Objective To express the capsid proteins of WU polyomavirus(WUPyV) for research and find antigen for diagnostic value. Methods Coding sequences of capsid proteins of WU polyomavirus by PCR were cloned in prokaryotic expression vector PGEX-20T. Recombinant plasmids were transformed into E. coli BL21(DE3) and induced by IPTG for proteins expression. Recombinant proteins were identified by Western blot. Results SDS-PAGE proved that recombinant proteins showed three bands with molecular relative mass of 69×103, 63×103 and 56×103. The recombinant proteins were recognized by anti-GST McAb. The antigenicity was tested by Western blot using 16 WU polyomavirus positive and 70 negative sera. Conclusion Recombinant VP1, VP2 and VP3 expressed in E. coli can combine with WUPyV-Ab and have good antigenicity. They can be used for further research.

Objective To summarize the magnetic resonance imaging/ 1 H-magnetic resonance spectroscopy (MRI/1 H-MRS) features of tumor-like inflammatory demyelinating diseases (TIDD),and investigate the clinical value of MRI/1 H-MRS.Methods MRI features of 10 cases of TIDD in brain confirmed by pathology were retrospectively analyzed and compared with pathology.Results The lesions mainly located in the white matter with mild mass effect.MRI scan all showed low T1 high T2 signal,and 7 cases showed high signal,3 cases showed slightly high or mixed signals on DWI.Enhanced MRI showed 5 cases with significant enhancement withopen loop sign,4 cases with significant patchy or nodular enhancement,1 case with mild flakes or linear enhancement.Three cases showed expanded blood vessels and plumbed to the lateral wall inside the edge of the lesions.1H-MRS performance showed 4 cases all with significantly increased Lac and Lip; 3 cases with rised glutamate and glutamine complex β,γ-Glx peaks,reduced N-acetylaspartate acid (NAA),increased Cho to varying degrees.All pathological changes were demyelination,perivascular inflammatory infiltration and reactive gliosis,hypertrophy and abnormal mitotic figure.Seven cases could be seen obesity glial cells.Conclusions TIDD had its salient MRI features:lesion had obvious edema and mild mass effect,MRI enhancement showed open loop sign and small veins expansed,on perfusion-weighted imaging it showed low perfusion.1H-MRS showed β,γ-Glx peaks,Lac and Lip peaks significantly increased,NAA slightly reduced,Cho mildly elevated.Comprehensively analyzing the MRI and 1H-MRS features,combined with clinical manifestations,contribute to the diagnosis of the disease.

OBJECTIVE:To provide reference for further implementation and perfection of National Essential Medicine Sys-tem. METHODS:Stratified random sampling method was used to select 252 doctors from Sichuan Luzhou. Questionnaire survey was performed among them about recognition and behavior of them to National Essential Medicine System. Related investigation da-ta was analyzed statistically. RESULTS:A total of 252 questionnaires were issued and 243 valid questionnaires were collected with effective recovery rate of 96.4%. Of 242 respondents who had heard of National Essential Medicine System,the respondents who had heard but not clear occupied the highest percentage (52.1%). Of 149 participants who had participated in national essential medicine knowledge training or study,the proportion ofonly one knowledge training or studywas the highest(57.0%). The sur-vey respondents had a maximum of 45.0% and a minimum of 16.5% of common sense about National Essential Medicine System. After the implementation of National Essential Medicine System,respondents often propagandized National Essential Medicine Sys-tem to diagnosis and treatment objects accounted for only 23.1%. The proportion ofno changechosen for items of work motiva-tion,work efficiency and workload was the highest (all occupied 58.3%);the proportion oflittle influencechosen for item of clinical medication habit was the highest(38.8%). 86.4% of respondents were willing to give priority to the use of national essen-tial medicines;the top 4 reasons wereto obtain training and guidance on the use of essential medicinesto set utilization rate of essential medicines in primary health care institutionsto strengthen the propaganda of National Essential Medicine Systemto evaluate physician's prescriptions regularly. 13.6% were not willing to give priority to the use of national essential medicines;the top 4 reasons werelack of the confidence of the use of national essential medicinespoor accessibility of essential medicinesfear of medical accidents due to prescription essential medicines,lead to medical disputesdon't know what is essential medi-cine. CONCLUSIONS:The primary physicians'perceptions of National Essential Medicine System and the implementation of the System in Luzhou need to be strengthened. The main reason is that few national essential medicine knowledge training or study and poor effects. That the government's supporting poli-cy is not perfect may be one of reasons.

