OBJECTIVETo study therapeutic effects of comprehensive traditional Chinese medicine therapy for preventing postsurgery stiffness after operation for terrible triad of the elbow.

METHODSFrom December 2008 to December 2013,32 patients with elbow triad were randomly divided into two groups: therapy group and control group. There were 17 patients in control group including 12 males and 5 females with a mean age of (41.0 ± 7.1) years old. The patients in control group were received the past procedure therapy. There were 15 patients in therapy group, including 10 males and 5 females with a mean age of (41.3 ± 7.6) years old. The patients in therapy group were received comprehensive traditional Chinese medicine therapy, including passive exercise training at early stage (0 to 2 weeks after operation), transition from passive to active exercise training at middle stage (3 to 4 weeks after operation), and active exercise training at late stage (5 to 12 weeks after operation). Other treatment methods, such as orally taking or externally use of Chinese herbal medicine, manipulation and physiotherapy, were used at all stages. The Mayo Elbow Performance Score, patient satisfaction and complications were evaluated and analyzed.

RESULTSAll the patients were followed up, and the mean duration was 7.5 months. There were no complications such as internal fixation loosing, obvious displacement fracture and heterotopic ossification occurred. The Mayo score and patient satisfaction in therapy group were higher than those in control group (t = 12.78, P = 0.00; χ2 = 8.719, P = 0.003). Seven patients needed reoperation in control group, compared with 1 patient in therapy group (χ2 = 4.626, P = 0.032).

CONCLUSIONThe comprehensive traditional Chinese medicine therapy is effective to prevent postoperative stiffness after operation for terrible triad of the elbow by using different methods at different stages, which is worthy of spread and application.

OBJECTIVETo observe the effect of total coptis alkaloids (TCA) on beta -amyloid peptide (A beta 25-35) induced learning and memory dysfunction in rats, and to explore its mechanism.

METHODSForty male Wistar rats were randomly divided into four groups: the control group, the model group, the TCA low dose (60 mg/kg) group and the TCA high dose (120 mg/kg) group, 10 in each. A beta 25-35 (5microl, 2 microg/microl) was injected into bilateral hippocampi of each rat to induce learning and memory dysfunction. TCA were administered through intragavage for consecutive 15 days. Morris Water Maze test was used to assess the impairment of learning and memory; concentration of malondialdehyde (MDA) in cerebral cortex was determined by thiobarbituric acid reactive substance to indicate the level of lipid peroxidation in brain tissues; activity of manganese-superoxide dismutase (Mn-SOD) in cerebral cortex was determined by xanthine-oxidase to indicate the activity of the enzyme; and NF- kappa B protein expression in cerebral cortex was measured by SP immunohistochemistry.

RESULTS(1) Morris Water Maze test showed that, during the 4 consecutive days of acquisition trials, the rats in the model group took longer latency and searching distance than those in the control group (P<0.01), which could be shortened by high dose TCA (P<0.05); during the spatial probe trial on the fifth day, the rats in the model group took shorter searching time and distance on the previous flat area than those in the control group (P<0.01), which could be prolonged after TCA treatment (for low dose group, P<0.05; for high dose group, P<0.01). (2) Analysis of cerebral cortical tissues showed that, compared with the control group, MDA level got significantly increased and Mn-SOD activity decreased in the model group (both P<0.01). After having been treated with TCA, the MDA level got significantly decreased (P<0.05 and P<0.01 respectively for low and high dose group), while relative increase of Mn-SOD activity only appeared in high dose group (P<0.05). (3) Immunohistochemistry analysis showed the protein expression of NF- kappa B got significantly increased after modeling, while high dose TCA can significantly inhibit it.

CONCLUSIONTCA could improve A beta 25-35 induced dysfunction of learning and memory in rats, and its protective mechanism is associated with its actions in decreasing MDA level, increasing Mn-SOD activity and inhibiting the expression of NF-kappa B in cerebral cortex.

