Objective To investigate the curative effect of endoscopic thyroidectomy via breast areola approach.Methods The clinical data of 28 cases of endoscopic thyroidectomy via breast areola approach were retrospectively summarized.Results The mean diameter ofthe tumor Was 2.9(1.7～4.2)cm.The mean operative time Was 128(95～165) min.Pathologic data:adenoma in 15 cases,nodular goitar in 12 csses,papillary carcinoma indicated intraoperatively by frozen section in 1 case.One case occurred temporary hoarseness.No intraoperative and postoperative hemorrhea and convulsion after operation.Minor pain and discomfort in anterior chest continued for 7～19d in 18 cases,all without taking painkillers,satisfaction rate of beauty was 90 percent.Condusions Endoscopic thyroidectomy via breast areola approach is safe and feasible for patients with thyroid diseases,and has excellent cosmetic results.

Serum cytokine concentrations were determined in patients with Graves'disease(GD)before and after treatment of thiamazole.Serum soluble interleukin-2 receptor(sIL-2R)level was markedly raised before treatment as compared with normal subjects and returned to normal after 3 month therapy.Serum IL-8 level was lowered in GD patients and showed no change after 3 month therapy.No relationship between IL-8 and other markers was found.Serum IL-1?,IL-6 and TNF-?levels in GD patients showed no difference with those in normal controls.

The study was aimed to observe the effect of recombinant human granulocyte-colony stimulating factors (rhG-CSF) in low dose on peripheral blood stem cell (PBSC) mobilization in unrelated healthy normal donors. G-CSF was administered at 5 microg/(kg x d) subcutaneously for successive 5 or 6 days to 56 unrelated donors. Stem cells were harvested on the fourth and fifth days or on the fifth and sixth days. The numbers of mononuclear cells (MNC), CD34(+) cells and Hb, Plt, and CD3(+), CD4(+), CD8(+) and CD20(+) cells were determined during the mobilization. The results showed that most common adverse events were bone pain (17.9%, 10/56), agrypnia (8.9%, 5/56) and lassitude (4.5%, 3/56) during rhG-CSF mobilization, but all donors were suffered less than grade II according to the WHO criteria, and did not need to stop the mobilization and not need to give special treatment. In harvest on day 4 - 5 and 5 - 6, MNC count was (5.95 +/- 1.52) x 10(8)/kg and (7.19 +/- 2.12) x 10(8)/kg; CD34(+) cells count was (3.03 +/- 1.09) x 10(6)/kg and (7.92 +/- 2.50) x 10(6)/kg. There were no significant differences in hemoglobin level and platelet count, the percentage of CD3(+) cells, CD4(+) cells, CD8(+) cells and CD20(+) cells between pre-mobilization and post-mobilization of rhG-CSF. It is concluded that the low dose of rhG-CSF 5 microg/(kg x d) for peripheral blood stem cell mobilization in unrelated healthy normal donors is safe and effective.

OBJECTIVETo study on growth characteristics of Curcuma wenyujin, and provide theoretical basis for the development of high-quality and high-yield medical material.

METHODThe morphological change of the plant was observed periodically, the content of volatile oil and dry matter in leaves, rhizome, root tuber was determine.

RESULTThe growth of C. wenyujin could be divided into 5 stages, i. e. seed germination, seedling, leaf growth, rhizome expansion, accumulation of dry matter, respectively. Before the stage of rhizome expansion, over 70% dry matter was accumulated in the aerial part of the plant, and during the stage of leaf growth, the maximum increase rate of dry matter in aerial part was 3.90 g/p/d. During the stage of rhizome expansion, the ratio of dry matter of rhizome increased quickly and reached above 33% , and the increase rate of dry matter of rhizome rise up to 3.83 g/p/d, in the end of the stage, the content of volatile oil in the rhizome also rose up to 1.20 mL x 100 g(-1).

