ObjectiveTo investigate the corelation between fibrinogen in pleural effusion and pleural adhesion in tuberculosis exudative pleurisy.Methods234 cases of primary tuberculosis pleurisy were divided into 3 groups (A、B、C) according to their level of fibrinogen in pleural effusion from low to high. The incidence rates of pleural adhesion were assessed during the course of treatment and after treatment.ResultsThe incidence rate of pleural adhesion in the course of treatment were as those: group A 10.5%, group B 32.3%, group C 54.5%. After treatment, it was as those: group A 10.5%, group B 16.9%, group C 42.4%. Whenever, there was significant difference between group C and group A or B (P<0.05).ConclusionThe level of fibrinogen in pleural effusion may be associated with pleural adhesion, which hinder the recovery of patients.

OBJECTIVETo observe the impacts of acupoint catgut embedding therapy and acupuncture-moxibustion therapy on the long-term efficacy and patient's life quality in the treatment of allergic rhinitis.

METHODSSixty-nine patients were randomized into the combined acupuncture-moxibustion and acupoint catgut embedding therapy group (combined therapy group, 36 cases) and an acupuncture-moxibustion group (33 cases). In the acupuncture-moxibustion group, acupuncture was applied at Yingxiang (LI 20), Shangyingxiang (EX-HN 8), Yintang (GV 29), Shangxing (GV 23), Tongtian (BL 7) and Zusanli (ST 36). Moxibustion was applied at Zusanli (ST 36), Feishu (BL 13), Dazhui (GV 14) and Fengmen (BL 12). In the combined therapy group, on the basis of the treatment as acupuncture-moxibustion group, the catgut embedding therapy was applied at Feishu (BL 13), Fengmen (BL 12), Pishu (BL 20), Shenshu (BL 23), Zhongwan (CV 12) and Qihai (CV 6). The treatment duration was 4 weeks in the two groups. The clinical efficacy of allergic rhinitis and rhinoconjunctivitis quality of life questionnaire (RQLQ) score were observed before and after treatment as well as in the 4-weeks follow-up after the end of treatment respectively.

RESULTSThe markedly effective rate was 72.7% (24/33) in the combined therapy group and 48.4% (15/31) in the acupuncture-moxibustion group after treatment. The efficacy was similar between the two groups (P > 0.05). It was 57.6% (19/33) in the combined therapy group and was 22. 6% (7/31) in the 4-week follow-up after treatment, indicating the long-term efficacy in the combined therapy group was superior to that in the acupuncture-moxibustion group (P<0. 05). Scores of RQLO after treatment and in 4-week follow-up after treatment in both groups were improved as compared with those before treatment (all P < 0.05). In 4-week follow-up, the improvements in sleep and affection in the combined therapy group were superior to the acupuncture-moxibustion group (3.27 +/- 3.23 vs 4.61 +/- 3.56, 3.48 +/- 3.67 vs 5.81 +/- 4.15, both P < 0.05).

CONCLUSIONThe acupoint catgut embedding therapy combined with acupuncture-moxibustion therapy are safe and effective in the treatment of allergic rhinitis and display the more roles in the long-term efficacy.

Objective To explore the behaviors caused by fear of hypoglycemia in type 2 diabetic patients, and deeply analyze the causes of these behaviors, providing help for medical staff to fully understand the inner demands of diabetic patients with hypoglycemia, so as to manage the blood glucose effectively, laying the foundation of Hypoglycemia Fear Survey-behavior scale suitable for domestic type 2 diabetic patients. Methods The interpretative phenomenological analysis method was used guided by the knowledge-attitude-belief-practice and social cognitive theory, 33 patients with hypoglycemia from 5 hospitals with different levels were interviewed by semi-structured interview. Results Four themes were extracted, including excess sensitivity, caution, avoidance and compromise. The theme excess sensitivity contained three kinds of behaviors, that were meal with sensitive alertness, drug sensitivity and excessive response to the hypoglycemia, while the theme caution contained two kinds of behaviors, that were strive to blood sugar stable and must prepare food. Conclusions The results show that the fear of hypoglycemia is serious in type 2 diabetic patients, and they make many behavior change to avoid it, affecting their quality of life and glycemic management. Medical staff should attach importance to the inner feelings and behaviors of diabetic patients with hypoglycemia, and provide guidance and support after comprehensive assessment, working together with the patient to realize the effective management of blood glucose.

