OBJECTIVETo compare the difference in the efficacy on cervical type of cervical spondylosis (CS) between the combined treatment of sword-like needle and chiropractic spinal manipulation (the combined therapy) and the simple chiropractic spinal manipulation.

METHODSOne hundred and thirty-eight cases of cervical type of CS were randomized into a combined therapy group (76 cases) and a simple chiropractic spinal manipulation group (62 cases). In the combined therapy group, the sword-like needle therapy was applied at Fengchi (GB 20), Tianzhu (BL 10) and Jiaji (EX-B 2) C3-C5. The chiropractic spinal manipulation was used in combination. In the chiropractic spinal manipulation group, the simple chiropractic spinal manipulation was adopted. The treatment was given once every other day in the two groups, 10 days made one session. One session of treatment was required. Visual analog scale (VAS) score was observed before and after treatment in the two groups and the efficacies were compared between the two groups.

RESULTSVAS score after treatment was reduced obviously as compared with that before treatment in the patients of the two groups (both P < 0.01) and VAS score after treatment in the combined therapy group was lower than that in the simple chiropractic spinal manipulation group (1.50 +/- 0.58 vs 1.87+/-1.05, P < 0.01). In the combined therapy group, 48 cases were cured, 20 cases remarkably effective, 8 cases improved and 0 case failed. In the chiropractic spinal manipulation group, 30 cases were cured, 16 cases remarkably effective, 15 cases improved and 1 case failed. The overall efficacy in the combined therapy group was better than that in the chiropractic spinal manipulation (P < 0.05).

CONCLUSIONThe sword-like needle therapy combined with chiropractic spinal manipulation relieve effectively pain in cervical type of CS and the efficacy is superior to the simple chiropractic spinal manipulation.

OBJECTIVETo explore the technique of induction of polyploidy in Salvia bowleyana by colchicine treatment.

METHODThe three kinds of explant of bud, leaf and calli were induced by colchicine treatment.

RESULTThe induction effects were better when the calli was treated by colchicines (15 mg x L(-1)) and the leaf was pre-cultured for one week. The doubling rate was 33.33%, while the majority were wholy doubled plants, and the leaves were thicker and broader, the color was darker, the root was thicker and the stoma size was obviously bigger than the diploid plants. The number of chromosome were 8 to 64. Isoenzyme analysis showed that the enzyme activities between the polyploid and the diploid plants were quite different.

CONCLUSIONInduction of polyploidy by colchicine treatment is efficacious. The part of the doubled plants were identified as homologmous tetraploids.

Objective To observe the change in cardiac shape and heart function and evaluate the effect of self-treatment on patients with Keshan disease by echocardiography. Methods To check the 31 patients with Keshan disease before the self-treatment, and follow them up in the 3rd and 6th months after self-treatment by echocardiography. The left atrium diameter(LAd), left ventricular end-diastolic diameter(LVEDd), the thickness of interventricular septum in end-diastolic(IVSTd), the thickness of LV posterior wall in end-diastolic (LVPWTd), left ventricular mass(LVM), left ventricular mass index(LVMI), left ventricular ejection fraction(LVEF) and mitral valve flow E/A ratio(E/A) were measured. Results The LAd[(35.8±5.1)ram] and LVPWTd[(9.3±1.0)mm] obviously decreased in the 3rd month after serf-treatment compared with prior self-treatment [ (37.0±5.0), (9.9± 1.2)mm](P<0.05). The LAd[(34.5±5.0)mini, IVSTd[(9.5±1.3)mm], LVEDd[(50.2±7.7)mm], LVPWTd [(8.7±1.1)mm], LVM[(196.1±87.2)g] and LVMl[(126.5±56.4)g/m2] obviously decreased in the 6th month after self-treatment compared with prior self-treatment [(37.0±5.0), (10.2±1.5), (51.3±8.1), (9.9±1.2)mm, (230.4±95.5)g, (144.0±54.6)g/m2] and in the 3rd month after self-treatment [(35.8±5.1)mm, (10.2±1.4) ram, (51.1±8.1)nun, (9.3±1.0)mm, (219.4±82.5)g, (136.8±50.0)g/m2] (P<0.05). The results of the mitral valve flow E/A ratio and LVEF in the 3nt month after self-treatment [1.0±0.5, (59.4±13.3)%] were increased compared with the prior self-treatment[0.9±0.5, (58.1±15.6)%], and the results in the 6th month after self-treat- ment[ 1.0±0.4, (60.7±13.6)%] were further inereased compared with before, but there was no signifieant differ- ence(P0.05). Conclusions Self-treatment of Keshan disease patients can improve the heart function by pre- venting left ventrieular remodeling and reversing. Echocardiography can be used as an essential technique to evalu- ate the effect of self-treatment on Keshan disease patients.

