneous activity and sleeping time.
RESULTWhen 5-10 mL x kg(-1) of PEC was given orally for 7 days, it could prolong swimming duration of mice in water tank, and increase the tolerant ability against oxygen-deficiency. PEC could also improve cognitive-deficiency induced by taking off sleep with force in mice after given orally for 7 days. The PEC could increase the spontaneous activity in mice, antagonize the inhabitation induced by Valium, and shorten the sleeping time caused by sodium pentobarbital.
CONCLUSIONPEC has strong potential neuro-pharmacological activities such as anti-fatigue, improving cognitive-deficiency in mice.

OBJECTIVESTo observe the effects of pioglitazone on morphological changes and connective tissue growth factor (CTGF) expression of the transforming growth factor beta (TGF b)-induced rat hepatic stellate cells (HSCs) in vitro, and to investigate the anti-fibrotic mechanism of pioglitazone.
METHODSCultured rat HSCs were divided into a no-treatment control group, a TGF b-treated group, and a TGFb plus different dosage pioglitazone-treated group. The morphological changes of the cultured HSCs were observed. The expression of CTGF was assessed by immunohistochemistry and flow cytometry. The level of collagen type III in the culture supernatant was measured by ELISA.
RESULTSTGFb induced morphological changes, and increased the expressions of CTGF and collagen type III of the HSCs (P less than 0.05). Pioglitazone prevented the TGFb induced morphological changes of the HSCs. The expression of CTGF and the levels of collagen type III in the pioglitazone group were lower than the TGF b-treated group (P less than 0.05). This prevention effect was dose-dependent (P less than 0.05).
CONCLUSIONPioglitazone blocks the excretion of CTGF and collagen type III of cultured HSCs, preventing the development of liver fibrosis.

BACKGROUNDProstatodynia remains a difficult clinical problem. Resiniferatoxin (RTX), an ultrapotent vanilloid, can produce a selective and long-lasting desensitization of nociception via C-fiber sensory neurons. Substance P (SP) and calcitonin gene-related peptide (CGRP) released from C-fibers are key neurotransmitters in visceral pain. In this study, we evaluated the analgesic effect of intrathecal RTX on rat prostatodynia.
METHODSMale Sprague-Dawley rats were divided into 3 groups for different treatment. In group A, sham operation was preformed. In group B, 100 microl complete Freund's adjuvant (CFA) was injected into the rat's bilateral ventral prostate to induce chronic inflammation. In group C, after prostatitis formed, 50 microl 10 nmol/L RTX was injected into the rat's lumbosacral (L5-S2) vertebral canal. SP and CGRP contents in the spinal cord were investigated by immunohistochemistry and radioimmunoassay (RIA). Their transcriptional levels in dorsal root ganglion (DRG) were determined by reverse transcriptase polymerase chain reaction (RT-PCR). In addition, pelvic nerve afferent discharge was recorded to explore the neuro-electrophysiological mechanisms underlying RTX-induced effect.
RESULTSSP and CGRP released in the spinal cord and their synthesis in DRG were increased significantly in response to CFA-induced chronic prostatitis, whereas this increase was effectively inhibited by intrathecal RTX. Meanwhile, pelvic nerve afferent electrical activity was enhanced significantly in rats with chronic prostatitis, but it was attenuated markedly in RTX-treated rats paralleled by the change of neuropeptides.
CONCLUSIONSIntrathecal RTX administration could produce an analgesic effect on rat prostatodynia. Suppression of pelvic nerve afferent electrical activity may be a crucial mechanism underlying RTX-induced analgesia. RTX intrathecal application may present a novel analgesic strategy of prostatodynia.
