Objective To investigate the adjuvant effect of dimo-thylidioctyl ammonium bromide (DDA) and/or DDA-BCG polysaccharide nucleic acid( BCG-PSN), which was combined with a Mycobacterium tuberculosis fusion protein AMM ( Ag 8 5 B - MPT64190-198 - Mtb8.4 ) to boost BCG primed immunization. Methods DDA with or without BCG PSN was mixed with the fusion protein AMM to construct the boosting vaccine. Mice were immunized with BCG and then boosted twice with AMM formulated with the adjuvant DDA with or without BCG-PSN. PBS or BCG vaccination without boosting was used as control. The humoral and cell-mediated immune responses were analyzed by ELISA and ELISPOT. Moreover, the protective efficacy of BCG prime-AMM subunit vaccine boosting against Mycobacterium tuberculosis infection was analyzed. Results With in vitro stimulation of Ag85B and PPD( purified protein derivative) antigen, the number of IFN-γ secreting cells from the mice boosted twice by AMM/DDA/BCG-PSN and AMM/DDA were higher than BCG and PBS group (P <0.05). The CFU in lungs of mice boosted with AMM/DDA/BCG-PSN was less than that of PBS group(P <0.05), while the CFU of AMM/DDA-boosted mice was less than that of BCG and PBS group(P < 0.05).However, fewer lesions were seen in lungs of mice immunized with BCG alone or BCG-prime-AMM/DDA/BCG-PSN boosting than the other groups. Conclusion DDA is an idea adjuvant for tuberculosis subunit vaccine;BCG-PSN might play a role in alleviating the immunity-mediated pathology.

Objective To investigate the traditional Chinese medicine(TCM) syndromes distribution rule of nonalcoholic fatty liver disease(NAFLD) and its correlation with related clinical indexes.Methods The general condition,TCM four diagnostic methods,biochemical and CT results in 1950 cases of NAFLD in Chongqing City were investigated for analyzing the TCM syndromes distribution rule and its correlation with biochemistry and CT.Results In 1950 cases,the accumulation and binding of damp-heat,congestion of dampness turbidity,stagnation of liver-QI with spleen deficiency,intermin-gled phlegm and blood stasis and yin deficiency of both liver and kidney accounted for 36.62 ％,27.69 ％,19.38 ％,10.10 ％ and 6.21 ％ respectively;there was statistically significant difference in age among different TCM syndromes(P＜0.05);the vin deficiency syndrome of both liver and kidney and intermin-gled phlegm and blood stasis in severe fatty liver were maximal;glutamic-pyruvic transaminase(ALT) and glutamic-oxalacetic transaminase(AST) level was higher in the accumulation and binding of damp-heat;the level of fasting plasma gluco se(FBG) was higher in the yin deficiency syndrome of both liver and kidney;the total cholesterol(TC),triglyceride(TG) and FBG levels were lower in the stagnation of liver-QI with spleen deficiency,the differences were statistically significant(P＜0.05).Conclusion In NAFLD patients,the accumulation and binding of damp-heat distribution is maximal,the proportion of severe fatty liver with vin deficiency syndrome of both liver and kidney is higher.Different dialectical types may play an important role in the clinical indexes and disease development.

Objective: To provide data support for AIDS prevention and control by investigating HIV testing among technician school students in Guangzhou. Methods: A total of 1 112 students were investigated with a questionnaire about AIDS knowledge, attitude, sexual behavior and HIV testing through a stratified cluster random sampling method in October 2018. A Logistic regression analysis was conducted for influencing factors of students’ HIV testing. Results: The HIV testing rate of technician school student was 10.3%. The HIV testing rate (12.1%-24.3%) of male, under 18 years of age, with monthly living expenses over 3 000 yuan and with poor family atmosphere was higher than that of the corresponding group (6.6%-8.4%), the difference were statistically significant (χ2=12.07,7.25,10.73,9.77, P<0.05). Multivariate Logistic regression analysis showed that <18 years of age, willingness to participate in relevant AIDS prevention activities, homosexuality, “support for multiple sexual partners” and having sexual behavior were associated with more HIV testing(P<0.05). Conclusion The incidence of sexual behavior of students in technician school is high while the rate of HIV testing is low, especially for male and male homosexuals.The health and education departments should strengthen students’ AIDS counseling and testing services and raise students’ awareness of AIDS risk in order to improve the coverage of students’ HIV testing.