This article reports a case of limb-girdle muscular dystrophy type 1B (LGMD1B) caused by a novel splicing heterozygous mutation in the LMNA gene. The proband presented with progressive aggravation of weakness in walking. There was no atrophy of the scapular muscles and the lower-extremity proximal muscles, with normal muscle tension of the extremities, grade 4 muscle strength in the upper and lower extremities, and positive Gower sign. The level of creatine kinase was 779 U/L. Muscle hematoxylin-eosin staining showed muscular dystrophy, and there was no significant reduction in the expression of Lamin A protein. Second-generation sequencing revealed a novel splicing heterozygous mutation, c.810+2T>C, in the LMNA gene, while this locus was normal in his parents. GERP++RS software predicted that the mutation site was highly conservative. Human Splice Finder and Spliceman software predicted that the mutation might be a pathogenic mutation. ExPASy software predicted that the new amino acid sequence became shorter. There were two sequences of mRNA in the patient's muscle: one was the normal sequence, which accounted for 92.2%; the other was partial intron 4 retention, which was the abnormal splice variant accounting for 7.8%. LGMD1B is a type of autosomal dominant inherited myopathy caused by a mutation in the LMNA gene located on the autosomal 1q22. This study extends the mutation spectrum of the LMNA gene and provides help to the diagnosis of LGMD1B.

Objective To investigate the effect of Xinma Granules on respiratory mucosal immune function in chronic asthmatic mice.Methods Fifty female BALB/C mice were randomly divided into normal group,model group,low-dose Xinma Granules group,high-dose Xinma Granules group and Dexamethasone group,with 10 mice in each group.Except for the normal group,the mice in the other groups were sensitized and challenged with ovalbumin(OVA)to establish a chronic asthma model.After corresponding treatment,the levels of secretory immunoglobulin A(sIgA)and immunoglobulin E(IgE)in bronchial lavage fluid were measured by enzyme-linked immunosorbent assay(ELISA).The pathological changes of lung tissue were observed by hematoxylin-eosin(HE)staining.The expression of E-cadherin in lung tissue was detected by Western Blot.Results HE staining showed obvious airway inflammation in asthmatic mice.The concentration of sIgA in the bronchial lavage fluid of the model group was lower than that of the normal group(P＜0.05);the concentration of sIgA in the high-dose and the low-dose of Xinma Granules groups and the Dexamethasone group was higher than that in the model group(P＜0.05);the concentration of IgE in bronchial lavage fluid of model group was higher than that of normal group(P＜0.05);the concentration of IgE in the high-dose and the low-dose Xinma Granules groups and the Dexamethasone group was lower than that in the model group(P＜0.05).The relative expression of E-cadherin protein in lung tissue of the model group was lower than that of the normal group(P＜0.05);the relative expression of E-cadherin protein in lung tissue of mice in the high-dose and low-dose Xinma Granules groups and Dexamethasone group was higher than that in model group(P＜0.05).The improvement effect on above various indexes in high-dose Xinma Granules group and Dexamethasone group were superior to that in low-dose Xinma Granules group(P＜0.05),the differences between the both groups were statistically insignificant(P＞0.05).Conclusion Xinma Granules may improve the airway mucosal immune function of asthmatic mice by improving airway inflammation,increasing the concentration of sIgA in the respiratory tract,and enhancing the expression of E-cadherin protein in the respiratory tract.

