An online questionnaire to 103 professionals of traditional Chinese medicine (TCM) was conducted to acquire their recognition and understanding of international communicative competence. The results showed that foreign language communicative competence and solid medical knowledge are considered the most important qualities while the importance of global vision, strategic thinking, cross-cultural awareness/sensitivity and communicative strategy is comparatively underestimated. It was proposed that domestic TCM universities and colleges strive to improve the soft skills for TCM professionals and cultivate more interdisciplinary TCM talents armed with professional expertise, foreign language communicative competence as well as international and multicultural awareness.

Background:Gastric cancer is the result of comprehensive interactions among Helicobacter pylori(Hp)infection, environmental factors and host genetic factors. It has been demonstrated that rs2294008 polymorphism in prostate stem cell antigen(PSCA)gene is associated with increased risk of non-cardia gastric cancer. Aims:To investigate the relationship between PSCA rs2294008 polymorphism and precursors of gastric cancer. Methods:A total of 398 patients with gastric intestinal metaplasia( n = 328)and intraepithelial neoplasia( n = 70)from Nov. 2009 to Nov. 2015 at the Qingdao Municipal Hospital were enrolled,and 416 healthy subjects were served as controls. Genotype of PSCA rs2294008 was determined by direct DNA sequencing of PCR products,and Hp infection was examined by rapid urease test. Results:Significant difference in frequencies of CC,CT and TT genotypes of PSCA rs2294008 was observed between case and control groups(P = 0. 011);the frequency of TT genotype was significantly higher in case group than in control group (16. 3% vs. 9. 4% ,P = 0. 003). Compared with individuals carrying CC genotype,TT genotype carriers were found to be associated with a higher risk of precursors of gastric cancer(oR = 1. 840,95% CI:1. 174 ~ 2. 886). Taken individuals negative for Hp infection and carrying C allele(CC + CT)as reference,risk of precursors of gastric cancer was significantly increased by Hp infection(oR = 2. 389,95% CI:1. 799 ~ 3. 173)and Hp infection in combination with TT genotype (OR = 3. 335,95% CI:1. 935 ~ 5. 749),whereas TT genotype alone only slightly increased the risk(OR = 1. 783,95%CI:0. 900 ~ 3. 530). Conclusions:PSCA rs2294008 polymorphism is significantly associated with susceptibility to precursors of gastric cancer and Hp infection might further increase the risk in TT carriers.

Objective To observe the treatment of continuous passive motion(CPM) on talipes valgus in the chil-dren with cerebral palsy. Methods There were 57 children in this research including normal group and valgus group, the children in valgus group were randomly divided into control group, non-CPM group and CPM group. The control group didn’t receive any rehabilitation treatment. The non-CPM group received conventional rehabilita-tion treatment. The CPM group received conventional rehabilitation and CPM therapy. Evaluate the children in nor-mal group with plantar pressure analysis and evaluate each patient before treatment two and four months after treat-ment with plantar pressure analysis. Results Compared with the normal group, the percentage of medial midfoot (MMF) pressure, HEEL pressure, initial contact phase(ICP) and forefoot contact phase(FFCP) were obviously higher in valgus groups. On the other hand, the percentage of lateral forefoot ( LFF) pressure, lateral midfoot (LMF) pressure and foot flat phase(FFP) were obviously lower in valgus groups(P < 0. 05). The percentage of MMF pressure, and FFP became lower after treatment in both CPM group and non-CPM group while the percentage of ICP and FFCP became higher(P < 0. 05). In CPM group there was a more obvious change with the percentage of MMF pressure, ICP and FFCP compared with non-CPM group and the control group(P < 0. 05). Conclusion U-sing CPM can alleviate muscle spasms and contracture, correct the deformity of midfoot, enhance the muscle group coordination on foot and further more improve gait of patients with cerebral palsy.