Objective:To investigate the expression of wild type estrogen receptor(wER)and the ex-on-5 deleted ER(variant ER,vER)in human hepatocellular carcinoma(HCC)samples,and thereafteranalyze the possibility of HCC treatment by endocrine therapy.Methods:The mRNA expressions of wERand vER were analysed from 28 cases of HCC by RT-PCR.The expression of ER at the protein level wasdetected by immunohistochemistry(IHC).Results:IHC results showed that 39.3% of the HCC speci-mens expressed ER.The mRNA of wER was detected in 89.3%(25/28)of the HCC specimens whilethat of vER was detected in 96.4%(27/28).Twenty four out of 28 HCC cases(85.7%)expressedboth wER and vER.One out of 28 patients(3.5%)expressed only wER whereas 3 patients out of 28(10.7%)expressed vER only.Conclusion:Ninety six percent(27/28)of the HCC patients expressedvER,which suggests that the expression of vER is an important event in the development of HCC.

OBJECTIVETo study spiral CT cholangiography (SCTC) before treatment in patients with obstructive jaundice due to unknown cause.

METHODSBetween October 1998 and November 2000, a total of 59 patients with obstructive jaundice of unknown cause were examined by two-phase enhanced spiral CT (eSCT). Twenty-nine of these cases were excluded because they had had T-Bil of > 34 micromol/L so that their biliary duct system could not have been visualized. The remaining 30 patients were 17 male and 13 female with an age range of 31 - 76 years (mean 56.6). Pathologically, the lesion was proven to be carcinoma of pancreatic head (n = 9), Vater's ampulla carcinoma (n = 4), extrahepatic or hilar cholangiocarcinoma (n = 13), hepatocellular carcinoma (n = 1), chronic pancreatitis (n = 1) and cholelithiasis (n = 2). SCTC was performed through intravenous injection of 20 ml 50% Cholografin within 20 min before eSCT. SCTC was undertaken with parameters of a slice thickness of 2 - 3 mm, a table feed of 3 - 5 mm, a gantry time of 0.75 sec, a reconstruction interval of 1 - 2 mm, a pitch of 1.1 - 1.2, a voltage of 120 kV, a current of 220 - 240 mA, a matrix of 512 x 512 and a scan range from the level above hepatic hilum to the third segment of duodenum within 60 - 105 min following the injection. Both reconstructed SCTC source images and later eSCT scans were considered as axial CT (ACT). Multiplanar reconstruction (MPR) was obtained immediately on the operator console. 3D imaging adopted in our study was volume rendering technology (VRT) that was processed on the Siemens 3D Virtuoso workstation within 30 min. Opacification of biliary tree (OBT) analyzed by Grades 1 to 5 and image quality (IQ) assessed by 4 scales as excellent, good, fair and poor were investigated in ACT, MPR and VRT, respectively. The correlation between total OBT, which was the highest among the 3 image methods in the same case, and T-Bil, D-Bil, ALT, severity of the biliary obstruction (SBO) as well as level of the obstruction was analyzed.

RESULTSIn OBT, no statistically significant difference was found in the five grades by the three imaging techniques (P > 0.05), the distribution of percentages being 0, 0, 13.3%, 30.0% and 56.7% in ACT, 0, 6.7%, 20.0%, 30.0% and 43.3% in MPR and 0, 0, 13.3%, 40.0% and 46.7% in VRT. The evident correlation between total OBT and D-Bil (r(s) = -0.719), ALT (r(s) = -0.544) and SBO (r(s) = 0.650) was showed. In IQ, only a statistical significance existed between ACT and MPR (P = 0.034), having the scales "excellent to poor" in percentages of 93.3%, 6.7%, 0 and 0 for ACT, 66.7%, 30.0%, 3.3% and 0 for MPR and 70.0%, 23.3%, 6.7% and 0 for VRT, respectively.

CONCLUSIONAccording to our study, spiral CT cholangiography is very useful for the evaluation of selected patients with suspected obstructive jaundice before treatment.

OBJECTIVETo investigate the clinical significance and detection of the expression of CD25- CD127- on CD4+ T cells in peripheral blood in patients with hepatitis B.

METHODSThe expression of CD25- CD127- on CD4+ T cells were measured by using flow cytometry in 53 patients with chronic hepatitis B, 53 carrier with hepatitis B virus and 26 healthy blood donors, and follow up 20 patients with HBV-DNA positive treated with interferon.