Objective To observe the bone metabolism of psoriatic arthritis (PsA) and investigate the roles of some bone metabolism markers such as tartrate-resistant acid phosphatase 5b (TRACP5),C-terminal telopeptide of collagen-Ⅰ (CTX-Ⅰ) and BALP in PsA patients with bone destructions.Methods Sixty-five cases of psoriatic arthritis,30 cases of psoriasis and 30 cases of healthy people were enrolled.Bone mineral densities of lumbar spines and the left femoral necks were measured for all PsA patients using dual energy X-ray absorptiometry.The Serum levels of TRACP5b,CTX-Ⅰ,BALP of healthy controls,Ps and PsA patients were measured.The PsA group was further divided into bone destruction group and none bone destruction group by image datasets.The levels of TRACP5b,CTX-Ⅰ,BALP,PsAJAI,ESR and CRP from each group were detected.Mann-Whitney and x2 test were used for statistic analysis.Results TRACP5b levels of the healthy controls,Ps and PsA patients were (0.9±0.4),(0.7±0.5) and (2.0±1.4) U/L respectively,and were significantly higher in the PsA patients than those of the other two groups (Z=-3.698,-3.638; P＜0.05).The CTX-Ⅰ levels of these three groups were (0.9±0.8),(0.6±0.7) and (2.6±1.8) ng/ml respectively,and were also dramatically higher in the PsA patients than the other two groups (Z=-5.262,-5.734; P＜0.05).BALP levels of each group were (22±4),(22±4) and (25±7) U/L,and were also evidently higher in the PsA patients than patients in the other two groups (Z=-2.214,-2.000; P＜0.05).Meanwhile,the levels of TRACP5b [(2.6±1.4) U/L],CTX-Ⅰ [(3.1±1.8) ng/ml] and BALP [(26±7) U/L] were significantly higher in bone destruction group than those in the none bone destruction group [(1.2±1.0) U/L,(1.9±1.6) ng/ml,(23±6) U/L,Z=-3.544,-3.429,-2.083; P＜0.05].Conclusion The high levels of TRACP5b,CTX-Ⅰ and BALP in PsA indicate that there is bone metabolism imbalances in PsA.And the high levels of TRACP5b,CTX-Ⅰ and BALP in the bone destruction group suggest that the rises of TRACP5,CTX-Ⅰ and BALP levels may be related with bone erosions.

OBJECTIVETo evaluate the efficacy and safety of Fulu Baoxinping (FLBXP) oral liquid in the treatment of coronary heart disease patients with premature ventricular beat (PVB), differentiated as qi-yin deficiency with phlegm-stasis syndrome type.

METHODSAdopting randomized, double-blinded, double-simulated, positive drug parallel controlled and multi-centered clinical research method, 240 patients enrolled were randomly assigned equally to the treatment group treated with FLBXP 10 mL (containing 13.33 g of crude drug) thrice a day and the control group treated with Wenxin Granule 9 g thrice a day. Meanwhile, simulator of the test or positive control drug was given to them all correspondingly. The therapeutic course for them all was 28 days. Efficacy on PVB and TCM syndrome was observed.

