Objective:To observe the clinical effect of tuina plus Baixiao moxibustion in the treatment of temporomandibular joint dysfunction syndrome (TJDS). Methods: A total of 70 TJDS patients who met the inclusion criteria were randomized into an observation group and a control group by flipping a coin, with 35 cases in each group. Patients in the observation group were treated with tuina plus Baixiao moxibustion, while patients in the control group received oral intake of diclofenac potassium (75 mg/pill), 1 pill after every dinner. Both tuina and Baixiao moxibustion were done once a day during treatment. The therapeutic evaluation was evaluated after 10 treatments in both groups. The maximum mouth opening distance and visual analog scale (VAS) were observed before and after treatment, and the therapeutic efficacy was also compared. Results: After treatment, the maximum mouth opening distance and VAS improved in both groups (all P＜0.05); both items in the observation group were superior to those in the control group (both P＜00.05). The total effective rate was 91.4% in the observation group, versus 74.3% in the control group, and the between-group comparison of the total effective rate showed statistical significance (P＜0.05). Conclusion: Tuina plus Baixiao moxibustion can effectively improve TJDS patient’s temporomandibular joint function and alleviate pain, with better efficacy than oral intake of diclofenac potassium.

Objective To investigate the effects of different concentrations of sodium fluoride on the morphologic characteristics of primarily cultured thyroid cells of SD rats and in order to obtain important proof for approaehing the mechani8m of thyroid gland damage caused by fluoride.Methods Thyroid cells of SD rat were primarily culture for 96 hours,and cell density was adjusted to 5.0×108/L Cell suspension with 5 ml Wills seeded into 6 weII plates,after 12 hours,0(contr01),10.100,1000 μmol/L of sodium fluoride was added into the well, witll each well representing different level of treatment group.Finally the cultured thyroid cells were collected for morph010gic study.Results Under microscope,the transparency of the control thyroid cells Was good,and cells gathered in cluster and adhered to wall.But a lot of cells treated with fluoride suspended,and lost their transparency-under scaning delectron microscope,the control calls showed integrated membrane and tightness to each other,as well as clear boundary between cells normal proliferation.While the thyroid cells treated with 10,100 μmol/L sodium fluoride 0bviouslv shrinked and deformed,and the cells treated with 1000 μmol/L of sodium fluoride were broken-Conclusions nuoride can affect the growth and development of thyroid cell and damage the structure and morphology.Sodium fluoride affects the morphologie characteristics of thyroid cells in a dose-response manner.

Objective To determine the therapeutic effect of recombined rat insulin-like growth factory 1 gene and transforming growth factor beta-1(TGF-?_1)gene on anterior cruciate ligament transection(ACLT)- induced osteoarthritis-like changes in NZW rabbit knee joints.Methods Eighteen NZW rabbits were divided into 3 groups randomly after osteoanhritis was established by ACLT and another six rabbits were used as normal control group(group 1).Chondrocytes which had been transfected with IGF-1 gene,co-transfected with TGF-?_1 and IGF-1 gene(group 3,4)were injected into the rabbits knee joints.Experimental control group(group 2)only had ACLT bul was not transfected.After 4,8 weeks,rabbits were sacrificed and their joints were evaluated by morphological grades,histological examination,in situ hybridization examination,immunohistochemistry exami- nation,and transmission electron microscopy examination(TEM).Results The morphological grades showed that the normal control group had a very significant difference with the experimental control group(P

Objective To determine the effect of iron deficiency on hemoglobin A2(HbA2) expression in patients with β-thalassemia.Methods The participants were recruited from the out-patient clinics of the Pediatrics Department and Obstetrics Department of Affiliated Hospital of Guilin Medical College and from some β-thalassemia major families.Blood samples from the participants were used for blood smear tests and hemoglobin electrophoresis and to analyze serum ferritin (SF),3 alpha-globin gene deletions,and 17 beta-globin point mutations.Results Of the 408 individuals,304 were assigned to group A (normal controls),26 to group B (iron deficiency),56 to group C (β-thalassemia),and 22 to group D (β-thalassemia combined with iron deficiency). The results for the comparison of the mean HbA2 values among pairs of groups were as follows: group A vs group B,q=5.074 7,P<0.05; group A vs group C,q=37.650 8,P<0.05; group A vs group D,q=16.043 0,P<0.05;group C vs group D,q=7.682 9,P<0.05; Group B vs group D,q=15.806 6,P<0.05. There were no significant correlation between SF and HbA2 in all 4 groups.Conclusions Iron deficiency decreased the HbA2 level in both controls and individuals with β-thalassemia. HbA2 levels decreased significantly in individuals with both β-thalassemia and iron deficiency as compared with β-thalassemia group alone. However,they remained significantly higher than both the control and iron-deficient groups. Therefore,the elevation of HbA2 could be used to diagnose β-thalassemia reliably even in the presence of iron deficiency.

