Objective To investigate the clinical efficacy for different treatments of stage Ⅳ right colorectal cancer and its prognostic factors.Methods The clinical data of 106 patients with stage Ⅳ right colorectal cancer who were admitted to the First People's Hospital of Chenzhou from January 2008 to December 2013 were retrospectively analyzed.Among the 106 patients,42 patients receiving palliative resection were allocated to the palliative resection group,30 patients receiving colostomy were allocated to the colostomy group,20 patients receiving bypass surgery were allocated to the bypass group and 14 patients without treatment were allocated to the non-treatment group.Fluorouracil + leucovorin (5-FU/LV) were used as postoperative chemotherapeutics,and the time of chemotherapy was 2 to 6 months.The follow-up was applied to the patients by outpatient examination and telephone interview till February 2014.The non-normal distribution data were described as median and range.The survival curve was drawn by Kaplan-Meier method,and the survival rate was analyzed using the Log-rank test.The continuous variables were cut into the categorical variables.The univariate analysis of categorical variables was done using chi-square test,and the multivariate analysis was done using the COX regression model.Results The incidences of postoperative complications in the palliative resection group,in the colostomy group and in the bypass group were 47.6％ (20/42),40.0％ (12/30) and 65.0％ (13/20),respectively,with no significant difference (x2=3.053,P ＞ 0.05).One-hundred patients were followed up for 14.0 months (range,3.0-40.0 months),with overall median survival time of 10.3 months (range,2.6-27.0 months) and the 1-,2-year survival rates of 36.8％ and 6.7％.The median survival time and 1-,2-year survival rates were 11.5 months (range,4.3-27.0 months),47.6％,16.7％ in the palliative resection group,8.5 months (range,3.5-18.0 months),20.0％,0 in the colostomy group,9.0 months (range,3.0-13.0 months),15.0％,0 in the bypass surgery and 5.0 months (range,2.6-10.0 months),0,0 in the non-treatment group,showing a significant difference in the prognosis of patients among the 4 groups (x2 =42.395,P ＜ 0.05).The prognosis of patients in the palliative resection group were significantly different from those in the other 3 groups (x2 =5.786,6.178,10.378,P ＜0.05),there was no significant difference in the prognosis of patients between the colostomy group and the bypass surgery group (x2 =0.203,P ＞ 0.05).The results of univariate analysis showed that T stage,N stage,tumor differentiation,preoperative obstruction,peritoneal implantation,methods of treatment,chemotherapy and postoperative complications were related factors affecting the prognosis of patients with stage Ⅳ right colorectal cancer (x2=37.428,48.586,32.550,22.739,33.562,42.395,21.517,11.530,P＜0.05).T4 stage,N2 stage,poor-differentiated tumors and peritoneal implantation were independent risk factors affecting the poor prognosis of patients with stage Ⅳ right colorectal cancer (RR =2.336,2.945,2.182,3.500,95％ confidence interval:1.102-4.953,1.156-7.501,1.003-4.749,1.573-7.787,P ＜0.05).The postoperative chemotherapy was an independent factor affecting the good prognosis of patients with stage Ⅳ right colorectal cancer (RR =0.495,95％ confidence interval:0.271-0.904,P ＜ 0.05).Conclusion Palliative resection can improve the prognosis of patients with stage Ⅳ right colorectal cancer.T4 stage,N2 stage,poor-differentiated tumor,and peritoneal implantation were independent risk factors affecting the poor prognosis of patients with stage Ⅳ right colorectal cancer,while postoperative chemotherapy was an independent factor affecting the good prognosis of patients with stage Ⅳ right colorectal cancer.