RESULTSThe markedly effective rate and total effective rate on PVB were 55.0% and 78.4% in the treatment group, and 37.2% and 53.1% in the control group, significant difference between groups was shown in comparison of both indexes (P < 0.05). Dynamic ECG showed the total number of PVB decreased for 3460.59 +/- 6516.56 beats/24 h in the treatment group, and for 2148.36 +/- 5129.47 beats/24 h in the control group, difference between them showed no statistical significance (P > 0.05). The TCM syndrome score in both groups was markedly decreased after treatment when compared with before treatment (P < 0.01); the differences of the treated and the control groups were -9.34 +/- 4.21 and -8.08 +/- 4.33 respectively, showing sigificant difference (P < 0.05).

CONCLUSIONFLBXP oral liquid has certain effect on PVB in CHD patients of qi-yin deficiency with phlegm-stasis syndrome type, no obvious adverse reaction was found in the clinical trial.

Objective To construct recombinant adenovirus vector containing Rattus norvegicus microtubule-associated protein 4 gene,and transfect it into the rat cardiac myocytes cultured in vitro.Methods A pair of primers were designed,and full length MAP4 DNA was cloned from rat total mRNA by PCR.The PCR product was double-digested with restriction endonucleases NheⅠ and NocⅠ,and inserted orientationally into pShuttle2.The plasmid of pShuttle2-MAP4 was double-digested with restriction endonucleases NheⅠ and NocⅠ,and inserted BD Adeno-X~(TM) Virul DNA,named pAd2-MAP4.The non-recombinant adenovirus was screened out with PacⅠ, pAd2-MAP4 was linerized with SwaⅠ,and the recombinant virus genome was transfected into HEK293 cell line for packaging and amplification of Ad-MAP4 virus.The recombinant adenovirus was transfected into rat cardiac myocytes and MAP4 was identified by immunohistochemistry.Results The recombinant adenovirus-MAP4 was constructed successfully and the titer was about 2.3?10~(8) pfu/ml.The expression of MAP4 was enhanced at 48 h after the transfection.Conclusion We have successfully constructed a recombinant adenovirus Ad-MAP4 that has enforced the expression of MAP4 in vivo.

Objective:To observe the clinical effect of electroacupuncture(EA)combined with exercise therapy on balance function in patients with knee osteoarthritis(KOA). Methods:Seventy patients with KOA were randomly divided into a treatment group and a control group,with 35 cases in each group.The treatment group was treated with EA combined with exercise therapy.EA was applied to Dubi(ST35),Neixiyan(EX-LE4),Xuehai(SP10),Liangqiu(ST34),Yanglingquan(GB34),and Zusanli(ST 36).Exercise therapy(muscle strength training and knee mobility training)was applied after EA.The control group only received the same exercise therapy as the treatment group.The two groups were treated with the same course of treatment,3 times a week for 4 consecutive weeks,12 times in total,and followed up for 1 month.The Pro-Kin254P balance test system was used to measure the balance function parameters at 4 time points,including before treatment,after 1 session of treatment,after 12 sessions of treatment,and at 1-month follow-up after treatment.The visual analog scale(VAS)and the Western Ontario and McMaster Universities osteoarthritis index(WOMAC)scores were recorded. Results:The markedly effective rate and total effective rate in the treatment group were higher than those in the control group(P<0.01).The Romberg area,Romberg length,and VAS scores of the two groups decreased significantly after 1 session of treatment,12 sessions of treatment,and 1 month after treatment,and the differences between different time points in the same group were statistically significant(P<0.01).There were significant differences between the two groups at the same time point(P<0.05).The total WOMAC scores of the two groups after 1 session of treatment,12 sessions of treatment,and 1 month after treatment decreased significantly,and there were significant differences between different time points in the same group(P<0.05),but there was no significant difference between the two groups at the same time point(P>0.05). Conclusion:EA combined with exercise therapy or exercise therapy alone can enhance the balance function,relieve joint pain,and improve joint function in patients with KOA.EA combined with exercise therapy is superior to exercise therapy alone in improving balance function and pain,but the two treatment protocols have similar effects in improving joint function.