Objective To investigate the imaging features of perivascular epithelioid cell tumor of liver (PEComa),and to improve the diagnostic level of the disease. Methods A retrospective analysis of imaging manifestations was performed on 11 cases of hepatic hemangioma confirmed by surgery and pathology. All patients underwent CT and MRI examination before PET/CT examination ,then received operation. Results Eleven cases were solitary hepatic lesions ,10 of which were located in the right lobe of the liver ,and 1 in the left. The lesions were round or quasi-circular and the diameter ranged from about 13.5cm to about 1.8 cm,with an average of 5.7 cm. CT plain scanning showed that the liver was slightly lower density ,with clear boundary. The smaller lesions were homogeneous density,while the larger ones were not,and the lower density area was visible. Enhancement of peripheral lesions in the arterial phase was enhanced. The lesions in the portal vein were not uniformly enhanced , and visible separation was found in large lesions. In the delay phase ,the lesions were significantly decreased or slightly lower. MRI plain scan showed the lesion T1WI showed moderate signal or slightly low signal ,and large lesion signal was not uniform,and T2WI lesions showed slightly high signal while DWI lesions high signal and the enhanced features were similar to those of CT. PET/CT examination showed that visible radioactive uptake of abnormal concentration or uneven concentration were found in lesions with diameter larger than 3.0 cm,and the maximum SUV value ranged from 12.2 to 3.6,with an average value of 5.7. Lesions with diameter less than 3.0 cm showed a slight concentration of radioactive uptake and the highest SUV value was 4.7,with an average value of 2.9. The only 11.8 cm lesion showed no significant radioactivity ,which was as the same as that of normal liver tissue. Delayed PET/CT imaging(1 hour)showed that SUV values of all lesions were decreased in varying degrees. Conclusion PET/CT imaging of perivascular epithelioid cell tumor of liver has its characteristics. The combina-tion of PET/CT imaging and routine imaging examination will benefit the improvement of diagnosis level obviously.

As an immediate-early protein of herpes simplex virus, infected-cell polypeptide 0 (ICP0) exhibits complicated interactions with host cells, and its regulatory function on gene expression is of great importance. Since the ICP0 encoding sequence contains many rare codons which are absent in E.coli, and ICP0 is highly unstable in prokaryotic cells, expression of entire ICP0 in prokaryotic cells has never been reported. In order to further investigate the function of ICP0, a recombinant plasmid was constructed by subcloning a cDNA fragment encoding an amino-terminal of 105 residues of the ICP0 protein into pGEX-5x-1 vector. The resulting GST-105 fusion antigen peptide was expressed with high efficiency in E.coli. Antibodies prepared after the immunization of mice with purified fusion protein can recognize not only the denatured ICP0 protein, but also the native ICP0 protein with normal biological conformation.

Little is known about the non-structural protein 6(NSP6)of rotavirus.This report describes expression of the NSP6 of a group A human rotavirus strain TB-Chen in bacteria,and its immunological properties and cellular distribution.The results showed that the recombinant NSP6(rNSP6)was expressed in high efficiency without any other proteins fused(possesses about 34.2% of total bacterial proteins).rNSP6 elicited mono-specific antibodies in immunized guinea pigs and the antibodies could react with the rNSP6 itself and the viral NSP6 proteins synthesized in SA11-or Wa-infected MA104 cells in Western blot and immunofluorescence assay.The NSP6 distributed evenly in the cytoplasm mainly around the nucleus of virus-infected cells,no viroplasm-like gathering observed;The top amount of NSP6 synthesized in SA11-infected cells or Wa-infected cells could be detected at 12h after infection.This is the first report about the high expression of entire NSP6(without any other proteins fused)in prokaryotic expression system and detection of NSP6 synthesis in virus infected cells by immunofluorescence assay.The results are important to understand the structure,biological properties and further application of the NSP6.