OBJECTIVE: To investigate multilineage-differentiating stress-enduring (Muse) by immunomagnetic bead screening from Wharton's jelly mesenchymal stromal cells(WJ-MSCs), and explore transplantation of Muse cell for safety and effectivensess of sub acute cord injury in rats. METHODS: Donated Wharton's Jelly-mesenchymal stromal cells (WJ-MSCs) were successfully derived from a human umbilical cord by a series of procedures namely physical isolation of Wharton's Jelly from cord membrane, collagenase and trypsin treatment and density gradient centrifugation. Magnetic activated cell sorting was performed to specifically select SSEA3+ Muse cells, and flow cytometry and immunocytochemistry were used to identify further. In vivo, spinal cord contusion injury model in rats was induced by NYU-III impactor, and were randomly divided and equally into four groups, namely group A (sham), group B (control), group C (Non-Muse cells transplantation) and group D (Muse cells transplantation). Laminectomy was conducted in group A but no spinal cord contusion injury. Laminectomy and cord injury were performed in group B, C and D, 10 g trip rod was freely falling down from 12.5 mm. Two weeks later, group B, C and D were received PBS injection, Non-Muse cells transplantation and Muse cells transplantation respectively, four-point injection were performed in each cord with totally 4×10⁵ cells. BBB scores were evaluated on 1 day, 1, 2, 3, 4, 5 and 6 week after injury. Four weeks after cell transplantation, the rats were sacrificed, and immunohistochemistry were carried out to observe survival, migration and differentiation of the injected cells. RESULTS: The expression of CD105, CD90 and CD73 were over 99.5% in the derived WJ-MSCs population, but CD45 and CD14 were lower than 0.5%, positive rate of SSEA3+ was 1.46% under flow cytometer, However, after MACS sorting, the percentage of 92.0% Muse cells expressed SSEA3 and CD105, and immunohistochemistry results of SSEA3 showed typically membrane morphology with special processes. In vivo, BBB scores was 21 in group A at different time points. One-way ANOVA and LSD analysis showed that BBB scores in group C and D were significantly higher than that in group B (=0.004, 0.002), but there was no significantly difference between group C and D. Further intra-group paired t test showed that BBB score was significantly higher at 4 weeks than that 3 weeks in group C (=0.005). However, in group D, BBB scores were significantly higher at 4 and 6 week than those at 3 and 5 weeks, values were 0.005 and 0.016 respectively. Immunohistochemistry results showed that both Muse cells and Non-Muse cells could survive for 4 weeks in rats and they migrated from the four-point injection to injury site. But there showed more Muse cells survival than Non-Muse cells in the cord. CONCLUSIONS Immunomagnetic bead screening is efficient to select large number of purified SSEA3+ Muse cells. Muse cells could survive and target-migrate in injured cord to improve BBB scores continuously. Muse cells are a novel kind of seed cells in the spinal cord injury treatment.

Objective To better understand the prevalence and geographic distribution of genotypes/subtypes on HCV and the relationship between HCV genotypes/subtypes and HIV infection disease progression in the HIV-1/HCV co-infected individuals living in high HIV-1 prevalent areas in China. Methods 186 plasma samples were collected from HIV-1 seropositive individuals infected through paid blood donors (PBD), injecting drug users (IDUs) or sexual contact, living in most severely affected provinces, Henan, Yunnan, Xinjiang, Jilin and Liaoning provinces. Samples with HCV viral load >1000 cop/ml were amplified by RT-nested PCR, sequenced and phylogenetically analyzed for genotyping/subtyping of HCV. HIV-1, HCV viral loads and CD4 T lymphocytes were measured for all subjects. Results (1) HCV were identified as 1 a (1.7%), 1 b (39.9%), 2a (17.9%), 3a (10.4%), 3b (15.6%), 6a (1.2%), 6n (6.4%), and a newly unclassified subtype (7.5%). HCV 2a and lb subtypes predominated in PBD in Henan, 3a and 3b in IDUs in Xinjiang and Yunnan, and 6 genotype/subtypes in IDU in Yunnan. (2) There were no significant differences in CD4 T cell counts among the different HCV subtypes. (3) The viral load of HCV RNA in lb subtype was higher than that of non-1b subtype, however, no significant differences in HIV-1 viral loads and CD4 T cell counts were found between Ib and non-1b subtype. Both HIV and HCV viral loads were lower in 2a than non-2a subtype. Conclusion The prevalence of HCV genotype/subtype in HIV-1/FICV co-infected individuals was associated with geographic areas and transmission routes. HCV subtypes had no direct correlation with HIV infection disease progression.