Objective: To explore the management effects of health knowledge-attitude-practice education on phosphorous control in peritoneal dialysis patients with hyperphosphatemia. Methods: A total of 64 peritoneal dialysis patients with hyperphosphatemia with long-term stable follow-up in the People’s Hospital of Quzhou from 2016 to 2018 were selected, and randomly divided into control and intervention groups. The groups received regular health education and health knowledge-attitude-practice education for 3 months, respectively. T-test and paired t-test were used to analyze the difference in the two groups, before and after intervention, in the score of knowledge-attitude-practice, serum phosphorus level, daily dietary phosphorous, and dosage of phosphate binder. Results: Before the health education intervention,there was no significant difference between the two groups’ questionnaire score of knowledge-attitude-practice of hyperphosphatemia, serum phosphorus, intact parathyroid hormone (iPTH), daily dietary phosphorous, dosage of phosphorus binder, and weekly urea clearance index in gender, age, and other general information. After 3 months of health education, the total score, knowledge, and behavior scores were higher in both groups than before intervention, and the scores of the intervention group were significantly higher than the control group. The scores increased by 16.64, 6.15, and 9.52 points respectively in the control group, and by 26.26, 11.67, and 13.56 points respectively in the intervention group. There was no significant difference in attitudes and beliefs between the groups before and after the intervention. After the intervention, the serum phosphorus level decreased, dosage of phosphate binder increased in both groups, the daily dietary phosphorous and iPTH decreased in the intervention group. These differences were statistically significant. The serum phosphorus level of the intervention group (1.86±0.42) mmol/L was lower than the control group (1.97±0.33) mmol/L, and the daily dietary phosphorous of the intervention group (831.22±187.85) mg/d was lower than the control group (928.23±192.81) mg/d. The difference in dosage of phosphate binder and iPTH of the groups was not statistically significant. Conclusions Health knowledge-attitude-practice education in peritoneal dialysis patients with hyperphosphatemia can improve their level of knowledge-attitude-practice, and promote the reduction of serum phosphorus.

Objective To summarize and analyze the pathological data of 431 cases of renal biopsy from Quzhou, Zhe-jiang and to discuss the epidemiological characters via pathological distribution in Quzhou. Methods A total of 431 patients with kidney diseases hospitalized between January 2012 and December 2014 by our hospital were reviewed and their epidemiological characters and distribution of pathological patterns were analyzed. Results Among the 431 speci-mens, 181 cases were from males (42.0%), and 250 were females (58.0%, male/female=1:1.38). As to the clinical types of disease, the most common disease was nephrotic syndrome (NS, 178 cases, 41.3%), followed by chronic glomeru-lonephritis (CGN, 142 cases, 32.9%). As to the etiologic classification, a majority of 342 cases were primary glomeru-lonephritis (PGN, 79.3%), 77 cases were secondary glomerulonephritis (SGN, 17.9%), 11 cases were tubulo-interstitial disease(TID, 2.6%), and 1 case was renal transplantation disease(0.2%). Among the PGN patients, IgA nephropathy (IgAN) and membranous nephropathy(MN) were most commonly observed, accounting for 32.7%and 24.5%, respectively. Of the SGN patients, lupus nephritis(LN) was most common, accounting for 40.2%, which was followed by Henoch-Schonlein purpura nephritis (HSPGN, 18.2%) and hepatitis b virus-associated glomerulonephritis (HBVGN, 13.0%). Conclusion PGN is the most common etiological factor of kidney biopsy, with IgAN and MN at most. LN is the main type of SGN, followed by HSPGN and HBVGN. In Quzhou, Zhejiang, the incidence rate is higher in young adults, indi-cating that special attention should be paid on IgAN, MN and LN in prevention and treatment of kidney diseases.

