Objective: To evaluate the effect of Tai Chi and Qigong on patients with lumbar disc herniation (LDH). Methods: Relevant data were retrieved from nine English and Chinese databases, including Cochrane Library, PubMed, and Wanfang Data, etc. from inception to June 2024. All published randomized controlled trials assessing the effect of Tai Chi and Qigong on visual analog scale (VAS), Japanese Orthopedic Association (JOA) score, and other health indicators in participants with LDH compared to usual medical care or other treatments were included. Grey literature, trials involving the pushing of hands (Tui Shou) or Tai Chi with weapons, and trials with co-interventions (Tai Chi/Qigong plus another treatment) were excluded. Methodological quality was analyzed using the Cochrane risk of bias tool, and evidence quality was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) tool. Results: Fourteen trials (954 patients) were included in this study. Tai Chi and Qigong were associated with lower VAS pain scores (standardized mean difference −0.55, 95% confidence interval [CI] −0.95 to −0.15, P = .01), higher JOA scores (mean difference [MD] 4.40, 95% CI 2.62 to 6.18, P < .001) and straight leg raise test results (MD 9.40°, 95% CI 7.64 to 11.15, P < .001) in patients with LDH. Furthermore, compared with usual care, Tai Chi and Qigong showed enhanced effects on pain and JOA scores. When compared to other exercises or massage, the effect on pain scores was similar but that on JOA scores was significant. Conclusions Tai Chi and Qigong may have favorable effects on VAS pain and JOA scores compared with usual care, and on JOA scores compared with other exercises or massage in patients with LDH. Given the overall poor quality of the evidence, the results of current study should be interpreted cautiously.

OBJECTIVETo study the the relationship between lymphatic vessel density (LVD) and distal intramural spread (DIS), and evaluate the value of LVD in determining the length of distal resection in low rectal cancer.

METHODSNinety-two samples from patients undergone curative resection of low rectal cancer were studied. DIS was detected by HE stain. LVD was examined by immunohisto-chemical LYVE-1 (lymphatic vessel endothelial hyaluronan receptor). The association of LVD with DIS and other clinicopathological factors were examined.

RESULTSDIS (range 0.1-2.4 cm, mean 0.31 cm) was present in 44(47.8%) patients with low rectal cancer, including 23(52.3%) cases with cancer emboli in lymphatic vessels. LVD of peritumoral lesion was significantly higher than that of intratumoral lesion. LVD of DIS subgroup was significantly higher than that of non-DIS subgroup. Positive correlation was found by rank correlation test between the length of DIS and the LVD at peritumor tissue in DIS group (n=44, r=0.755, P<0.01). LVD was also positively correlated with the infiltration extent, lymphatic invasion and lymph node metastasis.

CONCLUSIONSLymphangiogenesis plays an important role in rectal cancer metastasis and cancer emboli in lymphatic vessels is the most common modality of DIS. The LVD is positively correlated with DIS, which may be helpful to determine the distal clearance length of rectal cancer.

OBJECTIVETo characterize the clinical features of Chinese HNPCC families and to screen the mutations of a poly-(A)8 tract in M3 cholinergic receptor gene in these families.

METHODSThe clinical features of 15 Chinese HNPCC families were characterized. Genomic DNAs from 15 probands were prepared. PCR and direct DNA sequencing analysis were employed to examine the mutations of a poly-(A)8 tract in exon 8 of M3 cholinergic receptor gene.

RESULTSTotal 55 cancer patients were found in 15 families including 41 cases of colorectal carcinoma with an average of 2.73 colorectal carcinomas developed per family. Thirty out of forty-one (73%) patients were diagnosed before age of 50 years. Proximal colon was involved in 51% of patients, while anus and rectum were 40 %. Synchronous and metachronous multiple colorectal cancers developed in 5 patients (12%). Two thirds of families belonged to Lynch II syndrome, and total 18 extracolonic malignancies in 14 patients were identified. Gastric carcinoma was the most common extracolonic types. In 15 HNPCC probands, no mutation was detected in the poly-(A)8 tract of exon 8 of M3 cholinergic receptor gene.

