Objective;To revise the third time the norm of Combined Raven's Test(CRT-C2) applied for 10 years by standardized sampling.Methods;According to the population distribution of national survey in 2001,sampling was chosen from 17 provinces of 6 administration districts.The range of each age group was one year(male;female 1;1).It was designed to have 240 children in each age group,from 7 to 16 years old in city and 7-14 years old in rural areas,with original CRT text book and instruction.Results;The averages of raw score among age groups had an obviously increase along with the age.The differences of same age group between city and countryside were showed significance.However,no difference of gender among all age groups was founded.The Cronbach's coefficient,reliability of re-test and split-half of rural children were 0.94,0.88 and 0.91 respectively.The correlation coefficients of test scores with the performances of Chinese and mathematics subject were 0.35 and 0.40.Conclusion;Two age norms of city(CRT-CC3)and countryside(CRT-RC3)were established based on new standardized sampling.

ObjectiveTo observe the effect of community-based rehabilitation (CBR) on older stroke patients in ability of activities of daily living (ADL).Methods50 older stroke patients were randomly divided into the rehabilitation group and control group. The rehabilitation group was treated with motor function exercise and ADL training, while the control group only took medicine. Two groups were evaluated with Barthel index before and after treatment. ResultsScores of Barthel index on the rehabilitation group were higher than that on the control group after treatment, and there was a significantly difference between two groups (P<0.01). Conclusions CBR has the significant effect on improving ADL in older stroke patients.

Pancreatic cancer is the third leading cause of cancer-related death in the world due to its high malignancy, difficult in early diagnosis, poor treatment efficacy, and high mortality. In recent years, benefiting from the progress of combined chemotherapy and neoadjuvant therapy, the prognosis of patients with pancreatic cancer has been improved to a certain extent. However, compared with other tumors, progress of precision medicine in pancreatic cancer is slow. The authors introduce the latest progress and difficulties in precision medicine of pancreatic cancer including molecular classification based on single gene and omics, monitoring tumor progression and guide treatment by minimally invasive liquid biopsy, as well as targeting therapy and immuno-therapy, in order to accelerate the development of precision medicine of pancreatic cancer.

ObjectiveTo investigate the possible mechanism of common bile duct ligation (CBDL) preconditioning alleviating subsequent renal ischemia/reperfusion injury.MethodsC57BL/6 mice was divided into 3 groups.In CBDL group,the common bile duct was transiently ligated at day 0 (d0),and recanalized after two days (d2) and two days later (d4). Unilateral renal ischemia/reperfusion injury was performed.Sham operation was done in Sham group at d0,then unilateral renal I/R was performed at d4. Control group was set as normal contrast. Total bilirubin (TB) was monitored.24 h after I/R (d5),we collected blood to detect creatinine (Cr),and the expression of heat-shock protein 27 (HSP-27) and endothelial nitric oxide synthase (eNOS) was monitored by Western blotting at d0,d2,d4,d5 four time points.ResultsAfter CBDL,TB fell to normal at d4.Cr levels in CBDL group were lower than in Sham group (P＜0.05),the protein expression levels of HSP-27 and eNOS were increased from d2 and sustained to d5 in CBDL group as compared with Sham group ( P ＜ 0.05 ).Conclusion CBDL preconditioning can obviously alleviate renal ischemia/reoerfusion injury in mice probably by up-regulating the expression of HSP-27 and eNOS.

Abstract?AlM:To investigate the effects of the MUC5AC levels and ocular function of the patients with glaucoma and cataract with combined surgery.? METHODS: Twenty - eight patients treated with glaucoma and cataract combined surgery were chosen as the observation group from December 2011 to June 2014 in our hospital, and other 28 cases of glaucoma and cataract did not undergo surgical treatment were selected as the control group, 30 healthy subjects were as healthy control group. the MUC5AC level and ocular surface score of the three subjects before surgery 1d, after 3 and 6mo were compared.?RESULTS: The NUC5AC of the two groups of patients was significantly lower than that of the healthy control group before surgery (P<0. 05), the ocular function score was significantly higher than the healthy control group ( P<0. 05). After 1mo, the MUC5AC of the observation group were significantly lower than that of before surgery ( P<0. 05), after 3mo MUC5AC content gradually increased to preoperative levels, after 6mo the MUC5AC were significantly higher than before surgery (P<0. 05). After 1mo, ocular function scores were significantly higher than the preoperative ( P< 0. 05 ), while after 3mo, ocular function scores decreased after 6mo of ocular surface function scores were significantly lower than the preoperative (P<0. 05). While the control group after 6mo, with the passage of time, the MUC5AC content gradually reduce, ocular function score increased gradually. ?CONCLUSlON:To treat the patients with glaucoma and cataract with combined surgery, the level of MUC5AC can temporary decrease. Ocular function score can temporary increase in, but after 3mo, it can be gradually improved.

