OBJECTIVETo observe the differences of curative effect of glomerular pathological proteinuria treated with combined therapy of acupuncture and medicine or simple medicine.

METHODSTwo hundred and forty cases of glomerular pathological proteinuria were divided into a combined therapy of acupuncture and medicine group (combined therapy group), a medicine group I and a medicine group II, 80 cases in each group. In combined therapy group, Pishu (BL 20) and Zhishi (BL 52) were punctured by heat-producing needling; Terazosin Hydrochloride, Bisoprolol Fumarate tablets or compound Reserpinum Triamterene tablet were applied with oral administration when accompanied by high blood pressure, to control the blood pressure within 130/80 mmHg. In medicine group I , Renin-Angiotensin-Aldosterone system (RAAS) interruption method was applied to control blood pressure; Benazepril Hydrochloride and Telmisartan were applied with oral administration to keep blood pressure in satisfying level, below 125-130/75-80 mmHg. In medicine group II, placebo was orally taken, and the medicine therapy which was same as that in combined therapy group was applied when accompanied by high blood pressure. Quality low protein and low salt and fat diet were applied in all groups. The Chinese medicine syndrome score, laboratory indices and curative effect were observed in all groups before and after treatment.

RESULTSThe total effective rate was 86.3% (69/80), 61.3% (49/80) and 17.5% (14/80) respectively in combined therapy group, medicine group I and medicine group II, indicating that the curative effect in combined therapy group was superior to that in other groups (P < 0.01, P < 0.05), and it in medicine group I was superior to that in medicine group II (P < 0.01). The Chinese medicine syndrome score was markedly reduced in combined therapy group (P < 0.01), and there was no obvious change in other groups (both P > 0.05). Urinary albumin (UMA) and urinary protein in 24 hours were notably reduced in combined therapy group and medicine group I (all P < 0.01), and it was more obviously in combined therapy group than that in other groups (P < 0.01, P < 0.05). The blood pressure was markedly reduced in all groups (all P < 0.05) after treatment, and there was no significant change in indices of liver and kidney functions (all P > 0.05).

CONCLUSIONThe curative effect of heat-producing needling method is good for treating glomerular pathological proteinuria, better than that of RAAS interruption method.

OBJECTIVETo evaluate the effects of tramadol on the proinflammatory responses in a rat model of incisional pain by investigating its effects on nociceptive thresholds and serum interleukin-6 (IL-6) and IL-2 levels.

METHODSForty-two male Sprague-Dawley (SD) rats scheduled for plantar incision were randomly divided into 7 groups (n=6 in each group). Rats in Group 1 receiving general anesthesia with no incision were served as control; At 30 min before skin incision, Groups 2 to approximately 5 were given 5 ml normal saline or 1, 10, and 20 mg/kg tramadol, respectively, intraperitoneally (i.p.); Group 6 received 10 mg/kg tramadol after operation; Group 7 received 10 mg/kg tramadol before incision, followed by 200 microg/kg naloxone after operation. Mechanical allodynia was measured by electronic von Frey filament to evaluate the nociceptive thresholds 1 h before incision, and 1 h and 2 h after operation. Serum IL-6 and IL-2 levels were measured by enzyme-linked immunosorbent assay (ELISA) 2 h after operation.

RESULTSMechanical thresholds decreased significantly and serum IL-6 level increased significantly after operation in Group 2 compared with control (P<0.01), and these changes were reversed respectively by tramadol in a dose-dependent manner (P<0.05 and P<0.01, respectively). IL-2 level remained unchanged after operation in Group 2, but decreased in Group 3 (P<0.05), then gradually returned to the normal level in Groups 4 and 5. The intraperitoneally injected tramadol (10 and 20 mg/kg) produced a potent and dose-dependent antinocicptive effect on the lesioned paw. The antinocicptive effects of tramadol were partially antagonized by naloxone (200 microg/kg), suggesting an additional non-opioid mechanism.

CONCLUSIONThe results suggest that tramadol could be a good choice for the treatment of pain under the conditions that immunosuppression may be particularly contraindicated.

In order to characterize the molecular epidemiology of HFMD-associated Coxsackievirus A6 (CVA6) in Fujian Province, a total of 1340 specimens from non-EV71 non-CVA16 HFMD patients were collected during 2011-2013. Isolated virus strains were identified and subtyped. Full-length coding regions for the VP1 gene of the predominant serotype CVA6 isolates were amplified and sequenced. Among the 375 non-EV71 non-CVA16 HFMD cases confirmed by virus isolation and molecular subtyping, 182 (48.5%) were found to be caused by CVA6, accounting for 7.9%, 16.2% and 39.6% HFMD-associated enteroviruses in FujianProvince during 2011, 2012, and 2013, respectively. Compared with general features observed in the HFMD epidemic, no difference in CVA6-specificity or severity rates was observed between geographical origins, gender, or age groups. Nucleotide sequence analyses of VP1 genes revealed high diversity levels of 16.2%-18.6% among CVA6 strains from Fujian Province, in contrast to the prototype CVA6 strain, and showed low levels of diversity in the amino acid sequences (4.3%-6.2%). Phylogenetic analysis also indicated that CVA6 isolates from Fujian Province were distinct from the prototype strain and other isolates from abroad; however, it was homologous to domestic strains, although the Fujian isolates clustered into multiple branches. These results suggested that significant changes in the pathogenic spectrum of HFMD in Fujian Province occurred during 2011-2013, as CVA6 was one of the predominant serotypes of HFMD. CVA6 isolates from Fujian Province were co-circulating and co-evolving with other domestic strains as multiple closely related CVA6 transmission chains were observed in Fujian Province overall and within each prefecture.

