Objective To investigate surgical opportunity and suitable treatment approach in nodular Hashimoto's disease.Methods An analysis was performed in 388 pathologically confirmed cases with nodular Hashimoto's disease and other thyroid-related diseases.All the cases were involved with surgical treatment due to thyroid nodules from June,1995 to Dec,2005.Results Among the above-mentioned cases,64 cases (16.5%) were Hashimoto's disease with the presence of thyroid cancer,190 (48.9%) nodular thyroid tumor,94 (24.2%) thyroid adenoma,7 (1.8%) hyperthyroidism,the rest (8.5%) simple Hashimoto's disease.Prior to 2000, among 106 cases of Hashimoto's disease there were 15 cases accompanied by thyroid cancer.Since 2001,282 cases of Hashimoto's disease were dealt surgically,49 of which had thyroid cancer.Compared to the period from 1995 to 2000,the complication of Hashimoto's disease and thyroid cancer has been sharply increasing during the recent five years (P

To investigate formation mechanism of secologanic acid sulfonates in sulfur-fumigated buds of Lonicera japonica, secologanic acid was enriched and purified from the sun-dried buds of L. japonica by various column chromatography on macroporus resin HPD-100, silica gel and ODS. The stimulation experiments of sulfur-fumigation process were carried out using secologanic acid reacted with SO2 in the aqueous solution. The reaction mechanism could be involved in the esterification or addition reaction. The present investigation provides substantial evidences for interpreting formation pathway of secologanic acid sulfonates in sulfur-fumigated buds of L. japonica.

OBJECTIVETo investigate the effects of the plasma containing Qianlongtong Capsule (QLT)-containing plasma on the expression of the Smad4 gene in prostate stromal cells in vitro and provide some experimental evidence for the treatment of benign prostatic hyperplasia (BPH) with Chinese medicinal compound.

METHODSFifteen cases of BPH were equally randomized to three groups to be treated with QLT at a high dose (6 capsules once), a medium dose (3 capsules once), and a low dose (1.5 capsules once), tid, for 7 days consecutively. QLT-containing plasma was collected from the patients. Prostate stromal cells were identified by immunofluorescence when they became monolayered and cultured in the QLT-containing plasma for 24 hours, followed by detection of the expression of the Smad4 gene by real-time quantitative PCR and that of the Smad4 protein by Western blot.

RESULTSAfter treatment with the QLT-containing plasma, the expression of the Smad4 gene in the stromal cells was significantly increased in a dose-dependent manner as compared with the blank control and no-QLT groups (P < 0.01). The expression of the Smad4 protein was also markedly elevated after treatment. The differences were statistically significant between the blank control and medium-dose groups (P < 0.01), low-dose and medium-dose groups (P < 0.05), and high-dose and the other groups (P < 0.01), but not between the blank control and low-dose groups (P > 0.05).

CONCLUSIONQLT-containing plasma could inhibit the proliferation and improve the apoptotic index of prostate stromal cells in vitro, which was related to the elevation of the mRNA and protein expressions of Smad4.

A fusion protein of glucagons-like peptide-1 and human serum albumin (GLP-1/HSA) was expressed and secreted into the fermentation broth with recombinant Pichia pastoris. The productivity of expressed GLP-1/HSA could reach 63.6mg/L in 10L fermentor. After concentrated with hollow-fiber ultrafiltration membrane, GLP-1/HSA was purified from fermentation broth by hydrophobic chromatography, negative ion exchange chromatography and gel filtration chromatography in turn. The HPLC analysis showed that the purified GLP-1/HSA had an overall purity of 95.8%. Furthermore, the analysis of in vivo activity indicated that GLP-1/HSA had the bioactivity of native GLP-1, and could significantly reduce blood glucose level 4h after intraperitoneal administration. It was concluded that a great deal of GLP-1/HSA with higher purity could be harvested by Pichia pastoris expression system and the established purification methods. Preliminary studies show a new potential for developing the long-acting GLP-1 analogs for clinical applications.