Objective To observe the relationship of awake bispectral index (BISawake) and the postoperative cognitive dysfunction (POCD). Methods 100 patients aged 60~75 years with ASA status Ⅰ~Ⅱ, underwent elective lower abdominal surgery with intravenous anesthesia (propofol, remifentanyl and rocuronium). The BIS was adjusted in 40~60 during the surgery. Their cognitive function was assessed with the neuropsychological test battery commended by International study of postoperative cognitive dysfunction (ISPOCD). Results 8 patients withdrew for unwilling or serious complications. The BISawake was more than 65 in 68 patients (group A), and less than 65 in 24 patients (group B). The difference of the verbal learning immediate and delayed of Hopkins Verbal Learning Test-Revised was more in the group B than in the group A. Conclusion Lower BISawake may be associated with the decline of postoperative cognitive function.

Objective To explore a simple and effective way of establishing a mice orthotopic tracheal transplantation model in studying bronchiolitis obliterans to reduce operation time. Methods Tracheas from C57BL/6 mice (n=30) were im?planted into Balb/c mice (n=30). Grafts and hosts were matched according to body weight.Orotracheal intubation and endo-stentwas used for trachea anastomose and animal model was establish. Operating time was also noted. Grafts were harvest?ed on Days 15, 30 and 60 after transplantation, using HE staining to observe pathological changes of allograft. Trachea block?ing rate was also calculated. Results Until survival of trachea transplantation, the operative time of donor′s and the recipi?ent′tracheas resection were (7.0±1.0) min and (7.0±1.0) min respectively.Orotracheal intubation the endo-stentestablish?ment cost(1 ± 0.5)min. Trachea anastomose took(20.0 ± 4.0)min and the operation time last(43.0 ± 10.0)min. Conclusion The improvement of orthotopic tracheas transplantation usingOrotracheal intubation the endo-stenfor trachea anastomose is esay-operated and did required complicate skills and instruments with high successful rate. So it is an ideal and stable model in studying bronchiolitis obliterans.

Objective To compare the short-term clinical outcomes of hand-assisted laparoscopic surgery(HALS),laparoscopic-assisted surgery (LAS)and open surgery(OS)for colorectal cancer treatment. Methods The clinical data of 74 patients underwent HALS,LAS and OS for colorectal cancer treatment between October 2011 and December 2015 were assessed retrospectively. All the surgeries were performed by the same surgical team. The intraoperative details,postoperative recovery,postoperative complications,oncologic results and cost were compared among the three groups. Results A total of 24 patients in HALS group,25 patients in LAS group and 25 patients in OS group were finally included. The gen-eral data and oncologic baseline were comparable among the three groups. The comparative results showed that the operative time increase d and in-cision length shortened gradually in OS group,HALS group and LAS group(P<0.05). HALS group was favor of less number of trocars used com-pared with LAS group(P<0.05),but there was no statistical difference of the conversion rate between the two groups(P>0.05). In terms of post-operative recovery,postoperative complications and oncologic results,there was no statistical difference between the three groups(P>0.05). As for cost,the total cost and operative cost of OS group were lower than HALS group and LAS group(P<0.05),but there was no significant differ-ence between HALS group and LAS group(P>0.05). The material cost increase gradually in OS group ,HALS group and LAS group(P<0.05), and there was no significant difference on the part of other cost among the three groups(P>0.05). Conclusion HALS,LAS and OS are compen-satory with each other,and clinicians can choose the reasonable procedure according to personal proficiency and situation of patients.