OBJECTIVETo culture and study the osteogenic characteristics of human bone marrow-derived mesenchymal stem cells (hBMMSCs).

METHODShBMMSCs were separated and cultured from human iliac crest marrow. Growth kinetics of hBMMSCs was studied by growth curve. Under the osteoinductive culture, osteogenic differentiation of hBMMSCs was tested by alkaline phosphatase (ALP). Osteogenic functions of hBMMSCs in vitro and in vivo were also respectively detected by von Kossa stain and by transplanting hydroxyapatite/tricalcium phosphate ceramics (HA/TCP) with hBMMSCs.

RESULTShBMMSCs were cultured successfully. The growth curve of the second passage of BMMSCs indicated that the time of population doublings was about 3.5 days. The results of ALP stain were evident by the significant increase in ALP activity after hBMMSCs cultured in osteoinductive medium. Some mineralized nodules were detected by von Kossa stain at nineteenth day of osteoinductive culture. In vivo assay, histological evalution showed bone formation in 3 months after grafts of HA/TCP with hBMMSCs.

CONCLUSIONSOsteoinductive solution can induce hBMMSCs to differentiate osteogenetic cell lines. Mineralized nodules and bone formation were found in vitro and in vivo assay. The results demonstrate that hBMMSCs have the potential for osteogenesis.

This study aims to investigate the characteristics of genomic variation of pandemic A/H1N1/2009 influenza virus isolated in Fujian Province, China. Complete genome sequence analysis was performed on 14 strains of pandemic A/H1N1/2009 influenza virus isolated from Fujian during 2009-2012. All virus strains were typical low-pathogenic influenza viruses, with resistance to amantadine and sensitivity to neuraminidase inhibitors. Eight genome fragments of all strains were closely related to those of A/California/07/2009 (H1N1) vaccine strain, with > or = 98.2% homology. Compared with the vaccine strain, the influenza strains from Fujian had relatively large variation, and variation was identified at 11 amino acid sites of the HA gene of A/Fujiangulou/SWL1155/2012 strain, including 4 sites (H138R, L161I, S185T, and S203T) involved inthree antigen determinants (Ca, Sa, and Sb). In conclusion, the influenza vaccine has a satisfactory protective effect on Fujian population, but the influenza strains from Fujian in 2012 has antigenic drift compared with the vaccine strain, more attention should therefore be paid to the surveillance of mutations of pandemic A/H1N1/2009 influenza virus.

OBJECTIVETo explore the mutation and amplification of RIT1 gene and their correlation with carcinogenesis of hepatocellular carcinoma (HCC).

METHODSThe polymerase chain reactioindirect sequencing method was used for detecting the mutations in the sequence of all 6 exons in the RIT1 gene of 50 HCC tissues and paratumor tissues. And the amplification of RIT1 gene was examined by fluorescence quantitative polymerase chain reaction method.

RESULTSA nucleotide 241 G --> C substitution in exon 5 of RIT1 gene was detected in one patient's HCC tissue, but not in paratumor tissue; this 241 G --> C substitution leads to Glu81Gln amino acid alteration in the conservative domain binding GTP. A nucleotide G --> C substitution in 5'-UTR (-21 bp from initial codon) was detected in all of the 50 HCC tissues and paratumor tissues, and 2- to 297-fold amplification of RIT1 gene was detected in 11 of 43 qualified cases, the amplification frequency being 25.6%.

CONCLUSIONGene amplification is one of the main activating ways of RIT1 gene in HCC, and its amplification might be correlated with HCC carcinogenesis, while point mutation might be not.

BACKGROUNDWilms' tumor (nephroblastoma) is a cancer of the kidneys that occurs typically in children and rarely in adults. Early diagnosis is very important for the treatment and prognosis of the disease. The aim of our study was to discover and identify potential non-invasive and convenient biomarkers for the diagnosis of Wilms' tumor.

METHODSNude mice were used to construct a Wilms' tumor model by injecting nephroblastoma cells into their bilateral abdomen. We collected 94 serum samples from mice consisting of 45 samples with Wilms' tumor and 49 controls. The serum proteomic profiles of the samples were analyzed via surface-enhanced laser desorption/ionization time-of-flight mass spectrometry. The candidate biomarkers were purified by high-performance liquid chromatography, identified by liquid chromatography-mass spectrometry, and validated using ProteinChip immunoassays.

RESULTSWe finally retrieved two differential proteins (m/z 4509.2; 6207.9), which were identified as apolipoprotein A-II and polyubiquitin, respectively. The expression of apolipoprotein A-II was higher in the Wilms' tumor group than in the control group (P < 0.01). By contrast, the expression of polyubiquitin was lower in the Wilms' tumor group than in the control group.

CONCLUSIONApolipoprotein A-II and polyubiquitin may be used as potential biomarkers for nephroblastoma in children, and the analysis of apolipoprotein A-II may help diagnose and treat Wilms' tumor.