Objective To analyze if there are membrane estrogen receptors(ER)in endometrial carcinoma and if there is some relationship between membrane ER and nuclear ER.Methods The cell membrane and total cell ER?and ER?expressions of high and moderate differentiation endometrial carcinoma cells(Ishikawa and HEC-1A cells)were analyzed.Intermittent immunofluorescence dyeing and fluorescent microscopy were carried out with the ceils treated with polyformaldehyde and Triton X-100. Intermittent immunofluorescence dyeing and flow cytometry were carried out with the live cells and the cells treated with Triton X-100 respectively.Results There were fluorescences on the membrane of the Ishikawa and HEC-1A cells which were treated with polyformaldehyde.When the cells were treated with Triton X- 100,the fluorescences were also seen inside the cells.The fluorescence intensity of ER?and ER?in Ishikawa cell membrane(1.09?0.21,1.27?0.33)was stronger than the control,but there were no significant differences(P＞0.05).When treated with Triton X-100,the total cell fluorescence intensity of ER?and ER?in Ishikawa cell(4.21?0.34,4.69?1.96)was stronger than the membrane(P＜0.05). The ER?and ER?fluorescence intensity of HEC-1A cell membrane(1.58?0.13,1.49?0.04)were stronger than the control(P＜0.05).The fluorescence intensity of ER?and ER?of the HEC-1A cell (2.34?0.33,2.52?0.15)was stronger than the membrane also(P＜0.05).The membrane ER?fluorescence intensity of Ishikawa was lower than HEC-1A(P=0.028).But the total cell ER?fluorescence intensity of Ishikawa was higher than HEC-1A(P=0.002).Conclusions There are membrane ER on endometrial carcinoma cells Ishikawa and HEC-1A.The membrane ER must have some similarity to the nuclear receptor.There is no direct correlation between the quantity of the membrane ER and nuclear ER.

Objective To observe the long term effects of arthroscopic knee debridement and reconstructing operation for treating osteoarthritis in patients with Kaschin-Beck disease. Methods Thirty-one cases of patients with Kaschin-Beck disease were followed for 6 years after operation of articular clearing by arthroscope. Index of pain, symptoms of self-evaluation, range of motion, walking distance, standing test by affected leg when bending at 30° or 60° were recorded and compared with the preoperative results. Results Twenty-four cases were followed up for 6 years. Six years after operation the pain index(3.38 ± 2.87) was dramatically decreased compared to that before operation (6.88 ± 1.45, t = 5.30, P ＜ 0.05). Patients symptoms markedly improved by subjective self-evaluation was 70.83% (17/24), the effective rate was 100% (24/24). The number of cases that could stand up when leg bending at 30° or 60° were 21,18 cases, respectively, compared with that of preoperative of 14, 11 cases, respectively, the difference was statistically significant(x2 = 5.17,4.27, all P ＜ 0.05). Six years after operation the walking distance(3 cases ＜ 1 km, 11 cases 1 - 5 km and 10 cases ＞ 5 km) were greatly improved compared to the results before operation (12 cases ＜ 1 km, 9 cases 1 - 5 km and 3 cases ＞ 5 km, U = 2.88, P ＜0.05). Six years after operation the knee activity[(132.25 ± 14.52)°] remained at the same level, compared with that of preoperative [(131 .58 ± 14.68) °], the difference was not statistically significant (t = 0.16, P ＞ 0.05) .Conclusions The method of arthroscopic joint debridement to cure Kaschin-Beck disease knee osteoarthritis can significantly reduce pain, improve function and walking distance, with more stable long-term satisfactory outcome.

Objective To observe the expression of vascular endothelial growth factor(VEGF) mRNA and protein in fluoride(F~-) treated fibroblast(FB) of mice in planar(2D) and FBs populated collagen lattice(3D) culture systems and to further explore the effects of VEGF on the osteogenic action of FB. Methods FB were divided into 0 (control group), 0.0001,0.0010,0.1000,1.0000,10.0000 and 20.0000 mg/L groups(F~-). The levels of VEGF mRNA and protein at 48 h were measured by using RT-PCR, ELISA and immunohistochemistry (IHC) methods. Results The expression of VEGF mRNA increased obviously in group of 0.1000 mg/L(1.08 ± 0.09) in 3D FB compared with the control group(0.93 ± 0.02, all P < 0.05). Fluoride increased the content of VEGF protein obviously in groups of 0.1000,1.0000,10.0000 mg/L(0.19 ± 0.02, 0.26 ± 0.01 and 0.32 ± 0.01 ), higher than that in 2D FB culture supematant in the control group(0.14 ± 0.01, all P < 0.05) ; and in groups of 0.1000, 1.0000 rag/L(0.59 ± 0.06 and 0.52 ± 0.03) it was higher than that in 3D FB culture supematant in the control group(0.37 ± 0.05, all P< 0.01 ). The IHC results showed that the VEGF positive staining cells increased significantly in group of 0.001 mg/L (0.45 ± 0.05) in 2D FB when it was compared with control group(0.36 ± 0.03, P< 0.05); and in groups of 0.0010, 0.1000, 1.0000 rag/L(0.62 ± 0.04,0.70 ± 0.06 and 0.65 ± 0.07) are it was higher than that in 3D FB control group (0.44 ± 0.04, P < 0.05 or < 0.01 ). Conclusions The higher expression of VEGF mRNA and protein in 2D and 3D FB induced by fluoride may play an important role in stimulating the osteogenesis ability in FB.