AIMBLT1 and BLT2 were both recently cloned and identified as two subtypes of leukotrine B4 (LTB4) receptors. With the usage of U-75302 and LY255283, the specific antagonists of BLT1 and BLT2 respectively, the involvement of BLT1 and BLT2 in the inflammatory and immunological responses was in vitro explored.

METHODS(1) To investigate inhibition of U-75302 and LY255283 on the proliferation of rat synovial cells, 3H-TdR incorporation into the cells was quantified. (2) Flow cytometric assay for interferon-gamma (IFN-gamma) and interleukine 4 (IL-4) profiles in CD4+ T lymphocytes from rat spleen was carried out to determine the ratio of Th1/Th2.

RESULTS(1) For inhibition on rat synovial cells proliferation, U-75302 exerted its effect only at a high concentration of 10 micromol/L and LY255283 at the concentrations of 10 micromol/L-10 micromol/L. (2) Both U-75302 and LY255283 could elevate the percentage of Th2, but could not influence that of Th1.

CONCLUSIONBLT1 and BLT2 were involved in the synovial cells proliferation change the ratio of Th1/Th2. Their meaning served as targets for prevention and treatment of infectious diseases should be emphasized.

OBJECTIVETo investigate the clinical symptoms and potential mutation in FGFR3 gene for a family featuring hereditary dwarfism in order to attain diagnosis and provide prenatal diagnosis.

METHODSFive patients and two unaffected relatives from the family, in addition with 100 healthy controls, were recruited. Genome DNA was extracted. Exons 10 and 13 of the FGFR3 gene were amplified using polymerase chain reaction (PCR). PCR products were sequenced in both directions.

RESULTSAll patients had similar features including short stature, short limbs, lumbar hyperlordosis but normal craniofacial features. A heterozygous mutation G1620T (N540K) was identified in the cDNA from all patients but not in the unaffected relatives and 100 control subjects. A heterozygous G380R mutation was excluded.

CONCLUSIONThe hereditary dwarfism featured by this family has been caused by hypochondroplasia (HCH) due to a N540K mutation in the FGFR3 gene.

OBJECTIVESTo probe into the relationship between the CT grouping of liver cirrhosis and its complications as well as clinical condition.

METHODSOn the basis of CT findings in 357 cases with liver cirrhosis, CT grouping of the cirrhosis was performed. The complications of the cirrhosis, including enlargement of spleen, varicose collateral veins, ascites, pleurorrhea, primary liver carcinoma, gallbladder stone, etc, of all groups were analyzed. According to examination the blood routine, and the serum urea nitrogen (SUN), creatinine and uric acid, the condition of spleen function accentuation and liver-kidney syndrome were estimated.

RESULTSThree hundred and fifty-seven cases with cirrhosis were divided into homogeneous group (87 cases, 24.4%), segmental group (41 cases, 11.5%) and nodal group (229 cases, 64.1%). The grade of spleen enlargement in the segmental group and the nodal group was significantly greater than that in homogeneous group. The cases with varicose in the segmental group was the most (70.7%), in the nodal group next (17.0%) and in the homogeneous group the least (2.3%). There was significant difference among three groups. In the nodal group, there was ascites in 182 cases (79.5%) and significantly more than that in the segmental group (11 cases, 26.8%) and the homogeneous group (9 cases, 10.3%), and the former significantly more than the latter. There were 68 cases (29.7%) with primary liver carcinoma in the nodal group, and significantly more than that in the segmental group (1 case, 2.4%) and the homogeneous group (5 cases, 5.7%). The cases with hemoglobin decrease in the nodal group were significantly more than that in the homogeneous group. The averages of hemoglobin and platelet in the nodal group and the segmental group were significantly lower than that in the homogeneous group. The cases with SUN increase in the nodal group and the segmental group were significantly more than that in the homogeneous group. The concentration of SUN in the nodal group was significantly higher than that in the homogeneous group.

CONCLUSIONSThere are close relationship between the grouping of liver cirrhosis on basis of CT findings and complications of the cirrhosis. The practice of grouping might be useful for estimating clinical condition
