Objective To evaluate the indication,operation pattern and therapeutic effect of ano-saving surgery for lower rectal carcinoma. Methods Retrospective analysis on the clinical feature of 320 patients with lower rectal carcinoma (postoperative time ≥5 years)treated by ano-saving surgery, the 5-year survival rate, local recurrence rate, and mortality were compared in the various operations. Results The success performed rate of ano-saving operation for lower rectal cancer was 58.5%(320/547).Among them, anastomotic leakage after surgery occurred in 4 cases (1.25%), and 26 cases had anastomostic narrowness (8.13%) within 1 year after surgery.The defecation function after surgery, in patients received colonic J pouch or transverse coloplasty pouch was much better than that in patients received coloanal or colorectal anastomosis. 5-year survival rates, and anastomostic recurrence rates were as follows:In ultra-low anastomosis were 63.24% and 10.27%. Park′s operation 66.67% and 5.13%, local resection 89.46% and 10.71%, respectively. 5-year recurrence rate in the pelvic soft tissue was 3.44%(11/320).Two cases died after operation. Conclusions Lower or ultra-low colon-rectum anastomosis becomes the main operative pattern in preserving anal sphincter in lower rectal cancer.Local resection of lower rectal tumor might be considered if the indecation is selected strictly. Colonic-J-pouch or transverse coloplasty pouch is good for improving the defecation function after ano-saving surgery for lower rectal cancer.

OBJECTIVEThis study aimed at using cone beam computed tomography (CBCT) to study the influence ofprolonged unilateral posterior teeth loss on bilateral condylar morphology.

METHODSThe CBCT images of 30 patients withprolonged unilateral posterior teeth loss and 30 healthy people as controls were corrected. Mimics 15.0 software was used tomeasure volume, area, distance, and bone density of condyle. The results were statistically analyzed.

RESULTSThe volumeand bone density of condylar head and the entire condyle on missing teeth side were less than the contralateral side (P<0.05).The area and bone density of condylar transverse plane were greater than the contralateral side (P<0.05).

CONCLUSIONAfter prolonged unilateral posterior teeth loss, adaptive reconstruction occurs in the bilateral condyles, and condyle of missing teethside is smaller than the contralateral side.

Objective To observe the ultrastructure and absorption function of colon mucosa in rat with ultra-short bowel syndrome. Methods Totally 30 SD rats were randomly divided into three groups: ultra-short bowel group (90%-95% of the intestine was surgically resected, n = 10), sham group (n = 10), and normal control group (n = 10). All animals were given with enteral nutrition. Scanning electron microscopy was performed 21 days later to observe the morphology of mucosal surface, and transmission electron microscopy was performed to observe the ultrastructural changes of intestinal epithelial cells. The absorption of colon to water, carbohydrates, and amino acid determined after 3 hours of closed perfusion of the colon with D-xylose solution and 15N-glycine on the continuous cycle of colon. Results As shown by the transmission electron microscopy, compared with the normal control group, rats in the ultra-short bowel group showed significantly decreased goblet cells on colonic mucosl surface, increased epithelial cells, longer and denser microvillus, increased area of membrane surface, increased number of cell-cell junctions, increased number of desmosome, tight junction, and gap junctions, higher development of endoplasmic reticulum and dictyosome, and increased number of mitochondria. As shown in the screening electron microscopy, compared with the normal rats, rats in the ultra-short bowl group had significantly deeper colon folds, thicker mucous membrane, increased number of bay openings, and longer and denser microvillus-like structures inside bays. The capability of water absorption was signicatnly higher in the ultra-short bowl group than in the sham group and normal control group (P = 0. 000) . The absorption rates of xylose and 15 N-glycine were also significantly higher in the ultra-short bowl group than in the control group (P ＜ 0. 01). Conclusions The absorption capability can be compensatively increased in rats with ultra-short bowel syndrome. Decreased apoptosis of colon mucosa cells, increased absorption cells, hyperplasia of microvilli, increased area of the membrane surface,and increased number of mitochondria may constitute its material and energy bases.

