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.

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.

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.

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.

BACKGROUNDThe surgical treatment of intramedullary spinal cord tumor aims at complete removal and minimal postoperative deficit. This study was undertaken to evaluate the microsurgical features of intramedullary spinal cord tumors and the time for surgery and prognosis.

METHODSTwenty-one patients with intramedullary spinal cord tumor who had been treated at Nanfang Hospital, Guangzhou, China since 2000 were studied retrospectively. Fifteen patients were men and 6 women, aged 2 - 60 years (mean 29.28 years). Thirteen patients had the tumor in the cervical segments, 4 in medulla-cervical segments, 1 in cervicothoracic segment, and 3 in thoracic spine. All the patients underwent microsurgery for the tumor through posterior approaches by laminectomy. The tumor was exposed through dorsal myelotomy, then tumor plane was removed carefully from the entire rostrocaudal area. The dura was sutured routinely. In case of tumors occupying too many spinal segments, titanium strip was applied to reconstruct the vertebral plate and keep the spinal column stable. All the patients were subjected to MR imaging early after operation.

RESULTSComplete removal of the tumor was made in 15 patients, subtotal removal in 5, and partial resection in 1. Neurological recovery was related primarily to preoperative neurological conditions of the patients. Patients with minor neurological deficit showed stable sensory and motor function or minor loss in the early postoperative period, and neurological function tended to improve with time. But those with significant or long-standing deficit could hardly demonstrate any recovery. The dissection interface between the tumor and normal cord tissue was the most important factor influencing the extent of surgical removal.

CONCLUSIONSIntramedullary spinal cord tumor mostly take place in cervical segments, with glioma as the commonest type. Microsurgery is the major treatment of choice, by which tumor plane could be totally resected. Excellent microsurgical expertise and careful recognition of tumor plane are essential to removal of the tumor while retaining neurological functions. Titanium strip fixation is helpful to reconstruct vertebral stability. Preoperative neurological conditions of patients are directly related to their postoperative recovery. We underscore the importance of early diagnosis and radical microsurgical treatment of intramedullary spinal cord tumor.

OBJECTIVETo study the mechanism in masticatory muscle dysfunctional induced by hemimastication.

METHODSCa2+ contents were measured with atomic absorption spectrometry; calcinuerin were measured with colorimetric method; muscle fiber types were measured with adenosine-triphosphate (ATPase) staining.

RESULTS(1) Compared with the controls, Ca2+ contents in experimental group had the higher level except 8 weeks (P < 0.05). (2) The ratio of slow fiber in experimental group increased, higher than the match groups (P < 0.05). (3) With Ca2 contents rise, the activities of calcinuerin present a bell-like shape. (4) The ratio of slow-type fiber was positively correlated to the activities of calcinuerin (r = 0.876, P < 0.05).

CONCLUSIONThe signal way of muscle fiber growth and fiber transformation were activated by high concentration of calcium, then, muscle fiber transferred from fast to slow type. It may play an important role in the mechanism that hemimastication result in masticatory muscles dysfunction.

The alterations of taurine transport and the expression of taurine transporter (TAUT) mRNA in myocardium and aortic wall were investigated in spontaneously hypertensive rats (SHR) and Wistar-Kyoto (WKY) rats. It was demonstrated that plasma taurine concentration and taurine release from myocardium and aortic wall in SHR were higher than those in WKY rats, whereas taurine content, taurine uptake and TAUT mRNA in myocardium and aortic wall of SHR were lower than those of WKY rats. In SHR, the maximal velocity (V(max)) of taurine transportation in myocardium and aortic wall was lower by 24% (P<0.05) and 35% (P<0.05) than that in WKY, their michaelis constants (Km) values were higher by 16% (P<0.05) and 39% (P<0.05), respectively. The results suggest that there is dysfunction of taurine transport in myocardium and aortic wall in SHR, which may be partly resulted from the decrease of TAUT activity and affinity, and down-regulation of TAUT gene expression.