CONCLUSIONDuring the whole growth stage, there are two growth centers, when the two curves of dry matter increase of aerial part and rhizome intersect, it is regarded as a signal that the growth transformed form the aerial part to rhizome. When the rate of dry matter from rhizome rise, the content of volatile oil in rhizome rises quickly with the increase of dry matter in rhizome. The optimal harvest time is in mid-December.

OBJECTIVETo compare balance ability between elderly individuals who practiced Tai-Chi-Chuan (TCC) for average 9.64 years and elderly individuals who did not practice TCC and its relationship with lower extremity muscle strength and ankle proprioception.

METHODSTwenty-five elderly volunteers were divided into two groups according to their TCC practcing experience. Sixteen were TCC group and the other nine were control population. Subjects completed a static balance test and ankle proprioception test using a custom-designed evaluation system, and concentric and eccentric knee extensor and flexor muscle strength tests. Subjects stood on the plate form to measure the proprioception in functional standing position which was differed from the previous studies. Multiple linear regressions were also used to predict the important factor affecting balance.

RESULTSTCC group performed better than the control group in balance, proprioception, and muscle strength of lower extremity. The proprioception was the most important factor related to balance ability and it can be accounted for explaining 44% of variance in medial-lateral sway direction, and 53% of variance in antero-posterior sway direction. The proprioception may be a more important factor which affecting the balance ability.

CONCLUSIONTCC training is recommended to the elders; as it can improve balance ability through better proprioception.

OBJECTIVETo investigate the value of in vivo proton magnetic resonance spectroscopy (MRS) in the assessment of hepatocellular carcinoma (HCC) and monitor its metabolic change shortly after transcatheter arterial chemoembolization (TACE).

METHODSIn this prospective study, 28 consecutive patients with large HCC (> or = 3 cm in diameter) confirmed by fine needle aspiration biopsy were recruited. The 1H MRS of all hepatic lesions and some uninvolved liver parenchyma were performed with 1. 5T whole body MR scanner. Among them, 15 cases were evaluated again about one week after TACE. The main metabolites such as choline and lipid before and after interventional therapy were measured to assess the early response of the tumor.

RESULTSThe technical success rate of 1H MRS in liver was high (33/41, 80%), closely related to breath motion, location of lesion, and size of voxel. In spectra, the choline compound peak of HCC elevated compared with uninvolved liver parenchyma. After TACE, both the amplitude and the area of choline resonance peak significantly descended (choline-to-lipid ratios from 0.352 +/- 0.080 to 0.167 +/- 0.030, P = 0.026; from 0.205 +/- 0.060 to 0.070 +/-0.020, P = 0.042, respectively); yet lipid resonance peak ascended.

CONCLUSIONSIn vivo 1H MRS is technically feasible for the evaluation of large focal hepatic lesions, however, the reproducibility and stability are not as good as routine MR scan. 1H MRS can monitor the early stage metabolic changes of HCC after TACE but limitation like quantification still exists.

OBJECTIVETo objectively assess the effect of Qiming Granule in the treatment of diabetic retinopathy (DR) by fluorescence fundus angiography (FFA).

METHODSIn a multi-center, randomized, parallel controlled clinical trial, patients with DR were randomly assigned to the control group (calcium dobesilate capsule) and the test group (Qiming Granule). Changes in the retinal blood circulation time were recorded by FFA after 3 months of medication.

RESULTSSignificant reduction was observed in the retinal arterio-venous circulation time (AVCT) in both groups (P<0.01), the value was 7.635+/-3.149 s before treatment and 5.165 +/-3.382 s after treatment in the treated group, and 7.737+/-3.413 s and 5.313+/-3.472 s in the control group respectively. Qiming Granule also reduced the arm-to-retinal circulation time (ARCT, P<0.05). The value was 17.867+/-3.872 s before treatment and 15.643+/-4.648 s after treatment in the treated group, and 17.217+/-3.833 s and 16.312+/-3.613 s in the control group (P>0.05) respectively. The ARCT in the tested group was reduced, with a statistically significant difference post-medication (P<0.01).