Background:Reduced expression of tripartite motif-containing 3 (TRIM3) has been reported to be involved in the pathogenesis of human glioblastoma.In our previous research,we found that TRIM3 expression was markedly reduced in human primary hepatocellular carcinoma (HCC) tissues and that low TRIM3 expression was associated with short survival of HCC patients.However,the role of TRIM3 in liver cancer remains unknown.This study aimed to investigate the function of TRIM3 in liver cancer cells.Methods:The protein levels of TRIM3 in five liver cancer cell lines (SK-Hep1,Hep3B,Huh7,HepG2,Bel-7402) and one normal liver cell line (L02) were detected with Western blotting.HepG2 and Bel-7402 cells with IowTRIM3 expression were infected with recombinant lentiviruses overexpressing TRIM3 (LV-TRIM3),whereas Huh7 and Hep3B cells with high TRIM3 expression were transfected with TRIM3-targeted small interfering RNA (siTRIM3).The functions of TRIM3 in the proliferation,colony formation,cell cycle,migration,invasion,and apoptosis of the above cell lines were examined.The effect of TRIM3 on tumor growth and metastases in nude mice was also investigated.Results:TRIM3 was overexpressed in HepG2 and Bel-7402 cells with LV-TRIM3 infection,which further reduced proliferation,colony formation,migration,and invasion of both cell lines.Cell cycle analysis showed thatTRIM3 overexpression induced G0/G1 phase arrest in HepG2 and Bel-7402 cells.Moreover,apoptosis was not increased in HepG2 or Bel-7402 cells overexpressing TRIM3.Contrarily,silencing TRIM3 expression in Huh7 and Hep3B cells by siTRIM3 led to significantly decreased percentages of both cells in the G0/G1 phase and promoted cell proliferation,colony formation,migration,and invasion.In vivo experiment results confirmed thatTRIM3 overexpression suppressed tumor growth and metastasis.Conclusions:TRIM3 plays a tumor-suppressing role in the regulation of liver cancer development by reducing cell proliferation through cell cycle arrest at the G0/G1 phase.

OBJECTIVETo investigate the clinical efficacy, surgical indications and postoperative complications of mid urethral sling procedures in treatment of female stress urinary incontinence.

METHODSA multicenter clinical trial was conducted from April 2002 to April 2008 in five hospitals, 304 cases of genuine stress urinary incontinence and 8 cases of mixed incontinence were included. TVT procedures were carried out in 134 patients, TVTO procedures in 167 patients, Monarc procedures in 11 patients. Perioperative evaluations included: operating time, bleeding volume, and perioperative complications. Operative efficacy was classified into three categories: cure, improved and failure and evaluated before discharge, 3 months after surgery and then every year.

RESULTSTVT group had longer operating time [(18.5 + or - 9.6) min] and more bleeding volume [(32.2 + or - 12.6) ml] than those in TVTO group [(11.5 + or - 3.1) min, (12.8 + or - 8.5) ml] and in Monarc group [(11.1 + or - 2.6) min, (12.3 + or - 3.5) ml] with P < 0.05. Monarc and TVTO procedures had higher cure rates and improve rates comparing with TVT, but the differences were of no significance. The cure rate (95.7%) in patients with genuine stress incontinence were significantly higher than that in patients with mixed incontinence (37.5%). No significant differences of total intra- and postoperative complications were noted for all of the three procedures. However, bladder injury tended to occur in TVT group and obturator nerve injury and vaginal injury tended to occur in TVTO group. Transient voiding dysfunction and urinary retention were the most common complications.

CONCLUSIONSMid urethral sling procedures have excellent clinical outcomes in the treatment of female stress urinary incontinence.