controlling nutritional status (CONUT) after radical resection of colorectal cancer.Methods The clinical data of 180 patients who underwent radical resection of colorectal cancer at the Tumor Hospital of Xinjiang Medical University between June 2012 and June 2014 were retrospectively analyzed.Seventy patients with scores of NRS 2002 ≥ 3 were allocated into the A group including 40 with enteral nutritional support therapy in the A1 group and 30 without enteral nutritional support therapy in the A2 group, 60 patients with scores of NRS 2002 ＜ 3 and negative CONUT was allocated into the B group including 30 with enteral nutritional support therapy in the B1 group and 30 without enteral nutritional support therapy in the B2 group, 50 patients with scores of NRS 2002 ＜ 3 and positive CONUT was allocated into the C group including 25 with enteral nutritional support therapy in the Cl group and 25 without enteral nutritional support therapy in the C2 group.The nutritional status of patients was evaluated using a joint of NRS 2002 and CONUT.There was nutritional risk in patients with scores of NRS 2002≥3 or scores of NRS 2002 ＜ 3 and positive CONUT and no nutritional risk in patients with scores of NRS 2002 ＜ 3 and negative CONUT.Patients and their families would choose whether or not to undergo enteral nutritional support therapy after the risks being informed.Enteral nutritional support therapy included tube feeding enteral nutrition or oral nutriments with calories ≥41.84 k J/(kg · d) for more than 3 days.Observed indicators: (l)Nutritional indicators included fasting serum albumin (Alb), prealbumin and transferrin before operation, at postoperative day 1 and day 7.(2)Postoperative recovery included time to anal exsufflation, time of defecation, time for semifluid diet intake and duration of hospital stay.Measurement data with normal distribution were presented as x ± s, comparison among groups was analyzed using the t test and repeated measures

operation, (26 ± 4) g/L, (0.16 ± 0.05) g/L and (1.7 ± 0.4) g/L at postoperative day 1 and (25 ± 4) g/L,(0.16 ±0.04) g/L and (1.8 ±0.5)g/L at postoperative day 7, respectively.There were significant differences in the changing trends of the above 3 indicators between the 2 groups (F =5.625, 4.225, 8.221, P ＜0.05).Postoperative recovery: time to anal exsufflation, time of defecation, time for semifluid diet intake and duration of hospital stay were (1.9 ± 0.5) days, (2.3 ± 0.5) days, (8.6 ± 1.2) days, (14.7 ± 1.1) days in the A1 group and (3.0 ± 0.5) days, (4.5 ± 0.6) days, (11.4 ± 2.2) days, (17.8 ± 1.3) days in the A2 group, respectively,with significant differences between the 2 groups (t =-0.644,-12.200,-8.710,-11.650, P ＜ 0.05).Time to anal exsufflation, time of defecation, time for semifluid diet intake and duration of hospital stay were (1.2 ± 0.3)days, (3.2 ±0.7)days, (10.3 ± 1.4)days, (14.7 ±2.0)days in the B1 group and (1.5 ±0.5)days, (3.7 ± 0.6) days, (11.0 ± 1.2) days, (16.1 ± 1.5) days in the B2 group, respectively, with no significant difference between the 2 groups (t =-1.929,-1.033,-1.019,-1.171, P ＞0.05).Time to anal exsufflation, time of defecation, time for semifluid diet intake and duration of hospital stay were (1.8 ± 0.7) days, (2.1 ± 0.5) days,(7.6±1.2)days, (13.9 ±1.2)days in the C1 group and (3.1 ±0.5)days, (4.5 ±0.7)days, (11.4±2.4)days,(17.6 ± 1.3) days in the C2 group, respectively, with significant differences between the 2 groups (t =-5.934,-10.950,-10.010,-11.700, P ＜ 0.05).Conclusions A joint application of NRS2002 and CONUT after radical resection of colorectal cancer is exact and feasible for evaluating nutritional status of patients and guiding enteral nutritional support therapy.Patients should select nutritional support therapy after operation if there is nutritional risk.The proper nutritional support therapy can improve the postoperative nutritional status of patients with colorectal cancer, enhance the postoperative recovery and reduce the duration of hospital stay.

Objective The study aimed to evaluate the incidence rate and risk factors of early post-mastectomy pain syndrome (EPMPS) after surgery for breast cancer.Methods A retrospective study was carried out in 231 female patients with breast cancer who appeared EPMPS after surgery in the First Hospital of China Medical University from September 2012 to September 2014.They were followed-up for 3 months.Results Among 231 female patients with breast cancer,41.1％ (95/231) suffered from EPMPS.The incidence of EPMPS in women of 40-59 years old was 66.3％ (63/95),significantly higher than other age groups,RR=l.83,P＜0.05.Those who were submitted to axillary lymph node dissection and those without preservation of intercostobrachial nerve had shown a significantly increased risk of EPMPS compared with those with sentinel lymph node biopsy plus no surgery and preservation of intercostobrachial nerve patients (81 cases vs.14 cases,41 cases vs.18 cases,x2=19.921,P＜0.01;x2=11.045,P＜0.05).Conclusions The frequency of EPMPS in the middle-age women is high and possible explanations are unclear.Surgery of axilla affects the incidence of EPMPS,reassurance is key to coping with EPMPS in nursing and rehabilitation.