Objective To study the epidemiology and genotypes of extended-spectrum beta-lactamases (ESBL)-producing Escherichia coli (EC) and Klebsiella pneumoniae (KP) that caused community-onset bloodstream infections (COBSI) in 9 county hospitals of Zhejiang Province.Methods This is a multi-center, prospective, observational study.The cases and isolates with COBSI caused by EC and KP were consecutively collected from 9 county hospitals in Zhejiang Province between 1st March 2014 and 30th April 2015.The double disk diffusion method was used to confirm the production of ESBL.The ESBL genotypes were determined by polymerase chain reaction(PCR) amplification and sequence analysis.Multi-locus Sequence Typing (MLST) was used to analyze the homology of ESBL-producing isolates.Minimal inhibitory concentration (MIC) of frequently used drugs for ESBL-producing isolates was determined by in-vitro antimicrobial susceptibility tests.Results During the study period, a total of 172 cases with COBSI were collected and 171 cases were eligible, among which 126 were caused by EC and 45 were caused by KP.The overall prevalence of ESBL was 34.5% (59/171),and the prevalence of ESBL-EC and-KP was 41.3% (52/126) and 15.6% (7/45), respectively.CTX-M-type ESBL accounted for 96.6% (57/59) of all the ESBLs-producing isolates, and the most common type was CTX-M-14 (27.1%, 16/59), followed by CTX-M-55 (22%, 13/59).MLST analyses revealed significant genetic diversity among ESBL-EC and-KP.The most prevalent ST of ESBL-EC was ST131 (23.1%).In addition to carbapenems, cefoperazone/sulbactam, piperacillin/tazobactam, moxalactam, amikacin and fosfomycin also showed good in-vitro activity against ESBL-EC and-KP.Conclusions The prevalence of ESBL in EC and KP is high in 9 county hospitals of Zhejiang Province, and the most common genotypes are CTX-M-14 and CTX-M-55.The detection rate of ESBL in EC is higher than in KP.It could be considered adequate empirical therapy according to the results of antimicrobial susceptibility tests.Carbapenems, cefoperazone/sulbactam, piperacillin/tazobactam, moxalactam, amikacin and fosfomycin have good in-vitro activity against ESBL-EC and-KP.

Objective To investigate the level of care burden and self efficacy of caregivers of patients with spinal cord injury,and analyze their correlation.Methods By convenience sampling method,150 cases of spinal cord injury patients and their caregivers were investigated with Zarit Caregiver Burden Scale and general self-efficacy scale.Results The score of care burden of caregivers with spinal cord injury was (52.91 ± 11.56) points,self-efficacy score of caregivers was (19.63 ± 4.85) points.The score of care burden of caregivers and self-efficacy was highly negatively correlated.Conclusions We should pay more attention to improve the self-efficacy of caregivers of patients with spinal cord injury (SCI),in order to mitigate the care burden,improve care ability and health level of the patients' families.

Objective To investigate the real situation of the burden of the caregivers who take care of patients with spinal cord injury.Methods Using phenomenological research methods of qualitative study,information of 15 family caregivers of patients with spinal cord injury were collected through semi-structured interviews in Jiangxi province,and data were analyzed with Colaizzi 7-step analysis method.Results Four themes were summarized:weak social support system,heavy economic burden,insufficient care ability,mental and physical exhaustion; mental and physical exhaustion concluded three sub-themes:burnout,lifestyle changes,sad/helplessness.Conclusions Care burden of caregivers of patients with spinal cord injury includes four aspects:social,physical,psychological,and less caring capacity.Care workers should be concerned about the health status of the caregivers,give targeted care intervention,so that caregivers can be adapted to the caregivers' role,maintain and promote a high level of health of the patients and their families.

OBJECTIVEThe skeletal Class III malocclusion often occurs in ethnic Asia population, and it is difficult to obtain an ideal results if only treated with protraction headgear (PH).
