OBJECTIVETo explore the effects of electroacupuncture on exercise-induced immunosuppression in rats and its mechanism.

METHODSSports immunosuppressive model was established successfully by the rats were conducted high intensity swimming training 150 min/day, 6 days/wk for 8 weeks in this study. Forty-three SD rats were randomly divided into a control group (group A, n = 10), a high intensity swimming training group (group B, n = 17), and a high intensity plus electroacupuncture group (group C, n = 16). Group A did not receive any intervention. Group B was conducted 150 min/day, 6 days/wk swimming training for 8 weeks. Group C was treated with electroacupuncture at "Baihui" (GV 20), "Guanyuan" (CV 4) and "Zusanli" (ST 36) after every exercise-time from the second week, once each day for 7 weeks. The changes of the rats' weight, gamma-interferon (gamma-IFN), interleukin-2 (IL-2), solubility IL-2 receptor (SIL-2R) and nature killer cell (NKC) were detected.

RESULTS(1) Compared with group A, gamma-IFN and IL-2 in group B were significantly decreased (P < 0.01, P < 0.05), and NKC in group C was significantly increased (P < 0.01). Meanwhile, gamma-IFN and NKC in group C were both significantly higher than that in group B (P < 0.05, P < 0.01). (2) Compared with group A, the weight of the rats in group B and group C were significantly decreased (both P < 0.01), but SIL-2R in group B was significantly increased (P < 0.05). The weight of the rats in group C was significantly higher than that in group B (P < 0.05) and SIL-2R in group C was significantly lower than that in group B (P < 0.01).

CONCLUSIONLasting gravis exercise stress does decrease the immune function in rats and is even inhibited significantly, but electroacupuncture can up-regulate the exercise-induced immunosuppression.

Objective To investigate clinical characteristics of relapsing polychondritis(RP)and to improve early recognition for it.Methods Clinical and laboratory data of 56 patients with RP were analyzed retrospectively.Results Ratio of number of male patients to female ones was 1.2.Age at onset was(46?11)years(ranging from 27 to 71)and average interval between onset and diagnosis was(21? 35)months,(8?6),(16?31)and(29?37)months for patients initial onset with auricle,respiratory tract and joints involved,respectively.Site involved included airway in 40 patients(71.4%),auricle in 32 (57.1%),joints in 32(57.1%),eyes in 27(48.2%),nasal chondritis in 25(44.6%)and inner ear in 13(23.2%).At initial stage of the course,17 patients were misdiagnosed as respiratory infection (30.4%),nine as perichondritis(16.1%),six as pulmonary tuberculosis(10.7%),five as rheumatoid arthritis(8.9%).Seven of 40 patients with airway involvement received metallic stents for their tracheobronchial stenosis.Four patients whose condition never improved after regular therapy all had respiratory involvement.Conclusions Patients of RP with initial onset at non-auricle,non-nasal sites tended to be misdiagnosed.Prevalence of airway involvement was not so low with a poor prognosis in patients of RP.

The dynamic changes of germination percentage, germination potential, thousand-seed weight, antioxidase activity in Desmodium styracifolium seeds with different storage time were tested, and electrical conductivity, contents of soluble sugar, soluble protein, starch in seed leach liquor were also determined in order to reveal the mechanism of seed deterioration. The results as the following. (1) The germination percentage, germination potential and thousand-seed weight of D. styracifolium seeds declined, while the seed coat color darkened with the extension of storage time. (2) The activities of superoxide dismutase (SOD) and peroxidase (POD) decreased with the prolongation of storage period. The SOD activity declined fastest in 1,095-1,185 d of storage, while the POD activity declined significantly in 365-395 d of storage. (3) The electrical conductivity and the contents of soluble sugar, starch in seed leach liquor increased, while the content of soluble protein declined with the extension of storage time. (4) Correlation analysis indicated that the germination percentage, germination potential and thousand-seed weight of D. styracifolium seeds have a significantly positive correlation with SOD and POD activity, while have a significantly negative correlation with the electrical conductivity, contents of soluble sugar and starch. It can be concluded that during the storage of D. styracifolium seeds, physiological and biochemical changes including decrease in antioxidase activity, rise in electrical conductivity, degradation effluent of soluble sugar and starch, degradation of soluble protein were the main factors leading to the seed deterioration.

OBJECTIVETo explore the growth characteristics of Curcuma longa, and provide basis for standardized cultivation.

METHODPlant samples were collected and investigated periodically.

RESULTAccording to the growth of different parts and the characteristics of dry substance accumulation of C. longa, the development of C. longa could be divided into five stages: emergence of seedlings, seedling, leaf, root tuber expansion, and dry substance accumulation of root tuber. In terms of number, leaf of C. longa increases gradually from one at first to eight at the final stage. Leaf size increases at a very low speed at the stage of seedling. However, leaves expands their sizes at a much higher speed at the stage of leaf. The dry substance in different parts accumulates increasingly with the development of C. longa dry substance mainly accumulates in leaves at the stage of leaf, and in rhizome at the stage of root tuber expansion. At the final stage, it mainly accumulates in root tuber.

CONCLUSIONCultivation technologies of C. longa and the relevant management methods could be established according to the growth of different parts of C. longa and the characteristics of dry substance accumulation in different stages.

