Objective To evaluate the clinical value of color ultrasound guided coarse needle bioptic histo-pathology in the diagnosis of retroperitoneal solid mass. Methods 32 cases with retroperitoneal solid mass accepted coarse needle biopsy (CNB) guided by color ultrasound, and followed to surgical mass resection. The histopathologi-cal result of CNB was compared to the post-operative pathological diagnosis. Results CNB were successful in all ca-ses and no complications occurred. Compared with the pest-operative pathology,the accuracy of CNB was 93.75% (30/32). There was no false-negative and very low rate of false-positive (3.13% ,1/32) of CNB in diagnosing ma-lignant tumor. Conclusions CNB guided by color ultrasound is a safe and an effective method in diagnosis of retro-peritoneal solid mass.

Objective To research the impact of axillary limph node group dissection oriented by senti-nel lymph nodes instead of axillary dissection on upper limb lymph edema and disease -free survival ( DFS ).Methods We designed a randomized controlled research , which included 205 cases of operatable breast cancer (AJCC 7th:stage I or stage IIa)from Jan.2011 to Jan.2013.Those cases were separated into 2 groups randomly ( random number method ):group A underwent mastectomy ( or lumpectomy ) and axillary group lymphadenectomy oriented by sentinel lymph node biopsy ( SLNB) ( if positive continued for ALND ) while group B underwent mastec-tomy(or lumpectomy)and axillary lymph node dissection(ALND).All patients underwent SLNB by blue dye method and received adjuvant therapy after surgery according to National Comprehensive Cancer Network ( NCCN) guideline and Chinese anti-cancer association guideline .Results There were 101 cases in group A and 104 ca-ses in group B , but 1 case in group A was excluded for false negative of SLN.The midium follow-up was 30 months.There were no significant differences of average age , tumor size, grade, estrogen receptor (ER),proges-terone receptor ( PR) and human epidermal growth factor receptor 2 ( HER2 ) expression between the 2 groups. Group A had a lower frequency of lymph edema than group B (4.0%vs 17.3%,χ2 =9.384,P=0.002), and al-so a milder degree ( mild 2%vs 11.5%,middle 2%vs 3.8%,severe 0%vs 1.9%).There were no significant differences of upper limb sensory disorder (14.0%vs 16.3%,χ2 =0.218,P=0.641), neither of DFS(Log-Rank analysis:3-year average DFS 32.89 months vs 33.72 months,χ2 =0.186,P=0.667;Cox risk model analysis:HR=1.395,P=0.495)between the 2 groups.Conclusion Axillary group lymphadenectomy oriented by SLNB can reduce the happening of lymph edema from ALND and has a comparative effect on DFS as ALND .

Objective To measure the value of orthopedic physiological and operative severity score for the enumeration of mortality and morbidity (POSSUM) and Portsmouth modified POSSUM (P-POSSUM) scoring systems in predicting operative risks in aged hip fracture patients.Methods Orthopedic POSSUM and P-POSSUM were performed to predict complication incidence and mortality for 164 aged patients operated for hip fracture.Validation of the scoring systems was tested by assessing observed to expected ratio,discrimination,and calibration.Discriminative ability and calibration of both scores were estimated using receiver operation characteristic curve (ROC) and Hosmer-Lemeshow test respectively.Results Orthopedic POSSUM score performed in predicting incidence of postoperative complications showed overall observed to expected ratio of 0.86,area under the curve of 0.82,and good calibration (H2 =3.66,df=8,P ＞ 0.05).P-POSSUM performed in predicting mortality showed overall observed to expected ratio of 0.80,area under the curve of 0.93 and good calibration (H2 =3.21,df =4,P ＞ 0.05).While orthopedic POSSUM overestimated postoperative mortality (overall observed to expected ratio =0.27).Conclusion Orthopedic POSSUM and P-POSSUM scores are respectively accurate in predicting postoperative complication incidence and mortality in aged hip fracture patients,but orthopedic POSSUM score overestimates the mortality.

BACKGROUND: Oral inflammatory diseases usually cause alveolar bone loss and odontoseisis, and further impact dental occlusion. Extracorporeal shock wave therapy (ESWT) is a promising method for the repair of alveolar bone and improving osteogenic activity of alveolar osteoblasts, but its therapeutic efficacy and related mechanisms remain unclear. OBJECTIVE: To compare the effect of different intensities of ESWT on the proliferation and osteogenesis abilities of rat alveolar osteoblasts. METHODS: The rat alveolar osteoblasts were obtained and cultured in vitro, and further identified by alkaline phosphatase staining. 0.18, 0.36, and 0.50 mJ/mm2 ESWT was used to stimulate the rat alveolar osteoblasts, 100 pulses, respectively. RESULTS AND CONCLUSION: The levels of alkaline phosphatase and bone morphogenetic protein 2 were significantly increased in the 0.36 and 0.18 mJ/mm2 ESWT groups, especially in the 0.36 mJ/mm2 ESWT group (P < 0.05). 0.50 mJ/mm2 ESWT significantly decreased the proliferation ability of rat alveolar osteoblasts and downregulated the levels of alkaline phosphatase and bone morphogenetic protein 2 (P < 0.05). To conclude, ESWT (< 0.36 mJ/mm2) can improve the osteogenesis ability of rat alveolar osteoblasts with the intensity increasing, which provides a theoretical basis for the clinical use of ESWT in the alveolar bone repair.

With the emergence, development and innovation of minimally invasive surgical and laparoscopic technologies, minimally invasive technology has been gradually applied and promoted in different fields of surgery, and surgical indications have been constantly expanded. Robot-assisted surgical system has become a novel research hotspot due to its precision and minimal invasiveness. At present, robot-assisted surgical system can be applied in complex tumor surgery. How to apply robot-assisted surgery in the field of liver transplantation, especially in the living donor liver hepatectomy, has become a new research direction, which is also a challenge facing multiple scholars. In this article, the advantages of robot-assisted surgery, current status and major difficulties of robot living donor liver hepatectomy were reviewed, and the future of robot living donor liver hepatectomy was predicted, aiming to provide reference for promoting the application of robot-assisted surgery in clinical liver transplantation.

OBJECTIVETo investigate the correlation of the levels of interleukin-8 (IL-8) and IL-6 in the prostatic fluid with serum levels of serum prostate-specific antigen (PSA) in patients with benign prostatic hyperplasia (BPH) complicated by prostatitis.

METHODSA series of 211 patients undergoing surgery of BPH were divided into BPH group (n=75) and BPH with prostatitis group (n=136) according to the white blood cell count in the prostatic fluid. The clinical and laboratory findings were compared between the two groups, and stepwise regression analysis was used to assess the association of IL-8 and IL-6 with serum PSA level.

RESULTSNo significant differences were found in age, BMI, blood pressure, blood glucose, blood lipids, IPSS score, PSA-Ratio, or prostate volume between the two groups (P<0.05). The patients with prostatitis had significantly increased serum PSA and prostate fluid IL-8 and IL-6 levels compared with those without prostatitis (P<0.001). Multiple linear regression analysis showed that IL-8 and IL-6 levels and white blood cell count in the prostatic fluid were all positively correlated with serum PSA level.

CONCLUSIONProstatitis is an important risk factor for elevated serum PSA level in patients with BPH, and both IL-8 and IL-6 levels in the prostatic fluid are correlated with serum PSA level.
