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 explore the effects of extracts from Siegesbeckiae herba (HS) on doxorubicin (DOX)-induced chronic myocardial injury in mice. METHODS:48 mice were randomly divided into 3 groups. Mice in blank control(Con)group received distilled water once every day,ig,and normal saline(2 mL/100 g)once every day,ip,for 8 weeks;mice in DOX mice received distilled water(2 mL/100 g)once every day,ig,and DOX(3 mg/kg)once every week,ip,for 8 weeks;mice in DOX+HS group received HS(340 mg/kg)once every day,ig,and DOX(3 mg/kg)once every week,ip,for 8 weeks. After administra-tion,body mass,heart coefficient,cardiac function changes,serum biochemical index levels [alanine aminotransferase(ALT),as-partate aminotransferase (AST), creatine phosphokinase (CK), creatine kinase isoenzyme (CK-MB), lactate dehydrogenase (LDH)and total cholesterol(TC)] of mice were determined. RESULTS:Compared with Con group,body mass of mice in DOX group was decreased(P<0.01);heart coefficient was increased(P<0.05);heart rate slowed down,R-wave was increased(P<0.05 or P<0.01);serum biochemical indexed were increased,there was significant difference in AST(P<0.01). Compared with DOX group,heart coefficient of mice in DOX+HS group was decreased (P<0.01);heart rate was increased (P<0.01);serum biochemical indexes were decreased,there was significant differences in CK,LDH,TC(P<0.01). CONCLUSIONS:HS has cer-tain protective effects on DOX-induced chronic myocardial injury in mice.

Objective To study the effects of rehabilitation training on learning and memory ability and the expression of growth-associated protein-43(GAP-43)in rats with vascular dementia.Methods Forty-four female Sprague-Dawley rats were randomly assigned to a rehabilitation group(n=20),an immobilization group(n=20),and a sham-operation group(n=4).The rats in the former 2 groups were operated on to establish the experimental vascular dementia model by repeatedly ischemia/reperfusion injury of brain induced by ligation of bilateral common carotid arteries and lowering of blood pressure induced by intraabdominal injection of sodium nitroprusside.The rats in rehabilitation group were administered with rotating bar and rolling cage exercises for 1 hour once daily,while those in the immobilization group were immobilized and without any exercise:the rats in sham-operation group could move freely in cage.Learning and memory tests were preformed by using step-down avoidance test at the 27th and 28th days after operation.Immunohistochemical staining was used to detect GAP-43 expression in hippocampus CA1 area at different time points after operation. Results The rats in rehabilitation group demonstrated better learning and memory ability than those in immobilization group(P<0.01),and more GAP-43 expression in hippocampus CA1 ar-ea than those in immobilization group and sham-operation(P<0.01).Conclusion Rehabilitation training can im-prove the learning and memory ability of rats with experimental vascular dementia,and the mechanism is probably re-lated to the increase of GAP-43 in hippocampus CA1 area.

Objective To investigate the effect of rehabilitation training on learning and memory ability and the expression of neural cell adhesion molecule(NCAM)in rats modeling vascular dementia.Methods Foay-five female Sprague-Dawley rats were randomly assigned to a rehabilitation group(20 rats),an immobilization group(20 rats),or a sham-operation group(5 rats).The experimental vascular dementia model was established by repeatedly clipping the common carotid artery to induce repetitive isehemia-reperfusion,and by reducing blood pressure with intra-abdominal injection of sodium nitroprusside.The rats' learning and memory were tested on the 27th and 28th days after the operation using a water-maze step-down avoidance test.A RT-PCR technique was used to detect NCAM expression around the hippocampal area at different times after the operation.Results The rehabilitation group rats showed significantly better learning and memory ability than those in the immobilization group.NCAM was also more strongly expressed in their hippocampi than in those of the immobilization group and sham-operation group.Conclusion Rehabilitation can accelerate recovery of learning and memory ability in rats,and the mechanism possibly is related to the increase of NCAM expression in the hippocampus.

Objective: To study the effect of ultrasonic guidance in radial artery catheterization. Methods: From January 2017 to January 2018, 100 patients who received surgical treatment in Taizhou Central Hospital of Zhejiang Province and needed puncture and catheterization anesthesia during operation were randomly divided into control group (n=50) and observation group (n=50) according to digital table method.The control group adopted the traditional touch pulse method, while the observation group was guided by ultrasound.The first puncture success rate, the second puncture success rate, puncture time, puncture times, the vital sign index, incidence of adverse events, pain score, comfort score were compared between the two groups. Results: The first puncture success rate (80%) and the second puncture success rate (100%) of the observation group were higher than 62% and 88% of the control group (χ²=3.934, 6.383, all P<0.05). The single puncture time [(59.85±8.31)s] and total puncture time [(107.14±35.37)s] of the observation group were shorter than those of the control group (t=5.766, 6.398, all P<0.05), and the puncture times [(1.27±0.54) times] of the observation group was less than that of the control group (t=5.689, P<0.05). After puncture, the heart rate [(73.79±2.46)times/min] and average arterial pressure [(96.75±6.76)mmHg] of the observation group were all lower than those of the control group (t=5.058, 4.635, all P<0.05). The total incidence of adverse events such as subcutaneous hematoma and arterial wall penetration in the observation group (4%) was lower than that in the control group (18%) (χ²=5.005, P<0.05). The pain scores at puncture and after puncture of the observation group [(1.53±0.71)points, (1.28±0.60)points] were lower than those of the control group (t=5.545, 6.233, all P<0.05). The comfort scores at puncture and after puncture of the observation group [(91.25±9.64)points, (97.31±11.37)points] were higher than those of the control group (t=6.147, 6.226, all P<0.05). Conclusion Ultrasonic guidance can effectively improve the puncture efficiency, reduce the fluctuation of vital signs, pain, reduce the adverse events during puncture, and make the patients feel more comfortable.

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.