CONCLUSIONM3 cholinergic receptor gene might have little relation with HNPCC in Chinese population. The criteria for Chinese HNPCC are useful and practical in clinical application.

OBJECTIVE: To localize the gene of autosomal dominant familial dilated cardiomyopathy with conduction defect. METHODS: A Chinese family which was diagnosed as dilated cardiomyopathy with conduction defect was studied. Venous blood (3 - 5 mL) from some family members was collected, and genomic DNA was extracted from the blood. Then whole genome wide scan was performed after excluding the known markers on the candidate loci (CMD1A, CMD1 E, CMD1F, and CMD1H) by two-point linkage analysis. RESULTS: No significant evidence for linkage was found in the two point linkage analyses to the known markers in the analyzed family. And the whole genome wide scan showed the maximum LOD score reached 2.68 at marker D3S1614 ( at recombination fraction theta = 0). CONCLUSION The related gene in this kindred is located on 3q26 other than on CMD1A, CMD1H, CMD1E, and CMD1F.

To explore the hematopoietic reconstitution and transplantation-related complications of two units of unrelated umbilical cord blood combined transplantation for the treatment of adult hematologic malignancies, one adult patient with chronic myelogenous leukemia received two units of unrelated umbilical cord blood combined transplantation. The conditioning regimen was busulfan and cyclophosphamide (Bu-Cy). GVHD prophylaxis regimen consisted of mycophenolate mofetil (MMF), cyclosporine A (CsA) and methotrexate (MTX). The patient received total nucleated cells 4.63 x 10(7)/kg with CD34+ cells 8.34 x 10(5)/kg. Engraftment was documented by the analysis of short tandem repeat with polymerase chain reaction (STR-PCR). The results showed that the STR-PCR analysis for peripheral blood at day 31, 46 and 71 after transplantation suggested that one of two units of cord blood were completely engrafted. The ANC > 0.5 x 10(9)/L in the patient occurred at day 23, blood platelet counts > 20 x 10(9)/L at day 33 and > 50 x 10(9)/L at day 47. The Philadelphia chromosome and bcr/abl fusion gene of the patient also turned to negative after engraftment. Acute GVHD grade II occurred at day 13 and cured after treatment. It is concluded that umbilical cord blood can be used in adult hematopoietic stem cell transplantation. Two or more units umbilical cord blood combined transplantation might be the way to solve the problem of the low counts of nucleated cells when be used for adult.

OBJECTIVETo investigate the mutation of 5' non-coding region of bcl-6 gene in germinal center B-cell (GCB) subtype of diffuse large B-cell lymphoma (DLBCL).

METHODSt(14;18) detection and immunohistochemical staining (EnVision method) were performed in 60 cases of DLBCL, which were divided into GCB and non-GCB subtypes. Polymerase chain reaction (PCR), single-strand conformation polymorphism and direct DNA sequencing were used to identify mutations in the 5' non-coding region of the bcl-6 gene.

RESULTSSeven of 60 cases showed t(14;18) translocation in the major breakpoint region. Using minimally acceptable criteria, 18 of 60 cases were probably to be germinal centre derived. Bcl-6 mutations were detected in 12 of 60 cases (20.0%) of DLBCL, with a significantly higher frequency in the GCB subgroups (7/18) than in the non-GCB subgroups (11.9%, 5/42). Bcl-6 mutations occurred most frequently in +363 and +469 sites. An association of bcl-6 mutation and GCB subgroup was obtained.

CONCLUSIONSThe 5' regulatory region of the bcl-6 gene underwent less frequent somatic hypermutation during lymphomagenesis than the results of previous reports. Bcl-6 mutation occurred mostly in the GCB subtype and detection of t(14;18) seems helpful in the classification of DLBCL.