The essence of endogenous turbidity in Chinese medicine (CM) is different from cream, fat, phlegm, retention, damp, toxicity, and stasis. Along with the development of modern scientific technologies and biology, researches on the essence of endogenous turbidity should keep pace with the time. Its material bases should be defined and new connotation endowed at the microscopic level. The essence of turbidity lies in abnormal functions of zang-fu organs. Sugar, fat, protein, and other nutrient substances cannot be properly decomposed, but into semi-finished products or intermediate metabolites. They are inactive and cannot participate in normal material syntheses and decomposition. They cannot be transformed to energy metabolism, but also cannot be synthesized as executive functioning of active proteins. If they cannot be degraded by autophagy-lysosome or ubiquitin-prosome into glucose, fatty acids, amino acids, and other basic nutrients to be used again, they will accumulate inside the human body and become endogenous turbidity. Therefore, endogenous turbidity is different from final metabolites such as urea, carbon dioxide, etc., which can transform vital qi. How to improve the function of zang-fu organs, enhance its degradation by autophagy-lysosome or ubiquitin-prosome is of great significance in normal operating of zang-fu organs and preventing the emergence and progress of related diseases.

OBJECTIVETo figure out the differences of the morphological characteristics of mandibular symphysis between Class II and Class III adult skeletal malocclusions with different abnormal vertical skeletal patterns.

METHODS109 Chinese female adults of skeletal Class II and Class III were chosen and divided into four groups according to vertical and sagittal skeletal pattern: Class II--vertical-growth-pattern group (n=30), Class III--vertical-growth-pattern group (n=25), Class II--horizontal-growth-pattern group (n=29), Class III--horizontal-growth-pattern (n=25). Lateral cephalograms were taken. The symphyseal widths and heights, along with lower incisor positions were evaluated. Observation and statistics analysis were done to clarify the morphological characteristics of the symphyseal region of different skeletal patterns.

RESULTSThere were morphological differences of symphyseal region between Class II and Class III skeletal malocclusions, but not significant in width and total height. With a vertical-growth-pattern, Class II malocclusions had higher alveolus than Class III, but smaller chin prominence and lower basal bone (P < 0.01). With a horizontal-growth-pattern, Class II malocclusions had higher alveolus (P < 0.05) and larger alveolar top width (P < 0.001). With a same sagittal skeletal pattern, vertical-growth-pattern group had thinner but higher symphyseal region and bigger chin prominence (P < 0.001 in Class II while P < 0.05 in Class III). Besides, a vertical-growth-pattern malocclusion was prone to have a cucurbit-morph chin, of which Id width was larger than basal width (P < 0.01).

CONCLUSIONThere are morphological differences in symphyseal region between Class II and Class III skeletal malocclusions with different abnormal vertical skeletal patterns. The influence of abnormal vertical skeletal pattern to symphyseal morphological characteristics is greater than that of abnormal sagittal skeletal pattern. There is a risk of orthodontic movement of low incisors in vertical-growth-pattern skeletal malocclusion.

OBJECTIVETo observe the dynamic change in expression of protease-activated receptor 2 (PAR2) during onset and progression of liver fibrosis by using a rat model.

METHODSA cholestatic liver fibrosis model was established in Sprague-Dawley rats (aged 8-9 weeks, body weight 350 - 400 g) by bile duct ligation surgery. Rats receiving a sham operation and unoperated rats served as the negative and normal control groups, respectively. At baseline (pre-surgery) and post-surgery weeks 2, 4, 6, and 8, five rats from each group were sacrificed for whole liver resection. The protein and mRNA expressions of PAR2 and collagen I/III were detected by western blotting and RT-PCR, respectively. Between-group differences were assessed by analysis of variance testing.

RESULTSAt post-surgery week 2, the liver fibrosis group showed higher expression of PAR2 mRNA and protein than either control group. The expression levels of PAR2 continued to rise over time in the liver fibrosis group (peaking at week 8), and were significantly higher than those detected in the control groups (weeks 4-6: P less than 0.05; week 8, P less than 0.05). A similar trend was observed for the expression of collagen I/III.

CONCLUSIONDynamic expression of PAR2 observed in a cholestatic liver fibrosis rat model may indicate a role for this factor in the formation of liver fibrosis.

OBJECTIVETo evaluate autogenous vein grafts and inside-out vein grafts as conduits for the defects repair in the rabbit facial nerves.

METHODSThe 10 mm segments of buccal division of facial nerve were transected for 48 rabbits in this study. Then the gaps were immediately repaired by autogenous vein grafts or inside-out vein grafts in different groups. All the animals underwent the whisker movement test and electrophysiologic test during the following 16 weeks at different time points postoperatively. Subsequently, the histological examination was performed to observe the facial nerve regeneration morphologically.

RESULTSAt 8 weeks after operation, the facial nerve regeneration has significant difference between the experimental group and the control group in electrophysiologic test and histological observation. However, at the end of this study, 16 weeks after operation, there was no significant difference between inside-out vein grafts and standard vein grafts in enhancing peripheral nerve regeneration.

CONCLUSIONThis study suggest that both kinds of vein grafts play positive roles in facial nerve regeneration after being repaired immediately, but the autogenous inside-out vein grafts might accelerate and facilitate axonal regeneration as compared with control.
