OBJECTIVETo investigate the effectiveness of microbubble-enhanced ultrasound (MEUS) for detecting perforators preoperatively in supraclavicular flap surgery.
METHODSFrom May 2009 to October 2013, there were 20 patients (26 flaps were involved) who planned to undergo supraclavicular artery based flap surgeries to recover the large-area defects in head and neck. The MEUS together with regular color Doppler ultrasound ( CDUS) were conducted preoperatively to determine the anatomical features of perforators branching from supraclavicular arteries (SCA). The perforator with wider caliber, faster flow speed, longer pedicles and closer pivot point was selected and the flap was designed according to the observed results.
RESULTSThere were 37 perforators of SCA detected by CDUS, whose calibers were ranging from 0.5 to 0.8 mm [Mean: (0.6 ± 0.1) mm]. There were 48 perforators of SCA detected by MEUS. Compared to CDUS, the caliber obtained from MEUS for same vessel is significantly increased [(0.7 ± 0.3) mm vs (0.6 ± 0.1) mm, P < 0.05]. According to the results of MEUS and three-dimensional reconstructive techniques, in at least 65.4% (17/26) of the flaps, thoracic branch of SCA (TBSA) has large caliber and good flow velocity which can be regarded as the predominant vessel and used as the pedicle of flap. The results of the operations confirmed the existences of all the marked vessels. 25 flaps were obtained according to the preoperative plans and one case used perforators of internal mammary artery as free flaps since the perforator of SCA was found improper. The contrast-related complication occurred in one patient which was manifested by gastrointestinal adverse effect like nausea and anorexia. The patient recovered 1 day later without treatment. All the patients have been followed up for 3 to 16 months (Mean: 8 months) with well-survived flaps.
CONCLUSIONSThe perforators of SCA demonstrated significant variations and preoperative mapping was vital for the success of surgery. MEUS is a valuable imaging modality for the preoperative assessment of the vascular supply for supraclavicular artery based flap.

Depression is a serious mental illness with a high incidence. At present, we do not fully understand the specific pathological mechanisms of depression, and the efficacy of drug treatments is very limited. Recent studies have shown that epigenetic changes that occur in specific brain regions may be a key mechanism by which environmental factors to interact with individuals to influence the risk of depression. Therefore, drugs that target epigenetic regulation may become a new direction for the development of antidepressants. Histone deacetylase inhibitors (HDACi) are a class of compounds that inhibit histone deacetylase activity, which has been reported to be associated with depression; this article addresses the use of HDACi in preclinical studies, and their potential therapeutic role and limitations of use in depression.

Anaplastic lymphoma kinase (ALK)-positive diffuse large B-cell lymphoma (DLBCL) is a rare and distinct variant of DLBCL. It is classified as a unique subtype of DLBCL in the 2008 WHO classification of lymphomas. No standard and effective therapeutic regi-men is available for ALK+DLBCL because it shows a more aggressive clinical course and frequent relapse. Therefore, a standardized and individualized treatment is needed to benefit more patients diagnosed with ALK+DLBCL through a multiple disciplinary team. This arti-cle presents a case of an ALK+DLBCL patient who relapsed after transplantation and was successfully treated with the ALK kinase inhibi-tor Crizotinib.

Objective Few studies are reported on the factors influencing the selection of the surgical access for adenocarci-noma of the esophagogastric junction (AEG). This study aimed to investigate the factors influencing the selection of the surgical access for CT type-ⅡAEG. Methods We retrospectively analyzed 118 cases of CT type-ⅡAEG surgically treated in the Second Affiliated Hospital of Zhengzhou University and Henan Tumor Hospital from January 2015 to January 2017,92 via the abdominal access and the other 26 via the thoracoabdominal access. We performed univariate and multivariate logistic regression analyses on the factors that might influence the surgical approaches,such as gender,body mass index (BMI),degrees of the epigastric angle,pathological classifica-tion,and clinical stages. Results Logistic regression analysis showed that the degree of the epigastric angle was an independent fac-tor influencing the selection of the access of AEG (OR=0.250,95% CI: 0.098-0.639) (P<0.05). Conclusion In the surgical treatment of CT type-ⅡAEG,the abdominal access is preferable for patients with the epigastric angle> 90 degrees and the thoracoab-dominal access is recommended for those with the epigastric angle≤90 degrees.

OBJECTIVESTo investigate the difference of BPH incidence in two groups.
METHODS309 cadres and 314 farmers over 60 years old in district of Wannan have been investigated. The investigation included prostate volume (V), IPSS, L, Qmax, residual urine (R) and dietary constituents.
RESULTSThe intake of animal protein in cadres is more than that in farmers (u = 24.10, P < 0.01), and the incidence rate of BPH is significantly higher (91.1% vs 11.8%, chi 2 = 24.64, P < 0.001). Logistic regression shows that the intake of animal protein has a parallel relationship with BPH.
CONCLUSIONSIn the district of Wannan, the incidence of BPH in cadres is significantly higher than that of farmers, and it may be correlated with the amount of animal protein intake.

OBJECTIVETo discuss the integrated autologous fat graft technique in face recontouring.
METHODSIn this study we treated 83 cases of face recontouring with 3L3M technique (low pressure suction, low speed centrifugation, low volume, multi-plane, multi-tunnel, multi-point injection). Each case was treated 1-3 times and the interval period is 3-6 months. The result was based on comparing the photos taken from pre-operation and post operation, observing the expression recovery, cysts, local absorption, and patients self evaluation.
RESULTSLong time follow up showed that fat graft can be alive in the recipient site for long time after 1-3 times autologous fat injection. More than 73.5% patients were satisfactory with the curative effect while less than 4.8% patients were unsatisfactory.
CONCLUSION3L3M integrated fat graft technique is an effective and safe treatment in face recontouring.

OBJECTIVETo evaluate the efficacy and safety of fast track surgery(FTS) in patients undergoing laparoscopic colorectal resection.
METHODRandomized controlled trials(RCT) or clinical controlled trials(CCT) on fast-track surgery in patients undergoing laparoscopic colorectal resection were obtained from databases including CNKI, Wanfang, PubMed, EMBACE, and Cochrane Library between January 2000 and March 2012. Meta-analysis was performed with RevMan 5.1.
RESULTThere were 6 RCTs and 7 CCTs including 1795 patients. There were 955 patients in the FTS group and 840 in the control group. The time to passage of flatus was shorter(WMD=-1.37, 95%CI:-1.55~-1.19, P<0.05), time to resumption of diet/drink was shorter(WMD=-2.62, 95%CI:-2.69~-2.55, P<0.05), length of postoperative hospital stay was decreased(WMD=-1.63, 95%CI:-1.92~-1.34, P<0.05) and the incidence of postoperative complications were less(OR=0.52, 95%CI:0.41~0.67, P<0.05) in the FTS group. However, there were no differences in readmission(P>0.05).
CONCLUSIONFast-track surgery in patients undergoing laparoscopic colorectal resection can promote bowel function recovery, decrease the incidence of postoperative complications and length of hospital stay.