Soil salinity is an important issue, as most crop plants are low in salt tolerance. Salt tolerance, a complex, multifactorial, and multigenic process, has been known to be a quantitative trait. The identification of the salt stress responsive genes or salt tolerance genes is essential for the breeding programs. Most recent efforts have been focused on the products of structural genes (transport proteins, ion channels, enzymes of solute synthesis) while little attention were paid to the regulatory aspects of these proteins. Since the first aquaporin gene from plants was cloned and functionally expressed in 1993, there has been a growing interest in the molecular biology of MIPs (membrane intrinsic proteins) and their bearing on the biophysics of water flow across plant membranes. In the last decades, studies on Mangroves, a special kind of wood plants, grow in high-salt and flooding conditions have been concentrated almost exclusively on their physiological and ecological characteristics. Kandelia candel, one of the dominant species of mangroves along the Chinese coast, lacks salt glands or salt hairs used for removal of excess salt in other mangroves. This makes K. candel a perfect model to study the molecular mechanism of salt tolerance in mangrove plants. Using cDNA RDA, a cDNA-specific modification of genomic representational difference analysis, a series of salt responsive genes of Kandelia candel were cloned. Among these gene fragments, a 183 bp fragment (termed as SRGKC1) encoding a tonoplast intrinsic protein (TIP) in Kandelia candel (KCTIP1) was identified. Based on the sequence of SRGKC1, two gene specific primers were designed, and the 3' and 5' end of the KCTIP1 gene were obtained using the SMART RACE cDNA Amplification Kit. RACE products were purified from low-melting agarose, and sequenced directly with GSPs as the sequencing primers. A 500-bp fragment corresponding to the 3'end of this gene was obtained using the GSP1 primer, and a 690 bp fragment corresponding to the 5' end of this gene was obtained using the GSP2 primer. Two primers that flank the putative open reading frame (ORF) were designed to obtain the cDNA containing the complete ORF by RACE PCR reaction. The full-length cDNA of KCTIP1, containing a 756 bp open reading frame (ORF), was approximately 1.1 kb; the start codon was located at the nucleotides of 99-101 and stop codon at the nucleotides of 855-857 followed by a poly (A) tail. The KCTIP1 cDNA sequence in this research was released in GenBank with accession number AF521135. Using ExPASy Proteomics tools provided by EMBL, the isoelectric point and MWt of KCTIP1 are estimated as 5.77 and 26.3 kD respectively. Transmembrane prediction analysis revealed the deduced KCTIP1 protein sequence contains six transmembrane regions at amino acid residues of 20 - 42, 57 - 79, 86 - 108, 113 - 135, 142 - 164 and 217 - 239. Two highly conserved asparagine-proline-alanine (NPA) motifs were located at 85 - 87 and 199 - 201 amino acid residues respectively. KCTIP1 is also predicted to contain the Cys residue (Cys 118) that are shown to confer Hg-sensitivity in Arabidopsis gamma-TIP and delta-TIP. Similarity analysis showed that KCTIP1 shared 77% - 79% amino acid sequence identity with the TIPs from Vitis berlandieri, Brassica oleracea and Arabidopsis thaliana. Expression analyses indicated that KCTIP1 had different expression among species of Mangroves. Expressions of KCTIP1 in Kandelia candel, Rhizophora apoculata and Ceriops tagal were suppressed by salt, and were insensitive to salt stress in unknown species of Mangroves. Previous studied showed that salt conditions might result in large and rapid changes in extracellular water potential and serious disturbance to the cytoplasm. In order to compensate for this imbalance, the relative contribution of water channels to flow across the root could thus vary. K. candel is a species that is native to intertial zone of tropical and subtropical coast and is well-adapted to salt conditions. The coordinated down-regulation of aquaporins in this plant may decrease membrane water permeability and thus increase the cellular water conserva- tion during periods of salt stress. The results reported here are consistent with the postulated roles for tonoplast water channels in regulating the hydraulic permeability of the vacuolar membranes and in adjusting the water homeostasis of the protoplasm under various physiological conditions. The identification of KCTIP1 as one of salt-responsive genes implies that intracellular osmotic equilibration is a part of salt-tolerant mechanisms in Mangroves.