Objective To compare the clinical effects of minimally invasive percutaneous plate osteosyn-thesis(MIPPO)and interlocking intramedullary nail(IMN)internal fixation in the treatment of segmental tibial shaft fractures.Methods A total of 41 patients with segmental tibial shaft fractures in the Affiliated People's Hospital of Jiangsu University and Northern Jiangsu People's Hospital were selected as the study subjects,including 22 cases in the MIPPO group and 19 cases in the IMN group.All patients were followed up for 1 year.The clinical data such as the intraoperative bleeding volume,total blood loss volume(the difference value of hemoglobin before operation and on postoperative 1 d),postoperative early loading time,fracture healing time,incidence rate of postoperative complications and Johner Wruhs functional score in postoperative 1 year were compared between the two groups.Results Compared with the MIPPO group,the fracture heal-ing time in the IMN group was shorter[(17.39±2.10)weeks vs.(19.34±3.22)weeks,P＜0.05)],postoper-ative loading time was early[(6.93±1.04)weeks vs.(8.71±1.38)weeks,P＜0.05],total blood loss volume was greater[(32.89±6.55)g/L vs.(18.36±4.27)g/L,P=0.177)],but the intraoperative average blood loss had no statistical difference between the two groups[(99.33±31.62)mL vs.(87.34±24.15)mL,P=0.177].There was 1 case of malunion with a forward angle of 8° in the IMN group,1 case of infection,and the incidence rate of complications was 10.53％.In the MIPPO group,there were 3 cases of bone nonunion,2 ca-ses of infection and the incidence rate of complications was 22.73％.The complication incidence rate and the excellent and good rate of Johner Wruhs functional score in postoperative 1 year had no statistical difference between the two groups.Conclusion IMN could provide the stronger fixation,shorter fracture healing time,and early weight bearing functional exercise,which is the better choice for treatment of segmental tibial frac-tures.

OBJECTIVE: To evaluate the value of super-elective transcatheter external carotid arterial embolization (TAE) in the treatment of intractable epistaxis. METHOD: Forty-six cases of intractable epistaxis were selected, TAE was performed in 36 cases and externa carotid artery ligation was elected in 10 cases. RESULT: The curing rate was 88.9% (32/36) in cases treated by TAE and was 40.0% (4/10) in cased treated by external carotid artery ligation, and the average hospital days of the former was 4.8 days, while the latter was 10 days. Recurrency were effectively stopped bleeding by all kinds of methods, and complications were rare. CONCLUSION Transcatheter external carotid arterial embolization is a simple, safe and effective treatment for the intractable epistaxis, which has more advantages than external carotid artery ligation, and comprehensive methods can effectively and thoroughly cure intractable epistaxis.

Purpose: This study was performed to investigate the association of Glasgow prognostic score (GPS), combined positive score (CPS), and clinicopathological characteristics of locally advanced rectal cancer. Methods: Between February 2012 and February 2018, 103 patients with locally advanced rectal cancer treated by neoadjuvant chemoradiotherapy and total mesorectal excision (TME) were retrospectively evaluated. Results: According to the classification of the GPS, 85 (82.5%), 13 (12.6%), and 5 patients (4.9%) were classified as a score of 0, 1, and 2, respectively. Patients were classified into the GPS-low group (GPS of 0, n = 85) and GPS-high group (GPS of 1 or 2, n = 18) with an area under the curve of 0.582 for overall survival (OS). The mean programmed death-ligand 1 (PD-L1) CPS of the whole group was 2.24 (range, 0–70). The PD-L1 CPS of the GPS-high group was higher than the GPS-low group (P < 0.001). Multivariate analysis by Cox proportional hazards model indicated that GPS was associated with OS and diseasefree survival (DFS). Furthermore, PD-L1 CPS was associated with DFS (hazard ratio, 1.050; 95% confidence interval, 1.017– 1.083; P = 0.003). Conclusion Elevated GPS was related to the PD-L1 CPS. GPS and PD-L1 CPS were associated with the prognosis of locally advanced rectal cancer treated with neoadjuvant chemoradiotherapy followed by TME.