Objective: To compare the predictive value of the two concepts for complications by comparing the incidences of surgical complications associated with different tip-apex distance (TAD) and calcar referenced tip-apex distance (Cal-TAD) in the treatment of femoral intertrochanteric fractures with Asian type proximal femoral nail (APFN) fixation. Methods: A total of 188 cases of femoral intertrochanteric fractures treated with APFN fixation between January 2014 and December 2018 were collected according to inclusion criteria. TAD and Cal-TAD were measured on the X-ray film at immediate after operation; the patients were divided into two groups according to the measurement results: <25 mm and ≥25 mm. Gender, age, and fracture side and AO type were recorded. The patients in each group were reviewed whether there was delayed fracture union or nonunion, whether the screw blade moved axially, whether the femoral neck collapsed or even screw blade cut out, whether the internal fixator became loose or broken within 12 months after operation. Then statistical analysis was performed. Results: There were 119 patients with TAD<25 mm and 69 patients with TAD≥25 mm, and 142 patients with Cal-TAD<25 mm and 46 patients with Cal-TAD≥25 mm. There was no significant difference in gender, age, or fracture side and AO type between groups ( P>0.05). During the follow-up, 6 patients (5.04%) with TAD<25 mm, 10 patients (14.49%) with TAD≥25 mm had complications, and 1 patient (0.70%) with Cal-TAD<25 mm and 15 patients (32.61%) with Cal-TAD≥25 mm had complications. There were significant differences in the incidence of complication between the patients with different TAD, between the patients with different Cal-TAD, and between patients with TAD<25 mm and Cal-TAD<25 mm ( P<0.05). Conclusion: In the operation of femoral intertrochanteric fracture with APFN fixation, surgical complications can be significantly reduced when TAD or Cal-TAD was controlled within 25 mm, Cal-TAD is more significant in the prediction of postoperative complications.

Objective: To compare the postoperative tibial malrotation between traditional minimally invasive plate osteosynthesis (MIPO) and three-dimensional printing-assisted MIPO (3D-MIPO) for different types of tibial fractures, and explore the change of these differences. Methods: A prospective randomized controlled trial was conducted. The 120 patients with unilateral tibial fracture who met the selection criteria between January 2016 and October 2018 (40 patients in each of AO types A, B, and C) into the trial group (20 patients, 3D-MIPO) and the control group (20 patients, traditional MIPO) at ratio of 1∶1. There was no significant difference between the two groups (P>0.05) in gender, age, fracture site, and other general information. The bilateral tibial rotation angles were measured on the CT images within 1 week after operation, and the difference of tibial rotation angle between affected and unaffected sides was calculated. The tibial malrotation was defined when the difference exceeded 10°. The degree of tibial rotation and the incidence of malrotation between the two groups in different types of tibial fractures were compared. Results: Postoperative infection occurred in 1 case, and improved after the dressing change and anti-inflammatory treatment. No complications such as loosening and displacement of internal fixation occurred. There was no significant difference in the difference of bilateral tibial rotation angles between the two groups in type A fractures after operation (t=0.559, P=0.580); while in types B and C fractures, the differences of bilateral tibial rotation angles in control group were significantly higher than those in trial group (P<0.05). There was no significant difference in distribution of internal or external rotation between the two groups in types A, B, and C fractures (P>0.05). No malrotation occurred in type A fractures, and there was no significant difference in the incidence of malrotation between the two groups in type B fractures (P=1.000). The incidence of malrotation in control group was significantly higher than that in trial group in type C fractures (P=0.044). Conclusion: 3D-MIPO has the same anti-malrotation effect as traditional MIPO for type A tibial fracture, but for types B and C tibial fractures, the anti-malrotation effect of 3D-MIPO is significantly better than that of traditional MIPO. The more complex the fracture type is, the more significant this advantage is.