There seems to be a contradiction among the symptoms of"non-thirst"and"thirst after oral use of the decoction"stated in original text 41 of Shang Han Lun(Treatise on Febrile Diseases)and the symptom of"probable thirst"stated in original text 40.In this article,the symptoms of thirst or non-thirst in the syndrome of Xiao Qinglong Decoction were expounded through the analysis of the basic theories of traditional Chinese medicine about body fluid metabolism and the pathogenic mechanism of thirst,and by synthesizing the relevant articles recorded in Jin Gui Yao Lve(Synopsis of the Golden Chamber)and the understanding of the syndrome of Xiao Qinglong Decoction by later generations of practitioners.After that,the following views are put forward:non-thirst symptom is the primary sympton of the syndrome of Xiao Qinglong Decoction,which results from the disease;thirst after oral use of the decoction is due to drug-induced thirst,which can be classified into the category of physiological thirst;probable thirst symptom is related with fluid consumption by febrile disease,indicating that the disease involves yangming.The analysis of the symptoms of thirst or non-thirst in the syndrome of Xiao Qinglong Decoction is helpful for evaluation of therapeutic efficacy,and can also be used as the indications of modified medications and differential diagnosis of the disease.The exploration will provide references for the clinical use of Xiao Qinglong Decoction and will be beneficial to improving the clinical efficacy of Xiao Qinglong Decoction.

OBJECTIVETo investigate the incidence and risk factors of sclerodermatous chronic graft-versus-host disease (ScGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODSThe clinical data of 259 patients undergoing allo-HSCT in Nanfang Hospital between January, 2012 and December, 2014 were analyzed.

RESULTSChronic GVHD following allo-HSCT occurred in 134 (51.7%) cases, among whom 22 patients showed sclerodermatous features at a median of 12.5 months (range 4-28 months) after the transplantation. The overall incidence of ScGVHD was 8.49% (22/259) in the recipients and 16.4% (22/134) in those with cGVHD. Univariate analysis showed that the conditioning regimen with total body irradiation (P=0.031), GVHD prophylaxis with MMF (P=0.046), presence of chronic GVHD (P=0.008), and donor lymphocyte infusion (P=0.001) were all closely associated with the occurrence of ScGVHD. Multivariate analysis identified chronic GVHD (RR=3.512, 95%CI: 1.235-9.987, P=0.018) and donor lymphocyte infusion (RR=5.217, 95%CI: 1.698-16.029, P=0.004) as the independent risk factors of ScGVHD.

CONCLUSIONScGVHD following allo-HSCT is not a common complication, and cGVHD and donor lymphocyte infusion are the independent risk factors for ScGVHD.

OBJECTIVETo explore the association between chromosomal damage induced by vinyl chloride monomer (VCM) and polymorphisms of xenobiotic metabolism genes and DNA repair genes.

METHODSCytokinesis-block micronucleus (CBMN) test was performed to detect chromosomal damage in peripheral lymphocytes of 402 VCM-exposed workers. Multiplex PCR was used to simultaneously amplify GSTM1 and GSTT1 genes, other genetic polymorphisms were performed using a PCR-RFLP technique.

RESULTSMultiple (adjusted) Poisson regression analysis showed that mean MN frequencies were significantly elevated for the intermediate (4000-40000 mg) and high (> 40000 mg) exposure groups as compared with the low exposure group (P = 0.003 and 0.03, respectively). For genetic polymorphisms, the exposed workers with CYP2E1 or XRCC1 Arg280His variance showed a higher CBMN frequency than their wild-type homozygous counterparts (P = 0.02); so did the workers with GSTP1 105Val/Val genotype or ALDH2 504Glu/Glu genotype than those with a combination of other genotypes (P = 0.01 and 0.003, respectively).

CONCLUSIONOur findings reveal that cumulative exposure dose of VCM and common genetic variants in genes, such as GSTP1, CYP2E1, ALDH2, XRCC1 Arg280His genotypes, are the major factors that modulate MN induction in VCM- exposed workers. Further study to investigate the relationship between individual characteristics and genetic susceptibility to VCM-caused chromosome damage is warranted, it is helpful for us to understand the mechanism of VCM metabolism, to find the biomarkers of susceptibility and to recognize the susceptible individuals in the primary prevention of VCM-caused damage.
