Objective To explore the feasibility of laparoscopy-assisted total mesorectal excision(TME) for anterior resection of rectal cancer.Methods The clinical records of 42 patients with rectal cancer who underwentlaparoscopic TME from April 2006 to July 2008 were analyzed retrospectively.Results All the laparoscopic TME with anal sphincter preservation operations were successful;no case was converted to open procedure.The distal end of rectum was anastomosed by a reusable linear stapler.The average operative time was 195 min(170-230 min) and the operative blood loss 15 mL(10-30 mL).The time for bowel functionrecovery was 32 hours.One patient had postoperative dysuria,and one had intraoperative subcutaneousemphysema.No anastomotic leakage or infection of incisional wound occurred.Conclusions Laparoscopy-assisted anterior resection for rectal cancer is safe and feasible.

Objective To evaluate the effect of schistosomiasis control in Gongan County,Hubei Province by longitudinal ob-servations so as to provide the evidence for formulating the schistosomiasis control strategy in lake and marshland regions. Meth-ods The schistosomiasis epidemic data in Gongan County from 2000-2013 were collected by the retrospective research method, and analyzed about the changing tendency of human and cattle infection rates,and Oncomelania hupensis snail situation. Re-sults The tendency of schistosomiasis epidemic situation was descended from 2000 to 2013. The human infection rate declined from 12.62%in 2000 to 0.69%in 2013. The decline scope of human infection rate was 24.1%in the first stage,64.4%in the sec-ond stage,and 73.0%in the third stage. Eight acute schistosomiasis cases were reported in the first stage,15 cases in the second stage,and none in the third stage. The cattle infection rate declined from 6.50%in 2000 to 0.30%in 2013. The rise scope of cattle infection rate was 74.2%in the first stage,but the decline scope was 75.0%in the second stage and 87.6%in the third stage. All the cattle were disposal at the end of 2013. The infection rate of snails,area with infected snails,and average density of living snails in the first stage increased by 18.1%,46.0%and 7.6%,respectively. The 3 indexes above-mentioned in the second stage de-creased by 76.8%,97.8%and 37.9%,respectively. In the third stage,the infection rate of snails and area with infected snails de-creased by both 100%,but the average density of living snails increased by 2.7%. The infected snails were found from 2000 to 2011,but none in 2012 and 2013. The infection rate of snails and area with infected snails dropped yearly,the infection rate of snails declined from 0.0007% in 2000 to 0.0002% in 2011,and the area with infected snails declined from 267.8 hm2 in 2000 to 6.37 hm2 in 2011. Conclusions After the implementation of the integrated schistosomiasis prevention and control strategy with the emphasis on infectious source control,the human and cattle schistosome infection rates decline significantly. Hereafter,it is necessary to prevent the schistosomiasis epidemic outbreak or rebound.

Objective To understand the schistosomiasis endemic situation at a national surveillance site in Gong an Coun-ty Hubei Province. Methods According to The Scheme of Schistosomiasis Surveillance in China the schistosome infection rates of residents and cattle and the Oncomelaniahupensissnail status were investigated yearly in Zhangjiahu Village a nation-al surveillance site in Gong an County from 2004 to 2013. Results From 2004 to 2013 the human schistosome infection rates decreased from 10.66%to 0.58% and the cattle schistosome infection rates from 12.75%to 0. Meanwhile the snail areas and densities reduced and the schistosome infected snails were eliminated. Conclusion The schistosomiasis endemic situa-tion declined dramatically at the surveillance site and schistosomiasis is well-controlled.

Objective: To study the cytocompatibility of nanophase alumina ceramics with osteoblasts. Methods: Alumina ceramics were prepared via wet chemistry techniques. The grain size of alumina of interest in the present study was determined by scanning electron microscopy and atomic force microscopy with image analysis software. Primary osteoblast culture was established from rat calvaria. Protein content, synthesis of alkaline phosphatase(ALP) and deposition of calcium-containing mineral by osteoblasts cultured on nanophase alumina ceramics and conventional alumina ceramics for 7, 14, 21 and 28 d were respectively examined. Results: The average surface grain size of the nanophase and conventional alumina compact formulations was 60 nm and 1.80 ?m respectively.Synthesis of ALP and deposition of calcium-containing mineral were significantly greater by osteoblasts cultured on nanophase than those on conventional ceramics after 21- and 28- day culture. Conclusions: Nanophase alumina may stimulate ALP synthesis and calcium deposition of osteoblasts.

Objective To compare the efficacy and side-effects of preoperative neoadjuvant uterine arterial chemoembolization and venous chemotherapy in treating cervical cancer in young female patients. Methods A total of 241 young females(≤35 years old) with cervical cancer were enrolled in this study. The clinical data were retrospectively analyzed. The patients were divided into group A (n=63) and group B (n=57). Patients in group A received preoperative neoadjuvant uterine arterial chemoembolization with subsequent surgery, while patients in group B were treated with preoperative neoadjuvant intravenous chemotherapy followed by surgery. The chemotherapy scheme included carboplatin (50 mg/m2) and gemcitabine (1 000 mg/m2). The short-term effect, the amount of blood loss during the surgery, pathological findings and the side-effects of the two groups were compared. The Kaplan-Meier method was used to calculate survival rate, and the log-rank test was used for survival difference analysis. Results The short-term response rate of group A was 90.5%, which was significantly higher than that of group B (71.9%), the difference between the two groups was statistically significant (χ2=7.5, P<0.05). The resection rate of group A was 95.2%, which was higher than that of group B (84.2%). The amount of intra-operative blood loss of group A and group B was (443±263) ml and (695±312) ml respectively, the difference was statistically significant (t=4.802, P<0.05). The pathological complete remission of group A and group B was 9.5%(6/63) and 5.3%(3/57)respectively; the differences in postoperative pathological results between the two groups were statistically significant (χ2=12.3, P<0.05). The side effect of group A was milder than that of group B (P<0.05). The 5-year progression-free survival (PFS) rate of group A and group B was 73.0% and 54.4% respectively (χ2=4.471, P<0.05);and the overall survival (OS) rate of group A and group B was 77.8%and 63.2%respectively (χ2=3.022, P>0.05). In both groups, the clinical stage, the pathological grade and the size (≥ 4 cm) of the tumor were the main factors that could influence the prognosis in young females with cervical cancer (P<0.05). Conclusion The short-term efficacy of preoperative uterine artery chemoembolization is better than that of preoperative intravenous chemotherapy for the treatment of cervical cancer in young female patients. Besides, this therapy carries mild side effect, and it can improve the 5-year progression-free survival rate, although the long-term survival rate has not been obviously improved.

Objective To investigate the clinical therapeutic effect of comprehensive treatment in young women with cervical car-cinoma.Methods A total of 52 young women with cervical carcinoma were treated with uterine artery chemoembolization.50 cases underwent radical hysterectomy and pelvic lymphadenectomy after interventional therapy.The patients with pathological risk factors were given supplementary radiotherapy.Results The clinical overall response rate was 88.5%.96.2% of patients underwent sur-gery and lymph node metastasis rate was 26.9%.The 2,5 year overall survival rates of patients were 91.5%,71.2% respectively. Conclusion The comprehensive treatment can improve overall survival rate and quality of life for young woman with cervical carci-noma.Postoperative patients with pathologically related risk factors should be treated with supplement chemoradiotherapy.