RESULTS(1) Compared with healthy controls, the expression of CD25- CD127- on CD4+ T cells in patients and carrier with hepatitis B virus were lower (Q = 4.559, P < 0.05; Q = 6.230, P < 0.05). (2) The expression of CD25- CD127- on CD4+ T cells in patients with HBV-DNA positive (n = 77) was lower than that of negative (n = 29) (t = 2.290, P = 0.024). (3) Compared with the prior treatment,the expression of CD25- CD127- on CD4+ T cells in patients with B hepatitis were lower after interferon treated with 12 weeks (t = 2.469, P = 0.024).

CONCLUSIONIt suggested that the CD25- CD127- expression on CD4+ T cells correlated with viral infections and cleared,exogenous interferon could decrease CD25- CD127- expression on CD4+ T cells.

Objective To study the efficacy and safety of T-614 in treating rheumatoid arthritis(RA). Methods Two hundred and eighty patients with active RA were randomly allocated to 3 groups:T-614 50 mg each day,25 mg each day or placebo.Clinical and laboratory parameters were analyzed at baseline,2,4,6,12, 18 and 24 weeks.Results The ACR response rate was significantly higher in the T-614 treatment group com- pared with the placebo group during the first 6 weeks.After 24 weeks,25 mg/d,50 mg/d dosage group and the placebo group showed 39.1%,61.3% and 24.2% in ACR20,23.9%,31.2% and 7.4% in ACR50 respectively.A time-response in ACR response after 24 weeks was observed,with clear superiority of the 25 mg/d and 50 mg/d dosage groups compared to the placebo,and 50 mg/d dosage group compared to 25 mg/d dosage group(P

OBJECTIVETo investigate the therapeutic results after various kinds of partial laryngectomy for patients with glottic carcinoma of the larynx.

METHODSFrom January 1980 to Mar 2004, 98 patients with glottic carcinoma of the larynx were treated by various kinds of partial laryngectomy. The types of operation varied according to stage of the lesion: vertical or frontovertical partial laryngectomy for T1b, T2 and T1a with invasion of anterior commissura, Tuker's operation or supracricoid partial laryngectomy for T1b, T2 or those with invasion of over half of contralateral cord, and extended vertical partial laryngectomy with resection of arytenoids for T3, or with invasion of ipsilateral arytenoids cartilage without involving postcricoid mucosa or posterior commissura. Totally, vertical partial laryngectomy was carried out for 76 patients, extended vertical partial laryngectomy for 7, supracricoid partial laryngectomy for 3 and Tucker's operation for 12. One stage unilateral neck dissection was performed in 5 patients and postoperative radio-therapy was supplemented to 5 (dose 60 Gy). For laryngeal function restoration, pectoro-hyomyo-flap and cricohyoidoepi glotopexy procedures were also performed for some patients. The clinical data of these patients were retrospectively analyzed.

RESULTSThe 3- and 5-year survival rate was 86.5% (64/74) and 81.7% (49/60), respectively. The total decannulation rate was 94.9% (93/98), though fifteen patients had had symptoms of aspiration. Swallowing function of all patients recovered to the normal level. The phonation of all patients was restored to various degrees and they were able to communicate socially.

CONCLUSIONThe 3- and 5-year survival rates of partial laryngectomy for patients with glottic carcinoma of the larynx are comparable to the results achieved by total laryngectomy, but the quality of life of the patents much better. Complete resection of the tumor and simultaneous preservation of respiratory and vocal function whenever possible by partial laryngectomy is very important for improving patients' life quality. With a suitable size and good blood supply, the sternohyoid muscle flap of unipedical and half-thickness instead of whole thickness is ideal in the reconstruction of laryngeal defect after vertical partial laryngectomy.

OBJECTIVEBone-marrow derived mesenchymal stem cells (BMSC) have the potential to differentiate into endothelial cells. The aim of the study was to investigate the induction process of BMSC by B16 melanoma cells in vitro and to analyze the role of VEGF-a in the process.

METHODSA co-culture system containing BMSC and B16 melanoma cells based on transwell indirect model was established, and the induction process of BMSC by B16 melanoma cells was studied in vitro.

RESULTSBMSC were isolated from the bone marrow of C57 mice. BMSC expressed CD105, CD90, CD73, CD44 and CD166, and acquired expressin of endothelial phenotype markers including VEGFR-1, VEGFR-2 and Factor VIII after co-culture with B16 melanoma cells for 48 hours. The expression level of VEGFR-2 would be double and Factor VIII threefold more by extending the co-culture time to 72 hours. In the co-culture system, B16 melanoma cells also up-regulated the expression of VEGF-a.

CONCLUSIONSVEGF-a plays a significant role in the differentiation of BMSC into cells of endothelial phenotype, therefore, is important to tumor angiogenesis.
