BACKGROUND:Bone marrow mesenchymal stem cel s are likely to repair renal injury by differentiating into renal parenchymal cel s. OBJECTIVE:To explore the effect and mechanism of bone marrow mesenchymal stem cel s in the renal repair after mesangial proliferative glomerulonephritis. METHODS:Thirty Sprague-Dawley rats were randomized into normal group, model group and treatment group (n=10 per group). Model group and treatment group were treated with tail vein injection of mouse anti-rat monoclonal antibody Thy1.1 to prepare mesangial proliferative glomerulonephritis models. One week after modeling, rats in the treatment group were given 2×106 bone marrow mesenchymal stem cel s via the tail vein, and rats in the other two groups were given the same volume of normal saline. Two weeks after transplantation, urinary protein, urea nitrogen, creatinine levels were detected;hematoxylin-eosin staining was used for observing pathological changes of the renal tissue under microscope;and the expression of transforming growth factor beta 1 was detected by immunohistochemistry method. RESULTS AND CONCLUSION:The levels of urinary protein, urea nitrogen and creatinine as wel as the expression of transforming growth factor beta 1 in the renal tissue arranged in descending order were listed as fol ows:model group>treatment group>control group, and there were significant differences among three groups (P<0.05). In the model group, diffuse glomerular hyperplasia was observed with the presence of increased extracel ular matrix, partial glomerular sclerosis, and interstitial infiltration of inflammatory cel s;in the treatment group, glomerular hyperplasia, mesangial proliferation and inflammatory cel infiltration were al mitigated compared with the model group. Therefore, bone marrow mesenchymal stem cel transplantation may contribute to renal repair after mesangial proliferative glomerulonephritis, by inhibiting overexpression of transforming growth factor beta 1 in the kidney.

Objective To explore the effect of applying problem-based learning(PBL)in clin-ical anesthesiology demonstration for clinical undergraduates. Methods Eighty-nine 2009 clinical undergraduates were divided into two groups:experimental group and control group. Students in ex-perimental group received PBL while those in control group received traditional teaching. The effect was evaluated according to the results of case examination and investigation table. The results were analyzed by X2 test. Results Most students (42/45) answered questions correctly in experimental group while only 30 of 44 students(30/44)did in control group(P<0.05). Concerning the results of investigation,PBL had more advantages than traditional teaching method in the following 5 aspects:self-studying ability(86.7%,39/45),clinical thinking ability(73.3%,33/45),information seeking ability (75.6%,34/45),expressing ability (82.2%,37/45),communicating between students (75.6%, 34/45)(P<0.05). Conclusions PBL has evident advantages in anesthesiology clinical demonstration. It can inspire students,cultivate abilities,enhance critical thinking and finally improve teaching effect.

A capillary electrophoretic method was developed for the separation of enantiomers of naphthylgly-cidic ether(NGE). Several cyclodextrins(CDs) were applied as the chiral selectors and it was found that the ionic modified highly sulfated cyclodextrin(HS-β-CD) could give satisfactory enantioselectivity. In addition,the effects of the pH value of the buffer system,the concentration of the HS-β-CD,capillary temperature and the running voltage on the chiral separation were investigated systematically. The result showed that under the optimized conditions of pH 2. 5,20 mmol/L H_3PO_4-triethanolamine buffer containing 2% highly sulfated cyclodextrin ( HS-β-CD) at capillary temperature 20℃ in the reversed polarity voltage of - 18 kV,the enantiomers of naphthylglycidic ether were baseline separated. This method is simple,precise and can be applied to the chiral separation of naphthylglycidic ether enantiomers and determination of enantiomers excess(ee,% ).

Objective To investigate the types,incidence rate and related factors of adverse drug reactions(ADRs)in pa-tients with concomitant multi-drug resistant pulmonary tuberculosis(MDR-TB)and diabetes mellitus(DM)and those with only MDR-TB in an attempt to improve the surveillance of patients with both MDR-TB and DM.Methods A total of 359 MDR-TB patients who were diagnosed in the first batch of the 5th round of China Global Fund project in Wuhan city from December 1, 2006 to June 30,2014 and enrolled in the whole supervision process were retrospectively analyzed.They fell into MDR-TB(DM+)group(n=74;20.6%,74/359)and MDR-TB(DM -)group(n=285;79.4%,285/359).The incidence and the occurrence time of ADRs were compared between the two groups.The patients with MDR-TB(DM +)group were divided into two sub-groups in terms of the occurrence of ADRs.The treatment success rate and the effects of age,body mass index,plasma albumin level before treatment,fasting blood glucose level,smoking,alcohol consumption and other diseases on ADRs were investiga-ted.Results ①The incidence of ADRs in MDR-TB(DM+)group(39 cases,52.7%)was not significantly different from that in MDR-TB(DM -)group(141 cases,49.5%)(c2=0.245,P>0.05). ② The incidence of hypothyroidism(c2=6.08,P<0.05), hypokalemia(c2=12.37,P<0.05)and QT interval prolongation(c2=4.32,P<0.05)was significantly higher in MDR-TB(DM+)group than in MDR-TB(DM -)group during the treatment. ③ The lower body mass index(F=6.289,P<0.05),the de-creased level of plasma albumin(F=9.743,P<0.05),concomitant chronic liver disease(c2=6.000,P<0.05)and other chronic diseases(c2= 4.125,P<0.05)were associated with ADRs in patients with both MDR-TB and DM.No associations of sex,age, mean fasting blood glucose level,smoking,alcohol consumption,duration of diabetes,initial treatment and retreatment,number of resistant drugs was found with ADRs. ④There were 17 cases(43.6%,17/39)cured in ADRs group and 25 cases(71.4%,25/35)cured in non-ADRs group,with significant difference found(c2=5.825,P<0.05).Conclusion The patients with concomi-tant MDR-TB and DM are more likely to develop hypothyroidism,hypokalemia,and QT interval prolongation during the treat-ment,and need periodic monitoring and adjustment of medication.Those with the worse nutritional status(lower BMI and plas-ma albumin level)and other concomitant diseases(such as chronic liver disease,etc.)are more likely to have ADRs.Those with ADRs tend to have lower success rate of cure,and they are more likely to suffer treatment failure,loss to follow-up,interruption of treatment and so on.

HIV p24 core protein can induce both cellular and neutralizing antibody responses.HIV-1 CA-virus-like particles(VLPs)vaccines provide a promising approach for the development of an effective vaccination strategy against HIV infection.Rhizosecreion of the recombinant proteins provides a new manufacturing platform that can simplify the extraction and purification procedure.Lycium barbarum L.was transformed by Agrobacterium tumefaciens EHA105 harboring the plant expression vector pCAMBIA1305.2-MA4-CA with a GRP signal peptide and MA4-CA fusion gene.Transgenic hairy roots were induced and cultivated in hydroponic culture.Western blotting indicated that the recombinant CA proteins were present in two forms,a glycosylated monomer(37 kDa)and a dimer(50 kDa)in the roots and hydroponic medium.It appeared from the present immunohistochemical data that the recombinant CA proteins fused with GRP signal peptide were confined to the cytoplasm,cell wall and intercellular space,indicating targeting into the secretory pathway.It demonstrated for the first time the rhizosecretion of HIV-1 recombinant capsid protein in Lycium barbarum L.hairy roots,and may offer a novel method for expressing HIV-1 CA-VLPs vaccines in plants.