Objective: To study the mechanism of baicalin in inhibiting Mycobacterium tuberculosis（MTB）and to provide reference for drug-resistant tuberculosis treatment. Methods: Forty male Kunming mice were injected isoniazid-resistant MTB into their tail veins to build models of infection. They were evenly divided into MTB group,isophosiazone group,NF-κB inhibition group and baicalicin group according to treatment. The lung tissue and peripheral blood of the mice were collected on the 8th day after modeling. The morphological changes of the lungs were observed by HE staining. The number of MTB in lung tissue was detected by acid-fast staining and quantitative PCR. The number of macrophagein lung tissue was detected by immunohistochemistry. The expression of NF-κB and TLR4 in monocytes/macrophages were detected by flow cytometry. Results: The average weight of mice in the baicalicin group was significantly higher than that in the MTB group,the isophosiazone group and the NF-κBinhibition group（P<0.05）. The average fluorescence intensity of NF-κB and TLR4 in monocytes/macrophages in the baicalicin group were 448.21±30.61 and 401.01±34.58,which were significantly higher than those in the MTB group and the isophosiazone group（P<0.05）. Typical tuberculous chronic granulomatous lesions were observed in the MTB group,isophosiazone group and NF-κB inhibition group,except the baicalin group. The mean number of MTB and CD68+ macrophagesin lung tissue of mice in the baicalin group were significantly less than that in the MTB group,the isophosiazone group and the NF-κB inhibition group（P<0.05）. Conclusion Baicalin achieves an anti-tuberculosis effect by regulating the expression of NF-κB and TLR4 in macrophages,which can be weakened by adding NF-κB inhibitor.

Objective To study the effect of using different tibial nerve proximal muscle branchs to repair deep peroneal nerve injury in animal experiment, and to screen out the most optimal donor nerve branch. Methods From June, 2016 to August, 2016, 64 adult female SD rats were randomly divided into 4 groups, which were LHG (using lateral head of gastrocnemius to repair peroneal nerve), MHG(using medial head of gastrocnemius to repair peroneal nerve), SNB (using soleus nerve branch to repair peroneal nerve), and blank. There were16 rats in each group. At 4 and 8 weeks after surgery, each group were tested on behavior, electrophysiology, muscle tension, muscle wet weight and histology, to evaluate function recovery of the muscles controlled by deep peroneal nerve in each group, and to compare recovery of the deep peroneal nerve repaired by different tibial nerve branches. Results Eight weeks after surgery,right foot of the rats in LHG,MHG and SNB group can be extended,toes can be completely opened. Rats in blank group showed limping gait, whose right foot can not be extended, right toe can not be opened, and muscle atrophied. At 4 and 8 weeks after the operation, the recovery rate of LHG, MHG, SNB group (at 4th weeks, 33.60 ±2.22)%, 33.07 ±2.38% and 35.91 ±2.02%; at 8th weeks, 67.16 ±5.74)%, 66.56 ±3.18% and 73.17 ± 5.33%, respectively)was higher than blank group(7.71±1.05% and 7.84±0.78%, respectively)on CMAP amplitude, tibialis anterior muscle contractility, tibialis anterior muscle cell area, muscle cell area. SNB group was superior to the LHG group and LHG group.And the difference was statistically significant(P<0.05). Conclusion All the proxi-mal tibial nerve muscle branchs can be used to repair the deep peroneal nerve injury, and the soleus nerve branch is the preferred donor nerve.

OBJECTIVEA Dengue outbreak was reported in Dongfen town Jianou county, Fujian province on September 19, 2014. The goal of this project was to explore the role of syndromic surveillance program in the practice of early detection on disease outbreak through the case mentioned above.

METHODSThe authors retrospectively collected data related to Outpatient log and Pharmacy drug use in Dongfen township hospital through the electronic information system of the hospital from August to November, 2014. All the abnormal events were recorded, according to related data on fever and drug use. Description of fever, syndromic characteristics, correlation and Linear regression analyses were conducted, using the surveillance data on fever syndrome and drug use from the pharmacy.

RESULTSA total of 1 102 cases with fever and 2 437 fever-related clinic visits were reported which showing an increased number of 19.6, 10.2 times respectively, when compared to the same period of the previous year in which men accounted for 45.3% (499/1 102) and female accounted for 54.7% (603/1 102). Age groups presented an atypical type " M" type. 5 and 10 year olds groups formed the largest proportion, accounted for 11.5% (127/1 102) of the total number os the patients. The correlation coefficient ranged from 0.85 to 0.97 (P<0.05). Data from the syndromic surveillance program showed an " outbreak" was occured in August 23, 2014.

CONCLUSIONSCompared to routine surveillance program, the syndromic surveillance program could detect the appearence of an outbreak, a month or even more earlier. The role of syndromic surveillance program needs to be further explored.