CONCLUSIONAs a Chinese medicine complex prescription, Qiming Granule may alleviate retinal hypoxia and ischemia by increasing retinal blood flow and improving the blood circulation.

Objective:To construct HIV-1 pseudovirus containing enhanced green fluorescent protein ( EGFP ) gene. To understand the interaction between the virus and the cells. Methods: HIV-1 pseudovirus containing EGFP gene was constructed by lentiviral packaging systems, and its EGFP gene was amplified using RT-PCR. The level of genomic integration and transcription of HIV-1 pseudovirus containing EGFP gene were detected on iDCs infected with HIV-1 pseudovirus. At the same time, research on expression of the EGFP gene in iDCs infected with HIV-1 pseudovirus was performed. Results:The EGFP gene of HIV-1 pseudovirus was detected through RT-PCR. The EGFP gene was identified in iDCs infected with HIV-1 pseudovirus through PCR and RT-PCR. The EGFP was observed in iDCs infected with HIV-1 pseudovirus under fluorescence microscopy. Conclusion: HIV-1 pseudovirus containing EGFP gene has been successfully produced. The HIV-1 pseudovirus that we constructed can infect iDCs,then its RNA can integrate into the genome of iDCs in the way of reverse transcription,and the EGFP gene could express in the iDCs after infected with HIV-1 pseudovirus.

Objective　To explore the characteristics of the changes of several metabolic and biochemical indices in dogs with both hindlimbs injured by kinetic weapon. Methods　12 animals were divided into 4 groups (Group Ⅰ, injured by regular weapon; Group Ⅱ,Ⅲ,Ⅳ injured by imitative kinetic weapons with different energy respectively). Levels of plasma Na+,Ca2+,K+ glucose, AMY, LDH, CK and serum T3,insulin,TSH were determined before and after injured. Results　①Local wounding conditions and distant organs' injuries in group Ⅱ,Ⅲ, and Ⅳ were more serious than those in group Ⅰ. ②Levels of plasma glucose in group Ⅱ,Ⅲ and Ⅳ were inereased significantly after injury than before(P<0.05), but not in group Ⅰ. Levels of Na+,Ca2+,K+,AMY,LDH in 4 groups had similar changes after injury while levels of CK in group Ⅱ,Ⅲ and Ⅳ were inereased significantly than that in group Ⅰ (P<0.05). ③After injury, levels of T3 in serum of all animals showed a decreased tendency and that of insulin decreased more significantly (P<0.05). There was no difference between every two groups. Levels of TSH in group Ⅱ,Ⅲ and Ⅳ were increased significantly after injured than before (P<0.05), but not in group Ⅰ. Conclusion　Not only local severe injury but also more serious injury in distant organs and more obvious changes of metabolic and biochemical indices can be induced by kinetic weapons than regular weapons.

Objective To summarize the clinical data in preventing HBV recurrence after liver transplantation and explore a optimal individual protocol in prophylaxis of HBV recurrence. Methods We retrospected outcomes in 195 recipients who underwent a liver transplantation for HBV-related liver disease between June 2004 and July 2008. According to the anti-virus protocol these recipients are divided into two groups as following: group A received a protocol of combination treatment of lamivudine with HBIG, and group B with combination treatment of adefovir with HBIG. With mean follow-up of 23.7 months, HBV recurrent rate was observed in overall and each group separately. Results A total of 195 liver transplant recipients were identified that met the study criteria. At the sixth and eleventh month after operation, HBV recurrence appeared in 2 recipients, each in two groups, which were due to LAM cessation and HBV mutation respectively. Recurrent rate was 0.6% in group A, 3.7% in group B and 1% in total. There was no significant difference in HBV recurrent rate between group A and B. Conclusion Lamivudine combined with HBIg should be considered as a reliable method in preventing HBV recurrence after liver transplantation. Better outcomes can be achieved by individual anti-virus protocol and HBIg administration according to HBV stares in recipient.
